Description

Technical Field

[0001] This utility model relates to the field of sampling and detection technology, specifically a sampling and detection device for a reaction vessel. Background Technology

[0002] In the chemical and pharmaceutical industries, it is necessary to regularly monitor the condition of reaction materials, such as testing the pH of the materials or the concentration of certain substances, in order to facilitate the next step of the operation.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: the existing sampling and detection device for reactors does not have a convenient sampling effect. Since there are many reactors in the workshop, each sampling and detection takes a lot of time. The inconvenient sampling method further prolongs the sampling and detection time, and its practicality is not ideal. It is urgent to improve it. Therefore, we propose a sampling and detection device for reactors. Utility Model Content

[0004] The purpose of this invention is to provide a sampling and detection device for a reaction vessel, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sampling and detection device for a reaction vessel, comprising a vessel body, wherein a sampling cylinder is connected to the bottom of one side wall of the vessel body, a pressure plate is placed on one side of the sampling cylinder, and a movable plate is placed on one side of the pressure plate;

[0006] A sleeve is fixedly installed inside the sampling tube, and a liquid pipe is connected to the bottom of the sampling tube, with a valve installed on the liquid pipe;

[0007] The sleeve has an inner rod that can be moved through both sides, and the inner rod is fixedly connected to the pressure plate. A sealing sleeve is fixedly fitted on the area of ​​the inner rod near the sleeve. A sealing plate is fixedly installed on the inner end of the inner rod, and a sealing gasket is fixedly installed on the outer side of the sealing plate.

[0008] T-shaped rods are movably inserted through both sides of the top of the pressure plate, and the T-shaped rods are fixedly connected to the vessel body. A spring is sleeved on the outside of the T-shaped rods.

[0009] The pressure plate has a groove on its lower side near the T-shaped rod, and a movable plate is placed in the groove. It can be used in conjunction with components such as the pressure plate, spring, and sealing plate. During the use of the sampling and detection device, if sampling is required, the pressure plate can be squeezed towards the sampling cylinder by hand. The pressure plate can drive the inner rod to move inward, and the inner rod can drive the sealing plate to move inward, so that the liquid in the vessel enters the sampling cylinder through the gap between the sealing plate and the vessel body. Then, the pressure plate is released, and the spring tension causes the sealing plate to re-contact the sealing gasket and adhere to the inner wall of the vessel. The valve can then be opened to release the liquid. This sampling structure is easy to operate, effectively improves the efficiency of batch sampling, and meets the usage requirements.

[0010] As an optional solution to the technical solution of this application, locking rods are fixedly installed on both sides of the top of the movable plate. The locking rods move through the pressure plate and are inserted into the pre-set slots on the lower side of the T-shaped rod. A tension spring is sleeved on the outside of the locking rod, and the two ends of the tension spring are fixedly connected to the movable plate and the pressure plate respectively. The locking rods and the movable plate can be used together to apply tension to the movable plate, so that the movable plate maintains a certain height and the locking rod is locked in the slot of the T-shaped rod. If the pressure plate needs to be moved, the finger can be pressed against the movable plate, and the force can be applied simultaneously to move the movable plate and the locking rod downward to release the limit. This structure can prevent non-sampled external forces from pressing the pressure plate. Conversely, after the pressure plate is released, the pressure plate and the end of the T-shaped rod are attached. Releasing the movable plate can make the locking rod re-lock in the slot. This limiting mechanism is designed to be easy to adjust.

[0011] As an optional solution to the technical solution of this application, the top of the vessel is integrally formed and connected to a material inlet, and an indicator sign is fixedly installed on one side of the front wall of the vessel. The indicator sign is fixed by welding and can be used to add raw materials through the material inlet. At the same time, the indicator sign is used to inform the operator of the corresponding usage method, so as to facilitate understanding and use.

