Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, and in particular to a material feeding mechanism for a vacuum reactor. Background Technology

[0002] In the preparation of theanine, the dilute theanine solution needs to be evaporated and concentrated in a vacuum reactor. To ensure the airtightness of the vacuum reactor, the safest approach is to feed the material under a vacuum inside the reactor. In the existing technology, because the inside of the vacuum reactor is under negative pressure, the feed rate is uneven during feeding due to the negative pressure, which affects the stability of the feeding process. At the same time, external gases may enter the reactor body during feeding, affecting the airtightness. Utility Model Content

[0003] This invention provides a feeding mechanism for a vacuum vessel to solve the problems mentioned in the background art.

[0004] In view of this, the present invention aims to provide a feeding mechanism for a vacuum vessel. In the present invention, the feeding mechanism is provided on the vacuum vessel and includes a feed hopper, a shell and a discharge hopper connected in sequence, wherein the discharge hopper is located inside the vacuum vessel.

[0005] The housing is equipped with a metering component, which includes a feeding tray and a drive motor. The output shaft of the drive motor passes through the interior of the housing, is connected to the feeding tray, and drives the feeding tray to rotate.

[0006] The feeding tray has several feeding chambers evenly arranged circumferentially. When the feeding chamber rotates to the top, it is connected to the feeding hopper. When the feeding chamber rotates to the bottom, it is connected to the discharging hopper.

[0007] By setting up a quantitative component, the material entering from the feed hopper is quantitatively fed by each feeding chamber. As the feeding disc rotates, the material is fed, ensuring that the amount of material entering the vacuum vessel body each time is the same, thus guaranteeing the stability of the feeding.

[0008] Furthermore, the housing includes an outer shell and an inner shell, the feeding tray is disposed inside the inner shell, and a negative pressure channel is formed between the outer shell and the inner shell;

[0009] The outer casing is provided with a negative pressure connector for connection to a negative pressure device, the negative pressure channel is connected to the negative pressure connector, and the negative pressure channel is connected to the discharge hopper.

[0010] By combining the negative pressure channel with the housing of the feeding mechanism, the inside of the housing can be evacuated simultaneously when negative pressure is drawn, and the airtightness of the feeding mechanism can be tested at the same time.

[0011] Furthermore, an opening and closing component is provided at one end of the feed hopper near the housing. The opening and closing component is used to control the opening and closing of the feed hopper. When liquid is injected into the feed hopper, the opening and closing component automatically opens, thereby automating the opening and closing of the component during feeding.

[0012] Furthermore, the opening and closing assembly includes a sealing plate, a buoyancy ball, a first toothed rod, a second toothed rod, a first transmission wheel, and a second transmission wheel; the sealing plate opens and closes the discharge port of the feed hopper;

[0013] One end of the sealing plate is connected to the first toothed rod, which meshes with the first transmission wheel. The first transmission wheel and the second transmission wheel are coaxially arranged. The second toothed rod is meshed with one side of the second transmission wheel. The buoyancy ball is connected to the top of the second toothed rod and is located inside the feed hopper. When material is fed, the buoyancy ball is lifted by the feeding of the material, thereby causing the sealing plate to open automatically.

[0014] Furthermore, a tension spring is provided at the bottom of the second rack to drive the second rack to reset.

[0015] The present invention discloses a feeding mechanism for a vacuum vessel. By setting a quantitative component, the material entering the feed hopper is quantitatively fed by each feeding chamber, so that the amount of material entering the vacuum vessel each time is the same, ensuring the stability of feeding. At the same time, the airtightness of the feeding mechanism can be detected during vacuuming, and the inside of the feeding mechanism can be evacuated.

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In the preparation of theanine, the dilute theanine solution needs to be evaporated and concentrated in a vacuum reactor. To ensure the airtightness of the vacuum reactor, the safest approach is to feed the material under a vacuum inside the reactor. In the existing technology, because the inside of the vacuum reactor is under negative pressure, the feed rate is uneven during feeding due to the negative pressure, which affects the stability of the feeding process. At the same time, external gases may enter the reactor body during feeding, affecting the airtightness.

[0028] This utility model provides a feeding mechanism for a vacuum reactor, such as... Figure 1 As shown, in this embodiment, the feeding mechanism is located on the vacuum vessel body. The feeding mechanism includes a feed hopper 100, a shell 200, and a discharge hopper 300 connected in sequence. The discharge hopper 300 is located inside the vacuum vessel body, and the feed hopper 100 is located outside the vacuum vessel body. The material enters from the feed hopper 100, passes through the shell 200, and enters the discharge hopper 300. The material then enters the interior of the vessel body from the discharge hopper 300.

