Description

Technical Field

[0001] The invention belongs to the technical field of washing water treatment, and in particular relates to a washing water filter and a filtering method thereof. Background Art

[0002] Washing water usually contains surfactants and other chemical components, which can remove dirt and grease to make items clean. Surfactants can reduce the surface tension of water and enhance the wetting and penetration ability of water, thereby making it easier to separate dirt from the surface of items and dissolve them in water. Currently, laundry shops produce a large amount of sewage when washing clothes, and the sewage is mixed with clothing lint, and laundry sewage usually needs to separate the lint in the water. Existing laundry sewage separation usually uses a filter plate to separate the lint in the water, but the filter plate gradually increases the lint when treating sewage for a long time, resulting in a decrease in the efficiency of sewage treatment. The filter plate needs to be cleaned or replaced, which increases the maintenance time of the filter plate. Therefore, a washing water filter and a filtering method thereof are proposed. Summary of the invention

[0003] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a washing water filter and a filtering method thereof, which solves the problem that the existing filter plate gradually increases the lint in sewage treatment for a long time, resulting in reduced sewage treatment efficiency, and the filter plate needs to be cleaned or replaced, which increases the maintenance time of the filter plate.

[0011] A filter plate is installed on one side of the baffle;

[0012] When one of the baffles, the filter plate and the partition plate is in a horizontal state, the cavity formed therebetween is communicated with the water inlet trough, and the sewage is filtered and processed through the filter plate.

[0013] Preferably, the inner wall of the device housing is respectively fixed with a second rubber pad and a first rubber pad, wherein the ends of the two baffles are in contact with the second rubber pad and the first rubber pad to intercept the internal flow of the device housing.

[0014] Preferably, the drainage component further comprises a drainage groove opened outside the guide pipe, and an angle between the drainage groove and the water inlet groove with the guide pipe as the central axis is greater than 90 degrees.

[0015] Preferably, the separation assembly further comprises a bellows mounted on the other side of the baffle, one end of the bellows is connected to a stabilizing plate, and the partition plate, the bellows, the baffle and the stabilizing plate form a cavity.

[0016] Preferably, when the baffle is rotated to a vertical state, the cavity formed by the partition plate, the corrugated cover, the baffle and the stabilizing plate remains in communication with the drainage groove.

[0017] Preferably, a guide rod is fixedly mounted on the bottom of the partition plate, and a limit block is fixedly mounted on the other end of the guide rod;

[0018] The water in the guide pipe enters into the cavity formed between the partition plate, the baffle plate, the corrugated cover and the stabilizing plate through the drainage groove, and the stabilizing plate moves along the guide rod.

[0019] Preferably, the limiting assembly includes a guide groove opened on the outside of the device shell, a transmission rod is slidably arranged in the guide groove, spring telescopic rods are hinged on both sides of the device shell, and the lower ends of the two spring telescopic rods are movably mounted on the two ends of the transmission rod.

[0020] Preferably, movable rings are movably sleeved on both ends of the transmission rod, and the movable rings move along the inner wall of the guide groove;

[0023] The baffle rotates, the cavity is disconnected from the drainage groove, and the stabilizing plate at the lower end is blocked by the transmission rod, which pushes the stabilizing plate to move along the guide rod to squeeze the water in the corrugated cover, and sprays it out through the water spray pipe to backwash the filter plate.

[0024] The present invention also provides a method for filtering washing water, comprising the following steps:

[0025] S1. The baffle plate contacts the second rubber pad to intercept the inside of the equipment housing. The washing sewage is injected through the top of the equipment housing. The sewage is filtered through the filter plate and enters between the baffle plate, the partition plate and the filter plate. It enters the guide pipe through the water inlet trough and is discharged. The clothing fluff mixed in the water adheres to the filter plate. The driving device is started regularly to drive the separation component to rotate 90 degrees. The next filter plate filters the sewage in the equipment housing.

