Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a reservoir for sewage treatment. Background Technique

[0002] A large amount of sewage will be generated during daily life and factory operations. Direct discharge will damage the ecological environment. Therefore, we need to purify the sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily life of ordinary people.

[0003] During the process of sewage treatment, a grid filter is often used. The grid filter operates driven by a motor. There will inevitably be garbage such as paper, cotton wool, and hair in the garbage. After being soaked, the adsorption force of such garbage increases, and it often adheres to the blades of the machine body and will not naturally fall into the garbage collection box, making it difficult to clean. Therefore, we propose a reservoir for sewage treatment. Content of the Utility Model

As the cleaning rod rotates, the spring in the sleeve will be compressed. At this time, the square rod will be pushed by the cam and then pass through the blades of the grid filter, effectively scraping off the garbage adsorbed on the blades of the grid filter, such as paper, cotton wool, and hair.

[0015] The present utility model is provided with a clamping rod. The clamping rod rotates synchronously with the cleaning rod driven by the motor.

[0030] Referring to Figure 4 , the double camshaft is composed of a cylindrical shaft, a cam group and a small cam group, the cylindrical shaft is rotationally connected to the motor to prevent the cylindrical shaft and the motor from rotating synchronously, the cam group and the small cam group are arranged on the cylindrical shaft, the cam group and the small cam group are alternately arranged on the cylindrical shaft, in order to correspond to the cleaning rod group and the clamping rod group one by one and ensure the movement trajectories of the cleaning rod group and the clamping rod group, a constant thrust is provided at the corresponding positions.

[0031] Referring to Figure 5 , the cleaning rod is composed of a square rod group, a sleeve group, a spring group and a ball group, the sleeve group is fixedly connected to the housing, the square rod is slidably connected to the sleeve, when the square rod makes a circumferential movement around the cam, as the radius of the cam changes, the square rod inside it will be pushed by the cam, pass through between the blades, and scrape the garbage attached to the blades of the grid filter, the spring is fixedly installed in the sleeve to provide a linear thrust for the reset of the square rod, the ball is rotatably connected to the square rod, and the ball group is in rolling contact with the cam group to reduce frictional damage.

[0032] Referring to Figure 6 , the clamping rod is composed of a convex rod group, a small sleeve group, a small spring group and a small ball group, the small sleeve group is fixedly connected to the housing, the convex rod is slidably connected to the small sleeve, when the convex rod makes a circumferential movement around the small cam, as the radius of the small cam changes, the convex rod will be pushed by the small cam, and after the square rod passes through the space between the blades, it will clamp the garbage carried by the cleaning rod group, the small spring is fixedly installed in the small sleeve, the small spring provides a thrust for the reset of the convex rod, the small ball is rotatably connected to the convex rod and is in rolling contact with the small cam to reduce frictional damage.

[0033] Referring to Figure 11, a sewage suction machine is installed in the primary sedimentation tank. The sewage suction machine consists of a suction mechanism, a sewage pumping pump, and a power source. The output end of the power source is fixedly connected to the suction mechanism. The power source drives the suction mechanism to rotate at the bottom of the primary sedimentation tank. The suction mechanism is used to suck the sediment at the bottom of the primary sedimentation tank to prevent excessive siltation in the primary sedimentation tank. A three-stage filtration system is fixedly installed in the secondary filtration tank. The three-stage filtration system further filters the supernatant of the primary sedimentation tank to make the filtered water quality meet the discharge standard. The first-stage filtration layer of the three-stage filtration system is conical in shape, preventing the supernatant pumped by the water pump from concentrating at one position for filtration, allowing the supernatant to flow to the entire surface of the filtration layer in a timely manner, and improving the utilization rate of the filtration layer.

[0034] Refer to Figure 3 , the sum of the lengths of the square rod and the ball is equal to the sum of the lengths of the convex rod and the small ball. The maximum radius of the cam is equal to the maximum radius of the small cam. In this way, when the square rod and the convex rod are pushed by the cam and squeeze the internal spring, it is ensured that the convex rod can extend the same length as the square rod. When the square rod leaves between the blades, the convex rod can effectively clamp it and prevent garbage from being left out.

[0035] Refer to Figures 2-4 , the maximum radii of the cam and the small cam, the length difference between the square rod and the sleeve, the length difference between the convex rod and the small sleeve, and the blade length of the grid filter are similar. In order to ensure the removal effect of the garbage attached to the blade as much as possible, and collect the garbage carried on the cleaning rod into the trash can as much as possible, and avoid garbage remaining on the blade and the blade cleaning device as much as possible.

[0036] Working principle: Sewage flows through the grid filter through the drainage channel. The blades of the grid filter carry large-volume garbage under the drive of the conveyor belt. Part of the garbage is directly thrown into the trash can. Some garbage such as paper scraps and cotton wool has strong adhesion after being soaked and still adheres to the blades. At this time, the motor will drive the housing to rotate, and the housing will drive the cleaning rod group and the clamping rod group to rotate around the double camshaft. The cam on the double camshaft will push the square rod to compress the spring, so that the square rod extends a distance equal to the blade length, scraping the garbage attached to the blade. Subsequently, the small cam will also push the convex rod to compress the spring, so that the convex rod extends and aligns with the square rod. The convex rod clamps the garbage carried on the square rod to prevent the garbage on the square rod from falling off the housing in advance, ensuring that the garbage attached to the square rod can also be recycled into the trash can. Subsequently, the sewage flows into the primary sedimentation tank. A suction mechanism is installed in the primary sedimentation tank. The suction mechanism can rotate around the bottom of the primary sedimentation tank under the drive of the power source, and suck the sediment settled at the bottom of the tank under the drive of the sewage pumping pump. Then the water pump pumps the supernatant in the primary sedimentation tank into the secondary filtration tank through the water pipe. A three-stage filtration system is installed in the secondary filtration tank. The first-stage filtration layer of the three-stage filtration system is conical in shape, improving the utilization rate of the filtration layer and preventing sewage from accumulating at the water outlet of the water pump.
