Description

Technical Field

[0001] The invention relates to the technical field of quality detection assistance, in particular to a quality detection device for the research and development of a composite cerium-based catalyst. Background Art

[0002] The purpose of cerium-based catalyst quality testing equipment is to determine the catalytic activity level of cerium-based catalysts in specific reactions. By measuring indicators such as the reaction rate and conversion rate of the catalyst, it can be determined whether it can effectively promote the target reaction.

[0003] In the detection of cerium-based catalysts and other related fields, micro-syringes are often used for injection operations; however, in actual applications, the problem of insufficient smoothness of the piston of the micro-syringe is prominent. When the piston is not smooth, the time for absorbing and injecting the sample will be prolonged during the sample absorption process, and the operator needs to spend more time and energy to overcome the piston resistance and adjust the speed, which not only reduces the experimental efficiency, but also increases the risk of errors during the experiment; in addition, when the piston is not smooth, the operator will unconsciously increase the force to push or pull the piston, which will cause damage to the syringe and the instrument connected to it. For example, when connected to the chromatograph injection port, improper force will damage the sealing components of the injection port or cause the syringe injection head to bend or break, affecting the normal use and life of the instrument;

[0004] In addition, during actual use, the needle of the micro-injector is prone to deformation. When the needle is deformed, it will have many adverse effects on the experimental process and results; first, the deformed needle will change the accuracy of the injection, and the change in the shape of the needle will affect the depth and angle of its insertion into the injection port, resulting in unstable injection volume; secondly, the deformation of the needle will increase the difficulty and risk of operation. The deformed needle will scratch the injection port or other components during the insertion and removal process, causing damage to the instrument.

[0005] Therefore, we proposed a quality inspection device for the research and development of composite cerium-based catalysts to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a quality detection device for the research and development of a composite cerium-based catalyst to solve the problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A quality inspection device for the research and development of a composite cerium-based catalyst, comprising: a quality inspection device, an injection port, an injection rod, a solution sleeve, and a needle, wherein the injection port is fixedly connected to the quality inspection device, the injection rod is inserted into the solution sleeve, and the needle is fixedly connected to the bottom of the solution sleeve, and further comprising: an auxiliary component, a first component, and a second component, wherein the first component is arranged on a horizontal plane of the auxiliary component, and the second component is arranged on a vertical plane of the auxiliary component;

[0008] The first component is mainly used to detect the injection smoothness of the micro-injector;

[0009] The second component is mainly used to detect the deformation of the needle on the micro-injector and to correct and adjust the micro-deformation of the needle;

[0010] As an improvement, the auxiliary component includes a main body block arranged on the quality inspection device, the main body block is provided with a horizontal slide groove and a vertical slide groove, the horizontal slide groove is connected with the vertical slide groove, and a guide cone is fixedly connected to the bottom of the vertical slide groove;

[0011] As an improvement, a transverse column is connected in transverse sliding connection in the transverse slide groove, a pushing smoothness feedback cavity is arranged on the same horizontal plane as the transverse column, one end of the transverse column is inserted into the pushing smoothness feedback cavity, and the other end of the transverse column is fixedly connected to a bevel body.

[0012] As an improvement, one end of the transverse displacement column located in the pushing smoothness feedback cavity is fixedly connected to a magnet sheet, a magnet transmission group is slidably connected in the pushing smoothness feedback cavity, and one end of the pushing smoothness feedback cavity away from the transverse displacement column is threadedly connected to a threaded pushing column.

[0013] As an improvement, the first component includes a sleeve column fixedly connected to the main body block, and a cover column member is threadedly connected to the top of the sleeve column.

[0014] As an improvement, a vertical moving body is vertically slidably connected in the sleeve column, the lower part of the vertical moving body is vertically slidably connected in the vertical slide groove, a supporting groove is provided at the top of the vertical moving body, an inclined groove is provided at the lower part of the vertical moving body, and a return spring is fixedly connected to the bottom of the vertical moving body.

[0015] As an improvement, the second component includes an auxiliary spring body, the auxiliary spring body is fixedly connected to the top of the sleeve column, and a vertical detection through slot is opened on the vertical movable body.

[0016] As an improvement, a deformable conformal through groove is provided on the inclined surface.

[0017] Compared with the prior art, the present invention provides a quality detection device for the research and development of a composite cerium-based catalyst, which has the following beneficial effects:

[0018] 1. The present application can effectively detect the smoothness of the movement of the piston on the injection rod in the solution sleeve through the first component. This operation of detecting the smoothness of the piston of the micro-injection syringe before injecting the quality inspection agent can effectively avoid the situation in which the time for drawing and injecting samples is prolonged due to the unsmooth movement of the piston during the sample drawing process, and the operator needs to spend more time and energy to overcome the piston resistance and adjust the speed, thereby reducing the experimental efficiency and increasing the risk of experimental errors. At the same time, it can effectively avoid the situation in which when the piston is not smooth, the operator will unconsciously increase the force to push or pull the piston to cause damage to the syringe and the instrument connected thereto, especially the sealing parts of the injection port or the injection head of the syringe are bent or broken, affecting the normal use of the instrument.

