Technical Field

[0001] The utility model relates to the technical field of siphon filters, in particular to an improved siphon filter. Background Art

[0002] A siphon filter is a filter that uses the siphon principle to replace the water inlet and outlet valves. In environments with high water resource utilization rates such as water plants and power plants, it is necessary to build siphon filters to treat water resources and ensure that water resources can be recycled.

[0003] The inventors discovered in their daily work that in the process of transforming the siphon filter, the structure of the existing siphon filter is relatively complex. In the actual construction process, the construction difficulty, cycle and transformation cost will increase, and it is difficult to ensure the quality after the transformation. When it is necessary to realize automatic operation of the filter, it is necessary to add vacuum tanks, generating devices, vacuum pumps and other equipment, which increases the complexity of the transformation. Utility Model Content

[0004] The utility model aims to solve the disadvantages of the prior art that when the automatic operation of the filter tank needs to be realized, a vacuum tank, a generating device, a vacuum pump and other equipment need to be added, resulting in increased complexity of the transformation, and an improved siphon filter tank is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an improved siphon filter, comprising a filter body and a filter plate, the filter plate is arranged on the inner wall of the filter body, the inner wall of the filter body is provided with a first filter groove, the inner wall of the filter body is provided with a second filter groove, the inner wall of the filter body is provided with a third filter groove, the inner wall of the filter body is provided with a clean water tank, the inner wall of the filter body is provided with a water outlet groove, the inner wall of the clean water tank is provided with a water outlet pipe, a long-handled filter head is provided on the filter plate, filter material is placed above the filter plate in the filter body, an air inlet pipe is installed on the inner wall of the clean water tank, and an air cushion layer is formed under the filter plate during aeration backwashing, and the pressure in the clean water tank is increased by the formed air cushion layer, thereby forcing the water level to drop so that the long air holes can be exposed.

[0006] Preferably, the long-handled filter head includes an embedded part, which is connected to the filter plate, a filter head screw is installed on the inner wall of the embedded part, a filter head cover is installed on the upper end of the embedded part, and long air holes are opened on the lower surface of the filter head screw. The speed of air flow can be reduced through the long air holes, thereby ensuring the production of an air cushion layer.

[0007] Preferably, the embedded parts penetrate the filter plate, the long air holes are connected to the interior of the clean water tank, and the filter head cover is located above the filter plate. The embedded parts allow construction personnel to assemble the long-handled filter head and ensure the accuracy of the long-handled filter head after installation.

[0008] Preferably, a siphon main body is installed on one side of the filter tank main body. A breaking pipe main body is installed on the surface of the siphon main body. A breaking valve is installed on the surface of the breaking pipe main body. A timing water tank is arranged inside the filter tank main body. An inlet channel is arranged on the inner wall of the filter tank main body. An air extraction pipe is installed on the surface of the siphon main body. An air extraction tee is installed on the surface of the air extraction pipe. An auxiliary siphon is installed on the inner wall of the air extraction tee.

[0010] Preferably, the breaking pipe main body is located inside the timing water tank, and the breaking pipe main body is communicated with the timing water tank.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] Air intake method: The air inlet pipe preferably penetrates through the filter plate from the top of the pool to the bottom of the pool. Because when manufacturing the filter plate, a hole can be reserved on a certain piece for the air inlet pipe to pass through, without damaging the pool wall or the bottom for air intake, so as to protect the structure of the pool.

[0013] The air inlet pipe goes down to the bottom of the pool and extends to the center of the pool. The air distribution main pipe enters the bottom of the pool through the holes reserved in the middle filter plate from the top of the pool. The air distribution branch pipes are arranged in a cross shape at the center of the bottom surface of the filter plate. The air distribution branch pipes are perforated pipes with the openings facing upwards, forming an "L" shape, and the openings should be aligned with the spaces between the central pipes of several long-stem filter heads, so that the air will not directly blow into the long-stem filter heads.

[0014] The air source adopts a Roots blower for direct air supply, and the air pressure of the gas entering the filter tank is controlled within 40 kPa.

[0015] The filter plate is installed firmly, and the joints are sealed with elastic sealing filler.

[0016] Due to raising the filter plate and installing long-stem filter heads, the filter material layer should be changed to a homogeneous filter material, and the thickness of the filter material layer is: 700 - 900 mm. Brief Description of the Drawings

The lower surface of the filter head screw 121 is provided with a long air hole 124, and the long air hole 124 can reduce the speed of the air flow, thereby ensuring the generation of the air cushion layer 13.

