Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a novel EPS particle preparation reaction vessel. Background Technology

[0002] A reaction vessel is a container that provides a reaction site for various substances to undergo chemical reactions. It includes a vessel body, a stirrer, and a transmission device. The stirrer is connected to the transmission device via a coupling and extends into the vessel body. The reactants enter the reaction vessel body through the feed inlet. During use, the stirrer rotates under the drive of the transmission device, thereby agitating the reactants in the vessel body to ensure a complete reaction. EPS granules are polystyrene products with added foaming agents. They appear as colorless, transparent, bead-like granules and possess properties such as lightweight, thermal insulation, and shock absorption. A reaction vessel is required in the preparation of EPS granules to mix and react the raw materials. Existing patent publication number CN222724322U discloses a novel EPS particle preparation reactor. By installing a pressure sensor inside the reactor cavity and a pressure relief valve at the top of the reactor, the pressure inside the reactor cavity is monitored, thereby controlling the opening or closing of the pressure relief valve to prevent the risk of reactor explosion. The stirring blades are L-shaped, which not only stir the materials but also scrape off materials adhering to the inner wall of the reactor cavity, making the material reaction more complete. A self-priming impeller and a gas inlet are also connected to the stirring shaft, further enhancing the stirring of the materials. The aforementioned patent features an integrated vessel body. The material on the inner wall of the vessel is scraped off by rotating the stirring blades to achieve a certain cleaning effect. However, this makes subsequent cleaning difficult, and some materials adhere to the inner wall of the vessel and become dry and stubborn, resulting in poor scraping and cleaning. In addition, the stirring blades are in rigid contact with the inner wall of the vessel, and with prolonged use, the stirring blades may damage the inner wall of the reaction vessel. Utility Model Content

[0003] The purpose of this invention is to provide a novel EPS particle preparation reactor to solve the problems mentioned in the background art, which has an integral structure and achieves a certain cleaning effect by scraping the material on the inner wall of the reactor through the rotation of the stirring blades. However, this is not convenient for subsequent cleaning work, and some materials adhere to the inner wall of the reactor and become dry and stubborn, making scraping and cleaning ineffective. At the same time, the stirring blades are in rigid contact with the inner wall of the reactor, and the stirring blades may cause damage to the inner wall of the reactor with long-term use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel EPS particle preparation reactor, comprising a reactor body and a lid fixedly installed on the top of the reactor body. A cleaning assembly is movably installed inside the reactor body, and a staggered stirring and scraping assembly is fixedly installed outside the cleaning assembly. The cleaning assembly includes a hollow rod rotatably installed inside the reactor body and the lid. A transmission rod is rotatably installed on the top of the lid, located outside the hollow rod. A limiting cover is fixedly installed on the top of the lid, located outside the hollow rod and the transmission rod. Meshing gears are fixedly installed on the outside of both the hollow rod and the transmission rod. A reduction mechanism is fixedly installed on the top of the limiting cover. A motor is fixedly installed on the top of the reduction mechanism. A rotary joint is movably installed on the top of the hollow rod. A water outlet is opened on the side of the hollow rod. A water outlet pipe connected to the water outlet is fixedly installed on the outside of the stirring and scraping assembly. A one-way nozzle is fixedly installed on the side of the water outlet pipe.

[0005] Preferably, the motor is driven by a reduction gear and a transmission rod.

[0006] Preferably, the water outlet pipe is arranged in an "L" shape, and the one-way nozzles are fixedly installed at equal intervals on the vertical section of the water outlet pipe.

[0007] Preferably, the unidirectional nozzle is tilted at a 45-degree angle.

[0008] Preferably, the stirring and scraping assembly includes an L-shaped rod fixedly installed outside the hollow rod. The side of the L-shaped rod has equidistant sliding holes. A sliding column is movably engaged inside the sliding holes. A limiting plate is movably installed inside the sliding column. A vertical plate is fixedly installed outside the sliding column. A support spring located between the L-shaped rod and the vertical plate is movably sleeved outside the sliding column. A slot is opened inside the vertical plate. A retaining strip is movably engaged inside the slot. A scraper that fits against the inner wall of the reactor is fixedly connected to the outer side of the retaining strip.

[0009] Preferably, the limiting plate is threadedly connected to the sliding column, and the scraper is made of rubber.

