[0002] In industries such as mines and building materials, the high-frequency vibrating screen, as an important screening device, is widely used in the classification of materials such as ores and gravels. However, during the screening process, due to the continuous impact and friction of the materials, a large amount of dust will be generated. These dusts will not only pollute the production environment, affect the health of operators, but also may cause potential safety hazards such as fires and explosions. Therefore, how to effectively control the dust pollution during the screening process has become a problem to be solved.

[0003] At present, there are already various solutions for controlling the dust of vibrating screens in the market, such as spray dust reduction and bag dust removal. However, these solutions still have some deficiencies in actual applications. Some dust reduction devices have unsatisfactory dust reduction effects due to unreasonable designs or limited technical levels, and cannot fully meet the dust reduction requirements of the production site. Some spray dust reduction devices lack precise control during the water spraying process, resulting in serious waste of water resources and increased production costs. Summary of the Utility Model

Detailed Embodiments

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 The dust reduction device for high-frequency vibrating screens provided by the present utility model mainly consists of four major parts: a screen frame 1, a spraying assembly, a water supply assembly, and a control system. The screen frame 1 serves as the main load-bearing structure for ore screening, and its design needs to meet the requirements of high-frequency vibration to ensure that the ore can be evenly and efficiently classified through the screen mesh.

[0023] The spraying assembly is the core part of the dust reduction device, and its design is directly related to the coverage range, uniformity, and dust reduction effect of the water mist. The specific design is as follows:

[0024] The pressure pump 2 serves as the power source of the entire spraying system, and its selection needs to be comprehensively considered based on factors such as the size of the screen frame 1, the required water mist pressure and flow rate, etc. In this embodiment, a high-pressure plunger pump is selected as the pressure pump 2. This pump has the advantages of stable output pressure, adjustable flow rate, wear resistance, etc., and can meet the dust reduction requirements of high-frequency vibrating screens. The pressure pump 2 is fixed on a stable bracket near the screen frame 1 by bolts to reduce the impact of vibration on its operating stability.

[0025] The connecting pipe 3 is made of high-strength and corrosion-resistant stainless steel tubing. Its diameter is determined according to the water output flow rate of the pressure pump 2 to ensure unobstructed water flow. One end of the connecting pipe 3 is tightly connected to the water outlet end of the pressure pump 2, and the other end is connected to the water pipe 4 through a flange or quick connector. The water pipe 4 is also made of stainless steel, and its design needs to consider sufficient rigidity and flexibility to adapt to the spatial layout around the screen frame 1. The water pipe 4 is laid parallel to the screen frame 1 to ensure that the water mist can cover the screening area.

[0026] Please refer to Figure 2 As shown in, the annular water mist generator 5 is a key component of the spraying assembly, and its design directly determines the generation effect of the water mist. In this embodiment, the annular water mist generator 5 adopts a rectangular structure, and its width is adapted to the width of the screen frame 1 to ensure that the water mist can be sprayed closely along the edge of the screen frame, preventing the dust generated during screening from drifting outside. A plurality of spray nozzles 51 are evenly distributed at the bottom of the annular water mist generator 5. The number, spacing, and spraying angle of the spray nozzles 51 are carefully calculated to ensure that the water mist can evenly and densely cover the entire screening area. The spray nozzles 51 are made of stainless steel and are equipped with an anti-blocking design to improve service life and reliability.

[0027] The water supply assembly is responsible for providing a stable and sufficient water source for the spraying assembly, and its design needs to consider issues such as water source access, water volume monitoring, and replenishment.

[0028] The water tank 6, as the main container for storing water source, its capacity needs to be determined according to the duration of the screening operation and the water consumption. In this embodiment, the water tank 6 is made of stainless steel, which has the advantages of corrosion resistance and easy cleaning. A viewing plate 61 is fixed on the side of the water tank 6. The viewing plate 61 is made of a transparent material (such as tempered glass or transparent plastic) and is marked with water level scale lines, so that the operator can observe the remaining water volume inside the water tank at any time and replenish the water source in time. The water tank 6 is fixed on a stable ground near the screen frame 1 through a bracket to reduce the influence of vibration on its stability.

