Description

Technical Field

[0001] This utility model relates to the field of dust collection structure technology, specifically a novel dust collection structure for a floor grinder. Background Technology

[0002] A floor grinder is a professional, high-efficiency mechanical device used for floor treatment, widely applied to surface treatment of various materials such as concrete, stone, terrazzo, and epoxy flooring. Its core functions include deep cleaning, removal of old coatings, surface smoothness restoration, and polishing and waxing. It significantly improves the smoothness, wear resistance, and anti-slip properties of the floor, making it suitable for floor renovation and routine maintenance in various commercial and industrial locations such as airports, shopping malls, factories, and warehouses. Through mechanized operation, floor grinders not only greatly improve work efficiency but also ensure that the treated floor achieves professional-grade aesthetics and functionality, making it an indispensable tool in modern building maintenance.

[0003] Ground grinding operations generate a large amount of dust, which not only pollutes the environment but also endangers workers' health. In the current technology, grinding machines are usually equipped with ordinary dust collection equipment, but their filter structure is simple and lacks effective self-cleaning ability. Under continuous high dust load, they are prone to clogging, which leads to a rapid decline in system suction power. In order to avoid a decrease in efficiency, it is necessary to frequently interrupt the operation for manual cleaning or filter replacement, which seriously restricts the continuity of construction and overall efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel dust collection structure for a floor grinder, thereby solving the problem mentioned in the background art where existing floor grinder dust collection equipment suffers from easily clogged filters, leading to reduced suction power and requiring frequent shutdowns for cleaning, thus affecting the continuity of construction.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel dust collection structure for a floor grinder, comprising a dust collection bin, a shaped filter cover fixedly installed on the top of the dust collection bin by a locking buckle, a filter element provided in the inner cavity of the dust collection bin, a vibration dust removal motor fixedly installed inside the filter element, a vibration isolation pad provided on the top of the filter element, a back-blowing dust removal valve fixedly installed on the top of the shaped filter cover, a first conduit fixedly connected to one side of the shaped filter cover, a second conduit and a third conduit fixedly connected inside the dust collection bin, both the second and third conduits extending to the outside of the dust collection bin, and a dust discharge valve provided at the bottom opening of the dust collection bin.

[0006] Preferably, a shaped protective cover is fixedly connected to the upper surface of the shaped filter barrel cover, and the back-blowing dust removal valve is located in the inner cavity of the shaped protective cover.

[0007] Preferably, an annular mounting plate is fixedly connected to the upper part of the inner wall of the dust collection bin, the upper surface of the filter element is connected to the vibration isolation pad by bolts, and the upper surface of the vibration isolation pad is connected to the annular mounting plate by bolts.

[0008] Preferably, a flow guide is fixedly connected to the top of the inner cavity of the filter barrel cover, the back-blowing dust removal valve is located directly above the flow guide, and the flow guide is located directly above the filter element.

[0009] Preferably, an inclined inlet baffle is fixedly connected to the inner wall of the dust collection bin, and the inclined inlet baffle is located in front of the end of the second duct.

[0010] Preferably, a dust guide cover is fixedly connected to the lower part of the outer surface of the dust collection bin, and the dust discharge valve is disposed in the inner cavity of the dust guide cover.

[0011] Beneficial effects

[0012] This utility model provides a novel dust collection structure for a floor grinder. It has the following beneficial effects:

[0013] The dust collection structure of this new type of floor grinder achieves automatic and efficient cleaning of the filter element through a synergistic dust removal mechanism that integrates a vibrating dust removal motor and a high-pressure back-blowing dust removal valve. The vibrating motor causes the filter element to vibrate at high frequency and micro-amplitude, effectively shaking off the dust adhering to the surface. At the same time, the high-pressure airflow generated by the back-blowing valve is guided by the guide hood and blows vertically downwards to back-blow the inside of the filter element, removing deep-seated fine dust. The two work together to ensure that the filter element maintains a low-resistance state, significantly improving dust collection efficiency and automation, and reducing manual intervention. This device can be combined with a floor grinder to achieve integrated grinding and dust collection. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, this utility model provides a novel dust collection structure for a floor grinder, including a dust collection bin 1. A shaped filter cover 2 is fixedly installed on the top of the dust collection bin 1 by a locking buckle. A filter element 5 is provided in the inner cavity of the dust collection bin 1. A vibration dust removal motor 6 is fixedly installed inside the filter element 5. A vibration isolation pad 7 is provided on the top of the filter element 5. A back-blowing dust removal valve 9 is fixedly installed on the top of the shaped filter cover 2. A first conduit 10 is fixedly connected to one side of the shaped filter cover 2. A second conduit 11 and a third conduit 12 are fixedly connected inside the dust collection bin 1. Both the second conduit 11 and the third conduit 12 extend to the outside of the dust collection bin 1. A dust discharge valve 14 is provided at the bottom opening of the dust collection bin 1.

