Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to softening water treatment equipment. Background Art

[0002] Traditional water treatment methods have gradually exposed many limitations when faced with complex and changeable pollutant components. For example, some physical filtration methods such as sand filtration and screen filtration can only remove larger suspended particles and impurities in the water, but are powerless against soluble harmful substances such as heavy metal ions (mercury, cadmium, lead, nickel, cobalt, etc.), organic pollutants (pesticides, dyes, phenolic substances, etc.) and ammonia nitrogen compounds. Although chemical precipitation can treat some heavy metal ions to a certain extent, it often requires the addition of a large amount of chemical agents, which is not only costly, but also easy to introduce new impurities. The subsequent treatment process is cumbersome and may also produce a large amount of difficult-to-treat sludge, causing secondary pollution.

[0003] A Chinese patent document with authorization announcement number CN211733904U discloses a resin adsorption tank for water treatment, which includes a cylinder, one end of which is detachably connected to an upper head and the other end of which is detachably connected to a lower head, the upper head is provided with a water outlet, and the lower head is provided with a water inlet; a flower plate assembly located in the cylinder is provided at the connection between the upper head and the cylinder, and at the connection between the lower head and the cylinder; a resin filling area for filling adsorption resin is formed between the two flower plate assemblies, and a resin filling port and a resin discharge port connected to the resin filling area are provided on the outer wall of the cylinder, the resin filling port is provided near the upper head, and the resin discharge port is provided near the lower head; valves are provided at the resin filling port and the resin discharge port, so that the resin can be replaced without disassembling the cylinder.

[0004] When the existing resin adsorption device is in use, the resin at the water inlet is in contact with high-concentration sewage, so the resin at the water inlet fails first, while the resin at the water outlet has not been fully utilized. Since the resin at the water inlet fails, it needs to be replaced. If all of them are replaced, it will cause a large waste. It is more troublesome to replace only the resin at the water inlet. Summary of the invention

[0005] The invention provides a softening water treatment device, aiming to solve the problem in the related art that the resin in the tank cannot be fully utilized and needs to be replaced.

[0006] A softened water treatment device, comprising a tank body. A water distribution pipe penetrating up and down is provided at the axis of the tank body. Two spiral blades are installed between the outer side of the water distribution pipe and the inner wall of the tank body, so that a spiral channel one and a channel two are formed between the two spiral blades. Resin particles are filled in the channel one and the channel two. The two ends of the channel one and the channel two are communicated with each other. A piston block is slidably connected in the water distribution pipe. A plurality of gate assemblies are arranged at equal intervals in the vertical direction on the water distribution pipe. A plurality of water outlet valves are installed in the vertical direction on the side surface of the tank body. The other ends of all the water outlet valves are communicated with the same confluence pipe. An L-shaped diversion hole is opened on the piston block. The top end of the diversion hole is communicated with the space above the piston block. When the piston block is aligned with the gate assembly, the gate assembly is opened so that the other end of the diversion hole is communicated with the channel one / channel two. A lifting assembly for controlling the lifting of the piston block is installed in the tank body, so that the gate assemblies are opened and closed sequentially from bottom to top. Each time a water outlet valve is opened, and the opened gate assembly and the water outlet valve are respectively located on the channel one and the channel two.

[0007] The effect is as follows: Inject the water to be treated into the water inlet pipe, and then enter the diversion hole through the water distribution pipe. Enter the channel one through the diversion hole and the opened gate assembly, forming two shunts flowing upward and downward respectively. The two shunts enter the channel two through the upper communication cavity and the lower communication cavity respectively, and then reach the opened water outlet valve along the channel two. After working for a period of time, make the piston block rise until the piston block abuts against the upper gate assembly and opens it, so that the upper communication hole is communicated with the diversion hole, and the bottom gate assembly disengages from the piston block and resets to close, so as to avoid excessive attachment of impurities to the resin particles at the water inlet, resulting in large flow pressure, and can make full use of the resin particles.

