Description

Technical Field

[0001] The present application relates to the field of ceramic production equipment, and in particular to a drying equipment for industrial ceramic production. Background Art

[0002] Industrial ceramics are fine ceramics used in industrial production and industrial products. They have superior properties such as high temperature resistance, corrosion resistance, wear resistance, and erosion resistance. They can replace metals and organic polymer materials and are used in harsh working environments. They are key materials for traditional industrial transformation, emerging industries and high-tech development. Compared with traditional ceramics, industrial ceramics pay more attention to functionality, durability and adaptability to extreme environments, and are widely used in industrial scenarios such as high temperature, high pressure, strong corrosion, and high wear.

[0003] The production process of industrial ceramics usually includes a series of processes such as raw material screening, pretreatment, green body forming, drying and dehydration, sintering and shaping, processing and post-processing. Among them, the drying process is a key step after green body forming and before sintering and shaping. Its core purpose is to remove free water and some adsorbed water in the green body, while releasing the internal stress of the green body, ensuring that the green body has sufficient strength and dimensional stability, laying the foundation for subsequent sintering and shaping, and preventing cracking and deformation during the sintering process.

[0004] The drying operation of ceramics is usually carried out in drying equipment. The current Chinese patent application with the announcement number CN111637689A discloses a vacuum drying oven, which is essentially a drying equipment, including a main box body with an openable and closable door on the side of the main box body; a drying cabinet is installed inside the main box body, and a number of drying chambers are provided inside the drying cabinet. The drying chamber is used to place ceramic blanks that need to be dried; a heating component is installed on the back of the drying chamber, which can heat the air inside the drying chamber and then heat and dry the ceramic blanks to remove moisture.

[0005] The drying operation of ceramic embryos requires continuous heating and drying of the embryos for a period of time. Since industrial ceramics are mostly small-volume precision components, when the number of ceramic embryos is small, the space occupied in the drying cabinet is small, and the heating component provides heat for the entire drying cabinet, so there is energy waste; and in the drying operation of ceramic embryos, it is necessary to wait for the ceramic embryos in the drying cabinet to be dried and cooled down before a new batch of embryos can be placed in the drying cabinet for a new round of drying operations, which leads to the equipment production capacity not meeting the standards and a long waiting time, resulting in low overall production efficiency of the drying box, which needs to be improved. Summary of the Invention

[0006] Based on this, the present application provides a drying equipment for industrial ceramic production, which can place the ceramic blank in the equipment assembly in real time for drying operations. While ensuring that the equipment production capacity meets the standards per unit time, it can also reduce waiting time and improve the overall production efficiency of the drying box.

[0007] The present application provides a drying equipment for industrial ceramic production using the following technical solutions:

[0008] A drying device for industrial ceramic production includes an equipment assembly, wherein the outer peripheral surface of the equipment assembly is provided with a plurality of drying stations, each of which is provided with a placement unit for placing ceramic blanks; a heating unit is provided inside the equipment assembly for thermally drying each group of placement units, and an openable and closable barrier mechanism is provided between each placement unit and the heating unit to independently control the thermal drying of each group of placement units;

[0009] The placement unit includes a station base slidably mounted on the drying station, a placement seat rotatably mounted on the station base, and a cage member positioned on the placement seat. A gear transmission mechanism is provided between the placement seat and the station base to achieve rotational positioning of the placement seat. The cage member has multiple accommodating chambers for placing ceramic blanks.

[0010] The placement unit also includes a driving component for driving the workstation base to move. The moving direction of the workstation base is the same as the radial direction of the equipment assembly. In the initial state, the workstation base is located at the outer edge of the equipment assembly. At this time, the drying station and the heating unit are separated by a blocking mechanism.

[0011] By adopting the above technical solution, in the initial state, each drying station is isolated from the heating unit, and the heated air inside the heating unit will not leak to each group of placement units; when the ceramic blank needs to be hot-dried, the ceramic blank is placed in the accommodating chamber of the cage component, and the cage component is positioned and placed on the placement seat of one group of placement units. The driving component is controlled to pull the station base of the placement unit inward, which can move the station base toward the heating unit, and the corresponding blocking mechanism is opened, so that the ceramic blank can be hot-dried normally, and the drying operations of each group of placement units do not affect each other.

