Description

Technical Field

[0001] This utility model relates to the field of material temperature control technology, and in particular to an adjustable material temperature control device. Background Technology

[0002] Material temperature control devices are equipment used to maintain a specific temperature and are widely used in industries such as chemical, food, and pharmaceutical. These include reaction storage tanks. In some material mixing reactions, it is necessary to keep the reaction storage tanks at a constant temperature to prevent the internal reactants from deteriorating. Adjustable material temperature control devices improve the efficiency and safety of material processing in various industries through precise temperature control technology, and are one of the indispensable pieces of equipment in modern industry.

[0003] Existing adjustable material temperature control devices are not convenient for maintaining a constant temperature for the internal materials during actual use, as excessively low temperatures can easily lead to material deterioration and damage.

[0004] A search of existing patents revealed a heating and temperature control device for viscous materials (Publication No.: CN221223001U). This device includes an outer cylinder containing an inner cylinder. The upper and lower ends of the outer cylinder are sealed, and a gap exists between the outer and inner cylinders. The lower end of the inner cylinder has a funnel-shaped discharge end extending from the lower end of the outer cylinder, with the lower end serving as a discharge port. This discharge port is connected to a material dispersing device via a discharge pipe. The upper end of the inner cylinder has a feed inlet connected to a material dispersing device via a feed pipe. The upper and lower ends of the outer cylinder have a heat medium outlet and a heat medium inlet, respectively. This design is structurally reliable. By injecting constant-temperature water into the gap between the inner and outer cylinders, the outer layer of constant-temperature water provides the heat source, resulting in more uniform heating of the viscous material within the inner cylinder.

[0005] Although the aforementioned patent achieves the goal of injecting constant-temperature water into the gap between the inner and outer cylinders, and using the outer constant-temperature water as a heat source to heat the viscous material inside the inner cylinder, resulting in more uniform heating, it is not convenient to adjust the internal air pressure of the material temperature control device. Excessive internal air pressure can damage the inner liner structure.

[0006] Therefore, it is necessary to invent an adjustable material temperature control device to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides an adjustable material temperature control device, which has the following beneficial effects:

[0019] 1. This adjustable material temperature control device, through the arrangement of a spiral heat-conducting pipe, conveying components, and sensing components, heats the water inside the tank when the heating base is activated. The water pump then draws out the heated water and delivers it to the spiral heat-conducting pipe via a connecting pipe. Since the spiral heat-conducting pipe is in close contact with the outside of the inner tank, it transfers the heat of the water to the inside of the inner tank, thus keeping the material inside warm. Simultaneously, when the temperature sensor on the top cover detects that the internal temperature exceeds the set value, it sends a signal to the controller. The controller then stops the heating base, thereby achieving the effect of maintaining a constant temperature for the internal material, preventing the material from deteriorating or being damaged due to excessively low temperatures, and improving the heat preservation capacity of the adjustable material temperature control device.

[0020] 2. This adjustable material temperature control device, through the setting of the pressure relief component, generates gas during use due to the mixing of various materials inside the inner liner, leading to an increase in internal air pressure. This gas pushes the piston, which is blocked at the narrow end of the pressure relief pipe, causing it to move upwards to the thicker middle end. The piston then pushes the sliding rod to slide on the positioning plate, causing the telescopic spring to deform and contract. The gas passes around the piston from both sides and is discharged. When the internal air pressure returns to normal, the telescopic spring returns to its original deformation, pushing the piston and sealing the pressure relief pipe. To adjust the internal air pressure, the limit nut on the sliding rod is rotated, reducing the length of the sliding rod and adjusting the telescopic spring force. This achieves the effect of adjusting the internal air pressure of the material temperature control device, preventing excessive internal pressure from damaging the inner liner structure and improving the service life of the device.

Excessive air pressure damages the structure of the inner liner 2, increasing the service life of the adjustable material temperature control device. The conveying component 4 includes a connecting pipe 401 that passes through one end of the spiral heat-conducting pipe 3. One end of the connecting pipe 401 is connected to a water pump 402, and one end of the water pump 402 is connected to a water tank 403. The sensing component 7 includes a temperature sensor 701 that is fixedly connected to the top of the top cover 6. One end of the temperature sensor 701 is electrically connected to a controller 702 via a power cord. The pressure relief component 9 includes a positioning piece 901 that is sleeved inside the pressure relief pipe 8. A sliding rod 902 is slidably connected inside the positioning piece 901. A piston 903 is fixedly connected to the bottom of the sliding rod 902. A telescopic spring 904 is fixedly connected to the top of the piston 903. A limit nut 905 is threadedly connected to the surface of the sliding rod 902.

[0029] A fixing post 10 is fixedly connected to one side of the water tank 403, and a connecting piece 11 is fixedly connected to one end of the fixing post 10. The connecting piece 11 serves to fix the tank to the surface of the outer cylinder 1.

[0030] A drive motor 12 is fixedly connected to the top of the top cover 6, and a rotating rod 13 is fixedly connected to the bottom of the drive motor 12. The rotating rod 13 drives the stirring rod 15 to rotate.

[0031] A motor housing 14 is fitted onto the surface of the drive motor 12, and several sets of stirring rods 15 are fixedly connected to the surface of the rotating rod 13. The stirring rods 15 are used to stir the internal materials.

[0032] The bottom of the outer cylinder 1 is fixedly connected to a discharge pipe 16, and one end of the discharge pipe 16 is provided with an opening and closing valve 17. The opening and closing valve 17 facilitates the discharge of materials.

[0033] A pressure gauge 18 is fixedly installed on the top of the top cover 6, and a support column 19 is fixedly connected to the bottom of the outer cylinder 1. The support column 19 serves to support the outer cylinder 1.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When in use, start the heating base 5 to heat the water inside the water tank 403, then start the water pump 402 to extract the heated water and transport it to the spiral heat conduction pipe 3 through the connecting pipe 401. Since the spiral heat conduction pipe 3 is close to the outside of the inner liner 2, it transfers the heat of the water to the inside of the inner liner 2 to keep the material inside the inner liner 2 warm. At the same time, when the temperature sensor 701 on the top cover 6 detects that the internal temperature is greater than the set value, it sends a signal to the controller 702, and the controller 702 controls the heating base 5 to stop heating.

[0038] The second step: During use, due to the mixing of various materials inside the inner liner 2, corresponding gas will be generated, which will increase the internal air pressure. The gas pushes the piston 903, which is blocked at the thin end of the pressure relief pipe 8, so that the piston 903 moves up to the thick end in the middle and pushes the sliding rod 902 to slide on the positioning plate 901. Then the telescopic spring 904 is deformed and contracted under force, and the gas passes around the piston 903 from both sides and is discharged.

[0039] Third step: When the internal air pressure is normal, the telescopic spring 904 returns to its original deformation and pushes the piston 903 to seal the pressure relief pipe 8. At the same time, when it is necessary to adjust the internal air pressure, rotate the limit nut 905 on the sliding rod 902 and adjust the elasticity of the telescopic spring 904 by reducing the length of the sliding rod 902.
