Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dehumidification equipment, in particular to a rotary dehumidifier for high-temperature environment suitable for magnesite-carbon brick production and a dehumidification method. BACKGROUND

[0002] Magnesite-carbon brick is a high-performance refractory material made of magnesia material and carbon material as the core, through the synergistic effect of a binder and an antioxidant. The core raw material of magnesite-carbon brick is sensitive to humidity, and high humidity will directly damage its performance. For example, magnesite, as one of the raw materials, has a certain hygroscopicity and will absorb moisture in the air in a high-humidity environment, resulting in the formation of a water film on the surface of the particles. This not only causes the fine powder to clump, but also may produce pores due to water evaporation during subsequent high-temperature use, reducing the density and corrosion resistance of the green body. Therefore, strict dehumidification of the production environment is required during the production of magnesite-carbon brick to ensure production quality. However, the production process of magnesite-carbon brick results in an environment temperature in a high-temperature state, which in turn causes the temperature of the air to be dehumidified to be relatively high. When high-temperature air enters the rotary dehumidifier, the kinetic energy of water molecules on the surface of the rotary adsorbent material increases, which in turn easily desorbs, reducing the adsorption effect.

[0003] The rotary dehumidifier in the traditional technology has the problem of poor adsorption effect when applied in the production of magnesite-carbon brick, as described above. In addition, the rotary dehumidifier has a large cross-sectional area due to its large disc structure, and the rotational speed is relatively slow. The part of the rotary dehumidifier that has just completed regeneration has good moisture absorption effect, while the part that is about to enter the regeneration area has poor moisture absorption effect due to having been in the moisture absorption state for a period of time and being in a near-saturated state. When air passes through the rotary dehumidifier with a large cross-sectional area, it passes through different areas of the rotary dehumidifier, resulting in inconsistent uniformity of the dehumidified air, and the problem of poor uniformity of the dehumidified air. SUMMARY

[0004] The present application aims to provide a rotary dehumidifier for high-temperature environment suitable for magnesite-carbon brick production and a dehumidification method to solve the problem of poor adsorption effect and poor dehumidification uniformity of the rotary dehumidifier in the traditional technology when applied in the production of magnesite-carbon brick.

A back-and-forth dynamic shaft is arranged between the first sealing window plate and the second sealing window plate. A middle block is fixedly arranged at the middle position of the back-and-forth dynamic shaft. Two pressure plate springs are symmetrically arranged on both sides of the middle block, and the two groups of pressure plate springs respectively apply elastic pressure to the first sealing window plate and the second sealing window plate away from the direction of the middle block.

[0013] One end of the back-and-forth dynamic shaft is fixedly provided with a limiting end, and the other end is fixedly provided with a limiting link end. A connecting swing arm is swingingly connected to the limiting link end.

[0014] The inside of the dehumidifier cabinet body is also provided with a speed reduction gear disc, the other end of the connecting swing arm is swing connected with the eccentric position of the speed reduction gear disc, when the speed reduction gear disc rotates, it can drive the back and forth dynamic shaft to move axially reciprocatingly.

[0015] The outside of the speed reduction gear disc is provided with a driving pinion, the driving pinion is coaxially fixedly provided with a cam part, one side of the cam part is provided with a squeeze air pump, when the cam part rotates, it can intermittently squeeze the squeeze air pump, so that the squeeze air pump generates positive pressure gas.

[0016] The outside of the squeeze air pump is communicated with a buffer gas tank, the squeeze air pump outputs the positive pressure gas into the buffer gas tank, the buffer gas tank is communicated with an output air pipe, a continuous pressure relief valve and an exhaust valve, when the gas pressure in the buffer gas tank exceeds a set value, the gas is discharged through the continuous pressure relief valve.

[0017] The speed closing ring is fixedly provided with a cylinder unit, one side of the speed closing ring is provided with a tension spring, the other end of the tension spring is fixedly connected with the inner wall surface of the runner ring cover, the elastic pressure is provided through the tension spring, so that the cylinder unit is in a fully retracted state, at this time, the speed closing ring is closed corresponding to the striding through groove, and the cylinder unit is communicated with the output air pipe through an air pipe.

