Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a dust removal and environmental protection device for lime production. Background Technology

[0002] The lime production process, especially the stage of calcining limestone to produce lime (calcium oxide), generates a large amount of dust. If this dust is directly emitted with the exhaust gas from the calcining furnace, it will pollute the environment.

[0003] Traditional lime dust removal uses water spraying, but this method wastes a lot of water, and the dust particles stick together and are difficult to clean. Dry vacuuming avoids water waste, but because lime production generates a large amount of dust, the filter bags quickly become clogged with dust, requiring frequent cleaning.

[0004] Most existing methods for cleaning dust collector filter bags involve tapping them, but this only cleans one part of the filter bag, resulting in low efficiency and poor cleaning effect. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing dust removal devices for lime production have low cleaning efficiency and poor cleaning effect on dust filter bags.

[0006] To solve the above problems, the technical solution of this utility model is as follows: a dust removal and environmental protection device for lime production, including a treatment box, a box cover on the top of the treatment box, an air inlet pipe on the side, an exhaust pipe on the box cover, a filter assembly installed inside the treatment box, and a discharge pipe at the bottom. The filter assembly includes a bracket installed on the top of the box cover, a filter bag sleeved on the outside of the bracket, and a vibrating assembly on the inside. The vibrating assembly includes multiple circular plates rotatably mounted on the bracket. Two connecting rods are symmetrically fixed to one side of each circular plate, and a crossbar is fixed to the other side. A striking plate is fixed to the end of each connecting rod. A mounting seat is provided at the center of the multiple circular plates. A sleeve sleeved on the outside of the crossbar is hinged to the outside of the mounting seat. A driving assembly for driving the mounting seat to move is installed on the top of the box cover.

[0007] Furthermore, ear plates are fixed to both the front and rear sides of the box cover, and the ear plates are installed on the outside of the processing box by screws.

[0008] Furthermore, the bracket includes a top plate and a bottom plate, with multiple vertical rods fixedly connected between the top plate and the bottom plate. The top plate has a through hole corresponding to the position of the exhaust pipe, and a fixing ring is fixedly connected to its bottom surface. The outer diameter of the fixing ring is the same as the diameter of the bottom plate.

[0009] Furthermore, the opening of the filter bag is fitted onto the outside of the fixing ring, and the filter bag is installed on the outside of the fixing ring by a cable tie.

[0010] Furthermore, a positioning rod is fixed between two adjacent vertical rods, and the circular plate is rotatably mounted on the outside of the positioning rod.

[0011] Furthermore, the drive assembly includes a motor mounted on one side of the top of the cover and a pull rod fixedly mounted on the top of the mounting base. The pull rod extends above the cover. A cam is mounted on the output shaft of the motor. A column is provided on one side of the motor. A fixed shaft is fixedly connected to the front end of the column. A horizontal plate is rotatably mounted on the outside of the fixed shaft. A fixed frame sleeved on the outside of the pull rod is fixedly connected to one end of the horizontal plate. Both the horizontal plate and the fixed frame are provided with sliding grooves. A fixed rod passing through the sliding groove is fixedly connected to the edge of the front end face of the cam. Limiting blocks passing through the sliding groove are fixedly connected to the front and rear sides of the pull rod.

[0012] Furthermore, a limiting sleeve sleeved on the outside of the tie rod is fixedly connected to the bottom of the top plate.

[0013] Furthermore, a valve is installed on the discharge pipe, and a collection box is connected to its bottom. The collection box has a discharge port at the front end, and a sealing cover is installed at the discharge port.

[0014] The advantages of this invention compared to existing technologies are as follows: The motor drives the cam to rotate, causing the pull rod to move the mounting base and sleeve up and down. This further causes multiple circular plates and connecting rods to reciprocate around the positioning rod. The connecting rods drive the beater plate to rotate, achieving multi-point beating of the filter bag. This can quickly remove dust from the surface of the filter bag, thereby improving the cleaning efficiency of the filter bag. The multi-point beating can improve the cleaning effect of the filter bag. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 As shown, a dust removal and environmental protection device for lime production includes a treatment box 1. The treatment box 1 has a box cover 2 on the top and an air inlet pipe 3 on the side. The box cover 2 has an exhaust pipe 4. A filter assembly is installed inside the treatment box 1. A discharge pipe 5 is provided at the bottom. Ear plates 14 are fixed to both the front and rear sides of the box cover 2. The ear plates 14 are installed on the outside of the treatment box 1 by screws. A valve is installed on the discharge pipe 5, and a collection box 24 is connected to its bottom. The front end of the collection box 24 has a discharge port, and a sealing cover 25 is installed at the discharge port.

