Description

Technical Field

[0003] A search revealed CN217403876U, which discloses an anti-adhesion vacuum reactor sampling device. The device includes a reactor body with a sampling device located on its right side. An upper conveying device and a lower conveying device are respectively located on the upper and lower sides of the sampling device. This invention uses two conveying pipes, one and two, connected to the upper and lower sides of the sampling pipe. When valves two and three on conveying pipe one are opened, and valves four and five on conveying pipe two are opened, the liquid material in the reactor body can enter the sampling pipe. Then, valves two, three, four, and five are closed, and valve one on the connecting pipe is closed. By rotating connecting sleeves one and two, the device can detach from the two connecting pipes, allowing the sampling pipe to be directly removed, thus preventing the sampled liquid from being exposed.

[0004] However, the material inside the reactor sometimes separates into layers, and existing devices are not convenient for sampling materials at different heights. Therefore, we need a sampling device for vacuum reactors that can sample materials at different heights. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a sampling device for a vacuum reactor, which has the following beneficial effects:

[0015] 1. The sampling device of this vacuum reactor, by setting up a discharge pipe, a sampling box, and a sampling barrel, allows for adjustment of the sampling barrel's height by raising and lowering it. When the sampling barrel is moved to the desired sampling height, the second magnet attracts the first magnet, causing the push-pull rod and piston to move to the right, thereby drawing material from the suction pipe into the sampling barrel. Then, the sampling barrel is moved to its highest position, aligning the suction pipe with the discharge pipe, and the second magnet repels the first magnet, causing the piston to move to the left, thus squeezing the material in the sampling barrel into the sample collection mechanism. By disassembling the sample collection mechanism, the collected material can be easily tested. This invention can sample materials at different heights, thus providing convenience for users.

[0016] 2. The sampling device of this vacuum reactor can block the suction pipe by setting a solenoid valve, thereby effectively avoiding the mixing and contamination of the material in the sampling box with the material in the sampling bucket during the up and down movement of the sampling bucket.

[0017] 3. The sampling device of the vacuum reactor, by setting a first manual valve and a second manual valve, allows the material in the sampling bucket to enter the collection box through the connecting pipe and the discharge pipe when the first manual valve and the second manual valve are opened. When the first manual valve and the second manual valve are closed, it can effectively prevent external dust from entering the sampling box through the discharge pipe after the sample collection mechanism is disassembled, thereby ensuring that the material in the sampling box is not contaminated by external dust.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a technical solution: a sampling device for a vacuum reactor, including a reactor body 1, a sampling mechanism 2 arranged on the side of the reactor body 1, the sampling mechanism 2 including multiple discharge pipes 3 and a sampling box 4, one end of the multiple discharge pipes 3 being fixedly connected to the side of the sampling box 4, and the other end of the multiple discharge pipes 3 being fixedly connected to the side of the reactor body 1, a sampling barrel 5 that can be raised and lowered is arranged inside the sampling box 4, a suction pipe 6 is arranged on the left side of the sampling barrel 5, a piston 7 is slidably connected to the inner wall of the sampling barrel 5, a push-pull rod 8 is fixedly connected to the surface of the piston 7, a first magnet 9 is fixedly connected to the end of the push-pull rod 8, a discharge pipe 10 is fixedly connected to the upper left side of the sampling box 4, a sample collection mechanism 11 is detachably installed at the end of the discharge pipe 10, and a storage box 12 is fixedly connected to the rear side of the sampling box 4, and the storage box 12 contains... Equipped with a second magnet 13, and with a discharge pipe 3, sampling box 4, and sampling barrel 5, the height of the sampling barrel 5 can be adjusted by raising and lowering it. When the sampling barrel 5 is moved to the required sampling height, the second magnet 13 attracts the first magnet 9, which drives the push-pull rod 8 and piston 7 to move to the right, thereby sucking the material from the suction pipe 6 into the sampling barrel 5. Then, the sampling barrel 5 is moved to its highest position, and the suction pipe 6 is aligned with the discharge pipe 10. The second magnet 13 then repels the first magnet 9, which drives the piston 7 to move to the left, thereby squeezing the material in the sampling barrel 5 into the sample collection mechanism 11. By disassembling the sample collection mechanism 11, the collected material can be easily tested. This utility model can sample materials at different heights, thus providing convenience for users.

