Description

Technical Field

[0001] The utility model belongs to the technical field of bentonite sampling and detection, and particularly relates to a bentonite sampling and detection tooling. Background Art

[0002] During the production process of bentonite, sampling and detection are required. Since bentonite is a powdery material, sampling is relatively difficult. Therefore, in the prior art, such as the publication (announcement) number: CN207703534U, a sampler capable of sampling at different positions is provided. However, when the sampling tube is inserted into the bentonite, the sampling grooves on the outer sampling tube will be filled with bentonite on the sampling path. When the sampling tube rotates, the bentonite filled in the sampling grooves on the outer sampling tube will enter the inner sampling tube, still resulting in a reduction in the accuracy during sample inspection.

[0003] Therefore, an improved technical solution is needed to address the deficiencies of the above prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the above prior art, and the utility model provides a bentonite sampling and detection tooling.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A bentonite sampling and detection tooling, comprising:

[0007] An outer tube;

[0008] A sampling tube, which extends into the outer tube and is slidably assembled with respect to the circumferential and axial directions of the outer tube;

[0009] A plurality of notches are provided on the outer tube and are evenly distributed along its circumferential direction. A plurality of sampling ports corresponding to the notches are provided on the outer wall of the sampling tube. The width of the sampling port in the circumferential direction is not greater than half of the notch. A sealing plate is provided on the sampling tube near the side of the sampling port, and the sealing plate is connected to the sampling tube in a detachable manner.

[0010] Preferably, the thickness and radian of the sealing plate are adapted to the outer tube.

[0011] Preferably, the sealing plate is fixed to the sampling tube by screws.

[0012] Preferably, a conical head is detachably connected to the front end of the outer tube.

[0013] Preferably, end plates are respectively provided at the front end and the rear end of the sampling tube, and a partition is provided inside corresponding to the space between two adjacent sampling ports.

[0014] Preferably, a limiting post corresponding to the sealing plate is provided on the side of the rear end of the sampling tube, and a limiting notch corresponding to the limiting post is provided at the rear end of the outer tube.

[0015] Preferably, a handle extending radially is provided at the rear end of the sampling tube.

[0016] Preferably, the arc angle corresponding to the sampling port is 15 - 30 degrees.

[0017] Preferably, the outer diameter of the sampling tube is adapted to the inner diameter of the outer tube.

[0018] Beneficial effects: The outer tube and the sampling tube are in a sliding fit relationship in the axial and axial directions. During the process of inserting the sampling tooling into the bentonite, the notch of the outer tube and the sampling port of the sampling tube intersect and seal each other. At this time, a sealing plate is provided in the notch at the position corresponding to the sampling port in the sampling state, and the sealing plate and the outer tube are on the same cylindrical surface, so as to avoid the presence of bentonite from other positions in the notch, thereby avoiding cross-contamination of bentonite from different positions.

Therefore, it should not be construed as a limitation to the present utility model. The terms "connected" and "coupled" used in the present utility model should be understood in a broad sense. For example, it may be a fixed connection or a detachable connection; it may be directly connected or indirectly connected through an intermediate component. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0028] Such as Figures 1-4As shown in the figure, a bentonite sampling and testing tooling includes an outer tube 1 and a sampling tube 5. The outer tube 1 is a galvanized steel pipe with a certain length, and the specific length is based on the depth of the bentonite at the required testing position. The sampling tube 5 extends into the outer tube 1 and is slidably assembled with respect to the circumferential and axial directions of the outer tube 1. In this way, the front end of the sampling tube 5 can extend into or withdraw from the outer tube 1 and can rotate relative to each other within the outer tube 1. A plurality of notches 2 are evenly distributed along the circumferential direction of the outer tube 1. The notches 2 can be strip-shaped, and the quantity and position are determined according to the depth of the sample to be taken. A plurality of sampling ports 10 corresponding to the notches 2 are provided on the outer wall of the sampling tube 5. The axial length of the sampling port 10 is the same as that of the notch 2, and the difference lies in that the width in the circumferential direction is smaller than that of the notch 2. Generally, the width of the sampling port 10 in the circumferential direction is not greater than half of the notch 2. A sealing plate 3 is provided on the sampling tube 5 near the side of the sampling port 10. The length of the sealing plate 3 is the same as that of the notch 2, and the difference lies in that the width of the sealing plate 3 in the circumferential direction is not greater than half of the notch 2. Generally, it is preferably that the width of the sealing plate 3 is the same as that of the sampling port 10, or the width of the sealing plate 3 is slightly larger than that of the sampling port 10. The sealing plate 3 is detachably connected to the sampling tube 5 and is installed after the sampling tube 5 is inserted in place. On the one hand, during the process of inserting the sampling tooling into the bentonite, by rotating the sampling tube 5 towards the sampling port 10 side, the sealing plate 3 abuts against the inner wall of the notch 2. At this time, the notch 2 of the outer tube 1 and the sampling port 10 of the sampling tube 5 are staggered and sealed. At this time, a sealing plate 3 is provided at the position of the sampling port 10 corresponding to the sampling state in the notch 2, and the sealing plate 3 and the outer tube 1 are on the same cylindrical surface, so as to avoid the existence of bentonite from other positions in the notch 2. In this way, when sampling is required, rotate the sampling tube 5 towards the side away from the sampling port 10 to make the sampling port 10 and the notch 2 face each other. At this time, under the action of the internal pressure of the bentonite, the bentonite at the notch 2 will be squeezed into the sampling port 10 to achieve sampling, so as to avoid cross-contamination of bentonite from different positions.

