Description

Technical Field

[0001] This utility model belongs to the field of dust collection technology, and in particular to a powder dust collection device. Background Technology

[0002] Powder processing equipment generates a large amount of dust during the processes of powder crushing, feeding, mixing, blending, unloading, conveying, and transferring. If not handled promptly, this dust will not only affect the workshop working environment but also waste raw materials. During mixing and temporary storage, exhaust ventilation is necessary to collect the dust and prevent its spread, which could impact the working environment and personnel.

[0003] However, during collection, there is no oscillation or vibration function, and powder and dust easily accumulate in the fan and filtration equipment, affecting subsequent continuous operation. Utility Model Content

[0004] The purpose of this invention is to provide a powder dust collection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a powder dust collection device, comprising a centrifugal fan for collecting powder dust, an auxiliary tower provided on one side of the centrifugal fan, a storage frame detachably connected to the side of the outlet of the centrifugal fan, a filter frame detachably connected to the inner wall of the storage frame, a filter screen for filtering powder dust connected to the inner wall of the filter frame, and a discharge channel corresponding to the position of the filter frame opened at the bottom of the storage frame.

[0006] Multiple auxiliary blocks are installed on the outer periphery of both the centrifugal fan and the storage frame. Hollow tubes are connected to the outer periphery of the auxiliary blocks. Movable rods are installed inside the hollow tubes. Rotating rods are rotatably connected between two corresponding movable rods. Multiple eccentric wheels for excitation are connected to the outer periphery of the rotating rods. Springs are connected between the movable rods and the auxiliary blocks. A micro motor that provides power to the rotating rod is installed on the outer periphery of one of the movable rods.

[0007] As a preferred embodiment, the centrifugal fan is connected to the auxiliary tower through an air inlet pipe, and a support frame is detachably connected to the side of the auxiliary tower by multiple bolts. The support frame is detachably connected to the centrifugal fan.

[0008] As a preferred embodiment, the bottom of the storage frame is detachably connected to a receiving bag corresponding to the position of the discharge channel.

[0009] As a preferred embodiment, a dust filter bag is detachably connected to the side of the storage frame away from the centrifugal fan.

[0010] As a preferred embodiment, a linear motor is embedded in the inner top wall of the storage frame, and the moving part of the linear motor is connected to a cleaning brush for cleaning the filter screen.

[0011] As a preferred embodiment, the centrifugal fan has a discharge channel at its bottom, and the inner wall of the discharge channel is rotatably connected to two movable plates, which are fixed by a locking mechanism.

[0012] As a preferred embodiment, the bottom of the centrifugal fan is detachably connected to a collection bag that is connected to two movable plates.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] The powder dust collection equipment uses a centrifugal fan to extract air from the auxiliary tower, creating a negative pressure inside the tower. This prevents the powder and dust inside from flowing out of the auxiliary tower with the air, thus avoiding their spread and impact on the working environment and personnel.

[0015] In this powder dust collection equipment, when the centrifugal fan is drawing air, the filter screen of the filter frame can filter the air, and the dust collection filter bag can further filter the air. During filtration, the linear motor drives the cleaning brush to move back and forth, thereby cleaning the filter screen. This not only prevents the filter screen from being clogged, but also sweeps the filtered material into the receiving bag, ensuring continuous operation.

[0016] When the centrifugal fan is working, or when it is being disassembled and cleaned, the micro motor drives the rotating rod to rotate, which in turn drives the eccentric wheel to rotate, thereby vibrating the centrifugal fan and the storage frame, shaking off the powder and dust, and preventing the powder and dust from accumulating and affecting the centrifugal fan and the storage frame.

[0017] This powder dust collection equipment can not only process powder dust, but also perform filtration and vibration treatment. Attached Figure Description

[0029] Because this application is located in a dusty environment, all instruments and structures are dustproofed and regularly disassembled for maintenance. They cannot be used or operated continuously for extended periods.

