Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium silicate board drying technology, specifically a calcium silicate board blank drying device. Background Technology
[0002] Calcium silicate boards are made from raw materials such as quartz sand, cement, and lime, and are produced under high temperature and pressure. If they are not fully dried, residual moisture inside the board will cause its strength to decrease, its bending resistance to weaken, and even problems such as deformation and cracking to occur after it becomes damp. During the drying process of calcium silicate boards, the drying temperature needs to be controlled, generally around 120℃. Too low a temperature will result in excessively long drying time and low production efficiency, while too high a temperature will cause problems such as thermal cracking and deformation of the calcium silicate boards. Therefore, precise control of the drying temperature is required.
[0003] Considering that the temperature during the drying process of calcium silicate board is usually around 120 degrees Celsius, the temperature is usually conducted from the outside of the calcium silicate board to the inside during drying. When the drying temperature is too high, the outside of the calcium silicate board may be completely dried while the inside is still not dried. This will cause an imbalance of internal and external pressure. If the calcium silicate board is dried further at this time, the internal moisture may evaporate but cannot be released, which may cause the calcium silicate board to deform from the inside out. Utility Model Content
[0004] The purpose of this invention is to provide a calcium silicate slab drying device to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a calcium silicate slab drying device, comprising a shell and a motor base. A first motor is fixedly connected to the top of the motor base, and a belt is driven to the output end of the first motor. A rotating shaft is driven to the end of the belt away from the first motor. There are multiple rotating shafts, and a conveyor belt is driven to the outer surface of the rotating shaft. Hanging rods are evenly fixedly connected to the outer surface of the conveyor belt, and a calcium silicate slab is placed between every two hanging rods. Motor slots are provided on both sides of the shell, and a motor frame is fixedly connected to the motor slot. A second motor is fixedly connected to the middle of the motor frame, and the output end of the second motor is fixedly connected to the rotating shaft near the middle. A vibration unit is fixedly connected to the inner bottom surface of the shell.
[0007] The vibration unit includes two support frames arranged symmetrically. A vibration plate is slidably connected to one side of the support frames that are close to each other. Multiple vibration modules are fixedly connected to one side of the support frames that are close to each other. The vibration modules are in contact with the vibration plate.
[0008] Furthermore, multiple return springs are fixedly connected between the vibrating plate and the support frame, and multiple sliding shafts are fixedly connected to the side of the vibrating plate near the support frame, with the sliding shafts slidably connected to the support plate.
[0009] Furthermore, multiple mounting grooves are provided on the adjacent side surface of the vibrating plate, and electromagnets are fixedly connected in each mounting groove. The magnetic poles of adjacent electromagnets are the same.
[0010] Furthermore, the surface of the sliding shaft is provided with multiple conductive grooves, and conductive contacts are fixedly connected in each conductive groove. The conductive contacts are electrically connected to the electromagnet.
[0011] Furthermore, a microwave heating plate is fixedly connected to the inner top surface of the outer shell.
[0012] Furthermore, a steam pipe is fixedly connected to one side of the outer shell, a sealing pipe is fixedly connected to the bottom of the steam pipe, a drain pipe is fixedly connected to the end of the sealing pipe away from the steam pipe, a water collection pipe is fixedly connected to the bottom of the drain pipe, and an automatic regulating valve is fixedly connected to the inner wall of the drain pipe and the steam pipe.
[0013] This utility model has the following beneficial effects:
[0014] 1. In the drying process of this utility model, the vibration module can be activated, and the vibration module will transmit the vibration to the conveyor belt through the vibration plate. When the conveyor belt is vibrated, it will transmit the vibration to the calcium silicate board. At this time, the calcium silicate board will promote the migration of moisture within the calcium silicate board through vibration, which can accelerate the diffusion of moisture, thereby making the drying more uniform and reducing the occurrence of uneven pressure inside and outside the calcium silicate board. At the same time, since the hanging rod separates each calcium silicate board, the calcium silicate boards will not collide with each other during the vibration process.