[0018] When the inside of the buffer gas tank is under positive pressure, the gas in the buffer gas tank enters the cylinder unit, so that the cylinder unit stretches out by overcoming the elastic tension provided by the tension spring, and then the speed closing ring is staggered with the position of the striding through groove, and the striding through groove is opened.

[0019] A dehumidification method suitable for high-temperature environment of magnesite carbon brick production, the method adopts a runner dehumidifier, and comprises the following steps:

[0020] Step one, the gas in the magnesite carbon brick production environment is first cooled through a surface cooler unit;

[0021] Step two, the first runner and the second runner are controlled to rotate, and the rotating directions are opposite;

[0022] Step three, the cooled gas in step one is sequentially dehumidified through the second runner and the first runner.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] 1、The runner dehumidifier of the present application is suitable for the high-temperature environment of magnesite carbon brick production, the air in the high-temperature environment is pre-cooled through the set surface cooler unit, the air temperature entering the runner is reduced, a lower temperature environment more conducive to moisture absorption is created for the adsorbent material, and the moisture absorption amount per unit time is improved; and the first runner and the second runner are coaxially arranged and reversely rotate, so that the uniformity of air dehumidification can be greatly improved.

[0025] 2. By combining the structure of the cross-flow channel, the first window and the second window, the present invention enables the rotary dehumidifier to enter a low-power state when the air humidity is low. In the low-power state, the cross-flow channel is continuously open, while the first window and the second window are opened alternately, so that the air to be dehumidified alternately bypasses the first and second rotors, thereby greatly reducing the resistance of the air passing through the rotors, reducing the power consumption of the equipment, and at the same time enabling the bypassed rotors to reduce dehumidification work and perform deep circulation regeneration.

[0026] 3. This invention, through the combination of a pneumatic hybrid control component and structures such as a quick-closing sealing ring, a first sealing plate, and a second sealing plate, can simultaneously drive the quick-closing sealing ring to move axially and open by generating positive pressure gas while driving the first and second sealing plates to open alternately. Alternating control and automatic opening of the quick-closing sealing ring can be achieved simply by energizing the motor. Furthermore, when the rotary dehumidifier detects an increase in the humidity of the incoming air, it can quickly close the quick-closing sealing ring by depressurizing, thereby quickly exiting the low-power state. This allows high-humidity air to pass through both the first and second rotary wheels simultaneously, improving the dehumidification effect. Attached Figure Description

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0040] Please refer to Figures 1 to 11 The present application provides a technical solution: a runner dehumidifier, comprising a dehumidifier cabinet 1 and a runner ring cover 2, as Figure 3 shown in the figure, the runner ring cover 2 is in the middle position of the dehumidifier cabinet 1, and the runner ring cover 2 is welded and fixed with the dehumidifier cabinet 1.

[0041] The runner ring cover 2 is provided with a first runner 3 and a second runner 4, which can be made of adsorption medium material such as silica gel, etc., with good physical and chemical stability, always keeping solid state in the adsorption process, even at high temperature of 100℃, the runner surface can keep no dewing, and there is no corrosion to the surrounding equipment.

[0042] The first runner 3 and the second runner 4 are coaxial and corresponding, and a gap is reserved between the first runner 3 and the second runner 4; as Figure 5As shown in the figure, the first runner 3 and the second runner 4 are respectively rotated by the corresponding power assembly, which comprises a speed reducer 108, a runner motor 109 and a transmission belt 110, all of which are arranged inside the dehumidifier cabinet 1, the runner motor 109 is in transmission connection with the speed reducer 108, the output high speed of the runner motor 109 is adjusted to a low speed high torque rotating power by the speed reducer 108, and then the rotating power drives the corresponding second runner 4 or first runner 3 to rotate through the transmission belt 110.

