Description
Technical field
A kind of metallic particles screening plant relates to a kind of metallic particles screening plant that uses in inflammable, the explosive hazardous environment that is applicable to.
Technical background
In the process of the metallurgical preparation of carbonylation metallic particles, usually need to sieve out exactly to the metallic particles of prescribed level growing up.Because carbonylation metallurgical technology process is carried out under inflammable, explosive, hypertoxic environment, performance requirement to the metallic screen subset is very high, needs strict sealing usually, especially must guarantee the sealing of movable sealing system, and equipment will be easy to dismounting, guarantees that maintenance is convenient.Existing equipment is difficult to meet the demands.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, and a kind of metallic particles screening plant that can effectively sieve metallic particles in hypertoxic, inflammable, explosive hazardous environment is provided.
In order to realize above-mentioned purpose, the present invention by the following technical solutions.
A kind of metallic particles screening plant is characterized in that this device comprises array structure down:
Housing-this housing is the cylindrical cavity structure of an axial level, and the vertical plane of an end seals with steel plate, has a charging aperture; Other end vertical plane is with flange is fixedly connected, the axle center has labyrinth sealing chamber transmission axis hole vertical side shrouding;
Power transmission shaft-this power transmission shaft passes housing vertical side shrouding transmission axis hole and labyrinth sealing chamber, and an end stretches in the housing inner chamber, is fixed with a radial strip type bracing frame in its end; The other end connects with power set;
Basket-this filter sub-sieve basket is the truncated cone shape of open at both ends formula to the filter sub-sieve, is fixed on the axle by the radial strip type bracing frame on the power transmission shaft;
Feed pipe-this Guan Weiyi end has adpting flange, tilts to pass to be positioned at housing vertical plane sealing steel plate, and the pipe discharging opening is a low side, and is positioned at filter sub-sieve basket;
Undersize material discharge nozzle-this Guan Weiyi reducing pipe, the housing lower end that is positioned at suitable for reading, width is suitable with filter sub-sieve basket; The metal dust gathering-device links the lower end necking with sieving down by flange;
Oversize material discharge nozzle-this manages vertical riser, and a side pipe wall of pipeline upper end is positioned at the filter sub-sieve basket hole enlargement mouth inboard that keeps to the side; The lower channel mouth is gone up the metal dust gathering-device by flange and sieve and is linked.
A kind of metallic particles screening plant of the present utility model is characterized in that the material buffer deflection plate that the upper edge vertical fixing of feed pipe discharging opening has and hangs.

Adopt the metallic particles screening plant of utility model, can be implemented in severe toxicity, inflammable, the explosive hazardous environment metallic particles is sieved by size.Can in being divided into the hazardous environment of 2 districts (GB50058-92), explosive gas atmosphere and hazardous area work.Can realize that zero reveals, but the equipment long-time running.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of metallic particles screening plant, it is characterized in that this device comprises array structure down: this housing of housing 1-is the cylindrical cavity structure of an axial level, the vertical plane of an end has a charging aperture 3 with steel plate 2 sealings; Other end vertical plane is with flange is fixedly connected, the axle center has labyrinth sealing chamber transmission axis hole vertical side shrouding 4; This power transmission shaft of power transmission shaft 5-passes housing vertical side shrouding transmission axis hole and labyrinth sealing chamber 6, one ends stretch in the housing inner chamber, is fixed with a radial strip type bracing frame 7 in its end; The other end connects with power set 8; Filter sub-sieve basket 9-should filter the truncated cone shape that the sub-sieve basket is the open at both ends formula, was fixed on the axle by the radial strip type bracing frame on the power transmission shaft; This Guan Weiyi end of feed pipe 10-has adpting flange, tilts to pass to be positioned at housing vertical plane sealing steel plate, and the pipe discharging opening is a low side, and is positioned at filter sub-sieve basket; This Guan Weiyi reducing pipe of undersize material discharge nozzle 11-, the housing lower end that is positioned at suitable for reading, width is suitable with filter sub-sieve basket; The metal dust gathering-device links the lower end necking with sieving down by flange; Oversize material discharge nozzle 12-should manage vertical riser, and a side pipe wall of pipeline upper end is positioned at the filter sub-sieve basket hole enlargement mouth inboard that keeps to the side; The lower channel mouth is gone up the metal dust gathering-device by flange and sieve and is linked.Be the material buffer deflection plate 13 that the upper edge vertical fixing of feed pipe discharging opening has and hangs.Have in its turning cylinder and labyrinth sealing chamber and to be connected with cooling fluid cooling jacket 14.
15 is cooling water inlet in the accompanying drawing, and 16 is coolant outlet, and 17 is frame.18 is headstock.
During operation, the metal dust material is cushioned the deflection plate effect from feed pipe, and vertical landing is to filtering on the sub-sieve basket compass screen surface, and power transmission shaft drives the sieve basket, and fine grained passes compass screen surface and falls into the undersize material discharge nozzle; Coarse granule goes out sieve basket edge along skid under the compass screen surface, falls into oversize material discharge nozzle, finishes screening process, has realized the screening of metallic particles.End cap and housing adopt bolt to be connected, when cylinder breaks down, pull down end cap after, just can keep in repair after the cylinder taking-up.
