[0004] However, in the prior art, during the deep treatment of sewage, if impurities such as residues in the wastewater clog the filtering equipment, the water flow of the sewage treatment will become smaller, which will not only affect the effect of sewage treatment, but also prevent the sewage from flowing smoothly, resulting in a significant reduction in the sewage flow received by subsequent secondary treatment equipment. If the blockage cannot be resolved in time, impurities will continue to accumulate in the filter tank, causing equipment such as water pumps in the entire sewage treatment process to be under operating pressure. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that impurities such as residues clog the filtering equipment, resulting in a smaller water flow in sewage treatment and equipment such as water pumps being subjected to operating pressure, and to propose a modularly designed sewage deep treatment system.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a modularly designed sewage deep treatment system, including a primary treatment tank and a secondary treatment tank, a water pump is installed on the top of the secondary treatment tank, and delivery pipes are fixedly connected at both ends of the water pump, one of the delivery pipes is fixedly connected to the primary treatment tank, and the other delivery pipe is fixedly connected to the secondary treatment tank, a fixing frame is fixedly connected to the top of the primary treatment tank, and a filtering mechanism is installed at the center of the bottom of the fixing frame;

[0009] Preferably, the second sliding rod is slidably connected to the outer ring, and a baffle is fixedly connected to the top of the second sliding rod.

[0010] Preferably, a spring is sleeved on the top surface of the second sliding rod, and the spring is located between the baffle and the outer ring.

[0011] Preferably, a reduction motor is fixedly mounted on the top of the fixing frame, and an output end of the reduction motor is fixedly connected to a driving bevel gear.

[0012] Preferably, one side of the active bevel gear is meshingly connected with a driven bevel gear, and the driven bevel gear is fixedly connected to the outer wall of the rotating tube.

[0013] Preferably, two activated carbon filter plates are installed in sequence from top to bottom in the inner cavity of the secondary treatment tank, and a nozzle is installed on the top of the inner cavity of the secondary treatment tank.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0024] like Figure 1-4 As shown, the utility model provides a modularly designed sewage deep treatment system, including a primary treatment tank 1 and a secondary treatment tank 2, a water pump 5 is installed on the top of the secondary treatment tank 2, and delivery pipes 51 are fixedly connected at both ends of the water pump 5, one of the delivery pipes 51 is fixedly connected to the primary treatment tank 1, and the other delivery pipe 51 is fixedly connected to the secondary treatment tank 2, a fixing frame 3 is fixedly connected to the top of the primary treatment tank 1, and a filtering mechanism 4 is installed at the center of the bottom of the fixing frame 3;

[0025] The filtering mechanism 4 includes a first sliding rod 46 and a filter screen 47. The filter screen 47 is slidably connected to the first sliding rod 46, and the bottom of the first sliding rod 46 is fixedly connected to the primary filter tank. The top surface of the first sliding rod 46 is rotatably connected to a rotating sleeve 44, and the outer wall of the rotating sleeve 44 is fixedly connected to a cleaning brush 45. The top of the cleaning brush 45 is fixedly connected to a rotating plate 41, and the middle of the rotating plate 41 is fixedly connected to a rotating tube 43. The bottom of the rotating tube 43 is fixedly connected to a spray plate 42, and the top of the rotating tube 43 is rotatably connected to a water inlet pipe 421.

[0026] The specific configuration and function of this embodiment are described in detail below. As the amount of wastewater in the primary treatment tank 1 gradually increases, the filter screen 47 begins to float upward. Under the action of buoyancy, the filter screen 47 slides on the surface of the first slide bar 46, and the outer ring 471 slides upward on the surface of the second slide bar 48, thereby squeezing the spring 49 and causing it to begin to compress.

[0027] When the filter screen 47 moves upward and contacts the cleaning brush 45, the reduction motor starts to work, driving the active bevel gear 423 to rotate. This causes the driven bevel gear 422 to also start to rotate, thereby rotating the rotating tube 43. When the rotating tube 43 rotates, it drives the rotating plate 41 to rotate together, and rotates relative to the water inlet pipe 421, thereby ensuring normal water inflow to the water inlet pipe 421.