[0026] S2, when the connecting pipe rotates 90 degrees, the horizontal baffle is in a vertical state, and the cavity is connected with the inside of the guide pipe through the drainage groove, while the first cavity is disconnected from the inside of the guide pipe. At this time, the horizontal filter plate filters the sewage, and the treated water enters the guide pipe. Part of the water in the guide pipe is stored in the cavity formed by the vertical partition plate, the baffle, the corrugated cover and the stabilizing plate through the drainage groove;

[0027] S3. During the rotation of the connecting pipe and the baffle, the stabilizing plate is blocked by the transmission rod.

The sprayed water backwashes the filter plate.

[0028] S4. After the bellows is completely compressed, the stabilizing plate contacts the partition plate. At this time, the stabilizing plate pushes the transmission rod to slide along the guide groove. The movable ring slides in the guide groove to reduce the wear between the transmission rod and the guide groove. During the sliding process, the spring telescopic rod is gradually stretched, and the transmission rod gradually breaks away from the contact with the stabilizing plate and the baffle. At this time, the transmission rod moves in the opposite direction and resets under the action of the spring telescopic rod.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention injects sewage into the interior of the equipment housing, and the sewage enters between the baffle plate, the partition plate and the filter plate after being filtered by the filter plate, enters the guide pipe through the water inlet groove and is discharged, while the clothing fluff mixed in the water adheres to the filter plate, and the driving device is regularly started to drive the separation component to rotate 90 degrees. During the rotation process, the next baffle plate intercepts the interior of the equipment housing, and the sewage in the equipment housing is filtered and processed by the next filter plate. In this process, the efficiency of laundry sewage filtration can be improved, and the efficiency of filter plate replacement is improved, and the maintenance time of the filter plate is reduced;

[0031] The present invention treats sewage through a horizontal filter plate. The treated water enters the guide pipe and is discharged, while part of the water is stored in the cavity formed by the partition plate, the baffle plate, the corrugated cover and the stabilizing plate through the drainage groove. During the rotation of the connecting pipe and the baffle plate, the stabilizing plate is blocked by the transmission rod. The stabilizing plate slides along the guide rod to squeeze the water in the corrugated cover. The water in the corrugated cover pushes the valve plate to compress the reset spring, and is sprayed out in all directions under the guidance of the cross. The sprayed water backwashes the filter plate, thereby extending the service life of the filter plate, reducing the workload of manual cleaning, and ensuring uninterrupted sewage treatment.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 8 As shown, the present invention provides a washing water filter, including an equipment housing 1, and also including:

[0043] A separation component 5, which is arranged inside the device housing 1 and is used for separating and processing laundry washing water;

[0044] The drainage component 3 is fixed inside the equipment housing 1, and the separation component 5 is movably sleeved outside the drainage component 3;

[0045] A driving device 2, which is installed outside the device housing 1 and is used to drive the separation component 5 to rotate 90 degrees each time;

[0046] A limit assembly 4, the limit assembly 4 is arranged on the device housing 1;

[0047] The drainage assembly 3 includes a guide pipe 31 fixed inside the equipment housing 1, and a water inlet groove 32 is provided outside the guide pipe 31;

[0048] The separation assembly 5 includes a connecting tube 51 movably sleeved on the outside of the guide tube 31, and a baffle 52 is provided in an annular array outside the connecting tube 51. The baffle 52 is communicated with the inside of the connecting tube 51, and the inside of the baffle 52 is divided into two cavities by a partition plate 54;

[0049] A filter plate 53 is installed on one side of the baffle plate 52;

[0050] When one of the baffle plates 52, the filter plate 53 and the partition plate 54 is in a horizontal state, the cavity formed therebetween is connected to the water inlet tank 32, and the sewage is filtered and processed through the filter plate 53;

[0051] The inner wall of the device housing 1 is fixedly mounted with a second rubber pad 50 and a first rubber pad 59 , respectively, wherein the ends of the two baffles 52 are in contact with the second rubber pad 50 and the first rubber pad 59 to intercept the flow inside the device housing 1 .

