Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment device. Background Art

[0002] Sewage refers to polluted water that contains various pollutants that can have a harmful effect on the aquatic environment (such as rivers, lakes, and oceans), ecosystems, and human health. Sewage comes from a wide range of sources and has complex and diverse components. It usually needs to be treated to meet the corresponding discharge standards or reuse standards. Domestic sewage mainly comes from daily household life, including kitchen drainage, toilet drainage, and laundry drainage, while industrial sewage is generated in various industrial production processes.

[0003] Sewage treatment requires multiple processes. Existing sewage treatment devices are not convenient for multi-stage filtration of sewage. When sewage enters the sewage tank, the garbage in the sewage tends to accumulate together and is difficult to disperse, which easily affects the circulation of sewage.

[0004] For example, in the Chinese patent with publication number CN218392420U, a multi-stage sewage treatment device is mentioned. Its specification discloses that sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, and catering. Sewage treatment equipment is an industrial equipment that can effectively treat urban domestic sewage, industrial wastewater, etc., and prevent sewage and pollutants from directly flowing into the water area. It is of great significance to improve the ecological environment, enhance the urban quality, and promote economic development. Most of the existing sewage treatment devices cannot perform multi-stage filtration, and cannot clean the impurities accumulated on the surface of the filter while filtering.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a first gear, a rack, a spring and a first filter. With the help of the first filter, the sewage entering the frame can be filtered. With the help of the transmission of the first gear and the rack, the separation frame can be shaken. Under the elastic force of the spring, the separation frame can be shaken repeatedly, thereby increasing the downstream speed of the sewage and avoiding the accumulation of too much debris as much as possible.

[0020] 2. The present invention sets a first bevel gear, a second bevel gear, a first belt, a second belt and a spiral blade. Under the transmission action of the second belt, the second belt drives the second bevel gear to rotate by connecting with the power source. The second bevel gear meshes with the first bevel gear, and then transmits power to the first bevel gear to start the first belt. The first belt then drives the spiral blade to rotate through transmission. The rotation of the spiral blade enables the sewage and flocculant in the treatment frame to be fully stirred and mixed, thereby enhancing the contact efficiency between the flocculant and the sewage. This process promotes the full reaction of pollutants in the sewage and the flocculant, improves the coagulation effect of the flocculant, further accelerates the separation and precipitation of pollutants in the sewage, and then accelerates the entire sewage treatment process. Through the synergistic effect of the transmission system, the mixing of sewage and flocculant is more uniform, the reaction is more sufficient, the mixing effect is significantly improved, the efficiency of subsequent treatment steps is optimized, and ultimately helps to ensure that the sewage treatment reaches a higher treatment standard.

[0021] 3. The present invention provides a cleaning brush and a slide tube. Under the sliding action of the slide tube, the cleaning brush can achieve precise movement through the guide system of the slide tube. When the slide tube slides along the predetermined track, the cleaning brush connected to the slide tube also slides synchronously with its movement direction. The cleaning brush contacts the second filter screen, and the impurities, dirt and sediment attached to the filter screen are effectively removed through the friction and wiping action between the bristles and the filter screen surface. This cleaning process can not only restore the filtering efficiency of the second filter screen, but also prevent the filter screen from being blocked or increasing resistance due to dirt accumulation.

At this time, the two springs 212 will be deformed. Since the tooth surface of the first gear 207 has a small number of teeth, when the rack 208 is not in contact with the first gear 207, the spring 212 rebounds, that is, it drives the separation frame 201 to rebound, and so on and so forth, causing the separation frame 201 to shake repeatedly, so as to facilitate the shaking of debris on the first filter screen 20101, thereby avoiding the accumulation of debris and affecting the flow of sewage.

[0040] It should be noted that the long rod 220 will be driven to rotate under the transmission of the second belt 222, and then the second bevel gear 219 will rotate. The second bevel gear 219 will transmit the transmission to the first bevel gear 218, and then the driving rod 216 will rotate. Under the action of the first belt 217, the rotating rod 213 will rotate, and then the spiral piece 215 will rotate.

[0042] In an optional embodiment: a cleaning mechanism 3 is provided on the surface of the purification frame 203, and the cleaning mechanism 3 includes two first L-shaped rods 301 fixedly connected to the side walls of the purification frame 203, and the two first L-shaped rods 301 are symmetrically distributed about the vertical center axis of the purification frame 203, and the arc surfaces of the two first L-shaped rods 301 are slidably connected to sliding tubes 302, and the arc surfaces of the two sliding tubes 302 are fixedly connected to L-shaped plates 303, and the ends of the two L-shaped plates 303 close to each other are fixedly connected to cleaning brushes 304.

[0044] It should be noted that by pulling the gripping rod 306 , the sliding tube 302 is driven to slide along the arc surface of the first L-shaped rod 301 , so that the cleaning brush 304 moves along the surface of the second filter screen 20301 , thereby achieving the effect of cleaning the second filter screen 20301 .

[0045] The working principle of the present invention is as follows: when in use, the staff pours sewage from the outlet pipe 102 into the separation frame 201. Under the action of the first filter screen 20101, impurities in the sewage can be filtered, and the motor 206 is started at the same time to drive the first gear 207 to rotate, and the first gear 207 drives the rack 208 to move.

Since the number of teeth on the tooth surface of the first gear 207 is small, when the rack 208 is not in contact with the first gear 207, the spring 212 rebounds, that is, drives the separation frame 201 to rebound, and so on and so forth, so that the separation frame 201 is repeatedly shaken, which is convenient for shaking the debris on the first filter screen 20101, and avoids the accumulation of debris and affecting the flow of sewage. The sewage flows from the separation frame 201 to the processing frame 202.

Under the action of the first belt 217, the rotating rod 213 will rotate, thereby rotating the spiral piece 215. The staff puts flocculant from the feed pipe 20202, and the flocculant enters the processing frame 202. Under the rotation of the spiral piece 215, the flocculant and the sewage are mixed. When the flocculant fully reacts with the sewage in the processing frame 202, the valve at the bottom of the processing frame 202 is opened to release the sewage and enter the purification frame 203. The sewage will first contact the second filter screen 20301 to filter the debris. The filtered sewage is discharged from the outlet pipe 102. When the second filter screen 20301 needs to be cleaned, the grip rod 306 is directly pulled to drive the slide tube 302 to slide along the arc surface of the first L-shaped rod 301, so that the cleaning brush 304 moves along the surface of the second filter screen 20301 to achieve the effect of cleaning the second filter screen 20301.
