Technical Field

[0001] The invention relates to the technical field of material sampling, and in particular to a rapid ore sample reduction device and a sorting method thereof. Background Art

[0002] Sample reduction is one of the steps in sample processing such as chemical analysis. It is the process of dividing a sample with a certain particle diameter into several samples with equal reliability. The purpose of sample reduction is to take out some fairly representative samples while ensuring the reliability of the samples, so as to reduce the amount of samples for subsequent processing.

[0003] The traditional method of reducing mineral samples is to use manual reduction method, which is carried out through tools such as binary dividers. Although the reduction process is simple to operate, the procedure is complicated, takes a long time, and the dust pollution is serious, which endangers the health of operators.

[0010] It also includes a control box arranged on the frame, and the control box is electrically connected to the driving motor and the vibration motor.

[0011] Furthermore, the linear guide rails are two symmetrically arranged horizontally, the two-divider is arranged horizontally, the material receiving trough is symmetrically arranged on both sides below the two-divider, and the material receiving trough is coordinated with the material dividing port of the two-divider.

[0012] Furthermore, the feed hopper is C-shaped, one end of which is arranged below the discharge port, and the other end of the feed hopper is arranged above the divider. The feed hopper generates vibration through a vibration motor to send the material from the discharge port to the divider.

[0013] Furthermore, the stirring assembly includes a stirring motor, a stirring shaft, and stirring blades.

[0017] S3: Dividing: The sample divider divides the incoming materials into equal parts and then enters the receiving trough;

[0018] S4: Inspection: Send the receiving trough containing the reduced materials to the inspection room for inspection;

[0019] In step 2 and step 3, the sample divider is a binary divider.

[0020] The advantages of the present invention over the prior art are as follows: the present invention uses a stirring assembly in the stirring barrel to make the materials more evenly mixed before shrinking; the driving motor drives the slider on the linear guide to slide back and forth, driving the divider to slide back and forth, so that the materials are more evenly fed into the divider through the feed hopper, and the material shrinking is more accurate.

[0035] In specific implementation, after putting the material into the mixing barrel, the mixing component mixes the material more evenly. Start the vibration motor and the drive motor, and the material falls from the outlet of the mixing barrel to the feed hopper. The feed hopper is tilted, and the end close to the mixing barrel is higher than the other end. The vibration motor drives the feed hopper to vibrate, and the material rolls from the high end to the low end under its own gravity and vibration, and finally falls into the divider.

[0036] The linear guides are two parallel horizontally arranged, one end of which is provided with a driving motor, and the two linear guides are connected by a transmission shaft. The driving motor, linear guide and slide form an electric slide belt synchronous belt slide module, a high-speed reciprocating linear guide module.

[0043] The present invention also discloses a method for rapid stirring and shrinking of a mineral sample, comprising the following steps:

[0044] S1: Feeding: put the material into the mixing barrel through the feed port;

[0045] S2: Stirring: The stirring component in the stirring barrel stirs the materials to make the materials more evenly mixed, and the stirred materials are sent into the sample divider through the feed hopper;

[0046] S3: Dividing: The sample divider divides the incoming materials into equal parts and then enters the receiving trough;

[0047] S4: Inspection: Send the receiving trough containing the reduced materials to the inspection room for inspection;

[0048] In step 2 and step 3, the sample divider is a binary divider.

[0049] During the specific implementation of the present invention, it is only necessary to put the material into the mixing barrel and operate the control box to automatically complete the mixing and shrinking of the material, which greatly reduces the labor intensity in the shrinking process and improves the shrinking efficiency; the reciprocating motion of the divider allows the material to be shrunk more evenly through the divider, and the shrinking accuracy is higher.

[0050] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
