Description

Technical Field

[0001] This application relates to the technical field of ceramic blank drying, and particularly to a ceramic blank drying room. Background Art

[0002] After the ceramic blank is formed, it needs to be placed in a drying room for drying. Commonly, the method of heating and humidifying hot air is adopted. During drying, the hot air is transported through a pipeline and enters the room through the hot air holes on the side wall of the pipeline, which is convenient for drying the blank.

[0003] A plurality of atomizing nozzles perpendicular to the hot air conveying direction are provided at the air inlet end of the pipeline. When the humidity in the room is low, the atomizing nozzles atomize and spray water, so that the water mist is driven to move into the room during the flow of the hot air, increasing the humidity in the room.

[0004] Since the water contains impurities, there is a possibility of clogging the atomizing nozzles, which affects the working efficiency. Summary of the Invention

[0005] In order to reduce the possibility of nozzle clogging, this application provides a ceramic blank drying room.

[0006] The ceramic blank drying room provided by this application adopts the following technical solutions: A ceramic blank drying room includes a room body. A partition is provided in the middle of the room body in the length direction. Air ducts are provided on both sides of the partition along the length direction of the room body. Control valves are provided on the fans. The ends of the air ducts close to each other are both connected to the same conveying pipe perpendicular to the length direction of the air ducts. A plurality of air holes are opened on the side walls of the air ducts. A plurality of stirring fans and dehumidifying fans are provided on the room body. A plurality of relatively arranged atomizing assemblies are provided inside the ends of the air ducts close to each other. The atomizing assemblies in the same air duct are all connected to the same water pipe, and a filtering assembly is provided on the water pipe.

[0007] By adopting the above technical solutions, the hot air enters the room body through the air holes on the air ducts. When it is necessary to humidify the room body, water is transported to the atomizing assemblies through the water pipe, and then the water is atomized and sprayed into the hot air in the air ducts. The stirring fans are convenient for driving the hot air to be evenly dispersed in the room body. When the humidity in the room body is high, the spraying of water mist is stopped and the moisture in the room body is discharged through the dehumidifying fans. Moreover, when the water is transported through the water pipe, the filtering assembly contacts and filters the water, thereby removing the impurities in the water and reducing the possibility of impurity clogging the nozzles.

[0008] Optionally, one end of the water pipe close to the atomization component is vertical and has a square cross-section. The filter component includes a filter rack that horizontally penetrates the water pipe and is slidably connected to the water pipe. A fixing plate is provided in the middle of the filter rack in the length direction. Screens are provided on both sides of the lower side of the fixing plate. When filtering through the screens, both ends of the screens are inserted into the side wall of the water pipe.

[0009] By adopting the above technical solution, when filtering impurities in water, one of the sieve plates is inserted into the water pipe. At this time, water passes through the sieve plate, and the impurities in the water are retained on the sieve plate. When the impurities on the sieve plate inserted into the water pipe need to be cleaned, the filter rack is driven to slide so that the sieve plate for receiving impurities moves to the outside of the water pipe, and the other sieve plate is inserted into the water pipe, reducing the adverse impact on impurity filtration and the possibility of nozzle blockage.

[0010] Optionally, the ends of the screens close to each other are hinged to the partition plate. Collection hoppers corresponding to the screens and located below the screens are provided on both sides of the outside of the water pipe.

[0011] By adopting the above technical solution, when the sieve plate is inserted into the water pipe, the sieve plate is perpendicular to the length direction of the water pipe. When the impurities on the sieve plate need to be cleaned, the filter rack is driven to move so that the sieve plate to be cleaned moves to the upper side of the corresponding collection hopper. At this time, the sieve plate rotates downward along its hinge point, which is convenient for cleaning, and the other sieve plate is inserted into the water pipe to filter impurities, reducing the possibility of nozzle blockage.

[0012] Optionally, one end of the filter rack is fixedly connected to a fixed rod, and a first hydraulic cylinder is installed on one side of the outside of the water pipe. The telescopic rod of the first hydraulic cylinder is fixedly connected to the fixed rod.

