Combined sample bin for grinding equipment

Abstract

The invention discloses a sample bin for grinding and crushing samples. The sample bin is connected with a power source and is driven by the power source to vibrate, so that grinding particles in the sample bin collide with a sample to be detected, and the sample is ground and crushed. The sample bin can be made of different materials including but not limited to metal, ceramic and plastic. The sample bin can be repeatedly used and can also be used in a disposable mode. The sample bin is composed of an outer sleeve piece, a first cavity assembly and a second cavity assembly. The size of the outer sleeve piece is matched with the size of the first cavity assembly and the size of the second cavity assembly, and therefore the first cavity assembly and the second cavity assembly are supported. The first cavity assembly and the second cavity assembly are combined to form an inner cavity. A sample to be ground and grinding particles can be placed in the inner cavity.

Description

Technical Field

[0001] The invention relates to the fields of chemical and biological research and detection technology, and in particular to a combined sample bin for grinding equipment. Background Art

[0002] When conducting chemical and biological research and testing, it is often necessary to crush and grind samples.

[0003] Existing grinding systems often use universal test tubes as containers for grinding samples, abrasive particles, and grinding beads. However, the material of universal test tubes is not suitable for some samples to be ground. Universal test tubes are also relatively weak and can break when impacted with abrasive particles and grinding beads. Universal test tubes are usually made of plastic, and samples contaminated by plastic can cause skewed experimental results.

[0004] Existing grinding systems also use dedicated grinding chambers, but they have problems such as complex design, large size and high cost.

[0005] Existing grinding systems usually have a porous carrier to hold the aforementioned universal test tube or dedicated grinding chamber. The porous carrier is bulky and is not conducive to miniaturization of the grinding system. Summary of the Invention

[0006] The object of the present invention is to provide a combined sample chamber for a grinding device, which solves the problems raised in the background art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a combined sample chamber for a grinding device, comprising an outer set, a chamber component 1 and a chamber component 2.

[0008] The chamber component 1 and the chamber component 2 form an inner chamber. The inner chamber can be used to place samples to be tested and grinding particles.

[0009] The size of the sample outer set matches the size of the inner chamber, thereby providing support and positioning for the inner chamber.

[0010] As a preferred embodiment of the present invention, the outer sleeve is a straight cylinder, the inner diameter of which is the same as or similar to the outer diameters of the chamber assembly 1 and the chamber assembly 2, thereby providing support and positioning for the latter two.

[0011] As a preferred embodiment of the present invention, the outer set is connected to a power source.

[0012] In a preferred embodiment of the invention, the first and second chamber components are identical bottomed cylinders. The bottomed cylinders can be combined to form an inner chamber. The inner chamber is located entirely or partially within the outer chamber. The inner chamber can accommodate a sample to be ground and abrasive particles.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention is a special sample chamber for grinding, and its strength is higher than that of a general test tube.

[0014] The present invention can be made of a variety of materials, including but not limited to metal, ceramic, and plastic, thereby avoiding deviations in test results caused by material contamination of the sample.

[0015] The present invention has a simple structure and low cost.

[0016] The invention has a small volume and can be applied to ultra-small low-power consumption grinding equipment.

[0017] The present invention can be deployed modularly and can be used in small single-channel grinding machines or combined together to be used in multi-channel grinding equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0023] See also Figure 2 , the present invention provides a technical solution: a combined sample chamber for a grinding device, comprising an outer set 1, a chamber component 1 2, a chamber component 2 3, and an inner chamber 4; The inner diameter of the outer sleeve 1 is the same as or similar to the outer diameter of chamber assembly 1 2 and chamber assembly 2 3, thereby providing support for chamber assembly 1 2 and chamber assembly 2 3 placed therein. Chamber assembly 1 2 and chamber assembly 2 3 are combined to form an inner chamber 4. The inner chamber 4 can hold samples to be tested and abrasive particles. The right end of the outer sleeve 1 can be connected to a power source in a suitable manner so that the power source can drive the sample chamber to move. When the sample chamber moves, the abrasive particles placed in the inner chamber 4 collide with the sample also placed in the inner chamber 4, thereby achieving grinding of the sample. In this way, the outer sleeve 1, chamber assembly 1 2, chamber assembly 2 3 and inner chamber 4 form a sample chamber with complete functions and a simple and compact structure. Depending on different uses, chamber assembly 2 3 can be installed in a fixed or movable manner.
