Description

Technical Field

[0001] The invention relates to the technical field of construction engineering dust collection, and in particular to a construction engineering dust collection device. Background Art

[0002] In the construction sites of existing civil engineering projects, template plates, steel bars, etc. are usually cut. During the cutting process, a lot of dust will be generated and accumulated in the site. In order to prevent the dust from affecting the health of construction workers, dust collection devices are usually used to collect the dust.

[0003] Existing construction sites of civil engineering projects use a variety of methods to collect dust.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Reference Figure 1-Figure 4 , a dust collection device for civil construction engineering construction, comprising a collection box 1;

[0050] Dust collection unit: The dust collection unit is used to efficiently collect dust in the construction site;

[0051] The dust collecting part includes a servo motor 15 fixedly installed in the collecting box 1, and an auxiliary mechanism is installed on the collecting box 1. The auxiliary mechanism includes a back cushion 3 fixedly installed on the collecting box 1, and two retractable straps 4 for fixing are fixedly installed on the collecting box 1, and the two retractable straps 4 are respectively located on both sides of the back cushion 3;

[0052] When the device is in use, the operator can place his back on the back cushion 3, and then pull the two retractable straps 4 to carry them on the shoulders of the operator to complete the installation. When using it again, the operator can carry the device to a suitable position to start working, which is more convenient to operate and can effectively increase the range of dust collection;

[0053] In a further embodiment, a middle processing box 13 is fixedly installed in the collection box 1, and two collection hoses 2 are fixedly connected between the middle processing box 13 and the collection box 1, and the lower part of the middle processing box 13 is fixedly connected to the dust processing box 14 through a connecting pipe 20, and an air guide mechanism is installed between the servo motor 15 and the collection box 1;

[0054] The air guide mechanism includes an air intake filter box 10 fixedly mounted on the collection box 1, a built-in filter box 31 fixedly mounted on the dust treatment box 14, an air induced draft tube 32 fixedly connected between the built-in filter box 31 and the air intake filter box 10, a driving roller 36 fixedly mounted on the driving end of the servo motor 15, an air induced draft blade 49 fixedly mounted on the driving roller 36, and the air induced draft blade 49 is located in the air induced draft tube 32;

[0055] When the servo motor 15 starts to rotate forward, it will drive the driving roller 36 and the induced draft blade 49 to rotate forward. When the induced draft blade 49 rotates forward, positive suction will be generated, so that the external air and dust can be guided out through the two collecting hoses 2, the middle processing box 13, the connecting pipe 20, the dust processing box 14, the built-in filter box 31, and then through the induced draft tube 32 and the air intake filter box 10, thereby realizing the circulation of air;

[0056] When collecting dust, the operator can hold the two collection hoses 2 and move them to a suitable position and then start the servo motor 15, so that the external dust can be sucked into the inside of the collection box 1, and the collection operation can be completed;

[0057] The two collecting hoses 2 are both made of elastic rubber material, which has a certain elasticity and can be contracted, stretched, or bent, so as to facilitate the collection of dust at multiple angles and multiple positions. Two hanging hooks 9 are provided on the side of the collecting box 1. The two hanging hooks 9 are respectively used to hang the two collecting hoses 2, so as to protect the collecting hoses 2 when not in use and improve the stability of the placement of the collecting hoses 2.

[0058] Reference Figure 3-Figure 15 , the dust treatment part is used to process and recycle the collected dust, and at the same time complete the treatment of the dust on the dust discharge filter 22;

[0059] The dust treatment part includes two dust discharge filters 22 fixedly installed in the middle processing box 13, and the two dust discharge filters 22 are both equipped with dust cleaning mechanisms;

[0060] In a further embodiment, the dust cleaning mechanism includes a driven roller 25 rotatably mounted in the middle processing box 13, two pneumatic blades 27 are fixedly mounted on the driven roller 25, a traction rod 28 is fixedly mounted on the driven roller 25 through a driven wheel 26, a sliding frame 30 is slidably mounted on the inner side of the dust discharge filter 22, a self-resetting shaft 18 is rotatably mounted on the sliding frame 30, and a driven traction plate 29 is fixedly mounted on the self-resetting shaft 18, and the driven traction plate 29 cooperates with the traction rod 28, and a compression elastic rod is fixedly mounted between the sliding frame 30 and the top wall of the middle processing box 13;

