Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulp sampling tools, in particular to a sampler. Background Art
[0002] At present, the pulp and make-up water in the pump tank of the slurry pump are mixed and then pumped into the next process. When inspecting this process, tools are needed to reach the bottom of the pump tank of the slurry pump to take samples for testing and analysis. However, the pulp is generally very thick. After water is added to the pulp, the water is located on the upper layer of the pulp and cannot be evenly mixed with the pulp. Therefore, when taking samples, it is necessary to take the pulp at the bottom of the pump tank. Therefore, there is an urgent need for a tool that can take samples at the bottom of the pump tank. Summary of the Utility Model
[0003] The utility model aims at the deficiencies of the prior art and provides a sampler.
[0004] The technical solution for the utility model to solve the above technical problems is as follows:
[0005] A sampler, comprising a sampling bucket, wherein a sampling port is penetrated through the side wall of the sampling bucket, at least one sampling port is provided, sealing rings are arranged on both the upper edge and the lower edge of the sampling port, a central rod is arranged in the sampling bucket, a blocking piece is arranged at the end of the central rod, the blocking piece is located between the upper edge and the lower edge of the sampling port, and when the blocking piece abuts against the sealing ring at the lower edge, the blocking piece is used to seal the bottom of the sampling bucket, and when the blocking piece abuts against the sealing ring at the upper edge, the blocking piece is used to open the bottom space of the sampling bucket.
[0006] By adopting the above technical solution, the central rod is pushed to push the blocking piece to abut against the sealing ring at the lower edge to seal the bottom of the sampling bucket, and then the sampling bucket is extended to the bottom of the pump tank, and then the central rod is pulled to pull the blocking piece to abut against the sealing ring at the upper edge to open the bottom space of the sampling bucket, and the pulp enters the bottom of the sampling bucket from the sampling port to achieve the sampling purpose. The structure is simple to operate and has strong practicability; among them, because of the setting of the sampling port, the height of the sample is not higher than the position of the lower edge of the sampling port. During the process of taking the sampling bucket out of the pump tank, the sample has been obtained at the bottom of the sampling bucket, and the sampling bucket does not need to be sealed, and the pulp and water in the pump tank can flow through the sampling port and will not enter the bottom of the sampling bucket again.
[0007] Furthermore, a sleeve rod is slidably connected to the end of the central rod away from the blocking piece, fixed rods are fixedly connected to both sides of the sleeve rod, and the ends of the fixed rods away from the sleeve rod are fixedly connected to the sampling bucket.
[0008] By adopting the above technical solution, the operator fixes the position of the sleeve rod to fix the position of the sampling bucket, and then pushes the central rod. This is equivalent to fixing the position of the sampling bucket and then pushing the central rod so that the sealing piece abuts against the sealing ring on the lower edge. When the sampling bucket is inserted into the bottom of the pump sump, the sampling bucket can be smoothly inserted into the bottom of the pump sump, preventing the slurry or water in the upper part of the pump sump from entering the bottom of the sampling bucket due to the floating of the sampling bucket. At the same time, when the sampling is completed and the sampling bucket is taken out, the operator fixes the sleeve rod to fix the position of the sampling bucket, and then pushes the central rod. The central rod drives the sealing piece to slide, making the sealing piece abut against the sealing ring on the lower edge, reducing the possibility that the sealing piece does not contact the sealing ring on the lower edge due to the unfixed position of the sampling bucket when the operator pushes the central rod, thereby achieving the purpose of re-sealing the bottom of the sampling bucket and further ensuring that the sample is the slurry at the bottom of the pump sump.
[0009] Further, a push-pull rod is provided at one end of the central rod away from the sealing piece, and an included angle exists between the push-pull rod and the central rod.
[0010] By adopting the above technical solution, the setting of the push-pull rod can facilitate the operator to push and pull the central rod, improving the convenience when operating the central rod.
[0011] Further, the push-pull rod is perpendicular to the central rod.
[0012] Further, the central rod is fixedly arranged in the middle of the sealing piece.
[0013] By adopting the above technical solution, the sealing piece moves more smoothly between the upper edge and the lower edge of the sampling port, preventing the sealing piece from tilting.
[0014] Further, four sampling ports are provided, and the four sampling ports are evenly arranged along the circumference of the sampling bucket.
[0015] By adopting the above technical solution, the setting of the four sampling ports makes the sampling faster and more convenient.
[0016] Further, the sampling bucket is frustum-shaped. Description of the Drawings

[0020] The principles and features of the present utility model will be described below in conjunction with all the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0021] An embodiment of the present utility model discloses a sampler.
