[0001] This utility model relates to the field of dust removal equipment technology, specifically a dust removal equipment with an easy-to-replace filter element structure. Background Technology

[0002] Dust removal equipment refers to equipment that separates dust from flue gas; it is also called a dust collector or dust removal device.

[0003] In existing technology, dust removal equipment uses filter elements for filtration. The filter elements are usually installed inside the dust removal equipment by fixing them with multiple sets of bolts. Their function is to trap dust contained in the air drawn in by the fan, thereby purifying the dusty gas.

[0004] However, the traditional method of fixing the filter element in the dust removal equipment with multiple sets of bolts is inconvenient to operate, and the filter element needs to be disassembled for maintenance and cleaning, which takes a long time and is not conducive to improving efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal device that facilitates the replacement of filter elements, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device that facilitates filter element replacement, the dust removal device comprising:

[0007] The dust collector body is provided with a limiting seat on its surface, and a slot is provided on the surface of the limiting seat. A filter element is provided above the limiting seat.

[0008] The lower limit ring has a retaining plate and a limiting post on its surface, and a spring and a limiting cylinder are fitted on the limiting post. Preferably, a partition is fixed in the upper middle part of the dust collector body, and several upper limit rings are symmetrically fixed on the bottom surface of the partition. The upper limit rings are ring-shaped.

[0009] Preferably, the limiting seat is fixed on the inner bottom surface of the dust collector body. There are several limiting seats, which are symmetrically distributed, and the limiting seats correspond to several upper limiting rings.

[0010] Preferably, the card slot is L-shaped, and there are two sets of card slots. The two sets of card slots are distributed in opposite directions, and one end of the card slot penetrates the top surface of the limiting seat.

[0011] Preferably, the lower limit ring is located inside the dust collector body, and there are several lower limit rings. The number of lower limit rings and the number of limit seats are equal and correspond to each other. There are two sets of clamping plates, and the two sets of clamping plates are symmetrically fixed on both sides of the top surface of the lower limit ring.

[0012] Preferably, the limiting post is fixed to the bottom surface of the lower limiting ring, the bottom end of the limiting cylinder is fixed to the inner bottom surface of the dust collector body, the limiting cylinder is located inside the spring, the upper end of the spring abuts against the bottom surface of the lower limiting ring, and the lower end of the spring abuts against the inner bottom surface of the dust collector body, and the locking plate and the locking groove are compatible. Preferably, the upper end of the filter element is located in the upper limiting ring, and the lower end of the filter element is located in the lower limiting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a dust removal device that facilitates filter element replacement. During filter element installation, the filter element is placed inside the dust collector body, with its bottom positioned within the lower limit ring. The lower limit ring is then rotated using a clamping plate, moving the clamping plate to the opening of the slot. The clamping plate is then slowly loosened, causing the lower limit ring to move upwards under the elastic support of a spring. During this movement, the lower limit ring supports the filter element upwards. When the top of the filter element is inserted into the upper limit ring, the filter element is installed and fixed. During filter element removal, the lower limit ring is moved downwards by pressing the clamping plate, disengaging the top of the filter element from the upper limit ring and releasing its restriction. The clamping plate is then adjusted to the opening of the slot, and rotated to move it into the slot, limiting the lower limit ring and preventing it from moving upwards. The filter element can then be removed from the lower limit ring. This design improves the ease of operation when disassembling the filter element for maintenance and cleaning, making it simpler and more efficient than traditional installation and disassembly methods.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figures 1-3 This utility model provides a technical solution: a dust removal device with an easy-to-replace filter element structure;

