Description

Technical Field

[0001] This invention relates to the field of stone processing technology, specifically to a dust reduction device for stone polishing equipment. Background Technology

[0002] In stone processing, polishing is a core step, generating a large amount of fine stone dust. This dust, typically less than 5μm in diameter, contains free silica and is highly diffusive. It not only severely pollutes the production environment but also poses a significant threat to the health of operators, potentially leading to serious occupational diseases such as pneumoconiosis with prolonged exposure. Furthermore, dust accumulation can disrupt the normal operation of polishing equipment, reduce production efficiency, and increase equipment maintenance costs.

[0003] Existing dust suppression measures are mostly open-type water spraying or ventilation-type dust suppression, but the effects are often unsatisfactory. Open-type water spraying is difficult to effectively capture all dust and will cause water accumulation in the work area; ventilation-type dust suppression only uses fans to expel dust, which cannot effectively treat the dust and will still cause secondary pollution to the environment, and the dust collection rate is only 60-70%, resulting in poor dust suppression effect.

[0004] Therefore, how to provide a dust suppression device with good dust suppression effect and effective dust collection and treatment is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dust suppression device for stone grinding equipment, aiming to solve the problems of poor dust suppression effect and secondary environmental pollution caused by existing dust suppression devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A dust suppression device for stone grinding equipment includes a support mechanism, a dust suppression mechanism rotatably mounted on the support mechanism, and telescopic rods symmetrically mounted between the support mechanism and the dust suppression mechanism on both sides.

[0008] Furthermore, the support mechanism serves as the installation foundation for the entire device, supporting the stone grinding equipment and dust suppression mechanism. It includes a support base, a support platform on the top surface of the support base, power supply modules symmetrically arranged on both sides of the support platform, and lower support columns symmetrically fixed on both sides of the support base. The support platform is used to support and install the stone grinding equipment. The power supply module has a parallel circuit structure, an external waterproof power line, and is suitable for the humid environment of stone processing, providing a continuous and stable power supply.

[0009] Furthermore, the support mechanism also includes liquid receiving trays symmetrically installed on both sides of the support base, a waste liquid tank opened in the support base, and a cleaning tank connected to the lower rear side of the support base; the liquid receiving trays are used to receive dusty wastewater; a waste liquid tank is also movably installed in the waste liquid tank to collect the wastewater after preliminary filtration, which is convenient for subsequent recycling and reuse.

[0010] Furthermore, an extension slot is connected between the liquid receiving tray and the waste liquid tank. The outer end of the extension slot is flush with the bottom surface of the liquid receiving tray, and the inner end extends above the waste liquid tank, which can ensure that the sewage in the liquid receiving tray flows completely into the waste liquid tank and avoid side leakage.

[0011] Furthermore, the dust suppression mechanism is rotatably mounted on the support mechanism to cover the grinding area and achieve dust adsorption and wastewater collection. Specifically, it includes a dust suppression hood rotatably mounted on the top of the support base, air intake components symmetrically arranged on both sides of the lower end of the dust suppression hood, air outlets symmetrically arranged on both sides of the upper end of the dust suppression hood, and upper support columns symmetrically fixed on the outer walls of both sides of the dust suppression hood. The rotation axis of the dust suppression hood is located directly behind the support platform. The dust suppression hood also covers the periphery of the support platform. The upper support columns are close to the rotation axis of the dust suppression hood. The air intake components are used to continuously introduce air into the grinding area and push the dust-laden gas out from the air outlets.

[0012] Furthermore, the lower end of the telescopic rod is a telescopic base, which is rotatably mounted on the lower support column via a hinge; the upper end of the telescopic rod is a telescopic end, which is rotatably mounted on the upper support column via a hinge. By utilizing the telescopic action of the telescopic rod, the dust suppression mechanism can be driven to rotate around its rotation axis between unfolding and closing.

