Description

Technical Field

[0001] The present invention relates to the technical field of dryers, and specifically to a flipping and vibrating drying device. Background Art

[0002] In the fields of chemical industry, food, and pharmaceuticals, the rapid and uniform drying of materials is a key link in the production process. Traditional drying devices mostly adopt hot air convection or static heating methods, which have problems such as uneven heating of materials and incomplete drying in the central area. Especially when dealing with easily sticky granular materials (such as chemical masterbatches), caking often occurs due to local moisture residues, and an additional crushing process needs to be added, significantly increasing energy consumption and time costs. In addition, conventional vibrating drying equipment mostly relies on an independent drive system to control the flipping and vibrating actions separately, resulting in a complex structure, poor operating stability, and high maintenance costs. Therefore, there is an urgent need for a drying device that integrates vibration, flipping, and intelligent moisture removal functions to simplify the operation process, improve drying uniformity, and reduce energy consumption to meet the requirements of continuous production.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a flipping and vibrating drying device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a flipping and vibrating drying device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A flipping and vibrating drying device, including a base, a drying box assembly, and a heating assembly. A support assembly is arranged at the outer end of the top of the base, and a motor is arranged at the outer end of the top of the base. The output end of the motor is provided with a drying box assembly. The drying box assembly includes a box body, a fixed ring seat, a first support rod, an exhaust groove, a second support rod, a sliding block, a tension spring, a connecting seat, a counterweight, an air inlet groove, a ventilation groove, an electromagnet, a bearing seat, and a feeding port. Fixed ring seats are arranged at both ends of the outside of the box body. A first support rod is arranged at the outer end of the top of the fixed ring seat, and an exhaust groove is opened inside the first support rod. A second support rod is arranged at the outer end of the bottom of the fixed ring seat. The outer ends of the first support rod and the second support rod are connected with a sliding block. A tension spring is arranged inside the first support rod, and a connecting seat is arranged at the bottom end of the tension spring. A counterweight is arranged at the outer end of the bottom of the connecting seat, and an air inlet groove is opened inside the counterweight. A ventilation groove is opened inside the connecting seat. An electromagnet is arranged at the inner side of the bottom of the box body, and a bearing seat is arranged at the inner side of the right part of the box body. A feeding port is arranged at the top of the box body.

[0006] Further, the support assembly includes a support member, a positioning ring seat, a material passing groove, and a sliding groove. A positioning ring seat is arranged at the outer end of the support member, and material passing grooves are formed on both the upper and lower sides of the positioning ring seat. A sliding groove is formed inside the positioning ring seat.

[0007] Further, the motor and the box body are eccentrically distributed, and the motor and the positioning ring seat are concentrically distributed.

[0008] Further, the sliding block is integrally structured with the first support rod and the second support rod, and the sliding block slides inside the sliding groove.

[0009] Further, the connection seat and the counterweight are integrally structured, and the connection seat is elastically connected to the first support rod through a tension spring.

[0010] Further, the air inlet groove is communicated with the air ventilation groove, and the displacement of the connection seat causes the air ventilation groove to be communicated with the air exhaust groove.

[0011] Further, the bottom contour of the counterweight matches the inner contour shape of the box body, and the downward movement of the counterweight exposes the air inlet groove.

[0012] Further, a heating assembly is arranged at the right end of the top of the base. The heating assembly includes a hot air blower, a connecting pipe, a ventilation duct, an air outlet, a return spring, and an armature pressing block. A connecting pipe is connected to the outer end of the hot air blower, and a ventilation duct is formed inside the connecting pipe. An air outlet is formed at the outer end of the connecting pipe. A return spring is arranged inside the bottom of the connecting pipe, and an armature pressing block is arranged at the outer end of the return spring.

[0013] Further, the hot air blower is communicated with the air outlet through the ventilation duct, and the connecting pipe is concentrically distributed with the positioning ring seat and the motor.

[0014] Further, the return spring is elastically connected to the armature pressing block, and the armature pressing block is electromagnetically adsorbed and connected to the electromagnet.

[0015] The present invention provides a flipping and vibrating drying device, which has the following beneficial effects: 1. In the present invention, the motor drives the drying box assembly to perform eccentric rotation around the bearing seat through the output end. At the same time, the hot air blower conveys hot air to the ventilation duct through the connecting pipe, and the hot air is evenly blown onto the surface of the chemical masterbatch in the box body through the air outlet to accelerate drying. The eccentric rotation enables the box body to simultaneously realize material flipping and periodic vibration during rotation, which not only avoids the problem of incomplete drying of the central material, but also improves the drying uniformity through the synergistic effect of flipping and vibration. This design integrates the flipping and vibration functions of the material into a single rotation action, simplifies the equipment operation logic, and significantly reduces the operation and maintenance difficulty.