[0019] 2. The present application can perform deformation detection on the needle inserted into the vertical detection slot through the setting of the second component. At the same time, the slightly deformed needle can be corrected through the vertical detection slot and the deformability conformal slot by the upward movement of the vertical movable body and the lateral movement of the inclined body. This is different from the prior art that the needle is operated without detection. The change in the shape of the needle affects the depth and angle of insertion into the injection port, thereby causing unstable injection volume. Secondly, it avoids needle deformation to increase the difficulty and risk of operation. The deformed needle may scratch the injection port or other components during insertion and removal, causing damage to the instrument.

[0020] 3. In the present application, through the design of the magnet sheet and the magnet transmission group, when the threaded pushing column rotates in the pushing smoothness feedback cavity and is driven by the magnet sheet and the magnet transmission group to move the transverse column to correct the deformation of the needle, since the movement is through the magnetic repulsion between the magnet sheet and the magnet transmission group as the moving medium, there is a certain buffer in the pushing process, which can effectively avoid the breakage caused by excessive force when correcting the needle, and effectively ensure the stability and safety of the deformability adjustment.

The first component 5 includes a sleeve column 501 fixedly connected to the main body block 401, a cover column 502 is threadedly connected to the top of the sleeve column 501, a vertical moving body 503 is vertically slidably connected in the sleeve column 501, and the lower middle part of the vertical moving body 503 is vertically slidably connected in the vertical slide groove 403. A supporting groove 504 is provided at the top of the vertical moving body 503, and an oblique groove 505 is provided at the lower middle part of the vertical moving body 503. A return spring 506 is fixedly connected to the bottom of the vertical moving body 503, and a transverse column 500 is transversely slidably connected in the transverse slide groove 402. 8. A pushing smoothness feedback cavity 507 is arranged on the same horizontal plane as the transverse column 508, one end of the transverse column 508 is inserted into the pushing smoothness feedback cavity 507, and the other end of the transverse column 508 is fixedly connected with a ramp body 509, one end of the transverse column 508 located in the pushing smoothness feedback cavity 507 is fixedly connected with a magnet sheet 510, a magnet transmission group 511 is slidably connected in the pushing smoothness feedback cavity 507, and one end of the pushing smoothness feedback cavity 507 away from the transverse column 508 is threadedly connected with a threaded pushing column 512, the second component 6 includes an auxiliary spring body 601, the auxiliary spring body 601 is fixedly connected to the top of the sleeve column 501, a vertical detection through groove 602 is opened on the vertical moving body 503, and a deformable conformal through groove 603 is opened on the ramp body 509.

[0045] in:

[0046] The first component 5 is mainly used to detect the injection smoothness of the micro-injection syringe.

[0047] The pushing smoothness feedback cavity 507 is made of a transparent material, and can be implemented as a plastic / glass material.

[0048] The magnet transfer groups 511 are grouped into two, and multiple groups can be provided according to specific circumstances.

[0049] The second component 6 is mainly used to detect the deformation of the needle 303 on the micro-injector and to correct and adjust the micro-deformation of the needle 303 .

[0050] The deformable conformal through slot 603 is mainly used in conjunction with the vertical detection through slot 602 .

[0051] Everything in the above example works like this:

[0052] In the initial state: the needle 303 on the solution sleeve 302 is not inserted into the vertical detection slot 602, the return spring 506 and the auxiliary spring body 601 are in a normal relaxed state; the top of the inclined surface of the oblique groove 505 is located in the horizontal slide groove 402, and the rest of the inclined surface is located in the vertical slide groove 403, that is, the inclined surface body 509 does not squeeze the vertical moving body 503 through the oblique groove 505. Please refer to the attached Figure 5 .

[0053] It should be noted that the injection smoothness of the micro-injector and the deformation of the needle 303 are detected simultaneously. For the convenience of explanation, they are described separately below.

[0054] The following is the working process of the second component 6:

[0055] When testing whether the needle 303 is deformed, the operator first inserts the needle 303 on the solution sleeve 302 into the vertical testing slot 602. The insertion is divided into two situations:

[0056] First, the needle 303 is greatly deformed and cannot be fully inserted into the vertical detection slot 602; in this case, the operator will determine that the needle 303 cannot be used and will perform a subsequent replacement process;

[0057] Second, the needle 303 is slightly deformed and can be fully inserted into the vertical detection slot 602, but there is resistance when it is pulled out of the vertical detection slot 602; at this time, the operator needs to repair the deformation of the needle 303 through the second component 6; the details are as follows:

