Description

Technical Field

[0001] This invention belongs to the field of transportation technology, and specifically discloses a material buffering device and method suitable for the production of polyvinyl chloride paste resin. Background Technology

[0002] Polyvinyl chloride paste resin (PVC paste resin), as an important polymer material, is widely used in high-value-added fields such as medical devices, automotive interiors, artificial leather, coatings, and adhesives due to its good film-forming properties, excellent product feel, and strong chemical stability. With the increasing demands for uniformity and purity in material performance for high-end products, extremely stringent requirements have been placed on the quality control of PVC paste resin raw materials, especially the stability of its primary micro-particle morphology.

[0003] In existing production processes, the primary product of PVC paste resin obtained after polymerization is a fine-particle solid (typically in the range of 1-100 micrometers). These micro-particle resins have a huge specific surface area, resulting in extremely unique physical properties, the most prominent being their strong hygroscopicity. In subsequent intermediate processes such as buffering, transfer, and temporary storage, the material readily absorbs moisture from the ambient air. After absorbing moisture, the physicochemical properties of the microparticle surface change, leading to severe adhesion, aggregation, and even clumping between particles under the influence of van der Waals forces and liquid bridging forces. This phenomenon is particularly pronounced in traditional buffer devices such as silos and hoppers.

[0004] Currently, most industry-standard buffer devices focus on static storage and gravity feeding, lacking specific designs for highly hygroscopic and easily adherent microparticle materials. Inside the device, especially in the conical feeding section and on the inner wall, materials frequently experience problems such as wall adhesion, bridging, and rodent holes, leading to poor flow, unstable rates, or even complete interruptions. This not only severely disrupts the rhythm of continuous production, causing decreased production line efficiency and increased energy consumption, but also forces operators to perform frequent manual interventions, such as tapping the hopper or using air cannons to clear blockages. Such interventions are not only labor-intensive and pose safety risks, but also introduce uncontrollable mechanical disturbances, easily causing secondary breakage or contamination of the material, negatively impacting the particle size distribution, impurity content, and rheological properties of the final product, thus compromising batch consistency and reliability in high-end applications.

[0005] Therefore, the present invention aims to provide an innovative material buffering device and method to overcome the inherent defects of the prior art. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a material buffering device suitable for the production of polyvinyl chloride paste resin. The device includes a movable support mechanism, a buffer tank, a drive mechanism, and a rotating shaft. The buffer tank is fixedly mounted above the movable support mechanism. The rotating shaft is located inside the buffer tank and rotates inside the buffer tank via the drive mechanism. A rotary joint is sleeved on the upper part of the rotating shaft, and an air inlet pipe is connected to one end of the rotary joint. A connecting cylinder shell is fixedly sleeved on the lower part of the rotating shaft. An air storage plate is fixedly sleeved on the outer part of the connecting cylinder shell. The air storage plate is connected to connecting rods via air inlets installed on both sides of its interior. The upper part of each connecting rod is fixedly connected to the outer part of the air storage plate via mounting components. A material passage cylinder is fixedly mounted on the lower end of each connecting rod. Multiple air outlets are provided on the outer part of each material passage cylinder, and a protective component is provided at one end of each air outlet. Resistance buffer components are crosswise arranged on the outer parts of two material passage cylinders. A spiral blade is fixedly mounted on the lower part of the rotating shaft, and a material discharge passage cavity is provided between the spiral blade and the inside of the buffer tank.

[0007] In the above technical solution, the mobile support mechanism further includes a mobile frame, on the upper surface of which are four vibration support rods arranged in a rectangle, and the buffer tank is clamped between the four vibration support rods.

[0008] In the above technical solution, a discharge pipe is further installed inside the lower part of the buffer tank, and an inclined spiral conveyor is installed below the discharge pipe. A support rod is fixedly installed on one side of the upper surface of the mobile frame, and the support rod is fixedly set on the lower part of the spiral conveyor on one side.

