Description

Technical Field

[0001] This application relates to the field of mineral processing laboratory equipment technology, and in particular to a laboratory crushing product screening device. Background Technology

[0002] In laboratory analysis and flotation tests of mineral samples, it is often necessary to screen the crushed samples to achieve the particle size required by laboratory grinding equipment. Traditional screening methods, depending on the sample requirements, include either using large, fixed screening equipment, which is inefficient in laboratory settings due to limited operating space, large equipment footprint, and cumbersome operation, resulting in low efficiency for small batches of samples; or manual screening, which is labor-intensive, inefficient, and yields inconsistent screening results. Therefore, a simple, efficient, small-scale screening instrument is needed to meet the laboratory's need for rapid and accurate screening of crushed samples. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides a laboratory crushed product screening device that can quickly and accurately screen crushed samples in the laboratory.

[0004] This application discloses a laboratory crushed product screening device, comprising:

[0005] A wire mesh screen, wherein a protective plate is provided around the outer perimeter of the wire mesh screen;

[0006] An adjustable column, wherein the adjustable column can be extended and retracted to adjust its height;

[0007] Shaft, shaft seat;

[0008] Four rotating shafts are connected to both sides of the side guard plates. The rotating shafts are mounted on rotating shaft seats, which are fixedly connected to the top of the adjustable column.

[0009] Optionally, a handrail is provided on one side of the screen.

[0010] Optionally, baffles are inclinedly provided on the top of the two side guards in the radial direction of the shaft.

[0011] Optional, the adjustable column includes a support plate, screws, telescopic column, spring and column;

[0012] The column is divided into two sections, which are fixedly connected in the middle by a spring. The top is fixedly connected to the pivot seat, and the bottom is a telescopic column. The side of the telescopic column is equipped with a height adjustment screw, and a support plate is provided at the bottom of the telescopic column.

[0013] Optionally, the telescopic column consists of a fixed sleeve and a movable column that slides inside the fixed sleeve. A screw is threaded onto the fixed sleeve, and a keyway is provided on the movable column, with the screw abutting against the bottom of the keyway.

[0014] Optionally, the mesh size of the screen is two millimeters, and the screen is fifty centimeters long and twenty-five centimeters wide.

[0015] The technical solution provided in this application may include the following beneficial effects:

[0016] This device features a simple structural design. Firstly, its compact size (50 cm long and 25 cm wide) minimizes space requirements, making it easy to place and use on a laboratory workbench, especially suitable for screening small batches of samples. Secondly, the inclusion of guard plates and baffles in the screening direction facilitates material return during screening, preventing sample splashing and ensuring the integrity of the screening process and high sample recovery rate. Thirdly, the use of springs simplifies the forward and backward screening mechanism; simply pulling the handle moves the device, reducing complexity, facilitating operation, and improving efficiency. The sieve aperture size can be customized to meet specific requirements, providing excellent screening results for common laboratory crushed samples, accurately identifying samples that meet particle size requirements, and enhancing the accuracy and reliability of experiments.

[0026] To address the aforementioned problems, this application provides a laboratory crushed product screening device. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 A laboratory crushed product screening device is shown, comprising:

[0028] The screen 2 is generally rectangular, 50 cm long and 25 cm wide, with a mesh size of 2 mm. A protective plate 1 surrounds the outside of the screen 2 to prevent sample splashing during sieving, ensuring effective sieving within the sieving area. Four rotating shafts 3 are connected to both sides of the protective plates 1, and are rotatably mounted on rotating shaft seats 31. The rotating shaft seats 31 are fixedly connected to the top of an adjustable column, which can extend and retract to adjust its height and tilt angle to accommodate different sieving needs. A handrail 12 is provided on one side of the screen 2 for easy operation by the operator. The handrail 12 is located on one of the protective plates 1 in the radial direction of the rotating shafts 3.

[0029] In one embodiment, baffles 11 are inclinedly provided on the top of the two side guard plates 1 in the radial direction of the rotating shaft 3, so as to facilitate the throwing back of materials during the screening process.

[0030] In one embodiment, the adjustable column includes a support plate 44, a screw 43, a telescopic column 42, a spring 41, and a column 4;

[0031] The column 4 is divided into two sections, with the middle section fixedly connected by a spring 41. The top section is fixedly connected to the pivot seat 31, and the bottom section is a telescopic column 42. The telescopic column 42 consists of a fixed sleeve and a movable column that slides inside the fixed sleeve. A screw 43 is threadedly connected to the fixed sleeve, and a keyway is provided on the movable column. The screw 43 abuts against the bottom of the keyway. A support plate 44 is provided at the bottom of the telescopic column 42 for easy support.

[0032] When using the equipment, adjust the height and angle beforehand, screw in the screw 43 to fix the telescopic column 42, and pull the handrail 12 back and forth to form a rocking chair-like operation for screening. Through the elasticity of the spring 41 itself, the upper part of the spring 41 can be pulled and shaken, thereby completing the screening.

[0033] This application employs a simple structural design. Firstly, the overall size and volume of the equipment are compact, measuring only 50 cm in length and 25 cm in width, occupying minimal space and facilitating placement and use on a laboratory workbench, making it particularly suitable for screening small batches of samples. Secondly, by incorporating a protective plate 1 and a baffle 11 in the screening direction, the equipment facilitates material return during screening, preventing sample splashing and ensuring the integrity of the screening process and sample recovery rate. Thirdly, utilizing the elastic properties of the springs simplifies the forward and backward screening structure; simply pulling the handle initiates the screening, reducing equipment complexity, facilitating screening operations, and improving screening efficiency. The sieve aperture size can be designed according to actual requirements, providing excellent screening results for common laboratory crushed samples, accurately selecting samples that meet particle size requirements, and improving the accuracy and reliability of the experiment.

[0034] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
