Description

Technical Field

[0001] This invention relates to the field of building demolition technology, specifically to a dust suppression machine for building demolition construction. Background Technology

[0002] The demolition of buildings generates a large amount of dust, and the spread of dust can affect the working environment. Therefore, spraying is used to suppress dust and reduce air pollution generated during building demolition.

[0003] Currently, a Chinese patent discloses a dust suppression machine for building demolition, with publication number CN120532228B. In this disclosed technical solution, the spraying range is increased by adding nozzles to the outside of the dust suppression cylinder. Compared with the traditional method of changing the spraying angle and adjusting the horizontal position, the spraying range can be further expanded, the spraying distance can be adjusted, and the liquid dripping near the dust suppression machine can be recycled to reduce the waste of water resources.

[0004] For example, Chinese patent CN119746530B discloses a dust collection device for masonry processing in building construction. In this disclosed solution, the free end of the filter screen is located between spaced-apart limiting blocks. A rotating ball is movably mounted on the rear wall of the collection box. A cantilever and a lever are connected to both sides of the rotating ball. A hammer is located at the free end of the cantilever. A rectangular notch is provided at the lower part of the rear wall of the collection box. The collection box is installed in a drawer-like manner through the rectangular notch at the bottom of the inner cavity of the collection box. A baffle is located on the rear wall of the collection box and fixed to the collection box with bolts to cover the rectangular notch. This device overcomes the shortcomings of traditional dust collection methods, eliminating the need for filter screen disassembly and cleaning, reducing production costs, improving dust collection efficiency, achieving green construction in masonry processing, and avoiding impacts on the health of construction workers and the environment.

[0005] Based on the publicly available technical solutions and existing technologies, the current methods for addressing air dust pollution during the demolition or use of buildings are typically spraying or vacuuming. However, existing dust suppression equipment does not integrate spraying and vacuuming. In existing technologies, when vacuuming, dust can clog the filter, reducing the efficiency of dust absorption. When using tapping to remove dust, the suction force causes the dust to quickly re-adsorb onto the filter, clogging it and making it difficult to achieve a good cleaning effect. Cleaning after shutdown can also affect the vacuuming process. Summary of the Invention

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] This invention provides, for example Figure 1-12 The dust suppression machine for building demolition construction shown includes a movable box 1. The top of the movable box 1 is rotatably connected to a deflector 3 via a rotating shaft 2. A mist cannon 4 is connected to the inner side of the deflector 3 via a connecting rod. The connecting rod can deflect within the deflector 3, thereby supporting the angle adjustment of the mist cannon 4. One end of the mist cannon 4 is connected to a water tank 5 via a connecting pipe.

[0027] A telescopic rod is rotatably connected to the bottom of the other end of the fog cannon 4. The telescopic rod can be manually extended and retracted to adjust its length, which can save costs. The telescopic rod can be used to adjust the tilt angle of the fog cannon 4. The bottom end of the telescopic rod is connected to a baffle plate through a connecting seat. A slider is fixedly connected to the bottom of the baffle plate. A frame 6 is slidably connected to the top of the movable housing 1. The slider is slidably connected to the inside of the frame 6. A rotating rod 7 is slidably connected to the bottom of the inside of the frame 6. A reduction motor 8 is connected to the bottom end of the rotating rod 7. The reduction motor 8 is installed on the top of the inner wall of the movable housing 1. When the rotating rod 7 is rotated by the reduction motor 8, the rotation of the rotating rod 7 can drive the frame 6 to move back and forth, thereby moving the slider to drive the fog cannon 4 to spray dust in different directions at 45 degrees.

[0028] The bottom end of the rotating shaft 2 is connected to the dust collection assembly 9 via a flange. A high-pressure suction pump body 10 communicating with the dust collection assembly 9 is installed inside the movable housing 1. Both sides of the dust collection assembly 9 are connected to dust collection boxes 12 via suction pipes 11. The dust collection boxes 12 are located on both sides inside the movable housing 1. Dust inlets are evenly spaced on one side of the dust collection box 12. After the dust collection box 12 is removed, it is placed at a low position on the bottom so that the splashed dust can be absorbed through the dust collection box 12, reducing the dispersion of dust. The sucked-in dust enters the dust collection assembly 9 for filtration. A collection trough for dust to fall is provided at the bottom of the dust collection assembly 9. The collection trough can be removed from the movable housing 1.

[0029] The dust collection assembly 9 includes a cylinder 91. A bottom plate 92 is fixedly connected to the bottom of the inner side of the cylinder 91. An air extraction channel is opened on the inner side of the bottom plate 92. One end of the air extraction channel is connected to the high-pressure suction pump body 10. A grooved cylinder 93 is fixedly connected to the top of the bottom plate 92. External dust removal structures 94 are evenly arranged on the outer side of the grooved cylinder 93. Internal dust removal structures 95 are evenly arranged on the inner side of the grooved cylinder 93. A dust filter cylinder 96 is arranged on the inner side of the grooved cylinder 93. A ring body 97 is rotatably connected to the top of the grooved cylinder 93. A shielding ring cover 98 is fixedly connected to the top of the grooved cylinder 93 on the outer side of the ring body 97. A sealing assembly 99 is arranged on the top of the inner side of the cylinder 91. After the high-pressure suction pump body 92 is started, the suction force is used to make the cylinder 91 collect dust through the air extraction channel of the bottom plate 92. The dust collected is filtered through the outside of the dust filter cylinder 96.

