Description

Technical Field

[0001] The invention relates to the field of engineering equipment, and in particular to a movable dust removal device. Background Art

[0002] my country has a vast territory and diverse terrain, with a high proportion of mountains and hills. Therefore, in the process of infrastructure construction, some tunnel construction is often required. During tunnel construction, blasting, rock drilling and other operations often generate a large amount of dust in the tunnel, which is harmful to construction workers and construction equipment.

[0003] Since the tunnel uses ventilation channels such as ventilators for forced-in or extraction ventilation and dust removal, this method has a low dust reduction efficiency due to the limited ventilation capacity of the ventilators. Some prior arts, such as a mobile tunnel dust removal device disclosed in publication number CN110185489A, use a traveling disc to drive a flexible ventilator to absorb dust under negative pressure, and use spraying to assist in dust reduction.

[0004] In this type of prior art, for dust treatment, as described in the drawings of the comparative document, the dust is filtered by a dust filter bag and then blown back into a dust hopper for collection. The treatment of dust in the dust hopper is not described. The current common method is to take out the dust hopper and dump it after a certain amount of dust accumulates in the dust hopper.

[0005] This type of dust removal device has the following disadvantages: since the mobile purification device often has a small purification space, the dust filter bag has a small filtering space, and the dust blown back is easily stirred by the wind in the dust hopper to form dust, resulting in a low purification capacity of the dust filter bag; and the mobile dust removal device uses the method of pulling out the dust hopper to discharge dust, which is inconvenient, and the accumulated dust is more easily stirred by the wind.

[0006] Therefore, it is urgent to improve the existing movable dust removal device. Summary of the invention

[0041] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0042] In the present invention, if Figures 1 to 9As shown, a movable dust removal device is provided, comprising: a walking mechanism 2, comprising a vehicle undercarriage 1 and the walking mechanism 2 arranged at the bottom of the vehicle undercarriage 1, the walking mechanism 2 having a front end and a rear end; a dust removal mechanism, arranged at the vehicle undercarriage 1, comprising a shell 3, a first partition plate 4 arranged in the shell 3, the shell 3 having an air inlet 5 on a side facing the front end, the shell 3 having an air outlet 6 on a side facing the rear end, the first partition plate 4 being horizontally arranged in the shell 3, and the shell 3 having an air outlet cavity 7 communicating with the air outlet 6 formed on the upper side of the first partition plate, and the shell 3 having an air outlet cavity 7 communicating with the air outlet 6 formed on the lower side of the first partition plate 4 A filter chamber 8 is connected to the air inlet 5, the first partition plate 4 is provided with ventilation holes, the dust removal mechanism also includes a filter element 9 installed in the ventilation holes, the shell 3 is provided with an openable and closable dust removal plate in the filter chamber 8, the shell 3 forms a dust storage chamber 10 on the lower side of the dust removal plate, and the shell 3 forms a dust exhaust port 11 at one end of the dust storage chamber 10; a dust exhaust mechanism is installed in the dust storage chamber 10, and can move the dust in the dust storage chamber 10 toward the dust exhaust port 11; a dust suction mechanism 12, including an air inlet pipe assembly connected to the air inlet 5; a fan 13, and the fan 13 is connected to the air outlet 6.

[0043] When the dust removal device of the present invention is in use, the entire dust removal device is moved to the area to be cleaned by the walking mechanism 2, and the air inlet 5 is directed toward the dust area, and the fan 13 generates negative pressure, and the air to be cleaned enters the housing 3, and the airflow after being filtered by the filter element 9 passes through the air outlet chamber 7 and is discharged from the housing 3 by the air outlet 6, completing the purification of air dust. During this process, the dust removal plate is in a closed state. For the treatment of dust attached to the filter element 9, after high-pressure backblowing or knocking the filter element 9 in the air outlet chamber 7, the dust attached to the filter element 9 falls to the upper side of the dust removal plate. At this time, the dust removal plate can be opened to allow the fallen dust to fall into the dust storage chamber 10, and then the dust removal plate can be closed to store dust in the dust storage chamber 10. When a certain amount of dust accumulates in the dust storage chamber 10, the dust in the dust storage chamber 10 can be moved toward the dust outlet 11 by the dust discharge mechanism to discharge the dust.

