Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laboratory sampling, in particular to a laboratory sample mixing and separating device. BACKGROUND

[0002] In the daily work process of the laboratory, sample mixing and separating are extremely critical operation links. The traditional sample separating method has many deficiencies. For example, the naked eye sample separating highly depends on the experience of the operator, and it is difficult to ensure that the amount of each sample is completely consistent, resulting in deviation of the subsequent detection results. When using conventional sample separating equipment such as an electronic scale, the accuracy can be guaranteed, but the sample needs to be weighed and taken frequently, and the sample is easy to be lost during the operation process. The steps are complicated, and a large amount of time and labor cost is required. In the daily work of the laboratory, how to realize efficient, accurate and stable sample separating of each sample amount becomes a difficult problem to be solved in the current laboratory work. CONTENT OF THE INVENTION

[0003] To solve or partially solve the problems in the related art, the present application provides a sample mixing and separating device, which can quickly realize sample separating and taking, and has strong practicality when multiple equal samples are needed.

[0004] The first aspect of the present application provides a laboratory sample mixing and separating device, comprising:

[0005] The mixing device comprises a bin body and a top cover rotationally connected with the bin body. A motor is installed on the upper end of the top cover. A rotating shaft is connected to the output end of the motor and penetrates through the top cover. The rotating shaft extends to the bottom of the bin body, and a plurality of fan blades are installed on the rotating shaft. The bottom of the bin body is in a funnel structure, and a screen is arranged at the discharge port.

[0006] The sample separating device comprises a sample bottle and a sample separating cover. A plurality of sample separating plates are radially distributed at the bottom of the sample separating cover. After the sample separating cover is inserted and installed on the sample bottle, the sample bottle is divided into a plurality of independent areas. A plurality of open and close covers are arranged on the sample separating cover corresponding to the independent areas for independent sample discharge.

[0007] Among them, a plurality of grooves for installing the open and close covers are arranged on the sample separating cover. The open and close covers are embedded and installed in the grooves and are magnetically linked with the sample separating cover.

[0008] The fixing frame is arranged above the mixing device to make the discharge port of the mixing device directly face the central axis of the sample bottle.

[0009] The bottom of the fixing frame is provided with a positioning seat, and a positioning groove is formed in the positioning seat to limit the sample bottle.

[0010] The technical scheme provided by the present application can include the following beneficial effects:

[0011] The application provides a laboratory sample mixing and dispensing device, which has strong practicability when multiple equal samples need to be quickly obtained. The mixing device outputs the sample to a sample bottle after crushing and filtering the sample. A partition plate is inserted into the sample bottle to build multiple sealed areas independent of each other. When the sample in one area is poured out from the top, the samples in other areas are not affected, which effectively guarantees the uniformity of the amount of each sample and lays a solid foundation for subsequent accurate detection. The sample can be taken out by opening the corresponding area from the top when the sample is taken out, which is simple and convenient to operate, greatly saves time and labor cost, and achieves efficient dispensing.

The fixed frame 3 is provided with a positioning seat 31 at the bottom, and the positioning seat 31 is provided with a positioning groove. The positioning groove is used to limit the sampling bottle 1.

[0025] The mixing device 2 comprises a bin body and a top cover 22 rotationally connected with the bin body, an electric machine 21 is installed on the upper end of the top cover 22, a rotating shaft 23 is connected with the output end of the electric machine 21 and penetrates through the top cover 22, the rotating shaft 23 extends to the bottom of the bin body and a plurality of fan blades 24 are installed on the rotating shaft 23. After the sample is weighed and added into the bin body, the top cover 22 is connected with the bin body, and the plurality of samples are crushed and mixed by the electric machine 21. The bottom of the bin body is in a funnel structure, a screen 25 is arranged at the discharge port, and the sample meeting the screen size of the screen 25 is vertically discharged from the discharge port.

[0026] The sample separation device comprises a sample bottle 1 and a sample separation cover 11, the sample bottle 1 is used for receiving the sample vertically falling from the discharge port of the mixing device 2, and the sample is accumulated in the sample bottle 1 to form a conical structure. The bottle body is made of transparent material, which facilitates observation of the sample accumulation and the sample separation process. The bottle opening size is matched with the sample separation cover 11 to ensure the sealing effect. The sample separation cover 11 is connected with a plurality of sample separation plates 13 at the shaft center, and the sample separation plates 13 are distributed in a radial manner, as shown in FIG. 2. Figure 3 The edge of the sample separation cover 11 is provided with a sealing rubber ring, which can ensure the sealing effect when the cover is on the sample bottle. After the sample separation cover 11 is inserted and installed on the sample bottle 1, the sample bottle is divided into a plurality of independent areas, and the sample separation cover 11 is provided with opening and closing covers 12 corresponding to the independent areas for independent sample discharge, as shown in FIG. 3. Figure 2 The shaft center of the sample separation cover 11 coincides with the center axis of the sample bottle to ensure that the separation plates can uniformly separate the sample.

[0027] The sample separation plate 13 has a certain flexibility and strength, can be easily inserted into the sample pile, and can maintain stable shape, the length of the sample separation plate 13 is slightly larger than the radius of the sample bottle to ensure that the sample separation plate 13 can reach the bottle wall after being inserted into the sample bottle to form a complete fan-shaped separation area. The two sides and the bottom of the sample separation plate 13 are provided with sealing rubber strips, which are tightly fitted with the inner wall of the sample bottle to realize the sealing of each area. According to the sample separation requirement, a plurality of specifications of the sample separation cover 11 are made, the bottom of the sample separation cover 11 is provided with 3, 4 or 5 sample separation plates 13, and the sample can be quickly separated into the required number of parts by replacing the sample separation cover 11.

The sample separation cover 11 is provided with a groove for installing the opening and closing cover 12, the opening and closing cover 12 is embedded and installed in the groove and is magnetically linked with the sample separation cover 11, an inner groove is arranged on the side edge of the opening and closing cover 12, and the opening and closing cover 12 is taken down after being buckled on the inner groove to discharge the sample.

[0029] After the sample is mixed in the mixing device, it falls into the sampling bottle 1. The funnel-shaped structure of the sampling bottle 1 allows the sample to accumulate in a conical sample pile. After the sample dividing cover 11 is vertically inserted into the sampling bottle 1, the sample dividing plate 13 divides the sample pile into the required number of portions. After the sample is divided, the sample exists independently in the sealed area formed by the sample dividing plate 13 and the side wall of the sampling bottle 1. After the corresponding opening and closing cover 12 above the area is opened, the sampling bottle 1 is turned over to complete the sampling of the sample in the corresponding sealed area. The sample is sequentially sampled to complete the division of the sample.