[0013] Furthermore, the dust suppression mechanism also includes a liquid collection assembly symmetrically installed on the outer wall of the dust suppression hood and an atomizer symmetrically installed on the top of the dust suppression hood; the atomizer is located above the air outlet and adopts a dual-fluid atomization structure, which can atomize water to form a water mist wall, efficiently adsorbing dust; the liquid collection assembly is located below the air outlet and is used to collect dust-laden wastewater and guide it into the liquid receiving tray.

[0014] Furthermore, the air intake assembly includes air intake chambers symmetrically arranged on the outer wall of the dust cover and multiple air intake pipes equidistantly installed on the inner wall of the dust cover; the outer end of the air intake pipe is connected to the air intake chamber and is inclined at 30° to facilitate the uniform diffusion of airflow to the grinding area.

[0015] Furthermore, the air intake assembly also includes multiple air intake fans equidistantly installed on the outer wall of the air intake chamber and multiple on / off wires corresponding to the air intake fans installed at the bottom of the air intake chamber; the air intake fans face the outside of the air intake pipe and are axial flow fans, which can drive outside air into the air intake chamber; the on / off wires are electrically connected to the air intake fans; a stainless steel filter screen is also provided on the outside of the air intake fans to filter impurities in the air and prevent impurities from entering the grinding area and affecting the processing quality; the lower end of the on / off wires also abuts against the power supply module to transmit electrical energy and realize the automatic start and stop of the air intake fans.

[0016] Furthermore, the liquid collection assembly includes a liquid collection channel connected below the air outlet, a filter chamber connected at the lower end of the liquid collection channel, and a drain channel connected at the lower end of the outer side of the filter chamber; the lower outlet of the drain channel corresponds to the upper part of the liquid receiving tray and is used to guide sewage into the liquid receiving tray; the upper cross section of the liquid collection channel is an inverted V-shaped structure with the opening gradually decreasing downwards, so as to facilitate the collection of liquefied sewage.

[0017] Furthermore, the filter chamber is symmetrically provided with filter slots, and filter components are movably secured between the filter slots. Movable locking posts are also movably installed in the filter chamber and abut against the outer end of the filter components. A spring is provided at the bottom of the movable locking post, which can automatically extend and retract to abut against the filter components to prevent them from slipping during use.

[0018] Furthermore, the filter assembly includes a filter frame, side clips symmetrically arranged on both sides of the filter frame, and a filter screen installed between the filter frames; the filter screen is made of stainless steel mesh with a 100-mesh aperture, which can effectively filter dust particles in wastewater; the side clips are movably locked in the filter slots; the length of the filter assembly is less than the height of the support base, ensuring that it can be smoothly removed from the filter chamber when in a vertical position.

[0019] Compared with the prior art, the present invention provides a dust suppression device for stone grinding equipment, which has the following beneficial effects:

[0020] 1. This application forms a relatively closed processing chamber by setting a rotatable dust hood and a support platform, which effectively prevents dust from overflowing and avoids secondary pollution to the environment; at the same time, combined with the air intake component to inject air into the chamber, the dust-laden gas is pushed through the water mist wall formed by the atomizer to achieve efficient dust adsorption, with a dust reduction rate of over 90%, which significantly improves the working environment.

[0021] 2. This application controls the opening and closing of the dust cover by setting a telescopic rod, and realizes the linkage between the air intake fan and the dust cover status by using the contact and separation of the on / off rod and the power supply module; the air intake fan is automatically started when the dust cover is closed and automatically cut off when it is opened. The operation is simple and does not require additional manual operation, thus reducing the labor intensity of the operators.

[0022] 3. In the device of this application, the wastewater generated by dust suppression is automatically collected into the receiving tray through the collection channel, the filtration chamber and the discharge channel, and finally flows into the waste liquid tank to realize the collection of wastewater; the detachable filter components in the filtration chamber can effectively intercept particulate matter in the wastewater, which facilitates the subsequent treatment and recycling of wastewater.

