Description

Technical Field

[0001] This application relates to the field of detection device technology, specifically an online solvent recovery detection device. Background Technology

[0002] An online solvent recovery testing device is an automatic solvent parameter analysis instrument used to detect whether the quality of recovered solvent meets the standards.

[0003] Existing online refractometers are a type of online solvent detection device. They work by dripping recycled solvent into the sample slot of a connecting column, positioning the solvent at the prism position of the instrument, and then covering the sample slot with a light-shielding cover at the end of the connecting column. However, the light-shielding cover is only placed at the end of the connecting column and is not connected to it. Therefore, during detection, there is a possibility of accidental contact, causing the light-shielding cover to fall off the connecting column, which affects the normal operation of the prism and further affects the solvent detection results.

[0004] Therefore, this application provides an online solvent recovery detection device to solve the above problems. Utility Model Content

[0005] This application provides an online solvent recovery and detection device, which aims to solve the problems mentioned in the background art. The existing light-shielding cover is placed on the end of the connecting column to cover the sample tank for solvent detection. However, the light-shielding cover is only placed on the end of the connecting column and is not connected to the connecting column. Therefore, during detection, there is a possibility of accidental contact, causing the light-shielding cover to fall off the connecting column, which affects the normal operation of the prism and further affects the solvent detection results.

[0006] To achieve the above objectives, this application provides the following technical solution: an online solvent recovery detection device, comprising a detector, a connecting column disposed at the detection end of the detector for placing a sample, and a clamp disposed at one end of the detector and the connecting column for connecting the detector and the connecting column;

[0007] To prevent the light-shielding cover from accidentally falling off: a light-shielding cover is installed on the end of the connecting column away from the detector for light blocking; a limiting component is inserted into the outer wall of the connecting column to restrict the movement of the light-shielding cover; and a sealing ring is installed inside the light-shielding cover to prevent solvent leakage. When the detector end of the detector is connected to the connecting column via the clamp, and solvent is dripped into the sample slot of the connecting column, allowing the solvent to slide to the prism position of the detector end, the light-shielding cover needs to be placed on the outside of the connecting column away from the detector to block light. This can be done by pressing the insert block to position the light-shielding cover. When the limiting hole moves to the position of the insert block, the restoring force of the elastic block pushes the baffle, causing the insert block to insert into the limiting hole, thereby restricting the movement of the light-shielding cover and preventing accidental contact with the cover by external forces. When the light cover is applied, if the light-shielding cover detaches from the end of the connecting post, the sealing ring disposed between the connecting post and the light-shielding cover will be squeezed by the light-shielding cover and the connecting post, thereby sealing the connection between the connecting post and the light-shielding cover. This prevents liquid inside the connecting post from flowing out from the gap between the connecting post and the light-shielding cover when the connecting post is bumped. When the insert block is pressed to remove the light-shielding cover, the installation block is inserted into the slot, which can prevent the sealing ring from falling off and prevent the sealing ring from being contaminated by external pollutants.

[0008] Preferably, for the fixed installation of the light-shielding cover: the connecting post has a cavity inside for installing the limiting component, the inner wall of the cavity has a through hole, the limiting component includes a plug that passes through the through hole to limit the light-shielding cover, and the outer wall of the light-shielding cover has a limiting hole for inserting the plug. By inserting the plug into the limiting hole, the movement of the light-shielding cover is limited, thereby preventing the light-shielding cover from detaching from the connecting post.

[0009] Preferably, to maintain the stability of the insert block within the limiting hole: a baffle for limiting the movement of the insert block is fixedly connected to the end of the insert block away from the light-shielding cover, and an elastic block for pushing the baffle is provided on the side of the baffle away from the insert block. By compressing the elastic block, the insert block is pushed and a pushing force on the insert block is maintained, thereby stabilizing the insert block within the limiting hole.

[0010] Preferably, to prevent the sealing ring from falling off: a mounting block for installing the sealing ring is fixedly connected to the top of the inner wall of the light-shielding cover. The sealing ring is fixedly installed inside the light-shielding cover by the mounting block, preventing the sealing ring from falling off when the light-shielding cover is removed.

