The screening and inflating device comprises a machine frame, a grating screen, a plastic bag, a charging basket and a gas bottle. The grating screen is located on the upper portion of the machine frame, the charging basket is located on the lower portion of the machine frame and located under the grating screen, the grating screen is connected with a motor through a speed reducer, screen cloth is arranged in the grating screen, and the lower end of the screen cloth is connected with an inverted-cone-shaped hopper. The plastic bag is arranged in the charging basket, and an opening of the plastic bag is in seal connection with an outlet of the hopper. The gas bottle is connected with a gas outlet pipe through a pressure reducing valve, a gas outlet of the gas outlet pipe is connected with the outlet of the hopper and stretches into the plastic bag, the gas bottle is filled with inert gas, and the inert gas is argon or nitrogen.
Description
Technical field
The utility model relates to a kind of industrial goods, especially a kind of sieve material aerating device for carbide alloy process.
Background technology
The first operation of CEMENTED CARBIDE PRODUCTION is to prepare compound, because the granularity of compound is very thin, as: cobalt powder granularity is generally 1.0 ~ 1.5um, and WC particle is generally 0.6 ~ 2.5 um, CK32 particle is generally 1.0 ~ 2.5 um, and (TaNb) C solid solution particle is generally 1.0 ~ 2.0um.After mixed slurry is dried, need to be through the discharging technique of sieving, existing screen method is directly in air, to sieve, and when compound contacts with air, can be oxidized, and is unfavorable for stablizing of product quality.
Utility model content
The utility model is intended to address the above problem, and a kind of sieve material aerating device is provided, the oxidation of air to compound when this device can reduce compound and sieves, and its technical scheme adopting is as follows:
A kind of sieve material aerating device, comprise frame, wipe broken sieve, polybag, charging basket and gas cylinder, the broken sieve of described wiping is positioned at upper rack, described charging basket is positioned at frame lower, and be positioned at wipe broken sieve under, the broken sieve of described wiping is connected with motor by reductor, in the broken sieve of described wiping, is provided with screen cloth, and the lower end of described screen cloth connects turbination hopper; Described polybag is positioned in charging basket, and plastic bag mouth and hopper outlet are tightly connected; Described gas cylinder is connected with escape pipe through pressure-reducing valve, and the gas outlet of described escape pipe is connected with hopper outlet, and stretches to polybag inside, in described gas cylinder, fills inert gas, and described inert gas is argon gas or nitrogen.
Further, described screen cloth is 40-60 order, and preferred screen cloth is 50 orders.
Further, the broken sieve of described wiping is the broken sieve of vibration wiping.
Further, described inert gas is argon gas.
The utlity model has following advantage: the utility model flow to dried compound from top to bottom in the polybag in charging basket, and argon gas in gas cylinder flows from the bottom to top, reverse and go with compound, thereby reduced contacting of compound and air, realized the object that reduces compound oxidation by air, can stabilized product quality.The utility model is simple in structure, easy to operate, practical.
Accompanying drawing explanation
Fig. 1: perspective view of the present utility model;
1. wipe broken sieve, 2. plastic bag, 3. charging basket, 4. gas cylinder, 5. pressure-reducing valve, 6. escape pipe.
The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, a sieve material aerating device, comprises frame, wipes broken sieve 1, polybag 2, charging basket 3 and gas cylinder 4, and the broken sieve of described wiping is positioned at upper rack, described charging basket is positioned at frame lower, and be positioned at wipe broken sieve under, the broken sieve of described wiping is connected with motor by reductor, the broken sieve of described wiping is preferably the broken sieve of vibration wiping, in the broken sieve of described wiping, be provided with screen cloth, described screen cloth is 40-60 order, is preferably 50 orders, and the lower end of described screen cloth connects turbination hopper; Described polybag is positioned in charging basket, is used for placing the compound after sieving, and plastic bag mouth and hopper outlet are tightly connected; Described gas cylinder is connected with escape pipe 6 through pressure-reducing valve 5, the gas outlet of described escape pipe is connected with hopper outlet, and stretch to polybag inside, in described gas cylinder, fill inert gas, described inert gas is argon gas or nitrogen, more than in carbide alloy pressure sintering process, have a large amount of highly purified argon gas, so the utility model is preferentially used high-purity argon gas, escapable cost.
Dried compound sieves through wiping broken sieve, through hopper outlet, enters in polybag, completes flowing from top to bottom.Argon gas in gas cylinder is passed into by hopper outlet through pressure-reducing valve, by wiping broken sieve feeding mouth, discharge, complete flowing from the bottom to top, reverse and go with compound, thereby played, reduce the effect that air contacts with compound, realized the object that reduces compound oxidation by air, can stabilized product quality.Material sealed storage after sieving, in polybag, and is taken out from charging basket.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
Claims (5)
