Description

Technical Field

[0001] This invention relates to the field of pigment processing equipment technology, specifically to a raw material cooling device for processing organic pigments. Background Technology

[0002] The production process of organic pigments typically includes three main stages: raw material synthesis, pigmentation treatment, and post-processing. The processing steps include physical treatments such as filtration, washing, drying, crushing, and cooling. The drying process must avoid high temperatures that could cause pigment discoloration or decomposition. Subsequently, agglomerated pigments need to be broken up to improve subsequent dispersion efficiency. In traditional production, the high-temperature dried pigment cakes or blocks need to be cooled naturally or by simple air cooling. Because they agglomerate after extrusion and dehydration, the internal moisture does not disappear quickly. Therefore, after heating, as the moisture escapes, the agglomerates easily come into contact with the outside and agglomerates due to the long heating time, which increases the load on the subsequent crushing process. At the same time, cooling and crushing are carried out in separate steps, which is cumbersome and restricts production efficiency. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problems of slow cooling and cumbersome procedures in existing cooling devices, and to provide a raw material cooling device for organic pigment processing.

[0008] Preferably, the discharge structure includes a base, a pair of tilting frames, a first tilting seat, a second electric slide rail, a support arm, and a second tilting seat. The base is located below the main body box. The pair of tilting frames are symmetrically arranged in the middle of the upper wall of the base. The first tilting seat is a portal frame structure. The two ends of the first tilting seat are respectively movably arranged between the tilting frames, and the first tilting seat can be tilted left and right. The first tilting seat is fixedly connected to the middle of the lower wall of the main body box. The second electric slide rail is fixedly arranged on the upper wall of the base and passes through the tilting frames. One end of the support arm is tilted to the left and movably connected to the second electric slide rail. The support arm can move left and right through the second electric slide rail and can be tilted under force. The second tilting seat is movably arranged on the other end of the support arm and is fixedly connected to the lower right wall of the main body box. The second tilting seat is located to the left of the discharge port on the right side of the main body box.

[0009] Preferably, the crushing structure includes a crankshaft assembly, a motor, a limiting frame, a pair of impact rods, a pair of crushing seats, a pair of reciprocating arms, and a pair of connecting rods; the crankshaft assembly has two ends that movably penetrate the rear side wall and the front plate of the main body box, and is located between two baffles inside the main body box. The crankshaft assembly is located above the moving groove and below the cooling fan. The motor is fixedly installed on the rear side of the main body box, and the motor drive end is connected to one end of the crankshaft assembly. One end of the limiting frame is fixedly installed on the rear side wall inside the main body box, and is located below the crankshaft assembly.

[0014] The raw material cooling device for organic pigment processing proposed in this invention has the following advantages:

[0015] 1. By controlling the left and right tilt of the main structure through the discharge structure, bidirectional unloading can be achieved from both ends of the discharge port. Furthermore, by utilizing the density difference (or the same density) of the filter screens at both ends, pigment powders of different particle sizes can be filtered in a targeted manner to meet diverse screening needs and improve the flexibility and functionality of unloading.

[0016] 2. The baffle unit can centrally gather the blocky pigments, and the left and right tilting of the main structure causes the pigments to sway and shift, ensuring that the reciprocating lifting and lowering of the crushing structure allows the crushing seat to fully contact the material, efficiently impacting and breaking up the high-temperature pigment blocks. This design allows the pigments to be crushed simultaneously during the cooling stage, avoiding the extra step of "cooling and then transferring to the crushing equipment" in the traditional process, shortening the production cycle, reducing equipment investment costs, and simultaneously accelerating heat dissipation and improving the cooling effect. The crushed pigment particles are smaller and have a larger surface area, which, combined with the blowing action of the cooling fan, can significantly improve heat exchange efficiency and accelerate the heat dissipation of high-temperature pigments.

[0017] 3. The equipment integrates pigment collection, dispersion, heat dissipation, sieving, and bidirectional unloading functions, forming a continuous process. No manual intervention is required for material transfer between stages, reducing labor costs and material loss. At the same time, it reduces the risk of contamination caused by multiple transfers, improving overall production efficiency and product purity.

[0018] 4. The design of the material blocking unit's movement method (tilting or horizontal movement) and the removable and replaceable filter screen enables the equipment to adapt to the processing needs of pigments in different states (blocks, granules), taking into account both ease of operation and scene adaptability, thus enhancing the practical value of the equipment.

