Description

A kind of involute cut-in type pan feeding hydrocyclone

Technical field:

The utility model relates to mine fluid machinery, relates in particular to a kind of involute cut-in type pan feeding hydrocyclone.The utility model is applicable to the hydrocyclone of various diameter, can be used for ore pulp classification, desliming, the operation such as concentrated.

Background technology:

Conventional hydrocyclone charging aperture is generally engage with the form tangent with cylinder, after material enters hydrocyclone with high flow velocities, the tangential direction along cylindrical wall enters, and starts to rotate, such form often also exists larger pressure and flow velocity loss, and energy loss is large.

At present, because high abrasion natural rubber effectively can utilize the elastic deformation of self, absorb kinetic energy and the impact of solid particle, than antifriction metal (AFM) more erosion resistance; Rubber density is little, and pts wt is light, and installation is changed easy, is widely adopted in the operations such as ore dressing classification.When hydrocyclone runs, flow rate of pulp is high, and rubber liner vibrations are large, and rubber wearing and tearing are large, shorten its service life.

Summary of the invention:

In order to reduce the energy consumption of ore dressing, improve technical indicator and the economic benefit of ore dressing, the utility model proposes a kind of involute cut-in type pan feeding hydrocyclone, turbulence level can be down to minimum by this kind of feed-type, maximum is centrifugal force by kinetic transformation, thus reduction energy consumption, make cyclone can obtain larger disposal ability under lower feed force, improve technical indicator and the classification efficiency of ore dressing.

The utility model solves the technical scheme that its technical problem adopts:

A kind of involute cut-in type pan feeding hydrocyclone belongs to separation classifying equipoment, is made up of overflow short circuit, spin chamber's end cap, spin chamber's end cap shell, spin chamber's main body, spin chamber's main body cover, overflow pipe, epicone, epicone outrigger, mounting bracket, middle cone, middle cone shell, lower cone, lower cone shell, sand settling mouth, sand settling mouth shell, sand settling mouth sheath, securing member.

Described involute cut-in type pan feeding hydrocyclone is double-shell structure, comprise metal shell and wear-resistant liner, metal shell is used for supporting wear-resistant liner, and wear-resistant liner is used for wearing and tearing, as long as change wear-resistant liner after wear out failure, metal shell can Long-Time Service.

Described metal shell is different according to contour structures, bearing load, selects Q235 or cast iron to make; Wear-resistant liner material is different according to parameters such as each several part inner fluid mineralogical composition, concentration, and select the high-abrasive material that abrasive rubber, polyurethane or carborundum etc. are different, rubber liner mold pressing under high temperature, condition of high voltage forms.

Described spin chamber's split design, spin chamber's end cap 2 and spin chamber's main body 4 are sealed by V-type groove and dock, and effectively ensure product hermeticity.

The track of described spin chamber's feeding mouth passage 20 is a kind of involute, feeding mouth passage 20 cross section is smoothly transitted into rectangle gradually by square, ore pulp flows into spin chamber along this kind of involute path, meet the fluid characteristics of motion, at utmost reduce energy loss, make cyclone obtain maximum disposal ability under certain feed force.

Described spin chamber's cut water 19 place does local and thickeies design, and thickness progressively increases, and thickness reaches 8 ~ 10 times of all the other position wall thickness of spin chamber; Feeding mouth fillet 18 place does to strengthen fillet design, and feeding mouth fillet 18 is designed to 2 ~ 3 times of other three places fillets, increases allowance for abrasion, extends product service life.

The beneficial effects of the utility model are: the energy consumption reducing ore dressing, extend the service life of liner, improve technical indicator and the classification efficiency of ore dressing.

Detailed description of the invention

Realizing for making this novel practical reducing ore dressing energy consumption, increasing the effects such as the service life of liner, below in conjunction with concrete diagram, setting forth the utility model further.

As shown in Figure 1, mounting bracket 9 welds with epicone outrigger 8, spin chamber's end cap 2 is inserted in spin chamber's end cap shell 3, spin chamber's main body 4 is inserted in spin chamber's main body cover 5, and epicone 7 is inserted in epicone outrigger 8, and middle cone 10 is inserted in middle cone shell 11, lower cone 12 is inserted in lower cone shell 13, sand settling mouth 14 is inserted in sand settling mouth shell 15, and sand settling mouth sheath, overflow short circuit liner rubber, be connected and fixed above-mentioned part by securing member 17.

As shown in Figure 2, do at feeding mouth fillet 18 place easy to wear to strengthen fillet design, feeding mouth fillet 18 is designed to 2 ~ 3 times of other three places fillets, increases the allowance for abrasion at feeding mouth fillet place, extends product service life.

As shown in Figure 3, feeding mouth passage 20 track is a kind of involute, and feeding mouth passage 20 cross section is smoothly transitted into rectangle gradually by square, and material enters spin chamber along this involute, meets the fluid characteristics of motion, at utmost reduces energy loss.Spin chamber's cut water 19 place easy to wear does local and thickeies design, and thickness progressively increases, and thickness reaches 8 ~ 10 times of all the other position wall thickness of spin chamber, increases the allowance for abrasion at cut water 19 place of spin chamber, extends product service life.
