Description

Technical Field

[0001] The utility model relates to the field of production equipment for hard carbon negative electrode materials, and particularly relates to a constant-pressure water supply system for a hard carbon negative electrode production line. Background Art

[0002] Before pre-carbonization, hard carbon raw materials need to be cleaned to ensure that there are fewer impurities in the raw materials. Traditional operators usually pressurize tap water and then carry out cleaning. However, pressurization cannot ensure that the water pressure remains constant during the cleaning process for two reasons: First, the water pressure of tap water cannot be guaranteed, and unstable factors often occur due to pipeline rupture. Second, the pressurization equipment uses a water pump. Once the water supply of the water pump is insufficient or fluctuates, the water pressure during the cleaning process cannot be guaranteed either. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem of incomplete cleaning caused by unstable water pressure during the process of cleaning hard carbon raw materials.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A constant-pressure water supply system for a hard carbon negative electrode production line includes a water tank, a baffle, a water inlet pipe, a connecting pipe, a frequency conversion controller, a constant-pressure output mechanism, and a constant-pressure water storage tank. The middle of the water tank is divided into upper and lower parts by the baffle. The upper part is used for storing water, and the lower part is for pressurization. The constant-pressure output mechanism is arranged inside the bottom of the baffle. The constant-pressure output mechanism is communicated with the upper part of the baffle through the connecting pipe. The frequency conversion controller is installed on one side of the water tank, and the frequency conversion controller is electrically connected with the constant-pressure output mechanism. The constant-pressure water storage tank is installed at one end of the water tank through a support frame, and the output end of the constant-pressure output mechanism is communicated with the constant-pressure water storage tank.

[0006] Preferably, a filter is arranged at one end of the water inlet pipe extending into the water tank, and a first solenoid valve is further arranged on the connecting pipe. The first solenoid valve is electrically connected with the frequency conversion controller.

[0007] Preferably, a ventilation window is further opened on one side of the water tank, and the ventilation window and the frequency conversion controller are on the same side of the water tank.

[0008] Preferably, the constant-pressure output mechanism includes a flow stabilizer, a first delivery pipe, a first pressurizing water pump, a second pressurizing water pump, a second solenoid valve, a third solenoid valve, and a second delivery pipe. The input end of the flow stabilizer is communicated with the connecting pipe, and the output end is connected with the first delivery pipe. The first pressurizing water pump and the second pressurizing water pump are respectively connected with the first delivery pipe. The output ends of the first pressurizing water pump and the second pressurizing water pump are respectively connected with the second delivery pipe through the second solenoid valve and the third solenoid valve. The output end of the second delivery pipe is communicated with the bottom of the constant-pressure water storage tank through a water storage pipeline.

[0009] Preferably, the flow stabilizer, the first booster pump, the second booster pump, the second solenoid valve, and the third solenoid valve are electrically connected to the frequency conversion controller respectively.

[0010] Preferably, a negative pressure suppressor and a first pressure valve are further provided on the flow stabilizer, and the negative pressure suppressor and the first pressure valve are also electrically connected to the frequency conversion controller.

[0011] Preferably, a second pressure valve and a fourth solenoid valve are further provided on the second delivery pipe, and the second pressure valve is located at the front end of the fourth solenoid valve. The second pressure valve and the fourth solenoid valve are also connected to the frequency conversion controller.

[0012] Preferably, one side of the water storage pipeline is also connected to a drainage pipeline, a fifth solenoid valve is provided on the drainage pipeline, and the fifth solenoid valve is also electrically connected to the frequency conversion controller.

[0013] Working principle:

[0014] Tap water is introduced into the water storage part through the water inlet pipe by an external water pump. When constant pressure water is needed, the frequency conversion controller sends an instruction to open the first solenoid valve. At the same time, the flow stabilizer receives the instruction from the frequency conversion controller and introduces the tap water in the upper part into the interior. The flow stabilizer mainly ensures the stable flow of tap water, and then the first booster pump and the second booster pump pressurize the tap water with stable water pressure. The pressurization intensity is controlled by the frequency conversion controller. When the tap water is pressurized to the specified pressure, the second pressure valve mainly feeds back the pressurized pressure value to the frequency conversion controller, and then the tap water with constant pressure flows through the fourth solenoid valve to the constant pressure water storage tank. When it is necessary to clean the raw materials, only need to open the fifth solenoid valve, and at this time the constant pressure water flows out through the drainage pipeline.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. The flow stabilizer enables the unstable tap water to flow stably at a certain pressure. Secondly, when the internal pressure of the flow stabilizer is unstable, the frequency conversion controller makes the negative pressure suppressor work to supplement the external pressure, so that the water pressure flowing into the first booster pump and the second booster pump is constant.

[0017] 2. The frequency conversion controller controls the opening and closing of the fourth solenoid valve according to the pressure feedback by the second pressure valve, and stores the constant pressure water in the constant pressure water storage tank. When water is needed, the fourth solenoid valve is closed and the fifth solenoid valve is opened at the same time, thereby ensuring that the water pressure remains constant during the cleaning operation.

The middle of the water tank 1 is divided into upper and lower parts by the baffle 2. The upper part is used for storing water, and the lower part is used for pressurization. Pressurization means pressurizing tap water at normal pressure to a certain pressure. The constant - pressure output mechanism 6 is arranged inside the bottom of the baffle 2. The constant - pressure output mechanism 6 is communicated with the upper part of the baffle 2 through the connecting pipe 4. The frequency - conversion controller 5 is installed on one side of the water tank 1, and the frequency - conversion controller 5 is electrically connected to the constant - pressure output mechanism 6. The constant - pressure water storage tank 7 is installed at one end of the water tank 1 through the support frame 8.

[0025] One end of the water inlet pipe 3 extending into the water tank 1 is provided with a filter 9, and the filter 9 is mainly used for filtering. A first solenoid valve 10 is also arranged on the connecting pipe 4. The first solenoid valve 10 is electrically connected to the frequency - conversion controller 5, and the flow of water is controlled through the first solenoid valve 10.

The ventilation hole 11 is mainly provided to enable the negative pressure suppressor 13 to work properly.

[0027] The constant pressure output mechanism 6 includes a flow stabilizer 60, a first delivery pipe 61, a first pressurizing water pump 62, a second pressurizing water pump 63, a second solenoid valve 64, a third solenoid valve 65 and a second delivery pipe 66.

[0029] Working process:

[0030] Tap water is introduced into the water storage part through the water inlet pipe 3 by an external water pump.

At the same time, the flow stabilizer 60 receives the instruction from the frequency conversion controller 5 and introduces the tap water in the upper part into it.

Then, the tap water with a stable water pressure is pressurized by the first pressurizing water pump 62 and the second pressurizing water pump 63, and the pressurizing intensity is controlled by the frequency conversion controller 5. When the tap water is pressurized to the specified pressure, the second pressure valve 15 mainly feeds back the pressurized pressure value to the frequency conversion controller 5, and then the tap water with a constant pressure flows to the constant pressure water storage tank 7 through the fourth solenoid valve 16. When the raw materials need to be cleaned, the fourth solenoid valve 16 is closed and the fifth solenoid valve 18 is opened. At this time, the constant pressure water flows out through the drainage pipeline.
