DETAILED DESCRIPTION

[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Reference Figure 1 The utility model provides a water quality stabilization and purification device. The device includes a shell 1, a backwashing mechanism, a filtering mechanism, a magnetic box 4, a differential pressure meter and a water quality monitor 6. Among them, a water inlet 2 is provided on the upper part of the side wall of the shell 1, and a water outlet 3 is provided on the lower part of the side wall of the shell 1. The water inlet 2 and the water outlet 3 are both connected to the differential pressure meter, and the differential pressure meter is connected to the control device. The pressure difference between the water inlet 2 and the water outlet 3 is used to judge whether the filtering mechanism is blocked and needs to be cleaned. A water quality monitor 6 is provided at the water outlet 3 to judge whether the water coming out of the water outlet 3 meets the requirements, and can make relevant adjustments according to the data in time to reduce excess losses and unnecessary waste. A filtering mechanism is provided in the shell 1 to filter the water coming in from the water inlet 2. A magnetic box 4 is provided below the filtering mechanism to magnetize the filtered water to reduce the activity of metal ions in the water. A drain pipe 7 is provided at the lower part of the housing 1, and a drain valve 8 is provided on the drain pipe 7. The backwashing mechanism is connected to the filter mechanism and the drain pipe 7 to discharge the dirt in the filter mechanism through the drain pipe 7. The drain valve 8 of the utility model is an electric drain valve 8 and / or a manual drain valve 8. The electric drain valve 8 is connected to the control device, and transmits information to the control device through the differential pressure meter to determine whether the filter mechanism is blocked. If blocked, the electric drain valve 8 is controlled by the control device to open to backwash the filter device.

[0026] The utility model is provided with a pressure differential meter (i.e., pressure transmitter) with a digital display function, which digitally indicates the real-time pressure differential between the inlet and outlet of the equipment. When the pressure differential is greater than the preset rated value, the equipment emits an audible and visual alarm. When the pressure differential is greater than the preset rated value, the backwashing mechanism automatically works, and when the pressure differential is less than the preset rated value, the backwashing mechanism automatically stops working, so that the equipment is always in a safe and reliable state, ensuring stable water supply of the water supply system.

[0027] When circulating water passes through the magnetic box, it is magnetized by the magnetic field, which affects the hardness of the water itself. However, this effect cannot be quickly and directly manifested. Therefore, in order to quickly and accurately monitor the changes in water hardness in real time, a water quality monitor is added to monitor the hardness of the circulating water in the equipment in real time. The water quality monitor adopts the water hardness selective electrode method (ISE method) imported from the United States, which has high sensitivity, rapid signal response, accurate measurement, stable performance, and simple maintenance. Through this equipment, the real-time situation of water hardness can be observed quickly and accurately, which is conducive to analyzing water quality and timely feedback of water quality to the operator, so that the operator can understand the current water quality and make relevant adjustments according to the data in time, reducing excess losses and unnecessary waste, reducing the cost of long-term operation, and improving work efficiency.

[0028] Specifically, the filter mechanism includes an upper filter plate 9, a lower filter plate 10, and a plurality of filter columns 11 disposed between the upper filter plate 9 and the lower filter plate 10. The upper filter plate 9 is provided with filter holes connected to the filter columns 11, and the lower filter plate 10 is provided with through holes connected to the magnetic box 4. Among them, the plurality of filter columns 11 are evenly arranged on one or two circumferences between the upper filter plate 9 and the lower filter plate 10, the number of filter holes on the upper filter plate 9 is consistent with the number of filter columns 11, and the positions of the filter holes also correspond to the positions of the filter columns 11. Specifically, see Figure 2 The filter column 11 includes a plurality of stainless steel wires 111 with a trapezoidal cross section, and an outer ring 112. The plurality of stainless steel wires 111 are evenly arranged on the inner wall of the outer ring 112 along the axial direction of the outer ring 112, and a filter groove is provided on the outer ring 112 corresponding to the gap between two adjacent stainless steel wires 111. Among them, the short side of the stainless steel wire 111 is fixed to the outer ring 112, and the long side of the stainless steel wire 111 is a free end face. The filtering accuracy of the filter column 11 is determined by the long side of the stainless steel wire 111. The minimum width of two adjacent stainless steel wires 111 is 0.15-1.00mm, that is, the filtering accuracy of the filter column 11 is 0.15-1.00mm. By replacing different filter columns 11, its filtering accuracy can be adjusted within the range of 0.15-1.00mm.

[0029] The filter column of the utility model adopts a structure in which a stainless steel wire with a trapezoidal cross section is fixed in an outer ring. The structure is strong and durable, and the filtering accuracy ranges from 0.15mm to 1.0mm. A filtering accuracy can be arbitrarily selected according to the impurities in the water, and the filter column can be replaced regularly according to the usage. Due to the use of multiple filter columns for filtering and single filter column backwashing, when the equipment automatically backwashes the filter residue, most of the filter columns are still working normally, ensuring the normal operation of the water supply system. The filter column has the function of being detachable, cleanable and replaceable, which can save a lot of manpower and material resources, reduce costs, increase filtering accuracy, improve water quality, and extend the service life of the equipment.

