Description

Technical Field

[0001] This utility model relates to the technical field of pulverizing grids, and in particular to an anti-clogging pulverizing grid. Background Technology

[0002] The shredder bar is a buried sewage treatment device mainly used in municipal sewage, water conservancy projects, and pumping station systems. It is particularly suitable for buried integrated prefabricated pumping stations, preventing pump blockage and reducing environmental pollution. When the shredder bar is applied to the intercepting well chamber, the device consists of three parts: a drive unit, a shredder unit, and a bar screen unit. The drive unit uses an amphibious motor, the shredder unit cuts debris using double-axis cross blades (which are made of high-hardness imported blades), the drive unit drives the double-axis cross blades to rotate, and the bar screen unit separates large particles of waste. However, in actual use, it has been found that the waste flowing into the well chamber does not easily move towards the shredder unit, which can easily lead to blockage of the well chamber. Utility Model Content

[0003] To prevent debris from entering the interception well and clogging the well chamber, this application provides an anti-clogging crushing grid.

[0004] This application provides an anti-clogging pulverizing grid, which adopts the following technical solution: A clog-resistant shredder is installed inside a intercepting well, comprising a drive unit, a shredder unit, and a shredder unit. The shredder unit is used to block garbage from entering the intercepting well. The shredder unit is located on the side of the shredder unit away from the inlet pipe. The shredder unit includes a support box with a shredder chamber for shredding garbage. A flow passage for garbage to flow through the support box is provided through the shredder unit. A cutter shaft is provided on the support box and is rotatably mounted in the shredder chamber. A movable blade is coaxially mounted on the cutter shaft. A fixed blade that cooperates with the movable blade to shred garbage is provided on the inner wall of the support box. The drive unit is used to drive the cutter shaft to rotate. A guide plate is provided on the side of the shredder unit away from the shredder unit, and the guide plate is inclined toward the flow passage.

[0005] By adopting the above technical solution, the inclined setting of the guide plate allows the garbage entering the interception well to slide along the guide plate and flow into the crushing chamber through the flow passage for crushing by the cutter shaft. This effectively limits the accumulation of garbage in the space below the water inlet pipe, making it less likely for garbage to clog the interception well chamber.

[0006] Preferably, the grid section includes a middle baffle, side plates disposed on both sides of the middle baffle, and a bottom plate. The bottom plate is attached to the bottom of the intercepting well. The middle baffle and side plates are disposed along the edge of the bottom plate away from the water inlet pipe. The end of the side plate away from the middle baffle is connected to the inner wall of the intercepting well.

[0007] By adopting the above technical solution, the intermediate baffle and the side plate work together to provide a buffer space for the garbage entering the intercepting well through the water inlet pipe, which facilitates the subsequent gradual crushing of larger volumes of garbage.

[0008] Preferably, the side of the grille facing away from the water inlet pipe is provided with multiple reinforcing parts, and the multiple reinforcing parts are evenly arranged along the length direction of the grille.

[0009] By adopting the above technical solution, the strength of the grid section is effectively enhanced by providing support to the grid section through the reinforcing part.

[0010] Preferably, a connecting folding plate is provided between the intermediate baffle and the bottom plate, the inner side of the intermediate baffle is connected to the connecting folding plate, and the side plate is connected to the outer side of the connecting folding plate.

[0011] By adopting the above technical solution and setting up connecting baffles, support and positioning are provided for the installation of the crushing section.

[0012] Preferably, the support box is provided with a guide block on the side near the water inlet pipe, and the guide block is provided with a guide slope facing the crushing chamber.

[0013] By adopting the above technical solution and setting up guide blocks, the movement of waste toward the crushing chamber is further guided.

[0014] Preferably, the grid section has multiple filter holes evenly distributed throughout it, and the area where the filter holes are distributed is higher than the top of the inlet pipe and lower than the bottom of the inlet pipe.

