Abstract

The utility model discloses a dual-layer automatic dust hood for a conveyor belt, comprising a bracket; a dual-layer closed cover unit body is connected on the bracket; an ash remover is arranged on the dual-layer closed cover unit body; the dual-layer automatic dust hood at least comprises two dual-layer closed cover unit bodies that are spliced with each other; and one end or two ends of each dual-layer closed cover unit body are provided with dust retaining curtains. When the dual-layer automatic dust hood is used, the dusts generate swirling eddy in the dual-layer closed cover unit body so that the larger dust grains are freely deposited on the belt; the ash remover adopts a suction pipe which can effectively adsorb the dusts on the internal layer and the external layer of the dual-layer closed cover unit bodies; the dual-layer automatic dust hood has a reasonable and simple structure and can be assembled conveniently.

Description

Belt conveyor is with double-deck automatic dust absorption cover

Technical field

The utility model belongs to device for transporting objects, is specifically related to the double-deck automatic dust absorption cover on a kind of particulate dust belt conveyor.

Background technology

Individual layer enclosed hood top adopts plumbing system to insert dusting equipment usually, because plumbing system is oversize, resistance can increase (new 1200pa, old 2000pa) pipeline post precipitation and can stop up after the dust exhaustor long-time running, and the later stage dust removing effects can be very poor.

Perhaps the dress minitype high voltage pulse bag-type dust-removing equipment at individual layer enclosed hood top because of adopting high-pressure pulse deashing and vertically dust being dropped on the belt conveyor, need be taked water spray and high filtering wind speed blower fan for preventing this dusting equipment of reentrainment of dust; Usually be (2.1-4.0m/min) in dust-precipitator inner blower filtration velocity value; Operation under this wind speed for a long time, less dust granule has stronger penetrance, permanent the resting in the filter bag gap of meeting; Deashing is not thorough; The dust-precipitator resistance can significantly rise after using a period of time, and the later stage dust-precipitator often in " free work ", do not take away by setting post dust.Also need compressed air line and water source (the low water pipe meeting of temperature in winter bursting by freezing, later period maintenance and effect can be very poor) in this equipment operation, long-time running is very uneconomical.Existing double-deck enclosed hood, but owing to have the enclosed hood of double-layer structure, the dusting equipment of its upper end is poor for the dust assimilation effect of internal layer, and operating cost is high.

Summary of the invention

The purpose of the utility model is to provide a kind of belt conveyor with double-deck automatic dust absorption cover, to address the above problem.

The technical scheme of the utility model is: belt conveyor is with double-deck automatic dust absorption cover; It comprises support; Bonded assembly double-layer seal cover cell cube on the support; Establish ash cleaning and dust removing device on the double-layer seal cover cell cube, which comprises at least two amalgamation bonded assembly double-layer seal cover cell cubes and constitute, an end or the both ends of each double-layer seal cover cell cube are provided with the dust-break curtain.

Ash cleaning and dust removing device has two dust suction mouths of pipe, and a dust suction mouth of pipe extend into the internal layer of double-layer seal cover cell cube, and another dust suction mouth of pipe extend into the skin of double-layer seal cover cell cube.

Said ash cleaning and dust removing device comprises housing; Cloth bag is set in the housing, and connection ash bucket under the housing connects UNICOM's sweep-up pipe on ash bucket one side; Sweep-up pipe extend into the internal layer of double-layer seal cover cell cube, offers suction port on the opposite side of ash bucket and communicates with the skin of double-layer seal cover cell cube.

The utility model adopts the double-layer seal cover cell cube of split type; End in each double-layer seal cover cell cube is provided with the dust-break curtain; Dust can produce swirling eddy, make bigger dust granules free setting to belt in double-layer seal cover cell cube; Ash cleaning and dust removing device adopts sweep-up pipe, and a sweep-up pipe extend into the internal layer of double-layer seal cover cell cube, and another sweep-up pipe extend into the skin of double-layer seal cover cell cube; The airborne dust of adsorption treatment double-layer seal cover cell cube ectonexine effectively; Blower fan adopts the tangible variable-frequency motor of energy-saving effect, can regulate air quantity according to the size (the explosive diffusion size of dust) of material drop malleation, and absolute advantage is arranged in economical operation.It is rational in infrastructure simple, easy for installation.

The specific embodiment

As shown in Figure 1, support 100 is provided with the double-layer seal cover that four double-layer seal cover cell cubes 200 are formed by connecting, and one of them double-layer seal cover cell cube is provided with clearly.Support 100 is located at the both sides (as shown in Figure 2) of belt conveyor 400.

As shown in Figure 4, double-layer seal cover cell cube 200 comprises outer cover 201, is connected with inner cover 202 in the outer cover 201; Be connected with inner cover sealing band 203 on the inner cover 202; 201 times both sides of outer cover are provided with interior plate 204 respectively, and the medial surface of interior plate 204 matches with the medial surface of two support beams respectively and contacts, and form the inversed taper platform sealing surface, are connected with outer cover sealing band 205 on the interior plate 204.Can be that to be welded to connect also can be through bolted connection between outer cover 201 and the inner cover 202.

Like Fig. 1, shown in 4; One end of double-layer seal cover cell cube is provided with dust-break curtain 206; In the present embodiment; Dust-break curtain 206 is connected the end of inner cover 202, and the dust-break curtain 206 of each double-layer seal cover cell cube upper end all is arranged on the left side of double-layer seal cover cell cube, also is provided with dust-break curtain 206 in the right-hand end of double-layer seal cover cell cube 200.4 of a joint of low order end;

As shown in Figure 1; Ash cleaning and dust removing device 300 is located on the 3rd joint double-layer seal cover cell cube 200.3, and ash cleaning and dust removing device 300 can adopt fiber bag precipitator, like Fig. 2, shown in 5; Ash cleaning and dust removing device 300 comprises bracing frame 301; Establish housing 302 on the bracing frame 301, cloth bag 303 is set in the housing 302,302 times connection ash buckets 304 of housing; Ash bucket 304 1 sides offer suction port 305, and suction port 305 links with the skin of double-layer seal cover cell cube 200, and (as shown in Figure 4) promptly communicates with the chamber 207 of outer cover 201.Ash bucket 304 opposite sides offer sweep-up pipe 306, and sweep-up pipe 306 extend into the internal layer of double-layer seal cover cell cube 200, promptly extend into the chamber 208 interior (like Fig. 1,2) of inner cover 202.