[0043] A receiving cover 6 is arranged in the above-mentioned reserved gap and fixedly matched with the runner ring cover 2, the two sides of the receiving cover 6 are respectively in sealing contact with the first runner 3 and the second runner 4 to avoid air leakage. The side of the first runner 3 and the second runner 4 away from the receiving cover 6 is respectively provided with a regeneration cover 5, and the regeneration cover 5 is also respectively in sealing contact with the first runner 3 and the second runner 4. Through the cooperation of the regeneration cover 5 and the receiving cover 6, a sealed area independent of the dehumidifier cabinet 1 is formed, so that the regeneration heating gas can enter the first runner 3 through the regeneration cover 5 at one side, then enter the second runner 4 through the receiving cover 6, and finally be discharged into the regeneration cover 5 at the other side, thereby completing the regeneration of the first runner 3 and the second runner 4. Figure 3 As shown in the figure, the dehumidifier cabinet 1 is integrally assembled with a regeneration heating bin 101 and an air induction bin 102, the regeneration heating bin 101 is provided with a regeneration air inlet pipe 103, and the air induction bin 102 is provided with a humidity discharge pipe 104. The inside of the regeneration heating bin 101 is provided with an air heating device, which is composed of a conventional electric heating wire, an electric heating fin and the like, and can heat the air to about 100 degrees.

[0044] The inside of the air induction bin 102 is provided with an air induction fan device, which can suck the external air into the regeneration heating bin 101 through the regeneration air inlet pipe 103 when the air induction fan device works, and heat the air to form high-temperature gas through the air heating device. The high-temperature gas enters the regeneration area of the first runner 3 through the regeneration cover 5, and then enters the regeneration area of the second runner 4 through the receiving cover 6, thereby performing the regeneration and dehumidification of the first runner 3 and the second runner 4 by the high-temperature gas. Finally, the high-temperature and high-humidity air enters the air induction bin 102 and is discharged to the outdoor area through the humidity discharge pipe 104.

[0045] The rotation directions of the first runner 3 and the second runner 4 are opposite, and the inside of the dehumidifier cabinet 1 is provided with a surface cooler unit 7, which is a surface cooler in the prior art and is composed of a refrigerating machine and a heat exchange fin, and can cool the passing air. The gas first passes through the surface cooler unit 7 and then sequentially passes through the second runner 4 and the first runner 3 to complete the dehumidification. Specifically, Figure 3As shown in the figure, the drying outlet pipe 105 and the processing inlet pipe 106 are respectively welded and communicated at both ends of the dehumidifier cabinet body 1, and the dehumidification fan 107 is installed in the inside of the dehumidifier cabinet body 1, when the dehumidification fan 107 works, the air flow is driven to enter the inside of the dehumidifier cabinet body 1 through the processing inlet pipe 106, then sequentially passes through the surface cooler unit 7, the second rotating wheel 4 and the first rotating wheel 3, and finally is discharged to the outside through the drying outlet pipe 105. The air to be dehumidified is communicated with the processing inlet pipe 106, and the dehumidified air is output through the drying outlet pipe 105.

[0046] The rotating wheel dehumidifier in the prior art has the problem of poor dehumidification uniformity, and the specific principle is as shown in the figure. Figure 1 As shown in the figure, the rotating wheel rotates slowly during work, and the rotating wheel circulates through the regeneration area to complete the dehumidification and regeneration, thereby circulating the moisture absorption. Figure 1 The rotating wheel shown in the figure rotates counterclockwise, and when rotating counterclockwise, the rotating wheel just moved out of the regeneration area is in an extremely low humidity state, which is a high-efficiency moisture absorption area, and after a period of moisture absorption, before entering the regeneration area, the part of the rotating wheel has been in a near-saturation state, which is a low-efficiency moisture absorption area. In addition, the radius of the rotating wheel is large, and the cross-sectional area is large, so when the air passes through the rotating wheel, it passes through the high-efficiency moisture absorption area and the low-efficiency moisture absorption area, thereby causing the problem of uneven dehumidification, and the humidity distribution uniformity of the discharged air is poor.

