AI Technical Summary
When using a pulse bag dust collector to remove waste slag generated during wood processing, it is difficult to clean up the dust at the bottom of the bag, resulting in the accumulation of dust and impurities, affecting the cleaning effect; at the same time, the bag is prone to clogging when filtering large-grain wood slag, affecting the normal circulation of gas.
A pulsed bag-type wood dust collector was designed. By turning on the motor, the rotating disc is rotated, driving the connecting rod and pull plate movement, causing the bag to shake and cooperate with the pulse jet of the jet pipe to clean the dust on the bag; at the same time, through the design of the filter plate and the inclined plate, the rubber head is used to knock on the fixing frame, so that large particles of debris fall into the lower hopper to avoid clogging.
It effectively avoids the accumulation of dust at the bottom of the bag and improves the cleaning effect; at the same time, it reduces the entry of large particles of debris into the bag, prevents blockage, and ensures the normal circulation of gas.

[0030] Combined Figure 1-6 As shown, the embodiments of the present disclosure provide a pulse bag type wood dust collector, including a box body 1. A fixing plate 14 is fixedly arranged inside the box body 1. A cloth bag 15 is installed inside the fixing plate 14. An installation plate 2 is fixedly arranged on one side of the box body 1. A first motor 21 is fixedly arranged at the bottom end of the installation plate 2. A turntable 22 is fixedly arranged at the output end of the first motor 21. A fixing rod 23 is fixedly arranged at the bottom end of the turntable 22. A connecting rod 24 is rotatably sleeved on the outer surface of the fixing rod 23. A moving plate 29 is slidably arranged inside the box body 1. The cloth bag 15 is installed inside the moving plate 29. Cross plates 28 are fixedly arranged on both sides of the moving plate 29. A pulling plate 26 is fixedly arranged on one side of one of the cross plates 28. A guiding rod 25 is fixedly arranged on the top surface of the pulling plate 26. One end of the connecting rod 24 away from the fixing rod 23 is rotatably arranged on the outer surface of the guiding rod 25. Limiting frames 27 are fixedly arranged on both sides of the box body 1. The cross plates 28 are slidably arranged inside the limiting frames 27. The number of the limiting frames 27 is two. The pulling plate 26 is movably arranged inside one of the limiting frames 27. By starting the first motor 21, the turntable 22 rotates, prompting both ends of the connecting rod 24 to rotate on the outer surfaces of the fixing rod 23 and the guiding rod 25 respectively, and making the pulling plate 26 slide inside one of the limiting frames 27. At the same time, the cross plates 28 drive the moving plate 29 to move left and right reciprocally, thereby making the cloth bag 15 vibrate, and cooperating with the pulse jet of the jet pipe 13, so as to be able to clean the dust and impurities attached to the cloth bag 15, avoid the accumulation of dust and impurities at the lower end of the cloth bag 15, and improve the cleaning effect of the cloth bag 15.
[0031] Optionally, a fixed frame 3 is fixedly arranged on one side of the box body 1. A conveying pipe 31 is fixedly arranged on one side of the fixed frame 3. An inclined plate 32 is fixedly arranged inside the fixed frame 3. A filter plate 33 is fixedly arranged inside the fixed frame 3. An auxiliary plate 34 is fixedly arranged on one side of the box body 1. An L-shaped plate 37 is slidably arranged above the auxiliary plate 34. A rubber head 38 is fixedly arranged on one side of the L-shaped plate 37. A chute 341 is formed inside the auxiliary plate 34. A slider 39 is fixedly arranged at the bottom end of the L-shaped plate 37. The slider 39 is slidably arranged inside the chute 341. A spring 343 is fixedly connected between the chute 341 and the slider 39. A sliding rod 342 is fixedly arranged inside the chute 341. The slider 39 is slidably sleeved on the outer surface of the sliding rod 342. A second motor 35 is installed on the top surface of the auxiliary plate 34. The output end of the second motor 35 is fixedly provided with a cam 36.
