Description

Technical Field

[0001] This utility model relates to the field of floating waste rock cleaning technology, and more specifically, to a pressurized cleaning device for floating waste rock. Background Technology

[0002] Belt conveyors are core equipment for material transportation in industries such as mining, coal, metallurgy, and building materials, undertaking the task of continuously transporting materials such as coal, ore, and gangue. During material transportation, it is inevitable that small particles of loose rock (waste rock, impurities) will adhere to or accumulate on the surface of the belt, rollers, idlers, etc., mainly causing the following problems: Affecting transportation efficiency: Loose rock accumulation can cause belt misalignment, slippage, and even blockage of the discharge port, resulting in downtime for maintenance and affecting the continuity of production.

[0003] In existing technologies, high-velocity air is typically used to blow dust along the belt running direction within the feed chute channel to remove dust. For example, patent CN217708056U discloses a multi-functional dust removal device for belt conveyors. Specifically, it uses high-speed induced air to blow dust along the belt running direction within the feed chute channel, achieving non-powered dust removal through expansion, pressure relief, circulation, and attenuation steps. However, it is only suitable for lightweight dust and cannot be applied to impurities with a certain weight, such as loose rocks (e.g., waste rock, impurities).

[0004] Based on the above description, there is an urgent need for a pressurized cleaning device that can both remove dust and loose debris. Utility Model Content

Detailed Implementation

[0022] The specific implementation method is described below with reference to the accompanying drawings.

[0023] Example 1

[0024] Please see Figures 1 to 4 The present invention provides the following technical solution: a pressure cleaning device for floating gangue, which is suitable for cleaning particulate impurities such as floating gangue and dust.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, a pressurized cleaning device for floating gangue includes a high-pressure water pump 1, a water supply pipe 2, multiple nozzles 3, and multiple pressurizing components 4; the high-pressure water pump 1 is located at the water inlet end of the water supply pipe 2; the multiple pressurizing components 4 are spaced apart on the water supply pipe 2; the multiple nozzles 3 are spaced apart along the axial direction of the water supply pipe 2 between a pair of pressurizing components 4; the nozzles 3 are connected to the water supply pipe 2.

[0026] In this embodiment, the high-pressure water pump 1 serves as the power source, establishing an initial high-pressure water flow channel through the water supply pipe 2. Furthermore, by distributing multiple pressurizing components 4 at intervals along the water supply pipe 2, segmented pressurization nodes are formed, thereby achieving a gradual increase in water pressure and ensuring that each nozzle 3 continuously sprays water at high pressure for efficient cleaning of floating debris and dust. In particular, by placing the nozzle 3 between adjacent pressurizing components 4, the stable high-pressure water flow after two stages of pressurization can be directly utilized to generate impact force through directional spraying, further achieving the stripping and pushing of floating debris.

[0027] In this embodiment, to achieve automatic cleaning of floating debris, an electric gate 7 is further installed at the inlet end of the water supply pipe 2, and multiple dust sensors and a PLC controller are electrically connected to achieve automatic cleaning. Specifically, the dust sensors adopt commonly used electrostatic induction dust sensors and light scattering dust sensors, which can realize regional dust sensing. Then, the electrical signal is transmitted to the PLC controller, such as the Schneider Modicon TSX series, and the opening degree of the electric gate 7 is controlled by the output digital signal of the PLC controller.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the water supply pipe 2 includes multiple interconnected transmission pipe sections 21; the pressurization assembly 4 is located between two adjacent transmission pipe sections 21.

[0029] In this embodiment, the water supply pipe 2 is connected by multiple transmission pipe sections 21. Each transmission pipe section 21 serves as an independent water flow transmission unit, which not only reduces the pressure loss along the long-distance pipeline but also facilitates replacement and maintenance, as well as flexible adjustment of the cleaning path length. The pressurization component 4 is located between adjacent transmission pipe sections 21, forming an alternating operation mode of transmission and pressurization. That is, the previous transmission pipe section 21 smoothly delivers the water flow to the pressurization component 4. After pressurization, the next transmission pipe section 21 guides the high-pressure water flow to the nozzle 3. This not only reduces water flow disturbance by shortening the length of a single pipe section but also facilitates flexible adjustment of the number of transmission pipe sections and the position of the pressurization component 4 for different cleaning areas, adapting to the layout requirements under complex working conditions.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the pressurization assembly 4 includes a contraction section 41, a pressurization section 42, and a diffusion section 43; a pair of transmission pipe sections 21 are respectively connected to the contraction section 41 and the diffusion section 43; the contraction section 41 and the diffusion section 43 are connected through the pressurization section 42.

