Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic processing, specifically relates to a modified plastic homogenization and dust removal equipment. BACKGROUND

[0002] Modified plastics are produced by adding various modifiers, such as flame retardants, reinforcing materials, stabilizers, etc., to the base resin to improve the performance of plastics and meet specific application requirements. These modified plastics are widely used in the automotive, electronics, construction and packaging industries. In the production process of modified plastics, homogenization and dust removal are two key steps that directly affect the quality of the final product.

[0003] Traditional modified plastic homogenization equipment usually uses simple stirring or tumbling mechanisms to achieve particle mixing. These methods have the problems of low homogenization efficiency and uneven mixing. In addition, some current equipment performs dust removal during the modified plastic homogenization process, but the dust removal effect is not good. For example, the Chinese patent with publication (announcement) number CN219634244U discloses a modified plastic homogenization and dust removal equipment. This scheme lifts the modified plastic through spiral blades, and the modified plastic is allowed to fall freely from the top end of the spiral blades to achieve the homogenization process. The homogenization effect is not good, and the debris mixed into the modified plastic particles is removed by blowing. However, the top of the homogenization tank is flat, and the dust will stick to the top side of the homogenization tank, making it difficult to smoothly discharge from the debris outlet.

[0004] To solve the above problems, the present application provides a modified plastic homogenization and dust removal equipment. INVENTION CONTENTS

[0029] A modified plastic homogenization and dust removal equipment mainly comprises a mounting frame 1, a homogenization tank 2 and a lifting mechanism 3, wherein:

[0030] The implementation of the scheme is that the homogenization tank 2 is installed at the top of the mounting frame 1 to realize stable support of the equipment, and the smooth entry and exit of the modified plastic particles is realized through the feeding port 21 and the discharging port 22 arranged on the homogenization tank 2, the top end of the homogenization tank 2 is fixedly connected with a conical dust guide cylinder 23, the top end of the dust guide cylinder 23 has a smaller diameter and is connected with a dust discharge pipe 24, the process of dust removal and dust discharge is optimized, the homogenization tank 2 is connected with a blowing pipe 25, the design of the conical dust guide cylinder 23 helps to concentrate the collection and effectively discharge the dust, avoids the accumulation of dust on the top of the homogenization tank 2, and improves the dust removal efficiency, and it should be noted that the blowing pipe 25 is connected with the existing blowing equipment outside, and the dust discharge pipe 24 is connected with the existing dust recovery equipment outside;

[0031] The lifting mechanism 3 is arranged in the interior of the homogenization tank 2, the lifting mechanism 3 comprises a lifting assembly 31 for lifting part of the modified plastic to a certain height and then freely falling and a stirring assembly 32 for stirring the modified material, and the synergistic effect of the lifting assembly 31 and the stirring assembly 32 improves the homogenization efficiency and mixing uniformity of the material, and solves the problems of low efficiency and uneven mixing of the traditional homogenization equipment.

[0032] In operation, the modified plastic particles enter the homogenization tank 2 through the feeding port 21, the lifting assembly 31 in the interior of the lifting mechanism 3 lifts the material to a certain height, and then the material freely falls to increase the mixing opportunity of the material and realize preliminary homogenization, then the stirring assembly 32 deeply stirs the material to ensure the uniform mixing of the material, the blowing pipe 25 generates airflow, the material freely falls to carry away the dust and debris, and the dust and debris are discharged through the conical dust guide cylinder 23 to complete the dust removal process.

[0033] The design and implementation of the lifting assembly 31 is to efficiently lift and homogenize the modified plastic particles, please refer to Figure 2 、 Figure 3 and Figure 4 , the lifting assembly 31 includes a lifting cylinder 311 vertically arranged inside the homogenizing tank 2 and located on the central axis of the homogenizing tank 2, which ensures the symmetry and uniform distribution of the material during lifting, the outer side of the lifting cylinder 311 is fixedly connected with a support rod 312 on the bottom wall of the homogenizing tank 2, which provides necessary structural stability, the two ends of the lifting cylinder 311 are communicated and the bottom end is not in contact with the bottom wall of the homogenizing tank 2, which avoids the accumulation of material at the bottom and cannot effectively homogenize, the bottom wall of the homogenizing tank 2 is rotatably installed with a rotating rod 313 penetrating the lifting cylinder 311, the rotating rod 313 is fixedly sleeved with a spiral blade 314, and the bottom of the mounting frame 1 is fixed with a motor 315 whose output end is fixed with the bottom end of the rotating rod 313;

[0034] In terms of operation, the spiral blade 314 is rotated by the driving of the motor 315, realizing the continuous lifting of the modified plastic particles, and when the material is lifted to above the top end of the lifting cylinder 311, the material will be scattered from the top end of the lifting cylinder 311 due to gravity, increasing the mixing opportunity of the material and improving the homogenization efficiency.

