Description

Technical Field

[0001] The present invention relates to the field of environmental protection, and specifically to a cyclone backwashing filter and its backwashing and filtering method. Background Art

[0002] The cyclone backwashing filter is mainly used for filtering and treating wastewater;

[0003] During filtration, when wastewater enters from the water inlet, the polymer filter media adsorbs and intercepts oil and suspended particles in the water with a large specific surface area and porosity.

[0004] It fully exerts the deep sewage interception ability of the filter media, and has the characteristics of small head loss, high filtration rate, large sewage interception ability, and the filter layer will not cake;

[0005] In order to extend the service life of the filter media of the filter, a backwashing method is generally designed to clean the filter media. Even when the cleaning of the filter media is completed, the filter media needs to be replaced after long-term use. The traditional replacement method is basically the unified replacement of multiple layers of filter media, and the housing needs to be disassembled when replacing the filter media, and then the replacement of the filter media is completed;

[0006] This replacement method has the following problems:

[0007] 1. The filtered impurities between the over-layer filter media are different. Since the upper-layer filter media filters impurities for the first time and has the most attached impurities, and the impurities decrease layer by layer. When the upper-layer filter media needs to be replaced, the second and third layers can still be used. In the case of all replacements, it causes waste of filter media;

[0008] 2. Disassembling the housing to replace the filter media is not convenient enough. Summary of the Invention

[0051] Filtering method: Sewage is discharged from the inlet passage into the housing, filtered by multiple layers of filter beads, and then discharged through the drainage passage;

[0052] Backwashing method includes:

[0053] Step 1: Connect the gas source and the water source through the medium inlet passage. During backwashing, the water source and the gas source alternately pass through the upper cleaning member and the lower cleaning member to complete the cleaning of the filter beads, and at the same time, the arcuate cleaning member completes the cleaning of the lower surface of the arcuate plate;

[0054] During cleaning, the upper cleaning member and the lower cleaning member rotate in opposite directions, and the water source and the gas source are alternately connected;

[0063] When new filter beads are put into the lower backwash part, the adjusting motor drives the adjusting arm to swing, drives the adjusting shaft to move, and drives the adjusting disk to rotate 90 degrees. At this time, the feeding adjustment hole corresponds to the feeding outlet hole, and new filter beads are poured into the material changing inlet hole. They flow to the material changing outlet through the gap between the material changing shaft and the turning drum, and are discharged into the lower backwash part, completing the replacement of the filter beads.

[0064] After the replacement is completed, the adjusting cylinder resets. At this time, the adjusting cylinder descends and contacts the turning roller, and at this time, the flow holes and the feeding holes are closed.

[0065] Beneficial effects: The present invention discloses a cyclone backwashing filter and its backwashing and filtering method. When the filtering beads need to be replaced in the present invention, the adjusting cylinder is driven by the adjusting driving member to work, so that the adjusting hole groups on the adjusting cylinder correspond to the required holes of the flow hole groups. Then, the feeding driving member drives the feeding shaft to rotate, and the filtering beads in the upper backwashing member are lifted out of the housing through the feeding propeller, the filtering beads in the middle backwashing member are lifted into the upper backwashing member, and the filtering beads in the lower backwashing member are lifted into the middle backwashing member.

[0110] A water inlet channel 11 is provided at the top of the housing 1, and a discharge channel and a sewage discharge channel 13 are provided at the bottom.

[0111] As shown in the appendix Figures 5-7 As shown, the lifting unit 3 includes:

[0115] When the filter beads of the present invention need to be replaced, the adjusting driving member 34 drives the adjusting cylinder 32 to work, so that the adjusting hole group 321 on the adjusting cylinder 32 corresponds to the holes required by the flow hole group. Then, the material changing driving member 36 drives the material changing shaft 33 to rotate, and the filter beads in the upper layer of the backwashing member are lifted outside the housing 1 through the material changing propeller 331. The filter beads in the middle layer of the backwashing member are lifted into the upper layer of the backwashing member, and the filter beads in the lower layer of the backwashing member are lifted into the middle layer of the backwashing member. At the same time, new filter beads are placed in the lower layer of the backwashing member;

[0116] Through this design, the lower layer of filter beads is replaced to the middle layer, the middle layer of filter beads is replaced to the upper layer, and new filter beads are placed in the lower layer, avoiding the waste of filter beads. At the same time, there is no need to disassemble the housing 1, making the replacement of filter beads more convenient.

