DETAILED DESCRIPTION
[0031] In order to make the technical scheme in the present application better understood by those skilled in the art, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.
[0032] As shown in Figures 1 to 3 An embodiment of the present application is a reaction kettle for preparing chemical bulk drug, which comprises a kettle body 1, and a supporting leg 11 welded on the kettle body 1. A discharge pipe 12 connected with the inside of the kettle body 1 is installed below the kettle body 1, and a valve is installed on the discharge pipe 12. Specifically, after the chemical bulk drug in the kettle body 1 is reacted, a material receiving device is placed below the discharge pipe 12, and the valve on the discharge pipe 12 is opened, so that the chemical bulk drug in the kettle body 1 can be discharged into the material receiving device from the discharge pipe 12.
[0033] In order to prevent the chemical bulk drug from being stacked directly below the discharge pipe 12, a distribution disc 2 is further installed on the kettle body 1, the distribution disc 2 is conical, the tip of the distribution disc 2 matches the center of the discharge pipe 12, and a plurality of leakage openings 21 are formed on the distribution disc 2. The chemical bulk drug discharged from the discharge pipe 12 is diffused and distributed by the distribution disc 2 and the leakage openings 21, so that the area occupied by the chemical bulk drug when falling can be increased. To some extent, the chemical bulk drug can be prevented from being stacked in a conical shape below the discharge pipe 12.
[0034] Meanwhile, an adjusting assembly is installed on the kettle body 1, and the distribution disc 2 is installed on the adjusting assembly, and the adjusting assembly is used to adjust the distance between the distribution disc 2 and the discharge pipe 12. In this way, the direction of the chemical bulk drug diffused and distributed by the distribution disc 2 and the leakage openings 21 can be changed, so that the chemical bulk drug discharged from the kettle body 1 can be evenly dropped into the material receiving device.
[0035] As shown in Figure 1 Figure 3 and Figure 4 The adjusting assembly comprises a first fixed column 3 welded on the kettle body 1, a first sliding groove 31 is formed on the first fixed column 3, a first sliding column 33 is slidably connected in the first sliding groove 31, a connecting rod 37 is installed on the end face of the first sliding column 33 away from the first sliding groove 31, and the end of the connecting rod 37 away from the first sliding column 33 is welded on the distribution disc 2.
[0036] Specifically, the distance between the distribution disc 2 and the discharge pipe 12 can be changed by sliding the first sliding column 33 in the first fixed column 3. When the discharge pipe 12 discharges, the distribution disc 2 is first adjusted to a position close to the discharge pipe 12, at which time the chemical raw materials discharged from the discharge pipe 12 will slide down from the distribution disc 2 and the discharge opening 21 to the receiving device with the largest diffusion area. Then, according to the accumulation of the chemical raw materials in the receiving device, the first sliding column 33 is slid downward, so that the chemical raw materials can be evenly dropped into the receiving device and not all accumulated directly below the discharge pipe 12.
[0037] In order to fix the height of the first sliding column 33 on the first fixed column 3, a second sliding groove 32 is formed in the first fixed column 3 and communicates with the first sliding groove 31. A plurality of clamping grooves 321 are formed in the groove wall of the second sliding groove 32, and a first supporting rod 35 matched with the clamping grooves 321 is slidably connected to the first sliding column 33.
[0038] Specifically, a third sliding groove 331 is formed in the first sliding column 33, the third sliding groove 331 is parallel to the clamping grooves 321, a sliding block 34 is slidably connected in the third sliding groove 331, and the first supporting rod 35 is integrally formed on the sliding block 34. By sliding the first sliding column 33, the first supporting rod 35 is aligned with the clamping grooves 321 of the desired height, then the first supporting rod 35 is pushed, and the sliding block 34 will slide horizontally in the third sliding groove 331, so that the first supporting rod 35 is clamped into the clamping grooves 321, and the first sliding column 33 is fixed.
[0039] Further, the first supporting rod 35 is wrapped with a first rubber layer 351. The elasticity of the first rubber layer 351 can firmly clamp the first supporting rod 35 in the clamping grooves 321, preventing the impact of the chemical raw materials on the distribution disc 2 from causing the distribution disc 2 to vibrate and causing the first supporting rod 35 to fall out of the clamping grooves 321.
[0040] It is worth noting that although the distribution disc 2 can distribute the chemical raw materials, the tip of the distribution disc 2 cannot leak, resulting in a certain area of blank directly below the distribution disc 2, affecting the loading capacity of the receiving device.
[0041] As shown in Figure 3 , Figure 5 and Figure 6 , a thrust ball bearing 36 is provided between the first sliding column 33 and the connecting rod 37, and a second supporting rod 38 is integrally formed on the thrust ball bearing 36. Pushing the second supporting rod 38 can make the connecting rod 37 rotate on the first sliding column 33 through the thrust ball bearing 36, so that the distribution disc 2 is away from the direct below of the discharge pipe 12, and the chemical raw materials can directly fall into the receiving device from the discharge pipe 12, so that the chemical raw materials in this part of the receiving device are flush with other positions, and the loading capacity of the receiving device is ensured.
[0042] Further, the kettle body 1 is welded with a second fixing column 4, a second sliding column 41 is slidably connected in the second fixing column 4, and a supporting plate 42 is integrally formed on the second sliding column 41. The supporting plate 42 is matched with a supporting groove 22 formed on the distribution disc 2. Specifically, when the distribution disc 2 is directly below the discharge pipe 12, the supporting plate 42 is clamped in the supporting groove 22, the supporting plate 42 supports the distribution disc 2 away from one side of the connecting rod 37, and the distribution disc 2 is prevented from being skewed.
[0043] In addition, the supporting plate 42 is wrapped with a second rubber layer 421. When the supporting plate 42 is clamped in the supporting groove 22, the friction between the second rubber layer 421 and the groove wall of the supporting groove 22 can make the distribution disc 2 more stable, and prevent the distribution disc 2 from rotating after being stressed.
[0044] Further, the opening direction of the leakage port 21 is inclined to the horizontal plane, and the opening directions of the leakage ports 21 of the plurality of groups are different, so that the material distribution capacity of the distribution disc 2 is improved, and the chemical raw materials falling into the material receiving device are more uniform.
[0045] In use, the valve on the discharge pipe 12 is opened, the chemical raw materials are discharged from the discharge pipe 12 to the distribution disc 2, the distribution disc 2 distributes the chemical raw materials, and the area of the chemical raw materials falling is expanded. By adjusting the distance between the distribution disc 2 and the discharge pipe 12, the area of the chemical raw materials falling can be changed, the chemical raw materials are prevented from being accumulated in a cone shape in the material receiving device, and by moving the distribution disc 2 below the discharge pipe 12, the chemical raw materials can also be discharged at the position directly below the distribution disc 2, so that the loading capacity of the material receiving device is ensured.
[0046] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced therein. Any reference signs in the claims should not be considered as limiting the claims to which they relate.
[0047] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