[0030] The cover assembly 99 includes a cover plate 9901 adapted to the flange. A vertical shaft 9902 is fixedly connected to the center of the bottom of the cover plate 9901. The outer side of the vertical shaft 9902 is provided with slots at equal intervals. A deflection stop bar 9903 is rotatably connected to the inner side of the slots. Extrusion rollers 9904 are installed at equal intervals on the outer side of the top of the cover plate 9901. Insert rods are fixedly connected at equal intervals to the bottom of the cover plate 9901. The top of the filter cylinder 96 is provided with an insertion hole adapted to the insert rod. After the filter cylinder 96 and the cover plate 9901 are installed, the rotation of the cover plate 9901 can drive the filter cylinder 96 to rotate. An extrusion ring is also provided on the outer extension of the bottom of the cover plate 9901. During the installation of the cover plate 9901, the extrusion ring can abut against the cover 951, thereby ensuring the contact stability between the cover 951 and the inner wall of the filter cylinder 96.

[0031] The external dust removal structure 94 includes a housing 9401 fixedly connected to the outside of the grooved cylinder 93. The bottom end of the housing 9401 penetrates through the bottom plate 92 and extends to the bottom of the bottom plate 92. Hollow brush shafts 9402 are evenly spaced on the inner side of the housing 9401. The hollow brush shafts 9402 are rotatably connected to the groove opening of the grooved cylinder 93, and the top end of the hollow brush shafts 9402 penetrates through the grooved cylinder 93 and extends into the gap between the ring body 97 and the shielding ring cover 98. A small gear 9403 is sleeved on the outer side of the hollow brush shafts 9402. The outer side is provided with teeth that are compatible with the pinion 9403. The surface of the hollow brush shaft 9402 has evenly spaced, downward-sloping air outlets 9404. A one-way air film is provided inside each air outlet 9404. The one-way air film is a raised rubber membrane with a cross groove in the center. When air is discharged, the cross groove opens due to wind force; when air is sucked in, the cross groove closes due to suction force, preventing dust from entering the hollow brush shaft 9402. A squeeze plug 9405 is slidably connected to the top of the inner side of the hollow brush shaft 9402. A thin rod 9406 is fixedly connected to the top, and an arc-shaped force-bearing plate 9407 is fixedly connected to the top of the thin rod 9406. The compression plug 9405 includes an annular rubber plug 94051, and a frustum-shaped stopper 94052 is provided on the top of the annular rubber plug 94051. Limiting rods are fixedly connected to both sides of the top of the annular rubber plug 94051. The top of the limiting rods passes through the frustum-shaped stopper 94052 and extends to the top of the frustum-shaped stopper 94052. The top of the frustum-shaped stopper 94052 is connected to the thin rod 9406. The filter cartridge 96 moves along with the mist cannon cartridge 4. When the deflector rotates, the rotation of the ring 97 drives the pinion 9403 to rotate through the teeth, allowing the bristles on the surface of the hollow brush shaft 9402 to brush away the dust deposited on the surface of the filter cylinder 96, and the dust falls off through the bottom of the housing 9401. As the cover plate 9901 rotates, the extrusion roller 9904 can extrude the arc-shaped force plate 9407, thereby allowing the thin rod 9506 to extrude the extrusion plug 9405, allowing the air inside the hollow brush shaft 9402 to exit at an angle downwards from the air outlet 9404, improving the efficiency of dust falling off.

[0032] When the thin rod 9506 is pressing, the pressure of the thin rod 9506 is pressed through the frustum stopper 94052 to the annular rubber stopper 94051, so that the frustum stopper 94052 seals the air inlet in the middle of the annular rubber stopper 94051, ensuring that air is rushed out from the air outlet 9404. When the thin rod 9506 returns to its original position, air can be supplied to the air inlet in the middle of the annular rubber stopper 94051, and so on.

[0033] The internal dust removal structure 95 includes a cover 951 that abuts against the inner wall of the filter cylinder 96. The cover 951 has rubber strips on both sides to ensure a tight seal between the cover 951 and the filter cylinder 96. The bottom of the cover 951 is connected to the bottom plate 92. Hollow cavities 952 are evenly spaced along the inner side of the cover 951. Air vents are evenly spaced on the surface of each hollow cavity 952. An air pipe 953 is connected to one side of each hollow cavity 952. An elastic membrane 95 is installed on the inner side of one end of the air pipe 953. 4. One side of the elastic membrane 954 is connected to a push rod 955 via a small ring. The middle part of the push rod 955 is rotatably connected to the installation port opened at the top of the air pipe 953. The inner side of the elastic membrane 954 is connected to the inner wall of the air pipe 953 via two first elastic bands 956. The surface of the hollow cavity 952 is provided with a striking component 957. After the push rod 955 is subjected to force, it can pull the elastic membrane 954, and then use the air pipe 953 to launch an air cannon to impact and remove the dust on the dust filter cartridge 96.