[0031] In this embodiment, the contraction section 41 gradually contracts to increase the water flow velocity, thereby achieving efficient conversion of static pressure energy into kinetic energy according to Bernoulli's principle, and storing energy for subsequent pressurization. The pressurization section 42, as a kinetic energy enhancement zone, reduces energy loss by stabilizing the high-speed flow field, ensuring efficient transfer of kinetic energy to the diffusion section. Furthermore, the diffusion section 43 gradually expands its cross-section to decelerate the high-speed water flow, converting kinetic energy back into static pressure energy, and achieving a secondary increase in water pressure. Thus, through the synergistic effect of this three-section structure, the outlet pressure of a single pressurization component 4 can be effectively increased compared to the inlet pressure, solving the problem of insufficient pressurization by a single-stage water pump, as well as the situation where insufficient water pressure in the later section of the pipe due to an excessively long cleaning path, and insufficient spray force of the nozzle 3, resulting in the inability to thoroughly clean the floating debris.

[0032] Specifically, such as Figure 4 As shown, the pressurization section 42 is provided with multiple axially extending guide strips 5; the multiple guide strips 5 are arranged around the inner wall of the pressurization section 42. The guide strips 5 gradually contract towards the center of the pressurization section 42.

[0033] In this embodiment, the multiple guide strips 5 on the inner wall of the pressurization section 42 are evenly distributed in a ring. Their core function is to suppress the turbulence effect of high-speed water flow. When water flows into the pressurization section 42 at high speed, it is easy to generate eddy current loss due to boundary layer separation. The guide strips 5 can divide the water flow into multiple independent streams. Furthermore, by setting the guide strips 5 to a structure that contracts towards the center, the streams are further guided to converge towards the center. The centrifugal force generated by the spiral flow is used to entrain the low-energy fluid in the boundary layer into the mainstream, replenishing the energy of the core area. This achieves the purpose of rectification. That is, the turbulence intensity in the pressurization section 42 can be reduced through rectification, thereby improving the uniformity of the flow velocity distribution, significantly reducing kinetic energy loss, and ensuring that more energy is used for pressure recovery in the subsequent diffusion section 43.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, both ends of the transmission pipe section 21 are provided with a first flange 211; the contraction section 41 is provided with a second flange 411 that matches the first flange 211; and the diffusion section 43 is provided with a third flange 431 that matches the first flange 211. The end of the second flange 411 away from the pressure boosting section 42 and the end of the third flange 431 away from the pressure boosting section 42 are both provided with a sealing groove for the sealing ring to be embedded.

[0035] In this embodiment, the first flange 211 of the transmission pipe section 21 is rigidly connected to the second flange 411 and the third flange 431 of the pressurizing assembly 4 by bolts, forming a stable mechanical seal structure. The flanges increase the sealing contact area, and together with the nitrile rubber O-rings in the sealing groove, an initial seal is achieved. When the pressure inside the pipeline increases, the water pressure acts on the inner side of the O-ring, pushing the sealing ring to expand outward of the sealing groove, making the sealing surface fit more tightly and forming a self-tightening sealing effect. The higher the pressure, the more reliable the sealing effect. The even distribution of multiple sets of M16 high-strength bolts can further ensure the force balance of the flange surface, avoid leakage problems caused by local deformation, and adapt to high-pressure conditions.

[0036] Specifically, such as Figure 3 As shown, the third flange 431 is provided with a microporous plate 6.

[0037] In this embodiment, the microporous plate 6 inside the third flange 431 has a dual function. Its dense pores can intercept mud and sand particles carried in the water flow, preventing hard impurities from entering the subsequent pipeline and wearing down the nozzle or causing blockage, thus extending the service life of the equipment. At the same time, the microporous plate 6 forms a moderate local resistance to the water flow, which can attenuate the pressure fluctuation at the outlet of the diffuser section, keeping the pressure fluctuation amplitude within a certain pressure range. This ensures that the water flow pressure entering the next transmission pipe section 2 is stable, providing continuous and uniform spraying power to the nozzle 3 and avoiding the problem of unstable cleaning effect caused by pressure fluctuation.