[0022] Connect the flue gas duct to the inlet pipe 3. After the flue gas is filtered, it is discharged through the exhaust pipe 4. The filtered dust particles are discharged into the collection box 24 through the discharge pipe 5. Open the sealing cover 25 to discharge the dust.

[0023] like Figure 2 As shown, the filter assembly includes a bracket 6 installed on the top of the inner cover 2. A filter bag 7 is sleeved on the outside of the bracket 6, and a vibrating assembly is provided on the inside. The vibrating assembly includes multiple circular plates 8 rotatably mounted on the bracket 6. Two connecting rods 9 are symmetrically fixed to one side of the circular plate 8, and a crossbar 10 is fixed to the other side. A striking plate 11 is fixed to the end of the connecting rod 9. A mounting seat 12 is provided at the center of the multiple circular plates 8. A sleeve 13 is hinged to the outside of the mounting seat 12 and sleeved on the outside of the crossbar 10. A drive assembly for driving the mounting seat 12 to move is installed on the top of the cover 2.

[0024] like Figure 3As shown, the bracket 6 includes a top plate 6.1 and a bottom plate 6.2. Multiple vertical rods 6.3 are fixedly connected between the top plate 6.1 and the bottom plate 6.2. The top plate 6.1 has a through hole corresponding to the position of the exhaust pipe 4, and a fixing ring 6.4 is fixedly connected to its bottom surface. The outer diameter of the fixing ring 6.4 is the same as the diameter of the bottom plate 6.2. The opening of the filter bag 7 is fitted outside the fixing ring 6.4, and the filter bag 7 is installed outside the fixing ring 6.4 by a cable tie. A positioning rod 6.5 is fixedly connected between two adjacent vertical rods 6.3, and a circular plate 8 is rotatably installed outside the positioning rod 6.5.

[0025] The filter bag 7 is made of high temperature resistant material. During filtration, dust and other particulate impurities are retained on the outside of the filter bag 7. Air enters the inside of the support 6 after passing through the through holes on the surface of the filter bag 7, and then is discharged through the exhaust pipe 4.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the drive assembly includes a motor 15 mounted on one side of the top of the cover 2 and a pull rod 16 fixedly mounted on the top of the mounting base 12. The pull rod 16 extends above the cover 2. A cam 17 is mounted on the output shaft of the motor 15. A column 18 is provided on one side of the motor 15. A fixed shaft 19 is fixedly connected to the front end of the column 18. A horizontal plate 20 is rotatably mounted on the outside of the fixed shaft 19. A fixed frame 21 sleeved on the outside of the pull rod 16 is fixedly connected to one end of the horizontal plate 20. Both the horizontal plate 20 and the fixed frame 21 are provided with sliding grooves. A fixed rod 22 passing through the sliding groove is fixedly connected to the edge of the front end face of the cam 17. Limiting blocks 23 passing through the sliding groove are fixedly connected to the front and rear sides of the pull rod 16. A limiting cylinder sleeved on the outside of the pull rod 16 is fixedly connected to the bottom of the top plate 6.1.

[0027] Motor 15 drives cam 17 to rotate, cam 17 drives fixed rod 22 to rotate, so that fixed rod 22 slides in the groove on horizontal plate 20. Under the action of fixed shaft 19, horizontal plate 20 moves up and down reciprocally. According to the lever principle, fixed frame 21 also moves up and down reciprocally. Fixed frame 21 drives pull rod 16 to move up and down through limit block 23, causing mounting seat 12 to drive sleeve 13 to move up and down, causing horizontal bar 10 to drive circular plate 8 and connecting rod 9 to reciprocate around positioning rod 6.5. Connecting rod 9 drives beater plate 11 to rotate, realizing beating of filter bag 7, which can knock off dust on the surface of filter bag 7, thereby ensuring the filtration effect of filter bag 7.

[0028] In practical use, flue gas enters the treatment box 1 through the inlet pipe 3, is filtered by the filter bag 7, and is discharged through the exhaust pipe 4. The motor 15 drives the cam 17 to rotate, causing the pull rod 16 to move the mounting base 12 and the sleeve 13 up and down. This further causes the circular plate 8 and the connecting rod 9 to reciprocate around the positioning rod 6.5. The connecting rod 9 drives the beater plate 11 to rotate, which beats the filter bag 7, knocking off the dust on the surface of the filter bag 7, thus ensuring the filtration effect of the filter bag 7. The dust particles that are knocked off are discharged into the collection box 24 through the discharge pipe 5. When discharging, the valve on the discharge pipe 5 is closed and the sealing cover 25 is opened to discharge the dust.
