[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0035] Embodiments of the present invention:

[0036] Embodiment 1

[0037] like Figure 1 As shown: a contactless cleaning device for a rubber conveyor belt, comprising a cleaning box 1; a gas generating mechanism 2 is installed inside the cleaning box 1, and through the setting of the gas generating mechanism 2, the extracted gas can be transported to the inside of a gas conveying pipeline 3, and one end of the gas conveying pipeline 3 is connected to a cleaning cylinder 5 through a gas conveying component; through the setting of the gas conveying component, the gas can be evenly transported to the inside of the cleaning cylinder 5; the cleaning cylinder 5 is usually installed at the lower part of the conveyor belt a, and it should be noted that: the outer surface of the cleaning cylinder 5 is provided with a gap 501 along the axial direction, so that the gas in the cleaning cylinder 5 can be discharged through the gap 501, forming a wind knife and cleaning the conveyor belt a; replacing the traditional scraper cleaning method, reducing the degree of wear of the conveyor belt a, and extending the service life of the conveyor belt a.

[0038] like Figure 2-4As shown: In detail: the gas generating mechanism 2 includes a shell 201 installed in the cleaning box 1; the upper part or the side part of the shell 201 can be respectively provided with an air inlet cover 202, through the setting of the air inlet cover 202, the external gas can flow into the shell 201, which can ensure the normal use of the high-speed fan 204 installed in the shell 201; and the speed of the high-speed fan 204 can be adjusted; and the size of the air intake can be adjusted; it should be noted that: a filter screen 203 is installed on one side of the air inlet cover 202, and the dust can be filtered for a second time through the filter screen 203 to prevent the dust from entering the interior of the shell 201 and causing damage to the high-speed fan 204; the air outlet of the high-speed fan 204 extends to the outside of the shell 201 The shell 201 is connected to the air inlet end of the gas delivery pipeline 3, so that gas can be delivered to the inside of the gas delivery pipeline 3; it should be noted that: a heat dissipation pipe 207 extending to the outside of the cleaning box 1 is installed on the shell 201. Through the setting of the heat dissipation pipe 207, the heat in the shell 201 can be directly discharged to the outside of the cleaning box 1; a pressure relief valve 205 is installed between the high-speed fan 204 and the gas delivery pipeline 3. If the cleaning cylinder 5 is blocked, the pressure relief valve 205 can be opened to relieve the pressure to avoid damage caused by excessive pressure in the gas delivery pipeline 3; and a connecting pipe 206 connected to the heat dissipation pipe 207 is installed at the exhaust end of the pressure relief valve 205, so that the gas after pressure relief can also be discharged through the heat dissipation pipe 207.

[0039] like Fig. 9 As shown in detail: the gas delivery assembly includes a conversion head 401 installed at the tail end of the gas delivery pipeline 3, and a plurality of connecting pipes 402 are installed on the conversion head 401. It should be noted that: each connecting pipe 402 is connected to the conversion head 401 at a connection point through a clamp (not shown in the figure); the outer surface of the cleaning cylinder 5 is equidistantly installed with a plurality of air inlets 403 along the axial direction. It should be noted that: the air outlet end of the connecting pipe 402 and the connection point of the air inlet 403 are also connected by a clamp (not shown in the figure). The advantages of this connection method are: good sealing, gas is not easy to leak, and at the same time, it is also convenient for disassembly; it should be noted that: the connecting pipe 402 is a hose, so that the cleaning cylinder 5 can be rotated and adjusted.

[0040] When cleaning the conveyor belt a on the conveying mechanism: the high-speed fan 204 can be turned on; the high-speed fan 204 can convey gas to the inside of the gas conveying pipeline 3, and the gas conveying pipeline 3 can convey gas to the inside of several connecting pipes 402 through the conversion head 401, and the multiple connecting pipes 402 can convey gas to different positions in the cleaning tube 5 through the air inlet 403 respectively, so that the gas can be evenly distributed in the cleaning tube 5, and the gas in the cleaning tube 5 can be discharged from the gap 501 to form a wind knife and clean the conveyor belt a.

