Technical Field

The utility model relates to a dust collection field, concretely relates to exit dust cage of horizontal circle feed cylinder.

Background

Dust generally refers to solid particles that can be suspended in air for a longer period of time. The dust is an aerosol, and the solid tiny dust particles are actually distributed in the solid dispersion medium taking air as a colloidal solution.

The dust collecting hood is one device for controlling dust flow and collecting dust and is one important part of local ventilating dust collecting system. The dust collecting hood is used for collecting dust emitted by a dust source and guiding the dust into the purification system so as to prevent the dust from diffusing to a production workshop and the atmosphere to cause pollution. If the form and the position are reasonably selected, a good dust removal effect can be obtained.

The existing dust hood has the defects that the suction force at the position of the air suction hood is often insufficient along with the increase of the diameter of the circular charging barrel, so that the flue gas is not uniformly absorbed around or at a place far away from an air suction opening, and the flue gas cannot be absorbed. And because the diameter of the round charging barrel is increased, the problems of leakage and the like are easy to occur when the dust hood is connected with the round charging barrel, so that the dust hood with good air suction effect and good sealing property is needed.

Detailed Description

The present application will now be described in further detail with reference to the drawings, and it should be noted that the following detailed description is given for purposes of illustration only and should not be construed as limiting the scope of the present application, as these numerous insubstantial modifications and variations can be made by those skilled in the art based on the teachings of the present application.

Examples

As shown in figure 1, the dust cage for the inlet and the outlet of the horizontal round charging barrel is sleeved on a horizontal round charging barrel 10. The dust hood comprises an air suction hood 1, a dust hood 2 and an air leakage prevention structure 3, wherein the air suction hood 1 is arranged on the dust hood 2 and communicated with the inside of the dust hood, and the air suction hood 2 is used for providing suction force when smoke is sucked; the air leakage prevention structure 3 is arranged at one end of the dust hood 2, can be tightly connected with various horizontal round charging barrels, and can prevent air leakage and the like.

Dust absorption cover 2 comprises dustcoat 21, inner cover 22, and inner cover 22 sets up inside dustcoat 21, separates into interlayer one 211, interlayer two 212 with dustcoat 21, and the spaced apart diaphragm orifice that is equipped with on the inner cover 22, interlayer one 211, interlayer two 212 of diaphragm orifice intercommunication at first collects the flue gas by interlayer one 211, and the flue gas of interlayer one kind is evenly absorbed through the diaphragm orifice of equidimension not to rethread interlayer two 212 to realize the evenly distributed of amount of wind. The raised dust or smoke generated in the production of the cylinder is collected by the outer cover 21 of the dust collection cover, passes through the plate holes arranged on the inner cover 22, enters the second interlayer 212 and finally is collected in the air suction cover 1. Because the inner cover 22 is in a bilateral symmetry structure, the plate holes formed on the inner cover 22 are also in bilateral symmetry and are distributed in the dust hood 2 in a surrounding manner. As shown in fig. 2, the plate holes of the inner cover 22 of the present embodiment can be divided into a first plate hole 221, a second plate hole 222, a third plate hole 223, and a fourth plate hole 224, and the first plate hole 221, the second plate hole 222, the third plate hole 223, and the fourth plate hole 224 are sequentially away from the inlet of the air suction cover 1. Because the farther the inlet of the air suction cover 1 is, the smaller the suction force at the plate hole position is, the farther the inlet of the air suction cover 1 is, the larger the diameter of the plate hole is, and the uniform distribution of the air quantity of each plate hole can be effectively ensured.

As shown in fig. 3, the air leakage preventing structure 3 includes an outer fixing ring 31 and an inflatable liner ring 32, wherein a leakage preventing groove 311 is formed on an inner side surface of the outer fixing ring 31, the inflatable liner ring 32 is installed in the leakage preventing groove 311, an inflation inlet of the inflatable liner ring 32 is formed on an outer surface of the outer fixing ring 31, and the inflation inlet is connected with the inflatable liner ring 32 through an air pipe. When the dust collecting cover is used, after the dust collecting cover is sleeved on the horizontal round charging barrel, the inflatable inner container ring 32 is inflated through the inflation inlet, the inflatable inner container ring 32 swells and slowly fills the leakage-proof groove 311, and after the inflatable inner container ring is filled with air, the inflatable inner container ring 32 can swell outwards and closely contact with the outer surface of the horizontal round charging barrel due to continuous inflation, so that sealing and leakage prevention are realized. Through setting up leak protection gas structure 3, not only simple structure has effectively reduced the cost of administering the gas leakage, and the leak protection is effectual, dismantles the convenience. In order to monitor the leakage-proof effect in real time, a pressure monitoring system can be arranged in the inflatable liner ring 32, and when the air pressure is lower than a set value, an external inflating device can automatically inflate the inflatable liner ring 32. And through setting up the leak protection gas structure 3 of inflatable, the dust cage can be applicable to the horizontal round feed cylinder of more different diameters, has the advantage that application scope is wide.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
