Description

Technical Field

[0001] This utility model relates to the field of mine backfilling technology, specifically to a slurry distributor for mine backfilling pipelines. Background Technology

[0002] In mine backfilling operations, the transportation and distribution of slurry are crucial steps, directly affecting backfilling efficiency and project quality. Traditional backfilling pipeline systems typically employ an independent one-in-one-out configuration, meaning each backfilling area requires a separate discharge pipeline. When dealing with multiple backfilling areas, operators must frequently disassemble the discharge equipment and switch to the target discharge pipeline to meet the backfilling needs of different areas.

[0003] However, this operating method has significant technical drawbacks. First, frequent disassembly and reinstallation of the equipment not only increases operational complexity but may also lead to a decline in the equipment's sealing performance, resulting in leakage problems. Second, after each disassembly, to ensure stability and sealing in subsequent use, the discharge equipment must be thoroughly cleaned, a process that is not only time-consuming and labor-intensive but also significantly reduces overall work efficiency. The traditional system's single feed and single discharge design cannot simultaneously meet the filling needs of multiple areas and multiple pipelines, limiting the flexibility and adaptability of filling operations. Therefore, developing a mine filling pipeline slurry distributor that can achieve multi-pipe material distribution, eliminates the need for frequent disassembly, and possesses highly efficient sealing performance has become an urgent technical challenge to be solved. Utility Model Content

[0004] This utility model proposes a slurry distributor for mine filling pipelines, which solves the technical problem of low working efficiency in the distribution of slurry in mine filling pipelines in the prior art.

[0005] The technical solution of this utility model is implemented as follows: A slurry distributor for mine filling pipelines is characterized by comprising a distribution bin and an inlet pipe provided on one side thereof, wherein the distribution bin is provided with multiple outlet pipes, which are distributed sequentially on the distribution bin.

[0006] Furthermore, the top of the material distribution bin is equipped with a detachable flange cover, which is connected to the material distribution bin by bolts and has a sealing gasket on the inside.

[0007] Furthermore, the inner bottom wall of the material distribution bin is provided with spiral patterns, which are distributed radially from the center outward along the bottom of the material distribution bin.

[0008] Furthermore, the inlet and outlet are designed in layers, with the inlet located at the upper part of the distribution bin and the outlet located at the lower part of the distribution bin.

[0009] Furthermore, the material distribution bin is equipped with a spiral blade to guide the slurry; the slurry is divided by the spiral blade, and forms a vortex from top to bottom with the spiral blade before being discharged from the discharge pipe.

[0010] The beneficial effects of the technical solution provided in this application are as follows: 1. This mine filling pipeline slurry distributor, by setting up a distribution bin structure with multiple outlet pipes, effectively solves the problems of low efficiency and poor sealing reliability caused by frequent disassembly and assembly of pipelines in traditional filling systems. This device can achieve a one-in-multiple-outlet slurry distribution mode, flexibly switching to different filling working faces without repeated pipeline disassembly, significantly reducing non-working time, improving filling efficiency, and simultaneously reducing the risk of leakage and labor maintenance costs caused by disassembly and assembly. 2. The slurry distributor in this mine filling pipeline features a layered design for its inlet and outlet. The inlet is located at the top of the distribution hopper, while the outlet is located at the bottom. The higher position of the inlet allows the slurry to flow naturally towards the outlet using gravity, thus reducing the need for additional power. The slurry is divided by spiral blades, and the combined action of the blades and spiral patterns creates a stable vortex from top to bottom before being discharged from the outlet.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example 1

[0016] This utility model provides a slurry distributor for mine filling pipelines, combined with... Figures 1 to 4 As shown, the structural design and operating principle of the distributor will be described in detail below. Specific embodiments and reference numerals further illustrate the technical solution of this utility model and its practical application effects.

[0017] like Figure 1 As shown, the slurry distributor for mine filling pipelines includes a distribution bin 10 and an inlet 20 located on one side of it. The distribution bin 10 is the core component of the entire device, with a cylindrical or rectangular shape, capable of accommodating and efficiently distributing the slurry input from the inlet 20. Multiple outlets 30 are located on different side walls of the distribution bin 10, distributed sequentially around its perimeter, and each outlet is connected to the interior of the bin. When the slurry enters the distribution bin from the inlet 20, it flows naturally to the various outlets under gravity, thus simultaneously delivering slurry to multiple filling areas. This multi-outlet design avoids the need for frequent disassembly and switching of discharge equipment in traditional methods, significantly reducing operational steps and improving work efficiency.

[0018] The top of the material distribution bin 10 is equipped with a detachable flange cover 40, such as Figure 2 As shown, the flange cover is bolted to the distribution bin, and an inner sealing gasket ensures a tight seal between the cover and the bin. When cleaning or maintenance of the distribution bin is required, the flange cover can be directly removed, allowing easy access to the bin for related operations. For example, after prolonged use, particles in the slurry may adhere to the bottom or inner wall of the bin; simply opening the flange cover allows for quick cleaning. Furthermore, the removable flange cover design facilitates inspection of wear on internal components and timely replacement of damaged parts, thereby extending the equipment's lifespan.

