Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, and particularly to a sampling device for a reaction kettle. Background Art
[0002] Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food. They are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation. For example, reactors, reaction pots, decomposition pots, polymerization kettles, etc. The materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. The products after the reaction in the reaction kettle are transported to a temporary storage warehouse through pipelines. Workers need to take samples in the pipeline section for product inspection. The existing sampling methods all set sampling pipelines in the product pipeline and set sampling valves on the sampling pipelines to achieve sampling of the liquid in the pipeline. In this way, after each production of the product, sampling personnel need to take samples on-site. In the production of products with short production times for multiple batches, sampling personnel need to continuously return to the site for sampling and need to wait for the sampling personnel to arrive at the site, which increases the workload of the sampling personnel and reduces the production efficiency. In addition, when using the method of setting sampling valves on the sampling pipelines, after each sampling, the remaining products in the previous sampling pipeline need to be discharged before sampling, and the discharged products are wasted, resulting in waste of materials and increased production costs.

The sampling pipeline is provided with a first solenoid valve. A second solenoid valve is arranged below the first solenoid valve. A return pipeline is connected between the main pipelines of the first solenoid valve and the second solenoid valve. The return pipeline is connected to the main pipeline. The return pipeline is provided with a pump. A slide rail is arranged above the base. A slide seat is arranged at the bottom of the movable seat. The slide rail is slidably connected to the slide seat. A ball screw nut seat is arranged at the bottom of the movable seat. A lead screw is arranged above the base through a bearing seat. The lead screw is in threaded connection with the ball screw nut seat. A motor is arranged on one side of the base. The motor is in transmission connection with the lead screw.
