DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1, as Figure 1 and Figure 2 As shown, a Roots blower with a filtering structure includes a base 1, a main motor 2 is fixedly mounted on the upper end of the base 1, a Roots blower body 3 is fixedly mounted on the upper end of the base 1, the Roots blower body 3 is connected to the output end of the main motor 2 through a pulley group, an air intake pipe 4 is fixedly connected to the upper end of the Roots blower body 3, an outer shell 5 is fixedly connected to one end of the air intake pipe 4, a vibration separation component 6 is commonly provided on the front and lower ends of the inner surface of the outer shell 5, and a wet filter component 7 is provided on the rear end of the inner surface of the outer shell 5.

[0022] During the implementation of this embodiment, the main motor 2 is started, so that the output end of the main motor 2 drives the Roots blower body 3 to run through the pulley group transmission. During the operation, the Roots blower body 3 draws air into the inner cavity of the Roots blower body 3 through the air intake pipe 4. During the air suction process, the air is preliminarily dry-filtered by the vibration separation component 6 in the shell 5, and the dust and debris are vibrated and cleaned during the filtering process. Then, the air is wet-filtered again by the wet filter component 7, so that the dust particles with smaller particles in the air are captured, so that the amount of dust attached to the Roots blower body 3 can be reduced during the operation, so that the Roots blower body 3 can always maintain a constant speed during the rotation process, while providing a stable air volume, reducing the power output by the main motor 2, reducing the working pressure of the main motor 2, thereby achieving energy saving.

[0023] The Roots blower body 3 mentioned above is a mature blower device in the prior art. In this solution, its function of generating wind is utilized, and its internal structure, principle and connection method are not further described.

[0024] Specifically, in order to achieve dry filtration and cleaning of air, refer to Figure 4 , Figure 5 and Figure 6 In this embodiment, the vibration separation assembly 6 includes a water tank 61 fixedly connected to the lower end of the outer shell 5 and the upper end of the base 1, a mounting plate 64 is fixedly connected to the inner surface of the outer shell 5, a plurality of bag filters 65 are fixedly connected to the inner surface of the mounting plate 64 at linear and equidistant distributions, a separation mechanism 62 is provided on the inner surface of the outer shell 5, and a vibration mechanism 63 is provided on the inner surface of the outer shell 5 below the bag filter 65.

[0025] For further information, see Figure 4 In this embodiment, the partition mechanism 62 includes a partition 1 621 fixedly connected to the inner surface of the outer shell 5, a partition 2 622 is fixedly connected to the inner surface of the outer shell 5 behind the partition 1 621, and a partition 3 623 is fixedly connected to the inner surface of the outer shell 5 behind the partition 2 622.

[0026] During the implementation process, the Roots blower body 3 will suck air into the shell 5 through the rectangular hole at the bottom of the front end of the shell 5 during operation. The air entering the shell 5 will first pass through the bag filter 65, which will filter large particles of dust in the air and retain the filtered dust on the outer surface of the bag filter 65. At the same time, the air continues to move upward through the inner cavity of the bag filter 65. Under the action of partition one 621 and partition two 622, the air after dry filtration is guided to the space formed by partition two 622 and partition three 623. Large particles of dust and debris in the air can be filtered to reduce the dust concentration in the air. Dry filtration can first remove large particles and dust in the air, reduce the burden on wet filtration, maintain the wet filtration effect, and thus improve the overall filtration efficiency.

[0027] The bag filter 65 mentioned above is a mature filtering technology means and equipment in the prior art. In this solution, its function of filtering dust and debris in the air is utilized, and its internal structure and principle are not further explained.

