Description

Technical Field

[0001] The utility model relates to the technical field of purified water treatment, in particular to a purified water processing and filtering device. Background Art

[0002] The requirements for water treatment are usually high, especially for the treatment of purified water. The raw water is initially filtered using a filter device to filter out impurities such as suspended matter and particulate matter in the raw water. During the use of the current filter device, impurities such as suspended matter and particulate matter will settle on the surface of the filter material. When the impurities accumulate more and more, they will clog the filter material and affect the efficiency of water filtration. Some impurities have the risk of penetrating the filter material under the action of water pressure, thereby affecting the effect of water filtration. In response to the above problems, one way is to use a backwashing mechanism to clear impurities from the filter material, but the water filtration operation needs to be stopped during the backwashing process. Another way is to replace the filter material or switch to a standby filter device. Although the water filtration does not need to be stopped, the cost of the filter material and the filter device increases, and other equipment is needed to clear impurities from the filter material.

To this end, the utility model provides a purified water processing and filtering device, which can timely remove impurities from the filter material, filter water continuously, and ensure the effect of water filtering.

[0006] The tank body and multiple support frames cooperate to divide the cleaning chamber from left to right into multiple filter chambers, multiple water collection chambers and a clean water chamber, and the filter chambers and water collection chambers are spaced apart. The raw water to be filtered outside the tank body is injected into the leftmost filter chamber through the water inlet pipe. Under the action of the raw water, the raw water first presses the filter cloth against the support frame, and then passes through the filter cloth and the mesh on the mesh plate of the leftmost support frame. At this time, the raw water is filtered once by the filter cloth to obtain the first-level water entering the water collection chamber. Due to the obstruction of the baffle, the first-level water will enter the next filter chamber through the bend pipe.

[0007] The more water the filter cloth filters, the more impurities are precipitated or accumulated on the filter cloth. At this time, the driving device drives the filter cloth to move along the loop, and the area with more impurities on the filter cloth moves to the cleaning chamber. The flushing mechanism flushes the front and back of the filter cloth to clean the impurities on the filter cloth, and then the filter cloth in this area enters the filter chamber and the water collection chamber again, and the filter cloth in this area can filter water again. It is possible to filter water and clean impurities in different areas of the filter cloth at the same time.

[0036] Reference Figures 1 to 3 The utility model discloses a purified water processing and filtering device, comprising a tank body 100, a filter cloth 800, a flushing mechanism, a driving device, a plurality of support frames 400, and a plurality of curved pipes 900 arranged at the bottom of the front wall of the tank body 100 or the bottom of the rear wall of the tank body 100;

[0037] A slot cavity is formed on the upper surface of the tank body 100, and a partition plate 110 is provided in the slot cavity. The partition plate 110 divides the slot cavity into a cleaning chamber 200 and a filter chamber 300 distributed on the left and right. A left guide roller 120 and a right guide roller 130 are provided at the upper parts of the left and right ends of the slot cavity, respectively. A support roller 111 is provided at the top of the partition plate 110. A bottom guide roller 210 is provided at the lower part of the cleaning chamber 200. A slag discharge pipe 220 is provided on the bottom wall of the cleaning chamber 200, and the slag discharge pipe 220 extends to the outside of the tank body 100.

[0038] Reference Figure 2 and Figure 3 A plurality of support frames 400 are sequentially arranged on the bottom wall of the filter chamber 300 along the left and right directions. The support frame 400 includes a baffle plate 410 and a mesh plate 420 connected to each other. The baffle plate 410 and the mesh plate 420 are V-shaped. The support frame 400, the front wall of the tank body 100 and the rear wall of the tank body 100 form a filter chamber 500. The side wall of the filter chamber 500 on the far left is provided with a water inlet pipe 330, which extends to the tank body 100. Outside, the front wall of the tank body 100, the rear wall of the tank body 100, the bottom wall of the tank body 100 and two adjacent support frames 400 form a water collecting chamber 600, the front wall of the tank body 100, the rear wall of the tank body 100, the bottom wall of the tank body 100, the right wall of the tank body 100 and the rightmost support frame 400 form a clean water chamber 700, the bottom wall of the clean water chamber 700 is provided with a clean water pipe 340, and the clean water pipe 340 extends to the outside of the tank body 100;

[0039] Reference Figure 1 and Figure 3 , the filter cloth 800 is sequentially wound around the left guide roller 120, the right guide roller 130, the bottom guide roller 210 and the support roller 111 and connected end to end to form a loop, and a part of the filter cloth 800 is against the inner wall of all the support frames 400 to cover the meshes 421 of all the mesh plates 420;

[0040] The two ends of the elbow 900 are connected to the bottom of the adjacent filter chamber 500 and the bottom of the water collection chamber 600, respectively. The two ends of the rightmost elbow 900 are connected to the bottom of the rightmost filter chamber 500 and the bottom of the water purification chamber 700, respectively.

