[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this utility model is to provide a slurry pipeline outlet slag-blocking device to solve the problems of subsequent equipment blockage and wear caused by debris at the outlet of the slurry pipeline, as well as reduced production efficiency and shortened equipment life caused by debris in the existing technology. It has a simple structure, high reliability, facilitates online slag removal, reduces downtime, and can effectively protect the slurry pipeline outlet slag-blocking device of the subsequent mineral processing equipment.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a slag-blocking device for the outlet of a slurry pipeline, such as... Figures 1-5As shown, the device includes: a grate filter cylinder 4, an anti-impact component 5, and a hanging mechanism. The grate filter cylinder 4 has filter gaps on its wall for the slurry to pass through and for intercepting impurities. The bottom of the grate filter cylinder 4 has a filter layer. The anti-impact component 5 is located on the inner bottom side of the grate filter cylinder 4 and below the slurry flow channel. The anti-impact component 5 includes a buffer member for withstanding the impact of the slurry and a support member for supporting the buffer member on the bottom of the grate filter cylinder 4. The hanging mechanism is used to detachably suspend and fix the grate filter cylinder 4 below the outlet of the slurry pipe 1. By setting these main components, the grate filter cylinder 4, the anti-impact component 5, and the hanging mechanism, a complete slag-separating device is constructed. The filtration gap and bottom filter layer of the grate filter cylinder 4 can effectively achieve the initial separation of slurry and impurities. The anti-impact component 5 can protect the bottom of the grate filter cylinder 4 from damage caused by slurry impact. The hanging mechanism facilitates the installation and disassembly of the device, and makes subsequent maintenance and cleaning easier. Overall, it improves the reliability and practicality of the device at the outlet of the slurry pipeline 1.

[0028] In a preferred embodiment, the suspension mechanism includes: a first lifting lug 101 fixed to the outlet end of the slurry pipe 1; a lifting ring 2 connected to the first lifting lug 101; and a lifting rod 3, the upper end of which is connected to the lifting ring 2 and the lower end of which is connected to the connecting part set on the top of the grate filter cylinder 4. This clear and simple suspension mechanism design clarifies the connection relationship between the various components, so that the grate filter cylinder 4 can be stably suspended below the outlet of the slurry pipe 1, ensuring the stability of the device installation, and thus ensuring that the slag-stripping device will not affect the slag-stripping effect due to shaking or displacement during operation.

[0029] In a preferred embodiment, an adjustable-length connector is provided between the lifting ring 2 and the first lifting lug 101, which gives the device greater flexibility. Depending on the actual installation of different slurry pipes 1 and the position of the grate filter cylinder 4 that may need to be adjusted, the operator can precisely adjust the height of the grate filter cylinder 4 through the connector to better adapt it to the slurry flow rate, flow rate and other parameters, thereby improving the slag removal efficiency.

[0030] In a preferred embodiment, the grate filter cylinder 4 is cylindrical. The cylinder wall of the grate filter cylinder 4 includes multiple vertically spaced bars arranged circumferentially. The filtration gap is the distance between the vertical bars. The cylindrical design helps to evenly distribute the force of the slurry on the cylinder wall, improving structural stability. The vertical bars and corresponding filtration gaps allow for more precise interception of impurities. By adjusting the gap size according to different impurity sizes, targeted filtration of impurities of specific sizes in the slurry can be achieved. Furthermore, this structure is simple, easy to manufacture, and easy to maintain.

[0031] In a preferred embodiment, at least one reinforcing ring is fitted and fixed on the outer side of the grate filter cylinder 4. The reinforcing ring includes an upper ring 402, a middle ring 403, and a lower ring 404. A second lifting lug 401 is fixedly connected to the outer periphery of the upper ring 402. The reinforcing ring can significantly enhance the overall structural strength of the grate filter cylinder 4. Especially under long-term impact from slurry and friction from impurities, it can effectively prevent deformation or damage to the cylinder wall, extend the service life of the grate filter cylinder 4, and ensure the stable operation of the entire slag-separating device.

