Technical Field
[0001] This invention belongs to the field of explosion-proof dust removal filter cartridge replacement. Background Technology
[0002] Dust accumulates on the surface of filter cartridges in filtration dust collectors over time, thus inhibiting gas permeability. Therefore, the more frequently filter cartridges are replaced, the lower the filtration efficiency, flow rate, and energy consumption. The replacement process for existing filter cartridges in filtration dust collectors is cumbersome. During disassembly, it is necessary to unscrew the bolts on the top of the dust collector housing, then use a hoisting device to lift open the upper shell of the dust collector housing, loosen the multiple flange bolts fixing the filter cartridges one by one with tools, and then open the inspection door to remove the filter cartridges. Conversely, when installing filter cartridges, multiple flange bolts are also required to lock and seal the filter cartridges, and the process of removing the top cover of the dust collector housing is cumbersome and complicated. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a quick sealing and fitting device for the filter cartridge of an explosion-proof dust collector. The sealing process avoids the cumbersome flange connection method. After the filter cartridge slides along the guide rail to the predetermined position, the corresponding electromagnet can be opened to achieve quick sealing.
[0004] Technical solution: To achieve the above objectives, the present invention provides a quick sealing and fitting device for an explosion-proof dust collector filter cartridge, comprising a partition, wherein the lower side of the partition is the chamber to be filtered and the upper side is the chamber that has been filtered.
[0005] The upper side of the partition is equipped with several rows of funnel-shaped filter cartridge outlets arranged in an integrated array; the lower side of the partition is horizontally fixed with several equally spaced parallel slide rails, and several filter cartridges are movably supported between any two adjacent slide rails. In the unlocked state, the filter cartridges between any two adjacent slide rails can slide along the slide rail direction under the action of external force to align with the corresponding filter cartridge outlet above.
[0006] Furthermore, each filter cartridge is coaxially provided with an annular sealing component at its upper end; the outer diameter of the annular sealing component is larger than the outer diameter of the filter cartridge.
[0007] Each slide rail has a support slide bar extending integrally along its length on both sides; the two support slide bars on the side of the two slide rails that are close to each other support the lower surfaces of the two sides of the annular sealing member at the upper end of the filter cylinder; in the unlocked state, there is a gap between the upper end of the annular sealing member and the lower surface of the partition.
[0008] Furthermore, several arrays of electromagnets are fixedly installed in the filter chamber by a bracket;
[0009] Each filter cartridge has an iron disc fixed coaxially on its lower end wall. When any filter cartridge slides along the slide rail until it is aligned with the air outlet of the corresponding filter cartridge above, the iron disc at the lower end of the filter cartridge is aligned coaxially with the top of an electromagnet. When the electromagnet is energized, it exerts a downward electromagnetic pull on the filter cartridge above under the action of electromagnetic force. The annular sealing component automatically seals with the lower surface of the partition under the transmission of this electromagnetic pull.
[0010] Furthermore, the upper end of the filter cartridge is coaxially and integrally connected with an annular inner edge, which is composed of an integrated lower horizontal annular wall, an upper horizontal annular wall, and a vertical annular wall; the upper and lower ends of the vertical annular wall are integrally connected to the inner rings of the upper and lower horizontal annular walls along the contour, respectively; the outer ring of the lower horizontal annular wall is integrally connected to the upper end of the filter cartridge along the contour, and the inner ring of the vertical annular wall is the air outlet of the filter cartridge.
[0011] Furthermore, the annular sealing component includes a horizontal ring. The inner, middle, and outer rings on the upper side of the horizontal ring are integrally provided with an inner vertical ring wall, a middle vertical ring wall, and an outer vertical ring wall, respectively. The inner vertical ring wall is located between the upper and lower horizontal ring walls, and the inner vertical ring wall slides with the outer ring of the vertical ring wall. The lower surface of the horizontal ring is in a limiting fit with the upper surface of the lower horizontal ring wall. There is a travel gap between the upper end face of the inner vertical ring wall and the upper horizontal ring wall. The outer ring of the upper horizontal ring wall slides or has a clearance fit with the inner wall of the middle vertical ring wall. The lower surfaces on both sides of the horizontal ring are supported upwards by two adjacent support strips.