[0009] In the above technical solution, the driving mechanism further includes a motor and a mounting bracket. The mounting bracket is fixedly mounted on the upper surface of the buffer tank, the motor is fixedly mounted inside the mounting bracket, and the motor output shaft is fixedly connected to the upper end of the rotating shaft.

[0010] In the above technical solution, the air intake component further includes a J-shaped rigid pipe installed inside the lower part of the air storage plate. The J-shaped rigid pipe is connected to the inside of the connecting rod. The two ends of the inside of the connecting cylinder shell are connected to the inside of the air storage plate through a through pipe installed in a connected manner.

[0011] In the above technical solution, the mounting component further includes a limiting rod that is fixedly inserted inside the upper part of the connecting rod, a connecting seat is sleeved on the outside of the limiting rod, and a slot for fixed connection with the connecting seat is opened inside the gas storage plate.

[0012] In the above technical solution, the protective component further includes a filter disc installed inside one end of the air outlet. A limiting shell is rotatably sleeved on the outside of the filter disc. An annular groove is opened inside the limiting shell, and multiple balls are arranged inside the annular groove. The multiple balls roll in contact with the outside of the filter disc. A movable shell is installed at the end of the limiting shell away from the filter disc. An air hole is opened inside the movable shell. Rotary blades are installed at equal intervals along the circumferential direction on the inner wall of the movable shell. A soft brush is fixedly installed on the upper edge of the rotary blades.

[0013] In the above technical solution, the resistance-reducing component further includes two sets of connecting members. The two sets of connecting members are respectively fixedly installed on the upper surface and the outer side of the material feeding cylinder. The material feeding V-plate is installed on the side of the two sets of connecting members away from the material feeding cylinder. A low-temperature flexible heat-conducting tape is fixedly installed on the outer side of the material feeding cylinder and away from the material feeding V-plate.

[0014] A method for using a material buffer device suitable for the production of polyvinyl chloride paste resin, comprising the following steps:

[0015] S1: Put the polyvinyl chloride paste resin material into the buffer tank, so that the material tube is buried inside the material;

[0016] S2: Dry gas is introduced into the material cylinder through the air inlet pipe, rotary joint and air storage plate. The gas is dispersed into the material through the air outlet and its protective components to prevent the material from clumping and absorbing moisture.

[0017] S3: Start the drive mechanism to drive the shaft to rotate, causing the feeding cylinder to rotate and agitate the material. At the same time, the spiral blades rotate to promote the material to tumble inside the buffer tank, while the resistance-reducing components disturb the material flow. The low-temperature flexible heating tape heats the material synchronously with the rotation of the feeding cylinder.

[0018] S4: The processed material falls through the discharge passage and is then discharged from the buffer tank via a screw conveyor.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention introduces dry gas into a rotating feed cylinder embedded inside the material, allowing the gas to escape evenly from multiple outlets. This improves the local low-humidity environment inside the material, effectively inhibiting the surface adhesion and agglomeration of polyvinyl chloride paste resin microparticles due to moisture absorption, and fundamentally preventing the material from clumping during the buffering process.