[0023] 4. The filter component in this application device is installed in a slot and locked by a movable locking post; when the dust removal mechanism is flipped to the unfolded state, the filter component is located just above the cleaning tank, and the staff can easily unlock it and let it slide into the cleaning tank for cleaning, which greatly facilitates daily maintenance and upkeep.

[0035] Please see Figures 1-9 This invention provides a technical solution for a dust suppression device for stone grinding equipment:

[0036] Example 1

[0037] A dust suppression device for stone polishing equipment includes a support mechanism 1, a dust suppression mechanism 2 rotatably mounted on the support mechanism 1, and telescopic rods 3 symmetrically mounted between the support mechanism 1 and the dust suppression mechanism 2.

[0038] The support mechanism 1 serves as the installation foundation for the entire device, supporting the stone grinding equipment and the dust suppression mechanism 2. It includes a support base 11, a support platform 12 on the top surface of the support base 11, power supply modules 13 symmetrically arranged on both sides of the support platform 12, and lower support columns 17 symmetrically fixed on both sides of the support base 11. The support platform 12 supports the installation of the stone grinding equipment. The power supply modules 13 have a parallel circuit structure with an external waterproof power line, adaptable to the humid environment of stone processing, and can continuously and stably provide power. The support mechanism 1 also includes liquid receiving trays 14 symmetrically installed on both sides of the support base 11, a waste liquid tank 16 opened within the support base 11, and a cleaning tank 15 connected to the lower rear side of the support base 11. The liquid receiving trays 14 collect dusty wastewater. The waste liquid tank 16 also has a movable waste liquid container 5 for collecting pre-filtered wastewater for subsequent recycling. An extension slot 18 is connected between the liquid receiving tray 14 and the waste liquid tank 16. The outer end of the extension slot 18 is flush with the bottom surface of the liquid receiving tray 14, and the inner end extends above the waste liquid tank 16, which can ensure that the sewage in the liquid receiving tray 14 flows completely into the waste liquid tank 5 and avoid side leakage.

[0039] The dust suppression mechanism 2 is rotatably mounted on the support mechanism 1 and is used to cover the grinding area and realize dust adsorption and wastewater collection. Specifically, it includes a dust suppression hood 21 rotatably mounted on the top of the support base 11, an air inlet assembly 24 symmetrically arranged on both sides of the lower end of the dust suppression hood 21, an air outlet 25 symmetrically arranged on both sides of the upper end of the dust suppression hood 21, and upper support columns 27 symmetrically fixed on the outer walls of both sides of the dust suppression hood 21. The rotation axis of the dust suppression hood 21 is located directly behind the support platform 12. The dust suppression hood 21 also covers the periphery of the support platform 12. The upper support columns 27 are close to the rotation axis of the dust suppression hood 21. The air inlet assembly 24 is used to continuously introduce air into the grinding area and push the dust-laden gas out from the air outlet 25.

[0040] The lower end of the telescopic rod 3 is a telescopic base, which is rotatably mounted on the lower support column 17 via a hinge; the upper end of the telescopic rod 3 is a telescopic end, which is rotatably mounted on the upper support column 27 via a hinge. By utilizing the telescopic action of the telescopic rod 3, the dust suppression mechanism 2 can be driven to rotate around its rotation axis between unfolding and closing.

[0041] The dust collection mechanism 2 also includes a liquid collection assembly 22 symmetrically installed on the outer wall of the dust collection hood 21 and an atomizer 23 symmetrically installed on the top of the dust collection hood 21. The atomizer 23 is located above the air outlet 25 and is also provided with a water inlet. The atomizer 23 adopts a dual-fluid atomization structure with a droplet SMD≤80μm and atomization uniformity of ±5%. It can atomize water to form a water mist wall and efficiently adsorb dust. The liquid collection assembly 22 is located below the air outlet 25 and is used to collect dust-containing wastewater and guide it into the liquid receiving tray 14.