[0013] By adopting the above technical solution, the telescopic rod of the first hydraulic cylinder extends or contracts, so as to facilitate driving the filter rack to move through the driving rod, so as to facilitate replacing the sieve plate in the water pipe and cleaning the impurities on the sieve plate.

[0014] Optionally, the atomization component includes a housing communicated with the water pipe. One side of the housing close to the inside of the air duct is semicircular and a through hole is provided in the middle. An arc-shaped plate is slidably connected to the outer side wall of the semicircular side of the housing. Two groups of nozzles located at the ends of the arc-shaped plate and capable of communicating with the through hole are provided on the arc-shaped plate. A sliding component for driving the arc-shaped plate to slide is provided on the water pipe.

[0015] By adopting the above technical solution, two groups of nozzles are installed on the arc-shaped plate. During use, one of the groups of nozzles is communicated with the inside of the housing through the through hole, which is convenient for atomizing and spraying the water in the housing. When the nozzle for spraying water mist is blocked, the sliding component drives the arc-shaped plate to drive the nozzle to slide along the semicircular surface of the housing until the other group of nozzles is communicated with the housing, so as to facilitate replacing the nozzle and reducing the possibility of nozzle blockage.

[0016] Optionally, the sliding assembly includes sector plates fixedly connected to both sides of the arc-shaped plate and rotatably connected to the housing, and a motor fixedly connected to the water pipe is installed on one of the sector plates.

[0017] By adopting the above technical solution, the motor drives the sector plate to rotate, thereby driving the arc-shaped plate to drive the nozzle to slide along the semi-circular surface of the housing, facilitating the replacement of the nozzle and reducing the possibility of the nozzle being blocked and affecting the spraying of water mist.

[0018] Optionally, a dredging needle is slidably connected to each of the nozzles. Driving blocks corresponding to the dredging needles one by one are provided at both ends of the semi-circular side of the housing. The driving blocks are arranged in a frustum shape with a gradually decreasing diameter. The driving blocks are inserted into and slidably connected to the housing, and a first spring is installed between the driving blocks and the housing.

[0019] By adopting the above technical solution, when the arc-shaped plate slides, it first contacts the driving block at the end of the housing. Continuing to move the arc-shaped plate, at this time, the end of the arc-shaped plate is squeezed along the side wall of the driving block until the driving block completely enters the housing. When the arc-shaped plate slides to align the blocked nozzle with the corresponding driving block, the first spring resumes deformation and pushes the driving block to move towards the direction close to the dredging needle until one end of the dredging needle passes through the hole in the corresponding nozzle, thereby facilitating the dredging of the nozzle and reducing the possibility of the nozzle being blocked.

[0020] Optionally, the arc-shaped plate is provided with limiting rods corresponding to the dredging needles and located on both sides of the corresponding dredging needles. The limiting rods on both sides of the dredging needle are slidably connected to the dredging needle in a direction of approaching or separating from each other. The limiting rods on the same side of the same group of dredging needles are fixedly connected to the same driving rod, and a driving member for driving the driving rod to move towards the direction of approaching each other is provided on the water pipe.

[0021] By adopting the above technical solution, when the nozzle is communicated with the inside of the housing through the through hole, the driving member drives the driving rod to drive the limiting rod to move towards the direction close to the corresponding nozzle and insert into the dredging needle, thereby facilitating the limiting of the dredging needle and reducing the possibility that the water in the housing enters the nozzle and pushes the dredging needle to block the nozzle, and reducing the adverse impact on the humidification efficiency.

[0022] Optionally, the sides of the driving rods away from each other are both provided with inclined surfaces inclined in the direction away from each other. The driving member includes sliding rods corresponding to the driving rods one by one and having one end inserted and slidably connected to the arc-shaped plate. The sliding rods are perpendicular to the limiting rods. The ends of the sliding rods on both sides of the same nozzle away from the driving rods are provided with inclined surfaces inclined in the direction away from the driving rods and away from each other. A driving plate capable of abutting against the sliding rods on both sides of the same nozzle at the same time is provided outside the housing, and a second hydraulic cylinder for driving the driving plate to squeeze the sliding rods is provided on the water pipe.

