Description

Technical Field

[0001] This utility model relates to the field of mold release agent technology, and more specifically, to a production reaction device for mold release agents. Background Technology

[0002] Currently, mold release agents are widely used in industries such as metal casting, rubber products, and plastic injection molding. Their production process typically involves heating, stirring, and chemically reacting various organic or inorganic raw materials under specific conditions. This process inevitably generates large amounts of waste gas containing volatile organic compounds (VOCs), aerosols, and some corrosive components. To meet increasingly stringent environmental emission standards, existing processes generally employ multi-stage waste gas treatment devices for purification, such as condensers, adsorption devices, or scrubbing equipment. However, these devices are mostly independently arranged, with dispersed process flows, making coordinated operation difficult and resulting in low system integration and poor operating efficiency.

[0003] Furthermore, the production process of mold release agents involves multiple stages, including raw material pretreatment, reaction generation, waste gas collection, finished product separation, liquid transportation, and storage. Due to insufficient compatibility of existing equipment in terms of function, structure, and interfaces, numerous transfer containers and manual intervention steps are often required, increasing operational complexity, energy consumption, and land use. Simultaneously, traditional systems rely heavily on single methods such as condensation or activated carbon adsorption for waste gas treatment, making it difficult to achieve efficient synergistic purification of multiple harmful gases, thus limiting the improvement of overall emission control levels. Therefore, there is an urgent need for a more compact, functionally integrated, and highly efficient reaction system capable of achieving high-quality mold release agent production while simultaneously completing multi-stage waste gas purification and resource recovery, addressing the prominent issues of equipment incompatibility, discontinuous processes, and insufficient environmental performance in traditional technologies. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a production reaction device for release agents to solve the above problems.

[0005] The present invention adopts the following solution:

[0006] This application provides a production reaction apparatus for a release agent, including a reaction tank, a receiving tank, a buffer tank, a scrubbing tower, and a finished product storage tank. The reaction tank is used to heat, stir, and react the raw materials input into the tank. The reaction tank outputs the release agent produced in the tank to the finished product storage tank through a material pump. The receiving tank is used to receive the waste gas output from the reaction tank, and the receiving tank is further connected to the buffer tank, which is connected to the scrubbing tower. A first condenser is provided between the reaction tank and the receiving tank, and a second condenser is provided between the receiving tank and the buffer tank. The scrubbing tower is connected at its outlet to a fan equipped with an activated carbon box for rapid output of the treated waste gas.

[0007] As a further improvement, a heater is connected to the outside of the reaction vessel, which is used to further heat the inside of the vessel.

[0008] As a further improvement, the heater is connected to a third condenser, and the first condenser, the second condenser, and the third condenser are all connected to the same cooling tower.

[0009] As a further improvement, the cooling tower is connected to an external water tank, which is connected to a third condenser via a water pump.

[0010] As a further improvement, the buffer tank is used to temporarily store the exhaust gas transmitted from the receiving tank, and a vacuum pump is also provided between the buffer tank and the scrubbing tower.

[0011] As a further improvement, an air compressor is connected to the outside of the reaction vessel, which is used to provide compressed air to the inside of the vessel to assist in stirring or propelling the raw materials.

[0012] As a further improvement, the reaction vessel includes a vessel body with an inner cylinder, a rotating motor mounted on the vessel body, and a stirrer connected to the rotating motor and placed inside the vessel body.

[0013] As a further improvement, the tank body is provided with a distillation column and a feed inlet at the top, as well as a nitrogen inlet on the side. The distillation column is connected to the inner cylinder, and the nitrogen inlet is also connected to the inner cylinder. The tank body is provided with a mounting hole in the middle, and the rotating motor is mounted on the mounting hole and is linearly connected to the agitator through a reducer.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] 1. The production reaction device for release agent of this application undertakes the functions of heating, stirring and reacting raw materials through the reaction tank. After the reaction is completed, the finished product is directly transported to the finished product storage tank through the material pump, which simplifies the material transfer process, reduces intermediate links, and improves the automation level and production efficiency of the system. The first condenser and the second condenser are respectively used for gas treatment between the reaction tank and the receiving tank and between the receiving tank and the buffer tank, which effectively realizes the condensation and recovery of condensable gases, reduces the emission of volatile organic compounds, and improves the resource utilization rate.

