Description

Technical Field

[0001] The utility model relates to the technical field of ore stirring, in particular to a pressure relief and dustproof component and a high-speed flexible stirring barrel of a filling station. Background Art

[0002] A high-speed flexible mixer is a machine that mixes large pieces of material into powder. In the prior art, in order to prevent the leakage of dust generated during mixing, the mixer adopts a relatively sealed structure. A plate-shaped hinged sealing cover is set on the top of the mixing barrel. Although the sealing cover can block most of the powder, there is still a gap when the sealing cover is closed, and dust will escape from the gap, which not only affects the on-site working environment, but also causes the dissipation of materials and the pressure in the mixing barrel to rise.

[0003] In summary, existing high-speed flexible stirring has at least the following risks:

[0004] 1. Risk of pressure accumulation: When a high-speed flexible mixer is operating, if the gas in the barrel cannot be discharged, the pressure will continue to rise, posing a safety hazard.

[0005] 2. Occupational health threats: Failure to effectively release the pressure in the barrel may result in insufficient mixing of cement and tailings delivered by the spiral metering scale, causing dust leakage, increasing dust pollution in the workshop, and endangering the health of workers.

[0006] 3. Reduced stirring efficiency: The gas film formed by gas accumulation will affect the uniformity and efficiency of stirring, reducing the stirring effect.

[0007] 4. Increased operational difficulty: The lack of an effective pressure relief device makes it difficult for the equipment to regulate the pressure in the barrel (which will rise sharply). Additional measures need to be taken to prevent excessive pressure, which increases the complexity of operation.

[0008] 5. Increased maintenance costs: Long-term high-pressure operation may cause unstable equipment operation, increasing the difficulty and cost of maintenance. Utility Model Content

[0035] Example 1

[0036] like Figures 1 to 3 As shown, the utility model provides a technical solution:

[0037] A pressure relief and dustproof component, which at least includes but is not limited to a supporting structure 1, a cloth cover structure 2 and a fixed structure 3; the supporting structure 1 is connected to the fixed structure 3, the cloth cover structure 2 is sleeved on the supporting structure 1, and the cloth cover structure 2 is fixed to the supporting structure 1 by a restraining member 4.

[0038] Based on the above structure, the supporting structure 1 provides support for the cloth cover structure 2 to prevent the cloth cover structure 2 from collapsing, so that the cloth cover structure 2 can always be dust-proof in the state of maximum surface. The restraining part 4 can fix the cloth cover structure 2 to prevent the cloth cover structure 2 from falling off. The cloth cover structure 2 can also be quickly disassembled through the restraining part 4, and the cloth cover structure 2 can be cleaned in time to ensure dust removal efficiency.

[0039] As an example, the support structure 1 can be a cylindrical structure with openings at both ends of the support structure 1, the bottom of the support structure 1 is connected to the structure to be dustproof, and the side wall of the support structure 1 is provided with air holes; the air holes are evenly distributed on the side wall of the support structure 1.

[0040] Based on the above structure, the support structure 1 not only provides support for the cloth cover structure 2, but the air holes on the side wall also provide space for dust to move, so that the entire dust can diffuse to the cloth cover structure 2 more efficiently and evenly.

[0041] As an example, a matching groove 5 may be provided inside the fixing portion, a support block 6 may be provided at the bottom of the support structure 1, the support ring can be snapped into the matching groove 5 for fixation, and a snap-in groove 7 having a size matching that of the support block 6 may be provided in the fixing portion;

[0042] At least two support blocks 6 are provided along the bottom of the support structure 1 .

[0043] Based on the above structure, the support is inserted into the matching groove 5 through the snap-in groove 7. By rotating the support structure 1, the support block 6 is inserted into the matching groove 5 to complete the fixation of the support structure 1. In this way, the support structure 1 can be disassembled and installed very quickly, reducing the difficulty of subsequent maintenance.

[0044] As an example, at least two restraining members 4 are provided along the length direction of the matching cloth cover structure 2, and the two restraining members 4 are respectively provided at the upper and lower ends of the cloth cover structure 2 to fix the two ends of the cloth cover structure 2 to prevent dust from escaping from the connection.

