The inside of the inlet pipe 11 is connected with the inside of the box 1. A plurality of honeycomb inclined pipes 111 are fixedly arranged in the inlet pipe 11, and a cover plate 112 is hingedly connected to the top of the inlet pipe 11. A water outlet pipe 12 is fixedly arranged on one side of the bottom of the box 1 along its length direction. The water outlet pipe 12 is connected with the inside of the box 1, and a valve 121 is fixedly arranged on the water outlet pipe 12. A sealing door 13 is hingedly arranged on the side wall of the box 1 along its width direction below the filtering mechanism 3, and a sealing gasket (not shown in the figure) is fixedly arranged on the side of the sealing door 13 close to the filtering mechanism 3 along its circumferential surface. The crushing mechanism 2 is arranged at the top of the box 1, and is used to crush large solid substances in the wastewater. The filtering mechanism 3 is arranged below the crushing mechanism 2, and is used to filter the wastewater.

[0024] When in use, open the cover 112, pour the wastewater from the water inlet pipe 11, first pass through the honeycomb inclined tube 111 for preliminary filtration, then start the crushing mechanism 2, the crushing mechanism 2 can crush the large solid matter in the wastewater, and then reach the filtering mechanism 3, the filtering mechanism 3 can filter the crushed solid matter, leaving the crushed solid matter, and the filtered wastewater flows out through the outlet pipe 12 for subsequent operations to reduce the blockage of the outlet pipe 12.

[0025] Reference Figure 1 and Figure 4The crushing mechanism 2 includes a stirring rod 21, a first blade 22, a second blade 23, a third blade 24, and a first driving assembly 25. The stirring rod 21 is arranged along the height direction of the box body 1 and is arranged at the center position of the top end in the box body 1. The top end of the stirring rod 21 passes through the top wall of the box body 1 and is rotatably connected thereto. There are multiple groups of first blades 22, and three groups in this embodiment. The three groups of first blades 22 are arranged at intervals along the height direction of the stirring rod 21. There are two first blades 22 in each group, and the two first blades 22 are symmetrically arranged on both sides of the stirring rod 21 along the length direction of the box body 1, and one end of the first blade 22 along its length direction is fixedly connected to the stirring rod 21. Each first blade 22 has serrations. There are multiple second blades 23, and four in this embodiment. The four second blades 23 are centered on the stirring rod 21 and are evenly fixed at the bottom end of the stirring rod 21 along the circumference of the stirring rod 21. The four second blades 23 are all bent downward, and the bending angle is 5-10° with the stirring rod 21 as the reference line. The number of the third blades 24 is also multiple, and in this embodiment, there are four. The four third blades 24 are fixedly arranged on the top surfaces of the four second blades 23 along the circumference of the stirring rod 21 with the stirring rod 21 as the center. The four third blades 24 are all bent upward, and the bending angle is 60-80° with the stirring rod 21 as the reference line. The first driving assembly 25 includes a first motor 251, the first motor 251 is fixedly arranged on the outer top wall of the box body 1, and the output shaft of the first motor 251 is fixedly connected to the end of the stirring rod 21 extending out of the box body 1.

[0026] When the wastewater enters the box body 1, the first motor 251 is started, and the output shaft of the first motor 251 can drive the stirring rod 21 to rotate, and then drive the first blade 22, the second blade 23, and the third blade 24 to crush the large solid matter in the wastewater. The bent shape of the second blade 23 and the third blade 24 can effectively increase the length of the blade and improve the crushing ability. The bending direction is consistent with the direction of the whipping flow field, which can reduce the whipping vortex. The second blade 23 bends downward and the third blade 24 bends upward, which can form a circulating convection in the whipping process for the large solid matter, so that the large solid matter in all directions in the box body 1 can be fully crushed, and finally the crushed large solid matter falls on the filtering mechanism 3, and the wastewater flows out through the filtering mechanism 3, and the large solid matter in the wastewater is fully crushed, thereby reducing the blockage of the outlet pipe 12.

