Description

Technical Field

[0001] The present application relates to the field of gas filtering equipment, and in particular to a cartridge dust collector that is easy to replace. Background Art

[0002] A dust collector is a device that separates dust from flue gas. A cartridge dust collector is a dust collector that uses cartridges as filter elements. It has the advantages of reasonable structure, high dust removal efficiency, and significant energy saving. It is widely used in dust and dust treatment in building materials, light industry, metallurgy, chemical industry and other industries. A general cartridge dust collector includes an air inlet duct, a filter chamber and an air outlet duct. A cartridge device is installed in the filter chamber. Dust-containing gas enters from the air inlet duct, is processed by the cartridge device, and is discharged from the air outlet duct.

[0003] The filter cartridge device is the key part of the filter cartridge dust collector, and the filter cartridge is the key component of the filter bag device. Generally, the filter cartridge in the filter cartridge dust collector is fixed to the fixing plate at the upper end of the filter chamber by multiple bolts and other fasteners. This structure makes it inconvenient to disassemble and assemble the filter cartridge. When the filter cartridge is damaged, it needs to be replaced, and the replacement time is long, which increases the unnecessary downtime of the filter cartridge dust collector, thereby reducing the dust removal efficiency of the filter cartridge dust collector. Utility Model Content

[0004] In order to improve the convenience of filter cartridge replacement, the present application provides a filter cartridge dust collector that is easy to replace.

[0005] The present application provides a filter cartridge dust collector that is easy to replace and adopts the following technical solution:

[0006] A filter cartridge dust collector that is easy to replace, comprising a box body, the box body is provided with an air inlet and a plurality of air outlets, the box body is provided with mounting holes having the same number as the air outlets, the box body is detachably connected with a plurality of filter cartridges, one end of the filter cartridge is arranged at the air outlet, and the other end of the filter cartridge is arranged in the mounting hole;

[0007] A accommodating cavity and a sliding groove are provided on the box body around the multiple mounting holes and air outlets, a cylinder is provided in each accommodating cavity, a baffle for covering the mounting hole and the air outlet is provided at the free end of the cylinder, and the baffle is slidably arranged in the sliding groove; a control switch for controlling the cylinder is provided on the box body, and the control switch is provided in multiple numbers and corresponds one-to-one to the mounting holes and the air outlets.

[0009] A further technical solution is that a sealing ring is arranged in the slide groove.

[0010] This application has the following beneficial technical effects:

[0011] The filter cartridge is set on the box body. While playing a filtering role, it also keeps the trigger point of the travel switch in a triggered state. When the filter cartridge needs to be replaced, pull the filter cartridge out directly. The filter cartridge releases the travel switch, which allows the switch to immediately control the cylinder so that the baffle is blocked at the air outlet; when the filter cartridge is completely removed from the box body, the travel switch at the mounting hole controls the corresponding cylinder to move, thereby blocking the mounting hole. When installing the filter cartridge, the filter cartridge first triggers the travel switch, allowing the cylinder to drive the baffle to open the mounting hole and the air outlet installed in place, so that the filter cartridge can be replaced without stopping the machine, and can effectively prevent the dust-carrying airflow in the box from flowing out.

[0015] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0016] The present application discloses a cartridge dust collector that is easy to replace. Figure 1~Figure 2 The dust collector includes a box body 1, which is provided with an air inlet 11 and a plurality of air outlets 12. The box body 1 is provided with mounting holes 13 having the same number as the air outlets 12. A plurality of filter cartridges 2 are detachably connected to the box body 1, one end of the filter cartridge 2 is arranged at the air outlet 12, and the other end of the filter cartridge 2 is arranged in the mounting hole 13.

[0017] The box body 1 is provided with a receiving cavity 21 and a slide groove 22 around the plurality of mounting holes 13 and the air outlet 12. A cylinder 23 is provided in each receiving cavity 21. A baffle 24 for shielding the mounting hole 13 and the air outlet 12 is provided at the free end of the cylinder 23. The baffle 24 is slidably provided in the slide groove 22. Specifically, a convex block 26 is provided on one side of the baffle 24 adjacent to the cylinder 23. The piston rod end of the cylinder 23 is fixedly provided on the convex block 26 to drive the baffle 24 to move in the slide groove 22. A control switch for controlling the cylinder 23 is provided on the box body 1. The control switch is provided in plurality and corresponds to the mounting holes 13 and the air outlet 12 one by one.

[0018] The control switch is a travel switch 25, the travel switch 25 near the air outlet 12 is arranged on the inner side of the housing 1, and the travel switch 25 near the mounting hole 13 is arranged on the outer side of the housing 1, and the trigger point of the travel switch 25 protrudes to the mounting hole 13 or the inner side of the air outlet 12. When the filter cartridge 2 is installed on the housing 1, the outer wall of the filter cartridge 2 is always squeezed to form the trigger end of the switch; when the filter cartridge 2 is detached from the housing 1, the travel switch 25 is reset.

[0019] Furthermore, a sealing ring (not shown in the drawings) is provided in the slide groove 22. When the cylinder 23 drives the baffle 24 to slide out of the slide groove 22 and cover the air outlet 12, it can dock on the sealing ring. Combined with the thrust of the cylinder 23, the sealing performance of the baffle 24 can be improved.

[0020] The implementation principle of the embodiment of the present application is as follows: the filter cartridge 2 is arranged on the box body 1, and the dusty gas enters from the air inlet 11 and is filtered by the filter cartridge 2 to form relatively pure air and is sent out from the air outlet 12. While the filter cartridge 2 plays a filtering role, it also applies pressure to the trigger point of the travel switch 25 so that it is always in a triggered state. When the filter cartridge 2 needs to be replaced, the filter cartridge 2 is directly pulled out, and the end of the filter cartridge 2 adjacent to the air outlet 12 first gives up the position of the slide slot 22 of the air outlet 12. When the end of the filter cartridge 2 adjacent to the air outlet 12 is separated from the air outlet 12 and separated from the corresponding travel switch 25, the travel switch 25 is reset, so that the forming switch can immediately control the cylinder 23 to extend the baffle 24, so that the baffle 24 slides down from the slide slot 22 and blocks the air outlet 12, preventing the dust airflow in the box body 1 from being emitted outward from the air outlet 12; when the end of the filter cartridge 2 passes through the mounting hole 13 and separates from the corresponding travel switch 25, the travel switch 25 at the mounting hole 13 controls the corresponding cylinder 23 to move, and the cylinder 23 drives the baffle 24 to block the mounting hole 13, preventing the dust airflow in the box body 1 from leaking out from the mounting hole 13.

[0021] When installing the filter cartridge 2, the filter cartridge 2 first triggers the travel switch 25 near the installation hole 13, the cylinder 23 moves back and drives the baffle 24 to open the installation hole 13, and the filter cartridge 2 is inserted into the box body 1 from the installation hole 13. When the filter cartridge 2 touches the travel switch 25 near the air outlet 12, the corresponding cylinder 23 moves back and drives the baffle 24 to open the air outlet 12, so that the filter cartridge 2 can be installed in place. In this way, a single filter cartridge 2 or multiple filter cartridges 2 can be replaced in sequence without stopping the machine, and the airflow with dust in the box body 1 can be effectively prevented from flowing out.
