[0002] Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. Based on its excellent properties, it has been successfully used to cast parts subject to complex stresses and requiring high strength, toughness, and wear resistance. Ductile iron has rapidly developed into the second most widely used cast iron material after gray cast iron. In modern manufacturing, ductile iron castings are widely used in automobiles, machinery, energy, and many other fields due to their excellent mechanical properties.

This dust not only seriously endangers the health of operators, easily causing respiratory diseases, but also pollutes the workshop environment, affects the normal operation of other equipment, and even poses safety hazards such as dust explosions. In addition, traditional dust collection devices have problems such as low dust collection efficiency, inability to flexibly adapt to different grinding positions, and inconvenient cleaning.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a dust collection device for a grinding table used in the machining of ductile iron castings, comprising:

[0027] The support assembly 100 includes a housing 101, a support plate 102 fixedly connected to the middle position of the housing 101, a cover 103 fixedly connected to the upper end of the housing 101, and a baffle plate 104 inserted into the side wall of the cover 103. The baffle plate 104 is symmetrically installed on the side wall of the cover 103.

[0028] The dust collection assembly 200 includes a flow guide 201 rotatably mounted on the inner wall of the housing 103, a main shaft 202 rotatably mounted on the side wall of the support plate 102, an impeller 203 adapted to be mounted on the side wall of the main shaft 202, and a collection box 204 inserted into the housing 101. The bottom outlet of the flow guide 201 is connected to the collection box 204 through a pipe.

[0029] The support assembly 100 forms the basic framework of the entire dust collection device. A support plate 102 is installed in the middle of the outer shell 101 to provide a platform for other internal components. The hood 103 is used to shield the dust airflow generated during grinding, reducing the outward diffusion of dust. The baffle plate 104 is used to close the feed inlet of the hood 103, and its opening and closing angle can be flexibly adjusted according to actual usage needs. This design not only prevents dust from spreading in all directions but also facilitates the grinding operation of ductile iron castings by operators. The guide hood 201 is rotatably mounted on the inner wall of the hood 103 via precision bearings. Its unique curved design optimizes the airflow direction and improves dust collection efficiency. The bottom outlet of the guide hood 201 is connected to the collection box 204 through a well-sealed pipe, ensuring that dust can be smoothly transferred to the collection box 204. The main shaft 202 is rotatably mounted on the side wall of the support plate 102, and the impeller 203 is adapted to be mounted on the side wall of the main shaft 202, forming a rotating airflow generating unit. When the impeller 203 rotates, it can generate airflow, drive the dust-laden gas to move, and transport the gas through the pipeline to the collection box 204 for filtration.

[0030] Specifically, the dust collection assembly 200 also includes an adjustment rod 205 rotatably mounted on the side wall of the housing 101, and a worm gear 206 fixedly connected to the end of the adjustment rod 205. The teeth on the side wall of the worm gear 206 mesh with the worm wheel rack at the bottom of the guide shroud 201.

[0031] The operator can rotate the adjusting rod 205 to drive the worm gear 206 to rotate, thereby adjusting the angle of the guide shroud 201 and allowing the suction direction to be flexibly adjusted according to the grinding position.

[0032] Furthermore, the dust collection assembly 200 also includes a motor 207 fixedly connected to the middle of the lower end of the flow guide hood 201, and the output shaft of the motor 207 is connected to the bottom of the main shaft 202 for transmission.

[0033] The output shaft of the motor 207 is connected to the bottom of the main shaft 202 via a coupling or belt drive to provide power for the rotation of the impeller 203.

[0034] Furthermore, the dust collection assembly 200 also includes a filter element 208 that is sealed and inserted into the side wall of the collection box 204, with the end of the filter element 208 inserted into the middle of the internal channel of the collection box 204.

[0035] Filter element 208 is used to intercept dust particles, ensuring that the discharged gas is clean and pollution-free.

[0036] Preferably, the dust collection assembly 200 also includes an air pump 209 installed on the side wall of the collection box 204, with the air inlet of the air pump 209 connected to the interior of the collection box 204.

[0037] Among them, the air pump 209 can accelerate the airflow inside the collection box 204, improve the dust collection efficiency, and help the dust settle inside the collection box 204.

[0038] It should be noted that the dust collection assembly 200 also includes a waste box 210 that is snapped onto the lower side wall of the flow guide shroud 201, and the waste box 210 is located outside the impeller 203.

[0039] The waste box 210 can be used to collect larger particles of waste intercepted by the impeller 203 during rotation, making it convenient for centralized cleaning.

[0040] Preferably, the support assembly 100 further includes an extension plate 105 hinged to the side wall of the housing 101, and a cylinder 106 hinged to the side wall of the housing 101, with the output end of the cylinder 106 hinged to the lower end of the extension plate 105.

[0041] The cylinder 106 hinged to the lower end of the extension plate 105 can precisely adjust the angle of the extension plate 105 by controlling the extension and retraction of the cylinder 106, so as to meet the needs of different application scenarios.

[0042] During operation, when the ductile iron casting is being processed on the grinding table, the motor 207 is started. The motor 207 drives the main shaft 202 to rotate, which in turn causes the impeller 203 to rotate at high speed, creating a negative pressure airflow inside the housing 103. At this time, the dust generated during grinding is sucked into the housing 103 under the negative pressure and, guided by the guide shroud 201, enters the collection box 204 through the pipe. The operator can rotate the adjusting rod 205 to adjust the angle of the guide shroud 201 according to the actual grinding position, so that the dust suction port can be aligned with the dust source to improve the dust suction effect. After the dust enters the collection box 204, the air pump 209 is started, accelerating the airflow inside the collection box 204, causing the dust to quickly settle at the bottom of the collection box 204, while the clean air filtered by the filter element 208 is discharged from the air outlet of the air pump 209. During the grinding process, larger particles of waste intercepted by the impeller 203 will fall into the waste box 210, which is convenient for the operator to clean regularly. Meanwhile, operators can adjust the angle of the extension plate 105 by controlling the extension and retraction of the cylinder 106 as needed to obtain a more comfortable operating space or place tools.

[0043] In summary, by using a motor-driven impeller to generate negative pressure airflow, combined with an adjustable-angle guide hood, the system can precisely target dust sources for suction, improving suction efficiency, effectively reducing dust emissions in the workshop, and improving the working environment. The guide hood's angle is flexibly adjustable to adapt to grinding operations on ductile iron castings at different positions and angles, enhancing the device's applicability. The design of the waste box and collection bin facilitates the centralized cleaning of collected waste and dust. The filter element ensures the cleanliness of the exhaust gas, meeting environmental protection requirements and preventing secondary pollution.
