Description

Technical Field

[0001] The invention belongs to the technical field of water-sealed annular coolers, and in particular relates to a silting device for a water tank of a water-sealed annular cooler. Background Art

[0002] Water-sealed annular coolers effectively cool sintered ore, while offering excellent sealing and strong gas collection capabilities, effectively suppressing visible smoke and dust from escaping. Water-sealed annular coolers primarily utilize a water tank for sealing, replacing traditional mechanical seals, rubber seals, and brush seals. The water-sealed structure offers improved sealing performance.

[0003] The water-sealed structure features an upper water trough that rotates synchronously with the cooler trolley. A fixed sealing plate is placed in the center of the trough on the top hood, creating a water seal by storing water at a certain depth. The cooler utilizes forced air cooling. During the cooling process, dust from the sintered ore escapes with the wind, but is blocked by the water-collecting seal. Some dust settles in the upper water trough. Excessive dust accumulation can form sludge or even compaction in the trough.

[0004] Currently, water-sealed annular cooler troughs are often desilted by adding a bucket wheel to the inner and outer upper troughs. However, in practice, excessive or compacted aggregate in the troughs can hinder bucket wheel operation, leading to high transmission failure rates and the inability of the bucket wheel to dislodge aggregate, resulting in poor desilting results. Furthermore, aggregate removed by the bucket wheel can spill onto the site, impacting the environment. If aggregate buildup in the annular cooler's upper trough is not cleaned for an extended period, the fixed sealing plate on the hood can interfere with the silt, causing deformation and damage. This interference can even affect the normal operation of the annular cooler, significantly impacting both environmental protection and normal production. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a dredging device for a water-sealed ring cooler water tank, which is used to solve the problem in the prior art that the dredging effect of the water-sealed ring cooler water tank is poor and affects the on-site environment.

[0006] To achieve the above-mentioned and other related purposes, the technical solutions of the present invention are as follows:

[0007] A desilting device for a water tank of a water-sealed ring cooler, comprising:

[0008] A compressed air pipe is inserted into the bottom of the sealed water tank. A water supply pipe is connected to the sealed water tank to supply water into the sealed water tank. The compressed air pipe supplies compressed air into the sealed water tank, and utilizes a compressed air bubbling method to stir and mix the sludge in the sealed water tank with water to form a slurry.

[0009] A sedimentation tank is built on one side of the water-sealed ring cooler and is lower in height than the sealed water tank;

[0010] A siphon pipe, one end of which extends into the bottom of the sealed water tank, and the other end of which extends into the sedimentation tank, utilizes the siphon principle to suck the slurry in the sealed water tank into the sedimentation tank.

[0011] Optionally, there are at least two compressed air pipes.

[0012] Optionally, a first valve is provided at both ends of the siphon pipe, a water inlet pipe is connected to the middle of the siphon pipe, and a second valve is provided on the water inlet pipe.

[0013] Optionally, a funnel is connected to the upper end of the water inlet pipe.

[0014] Optionally, the upper end of the sedimentation tank is connected to a clean water pipe, and the clean water pipe is connected to a clean water pump.

[0015] Optionally, the clean water pipeline is connected to a sealed water tank.

[0016] Optionally, a water supply valve is provided on the water supply pipe.

[0017] In the present invention, during the normal production operation of the annular cooler, the aggregates and silt in the water tank of the water-sealed annular cooler can be cleaned to avoid long-term aggregate damage to the sealing plate or interference that causes the annular cooler to stop, thereby eliminating any impact on environmental protection and production. Specifically, water is first supplied to the bottom of the sealed water tank through a water supply pipe, and then compressed air is passed into the aggregates and silt at the bottom of the sealed water tank through a compressed air pipe. The silt in the sealed water tank is stirred and mixed with water using a compressed air bubbling method to form a slurry. Finally, the slurry in the sealed water tank is sucked into the sedimentation tank through a siphon pipe. The slurry is re-precipitated and separated in the sedimentation tank and can be cleaned and recycled. In this solution, the use of the siphon principle reduces the investment in equipment such as slurry pumps, which reduces the cost investment in the slurry transfer process and the amount of maintenance work required after equipment failure; it also greatly reduces the workload of workers. Compared with the existing technology, this solution uses the siphon principle in combination with the air bubbling method to mix the aggregate and sludge into a slurry and then extract it, avoiding the formation of sludge or sludge compaction in the sealed water tank, damage to the sealing plate or interference causing the water sealing ring cooler to shut down.

