Description

Technical Field

[0001] This application relates to the technical field of glass production and manufacturing. Specifically, it relates to a blowing mechanism for tank wall bricks. Background Art

[0002] The raw materials required for glass manufacturing are stored in the silo. When feeding the raw materials into the kiln, the raw materials in the silo will fall onto the lower pallet. As the lower pallet moves backward, the scraper plate arranged above the lower pallet and in contact with the lower pallet pushes the raw materials on the lower pallet into the kiln. The lower pallet moves forward to guide the raw materials falling from the silo. During the feeding process, the lower pallet moves reciprocally, and the raw materials are fed more evenly under the guiding action of the lower pallet.

[0003] When adding raw materials into the kiln, due to the high temperature in the kiln and the impact of fire switching, fine powders are likely to fly and scatter during the operation of the feeder, and fall and accumulate on the surface of the tank wall bricks at the feeding port. It is necessary to clean the powders on the surface of the tank wall bricks manually. However, during the cleaning process, the powders fly, which affects the respiratory health of the staff, and the manual cleaning efficiency is slow. The temperature of the melting furnace is high, presenting potential safety hazards.

[0004] To prevent powders from scattering on the tank wall during the feeding process, some existing devices (for example: the authorized publication number is: CN 216785971U, and the name is: Dust collection and raw material recovery device for the tank wall bricks at the feeding port of a glass melting furnace) set multiple sub-air pipes on the main air pipe, and suction devices are arranged on the sub-air pipes. The suction devices face the tank wall bricks of the feeding tank. By means of the suction devices, the flying powders are prevented from adhering to the tank wall. However, after the powders are sucked away by such suction devices, the feeding ratio will be affected. Even if the sucked raw materials are re-fed into the kiln later, the feeding ratio in the early stage will be affected because the feeding time is late. Utility Model Content

[0028] Such as Figure 1 and Figure 2As shown in the figure, an air blowing mechanism for the pool wall bricks provided by the embodiment is arranged on the lower support plate structure 100 of the kiln. The lower support plate structure 100 includes a lower support plate 101 and a support frame 102. The lower support plate 101 is movably arranged on the support frame 102 in a reciprocating manner. One end of the support frame 102 is matched with the lower support plate 101, and the other end is arranged on the ground. The air blowing mechanism for the pool wall bricks includes: a support structure 10 and an air blowing structure 20. The support structure 10 is arranged on the lower support plate structure 100. The air blowing structure 20 is arranged on the support structure 10. The air blowing structure 20 faces the gap between the lower support plate 101 and the pool wall bricks 200. The air blowing structure 20 includes a first air pipe 21 and a second air pipe 22. The first air pipe 21 is sleeved on the circumferential outer side of the second air pipe 22. The first air pipe 21 has an air vent. The side wall of the second air pipe 22 has a plurality of air outlet holes 2211.

[0029] Applying the technical solution of this embodiment, the air blowing mechanism for the pool wall bricks is arranged on the lower support plate structure 100 of the kiln. The lower support plate structure 100 includes a lower support plate 101 and a support frame 102. The lower support plate 101 is movably arranged on the support frame 102 in a reciprocating manner. One end of the support frame 102 is matched with the lower support plate 101, and the other end is arranged on the ground. The air blowing mechanism for the pool wall bricks includes a support structure 10 and an air blowing structure 20. The support structure 10 is arranged on the lower support plate structure 100. The air blowing structure 20 is arranged on the support structure 10. The air blowing structure 20 faces the gap between the lower support plate 101 and the pool wall bricks 200. The air blowing structure 20 includes a first air pipe 21 and a second air pipe 22. The first air pipe 21 is sleeved on the circumferential outer side of the second air pipe 22. The first air pipe 21 has an air vent. The side wall of the second air pipe 22 has a plurality of air outlet holes 2211. The gas in the second air pipe 22 is discharged through the air outlet holes 2211, and then blown through the air vent into the gap between the lower support plate 101 and the pool wall bricks 200. The gas can timely blow the dust back, thereby avoiding the problem that the feeding ratio is inaccurate due to the powder being blown out. And after the gas enters the kiln from the gap, the gas is located between the powder and the pool wall bricks 200, which can effectively prevent the powder from adhering to the pool wall bricks 200. The technical solution of this embodiment effectively solves the problems of powder adhesion on the pool wall bricks 200 and affecting the feeding ratio when removing the powder in the prior art.

[0030] It should be noted that the air vent is a rectangular opening formed on the side wall of the first air pipe 21. The air vent faces the gap between the lower support plate 101 and the pool wall bricks 200. For the air outlet holes 2211 within the range of the air vent, the gas can directly flow from the air outlet holes 2211 to the air vent and then flow out. For the air outlet holes 2211 outside the range of the air vent, affected by the side wall of the first air pipe 21, the gas cannot directly flow out. The gas flows from the gap between the first air pipe 21 and the second air pipe 22 to the air vent and then flows out.

[0031] Such as Figure 1 and Figure 2As shown, in some embodiments, the support structure 10 includes a rack 11. The rack 11 is arranged on the lower support plate 101. As the lower support plate 101 reciprocates, the lower support plate 101 drives the rack 11 to reciprocate synchronously. The outer wall of the first air pipe 21 is provided with teeth 211 along the circumferential direction. The teeth 211 mesh with the rack 11. As the rack 11 reciprocates, the first air pipe 21 deflects reciprocally. This enables the gas flowing out from the ventilation port to deflect when blowing towards the gap. Such a setting can achieve a good purging effect. When the first air pipe 21 deflects clockwise to the maximum angle value, the gas blown out at this time can form an air curtain above the pool wall brick 200, preventing the gas from rising out from above, and part of the gas is blown back into the kiln under the rebounding action of the lower support plate 101, which can accelerate the melting rate of the powder material. When the first air pipe 21 deflects counterclockwise to the maximum angle value, the gas blown out at this time enters the kiln along the pool wall brick 200, and the gas is located between the pool wall brick 200 and the falling powder material, which can prevent the powder material from adhering to the surface of the pool wall brick 200.