[0047] And the present application is as shown in the figure. Figure 3 As shown in the figure, the rotating wheel is divided into two parts inside the rotating wheel ring cover 2, which are the first rotating wheel 3 and the second rotating wheel 4, and the first rotating wheel 3 and the second rotating wheel 4 rotate in opposite directions, and the high-temperature air of the regeneration area is received by the supporting cover 6, so that the first rotating wheel 3 and the second rotating wheel 4 can complete synchronous regeneration during opposite rotation.

[0048] In the above process, since the first rotating wheel 3 and the second rotating wheel 4 are coaxially arranged and rotate in opposite directions, the high-efficiency moisture absorption area of the first rotating wheel 3 corresponds to the low-efficiency moisture absorption area of the second rotating wheel 4, and vice versa, and the high-efficiency moisture absorption area of the second rotating wheel 4 corresponds to the low-efficiency moisture absorption area of the first rotating wheel 3. At this time, when the air to be dehumidified passes through the second rotating wheel 4 and the first rotating wheel 3 to complete dehumidification, the dehumidification effect is more uniform, and the omission of only passing through the low-efficiency moisture absorption area is reduced.

[0049] The rotating wheel ring cover 2 is a hollow structure, which is arranged outside the first rotating wheel 3 and the second rotating wheel 4, and the inner surface of the rotating wheel ring cover 2 is in gas seal contact with the outer surface of the first rotating wheel 3 and the second rotating wheel 4, that is, the gas seal contact is realized by the gas seal structure; the inner surface of the rotating wheel ring cover 2 is provided with a cross-through groove 201, and the cross-through groove 201 corresponds to the reserved gap position between the first rotating wheel 3 and the second rotating wheel 4, as shown in the figure. Figure 6As shown in the middle, the straight angle area covered by the receiving mask 6 is not provided with a cross-through groove 201, so as to avoid the regenerative heating gas from escaping to the inside of the runner ring cover 2 through the cross-through groove 201.

[0050] The inside of the runner ring cover 2 is provided with a quick closing sealing ring 202, which is in sealing contact with the inner wall surface of the runner ring cover 2. When the quick closing sealing ring 202 slides to the corresponding position of the cross-through groove 201, the cross-through groove 201 can be closed. The first window 203 is provided on one side surface of the runner ring cover 2, and the second window 204 is provided on the other side surface. The first window 203 is provided with a first window sealing plate 205 for controlling the opening and closing of the first window 203. The second window 204 is provided with a second window sealing plate 206 for controlling the opening and closing of the second window 204.

[0051] The inside and outside of the runner ring cover 2 are provided with a pneumatic mixing control assembly. In the working process, the pneumatic mixing control assembly can automatically control the movement of the quick closing sealing ring 202, thereby realizing the opening of the cross-through groove 201, and then making the first window sealing plate 205 and the second window sealing plate 206 open alternately.

[0052] The inside of the dehumidifier cabinet 1 is fixedly provided with a track shaft 207, which penetrates through the first window sealing plate 205 and the second window sealing plate 206 to position and support the two. A back-and-forth dynamic shaft 208 is provided between the first window sealing plate 205 and the second window sealing plate 206. A middle blocking section 209 is fixedly arranged at the middle position of the back-and-forth dynamic shaft 208. Pressure plate springs 210 are symmetrically arranged on both sides of the middle blocking section 209. Two groups of pressure plate springs 210 respectively apply elastic pressure to the first window sealing plate 205 and the second window sealing plate 206 in the direction away from the middle blocking section 209.

