Abstract

The utility model provides a feeding device, which comprises a feeding pipe, a feeding port and a discharging port. The feeding pipe is provided with a bending portion, the feeding port is connected to the upper portion of the feeding pipe, the discharging port is connected to the lower portion of the feeding pipe, and a wear-resistant layer is disposed on one side, which is close to the bottom of the pipe, of the inner wall of the bending portion of the feeding pipe. The feeding device is simple in structure and easy in production and manufacture, and can effectively reduce abrasion to the feeding pipe, thereby prolonging the service life of the feeding device and guaranteeing long-term stable operation of the feeding device.

Description

A kind of feeding device

Technical field

The utility model relates to the feeding device of carrying alloy material in the steel-making storing and transporting system.

Background technology

In the STEELMAKING PRODUCTION process, the feeding device of storing and transporting system is subjected to the restriction of factory building and explained hereafter, and the situation that changed course is turned round appears in feeding device regular meeting.But, when the irregularity of material type causes blanking in the changed course corner with bigger impact, produce severe wear to material pipe is inner, so that impaired place tube wall often is worn through, cause material take place to leak, the normal operation of whole production line has been played restrictive function.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that occur in the prior art, and a kind of feeding device of performance boost is provided.

Feeding device of the present utility model, comprise feed pipe, be connected the inlet point on described feed pipe top and the discharging opening that is connected described feed pipe bottom with bending part, wherein, has wearing layer at the inwall of described feed pipe bending part near pipe one side at the end.

The lower port of described inlet point and the upper port of described feed pipe are equipped with flange connector, and the upper port of described discharging opening and the lower port of described feed pipe are equipped with flange connector, and described inlet point and described discharging opening are connected respectively to the upper and lower of described feed pipe by flange connector.

Described wearing layer is the steel-wire-net reinforced concrete layer.

The thickness of described steel-wire-net reinforced concrete layer is between 8-20mm.

Feeding device of the present utility model is simple in structure, is easy to manufacture, and can effectively alleviates wearing and tearing to feed pipe, thereby prolonged feeding device service life, guarantees its operation steady in a long-term.

Fig. 2 is the A-A cross sectional drawing of Fig. 1.

The specific embodiment

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, demonstrate feeding device of the present utility model.Particularly, feeding device of the present utility model comprises the feed pipe 3 with bending part, the discharging opening 6 that is connected the inlet point 1 on feed pipe 3 tops and is connected feed pipe 3 bottoms.

By flange connector inlet point 1 and feed pipe 3 are coupled together.The upper port of the lower port of inlet point 1 and feed pipe 3 is equipped with flange connector 2, by bolt two flange connectors 2 is fixed together.Similarly, the lower port of the upper port of discharging opening 6 and feed pipe 3 is equipped with flange connector 5, and by bolt two flange connectors 5 is fixed together.Also promptly, inlet point 1 and discharging opening 6 are connected respectively to the upper and lower of feed pipe 3 by flange connector.When feed pipe 3 may wear to can not re-use the time, can turn on the bolt on flange connector 2 and 5, feed pipe 3 and inlet point 1 and discharging opening 6 are broken away from, thus the feed pipe that more renews.

Feed pipe 3 is bendings, and the inwall of the bending part of feed pipe 3 is near having wearing layer 4 on pipe one side at the end.Fig. 2 shows the A-A section among Fig. 1.As shown in the figure, wherein, a side of the inwall of feed pipe 3 has the wearing layer 4 that thickness is h.Preferably, wearing layer 4 is the steel-wire-net reinforced concrete layers that mixed by abrasion-proof concrete and wire net.In addition, the thickness of steel-wire-net reinforced concrete layer should be controlled between the 8-20mm, and is too little as thickness, and then wear-resisting effect is undesirable; Too big as thickness, then can cause the diameter and the unnecessary increase of weight of feed pipe 3.

Steelmaking system is during by feeding device charging of the present utility model, when material during through bending part, because wearing layer 4 is subjected to the direct impact of material to its generation, thereby slowed down the impact that feed pipe 3 tube walls are subjected to.Therefore, because the existence of wearing layer 4, strengthened the impact resistance of feed pipe 3 tube walls, prevented that effectively feed pipe 3 is worn through at bending part, thereby make that whole feeding device can operation steady in a long-term.

Need to prove at last; the above only is a better embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characterictic being equal to of being done replaced or corresponding improvement, still within protection domain of the present utility model.
