Description

Technical Field

[0001] The utility model relates to the technical field of metal piece surface treatment, in particular to a spraying device for cleaning oil stains on the surface of a metal plate. Background Art

[0002] At present, some antique buildings are built with aluminum instead of wood. On the one hand, it reduces the amount of wood and reduces costs. On the other hand, aluminum has strong corrosion resistance and increases service life, making antique buildings durable and beautiful for a long time. However, there is a layer of oil on the surface of aluminum plates when they are processed in raw material factories. Therefore, these oil stains need to be cleaned before subsequent processing in antique building manufacturing plants. The usual practice is to spray cleaning liquid on the surface of aluminum plates. At present, there is no special cleaning liquid spraying device. It relies on manual holding of cleaning buckets and connecting booster pumps for spraying operations. The amount of cleaning liquid carried each time is limited, and the operation efficiency is low. Summary of the invention

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a spraying device for cleaning oil stains on the surface of a metal plate.

[0004] The specific scheme of the utility model is: a spray device for cleaning oil stains on the surface of a metal plate, comprising a trolley, a spray tank is mounted on the trolley, an air pump is arranged on one side of the spray tank, a cleaning liquid for cleaning oil stains on the metal surface is filled in the spray tank, a liquid outlet pipe, an air inlet pipe and a liquid replenishing pipe are arranged on the top of the spray tank, the inner end of the air inlet pipe is located above the liquid level of the cleaning liquid, the outer end of the air inlet pipe is connected to the air pump through a pipeline, the bottom end of the liquid outlet pipe extends toward the bottom end of the spray tank, a hose is arranged on the top end of the liquid outlet pipe, a nozzle is arranged at one end of the hose, and a control valve is arranged on the hose or the nozzle.

[0005] Furthermore, a pressure gauge is installed on the top of the spray tank, and the pressure gauge is used to display the air pressure in the tank.

[0006] Furthermore, a liquid level gauge is installed on the top of the spray tank, and the liquid level gauge is used to measure the liquid level of the cleaning liquid in the tank.

[0007] Furthermore, a locking cover is provided at the top of the infusion tube.

[0008] Furthermore, a one-way valve is installed on the air inlet pipe, and the one-way valve only allows gas to flow into the spray tank.

[0009] Furthermore, an air release valve is provided on the top of the spray tank, and the air release valve is used to release the pressure of the gas in the spray tank.

[0010] Compared with the prior art, the utility model has the following beneficial effects: a trolley is used to carry a spray tank carrying a large amount of cleaning liquid for continuous spraying, thereby improving the cleaning work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See also Figure 1-5 The present embodiment is a spraying device for cleaning oil stains on the surface of a metal plate, comprising a trolley 1, a spray tank 3 is mounted on the trolley 1, an air pump 2 is arranged on one side of the spray tank 3, a cleaning liquid for cleaning oil stains on the metal surface is contained in the spray tank 3, a liquid outlet pipe 11, an air inlet pipe 5, and a liquid replenishing pipe 10 are arranged on the top of the spray tank 3, the inner end of the air inlet pipe 5 is located above the liquid level of the cleaning liquid, the outer end of the air inlet pipe 5 is connected to the air pump 2 through a pipeline, the bottom end of the liquid outlet pipe 11 extends toward the bottom end of the spray tank 3, a hose 8 is arranged on the top end of the liquid outlet pipe 11, a nozzle 9 is arranged on one end of the hose 8, and a control valve is arranged on the hose 8 or the nozzle 9.

[0018] Furthermore, a pressure gauge 6 is installed on the top of the spray tank 3, and the pressure gauge 6 is used to display the air pressure in the tank.

[0019] Furthermore, a liquid level meter 7 is installed on the top of the spray tank 3, and the liquid level meter 7 is used to measure the liquid level of the cleaning liquid in the tank.

[0020] Furthermore, a locking cover 4 is provided at the top of the liquid infusion tube 10, and the locking cover 4 can cover the liquid infusion tube 10 tightly when the air pressure in the spray tank 3 is within a certain range, so as to prevent the cover from loosening and releasing pressure.

[0021] Furthermore, a one-way valve is installed on the air inlet pipe 5 , and the one-way valve only allows gas to flow into the spray tank 3 .

[0022] Furthermore, a deflation valve is provided on the top of the spray tank 3 , and the deflation valve is used to release the pressure of the gas in the spray tank 3 .

[0023] The working principle of the utility model is as follows: move the trolley 1 to the target area, then turn on the air pump 2 to increase the air pressure in the spray tank 3. The gradually increased air pressure will squeeze the cleaning liquid in the spray tank 3 toward the liquid outlet pipe 11, and finally spray it out from the nozzle 9. The flow rate of the sprayed cleaning liquid is controlled by the control valve, and the spray position and angle can be adjusted arbitrarily by holding the nozzle 9.

[0024] After the cleaning operation is completed, observe the liquid level gauge 7. If it is determined that the cleaning liquid needs to be supplemented, open the air valve and observe the pressure gauge 6. When the pressure gauge 6 shows that the air pressure in the tank has dropped to atmospheric pressure, open the anti-loosening cover 4 and supplement the cleaning liquid into the spray tank 3 through the liquid supplement pipe 10. After the supplement is completed, cover the anti-loosening cover 4.
