Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a reaction vessel stirring and sealing structure. Background Technology

[0002] A reaction vessel is a common piece of chemical equipment, widely used in chemistry, pharmaceuticals, food, materials, and other fields to carry out various chemical reactions or physical processes. When a chemical reaction occurs in a reaction vessel, the raw materials are first added to the vessel in a specific ratio. Then, a stirring device is used to thoroughly mix the raw materials. Stirring breaks the surface tension of the liquid, increases the contact area between reactants, promotes molecular collisions, and accelerates the reaction rate.

[0003] A reaction vessel typically includes a vessel body and a stirring device. Some vessels are equipped with heating or cooling systems. The vessel body has a feed inlet, which is a hollow cylinder. During feeding, the feeding terminal, such as the feed pipe or the discharge port of the elevator, is connected to the feed inlet. However, the feeding terminal and the feed inlet cannot be completely covered. Furthermore, when the feeding terminal is removed after feeding is completed, the feed inlet will be exposed, allowing air to enter and affecting the subsequent reaction. There is room for technical improvement. Utility Model Content

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1, in conjunction with Appendix Figure 1 A stirring and sealing structure for a reaction vessel includes a vessel body 1. A discharge port 2 is connected to the middle of the bottom surface of the vessel body 1. A material valve is provided inside the discharge port 2 to control the opening and closing of the discharge port 2. Several support feet 3 are provided circumferentially on the bottom surface of the vessel body 1. Anti-slip pads 4 are provided on the bottom surface of each support foot 3 to improve the stability of the vessel body 1.

[0026] Combined with appendix Figure 3 The vessel body 1 has a double-layer structure, and an electric heating wire 6 is coiled between the two layers. When necessary, the temperature inside the vessel body 1 can be increased to promote the reaction.

[0027] Combined with appendix Figure 1 , 2 The vessel body 1 is detachably equipped with a cover 5. Specifically, the upper end of the vessel body 1 is equipped with a flange ring, and the cover 5 can be detachably connected to the vessel body 1 through the flange ring and bolts. The cover 5 is equipped with a one-way vent valve 19, which can release gas through the one-way vent valve when the gas pressure inside the reactor increases, thereby maintaining gas pressure balance.

[0028] Combined with appendix Figure 1 , 2 The vessel body 1 is equipped with a drive motor 6 and a reducer. The output end of the reducer is equipped with a rotating shaft 7. The rotating shaft 7 extends into the vessel body 1 and is equipped with stirring blades for mixing and stirring the raw materials in the vessel body 1. The vessel body 1 is equipped with a through groove, and a sealed bearing that can be connected to the rotating shaft 7 is installed in the through groove. The sealed bearing supports and assists the rotation of the rotating shaft 7, and improves the sealing performance at the through groove. To improve the sealing performance, lubricant can be applied to the sealed bearing to achieve a liquid seal.

[0029] Combined with appendix Figure 3 The vessel body 1 is provided with a fixing ring 17, and a sealed bearing 2 that can be connected to the rotating shaft 7 is provided on the inner side of the fixing ring 17; support rods 18 are provided on both sides of the fixing ring 17, and the other end of the support rods 18 is fixedly connected to the lower end of the vessel body 1 at the non-center position; the fixing ring 17 and the support rods 18 can restrict the lower end of the rotating shaft 7 to the non-center position to avoid conflict with the discharge port 2.

[0030] Combined with appendix Figure 2 It also includes a lid sealing structure; including a sealing ring 8 provided under the lid 5, which can extend into the upper end of the vessel body 1 and contact the inner wall to improve the sealing performance; several arc-shaped plates 9 are provided circumferentially under the lid 5 and outside the sealing ring 8, and an arc-shaped groove 10 is provided at the upper end of the vessel body 1 to be inserted into the arc-shaped plates 9. The arc-shaped plates 9 and the arc-shaped groove 10 can improve the connection stability between the vessel body 1 and the lid 5, and are less likely to cause relative displacement and deflection of the vessel body 1 and the lid 5 due to the vibration of the drive motor and related components, so as to avoid affecting the sealing performance; the arc-shaped plates 9 include inner and outer layers, the inner layer is a metal plate, and the outer layer is a rubber layer. The outer layer of the rubber layer is pressed into contact with the arc-shaped groove 10 to increase the friction and improve the insertion stability;

[0031] Combined with appendix Figure 1 , 2 4, 5, also include a feeding sealing structure; including a feeding cylinder 11, the upper end of which is detachably connected to a metal cover plate 12 via a flange, which can protect the feeding cylinder 11 by installing the metal cover plate 12; the longitudinal section of the feeding cylinder 11 is stepped, with a larger inner diameter in the upper part to expand the feeding space;

[0032] Based on the above structure, an annular baffle 13 is provided inside the feed cylinder 11 near its upper end. The thickness of the annular baffle 13 gradually increases from the middle to the outer side, forming an inverted umbrella shape on the upper surface of the annular baffle 13 to avoid dead zones for raw materials and prevent them from falling. The bottom surface of the annular baffle 13 is horizontal. A hollow cylindrical feed hopper is fixedly connected below the annular baffle 13, and the raw material falls from the annular baffle 13 into the feed hopper. A hollow cylinder 14 is movable at the upper end inside the feed hopper, with the lower end open and the upper end sealed. A hollow cylinder 2 15 is fixed at the lower end inside the feed hopper. The lower end is blocked and the upper end is open; the upper end of the second hollow cylinder 15 extends into the first hollow cylinder 14, and a spring 16 is fixed between the lower end of the second hollow cylinder 15 and the upper end of the first hollow cylinder 14; thus, during feeding, the impact of the raw material presses down the upper end of the first hollow cylinder 14, and the raw material can smoothly enter the feeding hopper. When the pressure is insufficient in the later stage of feeding, the first hollow cylinder 14 gradually moves upward under the reset of the spring 16 until its upper end blocks the annular baffle 13, which can close the feeding channel of the inner ring of the annular baffle 13 in time, reduce the time of closing the feeding channel, and prevent air and impurities from entering;

[0033] In addition, the upper end of the hollow cylinder 14 is conical. The hollow cylinder 14 descends to allow the raw materials to enter the feeding hopper, preventing the raw materials from accumulating and stagnating on the upper surface of the hollow cylinder 14.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
