Description

Technical Field

[0001] The utility model belongs to the field of liquid feeding tanks, and in particular relates to a homogeneous heat transfer liquid feeding tank. Background Art

[0002] In the field of materials and chemical operations, multiple components need to be mixed, and feeding tanks are usually used. Feeding tanks in the existing technology, especially large feeding tanks, often cause the materials to solidify due to the large amount of raw materials in the tank, long feeding time, and ambient temperature, thereby blocking the feeding channel. In addition, the feeding tanks store a wide variety of materials with different properties. For heat-sensitive substances, local heating and uneven heat transfer often lead to damage to the material properties and even produce a series of defective products. For acidic and alkaline substances, coupled with a high temperature environment, it will accelerate the corrosion of the feeding tank, greatly reducing the service life of the feeding tank.

[0003] Therefore, a new type of homogeneous heat transfer liquid feeding tank is needed. Utility Model Content

[0004] In order to solve the above problems, the utility model discloses a homogeneous heat transfer liquid feeding tank.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0006] A homogeneous heat transfer liquid feeding tank comprises a tank body, the top of the tank body is connected to a material inlet pipe, and the bottom of the tank body is connected to a material outlet pipe, a double-layer hollow heat-conducting lining is attached to the inner wall of the tank body, a heat-conducting coil is fixed to the inner side of the double-layer hollow heat-conducting lining through a support frame, and heat-conducting liquid circulates through the double-layer hollow heat-conducting lining and the heat-conducting coil respectively, a reducer is installed on the top of the tank body, the output end of the reducer is coaxially fixedly connected to a stirring spindle, and the stirring spindle extends into the center of the heat-conducting coil, and the input end of the reducer is coaxially fixedly connected to a motor.

[0007] As a preferred technical solution of the present invention, the stirring main shaft and the heat conducting coil are coaxial.

[0008] As a preferred technical solution of the present invention, the stirring main shaft is equipped with at least one stirring blade.

[0009] As a preferred technical solution of the present invention, the inner layer of the double-layer hollow thermally conductive lining is made of high thermally conductive plastic, and the outer layer is made of low thermally conductive plastic.

[0010] As an optimal technical solution of the present invention, a lining liquid inlet pipe penetrating the tank body is provided at the bottom of the double-layer hollow thermal conductive lining, and a lining liquid outlet pipe penetrating the tank body is provided at the top of the double-layer hollow thermal conductive lining.

[0011] As a preferred technical solution of the present invention, the shell of the heat-conducting coil is made of high-thermal-conductivity plastic.

[0012] As a preferred technical solution of the present invention, a coil liquid inlet pipe extending from the bottom of the heat-conducting coil and penetrating the tank body is provided, and a coil liquid outlet pipe extending from the top of the heat-conducting coil and penetrating the tank body is provided.

[0013] The beneficial effects of the utility model are:

[0014] 1. The use of a double-layer hollow thermal lining and thermal coils achieves thermal insulation and homogeneous heating of the tank body, effectively preventing the instantaneous temperature rise caused by electromagnetic heating from damaging the performance of the material in the tank, while reducing the large amount of heat loss caused by metal thermal conduction. The double-layer hollow thermal lining cleverly utilizes the heat transfer of thermally conductive plastics and the thermal insulation properties of ordinary plastics to achieve a complex organic combination of thermal insulation and heat transfer, reducing the probability of clogging of the feeding channel;

[0015] Second, plastics have many advantages such as lightness, easy molding, corrosion resistance and electrical insulation, which can effectively solve the above-mentioned problems encountered by feeding tanks. While ensuring homogeneous heat transfer in feeding tanks, they also provide more optionality, functionality, energy saving and environmental protection for production operations.

[0016] Third, this feeding tank uses plastic for its inner lining and heating coils. Compared to traditional metals, which require special treatment to achieve corrosion resistance, plastic inherently possesses excellent resistance to acid and alkali corrosion. Furthermore, the acidity and alkalinity of a substance increase rapidly at high temperatures, accelerating the risk of scaling and corrosion in the feeding tank. This limits the application of many metal feeding tanks and shortens their service life. Using thermally conductive plastic not only expands the application range of the feeding tank but also extends the equipment's service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] See also Figure 1 A homogeneous heat transfer liquid feeding tank includes a tank body 2, the top of the tank body 2 is connected to a material inlet pipe 14, and the bottom of the tank body 2 is connected to a material outlet pipe 16. An ear seat 7 for supporting and fixing the feeding tank is provided on both sides of the tank body 2, which helps to improve the stability of the equipment and improve the risk resistance of the equipment. A double-layer hollow heat-conducting lining 3 is attached to the inner wall of the tank body 2. A heat-conducting coil 4 is fixed to the inner side of the double-layer hollow heat-conducting lining 3 through a support frame 6. The double-layer hollow heat-conducting lining 3 and the heat-conducting coil 4 respectively circulate heat-conducting liquid to heat the material in the tank. The heat-conducting liquid is one of water and heat-conducting oil. According to the different formula products, the corresponding operating temperature is selected. Alkylbenzene-type heat-conducting oil is often used as the heat-conducting liquid to provide more refined and professional services for production operations. A reducer 11 is installed on the top of the tank body 2. The output end of the reducer 11 is coaxially fixedly connected to the stirring main shaft 5, and the stirring main shaft 5 extends into the center of the heat-conducting coil 4. The input end of the reducer 11 is coaxially fixedly connected to the motor 12. The housing of the reducer 11 is fixedly connected to the housing of the motor 12, and the output shaft of the motor 12 is coaxially fixedly connected to the input end of the reducer 11. The outer rotating sleeve of the stirring main shaft 5 is provided with a bracket assembly 10. The bottom of the bracket assembly 10 is fixedly connected to the upper cover of the tank body 2, and the top of the bracket assembly 10 is fixedly connected to the housing of the reducer 11.

