Description

Technical Field

[0001] The invention relates to the technical field of pneumatic conveying, in particular to an environmentally friendly pneumatic conveying mechanism with anti-clogging and dust removal functions. Background Art

[0002] Pneumatic conveying uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipe. During the operation of the Roots blower, external air is drawn into the air pipe, thereby driving the flow of materials. In order to prevent impurities in the air from entering the air pipe and causing blockage, the impurities in the air need to be filtered.

[0003] During the operation of the Roots blower, the filter cleans the impurities in the air, but the impurities will clog the filter, reducing the amount of air entering the Roots blower, thereby reducing the air flow rate inside the air pipe, making it inconvenient to pneumatically convey the material. Currently, the filter is generally removed manually for cleaning, but the pneumatic conveying mechanism needs to stop working during manual disassembly, which not only increases the workload, but also reduces the working efficiency of the pneumatic conveying mechanism.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides an environmentally friendly pneumatic conveying mechanism with anti-clogging and dust removal functions, which has the following beneficial effects:

[0018] 1. The cam pushes rack 1 to move, which in turn drives the gear to rotate, and then pushes the push rod to move to clean the filter. The drive motor drives the cam to move actively. The rotation of the cam squeezes the L-shaped rod, causing the L-shaped rod to move upward. The upward movement of the L-shaped rod drives rack 1 to move, and then drives the gear to rotate. The rotation of the gear drives rack 2 to move. The movement of rack 2 drives the push rod through the connecting rod. The push rod moves to clean the impurities on the filter.

[0019] 2. The push rod moves and squeezes the triangular block to make the rotating plate rotate and unfold, thereby facilitating the discharge of impurities. The push rod pushes the impurities to move to one of the rotating plates. The push rod continues to move to squeeze the triangular block, so that the triangular block moves downward. The downward movement of the triangular block drives the rotating plate and the connecting block to rotate around the fixed pin. The rotating plate rotates in an inclined state, and at the same time, the square through hole is opened, and the cleaned impurities slide through the rotating plate to the outside of the hollow shell.

[0020] 3. The elastic force of spring 1 facilitates the reverse movement of the L-shaped rod, thereby driving the push rod to move in the reverse direction to clean the filter. After the cam rotates 180°, the cam continues to rotate and separates from the L-shaped rod. Under the action of the elastic force of spring 1, the L-shaped rod moves downward, and rack 1 moves downward, thereby causing the gear to rotate in the reverse direction. The reverse rotation of the gear drives rack 2 to move, and the movement of rack 2 drives the push rod to move in the reverse direction to clean the filter again.

[0021] 4. Move the square block to squeeze the inclined surface block, so that the T-block moves and fits with the strip rod, install the square frame inside the sound insulation cover, and drive the square block to move during the installation of the square frame. The movement of the square block squeezes the inclined surface block through the inclined surface, so that the inclined surface block moves. During the movement of the inclined surface block, the T-block is driven to move along the square groove and fit with the strip rod, and then the T-block is clamped inside the square groove to achieve the installation of the sound insulation cover.

[0022] 5. The sponge pad is installed by rotating the rotating block in the opposite direction to fit it with the square frame. When one end of the square frame fits with the limit block, one end of the square frame is flush with one end of the sound insulation cover. The rotating block is rotated in the opposite direction to separate from the magnetic block. Under the action of the torsion force of the torsion spring, the rotating pin drives the rotating block to rotate and reset to fit with the limit frame, thereby completing the installation of the sponge pad.

[0035] In particular, a square frame 27 is movably installed at one end of the soundproof cover 8, and a sponge pad 28 is fixedly installed inside the square frame 27. The design of the sponge pad 28 can not only play a role in sound insulation, but also dissipate the heat inside the soundproof cover 8. A block 30 is installed at the middle position of the rear end of the square frame 27 by screws, and the bottom end of the block 30 is fitted with the bottom plate 1. Two limit blocks 29 are symmetrically welded at the top end of the soundproof cover 8, and the limit blocks 29 are fitted with the square frame 27.

Two magnetic blocks 40 are symmetrically installed on the sound insulation cover 8 by screws. The design of the magnetic block 40 facilitates the adsorption and fixation of the rotating block 38.

