Description

Technical Field

[0001] The present invention relates to the technical field of drinking water treatment, in particular to a drinking water treatment device and its treatment process. Background Art

[0002] In recent years, the pollution of drinking water sources in China has become increasingly serious. If directly drunk without effective treatment, it will bring serious harm to people's health.

[0003] For example, in "CN119591193A", a drinking water treatment device includes a box body. An inlet pipe is communicatively connected to the left side of the box body, and an outlet pipe is communicatively connected to the right side of the box body. A partition is fixedly connected to the inner wall of the box body, and the number of partitions is two. An adsorption mechanism is arranged on the partition. The adsorption mechanism includes a driving motor, a rotating plate, a telescopic rod, an activated carbon frame, a baffle, a support plate, a pull rod, and a control button. The driving motor is fixedly installed on the rear partition. By setting the driving motor, the rotating plate, and the telescopic rod, the two activated carbon frames can be driven to switch, thereby effectively improving the adsorption effect of the activated carbon in the activated carbon frame. By setting the support plate, the pull rod, and the control button, automatic switching can be performed when the activated carbon in the activated carbon frame in the water body is saturated with adsorption, without manual switching, which is more time-saving and labor-saving and improves the water treatment effect.

[0004] In a drinking water treatment system, as the core filtering medium, the filter plate needs to be regularly disassembled for cleaning or replacement. Usually, the filter plate is vertically pulled out upward. However, during this process, when the filter plate is pulled out upward, the slightly attached dirt on the surface will partially break away from the filter plate due to shaking or water flow surging and fall back into the water again. Since some dirt is mostly in a loose state, it is easy to be redispersed in the filtering device along with the water flow, which not only increases the burden of subsequent filtration but also may cause short-term fluctuations or pollution of the local water quality. Summary of the Invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that when the filter plate is disassembled, the dirt slightly attached to the filter plate is likely to fall back into the water again, increasing the filtration burden.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a drinking water treatment device, which includes a treatment tank and a water inlet pipe, the water inlet pipe is connected and arranged at the water inlet end of the treatment tank, a filter plate is provided in the treatment tank, a fixed frame is provided in the treatment tank, a plurality of filter plates are provided and are slidably arranged on the fixed frame from top to bottom, a square frame is provided above one end of the filter plate close to the water inlet pipe, a scraper is provided on the side of the square frame close to the filter plate and is in contact with the filter plate, a filter pocket is connected above the square frame, the square frame and the filter plate are linked by a reverse driving mechanism, a conveyor belt is provided above the fixed frame through a bracket, the filter plate is driven to move by the conveyor belt, and a partition bar is provided on the side of the filter plate away from the water inlet pipe.

[0009] Furthermore, an assembly groove is provided on the partition bar, and a first magnetic strip is provided in the assembly groove through a first spring. An inner groove adapted to the first magnetic strip is provided on the partition bar on the other side of the filter plate, and a second magnetic strip adsorbed to the first magnetic strip is provided in the inner groove. The partition bar is used to separate adjacent filter plates for a distance, and the adaptation of the inner groove to the first magnetic strip can ensure that adjacent filter plates are always level and can remain stable even during movement. The mutual adsorption of the first magnetic strip and the second magnetic strip makes it difficult for adjacent partition bars to separate and cause the filter plate to tip over.

[0010] Furthermore, a battery is provided in the partition bar, a first conductive sheet is provided on one side of the second magnetic strip, a seesaw is provided inside the partition bar which is rotated by a rotating shaft, a second conductive sheet is provided below one end of the seesaw, the second conductive sheet is located directly above the first conductive sheet, an insertion strip is slidably penetrated through the partition bar above the other end of the seesaw, the lower end of the insertion strip is hingedly connected to the top of the seesaw through a hinge block, the second conductive sheet is electrically connected to the battery, and the seesaw is assembled and connected to the interior of the partition bar below one end through a fourth spring, and by pressing downward on the insertion strip extending to the outside of the partition bar, the lower end of the insertion strip pushes one end of the seesaw downward, and one end of the seesaw provided with the second conductive sheet rotates upward around the rotating shaft and separates from the first conductive sheet, thereby disconnecting the second magnetic strip. After power failure, the first magnetic strip is reset to the assembly groove under the pulling force of the first spring, and is separated from the adjacent inner groove, which facilitates the up and down movement of adjacent filter plates and facilitates disassembly.

