Abstract
The utility model discloses a kind of pump automatic flushing devices, including pump, the check-valves of cleansing medium, the inlet communication discharge tube of pump are set in the outlet of pump, the dynamic valve of pressure control switch, the outlet of dynamic valve and pump are provided on the discharge tube.The utility model passes through the outlet check-valves in pump, the inlet communication dynamic method in pump, the keying of pressure control check valve and dynamic valve when using pump operation, realize pump rear cleansing medium out of service automatically into pump, it is discharged automatically from discharge tube after completing cleaning, whole device is simple in structure, easy to implement, cleaning is at low cost, not labor intensive cost.
Description
Technical field
The utility model is related to chlor-alkali production apparatus field, especially a kind of pump automatic flushing device.
Background technology
In chlor-alkali production technique, the easily-crystallized stock of saturated brine etc, such material are usually conveyed using pump
After remaining in pump, since itself is easily crystallized, after pump is out of service, remaining easily-crystallized stock condenses in pump
Portion is easy the components such as the impeller inside stuck pump case, and next pump easily causes pump damage after starting, and is limited to pump
Internal structure is also more difficult to the cleaning inside pump.
Utility model content
Technical problem to be solved in the utility model is：A kind of pump automatic flushing device is provided, fortune can be stopped in pump
Pump is cleaned automatically after row.
Technical solution used by the utility model is to solve above-mentioned technical problem：Pump automatic flushing device, including
Pump, sets the check-valves of cleansing medium in the outlet of pump, the inlet communication discharge tube of pump, and band is arranged on the discharge tube
There are the dynamic valve of pressure control switch, the outlet of dynamic valve and pump.
It is further：The cleansing medium is pure water.
The utility model has the beneficial effects that：The utility model by outlet check-valves in pump, in the import of pump
It is connected to dynamic method, the keying of pressure control check valve and dynamic valve when using pump operation realizes that pump rear cleaning out of service is situated between
Matter is discharged after completing cleaning from discharge tube automatically automatically into pump, whole device is simple in structure, easy to implement, cleaning at
This is low, not labor intensive cost.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model；
In figure label for：1- pumps, 2- check-valves, 3- discharge tubes, 4- dynamic valves.
Specific implementation mode
The utility model is further detailed below in conjunction with the accompanying drawings for the ease of understanding the utility model,.
As shown in Figure 1, pump automatic flushing device described in the utility model, by being passed through cleansing medium pair into pump 1
It is cleaned inside pump 1, this cleaning process need to carry out after pump 1 is out of service, and in order to realize this process, the utility model
It is realized by the outlet check-valves 2 in pump 1, cleansing medium is built in check-valves 2, since check-valves 2 can only allow
Cleansing medium one-way movement, it is not necessary to worry that cleansing medium flows back, and the opening and closing of check-valves 2 is then by pumping caused by 1 self-operating
Pressure controls, and when pumping 1 operation, pumping 1 outlet, there are pressure, are naturally also pressed by this with the check-valves 2 of 1 outlet of pump
Power influences, and check-valves 2 is in closed state under the action of above-mentioned pressure, and cleansing medium cannot enter in pump 1, and once pump 1 and stop
It only runs, the pressure in 1 exit of pump disappears, and check-valves 2 is opened, and cleansing medium, which is entered by check-valves 2 in pump 1, to be cleaned.
The entrance of pump 1 is provided with discharge of the discharge tube 3 for cleansing medium, material will not be from row when in order to ensure 1 operation of pump
It puts in pipeline 3 and leaks out, need discharge tube 3 to be in closed state when pumping 1 operation, the opening and closing of this discharge tube 3 is then by being arranged
Dynamic valve 4 on discharge tube 3 controls, and dynamic valve 4 carries pressure control switch, then the opening and closing of dynamic valve 4 is also by 1 operation of pump
The pressure of generation controls, the outlet of dynamic valve 4 and pump 1, the pressure control switch under the action of, power when 1 operation of pump
Valve 4, which is pressurized, is in closed state, and after pump 1 is out of service, dynamic valve 4 is opened, and the cleansing medium for completing to clean in pump 1 then may be used
It is discharged from discharge tube 3.
It is a kind of easy crystalline material of saturated brine due to needing the crystallization cleaned in pump 1, so selecting pure water as cleaning
Medium, above-mentioned easy crystalline material, which is dissolved in pure water, facilitates discharge, can also save cleaning cost.
Claims (2)
