Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

The embodiment of the present utility model relates to an integral cyclone filter dust remover, as shown in Figure 1, comprising an intake pipe 1, a swirl section exhaust pipe 2, a filter bag 3, an intercepting section exhaust pipe 4, and a cylinder 5, Cone 6, ash hopper 7 and perforated disc 9, a cylindrical iron frame is placed in the filter bag 3 to keep the filter bag 3 in a cylindrical shape; the filter bag 3 is stuck in the perforated disc on the disc 9; the perforated disc 9 is connected to the cylinder 5 by a flange, and a gasket 8 is arranged in the middle, and is fixed with bolts 10; the cylinder 5 is connected to the cone 6; The cone 6 is connected to the ash hopper 7; the air intake pipe 1 is below the filter bag 3 and connected tangentially to the cylinder 5; the swirl section exhaust pipe 2 There is a 15-degree slope at the top cover, and it is connected to the cylinder 5 below the filter bag 3; the interception section exhaust pipe 4 is above the filter bag 3 and connected to the cylinder Body 5 is connected. Its working principle is roughly as follows: when the burst dust generated by the dust source enters the intake pipe 1, due to the tangential connection between the intake pipe 1 and the cylinder 5, the dust-laden airflow tangentially enters the cylinder 5 and rotates, so that the separated dust particles Falling into the ash hopper 7 and being collected, the uncaptured fine dust particles rise to the exhaust pipe 2 of the swirl section along with the internal swirl flow, and the dust-laden gas coming out of the exhaust pipe 2 of the swirl section meets the filter bag 3 At this time, most of the fine dust particles are intercepted, and the clean gas passing through the filter bag 3 is discharged from the exhaust pipe 4 of the interception section, thereby completing the dust removal task of the dusty airflow.

The utility model is specifically described below by two embodiments.

Embodiment 1: The dust removal principle of the utility model is shown in FIG. 2 . The bracket 11 is used to support the entire cyclone filter dust collector housing. When the dust removal work is running, the self-control cabinet controls the recoil cleaning valves 12 and 15 to close, and the recoil cleaning valves 13 and 14 are opened. Paroxysmal dust generated by the dust source enters the intake pipe 1, and the motor 18 drives the fan 17 to rotate, so that the dust-laden airflow is sucked into the cylinder 5 tangentially, and a centrifugal force is generated during the rotation, and the large particles are thrown to the cylinder wall due to the centrifugal force. Fall along the cylinder wall and enter the ash hopper 7 to collect; when the rotating airflow reaches a certain position at the lower end of the cone 6, it reverses from the middle of the cyclone filter dust collector in the same direction of rotation from bottom to top, and continues to flow in a spiral shape, forming Internal swirling air flow, the swirling air flow at this time is primary purification gas. The primary purified gas rises through the exhaust pipe 2 of the swirl section, and a part of the uncaptured fine particles also rises to the interception section through the internal swirl flow. When it hits the filter bag 3, most of the fine particles are captured. The air flow at this time is Secondary purification gas. The secondary purified gas is discharged through the exhaust pipe 4 of the interception section, and a very small number of fine particles penetrate the filter bag 3 and escape from the exhaust pipe 4 of the interception section on the side. The utility model adopts intermittent operation, adopts reverse blowing airflow when cleaning dust, and the motor drives the fan to rotate. Fall into the ash hopper along the slope of 15 degrees to catch it.

Embodiment 2: As shown in Figure 3, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the outlet of the clean gas is vertically upward, and the outlet is connected to the cylinder of the intercepting filter section by a circular reducer. This structure makes the dust-laden airflow flow evenly without air flow dead angle, and is suitable for places where the height of the air duct connection is allowed to be high. In this embodiment, four filter bags are set, and the air step ratio is 14m/min. The test results show that: when the inlet velocity is 15m/s, the filtration wind velocity is 0.236m/s, the pressure loss is 1043Pa, the total collection efficiency is 95%, which is 10% higher than the original cyclone dust collector, and the pressure loss only increases Less than 20%. If more filter bags are added to increase the filter area, the pressure loss can be reduced to less than 1000Pa. This proves that the utility model has high dust collection efficiency and moderate pressure loss, which is only less than 20% higher than that of ordinary cyclone dust collectors.
