Description

Technical Field

[0001] This utility model relates to the field of slag bag drainage production technology, and in particular to a slag bag pumping device. Background Technology

[0002] Slag ladle drainage is a critical step in the metal smelting process, directly impacting equipment safety and operational efficiency. Currently, in the pre-slag receiving stage, the slag ladle is discharged at approximately 1200°C due to the high temperature of the molten slag. Furthermore, because the working environment is outdoors, rainwater often accumulates inside the ladle, resulting in significant water buildup. When this accumulated water reacts with the high-temperature slag, it can cause the ladle to rupture, leading to serious injury to equipment and personnel – a highly dangerous situation.

[0003] In existing technologies, a negative pressure suction structure is deployed into the slag bag via an unwinding structure to extract rainwater. However, since the slag bag contains a large amount of solid waste, including particulate and powdery materials, a filter structure is installed at the end of the negative pressure structure to separate most of the solid waste in order to reduce the difficulty of subsequent solid waste treatment. Designing a filter structure with a smaller pore size can further improve the filtration effect on solid waste. However, filter structures with smaller pore sizes are more prone to clogging, requiring staff to lift and replace the filter structure regularly, which affects the drainage efficiency of the slag bag. In particular, replacing the filter structure during the drainage process disrupts the overall drainage operation and greatly reduces the drainage efficiency of the slag bag. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology by proposing a slag bag pumping device that eliminates the need to remove and replace the filter device, thus ensuring the effective extraction of rainwater and other sewage from the slag bag while greatly improving the overall extraction efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slag bag pumping device includes a pumping platform, an unwinding device at the top of the pumping platform, and a filter device at the end of the unwinding device. The filter device includes a filter cylinder, and a partition component is provided inside the filter cylinder. The partition component abuts against the inner wall of the filter cylinder. The partition component is asymmetrically arranged to divide the filter cylinder into a pumping chamber and a backwashing chamber. A negative pressure pipe is connected to the top of the pumping chamber, and a backwashing pipe is connected to the backwashing chamber. The device also includes a drive component for driving the partition component to rotate.

[0007] Preferably, the backwashing pipe is disposed on the inner wall of the partition assembly near the pumping chamber, and a water pump is disposed inside the backwashing pipe.

[0008] Preferably, the separating component includes an arc-shaped separating plate, both sides of which abut against the inner wall of the filter cylinder.

[0009] Preferably, a first sealing component is fixed to the top of the partition plate, and a second sealing component is fixed to the bottom of the partition plate.

[0010] Preferably, a backwashing chamber is formed between the protruding side of the partition plate and the inner wall of the filter cylinder; a pumping chamber is formed between the concave side of the partition plate and the inner wall of the filter cylinder.

[0011] Preferably, the unwinding device includes an unwinding reel and an unwinding cable, the bottom of which is bolted to the filter device.

[0012] Preferably, the upper end of the filter cylinder is also provided with a cover, which is detachably connected to the filter cylinder.

[0013] Preferably, it also includes a vacuum pump and a separation tank, the separation tank being connected to a negative pressure pipeline via a hose.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] Through the above structural design, the positions of the backwashing chamber and the pumping chamber can be adjusted by controlling the deflection of the partition component. The pumping chamber can be deflected to the non-clogging side after backwashing to continuously pump the mixed liquid in the sludge bag. At the same time, the backwashing chamber is deflected to the clogged side for efficient backwashing. The operation in this way is simple and convenient, without the need to set up two sets of filter devices or remove and replace the filter devices. This ensures the effective extraction of rainwater and other sewage in the sludge bag while greatly improving the overall extraction efficiency. Attached Figure Description

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0024] To address the problems mentioned in the background art, see Appendix Figure 1 -Appendix Figure 5 A slag bag pumping device includes a pumping platform 500, an unwinding device 300 and a filter device 400 located at the end of the unwinding device 300. The filter device 400 is placed at the bottom of the slag bag by the unwinding device 300. The negative pressure device is activated to pump out the rainwater in the slag bag. The filter device 400 can separate the solid waste in the slag bag, prevent the solid waste from mixing with the rainwater, and reduce the difficulty of subsequent rainwater treatment.

[0025] Specifically, the filter device 400 includes a filter cylinder 410, inside which a partition component 420 is provided. The partition component 420 abuts against the inner wall of the filter cylinder 410. The partition component 420 is asymmetrically arranged to divide the filter cylinder 410 into a pumping chamber 4202 and a backwashing chamber 4201. The top of the pumping chamber 4202 is connected to a negative pressure pipe 440, and the backwashing chamber 4201 is connected to a backwashing pipe 424. The device also includes a drive component for driving the partition component 420 to rotate.

