Technical Field

The utility model relates to a sampling technical field especially relates to a pipeline defective material collection structure.

Background

In the industries of food, medicine, chemical industry and the like, in order to detect whether each index of a produced product is qualified, a substance to be detected is often required to be sampled. After normal sampling operation is finished, some chemical substances in the sampling pipeline cannot flow out or be discharged in time. Residual materials which cannot be discharged completely on the pipeline can be slowly dripped into the field environment, so that material waste is caused; in addition, if the sampling valve is not closed in place, the material can also leak out of the sampling valve.

In the prior art, a containing structure is usually placed at the output end of a sampling pipeline to collect residual materials remained in the sampling pipeline. However, in the collecting process, because the closed collection cannot be performed, some volatile organic compounds (such as benzene, toluene, xylene, and the like) often overflow and are emitted, which not only seriously threatens the physical and mental health of the operators, but also may cause safety accidents.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The technical solution of the present invention is further explained by the specific embodiments with reference to the drawings.

The embodiment provides a pipeline defective material collecting structure, which is mainly used for the sampling test of the industries such as chemical engineering, medicine and the like and is used for sealing the tail end of a sampling pipeline. As shown in fig. 1, an input end of the sampling pipeline 4 is generally connected with a reaction kettle (not shown in the figure), a delivery end of the sampling pipeline 4 is connected with a sampler (not shown in the figure), and a sampling valve 3 is arranged on the sampling pipeline 4. During operation, the sampling valve 3 is opened, materials in the reaction kettle are conveyed to the sampler for detection, and after the detection is completed, the sampling valve 3 is closed.

Before improvement is not made, the conveying end of the sampling pipeline 4 is emptied after sampling is finished, so that some chemical substances in the sampling pipeline 4 cannot flow out or be drained in time. Residual materials on the pipeline can slowly drip into the field environment, so that material waste is caused. In addition, if the sampling valve 3 is not closed in place, the leakage of the materials from the sampling valve 3 can be caused, which not only seriously threatens the physical and psychological health of the operators, but also possibly causes safety accidents.

In order to overcome the above defects, the present embodiment adds the collector 1 and the collecting cover 2. Specifically, as shown in fig. 1, a through hole is formed in the top end of the collecting cover 2, a thread (not shown in the figure) is arranged on the inner wall of the collecting cover 2, and the collecting cover 2 is welded on the sampling pipeline 4 after being sleeved on the sampling pipeline 4 and having a certain distance from the conveying end. The collector 1 comprises a fixing part 11 and a containing part 12 which are connected and communicated in sequence, the outer surface of the fixing part 11 is provided with a thread (not shown in the figure) matched with the internal thread of the collecting cover 2, and the sampling pipeline 4 can extend into the fixing part 11. After the sampling is completed, the collector 1 is sleeved on the conveying end of the sampling pipeline 4, and then the fixing part 11 is in threaded connection with the collecting cover 2, so that the collection of residual materials in the sampling pipeline 4 can be realized.

It should be noted that the inner diameter of the fixing portion 11 is 0.3 to 0.5mm larger than the outer diameter of the sampling pipeline 4, so that on one hand, the fixing portion 11 can easily cover the conveying end of the sampling pipeline 4, and on the other hand, a small gap is kept between the outer wall of the sampling pipeline 4 and the inner wall of the fixing portion 11, thereby reducing the possibility of the volatile organic compound in the material overflowing; in addition, in order to ensure the tightness of the collector 1 itself, the fixing portion 11 is integrally injection-molded with the housing portion 12.

Optionally, a sealing ring (not shown in the figures) is further arranged inside the collection cover 2, and after the fixing part 11 is connected with the collection cover 2 by threads, the top end of the fixing part 11 just abuts against the sealing ring, so that the sealing collection of the whole structure is ensured, and the volatile compound is prevented from overflowing and scattering; in addition, fixed part 11 and collection cover 2 threaded connection back, the length of stretching into of sampling pipeline 4 is one fifth of the degree of depth of collector 1 exactly, can collect the residual material in the sampling pipeline 4, can avoid the delivery end of sampling pipeline 4 to soak in the residual material again, however in other embodiments, the length of stretching into of sampling pipeline 4 can be a little longer.

Further, in the pipeline residual material collecting structure provided by the embodiment, the collecting cover 2 is a stainless steel part, so that the strength is ensured, and the pipeline residual material collecting structure is corrosion-resistant; the collector 1 is a plastic piece, is light in weight and does not add excessive weight to the sampling pipeline 4. Of course, in other embodiments, the collection hood 2 and the collector 1 may be made of other suitable materials, and are not limited to stainless steel and plastic.

It should be noted that, in general, the residual material in the sampling pipeline 4 is not too much, and the residual material in the collector 1 can be directly disposed of as a dangerous material, so as to prevent the harm to workers or the occurrence of safety accidents.

The pipeline defective material collection structure that this embodiment provided sets up on sampling pipeline 4 and collects cover 2, sets up simultaneously can with collect 2 threaded connection's of cover collector 1, and the during operation is unscrewed collector 1, normally carries out the sampling operation, finishes the back with collector 1 again and collects 2 threaded connection of cover after the operation. Above setting can effectually avoid the interior residual material's of sampling pipeline 4 hourglass outward, reduces the impact to the environment, and can avoid the volatile compound loss in the material to come out, is favorable to guaranteeing operating personnel's physical and mental health. In addition, the arrangement of the sealing ring can also prevent the volatile compound from overflowing and scattering.