[0012] As an optional solution to the technical solution of this application, a finger groove is provided in the middle of the outer wall of the movable plate, and an anti-slip texture is provided in the finger groove. By pressing the finger into the finger groove and increasing the friction through the anti-slip texture, it is easy to adjust the force applied by the finger.

[0013] As an optional solution to the technical solution of this application, the two ends of the spring are fixedly connected to the vessel body and the pressure plate respectively. The fixed connection of the two ends of the spring can prevent the spring from slipping off at both ends during the extension and contraction, and avoid frequent reinstallation of the spring assembly.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model discloses a sampling and detection device for a reaction vessel. It is equipped with a pressure plate, a spring, and a sealing plate. During use, when sampling is required, the pressure plate can be squeezed towards the sampling cylinder by hand. The pressure plate moves the inner rod inward, which in turn moves the sealing plate inward, allowing the liquid in the vessel to enter the sampling cylinder through the gap between the sealing plate and the vessel body. Afterward, the pressure plate is released, and the spring tension causes the sealing plate to re-apply to the sealing gasket and adhere to the inner wall of the vessel. The valve can then be opened to release the liquid. This sampling structure is convenient to operate, effectively improves batch sampling efficiency, and meets usage requirements.

[0016] 2. This utility model discloses a sampling and detection device for a reaction vessel. It is equipped with a locking rod and a movable plate. A tension spring applies force to the movable plate, maintaining it at a certain height and locking the locking rod in the slot of the T-shaped rod. To move the pressure plate, a finger can be pressed against the movable plate, simultaneously applying force to move the movable plate and locking rod downwards to release the limit. This structure prevents external forces other than sampling from pressing against the pressure plate. Conversely, after releasing the pressure plate, once it is in contact with the end of the T-shaped rod, releasing the movable plate allows the locking rod to re-lock in the slot. This limiting mechanism is designed for easy adjustment. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-3This utility model provides a technical solution: a sampling and detection device for a reaction vessel, including a vessel body 1. The top of the vessel body 1 is integrally formed and connected to a material inlet 11. An indicator 12 is fixedly installed on one side of the front wall of the vessel body 1, and the indicator 12 is fixed by welding. Raw materials can be added through the material inlet 11. The indicator 12 also informs the operator of the corresponding usage method for easy understanding and use. A sampling cylinder 2 is connected to the bottom of one side wall of the vessel body 1. A pressure plate 4 is placed on one side of the sampling cylinder 2, and a movable plate 5 is placed on one side of the pressure plate 4. A sleeve 21 is fixedly installed inside the sampling cylinder 2. A liquid pipe 22 is connected to the bottom of the sampling cylinder 2, and a valve 23 is installed on the liquid pipe 22. Two valves are installed inside the sleeve 21. An inner rod 41 is movably inserted through both sides of the pressure plate 4, and the inner rod 41 is fixedly connected to the pressure plate 4. A sealing sleeve 44 is fixedly fitted on the area of ​​the inner rod 41 near the sleeve 21. A sealing plate 42 is fixedly installed on the inner end of the inner rod 41, and a sealing gasket 43 is fixedly installed on the outer side of the sealing plate 42. T-shaped rods 3 are movably inserted through both sides of the top of the pressure plate 4, and the T-shaped rods 3 are fixedly connected to the vessel body 1. A spring 31 is fitted on the outer side of the T-shaped rod 3. The two ends of the spring 31 are fixedly connected to the vessel body 1 and the pressure plate 4, respectively. The fixed connection of the two ends of the spring 31 can prevent the spring 31 from slipping off through its two ends during the extension and retraction, and avoid frequent reinstallation of the spring 31 assembly. A groove 45 is opened on the lower side of the pressure plate 4 near the T-shaped rod 3, and a movable plate 5 is placed in the groove 45.

