Description

Technical Field

[0001] The utility model relates to the technical field of film-coated sand raw material screening, in particular to a film-coated sand raw material screening device. Background Art

[0002] At present, the feed screening device places the raw materials on the vibrating screen and screens them through the vibrating screen. However, due to the large amount of coated sand, regular shaking on the vibrating screen may cause the vibrating screen to become blocked, which will affect the efficiency of subsequent raw material screening. For this reason, we propose a coated sand raw material screening device. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a screening device for coated sand raw materials.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a coated sand raw material screening device, comprising a device body, a feed hopper and a screening mesh plate, a chassis with a two-way motor inside is installed on one side of the device body, a threaded shaft penetrating the chassis is installed on the output shaft end of the two-way motor, a first rectangular groove is opened on one side of the device body, a control plate penetrating the first rectangular groove is installed on the side of the screening mesh plate corresponding to the first rectangular groove, the interior of the control plate is threadedly connected with the threaded shaft through a reaction screw groove, a second filter plate for secondary screening of raw materials is arranged at the bottom of the screening mesh plate, an interlaced pad rod that can be inserted and matched with the filter holes of the screening mesh plate itself is installed on the surface of the second filter plate, and the second filter plate is connected and matched with the inner support of the device body through a connecting piece.

[0005] Preferably, when the two-way motor inside the chassis drives the threaded shaft to rotate, the control board cooperates with the threaded shaft through the reaction screw groove, and the screening mesh plate itself is in a reciprocating up and down screening state, and the interlaced pad rods are interlaced and cooperated with the mesh holes of the screening mesh plate itself.

[0006] Preferably, a discharge trough is provided on the other side of the device body, a feed plate for feeding unqualified raw materials is installed on one side of the downwardly inclined bottom of the screening mesh plate, and a guide plate for guiding materials is installed on the other side of the device body corresponding to the position of the discharge trough.

[0007] Preferably, a second rectangular groove running through the interior of the device body is opened on one side of the device body, a rotating shaft is connected through one side of the device body, an end of the rotating shaft is driven by an external motor, and a transmission belt is sleeved on the outside of the rotating shaft and runs through the second rectangular groove and is sleeved with the external rotating shaft.

[0008] Beneficial Effects

[0009] The utility model provides a screening device for coated sand raw materials. It has the following beneficial effects:

[0010] (1) A device for screening coated sand raw materials. In this scheme, after the coated sand raw materials are put into the main body of the device through the feed hopper, they will fall on the surface of the screening mesh plate and roll downward. As the two-way motor inside the chassis starts to drive the threaded shaft to rotate, the threaded shaft is threadedly connected and cooperated with the reaction screw groove inside the control panel. As the threaded shaft rotates in two directions, the control panel can move upward and downward under the control of the threaded shaft, so that the screening mesh plate can vibrate and screen the fallen raw materials up and down. When the screening mesh plate moves downward, the filter holes inside the screening mesh plate will approach the interlaced pad rods and interlace with multiple groups of interlaced pad rods, so that the raw material particles in the blocked holes of the screening mesh plate can be pushed out by the interlaced pad rods. As the screening mesh plate vibrates back and forth up and down, the screening mesh plate can continuously interlace with the interlaced pad rods, so that the blocked materials are continuously cleaned, so that the raw materials can be normally screened and filtered, thereby achieving the effect of improving the screening efficiency of the coated sand raw materials.

[0011] (2) A coated sand raw material screening device, wherein the raw materials falling from the surface of the screening mesh plate are initially filtered through the screening mesh plate, and then the filtered raw materials are filtered for a second time through a second filter plate, and a running conveyor belt is provided at the bottom of the second filter plate. When the secondary filtered raw materials fall on the surface of the conveyor belt, the raw materials can be quickly transported to the outside of the device body through the conveyor belt for the next step, thereby achieving the effect of improving the subsequent processing efficiency of the raw materials.
