Filter aid add and precoat system.
In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of filter aid for filter press
Add and precoat system, it is characterised in that：Include pulvis chemicals feeder, pre- application preparation tank, mixing channel and automatic control system,
Mixing channel is equipped with pulvis feed inlet and wastewater sludge feed inlet, and pre- application preparation tank is equipped with pulvis feed inlet, and mixing channel passes through useless
Sewage sludge feed inlet is docked with wastewater sludge feeding machanism, while mixing channel and pre- application preparation tank pass through respective pulvis respectively
Feed inlet is docked with the pulvis discharge nozzle of pulvis chemicals feeder；The discharge port of pre- application preparation tank and mixing channel is connected to by conduit
Together, and by feeding of filter press system with feed opening of press filter it docks；Pulvis chemicals feeder is equipped with vibrating motor, and pulvis adds
Two sub-feed tubes of the pulvis discharge nozzle of medicine machine are respectively equipped with an electric gate valve, the pre- application preparation tank of vibrating motor, electric gate valve
And mixing channel connect to form respective automatic control structure with automatic control system respectively.Pulvis chemicals feeder is as filter aid pulvis
The directly composite device of addition and the charging of filter aid slurry, the flow direction of pulvis is can control by electrically operated valve, and passes through vibration
The frequency of motor can adjust the speed of pulvis discharging, filter aid made not add in real time online.
Further, the discharge port of pre- application preparation tank and mixing channel is respectively provided with control valve, and the control valve difference of the two
It connect the automatic control structure to form the process that discharges to pre- application preparation tank and mixing channel with automatic control system, makes pre- coating
Thickness and manufacturing speed can be controlled.
Further, the feeding of filter press system includes feed pump, and feed pump is equipped with frequency converter, frequency converter with from
Autocontrol system connects the automatic control structure to be formed to feed pump, and the delivery outlet of feed pump is docked with feed opening of press filter.
Further, the pre- application preparation tank and mixing channel are separately installed with blender.
Further, the feed pump is located at behind mixing channel, and mixing channel be located at precoat preparation tank and feed pump it
Between, pre- application preparation tank and mixing channel are connected to after same conduit and are connected to feed pump together by the conduit.
Preferably, the feed pump is screw pump, diaphragm pump, peristaltic pump, plunger pump or slurry centrifugal pump etc..
The utility model combines the foundation of pre- coating and two functions that add of filter aid, overcomes and helped in the past
The problem of filtering agent can not add in real time online, the thickness and manufacturing speed of pre- coating can also be controlled by automatic control system
System, so has promotion, while facilitating discharging and reducing filter press and slagging tap to the service life of canvas press cloth, the rate of filtration
Moisture content, realize the purpose of sludge reduction.