[0011] Further, plate side grooves are symmetrically provided on the side walls of the filter plate, frame side grooves are provided inside the fixing frame, first magnetic blocks are slidably arranged in the frame side grooves through second springs, one side of each first magnetic block is slidably arranged in the plate side grooves, second magnetic blocks that repel the first magnetic blocks are provided at the inner ends of the frame side grooves, bottom grooves are symmetrically provided on both sides below the fixing frame, sliders that are slidably arranged in the bottom grooves are provided below the filter plate, transverse grooves are communicated between the plurality of frame side grooves, clamping blocks adapted to the transverse grooves are provided on the side edges of the filter plate. After the filter plate is installed, the second magnetic blocks can be energized to repel the first magnetic blocks, pushing the first magnetic blocks to move into the plate side grooves until they are clamped into the plate side grooves, so as to position the filter plate and prevent it from sliding randomly. Through the cooperation of the sliders and the bottom grooves, the position of the filter plate in the fixing frame is limited. Through the cooperation of the clamping blocks and the transverse grooves, when the filter plate is completely installed in the fixing frame, the clamping blocks are just located in the transverse grooves, so as to limit the up and down position of the filter plate. When moving back and forth, the filter plate will not move up and down.

[0012] Further, an adjustment groove is formed in the fixing frame, an adjustment shaft is slidably inserted up and down in the adjustment groove, the adjustment groove is communicated with the frame side groove, a first conductive strip is provided on the second magnetic block, an adjustment plate is rotatably arranged in the adjustment groove, one end of the adjustment plate extends into the adjustment groove, and a second conductive strip electrically connected to the first conductive strip is provided at the other end. The adjustment plate is assembled and connected to the adjustment groove through a fifth spring. In the initial state, under the action of the fifth spring, the end of the adjustment plate provided with the second conductive strip is in close contact with the first conductive strip. When adjustment is required, the adjustment shaft is pressed down, the lower end of the adjustment shaft squeezes the lower end of the adjustment plate to rotate, and the end of the adjustment plate provided with the second conductive strip tilts up and separates from the first conductive strip, realizing power-off. At this time, under the action of the second spring, the first magnetic block resets into the frame side groove and separates from the filter plate, and the filter plate loses its limit, facilitating forward and backward movement and up and down movement. The second conductive strip is electrically connected to an external power source.

[0013] Further, the conveyor belt is located directly above a plurality of filter plates near the central position, the conveyor belt does not contact the two filter plates at both ends, tooth grooves are provided on the outer wall of the conveyor belt, and tooth plates meshing with the tooth grooves are provided above the filter plates. By driving the conveyor belt to rotate, the filter plates below can be driven to move, facilitating the forward movement of the remaining filter plates after one filter plate is removed.

[0014] Further, the upper end of the filter plate extends above the fixing frame. The reverse driving mechanism includes a long gear and a strip plate. The long gear is rotatably arranged above the inner wall of the fixing frame near one end of the water inlet pipe. The side of the square frame away from the filter plate is meshed with the long gear through the strip plate. The side of the square frame is slidably arranged up and down with the inner wall of the fixing frame. The long gear is meshed with the two side edges of the filter plate. The outer end of the strip plate is assembled and connected with the fixing frame through a cylinder. When disassembling the filter plate, by driving the cylinder to contract and move downward, the square frame is driven to move downward, and then the long gear is driven to rotate, realizing the upward movement of the filter plate in the reverse direction. During this process, the scraper on one side of the square frame can scrape off the dirt on the surface of the filter plate. Most of the dirt directly enters the square frame and is collected in the filter pocket, which can prevent the scraped dirt from staying in the water.