[0028] The following is in conjunction with the appendix Figures 1-8 A detailed description of specific embodiments of the present invention will be provided.

[0029] This invention provides a technical solution: a raw material cooling device for organic pigment processing, comprising a main structure 1, an outlet structure 2 provided on the lower wall of the main structure 1, and the main structure 1 being able to flip left and right on the outlet structure 2; a crushing structure 3 is fixedly provided in the middle of the main structure 1; wherein the main structure 1 is used to carry the dried pigment and dissipate heat and cool it, and the crushing structure 3 is used to break up the dried high-temperature pigment cake or block to improve heat dissipation efficiency and reduce subsequent processes; by controlling the left and right flipping of the main structure 1 through the outlet structure 2, the pigment powder can be discharged in both directions, and the particle size screening of the discharge at both ends can be achieved as needed.

[0030] As a further embodiment of the present invention, the main structure 1 includes a main body box 11, a front panel 12, three cooling fans 13, a pair of filters 14, a pair of electric push rods 15, and a baffle unit 16; the main body box 11 is a rectangular box without a front side wall, and discharge ports 5 are opened at the middle of the left and right ends of the lower wall of the main body box 11, and a feed port 4 is opened at the middle of the upper left side wall of the main body box 11. A linkage port 7 is opened on the upper wall of the main body box 11 near the rear end, and a movable groove 6 in the shape of an isosceles trapezoid is opened on the inner rear side wall of the main body box 11. The bottom length of the movable groove 6 is less than the top length, and the width at the connection between the top and the two ends of the movable groove 6 is relatively large. The front panel 12 is detachably fastened to the front of the main body box 11. On the side, the rear side wall of the front plate 12 has a movable groove 6 identical to that of the main body box 11. A pair of filter screens 14 are detachably installed on the lower walls at both ends of the main body box 11 and located at the discharge port 5. The density of the pair of filter screens 14 may be the same or different. One end of a pair of electric push rods 15 is fixedly inserted through the left and right side walls of the main body box 11 and is symmetrical to each other. The baffle unit 16 is fixedly installed on the main body box 11. The cooling is achieved by blowing air downwards through the cooling fan 13. The powder after being discharged and cooled is filtered in both directions through the filter screens 14. The baffle plate 163 in the baffle unit 16 is limited by the electric push rods 15, so as to realize the change of the movement mode of the baffle plate 163.

[0031] More specifically, when the main structure 1 tilts left and right through the outlet structure 2, the cooled pigment powder is discharged through the discharge ports 5 at both ends and filtered by the filter screen 14 at the corresponding positions. Since the density of the filter screen 14 can be set to different (e.g., the left end is a coarse filter screen and the right end is a fine filter screen), pigment powder of different particle sizes can be separated and discharged. If the density of the filter screen 14 is the same, equal bidirectional discharge can be achieved to meet different production needs.

[0032] As a further embodiment of the present invention, the baffle unit 16 includes a pair of first electric slide rails 161, a pair of force rods 162, a pair of baffle plates 163, and several pins 164; the pair of first electric slide rails 161 are symmetrically arranged on the upper wall of the main body box 11 and located behind the linkage port 7; one end of each pair of force rods 162 is connected to the first electric slide rails 161, and the other end of each force rod 162 moves through the linkage port 7; the force rods 162 move along the linkage port 7 via the first electric slide rails 161; the pair of baffle plates 163 are symmetrically embedded in the main body box 11, and the two ends of the baffle plates 163 are respectively inclined in opposite directions; the two ends of the pair of baffle plates 163 correspond to the upper and lower ends of the moving groove 6, respectively; the pair of baffle plates 163... One end of 63 is movably connected to the force-applying rod 162, and the connecting end is close to the lower wall of the main body box 11. Several pins 164 are symmetrically arranged at the four corners of the front and rear side walls of the baffle plate 163, and the pins 164 are movably inserted into the moving groove 6. The force-applying rod 162 is moved by the first electric slide rail 161, which in turn drives the baffle plate 163, which is movably connected to the force-applying rod 162, to move in the moving groove 6 by means of the pins 164. The baffle plate 163 can be tilted and moved along the moving groove 6 by the force-applying rod 162. When the baffle plate 163 is tilted, the top of the baffle plate 163 can be located on the left side of the feed inlet 4. The baffle plate 163 can be horizontally attached to the lower inner wall of the main body box 11 and can move left and right.

