Description

Technical Field

[0001] The present invention relates to the technical field of plastic particle cooling, and particularly to a modified plastic particle circulating cooling device. Background Art

[0002] Modified plastic particles are plastic products obtained by processing and modifying general plastics and engineering plastics through methods such as filling, blending, and reinforcement, improving their properties in aspects such as flame retardancy, strength, impact resistance, and toughness. Modified plastic particles are made by adding functional auxiliaries, additives, fillers, etc. to plastics, or by blending different polymers, through physical or chemical methods, to form modified plastic polymers that meet certain requirements. The technologies of modified plastics mainly include blending, filling, toughening, strengthening, compatibilization, flame retardancy, alloying, etc., to improve the characteristics of resins in aspects such as flame retardancy, aging resistance, mechanical properties, and electrical, magnetic, optical, and thermal properties.

[0003] Modified plastic particles are widely used in fields such as automobiles, electronics, and packaging in industrial production. During their production process, they need to go through steps such as high-temperature melting and extrusion molding. The temperature of the formed plastic particles is relatively high. If not cooled in time, it is easy to cause particle adhesion and deformation, affecting subsequent processing performance. Therefore, an efficient and uniform cooling device is one of the key equipment for the production of modified plastic particles. Traditional cooling processes mostly use natural air cooling or water cooling systems, but there are problems such as low cooling efficiency, high energy consumption, and uneven particle distribution. With the increase in the types of modified plastics and the expansion of production scale, higher requirements are put forward for the intelligence and circulation of cooling devices.

[0004] In the prior art, common cooling devices mostly use a straight conveyor belt in combination with a fan for cooling, and their defects are significant: First, the space utilization rate of the straight conveyor belt is low, the cooling path is short, and multiple cycles are required to achieve an ideal cooling effect, resulting in a large floor area of the equipment; Second, single-point fan air supply easily causes uneven air flow distribution and large differences in the surface cooling rate of particles, affecting the uniformity of the finished product; In addition, traditional devices lack an effective vibration dispersion mechanism, and high-temperature particles are prone to agglomeration during transportation, requiring manual intervention and increasing production costs. Some improvement schemes attempt to introduce a spiral conveying structure, but the problems of coordinated operation of vibration and cooling are not solved, and there is a lack of an automatic impurity separation function, resulting in the need for secondary screening of the particles after cooling. Therefore, there is an urgent need for an integrated device that integrates vibration dispersion, circulating cooling, and automatic screening to improve the cooling efficiency and quality of modified plastic particles. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a modified plastic particle circulating cooling device, which overcomes the deficiencies of the prior art and effectively solves the problems of short cooling path, uneven air flow distribution, and the need for secondary screening.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A modified plastic particle circulating cooling device includes a frame. A vibration assembly is provided on the outer wall of the top of the frame, and a cooling assembly is provided on the outer wall of the vibration assembly. The vibration assembly includes springs that are fixedly connected to the outer wall of the top of the frame and are distributed in an array. The top outer wall of the spring is fixedly connected to a base, and a hollow column is welded to the top outer wall of the base. A top seat is welded to the top outer wall of the hollow column, and symmetrically distributed vibration motors are fixedly connected to the inclined surface of the top seat by screws. The rotation directions of the two vibration motors are opposite, and the two vibration motors are arranged opposite to each other. A spiral conveying groove is welded to the outer wall of the hollow column;

[0008] Through the above solution, vibration and spiral conveying are used in combination to improve the cooling efficiency. In this device, the symmetrically arranged vibration motors generate a reverse rotational force to drive the high-frequency vibration of the hollow column and the spiral conveying groove. During the vibration process, the plastic particles continuously tumble in the spiral conveying groove and rise along the spiral path. While extending the cooling path, the particle gaps increase, and the heat dissipation area is significantly increased. Combined with the connecting rods on the outer wall of the spiral conveying groove, particle accumulation is further prevented, ensuring uniform dispersion. This design effectively improves the cooling efficiency compared with the traditional linear conveyor belt cooling method.

[0009] The cooling assembly includes heat dissipation holes opened on the outer wall of the hollow column. One side of the bottom of the outer wall of the hollow column is fixedly connected to an exhaust pipe through a flange, and a blower is installed on the outer wall of one end of the exhaust pipe. An air suction pipe is installed on the inner wall of the air inlet of the blower. The other side of the bottom of the outer wall of the hollow column is fixedly connected to a plastic dispersion air pipe, and air blowing nozzles are arranged on the outer wall of one end of the plastic dispersion air pipe at equal distances.

[0010] Through the above solution, a multi-stage air flow circulation system is adopted to optimize heat dissipation. In the cooling assembly, the blower inhales external air through the air suction pipe and introduces it into the interior of the hollow column through the exhaust pipe. The air uniformly overflows from the heat dissipation holes to form an annular air flow layer surrounding the spiral conveying groove, realizing rapid cooling of the particle surface. At the same time, the air blowing nozzles at the bottom of the plastic dispersion air pipe jet air flow to push the particles apart, avoiding adhesion between particles and between particles and the groove wall. This dual air flow system forms a dynamic cycle, improving the heat dissipation efficiency compared with single-point air supply.

[0011] Preferably, a feeding box is welded to the outer wall of one end of the air blowing nozzle, and a cover plate is hinged to the top outer wall of the feeding box. The feeding box is welded to the bottom outer wall of the spiral conveying groove, and a feeding port is provided at the connection between the feeding box and the spiral conveying groove.

[0012] Preferably, a blanking box is welded to the outer wall of the top end of the spiral conveying trough, and a screen is arranged on the outer wall of the bottom of the blanking box. The screen is made of stainless steel. A discharge frame is fixedly connected to the bottom outer wall of the blanking box at the bottom of the screen through screws. A discharge pipe is fixedly connected to the bottom outer wall of the discharge frame, and a discharge head with a handle is installed on the outer wall of one end of the discharge pipe.

