Description

Technical Field

[0001] This utility model relates to a positioning sampler suitable for powder or granular raw materials. Background Technology

[0002] In the pharmaceutical and chemical industries, multi-depth sampling and testing are required to ensure the uniformity of quality characteristics of stirred powders or granules in containers. For multi-depth sampling and testing, the ability to accurately sample powders or granules from various parts of the container is a prerequisite. Existing particle or powder sampling devices are described in Chinese Patent CN201711138989.2. However, the containers used to store powders or granules in the pharmaceutical and chemical industries are large and deep, making existing sampling devices unsuitable. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a positioning sampler suitable for powder or granular raw materials, which can sample powder or granules at different depths in a deep container without causing pollution.

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning sampler suitable for powder or granular raw materials, including a hollow cylindrical body arranged vertically and sealed on both the top and bottom. A vertically arranged T-shaped handle is provided on the upper side of the cylindrical body, and a cone-shaped guide with its tip pointing vertically downwards is provided on the lower side of the cylindrical body. A scale is provided on the outer circumference of the cylindrical body. A horizontally arranged partition is provided inside the cylindrical body, dividing the inner cavity of the cylindrical body into an upper compartment and a lower compartment. An opening is provided on the side wall corresponding to the lower compartment, connecting the inside and outside of the lower compartment. A vertically arranged movable flap is provided at the opening, and a horizontal rotating shaft is provided at the center of the movable flap in the height direction. The axis of the horizontal rotating shaft is parallel to the movable flap. The arrangement is as follows: the movable flap is connected to the cylindrical body via a horizontal pivot. A first guide ring is provided on the outer wall of the cylindrical body, corresponding to the position above the movable flap, extending radially outward along the cylindrical body. A first pull rope is provided on the upper outer side of the movable flap. The other end of the first pull rope, away from the movable flap, extends upward through the first guide ring and continues upward beyond the upper side of the cylindrical body, where it is connected to a first pull ring. A second guide ring is provided on the inner wall of the lower compartment, opposite to the opening, extending radially inward along the cylindrical body. A second pull rope is provided on the lower inner side of the movable flap. The end of the second pull rope, away from the movable flap, first extends horizontally through the second guide ring, and then continues upward, passing through the partition and the top of the cylindrical body in sequence, where it is connected to a second pull ring.

[0005] For the sake of simplicity, the positioning sampler applicable to powder or granular raw materials described in this utility model will be referred to as "this sampler" in the following description.

[0006] Instructions for using this sampler: First, place the sampler on the container containing powder or granular raw material. Pull the first pull ring upwards and hold it. Then, press down the T-shaped handle to insert the sampler into the raw material. Use the scale to control the opening of the sampler to reach the target depth. At this point, release the first pull ring and pull the second pull ring upwards. The second pull ring pulls the movable flap around the axis via the second pull rope. Simultaneously, control the T-shaped handle to swing the sampler horizontally. The powder or granular raw material in the container will enter the lower compartment through the gap between the movable flap and the opening. Then, release the second pull ring and pull the first pull ring upwards again. The first pull ring pulls the movable flap in the opposite direction via the first pull rope, causing the movable flap to re-engage with the opening. While keeping the first pull ring pulled upwards, lift the T-shaped handle upwards to pull the sampler out as a whole. After the sampler is pulled out, rotate the flap to pour out the sample in the lower compartment, thus completing one sampling.

[0007] Advantages of this sampler: This sampler can accurately sample powders or particles at different depths in deep containers, and since the lower chamber, which serves as the sample chamber, is closed before and after sampling, it will not contaminate the raw materials inside the container.
