Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a multi-stage dust collection device for wood processing. Background Technology

[0002] During the wood processing process, a large amount of sawdust and dust are generated. In order to avoid harming the health of users, dust collection devices need to be installed in dust-rich areas to collect the generated dust. However, when the current dust collection equipment is in use, as dust continues to enter, it is easy for the dust to block the air inlet, thereby reducing the dust collection capacity of the device. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where dust can easily clog the air inlet holes as dust continues to enter, thereby reducing the dust collection capacity of the device. Therefore, this invention proposes a multi-stage dust collection device for wood processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a multi-stage dust collection device for wood processing, including an air cylinder and a reciprocating cleaning assembly. The reciprocating cleaning assembly includes a straight pipe that is connected to the air cylinder. An air outlet pipe is connected to the side of the straight pipe. A piston is slidably connected inside the straight pipe. A U-shaped tube is fixedly connected to the surface of the piston. A reciprocating plate is fixedly connected to the end of the U-shaped tube. A fixing frame is fixedly connected to the periphery of the air cylinder. A spring is fixedly connected between the fixing frame and the reciprocating plate. A separation cover is fixedly connected to the bottom of the air cylinder.

[0006] Preferably, an L-shaped rod is fixedly connected to the bottom surface of the reciprocating plate, a disc is fixedly connected to the end of the L-shaped rod, a plurality of hinge rods are symmetrically hinged on the disc, a rotating sleeve is rotatably connected to the bottom surface of the separation cover, and the other end of the hinge rod is hinged to the rotating sleeve.

[0007] Preferably, a plurality of cleaning plates are fixedly connected inside the rotating sleeve, and a plurality of bristles are evenly fixedly connected to one side of the cleaning plate near the separation cover, the bristles abutting against the separation cover.

[0008] Preferably, an air intake assembly is fixedly connected to the surface of the air cylinder. The air intake assembly includes a motor, which is fixedly connected to the air cylinder. A rotating shaft is fixedly connected to the output end of the motor, and a turbine is fixedly connected to the end of the rotating shaft.

[0009] Preferably, the turbine, air cylinder, and separator all have the same axis.

[0010] Preferably, a partition is fixedly connected to the periphery of the air cylinder, and an interception net is fixedly connected inside the partition, with the interception net located at the bottom of the disc.

[0011] Preferably, the mesh size of the interceptor net is larger than the aperture of the separation cover.

[0012] Preferably, the bottom of the partition is open, and the partition is truncated cone-shaped.

[0013] The present invention discloses a multi-stage dust collection device for wood processing, which has the following advantages: When in use, the turbine rotates to create negative pressure, which draws external dust into the device. The dust is then separated by a separation hood. At this time, air continuously enters the straight pipe, increasing the air pressure inside the straight pipe. This causes the tension spring to push the piston upward. After depressurization, the piston returns to its original position. As the device continues to operate, the piston drives the reciprocating plate to move up and down continuously, continuously cleaning the dust adhering to the separation hood and preventing excessive dust accumulation on the separation hood, which would reduce the dust collection capacity of the device.

[0021] 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. Example

[0022] Reference Figure 1-5This utility model is a multi-stage dust collection device for wood processing, including an air cylinder 1 and a reciprocating cleaning assembly. The reciprocating cleaning assembly includes a straight pipe 5, which is connected to the air cylinder 1. An air outlet pipe 6 is connected to the side of the straight pipe 5. A piston 7 is slidably connected inside the straight pipe 5. A U-shaped tube is fixedly connected to the surface of the piston 7. A reciprocating plate 10 is fixedly connected to the end of the U-shaped tube. A fixing frame 9 is fixedly connected to the periphery of the air cylinder 1. A spring 11 is fixedly connected between the fixing frame 9 and the reciprocating plate 10. A separation cover 4 is fixedly connected to the bottom surface of the air cylinder 1.

[0023] The operation process of this embodiment is as follows: the device is placed at the dust accumulation position of wood processing, a negative pressure is formed in the air cylinder 1, and the dust from the outside is gathered towards the separation hood 4. The dust from the outside moves towards the separation hood 4 through the clean air. The dust is blocked by the holes on the separation hood 4, and the clean air is discharged through the straight pipe 5 through the air cylinder 1. In this way, the dust in the air can be separated and accumulated at the bottom of the separation hood 4, thus completing the dust collection of wood processing.

