Technical Field

[0001] The utility model relates to the technical field of magnesium stearate production, in particular to a pressure-resistant heating kettle for magnesium stearate. Background Art

[0002] Magnesium stearate is an organic compound, which is a fine white powder without sandiness. It has a slippery feeling when in contact with the skin. It is insoluble in water, ethanol or ether, and is mainly used as a lubricant, anti-adhesive and glidant. It is especially suitable for granulation of oils and extracts. The granules made have good fluidity and compressibility.

[0003] When preparing magnesium stearate, the raw materials need to be put into the heating kettle and heated and stirred. Therefore, after the preparation of magnesium stearate is completed, the pressure inside the heating kettle becomes larger due to heating. At this time, if the heating kettle is not cooled, it is not easy to take out magnesium stearate from the heating kettle, and there is a risk of explosion. In the prior art, the heating kettle lacks a corresponding cooling structure and cannot quickly cool the heating kettle. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Refer to Figures 1 - 3, A magnesium stearate pressure-resistant heating kettle, including a body 1. A cavity is provided in the body 1. A reaction chamber 2 and an annular cooling pipe 3 are provided on the body 1. The reaction chamber 2 is fixedly installed at the upper end of the cavity, and the reaction chamber 2 is used for reacting to generate magnesium stearate, as shown in the attached Figure 2 and the attached Figure 3 As shown, the annular cooling pipe 3 is fixedly installed at the upper end of the cavity. The annular cooling pipe 3 is sleeved outside the reaction chamber 2 to cool the reaction chamber 2 with water and reduce the internal pressure of the reaction chamber 2;

[0022] The body 1 is also provided with a cooling delivery pipe 4, a cooling chamber 5, a mixing chamber 6 and a return pipe 7. The input end of the cooling delivery pipe 4 is fixedly connected to the annular cooling pipe 3. The cooling chamber 5 and the mixing chamber 6 are both fixedly installed at the lower end of the cavity, and the output end of the cooling delivery pipe 4 is communicated with the cooling chamber 5, so that the water in the annular cooling pipe 3 flows into the cooling chamber 5 through the cooling delivery pipe 4, and the input end and the output end of the return pipe 7 are respectively fixedly connected to the mixing chamber 6 and the annular cooling pipe 3, so that the water in the mixing chamber 6 flows into the reaction chamber 2 through the return pipe 7.

[0023] The body 1 is composed of a frustum and a hemisphere. At the same time, the body 1, the cooling chamber 5 and the mixing chamber 6 are all made of materials with a relatively large thermal conductivity. The reaction chamber 2 is a spherical structure. The upper end of the body 1 is respectively fixedly connected to a feed pipe 8 and a pressure relief valve 9, and the lower ends of the feed pipe 8 and the pressure relief valve 9 are both communicated with the reaction chamber 2. The raw materials are put into the reaction chamber 2 through the feed pipe 8, and the pressure relief valve 9 is used to prevent the internal pressure of the reaction chamber 2 from exceeding the limit pressure.

[0024] At the same time, a discharge pipe 10 is fixedly installed at the lower end of the reaction chamber 2, and the discharge pipe 10 extends outside the body 1. After the magnesium stearate is prepared, the magnesium stearate can be discharged through the discharge pipe 10. A driving motor is installed at the outer bottom end of the reaction chamber 2, and a rotating shaft 11 is rotatably installed at the inner bottom end of the reaction chamber 2. The output end of the driving motor is connected to the rotating shaft 11, and a stirring blade 12 is fixedly sleeved on the rotating shaft 11. Then, the stirring blade 12 is rotated through the driving motor to stir the raw materials.

[0025] A cold water pipe 14 and a connecting pipe 16 are respectively fixedly connected to the mixing chamber 6. The cold water pipe 14 extends to the outer end of the body 1, and the connecting pipe 16 is communicated with the cooling chamber 5. Solenoid valves 13 are fixedly installed on both the return pipe 7 and the connecting pipe 16. When the water flows from the cooling delivery pipe 4 to the cooling chamber 5, due to the relatively large thermal conductivity of the cooling chamber 5, the heat energy of the water is transferred to the outside of the body 1. Then, the solenoid valve 13 of the connecting pipe 16 is opened to mix the water with the cold water in the mixing chamber 6 to further cool the water. Then, the solenoid valve 13 of the return pipe 7 is started to let the water flow into the annular cooling pipe 3;

[0026] As shown in the attached Figure 2 and the attached Figure 3As shown, since the heat dissipation holes 15 are opened on the body 1 and the heat dissipation holes 15 are connected to the cavity, when the water flows to the cooling delivery pipe 4, the heat energy in the cooling delivery pipe 4 is discharged through the heat dissipation hole pipe 15. At the same time, the cooling delivery pipe 4, the return pipe 7, the cold water pipe 14, and the connecting pipe 16 are all installed with a one-way valve, so that the water flows in the order of the cold water pipe 14, the return pipe 7, the annular cooling pipe 3, the cooling delivery pipe 4 and the connecting pipe 16.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] First, the raw material is put into the reaction chamber 2 from the feed pipe 8, and then the rotating shaft 11 is started, so that the rotating shaft 11 drives the stirring blade 12 to stir, so that the raw material reacts. After the reaction is completed, cold water is allowed to flow from the cold water pipe 14 to the mixing chamber 6, and then from the reflux pipe 7 to the annular cooling pipe 3. At this time, the flowing cold water takes away the heat energy of the reaction chamber 2, and flows to the cooling conveying pipe 4, and then flows to the cooling chamber 5 for cooling;

[0029] Then, the solenoid valve 13 of the connecting pipe 16 is opened to allow the water in the cooling chamber 5 to mix with the cold water to further cool the water temperature, and then the solenoid valve 13 of the reflux pipe 7 is opened to allow the water to continue to flow from the reflux pipe 7 to the annular cooling pipe 3 and cool the reaction chamber 2.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