[0012] During the drying process of the ceramic body, if a new ceramic body needs to be dried, the new ceramic body can be placed in the accommodating chamber of the cage component, and the cage component is positioned and placed on the placement seat of another set of placement units, and then sent into the equipment assembly for hot drying. Based on this, the drying equipment can continuously dry each ceramic body produced by the front-end process, and the drying time of the ceramic bodies on each set of placement units is staggered, which can ensure that there is always a drying station in a usable state, so that each ceramic body can be dried in real time. While ensuring that the equipment production capacity per unit time meets the standard, it can also reduce waiting time, thereby improving the overall production efficiency of the drying box.

[0013] Optionally, a construction chamber is provided on the side of the placement seat close to the heating unit, a positioning plate frame is provided inside the construction chamber, and a plurality of limiting columns are vertically provided on the top edge of the positioning plate frame; a supporting base plate is fixed to the bottom of the cage member, and a plurality of limiting grooves are provided on the outer peripheral surface of the supporting base plate, and each limiting column is respectively clamped in each limiting groove;

[0014] A vertical slide groove is provided on the inner wall of the structural chamber, and a freely sliding plug-in column is provided inside the vertical slide groove; a guide groove is provided on the outer peripheral surface of the positioning plate frame, and the guide groove is bent and extended along the axial direction of the positioning plate frame, and the plug-in column is normally inserted in the guide groove;

[0015] Several extension columns are fixed to the bottom of the positioning plate frame, and the placement seat is provided with a first waist hole for the extension column to pass through; a counterweight part is provided at the bottom of the extension column, which is used to make the positioning plate frame normally press against the bottom wall of the construction room under the action of gravity, and the positioning plate frame is linked to the gear transmission mechanism.

[0016] By adopting the above-mentioned technical solution, the present application cooperates with the extension column and the first waist hole, so that the positioning plate frame can not only move along the height direction of the construction chamber, but also rotate circumferentially around the central axis of the positioning plate frame itself along the arc direction of the first waist hole; when the ceramic embryo is placed inside the cage body component and positioned on the positioning plate frame, each limiting column on the positioning plate frame can respectively enter each limiting groove on the outer peripheral surface of the supporting bottom plate, thereby realizing the circumferential linkage setting of the cage body component and the positioning plate frame, so that the cage body component can rotate together with the positioning plate frame.

[0017] When the placement unit enters the inner side of the equipment assembly to perform the hot drying operation of the ceramic embryo, the gear transmission mechanism can force the positioning plate frame to move in the vertical direction, thereby improving the heating uniformity of the ceramic embryo; and when the positioning plate frame is forced to move upward, it can move upward along the vertical slide groove with the plug-in column. When the plug-in column moves upward to the limit position, the positioning plate frame continues to be forced to move upward. The cooperation between the plug-in column and the guide groove can make the positioning plate frame rotate around its own central axis, and then the ceramic embryo can be dried in all directions, which helps to further enhance the heating uniformity of the ceramic embryo and ensure that the ceramic has good molding quality.

[0018] Optionally, the gear transmission mechanism includes a lifting column, a driving gear, a transmission gear and a drive motor, wherein the driving gear is rotatably mounted on the workstation base, the drive motor is coaxially connected to the driving gear to drive the driving gear to rotate; the transmission gear is rotatably mounted on the placement seat, and the transmission gear and the driving gear are meshed for transmission;

[0019] The outer circumference of the lifting column is polygonal, and the lifting column is movably inserted into the bottom wall of the structural chamber, and the lifting column is facing the bottom of the positioning plate frame; the transmission gear is coaxially fixed with a connecting rod, and the connecting rod extends into the interior of the lifting column, and a spiral structure is provided between the connecting rod and the lifting column to realize the lifting and lowering movement of the lifting column when the transmission gear rotates, and the lifting column can abut against the positioning plate frame and force the positioning plate frame to move upward.

