Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a recycling inorganic pigment freeze-drying equipment. Background Art

[0002] In the traditional drying process of inorganic pigments, high temperature may cause changes in crystal structure, color change, agglomeration and other problems. In order to maintain the high quality of pigments, meet the needs of the high-end market, comply with environmental protection requirements and adapt to the development trend of the industry, people use inorganic pigment freeze-drying equipment to dry inorganic pigments under low temperature and vacuum environment, avoiding problems such as changes in pigment crystal structure, color change and agglomeration caused by high temperature, and maintaining the key performance indicators of pigments such as color, particle size and dispersibility to the greatest extent. Inorganic pigment freeze-drying equipment includes refrigeration system, vacuum system, heating system, material holding system and control system.

[0003] However, in the subsequent collection process of inorganic pigments, it is necessary to wait for the drying chamber to slowly return to room temperature or near room temperature naturally. After a long wait, the dried pigment collection container is carefully taken out from the freeze dryer. During this period, the long cooling waiting time, slow manual operation and cumbersome steps have brought many impacts on the subsequent freeze drying of inorganic pigments. From the perspective of production efficiency, the cooling waiting makes the overall process time-consuming, and the efficiency of manual operation is limited due to the need for meticulousness, which slows down the connection of subsequent production processes and the overall operation efficiency; in terms of pigment quality, although waiting for temperature to return can reduce the risk of moisture, it is easy to increase the probability of contamination by impurities, and cumbersome manual operation is easy to affect the purity of the pigment due to mistakes; in terms of cost, time and labor costs will increase due to time-consuming operation, more manual input and professional training; for equipment maintenance, long waiting for temperature return may accelerate the aging of components, and cumbersome operation will lead to more impurities, which increases the difficulty and frequency of cleaning, and increases the cost of maintenance and cleaning. In short, these factors have brought complex and non-negligible impacts on the collection operation in many aspects. Summary of the invention

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example:

[0038] See also Figure 1-Figure 8 The present invention provides a technical solution for a recycled inorganic pigment freeze-drying device:

[0039] like Figure 1 As shown, the device includes a freeze-drying chamber 1, a supporting frame 2, a supporting member 3 and a motor 4. The freeze-drying chamber 1 is configured to be cylindrical, and the bottom end of the inner wall of the freeze-drying chamber 1 is rotatably connected to the bottom end of the supporting frame 2. The top of the freeze-drying chamber 1 is provided with a motor 4 that provides driving force for the rotation of the supporting frame 2, and the motor 4 rotates forward and reverse under the action of the supporting frame 2.

[0040] like Figure 1 and Figure 2As shown, the supporting frame 2 includes a positioning member 21 which is transmission-connected to the output end of the motor 4, a positioning frame 22 is symmetrically fixed on the outer surface of the circular axis of the positioning member 21, a stirring member 23 is arranged at the bottom end of the positioning member 21, a limiting member 24 is fixedly connected to the bottom end of the positioning frame 22, a supporting member 25 is fixedly connected to the bottom end of the limiting member 24, and the middle part of the bottom end of the supporting member 25 is connected to another positioning member 21.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, the inner walls of the three limit members 24 are all provided with rectangular grooves, which are symmetrically arranged. The inner walls of the rectangular grooves are slidably connected with a clamping block 28. The side of the clamping block 28 close to the center of the limit member 24 is set as a trapezoidal surface. The clamping block 28 can be clamped and fixed to the outer surface of the circumference of the carrier 3, as shown in FIG. Figure 3 As shown, the carrier 3 includes a tray 31, a positioning groove 32 and a limiting groove 33. The tray 31 can be placed inside the limiting member 24, and the height of the tray 31 is less than the height of the positioning frame 22. The staff can easily and quickly put the carrier 3 for carrying inorganic pigments into the corresponding position in the freeze-drying chamber 1. The side of the tray 31 is symmetrically provided with a positioning groove 32 for engaging and connecting the card block 28. The inner wall of the positioning groove 32 is symmetrically fixed with an arc bar, which can increase the friction between the engaged card block 28 and the tray 31. During the freeze-drying process, the carrier 3 is ensured to rotate synchronously with the limiting member 24, so as to avoid the relative lag in the starting rotation time of the carrier 3 as the driven component when the limiting member 24 rotates, so that the angle deviation between the two is generated, and the rotation action is difficult to accurately reproduce. At the same time, the additional vibration, impact and other unfavorable conditions caused by the rotation gap between the two are reduced, and the alternating stress borne by the components is reduced.

