Description

A kind of vertical type blotter press

Technology neck city

The utility model relates to a kind of filter press, in more detail, relates to a kind of vertical type blotter press.

Background technology

Filter press is a kind of widely used solid-liquid separating equipment.

Existing filtration pressure filter device is because structure technology adopts horizontal manual or semi-automatic pressure filtration more, and horizontal manual filtration sheet frame adopts plastic products, and production efficiency is low, environmental pollution is bigger; Semi-automatic vertical pressure filter is because equipment also adopts electric-control method, but because the automation matching property of other mechanism is relatively poor, its stability and production efficiency are lower, particularly when the seal chamber pressure-bearing, vibrations and hydrojet phenomenon appear in equipment, and in the cleaning of filter cloth, can not realize automation substantially, can't realize full-automatic press filtration processing truly.

Summary of the invention

The purpose of this utility model provides a kind of vertical type blotter press, it is simple in structure, filter efficiency is high, energy consumption is low, automaticity is high, product quality is high, easy to operate, safeguard simple, operating cost is low, pollution-free.

For achieving the above object, the vertical type blotter press that provides of the utility model mainly is included as:

Horizontal sheet frame group, for the stack of multilayer sheet frame horizontal direction forms, each laminate frame is to stack filter cloth and filter membrane on filter plate successively, forms mill room and filter chamber;

Each laminate frame side connects the squeezing pipe of a feed pipe and a high pressure gas or water;

Horizontal sheet frame group is installed in the centre of four hydraulic cylinders, and the piston rod of these four hydraulic cylinders is all fixedlyed connected with gland above the sheet frame of the horizontal sheet frame group the superiors;

The both sides of horizontal sheet frame group are provided with deflector roll and hydraulic motor or variable frequency reducer motor, and this hydraulic motor or variable frequency reducer motor drive and drive rod, make iterative motion at the annular filter cloth of driving under the effect of pressure roller on each deflector roll;

The filter cloth wash mill is made up of water pipe and high pressure water washing mouth, and this high pressure water washing mouth is located at the filter cloth both sides;

The feed pipe that above-mentioned hydraulic cylinder, filter cloth wash mill, hydraulic motor and each laminate frame connect all is connected a controller with high pressure gas squeezing pipe.

Wherein, the barrier film in the horizontal sheet frame group is embedded in and forms mill room on the filter plate.

Wherein, the filter cloth in the horizontal sheet frame group is provided with between barrier film and the filter plate and forms the filter chamber.

Wherein, hydraulic cylinder is connected on the base.

Wherein, controller is made up of central control unit, man-machine interface, probe unit, performance element, according to main setting program each signal is carried out computing, processing, or drives the magnetic valve action of performance element, or makes motor rotation, or sends the sound and light alarm signal.

The beneficial effects of the utility model are:

1) full automatic working;

2) blowing, washing leaching cake excellent in efficiency, the diaphragm pressing filter cake moisture is low, cleans filter cloth simultaneously;

3) floor space of filter press is little, and output is but very big;

4) filter plate has the squeezing film of rubber or the manufacturing of polypropylene material, and operation and maintenance cost are low.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

See also Fig. 1 and Fig. 2.Vertical type blotter press of the present utility model, comprise horizontal sheet frame group 1, this horizontal sheet frame group 1 is to be formed by the stack of multilayer sheet frame horizontal direction, each laminate frame is based on filter plate, on filter plate, stack filter cloth and filter membrane (rubber or polypropylene screen) successively, form mill room and filter chamber (need illustrate that the installation method of sheet frame and filter cloth and filter membrane is a known technology, seldom describes at this).The filter cloth that is installed in the horizontal sheet frame group 1 is annular filter cloth, is looped around between each metafiltration plate.

Horizontal sheet frame group 1 is installed in the centre of four hydraulic cylinders 2, and the piston rod 3 of these four hydraulic cylinders 2 is all fixedlyed connected fixing with the gland 1a of horizontal sheet frame group 1 the superiors.Be equipped with feed pipe 5 and high pressure gas squeezing pipe 6 in the side of each filter plate.

See also shown in Figure 3.The both sides of horizontal sheet frame group 1 are provided with deflector roll 7 and hydraulic motor (not shown), and this hydraulic motor drives the annular filter cloth 1b of driving rod 8 drivings and make iterative motion on deflector roll 7.On the correct position that filter cloth 1b rotates, filter cloth wash mill (as shown in Figure 4) is installed, the high pressure water washing mouth 10 in this filter cloth wash mill is located at the both sides of filter cloth 1b, and the water supply of this high pressure water washing mouth 10 is connected inlet opening 9 by a water pipe.

During practical operation, after feed liquid enters filter plate from the feed pipe 5 of each metafiltration plate, the sheet frame 1a that is driven the superiors by the piston rod 2a of hydraulic cylinder 2 makes top-down compressed action, filtrate in the feed liquid is extruded, for guaranteeing each compression effects, manage 6 to each metafiltration plate input high pressure gas, the filtrate in the compression filter cloth by the high pressure gas squeezing again.

After finishing once filtration, the piston rod 2a of hydraulic cylinder 2 is action upwards, makes between each metafiltration plate and throws off, and drives the annular filter cloth 1b of driving rod 8 drivings by hydraulic motor and make iterative motion on deflector roll 7.When filter cloth 1b rotated, filter residue came off from filter cloth, and by the both sides of high pressure water washing mouth 10 flushing filter clothes, cleaned filter cloth further.Be provided with because filter cloth be an annular, move and repeat aforesaid charging again after a week, squeeze supervisor.

Course of action of the present utility model is controlled by a controller fully.
