Description

Technical Field

[0001] The utility model relates to a chemical instrument experimental apparatus, in particular to a dust-proof and dust-removing strength measuring instrument. Background Art

[0002] Hydrogenation of waste lubricating oil requires a variety of catalysts, such as hydrofining catalysts, protective agents, etc. Strength measurement tests are used to evaluate the mechanical properties of catalysts such as compressive and tensile resistance. Because the reaction pressure of the waste lubricating oil hydrogenation unit is relatively high, the size of the catalyst's compressive and anti-crushing ability directly affects its durability and stability, thus affecting the operation of the waste lubricating oil hydrogenation unit. During the operation of the waste lubricating oil hydrogenation unit, factors such as thermal expansion, redox pollution, and carbon deposition may lead to a decrease in catalyst strength, resulting in a decline and failure of catalyst performance, affecting the operation of the unit equipment and thus the effect of waste lubricating oil recycling. Therefore, attention needs to be paid to the catalyst strength measurement data.

[0003] Currently, the strength measuring instruments on the market are all open-designed, with a large amount of dust, which is harmful to the respiratory system of R & D personnel. When measuring the crushing strength, large particle debris is easily ejected into the eyes of R & D personnel, posing a safety hazard. The variable ejection angle of the debris is not easy to clean, and repeated cleaning of debris is required for multiple measurements, reducing the work efficiency of R & D personnel. Therefore, it is necessary to develop a dust-proof and dust-removing strength measuring instrument to ensure the safety of R & D personnel, improve work efficiency, reduce time consumption, simplify processes, and be easy to use. Summary of the Invention

[0004] The purpose of the utility model is to provide a dust-proof and dust-removing strength measuring instrument that ensures the safety of R & D personnel, improves work efficiency, reduces time consumption, simplifies processes, and is easy to use.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] The dust-proof and dust-removing strength measuring instrument is composed of an instrument switch 1, an indicator light 2, a display screen 3, a control panel 4, a force-measuring pressure head 5, a force-measuring sample stage 6, a dust-proof cover 7, a dust-removing switch 8, a sealing hole 9, a dust-removing pipe 10, a dust collection tank 11, and a dust-removing suction head 12.

[0007] The dust-proof cover 7 is made of acrylic material that is lightweight, easy to observe experiments, and has weather resistance and chemical resistance. It is located around the force-measuring pressure head 5 and the force-measuring sample stage 6, and an 8-cm sample measurement opening is left on the front.

[0008] The dust collection tank 11 is connected to the dust-removing pipe 10, and the dust-removing pipe 10 is then connected to the dust-removing suction head 12 through the sealing hole 9.

[0009] The front end of the dust-removing pipe 10 connected to the dust-removing suction head 12 is made of telescopic plastic material, and the dust-removing suction head 12 can move through the dust-removing pipe 10.

[0010] The sealing hole 9 is located at the left rear position of the dust-proof cover 7, providing a channel for the dust removal pipe 10 while not affecting the strength measurement.

[0011] The dust removal switch 8 is located on the dust collection tank 11, and the suction force can be adjusted. The dust and debris are collected in the dust collection tank 11 and cleaned up regularly at one time.

[0012] When using the present utility model, first turn on the strength measuring instrument switch 1, and the indicator light 2 lights up. Place the catalyst on the force measuring sample table 6 through the force measuring port of the dust-proof cover. Operate the force measuring indenter 5 through the control panel 4 to measure the crushing strength of the catalyst. The dust and ejected debris flying instantly when the catalyst is crushed by the force measuring indenter 5 are blocked by the dust-proof cover 7 and concentrated near the force measuring sample table 6. Record the strength data on the display screen 3. After all the tests are completed, turn on the dust removal switch 8, and the suction force of the dust removal switch 8 can be adjusted according to the size of the debris. The debris is sucked into the dust collection tank 11 through the dust removal pipe 10 by the dust removal suction head 12. If there are dead corners where the debris cannot be cleaned, since the front section of the dust removal pipe 10 and the dust removal suction head 12 are telescopic parts, move the dust removal suction head 12 to clean it up. The dust collection tank 11 has a large capacity and can be cleaned regularly and centrally.

[0013] Compared with the open design of the conventional strength measuring instrument, the beneficial effects of the present utility model are as follows:

[0014] The present utility model develops a dust-proof and dust-removing strength measuring instrument. The dust-proof cover prevents the catalyst debris from being ejected during the force measurement process, concentrates the debris on the force measuring sample table, and is convenient for cleaning the debris; it can also prevent the debris from being ejected into the eyes of the R & D personnel when the crushing strength is too large.

[0015] Dust will be generated when the catalyst measures the crushing strength, and the dust-proof cover has a certain protective effect on the R & D personnel inhaling dust.

[0016] The length of the dust removal pipe can be adjusted telescopically, which can effectively prevent the debris from hiding in the dead corners of the strength measuring instrument and affecting its use; the suction force is adjusted through the switch of the dust collection tank, and debris of any size can be easily cleaned; the dust collection tank has a large capacity and can be cleaned regularly and centrally, saving time and effort.

[0017] The structure is simple and easy to use, and it can be widely applied to the evaluation and R & D field of catalysts. One-key dust-proof and dust-removing is convenient and fast, and centralized cleaning of chemical debris saves time and effort and is safer. Description of the Drawings
