Technical Field

[0001] The utility model relates to the technical field of hoppers, and more specifically, to a hopper for mixing heat-sensitive materials with a temperature control function. Background Art

[0002] Heat-sensitive materials are unstable when exposed to heat. When exposed to heat, they are prone to decomposition, polymerization, oxidation and other deterioration reactions, causing significant economic losses. This should be avoided as much as possible in industrial production. When mixing and adding heat-sensitive materials, a hopper is often required to assist in adding materials. Existing hoppers are often directly installed at the inlet of the mixing equipment through a bucket-shaped cylinder for auxiliary addition.

[0003] The existing hopper has a simple structure and is only equipped with a control valve at the discharge port to control the discharge amount. When heat-sensitive materials are used for auxiliary addition, the internal temperature of the materials is easily increased due to accumulation inside the hopper, thereby causing deterioration reaction and affecting the use effect of the materials. It is inconvenient to cool the materials when storing and adding, and to monitor the temperature of the discharge materials. Therefore, a hopper for mixing heat-sensitive materials with its own temperature control function is proposed. Utility Model Content

[0025] A liquid inlet pipe 7 and a liquid outlet pipe 15 are respectively provided on both sides of the top of the hopper 1, and a rotating rod 8 is provided in the middle of the hopper 1. The two ends of the rotating rod 8 are symmetrically connected to the support frame 10 for rotation. The outer surface of the rotating rod 8 is fixedly connected with a spiral blade 9. Liquid can be injected into the interior of the circulation pipe 4 through the liquid inlet pipe 7, and the liquid is discharged through the liquid outlet pipe 15 to facilitate the circulation of the input cooling liquid for cooling. The rotating rod 8 and the spiral blade 9 are supported by the support frame 10 to improve the stability of the rotating rod 8 and the spiral blade 9. The raw materials entering the interior of the hopper 1 can be diffused to the surroundings through the spiral blade 9 to fit the heat conducting plate 3, thereby improving the cooling effect.

[0026] A support plate 12 is fixedly sleeved in the middle of the hopper 1, and a plurality of support legs 13 are fixedly connected to the bottom of the support plate 12. An auxiliary support rod 14 is fixedly connected between the support legs 13 and the discharge pipe 11. Through the cooperation of the support plate 12, the support legs 13 and the auxiliary support rod 14, the stability of the hopper 1 and the discharge pipe 11 is improved, and it is convenient to use.

[0027] As attached Figure 1 、 2 As shown, the inner cavities of the liquid inlet pipe 7 and the liquid outlet pipe 15 are connected to the two ends of the inner cavity of the circulation pipe 4. The circulation pipe 4 is spirally arranged in the middle of the wall of the hopper 1 and the discharge pipe 11. The coolant circulates through the middle of the circulation pipe 4 through the liquid inlet pipe 7 and the liquid outlet pipe 15, which can cool the heat conduction plate 3.

[0028] As attached Figure 2 、 4 As shown, the circulation pipe 4 corresponds to the limit groove 2, the circulation pipe 4 corresponds to the heat conduction plate 3, and the inner cavity cross-sectional shape of the circulation pipe 4 is set to a quadrilateral, so that the coolant can first cool the heat conduction plate 3 from top to bottom and then from bottom to top, thereby improving the uniformity of cooling and improving the use effect.

[0029] As attached Figure 1 、 2 5, the monitoring end of the temperature monitor 6 passes through the wall of the discharge pipe 11 and extends to the middle of the heat-conducting pipe 5. The heat-conducting pipe 5 and the heat-conducting plate 3 are made of the same material. The structure of the heat-conducting plate 3 is the same as the composition structure of the hopper 1 and the discharge pipe 11.

The raw materials entering the hopper 1 can be diffused by the spiral blade 9 and contact the heat conducting plate 3 on all sides through the guidance of the spiral blade 9, thereby improving the cooling effect.

[0032] The working principle of the utility model is as follows: when in use, the coolant pipe is connected to the liquid inlet pipe 7, and the coolant is input into the interior of the circulation pipe 4 through the liquid inlet pipe 7 by a liquid pump until it flows out from the position of the liquid outlet pipe 15 and flows back to the interior of the cooling box for heat exchange and then recycled;

[0033] After the coolant enters the circulation pipe 4, it will move from top to bottom and then from bottom to top in the middle of the wall of the hopper 1, thereby cooling the heat conducting plate 3. At the same time, the heat conducting plate 3 can cool the raw materials entering the middle of the hopper 1.

[0034] The raw materials entering the hopper 1 are diffused to the surroundings and adhered to the heat conducting plate 3 by the guidance of the spiral blades 9, and slide down the surface of the heat conducting plate 3 to the middle of the discharge pipe 11 and are discharged through the discharge pipe 11. The raw materials adhere to the heat conducting plate 3, which can realize the cooling of the raw materials and facilitate the control of the raw materials to maintain a low temperature. At the same time, the temperature of the discharged raw materials can be monitored by the temperature monitor 6 on the heat conducting pipe 5, which is convenient for monitoring and use;

[0035] Furthermore, the temperature of the cooling liquid input into the circulation pipe 4 can be controlled by the heat exchanger to achieve the effect of regulating the cooling and temperature reduction, thereby realizing the function of temperature control.
