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 softening water treatment device comprises a tank body, wherein a water distribution pipe which passes through the tank body from top to bottom 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 1 and a channel 2 are formed between the two spiral blades, the channel 1 and the channel 2 are filled with resin particles, the two ends of the channel 1 and the channel 2 are connected, 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 of the tank body, the other ends of all the water outlet valves are connected to the same manifold, an L-shaped guide hole is provided on the piston block, the top of the guide hole is connected to the space above the piston block, when the piston block is aligned with the gate assembly, the gate assembly is opened to connect the other end of the guide hole with the channel 1 / channel 2, a lifting assembly for controlling the lifting of the piston block is installed in the tank body, so that the gate assembly is opened and closed from bottom to top in sequence, one water outlet valve is opened each time, and the opened gate assembly is respectively located on the channel 1 and the channel 2.

[0007] The effect is as follows: the water to be treated is injected into the water inlet pipe, then enters the guide hole through the water distribution pipe, enters channel one through the guide hole and the opened gate assembly, and forms two branches that flow upward and downward respectively. The two branches enter channel two through the upper connecting cavity and the lower connecting cavity respectively, and then reach the opened water outlet valve along channel two. After working for a period of time, the piston block rises until the piston block presses against the upper gate assembly to open it, so that the upper connecting hole is connected with the guide hole, and the gate assembly at the bottom is separated from the piston block and reset to close, so as to avoid excessive impurities attached to the resin particles at the water inlet, resulting in high circulation pressure, and the resin particles can be fully utilized.

[0008] Preferably, the gate assembly includes an inclined slide groove provided on the water distribution pipe, the inclined slide groove is provided with a connecting hole connected to channel one / channel two, a valve plate is slidably installed in the inclined slide groove, an elastic component for causing the valve to close the connecting hole is installed between the valve plate and the inclined slide groove, and a one-way component is installed on the valve plate. When the top end of the piston block rises against the one-way component, the one-way component and the valve plate slide obliquely upward until the one-way component is separated from the top end of the piston block. When the bottom end of the piston block falls against the one-way component, the one-way component gives way to allow the piston block to pass. When the piston block rises, the piston block against the one-way component, thereby pushing the one-way component and the valve plate to slide to the upper right along the inclined slide groove until the right end of the guide hole is connected to the connecting hole. After running for a period of time, the piston block rises, the one-way component is separated from the piston block, and the valve plate slides to the lower left and resets, thereby blocking the connecting hole again.

[0009] Preferably, the elastic component includes a sliding rod slidably installed on the top of the inclined slide groove, a spring is installed on the sliding rod, the bottom end of the sliding rod is abutted against the top of the valve plate, and the sliding rod is pressed against the valve plate so that the valve plate is located at the bottom of the inclined slide groove in the initial state.

[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: 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.

[0016] 2. When the piston block moves upward, due to the decrease in pressure at the bottom of the piston block, part of the water flow entering the resin particles is discharged from the water outlet valve to complete the adsorption process, and the other branch flows out from the gate assembly below to complete the recoil on the resin particles near the gate assembly below. In addition, due to the large pressure difference between the bottom of the piston block and channel one / channel two, the impact force of the branch flow is large and the recoil effect is good. After the water flows into the bottom of the piston block, the pressure gradually increases, causing the piston rod assembly to rise and reset until the slide bar is separated from the rotating bar, the gate below is reset, and no recoil is performed.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figure 1-Figure 7As shown, a softening water treatment equipment 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, wherein the water distribution pipe 2 is arranged at the axis in the tank body 1, the top end of the water distribution pipe 2 is connected 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 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, and a spiral channel 1 and a channel 2 are formed between the two spiral blades 3, a partition 13 is fixedly connected to the top end of the water distribution pipe 2, a certain distance is formed between the partition 13 and the top ends of the two spiral blades 3 to form an upper connecting cavity, a certain distance is formed between the bottom ends of the two spiral blades 3 and the inner bottom of the tank body 1 to form a lower connecting cavity, the upper connecting cavity, the lower connecting cavity, the channel 1 and the channel 2 are filled with resin particles, a 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, and the lifting assembly 5 is used to control the lifting and lowering of the piston block 4.

[0027] The cross-section 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 guide hole 41 is opened on the piston block 4. The top of the guide hole 41 is connected to the space above the piston block 4, and the other end is located on the right side of the piston block 4.

[0028] The gate assembly 6 includes an inclined slide 61, a connecting hole 62, a valve plate 63, an elastic component 64 and a one-way component 65. The inclined slide 61 is opened on the inner right wall of the water distribution pipe 2. The connecting hole 62 is arranged in the inclined slide 61 and penetrates the wall of the water distribution pipe 2. A filter screen is arranged in the connecting hole 62 to prevent resin particles from passing through. The valve plate 63 is slidably installed in the inclined slide 61. When the valve plate 63 is located at the bottom of the inclined slide 61, the connecting hole 62 is blocked. The elastic component 64 is installed at the top of the inclined slide 61, and the bottom end of the elastic component 64 It abuts against the top of the valve plate 63, so that the valve plate 63 is located at the bottom of the inclined groove 61, and the one-way component 65 is installed on the left side of the valve plate 63. When the piston block 4 rises, the piston block 4 abuts against the one-way component 65, thereby pushing the one-way component 65 and the valve plate 63 to slide to the upper right along the inclined groove 61 until the right end of the guide hole 41 is connected with the connecting hole 62. After running for a period of time, the piston block 4 rises, the one-way component 65 is separated from the piston block 4, and the valve plate 63 slides to the lower left and resets, thereby blocking the connecting hole 62 again.

