Description

Technical Field

[0001] The invention relates to the technical field of chemical detection, and specifically discloses an online sampling and detection device for a rust remover. Background Art

[0002] In the existing production and preparation process of rust removers, it is necessary to regularly extract a certain amount of sample liquid in the reactor through a sampling tube, and then take the sample liquid to the testing room for step-by-step testing of its various properties and effects, especially the rust removal effect of the sample liquid and the corrosion effect on metals. It is usually necessary to manually immerse rusty samples and samples with smooth surfaces in the rust remover sample liquid for reaction, and then take them out after the reaction to observe the surface conditions of the samples. This makes the testing process of the rust remover cumbersome and time-consuming, and it is impossible to achieve its online rapid detection.

[0003] For example, the invention patent with application number 2023230688227 discloses a sampling device for rust remover production, which includes a test tube placement box, a placement slot is provided inside the test tube placement box, a sampling test tube is connected inside the placement slot, and a box cover is provided on the upper surface of the test tube placement box; the inner top wall of the box cover is fixedly connected with a horizontal plate, the lower surface of the horizontal plate is fixedly connected with an open box, the inner top wall of the open box is fixedly connected with a spring, the end of the spring away from the open box is fixedly connected with a sealing ring, and the inner wall of the sealing ring is provided with a rubber sleeve. The sampling device disclosed in this patent extracts the sample liquid inside the reactor through a sampling test tube, and then sends it as a whole to the detection room for one-by-one detection of various parameters and performances, which makes it impossible to detect and sample the rust remover, and in the process of continuous production and preparation of the rust remover, it seriously restricts the production efficiency of the rust remover. Therefore, in view of the shortcomings of the existing sampling and testing process in the production and preparation of rust removers, the present application proposes an online sampling and testing device for rust removers to realize automatic online sampling and various online testing processes during the production of rust removers, thereby ensuring the continuous production efficiency of rust removers. Summary of the invention

[0004] The present invention aims to provide an online sampling and detection device for a rust remover, so as to realize automatic sampling and detection in the production and preparation process of the rust remover and ensure the continuous production efficiency of the rust remover.

[0005] The present invention is achieved through the following technical solutions: An online sampling and testing device for rust remover comprises a reactor and a sampling tube, one end of the sampling tube is connected to the reactor, and the other end is connected to a sampling pump, a discharge end of the sampling pump is connected to a vertical downward testing sample tube, a vertical and connected sample insertion tube is arranged on the testing sample tube, a blocking column is movably arranged at the open end of the sample insertion tube, and a first spring is connected between the blocking column and the inner end of the sample insertion tube; A detection mechanism is arranged beside the detection sample tube, and the detection mechanism includes a box body, a transmission assembly is arranged in the box body, a plurality of movable carriers are connected to the transmission assembly at equal intervals, each of the movable carriers is slidably connected with a sample fixing plug via a second spring and a slide rail, an iron column sample is arranged in the sample fixing plug tube toward the open end of the sample insertion tube, and a fastener for fixing the iron column sample is arranged on the sample fixing plug tube, a through hole aligned with the detection sample tube is opened on the box body, a push rod assembly is arranged on the box body for pushing the sample fixing plug aligned with the through hole to one side of the through hole, and a transparent observation port for observing the iron column sample after the reaction is arranged above the through hole.

[0006] As a further configuration of the above scheme, the detection sample tube includes an upper detection tube and a lower sample arrangement tube, an electromagnetic valve is arranged between the upper detection tube and the lower sample arrangement tube, and the sample insertion tube is arranged on the upper detection tube.

[0007] As a further configuration of the above scheme, a pH value detection sensor and a viscosity detection sensor are provided on the upper detection tube located above the sample insertion tube, and the pH value detection sensor and the viscosity detection sensor are both electrically connected to a control box.

[0008] As a further configuration of the above scheme, two sample insertion tubes are provided on the upper detection tube, and two through holes are provided on the box body and are aligned with the two sample insertion tubes one by one.

[0009] As a further configuration of the above solution, the diameter of the detection sample tube is larger than the diameter of the sample fixing insert.

[0010] As a further configuration of the above scheme, one end of the sample fixing insert connected to the iron column sample is provided with a rubber sealing ring having a diameter equal to the diameter of the sample fixing insert.

[0013] As a further configuration of the above solution, a sample replacement port is provided on the box body opposite to the transparent observation port.

[0014] In the rust remover online sampling and detection device disclosed in the present invention, during the rust remover preparation process, the rust remover inside the reactor is quantitatively extracted into the detection sample tube through a sampling pump, and then the transmission component is started to transport the iron column sample for detection to be aligned with the through hole on the box body, and then the push rod component is started to push the sample fixing insert here to one side of the through hole, so that the iron column sample extends from the through hole and extends into the sample fixing insert.