[0015] Further, two sealing plates are rotatably arranged on both sides inside the square frame. The inner sides of the sealing plates are assembled and connected with the inner side of the square frame through third springs. Sealing members are arranged at the inner wall and the central position of the square frame. The two sealing plates are hermetically connected with the sealing members. The open end of the filter pocket is hermetically magnetically attracted to the end face of the square frame. When the square frame moves downward, the scraper scrapes off the dirt attached to the surface of the filter plate. When the filter plate moves upward and the square frame and the filter pocket move downward, the sewage is quickly collected into the square frame. When the water flow enters quickly, the water flow pushes open the two sealing plates and rotates them to open, and the water flow smoothly enters the filter pocket. When it moves to the bottom and stops moving, without external force impact, the third spring pulls the sealing plates to reset, avoiding the dirt entering the filter pocket from overflowing. The square frame is reset to the upper end under the action of the cylinder, and the staff can pull out the filter pocket from the end face of the square frame for cleaning and magnetically install it in the square frame during use.

[0016] Further, a rear frame is arranged inside the fixing frame away from one end of the water inlet pipe. An inclined plate is arranged on one side of the rear frame through an auxiliary spring. One side of the inclined plate abuts against the partition strip at the upper end of the filter plate. The auxiliary spring is arranged to push the last filter plate forward.

[0017] On the other hand, the present invention provides a drinking water treatment process, including,

[0018] Step S1: Take out the drinking water source from surface water and groundwater, and perform pretreatment on the water, that is, preliminary filtration, sand sedimentation, and pH value adjustment;

[0019] Step S2: The pretreated sewage enters the mixing tank, flocculant is added and stirred and mixed. After sedimentation treatment, the upper clear water is taken and introduced into the treatment tank through the water inlet pipe for further treatment, and the sediment after sedimentation is discharged;

[0020] Step S3, sewage is introduced from the water inlet pipe, filtered layer by layer through the multi-layer filter plates, and then discharged from the output end of the treatment tank. After a period of use, the surface of the filter plate accumulates a lot of dirt, and the filter plate near the end of the water inlet pipe is removed by pressing the insert and the adjustment shaft respectively to separate the adjacent filter plates and the filter plates from the fixing frame, and then the cylinder is driven to contract, driving the strip plate to move downward, and the square frame moves downward while the filter plate moves up to achieve disassembly;

[0021] Step S4: After a filter plate close to the water inlet pipe is removed, the conveyor belt is driven to rotate, driving the multiple filter plates below to move toward the front end, until the filter plate originally located at the second position is pushed to the first position, replacing the position of the removed filter plate. During the rotation of the conveyor belt, the setting of the auxiliary spring can push the filter plate located at the last position forward until it is located under the conveyor belt and drives it to move forward;

[0022] Step S5: a filter plate space is left at one end of the fixing frame away from the water inlet pipe, and a staff member takes a clean filter plate and inserts it into the space from top to bottom;

[0023] Step S6, disinfecting the water body and performing secondary pH adjustment, anti-corrosion and descaling treatment, and regulation of nutrients and minerals;

[0024] Step S7: After all the treatment processes, qualified drinking water is stored in a dedicated water storage tank or water tower for drinking water supply.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention utilizes a reverse driving mechanism to reversely link the filter plate and the square frame. When the filter plate is taken out upward, the square frame moves downward, and the loosely attached dirt on the surface of the filter plate is removed and collected into the filter pocket. With the provided sealing plate structure, the dirt can be temporarily stored in the filter pocket in the absence of water flow impact, thereby preventing some obvious dirt from being re-scattered into the water and increasing the filtration burden.

[0027] 2. The present invention sets up multiple filter plates. When the filter plates are disassembled, only the frontmost filter plate is disassembled, and the other filter plates move forward after the front filter plate is moved out to replace the front filter plate. This can always keep the frontmost filter plate with the most dirt. Therefore, only the frontmost filter plate needs to be replaced each time, and there is no need to remove all the filter plates at once. The operator only needs to replace or clean a single filter plate, thereby reducing the downtime of the overall system.

