Description

Technical Field

[0001] The utility model relates to the technical field of cross-linking agent production, in particular to an automatic sampling device for a reaction kettle used in cross-linking agent production. Background Art

[0002] Crosslinkers, also known as bridging agents, curing agents, hardeners, or curing agents, are a crucial component of polyolefin photoresists and a key chemical in the field of polymer materials. They are widely used in a variety of industries, including rubber, plastics, coatings, adhesives, and medical aesthetics. In the rubber industry, crosslinkers (often called vulcanizers) are a key raw material for the preparation of rubber products. In the plastics industry, crosslinkers are used to improve the strength, heat resistance, and wear resistance of plastics. Reactors are a common type of reaction equipment used in production. Through the structural design and parameter configuration of the vessel, they achieve the heating, evaporation, cooling, and low-speed mixing functions required by the process.

[0003] Existing reactors have low sampling efficiency and poor accuracy when sampling, and are not easy to adjust the height according to different reactors, which makes sampling and installation inconvenient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic sampling device for a reactor used in cross-linking agent production is proposed, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic sampling device for a reactor used in cross-linking agent production, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic sampling device for a reactor for cross-linking agent production, comprising a control box and a sampling tube, a connecting pad is installed on the top of the control box, and a sampling pump is mounted on the top of the connecting pad, the inlet and outlet ports of the sampling pump are provided with a liquid guide tube, and the liquid outlet end of the liquid guide tube is provided with a discharge guide plate, and the liquid inlet end of the liquid guide tube is provided with a sampling tube, one end of the inner part of the liquid guide tube is connected with a sampling valve, and the bottom of the sampling tube is connected with an anti-blocking joint, a slide rail slider assembly is provided on the inner side of the control box, a limiting plate is installed on the horizontal end of the connecting pad, and an extension arc plate is provided on the other side of the limiting plate, a lifting rod is vertically provided on the bottom of the connecting pad, and a slide plate is installed on the bottom of the lifting rod, and the slide plate and the slide rail slider assembly are detachably fixedly connected, and a sampling barrel is wrapped on the inner side of the limiting plate.

[0007] Furthermore, the upper and lower positions of the discharge ports of the sampling barrel and the discharge guide plate cooperate with each other.

[0008] Furthermore, threaded joints are provided at the upper and lower ends of the sampling tubes, and multiple groups of the sampling tubes can be threadably disassembled and installed.

[0009] Furthermore, the sampling tube, the liquid guiding tube and the anti-blocking joint are fixedly connected by threads.

[0010] Furthermore, the control box forms an up and down lifting structure between the slide rail and slider assembly and the slide, and the lifting rod and the slide form an up and down lifting structure.

[0011] Furthermore, the dimensions of the extended arc plate and the sampling barrel match each other.

[0012] The utility model provides an automatic sampling device for a reactor used in cross-linking agent production, which has the following beneficial effects:

[0013] 1. The sampling tube, the main component of the sampling device, is designed to be adjustable. One end of the sampling tube extends into the reactor and the other end is connected to the sampling valve. The sampling tube is made of corrosion-resistant and high-temperature resistant materials, such as stainless steel or Teflon, to ensure that it will not be affected by chemical corrosion or high temperatures during the crosslinker production process.

[0014] The threaded joint of the sampling tube can adjust the height according to the sampling requirements. On the other hand, when the thread is installed, the connection structure is relatively tight, and it is not easy to be corroded or deformed to cause leakage, thereby reducing the impact on the production of the cross-linking agent.

[0015] 2. In the present invention, the sampling valve is installed on the pipeline between the liquid guide tube and the sampling pump to control the sample flow during the sampling process; the sampling valve adopts a high-precision solenoid valve with the characteristics of fast response, high sealing and long life to ensure the accuracy and reliability of the sampling operation; the sampling pump is controlled by the control system to start and stop and the speed to adjust the sampling flow and speed.

[0016] 3.

In addition, a liftable slide is provided at the bottom of the sampling bucket, which can adapt to sampling buckets of different heights and meet the sampling requirements of different doses.

[0017] A limiting plate is provided on the outside of the connecting pad for support. The limiting plate utilizes the extended arc plate extending from the outside to limit and wrap the sampling barrel, thereby ensuring the overall stability of the sampling barrel.

[0025] The sampling tube 2, the main component of the sampling device, is adjustable, with one end extending into the reactor and the other connected to the sampling valve. The sampling tube is made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel or Teflon, to ensure it is not affected by chemical corrosion or high temperatures during the crosslinker production process.

[0026] The threaded joint 201 of the sampling tube 2 can adjust the height according to the sampling requirements. On the other hand, when the thread is installed, the connection structure is relatively tight and is not prone to corrosion, deformation and leakage, thereby reducing the impact on the production of the cross-linking agent.

[0027] The sampling valve 3 is installed on the pipeline between the liquid guide tube 4 and the sampling pump 6 to control the flow of samples during the sampling process. The sampling valve 3 adopts a high-precision solenoid valve with the characteristics of fast response, high sealing and long life to ensure the accuracy and reliability of the sampling operation.

[0031] Working principle: For this type of automatic sampling device for reactors used for cross-linking agent production, first, according to the sampling situation in the reactor, multiple groups of sampling tubes 2 are threadedly installed to adapt to the sampling requirements of the reactor. Then, the sampling tubes 2 and the anti-blocking joint 12 are inserted into the interior of the reactor. At the same time, the sampling barrel 11 is placed at the sampling position of the slide plate 10, and the extended arc plate 901 of the limit plate 9 is used to pre-position the sampling barrel 11. Then, the lifting rod 8 is controlled to drive the sampling barrel 11 to rise, so that the sampling port of the sampling barrel 11 corresponds to the discharge port of the discharge guide plate 7. Then, the sampling valve 3 at the top is controlled to open, so that the liquid collection channel of the liquid guide tube 4 is opened, and the sampling pump 6 of the power source of the sampling device is started. The reagent is sampled and extracted from the anti-blocking joint 12 end at the bottom, so that the reagent passes through the sampling tube 2, the liquid guide tube 4 and the discharge guide plate 7 and enters the sampling barrel 11 for storage.