[0021] Specifically, a protective cover 3 is fixedly connected to the upper surface of the shape filter cover 2, and a back-flushing dust removal valve 9 is set in the inner cavity of the protective cover 3. The protective cover 3 can effectively protect the back-flushing dust removal valve 9 in its inner cavity from external collisions or foreign object interference, ensuring its working reliability.

[0022] Specifically, an annular mounting plate 4 is fixedly connected to the upper part of the inner wall of the dust collection bin 1. The upper surface of the filter element 5 is connected to the vibration isolation pad 7 by bolts. The upper surface of the vibration isolation pad 7 is connected to the annular mounting plate 4 by bolts. The annular mounting plate 4 provides a stable installation base for the entire vibration cleaning module. The vibration generated by the vibration dust removal motor 6 is effectively absorbed and isolated by the vibration isolation pad 7, which greatly reduces the vibration transmission to the dust collection bin 1 and the whole machine, and improves the stability of the equipment.

[0023] Specifically, a flow guide hood 8 is fixedly connected to the top of the inner cavity of the filter barrel cover 2. The back-blowing dust removal valve 9 is located directly above the flow guide hood 8. The flow guide hood 8 is located directly above the filter element 5. The flow guide hood 8 can gather and guide the high-pressure airflow blown down by the back-blowing dust removal valve 9, so that it blows vertically into the interior of the filter element 5.

[0024] Specifically, the inner wall of the dust collection bin 1 is fixedly connected with an inclined inlet baffle plate 13. The inclined inlet baffle plate 13 is located in front of the end of the second duct 11. The inclined inlet baffle plate 13 can block and buffer the dust-laden gas rushing in at high speed from the second duct 11, reduce the airflow speed, and cause large dust particles to fall directly into the bottom of the dust collection bin 1 after impacting its surface under inertial action.

[0025] Specifically, a dust guide cover 15 is fixedly connected to the lower part of the outer surface of the dust collection bin 1, and a dust discharge valve 14 is set in the inner cavity of the dust guide cover 15. The dust guide cover 15 forms a channel for collecting and discharging dust, which can concentrate the dust discharged from the dust discharge valve 14 and guide it to a designated area to prevent dust from flying around when discharging dust.

[0026] The working principle of the above embodiments:

[0027] When the floor grinder is working, the generated dust enters the dust collection bin 1 through the inclined interface of the second duct 11 via the external grinding dust suction hood. The inclined inlet baffle 13 set in front of the second duct 11 initially blocks and guides the high-speed dust airflow, causing large dust particles to initially settle due to gravity and inertia. Fine dust rises with the airflow and is effectively intercepted and filtered when it passes through the filter element 5. Clean air passes through the filter element 5 into its internal clean chamber and flows upward. Finally, it is drawn out and discharged by the external dust suction fan through the first duct 10 on one side of the shaped filter bin cover 2. To maintain the continuous filtration efficiency of the filter element 5, the system is equipped with an automatic dust removal mechanism that works in conjunction with the vibration dust removal motor 6 and the back-blowing dust removal valve 9. The motor 6 is fixedly installed inside the filter element 5. The high-frequency micro-vibration generated during operation is directly transmitted to the entire filter element 5, causing the dust layer attached to its outer surface to loosen and fall off. At the same time, the back-blowing dust removal valve 9 is activated at regular intervals, blowing high-pressure airflow downwards. After being guided by the guide hood 8, it is blown back into the filter element 5, forming an airflow impact from the inside out, which effectively removes fine dust deep in the filter material. The dust that is shaken off and blown off eventually falls into the bottom of the dust collection bin 1 and is periodically discharged through the dust discharge valve 14 at the bottom. During this process, the filter element 5 is flexibly connected to the annular mounting plate 4 at the upper part of the dust collection bin 1 through the vibration isolation pad 7 at its top. The vibration isolation pad 7 can effectively absorb and isolate the vibration generated by the vibration dust removal motor 6, preventing it from being transmitted to the dust collection bin 1 and other structures of the main unit.
