Description

Technical Field

[0001] The utility model belongs to the technical field of the air-cooling structure of the green body, and particularly relates to a device and a kiln for efficiently adjusting the temperature difference in the cooling zone of the kiln. Background Art

[0002] Ceramics are sintered at high temperature. After entering the kiln, they go from low temperature to high temperature, pass through the smoke exhaust area, preheating area, and firing area for sintering or ceramization, and then cool down. After passing through the rapid cooling area, slow cooling area, and tail cooling area, they come out of the kiln to form ceramic products.

[0003] During the firing or cooling process, when there is a large temperature difference in the kiln, defects such as color difference, deformation, or cracking will occur in the products, resulting in a decrease in the qualified rate. Especially at present, the specifications of the green body are getting larger and larger (such as 1000mm*2000mm, 1200mm*2400mm, 1600mm*3200mm, etc.), and the firing cycle is getting shorter and shorter, and the requirements for the temperature difference are getting higher and higher. In the rapid cooling area, there is a liquid phase in the green body, and it can be quickly cooled. For example, for rock slabs, from the highest firing temperature of 1250°C to about 600°C, the green body shrinks sharply, and various deformations are likely to occur when the temperature difference is large. It is one of the key areas for adjusting the brick shape.

[0004] At present, most roller kilns are provided with multiple blowing branch pipes in the upper and lower directions of the roller rods for transporting the green body. Air enters from both sides of the air duct and blows towards the brick surface to cool the green body. The size of the air volume is adjusted by the valves provided outside each pipe or each group of pipes. The temperature difference of the cross-section is mainly adjusted by the valves. However, the temperature difference of the kiln needs to be adjusted according to the actual situation of the brick shape, otherwise problems such as uneven brick blanks, large deformation, and low qualified rate are likely to occur. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device and a kiln for efficiently adjusting the temperature difference in the cooling zone of the kiln, so as to solve the technical problems in the prior art that the temperature difference of the kiln is not easy to be accurately adjusted, the brick blanks are uneven, the deformation is large, and the qualified rate is low.

[0006] The technical solution adopted to solve the above technical problems:

[0007] The utility model discloses a device for efficiently adjusting the temperature difference in the cooling zone of the kiln, which includes multiple rapid cooling branch pipes arranged above and below the roller bricks. The multiple rapid cooling branch pipes located above and below are respectively arranged at intervals along the length direction of the kiln. The kiln walls on both sides of the kiln are respectively provided with adjustment holes. The two ends of the rapid cooling branch pipes respectively penetrate into the adjustment holes on both sides of the kiln wall. The adjustment holes extend along the up and down direction. The rapid cooling branch pipes are slidably connected to the adjustment holes, and a filling member is arranged in the adjustment holes.

[0008] The utility model has at least the following beneficial effects: the adjustment hole is located on the kiln wall, the adjustment hole extends in the up-down direction and the quenching branch pipe runs through the adjustment hole, so that the relative distance between the quenching branch pipe and the brick blank is adjusted by moving the quenching branch pipe in the up-down direction. When the relative distance between the quenching branch pipe and the brick blank increases, the temperature of the wind reaching the surface of the brick blank is high, the temperature difference between the wind temperature and the surface of the brick blank is small, the local cooling of the brick blank is moderated, and the shrinkage of the brick blank is reduced. When the relative distance between the quenching branch pipe and the brick blank decreases, the temperature of the wind reaching the surface of the brick blank is low, the temperature difference between the wind temperature and the surface of the brick blank increases, the local cooling of the brick blank is rapid, and the shrinkage of the brick blank is increased.

[0009] The distance between the quenching branch pipe and the bricks is adjusted according to the cooling requirements of different types of products and outputs to achieve different cooling effects, reduce the deformation of the bricks, and improve flatness and qualified rate.

[0010] The filling piece is inserted into the adjusting hole, specifically into the gap between the quenching branch pipe and the adjusting hole. The filling piece is pressed and sealed to prevent the heat of the kiln from escaping through the adjusting hole, thereby deteriorating the operating environment and increasing the energy consumption of the kiln.