[0041] The flushing mechanism is arranged in the cleaning chamber 200, and is used to flush the front and back sides of the filter cloth 800;

[0042] The driving device is used to drive the filter cloth 800 to move along the loop.

[0043] The tank body 100 and the plurality of support frames 400 cooperate to divide the cleaning chamber 200 from left to right into a plurality of filter chambers 500, a plurality of water collecting chambers 600 and a water purification chamber 700, wherein the filter chambers 500 and the water collecting chambers 600 are spaced apart from left to right.

[0044] The raw water to be filtered outside the tank body 100 is injected into the leftmost filter chamber 500 through the water inlet pipe 330. Under the action of the raw water, the raw water first presses the filter cloth 800 against the support frame 400, and then passes through the filter cloth 800 and the mesh 421 on the mesh plate 420 of the leftmost support frame 400. At this time, the raw water is filtered once by the filter cloth 800 to obtain the first-level water entering the water collection chamber 600. Due to the obstruction of the baffle 410, the first-level water will enter the next filter chamber 500 through the bend pipe 900, and so on. The raw water enters different filter chambers 500 and different water collection chambers 600 in turn to obtain multi-level water, that is, the raw water is filtered multiple times to obtain clean water. The clean water enters the clean water chamber 700 and is discharged to the outside of the tank body 100 through the clean water pipe 340.

[0045] The raw water is filtered by the filter cloth 800 multiple times, and each time the water passes through the filter cloth 800 from the front surface to the back surface. The front surface is the outer side of the meandering filter cloth 800, and the back surface is the inner side of the meandering filter cloth 800, thereby avoiding the situation where water backwashes the filter cloth 800 and ensuring the water purification effect.

[0046] The more water the filter cloth 800 filters, the more impurities are precipitated or accumulated on the filter cloth 800. At this time, the driving device drives the filter cloth 800 to move along the loop, and the area with more impurities on the filter cloth 800 moves to the cleaning chamber 200. The flushing mechanism flushes the front and back sides of the filter cloth 800 to clean up the impurities on the filter cloth 800, and then the filter cloth 800 in this area enters the filter chamber 500 and the water collection chamber 600 again, and the filter cloth 800 in this area can filter water again.

[0047] Different areas of the filter cloth 800 can be filtered and impurities can be removed simultaneously. The filter cloth 800 moves in a circular motion without stopping to filter water, so that the filter cloth 800 can be cleaned and put back into use again, achieving uninterrupted water filtration, and the water filtration effect is guaranteed, thus avoiding the cost of the filter cloth 800 material and the cost of cleaning.

[0048] The specific working process of the filter cloth 800 is as follows: as the time of filtering raw water increases, more and more impurities accumulate on the filter cloth 800, and the driving device can be started. The driving device drives the filter cloth 800 to move along the loop. When the area with impurities on the filter cloth 800 enters the cleaning chamber 200, the flushing mechanism flushes the front and back sides of the filter cloth 800, and the impurities flushed off the filter cloth 800 are discharged to the outside of the tank body 100 through the slag discharge pipe 220. After the area with impurities on the filter cloth 800 is flushed clean, as the driving device continues to drive the filter cloth 800 to move along the loop, the area on the filter cloth 800 that is flushed clean is re-covered on the mesh 421 of the support frame 400, and the area on the filter cloth 800 that is flushed clean plays the role of filtering raw water again. When flushing the area with impurities on the filter cloth 800, the other areas of the filter cloth 800 are still covered on the mesh 421 of the support frame 400, that is, the process of the filter cloth 800 filtering raw water will not be interrupted. Ultimately, the filter device can complete the cleaning of the filter cloth 800 without interrupting the raw water filtration work, which is convenient and quick.

[0049] The flushing mechanism flushes the front and back sides of the filter cloth 800 to ensure the effect of cleaning the filter cloth 800. The cleaner the filter cloth 800 is, the more conducive it is to improving the efficiency and effect of filtering raw water by the filter device. The filter cloth 800 is arranged in an inverted W shape in the filter chamber 300, that is, the filter cloth 800 is folded and distributed. In the limited space of the filter chamber 300, the effective filtering area of ​​the filter cloth 800 in the filter chamber 300 can be larger, which is conducive to improving the filtering efficiency of the filter device.

