Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and in particular to a dust explosion-proof baghouse dust collector. Background Technology

[0002] Many industrial sectors, such as steel metallurgy, cement building materials, and chemical manufacturing, generate large amounts of dust during production. This dust not only pollutes the environment but may also pose a serious threat to workers' health. Baghouse dust collectors filter dust-laden gas through filter bags, trapping dust particles on the surface of the bags, thus greatly improving dust removal efficiency. Therefore, it is necessary to design a dust explosion-proof baghouse dust collector.

[0003] To address this, patent CN219290972U discloses a dust explosion-proof bag filter, comprising a fan, an air inlet, a dust chamber, a clean air chamber, an outlet chamber, an antistatic dust bag, an air pump, an outlet, a dust hopper, and a base. The dust chamber and clean air chamber are respectively equipped with humidifying nozzles and water mist nozzles. A water collection trough is located at the bottom of the dust hopper. The clean air chamber also includes a temperature sensor, which is connected to a controller via wires. The controller's signal output is connected to the signal input of the water mist nozzle. This invention overcomes the shortcomings of existing technologies where water sprayers spray the entire filter tower by humidifying and reducing dust in the dust chamber and atomizing and cooling in the clean air chamber. It avoids problems such as excessive humidity in the filter bags and difficulty in cleaning dust adhesion, which reduce dust removal efficiency. Simultaneously, it can reduce the temperature of the filter bags, achieving an explosion-proof effect.

[0004] Although the dust explosion-proof bag filter mentioned above can reduce the temperature of the filter bag and prevent explosion during use, the filter bag is prone to damage during long-term use and is not easy to replace. Therefore, it is necessary to design a dust explosion-proof bag filter. Utility Model Content

[0005] The purpose of this utility model is to provide a dust explosion-proof bag filter to solve the problem that the filter bags of existing dust explosion-proof bag filters are prone to damage and are not easy to replace during long-term use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust explosion-proof bag filter, including a dust collector body;

[0007] The top of the dust collector body is equipped with a bag removal structure;

[0008] The bag removal structure includes an installation horizontal plate fixed to the inner wall of the top of the dust collector body. The installation horizontal plate has a reserved groove inside, and a support frame is fixed to the top of the installation horizontal plate outside the reserved groove.

[0009] The outer side of the support frame is provided with a cloth bag body, the bottom end of the cloth bag body is fixed with a connecting ring, the top end of the connecting ring is uniformly provided with a cover plate, the interior of the connecting ring and the cover plate is uniformly penetrated by a positioning shaft, and the outer wall of the top of the positioning shaft is threaded with a limit bolt.

[0010] Furthermore, the dust collector body includes a shell, an inner cavity, an air inlet, a dust outlet, a pressure sensor, and an air outlet. The inner cavity is opened inside the shell. An air inlet is fixed at the middle position of the bottom of the shell. A dust outlet is fixed at the low end of the shell on one side of the air inlet. A pressure sensor is fixed on the inner wall of the shell at the top of the inner cavity. An air outlet is fixed at the top of the shell.

[0011] Furthermore, a turbulence structure is fixed at the bottom of the inner cavity, and a pretreatment structure is fixed on the inner wall of the outer shell above the turbulence structure.

[0012] Furthermore, aeration pipes are fixed on both sides of the top of the outer shell, and an air compressor is connected to the end of the aeration pipe away from the bag body.

[0013] Furthermore, the turbulence structure includes a turbulence sleeve, a mounting base, and turbulence holes. The mounting base is fixed to the inner wall of the outer shell at the bottom of the inner cavity. The turbulence sleeve is threaded onto the outer wall of the mounting base. Turbulence holes are provided on both sides inside the turbulence sleeve.

[0014] Furthermore, the turbulence holes are symmetrically distributed on both sides of the turbulence sleeve, and the side view cross-section of the turbulence holes is circular.

[0015] Furthermore, the pretreatment structure includes a mounting plate, a connecting plate, a filter plate, an electric telescopic rod, and a top plate. The mounting plates are all fixed to the inner wall of the outer shell above the turbulence sleeve. A connecting plate is fixedly installed on the top of each mounting plate. A filter plate is fixed between adjacent connecting plates. Electric telescopic rods are installed on the inner walls of the outer shell on both sides below the filter plates. A top plate is fixed to the top of each electric telescopic rod.

[0016] Furthermore, the filter plate has uniformly distributed filter holes inside, and the top plate is symmetrically distributed on both sides of the filter plate.

[0017] Furthermore, the bottom end of each positioning shaft is fixedly connected to the top end of the mounting plate, and the positioning shafts are evenly distributed inside the cover plate.

