Abstract
The utility model discloses a strip-type air bag for a vibrating screen. The strip-type air bag for the vibrating screen comprises an air bag body. An air nozzle is arranged on the air bag body which is in a long strip shape. Strip-type support strips are arranged on the upper surface of the air bag body along the length direction of the air bag body. The cross section of the air bag body is in a flat shape. The strip-type air bag is placed into a vibrating support groove of the vibrating screen and is fixed, a pressing plate is further placed on the air bag, and a screen is placed on the pressing plate, so the air bag can push the pressing plate to tightly press the screen after the air bag is inflated, and then the air bag can normally work. When the screen is replaced, air pressure is discharged, the air bag is contracted to a normal position, and the screen can be smoothly pulled out to finish the replacing operation of the screen. The replacing operation is simple, fast, labor-saving and time-saving, and efficiency of replacing the screen is greatly improved.
Description
Technical field:
The utility model relates to a kind of material vibrating screening and grading machinery equipment, particularly relates to a kind of used by oscillating screen strip shaped air sac.
Background technology:
Vibratory sieve is applied to many fields at present, as: the industries such as mine, coal, metallurgy, iron and steel, papermaking, oil field, vibratory sieve is comprised of members such as vibration rack, pressing plate, screen clothes.But the screen cloth that vibratory sieve uses is according to job requirement, need often to change the different meshes screen cloth, the dismounting screen cloth has become complexity and hard work, vibratory sieve institute environment for use inclement condition, condition is narrow, adding the replacing screen cloth needs fastening more than 30 screws, thereby this work is made the matter worse especially.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of used by oscillating screen strip shaped air sac that designs uniqueness, easy to use, high efficiency and reduce labour intensity is provided.
The technical solution of the utility model is:
A kind of used by oscillating screen strip shaped air sac contains pneumatophore, is provided with valve on described pneumatophore, and described pneumatophore is strip, and, along being provided with the strip support bar on the upper surface of described pneumatophore length direction.
The cross section of described pneumatophore is flat.
The cross section of described support bar is inverted trapezoidal, rectangle or square.
Described pneumatophore is composited by outer glue-line, casing play and inner glue layer.
The beneficial effects of the utility model are:
1, it is fixing that the utility model is put into the vibration rack groove of vibratory sieve, and the above puts pressing plate again, puts screen cloth above pressing plate, and after airbag aeration, air bag promotes pressing plate and compresses screen cloth, then just can work.When changing screen cloth, shed air pressure, air bag retracts to original position, and screen cloth just can be pulled out smoothly, and complete screen cloth and more change jobs, simple and fast, saving of work and time greatly improves and changes screen cloth efficient.
2, the utility model pneumatophore adopts flat, has increased lifting surface area, has strengthened the thrust of air bag, better fixes screen cloth.
3, the utility model support bar is the inverted trapezoidal shape, and the upper end contact area is large, and pressure is uniform and stable, improves the effect that is fixed of screen cloth.
4, unique, easy to use, the high efficiency of the utility model design and reduction labour intensity, be easy to promotion and implementation, and economic benefit is good.
Description of drawings:
Fig. 1 is the structural representation of used by oscillating screen strip shaped air sac;
Fig. 2 is A-A cutaway view in Fig. 1;
Fig. 3 is B-B cutaway view in Fig. 1.
The specific embodiment:
Embodiment: referring to Fig. 1-Fig. 3, in figure, 1-support bar, 2-pneumatophore, 3-valve, 4-inner glue layer, 5-casing play.
The used by oscillating screen strip shaped air sac contains pneumatophore 2, is provided with valve 3 on pneumatophore 2, and wherein: pneumatophore 2 is strip, and, along being provided with strip support bar 1 on the upper surface of pneumatophore 2 length directions.
The cross section of pneumatophore 2 is flat.The cross section of support bar 1 is inverted trapezoidal, rectangle or square, determines as required.Pneumatophore 2 is composited by outer glue-line, casing play 5 and inner glue layer 4.
During use, the utility model is put into the vibration rack groove of vibratory sieve and is fixed, and the above puts pressing plate again, puts screen cloth above pressing plate, and after airbag aeration, air bag promotes pressing plate and compresses screen cloth, then just can work.When changing screen cloth, shed air pressure, air bag retracts to original position, and screen cloth just can be pulled out smoothly, and complete screen cloth and more change jobs, simple and fast, saving of work and time greatly improves and changes screen cloth efficient.
The above is only preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction, and every any brief modification of doing according to the utility model all still belongs to protection domain of the present utility model.
Claims (4)
1. a used by oscillating screen strip shaped air sac, contain pneumatophore, is provided with valve on described pneumatophore, it is characterized in that: described pneumatophore is strip, and, along being provided with the strip support bar on the upper surface of described pneumatophore length direction.
