Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and particularly to a conveying device for ore dressing. Background Art

[0002] Ore dressing refers to the process of separating useful minerals from gangue minerals and separating various symbiotic (associated) useful minerals from each other as much as possible, removing or reducing harmful impurities by using the physical, chemical or physicochemical properties of different minerals in the ore, and adopting methods such as gravity separation, flotation, magnetic separation, and electrostatic separation to obtain materials required for smelting or other industries. The conveyor belt is mainly used to achieve continuous, efficient and stable transportation of materials in ore dressing.

[0003] The corrugated conveyor belt is one of the commonly used conveyor belts in ore dressing. By installing skirts on both sides of the conveyor belt, during the process of transporting ore dressing materials by the conveyor belt, the skirts of the corrugated conveyor belt can effectively prevent the ore dressing materials from slipping or scattering from both sides of the conveyor belt during transportation, reducing the need for transportation and reloading caused by the scattering of ore dressing materials. During the use of the existing corrugated conveyor belt, it needs to be cleaned regularly. Due to the special shape of the skirt, materials are easily accumulated at the skirt. Regular cleaning of the skirt can reduce the friction between the skirt and the conveyor belt, thereby prolonging the service life of the corrugated conveyor belt. However, due to the special shape of the skirt, there are many dead corners, so when manually cleaning the conveyor belt and its skirt by personnel, it is not only difficult to clean, consuming a lot of time, but also prone to incomplete cleaning, resulting in low cleaning efficiency of the corrugated conveyor belt.

[0016] 2. The present invention installs a circulation mechanism, and the circulation pump draws the cleaning liquid in the cleaning box into the circulation box.

This reciprocating motion can drive the cleaning liquid in the sewage area of ​​the circulation box to shake, which is beneficial to disperse the impurities and dirt on the outside of the filter plate in the liquid, thereby effectively preventing the filter plate from being blocked.

[0018] 4. The present invention installs a knocking assembly. When the second guide roller drives multiple levers to rotate through the first disc, the lever will contact the baffle rod and drive the counterweight rod to rotate through the baffle rod during the rotation. When the lever is separated from the baffle rod, the counterweight rod will hit the conveyor belt under the action of the coil spring and gravity, causing the conveyor belt and the material baffle skirt to vibrate. This is not only conducive to loosening dust and the like attached to the conveyor belt and the material baffle skirt, thereby further improving the cleaning effect of the side conveyor belt, but also conducive to assisting the side conveyor belt to shake off the cleaning liquid, so as to facilitate the rapid drying of the side conveyor belt.

[0030] Example 4: Please refer to Figure 1 , Figure 7 , in this embodiment, a knocking component is used to loosen the dust and impurities on the conveyor belt 1 and the material retaining skirt 7. The knocking component is installed on the cleaning mechanism. The knocking component includes two positioning shafts 33 symmetrically and fixedly installed on the outer side of the cleaning tank 8. A coil spring 34 is fixedly sleeved on the outer side of the positioning shaft 33. A connecting plate 35 is fixedly sleeved on the outer side of the coil spring 34. The coil spring 34 can drive the connecting plate 35 to rotate through the positioning shaft 33. A retaining pin 36 is fixedly connected to the end of the positioning shaft 33 away from the cleaning tank 8. The retaining pin 36 is used to prevent the connecting plate 35 from detaching from the positioning shaft 33. A counterweight rod 37 is movably attached to the inner side of the conveyor belt 1, and the connection between the counterweight rod 37 and the connecting plate 35 is a fixed connection. The counterweight rod 37 is used to knock the conveyor belt 1.

[0031] One end of the connecting plate 35 away from the counterweight rod 37 is fixedly installed with a stop rod 38. The stop rod 38 is located at the rear side of the lever 10. The connection mode between the lever 10 and the stop rod 38 is movable abutment. The lever 10 can drive the connecting plate 35 and the counterweight rod 37 to rotate through the stop rod 38. One end of the stop rod 38 away from the connecting plate 35 is movably embedded with a second ball 39. And the connection mode between the second ball 39 and the lever 10 is rolling contact. The second ball 39 can reduce the frictional resistance between the stop rod 38 and the lever 10.

[0032] Working principle: When cleaning the conveyor belt 1, the operator pours an equal amount of cleaning liquid into the cleaning tank 8 and the circulation tank 15, and then controls the first motor 4 and the second motor 5 to operate, so that the two first guide rollers 2 and the second guide roller 3 cooperate to drive the conveyor belt 1 to rotate. Since the parts of the conveyor belt 1 and the material retaining skirt 7 outside the second guide roller 3 are immersed in the cleaning liquid, and the second guide roller 3 drives a plurality of paddles 14 to rotate through the first disc 9, the lever 10, the second disc 11, etc. during rotation. The rotation of the plurality of paddles 14 can drive the cleaning liquid in the cleaning tank 8 to shake. During the rotation of the conveyor belt 1 and the material retaining skirt 7, the shaking cleaning liquid contacts the conveyor belt 1 and the material retaining skirt 7, and can quickly clean the conveyor belt 1 and the material retaining skirt 7, thereby effectively improving the cleaning efficiency of the edge conveyor belt.

[0033] During the process of cleaning the conveyor belt 1 and the material retaining skirt 7, the sewage pump 17 operates. The sewage pump 17 pumps the cleaning liquid containing impurities in the cleaning tank 8 into the circulation tank 15 through the first conduit 16 and the second conduit 18. Since the cleaning liquid in the cleaning tank 8 and the circulation tank 15 is equal in amount, when the cleaning liquid in the cleaning tank 8 is pumped into the circulation tank 15, the cleaning liquid filtered by the filter plate 21 in the circulation tank 15 will flow back into the cleaning tank 8 through the third conduit 19. By this method, the impurities and dirt in the cleaning tank 8 can be effectively reduced, which is beneficial to ensuring that the cleaning liquid in the cleaning tank 8 always has a good cleaning effect.

[0034] During the process of the cleaning liquid circulating in the cleaning tank 8 and the circulation tank 15, the second guide roller 3 drives a plurality of arc-shaped stoppers 30 to rotate through the third disc 29. During the rotation of the arc-shaped stoppers 30, the arc-shaped edges drive the ejector rod 31 and a plurality of water deflecting plates 24 to move to the right. When the first ball 32 at the end of the ejector rod 31 disengages from the arc-shaped stopper 30 through the straight edge, the plurality of water deflecting plates 24 will instantaneously move back under the driving force of the compression elastic force of the spring 27. Repeating this process can drive the cleaning liquid in the sewage area of the circulation tank 15 to shake, which is beneficial to dispersing the impurities, dirt, etc. outside the filter plate 21 in the liquid, thereby effectively preventing the filter plate 21 from being blocked.

[0035] During the process that the second guide roller 3 drives a plurality of lever rods 10 to rotate through the first disc 9, the lever rods 10 will abut against the stop rod 38, and during the continuous rotation of the lever rods 10, the lever rods 10 will drive the connecting plate 35 and the counterweight rod 37 to rotate through the stop rod 38. When the lever rods 10 rotate away from the stop rod 38 instantaneously, the counterweight rod 37 will impact the conveyor belt 1 under the action of the coil spring 34 and gravity, causing the conveyor belt 1 and the skirt edge 7 to vibrate. This is not only conducive to loosening dust and the like adhering to the conveyor belt 1 and the skirt edge 7, thereby being able to further improve the cleaning effect on the sidewall conveyor belt, but also conducive to assisting the sidewall conveyor belt to shake off the cleaning liquid, facilitating the rapid drying of the sidewall conveyor belt.
