Description

Technical Field

[0001] The present invention relates to the technical field of dust removal filter bags, and in particular to a quick-detachable dust removal filter bag that is easy to maintain. Background Art

[0002] Dust filter bags are primarily used to remove dust from air. They typically consist of a cylindrical bag body made from polyester staple fibers, PPS fibers, PP polypropylene, aramid fibers, and nylon fibers. They typically have a service life of 2-4 years, offer excellent air permeability, a high dust collection rate, and are easy to clean, with a dust removal efficiency of up to 98.99%. While these bags are effective at removing PM2.5, traditional dust filter bags are relatively simple, featuring a simple cylindrical structure. As air passes through the bag, dust is filtered by the bag, and dust accumulates on the bag's surface, affecting the filtration effect.

[0003] In the existing technology, the frequency of replacement is high due to frequent clogging. At the same time, the traditional filter bag installation steps are cumbersome, and multiple sets of bolts need to be tightened at the bottom to ensure the bottom sealing and stability. The long downtime required for disassembly affects the air purification speed of the factory. At the same time, staying in a place full of smoke and dust will also have a great impact on the health of the maintenance personnel. In addition, the disassembly structure lacks a maintenance structure, and simple maintenance cannot be performed regularly, resulting in serious clogging and affecting work efficiency.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1 , Figure 1 It is a structural schematic diagram of the present invention.

[0026] A quick-detachable dust filter bag for easy maintenance, a quick-detachable dust filter bag for easy maintenance, comprises a mounting plate 1, a filter cage 2 arranged on the mounting plate 1 and a cloth bag 3 sleeved on the surface of the filter cage 2. Clamping grooves 4 are provided on both sides of the top of the mounting plate 1, and clamping blocks 5 that cooperate with the clamping grooves 4 are welded on both sides of the bottom of the filter cage 2. A sealing ring plate 6 is fixedly installed on the top of the clamping block 5, and the top of the sealing ring plate 6 is welded and fixed to the bottom of the filter cage 2. An anti-displacement component 7 is provided on the top of the clamping block 5 away from the filter cage 2. Maintenance grooves 8 are provided on both sides of the bottom of the mounting plate 1, and a maintenance mechanism 9 is provided inside the maintenance groove 8. A mounting groove 10 is provided on the top of the clamping groove 4, and a maintenance abutting plate 11 is slidably installed inside the mounting groove 10. A limit block 12 that slides with the mounting groove 10 is welded on the surface of the maintenance abutting plate 11. A locking groove 13 located on one side of the clamping groove 4 is provided on the top of the mounting plate 1, and an unlocking component 14 is provided inside the locking groove 13.

[0027] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , Figure 2 is a three-dimensional schematic diagram of the mounting plate of the present invention; Figure 3 It is a partially cutaway perspective schematic diagram of the mounting plate of the present invention; Figure 4 A half-cut perspective diagram of the mounting plate of the present invention; Figure 5 Schematic diagram of the top cross-sectional structure of the mounting plate of the present invention; Figure 6 for Figure 2A magnified view of middle A; Figure 7 for Figure 3 Enlarged view of middle B; Figure 8 for Figure 4 Enlarged view of C in the middle.

[0028] The anti-displacement assembly 7 includes a tightening groove 71, which is provided at the bottom of the clamping block 5 on a side away from the filter cage 2. A tightening block 72 is slidably mounted inside the tightening groove 71. A spring 73 is fixedly mounted at the bottom of the tightening block 72. A plug 74 is threadedly connected to the bottom of the inner wall of the tightening groove 71. The other end of the spring 73 contacts the top of the plug 74. The top of the tightening block 72 cooperates with the locking groove 13. The tightening groove 71 can be used to limit the sliding installation of the tightening block 72, so that the tightening block 72 is pressed against the locking groove 13 by the elastic force of the spring 73 to complete the positioning and prevent the clamping block 5 from being displaced after twisting. The plug 74 can also be used to limit the installation of the spring 73 to prevent the spring 73 and the tightening block 72 from falling downward, while facilitating the installation of the spring 73 and the tightening block 72.

[0029] The maintenance mechanism 9 includes a stepper motor 901, and the top of the stepper motor 901 is fixed to the top of the inner wall of the maintenance slot 8 by bolts. The output end of the stepper motor 901 is sleeved with a winding disk 902, and a winding rope 903 is wound around the surface of the winding disk 902. One end of the winding rope 903 is fixed to the winding disk 902, and the other end of the winding rope 903 is fixed to the maintenance clamping plate 11. A spring 2 904 is sleeved on the surface of the winding rope 903, and one end of the spring 2 904 contacts one side of the inner wall of the clamping slot 4, and the other end of the spring 2 904 contacts the maintenance clamping plate 11. After the stepper motor 901 is started, it can drive the winding disk 902 to rotate, and the winding rope 903 can be wound through the winding disk 902. The winding rope 903 can drive the maintenance clamping plate 11 to move to the side away from the clamping block 5, and at the same time, the elastic force of the spring 2 904 is contracted, and it can be contracted at a timed basis in conjunction with the external controller 21. Then, after reaching the limit position, the stepper motor 901 is turned off, so that the elastic force of the spring 2 904 is released, driving the maintenance clamping plate 11 to hit the clamping block 5, so that the clamping block 5 can be hit and the vibration can be transmitted to the sealing ring plate 6 to transmit vibration to the filter cage 2, thereby achieving the effect of vibrating the inner wall to remove part of the dust, thereby extending the filtration cycle.