[0028] For further information, see Figure 5 and Figure 6 In this embodiment, the vibration mechanism 63 includes a servo motor 631 fixedly connected to the right front end of the shell 5, the output end of the servo motor 631 is fixedly connected to a reciprocating rod 632 rotatably connected to the shell 5 and the partition 621 through a coupling, the outer surface of the reciprocating rod 632 is slidably connected to an L-shaped plate 633 tightly attached to the right inner surface of the shell 5, the upper end of the L-shaped plate 633 is linearly and equidistantly fixedly connected to three balls 634, the front end of the partition 621 is linearly and equidistantly fixedly connected to three triangular plates 635, the inner surfaces of the three triangular plates 635 are linearly and equidistantly fixedly connected to a plurality of round rods 636, the lower ends of the plurality of round rods 636 are fixedly connected to a hemispherical block 637, the outer surfaces of the plurality of round rods 636 are sleeved with a spring 638, and the two ends of the plurality of springs 638 are respectively fixedly connected to the upper end of the hemispherical block 637 and the lower end of the triangular plate 635.

[0029] As can be seen from the above, when filtering the air, the servo motor 631 is started, so that the output end of the servo motor 631 drives the reciprocating rod 1 632 to rotate through the coupling. Since the reciprocating rod 1 632 and the L-shaped plate 633 are in sliding connection, the L-shaped plate 633 can reciprocate back and forth on the outer surface of the reciprocating rod 1 632, so that the ball 634 on the L-shaped plate 633 can squeeze the hemispherical block 637 during the movement path, so that the hemispherical block 637 can push the round rod 636 to move upward. , pushing the lower end of the bag filter 65, while the spring 1 638 is in a compressed state, when the ball 634 is away from the outer surface of the hemispherical block 637, the hemispherical block 637 will be reset under the compression reaction force of the spring 1 638, so that the bag filter 65 can be reset, and then the dust attached to the outer surface of the bag filter 65 can be cleaned. Cleaning the dust can ensure that the bag maintains efficient filtering performance, thereby continuously providing clean air, reducing the wear of the bag, extending its service life, and reducing replacement costs.

[0030] Embodiment 2: Based on Embodiment 1, this embodiment adds a wet filter component 7 for wet filtering the air filtered by the bag filter 65, so as to achieve the purpose of wet filtering the air filtered by the bag filter 65.

[0031] Specifically, in order to perform wet filtration on the air filtered by the bag filter 65, refer to Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 In this embodiment, the wet filter assembly 7 includes a circular hole plate 1 71 which is fixedly connected to one end of the partition plate 2 622 and the partition plate 3 623 which are close to each other, a liquid membrane mechanism 72 is arranged on the upper end of the circular hole plate 1 71, a sealing mechanism 73 is arranged below the liquid membrane mechanism 72 at one end of the partition plate 2 622 and the partition plate 3 623 which are close to each other, a squeezing mechanism 74 is arranged on the upper part of the rear end of the partition plate 3 623, and a drying mechanism 75 is arranged on the lower part of the rear end of the partition plate 3 623.

[0032] For further information, see Figure 5 and Figure 7In this embodiment, the liquid film mechanism 72 includes a rectangular frame 721 fixedly connected to the middle part of the upper end of the circular hole plate 71, a slope block 722 is slidably connected to the inner surface of the rectangular frame 721, a concave frame 723 is fixedly connected to the upper end of the slope block 722, the front end of the partition plate 2 622 passes through and extends to the rear end of the partition plate 3 623 and is rotatably connected to the reciprocating rod 2 724 slidably connected to the concave frame 723, a transmission mechanism 725 is fixedly connected to the front of the outer surface of the reciprocating rod 2 724 and the rear of the outer surface of the reciprocating rod 1 632, a spray pipe 727 is fixedly connected to the upper inner surface of the water tank 61 and extends to the inner surface of the concave frame 723, and a water pump 726 is fixedly connected to the lower end of the spray pipe 727.