[0011] As a further improvement of the above technical solution, an adjusting rod is passed through the quench branch pipe, and both ends of the adjusting rod are respectively connected to an adjusting valve plate and an adjusting handle, the adjusting valve plate is located inside the quench branch pipe, and the adjusting handle is located outside the quench branch pipe.

[0012] Through the above arrangement, the adjusting handle moves the adjusting valve plate to a position in the quenching branch pipe, thereby changing the output air volume and output position of the quenching branch pipe, correcting the brick shape of the brick blank, reducing the deformation of the brick blank, and improving the product quality of the brick blank.

[0013] As a further improvement of the above technical solution, both ends of the quenching branch pipe are respectively provided with sleeves connected to the air inlet duct, and the quenching branch pipe and the sleeves are locked and connected by fasteners.

[0014] Through the above arrangement, the cold air output from the air inlet duct is transported to the quenching branch pipe through the sleeve, and the fastener is used to lock the quenching branch pipe and the sleeve connected by the sleeve to prevent the cold air from leaking from the gap between the two.

[0015] As a further improvement of the above technical solution, an end of the sleeve away from the quench branch pipe is provided with an opening for the adjustment rod to pass through, the adjustment rod is threadedly connected to the opening, and the adjustment handle is located outside the sleeve.

[0016] Through the above arrangement, the adjusting handle is rotated to rotate the adjusting rod relative to the open thread, thereby changing the position of the adjusting valve plate relative to the quenching branch pipe. When there is no external force, the adjusting valve plate is fixed relative to the quenching branch pipe to prevent the wind pressure in the quenching branch pipe from forcing the adjusting valve plate to move.

[0017] As a further improvement of the above technical solution, connecting plates are horizontally connected to both sides of the kiln wall respectively. The connecting plate is provided with a connection hole opposite to the quenching branch pipe up and down, and a locking member for connecting the quenching branch pipe is inserted into the connection hole.

[0018] Through the above setting, the locking member is connected to the quenching branch pipe. When the locking member is fixed relative to the connecting plate, the quenching branch pipe and the kiln are relatively fixed, avoiding affecting the relative position between the quenching branch pipe and the adjustment hole when the filling member is filled.

[0019] As a further improvement of the above technical solution, the locking member includes an adjusting bolt and a locking nut connected by threads.

[0020] Through the above setting, the position adjustment and fixation of the quenching branch pipe and the kiln are realized through the threaded connection of the adjusting bolt and the locking nut.

[0021] As a further improvement of the above technical solution, the outer end surface of the quenching branch pipe is rotatably connected to the locking nut. The connection hole is an internal threaded hole, and one end of the adjusting bolt is threadedly inserted through the connection hole and threadedly connected to the locking nut.

[0022] Through the above setting, the adjusting bolt and the locking nut are relatively fixed by threaded connection. By screwing the adjusting bolt, the relative position between the adjusting bolt and the connecting plate is adjusted, thereby adjusting the relative position between the quenching branch pipe and the kiln.

[0023] As a further improvement of the above technical solution, the connecting plate is connected with a fixing plate extending up and down. The fixing plate is connected to the kiln wall. The fixing plate is provided with a plurality of installation holes, which correspond to the adjustment holes of the kiln wall one by one. The shapes and sizes of the installation holes are respectively the same as those of the adjustment holes.

[0024] Through the above setting, after the quenching branch pipe passes through the adjustment hole of the kiln wall and the installation hole of the fixing plate, it is fixed relative to the connecting plate through the adjusting bolt and the locking nut. The connecting plate is simply and quickly connected to the kiln wall through the fixing plate.

[0025] The utility model discloses a kiln, including the device for efficiently adjusting the temperature difference in the cooling zone of the kiln as described in any one of the above.

[0026] The utility model has at least the beneficial effect that: the kiln can adjust the air volume blown to the brick blank by adjusting the position of the quenching branch pipe in the adjustment hole, reduce the temperature difference of the cross section, and further solve the problems of large flatness, large deformation amount and low qualification rate of the brick blank.

[0027] As a further improvement of the above technical solution, it includes an air inlet pipe, a valve and a telescopic pipe. The air inlet pipe is communicated with a plurality of valves, and the opposite ends of the telescopic pipe are respectively communicated with the valve and the quenching branch pipe.