[0016] 2. During the rotation of the box body of the present invention, the sliding block slides along the sliding groove to enhance the stability of eccentric rotation. The tension spring and the counterweight form an elastic system. When the box body rotates to the top, the counterweight moves downward due to inertia, and the tension spring generates a reverse pulling force. Combining with the limit control of the positioning ring seat to control the vibration amplitude, ensuring stable operation. When the counterweight moves downward, the air inlet groove inside it is exposed, and the displacement of the connection seat makes the exhaust groove communicate with the ventilation groove, and the water vapor generated by drying is discharged through this path. This exhaust mechanism is triggered only when the counterweight moves downward, which not only reduces the heat loss inside the box body but also avoids the retention of water vapor affecting the drying efficiency, realizing the dynamic balance of heat dissipation and moisture removal.

[0017] 3. During the drying process of the present invention, after the electromagnet inside the box body is turned on, based on the eccentric distribution of the box body and the connecting pipe, when the electromagnet approaches the connecting pipe, it adsorbs the armature pressing block, stretches the return spring and makes it move out of the connecting pipe, and then presses the chemical masterbatch at the bottom of the box body. This action can immediately disperse the masterbatch agglomerated due to water evaporation, avoiding the subsequent separate crushing process. At the same time, by using the characteristic of the volume difference of the materials, the drying uniformity is improved through external force dispersion, effectively solving the problem of insufficient local drying caused by agglomeration.

Detailed implementation mode

[0020] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a flipping and vibrating drying device, including a base 1, a drying box assembly 4 and a heating assembly 5. A support assembly 2 is arranged at the outer end of the top of the base 1, and a motor 3 is arranged at the outer end of the top of the base 1. The output end of the motor 3 is provided with a drying box assembly 4. The drying box assembly 4 includes a box body 401, a fixed ring seat 402, a first support rod 403, an exhaust groove 404, a second support rod 405, a sliding block 406, a tension spring 407, a connecting seat 408, a counterweight 409, an air inlet groove 410, a ventilation groove 411, an electromagnet 412, a bearing seat 413 and a feeding port 414. Fixed ring seats 402 are arranged at both outer ends of the outside of the box body 401, and a first support rod 403 is arranged at the outer end of the top of the fixed ring seat 402. An exhaust groove 404 is opened inside the first support rod 403. A second support rod 405 is arranged at the outer end of the bottom of the fixed ring seat 402. The outer ends of the first support rod 403 and the second support rod 405 are connected with a sliding block 406. A tension spring 407 is arranged inside the first support rod 403, and a connecting seat 408 is arranged at the bottom end of the tension spring 407. A counterweight 409 is arranged at the outer end of the bottom of the connecting seat 408, and an air inlet groove 410 is opened inside the counterweight 409. A ventilation groove 411 is opened inside the connecting seat 408. An electromagnet 412 is arranged at the inner side of the bottom of the box body 401, and a bearing seat 413 is arranged at the inner side of the right part of the box body 401. A feeding port 414 is arranged at the top of the box body 401.

[0021] The specific operation is as follows. The staff opens the cover plate at the top of the feeding port 414, which can open the box body 401. At this time, the staff can put the chemical masterbatch to be dried into the box body 401 through the material passing groove 203. Since the box body 401 is cylindrical, the chemical masterbatch put into the box body 401 can enter the bottom end of the box body 401 for temporary storage. After the chemical masterbatch is put in, the staff closes the cover plate at the top of the feeding port 414, and then the device can perform the drying operation.

