Description

Technical Field

[0001] The present application relates to the technical field of graphite production, and in particular to a sampling mechanism for spot checks. Background Art

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties, corrosion resistance, and low reactivity with acids and alkalis. Natural graphite comes from graphite deposits, but it can also be made from petroleum coke, asphalt coke, and other raw materials through a series of processing steps to produce artificial graphite. The process of preparing graphite from activated carbon includes activation, acid washing, and passivation. After activation, the activated carbon is sampled and tested in ton bags. If the sample fails the test, the entire bag must be reactivated. However, during the activation process, the ton bags are tied to the discharge port. Sampling requires unbundling the ton bags, which is not only time-consuming and laborious, but also, since the activated carbon is in powdered form, sample collection from the ton bags can cause the powder to escape, exacerbating the harsh production environment. Utility Model Content

[0003] In order to address the deficiencies of the above-mentioned prior art, the present application provides a sampling mechanism for spot checks, which is not only simple and convenient for sampling, but also avoids aggravating the severity of the production environment.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A sampling mechanism for spot checks is provided on a discharge pipe, one end of which is arranged higher than the other end, and the interior of the discharge pipe is used to pass the material to be discharged. A sampling tube is vertically and through-through provided on the middle side wall of the discharge pipe, and the sampling tube is movable along its own axial direction, and a sampling groove is provided above the sampling tube.

[0006] The beneficial effect of the utility model is that a sampling tube is provided on the side wall of the discharge pipe to sample the activated material, thereby avoiding the dust raised by sampling from the ton bag and preventing the aggravation of the severity of the production environment.

[0011] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0012] The present application provides a sampling mechanism for spot check, such as Figure 1-Figure 3 As shown, the discharge pipe 1 is located on a vertical axis, with one end of the pipe higher than the other. The material to be discharged passes through it. In this embodiment, the discharge pipe 1 is vertically positioned, with the upper end connected to the activation equipment and the lower end connected to the ton bag. The activated material from the activation equipment passes through the discharge pipe 1 and is collected by the ton bag. A sampling pipe 2 is vertically and continuously installed on the sidewall of the discharge pipe 1. The sampling pipe 2 is arranged to move along its own axis, and a sampling slot 3 is located above the sampling pipe 2.

[0013] When sampling is not in progress, sampling slot 3 is located outside of discharge tube 1. That is, the distance between the end of sampling tube 2 facing away from discharge tube 1 and the axis of discharge tube 1 is at a preset maximum value, and sampling tube 2 is in its initial position. To sample, sampling tube 2 is moved toward the interior of discharge tube 1, positioning sampling slot 3 within the interior to facilitate sampling of material passing through discharge tube 1. Once sampling is complete, sampling tube 2 is moved outward, positioning sampling slot 3 outside of discharge tube 1 to facilitate random inspection of the material.

[0014] Specifically, such as Figure 3 As shown, the sampling tube 2 is arranged to rotate around its own axis. When the sampling tube 2 is in the sampling process, a part of the material will remain in the range outside the sampling groove 3. After the previous round of sampling and inspection is completed, the sampling tube 2 can be moved inward and then rotated to pour this part of the material back into the discharge pipe 1 to avoid affecting the next round of sampling and inspection.

[0015] Specifically, such as Figure 2 and Figure 3 As shown, a spring 4 is provided inside the discharge tube 1. The spring 4 is provided between one end of the sampling tube 2 facing the discharge tube 1 and the inner wall of the discharge tube 1 on the opposite side of the sampling tube 2. When the spring 4 is in a natural state, the sampling tube 2 is in an initial position. To move the sampling tube 2 toward the inside of the discharge tube 1, an external force needs to be applied to the sampling tube 2, and the spring 4 will be compressed.

[0016] Specifically, such as Figure 3As shown, a connecting disk 5 is coaxially provided at one end of the sampling tube 2 facing the discharge tube 1, and a spring 4 is provided between the end of the connecting disk 5 facing the discharge tube 1 and the inner wall of the discharge tube 1 on the opposite side of the sampling tube 2, and the sampling tube 2 is rotatably arranged relative to the connecting disk 5, and the spring 4 is connected to the connecting disk 5. When the sampling tube 2 rotates, the connecting disk 5 will not rotate, so as to avoid affecting the spring 4 connected thereto.

[0017] Specifically, such as Figure 1-Figure 3 As shown, the sampling slot 3 is formed with sealing sections 21 on both sides of the sampling tube 2 in the axial direction. The end of the sealing section 21 facing the discharge tube 1 mates with the inner wall of the discharge tube 1. The sealing section 21 located at the front side of the sampling slot 3 is used to mate with the inner wall of the discharge tube 1 to achieve a seal when sampling is not in progress. The sealing section 21 located at the rear side of the sampling slot 3 is used to mate with the inner wall of the discharge tube 1 to achieve a seal when sampling is in progress.

[0018] Specifically, such as Figure 1-Figure 3 As shown, a pull ring 6 is provided on the side of the sampling tube 2 away from the discharge tube 1 . The provision of the pull ring 6 facilitates the staff to control the movement of the sampling tube 1 .

[0019] In application, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