[0028] With the above settings, the cold air in the quench branch pipe is input through the connected air inlet pipe, air valve and telescopic pipe. The air valve can adjust the input air volume and further adjust the temperature difference of the cross-section. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Refer to Figures 1 to 3 , and several embodiments of the device and kiln furnace for efficiently adjusting the temperature difference in the cooling zone of the present utility model are given below.

[0049] As Figures 1 to 3 shown, a device for efficiently adjusting the temperature difference in the cooling zone of an embodiment of the present utility model includes a plurality of rapid cooling branch pipes 200. The plurality of rapid cooling branch pipes 200 are respectively located above and below the roller fired bricks. The plurality of rapid cooling branch pipes 200 located above are laid at intervals along the length direction of the kiln furnace 100, and the plurality of rapid cooling branch pipes 200 located below are also laid at intervals along the length direction of the kiln furnace 100. The rapid cooling branch pipes 200 are provided with air outlet holes facing the bricks to blow the air for cooling onto the surface of the bricks for cooling.

[0050] It can be understood that both opposite sides of the kiln furnace 100 are kiln walls, and a plurality of adjustment holes 150 are provided on the kiln walls. As Figure 3 shown, the opposite ends of the rapid cooling branch pipes 200 are respectively inserted into the adjustment holes 150 on the kiln walls on both sides. The rapid cooling branch pipes 200 are stably installed in the kiln furnace 100 through the two adjustment holes 150 to stably convey cold air to the bricks.

[0051] It can be understood that the adjustment holes 150 are arranged to extend in the up and down direction. As Figure 3 shown, the opposite ends of the quench branch pipe 200 can be respectively slid within two adjustment holes 150 extending in the up and down direction, so as to adjust the height position of the quench branch pipe 200, that is, the distance between the air outlet hole and the brick blank.

[0052] With such an arrangement, since the air temperature output by the quench branch pipe 200 is lower than the temperature inside the kiln 100, when the quench branch pipe 200 moves away from the brick blank, the distance between the air outlet hole and the brick blank gradually becomes larger, and the time for the air blown out from the air outlet hole to be heated by the temperature inside the kiln is longer, then the temperature of the air reaching the surface of the brick blank is higher, the temperature difference between the air temperature blown out from the air outlet hole and the surface of the brick blank decreases, the local cooling of the brick blank is alleviated, and the shrinkage of the brick blank becomes smaller.

[0053] When the quench branch pipe 200 moves towards the brick blank, the distance between the air outlet hole and the brick blank gradually becomes smaller, and the time for the air blown out from the air outlet hole to be heated by the temperature inside the kiln is shorter, then the temperature of the air reaching the surface of the brick blank is lower, the temperature difference between the air temperature blown out from the air outlet hole and the surface of the brick blank increases, the local cooling of the brick blank is sharp, and the shrinkage of the brick blank becomes larger.

[0054] The quench branch pipe 200 that slides relative to the kiln 100 can achieve different cooling effects of different air temperatures on the brick blank, so as to adjust the corresponding cooling requirements according to different types of products and production volumes, improve the applicability of a device for efficiently adjusting the temperature difference in the cooling zone of the kiln, make the brick blank flat, reduce the deformation amount, and improve the qualification rate.

[0055] In this embodiment, a filling member 400 is provided in the adjustment hole 150, as Figure 2 shown. After the quench branch pipe 200 slides relative to the adjustment hole 150, the filling member 400 fills the gap between the outer end face of the quench branch pipe 200 and the hole wall surface of the adjustment hole 150, and is pressed and sealed to prevent the heat inside the kiln 100 from escaping through the adjustment hole 150, the temperature of the external environment of the kiln 100 from rising, and problems such as the energy consumption of the kiln 100.

[0056] It can be understood that the filling member 400 is loose cotton such as light refractory insulating cotton, high-aluminum fiber or rock wool. The loose cotton has the characteristics of light weight, high strength, oxidation resistance, etc., and is convenient to be filled in the adjustment hole 150 to seal, insulate and heat-insulate the kiln 100.

