Description

Technical Field

[0001] The utility model belongs to the technical field of anti-blocking sand mills, and in particular relates to an anti-blocking screen mechanism of a sand mill. Background Art

[0002] The sand mill uses a material pump to input the solid-liquid phase mixture that has been pre-dispersed and wetted by the mixer into the cylinder, which can realize continuous processing and continuous discharge of materials, greatly improving production efficiency. Nano sand mill is suitable for dispersing various viscosity products and grinding nano-level materials, such as: nano materials, paints and printing inks, high-quality automotive paints, pigments and dyes, pesticides, papermaking, nano-level grinding, pharmaceuticals and other industries.

[0003] After the sand mill grinds the material, it flows out after being filtered through the filter plate. Because the material is moist, it is easy for the material to gather when passing through the filter plate, blocking the filter plate, causing the material to be unable to flow out and reducing the material discharge speed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide an anti-blocking screen mechanism for a sand mill.

[0005] To achieve the above-mentioned purpose, the utility model proposes an anti-blocking screen mechanism for a sand mill, comprising a circular cylinder, a material delivery hole is provided on the circular cylinder, a circular through groove is provided on one side of the circular cylinder, a filter plate is fixedly connected in the circular through groove, an anti-blocking component is provided on one side of the filter plate, the anti-blocking component comprises an arc plate, the arc plate is fixedly connected to the circular cylinder, the inner arc surface of the arc plate is fixedly connected to the circular plate, a cleaning plate is provided on one side of the circular plate, a puncture needle is provided on one side of the cleaning plate, and the puncture needle cooperates with the filter hole on the filter plate.

[0006] In one example, four cleaning plates are provided on one side of the circular plate, and the four cleaning plates are arranged in a circular array. The cleaning plates are fixedly connected to a round rod at the center of the circular plate, one end of the cleaning plate is against the outside of the round rod, and a pushing assembly is provided on the other side of the circular plate.

[0007] In one example, the other side of all the cleaning plates is fixedly connected to a sliding rod, which passes through the circular plate and is slidably connected to the circular plate. One end of the sliding rod is fixedly connected to a limit plate, and a spring is fixedly connected between the limit plate and the circular plate.

[0008] In one example, all of the cleaning plates are fan-shaped.

[0009] In one example, the pushing assembly includes a shell, which is fixedly connected to a circular plate, a side wall of the shell is fixedly connected to a mounting plate, one side of the mounting plate is fixedly connected to a drive motor, a main shaft of the drive motor is fixedly connected to a support plate, one side of the support plate is fixedly connected to an electric push rod, and a telescopic rod of the electric push rod is fixedly connected to the pushing plate.

[0010] In one example, one side of the circular cylinder is fixedly connected to a servo motor, a main shaft of the servo motor is fixedly connected to a rotating rod, and an outer side of the rotating rod is fixedly connected to a spiral plate.

[0011] The anti-blocking screen mechanism of a sand mill proposed by the utility model can bring the following beneficial effects:

[0012] First, by setting a puncture needle, the cleaning plate is close to the filter plate, so that the puncture needle on one side of the cleaning plate passes through the filter plate, pushing the material blocking the filter plate into the circular cylinder, leaving the filter plate, and adjusting the position to pass through the filter plate again under the push of the material in the circular cylinder, so as to avoid the filter plate being blocked and affecting the outflow of the material;

Each time the pushing component pushes a cleaning plate close to the filter plate for processing, only one-fourth of the area is blocked, and the material in other areas continues to be discharged. Then, other cleaning plates are pushed in turn, so that when the filter plate is processed, the material flow will not be hindered. BRIEF DESCRIPTION OF THE DRAWINGS
