Description

Technical Field

[0001] The utility model belongs to the technical field of wood industry, and particularly relates to a bag dust collector for sawing edges of wood boards. Background Technique

[0002] A bag dust collector is a dry high-efficiency dust collector. It is a dust removal device that uses a bag-type filter element made of fiber fabric to capture solid particles in the dust-containing gas. Its working principle is that dust particles are intercepted by colliding with fibers due to inertial force when bypassing the filter cloth fibers. During wood industry production, it is necessary to saw the edges of wood boards. In order to prevent particles such as dust from floating in the air, a bag dust collector can be used for treatment.

[0003] The existing bag dust collector performs ash cleaning operations through the cooperation of the back blowing of a blower and a spray pipe. However, there is no mechanism for lifting the spray pipe during ash cleaning. The exhaust pipe is located above the filter bag and cannot be inserted into the filter bag. When the spray pipe sprays gas, a large amount of air flow will be lost above the filter bag (there is space above the filter bag for the cleaned air to flow), thus reducing the cleaning effect on the filter bag. Therefore, a technical measure is proposed to solve the problems in the prior art that there is no mechanism for lifting the spray pipe, the exhaust pipe is located above the filter bag and cannot be inserted into the filter bag, and a large amount of air flow will be lost above the filter bag when the spray pipe sprays gas, thus reducing the cleaning effect on the filter bag. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a bag dust collector for sawing edges of wood boards, aiming to solve the problems in the prior art that there is no mechanism for lifting the spray pipe, the exhaust pipe is located above the filter bag and cannot be inserted into the filter bag, and a large amount of air flow will be lost above the filter bag when the spray pipe sprays gas, thus reducing the cleaning effect on the filter bag.

[0005] To solve the above technical problems, the utility model provides such a bag dust collector for sawing edges of wood boards, which includes a tank body. The tank body converges towards the lower part. An installation plate is installed above the inner part of the tank body. A plurality of filter bags are threadedly and movably clamped in the installation plate. Through holes adapted to the filter bags are opened in the installation plate. A lifting ash cleaning assembly is arranged at the upper end of the side surface of the tank body. An air inlet pipe is installed at the lower end of the side surface of the tank body. Thanks to the setting of the lifting ash cleaning assembly, it is convenient to drive the spray pipe to insert into the inner wall of the filter bag, so that the air flow can completely enter the filter bag, preventing the air flow from being lost above the filter bag. The ash cleaning effect is good, the ash cleaning effect on the filter bag is improved, and the practicability is strong. Moreover, the lifting plate and the spray pipe can be hidden inside the tank cover, and it will not interfere with the replacement operation when replacing the filter bag.

[0006] Furthermore, the air inlet pipe is connected with a connecting pipe, and the other end of the connecting pipe is connected with a sawing edge mechanism.

[0007] Further, the tank body is threadedly and movably connected with a tank cover. A support frame is installed at the lower part of the tank body. At the upper end of the side surface of the end of the tank body far from the air inlet pipe, an exhaust pipe is installed. The exhaust pipe is connected with an external air conveying pipe, and an axial flow fan is installed on the external air conveying pipe.

[0008] Further, a dust discharge pipe is installed at the lower part of the tank body, and a draw plate is movably inserted into the dust discharge pipe.

[0009] Further, the lifting and dust cleaning assembly includes side plates. The side plates are fixedly installed at the upper part of one end of the tank body provided with the air inlet pipe. A fan is installed on the upper surface of the side plates. The fan penetrates through the tank body. The fan is connected with a flexible pipe. The flexible pipe is connected with a vertical pipe. The upper end of the vertical pipe is connected with a lifting plate, and the inside of the lifting plate is hollow.

[0010] Furthermore, a plurality of groups of air injection pipes are installed through the lower surface of the lifting plate. The air injection pipes are adapted to the inner wall of the filter bag. Two groups of symmetrically distributed abutting rods are installed on the upper surface of the lifting plate. The upper surface of the abutting rods is connected with a disc. Two groups of symmetrically distributed limiting blocks are installed at both ends of the disc. A screw rod is threadedly penetrated through the center position of the disc. The upper end of the screw rod is connected with a motor. The lower end of the motor is connected with a limiting column. The lower end of the limiting column is fixedly installed at the center position of the upper surface of the tank cover. The screw rod is rotationally connected with the limiting column.

