Description

[Technical Field]

[0001] This utility model relates to the technical field of logistics conveying devices, and in particular to a polyurethane production equipment. [Background Technology]

[0002] Polyurethane, short for polyurethane, is a material with excellent oil resistance, toughness, abrasion resistance, aging resistance, and adhesive properties. Therefore, it is widely used in the manufacture of materials such as foams, plastics, fibers, coatings, adhesives, running tracks, and flooring. In the production process of polyurethane, a stirring and heating device is used. Stirring the polyurethane raw materials with this device can evenly mix the raw materials, improve the reaction speed, and improve product quality. Existing stirring and heating devices mainly use a stirring rod to stir the raw materials in the tank and use heating wires to heat the inner wall of the tank, so that the heat is transferred to the raw materials, thereby achieving the production of polyurethane.

[0003] While the above method can achieve stirring and heating of raw materials, the following problems still exist: Since the above method mainly heats the raw materials through heating wires, it is difficult to control the temperature of the heating wires. If the reaction temperature is too high, the -NH- on the urethane bonds in the polyurethane raw materials may continue to react with the NCO functional groups to form urethane, thereby changing the structure of the polyurethane prepolymer and affecting the overall performance of the polyurethane. [Utility Model Content]

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a polyurethane production equipment that can control the internal heating temperature of the tank.

[0005] To achieve the above objectives, this utility model proposes a polyurethane production equipment, comprising: a tank, a feed pipe fixedly connected to the top surface of the tank, and a discharge pipe fixedly connected to the bottom surface of the tank. A solenoid valve is fixedly connected to both the feed pipe and the discharge pipe. The tank is equipped with a stirring component and also includes: a heat-conducting block, a temperature-conducting pipe, a heating wire, a housing, a temperature sensor, and a control component.

[0006] The heat-conducting block is fixedly connected to the inner wall of the tank;

[0007] The temperature-conducting tube is fixedly connected to the inner wall of the heat-conducting tube, and the heating wire is fixedly connected to the inner wall of the heat-conducting block.

[0008] The box body is fixedly connected to the side wall of the tank body. A liquid pump is fixedly connected inside the box body. The temperature guide pipe is connected to the liquid pump. The end of the temperature guide pipe away from the liquid pump is connected to the box body.

[0009] The temperature sensor is fixedly connected to the box body, and the control component is fixedly connected to the tank body. The temperature sensor and the control component are electrically connected, and the control component is electrically connected to the liquid pump and the heating wire.

[0010] Preferably, the control component includes a control panel fixedly connected to the tank body, and the control panel is electrically connected to a liquid pump disposed inside the tank body.

[0011] Preferably, a cooler is fixedly connected to the housing, and a second liquid pump is fixedly connected inside the housing. The second liquid pump is connected to the cooler through a pipe, and the cooler is connected to the housing through a pipe. The control panel can be electrically connected to the second liquid pump and the cooler.

[0012] Preferably, an air nozzle is fixedly connected inside the housing, and an air pump is fixedly connected to the housing. The air pump and the air nozzle are connected via a transmission pipe, and a one-way valve is fixedly connected to the transmission pipe. The air pump is electrically connected to the control panel.

[0013] Preferably, the stirring component includes a stirring rod rotatably connected to the tank body, and a motor is fixedly connected to the bottom surface of the tank body, with the output shaft of the motor fixedly connected to the stirring rod.

[0014] Preferably, a scraper is fixedly connected to the stirring rod, and one end of the scraper can be in contact with the inner wall of the tank.

[0015] Preferably, a scraper is fixedly connected to the stirring rod, and the scraper can adhere to the inner wall of the bottom of the tank.

[0016] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model uses a heating wire set inside the temperature-conducting block to conduct temperature to the block. The temperature-conducting block then conducts heat to the water in the temperature-conducting pipe, heating the water and transferring the temperature to the raw material through the pipe. Once the raw material temperature rises to a certain value, the temperature sensor detects the water temperature as it enters the tank and transmits this information to the control unit. The control unit then shuts off the heating wire and the pump, maintaining the water temperature within the required range. When the water temperature drops to a certain level, the temperature sensor detects the water temperature again and transmits this information to the control unit. The control unit then activates the pump and the heating wire, heating the interior of the tank and thus controlling the temperature of the raw material. By controlling the water temperature within the required range, the temperature control effect of the raw material is improved, reducing the impact on the overall performance of the polyurethane caused by excessively high temperatures.

[0027] like Figures 1 to 4 A polyurethane production equipment includes: a tank 1, a feed pipe 2 fixedly connected to the top surface of the tank 1, and a discharge pipe 3 fixedly connected to the bottom surface of the tank 1. Solenoid valves 4 are fixedly connected to both the feed pipe 2 and the discharge pipe 3. An agitator is installed inside the tank 1, wherein the agitator is mainly used to agitate the raw materials, the discharge pipe 3 is used to discharge the raw materials, and the feed pipe 2 is mainly used to put the raw materials into the tank 1.