[0015] 2. This utility model features a reset spring that can reset the vibrating plate when it moves away from the vibration module and re-engage it with the vibration module. The sliding shaft can limit the position of the vibrating plate to prevent it from deviating from the vibration module, thus ensuring that the vibration module can continuously vibrate the vibrating plate.
[0016] 3. By incorporating an electromagnet, the vibrating plates can attract each other when they are close together. At this time, the attractive force of the electromagnet and the restoring force of the return spring can simultaneously pull the vibrating plate back to its original position. Thus, the vibrating plate can still be reset even when it fluctuates greatly. By incorporating conductive contacts, the voltage of the electromagnet can be adjusted by the contact of the conductive contacts, thereby controlling the magnitude of the attractive force of the electromagnet. When the vibrating plate is far from the vibration module, a larger attractive force can be used to reset the vibrating plate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4As shown, this utility model is a calcium silicate slab drying device, including a shell 1 and a motor base 11. A first motor 111 is fixedly connected to the top of the motor base 11. A belt 112 is driven to the output end of the first motor 111. A rotating shaft 113 is driven to the end of the belt 112 away from the first motor 111. There are multiple rotating shafts 113. A conveyor belt 114 is driven to the outer surface of the rotating shaft 113. Hanging rods 115 are evenly fixed to the outer surface of the conveyor belt 114. A calcium silicate slab is placed between every two hanging rods 115. Motor slots are opened on both sides of the shell 1. A motor frame 12 is fixedly connected to the motor slot. A second motor 13 is fixedly connected to the middle of the motor frame 12. The output end of the second motor 13 is fixedly connected to the rotating shaft 113 near the middle. A vibration unit 2 is fixedly connected to the inner bottom surface of the shell 1.
[0026] The vibration unit 2 includes two support frames 21, which are symmetrically arranged. A vibration plate 22 is slidably connected to one side of the support frame 21 that is close to each other. A plurality of vibration modules 23 are fixedly connected to one side of the support frame 21 that is close to each other. The vibration modules 23 are in contact with the vibration plate 22.
[0027] In this embodiment, considering that the temperature during the drying process of calcium silicate board is usually around 120 degrees Celsius, the temperature is usually conducted from the outside of the calcium silicate board to the inside during drying. When the drying temperature is high, the outside of the calcium silicate board may be completely dried while the inside of the calcium silicate board is still not dried. This will lead to an imbalance of internal and external pressure. If the calcium silicate board is dried again at this time, the internal moisture may evaporate but cannot be released, and the calcium silicate board may deform from the inside to the outside.
[0028] During drying, the calcium silicate board is first placed into the equipment from one side and then placed between the two hanging rods 115. At this time, starting the first motor 111 and the second motor 13 can make the rotating shaft 113 rotate. When the rotating shaft 113 rotates, it will drive the conveyor belt 114 to drive the transmission. When the conveyor belt 114 drives the transmission, it will drive the hanging rod 115 to move. When the hanging rod 115 moves, it can drive the calcium silicate board to move. At this time, the calcium silicate board can be dried by the high temperature inside the outer shell 1.
[0029] During the drying process, the vibration module 23 can be activated, and the vibration of the vibration module 23 is transmitted to the vibration plate 22. Then, the vibration of the vibration plate 22 is transmitted to the conveyor belt 114. When the conveyor belt 114 is vibrated, it will transmit the vibration to the calcium silicate board. At this time, the calcium silicate board will promote the migration of moisture in the calcium silicate board through vibration, which can accelerate the diffusion of moisture and make the drying more uniform, thereby reducing the occurrence of uneven pressure inside and outside the calcium silicate board. At the same time, since the hanging rod 115 separates each calcium silicate board, the calcium silicate boards will not collide with each other during the vibration process.
[0030] After drying, the calcium silicate board can be collected on the other side of the outer shell 1, thereby completing the drying process of the calcium silicate board.
[0031] Specifically, a plurality of return springs 222 are fixedly connected between the vibration plate 22 and the support frame 21, and a plurality of sliding shafts 221 are fixedly connected to the side of the vibration plate 22 near the support frame 21, and the sliding shafts 221 are slidably connected to the support plate.