[0011] Furthermore, two groups of symmetrically distributed limiting grooves are formed inside the limiting column. The limiting grooves are slidably adapted to the limiting blocks. Thanks to the cooperation of the limiting blocks and the limiting grooves, the disc is prevented from deflecting.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the setting of the lifting and dust cleaning assembly, the present utility model facilitates driving the air injection pipes to be inserted into the inner wall of the filter bag, so that the air flow can completely enter the filter bag, preventing the air flow from being dissipated above the filter bag. The dust cleaning effect is good, the dust cleaning effect on the filter bag is improved, the practicability is strong, and the lifting plate and the air injection pipes can be hidden inside the tank cover, which will not interfere with the replacement operation when replacing the filter bag.

The downward movement of the abutting rod drives the air injection pipe to move downward and be clamped into the inner wall of the filter bag. Start the fan to blow air into the inner wall of the filter bag to blow off the dust attached to the outside of the filter bag. After the dust cleaning is completed, turn off the fan and start the motor to reverse to drive the lifting plate back to the initial position. Description of the Drawings

Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] This detailed implementation manner is a sawing edge cloth bag dust collector for plates, and its structural schematic diagram is as shown in Figure 1 、 Figure 2As shown in the figure, it includes a tank body 3. The tank body 3 converges towards the lower part. Above the interior of the tank body 3, a mounting plate 10 is installed. A plurality of filter bags 11 are movably engaged in the internal thread of the mounting plate 10. Through holes adapted to the filter bags 11 are provided in the mounting plate 10. At the upper end of the side of the tank body 3, a lifting dust cleaning assembly 2 is provided. At the lower end of the side of the tank body 3, an air inlet pipe 12 is installed. The air inlet pipe 12 is connected to a connecting pipe 4. The other end of the connecting pipe 4 is connected to a sawing edge mechanism 1. The tank body 3 is threadedly and movably connected to a tank cover 9. At the lower part of the tank body 3, a support frame 5 is installed. At the upper end of the side of the end of the tank body 3 away from the air inlet pipe 12, an exhaust pipe 8 is installed. The exhaust pipe 8 is connected to an external air delivery pipe. An axial flow fan is installed on the external air delivery pipe. At the lower part of the tank body 3, a dust discharge pipe 6 is installed. A draw plate 7 is movably inserted into the dust discharge pipe 6. When actually sawing the edges of the plate, it can be collected symmetrically with respect to the tank body 3. Specifically, the plate is subjected to edge sawing operation through the sawing edge mechanism 1. The axial flow fan outside the exhaust pipe 8 is started. When the axial flow fan starts, dust and other particulate matters are drawn from the sawing edge mechanism 1 into the connecting pipe 4 and the tank body 3. Under the action of the filter bags 11 inside the tank body 3, the dust is blocked outside the filter bags 11, and the dust falls into the dust discharge pipe 6. When cleaning the dust in the existing situation, the draw plate 7 is pulled outwards, the dust falls, and the clean air passes through the filter bags 11 and enters the position between the mounting plate 10 and the tank cover 9, and then is discharged through the exhaust pipe 8 to complete the dust removal operation. When it is necessary to clean the filter bags 11, the lifting dust cleaning assembly 2 is used to clean the filter bags 11.

