Description

Technical Field

[0001] The utility model belongs to the related technical field, and specifically relates to a transfer water tank system which is convenient for reducing the water body conveying pressure. Background Technique

[0002] A sludge dewatering machine is a device used in the fields of industrial production and environmental protection. Its main function is to separate water bodies or liquids containing sediment, so as to achieve the purpose of sludge dewatering. The working principle of the sludge dewatering machine usually involves physical separation and precipitation methods to separate sediment from the water body to achieve the sludge dewatering effect. The sludge dewatering machine generally consists of a feeding system, a separation system, and a slag discharging system. The feeding system conveys water bodies or liquids containing sediment into the separation system. The separation system separates and processes the sediment through a series of working devices and equipment. Finally, the slag discharging system processes and discharges the separated sediment.

[0003] Because the sludge dewatering machine is relatively tall, about ten meters high, the water pressure for supplying water to the sludge dewatering machine is relatively high. In this way, the output water pressure of the pump is very high, and the pipeline pressure of other equipment in the sewage treatment plant is also relatively high, making it easy to have pipeline rupture situations.

[0004] Improvements are made to solve the above problems, and specifically relate to a transfer water tank system which is convenient for reducing the water body conveying pressure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a transfer water tank system which is convenient for reducing the water body conveying pressure, so as to solve the problem in the above background technique that the sludge dewatering machine is relatively tall, about ten meters high, so the water pressure for supplying water to the sludge dewatering machine is relatively high, thus the output water pressure of the pump is very high, and the pipeline pressure of other equipment in the sewage treatment plant is also relatively high, making it easy to have pipeline rupture situations.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A transfer water tank system facilitating the reduction of water conveyance pressure, including a sludge dewatering machine device body and a slurry treatment tank disposed at the left end of the sludge dewatering machine device body; a chemical dosing mixing tank is disposed at the left end of the slurry treatment tank; a water pump 1 is disposed at the left end of the chemical dosing mixing tank, a transfer water tank is disposed at the left side of the water pump 1, a connection start solenoid valve and a water pump 2 are disposed at the left side of the transfer water tank, a connection floating plate is disposed inside the transfer water tank, a connection pulling rope is disposed at the upper end of the connection floating plate, a sensing controller is disposed at the upper end of the connection pulling rope, the sensing controller can control the start and stop of the connection start solenoid valve and the water pump 2. After the water pump 2 conveys water into the transfer water tank, the connection start solenoid valve closes. When the sludge dewatering machine device body needs water, the water pump 1 pumps water from the transfer water tank and conveys it to the sludge dewatering machine device body. When the water level in the transfer water tank drops to the critical point, the connection floating plate will pull the sensing controller to cause the connection start solenoid valve and the water pump 2 to start and open to inject water into the transfer water tank.

[0007] Preferably, a water suction pipe port and other equipment connection pipe ports are respectively disposed at the left side of the water pump 2. The water suction pipe port is connected to an external water supply point, and the other equipment connection pipe ports are used for connecting with other equipment.

[0008] Preferably, a ventilation hole is disposed at the upper side of the transfer water tank, and a connection resistance block is disposed on the inner side wall surface of the ventilation hole.

[0014] Compared with the prior art, the utility model provides a transfer water tank system which is convenient for reducing the water body conveying pressure, and has the following beneficial effects:

[0015] In the transfer water tank system which is convenient for reducing the water body conveying pressure, a transfer water tank is provided at the left side position of the water pump 1. A connecting starting solenoid valve and the water pump 2 are provided at the left side position of the transfer water tank. A connecting floating plate is arranged inside the transfer water tank. A connecting pull rope is arranged at the upper end position of the connecting floating plate. A sensing controller is arranged at the upper end position of the connecting pull rope. The sensing controller can control the start and stop of the connecting starting solenoid valve and the water pump 2. After the water pump 2 conveys water into the transfer water tank, the connecting starting solenoid valve is closed. When the sludge dewatering machine device body needs water, the water pump 1 pumps water from the transfer water tank and conveys it to the sludge dewatering machine device body. When the water level in the transfer water tank drops to the critical point, the connecting floating plate will pull the sensing controller to make the connecting starting solenoid valve and the water pump 2 start and open to inject water into the transfer water tank. After improvement, the output pressure of the water pump 2 is relatively small, and the pipe network water pressure of other equipment in the sewage treatment plant is greatly reduced, avoiding the rupture of the pipeline.

[0016] In the transfer water tank system which is convenient for reducing the water body conveying pressure, in order to keep the air pressure inside the transfer water tank balanced, there are air vents. However, the air vents are very easy to be frozen and blocked in winter, and it is very easy to cause the air pressure in the transfer water tank to decrease and then deform when pumping water. A freeze-proof and blockage prevention device body is provided at the position close to the left side of the transfer water tank. A lifting connection column is arranged at the middle position of the freeze-proof and blockage prevention device body. Lifting limit blocks are arranged at both sides of the lifting connection column. An auxiliary reset connection spring is arranged at the bottom side position of the lifting limit block. A middle-position moving contact metal sheet is arranged at the side position of the right lifting limit block. Contact metal sheets are arranged at the positions close to the upper and lower ends in the limit slot where the lifting limit block is located. The two contact metal sheets are respectively connected to the upper and lower ends of the connecting resistance block through wires. The middle-position moving contact metal sheet is connected to the middle of the connecting resistance block by a connecting wire. An internal power supply is arranged at the middle position of the wire. Moving the lifting connection column up or down will make the circuit form a path. After the path is formed, the connecting resistance block will be heated to melt the ice in the air vent so that the gas can enter smoothly, so that the transfer water tank can be kept balanced, and further effectively avoid the phenomenon that the water tank is deformed and damaged due to the air pressure caused by the ice blocking the air vent in winter.
