It refers to the materials and equipment used, as well as the technical activities such as survey, design, construction, maintenance, and repair, as well as the objects of engineering construction.

[0003] Dust is generated during the construction process of various sites, so dust in the air is filtered through dust removal devices, such as Figure 1 As shown in Figures a and b in the figure, the existing dust filtering method is to isolate the dust in the air flowing through the shell by the filter plate arranged inside the shell, thereby filtering and removing dust. However, in actual use, the dust is isolated on the left side of the filter plate and it is not convenient to discharge the dust. As the use time increases, too much dust will accumulate on the left side of the filter plate or adhere to the bottom of the filter plate, which will reduce the filtering effect of the filter plate. Dust collection usually requires the shell to be disassembled to complete, and when the dust increases, the dust is easily disturbed or refluxed inside the shell with the flow of airflow, which in turn affects the dust removal efficiency and the normal work of personnel.

DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 13 The present invention provides a technical solution: a dust removal and filtering device for civil engineering, comprising a body 1 and a cylinder 2 arranged on the body 1, a filter plate 3 is arranged inside the cylinder 2, the cylinder 2 is hollow and an exhaust assembly is arranged inside, the exhaust assembly is used to introduce external air into the cylinder 2, and the air is discharged after being filtered by the filter plate 3, a collecting assembly is arranged inside the cylinder 2, and the collecting assembly is used to collect impurities remaining inside the cylinder 2, and the collecting assembly includes a push piece 4, which is located inside the cylinder 2 and can slide left and right inside the cylinder 2; a collecting groove 5 is opened along the axial direction of the cylinder 2 and is located Below the push piece 4; the support plate 6 is arranged in the collecting groove 5; the baffle 8 is located on the right side of the support plate 6 and is slidably connected to the inside of the collecting groove 5; the second spring 9 is fixedly connected to the support plate 6 and the inner wall of the collecting groove 5; the collecting box 10 is arranged on the right side of the baffle 8 and its port is lower than the baffle 8; the slide groove 11 is opened at the right end of the support plate 6 and passes through the support plate 6; the pressure rod 12, the bottom end of which is slidably connected to the inside of the slide groove 11 and the top end is rotatably connected to the top of the baffle 8. When the push piece 4 moves to contact with the pressure rod 12, the baffle 8 can slide down along the inner wall of the collecting groove 5 by pressing the pressure rod 12 downward.

[0031] like Figure 2-Figure 8 As shown:

[0032] The exhaust assembly refers to the fan blades arranged inside the cylinder 2, which are used to introduce the outside air into the cylinder 2 and then isolate the dust and impurities through the filter plate 3, and then the clean air is discharged through the right end of the cylinder 2. The fan blades are prior art and will not be described in detail;

[0033] Before use, the machine body 1 and the cylinder body 2 are moved to the designated working position through the universal wheels with self-locking function at the four corners of the bottom of the machine body 1. The universal wheels can facilitate the carrying and transportation of the machine body 1 and the cylinder body 2 and occupy a small area. The left end of the cylinder body 2 is directed in the opposite direction of dust emission, and then the outside air with dust and impurities is introduced into the cylinder body 2 through the fan blades, thereby starting the dust removal and filtering work;

[0034] The cylinder 2 is placed horizontally, and the support plate 6 is inside the collecting tank 5. At this time, the horizontal height of the support plate 6 is lower than the outer circle of the filter plate 3, and the pressure rod 12 is at this time. Figure 8 In the state of being used for a long time, dust will remain on the left side of the filter plate 3 inside the cylinder 2, and impurities will fall into the collecting tank 5 along the side wall of the cylinder 2. The existence of the collecting tank 5 can provide a relatively static and low-speed area, making it difficult for the dust particles deposited inside to be suspended under the blowing of the airflow, and then the dust and impurities are collected by the collecting tank 5. At this time, the dust is above the supporting plate 6. When the working position of the machine body 1 needs to be moved again, the rotation of the fan blades is stopped, and the impurities inside the cylinder 2 can be cleaned during transportation;

[0035] The cleanup works as follows:

