Description

Technical Field

[0001] This utility model belongs to the technical field of bauxite powder waste, and in particular relates to a bauxite powder waste collection device. Background Technology

[0002] Bauxite powder waste is waste generated during the processing or use of bauxite. If it is discharged or improperly disposed of, bauxite powder waste will pollute the soil, water and atmosphere. Therefore, ventilation collection hoods are generally installed above or near the equipment where bauxite powder waste is disposed of in order to collect the flying waste dust and reduce dust overflow.

[0003] Because bauxite powder waste contains large dust particles, a filter cover is usually installed at the air inlet of the dust collector. Over time, dust accumulates on the surface of the filter cover, causing filter blockage and affecting waste collection. To address this, we propose a bauxite powder waste collection device to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a bauxite powder waste collection device that cleans and collects dust particles on the filter screen to prevent clogging, thereby solving the aforementioned technical problems.

A dust collector and a connecting pipe are detachably connected to one end of the collection pipe away from the ventilation duct. A filter plate is fixedly connected to one side of the inner cavity of the collection pipe. A filter bag is detachably connected to the inner surface of the connecting pipe. A collection box is connected to the bottom of the collection pipe and to the left of the filter plate. A rotating rod is rotatably connected to the inner cavity of the collection pipe through a sealed bearing. A scraper is detachably connected to one end of the rotating rod. One end of the scraper is tightly fitted with the filter plate. The end of the rotating rod that passes through the outside of the collection pipe is connected through a driving structure.

[0006] Preferably, the drive structure includes a stepper motor fixedly connected to the top of one side of the collecting tube, the output shaft of the stepper motor being fixedly connected to a driving bevel gear, the surface of the driving bevel gear meshing with a driven bevel gear, and the axis of the driven bevel gear being fixedly sleeved with the outer surface of the rotating rod.

[0007] Preferably, a one-way valve is movably connected to the surface of the ventilation duct.

[0008] Preferably, the surface of the rotating rod is fitted with a mounting sleeve, and the mounting sleeve is fixedly connected to the rotating rod by mounting bolts.

[0009] Preferably, the surface of the mounting sleeve is fixedly connected to the scraper, and there are multiple scrapers, which are inclinedly arranged on the surface of the mounting sleeve.

[0010] Preferably, one side of the inner cavity of the collection box is designed to be inclined, and the bottom of the collection box is detachably connected to a cover plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a dust extraction fan to draw dust into a collection pipe, where larger particles are filtered through a filter plate, and smaller particles are filtered through a filter bag. Small dust particles are collected. When it is necessary to clean and collect the dust on the surface of the filter plate, the drive structure rotates the rotating rod, which in turn rotates the scraper. The scraper removes the dust from the surface of the filter plate, causing the dust to fall into the collection box for centralized processing. By setting up the above structure, the dust particles on the filter screen are cleaned and collected, avoiding clogging.

[0013] 2. This utility model uses a stepper motor to drive the active bevel gear to rotate, and the rotation of the active bevel gear drives the driven bevel gear to rotate, thereby driving the rotating rod to rotate, so that the scraper is in contact with and rotates on the surface of the filter plate.

[0014] 3. By setting a one-way valve, this utility model can prevent dust backflow when the surface of the filter plate needs to be cleaned.

[0015] 4. This utility model has multiple scrapers that are set at an angle on the surface of the mounting sleeve. The angled design makes cleaning easier and helps to remove dust adhering to the surface of the filter plate. Attached Figure Description