[0026] Multiple small-diameter filter holes are opened on the outer surface of the filter cylinder 410, which can adsorb small-sized particulate matter. The negative pressure pipe 440 can continuously pump the liquid in the pumping chamber 4202 and the outside. During the continuous pumping process, particulate matter is blocked in the filter holes on the surface of the filter cylinder 410, affecting the efficiency of continuous pumping.

[0027] To solve this problem, after a certain period of extraction, the separation component 420 is deflected as a whole by the drive component, so that the pumping chamber 4202 changes the suction range. At this time, the backwashing chamber 4201 is opposite to the area of ​​negative pressure suction in the previous moment, and cleaning liquid is pumped into the backwashing chamber 4201 through the backwashing pipe 424 to achieve backwashing of the blocked area.

[0028] The aforementioned drive component can be selected as a motor structure for drive control. The motor structure can be embedded in the bottom or top of the filter cylinder 410. The above is prior art and will not be described in detail here.

[0029] In summary, through the above structural design, the positions of the backwashing chamber 4201 and the pumping chamber 4202 can be adjusted by controlling the deflection of the partition component 420. The pumping chamber 4202 can be deflected to the non-clogging side after backwashing to continuously pump the mixed liquid in the slag bag. At the same time, the backwashing chamber 4201 is deflected to the clogged side for efficient backwashing. The operation in this way is simple and convenient, eliminating the need for two sets of filter devices 400 and the need to remove and replace the filter devices 400. This ensures the effective extraction of rainwater and other sewage from the slag bag while greatly improving the overall extraction efficiency.

[0030] The backwash pipe 424 is located on the inner wall of the partition assembly 420, near the pumping chamber 4202. A water pump is installed in the backwash pipe 424. The water pump can pump the filtered liquid in the pumping chamber 4202 into the backwash chamber 4201 in one direction to increase the internal pressure. As the pressure gradually increases, the substances blocking the filter holes on the surface of the filter cylinder 410 are discharged.

[0031] The separator assembly 420 includes an arc-shaped separator plate 422. Both sides of the arc shape of the separator plate 422 abut against the inner wall of the filter cylinder 410. The protruding side of the separator plate 422 forms a backwash chamber 4201 between itself and the inner wall of the filter cylinder 410. The concave side of the separator plate 422 forms a pumping chamber 4202 between itself and the inner wall of the filter cylinder 410. The arc-shaped separator plate 422 design allows the negative pressure pipe 440 at the top to be constantly located in the pumping chamber 4202 to achieve continuous negative pressure suction. At the same time, it can reduce the space in the backwash chamber 4201, and can increase the internal pressure with less liquid to achieve a better backwashing effect.

[0032] A first sealing component 423 is fixed at the top of the partition plate 422, and a second sealing component 421 is fixed at the bottom of the partition plate 422. The sealing component can be a disc or an asymmetrical ring. The sealing component can be located at the top and bottom to effectively separate the backwashing chamber 4201 and the pumping chamber 4202, so as to avoid liquid crossflow affecting the liquid suction and backwashing effect.

[0033] Specifically, the unwinding device 300 includes an unwinding reel 310 and an unwinding cable 320. The bottom of the unwinding cable 320 is bolted to the filter device 400. The unwinding reel 310 is driven and controlled by a motor to realize the lifting and lowering control of the filter device 400.

[0034] The filter cylinder 410 is also provided with a cover 430 at the upper end. The cover 430 is detachably connected to the filter cylinder 410. Through the above structural design, the filter device 400 can be completely disassembled, and the inside of the filter device 400 can be cleaned regularly to effectively clean some solid waste that cannot be backwashed. The filter cylinder 410 and the cover 430 can be connected by threads to ensure the sealing of the top.

[0035] It also includes a vacuum pump 100 and a separation tank 200. The separation tank 200 is connected to a negative pressure pipeline 440 via a hose. The vacuum pump 100 draws the separation tank 200 into a negative pressure state. At the same time, a valve is installed in the hose. After the filter device 400 descends to the bottom position, the valve is opened to achieve rapid negative pressure extraction. The top and bottom of the separation tank 200 are connected to pipelines. The pipeline at the top discharges the supernatant after sedimentation, and the pipeline at the bottom discharges the precipitated powder solid waste.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