[0011] Preferably, the vertical cross-section of the mounting block is convex.

[0012] Preferably, to facilitate the replacement of the sealing ring: the outer wall of the sealing ring is provided with a slot for the mounting block to be inserted. By inserting the mounting block into the slot, the sealing ring can be quickly installed and removed, facilitating its replacement.

[0013] Preferably, the horizontal cross-section of the sealing ring is annular, and the vertical cross-section of the groove is convex.

[0014] This application utilizes a design incorporating a connecting post, a light-shielding cover, a limiting component, and a sealing ring. The light-shielding cover is positioned by pressing the insert block. When the limiting hole moves to the insert block position, the restoring force of the elastic block pushes the baffle, causing the insert block to insert into the limiting hole, thus restricting the movement of the light-shielding cover. This prevents the light-shielding cover from detaching from the end of the connecting post when accidentally bumped by external force. Simultaneously, the sealing ring positioned between the connecting post and the light-shielding cover is compressed by the light-shielding cover and the connecting post, sealing the area between them. This prevents liquid inside the connecting post from leaking out from the gap between the connecting post and the light-shielding cover when the connecting post is bumped. When the light-shielding cover is removed by pressing the insert block, the installation block, inserted into the slot, prevents the sealing ring from falling off and avoids contamination from external pollutants.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] This embodiment provides an online solvent recovery detection device, such as... Figure 1-8 As shown, the recycling and testing device includes a detector 1, a connecting column 2 set at the detection end of the detector 1 for placing samples, and a clamp 3 set at one end of the detector 1 and the connecting column 2 for connecting the detector 1 and the connecting column 2.

[0027] To prevent the light-shielding cover 4 from accidentally falling off: a light-shielding cover 4 is installed at the end of the connecting column 2 away from the detector 1 for light shielding; a limiting component 5 is inserted into the outer wall of the connecting column 2 to restrict the movement of the light-shielding cover 4; and a sealing ring 6 is installed inside the light-shielding cover 4 to prevent solvent leakage. After connecting the detector end of the detector 1 to the connecting column 2 via the clamp 3, and then dripping solvent into the sample groove of the connecting column 2, allowing the solvent to slide down to the prism position at the detector end of the detector 1, the light-shielding cover 4 needs to be placed on the outside of the end of the connecting column 2 away from the detector 1 to shield the light. At this time, the insert block 51 can be pressed to place the light-shielding cover 4. When the limiting hole moves to the position of the insert block 51, the restoring force of the elastic block 53 will push the baffle 52, causing the insert block 51 to insert into the interior of the limiting hole, thereby restricting the movement of the light-shielding cover 4 and preventing accidental contact by external forces. When the light-shielding cover 4 is in use, it may detach from the end of the connecting post 2. At the same time, the sealing ring 6, which is set between the connecting post 2 and the light-shielding cover 4, will be squeezed by the light-shielding cover 4 and the connecting post 2, thereby sealing the connection between the connecting post 2 and the light-shielding cover 4. This prevents the liquid inside the connecting post 2 from flowing out from the gap between the connecting post 2 and the light-shielding cover 4 when the connecting post 2 is collided with the connecting post 2. When the insert block 51 is pressed to remove the light-shielding cover 4, the installation block 7 is inserted into the slot 8, which can prevent the sealing ring 6 from falling off and prevent the sealing ring 6 from being contaminated by external pollutants.

[0028] Furthermore, the detector 1, connecting column 2, and clamp 3 together form the existing CYR-G880 online concentration detector for quality testing of the recovered solution.

