Description

Technical Field

[0001] This utility model relates to the field of flame retardant production technology, and in particular to a temperature control device for flame retardant production. Background Technology

[0002] The synthesis of flame retardants typically requires a specific temperature range; excessively high or low temperatures can lead to incomplete reactions, increased byproducts, or decreased product quality. Therefore, precise and stable temperature control is crucial for the efficient production of flame retardants.

[0003] Traditional temperature control methods mainly rely on simple cooling water circulation systems or electric heating equipment. These devices have many shortcomings. For example, cooling water circulation systems can usually only achieve relatively coarse temperature regulation, which is difficult to meet the strict temperature accuracy requirements in the flame retardant production process. While electric heating equipment can provide some temperature control, it consumes a lot of energy and is prone to problems such as poor thermal stability and equipment aging in high-temperature environments. In addition, these traditional temperature control devices often lack effective heat insulation and waste heat recovery measures, resulting in a large amount of heat being lost into the environment, which not only wastes energy but may also have an adverse impact on the production environment. Utility Model Content

[0004] This invention is a temperature control device for flame retardant production, proposed to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A temperature control device for flame retardant production includes a vessel body cover and an intelligent controller. Several thermally conductive support members are provided on the inner wall of the vessel body cover. A threaded cooling sleeve is fitted into one side of each thermally conductive support member. A liquid inlet pipe is provided at one end of the threaded cooling sleeve, and a pump body is provided at one end of the liquid inlet pipe. A liquid outlet pipe is provided at the other end of the threaded cooling sleeve. A circulating refrigeration component is provided on one side of the vessel body cover.

[0006] Through the above technical solution, the heat-conducting support on the inner wall of the vessel body shroud conducts the heat inside the vessel body to the threaded cooling jacket. After the pump body is started, the coolant in the cold flow box is pumped to the threaded cooling jacket through the liquid inlet pipe. The coolant absorbs heat as it flows in the threaded cooling jacket. The heated coolant enters the hot flow box through the liquid outlet pipe, and then exchanges heat with the cold flow box through the plate heat exchanger to achieve the cooling circulation of the coolant, thereby controlling the internal temperature of the vessel body.

[0007] This design, through circulating cooling, can precisely control the internal temperature of the reactor, meeting the stringent temperature requirements of flame retardant production and ensuring the stability of flame retardant product quality. The circulating cooling components enable the reuse of coolant, reducing production costs. The use of an intelligent controller automates the temperature control process, improving the accuracy of temperature control and production efficiency.

[0008] Preferably, the circulating refrigeration assembly includes a protective box, which is located on one side of the vessel body cover. The protective box has a cover on its upper side. A hot flow box and a cold flow box are arranged sequentially from top to bottom inside the protective box. A plate heat exchanger is arranged on the lower side of the hot flow box. The pump body is placed inside the cold flow box. One end of the liquid outlet pipe is connected to one side of the hot flow box. The intelligent controller is located on one side of the protective box.

[0009] The above technical solution allows the tank cover to be opened, facilitating maintenance and repair of internal components. The heat flow box receives high-temperature coolant flowing in from the outlet pipe. A plate heat exchanger transfers the heat from the coolant in the heat flow box to the cold flow box, cooling the coolant. The cooled coolant is stored in the cold flow box, and the pump then pumps the coolant from the cold flow box to the threaded cooling jacket, forming a coolant circulation. An intelligent controller controls the operation of the pump and other components, coordinating the entire refrigeration process.

[0010] The circulating refrigeration unit achieves efficient heat exchange through a plate heat exchanger, improving the cooling efficiency of the coolant and ensuring timely temperature control. All components are centrally installed in a protective box, resulting in a compact structure, small footprint, and easy installation and maintenance. The precise control of the intelligent controller makes the circulating refrigeration process more stable and reliable, ensuring that the internal temperature of the vessel remains within a suitable range.

[0011] Preferably, the upper and lower sides of the vessel body cover are provided with soft rubber heat-insulating sealing rings.