[0023] By adopting the above technical solution, the arc-shaped plate is rotated until the sliding rod on one side of the nozzle is located at the through hole. At this time, the second hydraulic cylinder and the driving plate are used to squeeze the sliding rod to move towards the driving rod and push the limiting rod into the corresponding dredging needle. The arc-shaped plate is continuously moved until the inclined surface on the sliding rod on the other side of the same dredging needle abuts against the side wall of the driving plate. The arc-shaped plate is continuously driven to move. At this time, the driving plate squeezes the sliding rod along the inclined surface until the nozzle communicates with the inside of the housing. At this time, both sides of the dredging needle are limited by the corresponding limiting rods, reducing the possibility that the water in the housing enters the nozzle and pushes the dredging needle to block the nozzle, and reducing the adverse impact on the humidification efficiency.

[0024] To sum up, the present application includes at least one of the following beneficial technical effects: 1. When filtering impurities in water, one of the sieve plates is inserted into the water pipe. At this time, the water passes through the sieve plate, and the impurities in the water are intercepted on the sieve plate. When the impurities on the sieve plate inserted into the water pipe need to be cleaned, the filter rack is driven to slide so that the sieve plate for receiving impurities moves to the outside of the water pipe, and the other sieve plate is inserted into the water pipe, reducing the adverse impact on impurity filtration; 2. Two groups of nozzles are installed on the arc-shaped plate. During use, one group of nozzles communicates with the inside of the housing through the through hole, which is convenient for atomizing and spraying the water in the housing. When the nozzle for spraying water mist is blocked, the sliding assembly drives the arc-shaped plate to drive the nozzle to slide along the semicircular surface of the housing until the other group of nozzles communicates with the housing, so as to facilitate the replacement of the nozzle and reduce the possibility of nozzle blockage; 3. When the arc-shaped plate slides, it first contacts the driving block at the end of the housing. The arc-shaped plate is continuously moved. At this time, the end of the arc-shaped plate is squeezed along the side wall of the driving block until the driving block completely enters the housing. When the arc-shaped plate slides until the blocked nozzle is aligned with the corresponding driving block, the first spring resumes deformation and pushes the driving block towards the dredging needle until one end of the dredging needle passes through the hole on the corresponding nozzle, so as to facilitate the dredging of the nozzle and reduce the possibility of nozzle blockage.

Detailed implementation manners

[0035] The following further describes the present application in detail with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses a ceramic blank drying room. Refer to Figure 1 and Figure 2, a ceramic blank drying room includes a horizontally arranged room body 1. A vertical partition 11 is fixedly connected to the middle of the room body 1 in the length direction. A conveying pipe 2 parallel to the partition 11 is fixedly connected to the upper side of the partition 11. Air pipes 21 that are horizontal and arranged along the length direction of the room body 1 are fixedly connected and communicated on both sides of the middle of the conveying pipe 2. A plurality of air holes 211 arranged along the length direction of the air pipe 21 are opened on both sides of the air pipe 21.

[0037] Refer to Figure 2 and Figure 3 , control valves 3 are provided at the ends of the air pipes 21 that are close to each other. The control valve 3 includes a baffle 31 for blocking the air pipe 21. A horizontal blocking rod 32 that is inserted through and fixedly connected to the middle of the baffle 31 and is rotatably connected to the air pipe 21 is provided. One end of the blocking rod 32 away from the baffle 31 passes through the air pipe 21 and the room body 1 and is fixedly connected to a handle 33. When the baffle 31 is horizontal, the air pipe 21 is opened. When the baffle 31 is vertical, the baffle 31 blocks the corresponding air pipe 21.

[0038] Refer to Figure 2 and Figure 3 , two sets of atomizing assemblies 4 are provided inside the air pipes 21 at the ends that are close to each other. Each set of atomizing assemblies 4 is set to two and is arranged oppositely. An installation pipe 445 is fixedly connected and communicated to the middle of the side of each set of atomizing assemblies 4 that is away from each other. One end of the installation pipe 445 away from the corresponding atomizing assembly 4 passes through the side wall of the air pipe 21 and is fixedly connected to the air pipe 21.

