[0029] Please refer to Figure 5 The outer wall surface of dust removal equipment body 1 is fixedly installed with cylinder control center 20, and the lower wall surface of cylinder control center 20 is connected with two groups of first cylinder 21, and the connecting end of two groups of first cylinder 21 is fixedly installed with support frame 22, and the side of support frame 22 can be inserted into discharge outlet 3, and the upper wall surface of the side of support frame 22 is fixedly installed with limit plate 23.

[0030] Please refer to Figure 6 Two groups of second cylinder 24 are connected through the side wall surface of air induction bin 5, and the connecting end of two groups of second cylinder 24 is respectively fixedly installed with locking frame 25, and locking block 26 is respectively fixedly installed on two locking frames 25.

[0031] Please refer to Figure 7 Limit hole 27 is provided in the lower wall surface of filter screen 10, and is connected in the form of insertion with limit plate 23, two limit grooves 28 are provided in the side wall surface of filter screen 10, and are connected in the form of insertion with two locking blocks 26 respectively, and plug-in plate 33 for inserting limit hole 27 is fixedly installed on the upper wall surface of filter screen 10.

[0032] Referring to Figure 3 The upper wall surface of the transmission box 7 is provided with an empty slot 29 for the movement of the transmission plate 11, and the front wall surface of the transmission plate 11 is fixedly provided with a push plate 30 for pushing the filter screen 10 into the feeding guide opening 14.

[0033] Referring to Figure 2 The feeding box 6 is fixedly provided with an observation window 31 on both sides for observing the remaining amount of the filter screen 10, and in use, the operator first confirms whether there is remaining filter screen 10 in the feeding box 6 through the observation window 31 on both sides of the feeding box 6 to determine whether to feed.

[0034] Referring to Figure 2 The feeding box 6 is provided with a receiving slot 32 for receiving the transmission plate 11 during loading, and the transmission plate 11 is completely received in the receiving slot 32 in the feeding box 6, which can increase the feeding volume in the feeding box 6.

[0036] Specifically, the operator first confirms that there is no remaining filter screen 10 in the feeding box 6 through the observation window 31 on both sides of the feeding box 6, and then starts the motor 8, the output shaft of the motor 8 drives the lead screw 9 to rotate in the inner wall surface of the transmission box 7 through key connection; the lead screw 9 engages with the transmission plate 11 to drive the transmission plate 11 to move along the two light rods 12 towards the receiving slot 32 (the sliding seat 13 on the transmission plate 11 is in sliding cooperation with the light rod 12 to ensure smooth movement), until the transmission plate 11 is completely received in the receiving slot 32 in the feeding box 6, and the motor 8 is turned off; then, a plurality of filter screens 10 are neatly stacked and placed in the feeding box 6, ensuring that the limiting holes 27 of the filter screens 10 face downward and the limiting grooves 28 face the two sides;

[0037] The motor 8 is restarted, the motor 8 drives the lead screw 9 to rotate reversely, the transmission plate 11 moves along the lead screw 12 to the direction of the push block 17, the push plate 30 on the front wall surface of the transmission plate 11 synchronously pushes the stacked filter screen 10 to move to the lower side of the fixed frame 15; when the filter screen 10 at the frontmost position contacts the push block 17, the top of the filter screen 10 slides along the sliding inclined angle 19 of the connecting end of the push block 17, a downward pressure is generated to push the push block 17 to move upward, the push block 17 drives the two telescopic rods 16 to contract, and the reset spring 18 on the outer wall of the telescopic rod 16 is compressed; with the continuous pushing of the transmission plate 11, after the filter screen 10 completely passes the push block 17, reaches the upper side of the feeding guide opening 14, at this time, the pressure of the filter screen 10 on the push block 17 disappears, the reset spring 18 releases the elastic force to reset the telescopic rod 16, and the push block 17 moves downward to push the filter screen 10 into the feeding guide opening 14; the groove wall of the feeding guide opening 14 corrects the position of the filter screen 10, ensures that the center of the filter screen 10 is aligned with the center of the feeding port 2 of the dust removal equipment body 1, and the plug-in plate 33 on the upper wall surface of the filter screen 10 is accurately plugged into the limiting hole 27 of the filter screen 10 which has been installed below, to form preliminary positioning and prepare for subsequent locking and fixing.

[0039] Specifically, when the filter screen 10 is replaced, the dust removal equipment body 1 temporarily reduces the induced draft power; the operator sends an unlocking instruction through the cylinder control center 20, the cylinder control center 20 controls the two groups of second cylinders 24 to extend, the second cylinder 24 drives the locking frame 25 at the connecting end to move away from the filter screen 10, the locking block 26 on the locking frame 25 synchronously separates from the limiting groove 28 on the side wall of the old filter screen 10, and horizontal unlocking is completed; then the cylinder control center 20 controls the two groups of first cylinders 21 to extend, the first cylinder 21 drives the support frame 22 to slide downward along the discharging port 3, and under the action of gravity, the new filter screen 10 positioned in the feeding guide opening 14 and the old filter screen 10 in the induced draft chamber 5 synchronously slide downward along the discharging port 3, when the first cylinder 21 extends to the old filter screen 10 discharges from the dust removal equipment body 1, and the limiting groove 28 of the new filter screen 10 is aligned with the locking block 26, the first cylinder 21 stops extending, then the two groups of second cylinders 24 are controlled to contract, the locking frame 25 is driven to move to the direction of the new filter screen 10, the locking block 26 is re-plugged into the limiting groove 28 of the new filter screen 10, and horizontal limiting is completed; then the two groups of second cylinders 24 continue to fine-tune contraction, so that the upper wall of the new filter screen 10 is tightly attached to the inner wall of the induced draft chamber 5, the filter screen 10 is seamlessly attached to the inner wall of the equipment, the filtering sealing performance is improved, after the fixing is completed, the dust removal equipment body 1 restores the normal induced draft power, and the dust removal operation continues;

[0040] After the new filter screen 10 is fixed, the old filter screen 10 is suspended below the discharge port 3 with the support frame 22, the first air cylinder 21 is controlled by the air cylinder control center 20 to continue to extend until the plug-in plate 33 of the old filter screen 10 is separated from the limiting hole 27 of the new filter screen 10 (at this time, the new filter screen 10 is limited, and the discharge port 3 is blocked), and the operator manually takes down the old filter screen 10 from the limiting plate 23; after the old filter screen 10 is removed, the first air cylinder 21 is controlled to retract, and the support frame 22 is reset into the limiting hole 27 of the new filter screen 10 to standby, waiting for the next filter screen 10 replacement, and the whole old filter screen 10 removal process does not need to interrupt the dust removal operation of the new filter screen 10, and continuous dust removal is realized.

[0041] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
