Description

Technical Field

[0001] This utility model relates to the field of ventilation and dust removal machine technology, and in particular to a ventilation and dust removal machine for powder silos. Background Technology

[0002] The powder silo ventilation and dust removal machine is a device specifically designed for ventilation and dust removal within powder silos. Its main function is to introduce fresh air and expel polluted air while removing dust particles from the air to maintain air quality within the powder silo, ensuring a safe working environment and employee health. This equipment is widely used in various industries that require the processing of powdery materials, such as cement, chemical, pharmaceutical, and food processing. In these industries, powder silos are important facilities for storing and processing powdery materials. However, during the loading, unloading, and transportation of materials, a large amount of dust is generated, which not only pollutes the environment but may also cause safety accidents such as explosions.

[0003] Existing dust collectors for powder silos mainly rely on bag filters. When dust-laden air passes through a bag filter, dust particles are intercepted, filtered, or adsorbed onto the bag filter. Over time, this causes excessive dust to adhere to the bag filter, reducing its filtration efficiency. Furthermore, the dust collection box requires manual disassembly and cleaning after the machine is stopped, impacting production efficiency.

[0004] Therefore, there is an urgent need to provide a powder silo ventilation and dust removal machine to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a powder silo ventilation and dust removal machine.

[0006] To solve the above-mentioned technical problems, the present invention provides a powder silo ventilation and dust removal machine, including a ventilation and dust removal machine shell, an air inlet pipe fixedly installed on one side of the ventilation and dust removal machine shell, an air outlet pipe fixedly installed on the other side of the ventilation and dust removal machine shell, a top shell fixedly installed on the top of the ventilation and dust removal machine shell, a vibration mechanism provided inside the top shell, a dust removal mechanism provided inside the ventilation and dust removal machine shell, and a dust discharge mechanism provided inside the ventilation and dust removal machine shell.

[0007] Through the above technical solution, the fan draws air from the powder silo into the outer shell of the air exchange dust collector through the air inlet pipe, and the filtered air is discharged through the air outlet pipe.

[0008] The present invention is further configured such that: the vibration mechanism includes a dual-axis motor fixed to the top of the housing of the air exchange dust collector; the output shaft of the dual-axis motor is fixedly connected to two elliptical plate shafts through a coupling; and four lifting slide rods are slidably installed inside the housing of the air exchange dust collector.

[0009] The above technical solution enables a dual-axis motor to drive the two elliptical plate shafts to rotate.

[0010] The present invention is further configured such that: two reciprocating slide plates are fixedly installed at the top of the four lifting slide rods, the interior of the reciprocating slide plates is slidably connected to the outer surface of the elliptical plate shaft, a lifting frame is fixedly installed at the bottom of the reciprocating slide plates, and a flexible connecting rubber is fixedly connected between the lifting frame and the inner wall of the air exchange dust collector housing.

[0011] With the above technical solution, when the elliptical plate shaft rotates, it drives the reciprocating slide plate to drive the lifting slide rod and the lifting frame to reciprocate up and down, and the soft connecting rubber seals the connection between the lifting frame and the outer shell of the air exchange dust collector.

[0012] The present invention is further configured such that: the ash removal mechanism includes a fixed frame fixed to the inner wall of the air exchange dust collector housing, a bag frame is fixedly installed inside the fixed frame, the outer surface of the bag frame is slidably connected to the inside of the lifting frame, and a dust collector bag is fixedly connected between the fixed frame and the lifting frame.

[0013] Through the above technical solution, the lifting frame drives the dust collector bag to shake through the fixed frame, which can effectively shake off the dust particles attached to the outer surface of the dust collector bag and the gaps between the fibers, while the bag frame maintains the shape of the dust collector bag.

[0014] The present invention is further configured such that: a dust collection shell is fixedly installed at the bottom end of the fixed frame, a dust discharge pipe is fixedly installed at the bottom end of the dust collection shell, and a dust collection drawer is fitted inside the dust discharge pipe.

