Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to an environmentally friendly wall polishing device that prevents dust. Background Art

[0002] With the rapid development of the construction industry, wall grinding, as an important step in wall construction and decoration, has a direct impact on the subsequent decoration effect and overall aesthetics. Traditional wall grinding methods mainly rely on manual operation, using handheld sandpaper or simple electric grinding tools. This is not only inefficient, but also produces a lot of dust during the grinding process. This dust not only harms the health of construction workers, but also pollutes the construction environment and affects the quality of life of surrounding residents.

[0003] In order to solve the above problems, some grinding devices with dust suction functions have appeared on the market, aiming to improve grinding efficiency while reducing dust emission. However, the existing grinding devices still have some shortcomings in practical applications and cannot fully meet the construction site's requirements for high efficiency and environmental protection.

[0004] Chinese invention patent CN118288137B discloses a high-efficiency wall grinding device for decorative engineering. The device includes a machine head, a connecting seat and a grinding mechanism. The motor drives the rotating shaft to rotate, driving the grinding disc and sandpaper to grind the wall surface. The gear transmission drives the dust suction impeller to rotate, generating negative pressure to absorb dust generated by grinding, reducing air pollution. At the same time, a structure is designed that can synchronously grind the inner corners of the wall, eliminating dead corners and improving grinding efficiency.

[0005] However, the device mainly relies on mechanical transmission, has a complex structure, and has many components, which makes it prone to mechanical failure and increases maintenance costs. The negative pressure suction method of the dust suction impeller is less efficient in high-dust environments and cannot completely prevent the escape of dust, posing a threat to the health of construction workers. In addition, the device has limited adaptability to the flatness of the wall and cannot be intelligently adjusted according to the unevenness of the wall, which affects the quality of polishing.

[0006] Chinese invention patent CN117817464B discloses a building wall smoothing and polishing device. The device uses a detachable first cover plate and a second cover plate to change the opening range of the box body to adapt to different polishing areas, realize closed polishing of the wall range, and reduce dust leakage. This design can ensure the polishing of double-sided corners and multiple walls without being affected by the edge of the polishing equipment shell or the dead angle of rotating polishing.

[0007] However, the closed design of the device may have problems with loose sealing in actual operation, and dust may still escape from the gaps. It is mainly used for grinding corners and multiple walls, and the efficiency improvement for grinding large-area walls is limited. The device is large in size, not flexible in operation, and cannot be intelligently adjusted according to the flatness of the wall, which affects the grinding effect. Utility Model Content

The compensation adjustment block, the grinding drive block and the adjustment block are all piezoelectric stacks made of piezoelectric materials.

[0010] The piezoelectric stack made of piezoelectric material is used as a driving and adjusting element, which reduces the use of mechanical transmission components and reduces the failure rate and maintenance cost of the device. The suction hood forms a closed space around the grinding disc and the fixed disc. Combined with the design of the through hole and the suction hole, the air flow is guided to achieve efficient dust collection and prevent dust from escaping. The adjustment block of the device can adjust the distance between the grinding disc and the wall surface in real time according to the flatness of the wall to ensure the uniformity and quality of the grinding. The design of the air collection ring, dust collection pipe and dust collection bucket achieves efficient collection and filtration of dust, protects the health of construction workers, and meets environmental protection requirements. The utility model is suitable for occasions such as building decoration and wall finishing that require wall grinding, and is particularly suitable for indoor decoration projects with strict requirements on dust pollution control. The design of this device can effectively reduce hidden costs in the construction process, such as dust control and personnel health risks. At the same time, efficient construction and good grinding quality can improve the overall quality of the decoration project, meet customers' demand for high-quality decoration, and have good market prospects and economic benefits.

[0011] The distance between the inner wall of the air suction hood and the outer end of the fixed plate is one to two millimeters, the distance between the grinding plate and the fixed plate is one to two millimeters, the air inlet pipe runs through the air suction hood, and the through part is rotatably connected to the air suction hood.

[0012] One end of the air intake pipe 1 away from the grinding disc is fixedly connected to a ball head, the end of the ball head away from the air intake pipe 1 is fixedly connected to the air intake pipe 2, and the end of the air intake pipe 2 away from the ball head is connected to the external air supply system.

[0013] An air collecting ring is fixedly connected to one end of the air suction hood away from the grinding disc.

[0015] The second air inlet pipe is made of stainless steel, the dust collecting pipe is a flexible hose, and the outer ends of the second air inlet pipe and the dust collecting pipe are jointly clamped with a plurality of adjustment clamps.

