Detailed Description
As shown in fig. 1, a first embodiment of the present invention includes a settling system and a continuous impurity discharging system connected to a lower end of the settling system and continuously discharging settled light impurities and dust.
The sedimentation system comprises a sedimentation tank 1, two partition boards 4 used for dividing the inner cavity of the sedimentation tank 1 into a first sedimentation chamber 2 and a second sedimentation chamber 3 are arranged in the sedimentation tank 1 at intervals, an air channel 5 used for communicating the bottom of the first sedimentation chamber 2 and the top of the second sedimentation chamber 3 is formed between the two partition boards 4, a sundry inlet 6 is arranged at the top of the first sedimentation chamber 2 on the side wall of the sedimentation tank 1, an exhaust opening 7 is arranged at the top of the second sedimentation chamber 3 on the top wall of the sedimentation tank 1, and an air outlet is connected to a negative pressure fan through an air pipe.
In the implementation process, air carrying light impurities and dust is sucked into the first settling chamber 2 through the impurity inlet 6, most of the light impurities and dust settle down due to the reduction of the air flow speed, and a very small amount of dust entering the second settling chamber 3 along with the air drops down due to the further reduction of the air speed. The side wall of the bottom of the sedimentation tank 1 is adduction to form an inclined plane for assisting dust and impurities to slide from the sedimentation tank 1 to the impurity collecting tank 8, and a chamfer for facilitating the dust and impurities to enter the first sedimentation chamber 2 is arranged below the connecting part of the impurity inlet 6 and the sedimentation tank 1, so that light impurities and dust are not easy to accumulate on the inner wall of the sedimentation tank 1 and the positions of the sedimentation tank 1 and the impurity inlet 6. The air suction opening 7 is arranged on the top wall of the sedimentation tank 1 and is positioned at the top part of the second sedimentation chamber 3 and far away from the ventilating duct 5, so that light impurities and dust which are introduced into the second sedimentation chamber 3 through the ventilating duct 5 are prevented from being sucked into the negative pressure fan after sedimentation.
The continuous impurity removal system comprises an impurity collection box 8 which is communicated with the bottoms of the first settling chamber 2 and the second settling chamber 3 and is used for collecting settled light impurities and dust, and the impurity collection box 8 in the embodiment is of a long cylinder shape corresponding to the width of the bottom surface of the settling box 1, and the cross section of the impurity collection box 8 is of a circular arc shape. The impurity collecting box 8 is provided with a rotating shaft 9 along the length direction, and two ends of the rotating shaft 9 are respectively and rotatably arranged at the central positions of two ends of the impurity collecting box 8. The rotating shaft 9 is provided with a plurality of blades 11 at intervals, the blades 11 are used for discharging dust and impurities in the impurity collecting box 8 from the impurity discharging port 10 connected to the lower end of the impurity collecting box 8 through the rotation of the rotating shaft 9, the blades 11 are all arranged along the length direction of the rotating shaft 9, and the limiting gap between the outer edge of each blade 11 and the circular arc inner wall of the impurity collecting box 8 and the bottom of the second partition plate 402 is smaller than 2 mm. The variable frequency motor is arranged outside the impurity collecting box 8 to drive the rotating shaft 9 to rotate, and then the light impurities and dust in the impurity collecting box 8 are discharged through the impurity discharging port 10 by the rotation of the blades 11, so that clean air after impurity removal is pumped out from the air suction port 7, and the effect of dust removal and impurity removal is achieved. The variable frequency motor can be flexibly adjusted according to the light impurity and dust concentration in the environment and the speed of accumulating sediments in the impurity collecting box 8.
As shown in fig. 2, a second embodiment of the present invention is different from the first embodiment in that:
1. the width of the first settling chamber 2 and the width of the second settling chamber 3 are gradually increased from top to bottom, and the ventilating duct 5 has a structure with a wide bottom and a narrow top. The width of the first settling chamber 2, the second settling chamber 3, and the air passage 5 is tapered by the shape and the arrangement angle of the first partition 401 located on the first settling chamber 2 side and the second partition 402 located on the second settling chamber 3 side. The first baffle 401 is V-shaped, the top and two sides of the first baffle are in sealing connection with the inner wall of the sedimentation tank 1, the second baffle 402 is a single plate, two sides of the second baffle are in sealing connection with the inner wall of the sedimentation tank 1, and the bottom is close to the continuous impurity removal system. The arrangement mode can obviously reduce the flow velocity of dust-carrying air at the bottoms of the two settling chambers, thereby being beneficial to the settlement of light impurities and dust, and being difficult to lead the dust-carrying air in the first settling chamber 2 to carry excessive light impurities and dust to enter the second settling chamber 3 through the ventilating duct 5, and greatly improving the impurity removal efficiency of the invention.
2. A guide plate 12 for guiding the dust-containing air flow introduced into the second settling chamber 3 from the air duct 5 toward the bottom of the second settling chamber 3 is provided at the top of the second settling chamber 3. The guide plate 12 is a spiral plate which is connected to the inner wall of the second settling chamber 3 and the second partition plate 402 in a sealing way, and the initial end of the spiral plate is positioned at the top of the communication port between the ventilating duct 5 and the second settling chamber 3. The arrangement mode can be matched with a structure with a wide lower part and a narrow upper part of the ventilating duct 5, so that air with a small amount of dust enters the second settling chamber 3 at a high speed, is sprayed to the bottom of the second settling chamber 3 under the guiding action of the guide plate 12, and can be efficiently settled due to the gradient structure of the width of the second settling chamber 3 in the process, the dust can be discharged through the continuous impurity removing system, and clean air after dust removal and impurity removal is pumped out through the exhaust opening 7.
