Particles for crushing sample through collision

Abstract

The invention discloses a method for crushing particles of a sample by collision. The particles are excited by the power source to collide with the sample in the same chamber, so that the sample is crushed. The particles can be made of different materials including but not limited to metal, glass, ceramic and plastic. The particles can be repeatedly used and can also be used in a disposable mode. The particles are non-spherical particles formed by two or more than two planes or curved surfaces.

Description

Technical Field

[0001] The invention relates to the fields of chemical engineering, biological research and detection technology, and in particular to particles capable of crushing samples through collision. Background Art

[0002] Chemical and biological research and testing often involve sample crushing.

[0003] Existing sample crushing systems are typically driven by a motor, causing spherical particles made of metal, glass, or zirconium oxide (hereinafter referred to as spherical particles) to collide with the sample within a sealed chamber to achieve sample crushing. The spherical particles have a single curved surface, and the collision with the sample is a point (sample)-plane (spherical particle) collision. This point-plane collision results in poor crushing of the spherical particles due to the large contact area and the resulting low pressure.

[0004] When using a sample chamber with an inner surface having an angle, the spherical particles cannot collide with the sample within the angle, resulting in some samples being unable to be crushed. Summary of the Invention

[0005] The object of the present invention is to provide particles for crushing samples by collision, thereby solving the problems raised in the background art.

[0006] To achieve the above object, the present invention provides the following technical solution: non-spherical particles are formed by using two or more planes or curved surfaces.

[0007] The intersection of the planes or curved surfaces forms an intersection line.

[0008] The intersection line can produce point (sample) and line (intersection line) collision with the sample during movement, which greatly improves the crushing effect.

[0009] When using a sample chamber with an angle on the inner surface, the intersection line can penetrate into the angle during movement and collide with the sample within the angle, thereby improving the crushing effect.

[0010] As a preferred embodiment of the present invention, the non-spherical particles are cylinders with a curved surface at one end and a flat surface at the other end, wherein intersection lines are formed between the curved surface and the cylinder, and between the flat surface and the cylinder.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the present invention can cause point (sample) and line (intersection line) collision with the sample to be crushed, thereby improving the crushing effect.

[0012] The intersection line in the present invention can collide with the sample at the angle of the sample chamber, thereby improving the crushing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The accompanying drawings are used to provide further understanding of the present invention and constitute a part of the specification. They are used to explain the present invention together with the embodiments of the present invention and do not constitute a limitation of the present invention.

[0014] In the accompanying drawings: Figure 1 is a side view and a top view of a particle for crushing a sample by collision according to the present invention. In the figure: 1, particle plane; 2, particle body; 3, particle curved surface. DETAILED DESCRIPTION

[0015] 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.

[0016] 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.

[0017] 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.

[0018] See also Figure 1 , the present invention provides a technical solution: a particle for crushing a sample by collision, comprising a particle plane 1, a particle body 2, and a particle curved surface 3; The particle plane 1 forms a circular intersection line with the particle body 2; the particle body 2 forms another circular intersection line with the particle curved surface 3. Compared to existing spherical particles, the present invention is distinguished by the addition of a new intersection line. When these two intersection lines collide with a sample, a point (sample) and line (intersection line) collide, resulting in a more effective crushing effect than the point (sample) and surface (curved surface) collision of spherical particles. Furthermore, compared to spherical particles, the newly added intersection line of the present invention can collide with samples within the sample chamber angle, thereby enhancing the crushing effect.

[0019] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims are included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0020] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
