Description

Technical Field

[0001] The invention relates to the technical field of screw conveying equipment, in particular to a screw conveyor for perchloric acid production. Background Art

[0002] Perchloric acid is an important inorganic strong acid with a wide range of industrial applications. It is often used as an analytical reagent, oxidant, catalyst, and a key raw material in certain chemical synthesis processes. The production of perchloric acid involves a variety of complex chemical reactions and material transportation processes, of which material transportation is crucial to ensuring efficient and stable production.

[0003] In traditional perchloric acid production equipment, screw conveyors are often used to transport reaction materials. However, during actual operation, due to the heat released during the reaction, the outer wall of the screw conveyor device comes into contact with the air, forming water droplets on the wall. The distribution of the water droplets is uneven, resulting in large temperature differences between different parts and causing uneven internal temperature. For example, in the outer wall area with more water droplets, heat will dissipate more slowly, causing the temperature in this area to rise faster; while in the outer wall area with fewer water droplets, heat dissipation is relatively fast, and the internal temperature is discharged faster. This difference and unevenness between internal temperatures can have a serious impact on the reaction rate in the perchloric acid production process. Because the chemical reaction rate is closely related to temperature, uneven temperature will cause inconsistent reaction rates in different parts, which in turn affects the stability and efficiency of the entire reaction process. It may cause problems such as excessive local reactions or incomplete reactions, thereby reducing the production efficiency and product quality of perchloric acid.

[0004] At the same time, traditional screw conveyors have limitations in stirring and conveying. Their stirring angle is usually fixed and cannot be adjusted according to the reaction rate requirements at different stages of the perchloric acid production process. At different stages of perchloric acid production, the reaction rate will also be different due to changes in reactant concentration, temperature and other conditions. For example, in the early stage of the reaction, the reactant concentration is high, and relatively gentle stirring is required to promote sufficient mixing of the reactants to avoid excessive reaction. In the later stage of the reaction, in order to improve the conversion rate of the reaction, it may be necessary to increase the stirring force and speed up the reaction rate. However, due to the fixed stirring angle, traditional screw conveyors are difficult to adapt to the requirements of different reaction rates and cannot flexibly stir the inside of the conveying device, thereby limiting the optimization and regulation of the entire production process.

[0005] Therefore, the present invention provides a screw conveyor for perchloric acid production to solve the above problems. Summary of the Invention

[0006] In response to the above situation and to overcome the shortcomings of the prior art, the present invention provides a screw conveyor for perchloric acid production to solve the aforementioned problem of ensuring uniform internal temperature, avoiding inconsistent reaction rates in different parts, and affecting the stability and efficiency of the entire reaction process.

When resetting, because the adjusting gear 315 is connected by a one-way bearing, it will not drive the driving shaft 314 to reset and rotate in the opposite direction. In the initial state, the angles of the blocking disk 318 inside the liquid capsule 1 311 and the liquid capsule 2 312 of the device are not the same. When the driving shaft 314 rotates half an angle, the guide hole 319 on the outer wall of the liquid capsule 1 311 is in a relative state with the connecting hole 313, the multi-stage telescopic tube 4 and the liquid capsule 1 311 are in a state of fluid conduction, and the liquid capsule 2 The guide holes 319 and the connecting holes 313 on the outer wall of the sealing disk 318 inside 312 are in a sealed state, realizing a one-in-one blocked state; the device has multiple multi-stage telescopic tubes 4, and the multiple multi-stage telescopic tubes 4 are staggered and evenly arranged, which can ensure that when the device is in use, the multi-stage telescopic tubes 4 dissipate heat evenly, and at the same time, when the sliding plate 2 is displaced, it can automatically realize multi-stage heat dissipation, and the liquid capsule for heat dissipation can be automatically replaced during heat dissipation, so that the two liquid capsules are used alternately, avoiding the phenomenon that the temperature cannot be dissipated due to the use of one liquid capsule, ensuring that the temperature of the heat dissipation liquid is reduced, so that the heat dissipation and the sliding plate 2 form a linkage function, avoiding energy waste, and realizing automatic heat dissipation.

[0045] As attached Figure 11As shown, one end of the adjusting shaft 9 is located outside the delivery pipe 1, and an adjusting bevel gear 901 is fixedly installed on the outer wall of the other end of the adjusting shaft 9; a stirring hole 801 is opened on the outer wall of the stirring blade 8, and the number of the stirring holes 801 is multiple. A stirring shaft 802 is installed at the bottom of the stirring blade 8, and a sealing member 601 is fixedly installed on the inner wall of the middle part of the spiral shaft 6. A sealing shaft 602 is installed inside the sealing member 601, and the stirring shaft 802 is connected to the inside of the spiral shaft 6 through the sealing shaft 602. The outer wall of the stirring shaft 802 at one end of the spiral shaft 6 is equipped with a rotating bevel gear 803, and the rotating bevel gear 803 is meshed with the adjusting bevel gear 901. The multiple stirring blades 8 are connected by a second transmission belt 804; in order to meet the stirring requirements of the reaction rates at various stages, the present device can achieve stirring of different intensities. When the stirring intensity needs to be adjusted, the adjusting shaft 9 is rotated to make the adjusting bevel gear 901 drive the stirring shaft 802 to rotate, thereby adjusting the angles of different stirring blades 8. In order to change the stirring intensity, it can be adjusted according to independent needs to meet the stirring of different reaction rates, making the device more applicable and more flexible. The sealing shaft 602 of the device can make the stirring shaft 802 sealed and rotatably connected to the inside of the spiral shaft 6. At the same time, the sealing shaft 602 of the device is made of a material with high corrosion resistance, such as a ceramic sealing shaft or a stainless steel sealing shaft, which can ensure the rotation adjustment of the stirring shaft 802 of the device and achieve a sealing effect, thereby avoiding the phenomenon of perchloric acid corroding the second transmission belt 804 and avoiding the phenomenon of perchloric acid entering the inside of the spiral shaft 6 and causing waste.

A discharge box 12 is installed on the bottom of the rear end of the conveying pipe 1; the feed box 11 of this device is located at the rear end of the limiting fixing ring 502, which can avoid the phenomenon that when the feed box 11 is continuously feeding, the material is located at the other end of the check plate 505 after the check plate 505 is pressurized, thereby preventing the waste of material. At the same time, when pressurized, the material is discharged from the feed box 11.
