Claims

1. A screen cleaning device, comprising: an inner shell having an inner door and at least one drain pipe respectively at its front end and bottom; a conveying module and a plurality of limiting members respectively at the bottom and top sides of the inner shell; the conveying module being used to hold a screen; a container having an inlet and a first outlet; the inlet being connected to the drain pipe; the container containing a predetermined volume of cleaning agent; the first outlet being connected to a first pump; and a plurality of spray pipes having a plurality of nozzles spaced apart on one side and an inlet pipe at the center of the other side; each inlet pipe being connected to a spray valve; each spray pipe being located on opposite sides inside the inner shell; each spray valve being located on opposite sides outside the inner shell; each spray valve being connected to the first pump; each spray valve being connected to a power unit, the power unit driving each spray pipe to rotate by a predetermined angle, while the first pump and each spray valve actuating, causing the cleaning agent to be output from each nozzle and used to rinse the screen.

2. The screen cleaning device as described in claim 1, wherein the container is provided with a plurality of partitions to form a front tank, a first middle tank, a second middle tank, and a rear tank; the inlet and the first outlet are respectively located at the top of the front tank and the bottom of the first middle tank; a second outlet is provided at the bottom of the rear tank; the first outlet is connected to the first pump; a first filter, a first check valve, a first control valve, a second filter, a first three-way pipe, and a second three-way pipe are sequentially and alternately arranged between the first pump and the inlet pipe; the first three-way pipe includes a first branch pipe, a second branch pipe, and a third branch pipe; the second three-way pipe includes a... The system includes a fourth branch pipe, a fifth branch pipe, and a sixth branch pipe. The first branch pipe is connected to the second filter, the second branch pipe is connected to a second check valve, the third branch pipe is connected to the fourth branch pipe, and the fifth and sixth branch pipes are respectively connected to each of the spray valves. The first control valve includes a first flow channel, a second flow channel, and a third flow channel. The first check valve is connected to the first flow channel, and the second flow channel is connected to the second filter. Thus, when the first pump is started, the cleaning agent passes sequentially through the first filter, the first check valve, the first flow channel, the second flow channel, the second filter, the first three-way pipe, the second three-way pipe, and each of the spray valves, and is sprayed out from each nozzle of each spray pipe.

3. The screen cleaning device as described in claim 2, wherein the second check valve is connected to a second control valve, and the second control valve is connected to an air compressor, so that when the air compressor is started, the first pump and the first control valve are closed, allowing air from the air compressor to pass through the second check valve, the first three-way pipe and the second three-way pipe, and be ejected from the nozzles of each of the spray pipes.

4. The screen cleaning device as described in claim 2, wherein the second outlet is connected to a second pump, the second pump is sequentially connected to a third filter and a third check valve, the third check valve is connected to the third flow channel of the first control valve, thereby, when the second pump is started, the first pump is turned off, and the cleaning agent sequentially passes through the third filter, the third check valve, the third flow channel, the second flow channel, the second filter, the first three-way pipe, the second three-way pipe and each of the spray valves, and is sprayed out from each nozzle of each spray pipe.

5. The screen cleaning device as described in claim 2, wherein the cleaning agent is sequentially overflowed from the front container into the first middle container, the second middle container and the rear container; the bottom of the front container, the first middle container, the second middle container and the rear container are respectively provided with a drain hole, and the height of each drain hole is lower than the first outlet and the second outlet.

6. The screen cleaning device as claimed in claim 1, wherein the screen is pushed in by the inner door, the bottom and top of the screen are respectively placed on the conveying module and abutted by each of the limiting members, the screen is pushed by a force to move on the conveying module to the end of the conveying module and close the inner door; the conveying module is pivotally provided with a plurality of rollers.

7. The screen cleaning device as claimed in claim 1, wherein the power unit of the water spray valve includes a driven member, an active member and a power source, the driven member being connected to the water inlet pipe and the active member respectively, and the active member being connected to the power source.

8. The screen cleaning device as claimed in claim 1, wherein the inner shell is disposed within an outer shell, the inner shell and the outer shell are separated by a predetermined distance, the front end face of the outer shell is provided with an outer door corresponding to the inner door, and the inner door and the outer door are further provided with at least one detection door or detection window.

9. The screen cleaning apparatus as described in claim 8, wherein an exhaust filter is provided at the top of the outer casing, and the exhaust filter is in communication with the inner casing.
