Description

Technical Field

[0001] This invention relates to the field of activated carbon water treatment, and more particularly to an intelligent thermal disinfection activated carbon water treatment device and control system. Background Technology

[0002] Activated carbon granules are widely used in water treatment to remove organic matter, residual chlorine, odors, and some heavy metal pollutants due to their high adsorption and filtration performance. Traditional activated carbon water treatment devices use activated carbon granules to filter water flow and periodically backwash to remove impurities attached to the surface of the activated carbon granules to restore their adsorption capacity. However, traditional processes usually only use backwashing at room temperature, which poses a risk of microbial growth because the pores of activated carbon can become breeding grounds for microorganisms. To overcome this problem, modern improved processes have introduced thermal disinfection technology. By backwashing with 80-90°C hot water from bottom to top, impurities on the surface of the granules can be effectively removed. It can kill more than 99% of microorganisms in the pores. This process is achieved through intelligent control of the backwash valve, which regulates the direction of water flow: during filtration, water flows from top to bottom into the device; during backwashing and disinfection, hot water is injected into the bottom of the device and treats the activated carbon particles from bottom to top. Nevertheless, after long-term use, activated carbon particles are prone to caking or deep impurities, which can hinder water flow, especially the upper activated carbon. Due to the decrease in water pressure, it is difficult to be fully flushed, resulting in low efficiency. In addition, the backwash water pressure is unevenly distributed, making it difficult to act on activated carbon particles in different layers simultaneously, further reducing the backwashing effect. Summary of the Invention

[0003] To overcome the shortcomings mentioned in the background art, the present invention provides an intelligent thermal disinfection activated carbon water treatment device and control system.

[0004] The technical solution of the present invention is as follows: an intelligent thermal disinfection activated carbon water treatment device and control system, including a backwash valve disposed on the upper side of the tank, the tank being provided with a control terminal, the backwash valve being electrically connected to the control terminal, the backwash valve being connected to an inlet pipe, an outlet pipe, a drain pipe and a water distributor, the inlet pipe, the outlet pipe and the drain pipe being located outside the tank, the water distributor being located inside the tank, an inner liner being fixedly connected inside the tank, a filter plate being fixedly connected to the lower side of the inner liner, the water distributor passing through the filter plate, and activated carbon particles being placed inside the inner liner.

[0005] The inner liner is provided with two sets of first holes symmetrically distributed, and each set of first holes has several holes distributed vertically. There is a gap between the inner liner and the inner wall of the tank.

[0006] To further explain, the inner liner and the tank body are jointly fixed by symmetrically distributed fasteners, the inner liner is rotatably connected to a pressing member, the pressing member is provided with symmetrically distributed pressing parts, and the pressing parts are used to seal the adjacent group of first holes.

[0007] To further explain, the inner liner is composed of multiple pipes arranged from top to bottom, with the inner and outer diameters of all pipes decreasing sequentially from top to bottom.

[0008] To further explain, the tank is equipped with a reciprocating motor that is electrically connected to the control terminal. The output shaft of the reciprocating motor passes through the tank and is fixedly connected to the water distributor. The output shaft of the motor is rotatably and sealed to the tank. The water distributor is fixedly connected to a connecting rod, which is fixedly connected to the extrusion component.

[0009] To further explain, the water distributor is slidably connected to symmetrically distributed sliding tubes, the sliding tubes are connected to the water distributor, the water distributor is connected to the tank body through the sliding tubes, and an elastic element is fixedly connected between the sliding tubes and the water distributor.

[0010] To further explain, the sliding tube is provided with a pressure-bearing part.

[0011] To further explain, the axis of the sliding tube passes through the side of the extrusion section near the adjacent fixing member.

[0012] To further explain, the inner liner is internally rotatably connected to a storage shell that is rotatably connected to the water distributor. The storage shell divides the inner liner into two parts from top to bottom. The storage shell has symmetrically distributed chambers and several second holes. The second holes are used to connect the inner liner and adjacent chambers. The activated carbon particles inside the inner liner are located outside the storage shell. The upper side of the storage shell has a through hole, the diameter of which is smaller than the diameter of the second holes.

[0013] To further explain, the storage shell is located between the two sets of the first holes.

[0014] To further clarify, the contact surfaces between the water distributor and the storage shell are both friction surfaces.

