Description

Drawing mechanism for unloading multiple filtering plates of press filter

The utility model relates to many filter plates discharging simultaneously plate pulling device on a kind of plate and frame type filter-press, is widely used in the relevant industry that coal separation, chemical industry, metallurgy etc. need be made Separation of Solid and Liquid.

The employed automatic discharge unit of filter press is and once draws a filter plate discharging, its inefficiency at present, trace it to its cause and be arm-tie shedding mechanism unreasonable structure, because be in operation at pulling car, because the obstruction of nigger, dolly can only once draw one.

It is a kind of improved that the purpose of this utility model is to provide, and can once draw many filter plates discharging simultaneously plate pulling device on the filter press more than two.

The purpose of this utility model is achieved like this, situation according to the work of present discharging arm-tie is seen, roughly be divided into and compress, pan feeding, the pine Keyboard, four operations of arm-tie discharging, after first three operation is finished, carry out the arm-tie discharging again, the arm-tie discharging is to move back and forth by spurring the arm-tie car by sprocket wheel drive chain, two shifting blocks are housed on the arm-tie car, preceding shifting block hauls by spring, stressed can falling to a spring, the reliable again spring force of mistake power erects automatically, back shifting block is by the control of the office in the pulling car, can when erecting, preceding shifting block fall down, preceding shifting block erects when falling down, when pulling car moves to right, preceding shifting block bumps first filter plate handle, overcome spring force, the instantaneous handle of crossing first filter plate of bending, back shifting block erects, blocked by first handle and to stop to move to right, hydraulic working oil pressure raises, pressure switch will be controlled the reversal valve commutation, the hydraulic motor counter-rotating, the drive plate of pulling a cart moves to left, preceding shifting block on the dolly is dialled handle through first filter plate and is moved to left (after preceding shifting block erects, back shifting block stoops again automatically), the interior filter cake of groove this moment then unloads automatically, wait to draw filter plate to the end during Board position, the arm-tie car is obstructed again, and operating pressure raises again, another pressure switch is controlled the reversal valve commutation again, then hydraulic motor rotates again and drives the arm-tie car and move to right, and removes to draw second filter plate, so goes round and begins again, dolly moves back and forth, until filter plate is pulled, discharging finishes, in this course of work, can be clearly seen that, as long as improve the handle on the filter plate, but make its dolly do not stopped just Duola's filter plate, for this reason by the handle on next piece, handle on the filter plate there is the long weak point that has instead, or, filter plate is linked as one group one group by attachment according to what of a pulling block of need, go up the dress nigger for first of every group, all the other are short handle, and short handle only need remove nigger top also can.

The utility model is simple in structure, is easy to original equipment is transformed, and cost is low, the efficient height, and popularizing value is big.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.