[0044] The beneficial effects of the present invention are that, firstly, by dividing the outer shell 3 into three module areas roughly from top to bottom, temporary storage of the filter in the dust storage chamber 10 is achieved, and the filter is closed during air purification through the openable and closable dust removal plate. On the one hand, the bottom shape of the filter chamber 8 is relatively regular, and the incoming wind flow is not easy to form turbulence. On the other hand, the dust removal plate can reduce the contact between the wind flow and the dust accumulated in the dust storage chamber, thereby reducing the stirring effect of the incoming wind flow on the dust, further reducing the filtration load of the filter element 9, and improving the filtration efficiency.

[0045] Secondly, the present invention can directly store the dust dropped from the filter element 9 in the dust storage chamber 10 by setting a dedicated dust storage chamber 10 at the bottom, and can also form a dust discharge channel in the dust storage chamber 10 to facilitate discharge from one end of the housing 3, which is particularly suitable for the housing 3 to be arranged in an elongated strip shape as a whole, and can increase the filtering space in the filter chamber 8 in the housing 3 by utilizing the length direction space of the undercarriage 1, which is suitable for narrow working conditions such as tunnels. The housing 3 is arranged in an elongated strip shape, and in the setting mode of controlling the length-width ratio between the housing 3 and the undercarriage 1, as a preferred configuration, the ratio between the length h of the filter chamber 8 and the width t of the undercarriage 1 in the housing 3 is greater than or equal to 2.

[0046] Thirdly, when the dust exhaust mechanism discharges dust to the outside, the dust collecting plate can be closed to reduce the dust raising effect of the dust when discharging the dust.

[0047] exist Figure 1 In the embodiment shown, the dust suction mechanism 12 is configured as a dust suction pipe installed at the air inlet 5. Preferably, the dust suction pipe is configured to be retractable and rotatable, and the dust suction pipe can be an existing corrugated dust suction pipe. Alternatively, Figure 1 and Figure 2 As shown, the dust collecting mechanism includes a fixed pipe connected to the housing and a movable pipe movably connected to the fixed pipe, and the movable pipe is adjusted in angle by a cylinder or an oil cylinder. The walking mechanism preferably adopts a crawler walking mechanism.

[0048] Regarding the arrangement of the filter element 9, in the illustrated embodiment, further specifically, as Figure 2 As shown, the filter element 9 includes a filter cartridge. As for the arrangement of the filter element 9, as a preference, a bag filter or a plate filter can also be used.

[0049] exist Figure 1 In the illustrated embodiment, with regard to the setting of the dust collecting plate, more specifically, the dust collecting plate includes two split plate bodies 14, the two split plate bodies 14 are movably connected to the two opposite side walls of the outer shell 3, and the two split plate bodies 14 are configured to be rotatably opened and closed; when the two split plate bodies 14 are closed, the inner edges of the two split plate bodies 14 abut against each other, and the split plate bodies 14 are inclined obliquely inward and downward.

[0050] like Figure 5 and Figure 7 As shown, by configuring the dust collecting plate to be two divided plate bodies 14, the divided plate bodies 14 can form a V-shaped state in a closed state to gather the falling dust, and when the divided plate bodies 14 are opened, the gathered dust can slide down.

[0051] As for the connection method between the sub-board body 14 and the side wall of the housing 3, as a preferred embodiment, Figure 5As shown, the outer edge of the split plate body 14 is connected to the side wall of the outer shell 3 by a rubber connector, so that the split plate body 14 can be installed movably and rotatably, and the split plate body 14 can be connected to the side wall of the outer shell 3, thereby reducing air leakage at the edge of the split plate body 14, further ensuring the stability of the airflow in the filter chamber 8 when the dust collecting plate is closed, and further reducing the stirring and dust-raising effect of the airflow on the dust in the dust storage chamber 10.

[0052] As for the connection between the split board body 14 and the housing 3, as an option, the split board body 14 can also be directly hinged to the side wall of the housing 3 through a rotating shaft. Figure 5 In the two-piece structure shown in FIG, in an optional embodiment, only one dust collecting plate may be provided, one side of the dust collecting plate is movably connected to the side wall of the housing 3, and the other side can abut against the side wall of the other side of the housing 3. Alternatively, more than two sub-plate bodies 14 are used, and each sub-plate body 14 is installed using a shutter-type installation structure.

