Description

Technical Field

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

[0002] Sewage refers to water discharged from life and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. If it is water used in life, it contains more organic matter and is easier to treat. In some places with less sewage discharge, or in specific places such as factories, sewage will be collected in storage tanks and then treated uniformly.

[0003] The prior art (publication number: CN 216170618 U) discloses a sewage collection and storage tank, which comprises a tank body; a first partition and a second partition are horizontally arranged from top to bottom inside the tank body; a second cavity is formed between the first partition and the second partition, a first cavity is formed above the first partition, and a third cavity is formed below the second cavity; a first filter screen is arranged inside the first cavity, and a second filter screen is arranged inside the second cavity; a first water inlet trough and a second water inlet trough are arranged at intervals on the top of the tank body; a plurality of partition blocks are arranged at intervals on the inner bottom of the tank body; a first water pump is arranged on the outer wall of the tank body; a water inlet of the first water pump is connected to the second cavity; a first pipe is connected to the water outlet of the second cavity; the other end of the first pipe is connected to the second water inlet trough; the first filter screen and the second filter screen are shaped like a trapezoidal funnel;

[0004] Although the above patent sets a first filter to filter sewage, it has the following disadvantages: sewage flows to only one side of the filter through the first water inlet trough, which may cause impurities on the filter to concentrate on one side, increasing the risk of blockage and obstruction on that side, which may affect the filtering effect and slow down the sewage treatment speed, and it is impossible to automatically clean the impurities on the surface of the filter, which requires further improvement. For this reason, we propose a storage tank for sewage treatment. Utility Model Content

[0005] The main purpose of the utility model is to provide a storage tank for sewage treatment, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A storage tank for sewage treatment comprises a sewage tank, a drain valve pipe is inserted and connected to the middle part of the lower end of the sewage tank, a feeding component is provided at the upper end of the sewage tank, the feeding component extends into the sewage tank, a conveying component is inserted and connected to the right part of the outer surface of the sewage tank, a filter is provided inside the sewage tank, the lower end of the conveying component is connected to an impurity tank, the lower end of the filter is inserted and connected to an electric valve, and the electric valve extends into the conveying component.

[0008] Preferably, the feeding component includes a water inlet pipe, which is arranged in the middle of the upper end of the sewage tank, and the lower end of the water inlet pipe extends into the sewage tank and is connected to a hollow cylinder, and the lower end of the hollow cylinder is provided with a plurality of through holes distributed in a circular array, and the outer surface of the hollow cylinder is fixedly connected to the inner wall of the sewage tank.

[0012] Preferably, a plurality of support columns distributed in a circular array are installed at the lower end of the sewage tank, and an observation window is provided on the front of the outer surface of the sewage tank.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting the feeding components, the sewage can flow to different positions of the filter. When in use, the sewage is transported into the hollow cylinder through the water inlet pipe, and then flows out from multiple through holes, so that the sewage flows to different positions of the filter, avoiding the impurities on the filter to be concentrated on one side, reducing the risk of filter blockage and obstruction, and ensuring the filtering effect and sewage treatment speed;

[0024] like Figure 1-Figure 4 As shown, a storage tank for sewage treatment includes a sewage tank 1, a drain valve pipe 3 is inserted and connected to the middle part of the lower end of the sewage tank 1, a feeding component 7 is provided at the upper end of the sewage tank 1, and the feeding component 7 extends into the sewage tank 1, a conveying component 6 is inserted and connected to the right part of the outer surface of the sewage tank 1, a filter screen 9 is provided inside the sewage tank 1, and the filter screen 9 is funnel-shaped, the lower end of the conveying component 6 is connected to the impurity tank 4, the lower end of the filter screen 9 is inserted and connected to the electric valve 10, and the electric valve 10 extends into the conveying component 6.

[0025] When in use, the sewage is transported to the sewage tank 1 through the feeding component 7, so that the sewage flows evenly to the surface of the filter screen 9 and flows to different positions of the filter screen 9, avoiding the impurities on the filter screen 9 from being concentrated on one side, reducing the risk of clogging and blocking of the filter screen 9, ensuring the filtering effect and sewage treatment speed, and the filtered sewage flows to the bottom of the sewage tank 1 for temporary storage, and the sewage can be discharged by opening the drain valve pipe 3.

[0026] The feeding component 7 includes an inlet pipe 71, which is arranged in the middle of the upper end of the sewage tank 1. The inlet pipe 71 is L-shaped and is provided with a flange. The lower end of the inlet pipe 71 extends into the sewage tank 1 and is connected to a hollow cylinder 72. The lower end of the hollow cylinder 72 is provided with a plurality of through holes 73 distributed in a ring array. The outer surface of the hollow cylinder 72 is fixedly connected to the inner wall of the sewage tank 1. When in use, the sewage pipeline is connected to the inlet pipe 71, and the sewage flows into the hollow cylinder 72 through the inlet pipe 71, and then flows out from the plurality of through holes 73, so that the sewage flows to different positions of the filter screen 9. At the same time, the sewage flowing downward can push the impurities on the filter screen 9 to move downward, so that the impurities are accumulated at the bottom of the filter screen 9, which is convenient for the electric valve 10 to discharge the impurities.

[0027] After the filter screen 9 filters a certain amount of sewage, impurities will accumulate in the filter screen 9. In order to ensure the normal filtration of the filter screen 9, the electric valve 10 and the conveying component 6 cooperate to convey the filtered impurities. The specific structure is: the conveying component 6 includes a conveying pipe 61, which is inserted and connected to the sewage tank 1. A motor 62 is installed at the right end of the conveying pipe 61. A sewage pipe 64 is inserted and connected to the lower right part of the outer cylindrical surface of the conveying pipe 61. The output end of the motor 62 extends into the conveying pipe 61 and is transmission-connected with a spiral conveying blade 63. The lower end of the electric valve 10 extends into the conveying pipe 61. After a certain period of use, the electric valve 10 is opened to allow impurities on the filter screen 9 to fall into the conveying pipe 61, and the motor 62 is controlled to drive the spiral conveying blade 63 to rotate. The spiral conveying blade 63 drives the impurities to move to the right, and then enters the impurity tank 4 from the sewage pipe 64, so as to avoid impurities accumulating on the surface of the filter screen 9, thereby ensuring the normal filtration of the filter screen 9, reducing the number of manual cleaning of impurities on the filter screen 9, and reducing the labor of workers.

[0028] The impurity tank 4 is connected to the lower end of the sewage pipe 64, and a sewage valve pipe 5 is inserted and connected to the lower right end of the impurity tank 4. The impurity tank 4 is used to store large particles of impurities in sewage.