[0117] At the same time, by designing the turning drum 31, the filter beads at the bottom of the same layer are turned to the upper part, which is convenient for backwashing and avoids the situation of uneven and incomplete cleaning.

[0132] An adjusting cylinder 344 is connected to the turning drum 31, a ball is embedded at the output end of the adjusting cylinder 344, and the ball abuts against the adjusting disk 322;

[0133] A material-changing inlet hole communicating between the turnover drum 31 and the material-changing shaft 33 is formed at the top of the adjusting cylinder 32. The material-changing inlet hole can cooperate with a material-changing hopper or a funnel to work.

[0134] The adjusting cylinder 344 can be a pneumatic cylinder. By designing ball bearings, excessive frictional force is avoided, which may affect the rotation of the adjusting cylinder 32.

[0135] The material-changing driving member 36 includes:

[0136] A material-changing motor 361 is connected to the turnover drum 31, and a material-changing driving gear 362 is provided at the output end of the material-changing motor 361;

[0137] A material-changing input gear 332 is sleeved on the material-changing shaft 33 and meshes with the material-changing driving gear 362.

[0138] A backwashing and filtering method includes:

[0139] Filtering method: Sewage is discharged into the housing 1 from the water inlet channel 11, filtered by multiple layers of filtering beads, and then discharged through the drain channel 12;

[0140] Backwashing method includes:

[0141] Step 1: Connect a gas source and a water source through the medium inlet channel 25. During backwashing, the water source and the gas source alternately pass through the upper cleaning member 21 and the lower cleaning member 22 to complete the cleaning of the filtering beads, and at the same time, the bow-shaped cleaning member 23 completes the cleaning of the lower surface of the bow-shaped plate 24;

[0142] During cleaning, the upper cleaning member 21 and the lower cleaning member 22 rotate in opposite directions, and the water source and the gas source are alternately connected;

[0143] The cleaned sewage is discharged through the sewage discharge channel 13;

[0144] The water source or the gas source enters the cleaning cavity 211A through the flow cavity 14 and is finally sprayed out through the cleaning nozzle 212 to complete the cleaning work of the filtering beads;

[0145] The reverse rotation of the upper cleaning member 21 and the lower cleaning member 22 is driven by a reverse driving motor to drive the reverse rotation of the upper bevel gear ring 21A and the lower bevel gear ring 22A;

[0146] By alternately connecting the water source and the gas source, and the upper cleaning member 21 and the lower cleaning member 22 rotate in opposite directions, simulating the manual kneading process, the work of cleaning the filtering beads is achieved;

[0147] The cleaning of the lower surface of the bow-shaped plate 24 is completed by the bow-shaped cleaning member 23, avoiding secondary pollution of the cleaning caused by remaining impurities.

[0148] Step 2: During the cleaning process, the tumbling drive 35 drives the hair roller to rotate, which drives the propeller group to rotate, and rolls the bottom filter beads on the same layer to the upper layer;

[0149] During operation, the tumbling motor 351 drives the tumbling drive gear 352 to rotate, drives the tumbling input gear 353 to rotate, drives the tumbling drum 31 to rotate, drives the upper propeller 311, the middle propeller 312 and the lower propeller 313 to rotate, and completes the tumbling of the filter beads at the corresponding layers;

[0150] This tumbling avoids the situation where the filter beads at the bottom of the same layer are not cleaned properly;

[0151] Step 3: When the filter beads need to be replaced, the adjusting drive 34 drives the adjusting cylinder 32 to work, so that the adjusting hole group 321 on the adjusting cylinder 32 corresponds to the holes required by the flow hole group, and then the material changing drive 36 drives the material changing shaft 33 to rotate, and the filter beads in the upper backwash part are lifted to the outside of the housing 1 through the material changing propeller 331, and the filter beads in the middle backwash part are lifted to the upper backwash part, and the filter beads in the lower backwash part are lifted to the middle backwash part, and new filter beads are placed in the lower backwash part;

[0152] The traditional replacement method is to replace all of them by disassembling the shell 1. However, since the upper filter beads filter impurities for the first time, the upper filter beads have the most impurities, and the impurities decrease layer by layer. When the upper filter beads need to be replaced, the middle and lower layers can still be used.