[0022] To improve the ease of installation and operation of filter element 4, a limiting seat 6 is provided on the surface of the dust collector body 1. A slot 7 is formed on the surface of the limiting seat 6, and the filter element 4 is positioned above the limiting seat 6. A retaining plate 8 and a limiting post 9 are provided on the surface of the lower limiting ring 5. A spring 10 and a limiting cylinder 11 are fitted onto the limiting post 9. A partition 2 is fixed to the upper part of the interior of the dust collector body 1. Several upper limiting rings 3 are symmetrically fixed to the bottom surface of the partition 2. The upper end of the filter element 4 is positioned within the upper limiting ring 3, and the lower end of the filter element 4 is positioned within the lower limiting ring 5. The filter element 4 is installed... During installation, the filter element 4 is placed inside the dust collector body 1, with the bottom of the filter element 4 positioned in the lower limit ring 5. Then, the lower limit ring 5 is rotated via the clamping plate 8, moving the clamping plate 8 to the opening of the clamping slot 7. The clamping plate 8 is slowly loosened, and the lower limit ring 5 is supported upward by the elastic spring 10. During its movement, the filter element 4 is supported upward. When the top of the filter element 4 is inserted into the upper limit ring 3, the filter element 4 is installed and fixed. Compared with the traditional method of installing the filter element 4 using multiple sets of bolts, this method is simpler and more efficient.

[0023] Example 2

[0024] To improve the stability of the lower limit ring 5 based on Embodiment 1, the limiting post 9 is fixed to the bottom surface of the lower limit ring 5, and the bottom end of the limiting cylinder 11 is fixed to the inner bottom surface of the dust collector body 1. The limiting cylinder 11 is located inside the spring 10, with the upper end of the spring 10 pressing against the bottom surface of the lower limit ring 5 and the lower end of the spring 10 abutting against the inner bottom surface of the dust collector body 1. The lower limit ring 5 is limited by the limiting post 9 inserted into the limiting cylinder 11 to prevent the lower limit ring 5 from being stopped.

[0025] In the event of detachment, the limiting post 9 is movably connected in the limiting cylinder 11, and the limiting cylinder 11 plays a limiting role in limiting the limiting post 9 to prevent it from detaching from the limiting cylinder 11, thereby ensuring the stability of the lower limiting ring 5 during use.

[0026] Example 3

[0027] Based on Embodiment 1, the ease of disassembly and assembly of filter element 4 is improved. When disassembling filter element 4, pressing the clamping plate 8 drives the lower limit ring 5 downward, causing the top of filter element 4 to disengage from the upper limit ring 3 and release its restriction. Adjust the position of the clamping plate 8 so that it moves to the opening of the slot 7, and then rotate the clamping plate 8 to move it into the slot 7 to limit the lower limit ring 5 and prevent it from moving upward. At this time, filter element 4 can be taken out from the lower limit ring 5. When filter element 4 needs to be disassembled for maintenance and cleaning, the ease of operation is improved. Compared with the traditional disassembly method, it is simpler to operate and conducive to improving efficiency.

[0028] In actual use, when installing filter element 4, place it inside the dust collector body 1, ensuring the bottom of filter element 4 is in the lower limit ring 5. Then, rotate the lower limit ring 5 via the clamping plate 8 to move the clamping plate 8 to the opening of the clamping slot 7. Slowly loosen the clamping plate 8, and the lower limit ring 5 will move upwards under the elastic support of the spring 10. During this movement, it will support the filter element 4 as it moves upwards. When the top of filter element 4 is inserted into the upper limit ring 3, the filter element 4 is installed and fixed. Compared with the traditional method of installing filter element 4 using multiple sets of bolts, this method is simpler and more efficient. The lower limit ring 5 is limited by the insertion of the limiting post 9 into the limiting cylinder 11 to prevent the lower limit ring 5 from detaching. The limiting post 9 is movable and connected... Connected to the limiting cylinder 11, the limiting cylinder 11 limits the limiting post 9, preventing the limiting post 9 from detaching from the limiting cylinder 11, thus ensuring the stability of the lower limiting ring 5 during use. When disassembling the filter element 4, the lower limiting ring 5 is moved downward by pressing the clamping plate 8, causing the top of the filter element 4 to disengage from the upper limiting ring 3 and release its limitation. The position of the clamping plate 8 is adjusted so that it moves to the opening of the clamping groove 7, and then the clamping plate 8 is rotated to move into the clamping groove 7 to limit the lower limiting ring 5, preventing the lower limiting ring 5 from moving upward. At this time, the filter element 4 can be taken out from the lower limiting ring 5. When the filter element 4 needs to be disassembled for maintenance and cleaning, the operation is more convenient and simpler than the traditional disassembly method, which is conducive to improving efficiency.
