Description

Dust collection device using aerodynamics {AERODYNAMIC DUST COLLECTING APPARATUS}

The present invention relates to a dust collection device using aerodynamics.

In general, dust collectors are equipment for separating dust by inertia of dispersed dust particles based on grill elements, which also include a device for discharging the separated dust material together with the inlet and outlet pipes.

Other known devices also use conical shapes in the form of ring systems to enhance dust removal.

There are grill elements that allow direct contact with the separated particles, and equipment with vortices in the boundary area is not very effective at separating dust.

In the second case, dust removal can be efficiently performed by introducing a ring that converges to the smallest diameter with a special conical shape. However, when there is a high humidity in the separated dust, or oil or light suspended solids, there may be a problem that the dust layer adheres to the hard components of the dust separation equipment. In this case, the need arises to carry out a survey and cleanup of the above components without stopping the technical process (operation). In addition, the known prototypes (swatches) have problems such as dust settling problems in the hopper, prevention of secondary bleeding from the hopper, and separation of contaminated gas flows and dust particle material separated in continuous operation. It does not provide a technical decision to solve the problem.

The present invention is to solve the above problems, the technical problem of the present invention is to provide a dust collection device using aerodynamics that can continuously perform the dust purification function without interrupting the operation of the dust collection device.

The dust separation module 1 and the dust precipitation hopper 2 are connected to each other by a dust inlet pipe 4.

Functionally, the aerodynamic dust separation module 1 separates dust particles from the overall dust gas flow. At this time, the overall dust gas flow is the incoming velocity V _BX and the outgoing velocity VB _bIX . The mechanism for separating the dispersed particles is streamlined with aerodynamics approved pairs forming the conical converging periodic ring or plate system together with the side outlets of the flow. In the hopper (2) at the outlet of the aerodynamic dust separation module (1), the separated and concentrated particle flow enters the hopper cavity through one of the pipes 5 to 8, which is then laid down by gravity and accumulated.

The slate 15 is mounted to observe the height of the dust accumulated in the inspection window 14.

The second lock 16 is operated automatically or semi-automatically to accumulate dust from the dust settling hopper 2.

As shown in FIG. 2, the dust separation module 1 may be mounted obliquely at an angle with respect to the vertical.

By arranging the first, second, third and fourth introduction pipes 5, 6, 7, and 8 in various ways, it is possible to facilitate the arrangement of various components of the aerodynamic dust separation module with respect to the hopper 2, and the dust separation module. At least three modules can be arranged in (1). This method can be used for the most sensitive element placement for pressure measurement instruments inside the dust settling hopper (2).

The structural features of the dust settling hopper 2 are shown in FIG. 3. In addition to the member elements shown in Figs. 1 and 2, respectively, the dust collecting gutter 17 is mounted. The dust separated from the central third introduction pipe 7 goes down along the trough 17 without being mixed with ambient air and dust.

The second filter 13 with a large gap for exchange is mounted in a protective box and the position of this pipe is limited by the oblique inclined wall 18. This is necessary to prevent dust from accumulating in the area where air escapes from the dust settling hopper 2.

The slate 15 and the following photo element are adjusted vertically when dust builds up above the limit. Mining in the dust separation hopper 2 consists of blocks 19.

If several aerodynamic dust separation modules 1 are connected as shown in FIGS. 3 and 5, the second, third and fourth inlet pipes 6, 7, 8 may be moved to one end of the dust settling hopper 2. have.

The second, third and fourth introduced pipes 6, 7 and 8 shown in FIGS. 6 to 8 are flexible and at the same time resistant to corrosion due to the movement of dust particles moving along the pipes with the gas flow.

As shown in FIG. 6, the outer cover 20 is flexible and maintains a vacuum state of all pipes. A compression spiral 21 is mounted inside the outer cover 20, and the compression spiral 21 forms a metal base of dust ingress.

The outer cover 20 itself, on which the compression spiral 21 is mounted, is pressed along the end of the bushing of the limit 22.

The aerodynamic dust separation module 1 connects the first limit 22 and the dust precipitation hopper 20 to the second nut 24.

7 shows a second type of dust inlet pipe. In this pipe, the spiral inside the flexible cover is replaced by the movable cover of the cylinder 25.

The hose 26 may be shown in FIG. 8. This hose 26 is reinforced with a metal cover 27.

Connecting the first limit 22 of the first introduction pipe 6 to the inclined wall 18 of the dust settling hopper 2 is made through a flexible diaphragm 28 as shown in FIG. The pram 28 is mounted with bolts 31 between the first and second rings 29 and 30. At this time, the first ring 29 is fixed to the outer surface of the dust settling hopper 2 by sealing as a hard base of the unit. Parts of the limit 32 are mounted to the internal turning in the diaphragm 28 and secured with the first screw 33.

In FIG. 10, the second limit 32 passes through the first gasket 34 and is fixed to the cup 35, and the cup 35 is mounted on the wall of the dust precipitation hopper 2 by sealing.

Figures 11 to 17 show the shape of the dust collection second lock 16. (FIG. 1) The second lock 16 is based on a cup 35 of a cylinder or square section and has a thin edge on the outlet part. . The flat cap 36 is mounted without a gap along the center of the edge, and the flexible second gasket 37 is fixed to the flat cap 36.