[0036] When the push plate 4 moves to the rightmost side of the support plate 6, the push plate 4 will push the dust accumulated on the surface of the support plate 6 to the right side, so that the dust can be gradually concentrated. When the push plate 4 moves to the left end of the inclined pressure rod 12 and contacts it, it will gradually press the pressure rod 12 while moving to the right. After the pressure rod 12 is pressed down, its left end will slide to the left along the slide groove 11, and its right end will drive the baffle plate 8 to slide down along the inner wall of the collecting groove 5 while rotating and compressing the second spring 9. At this time, the baffle plate 8 will drop relative to the collecting box 10. When the push plate 4 moves to the rightmost side of the support plate 6, the pressure rod 12 will drop to a state where both ends are horizontal. At this time, the top of the baffle plate 8 will drop to a state where the port of the collecting box 10 is at the same height. At this time, the push plate 4 also moves to the rightmost side of the support plate 6, and then pushes the dust above the support plate 6 to the inside of the collecting box 10, so that the dust is retained in the collecting box 10 and will not be temporarily retained in the cylinder body 2.

[0037] When the cleaning work is completed, the push piece 4 is reset to the leftmost position, and the second spring 9 will also lift the baffle 8, thereby raising the baffle 8 to a position to block the port of the collection box 10. At this time, the top end of the pressure rod 12 will rise with the baffle 8, and its bottom end will slide to the right along the inside of the slide groove 11 to the initial inclined position, and then the cylinder 2 can be moved to other positions through the machine body 1 to continue the dust removal work, and the dust can be collected again after the dust removal;

[0038] The present invention has a small size and is easy to transport. When dust is removed at the working position, the dust will fall into the collecting groove 5 and gather. Later, the push piece 4 can be moved from the leftmost side to the rightmost side to make the baffle 8 drop to open the port of the collecting box 10, so that the dust can be collected after each use. There is no need to disassemble the cylinder 2 to complete the dust collection. It is easy to use, and after the dust is collected, it can prevent the fan blades from causing the dust to be disordered and adhere to the filter plate 3 to form lumps when the fan blades rotate.

[0039] The cylinder 2 is rotatably connected to the machine body 1, and two groups of collecting assemblies are provided, and the two collecting assemblies are symmetrically distributed about the cylinder 2; the push pieces 4 in the two collecting assemblies are slidably connected to a push rod 18, and the end of the push rod 18 extends to the outside of the cylinder 2 and is slidably connected to the cylinder 2, and a fourth spring 19 is fixedly connected between the two push pieces 4 and the push rod 18; a push ring 13 is slidably connected to the outside of the cylinder 2, and the push ring 13 is used to push the support plate 6 to slide inside the collecting groove 5, and a first spring 7 is fixedly connected between the support plate 6 and the inner wall of the collecting groove 5, and a driving assembly is provided below the push ring 13, and the driving assembly is used to drive the push ring 13 to slide along the cylinder 2 according to the rotation direction of the cylinder 2.

[0040] like Figure 2-Figure 8 as well as Fig.12 As shown:

[0041] The collecting assembly is provided with two groups and the cylinder 2 is rotatably connected to the machine body 1, so that the cylinder 2 can rotate left and right on the machine body 1. When the cylinder 2 rotates left and right to the limit, the rotating area is greater than 180 degrees, so that the angle of the cylinder 2 can be adjusted without moving the machine body 1, and dust in the left, right and upper directions can be collected;

[0042] The driving assembly is used to drive the push ring 13 to slide along the cylinder 2 according to the rotation direction of the cylinder 2, so when the cylinder 2 rotates to the left or right from the vertical state, the push ring 13 can rotate along the cylinder 2 in the rotation direction of the cylinder 2, that is, when the cylinder 2 is in the vertical state, the left and right ends of the push ring 13 are in contact with the side walls of the two support plates 6, and at this time, the two support plates 6 are both in the middle position of the collecting tank 5 under the action of the first spring 7, that is, at this time, the two push pieces 4 are both outside the push rod 18 and do not compress the fourth spring 19;

