Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filtration mechanism and its wastewater treatment device. Background Technology

[0002] Wastewater treatment refers to the use of physical, chemical, and biological methods to treat wastewater, purify it, reduce pollution, and ultimately achieve wastewater recycling, reuse, and full utilization of water resources.

[0003] The most basic step in wastewater treatment is filtration to remove particulate impurities from the wastewater. Basket filters are a common type of filtration component. They contain a slanted filter screen. Wastewater enters the filter screen from the lower side and is then filtered and discharged through the higher side.

[0004] However, wastewater contains some large solid particles that impact the inner wall of the filter cylinder, potentially damaging it and causing the filter holes to enlarge. This prevents the filter cylinder from filtering small solid particles in the wastewater, thus reducing the filtration efficiency. To address this, we propose a filtration mechanism and its wastewater treatment device. Utility Model Content

[0005] The purpose of this invention is to provide a filtration mechanism and its wastewater treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration mechanism, comprising:

[0007] The outer wall of the cylindrical body is symmetrically provided with liquid-passing components;

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] This utility model provides, for example Figure 1-3 The filtration mechanism shown includes a cylinder 101 and a filter assembly. A liquid-passing assembly is symmetrically arranged on the outer wall of the cylinder 101. The liquid-passing assembly includes an outer pipe 801, which is symmetrically and fixedly inserted into the outer wall of the cylinder 101. A second connecting ring 802 is fixedly sleeved on the outer wall of the outer pipe 801. A plurality of third connecting holes 803 are opened on one side of the second connecting ring 802. Wastewater enters the cylinder 101 through one of the outer pipes 801, is filtered by the filter assembly, and is discharged through the other outer pipe 801.

[0025] In a preferred embodiment, the filter assembly is disposed inside the cylinder 101. The filter assembly includes a filter cylinder 201 with an obliquely cut top. A filter screen 202 is fixedly connected to the inner wall of the filter cylinder 201. The filter screen 202 is obliquely arranged, and the pore size of the filter screen 202 is larger than that of the filter cylinder 201. Wastewater enters the filter cylinder 201 through the lower top opening. The wastewater undergoes a first filtration through the filter screen 202 and then a second filtration through the higher outer wall of the filter cylinder 201. This ensures that large solid particles in the wastewater can only damage the filter screen 202, avoiding damage to the inner wall of the filter cylinder 201. Consequently, small particles in the wastewater cannot pass through the filter cylinder 201, ensuring the filtration effect. When large solid particles damage the filter screen 202 by impact, it only enlarges the pores within the filter screen 202, but the large solid particles still cannot pass through the filter screen 202.

[0026] The filter cylinder 201 is fixedly connected to the top end of a first edge ring 301. The outer wall of the first edge ring 301 is fitted to the inside of the cylinder 101. A guide mechanism is provided between the first edge ring 301 and the inner wall of the cylinder 101. The gap between the filter cylinder 201 and the inner wall of the cylinder 101 is reduced by the first edge ring 301.

[0027] A second edge ring 401 is fixedly connected to the outer wall of the filter screen 202 and located outside the filter screen cylinder 201. The outer wall of the second edge ring 401 is fitted to the inner wall of the cylinder 101, and the second edge ring 401 reduces the gap between the filter screen 202 and the inner wall of the cylinder 101.

[0028] The guiding mechanism includes a fixing strip 501, which is fixedly connected to the inner wall of the cylinder 101. The outer wall of the first edge ring 301 is provided with a guide groove 502. The outer wall of the fixing strip 501 is slidably connected to the inner wall of the guide groove 502. Through the mutual limiting of the fixing strip 501 and the guide groove 502, the filter screen cylinder 201 can be positioned after being inserted into the cylinder 101. This ensures that the lower position of the filter screen cylinder 201 is symmetrically aligned with the water inlet pipe 801, and the higher position of the filter screen cylinder 201 is aligned with the water outlet pipe 801, thus ensuring the stable operation of the filtration mechanism.

[0029] The top of the cylinder 101 is provided with a first connecting ring 602. A fixing mechanism is provided between the first connecting ring 602 and the cylinder 101. The first connecting ring 602 is used to seal the cylinder 101 to prevent wastewater from flowing out through the top opening of the cylinder 101. When it is necessary to clean the filter assembly, the first connecting ring 602 can be opened and the filter assembly can be taken out.

[0030] The fixing mechanism includes a top cover 601, which is fixedly sleeved on the outer wall of the cylinder 101. The top end of the first connecting ring 602 has multiple first connecting holes 603. The inner wall of the first connecting hole 603 is movably connected to a fixing bolt 605. The top end of the top cover 601 has a second connecting hole 604. The outer wall of the fixing bolt 605 is movably connected to the inner wall of the second connecting hole 604. A fixing nut 606 is threaded onto the outer wall of the fixing bolt 605 and located below the top cover 601. By having the fixing bolt 605 pass through the first connecting hole 603 and the second connecting hole 604 in sequence, and then tightening the fixing nut 606 on the outer wall of the fixing bolt 605, the first connecting ring 602 and the top cover 601 can be fixed, thereby fixing the first connecting ring 602 to the cylinder 101 and improving the working stability of the first connecting ring 602.

[0031] A sealing gasket 701 is provided between the top cover 601 and the cylinder 101. The top of the sealing gasket 701 has multiple movable holes 702. The outer wall of the fixing bolt 605 is movably inserted and connected to the inner wall of the movable holes 702. The sealing gasket 701 seals the first connecting ring 602 and the top cover 601, preventing wastewater from flowing out through the gap between the first connecting ring 602 and the top cover 601, thus ensuring the stability of the first connecting ring 602 in use.

[0032] This utility model also provides a wastewater treatment device, including the above-mentioned filtration mechanism.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
