Description

TECHNICAL FIELD

[0001] The utility model belongs to material heating equipment technical field, especially, relate to a kind of automatic rotation feeding device. BACKGROUND

[0002] It is just in the vigorous development of each high-end industry, urgently call more adaptable, performance more outstanding feeding equipment, traditional feeding device is in this strong development flood gradually force from the heart, expose many thorny problems, especially when facing the test such as multi-particle size material processing, unattended operation demand.

[0003] On the one hand, material adaptability is poor. In the production process, the particle size of the material is complex, including large particle material, small particle and even dust-like material. Traditional feeding equipment often cannot flexibly adjust the feeding parameters according to different particle sizes, resulting in that during material conveying, large particles are easy to jam and block the feeding port, small particles are difficult to uniformly disperse, and dust materials cannot be stably suspended and conveyed, ultimately causing disorder of feeding and discharging rhythm, greatly reducing feeding efficiency and precision, and seriously affecting the continuity of the overall production process.

[0004] On the other hand, heating and material protection are insufficient. Most conventional devices have rough heating methods in the heating material link, and the material is unevenly heated, which is prone to local overheating, causing material adhesion and carbonization. Not only does it reduce product purity, but it also greatly reduces the service life of the material pipe, increasing the high operating cost of frequent replacement of the material pipe. In addition, some materials are active and prone to oxidation and hydrolysis. Traditional equipment lacks effective means to isolate oxygen, and the risk of material deterioration is high, making it difficult to guarantee product qualification rate.

[0005] Furthermore, the stability of the equipment is poor. Loose sealing at key positions is a common problem, which not only causes waste but also pollutes the working environment. The rotating parts lack stable support, and the running is prone to yaw and jam, which aggravates the wear of the parts, increases the probability of sudden failure, and requires frequent maintenance and repair, which cannot meet the requirements of long-term unattended stable operation.

[0006] In addition, the equipment maintenance and operation convenience are low. The structure of the traditional device is fixed, and it is difficult to accurately adjust the position after the parts wear and deform. The disassembly and replacement are complicated, the downtime is long, and the production progress is slowed down. The equipment cleaning and maintenance are inconvenient, the discharging efficiency is low, the labor intensity is high, the fatigue is intensified, and the operation accuracy is reduced.

[0007] In summary, the existing feeding device cannot adapt to the current efficient automatic and unattended production mode, and a new automatic rotary feeding device is urgently needed to overcome the above technical problems and meet the increasing demand for refinement and intelligentization of industrial production. UTILITY MODEL CONTENTS

[0008] Therefore, the automatic rotary feeding device is provided to solve some or all of the problems in the background art and to realize an unattended mode of the feeding device to some extent.

[0009] To achieve the above object, the technical scheme of the utility model is as follows:

[0010] An automatic rotary feeding device comprises a feeding unit, a discharging unit, a support surface and a material pipe.

[0011] The feeding unit comprises a feeding pipe, a spiral blade shaft, a magnetic fluid sealing device A, a connecting frame, a feeding motor, a rotating part A and a rotating unit. The rotating part A is a rotatable part with a gear on the outer periphery. The feeding pipe and the feeding motor are connected through the connecting frame. The spiral blade shaft is rotatably arranged in the feeding pipe. One end of the spiral blade shaft is connected to the output end of the feeding motor. The connecting part is connected through a rotatable sealing device, preferably a magnetic fluid sealing device, to ensure that the part can be sealed when the spiral blade shaft is rotated in the feeding pipe under the driving of the feeding motor. The magnetic fluid sealing device A is sleeved on the feeding pipe. The magnetic fluid sealing device A is arranged on the support surface. At least one of the feeding pipe, the connecting frame and the feeding motor is connected to the support surface. The rotating part A is arranged at the end of the magnetic fluid sealing device A. The rotating unit drives the rotating part A to rotate. The rotating unit is arranged at a position on the support surface or a position capable of effectively driving the rotating part A. One end of the material pipe is connected to the rotating part A. The feeding pipe is provided with a feeding port.