[0032] In this embodiment, when the vibration module 23 drives the vibration plate 22 to vibrate, the vibration plate 22 may lose contact with the vibration module 23. This may cause the vibration module 23 to fail to vibrate the vibration plate 22 normally, and also cause the calcium silicate plate to fail to vibrate normally. At this time, the reset spring 222 is set so that when the vibration plate 22 moves away from the vibration module 23, the reset spring 222 can reset the vibration plate 22 and make it contact the vibration module 23 again. The sliding shaft 221 can limit the position of the vibration plate 22 to prevent the position of the vibration plate 22 from deviating from that of the vibration module 23, so as to ensure that the vibration module 23 can continuously vibrate the vibration plate 22.
[0033] Specifically, multiple mounting grooves are provided on the side surface of the vibrating plate 22 that are close to each other, and electromagnets 24 are fixedly connected in each mounting groove. The magnetic poles of the electromagnets 24 that are close to each other are the same.
[0034] In this embodiment, when there are too many calcium silicate boards on the conveyor belt 114, the conveyor belt 114 will exert greater pressure on the vibrating plate 22. At this time, it is necessary to increase the power of the vibration unit 2 to vibrate. With the setting of the electromagnet 24, the vibrating plates 22 can attract each other when they are close together. At this time, the attraction force of the electromagnet 24 and the rebound force of the return spring 222 can simultaneously pull the vibrating plate 22 to reset. Thus, the vibrating plate 22 can still be reset when the vibration plate 22 fluctuates greatly.
[0035] Specifically, the surface of the sliding shaft 221 is provided with multiple conductive grooves, and conductive contacts 223 are fixedly connected in each conductive groove. The conductive contacts 223 are electrically connected to the electromagnet 24.
[0036] In this embodiment, it is considered that when the vibrating plate 22 moves different distances due to vibration, the electromagnets 24 may not be able to attract each other because the attraction force is always the same.
[0037] By setting the conductive contact 223, the sliding shaft 221 can be moved when the vibrating plate 22 moves due to vibration. Different conductive contacts 223 are driven to contact the support frame 21. Since the conductive contact 223 is electrically connected to the electromagnet 24, the voltage of the electromagnet 24 can be adjusted by the contact of the conductive contact 223, thereby controlling the magnitude of the attraction force of the electromagnet 24. When the vibrating plate 22 is far from the vibration module 23, the vibrating plate 22 can be reset by a larger attraction force.
[0038] Specifically, a microwave heating plate 16 is fixedly connected to the inner top surface of the outer shell 1.
[0039] In this embodiment, the microwave heating plate 16 can be used for auxiliary heating during heating. Since microwave heating generates "internal friction heat" due to the high-frequency reciprocating motion of the dipole molecules inside the heated body, the temperature of the heated material will rise. At this time, the calcium silicate board can be heated and dried from the inside to the outside, thereby further ensuring the uniformity of the drying of the calcium silicate board.
[0040] Specifically, a steam pipe 14 is fixedly connected to one side of the outer casing 1, a sealing pipe 141 is fixedly connected to the bottom of the steam pipe 14, a drain pipe 142 is fixedly connected to the end of the sealing pipe 141 away from the steam pipe 14, a water collection pipe 144 is fixedly connected to the bottom of the drain pipe 142, and an automatic regulating valve 143 is fixedly connected to the inner wall of the drain pipe 142 and the steam pipe 14.
[0041] In this embodiment, considering that the moisture of the calcium silicate board will be evaporated during drying, a large amount of water vapor will be generated inside the outer shell 1. When the air humidity reaches saturation, the evaporation rate of water will be significantly reduced, which may result in the calcium silicate board not being completely dried.
[0042] When there is too much water vapor inside the outer casing 1, the water vapor can be discharged outward through the steam pipe 14. At this time, the water vapor will enter the sealing pipe 141 through the steam pipe 14. Some of the water vapor will condense into water in the sealing pipe 141, and some will enter the drain pipe 142 for discharge. When there is too much water in the sealing pipe 141, the steam will not be able to be discharged through the sealing pipe 141. At this time, the steam and water in the sealing pipe 141 can be discharged through the drain pipe 142 by opening the automatic regulating valve 143. Then the steam and water will enter the water collection pipe 144 for collection.
