In order to achieve the above purpose, the utility model adopts the following technical scheme:
the vacuum water diversion tank of the nickel electrolysis pit pump comprises a tank body, wherein the top of the tank body is provided with a water supplementing port and a float level meter mounting port, and the bottom of the tank body is provided with a sewage outlet; a water inlet is arranged above the side part of the tank body, and a first filter screen is arranged on the water inlet; a water outlet is arranged below the side part of the tank body, a second filter screen is arranged on the water outlet, and the mesh diameter of the second filter screen is smaller than that of the first filter screen.
Compared with the prior art, the utility model has the following beneficial effects:
the first filter screen and the second filter screen are arranged at the joint of the water inlet flange and the water outlet flange, so that the impurity content in the vacuum water diversion tank is reduced, and the blockage risk of the water pump is reduced; meanwhile, as the mesh diameter of the first filter screen is larger than that of the second filter screen, the liquid passing efficiency of the water inlet is ensured to be larger than that of the water outlet under the condition of the same pipe diameter, the filtering slag blocking is considered, the repeated water supplementing is avoided, and the running continuity of the vacuum water diversion system is improved.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
In the figure, a 1-tank body, a 2-water supplementing port, a 3-float liquid level meter mounting port, a 4-sewage draining port, a 5-water inlet, a 6-water outlet, a 7-first filter screen, an 8-second filter screen and a 9-liquid level observation window are arranged.
Detailed Description
The utility model is further explained below with reference to the drawings.
As shown in FIG. 1, the vacuum water diversion tank of the nickel electrolysis pit pump comprises a tank body 1, wherein the top of the tank body 1 is provided with a water supplementing port 2 and a float level gauge mounting port 3, and the bottom of the tank body 1 is provided with a sewage outlet 4; a water inlet 5 is arranged above the side part of the tank body 1, and a first filter screen 7 is arranged on the water inlet 5; a water outlet 6 is arranged below the side part of the tank body 1, a second filter screen 8 is arranged on the water outlet 6, and the mesh diameter of the second filter screen 8 is smaller than that of the first filter screen 7. The tank body 1 is also provided with a liquid level observation window 9, and the liquid level observation window 9 is provided with scales.
The working principle of the utility model is as follows: under the condition that parameters such as technical parameters, installation positions, structures and sizes of the original pit pump are kept unchanged, a vacuum water diversion tank is additionally arranged at the front end of an inlet of the pit pump, before the pump is started, water is filled into the vacuum water diversion tank and a pump cavity, after the pump is started, waste water in the vacuum water diversion tank is pumped first, vacuum is formed in the tank along with the decline of the liquid level in the tank, and when the pressure is lower than the atmospheric pressure of the liquid level of the pit, the waste water enters the vacuum water diversion tank along a water inlet pipe. When the liquid discharge of the pump and the liquid inlet of the suction pipeline reach balance, the liquid level in the vacuum water diversion tank is kept stable, namely a stable working state is achieved, and the waste water in the pit enters the vacuum water diversion tank along the suction pipe and is conveyed to the corresponding tank along with the operation of the pump.
When the novel vacuum water diversion tank is used, the novel vacuum water diversion tank is integrated into a centrifugal pump water pumping pipeline as required, water is injected to the highest water level line, and a float liquid level meter arranged in a float liquid level meter mounting port 3 and a water supplementing pipeline connected with a water supplementing port 2 are in linkage control through a DCS industrial control system; once the water level in the tank body 1 is lower than a designed lowest water level line (a lower triangle mark in the figure), the float liquid level meter sends a water supplementing signal to the DCS industrial control system, a water supplementing pipeline is automatically opened, and water is supplemented into the tank body 1 through the water supplementing port 2; when the water is replenished to the highest water line (triangle mark in the figure), the float liquid level meter sends a water stopping signal to the DCS industrial control system, and the water replenishing pipeline is automatically closed to stop replenishing water. In addition, when the floating ball liquid level meter breaks down, the water level in the tank body 1 can be observed through the liquid level observation window 9, and water is manually replenished, so that the water pumping operation is not influenced. The normal working water level of the vacuum water diversion tank is between the highest water level line and the lowest water level line.
When the centrifugal pump is started to pump water, large-particle impurities in the wastewater are filtered by the first filter screen 7 arranged on the water inlet 5, and only a small part of small-particle impurities enter the tank body 1, and the wastewater in the tank body 1 is filtered by the second filter screen 8 of the water outlet 6 to enter the centrifugal pump, so that the centrifugal pump is prevented from being blocked; the mesh diameter of the first filter screen 7 is larger than that of the second filter screen 8, so that the liquid passing efficiency of the water inlet is larger than that of the water outlet under the condition of the same pipe diameter, the filtering slag blocking is considered, the repeated water supplementing is avoided, and the running continuity of the vacuum water diversion system is improved. After the centrifugal pump stops pumping water, as the first filter screen 7 is arranged at the mouth of the water inlet pipe and is positioned under water, part of impurities in front of the first filter screen 7 fall back into the wastewater pool along with water flow, thereby avoiding the blockage of the first filter screen. If the first filter screen 7 and the second filter screen 8 are required to be cleaned and replaced, the connection parts of the pipeline flanges on the water inlet 5 and the water outlet 6 are only required to be opened, and the cleaning and replacement can be performed; compared with the traditional vacuum water diversion tank with the built-in filter cartridge, the vacuum water diversion tank shortens the maintenance time, facilitates the operation of post staff and reduces the labor intensity.
After long-time operation, if the vacuum water diversion tank needs to be cleaned, the vacuum water diversion tank can be cleaned by only opening the drain outlet 4 at the bottom of the tank body 1. After the cleaning is finished, the sewage outlet 4 is closed, and water is replenished to the highest water level line again.