[0053] As for the driving method of the sub-plate body 14, as a preferred embodiment, more specifically, the dust exhaust mechanism includes a first auger arranged in the dust storage chamber, the first auger includes an auger body 15 arranged in the dust storage chamber and a drive motor 16 arranged on the outside of the shell 3, the drive motor 16 drives the auger body 15 to rotate through a first one-way gear 17, so that when the drive motor 16 rotates forward, the dust in the dust storage chamber 10 is moved toward the dust exhaust port 11, and when the drive motor 16 is reversed, the auger body 15 is stationary; the dust removal device also includes a dust removal plate drive assembly connected to the drive motor 16 and the dust removal plate, the dust removal plate drive assembly includes a second one-way gear 18 connected to the drive motor 16, and the dust removal plate drive assembly is arranged in this way, so that when the drive motor 16 rotates forward, the dust removal plate is stationary, and when the drive motor 16 is reversed, the dust removal plate is driven to open.

[0054] When the dust removal device of the present invention is discharging dust, the dust collecting plate is in a closed state, and the auger body 15 rotates to move the dust toward the dust discharge port 11 by driving the motor 16 to rotate forward to complete the dust discharge. At this time, since there is no action connection between the driving motor 16 and the second one-way gear 18, the dust collecting plate can be kept in a closed state. When it is necessary to drop the dust on the upper side of the dust collecting plate into the dust storage chamber 10, the driving motor 16 reverses to drive the second one-way gear 18 to rotate, so that the dust collecting plate opens and the dust falls into the dust storage chamber 10. At this time, there is no action connection between the driving motor 16 and the auger body 15, which can prevent the auger from rotating to raise the dust.

[0055] The present invention can use the forward and reverse rotation of the driving motor 16 to drive the auger body 15 and the dust collecting plate respectively by providing the first one-way gear 17 and the second one-way gear 18, and use a single power component to drive the two-part action structure, thereby simplifying the driving power structure. Moreover, the motor can only drive one component to move when it is forward and reversed, thereby ensuring that the dust collecting plate and the auger body 15 move in an orderly manner, so as to prevent the problem of dust being raised due to the synchronous action of the two.

[0056] Among them, for the first one-way gear 17 and the second one-way gear 18, those skilled in the art can flexibly select existing one-way gears and one-way gear ring structures when implementing. Figure 1 In the embodiment shown, for the specific arrangement of the one-way gear, further specifically, as shown in FIG. Figure 4 As shown, the first one-way gear 17 is configured as a gear ring with internal teeth, and the outer end of the auger body 15 extends into the inner side of the gear ring of the first one-way gear 17 to form a fit. The second one-way gear 18 is sleeved on the drive shaft of the drive motor 16, and the drive shaft of the drive motor 16 is provided with an outer gear ring meshing with the second one-way gear 18, and the second one-way gear 18 is configured as a gear ring with internal teeth.

[0057] Regarding the manner in which the second one-way gear 18 drives the dust collecting plate to move, in the illustrated embodiment, further specifically, as follows: Figure 5 and Figure 6 As shown, the dust collecting plate is hinged on the side wall of the shell 3, and the bottom surface of the dust collecting plate is provided with an arc-shaped positioning cavity 19, and the dust collecting plate driving assembly also includes: a support shaft 20, which is arranged at the lower side of the dust collecting plate, and the support shaft 20 is provided with a support block 2001, and the support block 2001 can rotate in and out of the positioning cavity 19, and when the support block 2001 is located in the positioning cavity 19, the support block 2001 is approximately perpendicular to the dust collecting plate, and the dust collecting plate is closed, and when the support block 2001 is separated from the positioning cavity 19, the dust collecting plate moves downward to open; a transmission wheel 21, which is arranged on the outside of the shell 3 and is connected to the support shaft 20, and the transmission wheel 21 is connected to the second one-way gear 18 in transmission.