[0061] When collecting and removing dust, the external wind will enter the middle processing box 13 through the collection hose 2, and enter the dust processing box 14 through the connecting pipe 20. When the external wind passes through the middle processing box 13, the larger volume of dust impurities in the air will be blocked by the dust discharge filter 22 in the middle processing box 13. At this time, the dust discharge filter 22 will initially filter the dust in the air.

[0062] During the flow of air, the air will impact the two pneumatic blades 27 in the middle processing box 13, thereby driving them to rotate. When the two pneumatic blades 27 rotate, the driven roller 25 and the traction rod 28 thereon will be driven to rotate.

[0063] The driven traction plate 29 is fixed on the self-resetting shaft 18. The self-resetting shaft 18 is a shaft commonly used in the prior art that can automatically reset after rotation, that is, a spring shaft. When the driven traction plate 29 rotates, it drives the self-resetting shaft 18 to rotate, and compresses the spring in the self-resetting shaft 18 while rotating. When the driven traction plate 29 is not subjected to force, the spring in the self-resetting shaft 18 will automatically reset, thereby reversing and pulling the driven traction plate 29 back to its original position.

[0064] A cleaning rod 23 is slidably mounted on the outer side of the dust discharge filter 22, and a connecting guide rod is fixedly mounted between the sliding frame 30 and the cleaning rod 23. Since the traction rod 28 cooperates with the driven traction plate 29, when the traction rod 28 rotates to contact the driven traction plate 29, the rotation of the traction rod 28 will pull the driven traction plate 29 to rotate and move downward, thereby pulling the cleaning rod 23 downward under the cooperation of the sliding frame 30 and the connecting guide rod, so that the dust on the cleaning rod 23 can be scraped off, avoiding the accumulation of too much dust on the cleaning rod 23 to cause blockage, and the dust affecting the efficiency of dust collection;

[0065] In a further embodiment, a collecting structure is installed between the middle processing box 13 and the collecting box 1, and the collecting structure includes a collecting processing box 12 fixedly installed on the collecting box 1, and a dust removal plate 21 is mounted on the collecting processing box 12, and a lower dust box 24 is fixedly connected to the collecting processing box 12, and the upper end of the lower dust box 24 is connected to the middle processing box 13, and an electric opening and closing door is arranged in the lower dust box 24;

[0066] The dust swept by the cleaning rod 23 will accumulate on the collection and processing box 12. The electric self-closing door can be opened regularly to allow the dust to fall into the lower ash box 24 through the collection and processing box 12 and be taken out through the ash removal plate 21, thus completing the dust collection and processing work;

[0067] In a further embodiment, a lifting plate 33 is slidably installed in the dust treatment box 14, and a plurality of connecting plates 34 are fixedly connected to the lifting plate 33, and a connecting mechanism is installed in each connecting plate 34, and the connecting mechanism includes a blocking plate 39 slidably installed in the connecting plate 34, and the blocking plate 39 is in contact with the inner wall of the connecting plate 34;

[0068] When external air suction is performed, the wind enters the dust treatment box 14 and presses the blocking plate 39 in the connecting plate 34 to move it downward and away from the connecting plate 34. At this time, the connecting plate 34 is in a connected state. At this time, the dust filtered by the dust discharge filter 22 is blocked by the built-in filter box 31 and falls to the lower part of the lifting plate 33 in the dust treatment box 14 and is accumulated and stored.

[0069] Two resetting elastic rods 40 are fixedly installed between the blocking disk 39 and the inner wall of the connecting disk 34. The resetting elastic rods 40 play the role of resetting the blocking disk 39. When the blocking disk 39 moves down during dust collection and air extraction, the resetting elastic rods 40 will be stretched. When the air extraction stops, the resetting elastic rods 40 will automatically shrink and reset and pull the blocking disk 39 to automatically move up and reset to block the connecting disk 34.

