Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a press brush fixing component used in wastewater treatment equipment. Background Technology

[0002] In the wastewater industry, the internal flow bar screen auxiliary equipment, the press, mainly consists of a machine body, a screw, a filter screen, a motor, and brushes. Its working principle is to separate the waste from the water by squeezing the waste with the screw and then pushing out the squeezed waste. Among them, the brush plays a key role in cleaning the filter screen mesh blockage, but in actual use, this component has obvious defects.

[0003] Currently, most brushes are fixed to the screw by welding. After long-term operation, the part in contact with the filter screen is easily worn. Once the brush is worn, the filter screen will become clogged and unable to work properly, causing the press to lose its ability to press waste. Moreover, the brush replacement cycle is very short, averaging once a month. Because it is fixed by metal welding, the replacement process is extremely cumbersome. First, the machine body is disassembled and the screw is pulled out; then, the brush to be replaced is cut to ensure that it can be removed smoothly; then, the new brush is welded to the screw; finally, the screw and machine body are reinstalled so that the equipment can be put back into use. The entire process requires two workers to work together each time, and the whole process takes up to 4 hours, consuming a lot of manpower and resources. This not only affects the normal operation efficiency of the equipment, but also significantly increases maintenance costs and workload. Utility Model Content

The connecting part passes through the through holes in the fixing part and the pressing plate and is fixed to the screw. The end of the pressing plate away from the through hole is welded to the screw.

[0006] Preferably, the through hole on the pressure plate is configured as a sliding hole, used to adjust the position of the connecting part and the fixing part, thereby adjusting the diameter of the brush.

[0007] Preferably, it includes at least two connecting portions, namely a first connecting portion and a second connecting portion, wherein the first connecting portion passes through the through hole of the fixing portion; and the second connecting portion passes through the through holes of the fixing portion and the pressure plate.

[0021] To further illustrate the technical means and effects adopted by the present invention to achieve its intended utility model objective, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a press brush fixing component for wastewater treatment equipment according to the present invention. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] The following description, in conjunction with the accompanying drawings, details a specific solution for a press brush fixing component in a wastewater treatment equipment provided by this utility model.

[0024] Please combine Figure 1 and Figure 2 The first embodiment of this utility model provides a press brush fixing component for a sewage treatment equipment, for a detachable press brush 4, including: a pressure plate 1 and a connecting component 2. The press includes a screw 3. The connecting component 2 includes a fixing part 20 and a connecting part 21. Both the fixing part 20 and the pressure plate 1 are provided with through holes 22. The end of the fixing part 20 away from the pressure plate 1 is provided with a slot 200 for embedding the brush 4 and fastening it through the connecting part 21. The connecting part 21 passes through the through holes 22 on the fixing part 20 and the pressure plate 1 and is fixed to the screw 3. The end of the pressure plate 1 away from the through holes 22 is welded to the screw 3.

[0025] To better illustrate, in wastewater treatment equipment, the press is equipped with brushes 4 for handling solid particles and impurities. However, these brushes 4 may wear out or be damaged during use. In existing technologies, replacing the brushes 4 is cumbersome, which not only increases maintenance costs but also consumes time and effort, affecting the overall operating efficiency of wastewater treatment. Therefore, this application proposes a brush fixing component for the press in wastewater treatment equipment to facilitate portable replacement of the brushes 4 and achieve efficient maintenance.

[0026] Preferably, in this embodiment, the pressure plate 1 and the fixing part 20 are precision machined from 304 stainless steel, which can ensure their durability and stability; and the length of the slot 200 can be customized according to actual use needs, adapting to brushes 4 of different specifications and sizes, thus expanding the scope of application; the welding between the pressure plate 1 and the spiral 3 does not require disassembling the spiral 3 component, simplifying the installation process of the brush 4.

[0027] As an optional implementation, the connecting part 21 is a screw, and the through hole 22 is a threaded hole that matches the screw, so as to fasten the screw and make the fixing part 20 stablely connected to the pressure plate 1 and the brush 4.

[0028] Furthermore, the through hole 22 on the pressure plate 1 is set as a sliding hole to adjust the position of the connecting part and the fixing part 20, thereby realizing the diameter adjustment of the brush 4.

[0029] Furthermore, it includes at least two connecting parts 21, namely a first connecting part 210 and a second connecting part 211. The first connecting part 210 passes through the through hole 22 of the fixing part 20; the second connecting part 211 passes through the through hole 22 of the fixing part 20 and the pressure plate 1.

[0030] It can be explained that the vertical upward position of the brush 4 is precisely controlled based on the adjustment between the second connecting part 211 and the sliding hole. Specifically, when adjusting the position of the brush 4, the first connecting part 210 is first loosened to eliminate the constraint of the fixing part 20 on the brush 4 and ensure the normal operation of the connecting assembly 2. During the adjustment process, the brush 4 will generate a contraction effect along with the upward movement between the second connecting part 211 and the fixing part 20, that is, the diameter of the brush 4 expands with the adjustment process, resulting in a corresponding shortening of its axial length. This switches the wear surface of the press, thereby extending the service life of the brush 4 and ensuring the continuous and efficient operation of the press.

[0031] Please combine Figure 3 and Figure 4 Furthermore, a snap-fit ​​part 201 is provided at the opening of the slot 200. The snap-fit ​​part 201 snaps into the brush 4 and is fastened by the first connecting part 210. That is, the snap-fit ​​part 201 snaps into the brush 4 to stabilize the brush 4. Then, the brush 4 is fixed to the press screw 3 by fastening the first connecting part 210.

[0032] Furthermore, the end of the fixing part 20 near the pressure plate 1 is provided corresponding to the pressure plate 1 and is fitted with the pressure plate 1; optionally, the pressure plate 1 has an L-shaped structure, and the end of the fixing part 20 near the pressure plate 1 is correspondingly set to an L-shaped structure. The two L-shaped structures fit together to form a rectangular body, and the cooperation between the sliding hole and the second connecting part 211 can make the brush 4 more smoothly, avoid affecting the operation of the press screw 3, and improve the operating efficiency.

[0033] Working principle: When the brush 4 needs to be replaced, rotate the screw 3 and loosen the connecting part 21 in sequence to disassemble the brush 4 and take it out; then insert the new brush 4 into the slot 200 and engage it with the engaging part 201. Rotate the screw 3 to tighten it with the first connecting part 210. Insert the fixing part 20 into the pressure plate 1 as a whole, and fit the fixing part 20 and the pressure plate 1 together. According to the current usage requirements, control the tightening position of the second connecting part 211 to determine the current fixed height of the brush 4, so that the brush 4 is stable and does not loosen, thus achieving brush 4 height control; finally, reinstall the screw 3 and the body of the press. This simplifies the maintenance manpower for brush 4 replacement, reduces maintenance costs, is easy to install, flexible to adjust, and more efficient in maintenance.

[0034] It should be noted that the order of the above embodiments of the present invention is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. The processes depicted in the accompanying drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