[0050] Reference Figure 3 In some embodiments, the upper ends of adjacent mesh plates 420 are connected to the upper ends of the baffle plates 410, and an upper guide roller 370 is provided between the upper ends of the adjacent mesh plates 420 and the upper ends of the baffle plates 410, and a lower guide roller 380 is provided on the inner bottom of the support frame 400, and the filter cloth 800 is alternately wound around the lower guide roller 380 and the upper guide roller 370. The setting of the upper guide roller 370 and the lower guide roller 380 can reduce the friction resistance encountered by the filter cloth 800 when moving.

[0051] The filter cloth 800 is alternately wound around the lower guide roller 380 and the upper guide roller 370. The upper guide roller 370 and the lower guide roller 380 limit the filter cloth 800 to bend in a W shape, and cooperate with water to press the filter cloth 800 onto the support frame 400 to prevent the filter cloth 800 from detaching from the support frame 400, ensuring that the filter cloth 800 always covers all the mesh holes 421, thereby preventing sewage from directly passing through the mesh holes 421 without passing through the filter cloth 800.

[0052] It is conceivable that the lower end of the baffle 410 and the lower end of the mesh plate 420 are connected via a transition plate, the transition plate is detachably sealed and connected to the bottom wall of the filter chamber 300 via a fastener, and the front and rear ends of the baffle 410 / mesh plate 420 are respectively sealed and connected to the front and rear inner walls of the filter chamber 300. The lower guide roller 380 is disposed on the transition plate. It is further conceivable that sealing strips are disposed between the transition plate and the bottom wall of the filter chamber 300, between the front and rear ends of the baffle 410 and the front and rear inner walls of the filter chamber 300, and between the front and rear ends of the mesh plate 420 and the front and rear inner walls of the filter chamber 300.

[0053] See also Figure 2 The support frame 400 can be formed by bending a stainless steel plate, and the two ends of the steel plate are bent into a V shape, and the angle between the two ends of the steel plate can be 15° to 45°. Of course, the support frame 400 can also be formed by splicing two stainless steel plates.

[0054] In some of the embodiments, both ends of the left guide roller 120, the right guide roller 130, the support roller 111, the bottom guide roller 210, the upper guide roller 370 and the lower guide roller 380 are provided with annular limit baffles, which serve to block the filter cloth 800, so that the left guide roller 120, the right guide roller 130, the support roller 111, the bottom guide roller 210, the upper guide roller 370 and the lower guide roller 380 can all serve to limit the direction of the filter cloth 800.

[0055] It is conceivable that the axial directions of the left guide roller 120 , the right guide roller 130 , the support roller 111 , the bottom guide roller 210 , the upper guide roller 370 , and the lower guide roller 380 are all front-to-back directions.

[0056] Reference Figure 1 and Figure 3 In some of the embodiments, an overflow pipe 350 is provided on the side wall of the leftmost filter chamber 500. The overflow pipe 350 is lower than the upper end of the mesh plate 420. The overflow pipe 350 extends to the outside of the tank body 100. When the water level of the raw water in the leftmost filter chamber 500 reaches the height of the overflow pipe 350, the raw water will be discharged to the outside of the tank body 100 through the overflow pipe 350, so as to prevent the raw water from directly overflowing the upper end of the mesh plate 420, thereby preventing the raw water from directly hitting the next filter chamber 500 without being filtered by the filter cloth 800.

[0057] The tube body of the overflow pipe 350 is connected to the rear wall of the filter cavity 500 , and the two ends of the tube cavity of the overflow pipe 350 are connected to the leftmost filter cavity 500 and the space outside the tank body 100 respectively.

[0058] Reference Figure 3In some embodiments, a drain pipe 360 ​​is provided on the bottom wall of each water collecting chamber 600, and all the drain pipes 360 extend to the outside of the tank body 100, and the water in the corresponding water collecting chamber 600 can be drained out of the tank body 100 in advance through the corresponding drain pipe 360. The water collecting chambers 600 are numbered from left to back, and the water can be drained out of the tank body 100 in advance through the drain pipe 360 ​​corresponding to the water collecting chamber 600 according to the number of times the raw water is filtered.

