Drawings
Fig. 1 is the structural schematic diagram of an embodiment of the dust treatment device at the feeding end of the waterproof roll production line of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model discloses a waterproofing membrane production line feed end dust treatment device's concrete structure is shown in figure 1, including box 1, delivery pipe 2 and circulation processing pipe 3. Wherein the discharge pipe 2 is used for guiding the powder-containing air flow at the tail end of the feeding pipe, the box body 1 is filled with water, and the lower end of the discharge pipe 2 extends below the liquid level, so that the powder-containing air flow discharged along the discharge pipe 2 can be washed by the water. The discharge pipe 2 may be composed of a feeding pipe, or may be an additional pipe connected to the lower end of the feeding pipe.
A baffle 7 is arranged in the box body 1, and the baffle 7 is positioned above the water surface. The baffles 7 are respectively disposed at both sides of the discharge pipe 2, and the baffle located at the left side of the discharge pipe 2 is a left baffle 71, and the baffle located at the right side of the discharge pipe 2 is a right baffle 72. The left and right baffles 71 and 72 are inclined downwardly near the end of the discharge pipe 2. The advantages of this structural arrangement are: in the process that the airflow containing powder transported along the discharge pipe 2 is washed by water, water in the box body 1 can be splashed upwards under the action of the airflow, and the water flow impulse is maximum at the periphery of the discharge pipe 2. The baffle 7 is inclined downwards near the discharge pipe 2, so that the water flow sprayed upwards around the discharge pipe 2 is firstly blocked by the baffle 7 right above, and the blocked water flow can move towards the end far away from the discharge pipe 2 along the baffle 7 to play a certain buffering role. The baffle 7 is prevented from being damaged by too large impact at the connecting and fixing part of the box body 1.
In this embodiment, the inclination angle of the baffle 7 is preferably 10 to 15 degrees.
In other embodiments, the baffle 7 may be hinged to the inner wall of the box 1, and a damping structure may be provided at the hinge, so that the baffle 7 may rotate around the hinge within a small range under the impact of water flow, and may return to its original position after the external force is removed, so as to further prevent the connection and fixation of the baffle 7 and the box 1 from being damaged by excessive impact. Wherein the damping structure may be a spring or a torsion spring installed between the baffle 7 and the cabinet 1.
The lower end of the circular processing pipe 3 extends into the water surface. A water pump 5 for pumping water in the box body 1 upwards is connected in series on the circulating processing pipe 3, three spraying pipes 6 are arranged at different height positions on the circulating processing pipe 3, and the tail ends of the spraying pipes 6 are communicated with the inner cavity of the vertically arranged pipe section of the discharge pipe 2 to form a spraying opening 8. Three of the spray ports 8 are arranged at intervals up and down along the vertically arranged pipe section of the discharge pipe 2, so that water flow sprayed out of the spray ports 8 can wash all powder-containing air flow below the spray ports, and the spray efficiency is extremely high. The water flow delivered by the water pump 5 flows out through the spraying opening 8, and the powder-containing air flow flowing in the discharge pipe 2 is washed from the side surface, so that the separation of the powder and the air flow is promoted. In a more preferred embodiment, in order to enhance the spraying effect, a spray head which can reduce the water flow area and increase the water pressure can be arranged at the spraying opening 8.
Therefore, when the powder-containing air flow flows from top to bottom in the discharge pipe 2, the powder-containing air flow is sprayed by the water flows in the three spraying ports 8 in sequence, part of the powder sinks into the water flow, and the rest of the powder is wetted by the water. When the airflow containing the powder is discharged from the lower end of the discharge pipe 2, the airflow can move upwards, and the wetted powder is easier to sink into the water contained in the box body 1. The air flow from which the powder has been removed continues to travel upwards and can be discharged from above the tank 1.
In other embodiments, the recycle treatment pipe 3 can also introduce spray water from outside the tank 1, but this design wastes a lot of water resources.
In this embodiment, the lower end surface of the circulation treatment pipe 3 is disposed higher than the lower end surface of the discharge pipe 2, so that the water introduced into the shower pipe 6 and the shower port 8 is water containing a small amount of powder in the upper layer of the tank 1.
It will be appreciated that the number of showers 6 is required to be flexibly adjusted to the overall size of the device. In other embodiments, the number of showers 6 can be more or less than three.
In other embodiments, the discharge pipe 2 may also include a horizontal pipe section or an inclined pipe section, and in this case, the spray ports may also be disposed on the corresponding pipe sections; it is also possible to arrange the discharge pipe 2 along one side of the tank 1, in which case it is only necessary to provide said baffle on one side of the discharge pipe 2.
In a more preferred embodiment, a vibrating precipitator 4 is connected in series in the discharge pipe 2, wherein the vibrating precipitator 4 is arranged above the shower opening 8 and has the function of removing a portion of the powder in advance before the powder-containing gas stream is washed with water. The structure of the vibrating dust collector 4 belongs to the prior art and is not described in detail in this application.
Finally, the description is as follows: the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
