Description

Technical Field

[0001] This utility model relates to the field of polystyrene processing technology, specifically a polystyrene preparation circulating mixing device. Background Technology

[0002] Polystyrene, a widely used thermoplastic, is chemically a polymer of styrene monomers. A polymer is a large molecule composed of numerous small molecules with identical structures linked by repeated chemical bonds. Styrene monomers are colorless, transparent, and oily liquids with a characteristic odor at room temperature. Through polymerization, they can form polystyrene materials with varying properties. In industrial production, polystyrene is typically prepared by first pre-mixing styrene with various auxiliary additives in a specific formulation ratio, and then adding the mixture to a polymerization reactor. Inside the reactor, by controlling the temperature, pressure, and stirring conditions, the components are ensured to come into full contact and undergo a polymerization reaction, ultimately forming a homogeneous polystyrene product that meets performance requirements.

[0003] However, existing polystyrene mixing processes generally suffer from low mixing efficiency. Specifically, styrene and various additives are mostly fed directly into the reactor in a single batch. Due to the uneven initial distribution of materials and the differences in viscosity, density, and compatibility among components, conventional stirring alone often requires a long time to achieve the desired uniform dispersion, significantly extending the production cycle. Furthermore, additives are usually added from the top of the reactor, requiring gravity and slow diffusion to gradually penetrate the entire material system, especially in high-viscosity media, where this process is even more sluggish. Without an efficient and forced mixing mechanism, simply extending the stirring time to achieve uniformity not only increases energy consumption but also results in low overall mixing efficiency.

[0004] Based on this, a polystyrene preparation recycling mixing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-5 As shown, a polystyrene preparation circulating mixing device includes a mixing tank 11 and a secondary tank 15. The bottom end of the secondary tank 15 is connected to a second discharge pipe, which is installed in an upper mounting hole in the mixing tank 11. An installation shaft 17 is fitted inside the mixing tank 11, with its two ends rotatably mounted at the bottom of the mixing tank 11 and the upper end of the secondary tank 15, respectively. Several first mixing rods are provided on the installation shaft 17 at positions corresponding to the inside of the secondary tank 15. A rotating seat 20 is rotatably mounted at the bottom of the mixing tank 11, with several connecting rods arrayed on the upper end of the rotating seat 20. The other ends of the connecting rods are fixedly connected to the bottom of a transmission pipe 19. A spiral plate 21 is fixedly mounted on the installation shaft 17 at positions corresponding to the inside of the transmission pipe 19. A mixing mechanism for mixing polystyrene material is provided at one end of the transmission pipe 19. A distributing mechanism is provided inside the mixing tank 11 and below the second discharge pipe. The mixing mechanism facilitates the circulating mixing of polystyrene material, and the distributing mechanism facilitates the uniform feeding of ingredients into the mixing tank 11.

[0025] The mixing tank 11 is connected to a first feeding pipe 12 at its upper end and a first discharge pipe 13 at its bottom end. The first discharge pipe 13 is equipped with a solenoid valve 14. The auxiliary tank 15 is connected to a second feeding pipe 16 at its upper end. The end of the second discharge pipe is provided with several first discharge holes. The end of the second discharge pipe is closely attached to a discharge seat 18. The discharge seat 18 is fixedly mounted on a mounting shaft 17. The discharge seat 18 is provided with several second discharge holes arranged in an array. The discharge seat 18 is shaped like a frustum. Several second mixing rods are arranged in an array on the outside of the transmission pipe 19. In use, when it is necessary to prepare polystyrene mixture, the polystyrene raw material is added into the mixing tank 11 through the first feeding pipe 12, and the ingredients are added into the auxiliary tank 15 through the second feeding pipe 16.

[0026] A fixed tube is fixedly provided at the bottom of the rotating seat 20, and a first bevel gear is fixedly provided at the end of the fixed tube. A second bevel gear is fixedly provided at one end of the mounting shaft 17. Both the first and second bevel gears mesh with a third bevel gear. The third bevel gear is fixedly provided at the output end of the motor 26. The motor 26 is fixedly provided at the bottom of the mixing tank 11. When it is necessary to mix the material inside the mixing tank 11, the motor 26 is started. The output end of the motor 26 drives the third bevel gear. The third bevel gear meshes with the first and second bevel gears at the same time, so that the first and second bevel gears drive the transmission pipe 19 and the mounting shaft 17 to rotate respectively. The mounting shaft 17 rotates in the opposite direction to the transmission pipe 19. The mounting shaft 17 drives the discharge seat 18 to rotate. The discharge seat 18 cooperates with the transmission pipe 19 to transport the material at the bottom of the mixing tank 11 to the upper end of the transmission pipe 19. At the same time, the transmission pipe 19 mixes the material inside the mixing tank 11 through the second mixing rod. The mounting shaft 17 drives several first mixing rods to mix the ingredients inside the auxiliary box 15.