[0010] Preferably, the top of the vessel lid is provided with a feed inlet, the bottom of the reactor body is provided with a discharge outlet, and a pressure valve is fixedly installed on the top of the vessel lid.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. High-pressure water is pumped into the hollow rod through a water pipe connected to the rotary joint and sent into the outlet pipe through the outlet to the one-way nozzle. The water is sprayed onto the inner wall of the reactor body through the one-way nozzle. The high-pressure water jet washes and softens the stubborn residues on the inner wall of the reactor body. Combined with the stirring and scraping components, the inner wall of the reactor body is scraped, which thoroughly cleans the inner wall of the reactor body, improving the convenience and cleaning effect of cleaning. 2. The support spring is located between the L-shaped rod and the vertical plate, providing elastic support for the scraper and pushing the sliding column to slide outward in the sliding hole. The limiting plate limits the sliding column, so that the scraper fits against the inner wall of the reactor body. As the L-shaped rod rotates, the scraper scrapes off the material on the inner wall of the reactor body, ensuring that the material is mixed evenly. At the same time, it avoids the scraper from rigidly contacting the reactor body and damaging the inner wall of the reactor body, thus avoiding damage to the inner wall of the reactor body.

[0014] 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.

[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a novel EPS particle preparation reactor, comprising a reactor body 1 and a reactor cover 2 fixedly installed on the top of the reactor body 1. A cleaning assembly 3 is movably installed inside the reactor body 1, and a staggered stirring and scraping assembly 4 is fixedly installed outside the cleaning assembly 3. The cleaning assembly 3 includes a hollow rod 31 rotatably installed inside the reactor body 1 and the reactor cover 2. A transmission rod 32 is rotatably installed on the top of the reactor cover 2, located outside the hollow rod 31. A limiting cover 33 is fixedly installed on the top of the reactor cover 2, located outside the hollow rod 31 and the transmission rod 32. Meshing gears 34 are fixedly installed on the outside of both the hollow rod 31 and the transmission rod 32. A reduction mechanism 35 is fixedly installed on the top of the limiting cover 33. A motor 36 is fixedly installed, a rotary joint 37 is movably installed on the top of the hollow rod 31, and a water outlet 38 is opened on the side of the hollow rod 31. A water outlet pipe 39 connected to the water outlet 38 is fixedly installed on the outside of the stirring and scraping assembly 4. A one-way nozzle 310 is fixedly installed on the side of the water outlet pipe 39. High-pressure water is pumped into the hollow rod 31 through the water pipe connected to the rotary joint 37 and sent into the water outlet pipe 39 through the water outlet 38 to reach the one-way nozzle 310. The water is sprayed onto the inner wall of the reactor body 1 through the one-way nozzle 310. The high-pressure water jet washes and softens the stubborn residues on the inner wall of the reactor body 1. Combined with the scraping and scraping assembly 4, the inner wall of the reactor body 1 is scraped, and the inner wall of the reactor body 1 is thoroughly cleaned, improving the convenience and cleaning effect of cleaning.

[0016] The motor 36 drives the transmission rod 32 through the reduction mechanism 35, thereby driving the transmission rod 32 to rotate. The rotation of the transmission rod 32 is transmitted to the hollow rod 31 through the meshing gear 34, so that the hollow rod 31 rotates synchronously, ensuring the stability of power transmission. The speed is adjusted by the reduction mechanism 35 to meet the needs of stirring and cleaning inside the reactor body 1.

[0017] The water outlet pipe 39 is arranged in an "L" shape, and the one-way nozzles 310 are fixedly installed at equal intervals on the vertical section of the water outlet pipe 39. The one-way nozzles 310 arranged at equal intervals can cover a larger area of ​​the inner wall of the reactor body 1, improving cleaning efficiency. The "L" shape of the water outlet pipe 39 not only facilitates installation but also ensures that the flow rate and pressure of the high-pressure water remain stable. The vertical section allows the one-way nozzles 310 to get closer to the inner wall of the reactor body 1, further enhancing the rinsing effect and avoiding cleaning blind spots caused by water flow dispersion.

[0018] The one-way nozzle 310 is set at a 45-degree angle. The 45-degree angle design can effectively increase the impact force of the water flow and ensure that the high-pressure water is sprayed onto the inner wall of the reactor body 1 at the best angle, thereby enhancing the cleaning ability during the cleaning process.

