Description

Sewage pool impurity filtering structure and sewage plant inlet water sampling filtering device

Technical Field

The utility model relates to sewage treatment technology, in particular to an impurity filtering structure for a sewage pool and an inlet water sampling and filtering device for a sewage plant.

Background Art

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 care, and catering. When treating sewage, the existing sewage treatment plant will send the sewage into the sewage pool through the pumping equipment, sample and analyze the sewage, and then formulate the sewage treatment process. When sampling sewage, the sampling pipe will extend to a certain depth below the liquid surface of the sewage pool, and then the sewage will be extracted. However, when the sewage enters the sewage pool, it is not filtered, that is, the sewage pool contains a lot of garbage and impurities. In order to prevent garbage impurities from being sucked into the sampling water pipe, a filter is usually set at the sampling port to filter the garbage impurities. However, when sampling, because the water is pumped, a negative pressure will be formed around the sampling port, so the garbage impurities in the sewage will be sucked into the filter, and it is also easy to get stuck on the filter, affecting the sampling efficiency. In addition, when maintaining and cleaning the garbage and impurities on the filter, the sewage pool needs to be emptied before the operator can operate. This not only increases the difficulty of maintenance, but also affects the timeliness of sewage treatment.

Summary of the invention

In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is: how to provide a sewage pool impurity filtering structure that can conveniently clean garbage impurities on the filter tube underwater.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A sewage pool impurity filtering structure comprises two water storage tanks, wherein a water inlet pipe is vertically arranged in one of the water storage tanks, the lower end of the water inlet pipe is connected with the other water storage tank through a connecting pipe, a filter tube is arranged in the water inlet pipe on the same center line, filter holes are distributed on the tube body of the filter tube, the filter tube can slide and cooperate with the water inlet pipe along the center line direction of the water inlet pipe, a supporting boss is raised on the inner wall of the water inlet pipe and below the filter tube, a limiting cover plate for sealing the upper end of the filter tube is provided at the pipe mouth of the upper end of the filter tube, the limiting cover plate can abut against the pipe mouth of the water inlet pipe to limit the downward movement of the filter tube, springs abutting thereon are arranged between the supporting boss and the filter tube, when the spring is in a natural state, the upper tube body of the filter tube extends out of the water inlet pipe, when the filter tube compresses the spring, the limiting cover plate can abut against the pipe mouth of the water inlet pipe.

In the utility model, by continuously injecting sewage into the water tank where the water inlet pipe is located, the liquid level of the sewage in the water tank rises. When the liquid level floods the upper end of the water inlet pipe, it will enter the connecting pipe through the filter pipe and then flow to another water tank. After filtering through the filter holes on the filter pipe, the garbage impurities in the sewage will be adsorbed on the filter pipe. When the sewage is subsequently sampled, water can be taken from another filtered water tank. When a certain amount of garbage impurities are adsorbed on the filter net, the filter holes on the filter pipe will be blocked and need to be cleaned. The operator only needs to use a tool to squeeze the limit cover plate downward at the side of the water tank, that is, to move the filter pipe downward and squeeze and compress the spring. When the filter pipe moves downward, because the filter pipe and the water inlet pipe are in sliding cooperation, when the filter pipe is extended into the water inlet pipe, the upper end of the water inlet pipe will scrape off the garbage impurities adsorbed on the outer peripheral surface of the filter pipe. After the filter tube moves downward, it is reset by the spring. Through repeated operations on the filter tube, the garbage and impurities on the filter tube can be scraped off. In the process of continuous operation, the scraped garbage can be dispersed to a distance through the impact of water.

As an optimization, an outlet pipe is vertically arranged in the water storage tank located on one side of the water outlet direction of the connecting pipe, and the upper end of the outlet pipe is flush with the upper end of the inlet pipe. The end of the connecting pipe away from the inlet pipe extends into the water storage tank where the outlet pipe is located and is connected to the lower end of the outlet pipe. The connecting pipe is a downwardly curved arc pipe, and the bottom of the connecting pipe is connected to a drain pipe passing through the water storage tank and extending outside the water storage tank. The drain pipe is located outside the water storage tank and is equipped with a drain valve. The inlet pipe, the outlet pipe and the connecting pipe of the arc pipe structure form a U-shaped structure as a whole, so that even if some sludge can pass through the filter tube, it will be deposited in the connecting pipe to avoid entering the next-level water storage tank. Open the drain valve regularly to flush the connecting pipe to rinse the impurities in the sludge.

As an optimization, an internal threaded tube coaxial with the filter tube is fixedly connected to the top surface of the limit cover plate, an operating rod is vertically arranged above the internal threaded tube, the lower end of the operating rod is threadedly connected to the internal threaded tube, the upper end of the operating rod extends out of the water tank, and a handle is fixedly connected to the upper end of the operating rod, so that the operator can operate above the water tank conveniently.

As an optimization, a sewage pipe is connected to the bottom of the water storage tank, and a sewage valve is installed on the sewage pipe. The sewage in the water storage tank can be emptied for cleaning through the sewage valve.

The utility model also discloses a sewage plant water inlet sampling and filtering device, including a plurality of water storage tanks connected in sequence, the first water storage tank is provided with a sewage inlet pipe for injecting water therein, the last water storage tank is provided with a water pumping pipe capable of pumping water outward, the sewage tank impurity filtering structure as described above is adopted between two adjacent water storage tanks, the aperture of the filter hole on the filter tube in the upper water storage tank is larger than the aperture of the filter hole on the filter tube in the lower water storage tank. In the utility model, sewage enters the first water storage tank, and garbage of different sizes is filtered in sequence through the filtering structure between the plurality of water storage tanks, so that sampling is performed in the last water storage tank, which can avoid the garbage impurities from affecting the sampled water quality.

Compared with the prior art, the utility model has the following advantages: the utility model can filter out garbage impurities in sewage, and can remove impurities on the filter structure during the use of the water storage tank, thereby reducing the impact on sewage detection results.
