Abstract
The present invention relates to a kind of can either the slow release sand material direct impact to screen cloth effectively, again can the square more rapid fixed linear vibrating screen of large-scale dry-method sand manufacturing changing breakage portion screen cloth, it includes fixing linear vibrating screen, spacing between upper sieve and the lower screen of described fixing linear vibrating screen is more than 80cm, and the composition structure of upper sieve and lower screen is sandwich modular three-deck vibrating screen.Advantage: one is that fixed linear vibrating screen is designed to two layers of mesh structure by three layer of three mesh structure, when fundamentally solving lower screen replacement cost, take a lot of work, be difficult to the defect changed, operator are made can directly to carry out the screen cloth face being replaced, achieve and both save replacing construction, be easy to again quick-replaceable;Two be the design of modular vibrosieve, it is only necessary to changes and damages screen portion, it is not necessary to change whole screen cloth, reduce the use cost of screen cloth, it is to avoid the wasting of resources.
Description
Technical field
The present invention relates to a kind of can either the slow release sand material direct impact to screen cloth effectively, again can the square more rapid fixed linear vibrating screen of large-scale dry-method sand manufacturing changing breakage portion screen cloth, belong to dry-method sand manufacturing and sieve fixed linear vibrating screen manufacture field.
Background technology
CN203292063U, title " a kind of linear vibrating screen ", including screen frame (unit), sieve nest, connected by spring between sieve nest and screen frame (unit), it is characterized in that: the top board of described sieve nest is provided with charging aperture, the first punched-plate it is provided with in sieve nest, second punched-plate, the base plate of sieve nest is provided with the fixing seat of symmetry, the second punched-plate is fixedly mounted on fixing seat, spacing between second punched-plate and the first punched-plate is fixed by adjusting bolt and adjusts, wall box is provided with big Pellet exit, non-defective unit material exports, small pellets exports, big Pellet exit is located between the top board of sieve nest and the first punched-plate, the outlet of non-defective unit material is located between the first punched-plate and the second punched-plate, small pellets outlet is located between the second punched-plate and the base plate of sieve nest.Its weak point: the first punched-plate, the second punched-plate use steel plate boring to substitute screen cloth, do not simply fail to guarantee steel plate deflection after boring, and due between Kong Yukong spacing big, the percent of pass not only causing Lou sieve reduces, sieve plate is easily formed accumulation and the bridging of sand material, causes the screening of sand cannot be carried out.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of can either the slow release sand material direct impact to screen cloth effectively, again can the square more rapid fixed linear vibrating screen of large-scale dry-method sand manufacturing changing breakage portion screen cloth.
Design: in order to realize above-mentioned purpose of design.The screen cloth of fixing linear vibrating screen is designed to the design of three layers of sandwich module screen cloth, is the technical characteristics of the present invention.So purpose of design is: owing to sandwich module screen cloth is vibrated punishment in advance pore pressure plate by upper strata, intermediate module screen cloth, lower floor's vibration punishment in advance pore pressure plate is constituted, i.e. this sandwich module screen cloth takes upper and lower double layer of metal or wear-resisting nonmetal vibration punishment in advance orifice plate does skeleton, middle clamping is shaked out and is needed the standard screen cloth of mesh number, and the screen cloth group of a cavity clearing room function containing rubber hoodle it is provided with in lower floor, owing to vibration punishment in advance orifice plate is rigidity sieve plate or the making of wear-resisting nonmetal vibration punishment in advance orifice plate material, it can not only hold by sieve sand material falling impacts power, and greatly can be sieved the sand material impulsive force to screen cloth by slow release, greatly extend the service life of screen cloth;Secondly, when screen cloth is damaged, owing to screen cloth is module type screen mesh in structure design, thus can either quick-replaceable, reduce again screen cloth consuming cost.
Technical scheme: a kind of fixed linear vibrating screen of large-scale dry-method sand manufacturing, including fixing linear vibrating screen, spacing between upper sieve and the lower screen of described fixing linear vibrating screen is more than 80cm, and the composition structure of upper sieve and lower screen is sandwich modular three-deck vibrating screen.
The present invention is compared with background technology, one is that fixed linear vibrating screen is designed to two layers of mesh structure by three layer of three mesh structure, when fundamentally solving lower screen replacement cost, take a lot of work, be difficult to the defect changed, operator are made can directly to carry out the screen cloth face being replaced, achieve and both save replacing construction, be easy to again quick-replaceable;Two be the design of modular vibrosieve, it is only necessary to changes and damages screen portion, it is not necessary to change whole screen cloth, reduce the use cost of screen cloth, it is to avoid the wasting of resources.

Detailed description of the invention
Embodiment 1: 1-4 referring to the drawings.A kind of fixed linear vibrating screen of large-scale dry-method sand manufacturing, including fixing linear vibrating screen, the spacing between upper sieve 2 and the lower screen 3 of described fixing linear vibrating screen is more than 80cm, and the composition structure of upper sieve 2 and lower screen 3 is frame sandwich module screen cloth.Described frame sandwich module screen cloth vibrates punishment in advance pore pressure plate 1601 and lower floor's vibration punishment in advance pore pressure plate 1602 at the middle and upper levels and is clipped in the middle of upper strata vibration punishment in advance pore pressure plate 1601 and lower floor's vibration punishment in advance pore pressure plate 1602 for steel plate punishment in advance orifice plate and screen cloth 1603, and upper strata vibration punishment in advance pore pressure plate 1601, screen cloth 1603 and lower floor's vibration punishment in advance pore pressure plate 1602 are positioned at sieve plate frame 1604.Described upper strata vibration punishment in advance pore pressure plate 1601 and screen cloth 1603 respectively by polylith modular upper strata vibration punishment in advance pore pressure sheet frame constitute constitute with polylith module type screen mesh and modular upper strata vibration punishment in advance pore pressure plate and module type screen mesh match.
Embodiment 2: on the basis of embodiment 1, described upper strata vibration punishment in advance pore pressure plate 1601 and lower floor's vibration punishment in advance pore pressure plate 1602 are metal overlayer vibration punishment in advance pore pressure plate and metal lower layer vibration punishment in advance pore pressure plate.
Embodiment 3: on the basis of embodiment 1, described upper strata vibration punishment in advance pore pressure plate 1601 and lower floor's vibration punishment in advance pore pressure plate 1602 are nonmetal upper strata vibration punishment in advance pore pressure plate and nonmetal lower floor vibration punishment in advance pore pressure plate.
It is to be understood that: although the word that the mentality of designing of the present invention is contrasted detailed by above-described embodiment describes; but these words describe; simply the simple text of mentality of designing of the present invention is described; rather than the restriction to mentality of designing of the present invention; any combination without departing from mentality of designing of the present invention, increase or revise, each falling within protection scope of the present invention.
