[0020] The specific implementation of the present utility model is described below with reference to the accompanying drawings.
[0021] As attached Figure 1 and Figure 2As shown, a dust removal device used in coated asphalt packaging includes a dust removal mechanism 2 connected to the discharge port 11 of a silo 1, the silo 1 is used to place the coated asphalt, and the dust removal mechanism 2 includes a connecting flange 21, an inner tube 23 and an outer tube 22, wherein the connecting flange 21 is connected to the discharge port 11, specifically, another connecting flange 21 is provided at the discharge port 11 of the silo 1. During installation, the two connecting flanges 21 are connected and fixed, so that the dust removal mechanism 2 can be fixed at the discharge port 11. At the same time, a discharge valve is provided in the discharge port 11, and the discharge valve can be a pneumatic discharge valve, which has the advantages of good sealing performance, high temperature resistance, strong wear resistance, flexible opening and closing, no dust jamming and dust accumulation, long service life, etc., and the pneumatic discharge valve is used to control the opening and closing of the discharge port 11 to complete the bagging of the coated asphalt.
[0022] As attached Figures 2 to 5 As shown, the bottom surface of the connecting flange 21 is provided with an inner tube 23 and an outer tube 22, and the inner tube 23 and the outer tube 22 are welded to the bottom surface of the connecting flange 21, and the outer tube 22 is sleeved on the outer side of the inner tube 23, wherein the inner tube 23 is connected with the discharge port 11, and the inner diameter of the outer tube 22 is larger than the outer diameter of the inner tube 23, so that there is a gap between the outer wall of the inner tube 23 and the inner wall of the outer tube 22, and the gap forms a dust removal chamber 2a, and the bottom cavity of the dust removal chamber 2a is open, and the outer surface of the outer tube 22 is provided with a suction pipe 25 The head end of the suction pipe 25 is connected to the dust removal chamber 2a, and the end of the suction pipe 25 is connected to the suction port of the dust removal fan. The working principle of the dust removal fan is that the motor drives the impeller to rotate at high speed, generating a strong negative pressure, so that the dirty gas enters the fan through the suction port. When the dust-containing gas moves in a spiral shape (that is, the airflow moves in a spiral shape along the inner wall of the body shell), it is in the shape of a hollow cone. The airflow in the center can flow to the boundary, and the airborne dust is separated by its strong centrifugal force to achieve the primary filtration of the dust-containing gas. When in use, the bag mouth 31 of the ton bag 3 is put on the outside of the outer tube 22 and fastened, and then the discharge valve in the discharge port 11 is opened. At this time, the coated asphalt in the silo 1 falls into the ton bag 3 for bagging. At the same time, the dust removal fan is turned on. At this time, the suction force of the dust removal fan recovers the dust generated during the bagging process through the dust removal chamber 2a and the suction pipe 25, avoiding dust pollution, protecting the health of employees, improving on-site hygiene, and recycling products. The inner tube 23, the outer tube 22 and the suction tube 25 are all made of stainless steel, and have the advantages of corrosion resistance, high strength, high temperature resistance and wear resistance.
[0023] In addition, as attached Figures 2 to 4 As shown, a filter screen 24 is provided at the bottom cavity opening of the dust removal chamber 2a, and the filter screen 24 can be used to filter the dust recovered through the dust removal chamber 2a and the suction pipe 25 to intercept large particles of asphalt that are accidentally rolled up, thereby reducing product losses on the one hand and reducing the risk of clogging of the suction pipe 25 on the other.
[0024] In addition, if attached Figure 3 and Figure 5 As shown, the outer surface of the outer tube 22 is provided with an inwardly concave fixing groove 2b, which is an annular structure, and the axis of the fixing groove 2b coincides with the axis of the outer tube 22. When in use, the bag opening 31 of the ton bag 3 is fastened in the fixing groove 2b by a rope, and the rope is embedded in the fixing groove 2b at this time. The limiting effect of the groove wall of the fixing groove 2b on the rope is used to prevent the rope from slipping off the outer tube 22 under force during bagging, causing the ton bag 3 to detach from the outer tube 22 and the coated asphalt to spill all over the ground. After the bag opening 31 of the ton bag 3 is fastened to the outer tube 22, when bagging, not only can both hands be freed, and there is no need to manually pull the bag opening 31 of the ton bag 3, but also the gap between the outer wall of the outer tube 22 and the bag opening 31 of the ton bag 3 can be reduced, so as to prevent the coated asphalt dust from leaking out from the gap between the outer tube 22 and the ton bag 3.
[0025] In summary, when the utility model is in use, the bag mouth 31 of the ton bag 3 is put on the outside of the outer tube 22 and tied up. On the one hand, both hands are freed and there is no need to manually pull the bag mouth 31 of the ton bag 3. On the other hand, the gap between the outer wall of the outer tube 22 and the bag mouth 31 of the ton bag 3 can be reduced to prevent the coated asphalt dust from leaking out from the gap connecting the outer tube 22 and the ton bag 3. Then, the discharge valve in the discharge port 11 is opened. At this time, the coated asphalt in the silo 1 falls into the ton bag 3 for bagging. At the same time, the dust removal fan is turned on. At this time, the suction force of the dust removal fan recovers the dust generated during the bagging process through the dust removal chamber 2a and the suction pipe 25, thereby avoiding dust pollution, protecting the health of employees, improving on-site hygiene, and recycling products.
[0026] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