[0033] More specifically, the baffle unit 16 achieves the attitude adjustment (tilt or horizontal) and position movement of the baffle plate 163 through the drive of the first electric slide rail 161 and the guiding constraint of the moving groove 6, specifically divided into the following two core working states.

[0034] Inclined Convergence State: When the equipment is in the material crushing and cooling stage, the baffle plate 163 maintains an inclined posture, and its operation process is as follows: The first electric slide rail 161 drives the force rod 162 to move along the linkage port 7 towards the middle of the main body box 11, and the force rod 162 drives the baffle plate 163 to move synchronously; the pins 164 at the four corners of the baffle plate 163 slide along the inclined section of the isosceles trapezoidal moving groove 6. Since the bottom length of the moving groove 6 is less than the top length, and the width of the connection between the top and both ends is large, providing sufficient space for the pins 164 to move, the baffle plate 163 maintains an inverted state at both ends; at this time, the top of the baffle plate 163 can move to the left side of the feed inlet 4 to form a "funnel-shaped" convergence area, which guides the high-temperature pigment block (cake) fed from the feed inlet 4 to the middle of the main body box 11, ensuring that the crushing seat 35 of the crushing structure 3 can accurately act on the material and improve the crushing efficiency.

[0035] Horizontal flow guiding state: When the material has been crushed and cooled and needs to be unloaded, the baffle plate 163 switches to the horizontal state. The operation process is as follows: The first electric slide rail 161 drives the force rod 162 to move in the opposite direction to both ends of the main body box 11, which drives the baffle plate 163 to move to both ends of the moving groove 6; the pin shaft 164 slides to the horizontal section or turning part of the moving groove 6, and the baffle plate 163 gradually transitions from the inclined state to the horizontal state, and finally fits against the lower inner wall of the main body box 11; the horizontal baffle plate 163 can slide left and right along the lower inner wall of the main body box 11 as the force rod 162 continues to move, and cooperates with the left and right flipping of the main structure 1 (driven by the guide structure 2) to guide the crushed pigment powder to the corresponding discharge port 5 to realize unloading and flow guiding.

[0036] As a further embodiment of the present invention, the derived structure 2 includes a base 21, a pair of flipping frames 22, a first flipping seat 23, a second electric slide rail 24, a support arm 25, and a second flipping seat 26. The base 21 is located below the main body box 11. The pair of flipping frames 22 are symmetrically arranged in the middle of the upper wall of the base 21. The first flipping seat 23 is a portal frame structure, with its two ends movably disposed between the flipping frames 22, and the first flipping seat 23 can be flipped left and right. The first flipping seat 23 is fixedly connected to the middle of the lower wall of the main body box 11. The second electric slide rail 24 is fixedly disposed on the upper wall of the base 21. Through the rotating frame 22, one end of the support arm 25 is tilted to the left and movably connected to the second electric slide rail 24. The support arm 25 can move left and right through the second electric slide rail 24 and can be rotated under force. The second rotating seat 26 is movably set on the other end of the support arm 25 and is fixedly connected to the lower right wall of the main body box 11. The second rotating seat 26 is located to the left of the discharge port 5 on the right side of the main body box 11. The support arm 25 is moved by the second electric slide rail 24 on the base 21, which causes the support arm 25 to be rotated by force, thereby rotating the main body box 11 with the help of the first rotating seat 23 and the second rotating seat 26 to unload the powder.

[0037] More specifically, the output structure 2, through the linear drive of the second electric slide rail 24 and the lever action of the support arm 25, drives the main box 11 to tilt left and right around the first flip seat 23 as the axis, specifically divided into the following two unloading scenarios;

[0038] Material is discharged from the left outlet 5 (in conjunction with the left filter screen 14). When it is necessary to discharge material from the left outlet 5 of the main body box 11, the operation process is as follows: The second electric slide rail 24 drives the support arm 25 to move to the right; Since the support arm 25 is initially tilted to the left, its top end is constrained by the second flip seat 26 during the right movement, forcing the support arm 25 to flip upward around the bottom hinge, and the tilt angle gradually increases; The top end of the support arm 25 applies an upward thrust to the right end of the main body box 11 through the second flip seat 26, causing the main body box 11 to tilt to the left with the rotation axis of the first flip seat 23 as the center (at this time, the left end of the main body box 11 is lowered and the right end is raised); The pigment powder in the main body box 11 slides to the left under the action of gravity, and is filtered by the left filter screen 14 when it passes through the left outlet 5, completing the discharge of specific particle size.