[0035] Further, the operation mode of the stirring assembly 32 is to work cooperatively with the lifting assembly 31, please refer to Figure 2 、 Figure 3 and Figure 4 , the stirring assembly 32 includes a connecting block 321 fixed on the top end of the rotating rod 313, a plurality of L-shaped stirring rods 322 are fixedly arranged on the outer circumferential side of the connecting block 321, and a plurality of stirring blades 323 are fixedly arranged on the L-shaped stirring rods 322, which are uniformly distributed, the stirring blades 323 are rotated under the rotation of the rotating rod 313, and the material is deeply stirred, which not only enhances the mixing effect of the material, but also ensures that the material inside the homogenizing tank 2 can be effectively stirred through the uniform distribution of the L-shaped stirring rods 322.

[0036] In this embodiment, please refer to Figure 4 , a conical flow guide plate one 316 is fixed on the outer side of the top end of the lifting cylinder 311, the diameter of the bottom end of the flow guide plate one 316 is larger, which helps to form a material dispersion area at the top end of the lifting cylinder 311, so that the material can be uniformly dispersed and falls after being lifted to the highest point, increasing the contact area of the material and air, and providing more favorable conditions for homogenization and dust removal process;

[0037] Operation, when the material is lifted to the top of the lifting cylinder 311 with the spiral blade 314, the conical structure of the guide plate 316 guides the material to diffuse outward. Because the bottom diameter is larger, the flow of the material here is smoother, reducing the accumulation of the material at the top of the lifting cylinder 311, avoiding the problem of channel blockage caused by the accumulation of the material.

[0038] It should be noted that, please refer to Figure 4 , the lifting cylinder 311 is fixed with a conical guide plate 317, the guide plate 317 is symmetrically arranged with the guide plate 316 and fixed at the end with a larger opening. The guide plate 317 has the advantage of effectively guiding the airflow blown out of the air blowing pipe 25 and better dust removal.

[0039] Please refer to Figure 2 , the direction of the airflow blown into the homogenizing tank 2 by the air blowing pipe 25 is inclined upward, and the end of the air blowing pipe 25 connected with the homogenizing tank 2 is lower than the guide plate 317. This design enables the airflow to effectively contact the material, and the upward airflow facilitates the dust to be guided to the dust discharge pipe 24 for discharge. At the same time, the end of the air blowing pipe 25 connected with the homogenizing tank 2 is lower than the guide plate 317, which ensures the reasonable distribution of the airflow and avoids interference with the normal flow of the material in the lifting cylinder 311.

[0040] Beneficially, please refer to Figure 2 and Figure 3 , the inner wall of the dust guide cylinder 23 is fixed with a filter plate 231. This design is to further improve the collection efficiency of dust during the dust removal process in the embodiment, realize the function of intercepting modified plastics, and avoid the waste of materials.

[0042] I. First, check whether all parts of the modified plastic homogenizing and dust removal equipment are normal, including the mounting frame 1, the homogenizing tank 2, the lifting mechanism 3, the feed inlet 21, the discharge outlet 22, the dust guide cylinder 23, the dust discharge pipe 24, the air blowing pipe 25, etc. Ensure that there is no damage or looseness;

[0043] II. Start the motor 315 at the bottom of the mounting frame 1, rotate the spiral blade 314 through the rotating rod 313, and connect the air blowing pipe 25 with the external air blowing equipment to blow air into the homogenizing tank 2;

[0044] III. Open the feed inlet 21, and add the modified plastic particles that need to be homogenized into the homogenizing tank 2 through the feed inlet 21;

[0045] Four, with the driving of the motor 315, the spiral blade 314 inside the lifting cylinder 311 lifts the material upwards, at the same time, the guide plate 316 at the top end of the lifting cylinder 311 guides the material to fall and disperse, realizing preliminary mixing, and in the process of falling, the dust is blown to the dust guide cylinder 23 and guided to the dust discharge pipe 24 to be discharged;

[0046] Five, in the process of falling, the material is further mixed and uniformed by the action of the L-shaped stirring rod 322 and the stirring blade 323;

[0047] Six, after the homogenization and dust removal are completed, the discharge port 22 is opened, and the homogenized modified plastic particles are discharged from the homogenizing tank 2.
