DETAILED DESCRIPTION

[0032] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0033] As a specific embodiment, the cotton dust filtering device of the first embodiment includes a housing 1 , a filter cartridge 2 and a rotating power shaft 4 .

[0034] The housing 1 is provided with a filter chamber 11 and a water chamber 12 with a water outlet 121. The filter chamber 11 is provided with a water inlet 111 and a cotton dust outlet 112 on opposite sides thereof. It is easy to understand that there must be a partition plate between the filter chamber 11 and the water chamber 12.

[0035] The filter chamber 11 is fixedly provided with a cotton dust outlet body 113, and the cotton dust outlet body 113 has a cotton dust outlet surface (not shown in the drawings), and the top of the cotton dust outlet surface gradually decreases along the direction from the water inlet 111 to the cotton dust outlet 112. For example, the cotton dust outlet body 113 is an inclined flat plate, and one side of the flat plate is the cotton dust outlet surface; of course, the cotton dust outlet surface can also be an arc surface, etc.

[0036] The filter cartridge 2 is hollow and has a filter cartridge shaft 21 and a filter cartridge port 22 with a diameter smaller than the filter cartridge 2 at both ends, and filter holes are arranged on the side wall of the filter cartridge 2. Usually, the side wall of the filter cartridge 2 is made of a filter screen with a mesh size of 200 to 250 and has filter holes.

[0037] The filter cartridge 2 is disposed in the filter chamber 11 and can rotate in the filter chamber 11. The filter cartridge shaft 21 is directly or indirectly driven and connected to the rotary power shaft 4, so that the filter cartridge 2 can rotate. For example, the rotary power shaft 4 is an output shaft of a motor and is fixedly connected to the filter cartridge shaft 21 to achieve direct drive connection, or is connected through a transmission member 41 described later to achieve indirect drive connection.

[0038] The filter cartridge port 22 passes through the partition plate between the filter chamber 11 and the water storage chamber 12 .

[0039] The water inlet 111 and the water outlet 121 are completely lower than the top of the cotton dust outlet surface.

[0040] The filter cartridge 2 has a portion higher than the top of the cotton dust outlet surface and is in contact with or close to the cotton dust outlet body 113. For example, the cotton dust outlet body 113 is a flat plate arranged obliquely and one side of its top is in contact with the filter cartridge 2.

[0041] The working principle is that water containing cotton dust (water before filtration) enters the filter chamber 11 from the water inlet 111 and contacts the filter cartridge 2. The cotton dust in the water containing cotton dust is filtered outside the filter cartridge 2 and adheres to the side wall of the filter cartridge 2. The water containing cotton dust enters the filter cartridge 2 to form filtered water. The filtered water enters the water accumulation chamber 12 from the filter cartridge port 22 and is discharged from the water outlet 121 to the desired position.

[0042] The cotton dust attached to the side wall of the filter cartridge 2 comes into contact with the cotton dust outlet body 113 as the filter cartridge 2 rotates, so that the cotton dust is blocked by the cotton dust outlet body 113 and retained on the cotton dust outlet surface, and then discharged from the cotton dust outlet port 112, or accumulated and collected in the part of the filter chamber 11 separated by the cotton dust outlet surface and cleaned regularly.

[0043] It can be seen from the above that the cotton dust filtering device of the first embodiment can filter cotton dust and collect or discharge cotton dust. It is easy to understand that the cotton dust filtering device of the first embodiment can also filter dust such as cassava flour.

[0044] As one of the specific implementations, the partition plate between the filter chamber 11 and the water chamber 12 is hinged with at least three fixed wheels 114, and the fixed wheels 114 respectively abut against the filter cartridge opening 22. Both ends of the filter cartridge 2 are connected to the box body 1, which can ensure the stable rotation of the filter cartridge 2.

[0045] As one of the specific embodiments, it also includes a cotton dust removal brush 3 provided with a cotton dust removal brush shaft 31; the cotton dust removal brush shaft 31 has a rotating power, and the cotton dust removal brush 3 is provided with a plurality of brush bodies 39, and the brush bodies 39 are bristles, etc. The cotton dust removal brush 3 is arranged in parallel with the filter cartridge 2 (the axis lines of the two are parallel) in the filter cavity 11 and can rotate in the filter cavity 11, and the brush body 39 is in contact with or close to the filter cartridge 2 and / or the cotton dust outlet surface, such as Figure 7 As shown, the rotation direction of the bottom end of the cotton dust removal brush 3 is from the water inlet 111 to the cotton dust outlet 112. The cotton dust on the filter cartridge 2 is brushed onto the cotton dust outlet surface by the brush body 39, which is convenient for collecting and discharging cotton dust, and can also reduce or prevent the filter holes of the filter cartridge 2 from being blocked.

