Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater and waste gas technology, and in particular to a detachable industrial wastewater filter. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via various pathways; some cause direct harm, while others have a cumulative effect, further jeopardizing human health. Different substances have different effects. Currently, industrial waste gas and wastewater treatment often employs fixed, integrated structural designs, which makes subsequent maintenance and replacement inconvenient.

[0003] Existing technologies have the following problems:

[0004] Extensive searches revealed that patent application CN202123205945.1 discloses a filter for industrial waste gas and wastewater treatment. This patent allows waste gas or wastewater to enter the main treatment chamber through an inlet pipe. The waste gas or wastewater undergoes initial filtration under the filtration and isolation of the internal filter lining of the main treatment chamber. The filtered waste gas or wastewater then moves towards the snap-fit ​​plate. Due to the S-shaped arrangement of the internal filter plates in the snap-fit ​​plate channel, the waste gas or wastewater flows in an alternating manner within the main treatment chamber for filtration. After prolonged use, the internal filter lining can be replaced by removing the sealing cover. Simultaneously, the sealing top plate can be pulled out from the top snap-fit ​​groove, thereby extending the snap-fit ​​plate and allowing for the replacement of the internal filter plates in the snap-fit ​​plate channel.

[0005] However, the aforementioned patent still has some problems in actual use. The most obvious problem is that multiple filters need to be removed one by one from the processing box for replacement, which is cumbersome and time-consuming, increasing downtime costs.

[0006] To address these shortcomings, we propose a detachable industrial wastewater filter. Utility Model Content

[0007] The purpose of this invention is to provide a detachable industrial wastewater filter to address the shortcomings of existing technologies.

[0032] Specifically, it improves the filtration effect and efficiency of industrial wastewater.

[0033] In this implementation plan, the mesh size of filter screen 7 increases sequentially from left to right.

[0034] Specifically, it can perform multi-stage filtration treatment of industrial wastewater.

[0035] In this implementation plan: the lid 3 fits into the processing box 1.

[0036] Specifically, it serves to seal the seal and prevent water leakage.

[0037] Working principle: During use, several filter screens 7 are set on the cover 3. By opening the cover 3, several filter screens 7 can be taken out from the processing box 1 at one time, improving the efficiency of filter screen 7 disassembly and assembly and greatly reducing the time wasted due to downtime. The modular design makes it convenient and labor-saving to replace and maintain the filter screens 7. Specifically, by pressing the positioning block 14 and storing the positioning block 14 in the storage groove 12, the filter screen 7 can be removed from the cover 3 by moving it horizontally. This is beneficial for replacing individual filter screens 7 that are severely clogged or damaged, reducing maintenance costs. It should be noted that, as shown in the attached diagram of the instruction manual, the diameter of the end of the positioning pin 11 that is away from the support plate 6 is slightly larger, so it can limit the positioning block 14 and prevent the positioning block 14 from moving excessively.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