[0070] In a further embodiment, a lifting mechanism is installed between the servo motor 15 and the lifting plate 33, and the lifting mechanism includes a one-way bearing fixedly installed on the driving roller 36, and a guide cam 38 is fixedly installed on the one-way bearing. An arc guide plate 37 is fixedly installed at the lower part of the lifting plate 33, and the arc guide plate 37 cooperates with the guide cam 38;

[0071] After the dust is collected, the servo motor 15 starts and drives the driving roller 36 and the induced draft blade 49 to rotate in the opposite direction. When the induced draft blade 49 rotates in the opposite direction, the external air is sucked into the dust treatment box 14 through the air intake filter box 10 and the internal filter box 31, that is, air is blown from the outside to the inside of the dust treatment box 14;

[0072] Part of the wind flow entering the dust treatment box 14 will accumulate on the upper part of the lifting plate 33 therein. As the amount of air gradually increases, the air pressure on the lifting plate 33 gradually increases. When the air pressure increases to a certain level, the air will open the blocking disks 39 in the multiple connecting disks 34 on the lifting plate 33, thereby blowing the air and dust on the upper part of the lifting plate 33 downward through the blocking disks 39.

[0073] Two reciprocating spring rods 35 are fixedly installed between the lifting plate 33 and the dust treatment box 14. When the driving roller 36 is reversed, the guide cam 38 is driven to reverse through the one-way bearing. When the guide cam 38 rotates, it will cooperate with the arc guide plate 37. When the guide cam 38 rotates to fit with the arc guide plate 37, the arc guide plate 37 and the lifting plate 33 are pushed upward, and the reciprocating spring rod 35 on the lifting plate 33 is squeezed at the same time. When the guide cam 38 rotates to not fit with the arc guide plate 37, the reciprocating spring rod 35 will automatically extend and reset and push the lifting plate 33 downward, thereby realizing the reciprocating lifting motion of the lifting plate 33.

[0074] The lifting plate 33 also scrapes off the dust attached to the inner wall of the dust treatment box 14 when it moves back and forth, playing a role of auxiliary cleaning;

[0075] The two connecting plates 34 on both sides are both equipped with arc-shaped air guide pipes 41 through a steering mechanism. The steering mechanism includes a gathering bucket fixedly installed at the lower part of the connecting plate 34, and the arc-shaped air guide pipe 41 is rotatably installed at the lower part of the gathering bucket. A steering wheel 43 is fixedly installed at the upper part of the arc-shaped air guide pipe 41, and a plurality of lifting blades 42 are fixedly installed on the steering wheel 43. A positioning baffle 45 is fixedly installed on the steering wheel 43, and a limit block 44 matched with the positioning baffle 45 is fixedly installed on the gathering bucket.

[0076] When the lifting plate 33 moves downward, the arc-shaped air duct 41 and the multiple lifting blades 42 thereon will be driven to move downward. When the multiple lifting blades 42 move downward, they will automatically rotate under the action of air pressure, thereby driving the arc-shaped air duct 41 to rotate a certain angle, so that the arc-shaped air duct 41 rotates to face the built-in filter box 31, and the wind force in the arc-shaped air duct 41 can be blown to the built-in filter box 31 through the connecting plate 34 and the arc-shaped air duct 41, so that the dust adhering to the built-in filter box 31 can be blown downward.

[0077] The positioning baffle 45 cooperates with the limiting block 44 to limit the turning angle of the arc-shaped air guide duct 41, so that the maximum deflection angle after the rotation is toward the internal filter box 31, so that the dust adhering to the internal filter box 31 can always be blown downward;

[0078] The two arc-shaped air guide pipes 41 are initially oriented to face the side wall of the dust treatment box 14, so as to prevent the dust from directly impacting the built-in filter box 31 when collecting dust;

[0079] An ash discharge structure is installed on the dust treatment box 14, and the ash discharge structure includes an ash discharge pipe 19 fixedly connected to the lower part of the dust treatment box 14, and a control valve is provided on the ash discharge pipe 19, and a partition plate 16 is fixedly installed between the dust treatment box 14 and the collecting box 1, and a picking plate 17 is snap-fitted and installed on the collecting box 1. When blowing, the ash discharge pipe 19 will open. At this time, the air entering from the outside will blow the dust and air in the dust treatment box 14 out to the collecting box 1 through the ash discharge pipe 19, and finally the dust will be taken out and collected by taking out the picking plate 17.

