Description

Technical Field

[0001] This utility model belongs to the field of material sampling technology, specifically relating to a telescopic granular material sampling device. Background Technology

[0002] Product sampling is essential in the production processes of many industries such as petroleum, chemical, pharmaceutical, grain, food, power, building materials, metallurgy and mining. Various sampling devices are important process equipment in systems engineering.

[0003] However, most existing sampling devices have complex structures, are prone to jamming during sampling, have poor sealing, and cause material leakage during sampling, leading to material contamination, batch scrapping, and economic losses. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by designing a telescopic granular material sampling device that is simple in structure, stable and reliable, and can effectively prevent the batch scrapping of materials and reduce economic losses.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a telescopic granular material sampling device, comprising an outer sampling tube connected at one end to an opening in the side wall of a silo, and an inner sampling tube fitted inside the outer sampling tube and capable of telescopic movement along the outer sampling tube under the action of a drive component. The inner sampling tube has an inlet at its front end and an outlet at its rear end corresponding to the outlet on the outer sampling tube. When the inner sampling tube extends forward, the inlet is connected to the inside of the silo, and the outlet is not connected to the outlet. When the inner sampling tube retracts backward, the inlet is not connected to the inside of the silo, and the outlet is connected to the outlet.

[0006] Preferably, the front end and rear end of the sampling inner tube are both closed structures, the inlet is located above the front side wall of the sampling inner tube, and the outlet is located below the rear side wall of the sampling inner tube.

[0007] Preferably, the sampling tube is inclinedly connected to the side wall of the silo.

[0008] Preferably, the discharge port is located below the sampling outer tube and is designed to be perpendicular to the horizontal plane.

[0009] Preferably, an isolation ring is provided between the outer sampling tube and the inner sampling tube.

[0010] Preferably, a positioning ring is provided between the front ends of the outer sampling tube and the inner sampling tube.

[0011] Preferably, the drive assembly includes a telescopic cylinder, and a filter pressure reducing valve and a manual control valve connected to the telescopic cylinder.

[0012] After adopting the above technical solution, the telescopic granular material sampling device provided by this utility model has the following beneficial effects:

[0013] This invention uses a manual control valve to control a telescopic cylinder to move the sampling inner tube forward, exposing the inlet in the hopper. Material flows into the sampling inner tube through the inlet and is stored. When the telescopic cylinder retracts, its rod pulls the sampling inner tube backward. The material stored in the sampling inner tube flows out through the outlet at the bottom of the sampling inner tube under the influence of gravity and exits from the outlet at the bottom of the sampling outer tube, thus completing the sampling process. This invention has a relatively simple structure and advanced principle. The linear push of the sampling inner tube allows the material to flow naturally into the outlet by gravity, which effectively reduces the problem of jamming during the sampling process and prevents the waste of materials in batches, reducing the economic losses for users.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0021] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0024] This utility model discloses a telescopic granular material sampling device, such as... Figure 1-3 As shown, it includes an outer sampling tube 2 connected at one end to the opening of the side wall of the silo 1, and an inner sampling tube 4 fitted inside the outer sampling tube 2 and capable of telescopic movement along the outer sampling tube 2 under the action of the drive component 3. The inner sampling tube 4 has a feed inlet 5 at its front end and a discharge hole 7 at its rear end corresponding to the discharge outlet 6 on the outer sampling tube 2. When the inner sampling tube 4 extends forward, the feed inlet 5 is connected to the inside of the silo 1, and the discharge hole 7 is not connected to the discharge outlet 6. When the inner sampling tube 4 retracts backward, the feed inlet 5 is not connected to the inside of the silo 1, and the discharge hole 7 is connected to the discharge outlet 6.

[0025] The sampling inner tube 4 has a closed structure at both its front and rear ends. The inlet 5 is located above the front side wall of the sampling inner tube 4, and the outlet 7 is located below the rear side wall of the sampling inner tube 4. In order to allow the material to flow naturally downward under the action of gravity, the sampling outer tube 2 is inclinedly connected to the side wall of the hopper 1. That is, the sampling inner tube 4 is also inclined along with the sampling outer tube 2. Preferably, the angle between the sampling outer tube 2 and the horizontal plane is 60°. Furthermore, the outlet 6 is located below the sampling outer tube 2 and is designed to be perpendicular to the horizontal plane. That is, the angle between the outlet 6 and the sampling outer tube 2 is 30°.

[0026] To ensure the stability of the connection between the outer sampling tube 2 and the inner sampling tube 4, an isolation ring 8 is provided between the outer sampling tube 2 and the inner sampling tube 4, and a positioning ring 9 is also provided between the front ends of the outer sampling tube 2 and the inner sampling tube 4. The material of the isolation ring 8 and the positioning ring 9 can be PTFE, and the material of the outer sampling tube 2 and the inner sampling tube 4 can be stainless steel. Of course, the specific material selection can be determined according to different working conditions, and no specific restrictions are imposed.

[0027] The drive assembly 3 includes a telescopic cylinder 10, and a filter pressure reducing valve 11 and a manual control valve 12 connected to the telescopic cylinder 10.

[0028] When using this telescopic granular material sampling device, the telescopic cylinder 10 is controlled by the hand control valve 12 to push the sampling inner tube 4 forward, so that the feed port 5 is exposed in the hopper 1. The material flows into the sampling inner tube 4 through the feed port 5 and is stored. The telescopic cylinder 10 retracts, and the telescopic cylinder rod pulls the sampling inner tube 4 backward. The material stored in the sampling inner tube 4 flows out through the discharge hole 7 below the sampling inner tube 4 under the action of gravity, and is discharged from the discharge port 6 below the sampling outer tube 2, thus completing the sampling.

[0029] In summary, the telescopic granular material sampling device provided by this utility model has a relatively simple structure and an advanced principle. It linearly pushes the sampling inner tube, and the material flows naturally into the outlet by gravity. This can more effectively reduce the problem of jamming in the sampling inner tube during the sampling process, and at the same time, it can effectively prevent the material from being scrapped in batches, reduce the economic losses of users, and has great market value. It is worth promoting and applying widely.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