[0030] Please see Figures 1 to 4As shown, a powder dust collection device is provided. In this embodiment, it includes a centrifugal fan 1 for collecting powder dust. An auxiliary tower 2 is provided on one side of the centrifugal fan 1. A storage frame 3 is detachably connected to the side of the air outlet of the centrifugal fan 1. A dust removal filter bag 16 is detachably connected to the side of the storage frame 3 away from the centrifugal fan 1. A filter frame 4 is detachably connected to the inner wall of the storage frame 3. A filter screen 5 for filtering powder dust is connected to the inner wall of the filter frame 4. When the centrifugal fan 1 operates, it can draw air out of the auxiliary tower 2. When the air enters the storage frame 3, the filter screen 5 of the filter frame 4 can filter the air, and the dust removal filter bag 16 can further filter the air.

[0031] Multiple auxiliary blocks 6 are installed on the outer periphery of both the centrifugal fan 1 and the storage frame 3. Hollow tubes 7 are connected to the outer periphery of the auxiliary blocks 6. Movable rods 8 are installed inside the hollow tubes 7. Rotating rods 9 are rotatably connected between two corresponding movable rods 8. Multiple eccentric wheels 10 for excitation are connected to the outer periphery of the rotating rods 9. Springs 11 are connected between the movable rods 8 and the auxiliary blocks 6. A micro motor 12 is installed on the outer periphery of one of the movable rods 8 to provide power to the rotating rod 9. The micro motor 12 drives the rotating rod 9 to rotate, which in turn drives the eccentric wheels 10 to rotate, thereby exciting the centrifugal fan 1 and the storage frame 3 to shake off powder and dust, preventing the accumulation of powder and dust from affecting the centrifugal fan 1 and the storage frame.

[0032] Centrifugal fan 1 is connected to auxiliary tower 2 through an air inlet pipe. A support frame 14 is detachably connected to the side of auxiliary tower 2 by multiple bolts. The support frame 14 is detachably connected to centrifugal fan 1.

[0033] For cleaning, a linear motor 17 is embedded in the inner top wall of the storage frame 3. The moving part of the linear motor 17 is connected to a cleaning brush 18 for cleaning the filter screen 5. The bottom end of the storage frame 3 has a discharge channel corresponding to the position of the filter frame 4. The bottom end of the storage frame 3 is detachably connected to a receiving bag 15 corresponding to the position of the discharge channel. The linear motor 17 drives the cleaning brush 18 to move back and forth, thereby cleaning the filter screen 5. This not only prevents the filter screen 5 from being blocked, but also sweeps the filtered material into the receiving bag 15, ensuring continuous operation.

[0034] To meet usage requirements, a discharge channel is provided at the bottom of the centrifugal fan 1. Two movable plates 19 are rotatably connected to the inner wall of the discharge channel. The two movable plates 19 are fixed by a locking mechanism. The movable plates 19 are opened periodically to retrieve materials. A collection bag 20 connected to the two movable plates 19 is detachably connected to the bottom of the centrifugal fan 1.

[0035] The dust collector filter bag 16, receiving bag 15, and collecting bag 20 are all periodically disassembled and used for material removal.

[0036] Centrifugal fan 1, storage tower 2, micro motor 12, and linear motor 17 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0037] Working principle

[0038] The powder dust collection equipment uses a centrifugal fan 1 to extract air from the auxiliary tower 2. When the air enters the storage frame 3, the filter screen 5 of the filter frame 4 can filter the air, and the dust removal filter bag 16 can further filter the air.

[0039] During filtration, the linear motor 17 drives the cleaning brush 18 to move back and forth, thereby cleaning the filter screen 5. This not only prevents the filter screen 5 from becoming clogged, but also sweeps the filtered material into the receiving bag 15, ensuring continuous operation. The micro motor 12 drives the rotating rod 9 to rotate, which in turn drives the eccentric wheel 10 to rotate, thereby vibrating the centrifugal fan 1 and the storage frame 3, shaking off the powder and dust, and preventing the accumulation of powder and dust from affecting the centrifugal fan 1 and the storage frame 3.