[0034] The striking assembly 957 includes a thin shaft 9571, which is disposed through an air tube 953. Two sealing plates 9572 are sleeved on the outer side of the thin shaft 9571, abutting against the surface of the air tube 953. A transverse groove is formed on the air tube 953 to allow the thin shaft 9571 to move, and this groove can be sealed by the sealing plates 9572 to reduce air leakage. The middle part of the thin shaft 9571 is connected to an elastic membrane 954 via a second elastic band 9573. The top of the thin shaft 9571... Both the top and bottom are fixedly connected to a U-shaped rod 9574. The two ends of the U-shaped rod 9574 pass through the hollow cavity 952 and are connected to rubber balls. The surface of the hollow cavity 952 has a small opening for the rubber balls to move out, so that the impact of the rubber balls can hit the dust filter cartridge 96. During the firing of the air cannon, the elastic membrane 954, through the force of the second elastic band 9573, can make the striking component 957 hit the surface of the dust filter cartridge 96, thereby enhancing the dust removal effect and ensuring the efficiency of subsequent dust intake.

[0035] Hollow covers 13 are connected at equal intervals on the outer side of the shielding ring cover 98. A long shaft 14 is connected through the inner side of the hollow cover 13. A ratchet is connected to the outer side of the long shaft 14 and the inner side of the hollow cover 13. The outer side of the ratchet meshes with the teeth. A spiral blade 15 is installed at the bottom end of the long shaft 14. As the ring body 97 rotates back and forth, the teeth can drive the ratchet to rotate in one direction, so that the spiral blade 15 on the long shaft 14 can discharge the dust deposited in the dust collection tank 1.

[0036] The bottom plate 92 has ash collection grooves 16 evenly spaced on its surface, and spiral blades 15 are disposed inside the ash collection grooves 16. The bottom plate 92 has through openings evenly spaced on its surface for the housing 9401 to pass through.

[0037] Short inserts 17 are provided at equal intervals on the outer side of the cover plate 9901, and vertical slots that are adapted to the short inserts 17 are provided at equal intervals on the inner side of the ring body 97, so that after the cover plate 9901 is installed, the rotation of the cover plate 9901 can drive the ring body 97 to rotate.

[0038] The top of the arc-shaped force plate 9407 is arched and abuts against the extrusion roller 9904. A spring is sleeved on the outside of the thin rod 9406, and a small telescopic cylinder 18 is provided on the outside of the spring. The top and bottom of the small telescopic cylinder 18 are connected to the arc-shaped force plate 9407 and the shielding ring cover 98, respectively, so that the thin rod 9506 can be reset by the small telescopic cylinder 18 and the spring after being extruded.

[0039] The implementation principle of a dust suppression machine for building demolition in this application embodiment is as follows: the water pump in the water tank 5 draws water to the mist cannon 4 through the connecting pipe, and the separation generated in the mist cannon 4 atomizes the water and sprays it out, thereby spraying dust on the demolished building.

[0040] Start the reduction motor 8, the rotation of the rotating rod 7 causes the frame 6 to move back and forth, and the telescopic rod drives the fog cannon 4 to deflect left and right through the slider to spray dust. When the fog cannon 4 deflects, the rotation of the deflection seat 3 drives the rotating shaft 2 to rotate.

[0041] The rotating shaft 2 drives the cover plate 9901 to rotate, and the cover plate 9901 drives the filter cylinder 96 to rotate, so that the filter cylinder 96 rotates from the surface where it filters dust through the slot 93 to the corresponding surface of the housing 9401. At the same time, the ring 97 rotates with the cover plate 9901, so that the ring 97 drives the hollow brush shaft 9402 to rotate and brush away the dust on the surface of the filter cylinder 96. With the extrusion of the extrusion roller 9904, the air in the hollow brush shaft 9402 is expelled from the air outlet. The downward blowing air can better make the dust fall from the bottom of the housing 9401.

[0042] During the rotation of the vertical shaft 9902, the vertical shaft 9902 drives the deflection lever 9903 to rotate. After the deflection lever 9903 is blocked by the push rod 955, the deflection lever 9903 will drive the end of the push rod 955 to deflect, thereby pulling the elastic membrane 954. After the deflection lever 9903 continues to deflect, the deflection lever 9903 will immediately separate from the push rod 955, thereby relieving the force on the elastic membrane 854 and allowing the air pipe 953 to fire an air cannon, which will knock the dust out from the inside of the dust filter cartridge 96, ensuring the dust cleaning effect and further ensuring the efficiency of dust collection.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