[0012] A horizontal annular elastic wall is coaxially arranged between the middle vertical ring wall and the outer vertical ring wall. The upper sides of the middle vertical ring wall and the outer vertical ring wall are both integrally provided with an a-elastic wall bonding ring edge. The inner and outer rings of the horizontal annular elastic wall are respectively bonded to the lower surfaces of the two a-elastic wall bonding ring edges along the contour by a sealing adhesive. The lower side of the horizontal annular elastic wall is an a-annular hydraulic chamber.
[0013] A circular elastic wall with an arc-shaped, upward-convex cross-section is coaxially arranged between the middle vertical ring wall and the inner vertical ring wall. On the side of the middle vertical ring wall and the inner vertical ring wall that are close to each other, a b-shaped elastic wall bonding ring edge is integrally provided. The inner and outer rings of the circular elastic wall with an arc-shaped, upward-convex cross-section are respectively bonded along the contour to the lower surface of the two b-shaped elastic wall bonding ring edges by a sealing adhesive. The lower side of the circular elastic wall with an arc-shaped, upward-convex cross-section is a b-shaped hydraulic chamber.
[0014] The lower part of the vertical ring wall of the middle ring has several horizontally hollowed-out connecting holes, which connect the a-ring hydraulic chamber and the b-ring hydraulic chamber to each other; the annular elastic wall with a circular arc convex upward supports the horizontal ring wall of the column.
[0015] Furthermore, both the horizontal annular elastic wall and the annular elastic wall with a convex, circular cross-section are made of elastic rubber.
[0016] Furthermore, both the a-ring hydraulic chamber and the b-ring hydraulic chamber are filled with hydraulic oil.
[0017] Furthermore, a method for quickly sealing and installing a filter cartridge in a quick-sealing device for an explosion-proof dust collector is characterized by:
[0018] Open the inspection door on the side of the dust collector filter box, slide the annular sealing component at the top of one filter cartridge horizontally between two adjacent slide rails, and make the two supporting slide bars on the side of the two adjacent slide rails close to each other lift up the lower surfaces of the annular sealing component at the top of the filter cartridge; under the action of external force, the filter cartridge between the two adjacent slide rails gradually slides along the slide rail direction until it is aligned with the air outlet of the corresponding filter cartridge above. At this time, control the electromagnet below the filter cartridge to be energized.
[0019] Beneficial effects: The sealing process of the explosion-proof dust collector filter cartridge of the present invention does not rely on the cumbersome flange connection method. After the filter cartridge slides along the guide rail to the predetermined position, the corresponding electromagnet can be turned on to achieve a quick seal. When disassembling, simply turn off the corresponding electromagnet to release the seal and engagement state, and slide it out along the guide rail. Attached Figure Description

[0025] The invention will now be further described with reference to the accompanying drawings.
[0026] As attached Figures 1 to 5The device shown is a quick-sealing assembly for an explosion-proof dust collector filter cartridge. It includes a dust collector filter box with horizontal partitions 18 separating the filter chamber. The lower side of partition 18 is the chamber to be filtered, and the upper side is the filtered chamber. It also includes a gas inlet pipe and a filtered gas outlet pipe. The outlet of the gas inlet pipe connects to the chamber to be filtered, and the inlet of the filtered gas outlet pipe connects to the filtered chamber. A negative pressure pump is installed on the filtered gas outlet pipe. When the negative pressure pump operates, a negative pressure is created in the filtered chamber. Therefore, the gas in the chamber to be filtered below partition 18 passes through several filter cartridges 4 under the negative pressure and reaches the filtered chamber, thus achieving filtration.
[0027] like Figure 1 and 2 As shown, the upper side of the partition 18 is integrally arrayed with several rows of funnel-shaped air outlets 17; the lower side of the partition 18 is horizontally fixed with several equally spaced parallel slide rails 2, and several filter cylinders 4 are movably supported between any two adjacent slide rails 2. The side wall of the filter cylinder 4 is a cylindrical filter wall of porous material, such as a polyester filter cylinder. In the unlocked state, the filter cylinder 4 between any two adjacent slide rails 2 can slide along the slide rail 2 under the action of external force until it is aligned with the corresponding air outlet 17 above.
