Description

Technical Field

[0001] The invention relates to a conveying device, in particular to a three-dimensional cleaning device for sticky materials on a belt working surface. Background Art

[0002] Belt conveyor is the most important equipment for conveying and loading and unloading bulk materials. It can be widely used in mining, metallurgy, building materials, chemical industry, electricity, food processing and other industrial fields. Belt conveyor can be seen in coal mines, metal mines, steel enterprises, ports, cement plants and other places. During the conveying process, the surface of the belt in the conveyor belt device will stick to a lot of residual materials. The traditional way to clean the residual materials on the return journey of the belt working surface is to use a fixed scraper blade for cleaning. Since the scraper acts on the residual materials in a single direction, there is always a gap between the scraper and the belt. In addition, the material is sticky, and the residual materials adhere more tightly under the joint action of the scraper and the belt. After repeated cycles, it becomes thicker and thicker, and finally the cleaner fails, causing the entire belt corridor to scatter materials and dust, and the surface roller and tensioning roller to stick to the material, causing surface wear and the belt to run all over. The usual method is to adjust the cleaner spring tighter, which is easy to scratch the belt, and the scraper and belt are also worn out. Summary of the invention

[0003] The purpose of the present invention is to provide a three-dimensional cleaning device for sticky materials on a belt working surface with good cleaning effect.

[0004] To achieve the above purpose, the technical solution of the present invention is:

[0005] The present invention discloses a three-dimensional cleaning device for materials sticking to the working surface of a belt, comprising a frame, two unpowered rollers, a cleaning belt, a vibrating device and a material return plate; the two unpowered rollers are mounted on the frame, the cleaning belt is wound around the two unpowered rollers, the cleaning belt is located below the belt in a belt conveyor and is attached to the working surface of the belt of the belt conveyor, the vibrating device is mounted on the frame, the vibrating device is in contact with the non-working surface of the belt and is located above the cleaning belt, and the material return plate is obliquely mounted on the frame and is located below the cleaning belt.

[0006] The surface of the cleaning belt is provided with a plurality of pits.

[0007] The cleaning belt is an adhesive belt with honeycomb holes on the surface.

[0008] The vibration device includes a vibration bag, a vibration motor, a vibration shaft, and blades; the vibration motor is installed on a frame, the vibration shaft is connected to the output shaft of the vibration motor, the blades are installed in the middle of the vibration shaft, the vibration shaft passes through the middle of the vibration bag, and both ends of the vibration shaft are rotatably connected to the fixing seats on both sides of the vibration bag through bearings, the fixing seats are installed on the frame, liquid is placed in the vibration bag, and the vibration bag is in contact with the non-working surface of the belt.

[0009] The vibration bag is made of soft material.

[0010] The invention also comprises a large block removing cleaner; the large block removing cleaner is installed on the frame and is located at the front end of the cleaning belt.

[0011] The invention also comprises a fine dust removal scraper blade group; the fine dust removal scraper blade group is installed on the frame, and the fine dust removal scraper blade group is located at the rear end of the cleaning belt.

[0012] The invention also comprises a return hopper which is arranged at the discharge port of the return plate.

[0013] The return material plate is made of polymer material.

[0014] After adopting the above scheme, since the present invention includes a frame, two non-powered rollers, a cleaning belt, a vibrating device, and a return plate, the residual material on the same part of the belt working surface on the belt conveyor is scraped at multiple angles and multiple times when passing through the honeycomb surface cleaning belt. The vibration motor in the vibrating device drives the blades to rotate through the vibration shaft. The blades stir the liquid in the vibration bag, causing the vibration bag to vibrate. The vibration bag made of soft material repeatedly vibrates up and down on the same part of the belt working surface on the belt conveyor, so that the residual material will be separated from the belt working surface, achieving a three-dimensional omnidirectional cleaning effect. At the same time, the surface of the cleaning belt adopts bionic technology to prevent sticking to the material, and the scraped material can be completely introduced into the return plate, and the return plate can introduce the scraped material into the return hopper. The invented device will not damage the belt and is suitable for any type of belt joint.

