Description

Technical Field

[0001] The present invention belongs to the technical field of environmental protection dust removal equipment, and particularly relates to a dust removal device and method during the decoration wall surface treatment process. Background Art

[0002] A dust removal device is an environmental protection device used to separate dust and particulate matter from flue gas or air, and mainly achieves purification through principles such as physical interception, inertial collision, electrostatic adsorption, or wet scrubbing. During daily decoration, wall decoration is involved, including operations such as painting and plastering the wall surface, which will inevitably generate dust, seriously affecting the working environment and putting decoration workers in a harsh environment.

[0003] Chinese Patent with application number 202120382203.7 discloses a wall construction dust prevention device for construction projects, including a base, a first outer shell, a dust collection box, and a second outer shell. A first outer shell is installed on the top of the base, and sliding rails are installed on both sides of the inner bottom of the first outer shell. A chute is slidably installed on the sliding rails, and a dust collection box is installed on the top of the chute. A filtration chamber is arranged in the dust collection box. A second outer shell is installed on the top of the first outer shell. Sound absorption holes are arranged on the second outer shell, and a fan is installed inside the second outer shell. Brackets are installed on the top of the first outer shell on both sides of the second outer shell, and dust suction ports are installed on the top of the brackets. This patent slides a dust collection box inside the first outer shell. By opening the alloy door, the dust collection box can be taken out and the dust can be processed separately, avoiding the trouble of cleaning the dust inside the device due to the fixed device, and effectively improving the convenience of centralized dust treatment of the device.

[0004] During the wall decoration process, a roller brush or a grinding brush is often used for wall surface treatment. At this time, a fixed dust removal device is difficult to meet the dust treatment requirements brought about by changes in different positions. Moreover, it is troublesome to fix the dust removal device on the brush head and it is not easy to disassemble and maintain. At the same time, for different wall surface treatments, how to make the dust removal device flexibly adapt to meet different dust removal requirements is also a problem. And, in the case of wall decoration treatment where a large amount of dust is easily generated, how to ensure efficient dust removal and prevent blockage is also the research focus of such dust removal devices.

[0010] Even further, sliding holes are opened through the four corners of the slider, and the sliding holes are slidably connected to the corresponding sliding rods.

[0011] Furthermore, a dust handling mechanism is fixedly provided at one end of the air inlet pipe away from the butt threaded head, and the dust handling mechanism comprises an intermediate pipe, and the two ends of the intermediate pipe are respectively fixedly connected to an upper limit ring and a lower limit ring; the intermediate pipe sleeve is provided with an annular groove, and the top of the annular groove is fitted with the upper limit ring; four toggle plates are evenly fixedly provided at the inner bottom of the annular groove; four toggle plates form four processing spaces, and a pair of vents are symmetrically opened on the upper limit ring; four through grooves are evenly opened at the bottom of the four processing spaces of the annular groove;

[0013] Furthermore, a stepper motor is fixedly mounted on the upper limit ring, and an outer gear ring is fixedly provided on the outer side wall of the ring groove; a gear on the output end of the stepper motor meshes with the outer gear ring.

[0016] Furthermore, the limiting block is a triangular block structure.

[0017] The present invention also claims a method for removing dust using the dust removal device in the process of treating the wall surface for decoration, comprising the following steps:

[0018] S1. Connect the butt-jointed threaded head at one end of the butt-jointed rod to the wall surface treatment device, and insert the air inlet pipe from the other end of the butt-jointed rod so that the guide plate abuts against the limit ring; when the wall surface treatment device is treating the decorated wall surface, turn on the vacuum pump to remove dust;

[0019] S2, manually changing the relative position of the air inlet pipe and the docking rod to change the direction of the guide plate, and then continuing the dust removal operation after further limiting and fixing it through the limiting mechanism;

