Description

Technical Field

[0001] The invention relates to the technical field of rural water purification, in particular to an integrated rural drinking water purification device. Background Art

[0002] In some remote mountainous rural areas, due to the distance from the urban area, the cost of laying pipelines to the rural areas is too high, so it is impossible to provide unified water supply. In order to ensure the daily drinking water safety of local villagers, it is necessary to purify the local drinking water sources in the rural areas;

[0003] Existing rural drinking water purification devices often purify water through ultrafiltration membranes, and impurities in the water often remain in the purification device. Therefore, personnel are required to perform regular maintenance, such as cleaning the ultrafiltration membrane and cleaning the filtrate in the purification device. However, there is often a lack of personnel in this area in rural areas, so the purification device is often not cleaned for a long time, resulting in a decrease in the total water output and a decrease in purification efficiency, which may eventually cause damage to the purification device. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides an integrated rural drinking water purification device.

A accommodating cavity is arranged in the annular notch, and the accommodating cavity is connected with the flushing port. The rotating disk blocks the opening of the accommodating cavity, and a water outlet is provided on the rotating disk. When the water inlet shaft rotates, the water outlet can be aligned with the accommodating cavity, and water flows downward from the flushing port. An annular magnetic block is also provided on the water inlet shaft, and a magnetic switch plate is elastically slidably arranged on the water outlet end. When the annular magnetic block passes by, the magnetic switch plate can be magnetically adsorbed to close the water outlet end. The annular magnetic block is symmetrical about the water outlet. Therefore, when flushing water is performed at the flushing port, the water outlet end is closed and the ultrafiltration membrane module stops working.

[0006] Its beneficial effect is that when the water purification equipment is running, the ultrafiltration module in the water inlet equipment can be automatically shut down and flushed alternately, thereby reducing the attachment on the ultrafiltration module, improving the filtering effect of the ultrafiltration module, and ensuring that the equipment can operate normally for a long time.

When the water inlet shaft rotates, the independent N or S pole can pass through the annular magnetic block area, thereby causing the vibration frame to move back and forth in the radial direction.

[0011] The beneficial effect is that the membrane filaments on the ultrafiltration module are vibrated back and forth during the process of alternately stopping the ultrafiltration module for flushing, so that the attachments on the membrane filaments fall off quickly, further improving the flushing effect.

The water outlet end 231 is connected, and water is injected into the filter barrel 1 to increase the water pressure in the filter barrel 1. The water in the filter barrel 1 enters the internal channel of the membrane wire 232 from the outside of the membrane wire 232 through the water pressure, and then converges to the water outlet end 231, and is transported outward from the water outlet end 231, while impurities and bacteria are blocked on the outer wall of the membrane wire 232. A plurality of flushing ports 233 are also provided on the lower end surface of the ultrafiltration membrane module 23, and the plurality of flushing ports 233 are distributed around the membrane wire 232. An annular notch 234 is also provided on the inner ring of the ultrafiltration membrane module 23, and an open accommodating cavity 2341 is provided on the annular notch 234. The accommodating cavity 2341 is connected to the plurality of flushing ports 233, and the accommodating cavity 2341 on each ultrafiltration membrane module 23 is independent, with only one opening toward the center of the circle, and all the annular notches 234 on the ultrafiltration module assembly 21 form a circular notch.

[0026] The water inlet shaft 22 is hollow in design and is used to supply water to the filter barrel 1. The lower end of the water inlet shaft 22 exceeds the bottom surface of the filter barrel 1 and is rotatably arranged on the bottom end of the filter barrel 1. A motor is arranged on the lower end surface of the bottom end of the filter barrel 1, and the motor is connected to the water inlet shaft 22 through a belt. The rotation of the motor drives the water inlet shaft 22 to rotate. A rotating disk 221 is arranged on the water inlet shaft 22, and the rotating disk 221 is rotatably arranged on a circular groove formed by the annular groove 234, and the peripheral wall of the rotating disk 221 closes the front end opening of the accommodating cavity 2341. A water outlet 2211 is arranged on the rotating disk 221, wherein when the water inlet shaft 22 rotates, the water outlet 2211 can be aligned with several independent accommodating cavities 2341 on the ultrafiltration module assembly 21 at one time, and the bottom end of the water inlet shaft 22 is connected to the external water supply pipe through a pipeline, so that water flows downward from the flushing port 233, thereby flushing the membrane filament 232.

[0027] An annular magnetic block 223 is also provided at the upper end of the water inlet shaft 22, and a sliding cavity is opened on the cross-section of the water outlet end 231, and a magnetic switch plate 2311 is slidably arranged in the sliding cavity, and a first elastic member is provided at the rear end of the magnetic switch plate 2311 to contact with the water outlet end 231 so that the water outlet end 231 is in a smooth state in the initial state, and the annular magnetic block 223 is guided and slidably arranged in the annular track 211, and the magnetic pole of the annular magnetic block 223 is consistent with the magnetic pole of the magnetic switch plate 2311, so when the annular magnetic block 223 passes through the magnetic switch plate 2311, it can push the magnetic switch plate 2311 to move toward the water outlet end 231, thereby blocking the channel of the water outlet end 231, so that the water outlet end 231 is in a closed state, that is, the ultrafiltration membrane module 23 here no longer works.

