Plate and frame filter press is owing to have: simple in structure, fault is few, easy maintenance, long service life, cost are low, material adaptability is reached advantages such as the filter cake water capacity is lower by force, is widely used in food, medicament, biochemistry, metallurgy, coal, environmental protection or the like industry.The mode that compresses according to sheet frame can be divided into: manually spiral compresses, mechanical spiral compresses, hydraulic pressure compresses and operation automatically.Wherein the cost performance of hydraulic compressing device is higher and easy to operate, the horizontal plate and frame filter press of the many again employings of hydraulic compressing device.
For the bigger metallurgy industry of the quantity of slag, adopt horizontal plate and frame filter press to filter slurry, the number of operations of hold down gag is more, and the sealing system of hydraulic means need stand anti abrasive test.The at present sealing system such as the accompanying drawing 2 of hydraulic means: in returning piston, install one close, act on and return piston and hold out against slit between the piston rod; Hold out against piston three sealings are installed, wherein hold out against piston seal and act on the slit that holds out against between piston and the stretch oil cylinder shell, return piston seat a sealing is installed, act on the slit of returning between piston seat and the stretch oil cylinder shell.Though this sealing system is simple, cost is relatively cheap, exists anti-wear performance relatively poor, changes the shortcoming of the sealing length consuming time on the piston.
In the production practices of zinc hydrometallurgy, after the hold down gag of horizontal plate and frame filter press uses for 3～April, must change and return piston seal and hold out against piston seal.Owing to change and to return piston seal and need dismantle the pressurize nut, hold out against piston and return piston seat, pressurize nut and hold out against the part that piston belongs to difficult dismounting wherein, the length that expends time in causes the equipment service efficiency low, the serious smoothness of producing that hinders.
Summary of the invention
At wearing no resistance that hydraulic means in the existing plate and frame filter press exists, change the defective of sealing length consuming time, hydraulic means in a kind of novel plate and frame filter press is provided, its technical scheme is as follows:
The utility model at the deficiency of the sealing system of hydraulic means in the horizontal plate and frame filter press provide a kind of simply, solution efficiently.
A kind of plate compression machine hydraulic equipment, comprise and hold out against piston rod, return piston, be positioned at the piston seal of returning on the piston of returning, return oil cylinder, be positioned at and return the in-oil cylinder piston rod of returning, the pressurize nut, stretch oil cylinder, what be positioned at stretch oil cylinder holds out against the piston Outboard Sections, is positioned at the piston seal that holds out against that holds out against the piston Outboard Sections, it is characterized in that: the described piston that holds out against is divided into and holds out against the piston Outboard Sections and hold out against the piston inside part, two parts are connected to each other, and sealing more than two is installed in the junction; Hold out against the piston Outboard Sections sealing more than two is installed.
The described piston that holds out against is divided into and holds out against the piston Outboard Sections and hold out against the piston inside part and be connected with bolt.
The described interior connecting bolt of piston that holds out against holds out against connection sealing in the piston.
The described piston of returning is installed plural sealing, returns piston seat plural sealing is installed.
Described plate compression machine hydraulic equipment also comprises the stretch oil cylinder shell, and the pressurization interface is positioned at the piston seat of returning on the piston seat of returning and seals, and is positioned at hydraulic means afterbody pressure release interface.
This utility model produces beneficial effect: by increasing sealing, brought up to 12～15 month from 3～4 months the service life that makes sealing system in the hydraulic means, improves 3 times service life; By being divided into two parts holding out against piston, solve and change when returning piston seal, the dismounting part is many, and labour intensity is big, the problem that lay day is long, and new sealing system is with respect to former sealing system, and house of correction needs cost low, the cost performance height, easy and simple to handle, be convenient to promote.