According to FIG. 11, there is a flange 38 for mounting a manual lock on the outlet of the dust settling hopper 2. The center clamp of the cover 43 consists of a spring 39, one side of which is mounted to a first pin 40 mounted inside the cup 35 and the other side of the cover flat cap 36. It is attached to the second pin (41) attached to the.

Supporting the rotation of the planar cap 36 is the core 42, which is mounted to a cover having a slight gap opening 43.

When the button 44 is pressed, the cup 36 is opened by the operation of the brace pin 45. The opened cap 36 is fixed by the latch 46.

When the second second button 47 is pressed, the flat cap 36 is fixed in the open state and the flat cap 36 is returned to the original state by the operation of the central spring 39.

Clamp sealing of the lock between fine materials is achieved by minimizing the contact area of the lock with the flexible gasket 37 of the planar cap 36.

The center clamp of the cover 43 can also produce a similar effect.

Figure 12 shows the structure of the automatically operating lock, which is equipped with a cup, the portion of which the cup is mounted to the lock can reduce the angular change of the cap.

Here, the sensor clamp consists of a support 49, which is attached to the lever 50 plate. The other shoulder of the lever is equipped with an electromagnet 51, the position of the electromagnet 51 is adjusted by rotating the core 42.

According to the scheme known in the automation mechanism, when the dust post in the dust settling hopper 2 reaches a certain level, the lock is automatically opened, and when material accumulation stops, it is closed again by the operation of the counterweight motion.

As shown in Fig. 13, although the specific structure of the lock having all the above-mentioned features is shown, in addition to this, the cup has a non-oblique portion. 14 shows the cross section of FIG. 13.

16 shows a lock having a central ball-shaped support 49. The support 49 serves to compress the cap 36 to the cup 35 without a gap. The necessary force is maintained by external pressure and actuation of the brace pin 45 at the second end of the lever 50. The lock is opened by the electromagnet 51.

The type of FIG. 18 makes it possible to mount the electromagnet 52 in the form of a ring nozzle on the outside of the lock cup.

In the above method the magnetic lines of force of the electromagnet are locked via the conductor of the cap or the element of the lever 51, as shown in FIGS. 16 and 18.

In FIG. 18, when the electromagnet 51 is turned on, the lock cap is pressed into the cup 35. The application of the magnet in this case corresponds to the action of the counterweight of FIG. 16.

The operation of the dust sedimentation hopper 2 requires that the air flow entering and exiting the hopper from the hopper matches the discharge pressure of the aerodynamic dust separation module 1 (FIG. 1). This can be solved. In FIG. 19, the basic of the regulating valve 11 is the regulating disk 52, and the position of the regulating disk 52 is inside the cylinder cavity of the regulating valve 11, and at the end thereof, a half-ax ( There is a slit 58 to which 53 and 54 are mounted. One half x 53 of the cavity is mounted in the side hole of the body 2, and another half x 54 rotates with the adjusting disk 56 while moving to the adjusting disk 56. A single interconnected rotation system is then formed. The disc is pressed to the body surface through the collar using a screw 57 head.

Once the screws are loosened, the necessary rotation of the adjusting disk 56 is maintained using the slit 58.

The valve body is finished with a threaded pipe, which is connected to a channel element, which draws air out of the dust settling hopper.

The structure shown allows the production of a more accurate dust air consumption regulator in a smaller size.

When mounting the gas flow sections of an aerodynamic dust separation device as a whole, a problem arises that facilitates the connection of adjacent parts of the sections. 24 to 27 deal with different types.

According to FIGS. 21 and 23, a hard flange or a thin walled flange is connected to the end of the pipe 59 to be connected by using welding or a screw. The flanges form a circular trough along the outer periphery at the connecting junction.

This flange is connected to the flexible sealing line 61 to the gutter after connecting the bolt. Sealing is achieved by relative discharge of the gas flow, thus sealing the gas flow pipe element area.

Figures 23 and 24 show the pipe connection type, which does not require angular rotation for two adjacent flanges. This is because the positions of the attaching holes must coincide in the flange. In addition, the method shown simplifies the assembly of the connecting unit and allows the gas channel to bend.

There are flanges 62,63 at the ends of the pipes 59,60 which have round slopes outside the device.

Tighten pipes 59 and 60 using rings 64 that move from the outside and bolts 65 that act like wedges when mounted to the ring. Sealing of the pipe connection is achieved by mounting the ring sealing line 66 between the flanges. The inner surface of the connected hemispherical flange (FIG. 26) allows one part of the pipe to be turned against the other and thus to bend the gas channel.

25 shows a more simplified flange structure based on a bar type element.

Here, the flanges 62 and 63 are in the form of round profile rings. Pipes 59 and 60 pass through nozzles 68 and 69 and are connected to bolts 67. The nozzles 68, 69 are supported by flanges 62, 63. The number of nozzle pairs required to tighten is at least three.

Using the ring sealing line 66 to form a seal of the connection between the flange element surface and the pipe ending surface, the ring sealing line 66 can also be mounted to the outer part of the profile of the flanges 62, 63.