[0022] An observation manhole and a liquid level gauge are respectively provided on both sides of the tank body 2. The observation manhole is installed about 1.2m to 1.5m from the ground for easy observation. The liquid level gauge can be a magnetic flip level gauge, which is installed on the side of the feeding tank to avoid the material inlet and outlet, reducing the impact of local changes in the material on the liquid level accuracy.

[0023] The stirring shaft 5 is coaxial with the heat conducting coil 4. The stirring shaft 5 is equipped with at least one stirring blade 1. In the embodiment of the accompanying drawings, the stirring shaft 5 is equipped with two stirring blades 1, and the lower stirring blade 1 is about 3 to 5 cm vertically away from the bottom of the tank body 2. The stirring blade 1 and the stirring shaft 5 form a stirring system. The stirring blade 1 stirs up and down, so that the additive in the tank body 2 flows up and down and can be heated in time, avoiding local overheating or uneven heating of the additive during the feeding process.

[0024] Motor 12 is electrically connected to an electrical control cabinet 13. The electronic control system, consisting of the reducer 11, motor 12, and electrical control cabinet 13, is connected to the stirring system, temperature sensor, and liquid level gauge. This system effectively monitors the temperature and liquid level in tank 2, allowing for timely adjustment of stirring, heating, and material feeding parameters. The liquid level gauge also controls material feeding, selecting the appropriate stirring speed based on material viscosity. The temperature sensor is flange-mounted at a height of 1.2 to 1.5 meters from the operating floor.

[0025] The inner layer of the double-layer hollow thermally conductive liner 3 is a 1.5cm thick, high-thermal-conductivity plastic that transfers heat from the high-temperature fluid within the double-layer hollow thermally conductive liner 3 to the contents of the tank body 2. Its outer layer, a 2cm thick, low-thermal-conductivity plastic, adheres to the inner wall of the tank body 2, providing insulation and effectively preventing heat loss and pipe blockage caused by a drop in ambient temperature, providing a higher operating temperature (80-160°C). A liner liquid inlet pipe 15 is provided at the bottom of the double-layer hollow thermally conductive liner 3, extending through the tank body 2, and a liner liquid outlet pipe 9 is provided at the top of the double-layer hollow thermally conductive liner 3, extending through the tank body 2.

[0026] The outer shell of the heat-conducting coil 4 is made of high-thermal-conductivity plastic with a diameter of 3 cm. A coil liquid inlet pipe 17 extending from the bottom of the heat-conducting coil 4 passes through the tank body 2, and a coil liquid outlet pipe 8 extending from the top of the heat-conducting coil 4 passes through the tank body 2. The base material of the heat-conducting coil 4 is one or more of polypropylene (PP), polycarbonate (PC), polystyrene (PS) and polyamide (PA). The thermally conductive plastic base material is selected according to the operating temperature required by the formulated product. Compared with metal linings and electric heating wires, thermally conductive plastics are lighter, which helps to reduce the weight of the overall structure and have better formability. They can be processed by injection molding, extrusion and other processes to adapt to customized designs of complex shapes. In addition, thermally conductive plastics have better corrosion resistance and insulation, which greatly improves the service life and safety of the product.

[0027] Working principle: When in use, raw materials are added to the tank body 2 through the material inlet pipe 14, and heat-conducting liquid is added to the double-layer hollow heat-conducting lining 3 and the heat-conducting coil 4 through the lining liquid inlet pipe 15 and the coil liquid inlet pipe 17 respectively. The high thermal conductivity plastic inner wall of the lining liquid inlet pipe 15 can effectively and evenly transfer heat to the raw materials in the tank body 2 to avoid local overheating and damage of the material. The low thermal conductivity plastic outer wall of the lining liquid inlet pipe 15 can effectively reduce the transfer of materials and play a role in heat preservation and heat insulation, avoiding the material in the tank body 2 from caking due to environmental heat dissipation and clogging the pipeline. At the same time, the high thermal conductivity plastic heat-conducting coil 4 evenly arranged inside the tank body 2 allows the raw materials in the tank body 2 to be heated evenly, improving the overall heat exchange efficiency and the uniformity of raw material heating. In addition, the stirring of the stirring spindle 5 can effectively transfer heat to the material in the tank body 2, avoiding bubbles and uneven mass transfer and heat transfer during the feeding process. The tank body 2 is provided with a manhole, a temperature sensor and a liquid level meter, which can monitor the quality, processing effect and liquid level of the raw materials in the tank body 2 in real time so as to make timely adjustments.