[0020] By adopting the above-mentioned technical solution, during the thermal drying of the ceramic body, the drive motor is controlled to drive the driving gear, thereby causing the transmission gear to rotate about its own central axis. A spiral structure is used to transmit power between the connecting rod fixed to the transmission gear and the lifting column. This structure forces the lifting column to move toward or away from the positioning plate when the transmission gear rotates, thereby lifting the positioning plate upward, thereby achieving a linkage arrangement between the positioning plate and the lifting column. It can be seen that if the lifting column moves away from the positioning plate under the drive of the transmission gear, the positioning plate can remain against the lifting column under the action of its own weight and the weight of the counterweight, thus achieving a linkage arrangement between the positioning plate and the lifting column.

[0021] Optionally, the spiral structure includes a deflection guide column vertically fixed to the connecting rod and two spiral grooves opened on the inner peripheral wall of the lifting column tube, wherein each spiral groove is spirally extended along the axial direction of the lifting column tube, the two spiral grooves are arranged in parallel, and the axial spacing between the two is equal everywhere; ball heads are respectively provided at both ends of the deflection guide column, and the two ball heads are respectively located in the two spiral grooves.

[0022] By adopting the above-described technical solution, when the transmission gear rotates under the drive of the driving gear, the connecting rod and the deflection guide column rotate along with the transmission gear, thereby causing the ball head to move within the spiral groove. The cooperation between the ball head and the spiral groove enables the lifting column to be raised and lowered vertically within the construction chamber, thereby driving the positioning plate frame to move. It should be noted that by positioning the ball heads at each end of the deflection guide column in the two spiral grooves, respectively, the stability of the deflection guide column's movement within the spiral groove is improved.

[0023] Optionally, an arc groove is provided on the side of the workstation base, and the arc axis of the arc groove coincides with the central axis of the driving gear; a fixed guide column is provided on the side of the placement seat, and the fixed guide column is inserted into the arc groove and automatically slides in the arc groove;

[0024] A mating column is fixed on the side of the station base close to the heating unit, and a mating groove is opened on the inner wall of the drying station. In the working state, the station base is against the inner wall of the drying station, and the mating column is matched and inserted in the mating groove.

[0025] By adopting the above technical solution, when the ceramic body is placed on the placement unit and the driving component pulls the station base into the inner side of the equipment assembly to perform heat drying of the ceramic body, the station base will abut against the inner wall of the drying station. At this time, the plug-in column can be matched and inserted into the plug-in groove, thereby limiting the flipping of the placement seat. After the ceramic body is dried, the driving component pushes the placement unit to the outer edge of the equipment assembly. At this time, the driving component is in a power-off state. The operator can manually hold the placement seat and pull the placement seat outward. The placement seat can rotate around the central axis of the driving gear, and finally the top end of the placement seat is tilted and exposed to the equipment assembly; during the outward movement of the placement seat, the cooperation of the driving gear and the transmission gear can make the positioning plate frame move away from the inner bottom wall of the placement seat, and finally the top end of the cage member can move outward to be exposed to the placement seat, thereby facilitating the removal and replacement of the cage member, and the operation is more convenient.

[0026] Optionally, the heating unit includes a heating base coaxially arranged on the inner bottom wall of the equipment assembly and an electric heating component arranged inside the heating base, and the outer wall of the heating base is provided with a plurality of connecting grooves, each connecting groove is respectively connected to a corresponding drying station; the driving component is configured as a linear cylinder, and the blocking mechanism includes an arc-shaped baffle rotatably mounted on the heating base and a connecting plate fixedly sleeved on the piston rod of the driving component, and in the initial state, the arc-shaped baffle matches and blocks the connecting groove;

[0027] A movable column is eccentrically fixed to the bottom of the arc-shaped baffle, and the heating base is provided with a second waist hole for the movable column to pass through; the connecting plate is provided with a strip hole, the extension direction of the strip hole is perpendicular to the travel direction of the piston rod of the driving component, and the movable column matches and passes through the strip hole and is movably arranged in the strip hole.

[0028] By adopting the above-mentioned technical solution, the electric heating component can heat the air inside the heating base during operation. In the initial state, because the arc-shaped baffles of each set of isolation mechanisms are normally blocked in each connecting groove, the hot air inside the heating base will not directly enter the drying station. When the driving component pulls the station base inward, the inner side wall of the strip hole always abuts the movable column. The connecting plate can drive the movable column to move within the second waist hole, thereby causing the arc-shaped baffle to rotate and leave the connecting groove. At this time, the interior of the heating base can be connected to the drying station corresponding to the connecting groove, and the hot air inside the heating base can enter the drying station to smoothly heat and dry the ceramic blanks on the drying station.

