Description

Vibrating sieve for ceramic powder

technical field

The utility model relates to the technical field of ceramic material production equipment, in particular to a spare vibrating sieve for ceramic powder.

Background technique

Ceramic materials refer to a class of inorganic non-metallic materials made of natural or synthetic compounds after forming and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance, and oxidation resistance. It can be used as structural material and tool material. Since ceramics also have some special properties, they can also be used as functional materials. Ceramic powder has most of the properties of ceramic materials and is widely used in coatings to improve the performance of coatings.

In the process of preparing ceramic powder, it is necessary to grind corundum, silicon carbide, etc. into powder, and then screen the powdery corundum, silicon carbide, etc., but the vibrating screen used for ceramic powder in the prior art has slow screening speed and low efficiency. When working, powdery raw materials are generally only filtered in the middle of the filter screen, and the effective use area ratio of the filter screen is small, which not only causes slow filtration speed and low efficiency, but also makes the middle part of the filter screen age too quickly, reducing the efficiency of the filter screen. service life, so it needs to be improved.

The crankshaft drives the fixed frame to sieve, with simple structure and high operating efficiency. The side of the screening box opposite to the drive unit is provided with a slag outlet that matches the fixed frame to facilitate timely discharge of filter slag.

Further, the two sides of the screening box are provided with chute, the fixed frame is slidably arranged in the chute, the lower surface of the fixed frame is provided with a ball groove, and balls are slidably arranged in the ball groove, and the ball is rollingly matched with the bottom surface of the chute. .

Further, the screening box is arranged obliquely to the horizontal plane, and the inclination angle between the screening box and the horizontal plane is eight degrees to fifteen degrees, which not only facilitates the uniform distribution of materials on the filter screen, but also facilitates the discharge of unqualified raw materials from the slag outlet.

Furthermore, a baffle is provided on the upper surface of the fixed frame, and the baffle is provided on the fixed frame to prevent raw materials from falling outside the filter screen.

Further, there are at least two fixed frames up and down correspondingly, and the aperture of the filter screen on the upper fixed frame is larger than the aperture of the filter screen on the lower fixed frame, which can filter the raw materials in layers, thereby improving the filtration efficiency.

Further, the slag outlet is provided with a deflector matched with the fixed frame, one end of the deflector is arranged under the fixed frame, and the other end is connected to a filter residue collection box.

Further, a funnel-shaped hopper is provided on the feed inlet, and the hopper is convenient for adding raw materials. A connecting rod is arranged under the hopper, and a splitter is arranged under the connecting rod, and the splitter can evenly disperse the raw materials on the filter screen.

Further, a finished product box is correspondingly arranged below the discharge port, so as to facilitate the collection of qualified raw materials after screening.

The utility model pours the raw materials that need to be filtered into the hopper, and the raw materials fall on the shunt along the hopper, and the raw materials are dispersed under the action of the shunt, so that the raw materials are evenly distributed in different places above the filter net, and the raw materials are prevented from concentrating on the shunt. The middle part of the filter net improves the utilization rate of the filter net. Then the motor is energized to rotate, and the output shaft of the motor drives the crankshaft to rotate. Since the crank pin on the crankshaft is slidingly connected with the inner surface of the connecting groove, the crankshaft drives the fixed frame to reciprocate left and right on the inner surface of the chute, and the fixed frame drives the filter screen Make left and right reciprocating motions, thereby driving the raw materials on the filter to reciprocate. Furthermore, it is possible to disperse piles of raw materials to various places of the filter screen, further improving the utilization rate of the filter screen. Under the filter close to the upper filter, the unqualified raw materials will fall into the inside of the filter residue collection box under the guidance of the drainage plate, and the filtered raw materials will fall on the lower filter for further filtration, and finally the qualified raw materials will be screened out. , so as to achieve a reasonable use of the filtering area of the filter.