[0015] Through the above technical solution, dust particles are collected by the dust collection shell and fall into the dust collection drawer through the dust discharge pipe.

[0016] The present invention is further configured such that: the back of the dust removal mechanism is fixed to the mounting shell on one side of the ash discharge pipe, an electric lifting rod is fixedly installed on the inner bottom wall of the mounting shell, a synchronization plate is fixedly installed on one end of the piston rod of the electric lifting rod, and a telescopic rod is fixedly connected between the synchronization plate and the inner bottom wall of the mounting shell.

[0017] Through the above technical solution, the electric lifting rod drives the synchronous plate to rise and fall through the telescopic rod.

[0018] The present invention is further configured such that: a rack is fixedly installed at the top of the synchronization plate; a ash discharge roller with one end penetrating through and extending into the interior of the ash discharge shell is rotatably installed inside the ash discharge shell; a gear is fixedly installed on the outer surface of the ash discharge roller; and the outer surface of the gear meshes with one side of the rack.

[0019] Through the above technical solution, the synchronous plate drives the rack to rise and fall, and the rack drives the gear and the ash discharge roller to rotate. When the opening of the ash discharge roller is at the top, the dust particles fall into the inside of the ash discharge roller. Then the ash discharge roller rotates ninety degrees and pours the dust particles into the ash collection drawer.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, by providing a vibration mechanism and a dust removal mechanism, can drive the dust collector bag to vibrate, which can effectively shake off the dust particles attached to the outer surface of the dust collector bag and the gaps between the fibers, maintain the good air permeability of the dust collector bag, thereby ensuring the continuity of the filtration effect, so that the dust collector bag will not suffer uneven wear due to excessive local dust accumulation, and improve the service life of the dust collector bag.

[0022] 2. This utility model, by providing a dust removal mechanism and an ash discharge mechanism, can automatically discharge the filtered dust particles when the dust in the ash collection box reaches a certain amount during equipment operation. This eliminates the need to stop the equipment to clean the dust, ensuring continuous production and greatly improving production efficiency. Attached Figure Description

An air inlet pipe 2 is fixedly installed on one side of the ventilation and dust removal machine housing 1, and an air outlet pipe 3 is fixedly installed on the other side of the ventilation and dust removal machine housing 1. A top shell 4 is fixedly installed on the top of the ventilation and dust removal machine housing 1. A vibration mechanism 5 is provided inside the top shell 4. The vibration mechanism 5 includes a dual-shaft motor 501 fixed to the top of the ventilation and dust removal machine housing 1. The output shaft of the dual-shaft motor 501 is fixedly connected to two elliptical plate shafts 502 through a coupling. Four lifting slide rods 503 are slidably installed inside the ventilation and dust removal machine housing 1. Two reciprocating slide plates 504 are fixedly installed on the top of the four lifting slide rods 503. The interior of the reciprocating slide plates 504 is slidably connected to the outer surface of the elliptical plate shafts 502. A lifting frame 505 is fixedly installed at the bottom of the reciprocating slide plate 504. A flexible rubber connection 506 is fixedly connected between the lifting frame 505 and the inner wall of the air exchange dust collector housing 1. The fan draws air from the powder silo into the air exchange dust collector housing 1 through the air inlet pipe 2. The filtered air is discharged through the air outlet pipe 3. The dual-shaft motor 501 drives the two elliptical plate shafts 502 to rotate. The top shell 4 protects them from interference from the external environment. When the elliptical plate shafts 502 rotate, they drive the reciprocating slide plate 504 to drive the lifting slide rod 503 and the lifting frame 505 to reciprocate and lift. The flexible rubber connection 506 seals the connection between the lifting frame 505 and the air exchange dust collector housing 1 to prevent air from escaping through the gap between the lifting frame 505 and the air exchange dust collector housing 1.