[0029] Optionally, a telescopic plate group is provided on the side of the work station base close to the heating unit, and the telescopic plate group is used to normally close the bottom area between the work station base and the heating unit; wherein the telescopic plate group includes a fixed base plate fixed to the work station base and a movable plate slidably connected to the fixed base plate, and a repulsion structure is provided between the movable plate and the side wall of the work station base, for forcing the movable plate to normally move in a direction away from the work station base.

[0030] By adopting the above-mentioned technical solution, the movable plate can normally move away from the work station base under the action of the repulsive structure, so that the telescopic plate group is normally in the expanded state; based on this, no matter whether the placement unit is in the initial state or the working state, the telescopic plate group can close the bottom area between the work station base and the heating unit, thereby ensuring that the interior of the drying station remains in a relatively closed state, which is conducive to the normal progress of the drying operation.

[0031] Optionally, the cage body component includes a cylindrical frame and a plurality of partition plates spaced apart inside the cylindrical frame, with a accommodating chamber formed between adjacent partition plates; each accommodating chamber side wall is hinged with an arc-shaped mesh cover, and an insertion rod is inserted between the arc-shaped mesh cover and the cylindrical frame to achieve a detachable connection between the arc-shaped mesh cover and the cylindrical frame.

[0032] By adopting the above-mentioned technical solution, a plurality of accommodating chambers are formed inside the cage component by dividing the cage component by the partition mesh plate. By placing the ceramic blank on the partition mesh plate, rotating the arc-shaped mesh cover to close the accommodating chamber, and then inserting the rod member between the arc-shaped mesh cover and the cylindrical frame, the arc-shaped mesh cover can be quickly closed, thereby realizing the rapid placement of the ceramic blank, which has the advantage of easy operation.

[0033] Optionally, the equipment assembly includes a base, a main structure box fixed to the top surface of the base, and a sealing cover fixed to the top of the main structure box, and each drying station is evenly spaced on the outer peripheral surface of the main structure box; a plurality of independent cold air chambers are provided inside the main structure box, and each cold air chamber is alternately arranged with each drying station;

[0034] The inner bottom wall of each cold air chamber is equipped with a fan component, and the side wall of the cold air chamber close to the adjacent drying station is provided with ventilation holes. In the working state, the station base blocks the ventilation holes; in the initial state, the ventilation holes are directly connected to the area between the station base and the heating unit.

[0035] By adopting the above-mentioned technical solution, when the ceramic blank is being hot-dried, the workstation base can block the ventilation holes. At this time, the cold air generated by the fan component will not enter the drying station to affect the air temperature inside the drying station; when the drying operation is completed and the driving component pushes the workstation base to the outer edge of the equipment assembly, the ventilation holes can be directly opposite the area between the workstation base and the heating unit. At this time, the cold air generated by the fan component can enter the drying station, thereby cooling the drying station during the time interval waiting for the operator to pick up and unload the materials.

[0036] Optionally, the sealing cover is coaxially provided with a mounting port, and a porous filter plate is matched and installed in the mounting port; a plurality of air flow channels are provided on the side of the sealing cover close to the main structure box, and each air flow channel is connected to the mounting port; the number of the air flow channels matches that of the cold air chambers, and when the sealing cover is fixed to the main structure box, each air flow channel is directly connected to each cold air chamber.

[0037] By adopting the above-mentioned technical solution, a complete air supply path can be formed between the porous filter plate, the air path flow channel and the cold air chamber, and by arranging the air path flow channel on the bottom surface of the sealing cover, the mesh holes of the cold air chamber and the porous filter plate can be staggered with each other in the horizontal plane, thereby changing the direction of the air when flowing in the air supply path, which helps to achieve the effect of silencing and reducing noise.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. By placing the ceramic body in the accommodating chamber of the cage component, and positioning the cage component on the placement seat of one group of placement units, controlling the driving component to pull the workstation base of the placement unit inward, and opening the corresponding barrier mechanism, the ceramic body can be normally dried, and the drying operations of each group of placement units will not affect each other;