[0020] S3. By operating the stepper motor, the annular groove rotates in a fixed-angle cycle, so that two treatment spaces are evacuated and dust is collected, and the other two treatment spaces are statically dust-discharged.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The cooperation of the docking rod, the intake pipe and the docking guiding mechanism in the present invention can not only quickly fix and disassemble the intake pipe on the docking rod, avoiding cumbersome installation operations, but also quickly change the corresponding distance between the intake pipe and the wall, so as to be applicable to different wall treatment works; specifically, when the intake pipe needs to be installed on the docking rod, the inner pipe is sleeved on the docking rod and the intake pipe is moved towards the docking threaded head side. When the intake pipe moves, the guide plate deflects, so that the limiting effect of the limiting ring can be ignored; after reaching the specified position, stop moving. Due to the action of the first torsion spring, multiple guide plates clamp the docking rod, and the limiting ring abuts and limits one end of the guide plate, so as to achieve quick fixation; when quick disassembly is required, move the intake pipe in the reverse direction. Due to the limiting effect of the limiting ring, when the intake pipe moves in the reverse direction, the slider slides along the slide rod, so that multiple guide plates can deflect reversely smoothly, and the intake pipe moves in the reverse direction quickly for disassembly, comprehensively avoiding cumbersome installation operations; at the same time, during the process of painting or scraping powder during wall decoration, the degree of dust generation is different. By moving the intake pipe, the corresponding distance between the intake pipe and the wall can be quickly changed, so that the intake pipe is far from the wall during painting, and the splashing of paint can be prevented from polluting the intake pipe. When scraping powder, the intake pipe is close to the wall, which can quickly and effectively remove dust, so as to be applicable to different wall treatment works.

[0023] (2) Through the cooperation of the docking guiding mechanism and the limiting mechanism in the present invention, while the intake pipe can be quickly fixed on the docking rod, the dust removal direction can also be quickly changed, so as to be applicable to different wall dust removal requirements; specifically, when the intake pipe is quickly fixed by moving it, the inclination direction of the guide plate is fixed at this time, so the dust removal direction is fixed. However, when meeting different wall dust removal requirements, the corresponding distance between the intake pipe and the wall is usually adjusted. At this time, if the dust removal direction is not adjusted adaptively, the dust removal range will be affected. At this time, only need to continue to change the relative position between the intake pipe and the docking rod, so that the guide plate presses against the limiting ring, so as to realize the deflection of the guide plate to ensure the dust removal direction and range, and then rotate the outer threaded ring block to make the limiting block deflect and limit and abut against the docking rod to realize fixation, so as to fix the guide plate and be applicable to different wall dust removal requirements.

[0024] (3) The present invention can collect dust quickly and discharge dust by gravity through the structural design of the dust treatment mechanism, thereby realizing efficient dust removal and efficient operation to prevent blockage. Specifically, when wall treatment is being carried out, the vacuum pump is started to perform vacuuming simultaneously, and the gas containing dust enters the two dust collection processing spaces through the air inlet pipe and the air vent. After a period of accumulation, the stepper motor runs and stops the vacuum pump to pump air, and drives the ring groove to rotate through the engagement of the gear and the outer gear ring. At this time, since the toggle plate is fixed, the ring groove will drive the dust treatment space to move above the collection slot when the ring groove rotates. At this time, the vacuum pump continues to operate to collect dust, and the dust treatment space originally collected by the dust is closed by the upper limit ring, so that the dust is stationary at the bottom of the treatment space by gravity, and then the toggle plate is driven to toggle the dust at this position into the collection slot to be discharged when the ring groove rotates later. Therefore, it can collect dust quickly and discharge dust by gravity at the same time, thereby realizing efficient dust removal and efficient operation to prevent blockage.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0037] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

[0038] Example

[0039] like Figures 1 to 9As shown, a dust removal device in the process of decorating wall surface treatment includes a docking rod 100. One end side wall of the docking rod 100 is evenly and fixedly provided with a plurality of limit rings 110, and a docking thread head 120 is provided at the end. An air inlet pipe 200 is sleeved on the docking rod 100. The air inlet pipe 200 includes an inner pipe 220 and an outer pipe 210. One ends of the inner pipe 220 and the outer pipe 210 are hermetically fixed to each other. A plurality of air inlet notches 211 are evenly formed on the side wall of the outer pipe 210. A plurality of mounting notches 221 are evenly formed on the side wall of the inner pipe 220. A limit guiding mechanism 400 is installed on the mounting notch 221, and the limit guiding mechanism 400 is located in the corresponding air inlet notch 211. The end of the air inlet pipe 200 away from the docking thread head 120 is communicated with an air extraction pump 800.

[0040] The cooperation of the docking rod 100, the air inlet pipe 200 and the docking guiding mechanism 400 in the present invention can not only quickly fix and disassemble the air inlet pipe 200 on the docking rod 100, avoiding cumbersome installation operations, but also quickly change the corresponding distance between the air inlet pipe 200 and the wall surface, so as to be applicable to different wall surface treatment works; detailed description will be made later.

[0041] It is worth noting that the docking thread head 120 can be used to connect external devices such as a roller brush for wall surface decoration treatment, which will not be described in detail here.