[0008] Preferably, the gate assembly includes an inclined chute opened on the water distribution pipe. A communication hole communicated with the channel one / channel two is opened on the inclined chute. A valve plate is slidably installed in the inclined chute. An elastic component for closing the communication hole by the valve is installed between the valve plate and the inclined chute. A one-way component is installed on the valve plate. When the top end of the piston block abuts against the one-way component and rises, the one-way component and the valve plate slide obliquely upward until the one-way component disengages from the top end of the piston block. When the bottom end of the piston block abuts against the one-way component and descends, the one-way component gives way to allow the piston block to pass through. When the piston block rises, the piston block abuts against the one-way component, thereby pushing the one-way component and the valve plate to slide obliquely upward to the right along the inclined chute until the right end of the diversion hole is communicated with the communication hole. After running for a period of time, the piston block rises, the one-way component disengages from the piston block, and the valve plate slides obliquely downward to the left to reset, thereby blocking the communication hole again.

[0009] Preferably, the elastic component includes a sliding rod slidably installed at the top of the inclined chute. A spring is installed on the sliding rod. The bottom end of the sliding rod abuts against the top of the valve plate. By the sliding rod abutting against the valve plate, the valve plate is located at the bottom of the inclined chute in the initial state.

[0010] Preferably, the one-way component includes a rotating bar hinged on the left side of the valve plate, a torsion spring for keeping the rotating bar horizontal is installed between the valve plate and the rotating bar, and a limit block abutting against the upper side of the rotating bar is provided on the inner side of the valve plate.

[0011] Preferably, a delay component is installed at the bottom of the piston block to keep the gate assembly open for a period of time after the piston block rises. The gate assembly is delayed in closing through the delay component, and water flows into channel one or channel two through the upper gate assembly. Finally, the adsorbed water is diverted to backwash the resin particles on the outside of the lower gate assembly.

[0012] Preferably, the delay assembly includes a vertical rod fixedly connected to the piston block, a sliding rod is slidably mounted on the vertical rod, the right sides of the sliding rod and the vertical rod are coplanar with the right side of the piston block, and a control assembly for controlling the sliding of the sliding rod is provided at the bottom of the sliding rod. When the piston block pushes the rotating bar and the gate assembly opens, the rotating bar in the lower gate assembly resists the sliding rod until the sliding rod slides upward and breaks contact with the rotating bar.

[0013] Preferably, a pneumatic chamber is provided at the bottom of the piston, and the control component includes a piston rod slidably installed in the pneumatic chamber, the piston rod is connected to the sliding rod, a part of the water flow entering the resin particles is discharged from the water outlet valve to complete the adsorption treatment, and the other branch flows out from the gate assembly below to complete the recoil of the resin particles near the gate assembly below. After the water flows into the bottom of the piston block, the pressure gradually increases, thereby causing the piston rod assembly to rise and reset until the sliding rod is separated from the rotating bar, the gate below is reset, and no recoil is performed.

[0014] Preferably, the lifting assembly includes a winding wheel rotatably mounted on the top of the inner part of the tank body, a pull rope is wound around the winding wheel, and the pull rope is connected to the piston block.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0016] 1. When the water inlet pressure increases and the water inlet position needs to be changed, the driving rod rotates to rotate the reel, and the pull rope is wound around the reel, so that the piston block rises until the piston block presses against the gate assembly above to open it, so that the upper connecting hole is connected with the diversion hole, and the gate assembly at the bottom is separated from the piston block and reset to close, so that the resin particles in each part are fully utilized.

[0017] 2. When the piston block moves upward, since the pressure at the bottom of the piston block becomes smaller, a part of the water flow entering the resin particles is discharged from the water outlet valve to complete the adsorption treatment, and the other part of the split flow flows out from the gate plate assembly below, to complete the backwashing of the resin particles near the gate plate assembly below. And due to the large pressure difference between the lower part of the piston block and Channel 1 / Channel 2, the impact force of the split flow is large, and the backwashing effect is good. After the water flow enters below the piston block, the pressure gradually increases, so that the piston rod assembly rises and resets until the sliding rod disengages from the rotating bar, and the gate plate below resets and no longer performs backwashing.