[0040] 2. By setting up multiple groups of placement units, each ceramic body produced by the front-end process can be dried continuously. The drying time of the ceramic bodies on each group of placement units is staggered, ensuring that there are always drying stations available for use, so that each ceramic body can be dried in real time. While ensuring that the equipment production capacity per unit time meets the standard, it can also reduce waiting time and help improve the overall production efficiency of the drying oven;

[0041] 3. By setting up a positioning plate frame, when the lifting column tube abuts against the positioning plate frame, the positioning plate frame can be forced to move in the vertical direction, thereby improving the heating uniformity of the ceramic embryo; and when the positioning plate frame moves upward until the plug-in column abuts against the top wall of the vertical slide groove, the plug-in column and the guide groove cooperate to make the positioning plate frame rotate around its own central axis, thereby being able to dry the ceramic embryo in all directions, which helps to further enhance the heating uniformity of the ceramic embryo.

DETAILED DESCRIPTION

[0054] The following is combined with Figure 1 -Attached Figure 9 This application is described in further detail.

[0055] The embodiments of the present application disclose a drying device for industrial ceramic production.

[0056] Reference Figure 1 A drying device for industrial ceramic production includes an equipment assembly 1, wherein the equipment assembly 1 comprises a base 11, a main structural box 12, and a sealing cover 13. The main structural box 12 is fixedly connected to the top of the base 11, and the sealing cover 13 is fixedly connected to the top of the main structural box 12. A plurality of drying stations 14 are provided on the outer circumference of the main structural box 12. In this embodiment, the number of drying stations 14 is set to 6, and each drying station 14 is equidistantly arranged around the central axis of the main structural box 12. It is understood that in other feasible embodiments, the specific number of drying stations 14 may also be 5, 7, or 8, and is not limited to the number provided in this embodiment.

[0057] Reference Figure 2 Each drying station 14 is provided with a placement unit 3 for placing ceramic blanks, and the main structural box 12 is provided with a heating unit 2 for thermally drying each group of placement units 3. The heating unit 2 includes a heating base 21 and an electric heating component 22. A fixed base 23 is coaxially provided at the bottom of the heating base 21, and the heating base 21 is fixed to the base 11 via the fixed base 23. The cross-section of the heating base 21 is polygonal, and the specific number of its sides is equal to the number of drying stations 14. The heating base 21 is matched and embedded in the main structural box 12, so that the corners of the heating base 21 can match and fit the inner wall of the main structural box 12, and the sides of the heating base 21 can respectively face each drying station 14. The electric heating component 22 is coaxially installed inside the heating base 21 and can heat the air inside the heating base 21 to increase its temperature.

[0058] Also refer to Figure 3The placement unit 3 includes a station base 4, a placement seat 5, a cage member 6 and a driving member 7, wherein the width of the station base 4 is equal to the width of the drying station 14, the station base 4 is slidably installed on the drying station 14, and the moving direction of the station base 4 is set in the same direction as the radial direction of the main structure box 12; the driving member 7 uses a linear cylinder, the driving member 7 is fixed to the fixed base 23, and the piston rod 71 of the driving member 7 is fixedly connected to the station base 4. By controlling the action of the driving member 7, the station base 4 can be forced to move in the drying station 14. It should be noted here that in the initial state, the station base 4 can stay at the outer edge of the main structure box 12, waiting for the ceramic blank that needs to be heat-dried.

[0059] The placement seat 5 is rotatably mounted on the inner side of the workstation base 4. A construction chamber 51 is provided on the side of the placement seat 5 close to the heating unit 2. The construction chamber 51 passes through the top surface of the placement seat 5. A handle 52 is provided on the side of the placement seat 5 away from the heating base 21. When loading, the placement seat 5 can be turned over to rotate it until part of it is exposed to the main structure box 12. Figure 3 , two opposite side surfaces of the placement seat 5 are fixedly connected with fixed guide pillars 53, and the number of fixed guide pillars 53 located on the same side is 2; two opposite inner side walls of the work station base 4 are respectively provided with arc grooves 41, and the number of arc grooves 41 located on the same side is two, the two arc grooves 41 are kept concentric, and the arc axis of the arc groove 41 is close to the bottom of the work station base 4; each fixed guide pillar 53 is inserted into the corresponding arc groove 41, and the fixed guide pillar 53 can slide along the arc direction of the arc groove 41.

