DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] The utility model proposes an aluminum alloy grid filter device for a deep bed, comprising a box body 1, a water inlet 2 is arranged on one side wall of the box body 1, a water outlet 3 is arranged on the other side wall, a sealing cover 4 is arranged on the upper end of the box body 1, and a plurality of aluminum alloy grids 5 are arranged in the box body 1;

[0021] The water inlet 2 is fixedly connected to a side wall of the box body 1, so that the liquid to be filtered can enter the box body 1 conveniently;

[0022] The water outlet 3 is fixedly connected to a side wall of the box body 1, so that the liquid in the box body 1 can flow out of the box body 1;

[0023] The sealing cover 4 can seal the box body 1 to prevent the liquid from overflowing from the box body 1;

[0024] A pair of vertical plates 6 is provided between each pair of aluminum alloy grids 5, a horizontal plate 7 is provided between the pair of vertical plates 6, a pair of fixed nets 8 is fixedly installed between the pair of vertical plates 6, and the lower end of the fixed net 8 is fixedly connected to the upper end surface of the horizontal plate 7;

[0025] A filter material 9 is filled between a pair of fixed nets 8;

[0026] The two ends of the horizontal plate 7 are respectively fixedly connected to the lower ends of the pair of vertical plates 6 close to each other, so that the pair of vertical plates 6 can be relatively fixed. At the same time, the two ends of the fixed net 8 are respectively fixedly connected to the end surfaces of the pair of vertical plates 6 close to each other, so that they can be kept fixed. The filter material 9 can filter the liquid entering the box body 1. At the same time, the aluminum alloy grid 5 can support the filter material 9 in the pair of fixed nets 8 to prevent the filter material 9 from damaging the fixed nets 8 due to weight reasons.

[0027] Specifically, the inner wall of the box body 1 is symmetrically formed with a limiting groove 10, and the outer wall of the aluminum alloy grid 5 is fixedly installed with a limiting block 11 that is slidably connected to the limiting groove 10;

[0028] Under the action of the limiting groove 10 and the limiting block 11 , it is convenient for the staff to take the aluminum alloy grid 5 out of the box body 1 , and it is convenient for the staff to clean the impurities attached to the aluminum alloy grid 5 .

[0029] Specifically, a plurality of receiving ports 12 are formed in the sealing cover 4, and a sealing door 13 for sealing the receiving ports 12 is hingedly connected to the upper end surface of the sealing cover 4;

[0030] The staff can open the collecting port 12 by flipping the sealing door 13, so as to take out the pair of vertical plates 6, the horizontal plate 7, the pair of fixed nets 8 and the filter material 9, and replace the filter material 9.

[0031] Specifically, a handle 14 is fixedly installed between the pair of vertical plates 6;

[0032] The handle 14 can facilitate the staff to collect the pair of vertical plates 6, the horizontal plate 7, the pair of fixed nets 8 and the filter material 9.

[0033] Specifically, a thread groove 15 is formed on the upper end surface of the box body 1, and a bolt 16 threadably connected to the thread groove 15 is provided on the sealing cover 4;

[0034] Under the action of the threaded groove 15 and the bolt 16, the sealing cover 4 can be relatively fixed to the box body 1, so that it can seal the box body 1, and it is convenient to connect or disassemble them.

[0035] Working principle: first, the staff adds the liquid to be filtered into the box body 1 through the water inlet 2. At this time, the filter material 9 in the box body 1 can filter the liquid in turn, and the filtered liquid can be discharged from the water outlet 3. At the same time, the staff flips the sealing door 13 to open the collecting port 12, and pulls the handle 14 to take out a pair of vertical plates 6, horizontal plates 7, a pair of fixed nets 8 and filter material 9, so as to facilitate the replacement of the filter material 9. When filtering the liquid, the filter materials 9 can be replaced one by one so that the filter material 9 can still filter the liquid, thereby improving the filtering efficiency. At the same time, when it is necessary to clean the interior of the box body 1, the staff rotates the bolt 16 to disengage one end of the bolt from the threaded groove 15, and removes the sealing cover 4 from the box body 1, so as to take out a pair of vertical plates 6, horizontal plates 7, a pair of fixed nets 8 and filter material 9, and pulls the aluminum alloy grid 5 to make the limit block 11 slide out of the limit groove 10 and take it out of the box body 1, so as to facilitate the cleaning of the inside of the box body 1, which brings convenience to people.
