Description

Technical Field

[0001] The utility model relates to the technical field related to fuming furnaces, in particular to a high-efficiency slag discharge device for fuming furnaces. Background Art

[0002] The slag produced in the fuming furnace has high temperature and toxic gases. Direct discharge is not conducive to storage and pollutes the environment. It needs to be water-quenched and cooled before water-slag separation. Therefore, a receiving tower is needed for cooling. The existing receiving tower is generally designed as a closed rectangular structure with a length*width*height (4000*400*300mm) for dehydration of the slag trough of the rotary drum. Common problems in the production process are as follows: 1. When the slag volume of the fuming furnace is large, and the outlet of the slag trough of the receiving tower is small, the water-quenched slag cannot flow out in time, and the slag trough of the receiving tower is too small to be discharged in time. 1. It is easy to cause slag blockage in the receiving tower, affecting production continuity; 2. In order to avoid slag blockage in the receiving tower during slag discharge, it is necessary to manually use a blocking rod to control the slag discharge amount of the fuming furnace, which prolongs the slag discharge time of the fuming furnace and reduces production efficiency; 3. If the slag flushing trough is blocked during slag discharge in the normal production of the fuming furnace, the fuming furnace needs to be changed to bypass slag discharge. When the driving crane grabs the slag, part of the slag with high Zn content in the water slag pool will be mixed, which will affect the detection and analysis results of slag zinc when sampling; 4. When the fuming furnace is blocked in the receiving tower, the cleaning intensity is high and the safety hazard is great. Utility Model Content

[0003] Based on this, the purpose of the utility model is to provide a high-efficiency slag discharge device for a fuming furnace to solve the technical problems raised in the above background.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency slag discharge device for a fuming furnace, comprising a receiving tower and a dehydration drum, wherein a slag discharge chute is connected to the side of the receiving tower, a slag discharge port is arranged on one side of the bottom, and the slag discharge port is connected to the dehydration drum through a slag flushing trough, a plurality of high-pressure nozzles are installed on the side and top of the slag flushing trough, and a plurality of high-pressure nozzles are installed on the side of the receiving tower near the bottom.

[0005] Furthermore, a smoke exhaust pipe is connected to the top of the receiving tower, and a plurality of sprinkler heads are provided inside the receiving tower near the smoke exhaust pipe.

[0006] Furthermore, a bypass chute is provided on one side of the receiving tower.

[0007] Furthermore, the slag flushing groove is a sealing structure.

[0008] The utility model installs a plurality of high-pressure nozzles on the bottom side of the receiving tower and the side and top of the slag flushing trough. When slag is accumulated at the bottom of the receiving tower or in the slag flushing trough and cannot be discharged, high-pressure flushing can be performed by connecting the high-pressure nozzles with a high-pressure pump to clear the slag. There is no need to stop work for clearing, which not only reduces labor intensity and safety hazards of cleaning, but also improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0011] The following describes an embodiment of the utility model based on its overall structure.

[0012] like Figure 1 As shown, the utility model includes a receiving tower 1 and a dewatering drum 2. A slag discharge chute 5 is connected to the side of the receiving tower 1, and a slag discharge port is provided on one side of the bottom thereof. The slag discharge port is connected to the dewatering drum 2 through a slag flushing trough 3. The slag flushing trough 3 is a sealed structure. Multiple high-pressure nozzles 4 are installed on the side and top of the slag flushing trough 3. Multiple high-pressure nozzles 4 are installed on the side of the receiving tower 1 near the bottom. A smoke exhaust pipe 7 is connected to the top of the receiving tower 1, and multiple spray heads 6 are provided near the smoke exhaust pipe 7 inside the receiving tower 1. A bypass chute 8 is also provided on one side of the receiving tower 1.

[0013] The working principle of this utility model:

[0014] The slag discharged from the flue gas furnace enters the receiving tower 1 through the slag chute 5, and the multiple spray heads 6 on the top of the receiving tower 1 spray the slag to cool it down. The smoke generated after the slag is sprayed is discharged through the smoke exhaust pipe 7. The cooled slag is mixed with water to form water slag and discharged through the discharge port, and is discharged to the dehydration drum 2 through the slag flushing trough 3 for water-slag separation. When the slag is accumulated at the bottom of the receiving tower 1 or in the slag flushing trough 3 and cannot be discharged, it can be dredged by high-pressure flushing connected to the high-pressure spray head 4 through a high-pressure pump without stopping work for dredging, which not only reduces the labor intensity and safety hazards of cleaning, but also improves work efficiency.

[0015] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
