Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection, and particularly relates to a sewage treatment device with good sand removal effect. Background Technique

[0002] Environmental protection refers to protecting and improving the natural environment through various practical and administrative measures, preventing and controlling environmental pollution and damage, and maintaining ecological balance to ensure the survival and development environment of human beings. The importance of environmental protection lies in that it is directly related to human health, social and economic development, and the maintenance of the global ecological balance. With the acceleration of the industrialization process, environmental pollution and ecological damage problems have become increasingly prominent, seriously affecting human health and production and life. Therefore, strengthening environmental protection has become an urgent global task. In the process of environmental protection, it is necessary to treat sewage.

[0003] There is a sewage treatment device with the authorized publication number of CN216653737U, which includes an upper cylinder and a lower cylinder. The bottom of the lower cylinder is provided with feet. Flange connection parts are provided on both the upper cylinder and the lower cylinder and are connected by screws. A top cover is provided on the top of the upper cylinder. A rotating sieve barrel is penetrated through the top cover. A drain port is provided at the bottom of the lower cylinder. A filter screen and a filter layer are also provided in the lower cylinder. The filter screen is located above the filter layer. The bottom of the rotating sieve barrel is connected with a brush roller, and the brush roller is in contact with the upper surface of the filter screen. The purpose of the utility model is to provide a sewage treatment device, expecting to clean the filter screen while filtering to improve the filtering efficiency. However, the above sewage treatment device can only simply filter sewage through the filter screen. It is very difficult to completely remove particles such as sand and gravel carried in the sewage by only one filtration. Moreover, the device only treats sewage by filtration, and the treatment method is too simple. Therefore, it is necessary to provide a sewage treatment device with good sand removal effect to solve the above problems. Content of the Utility Model

[0004] The technical content of the utility model is to provide a sewage treatment device with good sand removal effect.

[0005] To solve the above problems, the present utility model provides a sewage treatment device with good sand removal effect, including a sand removal tank. The right side of the sand removal tank is connected to a water pump through a connecting pipe. A group of connecting pipes are installed on both sides of the water pump. The connecting pipe installed on the right side of the water pump is inserted and installed in a sedimentation tank. The sand removal tank and the sedimentation tank are symmetrically installed on the top of a fixing plate. Two groups of support plates are symmetrically installed at the bottom of the fixing plate. The water pump is installed on the top of a mounting plate, and the mounting plate is fixedly installed in the middle of the top of the fixing plate. Three filter plates are evenly inserted and installed inside the sand removal tank. The top of the filter plate passes through a through slot opened at the top of the sand removal tank and is installed with a pulling plate. Filter holes are opened on the filter plate. An insertion plate is installed at the bottom of the filter plate. Three slot plates are installed on the inner bottom surface of the sand removal tank. The insertion plate is inserted into a slot opened at the top of the slot plate. Four inclined blocks are installed on the inner bottom surface of the sand removal tank. Three sand discharge ports are opened on the front of the sand removal tank. A sealing plug is installed in each sand discharge port. A liquid inlet pipe is installed on the top of the sand removal tank. A filling pipe is installed on the top of the sedimentation tank. A motor is fixedly installed in the middle of the top of the sedimentation tank. A rotating shaft is installed at the bottom of the motor. The bottom of the rotating shaft is rotatably connected to the inner bottom surface of the sedimentation tank. A stirring device is installed on the rotating shaft. A liquid discharge pipe is installed at the right bottom of the sedimentation tank.

[0006] As a further solution of the present utility model, the length of the support plate is equivalent to the length of the fixing plate. The bottom of the support plate is provided with a T-shaped structure. A pipe cap is installed on the top of the liquid inlet pipe, which can be used to close the liquid inlet pipe.

[0007] As a further solution of the present utility model, the diameters of the filter holes opened on the three filter plates decrease sequentially from left to right. The pulling plate installed on the top of the filter plate is located at the top of the sand removal tank. Two handles are symmetrically installed on the top of the pulling plate, so as to pull the pulling plate and the filter plate out of the inside of the sand removal tank upward.

[0008] As a further solution of the present utility model, the three slot plates installed on the inner bottom surface of the sand removal tank are located between the four inclined blocks. One slot plate is located between two inclined blocks. The sand discharge ports opened on the front of the sand removal tank correspond to the three inclined blocks on the left side. The side of the inclined block close to the sand discharge port is the low side. The sealing plug is installed in the sand discharge port through a threaded structure. One side of the sealing plug is provided with a hexagonal structure, so as to facilitate the operator to rotate.

[0009] As a further solution of the present utility model, three stirring devices are evenly installed on the rotating shaft installed inside the sedimentation tank. Each stirring device is composed of eight stirring plates. A pipe cap is installed at the right end of the liquid discharge pipe, which can be used to close the liquid discharge pipe.

[0010] Compared with the related technologies, a sewage treatment device with good sand removal effect provided by the present utility model has the following beneficial effects:

[0011] 1. In the present utility model, three filter plates are inserted inside the sand removal tank. The diameters of the filter holes opened on the three filter plates decrease sequentially from left to right. After the sewage enters the inside of the sand removal tank through the liquid inlet pipe, the sewage can be filtered sequentially through the three filter plates, so as to block the particulate matters such as sand and stones in the sewage inside the sand removal tank. The sewage without a large amount of sand and stones is pumped into the sedimentation tank through a water pump for further sewage treatment process.

[0012] 2. In the present utility model, four inclined blocks are installed inside the sand removal tank. The sediment intercepted by the three filter plates in sequence will be concentrated in the top space of the inclined blocks between the three filter plates. The sand discharge port opened on the front of the sand removal tank corresponds to the three inclined blocks on the left side. The side of the inclined block close to the sand discharge port is the low side. Therefore, the sediment on the inclined block can be discharged through the sand discharge port, so as to realize the discharge of the sediment in the sand removal tank. The overall structure is compact and the operation is efficient and convenient.

[0013] 3. In the present utility model, a motor is installed on the top of the sedimentation tank. A rotating shaft is installed at the bottom of the motor, and a stirring device is installed on the rotating shaft. The sewage entering the sedimentation tank can be stirred through the stirring device. At the same time, a flocculant for precipitating the dissolved substances in the sewage can be added into the sedimentation tank through a dosing pipe installed on the top of the sedimentation tank. With the stirring of the stirring device, the flocculant can be fully mixed with the sewage, so as to promote the aggregation of the fine suspended particles in the sewage through chemical reaction to form larger flocs. Subsequently, the sewage is discharged from the sedimentation tank through a drain pipe, and the sewage can be further treated through sedimentation, filtration and other methods.