[0080] Reference Figure 1 Figure 3 as well as Figure 16-Figure 17 , a spray backwashing part, the spray backwashing part is used to spray dust reduction treatment on the dust and clean the inside of the collection box 1;

[0081] The spray backwashing part includes a water tank 7 fixedly installed at the lower part of the collecting box 1 through a plurality of connecting columns 46, and the water tank 7 is filled with cleaning water. A water supply mechanism is installed between the water tank 7 and the dust treatment box 14, and the water supply mechanism includes a water delivery pump 47 fixedly installed in the water tank 7. A water guide pipe 48 is fixedly connected to the driving end of the water delivery pump 47. Two backwashing water supply pipes 11 are fixedly connected between the water guide pipe 48 and the dust treatment box 14. A water supply pipe 8 is fixedly connected to the water tank 7.

[0082] When the water delivery pump 47 is started, the cleaning water in the water storage tank 7 will be discharged through the water guide pipe 48. The backwashing water supply pipe 11 can be opened to guide the cleaning water into the dust treatment box 14 through the backwashing water supply pipe 11, so as to flush the inside of the dust treatment box 14.

[0083] A water outlet mechanism is installed between the water storage tank 7 and the two collecting hoses 2. The water outlet mechanism includes two telescopic water outlet pipes fixedly connected to the water guide pipe 48, and the two telescopic water outlet pipes are respectively connected to the two collecting hoses 2. The two collecting hoses 2 are both mounted with collecting end pipes 5, and one of the collecting end pipes 5 is provided with a control panel 6;

[0084] After the telescopic water outlet pipe in the water pipe 48 is opened, the cleaning water in the water pipe 48 will also enter the two collecting hoses 2 through the telescopic water outlet pipe, and water mist can be sprayed from the collecting hoses 2 and the collecting end pipe 5, so that the dust in the construction site can be sprayed for dust reduction. This part can be used in conjunction with dust collection. After the spray treatment, the dust collection can be started to collect the dust after the atomized dust reduction.

[0085] The specific dust collection method of this dust collection device is as follows:

[0086] Dust collection: When using the device, the operator can place his back on the back cushion 3, and then pull the two retractable straps 4 to carry it on the operator's shoulders to complete the installation. When using it again, the operator can carry the device to a suitable position and start working;

[0087] When the servo motor 15 starts to rotate forward, it will drive the driving roller 36 and the induced draft blade 49 to rotate forward. When the induced draft blade 49 rotates forward, positive suction will be generated, so that the external air and dust can be guided out through the two collecting hoses 2, the middle processing box 13, the connecting pipe 20, the dust processing box 14, the built-in filter box 31, and then through the induced draft tube 32 and the air intake filter box 10, thereby realizing the circulation of air;

[0088] When collecting dust, the operator can hold the two collecting hoses 2 and move them to a suitable position and then start the servo motor 15 to suck the external dust into the collection box 1, thus completing the collection operation.

[0089] Dust treatment: When collecting and removing dust, the external wind will enter the middle processing box 13 through the collection hose 2, and enter the dust processing box 14 through the connecting pipe 20. When the external wind passes through the middle processing box 13, the larger volume of dust impurities in the air will be blocked by the dust discharge filter 22 in the middle processing box 13. At this time, the dust discharge filter 22 will initially filter the dust in the air;

