Description

Technical Field

[0001] This utility model relates to the technical field of bag filter equipment, specifically a deformation-resistant housing for a bag filter. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] Because baghouse dust collectors generate internal pressure during operation, the shell is prone to deformation after long-term use, affecting the normal operation and service life of the dust collector. In addition, traditional shell structures lack effective support and reinforcement measures when subjected to pressure, which can easily lead to local deformation or even cracking. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the casing of a bag filter is prone to deformation after long-term use due to the internal pressure generated during operation, which affects the normal operation and service life of the dust collector. In addition, the traditional casing structure lacks effective support and reinforcement measures when subjected to pressure, which can easily lead to local deformation or even cracking. Therefore, this utility model provides a deformation-resistant casing for a bag filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant housing for a bag filter, comprising a dust collector body, the dust collector body including an inner housing and an outer housing disposed outside the inner housing, support columns for support being vertically and evenly arranged in the middle of the inner housing and the outer housing, reinforcing ribs for strengthening the support being evenly and fixedly installed in the middle of the two sets of support columns, a first fixing strip being fixedly installed on the outside of the outer housing, a second fixing strip being fixedly installed directly below the first fixing strip, a column for increasing the strength of the outer housing being provided in the middle of the first fixing strip and the second fixing strip, and a crossbeam being fixedly installed in the middle of the two sets of columns.

[0006] As a further embodiment of this utility model: a fixing block is fixedly installed at the top of the column and fixedly installed with the first fixing strip, and a fixing groove is evenly provided at the bottom end of the first fixing strip to be fixedly installed with the fixing block; a wedge block is slidably connected at the bottom end of the column and engages with the second fixing strip; and a slot is evenly provided at the top end of the second fixing strip to engage with the wedge block.

[0007] As a further embodiment of this utility model: a reset spring is fixedly installed on the inner side of the bottom end of the column and fixedly installed with the wedge block; a through groove is opened at one end of the column and on one side of the wedge block; a connecting rod is fixedly installed at one end of the wedge block, and a sliding plate is fixedly installed through the through groove on the connecting rod.

[0008] As a further improvement of this utility model, a protective pad to mitigate external impact is fixedly installed at one end of the column near the outer shell.

[0009] As a further embodiment of this utility model: a dust hopper is fixedly installed at the bottom of the dust collector body, and a dust inlet pipe is provided at one end of the dust hopper; a venturi tube is fixedly installed at one end of the dust collector body; and an air outlet pipe is provided at one end of the dust collector body.

[0010] As a further embodiment of this utility model: a support rod is fixedly installed at the bottom of the dust collector body, and the support rod is symmetrically and evenly fixedly installed around the bottom of the dust collector body.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 5In this embodiment of the utility model, a bag filter anti-deformation shell includes a dust collector body 1. The dust collector body 1 includes an inner shell 11 and an outer shell 12 disposed outside the inner shell 11. Support columns 14 for support are vertically and evenly arranged in the middle of the inner shell 11 and the outer shell 12. Reinforcing ribs 13 to strengthen the support are evenly fixedly installed in the middle of the two sets of support columns 14. A first fixing strip 15 is fixedly installed on the outside of the outer shell 12. A second fixing strip 16 is fixedly installed directly below the first fixing strip 15. A column 17 to increase the strength of the outer shell 12 is arranged in the middle of the first fixing strip 15 and the second fixing strip 16. A crossbeam 117 is fixedly installed in the middle of the two sets of columns 17.

[0023] Through the implementation of this method: the support column 14 is a hollow steel pipe, the reinforcing rib 13 is a steel bar, the outer shell 12 and the inner shell 11 are both made of steel plate, and the surface of the outer shell 12 is provided with an anti-corrosion coating. By setting the support column 14 and the reinforcing rib 13 between the outer shell 12 and the inner shell 11, the strength and stability of the shell can be effectively enhanced, preventing deformation due to internal pressure during operation. At the same time, the setting of the column 17 and the crossbeam 117 further improves the overall strength of the shell, enabling it to withstand greater pressure and external forces.

[0024] Reference Figures 1 to 5 The top of the column 17 is fixed with a fixing block 110 that is fixedly installed with the first fixing strip 15, and the bottom end of the first fixing strip 15 is evenly provided with fixing grooves 19 that are fixedly installed with the fixing block 110. The bottom end of the column 17 is slidably connected with a wedge block 112 that is engaged with the second fixing strip 16. The top end of the second fixing strip 16 is evenly provided with a slot 113 that is engaged with the wedge block 112. The inner side of the bottom end of the column 17 is fixedly installed with a return spring 111 that is fixedly installed with the wedge block 112. One end of the column 17 and one side of the wedge block 112 is provided with a through groove 114. One end of the wedge block 112 is fixed with a connecting rod 116, and the connecting rod 116 passes through the through groove 114 and is fixedly installed with a sliding plate 115.

[0025] By implementing this method, the wedge block 112, the return spring 111, the fixing groove 19, and the fixing block 110 can quickly fix the column 17 to the outer periphery of the outer shell 12, increasing the installation speed. When disassembling, simply lift the sliding block 115 upwards to drive the wedge block 112 out of the slot 113, and the column 17 can be quickly disassembled, which facilitates quick replacement of the column 17 and the crossbeam 117 if they are damaged later.

[0026] Reference Figures 1 to 5 One end of the column 17 is fixedly installed with a protective pad 18 to reduce external impact at the other end near the outer shell 12;

[0027] By implementing this method, the protective pad 18 can absorb the impact on the outer shell 12, reduce the damage to the outer shell 12, and reduce the possibility of deformation and damage to the outer shell 12.

[0028] Reference Figures 1 to 5 A dust hopper 4 is fixedly installed at the bottom of the dust collector body 1, and a dust inlet pipe 5 is provided at one end of the dust hopper 4. A venturi tube 3 is fixedly installed at one end of the dust collector body 1, and an air outlet pipe 2 is provided at one end of the dust collector body 1. A support rod 6 is fixedly installed at the bottom of the dust collector body 1, and the support rod 6 is symmetrically and evenly fixedly installed around the bottom of the dust collector body 1.

[0029] The working principle of this utility model is as follows: By setting a support column 14 and a reinforcing rib 13 between the outer shell 12 and the inner shell 11, the strength and stability of the shell can be effectively enhanced, preventing deformation due to internal pressure during operation. At the same time, the setting of the column 17 and the crossbeam 117 further improves the overall strength of the shell, enabling it to withstand greater pressure and external forces. When installing the column 17, simply insert the fixing block 110 at the top of the column 17 into the fixing groove 19 at the bottom of the first fixing strip 15, and then press the bottom of the column 17. When the wedge block 112 at the bottom of the column 17 is squeezed, It will be stored inside the column 17. When the wedge block 112 is pressed directly above the slot 113, the return spring 111 inside the column 17 will automatically spring the wedge block 112 into the slot 113 to complete the fixation, increasing the installation speed of the column 17. When disassembling, simply lift the sliding plate 115 upwards to lift the wedge block 112 out of the slot 113. Then, remove the bottom end of the column 17 from the inside of the second fixing strip 16. After that, simply pull down to quickly disassemble the column 17, which is convenient for quick replacement if the column 17 and the crossbeam 117 are damaged in the future.
