Description

Technical Field

[0001] This utility model relates to a modification treatment device, and more particularly to a surface modification treatment device for plastic particles. Background Technology

[0002] In the field of plastics processing, surface modification of plastic granules is a crucial step in improving their performance. Modification can enhance the compatibility, dispersibility, or functionality of the granules to meet the quality requirements of different downstream products. Traditional surface modification of plastic granules typically requires batching materials into a closed container and relying on methods such as stirring or spraying to bring the modifier into contact with the granules. This container-based batch processing flow has been used in industrial production for many years.

[0003] However, when granules are stacked in a closed container, the inner and outer layers of material have uneven contact with the modifier. Friction on the container wall can also cause damage to the surface of some granules or deviation in the distribution of the modifier. This problem of uneven modification caused by batch stacking is particularly prominent when processing high-filling or fine-modification requirements, directly affecting the performance stability of subsequent products. There is an urgent need for a device that can fully disperse and uniformly contact the modifier with plastic granules during the processing to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] A device for surface modification treatment of plastic particles, such as Figure 1-4 As shown, the equipment includes a frame 1, a material discharge frame 2, a second frame 3, a first transmission line 31, a first heater 4, a wind box 5, an air inlet pipe 51, a guide plate 52, a second transmission line 6, a liquid inlet pipe 61, an atomizing nozzle 62, and a partition plate 63. The material discharge frame 2, vertically inserted on the left side of the first frame 1, is fixedly connected to the first frame 1 by welding. The material discharge channel inside the first frame 2 is vertically continuous. A discharge port is opened at the bottom of the first frame 2. The lower part of the first frame 2 is funnel-shaped, gradually narrowing towards the discharge port. Material entering the lower part of the first frame 2 will... The material falls rapidly under its own weight and the action of the inclined surface, preventing the material from accumulating at the discharge port. Equipment frame 2 3 is installed on the left side of equipment frame 1 via a bracket. Conveyor line 31 is installed inside equipment frame 2 3 and is fixed to the inner wall of equipment frame 2 3 by bearing seats. Heater 4 is installed on equipment frame 2 3. The heating element of heater 1 extends into the interior of equipment frame 2 3. When the material passes through conveyor line 31, heater 4 preheats the material, raising the material temperature to a state suitable for subsequent processing, thereby improving the plasticity and processing performance of the material.

[0024] The upper left part of the second equipment frame 3 has a feed port for connecting with the external feeding mechanism to facilitate the entry of materials into the second equipment frame 3. The right side of the second equipment frame 3 is fixed to the top of the dropping frame 2 through a flange connection to ensure that the materials can smoothly enter the dropping frame 2 from the second equipment frame 3. The lower right part of the second equipment frame 3 has a conveyor port, which is aligned with the top opening of the dropping frame 2. The right side of the first transmission line 31 extends to the space above the dropping channel. When the first transmission line 31 is running, it can send the preheated materials from the conveyor port into the dropping channel of the dropping frame 2, so that the materials fall vertically.

[0025] A bellows 5 is installed on the left side of the equipment frame 1. The bellows 5 is fixed to the inner wall of the equipment frame 1 by bolts. An air inlet pipe 51 is connected to the left side of the bellows 5. The air inlet pipe 51 connected to the left side of the bellows 5 is connected to an external fan. The airflow generated by the fan enters the bellows 5 through the air inlet pipe 51 and is then blown out to the upper right from the air outlet on the upper right side of the bellows 5. The air outlet is located below the discharge port of the material discharge frame 2. Two guide plates 52 are set on the left side of the equipment frame 1 and fixed to the inner wall of the equipment frame 1 by welding. When the material falls from the material discharge frame 2 into the equipment frame 1, it will be carried by the airflow blown out of the air outlet. The guide channel separated by the two guide plates 52 guides the airflow and material, so that the material is suspended and thrown towards the transmission line 2 6 along the guide channel, making the material more evenly dispersed during the movement.

[0026] The second transmission line 6 is inclinedly set in the left space of the guide plate 52 inside the first equipment frame 1. It is fixed to the inner wall of the first equipment frame 1 by a bracket. The whole is in a state of right high and left low. After the material is thrown onto the second transmission line 6, it can move to the left along the second transmission line 6 under the action of gravity. An installation groove is opened on one side inner wall of the dropping frame 2. A partition 63 is fixed in the installation groove by a slot to separate the installation groove from the dropping channel inside the dropping frame 2.

[0027] Liquid inlet pipes 61 are installed on the front and rear sides of the upper part of the equipment frame 1 and in the mounting groove of the material discharge frame 2. They are fixed to the equipment frame 1 and the material discharge frame 2 by pipe clamps. Several atomizing nozzles 62 are threadedly connected to the liquid inlet pipes 61 at intervals. The liquid inlet pipes 61 are used to connect to external modified liquids. A flow regulating valve installed at the liquid inlet end of the liquid inlet pipes 61 can control the flow rate of the modifier. The atomizing nozzles 62 in the mounting groove extend into the material discharge channel through the partition 63. When the modifier enters the atomizing nozzles 62 through the liquid inlet pipes 61, it is atomized into fine particles under pressure. As the material falls... In the first stage, the atomizing nozzle 62 in the material drop frame 2 atomizes the modifier and sprays it onto the material, so that the modifier initially coats the surface of the material. When the material enters the equipment frame 1 and is blown to the right by the airflow from the outlet and enters the space where the transmission line 2 6 is located, the atomizing nozzle 62 in the equipment frame 1 sprays out the modifier to fill the equipment frame 1 and coat the material again. Since the material moves in a suspended state in the equipment frame 1, the modifier can coat the material evenly from all directions, thereby improving the uniformity of the coating and forming a more uniform and firm coating layer on the surface of the material, thus improving the performance and quality of the material.