[0016] 2. Among them, the configuration of the buffer tank can effectively regulate the pressure and flow rate fluctuations of the gas in the system, ensuring that the scrubbing tower operates under the best working conditions, improving the stability and efficiency of the overall waste gas treatment. The scrubbing tower, combined with its own liquid phase spray system, can effectively remove dissolved pollutants in the gas, and further remove them through activated carbon adsorption and fan discharge at the outlet, achieving synergistic removal of multiple pollutants and odor control, ensuring that the waste gas meets emission standards. Thus, the various modules are arranged in series according to the production process, with a small footprint and short connection path, which is conducive to installation, commissioning and subsequent maintenance, and is suitable for rapid deployment in existing plants.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. Example

[0022] Combination Figures 1 to 2 This embodiment provides a production reaction apparatus for a release agent, including a reaction tank 1, a receiving tank 2, a buffer tank 3, a scrubbing tower 4, and a finished product storage tank 5. The reaction tank 1 is used to heat, stir, and react the raw materials input into the tank. The release agent produced in the reaction tank 1 is output to the finished product storage tank 5 via a material pump 6. The receiving tank 2 is used to receive the waste gas output from the reaction tank 1, and is further connected to the buffer tank 3, which is connected to the scrubbing tower 4. A first condenser 7 is provided between the reaction tank 1 and the receiving tank 2, and a second condenser 8 is provided between the receiving tank and the buffer tank 3. The scrubbing tower 4 is connected at its outlet to a fan 10 equipped with an activated carbon box 9 for rapid output of the treated waste gas.

[0023] The aforementioned production reaction device for the release agent uses reaction tank 1 to heat, stir, and react the raw materials. After the reaction is completed, the finished product is directly transported to the finished product storage tank 5 by material pump 6, which simplifies the material transfer process, reduces intermediate links, and improves the automation level and production efficiency of the system. The first condenser 7 and the second condenser 8 are respectively used for gas treatment between reaction tank 1 and receiving tank 2 and between receiving tank 2 and buffer tank 3, which effectively realizes the condensation and recovery of condensable gases, reduces the emission of volatile organic compounds, and improves resource utilization.

[0024] In particular, the configuration of buffer tank 3 can effectively regulate the pressure and flow rate fluctuations of the gas in the system, ensuring that scrubbing tower 4 operates under optimal working conditions, improving the stability and efficiency of overall waste gas treatment. Scrubbing tower 4, combined with its built-in liquid-phase spray system, can effectively remove dissolved pollutants from the gas, and further remove them at the outlet through activated carbon adsorption and fan 10, achieving synergistic removal of multiple pollutants and odor control, ensuring that waste gas meets emission standards. Thus, the various modules are arranged in series according to the production process, occupying a small area and having short connection paths, which is conducive to installation, commissioning, and subsequent maintenance, and is suitable for rapid deployment in existing plant buildings.

[0025] In this embodiment, a heater 11 is externally connected to the reaction vessel 1, which is used to further heat the contents of the vessel. This external heater 11 provides an additional heat source, significantly increasing the heating rate of the materials inside the reaction vessel 1, accelerating the chemical reaction process, thereby shortening the overall production cycle and increasing the output per unit time. Compared to relying solely on built-in heating elements, the external heater 11 typically has a more precise temperature control system, enabling precise adjustment of temperature changes, which helps maintain stable reaction process parameters and ensures consistent quality of the release agent.

[0026] In this embodiment, the heater 11 is connected to a third condenser 12, and the first condenser 7, the second condenser 8, and the third condenser 12 are all connected to the same cooling tower 23. Clearly, by installing the third condenser 12 at the outlet of the heater 11, volatile organic components or other condensable gases released during the heating process can be effectively recovered, further improving material utilization and reducing resource waste. Furthermore, by uniformly connecting the first condenser 7, the second condenser 8, and the third condenser 12 to the same cooling tower 23, centralized management and allocation of cooling resources are achieved, avoiding the duplication of multiple independent cooling systems, reducing system redundancy, and saving energy and operating costs.