[0021] 2. This invention employs a multi-layered design of rotary ventilation, mechanical agitation, and auxiliary heating, which allows the material feed cylinder and external resistance buffer to rotate inside the buffer tank. This continuously and gently disrupts the material flow, breaking up small aggregates formed in the early stages. Simultaneously, the auxiliary heating further reduces the local humidity of the material, and combined with the conveying action of the spiral blades, ensures that the material moves uniformly and smoothly throughout the buffer space. This completely avoids problems such as adhesion, bridging, or rat holes at the tank walls or discharge port, ensuring the continuous and stable operation of the production line.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-8 The illustrated material buffer device for the production of polyvinyl chloride paste resin includes a movable support mechanism, a buffer tank 2, a drive mechanism, and a rotating shaft 9. The buffer tank 2 is fixedly mounted above the movable support mechanism. The rotating shaft 9 is located inside the buffer tank 2 and rotates within it via the drive mechanism. A rotary joint 5 is sleeved on the upper part of the rotating shaft 9. One end of the rotary joint 5 is connected to an air inlet pipe 21. A connecting cylinder shell 23 is fixedly sleeved on the lower part of the rotating shaft 9. An air storage plate 8 is fixedly sleeved on the outside of the connecting cylinder shell 23. The air storage plate 8 is connected to connecting rods 20 via air inlets installed on both sides of its interior. The upper part of each connecting rod 20 is fixedly connected to the outside of the air storage plate 8 via mounting parts. A through-hole is fixedly installed at the lower end of each connecting rod 20. The material cylinder 11 has multiple air outlets 13 on its exterior, and each air outlet 13 has a protective component at one end. The two material cylinders 11 are respectively provided with cross-shaped resistance buffers. The spiral blades 12 are fixedly installed on the lower exterior of the rotating shaft 9, and the spiral blades 12 and the buffer tank 2 have a material discharge passage cavity. The movable support mechanism includes a movable frame 1. Four vibrating support rods 7 arranged in a rectangle are installed on the upper surface of the movable frame 1. The buffer tank 2 is clamped between the four vibrating support rods 7. A discharge pipe is connected to the lower interior of the buffer tank 2. An inclined spiral conveyor 3 is connected to the lower interior of the discharge pipe. A support rod is fixedly installed on one side of the upper surface of the movable frame 1. The support rod is fixedly installed on the lower exterior of one side of the spiral conveyor 3.

[0034] In this embodiment, the vibration support rod 7 can generate micro-vibration, which can assist in material feeding during the feeding process;

[0035] The air inlet pipe 21 can be connected to dry gas, and then connected to the inside of the air storage plate 8 through the air inlet component, and finally delivered to the outside of the material passing cylinder 11, and sprayed out through the air outlet 13. The inside of the material passing cylinder 11 is a cylindrical hollow structure, which facilitates airflow.

[0036] The bottom of the mobile frame 1 is equipped with lockable casters for easy and flexible transportation of the device. The upper part of the vibrating support rod 7 is made of spring steel, and a vibrating motor can be installed on the outside to cooperate with the subsequent buffer tank 2 for material discharge. The vibration of the vibrating support rod 7 can be transmitted to the buffer tank 2, thereby helping to break the adhesion between the material and the tank wall. During the subsequent material discharge, the material flows through the discharge pipe into the inside of the screw conveyor 3, and then the screw conveyor 3 transfers the material.

[0037] The support poles provide stable support for the screw conveyor auger 3, preventing it from shifting or shaking due to vibration during operation, ensuring the continuity and stability of material conveying, and ultimately achieving controllable material output.

[0038] Specifically, the mobile support mechanism provides stable load-bearing capacity and flexible transfer capability for the overall device; the buffer tank 2 serves as a material storage cavity, providing space for subsequent processing; the drive mechanism drives the rotating shaft 9 to rotate, causing the material feeding cylinder 11 and the spiral blades 12 to move synchronously, realizing material agitation and conveying; the dry gas introduced by the air inlet pipe 21 is transmitted to the material feeding cylinder 11 through the rotary joint 5, connecting cylinder shell 23, air storage plate 8, and connecting rod 20, and is evenly dispersed into the material from the air outlet 13 to inhibit moisture absorption and agglomeration; the protective components prevent material from blocking the air passage, the resistance buffer enhances the material disturbance effect, and the material drop passage ensures the smooth fall of the material. All components work together to achieve anti-caking, anti-sticking, and stable conveying during the material buffering process.

[0039] The drive mechanism includes a motor 4 and a mounting bracket 6. The mounting bracket 6 is fixedly mounted on the upper surface of the buffer tank 2, and the motor 4 is fixedly mounted inside the mounting bracket 6. The output shaft of the motor 4 is fixedly connected to the upper end of the rotating shaft 9.

[0040] In this embodiment, the mounting bracket 6 can provide stable support for the motor 4 when it is driven. The motor 4 can drive the rotating shaft 9 and the structure outside the rotating shaft 9 to rotate inside the buffer tank 2, so as to achieve the effect of turbulence and anti-caking.

