Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0026] Please refer to Figures 1 to 6 In the embodiment, the environment-friendly dust removal equipment facilitating replacement of filter assemblies comprises a dust removal box 1, gas outlet pipes 2 and gas inlet pipes 3 fixedly connected to the left and right sides of the dust removal box 1 respectively, and a filter screen plate 4 detachably installed in the dust removal box 1, the outside of the dust removal box 1 is provided with a replacement mechanism 5 for quick replacement of the filter screen plate 4, and the outside of the dust removal box 1 is provided with a dust collection mechanism 6 extending into the dust removal box 1 for real-time adsorption of falling dust.

[0027] The replacement mechanism 5 comprises a mounting box 51 fixedly connected to the outside of the dust removal box 1, a reciprocating screw rod 52 rotatably connected to the inside of the mounting box 51, a moving block 53 threadedly connected to the outside of the reciprocating screw rod 52, a drive rod 54 fixedly connected to the top of the moving block 53, a mounting frame 55 fixedly connected to the left end of the drive rod 54, and a transmission mechanism arranged on the outside of the mounting box 51.

[0028] Specifically, the transmission mechanism comprises a drive motor 56 fixedly installed on the outside of the mounting box 51, a transmission gear 57 fixedly connected to the output shaft of the drive motor 56, and a driven gear 58 fixedly installed on the outside of the reciprocating screw rod 52, and the transmission gear 57 and the driven gear 58 are in meshing engagement. The reciprocating screw rod 52 is rotatably connected to the inside of the mounting box 51 and extends to the outside thereof, a transmission opening adapted to the drive rod 54 is formed in the inside of the dust removal box 1, a sealing gasket adapted to the drive rod 54 is fixedly installed in the inside of the transmission opening, a sliding block extending to the inside of the mounting box 51 is fixedly connected to the bottom of the moving block 53, a sliding groove adapted to the sliding block is formed in the inside of the mounting box 51, and the sliding block and the sliding groove are in sliding connection.

[0029] It shall be noted that the top of the mounting frame 55 is provided with a locking structure for limiting the filter screen plate 4, which comprises a limiting seat 59 fixedly connected to the top of the mounting frame 55 and a locking screw rod 510 rotatably connected to the upper surface of the limiting seat 59 and abutting against the top of the filter screen plate 4. The driving motor 56 is started to rotate by the controller, and the output shaft drives the transmission gear 57 to rotate, which drives the driven gear 58 to rotate, and further drives the reciprocating lead screw 52 to rotate inside the mounting box 51. The moving block 53 moves linearly along the reciprocating lead screw 52 under the sliding limiting action of the sliding block and the sliding groove, and the driving rod 54 moves to drive the mounting frame 55 to slide inside the sliding seat 511. At the same time, the driving rod 54 moves in the transmission port, and the sealing gasket in the transmission port ensures the sealing. When the mounting frame 55 moves to the moving port, the mounting frame 55 automatically pushes open the shielding plate 7, and the mounting frame 55 can be pushed out of the moving port. The locking screw rod 510 is manually rotated to release the limitation of the filter screen plate 4. The old filter screen plate 4 is taken out, and the new filter screen plate 4 is put in. The locking screw rod 510 is tightened to fix it. Then the mounting frame 55 is pushed back into the dust removal box 1 to complete the replacement of the filter screen plate 4.

[0030] In addition, the dust removal box 1 is fixedly provided with a sliding seat 511 matched with the mounting frame 55, and the mounting frame 55 is slidingly connected to the inside of the sliding seat 511. The dust removal box 1 is provided with a moving port matched with the mounting frame 55 and the filter screen plate 4, and the shielding plate 7 is rotatably installed outside the moving port. The shielding plate 7 rotatably installed outside the moving port is provided with torsion springs at both ends, which cooperate with the movement of the mounting frame 55 to automatically open when the filter screen plate 4 is replaced, and automatically reset the shielding moving port after the replacement is completed, which facilitates the replacement of the filter screen plate 4 and ensures the sealing of the equipment.