[0022] Please refer toFigures 5 to 8 The support component 2 includes a support member 201, a positioning ring seat 202, a material passing groove 203, and a sliding groove 204. The outer end of the support member 201 is provided with the positioning ring seat 202. Through the material grooves 203 are opened on the upper and lower sides of the positioning ring seat 202. The sliding groove 204 is opened inside the positioning ring seat 202. The motor 3 and the box body 401 are eccentrically distributed, and the motor 3 and the positioning ring seat 202 are concentrically distributed. The sliding block 406 is an integral structure with the first support rod 403 and the second support rod 405, and the sliding block 406 slides inside the sliding groove 204. The connecting seat 408 and the counterweight 409 are an integral structure, and the connecting seat 408 is elastically connected to the first support rod 403 through the tension spring 407. The air inlet groove 410 is communicated with the air vent groove 411, and the displacement of the connecting seat 408 makes the air vent groove 411 communicate with the exhaust groove 404. The bottom contour of the counterweight 409 matches the inner contour shape of the box body 401, and the downward movement of the counterweight 409 exposes the air inlet groove 410. The heating component 5 is arranged at the right end of the top of the base 1. The heating component 5 includes a hot air blower 501, a connecting pipe 502, a ventilation duct 503, an air outlet 504, a return spring 505, and an armature pressing block 506. The outer end of the hot air blower 501 is connected with the connecting pipe 502, and the ventilation duct 503 is opened inside the connecting pipe 502. The air outlet 504 is opened at the outer end of the connecting pipe 502. The return spring 505 is arranged inside the bottom of the connecting pipe 502, and the armature pressing block 506 is arranged at the outer end of the return spring 505. The hot air blower 501 is communicated with the air outlet 504 through the ventilation duct 503. The connecting pipe 502 is concentrically distributed with the positioning ring seat 202 and the motor 3. The return spring 505 is elastically connected with the armature pressing block 506, and the armature pressing block 506 is electromagnetically adsorbed and connected with the electromagnet 412; The specific operation is as follows. When the device performs the drying operation, the motor 3 and the hot air blower 501 in the heating component 5 are started. The motor 3 drives the drying box component 4 to rotate eccentrically around the bearing seat 413 through the output end. At the same time, the hot air blower 501 conveys hot air into the ventilation duct 503 through the connecting pipe 502. Since the ventilation duct 503 is connected to the inside of the box body 401 through the air outlet 504, the hot air can blow on the surface of the chemical masterbatch to promote its drying. The eccentric rotation of the box body 401 driven by the motor 3 can turn the chemical masterbatch inside the box body 401 to ensure that the chemical masterbatch can be fully dried. The eccentric rotation can also cause the box body 401 to vibrate periodically. The periodic vibration combined with the turning of the chemical masterbatch can further improve the drying uniformity, so as to avoid the situation that the chemical masterbatch in the middle cannot be dried. Through the operation of eccentric rotation, the device can realize the turning and vibration of the chemical masterbatch only by rotation, which reduces the operation difficulty and maintenance difficulty of the device. The fixed ring seat 402 at the outer end of the box body 401 is connected to the first support rod 403 and the second support rod 405. The first support rod 403 and the second support rod 405 are connected to the sliding groove 204 inside the positioning ring seat 202 through the sliding block 406. During the circumferential rotation of the box body 401, due to the sliding of the sliding block 406 inside the sliding groove 204, the box body 401 can improve the stability during the eccentric rotation through the external limit during the rotation. In addition, the cooperation of the tension spring 407 and the counterweight 409 can form an elastic system. When the box body 401 rotates eccentrically and vibrates, after the counterweight 409 rotates to the top with the box body 401, it will move downward due to inertia. At this time, the tension spring 407 will generate a reverse pulling force to form a dynamic balance. Through the cooperation with the limit of the positioning ring seat 202, the vibration amplitude of the box body 401 can be controlled and stabilized. In addition, when the connecting seat 408 drives the counterweight 409 to move downward, the air inlet groove 410 inside it will be exposed, and the downward movement of the connecting seat 408 will connect the exhaust groove 404 with the ventilation groove 411. At this time, the water vapor generated by drying inside the box body 401 can be discharged from the device through the air inlet groove 410, the ventilation groove 411 and the exhaust groove 404. Since the exhaust groove 404 is only opened when the counterweight 409 moves downward due to gravity, through this operation, the heat inside the box body 401 can be reduced from being dissipated due to the discharge of water vapor, and the situation that the discharge of water vapor is too slow to affect the drying effect can be avoided. In addition, during the drying process of the chemical masterbatch by the device, the electromagnet 412 inside the box body 401 can be turned on. Since the box body 401 and the connecting pipe 502 are eccentrically distributed, when the electromagnet 412 approaches the connecting pipe 502, the adsorption force of the electromagnet 412 can pull the armature pressing block 506. During the process of the armature pressing block 506 being pulled by the electromagnetic force, it can stretch the return spring 505 and move out of the connecting pipe 502. After the armature pressing block 506 moves out, it can press the chemical masterbatch at the bottom of the box body 401. When the water inside the chemical masterbatch evaporates,The chemical masterbatch agglomerated due to moisture remains in an agglomerated state. By pressing with the armature pressing block 506, the agglomerated chemical masterbatch can be broken up under the action of external force. Through this operation, subsequent additional breaking steps can be avoided. In addition, due to the principle that the volume of the fluid substance is relatively large and it will be closer to the upper part, by breaking up the agglomerated chemical masterbatch, the drying effect of the chemical masterbatch can be further improved. After the chemical masterbatch is dried, the box body 401 rotates to the position where the feeding port 414 faces downward. At this time, the staff opens the cover of the feeding port 414, and the dried chemical masterbatch can be removed from the equipment through the feeding port 414 and the material passing groove 203.,