[0028] 3. The partition bars provided in the present invention are used to separate adjacent filter plates by a certain distance. The adaptation of the inner groove and the first magnetic strip can ensure that adjacent filter plates are always horizontal and remain stable even during movement. The mutual adsorption of the first magnetic strip and the second magnetic strip makes it difficult for adjacent partition bars to separate, preventing the filter plates from tipping over.

[0029] 4. By pressing down on the insert bar that extends outside the partition bar, the lower end of the insert bar pushes one end of the rocker plate downward. The end of the rocker plate with the second conductive sheet rotates upward around the rotating shaft and separates from the first conductive sheet, realizing the power-off of the second magnetic strip. After power-off, the first magnetic strip is reset to the assembly groove under the pulling force of the first spring and disengages from the adjacent inner groove. At this time, it is convenient for adjacent filter plates to move up and down, facilitating disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

The mutual adsorption of the first magnetic strip 713 and the second magnetic strip 715 makes it difficult for adjacent partition bars 6 to separate and cause the filter plate 3 to tip over.

[0048] like Figures 1 - 10 As shown, a battery 721 is provided in the spacer bar 6, a first conductive sheet 722 is provided on one side of the second magnetic strip 715, a seesaw 724 is provided inside the spacer bar 6 through a rotating shaft 723, a second conductive sheet 725 is provided below one end of the seesaw 724, the second conductive sheet 725 is located directly above the first conductive sheet 722, an insertion strip 726 is slidably penetrated on the spacer bar 6 above the other end of the seesaw 724, the lower end of the insertion strip 726 is hinged to the top of the seesaw 724 through a hinge block, the second conductive sheet 725 is electrically connected to the battery 721, and a fourth elastic sheet 726 is provided below one end of the seesaw 724 The spring 727 is assembled and connected to the inner part of the partition bar 6.

The rocker 724 is provided with one end of the second conductive sheet 725 which rotates upward around the rotating shaft 723 and separates from the first conductive sheet 722, thereby disconnecting the second magnetic strip 715. After power failure, the first magnetic strip 713 is reset to the assembly groove 711 under the pulling force of the first spring 712, and is separated from the adjacent inner groove 714. At this time, it is convenient for the adjacent filter plate 3 to move up and down, and it is easy to disassemble.

The cooperation between the slider 817 and the bottom groove 816 is used to limit the position of the filter plate 3 in the fixing frame 411. Through the cooperation between the block 822 and the transverse groove 821, when the filter plate 3 is completely installed in the fixing frame 411, the block 822 is just in the transverse groove 821, which is used to limit the upper and lower positions of the filter plate 3. When moving forward and backward, the filter plate 3 will not move up and down.

[0050] like Figures 1 - 10 As shown, an adjustment slot 831 is provided in the fixing frame 411, an adjustment shaft 832 is inserted and slidably inserted in the adjustment slot 831, the adjustment slot 831 is communicated with the frame side slot 812, a first conductive strip 833 is provided on the second magnetic block 815, an adjustment plate 834 is rotatably provided in the adjustment slot 831, one end of the adjustment plate 834 extends into the adjustment slot 831, and the other end is provided with a second conductive strip 835 electrically connected to the first conductive strip 833, the adjustment plate 834 is assembled and connected to the adjustment slot 831 through a fifth spring 836, and in the initial state, the adjustment plate 834 is under the action of the fifth spring 836. At the bottom, one end of the second conductive strip 835 is tightly fitted with the first conductive strip 833. When adjustment is needed, the adjusting shaft 832 is pressed down, and the lower end of the adjusting shaft 832 squeezes the lower end of the adjusting plate 834 to rotate, and one end of the second conductive strip 835 provided on the adjusting plate 834 is lifted up and separated from the first conductive strip 833 to achieve power off. At this time, under the action of the second spring 813, the first magnetic block 814 is reset to the side groove 812 of the frame and separated from the filter plate 3. The filter plate 3 loses its limit, which is convenient for moving forward and backward and up and down, and the second conductive strip 835 is electrically connected to the external power supply.

