DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] As Figures 1 to 5 Indicated, the utility model provides pressure balance device based on water purification equipment, including water purification pipeline 1, the inside fixed sleeve of water purification pipeline 1 top is connected with vertical pipe 2, the top fixed connection of vertical pipe 2 has pressure relief chamber 3, the inside fixed connection of vertical pipe 2 right side has first connecting pipe 4, the inside movable sleeve of first connecting pipe 4 has second connecting pipe 5, the other end of second connecting pipe 5 penetrates pressure relief chamber 3 and extends to the inside of pressure relief chamber 3 and fixed sleeve has cavity hose 6, cavity hose 6 is made of high density polyethylene, the top and bottom of second connecting pipe 5 are fixedly connected with No. 2 sealing plate 8 and No. 1 sealing plate 7 respectively, the outer surface of No. 1 sealing plate 7 and No. 2 sealing plate 8 is movably connected with the inside of pressure relief chamber 3.
[0023] When the water level inside the clean water pipeline 1 rises and floods the left end of the first connecting pipe 4, the continuously rising water level will press the air inside the first connecting pipe 4 and the second connecting pipe 5 into the inside of the cavity hose 6, so that the pressure inside the cavity hose 6 becomes larger, and the cavity hose 6 expands to block the top of the inner cavity of the vertical pipe 2. When the water level rises to the bottom of the cavity hose 6, the water pressure will make the first sealing plate 7 and the second sealing plate 8 and the second connecting pipe 5 move vertically upward under the limiting action of the pressure relief cavity 3 and the first connecting pipe 4 respectively, and the blocking effect on the top of the vertical pipe 2 is removed, so that the sewage in the clean water pipeline 1 can flow into the inner cavity of the pressure relief cavity 3.
[0024] The bottom of the second connecting pipe 5 is fixedly connected with a spring 9, and the bottom end of the spring 9 is fixedly connected with the outer surface of the pressure relief cavity 3.
[0025] Due to the design of the spring 9, the cavity hose 6 and the second connecting pipe 5 will not be lifted by the air pressure in the first connecting pipe 4 before the water level reaches the bottom of the cavity hose 6.
[0026] The inside of the top of the pressure relief cavity 3 is fixedly installed with a hydrophobic air-permeable filter screen 10, and the hydrophobic air-permeable filter screen 10 is made of polytetrafluoroethylene. The left and right sides of the inner cavity of the pressure relief cavity 3 are fixedly connected with triangular plates 11.
[0027] Such a design makes the air in the pressure relief cavity 3 pass through the hydrophobic air-permeable filter screen 10 and be discharged, and the water cannot overflow the device through the hydrophobic air-permeable filter screen 10.
[0028] The left side of the pressure relief cavity 3 is fixedly connected with a motor 12, and the other end of the output shaft of the motor 12 is fixedly sleeved with a rotating shaft 13.
[0029] When the motor 12 starts to operate, the rotating shaft 13 will rotate.
[0030] The other end of the rotating shaft 13 is fixedly sleeved with a rotating plate 14, and the left and right sides of the outer surface of the rotating plate 14 are movably connected with sleeve rods 15.
[0031] When the rotating shaft 13 rotates, the rotating plate 14 will start to rotate and push the sleeve rods 15 to move.
[0032] The outer side of the sleeve rod 15 is fixedly connected with a connecting rod 16, the other end of the connecting rod 16 penetrates through the pressure relief cavity 3 and extends into the inside of the pressure relief cavity 3 and is fixedly connected with a pushing plate 17, and the outer surface of the pushing plate 17 is movably connected with the inner surface of the pressure relief cavity 3.
[0033] When the sleeve rod 15 moves, the connecting rod 16 and the pushing plate 17 will move horizontally left and right under the limiting action of the pressure relief cavity 3.
[0034] There are two push plates 17, both of which are the same size and have smooth outer surfaces.
[0035] This design allows the push plate 17 to move more smoothly within the pressure relief chamber 3, while also reducing friction between the push plate 17 and the pressure relief chamber 3, thus improving the service life of the push plate 17.
[0036] Working principle and usage process of this utility model:
[0037] When the water level in the water purification pipe 1 rises and submerges the left end of the first connecting pipe 4, the continuously rising water level forces the air inside the first connecting pipe 4 and the second connecting pipe 5 into the cavity hose 6, increasing the pressure inside the cavity hose 6 and causing it to expand and block the top of the inner cavity of the vertical pipe 2. When the water level rises to the bottom of the cavity hose 6, the water pressure causes the cavity hose 6 to drive the first sealing plate 7, the second sealing plate 8, and the second connecting pipe 5 to overcome the elastic force of the spring 9 under the limiting action of the pressure relief chamber 3 and the first connecting pipe 4, thus releasing the sealing effect on the top of the inner cavity of the vertical pipe 2. This allows the sewage in the water purification pipe 1 to flow into the inner cavity of the pressure relief chamber 3, thereby relieving the pressure inside the water purification pipe 1 and achieving the function of balancing the internal pipe pressure of the water purification pipe 1.
[0038] When the water level inside the water purification pipe 1 drops, some sewage will remain at the bottom of the pressure relief chamber 3. At this time, starting the motor 12 will cause the rotating shaft 13 to drive the rotating plate 14 to rotate, and the rotating plate 14 will squeeze and push the sleeve rod 15. The two sleeve rods 15 will drive the two connecting rods 16 and the two push plates 17 to move horizontally towards each other under the limiting action of the vertical pipe 2. This will push the sewage remaining at the bottom of the pressure relief chamber 3 back into the inner cavity of the water purification pipe 1, preventing impurities inside the sewage from adhering to the inner cavity of the pressure relief chamber 3 and causing blockage inside the pressure relief chamber 3.
