Description

Broken product screening plant is used in laboratory Technical Field The application relates to the technical field of mineral separation laboratory equipment, in particular to a broken product screening device for a laboratory. Background When laboratory analysis and detection and flotation tests are performed on samples such as mineral samples, the crushed samples often need to be screened to achieve the required granularity of laboratory ore grinding equipment. The traditional screening mode is characterized in that a large fixed screening device is used according to the requirements of samples, but in a laboratory, the operation space is limited, the occupied area of the device is large, the screening operation is complex, the screening efficiency of small batches of samples is low, and the manual screening is adopted, but the labor intensity is high, the screening efficiency is low, and the consistency of the screening effect is difficult to ensure. Therefore, a small-sized screening instrument which is easy to operate and efficient is needed to meet the requirements of a laboratory for rapid and accurate screening of crushed samples. Disclosure of utility model In order to solve or partially solve the problems in the related art, the application provides a crushed product screening device for a laboratory, which can rapidly and accurately screen crushed samples in the laboratory. The application discloses a crushed product screening device for a laboratory, which comprises: A mesh screen, wherein guard plates are arranged around the outer side of the mesh screen; the adjustable upright post can be used for adjusting the height in a telescopic way; A rotating shaft, a rotating shaft seat; Wherein, connect in both sides of both sides backplate and set up four pivots, pivot switching sets up on the pivot seat, pivot seat fixed connection sets up the top at adjustable stand. Optionally, a handrail is arranged on one side of the mesh screen. Optionally, the top of the two side guard plates in the radial direction of the rotating shaft is obliquely provided with a baffle. Optionally, the adjustable upright post comprises a supporting plate, a screw, a telescopic post, a spring and an upright post; Wherein, the stand sets up to two sections, uses spring fixed connection in the middle, top and pivot seat fixed connection, and the bottom is flexible post, and the lateral part of flexible post is provided with the screw that the altitude mixture control was fixed, and flexible post bottom height is provided with the backup pad. Optionally, the telescopic column comprises a fixed sleeve and a movable column slidingly connected in the fixed sleeve, a screw is arranged on the fixed sleeve in a threaded connection mode, a key groove is arranged on the movable column, and the screw is in butt joint with the bottom of the key groove. Alternatively, the mesh of the mesh screen is two millimeters, the mesh screen being fifty centimeters long and twenty-five centimeters wide. The technical scheme provided by the application can comprise the following beneficial effects: The device has the advantages of being small in overall size and size, being 50 cm long and 25 cm wide, being small in occupied space, being convenient to place and use on a laboratory operation table, being particularly suitable for screening small batches of samples, being convenient for throwing back materials in the screening process, preventing samples from splashing, guaranteeing the integrity of the screening process and the recovery rate of the samples by arranging the guard plates and the baffle plates in the screening direction, being capable of simplifying the structure of screening front and back by utilizing the elastic characteristic of the spring, reducing the complexity of the device by only pulling the handrail to screen front and back, facilitating the screening operation, improving the screening efficiency, being designed according to actual requirements by the screen hole size, having good screening effect on common laboratory crushed samples, being capable of accurately screening samples meeting the granularity requirement, and improving the accuracy and reliability of a test.
