Abstract
The utility model discloses a device of convenient sample, sweep the pipe including sampling tube and nitrogen gas, the ejection of compact valve intercommunication of sampling tube one end and neutralization cauldron bottom is provided with sample valve on the sampling tube, nitrogen gas sweeps pipe and sampling tube other end intercommunication, is provided with on the nitrogen gas sweeps the pipe and sweeps the valve. The utility model discloses increase nitrogen gas at the sampling tube and sweep the pipeline after, realized safe quick sample, reduce material loss and material and shed the danger that brings, secondly the sampling point is not restricted to under the cauldron, and near extensible to feeding pipeline realizes convenient and fast sampling test.
Description
Technical Field
The utility model relates to a chemical industry equipment technical field, concretely relates to make things convenient for device of sample.
Background
When the neutralization kettle is used for acid-base neutralization, multiple sampling is needed to detect the pH value so as to control the feeding amount. The original sampling port is arranged at the bottom of the neutralization kettle, and when sampling is carried out, the sampling port of the kettle bottom valve needs to be drained and flushed for many times before sampling is carried out, so that material loss is easily caused, and the danger coefficient of personnel contact is increased; in addition, the feeding valve and the sampling point on the neutralization kettle are far away, and the neutralization kettle needs to go up and down floors, so that the operation is inconvenient.
Disclosure of Invention
The utility model discloses to the problem in the background art, designed a device of convenient sample, aim at convenient and fast sample, reduce the material loss, improve factor of safety.
In order to achieve the above object, the technical solution of the present invention is as follows:
the utility model provides a device of convenient sample, includes sampling tube and nitrogen gas purging pipe, the ejection of compact valve intercommunication of sampling tube one end and neutralization kettle bottom is provided with the sample valve on the sampling tube, nitrogen gas purging pipe and sampling tube other end intercommunication are provided with on the nitrogen gas purging pipe and sweep the valve.
Furthermore, the sampling tube is L-shaped, the bottom of the sampling tube is communicated with a discharge valve of the neutralization kettle, and the upper end of the sampling tube extends to the position near the feeding pipeline, so that the operation is convenient.
Preferably, the sampled valve is an electrically-operated regulating valve.
Preferably, the purge valve is an electrically-operated regulating valve.
Preferably, the sampling tube and the nitrogen purging tube are of an integrally formed structure.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses increase nitrogen gas at the sampling tube and sweep the pipeline after, realized safe quick sample, reduce material loss and material and shed the danger that brings, secondly the sampling point is not restricted to under the cauldron, and near extensible to feeding pipeline realizes convenient and fast sampling test.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the device comprises a neutralization kettle, 2, a purging valve, 3, a sampling valve, 4, a discharging valve, 5 and a nitrogen purging sampling pipe.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1, the utility model discloses a device of convenient sample, sweep sampling tube 5 including L type nitrogen gas, nitrogen gas sweeps 5 low sides of sampling tube and the 4 upper ends of ejection of compact valves of neutralization kettle 1 intercommunication, and top and nitrogen gas intercommunication let in nitrogen gas, are provided with on the sampling tube and sweep valve 2 and sample valve 3, and wherein sample valve 3 sets up and is sweeping 2 downside of valve.
And (3) a neutralization process, which needs to be carried out by sampling: closing a sampling valve, closing a discharge valve, slightly opening a purging valve, purging the materials in the sampling pipe to a neutralization kettle by nitrogen, closing the purging valve, and slightly opening the sampling valve for sampling detection. Therefore, the purpose of safe and rapid sampling is achieved, material loss and cost are reduced, the danger coefficient is reduced, and safe production is realized.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