[0029] Specifically, for the fixed installation of the light-shielding cover 4: a cavity for installing the limiting component 5 is provided inside the connecting column 2, and a through hole is provided on the inner wall of the cavity. The limiting component 5 includes an insert 51 that passes through the through hole to limit the light-shielding cover 4, and a limiting hole is provided on the outer wall of the light-shielding cover 4 for inserting the insert 51. By inserting the insert 51 into the limiting hole, the movement of the light-shielding cover 4 is limited, thereby preventing the light-shielding cover 4 from detaching from the connecting column 2. The size of the light-shielding cover 4 is adapted to the end of the connecting column 2 away from the detector 1. The through hole and the limiting hole are the same size and are adapted to the insert 51. At least two sets of limiting components 5 are symmetrically arranged, and the number and position of the limiting holes and through holes correspond to the number and position of the limiting components 5, respectively.

[0030] More specifically, to maintain the stability of the insert 51 within the limiting hole: a baffle 52 for limiting the movement of the insert 51 is fixedly connected to the end of the insert 51 away from the light-shielding cover 4, and an elastic block 53 for pushing the baffle 52 is provided on the side of the baffle 52 away from the insert 51. By compressing the elastic block 53, the insert 51 is pushed and a pushing force is maintained on the insert 51, thereby stabilizing the insert 51 within the limiting hole. Both the baffle 52 and the elastic block 53 are located inside the cavity. The size of the baffle 52 is 1.2 times the size of the through hole, and the elastic block 53 is an elastic rubber block that is always in a compressed state, thereby continuously providing the insert 51 with a pushing force to move away from the connecting post 2.

[0031] Specifically, to prevent the sealing ring 6 from falling off: a mounting block 7 for installing the sealing ring 6 is fixedly connected to the top of the inner wall of the light-shielding cover 4. The vertical cross-section of the mounting block 7 is convex. The sealing ring 6 is fixedly installed inside the light-shielding cover 4 by the mounting block 7, preventing the sealing ring 6 from falling off when the light-shielding cover 4 is removed. Multiple mounting blocks 7 are provided, and multiple mounting blocks 7 are distributed in a ring at equal intervals at the edge of the top of the inner wall of the light-shielding cover 4. The contact parts between the mounting blocks 7 and the light-shielding cover 4 are fixed by welding. The sealing ring 6 is made of elastic rubber. After the light-shielding cover 4 and the connecting post 2 are fixedly installed, the sealing ring 6 is squeezed and deformed to fill the gap between the connecting post 2 and the light-shielding cover 4, thereby preventing solvent from flowing out from the gap between the connecting post 2 and the light-shielding cover 4 when the connecting post 2 is accidentally touched.

[0032] More specifically, to facilitate the replacement of the sealing ring 6: the outer wall of the sealing ring 6 has a groove 8 for the insertion of the mounting block 7. The horizontal cross-section of the sealing ring 6 is annular, and the vertical cross-section of the groove 8 is convex. By inserting the mounting block 7 into the groove 8, the sealing ring 6 can be quickly installed and removed, facilitating its replacement. The size of the groove 8 is 1.2 times the size of the mounting block 7, and the inner wall of the groove 8 is smooth, thus facilitating the insertion of the mounting block 7. The number and position of the grooves 8 correspond to the number and position of the mounting blocks 7, respectively. One end of the groove 8 penetrates the outer wall of the sealing ring 6. Therefore, when installing the sealing ring 6, the mounting block 7 can be inserted into the sealing ring 6 through the groove 8. When disassembling, it is also convenient to separate the sealing ring 6 from the mounting block 7. When installing the sealing ring 6, first insert one of the mounting blocks into the groove 8 on one side of the sealing ring 6. 7. Next, compress the sealing ring 6 so that the other slots 8 can be inserted into the corresponding mounting blocks 7. When all the slots 8 have mounting blocks 7 inserted inside, the sealing ring 6 is fixedly installed. At this time, the position of the mounting blocks 7 does not affect the sealing ring 6 from returning to its circular shape under its own restoring force, thereby maintaining the seal between the sealing ring 6 and the connecting post 2 and the light shield 4. When removing the sealing ring 6, you can directly pull the sealing ring 6 to separate the slots 8 from the mounting blocks 7. The sealing ring 6 will return to its original shape under its own elastic force.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
