Description

A new type of kiln pressure detection and induction pipe

technical field

The utility model relates to the technical field of pressure induction pipes, in particular to a novel pressure induction pipe for kiln pressure detection.

Background technique

In production, the temperature in the furnace is about 1600°C, and the pressure is about 3Pa. The front section of the kiln pressure detection pressure induction pipe is easily damaged by high temperature ablation in a slightly positive pressure environment. After the pressure induction tube is damaged and the gas leaks, the pressure transmitted to the pressure transmitter will deviate, and the detection result will be distorted. In the end, the pressure in the melting furnace does not match the actual production situation, and there is a huge potential safety hazard in the melting furnace. Therefore, the connection end of the existing kiln pressure induction pipe and the furnace will be equipped with a hollow cooling ring, and water will pass through the cooling ring to reduce the temperature at the connection end of the kiln pressure outlet pipe; however, due to the large amount of cooling water, tap water is usually used. After the tap water is heated in the cooling ring, scale will form on the inner wall of the cooling ring, reducing the cooling effect of the cooling ring. With the prolongation of the use time, the connection between the pressure induction pipe and the furnace will still be broken due to high temperature ablation .

Utility model content

Aiming at the deficiencies in the prior art, the utility model provides a new type of kiln pressure detection and induction pipe, which solves the problem in the prior art that the inner wall of the cooling ring at the connection end of the kiln pressure induction pipe and the melting kiln is prone to scaling The problem.

Preferably, the deflector is connected to two end walls of the cooling ring.

Preferably, an access panel is detachably installed on the bottom of the cooling ring.

Preferably, the partition is connected to the access panel.

Preferably, a fixed ring for supporting the water inlet pipe and the drain pipe is set on the pressure induction pipe, and a cylindrical adapter ring is arranged on the fixed ring, and the water inlet pipe and the drain pipe respectively pass through the adapter ring and Fits snugly against the inside wall of the adapter ring.

Compared with the prior art, the utility model has the following beneficial effects:

Through the setting of the partition, the direction of water flow inside the cooling ring is limited, and through the arrangement of the deflector, the guide between the flow deflector and the inner wall of the cooling ring is made, so that part of the water flow will impact the inner wall of the cooling ring, which has a great impact on cooling. The scale attached to the inner wall of the ring has a certain removal effect, thereby delaying the progress of the inner wall of the cooling ring being covered by scale, and prolonging the maintenance cycle of the cooling ring.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the technical solution in the utility model is further described.

As shown in Figure 1-2, the inner wall of the ring is covered with scale to delay cooling. The utility model proposes a new type of kiln pressure detection pressure pipe, including a pressure pipe 1 connected to the side wall of the melting kiln, a hollow cooling ring 2 sleeved on the fixed end of the pressure pipe 1, and a water inlet pipe connected to the inside of the cooling ring 2 3 and drain pipe 4, the cooling ring 2 is provided with a partition 9, the connection ends of the water inlet pipe 3 and the drain pipe 4 and the cooling ring 2 are distributed on both sides of the partition 9, the water inlet pipe 3 and the drain pipe 4 in the cooling ring 2 A deflector 8 is arranged on the water flow channel between them, and the deflector 8 is arranged on the inner end wall of the cooling ring 2, and the gap between the deflector 8 and the inner wall of the cooling ring 2 decreases along the water flow direction.

Cooling water enters the cooling ring 2 from the water inlet pipe 3, and due to the effect of the partition 9, the water in the cooling ring 2 flows in one direction, flows in from the water inlet pipe 3, flows out from the drain pipe 4, and passes through the inner wall of the cooling ring 2 and the The pressure induction pipe 1 exchanges heat to reduce the temperature of the fixed end of the pressure induction pipe 1 . The direction of the water flow in the cooling ring 2 is guided by the deflector 8, and the heated cooling water flows toward the inner side wall of the cooling ring 2 after being diverted, which can wash the inner side wall of the cooling ring 2 to a certain extent and reduce the temperature drop. The amount of scale adhered on the inner wall of the ring 2 can be reduced, and the maintenance cycle of the cooling ring 2 can be extended.

As shown in FIG. 2 , in order to enhance the structural strength of the cooling ring 2 . The deflectors 8 are connected to two end walls of the cooling ring 2 . When cooling the fixed end of the pressure induction pipe 1, the water flow in the cooling ring 2 is faster, and the two ends of the cooling ring 2 are connected through the deflector 8 to increase the strength of the cooling ring 2.

As shown in Figure 1-2, for the convenience of maintenance personnel, the inside of the cooling ring 2 is cleaned. An access panel 5 is detachably installed on the bottom of the cooling ring 2 . An opening is provided at the bottom of the cooling ring 2, and the inspection plate 5 is fixed on the bottom of the cooling ring 2 by bolts to form a seal for the opening at the bottom of the cooling ring 2.
