Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte storage tanks, in particular to a liquid storage tank which enables a pump to have a self-priming function. Background Art

[0002] The electrolyte is prepared by dissolving electrolytes in water in a tank. The electrolyte can be added to the equipment using either a surface tank with a pump or an underground tank with a submersible pump or self-priming pump. The surface tank with a pump does not require a high pump, but the electrolyte inlet is located at the top of the tank, making it more difficult to add electrolyte to the tank. For underground tanks, the electrolyte inlet can be set flush with the ground or slightly above, making it relatively easy to add electrolyte to the tank. For large quantities, the workload for the loading worker is much lower than with the surface tank method. Furthermore, due to the performance limitations of the submersible pump, the lift cannot be very high. Therefore, the underground tank with a self-priming pump is more suitable for large-scale engineering projects.

[0003] Usually, there are no internal parts inside the storage tank of a self-priming tank pump. Every time the pump is stopped, a large amount of liquid in the storage tank will flow back into the underground tank, so the storage tank needs to be refilled with liquid every time the pump is started. If the device has strict requirements on liquid balance and the demand for liquid replenishment is low, it is easy to cause liquid imbalance in the device, increasing maintenance frequency and cost.

[0004] Therefore, there is an urgent need for a liquid storage tank that can reduce the backflow of liquid to the underground tank and enable the pump to have a self-priming function. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantage of the utility model more clear, the following will be described in detail to the technical scheme of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other implementation manners obtained by those skilled in the art without creative labor belong to the range of the utility model.

[0035] Embodiment 1, reference Figure 1 The utility model discloses a kind of liquid storage tanks for making pump have self-suction function, with pump 6 communication, comprising:

[0036] Storage tank 1, storage tank 1 is arranged on ground;

[0037] Partition 2, partition 2 is fixedly connected in storage tank 1, and with the bottom plate, side wall of storage tank 1 It is sealed to set;

[0038] Liquid inlet area 11, the first side of partition 2 and the bottom plate, side wall between storage tank 1 form liquid inlet area 11, liquid inlet area 11 With underground tank 3 under ground communication;

[0039] Liquid outlet area 12, the second side of partition 2 and the bottom plate, side wall between storage tank 1 form liquid outlet area 12, liquid outlet area 12 With pump 6 communication, liquid in liquid inlet area 11 From the top of partition 2 Flow into liquid outlet area 12 by the negative pressure generated by pump 6.

[0040] Generally, the inside of self-suction tank type self-suction pump is not provided with inner part, and after stopping the pump each time, more liquid in the storage tank will flow back to the underground tank, so that the pump needs to be refilled with liquid when starting, and if the device has strict liquid balance requirements and low liquid supplement demand, the device liquid imbalance is easy to occur, and the maintenance frequency and cost are increased. In the present application, the partition 2 is arranged in the storage tank 1, and the storage tank 1 is divided into the liquid inlet area 11 and the liquid outlet area 12 by the partition 2, wherein the liquid inlet area 11 is communicated with the underground tank 3 under the ground, and the liquid outlet area 12 is communicated with the pump 6. When the pump 6 is running, the liquid in the liquid outlet area 12 is output, a pressure driving the liquid in the liquid inlet area 11 is generated in the storage tank 1, the liquid in the liquid inlet area 11 overflows the partition 2 and enters the liquid outlet area 12, and the air above the liquid inlet area 11 and the liquid outlet area 12 is communicated above the partition 2. In this way, when the pump 6 stops running, the liquid capacity in the liquid outlet area 12 stops changing, the pressure generated by the output of the liquid outlet area 12 disappears in the storage tank 1, and the liquid in the liquid inlet area 11 stops entering the liquid outlet area 12. Due to the blocking effect of the partition 2, the liquid in the liquid inlet area 11 flows back to the underground tank 3, the liquid in the liquid outlet area 12 is retained, the situation of supplementing liquid to the liquid outlet area 12 when starting the pump 6 again is effectively avoided, the working efficiency is improved, and the maintenance frequency and cost are reduced.

[0041] Further optimization scheme, still include:

[0042] Liquid inlet 9, liquid inlet 9 is opened on the side wall of storage tank 1, underground tank 3 is communicated with liquid inlet area 11 through liquid inlet 9;

[0046] The water replenishing valve 5 is fixedly connected with the top of the storage tank 1 and is arranged correspondingly to the liquid outlet area 12.

[0047] The vent valve 4 is fixedly connected with the top of the storage tank 1.

[0048] Before the pump 6 is started for the first time, the water replenishing valve 5 and the vent valve 4 are opened, liquid is replenished into the liquid outlet area 12 through the water replenishing valve 5, and the amount of liquid added is determined by the liquid level meter on the storage tank 1; when the liquid is continuously replenished in the storage tank 1, in order to avoid that the gas in the storage tank 1 is compressed, the air is discharged through the vent valve 4 and discharged to the atmosphere after treatment; with the intermittent start of the pump 6 and the backflow of the liquid in the liquid inlet area 11, the gas in the storage tank 1 gradually increases, so that the liquid level in the liquid outlet area 12 gradually decreases after the pump 6 is started and stopped for a period of time; when the liquid level decreases to a specified range, the water replenishing valve 5 and the vent valve 4 are opened again to replenish liquid.

[0049] Further optimization scheme, also includes:

[0050] The liquid inlet area emptying valve 7 is fixedly connected with the bottom of the liquid inlet area 11 in the storage tank 1 and is located below the liquid inlet 9.

[0051] The liquid outlet area emptying valve 8 is fixedly connected with the bottom of the liquid outlet area 12 in the storage tank 1 and is located below the liquid outlet 10.