[0042] Furthermore, the limit guiding mechanism 400 includes a square groove 410, and the square groove 410 is fixedly installed on the corresponding mounting notch 221. Limit plates 420 are fixedly arranged around the upper and lower notches of the square groove 410. A sliding rod 430 is fixedly arranged between the upper and lower corresponding limit plates 420. A slider 440 is slidably connected to the four sliding rods 430. A rotating groove 442 is formed through the slider 440, and a guiding plate 450 is arranged in the rotating groove 442. First rotating rods 460 are fixedly arranged on both sides of the guiding plate 450, and the first rotating rods 460 are rotatably connected to the rotating groove 442. A first torsion spring is sleeved on the first rotating rod 460, and both ends of the first torsion spring are fixedly connected to the guiding plate 450 and the rotating groove 442 respectively.

[0043] When the air intake pipe 200 needs to be installed on the docking rod 100, the inner tube 220 is sleeved on the docking rod 100 and the air intake pipe 200 is moved toward the docking threaded head 120. When the air intake pipe 200 moves, the guide plate 450 is deflected so that the limiting effect of the limiting ring 110 can be ignored. After reaching the specified position, the movement stops. Due to the effect of the first torsion spring, the multiple guide plates 450 clamp the docking rod 100, and the limiting ring 110 abuts against one end of the guide plate 450 to limit the position, thereby achieving rapid fixation. When rapid disassembly is required, the air intake pipe 200 is moved in the opposite direction. Due to the limiting effect of the limiting ring 110, the air intake pipe 200 is When 200 moves in the reverse direction, the slider 440 will slide along the slide rod 430, so that the multiple guide plates 450 can be smoothly deflected in the reverse direction, and the air inlet pipe 200 can be quickly moved in the reverse direction for disassembly, thereby comprehensively avoiding cumbersome installation operations; at the same time, when painting or powdering during wall decoration, the degree of dust generation is different. The movement of the air inlet pipe 200 can quickly change the corresponding distance between the air inlet pipe 200 and the wall, so that the air inlet pipe 200 is far away from the wall when painting, and the splashing of paint can be prevented from contaminating the air inlet pipe 200. When powdering, the air inlet pipe 200 is close to the wall, which can quickly and effectively remove dust, thereby being suitable for different wall treatment tasks.

[0044] It is worth noting that the present invention does not impose any specific limitations on size and proportion, which can be adjusted according to practical applications and will not be described in detail here.

[0045] Furthermore, a return spring 431 is sleeved on the slide bar 430, and the return spring 431 is located above the slider 440. The slider 440 is limited and pressed by the return spring 431, so that it can play a limiting role without hindering the subsequent reverse deflection of the guide plate 450.

[0046] Furthermore, four corners of the slider 440 are penetrated with sliding holes 441, and the sliding holes 441 are slidably connected with the corresponding sliding rods 430. The slider 440 can slide along the sliding rod 430 through the limitation of the sliding rod 430.

[0047] Further, a dust handling mechanism 500 is fixedly provided at one end of the air inlet pipe 200 away from the butt threaded head 120, and the dust handling mechanism 500 includes an intermediate pipe 510, and the two ends of the intermediate pipe 510 are respectively fixedly connected to an upper limit ring 530 and a lower limit ring 520; the intermediate pipe 510 is sleeved with an annular groove 600, and the top of the annular groove 600 is fitted with the upper limit ring 530; four toggle plates 540 are evenly fixedly provided at the inner bottom of the annular groove 600; the four toggle plates 540 form four processing spaces, and a pair of vent holes 550 are symmetrically opened on the upper limit ring 530; four through grooves 620 are evenly opened at the bottom of the four processing spaces of the annular groove 600;

[0048] An air outlet 570 is provided on the lower limit ring 520 located below the air vent 550, and a filter is fixedly provided on the air outlet 570, and an air pump 800 is fixedly installed on the air outlet 570; a pair of collecting slots 560 are symmetrically provided on the lower limit ring 520, and the collecting slots 560 and the air outlet 570 are evenly spaced in the circumferential direction; a collecting box 900 is installed on the collecting slot 560.

[0049] It is worth noting that the electric equipment such as the vacuum pump 800 of the present invention are all controlled by an external power supply, which will not be described in detail here.

[0050] Furthermore, a stepper motor 700 is fixedly mounted on the upper limit ring 530 , and an outer gear ring 610 is fixedly provided on the outer side wall of the annular groove 600 ; a gear 710 on the output end of the stepper motor 700 meshes with the outer gear ring 610 .

