Description

Technical Field

[0001] The utility model belongs to the technical field of tile quality inspection, and particularly relates to a heat recovery tile immersion device. Background Art

[0002] After the ceramic tile is fired and cooled, the residual internal stress is slowly released, and local warping and other undesirable phenomena will occur within a few days after firing, affecting the flatness of the ceramic tile. This is the phenomenon of flipping. Since large-sized ceramic tiles have obvious flipping, large-sized ceramic tiles after firing and cooling need to undergo "flipping" testing and other quality inspection methods before they can be packaged and sold.

[0003] In order to speed up the release of residual internal stress in tiles, manufacturers generally soak them in hot water for several hours instead of leaving them for several days to save time. However, existing tile soaking equipment generally generates hot water through heating methods such as electricity and gas, which consumes a lot of energy. After firing the tiles, the kiln needs to be slowly cooled, which easily leads to waste of heat energy in the kiln. Utility Model Content

[0004] The utility model aims to provide a heat recovery brick immersion device to solve the technical problems that the existing brick immersion equipment has high heating energy consumption and cannot recover kiln heat energy.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] The utility model discloses a heat recovery brick soaking device, comprising a box body and a cover body connected to each other, wherein a soaking pool with an upward opening is arranged in the box body, and the soaking pool is provided with:

[0007] A limiting member, wherein a plurality of the limiting members are provided and are evenly laid along a first direction, the limiting members are connected to the pool wall of the soaking pool along an up-down direction and a second direction, and two adjacent limiting members are formed with limiting grooves for clamping tiles, wherein the second direction is a horizontal direction perpendicular to the first direction;

[0008] A heating mechanism includes a first heating component arranged around the soaking pool.

[0009] The heat exchange tube is passed through the limiting member, and the opposite ends of the heat exchange tube pass through the box body and are connected with an air inlet and an air outlet for connecting to the kiln, and the air inlet or the air outlet is connected to an air pump.

[0010] The present invention has at least the following beneficial effects: liquid for soaking tiles is transported to the soaking pool in advance, and the high-temperature kiln flue gas generated after the kiln combustion can be transported to the heat exchange tube through the air pump and the air inlet. Since the heat exchange tube is passed through the limiter, and the limiter is located in the soaking pool, the high-temperature kiln flue gas and the liquid in the soaking pool can exchange heat through the tube wall of the heat exchange tube, so that the liquid in the soaking pool is heated by the kiln heat energy, the kiln heat energy is recovered and applied to the hot soaking process of the tiles, and the energy consumption of the first heating component for heating the liquid in the soaking pool is reduced.

[0011] The plurality of stoppers form a plurality of stop grooves for clamping tiles, so as to prevent the tiles from deflecting or swinging in the soaking pool, thereby affecting the number of tiles that can be placed in the soaking pool. The cover body is connected to the box body to prevent the heated liquid from losing too much heat through the upper opening of the soaking pool.

[0012] As a further improvement of the above technical solution, a cavity is formed between the outer wall surface of the box body and the wall surface of the soaking pool, and a heat-insulating medium is provided in the cavity.

[0013] Through the above arrangement, the heat insulation function between the outer wall of the box body and the wall of the soaking pool is improved, thereby preventing the heated liquid from radiating heat through the wall of the soaking pool.

[0014] As a further improvement of the above technical solution, the heat exchange tube is provided with a plurality of first U-shaped coils which are connected in sequence and laid at intervals along the up and down directions, each of the first U-shaped coils includes a plurality of first straight tubes which are laid at intervals along the first direction and extend along the second direction, and the opposite ends of the first straight tubes are both inserted into the limit piece and the cavity, and are respectively connected with the two adjacent first straight tubes in the cavity.

[0015] Through the above arrangement, the kiln smoke enters the first U-shaped coil through the air inlet, and flows in sequence through the multiple connected first straight pipes that constitute the first U-shaped coil, and then flows through the multiple first U-shaped coils that are connected up and down, first horizontally heating the liquid in the immersion pool, and then moving to another height of the immersion pool to horizontally heat the liquid again.