[0030] Specifically, the backwashing mechanism includes a driving assembly 12, a hollow shaft 13, and a sewage pipe 14. The driving assembly 12 includes a motor and a reducer, and the motor is connected to the reducer. The reducer is connected to the upper end of the hollow shaft 13 through a coupling, and the lower end of the hollow shaft 13 is connected to the upper filter plate 9 of the filtering mechanism through a bearing to realize the rotation of the hollow shaft 13. The lower end of the hollow shaft 13 is connected to the sewage pipe 7, and the inner diameter of the sewage pipe 7 can be greater than or equal to the inner diameter of the hollow shaft 13, so as to discharge the dirt in the hollow shaft 13 into the sewage pipe 7. The side wall of the hollow shaft 13 is connected to one end of one or more sewage pipes 14, and the other end of the sewage pipe 14 is connected to the filter column 11 of the filtering mechanism. For example, the filter columns 11 of the utility model are evenly arranged on two circumferences between the upper filter plate 9 and the lower filter plate 10, that is, the inner filter column 11 and the outer filter column 11; two sewage pipes 14 are set on the side wall of the hollow shaft 13. At this time, one sewage pipe 14 is connected to the inner filter column 11, and the other sewage pipe 14 is connected to the outer filter column 11, so that the two filter columns 11 on the inner and outer circles can be backwashed at the same time.

[0031] The magnetic box 4 is provided with a parallel arrangement of a single magnetized multi-pole magnetic system, and the magnetic induction intensity of the magnetic system in the magnetic box 4 is greater than 200 mT. Figure 3 and Figure 4 The magnetic system includes multiple rows of magnetic groups 41 arranged axially along the magnetic box 4, and each row of magnetic groups 41 is provided with multiple magnetic blocks along the axial and radial directions of the magnetic box 4. Wooden blocks 42 are provided at the ends of each row of magnetic groups 41 along the axial and radial directions of the magnetic box 4 to ensure that there is no magnetic leakage. The N pole and S pole of the magnetic groups of two adjacent rows are arranged opposite to each other. The magnetic blocks are made of NdFeB strong permanent magnetic material. The utility model is also provided with a water diversion plate 43 corresponding to the positions of the magnetic groups 41 and the wooden blocks 42 above the magnetic box 4. The cross-section of the water diversion plate 43 is triangular, which is used to make the water flow evenly when passing through the magnetic box 4. The magnetic box 4 of the utility model is circular, which can allow more water to flow through the center.

[0032] The utility model adopts high-performance NdFeB magnetic materials and advanced magnetic circuit design, and the magnetization field is uniform and powerful, and the magnetic induction intensity B reaches more than 200mT (JC / T3066-1997 stipulates that the maximum magnetic induction intensity B in the center is ≥160mT), so that various molecules and ions in the water can obtain considerable magnetic energy, destroying their scaling ability. When the water after the equipment magnetization leaves the water outlet and enters other circulation systems, it encounters the situation of temperature rise, and calcium, magnesium, iron and other ions become flocculent, flow with the water, and no longer deposit and adhere to the wall of the device, and no scale attached to other equipment pipelines is generated. The purpose of equipment and pipeline descaling is achieved, and the magnetic descaling device can work continuously, and the magnetic field intensity is ≥200mT.

[0033] The housing 1 is also provided with an observation port 5 for observing the internal conditions of the housing 1 and facilitating maintenance by the staff.

[0034] The working principle of the utility model is as follows: under normal working conditions, the water in all pipelines and the housing 1 maintains a certain pressure. When backwashing is required, the drain valve 8 is opened to reduce the pressure inside the housing 1, and the water in the filter cavity between the upper filter plate 9 and the lower filter plate 10 backwashes the filter column 11 and is discharged from the housing 1 through the drain pipe 7. Driven by the motor and the reducer, the sewage pipe 14 transfers from one filter column 11 to the next filter column 11 to backwash it until all the filter columns 11 complete one backwashing.

[0035] The utility model water quality stabilization purification device can realize the integration of descaling and filtration. The descaling part adopts a single magnetized multi-pole magnetic system to increase the magnetic induction intensity by 300%. The backwashing mechanism does not require auxiliary equipment, saving a lot of investment. Through computer simulation, different process designs are carried out for different media, flow rates, flow rates, and temperatures, so that the permanent magnetic material works at the maximum magnetic energy accumulation point, so that the "utilization number" of the magnetic field reaches the maximum value. Anti-corrosion, descaling, iron removal and water hardness monitoring are combined together to minimize the corrosion rate of equipment and pipeline walls, prevent the formation of scale, and soften the original scale, thereby achieving the purpose of descaling, scale prevention, sterilization and algae removal.
