A thermoplastic polyvinyl chloride (PVC) environmentally friendly internal mixing device

Abstract

This utility model discloses a mixing device for producing environmentally friendly thermoplastic polyvinyl chloride (PVC), including a support frame mounted on a main body and a mixing chamber installed within the support frame. A geared motor is mounted on the side of the support frame at the top of the main body, and the output end of the geared motor is connected to the inside of the mixing chamber. A protective cover is mounted on the top of the mixing chamber, and a hydraulic device is mounted on the top of the protective cover. A sealing cap is mounted on the bottom of the protective cover. Through the designed sealing mechanism, the problem of the sealing material and size being incompatible with the working environment of the mixing chamber during the production of environmentally friendly thermoplastic polyvinyl chloride (PVC) is improved.

[0002] In the production and processing of thermoplastic polyvinyl chloride (PVC), environmentally friendly PVC requires a variety of raw materials. The equipment uses rotor stirring and shearing to ensure that the raw materials are fully mixed, avoiding uneven local composition that could affect product performance. For example, poor dispersion of stabilizers can reduce the heat resistance of PVC.

[0003] In the existing thermoplastic polyvinyl chloride (PVC) environmentally friendly production process, when using the mixing device, the working environment of the mixing chamber is high temperature and high pressure. The material and size of the sealing parts are not compatible with the working environment of the mixing chamber, which easily leads to material aging and deformation. As a result, the sealing parts cannot fit tightly after installation, causing leakage problems. Therefore, this utility model proposes a thermoplastic polyvinyl chloride environmentally friendly PVC production mixing device. Utility Model Content

[0019] 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.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a mixing device for producing environmentally friendly thermoplastic polyvinyl chloride (PVC), including a support frame mounted on a main body 1 and a mixing chamber 3 installed within the support frame. A reduction motor 2 is mounted on the side of the support frame at the top of the main body 1, and the output end of the reduction motor 2 is connected to the inside of the mixing chamber 3. A protective cover 4 is mounted on the top of the mixing chamber 3, and a hydraulic device 5 is mounted on the top of the protective cover 4. A cover 6 is mounted on the bottom of the protective cover 4, and a sealing mechanism is mounted on the inside of the cover 6. The sealing mechanism consists of a sealing component 61, a sealing block 62, and a reinforcing component 63. The sealing component 61 is located inside the cover 6, and the sealing block 62 is fixed inside the cover 6 for reinforcement. Components 63 are all located inside the cover 6 and at the top of the mixing chamber 3. Through the designed sealing mechanism, the problem of mismatched materials and dimensions of the sealing components used in the production of environmentally friendly thermoplastic polyvinyl chloride (PVC) during the mixing chamber, leading to aging and failure to achieve a sealing effect, is improved. The sealing mechanism uses polytetrafluoroethylene (PTFE) composite materials for both the sealing gasket and the sealing sleeve, which are temperature-resistant, wear-resistant, and chemically resistant, matching the high-temperature and additive-containing environment of the mixing chamber. Furthermore, the sealing gasket 611 can be disassembled and replaced as needed, increasing flexibility. The sealing component 61 consists of the sealing gasket 611, the base 612, and symmetrically arranged limiting components 613. The base 612... The limiting components 613, symmetrically arranged, are located on the inner side of the cover 6 and at the connection between the outer side of the base 612 and the inner wall of the cover 6. The sealing gasket 611 is fixed to the inner side of the base 612. When the material enters the interior of the mixing chamber 3, the hydraulic device 5 drives the cover 6 to press down, sealing the top opening of the mixing chamber 3. The bottom edge of the sealing gasket 611 is inclined to guide the material, sealing the side of the mixing chamber 3 with the cover 6. During the process of the locking block 631 being inserted into the slot 632, the sealing sleeve 633 is squeezed, sealing the top of the mixing chamber 3 with the inner side of the cover 6. The limiting components 613 consist of the limiting groove 6131, The system consists of a limiting block 6132 and a limiting groove 6131 located inside the cover 6. When the sealing gasket 611 needs to be removed, the through bolts are first removed, and then the sealing gasket 611 is pulled down to separate the base 612 from the cover 6, thus separating the limiting block 6132 from the limiting groove 6131. ​​The limiting block 6132 is located inside the limiting groove 6131 and is fixed to the outside of the base 612. Mounting holes are provided on the inner side of the cover 6 and the inner side of the base 612, and bolts pass through the inner side of the mounting holes. The output end of the hydraulic device 5 is installed on the top of the cover 6. An operation box is provided on the main body 1, and a rotor is provided inside the mixing chamber 3.

[0021] In this embodiment, preferably, the reinforcing component 63 consists of a locking block 631, a locking groove 632, and a sealing sleeve 633. The locking block 631 is fixed to the top of the mixing chamber 3, the locking groove 632 is opened on the inner side of the cover 6, and the sealing sleeve 633 is fixed on the inner side of the locking groove 632. The reinforcing component 63 further seals the joint between the mixing chamber 3 and the cover 6.

[0022] The working principle and usage process of this utility model are as follows: During the processing of thermoplastic polyvinyl chloride (PVC), the relatively rotating rotor in the mixing chamber 3 clamps and carries the thermoplastic PVC and other materials entering from the feeding port into the roller gap. The rotor continuously applies extrusion and shearing force to the material, destroying the original structure of the material and allowing the components to mix fully. At the same time, the temperature is regulated by the temperature control system, so that the material can be plasticized in a suitable temperature environment, achieving a uniform mixing effect and providing high-quality materials for subsequent processing.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
