Description

Technical Field

[0001] The utility model belongs to the technical field of refined sampling, and specifically relates to a refined sampling device. Background Technique

[0002] Chemical refined sampling usually refers to sampling raw materials, intermediate products or finished products during the chemical production process and conducting detailed analysis and testing. This sampling process is crucial for ensuring product quality, production process control, compliance with safety regulations, and R & D work;

[0003] The existing chemical refined sampling device samples chemical raw materials by having a staff member hold a sampling tube to suck the chemical raw materials during the production process. However, due to the way of holding the sampling tube and the fact that the chemical raw materials are in a liquid state, during the sampling of chemical raw materials, if the operation is improper, the chemical raw materials may contaminate the hand skin by splashing, thus causing personnel safety problems;

[0004] To solve the above problems, a refined sampling device is proposed in this application. Content of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art and provides a refined sampling device.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: a refined sampling device includes a sampling tube, and a sampling structure is arranged on the sampling tube;

[0007] A clamping structure is arranged on the sampling tube;

[0008] The sampling structure includes a communicating pipe communicated with the sampling tube. A piston is hermetically and slidably connected to the inner wall of the sampling tube. A core rod is installed on the side of the piston away from the communicating pipe. The bottom of the sampling tube is communicated with a discharge pipe, and a collecting tank is threadedly connected to the inner wall of the discharge pipe.

[0009] The core rod is located at the exact center position inside the sampling tube. A connecting plate is installed on the outer wall of the core rod, and the outer wall of the connecting plate is in contact with the inner wall of the sampling tube. By setting the connecting plate, the moving effect of the core rod is effectively improved.

[0010] One end of the core rod away from the piston is installed with a pressing hand. One end of the communicating pipe away from the sampling tube is communicated with a conical tube. By setting the pressing hand, it is convenient for personnel to pull the core rod.

[0011] The clamping structure includes a fixing plate installed on the bottom wall of the adjacent communicating pipe of the sampling pipe. A fixing block is installed on the outer wall of the sampling pipe, and the outer wall of the fixing block is fixedly connected to the outer wall of the fixing plate. One side of the fixing plate adjacent to the threaded rod is rotatably connected to a threaded rod, and a slide plate is threadedly connected to the outer wall of the threaded rod. The top wall of the slide plate is slidably connected to the outer wall of the fixing block. By setting the threaded rod and the slide plate, it is used to fix the sampling pipe.

[0012] One side of the fixing plate adjacent to the threaded rod is provided with a sliding rod, and the outer wall of the sliding rod is slidably connected to the inner wall of the slide plate. By setting the sliding rod, the moving effect of the slide plate is effectively improved.

[0013] A handle is installed at the bottom of the sampling pipe far from the communicating pipe. By setting the handle, it is convenient for personnel to operate the device.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By setting the sampling structure, after the staff threadedly connects the collection tank to the discharge pipe, then pulls the pressing hand to drive the piston to pull repeatedly, so that the liquid in the device during chemical production is sucked into the interior of the collection tank. Through the L shape provided, the angle and distance between the sample and the personnel are increased, effectively avoiding the problem of contaminating the hand skin and causing safety problems for the personnel.

[0016] 2. By setting the clamping structure, after placing the communicating pipe in the liquid, then fitting the fixing plate to the inner wall of the outer shell of the device during chemical production.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0026] In the description of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0027] In the description of the present application, the term "for example" is used to mean "serving as an example, illustration, or explanation". Any embodiment described as "for example" in the present application is not necessarily construed as being more preferred or having more advantages than other embodiments. In order for any person skilled in the art to implement and use the present invention, the following description is given. In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other instances, well - known structures and processes are not elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0028] Refer to Figures 1-3 , a refined sampling device, including a sampling tube 1, a sampling structure 2 is arranged on the sampling tube 1. The sampling structure 2 includes a connecting tube 201 connected to the sampling tube 1. The sampling tube 1 and the connecting tube 201 are in an L - shape. By placing the connecting tube 201 at a suitable position for sucking samples, a piston 202 is hermetically and slidably connected to the inner wall of the sampling tube 1. Multiple annular notches are formed on the piston 202. When the piston 202 moves, the annular notches can provide a certain buffer space and increase the toughness of the periphery of the piston 202, not only having a certain sealing property but also increasing its pressure, thereby improving the extraction effect.