[0027] The mixing mechanism includes a connecting box 22, which is installed on the upper end of the transmission pipe 19. The bottom of the connecting box 22 has several third discharge holes. A fixing plate is fixed on the mounting shaft 17 at a position corresponding to the inside of the connecting box 22. Several connecting brackets 23 are arrayed on the fixing plate, and the other end of each connecting bracket 23 is fixedly connected to the upper end of a discharge plate 24. The discharge plate 24 is in close contact with the bottom of the connecting box 22. Several fourth discharge holes are provided on the upper end of the discharge plate 24. Several third mixing rods are provided on the connecting brackets 23. Several fourth mixing rods are provided on the outer side of the transmission pipe 19 at a position corresponding to the inside of the connecting box 22. During use, during installation... When shaft 17 and transmission pipe 19 rotate, mounting shaft 17 drives spiral plate 21 to rotate. Spiral plate 21 and transmission pipe 19 cooperate to transport the material at the bottom of mixing tank 11 to the inside of connecting box 22. At the same time, transmission pipe 19 drives connecting box 22 to rotate. Mounting shaft 17 drives discharge plate 24 to rotate through connecting frame 23. The direction of rotation of connecting box 22 and discharge plate 24 is opposite. After the material at the bottom of mixing tank 11 is discharged into connecting box 22 through one end of transmission pipe 19, the third mixing rod and the fourth mixing rod can mix the material inside connecting box 22. Then, when the third discharge hole and the fourth discharge hole coincide, the material inside connecting box 22 randomly re-enters mixing tank 11.

[0028] The material dispensing mechanism includes a dispensing disc 27, which is positioned above the connecting box 22. A first connecting pipe is fixedly installed in the middle of the dispensing disc 27 and is fixedly installed at the upper end of the connecting box 22. The dispensing disc 27 has several perforations arranged in an array, and several baffles 28 are arranged in an array at the upper end of the dispensing disc 27. A fixing ring is attached to the end of the dispensing disc 27 and is fixedly installed inside the mixing tank 11. In use, when the material in the auxiliary box 15 falls through the first discharge hole to the upper end of the dispensing disc 27, the baffles 28 will prolong the falling time of the material. At the same time, the connecting box 22 drives the dispensing disc 27 to rotate through the first connecting pipe, so that the material can fall randomly into the mixing tank 11.

[0029] Each of the connecting rods is fixed with a scraper 25. The bottom of the scraper 25 is in close contact with the bottom of the mixing tank 11. When it is necessary to discharge the material after mixing, the scraper 25 can scrape the material at the bottom of the mixing tank 11 to move it, so as to facilitate the complete discharge of the material.

[0030] Both the mixing tank 11 and the auxiliary tank 15 have conical bottoms, which facilitates the discharge of the polystyrene material after batching and mixing during use.

[0031] The above embodiments disclose a polystyrene preparation circulating mixing device. When preparing a polystyrene mixture, the polystyrene raw material is added to the mixing tank 11 through the first feeding pipe 12, and simultaneously, the feed ingredients are added to the auxiliary tank 15 through the second feeding pipe 16. The motor 26 is started, and its output drives a third bevel gear. The third bevel gear meshes with both the first and second bevel gears, causing the first and second bevel gears to drive the transmission pipe 19 and the mounting shaft 17 to rotate, respectively. The mounting shaft 17 rotates in the opposite direction to the transmission pipe 19. The mounting shaft 17 drives the discharge seat 18 to rotate. The discharge seat 18 cooperates with the transmission pipe 19 to transport the material at the bottom of the mixing tank 11 to the top of the transmission pipe 19. At the same time, the transmission pipe 19 mixes the material inside the mixing tank 11 through the second mixing rod. The mounting shaft 17 drives several first mixing rods to mix the ingredients inside the auxiliary box 15. After the ingredients inside the auxiliary box 15 fall through the first discharge hole to the top of the distribution plate 27, the baffle 28 will prolong the falling time of the ingredients. At the same time, the connecting box 22 drives the distribution plate 27 to rotate through the first connecting pipe, so that the ingredients can fall randomly into the mixing tank 11.

[0032] When the mounting shaft 17 and the transmission pipe 19 rotate, the mounting shaft 17 drives the spiral plate 21 to rotate. The spiral plate 21 and the transmission pipe 19 cooperate to transport the material at the bottom of the mixing tank 11 to the connecting box 22. At the same time, the transmission pipe 19 drives the connecting box 22 to rotate. The mounting shaft 17 drives the discharge plate 24 to rotate through the connecting frame 23. The connecting box 22 and the discharge plate 24 rotate in opposite directions. After the material at the bottom of the mixing tank 11 is discharged into the connecting box 22 through one end of the transmission pipe 19, the third mixing rod and the fourth mixing rod can mix the material inside the connecting box 22. Then, when the third discharge hole and the fourth discharge hole coincide, the material inside the connecting box 22 randomly re-enters the mixing tank 11.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
