Description

Technical Field

[0001] The utility model relates to the technical field of disinfectant production, in particular to a disinfectant production sampling and detection device. Background Art

[0002] In the production of disinfectants, it is necessary to sample the disinfectants to facilitate quality inspection of the produced disinfectants, which requires the use of sampling and detection devices.

[0003] During the production process of disinfectant, since solutions at different heights may have differences in concentration, composition or other properties, it is necessary to take samples at different heights and test the samples to ensure the representativeness and accuracy of the samples taken.

[0004] In the existing sampling process, most of the samples are taken directly from the disinfectant container or the disinfectant on the production line using a sampler, or the disinfectant container is sampled at different heights through a lifting function. This method requires reciprocating height adjustment, and the disinfectant cannot be sampled at multiple different positions at the same time. Reciprocating sampling causes the liquid in the sampling tube to mix, making it difficult to ensure the representativeness and accuracy of the sample. Utility Model Content

[0005] The embodiment of the utility model provides a disinfectant production sampling and detection device to solve the above-mentioned technical problems.

[0006] The embodiment of the utility model adopts the following technical scheme: it includes a cylinder, on which is provided a suction assembly capable of generating negative pressure inside the cylinder, on which is provided a plurality of sampling tubes connected with the interior of the cylinder, and the ends of the plurality of sampling tubes away from the cylinder are at different height positions, and when the suction assembly generates negative pressure on the interior of the cylinder, the plurality of sampling tubes connected with the interior of the cylinder generate negative pressure synchronously.

[0007] Furthermore, the connection positions of the plurality of sampling tubes and the cylinder are at the same height, and the plurality of sampling tubes extend to different lengths in the vertical direction.

[0008] Furthermore, the plurality of sampling tubes are made of flexible material, the lower portion of the cylinder is connected to a rod body, and the rod body is respectively locked with the water inlet ends of the sampling tubes through a plurality of fixing parts.

[0009] Furthermore, the fixing member is a rubber member, which is provided with a first through hole for the water inlet end of the sampling tube to pass through and a second through hole for the rod body to pass through, the diameter of the first through hole is smaller than the diameter of the water inlet end of the sampling tube, and the diameter of the second through hole is smaller than the diameter of the rod body.

[0010] Furthermore, the suction assembly includes a piston movably connected to the inside of the cylinder and a pulling rod connected to the upper part of the piston.

[0011] Furthermore, the surface of the rod body is provided with scale lines extending in a vertical direction.

[0012] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0013] In the utility model, the water inlet ends of multiple sampling tubes are placed at different heights in the disinfectant container to sample disinfectant liquids at different heights. When the suction component is used to suck the interior of the cylinder to generate negative pressure, multiple sampling tubes connected to the interior of the cylinder simultaneously generate negative pressure, and then the disinfectant liquid is sucked into the sampling tubes to form a certain liquid column, thereby completing the sampling of the disinfectant liquid at different vertical depths. Compared with the existing sampling device, the effect of this solution is that sampling at different heights can be completed at one time, and sampling is more convenient.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] After the disinfectant has been stationary for a period of time, the content of effective active ingredients in it is different at different heights. In order to study the content of effective active ingredients in the solution at each height after the disinfectant has been stationary, it is necessary to sample the disinfectant at different heights. In the existing sampling process, most of them use a sampler (such as a rubber-tipped dropper) to directly sample at different heights from the disinfectant container multiple times, or use a lifting function to sample at different heights of the disinfectant container. This method requires reciprocating height adjustment, and the disinfectant cannot be sampled at multiple different positions at the same time. Here, the utility model proposes a new disinfectant production sampling and detection device, which can sample disinfectant liquid at different vertical depths at the same time.

[0025] The embodiment of the utility model provides a disinfectant production sampling and detection device, comprising a barrel 1, on which a suction assembly capable of generating negative pressure inside the barrel 1 is provided, and on which a plurality of sampling tubes 12 connected with the inside of the barrel 1 are provided, and the ends of the plurality of sampling tubes 12 away from the barrel 1 are at different height positions, when the suction assembly generates negative pressure on the inside of the barrel 1, the plurality of sampling tubes 12 connected with the inside of the barrel 1 synchronously generate negative pressure, and when samples in different height areas need to be collected, since the ends of the plurality of sampling tubes 12 away from the barrel 1 are at different height positions in a disinfectant container 13, when the suction assembly sucks the inside of the barrel 1, negative pressure is generated on the inside of the barrel 1, and the synchronous sampling tubes 12 also generate negative pressure, and under the action of the negative pressure, the disinfectant in the disinfectant container 13 enters the inside of the sampling tube 12, and a certain liquid column is formed in the sampling tube 12 (the liquid does not enter the inside of the barrel 1 to avoid liquid mixing), and at this time, sampling of the disinfectant at different heights is completed, thereby improving the representativeness and accuracy of the sample taken.