[0015] Compared with the prior art, the present invention has the following advantages: The present invention simultaneously flushes the activated carbon particles in each layer of the inner tank by squeezing clean hot water into the first holes of each layer of the inner tank. This causes all activated carbon particles to flow due to the clean hot water, enhancing the fluidity of the upper activated carbon particles during flushing, thereby improving the cleaning effect on the activated carbon particles. Furthermore, the second holes at different heights directly collect debris and impurities from the activated carbon particles in the same layer, shortening the path required for debris and impurities to be collected. This allows impurities and particles in the lower activated carbon particles to flow directly upward through the chamber, reducing the probability of debris and impurities being blocked, thereby improving the efficiency of collecting debris and impurities during activated carbon backwashing. At the same time, the shaking of the storage shell assists the movement of the activated carbon particles, making it easier to discharge debris and impurities accumulated in the multi-layer activated carbon particles, thus improving the cleaning effect on debris and impurities in the activated carbon particles.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0027] Example 1: This example discloses an intelligent thermal disinfection activated carbon water treatment device and control system, which is used to enhance the backwashing effect of activated carbon.

[0028] like Figures 1-6 and Figure 9 As shown, the backwash valve 2 is located on the upper side of the tank body 1. The tank body 1 is equipped with a control terminal (not shown in the figure). The backwash valve 2 is electrically connected to the control terminal and is used to control the flow direction of the liquid inside the backwash valve 2. The backwash valve 2 is an existing structure, and its internal structure is not shown in the figure. The backwash valve 2 is connected to an inlet pipe 201, an outlet pipe 202, a drain pipe 203, and a water distributor 204. Both the outlet pipe 202 and the drain pipe 203 are connected to water pumps (not shown in the figure) for cleaning the outlet pipe 202 and the drain pipe 203. The water in tank 3 is drawn out. Under normal conditions, when water filtration is required, the water flows through the inlet pipe 201 into the backwash valve 2, and then the water flows out from the backwash valve 2 into the tank 1. After being filtered by activated carbon particles in the inner tank 3, the water pump draws water from the tank 1 through the outlet pipe 202 and the water distributor 204. The water is drawn out from the bottom of the water distributor 204 to the outlet pipe 202. When backwashing of the activated carbon particles is required, clean hot water flows sequentially through the inlet pipe 201 and the backwash valve 2 into the bottom of the water distributor 204. In this embodiment, hot water flows upwards from the bottom and impacts the activated carbon particles inside the inner tank 3. A water pump draws hot water from the tank 1 through the drain pipe 203 and backwash valve 2. The hot water is continuously discharged through the backwash valve 2 and drain pipe 203. The inlet pipe 201, outlet pipe 202, and drain pipe 203 are all located outside the tank 1. The water distributor 204 is located inside the tank 1. The inner tank 3 is fixedly connected inside the tank 1, and a filter plate is fixedly connected to the lower side of the inner tank 3. The water distributor 204 passes through the filter plate. In this embodiment, activated carbon particles are placed inside the inner tank 3. The inner tank 3 is provided with two sets of first holes 301 symmetrically distributed on the left and right. Each set of first holes 301 has several holes distributed vertically. The upper part of the inner tank 3 is sealed and fitted to the tank body 1. There is a gap between the inner tank 3 and the inner wall of the tank body 1. When the cleaning hot water impacts the activated carbon particles of the inner tank 3 from the bottom upward, some of the cleaning hot water will flow upward through the gap between the inner tank 3 and the tank body 1. Then the water flow enters the activated carbon particles of the inner tank 3 through different first holes 301, so that the cleaning hot water directly washes the upper activated carbon particles.

[0029] like Figure 4 , Figure 5 and Figure 7As shown, the inner liner 3 and the tank body 1 are fixedly connected by two symmetrically distributed fasteners 4. The inner liner 3 is rotatably connected to an extrusion member 5. The extrusion member 5 is provided with two symmetrically distributed extrusion parts 501. When water needs to be filtered initially, the extrusion parts 501 block the adjacent first hole 301, and the water flow will not flow into the gap between the inner liner 3 and the tank body 1. When the activated carbon particles need to be backwashed, the extrusion member 5 drives the two extrusion parts 501 on it to rotate, and the extrusion parts 501 lose contact with the adjacent first hole 301, so that the first hole 301 is no longer blocked.

[0030] like Figure 2 As shown, the inner tank 3 is composed of multiple pipes arranged from top to bottom. The inner and outer diameters of all pipes decrease sequentially from top to bottom. As clean hot water is continuously discharged from the bottom and replenished into the gap between the inner tank 3 and the tank body 1, the squeezing part 501 squeezes the clean hot water between it and the fixing part 4, thereby increasing the water flow pressure between the upper part of the inner tank 3 and the tank body 1.

