Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a pressure tank device for producing lopinavir. Background Technology

[0002] With large-scale industrial production, the demand for chemical products is increasing. Generally, chemical raw materials need to be mixed and stirred before being fed into chemical production lines for processing.

[0003] In existing technologies, chemical raw materials are generally mixed in a reaction vessel, and after mixing, they are injected into a pressure tank, and then output from the pressure tank to the chemical production line for production.

[0004] However, when the mixture is put into the pressure vessel, it is easy for lumps to form, which affects the reaction of the mixture.

[0005] Therefore, it is necessary to propose a pressure tank that can prevent agglomeration when the mixture is added. Utility Model Content

[0006] The purpose of this invention is to provide a pressure tank device for producing lopinavir, so as to at least partially solve the above-mentioned technical problems and prevent the mixture from agglomerating when it is put into the pressure tank.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a tank, an injection unit, and a crushing unit, wherein the tank is a pressure tank configured for the reaction of the mixture, and the injection unit and the crushing unit are both installed on the top of the tank;

[0008] The injection unit includes a conduit disposed on the top of the tank and inserted into the tank. The top of the conduit is provided with a circular connecting block. The top of the connecting block is connected to a fixing block by bolts. Both the top of the fixing block and the connecting block are provided with through holes.

[0009] The crushing unit includes a feeding cylinder installed on the top of the fixed block. The feeding cylinder has an inlet inside. The lower surface of the inlet is connected to the guide tube through the feeding cylinder and has a drop hole. A support mechanism is fixedly installed on the top of the feeding cylinder. A drive motor is fixedly installed on the top of the support mechanism. A rotating shaft is rotatably installed on the bottom of the drive motor. A crushing mesh is threadedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the conduit and the drop hole are in the same vertical plane.

[0011] Preferably, the connecting block is fitted to the fixing block, and the bolt is passed through the connecting block and the fixing block through the through hole.

[0012] Preferably, the feeding cylinder is arranged in a fan-shaped cylindrical form, and the upper surface area of ​​the feeding cylinder is larger than the lower surface area.

[0013] Preferably, the rotating shaft and the drop hole are on the same vertical plane, and the rotating shaft does not contact the inner wall of the feed inlet.

[0014] Preferably, the crushing mesh is arranged in a fan-shaped cylindrical shape, and the crushing mesh does not contact the inner wall of the feed inlet.

[0015] Preferably, the crushing mesh is arranged in a mesh pattern.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In use, the mixture is injected into the feeding cylinder through the inlet. The drive motor drives the rotating shaft and the crushing screen to rotate. The mixture falls onto the crushing screen and is broken up and separated. The rotation of the crushing screen can further break up the mixture, so that the mixture falls downward in a dispersed form and falls through the drop hole into the guide tube and enters the tank. This effectively prevents the mixture from clumping during feeding, disperses the mixture more fully, and reduces the impact on subsequent reactions. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a pressure vessel device for producing lopinavir, comprising a vessel body 100, an injection unit 200 and a crushing unit 300. The vessel body 100 is a pressure vessel set for the reaction of the mixture. The injection unit 200 and the crushing unit 300 are both installed on the top of the vessel body 100.

[0028] Tank 100 is a conventional pressure tank used for reaction and has no other special purpose, so it will not be described in detail here. The injection unit 200 and the crushing unit 300 are located on the top of tank 100 for convenient feeding operations.

[0029] See Figure 1 and Figure 3 In a preferred embodiment, the injection unit 200 includes a conduit 210 disposed on the top of the tank 100 and inserted into the tank 100.

[0030] The conduit 210 facilitates the downward flow of the mixture injected from the top of the crushing unit 300 into the tank 100, serving as a guide.

[0031] The top of the conduit 210 is provided with a circular connecting block 220. The top of the connecting block 220 is connected to a fixing block 230 by bolts. Both the top of the fixing block 230 and the connecting block 220 are provided with through holes 231. The connecting block 220 fits into the fixing block 230. Bolts are passed through the connecting block 220 and the fixing block 230 through the through holes 231.

[0032] The connecting block 220 and the fixing block 230 can be fitted together, so that the injection unit 200 and the crushing unit 300 can be initially connected together. Then, the connecting block 220 and the fixing block 230 are tightly connected together by bolts, so that the crushing unit 300 is stably connected to the tank 100 through the injection unit 200, preventing the crushing unit 300 from tipping over or other situations.

[0033] See Figure 1 and Figure 2In a further preferred embodiment, the crushing unit 300 includes a feeding cylinder 310 mounted on the top of the fixed block 230. The feeding cylinder 310 has an inlet 311 inside. The feeding cylinder 310 is arranged in a fan-shaped cylindrical shape. The feeding cylinder 310 has an upper surface area larger than its lower surface area. The lower surface inside the inlet 311 passes through the feeding cylinder 310 and is connected to the guide tube 210 to form a drop hole 3111. The guide tube 210 and the drop hole 3111 are on the same vertical plane.

[0034] The feed inlet 311 allows for easier feeding of more mixed material into the feeding cylinder 310, where it is continuously acted upon by the crushing unit 300 to prevent clumping and ensure continuous action on the mixed material in the feeding cylinder 310. The drop hole 3111 ensures that the mixed material falls directly into the tank 100 through the conduit 210, maintaining stable conveying of the mixed material.

[0035] See Figure 1-3 In a further preferred embodiment, a support mechanism 320 is fixedly installed on the top of the feeding cylinder 310, a drive motor 330 is fixedly installed on the top of the support mechanism 320, and a rotating shaft 331 is rotatably installed on the bottom of the drive motor 330. The rotating shaft 331 and the drop hole 3111 are on the same vertical plane, and the rotating shaft 331 does not contact the inner wall of the feed inlet 311.

[0036] The mounting mechanism 320 enables the drive motor 330 to be stably installed and used, driving the rotating shaft 331 and the crushing screen 340 to rotate. The rotating shaft 331 will not cause the mixture to accumulate. The rotating shaft 331 can drive the mixture to rotate to a certain extent to keep the drop hole 3111 unobstructed and prevent blockage. The rotating shaft 331 will not rub against the inner wall of the feed inlet 311 and cause wear.

[0037] The outer wall of the rotating shaft 331 is threaded with a crushing mesh 340. The crushing mesh 340 is arranged in a fan-shaped cylindrical shape. The crushing mesh 340 does not contact the inner wall of the feed inlet 311 and is arranged in a mesh pattern.

[0038] When the mixture falls onto the crushing mesh 340, it is immediately crushed and dispersed by the mesh. As the crushing mesh 340 rotates further, it can further crush and disperse the mixture, further preventing the mixture from clumping. The crushing mesh 340 will not come into contact with the inner wall of the feed inlet 311 and will not experience wear. The fact that the crushing mesh 340 does not come into contact with the inner wall of the feed inlet 311 can maintain a gap, preventing the accumulation of the mixture. Furthermore, the centrifugal force of the crushing mesh 340 can throw the mixture off its surface and allow it to slide down the inclined surface of the inner wall of the feed inlet 311.
