Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a dust collector which is convenient for replacing a filter element. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. There is a filter element inside the dust collector, which will be clogged with dust after long-term use, so it needs to be replaced regularly. If it is not replaced for a long time, it will affect the dust removal effect of the dust collector.

[0003] The filter element inside the existing dust collector is often fixed inside the dust collector by bolts, etc., which is extremely inconvenient when it needs to be replaced. For this reason, we propose a dust collector that is easy to replace the filter element. To this end, the utility model provides a dust collector that is easy to replace the filter element to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a dust collector that is easy to replace the filter element, which solves the above problems. When the filter element needs to be replaced, the electromagnet is started by a remote control to generate magnetic force, and the limit block can be attracted by the magnetic force to move and compress the spring. At this time, all the limit blocks have been pulled out of the holes of the plug block to release the restriction on the assembly block. Then, the air filter element body can be slowly pulled out by the handle for replacement, and the entire operation process is very simple and convenient; when the air filter element body is replaced, the plug block is inserted into the assembly block and the electromagnet is controlled by the remote control again to demagnetize it, and then the limit block is inserted into the hole of the plug block by the elastic force of the compressed spring to complete the restriction and fixation again. Since the air filter element body is not fixed by a large number of bolts and is fixed by a remote control controller, ordinary tools cannot be effectively disassembled, which is beneficial to the safety of the device. Some irrelevant personnel cannot disassemble it without a remote control; by starting the hydraulic rod, the height of the outer protective tube can be raised through the protruding block and the fixing ring to facilitate the docking operation of ventilation ducts with different heights above the ground.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a dust collector that is easy to replace the filter element, including an outer protective tube, a convenient replacement component is arranged inside the outer protective tube, and an auxiliary component is arranged on the outer wall of the outer protective tube; the convenient replacement component includes an assembly block, the assembly block is fixedly connected to the inside of the outer protective tube, and a limiting groove is arranged on the inner wall of the outer protective tube. The convenient replacement component also includes an air filter element body, the outer wall of the air filter element body is fixedly connected with a slider, and the slider is slidably connected with the inside of the limiting groove, one end of the air filter element body is fixedly connected with an insert block, and the insert block is inserted into the inside of the assembly block, and an electromagnet is fixedly installed on the outer wall of the outer protective tube, and a hole is arranged inside the side wall of the outer protective tube, and one end of the electromagnet is inserted into the hole, and one end of the electromagnet is fixedly connected with a spring, and one end of the spring is fixedly connected with the limiting block, and the limiting block is slidably connected with the hole arranged inside the side wall of the outer protective tube and the inner wall of the hole of the insert block, and the electromagnet is controlled to start by a remote controller.

[0006] Furthermore, one end of the outer protection tube is threadedly connected to a conical cover, and one side of the conical cover is threadedly connected to a dustproof and breathable cover.

[0007] The above technical solution is used to prevent some larger debris from floating into the outer protective tube.

[0008] Furthermore, an exhaust fan is fixedly mounted on the inner wall of the conical cover.

[0009] By adopting the above technical solution, air is sucked in through the exhaust fan.

[0010] Furthermore, a handle is fixedly connected to one end of the air filter element body.

[0011] By adopting the above technical solution, the air filter element body can be quickly pulled out by the handle.

[0012] Furthermore, the auxiliary component includes a fixing ring, and a protruding block is fixedly connected to the outer wall of the fixing ring.

[0013] The above technical solution is adopted to connect the hydraulic rod and protect the outer protective tube.

[0014] Furthermore, the auxiliary component also includes a cushion block, a hydraulic rod is fixedly installed inside the cushion block, and a movable end of the hydraulic rod is fixedly connected to the bottom of the protruding block.
