Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a sampling device for a bromination reactor. Background Technology

[0002] A bromination reactor is a chemical equipment used for bromination reactions. It provides a specific reaction environment for the bromination reaction, allowing reactants to undergo a chemical reaction under certain conditions of temperature, pressure, and stirring to generate the target brominated product. It is typically made of materials such as stainless steel (e.g., 304, 316L) or glass-lined enameled steel. Stainless steel has good corrosion resistance and mechanical strength, making it suitable for various bromination reaction systems; glass-lined enameled steel can resist the erosion of various corrosive media such as acids, alkalis, and salts, and is especially suitable for bromination reactions that are highly corrosive to metals.

[0003] The existing reactor has a valve on one side of its outer wall for sampling;

[0004] However, the sampling valves of existing reaction vessels do not have a protective structure when in use, and the sample may splash everywhere during the sampling process using a beaker. To address this problem, a sampling device for a bromination reaction vessel is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a sampling device for a bromination reactor to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a sampling device for a bromination reactor, including a reactor, a sampling valve is provided on one side of the outer wall of the reactor, a sealing plate is fixedly sleeved on the outer wall of the sampling valve, a fixed plate is provided on one side of the outer wall of the reactor, a screw is rotatably connected to the fixed plate through a bearing, the bottom end of the screw extends to the bottom end of the fixed plate and is provided with a handle, a movable cylinder is screwed to the top end of the screw, a lifting plate is provided at the top end of the movable cylinder, a telescopic cylinder is provided at the top end of the fixed plate, a telescopic rod is slidably inserted into the inner cavity of the telescopic cylinder, and the top end of the telescopic rod is fixedly connected to the bottom end of the lifting plate.

[0006] Preferably, the inner wall of the telescopic cylinder is provided with a connecting groove, and a connecting block is slidably embedded in the inner cavity of the connecting groove. The connecting block is fixedly connected to the outer wall of the telescopic rod.

[0007] Preferably, the inner cavity of the connecting groove and the outer wall of the connecting block are adapted to each other and are both dovetail-shaped.

[0008] Preferably, the outer circumference of the handle is provided with anti-slip ridges.

[0009] Preferably, the top of the lifting plate is provided with a frame, and the left side of the inner cavity of the frame is rotatably connected to a lead screw via a bearing. The other end of the lead screw extends to the right end of the frame and is fixedly connected to a knob. The threads on the left and right sides of the outer wall of the lead screw are arranged opposite to each other and are respectively screwed to sliders. The top of the two sliders is provided with clamping plates. The two clamping plates are provided with fixing grooves on the side that is close to each other. The top of the lifting plate is provided with a bracket.

[0010] Preferably, the inner cavity of the fixing groove is inclined from the front and rear sides towards the middle.

[0011] Preferably, the top of the lifting plate is provided with a limiting groove, and two limiting blocks are slidably embedded in the inner cavity of the limiting groove. The two limiting blocks are respectively fixedly connected to the bottom ends of the two sliders. The inner cavity of the limiting groove and the outer wall of the limiting blocks are adapted to each other and are both in the shape of "T".

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Rotate the handle to drive the screw to rotate. Under the rotational force of the screw's outer thread, when the screw rotates, the moving cylinder can push the lifting plate and the beaker placed on the lifting plate to slide upward in a straight line under the limiting action of the telescopic rod and the telescopic cylinder. This allows the beaker to be fitted onto the output end of the sampling valve and to make tight contact with the bottom end of the sealing plate, thereby fixing and sealing the beaker and preventing the sample from splashing everywhere. This solves the problem that the sampling valve of the existing reactor does not have a protective structure and that the sample will splash everywhere during the sampling process using the beaker.

