Description

Fire retardant production sampling device

Technical Field

The invention belongs to the technical field of flame retardant production, and particularly relates to a flame retardant production sampling device.

Background

The reaction material in the polymerization reaction kettle needs to be sampled and tested at regular time during the production of the high molecular flame retardant, the indexes such as monomer reaction conversion rate, viscosity average molecular weight and viscosity of a test product are obtained, a sampler is needed during sampling, the existing sampling instrument is generally a negative pressure type sampler with a piston, liquid enters a sampling cylinder from an opening at the bottom of the sampling cylinder by extracting vacuum in the sampling cylinder, and the sample in the sampling cylinder is pushed out after the sample is taken out.

SUMMERY OF THE UTILITY MODEL

To above technical problem, the utility model aims to provide a fire retardant production sampling device.

Fire retardant production sampling device, include the sampler barrel and be located its inside vertical piston rod, the piston rod bottom is equipped with the piston, the welding of piston rod top has the handle, the welding has the semicircular backup pad on sampler barrel bottom opening part inner wall, the welding has the annular baffle of half circle on the sampler barrel inner wall with backup pad with horizontal position, form the liquid flow passageway between backup pad and the baffle, the backup pad upper surface is stained with circular shape sheet rubber, sheet rubber diameter equals with the sampler barrel internal diameter, be equipped with the lofting pipe with the inside intercommunication of sampler barrel on the shell of sampler barrel lower part, the lofting pipe opening part is equipped with the detachable and seals the cap.

The opening of the lofting pipe is provided with external threads, the sealing cap is provided with internal threads, and the sealing cap is screwed at the opening of the lofting pipe to seal the lofting pipe.

The thickness of the supporting plate is equal to that of the baffle plate.

Compared with the prior art, the utility model, following beneficial effect has.

The utility model discloses the backup pad plays the support fixed action to the sheet rubber, the sheet rubber covers and seals liquid flow channel on the semicircle ring baffle, during the sample, insert inside the reaction liquid with the sampler barrel bottom, upwards pull up the piston rod, because the flexible nature of sheet rubber, the sheet rubber kickup of liquid flow channel top under the negative pressure effect, the reaction liquid gets into in the sampler barrel through liquid flow channel, the sample finishes, no longer pull up the piston rod and form the negative pressure, the sheet rubber resilience resumes, form closed once more to liquid flow channel, prevent sample liquid and leak down, during the laying-out, only need open the closing cap, promote the piston rod downwards, with a section of thick bamboo interior sample through the laying-out pipe release can.

The utility model provides a technical problem that has the difficult technical problem that gets into introduction port and sample liquid and leak under the sampler barrel bottom liquid outlet because of liquid has viscosity during the sample among the prior art.