[0029] The water inlet pipe 7, as the pipeline connecting the water tank 6 and the external water source, its design needs to consider factors such as the access method of the water source, water pressure and flow rate. In this embodiment, the water inlet pipe 7 is made of corrosion-resistant PVC pipe. One end of it is connected to the water inlet end of the water tank 6, and the other end is connected to the external water source (such as tap water, well water, etc.) through accessories such as valves and filters. Monitoring devices such as a flow meter and a pressure gauge are also provided on the water inlet pipe 7 to monitor and adjust the water inlet flow rate and water pressure in real time.

[0030] The control system, as the "brain" of the entire dust suppression device, is responsible for receiving sensor signals, executing control instructions and adjusting the working state of the spraying components. In this embodiment, the control system uses a PLC (Programmable Logic Controller) as the core control unit, which has the advantages of flexible programming, high reliability and easy maintenance.

[0031] The dust concentration sensor 8 is used to monitor the dust concentration in the screening area in real time and transmit the monitoring data to the control system. In this embodiment, the dust concentration sensor 8 is arranged inside the screen frame 1, near the dust generation areas such as the ore feeding point. The dust concentration sensor 8 uses a high-precision and high-sensitivity photoelectric or laser sensor, which can accurately measure the dust particle concentration in the air and convert the measurement result into an electrical signal and output it to the control system.

[0032] The control system automatically adjusts the working state of the spraying components according to the data transmitted by the dust concentration sensor 8 through the preset control logic. When the dust concentration exceeds the set threshold, the control system starts the pressure pump 2, and the annular water mist generator 5 starts to spray water mist for dust suppression; when the dust concentration drops below the set threshold, the spraying is automatically stopped, realizing intelligent and automatic dust suppression control. In addition, the control system also has a manual control function, allowing the operator to manually adjust according to the actual situation to meet the dust suppression requirements under different working conditions.

[0033] Optimization Measures and Effect Evaluation

[0034] In order to ensure that the dust suppression device achieves the best effect in practical applications, some optimization measures can be taken and the implementation effect can be comprehensively evaluated.

[0035] Through multiple experiments and adjustments, the layout and spraying angle of the spray nozzle 51 are further optimized. Ensure that each spray nozzle can spray water mist onto the screening area at the best angle to form a continuous and uniform water mist curtain, effectively suppressing dust diffusion. At the same time, according to changes in parameters such as ore types and screening speeds, the spraying flow rate and pressure of the spray nozzle can be flexibly adjusted to adapt to different screening conditions. When the dust concentration is relatively low, the spraying frequency and water volume can be appropriately reduced; when the dust concentration rises sharply, the spraying intensity and range are rapidly increased to ensure effective dust control.

[0036] Regular maintenance and upkeep of the dust suppression device are the key to ensuring its long-term stable operation. Develop detailed maintenance plans and maintenance procedures, including regularly checking whether the spray nozzles are blocked, cleaning the water tank and pipelines, and replacing worn parts.

[0037] Conduct a comprehensive evaluation of the implementation effect of the dust suppression device. By monitoring indicators such as the change in dust concentration, water resource consumption, and equipment operation stability in the screening area, evaluate the dust suppression effect, economy, and reliability of the dust suppression device. At the same time, collect the feedback opinions and suggestions of the operators, and continuously improve and optimize the device. The evaluation results show that the dust suppression device has achieved remarkable results in reducing dust pollution and improving the production environment, while realizing water resource conservation and stable operation of the equipment.

[0038] In summary, through measures such as precise control of water mist spraying, optimization of the spray nozzle layout and spraying angle, and strengthening of maintenance and upkeep, this embodiment effectively controls the dust generated during the ore screening process. This device has the advantages of good dust suppression effect, high water resource utilization rate, simple and reliable operation, etc., and has broad application prospects in industries such as mines and building materials.

[0039] 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 replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