[0019] Please see Figure 2 and Figure 5 The stirring and scraping assembly 4 includes an L-shaped rod 41 fixedly installed outside the hollow rod 31. Sliding holes 42 are equidistantly opened on the side of the L-shaped rod 41. A sliding column 43 is movably engaged inside the sliding holes 42. A limit plate 44 is movably installed on the inner side of the sliding column 43. A vertical plate 45 is fixedly installed on the outer side of the sliding column 43. A support spring 46 is movably sleeved on the outer side of the sliding column 43, located between the L-shaped rod 41 and the vertical plate 45. A slot 47 is opened inside the vertical plate 45. A locking strip 48 is movably engaged inside the slot 47. A sticker is fixedly connected to the outer side of the locking strip 48. The scraper 49 is attached to the inner wall of the reactor body 1. The support spring 46 is located between the L-shaped rod 41 and the vertical plate 45, providing elastic support for the scraper 49. It pushes the sliding column 43 to slide outward in the sliding hole 42. The limiting plate 44 limits the sliding column 43, so that the scraper 49 is attached to the inner wall of the reactor body 1. As the L-shaped rod 41 rotates, the scraper 49 scrapes off the material on the inner wall of the reactor body 1, ensuring that the material is mixed evenly. At the same time, it avoids the scraper 49 from rigidly contacting the reactor body 1 and damaging the inner wall of the reactor body 1, thus avoiding damage to the inner wall of the reactor body 1.

[0020] The limiting plate 44 is threadedly connected to the sliding column 43. The scraper 49 is made of rubber. The limiting plate 44 is tightly fixed to the sliding column 43 by the threaded connection, which can play a limiting role and facilitate disassembly for maintenance. The rubber scraper 49 has good high temperature resistance and wear resistance, and can provide appropriate friction when in contact with the inner wall of the reactor body 1, while avoiding scratches or other forms of damage to the inner wall. The elasticity of the scraper 49 allows it to adapt to the slight unevenness of the inner wall of the reactor body 1, further improving the cleaning effect and the uniformity of material mixing.

[0021] Please see Figure 1 and Figure 2 The top of the lid 2 is provided with a feed inlet 5, and the bottom of the reactor body 1 is provided with a discharge outlet 6. A pressure valve 7 is fixedly installed on the top of the lid 2. The pressure valve 7 can effectively regulate the pressure inside the reactor body 1 to ensure a stable reaction environment during the preparation of EPS particles. The feed inlet 5 facilitates the feeding of raw materials, and the discharge outlet 6 is located at the bottom of the reactor body 1 to facilitate the discharge of finished products.

[0022] Working principle: Raw materials are fed into the reactor body 1 through the feed inlet 5. The reactor body 1 heats the materials, and the transmission rod 32 is driven to rotate by the control motor 36 and the reduction mechanism 35. The transmission rod 32 and the hollow rod 31 are driven by the gear 34 to rotate the hollow rod 31. The rotation of the hollow rod 31 drives the external stirring and scraping component 4 to rotate inside the reactor body 1 to stir and mix the materials. The scraper 49 is supported by the support spring 46 located between the L-shaped rod 41 and the vertical plate 45, which pushes the sliding column 43 to slide outward in the sliding hole 42. The limiting plate 44 limits the sliding column 43, so that the scraper 49 is attached to the inner wall of the reactor body 1. As the L-shaped rod 41 rotates, it scrapes the materials on the inner wall of the reactor body 1, ensuring that the materials are fully mixed and avoiding rigid contact between the scraper 49 and the reactor body 1, which may cause damage to the inner wall of the reactor body 1. During cleaning, high-pressure water is pumped into the hollow rod 31 through a water pipe connected to the rotary joint 37 and sent into the outlet pipe 39 through the outlet 38 to the one-way nozzle 310. The water is then sprayed onto the inner wall of the reactor body 1 through the one-way nozzle 310. The high-pressure water jet washes and softens the stubborn residues on the inner wall of the reactor body 1. Combined with the scraper 49 scraping the inner wall of the reactor body 1, the inner wall of the reactor body 1 is thoroughly cleaned. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[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.