[0032] As Figure 3 shown, in some embodiments, the second air pipe 22 has a purging section 221, a first connection section 222 and a second connection section 223. The purging section 221 is located between the first connection section 222 and the second connection section 223. The first connection section 222 and the second connection section 223 are used for connection and fixation. The purging section 221 is used for storing gas. The first air pipe 21 is sleeved on the circumferential outer side of the purging section 221. A plurality of air outlet holes 2211 are all located on the side wall of the purging section 221. The gas stored in the purging section 221 flows through the air outlet holes 2211 and is discharged through the ventilation port.

[0033] As Figure 2 shown, in some embodiments, the support structure 10 further includes two groups of support rods 12. The first ends of the two groups of support rods 12 are both connected to the support frame 102. There are two groups of support frames 102, which are respectively arranged at both ends of the lower support plate 101. The two groups of support rods 12 are respectively connected to the two groups of support frames 102 in a one-to-one correspondence. The second ends of the two groups of support rods 12 are respectively connected to the first connection section 222 and the second connection section 223 to realize the fixation of the second air pipe 22.

[0034] As Figure 3As shown, in some embodiments, the purging structure 20 further includes a gas delivery pipeline 23 and a gas source. The first end of the first connection section 222 is in communication with the purging section 221, the second end of the first connection section 222 is sealed, the first end of the second connection section 223 is in communication with the purging section 221, the second end of the second connection section 223 is sealed, the side wall of the second connection section 223 is in communication with the first end of the gas delivery pipeline 23, the second end of the gas delivery pipeline 23 is in communication with the gas source. The gas in the gas source flows through the gas delivery pipeline 23 to the second connection section 223. The second connection section 223 is in communication with the purging section 221, and the purging section 221 is in communication with the first connection section 222. The gas fills the purging section 221, the first connection section 222, and the second connection section 223.

[0035] It should be noted that the purging structure 20 further includes an air heater. The air heater is arranged on the gas delivery pipeline 23 and is in communication with the gas delivery pipeline 23. The heating element of the air heater is a stainless steel electric heating tube. A plurality of baffle plates are arranged in the air heater to guide the gas flow direction and extend the gas residence time. The air heater can fully heat the gas so that when the gas blows into the kiln, the temperature in the kiln will not fluctuate greatly.

[0036] In some embodiments, the purging structure 20 further includes a bearing and two sets of sealing rings. The bearing is sleeved on the circumferential outer side of the second air pipe 22, and the first air pipe 21 is sleeved on the circumferential outer side of the bearing. The bearing makes the deflection of the first air pipe 21 smoother. At the same time, there is a spacing distance between the first air pipe 21 and the second air pipe 22. The gas can also flow out from the air holes 2211 on the purging section 221 that do not correspond to the vent holes, and then converge to the vent hole through the gap between the first air pipe 21 and the second air pipe 22. The inner circles of the two sets of sealing rings are respectively sleeved on the circumferential outer sides of the first connection section 222 and the second connection section 223, and the outer circles of the two sets of sealing rings are respectively connected to the two ends of the first air pipe 21. The sealing rings prevent the gas from flowing out from the two ends of the first air pipe 21 and do not easily affect the gas output of the vent hole. There is a spacing distance between the two sets of sealing rings and the outer walls of the first connection section 222 and the second connection section 223. This setting method aims to neither affect the exhaust volume of the vent hole nor affect the deflection of the first air pipe 21. The two sets of sealing rings can be made of rubber or plastic.

[0037] Such as Figure 1 and Figure 4As shown, in some embodiments, the purging structure 20 further includes a jet nozzle 24 disposed on the outer wall of the first air pipe 21. The jet nozzle 24 is in communication with the vent port. The jet nozzle 24 includes a first mating plate 241, a second mating plate 242, a third mating plate 243, and a fourth mating plate 244. The first mating plate 241 and the second mating plate 242 are disposed opposite to each other. The third mating plate 243 and the fourth mating plate 244 are disposed opposite to each other. The first mating plate 241 is connected to the third mating plate 243 and the fourth mating plate 244. The second mating plate 242 is connected to the third mating plate 243 and the fourth mating plate 244. The first ends of the first mating plate 241 and the second mating plate 242 are both connected to the outer wall of the first air pipe 21. The second ends of the first mating plate 241 and the second mating plate 242 approach each other in a direction away from the vent port. The first ends of the third mating plate 243 and the fourth mating plate 244 are both connected to the outer wall of the first air pipe 21. The second ends of the third mating plate 243 and the fourth mating plate 244 approach each other in a direction away from the vent port. The purpose of this arrangement is that when the gas is ejected from the jet nozzle 24, the flow velocity of the gas is enhanced, so the flow distance of the gas is farther, and the surface of the cell wall brick 200 can be well protected.

[0038] In some embodiments, a valve is provided on the gas transmission pipeline 23, and the valve can control the amount of gas input from the gas transmission pipeline 23 into the second air pipe 22.

[0039] In some embodiments, a filter screen is provided at the vent port, and the filter screen can prevent impurities in the external environment from entering the second air pipe 22 through the vent port and blocking the air outlet holes 2211, which affects the purging effect.
