Abstract

The utility model discloses a bimetal combined cyclone apparatus. Each component is composed of a casing and an inner lining, wherein, the casing is made from general steel plates, and the inner lining is cast by using wear-resistant materials. A mould of the inner lining is made from polystyrene foam plastics, and then the mould is arranged inside the casing. The inner wall of the mould is brushed with refractory paint. The inner lining and the casing are cast into a whole by adopting the combined method of vacuum casting of expendable mould. The utility model has the advantages of good wear-resistant performance, strong corrosion-resistant performance, favorable whole performance, simple manufacture technology, and low cost. The utility model can produce various bimetal combined cyclone apparatuses with different shapes and specifications. The utility model is suitable for the technical fields, such as dust collection, pneumatic conveying, material selecting, etc.

Description

The compound cyclone of bimetallic

The utility model relates to free swirl-flow devices of a kind of application or laminar product, the compound cyclone of particularly a kind of bimetallic.

Cyclone is to utilize centrifugal force to carry out the device of classification in rotary current.Early than appearing at Holland the end of the thirties, because simple in structure, disposal ability is big, technological effect is good, and now be widely used in classification, concentrated, in the operations such as dehydration, dedusting, but because the cyclone barrel that general steel plate is made is thinner, be easy to wearing and tearing, influenced service life.In order to solve wear problem, traditional method is to stud with glass-ceramic diabase liner plate or rubber lining at the cyclone inwall, improves service life.The weak point of the method is: (1) inside and outside two-layer mechanical bond that is, bond strength is low, because cast stone lining and cast stone is that a piece is built into, so globality is poor.In use, be subjected to percussion after, be easy to chipping or peel off, result in blockage, influence is produced; (2) this cyclone inwall is very coarse, and momentum consumption is big, and influences the quality and the efficient of classification and dedusting; (3) interior wall thickness, complex manufacturing technology is difficult to be adapted to the less cyclone of barrel dliameter, and production efficiency is low, cost is high; (4) anti-wear performance is poor, uses mission short.

This reality is made the compound cyclone of bimetallic that novel purpose is to provide a kind of difformity and specification.This cyclone bond strength height, anti-wear performance are good, long service life, production technology is simple, easy to make, product cost is low.

It is such that this reality is made novel technical solution: the compound cyclone of bimetallic, comprise feed pipe (1), overflow pipe (2), cylindrical shell (3), cone (4) and jetsam mouth parts such as (5), each parts all is made up of shell and liner two parts, shell adopts general steel plate to make, and liner is cast with high-abrasive material; Make the model of liner earlier with polystyrene foam plastics, again this model is packed in the shell, brush fireproof coating, adopt disappearance mould suction pouring complex method, liner and shell are cast for one at this model inwall.

This cyclone shell can adopt A ₃General steel plate is made, and liner can adopt high-abrasive material castings such as general white cast-iron, rich chromium cast iron or ni-hard cast iron.

The utility model compared with prior art has the following advantages:

(1) has good abrasion-proof corrosion-proof performance and mechanical property.Metallurgical binding area between the ectonexine reaches more than 80%, and bond strength height, strong, safe and reliable, the long service life of globality can not produce and peel off or cracked.

(2) but once-cast be shaped.Manufacture craft is simple, easy to operate, production efficiency is high, product cost is low, remarkable in economical benefits.

(3) this utility model is of many uses, can produce the compound cyclone of bimetallic of various different barrel dliameters, difformity and specification, to satisfy the production technology needs in different technologies field.The cyclone dust collectors that use in tripper in carrying as strength, the separator that the material branch is chosen and the environmental protection etc.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the compound cyclone embodiment 1 of bimetallic.

Fig. 2 is the profile of Fig. 1.

Fig. 3 is the structural representation of the compound cyclone embodiment 2 of bimetallic.

Fig. 4 is the profile of Fig. 3.

Embodiment 1:

See figures.1.and.2.A kind of compound hydrocyclone of bimetallic that can be used for the sorting specialty, its each parts all are made up of shell and liner two parts.These parts comprise feed pipe (1), overflow pipe (2), cylindrical shell (3), cone (4) and jetsam mouth (5) etc.Shell adopts general steel plate to make, and liner adopts high-abrasive material castings such as general white cast-iron or rich chromium cast iron or ni-hard cast iron.Concrete manufacture process is: the model of making liner earlier with polystyrene foam plastics, according to different technological requirements, determine the wall thickness dimension of model, the internal diameter size and the shape of the internal diameter size of this model and shape and shell are complementary, put into shell making good model then, brush one deck fireproof coating at this model inwall, whole cyclone model is imbedded in the molding sand, running gate system is installed, adopt disappearance mould suction pouring complex method, cast iron is cast on the model, liner and shell metallurgical junction are integrated, promptly make the compound cyclone of bimetallic.

Embodiment 2:

With reference to Fig. 2 and Fig. 4.A kind of compound cyclone dust collectors of bimetallic that can be used for the dedusting specialty, its each parts all are made up of shell and liner two parts, and these parts comprise air inlet pipe (1), blast pipe (2), cylindrical shell (3), cone (4) and ash hole (5) etc.Shell adopts general steel plate to make, and liner adopts high-abrasive material castings such as general white cast-iron, rich chromium cast iron or ni-hard cast iron.Manufacturing process is with embodiment 1.