[0051] The present invention can not only collect dust quickly but also discharge dust by gravity through the structural design of the dust handling mechanism 500, thereby achieving efficient dust removal and efficient operation to prevent blockage; specifically, when wall treatment is being performed, the vacuum pump 800 is started to perform vacuuming simultaneously, and the dust-carrying gas enters the two dust collection processing spaces through the air inlet pipe 200 and the air vent 550; after a period of accumulation, the stepper motor 700 runs and stops the vacuum pump 800, and the ring groove 600 is driven to rotate through the meshing of the gear 710 and the outer gear ring 610; at this time, due to the toggle plate 540 is fixed, so when the annular groove 600 rotates, it will drive the processing space with dust to move above the collecting groove 560; at this time, the vacuum pump 800 continues to operate to collect dust, and the processing space that originally collected dust is closed by the upper limit ring 530, so that the dust is stationary at the bottom of the processing space through gravity, and then when the annular groove 600 rotates later, the toggle plate 540 drives the dust at this position to fall into the collecting groove 560 and be discharged, so that the dust can be collected quickly and the dust can be discharged by gravity at the same time, thereby achieving efficient dust removal and efficient operation to prevent blockage.

[0052] Furthermore, the annular groove 600 includes an outer groove wall 601 and an inner groove wall 602, wherein the inner groove wall 602 is sealed with the intermediate tube 510, and the outer groove wall 601 is sealed with the bottom of the upper limit ring 530. The sealing performance can be further improved by rubber blocks, etc., which will not be described in detail here.

[0053] Further, two externally threaded ring blocks 230 are symmetrically and fixedly provided at the closed ends of the inner tube 220 and the outer tube 210. A limiting mechanism 300 is installed on the two threaded ring blocks 230. The limiting mechanism 300 includes an internally threaded ring 310, and the internally threaded ring 310 is threadedly connected to the two externally threaded ring blocks 230; a limiting block 320 is rotatably connected between the two externally threaded ring blocks 230 through a second rotating shaft 330. A second torsion spring 340 is sleeved on the second rotating shaft 330, and the two ends of the second torsion spring 340 are fixedly connected to the limiting block 320 and the externally threaded ring block 230 respectively.

[0054] Through the cooperation of the docking guiding mechanism 400 and the limiting mechanism 300, the present invention can not only quickly fix the air inlet pipe 200 on the docking rod 100, but also quickly change the dust removal direction, so as to meet the dust removal requirements of different wall surfaces; specifically, when the air inlet pipe 200 is quickly fixed by moving it, the inclination direction of the guiding plate 450 is fixed at this time, so the dust removal direction is fixed. However, when meeting the dust removal requirements of different wall surfaces, the corresponding distance between the air inlet pipe 200 and the wall surface is usually adjusted. At this time, if the dust removal direction is not adaptively adjusted, the dust removal range will be affected. At this time, only need to continue to change the relative position between the air inlet pipe 200 and the docking rod 100, so that the guiding plate 450 presses against the limiting ring 110, so as to realize the deflection of the guiding plate 450 to ensure the dust removal direction and range. Then, by rotating the externally threaded ring block 230, the limiting block 320 deflects to limit and abut against the docking rod 100 to realize fixation, so as to fix the guiding plate 450 and meet the dust removal requirements of different wall surfaces.

[0055] Furthermore, the limiting block 320 is of a triangular block structure. The limiting operation on the docking rod 100 is quickly realized through the triangular block structure.

[0056] A dust removal method using the dust removal device in the above-mentioned decoration wall surface treatment process includes the following steps:

[0057] S1. Connect the docking thread head 120 at one end of the docking rod 100 to the wall surface treatment device, and sleeved the air inlet pipe 200 from the other end of the docking rod 100, so that the guiding plate 450 abuts against the limiting ring 110; when the wall surface treatment device processes the decoration wall surface, turn on the air extraction pump 800 for dust removal;

[0058] S2. Manually change the relative position between the air inlet pipe 200 and the docking rod 100 to change the direction of the guiding plate 450, and then further limit and fix it through the limiting mechanism 300 and continue the dust removal operation;

[0059] S3. Through the operation of the stepping motor 700, the ring groove 600 rotates in a fixed angle cycle, so that the two treatment spaces are evacuated and dust collected, and the other two treatment spaces are statically discharged.

[0060] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, several improvements and modifications can be made, and these all fall within the protection scope of the present invention.
