[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model sets a hopper, a discharge port, a guide plate, a filter element, a pulse valve, an air pipe and an air hole. The guide plate blocks the air at the air inlet, and the large particles in the air fall into the hopper at the bottom through the air flow section. The air is further evenly distributed to the inside of the box through the stepped guide plates, thereby enhancing the overall filtering effect of the filter element. The pulse valve is used to rush the compressed air into the filter element from the air hole. The compressed air entering the filter element will further generate an airflow shock wave that propagates downward, thereby falling off the dust accumulated on the surface of the filter element, avoiding the situation where dust accumulation on the outside of the filter element affects the filtering effect. The pulse valve can be used to switch the dust removal equipment between the dust removal and self-cleaning working states.

[0014] 2. The utility model also provides a partition, a cylinder, a touch-pressure switch, a piston, a push rod and a spring. When dust accumulates on the outside of the filter element and causes blockage, the air from the air inlet continues to enter the box to increase the internal pressure, thereby pushing the piston to move upward until the push rod touches the touch-pressure switch. The touch-pressure switch promptly reminds the staff to clean the filter element, ensuring the normal use of the filter dust removal equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: a switchable filter cartridge bag dust removal equipment, including a box body 1, the bottom of the box body 1 is welded and fixed to the support frame 2, and the support frames 2 are fixedly connected by cross-distributed reinforcing plates, the bottom of the box body 1 is welded and fixed to the hopper 3, the hopper 3 is funnel-shaped, and the side of the hopper 3 is welded and fixed to the air inlet 4. A funnel inspection port is provided on the side of the hopper 3, and a discharge port 5 is provided at the bottom of the hopper 3. The inside of the hopper 3 is welded and fixed to several guide plates 6, and the guide plates 6 are rectangular plates with smooth surfaces. The guide plates 6 correspond to the positions of the air inlet 4, and the guide plates 6 are distributed in a stepped manner inside the box body 1. Intervals are set between adjacent guide plates 6, and the guide plates 6 are vertically distributed inside the hopper 3. The inside of the box body 1 is welded and fixed to the partition 7. The inside of the box body 1 is divided into two lower cavities by the partition 7, and the upper cavity is a buffer cavity The lower cavity is a filter cavity, the partition 7 is movably connected to the outside of the filter element 8, the inner wall of the box body 1 is fixedly connected to the side of the top plate 9, the top of the box body 1 is welded and fixed to the guardrail 10, and a pulse valve 11 is arranged on one side of the guardrail 10. The input end of the pulse valve 11 is connected to the air inlet end of the compressed air, and the bottom of the pulse valve 11 is welded and fixed to the connecting pipe 12. One end of the connecting pipe 12 extends to the buffer cavity inside the box body 1 and is welded and fixed to the air supply pipe 13. An air hole 14 is provided on the outside of the air supply pipe 13. The number of air holes 14 is the same as that of the filter element 8, and the air hole 14 is located directly above the filter element 8. The upper surface of the partition 7 is welded and fixed to the cylinder body 15, and the inside of the cylinder body 15 is fixed with the touch pressure switch 16. The inside of the cylinder body 15 is slidably connected with the piston 17, and the top of the piston 17 is welded and fixed to the push rod 18. A spring 19 is sleeved on the outside of the piston 17, and an air outlet 20 is provided on the side of the box body 1.

[0023] In embodiment 1, the filter element 8 can be a filter cartridge, and the interior of the box body 1 is divided into two lower cavities by the partition 7. The upper cavity is a buffer cavity, and the lower cavity is a filter cavity. The interior of the cylinder 15 is connected to the filter cavity, and the air outlet 20 is connected to the interior of the buffer cavity. The bottom of the hopper 3 is tilted downward from the edge to the center. There are several guide plates 6, and the guide plates 6 are evenly arranged in a linear array inside the hopper 3 and are distributed in a stepped manner. When air enters the interior of the hopper 3, it will be blocked by the guide plates 6, and large particles of dust will fall to the bottom of the hopper 3 through the air flow section. Since the guide plates 6 are distributed in a stepped manner inside the hopper 3, the filtering effect of large particles is enhanced while the air moves upward more evenly. A number of mounting holes are provided on the surface of the partition 7, and one end of the filter element 8 extends through the mounting hole to the interior of the box body 1. In the filter cavity, the top of the filter element 8 is connected with the buffer cavity in the box body 1, and the air holes 14 are evenly distributed in a linear array on the outside of the air supply pipe 13. The air holes 14 are located directly above the filter element 8. The air supply pipe 13 is connected with the interior of the pulse valve 11 through the connecting pipe 12. The piston 17 is slidably connected with the interior of the cylinder 15. The spring 19 is located between the cylinder 15 and the piston 17. When the surface of the filter element 8 is clogged with dust and the filtration efficiency is reduced, air enters the box body 1 from the air inlet 4, which increases the pressure inside the box body 1, further pushing the piston 17 to move upward until the push rod 18 moves upward and abuts against the touch pressure switch 16. The touch pressure switch 16 promptly reminds the staff to clean the dust on the filter element 8. During cleaning, the filter element 8 is cleaned alternately by jets of air through the air holes 14;

[0024] In the second embodiment, the filter element 8 can be a filter bag. In actual use, the filter cartridge and the filter bag can be replaced to realize the switching of the filter element 8. The filter cartridge and the filter bag can also be distributed according to actual conditions. When installing, the filter bag is also installed below the corresponding air hole 14. The compressed air is ejected from the air hole 14 through the pulse valve 11. The shock wave generated by the compressed air can clean the dust attached to the surface of the filter bag, and the dust falls to the bottom of the hopper 3.

[0025] Working principle: When the overall dust removal equipment is in use, air is passed from the air inlet 4 into the hopper 3. The air entering the hopper 3 will be blocked by the guide plate 6, and the large particles of dust will fall to the bottom of the hopper 3 through the air flow section. Since the guide plate 6 is distributed in a stepped manner inside the hopper 3, the large particle filtering effect is enhanced while the air moves upward more evenly. After the air is filtered by the filter element 8, the dust accumulates on the outer wall of the filter element 8, moves through the inside of the filter element 8 to the top of the partition 7 and is discharged from the air outlet 20. When the surface of the filter element 8 is clogged with dust, the filtration efficiency is reduced, and the air is discharged from the air inlet 20. The air in the opening 4 enters the interior of the box 1, which increases the pressure inside the box 1 and further pushes the piston 17 upward until the push rod 18 moves upward and abuts against the touch-pressure switch 16. The touch-pressure switch 16 promptly reminds the staff to clean the dust on the filter 8, and the compressed air is intermittently passed into the connecting pipe 12 through the pulse valve 11. Then the compressed air rushes into the filter 8 from the air hole 14, and the instantaneous shock wave generated by the compressed air propagates toward the bottom of the filter 8, thereby causing the dust accumulated on the outside of the filter 8 to fall off and fall into the bottom of the hopper 3, and the collected dust can be cleaned through the discharge opening 5.
