DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to solve the problem that the existing laminated filter unit and drain valve are made of plastic material, which has low pressure resistance and cannot be used in some industrial occasions due to high system pressure, please refer to Figure 1-Figure 4 , this embodiment provides the following technical solutions:

[0028] A high pressure resistant laminated filter, comprising:

[0029] A water outlet pipe 1 is used to discharge the filtered water to be treated;

[0030] A water inlet pipe 5, used for entering the water source to be treated;

[0031] The laminated filter unit 3 is used to filter the water source to be treated;

[0032] Three-way diaphragm drain valve 4, used to discharge flushing sewage;

[0033] The four-way pipe 11 is used to connect the laminated filter unit 3 so that the laminated filter can filter the water source to be treated multiple times.

[0034] In this embodiment, the water inlet pipe 5 is connected to the water inlet of the laminated filter unit 3, the water outlet pipe 1 is connected to the water outlet of the laminated filter unit 3, and a three-way diaphragm drain valve 4 is provided at the connection between the water inlet pipe 5 and the laminated filter unit 3.

[0035] It should be noted that the laminated filter adopts the method of water inlet through the upper pipe, water outlet through the bottom pipe and sewage discharge through the middle pipe. It can be used for sewage treatment, filtering impurities in the water body to achieve the purpose of water purification, and can meet process needs or emission requirements.

[0036] In this embodiment, a pressure gauge 6 is provided at one end of the water inlet pipe 5 , an exhaust valve 8 is provided at the other end of the water inlet pipe 5 , and a controller 7 is provided at the middle end of the water inlet pipe 5 .

[0037] It should be noted that the water source to be treated enters the laminated filter through the water inlet pipe 5. The gas in the water inlet pipe 5 will be compressed and discharged through the exhaust valve 8. At this time, the three-way diaphragm drain valve 4 is in a straight-through state. The water flows through and enters the laminated filter unit 3. After filtration, it enters the water outlet pipe 1 and enters the next water use unit.

[0038] In this embodiment, the three-way diaphragm drain valve 4 is also connected to a drain pipe 9 .

[0039] It should be noted that when the pressure difference reaches the setting value of the pressure difference switch built into the controller 7, or the filtration cycle reaches the setting value of the time switch built into the controller 7, the laminated filter automatically enters the backwash state, and the three-way diaphragm drain valve 4 is changed from the original straight-through direction to the angle-through direction, and the interior of the laminated filter unit 3 is connected to the drain pipe 9. Due to the water pressure in the outlet pipe 1, the clean water filtered in the outlet pipe 1 flows in reverse through the laminates in the laminated filter unit 3, and is discharged from the drain pipe 9 through the three-way diaphragm drain valve 4, thereby realizing the flushing function of the laminated filter unit 3.

[0040] Specifically, a three-way diaphragm drain valve 4 is used, and hydraulic pressure is used as a power to switch the passage of the three-way diaphragm drain valve 4 to achieve the purpose of cleaning the laminated filter unit 3.

[0041] In this embodiment, a Y-shaped filter 10 is provided on the water inlet pipe 5 .

[0042] It should be noted that the three-way diaphragm drain valve 4 switches the water flow direction from the original straight-through to the angle-through, which is achieved by the electromagnetic valve carried. The electromagnetic valve is a relatively precise instrument. In order to extend its service life, the water source entering the electromagnetic valve is filtered through a Y-type filter 10, which can reduce the wear of the electromagnetic valve core by impurities, thereby extending the service life of the electromagnetic valve.

[0043] In this embodiment, the laminated filter units 3 are interconnected by a four-way pipe 11 , and the laminated filter units 3 include a laminated filter element 31 and a unit housing 32 . The outer wall of the unit housing 32 is provided with a Vicar ring 2 , and the inner side of the unit housing 32 is provided with a laminated filter element 31 .

[0044] It should be noted that the single laminated filter units 3 are combined together through the four-way pipe 11, which can double the filtration flow and perform backwashing at the same time. The unit housing 32 is made of stainless steel and processed with seamless pipes to increase the pressure resistance.

[0045] Specifically, by adopting a modular assembly method, the order and position of the pipelines can be changed at will.

[0046] It should be noted that, according to the amount of water, the laminated filter can be selected to be composed of multiple laminated filter units 3. The laminated filter unit 3 is provided with a unique laminated filter element 31, which is composed of a group of plastic discs with grooves in different directions on both sides. The groove edges on the adjacent surfaces form a large number of intersections, which constitute a large number of cavities and irregular passages. These passages are continuously reduced from the outside to the inside. During filtration, these passages cause turbulence of water, and finally the impurities in the water are intercepted at various intersections to achieve the purpose of water purification; by configuring a unique three-way diaphragm The drain valve 4 can realize the backwashing of multiple laminated filter units 3 one by one in the normal system operation, and is fully automatically program-controlled, with the advantages of small backwashing water consumption, convenient equipment installation, and easy operation. The laminated filter has a large flow rate and does not require maintenance. It can be used in food, textile, metallurgy, plastics, medicine, building materials, papermaking, HVAC systems of industrial and commercial buildings, irrigation, wastewater treatment, sewage regeneration, municipal water supply, water plants, large power plants, chemical companies, and emergency filtration. The filtration level is based on the water quality requirements of the subsequent water use system or equipment.

[0047] In this embodiment, the cross-way pipe 11 is provided with a first filter unit connection port 111 and a second filter unit connection port 112 opposite to each other, and the cross-way pipe 11 is also provided with a unit water inlet 113 and a unit water outlet 114 opposite to each other.

[0048] It should be noted that the first laminated filter unit 3 and the second laminated filter unit 3 are respectively fixed on the first filter unit connection port 111 and the second filter unit connection port 112 to form a large filter unit. Under normal filtering conditions, the water source to be filtered enters the filter unit through the unit water inlet 113 for filtering, and water is discharged from the unit water outlet 114. When the unit is in the backwashing state, the three-way diaphragm drain valve 4 cuts off the water inlet of the water inlet pipe 5, and the water collected in the outlet pipe 1 after filtering by other filter units enters the first laminated filter unit 3 and the second laminated filter unit 3 through the unit water outlet 114 to backwash the laminates inside, and then the sewage after backwashing passes through the unit water inlet 113, and then enters the drain pipe 9 through the three-way diaphragm drain valve 4 for discharge.

[0049] Working principle: the water source to be treated enters the laminated filter through the water inlet pipe 5, and the gas in the water inlet pipe 5 will be compressed and discharged through the exhaust valve 8. At this time, the three-way diaphragm drain valve 4 is in a straight-through state, and the water flows through and enters the laminated filter unit 3, and enters the outlet pipe 1 after filtration, and enters the next water use unit; when the pressure difference reaches the set value of the pressure difference switch built into the controller 7, or the filtration cycle reaches the set value of the time switch built into the controller 7, the laminated filter automatically enters the backwashing state, and the three-way diaphragm drain valve 4 is changed from the original straight-through direction to the angle-through direction, and the inside of the laminated filter unit 3 is connected with the drain pipe 9. Due to the water pressure in the outlet pipe 1, the clean water filtered in the outlet pipe 1 flows in reverse through the laminates in the laminated filter unit 3, and is discharged from the drain pipe 9 through the three-way diaphragm drain valve 4, thereby realizing the flushing function of the laminated filter unit 3.