[0059] Reference Figure 1 In some of the embodiments, a water supply joint is provided on the rear wall of the trough body 100 in an area corresponding to the bottom of the water collecting chamber 600, and a water discharge joint is provided on the rear wall of the trough body 100 in an area corresponding to the bottom of the filter chamber 500. The front and rear opposite water supply joints and water discharge joints are respectively connected to the two ends of the elbow 900 to transport the water in the water collecting chamber 600 to the filter chamber 500. The provision of the water supply joint and the water discharge joint can improve the efficiency of installing the elbow 900.

[0060] Reference Figure 3 In some embodiments, the flushing mechanism includes an upper nozzle 230 and a lower nozzle 240 both of which are arranged in the cleaning chamber 200. The upper nozzle 230 is provided with an upper nozzle facing the front side of the filter cloth 800, and the upper nozzle sprays clean water or other cleaning liquid toward the front side of the filter cloth 800, and the clean water or other cleaning liquid can clean away impurities on the front side of the filter cloth 800; the lower nozzle 240 is provided with a lower nozzle facing the back side of the filter cloth 800, and the lower nozzle sprays clean water or other cleaning liquid toward the back side of the filter cloth 800, and the clean water or other cleaning liquid can clean away impurities on the back side of the filter cloth 800, so that the filter cloth 800 can be reused and used to filter sewage again.

[0061] The flushing mechanism also includes a flushing main pipe and a flushing pump on the flushing main pipe. The upper spray pipe 230 and the lower spray pipe 240 are both connected to the flushing main pipe, and the flushing main pipe can be connected to an external water source.

[0062] In some of the embodiments, the direction of the upper nozzle and the direction of the lower nozzle are at an angle to the moving direction of the filter cloth 800, that is, the moving direction of the clean water or other cleaning liquid sprayed by the upper nozzle is at an angle to the moving direction of the filter cloth 800, which will be more conducive to flushing impurities on the filter cloth 800.

[0063] It can be imagined that the directions of the upper nozzle and the lower nozzle form an obtuse angle with the moving direction of the filter cloth 800 , which is conducive to washing impurities on the filter cloth 800 and discharging them outside the tank body 100 through the slag discharge pipe 220 .

[0064] The bottom guide roller 210 is disposed at the lower end of the right inner wall of the cleaning chamber 200 , the upper nozzle 230 is located to the upper right of the lower nozzle 240 , and the line connecting the bottom guide roller 210 and the left guide roller 120 crosses the line connecting the upper nozzle 230 and the lower nozzle 240 .

[0065] Reference Figure 3 In some embodiments, the driving device includes a rotary driving device, an active roller 310 and a driven roller 320. The rotary driving device is arranged outside the tank body 100, and the rotary driving device does not occupy the space of the tank cavity. The active roller 310 and the driven roller 320 are both arranged in the tank cavity and below the right guide roller 130. The active roller 310 and the driven roller 320 clamp the filter cloth 800. The output end of the rotary driving device is transmission-connected with the active roller 310. The rotary driving device drives the active roller 310 to rotate, thereby driving the filter cloth 800 to move.

[0066] In some of the embodiments, the rotation driving device is a motor, which is disposed on the upper surface of the tank body, and the output end of the motor is connected to the active roller 310 by chain drive or belt drive.

[0067] It is understandable that the output end of the motor is provided with a driving sprocket, the driving roller 310 is provided with a driven sprocket, and the driving sprocket and the driven sprocket are connected by a chain. Alternatively, the output end of the motor is provided with a driving pulley, the driving roller 310 is provided with a driven pulley, and the driving pulley and the driven pulley are connected by a belt.

[0068] During the filtering process of the filtering device, some particles and suspended matter accumulate on the inner bottom of the support frame 400 and above the filter cloth 800. If they are not removed in time, the efficiency of the filtering device in filtering raw water will be affected.

[0069] In some of the embodiments, the filtration device also includes a suspended matter sedimentation layer suction mechanism, which includes a suction main pipe, a suction pump arranged on the suction main pipe, and a plurality of suction branch pipes connected to the suction main pipe, the suction branch pipes extending to the inner bottom of the support frame 400 and being located above the filter cloth 800, and the suction pump pumps the particles and suspended matter to the outside of the tank body 100 through the suction branch pipes and the suction main pipe.

[0070] It is conceivable that the tank body 100 is provided with an upper cover covering the slot opening of the tank cavity, and the upper cover can prevent other objects from falling into the tank cavity. The upper cover or the front wall of the tank body 100 or the rear wall of the tank body 100 is provided with windows in the area corresponding to the cleaning chamber 200 and the filter chamber 300, and the conditions in the cleaning chamber 200 and the filter chamber 300 can be directly seen through the windows.

[0071] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