[0016] An outer end of one of the adjustment cards is fixedly connected to an adjustment bracket, which is used to support the adjustment card. A rotating mechanism is provided at one end of the adjustment bracket close to the adjustment card.

[0017] One end of the adjusting link away from the adjusting bracket is rotatably connected with a ball, and the end of the ball away from the adjusting link is arranged in contact with the wall to be polished.

[0018] The end surfaces of the grinding disc, the fixing disc and the suction hood away from the ball head are in the same plane.

[0019] The beneficial effects of the utility model are:

[0020] 1. Highly efficient dust prevention: an air suction hood is set around the grinding disc and the fixed disc to form an enclosed space for collecting dust generated during the grinding process. Multiple through holes on the grinding disc allow gas and dust to pass through, and the dust is quickly sucked into the dust removal chamber in conjunction with the air suction holes. The dust and gas mixture in the dust removal chamber is guided to the gas collecting ring and then enters the dust collecting bucket through the dust collecting pipe. The dust collecting bucket is equipped with a filter layer to effectively filter dust. Clean gas enters the external suction system through the exhaust end to prevent secondary pollution of dust. The entire dust collection system is reasonably designed, which effectively prevents the escape of dust, improves the construction environment, and protects the health of operators.

[0021] 2. Environmentally friendly and efficient grinding. The device uses a piezoelectric stack made of piezoelectric material as the grinding drive block and adjustment block. Through electrical signal control, it realizes tiny and precise mechanical vibration and displacement. The micro-rotation mode driven by the piezoelectric stack makes the grinding disc swing back and forth at a small angle to perform fine grinding on the wall surface. This method has low energy consumption, no mechanical noise, and meets environmental protection requirements. At the same time, the piezoelectric material has a fast response speed and high precision, which improves the efficiency and quality of grinding and ensures the flatness and smoothness of the wall surface.

[0022] 3. Strong adaptability and flexible adjustment. The adjustment block is used to adjust the distance between the grinding disc and the wall surface to adapt to the flatness of different wall surfaces. The adjustment block between the connecting rod and the outer wall of the suction hood can adjust the distance between the suction hood and the wall to optimize the dust collection effect. The ball design ensures that the suction hood can slide smoothly during the adjustment process without damaging the wall surface. In addition, the application of the adjustment bracket and adjustment card enables the operator to easily adjust the height and angle of the device to adapt to the construction of walls at different heights and angles, thereby enhancing the adaptability and flexibility of the device.

[0023] 4. Easy to operate and reduces labor intensity. By adjusting the bracket and adjustment card, the operator can easily adjust the position and angle of the device without frequent movement, which reduces labor intensity. The setting of the rotating mechanism increases the flexibility of adjustment, so that the device can easily cope with complex construction environments. The dust collection bucket can be slid to adjust the position. As the dust accumulates, the force balance of the device can be adjusted, which facilitates users to better operate the equipment and improves work efficiency.

[0024] 5. The structure is stable, reliable and durable. The air inlet pipe is made of stainless steel with good corrosion resistance and strength, ensuring the stability and safety of gas transportation. The dust collection pipe adopts a flexible hose to facilitate the adjustment of the position of the dust collection bucket, maintain the balance of the device, and adapt to different working environments. The various components of the device adopt a modular design with a reasonable connection method. The overall structure is stable and durable, which extends the service life of the equipment.

[0025] 6. Excellent grinding effect. The end faces of the grinding disc, fixed disc and suction hood away from the ball head are in the same plane, ensuring good contact between the device and the wall surface. The micro-rotation grinding method makes the grinding process smooth, reduces damage to the wall, and avoids scratches or unevenness that may be caused by traditional grinding methods. The adjustment block fine-tunes the position and angle of the grinding disc according to the flatness of the wall, ensuring the uniformity and high quality of the grinding effect.

[0026] 7. The dust is filtered thoroughly and maintained easily. The filter layer in the dust collecting bucket can effectively filter the dust and prevent the dust from being discharged with the air flow and causing secondary pollution. The design of the dust collecting bucket is convenient for disassembly and cleaning, and the sliding connection makes it more convenient to maintain. The entire dust collection and filtering system ensures the cleanliness of the construction environment and meets environmental protection requirements.

[0027] 8. Energy saving and environmental protection, in line with modern needs, using piezoelectric materials as driving elements, low energy consumption, no mechanical wear, no noise pollution during operation, in line with the modern concept of energy conservation and environmental protection, the design of the device fully considers the effective use of energy and environmental protection, and has good social benefits.