[0016] As a further improvement of the above technical solution, the heat exchange tube includes an air intake main pipe, a plurality of second U-shaped coils and an air outlet main pipe, the air intake main pipe and the air outlet main pipe are respectively connected to the air intake port and the air outlet port, and the opposite ends of all the second U-shaped coils are respectively connected to the air intake main pipe and the air outlet main pipe;

[0017] The second U-shaped coil is laid in the limiting member, and includes a plurality of second straight pipes laid at intervals in the up-down direction and extending in the second direction, and two adjacent second straight pipes are connected in the up-down direction.

[0018] Through the above arrangement, the kiln flue gas enters the air inlet main pipe through the air inlet, and is diverted to multiple second U-shaped coils through the air inlet main pipe. The kiln flue gas diverted to the multiple second U-shaped coils converges in the air outlet main pipe and then flows out through the air outlet. The heat exchange efficiency and heat exchange effect of the kiln flue gas and the immersion pool liquid are improved by the multiple diverted second U-shaped coils.

[0019] As a further improvement of the above technical solution, the air inlet is lower than the air outlet.

[0020] Through the above arrangement, the high-temperature kiln flue gas enters from the bottom and exits from the top. The temperature of the lower layer of liquid after heat exchange is higher. The hotter liquid will automatically flow upward due to the reduction in density, thereby exchanging heat with the upper layer of liquid in the immersion tank, increasing the heat exchange effect between the liquids and improving the heat exchange efficiency.

[0021] As a further improvement of the above technical solution, the heating mechanism also includes a second heating component, and the second heating component is laid in the limiting member and is staggered with the heat exchange tube.

[0022] Through the above-mentioned arrangement, the second heating component is passed through and laid in the limiting member to improve the heating efficiency of the second heating component on the liquid in the immersion pool, and to avoid the first heating component arranged around the wall of the immersion pool only heating the liquid at the edge of the immersion pool, resulting in the liquid in the middle of the immersion pool between the tiles taking a longer time to achieve the heating effect.

[0023] As a further improvement of the above technical solution, a buffer member parallel to the limiting member is provided in the limiting groove.

[0024] Through the above arrangement, the buffer member is used to buffer the impact force between the tiles and the limiting groove when the tiles are placed in or taken out of the limiting groove, thereby avoiding damage to the tiles.

[0025] As a further improvement of the above technical solution, a brick-holding member for placing tiles is provided in the limiting groove, and the brick-holding member is connected with a hanging ring.

[0026] Through the above arrangement, the tiles can be placed in the tile support in advance, and the lifting ring can be hooked by the cantilever crane to drive the tile support to be taken and placed in the limiting groove, so as to prevent the tiles and the limiting part from being bumped.

[0027] As a further improvement of the above technical solution, the heat recovery brick immersion device also includes a controller, and two temperature sensors are laid in the immersion pool along the up and down directions. The controller is electrically connected to the heating mechanism, the air pump and the two temperature sensors.

[0028] Through the above settings, the controller can control the opening and closing of the air pump and the heating mechanism. When the air pump is turned on and the detection temperatures of the two temperature sensors can reach the heating temperature required for the tiles, there is no need to turn on the heating mechanism, which saves energy consumption, and the liquid temperature in the soaking pool can always meet the soaking temperature of the tiles by controlling the opening and closing of the air pump. When the air pump is in the on state and the detection temperature of the temperature sensor cannot meet the soaking temperature of the tiles within the duration, the controller can turn on the heating mechanism to raise the liquid temperature in the soaking pool to the soaking temperature of the tiles.

[0029] As a further improvement of the above technical solution, the heat recovery brick immersion device also includes a water tank, a water pump and a liquid level sensor. The controller is electrically connected to the water pump and the liquid level sensor. The water tank and the immersion pool are connected by a drain port. The water pump is connected by a water pipe connected to the bottom of the water tank and the immersion pool. The liquid level sensor is arranged at the top of the immersion pool and is higher than the limit member.

