Embodiment 1

[0012] Please refer to the accompanying drawings, a frame 1 whose specific structure is not limited by the figure is given, and a screen box 2 is provided on the upper part of the frame 1 through a group of (four in the figure) support feet 26, According to common sense, the screen box 2 is set on the frame 1 in a floating state by means of the support feet 26 , and is supported by the springs 261 sleeved on each of the support feet 26 . There are a pair of vibrators 3 , which are fixedly mounted on each side of the screen box 2 in the longitudinal direction corresponding to each other, and are located in the middle of the screen box 2 in the longitudinal direction. A mesh screen 21 is fixed in the box cavity of the screen box 2 along the length direction of the screen box 2, and the box cavity of the screen box 2 is divided into two parts in the height direction by the mesh screen 21, one of which is the feed cavity 22, the other is the discharge cavity 23, the feed cavity 22...

Embodiment 2

[0014] The illustration is omitted, the number of the vibrator 3 is changed to one, and it is installed in the middle part of the bottom of the screen box 2, and the rest are the same as the description of Embodiment 1.

Abstract

A vibratory sieving mechanism belongs to the technical field of vibrating device. The vibratory sieving mechanism comprises a machine frame, a sieving box that is arranged at the upper part of the machine frame, and at least one vibrator that is fixedly arranged on the sieving box. The sieving box is internally provided with a screen along the length direction of the sieving box. The cavity of the sieving box is divided into a feeding cavity and a discharging cavity by the screen, the feeding cavity is located above the screen, and the discharging cavity is located below the screen. The feeding cavity communicates with a feeding hopper at one end of the sieving box, the discharging cavity communicates with a discharging opening at the other end of the sieving box, wherein the cavity wall of the feeding cavity is also provided with an impurity discharging door for removing impurities in the feeding cavity. The advantages are that the invention can effectively remove impurities mixed in powdery products so as to guarantee the purity of the products and has high working performance.

Description

technical field [0001] The invention belongs to the technical field of vibrating devices, in particular to a vibrating material screening mechanism, which is used for screening out the sundries mixed in materials to be packaged. Background technique [0002] For some solid powdered chemical products such as pharmaceutical intermediates, impurities are not allowed in the product. Taking imidazolidine powder as a pesticide intermediate as an example, when it is divided into small packages from large packages, it is necessary to strictly control the production process. The sundries mixed in the process, such as iron pieces peeled off in the reaction kettle, enamel pieces and screws from the equipment in other processes, and woven bag scraps mixed in the previous large packaging process, etc., because if Failure to remove the above-mentioned foreign matter will bring trouble to the pesticide manufacturer, causing damage to the stirring device and the reaction kettle, for example...
