[0001] The utility model relates to the technical field of sewage impurity cleaning equipment, in particular to impurity cleaning equipment for sewage treatment. Background Art

[0002] Wastewater treatment: The process of purifying wastewater to ensure it meets the required quality for discharge into a water body or reuse. Wastewater treatment is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life.

[0003] In the sewage treatment process, there are many impurities in the sewage that require multiple filtrations before subsequent biological treatment processes with higher requirements, such as aeration tanks, can be carried out. During the filtration, impurities need to be continuously cleaned. However, the existing impurity cleaning equipment has the problem of inconvenient internal cleaning and maintenance, and impurities easily accumulate and cause blockage, thereby affecting the impurity cleaning efficiency. Based on this, an impurity cleaning equipment for sewage treatment is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an impurity cleaning device for sewage treatment to solve the problems raised in the above background technology.

Two fixing rings 17 are fixedly installed inside the tank body 3. A mounting ring 20 is movably installed on one side of the two fixing rings 17. A filter screen 16 is fixedly installed on the inner side of the mounting ring 20. A movable ring 18 is movably installed on the side of the mounting ring 20 away from the fixing ring 17. The internal thread of the movable ring 18 is connected with a number of fixing bolts 19. A cross bracket 21 is fixedly installed on the inside of the tank body 3 away from the flange plate 8. A support bearing 12 is fixedly installed on the opposite end of the cross bracket 21. A rotating rod 14 is sleeved on the inner side of the support bearing 12. A number of turbine blades 13 are fixedly installed on one end of the rotating rod 14, and a number of brush rods 15 are fixedly installed on the other end of the rotating rod 14.

[0020] The working principle of the above technical solution is as follows: when in use, the user connects the water inlet pipe 10 and the water outlet pipe 9 to the water inlet pump and the water outlet end respectively. When the water flows in, the water flow hits the turbine blades 13, prompting the turbine blades 13 to rotate and driving the rotating rod 14 to rotate, thereby causing the brush rod 15 to rotate and scrape the outside of the filter screen 16. After the impurities filtered by the filter screen 16 are intercepted, the heavier ones are deposited in the second outlet pipe 5 at the bottom, and the lighter ones float on the top of the second outlet pipe 5. They are convenient for operators to handle by stacking and are processed through regular discharge and salvage. Then, after the smaller impurities pass through the filter screen 16, they are filtered and intercepted by another filter screen 16. The impurities are blocked and limited on the inner side of the first outlet pipe 4 and salvaged through the circulating salvage equipment. Finally, the water flow that has filtered the impurities is discharged through the outlet pipe 9 for the next process. The overall operation is convenient, the structure is simple, and it is easy to filter. Impurities can overflow from the first outlet pipe 4 and the second outlet pipe 5 through the accumulation effect. The brush rod 15 reduces blockage and increases the convenience of operation.

[0021] In another embodiment, Figure 1-Figure 3 As shown, the flange plate 8 is fixed to the flange ring 7 and the outer side of the tank body 3 by bolt insertion, and a sealing ring is provided at the connection between the flange plate 8 and the tank body 3.

[0022] Through the provided flange ring 7 and flange plate 8, when the tank body 3 and the filter screen 16 need to be cleaned and maintained, the flange plate 8 is removed, and the operator enters the interior of the tank body 3 and removes the fixing bolts 19, so that the movable ring 18 and the mounting ring 20 can be removed, and then the filter screen 16 can be removed for cleaning and maintenance. The interior of the tank body 3 can also be cleaned and maintained, which is convenient for cleaning, increases the ease of use of the structure, and indirectly increases the service life.

[0023] In another embodiment, Figure 3 and Figure 4 As shown, the movable ring 18 is movably sleeved inside the tank body 3, and the fixing bolts 19 are threadedly connected and pass through the movable ring 18 and the mounting ring 20 and extend to the inside of the fixing ring 17. The fixing bolts 19 are evenly distributed in a circumferential manner inside the movable ring 18 and the fixing ring 17.

[0024] The arrangement of the movable ring 18 and the fixing bolts 19 facilitates the disassembly and assembly of the movable ring 18 and the support frame 2 through the fixing bolts 19, facilitates the clamping and limiting of the mounting ring 20, and facilitates maintenance and cleaning, thereby facilitating the replacement of accessories and maintenance and reducing blockage.

[0025] In another embodiment, Figure 1-Figure 3 As shown, there are two filter screens 16 , and the filter pore sizes of the two filter screens 16 are respectively one large and one small. The first outlet pipe 4 and the second outlet pipe 5 are respectively connected to one side of the two filter screens 16 .

[0026] The two filters 16 intercept and filter large and small impurities, which are convenient for classification and cleaning. In actual production, valves are set inside the first outlet pipe 4 and the second outlet pipe 5 at the bottom. When the valves are opened, the precipitated impurities are flushed out under the action of water pressure, which is convenient for discharge operations. The first outlet pipe 4 and the second outlet pipe 5 at the top are centrally salvaged by salvaging equipment, which is convenient for different discharge classifications and preliminary filtering and cleaning of impurities. In addition, valves are also set on the water inlet pipe 10 and the water outlet pipe 9 in the scheme, which are convenient for opening and closing as needed.

[0027] In another embodiment, Figure 3 and Figure 4 As shown, the turbine blades 13 are evenly distributed on the outer side of one end of the rotating rod 14 in a circumferential manner, and the turbine blades 13 are located on a side close to the water inlet pipe 10 .

[0028] The turbine blades 13 are impacted by the water flow, so that they rotate and apply the rotational action to the rotating rod 14, thereby driving the brush rod 15 to rotate, so as to rotate without a power source.

[0029] In another embodiment, Figure 3 and Figure 4 As shown, the brush rods 15 are evenly distributed on the outside of one end of the rotating rod 14 in a circumferential manner, and the brush portion of the brush rod 15 is in sliding contact with one side of the larger filter screen 16.

[0030] When the brush rod 15 rotates with the rotating rod 14, it performs a scraping operation on the filter screen 16, which is convenient for reducing the possibility of impurities clogging the filter screen 16, increasing the convenience of the structure, increasing the fluidity of impurities, and moving the impurities to the periphery of the filter screen 16, which is convenient for preventing clogging and facilitating filtration.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