[0042] The air intake assembly 24 includes an air intake chamber 242 symmetrically arranged on the outer wall of the dust cover 21 and a plurality of air intake pipes 241 equidistantly installed on the inner wall of the dust cover 21; the outer end of the air intake pipe 241 is connected to the air intake chamber 242 and is inclined at 30° to facilitate the uniform diffusion of airflow to the polishing area. The air intake assembly 24 also includes multiple air intake fans 243 equidistantly installed on the outer wall of the air intake chamber 242 and multiple on / off wires 244 corresponding to the air intake fans 243 installed at the bottom of the air intake chamber 242. The air intake fans 243 face the outside of the air intake pipe 241, are axial flow fans with a power of 50W, and can drive outside air into the air intake chamber 242. The upper end of the on / off wire 244 is electrically connected to the air intake fan 243. A stainless steel filter screen is also provided on the outside of the air intake fan 243 to filter impurities in the air and prevent impurities from entering the grinding area and affecting the processing quality. The lower end of the on / off wire 244 also abuts against the power supply module 13 to transmit electrical energy and realize the automatic start and stop of the air intake fan 243.

[0043] The liquid collection assembly 22 includes a liquid collection channel 221 connected below the air outlet 25, a filter chamber 222 connected to the lower end of the liquid collection channel 221, and a drain channel 223 connected to the lower outer end of the filter chamber 222. The lower outlet of the drain channel 223 corresponds to the upper part of the liquid receiving tray 14 and is used to guide sewage into the liquid receiving tray 14. The upper cross section of the liquid collection channel 221 is an inverted V-shaped structure that gradually decreases in size downwards to facilitate the collection of liquefied sewage. The filter chamber 222 is also symmetrically provided with filter slots 2221, and a filter assembly 4 is movably secured between the filter slots 2221. A movable locking post 26 is also movably installed in the filter chamber 222, abutting against the outer end of the filter assembly 4. A spring is provided at the bottom of the movable locking post 26, which can automatically extend and retract to abut against the filter assembly 4 to prevent it from slipping during use.

[0044] The filter assembly 4 includes a filter frame 41, side locking blocks 43 symmetrically arranged on both sides of the filter frame 41, and a filter screen 42 installed between the filter frames 41. The filter screen 42 is made of stainless steel mesh with a 100-mesh aperture, which can effectively filter dust particles in sewage. The side locking blocks 43 are movably locked in the filter slot 2221. The length of the filter assembly 4 is less than the height of the support base 11, ensuring that it can be smoothly removed from the filter chamber 222 when in a vertical position.

[0045] Example 2

[0046] In practical use, the automated stone grinding equipment is installed inside the support platform 12. After installation is completed and grinding work begins, the atomizer 23 and the power supply module 13 are powered on by an external power source. The power supply module 13 uses waterproof wiring, which can effectively avoid short circuits caused by humid environments. Then, the water inlet at the top of the atomizer 23 is connected to a faucet through a retractable hose, which is available in the prior art. Then, the telescopic rod 3 is controlled to retract to drive the dust suppression mechanism 2 to rotate around the rotating shaft until the dust suppression hood 21 completely covers the outside of the support platform 12. At this time, the lower end of the drain channel 223 is located above the liquid receiving tray 14, which can ensure that the sewage flows smoothly into the liquid receiving tray 14.

[0047] While the dust cover 21 is covering the support platform 12, the on / off wire rod 244 is in complete contact with the power supply module 13. The power supply module 13 provides power to the intake fan 243 through the on / off wire rod 244 to drive its rotation. Then, the filter assembly 4 is correspondingly locked between the filter slots 2221 by the side locking block 43. The movable locking post 26 automatically extends under the action of the bottom spring and abuts against the outer end of the filter assembly 4 to prevent it from slipping out during use. Finally, turn on the water tap and start the atomizer 23 to remove dust. The atomizer 23 atomizes the injected water and sprays it out, forming a uniform water mist wall between the air outlets 25, which can efficiently adsorb dust.