[0028] Each filter cartridge 4 has an annular sealing member 50 coaxially arranged at its upper end; the outer diameter of the annular sealing member 50 is larger than the outer diameter of the filter cartridge 4, and a support slide bar 3 is integrally arranged on both sides of each slide rail 2 along its length; the two support slide bars 3 on the side of the two slide rails 2 that are close to each other support the lower surfaces of the annular sealing member 50 on both sides of the upper end of the filter cartridge 4; in the unlocked state, there is a gap 19 between the upper end of the annular sealing member 50 and the lower surface of the partition plate 18, which facilitates sliding. Figure 1 and 2 As shown.
[0029] Several arrayed electromagnets 15 are fixedly installed in the filter chamber by a bracket; an iron plate 16 is coaxially fixed on the lower end wall of each filter cylinder 4; when any filter cylinder 4 slides along the slide rail 2 until it is coaxially aligned with the air outlet 17 of the corresponding filter cylinder above, the iron plate 16 at the lower end of the filter cylinder 4 is exactly coaxially aligned with the top of an electromagnet 15. When the electromagnet 15 is energized, it forms a downward electromagnetic pull on the filter cylinder 4 above under the action of electromagnetic force. The annular sealing member 50 automatically seals with the lower surface of the partition 18 under the transmission of this electromagnetic pull.
[0030] like Figure 4 and 5As shown, the upper end of the filter cartridge 4 is coaxially and integrally connected to an annular inner edge 1. The annular inner edge 1 is composed of an integral lower horizontal annular wall 1.3, an upper horizontal annular wall 1.1, and a vertical annular wall 1.2. The upper and lower ends of the vertical annular wall 1.2 are integrally connected to the inner rings of the upper horizontal annular wall 1.1 and the lower horizontal annular wall 1.3 along their respective contours. The outer ring of the lower horizontal annular wall 1.3 is integrally connected to the upper end of the filter cartridge 4 along its contour. The inner ring of the vertical annular wall 1.2 is the filter cartridge outlet 70. In the installed state, the filter cartridge outlet 70 is coaxially connected to the corresponding filter cartridge outlet nozzle 17.
[0031] like Figure 4 and 5 As shown, the annular sealing component 50 includes a horizontal ring 14. The inner ring, middle ring, and outer ring on the upper side of the horizontal ring 14 are integrally provided with an inner ring vertical ring wall 13, a middle ring vertical ring wall 9, and an outer ring vertical ring wall 43, respectively. The inner ring vertical ring wall 13 is located between the upper horizontal ring wall 1.1 and the lower horizontal ring wall 1.3, and the inner ring vertical ring wall 13 slides with the outer ring of the vertical ring wall 1.2. The lower surface of the horizontal ring 14 is limited to the upper surface of the lower horizontal ring wall 1.3. There is a travel gap 60 between the upper end face of the inner ring vertical ring wall 13 and the upper horizontal ring wall 1.1. The outer ring of the upper horizontal ring wall 1.1 slides or has a clearance fit with the inner wall of the middle ring vertical ring wall 9. The lower surfaces on both sides of the horizontal ring 14 are supported upward by two adjacent support strips 3.
[0032] A horizontal annular elastic wall 5 is coaxially arranged between the middle vertical ring wall 9 and the outer vertical ring wall 43. An elastic wall bonding ring edge 6 is integrally provided on the upper side of the middle vertical ring wall 9 and the outer vertical ring wall 43 that are close to each other. The inner and outer rings of the horizontal annular elastic wall 5 are respectively bonded to the lower surface of the two elastic wall bonding ring edges 6 along the contour by a sealing adhesive. The lower side of the horizontal annular elastic wall 5 is an annular hydraulic chamber 10.
[0033] A circular elastic wall 8 with an arc-shaped, upward-convex cross-section is coaxially disposed between the middle vertical ring wall 9 and the inner vertical ring wall 13. An elastic wall bonding ring edge 7 is integrally disposed on the side of the middle vertical ring wall 9 and the inner vertical ring wall 13 that are close to each other. The inner and outer rings of the circular elastic wall 8 with an arc-shaped, upward-convex cross-section are respectively bonded to the lower surface of the two elastic wall bonding ring edges 7 along the contour by a sealing adhesive. The lower side of the circular elastic wall 8 with an arc-shaped, upward-convex cross-section is a circular hydraulic chamber 12.