[0029] On the side of the piston 202 away from the connecting pipe 201, a core rod 203 is installed. The bottom of the sampling pipe 1 is connected to a discharge pipe 204. The inner wall of the discharge pipe 204 is threadedly connected to a collection tank 205. The collection tank 205 is made of a transparent material for observing the sampling volume. By repeatedly pulling the core rod 203 and the piston 202, the sample is sucked into the sampling pipe 1 through the connecting pipe 201 and then flows into the collection tank 205 through the discharge pipe 204.

[0030] The core rod 203 is located at the exact center position inside the sampling pipe 1. A connecting plate 206 is installed on the outer wall of the core rod 203. The outer wall of the connecting plate 206 is in contact with the inner wall of the sampling pipe 1. There are six connecting plates 206, which are evenly distributed around the circumference of the core rod 203. When the core rod 203 is pulled, through the mutual friction between the connecting plate 206 and the inner wall of the sampling pipe 1, the stability of the core rod 203 during movement is effectively improved.

[0031] One end of the core rod 203 away from the piston 202 is installed with a pressing hand 207. The set pressing hand 207 facilitates the personnel to pull the core rod 203. One end of the connecting pipe 201 away from the sampling pipe 1 is connected to a conical pipe 208. The bottom wall of the conical pipe 208 is a small opening. Due to its gradually thickening shape, the connecting pipe 201 will experience complex resistance changes when entering the water. As the pipe body gradually penetrates into the water, the resistance it receives may change with the increase in the cross-sectional area. The resistance of the connecting pipe 201 when entering the water may generate additional dynamic effects due to the shape change, effectively increasing the pressure required for sampling.

[0032] Refer to Figure 2 and Figure 4 As shown in, a clamping structure 3 is provided on the sampling pipe 1. The clamping structure 3 includes a fixing plate 301 installed on the bottom wall of the sampling pipe 1 adjacent to the connecting pipe 201. The side of the fixing plate 301 away from the connecting pipe 201 is fitted to the inner wall of the outer shell of the device during chemical production. A fixing block 304 is installed on the outer wall of the sampling pipe 1. The outer wall of the fixing block 304 is fixedly connected to the outer wall of the fixing plate 301. The bottom wall of the fixing block 304 is fitted to the top wall of the outer shell of the device during chemical production.

[0033] One side of the fixing plate 301 adjacent to the threaded rod 303 is rotatably connected to a threaded rod 303. The outer wall of the threaded rod 303 is threadedly connected to a sliding plate 302. The top wall of the sliding plate 302 is slidably connected to the outer wall of the fixing block 304. By turning the threaded rod 303, the sliding plate 302 is driven to slide on the fixing block 304, so that the sliding plate 302 is closely attached to the outer shell of the device during chemical production, for a certain clamping of the device.

[0034] On one side of the fixed plate 301 adjacent to the threaded rod 303, a slide rod 305 is installed. The outer wall of the slide rod 305 is slidably connected to the inner wall of the slide plate 302. The slide rod 305 and the threaded rod 303 are on the same horizontal plane, and the threaded rod 303 and the slide rod 305 are symmetrically distributed with the fixed plate 301 as the center. By providing the slide plate 302, the deviation of the slide plate 302 during movement is further prevented.

[0035] A handle 4 is installed at the bottom of the sampling tube 1 away from the communicating tube 201. When operating the device, the staff can hold the handle 4 with one hand and pull the pressing hand 207 with the other hand, effectively improving the convenience of operating the device.

[0036] Working principle:

[0037] After placing the communicating tube 201 in the liquid, then attach one side of the fixed plate 301 to the inner wall of the housing of the device during chemical production. At this time, turn the threaded rod 303 to drive the slide plate 302 to move towards the fixed plate 301, so that the slide plate 302 and the fixed plate 301 are clamped with the housing of the device during chemical production, which not only effectively reduces the consumption of human physical strength, but also effectively improves the stability when sampling.

[0038] After the staff threadedly connects the collection tank 205 to the discharge pipe 204, then pull the pressing hand 207 to drive the core rod 203 and the piston 202 to pull repeatedly, so that the liquid in the device during chemical production is sucked into the conical tube 208, and then flows into the interior of the collection tank 205 through the communicating tube 201 and the sampling tube 1. When the sample volume in the collection tank 205 is appropriate, push the piston 202 to push the liquid out of the conical tube 208 again. By providing the L shape, the angle and distance between the sample and the staff are increased, effectively avoiding the problem of contaminating the hand skin and causing personal safety problems.

[0039] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