[0015] After the iron column sample enters the sample fixing insert, it will squeeze the blocking column, so that the blocking column overcomes the supporting force of the first spring and shrinks inward, so that the iron column sample is inserted into the flow channel of the test sample tube.

After the reaction is completed, the iron column sample automatically withdraws and can seal the sample fixing plug-in tube to prevent the sample liquid from flowing out. The withdrawn iron column sample can be transported to the transparent observation port for naked eye detection or camera to detect and judge the surface condition. The whole detection process has a high degree of automation and fast inspection efficiency.

[0018] After the rust removal or corrosion effect detection of one iron column sample is completed, the detection mechanism in the present invention can immediately transport the next group of iron column samples to the corresponding position to wait for the next detection without any pause in between. It has a good continuous detection effect when used in the continuous production and preparation process of rust remover. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 7 , and describes the application in detail with reference to embodiments. Example 1

[0023] Example 1 discloses an online sampling and detection device for rust remover, see the attached Figure 1 and attached Figure 2, including a frame 1, a reactor 2 for preparing rust remover is fixedly installed on the upper end of the frame 1, a sampling tube 3 is connected to one side of the lower end of the reactor 2, and a sampling pump 4 fixed on the upper end of the frame 1 is connected to the top of the sampling tube 3, and then a vertical downward detection sample tube 5 is connected to the liquid outlet of the sampling pump 4. A detection mechanism 6 fixedly connected to the frame 1 is arranged beside the detection sample tube 5, and a control box 7 with a display is also arranged on one side of the frame 1. In the process of stirring the reactor 2 to prepare the rust remover, the sampling pump 4 is started regularly, and a certain amount of rust remover sample liquid is quantitatively extracted into the detection sample tube 5 through the sampling tube 3, and then the detection mechanism 6 detects its various properties, and the detection results are fed back to the display on the control box 7, so that the operator can directly view it.

[0024] Reference Figure 3 and attached Figure 4 The detection sample tube 5 includes an upper detection tube 501 and a lower sample tube 502, and an electromagnetic valve 503 is arranged between the upper detection tube 501 and the lower sample tube 502, and the electromagnetic valve 503 is used to actively control the retention or discharge of the sample liquid in the detection sample tube 5. Two sample insertion tubes 504 vertically connected to the upper detection tube 501 are arranged at intervals in the middle part of the upper detection tube 501, and one end of the sample insertion tube 504 is sealed and the other end is open, and the diameter of the sample insertion tube 504 is smaller than the diameter of the upper detection tube 501. A first spring 505 is connected to the inner wall of the sealed end of the sample insertion tube 504, and a blocking column 506 that seals the open end of the sample insertion tube 504 is connected to the movable end of the first spring 505, so that under normal circumstances, the first spring 505 pushes the blocking column 506 into the open end of the sample insertion tube 504, thereby completely sealing the open end of the sample insertion tube 504 to prevent the sample liquid from flowing out. In addition, in order to perform online detection of parameters such as pH value and viscosity of the rust remover sample liquid, a pH value detection sensor 507 and a viscosity detection sensor 508 are provided in the upper detection tube 501 above the two sample insertion tubes 504, and both are electrically connected to the control box 7.

[0025] Reference Figures 5 to 7The detection mechanism 6 includes a vertically arranged box 601, a transmission roller 602 is rotatably arranged at both the upper and lower ends of the box 601, and a servo motor 603 is connected to the end of one of the transmission rollers 602, and then a transmission belt 604 is arranged between the two transmission rollers 602. A plurality of movable carriers 605 are connected to the outer surface of the transmission belt 604 at equal intervals, and the distance between two adjacent movable carriers 605 is equal to the spacing between the two sample insertion tubes 504. A slide rail 606 parallel to the axial direction of the driving roller 602 is provided on the movable carrier 605, and a slider 607 is slidably provided on each slide rail 606, and then a sample fixing insert 608 is connected to or integrally formed at the end of the slider 607, and then an iron column sample with a rusty surface and an iron column sample 609 with a smooth surface are respectively inserted into two adjacent sample fixing inserts 608, and a fastener 610 is also provided at the outer end of the sample fixing insert 608. The specific fastener 610 can be a fastening bolt, and the inner end of the iron column sample 609 into which the iron column sample 609 is inserted can be pressed and fixed by twisting the fastener 610. In order to ensure that the iron column sample 609 can be smoothly inserted into the corresponding sample insertion tube 504, the diameter of the iron column sample 609 is set smaller than the inner diameter of the sample insertion tube 504, and a rubber sealing ring 611 with a diameter equal to the inner diameter of the sample insertion tube 504 is concentrically arranged at the outer end of the sample fixing insert 608, so that when the sample fixing insert 608 is inserted into the sample insertion tube 504, one end of the rubber sealing ring 611 can also be inserted therein to seal the open end to prevent the rust remover sample liquid from flowing out.