[0014] 2. By rotating the knob, the lead screw is rotated, which in turn generates a relative thread rotational force on the opposite threads on the left and right sides of the lead screw's outer wall. Under the limiting action of the limiting groove and the limiting block, the two sliders slide simultaneously towards the middle of the lead screw. Under the limiting action of the limiting groove and the limiting block, the two sliders respectively drive the two clamping plates to slide simultaneously towards the top center of the lifting plate. This clamps the beaker placed on the support with the fixing groove, thus preventing the beaker from falling during the up and down sliding process of the lifting plate, and improving the stability of the device during use.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a sampling device for a bromination reactor, including a reactor 1. A sampling valve 2 is provided on one side of the outer wall of the reactor 1, and a sealing plate 3 is fixedly sleeved on the outer wall of the sampling valve 2. A fixing plate 4 is provided on one side of the outer wall of the reactor 1. A screw 8 is rotatably connected to the fixing plate 4 via a bearing. The bottom end of the screw 8 extends to the bottom end of the fixing plate 4 and is provided with a handle 10. A movable cylinder 9 is screwed to the top end of the screw 8. A lifting plate 5 is provided at the top end of the movable cylinder 9. A telescopic cylinder 11 is provided at the top end of the fixing plate 4. A telescopic rod 12 is slidably inserted into the inner cavity of the telescopic cylinder 11. The top end of the telescopic rod 12 is fixedly connected to the bottom end of the lifting plate 5. The connection is fixed, and the handle 10 is rotated to drive the screw 8 to rotate. Under the action of the rotational force of the screw 8's outer wall thread, when the screw 8 rotates, the moving cylinder 9 can push the lifting plate 5 and the beaker placed on the lifting plate 5 to slide upward in a straight line under the limiting action of the telescopic rod 12 and the telescopic cylinder 11. This allows the beaker to be fitted onto the output end of the sampling valve 2 and to make tight contact with the bottom end of the sealing plate 3, thereby fixing and sealing the beaker and preventing the sample from splashing everywhere. This solves the problem that the sampling valve 2 of the existing reactor 1 does not have a protective structure when in use, and the sample will splash everywhere during the sampling process using the beaker.

[0023] In this embodiment, a connecting groove 19 is provided on the inner wall of the telescopic cylinder 11. A connecting block 20 is slidably embedded in the inner cavity of the connecting groove 19. The connecting block 20 is fixedly connected to the outer wall of the telescopic rod 12. Under the joint action of the connecting block 20 and the connecting groove 19, one end of the telescopic rod 12 can always be inserted into the inner cavity of the telescopic cylinder 11, which improves the stability of the device during use.

[0024] In this embodiment, the inner cavity of the connecting groove 19 and the outer wall of the connecting block 20 are adapted to each other and are both dovetail-shaped, which can keep one end of the connecting block 20 embedded in the inner cavity of the connecting groove 19, thus improving the stability of the connecting assembly during use.

[0025] In this embodiment, the outer circumference of the handle 10 is provided with anti-slip ridges, which can improve the roughness of the outer circumference of the handle 10, prevent the handle 10 from slipping out of the hand when rotating, and improve the stability of the device during use.

[0026] In this embodiment, a frame is provided at the top of the lifting plate 5. A lead screw 14 is rotatably connected to the left side of the inner cavity of the frame via a bearing. The other end of the lead screw 14 extends to the right end of the frame and is fixedly connected to a knob 15. The threads on the left and right sides of the outer wall of the lead screw 14 are arranged opposite to each other and are respectively screwed to sliders 16. The top of each of the two sliders 16 is provided with a clamping plate 6. A fixing groove 7 is opened on the side of the two clamping plates 6 that are close to each other. A bracket 13 is provided at the top of the lifting plate 5. By rotating the knob 15, the knob 15 drives the lead screw 14 to rotate, thereby causing the lead screw 14 to rotate. The opposing threads on the left and right sides of the outer wall generate opposing thread rotational forces, causing the two sliders 16 to slide simultaneously toward the middle of the lead screw 14 under the limiting action of the limiting groove 17 and the limiting block 18. Under the limiting action of the limiting groove 17 and the limiting block 18, the two sliders 16 respectively drive the two clamping plates 6 to slide simultaneously toward the top middle of the lifting plate 5. This causes the beaker placed on the bracket 13 to be clamped and fixed by the fixing groove 7, thereby preventing the beaker from falling during the up and down sliding process of the lifting plate 5, and improving the stability of the device during use.

[0027] In this embodiment, the inner cavity of the fixing groove 7 is inclined from the front and rear sides towards the middle, so that the fixing groove 7 and the beaker are in line contact, which can achieve clamping and fixing of the beaker.

[0028] In this embodiment, a limiting groove 17 is provided at the top of the lifting plate 5. Two limiting blocks 18 are slidably embedded in the inner cavity of the limiting groove 17. The two limiting blocks 18 are fixedly connected to the bottom ends of the two sliders 16 respectively. Under the joint action of the limiting groove 17 and the limiting blocks 18, the sliders 16 can be prevented from rotating with the lead screw 14 when the lead screw 14 rotates. The inner cavity of the limiting groove 17 and the outer wall of the limiting blocks 18 are adapted to each other and are both in the shape of "T". This allows one end of the limiting block 18 to always remain embedded in the inner cavity of the limiting groove 17, improving the stability of the limiting component during use.
