Description

Technical Field

[0001] This utility model relates to the technical field of cooling water tanks for slag discharge machines, and in particular to a water replenishment system for cooling water tanks of slag discharge machines. Background Technology

[0002] A slag remover, also known as a slag scooping machine, is a device specifically designed to process high-temperature slag generated during industrial production. Its main function is to safely and effectively convert high-temperature slag into solid particles that are easier to process later through cooling and granulation.

[0003] Currently, the common method for cooling slag in slag removal machines is water cooling—that is, high-temperature slag is discharged into a cooling water tank for cooling, and then the slag is removed from the cooling water tank by a slag removal mechanism and sent to the next process. During the cooling process, a large amount of water in the cooling water tank will evaporate; therefore, a water replenishment tank needs to be installed to replenish the cooling water tank.

[0004] However, due to the existing integrated straight-through structure of the water supply tank and cooling water tank, and the high silt content in the cooling water of the slag discharge machine, the traditional straight-through water supply method has the following problems:

[0005] High silt content in the cooling water causes it to flow back into the makeup water tank, where it accumulates and cannot be drained. Over time, the deposited silt blocks the connection between the makeup water tank and the cooling water tank, preventing the water level in the makeup water tank from adjusting to changes in the cooling water tank's level, thus rendering the makeup water system ineffective. When the slag remover's makeup water system malfunctions, situations of water shortage or overfilling may occur. When water is insufficient, the slag in the cooling water tank cannot be cooled, and fine ash from the slag will fly everywhere, polluting the environment. When the tank is overfilled, the cooling water (containing heavy metals, silt, etc.) in the makeup water tank will overflow onto the ground, polluting the environment. Utility Model Content

[0006] The purpose of this invention is to provide a water replenishment system for the cooling water tank of a slag discharge machine, which can solve the defect of silt and sand accumulation in the water replenishment tank and its inability to be discharged, thereby ensuring the continuous and normal operation of the water replenishment system.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is: a water replenishment system for a slag discharge machine cooling water tank, including a water replenishment tank with an integral straight-through structure with the cooling water tank. The water replenishment tank and the cooling water tank are separated by a perforated filter plate, and a funnel-shaped sedimentation section is connected to the bottom of the water replenishment tank. The bottom of the sedimentation section is provided with a return mechanism for conveying the sediment-water mixture in the sedimentation section to the cooling water tank.

[0008] As a further improvement of this utility model, it also includes a water supply pipe that is vertically installed on the inner wall of the water supply tank and whose output end faces the sediment deposition area.

[0009] As a further improvement of this utility model, the input end of the water replenishment pipe is connected to the output end of the main water pipe, and the main water pipe is equipped with a water replenishment electric valve for controlling its opening / closing; the water replenishment tank is also equipped with a float-type liquid level gauge, and both the float-type liquid level gauge and the water replenishment electric valve are electrically connected to a frequency converter control cabinet.

[0010] As a further improvement of this utility model, the main water pipe is also provided with a manual water supply valve for controlling its opening and closing.

[0011] As a further improvement of this utility model, there are two water supply pipes, and the two water supply pipes are arranged opposite to each other on the inner walls of the water supply tank.

[0012] As a further improvement of this utility model, the reflux mechanism includes a reflux pipe, and the reflux pipe is equipped with a suction pump that is electrically connected to the frequency converter control cabinet.

[0013] As a further improvement of this utility model, a suction pump inlet valve for controlling the opening / closing of the inlet pipe is installed on the return pipe on the input side of the suction pump; a drain pipe is also connected to the return pipe on the inlet side of the suction pump inlet valve, and a drain valve for controlling its opening / closing is installed on the drain pipe.

[0014] As a further improvement of this utility model, the lowest filter hole on the perforated filter plate is at least 20mm away from the bottom of the cooling water tank.

[0015] Beneficial effects

[0016] Compared with the prior art, the advantages of the water replenishment system for the cooling water tank of the slag discharge machine of this utility model are as follows:

[0017] 1. In this system, large particles of slag are filtered through a perforated filter plate, and small particles of slag are collected and returned using a funnel-shaped sediment deposition section and a reflux mechanism. This prevents excessive sediment deposition from clogging the connection between the water supply tank and the cooling water tank. Thus, this water supply system solves the problem of sediment deposition in the existing water supply tank that cannot be discharged, thereby ensuring the continuous and normal operation of the water supply system and avoiding water shortage or overfilling.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Example:

[0026] The specific embodiments of this utility model are as follows: Figure 1 As shown, a water replenishment system for a slag discharge machine cooling water tank includes a water replenishment tank 2 with an integral, straight-through structure with the cooling water tank 1. The water replenishment tank 2 is separated from the cooling water tank 1 by a perforated filter plate 3, and a funnel-shaped sediment deposition section 4 is connected to the bottom of the water replenishment tank 2. The bottom of the sediment deposition section 4 is equipped with a return mechanism for conveying the sediment-water mixture in the sediment deposition section 4 back to the cooling water tank 1.

