Description

Technical Field

[0001] The utility model belongs to the technical field of sewage filters, and specifically relates to a sewage filter with a shunt discharge function. Background Technique

[0002] Sewage refers to the discharged water from life and production that is contaminated to a certain extent, and the water that has lost its original use function is simply called sewage. In order to protect the environment and human health, it is necessary to treat sewage so that it meets the environmental discharge standards or reuse requirements. A sewage filter is a key environmental protection device used to remove impurities and pollutants in sewage to ensure that the water quality meets national standards.

[0003] The utility model with the publication number CN211419804U discloses a sewage filter with a shunt discharge function, including a housing and a driving motor. A purification box is fixedly connected to the inner top of the housing. The top of the purification box is connected with a liquid inlet hopper, and the top of the liquid inlet hopper penetrates through the top of the housing and extends upward. A stirring mechanism is arranged in the purification box. A liquid outlet pipe is connected to the bottom of the purification box. A switching mechanism is arranged on one side of the liquid outlet pipe. A filter screen is arranged at the lower end of the liquid outlet pipe. Both sides of the filter screen are connected to the inner wall of the housing through a clamping mechanism. A collection box fixedly connected to the inner bottom of the housing is arranged below the filter screen.

[0004] During the implementation of this application, it is found that there are the following problems in this technology: when treating sewage in the above patent document, the sewage is directly discharged from the liquid inlet hopper into the purification box in the housing, and the stirring mechanism is used to stir it so that the flocculant polymerizes with the impurities in the sewage to form flocs and then purifies. However, in the application, the sewage is directly discharged into the box body. There are often some large solid impurities in the sewage, such as sand, gravel, metal particles, and plastic particles. These large impurities directly entering the purification box may damage the stirring mechanism; at the same time, the sewage also contains some long and thin fibrous garbage, such as hair, textile fibers, and other plant fibers. These impurities entering the box body may entangle on the stirring mechanism, affecting the treatment of sewage by the stirring mechanism.

[0005] Therefore, a sewage filter with a shunt discharge function is proposed. Content of the Utility Model

[0006] The purpose of the utility model is: in order to clean the large solid impurities in the sewage in advance, avoid these large solid impurities directly entering the interior of the filter box body and affecting the stirring of the stirring mechanism, and improve the sewage treatment efficiency, this application provides a sewage filter with a shunt discharge function.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A sewage filter with a shunt discharge function, comprising a filter box body, a pretreatment mechanism, a filtering mechanism and a stirring mechanism. An inlet is provided on the upper surface of the filter box body. The pretreatment mechanism is arranged inside the inlet. The pretreatment mechanism includes an upper frame body. Two ends of the upper surface of the upper frame body are fixedly connected with carrying plates. The outer surface of the upper frame body is in close fit with the inner side wall of the inlet. The lower right inner wall of the upper frame body is fixedly connected with an inclined filter net. One end of the inclined filter net away from the right inner wall of the upper frame body is fixedly connected with an upper filter net. One end of the upper filter net away from the inclined filter net is fixedly connected with the lower left inner wall of the upper frame body;

[0009] The stirring mechanism includes a motor. The motor is fixedly connected to the outer wall on the right side of the filter box body. A rotating rod is installed at the output end of the motor. One end of the rotating rod away from the motor is rotatably connected to the left inner wall of the filter box body through a bearing. A plurality of stirring rods are fixedly connected to the outer surface of the rotating rod. Blades are fixedly connected to the outer surface of the rotating rod along the axial direction.

[0010] Further, a partition is fixedly connected to the middle of the inner side wall of the filter box body. A water guide pipe is installed in the middle of the lower surface of the partition. A solenoid valve is installed on the outer surface of the lower end of the water guide pipe.

[0011] Further, a U-shaped groove body is fixedly connected to the lower left inner wall of the filter box body.

[0012] Further, the filtering mechanism includes a lower frame body. A lower filter net is fixedly connected to the inner side wall of the lower frame body. The outer surface of the left end of the lower frame body is inserted into the inner surface of the U-shaped groove body. One end of the lower frame body away from the U-shaped groove body extends outside the filter box body and is then fixedly connected with a sealing plate. A handle is fixedly connected to the right side surface of the sealing plate.

[0013] Further, a rubber pad is adhered to the upper surface of the lower frame body.

[0014] Further, bottom columns are fixedly connected to both ends of the lower surface of the filter box body. The inner cavity at the bottom end of the filter box body communicates with a water outlet pipe. A valve is installed on the outer surface of the water outlet pipe. The inner bottom surface of the filter box body is inclined from the periphery to the upper end opening of the water outlet pipe.

[0016] 1. In the present utility model, when filtering sewage using the filter box body, the pretreatment mechanism is placed at the opening of the water inlet, and the bridging plate is lapped on the upper surface of the water inlet. When the sewage passes through the inclined filter screen and the upper filter screen, the inclined filter screen and the upper filter screen will intercept and filter the larger solid impurities in the sewage. Due to the inclined setting of the inclined filter screen, these larger solid impurities will gradually converge on the upper surface of the upper filter screen under the impact of the water flow, and will not directly accumulate at the inclined filter screen, preventing blockage, facilitating continuous filtering of the sewage, and also facilitating the staff to clean these larger solid impurities; through the cooperation of the above structures, the larger solid impurities in the sewage can be cleaned in advance, avoiding these larger solid impurities directly entering the interior of the filter box body and affecting the stirring of the stirring mechanism, and improving the sewage treatment efficiency.
