Abstract

The utility model relates to a solution filtering device, which belongs to a cylindrical continuous filter press. The utility model can improve the effective rate of the filtering area by using the bottom net, so the filter cloth can be protected in the meantime, without getting into the slot in the processes of working and being reduced the destroy from the pull force; the surface net is enhanced, so the filter cloth can be not worn by the spiral propeller during the working and the maintain the normal state in the processes of backwashing or backflushing filter cake, improving the service life of the filter cloth and reducing the changing times of the filter cloth; the variable pitch end and the cone end of the propeller can improve the quantity of the slag with solid.

Description

Continuous filter

The utility model relates to a kind of solution filtering device.Particularly a kind of drum type brake continuous filter, it belongs to filter.Gone in the tube by pumping liquid during work, filtrate flows into cannelure by filter cloth to the circumference radiation and leads to the discharging tube system, and slag is extruded toward the awl tail, and the one side of filter cloth contact filter cake has the enhancing net.

In the prior art, filter cloth cracky in the drum type brake filter often will change filter cloth, and also relatively more difficult when changing filter cloth, the deslagging solid content is also low.

The purpose of this utility model is to overcome the deficiency of above-mentioned existence and a kind of filter cloth that can be convenient to change is provided, and improves filter cloth service life, reduces and changes the filter cloth number of times, increases effective filtration area, improves the continuous filter of filter efficiency.

The purpose that the utility model proposed realizes with following technical scheme.

This continuous filter mainly is made up of aft mount, afterbody, cylindrical shell, fixed part and transmission, removes aft mount and afterbody when changing filter cloth and changes filter cloth with regard to extensible cylinder, has changed and has retracted the original place; It also is that machine is finished changing outward and just moved to the original place that afterbody changes filter cloth, and last bearing installs this machine resumes work again, so it is also convenient to change filter cloth.

Cylinder and afterbody cone liner plate all are that the RPP car circularizes groove; and be drilled with the discharge opeing duct; the sheet frame that is equivalent to filter press; just paste on the cannelure muscle top of obeying and assist macropore mesh nylon spacer screen at filter cloth; or stainless (steel) wire; it can increase the effective filtration area of filter cloth and protect filter cloth again; reduce the filter cloth tension under pressure and damage; the one side of filter cloth contact filter cake is aided with more the macropore mesh again and reinforced stainless (steel) wire has protected filter cloth not to be subjected to spiral propeller to scrape damage, and filter cloth is lived by support when backwash simultaneously or stripping filter cake.Improve its service life by this two nets protection filter cloth.

Spiral propeller makes tube interior filter cake in garden remain on work under the certain thickness, and filtering velocity is relatively stable.Spiral afterbody pitch reduces gradually, and tapered diminish and the afterbody taper matches, and filter cake is extruded under the squeezing state like this, can improve its solid content.

Description of drawings is as follows:

Fig. 1 is the utility model front view

Fig. 2 is the utility model A enlarged drawing

Fig. 3 is the utility model B enlarged drawing

Following the utility model will be further described in conjunction with the embodiments:

As shown in Figure 1, continuous filter mainly is made up of spiral propeller 1, end socket 2, worm gear 3, garden cylindrical shell 4, afterbody 5, bracket at tail part 6.

Garden cylindrical shell 4 is supported by two stands 7 and straining beam 8 pulls into one, drainage system 9 conveniently assemble and disassemble that also fuses with it.End socket 2 has liner plate 10 and inlet connector tube 11, and support 12 also has hold-down support 13 to be formed in when changing filter cloth the propeller cantilever, and this just is convenient to change filter cloth and maintenance operation.

As shown in Figure 2; garden cylindrical shell 4 is combined by the RPP of multi-disc; the ground floor net 14 of its inwall should be 8-40 order nylon wire, or stainless (steel) wire, and its protection filter cloth 15 is not absorbed in the groove under pressure; avoid pulling open; the specification of stainless (steel) wire 16 is in 8 orders, and it has vertical muscle 17 and horizontal bar 18 protection veils simultaneously, and purpose is still in order to make filter cloth be in the normal position; do not gall filter cloth, not take off the displacement of filter cake filter cloth yet because of backwash or blowback because of propeller rotates.

As shown in Figure 3, afterbody has liner plate 19, taper spacer screen 20, and specification is a 8-20 order nylon wire, filter cloth 21 is also for taper, veil 22, specification is in 8 orders, and vertical muscle 23 is arranged simultaneously, and horizontal bar 24 is strengthened veils, and this also is in order to protect filter cloth and to increase effective filtration area.25 is bushing pipe, and 26 is residue outlet.

Solution enters chamber within the cylinder 4 by being pumped into through inlet connector tube 11 during work, and filtrate flows into cannelure from filter cloth to the circumference radiation and leads to drainage system 9.Filter cake is shifted onto afterbody by spiral propeller and is pushed discharge again, and a filter cake keeps a certain thickness to make filtyration velocity relatively stable in the tube.

Claims

1, a kind of drum type brake continuous filter of solution filtration, gone in the tube by pumping solution during work, filtrate flows into cannelure by filter cloth to the circumference radiation and leads to the discharging tube system, and slag is extruded toward the awl tail, it is characterized in that: be equipped with spacer screen 14, its specification is 8-40 order nylon wire or stainless (steel) wire.

2, continuous filter as claimed in claim 1 is characterized in that: the one side of filter cloth contact filter cake has the veil 16 of enhancing.

3, continuous filter as claimed in claim 1 is characterized in that: spiral propeller 1 afterbody pitch is gradually little.

4, continuous filter as claimed in claim 1 is characterized in that: afterbody cone 5 is descending.
