Background

In production, the temperature in the melting furnace is about 1600 ℃ and the pressure is about 3 Pa. The front section of the kiln pressure detection pressure guiding pipe is easily ablated and damaged at high temperature under the micro-positive pressure environment. After the broken gas of the pressure guiding pipe leaks, the pressure deviation is transmitted to the pressure transmitter, and the detection result is distorted. Eventually, the pressure in the melting furnace is inconsistent with the actual production condition, and huge potential safety hazards exist in the melting furnace. Therefore, the connecting end of the existing kiln pressure leading-out pipe and the melting furnace is sleeved with a hollow cooling ring, and water is introduced into the cooling ring so as to reduce the temperature of the connecting end of the kiln pressure leading-out pipe; however, due to the large consumption of cooling water, tap water is usually selected, and after the tap water is heated in the cooling ring, scale is formed on the inner wall of the cooling ring, so that the cooling effect of the cooling ring is reduced, and along with the extension of the service time, the connection end of the pressure guiding pipe and the melting furnace is still broken due to high-temperature ablation.

Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-2, to delay the inner wall of the cooling ring from being covered by scale. The utility model provides a novel kiln pressure detection pressure guiding pipe, which comprises a pressure guiding pipe 1 connected to the side wall of a melting kiln, a hollow cooling ring 2 sleeved at the fixed end of the pressure guiding pipe 1, and a water inlet pipe 3 and a water outlet pipe 4 communicated with the interior of the cooling ring 2, wherein a partition plate 9 is arranged in the cooling ring 2, the connecting ends of the water inlet pipe 3 and the water outlet pipe 4 and the cooling ring 2 are distributed on two sides of the partition plate 9, a flow guide plate 8 is arranged on a water flow channel between the water inlet pipe 3 and the water outlet pipe 4 in the cooling ring 2, the flow guide plate 8 is arranged on the inner end wall of the cooling ring 2, and a gap between the flow guide plate 8 and the inner side wall of the cooling ring 2 is gradually decreased along the water flow direction.

Cooling water enters the cooling ring 2 from the water inlet pipe 3, and flows in from the water inlet pipe 3 due to the action of the partition plate 9, flows out from the water outlet pipe 4, exchanges heat with the pressure guiding pipe 1 through the inner side wall of the cooling ring 2, and reduces the temperature of the fixed end of the pressure guiding pipe 1.
