Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, specifically relating to a dust removal device suitable for large funnels. Background Technology

[0002] In industrial sectors such as mining, metallurgical processing, and chemical material transfer, large hoppers serve as core equipment for material storage and unloading, generating significant amounts of dust during the unloading process. To control dust pollution, wet dust collection has become the mainstream method due to its high efficiency and economy. It captures dust and achieves gas-liquid separation through water washing methods such as spraying. However, existing wet scrubbing dust collection equipment faces numerous technical bottlenecks in wastewater filtration and recycling, severely impacting the long-term stable operation of the dust collection system.

[0003] Firstly, most water-washing dust removal devices use a simple combination of spray towers and sedimentation tanks, lacking efficient automatic filtration systems. After the dust-laden wastewater is treated by the spray tower, solid impurities such as silt and metal oxides easily accumulate in the circulating water tank. Because the settled impurities cannot be discharged in time, they not only clog the spray heads and reduce the atomization effect, but also lead to the deterioration of the circulating water quality. As the operating time increases, the turbidity of the water continuously rises, and the dust removal efficiency shows a significant downward trend, making it difficult to maintain a stable dust removal effect.

[0004] Secondly, although some equipment is equipped with filter cartridges or other filtration devices, it relies on manual cleaning and maintenance. Manual cleaning is not only time-consuming and labor-intensive, with each cleaning session typically taking several hours or even longer, but it also generates secondary dust during the cleaning process, which can harm the health of operators. Furthermore, the randomness and instability of manual cleaning makes it difficult to maintain consistent filter media cleanliness, directly affecting filtration efficiency, increasing the frequency of equipment downtime for maintenance, and reducing production continuity. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a dust removal device suitable for large funnels, solving the problems of inefficient filtration systems, reliance on manual cleaning, and deficiencies in automatic cleaning functions in existing large funnel water washing dust removal equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device suitable for large funnels, comprising a funnel, a dust collection component, a spray tower, and a self-cleaning filter component. The dust collection component is fixed at the discharge port of the funnel and is connected to the air inlet of the spray tower via a duct. The air outlet of the spray tower is connected to a fan. The self-cleaning filter component includes an isolation cover, which is installed in the liquid storage tank of the spray tower. A filter cartridge is installed on the inner side of the isolation cover, and a slot flush with the inner wall of the filter cartridge is opened on the side of the isolation cover. A rotating shaft is rotatably installed in the filter cartridge, and the rotating shaft is connected to a spiral plate via a connecting rod. The spiral plate is slidably connected to the inner wall of the filter cartridge. One end of the rotating shaft rotatably passes through the liquid storage tank of the spray tower and is connected to a reduction motor via a chain drive mechanism. The water inlet of the circulating pump in the spray tower is connected to the cavity inside the isolation cover via a pipe.

[0007] The beneficial effects of this utility model are as follows: dust is removed from the discharge port of the funnel by spraying, impurities adsorbed in the water are effectively filtered by the filter cartridge, and the spiral plate can effectively clean the filtered impurities on the inner wall of the filter cartridge when it rotates under the drive of the geared motor, so that the filter cartridge can perform filtration for a long time.

[0008] In order to enable the geared motor to stably drive the rotation of multiple shafts through the use of a chain drive mechanism; As a further improvement to the above technical solution: each of the shafts is equipped with two sprockets from a chain drive mechanism, and two adjacent shafts are connected by a set of chain drive mechanisms.

[0009] The beneficial effect of this improvement is that multiple chain drive mechanisms can stably transmit power to each rotating shaft.

[0010] In order to effectively scrub the inner wall of the filter cartridge; As a further improvement to the above technical solution: brush bristles are adhered to the side of the spiral plate facing the inner wall of the filter cylinder.

[0011] The beneficial effects of this improvement are: when the spiral plate rotates, it brushes the inner wall of the filter cartridge with bristles and pushes the impurities removed by the brushing to one side of the isolation cover.

[0012] To facilitate the removal of impurities conveyed by the spiral plate scrubber; As a further improvement to the above technical solution: a collection trough is formed between the side of the isolation cover with the slot and the inner wall of the liquid storage tank of the spray tower. A slot hole flush with the inner wall of the collection trough is opened on the liquid storage tank of the spray tower at one end of the collection trough, and a blind plate is installed at the slot hole. The blind plate is connected to the spray tower by bolts.

[0013] The beneficial effect of this improvement is that after the blind flange is removed, the impurities accumulated in the collection tank can be quickly discharged.

[0014] In order to effectively remove dust from the discharge port of the funnel; As a further improvement to the above technical solution: the dust collection assembly includes a flange tube, which is bolted to the discharge port flange of the funnel. A dust collection groove is welded to the outside of the flange tube, and one end of the air duct is connected to the side of the dust collection groove.