[0058] like Figure 5 As shown, when the dust collecting plate is closed, the support block 2001 cooperates and abuts against the positioning cavity 19. At this time, the direction of the force transmitted by the dust collecting plate to the support block 2001 is roughly directed to the center of the support shaft 20. The support shaft 20 supports the dust collecting plate in a closed state. The positioning cooperation between the support block 2001 and the positioning cavity 19 can conveniently determine the moving position of the support block 2001, and can also position the support block 2001 and maintain it in the supporting position, so that the force direction of the support block 2001 remains directed to the center of the support shaft 20, so as to keep the dust collecting plate stably closed.

[0059] When the dust collecting plate needs to be opened, the second one-way gear 18 rotates to drive the support shaft 20 to rotate, so that the support block 2001 moves out of the positioning cavity 19, and the dust collecting plate moves downward and opens under the action of its own weight and the gravity of the dust to drop the dust into the dust storage cavity 10.

[0060] Through such an arrangement, the dust collecting plate can be opened and closed when the second one-way gear 18 rotates continuously in the same direction.

[0061] exist Figure 5 and Figure 7 In the embodiment shown, Figure 6 and Figure 8 As shown, in order to make the support block 2001 and the positioning cavity 19 move in and out smoothly, one side of the support block 2001 is set to a convex curved surface, and the edge of the positioning cavity 19 is provided with an inclined guide surface. In order to facilitate the dust on the dust collecting plate to fall into the dust storage cavity 10, in the illustrated embodiment, the support shaft 20 is provided with protrusions 31 at intervals except the support block 2001, so that when the protrusions 31 are rotated to the position of the positioning cavity 19, the dust collecting plate can be repeatedly lifted and lowered to promote the dust on the surface of the dust collecting plate to fall.

[0062] The radial direction of the positioning cavity 19 is generally toward the center of the support shaft 20, which means that Figure 6 As shown, the position of the arc surface where the support block 2001 contacts the positioning cavity 19, the diameter direction of the arc surface points to the center of the support shaft 20, so that the force transmitted by the dust collecting plate to the support block 2001 is not easy to cause the support block 2001 to generate torque, so that the support block 2001 can maintain stable support for the dust collecting plate. Among them, the understanding of "roughly facing" is that in an ideal design, the diameter direction of the arc surface is directly opposite to the center of the support shaft 20, but in view of processing and assembly errors, a certain error is allowed between the radial direction of the arc surface and the center of the support shaft 20. Specifically, the radial deviation of the arc surface from the center of the support shaft 20 is less than or equal to 3°. In order to cope with the torque generated by the deviation of the support block 2001 from the arc surface, as an option, a rubber damping member can be set between the support shaft and the housing 3 so that the support shaft 20 can be automatically stabilized.

[0063] exist Figure 5 In the embodiment shown, regarding the arrangement of the dust collecting plate, more specifically, an elastic abutment member 22 is arranged at the inner edge of the dust collecting plate. Figure 6 As shown, by providing the elastic abutment 22, the air tightness of the dust collecting plate when closed can be further ensured, and the dust in the dust storage chamber 10 can be further prevented from being lifted up by the wind flow after forming turbulence. The elastic abutment 22 is configured as an arc-shaped rubber sheet in the illustrated embodiment.

[0064] Regarding the arrangement of the dust removal plate drive assembly, in an optional embodiment, it is also possible to Fig. 9 The arrangement shown, the dust removal plate drive assembly also includes:

[0065] a rack 23, arranged vertically and meshing with the second one-way gear 18;

[0066] The transmission gear 24 is meshed with the rack 23 and connected to the dust collecting plate. The transmission gear 24 can drive the dust collecting plate to open and close. When the driving motor 16 is reversed, the dust collecting plate is opened through the rack 23 and the transmission gear 24.

[0067] The reset member 25 is arranged on the rack 23, and the reset member 25 provides the rack 23 with a force to drive the transmission gear 24 to close the dust removal plate.

[0068] exist Fig. 9 In the embodiment shown, the reset member 25 is configured as a spring, the lower end of the spring abuts against the rack 23, and the upper end abuts against the mounting plate mounted on the housing 3. The transmission gear 24 is coaxially hingedly mounted on the side wall of the housing 3 with the dust collecting plate. When the second one-way gear 18 rotates as shown in the figure, the rack 23 moves upward, compresses the spring and drives the dust collecting plate to rotate downward and open, so that the dust falls into the dust storage chamber 10. When the drive motor 16 rotates in the reverse direction, there is no action connection between the drive motor 16 and the second one-way gear 18. Under the action of the gravity of the spring and the rack 23, the rack 23 moves downward, and the transmission gear 24 drives the dust collecting plate to close.