[0039] Refer to Figure 2 and Figure 3 , the two installation pipes 445 on the same side of the air pipe 21 are fixedly connected to the same vertical fixed pipe 51. The upper ends of the fixed pipes 51 on both sides of the air pipe 21 are bent at a right angle towards the direction of approaching each other and are communicated with a vertical water pipe 52. The upper end of the water pipe 52 is bent at a right angle to one side and a filtering assembly 6 for filtering impurities is provided at the vertical end of the water pipe 52. A plurality of evenly distributed stirring fans 12 are installed on the room body 1. Exhaust fans 13 installed on the room body 1 are provided on the side of each stirring fan 12 close to the air pipe 21.

[0040] Hot air is transported to the air duct 21 through the delivery pipe 2 and enters the room body 1 through the air holes 211 on the air duct 21. When it is necessary to close one of the air ducts 21, the driving handle 33 drives the plugging rod 32 to rotate, thereby driving the baffle 31 to rotate to the vertical position to block the air duct 21. When it is necessary to humidify the room body 1, water is transported to the atomizing assembly 4 through the water pipe 52, the fixed pipe 51 and the installation pipe 445, so that the water is atomized and sprayed into the hot air in the air duct 21. The stirring fan 12 facilitates driving the hot air to be evenly dispersed in the room body 1. When the humidity in the room body 1 is high, the spraying of water mist is stopped and the moisture in the room body 1 is discharged through the dehumidifying fan 13. When the water is transported through the water pipe 52, the filtering assembly 6 comes into contact with the water and filters it, thereby removing impurities in the water and reducing the possibility of the impurities clogging the nozzle 43.

[0041] Refer to Figure 3 and Figure 4 The cross-section of the vertical end of the water pipe 52 is square. The filtering assembly 6 includes a horizontal filtering frame 61. A sliding hole 521 penetrating the side walls on both sides of the water pipe 52 is opened at the vertical end of the water pipe 52. One end of the filtering frame 61 is inserted into the sliding hole 521 and is slidably connected to the water pipe 52. A vertical fixing plate 62 is fixedly connected to the middle of the filtering frame 61 in the length direction. Sieve plates 63 that can adapt to the inside of the water pipe 52 are provided on both sides of the lower side of the fixing plate 62. The ends of the sieve plates 63 close to each other are hinged to the side wall of the fixing plate 62.

[0042] When one end of the filtering frame 61 is flush with the side wall of the water pipe 52, the fixing plate 62 is located on the opposite side of the water pipe 52, and both ends of the sieve plate 63 are inserted into the side wall of the water pipe 52. The other sieve plate 63 is located outside the water pipe 52. Collection hoppers 64 corresponding to the sieve plates 63 and located below the sieve plates 63 are fixedly connected to both sides of the water pipe 52. A horizontal fixing rod 65 arranged along the length direction of the filtering frame 61 is fixedly connected to the outer side wall of one end of the filtering frame 61. The end of the fixing rod 65 away from the filtering frame 61 is bent to one side of the water pipe 52. A first hydraulic cylinder 66 facing the fixing rod 65 and parallel to the width direction of the air duct 21 is fixedly connected to the side of the water pipe 52 close to the fixing rod 65. The telescopic rod of the first hydraulic cylinder 66 is fixedly connected to the bent end of the fixing rod 65.

[0043] When filtering impurities in the water, one of the sieve plates 63 is inserted into the water pipe 52. At this time, the water passes through the sieve plate 63, and the impurities in the water are intercepted on the sieve plate 63. When the impurities on the sieve plate 63 inserted into the water pipe 52 need to be cleaned, the filtering frame 61 is driven to slide through the first hydraulic cylinder 66 and the fixing rod 65 so that the sieve plate 63 for receiving impurities moves to the outside of the water pipe 52 and is located above the corresponding collection hopper 64. At this time, the sieve plate 63 rotates downward along its hinge point, which is convenient for cleaning, and the other sieve plate 63 is inserted into the water pipe 52 to filter impurities, reducing the possibility of the nozzle 43 being blocked.

