Technical Field
[0001] The utility model relates to the technical field of reaction kettle components, in particular to a novel liquid material feeding pipe for a reaction kettle. Background Art
[0002] Reactor is a kind of equipment widely used in the fields of chemistry, petroleum, medicine, food, etc. It is a container for physical or chemical reactions. In the process of chemical production, it is often necessary to use a dripping device to drip solution into the reactor as part of the process.
[0003] In the prior art, the feeding tube of the dripping device is generally a pipe with two ends open, and the relative position of the discharge port of the pipe and the reactor is fixed. The solution added each time basically falls on the same position in the reactor, and the solution added is mixed with the solution in the reactor by stirring the reactor. However, in this way, the material flowing out of the feeding tube is only distributed in one area, and it takes a long time to be evenly distributed in the entire reactor in the reactor. This will cause an excess of a certain material in some positions in the reactor in a short period of time, while the material in other parts is insufficient, thereby affecting the product quality, and in severe cases may cause quality accidents and safety accidents. Furthermore, when the liquid material is a heat-sensitive material or a material with self-polymerization properties, the liquid material will decompose or self-polymerize when heated in the feeding tube, resulting in a significant reduction in product quality and even the generation of waste products.
[0004] Based on the above reasons, the utility model designs a new type of liquid material feeding pipe for the reactor, which can quickly mix the incoming liquid material with the material in the reactor, and prevent the liquid material from being heated by combining the sleeve-type feeding pipe with the cooling medium, thereby improving production efficiency and product quality and reducing safety hazards.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a novel liquid material feeding pipe for a reactor, comprising a liquid feeding pipe body and a high-efficiency mixer connected by threads or flanges, the outer layer of the liquid feeding pipe body is an outer shell, the center of the liquid feeding pipe body is an inner tube, the outer shell and the inner tube form three independent cavities, the top of the inner tube is a material inlet 1, the top of the cavity formed between the inner tube and the outer shell is respectively provided with a medium inlet and a medium outlet, and the top of the outer shell is provided with a receiving plate with screw holes; the top of the high-efficiency mixer is provided with a material inlet 2 connected to the inner tube, the lower part of the material inlet 2 is connected with a throat, and the two sides of the throat are respectively connected with a trumpet-shaped inlet expansion section and an outlet expansion section.
[0007] The small end of the inlet expansion section is connected to the throat, and the small end of the outlet expansion section is connected to the throat.
[0008] The diameter of the large end ports of the inlet expansion section and the outlet expansion section is 50-100 mm, and the length of the inlet expansion section and the outlet expansion section is 100-200 mm.

[0018] The utility model is now further described with reference to the accompanying drawings.
[0019] See also Figures 1-2 The utility model provides a new type of liquid material feeding pipe for a reactor, comprising a liquid feeding pipe body and a high-efficiency mixer connected by threads or flanges, the outer layer of the liquid feeding pipe body is an outer shell 1, the center of the liquid feeding pipe body is an inner tube 2, the outer shell 1 and the inner tube 2 form three independent cavities, the top of the inner tube 2 is a material inlet 6, the top of the cavity formed between the inner tube 2 and the outer shell 1 is respectively provided with a medium inlet 4 and a medium outlet 5, and the top of the outer shell 1 is provided with a receiving plate 3 with screw holes; the top of the high-efficiency mixer is provided with a material inlet 2 7 connected with the inner tube 2, the lower part of the material inlet 2 7 is connected with a throat 9, and the two sides of the throat 9 are respectively connected with a trumpet-shaped inlet expansion section 8 and an outlet expansion section 10.
[0020] The small end of the inlet expansion section 8 is connected to the throat 9 , and the small end of the outlet expansion section 10 is connected to the throat 9 .
[0021] The diameter of the large end ports of the inlet expansion section 8 and the outlet expansion section 10 is 50-100 mm, and the length of the inlet expansion section 8 and the outlet expansion section 10 is 100-200 mm.
[0022] The diameter of the throat pipe 9 is 20-40 mm, and the length is 50-100 mm.

[0024] The inner diameter of the inner tube 2 is consistent with that of the material inlet 7.
[0025] Working principle:
[0026] The utility model does not require excessive debugging. Liquid materials flow in through the main pipe 2 in the liquid feeding pipe body. There is a cooling medium between the main pipe 2 and the outer shell 1. The liquid materials in the inner pipe 2 are affected by the cooling medium in the outer cavity to prevent the liquid materials from being heated in the inner pipe 2 and thus decomposing or self-aggregating. The cooling medium enters from the medium inlet 4 and flows out from the medium outlet 5 to form a circulation process, which continuously cools the liquid materials.
[0027] At the same time, under the stirring action of the reactor, the reaction materials in the reactor enter from the inlet expansion section 8 of the high-efficiency mixer and the flow rate inside it gradually increases, forming a high-speed flow and generating negative pressure in the throat section 9. After the liquid material enters the high-efficiency mixer through the inner tube 2 and the material inlet 2 7, the liquid material is sucked into the throat section 9 and quickly mixed with the reaction materials entering the high-efficiency mixer, and continues to mix in the outlet expansion section 10 of the high-efficiency mixer. After flowing out of the high-efficiency mixer, a larger mixing surface is formed, and it can be quickly mixed evenly in the reactor.

[0030] The utility model solves the problems in the prior art that the liquid material cannot be quickly diffused into the reaction material, resulting in low efficiency and affecting product quality, as well as the problem that the liquid material further deteriorates in product quality due to its thermal decomposition or self-aggregation. The utility model uses three cavities formed by a sleeve in the liquid material feeding pipe, and the liquid material can quickly enter the high-efficiency mixer in the reactor through the inner pipe in the middle, and quickly mix with the reaction material and disperse in the material; through the influence of the cooling medium circulating in the cavities on both sides of the inner pipe, the liquid material can avoid decomposition or self-aggregation due to heat, thereby not affecting the product quality. In addition, the liquid material is efficiently mixed and dispersed with the material, which improves the product quality and production efficiency as a whole, reduces potential safety risks, and has a high application value.