[0045] As an example, a connection belt 8 that matches the size of the restraining member 4 may be provided on the cloth cover structure 2 , and the setting position of the connection belt 8 matches the restraining member 4 .

[0046] Based on the above structure, when in use, the restraint 4 can be passed through the connecting belt 8 to connect the restraint 4 and the connecting belt 8 into one, forming a stable connection structure, avoiding the cloth cover structure 2 from falling off due to accidents, and further ensuring the stability of the cloth cover structure 2 when connected.

[0047] As an example, a limiting groove 9 for use with the restraining member 4 may be provided along the length direction of the supporting structure 1 , and the size of the limiting groove 9 matches that of the restraining member 4 .

[0048] Based on the above structure, the limiting groove 9 can also prevent the restraining member 4 from falling off the supporting structure 1, while also ensuring the accuracy of the restraining member 4 during installation, thereby improving the installation efficiency of the entire assembly.

[0049] As an example, the cloth cover structure 2 has an accuracy of 1 to 200 μm and a temperature resistance of 94° C. It is mainly used for dust removal and adsorption and has high strength, wear resistance, acid and alkali corrosion resistance, and good elastic recovery rate.

[0050] Example 2

[0053] Based on the above structure, the frequency conversion motor 12 rotates to drive the stirring assembly 13 to rotate, thereby crushing large pieces of material. Since the pressure relief and dust prevention assembly is provided in this solution, a large pressure will not be formed in the stirring barrel 10. The pressure relief and dust prevention assembly can effectively discharge the gas generated during the stirring process, preventing the equipment from malfunctioning or causing safety accidents due to pressure overload. At the same time, the pressure relief and dust prevention assembly can also effectively control gas emissions, reduce the risk of liquid and dust escaping, and ensure the safety of operators and the environment.

[0054] At the same time, by setting up a pressure relief and dust prevention component, the foam generation during the stirring process can be reduced, further improving the stirring effect. It can also make pressure control and equipment maintenance simpler and reduce equipment failure rate.

[0055] The cloth cover structure 2 in this solution is simple, has low maintenance costs, does not require external energy drive, and achieves green operation. It can effectively filter dust, prevent the leakage of harmful substances (silicon dioxide), reduce environmental pollution and occupational health, and has significant environmental protection effects.

[0056] As an example, the support structure 1 has a height of 1 m and a diameter of 150 mm.

[0057] As an example, the stirring assembly 13 may include a rigid stirring blade 14 , a chain stirring blade 15 and a spoiler 16 ; the rigid stirring blade 14 and the chain stirring blade 15 are arranged on the rotating shaft, and the spoiler 16 is arranged on the chain stirring blade 15 .

[0058] Based on the above structure, this high-speed flexible mixer operates at a speed range of 100 to 500 rad / min. Its rapidly rotating chain-type mixing blades 15, working in tandem with the rigid mixing blades 14, efficiently and thoroughly disperse the filling material, ensuring uniform mixing and effectively stimulating cement activity, thereby significantly enhancing the strength of the filling. Furthermore, the mixer is equipped with a variable-frequency motor 12, which adjusts the mixing speed according to the different characteristics of the filling material, achieving a low-energy, high-quality filling slurry preparation process.

[0059] The steps for using and disassembling the cloth cover structure 2 are as follows:

[0060] Installation Procedure: After ensuring that the mixing drum 10 and other equipment are completely shut down, drill a hole (150 mm) above the mixing drum 10 and install a 1-meter-high, 150-mm-diameter bag air cap bracket. Check that the bag bracket is vertical, skewed, or deformed, and confirm that the bag cap is not damaged. Operate carefully to ensure that the bag cap is flat and firmly installed on the bracket to prevent leakage and mechanical damage.

[0061] Disassembly steps: After completely shutting down the machine and cutting off the power supply, loosen the fixing screws in the fixed order, carefully remove the bag cap to prevent dust leakage, and clean and inspect after disassembly.

[0062] Cleaning steps: remove impurities and dust, deal with stubborn stains, soak and clean, clean thoroughly, rinse until there is no foam, dry naturally, inspect and repair, and finally reinstall the bag cap.