[0031] like Figure 6 , Figure 7 and Figure 9 As shown, a reciprocating motor 6 electrically connected to a control terminal is installed in the tank body 1. The output shaft of the reciprocating motor 6 passes through the tank body 1 and is fixedly connected to the water distributor 204. The output shaft of the motor 6 is rotatably connected to the tank body 1 in a sealed manner. A connecting rod 7 is fixedly connected to the water distributor 204. The connecting rod 7 is fixedly connected to the extruder 5. When it is necessary to backwash the activated carbon particles, the output shaft of the reciprocating motor 6 drives the extruder 5 to reciprocate through the water distributor 204 and the connecting rod 7.

[0032] like Figure 7 and Figure 8 As shown, the water distributor 204 is slidably connected to a sliding tube 8 that is symmetrically distributed on the left and right sides. The sliding tube 8 is connected to the water distributor 204, and the water distributor 204 is connected to the tank body 1 through the sliding tube 8. An elastic element, which is a compression spring, is fixed between the sliding tube 8 and the water distributor 204.

[0033] like Figure 8 As shown, the sliding tube 8 is provided with a pressure-bearing part 801, and the inner diameter of the pressure-bearing part 801 is smaller than the inner diameter of the sliding tube 8 near the axis of the water distributor 204.

[0034] like Figure 7 As shown, the axis of the sliding tube 8 passes through the side of the extrusion part 501 near the adjacent fixing member 4, and is used to accurately inject clean hot water into the contact surface between the fixing member 4 and the extrusion part 501.

[0035] The working principle is as follows:

[0036] When the operator needs to use this device for water treatment, the operator injects the water to be treated into the inlet pipe 201. The water flows through the inlet pipe 201 into the backwash valve 2. The operator opens the backwash valve 2 through the control terminal, and the water flows out from the backwash valve 2 into the tank 1. The water flows through the activated carbon particles in the tank 1 for filtration (at this time, the squeezing part 501 blocks the adjacent first hole 301, and the water will not flow out from the first hole 301). The water pump draws water from the tank 1 through the outlet pipe 202, the backwash valve 2, and the water distributor 204. The water that has been filtered by the activated carbon particles is drawn out to the backwash valve 2 through the sliding pipe 8 and the water distributor 204. The backwash valve 2 discharges the filtered water through the outlet pipe 202.

[0037] When backwashing activated carbon granules is required, the operator controls backwash valve 2 via the control terminal, adjusting the flow direction of the liquid within backwash valve 2 (initially, when water filtration is required, the water flow direction is: inlet pipe 201, backwash valve 2, tank 1, water distributor 204, backwash valve 2, outlet pipe 202; when backwashing activated carbon granules is required, the clean hot water flow direction is: inlet pipe 201, backwash valve 2, water distributor 204, tank 1, backwash valve 2, drain pipe 203). The operator injects clean hot water into inlet pipe 201, and the clean hot water flows through inlet pipe 201 and backwash valve 202. 2. Entering the bottom of the water distributor 204, the operator starts the reciprocating motor 6 through the control terminal. The output shaft of the reciprocating motor 6 first drives the extrusion component 5 to rotate through the water distributor 204 and the connecting rod 7. The extrusion component 5 drives the two extrusion sections 501 to rotate. The extrusion sections 501 no longer block the adjacent set of first holes 301, so that part of the clean hot water impacts the activated carbon particles in the inner tank 3 from the bottom upwards, and the other part of the clean hot water enters the gap between the inner tank 3 and the tank body 1. The clean hot water in the gap enters the space between the extrusion section 501 and the adjacent fixing component 4. The clean hot water enters the inner tank 3 through all the first holes 301.

[0038] As the hot water enters the inner tank 3 through all the first holes 301, the output shaft of the reciprocating motor 6 drives the extruder 5 to reverse through the connecting rod 7. The extruder 5 extrudes the hot water between itself and the fixing member 4, increasing the pressure of the hot water between the extruder 5 and the adjacent fixing member 4. The hot water is then assisted in being squeezed into all the first holes 301. The hot water enters the inner tank 3 and washes the activated carbon particles in each layer. After the hot water washes the activated carbon particles, the used hot water is extracted through the backwash valve 2 and the drain pipe 203.

[0039] During the reciprocating rotation of the output shaft of the reciprocating motor 6, the output shaft of the reciprocating motor 6 drives the water distributor 204 to rotate reciprocally. The water distributor 204 drives all the sliding tubes 8 to rotate. The clean hot water discharged from the water distributor 204 squeezes the pressure receiving part 801. The pressure receiving part 801 is compressed and moves, which helps the sliding tube 8 move away from the axis of the water distributor 204. During the process of the sliding tube 8 moving away from the axis of the water distributor 204, the elastic element between the sliding tube 8 and the water distributor 204 is contracted, so that the sliding tube 8 is closer to the squeezing part 5 and the adjacent fixed part 4, and the clean hot water is better discharged between the squeezing part 5 and the adjacent fixed part 4. Through the squeezing force generated by the squeezing part 5 and the adjacent fixed part 4 on the clean water, the clean hot water is squeezed into the first hole 301 of each layer in the inner tank 3, and the activated carbon particles of each layer in the inner tank 3 are simultaneously flushed, so that all activated carbon particles are driven by the clean hot water to generate flow, which enhances the fluidity of the upper activated carbon particles when being flushed, thereby improving the cleaning effect of the activated carbon particles.

