Description

Anti-blocking funnel of disc press filter

Technical Field

The utility model relates to an anti-blocking funnel, in particular to an anti-blocking funnel of a disc press filter.

Background

The disc press filter is widely applied to dehydration filtration technology of mine concentrate and tailings, has the advantages of high working pressure, high processing capacity and high automation degree, the filtration system has less pollution to the site environment in a closed pressure bin, but is influenced by the property of the filtered ore, when the water content of a filter cake is bigger, the filter cake is easy to accumulate on the wall of an ore discharging funnel, so that the ore discharging funnel is blocked, the continuous and stable operation of equipment is influenced, and the problems of high cleaning frequency and high cleaning difficulty exist.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide the anti-blocking funnel of the disc press filter, which can effectively solve the problem that filter cakes are accumulated on the wall of an ore discharging funnel, ensure smooth ore discharging, greatly reduce labor intensity of workers and stabilize equipment operation.

The technical scheme of the utility model is as follows:

the utility model provides a disc press filter prevents stifled funnel, includes the funnel body, the border is fixed with anti-blocking bush on the funnel body, anti-blocking bush bottom natural sagging is not with the funnel wall contact, and anti-blocking bush's bottom is the binding off structure, anti-blocking bush adopts multifilament filter cloth, be fixed with a plurality of bolt on the funnel wall of border on the funnel body, anti-blocking bush upper border is equipped with the trompil that corresponds with the bolt, anti-blocking bush is established on the bolt through the trompil cover and is set up the layering in the anti-blocking bush outside that the cover is established, the layering outside sets up the nut.

Compared with the prior art, the utility model has the following advantages:

1. the bottom of the anti-blocking lining is of a closing-in structure, so that a filter cake cannot be accumulated under the action of gravity of the material, the funnel is effectively prevented from being blocked, and additional kinetic energy is not needed.

2. Simple structure is convenient for realize, and preparation and loading and unloading change are convenient, low cost.

3. The size can be universally applied to disc filters of different types after being properly adjusted.

Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the drawings

As shown in fig. 1-2, a disc press filter anti-blocking funnel comprises a funnel body 1, wherein an anti-blocking lining 2 is fixed on the upper edge of the funnel body 1, the bottom of the anti-blocking lining 2 naturally sags and does not contact with a funnel wall, a certain gap is kept, the bottom of the anti-blocking lining 2 is of a closing-in structure, the anti-blocking lining 2 adopts multifilament filter cloth, a plurality of bolts 3 are fixed on the funnel wall on the upper edge of the funnel body 1, openings corresponding to the bolts 3 are formed in the upper edge of the anti-blocking lining 2, the anti-blocking lining 2 is sleeved on the bolts 3 through the openings, a pressing strip 4 is arranged on the outer side of the well sleeved anti-blocking lining, the pressing strip 4 is an aluminum sheet, a nut 5 is arranged on the outer side of the pressing strip 4, the nut 5 is screwed when the anti-blocking lining 2 is fixed, and the nut 5 is unscrewed after the anti-blocking lining 2 is replaced.

The upper edge of the funnel body 1 is of a rectangular structure, the length is 1060mm, the width is 400mm, the length of the whole funnel is 2000mm, and 2-3 bolts 3 are welded on the upper edge of the funnel wall at equal intervals during installation and are used for fixing the anti-blocking lining 2 and the pressing strip 4; the upper edge of the anti-blocking lining 2 is perforated according to the position of the bolt 3, a pressing strip 4 is pressed at the perforated position, the multifilament filter cloth is prevented from being drawn and damaged, the periphery of the anti-blocking lining is tightly sewn, a main stress point is adopted here, the upper side of the anti-blocking lining 2 is fixed on the bolt 3, the pressing strip 4 is covered, the lining is further fixed, and then the nut 5 is screwed.

After the anti-blocking bushing is fixed, a certain gap can appear between the middle lower part of the bushing and the funnel wall, the bushing is in an adduction state as a whole, a filter cake which is unloaded in the running process of the filter can fall onto the bushing, and the filter cake is suspended around the bushing and can slide onto a belt below along the bushing without the support of the funnel, so that even if a small amount of filter cake is adhered to the bushing, the filter cake can fall along with accumulation under the influence of gravity.

When the anti-blocking lining 2 needs to be replaced, the nut 5 is unscrewed, the pressing bar 4 is taken down, a new lining is replaced, and the replacement is very convenient.

The unloading moisture of disc filter press is big, and the ore viscosity is big, and hard area ore is serious, the utility model discloses soft bush can let the material not contact the funnel wall, and the material depends on the dead weight and can fall down, can not accumulate, and this funnel is better on GPJ-120 disc filter press result of use, and the funnel jam problem has been thoroughly solved.

Claims (1)

1. A disc press filter prevents stifled funnel, its characterized in that: including the funnel body, the border is fixed with anti-blocking bush on the funnel body, anti-blocking bush bottom natural sagging does not contact with the funnel wall, and anti-blocking bush's bottom is the binding off structure, anti-blocking bush adopts multifilament filter cloth, be fixed with a plurality of bolt on the funnel wall of border on the funnel body, anti-blocking bush upper border is equipped with the trompil that corresponds with the bolt, anti-blocking bush is established on the bolt and is set up the layering in the anti-blocking bush outside that the cover is established through the trompil cover, the layering outside sets up the nut.