[0032] In this way, the gas and the debris in the wood processing process enter the fixed frame 3 together from the conveying pipe 31. Then, the large-particle debris is filtered by the filter plate 33 and falls onto the inclined plate 32. Then, the second motor 35 is started, so that the cam 36 rotates. When the cam 36 contacts the L-shaped plate 37, the L-shaped plate 37 is urged to drive the slider 39 to slide inside the chute 341 and compress the spring 343. When the cam 36 disengages from the L-shaped plate 37, the spring 343 resets, and the L-shaped plate 37 drives the rubber head 38 to strike the fixed frame 3, so that the large-particle debris on the filter plate 33 and the inclined plate 32 falls into the hopper 16. Furthermore, the wood debris in the gas can be pretreated, reducing the large-particle debris from entering the cloth bag 15 and causing the cloth bag 15 to be blocked, and improving the normal circulation of the gas.
[0033] Optionally, an exhaust pipe 17 is fixedly arranged on one side of the box body 1. A hopper 16 is fixedly arranged at the bottom end of the box body 1. A discharge box 4 is fixedly arranged at the bottom end of the hopper 16. A third motor 41 is installed on one side of the discharge box 4. The output end of the third motor 41 is fixedly provided with a spiral conveyor roller 42. A discharge port 43 is fixedly arranged at the bottom end of the discharge box 4.
[0034] In this way, the filtered gas can be discharged from the exhaust pipe 17. The dust and impurities falling through the hopper 16 fall into the discharge box 4. Then, the third motor 41 is started, so that the spiral conveyor roller 42 conveys the dust and impurities, and discharges from the discharge port 43, which is convenient for collecting them.
[0035] Optionally, a pulse inlet pipe 11 is fixedly arranged on one side of the box body 1. The outer surface of the pulse inlet pipe 11 is fixedly provided with equally spaced shunt pipes 12. The shunt pipes 12 are fixedly inserted into the box body 1. The outer surface of the shunt pipe 12 is fixedly provided with jet pipes 13.
[0036] In this way, a pulse device is externally connected to the pulse inlet pipe 11, so that the pulsed gas is transported from the shunt pipe 12 to the jet pipe 13 and then ejected from the jet pipe 13, thereby being able to clean the dust and impurities on the surface of the cloth bag 15.
[0037] Working principle: First, gas and debris in the wood processing process enter the fixed frame 3 together from the conveying pipe 31. Then, the large-particle debris is filtered by the filter plate 33 and falls onto the inclined plate 32. Then, the second motor 35 is turned on, causing the cam 36 to rotate. When the cam 36 contacts the L-shaped plate 37, the L-shaped plate 37 is prompted to drive the slider 39 to slide in the chute 341 and compress the spring 343. When the cam 36 disengages from the L-shaped plate 37, the spring 343 resets, and the L-shaped plate 37 drives the rubber head 38 to strike the fixed frame 3, so that the large-particle debris on the filter plate 33 and the inclined plate 32 falls into the feeding hopper 16, thereby being able to pre-treat the wood debris in the gas, reduce the large-particle debris from entering the cloth bag 15 and causing the cloth bag 15 to be blocked, improve the normal flow of the gas, and the filtered gas can be discharged from the exhaust pipe 17;
[0038] A pulse device is externally connected to the pulse inlet pipe 11, so that the pulsed gas is transported from the shunt pipe 12 to the jet pipe 13 and then ejected from the jet pipe 13, thereby being able to clean the dust and impurities on the surface of the cloth bag 15. By turning on the first motor 21, the turntable 22 rotates, prompting the two ends of the connecting rod 24 to rotate on the outer surfaces of the fixed rod 23 and the guide rod 25 respectively, and causing the pull plate 26 to slide in one of the limit frames 27. At the same time, the cross plate 28 drives the moving plate 29 to reciprocate left and right, thereby causing the cloth bag 15 to vibrate and cooperate with the pulsed jet of the jet pipe 13, so as to be able to clean the dust and impurities attached to the cloth bag 15, avoid the accumulation of dust and impurities at the lower end of the cloth bag 15, and improve the cleaning effect of the cloth bag 15;
[0039] The falling dust and impurities fall into the discharge box 4 through the feeding hopper 16. Then, the third motor 41 is turned on, so that the spiral conveying roller 42 conveys the dust and impurities and discharges them from the discharge port 43, thereby facilitating their collection.
