DETAILED DESCRIPTION

[0018] In order to make the technical purpose, technical scheme and beneficial effects of the utility model clearer, the technical scheme of the utility model will be further explained below in combination with the drawings and specific embodiments.

[0019] The utility model provides a kind of quick filter brick type fiber filter material filter tank for water treatment, including filter tank 1, with the overflow cooperation of filter tank 1 overflow tank 5, water distribution air distribution system, wherein an embodiment is as follows: overflow tank 5 is set in the opposite sides of filter tank 1, and two overflow tanks 5 are communicated, overflow tank 5 is equipped with forward water inlet 11 and backwash water outlet 12, forward water inlet 11 and backwash water outlet 12 are respectively equipped with the valve of control respective opening and closing, filter tank 1 and overflow tank 5 share adjacent side wall, the shared side wall height of filter tank 1 and overflow tank 5 is lower than the remaining side wall of filter tank 1, lower than the remaining side wall of overflow tank 5, i.e. the shared side wall of filter tank 1 and overflow tank 5 is overflow port (or be called overflow passage) for filter tank and overflow tank overflow communication above, the length direction of filter tank is extended to the both ends of overflow port, ensure that water flow can be evenly distributed into along the entire length direction of filter tank 1 when entering filter tank 1, avoid the situation that local water flow is too large or too small, simultaneously, when the water level in overflow tank 5 exceeds certain height, excess water will overflow back to filter tank 1 through overflow port.

[0020] Filter tank 1 is provided with water distribution air distribution system, and the water distribution air distribution system includes filter brick 2, air distribution distributor 8 communicated with filter brick 2, water distribution distributor 9 communicated with filter brick 2, fan 10, air distribution distributor 8 is communicated with fan 10 by pipeline with butterfly valve installed thereon, water distribution distributor 9 is communicated with forward water outlet 11 and backwash water inlet 12 respectively opened in filter tank by three-way valve, filter brick 2 is set as S-shaped filter brick, filter brick 2 is set in filter tank 1, nanometer short fiber filter material layer 13 is laid in filter tank 1 and covers the top of water distribution air distribution system, overflow port of filter tank 1 is located above nanometer short fiber filter material layer 13, interception hole plate is arranged between overflow port and nanometer short fiber filter material layer 13 in filter tank, and the interception hole plate is fixed with filter tank 1. Before water enters filter tank 1, it is evenly distributed into overflow tank 5 on both sides of filter tank 1, and then enters water distribution air distribution system after being evenly overflowed to nanometer short fiber filter material layer 13 from overflow tank 5. Nanometer short fiber filter material layer 13 is prior art, which is formed by pressing the silk with plastic particles after nanometer short fiber filter material is injected into the machine.

[0021] The intercepting hole plate is arranged in the filter tank at a height of at least one time of the height of the nanometer short fiber filter material layer. Further, the intercepting hole plate is in a plate structure covering in the filter tank, and the water passing holes in a matrix structure are arranged on the plate structure.

[0022] The use method and advantages of the device are:

[0023] The normal filter tank 1 operation is that water enters the overflow tank 5 through the positive water inlet 7, is evenly distributed on the nanometer short fiber filter material layer 13 through the intercepting hole plate arranged on the overflow tank 5, enters the filter brick 2, and is discharged through the positive water outlet 11. The backwashing is that the butterfly valve of the positive water outlet 11, the butterfly valve of the positive water inlet 7 and the butterfly valve of the backwashing water outlet 11 are opened, the butterfly valve of the fan 10 pipeline is opened, gas enters the S-shaped filter brick 2 through the air distribution device 8, then the impurities in the nanometer short fiber filter material layer 13 are rubbed and washed, then the butterfly valve of the backwashing water inlet 12 is opened, the backwashing water enters the S-shaped filter brick 2 through the water distribution device 9, and the impurities in the nanometer short fiber filter material layer 13 are washed again. Finally, the butterfly valve of the fan 10 is closed, a large amount of backwashing water is entered, until the water quality in the tank body is clear, and the cleaning is completed. The butterfly valve of the backwashing water inlet is closed, the butterfly valve of the backwashing water outlet is closed, the butterfly valve of the water outlet 11 is opened, the butterfly valve of the positive water inlet 7 is opened, and the filtering stage is entered again.

[0024] Due to the porous structure of the filter brick, the nanometer short fiber filter material layer is in an expanded and suspended state by the gas and the water. The intercepting hole plate at the upper part of the filter tank reserves a backwashing space not less than the height of the nanometer short fiber filter material layer 13, ensures uniform distribution of the gas, and effectively avoids the nanometer short fiber filter material layer 13 from running.

[0025] Finally, it should be explained that the above-mentioned embodiments are only used for illustration but not for limiting the technical scheme of the device, any equivalent replacement, modification or partial replacement of the device without departing from the spirit and scope of the device should be covered in the protection scope of the device.