[0028] When the rotating plate 41 rotates, it drives the cleaning brush 45 to start rotating. The rotation of the cleaning brush 45 cleans the surface of the filter screen 47, which not only prevents the filter screen from being blocked, but also makes impurities gather together. At this time, the filter screen 47 floats on the water surface, which is convenient for processing. Example

[0029] like Figure 3-4 As shown, the side wall of the filter screen 47 is fixedly connected to an outer ring 471, and the inner side of the primary filter tank is fixedly connected to a second slide bar 48. The second slide bar 48 is slidably connected to the outer ring 471, and a baffle 481 is fixedly connected to the top of the second slide bar 48. A spring 49 is sleeved on the top surface of the second slide bar 48, and the spring 49 is located between the baffle 481 and the outer ring 471. A reduction motor 6 is fixedly installed on the top of the fixed frame 3, and a driving bevel gear 423 is fixedly connected to the output end of the reduction motor 6. A driven bevel gear 422 is meshedly connected to one side of the driving bevel gear 423, and the driven bevel gear 422 is fixedly connected to the outer wall of the rotating tube 43. Two activated carbon filter plates 21 are installed in sequence from top to bottom in the inner cavity of the secondary treatment tank 2, and a nozzle 22 is installed on the top of the inner cavity of the secondary treatment tank 2.

[0030] The effect achieved by the whole embodiment is that the filtered sewage is transported to the inside of the secondary treatment tank 2 by the water pump 5, and the sewage is evenly sprayed out through the nozzle 22. In this process, the two activated carbon filter plates 21 perform secondary treatment on the sewage.

[0031] When the sewage in the primary treatment tank 1 gradually decreases, the filter 47 will gradually move downward. Under the push of the spring 49, the filter 47 can be quickly reset to avoid being stuck on the top of the surface of the first slide bar 46 due to friction. At the same time, when the filter 47 moves upward, the outer ring 471 will also scrape the dirt on the inner wall of the primary treatment tank 1.

[0032] The method of use and working principle of the device are as follows: first, the water inlet pipe 421 is connected to the external wastewater pool, so that the wastewater flows into the inner side of the rotating sleeve 44 through the water inlet pipe 421 and is sprayed out through the spray plate 42. During the spraying process, the wastewater will be filtered through the filter screen 47 to remove large particles of impurities, etc., to prevent these impurities from clogging other filtering equipment or pipelines.

[0033] When the wastewater in the primary treatment tank 1 gradually increases, the filter screen 47 begins to float upward. Under the action of buoyancy, the filter screen 47 slides on the surface of the first slide bar 46, and the outer ring 471 slides upward on the surface of the second slide bar 48. This causes the outer ring 471 to squeeze the spring 49, causing it to begin to compress.

[0034] As the filter screen 47 moves upward, it contacts the cleaning brush 45. Subsequently, the reduction motor starts to work, driving the active bevel gear 423 to rotate. This causes the driven bevel gear 422 to also start to rotate, thereby rotating the rotating tube 43. When the rotating tube 43 rotates, it drives the rotating plate 41 to rotate together, and rotates relative to the water inlet pipe 421, thereby ensuring normal water inflow to the water inlet pipe 421.

[0035] When the rotating plate 41 rotates, it drives the cleaning brush 45 to rotate. When the cleaning brush 45 rotates, it cleans the surface of the filter screen 47 to prevent it from getting clogged. This also helps to gather impurities together. At this time, the filter screen 47 floats on the water surface, which is convenient for processing. The filtered sewage is transported to the inside of the secondary treatment tank 2 by the water pump 5, and the sewage is sprayed out by the nozzle 22. In this process, the sewage is subjected to secondary treatment by two activated carbon filter plates 21.

[0036] As the sewage inside the primary treatment tank 1 gradually decreases, the filter screen 47 will gradually move downward and quickly reset under the push of the spring 49 to prevent the filter screen 47 from being stuck at the top of the surface of the first slide bar 46 due to friction. When the filter screen 47 moves upward, it will also use the outer ring 471 to scrape off the dirt on the inner wall of the primary treatment tank 1.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