[0024] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown in the figure, the lifting and dust cleaning assembly 2 includes side plates 201. The side plates 201 are fixedly installed on the upper part of one end of the tank body 3 provided with the air inlet pipe 12. A blower 203 is installed on the upper surface of the side plates 201. The blower 203 penetrates through the tank body 3. The blower 203 is connected with a hose 202. The hose 202 is connected with a vertical pipe 204. The upper end of the vertical pipe 204 is connected with a lifting plate 205. The inside of the lifting plate 205 is hollow. A plurality of groups of air injection pipes 212 are installed through the lower surface of the lifting plate 205. The air injection pipes 212 are adapted to the inner wall of the filter bag 11. Two groups of symmetrically distributed abutting rods 211 are installed on the upper surface of the lifting plate 205. The upper surface of the abutting rods 211 is connected with a disc 208. Two groups of symmetrically distributed limit blocks 209 are installed at both ends of the disc 208. A screw rod 210 is threadedly penetrated through the center position of the disc 208. The upper end of the screw rod 210 is connected with a motor 207. The lower end of the motor 207 is connected with a limit post 206. The lower end of the limit post 206 is fixedly installed at the center position of the upper surface of the tank cover 9. The screw rod 210 is rotatably connected with the limit post 206. Two groups of symmetrically distributed limit grooves 213 are opened inside the limit post 206. The limit grooves 213 are slidably adapted to the limit blocks 209. Start the motor 207. The motor 207 drives the screw rod 210 to rotate when starting. The screw rod 210 rotates to drive the disc 208 to move downward along the limit groove 213. The disc 208 moves downward to drive the abutting rods 211 to move downward. The abutting rods 211 move downward to drive the lifting plate 205 to move downward. The lifting plate 205 moves downward to drive the air injection pipes 212 to move downward and be clamped into the inner wall of the filter bag 11. At this time, start the blower 203. The blower 203 blows air into the hose 202 when starting. Then the air enters the lifting plate 205 and the air injection pipes 212. Then the air enters the inner wall of the filter bag 11 to blow off the dust attached to the outside of the filter bag 11. After the dust cleaning is completed, turn off the blower 203 and start the motor 207 to reverse to drive the lifting plate 205 back to the initial position.

[0025] When actually sawing the edges of the plates, the collection can be carried out symmetrically with respect to the tank body 3. Specifically, the plates are subjected to edge sawing operations through the edge sawing mechanism 1. Start the axial flow fan (not shown in the figure) outside the exhaust pipe 8. The axial flow fan starts to draw dust and other particulate matters from the edge sawing mechanism 1 into the connecting pipe 4 and the tank body 3. Under the action of the filter bag 11 inside the tank body 3, the dust is blocked outside the filter bag 11. The dust falls into the ash discharge pipe 6. When cleaning the dust in the existing method, pull out the draw plate 7 outward, the dust falls, and the clean air enters the position between the mounting plate 10 and the tank cover 9 through the filter bag 11, and then is discharged through the exhaust pipe 8 to complete the dust removal operation.

[0026] When the filter bag 11 needs to be cleaned, the lifting and cleaning assembly 2 is used to clean the filter bag 11. Specifically, the motor 207 is started, and the motor 207 starts to drive the screw 210 to rotate. The rotation of the screw 210 drives the disc 208 to move downward along the limit groove 213 (the limit block 209 and the limit groove 213 are used in conjunction to prevent the disc 208 from deflecting). The disc 208 moves downward and drives the push rod 211 to move downward. The push rod 211 moves downward and drives the lifting plate 205 to move downward. The lifting plate 205 moves downward and drives the jet pipe 212 to move downward and get stuck in the inner wall of the filter bag 11 (a vertical pipe 204 is provided on the left side of the exhaust pipe 8, and the vertical pipe 204 is connected to the hose 202, as shown in FIG. Figure 5 As shown, there is a certain distance between the vertical pipe 204 and the jet pipe 212, and the hose 202 will not affect the jet pipe 212 when moving up and down). At this time, the fan 203 is started, and the fan 203 starts to blow air into the hose 202, and then the air enters the lifting plate 205 and the jet pipe 212, and then the air enters the inner wall of the filter bag 11 to blow off the dust attached to the outside of the filter bag 11. After the cleaning is completed, the fan 203 is turned off, and the motor 207 is started to reverse and drive the lifting plate 205 to return to the initial position. Through the setting of the lifting and cleaning component 2, it is convenient to drive the jet pipe 212 to insert into the inner wall of the filter bag 11, so that the airflow can completely enter the filter bag 11, and the airflow is prevented from being lost above the filter bag 11. The cleaning effect is good, the cleaning effect of the filter bag 11 is improved, and the practicability is strong. In addition, the jet pipe 212 can be hidden inside the tank cover 9, and when the filter bag 11 is replaced, it will not hinder the replacement operation.