[0052] Laundry sewage is injected through the top of the equipment housing 1. After being filtered by the filter plate 53, the sewage enters between the baffle 52, the partition plate 54 and the filter plate 53, enters the guide pipe 31 through the water inlet groove 32 and is discharged, while the clothing fluff mixed in the water adheres to the filter plate 53. The driving device 2 is started regularly to drive the separation component 5 to rotate 90 degrees. During the rotation, the next baffle 52 contacts the second rubber pad 50 to intercept the inside of the equipment housing 1, and the sewage in the equipment housing 1 is filtered and processed by the next filter plate 53. This cycle reduces the replacement and cleaning time of the filter plate 53, and can improve the efficiency of laundry sewage filtration.

[0053] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the drainage assembly 3 further includes a drainage groove 33 disposed outside the guide pipe 31, and the angle between the drainage groove 33 and the water inlet groove 32 with the guide pipe 31 as the central axis is greater than 90 degrees;

[0054] The separation assembly 5 further includes a bellows 55 mounted on the other side of the baffle 52, one end of the bellows 55 is connected to a stabilizing plate 56, and the partition plate 54, the bellows 55, the baffle 52 and the stabilizing plate 56 form a cavity;

[0055] When the baffle 52 rotates to a vertical state, the cavity formed by the partition plate 54, the corrugated cover 55, the baffle 52 and the stabilizing plate 56 is connected to the drainage groove 33;

[0056] A guide rod 57 is fixedly mounted on the bottom of the partition plate 54, and a limit block 58 is fixedly mounted on the other end of the guide rod 57;

[0057] The water in the guide pipe 31 enters into the cavity formed between the partition plate 54 , the baffle plate 52 , the bellows 55 and the stabilizing plate 56 through the drainage groove 33 , and the stabilizing plate 56 moves along the guide rod 57 .

[0058] The equipment housing 1 is intercepted by the horizontal baffle 52, and the horizontal filter plate 53 filters the sewage. When the connecting pipe 51 rotates 90 degrees, the horizontal baffle 52 is in a vertical state, and the cavity is connected with the inside of the guide pipe 31 through the drainage groove 33, and the first cavity is disconnected from the guide pipe 31. At this time, the horizontal filter plate 53 filters the sewage, and the treated water enters the guide pipe 31. The water in the guide pipe 31 enters the cavity formed by the vertical partition plate 54, the baffle 52, the corrugated cover 55 and the stabilizing plate 56 through the drainage groove 33 for storage. As the corrugated cover 55 gradually expands, the stabilizing plate 56 slides along the guide rod 57 to improve the stability of the corrugated cover 55.

[0059] like Figure 3 and Figure 8As shown, the limit assembly 4 includes a guide groove 43 opened outside the device housing 1, a transmission rod 45 is slidably arranged in the guide groove 43, and spring telescopic rods 41 are hinged on both sides of the device housing 1, and the lower ends of the two spring telescopic rods 41 are movably sleeved with the two ends of the transmission rod 45;

[0060] Both ends of the transmission rod 45 are movably sleeved with movable rings 44, and the movable rings 44 move along the inner wall of the guide groove 43;

[0061] The transmission rod 45 is in contact with the stabilizing plate 56 in the vertical state;

[0062] The partition plate 54 is provided with a water spray pipe 511 in array, and a limit ring 516 and a cross 512 are fixedly installed inside the water spray pipe 511. A stabilizing rod 513 is movably sleeved on the cross 512. A valve plate 515 is fixedly installed at the bottom of the stabilizing rod 513 to block the limit ring 516. A return spring 514 is provided between the valve plate 515 and the cross 512.

[0063] The baffle 52 rotates, the cavity is disconnected from the drain groove 33, and the lower end stabilizing plate 56 is blocked by the transmission rod 45, pushing the stabilizing plate 56 to move along the guide rod 57 to squeeze the water in the corrugated cover 55, and spraying it out through the water spray pipe 511 to backwash the filter plate 53.