[0046] As one of the specific implementations, the rotational linear velocity of the distal end of the brush body 39 is greater than the rotational linear velocity of the side wall of the filter cartridge 2. Figure 7 As shown, the cotton dust removal brush 3 and the filter cartridge 2 both rotate counterclockwise, but the rotational linear velocity of the distal end of the brush body 39 is greater than the rotational linear velocity of the side wall of the filter cartridge 2. For another example, the cotton dust removal brush 3 rotates counterclockwise and the value is positive, while the filter cartridge 2 rotates clockwise and the value is negative, so the rotational linear velocity of the distal end of the brush body 39 is greater than the rotational linear velocity of the side wall of the filter cartridge 2. The distal end of the brush body 39 generates a speed difference toward the cotton dust outlet 112 relative to the part of the side wall of the filter cartridge 2 closest to it, which can ensure that the cotton dust on the filter cartridge 2 is brushed onto the cotton dust outlet surface by the brush body 39, and the reliability is high.

[0047] As one of the specific implementations, the cotton dust filtering device of the first embodiment also includes an adjustment structure 32; the adjustment structure 32 includes an adjustment slot 321 and an adjustment slider 322 that can slide along the adjustment slot 321. The adjustment slot 321 is provided on the housing 1, and both ends of the cotton dust removal brush shaft 31 are respectively hinged to the adjustment slider 322. It is easy to understand that there are at least two adjustment slots 321 and adjustment sliders 322. By sliding the adjustment slider 322 along the adjustment slot 321, the distance between the cotton dust removal brush 3 and the filter cartridge 2 can be adjusted. For example, when the brush body 39 is worn, the distance between the cotton dust removal brush 3 and the filter cartridge 2 can be reduced. Under the premise of ensuring the same cotton dust brushing effect, the service life of the cotton dust removal brush 3 can be increased.

[0048] As one of the specific implementations, the transmission member 41 is a retractable belt, such as a rubber belt, whose annular length can be stretched and extended, the adjustment groove 321 is a linear slide groove, the transmission member 41 bypasses the cotton dust removal brush shaft 31 and the rotary power shaft 4, and another transmission member 41 bypasses the cotton dust removal brush shaft 31 and the same rotary power shaft 4. The same motor can drive the filter cartridge 2 and the cotton dust removal brush 3 at the same time, which is convenient for stably controlling the speed ratio of the two and is also conducive to reducing costs.

[0049] As one of the specific implementations, the adjusting slider 322 is fixedly provided with an adjusting ear 323, and the adjusting structure 32 also includes an adjusting member 324 and a connected member 325 provided on the housing 1, and the adjusting member 324 is respectively connected to the connected member 325 and the adjusting ear 323, and the adjusting member 324 can apply force to the adjusting ear 323. For example, the adjusting member 324 is a screw and one end is hinged to the adjusting ear 323, and the other end is threadedly connected to the connected member 325, or the adjusting member 324 is a spring and both ends are respectively connected to the connected member 325 and the adjusting ear 323, so that the cotton dust brush 3 has a tendency to approach the filter cartridge 2. For the adjusting member 324 that is a screw, it is convenient to adjust the distance between the filter cartridge 2 and the cotton dust brush 3 to be fixed, and for the adjusting member 324 that is a spring, it can ensure the contact between the brush body 39 and the filter cartridge 2 and / or the housing 1.

[0050] The cotton dust filtering device of the second embodiment is as follows Figure 5 As shown by the dotted line, the tension wheel 42 also includes a movable tension wheel 42, for example, the tension wheel 42 is a sprocket and is hinged on the adjustment slider 322, and the tension wheel 42 is movable by adjusting the slider 322 and cooperating with the adjustment slot 321. The transmission member 41 is a belt-like object with a fixed length, such as a chain, and the tension wheel 42 contacts the transmission member 41 of the cotton dust removal brush shaft 31. The position movement of the tension wheel 42 can absorb the length change of the transmission member 41 caused by the position movement of the cotton dust removal brush 3, thereby ensuring that the driving of the cotton dust removal brush 3 by the rotating power shaft 4 is stable and will not slip.
