Abstract

The utility model discloses a metal-stream inoculation feeding device which comprises a feeding tube and a hopper fixedly arranged above the feeding tube and communicated with the feeding tube; the feeding tube adopts a hollow cylinder, and a driven wheel is arranged at one end; a central shaft of the driven wheel is inserted in the feeding tube; the central shaft of the driven wheel is fixedly connected with a feeding spiral spring; the feeding spiral spring is accommodated in the feeding tube; the other end of the feeding tube is communicated and connected with a discharge hole; and the driven wheel is connected with a drive wheel of a drive mechanism. The utility model can better control the feeding quantity of inoculants through the feeding of the feeding spiral spring and has the advantages of simple operation and convenient application.

Description

A kind of current-following inoculation pay-off

Technical field

The utility model relates to casting field, particularly relates to a kind of current-following inoculation pay-off.

Background technology

At casting field, the inoculation process development is very fast, and multiple effective inoculation method is arranged in recent years.For producing gray iron casting, select for use suitable inoculation treating method extremely important, determine the key factor of product quality often.Each inoculation treating method all has its advantage, simultaneously certain limitation is arranged also, does not also have a kind of processing method that can adapt to various working conditions so far.Foundry enterprise all should be according to the actual conditions of oneself, by test, and the method for selected the most suitable enterprises characteristics.Processing method just should strictly be controlled technical process once determining, and is stable to guarantee casting quality.

At present extensively the inoculation treating method that adopts mainly contains: breed when tapping a blast furnace, breed when pour into a mould, mould cavity inoculation and breed preceding preliminary treatment.Being also referred to as ladle inoculation (Ladle Inoculation) for first kind of inoculation treating method-breed when tapping a blast furnace, is the inoculation of carrying out when iron liquid self-thermo furnace or holding furnace flow to casting ladle.For this inoculation treating method, the interpolation opportunity and the mode of inovulant are very important, can not inovulant be added in the bottom of sky casting ladle before cast, operation like this, have the part inovulant with the effect of iron liquid before oxidized, and inovulant is easy to entrain into slag, causes its utilization rate to reduce; Be preferably in the back of tapping a blast furnace, the iron liquid measure is about 1/4 o'clock beginning inoculation of the amount of tapping a blast furnace in casting ladle, by quantitative funnel granular inovulant evenly and is dispersedly spread to liquid stream, the processing in 4/5 o'clock that the iron liquid measure is about the amount of tapping a blast furnace in the casting ladle finishes.This operational method can utilize the stirring action of liquid stream to make inovulant be dissolved in high temperature iron liquid fully, improves its utilization rate.Though the pay-off of various interpolation inovulants is arranged at present, generally can not finish the task of interpolation inovulant rapidly and uniformly, often for poorly controlling on interpolation deal, the opportunity of inovulant, thereby directly influence end product quality.

The utility model content

The purpose of this utility model provides a kind of current-following inoculation pay-off, by feed spring screw feeding, can giving of fine control inovulant measure, and simple to operate, it is convenient to use.

In order to reach above-mentioned technique effect, the utility model provides following technical scheme:

A kind of current-following inoculation pay-off, comprise the hopper that a feed pipe and is installed in the feed pipe top and connects with feed pipe, described feed pipe is a hollow circular cylinder, one end is provided with a driven pulley, the central shaft of described driven pulley is inserted in the feed pipe, is connected with a feed helical spring on the described driven pulley central shaft, and described feed helical spring is installed with in feed pipe, the described feed pipe other end connects with a discharging opening and is connected, and described driven pulley is connected with the driving wheel of a driving mechanism.

Further, the central shaft of described driven pulley stretches into the feeding pipe end and is fixed on the feed pipe by bearing seal.

Technique effect of the present utility model is: because the feed helical spring is spiral rotation, therefore, feed is even, the erratic uneven phenomenon of feed can not appear, what of discharge hole for discharge the capacity that simultaneously can be by inovulant in the control hopper and the speed of driving mechanism control, therefore, very convenient and simple control inovulant give amount, utilize the stirring action of liquid stream to make inovulant dissolve in high temperature iron liquid fully, improved its utilization rate, greatly reduced because of breeding the casting defect that failure occurs.

Description of drawings

Fig. 1 is the structural representation of the utility model device.

The specific embodiment

The utility model is described in further detail for the existing accompanying drawings and the specific embodiment:

As Fig. 1 is the structural representation of the utility model device, a kind of current-following inoculation pay-off, comprise the hopper 1 that a feed pipe 2 and is installed in feed pipe 2 tops and connects with feed pipe 2, feed pipe 2 is a hollow circular cylinder, one end is provided with a driven pulley 4, driven pulley 4 is connected with the driving wheel 5 of a driving mechanism, the central shaft 7 of driven pulley 4 stretches into feed pipe 2 ends and is fixed on the feed pipe 2 by bearing seal, be connected with a feed helical spring 3 on driven pulley 4 central shafts 7, feed helical spring 3 is installed with in feed pipe 2, and feed pipe 2 other ends connect with a discharging opening 6 and are connected.

During feed, as long as start driving mechanism, can be motor etc., driving wheel 5 drives driven pulley 4 and rotates, thereby the feed helical spring 3 that drives on the central shaft 7 rotates, like this inovulant in the hopper 1 will the spiral of feed helical spring 3 promote down to move to the direction of discharging opening 6, finally come out to add to the iron liquid from discharging opening 6.

Claims (2)

1. current-following inoculation pay-off, comprise the hopper that a feed pipe and is installed in the feed pipe top and connects with feed pipe, it is characterized in that: described feed pipe is a hollow circular cylinder, one end is provided with a driven pulley, the central shaft of described driven pulley is inserted in the feed pipe, be connected with a feed helical spring on the described driven pulley central shaft, described feed helical spring is installed with in feed pipe, the described feed pipe other end connects with a discharging opening and is connected, and described driven pulley is connected with the driving wheel of a driving mechanism.
2. current-following inoculation pay-off according to claim 1 is characterized in that: the central shaft of described driven pulley stretches into the feeding pipe end and is fixed on the feed pipe by bearing seal.