[0090] When the air flows, it will impact the two pneumatic blades 27 in the middle processing box 13, thereby driving them to rotate. When the two pneumatic blades 27 rotate, they will drive the driven roller 25 and the traction rod 28 thereon to rotate. The traction rod 28 cooperates with the driven traction plate 29. When the traction rod 28 rotates to contact the driven traction plate 29, the rotation of the traction rod 28 will pull the driven traction plate 29 to rotate and move downward, thereby pulling the cleaning rod 23 downward under the cooperation of the sliding frame 30 and the connecting guide rod, so that the dust on the cleaning rod 23 can be scraped off, avoiding the accumulation of too much dust on the cleaning rod 23 to cause blockage, and the dust affects the efficiency of dust collection;

[0091] During external suction, the wind enters the dust treatment box 14 and presses the sealing plate 39 in the connecting plate 34 to move it downward and away from the connecting plate 34. At this time, the connecting plate 34 will be in a connected state. At this time, the dust filtered by the dust discharge filter 22 will be blocked by the built-in filter box 31 and fall to the lower part of the lifting plate 33 in the dust treatment box 14 and be accumulated and stored.

[0092] Dust discharge: After the dust is collected, the servo motor 15 starts and drives the driving roller 36 and the induced draft blade 49 to rotate in the opposite direction. When the induced draft blade 49 rotates in the opposite direction, the external air is sucked into the dust treatment box 14 through the air intake filter box 10 and the internal filter box 31, that is, air is blown from the outside to the inside of the dust treatment box 14;

[0093] Part of the wind flow entering the dust treatment box 14 will accumulate on the upper part of the lifting plate 33 therein. As the amount of air gradually increases, the air pressure on the lifting plate 33 gradually increases. When the air pressure increases to a certain level, the air will open the blocking disks 39 in the multiple connecting disks 34 on the lifting plate 33, thereby blowing the air and dust on the upper part of the lifting plate 33 downward through the blocking disks 39.

[0094] When the driving roller 36 is reversed, the guide cam 38 is driven to reverse through the one-way bearing. When the guide cam 38 rotates, it will cooperate with the arc guide plate 37. When the guide cam 38 rotates to fit the arc guide plate 37, the arc guide plate 37 and the lifting plate 33 are pushed upward, and the reciprocating spring rod 35 on the lifting plate 33 is squeezed at the same time. When the guide cam 38 rotates to not fit the arc guide plate 37, the reciprocating spring rod 35 will automatically extend and reset and push the lifting plate 33 downward, thereby realizing the reciprocating lifting motion of the lifting plate 33.

[0095] When the lifting plate 33 moves downward, the arc-shaped air duct 41 and the multiple lifting blades 42 thereon will be driven to move downward. When the multiple lifting blades 42 move downward, they will automatically rotate under the action of air pressure, thereby driving the arc-shaped air duct 41 to rotate a certain angle, so that the arc-shaped air duct 41 rotates to face the built-in filter box 31, and the wind force in the arc-shaped air duct 41 can be blown to the built-in filter box 31 through the connecting plate 34 and the arc-shaped air duct 41, so that the dust adhering to the built-in filter box 31 can be blown downward.

[0096] When blowing, the dust discharge pipe 19 will be opened. At this time, the air entering from the outside will blow the dust and air in the dust treatment box 14 out to the collection box 1 through the dust discharge pipe 19, and finally the dust will be taken out and collected by taking out the taking plate 17.

[0097] Dust atomization and dust reduction treatment: When the water delivery pump 47 is started, the cleaning water in the water storage tank 7 will be discharged through the water guide pipe 48. The backwash upper water pipe 11 can be opened to guide the cleaning water into the dust treatment box 14 through the backwash upper water pipe 11, so that the inside of the dust treatment box 14 can be flushed;

[0098] After the telescopic water outlet pipe in the water pipe 48 is opened, the cleaning water in the water pipe 48 will also enter the two collecting hoses 2 through the telescopic water outlet pipe, and water mist can be sprayed from the collecting hoses 2 and the collecting end pipe 5, so that the dust in the construction site can be sprayed for dust reduction. This part can be used in conjunction with dust collection. After the spray treatment, the dust collection can be started to collect the dust after the atomized dust reduction.

[0099] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