[0012] Through the above technical solution, the soft rubber heat insulation sealing rings on the upper and lower sides of the vessel body cover fit tightly against adjacent components during installation to form a sealed structure. During the flame retardant production process, this effectively prevents the heat inside the vessel body cover from being lost to the external environment through the upper and lower gaps, while also preventing external heat from entering the vessel body cover, thus maintaining the stability of the internal temperature of the vessel body.

[0013] The soft rubber heat-insulating sealing ring improves the heat insulation performance of the reactor body cover, reduces heat loss and transfer, lowers the energy consumption of the temperature control device, and improves energy utilization efficiency. At the same time, the good sealing performance prevents external impurities from entering the reactor body, ensuring a clean production environment for flame retardants and contributing to improved product quality.

[0014] Preferably, a fan is provided on the lower side of the vessel body cover and opposite to the heat-conducting support, and a through hole is provided on the outer side of the heat-conducting support.

[0015] With the above technical solution, when the fan on the lower side of the vessel body cover is working, it draws in outside air. The air passes through the through hole of the heat-conducting support and exchanges heat with the heat-conducting support and the threaded cooling jacket, which accelerates the removal of heat from the surface of the threaded cooling jacket, assists the cooling effect of the coolant, and further reduces the internal temperature of the vessel body.

[0016] The combination of the fan and the through hole of the heat-conducting support enhances the heat dissipation capacity of the temperature control device, improves the cooling efficiency, and enables the internal temperature of the reactor to be quickly controlled within a suitable range during the production of flame retardants. The use of air-assisted heat dissipation reduces the dependence on coolant circulation, lowers energy consumption, and improves the operating economy of the equipment.

[0017] Preferably, a duct is provided on one side of the vessel body cover, a waste heat recovery box is provided at one end of the duct, a second fan is provided at the end of the duct near the vessel body cover, and an external control valve and a pressure relief valve are respectively provided on the upper side of the waste heat recovery box.

[0018] Through the above technical solution, the second fan draws the air with residual heat inside the vessel enclosure through the air duct to the waste heat recovery box, where the waste heat can be recovered and utilized. The external control valve can control the connection between the waste heat recovery box and external equipment and the heat transfer. The pressure relief valve automatically opens when the pressure in the waste heat recovery box is too high to release the pressure and ensure the safe operation of the equipment.

[0019] The installation of air ducts, fan 2, and waste heat recovery box enables the recovery and utilization of waste heat during the flame retardant production process, improving the overall energy utilization rate and reducing production energy consumption. At the same time, the exhaust of hot air from the vessel enclosure helps maintain a stable internal temperature and reduces the impact of heat accumulation on the production process. The installation of pressure relief valve ensures the safety of equipment operation and avoids safety accidents caused by excessive pressure.

[0020] In summary, this utility model enables the heat-conducting support to quickly transfer heat from the vessel body shroud to the threaded cooling jacket. The special structural design of the threaded cooling jacket increases the contact area between the coolant and the heat-conducting support, improving heat exchange efficiency. This synergistic effect allows the heat inside the vessel body shroud to be quickly removed, further enhancing the temperature control performance of the temperature control device and providing a strong guarantee for the stable production of flame retardants.

[0021] In this invention, a soft rubber heat-insulating sealing ring is installed on the upper and lower sides of the vessel body cover, effectively blocking heat transfer and reducing heat exchange between the vessel body cover and the external environment. This design not only reduces coolant energy consumption and energy waste, but also improves the energy efficiency of the temperature control system.

[0022] In this invention, the second fan introduces the waste heat generated by the vessel body enclosure into the waste heat recovery box through the air duct. The heat in the waste heat recovery box can be connected to other devices or systems that require heat energy through an external control valve, so as to realize the recovery and reuse of waste heat. This waste heat recovery and utilization method makes full use of the waste heat resources generated in the production process, reduces the demand for fresh energy, further improves the energy utilization rate, reduces the energy consumption cost of enterprises, and also meets the environmental protection requirements of energy conservation and emission reduction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] like Figures 1-2 As shown, a temperature control device for flame retardant production includes a vessel body shroud 1 fixedly installed on the outside of the flame retardant production vessel body, ensuring a tight fit. Several thermally conductive support members 2 are evenly installed on the inner wall of the vessel body shroud 1. These support members 2 can be made of highly thermally conductive metal materials such as aluminum alloy or copper alloy to ensure good heat conduction performance. One side of each thermally conductive support member 2 is designed with a fitting groove for fitting a threaded cooling sleeve 3.