[0030] Through the above settings, when the liquid level is insufficient, the liquid level sensor cannot detect the liquid level information, and the controller starts the water pump to replenish the immersion pool, and the liquid in the water tank is transported to the immersion pool through the water pipe until the liquid level sensor detects the liquid level information. At this time, the tile can be completely immersed in the liquid in the immersion pool. When the volume of the liquid in the immersion pool is too large, when the tile is placed in the limit groove, the overflowing liquid can be discharged to the water tank through the drain port, and the excess liquid in the immersion pool is recovered to prevent the liquid from overflowing from the edge of the box.

[0047] It should be noted that in the accompanying drawings, the X direction is from the right side of the heat recovery brick immersion device to the left side; the Y direction is from the front side of the heat recovery brick immersion device to the rear side; and the Z direction is from the bottom side of the heat recovery brick immersion device to the top side.

[0048] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0049] Reference Figures 1 to 3 , several embodiments of the heat recovery brick immersion device of the present invention are given below.

[0050] like Figures 1 to 3 As shown, the heat recovery brick immersion device of the embodiment of the utility model includes a box body 100, and a soaking pool 110 with an upward opening is provided in the box body 100. The soaking pool 110 can be loaded with hot water. The ceramic tile 800 can be moved from top to bottom into the soaking pool 110 and soaked in hot water, so as to achieve soaking in hot water instead of placing it for several days, accelerate the release of the residual internal stress of the ceramic tile 800, and facilitate the detection of whether the large-sized ceramic tile 800 will have local warping and other undesirable phenomena, thereby improving the quality inspection efficiency.

[0051] In this embodiment, the box 100 is a cubic structure extending along a first direction, a second direction and an up-down direction, and the first direction and the second direction are perpendicular to each other and are both horizontal directions. The soaking pool 110 is a cubic cavity.

[0052] It is understandable that the upper end of the box 100 is connected to a cover 700, and the cover 700 can completely cover the soaking pool 110 to prevent the hot water in the box 100 from dissipating heat through the opening of the soaking pool 110. Figure 1 and Figure 3 shown.

[0053] It is understandable that the cover 700 and the box body 100 can be connected by closing, hinged, etc. In this embodiment, the cover 700 is connected with a lifting ear 710, such as Figure 1 and Figure 3 As shown, the cover 700 can be rotated and switched on the box body 100 by hooking a lifting ear 710 with a cantilever crane.

[0054] It is understandable that a plurality of stoppers 200 are provided in the soaking pool 110, such as Figures 1 to 3 As shown, the limiting member 200 is used to limit the movement of the tile 800 in the soaking tank 110 to prevent the tile 800 from tilting and reducing the amount of tiles 800 that can be placed in the soaking tank 110.

[0055] In this embodiment, a plurality of limit members 200 are laid at intervals along a first direction so that a plurality of tiles 800 can be laid in the soaking pool 110 along the first direction. The intervals between every two adjacent limit members 200 are the same so that the number of tiles 800 clamped between two adjacent limit members 200 is the same, which facilitates uniform heating of the tiles 800. The limit members 200 are connected to the pool wall of the soaking pool 110 along the up-down direction and the second direction. When projected in the first direction, the limit members 200 are shaped like a U-shaped structure with an opening facing upward, and the outer side surface of the limit members 200 is connected to the pool wall of the soaking pool 110. A limit groove 210 is formed between two adjacent limit members 200, such as Figure 1 and Figure 2 As shown, when the tile 800 is clamped in the limit groove 210 from top to bottom by a cantilever crane, the two end edges and the lower edge of the tile 800 along the second direction are abutted by two adjacent limit members 200, so that the tile 800 is clamped in the limit groove 210 in a vertical direction, which is convenient for vertically lifting it again by the cantilever crane after the soaking is completed, so as to facilitate the replacement of new tiles 800 that need to be soaked in hot water.

[0056] It is understandable that the width of the limiting groove 210 along the first direction can be set according to the number of pre-placed tiles 800 and the thickness of the tiles 800.

[0057] In this embodiment, the first direction is the left-right direction, and the second direction is the front-back direction.

[0058] It is understandable that a heating mechanism is also provided in the soaking pool 110, and the heating mechanism includes a first heating component 310, and the first heating component 310 is laid around the wall of the soaking pool 110 to heat the liquid in the soaking pool 110. Figure 1 shown.