[0041] The air intake component includes a J-shaped rigid pipe 17 installed inside the lower part of the air storage plate 8. The J-shaped rigid pipe 17 is connected to the inside of the connecting rod 20. The two ends of the connecting cylinder shell 23 are connected to the inside of the air storage plate 8 through the through pipe 22 installed in a connected manner.

[0042] In this embodiment, the J-shaped rigid tube 17 can be made of stainless steel. When connecting, one end is connected to the gas storage plate 8 and the other end is connected to the inside of the connecting rod 20.

[0043] Specifically, external drying gas enters the internal channel of the rotating shaft 9 through the inlet pipe 21 and flows into the connecting cylinder shell 23. The connecting cylinder shell 23 guides the gas into the gas storage plate 8 through the through pipe 22. The gas storage plate 8 acts as a gas buffer and diverter, so that the gas is evenly distributed to the J-shaped hard pipes 17 on both sides. The J-shaped hard pipe 17 adapts to the installation space of the connecting rod 20 through a bending structure, so that the gas is stably transmitted to the connecting rod 20 and finally guided into the material passing cylinder 11, ensuring that the drying gas can reach the outlet 13 smoothly and evenly, providing a guarantee for dehumidification and anti-caking of the material.

[0044] The mounting components include a limiting rod 16 that is fixedly inserted into the upper part of the connecting rod 20, a connecting seat 15 that is sleeved on the outside of the limiting rod 16, and a slot for fixed connection with the connecting seat 15 that is adapted to be fixedly connected inside the gas storage plate 8.

[0045] In this embodiment, the limiting rod 16 is made of high-strength alloy steel, and the connecting rod 20 is fixed inside the connecting seat 15 by nuts at both ends. The connecting seat 15 is U-shaped and can be fixed inside one side of the gas storage plate 8.

[0046] The protective component includes a filter disc 24 connected to one end of the air outlet 13. A limiting shell 25 is rotatably sleeved on the outside of the filter disc 24. An annular groove is opened inside the limiting shell 25, and multiple balls 26 are arranged inside the annular groove. The multiple balls 26 roll in contact with the outside of the filter disc 24. A movable shell 14 is connected to the end of the limiting shell 25 away from the filter disc 24. An air hole is opened inside the movable shell 14. Rotary blades 27 are installed at equal intervals along the circumferential direction on the inner wall of the movable shell 14. A soft brush 28 is fixedly installed on the upper edge of the rotary blades 27. The resistance buffer includes two sets of connectors 19. The two sets of connectors 19 are respectively fixedly installed on the upper surface and the outside of the material passing cylinder 11. A material passing V plate 10 is installed on the side of the two sets of connectors 19 away from the material passing cylinder 11. A low-temperature flexible heat conduction tape 18 is fixedly installed on the outside of the material passing cylinder 11 and away from the material passing V plate 10.

[0047] In this embodiment, the filter disc 24 can block particles from entering the air passage at the front end of the air outlet 13. The limiting shell 25 rotates outside one end of the filter disc 24 through multiple balls 26. The rotating blade 27 is made of stainless steel sheet, and the soft brush 28 with the upper edge is made of nylon material and fits against the outer periphery of one side of the filter disc 24.

[0048] Specifically, the filter disc 24 acts as the first protective barrier, preventing material particles from entering the air outlet 13 and avoiding airway blockage. When dry gas is ejected from the air outlet 13, the airflow acts on the vane 27, driving the movable shell 14 to rotate around the filter disc 24. The ball bearings 26 in the limiting shell 25 reduce rotational friction, ensuring smooth rotation of the movable shell 14. When the movable shell 14 rotates, the soft brush 28 rotates synchronously, continuously cleaning the material particles adhering to the outer periphery of the filter disc 24 outlet, achieving a self-cleaning function. The pores on the movable shell 14 ensure that the gas can be evenly dispersed into the material, ensuring unobstructed airway without affecting the dehumidification and anti-caking effect.

[0049] It should be noted that during the process of the movable shell 14 rotating and interlacing with the material, the rotational connection will also produce a rotational effect.