[0043] Take the case where cylinder 2 rotates 90 degrees to the left as an example:

[0044] When the cylinder 2 rotates to the left, the driving assembly will make the push ring 13 slide to the left along the cylinder 2. At this time, the left end of the push ring 13 will be out of contact with the left support plate 6, and the right end of the push ring 13 will push the right support plate 6 to slide along the collection groove 5 and stretch the first spring 7 when moving to the left. At this time, the right support plate 6 will push the right push piece 4 to slide along the push rod 18 and compress the fourth spring 19. At this time, the right support plate 6 will contact the push rod 18 and close the collection groove 5. Figure 6 As shown, the support plate 6 at the bottom is still in the middle of the collecting tank 5, and after the right support plate 6 closes the collecting tank 5, the pressure rod 12 will slide inside the slide groove 11 to a horizontal state, and the right support plate 6 will be flush with the end of the baffle 8;

[0045] Then the fan blades can be rotated to guide the gas, and the gas after the guidance is filtered through the filter plate 3 and discharged, and the impurities and dust will remain inside the cylinder 2 but will fall below (with Figure 6 In the collecting tank 5 shown below, i.e. on the left side, when collection is required, it is only necessary to push the left end of the push rod 18 to the right;

[0046] When the push rod 18 moves, it will drive the two push pieces 4 to move rightward synchronously, but the push piece 4 at the top is pushed to the inside of the push rod 18 by the upper support plate 6, so when the push rod 18 moves to the right, it can scrape off the dust attached to the surface of the upper support plate 6, thereby avoiding scaling formed by long-term adhesion, and the lower push piece 4 will push the dust deposited on the collection groove 5 and the support plate 6 during the movement. When the push rod 18 moves to the right to the limit, it will press the lower pressure rod 12 downward from the inclined state, and then lower the lower baffle 8, so that the collected dust enters the interior of the collection box 10 below to complete the collection;

[0047] The upper push piece 4 is inside the push rod 18, and the upper support plate 6 is flush with the baffle 8, and the upper pressure rod 12 is in a horizontal position. Therefore, when the upper push piece 4 moves, it will not press down the upper pressure rod 12, so the upper baffle 8 will not move relative to the collection box 10, so that the upper collection box 10 will not be opened, and the upper collection assembly will not be in a state of collecting dust, but will continue to be in a closed state, which can prevent the impurities in the upper collection box 10 from falling into the interior of the cylinder 2 when the upper collection box 10 contains impurities and the lower collection box 10 is opened synchronously.

[0048] In the present invention, when the cylinder 2 rotates to the left or right, the push ring 13 can push the support plate 6 in the opposite direction so that the support plate 6 is flush with the baffle 8, so that the two collection boxes 10 will not be opened at the same time, thereby ensuring that the dust in the upper collection box 10 will not fall.

[0049] The right end of the support plate 6 is provided with an integral shielding portion 20 , and the baffle plate 8 is provided with a through hole 21 , which corresponds to the height of the chute 11 , and is used to introduce impurities remaining in the chute 11 into the collection box 10 .

[0050] The port of the collecting box 10 is provided with an integral limiting end 22 .

[0051] like Figure 8-Figure 9 as well as Fig.13 As shown:

[0052] When the support plate 6 is not pushed by the push ring 13, the pressure rod 12 is in an inclined state. At this time, the shielding portion 20 is below the through hole 21. Therefore, when the pressure rod 12 is pressed under the push piece 4 to make the baffle 8 drop to be flush with the port of the collection box 10, the dust above the support plate 6 can be pushed into the collection box 10 for collection. Because there may be dust remaining in the chute 11, if there is a lot of dust and it cannot be cleaned, it will affect the normal retraction and release of the pressure rod 12. Through the through hole 21 connected to the inside of the collection box 10, when the cylinder 2 is rotated to the left or right at a small angle (such as less than ninety degrees), the left and right ends of the chute 11 are in an inclined state. At this time, after the left end of the chute 11 is higher than the right end, the impurities and dust inside the chute 11 will flow into the interior of the collection box 10 along the through hole 21, so that the impurities will not remain in the chute 11. However, when the cylinder 2 rotates at an angle greater than ninety degrees, that is, Fig. 9 As shown in the state, the impurities inside the collection box 10 can be blocked by the limiting end 22 to prevent the impurities inside the collection box 10 from flowing back into the chute 11, until the cylinder 2 is rotated from more than 90 degrees to the vertical state, that is, when the rotation angle of the cylinder 2 is less than 90 degrees, the impurities inside the chute 11 can slide into the collection box 10 through the through hole 21;

