DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 , the present invention provides a technical solution: a graded dust removal industrial dust collector that is convenient for cleaning the filter element, including multiple independent dust removal mechanisms;

[0026] The structures of the multiple independent dust removal mechanisms are all the same, and one of the independent dust removal mechanisms includes a dust removal box 1 which is vertically arranged and has an open top, and the inner surface of the upper part of the inner cavity of the dust removal box 1 is fixedly connected with a lap frame 2 which matches the inner contour thereof, and a filter element plate 4 is detachably mounted on the top of the lap frame 2, and a plurality of filter element holes 7 are vertically penetrated through the upper surface of the filter element plate 4, and a bag filter element 8 is detachably mounted inside the plurality of filter element holes 7;

[0027] The filter element plate 4 is provided with a plurality of fastening structures corresponding to the plurality of bag filter elements 8 respectively.

[0028] Multiple independent dust removal mechanisms are evenly spaced along the length direction of a straight line. The front surfaces of multiple dust removal boxes 1 and the upper and lower parts of the filter element plates 4 are respectively connected with air inlet ducts 11 and air outlet ducts 12. The air inlet ducts 11 and air outlet ducts 12 of every two adjacent independent dust removal mechanisms are connected to each other through a connecting pipe 13.

[0029] The front parts of the inner cavities of the multiple dust removal boxes 1 are all vertically fixedly connected with baffles 14.

[0030] The device connects a plurality of independent dust removal mechanisms through a connecting pipe, and the filter apertures of the bag filter elements 8 used in the plurality of independent dust removal mechanisms are successively reduced, thereby achieving a multi-stage dust removal effect, thereby improving the dust removal effect of the overall operation.

[0031] The exhaust duct 12 of the independent dust removal mechanism at the end is connected to an exhaust device. When the exhaust device is in operation, negative pressure will be generated. Since multiple independent dust removal mechanisms are interconnected, the exhaust gas containing dust can be extracted through the air inlet duct 11 on the independent dust removal mechanism at the front end. After the exhaust gas enters the independent dust removal mechanism, it will move downward under the action of the baffle 14, and then it will come into contact with multiple bag filters 8. The dust mixed inside will be blocked outside by the bag filters 8, and the gas will move upward through the bag filters 8, pass through the filter plate 4, and then move to the upper layer of the dust removal box 1, and then move to the next independent dust removal mechanism through the exhaust duct 12 and the connecting pipe 13. This reciprocating process can form a multi-stage filtration effect.

[0032] A plurality of first connection holes 3 are vertically penetrated on the upper surface of the lap frame 2, and a plurality of second connection holes 5 corresponding to the plurality of first connection holes 3 are vertically penetrated on the outer edge of the upper surface of the filter element plate 4. The filter element plate 4 is detachably mounted on the upper surface of the lap frame 2 via the plurality of first connection holes 3, the plurality of second connection holes 5 and a bolt structure.

[0033] The lap frame 2 and the filter element plate 4 are linked to each other by a bolt structure, and the bag filter elements 8 are installed on the filter element plate 4. When the filter element needs to be cleaned, the filter element plate 4 can be directly removed from the lap frame 2 to remove the entire filter element plate 4 and the filter element thereon from the inside of the device. Then the filter element can be directly cleaned without manually removing them one by one, thereby improving the cleaning efficiency.

[0034] The upper surface of the lap frame 2 is provided with a plurality of installation grooves along the contour direction thereof, and the interiors of the plurality of installation grooves are all fixedly connected with rubber sealing strips 6 .

[0035] The plurality of rubber sealing strips 6 can improve the sealing performance between the lap frame 2 and the filter element plate 4 after they are installed, thereby preventing dust from flowing out from the gap between the two.

[0036] The structures of multiple fastening structures are all the same, and one of the fastening structures includes a fixed magnetic ring 19 fixedly connected to the upper surface of the filter element plate 4 and located outside a filter element hole 7, and a connecting magnetic ring 20 that is mutually attracted to the fixed magnetic ring 19 is detachably mounted on the upper surface of the fixed magnetic ring 19, and a clamping ring 21 is fixedly connected to the top of the connecting magnetic ring 20, and a plurality of support bars 22 that are adapted to the length of the cloth bag filter 8 are vertically fixedly connected to the bottom end of the inner edge of the clamping ring 21.

[0037] The fastening structure can compress the bag filter element 8 and also improve the overall sealing performance of the device. In actual use, after the bag filter element 8 is installed, the multiple support bars 22 of the fastening structure are inserted into the interior of the bag filter element 8 until the connecting magnetic ring 20 of the fastening structure is completely fitted with the fixed magnetic ring 19. At this time, the two will not be easily separated under the action of magnetic force, and at this time, the lower surface of the clamping ring 21 will be tightly fitted to the upper surface of the bag filter element 8, improving its tightness with the release surface of the filter element plate 4, and the multiple support bars 22 can support the bag filter element 8 to ensure that its vertical state will not be skewed.

[0038] A closing cover 9 is detachably mounted on the top of the dust removal box 1 via a bolt structure, and a pulse dust removal device 18 is provided on the top of the closing cover 9 .

[0039] The outer edge of the closing cover 9 and the outer edge of the dust removal box 1 are both provided with a flange ring 10, and the two are connected by the flange ring 10. When it is necessary to remove the filter element plate 4, the closing cover 9 needs to be removed first. The pulse dust removal device 18 on the closing cover 9 can periodically emit pulses to vibrate the dust accumulated on the bag filter 8, so that the dust can fall into the ash hopper at the bottom of the dust removal box 1.

[0040] A fixed frame 15 is fixedly connected to the outer surfaces of the plurality of dust removal boxes 1 , and a plurality of supporting legs 16 are vertically fixedly connected to the bottom ends of the plurality of dust removal boxes 1 .

[0041] A plurality of reinforcing ribs 17 are fixedly connected between every two adjacent supporting legs 16 .

[0042] The fixed frame 15 can link multiple independent dust removal mechanisms to each other, the multiple support legs 16 play a supporting role, and the multiple reinforcing ribs 17 further improve the overall stability of the device.

[0043] When the device is actually running, the exhaust pipe 12 of the most independent dust removal mechanism at the end is connected to an exhaust device. After the exhaust device is running, negative pressure will be generated. Since multiple independent dust removal mechanisms are interconnected, the exhaust gas with dust can be extracted through the air inlet pipe 11 on the most front independent dust removal mechanism. After the exhaust gas enters the independent dust removal mechanism, it will move downward under the action of the baffle 14, and then it will contact multiple bag filter elements 8. The dust mixed inside will be blocked outside by the bag filter element 8, and the gas will move upward through the bag filter element 8 and pass through the filter element plate. 4, and then moves to the upper layer of the dust removal box 1, and then moves to the next independent dust removal mechanism through the air outlet pipe 12 and the connecting pipe 13, so that a multi-stage filtering effect can be formed by this reciprocating movement. At the same time, the lap frame 2 and the filter element plate 4 are linked to each other by a bolt structure, and the bag filter elements 8 are installed on the filter element plate 4. When the filter element needs to be cleaned, the filter element plate 4 is directly removed from the lap frame 2, and the entire filter element plate 4 and the filter element thereon can be taken out from the inside of the device. Then the filter element can be directly cleaned without manually removing them one by one, thereby improving the cleaning efficiency.