[0022] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0023] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided to make the disclosure thorough and complete and to fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, like reference numerals represent like components throughout.

[0024] The specific structure of the desilting device for the water tank of the water seal ring cooler in the present invention is combined with reference to Figure 1 The desilting device for a water-sealed ring cooler water tank comprises:

[0025] A compressed air pipe 13 is inserted into the bottom of the sealed water tank 10. The sealed water tank 10 is connected to a water supply pipe 11 for supplying water into the sealed water tank 10. The compressed air pipe 13 supplies compressed air into the sealed water tank 10, and uses a compressed air bubbling method to stir and mix the sludge in the sealed water tank 10 with water to form a slurry;

[0026] The sedimentation tank 20 is built on one side of the water-sealed ring cooler and is lower in height than the sealed water tank 10;

[0027] A siphon pipe 21 has one end extending into the bottom of the sealed water tank 10 and the other end extending into the sedimentation tank 20 , and utilizes the siphon principle to suck the slurry in the sealed water tank 10 into the sedimentation tank 20 .

[0028] Among them, the sealed water tank 10 is a part of the water-sealed ring cooler. The bucket wheel dredging device was removed from the original bucket wheel position of the water-sealed ring cooler, and the siphon pipe 21 and the compressed air pipe 13 were installed at the original bucket wheel position; the sedimentation tank 20 was built on the open space on the ground.

[0029] During the actual implementation process, that is, during the normal production operation of the water-sealed annular cooler, the aggregates and silt in the water tank of the water-sealed annular cooler can be cleaned to avoid long-term aggregate damage to the sealing plate or interference that causes the annular cooler to stop, thereby eliminating any impact on environmental protection and production. Specifically, water is first replenished to the bottom of the sealed water tank 10 through the water supply pipe 11, and then compressed air is passed into the aggregates and silt at the bottom of the sealed water tank 10 through the compressed air pipe 13. The silt in the sealed water tank 10 is stirred and mixed with water using the compressed air bubbling method to form a slurry. Finally, the slurry in the sealed water tank 10 is sucked into the sedimentation tank 20 through the siphon pipe 21. The slurry is re-precipitated and separated in the sedimentation tank 20 and can be cleaned and recycled. In this solution, the use of the siphon principle reduces the investment in equipment such as slurry pumps, which reduces the cost investment in the slurry transportation process and the amount of maintenance work required after equipment failure; it also greatly reduces the workload of workers.

[0030] In some embodiments, there are at least two compressed air pipes 13. For example, Figure 1 As shown, the compressed air pipes 13 have a small diameter and a large number, which can allow more air to be filled into the aggregate and sludge in a denser manner, thereby making the compressed air bubbling method more effective in mixing the sludge and water in the sealed water tank 10 to form a slurry.

[0031] In some embodiments, first valves 22 are provided at both ends of the siphon pipe 21, a water inlet pipe 23 is connected to the middle of the siphon pipe 21, and a second valve 24 is provided on the water inlet pipe 23. For example, Figure 1 As shown, before the siphon pipe 21 is used, the first valve 22 is closed, the second valve 24 is opened, and water is filled into the siphon pipe 21 through the water inlet pipe 23 so that the siphon pipe 21 can be quickly filled. At this time, the second valve 24 is closed and the first valve 22 is opened to form a siphon phenomenon.

[0032] In some embodiments, the upper end of the water inlet pipe 23 is connected to a funnel 25. For example, Figure 1 As shown, the funnel 25 facilitates filling the siphon pipe 21 with water.

[0033] In some embodiments, the upper end of the sedimentation tank 20 is connected to a clean water pipe 26, and the clean water pipe 26 is connected to a clean water pump 27. For example, Figure 1 As shown, the arrangement of the clean water pipe 26 and the clean water pump 27 facilitates the reuse of the clean water formed by precipitation in the sedimentation tank 20.

[0034] In some embodiments, the clean water pipe 26 is connected to the sealed water tank 10. For example, Figure 1 As shown, the clean water recovered from the sedimentation tank 20 is passed into the sealed water tank 10 for reuse.

[0035] In some embodiments, a water supply valve 12 is provided on the water supply pipe 11. For example, Figure 1 As shown, it is convenient to control the water replenishment situation.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
