Description

Technical Field

[0001] The invention relates to the field of chemical production equipment, in particular to a mixing reactor for preparing potassium perchlorate. Background Art

[0002] Potassium perchlorate, an inorganic compound with the chemical formula KClO₄, is a colorless or white crystalline powder. It is soluble in water but insoluble in ether and ethanol. It is more stable than potassium chlorate and decomposes into potassium chloride and oxygen at its melting point. It can be used as a smoke generator, igniter, oxidizer, and chemical analysis reagent.

[0003] The industry generally adopts the traditional production process of double decomposition to prepare potassium perchlorate. This is because the sodium chlorate generated in the process of producing potassium perchlorate can be recycled, there is no waste discharge, and it has the advantages of being more environmentally friendly, low cost, and high product quality. However, there are the following problems:

[0004] The double decomposition method is commonly used in the preparation of potassium perchlorate, which offers advantages such as environmental friendliness, low cost, and high product quality. However, this process typically involves highly corrosive media and high-temperature reaction environments, placing extremely high demands on the corrosion resistance, structural stability, and uniform and efficient temperature control of the reactor tank. Existing reactors, when subjected to long-term exposure to corrosive media and high temperatures, suffer from short lifespans, high maintenance costs, and inaccurate and uneven temperature control. This is especially true in large-capacity tanks, where efficient and uniform heat transfer is difficult to achieve, impacting product quality and production stability. Summary of the Invention

[0005] Technical problems solved

[0006] In view of the shortcomings of the prior art, the present invention provides a mixed reactor for preparing potassium perchlorate, which solves the following problems:

[0007] 1. The existing potassium perchlorate production mixing tank still requires personnel to be on-site for supervision. Since potassium perchlorate production is a relatively dangerous process, if a safety accident occurs, the safety of people on site cannot be protected and the lives of people cannot be guaranteed;

[0008] 2. The existing raw material mixing of potassium perchlorate production still adopts blade stirring. Due to the fluid characteristics of the blade itself, the mixture will produce regular movement during the stirring process, affecting the mixing efficiency. The use of multiple blades has improved it, but it is not reasonable to arrange a large number of blades for large tanks. The use of variable speed can also partially solve the problem, but the construction cost of frequency conversion equipment is relatively high, which is a heavy burden on enterprises.

[0009] Technical Solution

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions: A mixing reactor for preparing potassium perchlorate, comprising a support frame and a tank assembly, wherein the tank assembly includes a tank bracket bolted to the support frame, the tank assembly also includes a tank shell, and the tank bracket is welded to the outer surface of the tank shell, an inner tank body is embedded in the inner cavity of the tank shell, a cavity is formed between the tank shell and the inner tank body, a heat pipe is embedded in the cavity, the heat pipe is spirally wrapped around the surface of the inner tank body, both ends of the heat pipe are connected to a temperature control device, and a top cover assembly is provided on the top of the tank shell.

[0011] Preferably, the heat pipe is made of corrosion-resistant and high thermal conductivity material.

[0012] Preferably, the temperature control device includes a boiler, a condenser or a constant temperature device.

[0013] Preferably, the inner tank body is made of a special material resistant to strong corrosion, and the outer tank body is made of a high-strength structural material.

[0014] Beneficial effects

[0015] The present invention provides a mixing reactor for preparing potassium perchlorate, which has the following beneficial effects:

[0016] 1. The present invention adopts an external pipeline to pump different auxiliary materials directly into the inner tank body through a pump. According to the different addition amounts, feeding nozzles of different calibers can be selected. Since all are pumped, this link can be completely or basically completely separated from manual control, avoiding the occurrence of production safety accidents. Through electronic adjustment, multiple different tanks can be controlled to produce synchronously, which can realize unmanned operation and avoid the situation where operators are required to operate on site and cannot guarantee personal safety in the event of safety accidents.

[0017] 2. The homogenizing holes opened on the surface of the stirring blade of the blade assembly of the present invention can reduce the fluid resistance during the stirring process, and after the surface of the stirring blade is evenly pierced, the thin walls formed between the holes have a cutting effect on the mixture, thereby destroying the regular flow of objects and accelerating the mixing efficiency. In addition, an impact groove is opened on the surface of the stirring blade. During the stirring process, the mixture can be impacted by the impact force of the rotating blade and then impact the objects in the groove area to form a flow channel along both sides of the impact groove, thereby further impacting the regular movement of the objects, improving the mixing efficiency, and further reducing the mixing time. At the same time, the use of blades with a mechanized fluid structure can avoid the high cost of using frequency conversion equipment and reduce the burden on enterprises.

The stirring assembly 5 includes a stirring main shaft 506, an active motor 501 and a quick-release flange 507 engaged with the top cover assembly 403. The quick-release flange 507 is a double-layer structure. The upper layer and the top cover body 4031 are positioned by bearings, and the lower layer and the stirring main shaft 506 are sleeved for positioning. The blade assembly 505 is installed in the middle and bottom of the stirring main shaft 506. The surface of the stirring main shaft 506 The surface is sleeved with a blade assembly 505, which includes a mounting clamp 5051 connected to the stirring main shaft 506 for positioning. The mounting clamp 5051 is symmetrically mounted with stirring blades 5052 on both sides. The surface of the stirring blade 5052 is evenly provided with homogenizing holes 5053. The homogenizing holes 5053 are polygonal holes, and the edges of the force-bearing surfaces of the homogenizing holes 5053 are deburred. The cross-sectional shape of the impact groove 5054 is a structure that is deep in the middle and gradually shallow on both sides, and each group of the impact groove 5054 has 3-5 notches. The surface of the stirring blade 5052 is evenly spaced with impact grooves 5054. Between the active motor 501 and the stirring main shaft 506, A reducer 502 and a coupling 503 are provided, and a hollow bracket 504 is provided between the bottom surface of the reducer 502 and the top cover body 4031. The top cover assembly 403 includes a top cover body 4031 that is in contact with the top of the tank shell 401. A feeding pipe port 4032 is provided at the lateral position of the top surface of the top cover body 4031, and a main feeding port 4033 is provided on the other side of the top surface of the top cover body 4031.

[0030] On the basis of the technical solution of this embodiment, the specific working form is as follows: first, an external temperature control device is connected, including but not limited to existing products such as boilers, condensers, and constant temperature equipment, and the heat pipe between the tank shell 401 and the inner tank body 404 is connected, and the temperature control device is started to adjust the temperature inside the tank body. Then, the main material is added through the main feeding port 4033 and filled in the form of pouring into the pipeline. Then, other tanks with added materials, including additives, auxiliary materials, etc., are connected to different feeding pipe ports 4032 through flanges, and then the external pipeline can directly pump different auxiliary materials into the inner tank body 404 through a pump. According to the different addition amounts, feeding pipe ports 4032 of different calibers can be selected.