[0039] The discharge port 5 on the right side cooperates with the filter screen 14 on the right side: When it is necessary to discharge from the discharge port 5 on the right side of the main body box 11, the operation process is as follows: The second electric slide rail 24 drives the support arm 25 to move to the left; During the leftward movement, the support arm 25 flips downward around the bottom hinge, and the tilt angle gradually decreases. Its top end applies a downward pulling force to the right end of the main body box 11 through the second flip seat 26; The main body box 11 tilts to the right with the rotation axis of the first flip seat 23 as the center (at this time, the right end of the main body box 11 is lowered and the left end is raised); The pigment powder in the main body box 11 slides to the right under the action of gravity, and is filtered by the filter screen 14 on the right side when it passes through the discharge port 5 on the right side, so as to achieve discharge of different or the same specifications as the particles on the left side.

[0040] After unloading is completed, the second electric slide rail 24 drives the slider back to the initial position, the support arm 25 returns to the initial angle of tilting to the left, and the main body box 11 returns to the horizontal state under the balance of gravity and the support arm 25, waiting for the next processing cycle.

[0041] As a further embodiment of the present invention, the crushing structure 3 includes a crankshaft assembly 31, a motor 32, a limiting frame 33, a pair of impact rods 34, a pair of crushing seats 35, a pair of reciprocating arms 36, and a pair of connecting rods 37. The crankshaft assembly 31 has two ends that movably penetrate the rear sidewall of the main body housing 11 and the front plate 12, respectively. The crankshaft assembly 31 is located between two baffle plates 163 inside the main body housing 11, above the moving groove 6, and below the cooling fan 13. The motor 32 is fixedly installed on the rear side of the main body housing 11, and the drive end of the motor 32 is connected to one end of the crankshaft assembly 31. One end of the limiting frame 33 is fixedly installed on the rear sidewall inside the main body housing 11, and the limiting frame 33 is located below the crankshaft assembly 31. One end of the impact rod 34 is movably inserted through the limiting frame 33. A pair of crushing seats 35 are fixedly mounted on the impact rod 34, and the crushing seats 35 can fit against the lower inner wall of the main body box 11. One end of a pair of reciprocating arms 36 is movably connected to the crankshaft assembly 31 and can rotate symmetrically. One end of a pair of connecting rods 37 is movably connected to the top of the impact rod 34, and the other end of the connecting rods 37 is movably connected to the reciprocating arms 36. The crankshaft assembly 31 is driven to rotate by the motor 32, and the reciprocating arms 36 are driven to swing back and forth by the crankshaft assembly 31, thereby driving the impact rod 34 to rise and fall back and forth, so as to achieve the lifting and lowering of the crushing seats 35 and crushing the pigment blocks. The rotation of the crankshaft assembly 31 can drive the impact rod 34 to move up and down.

[0042] The crushing structure 3 converts the rotational motion of the crankshaft assembly 31 into the reciprocating lifting motion of the impact rod 34, thereby achieving continuous crushing of the pigment block. The specific process is as follows:

[0043] After the motor 32 starts, it drives the crankshaft assembly 31 to rotate around its own axis. Due to the eccentric design of the shaft section of the crankshaft assembly 31, when it rotates, it will drive one end of the reciprocating arm 36 sleeved on the eccentric shaft section to make a circular motion. When the reciprocating arm 36 rotates with the crankshaft assembly 31, its end swings symmetrically back and forth around the hinge connection point (when the left reciprocating arm 36 swings to the left, the right reciprocating arm 36 swings to the right, and vice versa).

[0044] The swing of the reciprocating arm 36 is transmitted to the top of the impact rod 34 through the connecting rod 37. Due to the constraint of the guide hole of the limit frame 33, the impact rod 34 cannot make horizontal displacement. Therefore, the swing motion is converted into up-and-down reciprocating motion along the guide hole. When the reciprocating arm 36 swings upward, it pulls the impact rod 34 up through the connecting rod 37. When the reciprocating arm 36 swings downward, it pushes the impact rod 34 down.