[0043] When using,
[0044] First, during the drying process, the calcium silicate board is placed into the equipment from one side and then positioned between the two hanging rods 115. At this time, starting the first motor 111 and the second motor 13 will cause the rotating shaft 113 to rotate. When the rotating shaft 113 rotates, it will drive the conveyor belt 114 to move. When the conveyor belt 114 moves, it will drive the hanging rods 115 to move. When the hanging rods 115 move, they will move the calcium silicate board. At this time, the calcium silicate board can be dried by the high temperature inside the outer shell 1.
[0045] By setting up the microwave heating plate 16, auxiliary heating can be carried out during heating. Since microwave heating will generate "internal friction heat" through the high-frequency reciprocating motion of the dipole molecules inside the heated body, the temperature of the heated material will rise. At this time, the calcium silicate board can be heated and dried from the inside to the outside, thereby further ensuring the uniformity of drying of the calcium silicate board.
[0046] During the drying process, the vibration module 23 can be activated, and the vibration of the vibration module 23 is transmitted to the vibration plate 22. Then, the vibration of the vibration plate 22 is transmitted to the conveyor belt 114. When the conveyor belt 114 is vibrated, it will transmit the vibration to the calcium silicate board. At this time, the calcium silicate board will promote the migration of moisture in the calcium silicate board through vibration, which can accelerate the diffusion of moisture and make the drying more uniform, thereby reducing the occurrence of uneven pressure inside and outside the calcium silicate board. At the same time, since the hanging rod 115 separates each calcium silicate board, the calcium silicate boards will not collide with each other during the vibration process.
[0047] Secondly, when the vibration module 23 drives the vibration plate 22 to vibrate, the vibration plate 22 may lose contact with the vibration module 23. This may cause the vibration module 23 to fail to vibrate the vibration plate 22 normally, and also cause the calcium silicate plate to fail to vibrate normally. At this time, the reset spring 222 is set to reset the vibration plate 22 when it moves away from the vibration module 23 and re-establish contact with the vibration module 23. The sliding shaft 221 can limit the position of the vibration plate 22 to prevent the position of the vibration plate 22 from deviating from that of the vibration module 23, so as to ensure that the vibration module 23 can continuously vibrate the vibration plate 22.
[0048] When there are too many calcium silicate boards on the conveyor belt 114, the conveyor belt 114 will exert a large pressure on the vibrating plate 22. At this time, the power of the vibration unit 2 needs to be increased to vibrate. With the setting of the electromagnet 24, the vibrating plates 22 can attract each other when they are close together. At this time, the attraction force of the electromagnet 24 and the rebound force of the return spring 222 can simultaneously pull the vibrating plate 22 to reset. Thus, the vibrating plate 22 can still be reset when the vibration plate 22 fluctuates greatly.
[0049] By setting the conductive contact 223, the sliding shaft 221 can be moved when the vibrating plate 22 moves due to vibration. Different conductive contacts 223 are driven to contact the support frame 21. Since the conductive contact 223 is electrically connected to the electromagnet 24, the voltage of the electromagnet 24 can be adjusted by the contact of the conductive contact 223, thereby controlling the magnitude of the attraction force of the electromagnet 24. When the vibrating plate 22 is far from the vibration module 23, the vibrating plate 22 can be reset by a larger attraction force.
[0050] Finally, when there is too much water vapor inside the outer casing 1, the water vapor can be discharged outward through the steam pipe 14. At this time, the water vapor will enter the sealing pipe 141 through the steam pipe 14. Some of the water vapor will condense into water in the sealing pipe 141, and some will enter the drain pipe 142 for discharge. When there is too much water in the sealing pipe 141, the steam will not be able to be discharged through the sealing pipe 141. At this time, the steam and water in the sealing pipe 141 can be discharged through the drain pipe 142 by opening the automatic regulating valve 143. At this time, the steam and water will enter the water collection pipe 144 for collection.
[0051] After drying, the calcium silicate board can be collected on the other side of the outer shell 1, thereby completing the drying process of the calcium silicate board.