[0028] The production equipment in this utility model also includes:

[0029] The system includes a temperature-conducting pipe 6, a heat-conducting block 5, and a heating wire 7. The temperature-conducting pipe 6 is fixedly connected inside the tank body 1, while the heat-conducting block 5 is fixedly connected inside the temperature-conducting pipe 6, and the heating wire 7 is fixedly connected inside the heat-conducting block. The heating wire 7 heats the heat-conducting block 5, which in turn transfers heat to the water inside the temperature-conducting pipe 6, thereby heating the raw materials.

[0030] The tank 9 and the pump 8 are fixedly connected to the tank 1 and are mainly used to store water. The pump 8 is fixedly connected inside the tank 9 and is connected to the temperature-conducting pipe 6. The pump 8 is mainly used to draw water from the tank 9 into the temperature-conducting pipe 6 and to transfer water from the temperature-conducting pipe 6 into the tank 9, thereby realizing water circulation.

[0031] Temperature sensor 10 and control component 11 are fixedly connected inside the housing 9 and are mainly used to sense the temperature inside the housing 9. Control component 11 is fixedly connected to the tank 1 and is electrically connected to temperature sensor 10, liquid pump 8 and heating wire 7. It is mainly used to control the start of liquid pump 8 and heating wire 7.

[0032] Specifically, since the control component 11 includes a control panel 12 fixedly connected to the tank body 1, the control panel 12 is electrically connected to the liquid pump 8 installed in the box body 9. The control panel 12 is mainly used to control the liquid pump 8 and the heating wire 7.

[0033] Specifically, a cooler 13 is fixedly connected to the housing 9, and a second liquid pump 14 is fixedly connected inside the housing 9. The second liquid pump 14 is connected to the cooler 13 through a pipe, and the cooler 13 is connected to the housing 9 through a pipe. The control panel 12 can be electrically connected to the second liquid pump 14 and the cooler 13. Therefore, the liquid pump 14 draws liquid from the housing 9 and enters the cooler 13 through the pipe, thereby achieving the cooling of water by the cooler 13. Once the water is cooled, it returns to the housing 9 through the pipe, thus realizing the circulation of water.

[0034] Specifically, an air nozzle 15 is fixedly connected inside the housing 9, and an air pump 16 is fixedly connected to the housing 9. The air pump 16 and the air nozzle 15 are connected through a transmission pipe 17. A one-way valve 18 is fixedly connected to the transmission pipe 17. The air pump 16 is electrically connected to the control panel 12. Therefore, the control panel 12 controls the air pump 16 to start. The air pump 16 transmits airflow through the transmission pipe 17 into the air nozzle 15, thereby realizing the airflow being discharged into the water through the air nozzle 15, thereby achieving the agitation of the water by the airflow, and thus increasing the uniform agitation of the water in the housing 9 as the water cooled in the cooler 13 is transmitted to the housing 9.

[0035] Specifically, since the stirring component includes a stirring rod 19 rotatably connected inside the tank 1, and a motor 20 is fixedly connected to the bottom surface of the tank 1, and the output shaft of the motor 20 is fixedly connected to the stirring rod 19, the stirring rod 19 is driven to rotate by the motor 20, and the stirring rod 19 stirs the tank 1, thereby realizing the stirring of the raw materials inside the tank 1.

[0036] Specifically, since a scraper 21 is fixedly connected to the stirring rod 19, one end of the scraper 21 can adhere to the inner wall of the tank 1. Therefore, by the scraper 21 adhering to the inner wall of the tank 1, the stirring rod 19 can scrape away the raw material on the inner wall of the tank 1 during the stirring process, thereby reducing the accumulation of raw material in the tank 1.

[0037] Specifically, a scraper 22 is fixedly connected to the stirring rod 19. The scraper 22 can adhere to the inner wall of the bottom of the tank 1, thereby scraping off the raw material on the inner wall of the bottom of the tank 1 and reducing the amount of raw material adhering to the inner wall of the tank 1.

[0038] The principle of this invention is as follows: The heating wire 7 heats the heat-conducting block 5. Once the heat-conducting block 5 is heated, it heats the water, which then transfers the temperature to the temperature-conducting pipe 6. The temperature-conducting pipe 6 then transfers the temperature to the raw materials, thereby heating the raw materials. Once the water temperature rises to a certain level, the temperature sensor 10 inside the housing 9 senses the water temperature and sends a signal to the control panel 12. The control panel 12 then sends a signal to the heating wire 7 and the liquid pump 8 to stop, thereby controlling the water temperature and indirectly controlling the heating of the raw materials.

[0039] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
