Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample sampling technology, specifically a ton bag bentonite sampling needle. Background Technology
[0002] Bentonite used in pelletizing (mineral ore pelletizing) is a light yellow, loose, earth-like powder. Its main chemical components are silicon dioxide, aluminum oxide, and water, and it is usually packaged in ton bags. To ensure that the quality of the bentonite entering the plant meets the requirements of pellet production, it is necessary to sample and test the composition of the bentonite after it arrives at the plant. The current sampling method is bag-turning sampling, which involves numbering all the bentonite ton bags in a truck, drawing lots to determine the bag numbers to be sampled, turning them out, and turning them over to form small piles on the ground (three bags need to be turned over for sampling per truck). Then, a sampling shovel is used to take samples from the piles. However, the above operation occupies a large area and requires the cooperation of forklifts, cranes, and other equipment to complete. In particular, the bagging of bentonite after sampling is time-consuming and labor-intensive, resulting in high labor intensity for sampling personnel and seriously affecting work efficiency. To reduce labor intensity and improve work efficiency, there are some bentonite sampling devices on the market, such as Chinese patents CN215953028U-A Bentonite Sampling Device, CN213364285U-A Bentonite Sampling Device, CN219455539U-A Bentonite Sampling Device, etc. However, the above-mentioned bentonite sampling devices are not easy to carry due to their complex structure, and the sampling operation is still cumbersome. Utility Model Content
[0003] The purpose of this invention is to provide a simple and easy-to-operate bentonite sampling needle for ton bags, so as to solve the problems of the bentonite sampling device mentioned in the background art being inconvenient to carry and cumbersome to operate.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A sampling needle for bentonite in ton bags includes a sampling tube and a material extraction structure. The sampling tube has a sampling cavity arranged along its length. The sampling cavity is a channel that is open at one end and closed at the other end. The open end of the sampling cavity forms a discharge port, and the closed end of the sampling cavity is connected to a tip. An inlet communicating with the sampling cavity is opened on the tube wall near the tip of the sampling tube. The material extraction structure is arranged in the sampling cavity to guide the sample from the inlet into the sampling cavity.
[0006] Preferably, the material extraction structure includes an inner extraction rod and a plug. One end of the inner extraction rod is inserted into the material extraction chamber, and the other end extends from the material outlet to the outside of the material extraction chamber. The end of the inner extraction rod inserted into the material extraction chamber is connected to the plug at the inlet position.
[0007] Preferably, the material extraction structure includes an inner rod handle, which is connected to one end of the inner rod extending out of the material extraction port.
[0008] Preferably, the diameter of the plug is smaller than the inner diameter of the material extraction chamber, and the diameter of the plug is larger than the diameter of the material extraction rod.
[0009] Preferably, the feed inlet is an elongated hole, and the diameter of the plug is larger than the width of the feed inlet.
[0010] Preferably, the inner rod handle is perpendicular to the inner rod for material extraction.
[0011] Preferably, the tip is a conical structure.
[0012] Preferably, the sampling tube has two outer tube handles arranged opposite each other on the outer tube wall at one end of the sampling port.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By opening a feed inlet on the sampling tube and pre-blocking the feed inlet with a material extraction structure, when sampling, the protrusion is aligned with the position to be sampled in the ton bag, and the sampling tube is inserted into the required sampling depth with the protrusion tilted upwards during insertion. Finally, the material extraction structure is pulled out of the sampling tube and the sampling tube is gently shaken to allow bentonite to enter the sampling tube from the feed inlet. Its structure is simple, easy to carry, and convenient to operate, thus improving sampling efficiency.
[0015] 2. Since the diameters of the plug and the inner rod are smaller than the diameter of the sampling chamber, a gap is reserved between the plug, the inner rod and the inner wall of the sampling chamber to avoid excessive friction between the plug, the inner rod and the inner wall of the sampling chamber, making it easier to pull out the inner rod and saving sampling effort.
[0016] 3. The inlet of the sampling tube is an elongated hole, and the diameter of the plug is larger than the width of the inlet, so that the plug can block the inlet. The inner rod handle is perpendicular to the inner rod for drawing material, and the outer cylinder handle is perpendicular to the sampling tube, so that the sampling personnel can insert the sampling tube into the sample by firmly grasping the inner rod handle and / or the outer cylinder handle.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Please see Figure 1-3 A sampling needle for bentonite in ton bags includes a sampling tube 1 and a material extraction structure 2. The sampling tube 1 has a sampling cavity 11 arranged along its length, which is an open-end and closed-end channel. The open end of the sampling cavity 11 forms a discharge port 12, and the closed end of the sampling cavity 11 is connected to a protrusion 3. The protrusion 3 guides the sampling tube 1 into the bentonite sample. The protrusion 3 has a conical structure to facilitate insertion into the bentonite sample for sampling. An inlet 13 communicating with the sampling cavity 11 is opened on the tube wall near the protrusion 3, through which the bentonite sample enters the sampling cavity 11. The material extraction structure 2 is disposed within the sampling cavity 11 and guides the sample from the inlet 13 into the sampling cavity 11.