[0034] The lower part of the vertical ring wall 9 of the middle ring has several horizontally hollowed-out connecting holes 11, which connect the a-ring hydraulic chamber 10 and the b-ring hydraulic chamber 12 to each other; the annular elastic wall 8 with a circular arc convex cross section supports the horizontal ring wall 1.1 on the column.
[0035] Both the horizontal annular elastic wall 5 and the annular elastic wall 8 with a convex arc cross-section are made of elastic rubber; the a-annular hydraulic chamber 10 and the b-annular hydraulic chamber 12 of this invention are filled with hydraulic oil.
[0036] Sealing installation process for any filter cartridge 4:
[0037] After opening the maintenance door on the side of the dust collector filter box, slide the annular sealing member 50 at the upper end of one filter cylinder 4 horizontally between two adjacent slide rails 2, and make the two supporting slide bars 3 on one side of the two adjacent slide rails 2 close to each other lift up the lower surfaces of both sides of the annular sealing member 50 at the upper end of the filter cylinder 4; at this time, the annular elastic wall 8 with a convex arc cross section on the annular sealing member 50 lifts up the upper horizontal annular wall 1.1, and the upper horizontal annular wall 1.1 applies the weight of the filter cylinder 4 downward to the annular elastic wall 8 with a convex arc cross section in the form of pressure N, thereby causing the b-annular hydraulic chamber 12 to... The internal pressure increases due to the squeezing force. The pressure in the b-shaped hydraulic chamber 12 is transmitted to the a-shaped hydraulic chamber 10 through the connecting hole 11. The increased internal pressure in the a-shaped hydraulic chamber 10 pushes the originally horizontally taut horizontal annular elastic wall 5 upward, causing the horizontal annular elastic wall 5 to arch slightly upward. The highest point of the slightly arched horizontal annular elastic wall 5 is still not higher than the upper surface of the bonding ring edge 6 of the two a-elastic walls. Therefore, there is still a gap 19 between the uppermost end of the annular sealing member 50 and the lower surface of the partition 18, which facilitates the subsequent sliding before alignment.
[0038] Subsequently, the annular sealing member 50 at the upper end of the filter cylinder 4 is pushed along the length of the slide rail 2 by a robotic arm or manual push rod. This causes the filter cylinder 4 between two adjacent slide rails 2 to gradually slide along the slide rail 2 under the action of external force until it is coaxially aligned with the corresponding air outlet 17 of the filter cylinder above. At this time, the iron plate 16 at the lower end of the filter cylinder 4 is exactly coaxially aligned with the top of an electromagnet 15. At this time, the electromagnet 15 below the filter cylinder 4 is energized, and under the action of electromagnetic force, a downward electromagnetic pull is formed on the filter cylinder 4 above. Under the action of electromagnetic force, the upper horizontal annular wall 1.1 applies downward force to the cross-section of the circular... The pressure N of the arc-shaped convex annular elastic wall 8 increases significantly. The upper horizontal annular wall 1.1 further presses the arc-shaped convex annular elastic wall 8 downwards, making it more horizontal. This causes the hydraulic oil in the b-shaped annular hydraulic chamber 12 to be squeezed into the a-shaped annular hydraulic chamber 10 under pressure through the connecting hole 11. This causes the originally slightly arched horizontal annular elastic wall 5 to arch significantly further. The highest point of the significantly arched horizontal annular elastic wall 5 seals and presses against the lower surface of the partition plate 18, thus achieving a sealing fit between the annular sealing component 50 and the partition plate 18, thereby realizing the sealing installation process of the filter cartridge.
[0039] In summary, the sealing process of the explosion-proof dust collector filter cartridge in this solution does not rely on a cumbersome flange connection method. After the filter cartridge slides along the guide rail to the predetermined position, the corresponding electromagnet can be turned on to achieve a quick seal. When disassembling, simply turn off the corresponding electromagnet to release the seal and engagement state, and it can slide out along the guide rail. The energy consumption of the electromagnet in this solution is negligible compared to the overall energy consumption.
[0040] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