[0029] On the other hand, the axial positions of the sampling tube 5 and the outer tube 1 are limited by the sealing plate 3 to ensure the stability of the two during the sampling process.

[0030] In an alternative embodiment, the width of the sealing plate 3 can also be smaller than the sealing opening, or even just a convex strip extending radially along the sampling tube 5. In this way, by rotating the sampling tube 5 towards the sampling port 10 side, the sealing plate 3 abuts against the inner wall of the notch 2 and the side wall of the sampling port 10, so as to seal the sampling port 10. When sampling, the bentonite in the notch 2 is removed by rotating the sealing plate 3, so as to avoid cross-contamination of bentonite.

[0031] In an alternative embodiment, the thickness and radian of the sealing plate 3 are adapted to the outer tube 1, so as to ensure that the outer circumference of the sealing plate 3 and the outer tube 1 are on the same cylindrical surface during the sealing process, thereby reducing the possibility of bentonite remaining in the notch 2.

[0032] In this embodiment, the sealing plate 3 is fixed to the sampling tube 5 by screws. Specifically, a plurality of through holes are provided on the sealing plate 3, and a plurality of corresponding screw holes are provided at a position on the side of the sampling tube 5 close to the sampling port 10, so that the sealing plate 3 can be connected by bolts. After the sampling tooling is withdrawn by reversing the sampling tube 5 to seal the sampling port 10 with the sealing plate 3, the sampling tube 5 can be withdrawn from the outer tube 1 by removing the sealing plate 3.

[0033] In an alternative embodiment, a tapered head 8 is detachably connected to the front end of the outer tube 1. The larger end of the tapered head 8 is fixed to the inner wall of the outer tube 1 by threads, and the smaller end can squeeze open the material during the insertion into the bentonite, reducing the insertion difficulty of the sampling tooling.

[0034] A partition plate 9 corresponding to the space between two adjacent sampling ports 10 is provided inside the sampling tube 5, so that the tooling forms a plurality of independent sampling cavities corresponding to each sampling port 10. End plates are respectively provided at the front end and the rear end of the sampling tube 5, so as to seal the two sampling cavities at the front and rear ends, so that the samples in each area can be detected separately.

[0035] In an alternative embodiment, a limit post 6 corresponding to the sealing plate 3 is provided on the side of the rear end of the sampling tube 5. The limit post 6 extends radially along the sampling tube 5. A limit notch 7 corresponding to the limit post 6 is provided at the rear end of the outer tube 1. After the sampling tube 5 is in place, the limit post 6 is snapped into the limit notch 7, and the sampling tube 5 is limited by the limit notch 7. The width of the limit notch 7 in the circumferential direction is not less than the sum of the widths of the sampling port 10 and the sealing plate 3, so as to ensure that the limit post 6 can satisfy that the sealing plate 3 can completely cover or open the notch 2, and ensure that the sampling tube 5 has enough rotation angle.

[0036] Furthermore, the limit post 6 is located on the same normal line as the center line of the sealing plate 3, so as to intuitively reflect the relative position of the sealing plate 3, and thus it is easy to control the tooling. In order to improve the controllability, a handle 4 extending radially is provided at the rear end of the sampling tube 5.

[0037] In an alternative embodiment, the arc angle corresponding to the sampling port 10 is 15 - 30 degrees, preferably 30°. The outer diameter of the sampling tube 5 is adapted to the inner diameter of the outer tube 1, so as to have sufficient compactness to prevent the bentonite from overflowing from the sampling port 10 and contaminating the bentonite in other sampling ports 10 when the sampling tooling is withdrawn.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of the claims of the present invention awaiting approval.