[0031] In the embodiment, the dust collecting mechanism 6 comprises a box body 61 fixedly connected to the outside of the dust removal box 1, a mounting pipe 62 fixedly installed on the inner wall of the dust removal box 1, a suction nozzle 63 fixedly communicated outside the mounting pipe 62, a centrifugal fan 64 rotatably installed outside the box body 61, a connecting pipe 68 fixedly communicated between the box body 61 and the mounting pipe 62, and a synchronous structure provided outside the centrifugal fan 64.

[0032] The synchronous structure comprises a driven wheel 65 fixedly installed outside the centrifugal fan 64, a transmission wheel 66 fixedly connected to the left end of the reciprocating lead screw 52, and a belt 67 drivingly connected to the transmission wheel 66 and the driven wheel 65 outside. The reciprocating lead screw 52 and the centrifugal fan 64 rotate synchronously through the belt 67. When the reciprocating lead screw 52 rotates, the transmission wheel 66 at the left end drives the driven wheel 65 to rotate through the belt 67, thereby driving the centrifugal fan 64 to operate. The operation of the centrifugal fan 64 forms a negative pressure inside the box body 61, and the suction nozzles 63 generate suction through the connecting pipes 68 and the mounting pipes 62. The dust falling off the surface of the filter screen 4 is sucked into the suction nozzles 63, and then enters the box body 61 through the mounting pipes 62 and the connecting pipes 68. The dust entering the box body 61 falls into the collecting frame 69. When the collecting frame 69 is full of dust, the collecting frame 69 can be taken out through the taking opening for cleaning. The replacement of the filter screen 4 and the collection of dust are linked, the equipment cost and energy consumption are reduced, and the dust falling off the surface of the filter screen 4 can be sucked in real time, so that the inside of the dust removal box 1 is kept clean, and the dust removal effect and service life of the equipment are improved.

[0033] Specifically, the number of the suction nozzles 63 is several, the several suction nozzles 63 are distributed at equal intervals on the outside of the mounting pipes 62 in sequence, and are located at the top of the filter screen 4. The inside of the box body 61 is slidably connected with the collecting frame 69, and the inside of the box body 61 is provided with a taking opening matched with the collecting frame 69.

[0034] The working principle of the above embodiment is as follows:

[0035] In use, the dust-containing gas enters the dust removal box 1 from the air inlet pipe 3, and the dust is intercepted by the filter screen 4. The clean gas is discharged from the air outlet pipe 2, and the preliminary dust removal is completed. The controller is started to drive the driving motor 56 to operate, and the output shaft drives the transmission gear 57 to rotate. The transmission gear 57 is engaged with the driven gear 58, thereby driving the driven gear 58 and the reciprocating lead screw 52 to rotate in the mounting box 51. The reciprocating lead screw 52 rotates to make the moving block 53 move linearly under the limitation of the bottom sliding block and the sliding slot of the mounting box 51, thereby driving the top driving rod 54 to move in the transmission opening. The installation frame 55 moves to push away the shielding plate 7. The old filter screen 4 is taken out by manually rotating the locking screw 510, the new filter screen 4 is put in and the locking screw 510 is tightened for fixation. The driving motor 56 operates to push back the installation frame 55, and the shielding plate 7 is reset to shield the moving opening. The transmission wheel 66 at the left end of the reciprocating lead screw 52 drives the driven wheel 65 and the centrifugal fan 64 to operate through the belt 67. The centrifugal fan 64 forms a negative pressure inside the box body 61, and the suction nozzles 63 generate suction through the connecting pipes 68 and the mounting pipes 62. The dust falling off the surface of the filter screen 4 is sucked into the box body 61 through the suction nozzles 63, the mounting pipes 62 and the connecting pipes 68. The dust falls into the collecting frame 69 in the box body 61, and the collecting frame 69 can be taken out from the taking opening for cleaning.

[0036] The mounting mode, the connecting mode or the setting mode disclosed in the embodiment are all common mechanical connecting modes, and can be implemented as long as the beneficial effects can be achieved. In addition, the electrical components appearing in the embodiment are electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. A person skilled in the art can realize the control of the electrical components through simple programming. The existing disclosed power connection technology also belongs to the common knowledge in the field. Therefore, the specific structure composition and working principle of the embodiment will not be described in more details.