[0044] Refer toFigure 5 and Figure 6 The atomizing assembly 4 includes a horizontal housing 41. One side of the housing 41 away from the corresponding mounting pipe 445 is semicircular, and three through holes 411 arranged vertically are formed in the middle of the semicircular side of the housing 41. On one side of the housing 41 away from the corresponding mounting pipe 445, there is an arc-shaped plate 42 that abuts against and is slidably connected to the semicircular surface of the housing 41. At both ends of the arc-shaped plate 42 away from the housing 41, a group of spray nozzles 43 arranged along the width direction of the arc-shaped plate 42 are installed. In the embodiment of the present application, a group of spray nozzles 43 are set to three and can all communicate with the inside of the housing 41 through the through holes 411. A sliding assembly 7 for driving the arc-shaped plate 42 to slide is provided on the housing 41.

[0045] Referring to Figure 5 The sliding assembly 7 includes sector plates 71 that are adapted to the arc-shaped plate 42 and are correspondingly arranged on both sides of the arc-shaped plate 42 in the vertical direction. One end of the sector plate 71 away from the arc-shaped plate 42 is rotatably connected to the housing 41, and a motor 72 that is installed on one of the sector plates 71 and drives the sector plate 71 to rotate is fixedly connected to the lower side of the housing 41.

[0046] Referring to Figure 5 and Figure 6 Two groups of spray nozzles 43 are installed on the arc-shaped plate 42. During use, one group of spray nozzles 43 communicates with the inside of the housing 41 through the through holes 411, which is convenient for atomizing and spraying the water in the housing 41. When the spray nozzles 43 for spraying water mist are blocked, the motor 72 drives the sector plate 71 to rotate, thereby driving the arc-shaped plate 42 to drive the spray nozzles 43 to slide along the semicircular surface of the housing 41 until the other group of spray nozzles 43 communicates with the housing 41, so as to facilitate the replacement of the spray nozzles 43 and reduce the possibility of the spray nozzles 43 being blocked.

[0047] Referring to Figure 6 and Figure 7 In the spray nozzles 43, dredging needles 8 arranged along the length direction of the spray nozzles 43 are provided. On both sides of one end of the dredging needle 8 close to the arc-shaped plate 42, stabilizing rods 81 perpendicular to the length direction of the dredging needle 8 are fixedly connected. On both sides inside the spray nozzles 43, stabilizing grooves 431 adapted to the stabilizing rods 81 are formed. The stabilizing rods 81 are inserted into the corresponding stabilizing grooves 431 and are slidably connected to the spray nozzles 43 along the length direction of the spray nozzles 43. At one end of the stabilizing groove 431 away from the housing 41, there is a second spring 82 with one end fixedly connected to the inner side wall of the spray nozzle 43, and the other end of the second spring 82 is fixedly connected to the stabilizing rod 81. When the second spring 82 is in its original length, the stabilizing rod 81 is located at one end of the stabilizing groove 431 close to the housing 41, and the dredging needle 8 is located inside the spray nozzle 43.

[0048] At both ends of the housing 41 close to one side of the arc-shaped plate 42, there are driving blocks 412 corresponding to the spray heads 43 one by one. The driving blocks 412 are arranged in a frustum shape with a gradually decreasing diameter towards the side away from the inside of the housing 41. The housing 41 is provided with insertion slots 413 adapted to the driving blocks 412. The end with a larger diameter of the driving block 412 is inserted into the corresponding insertion slot 413 and is slidably connected to the housing 41. The driving block 412 can completely enter the insertion slot 413. In each of the insertion slots 413, there is a first spring 414 with one end fixedly connected to the side wall of the housing 41, and the other end of the first spring 414 is fixedly connected to the corresponding driving block 412.

[0049] Referring to Figure 8 and Figure 9 , on both sides of the spray head 43, there are sliding connections with limit rods 9 corresponding to the stabilizing rods 81 one by one, and one end of the limit rods 9 is inserted into the spray head 43 and is slidably connected to the spray head 43. When the second spring 82 is in its original length, the limit rods 9 can be inserted into the corresponding stabilizing rods 81 and limit the dredging needle 8. At the ends of the limit rods 9 on the same side of the same group of spray heads 43 away from the corresponding spray heads 43, there are connecting rods 91 arranged along the width direction of the arc-shaped plate 42. In the middle of the connecting rods 91 on both sides of the same group of spray heads 43, there are driving rods 92 facing away from the connecting rods 91.

