Description

Technical Field

[0001] The utility model relates to the technical field of smelting slag, in particular to a smelting slag collection device. Background Technique

[0002] The slag of the smelting furnace, also known as furnace slag or molten slag, is a melt floating on the surface of liquid substances such as metals during the pyrometallurgical process. Its composition is mainly oxides (such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), often contains sulfides and entangles a small amount of metals. According to different metallurgical processes, the furnace slag can be divided into smelting slag and refining slag. The smelting slag is the furnace slag formed while obtaining crude metal or matte, while the refining slag is the furnace slag generated during the refining of crude metal (such as steelmaking with pig iron, refining copper from crude copper, etc.).

[0003] The Chinese utility model patent with the publication number CN215176970U discloses a smelting furnace slag collection device. The key points of its technical solution are: including a base, a blanking machine is fixedly arranged at the left end of the base. The blanking machine discharges materials through a blanking port and is communicated with a stirring barrel. An air purifier and a water injection port are arranged at the upper end of the stirring barrel. A stirring blade and a platform are arranged in the stirring barrel. The platforms are arranged in a stepped shape and inclined to the right. The platforms are connected by a filter screen. The rightmost end of the platform is communicated with a discharge port. A water outlet and a discharge port are arranged at the bottom of the stirring barrel. The discharge port is communicated with a water draining machine. A vibration motor is fixedly arranged on the water draining machine. Air holes are arranged on the side and bottom of the water draining machine. A blower is arranged on the corresponding surface of the side air holes. The water draining machine is fixedly arranged on the base through spring columns. This utility model can discharge waste gas and collect slag more reasonably and efficiently.

[0004] However, during the use of this utility model, since a stepped shape is formed between the platform and the filter screen, when filling water into the stirring barrel, the slag and water will first contact the platform. And the multiple platforms form a stepped shape from left to right and downward. At this time, due to the action of water flow and gravity, some slag cannot be filtered and directly enters the water draining machine, affecting the separation effect of metal substances in the slag and not meeting the production requirements. Therefore, a smelting slag collection device is proposed to solve the problems mentioned above. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a smelting slag collection device, which has the advantage of improving the separation of metal substances in the slag, and solves the problem that since a stepped shape is formed between the platform and the filter screen, when filling water into the stirring barrel, the slag and water will first contact the platform. And the multiple platforms form a stepped shape from left to right and downward. At this time, due to the action of water flow and gravity, some slag cannot be filtered and directly enters the water draining machine, affecting the separation effect of metal substances in the slag and not meeting the production requirements.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A melting slag collection device, including a base and a filtration box fixedly connected to the top of the base.

After the sewage inside the filter tank is completely drained, the driving motor drives the eccentric wheel to rotate, which can drive the filter screen to vibrate, and then the metal substances separated from the slag can be transported to the drying box through the connecting pipe. While improving the filtering effect of the slag, it can reduce the impurities in the slag from being collected together with the metal substances.

[0017] 2. The smelting slag collection device drives the stirring rod to rotate by setting a servo motor, which can fully mix the slag and water inside the filter tank, thereby improving the filtering efficiency of the slag, and solving the problem that a step is formed between the platform and the filter screen. When filling water into the stirring barrel, the slag and water will first contact the platform, and the multiple platforms form a stepped shape from left to right and downwards. At this time, due to the action of water flow and gravity, some slag cannot be filtered and directly enters the water drainer, affecting the separation effect of metal substances in the slag and not meeting the production requirements.

A cam 6 is fixedly connected to the output shaft of the driving motor 5. The upper surface of the cam 6 is in contact with the lower surface of the filter net 4. A communicating pipe 7 is fixedly connected between the filter box 2 and the drying box 3 and is in communication.

[0025] Among them, both the left and right sides of the filter net 4 are fixedly connected with positioning sliders extending into the filter box 2. Positioning chutes adapted to the positioning sliders are provided on the inner wall of the filter box 2. On the top of the drying box 3, a dryer body 8 extending into it is fixedly installed. A collection box 9 is slidably connected to the inner bottom wall of the drying box 3.

[0026] It should be noted that a controller is fixedly installed on the front of the filter box 2. The filter net 4 is inclined, which can improve the falling rate of metal substances. By setting the filter net 4, the slag-water mixture can be directly filtered. By setting a drain pipe 17, the filtered sewage can be discharged. When the sewage inside the filter box 2 is completely discharged, by driving the driving motor 5 to drive the cam 6 to rotate, the filter net 4 can be driven to vibrate, and then the metal substances separated from the slag can be transported to the inside of the drying box 3 through the communicating pipe 7. While improving the filtering effect of the slag, it can reduce the impurities in the slag from being collected together with the metal substances.

[0027] In this embodiment, a servo motor 10 is fixedly installed on the top of the filter box 2. A stirring rod 11 extending into the filter box 2 is fixedly connected to the output shaft of the servo motor 10. A steel pipe 12 is fixedly connected to the inner top wall of the filter box 2. A spray head 13 is fixedly installed on one side of the steel pipe 12 close to the filter net 4. The top of the steel pipe 12 is fixedly connected with a water inlet pipe extending to the top of the filter box 2.

[0028] Among them, a guide plate 16 is fixedly connected to the inner bottom wall of the filter box 2. A drain pipe 17 extending into it is fixedly connected to one side of the filter box 2 away from the drying box 3. The shape of the steel pipe 12 is in a shape of a square frame with a loop, and the stirring rod 11 passes through the steel pipe 12. The shape of the guide plate 16 is a right triangle.

[0029] In this embodiment, a feed pipe 15 extending into it is fixedly connected to one side of the filter box 2 away from the drying box 3. A gas purification device 14 communicating with it is fixedly connected to one side of the filter box 2 away from the feed pipe 15. By setting the gas purification device 14, the harmful gases generated inside the filter box 2 can be purified to avoid environmental pollution.

[0030] The working principle of the above embodiments is as follows:

[0031] First, the staff transports the slag mixed with metal substances to the inside of the filter box 2 through the feed pipe 15, and at the same time transports water to the inside of the steel pipe 12, so that the spray head 13 continuously injects water into the filter box 2. The servo motor 10 is started to drive the stirring rod 11 to rotate, so that the slag and water are fully mixed. Subsequently, the sewage will be discharged through the drain pipe 17, and at the same time, the filter screen 4 will filter out the metal substances. At this time, the dryer body 8 and the drive motor 5 are started at the same time. The drive motor 5 drives the filter screen 4 to vibrate, and the metal substances enter the drying box 3. At the same time, the dryer body 8 dries the metal substances.