[0015] By adopting the above technical solution, it is ensured that water flows through the flow passage when the flow rate is small, and can pass through the filter passage and screen out garbage when the water volume is large.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. By tilting the guide plate, the garbage entering the intercepting well can slide along the guide plate and flow into the crushing chamber through the flow passage to be crushed by the cutter shaft. This effectively limits the space below the water inlet pipe where garbage accumulates, making it less likely for garbage to clog the intercepting well chamber. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0024] This application discloses an anti-clogging shredder, which is installed inside an intercepting well 1 to treat garbage flowing into the intercepting well 1. (Refer to...) Figure 1 and Figure 2 The system includes a drive unit 2, a crushing unit 3, and a grid unit 4. The grid unit 4 is used to block garbage from entering the intercepting well 1. Multiple filter holes 41 are evenly distributed throughout the grid unit 4. The area where the filter holes 41 are distributed is higher than the top of the inlet pipe 11 and lower than the bottom of the inlet pipe 11. The grid unit 4 includes a central baffle 42, side plates 43 disposed on both sides of the central baffle 42, and a bottom plate 46. The central baffle 42 and side plates 43 are disposed along the edge of the bottom plate 46 away from the inlet pipe 11. The bottom plate 46 is fixed to the bottom of the intercepting well 1 and provides support for the central baffle 42 and side plates 43. The end of the side plate 43 away from the central baffle 42 is fixed to the inner wall of the intercepting well 1 by bolts. The central baffle 42 and side plates 43 cooperate to provide a buffer space for garbage entering the intercepting well 1 through the inlet pipe 11, facilitating the subsequent gradual crushing of larger volumes of garbage.

[0025] Reference Figure 3 Each side of the grille section 4 away from the water inlet pipe 11 is provided with multiple reinforcing parts 44. The multiple reinforcing parts 44 are evenly arranged along the length direction of the grille section 4. The number of reinforcing parts 44 depends on the actual length of the grille section 4. In this embodiment, the reinforcing parts 44 provided on the intermediate baffle 42 are tubular, and the reinforcing parts 44 provided on the side plate 43 are folded. The reinforcing parts 44 provide support for the grille section 4, effectively strengthening the strength of the grille section 4.

[0026] Reference Figure 2 and Figure 3A connecting folding plate 45 is provided between the intermediate baffle 42 and the bottom plate 46. The intermediate baffle 42 is welded and fixed to the inner side of the connecting folding plate 45, and the side plate 43 is welded and fixed to the outer side of the connecting folding plate 45. The connecting folding plate 45 provides support and positioning for the installation of the crushing part 3. At the same time, the tubular reinforcing part 44 can also make the connecting folding plate 45 less prone to deformation.

[0027] Reference Figure 3 and Figure 4 The crushing section 3 is used to crush garbage. The crushing section 3 is located on the side of the middle baffle 42 away from the water inlet pipe 11. The crushing section 3 includes a support box 31. The support box 31 is provided with a crushing chamber for crushing garbage. A flow passage 311 for garbage to flow through is opened through the support box 31. The flow passage 311 passes through the middle baffle 42. The support box 31 is provided with two cutter shafts. The cutter shafts are rotatably arranged in the crushing chamber. The cutter shafts are coaxially provided with moving blades 32. The moving blades 32 on the two cutter shafts are arranged in opposite directions and staggered. When one cutter shaft rotates, it can drive the other cutter shaft to rotate synchronously. The inner wall of the support box 31 is provided with a fixed blade 33 that cooperates with the moving blade 32 on one of the cutter shafts to crush garbage. The drive section 2 is used to drive the cutter shafts to rotate. In this embodiment, the drive section 2 is an amphibious motor. The output shaft of the drive section 2 is coaxially fixed with one of the cutter shafts.

[0028] Reference Figure 2 and Figure 3 Multiple filter holes 41 are evenly distributed throughout the grid section 4. The area where the filter holes 41 are arranged is higher than the top of the inlet pipe 11 and lower than the bottom of the inlet pipe 11. This ensures that when the flow rate is small, the water flows through the flow holes 311, and when the water volume is large, it can flow through the filter holes 41 and screen out the garbage. This prevents the top of the grid section 4 from contacting the top of the intercepting well 1. When the filter holes 41 are blocked by garbage, the water can overflow from the top of the grid section 4, ensuring the smooth flow of the intercepting well 1.

[0029] Reference Figure 2 and Figure 5 A guide plate 5 is provided on the side of the grid section 4 away from the crushing section 3. The guide plate 5 is inclined towards the flow through hole 311. The inclined arrangement of the guide plate 5 allows the garbage entering the intercepting well 1 to slide along the guide plate 5 and flow into the crushing chamber through the flow through hole for crushing by the cutter shaft, effectively limiting the space below the water inlet pipe 11 where garbage accumulates. A guide block 6 is provided on the side of the support box 31 near the water inlet pipe 11. The guide block 6 has a guide slope 61 facing the crushing chamber. The guide block 6 further guides the movement of garbage towards the crushing chamber.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