[0037] Specifically, the embedded part 122 penetrates the filter plate 2 , the long air hole 124 is connected with the interior of the clean water tank 6 , and the filter head cover 123 is located above the filter plate 2 .

[0038] In this embodiment, the embedded parts 122 allow construction workers to assemble the long-handled filter head 12 and ensure the accuracy of the long-handled filter head 12 after installation.

[0039] Specifically, an air cushion layer 13 is formed between the clean water tank 6 and the filter plate 2. The formed air cushion layer 13 increases the pressure in the clean water tank 6, thereby forcing the water level to drop so that the long air holes 124 can be exposed.

[0040] In this embodiment: a siphon body 14 is installed on one side of the filter body 1, a breaking pipe body 15 is installed on the surface of the siphon body 14, a breaking valve 151 is installed on the surface of the breaking pipe body 15, a timing water tank 16 is provided inside the filter body 1, an inlet channel 17 is provided on the inner wall of the filter body 1, an exhaust pipe 18 is installed on the surface of the siphon body 14, an exhaust tee 181 is installed on the surface of the exhaust tee 181, an auxiliary siphon 19 is installed on the inner wall of the exhaust tee 181, and a ground pipe 191 is installed on the inner wall of the auxiliary siphon 19.

[0041] In this embodiment, by installing the destruction valve 151 as a solenoid valve, it is convenient for the staff to control the operating state of the destruction tube.

[0042] Specifically, a forced operating valve 20 is installed on the surface of the destruction pipe body 15, a liquid level controller 21 is installed on the inner wall of the filter tank, a forced auxiliary valve 22 is installed on the surface of the exhaust pipe 18, and a fan 23 is installed at the input end of the intake pipe 11. The fan 23 can be used to inject air into the intake pipe 11 to achieve the air intake effect of the intake pipe 11.

[0043] Specifically, the destruction tube body 15 is located inside the timing water tank 16 , and the destruction tube body 15 is communicated with the timing water tank 16 .

[0044] Working principle: During normal filtration, water passes through the filter material 9, the filter head cover 123, enters the filter head screw 121, goes down to the filter plate 2, enters the clean water tank 6 and gathers in the water outlet area. During aeration backwashing, air quickly diffuses along the bottom of the filter plate 2 and gathers under the filter plate 2 to form an air cushion layer 13. The air cushion layer 13 forces the water level under the filter plate 2 to drop, and the long air holes 124 on the filter head screw 121 are exposed to the water surface. At this time, a large amount of air enters the filter head screw 121 and passes through the filter under the guidance of the filter head screw 121. The head cover 123 enters the filter material 9 for air washing. When water washing is to be carried out, the air supply to the bottom of the pool is stopped. The air washing is completed and the water washing begins. The backwash water enters from the bottom of the filter head screw 121 and passes through the filter head cover 123 to enter the filter material 9 for water washing. When automatic adjustment is performed, in the later stage of a filter process of the filter tank, when the water level in the filter tank rises to the set backwash liquid level, the filter tank can be backwashed by setting the water level. The first step is to open the destruction valve 151 on the siphon main body 14 to stop the filter tank body 1 from entering water. Start the blower 23 and open the air inlet valve to perform air scrubbing on the filter. After the air scrubbing is completed, open the forced auxiliary valve 22 on the siphon main body 14 to perform air-water backwashing on the filter main body 1. Then stop the Roots blower 23 and close the air inlet electric valve. The backwash system performs single water backwashing. When the flushing is completed, close the forced operating valve 20 and the forced auxiliary valve 22 on the siphon main body 14, open the destruction valve 151 connected to the siphon main body 14, and stop the backwashing of the filter main body 1. After the flushing stops, The water level in the filter tank body 1 gradually rises. When the water level submerges the lower end of the destruction tube body 15, the air inlet is sealed. Due to the action of the auxiliary siphon tube 19 and the air extraction tee 181, the air in the siphon tube body 14 is continuously extracted to form a siphon, thereby restoring the water inlet and allowing the filter tank body to enter the filtration stage. By arranging a long-handled filter head, a siphon tube body, a destruction tube body and an air inlet pipe, the flushing effect of the siphon filter is enhanced, the renovation cost of the siphon filter is saved, and the renovation efficiency and convenience of the siphon filter are improved.