[0040] Example 1

[0041] like Figures 1 to 9 As shown, this embodiment provides an environmentally friendly wall grinding device for preventing dust, including a grinding disc 1, a plurality of through holes 2 are opened on the grinding disc 1, a fixed disc 3 is fixedly connected to the outer end of the grinding disc 1, a compensation adjustment block 4 is fixedly connected between the grinding disc 1 and the fixed disc 3, an air intake pipe 5 is fixedly connected to the center of one end of the fixed disc 3 away from the grinding disc 1, the air intake pipe 5 passes through the fixed disc 3, and a plurality of key teeth are provided at the outer end of the passing part, and the outer ends of the plurality of key teeth are clamped with the same connecting rod 6.

[0042] Both ends of the connecting rod 6 away from the air inlet pipe 5 are rotatably connected to the grinding drive block 7, and the end of the fixed disk 3 away from the grinding disk 1 is provided with an air suction hood 8. The ends of the two grinding drive blocks 7 away from the connecting rod 6 are rotatably connected to the air suction hood 8. A dust removal chamber 9 is provided in the air suction hood 8. A plurality of air suction holes 10 are provided in the dust removal chamber 9 near the outer wall of the fixed disk 3. The plurality of air suction holes 10 are all connected to the dust removal chamber 9. The outer end of the air suction hood 8 is fixedly connected to a plurality of adjustment brackets 11, and the adjustment bracket 11 is rotatably connected to the adjustment connecting rod 12. An adjustment block 13 is fixedly connected between the adjustment connecting rod 12 and the outer wall of the air suction hood 8.

[0043] The compensation adjustment block 4, the grinding drive block 7 and the adjustment block 13 are all piezoelectric stacks made of piezoelectric materials. The air suction hood 8 is arranged around the grinding disc 1 and the fixed disc 3 to form an enclosed space for collecting dust generated during the grinding process. The inner wall of the air suction hood 8 is one to two millimeters away from the outer end of the fixed disc 3, and the grinding disc 1 and the fixed disc 3 are two millimeters apart. The air inlet pipe 5 passes through the air suction hood 8, and the passing part is rotatably connected to the air suction hood 8.

[0044] A section of the air inlet pipe 5 away from the grinding disc 1 is fixedly connected to a ball head 14, a section of the ball head 14 away from the air inlet pipe 15 is fixedly connected to the air inlet pipe 2 15, a section of the air inlet pipe 2 15 away from the ball head 14 is connected to the external air supply system, and the air hood 8 is fixedly connected to an air collecting ring 16 at one end away from the grinding disc 1, and the air collecting ring 16 is rotatably connected to the outer wall of the air inlet pipe 5. The air collecting ring 16 is a hollow structure, and the hollow part is connected to the dust removal chamber 9.

[0045] Working process

[0046] When in use, place the grinding disc 1, the fixed disc 3 and the end of the air hood 8 away from the ball head 14 close to the wall surface to be ground, ensuring that the grinding disc 1 is in full contact with the wall surface. By adjusting the bracket 11 and the adjusting connecting rod 12, the angle and position of the air hood 8 are adjusted to make the device adapt to walls of different heights and angles.

[0047] Starting the device, the grinding drive block 7 made of the piezoelectric stack generates tiny mechanical vibrations under the action of the electrical signal, pushing the connecting rod 6 to rotate back and forth. The connecting rod 6 drives the air intake pipe 5 and the grinding disc 1 to swing back and forth at a small angle to achieve fine grinding of the wall surface. The compensation adjustment block 4 fine-tunes the position and angle of the grinding disc 1 according to the flatness of the wall to ensure a uniform and smooth grinding effect.

[0048] During the grinding process, the external air supply system delivers gas with a certain pressure to the through hole 2 on the grinding disc 1 through the air inlet pipe 2 15, the ball head 14 and the air inlet pipe 1 5. The gas is ejected through the through hole 2 to form an airflow, passing through the gap between the grinding disc 1 and the wall, carrying the dust generated by grinding. These dust-containing gases are surrounded by the enclosed space formed by the suction hood 8, and enter the dust removal chamber 9 through the suction hole 10. The airflow in the dust removal chamber 9 gathers the dust into the hollow structure of the air collecting ring 16. The air collecting ring 16 is connected to the external dust removal system, and the dust is further processed or collected.

[0049] The adjusting block 13 adjusts the position of the adjusting link 12 through the piezoelectric effect, changes the distance and angle between the suction hood 8 and the wall, and ensures airtightness and effective collection of dust.

