Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tail gas filtering equipment, in particular to a rock wool production line tail gas filtering device. BACKGROUND

[0002] In the rock wool production process, a large amount of tail gas containing fine fibers, dust and harmful gas will be generated after the high-temperature molten raw material is centrifuged into fibers. If these tail gases are directly discharged, not only will it cause serious air pollution, harm the surrounding environment and human health, but also will affect the normal operation of the equipment in the factory area due to the scattering of fibers. Therefore, the tail gas filtering device as the key environmental protection equipment of the rock wool production line, its filtering efficiency is directly related to the environmental protection standard and sustainability of production.

[0003] At present, the rock wool production line tail gas filtering device on the market has obvious technical defects. The existing device mostly uses a fixed fiber filter screen for filtering. Although it can intercept some fibers and dust, it has many problems in long-term use. Because the fibers in the rock wool tail gas are light and have certain viscosity, they are easy to accumulate on the surface of the filter screen. The fixed filter screen cannot change the contact state with the tail gas by itself, and as the filtering time is prolonged, the fibers will gradually block the filter screen pores, resulting in increased filtering resistance, decreased tail gas flow, and rapidly deteriorated filtering effect. In addition, the stationary filter screen has limitations in capturing fibers in the tail gas. During the flow of the tail gas, fibers are easy to concentrate and adhere in the local area of the filter screen, while other areas do not fully play the filtering role, resulting in low utilization rate of the filter screen. In order to maintain the filtering effect, the enterprise needs to frequently stop production for cleaning or replace the filter screen, which not only increases the labor cost and equipment maintenance time, but also interrupts the production process and reduces the production efficiency. At the same time, if the cleaning is not timely, the unfiltered fibers may be discharged with the tail gas, causing environmental protection risks. Therefore, it is urgent to improve. SUMMARY

[0039] When the fiber filter screen 12 rotates, the cleaning roller 19 in contact with the fiber filter screen 12 also rotates, and the rotating cleaning roller 19 winds the fibers filtered on the surface of the fiber filter screen 12 on the surface of the cleaning roller 19, so that the fibers on the surface of the fiber filter screen 12 are timely removed; By arranging a plurality of cleaning rollers 19, the fiber filter screen 12 can drive the cleaning roller 19 in contact with it to rotate when the fiber filter screen 12 rotates, so that the cleaning roller 19 can remove the fibers on the surface of the fiber filter screen 12, thereby avoiding the accumulation of too many fibers on the surface of the fiber filter screen 12, which reduces the filtering effect of the fiber filter screen 12 on the fibers.

[0040] When the cleaning roller 19 winds and removes the fibers on the surface of the fiber filter screen 12, the control device 2 controls the second motor 24 to start, so that the connecting shaft 25 fixedly connected with the output end of the second motor 24 rotates, and in turn drives the screw rod 26 fixedly connected with the connecting shaft 25 to rotate, and through the threaded transmission cooperation between the screw rod 26 and the longitudinal block 27, the longitudinal block 27 slides in the longitudinal groove 23, and in turn drives the arc-shaped cleaning block 28 fixedly connected with the longitudinal block 27 to slide on the surface of each cleaning roller 19, so that the fibers on the surface of each cleaning roller 19 are removed, and the removed fibers fall into the first channel 20 below and are discharged from the filter frame 1.

[0041] A particle filtering mechanism is arranged between the fiber filter screen 12 and the exhaust pipe 6, and the particle filtering mechanism comprises: The second ring plate 29 is located between the exhaust pipe 6 and the fiber filter screen 12 and is fixedly connected with the filter frame 1, four vibration grooves 30 symmetrically distributed in pairs are formed in the second ring plate 29, and an inner cavity 31 is formed between the four vibration grooves 30; The particle filter screen 32 is arranged on the second ring plate 29, and the particle filter screen 32 is used for filtering the particle impurities in the tail gas; The second channel 33 is located between the particle filter screen 32 and the fiber filter screen 12, and the second channel 33 is fixedly connected with the filter frame 1, and the second channel 33 is used for discharging the particles filtered by the particle filter screen 32 from the filter frame 1. The connecting block 34 has four, and the four connecting blocks 34 are respectively slidably arranged in the four built-in cavities 31, and the connecting block 34 is fixedly connected with the particle filter screen 32; The fixed part has four groups, and the four groups of fixed parts are located in the vibration groove 30, and the fixed part includes: The fixed rod 35 is located in the vibration groove 30 and is fixedly connected with the second ring plate 29; The vibration plate 36 is located in the vibration groove 30 and is fixedly connected with the particle filter screen 32, and the vibration plate 36 is slidably connected with the fixed rod 35; The vibration spring 37 has two, and the two vibration springs 37 are respectively symmetrically sleeved on the fixed rod 35, and the vibration spring 37 is always in a compressed state.

[0042] When the particle filter screen 32 vibrates, the vibration plate 36 fixedly connected with the particle filter screen 32 vibrates in the vibration groove 30, so that the vibration spring 37 on both sides of the vibration plate 36 repeatedly deforms, thereby absorbing part of the energy of the vibration of the vibration plate 36, avoiding the vibration of the particle filter screen 32 fixedly connected with the vibration plate 36 being too violent to cause damage to the particle filter screen 32.

[0044] After the exhaust gas passing through the fiber filter screen 12 passes through the particle filter screen 32, it is discharged from the filter frame 1 through the exhaust pipe 6. While the particle filter screen 32 filters the particles in the exhaust gas, the vibration motor 39 is started by controlling the control device 2, so that the connecting block 34 fixedly connected with the output end of the vibration motor 39 vibrates in the built-in cavity 31, so that the particle filter screen 32 fixedly connected with the connecting block 34 vibrates, thereby causing the particles filtered by the surface of the particle filter screen 32 to fall off, and the fallen particles fall into the second channel 33 below and are discharged from the filter frame 1.
