Technical Field

The utility model relates to a sampler, concretely relates to vacuum sampler belongs to chemical industry equipment technical field.

Background

Original sample need be uncapped with reation kettle and take a sample, lead to the cauldron internal raw materials to leak, the workman inhales, harmful health. High-concentration raw material gas in the reaction kettle is dissipated in the air to pollute the atmosphere. Raw materials leak, wasting the cost. The reaction kettle is opened to take a sample, and outside air enters the kettle to destroy the vacuum environment in the kettle and pollute raw materials, so that a new scheme is urgently needed to solve the technical problem.

Disclosure of Invention

The utility model discloses just to the problem that exists among the prior art, provide a vacuum sampler, this technical scheme structural design is compact ingenious, use simple to operate, and the closed vacuum sampler of this scheme uses nitrogen protection, and the raw materials can not leak, can not cause the injury to workman's health to can not cause the cost extravagant.

In order to realize the above-mentioned purpose, the technical scheme of the utility model as follows, a vacuum sampler, the sampler includes head, head mouthpiece, valve one, valve two, sampling tube, viewport takeover, sight glass, pivot lid, valve three, quick detach blind plate, sample connection, valve four, intake pipe and sampling subassembly, reation kettle top head links to each other with the intake pipe, and installation valve one in the intake pipe, valve one upper and lower respectively set up the flange, set up two valve two on the valve one, and the left end is the nitrogen gas import, and the right-hand member is the evacuation mouth, and the intake pipe passes through the flange to be connected with the sampling tube, and the sampling tube both sides set up sealed flange, and the left side is connected with the sight glass through the viewport, and the takeover is established on the right side, seals with the quick detach blind plate, and the sampling tube top is connected with the pivot lid, and sampling subassembly is fixed in the pivot.

As an improvement of the utility model, the sampling subassembly includes sampling bottle, rope, handle, bearing one, axle, pulley and bearing two, the both ends of axle are provided with bearing one and bearing two respectively, and the one end at the bearing is fixed to the handle, and the sampler is connected through the rope to the pulley.

As an improvement of the utility model, the sampling tube is filled with nitrogen. Other gases in the replacement kettle can not enter the materials in the oxidation kettle during sampling. When other gases are replaced, the pressure in the kettle changes, and nitrogen is filled to ensure the pressure balance in the kettle; the nitrogen has stable chemical property and can not react with the materials in the kettle.

Compared with the prior art, the utility model has the advantages that 1) the whole structure of the technical proposal is designed compactly and skillfully, the utility model is a closed vacuum sampler, and the raw material can not leak under the protection of nitrogen, thereby not causing damage to the body of workers and wasting the cost; the vacuum environment in the kettle is ensured, nitrogen gas replacement is not needed, and the nitrogen gas consumption and the operation time of workers are saved; 2) this whole sealed operation of reation kettle sample, high concentration raw materials waste gas can not the loss in the air in the cauldron, can not cause the pollution to the environment.