[0050] The enclosed space formed by the suction hood 8 around the grinding disc 1 and the fixed disc 3 can effectively prevent the dust generated during the grinding process from escaping. The dust generated by the grinding is carried by the air flow and quickly sucked in through the suction hole 10 and the dust removal chamber 9, avoiding pollution to the environment and protecting the health of the operator.

[0051] The grinding drive block 7 and the compensation adjustment block 4 made of a piezoelectric stack can achieve micro-grinding without mechanical noise, reduce energy consumption, and meet environmental protection requirements. At the same time, the piezoelectric material has the characteristics of fast response speed and high precision, which improves the efficiency and quality of grinding.

[0052] The compensation adjustment block 4 and the adjustment block 13 can fine-tune the position and angle of the grinding disc 1 and the suction hood 8 according to the flatness and grinding requirements of the wall to adapt to different wall conditions. Whether it is an uneven wall or a wall with a special angle, high-quality grinding operations can be performed.

[0053] By adjusting the bracket 11 and the adjusting rod 12, the operator can easily adjust the position and angle of the device to adapt to the construction of walls of different heights and angles. The overall structure of the device is compact, light, and easy to carry and operate.

[0054] The hollow structure of the air collecting ring 16 is connected to the dust removal chamber 9, and cooperates with the external dust removal system to achieve efficient collection and treatment of dust, avoiding the problem of dust flying everywhere in the traditional grinding method and improving the construction environment.

[0055] The air inlet pipe 1 5 is rotatably connected to the air suction hood 8, and the air inlet pipe 1 5 is connected to the air inlet pipe 2 15 through the ball head 14, so that the device has a certain flexibility during operation. Even in a complex wall environment, the device can be flexibly adjusted to maintain a stable polishing effect.

[0056] The device adopts a modular design, and each component is easy to disassemble and replace, which is convenient for maintenance and upkeep. The durability of the piezoelectric material reduces the frequency of replacement and lowers the cost of use.

[0057] The design of the device allows grinding, dust collection and wall adaptability adjustment to be carried out simultaneously, which simplifies the construction process, shortens the construction time and improves the overall construction efficiency.

[0058] To sum up, the dust-proof wall environmentally friendly grinding device of this embodiment realizes efficient, environmentally friendly and convenient wall grinding operations through reasonable structural design and advanced material application. The device not only improves the grinding quality and efficiency, but also effectively prevents the impact of dust on the environment and health. It has significant practical value and promotion prospects.

[0059] Example 2

[0060] like Figures 1 to 9 As shown, based on Example 1, an improved anti-dust wall environmentally friendly grinding device is further provided. This embodiment optimizes the dust removal and adjustment structure of the device, thereby enhancing the dust collection efficiency and adaptability of the device.

[0061] The device includes an air collecting ring 16, the bottom end of which is fixedly connected to a dust collecting pipe 17, and the end of the dust collecting pipe 17 away from the air collecting ring 16 is slidably connected to a dust collecting bucket 18. A filter layer is provided in the dust collecting bucket 18 for filtering dust generated during the grinding process. The exhaust end of the dust collecting bucket 18 is connected to an external suction system to ensure that the dust is effectively collected and processed.

[0062] The air intake pipe 15 is made of stainless steel, has good strength and corrosion resistance, and ensures the stability of the air supply. The dust collecting pipe 17 is a flexible hose with good bendability, which facilitates the adjustment of the device in different working environments. The outer ends of the air intake pipe 15 and the dust collecting pipe 17 are jointly connected with multiple adjustment cards 19, which are used to fix and adjust the positions of the air intake pipe 15 and the dust collecting pipe 17.

[0063] The outer end of one of the adjustment cards 19 is fixedly connected to an adjustment bracket 20, which is used to support the adjustment card 19 and maintain the stability of the device. The adjustment bracket 20 is provided with a rotating mechanism at one end close to the adjustment card 19 to facilitate adjusting the angle and height of the device to meet the needs of different construction environments.

[0064] The end of the adjusting link 12 away from the adjusting bracket 11 is rotatably connected to a ball, and the end of the ball away from the adjusting link 12 is arranged in contact with the wall to be polished. The design of the ball enables the device to maintain good contact with the wall surface during movement, reducing friction resistance and improving operational flexibility.

[0065] In addition, the end faces of the grinding disc 1, the fixed disc 3 and the suction hood 8 away from the ball head 14 are in the same plane. This design ensures that the device fits tightly with the wall surface during the grinding process, ensuring the uniformity of the grinding effect.

