[0002] A fixed-bed catalytic reactor is a stationary solid particle bed formed by filling a section of catalyst particles in a tubular reactor. The gaseous reactants flow through the gaps between the catalyst particles and undergo chemical reactions on the catalyst surface. According to the structural characteristics of the reactor, it can be divided into kettle type, tubular type, tower type, fixed-bed type and fluidized bed type reactors. Fixed-bed catalytic reactors are widely used reaction equipment in the chemical and petrochemical industries. According to their heat exchange methods, they can be divided into adiabatic and non-adiabatic (shell-and-tube type). Among them, the shell-and-tube fixed-bed reactor, the shell-and-tube diameter and length are important parameters that affect the performance and reaction efficiency of the shell-and-tube reactor. It is very necessary to measure and inspect the shell-and-tube length during the processing and production process.
[0003] In the prior art, it is generally necessary to move the laser rangefinder to the two ends of the tube array to measure the length. In this way, the movement of the laser rangefinder is more or less likely to affect the measurement accuracy, and it also needs to be slightly adjusted, which is more troublesome and thus affects the measurement efficiency. Utility Model Content

[0005] The utility model is implemented as follows: a dimension measuring instrument based on fixed bed reactor processing comprises a measuring platform and a laser rangefinder body, a telescopic cylinder is fixedly mounted on the outer wall in front of the measuring platform, the output end of the telescopic cylinder penetrates into the interior of the measuring platform and is fixedly connected with a push plate, the upper end of the push plate is fixedly connected with a baffle, a positioning cylinder is threadedly connected to the outer wall behind the measuring platform, a positioning plate is arranged inside the measuring platform corresponding to the positioning cylinder, the push plate and the positioning plate are arranged correspondingly, a laser rangefinder body is mounted on the measuring platform corresponding to the positioning cylinder, the probe of the laser rangefinder body corresponds to the baffle, a guide plate is slidably connected to the top of the measuring platform, and the guide plate is pressed against one side of the push plate.
[0006] Preferably, a guiding channel is opened on one side of the measuring platform, and the top end of the measuring platform corresponding to the guiding channel is arranged in an inclined structure, and the guiding channel is arranged corresponding to the guiding plate.
[0007] With this arrangement, when in use, after measuring the length of the tube array of the fixed bed reactor, when the tube array is pushed for unloading through the guide plate, the tube array will be discharged along the guide channel. The setting of the measuring table with an inclined part facilitates faster unloading of the tube array, which in turn facilitates the next measurement work and helps to improve the efficiency of the measurement work.
[0008] Preferably, a slide groove is provided on the top of the measuring platform, a second spring is fixedly connected to the slide groove, a slider is fixedly connected to the bottom of the guide plate, and the slider is fixedly connected to the end of the second spring and slides along the slide groove.
[0009] With this arrangement, when in use, the stability of the connection structure between the guide plate and the measuring table is effectively improved through the arrangement of the slide groove, the slider and the second spring. When unloading is carried out after the tube array is measured, the telescopic cylinder drives the push plate to move back and reset, and at the same time makes the push plate press against the guide plate and slide along it, that is, drives the slider at the bottom of the guide plate to move along the slide groove and squeeze the second spring, until the push plate first separates from the tube array of the fixed bed reactor and then separates from the guide plate. At this moment, the second spring drives the slider to slide and reset along the slide groove, which can drive the guide plate to reset and move and push the tube array, thereby facilitating faster unloading of the tube array and facilitating the next measurement work.
[0010] Preferably, an arc-guiding block is fixedly connected to the side wall of the push plate, and the arc-guiding block is pressed against the inner side of the guide plate.
[0011] With this arrangement, when in use, the arc guide block facilitates the push plate to move against the guide plate.