[0026] In addition, a second spring 612 is connected to the end of the movable carrier 605 away from the side of the iron column sample 609, and the end of the second spring 612 is connected to the slider 607 or the sample fixing plug 608. Two through holes 6011 corresponding to the sample insertion tube 504 are provided on the side of the box 601 facing the sample insertion tube 504, so that the iron column sample 609 can pass through the through holes 6011 and enter the opening of the sample insertion tube 504. A telescopic driving member 613 is fixed to the outer surface of the box 601 on the opposite side of the through hole 6011, and a strip 614 is connected to the movable end of the telescopic driving member 613, and then a top rod 6141 extending into the box 601 and in the same straight line as the through hole 6011 is connected to the upper and lower ends of the strip 614. Finally, a transparent observation port 615 is provided on the side of the box 601 above the two through holes 6011, and a sample replacement port 616 is provided on the side of the box 601 on the opposite side of the transparent observation port 615.

[0027] During the operation of the rust remover online sampling and detection device disclosed in this embodiment 1, the iron column samples with rusty surfaces and the iron column samples with smooth surfaces 609 are first inserted into the sample fixing insert 608 in an alternating manner one by one, and are fixed by tightening the fasteners 610.

[0028] During the process of stirring and preparing the rust remover in the reactor 2, the sampling pump 4 is started, and a certain amount of rust remover sample liquid is quantitatively extracted into the detection sample tube 5 through the sampling tube 3, and the lower end of the detection sample tube 5 is closed by the solenoid valve 503, so that the rust remover sample liquid is located in the upper detection tube 501. At this time, the pH value detection sensor 507 and the viscosity detection sensor 508 are used to perform online detection of the pH value and viscosity of the rust remover, and the feedback is sent to the control box 7.

[0029] In addition, the servo motor 603 is started to move the transmission belt 604, thereby moving a group of iron column samples 609 with rusty and smooth surfaces to align with the through hole 6011. After alignment, the telescopic drive member 613 is controlled to retract. Under the retraction action of the telescopic drive member 613, the two push rods 6141 extend into the interior of the box body 601 and push the upper and lower sample fixing plug-ins 608, so that the iron column samples 609 on the two sample fixing plug-ins 608 extend out of the corresponding through holes 6011 and enter into the openings of the upper and lower sample insertion tubes 504 respectively, and under their push, the blocking column 506 in the sample insertion tube 504 enters its inner end, and at the same time, the iron column sample 609 crosses the internal flow channel of the upper detection tube 501, so that the rust remover sample liquid in the upper detection tube 501 contacts the iron column sample 609. After the two iron column samples 609 react with the rust remover sample liquid for a period of time, the telescopic driving member 613 is controlled to extend to pull out and reset the iron column sample 609, and at the same time, the blocking column 506 again blocks the open end of the sample insertion tube 504. Finally, the servo motor 603 is started to transport the iron column sample 609 that has just reacted to the corresponding transparent observation port 615. The operator then uses the transparent observation port 615 to judge the rust removal of the iron column sample 609 with rust on the surface, and the corrosion of the iron column sample 609 with a smooth surface, and then judges the quality of the rust remover based on the pH value and viscosity measured online. Example 2

[0030] Example 2 discloses an online sampling and detection device for rust remover that is further improved and designed based on the technical solution in Example 1, and the similarities between it and Example 1 are not described again.

[0031] Reference Figure 5 and attached Figure 6In this embodiment 2, a bracket 617 is fixedly connected to the upper end of the side of the box body 601, and then two cameras 618 arranged at an interval up and down are installed on the bracket 617, and the two cameras 618 are set toward the transparent observation port 615. The camera 618 is used to replace manual labor to take independent photos of the two iron column samples 609 after the reaction, and then the photos are fed back to the control box 7 for comparison, so as to judge the rust removal effect of the rust remover sample liquid on the rust on the surface of the iron column sample 609 and the corrosion condition of the smooth iron column sample 609 surface, and finally the quality of the rust remover liquid is judged by combining the pH value and viscosity detected online, so that the entire rust remover online sampling and detection device realizes full automation processing, and only needs to manually replace the new iron column sample 609 through the sample replacement port 616 regularly.
