The main functions of the flow nozzle brick are as follows: controlling the flow rate and velocity of the glass liquid: precisely adjusting the amount and velocity of the glass liquid flowing out of the furnace through its specific shape and size design to meet the requirements of the drawing process and ensure the quality of the glass liquid; effectively reducing impurities and bubbles that may be mixed in during the outflow of the glass liquid to ensure that the glass liquid entering the drawing link has a high purity; maintaining a stable discharge temperature: its material and structure help to keep the temperature of the glass liquid stable when flowing out and avoid adverse effects of temperature fluctuations on the drawing quality.

[0003] The flow nozzle bricks in the prior art are generally in a flat state. When the glass liquid flows out through the flow channel, it is relatively slow. And at the end of the flow, the glass liquid solution flows along the bottom of the brick, resulting in loss of the glass liquid. Therefore, those skilled in the art propose a flow nozzle brick for a drawing tube glass furnace to solve the above problems. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution: A flow nozzle brick for a drawing tube glass furnace, including a brick head, a flow channel is opened at the top of the brick head, a buffer groove is opened inside the brick head, one side of the brick head is fixedly connected to a brick tail, two brick tops are fixedly connected to the top of the brick tail, a pouring port is opened inside the brick tail, a receiving groove is opened inside the brick tail, and a leakage prevention component is arranged outside the brick head, and the leakage prevention component is used to prevent the glass liquid from leaking away along the bottom of the brick head.

[0006] Further, the leakage prevention component includes a discharge port, and the discharge port is opened outside the brick head.

[0007] Further, the discharge port is communicated with the buffer groove, and the flow channel is communicated with the buffer groove.

[0008] Further, a flow blocking block is fixedly connected to the bottom of the brick head.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the end of the brick tail is used to be installed at the discharge position of the drawing tube glass furnace. The brick tail is in an inclined state. When the glass liquid enters from the pouring port, it can flow down quickly, and the inside of the receiving groove can hold more glass liquid. When the glass liquid flows into the buffer groove, it starts to decelerate and can stably flow out from the inside of the material flow channel. Compared with the traditional material flow nozzle brick, the material flow can be faster and more stable.

[0015] 2. In the utility model, the glass liquid flows down from the discharge port through the material flow channel. When the glass liquid decreases, it will be blocked by the flow blocking block to prevent the glass liquid from flowing along the bottom of the brick head, effectively avoiding the loss of the glass liquid.
