[0002] Traditional mechanical scraper cleaners remove materials by directly contacting the scraper with the belt surface, which results in severe belt wear, poor cleaning effect on sticky materials, and easy generation of secondary dust. Although air knife cleaning technology exists, it still suffers from drawbacks such as uneven airflow, high energy consumption, and poor effectiveness on wet and sticky materials. Summary of the Invention

[0008] In a preferred embodiment of the air-film conveyor belt cleaning device of the present invention, the air holes in the air hole array are arranged alternately in two adjacent rows.

[0009] In a preferred embodiment of the air-film conveyor belt cleaning device of the present invention, the diameter of the air hole is 0.5~2mm.

[0010] As a preferred embodiment of the air-film conveyor belt cleaning device of the present invention, it further includes a support base, and the cleaner body is disposed on the support base.

The lifting adjustment assembly includes two columns fixedly installed on the base. The columns are hollow columnar structures with a transmission rack movably sleeved inside. The transmission rack meshes with a drive gear rotatably disposed inside the column. An adjustment knob for driving the drive gear to rotate synchronously is provided on the side of the column. The upper end of the transmission rack is connected to the cleaner body.

[0012] In a preferred embodiment of the air-film conveyor belt cleaning device of the present invention, the two columns are arranged sequentially along the conveying direction of the conveyor belt, and the upper end of each transmission rack is hinged to the lower end of the cleaner body through a hinge seat.

[0013] The beneficial effects of this invention are: (1) The present invention uses an air film cleaning device to clean the conveyor belt, forming a uniform and stable air film between the working surface of the cleaner body and the conveyor belt, avoiding direct friction between the cleaner and the conveyor belt, effectively reducing wear and extending the service life of the conveyor belt and the cleaning device.

[0016] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the following description of the embodiments will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a schematic diagram of the structure of the air-film conveyor belt cleaning device provided by the present invention; Figure 2 This is a schematic diagram of the air hole array in the air-film conveyor belt cleaning device provided by the present invention; The components include: 1. Sweeper body; 2. Compressed air pipeline; 3. Air chamber; 4. Air hole; 5. Base; 6. Transmission rack; 7. Adjustment knob. Detailed Implementation

[0018] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] Figure 1 This is a schematic diagram of the structure of the air-film conveyor belt cleaning device provided in this application embodiment. The device includes a cleaner body 1 and a compressed air pipeline 2. The compressed air pipeline 2 delivers compressed air to the air chamber 3 of the cleaner body 1, and the compressed air is ejected from the air hole 4 communicating with the air chamber 3, thereby forming a uniform and stable air film between the working surface of the cleaner and the surface of the belt, which is used to block and peel off the attached material.

[0020] Specifically, the cleaner body 1 has an air chamber 3 inside. Simultaneously, the upper surface of the cleaner body 1 is designated as a working surface, and an air hole 4 communicating with the air chamber 3 is formed on this working surface. (See also...) Figure 2 The system has several pores 4, which are evenly arranged in an array. In this array of pores 4, the distance between any two adjacent pores 4 in any row is equal, and the row spacing between any two rows of pores 4 is equal.

[0021] It should be noted that the angle between the air jet direction of the air hole 4 and the running direction of the conveyor belt is 20°~45°.

[0022] In this embodiment, the diameter of each pore 4 is 0.5~2mm, and the spacing between two adjacent pores 4 in any row is 3~8 times the pore diameter.

[0023] Preferably, in the array of air holes 4, adjacent rows of air holes 4 are arranged alternately. By setting adjacent rows of air holes 4 to be staggered, the gas ejected from the air holes 4 on the working surface is more evenly distributed, thereby forming a uniform and stable air film between the working surface of the cleaner body 1 and the surface of the conveyor belt.

[0024] In addition, the aforementioned air-film conveyor belt cleaning device also includes a support base, which supports and lifts the cleaner body 1 and adjusts the gap between the cleaner body 1 and the conveyor belt. Specifically, the support base includes a base 5 and a lifting adjustment assembly mounted on the base 5. The lifting adjustment assembly includes two columns fixedly mounted on the base 5. The columns are hollow columnar structures, with a transmission rack 6 movably fitted inside, and the transmission rack 6 meshes with a drive gear rotatably mounted inside the column. An adjustment knob 7 is provided on the side of the column to drive the drive gear to rotate synchronously. By rotating the adjustment knob 7, the transmission rack 6 can be moved up and down, thereby adjusting the gap between the cleaner body 1 and the conveyor belt.

[0025] In addition, the upper ends of both transmission racks 6 are hinged to the lower ends of the sweeper body 1 via hinge seats. According to actual usage requirements, the tilt angle of the sweeper body 1, that is, the angle between the sweeper body 1 and the conveyor belt, can be adjusted by individually controlling the height of the two transmission racks 6.

[0026] In this embodiment, the sweeper body 1 is made of polyurethane material with a Shore hardness of A70~A90.

[0027] The above technical solution will be further explained below through specific embodiments.

[0028] Conveyor belt width: 1200mm.

[0029] Micropore configuration: 3 rows of 150 pores (60° staggered angle).

[0030] Pressure range: 0.5±0.1 MPa.

[0031] Gas consumption: 6 m³ / min.

[0032] Results: Surface residue ≤20g / m² (reduced by 89%).

[0033] Compared with traditional mechanical scraper cleaners, the residue on the conveyor belt surface is reduced by 85%, the lifespan of the polyurethane cleaner is increased by 2.5 times, and energy consumption is reduced by 20% compared with continuous air knife.

[0034] Therefore, the technical solution of this application uses an air film cleaning device to clean the conveyor belt, forming a uniform and stable air film between the working surface of the cleaner body 1 and the conveyor belt, thereby achieving non-contact cleaning and effectively solving the problems of low cleaning efficiency, rapid belt wear and secondary pollution in the prior art.

[0035] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