[0018] Figure 3 It is a forward schematic diagram of the vibration device of the present invention. DETAILED DESCRIPTION

[0019] like Figure 1 , Figure 2 As shown, the present invention is a three-dimensional cleaning device for sticky materials on the working surface of a belt, comprising two unpowered rollers 1, a cleaning belt 2, a vibrating device 3, a return plate 4, a large block remover 5, a fine dust removal scraper group 6, a return hopper 7, and a frame (not shown in the figure).

[0020] The two non-powered rollers 1 are installed on the frame of the belt conveyor, and the cleaning belt 2 is wound around the two non-powered rollers 1. The cleaning belt 2 is located below the belt 10 in the belt conveyor and the cleaning belt 2 is attached to the working surface of the belt 10 of the belt conveyor. The vibration device 3 is installed on the frame, and the vibration device 3 is in contact with the non-working surface of the belt 10. The return plate 4 is obliquely installed on the frame and is located below the cleaning belt 2. The large-block cleaner 5 and the fine dust removal scraper group 6 are both installed on the frame. The large-block cleaner 5 and the fine dust removal scraper group 6 are respectively located at the front end and the rear end of the cleaning belt 2. The return hopper 7 is arranged at the discharge port of the return plate 4 and connected with the return plate 4. The return plate 4 is made of polymer material, which is wear-resistant, smooth, and non-sticky.

[0021] The surface of the cleaning belt 2 has a plurality of pits. In the present embodiment, the cleaning belt 2 is an adhesive tape having honeycomb holes on its surface.

[0022] like Figure 2 , Figure 3 As shown, the vibration device 3 includes a vibration bag 31, a vibration motor 32, a vibration shaft 33, and a blade 34; the vibration motor 32 is mounted on a frame, the vibration shaft 33 is connected to the output shaft of the vibration motor 32, and the blade 34 is mounted in the middle of the vibration shaft 33, the vibration shaft 33 passes through the middle of the vibration bag 31, and the two ends of the vibration shaft 33 are rotatably connected to the fixing seats 311 on both sides of the vibration bag 31 through bearings, and the fixing seats 311 are mounted on the frame. Liquid (water in this embodiment) is placed in the vibration bag 31, and the vibration bag 31 contacts the non-working surface of the belt 10. The vibration bag 31 is made of soft material and filled with water to form a water-filled capsule.

[0023] like Figure 1 , Figure 2 As shown, the working principle of the present invention is:

[0024] 1. The bulk cleaner 5 installed at the front end of the cleaning belt 2 can preliminarily clean up the residual materials whose diameter is larger than the honeycomb aperture of the cleaning belt. The scraper is a ceramic scraper with a polyurethane patch, which is in slight contact with the belt 10 surface but not pressed tightly.

[0025] 2. The cleaning belt 2 with a honeycomb surface is an endless rubber belt, which is in tight contact with the working surface of the belt 10, and there is a linear speed difference between the two belt surfaces. In this way, the scraping pattern can allow the material to obtain forces in all directions on the plane within one passing cycle. The residual material enters the multiple pits (honeycomb holes) on the surface of the cleaning belt 2 and is then unloaded onto the return plate 4.

[0026] 3. A vibrating device 3 is installed on the non-working surface of the belt 10 above the cleaning belt 2. The vibrating device 3 causes the belt 10 to oscillate irregularly up and down through its own weight and the beating effect of water, and compresses the pits (honeycomb holes) of the cleaning belt 2 up and down to form a negative pressure attraction, so that the residual material is further separated under the beating and attraction up and down.

[0027] 4. When the cleaning belt 2 is no longer compressed and rebounds during the return journey, the remaining material falls from the pit (honeycomb hole) into the return plate 4 and returns to the return hopper 7 under the automatic action of the fine dust removal scraper group 6.

[0028] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope covered by the patent of the present invention.