[0028] The arc segment angle of the annular magnetic block 223 is consistent with the arc segment angle of the ultrafiltration membrane module 23, and the annular magnetic block 223 is symmetrical about the water outlet 2211. Therefore, when the water outlet 2211 is aligned with the accommodating cavity 2341 of the ultrafiltration membrane module 23, the annular magnetic block 223 is already located at the front end of the magnetic switch plate 2311, thereby blocking the water outlet 231. The ultrafiltration membrane module 23 at this position stops working and switches to flushing. The water flows downward from the flushing port 233, thereby flushing the membrane filament 232.

[0029] The ultrafiltration membrane assembly 21 is provided with an annular block 212, and the vibration module 3 includes a vibration frame 31. The vibration frame 31 is provided with a guide shaft 313, which is slidably arranged on the annular block 212 through the guide shaft 313, and a second elastic member 314 is sleeved on the guide shaft 313, and the two ends of the second elastic member 314 respectively touch the vibration frame 31 and the annular block 212, and the vibration frame 31 is provided with a plurality of ring pieces 311, the ring pieces 311 are arc-shaped, and the arc angle is smaller than the arc angle of the ultrafiltration membrane module 23, and the ring pieces 311 are distributed at the front and rear positions of the membrane wire 232 below the ultrafiltration membrane module 23, and the vibration frame 31 can move forward and backward along the radius line of the ultrafiltration membrane module 23, so that the ring pieces 311 touch the membrane wire 232 in the front and rear direction, so that the membrane wire 232 moves forward and backward together, so that the attachments attached to the membrane wire 232 fall downward.

[0030] A vibration module 3 is arranged below each ultrafiltration membrane module 23, and an annular magnetic block area 312 is arranged on the vibration frame 31. N and S poles are alternately arranged in the annular magnetic block area 312. An independent N or S pole magnetic pole 225 is arranged on the water inlet shaft 22, and is located in the same horizontal plane as the annular magnetic block area 312. The magnetic pole 225 is located below the water outlet 2211 and is located in the same longitudinal plane as the water outlet 2211.

[0031] The water inlet shaft 22 rotates, and when the water outlet 2211 enters the accommodating cavity 2341, the magnetic pole 225 just begins to enter the area of ​​the annular magnetic block area 312. As the water inlet shaft 22 rotates, the magnetic pole 225 alternately passes through the N and S poles on the annular magnetic block area 312, so that the vibration frame 31 moves back and forth along the radius line of the ultrafiltration membrane module 23. At the same time, the ultrafiltration membrane module 23 here is in a closed state, so the pressure difference inside and outside the membrane wire 232 is the same, so that the adsorption force of the attachment on the membrane wire 232 disappears, and the vibration frame 31 vibrates back and forth, so that the attachment on the membrane wire 232 falls off faster.

[0032] The water inlet shaft 22 is also provided with a sweeping plate 224, which is made of silicone and elastically pressed on the bottom surface of the filter barrel 1. The water inlet shaft 22 can rotate to scrape the bottom of the filter barrel 1, and the material drop chute 11 is located on the sweeping path of the sweeping plate 224. An induction switch is provided on the material drop chute 11. When the sweeping plate 224 passes through the material drop chute 11, the electric switch plate is automatically opened, so that all the scraped and accumulated sediments fall downward from the material drop chute 11.

[0033] The extrusion device 4 includes an extrusion box 41, a hydraulic push plate 42 and a filter device 43. An extrusion chamber 411 and a cleaning chamber 414 are arranged in the extrusion box 41. An extrusion water pipe 412 is arranged at the front end of the extrusion chamber 411. The extrusion water pipe 412 is connected to the filter barrel 1, and a one-way valve is arranged in the extrusion water pipe 412. Only the extrusion water pipe 412 can inject water into the filter barrel 1. A total water inlet 416 is arranged at the front end of the cleaning chamber 414, and the rear end is connected to the rotating joint at the lower end of the water inlet shaft 22 through a hose. Therefore, water can be supplied when the water inlet shaft 22 rotates. A sliding valve is also arranged at the bottom of the extrusion chamber 411. A sliding bottom plate 413 is provided, and a filter sliding groove 415 is horizontally opened at the front end of the extrusion chamber 411 and the cleaning chamber 414. The filter device 43 is arranged at the front end of the sliding bottom plate 413. The sliding bottom plate 413 is controlled by an electric push rod and can slide left and right, and slide back and forth in the extrusion chamber 411 and the cleaning chamber 414. The filter device 43 slides in the filter sliding groove 415 following the sliding bottom plate 413. At the same time, the bottom of the extrusion chamber 411 is opened, and the bottom of the cleaning chamber 414 is provided with a sealing plate. Therefore, when the sliding bottom plate 413 enters the cleaning chamber 414, the bottom of the extrusion chamber 411 is in an open state.