[0059] It is understandable that the immersion pool 110 is further provided with a heat exchange tube 400 passing through the stopper 200, and the heat exchange tube 400 is immersed in the liquid of the immersion pool 110. Figure 1 and Figure 2 The opposite ends of the heat exchange tube 400 pass through the box body 100 and are connected to an air inlet 510 and an air outlet 520. The air inlet 510 or the air outlet 520 is connected to an air pump 530. Figure 2 As shown, the air inlet 510 and the air outlet 520 are both connected to the kiln.

[0060] With such an arrangement, when the kiln is cooled after combustion, the air pump 530 can be started to guide the high-temperature flue gas generated by the combustion of the kiln into the heat exchange tube 400 through the air inlet 510, and heat exchange occurs with the liquid in the immersion tank 110 through the tube wall of the heat exchange tube 400, so as to heat the liquid with the heat energy generated by the combustion of the kiln, thereby reducing the heating power and energy consumption of the heating mechanism.

[0061] Since the gas outlet 520 is connected to the kiln, the flue gas temperature after heat exchange is relatively low, and can be discharged to the kiln through the gas outlet 520 to reduce the temperature of the kiln and speed up the cooling of the kiln. Moreover, the circulated flue gas eventually returns to the kiln and can be processed by the flue gas treatment device connected to the kiln to prevent the kiln flue gas from polluting the environment.

[0062] In this embodiment, a cavity 120 is formed between the outer wall surface of the box 100 and the wall surface of the soaking pool 110, and a heat preservation medium 130 is provided in the cavity 120. Figure 1 and Figure 2 As shown, the liquid in the immersion tank 110 is kept warm, the possibility of heat exchange between the liquid and the box 100 is reduced, and the heat loss of the liquid is reduced.

[0063] It is understandable that the thermal insulation medium 130 may be rock wool, glass wool or polyurethane, etc.

[0064] Furthermore, a heat preservation medium 130 is also provided in the cover body 700 to further preserve heat and reduce heat loss.

[0065] In some embodiments, the heat exchange tube 400 is a whole pipe. Specifically, the heat exchange tube 400 includes a plurality of first U-shaped coils 410 laid at intervals in the vertical direction, and two adjacent first U-shaped coils 410 are connected to each other. Figure 2 shown.

[0066] It can be understood that the first U-shaped coil 410 located at the top is connected to one of the air inlet 510 and the air outlet 520, and the first U-shaped coil 410 located at the bottom is connected to the other of the air inlet 510 and the air outlet 520, so that the high-temperature kiln flue gas can pass through each first U-shaped coil 410 from bottom to top or from top to bottom in sequence, ensuring the heat exchange effect between the liquid in the immersion tank 110 and the kiln flue gas.

[0067] In this embodiment, the first U-shaped coil 410 at the bottom is connected to the outside of the box 100 with an air inlet 510, and the first U-shaped coil 410 at the top is connected to the outside of the box 100 with an air outlet 520. Figure 2 As shown, the kiln flue gas introduced into the heat exchange tube 400 flows from bottom to top. The temperature of the lower layer of liquid after heat exchange is higher, and the hotter liquid will automatically flow upward due to the reduction in density, thereby exchanging heat with the upper layer of liquid in the immersion tank 110, increasing the heat exchange effect between the liquids and improving the heat exchange efficiency.

[0068] It can be understood that each first U-shaped coil 410 includes a plurality of first straight tubes 411, and the plurality of first straight tubes 411 are arranged at intervals along the first direction on the left and right and are evenly laid in a plurality of stoppers 200 arranged on the left and right. Figure 2The first straight tube 411 extends along the second front-to-back direction, and the front and rear ends of the first straight tube 411 pass through the corresponding stopper 200 and the wall of the soaking pool 110 along the front-to-back direction, and the front and rear ends of the first straight tube 411 are both mounted in the cavity 120.

[0069] It can be understood that the front end of the first straight tube 411 is connected to the front end of one of the first straight tubes 411 adjacent to the left and right, and the rear end of the first straight tube 411 is connected to the rear end of another first straight tube 411 adjacent to the left and right, so that all the first straight tubes 411 in each first U-shaped coil 410 are connected in series in sequence along the left and right directions, and the kiln smoke can flow along each first U-shaped coil 410.

