Description
Technical field
The utility model belongs to the filter plant technical field, relates to a kind of filter.
Background technology
Liquid-solid separation is one of requisite unit operations of industry such as current chemical industry, pharmacy, food, and filter has obtained very using widely as the requisite equipment of the liquid-solid separation of a kind of realization.The basic principle of filter is by filter medium container to be divided into upper and lower chamber, and filtrate adds in the epicoele, and entering cavity of resorption by filter medium under pressure becomes filtrate, and solid particle is trapped within the filter medium surface and forms filter residue.In filter process, the filter cake layer that accumulate on the filter medium surface is thickeied gradually, and liquid increases by the resistance of filter cake layer thereupon, and the rate of filtration reduces.When filter chamber is full of filter residue or the rate of filtration too hour, must stop to filter, remove filter residue, filtration is carried out smoothly.
Existing traditional filter generally all comprises base and the cartridge assembly that is arranged on the base, wherein cartridge assembly comprises filter cylinder and following filter cylinder, following filter cylinder be provided with filter medium up and down filter cylinder separate and form upper and lower chamber, filtrate is through after the filtration of filter medium, and the filter residue of formation is trapped on the filter medium.The following filter cylinder of traditional filter all is fixed on the base, and filter cylinder removably is connected down on the filter cylinder on it.Can there be following inconvenience in such filter in actual use, because following filter cylinder is fixed on the base, for the filter residue on the filter assemblies is taken out or removes, need to go up that filter cylinder is whole to be taken off, make quantities extremely consume greatly, the wasting manpower and material resources, and expend time in, had a strong impact on the raising of production efficiency.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of filter that can take out the filter residue that filters generation quickly and easily.
The purpose of this utility model can realize by following technical proposal: a kind of filter, comprise the base that has column, be positioned at column one side at base and be provided with filter cylinder and following filter cylinder, described filter cylinder down removably is connected the upward filtration tube bottom, be provided with in the described down filter cylinder and can will go up the filter medium that filter cylinder cavity and following filter cylinder cavity separate, it is characterized in that, described upward filter cylinder is connected on the column and can is that rotate in the center of circle with the column, described down filter cylinder is slidingly connected on the column by a slide construction, also be provided with on the column can drive under the power set that reciprocatingly slide along the axis direction of column of filter cylinder.
Filter medium be in the filter operation in order to tackle the various porous materials of the contained solid particle of fluid filtrate, the filter medium in this filter includes silk screen, filter cloth and filter plate etc.This filter is when taking out filter residue, filter cylinder moves down only to need to rely on power set to drive down, and then rotates and go up filter cylinder, vacates down the superjacent air space of filter cylinder, just can very easily whole filter medium be taken off, and the filter residue that is trapped on the filter medium also is removed along band.Obviously, this filter takes out the very laborsaving convenience of process of filter residue, uses manpower and material resources sparingly, and the operating time weak point has improved production efficiency to a great extent simultaneously.
In above-mentioned filter, described slide construction comprises a sliding sleeve that is slidingly located on the column, and described sliding sleeve is connected mutually with above-mentioned following filter cylinder, also is provided with to prevent from sliding on the column the circumferentially guider of rotation between sliding sleeve and column.Be connected mutually by steel plate between sliding sleeve and the following filter cylinder.
As another situation, described slide construction is included in the column sidewall upper edge column axis direction relative with following filter cylinder and offers a bar shaped chute, sliding in the bar shaped chute is provided with a slide plate that can slide along bar shaped chute length direction, and described filter cylinder down is connected on the slide plate.
In above-mentioned filter, described power set are a worm gear screw lift, also be installed with the kink nut by a nut supporting plate on the sidewall of described sliding sleeve, fixed cover is provided with a lift axle sleeve on the described column, level is fixed with a lift supporting plate on the sidewall of described lift axle sleeve, vertically offer an installing hole on the lift supporting plate, described worm gear screw lift is installed on the lift supporting plate and the screw mandrel of worm gear screw lift passes above-mentioned installing hole rear screw and is connected on the kink nut.Between lift axle sleeve and column, also be provided with a lubricating sleeve of being made by polytetrafluoroethylmaterial material.The lift axle sleeve can directly be weldingly fixed on the column, or directly passes through bolting.As preferably, in this filter below column is positioned at the elevator shaft cover fixed cover be provided with the filler ring that can prevent the downward landing of lift axle sleeve, this filler ring is by being bolted on the column.Compare with direct fixedly lift axle sleeve, limit moving down of lift axle sleeve by filler ring, the I﹠M of energy easy of rise arbor cover.The worm gear screw lift is prior art, can directly buy to obtain on market, as Shandong Dezhou Jinyu Machinery Co., Ltd., Shanghai summit drive apparatus Co., Ltd etc. production is arranged all.Worm gear screw lift in this filter has laborsaving, automaticity advantages of higher by motor-driven in lifting process.
As another situation, described power set comprise a motor, and described motor is fixed on the column, are fixed with a screw rod with the output shaft concentric on the output shaft of motor, and described screw spiral is connected on the kink nut.Just changeing counter-rotating by motor and driving screw rod clockwise or rotate counterclockwise, moving up and down thereby drive the kink nut, driving down then, filter cylinder moves up and down.