[0034] In the initial state, the sliding bottom plate 413 is located below the extrusion chamber 411, serving as the bottom surface of the extrusion chamber 411, and the filter device 43 is located in front of the extrusion chamber 411. At this time, the electric switch plate on the drop chute 11 is opened, and the sediment falls into the extrusion chamber 411. After the electric switch plate is closed, the hydraulic push plate 42 starts to work and squeezes forward to squeeze the sediment forward, and the squeezed water flows back to the filter barrel 1 through the extrusion water pipe 412 after passing through the filter device 43. After the hydraulic push plate 42 moves forward for a distance, it starts Retract backward. During the retraction process, the sliding bottom plate 413 is controlled to move into the cleaning chamber 414, so that the bottom of the extrusion chamber 411 is opened, and the extruded sediment automatically falls downward into the collecting bucket 5. At this time, the filter device 43 is located at the front end of the cleaning chamber 414, and the water flow direction of the cleaning chamber 414 moves from the front end to the rear end of the cleaning chamber 414. Therefore, after the filter device 43 moves to the front end of the cleaning chamber 414, the incoming water reversely flushes the filter device 43, and the flushed water is flushed into the filter barrel 1 for filtration.

[0035] The filter device 43 has a filter only in the middle and is surrounded by sealing plates. Therefore, when the sliding bottom plate 413 is located below the extrusion chamber 411, the water flow in the cleaning chamber 414 cannot enter the extrusion chamber 411; when the sliding bottom plate 413 is located in the cleaning chamber 414, the water flow in the cleaning chamber 414 cannot enter the extrusion chamber 411. At the same time, the left and right sliding of the sliding bottom plate 413 is quickly completed by an electric push rod.

[0036] The distance that the hydraulic push plate 42 moves forward can be adjusted through a program, so that the degree of dryness of the extruded material in the extrusion chamber 411 can be controlled.

[0037] Its working principle or usage is as follows:

[0038] The bottom end of the water inlet shaft 22 is connected to the main water inlet pipe through the cleaning chamber 414, so it is always in a water-passing state. At the same time, the water inlet shaft 22 is always in rotation driven by the motor. When the water inlet shaft 22 rotates, the water outlet 2211 and the annular magnetic block 223 thereon rotate together. During the rotation, the water outlet 2211 is aligned with the accommodating chamber 2341 of the ultrafiltration membrane module 23. At this time, the annular magnetic block 223 is already located at the front end of the magnetic switch plate 2311 on the ultrafiltration membrane module 23 here, thereby blocking the water outlet 231. The ultrafiltration membrane module 23 at this position stops working and switches to flushing work. The water flows downward from the flushing port 233. At the same time, when the water outlet 2211 enters the accommodating cavity 2341, the magnetic pole 225 just begins to enter the area of ​​the annular magnetic block area 312. As the water inlet shaft 22 rotates, the magnetic pole 225 alternately passes through the N and S poles on the annular magnetic block area 312, so that the vibration frame 31 moves back and forth along the radius line of the ultrafiltration membrane module 23. At the same time, the ultrafiltration membrane module 23 here is in a closed state, so the pressure difference inside and outside the membrane wire 232 is the same, so that the adsorption force of the attachments on the membrane wire 232 disappears, and the vibration frame 31 vibrates back and forth, so that the attachments on the membrane wire 232 fall off faster.

[0039] At the same time, the water inlet shaft 22 rotates, and the sweeping plate 224 thereon scrapes the bottom of the filter barrel 1, and the material drop trough 11 is located on the sweeping path of the sweeping plate 224. When the sweeping plate 224 passes through the material drop trough 11, the electric switch plate automatically opens, so that all the scraped and accumulated sediment falls downward from the material drop trough 11. After the sweeping plate 224 leaves the material drop trough 11, the electric switch plate automatically closes, and the bottom of the filter barrel 1 is closed again.

[0040] After the electric switch plate on the drop chute 11 is opened, the sediment falls into the extrusion chamber 411. After the electric switch plate is closed, the hydraulic push plate 42 starts to work and squeezes forward to squeeze the sediment forward. The water re-enters the filter barrel 1 through the filter device 43, and the sediment remains in the extrusion chamber 411. After the hydraulic push plate 42 moves forward for a distance, it begins to retract backward. During the retraction process, the sliding bottom plate 413 is controlled to move into the cleaning chamber 414, so that the bottom of the extrusion chamber 411 is opened, and the extruded sediment automatically falls downward into the collecting bucket 5. At this time, the filter device 43 is located at the front end of the cleaning chamber 414, and the water flow direction of the cleaning chamber 414 is from the front end to the rear end of the cleaning chamber 414. Therefore, after the filter device 43 moves to the front end of the cleaning chamber 414, the incoming water reversely flushes the filter device 43, and the flushed water is flushed into the filter barrel 1 for filtration, so that the filter device 43 is in a clean state again.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