[0012] The discharging unit comprises a magnetic fluid sealing device B and a rotating part B. The rotating part B is arranged at the end of the magnetic fluid sealing device B. The other end of the material pipe is connected to the rotating part B.

[0013] The magnetic fluid sealing device utilizes the special properties of magnetic fluid under the action of a magnetic field to achieve sealing effect. It is a non-contact sealing method between mechanical sealing and packing sealing. The magnetic fluid is composed of nanoscale magnetic particles, such as ferrite particles, uniformly dispersed in water or oil, and an appropriate amount of surfactant to maintain the stability of the particles. The device generally includes a rotating shaft, a magnet (permanent magnet or electromagnet) and a magnetic pole shoe. The magnet is responsible for generating a magnetic field. The magnetic pole shoe is used to accurately guide the magnetic field to focus on the gap between the rotating shaft and the fixed part. The magnetic fluid fills the gap. Once a magnetic field exists, the magnetic particles in the magnetic fluid will align along the direction of the magnetic field, forming a "magnetic liquid sealing ring" that can withstand a certain pressure difference and effectively block gas and liquid from leaking through the gap.

[0014] The heating component is connected to an appropriate power source, and the heating element rapidly heats up according to a preset temperature curve. The heat is precisely and uniformly spread to the pipe wall through heat conduction, and then transferred to the material in dynamic flow inside the pipe; as the device rotates, the material continuously rolls and contacts the heated pipe wall in all directions, achieving uniform heating effect.

[0015] In a structure that can optimize the foregoing scheme, a frame table is further included, the support surface is arranged on the frame table, and the support surface arranged on one side of the discharging unit is connected to the frame table in an openable and closable manner. Preferably, the connection is a hinged connection, specifically, a hinge connection. The support surface can be inclined along the direction of movement of the material, and the vertical height of the feeding unit is greater than that of the discharging unit after the inclination. The frame table and the openable and closable connection structure are added to support the support surface and the complex components thereon that bear different particle sizes of the material, maintain the overall rigidity of the device, and enable it to withstand the impact and vibration caused by the frequent feeding and discharging of the material of different particle sizes, effectively preventing the material from stratifying and scattering. The openable and closable feature of the device not only helps to deal with the material that may be caked and sticky after heating, but also enables the device to be operated remotely. When the device is opened and closed, the locking device is unlocked, and the auxiliary device is manually or remotely controlled to rotate the support surface around the hinge as the axis and adjust to the ideal discharging angle. The material can then be smoothly discharged along the inclined support surface with the help of gravity, improving the discharging efficiency and completeness. After the operation is completed, the device is locked again, and the hinge bears the torsion and slight displacement during the operation of the device. This structure also facilitates quick cleaning and maintenance of the device, making it more efficient and convenient to clean residual large particle materials and unblock dust blockage, meeting the requirements of unattended operation, reducing manual auxiliary discharging operation, and reducing labor costs. In addition, the frame table also has the function of raising the operation height. During the daily operation and maintenance, material loading, or parameter adjustment of the device, appropriate operation height is particularly important. By raising the device to an appropriate position, the operator does not need to bend over or crouch for a long time, and the body can maintain a relatively comfortable posture, reducing the feeling of fatigue, thereby more accurately and efficiently completing various operations and further improving the convenience and safety of the device.

[0016] Further, it also includes a lifting unit, the lifting unit includes an electric push rod, a movable shaft A, a movable shaft B, the movable shaft A is arranged at the lower part of the support surface, the movable shaft B is arranged inside the frame table, and the two ends of the electric push rod are respectively rotationally connected with the movable shaft A and the movable shaft B. The electric push rod can push the support surface to open and close. The electric push rod can be accurately telescoped according to the instruction of the control system, and is rotationally connected through the movable shaft A and the movable shaft B, so as to stably drive the support surface to open and close around the hinge point. When encountering large particle materials, large opening degree discharging can be quickly realized; for small particle and dust materials, stable and small amplitude opening and closing are realized to prevent dust raising and leakage, and the unmanned fine operation is matched. Therefore, the disadvantages of manual opening and closing are abandoned, the labor intensity is reduced, the material spilling and equipment damage are avoided, the action of the support surface is accurately controlled, the component wear caused by opening and closing impact is reduced, the stable operation of the equipment is maintained, the automation and intelligent production trend is matched, and remote monitoring and integrated control of the equipment are facilitated.

