Description

TECHNICAL FIELD

[0001] The present application relates to the field of glass melting furnace cooling, in particular to a glass melting furnace small furnace stack cooling tuyere. BACKGROUND

[0002] In the glass melting furnace, the small furnace is a kind of combustion device, the small furnace inlet is connected with the regenerator, the small furnace outlet is connected with the breast wall of the melting part through the small furnace stack, and the combustion-supporting air enters the small furnace through the regenerator, mixes with the fuel at the small furnace outlet, and then burns in the melting part. The small furnace stack is located at the junction of the small furnace and the breast wall, where the temperature is high, and the refractory material is severely eroded by high temperature and the space atmosphere of the melting part. If the small furnace stack brick does not contact closely with the breast wall, it is easy to be washed and burned by the flame. In addition, the high temperature continuously radiated outward during the daily production of the melting furnace will reduce the service life of the steel structure of the melting furnace. Therefore, continuous blowing cooling is needed at the junction of the side of the small furnace stack of the glass melting furnace and the breast wall.

[0003] However, the traditional small furnace stack cooling tuyere is in the shape of a circular tube, which must be made separately from thin steel plates before installation. The manufacturing process is relatively complicated. In addition, after the traditional small furnace stack cooling tuyere is made separately, it needs to be installed at the same time as the construction of the melting furnace steel structure. However, due to the fact that the construction of the melting furnace steel structure and the installation of the melting furnace ventilation system belong to the work scope of different construction personnel, it is easy to miss the operation of synchronously installing the tuyere during the construction of the melting furnace steel structure. When the steel structure construction is completed, due to the limited space, it is difficult to install the tuyere at this time, or the tuyere cannot be normally installed. SUMMARY

[0004] In view of the above-mentioned shortcomings of the related art, the purpose of the present application is to provide a glass melting furnace small furnace stack cooling tuyere to solve the problems of complicated manufacturing process of the cooling tuyere and difficult or impossible normal installation of the tuyere due to missing synchronous installation of the tuyere in the related art.

[0005] To achieve the above-mentioned purposes and other related purposes, the present application provides a glass melting furnace small furnace stack cooling tuyere, one side of the small furnace stack is provided with a small furnace column, the small furnace column is provided with a top plate, a bottom plate and a side plate, the top plate and the bottom plate are arranged in an upper and lower spaced manner, the upper and lower ends of the side plate are connected to the top plate and the bottom plate respectively, and the left and right ends of the side plate are connected to the small furnace column. The small furnace column, the top plate, the bottom plate and the side plate form a tuyere, the tuyere is connected with a fan, the side plate is provided with an air outlet, and cooling air blows to the small furnace stack through the air outlet.

[0006] Optionally, the top plate is provided with a through hole, a circular tube is connected at the through hole, one end of the circular tube away from the through hole is connected with a metal hose, and the end of the metal hose away from the circular tube is connected with the fan through a hard pipe.

[0024] As Figure 1 and Figure 2 As shown in the embodiments, a glass melting furnace small stack cooling tuyere is provided, wherein a small stack 1 is arranged at the outlet of the small furnace, the small stack 1 is connected with the side wall 2 of the small furnace, and the small stack 1 is used to connect the side wall 2 of the small furnace and the breast wall 3. Two small furnace columns are arranged on the two sides of the small furnace respectively, and the two small furnace columns are used to blow cooling air to the small stack 1.

[0025] The tuyere of this embodiment is arranged based on the structure of the small furnace column. The small furnace column is an I-beam, specifically including two horizontal plates 4 and a vertical plate 5. The vertical plate 5 is perpendicular to the two horizontal plates 4 and connected to the two horizontal plates 4 at both ends. A top plate 6, a bottom plate 7 and a side plate 8 are also provided between the two horizontal plates 4. The top plate 6 and the bottom plate 7 are spaced apart from each other. Three side edges of the top plate 6 are welded and fixed to the two horizontal plates 4 and the vertical plates 5 respectively. Three side edges of the bottom plate 7 are welded and fixed to the two horizontal plates 4 and the vertical plates 5 respectively. The side plates 8 are vertically arranged. The fourth side edge of the top plate 6 and the fourth side edge of the bottom plate 7 are welded and fixed to the side plates 8. The left and right ends of the side plates 8 are welded and fixed to the two horizontal plates 4 respectively. At this time, the two horizontal plates 4, the vertical plates 5, the top plate 6, the bottom plate 7 and the side plates 8 are partially surrounded by the small furnace columns to form a rectangular air nozzle. The top plate 6 and the bottom plate 7 are the top and bottom of the air nozzle respectively. The two horizontal plates 4, the vertical plates 5 and the side plates 8 constitute the four sides of the air nozzle.

[0026] A through hole 61 is formed in the top plate 6. A round tube, for example, 100 mm in diameter and 100 mm in length, is welded to the through hole 61. A flange is attached to the end of the round tube, which is then connected to a metal hose. The end of the metal hose, away from the round tube, is connected to the fan via a rigid tube. The fan then delivers cooling air to the nozzle through the rigid tube, the metal hose, and the round tube.

[0027] An air outlet is provided on the side panel 8. The air outlet is in the shape of an elongated strip and has a width of 20 mm. The air outlet is vertically arranged, and the distance between the upper and lower ends of the air outlet and the top plate 6 and the bottom plate 7 is 50 mm.

[0028] like Figure 2 and Figure 3 As shown, a rectangular deflector 9 is welded to the side panel 8 and connected to the long side of the air outlet away from the breast wall 3. The deflector 9 is 50 mm wide and the same length as the air outlet. The deflector 9 is welded to the side panel 8 at a 60° angle and points toward the breast wall 3.

[0029] A fan-shaped plate 10 is respectively arranged between the upper and lower short sides of the guide plate 9 and the side plate 8. The radius of the fan-shaped plate 10 is the same as the width of the guide plate 9, and the central angle of the fan-shaped plate 10 is 60°. This arrangement can ensure that the cooling air blown out from the air outlet is concentrated on the brick joints between the breast wall 3 and the small furnace side wall 2.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