[0030] The unlocking assembly 14 includes a threaded block 141, which is threadedly connected to the inner wall of the locking groove 13. A pressing pin 142 is slidably installed inside the threaded block 141. The cross-section of the pressing pin 142 is rectangular. A spring three 143 is sleeved on the surface of the pressing pin 142. One end of the spring three 143 contacts the top of the pressing pin 142, and the other end of the spring three 143 is fixedly connected to the top of the threaded block 141. After the threaded block 141 is rotated, the installation height of the pressing pin 142 is determined, and then the elastic force of the spring three 143 can facilitate the pressing pin 142 to reset after each pressing and use. When the bottom clamping block 72 needs to be pressed downward to unlock it, the pressing pin 142 is pressed downward to slide the clamping block 72 toward the bottom of the clamping groove 1 71, so that the clamping block 72 is separated from the locking groove 13, and then the elastic force of the spring two 904 can quickly bounce the clamping block 5 through the maintenance clamping plate 11 to the side of the inner wall of the clamping groove 4 away from the maintenance clamping plate 11, so that the maintenance person can pull up and remove the dust filter bag.

[0031] A rubber adapter block 15 is fixedly mounted on the bottom of the sealing ring plate 6. A torsion shaft 16 is welded to both sides of the top of the sealing ring plate 6. A rubber pad is fixedly mounted on the side of the maintenance abutment plate 11 near the clamping block 5. The rubber adapter block 15 eliminates the installation gap between the sealing ring plate 6 and the mounting plate 1, achieving a sealing effect. The torsion shaft 16 also facilitates maintenance personnel to twist the sealing ring plate 6 for installation. The rubber pad also cushions some rigid impact damage, preventing surface damage from impacts on the maintenance abutment plate 11.

[0032] Anti-separation blocks 17 are fixedly mounted on both sides of the abutting block 72. The anti-separation blocks 17 slide in engagement with the inner wall of the abutting groove 1 71. The anti-separation blocks 17 prevent the abutting block 72 from popping up to its limit position, ensuring that the limit height is not too high. This prevents the sealing ring plate 6 from pressing the clamping block 5 downward via the elastic rubber adapter block 15, thereby ensuring the abutting height of the abutting block 72, and facilitating the abutting block 72 to enter the locking groove 13 for positioning after twisting.

[0033] A spring receiving groove 18 is defined on the inner wall of the engaging groove 4, on the side away from the maintenance abutment plate 11. This groove cooperates with the second spring 904. A second plug 19 is threadedly connected to the bottom of the inner wall of the maintenance groove 8. The spring receiving groove 18 accommodates the second spring 904, ensuring that, when retracted to its limit, it does not affect the sliding movement of the maintenance abutment plate 11 to its limit retracted position. Furthermore, the second plug 19 protects the stepping motor 901 within the maintenance groove 8.

[0034] Both the first and second plugs 74 and 19 have hexagonal sockets 20 at their bases. A controller 21 is located on the top side of the mounting plate 1. The controller 21 houses a time relay, which is electrically connected to the stepper motor 901 via a wire. The hexagonal sockets 20 allow maintenance personnel to conveniently install the first and second plugs 74 and 19 using a hexagonal wrench. The controller 21 also allows for automated control of the stepper motor 901's opening and closing, simplifying maintenance operations.

[0035] Working principle: Maintenance personnel preset a time to start stepper motor 901 for simple maintenance through controller 21, and start stepper motor 901 regularly through built-in time relay. After stepper motor 901 starts, it drives take-up disk 902 to rotate, and take-up rope 903 can be wound through take-up disk 902. Take-up rope 903 can drive maintenance clamping plate 11 to move to the side away from clamping block 5, and at the same time, make spring 2 904 elastic force contract, and can contract regularly in conjunction with external controller 21, and then turn off stepper motor 901 after reaching the limit position, so that spring 2 904 elastic force is released, drives maintenance clamping plate 11 to hit clamping block 5, so that clamping block 5 can be transmitted to sealing ring plate 6 after being hit to vibrate filter cage 2, so as to remove part of dust by vibration of inner wall, and extend the filter use cycle. The above vibration operation presets the number of vibration operation through controller 21 to ensure maintenance effect, and bag 3 is blocked. When bottle cap 7 is in the state of being blocked, just can directly push away from bottle cap 71, thus makes bottle cap 71 be in the state of being blocked.
