Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, specifically to a cooling side sealing seat for a chain grate machine. Background Technology

[0002] During normal production, the high-temperature waste gas at approximately 1100℃ from the top of the chain grate passes through the preheated cooked balls, then circulates through the grate, the upper roller shaft, and the air box to the exhaust drying section II. Due to the high temperature of the circulating air, the side seal of the chain grate also rises, reaching a maximum temperature of 270℃. The distance between the side seal and the upper roller bearing seat is 278mm, and the heat radiation from the side seal is also transferred to the roller bearing seat, causing the bearing seat temperature to reach as high as 110℃, far exceeding the normal operating temperature.

[0005] Preferably, the outer and inner water-cooled walls of the chain grate side sealing seat are provided with retaining rings, and an internal thread hole is provided around the retaining ring, through which a sealing ring is installed.

[0006] Preferably, a water-cooled shaft is provided within the retaining rings formed by the outer and inner water-cooled walls. The water-cooled shaft passes through the chain grate side sealing seat and communicates with the water-cooled cavity within the chain grate side sealing seat. A bearing seat is provided at one end of the water-cooled shaft. The water-cooled shaft is a hollow tube, and a water passage hole is provided at one end of the water-cooled shaft. The water passage hole of the water-cooled shaft communicates with the water-cooled cavity within the chain grate side sealing seat.

[0007] The beneficial effects of this utility model are as follows: This utility model discloses a cooling chain grate side seal seat. By setting water inlet and outlet on the inner and outer water-cooled walls of the chain grate side seal seat, flowing water is introduced through the water inlet and outlet, thereby reducing the temperature of the chain grate side seal seat. At the same time, flowing water is introduced through the water passage hole, thereby reducing the temperature of the water-cooled shaft, ensuring the normal use of the water-cooled shaft and the chain grate side seal seat, and extending their service life.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1 , Figure 2 , Figure 3 The utility model shown is a cooling chain grate side sealing seat 1. One side of the chain grate side sealing seat 1 is provided with an outer water-cooled wall 6 and the other side is provided with an inner water-cooled wall 7. A water-cooled cavity 8 is formed between the outer water-cooled wall 6 and the inner water-cooled wall 7. The lower right part of the outer water-cooled wall 6 is provided with a water inlet 4 and the upper left part of the outer water-cooled wall 6 is provided with a water outlet 5. The cooling water entering through the water inlet 4 is temporarily stored in the water-cooled cavity 8 and then discharged from the water outlet 5. This forms a flowing cooling water that can better reduce the temperature of the chain grate side sealing seat 1. The outer water-cooled wall 6 and inner water-cooled wall 7 of the chain grate side sealing seat 1 are provided with symmetrical retaining rings 2. The retaining ring 2 is provided with internal thread holes around its circumference. The sealing ring 11 is installed through the internal thread holes around the retaining ring 2, which can prevent the cooling water temporarily stored in the water-cooled cavity 8 from leaking. A water-cooled shaft 9 is installed inside the retaining ring 2 of the outer water-cooled wall 6 and the inner water-cooled wall 7. The water-cooled shaft 9 passes through the shaft hole 3 of the sealing ring 11 and passes through the chain grate side sealing seat 1. The water-cooled shaft 9 is connected to the water-cooled cavity 8 inside the chain grate side sealing seat 1. A bearing seat 10 is provided at one end of the water-cooled shaft 9. The water-cooled shaft 9 is a hollow tube. A water passage hole 12 is provided at one end of the water-cooled shaft 9. The water passage hole 12 of the water-cooled shaft 9 is connected to the water-cooled cavity 8 inside the chain grate side sealing seat 1. Cooling water is introduced into the water passage hole 12. The cooling water and the cooling water in the water-cooled cavity 8 are discharged together from the outlet 5 to avoid the temperature of the water-cooled shaft 9 from getting too high, reduce the equipment failure rate, and affect the use.

[0012] During operation, the inlet 4 is connected to the main cooling water pipe of the water-cooled shaft 9. Cooling water is introduced from the inlet 4 and simultaneously from the water passage 12, both entering the water-cooled chamber 8. The outlet 5 is connected to the nearest water-cooled shaft 9 return water tank. The cooling water in the water-cooled chamber 8 is discharged from the outlet 5. Cooling water is continuously introduced from the inlet 4 and the water passage 12. The circulating cooling water simultaneously reduces the temperature of the chain grate side seal 1 and the water-cooled shaft 9, effectively ensuring the stable operation of the chain grate during use, reducing the failure rate, and extending the service life.

[0013] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
