Description

Technical Field

[0001] The utility model relates to the technical field of septic tanks, in particular to a septic tank waste residue filtering and cleaning structure. Background Art

[0002] Septic tanks are equipment that treats feces and filters and precipitates them. The principle is that the solidified matter decomposes at the bottom of the tank, and the hydrated matter on the upper layer flows into the pipe to prevent pipe blockage, giving the solidified matter (feces and other garbage) sufficient time to hydrolyze. Septic tanks refer to small treatment structures that separate and precipitate domestic sewage and perform anaerobic digestion of sludge.

[0003] Traditional septic tanks are constructed by digging holes and laying bricks underground. After years of improvement and use, they are currently made of fiberglass and buried underground. Most of the people who use septic tanks are farmers. After a period of fermentation and decomposition in the septic tank, the fermented feces need to be cleaned out and new feces added for fermentation.

[0004] Traditionally, the feces are cleaned out using a dung shovel tool through a round hole reserved at one end of the septic tank. However, the fermented feces has a high water content, which not only makes cleaning inefficient, but the liquid in the feces can also be used as liquid organic fertilizer after fermentation. When the fermented material is cleaned out and piled in an open space waiting to be fertilized on the ground, the internal liquid will flow out, evaporate, and seep into the ground, resulting in the problem of some liquid organic fertilizer being wasted. Utility Model Content

[0005] The purpose of the utility model is to provide a septic tank waste residue filtering and cleaning structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a septic tank waste residue filtering and cleaning structure, comprising a septic tank body and a cleaning structure; the cleaning structure is arranged inside the septic tank body, and the cleaning structure comprises a filtrate pipe welded on the inner wall of the septic tank body, an extraction pipe welded to the bottom end of the filtrate pipe, a spiral blade shaft rotatably connected to the top of the filtrate pipe, a motor arranged at the top of the filtrate pipe, a discharge head welded to one side of the filtrate pipe and a blocking plate welded to one end of the discharge head; the rotating shaft of the motor is connected to the spiral blade shaft, and the spiral blade shaft is located in the extraction pipe and the filtrate pipe.

[0007] By adopting the above technical scheme, the motor drives the rotating spiral blade shaft to extract the waste, and the waste first enters the extraction pipe and enters the filtrate pipe. The waste is transported into the discharge head and is blocked and discharged by the blocking piece, so that the waste is blocked in the filtrate pipe and squeezed. The waste liquid is filtered and discharged from the filtrate pipe, thereby achieving the effect of filtering, dehydrating and discharging the waste, improving the efficiency of cleaning the waste in the septic tank body, and the waste liquid filtered and refluxed to the inside can be collected and utilized to avoid waste.

[0008] Preferably, a rotating cylinder is welded to the top of the septic tank body, a stirring rod is rotatably connected to the inner wall of the rotating cylinder, a guide head is welded to the top of the septic tank body, and a belt is connected to the top of the stirring rod, the top of the guide head and the rotating shaft of the motor.

[0009] By adopting the above technical solution, the stirring rod is installed by rotating, and the stirring rod is driven by the motor-driven belt to rotate synchronously, so that the waste deposited by internal fermentation can be stirred, so that the waste mixture has good fluidity, which is convenient for the extraction pipe to extract, dehydrate and discharge, and avoids the problem of adhesion between waste materials and difficulty in extraction.

[0010] Preferably, a filter baffle is welded to the inner wall of the septic tank body, and a feed inlet and a filtrate inlet are respectively welded to the top of the septic tank body on both sides of the filter baffle.

[0011] By adopting the above technical solution, two independent spaces are formed by welding filter partitions, which can block and filter the feces on one side. During the fermentation process, the supernatant will be filtered into the other space for storage, realizing the functions of fermentation and storage. During use, liquid organic fertilizer can be taken out more conveniently for fertilization, thereby improving the convenience of using fermented fertilizers and the practicality of the device.

[0012] Preferably, the pitch length of the spiral blade shaft at the filtrate pipe is shorter than the pitch length of the spiral blade shaft at the extraction pipe, and the bottom end of the extraction pipe is trumpet-shaped.

[0013] By adopting the above technical solution and setting the pitch of the spiral blade shaft at different positions, the bottom spiral blade shaft is responsible for extracting the waste into the extraction tube. After entering the top spiral blade shaft, the waste enters a relatively smaller space, and the front end is subjected to resistance from the blocking piece, which increases the force on the waste and squeezes out the waste liquid, thereby achieving the effect of extrusion dehydration.

[0014] Preferably, the discharge head is communicated with the filtrate tube, and the diameter of the blocking plate is slightly smaller than the inner diameter of the discharge head.

[0015] By adopting the above technical solution and using a blocking plate with a slightly smaller diameter than the discharge head, the waste is discharged and accumulated at the discharge head, so that the discharge volume is less than the extraction volume, and the waste at the filtrate pipe is subjected to pressure for dehydration, thereby ensuring the normal use of the normal filtering function.

[0016] Preferably, the stirring rod is located at the bottom end of the extraction tube, and the stirring blades of the stirring rod are in an inverted cone shape as a whole.

[0017] By adopting the above technical solution, the bottom of the extraction tube is stirred in an inverted cone shape to ensure that the rotation does not touch the extraction tube, and the surrounding waste can be broken up and mixed to improve fluidity.

[0018] Preferably, the belt is a rough round belt made of polyurethane, and the two belts are respectively passed through the guide holes in the middle of the guide head.

[0019] By adopting the above technical solution, a rough round belt made of high-strength polyurethane material is used as the belt, so that the belt can change the transmission direction along with the guide hole in the guide head, so as to use the motor to drive the stirring rod to improve the linkage between equipment and improve the power utilization and practicality of the motor.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] (1) The motor drives the rotating spiral blade shaft to extract the waste. The waste first enters the extraction pipe and enters the filtrate pipe. The waste is transported into the discharge head and is blocked and discharged by the blocking sheet, so that the waste is blocked in the filtrate pipe and squeezed. The waste is squeezed and the waste liquid is filtered and discharged from the filtrate pipe, thereby achieving the effect of filtering, dehydrating and discharging the waste, improving the efficiency of cleaning the waste in the septic tank body, and the waste liquid filtered and refluxed to the inside can be collected and utilized to avoid waste;

[0022] (2) By welding the filter partition to form two independent spaces, the feces on one side can be blocked and filtered. During the fermentation process, the supernatant will be filtered into the other space for storage, realizing the functions of fermentation and storage. During use, liquid organic fertilizer can be taken out more conveniently for fertilization, thereby improving the convenience of using fermented fertilizers and the practicality of the device.