[0029] like Figure 2 As shown, a metering component is installed inside the housing 200. The metering component includes a feeding tray 230 and a drive motor. The drive motor is mounted on the vacuum vessel body, and its output shaft passes through the interior of the housing 200 and connects to the feeding tray 230. The drive motor drives the feeding tray 230 to rotate inside the housing 200. Several feeding chambers 231 are evenly arranged circumferentially on the feeding tray 230. Each feeding chamber 231 is the same size to ensure that the feeding amount is consistent when feeding into each feeding chamber 231. The top and bottom of the housing 200 are open so that the feeding chambers 231 can connect with the feed hopper 100 and the discharge hopper 30. When the feeding chamber 231 is in any other position, it is sealed. When the feeding chamber 231 rotates to the top, it is connected to the feeding hopper 100. When the feeding chamber 231 rotates to the bottom, it is connected to the discharging hopper 300. The drive motor drives the feeding disc 230 to rotate for feeding. When the feeding disc 231 rotates to the top, each feeding chamber 231 is connected to the feeding hopper 100 in sequence. Liquid is fed into each feeding chamber 231 in sequence from the feeding hopper 100. When the feeding disc 231 rotates to the bottom, each feeding chamber 231 discharges material into the discharging hopper 300. This ensures that each feeding chamber 231 feeds material in sequence and that the feeding amount is stable.

[0030] To ensure stable material supply and prevent residual gases from entering the reactor body, the shell 200 is configured as an outer shell 210 and an inner shell 220, spaced apart. The feeding tray 230 is located inside the inner shell 220 and can rotate within it. A negative pressure channel 240 is formed between the outer shell 210 and the inner shell 220. A negative pressure connector 250 connected to a negative pressure device is provided on the outer shell 210. The negative pressure channel 240 is connected to the negative pressure connector 250 and communicates with the discharge hopper 300. When drawing negative pressure, the interior of the shell 200 is simultaneously evacuated, and the airtightness of the feeding mechanism is checked. In addition, during vacuuming, the feeding tray 230 is rotated to evacuate the interior of each feeding chamber 231, ensuring stable material feeding.

[0031] To ensure the sealing of the feed; such as Figure 2As shown, an opening and closing component 400 is provided at one end of the feed hopper 100 near the housing 200. The opening and closing component 400 is used to control the opening and closing of the feed hopper 100. When liquid is injected into the feed hopper 100, the opening and closing component 400 automatically opens, realizing the automation of the opening and closing component 400 during feeding.

[0032] like Figure 3 and Figure 4 As shown, the opening and closing assembly 400 is configured as a sealing plate 410, a buoyancy ball 420, a first toothed rod 430, a second toothed rod 440, a first transmission wheel 450, and a second transmission wheel 460. The sealing plate 410 can open and close the outlet of the feed hopper 100. One end of the sealing plate 410 is connected to the first toothed rod 430, and the sealing plate 410 and the first toothed rod 430 are horizontally arranged. The first toothed rod 430 meshes with the first transmission wheel 450, and the first transmission wheel 450 and the second transmission wheel 460 are coaxially arranged and rotatably installed in the feed hopper 100 through a rotating shaft. The second toothed rod 440 is meshed with one side of the second transmission wheel 460. The second toothed rod 440 is vertically arranged, and the top of the second toothed rod 440 is connected to the buoyancy ball 420, which can drive the second toothed rod 440 to move upward. The buoyancy ball 420 is located inside the feed hopper 100. When the material is fed, as the original liquid material continues to flow... As the liquid level in the feed hopper 100 increases, the buoyancy ball 420 floats upward. This upward movement of the buoyancy ball 420 drives the second gear 440 upward, which in turn drives the second transmission wheel 460 to rotate. The first transmission wheel 450 rotates synchronously, causing the first gear 430 to move. The first gear 430 and the sealing plate 410 move, opening the outlet of the feed hopper 100, allowing the material in the feed hopper 100 to enter the feeding chamber 231. This achieves automatic feeding into the feeding chamber 231 during feeding. The outlet only opens when the liquid level reaches a certain height (at least higher than the buoyancy ball 420 and the buoyancy is greater than the tension of the tension spring 470), ensuring a water seal inside the feed hopper 100 before feeding into the feeding chamber 231. This prevents external gas from entering the feeding chamber 231, further improving the stability of feeding into the vacuum vessel.

[0033] A tension spring 470 is provided at the bottom of the second toothed rod 440. When no material is being fed into the feed hopper 100 or when the liquid level is low, the tension spring 470 is used to drive the second toothed rod 440 to reset and tighten the discharge port of the feed hopper 100 to avoid affecting the airtightness.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