[0060] Also refer to Figure 3 、 Figure 4 It should be noted here that a mating column 43 is fixed to the side of the work station base 4 close to the heating base 21, and a mating groove 15 is provided on the inner wall of the drying station 14. In the working state, that is, when the work station base 4 enters the inner side of the main structure box 12 and the ceramic blank is heat-dried, the work station base 4 can be abutted against the inner wall of the drying station 14, and the mating column 43 can be matched and inserted in the mating groove 15, thereby limiting the rotation of the work station base 4.

[0061] Reference Figure 5A gear transmission mechanism 8 is provided between the placement seat 5 and the workstation base 4, which can realize rotational positioning after the placement seat 5 is rotated, and then maintain the rotational position. Specifically, the gear transmission mechanism 8 includes a lifting column 81, a driving gear 82, a transmission gear 83 and a drive motor 84. The driving gear 82 is rotatably mounted inside the workstation base 4 and located below the placement seat 5. The central axis of the driving gear 82 coincides with the arc axis of the arc groove 41. The drive motor 84 is fixed to the workstation base 4, and the output shaft of the drive motor 84 is coaxially connected to the driving gear 82. By controlling the operation of the drive motor 84, the driving gear 82 can be rotated. The transmission gear 83 is rotatably mounted at the bottom of the placement seat 5, and the axial direction of the transmission gear 83 is perpendicular to the axial direction of the driving gear 82. The transmission gear 83 and the driving gear 82 are meshed and transmitted with each other.

[0062] Reference Figure 6 The outer circumference of the lifting column 81 is polygonal, specifically a quadrilateral in this embodiment; the lifting column 81 is movably inserted into the bottom wall of the construction chamber 51 and can be raised and lowered along the height direction of the construction chamber 51; a connecting rod 85 is coaxially fixed to the top of the transmission gear 83, and the connecting rod 85 extends into the interior of the lifting column 81. A spiral structure is provided between the connecting rod 85 and the lifting column 81, so that when the transmission gear 83 rotates, it can drive the lifting column 81 to move up and down. It can be understood here that in the initial state, by turning off the drive motor 84, the operator acts on the handle 52 to force the placement seat 5 to flip outward, so that the placement seat 5 and the lifting column 81 can rotate together around the central axis of the driving gear 82. At this time, the engagement between the transmission gear 83 and the driving gear 82 can keep the placement seat 5 in its rotational position.

[0063] Furthermore, the spiral structure includes a deflection guide post 851 vertically fixed to the connecting rod 85 and two spiral grooves 811 defined in the inner circumferential wall of the lifting column 81. Each spiral groove 811 extends helically along the axis of the lifting column 81. The two spiral grooves 811 are arranged side by side, and the axial spacing between the two spiral grooves 811 is equal at all locations. A ball head 852 is provided at each end of the deflection guide post 851. Each ball head 852 is integrally formed with the deflection guide post 851, and the two ball heads 852 are respectively located in the two spiral grooves 811. As can be seen, when the transmission gear 83 is driven to rotate, the ball heads 852 can move within the spiral grooves 811, thereby forcing the lifting column 81 to move up and down within the construction chamber 51.

[0064] A positioning plate frame 54 is slidably installed inside the construction chamber 51, and the positioning plate frame 54 is used to position and place the cage member 6; the positioning plate frame 54 is arranged opposite to the lifting column tube 81, so that the lifting column tube 81 can push the positioning plate frame 54 upward when it moves up and down in the construction chamber 51, thereby realizing the linkage setting between the positioning plate frame 54 and the gear transmission mechanism 8.

[0065] Specific reference Figure 7 , a number of extension columns 541 are vertically fixed to the bottom of the positioning plate frame 54, and the extension columns 541 are eccentrically arranged with the positioning plate frame 54; a first waist hole 511 is opened on the bottom wall of the construction chamber 51, and the arc axis of the first waist hole 511 coincides with the central axis of the positioning plate frame 54; the extension column 541 is passed through the first waist hole 511, and the axial length of the extension column 541 is greater than the hole depth of the first waist hole 511; based on this, the positioning plate frame 54 can move in the construction chamber 51 both along the height direction of the construction chamber 51 and along the arc direction of the first waist hole 511.