[0013] With this arrangement, it is convenient to install the laser rangefinder body during use. When measuring the tube array of the fixed bed reactor, the tube array is placed between the positioning plate and the push plate, and the telescopic cylinder is started to push the tube array. The tube array will drive the positioning plate to slide along the slide until the positioning plate is elastically contracted by the squeeze and fits to the inner wall of the measuring table. At this time, the horizontal plane of the inner surface of the positioning plate is flush with the probe of the laser rangefinder body, which is the starting position of the laser beam. When the laser rangefinder is started again, the laser beam will be projected onto the baffle on the push plate, which is the end position of the laser beam. The display screen on the laser rangefinder body can display the length of the tube array through the end position of the retroreflection point. The push plate and the positioning plate are pressed against the tube array to measure the length of the tube array. Accurate measurement can be performed without moving the laser rangefinder body, which effectively improves the measurement efficiency.
[0014] Preferably, a first spring is provided inside the positioning cylinder, one end of the first spring is connected to the bottom of the positioning cylinder, and the other end of the first spring is fixedly connected to a positioning plate. Two sliding plates are fixedly connected to the inner wall of the measuring platform, and both ends of the positioning plate are inserted into the sliding plates and are slidably connected to the sliding plates.
[0015] With this arrangement, when in use, the stability of the connection structure between the positioning plate and the measuring platform is effectively improved through the positioning tube and the first spring. When performing measurement work, it is convenient for the push plate to push the tube array and press it against the positioning plate to perform measurement work. The stability of the sliding movement of the positioning plate is ensured by the sliding sheet, so that it is not easy to deviate when moving, thereby facilitating the accuracy of measurement.
[0016] Preferably, a limiting clamping protrusion is fixedly connected to the surface of the push plate.
[0017] With this arrangement, when in use, the limiting clamping protrusion facilitates the tube array to be firmly clamped to the push plate, so that the push plate has high stability when driving the tube array to move, and effectively maintains accurate positioning during measurement.
[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0019] Through the cooperation of the limit clamp, the positioning plate, the slide, the first spring and the positioning cylinder, the tube array can be firmly pressed between the push plate and the positioning plate. When the push plate pushes the positioning plate to the inner wall of the measuring table, the laser rangefinder body can perform accurate measurement work, and accurate measurement work can be achieved without moving the laser rangefinder.
[0020] And, after the measurement work is completed, the push plate moves back to drive the array tubes to separate from the positioning plate, so that the first spring is reset and extends out of the guide cylinder, and then drives the positioning to slide and reset along the slide, and the push plate is pressed against the guide plate and moves back until the array tubes are separated from the positioning plate and the push plate in turn, and the push plate continues to move back until it is separated from the guide plate. At this time, the guide plate is reset under the action of the second spring, the slide groove and the slider, and at the same time, the array tubes whose measurement is completed are pushed, and the array tubes are discharged from the measuring table along the guide channel, which is convenient and fast for the next round of measurement work, and the material unloading is convenient and fast, which is conducive to further improving the measurement efficiency.

[0029] The above solution is adopted: a guide channel 2 is opened on one side of the measuring platform 1, and the top end of the measuring platform 1 corresponding to the guide channel 2 is arranged in an inclined structure, and the guide channel 2 is arranged corresponding to the guide plate 7.
[0030] During use, after measuring the length of the tube array of the fixed bed reactor, the tube array is pushed for unloading through the guide plate 7. At this time, the tube array will be discharged along the guide channel 2. The setting of the measuring platform 1 with an inclined part facilitates faster unloading of the tube array, which in turn facilitates the next measurement work and helps to improve the efficiency of the measurement work.
[0031] The above scheme is adopted: a slide groove 8 is opened on the top of the measuring platform 1, and a second spring 18 is fixedly connected to the slide groove 8. A slider 16 is fixedly connected to the bottom of the guide plate 7. The slider 16 is fixedly connected to the end of the second spring 18 and slides along the slide groove 8.
[0032] During use, the stability of the connection structure between the guide plate 7 and the measuring platform 1 is effectively improved by the arrangement of the slide groove 8, the slider 16 and the second spring 18.

The display screen on the laser rangefinder body 13 can display the length of the tube array through the end position of the retroreflection point. The push plate 3 and the positioning plate 10 are pressed against the tube array to measure the length of the tube array. Accurate measurement can be performed without moving the laser rangefinder body 13, which effectively improves the measurement efficiency.

When performing measurement work, the push plate 3 is convenient for pushing the tube array and pressing it against the positioning plate 10 to perform measurement work. The stability of the sliding movement of the positioning plate 10 is ensured by the slide 9, so that it is not easy to deviate when moving, thereby facilitating the accuracy of the measurement.