[0057] In this embodiment, the length direction of the kiln 100 is arranged along the front-rear direction. A plurality of upper quenching branch pipes 200 and a plurality of lower quenching branch pipes 200 are respectively laid at intervals along the front-rear direction, and the green bricks are conveyed along the front-rear direction. The air outlet holes on the upper quenching branch pipes 200 face downward to cool the upper surface of the green bricks, and the air outlet holes on the lower quenching branch pipes 200 face upward to cool the lower surface of the green bricks. Each quenching branch pipe 200 is provided with a plurality of air outlet holes arranged at intervals in the left-right direction.

[0058] In some embodiments, the lower quenching branch pipes 200 are located between two adjacent upper quenching branch pipes 200, so that a plurality of quenching branch pipes 200 are arranged in a staggered manner.

[0059] In this embodiment, the lower quenching branch pipes 200 and the upper quenching branch pipes 200 are symmetrically arranged up and down, as Figure 3 shown. When the green brick is at the midline of the upper quenching branch pipe 200 and the lower quenching branch pipe 200, the temperature differences on the upper brick surface and the lower brick surface are the same, reducing the flatness of the green brick.

[0060] It can be understood that the quenching branch pipes 200 extend in the left-right direction, the adjusting holes 150 are located on the left and right sides of the kiln 100, the adjusting holes 150 extend in the up-down direction, and the quenching branch pipes 200 can slide up and down relative to the kiln 100 to adjust the up-down distance between the air outlet holes and the green bricks.

[0061] It can be understood that a plurality of quenching branch pipes 200 are symmetrically arranged up and down, and each quenching branch pipe 200 corresponds to two left-right symmetric adjusting holes 150 respectively. There are also a plurality of adjusting holes 150 corresponding to the plurality of quenching branch pipes 200. The plurality of adjusting holes 150 located on the left side of the kiln 100 and the plurality of adjusting holes 150 located on the right side of the kiln 100 are symmetrically arranged. The plurality of adjusting holes 150 on each side of the kiln 100 are symmetrically arranged up and down, and the adjusting holes 150 located above are arranged at intervals in the front-rear direction.

[0062] It can be understood that the quenching branch pipe 200 is provided with an adjusting assembly. The adjusting assembly includes an adjusting rod 900, an adjusting valve plate 910 and an adjusting handle 920. The opposite ends of the adjusting rod 900 are respectively connected with the adjusting valve plate 910 and the adjusting handle 920. The adjusting valve plate 910 is located at the inner end of the quenching branch pipe 200, as Figure 1 shown. The adjusting handle 920 is located at the outer end of the quenching branch pipe 200, as Figure 2 shown. Specifically, the diameter of the adjusting valve plate 910 is slightly smaller than the inner pipe diameter of the quenching branch pipe 200. Therefore, when the adjusting handle 920 is pulled, the adjusting rod 900 drives the connected adjusting valve plate 910 to move left and right in the quenching branch pipe 200, thereby adjusting the output air volume and output position of the quenching branch pipe 200, facilitating the change of the brick shape of the green brick, reducing deformation, and improving the product quality of the green brick.

[0063] It is understandable that each quench branch pipe 200 is equipped with two adjustment components. The two adjustment rods 900 extend out from the left end and the right end of the quench branch pipe 200 respectively. The air outlet holes located between the two adjustment valve plates 910 do not output or output less cold air.

[0064] It is understandable that when the adjustment valve plate 910 moves towards the center of the kiln, that is, when the adjustment valve plate 910 moves towards the center of the quench branch pipe 200, the quench branch pipe 200 has more air outlet holes for outputting air volume, more air volume is output into the kiln furnace 100, and the cooling range and temperature drop amplitude are large; when the adjustment valve plate 910 moves towards the side of the kiln furnace 100, the quench branch pipe 200 has fewer air outlet holes for outputting air volume, the air volume output by the air outlet holes is small, the air outlet is concentrated on both sides of the kiln furnace 100, and the temperature drop range and amplitude are small, which is convenient for reducing the cross-sectional temperature difference in detail.

[0065] It is understandable that sleeves 700 are respectively sleeved on the left end and the right end of the quench branch pipe 200, as Figure 2 shown. The other end of the sleeve 700 is communicated with the air inlet pipe 110. The cold air sequentially passes through the air inlet pipe 110, the sleeve 700 and the quench branch pipe 200, and then blows towards the brick surface through the air outlet holes.

