Description

Technical Field

[0001] The utility model relates to the technical field of sampling detection, in particular to a sampling detection device for polyurethane production. Background Art

[0002] Polyurethane is a polymer material that is widely used in daily life, such as paints and coatings in furniture, refrigerators and freezers in household appliances, roof waterproofing and insulation layers and interior and exterior coatings in the construction industry. It can also be made into various polyurethane materials. Existing polyurethane production equipment has inaccurate feeding, slow heating and cooling speeds, a long production cycle, and high production costs. Polyurethane resin is generally formed by the reaction of polyisocyanates with polyols and other substances containing active hydrogen atoms and groups. The reaction between the two is a reaction between solutions. Whether the reactor can be fully stirred and evenly mixed has a great influence on the degree of reaction.

[0003] As shown in the announcement number CN 215262644 U, a sampling and testing device for polyurethane production is disclosed, including a sampler, a sampling port, a shell and a body. The shell is placed on the front of the body, and fixing grooves are arranged on both sides of the outer side of the shell, and six fixing grooves are arranged on the outer side of the shell. Slide grooves are arranged on both sides of the outer side of the body. The device does not contain an automatic pressing and ejecting functional device inside, so it is laborious and time-consuming for the operator to take the sample tube, and the sample tube cannot be ejected. This makes it impossible for the operator to directly cooperate with the detector to complete the inspection of the polyurethane, and the quality and speed cannot be guaranteed. In addition, it does not have an integrated detection mechanism, resulting in low practical value. Utility Model Content