[0066] Working process

[0067] When using the device of this embodiment, first fit the grinding disc 1, the fixed disc 3 and the end of the suction hood 8 away from the ball head 14 to the wall surface to be ground. By adjusting the bracket 20 and the adjustment card 19, adjust the position and angle of the air inlet pipe 15 and the dust collection pipe 17 to make the device adapt to walls of different heights and positions. The rotating mechanism of the adjustment bracket 20 can flexibly adjust the angle of the device to meet various construction needs.

[0068] After starting the device, the grinding drive block 7 made of the piezoelectric stack generates tiny mechanical vibrations, pushing the connecting rod 6 to rotate back and forth, driving the air intake pipe 5 and the grinding disc 1 to perform micro-grinding. The compensation adjustment block 4 fine-tunes the position of the grinding disc 1 according to the flatness of the wall to ensure uniformity of grinding.

[0069] During the grinding process, the external air supply system transports the gas to the through hole 2 of the grinding disc 1 through the stainless steel air inlet pipe 2 15, the ball head 14 and the air inlet pipe 1 5. The gas is ejected through the through hole 2, carrying the dust generated by the grinding. The dust-containing gas is surrounded by the suction hood 8, enters the dust removal chamber 9 through the suction hole 10, and then enters the dust collecting pipe 17 through the air collecting ring 16.

[0070] Since the dust collecting pipe 17 is a flexible hose, its length and curvature can be adjusted as needed to facilitate the transportation of dust. The dust-containing gas enters the dust collecting barrel 18, passes through the internal filter layer, and the dust is intercepted. The purified gas enters the external suction system through the exhaust end for further processing or discharge.

[0071] The end of the adjusting link 12 away from the adjusting bracket 11 contacts the wall surface through the ball bearing. The design of the ball bearing enables the device to slide smoothly during movement, reducing friction and damage to the wall surface. At the same time, the presence of the ball bearing enables the adjusting link 12 to flexibly adjust the position of the air hood 8 to ensure the effective formation of a confined space.

[0072] By adding a dust collecting pipe 17 and a dust collecting bucket 18 at the bottom of the air collecting ring 16, the dust generated during the grinding process is collected more effectively. The setting of the filter layer ensures the effective separation of dust and gas, prevents dust from escaping into the environment, and improves environmental protection performance.

[0073] The dust collecting pipe 17 is made of a flexible hose and the air inlet pipe 15 is made of stainless steel, which not only ensures the stability of air supply and dust removal, but also improves the adaptability of the device in different construction environments. The setting of the adjustment card 19 and the adjustment bracket 20 allows the height and angle of the device to be flexibly adjusted to meet the needs of different wall surfaces and constructors.

[0074] The design of the rotating mechanism of the adjustment bracket 20 and the adjustment card 19 makes the adjustment of the device more convenient. The supporting effect of the bracket enhances the stability of the device, reduces shaking during operation, and ensures the grinding quality.

[0075] The ball bearing design at the end of the adjusting connecting rod 12 reduces the friction resistance when the device moves on the wall surface, making the operation more labor-saving. At the same time, the contact between the ball bearing and the wall surface ensures the fit between the device and the wall, thereby improving the efficiency and quality of the grinding.

[0076] The end faces of the grinding disc 1, the fixed disc 3 and the suction hood 8 away from the ball head 14 are in the same plane, ensuring a close fit between the device and the wall surface. This design makes the grinding more uniform and avoids uneven grinding caused by tilting or unevenness of the device.

[0077] The sliding connection design of the dust collecting bucket 18 makes it more convenient to clean and replace the filter layer. The operator can clean the dust collecting bucket 18 in time according to the accumulation of dust to ensure the normal operation of the device.

[0078] The various components of the device are connected by an adjustment mechanism and can be adjusted according to different construction environments and wall conditions. Whether it is high, low, flat or curved, the device can adapt flexibly to meet various grinding needs.

[0079] The use of high-quality materials such as stainless steel and flexible hoses ensures the durability and safety of the device. The application of piezoelectric stacks reduces mechanical transmission components, reduces the failure rate, and improves the reliability of the device.

[0080] Through multiple dust collection and filtering measures, the pollution of dust to the environment during the grinding process is minimized. The purified gas is processed through an external suction system and meets environmental emission standards.

[0081] To sum up, based on Example 1, this embodiment optimizes the design of the dust removal system and adjustment mechanism of the device. By adding components such as the dust collecting pipe 17, the dust collecting bucket 18, the adjustment card 19 and the adjustment bracket 20, the dust collection efficiency and operational convenience of the device are improved. The ball design reduces the operating resistance and enhances the adaptability of the device. Overall, the practicality and environmental protection performance of the anti-dust wall environmentally friendly grinding device are improved, and it has broad application prospects.
