Description

Technical Field

[0001] The utility model relates to the technical field of sewage disposal equipment, in particular to a regional sewage suction device. Background Technique

[0002] In the process of sewage treatment, a large amount of dirt will be deposited in the sewage treatment tank due to the sedimentation treatment of sewage. In order to better use the sewage treatment tank, it is necessary to clean the sewage treatment tank regularly. The cleaning work in the prior art is basically carried out by large gantry cranes or manual cleaning. Usually, a water pump is used as the power source to adsorb dirt. Each time the water pump is started, it needs to be manually exhausted before the water pump can continue to be used. If the water pump is started when there is air in it, it is easy to cause water hammer phenomenon, shortening the service life of the water pump. At the same time, the cost of using a water pump with automatic exhaust is higher. Content of the Utility Model

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0015] Please refer to Figure 1 , the regional sewage suction device of the present utility model is used for comprehensively discharging the bottom surface of the sewage pool. It includes a sewage suction component, a filtering component, and a water replenishing component. The sewage outlet of the sewage suction component is connected in a through manner to the filtering component, the water replenishing component is connected in a through manner to the sewage suction component, and the sewage suction component is used to discharge the dirt at the bottom of the sewage pool to the outside of the sewage pool. The filtering component filters the sewage extracted by the sewage suction component and discharges the filtered sewage. The water replenishing component is used to supplement clear water to the sewage suction component before the sewage suction component is started, discharge the air in the sewage suction component, and enable the sewage suction component to start smoothly and ensure the working efficiency of the sewage suction component.

[0016] The sewage suction component includes several sewage suction pipes 01 distributed on the bottom surface of the sewage tank. The total area that each sewage suction pipe 01 can suck sewage from is larger than the area of the bottom surface of the sewage tank, thus ensuring the purpose of cleaning all areas of the bottom surface of the sewage tank. The inlet of each sewage suction pipe 01 is located inside the sewage tank and is connected to the sewage source in a through manner. The outlets of the sewage suction pipes 01 are gathered into a collecting pipe 02 through pipelines. A water pump 05 is connected in a through manner at the sewage outlet of the collecting pipe 02, and the water outlet of the water pump 05 is connected to the filtering component in a through manner. The water replenishing component is connected to the collecting pipe 02 through a tee joint 04. When the water replenishing component works, it replenishes clear water to the water inlet of the water pump 05 to timely discharge the air in the water pump 05.

[0017] An electric ball valve 03 is installed on each sewage suction pipe 01, and the closing and opening of each electric ball valve 03 are controlled by an external controller. For example, there are 8 sewage suction pipes 01 arranged on the bottom surface of the sewage tank, which are named the first sewage suction pipe, the second sewage suction pipe, the third sewage suction pipe, and so on from top to bottom. When the first sewage suction pipe needs to suck sewage from the corresponding area at the bottom of the sewage tank, the controller starts the electric ball valve 03 on the first sewage suction pipe to open, and the electric ball valves 03 on the remaining 7 sewage suction pipes 01 are in the closed state. Similarly, when the second sewage suction pipe needs to suck sewage from the corresponding area at the bottom of the sewage tank, the controller starts the electric ball valve 03 on the second sewage suction pipe to open, and the electric ball valves 03 on the remaining 7 sewage suction pipes 01 are in the closed state.

[0018] If the first sewage suction pipe and the eighth sewage suction pipe need to suck sewage from the corresponding areas at the bottom of the sewage tank, the controller starts the electric ball valves 03 on the first sewage suction pipe and the eighth sewage suction pipe to open, and the electric ball valves 03 on the remaining 6 sewage suction pipes 01 are in the closed state. And so on to achieve comprehensive sewage discharge from the sewage tank.

[0019] It should be noted that the controller can also control several sewage suction pipes 01 to work in a cycle. For example, the working time of each sewage suction pipe 01 of the equipment is one hour. The controller opens the electric ball valve 03 on the first sewage suction pipe, and the electric ball valves 03 on the remaining 7 sewage suction pipes 01 are in the closed state. After the electric ball valve 03 on the first sewage suction pipe has been opened for one hour, the electric ball valve 03 on the first sewage suction pipe is closed, and the electric ball valve 03 on the second sewage suction pipe or any one of the remaining 7 sewage suction pipes 01 is opened. And so on. Thus, cyclic sewage suction from the bottom of the sewage tank is achieved. It should be noted that for those skilled in the art, controlling the start and stop of the electric ball valve 03 and the water pump 05 by the controller in the way of PLC or single-chip microcomputer belongs to the prior art.

[0020] The water replenishing component includes a water replenishing pipe 06 that is connected to the three-way pipe 04 in a through manner, and an electric ball valve 03 is provided on the water replenishing pipe 06. The opening and closing of the electric ball valve 03 are controlled by the above-mentioned controller. Before the water pump 05 in the sewage suction component starts, all the electric ball valves 03 on the sewage suction pipe 01 are in the closed state. The electric ball valve 03 on the water replenishing pipe 06 is opened through the controller to inject water into the water pump 05 so that all the air in the water pump 05 is discharged, and then the controller controls the water pump 05 to start and the electric ball valve 03 corresponding to the sewage suction pipe 01 to be opened. This avoids the "water hammer" phenomenon when the water pump 05 starts and improves the service life of the water pump 05. At the same time, the costs of the water pump 05, the electric ball valve 03, and the water replenishing pipe 06 are relatively lower than those of the automatic exhaust water pump 05.

[0021] The filtering component includes a filter 07 that is connected to the sewage outlet of the water pump 05 in a through manner. A pressure sensor is provided at the top of the filter 07, and a sewage discharge pipe 08 is provided at the bottom of the filter 07. An electric ball valve 03 is provided on the sewage discharge pipe 08. When the impurities in the filter 07 accumulate to a certain amount, the volume of the filter 07 becomes smaller, but the working efficiency of the water pump 05 remains unchanged, that is, the amount of sewage entering the filter 07 remains unchanged, resulting in an increase in the pressure inside the filter 07. When the pressure reaches the set value, the electric ball valve 03 on the sewage discharge pipe 08 is activated to discharge the impurities in the filter 07 through the collecting pipe 02, so that the pressure inside the filter 07 returns to the normal state.

[0022] It should be noted that, for the sake of clear description, the "electric ball valves" installed in different positions are identified with the same reference numeral "03".

[0023] If there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0024] The above embodiments are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
