Description

Technical Field

[0001] This utility model relates to the field of biogas engineering, and in particular to a fermenter for biogas engineering. Background Technology

[0002] Biogas digesters are the core equipment of biogas projects. They produce biogas by decomposing organic materials (such as straw, livestock and poultry manure, and kitchen waste) through anaerobic microorganisms. They are widely used in rural energy supply, industrial waste heat recovery, and energy utilization of waste treatment plants.

[0003] A search of Chinese patents revealed publication number CN205398619U, which discloses an insulated biogas digester. The digester includes a tank body and a gas storage bladder, with the bladder located at the top of the tank body. An insulated sealing cover with a discharge hole is located at the top of the tank body. This invention overcomes the shortcomings of existing insulated biogas digesters, which suffer from easy heat loss, and provides an insulated biogas digester with good insulation performance that avoids heat loss.

[0004] Existing fermentation tanks are inconvenient to clean. Generally, fermentation tanks are cylindrical, and during the fermentation process, materials tend to settle at the bottom of the tank, requiring disassembly for cleaning. The cleaning process is cumbersome, increases workload, and reduces cleaning efficiency. Furthermore, the liquid in the fermentation tank needs to be drained during cleaning, which requires stopping use and reduces practicality. To solve the above problems, we propose a fermentation tank for biogas projects. Utility Model Content

[0005] The purpose of this invention is to provide a fermentation tank for biogas engineering, which has the advantage of being easy to clean.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fermenter for biogas engineering, comprising a tank body, with multiple supporting legs welded to the bottom of the tank body, a stirring mechanism provided inside the tank body, multiple Z-shaped plates rotatably sleeved between the inner walls of the tank body, and the Z-shaped plates overlapping in sequence, a fixing plate bolted between the inner walls of the tank body, baffles bolted to both sides of the inner wall of the tank body, with the left baffle located at the bottom of the Z-shaped plates and the right baffle located at the top of the Z-shaped plates, a fixing shell bolted to the surface of the tank body, a worm gear rotatably sleeved between the inner walls of the fixing shell, a worm wheel meshing with the surface of the worm gear, and the axis of the worm wheel fixedly sleeved with one end of the Z-shaped plate, and a rotating head bolted to one end of the worm gear.

[0007] By adopting the above technical solution, the worm is rotated by rotating the rotating head, which in turn drives the worm wheel to rotate, and the worm wheel rotates the Z-shaped plate to close the Z-shaped plate for cleaning. This method can facilitate cleaning without stopping use, greatly improving practicality and making it convenient to use.

[0008] The present invention is further configured such that: a shell is bolted to the surface of the tank, a baffle plate is slidably connected to the inner wall of the shell, and the baffle plate is slidably connected to the inner wall of the tank; a screw is threaded to the inner wall of the shell, and one end of the screw is rotatably connected to the surface of the baffle plate.

[0009] By adopting the above technical solution, the screw is moved by rotating the handwheel to open the baffle plate and discharge the residue from the tank. Since the bottom of the tank is conical, the cleaning efficiency is greatly improved. In addition, the rotating auger agitates the residue to prevent blockage, ensure smooth slag discharge, reduce the workload, and improve the cleaning efficiency.

[0010] The present invention is further configured such that: the stirring mechanism includes a motor, the motor is bolted to the surface of the tank, the output end of the motor extends into the interior of the tank and is connected to a rotating shaft via a coupling, and the rotating shaft is rotatably sleeved with the inner wall of the fixed plate, and a stirring rod is bolted to the surface of the rotating shaft.

[0011] By adopting the above technical solution, a stirring mechanism is set up. The rotation of the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the auger and stirring rod to rotate, thereby stirring the material.

[0012] The present invention is further configured such that an auger is bolted to the bottom of the rotating shaft.

[0013] By adopting the above technical solution, a screw conveyor is installed to prevent material blockage.

[0014] The present invention is further configured such that: a fixing block is bolted to the surface of the fixing shell, and the fixing block is rotatably sleeved with the surface of the worm gear; a fixing bolt is threaded to the inner wall of the fixing block, and the inner end of the fixing bolt is in contact with the surface of the worm gear.

[0015] By adopting the above technical solution, the worm gear is fixed by setting a fixing block and fixing bolts to prevent loosening and improve stability.

[0016] The present invention is further configured such that a sealing gasket is embedded in the surface of the Z-shaped plate.

[0017] By adopting the above technical solution, a sealing gasket is installed to prevent leakage.

[0018] The present invention is further configured such that a handwheel is fixedly sleeved at one end of the screw.

[0019] By adopting the above technical solution, a handwheel is provided to facilitate the rotation of the screw.

[0020] The present invention is further provided with a sealing ring between the inner wall of the tank and the flow baffle.

[0021] By adopting the above technical solution, a sealing gasket is installed to prevent leakage.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model achieves the purpose of easy cleaning by rotating the rotating head to make the worm rotate, the worm rotating to drive the worm wheel to rotate, and the worm wheel rotating to make the Z-shaped plate rotate, thus closing the Z-shaped plate for cleaning. It can be cleaned without stopping use, greatly improving practicality and making it convenient to use. 2. This utility model uses a handwheel to rotate a screw to move a baffle plate, which opens the baffle plate and discharges the residue from the tank. Since the bottom of the tank is conical, the cleaning efficiency is greatly improved. In addition, the rotating auger agitates the residue to prevent blockage, ensuring smooth slag discharge, reducing workload and improving cleaning efficiency. Attached Figure Description
