Abstract
The utility model relates to a material screening installation used in industry, in particular to a screen tightness adjusting device of a high-frequency electromagnetism vibrating screen. The screen tightness adjusting device has the technical proposals that a ratchet wheel (1), a detent (2), a screen body (4) of the vibrating screen and a screen shaft (3) of the vibration screen are included, wherein, the ratchet wheel is fixed on the screen shaft (3) of the vibrating screen; the detent (2) is fixed on the screen body (4) of the vibrating screen through a hinge shaft (6); a plurality of teeth are arranged at the outer edge of the ratchet wheel and are matched with the detent. The screen tightness of the vibrating screen is adjusted by the ratchet wheel and the detent, if the screen is tightened, the ratchet wheel is rotated, and the detent is matched with the teeth of the ratchet wheel till the tightness of the screen meets the demand; if the screen needs to be changed, the ratchet wheel is rotated reversely, the detent quits to be matched with the ratchet wheel so as to loosen the screen. The screen tightness adjusting device has the advantages that the structure is reasonable, the pocking is avoided, the screen tightness is convenient to be adjusted, the work efficiency is enhanced, etc., has simple and convenient operation, is not influenced by water in mash and bug dust, thereby being suitable for various vibrating screens.
Description
Affiliated technical field:
The utility model relates to the screen cloth elasticity adjusting device of a kind of material screening installation of industrial use, particularly high-frequency electromagnetic vibration sieve.
Background technology:
The high-frequency electromagnetic high frequency vibrating screen is widely used in every field, for example utilize aqueous medium the smart powder of iron to be screened etc., the electromagnetic high-frequency vibration sieve generally by frame, sieve nest, form for ore deposit case etc., sieve nest tilts to be placed on the frame, the top of sieve nest is provided with feed box, material by to the ore deposit case to the sieve nest feed, sieve nest comprises casing, screen cloth, vibrator etc.Existing screen cloth elasticity adjusting device generally adopts leading screw and nut to cooperate, and adjusts the elasticity of screen cloth.The problem that exists is: inefficiency is not easy to the adjustment of screen cloth elasticity.In addition, vibration sieve used after a period of time, owing to contain a large amount of moisture content and dust in the ore pulp, leading screw is easy to corrosion with nut and is in the same place, and nut can not rotate, and loses the function of adjustment, can not carry out the conciliation of screen cloth elasticity, and influence is produced and operating efficiency.
The utility model content:
The utility model purpose provides a kind of screen cloth elasticity adjusting device of high-frequency electromagnetic vibration sieve, is not afraid of corrosion, is convenient to adjust the screen cloth elasticity, increases work efficiency, and solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the screen cloth elasticity adjusting device of high-frequency electromagnetic vibration sieve comprises the sieve nest of ratchet, ratchet, vibration sieve and the screen cloth axle of vibration sieve, ratchet is fixed on the screen cloth axle of vibration sieve, ratchet is fixed on the sieve nest of vibration sieve by hinge, the ratchet outer is provided with plurality of teeth, and ratchet mates with it mutually.
The screen cloth of vibration sieve hangs on the screen cloth axle, is provided with rotor at the end of screen cloth axle, the shaft core position of ratchet, and external force is applied on the rotor, can rotary screen axle and ratchet, and then can adjust the elasticity of screen cloth.Said rotor can be outer tetragonal body, or outer tripartite body, five side's bodies, hexahedron etc., clamp rotor with spanner, can come rotary screen axle and ratchet with manpower, also can wait the rotary screen axle, and then adjust the elasticity of screen cloth with electronic or hydraulic way.
Adopt the utility model, adjust the screen cloth elasticity of vibration sieve, be not afraid of corrosion with the click structure, if rise by into screen cloth, rotating ratchet, the tooth on the ratchet coupling ratchet, the ratchet tooth that whenever advances with regard to some screen clothes of tensioner, suits the requirements until the elasticity of screen cloth; Change screen cloth as needs, the ratchet backward rotation, ratchet withdraws from the coupling ratchet, and screen cloth is loosened.
The utlity model has rational in infrastructure, be not afraid of corrosion, be convenient to adjust the screen cloth elasticity, characteristics such as increase work efficiency, easy and simple to handle, not influenced by ore pulp moisture content and dust, be applicable to various vibration sieves.
Description of drawings:
Accompanying drawing 1 is the use location structural representation of the utility model embodiment.
Accompanying drawing 2 is structural representations of the utility model embodiment.
Among the figure: ratchet 1, ratchet 2, screen cloth axle 3, sieve nest 4, rotor 5, hinge 6.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The screen cloth elasticity adjusting device of high-frequency electromagnetic vibration sieve comprises ratchet 1, ratchet 2, screen cloth axle 3 and sieve nest 4, and ratchet 1 is fixed on the screen cloth axle 3, and ratchet 2 is fixed on the sieve nest 4 by hinge 6, and the ratchet outer is provided with plurality of teeth, and ratchet mates with it mutually.Screen cloth hangs on the screen cloth axle, is provided with rotor 5 at the end of screen cloth axle 3, the shaft core position of ratchet 1, and rotor is outer tetragonal body, with the outer four directions of spanner clamping rotor, can come rotary screen axle and ratchet with manpower, and then adjusts the elasticity of screen cloth.Change screen cloth as needs, the ratchet backward rotation, ratchet withdraws from the coupling ratchet, and screen cloth is loosened.