[0027] The embodiments of the present invention will be described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] As Figures 1 - 7As shown in the figure, a softened water treatment device includes a tank body 1, a water distribution pipe 2, two spiral blades 3, a piston block 4, a lifting assembly 5, a plurality of gate assemblies 6 and a plurality of water outlet valves 7. The water distribution pipe 2 is arranged at the axis inside the tank body 1. The top end of the water distribution pipe 2 is communicated with the water inlet pipe 11 of the tank body 1. The bottom end of the water distribution pipe 2 extends out of the bottom of the tank body 1 and is connected with a sewage discharge valve 12. The two spiral blades 3 are installed between the outer side of the water distribution pipe 2 and the inner wall of the tank body 1. A spiral channel one and a channel two are formed between the two spiral blades 3. A partition plate 13 is fixedly connected to the top end of the water distribution pipe 2. There is a certain distance between the partition plate 13 and the top ends of the two spiral blades 3 to form an upper communication cavity. There is a certain distance between the bottom ends of the two spiral blades 3 and the inner bottom of the tank body 1 to form a lower communication cavity. The upper communication cavity, the lower communication cavity, the channel one and the channel two are filled with resin particles. The plurality of gate assemblies 6 are arranged on the water distribution pipe 2 at equal intervals in the vertical direction. The piston block 4 is slidably installed in the water distribution pipe 2. The lifting assembly 5 is used to control the lifting of the piston block 4.

[0029] The cross-sectional shape of the piston block 4 is capsule-shaped, and the inner hole of the water distribution pipe 2 is also capsule-shaped. An L-shaped diversion hole 41 is opened on the piston block 4. The top end of the diversion hole 41 is communicated with the space above the piston block 4, and the other end is located on the right side of the piston block 4.

[0030] The gate assembly 6 includes an inclined chute 61, a communication hole 62, a valve plate 63, an elastic assembly 64 and a one-way assembly 65. The inclined chute 61 is opened on the inner right side wall of the water distribution pipe 2. The communication hole 62 is arranged in the inclined chute 61 and penetrates the wall of the water distribution pipe 2. A filter screen for preventing resin particles from passing through is arranged in the communication hole 62. The valve plate 63 is slidably installed in the inclined chute 61. When the valve plate 63 is located at the bottom of the inclined chute 61, it blocks the communication hole 62. The elastic assembly 64 is installed at the top inside the inclined chute 61, and the bottom end of the elastic assembly 64 abuts against the top of the valve plate 63, so that the valve plate 63 is located at the bottom of the inclined chute 61. The one-way assembly 65 is installed on the left side surface of the valve plate 63. When the piston block 4 rises, the piston block 4 abuts against the one-way assembly 65, thereby pushing the one-way assembly 65 and the valve plate 63 to slide right upward along the inclined chute 61 until the right end of the diversion hole 41 is communicated with the communication hole 62. After running for a period of time, the piston block 4 rises, the one-way assembly 65 disengages from the piston block 4, and the valve plate 63 slides left downward to reset, thereby blocking the communication hole 62 again.

[0031] The number of the water outlet valves 7 is six, which are divided into three groups, upper, middle and lower, with two in each group. The two water outlet valves 7 in each group of water outlet valves 7 are respectively communicated with the first channel and the second channel, and a filter screen is arranged at the connection part to prevent resin particles from entering the water outlet valves 7. The other ends of all the water outlet valves 7 are communicated with the same confluence pipe. Each two adjacent gate plate assemblies 6 are respectively communicated with the first channel and the second channel. When the gate plate assembly 6 communicated with the first channel is opened and the diversion hole 41 is communicated with the communication hole 62 of the first channel, and if the opened gate plate assembly 6 is located below the water distribution pipe 2, then the water outlet valve 7 communicated with the second channel in the upper group is opened, and the other water outlet valves 7 are closed. If the opened gate plate assembly 6 is located in the middle of the water distribution pipe 2, then the water outlet valve 7 communicated with the second channel in the middle group is opened, and the other water outlet valves 7 are closed. If the opened gate plate assembly 6 is located above the water distribution pipe 2, then the water outlet valve 7 communicated with the second channel in the lower group is opened, and the other water outlet valves 7 are closed. And so on. When the gate plate assembly 6 communicated with the second channel is opened, then according to the position of the opened gate plate assembly 6 relative to the water distribution pipe 2, the corresponding water outlet valve 7 communicated with the first channel is opened, and the other water outlet valves 7 are closed. When set in this way, the water flow entering the gate plate assembly 6 will be divided into two streams, moving in different directions from the first channel and the second channel to the position of the opened water outlet valve 7, so that the distances traveled by the two water streams are basically the same, and the adsorption treatment effects are basically the same.

