[0029] Example 1

[0030] The purpose of this embodiment is to provide a cleaning device to solve the material accumulation problem in the prior art. Through the spraying system, the scattered materials and dust can be effectively blocked and screened, and the bearing 6 can be kept clean and lubricated, thereby improving the operating efficiency of the dry cleaning machine and the service life of the bearing 6.

[0031] like Figure 1 As shown, in one embodiment of the utility model, a cleaning device for a driving system of a rotary screen 3 of a dry cleaning machine is proposed, which is arranged in a cabin 2, wherein a rotary screen 3 and a driving wheel 5 are provided in the cabin 2, and the cleaning device comprises: a dust exhaust nozzle 4, a fixing rod and an air source; the fixing rod is mounted on the inner wall of the cabin 2, the dust exhaust nozzle 4 is mounted on the fixing rod, the dust exhaust nozzle 4 is located on the outer side of the rotary screen 3 in the radial direction, the dust exhaust nozzle 4 comprises an air inlet 42 and an air jet 41, the air inlet 42 is connected to the air source, the air jet 41 faces the joint surface between the rotary screen 3 and the driving wheel 5, the air jet 41 is a flat mouth, the extension line of the flat mouth is tangent to both the rotary screen 3 and the driving wheel 5, and forms an inclined wind curtain on the joint surface.

[0032] The air source may be a built-in air source or an external air source. Built-in air source: The dry cleaning machine is internally integrated with an air compressor, which can generate the required compressed air by itself. External air source: The dust exhaust nozzle 4 can be connected to an external compressed air supply system, such as a central air source of a factory or an independent air compressor.

[0033] The dust discharge nozzle 4 is designed to be flat, and its extension line is tangent to the rotary screen 3 and the driving wheel 5 to form an inclined air curtain. This design can effectively block and filter the materials and dust scattered during the dry cleaning process. The nozzle can be made of durable metal or plastic to adapt to the working environment inside the dry cleaning machine.

[0034] The cleaning device introduces compressed air to the joint surface between the rotary screen 3 and the driving wheel 5, and blows it in the form of an inclined wind curtain. Most of the scattered materials and dust during the operation of the dry cleaning machine are blocked and screened by the wind curtain, and the materials with larger particles are blown to the receiving bin 7 under the cabin 2. The dust is blown away to form a dispersed phase dust-containing gas with smaller mass, which is sucked into the dust removal unit by the top dust exhaust pipe 1. After the dry cleaning is completed, the interior of the cabin 2 can also be cleaned by the spray system by controlling the compressed air intake to ensure the cleanliness of the interior of the cabin 2.

[0035] It has been verified that during the dry cleaning process, scattered materials and dust on the bearing 6 of the drive wheel 5 can be automatically cleaned, no material accumulation occurs during the quarterly disassembly and maintenance, no dust accumulates on the surface of the bearing 6 of the drive wheel 5, and the cleanliness inside the cabin 2 is greatly improved, ensuring the long-term normal operation of the dry cleaning machine, improving the dry cleaning efficiency and the service life of the bearing 6.

[0036] The fixing rod includes a crossbar and a vertical rod, and the crossbar and the vertical rod form an L shape. The outer end of the crossbar is mounted on the inner wall of the cabin 2, and the vertical rod is located at the inner end of the crossbar. The dust exhaust nozzle 4 is mounted on the top of the crossbar. The L-shaped fixing rod provides a stable support so that the dust exhaust nozzle 4 can be stably mounted on the inner wall of the cabin 2. The dust exhaust nozzle 4 is mounted on the top of the crossbar to facilitate the correct alignment of the dust exhaust nozzle 4 with the joint surface of the rotary screen 3 and the driving wheel 5 to achieve the best cleaning effect.

[0037] The outer end of the cross bar is mounted on the inner wall of the cabin 2 by flanges and bolts, and the dust exhaust nozzle 4 is fixed to the top of the vertical bar by bolts and a pressure plate. The connection between the fixing rod and the cabin 2 by flanges and bolts is both firm and convenient for installation and maintenance.

[0038] like Figure 2 As shown, the dust exhaust nozzle 4 is duckbill-shaped, the air inlet 42 is tubular, the jet outlet 41 is rectangular, the air inlet 42 and the jet outlet 41 are in an arc transition, and the air inlet 42 is provided with an air joint 43. The design of the duckbill-shaped dust exhaust nozzle 4, combined with the tubular air inlet 42 and the rectangular jet outlet 41, and the arc transition between the two, makes the airflow more uniform and stable. The duckbill-shaped design can cover a larger area and provide a uniform and directional spraying effect.

[0039] A dust exhaust nozzle is provided on each of the two sides of the outer radial direction of the rotary screen 3, and the two dust exhaust nozzles are arranged symmetrically relative to the rotary screen 3. The symmetrical arrangement of the two dust exhaust nozzles relative to the rotary screen 3 can ensure that the materials and dust on both sides of the rotary screen 3 can be effectively cleaned, provide more comprehensive cleaning coverage, reduce dead angles, and improve the overall cleaning efficiency. At the same time, the internal structure of the cabin 2 is used to change the direction of part of the air volume and reflect it to the bearing 6 of the drive wheel 5 to achieve cleaning of the bearing 6 of the drive wheel 5.

[0040] The automatic blowing system is powered on after the dry cleaning machine is turned on. The parameters of the electronic control unit are set according to the density and cleanliness of the material to control the blowing time and blowing interval of the solenoid valve, thereby achieving the purpose of energy saving and consumption reduction while ensuring the cleanliness of the material and the intact performance of the bearing 6.

[0041] Example 2

[0042] Based on the cleaning device of Example 1, this embodiment proposes a dry cleaning machine, including a cabin 2, a rotary screen 3, a driving wheel 5, a cleaning device, a dust exhaust pipe 1, a material receiving bin 7, a material recovery tray 9 and a base 8, wherein the rotary screen 3, the driving wheel 5 and the cleaning device are all located in the cabin 2, the driving wheel 5 is symmetrically arranged on both sides of the rotary screen 3, the dust exhaust pipe 1 is arranged on the top of the cabin 2, the material receiving bin 7 is located at the bottom of the rotary screen 3, the material recovery tray 9 is located at the bottom of the material receiving bin 7, and the base 8 is installed on the ground.

[0043] The dust exhaust duct 1 is arranged on the top of the cabin 2, and is used to collect and discharge dust and fine materials generated during the dry cleaning process; the material receiving bin 7 is located at the bottom of the rotary screen 3, and is used to collect larger material particles; the material recovery tray 9 is located at the bottom of the material receiving bin 7, and is used to further collect and recover materials; the base 8 is installed on the ground to stabilize the support of the dry cleaning machine and ensure the smooth operation of the whole machine.
