[0013] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0014] The technical solution specifically implemented in this utility model is:

[0015] like Figure 1 and Figure 2 As shown, a double-discharge liquid suction filter includes a tank body 1, the upper part of the tank body 1 is connected to a high-pressure fan 2 and a filter barrel 4, the upper part of the filter barrel 4 is connected to a suction port 5, the tank body 1 is provided with a pressure discharge port 6, the bottom of the tank body 1 is provided with a gravity discharge port 7, the horizontal height of the pressure discharge port 6 is higher than the gravity discharge port 7, and the suction port 5, the pressure discharge port 6 and the gravity discharge port 7 are all provided with a manual valve 8.

[0016] The filter barrel 4 is provided with a detachable filter screen barrel 9, the upper part of the filter screen barrel 9 is provided with an outwardly protruding mounting edge 10, the inner wall of the filter barrel 4 is provided with a corresponding mounting boss 11, the mounting edge 10 is snapped onto the mounting boss 11, and the filter screen barrel 9 matches the inner cavity of the filter barrel 4; during specific use, when the suction force becomes smaller, it is convenient to separate the filter barrel 4 from the filter screen barrel 9, clean the impurities in the filter screen barrel 9, and restore the filtering capacity of the filter barrel.

[0017] The high-pressure fan 2 is connected to a motor 3, and the motor 3 is fixedly arranged on the tank body 1. The high-pressure fan 2 is connected to the tank body 1 through a hose 15, and the high-pressure fan 2 is provided with an exhaust port 16 and an air filling port 17 matching the hose 15; specifically, during the liquid extraction process, the exhaust port 16 of the high-pressure fan 2 is connected to the tank body 1 through the hose 15, so that the high-pressure fan can extract the air in the tank body 1 to generate a negative pressure in the tank body 1; during the pressure discharge process, the hose 15 needs to be switched to the air filling port 17, and the air filling port 17 of the high-pressure fan 2 is connected to the tank body 1 through the hose 15, so that the high-pressure fan can fill air into the tank body 1 to generate a positive pressure in the tank body 1.

[0018] The tank body 1 is provided with a liquid level detection switch 12, and the signal of the liquid level detection switch 12 is connected to the motor 3; during specific use, when the liquid level in the tank body 1 reaches a high level, the liquid level detection switch 12 will send a signal to the motor 3, the motor 3 will be turned off, and the high-pressure fan 2 will stop working to prevent the liquid in the tank body 1 from exceeding the capacity.

[0019] Universal rollers 13 are provided at the four corners of the bottom of the tank body 1, and push rods 14 are provided on both sides of the tank body 1; in the specific use process, the double-discharge liquid suction filter is convenient to push and slide, has a wide range of applications, and reduces the difficulty of work for the staff.

[0020] When the utility model is used, the working process is as follows:

[0021] Connect the hose 15 of the tank body 1 with the air suction port 16 of the high-pressure fan 2 to make the tank body 1 communicate with the high-pressure fan 2, turn on the motor 3, and the high-pressure fan 2 works. The high-pressure fan extracts the air in the tank body 1 through the air suction port 16 and the hose 15 to generate negative pressure in the tank body 1. Connect one end of the water suction pipe (not shown in the figure) to the suction port 5, insert the other end of the water suction pipe into the liquid or aim at the impurities to be cleaned, open the manual valve of the suction port 5, and under the action of negative pressure suction, the liquid or impurities are sucked into the filter barrel 4. The filter screen barrel 9 in the filter barrel 4 intercepts large particles of impurities. When the suction is weak, the filter screen barrel 9 can be taken out of the filter barrel 4, clean the impurities in the filter screen barrel 9, and restore the filtering capacity of the filter barrel 4. When the liquid level in the tank body 1 reaches a high level, the liquid level detection switch 12 will send a signal to the motor 3, the motor 3 is turned off, and the high-pressure fan 2 stops working to prevent the liquid in the tank body 1 from exceeding the capacity. After the liquid level drops and resets, the equipment is turned on again to resume work.

[0022] The drainage process is as follows:

[0023] Gravity drainage method: When the motor 3 and the high-pressure fan 2 are stopped, the manual valve of the gravity drainage port 7 is opened to discharge the liquid in the tank body 2 from the gravity drainage port 7, which is suitable for discharging to a return liquid tank, a sewage pool or a water tank (not shown in the figure) below the gravity drainage port 7; after the tank body 1 is emptied, the manual valve 8 of the gravity drainage port 7 can be closed.

[0024] Pressure drainage method: close the manual valve of the suction port 5, connect the hose 15 of the tank body 1 with the gas inlet 17 of the high-pressure fan 2, so that the tank body 1 is connected to the high-pressure fan 2, open the manual valve of the pressure drainage port 6, connect the pressure drainage port 6 to the water tank (not shown in the figure) through the drainage pipe (not shown in the figure), turn on the motor 3, and the high-pressure fan 2 works. The high-pressure fan 2 inflates the tank body 1 through the gas inlet 17 and the hose 15, so that positive pressure is generated in the tank body 1, and the liquid is discharged through the drainage pipe to achieve pressure drainage, which is suitable for the working condition where the water tank is higher than the equipment. After the liquid is emptied, reset the manual valve and drainage pipe of the pressure drainage port 6 to restore the suction function.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
