Description

Technical Field

[0001] This utility model relates to the technical field of dust reduction, and in particular to an integrated dust reduction structure for a grinding mill. Background Technology

[0002] The grinding mill is a continuous feeding type, simple and convenient to operate, suitable for on-site processing of various grains and Chinese medicinal materials in supermarkets, shopping malls, and shop stalls. It has a wide processing range, including various grains and Chinese medicinal materials. However, during operation, the grinding mill generates a large amount of dust, which, if not handled promptly, can cause environmental pollution and harm to users. Existing technology announcement CN214765709U proposes an integrated grinding mill with a dust-reducing structure, including an outer shell. A feed hopper is fixedly connected to the upper end of the outer shell, and a closing plate is fixedly connected to the upper end of the feed hopper. The outer shell contains grinding blocks, and a first filter plate is located below the grinding blocks. The left end of the first filter plate is rotatably connected to the outer shell, and a discharge pipe is fixedly connected to the lower end of the outer shell. A dust collection pipe is fixedly connected to the upper left side of the outer shell, and an exhaust fan is fixedly connected inside the dust collection pipe. However, the dust removal effect is poor; some dust overflows from the top of the feed hopper during feeding, making dust recovery difficult and resulting in waste. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an integrated dust reduction structure for grinding mills that improves the absorption of dust generated during processing, enhances dust reduction effect, increases material utilization, and improves practicality.

A dust collection component is installed on the upper part of the grinding mill body, and a dust suction component is installed below it. A recovery component is connected to the bottom of the dust collection component, and a cleaning component is installed inside the dust collection component. Material is fed into the grinding mill body through the feeding hopper for processing. The dust suction component extracts dust from the dust collection component, allowing the dust generated during processing to enter the dust collection component. The cleaning component pushes and cleans the dust inside the dust collection component, and the recovery component re-inputs the dust into the grinding mill body, improving material utilization and practicality.

[0005] Preferably, the dust collection assembly includes a dust collection box, a first filter screen, a second filter screen, and multiple support rods.

Filter cartridges are installed at the input ends of the air extraction pipes, and the input ends of the filter cartridges are connected to the bottom of the dust collection box. The exhaust pipe is connected to the output end of the air extractor. When the exhaust pipe is activated, air is drawn into the dust collection box through the air extraction pipes to accelerate the absorption of dust and improve the dust reduction effect. The dust can be filtered through the filter cartridges.

[0007] Preferably, the cleaning assembly includes a lifting rotating ring, a rotating ring, multiple rotating plates, multiple cleaning brushes, a reduction motor, and gears. A lifting rotating groove is provided at the top of the dust collection box. The lifting rotating ring is rotatably installed inside the lifting rotating ring. A rotating ring is installed at the bottom of the lifting rotating ring. Multiple rotating plates are axially and evenly installed at the bottom of the rotating ring, and cleaning brushes are installed on the rotating plates.

The reduction motor is installed at the top left end of the dust collection box. A gear is installed at the output end of the reduction motor through the top of the dust collection box, and the gear meshes with the toothed ring. Starting the reduction motor drives the gear to rotate, which in turn drives the rotating ring to rotate. The rotating ring then drives the rotating plates and cleaning brushes to rotate, pushing and collecting the settled dust in the dust collection box for easy recycling.

[0008] Preferably, the recycling component includes a collection box, a discharge pipe, and a valve. The collection box is installed on the right side of the bottom of the dust collection box, and the output end of the collection box is connected to the discharge pipe, which is equipped with a valve. The collection box collects the settled dust, and opening the valve allows the collected dust to be discharged back into the main body of the grinding mill for reuse, reducing material waste.

[0009] Preferably, it also includes multiple support legs and a cover plate. The multiple support legs are respectively installed at the bottom of the main body of the grinding mill, and the cover plate is hinged to the top of the feeding hopper. The multiple support legs can support the bottom of the main body of the grinding mill to ensure stability during use, while the cover plate can protect the top of the feeding hopper to prevent dust from overflowing.

[0010] Preferably, it also includes two handles, which are installed at the front and rear ends of the top of the dust collection box; the two handles make it easy to carry the equipment, facilitate the movement of the equipment, and improve flexibility.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is added into the main body of the grinding mill through the feeding hopper for processing, the dust collection component can extract the dust generated during processing into the dust collection component, the cleaning component can push and clean the dust in the dust collection component, and the recycling component can re-input the dust into the main body of the grinding mill, thereby improving the material utilization rate and improving practicality.
