Description

Technical Field

[0001] The invention relates to a belt conveyor, in particular to a belt conveyor tail sealing box. Background Art

[0002] The tail sealing device of the traditional belt conveyor guide trough works by pressing down the sealing medium (rubber, sponge, etc.) to make it close to the belt surface to seal. The sealing medium and the moving belt surface slide and rub against each other for a long time. Under the action of pressure, the sealing medium will wear out after a period of time, and dust will leak out from the worn part. In addition, the materials adhering to the working surface of the belt during the return journey will be blocked outside by the tail sealing box and accumulate, which is environmentally friendly and may cause spontaneous combustion and cause safety risks. At the same time, the scattered materials cleaned by the cleaning staff on the ground cannot be directly placed on the tail belt of the belt conveyor and directly sent back to the conveying system. They need to be transported back to the material yard by a separate loading truck. Summary of the invention

[0003] The purpose of the present invention is to provide a belt conveyor tail sealing box with good sealing effect.

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

[0005] The present invention is a belt conveyor tail sealing box, comprising a fixing frame, a sealing roller, and an end side sealing plate; the two ends of the sealing roller are mounted on the frame of the belt conveyor through the fixing frame, and the bottom surface of the sealing roller contacts the belt of the belt conveyor; the end side sealing plate is fixed on the frame of the belt conveyor, and the outer shape of the end side sealing plate corresponds to the outer shape of the sealing roller, so that a small gap is maintained between the cleaning block and the sealing roller, and the sealing roller is a hollow capsule, which maintains dynamic sealing contact with the belt surface.

[0006] The sealing roller comprises an outer shell, a rotating shaft, a bearing and an air nozzle; the outer shell is made of rubber material, has an olive-shaped appearance, has a hollow inner cavity, has a bearing hole in the middle, and is provided with an air nozzle connected to the inner cavity; a bearing is fixed at each end of the bearing hole of the outer shell, the rotating shaft is fixedly inserted into the bearing hole and both ends pass through the inner hole of the bearing and are fixed on a fixing frame.

[0007] The present invention also includes a cleaning block, the inner side of which is fixed on the outer side wall of the end side sealing plate and the outer shape of the cleaning block corresponds to the outer shape of the sealing roller, so that a small gap is maintained between the cleaning block and the sealing roller.

[0008] After adopting the above scheme, since the present invention adopts a rotatable elastic sealing roller, the sealing roller is made of hollow capsules and maintains dynamic sealing contact with the belt surface. The linear speed of the main contact surface of the sealing roller is close to the linear speed of the belt surface, and there is basically no relative sliding wear; at the same time, when there is material adhering to the belt surface or the tail of the belt is manually fed, the sealing roller surface will be lifted up by the material and the material will pass through by itself. Furthermore, the end face and side face of the sealing roller are in contact with the wear-resistant cleaning strip, and the cleaning strip can clean the surface of the sealing roller and form a complete sealing interface with the contact surface of the belt; it has the following advantages: (1) dynamic non-wear sealing, continuous and reliable sealing, and good sealing effect; (2) materials can pass automatically; (3) it can adapt to various working conditions where the belt surface is not intact and will not scratch the belt joint; (4) the device has low running resistance; (5) no additional power is required; (6) the system is maintenance-free.

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] like Figure 1-Figure 4 As shown, the present invention is a belt conveyor tail sealing box, comprising a fixing frame 1, a sealing roller 2, an end side sealing plate 3, and a cleaning block 4.

[0015] Both ends of the sealing drum 2 are mounted on the frame 101 of the belt conveyor 10 through a fixing frame 1, and the bottom surface of the sealing drum 2 is in contact with the belt 102 of the belt conveyor 10; the end side sealing plate 3 is fixed on the frame 101 of the belt conveyor 10, the inner side of the cleaning block 4 is fixed on the outer side wall of the end side sealing plate 3, and the outer shape of the cleaning block 4 corresponds to the outer shape of the sealing drum 2, so that a small gap is maintained between the cleaning block 4 and the sealing drum 2; the outer side surface of the cleaning block 4 is in contact with the surface of the sealing drum 2, and the cleaning block 4 cleans the surface of the sealing drum 2; the sealing drum 2 is a hollow capsule, which maintains dynamic sealing contact with the belt surface 102, and the linear velocity of the main contact surface of the sealing drum 2 is close to the linear velocity of the belt 102 surface.

[0016] The sealing roller 2 comprises a housing 21, a rotating shaft 22, a bearing 23, and an air nozzle 24; the housing 21 is made of rubber material, has an olive shape, has a hollow inner cavity, has a bearing hole 211 in the middle, and is provided with an air nozzle 24 connected to the inner cavity. A bearing 23 is fixed at both ends of the bearing hole 211 of the housing 21, and the rotating shaft 22 is fixedly inserted in the bearing hole 211 and both ends pass through the inner hole of the bearing 23 and are fixed on the fixing frame 1.

[0017] Working principle of the present invention:

[0018] The sealing roller 2 is made of hollow capsules. When there is adhered material on the surface of the belt 102 or material is manually added to the tail of the belt 102, the surface of the sealing roller 2 will be lifted up by the material, and the material will pass into the sealing box by itself. It can be further cleaned by the internal cleaning mechanism, so that the adhered material on the working surface of the belt will not accumulate on the return journey, and the working environment will be more environmentally friendly.

[0019] The sealing plate 3 and the cleaning block 4 fixed on the end side cooperate with the sealing roller 2. At the same time, the sealing roller 2 maintains dynamic sealing contact with the belt 102 surface. The linear velocity of the main contact surface of the sealing roller 2 is close to the linear velocity of the belt 102 surface. There is basically no relative sliding wear, so that dynamic sealing is realized, the overall sealing effect is good, and dust leakage is avoided.

[0020] 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.