[0027] When the system is in use, the scalding hot slag is directly discharged into cooling water tank 1 for cooling. Then, the slag is removed from cooling water tank 1 by a slag removal mechanism and sent to the next process. During this process, the cooling water in cooling water tank 1 will evaporate, causing the water level in cooling water tank 1 to drop. At this time, water from makeup water tank 2, which is directly connected to cooling water tank 1, will automatically flow into cooling water tank 1 to replenish the cooling water until the water levels in cooling water tank 1 and makeup water tank 2 are equal.

[0028] In this system, a perforated filter plate 3 is installed between the makeup water tank 2 and the cooling water tank 1 to prevent large particles of slag from entering the makeup water tank 2. Simultaneously, a funnel-shaped sediment deposition section 4 is connected to the bottom of the makeup water tank 2. Even if small particles of sediment enter the makeup water tank 2 and deposit, they will first gradually settle in the sediment deposition section 4, preventing immediate blockage of the connection between the makeup water tank 2 and the cooling water tank 1. Furthermore, through a reflux mechanism, the system can return the small particles of sediment deposited in the sediment deposition section 4 to the cooling water tank 1, further preventing excessive sediment deposition in the sediment deposition section 4 from clogging the connection between the makeup water tank 2 and the cooling water tank 1.

[0029] Therefore, this water replenishment system solves the problem of sediment buildup in existing water replenishment tanks that cannot be drained, thus ensuring the continuous and normal operation of the water replenishment system and avoiding water shortages or overfilling.

[0030] To prevent insufficient cooling water in the water supply tank 2, the system also includes a water supply pipe 5 vertically installed on the inner wall of the water supply tank 2, with its output end facing the sediment deposition section 4. Water supply through the water supply pipe 5 ensures that the water level in the water supply tank 2 does not fall below the warning line, thus allowing the entire system to operate continuously and normally. Furthermore, the output end of the water supply pipe 5 facing the sediment deposition section 4 allows the impact force of the water during water supply to agitate the sediment deposited in the sediment deposition section 4, preventing the sediment from hardening and allowing the return flow mechanism to smoothly remove the sediment, ensuring the cleanliness of the water supply tank 2. In this embodiment, to further improve the agitation effect on the sediment during water supply, there are two water supply pipes 5, which are arranged opposite each other on the inner walls of the water supply tank 2.

[0031] Meanwhile, the input end of the water replenishment pipe 5 is connected to the output end of the main water pipe 51, and the main water pipe 51 is equipped with a water replenishment electric valve 52 for controlling its opening and closing. The water replenishment tank 2 is also equipped with a float-type level gauge 21, and both the float-type level gauge 21 and the water replenishment electric valve 52 are electrically connected to a frequency converter control cabinet. This design enables automatic water replenishment to the water replenishment tank 2 without excessive manual intervention, thus saving labor and improving the automation level of the entire system. Of course, in order to allow manual intervention in the opening and closing of the water replenishment pipe 5 in special circumstances, the main water pipe 51 is also equipped with a water replenishment manual valve 53 for controlling its opening and closing. Note that this water replenishment manual valve 53 is generally in the normally open state.

[0032] Furthermore, regarding the specific components of the return mechanism, it includes a return pipe 43, and a suction pump 44 electrically connected to the frequency converter control cabinet is mounted on the return pipe 43. This design allows the control of the suction pump 44 to be incorporated into the automatic control of the frequency converter control cabinet, thereby further improving the automation level of the entire system.

[0033] In this embodiment, a suction pump inlet valve 45 for controlling the opening and closing of the return pipe 43 on the input side of the suction pump 44 is installed on the return pipe 43. A drain pipe 41 is also connected to the return pipe 43 on the inlet side of the suction pump inlet valve 45, and a drain valve 42 for controlling its opening and closing is installed on the drain pipe 41. This design is to facilitate cleaning of the water replenishment system when needed.

[0034] It is important to note that:

[0035] Because the bottom of the slag deposited in cooling water tank 1 contains a large amount of mud and sand, in order to prevent this part of the small particles of mud and sand from flowing into the makeup water tank 2, the bottommost filter hole on the perforated filter plate 3 is at least 20mm away from the bottom of cooling water tank 1.

[0036] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
