Abstract
The utility model discloses a dumbbell-type pressure roll for a belt filter press, which comprises a cylinder and a cone body. When the dumbbell-type pressure roll is arranged on the belt filter press, a gap is naturally formed between the paired pressure rolls arranged on the dumbbell-type pressure roll. The gap is in a rectangular shape, a circular table shape or other geometrical shapes. When passing through a paired roll extrusion area, materials can be extruded uniformly from the middle to both sides so as to reduce the integral water content of the filter cake effectively and improve the dehydrating efficiency of the belt filter press obviously.
Description
Technical field
The utility model belongs to the dehydration equipment field, particularly a kind of belt filter press dumb-bell shape pressure roll that improves the belt filter press solid-liquid separation efficiency.
Technical background
In the production practices of using belt filter press that the high-moisture material is dewatered, in order further to improve dewatering efficiency, often mounted in pairs pressure roll on belt filter press carries out the extruding of high pressure to material, and has obtained dehydrating effect preferably.Because the dehydrated material water content is higher, also has certain fluidity,, its entering pressor areas just can form the wedge shape filter cake that the middle part is thick, both sides are thin at last when being squeezed to two side shiftings of strainer.But the pressure roll that mounted in pairs is used on the existing belt filter press all is columniform; What form during two pressure roll mutual extrusion is one and is similar to linear pressure area; So have only the material at the middle thicker position of filter cake just can be squeezed and receive bigger extruding force, and the material at thin position, both sides does not reach roll surface, the very little even power that is not squeezed of the extruding force that receives basically; Cause the material of filter cake middle part after the press filtration and the material moisture of both sides to differ greatly; The water content of middle part is low, and the water content of both sides is high, has finally influenced the whole dewatering efficiency of belt filter press.So these above defectives become the technical barrier of the industry.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists on the existing belt filter press pressure roll design and fabrication, and a kind of belt filter press dumb-bell shape pressure roll that can further improve solid-liquid separation efficiency is provided.
The technical scheme of the utility model is achieved in that
This belt filter press novel pressure roller; Be characterized in: described dumb-bell shape pressure roll comprises cylinder and Rotary-table; When described dumb-bell shape pressure roll is installed on belt filter press; To pressure roll is housed, and to formation gap naturally between the pressure roll of dress, described gap is rectangle, truncated cone-shaped or other geometric figure.
Above-described dumb-bell shape pressure roll is installed one at least on every belt filter press.
The pressure roll of above-described cylinder and Rotary-table is face seal or cylindrical shell with holes.
Above-described cylinder and Rotary-table form through the processing metal drum surface or finished surface kiss-coating layer forms.
The utility model compared with prior art has following outstanding feature:
When becoming pair roller to install when dumb-bell shape pressure roll mounted in pairs or with the cylinder pressure roller; Just can form a tapered region on the contact wire of two rollers; This can just match with " the wedge shape filter cake that the middle part is thick, both sides the are thin " shape in the pressure area; Each position of filter cake can both contact and receive the extruding force of roller with roller surface, helps further improving the dewatering efficiency of belt filter press, when having solved the roll-to-roll extruding of existing belt filter press cylindrical pressure; Have only the material at the middle thicker position of filter cake just can be squeezed and receive bigger extruding force; And the material at thin position, both sides does not reach roll surface basically, and the very little even power that is not squeezed of the extruding force that receives causes the material of filter cake middle part after the press filtration and the material moisture of both sides to differ greatly; The water content of middle part is low, the technological deficiency that the water content of both sides is high.

The specific embodiment
The structure of the utility model is described below in conjunction with accompanying drawing and embodiment.
Shown in Fig. 1～3; The belt filter press dumb-bell shape pressure roll of the utility model, comprise cylindrical 1 with both sides truncated cone-shaped 2 in the opposite direction, the upper base of Rotary-table 2 is connected with the two ends of cylinder 1; The diameter of upper base equals the diameter of cylinder 1; Described dumb-bell shape pressure roll is to arrange in pairs, and this paired pressure roller is by form the gap between the mutual pair roller of cylinder naturally, and described dumb-bell shape pressure roll is to arrange in pairs; Described gap is rectangle such as cylindrical region 3; Or truncated cone-shaped such as truncated cone-shaped zone 4, or the combination of rectangle (cylindrical region 3) rectangle and truncated cone-shaped (truncated cone-shaped zone 4), formed wedge gap and rectangle gap help the pressurization of being squeezed material and keep the suitable squeezing time.
Operation principle: shown in Fig. 1～3; When belt filter press carries out press filtration work; When passing through, filter cake arranges in pairs that by a plain cylindrical form pressure roll and dumb-bell shape pressure roll perhaps two dumb-bell shape pressure rolls are arranged the pair roller press filtration district of formation in pairs, the middle small cylindrical zone 3 that is in dumb-bell shape pressure roll rectangle gap than the thickness portion material; The thin partial material in both sides is in two truncated cone-shaped zones 4 of dumb-bell shape pressure roll both sides wedge gap; No material strainer is in two great circle cylindricalitys zone, dumb-bell shape pressure roll two ends 3, in the filter cake each position all contact and receive evenly with roll surface, enough big pressure, effectively avoided filter cake mid portion water content low; The appearance of the high phenomenon of two side portions water content, thus reach the purpose of further raising belt filter press dewatering efficiency.
Referring to as shown in Figure 1, pressure roll adopts the structure of dumb-bell shape to be: two ends are that two Rotary-tables 2, middle part are cylinder 1.As the pressure roll of two dumb-bell shapes when rolling work (referring to Fig. 2 and shown in Figure 3); The both sides of roller have constituted the truncated cone-shaped zone 4 that certain interval is arranged; The middle part has constituted has the great circle of certain interval cylindricality zone 3, and the upper base diameter of both sides Rotary-table 2 equals the diameter of mediate cylindrical 1.
Referring to as shown in Figure 4, pressure roll adopts the structure of dumb-bell shape to be: the middle part is that a small cylinder 1, two ends are two large cylinders 1, is Rotary-table 2 between small cylinder 1 and the large cylinder 1.When the pressure roll mounted in pairs of two dumb-bell shapes (referring to Fig. 5 and shown in Figure 6); The both sides of roller have constituted two great circle cylindricality zones of being close to 3; The middle part has constituted the small cylindrical zone 3 that certain interval is arranged; Then constituted the truncated cone-shaped zone 4 that certain interval is arranged between two Rotary-tables 2, the upper base diameter of both sides Rotary-table 2 equals the diameter of middle part small cylinder 1, and the diameter of going to the bottom of both sides Rotary-table 2 equals the diameter of two ends large cylinder 1 cylindrical region.