[0027] Reference Figure 1 and Figure 4The filter mechanism 3 includes a filter plate 31, a screw rod 32, a slider 33, a stop rod 34, a scraper 35, and a second drive assembly 36. The filter plate 31 is arranged along the length direction of the box body 1, and the filter plate 31 is fixed at the bottom end of the box body 1, and one end of the filter plate 31 along its length direction is inclined toward the outlet pipe 12. A plurality of filter holes 311 are evenly provided on the filter plate 31. Grooves 312 are provided at both ends of the filter plate 31 along its length direction. There are two screw rods 32, and both screw rods 32 are arranged on the filter plate 31, and the two screw rods 32 are respectively arranged at both ends of the filter plate 31 along its width direction. Both screw rods 32 are arranged along the length direction of the filter plate 31. One end of the screw rod 32 is rotatably connected to the side wall of the box body 1, and the other end passes through the side wall of the box body 1 and is rotatably connected thereto. There are two sliders 33, and the two sliders 33 correspond to the two screw rods 32 one by one, and the two sliders 33 are respectively threadedly connected to the two screw rods 32. There are two limit rods 34, which correspond to the two screw rods 32. The limit rods 34 are arranged parallel to the screw rods 32, and the limit rods 34 pass through the slider 33 and are slidably connected to the slider 33, and the two ends of the limit rods 34 are fixedly connected to the side wall of the box body 1. The scraper 35 is arranged along the width direction of the filter plate 31, and the scraper 35 is arranged between the two sliders 33, and the two ends of the scraper 35 along the length direction are fixedly connected to the two sliders 33. A plurality of bristles 351 are evenly fixed on the side of the scraper 35 close to the filter plate 31, and the bristles 351 abut against the filter plate 31. The second driving assembly 36 drives the two screw rods 32 to rotate.

[0028] Start the second drive assembly 36, which can drive the two screw rods 32 to rotate. Since the slider 33 and the screw rod 32 are threadedly connected and the limiting rod 34 has a limiting effect, the slider 33 can only move along the length direction of the screw rod 32, thereby driving the bristles 351 to clean the filter plate 31, and the solid matter that falls on the filter plate 31 is swept into the two grooves 312, thereby reducing the formation of crystals of solid matter on the filter plate 31 to block the filter holes 311.

[0029] Reference Figure 1 and Figure 5 The second driving assembly 36 includes a second motor 361, a first pulley 362, a second pulley 363, and a belt 364. A mounting plate 365 is fixedly provided on the outer wall of the box body 1 below the end of one of the screw rods 32 extending out of the box body 1. The mounting plate 365 is arranged parallel to the screw rod 32. The second motor 361 is fixedly provided on the mounting plate 365, and the output shaft of the second motor 361 is fixedly connected to the end of the screw rod 32 extending out of the box body 1. The first pulley 362 is sleeved on the output shaft of the second motor 361 and is fixedly connected thereto. The second pulley 363 is sleeved on the end of the other screw rod 32 extending out of the box body 1 and is fixedly connected thereto. The belt 364 is sleeved on the first pulley 362 and the second pulley 363.

[0030] Start the second motor 361. The second motor 361 can drive the screw 32 fixed thereto to rotate, and can also drive the first pulley 362 to rotate. Due to the connection of the belt 364, the second pulley 363 can also rotate, thereby causing the other screw 32 to rotate, thereby realizing the movement of the slider 33, so that the bristles 351 clean the filter plate 31.

[0031] The operating principle of the present application is as follows: the wastewater is poured in from the water inlet pipe 11, and first the wastewater is preliminarily filtered through the honeycomb inclined tube 111, and then the first driving component 25 is started, which can drive the stirring rod 21 to rotate, and then the first blade 22, the second blade 23, and the third blade 24 break the solid matter in the wastewater, and the broken solid matter will fall on the filter plate 31, and the wastewater flows out through the filter plate 31 and the water outlet pipe 12. In addition, the second driving component 36 can be started to make the bristles 351 clean the filter plate 31 to reduce the blockage of the filter plate 31. At the same time, the solid matter in the wastewater is broken and filtered, and the blockage of the water outlet pipe 12 can also be reduced.

[0032] Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