[0022] Referring to Figure 1 - Figure 2 , a sampler includes a sampling bucket 1. The sampling bucket 1 is a frustum-shaped sampling bucket 1 in this embodiment, and can also be a sampling bucket 1 of other shapes. A sampling port 2 is formed through the side wall of the sampling bucket 1. The sampling port 2 is spaced from the bottom of the sampling bucket 1 by a certain height to form a storage space for storing pulp. At least one sampling port 2 is provided. In order to improve the speed and efficiency during sampling, four sampling ports 2 are provided in this embodiment, and the four sampling ports 2 are evenly arranged along the circumferential direction of the sampling bucket 1. Sealing rings 3 are provided on both the upper edge and the lower edge of the sampling port 2. As shown in Figure 2 , the sealing ring 3 can be a continuous ring shape or a non-continuous shape. A central rod 4 is provided in the sampling bucket 1, and a blocking piece 6 is provided at the end of the central rod 4. The blocking piece 6 is located between the upper edge and the lower edge of the sampling port 2, that is, the vertical sliding distance of the blocking piece 6 is the distance between the sealing ring 3 on the upper edge and the sealing ring 3 on the lower edge. When the blocking piece 6 abuts against the sealing ring 3 on the lower edge, the blocking piece 6 is used to seal the bottom of the sampling bucket 1 to prevent pulp and water from entering the bottom of the sampling bucket 1 through the sampling port 2. When the blocking piece 6 abuts against the sealing ring 3 on the upper edge, the blocking piece 6 is used to open the sampling port 2 to facilitate the pulp to enter the bottom of the sampling bucket 1 through the sampling port 2.
[0023] When sampling is required, first push the central rod 4 to push the blocking piece 6 to abut against the sealing ring 3 on the lower edge to seal the bottom of the sampling bucket 1. Then, insert the sampling bucket 1 to the bottom of the pump tank, and then pull the central rod 4 to pull the blocking piece 6 to abut against the sealing ring 3 on the upper edge to open the bottom space of the sampling bucket 1, and the pulp enters the bottom of the sampling bucket 1 through the sampling port 2 to achieve the purpose of sampling. This structure is simple to operate and highly practical. Among them, due to the setting of the sampling port 2, the height of the sample in the sampling bucket 1 is not higher than the lower edge position of the sampling port 2. During the process of taking out the sampling bucket 1 from the pump tank, the sample has been obtained at the bottom of the sampling bucket 1. The blocking piece 6 seals the sample in the sampling bucket 1, and the pulp and water in the pump tank can flow through the sampling port 2 and will not enter the storage space at the bottom of the sampling bucket 1 again, ensuring the accuracy of sample detection and analysis.
[0024] The central rod 4 is fixedly connected to the middle position of the blocking piece 6, making the central rod 4 more stable when pushing the blocking piece 6 and preventing the blocking piece 6 from tilting.
[0025] Referring to Figure 1 and Figure 2, a sleeve rod 7 is slidably connected to one end of the central rod 4 away from the plugging piece 6. Fixed rods 8 are fixedly connected to both sides of the sleeve rod 7. One end of the fixed rod 8 away from the sleeve rod 7 is fixedly connected to the sampling bucket 1. As Figure 2 shown, when the operator slides the sleeve rod 7, the sampling bucket 1 can be driven to move. When the operator fixes the position of the sleeve rod 7 and pushes the central rod 4, it is equivalent to fixing the position of the sampling bucket 1 and only pushing the central rod 4. By sliding the central rod 4, the plugging piece 6 is driven to slide, so as to achieve the purpose that the plugging piece 6 always abuts against the sealing ring 3 on the lower edge during the process of inserting the sampling bucket 1 to the bottom of the pump sump. When the sampling bucket 1 is inserted to the bottom of the pump sump, the sampling bucket 1 can be smoothly inserted to the bottom of the pump sump to take a sample from the bottom of the pump sump. The purpose of this operation is to prevent the sampling bucket 1 from floating, so as to prevent the pulp or water in the upper part of the pump sump from entering the bottom of the sampling bucket 1, thereby reducing the error of the detection result. After the sampling bucket 1 reaches the bottom of the pump sump, the operator fixes the sleeve rod 7 and pulls the central rod 4 to make the plugging piece 6 abut against the sealing ring 3 on the upper edge, so that the pulp at the bottom of the pump sump enters the bottom of the sampling bucket 1 from the sampling port 2; when the sampling is completed and the sampling bucket 1 is taken out, the operator fixes the sleeve rod 7 to fix the position of the sampling bucket 1, and then pushes the central rod 4. The central rod 4 drives the plugging piece 6 to slide, and the plugging piece 6 abuts against the sealing ring 3 on the lower edge again to seal the bottom of the sampling bucket 1 again, so as to further ensure that the sample is the pulp at the bottom of the pump sump when the sampling bucket 1 is taken out from the bottom of the pump sump. As Figure 2 shown.
[0026] A push-pull rod 5 is provided at one end of the central rod 4 away from the plugging piece 6. There is an included angle between the push-pull rod 5 and the central rod 4. In this embodiment, the included angle between the push-pull rod 5 and the central rod 4 is 90°, that is, the push-pull rod 5 is perpendicular to the central rod 4. The setting of the push-pull rod 5 can facilitate the operator to push and pull the central rod 4 and improve the convenience of operating the central rod 4.
[0027] 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 shall be included in the protection scope of the present invention.