[0041] Embodiment 2

[0042] The cleaning box 1 in the above-mentioned embodiment 1 can only be used outdoors; if it is raining or there is a lot of dust outdoors, rain or dust can easily enter the interior of the cleaning box 1, causing damage to electrical components (including high-speed fans); therefore, in order to solve the above-mentioned technical defects; the present application is improved on the basis of embodiment 1;

[0043] like Figure 2 As shown in Figure 5: shutters 22 are installed on both sides of the cleaning box 1, and the shutters 22 are set to prevent rainwater from the outside from entering the interior of the cleaning box; the electrical components and the gas generating mechanism 2 in the cleaning box 1 are protected; a ventilation hood 6 is installed on the outer side of the shutters 22, and several ventilation holes on the ventilation hood 6 are set downward; the setting of the ventilation hood 6 further plays a waterproof role;

[0044] like Figure 6 As shown: a dust bag 7 is also installed on the inner side of the shutter 22; and the dust bag 7 is located inside the cleaning box 1. In detail: the dust bag 7 includes a frame body 701 and a bag body 702, and the open end of the bag body 702 is sewn to the frame body 701. Through the setting of the bag body 702, the dust entering the cleaning box 1 can be filtered, thereby preventing dust from entering the interior of the cleaning box 1 and causing damage to electrical components (including high-speed fans).

[0045] It should be noted that: there are two ways to fix the frame body 701 and the ventilation hood 6, and this embodiment can adopt any of the following:

[0046] The first fixing method: a plurality of horizontal clamps (not shown in the figure) are installed inside the cleaning box 1, and the clamping ends of the horizontal clamps are used to clamp the frame body 701; if there is too much dust on the bag body 602, it is convenient to disassemble and carry out subsequent cleaning work.

[0047] The second fixing method: the ventilation hood 6 and the frame body 701 are connected by a plurality of fixing bolts (not shown in the figure). This fixing method has better firmness.

[0048] During the use of the high-speed fan 204, it is necessary to extract gas from the outside, and the outside gas first enters the interior of the cleaning box 1 through the ventilation hood 6. When the outside gas enters the interior of the cleaning box 1, the dust removal bag 7 can filter the dust in the air to prevent the dust from falling into the electrical components (including the high-speed fan) in the cleaning box 1 and causing damage; the filtered gas enters the interior of the cleaning box 1 and the shell 201 in turn for use by the high-speed fan 204.

[0049] Embodiment 3

[0050] There are usually multiple conveying mechanisms in a factory. If multiple conveying mechanisms are used at the same time, a cleaning mechanism needs to be installed next to each conveying mechanism, which leads to high production costs and high fees. Therefore, in order to overcome the technical defects mentioned above, the technology of the above embodiment can be improved;

[0051] like Figure 1 , or 9: Several flanges 8 are installed on the gas delivery pipeline 3, and each flange 8 can be connected to the branch pipeline 9; it should be noted that the flange 8 not connected to the branch pipeline 9 needs to be threadedly installed with a sealing cover 801 to play a sealing role to prevent the gas in the gas delivery pipeline 3 from leaking out during use; the tail end of each branch pipeline 9 is also connected to a cleaning cylinder 5 located below the conveyor belt a through a gas delivery component (which has been described in detail in Example 1 and will not be described in this embodiment), and the dust on the conveyor belt a can be cleaned separately through multiple cleaning cylinders 5; there is no need to install a cleaning mechanism next to each conveying mechanism, which reduces production costs,

[0052] like Fig. 9 As shown: It should be noted that: the head end of the multiple branch pipelines 9 and the tail end of the gas delivery pipeline 3 are respectively installed with control valves 10, and through the setting of multiple control valves 10, multiple cleaning cylinders 5 can be individually controlled;

[0053] If the conveyor belts a on multiple conveying mechanisms (the conveying mechanisms are already existing technologies and this application will not go into detail), the rotation speed of the high-speed fan 204 can be adjusted to increase the air intake volume. The high-speed fan 204 can convey gas to the interior of several branch pipelines 9 through the gas conveying pipeline 3. The tail ends of the multiple branch pipelines 9 and the tail ends of the gas conveying pipeline 3 can respectively convey gas to the interior of the gas conveying components. The multiple gas conveying components respectively convey gas to the interior of the cleaning tube 5. The gas in the multiple cleaning tubes 5 is discharged and the multiple conveyor belts a are cleaned. The production cost of the cleaning device is reduced, which is conducive to its popularization and use.

[0054] Embodiment 4

[0055] When the gas in the cleaning cylinder 5 cleans the conveyor belt a, the cleaned dust usually floats in the air, causing pollution to the surrounding environment; even the staff may absorb the dust into their bodies, causing harm to the staff; therefore, in order to overcome the above-mentioned technical defects, improvements are made on the basis of the above-mentioned embodiment:

[0056] like Figure 8 and 9As shown: an extension rod 11 is fixed to each end of each cleaning barrel 5, and a mounting base 12 is rotatably mounted on the two extension rods 11. Through the setting of the mounting base 12, the cleaning barrel 5 can be slightly rotated according to the use requirements to change the air outlet position of the cleaning barrel 5; it should be noted that: a fastening bolt 1201 is threadedly mounted on each mounting base 12, and the fastening bolt 1201 can pass through the mounting base 12 to fasten the cleaning barrel 5 to prevent the cleaning barrel 5 from rotating during use; every two mounting bases 12 are installed in the same dust collection box 13. Through the setting of the dust collection box 13, the dust after cleaning can be prevented from spreading into the air, the pollution to the air can be eliminated, and a good working environment can be provided for the staff; it should be noted that: the dust collection An opening (not shown in the figure) is provided on the side of the collecting box 13 close to the conveyor belt a, so that the material on the conveyor belt a can be conveyed normally; and a curtain (not shown in the figure) is installed at the opening to fit the conveyor belt a. The setting of the curtain can play a shielding role to prevent the cleaned dust from spreading to the outside of the dust collecting box 13 through the opening; a number of inspection and observation ports (not shown in the figure) are provided on the side of the dust collecting box 13. Through the setting of the inspection and observation ports, the situation in the dust collecting box 13 can be observed or the components in the dust collecting box 13 can be inspected; a closable box door 14 is rotatably installed on each inspection and observation port. Through the setting of the box door 14, the inspection and observation port can be closed to prevent dust from spreading to the outside of the dust collecting box 13 through the inspection and observation port.

[0057] like Fig. 9 As shown: a pulse bag dust collector 15 is installed on the top of the dust collection box 13 (the pulse bag dust collector is already a prior art and will not be described in detail in this application); and the opening at the bottom of the pulse bag dust collector 15 is connected to the top of the dust collection box 13, so that the dust floating in the dust collection box 13 can be extracted and put into the conveyor a for transportation; so that a slight negative pressure is formed inside the dust collection box to prevent dust from polluting the environment;

[0058] While cleaning the conveyor belt a, the pulse bag dust collector 15 can also be turned on to form a slight negative pressure inside the dust collection box 13; the dust blown away by the cleaning cylinder 5 can be adsorbed and collected by the pulse bag dust collector 15 in the dust collection box 13; after the pulse bag dust collector 15 collects a certain amount of dust, the dust adsorbed by the back-blowing system of the pulse bag dust collector 15 can be blown down to conveyor a, and then transported again to the next-level conveyor belt or container through the conveyor belt a.

[0059] Embodiment 5

[0060] The above-mentioned multiple embodiments use a plurality of connecting pipes 402 to transport gas to the interior of the cleaning tube 5; however, when transporting gas to the interior of the cleaning tube 5, it is easy to cause the gas pressure in the cleaning tube 5 to be unstable; for example: the air pressure at the position near the connecting pipe 402 in the cleaning tube 5 is relatively large; the air pressure at the position far from the connecting pipe 402 in the cleaning tube 5 is relatively small; the air pressure in the cleaning tube 5 is relatively uneven; if the gas in the cleaning tube 5 is discharged to the outside through the gap 501 and cleans the conveyor belt a; the wind force at different positions of the gap 501 is also different; resulting in different cleaning forces on the conveyor belt a, resulting in a relatively poor cleaning effect; therefore, in order to overcome the above-mentioned technical problems, improvements are made on the basis of the above-mentioned embodiments.

[0061] like Fig.10 As shown: a stirring cage 16 is coaxially arranged inside the cleaning barrel 5. During the high-speed rotation of the stirring cage 16, the gas entering the cleaning barrel 5 can be quickly dispersed and evenly distributed inside the cleaning barrel 5; a small motor 17 is installed at one end of one of the extension rods 11, and the output shaft of the small motor 17 extends to the interior of the cleaning barrel 5 and is installed with a fixed disk 18, and the fixed disk 18 is threadedly connected to the stirring cage 16 through a number of bolts. Through the cooperation of the small motor 17 and the fixed disk 18, the stirring cage 16 is driven, so that the stirring cage 16 can rotate at high speed inside the cleaning barrel 5; a fixed shaft 19 is fixed at the axis of the other end of the stirring cage 16, and a bearing 20 is fixed on the fixed shaft 19, and the bearing 20 is fixed on the bearing bracket 21, and the bearing bracket 21 is fixed on the inner side wall of the cleaning barrel 5. Through the arrangement of the fixed shaft 19, the bearing 20 and the bearing bracket 21, the stirring cage 16 is supported to prevent the stirring cage 16 from being deformed during use.

[0062] During the cleaning process of the conveyor belt a, the small motor 17 can be turned on. The small motor 17 can drive the stirring cage 16 to rotate at a high speed through the fixed plate 18. The stirring cage 16 can quickly break up the gas entering the cleaning cylinder 5 and evenly distribute it in the cleaning cylinder 5; when the cleaning cylinder 5 discharges outward through the gap 501, different positions of the gap 501 can discharge gas outward with the same force and clean the conveyor belt a with the same force, thereby improving the cleaning effect of the conveyor belt a.