[0053] The back-and-forth dynamic shaft 208 is fixedly provided with a limiting end 211 at one end and a limiting link end 212 at the other end. A connecting swing arm 213 is swingingly connected to the limiting link end 212. The inside of the dehumidifier cabinet 1 is also rotatably provided with a speed reduction gear disc 214. The other end of the connecting swing arm 213 is swingingly connected to the eccentric position of the speed reduction gear disc 214. When the speed reduction gear disc 214 rotates, it can drive the back-and-forth dynamic shaft 208 to move axially and reciprocally. The speed reduction gear disc 214 is externally meshed with a driving pinion 215. A cam portion 216 is coaxially fixedly arranged on the driving pinion 215. Figure 9As shown in the figure, a motor bracket 111 is fixedly installed on the inner lower surface of the dehumidifier cabinet body 1, a state switching motor 112 is fixedly assembled on the motor bracket 111, the motor shaft of the state switching motor 112 is fixedly installed with the driving pinion 215 and the cam portion 216 through the key groove, so that the driving pinion 215 and the cam portion 216 can be driven to rotate by the state switching motor 112. One side of the cam portion 216 is provided with a squeeze air pump 217, which can be intermittently squeezed with the cam portion 216 when the cam portion 216 rotates, so as to make the squeeze air pump 217 generate positive pressure gas.

[0054] The squeeze air pump 217 can generate positive pressure gas through intermittent squeezing and output externally. The specific structure of the squeeze air pump 217 includes a cylinder piston assembly, two groups of one-way valves, and a reset spring structure. The piston is elastically reset by the reset spring, and the reciprocating movement of the piston is realized by cooperating with intermittent squeezing. The two groups of one-way valves are used to make the gas directional drive and complete the output of the positive pressure gas. This will not be described in detail in this application.

[0055] The outside of the squeeze air pump 217 is provided with a buffer gas tank 218. The squeeze air pump 217 outputs the positive pressure gas into the buffer gas tank 218. The buffer gas tank 218 is provided with an output air pipe 219, a continuous pressure relief valve 220 and an exhaust valve 221 in communication. When the gas pressure in the buffer gas tank 218 exceeds the set value, the gas is discharged through the continuous pressure relief valve 220. The cylinder unit 222 is fixedly arranged on the quick closing ring 202. One side of the quick closing ring 202 is provided with a tension spring 223, the other end of the tension spring 223 is fixedly connected with the inner wall surface of the runner ring cover 2, and the elastic pressure is provided by the tension spring 223, so that the cylinder unit 222 is in a completely retracted state. At this time, the quick closing ring 202 is closed corresponding to the striding through slot 201, and the cylinder unit 222 is communicated with the output air pipe 219 through the air pipe.

[0056] When the inside of the buffer gas tank 218 is under positive pressure, the gas in the buffer gas tank 218 enters the cylinder unit 222, so that the cylinder unit 222 stretches out against the elastic tension provided by the tension spring 223, and then the quick closing ring 202 is misaligned with the position of the striding through slot 201, and the striding through slot 201 is opened.

[0057] A dehumidification method suitable for high-temperature environment of magnesite carbon brick production, which adopts a runner dehumidifier, including the following steps:

[0058] Step one, the gas in the magnesite carbon brick production environment first passes through the surface cooler unit 7 to complete the cooling;

[0059] Step two, control the first runner 3 and the second runner 4 to rotate, and the rotating directions are opposite;

[0060] Step three, the cooled gas in step one passes through the second runner 4 and the first runner 3 in turn for dehumidification.

[0061] The present application is provided with the surface cooler unit 7, so that the air is cooled by the surface cooler unit 7 before being dehumidified, and since the core of the runner is an adsorbent material, its moisture absorption capacity is closely related to the air temperature, and after being cooled by the surface cooler unit 7, it is sequentially dehumidified by the second runner 4 and the first runner 3, which can create a low-temperature environment more conducive to moisture absorption for the adsorbent material, increase the moisture absorption amount per unit time, and thus better adapt to the high-temperature environment of the magnesite-carbon brick production.

[0062] The present application is provided with the surface cooler unit 7 and the second runner 4, and a humidity sensor is arranged in the area range between the surface cooler unit 7 and the second runner 4. When the air humidity is detected to be reduced to a set threshold, the driving pinion 215 is driven to rotate. Figure 9 and Figure 11 As shown in FIGS. 1, 2 and 3, when the driving pinion 215 rotates, the cam portion 216 rotates synchronously. During the rotation of the driving pinion 215, since the gear diameter of the driving pinion 215 is much smaller than that of the speed reduction gear disc 214, the speed reduction gear disc 214 is driven to rotate at a low speed and high torque by engaging with the speed reduction gear disc 214.