[0066] It is understandable that the sleeve 700 is in the shape of a right angle or a rounded corner, etc.

[0067] In some embodiments, the quench branch pipe 200 and the sleeve 700 can be locked by means of a sleeve, screw connection, welding, etc.

[0068] In this embodiment, the quench branch pipe 200 and the sleeve 700 are locked and connected by a fastener 800, as Figure 3 shown, to prevent the cold air used for cooling from leaking through the gap between the quench branch pipe 200 and the sleeve 700, which affects the cooling of the brick blank.

[0069] It is understandable that the fastener 800 is a hose clamp such as an American hose clamp, a German hose clamp or a British hose clamp for connecting a soft pipe and a hard pipe. The hose clamp corresponds to the outer end faces of the quench branch pipe 200 and the sleeve 700, so as to lock the quench branch pipe 200 and the sleeve 700.

[0070] It is understandable that since the opposite ends of the quench branch pipe 200 respectively penetrate into the sleeve 700, one end of the adjustment rod 900 penetrates through the sleeve 700, and the adjustment handle 920 is located outside the sleeve 700. Specifically, an opening is provided at the end of the sleeve 700 far from the quench branch pipe 200, and the adjustment rod 900 penetrates through the opening.

[0071] It is understandable that the cross-section of the adjustment rod 900 corresponds to the cross-section of the opening, so that the adjustment component is horizontally transported, and the adjustment component is prevented from shifting due to the action of gravity.

[0072] In some embodiments, the opening is a through hole, and the adjusting rod 900 can be a round rod or a square rod. By pushing and pulling the adjusting handle 920 left and right, the air volume and temperature output from the air outlet holes can be adjusted.

[0073] In other embodiments, the opening is an internal threaded hole, and the adjusting rod 900 is a threaded rod. By rotating the adjusting handle 920, the air volume and temperature can be adjusted. And in the absence of external force, the adjusting assembly and the rapid cooling branch pipe 200 are relatively fixed, preventing the cold air pressure from forcing the two regulating valve plates 910 to move towards each other.

[0074] Furthermore, the adjusting rod 900 is provided with scales. After pulling or rotating the adjusting handle 920, the position of the regulating valve plate 910 can be quickly obtained through the scales, facilitating the digital adjustment of the air volume and temperature.

[0075] In this embodiment, a pipe nut 710 is connected to the sleeve 700 at the opening. As Figure 2 shown, without drilling the opening, the adjusting rod 900 can be simply and quickly threaded through the pipe nut 710.

[0076] It can be understood that connecting plates 500 are horizontally connected to both sides of the kiln wall, as Figure 2 and Figure 3 shown. The connecting plates 500 are provided with connection holes that are vertically opposite to the rapid cooling branch pipes 200, and a locking member 600 for connecting the rapid cooling branch pipes 200 is inserted through the connection holes, as Figure 2 shown. Specifically, the connecting plates 500 extend in a direction away from the kiln furnace 100, that is, the connecting plates 500 extend left or right.

[0077] It can be understood that the connecting plates 500 are provided with a plurality of connection holes spaced apart in the front-back direction. The connection holes extend vertically and penetrate through the upper and lower end faces of the connecting plates 500. Each rapid cooling branch pipe 200 extending outside the kiln furnace 100 has two corresponding connection holes at its two ends, respectively, either upward or downward.

[0078] With this arrangement, the connecting plates 500 and the kiln wall are relatively fixed. Therefore, when the locking member 600 connecting the rapid cooling branch pipes 200 is inserted through the connection holes and fixed relative to the connecting plates 500, the rapid cooling branch pipes 200 are relatively fixed to the kiln furnace 100, strengthening the stability of the rapid cooling branch pipes 200 and the kiln furnace 100, and preventing the packing member 400 from affecting the relative position of the rapid cooling branch pipes 200 and the kiln furnace 100 when being inserted into the adjustment holes 150.