[0042] As 2 and Figure 4 As shown, the positioning member 21 includes a positioning block 211, the top of the uppermost positioning block 211 is drivingly connected to the output end of the motor 4, the outer circumferential surface of the positioning block 211 is fixedly connected to the frame plate 221 of the positioning frame 22, the frame plate 221 is set as an L-shaped plate, the bottom end of the frame plate 221 is fixedly connected to the upper surface of the uppermost limiting member 24, and the bottom end of the limiting member 24 is fixedly connected to the support member 25, refer to Figure 5The support member 25 includes a support frame 251 fixedly connected to the lower surface of the limiting member 24, the support frame 251 and the frame plate 221 are perpendicular to each other, the support frame 251 and the frame plate 221 form a cross frame, and provide all-round support to the bottom end of the tray 31, a second limiting member 24 is fixedly connected below the second positioning frame 22, a third positioning frame 22 and the support member 25 are fixedly connected below the second limiting member 24, and the support frame 251 and the frame plate 221 form a cross frame with each other, a third limiting member 24 is fixedly connected below the third positioning frame 22, and a cross-shaped support member 25 is fixedly connected below the third limiting member 24.

[0043] refer to Figure 2 , Figure 4 and Figure 6 The inner wall of the positioning block 211 is provided with a movable groove, a positioning shaft 213 is fixedly connected to the middle of the movable groove, a reciprocating screw rod 214 is fixedly connected to the lower end of the positioning shaft 213, the size of the movable groove is larger than the size of the positioning shaft 213, and an adjusting member 27 is arranged on the outer side of the top end of the positioning shaft 213, such as Figure 6 and Figure 8 The adjusting member 27 includes a symmetrically arranged limiting ring 271, which can form a closed circular ring. The bottom end of the limiting ring 271 is fixedly connected to a fixed block 1, and the inner wall of the fixed block 1 is rotatably connected to a connecting plate 272. The bottom end of the connecting plate 272 is rotatably connected to a fixed block 2, and the other end of the fixed block 2 is fixedly connected to a magnetic member 273. The magnetic member 273 is magnetically connected to the magnetic strip 233 of the stirring member 23. When the connecting plate 272 is in a vertical state, the distance between the limiting ring 271 and the magnetic member 273 is the largest, and at this time, the distance between the two limiting rings 271 is the smallest.

[0044] like Figure 4 As shown, the stirring member 23 includes a nut block 234 sleeved on the outside of the positioning shaft 213, a fixing ring 232 is fixedly connected to the bottom end of the nut block 234, the size of the fixing ring 232 is larger than the size of the nut block 234, the inner wall of the nut block 234 is provided with a threaded groove threadedly connected to the reciprocating screw 214, and a magnetic strip 233 magnetically connected to the magnetic member 273 is provided on the top of the fixing ring 232. A blade 231 is fixedly connected to the outer surface of the circumference of the fixing ring 232, and the blade 231 is arranged in an inclined shape, and the blade 231 is placed at a larger inclination angle relative to the rotation plane of the fixing ring 232. When the distance between the limiting ring 271 and the magnetic member 273 is the largest, the distance between the magnetic member 273 and the magnetic strip 233 is the shortest, so that the blade 231 is located at the upper end of the positioning shaft 213 and does not contact the reciprocating screw 214. The stirring member 23 will not contact the inorganic pigment in the freeze-drying process, and at this time, the limiting ring 271 is engaged with the outer surface of the nut block 234.

[0045] like Figure 2 , Figure 4 and Figure 8As shown, the positioning frame 22 also includes a frame plate 221 fixedly connected to the circumferential outer surface of the positioning member 21, a slide groove 222 is provided on the inner wall of the frame plate 221 in the transverse direction, a fixed plate 291 is slidably connected to the inner wall of the positioning frame 22, a fixed plate 292 is fixedly connected to the bottom end of the fixed plate 291, a slide groove 226 is provided on the inner wall of the frame plate 221 in the vertical direction, the fixed plate 292 is located on the inner wall of the slide groove 226, a cleaning plate 293 is fixedly connected to the outer side of the fixed plate 292, the fixed plate 1 291, the fixed plate 292 and the cleaning plate 293 can slide in the channel formed by the slide groove 1 222 and the slide groove 226, a side groove 223 is provided on the outer side of the slide groove 226, the cleaning plate 293 is slidably sealed on the inner wall of the side groove 223, and a groove 225 facilitating the sliding of the block 28 and a groove 1 224 facilitating the sliding of the fixed plate 1 291 are provided on the inner wall of the slide groove 226.

[0046] refer to Figure 2 , Figure 3 and Figure 5 The support member 25 also includes a hemispherical shaft 252 fixedly connected to the middle of the top of the support frame 251, and a limiting groove 33 is provided in the middle of the bottom of the tray 31. The hemispherical shaft 252 can be engaged with the inner wall of the limiting groove 33. Figure 7 and Figure 8 A cleaning strip 241 is fixedly connected to the outside of the limiting member 24, and the cleaning strip 241 can clean the inner wall of the freeze-drying bin 1 while rotating. A sliding cleaning plate 293 is provided in the space between the limiting members 24, which can clean the space between the limiting members 24 on the inner wall of the freeze-drying bin 1.