[0019] The inner bottom wall of the material distribution bin 10 is provided with spiral patterns 50, such as Figure 3As shown, the spiral pattern radiates outwards from the center along the bottom of the distribution bin, guiding the slurry flow and creating a vortex effect. After entering the distribution bin, the slurry rotates under the influence of the spiral pattern, ensuring even distribution and preventing localized accumulation or poor flow. For example, when the slurry contains large particles, the spiral design reduces the likelihood of these particles remaining in the distribution bin, thus improving slurry distribution efficiency. Furthermore, the spiral pattern reduces the residence time of the slurry within the distribution bin, further enhancing the smoothness of slurry distribution.

[0020] Example 2

[0021] The inlet 20 and outlet 30 employ a layered design, with the inlet located at the upper part of the distribution bin and the outlet at the lower part. The inlet's higher position allows the slurry to flow naturally towards the outlet using gravity, reducing the need for additional power. This layered design not only improves the efficiency of slurry distribution but also reduces energy consumption during operation. For example, in practical applications, after the slurry enters the distribution bin from the inlet, it slowly descends along the inner wall and flows to the various outlets under the combined action of the spiral grooves and gravity. This process eliminates the need for additional pumping equipment, reducing operating costs.

[0022] The material distribution bin 10 is also equipped with spiral blades 60 to guide the flow of slurry, such as... Figure 4 As shown, the spiral blades are fixed to the inner wall of the distribution bin, extending in a spiral shape from top to bottom along the height of the bin. The slurry is divided by the spiral blades, and under the combined action of the blades and the spiral pattern, a stable vortex is formed from top to bottom before being discharged from the outlet. For example, when the slurry contains a high concentration of solid particles, the spiral blade design enhances the slurry's fluidity and uniformity, effectively preventing slurry retention and blockage within the distribution bin. Furthermore, the spiral blades guide the slurry to form a more uniform flow path, ensuring that the slurry does not experience flow deviation or interruption during distribution.

[0023] The inner wall surface of the dispensing bin 10 is polished to reduce the frictional resistance between the slurry and the inner wall during flow. The surface roughness of the polished inner wall is controlled below Ra0.8μm, thereby reducing the possibility of slurry adhesion and further improving the slurry's fluidity. For example, under long-term continuous operation, fine particles in the slurry can easily adhere to the inner wall of the dispensing bin, causing slurry flow obstruction. The polished inner wall can significantly reduce this adhesion phenomenon and facilitate subsequent cleaning operations. In addition, the smooth surface treatment of the inner wall also reduces the time and labor costs required for cleaning and maintenance, improving the overall operating efficiency of the equipment.

[0024] Both the inlet 20 and outlet 30 are equipped with adjustable valves to control the flow rate and velocity of the slurry. The adjustable valves are controlled by manual or electric actuators to flexibly adjust the slurry distribution ratio according to the needs of different filling areas. For example, in practical applications, some filling areas may require a higher slurry flow rate, while other areas require a lower flow rate. Adjusting the valves allows for precise control of the flow rate at each outlet, ensuring the stability and accuracy of the slurry supply. Furthermore, the adjustable valve design prevents leakage caused by excessive slurry pressure, further improving the equipment's sealing performance.

[0025] The material distribution silo 10 is made of high-strength wear-resistant steel to withstand the wear caused by particles in the slurry on the inner wall of the silo. High-strength wear-resistant steel has excellent impact resistance and corrosion resistance, maintaining the structural strength and sealing performance of the silo during long-term use. For example, in mine backfilling operations, the slurry typically contains a large number of sand and gravel particles, which can cause severe wear to the inner wall of the silo during high-speed flow. The silo made of high-strength wear-resistant steel effectively resists this wear, extending the service life of the equipment. Furthermore, the outer wall of the silo is coated with an anti-corrosion coating to enhance the durability of the equipment in harsh environments. This anti-corrosion coating protects the silo from corrosion in humid or acidic / alkaline environments, further improving the reliability of the equipment.

[0026] In actual operation, the slurry is fed into the distribution bin 10 through the inlet pipe 20. After entering the distribution bin, the slurry begins to flow downwards under the action of gravity. Guided by the spiral 50 and spiral blades 60, the slurry forms a vortex and is evenly distributed inside the distribution bin. The slurry continues to flow along the inner wall of the distribution bin and finally reaches each outlet pipe 30. The flow rate of each outlet pipe is controlled by adjusting the adjustable valve to ensure that the slurry is distributed to different filling areas according to a predetermined ratio. Throughout the process, the structural design and functional configuration of the distribution bin work together to achieve efficient and stable slurry distribution.

[0027] In summary, this utility model provides more efficient and reliable technical support for mine backfilling operations through optimized structural design and functional configuration. Specifically, by setting multiple discharge ports, simultaneous material supply to multiple areas is achieved, avoiding the need for frequent disassembly and switching of discharge equipment; the design of the detachable flange cover simplifies the cleaning and maintenance of the equipment's interior; the combination of spiral patterns and spiral blades guides the slurry to form a vortex, ensuring uniform distribution and efficient discharge of the slurry within the distribution bin; the layered design of the inlet and outlet ports fully utilizes the gravity effect of the slurry, reducing additional power requirements; and the adjustable valve design enables precise control of slurry flow rate and velocity. The combination of these innovations significantly improves the efficiency of slurry distribution and extends the service life of the equipment, while reducing cleaning and maintenance costs and operational complexity.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