[0079] In some embodiments, the locking member 600 may be a linear motion mechanism such as a cylinder or a lead screw motor. Specifically, the linear motion mechanism is connected to the connecting plate 500, and the output end of the linear motion mechanism passes through the connecting hole and is connected to the quench branch pipe 200. By starting the linear motion mechanism, the height position of the quench branch pipe 200 is adjusted.

[0080] In this embodiment, the locking member 600 is an adjusting bolt 610 and a locking nut 620, as Figure 3 shown. Specifically, the adjusting bolt 610 and the locking nut 620 are threadedly connected. When they are respectively connected to the connecting plate 500 and the quench branch pipe 200 and rotated relative to each other, the height position of the quench branch pipe 200 can be adjusted.

[0081] In some embodiments, the connecting plate 500 and the locking nut 620 are rotatably connected, the connecting hole is a through hole, one end of the adjusting bolt 610 is connected to and relatively fixed to the outer end face of the quench branch pipe 200, and the other end of the adjusting bolt 610 passes through the connecting hole and is threadedly connected to the locking nut 620. By turning the locking nut 620, the relative positions of the locking nut 620 and the adjusting bolt 610 are changed, thereby realizing the adjustment of the height position of the quench branch pipe 200.

[0082] In this embodiment, the outer end face of the quench branch pipe 200 is rotatably connected to the locking nut 620, the connecting hole is an internal thread hole, and one end of the adjusting bolt 610 passes through the connecting hole in a threaded manner and is threadedly connected to the locking nut 620. The adjusting bolt 610 and the locking nut 620 are threadedly connected, and their relative positions are fixed. By turning the adjusting bolt 610, the vertical position of the adjusting bolt 610 relative to the connecting hole is adjusted to realize the adjustment of the height position of the quench branch pipe 200.

[0083] Furthermore, the locking member 600 can be connected to the hose clamp, that is, the locking nut 620 is rotatably connected to the hose clamp or the adjusting bolt 610 is connected to the hose clamp, as Figure 3 shown. The locking member 600 adjusts the height position of the quench branch pipe 200 by driving the hose clamp to move up and down.

[0084] It can be understood that the connecting plate 500 is connected with a fixing plate 300 extending vertically. The fixing plate 300 is connected to the kiln wall, so that the connection between the connecting plate 500 and the kiln wall is more stable and simple. Specifically, fixing plates 300 are provided on both kiln walls of the kiln furnace 100 in the left-right direction, as Figure 2 and Figure 3 shown. The fixing plate 300 is provided with a plurality of mounting holes 310 corresponding to a plurality of adjustment holes 150 on the kiln wall. The shapes and sizes of the mounting holes 310 are the same as and correspond to those of the adjustment holes 150 one by one, so that the quench branch pipe 200 can pass through the kiln wall and the fixing plate 300 and slide in the adjustment holes 150 and the mounting holes 310.

[0085] It can be understood that the fixing plate 300 is connected to the kiln wall of the kiln furnace 100, so that the multiple adjusting holes 150 are relatively fixed with respect to the kiln furnace 100. Therefore, when the rapid cooling branch pipe 200 is relatively fixed in the adjusting hole 150 through the filling member 400, the rapid cooling branch pipe 200 and the kiln furnace 100 are relatively fixed.

[0086] In some embodiments, the kiln furnace 100 is provided with two fixing plates 300. All the mounting holes 310 corresponding to the left ends of the multiple rapid cooling branch pipes 200 are arranged on one fixing plate 300, and all the mounting holes 310 corresponding to the right ends of the multiple rapid cooling branch pipes 200 are arranged on the other fixing plate 300. The transfer stick 140 for conveying the green bricks is located between the two fixing plates 300.

[0087] In this embodiment, the kiln furnace 100 is provided with four fixing plates 300, so that the multiple mounting holes 310 corresponding to the left ends and the right ends of the multiple rapid cooling branch pipes 200 located above are respectively arranged in two symmetrically left and right fixing plates 300, and the multiple mounting holes 310 corresponding to the left ends and the right ends of the multiple rapid cooling branch pipes 200 located below are respectively arranged in two symmetrically left and right fixing plates 300, that is, the transfer stick 140 is located between the two upper fixing plates 300 and the two lower fixing plates 300, which is convenient for installing and maintaining the transfer stick 140.