[0017] Further, it also includes an auxiliary support rod, the auxiliary support rod is two groups, and the two ends of the auxiliary support rod are respectively connected with the support surface and the frame table. The auxiliary support rod is a hydraulic rod, one end of which is connected with the bottom of the support surface, and the other end is connected with the inner side of the frame table, and the two groups of auxiliary support rods are oppositely arranged. The auxiliary support rod can stably support the opening and closing of the support surface, and prevent the support surface from suddenly falling when the electric push rod suddenly fails. During normal operation, the auxiliary support rod cooperates with the electric push rod to stably support the equipment and maintain the support surface to be stable, so as to ensure normal operation of the equipment. Once the electric push rod suddenly fails, the hydraulic rod starts immediately by relying on the internal energy storage, the piston rod rapidly extends, and the support surface position is locked to prevent it from falling, so as to avoid the equipment and the material from being damaged and scattered. The effect is particularly obvious when handling large particle materials; when encountering dust materials, dust hazards can also be eliminated, and the safety of surrounding personnel is ensured. Thanks to this double protection mechanism, the reliability and emergency disposal capacity of the equipment are improved, the unplanned downtime is greatly reduced, the maintenance cost is reduced, the equipment can continuously and safely and stably operate in the unattended state, the equipment precision is maintained, and the service life is prolonged; during the opening and closing process of the support surface, the auxiliary support rod can adaptively adjust the support force and the rod length.

[0018] In a structure that can optimize the foregoing scheme, the material pipe is a quartz pipe, the middle of the quartz pipe is outwardly expanded to form a heating chamber. The heating chamber is externally surrounded by a heating furnace, and the material in the heating chamber is heated without direct contact with the heating furnace. The device uses a quartz pipe material pipe, which is resistant to high temperature, has strong chemical inertness, and has fast heat conduction. The middle of the pipe is outwardly expanded to form a heating chamber, and the outer side is surrounded by a heating furnace. The quartz pipe effectively isolates the material from the heating furnace, avoiding material pollution and chemical reaction, and adapting to multiple particle sizes of material. The core of large particle material, small particles and dust material can be quickly and uniformly heated, optimizing the effect of rotary heating. The heating furnace radiates heat outwardly, the quartz pipe quickly absorbs and uniformly conducts to the heating chamber, and the material continuously contacts the heated chamber wall during rotary flow to absorb heat. The special structure of the heating chamber also promotes the circulation of hot air, eliminating the occurrence of dead angles of materials of various particle sizes. In this way, the service life of the material pipe is significantly prolonged, reducing the operation and maintenance cost of frequent replacement of the material pipe, and meeting the requirements of unattended long-term operation. The heating chamber with precise temperature control improves the heating quality of the material, reduces the risk of material adhesion and carbonization, and ensures product purity.