[0048] During the stone polishing process, a large amount of dust is generated and fills the processing cavity between the support platform 12 and the dust cover 21. During this period, the intake fan 243 rotates at high speed, filtering impurities in the air through the external filter screen, and then drawing external air into the intake chamber 242. The continuously flowing air is evenly output to the processing cavity inside the dust cover 21 through the intake pipe 241. The incoming air pushes the polluted gas mixed with dust in the processing cavity outward from the air outlets 25 on both sides of the dust cover 21. As the polluted gas is output outward, it passes under the atomizer 23. The continuously output water mist comes into contact with and adsorbs the dust in the polluted gas. The clean gas after adsorption can then be output to the environment from the outside of the air outlet 25. The atomizer 23 effectively adsorbs the dust in the gas by forming water mist, avoiding the direct emission of dust gas into the air and causing secondary pollution to the environment, while also preventing the dust from being inhaled by the operators.

[0049] The water mist adsorbing dust gathers into droplets and sinks downwards under gravity. The inverted V-shaped structure at the upper end of the collection channel 221 accelerates the gathering of droplets, allowing them to flow into the collection channel 221. This forms a wastewater flow that flows downwards through the collection channel 221 and into the filter chamber 222 through its lower end. As the wastewater flows downwards through the filter chamber 222, the particulate matter in the wastewater is filtered onto the filter screen 42 by the filter assembly 4. The coarsely filtered water continues to flow downwards and into the drain channel 223 through the lower end of the filter chamber 222. Finally, it flows out through the lower end of the drain channel 223 into the receiving tray 14. The wastewater flowing into the receiving tray 14 flows into the waste liquid tank 5 through the extension slot 18. The design of the extension slot 18, with its outer end flush with the bottom surface of the receiving tray 14 and its inner end extending above the waste liquid tank 16, ensures that the wastewater flows completely into the waste liquid tank 5, preventing side leakage and enabling the collection, treatment, and reuse of wastewater, thus reducing water waste.

[0050] After the first stage of polishing is completed, turn off the external water tap and the atomizer 23. Then, extend the telescopic rod 3 to drive the dust collection mechanism 2 to rotate around its axis. During rotation, the on / off rod 244 separates from the power supply module 13, disconnecting the power supply to the intake fan 243 and stopping its operation. The telescopic rod 3 stops operating when the filter assembly 4 rotates from a horizontal to a vertical position, at which point the filter assembly 4 is directly above the cleaning tank 15. At this point, the operator can press the movable locking pin 26 inward to compress the bottom spring, causing the movable locking pin 26 to disengage from the filter assembly 4. Then, the operator can hold the filter assembly 4 by hand, and the filter assembly 4 will move downward along the filter slot 2221 under gravity and fall directly into the cleaning tank 15. Finally, the removed filter assembly 4 can be placed in the cleaning tank 15 for rinsing to remove impurities from the filter screen 42 for future use. It should be noted that the length of the filter assembly 4 is less than the height of the support base 11 to ensure that the filter assembly 4 can be easily removed from the filter chamber 222 when in a vertical position. After cleaning, the telescopic rod 3 is retracted, which drives the dust suppression mechanism 2 to close and the filter assembly 4 is re-secured in the filter slot 2221 by the side locking block 43. The movable locking post 26 automatically extends and contacts to fix it, and the next stage of grinding and dust suppression can be carried out. After the sewage in the waste liquid tank 5 is collected to a certain amount, the waste liquid tank 5 can be taken out and the sewage can be further treated and reused to reduce the cost of sewage treatment.

[0051] In addition, the atomizer 23, power supply module 13, and telescopic rod 3 used in the device of this application are all implemented by existing technology. The principle of the contact and energization between the on / off rod 244 and the telescopic rod 3 is the same as the principle of electrical appliances being plugged in and energized in the prior art. The specific working principle will not be described in detail in this technical solution.

[0052] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