[0033] like Figures 4-6As shown, the dust collector housing 1 is equipped with a dust removal mechanism 7 inside. The dust removal mechanism 7 includes a fixing frame 701 fixed to the inner wall of the dust collector housing 1. A bag filter frame 702 is fixedly installed inside the fixing frame 701. The outer surface of the bag filter frame 702 is slidably connected to the inside of the lifting frame 505. A dust collector bag 703 is fixedly connected between the fixing frame 701 and the lifting frame 505. A dust collection shell 704 is fixedly installed at the bottom end of the fixing frame 701. A dust discharge pipe 705 is fixedly installed at the bottom, and a dust collection drawer 706 is fitted inside the dust discharge pipe 705. The lifting frame 505 drives the dust collector bag 703 to shake through the fixed frame 701, which can effectively shake off the dust particles attached to the outer surface of the dust collector bag 703 and the gaps between the fibers. The dust particles are collected through the dust collection shell 704 and fall into the dust collection drawer 706 through the dust discharge pipe 705. The bag frame 702 maintains the shape of the dust collector bag 703.

[0034] like Figures 2-7 As shown, a dust removal mechanism 6 is installed inside the outer casing 1 of the air exchange dust collector. The back of the dust removal mechanism 6 is fixed to the mounting shell 601 on one side of the ash discharge pipe 705. An electric lifting rod 602 is fixedly installed on the inner bottom wall of the mounting shell 601. A synchronous plate 603 is fixedly installed at one end of the piston rod of the electric lifting rod 602. A telescopic rod 604 is fixedly connected between the synchronous plate 603 and the inner bottom wall of the mounting shell 601. A rack 605 is fixedly installed at the top of the synchronous plate 603. A discharge pipe with one end penetrating and extending into the interior of the mounting shell 601 is rotatably installed inside the ash discharge shell 704. The outer surface of the ash roller 606 is fixedly equipped with a gear 607. The outer surface of the gear 607 meshes with one side of the rack 605. The electric lifting rod 602 drives the synchronous plate 603 to rise and fall through the telescopic rod 604. The synchronous plate 603 drives the rack 605 to rise and fall. The rack 605 drives the gear 607 and the ash roller 606 to rotate. When the opening of the ash roller 606 is at the top, the dust particles fall into the ash roller 606. Then the ash roller 606 rotates ninety degrees and pours the dust particles into the ash collection drawer 706.

[0035] In use, the fan draws air from the powder silo into the outer casing 1 of the ventilation and dust collector through the inlet pipe 2. The air is filtered by the dust collector bag 703 and then discharged through the outlet pipe 3. The dual-shaft motor 501 drives two elliptical plate shafts 502 to rotate, protected by the top shell 4 to prevent interference from the external environment. As the elliptical plate shafts 502 rotate, they drive the reciprocating slide plate 504, which in turn drives the lifting slide bar 503 and the lifting frame 505 to reciprocate. A flexible rubber connection 506 seals the gap between the lifting frame 505 and the outer casing 1 of the ventilation and dust collector, preventing air from escaping through the gap. The lifting frame 505 causes the dust collector bag 703 to vibrate via the fixing frame 701. It can effectively shake off the dust particles attached to the outer surface and fiber gaps of the dust collector bag 703. The dust particles are collected through the dust collection shell 704 and fall into the dust collection drawer 706 through the dust discharge pipe 705. The bag frame 702 maintains the shape of the dust collector bag 703. The electric lifting rod 602 drives the synchronous plate 603 to rise and fall through the telescopic rod 604. The synchronous plate 603 drives the rack 605 to rise and fall. The rack 605 drives the gear 607 and the dust discharge roller 606 to rotate. When the opening of the dust discharge roller 606 is at the top, the dust particles inside the dust collection shell 704 fall into the dust discharge roller 606. Then the dust discharge roller 606 rotates ninety degrees and pours the dust particles into the dust collection drawer 706.