[0029] There are six water outlet valves 7, which are divided into three groups of upper, middle and lower, two in each group of water outlet valves 7. The two water outlet valves 7 in each group of water outlet valves 7 are connected to channel one and channel two, respectively, and a filter screen is provided at the connection to prevent resin particles from entering the water outlet valve 7. The other ends of all water outlet valves 7 are connected to the same manifold, and every two adjacent gate assemblies 6 are connected to channel one and channel two, respectively. When the gate assembly 6 connected to channel one is opened, the guide hole 41 is connected to the connecting hole 62 of channel one, and if the opened gate assembly 6 is located at the lower part of the water distribution pipe 2, the water outlet valve 7 in the upper group connected to channel two is opened, and the other water outlet valves 7 are closed. If the opened gate assembly 6 is located in the middle of the water distribution pipe 2, , then the outlet valve 7 in the middle group connected to channel two is opened, and the other outlet valves 7 are closed. If the opened gate assembly 6 is located on the upper part of the water distribution pipe 2, the outlet valve 7 in the lower group connected to channel two is opened, and the other outlet valves 7 are closed. And so on, when the gate assembly 6 connected to channel two is opened, then according to the position of the opened gate assembly 6 relative to the water distribution pipe 2, the corresponding outlet valve 7 connected to channel one is opened, and the other outlet valves 7 are closed. When it is arranged in this way, the water flow entering the gate assembly 6 will be divided into two streams, moving from different directions of channel one and channel two to the position of the opened outlet valve 7, so that the distances flowed by the two water streams are basically the same, and the adsorption treatment effects are basically the same.

[0030] The elastic component 64 includes a sliding rod 641 and a spring 642 . The sliding rod 641 is slidably installed on the top of the inclined slide groove 61 , and the spring 642 is installed between the sliding rod 641 and the inclined slide groove 61 . The bottom end of the sliding rod 641 abuts against the top of the valve plate 63 .

[0031] The one-way component 65 includes a rotating bar 651 and a torsion spring 652. The rotating bar 651 is hinged on the left side of the valve plate 63. A limit block is provided on the left side of the valve plate 63 to abut against the upper side of the rotating bar 651, which is used to limit the clockwise rotation of the rotating bar 651. When it rotates to its own level, 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.

[0032] The lifting assembly 5 includes a winding wheel 51, a driving rod 52 and a pull rope 53. The winding wheel 51 is rotatably installed at the top of the tank body 1. One end of the pull rope 53 is fixed and wound around the winding wheel 51, and the other end is connected to the piston block 4. The driving rod 52 is connected to the central axis of the winding wheel 51. One end of the driving rod 52 passes through the tank body 1 and is connected to a driving source (the driving source can be a motor or a manual crank).

[0033] Working principle: the water to be treated is injected into the water inlet pipe 11, and then enters the guide hole 41 through the water distribution pipe 2, and enters the channel one through the guide hole 41 and the opened gate assembly 6, forming two branches that flow upward and downward respectively. The two branches enter the channel two through the upper connecting cavity and the lower connecting cavity respectively, and then reach the opened water outlet valve 7 along the channel two, and finally enter the conduit through the water outlet valve 7 for discharge. After working for a period of time, since the resin particles at the connecting hole 62 accumulate more impurities, it is necessary to change the water inlet position, the driving rod 52 rotates to rotate the winding wheel 51, and the pull rope 53 is wound around the winding wheel 51, so that the piston block 4 rises until the piston block 4 presses against the upper gate assembly 6 to open it, so that the upper connecting hole 62 is connected with the guide hole 41, and the bottom gate assembly 6 is separated from the piston block 4 and reset to close, so as to avoid excessive impurities attached to the resin particles at the water inlet, resulting in high circulation pressure, and the resin particles can be fully utilized.

[0034] In order to achieve backwashing, a delay component 8 is installed at the bottom of the piston block 4 to keep the gate assembly 6 open for a period of time after the piston block 4 rises; The delay assembly 8 includes a vertical rod 81, a sliding rod 82, an air pressure chamber and a piston rod 83. The vertical rod 81 is fixedly connected to the piston block 4. The sliding rod 82 is slidably installed on the vertical rod 81 up and down, 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. An air pressure chamber is provided at the bottom of the piston. The piston rod 83 is sealingly slidably installed in the air pressure chamber. The bottom end of the piston rod 83 is fixedly connected to the sliding rod 82. When the piston block 4 moves upward, the pressure at the bottom of the piston block 4 decreases, so that 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 connecting hole 62. The top of the piston block 4 abuts against the gate assembly 6 above. The gate assembly 6 is opened, and the water flow to be treated flows into channel one or channel two through the upper gate assembly 6. Since the 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 branch flows out from the lower gate assembly 6 to complete the recoil of the resin particles near the lower gate assembly 6. Since the pressure difference between the bottom of the piston block 4 and channel one / channel two is large, the impact force of the branch flow is large and the recoil effect is better. After the water flow flows into the bottom of the piston block 4, the pressure gradually increases, so that the piston rod 83 rises and resets until the slide bar 82 is separated from the rotating bar 651, and the lower gate is reset, and no recoil is performed.

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