[0033] For further information, see Figure 5 and Figure 8 In this embodiment, the blocking mechanism 73 includes a fixed T-shaped plate 731 which is fixedly connected to one end of the partition plate 2 622 and the partition plate 3 623 which are close to each other. A plurality of cylinders 732 are symmetrically fixedly connected to the inner surface of the fixed T-shaped plate 731. The upper ends of the plurality of cylinders 732 are fixedly connected to corrugated circular hole tubes 733. The upper ends of the corrugated circular hole tubes 733 on the same side are commonly fixedly connected to a blocking plate 734. The middle parts of the upper ends of the two blocking plates 734 are fixedly connected to connecting rods 736 which are slidably connected to the inner surface of the circular hole plate 1 71. The upper ends of the two connecting rods 736 are fixedly connected to extrusion plates 735. The outer surfaces of the two connecting rods 736 are sleeved with springs 2 737. The two ends of the two springs 2 737 are respectively fixedly connected to the lower end of the circular hole plate 1 71 and the upper end of the blocking plate 734.

[0034] During the implementation process, the air filtered by the bag filter 65 will enter the space formed by the partition two 622 and the partition three 623, and then the reciprocating rod two 724 will be driven to rotate under the cooperation of the rotation of the reciprocating rod one 632 and the transmission mechanism 725. Since the concave frame 723 and the reciprocating rod two 724 are slidably connected, the concave frame 723 moves back and forth, and at the same time drives the inclined surface block 722 to slide back and forth on the inner surface of the rectangular frame 721. At this time, the water pump 726 is started to allow the water pump 726 to draw water from the water tank 61 into the spray pipe 727, so that the spray pipe 727 can spray water on the circular hole plate one 71 and form a liquid film on the circular hole plate one 71. At the same time, when the inclined surface block 722 slides on the inner surface of the rectangular frame 721, it will squeeze the squeezing plate 735, so that the squeezing plate 735 pushes the connecting rod 721 downward. The sealing plate 734 on the connecting rod 736 compresses the corrugated circular hole tube 733 so that the corrugated circular hole tube 733 closes the upper end of the cylinder 732, so that air cannot enter before the liquid film is formed, providing sufficient time for the formation of the liquid film. When the inclined block 722 moves away from the extrusion plate 735 on one side, it will squeeze the extrusion plate 735 on the other side. The upper end of the cylinder 732 on this side is opened under the compression reaction force of the spring 2 737, and the cylinder 732 on the other side is closed, so that air enters and breaks the liquid film, which can efficiently capture dust in the air. The surface area of ​​the liquid film is large, and the gas-liquid contact area is increased, making it easier for dust particles to contact and be captured by the liquid film. At the same time, the wettability of the liquid film and the use of a wetting agent can significantly improve the capture efficiency of fine particles, including those tiny dust particles.

[0035] The corrugated round hole tube 733 mentioned above is made of soft material.

[0036] The left and right ends of the concave frame 723 are in close contact with the inner surface of the housing 5 .

[0037] The transmission mechanism 725 mentioned above is composed of two pulleys and a belt.

[0038] For further information, see Figure 5 and Fig. 9 In this embodiment, the squeezing mechanism 74 includes a partition plate 4 741 fixedly connected to the rear end of the partition plate 3 623 and the inner surface of the shell 5, the upper end of the partition plate 4 741 is fixedly connected to a circular hole plate 2 743 fixedly connected to the upper part of the inner surface of the shell 5, a sponge block 744 is pasted to the rear end of the circular hole plate 2 743, the rear end of the reciprocating rod 2 724 is fixedly connected to a reciprocating rod 3 742 rotatably connected to the partition plate 4 741, and a square plate 745 is slidably connected to the outer surface of the reciprocating rod 3 742.

[0039] For further information, see Figure 5 and Fig.10In this embodiment, the drying mechanism 75 includes a partition plate 5 751 fixedly connected to the lower end of the partition plate 4 741 and the rear end of the partition plate 3 623, a heating plate 752 is fixedly installed on the right part of the inner surface of the partition plate 5 751, and a plurality of blocking plates 753 are fixedly connected to the left end of the partition plate 5 751 in a linear and equidistant staggered manner.

