Description

Automatic discharging material tank with conical valve

Technical Field

The utility model belongs to the field of smelting equipment for iron alloy submerged arc furnaces, in particular to a cone valve automatic discharging material tank.

Background

In the prior art, in the smelting production link of an iron alloy submerged arc furnace, the problems of the feeding material tank on the top stock bin of the submerged arc furnace at present mainly include the increase of the manufacturing cost and the inconvenience of the use of equipment. 1. The material loading bucket adopts the form of lateral wall biax handling from the handling form of material bucket, must utilize longmen hoist 9 just can realize the handling of material bucket, and the problem that this mode brought is: firstly, a set of auxiliary hoisting equipment is added, so that the manufacturing cost is increased; secondly, the gantry crane 9 has a certain use height, so the ore furnace feeding system needs to be designed with consideration of increasing the heights of a factory building and a crane, and the manufacturing cost is increased. 2. The mode of unloading from the material jar is that material jar lower part installation activity taper valve, and the taper valve action relies on central fore-set 10 among the material jar strutting arrangement, and central fore-set 10 top moves the taper valve action back and opens the discharge opening and unload in the time of the material jar descends, and the problem that this mode brought is: firstly, during discharging, because the material tank is still in a hanging state when the central top column 10 pushes the conical valve to act, the material tank is not completely fixed through the material tank bracket, and the danger of shaking of the material tank and unhooking of a crane exists; secondly, a central top column 10 discharging device is added between the charging bucket and the furnace top bin, so that the manufacturing cost is increased, and the system height is increased (see figure 2). And the lower part of the other charging bucket is independently provided with a discharge valve, and the action form of the valve is manually controlled. The problems with this approach are: firstly, manual control is needed, labor cost is increased, and production is safe and unreliable; second, the valve height occupies the system design height.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the aforesaid not enough and provide a safe in utilization, convenient cone valve automatic discharge material jar of unloading.

The technical solution of the utility model is that: the utility model provides a cone valve automatic discharge material jar, includes the material jar body, and there is the cone valve of unloading material jar body bottom, has central jib in the material jar body, and the cone valve is connected to central jib lower extreme, and the internal central jib of its characterized in that material jar upwards stretches out the material jar body, and central jib upper portion has a jack-up rings, and central jib and the internal horizontal more than one of material jar that sets up of more than one support cover carry out central location and swing joint, and the back has the disk seat that prevents it to shift up on the cone valve.

The utility model has the advantages that: 1. by adopting single-shaft hoisting, the use of a gantry lifting hook is reduced, the investment is reduced, and the danger of easy unhooking during the material sending and discharging of the material tank is avoided. 2. This material jar design adopts hoist control cone valve automatic discharge form, 1 people of hoist operating personnel alright realize the control of unloading, easy operation is practical. 3. The unloading conical valve is attached to and sealed with the valve seat during lifting, heavy sealing and automatic unloading are guaranteed, wear-resistant ZG materials are adopted, the valve body is simple in structure, and production and manufacturing are simple. The thickness of the contact surface of the valve body is more than 40mm, the wear-resisting strength is high, and the service life is long.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic view of the structure of the present invention.

Fig. 2 is a schematic view of the structure of a bucket in the prior art.

Detailed Description

Referring to fig. 1 and 2, the names of the components are as follows: the device comprises a material tank body 1, a central suspender 2, a discharge conical valve 3, a valve seat 4, a hoisting ring 5, a support sleeve 6, a furnace top bin 7, a material tank support seat 8, a gantry hook 9 and a central support pillar 10.

Referring to fig. 1, the automatic cone valve discharging tank comprises a tank body 1, a discharging cone valve 3 is arranged at the bottom of the tank body 1, a central boom 2 is arranged in the tank body 1, and the lower end of the central boom 2 is connected with the cone valve 3. A central suspension rod 2 in the material tank body 1 extends upwards to form the material tank body 1, a hoisting ring 5 is arranged at the upper part of the central suspension rod 2, the central suspension rod 2 is centrally positioned and movably connected with two supporting sleeves 6 transversely arranged in the material tank body, and a valve seat 4 for preventing the conical valve 3 from moving upwards is arranged on the upper back surface of the conical valve.

The upper portion and the lower part of the material tank body 1 are designed in a tapered mode, the middle portion of the material tank body is designed in a circular mode, and the using strength is guaranteed while the using amount of steel is reduced.

The upper part of the material tank body 1 is provided with a material conical receiving hopper, so that leakage in the material loading process can be reduced as much as possible.

A material tank supporting seat 8 is arranged outside the conical body at the lower part of the material tank body 1 and used for placing the material tank body 1.

The material tank body 1 adopts a single-shaft hoisting mode of a central hoisting rod 2, an annular hoisting ring 5 is designed at the upper part of the central hoisting rod 2 and is used for hoisting by a crane, and the lower part of the central hoisting rod is connected with a discharge conical valve 3 through a nut to form a whole. The middle end of the central suspender 2 is positioned with the internal supporting sleeve 6 of the charging bucket body 1 and moves up and down. The discharge conical valve 3 and the valve seat 4 are both made of wear-resistant ZG materials, the thickness of a valve body contact surface is more than 40mm, and the discharge conical valve has the characteristic of long service cycle.

The using method comprises the following steps: during lifting, the crane is connected with the annular lifting ring 5 to lift the central lifting rod 2, the discharging conical valve 3 connected with the lower part of the central lifting rod 2 is tightly attached to the valve seat 4, the discharging opening is closed, and the whole material tank body 1 is lifted at the same time. The crane lifts the material tank body to the upper part of the furnace top bin 7, after the material tank supporting seat 8 of the material tank body 1 is in butt joint with the supporting platform of the furnace top bin 7, a crane hook is issued, meanwhile, the central boom 2 and the discharging conical valve 3 at the lower part of the material tank body 1 move downwards, a discharging port of the material tank is opened, and materials enter the furnace top bin 7.

The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
