Abstract
A hydraulic double-screw locking and pressure-maintaining device for a filter press adopts the structure screw holes are formed in the two sides of an oil cylinder mounted on a base of the filter press; shaft sleeves are mounted in the screw holes, welded with shaft sleeve flanges and connected with the base; the shaft sleeve flanges are connected with locking nuts; double screws are mounted in the shaft sleeves in the screw holes in the base; a compressing plate is welded with compressing plate flanges; grooves are formed in the double screws; square heads or flat heads are arranged on the double screws; square holes or flat holes of the compressing plate flanges are connected with the square heads or the flat heads of the double screws; a clamping plate is connected with the grooves in the double screws, and mounted on the pressing plate flanges; cylindrical plate handles are arranged on the locking nuts; when the double screws are locked and fixed, the locked pressure can compress a filter plate to enable the pressure to be balanced, the sealing performance of the filter plate is good, and hydraulic pressure supplementation is not required, so that the energy is saved; when the double screws are locked, pressure maintaining is realized, the filter plate is compressed to enable the filter plate to be resistant to high pressure impact. Through the adoption of the device, the service lives of the oil cylinder body and hydraulic pieces are prolonged, and the press filter is safe to use on a filtering site.
Description
Technical field
The present invention is filter plant filter press field, furthermore, relates to a kind of filter press Hydraulic Double screw rod locking pressurizer.
Background technology
Filter press is the main filtration equipment in Separation of Solid and Liquid industry, compress filter plate sealing filter chamber by hydraulic system during material filtering and form filter element, by the pressure of feed pump, material is injected each filter chamber, hydraulic compression pressure keeps being greater than feed pressure filter chamber just can not leak material, hydraulic compression automatic pressure-maintaining ftercompction sealing filter chamber completes feed pump fed filtration, realizes Separation of Solid and Liquid object.
Filter press finds that there is weak point in the charging of use hydraulic compression automatic pressure-maintaining, because filter press adapts to various material filtering, during filtration material feeding pressure and feed time different, especially the material filtering that chemical industry has uses high pressure charging, some material filtering feed time can reach tens hours, automatic pressure-maintaining causes the frequent ftercompction of hydraulic pressure, hydraulic part is made to reduce service life, the power supply of loss simultaneously increases production cost, high pressure charging occasional produces impulsive force, filter chamber pressure is raised fast, cylinder pressure is caused to rise instantaneously, it is dangerous that charging impulsive force makes hydraulic part damage cylinder body appearance, cause Filter Press scene dangerous, thus production is affected.
Summary of the invention
The present invention seeks to solve the weak point existed in above-mentioned background technology, and provide a kind of filter press Hydraulic Double screw rod to lock pressurizer.
To achieve these goals, the invention provides a kind of filter press Hydraulic Double screw rod locking pressurizer, the cylinder body both sides of installing at filter press support arrange screw hole, in screw hole, axle sleeve is installed, this axle sleeve welding axle sleeve ring flange connects support, axle sleeve ring flange connects locking nut, arranging twin-screw is arranged in support screw hole axle sleeve, pressure strip welding pressure strip flange, pressure strip flange endoporus is square opening or flat hole, twin-screw arranges groove, twin-screw also arranges square spigot or flat head, pressure strip flange square opening or flat hole connect twin-screw square spigot or flat head, be provided with clamp and connect twin-screw groove, clamp is arranged on above pressure strip flange, twin-screw arranges trapezoidal thread configuration lock jack panel, cylindrical plate is set being arranged on locking nut.
Described axle sleeve ring flange connects locking nut, and axle sleeve ring flange is provided with boss and connects locking nut.
Pressurize fed filtration stability and safety effect is locked by enforcement filter press hydraulic compression filter plate twin-screw of the present invention, it is large that twin-screw arranges trapezoidal thread configuration lock jack panel compression filter plate intensity, twin-screw arranges square spigot or flat head coordinates pressure strip flange square opening or flat hole, locking nut rotational lock twin-screw can not rotate, the twin-screw Prssure lock that is locked presses tight filter plate pressure balance, filter plate good seal performance, Filter Press hydraulic pressure no longer ftercompction saves the energy, twin-screw locking pressurize compresses the high pressure resistant impulsive force of filter plate, this device makes cylinder body and hydraulic part increase the service life, Filter Press onsite application safety, the simple installation and maintenance of this structure are easy to use, improve filter efficiency.