[0070] It can be understood that the air inlet and air outlet of each first U-shaped coil 410 are respectively arranged at the two first straight pipes 411 at the edge along the first direction. The air inlet and air outlet of two adjacent first U-shaped coils 410 are staggered in the vertical direction, that is, the air outlet of the first U-shaped coil 410 and the air inlet of the adjacent upper first U-shaped coil 410 are opposite to each other and connected to each other, so that the two adjacent first U-shaped coils 410 are connected to each other, so that the kiln smoke can flow upward from the air inlet 510 to each first U-shaped coil 410 in sequence.

[0071] It can be understood that two adjacent first straight tubes 411 are connected by arcs, so that the kiln smoke can flow through all the first straight tubes 411 in sequence, thereby reducing tube loss.

[0072] In other embodiments, the heat exchange tube 400 is a plurality of pipes connected in parallel. Specifically, the heat exchange tube 400 includes an air intake manifold 420, an air outlet manifold 440, and a plurality of second U-shaped coils 430. The air intake manifold 420 is connected to the air intake port 510, and the air outlet manifold 440 is connected to the air outlet port 520. The plurality of second U-shaped coils 430 are arranged in parallel, and the opposite ends of each second U-shaped coil 430 are respectively connected to the air intake manifold 420 and the air outlet manifold 440. The second U-shaped coils 430 are laid in the stopper 200, as shown in FIG. Figure 3 shown.

[0073] With such arrangement, the high-temperature kiln flue gas is input into the air intake main pipe 420 through the air inlet 510. Since the plurality of second U-shaped coils 430 are connected to the air intake main pipe 420, the kiln flue gas flows evenly to each second U-shaped coil 430. Since the second U-shaped coil 430 is laid in the stopper 200, the kiln flue gas flowing in the second U-shaped coil 430 can evenly exchange heat with the liquid in the soaking tank 110, thereby improving the heat conversion efficiency of the two. The other end of the second U-shaped coil 430 is connected to the air outlet main pipe 440, and the kiln flue gas passing through the second U-shaped coil 430 is collected in the air outlet main pipe 440 and discharged back into the kiln through the air outlet 520 connected to the air outlet main pipe 440.

[0074] It can be understood that each second U-shaped coil 430 includes a plurality of second straight tubes 431, and the plurality of second straight tubes 431 are arranged at intervals in the vertical direction and evenly laid in the stopper 200, such as Figure 3 As shown, the upper and lower spacings of each second straight tube 431 are the same.

[0075] It can be understood that the second straight pipe 431 extends in the second direction of front and back, the front end of the second straight pipe 431 is connected to the front semicircle of one of the second straight pipes 431 adjacent to each other, and the rear end of the second straight pipe 431 is connected to the rear end of another second straight pipe 431 adjacent to each other, so that all the second straight pipes 431 in each second U-shaped coil 430 are connected in series in sequence in the up-down direction, and the kiln smoke can flow through the second U-shaped coil 430, such as Figure 3 shown.

[0076] It is understandable that, since a plurality of stoppers 200 are arranged in the left-right direction, a plurality of second U-shaped coils 430 are also arranged in sequence in the left-right direction. The number of second U-shaped coils 430 may correspond to the stoppers 200 one by one, so that each stopper 200 is provided with a second U-shaped coil 430, thereby increasing the contact area between the kiln flue gas and the liquid in the soaking pool 110 and improving the heat exchange effect. Two adjacent second U-shaped coils 430 may also be spaced apart by one or more stoppers 200 to reduce the number of second U-shaped coils 430 to be laid, making the soaking pool 110 more concise.

[0077] It can be understood that the air intake manifold 420 and the air outlet manifold 440 extend along the first direction and are laid in the cavity 120, the air intake manifold 420 is located at the lower end of the cavity 120, and the air outlet manifold 440 is located at the upper end of the cavity 120. Figure 3 As shown, the high-temperature kiln smoke enters from the bottom and exits from the top. The second straight pipe 431 at the bottom of each second U-shaped coil 430 passes through the stopper 200 and communicates with the air inlet manifold 420 in the cavity 120; the second straight pipe 431 at the top of each second U-shaped coil 430 passes through the stopper 200 and communicates with the air outlet manifold 440 in the cavity 120.