[0023] When the staff opens the cover plate at the top of the feeding port 414, the box body 401 can be opened. At this time, the staff can put the chemical masterbatch to be dried into the interior of the box body 401 through the material passing groove 203. Since the box body 401 is cylindrical, the chemical masterbatch put into the interior of the box body 401 can enter the bottommost part of the box body 401 for temporary storage. After the chemical masterbatch is put in, after the staff closes the cover plate at the top of the feeding port 414, the equipment can carry out the drying operation; Then when the equipment is carrying out the drying operation, the motor 3 and the hot air blower 501 in the heating component 5 will be started. The motor 3 drives the drying box component 4 to rotate eccentrically around the bearing seat 413 through the output end. At the same time, the hot air blower 501 conveys hot air into the ventilation duct 503 through the connecting pipe 502. Since the ventilation duct 503 is communicated with the interior of the box body 401 through the air outlet 504, the hot air can blow on the surface of the chemical masterbatch to promote its drying. The eccentric rotation of the box body 401 driven by the motor 3 can make the box body 401 turn over the chemical masterbatch inside to ensure that the chemical masterbatch can be fully dried. Moreover, the eccentric rotation can also make the box body 401 vibrate periodically. The periodic vibration combined with the turning over of the chemical masterbatch can further improve the drying uniformity to avoid the situation that the chemical masterbatch in the middle cannot be dried. Through the operation of eccentric rotation, the equipment can realize the turning over and vibration of the chemical masterbatch only by rotation, which reduces the operation difficulty and maintenance difficulty of the equipment; Subsequently, since the fixed ring seat 402 at the outer end of the box body 401 is connected to the first support rod 403 and the second support rod 405, and the first support rod 403 and the second support rod 405 are connected to the sliding groove 204 inside the positioning ring seat 202 through the sliding block 406. During the circumferential rotation of the box body 401, due to the sliding of the sliding block 406 inside the sliding groove 204, the stability of the box body 401 during eccentric rotation can be improved through the external limit during rotation. In addition, the cooperation of the tension spring 407 and the counterweight 409 can form an elastic system. When the box body 401 rotates eccentrically and vibrates, after the counterweight 409 rotates to the top with the box body 401, it will move downward under the action of inertia. At this time, the tension spring 407 will generate a reverse pulling force to form a dynamic balance. Through the cooperation with the limit of the positioning ring seat 202, the vibration amplitude of the box body 401 can be controlled and stabilized; Subsequently, when the connection seat 408 drives the counterweight 409 to move downward, the air inlet groove 410 inside it will be exposed. When the connection seat 408 moves downward, the exhaust groove 404 will be connected to the ventilation groove 411. At this time, the water vapor generated by drying inside the box body 401 can be discharged from the device through the air inlet groove 410, the ventilation groove 411 and the exhaust groove 404. Since the exhaust groove 404 is only opened when the counterweight 409 moves downward under gravity, through this operation, the heat inside the box body 401 can be prevented from being dissipated due to the discharge of water vapor, and the situation that the slow discharge of water vapor affects the drying effect can be avoided; Finally, during the drying process of the chemical masterbatch by the device, the electromagnet 412 inside the box body 401 can be turned on. Since the box body 401 and the connecting pipe 502 are eccentrically distributed, when the electromagnet 412 approaches the connecting pipe 502, the adsorption force of the electromagnet 412 can pull the armature pressing block 506. During the process of the armature pressing block 506 being pulled by the electromagnetic force, the return spring 505 can be stretched and moved out from the inside of the connecting pipe 502. After the armature pressing block 506 is moved out, it can press the chemical masterbatch at the bottom of the box body 401. When the water inside the chemical masterbatch evaporates, the chemically bonded masterbatch due to water adhesion will still be in a bonded state. Through the pressing of the armature pressing block 506, the bonded chemical masterbatch can be dispersed under the action of external force. Through this operation, the subsequent additional dispersion steps can be omitted. In addition, due to the principle that the volume of fluid substances is relatively large and they tend to be upward, by dispersing the bonded chemical masterbatch, the drying effect of the chemical masterbatch can be further improved. After the chemical masterbatch is dried, the box body 401 rotates to the position where the feeding port 414 faces downward. At this time, the staff opens the cover of the feeding port 414, and the dried chemical masterbatch can be removed from the device through the feeding port 414 and the material passing groove 203.