[0050] A method for using a material buffer device suitable for the production of polyvinyl chloride paste resin, comprising the following steps:

[0051] S1: Put the polyvinyl chloride paste resin material into the buffer tank 2, so that the material feeding cylinder 11 is buried inside the material;

[0052] S2: Dry gas is introduced into the material cylinder 11 through the air inlet pipe 21, rotary joint 5 and air storage plate 8. The gas is dispersed into the material through the air outlet 13 and its protective components to prevent the material from clumping and absorbing moisture.

[0053] S3: Start the drive mechanism to drive the rotating shaft 9 to rotate, causing the feeding cylinder 11 to rotate and stir in the material. At the same time, the spiral blades 12 rotate to promote the material to turn over inside the buffer tank 2, while the resistance-reducing component disturbs the material flow. The low-temperature flexible heat conduction tape 18 heats the material synchronously with the rotation of the feeding cylinder 11.

[0054] S4: The processed material falls through the discharge passage and is then discharged from the buffer tank 2 via the screw conveyor auger 3.

[0055] Working Principle: First, polyvinyl chloride paste resin material is added to the buffer tank 2 until it submerges the material penetration cylinder 11. After the device is started, dry gas supplied by an external air source is continuously introduced into the rotating shaft 9 through the air inlet pipe 21 and the rotary joint 5. Thus, when the motor 4 starts, it can drive the shaft 9 to rotate at a low speed in the buffer tank 2. When the shaft 9 rotates, the connecting cylinder shell 23 and the gas storage plate 8, which are fixedly connected to it, rotate synchronously. The dry gas enters the inner cavity of the gas storage plate 8 through the through pipe 22 inside the connecting cylinder shell 23, and is then distributed to the two connecting rods 20 through the J-shaped rigid pipes 17 on both sides of the gas storage plate 8. The gas finally flows into the material penetration cylinder 11 and is ejected from multiple air outlets 13 distributed on the cylinder wall of the material penetration cylinder 11. Because the material penetration cylinder 11 is deeply buried in the material and rotates with the shaft 9, the dry gas can be released evenly and dynamically from multiple points inside the material pile. This process can effectively replace the moisture between particles, thereby inhibiting the surface adhesion and agglomeration tendency of PVC paste resin microparticles due to moisture absorption from the root, and achieving active anti-caking.

[0056] When the shaft 9 rotates, the spiral blades 12 rotate synchronously, mainly pushing the material at the bottom of the buffer tank 2 axially, promoting the material to move upwards. Simultaneously, the material-passing V-plate 10 fixed to the material-passing cylinder 11 cuts, tumbles, and disturbs the material as it rotates through the cylinder, further disrupting the bonding structure between particles and reducing the resistance of the rotating cylinder 11. This, combined with the low-temperature flexible heat-conducting tape 18 on the cylinder 11, provides uniform low-temperature heat conduction to the material during rotation, helping to reduce localized humidity, improve fluidity, and prevent degradation due to localized overheating. The pushing action of the spiral blades 12, the disturbance of the resistance-reducing components, and the drying effect of the low-temperature flexible heat-conducting tape 18 work together to ensure the material is in a loose, uniform fluidized state, effectively preventing bridging and rat-hole formation.

[0057] A protective component is installed on the outside of the filter disc 24, mainly to prevent material backflow and blockage of the air passage. The gas drives the vane 27 inside the movable shell 14 to rotate, which drives the soft brush 28 to sweep across the outer periphery of the air outlet 13, achieving self-cleaning. During operation, the four vibrating support rods 7 installed on the movable frame 1 can intermittently or continuously generate micro-vibrations. This vibration is transmitted to the buffer tank 2, helping to overcome the friction and adhesion between the material and the tank wall, and promoting the smooth downward flow of the material.

[0058] During discharge, the processed loose material finally falls through the discharge passage between the spiral blade 12 and the tank wall, and is output in a controllable and stable manner by the spiral conveyor auger 3 at the bottom of the buffer tank 2, completing the buffer turnover process.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