[0066] It should be noted that, in order to enhance the stability of the connection between the positioning plate frame 54 and the placement seat 5, in this embodiment, the number of extension columns 541 is set to two, and the number of first waist holes 511 formed in the placement seat 5 is also two. The two first waist holes 511 are located on the outer circumference of the lifting column tube 81. In addition, a counterweight portion 542 is fixed to the bottom of each extension column 541. The provision of the counterweight portion 542 is used to increase the overall weight of the positioning plate frame 54, so that the positioning plate frame 54 can remain tightly against the lifting column tube 81 under the action of gravity, or can keep the positioning plate frame 54 in normal contact with the bottom wall of the construction chamber 51.

[0067] Two opposite inner walls of the construction chamber 51 are respectively provided with vertical slide grooves 512, which extend along the height direction of the construction chamber 51, and a plug-in column 55 is installed inside each vertical slide groove 512, and the plug-in column 55 is freely slidable in the vertical slide groove 512; a guide groove 543 is provided on the outer peripheral surface of the positioning plate frame 54, and the guide groove 543 is bent and extended along the axial direction of the positioning plate frame 54, and each plug-in column 55 is normally inserted in the guide groove 543.

[0068] Back to Figure 6, multiple limiting columns 544 are vertically fixed to the top edge of the positioning plate frame 54, and all limiting columns 544 are equidistantly arranged around the central axis of the positioning plate frame 54; the cage component 6 includes a cylindrical frame 61, a supporting base plate 62 fixed to the bottom of the cylindrical frame 61, and multiple partition plates 63 arranged inside the cylindrical frame 61, and the outer peripheral surface of the supporting base plate 62 is equidistantly provided with multiple limiting grooves 621, and the number of limiting grooves 621 is equal to the number of limiting columns 544; by placing the supporting base plate 62 on the positioning plate frame 54, the various limiting columns 544 of the positioning plate frame 54 are respectively clamped in the various limiting grooves 621, so that the cage component 6 can be positioned and placed, and the cage component 6 can rotate with the positioning plate frame 54.

[0069] The partition plates 63 are arranged equidistantly on the inner side of the cylindrical frame 61, and a receiving chamber 66 for placing the ceramic blank can be formed between adjacent partition plates 63; the side wall of each receiving chamber 66 is opened, and the open side wall is hinged with an arc-shaped mesh cover 64, and an insertion rod 65 is inserted between the arc-shaped mesh cover 64 and the cylindrical space. The insertion rod 65 can realize a detachable connection between the arc-shaped mesh cover 64 and the cylindrical frame 61, and has the advantages of convenient connection and quick operation.

[0070] Reference Figure 6 、 Figure 7 During the drying process, after the cage member 6 containing the ceramic blank is positioned and placed on the positioning plate frame 54, the driving motor 84 is controlled to operate so that the driving gear 82 drives the transmission gear 83 to rotate. The connecting rod 85 and the deflection guide post 851 can rotate along with the transmission gear 83. Then, the movement of the ball head 852 in the spiral groove 811 can cause the lifting column 81 to move toward or away from the positioning plate frame 54. Ultimately, the lifting column 81 can lift the positioning plate frame 54 and move it upward, thereby improving the uniformity of heating of the ceramic blank. When the positioning plate frame 54 moves upward, it can move the plug-in column 55 along the vertical slide groove 512. When the plug-in column 55 moves upward to the limit position, the positioning plate frame 54 continues to move upward under the force. At this time, the plug-in column 55 and the guide groove 543 cooperate to cause the positioning plate frame 54 to rotate about its own central axis, thereby drying the ceramic blank in all directions, helping to further enhance the uniformity of heating of the ceramic blank and ensure the quality of the ceramic molding.

The drying station 14 and the heating unit 2 are in a partitioned state through the barrier mechanism 9, and the thermal drying of each group of placement units 3 can be independently controlled; each side of the heating base 21 is provided with a connecting groove 211, and the number of the connecting grooves 211 is equal to the number of the drying stations 14, and each connecting groove 211 is respectively connected to each drying station 14; each group of barrier mechanisms 9 is respectively provided at each connecting groove 211.