[0019] In a structure that can optimize the foregoing scheme, the magnetic fluid sealing device A is provided with a gas port A on the extension pipeline; the magnetic fluid sealing device B is provided with a gas port B on the extension pipeline. Inert gas is introduced through the gas port A, enters the material pipe, and protects the material in the heating chamber. The inert gas is then discharged through the gas port B; the gas inlet direction of the gas port A and the gas port B can be changed to change the gas flow direction in the material pipe. The magnetic fluid sealing device A is provided with a gas port A on the extension pipeline, and the magnetic fluid sealing device B is provided with a gas port B on the extension pipeline. Different particle sizes of materials have different characteristics, and some are prone to oxidation and deterioration. Therefore, an external gas source is connected through the gas port to introduce inert gas to create an oxygen-free or low-oxygen environment to prevent oxidation and hydrolysis of the material. By precisely controlling the valve, the gas flow and flow direction are controlled according to the process requirements, so that the inert gas enters the material pipe smoothly, which can protect the material, especially for fine small particles and easily oxidized materials, and greatly improve the product pass rate. The gas flow can also be used to wrap and carry volatile substances and dust, which are orderly discharged from the corresponding gas port. In this way, the material pipe is cleaned, the dust accumulation and particle blockage are reduced, the equipment maintenance frequency is reduced, and stable gas protection is provided for unattended operation, reducing manual inspection intervention.

[0020] In a structure that can optimize the foregoing scheme, a rotating support seat is further included, which is arranged on the support surface and cooperates with the rotating part B of the magnetic fluid sealing device B. When the rotating part B rotates, the support wheel on the rotating support seat cooperates with the rotation to play a supporting and stabilizing role. The force condition of multi-particle size material conveying is complex, large particle materials produce impact, small particle materials cause friction, and dust can adhere, which all threaten the rotation stability. The rotating support seat relies on its own stable mechanical structure, and when the rotating part B rotates, its support wheel responds immediately, relies on the mechanical structure characteristics, automatically adapts to the dynamic force change during material conveying, continuously and stably provides radial and axial support force, and guarantees smooth rotation. Thanks to the support of the rotating support seat, the rotating part B can reduce the deflection and jamming, reduce the wear of parts, prolong the service life, and reduce the equipment maintenance cost; the equipment can also maintain high-precision operation, continuously and stably convey materials, avoid material leakage and spilling problems, and meet the unattended mode, which is beneficial to remote monitoring and stable operation of the equipment.

[0021] In a structure that can optimize the foregoing scheme, the rotating unit includes a rotating wheel, a driving motor, a tensioning wheel, and a transmission belt. Preferably, the rotating wheel is a gear, the driving motor is arranged on the lower surface of the support surface, the rotating wheel is connected with the output end of the driving motor, the transmission belt passes through the support surface to connect the rotating wheel with the rotating part A, and the tensioning wheel is arranged on the support surface and cooperates with the transmission belt to press on the transmission belt. The rotating unit of the equipment is composed of the rotating wheel, the driving motor, the tensioning wheel, and the transmission belt. After the driving motor is powered on, it starts to drive the rotating wheel to rotate stably, the transmission belt immediately transmits power to the rotating part A, and the tensioning wheel maintains the proper tension of the belt throughout the process. In actual production, the particle sizes of each batch of materials are different, some batches are large particles, some batches are small particles, and some batches are dust. The rotating unit is designed for this purpose. Before feeding each batch of materials, the parameters such as rotating speed and torque are preset according to the particle size characteristics, and the driving motor can accurately generate power to drive the spiral blade shaft to rotate at a predetermined pace. When handling large particle materials, the driving force is sufficient to steadily push the materials forward; when handling small particle materials, the operation is stable to evenly disperse the materials; and when dust materials are encountered, the operation is adjusted to an appropriate state to convey the materials in a suspended state. This allows the materials to be orderly fed in and out, meets the requirements of unattended automation, accurately controls the feeding and discharging pace of each batch of materials, matches the corresponding flow and speed, improves the feeding efficiency and accuracy. Moreover, the motor responds quickly, and when the subsequent production plan is adjusted or the material characteristics change, it can quickly switch the operating state; stable power output also provides a guarantee for long-term unattended operation of the equipment, reducing the frequency of manual intervention.

[0022] In a structure that can optimize the foregoing scheme, a protective cover is further included, which is arranged above the rotating part A. The protective cover is fixed on the support surface, and the position of the protective cover is matched with the rotating part A. The protective cover effectively blocks the contact between the operator and the high-speed rotating part and the easily-broken transmission belt, avoids the risk of accidental injury; at the same time, the protective cover blocks the invasion of sundries into the rotating unit, maintains the cleanliness of the inside of the equipment, reduces the possibility of interference of sundries with the rotating part, reduces the frequency of equipment failure maintenance, and prolongs the service life.

