Detailed Description
The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
Example (b): as shown in the attached drawings 1-8, the dust removing device for cement production comprises a rotary box body unit 1, two sections of exhaust pipes a are respectively inserted into two sides of the rotary box body unit 1, a filter screen cloth 2 is arranged in the rotary box body unit 1 and used for intercepting dust in air, a water body 3 is arranged in the rotary box body unit 1 and used for soaking the filter screen cloth 2 and temporarily storing the dust, and a radial guide plate unit 4 is arranged on the inner side surface of the rotary box body unit 1 and used for watering the filter screen cloth 2.
In this embodiment, install the roof opening at the breaker in suction hood b, or directly on the feed inlet, then open air exhauster c, can filter screen cloth 2 is last to hold back the dust, guarantees the most basic dust removal effect.
The rotary box body unit 1 is used for forming a relatively closed cavity for the filter screen cloth 2, so that air with dust can completely pass through the filter screen cloth 2 to the maximum extent.
In addition, the water body 3 is ordinary tap water, and has two functions:
firstly, soaking the filter screen cloth 2 to enable water drops to be attached to filter screen holes with relatively large apertures so as to increase the efficiency of adsorbing and intercepting fine dust, namely, compared with a filter screen with large apertures without water, the filter screen has a larger dust interception rate, and compared with a filter screen with small apertures without water, the filter screen has a larger air flow rate;
secondly, the water 3 can wash off all the dust trapped on the filter screen cloth 2, so as to ensure that the meshes of the filter screen cloth 2 are continuously unblocked, and greatly prolong the cleaning period of the filter screen, for example, the cleaning period of the filter screen with the same aperture is 1-2 days, whereas in the present embodiment, under the same working condition of dust removal, the cleaning period can be prolonged to 5-8 days until the water 3 becomes turbid 'muddy water'.
Finally, because the addition of water 3 can not submerge wholly filter screen cloth 2, consequently filter screen cloth 2 has partial region can not hit water, can not be soaked, consequently introduces radial guide plate unit 4 makes originally dry filter screen cloth 2 intermediate position also can be watered and soaked, guarantees wholly filter screen cloth 2 all has moist filterable result of use.
The rotary box body unit 1 comprises a circular box body 101 and two central holes 102 which are respectively arranged on the planes of the two box bodies and used for inserting the exhaust pipe a, the circular edge of the circular filter screen cloth 2 is arranged on the inner annular surface of the circular box body 101, and the liquid level of the water body 3 is lower than the lowest point of the central holes 102.
In this embodiment, the amount of the water 3 added in the circular box 101 cannot be too large for two reasons:
firstly, the more the water body 3 is, the larger the area of the lower minor arc arch-shaped area where the filter screen cloth 2 is immersed all the time, and the area of the area is an ineffective area for filtering and removing dust, so that the water body 3 cannot be too much;
secondly, if the water 3 is too much, the water will flow out from the central hole 102, and the water 3 is already sewage containing silt.
In addition, in the use process of the dust removing device, the circular box 101 continuously rotates, so that the effective immersion wetting parts of the filter screen cloth 2 are alternately updated all the time, that is, at least one circle of annular area outside the filter screen cloth 2 is an effective immersion wetting area.
Finally, the circular box body 101 rotates together with the radial guide plate unit 4, so that the water body 3 on the radial guide plate unit 4 has a potential energy which flows downwards and waters the filter screen cloth 2, the middle part of the filter screen cloth 2 can be moistened again, and finally almost the whole filter screen cloth 2 can be moistened fully and properly.
The radial guide plate unit 4 comprises radial plates 401 which are arranged on the inner annular surface of the circular box body 101 and are respectively positioned at two sides of the filter screen cloth 2.
In this embodiment, the radial plate 401 rotates along with the circular box 101, so that the water 3 at the front end side in the rotation direction is "lifted up" by the radial plate 401, and then the radial plate 401 rotates to be nearly horizontal, and then the water 3 is thrown down and flows down to be watered to the filter screen cloth 2, so that the central part of the filter screen cloth 2, which is originally dry, can be wetted for use.
The side edge of the radial plate 401, which is far away from the filter screen cloth 2, and the inner side plane of the circular box body 101 are fixedly connected into a whole without a gap, so that the water body lifted up on the radial plate 401 is guaranteed to be completely poured onto the filter screen cloth 2.
