Description

A raw material crushing and mixing device for biogas engineering

technical field

The utility model relates to a raw material crushing and mixing device for biogas engineering, in particular to a raw material crushing and mixing device for large and medium-sized biogas projects using cow dung as raw material.

Background technique

In the biogas project using cow dung as raw material, due to the large amount of long grass contained in cow dung, problems such as pipeline blockage, crusting on the top of anaerobic digester, and low gas production rate are prone to occur during the operation of the biogas project. These problems need to be solved urgently, that is, it is necessary to process the raw materials entering the anaerobic digestion tank in the pretreatment section, and crush and mix the long grass in the cow dung to avoid the above problems. There is no pulverizing and mixing device used for biogas engineering feed.

Contents of the invention

The purpose of the utility model is to provide a raw material crushing and mixing device for biogas engineering, which can meet the above-mentioned requirements of the prior art.

A raw material crushing and mixing device for biogas engineering, which is characterized in that there is a cuboid bottomless feeding barrel, the lower opening of the feeding barrel communicates with the upper opening of the propulsion mixing box through bolts, and the left opening of the propulsion mixing box , the port communicates with the adjacent cuboid-shaped extrusion box on the right side through bolts; there is a discharge box on the left side of the extrusion box, and the two are also connected to each other; push the mixing box, the extrusion box and the discharge box The boxes are all on the bracket, and a transmission rod runs through the middle of the push mixing box, extrusion box, and discharge box. There are screw ribs on the transmission rods in the push mixing box and extrusion box. It is connected with the left end of the transmission rod, and the two ends of the transmission rod are installed on the bearing seat; a cutting screen with a hole is installed at the left opening of the extrusion box, and a cutting blade is installed on the transmission rod, between the cutting blade and the cutting screen There is a spring on the transmission rod between them, a water inlet pipe is installed on the top of the feeding barrel, there is a drain valve at the bottom of the push mixing box, there is a sealing sleeve where the transmission rod passes through the right wall of the push mixing box, and there is a discharge valve on the left side of the discharge box. bezel.

The utility model uses a spring to control the size of the gap between the cutting blade and the cutting screen, which can ensure an appropriate gap, and prevents the long grass from wrapping around the cutting blade while crushing the long grass in the material. The use of the screw edge to push the material increases the agitation function, and at the same time increases the flow rate of the material, prevents the dry manure from blocking the nozzle of the water inlet pipe of the equipment, and improves the raw material processing capacity.

Detailed ways

The utility model has a cuboid bottomless feeding barrel 1, the lower opening of the feeding barrel 1 communicates with the upper opening of the cuboid propelling mixing box 2 through bolts, and the left side opening of the propelling mixing box 2 is passed through the bolt. It communicates with the extruding box 3 with the opening on the right side of the cuboid adjacent to it, and the left side of the extruding box 3 has a discharge box 4, and the two are also connected to each other; The boxes 4 are all on the support 5, and a transmission rod 6 runs through the middle of the pushing mixing box 2, the extrusion box 3, and the discharge box 4. The shaft of the motor 7 is connected to the left end of the transmission rod 6 through the pulley 8 and the transmission belt 9, and the two ends of the transmission rod 6 are mounted on the bearing housing 10; Screen 11, a cutting blade 12 is installed on the transmission rod 6, a spring 13 is installed on the transmission rod 6 between the cutting blade 12 and the cutting screen 11, a water inlet pipe 14 is installed on the top of the feeding barrel 1, and there is a sewage discharge at the bottom of the propulsion mixing box 2 Valve 15, transmission rod 6 pass through the right wall place that pushes mixing box 2 and seal sleeve 16 is arranged, and the left side of discharge box 4 has discharge baffle plate 17.

When using the utility model, the material cow dung is dropped into from the upper opening of the feed barrel 1, so that the water inlet pipe 14 on the feed barrel 1 top is connected with fermented biogas slurry or warm water (such as geothermal water, sun-baked water) water), and make the fermented biogas slurry or warm water enter the propulsion mixing box 2. Turn on the motor 7, and drive the transmission screw 6 through the pulley 8 and the transmission belt 9, so that the material and the added fermented biogas slurry or warm water are fully stirred and mixed through the screw flight on the transmission screw 6, and the screw flight along the horizontal direction is passed through the transmission screw 6. Push it to the cutting blade 12 and the cutting screen 11 in the extrusion box 3. Under the action of a certain propulsion speed and rotational flow rate, the material passes through the cutting blade 12 and the cutting screen 11 to chop the long grass in the cow dung. And be extruded in the discharge box 4. The discharge baffle plate 17 on the left side of the discharge box 4 can prevent the material from overflowing, and the gravel contained in the cow dung is deposited at the bottom of the mixing box 2, and is removed by the sewage outlet 15.

The utility model can use warm liquid and fermented biogas slurry to return to dilute the material. On the one hand, the biogas solution can be used for secondary fermentation, which saves water resources and improves the utilization efficiency of resources. On the other hand, it reduces the subsequent fermentation. Energy requirements for tank warming, reducing energy consumption.