[0024] This embodiment features an inlet 13 on the sampling tube 1, which is pre-blocked by a material extraction structure 2. During sampling, the protrusion 3 is aligned with the desired sampling location on the ton bag, and the sampling tube 1 is forcefully inserted to the required depth, with the protrusion 3 tilted upwards during insertion. Finally, the material extraction structure 2 is pulled out of the sampling tube 1, and the tube 1 is gently shaken to allow bentonite to enter through the inlet 13. This design is simple, portable, and convenient, improving sampling efficiency.
[0025] Please see Figure 1 as well as Figure 3The material extraction structure 2 includes an inner extraction rod 21 and a plug 22. One end of the inner extraction rod 21 is inserted into the material extraction chamber 11, and the other end extends out of the material extraction chamber 11 from the discharge port 12. The end of the inner extraction rod 21 inserted into the material extraction chamber 11 is connected to the plug 22, which is sealed at the inlet 13. In addition, the material extraction structure 2 also includes an inner rod handle 23, which is connected to the end of the inner extraction rod 21 that extends out of the discharge port 12, for the sampling personnel to hold. The sampling personnel can easily and effortlessly extract the inner extraction rod 21 from the material extraction chamber 11 using the inner rod handle 23.
[0026] In this embodiment, the plug 22 is cylindrical, and its diameter is smaller than the inner diameter of the sampling chamber 11, while its diameter is larger than the diameter of the inner rod 21. Therefore, since the diameters of both the plug 22 and the inner rod 21 are smaller than the diameter of the sampling chamber 11, a gap is provided between the plug 22, the inner rod 21, and the inner wall of the sampling chamber 11. This prevents excessive friction between the plug 22, the inner rod 21, and the inner wall of the sampling chamber 11, facilitating the extraction of the inner rod 21 and saving sampling effort.
[0027] Please see Figure 1-2 The inlet 13 on the sampling tube 1 is an elongated hole, and the diameter of the plug 22 is larger than the width of the inlet 13, so that the plug 22 can seal the inlet 13. The inner rod handle 23 is perpendicular to the inner rod 21 for drawing material. Two outer cylinder handles 4 are arranged opposite each other on the outer tube wall of the sampling tube 1 at one end of the sampling port. In this embodiment, the outer cylinder handles 4 are perpendicular to the sampling tube 1, which makes it convenient for the sampling personnel to insert the sampling tube 1 into the sample by firmly gripping the inner rod handle 23 and / or the outer cylinder handles 4.
[0028] The sampling needle for bentonite in this embodiment, which uses the sampling tube 1 in conjunction with the inner rod 21, not only solves the problems of existing bag-turning sampling methods that require a large space, forklifts and cranes, and time-consuming and labor-intensive bagging of bentonite after sampling, but also features simple structure, easy portability, simple operation, good performance, and low manufacturing cost. It effectively reduces the high labor intensity of bag-turning sampling personnel and the serious impact on work efficiency. Sampling can be carried out anytime and anywhere, without being limited by space or site, and the sampling efficiency is high.
[0029] The working principle of this utility model of a bentonite sampling needle for ton bags is as follows: When sampling, first number all the bentonite ton bags in the truck; after confirming the bag number to be sampled by lottery, use this sampling needle for sampling. During sampling, first insert the inner rod 21 into the sampling chamber 11 inside the sampling tube 1, and use the plug 22 to block the inlet 13; then align the protrusion 3 with the position on the ton bag where sampling is required. At this time, adjust the inlet 13 upwards, firmly grasp the inner rod handle 23 with both hands, and forcefully insert the protrusion 3 along with the sampling tube 1 into the bentonite sample to the required sampling depth; during insertion, the protrusion 3 must be kept tilted upwards to ensure... Hold the sampling tube 1 at an angle of about 20-30° to the horizontal to allow the bentonite sample to slide into the inlet 13. Then, pull out the inner rod 21 from the sampling chamber 11 of the sampling tube 1 and gently shake the sampling tube 1 to allow the bentonite sample to enter the sampling tube 1 from the inlet 13. The bentonite sample slides down the sampling chamber 11 of the sampling tube 1 and enters the sampling bag (bucket) from the outlet 12. Repeat the above operation at different sampling points. Generally, one truckload is one batch. In principle, each batch should have no less than 3 bags, and 3-5 points should be taken from each bag. If the total sample volume is insufficient, increase the number of sampling points as needed.
[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