[0015] The beneficial effect of this improvement is that the dust overflowing from the hopper discharge port can be guided into the air duct by the dust collection trough.

[0016] To ensure the stability of the spiral plate rotation; As a further improvement to the above technical solution: the number of connecting rods is multiple, and the two ends of the connecting rods are respectively connected to a rotating shaft and a spiral plate.

[0017] The beneficial effect of this improvement is that multiple connecting rods can stably connect the rotating shaft and the spiral plate.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0021] Example 1: like Figure 1-6The following describes a dust removal device suitable for a large funnel: a funnel 1, a dust collection assembly 2, a spray tower 4, and a self-cleaning filter assembly 5. The dust collection assembly 2 is fixed at the discharge port of the funnel 1 and is connected to the air inlet of the spray tower 4 via a duct 3. A fan is connected to the air outlet of the spray tower 4. The self-cleaning filter assembly 5 includes an isolation cover 51 installed in the liquid storage tank of the spray tower 4. A filter cartridge 52 is installed on the inner side of the isolation cover 51. A slot flush with the inner wall of the filter cartridge 52 is opened on the side of the isolation cover 51. A rotating shaft 53 is rotatably installed in the filter cartridge 52, and the rotating shaft 53 is connected to a connecting rod 5. 4. A spiral plate 55 is connected to the inner wall of the filter cylinder 52. One end of the rotating shaft 53 rotates through the liquid storage tank of the spray tower 4 and is connected to the reduction motor 57 via a chain drive mechanism 56. The inlet of the circulating pump 41 in the spray tower 4 is connected to the cavity inside the isolation cover 51 through a pipe. Dust is removed from the discharge port of the funnel 1 by spraying. Impurities adsorbed in the water are effectively filtered by the filter cylinder 52. When the spiral plate 55 rotates under the drive of the reduction motor 57, it can effectively clean the impurities filtered on the inner wall of the filter cylinder 52, so that the filter cylinder 52 can filter for a long time. Two chain drives are installed on each rotating shaft 53. In mechanism 56, the sprockets and two adjacent rotating shafts 53 are connected by a set of chain drive mechanisms 56. Multiple sets of chain drive mechanisms 56 can stably transmit power to each rotating shaft 53. The spiral plate 55 has bristles adhered to the side facing the inner wall of the filter cartridge 52. When the spiral plate 55 rotates, the bristles brush the inner wall of the filter cartridge 52 and push the removed impurities to one side of the isolation cover 51. A collection trough 58 is formed between the side of the isolation cover 51 with the slot and the inner wall of the liquid storage tank of the spray tower 4. A slot flush with the inner wall of the collection trough 58 is opened on the liquid storage tank of the spray tower 4 at one end of the collection trough 58, and a blind cover is installed at the slot. The blind plate 59 is bolted to the spray tower 4. After the blind plate 59 is removed, the impurities accumulated in the collection tank 58 can be quickly discharged. The dust collection assembly 2 includes a flange pipe 21, which is bolted to the discharge port flange of the funnel 1. A dust collection groove 22 is welded to the outside of the flange pipe 21. The side of the dust collection groove 22 is connected to one end of the air duct 3. The dust overflowing from the discharge port of the funnel 1 can be guided by the dust collection groove 22 and sucked into the air duct 3. There are multiple connecting rods 54, and the two ends of the connecting rods 54 are respectively connected to the rotating shaft 53 and the spiral plate 55. Multiple connecting rods 54 can stably connect the rotating shaft 53 and the spiral plate 55.

[0022] The working principle of this technical solution is as follows: When the funnel 1 discharges material, the dust overflowing from the discharge port is guided into the air duct 3 by the dust suction trough 22, and enters the spray tower 4 with the airflow. In the spray tower 4, the dust comes into full contact with the spray water and is captured by the water to form dust-containing wastewater, which settles into the storage tank. The purified air is discharged by the fan after the water mist is removed by the demister at the top of the spray tower 4. The geared motor 57 runs continuously and drives all the rotating shafts 53 to rotate synchronously through the chain drive mechanism 56. When the spiral plate 55 rotates with the rotating shaft 53, the bristles on its surface brush the inner wall of the filter cartridge 52, pushing the impurities intercepted by the filter cartridge 52, such as mud, sand and metal oxide particles, along the spiral plate 55 into the collection tank 58 between the isolation cover 51 and the inner wall of the storage tank. When the impurities in the collection tank 58 accumulate to a certain amount, the machine is stopped and the blind plate 59 is removed. The impurities are discharged from the collection tank 58 by the water flow in the storage tank or by manual rinsing. After the slag is discharged, the blind plate 59 is reinstalled to ensure a seal.
