Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in fig. 1, a proximity switch 4 is installed below a filter plate 5 of the filter press, the proximity switch 4 adopts a magnetic induction proximity switch with smaller non-contact loss, electric induction metal is induction iron, a metal head 3 is installed at the tail end of a water receiving disc 1, the induction head of the proximity switch 4 faces downwards, after the water receiving disc 1 entirely enters the lower part of the water receiving disc 1, the metal head 3 at the tail end and the proximity switch 4 generate induction, the proximity switch 4 is connected with a controller 9, and signals are transmitted to the controller 9. The gravity sensor 8 and the pulley 6 are arranged at the bottom of the water pan 1, and the pulley 6 is a pulley 6 with a bearing, so that the water pan 1 can move conveniently; the gravity sensor 8 is used for detecting the quality of the neutralization residue filter-pressed water in the water receiving disc, the gravity sensor 8 is connected with the controller 9, and a quality signal of the water received in the disc is fed back to the controller 9. At the slag bucket discharge position, two sets of electric push rods 2 are arranged in the pulling-out direction of the water receiving disc 1, a horizontal electric push rod is used, the stroke is 1300mm, the front ends of the electric push rods 2 are connected with the tail ends of the water receiving disc 1 through penetrating pins respectively, the electric push rods 2 enable the water receiving disc 1 to automatically push and pull below the filter plate 5, the electric push rods 2 are connected with a plc controller, and the controller 9 is used for controlling the water receiving disc. In order to ensure the moving speed and the moving efficiency of the water receiving disc 1 and reduce the abrasion of the pulley 6, a guide rail 7 is paved in the moving range from the electric push rod 2 to the water receiving disc 1 below the filter plate 5, the guide rail 7 is matched with the pulley 6, and the pulley 6 drives the water receiving disc 1 to move on the guide rail 7.

The working process of the utility model comprises the following steps: after the device is started, the controller 9 starts the electric push rod 2, the electric push rod 2 pushes the water receiving disc 1 to the left side of the filter plate 5 of the filter press, the device does not act when the front end of the water receiving disc 1 enters the lower part of the water receiving disc 1, the electric push rod 2 is continuously pushed in, when the whole water receiving disc 1 enters the lower part of the filter plate 5, the metal head 3 at the tail end and the proximity switch 4 generate induction, the proximity switch 4 transmits signals to the controller 9, the controller 9 stops driving the electric push rod 2, and the water receiving disc 1 automatically stops after being in place. At this moment, the filter plate 5 of the filter press starts to press slag, filtered water continuously enters the receiving tray 1, at this moment, the gravity sensor 8 detects the quality change in the receiving tray 1 in real time, when the pressing slag is finished, the detection value of the gravity sensor 8 is in a stable state, signals are transmitted to the controller 9, the controller 9 restarts the electric push rod 2 to retract, at this moment, the receiving tray 1 moves out from the lower part of the filter plate 5 and is pulled back to the initial position of the slag hopper side, at this moment, the limiting push rod stops, slag discharging is started to the slag hopper, a delay program is set in the controller 9, the slag discharging work can be finished by ensuring delay, and after the delay is finished, the device restarts to automatically finish the pushing operation of the receiving tray 1.
