Description

Technical Field

[0001] The utility model belongs to the technical field of limestone powder screening, in particular to a vibrating screening machine for limestone powder production. Background Art

[0002] Limestone powder is a kind of calcium carbonate material, generally in the form of white powder. It is divided into heavy calcium carbonate and light calcium carbonate, mainly used in the construction industry, and can also be used as a filler for plastics, paper, toothpaste and other materials. In order to improve production efficiency and meet the needs of subsequent processing and use, the powder of limestone is often screened after being crushed;

[0003] At present, in the process of screening after lime water is crushed, it is found that although the vibration screening method can remove large particles, a certain amount of limestone powder will adhere to the surface of the large particles, resulting in the loss of limestone powder, increasing cost output, and also affecting the production and processing efficiency of limestone powder;

[0004] In order to solve the above problems, the present application proposes a vibrating screening machine for limestone powder production. Utility Model Content

[0008] Furthermore, a storage box is provided at the lower end of the screening machine, a guide frame is provided at the lower end of the screening frame to connect to the storage box, and an inner plate frame is provided on the inner side of the lower end of the guide frame to be installed inside the upper end opening of the storage box.

[0009] Furthermore, a ring sleeve is provided at the lower end of the paddle plate, the ring sleeves at the lower ends of adjacent paddle plates are staggered, and adjacent paddle plates form a group, and the ring sleeves at the lower ends are rotatably mounted on the outer side of the rotating shaft at the lower end of the fixing frame.

[0010] Furthermore, a positioning rod is also provided at the lower end of the fixing frame to block the shift plate to fix its downward rotation angle.

[0012] Furthermore, a folding portion is provided at the upper end of the sleeve frame and is connected to a bottom plate mechanism of the guide frame.

[0013] Furthermore, the telescopic structure of the folding portion is used to avoid affecting the storage box when the screening frame vibrates up and down.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can push out the paddle plate when the large particle impurities are vibrated and fly up by adding a fixing frame, so that the impurities fall between the adjacent paddle plates and cannot fall back, thereby directly separating the large particle impurities from the limestone powder, accelerating the screening efficiency, and avoiding the accumulation of a large amount of impurities affecting the screening effect;

[0027] See also Figure 1-4 As shown, the utility model is a vibrating screening machine for limestone powder production, comprising: a screening machine 1 and a screening frame 2 inside thereof, wherein the inside of the screening frame 2 is a screen mechanism;

[0028] One end of the screening machine 1 is provided with an auxiliary box 3 for storing large particles of impurities, and both ends of the auxiliary box 3 are provided with side boxes 4 for storing limestone powder attached to large particles of impurities, and a suction mechanism for sucking limestone powder is provided on the outside of the side box 4.

The fixing frame 8 is connected to the top seat mechanism of the screening machine 1 through an electric telescopic mechanism at its upper end to drive the adjacent paddles 6 to vibrate up and down. The adjacent paddles 6 are arranged in a V-shaped structure.

[0030] This embodiment provides a separation and secondary screening structure for limestone powder screening. The V-shaped distribution mechanism of the paddle 6 can block the continuous falling of large particles of impurities, forming a separation effect. In the subsequent collection process, the side box 4 and the suction mechanism on its outside are used to form a secondary screening effect on the large particles of impurities, so that the limestone powder on its surface is extracted and stored.

[0031] Among them, a storage box 5 is provided at the lower end of the screening machine 1, and a guide frame 7 is provided at the lower end of the screening frame 2 to dock with the storage box 5.

The paddle plate 6 is in an inclined placement state, which is used to guide the large particles of impurities to the lower end position after separation, so as to facilitate secondary screening operations.
