[0003] Single-layer filter devices have some limitations when processing slag slurry. They can mainly intercept larger particles, but the filtering effect on smaller particles is not good. When the slag slurry contains a large number of fine particles, the single-layer filter device may not be able to effectively intercept, causing blockage inside the pump body. In addition, the filtering area of the single-layer filter device is limited, and when a large amount of impurities accumulates on the filter layer, it is easy to cause the filter layer to be blocked. Once the filter layer is blocked, it needs to be stopped for cleaning, affecting the normal operation of the slag slurry pump.

[0004] More importantly, single-layer filter devices have poor adaptability to different types of slag slurry. When the composition and particle size of the slag slurry change, it may be necessary to replace the filter layer or adjust the parameters of the filter device, which increases the operation difficulty and cost.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0023] For example, Figure 1 - Figure 5The filter device for preventing slag slurry pump from being blocked is shown, which is composed of a pump body 1, a first interface 2, a second interface 3 and a transmission device 4. Its characteristics are that the slag slurry pump is effectively prevented from being blocked and the operation efficiency and safety of the equipment are improved through special filter design and sealing structure; the pump body 1 serves as the main body of the whole device, and the pump body 1 is responsible for pumping slag slurry; the first interface 2 and the second interface 3 are installed on the side wall of the pump body 1 and are used for connecting the anti-blocking filter device 5; the transmission device 4 is installed on the side wall of the pump body 1 and is connected with the impeller in the pump body 1, and is responsible for driving the pump body 1 to work; the anti-blocking filter device 5 includes a connecting pipeline and a flange. The connecting pipeline is provided with a flange at both ends, and the flange is connected with the first interface 2 or the second interface 3 through insertion bolts; a sealing ring is arranged at the connection position of the sealing structure flange and the first interface 2 or the second interface 3, so as to ensure that the connection position does not leak;

[0024] The first inclined insertion pipe 6, the second inclined insertion pipe 7 and the third inclined insertion pipe 8 are installed on the pipeline of the anti-blocking filter device 5 and are arranged in sequence from left to right; the inclined frame 9 is installed inside the inclined insertion pipe, and the double-layer filter screen 10 is installed inside the inclined frame 9; the mesh holes of the double-layer filter screen 10 are sequentially reduced from left to right, which can effectively filter impurities of different sizes; the connecting cover 11 is designed in an integrated manner with the inclined frame 9 and is fixed with the first inclined insertion pipe 6, the second inclined insertion pipe 7 and the third inclined insertion pipe 8 through bolts. A sealing ring is arranged at the connection position to ensure the sealing property; the first sealing element 12 and the second sealing element 13 include a T-shaped sealing strip and a square sealing ring. The T-shaped sealing strip is embedded in the upper and lower grooves of the inclined frame 9, and the square sealing ring is sleeved on the inclined frame 9, which together ensure the sealing property of the inclined frame 9. The filter device is designed through the unique inclined insertion pipe and the double-layer filter screen 10, which effectively prevents the slag slurry pump from being blocked and improves the operation efficiency and safety of the equipment. At the same time, through careful sealing structure design, the stability and reliability of the device in long-time operation are ensured.

[0025] Working process: when the slag slurry pump starts, the transmission device 4 starts to work, drives the impeller in the pump body 1 to rotate, thereby generating pumping effect. The pump body 1 starts to pump the slag slurry, and the slag slurry enters the anti-blocking filter device 5 from the first interface 2 or the second interface 3; the slag slurry entering the anti-blocking filter device 5 first passes through the first inclined pipe 6, and the inclined frame 9 and the double-layer filter screen 10 are installed here. The design of the double-layer filter screen 10 makes the mesh gradually decrease from left to right, so that different sizes of impurities can be filtered out. Larger impurities are intercepted by the first layer of filter screen, and smaller impurities pass through the first layer to the second layer and are intercepted again; the slag slurry filtered by the first layer continues to flow to the right and enters the second inclined pipe 7 and the third inclined pipe 8. The two inclined pipes are also provided with inclined frames 9 and double-layer filter screens 10, and the slag slurry is filtered again to ensure that the impurities in the slag slurry are completely removed; in the whole filtering process, in order to ensure that the slag slurry does not leak, sealing structures are designed at multiple connection positions. The connection position of the flange and the first interface 2 or the second interface 3 is provided with a sealing ring, and the connection cover 11 between the inclined frame 9 and the inclined pipe is also provided with a sealing ring, so as to ensure the sealing performance of the connection position. In addition, the T-shaped sealing strip and the square sealing ring of the first sealing element 12 and the second sealing element 13 together ensure the sealing performance of the inclined frame 9; the slag slurry filtered by the three layers of filter screens finally flows out from the output end of the anti-blocking filter device 5 and enters the next processing or conveying process.

[0026] The inclined pipe design of the utility model makes the slag slurry affected by gravity during the flowing process, and large-particle impurities are more likely to sink downward, thereby effectively improving the filtering efficiency; through the design of multiple layers of filter screens, the slag slurry can be filtered multiple times to ensure that the impurities in the slag slurry are completely removed. The design of the mesh gradually decreasing from left to right can filter out impurities of different sizes and improve the filtering precision; due to the special design of the inclined filter device, large-particle impurities are more likely to be intercepted and settled, thereby effectively preventing the slag slurry pump from being blocked and improving the operation efficiency and safety of the equipment; the design of the inclined filter device makes maintenance more convenient. When it is necessary to clean or replace the filter screen, only the corresponding inclined pipe needs to be disassembled, without the need to disassemble the whole device, so that the maintenance cost and time are greatly reduced; the inclined filter device is suitable for slag slurry pumps of different specifications and models, and only the number and size of the inclined pipes and the filter screens need to be adjusted according to specific requirements, so that the adaptability is very strong;

[0027] The above is the preferred embodiment of the utility model and the technical principle used thereby, and for those skilled in the art, any equivalent transformation, simple replacement and the like based on the technical scheme of the utility model without departing from the spirit and scope of the utility model shall belong to the protection range of the utility model.