[0078] It can be understood that when the tile 800 is stuck in the limiting groove 210, if the heat exchange tube 400 includes a first straight tube 411, all the first straight tubes 411 are located on the left or right side of the tile 800; if the heat exchange tube 400 includes a second straight tube 431, all the second straight tubes 431 are located on the left or right side of the tile 800. The first straight tube 411 and the second straight tube 431 neither affect the tile 800 entering and exiting the immersion pool 110, but can also heat the liquid near the tile 800 to prevent the liquid temperature between the tiles 800 from being insufficient to accelerate the release of residual internal stress of the tile 800.

[0079] It can be understood that the air inlet 510 is lower than the air outlet 520 so that the high-temperature kiln smoke can enter from the bottom and exit from the top.

[0080] It is understandable that the heating mechanism further includes a second heating component 320, and the second heating component 320 is laid in the limiting member 200, such as Figure 3 As shown, the liquid between the tiles 800 is heated to improve the heating effect and heating efficiency of the heating mechanism on the liquid in the pool, so as to avoid the first heating component 310 arranged around the wall of the immersion pool 110 only being able to increase the liquid temperature at the edge of the tile 800 in a short time.

[0081] It can be understood that in the direction of left-right projection, the second heating assembly 320 and the heat exchange tube 400 are arranged in an up-and-down staggered manner, such as Figure 3 As shown. Specifically, the second heating assembly 320 includes a plurality of heating tube assemblies laid at intervals along the left-right direction, each heating tube assembly is evenly laid in the stopper 200, and each heating tube assembly includes a plurality of heating tubes connected in sequence. If a first straight tube 411 or a second straight tube 431 is provided in each stopper 200, the heating tube and the first straight tube 411 or the second straight tube 431 are staggered in the up-down direction. If a plurality of first straight tubes 411 or a plurality of second straight tubes 431 in the left-right direction are spaced apart by a stopper 200, the heating tube and the first straight tube 411 or the second straight tube 431 can also be staggered in the left-right direction.

[0082] In this embodiment, the first heating component 310 and the second heating component 320 are both electric heating tubes, which can heat the liquid in the immersion tank 110 after being powered on.

[0083] It is understandable that the jib crane can directly clamp the tile 800 in the limiting groove 210 through the clamping device. However, since the groove wall of the limiting groove 210 is the pool wall surface of the soaking pool 110, the tile 800 is easy to collide with the pool wall surface of the soaking pool 110, resulting in damage or breakage of the tile 800.

[0084] In some embodiments, a buffer member 220 is disposed in the limiting groove 210. Figure 1 and Figure 2 As shown, the buffer member 220 is parallel to the limiting member 200, so that the buffer member 220 is laid along the wall of the soaking pool 110, buffering the force when the tile 800 is placed in the limiting groove 210, thereby avoiding damage to the tile 800.

[0085] Furthermore, the buffer member 220 may be extended and laid along the limiting members 200 on the left and right sides to prevent the tile 800 from colliding with the limiting members 200 on the left and right sides when being placed in the limiting groove 210 .

[0086] In other embodiments, a brick support is further provided in the soaking pool 110. The ceramic tile 800 is placed in the brick support in advance after cooling. The brick support is connected with a lifting ring. The cantilever crane can hook the connecting lifting ring and drive the brick support to move up and down into the limiting groove 210. The brick support is a frame structure, which is used to protect the ceramic tile 800 and prevent the ceramic tile 800 from being bumped.

[0087] It is understandable that the lifting ring and the brick-bearing member can be connected in a hinged manner to facilitate stacking of multiple brick-bearing members up and down to save placement space. The cantilever crane can hook and lift the brick-bearing members in the immersion tank 110 from top to bottom in sequence.

[0088] Furthermore, the edge of the limiting member 200 facing the limiting groove 210 is rounded to prevent the limiting member 200 from scratching the surface of the tile 800, and to facilitate guiding the clamped tile 800 or the hooked tile supporting member to be clamped in the limiting groove 210.

