The utility model discloses in order to overcome prior art not enough, adopt and put in the processing gap at the stainless steel and make the screen cloth, screen cloth mass distribution is even, and dynamic balance adjusts convenience, swift.

Description

Centrifugal drier screen mesh

Technical Field

The utility model belongs to the technical field of the dry dehydration of detritus, concretely relates to centrifugal drier screen cloth.

Background

The centrifugal drier is used for drying and dewatering rock debris in mines, coal mines, petroleum and natural gas drilling. With the utility model discloses nearest prior art is: a screen CN202249854U of a detritus drier, especially a wedge-shaped screen device used for drilling detritus treatment, it is a technical field of petroleum drilling equipment; the screen comprises a screen lower flange and an upper flange which can be connected with a screen bracket of the rock debris drying machine, and a screen which is arranged along the circumferential direction of the screen upper flange and the screen lower flange and is surrounded by a ring. And a screen longitudinal support rib arranged along the screen generatrix direction and a screen transverse support rib arranged along the annular transverse direction of the screen are connected between the screen upper flange and the screen lower flange. The transverse support ribs of the screen are used for reinforcing the strength of the screen; the screen longitudinal support rib is used for connecting the upper and lower flanges of the screen and the screen transverse support rib. The screen is made by welding V-shaped stainless steel wires, the stainless steel wires are easy to deform during welding to cause the blockage of screen gaps, the welding workload is large, the production cost is high, and the period is long; secondly, the mass distribution of the screen cloth made of the welded V-shaped stainless steel wires is not uniform, and the dynamic balance is difficult to adjust when in use.

SUMMERY OF THE UTILITY MODEL

The utility model provides a centrifugal dryer screen to overcome the not enough of prior art.

The utility model adopts the technical proposal that: the utility model provides a centrifugal dryer screen cloth, includes lower flange and upper flange, fixedly connected with annular screen cloth between lower flange and the upper flange, annular screen cloth includes toper stainless steel bushing, and evenly distributed has the gap on the toper stainless steel bushing.

The gap is arranged along the bus direction of the conical stainless steel sleeve.

The gap is composed of an upper section, a middle section and a lower section which are evenly divided.

The outer end of the gap is V-shaped, and the inner end of the gap is rectangular.

The inner surface of the screen is provided with a wear-resistant layer.

Compared with the prior art, the utility model discloses beneficial effect who has:

1. the utility model discloses a process the gap and make the screen cloth on the stainless steel cover, screen cloth mass distribution is even, and dynamic balance adjusts convenience, swift.

2. The utility model discloses the screen cloth gap comprises upper, middle and lower three-section, has improved the rigidity of screen cloth, need not set up horizontal, vertical brace rod again, makes the screen cloth structure simpler, and the cost is lower, and weight reduction is about 3%.

3. The utility model discloses the outer end in screen cloth gap is the V type, the inner is the rectangle, and the gap width of outer peripheral face is greater than the gap width of internal surface, is difficult for blockking up in the use.

4. The utility model provides high production efficiency, reduced manufacturing cost, shortened production cycle.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings 1-3 and the detailed description thereof.

A centrifugal dryer screen comprises a lower flange 1 and an upper flange 3, wherein an annular screen 2 is fixedly connected between the lower flange 1 and the upper flange 3, the annular screen 2 comprises a conical stainless steel sleeve 2-1, and gaps 2-2 are uniformly distributed on the conical stainless steel sleeve 2-1.

Preferably, the gap 2-2 is arranged along the generatrix direction of the conical stainless steel sleeve 2-1. The gap 2-2 is composed of an upper section, a middle section and a lower section which are evenly divided. The outer end of the gap 2-2 is V-shaped, and the inner end is rectangular.

In order to increase the service life of the screen panel, the inner surface of the screen panel 2 is provided with a wear resistant layer.

The processing method of the gap 2-2 comprises the following steps: the V-shaped groove is washed out by a numerically controlled milling machine and a forming milling cutter, the thickness of the groove bottom is reserved to be 3mm, then a laser cutting process is applied to penetrate the groove bottom to form a rectangular net seam, the workload is greatly reduced, batch production can be realized, and the blockage of the screen seam cannot be caused. The size of the gap 2-2 is determined according to the requirements of the centrifugal dryer.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes made by the contents of the claims of the present invention should be included in the scope of the claims of the present invention.