[0045] The impact rod 34 drives the crushing seat 35 to move up and down synchronously. When it descends, the bottom surface of the crushing seat 35 is in contact with the lower inner wall of the main body box 11, impacting, squeezing and crushing the high-temperature pigment block (cake) gathered in the middle, breaking it into fine particles. When it rises, it separates from the bottom surface, providing space for the flow and heat dissipation of pigment particles. Then it descends again for the next round of crushing, forming a continuous operation cycle.

[0046] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0047] In this solution, the equipment is placed horizontally on the ground via base 21, supporting the main structure 1 at a certain height.

[0048] Material Input and Convergence: The dried, high-temperature pigment blocks (cakes) are input through the feed inlet 4 at the left end of the main body box 11. At this time, the baffle plate 163 of the baffle unit 16 is in an inclined state. That is, the force rod 162 is driven by the first electric slide rail 161. The force rod 162 moves the baffle plate 163 towards both ends of the main body box 11 along the linkage port 7. This causes the pin 164 at one end of the baffle plate 163 to tilt and flip along the middle of the moving groove 6. This allows the pigment to enter and then converge towards the middle of the main body box 11 through the guide of the baffle plate 163, and be located between the two baffle plates 163. Because the width of the connection between the upper and lower ends of the moving groove 6 and the middle part increases, the inclined baffle plate 163 cannot be driven by the first electric slide rail 161 to maintain the inclined relative movement; by extending the electric push rod 15, a limiting force is applied to the baffle plate 163, causing the pin 164 at the higher end of the inclined baffle plate to stably maintain the inclined angle, and cooperate with the first electric slide rail 161 from the middle of the moving groove 6, driving the pigment block (cake) into the top of the moving groove 6, thereby making the baffle plate 163 in an inclined state and moving in the center with the drive of the first electric slide rail 161 to gather the pigment;

[0049] Simultaneous crushing and heat dissipation: The motor 32 is started, which drives the crankshaft assembly 31 between the front plate 12 and the rear side wall of the main body box 11 to rotate. Through the movable connection of the reciprocating arm 36 and the connecting rod 37, reciprocating movement is formed. The impact rod 34 is pulled and moved up and down by the limit frame 33. The crushing seat 35 continuously impacts and crushes the gathered pigment blocks, breaking them into fine particles. At the same time, the three cooling fans 13 start synchronously and blow air downward to accelerate the heat dissipation of pigment particles. While increasing the heat dissipation area, forced convection cooling is achieved. The air dissipated is discharged from the filter screen 14 of the feed port 4 or the discharge port 5.

[0050] Screening and unloading preparation: Depending on the particle size to be screened, select to install filter screens 14 of different densities at the left and right discharge ports 5, such as a coarse filter screen on the left and a fine filter screen on the right, or set filter screens 14 of the same density at both ends as required. Select the unloading direction according to the orientation of the plant. Before unloading, the two first electric slide rails 161 drive the corresponding force rods 162 to move in the opposite direction, driving the baffle plate 163 from the inclined state to the two ends of the moving trough 6. Then, control the force rods 162 to move relative to each other again, transitioning the inclined baffle plate 163 to the horizontal state and adhering to the lower inner wall of the main body box 11. The corresponding baffle plate 163 can also be controlled according to the unloading direction to prepare for material flow.

[0051] For example, unloading from the left: the second electric slide rail 24 drives the support arm 25 to move to the right. As the support arm 25 moves to the right, the main body box 11 cannot move laterally due to the limitation of the first tilting frame 22. This causes the tilted support arm 25 to be tilted at both ends by the force on the second electric slide rail 24 and the second tilting seat 26. As the support arm 25 tilts, the right end of the main body box 11 is raised, while the left end of the main body box 11 is lowered. Then, with the blowing of the cooling fan 13 and the action of gravity, it tilts to the left, so that the crushed pigment passes through the horizontal baffle 163 and enters the left end of the main body box 11. It then passes through the discharge port 5 with the help of the filter screen 14 at the left end to complete the unloading.

[0052] Equipment reset and cycle: After unloading, the second electric slide rail 24 drives the slider back to the initial position, and the main body box 11 returns to the horizontal state; the first electric slide rail 161 drives the baffle plate 163 to move to the left end of the main body box 11. With the guidance of the inclined moving groove 6, the baffle plate 163 is tilted again, and the electric push rod 15 can be extended to apply force to put the pin 164 at the top of the baffle plate 163 into the top of the moving groove 6 and into a horizontal state, ready for the next round of material input and processing.