[0032] In a preferred embodiment, the buffer component is a disc-shaped wear-resistant plate 501, which is horizontally suspended above the bottom filter layer of the grate filter cylinder 4. This horizontal suspension effectively buffers the direct impact of large debris in the slurry on the bottom filter layer of the grate filter cylinder 4. Because the wear-resistant plate 501 has excellent impact resistance, it can absorb and disperse most of the impact energy, thereby protecting the bottom filter layer from easy damage and maintaining its filtration effect.

[0033] In a preferred embodiment, the support component includes multiple support rods 502 and a support ring 502. The upper ends of the multiple support rods 502 are connected to the outer periphery of the wear-resistant plate 501, and the lower ends are connected to the support ring 502. The support ring 502 is fixedly supported on the bottom filter layer of the grate filter cylinder 4. This structure of the support component can provide stable support for the wear-resistant plate 501, ensuring that the wear-resistant plate 501 will not shift or shake during the impact of slurry and collision with debris. The multiple support rods 502 and the support ring 502 work together to make the supporting force evenly distributed, further enhancing the stability of the entire impact-resistant component 5 and ensuring that it can function effectively for a long time.

[0034] In a preferred embodiment, the wear-resistant plate 501 is made of impact-resistant high-strength composite material or alloy steel. The impact-resistant high-strength composite material or alloy steel wear-resistant plate 501 has excellent impact resistance and wear resistance. When faced with the high-speed impact of slurry and the continuous friction of impurities, it can maintain its structural integrity and performance stability for a long time, reducing the frequency of replacement due to wear or damage, lowering maintenance costs, and continuously ensuring impact protection.

[0035] In a preferred embodiment, the filtration gap of the grate filter cylinder 4 is set according to the target size of the impurities to be separated. Setting the filtration gap according to the target size of the impurities to be separated makes the slag-separating device highly targeted. It can accurately intercept impurities of the target size, avoiding subsequent equipment from being blocked or worn by harmful impurities of specific sizes. This meets the diverse needs of slurry impurity filtration and equipment protection in different mineral processing operations, and improves the versatility and adaptability of the device.

[0036] The following is a method of using the slag-blocking device at the outlet of a slurry pipeline provided by this utility model.

[0037] Before using the slurry pipeline outlet slag-blocking device, the filtration gap of the grate filter cylinder 4 must be pre-set according to the target size of the impurities to be separated in the mineral processing operation to ensure that it can effectively intercept impurities of the corresponding size. During installation, the grate filter cylinder 4 is first detachably suspended and fixed below the outlet of the slurry pipeline 1 using a hanging mechanism. The adjustable length connector between the lifting ring 2 and the first lifting lug 101 is adjusted to place the grate filter cylinder 4 at a suitable height to ensure that the slurry can flow smoothly into the cylinder. After the slurry flows out of the pipeline outlet, it first impacts the buffer component, i.e., the wear-resistant plate 501, located on the bottom side of the inside of the grate filter cylinder 4. The wear-resistant plate 501 disperses and buffers the impact force of the slurry, preventing direct impact on the bottom filter layer. Subsequently, the slurry flows inside the grate filter cylinder 4, and the impurities it carries are intercepted by the filtration gaps of the cylinder wall and the bottom filter layer. The slurry that meets the requirements is discharged through the filtration gaps and filter layer. When the amount of debris trapped inside the grate filter cylinder 4 reaches a certain level, the grate filter cylinder 4 can be removed by disassembling the hanging mechanism to clean the internal debris. After cleaning, it can be reinstalled for continued use. Throughout the entire usage process, the impact-resistant material used in the wear-resistant plate 501 can withstand the impact of slurry for a long time, while the supporting components stably support the wear-resistant plate 501. The reinforcing ring further ensures the structural strength of the grate filter cylinder 4. The coordinated action of all components achieves efficient slag separation and protects subsequent mineral processing equipment.