[0064] The sewage is treated by the horizontal filter plate 53, and the treated water enters the guide pipe 31 for discharge, while part of the water is stored in the cavity formed by the partition plate 54, the baffle plate 52, the bellows 55 and the stabilizing plate 56 through the drainage groove 33. During the rotation of the connecting pipe 51 and the baffle plate 52, the stabilizing plate 56 is blocked by the transmission rod 45, and the stabilizing plate 56 slides along the guide rod 57 to squeeze the water in the bellows 55. The water in the bellows 55 pushes the valve plate 515 to compress the return spring 514, and is sprayed out in all directions under the guidance of the cross 512, so as to ensure that the filter plate 53 is fully flushed. The sprayed water backwashes the filter plate 53, thereby extending the service life of the filter plate 53, reducing the workload of manual cleaning, and ensuring uninterrupted sewage treatment. At the same time, the water sprayed by the multiple water spray pipes 511 can achieve the backwashing effect of the filter plate 53, avoiding the residual clothing lint on the filter plate 53;

[0065] After the bellows 55 is completely compressed, the stabilizing plate 56 contacts the partition plate 54. At this time, the stabilizing plate 56 pushes the transmission rod 45 to slide along the guide groove 43, and the wear between the transmission rod 45 and the guide groove 43 is reduced by sliding the movable ring 44 in the guide groove 43. During the sliding process, the spring telescopic rod 41 is gradually stretched, and the transmission rod 45 gradually breaks away from the contact with the stabilizing plate 56 and the baffle 52. At this time, the transmission rod 45 moves in the opposite direction and resets under the action of the spring telescopic rod 41, and the cycle can be worked.

[0066] The present invention also provides a method for filtering washing water, comprising the following steps:

[0067] S1. The baffle 52 contacts the second rubber pad 50 to intercept the inside of the equipment housing 1. The laundry sewage is injected through the top of the equipment housing 1. The sewage is filtered by the filter plate 53 and enters between the baffle 52, the partition plate 54 and the filter plate 53. It enters the guide pipe 31 through the water inlet groove 32 and is discharged. The clothing fluff mixed in the water adheres to the filter plate 53. The driving device 2 is started regularly to drive the separation component 5 to rotate 90 degrees. The next filter plate 53 filters the sewage in the equipment housing 1.

[0068] S2. When the connecting pipe 51 rotates 90 degrees, the horizontal baffle 52 is in a vertical state, and the cavity is connected with the inside of the guide pipe 31 through the drainage groove 33, while the first cavity is disconnected from the inside of the guide pipe 31. At this time, the horizontal filter plate 53 filters the sewage, and the treated water enters the guide pipe 31. Part of the water in the guide pipe 31 is stored in the cavity formed by the vertical partition plate 54, the baffle 52, the corrugated cover 55 and the stabilizing plate 56 through the drainage groove 33;

[0069] S3, during the rotation of the connecting pipe 51 and the baffle 52, the stabilizing plate 56 is blocked by the transmission rod 45, and the stabilizing plate 56 slides along the guide rod 57 to squeeze the water in the bellows 55, and the water in the bellows 55 pushes the valve plate 515 to compress the return spring 514, and the water is sprayed out in all directions under the guidance of the cross 512, so as to ensure that the filter plate 53 is fully flushed, and the sprayed water performs a backwashing treatment on the filter plate 53;

[0070] S4. After the bellows 55 is completely compressed, the stabilizing plate 56 contacts the partition plate 54. At this time, the stabilizing plate 56 pushes the transmission rod 45 to slide along the guide groove 43. The movable ring 44 slides in the guide groove 43 to reduce the wear between the transmission rod 45 and the guide groove 43. During the sliding process, the spring telescopic rod 41 is gradually stretched, and the transmission rod 45 gradually breaks away from the contact with the stabilizing plate 56 and the baffle 52. At this time, the transmission rod 45 moves in the opposite direction and resets under the action of the spring telescopic rod 41.