[0072] Reference Figure 8 The blocking mechanism 9 includes an arc-shaped baffle 91 and a connecting plate 92. An integrally formed turntable plate 911 is provided at the bottom of the arc-shaped baffle 91. The arc-shaped baffle 91 is rotatably mounted on the inner bottom wall of the heating base 21 via the turntable plate 911. In the initial state, the arc-shaped baffle 91 can be matched and blocked in the connecting groove 211. A movable column 912 is vertically fixed to the bottom of the turntable plate 911, and is eccentrically arranged between the movable column 912 and the turntable plate 911. The heating base 21 is provided with a second waist hole 212, the arc axis of the second waist hole 212 coincides with the rotation axis of the turntable plate 911. The movable column 912 is matched and penetrates the second waist hole 212, and the movable column 912 can slide freely in the second waist hole 212.

[0073] The connecting plate 92 is fixedly mounted on the outer peripheral side of the piston rod 71 of the driving member 7. The connecting plate 92 is provided with a through strip hole 921. The extension direction of the strip hole 921 is perpendicular to the travel direction of the piston rod 71 of the driving member 7. The movable column is matched and penetrates the strip hole 921 and can move freely in the strip hole 921. It should be noted that the arc baffle 91 can be blocked in the connecting groove 211 in the initial state. When the driving member 7 is actuated to pull the workstation base 4 inward, the side wall of the strip hole 921 can abut against the movable column and force the arc baffle 91 to rotate. Finally, the arc baffle 91 can be separated from the connecting groove 211, so that the heated air inside the heating base 21 can smoothly enter the drying station 14 to dry the ceramic blank.

[0074] In addition, a telescopic plate group 42 is provided on the side of each workstation base 4 close to the heating unit 2, wherein the telescopic plate group 42 includes a fixed base plate 421 and a movable plate 422, the fixed base plate 421 is vertically fixed to the workstation base 4, and the fixed base plate 421 is provided with two movable slots, and the extension direction of the movable slots is set in the same direction as the moving direction of the working base; two movable rods are fixed to the bottom of the movable plate 422, and the two movable rods are respectively passed through the two movable slots, and the movable rods can move freely in the movable slots.

[0075] A repulsion structure 423 is provided between the movable plate 422 and the fixed base. In this embodiment, the repulsion structure 423 includes a first magnet fixedly embedded in the fixed base and a second magnet fixedly embedded in the movable plate 422. The first magnet and the second magnet have the same magnetic properties and can always generate a magnetic force acting on the movable plate 422, thereby forcing the movable plate 422 to normally move away from the fixed base, so that the telescopic plate group 42 is normally in an extended state. It should be noted here that the movable plate 422 can always be in contact with the bottom surface of the heating base 21, and is used to normally close the bottom area between the workstation base 4 and the heating unit 2 to ensure the normal operation of the drying operation.

[0076] In addition, back to Figure 4 The main structure box 12 is further provided with a plurality of independent cold air chambers 121.

Figure 2 In the working state, the working base 4 can block the ventilation holes 123. When the ceramic body is dried and the working base 4 is restored to its initial position, the ventilation holes 123 can face the area between the working base 4 and the heating space, thereby cooling the ceramic body.

[0078] The implementation principle of a drying device for industrial ceramic production in the embodiment of the present application is as follows:

[0079] During the drying process of the ceramic embryo, each group of placement units 3 can independently carry out the drying operation of the ceramic embryo; during the drying process of the ceramic embryo, if a new ceramic embryo needs to be dried, the new ceramic embryo can be placed in the accommodating chamber 66 of the cage member 6, and the cage member 6 is positioned and placed in another group of placement units 3, so as to be sent into the interior of the equipment assembly 1 for heat drying. Based on this, the drying equipment can continuously dry each ceramic embryo produced by the front-end process, and the drying time of the ceramic embryos on each group of placement units 3 is staggered, which can ensure that there is always a drying station 14 in a usable state, so as to facilitate the real-time drying of each ceramic embryo, while ensuring that the equipment production capacity per unit time meets the standard, and can reduce waiting time, which helps to improve the overall production efficiency of the drying box.