[0069] In the above-mentioned embodiment, the dust collecting plate is opened and closed by driving the driving motor 16, but this does not limit the present invention. In optional embodiments, the dust collecting plate can also be opened and closed by other means, such as using a dedicated motor to drive the dust collecting plate to rotate; or, using a cylinder or oil cylinder to be hinged to the dust collecting plate, and the dust collecting plate is driven to rotate and open and close by the extension and contraction of the cylinder or oil cylinder.

[0070] In a preferred embodiment, a further optimized setting is that a second vertically arranged partition plate 26 is further provided in the outer shell 3, the first partition plate 4 is provided on the side of the second partition plate 26 facing the air outlet 6, and the outer shell 3 forms a front cavity with an open bottom on the side of the second partition plate 26 facing the air inlet 5, and a dust shield plate 27 is provided in the front cavity; a dust collecting opening 28 is formed on the part of the dust collecting plate facing the air inlet 5, and the dust collecting plate extends obliquely upward at the part close to the front cavity.

[0071] As shown in the figure, by providing the second partition plate 26 and the dust shield plate 27, large dust particles can enter the front chamber, be blocked by the dust shield plate 27, and then fall into the dust opening 28, and fall into the dust storage chamber 10 through the dust opening 28, thereby improving the filtering efficiency and reducing the filtering load of the filter element 9. By tilting the dust shield plate obliquely upward toward the front chamber, the volume of the dust storage chamber 10 near the front chamber can be increased to store more dust. Moreover, the cross-section of the filter chamber 8 on the lower side of the second partition plate 26 in the direction away from the air inlet 5 tends to gradually increase, so that the flow rate of the wind can be gradually reduced in this part, so that the flow rate at the wind dust shield plate 27 is relatively fast, and lighter dust can be blown into the filter chamber 8 for filtration and dust removal, and large particles of dust fall from the dust shield plate 27, thereby playing the role of separately treating dust of different particle sizes, so that the dust can fall relatively evenly when it falls into the dust storage chamber 10, and the dust storage space of the dust storage chamber 10 is further utilized.

[0072] It should be noted that, in the present invention, the dust collecting opening 28 is provided. When the dust collecting plate is in the closed state, although the dust collecting plate has an opening for airflow to enter and exit, this opening is only opened at one end close to the dust discharge port, and the wind shielding function of the dust shield 27 can still be maintained for most areas of the dust storage chamber 10. Moreover, most of the dust accumulated in the dust collecting opening 28 is large-particle dust, and this part of the dust is not easy to be raised. This dust collecting opening does not affect the use of the present application.

[0073] In an optional embodiment, the dust removal opening 28 may not be provided on the lower side of the front cavity, and the dust shield plate 27 may extend uniformly to the inner wall of the outer shell 3 .

[0074] exist Figure 1 In the embodiment shown, for the dust discharge process, more specifically, as shown in the figure, the dust removal device also includes a second auger 29, the feed section of the second auger 29 is connected to the lower side of the dust discharge port 11, and the upper end of the second auger 29 extends obliquely outward to the side of the housing 3. Figure 1 As shown, by setting the second auger 29, the dust in the dust outlet can be discharged from the side of the housing 3, so as to facilitate the collection of dust by bagging or other methods. Moreover, the setting of the second auger 29 increases the resistance of the air flow at the second auger 29, so as to reduce the air leakage path between the second auger 29, the dust outlet 11 and the first auger.

[0075] exist Figure 1 In the embodiment shown, a further optimized arrangement is that a temporary storage chamber 30 is provided at the lower side of the dust discharge port 11, and the second auger 29 is connected to the temporary storage chamber 30. Figure 1 and Figure 2As shown, by providing the temporary storage chamber 30, part of the dust can be moved to the temporary storage chamber 30 during use, so that the connection between the second auger 29 and the first auger is closed by the dust, thereby reducing air leakage there.

[0076] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0077] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