[0026] Preferably, the utility model provides two implementation modes, the first implementation mode is as follows: Figure 1As shown, the connection positions of the multiple sampling tubes 12 and the barrel 1 are at the same height, and the multiple sampling tubes 12 extend in the vertical direction to different lengths. When the device is inserted into the disinfectant liquid, because the connection positions of the multiple sampling tubes 12 and the barrel 1 are at the same height and extend in the vertical direction to different lengths, the water inlet ends of the sampling tubes 12 are at different height positions, and the disinfectant liquid at different height positions can be sampled during sampling.

[0027] Preferably, the second embodiment is as follows Figure 3 As shown, multiple sampling tubes 12 are made of flexible material, and the lower part of the cylinder 1 is connected to a rod body 3. The rod body 3 is locked with the water inlet ends of the sampling tubes 12 through multiple fixings. The lengths of the multiple sampling tubes 12 are approximately equal. The rod body 3 and the sampling tubes 12 are relatively locked by the fixings. At this time, the water inlet ends of the sampling tubes 12 are at different heights. When facing sampling requirements at different positions, the fixings are moved to the relative height area. At this time, the water inlet ends of the sampling tubes 12 are at the corresponding height, and the disinfectant liquids at different heights are sampled at the same time.

[0028] In the above two embodiments, sampling at different heights can be completed in a single time, and the advantage of the first embodiment over the second embodiment is its simple structure, but compared with the second embodiment, since the water inlet end of the sampling tube 12 cannot be adjusted in height, it can only perform sampling at specific different heights. The disadvantage of the second embodiment over the first embodiment is that the structure is more complicated, but since the height of the water inlet end of the sampling tube 12 can be adjusted, it has better applicability and can be adjusted according to the required sampling height.

[0029] Preferably, the fixing member is a rubber member 4, which may also be a rope or a clamp, etc., for the purpose of relative locking between the water-entering end of the sampling tube 12 and the rod body 3. The rubber member 4 is provided with a first through hole 41 through which the water-entering end of the sampling tube 12 can pass, and a second through hole 42 through which the rod body 3 can pass. The diameter of the first through hole 41 is smaller than the diameter of the water-entering end of the sampling tube 12, and the diameter of the second through hole 42 is smaller than the diameter of the rod body 3. Since the diameter of the first through hole 41 is smaller than the diameter of the water-entering end of the sampling tube 12, and the diameter of the second through hole 42 is smaller than the diameter of the rod body 3, when the sampling tube 12 is inserted into the first through hole 41, the rubber member 4 will be deformed, exerting pressure on the outer wall of the sampling tube 12. The applied pressure generates friction between the sampling tube 12 and the rubber member 4, and the friction can maintain the relative stability of the positions of the sampling tube 12 and the rubber member 4. Similarly, there is friction between the rubber member 4 and the rod body 3 to ensure that the positions of the rod body 3 and the rubber member 4 are relatively stable. Considering that the sampling tube 12 and the rod body 3 are convenient for correspondingly inserting into the first through hole 41 and the second through hole 42, and when external force is applied, it is convenient to overcome the friction between the rod body 3 and the rubber member 4 so that the height position of the sampling tube 12 changes, the diameter of the first through hole 41 is set to be slightly smaller than the diameter of the water inlet end of the sampling tube 12, and the diameter of the second through hole 42 is set to be slightly smaller than the diameter of the rod body 3.

[0030] Preferably, the suction assembly includes a piston 5 movably connected to the inside of the cylinder 1 and a pull-out rod 6 connected to the upper part of the piston 5. Pulling the pull-out rod 6 drives the piston 5 to move upward, so that negative pressure is generated inside the cylinder 1 and the sampling tube 12 simultaneously generates negative pressure, and then the disinfectant liquid is sucked into the sampling tube 12. Although the above-mentioned method of using the piston 5 and the pull-out rod 6 to form a suction assembly can generate negative pressure inside the cylinder 1, the actual production process is not limited to this implementation method of the suction assembly. For example, a hollow rubber head (not shown in the figure) is installed on the top of the cylinder 1, and a structure similar to a rubber-headed dropper is formed between the cylinder 1 and the hollow rubber head. During the sampling process, negative pressure can also be generated inside the cylinder 1 by the hollow rubber head recovering its deformation after being pressed. Therefore, the implementation method of the suction assembly should be based on the ability to generate negative pressure inside the cylinder 1.

[0031] Preferably, the surface of the rod body 3 is provided with scale lines 7 extending in the vertical direction. According to the required sampling height, the fixing member can be moved to the position corresponding to the scale lines 7 through the scale lines 7, so that the staff can observe the height conveniently.

[0032] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