The radial inner end of the radial plate 401 is inclined toward the front end of the rotation direction of the circular box 101.
In this embodiment, it is assumed that the radial plate 401 and the aligned radial plate d need to have the same inclination angle when watering is started downwards, as shown by the two dotted line positions in fig. 5, so that it is obvious that the preferred radial plate 401 has a higher downward watering height than the aligned radial plate d, so that the watering is further and wider, and the filter screen cloth 2 can be soaked quickly and maximally, which can greatly improve the efficiency of the filter screen cloth 2 in soaking and removing dust.
The included angle formed between the radial plate 401 and the filter screen cloth 2 and located at the front end of the circular box 101 in the rotating direction is an acute angle.
In this embodiment, the acute angle setting is the same as the above-mentioned radial board 401 with the effect that the inboard plane of circular box body 101 is connected and thus does not leave the gap, is exactly to guarantee radial board 401 "lifts up" part the water 3 can all be poured on filter screen cloth 2, guarantees that filter screen cloth 2 has the dust removal effect of wetting of more efficient.
The radial baffle unit 4 further includes water leakage holes 402 provided on the radial plate 401 at positions close to the radially inner ends.
In this embodiment, the radial plates 401 are used for watering and wetting the central portion of the filter screen cloth 2, and a circle of circular ring-shaped portion outside the filter screen cloth 2 can be directly immersed in the water 3, which can also ensure the wetting, but how large the area of the central portion to be watered is depends on many factors such as the area of the filter screen cloth 2, the water amount of the water 3, the number of the radial plates 401, the rotation speed of the circular box 101, and the flowing ability of water on the filter screen cloth 2, and thus is difficult to be accurately controlled.
Therefore, a dry part, namely a middle area, may still exist between the central wet part and the side circle of wet parts, so that the water leakage holes 402 are arranged, the water part which is originally lifted up by the radial plates 401 flows downwards to the middle area, and finally the whole filter screen cloth 2 can be soaked as far as possible.
The radial baffle unit 4 further comprises an arc plate 403 arranged at the radial outer end of the radial plate 401 and used for pressing and fixing the filter screen cloth 2. The central angle of the arc plate 403 ranges from 30 to 90 °.
In this embodiment, the action of the arc plate 403 has two functions: first, it is the mounting base of the radial plate 401; secondly, be the filter screen cloth 2 compresses tightly the installation position, consequently set up on the arc 403 and connect the screw of the interior anchor ring of circular box body 101 can guarantee that filter screen cloth 2, radial guide plate unit 4 can both stably install.
In addition, in this embodiment, 4 pairs of radial plates 401 are arranged, and the two sides of the filter screen cloth 2 are arranged in rows, so that the central angle of the arc plate 403 is 90 °, and the filter screen cloth 2 can be pressed for a whole circle.
Of course, if the radial plates 401 are changed to 6 pairs, the central angle of the arc plates 403 is 60 °.
The rotary cassette unit 1 further includes a driving toothed belt 103 provided on an outer circumferential surface of the circular cassette 101.
In this embodiment, an annular groove for engaging and fixing the driving toothed belt 103 is formed on an outer circumferential surface of the circular box 101, and the driving toothed belt 103 engages with a motor gear to ensure that the circular box 101 stably and controllably rotates.
The rotation speed is critical, and can be adjusted according to the flowing and throwing conditions of the water body 3 on the radial deflector unit 4, and the final purpose of the rotation speed adjustment is to increase the wetted area of the filter screen cloth 2 by the water body 3.
The rotary cartridge unit 1 further comprises bristles 104 disposed on the annular face of the central aperture 102.
In this embodiment, the gap between the central hole 102 and the exhaust pipe a is harmful, which reduces the amount of dust-proof air passing through the filter screen cloth 2, but if the central hole 102 is provided with a sealing rubber ring, the rotation of the rotary box body unit 1 has a large resistance, so the bristles 104 are provided in this embodiment, and by means of a compromise, a large sealing effect is ensured, and the rotation resistance of the rotary box body unit 1 is not significantly increased.
The bristles 104 are made of common plastic wires, one end of each bristle is bonded and fixed to the annular surface of the central hole 102, and the other end of each bristle abuts against the outer annular surface of the exhaust pipe a.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications that fall within the scope of the claims of the present invention, which are protected by the patent statutes.
