Description

Technical Field

[0001] This utility model relates to the technical field of septic tank solid waste crushing device, and more particularly to a septic tank solid waste crushing device. Background Technology

[0002] Septic tank cleaning mainly involves using a truck-mounted vacuum truck to suck the sludge out of the septic tank into a specific container, and then transporting it to a special treatment site for processing. In other words, during the septic tank cleaning process, the vacuum truck is only used as a transportation tool. Before the vacuum truck processes the septic tank, there are various solid sludge mixed in, such as paper and other debris.

[0003] Existing patent CN210170961U discloses a septic tank cleaning device, comprising a sealed box for storing sludge in a septic tank, and a separation system disposed within the sealed box for solid-liquid separation of the sludge. The separation system comprises: a filter cylinder with a mesh-like structure, arranged axially along the sealed box; a piston housed within the filter cylinder and capable of reciprocating along the filter cylinder's axial direction, used to squeeze the sludge to filter out liquid wastewater from the filter cylinder; and a power system connected to the piston for driving the piston to reciprocate along the filter cylinder. This invention uses a mesh-like filter cylinder within the box, where the piston squeezes and filters out liquid wastewater through the mesh, while the solid sludge is squeezed and stored.

[0004] Solid-liquid separation is thus achieved within the filter cartridge, resulting in a simple structure and reduced costs.

[0005] However, the existing septic tanks contain solid waste such as paper and debris, which cannot be crushed, causing pipe blockage and posing a drawback. Furthermore, the length of the solid waste crushing device for septic tanks is fixed and cannot be customized according to requirements, which limits its effectiveness. Utility Model Content

Iron chains 10 are provided on both diagonally opposite sides between the second iron plate 8 and the first iron plate 7, and the iron chains 10 are in O-shaped knots. The structure consists of an iron chain 10 connected by six O-rings. The lower end face of the second iron plate 8 has a positioning slot 14, and one side of the positioning slot 14 has a threaded groove 13. There are six threaded grooves 13 arranged in a ring. An extension shaft 6 is provided below the second iron plate 8. One end of the extension shaft 6 is fixedly connected to a connecting plate 11 that passes through it. The connecting plate 11 is fixed to the second iron plate 8 by fasteners. The structure of the motor 1 and the gearbox 2 is a prior art solution. The applicant will not provide a detailed description of the internal structure and components of the motor 1 and the gearbox 2 or their connection relationship.

[0025] The driving components include a motor 1, which drives a gearbox 2 to rotate. The gearbox 2 drives a connecting head 4 below to rotate a shaft body 5. The rotation of the shaft body 5 drives the iron chains 10 on both sides of the angle to rotate. A coupling is connected between the top plate 3 and the connecting head 4. The coupling drives the connecting head 4 to rotate the shaft body 5, which in turn drives the iron chains 10 to rotate. A top plate 3 is installed at the top of the septic tank. The top plate 3 has a motor 1 and a gearbox 2 at its top. The motor 1 drives the gearbox 2 to rotate. The rotation of the gearbox 2 drives the shaft body 5 and the extended shaft 6 to rotate. When the shaft body 5 and the extended shaft 6 rotate, they drive the iron chains 10 to rotate, thereby crushing paper, debris, etc. in the septic tank.

[0026] The fixing assembly includes a threaded rod 9. Four end feet on the surfaces of the first iron plate 7 and the second iron plate 8 are provided with through-hole threaded rod slots. The first iron plate 7 and the second iron plate 8 are connected by the threaded rod 9 through the through-hole threaded rod slots. A nut is fitted onto the threaded rod 9 outside the second iron plate 8 for fixing the chain 10. One end of the chain 10 is fitted onto the outside of the threaded rod 9, and the threaded rod 9 passes through the chain 10 to fix the chain 10 between the first iron plate 7 and the second iron plate 8. All four end feet of the first iron plate 7 and the second iron plate 8 are fixed by the threaded rod 9, and one end of the chain 10 is fitted onto the outside of the threaded rod 9 for fixing the chain 10.

[0027] The fasteners include a fastening bolt 12, which engages with and penetrates the connecting disc 11 and is inserted into the threaded groove 13 for fixation. One end of the extension shaft 6 is inserted into the positioning slot 14 for fixing the extension shaft 6 to the second iron plate 8. The extension shaft 6 is fixed by inserting one end into the positioning slot 14. At the same time, the connecting disc 11 is attached to the ground of the second iron plate 8 and is fixed by the fastening bolt 12 engaging with and penetrating the connecting disc 11 and being inserted into the threaded groove 13 for installation of the extension shaft 6. Multiple shafts can be fixed, and the installation length can be adjusted according to requirements to improve its practicality.

[0028] During operation, one end of the extension shaft 6 is inserted into the positioning slot 14 for fixation. At the same time, the connecting plate 11 is attached to the ground of the second iron plate 8. The fastening bolt 12 engages with the connecting plate 11 and is inserted into the threaded groove 13 for fixation, which is used for the installation of the extension shaft 6. The motor 1 drives the gearbox 2 to rotate. The rotation of the gearbox 2 drives the shaft body 5 and the extension shaft 6 to rotate. When the shaft body 5 and the extension shaft 6 rotate, the iron chain 10 rotates, thereby breaking up paper, debris and other materials in the septic tank to prevent pipe blockage.

[0029] Through the above steps, the shaft body 5 drives the two layers of iron chains 10 to rotate. The iron chains 10 can break up the solid waste in the septic tank, which facilitates the centralized treatment of septic tank waste and improves subsequent work efficiency. This solves the problem that existing septic tank solid waste cannot be broken up, which will cause pipe blockage. At the same time, the length of the solid waste crushing device is a fixed integrated form, which cannot be extended according to needs, and has certain limitations.