[0024] Air continuously enters the straight pipe 5. In the initial state, the spring 11 pulls the piston 7 to the bottom of the outlet pipe 6. At this time, as air continues to enter, the air pressure in the straight pipe 5 increases, and the air pushes the piston 7 to move upward until the piston 7 passes the position of the outlet pipe 6. After the clean gas is discharged through the outlet pipe 6, the air pressure in the straight pipe 5 returns to normal, and the spring 11 pulls the piston 7 back to its original position. That is, when air is continuously supplied into the straight pipe 5, it can drive the piston 7 to move back and forth.

[0025] The reciprocating movement of piston 7 drives U-shaped rod 8 to move up and down on fixed frame 9, thereby driving reciprocating plate 10 to move up and down to brush away the dust accumulated on separation cover 4, thus preventing dust from continuously accumulating on separation cover 4 and clogging the holes on separation cover 4. Example

[0026] Simply moving the reciprocating plate 10 up and down is not very effective at cleaning dust adhering to the separation cover 4. Therefore, please refer to... Figure 4-5 Based on the first specific embodiment, an L-shaped rod 12 is fixedly connected to the bottom surface of the reciprocating plate 10, and a disc 13 is fixedly connected to the end of the L-shaped rod 12. Several hinge rods 15 are symmetrically hinged on the disc 13. A rotating sleeve 14 is rotatably connected to the bottom surface of the separation cover 4. The other end of the hinge rod 15 is hinged to the rotating sleeve 14. Several cleaning plates are fixedly connected inside the rotating sleeve 14. Several bristles 16 are evenly fixedly connected to the side of the cleaning plate near the separation cover 4. The bristles 16 abut against the separation cover 4.

[0027] The operation process of this embodiment is as follows: the reciprocating plate 10 moves up and down, driving the L-shaped rod 12 and the disc 13 to move up and down reciprocally. Due to the rotational engagement between the rotating sleeve 14 and the separation cover 4, when the disc 13 moves up and down reciprocally, it drives the hinge rod 15 on the disc 13 to move. Multiple hinge rods 15 reciprocate to push the rotating sleeve 14 to rotate back and forth on the separation cover 4. The bristles 16 always remain in contact with the separation cover 4. At this time, because the rotating sleeve 14 rotates back and forth, that is, the bristles 16 rotate back and forth continuously on the separation cover 4, the cleaning effect of the dust stuck on the separation cover 4 can be improved. Example

[0028] When dust is collected only once through separation hood 4, it is difficult to separate sawdust from dust, and sawdust easily clogs separation hood 4. Therefore, please refer to [the relevant documentation / reference needed]. Figure 1-2 Based on the first specific embodiment, an air intake assembly is fixedly connected to the surface of the air cylinder 1. The air intake assembly includes a motor, which is fixedly connected to the air cylinder 1. A rotating shaft 2 is fixedly connected to the output end of the motor, and a turbine 3 is fixedly connected to the end of the rotating shaft 2. The turbine 3, the air cylinder 1, and the separation cover 4 all have the same axis. A partition 17 is fixedly connected to the periphery of the air cylinder 1. An interception net 18 is fixedly connected inside the partition 17. The interception net 18 is located at the bottom of the disc 13. The mesh size of the interception net 18 is larger than the aperture of the separation cover 4. The bottom of the partition 17 is open, and the partition 17 is truncated cone-shaped.

[0029] The operation process of this embodiment is as follows: the mixture of wood chips and dust enters the hopper 17, and the intercepting net 18 blocks the wood chips so that they do not enter the hopper 17. At this time, after the dust and air enter the hopper 17, the dust is blocked by the separation cover 4, thereby performing multi-stage dust collection during wood processing and preventing wood chips from blocking the holes on the separation cover 4.

[0030] When in use, the motor drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the turbine 3 to rotate. The rotation of the turbine 3 causes the air to move towards the position of the straight pipe 5 through the interception net 18 and the separation cover 4, which can keep the outside air evenly input into the air cylinder 1, so as to continuously carry out dust collection operations.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