[0047] Before using the device, first place the carrier 3 in the space of the limiter 24. At this time, the freeze-drying chamber 1 is in an unpowered state, the electromagnetic structure at the top of the inner wall of the positioning block 211 is in the normal range of magnetic induction to the magnetic part 273, the stirring member 23 is in the middle position of the positioning shaft 213, and only the trapezoidal part of the cleaning strip 241 on the inner wall of the limiter 24 is exposed. When the carrier 3 is placed in, the cleaning strip 241 will limit the positioning groove 32 to a certain extent, and the hemispherical shaft 252 is engaged with the limiter groove 33 for limiting, but there is still a certain amount of movable space between the limiter 24 and the tray 31, which is convenient for the staff to adjust it. After the inorganic pigment mixture is introduced, the freeze-drying chamber 1 is closed and the freeze-drying process is started.

[0048] During the freeze-drying process, the motor 4 rotates clockwise. At this time, the electromagnetic structure at the top of the inner wall of the positioning block 211 increases the repulsive force on the magnetic member 273. The magnetic member 273 slides downward along the positioning shaft 213. The magnetic member 273 moves downward to move the inclined connecting plate 272 to a vertical state. The connecting plate 272 drives the limiting ring 271 to move toward the position of the positioning shaft 213. The movement of the limiting ring 271 drives the fixing plate 1 291 to move. The movement of the fixing plate 1 291 drives the fixing plate 292 to move. The movement of the fixing plate 292 drives the clamping block 28 to move toward the center of the limiting member 24, so that the clamping block 28 is completely engaged in the positioning groove 32 and is fixed through the fixing groove 32. The arc-shaped strip in the positioning groove 32 fills the gap therein, and the friction between the two is increased. When the motor 4 drives the positioning block 211 to rotate, the rotation of the positioning block 211 drives the positioning frame 22 to rotate, and the rotation of the positioning frame 22 drives the limit member 24 to rotate, and the rotation of the limit member 24 drives the support member 25 to rotate synchronously. The rotation of the limit member 24 drives the bearing member 3 fixedly connected thereto to rotate. The centrifugal force of the rotation makes the inorganic pigments in the freeze-drying process evenly distributed, and the inorganic pigment solids that are frozen first are first dispersed to the outer area of ​​the inner wall of the tray 31, and will not be frozen on the surface to interfere with the freeze-drying of the inorganic pigments in the lower layer, thereby improving the uniformity of the freeze-drying of the device and the quality of the finished product.

[0049] After freeze drying is completed, the temperature recovery process begins. At this time, the motor 4 rotates counterclockwise. At this time, the electromagnetic structure at the top of the inner wall of the positioning block 211 increases the attraction of the magnetic part 273. The magnetic part 273 slides upward along the positioning shaft 213. The upward movement of the magnetic part 273 causes the vertical connecting plate 272 to tilt and push the limiting ring 271 to a position away from the positioning shaft 213. The limiting ring 271 moves to drive the fixed plate 291 to slide on the inner side of the slide groove 222. The fixed plate 291 drives the fixed plate The second plate 292 slides on the inner wall of the second slide groove 226, the second fixing plate 292 moves in the direction away from the center of the limiting member 24, the movement of the first fixing plate 291 drives the block 28 to move, the block 28 moves and no longer engages and positions the positioning groove 32, the limiting groove 33 at the bottom of the tray 31 engages with the hemispherical shaft 252, the tray 31 can rotate around the hemispherical shaft 252, when the motor 4 drives the positioning frame 22 and the limiting member 24 to rotate counterclockwise, the bearing member 3 no longer rotates synchronously with the limiting member 24;

[0050] The magnetic piece 273 moves upward and gradually moves away from the magnetic strip 233. The magnetic strip 233 is no longer attracted by the magnetic piece 273, and the limiting ring 271 no longer positions the nut block 234. The stirring piece 23 slides along the positioning shaft 213 under the action of gravity until the nut block 234 is threadedly connected with the reciprocating screw rod 214. As the positioning shaft 213 rotates, the nut block 234 moves downward and rotates at the same time. The nut block 234 drives the fixing ring 232 to move downward, and the fixing ring 232 drives the blade 231 to move downward until it fits the inorganic pigment in the carrier 3. As the nut block 234 rotates, the blade 231 slightly stirs the freeze-dried inorganic pigment in the carrier 3, so that the pigment particles constantly change their contact positions with the air, the container wall and each other, thereby increasing the contact area between the pigment and the external ambient air, the container wall, etc., so that heat can be more efficiently transferred to each part of the pigment, so that it can receive heat more evenly, thereby accelerating the temperature recovery speed.

[0051] While the pigment is being stirred, the fixed plate 292 drives the cleaning plate 293 to move away from the center of the limiting member 24, so that the cleaning plate 293 fits against the inner wall of the freeze-drying chamber 1, and the cleaning strip 241 on the outer wall of the limiting member 24 cleans the inner wall of the freeze-drying chamber 1 in contact therewith. During the warming process, the space between each limiting member 24 on the inner wall of the freeze-drying chamber 1 is cleaned by the extended cleaning plate 293, and the flying pigment can be cleaned during the warming process, thereby improving the practicality of the device.
