Description

A kind of new-type rolling sieve

Technical field

The present invention relates to the process units in the ceramic industry, particularly a kind of new-type rolling sieve.

Background technology

In the prior art, ceramic is so that its density is high, contraction distortion is little, wearability good, decorative effect preferably, and becomes the object of customer selecting, has vast market.The raw material production procedure is the important step of Ceramic Production in its production process; This link not only is related to the quality of end product quality; The problem such as cost, service life that also is related to product is so The Gift of Being the Best You Can Be is all made every effort to by each enterprise on this link, from the innovation that controls to the tool of production of technology; Dropped into a large amount of research and development strengths, to strengthen competitiveness of product.Traditional spray art use sieve is straight sieve, and product from the straight sieve of spray tower mouth entering vibration, by the straight sieve vibration of driven by motor, is sent the powder filtration into hopper with powder, and underproof meal material then goes out screen cloth by the labor cleaning.This structure is the universal way of filtering powder in the prior art, and temporarily acomia existing other modes are filtered powder.This structure often causes the obstruction of sieve aperture, and the powder that causes reclaiming is many, and the powder that gets into feed bin is inhomogeneous, does not reach production requirement, and product percent of pass is low; And the straight sieve of this vibration, must be by underproof meal material on labor cleaning's screen cloth, labour intensity is quite big, and labor productivity is low; And more serious be, the screen cloth rapid wear, abrasive forces is bigger, is merely service life about 5 hours.This structural vibrations sieve maintaining expense is higher, and energy consumption is bigger, causes cost higher, and these problems are perplexing the development of ceramic industry always, become each enterprise and reduce cost, a big obstacle that enhances the competitiveness.

Summary of the invention

The objective of the invention is to overcome the defective of prior art, provide a kind of powder that gets into feed bin evenly, powder can often not stop up sieve aperture, can alleviate labor strength, raise labour productivity, improve the quality of products, reduce production costs, prolong the screen cloth new-type rolling sieve in service life.

The objective of the invention is to realize through following technical scheme:

A kind of new-type rolling sieve comprises the motor, the screen cloth that are connected, and said screen cloth is the class cylinder of end sealing, and said screen cloth is provided with at least three thick material back-up ring.

Said motor is located on the central shaft of back-up ring.

Said screen cloth port diameter is greater than base diameter.

The bottom surface of said screen cloth and horizontal plane are 10 ° at least.

The low side of said screen cloth is provided with drawing mechanism.

Said screen cloth bottom is provided with the powder conveyer belt.

The powder discharging opening of said drawing mechanism is corresponding with conveyer belt.

After the present invention adopts technique scheme, can reach following beneficial effect:

1, rational in infrastructure.The present invention has overcome prior art screen cloth mesh and has often stopped up; Cause the meal material of recovery many; The powder that gets into feed bin is inhomogeneous; Productivity ratio is low; The raw material qualification rate is low, and the defective of unreasonable structure adopts the roller screen cloth, has overcome all defectives of prior art, has improved labor productivity, and is rational in infrastructure.

2, powder quality is good.The present invention makes the powder that gets into feed bin more even because of rational in infrastructure.

3, operation rate of machinery is high.The present invention is in application process, because screen cloth is the vibration of rolling, powder can not resemble frequent obstruction sieve aperture the prior art, needn't often shut down cleaning, so operation rate of machinery is high.

4, environmental protection.The present invention reduces the energy consumption in the unit interval, must labor cleaning's meal material, and its All Jobs is accomplished by machinery, has reduced working strength of workers, and site environment is better, adapts to the requirement of current social enviroment protection.

5, prolonged service life.Screen cloth of the present invention has reduced mechanical loss because type of being is cylindrical, not easy to wear, and prolonged the service life of screen cloth, can practice thrift about 120,000 yuan of maintenance cost every year.

6, reduced cost.The present invention has done the improvement of science on the basis of existing technology, need not to increase too many cost, but can improve ceramic products output about 25%, and screen life-span prolongs about 60%, has reduced cost.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is done further explain:

Referring to Fig. 1

Fig. 1 is the prior art constructions sketch map.In Fig. 1, powder is dropped down onto on the screen cloth 1 by the outlet 51 of spray tower mouth 5, and said screen cloth 1 is a class cuboid low between the senior middle school of both sides; Screen cloth 1 is driven by motor 2, and the bottom of screen cloth 1 is provided with glue rod 4 as vibration source, and said glue rod 4 is at least 4; And the eccentric shaft 3 that motor 2 tops are provided with is in transmission connection with motor 2, glue rod 4, and keeps screen cloth 1 to be a fore-and-aft tilt shape, and qualified powder directly falls into the hopper 6 that screen cloth 1 bottom is provided with by screen cloth 1; Screen cloth 1 is provided with meal material outlet 7 apart from the far-end of eccentric shaft 3; Ccontaining for the meal material, the screen cloth of this structure (vibration is sieve directly) is the screen cloth that present ceramic industry generally uses, and mechanical loss is big; Just must change screen cloth in about about 5 hours, cost is higher.Its underproof meal material often stops up mesh, causes the meal material of recovery many, and the powder that gets into feed bin is inhomogeneous, and must be through labor cleaning's meal material, because the field operation dust pollution is bigger, so labour intensity is big.

Referring to Fig. 2

Fig. 2 is a structural representation of the present invention.In Fig. 2, the screen cloth 1 among the present invention is the class cylinder of bottom lock, and its port diameter is greater than base diameter; Screen cloth 1 is provided with three thick material back-up ring 8 at least, and in order to the coarse granule in the mesh support screen 1 and the powder of blocking, screen cloth 1 is the state that an inclination angle is at least 10 °; And the outlet 51 of spray tower mouth 5 high-end corresponding to screen cloth 1, and the low side of screen cloth 1 is located in the outlet 91 of the transport 9 of qualified powder, because of the vibration rolling structure of screen cloth 1; Qualified powder meeting nature is come out by the low side of screen cloth 1 after operation is handled, and transports to qualified powder transport 9, is sent into by the outlet 91 of qualified powder on the conveyer belt 10 of screen cloth 1 bottom setting; The meal material rests on the bottom of screen cloth 1 low side, when for clearance then because of the gravity effect; Screen cloth is inverted, simple and convenient; Reduced working strength of workers, and motor 2 is located on the central shaft of thick of screen cloth 1 material back-up ring 8, has reduced mechanical wear to greatest extent, and can improve rotating speed, making changes scooter 15r/m, has improved the qualification rate of powder greatly.The present invention also is equipped with wheel in the bottom, makes things convenient for moving of device.

The present invention makes the qualified powder that gets into feed bin even, and the rate of recovery of meal material is low, and powder transports conveniently, and the screen cloth long service life just needed to change, and greatly reduced cost in about about two months.