[0088] It can be understood that the multiple air outlet holes on the rapid cooling branch pipe 200 are all located between the two adjusting holes 150, ensuring that the air outlet holes only blow air into the interior of the kiln furnace 100.

[0089] In some embodiments, a connecting plate 500 is connected to the upper end or the lower end of the fixing plate 300, that is, the fixing plate 300 and the connecting plate 500 form an L-shaped plate, and the connecting plate 500 is located at one end of the fixing plate 300 facing the rapid cooling branch pipe 200.

[0090] In this embodiment, connecting plates 500 are connected to both the upper end and the lower end of the fixing plate 300, that is, the fixing plate 300 and the two connecting plates 500 form a U-shaped plate. As Figure 2 and Figure 3 shown, when the fixing plate 300 is installed on the kiln furnace 100, there is no need to distinguish whether the connecting plate 500 is installed close to the rapid cooling branch pipe 200, making the installation of the fixing plate 300 and the kiln wall more convenient.

[0091] It can be understood that the fixing plate 300 and the connecting plate 500 are integrally formed.

[0092] A kiln 100 according to an embodiment of the present utility model includes a device for efficiently adjusting the temperature difference in the cooling zone of the kiln. The kiln 100 can adjust the relative position of the rapid cooling branch pipe 200 and the green brick through the locking member 600. The kiln 100 can also adjust the air volume for cooling the green brick respectively through the adjusting assembly. Both methods can reduce the temperature difference of the cross-section, thereby solving the problems of large flatness, large deformation amount and low qualification rate of the green brick.

[0093] It can be understood that the kiln 100 includes an air inlet pipe 110, an air valve 120 and a telescopic pipe 130. The air inlet pipe 110 is communicated with a plurality of air valves 120. The opposite ends of the telescopic pipe 130 are respectively communicated with the air valve 120 and the sleeve 700. Specifically, the cold air input by the air inlet pipe 110 sequentially passes through the communicated air valve 120, the telescopic pipe 130 and the sleeve 700 and then is input into the rapid cooling branch pipe 200. The air valve 120 adjusts the cold air volume of the rapid cooling branch pipe 200, thereby further adjusting the temperature difference of the cross-section, making the air volume adapt to the needs of different products and meeting different cooling effects.

[0094] It can be understood that since the rapid cooling branch pipe 200 adjusts its vertical relative position with the kiln 100 through the locking member 600, when the height position of the rapid cooling branch pipe 200 is adjusted, the telescopic pipe 130 can automatically stretch to always realize the connection between the air valve 120 and the sleeve 700, as Figure 2 shown.

[0095] It can be understood that the air inlet pipe 110 extends in the front-rear direction, which is convenient for a plurality of air valves 120 respectively communicated with one end of a plurality of rapid cooling branch pipes 200 to be communicated in one air inlet pipe 110, that is, one end of a plurality of extremely rapid cooling branch pipes 200 enters air through one air inlet pipe 110, making the structure of the kiln 100 simple.

[0096] It can be understood that since cold air needs to be input at both the left end and the right end of the rapid cooling branch pipe 200, and a plurality of symmetric rapid cooling branch pipes 200 are provided above and below the transmission rod 140. Therefore, the kiln 100 is provided with at least two air inlet pipes 110 to respectively meet the air inlet at the left end and the right end of the rapid cooling branch pipe 200.

[0097] In this embodiment, the kiln 100 is provided with four air inlet pipes 110, as Figure 1 shown. The two air inlet pipes 110 located above are respectively responsible for the air inlet at the left end and the air inlet at the right end of the plurality of rapid cooling branch pipes 200 located above. The two air inlet pipes located below are respectively responsible for the air inlet at the left end and the air inlet at the right end of the plurality of rapid cooling branch pipes 200 located below.

[0098] In some embodiments, the air valve 120 is a calibrated aluminum alloy butterfly valve. The calibrated aluminum alloy butterfly valve can make the output air volume visual, which is convenient for adjusting the air volume. The aluminum alloy butterfly valve has the advantages of strong corrosion resistance, good sealing performance, flexible and labor-saving operation, etc.

[0099] The preferred embodiments of the present utility model have been specifically described above. However, the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. These equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