[0040] During the implementation process, the air after wet filtration enters the sponge block 744 through the circular hole plate 2 743 under the action of the partition 3 623. Since the sponge block 744 has a porous structure, the sponge block 744 can effectively capture moisture in the air. At the same time, the rotation of the reciprocating rod 2 724 will drive the reciprocating rod 3 742 to rotate. Since the reciprocating rod 3 742 and the square plate 745 are slidably connected, the square plate 745 can move back and forth to squeeze the water retained by the sponge block 744, so that the sponge block 744 can continuously capture moisture and reduce the humidity of the air.

[0041] Secondly, the air enters the space formed by the blocking plate 753 under the action of the partition four 741 and the partition five 751, and takes an S-shaped path under the action of the blocking plate 753, and the air is dried under the action of the heating plate 752 to reduce the humidity of the air, thereby preventing the filtered air with high humidity from entering the inner cavity of the Roots blower body 3, causing damage to the internal parts of the Roots blower body 3. At the same time, the air after wet filtration can reduce the temperature of the air when the humidity does not affect the internal parts of the Roots blower body 3, so as to facilitate use by users.

[0042] The sponge block 744 mentioned above is a porous structure, which can capture moisture in the air without affecting the air flow rate in this solution.

[0043] The reciprocating rod 1 632, L-shaped plate 633, reciprocating rod 2 724, concave frame 723, reciprocating rod 3 742 and square plate 745 mentioned above, in pairs, constitute a mature ball screw mechanism in the prior art.

[0044] For further information, see Figure 4 , Figure 5 and Fig. 9 In this embodiment, the sewage discharge mechanism 76 includes a connecting pipe 1 761 that penetrates the lower part of the inner surface of the partition 4 741 and extends to the front end of the partition 1 621 and is fixedly connected, the upper end of the fixed T-shaped plate 731 penetrates symmetrically front and back and extends to the inner surface of the connecting pipe 1 761 and is fixedly connected with a connecting pipe 2 762, the front side of the lower part of the inner surface of the outer shell 5 penetrates and extends to the upper part of the inner surface of the water tank 61 and is fixedly connected with a return pipe 763, a filter screen 764 is fixedly installed on the inner surface of the water tank 61, and a solenoid valve 765 is fixedly installed at the front end of the connecting pipe 1 761.

[0045] During the implementation process, the water squeezed out by the squeezing mechanism 74 will fall on the inner surface of the partition four 741 and enter the connecting tube one 761. The water filtered by the liquid membrane mechanism 72 will enter the connecting tube one 761 through the two connecting tubes two 762. Then, the front end of the connecting tube one 761 will be opened by the solenoid valve 765. The accumulated water will enter the lower front side of the inner surface of the outer shell 5 to flush the dust cleaned by the vibration mechanism 63, and enter the water tank 61 through the reflux pipe 763. It will be filtered under the action of the filter net 764 and then used again.

[0046] The solenoid valve 765 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its function of controlling whether the front end of the connecting pipe 761 is open is utilized, and its internal structure, connection method and principle are not further explained.

[0047] Working process: when in use, air is sucked into the shell 5 through the rectangular hole at the front end of the shell 5, and then the air is dry-filtered under the action of the bag filter 65, and during the filtering process, the dust retained on the outer surface of the bag filter 65 is cleaned by the vibration mechanism 63. The air after dry filtration will be wet-filtered under the cooperation of the liquid membrane mechanism 72 and the sealing mechanism 73, and the filtered air will be dried under the cooperation of the extrusion mechanism 74 and the drying mechanism 75. At the same time, the sewage in the wet filtration process will flow back under the action of the sewage discharge mechanism 76 to flush the dust cleaned by the vibration mechanism 63, and then enter the water tank 61 for recycling.