[0027] The threaded cooling sleeve 3 is fitted into the fitting groove of the heat-conducting support 2 to ensure close contact with the heat-conducting support 2 for efficient heat conduction. One end of the threaded cooling sleeve 3 is connected to the liquid inlet pipe 4, and the other end of the liquid inlet pipe 4 is connected to the pump body 5. The pump body 5 is installed in the cold flow box 11 of the circulating refrigeration component to drive the circulation of coolant. The other end of the threaded cooling sleeve 3 is connected to the liquid outlet pipe 6, and the other end of the liquid outlet pipe 6 is connected to the heat flow box 9.

[0028] The circulating refrigeration assembly includes a protective box 7, which is installed on one side of the vessel body cover 1. A box cover 8 is installed on its upper side. Inside the protective box 7, a heat flow box 9 and a cold flow box 11 are installed from top to bottom. A plate heat exchanger 10 is installed on the lower side of the heat flow box 9. One end of the liquid outlet pipe 6 is connected to one side of the heat flow box 9 to form a circulation path for the coolant. An intelligent controller 19 is installed on one side of the protective box 7 to control the operation of the entire temperature control device.

[0029] On the upper and lower sides of the vessel body cover 1, soft rubber heat insulation sealing rings 12 are installed respectively. These sealing rings can be made of high temperature resistant silicone material to ensure good heat insulation and sealing performance. On the lower side of the vessel body cover 1, a fan 13 is installed opposite to the heat-conducting support 2. The outer side of the heat-conducting support 2 is designed with through holes so that the airflow generated by the fan 13 can dissipate heat through these through holes.

[0030] On one side of the vessel body cover 1, an air duct 14 is installed. One end of the air duct 14 is connected to the waste heat recovery box 16. A fan 15 is installed at the end of the air duct 14 near the vessel body cover 1 to introduce the waste heat generated by the vessel body cover 1 into the waste heat recovery box 16 through the air duct 14. An external control valve 17 and a pressure relief valve 18 are installed on the upper side of the waste heat recovery box 16. The external control valve 17 is used to connect external equipment that requires heat energy. The pressure relief valve 18 is used to automatically relieve pressure when the system pressure is too high to ensure safety.

[0031] After completing the above assembly and connection, start the temperature control device. First, set the target temperature through the intelligent controller 19. The intelligent controller 19 automatically controls the speed of the pump body 5 according to the preset temperature parameters to adjust the flow rate of the coolant, thereby achieving the initial adjustment of the temperature inside the vessel body cover 1.

[0032] After the pump body 5 starts, it delivers the coolant in the cold flow box 11 to the threaded cooling jacket 3 through the inlet pipe 4. The coolant flows inside the threaded cooling jacket 3, contacts the thermally conductive support 2, and absorbs its heat. Subsequently, the heated coolant flows into the hot flow box 9 through the outlet pipe 6. In the hot flow box 9, the coolant transfers heat to the plate heat exchanger 10. The plate heat exchanger 10 utilizes its efficient heat exchange performance to transfer heat from the coolant to the cold flow medium, such as cooling water, on the other side, thereby lowering the coolant temperature. The cooled coolant returns to the cold flow box 11, completing one cycle.

[0033] The soft rubber heat-insulating sealing ring 12 effectively blocks the heat exchange between the vessel body cover 1 and the external environment, reducing heat loss. The fan 15 introduces the waste heat generated by the vessel body cover 1 into the waste heat recovery box 16 through the air duct 14. The heat in the waste heat recovery box 16 can be connected to other devices or systems that require heat energy through the external control valve 17 to realize the recovery and reuse of waste heat. At the same time, the pressure relief valve 18 automatically opens when the system pressure is too high to ensure the safe operation of the system.

[0034] During operation, fan 13 generates airflow, which passes through the through hole on the outside of the heat-conducting support 2 to force-cool the heat-conducting support 2, further reducing the temperature of the heat-conducting support 2, assisting the cooling effect of the threaded cooling jacket 3, and improving the heat dissipation efficiency of the entire temperature control device.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