[0050] The end of the driving rod 92 away from the corresponding connecting rod 91 is set as an inclined surface that slopes upward and towards the side close to the corresponding connecting rod 91. In the arc-shaped plate 42, there is a cavity 421 adapted to the driving rod 92 and the connecting rod 91. The end of the driving rod 92 away from the connecting rod 91 is fixedly connected to a third spring 93, and the end of the third spring 93 away from the driving rod 92 is fixedly connected to the inner side wall of the arc-shaped plate 42. When the third spring 93 is in its original length, the limit rod 9 is not inserted into the corresponding stabilizing rod 81, and there is a driving member 94 on the mounting rod for driving the driving rod 92 to move towards the corresponding spray head 43.

[0051] Referring to Figure 5 , Figure 8 and Figure 9 , the driving member 94 includes sliding rods 941 corresponding to the driving rods 92 one by one, located at the end of the driving rod 92 away from the corresponding connecting rod 91 and parallel to the connecting rod 91. The lower end of the sliding rod 941 can abut against the inclined surface on the driving block and squeeze the driving rod 92 to move towards the corresponding spray head 43. The upper ends of the sliding rods 941 all pass through the arc-shaped plate 42 and are slidably connected to the arc-shaped plate 42. The upper ends of the sliding rods 941 on both sides of the same group of spray heads 43 are set as inclined surfaces that slope upward and away from each other.

[0052] On the upper side of the arc-shaped plate 42, there is a driving plate 942 that pushes the sliding rod 941 to move. On the side of the driving plate 942 away from the arc-shaped plate 42, a second hydraulic cylinder 943 is installed. On the upper side of the installation pipe 445, fixing frames are fixedly connected. One end of the second hydraulic cylinder 943 away from the driving plate 942 is fixedly connected to the fixing frame.

[0053] When the arc-shaped plate 42 slides, it first contacts the driving block 412 at the end of the housing 41. Continuing to move the arc-shaped plate 42, at this time, the end of the arc-shaped plate 42 is squeezed along the side wall of the driving block 412 until the driving block 412 completely enters the housing 41. When the arc-shaped plate 42 slides to the position where the blocked nozzle 43 is aligned with the corresponding driving block 412, the first spring 414 resumes deformation and pushes the driving block 412 to move towards the direction close to the dredging needle 8 until one end of the dredging needle 8 passes through the hole in the corresponding nozzle 43, so as to facilitate the dredging of the nozzle 43 and reduce the possibility of the nozzle 43 being blocked.

[0054] Drive the arc-shaped plate 42 to rotate until the sliding rod 941 on one side of the nozzle 43 is located at the through hole 411. At this time, the sliding rod 941 is squeezed by the second hydraulic cylinder 943 and the driving plate 942 to move towards the direction close to the driving rod 92 and push the limiting rod 9 into the corresponding dredging needle 8. Continuing to move the arc-shaped plate 42 until the inclined surface on the sliding rod 941 on the other side of the same dredging needle 8 abuts against the side wall of the driving plate 942. Continuing to drive the arc-shaped plate 42 to move, at this time, the driving plate 942 squeezes the sliding rod 941 along the inclined surface until the nozzle 43 communicates with the inside of the housing 41. At this time, both sides of the dredging needle 8 are limited by the corresponding limiting rods 9, reducing the possibility that the water in the housing 41 enters the nozzle 43 and pushes the dredging needle 8 to block the nozzle 43.

[0055] The implementation principle of an embodiment of a ceramic blank drying room in this application is as follows: Hot air enters the room body 1 through the air holes 211. When it is necessary to close one of the air ducts 21, drive the baffle 31 to rotate to the vertical position to block the air duct 21. When it is necessary to humidify the room body 1, atomize the water and spray it into the hot air in the air duct 21. The stirring fan 12 facilitates driving the hot air to be evenly dispersed in the room body 1. When the humidity in the room body 1 is high, stop spraying the water mist and exhaust the moisture in the room body 1 through the exhaust fan 13. And when the water is conveyed through the water pipe 52, the screen contacts the water and filters it, thereby removing the impurities in the water and reducing the possibility of the impurities blocking the nozzle 43.

[0056] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