[0058] First, insert the needle 303 into the vertical detection groove 602 again, then screw the cover column 502 onto the sleeve column 501, and then the operator further screws the threaded pushing column 512 on the pushing smoothness feedback cavity 507 into the pushing smoothness feedback cavity 507. At this time, the threaded pushing column 512 will move with the magnet transmission group 511 in the pushing smoothness feedback cavity 507. Due to the principle that magnets have the same polarity and repel each other, the magnet transmission group 511 will push the transverse column 508 through the magnet sheet 510 to move horizontally in the transverse groove 402 opened on the main block 401. During the movement, the inclined surface 509 will move with the inclined groove 506 opened on the vertical moving body 503. 05 cooperates to push the vertical moving body 503 upward. Further, when the inclined plane body 509 moves right and the solution sleeve 302 moves upward, the needle 303 will move relative to the deformable conformal groove 603 provided on the inclined plane body 509. That is, at this time, the needle 303 with slight deformation will be forced to bend and deform in the cooperation between the vertical detection groove 602 and the deformable conformal groove 603 to reset the state. It should be noted that when the inclined plane body 509 moves to the left, the repair work of the needle 303 can still be carried out; and the above operation can be carried out after adjusting the multiple positions of the needle 303 inserted into the vertical detection groove 602, so as to complete the slight deformation adjustment work of the needle 303.

[0059] Furthermore, the present application can perform deformation detection on the needle 303 inserted into the vertical detection slot 602 through the setting of the second component 6, and at the same time, the slightly deformed needle 303 can be corrected through the vertical detection slot 602 and the deformability conformal slot 603 by the upward movement of the vertical movable body 503 and the lateral movement of the bevel body 509. This is different from the prior art that the needle 303 is not detected and the work is carried out. The change in the shape of the needle 303 affects the depth and angle of insertion into the injection port 2, thereby causing unstable injection volume; secondly, it avoids deformation of the needle 303 to increase the difficulty and risk of operation. The deformed needle 303 may scratch the injection port 2 or other components during the insertion and removal process, causing damage to the instrument.

[0060] Please refer to the above working process Figure 2 , Figure 3 , Figure 5 .

[0061] The following is the working process of the first component 5:

[0062] When checking the injection smoothness of the micro-injector, that is, checking the movement smoothness of the injection rod 301 in the solution sleeve 302, the operator further screws the threaded pushing column 512 on the pushing smoothness feedback cavity 507 into the pushing smoothness feedback cavity 507. At this time, the threaded pushing column 512 will move with the magnet transmission group 511 in the pushing smoothness feedback cavity 507. Due to the principle that magnets have the same polarity repulsion, the magnet transmission group 511 will push the lateral column 508 through the magnet sheet 510. The vertical moving body 503 moves horizontally in the horizontal slide groove 402 provided on the main body block 401. During the movement, the inclined surface body 509 cooperates with the inclined groove 505 provided on the vertical moving body 503 to push the vertical moving body 503 to move upward. Furthermore, since it is known that the cover column 502 is fixed to the sleeve column 501 by a screw, when the vertical moving body 503 moves upward, the solution sleeve 302 will be dragged upward through the supporting groove 504, and the injection rod 301 will be gradually passively pressed into the solution sleeve 302. At this time, the solution in the solution sleeve 302 is The washing solution will be injected from the needle 303 into the bottom of the vertical slide 403, and transferred out from the guide cone 404 and the transfer port of the device; further, the operator only needs to observe whether the magnets in the magnet transfer group 511 composed of two magnets are close to each other during movement. This is because if the smoothness is not enough, the two magnets will stick together due to the unsmooth movement, that is, the present application can effectively detect the smoothness of the movement of the piston on the injection rod 301 in the solution sleeve 302 through the first component 5. This operation of detecting the smoothness of the piston of the micro-injector before injecting the quality inspection agent can effectively avoid the situation in which the unsmooth movement of the piston during the sample aspiration process will prolong the time of aspirating and injecting the sample, and the operator needs to spend more time and energy to overcome the piston resistance and adjust the speed, thereby reducing the experimental efficiency and increasing the risk of experimental errors; at the same time, it can effectively avoid the situation in which when the piston is not smooth, the operator will unconsciously increase the force to push or pull the piston to cause damage to the syringe and the instrument connected thereto, especially the sealing component of the injection port or the syringe injection head is bent or broken, affecting the normal use of the instrument.

[0063] Furthermore, the present application adopts the design of the magnet sheet 510 and the magnet transmission group 511. When the threaded pushing column 512 rotates in the pushing smoothness feedback cavity 507 and is transmitted by the magnet sheet 510 and the magnet transmission group 511 to move the transverse column 508 to correct the deformation of the needle 303, since the movement is through the magnetic repulsion between the magnet sheet 510 and the magnet transmission group 511 as the moving medium, there is a certain buffer in the pushing, which can effectively ensure that the breakage caused by excessively fast and heavy force when correcting the needle 303 is avoided, and the stability and safety of the deformability adjustment are effectively guaranteed.