[0018] The dust explosion-proof bag filter provided by this utility model has the following advantages:

[0019] By incorporating a bag disassembly structure, the bag body can be supported by the support frame, facilitating the filtration of dust and gas. The bag body can be pre-positioned by the limiting action of the connecting ring and the positioning shaft. The connecting ring can be pressed and fixed by the pressing action of the cover plate, preventing the connecting ring from warping and leaking air. The threaded connection of the limiting bolt can strengthen the fixation. The bag body can be cleaned by the gas impact action of the aeration pipe, causing dust to fall off. This device achieves the functions of easy installation and easy disassembly of the bag body, improving the convenience of using the dust explosion-proof bag dust collector.

[0020] With the pre-treatment structure, the filter plate can be fixed inside the inner cavity by the fixed connection of the mounting plate and the connecting plate, which facilitates the initial filtration of dust gas. The extension and retraction of the electric telescopic rod can facilitate the impact of the filter plate through the top plate, which can shake the dust at the bottom of the filter plate to the bottom of the inner cavity. This realizes that the device has the function of facilitating the pre-filtration of dust gas and improves the working efficiency of the dust explosion-proof bag dust collector during use.

[0021] By incorporating a turbulence-inducing structure, the direction of gas entry into the inner cavity can be altered under the turbulence-inducing effect of the turbulence sleeve. This allows dust-laden gas to enter the inner cavity through the turbulence holes, preventing dust and impurities inside the gas from falling downwards due to inertia upon entry and thus avoiding blockage of the air inlet. The threaded connection between the turbulence sleeve and the mounting base facilitates the replacement of the turbulence sleeve, enabling the device to have an anti-clogging function and improving the applicability of the dust explosion-proof bag filter during use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides a dust explosion-proof bag filter, which includes a dust collector body 1.

[0031] Reference Figures 1-6 The dust collector body 1 includes a shell 11, an inner cavity 12, an air inlet 13, a dust outlet 14, a pressure sensor 15, and an air outlet 16. The inner cavity 12 is formed inside the shell 11. The air inlet 13 is fixed at the middle of the bottom of the shell 11. The dust outlet 14 is fixed at the lower end of the shell 11 on one side of the air inlet 13. The pressure sensor 15 is fixed on the inner wall of the shell 11 at the top of the inner cavity 12. The air outlet 16 is fixed at the top of the shell 11. A bag removal structure 5 is provided on the top of the dust collector body 1. The bag removal structure 5 includes a mounting plate fixed to the inner wall of the top of the dust collector body 1. A horizontal plate 53 is installed, and a reserved groove 58 is opened inside the horizontal plate 53. A support frame 51 is fixed to the top of the horizontal plate 53 outside the reserved groove 58. A bag body 52 is set outside the support frame 51. A connecting ring 54 is fixed to the bottom of the bag body 52. ​​A cover plate 56 is evenly arranged at the top of the connecting ring 54. A positioning shaft 55 is evenly inserted through the inside of the connecting ring 54 and the cover plate 56. A limit bolt 57 is threaded on the outer wall of the top of the positioning shaft 55. The bottom of the positioning shaft 55 is fixedly connected to the top of the horizontal plate 53. The positioning shafts 55 are evenly distributed inside the cover plate 56.

[0032] When installing the bag body 52, the bag body 52 is fitted onto the outside of the support frame 51. Then, the connecting ring 54 is fitted onto the positioning shaft 55 to pre-fix the bag body 52. ​​Next, the cover plate 56 is fitted onto the outside of the positioning shaft 55 so that the cover plate 56 can press and hold the connecting ring 54. Then, the limit bolt 57 is threaded onto the outer wall of the top of the positioning shaft 55 to fix the cover plate 56 and the connecting ring 54. Under the monitoring of the pressure sensor 15, if the pressure inside the inner cavity 12 is too high, the data will be transmitted to the back-end terminal in time, so that the staff can carry out timely maintenance and prevent explosion.

[0033] Reference Figures 1-3 and Figure 5 The bottom of the inner cavity 12 is fixed with a turbulence structure 2. The turbulence structure 2 includes a turbulence sleeve 21, a mounting base 22 and turbulence holes 23. The mounting base 22 is fixed to the inner wall of the outer shell 11 at the bottom of the inner cavity 12. The turbulence sleeve 21 is threadedly connected to the outer wall of the mounting base 22.

[0036] During installation, the connecting plate 32 is placed on top of the mounting plate 31, and then the mounting plate 31 and the connecting plate 32 are fixedly connected with bolts. The filter plate 33 can filter the rising dust gas. The electric telescopic rod 34 is activated. The extension and retraction of the electric telescopic rod 34 can drive the top plate 35 to extend and retract. When the electric telescopic rod 34 is extended, it can drive the top plate 35 to impact the bottom of the filter plate 33, which can facilitate the impact and dust removal of the dust at the bottom of the filter plate 33, so that the dust can fall to the bottom of the inner cavity 12.