[0063] The swing connection of the connecting swing arm 213 enables the speed reduction gear disc 214 to drive the reciprocating dynamic shaft 208 to axially reciprocate during rotation of the speed reduction gear disc 214. Taking the right axial movement of the reciprocating dynamic shaft 208 as an example, during the continuous right movement of the reciprocating dynamic shaft 208, the pressing plate spring 210 between the second sealing window plate 206 and the middle blocking section 209 is continuously compressed, the second sealing window plate 206 remains closed, and when the limiting end 211 contacts the first sealing window plate 205, the first sealing window plate 205 is separated from the first window 203 as the reciprocating dynamic shaft 208 moves to the right, thereby opening the first window 203. Conversely, when the reciprocating dynamic shaft 208 moves to the left, the first sealing window plate 205 remains closed, and the second sealing window plate 206 is driven to move out of the second window 204 to open, thereby enabling the first window 203 and the second window 204 to be alternately opened when the driving pinion 215 rotates.

[0064] During the above process, the cam portion 216 rotates, the extrusion air pump 217 is intermittently extruded by the cam portion 216, the extrusion air pump 217 generates positive pressure gas, and the positive pressure gas is input into the buffer gas tank 218, so that the gas pressure in the buffer gas tank 218 gradually increases. Since the output air pipe 219 is in communication with the air cylinder unit 222 through the air pipe, the gas in the buffer gas tank 218 enters the air cylinder unit 222 through the air pipe, and the air cylinder unit 222 is gradually extended. During this process, the quick closing sealing ring 202 moves to the left, the cross-slot 201 is opened, and the tension spring 223 is stretched.

[0065] When the air cylinder unit 222 is extended to the limit position, the air pressure in the buffer air tank 218 gradually rises, and when it reaches the relief pressure of the continuous relief valve 220, the positive pressure gas input into the buffer air tank 218 by the extrusion air pump 217 is continuously discharged through the continuous relief valve 220, so that the gas pressure in the buffer air tank 218 is maintained within the corresponding range, thereby enabling the air cylinder unit 222 to remain in the extended state and continuously open the cross-slot 201.

[0066] When the humidity sensor detects that the humidity of the air to be dehumidified is low, the present application enters a low-power consumption state, in which the cross-slot 201 is continuously opened, and the first window 203 and the second window 204 are alternately opened. For specific principle analysis, please refer to Figure 4 When the first window 203 is opened and the second window 204 is closed, air enters the inside of the runner ring cover 2 through the first window 203, and then enters between the first runner 3 and the second runner 4 through the cross-slot 201, so that most of the air to be dehumidified bypasses the second runner 4 and is dehumidified only by the first runner 3, thereby greatly reducing air resistance and device power consumption. At this time, only a small amount of air to be dehumidified passes through the second runner 4, so that the second runner 4 can be slightly humidified and deeply dehumidified and regenerated during the rotation and regeneration process. When the first window 203 is closed and the second window 204 is opened, air is dehumidified by the second runner 4, and then enters the runner ring cover 2 through the cross-slot 201, and finally is directly discharged through the second window 204. Similarly, most of the air to be dehumidified bypasses the first runner 3, maintaining a low air resistance state. At this time, the first runner 3 can be deeply dehumidified and regenerated.

[0067] When the humidity of the air to be dehumidified increases beyond the set threshold value, the present application only needs to control the exhaust valve 221 to be opened and control the driving pinion 215 to be stopped.

[0068] When the exhaust valve 221 is opened, the positive pressure in the buffer air tank 218 is rapidly and completely discharged, and the air cylinder unit 222 loses air pressure support and is retracted under the elastic tension of the tension spring 223. At this time, the quick closing ring 202 quickly moves to the right side to close the cross-slot 201.

[0069] After the cross-slot 201 is closed, since at least one of the first window 203 and the second window 204 remains closed, the air to be dehumidified can only pass through the second runner 4 and the first runner 3 at the same time to complete efficient and uniform dehumidification.

[0070] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
