Description

Top pressure two-combined glass fiber reinforced plastic pool body safety biogas digester

Technical field:

The utility model belongs to a glass fiber reinforced plastic biogas digester, which belongs to a top-pressure two-combined glass reinforced plastic pond body safety biogas digester.

Background technique:

It is convenient and economical to use biogas as fuel in rural areas. The residue after fermentation can also be used as fertilizer. The fermented fertilizer has killed a large number of parasite eggs and viruses, and has played a good role in protecting the urban and rural environment. Therefore, The use of biogas in rural areas is becoming more and more common, and the construction of biogas pits has entered a new era of safety and science from simple construction. Among them, there are many kinds of biogas pits made of fiberglass, which provide a certain guarantee for the safe use of biogas, but there are still There are some shortcomings, such as: the existing glass fiber reinforced plastic pool body is divided into upper and lower hemispheres and upper and lower half ellipsoids. The combined pool body has inlet and outlet pipes, and the water pressure room and the pool body are in the form of bonding, and the joint surface of the connection is small. And it is a curved surface, it is difficult to guarantee the sealing performance and connection strength, and there are certain safety hazards. The other is the form of combining the upper and lower hemispheres or the upper and lower elliptical hemispheres respectively. This form has too many combined surfaces and no sealing Parts, the sealing performance of the pool body is difficult to be guaranteed. In addition, because the bottom of the pool body is hemispherical or semi-elliptical, the bottom of the pool body is easily damaged. The above-mentioned discharge port is also used as an exit for personnel, which may easily cause children to accidentally fall into it and paint residues in the pool. Poisoning occurs due to exhaustion of biogas, so it needs to be improved.

Utility model content:

The purpose of this utility model is to provide a kind of production, transportation, install conveniently, pool body sealing is reliable and safe to use safety biogas pool of top pressure two combined glass fiber reinforced plastic pool body.

The technical scheme of the utility model is shown in Figure 1. The lower pool body 1 is a conical body with a large top and a small bottom. The upper edge is a whole with a flange, and the bottom is raised upwards. The upper tank body 2 of the blue plate is evenly connected by bolts 8, there is a sealing strip 9 between the two flanges, a large through hole is opened on the top of the upper tank body 2, and nuts and sealing strips 9 are pre-embedded around the edge of the through hole. There are screw holes around the bottom of the room 6, which are matched with the embedded nuts around the large hole of the upper tank body 2, and the water pressure room 6 is fixed with screws 10, and the center of the bottom of the water pressure room 6 is symmetrical with a cone with a sealing ring and the size of the cover. Cylindrical feed pipe 3 and discharge pipe 4, on the tapered hole protruding upwards in the center of the water pressure room 6, there is an air outlet pipe 5, the upper side wall of the water pressure room 6 is provided with an overflow port 7, the water pressure Room 6 is provided with a cover.

The utility model has the advantages that: the components of the biogas pool are all plane connections, and a sealing ring is provided to ensure the reliability and safety of the sealing connection. Easy to transport and install. The upper end of the feed pipe can be equipped with an external joint for easy feeding. The minimum diameter of the discharge pipe is slightly larger than that of the discharge submersible pump, which is convenient for the discharge submersible pump to work, and at the same time prevents children from falling into the pool. The water pressure is 6 It is detachable. When the slag needs to be removed, the water pressure room 6 is removed. At this time, the biogas in the pool has been completely discharged. It is safer for personnel to go down to the pool for cleaning. The bottom of the lower pool body is raised upwards, which can reduce damage to the bottom.

Description of drawings:

Among them: 1. Lower tank body; 2. Upper tank body; 3. Feed pipe; 4. Discharge pipe; 5. Air pipe; 6. Water pressure room; 7. Overflow port; 8. Bolt; 10. Screws.

Detailed ways:

The utility model is implemented according to the above-mentioned technical scheme, wherein the upper pool body, the lower pool body, the water pressure room, the feeding pipe and the discharging pipe can all be produced by molding with glass fiber reinforced plastics, and the same parts of the product can be stacked together, which saves stacking space and facilitates transportation , Easy to install, time-saving, because the pool body uses a sealing strip, it is safe and reliable to use. The largest part of the utility model is the lower pool body, with a diameter of about 2 meters and a height of about 1 meter.