[0051] like Figures 1 - 10As shown in the figure, the conveyor belt 512 is located directly above a plurality of filter plates 3 near the central position. The conveyor belt 512 does not contact the two filter plates 3 at both ends. The outer wall of the conveyor belt 512 is provided with tooth grooves 911, and above the filter plate 3 is provided with a toothed plate 912 meshed with the tooth grooves 911. By driving the conveyor belt 512 to rotate, the filter plates 3 below can be driven to move, which is convenient for pushing the remaining filter plates 3 forward after removing one filter plate 3.

[0052] As Figures 1 - 10 shown, the upper end of the filter plate 3 extends above the fixed frame 411. The reverse drive mechanism includes a long gear 101 and a strip plate 102. The long gear 101 is rotatably arranged above the inner wall of the fixed frame 411 near one end of the water inlet pipe 2. One side of the square frame 412 away from the filter plate 3 is meshed with the long gear 101 through the strip plate 102. The side of the square frame 412 is slidably arranged up and down with the inner wall of the fixed frame 411. The long gear 101 is meshed with the two side edges of the filter plate 3. The outer end of the strip plate 102 is assembled and connected to the fixed frame 411 through a cylinder 103. When disassembling the filter plate 3, by driving the cylinder 103 to contract and move downwards, the square frame 412 is driven to move downwards, and then the long gear 101 is driven to rotate, realizing the reverse upward movement of the filter plate 3. During this process, a scraper 413 on one side of the square frame 412 can scrape the dirt on the surface of the filter plate 3. Most of the dirt directly enters the square frame 412 and is collected in the filter pocket 414, which can prevent the scraped dirt from staying in the water.

[0053] As Figures 1 - 10 shown, on both sides inside the square frame 412 are rotatably arranged sealing plates 111. The inner sides of the sealing plates 111 are assembled and connected to the inner side of the square frame 412 through third springs 112. Sealing members 113 are arranged on the inner wall and the central position of the square frame 412. The two sealing plates 111 are sealingly connected to the sealing members 113. The open end of the filter pocket 414 is sealingly magnetically attracted to the end face of the square frame 412. When the square frame 412 moves downwards, the scraper 413 scrapes the dirt attached to the surface of the filter plate 3. When the filter plate 3 moves upwards and the square frame 412 and the filter pocket 414 move downwards, the sewage is quickly collected into the square frame 412. When the water flow enters quickly, the water flow pushes open the two sealing plates 111 to rotate and open, and the water flow smoothly enters the filter pocket 414. When it moves to the bottom and stops moving, without external force impact, the third spring 112 pulls the sealing plate 111 to reset, avoiding the dirt in the filter pocket 414 from overflowing. The square frame 412 is reset to the upper end under the action of the cylinder 103, and the staff pulls out the filter pocket 414 from the end face of the square frame 412 for cleaning, and it can be magnetically installed in the square frame 412 during use.

[0054] As Figures 1 - 10As shown, a rear frame 121 is provided on the inner side of one end of the fixing frame 411 away from the water inlet pipe 2. One side of the rear frame 121 is provided with an inclined plate 123 through an auxiliary spring 122. One side of the inclined plate 123 abuts against the partition bar 6 at the upper end of the filter plate 3. The auxiliary spring 122 is provided to push the last filter plate 3 forward.

[0055] Working principle:

[0056] Step S1, taking drinking water from surface water and groundwater, and pre-treating the water, i.e., preliminary filtration, sand settling and pH adjustment;

[0057] Step S2, the pretreated sewage enters the mixing tank, flocculants are added and stirred, and after sedimentation treatment, the upper layer of clear water is taken and introduced into the treatment tank 1 through the water inlet pipe 2 for further treatment, and the precipitated sludge is discharged;

[0058] Step S3, sewage is introduced from the water inlet pipe 2, filtered layer by layer through the multi-layer filter plates 3, and then discharged from the output end of the treatment tank 1. After a period of use, the surface of the filter plates 3 is heavily covered with dirt. The filter plates 3 are removed by removing the end close to the water inlet pipe 2.