[0040] When it is necessary to stop using this device, the control terminal controls the output shaft of the reciprocating motor 6 to rotate and drive the extrusion part 5 to reset, so that the extrusion part 501 and the adjacent fixing part 4 are in contact. The control terminal controls the flow direction in the backwash valve 2 to return to the initial state when the water is filtered, that is, the water flow direction is inlet pipe 201, backwash valve 2, inside tank 1, water distributor 204, backwash valve 2, outlet pipe 202. Finally, the operator closes the backwash valve 2 and the reciprocating motor 6 through the control terminal.

[0041] Example 2: This example discloses an intelligent thermal disinfection activated carbon water treatment device and control system, which is a further improvement on Example 1.

[0042] like Figure 1 , Figure 5 and Figure 6As shown, the upper part of the tank 1 is a detachable lid for easy cleaning of the inside of the tank 1. The inner liner 3 is rotatably connected to a storage shell 9 that is rotatably connected to the water distributor 204 for easy cleaning of the inside of the storage shell 9. The storage shell 9 divides the inner liner 3 into left and right parts from top to bottom. The storage shell 9 has symmetrically distributed chambers 901 inside and several second holes 902 for connecting the inner liner 3 and adjacent chambers 901. In the above embodiment, the activated carbon particles are located inside the inner liner 3. In this embodiment, the activated carbon particles inside the inner liner 3 are located inside the storage shell 3. Outside the storage shell 9, during backwashing of activated carbon particles, debris and impurities flushed out of the activated carbon particles enter the chamber 901 through the second hole 902 for collection. The contact surfaces between the water distributor 204 and the storage shell 9 are friction surfaces. When the activated carbon particles between the storage shell 9 and the inner liner 3 move due to the impact of clean hot water, the output shaft of the reciprocating motor 6 drives the water distributor 204 to rotate. The water distributor 204 drives the storage shell 9 to shake through friction, assisting the movement of the activated carbon particles. A through hole is provided on the upper side of the storage shell 9, and the diameter of the through hole is smaller than the diameter of the second hole 902.

[0043] like Figure 5 and Figure 6 As shown, the storage shell 9 is located between the two sets of first holes 301 on the left and right. After the cleaning hot water enters the first hole 301, the cleaning hot water washes the activated carbon particles and flushes the debris and impurities into the storage shell 9 through all the second holes 902.

[0044] The working principle of this embodiment follows that of Embodiment 1, and is as follows:

[0045] During the process of hot water entering the inner tank 3 and rinsing the activated carbon particles in each layer, the debris and impurities washed down from the activated carbon particles in different layers enter the chamber 901 through the adjacent second holes 902. The hot water is discharged from the chamber 901 through the through hole on the upper side of the storage shell 9. The through hole on the upper side of the storage shell 9 blocks the debris and impurities. The second holes 902 at different heights directly collect the debris and impurities of the activated carbon particles in the same layer, shortening the path required for the debris and impurities to be collected. This allows the impurities and particles in the lower layer of activated carbon particles to flow directly upward through the chamber 901, reducing the probability of debris and impurities being blocked, thereby improving the efficiency of collecting debris and impurities during activated carbon backwashing. During the reciprocating rotation of the output shaft of the reciprocating motor 6, the output shaft of the reciprocating motor 6 drives the water distributor 204 to rotate. The water distributor 204 drives the storage shell 9 to shake through friction, assisting the movement of the activated carbon particles, so that the debris and impurities accumulated in the multi-layer activated carbon particles are more easily discharged, improving the cleaning effect of debris and impurities in the activated carbon particles.

[0046] When it is necessary to stop using this device, the control terminal controls the output shaft of the reciprocating motor 6 to rotate and drive the extrusion part 5 to reset, so that the extrusion part 501 and the adjacent fixing part 4 are in contact. The control terminal controls the flow direction in the backwash valve 2 to return to the initial state when the water is filtered, that is, the water flow direction is inlet pipe 201, backwash valve 2, inside tank 1, water distributor 204, backwash valve 2, outlet pipe 202. The operator closes the backwash valve 2 and the reciprocating motor 6 through the control terminal, and finally opens the cover of tank 1, takes out the storage shell 9, and cleans the inside of tank 1 and storage shell 9.

[0047] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.