[0089] It is understandable that the box 100 is also provided with an electrically connected controller and two temperature sensors 330, the two temperature sensors 330 are laid out in the vertical direction at intervals and are respectively installed at the upper and lower ends of the soaking tank 110, such as Figure 1 As shown, the upper layer liquid temperature and the lower layer liquid temperature of the soaking tank 110 are respectively used to detect the upper layer liquid temperature and the lower layer liquid temperature of the soaking tank 110, and transmit the temperature signal to the controller.

[0090] It is understandable that the controller is electrically connected to the air pump 530. The staff can set the heating temperature and the set temperature of the liquid through the controller. When the detection temperature of any temperature sensor 330 is lower than the heating temperature, the staff can turn on the air pump 530 through the controller to allow the high-temperature kiln flue gas to enter the heat exchange tube 400 to achieve heat exchange and increase the temperature of the liquid in the soaking tank 110. When the detection temperatures of the two temperature sensors 330 are both higher than the set temperature, the air pump 530 can be turned off through the controller to ensure that the temperature of the liquid in the soaking tank 110 is always maintained between the heating temperature and the set temperature, meeting the temperature requirement for the ceramic tile 800 to quickly release the internal stress.

[0091] Further, the controller is electrically connected to the heating mechanism. When the controller turns on the air pump 530 and the temperature sensor 330 still cannot detect the increase in the liquid temperature of the immersion tank 110 or the increased liquid temperature cannot be higher than the heating temperature, the controller can turn on the heating mechanism to increase the liquid temperature.

[0092] It is understandable that the liquid volume of the soaking pool 110 is fixed. When each limiting groove 210 in the soaking pool 110 is placed with a tile 800, the liquid level in the soaking pool 110 rises and is higher than the top of the tile 800, so that the tile 800 can be completely immersed in hot water. However, when the number of tiles 800 placed in the soaking pool 110 is small, the liquid volume in the soaking pool 110 is insufficient, and the liquid level cannot be higher than the top of the tile 800, so the tile 800 is easily damaged by uneven heating.

[0093] In this regard, the heat recovery brick immersion device also includes a water storage mechanism, which includes a water storage tank 600, a water pump 610 and a liquid sensor, such as Figure 1 Specifically, the water pump 610 and the liquid level sensor 620 are both electrically connected to the controller. The liquid level sensor 620 is used to detect the liquid level in the soaking tank 110 and transmit the liquid level information to the controller. The upper end of the water storage tank 600 and the upper end of the soaking tank 110 are connected to each other, and a drain port 630 is provided at the connection point. The drain port 630 is lower than the upper end surface of the soaking tank 110, as shown in FIG. Figure 1 The water pump 610 is connected to a water pipe 611, the water inlet end of the water pipe 611 is located at the bottom of the water storage tank 600, and the water outlet end of the water pipe 611 is located at the soaking pool 110, as shown. Figure 1 The liquid level sensor 620 is disposed at the upper portion of the soaking tank 110, and when the tile 800 is stuck in the limiting groove 210, the liquid level sensor 620 is higher than the top of the tile 800, as shown in FIG. Figure 1 shown.

[0094] With such arrangement, when the tiles 800 are placed in the limiting grooves 210 in sequence, if the liquid level in the immersion pool 110 rises and is higher than the drain port 630, the excess liquid will flow to the water tank 600 through the drain port 630 to prevent the liquid from overflowing the immersion pool 110. At this time, the liquid level is higher than the liquid level sensor 620, and the liquid level sensor 620 detects the liquid level information and transmits it to the controller.

[0095] When the tile 800 is placed in the limiting groove 210, when the liquid level in the immersion tank 110 rises but is lower than the liquid level sensor 620, the liquid level sensor 620 cannot detect the liquid level information, and the controller cannot receive the liquid level information sent by the liquid level sensor 620. At this time, the controller controls the water pump 610 to start and pump the liquid in the water tank 600 into the immersion tank 110 until the liquid level sensor 620 detects the liquid level information and transmits it to the controller. The controller controls the water pump 610 to shut down to ensure that the tile 800 is completely immersed in the liquid.