[0032] The elastic component 64 includes a sliding rod 641 and a spring 642. The sliding rod 641 is slidably installed at the top of the inclined chute 61, and the spring 642 is installed between the sliding rod 641 and the inclined chute 61. The bottom end of the sliding rod 641 abuts against the top of the valve plate 63.

[0033] The one-way component 65 includes a rotating bar 651 and a torsion spring 652. The rotating bar 651 is hinged to the left side of the valve plate 63. A limiting block that abuts against the upper side of the rotating bar 651 is arranged on the left side of the valve plate 63 to limit the clockwise rotation of the rotating bar 651. When it rotates to the horizontal position by itself, it cannot continue to rotate clockwise. The torsion spring 652 is installed between the valve plate 63 and the rotating bar 651 to keep the rotating bar 651 horizontal.

[0034] The lifting component 5 includes a winding wheel 51, a driving rod 52 and a pulling rope 53. The winding wheel 51 is rotatably installed at the inner top end of the tank body 1. One end of the pulling rope 53 is fixed and wound around the winding wheel 51, and the other end is connected to the piston block 4. A driving rod 52 is connected to the central axis of the winding wheel 51. One end of the driving rod 52 penetrates through the tank body 1 and is connected with a driving source (the driving source can be a motor or a manual handwheel).

[0035] Working principle: Inject the water to be treated into the water inlet pipe 11, then enter the diversion holes 41 through the water distribution pipe 2, enter the first channel through the diversion holes 41 and the opened gate assembly 6, forming two shunts flowing upward and downward respectively. The two shunts enter the second channel through the upper communication cavity and the lower communication cavity respectively, then reach the opened water outlet valve 7 along the second channel, and finally enter the confluence pipe through the water outlet valve 7 and are discharged. After working for a period of time, due to the accumulation of more impurities in the resin particles at the communication holes 62, it is necessary to change the water inlet position. The driving rod 52 rotates to make the winding wheel 51 rotate, and the pull rope 53 winds around the winding wheel 51, so that the piston block 4 rises until the piston block 4 abuts against the upper gate assembly 6 to open it, making the upper communication hole 62 communicate with the diversion hole 41, and the bottom gate assembly 6 disengages from the piston block 4 and resets to close, so as to avoid excessive attachment of impurities to the resin particles at the water inlet resulting in high flow pressure, and enable the resin particles to be fully utilized.

[0036] In order to realize backwashing, a delay component 8 for keeping the gate assembly 6 open for a period of time after the piston block 4 rises is installed at the bottom of the piston block 4;

[0037] The delay component 8 includes a vertical rod 81, a sliding rod 82, a pneumatic cavity and a piston rod 83. The vertical rod 81 is fixedly connected to the piston block 4. The sliding rod 82 is slidably installed up and down on the vertical rod 81, and the right sides of the sliding rod 82 and the vertical rod 81 are coplanar with the right side of the piston block 4. A pneumatic cavity is opened at the bottom of the piston. The piston rod 83 is hermetically slidably installed in the pneumatic cavity, and the bottom end of the piston rod 83 is fixedly connected to the sliding rod 82. When the piston block 4 moves upward, due to the decrease in the pressure at the bottom of the piston block 4, the piston rod 83 slides downward relative to the piston block 4, so that the right side of the sliding rod 82 abuts against the rotating bar 651 to prevent the valve plate 63 from sliding downward to close the communication hole 62. The top end of the piston block 4 abuts against the upper gate assembly 6 to open the gate assembly 6. The water to be treated flows into the first channel or the second channel through the upper gate assembly 6. Since two adjacent gate assemblies 6 are connected to different spiral channels, part of the water flow entering the resin particles is discharged from the water outlet valve 7 to complete the adsorption treatment, and the other shunt flows out from the lower gate assembly 6 to complete the backwashing of the resin particles near the lower gate assembly 6. And due to the large pressure difference between the lower part of the piston block 4 and the first channel / the second channel, the impact force of the shunt is large and the backwashing effect is good. After the water flow flows into the lower part of the piston block 4, the pressure gradually increases, so that the piston rod 83 rises and resets until the sliding rod 82 disengages from the rotating bar 651, and the lower gate resets and no longer performs backwashing.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