[0026] The number of discharge pipes 3 is at least ten, and the height difference between two adjacent discharge pipes 3 is equal. By setting multiple discharge pipes 3, it is convenient for materials of different heights in the reactor body 1 to enter the sampling box 4.

[0027] A solenoid valve 14 is installed on the suction pipe 6. By installing the solenoid valve 14, the suction pipe 6 can be blocked, thereby effectively preventing the material in the sampling box 4 from mixing and contaminating the material in the sampling bucket 5 during the up and down movement of the sampling bucket 5.

[0028] The sample collection mechanism 11 includes a collection box 15 and a connecting pipe 16. The connecting pipe 16 is threaded to the outside of the discharge pipe 10, and the collection box 15 is fixedly connected to the left side of the connecting pipe 16. The connecting pipe 16 and the discharge pipe 10 are threaded together to allow for the disassembly and installation of the collection box 15.

[0029] A first manual valve 17 is provided on the connecting pipe 16, and a second manual valve 18 is provided on the discharge pipe 10. By setting the first manual valve 17 and the second manual valve 18, opening the first manual valve 17 and the second manual valve 18 can facilitate the material in the sampling bucket 5 to enter the collection box 15 through the connecting pipe 16 and the discharge pipe 10. Closing the first manual valve 17 and the second manual valve 18 can effectively prevent external dust from entering the sampling box 4 through the discharge pipe 10 after the sample collection mechanism 11 is disassembled, thereby ensuring that the material in the sampling box 4 is not contaminated by external dust.

[0030] A first connecting rod 19 is fixedly connected to the upper surface of the sampling barrel 5, and the first connecting rod 19 extends to the outside of the sampling box 4. An end block 20 is fixedly connected to the upper end of the first connecting rod 19. A height adjustment mechanism for controlling the up and down movement of the end block 20 is provided on the surface of the sampling box 4. The height adjustment mechanism includes a servo motor 21, an adjusting screw 22, a movable plate 23, a second connecting rod 24, a first side plate 25, and a second side plate 26. The first side plate 25 and the second side plate 26 are both fixedly connected to the surface of the sampling box 4. The adjusting screw 22 is rotatably connected between the first side plate 25 and the second side plate 26. The movable plate 23 is threadedly connected to the outside of the adjusting screw 22 and is slidably connected to the surface of the sampling box 4. The servo motor 21 is fixedly connected to the lower surface of the second side plate 26, and the output end of the servo motor 21 is drively connected to the adjusting screw 22. The second connecting rod 24 is fixedly connected between the movable plate 23 and the end block 20.

[0031] Working principle: When the sampling device of the vacuum reactor is sampling, the servo motor 21 is first turned on. The servo motor 21 drives the adjusting screw 22 to rotate, which in turn moves the movable plate 23 upward. The upward movement of the movable plate 23 drives the second connecting rod 24 and the end block 20 upward, which in turn moves the first connecting rod 19 and the sampling barrel 5 upward. When the sampling barrel 5 reaches the target height, the solenoid valve 14 is turned on. The second magnet 13 attracts the first magnet 9, which drives the push-pull rod 8 and the piston 7 to move to the right, so that the material can be sucked into the sampling barrel 5 from the suction pipe 6. Then, the sampling barrel 5 is moved to the highest position, and the suction pipe 6 is aligned with the discharge pipe 10. The second magnet 13 then repels the first magnet 9, which drives the piston 7 to move to the left, so that the material in the sampling barrel 5 can be squeezed into the sample collection mechanism 11. By disassembling the sample collection mechanism 11, the collected material can be easily tested. This utility model can sample materials at different heights, thus providing convenience for users.