[0024] In this technical solution, components such as pressure plate 4, spring 31, and sealing plate 42 can be used together. During the use of the sampling and testing device, if sampling is required, the pressure plate 4 can be squeezed towards the sampling cylinder 2 by hand. The pressure plate 4 can drive the inner rod 41 to move inward, and the inner rod 41 can drive the sealing plate 42 to move inward, so that the liquid in the vessel enters the sampling cylinder 2 through the gap between the sealing plate 42 and the vessel body 1. Then, the pressure plate 4 is released, and the tension of the spring 31 causes the sealing plate 42 to re-abut against the sealing gasket 43 and adhere to the inner wall of the vessel. Then, the valve 23 is opened to release the liquid. This sampling structure is easy to operate, effectively improves the efficiency of batch sampling, and meets the usage requirements.

[0025] In some technical solutions, locking rods 52 are fixedly installed on both sides of the top of the movable plate 5. The locking rods 52 are movably inserted through the pressure plate 4, and the top of the locking rods 52 are inserted into the pre-set slots 32 on the lower side of the T-shaped rod 3. A tension spring 53 is sleeved on the outside of the locking rods 52, and the two ends of the tension spring 53 are fixedly connected to the movable plate 5 and the pressure plate 4 respectively. A finger groove 51 is opened in the middle of the outer wall of the movable plate 5, and anti-slip texture is opened in the finger groove 51. By pressing the finger into the finger groove 51, the friction is increased by the anti-slip texture, which facilitates the adjustment of the finger force.

[0026] In this technical solution, components such as the locking rod 52 and the movable plate 5 can be used together. The tension spring 53 can apply tension to the movable plate 5 to maintain a certain height and make the locking rod 52 lock in the slot 32 of the T-shaped rod 3. If it is necessary to move the pressure plate 4, you can touch the movable plate 5 with your finger and apply force to move the movable plate 5 and the locking rod 52 downward to release the limit. This structure can prevent non-sampling external forces from pressing the pressure plate 4. Conversely, after releasing the pressure plate 4, wait for the pressure plate 4 to fit with the end of the T-shaped rod 3, and release the movable plate 5 to make the locking rod 52 lock in the slot 32 again. This limiting mechanism is designed to be easy to adjust.

[0027] Working principle: It should be noted that this utility model is a sampling and detection device for a reaction vessel. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0028] When a sampling and testing device for a reaction vessel is used, the sampling and testing device is integrally formed and installed on one side of the reaction vessel. During use, if sampling is required for testing, it can be sampled and tested through this device.

[0029] By incorporating a pressure plate 4, a spring 31, and a sealing plate 42, the sampling and testing device allows for convenient sampling during operation. When sampling is required, the pressure plate 4 can be squeezed towards the sampling cylinder 2 by hand. The pressure plate 4 moves the inner rod 41 inward, which in turn moves the sealing plate 42 inward, allowing the liquid in the vessel to enter the sampling cylinder 2 through the gap between the sealing plate 42 and the vessel body 1. Afterward, the pressure plate 4 is released, and the tension of the spring 31 causes the sealing plate 42 to re-apply to the sealing gasket 43 and adhere to the inner wall of the vessel. The valve 23 can then be opened to release the liquid. This sampling structure is convenient to operate, effectively improves batch sampling efficiency, and meets the usage requirements. By setting up a locking rod 52 and a movable plate 5, the movable plate 5 can be pulled by a tension spring 53 to maintain a certain height and make the locking rod 52 locked in the slot 32 of the T-shaped rod 3. If it is necessary to move the pressure plate 4, the finger can be pressed against the movable plate 5, and the force can be applied simultaneously to move the movable plate 5 and the locking rod 52 downward to release the limit. This structure can prevent non-sampling external forces from pressing the pressure plate 4. Conversely, after releasing the pressure plate 4, when the pressure plate 4 is in contact with the end of the T-shaped rod 3, releasing the movable plate 5 can make the locking rod 52 re-lock in the slot 32. This limiting mechanism is designed to be easy to adjust.
