Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a full-pipe-flow intelligent negative-pressure collection system. Background Art
[0002] With the improvement of rural living standards, the water consumption has increased significantly, resulting in an increase in domestic sewage volume. In order to better collect a large amount of domestic sewage, generally, the existing domestic sewage collection uses a negative-pressure collection system. The negative-pressure collection system includes a negative-pressure well, a negative-pressure pipe network, a negative-pressure station, and an intelligent monitoring platform. The negative-pressure pipe network generates negative pressure through the negative-pressure station to provide power for sewage transmission, so that the sewage is sucked into the pipe network under the action of negative pressure and transmitted to the terminal treatment equipment for treatment to meet the discharge standard or reuse requirements. Through remote monitoring of the intelligent monitoring platform, the operation status of the pipeline and the sewage collection situation can be monitored in real time, and faults can be discovered and processed in time. The negative-pressure pipe network generates a negative-pressure state through the negative-pressure station, enabling the sewage to fill the pipe cross-section to form a full-pipe flow. In the full-pipe flow state, the flow velocity distribution of the sewage in the pipe is uniform and the flow is stable, which is conducive to the efficient collection and treatment of sewage.
[0003] The collected sewage is stored in the vacuum tank of the negative-pressure station. When the water level detector in the vacuum tank detects that the liquid level reaches the high level, the water level detector will control the sewage pump to start automatically, pumping the sewage out of the vacuum tank and transporting it to the terminal sewage treatment equipment or the municipal sewage pipe network through the pipeline. However, when the system is continuously in the full-pipe flow state, the amount of sewage that the terminal sewage treatment equipment needs to process will increase correspondingly, which may exceed its treatment capacity range, resulting in a decline in treatment effect or equipment damage. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a full-pipe-flow intelligent negative-pressure collection system.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A full-pipe-flow intelligent negative-pressure collection system includes a negative-pressure well, a negative-pressure pipe network, and a negative-pressure station. The negative-pressure pipe network connects the negative-pressure well and the negative-pressure station. The negative-pressure station includes a vacuum tank, a vacuum pump connected to the vacuum tank through a pipeline, and a sewage pump for transporting the sewage in the vacuum tank to the sewage treatment equipment. The vacuum tank includes a suction pipe connected to the sewage pump and a water level detector I for detecting the high water level in the vacuum tank. The water level detector I is signal-connected to the sewage pump to control the sewage pump to start.
[0007] The negative pressure station is provided with a shunt box for storing sewage and a shunt pipe communicated with a suction pipe. The shunt pipe is communicated with the shunt box. A water level detector II for detecting the low water level in the shunt box is installed in the shunt box. The water level detector II is signal-connected to a sewage pump for controlling the sewage pump to close. A drain valve I signal-connected to the water level detector I is installed on the suction pipe.
[0008] It is further set that a filter plate is installed in the shunt box. The filter plate divides the internal space of the shunt box into a water inlet area and a water outlet area. A first branch pipe and a second branch pipe respectively communicated with the water inlet area and the water outlet area are communicated with the shunt pipe. A drain valve II signal-connected to the water level detector I is installed on the first branch pipe. A drain valve III signal-connected to the water level detector I is installed on the second branch pipe. The water level detector II is placed in the water outlet area.
[0009] It is further set that a V-shaped filter mesh sheet is arranged in the water inlet area. The first branch pipe corresponds to the filter mesh sheet. The filter mesh sheet is installed on the filter plate. A fixing block is installed on the filter mesh sheet. The fixing block is installed on the inner wall of the shunt box through screws.
[0010] It is further set that a connecting block is installed on the filter plate. A guiding groove for sliding connection with the connecting block is installed on the inner wall of the shunt box. The guiding groove is L-shaped.
[0011] By adopting the above technical solutions, the beneficial effects of the utility model are as follows: When the system is continuously in a full pipe flow state, the sewage volume flowing to the sewage treatment equipment at the terminal can be shunted, thereby reducing the sewage volume flowing to the sewage treatment equipment, relieving the working pressure of the sewage treatment equipment, and preventing the sewage volume from flowing to the sewage treatment equipment too much in a certain period of time and exceeding its treatment capacity range, resulting in a decline in treatment effect or equipment damage.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Reference Figures 1 to 3 A further description is made for the embodiments of the present utility model.
[0017] A full-pipe flow intelligent negative pressure collection system includes a negative pressure well 01, a negative pressure pipe network 02 and a negative pressure station 03. The negative pressure pipe network 02 connects the negative pressure well 01 and the negative pressure station 03. The negative pressure station 03 includes a vacuum tank 1, a vacuum pump 2 connected to the vacuum tank 1 through a pipeline, and a sewage pump 3 for transporting the sewage in the vacuum tank 1 to a sewage treatment device. The vacuum tank 1 includes a suction pipe 4 connected to the sewage pump 3 and a water level detector 5 for detecting the high water level in the vacuum tank 1. The water level detector 5 is signal-connected to the sewage pump 3 to control the opening of the sewage pump 3.
