Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure reactors, in particular to a stainless steel high-pressure reactor for purifying antimony trioxide. Background Art

[0002] Antimony trioxide is an inorganic compound. Its natural product is called antimony flower, commonly known as antimony white. It is a white crystalline powder, soluble in concentrated hydrochloric acid, sulfuric acid, alkaline solution and hot tartaric acid solution, slightly soluble in water, dilute nitric acid and dilute sulfuric acid. It is mainly used as a pigment, flame retardant, mordant, catalyst, and can also be used to synthesize antimony salts. During its production and processing, a special high-pressure reactor is required for purification.

[0003] When purifying antimony trioxide in an existing high-pressure reactor, the raw materials are mainly placed in the reactor, and the raw materials are continuously heated by the equipment to remove the moisture in the raw materials to achieve the purification of antimony trioxide. However, there are still certain deficiencies in the actual working process. The top cover of the existing high-pressure reactor is mostly a flip-type structure. After the purification work is completed, affected by the residual temperature in the reactor, it is easy for the product solution to adhere to the inner side of the cover. When the cover is flipped open, the product liquid drips on the outside of the device, causing waste of the product. Moreover, simply relying on the heating device to heat the raw materials in the container cannot make the solution at each position in the container heated evenly, and the purification effect is not good. For this reason, we designed a stainless steel high-pressure reactor for purifying antimony trioxide to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a stainless steel high-pressure reactor for purifying antimony trioxide, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a stainless steel high-pressure reactor for purifying antimony trioxide, comprising a controller and a reaction vessel, the reaction vessel is fixedly mounted above the controller, and a heating module is mounted on the outside of the reaction vessel, two groups of symmetrically distributed electric telescopic rods are fixedly mounted on the controller, the top ends of the driving rods of the electric telescopic rods are mounted with support frames, a sealing cover is connected between the two groups of support frames, a servo motor is mounted on the middle part of the top end of the sealing cover, a stirring shaft is movably mounted in the controller through a bearing, the driving shaft of the servo motor extends to the bottom of the sealing cover and is fixedly mounted with a sleeve joint matching the stirring shaft, and the outside of the stirring shaft is connected to evenly distributed stirring rods.

[0006] Furthermore, a control panel is provided at the front end of the controller, and evenly distributed heat dissipation openings are provided at the outer side of the controller.

[0007] Furthermore, the top end of the sealing cover is connected to an air intake pipe and an air exhaust pipe which are symmetrically distributed, and control valves are mounted on the outer sides of the air intake pipe and the air exhaust pipe.

[0008] Furthermore, a pressure gauge is fixedly installed above the sealing cover, and the pressure gauge, the air inlet pipe, and the exhaust pipe are all interconnected with the reaction container.

[0009] Furthermore, a cross protrusion is sleeved on the top end of the stirring shaft, and a cross groove matching the cross protrusion is provided in the sleeve joint.

[0010] Furthermore, the support frame is in a Z shape, the exteriors of the reaction container and the sealing cover are both made of stainless steel, and a sealing gasket matching the inner wall of the reaction container is provided at the bottom end of the sealing cover.

[0011] Furthermore, the electric telescopic rods are symmetrically distributed on both sides of the reaction container, and the sealing cover is located directly above the reaction container.

[0012] The utility model provides a stainless steel high-pressure reactor for purifying antimony trioxide, which has the following

[0013] Beneficial effects:

[0014] 1. The stainless steel high-pressure reactor for purifying antimony trioxide uses a servo motor box sleeve joint and a stirring shaft box cross protrusion in combination, so that when the sealing cover of the stainless steel high-pressure reactor for purifying antimony trioxide closes the top of the reaction container, the sleeve joint on the servo motor drive shaft can be docked with the cross protrusion at the top of the stirring shaft, and the cross protrusion is sleeved in the cross groove on the inner side of the sleeve joint to achieve the connection between the sleeve joint and the stirring shaft. When the servo motor is working, the driving shaft can drive the stirring shaft to rotate as a whole, and then drive the stirring rod on the stirring shaft to stir the raw materials in the reaction container, so that each part of the raw material is heated evenly, thereby improving the purification effect of the stainless steel high-pressure reactor for purifying antimony trioxide.

[0015] 2. The stainless steel high-pressure reactor for purifying antimony trioxide is used in combination with an electric telescopic rod, a support frame and a sealing cover. When the reaction container of the stainless steel high-pressure reactor for purifying antimony trioxide needs to be opened, the electric telescopic rod can work and drive the support frame to move upward through its driving shaft. The sealing cover is driven to leave the top of the reaction container through two groups of support frames to release the seal of the reaction container. The sealing cover is also located directly above the reaction container in the open state. Even if there is residual product solution on the inner wall of the sealing cover, it can be directly dripped into the reaction container, thereby effectively avoiding waste of the product.