[0023] In a structure that can optimize the foregoing scheme, a protective cover is further included, which is arranged above the rotating part A.

At the same time, the external material conveying device is simultaneously started, and the material continuously flows into the feed pipe 3 through the feed inlet 3-1. The spiral blade shaft 4 orderly pushes the material along the predetermined route to the material pipe 2; almost at the same time, the driving motor 10 starts to operate the driving unit. The rotating wheel 9 rotates, and the transmission belt maintains appropriate tension under the action of the tensioning wheel 11, smoothly transmitting power to the rotating part A8, prompting the material pipe 2 to start rotating at a constant speed. The material continuously tumbles in the pipe to avoid blockage and accumulation. When encountering large particle materials, the driving motor 10 increases the output power to provide sufficient power to overcome the gravity and friction of the material and push it forward; when encountering small particle materials, the motor automatically adjusts to a stable and appropriate speed to evenly disperse the material; if it is a dust material, the motor is adjusted to a specific state to allow the material to be in a suspended state in the pipe.

[0052] 3 / Precise heating and atmosphere protection: When the material enters the material pipe 2, the heating furnace is immediately powered on. The heating wire quickly heats up and radiates a large amount of heat. The quartz tube quickly and uniformly absorbs heat and conducts it to the heating bin 2-1 due to its excellent heat conduction performance. The material flows along with the material pipe, continuously contacts the heated bin wall, absorbs heat, and is uniformly heated; the special structure of the heating bin promotes the natural circulation of hot air, ensuring uniform heating of the material and reducing the risk of material adhesion and carbonization. At the same time, the inert gas flowing into the material pipe flows smoothly, isolating external oxygen and preventing material oxidation and hydrolysis; the inert gas can also wrap the impurities and dust generated by the material, and orderly discharge them from the air outlet B13-1 along the set airflow direction, maintaining the cleanliness of the material pipe.

[0053] 4 / Smooth discharging and emergency adjustment: After heating and tumbling, the material reaches the discharging unit. The rotating part B14 is stably rotated with the assistance of the rotating support seat 15, and the material is smoothly discharged from the device. Under normal conditions, the discharging is stable and orderly; if the material is heated and agglomerated or sticky, or to speed up the discharging efficiency and clean the remaining material, the operator can remotely control, unlock the locking device, and send the extension command to the electric push rod 20. The electric push rod smoothly acts according to the command, rotates the support surface 1 with the hinge as the axis, and adjusts the discharging angle. When encountering large particle materials, the electric push rod quickly extends, pushes the support surface to a large opening angle, and tilts to make the material quickly slide down; for small particle and dust materials, the electric push rod extends and retracts slightly, achieving a small opening and closing angle to prevent dust leakage. After the material is discharged, the support surface 1 is locked again, and the equipment returns to normal operation.

[0054] 5 / Regular maintenance and intelligent compensation: After long-term operation of the equipment, due to material impact, wear and temperature, conditions such as poor feeding and poor sealing may occur. At this time, the operator uses the screw slide A16 and the screw slide B17 to rotate the corresponding shaft, and the screw nut drives the connecting part to move linearly in the predetermined direction, accurately adjusting the position of the feeding pipe 3 and the magnetic fluid sealing device A5 to compensate for the wear and deformation of the parts. Regularly taking advantage of the elevated operating height of the frame table 19, maintenance personnel can disassemble and replace worn parts, efficiently complete equipment maintenance and repair work, and meet the requirements of unattended operation.

[0055] During the entire operation cycle, each component strictly operates according to the designed function, cooperates with each other, fully utilizes the advantages of automatic rotating feeding device such as high efficiency, intelligence and unattended operation, adapts to various complex working conditions, and stably and reliably conveys and processes materials.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