[0018] A shunt box 6 for storing sewage and a shunt pipe 7 connected to the suction pipe 4 are provided in the negative pressure station 03. The shunt pipe 7 is connected to the shunt box 6. A water level detector 8 for detecting the low water level in the shunt box 6 is installed in the shunt box 6. The water level detector 8 is signal-connected to the sewage pump 3 to control the closing of the sewage pump 3. A drain valve 9 signal-connected to the water level detector 5 is installed on the suction pipe 4.
[0019] Working principle: When the system is continuously in a full-pipe flow state, the amount of sewage in the vacuum tank 1 gradually increases and quickly reaches the high water level state. At this time, the water level detector 5 sends a signal to control the sewage pump 3 to start working and control the drain valve 9 to open. The sewage pump 3 pumps out the sewage in the vacuum tank 1 through the suction pipe 4 and transports it to the terminal sewage treatment device. During this process, a part of the sewage in the suction pipe 4 will flow into the shunt pipe 7 and enter the shunt box 6 for storage, so that the water level in the vacuum tank 1 quickly drops to a safe height. At this time, the water level detector 5 controls the drain valve 9 to close, and the sewage pump 3 continues to work to pump out the sewage in the shunt box 6 through the suction pipe 4 and the shunt pipe 7 connected to the suction pipe 4 and transports it to the terminal sewage treatment device for treatment. When the water level detector 8 detects that the water level in the shunt box 6 is in the low water level state, the water level detector 8 sends a signal to control the sewage pump 3 to close, so that the sewage pump 3 stops transporting sewage to the sewage treatment device, realizing the shunting of the amount of sewage flowing to the terminal sewage treatment device and thus reducing the amount of sewage flowing to the sewage treatment device, relieving the working pressure of the sewage treatment device, and preventing the sewage treatment effect from decreasing or the equipment from being damaged due to the excessive amount of sewage flowing to the sewage treatment device beyond its treatment capacity range during a certain period of time.
[0020] A filter plate 601 is installed in the flow splitting box 6. The filter plate 601 divides the internal space of the flow splitting box 6 into a water inlet area 18 and a water outlet area 19. The flow splitting pipe 7 is communicated with a first branch pipe 10 and a second branch pipe 11 which are respectively communicated with the water inlet area 18 and the water outlet area 19. A drain valve two 12 which is signal-connected to the water level detector one 5 is installed on the first branch pipe 10, and a drain valve three 13 which is signal-connected to the water level detector one 5 is installed on the second branch pipe 11. The water level detector two 8 is placed in the water outlet area 19.
[0021] When the drain valve one 9 is opened, the water level detector one 5 controls the drain valve two 12 to open and controls the drain valve three 13 to be in a closed state, so that the sewage entering the flow splitting pipe 7 enters the water inlet area 18 in the flow splitting box 6 through the first branch pipe 10. The sewage in the water inlet area 18 is preliminarily filtered by the filter plate 601 and then flows into the water outlet area 19 through the filter holes on the filter plate 601. When the drain valve one 9 is closed, the water level detector one 5 controls the drain valve two 12 to close and controls the drain valve three 13 to be in an open state, which is convenient for the sewage pump 3 to pump out the sewage preliminarily filtered by the filter plate 601 in the water outlet area 19 through the flow splitting pipe 7 and the second branch pipe 11 and transport it to the terminal sewage treatment equipment for treatment. The sewage in the flow splitting box 6 is preliminarily filtered by the filter plate 601 to reduce the treatment burden of the terminal sewage treatment equipment and further avoid equipment damage.
[0022] A V-shaped filter mesh sheet 14 is arranged in the water inlet area 18. The first branch pipe 10 corresponds to the filter mesh sheet 14. Due to the possible peculiar smell of the sewage entering the water inlet area 18, the upper part of the water inlet area 18 is in a closed state to reduce the emission of the sewage peculiar smell. The filter mesh sheet 14 roughly filters the sewage entering the water inlet area 18, and the V-shaped filter mesh sheet 14 filters the sewage better. The filter plate 601 further filters to improve the sewage filtering effect and further reduce the treatment burden of the terminal sewage treatment equipment. Moreover, the filter mesh sheet 14 is installed on the filter plate 601, and a fixing block 15 is installed on the filter mesh sheet 14. The fixing block 15 is installed on the inner wall of the flow splitting box 6 by screws, so that the filter mesh sheet 14 is stably installed in the water inlet area 18 and can be used normally, with high practicability.
[0023] A connecting block 16 is installed on the filter plate 601. A guiding groove 17 which is slidably connected with the connecting block 16 is installed on the inner wall of the flow splitting box 6. The guiding groove 17 is L-shaped. Remove the screws on the fixing block 15 and slide the connecting block 16 on the filter plate 601 in the guiding groove 17 to move the filter plate 601 to the water outlet area 19. Cooperating with the L-shaped guiding groove 17, the filter plate 601 is slid upward, so as to take out the filter plate 601 and the filter mesh sheet 14 thereon from the flow splitting box 6 for cleaning, which is convenient for continuously filtering the sewage entering the flow splitting box 6 in the future, thereby continuously reducing the treatment burden of the terminal sewage treatment equipment.
[0024] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model shall be included within the protection scope of the present utility model.
