Description

Industrial fish pond sewage system device

Technical field:

The utility model belongs to the technical field of aquaculture, and relates to industrial fish ponds, in particular to a sewage discharge system device for industrial fish ponds that can automatically regulate water levels, effectively remove dirt in the ponds, and realize sewage separation.

Background technique:

At present, in the existing industrial fish ponds, reinforced concrete or brick fish ponds are mostly used, not only the surface algae and stains are difficult to clean, but also the appearance is very bloated; usually there are many dead spots in the pond, which are easy to accumulate pollution, which seriously affects the health of fish. Growth; in the existing industrial fish pond sewage system installation, the sewage outlet is not set properly, and the sewage outlet is usually designed with a small flow cross-section, or the sewage grille is too close to the sewage pipe mouth, and the water is often discharged due to excessive flow velocity and poor physical condition. Weaker small fish are easy to adsorb on the sewage grille, and in serious cases, the pool water can hardly be released; the water level control is unreasonable, and fish ponds often empty or overflow; the diameter of the sewage pipe is too small, which increases the discharge time and often It is difficult to unblock due to fish stuck in the pipe, and in serious cases, the fish pond cannot be used; the setting of the sewage valve is unreasonable, and the usual practice is to set the valve at a low position in the fish pond, which is not only inconvenient to open and maintain, but also the foul smell in the valve well is not suitable for cleaning. , affecting operation and use; usually sewage separation is not considered during sewage discharge, and if fish farming water is reused, it is necessary to increase the intensity of water treatment. Therefore, the original industrial fish ponds have many disadvantages such as low safety, large accumulation of dirt, difficult operation, poor utilization of equipment and high water treatment intensity.

The purpose of this utility model is: to overcome the deficiencies of the prior art, to provide an industrial fish pond sewage system that can automatically regulate the water level, effectively remove the sewage in the pond, and realize the separation and discharge of sewage. device.

Invention content:

The purpose of this utility model is specifically implemented by the following scheme:

A sewage discharge system device for industrialized fish ponds, comprising a sewage outlet for industrialized fish ponds, a water level pipe, and a discharge structure, and is characterized in that: a sterilizer is arranged between the mouth of the sewage pipe (17) and the sewage grid (5). Force chamber (19), the other end of blowdown pipe (17) is provided with a dirt accumulation chamber (15), and the top of dirt accumulation chamber (15) is connected by diversion standpipe (16), diversion horizontal pipe (9) and is " n" type structure, a sewage elbow (14) with a flange (25) is arranged at the horizontal outlet of the sewage chamber (15), and a plugging pipe (13) is inserted in the sewage elbow (14).

The main body of the industrialized fish pond is made of glass fiber reinforced plastic, and the inner layer is made of non-toxic, food-grade glass fiber reinforced plastic material. The shape of the fish pond is made into a circle; The arc pool corner (3), the bottom of the pool (4) slopes towards the central sewage outlet; the sewage outlet (26) is cylindrical, its area is 5 to 10 times larger than the section of the sewage pipe (17), and its cylinder height is slightly greater than the sewage discharge The grille (5) is thick, and the stilling chamber (19) in the shape of a rounded table has a certain height (10-15 cm) below it.

The bottom of the stilling chamber (19) is connected with the sewage pipe (17), and the sewage pipe (17) is provided with a section of circular pipe near the end of the sewage pipe (22), and its diameter is 2 to 3 times larger than the sewage pipe to form a sewage chamber (15). Be "n" type structure between three pipelines of diversion pipe (9,16) above sewage chamber (15), diversion horizontal pipe (9) tube bottom is set apart from fish pond top 15 centimeters.

An evacuation pipe (8) of an "n" type structure is arranged above the diversion horizontal pipe (9), and the evacuation pipe (8) stretches into the fish pond, and a plastic hose (7) of the evacuation nozzle (24) is overcoated. The pipe collar (6) is fastened, and the water depth is controlled according to the requirements of the depth of the breeding water.

At the horizontal outlet of the sewage chamber (15), near one end of the sewage pipe (17) of the sewage channel (22), a sewage elbow (14) with a flange (25) is arranged, and the whole sewage elbow (14) ) is located in the sewer (22).

Insert a plugging pipe (13) in the sewage elbow (14), and its top is at least lower than the pool top height. Insert or extract the plugging pipe (13) to control the discharge of pool water, and the overflow grille (23) is installed on the sewage channel (22) simultaneously.

The remarkable effect of the utility model is: since the main body of the fish pond is made of non-toxic, food-grade fiberglass material, with a hard and smooth surface, the adhesion of dirt in the pond is reduced. Since the top is made into a pool roof overturning eaves (1), the deformation of the fish pond is prevented, and the strength of the fish pond is increased. Since the bottom of the pool (4) has a cylindrical sewage outlet (26) with a sewage grid (5) installed, there is a rounded frustum-shaped cutting chamber between the sewage grid (5) and the sewage pipe (17). (19), so the cross-section of water flow has been increased, and the flow velocity has been reduced, which not only prevents fish from escaping and slows down the adsorption of fish on the sewage grille (5), but also makes sewage or drainage smooth. Because the sewage elbow (14) adopts two kinds of interfaces, its flange interface is connected with the sewage pipe (17) drawn from the sewage chamber (15), and the whole elbow is installed in the sewage channel, so the socket interface The plug-in pipe (13) can be installed or disassembled, which can replace the valve for pool water discharge, and the operation can be easily completed on the ground (21). Even if the sewage elbow (14) is worn out, it is easy to replace, and the cost and maintenance cost are much lower than that of the valve. many. Since a sewage chamber (15) is added between the sewage pipe and the sewage elbow (14), and an "n" type siphon overflow pipe formed by three diversion pipes is added above the sewage chamber (15), when the main water inlet pipe (11), the branch inlet pipe (10) continuously supplies water, and the water inlet valve (18) controls the flow, so that a certain flow passes through the fish pond, and some metabolic waste is taken out of the pond through the sewage pipe (17) along with the water flow, and enters the fish pond. In the sewage chamber (15), when the plug-in pipe (13) is installed on the sewage elbow (14), the water flow enters the return pipe (12) through the "n" type siphon overflow pipe, and because the water flow in the diversion standpipe (16) rises slowly, and some large and heavy dirt particles are deposited and concentrated in the dirt accumulation chamber (15); when the insertion tube (13) is pulled out, the dirt accumulation chamber (15) can be quickly and effectively This reduces the pollution degree of the backwater and the intensity of water treatment, prolongs the discharge time, reduces the number of sewage discharges, and quickly discharges sewage, saves time and water. Because there is an evacuation pipe (8) above the "n" type siphon overflow pipe and stretches in the fish pond, the evacuation nozzle (24) controls the water depth by the height of the flexible plastic pipe through the pipe collar (6), when the siphon water level drops and When exposed to the water surface, the air siphon is automatically stopped due to the extraction of air, so after the water depth is set, the water level of the siphon is monitored in real time through the feedback information of the evacuation nozzle (24), so that the water level is automatically maintained without personnel management.

To sum up, the industrial fish pond sewage system device of the utility model better realizes the purpose of the utility model.