[0027] It should be mentioned that the cooling tower 23 is connected to an external water tank 24, which is connected to the third condenser 12 via a water pump 13. The external water tank and the water pump 13 form an auxiliary circulation system, which can continuously provide cooling water to the third condenser 12, effectively ensuring the efficient condensation of gases escaping during the heating process and improving the overall cooling efficiency of the system.

[0028] In this embodiment, the buffer tank 3 is used to temporarily store the waste gas transmitted from the receiving tank 2, and a vacuum pump 14 is also provided between the buffer tank 3 and the scrubbing tower 4. The buffer tank 3 temporarily stores the waste gas, effectively reducing the instantaneous fluctuations in waste gas emissions during the reaction process, maintaining a stable airflow into the scrubbing tower 4, thereby improving the gas-liquid contact efficiency and purification capacity of the scrubbing tower 4. Furthermore, the vacuum pump 14, located between the buffer tank 3 and the scrubbing tower 4, can create a negative pressure environment, actively extracting the waste gas flow, enhancing the system's waste gas delivery rate, preventing backflow or stagnation of waste gas, and contributing to the continuous and stable operation of the overall process.

[0029] In this embodiment, an air compressor 15 is externally connected to the reaction tank 1. The air compressor 15 provides compressed air to the tank to assist in stirring or propelling the raw materials. It is understood that the compressed air output by the air compressor 15 can create gas turbulence, effectively breaking the laminar flow state of the liquid phase or slurry, improving the mixing efficiency within the reaction tank 1, and promoting sufficient contact and uniform reaction of the various reaction components. For raw materials with high viscosity or a significant tendency to settle, the compressed air can provide additional propulsion, assisting the raw materials in flowing within the tank or being transported to other device ports, reducing reliance on mechanical pumps and extending pump lifespan.

[0030] like Figure 2 As shown, in this embodiment, the reaction vessel 1 includes a vessel body 16 with an inner cylinder, a rotary motor 17 mounted on the vessel body 16, and a stirrer 18 connected to the rotary motor 17 and placed inside the vessel body 16. The inner cylinder optimizes the heat distribution path within the vessel body 16, forming a stable flow field circulation, improving heating or cooling efficiency, and enhancing the convective stirring effect of the reaction medium to ensure balanced reaction conditions. Furthermore, the rotary motor 17 drives the stirrer 18 to rotate continuously via a mechanical connection, providing a stable and controllable power source. The rotation speed can be adjusted according to different raw materials or process stages to achieve customized mixing requirements.

[0031] Specifically, the tank 16 is equipped with a distillation column 19 and a feed inlet 20 at the top, and a nitrogen inlet 21 on the side. The distillation column 19 is connected to the inner cylinder, and the nitrogen inlet 21 is also connected to the inner cylinder. The tank 16 has a mounting hole in the middle, and the rotating motor 17 is mounted on the mounting hole and linearly connected to the stirrer 18 through a reducer 22. Thus, the distillation column 19 is connected to the inner cylinder, enabling real-time separation and condensation recovery of volatile byproducts (such as water, alcohol, and light solvents) during the reaction, which helps in controlling the reaction equilibrium and improving product purity.

[0032] The nitrogen inlet 21 is located on the side and communicates with the inner cylinder, allowing for a continuous supply of inert gas to the reaction space. This provides effective atmosphere protection in reaction scenarios requiring oxygen protection, moisture protection, or positive pressure. Furthermore, the top feed inlet 20 facilitates the gradual addition of liquid or solid raw materials. Combined with an automatic feeding system, it enables precise control of reactant concentration and feeding rhythm, improving process control accuracy. Additionally, the rotary motor 17 is installed at the mounting hole in the middle of the tank 16 and linearly connected to the agitator 18 via a reducer 22. This reduces the length of the transmission chain and energy consumption, resulting in high transmission efficiency, good structural stability, and facilitating long-term continuous operation.

[0033] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
