Abstract
The invention provides the compass screen surface percussion device technology art scheme of a kind of Cantilevered screen, the program includes the compass screen surface being made up of multiple cross-arms being fixed with multiple Suspension arm sieve side by side rod, this compass screen surface is fixed between two side plates the Cantilevered screen formed, this programme is that described each sieve rod is fixed with connecting plate in bottom surface, sieve rod middle part separately, described each connecting plate is fixed on again in the vibrating tube of strip, is placed with the diameter vibrator bar less than vibrating tube internal diameter in this vibrating tube.This structure of this programme, makes sieve rod both can produce secondary vibration and has anti-blocking effect, in turn ensure that screening efficiency and the screening precision of screen cloth.
Description
Technical field
The present invention relates to a kind of industrial screening plant, the compass screen surface percussion device of a kind of Cantilevered screen.
Background technology
In the prior art, known technology be the percussion device of anti-blocking screen cloth, modal device is to fix vibrator bar at biside plate, equipped with taping block on this vibrator bar, taping block on this structure operationally vibrator bar hits sieve rod, make sieve rod produce secondary vibration, rejecting can be vibrated be clamped between two sieve rods by sieve material, reach to prevent the purpose of blocking.But the direction of vibration of sieve rod secondary vibration is polynary, can there is the vibration of vertical compass screen surface, can also there is the vibration of the most parallel compass screen surface of out of plumb, the vibration of this out of plumb compass screen surface directly affects the percent opening of screen cloth and the screening precision of sieve aperture, the screening efficiency and the screening precision that make screen cloth are difficult to improve, and this is the weak point existing for prior art.
Summary of the invention
The technical problem to be solved is aiming at the deficiency existing for prior art, and the compass screen surface percussion device technical scheme of a kind of Cantilevered screen is provided, the program uses the bottom surface fixed connecting plate at interval sieve rod, and be fixed on connecting plate in vibrating tube, vibrator bar it is placed with in vibrating tube, operationally, vibrator bar hits the tube wall of vibrating tube in vibrating tube, vibrating tube is made to drive sieve rod to produce secondary vibration, the vibration formed in vibrating tube due to vibrator bar can only make connecting plate be the vibration of vertical compass screen surface, and sieve rod and be fixed on connecting plate, therefore sieve rod also can only be vibrated by vertical compass screen surface, ensure that the screening precision of screen cloth.
This programme is achieved by the following technical measures: the compass screen surface percussion device of the Cantilevered screen of this programme, including the compass screen surface being made up of multiple cross-arms being fixed with multiple Suspension arm sieve side by side rod, this compass screen surface is fixed between two side plates the Cantilevered screen formed, the feature of this programme is that described each sieve rod is fixed with connecting plate in bottom surface, sieve rod middle part separately, described each connecting plate is fixed on again in the vibrating tube of strip, is placed with the diameter vibrator bar less than vibrating tube internal diameter in this vibrating tube.The concrete feature of this programme also has, and described vibrating tube is one or coaxial two or more.The cross section of described vibrating tube internal vibration bar is circular.The cross section of described vibrating tube internal vibration bar is annular.The material of described vibrating tube internal vibration bar is metal material.The material of described vibrating tube internal vibration bar is nonmetallic materials.
The beneficial effect of this programme can be learnt according to the narration of such scheme, owing to the bottom surface of sieve rod middle part, interval in this scenario is fixed with connecting plate, described each connecting plate is fixed on again in the vibrating tube of strip, is placed with the diameter vibrator bar less than vibrating tube internal diameter in this vibrating tube.This structure, operationally, vibrator bar hits the tube wall of vibrating tube in vibrating tube, vibrating tube is made to drive sieve rod to produce secondary vibration, the vibration formed in vibrating tube due to vibrator bar makes connecting plate can only produce the vibration of vertical compass screen surface, and sieve rod and be fixed on connecting plate, therefore sieve rod also can only be vibrated by vertical compass screen surface, the vibration of out of plumb compass screen surface can not be produced, therefore the length that can lengthen sieve rod improves percent opening, and ensure that the percent opening of screen cloth and the dimensional accuracy of sieve aperture, therefore, sieve rod both can produce secondary vibration and have anti-blocking effect, in turn ensure that screening efficiency and the screening precision of screen cloth, as can be seen here, the present invention is compared with prior art, there is prominent substantive distinguishing features and significantly progress, its beneficial effect implemented also is apparent from.
Accompanying drawing illustrates:
Fig. 1 is the partial cross structural representation of the specific embodiment of the invention.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the A portion enlarged diagram of Fig. 1.
In figure, 1 is side plate, and 2 is cross-arm, and 3 is sieve rod, and 4 is connecting plate, and 5 is vibrator bar, and 6 is vibrating tube.
Detailed description of the invention:
For the technical characterstic of this programme can be clearly described, below by a detailed description of the invention, and combine its accompanying drawing, this programme is illustrated.
Be can be seen that by accompanying drawing, the compass screen surface percussion device of the Cantilevered screen of this programme, including the compass screen surface being made up of multiple cross-arms 2 being fixed with multiple rod of Suspension arm sieve side by side 3, this compass screen surface is fixed between two side plates 1 Cantilevered screen formed, and this programme is that described each sieve rod 3 is fixed with connecting plate 4 in sieve rod 3 bottom surfaces, middle part separately.Described each connecting plate 4 is fixed in the vibrating tube 6 of strip, and it can also be coaxial two or more that this vibrating tube 6 can be one, can be according to the width of screen cloth depending on, this detailed description of the invention uses a vibrating tube 6.Diameter it is placed with less than the vibrator bar 5 of vibrating tube 6 internal diameter, depending on the diameter of this vibrator bar 5 can be according to hitting the needs of quantity to vibrating tube 6 in described vibrating tube 6.The cross section of described vibrating tube 6 internal vibration bar 5 can be circular or annular, and this detailed description of the invention uses the vibrator bar 5 of circular cross section.The material of described vibrating tube 6 internal vibration bar 5 can be metal material or nonmetallic materials, and this detailed description of the invention uses the vibrator bar 5 of metal material.
