Abstract

The utility model discloses a novel filter pressing system of a belt filter press. The system comprises a lower filter belt and a dewatering roll, wherein an upper filter belt of a traditional belt filter press is omitted, so that the problems that during squeezing stage of mud after being subjected to dewatering under the action of gravity, plenty of mud flows back to a concentration tank along with the water squeezed out and repeatedly enters the belt filter press are solved. According to the utility model, when the mud passes through a lengthened gravity section, the water is separated under the action of gravity, the mud is squeezed and dewatered by utilizing a squeezing roll with a support ring and filter cakes up to the production standards in the aspect of the water content are obtained. The improved belt filter press has the advantages that the mud processing capacity is obviously increased; the production cost is reduced; and the labour intensity of workers is effectively reduced at the same time.

Description

A kind of belt filter press Novel pressure filter system

Technical field

The utility model relates to belt filter press transition band technical field, is specially a kind of belt filter press Novel pressure filter system.

Background technology

as shown in Figure 1, the transition band of existing belt filter press is comprised of lower transition band 2 and upper transition band 3, during mud process gravity section 6, water is separated under action of gravity, then be clipped between transition band 2 and lower transition band 3, enter undaform extruded segment 7, extruding by dehydration roll 5, with moisture from out, the extruding of dehydration roll 5 makes a large amount of mud flow out with water, turn back to again concentration basin through sand pump, again enter belt filter press, increasing along with required sewage load, cause the processing power of pressure filter can not reach needed treatment capacity far away, thereby had a strong impact on the normal production of whole system, workman's working strength has also increased in addition, cost of human resources increases.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of high-level efficiency, the novel strainer of belt filter press that easy and simple to handle, dehydrating effect is desirable.

In order to address the above problem, the utility model provides a kind of belt filter press Novel pressure filter system, comprises lower transition band and dehydration roll, and described lower transition band has formed around some dehydration rolls the loop that comprises gravity section, extruded segment and loop sections.

Extrusion roll two ends and the centre of described extruded segment all are equipped with support ring.

The wall thickness of described support ring is 3mm～10mm, can select to be fit to according to the needs of producing the support ring of wall thickness.

Compared with prior art, the beneficial effects of the utility model are:

Belt filter press strainer described in the utility model, removed upper transition band, and simplified time transition band, mud has reached good dehydrating effect through the dehydration of gravity section, pass through again the extruding with the extrusion roll of support ring, the water ratio of mud has reached the requirement of production, repeatedly get back to concentration basin with the water that squeezes out when having avoided so a large amount of mud through a plurality of dehydration roll extruding, improved the working efficiency of belt filter press, alleviate workman's labour intensity, saved simultaneously transition band and dehydration roll.

Description of drawings

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:

Fig. 1 is existing belt filter press belt structure schematic diagram;

Fig. 2 is the utility model structural representation;

Fig. 3 is the extrusion roll structural representation that support ring is installed described in the utility model.

In figure: 1-pressure filter intake zone, transition band under 2-, the upper transition band of 3-, 4-pressure filter discharge zone, the 5-dehydration roll,

The 51-extrusion roll, 6-gravity section, 7-extruded segment, 8-loop sections, 9-support ring.

Embodiment

As shown in Figure 2 and Figure 3, a kind of belt filter press Novel pressure filter described in the utility model system, comprise lower transition band 2 and dehydration roll 5, described lower transition band 2 has formed around the dehydration roll 5 of some different diameters the loop that comprises gravity section 6, extruded segment 7 and loop sections 8.enter lower transition band 2 through the mud after chemical flocculation from pressure filter intake zone 1, mud is in gravity section 6 moving process, water in mud is separated under action of gravity, mud enters extruded segment 7, extrusion roll 51 two ends and the centre that are in extruded segment 7 all are equipped with support ring 9, the wall thickness of described support ring 9 is 3mm～10mm, preferred 6mm, make between lower transition band 2 and dehydration roll 51 and have certain space, during mud process squeezing roller 51 place, be subject to slight squeeze, reach good dehydrating effect, simultaneously avoided again a large amount of mud to flow out with water because of larger squeeze, obtain at last the filter cake that water ratio reaches production standard, discharge from pressure filter discharge zone 4.

The utility model is to have carried out technological improvement on the prior art basis, has removed the upper transition band of pressure filter, has simplified time transition band 2, has greatly improved the treatment of mud ability of pressure filter, has reduced production cost, has effectively alleviated workman's labour intensity simultaneously.

Other structure of the described a kind of belt filter press Novel pressure filter of the present embodiment system is referring to prior art.

The above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, therefore every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
