Abstract
The utility model belongs to the field of vibrating screens, and relates to a self-cleaning screen bar of a piano key type screen. The self-cleaning screen bar of the piano key type screen comprises a screen bar rib made of metal, the screen bar rib is L-shaped, a sleeve capable of freely moving is sheathed a position where the outer surface of the screen bar rib is positioned in front of a corner, the sleeve is made of wear-resistant metal, and the back side of the corner of the screen bar rib is used as a stopper for preventing the sleeve from falling. The self-cleaning screen bar of the piano key type screen has the beneficial effects of being simple in structure and convenient to use, effectively preventing the vibrating screen from being plugged; a large number of self-cleaning screen bars capable of jumping vertically form the piano key type screen, due to vertical jumping of the screen bar ribs and the vertical and horizontal free movement of the sleeve on the screen bar ribs, the difficulties that damp materials can be clung to holes, clamp holes and plug a pipe in screening process can be effectively solved under the condition of not washing, and the screening efficiency can be improved. With the adoption of the self-cleaning screen bar, the service life of the screen can be greatly prolonged, the wear of the screen bar ribs can be prevented, and the sleeve can be replaced after being worn.
Description
Technical field
The utility model belongs to the vibratory sieve field, relates to a kind of self-cleaning grating of key type screen mesh.
Background technology
In the coal screening refining process, because the dampness of coal, the bonding bridging of moist material causes sticking hole, hole clipping problem easily at present, except washing, does not have good solution at present.Therefore, the screen cloth of wet screen subset all washes sieve mostly with water, because washing sieve must by a large amount of water flushings, cause the waste of great lot of water resources.Although prior art has had many breakthroughs at self-cleaning function, band impacts the self-cleaning device of form of tubes, stores easily moist material in the pipe owing to impact, and loses efficacy easily in the process of constantly using.
Have at present at the screen bar sleeve of grating muscle installation with Weight plate, the Weight plate of adjacent grating muscle connects spacing by drag-line, but this product structure is complicated, and the screen bar sleeve activity is limited, cause easily in screening process the clamping phenomenon of material, the self-cleaning effect is undesirable.And grating fixedly rubber and/or ceramic protection layer, wearing layer also cause easily in screening process the clamping phenomenon of material, also reduced the flow velocity of material, ectocrine material screen divisional processing efficient simultaneously.
Summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of simple in structure, easy to use, effectively prevent from the self-cleaning grating of the key type screen mesh of vibratory sieve hole clipping from can solving the easily problem of the sticking hole of deliquescence material, hole clipping such as screened coal, coke, rawore.
The utility model is achieved by the following technical solution:
The self-cleaning grating of key type screen mesh of the present utility model, its special character is: comprise metal grating muscle, the grating muscle is L-shaped, surface cover had the freely sleeve pipe of activity before grating muscle outside was positioned at the turning, sleeve pipe is made by antifriction metal (AFM), and the back, turning of grating muscle is as being used for preventing the stopper that sleeve pipe comes off.
The beneficial effects of the utility model are, simple in structure, easy to use, effectively prevent the vibratory sieve hole clipping, the key type screen mesh that self-cleaning grating that in a large number can bob forms, because the bob of grating muscle and the sleeve pipe up and down freely activity on the grating muscle, efficiently solve moist material and in screening process, be stained with the difficult problem of hole, hole clipping, plugging, in the situation of not washing, effectively solved this difficult problem, saved water resource, improved screening efficiency, screening efficiency has been reached more than 90%.This product can improve again the service life of screen cloth greatly, prevents the wearing and tearing of grating muscle, can change behind the casing wear.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 grating muscle, 2 sleeve pipes, 3 stoppers.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
The self-cleaning grating of key type screen mesh of the present utility model, comprise metal grating muscle 1, the grating muscle is L-shaped, and surface cover had the freely sleeve pipe 2 of activity before grating muscle outside was positioned at the turning, sleeve pipe is made by antifriction metal (AFM), and the back, turning of grating muscle is as being used for preventing the stopper 3 that sleeve pipe comes off.
The self-cleaning grating of key type screen mesh of the present utility model, operation principle is, vibration at high speed after vibratory sieve starts, material drives into into downward-sloping screen cloth by the even cloth of feedboard, material is fully screening under the vibration of screen cloth, bulk materials is along the screen cloth down sliding, and the discharging opening from the screen cloth end flows out at last, and fine crushing material is derived from the flue-dust retainer that screen cloth falls below screen cloth.The key type screen mesh that employing is formed by parallel L shaped grating that in a large number can bob, each button grating cantilever end is done irregular bob, the up and down freely activity of sleeve pipe on the grating muscle, make the sieve seam be in the dither state, attachment on tamper and the compass screen surface is shaken, effectively prevent the bonding bridging of material and grating, solve moist material and in screening process, be stained with the difficult problem of hole, plugging, also efficiently solve the problem of critical particle hole clipping, screening efficiency has been reached more than 90%.