[0036] The working principle of this embodiment is as follows: when the filter screen 20 needs to be cleaned, the driving motor 2 works to drive the Roots motor to work through the pulley and the belt, and at the same time, the driving motor 2 works to drive the cam 11 actively, and the cam 11 rotates to squeeze the L-shaped rod 12, so that the L-shaped rod 12 moves upward, and the L-shaped rod 12 moves upward to drive the rack 15 to move, thereby pushing the gear 41 to rotate, and the gear 41 rotates while driving the rack 2 17 to move, and the rack 2 17 moves through the connecting rod 18 to drive the push rod 19 to move, and the push rod 19 moves to clean the impurities on the filter screen 20, and the push rod 19 pushes the impurities to move to one of the rotating plates 22, and the push rod 19 continues to move to squeeze the triangular block 23, so that the triangular block 23 moves downward, and the triangular block 23 moves downward to drive the rotating plate 22 and the connecting block 26 to rotate around the fixed pin 25, and at the same time squeezes the torsion spring 2, so that the torsion spring 2 generates a torsion force, and the torsion force of the torsion spring 2 facilitates the rotation and reset of the rotating plate 22 to block the square through hole, and the rotating plate 22 rotates in an inclined state, and at the same time makes the square through hole The cleaned impurities slide to the outside of the hollow shell 21 through the rotating plate 22, and the fixing ring 13 moves upward during the upward movement of the L-shaped rod 12. The fixing ring 13 moves upward to stretch the spring 14, so that the spring 14 generates elastic force. When the cam 11 rotates 180°, the cam 11 continues to rotate and separates from the L-shaped rod 12. Under the action of the elastic force of the spring 14, the L-shaped rod 12 moves downward, and the rack 15 moves downward, thereby causing the gear 41 to rotate in the opposite direction. The gear 41 rotates in the opposite direction and drives the rack 17 The push rod 19 moves, and the rack 17 moves to drive the push rod 19 to move in the opposite direction to clean the filter 20 again, and push the impurities on the filter 20 to the inside of another hollow shell 21. The push rod 19 squeezes the triangular block 23 on the other rotating plate 22, so that the other rotating plate 22 rotates and opens to discharge the impurities. The driving motor 2 continuously drives the cam 11 to rotate during operation, so that the push rod 19 repeatedly cleans the filter 20 to avoid impurities blocking the filter 20 and causing insufficient air intake.

[0037] When the sponge pad 28 needs to be installed, first rotate the rotating block 38 around the rotating pin 37. The rotation of the rotating block 38 drives the rotating pin 37 to rotate. The rotation of the rotating pin 37 squeezes the torsion spring 2, so that the torsion spring 2 generates torque. The rotating block 38 rotates and is adsorbed and fitted with the magnetic block 40. The adsorption force between the magnetic block 40 and the rotating block 38 is greater than the torsion of the torsion spring 2, thereby fixing the position of the rotating block 38. The sound insulation cover 8 is installed on the base plate 1, and the air intake pipe 9 is plugged into the Roots blower 3. The T-block 32 is correspondingly inserted into the square groove, and then the square frame 27 is installed in the sound insulation cover 8. During the installation of the square frame 27, the block 30 is driven to move. The block 30 moves and squeezes the inclined surface block 31 through the inclined surface, so that the inclined surface block 31 moves. During the movement of the inclined plane block 31, the T-block 32 is driven to move along the square groove and fit with the strip rod 33, and then the T-block 32 is clamped inside the square groove to realize the installation of the sound insulation cover 8. When the inclined plane block 31 moves, the slider 35 is driven to move along the guide rod 34. The slider 35 moves to squeeze the spring 2 36, so that the spring 2 36 generates an elastic force. The elastic force of the spring 2 36 facilitates the movement and reset of the inclined plane block 31. When one end of the square frame 27 fits with the limit block 29, one end of the square frame 27 is flush with one end of the sound insulation cover 8, and the rotating block 38 is rotated in the opposite direction. The rotating block 38 rotates and separates from the magnetic block 40. Under the action of the torsion of the torsion spring 1 39, the rotating pin 37 drives the rotating block 38 to rotate and reset to fit with the limit frame, thereby completing the installation of the sponge pad 28.