[0053] If the support plate 6 is pushed by the push ring 13 to be flush with the baffle plate 8, the pressure rod 12 is horizontal. Figure 6 Taking the support plate 6 in the middle upper part as an example, at this time, it is explained that the collection box 10 is not in a state where it can collect, but at this time, the collection box 10 at the top is in a state of tilting downward (such as Fig.13 As shown), at this time, the blocking of the through hole 21 by the limiting end 22 can prevent the dust inside the collection box 10 from flowing back into the inside of the chute 11 when the cylinder 2 rotates to more than ninety degrees.

[0054] The collecting box 10 is slidably connected to the cylinder 2 . A fixing plate 26 is provided on one side of the collecting box 10 . The fixing plate 26 is slidably connected to the cylinder 2 . A fifth spring 27 is fixedly connected between the fixing plate 26 and the inner wall of the cylinder 2 .

[0055] like Figure 2 , Figure 5-Figure 9 As shown:

[0056] The collection box 10 is blocked by the fixing plate 26 so that the collection box 10 can be located inside the collection slot 5 and will not fall. When the dust temporarily stored inside the collection box 10 needs to be cleaned, the fixing plate 26 only needs to be pushed to slide along the cylinder 2 so that the fixing plate 26 is on one side of the collection box 10 and will not block the collection box 10. The collection box 10 can then be taken out. When the collection box 10 is cleaned, it is reset and then the fixing plate 26 is released. The collection box 10 can be blocked by resetting the fifth spring 27.

[0057] The driving assembly includes a rack rod 14, which is slidably connected to the push ring 13; a third spring 15, which is fixedly connected between the two ends of the rack rod 14 and the push ring 13; a gear 16, which is fixedly connected to the side wall of the cylinder 2 and meshed with the rack rod 14; a ring gear 17, which is fixedly connected to the body 1 and meshed with the gear 16; and a rotating mechanism, which enables the cylinder 2 to be locked when it rotates around the body 1 at any angle.

[0058] The rotating mechanism includes a worm wheel 23 which is fixedly connected to the rotating shaft of the cylinder 2 ; and a worm 24 which is meshed with the worm wheel 23 and is rotationally connected to the machine body 1 .

[0059] like Figure 10-12 As shown:

[0060] When the cylinder 2 rotates from the vertical state to the left or right, taking the left state as an example:

[0061] The worm gear 23 and the cylinder body 2 are driven to rotate by rotating the worm screw 24. When the cylinder body 2 rotates, the gear 16 will mesh with the ring gear 17 and rotate, thereby driving the rack rod 14 to slide along the push ring 13. At this time, the push ring 13 will slide to the left along the cylinder body 2 and push the support plate 6 on the right to slide along the collecting groove 5 to a position flush with the baffle 8. At this time, the pressure rod 12 on the right will be horizontal. When the cylinder body 2 continues to rotate, the push ring 13 cannot move at this time. At this time, the rack rod 14 continues to slide along the push ring 13, which will continuously compress the third spring 15, thereby allowing the push ring 13 to stay.

[0062] The filter plate 3 is slidably connected to the inner wall of the cylinder 2 , and a pull rod 25 is fixedly connected to the end of the filter plate 3 , and the pull rod 25 is slidably connected to the cylinder 2 .

[0063] like Figure 4 As shown:

[0064] Before cleaning the dust inside the cylinder 2, the filter plate 3 can be vibrated inside the cylinder 2 by pulling the pull rod 25 back and forth, thereby causing the impurities attached to the filter plate 3 to fall off.
