Specific embodiments

[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0021] As Figure 1-2 shown, the utility model provides a technical solution: a conveying belt cleaning device, including a conveying cover 1, with a discharge port opened downward on one side of the conveying cover 1. A vibration motor 12 is installed on the side wall of the discharge port. By turning on the vibration motor 12, the materials on the inner wall of the discharge port can be shaken off to prevent adhesion. A rotatable conveying roller 2 is arranged in the conveying cover 1, and a conveying belt 3 is drivingly connected to the conveying roller 2.

[0022] A rotatable roller brush 4 is provided below the conveyor belt 3. The roller brush 4 is located above the discharge port. A cleaning fan 5 and a purging air box 6 are respectively provided at the bottom of the conveying cover 1. The air outlet of the purging air box 6 is flat, and this flat air outlet faces the conveyor belt 3. The air outlet direction of the purging air box 6 is opposite to the running direction of the conveyor belt 3.

[0023] It further includes a spray washing assembly 7. The spray washing assembly 7 includes a spray washing cover 71. A rotatable cleaning roller 72 is installed at the top of the spray washing cover 71. The cleaning roller 72 is in contact with the conveyor belt 3. A pump 73, a spray head 74 and an activated carbon filter layer 75 are respectively provided in the inner cavity of the spray washing cover 71. The water spraying port of the spray head 74 faces the cleaning roller 72. A water inlet 76 and a drain port 77 are also provided on the spray washing cover 71. After the wastewater after spray washing is filtered by the activated carbon filter layer 75, it can be pumped and reused by the pump 73.

[0024] A drying cover 8 is embedded at the bottom of the conveying cover 1. The length of the drying cover 8 is 5 - 8 meters to ensure that the moisture on the conveyor belt 3 is completely dried. The drying cover 8 is supplied with air by an external fan 9, and a heating wire 10 is provided inside the drying cover 8.

[0025] A water absorbent cloth 11 is provided at the bottom of the inner wall of the conveying cover 1. The water absorbent cloth 11 is in contact with the bottom of the conveyor belt 3. As a precaution, by providing the water absorbent cloth 11, a small amount of moisture on the conveyor belt 3 can be wiped clean.

[0026] A negative pressure dust collection cover 13 and a dust collector 14 are installed at the top of the conveying cover 1. When the dust collector 14 is turned on, the dust in the conveying cover 1 can be absorbed through the negative pressure dust collection cover 13.

[0027] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] During use, the conveying roller 2 drives the cement material on the conveyor belt 3 to move, and the cement is discharged through the discharge port on the right. The roller brush 4 is driven to rotate by an external motor, and the residual powder on the conveyor belt 3 is cleaned. At the same time, the cleaning fan 5 is started, and a flat strong air flow is blown out through the flat air outlet of the purging air box 6 to purge the powder on the conveyor belt 3. The combined use of the roller brush 4 and the purging air box 6 can remove a large amount of powder and discharge it through the discharge port.

[0029] Then the pump 73 is turned on, and clean water is sprayed on the conveyor belt 3 through the spray head 74, and the residual powder on the conveyor belt 3 is cleaned by multiple groups of cleaning rollers 72, so as to completely clean the powder on the conveyor belt 3.

[0030] Afterwards, turn on the fan 9 and the heating wire 10, and the fan 9 supplies air into the drying hood 8. The air is heated by the heating wire 10 and contacts the conveyor belt 3, thereby drying the residual moisture on the conveyor belt 3. At this point, all the work is completed and the conveyor belt 3 can continue to be put into use.

[0031] To summarize, the conveyor belt cleaning device, by setting up a cleaning device that integrates spray cleaning, spray washing and drying, first sprays the belt to clean it, sweeping a large amount of dust off the belt, and then cleans the belt a second time through the spray washing system to ensure that the dust is completely cleaned. In order to allow the belt to be put into normal circulation, the belt is dried by a drying device, thereby achieving the purpose of efficiently cleaning the belt dust.