[0028] like Figure 1 and Figure 5As shown, it also includes a drying chamber 7, a partition 71, a third transmission line 72, and a second heater 73. A material transfer port is located on the right side of the equipment frame 1, and a partition 71 is installed at the material transfer port. The material transfer port on the right side of the equipment frame 1 is fixedly connected to the partition 71 by bolts. The right end of the partition 71 is fixed to the drying chamber 7 by a flange connection, ensuring the airtightness between the equipment frame 1 and the drying chamber 7 and preventing airflow and material leakage during material transfer. The third transmission line 72 is horizontally mounted inside the drying chamber 7, and its mounting frame is fixed to both sides of the inner wall of the drying chamber 7 by bolts. The structure of the third transmission line 72 is the same as that of the first transmission line 31 and the second transmission line 6, all consisting of a mounting frame, a rotating roller mounted on both sides of the mounting frame, and a conveyor belt wound around the outside of the two rotating rollers. The conveyor belts are composed of three separate conveyor belts, with the third conveyor belt 72 driven by an independent motor. The left part of the third conveyor belt 72 passes through the partition 71 to the left and extends into the right part of the equipment frame 1. Its left part is located in the space below the right part of the second conveyor belt 6. When the material moves to the end of the second conveyor belt 6 to the left, it will fall onto the conveyor belt of the third conveyor belt 72 under the action of gravity. The third conveyor belt 72 then feeds the material into the drying chamber 7. The second heater 73 installed in the drying chamber 7 is fixed to the inner wall of the drying chamber 7 by a bracket, and its heating element faces the third conveyor belt 72. The conveyor belts of the first conveyor belt 31, the second conveyor belt 6, and the third conveyor belt 72 are all hollow. This hollow structure is composed of regularly arranged through holes, which can not only support the smooth transmission of materials, but also allow the modifier mist and heat flow to pass through freely.

[0029] Among them, heater 1 4 and heater 2 73 are both microwave heaters. Heater 1 4 and heater 2 73 can generate heat by causing polar molecules in the material to vibrate at high frequency through microwaves.

[0030] Heater 2 73 heats and dries the material on transmission line 3 72, rapidly evaporating the liquid solvent in the modifier, allowing the modifier to adhere more firmly to the material surface and improving the coating effect.

[0031] In addition, such as Figure 1 and Figure 5As shown, it also includes a turbo fan 8, an air collector 81, and a guide pipe 82. Multiple turbo fans 8 are installed at the bottom of the drying chamber 7, and the turbo fans 8 are fixed to the bottom of the drying chamber 7 with bolts. A hot air inlet pipe is connected to the air inlet of the turbo fan 8, and the hot air inlet pipe is connected to an external heat source (such as a heating device). The air outlet of the turbo fan 8 is connected to the internal space of the drying chamber 7. When the turbo fan 8 is working, it draws in the hot air from the hot air inlet pipe and blows it into the lower part of the drying chamber 7, forming a circulating hot airflow. Multiple air collectors 81 installed at the top of the drying chamber 7 are fixed to the top of the drying chamber 7 by brackets, and the air collectors 81 are connected to each other through the guide pipe 82. The guide pipe 82 guides the hot air collected by each air collector 81 to a specific location (such as exhaust to the outside or recycling). The turbo fan 8 blows the hot air into the drying chamber 7, where it works together with the heat generated by the heater 73. At the same time, the continuous exhaust flow from the air collector 81 creates an upward airflow inside the drying chamber 7, ensuring a uniform temperature distribution. This assists the drying process of the heater 73, accelerates the evaporation of the liquid solvent in the modifier, shortens the drying time, improves production efficiency, and ensures uniform drying of the material, avoiding incomplete or excessive drying in certain areas.

[0032] like Figure 2 As shown, a guide frame 9 is provided on the right side of the equipment frame 1, which is fixed to the inner wall of the equipment frame 1 by bolts. The guide frame 9 is located in the area between the right side of the second transmission line 6 and the left side of the third transmission line 72. The guide frame 9 is inclined on the left and right, and the inclination angle facilitates the material to slide to the right under the action of gravity. Several material distribution blocks are arranged at intervals on the right side of the guide frame 9. The material distribution blocks are welded and fixed to the inner wall of the guide frame 9. Multiple parallel material guiding channels are divided in the right side of the guide frame 9 by the multiple material distribution blocks. A vibration module 91 is installed on the guide frame 9 and is fixed to the guide frame 9 by bolts. On the outside, its vibrating end is rigidly connected to the guide frame 9. The vibration energy of the vibration module 91 is transmitted to the entire guide frame 9 without loss through the rigid connection structure, causing the guide frame 9 to vibrate regularly. This vibration acts on the material accumulated in the guide frame 9, destroying the friction and adhesion between the material particles, and causing the originally agglomerated material to disperse under the action of vibration inertial force. At the same time, in conjunction with the tilt angle of the guide frame 9 and the guide channel formed by the material distribution block, the material can be evenly dispersed and fall, effectively avoiding the accumulation of a large amount of material on the conveyor belt of the transmission line 72, and ensuring that the material enters the subsequent drying process in a loose and uniform state.

[0033] In a preferred embodiment: such as Figure 2 and Figure 4 As shown, a baffle 53 is provided at the air outlet of the air box 5. The baffle 53 is fixed to the edge of the air outlet by a slot. The shape and size of its mesh are designed to ensure that the airflow can be discharged smoothly and to intercept particles that accidentally deviate during the fall, so as to prevent them from falling into the air box 5 and blocking the air duct or damaging the internal structure.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
