[0023] Specifically, the drying and filtering device 2 includes a connection box 21, a mesh box 23, a silica gel desiccant 24, a first electric telescopic rod 25, a moving plate 26 and a filtering component 27. A connection box 21 is installed between the heating component 6 and the water tank component 3. A mesh box 23 is arranged inside the connection box 21. The inside of the mesh box 23 is filled with a silica gel desiccant 24. A moving plate 26 is installed below the mesh box 23. The moving plate 26 and the connection box 21 are connected through a first electric telescopic rod 25. A filtering component 27 is installed on one side of the connection box 21 and at a position outside the top of the suction pipeline 4.

[0024] By adopting the above technical solution, the device can process the moisture in the water-treated air through the cooperation of the mesh box 23 and the silica gel desiccant 24 when needed, thereby reducing the possibility that the operation of the coating machine 8 is adversely affected.

[0025] Specifically, the drying and filtering device 2 further includes a threaded block 22. The threaded block 22 is installed at the top of the connection box 21 and is located on the side of the heating component 6 away from the coating machine 8 through threading.

[0026] By adopting the above technical solution, when needed, the staff can drive the mesh box 23 and other structures to move below the threaded block 22 through the first electric telescopic rod 25, and then unscrew the threaded block 22 to replace the silica gel desiccant 24.

[0027] Specifically, the filtering component 27 includes a vibrator 271, a fixed box 272, and a filter net 273. A fixed box 272 is installed on one side of the connection box 21 and is located outside the top of the air suction pipe 4.

The vibrator 271 is started to drive the filter net 273 to vibrate, thereby preventing the filter net 273 from being blocked. Then the air passes through the air suction pipe 4 and enters the water tank component 3. The water tank component 3 stores water in advance, and most of the impurities in the air are filtered by water as a filtering medium. Then the air passes through the mesh box 23 in the connection box 21 and contacts the silica gel desiccant 24. The silica gel desiccant 24 dries the air. Then the air enters the heating component 6, and the heating component 6 is controlled to perform heating work. Then the air passes through the pipe component 7 and enters the coating machine 8, thereby performing the air intake work. The staff can drive the moving plate 26, the mesh box 23 and other structures to move below the threaded block 22 through the first electric telescopic rod 25 when needed, and then unscrew the threaded block 22 to replace the silica gel desiccant 24. The base 1 plays a supporting role.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is as follows: The air intake connection device 5 includes a second electric telescopic rod 51, a connecting frame 52, a hose 53, and a docking frame 54. A second electric telescopic rod 51 is installed on one side of the top of the water tank assembly 3 away from the coating machine 8. A docking frame 54 is arranged above the fixed box 272. The second electric telescopic rod 51 and the docking frame 54 are connected through a connecting frame 52. A hose 53 is installed above the docking frame 54.

[0032] By adopting the above technical solution, the device can adjust the air intake position to a certain extent through the cooperation of structures such as the hose 53 and the docking frame 54 when needed, so as to better meet the working needs in different situations.

[0033] Specifically, the height of the outer bottom surface of the docking frame 54 is equal to the height of the outer top surface of the fixed box 272.

[0034] By adopting the above technical solution, the device can ensure that the outer bottom surface of the docking frame 54 is closely attached to the outer top surface of the fixed box 272, thereby preventing air leakage and ensuring the normal progress of the air intake work.

[0035] When this embodiment is in use, when the air intake position needs to be adjusted, the staff starts the second electric telescopic rod 51 in the air intake connection device 5, and then drives the docking frame 54 to move through the connecting frame 52 until the docking frame 54 is docked with the fixed box 272. Then the staff places the end of the hose 53 at the required air intake position to carry out the adjustment work, which better meets the working needs in different situations.

[0036] In this utility model, the water tank assembly 3 composed of a water tank, a valve and a sensor, the suction pipeline 4, the heating assembly 6 composed of a heating pipeline and a resistance wire, the pipeline assembly 7 composed of an electromagnetic switch valve, a speed regulating valve, an air inlet pipeline and a filter, and the structure and principle of the coating machine 8 have been disclosed in a vacuum coating machine air inlet device with a Chinese patent application number of 201621306532.9. Its working principle is as follows: an air inlet pipeline is arranged at the air inlet of the coating machine, a water tank with a suction port and an air outlet is provided, and a heating pipeline with two ends respectively communicating with the air outlet of the water tank and the air inlet pipeline and heated by a resistance wire; the suction port of the water tank is provided with a suction pipeline with the lower end extending to the bottom of the water tank. Most of the impurities in the air can be filtered by water as a filtering medium, so that the impurities adhere to the water and precipitate at the bottom of the water tank, and the heating pipeline can remove the moisture in the air to avoid the moisture entering the equipment and damaging the equipment; a filter, an electromagnetic switch valve and a speed regulating valve are respectively arranged on the air inlet pipeline; the air inlet end of the filter is communicated with the air outlet end of the speed regulating valve, and the air inlet end of the speed regulating valve is communicated with the air outlet end of the electromagnetic switch valve. Among them, the speed regulating valve can effectively control the air flow rate, and finally the final filtration is realized through the filter. Since most of the impurities in the air have been filtered, the service life of the filter can be increased; a filter screen is also arranged at the air inlet end of the suction pipeline, which can pre-filter larger particles, and has a low cost and is convenient to replace; the bottom of the water tank is inclined, and a drain port controlled by a valve is arranged at the lowest part of the bottom of the water tank, which is convenient for discharging the impurities precipitated at the bottom; a sensor for detecting the water level is also arranged in the water tank to avoid the water entering the heating pipeline due to too large air flow rate; the resistance wire, the electromagnetic switch valve, the speed regulating valve and the sensor are respectively connected to the controller on the original coating machine by wires to realize automatic control.

[0037] In this utility model, the structure and principle of the vibrator 271 have been disclosed in an easy-to-clean concrete mixing device with a Chinese patent application number of 201821054815.8. Its working principle is composed of elements such as springs, mass blocks, motors, etc. When the springs or mass blocks are subjected to external forces from the motors, elastic deformations or displacements will occur, thereby generating vibrations.

[0038] Working principle and usage process of the present utility model: When the coating machine 8 needs to use the device for air intake work, air enters the fixed box 272 in the filter component 27 of the drying and filtering device 2, and the filter net 273 conducts primary filtration. The vibrator 271 is started to drive the filter net 273 to vibrate, thereby preventing the filter net 273 from being blocked. Then the air passes through the suction pipe 4 and enters the water tank component 3. There is water pre-stored in the water tank component 3, and most of the impurities in the air are filtered by water as the filtering medium. Then the air passes through the mesh box 23 in the connection box 21 and contacts the silica gel desiccant 24. The silica gel desiccant 24 conducts drying treatment on the air. Then the air enters the heating component 6, and the heating component 6 is manipulated to perform heating work. Then the air passes through the pipe component 7 and enters the coating machine 8, thereby performing air intake work. The staff can drive structures such as the moving plate 26 and the mesh box 23 to move below the threaded block 22 by the first electric telescopic rod 25 when needed, and then unscrew the threaded block 22 to replace the silica gel desiccant 24. The base 1 plays a supporting role; when the air intake position needs to be adjusted, the staff starts the second electric telescopic rod 51 in the air intake connection device 5, thereby driving the docking frame 54 to move through the connecting frame 52 until the docking frame 54 is docked with the fixed box 272. Then the staff places the end of the hose 53 at the required air intake position, thereby performing the adjustment work, better meeting the working needs in different situations.