[0013] Preferably, a waste discharge hopper is fixedly connected to one side of the discharge frame on the bottom outer wall of the blanking box, and a waste discharge pipe is fixedly connected to the bottom outer wall of the waste discharge hopper. A waste discharge head with a handle is installed on the outer wall of one end of the waste discharge pipe.

[0014] Preferably, the functions of integrated screening and impurity separation are realized. A stainless steel screen is arranged at the bottom of the blanking box. The cooled particles fall into the discharge frame after being filtered by the screen and are centrally discharged through the discharge pipe; the unqualified particles and impurities enter the waste discharge hopper through the waste discharge outlet and are automatically separated by the waste discharge pipe. This design eliminates the subsequent manual screening step and improves the qualified rate of the finished product.

[0015] Preferably, a discharge port is arranged at the connection between the blanking box and the spiral conveying trough, and a waste discharge outlet is arranged at the connection between the blanking box and the waste discharge hopper.

[0016] Preferably, an aggregate hopper is welded to the bottom of the outer wall of the hollow column, and the cross-sectional area of the aggregate hopper is larger than that of the spiral conveying trough.

[0017] Preferably, circumferentially distributed connecting rods are installed on the outer wall of the spiral conveying trough.

[0018] Preferably, a support frame is welded to the outer wall of the top of the frame, and both the discharge pipe and the waste discharge pipe are placed on the outer wall of the top of the support frame. An electric control cabinet is installed on the outer wall of the top of the frame, and the electric control cabinet is connected to the vibration motor and the blower through signal lines. The electric control cabinet is used to adjust the vibration frequency of the vibration motor and the rotation speed of the blower.

[0019] The vibration assembly is composed of springs, a base, a hollow column, a top seat and a vibration motor at the top of the frame. The springs are arranged in an array, effectively buffering the vibration impact and ensuring the stability of the equipment. The vibration motors are symmetrically and obliquely installed on the top seat, and reverse rotation generates horizontal and vertical composite vibrations, driving the particles in the spiral conveying trough to rise spirally. The hollow column also serves as an air flow channel, and the spiral conveying trough welded to its outer wall is made of 304 stainless steel, which is wear-resistant and has excellent heat conductivity.

[0020] The cooling assembly includes heat dissipation holes, an exhaust pipe, a blower and a plastic dispersion air pipe. The heat dissipation holes are evenly opened along the circumference of the hollow column, with a hole diameter of 3 mm and a pitch of 50 mm, ensuring that the air flow evenly covers the surface of the particles. The power of the blower is 2.2 kW, and the maximum air volume is 2000 m 3 / h, the exhaust pipe connected by a flange guides the airflow into the hollow column. The plastic dispersion air pipe is arranged at the bottom of the hollow column 4, and its air blowing nozzles are distributed at intervals of 100 mm each, forming a forward jet airflow to enhance the particle dispersion effect.

[0021] The feeding box is welded to the bottom end of the spiral conveying trough, and the cover plate is hinged at the top for convenient manual or mechanical feeding. The particles enter the spiral conveying trough through the feeding port, are vibrated and conveyed to the top and then fall into the discharging box. The qualified particles are discharged through the discharge pipe, while the impurities enter the impurity discharge hopper through the waste discharge port. Both the discharge head and the impurity discharge head are equipped with handles for convenient and quick disassembly and cleaning.

[0022] The aggregate hopper is welded to the bottom of the hollow column, and its cross-sectional area is 1.5 times that of the spiral trough, which can collect the plastic particles falling from the spiral conveying trough during vibration, avoiding waste of raw materials. The support frame is welded by angle steel with a load-bearing capacity of 500 kg to ensure the stability of the discharge pipe and the impurity discharge pipe. The electric control cabinet is internally equipped with a PLC controller, supports touch screen operation, and can preset multiple cooling modes.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The modified plastic particle circulating cooling device of the present invention uses vibration and spiral conveying to synergistically improve the cooling efficiency. The device generates a reverse rotation force through symmetrically arranged vibration motors to drive the high-frequency vibration of the hollow column and the spiral conveying trough. During the vibration process, the plastic particles continuously roll in the spiral conveying trough and rise along the spiral path, extending the cooling path while increasing the particle gap and significantly enhancing the heat dissipation area. Combining with the connecting rods on the outer wall of the spiral conveying trough further prevents particle accumulation and ensures uniform dispersion. This design effectively improves the cooling efficiency compared with the traditional linear conveyor belt cooling method;

[0025] 2. The modified plastic particle circulating cooling device of the present invention uses a multi-stage air circulation system to optimize heat dissipation. In the cooling component, the blower inhales external air through the suction pipe and introduces it into the hollow column through the exhaust pipe. The air evenly overflows from the heat dissipation holes, forming an annular airflow layer surrounding the spiral conveying trough to quickly cool the particle surface. At the same time, the air blowing nozzles at the bottom of the plastic dispersion air pipe jet airflow to push the particles apart, avoiding adhesion between particles and between particles and the trough wall. This double-airflow system forms a dynamic cycle, improving the heat dissipation efficiency compared with single-point air supply;

[0026] 3. The modified plastic particle circulating cooling device of the present invention integrates the functions of screening and impurity separation. A stainless steel screen is set at the bottom of the discharging box. The cooled particles are filtered by the screen and fall into the discharge frame and are centrally discharged through the discharge pipe; the unqualified particles and impurities enter the impurity discharge hopper through the waste discharge port and are automatically separated by the impurity discharge pipe. This design eliminates the subsequent manual screening step and improves the finished product qualification rate. Description of the Drawings