[0023] In the following description, embodiments of the bauxite powder waste collection device of the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-4 This invention illustrates an embodiment of a bauxite powder waste collection device, comprising a collection pipe 2 connected to the top of a ventilation duct 1. A dust collector 3 and a connecting pipe 4 are detachably connected sequentially to one end of the collection pipe 2 away from the ventilation duct 1. A filter plate 5 is fixedly connected to one side of the inner cavity of the collection pipe 2. A filter bag 6 is detachably connected to the inner surface of the connecting pipe 4. A collection box 7 is connected to the bottom of the collection pipe 2, located to the left of the filter plate 5. A rotating rod 8 is rotatably connected to the inner cavity of the collection pipe 2 via a sealed bearing. A scraper 9 is detachably connected to one end of the rotating rod 8. An mounting sleeve is fitted onto the surface of the rotating rod 8, and the mounting sleeve is fixedly connected to the rotating rod 8 via mounting bolts. The surface of the mounting sleeve is fixedly connected to the scraper 9. Multiple scrapers 9 are arranged at an angle on the surface of the mounting sleeve. The scraper 9 is tilted on the surface of the mounting sleeve. The tilted design makes cleaning easier and helps to remove dust adhering to the surface of the filter plate 5. One end face of the scraper 9 is tightly fitted with the filter plate 5. The end face of the rotating rod 8 that passes through the outside of the collection tube 2 is connected by a drive structure. The drive structure includes a stepper motor 10 fixedly connected to the top of one side of the collection tube 2. The output shaft of the stepper motor 10 is fixedly connected to a drive bevel gear 11. The surface of the drive bevel gear 11 meshes with a driven bevel gear 12. The stepper motor 10 drives the drive bevel gear 11 to rotate. The rotation of the drive bevel gear 11 drives the driven bevel gear 12 to rotate, thereby driving the rotating rod 8 to rotate, so that the scraper 9 fits and rotates on the surface of the filter plate 5. The shaft of the driven bevel gear 12 is fixedly sleeved with the outer surface of the rotating rod 8.

[0026] Dust is drawn into the collection pipe 2 by the vacuum fan 3, and larger particles are filtered by the filter plate 5, while finer particles are filtered by the filter bag 6. Small dust particles are collected. When it is necessary to clean and collect the dust on the surface of the filter plate 5, the drive structure drives the rotating rod 8 to rotate, which in turn drives the scraper 9 to rotate. The scraper 9 then removes the dust from the surface of the filter plate 5, causing the dust to fall into the collection box 7 for centralized processing. By setting up the above structure, the dust particles on the filter screen are cleaned and collected, avoiding clogging.

[0027] Example 2:

[0028] Figure 1-4 This invention illustrates an embodiment of a bauxite powder waste collection device, comprising a collection pipe 2 connected to the top of a ventilation duct 1. A one-way valve 13 is movably connected to the surface of the ventilation duct 1. By setting the one-way valve 13, when it is necessary to clean the surface of the filter plate 5, the one-way valve 13 can be closed to prevent dust backflow. A dust extraction fan 3 and a connecting pipe 4 are detachably connected to the end face of the collection pipe 2 away from the ventilation duct 1. A filter plate 5 is fixedly connected to one side of the inner cavity of the collection pipe 2. A filter bag 6 is detachably connected to the inner surface of the connecting pipe 4. A collection box 7 is connected to the bottom of the collection pipe 2 and to the left of the filter plate 5. One side of the inner cavity of the collection box 7 is inclined. A cover plate is detachably connected to the bottom of the collection box 7. A rotating rod 8 is rotatably connected to the inner cavity of the collection pipe 2 through a sealed bearing. A scraper 9 is detachably connected to one end face of the rotating rod 8. One end face of the scraper 9 is tightly fitted with the filter plate 5. The end face of the rotating rod 8 that passes through the outside of the collection pipe 2 is connected by a drive structure.

[0029] Working principle: When this utility model is in use, the dust is drawn into the collection pipe 2 by the dust suction fan 3, and larger particles are filtered by the filter plate 5, while fine particles are filtered by the filter bag 6 and small dust particles are collected. When it is necessary to clean and collect the dust on the surface of the filter plate 5, the stepper motor 10 drives the active bevel gear 11 to rotate. The rotation of the active bevel gear 11 drives the driven bevel gear 12 to rotate, which in turn drives the rotating rod 8 to rotate. This causes the scraper 9 to rotate and adhere to the surface of the filter plate 5, removing the dust from the surface of the filter plate 5. The dust falls into the collection box 7 for centralized processing, thus achieving the purpose of cleaning and collecting dust particles on the filter screen and avoiding clogging.
