Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of the sintering process ring cooler machine in the metallurgical industry, in particular to a self-adaptive non-powered ring cooler upper water tank purification device and method thereof. BACKGROUND

[0002] The ring cooler is a device used to cool the finished sintered ore in the sintering process and is an important device indispensable in the entire sintering process. With the continuous upgrading of the ring cooler device, the water-sealed ring cooler has become the mainstream form of the ring cooler today. While its air leakage rate is reduced, some drawbacks also arise, such as the cleaning problem of the upper water tank, which has once plagued various steel enterprises. Because dust and bulk ore are blown into the upper sealing water tank of the ring cooler during equipment operation, the upper water tank is often half water and half mud, and in severe cases, it even affects normal production.

[0003] The existing technical means has the following defects and drawbacks: complex structure and frequent failures: most devices are equipped with a dredging pump, which is a failure point itself and has a high cost and complex supporting facilities; unable to adapt to the deviation of the ring cooler: most devices are fixed at a certain point, and as the ring cooler deviates (the deviation of the ring cooler is a phenomenon that cannot be avoided and almost exists), the targeting of the device becomes poor.

[0004] The patent for utility model with publication number CN 219284002 U discloses a ring cooler upper water tank dredging device, which comprises a sludge pump, a sewage pipe, a filter water tank, and a clean water pipe. The sludge pump is arranged in the upper water tank but does not rotate with the upper water tank. The filter water tank is composed of a sewage tank, a clean water tank, and a filter screen, and the sewage tank and the clean water tank are separated by the filter screen. The outlet of the sludge pump is connected to the water inlet end of the sewage pipe, and the water outlet end of the sewage pipe extends into the sewage tank. One end of the clean water pipe is connected to the clean water tank, and the other end is connected to the upper water tank. The sludge pump introduces the sewage containing sludge in the upper water tank into the sewage tank, and then the sewage is filtered through the filter screen and enters the clean water tank. The water in the clean water tank is returned to the upper water tank for recycling, which has a large treatment capacity, high dredging efficiency, convenient operation, low cost, and can meet the dredging requirements of the upper water tank. However, the device has poor self-adaptability, and as the ring cooler deviates, the position and shape of the upper water tank will change, affecting the use of the sludge pump. In addition, the sludge pump and its supporting equipment have a high cost and are complex, making maintenance inconvenient. SUMMARY

[0005] To overcome the defects of the prior art, the technical problem solved by the present application is to provide a self-adaptive non-powered ring cooler upper water tank purification device and method thereof.

[0034] The specific embodiments of the present application will be further described below in conjunction with the accompanying drawings:

[0035] See Figures 1 to 5 The present application relates to a self-adaptive non-powered upper water tank purification device of a ring cooler, which comprises a hook 4, a connecting chain 5, a mud cleaning box 6, a reset roller 7, an anti-wear track 8, and a mud storage device 9. The hook 4 is fixedly arranged on the plugboard 2 of the upper water tank, one end of the connecting chain 5 is hung on the hook 4, and the other end is fixedly connected with the mud cleaning box 6. The reset roller 7 is fixedly arranged on both sides of the mud cleaning box 6 and can contact the side wall of the upper water tank 1. The anti-wear track 8 is arranged at the bottom of the upper water tank 1 and is arranged in a ring shape along the upper water tank 1. The bottom of the mud cleaning box 6 contacts the anti-wear track 8. The mud storage device 9 is fixedly arranged on the trolley fence 3 of the ring cooler, and the bottom opening of the upper water tank 1 is in communication with the mud storage device 9.

[0036] The mud cleaning box 6 is a box structure with a bottom opening and a side opening, the side opening is opposite to the rotation direction of the upper water tank 1, and the bottom opening contacts the anti-wear track 8.

[0037] The connecting chain 5 can be a flexible chain, and its length should not be too short. Only when the length reaches a certain value, the connecting chain 5 can be attached to the plugboard 2, so that the mud cleaning box of the device is located in the tangential direction of the ring-shaped plugboard 2 (i.e. the mud cleaning box 6 is located in the middle position of the upper water tank 1 and does not interfere with the side wall of the upper water tank 1), and the length of the connecting chain 5 is 200-300 mm, which is the best. When the device is working normally, the connecting chain 5 is hung on the hook 4, but when the device is stuck due to unexpected obstacles, the hook 4 can be bent and deformed, so that the whole device falls off, thereby ensuring the normal operation of the ring cooler.

[0038] The self-adaptive non-powered upper water tank purification device of the ring cooler further comprises a counterweight 10. The counterweight 10 is fixedly connected with the mud cleaning box 6.

[0039] The number of the sludge storage devices 9 is four or more, and they are evenly distributed on the bottom of the upper tank 1. The sludge storage device 9 comprises a sludge storage tank 91, a sludge discharge pipe 92 and a sludge discharge valve 93. The sludge storage tank 91 is a conical structure with a cross section gradually narrowing from top to bottom. The sludge storage tank 91 is fixedly arranged on the trolley apron 3 of the ring cooler, and the top opening of the sludge storage tank 91 is communicated with the bottom of the upper tank 1. The bottom opening of the sludge storage tank 91 is communicated with one end of the sludge discharge pipe 92, and the other end of the sludge discharge pipe 92 is connected with an external sludge transfer or treatment device. The sludge discharge pipe 92 is provided with the sludge discharge valve 93. The sludge discharge valve 93 is a pneumatic sludge discharge valve or an electric sludge discharge valve. The sludge discharge pipe 92 is a flexible pipe.

[0040] The top opening of the sludge storage tank 91 is provided with an anti-falling track 11, and the surface of the anti-falling track 11 is slightly lower than the upper surface of the anti-abrasion track 8. The two form a double insurance to avoid the sludge removal box 6 from falling into the sludge storage tank 91.

[0041] An adaptive non-powered ring cooler upper tank purification method comprises the following steps:

[0042] (1) The upper tank 1 of the ring cooler rotates with the trolley apron 3, and the plug plate 2 of the upper tank is static. With the rotation of the upper tank 1, the sludge removal box 6 moves relative to the upper tank 1, and at the same time, the bulk material and sludge in the upper tank 1 are collected in the sludge removal box 6;

[0043] (2) During the rotation of the upper tank 1, when the top opening of the sludge storage tank meets the sludge removal box 6, the bulk material and sludge collected by the sludge removal box 6 will fall into the sludge storage tank 91 through the bottom of the upper tank;

[0044] (3) The sludge discharge valve 93 is opened regularly, and the bulk material and sludge in the sludge storage tank 91 are discharged;

[0045] (4) When the ring cooler deviates, causing the plug plate 2 of the upper tank to not be located in the center of the upper tank 1, the reset roller 7 on the sludge removal box 6 will contact the sidewall of the upper tank 1 to keep the sludge removal box 6 in the center of the upper tank 1 without interfering with the sidewall of the upper tank 1.
