Detailed Description

For the purposes of understanding, the specific structure and operation of the invention is set forth in the following description in connection with the accompanying drawings:

the concrete structure of the utility model is shown in figures 1-3, and the concrete structure of the invention is shown in figures 1-3, and comprises a filter box 10. If necessary, the filter box 10 may be provided with a corresponding stirring assembly 12 for stirring the sewage mixture in the inner cavity of the filter box 10, and the feed port 11 is configured to meet the corresponding feeding requirement. Meanwhile, a quadruple filtering structure as shown in fig. 1-2 is arranged in the filtering tank 10 to realize the requirements of layer-by-layer filtering and synchronous slag discharge.

Specifically, as shown in fig. 1 to 3, the quadruple filter structure includes a first filter plate 20, a second filter plate 32, a third filter plate 50 and a filter cloth 80, which are sequentially arranged from outside to inside, and the filter holes of the quadruple filter structure may be gradually tapered, or may be arranged as appropriate according to the field situation. When installed, the corresponding filtering structure forms a two-set type plane symmetrical layout as shown in fig. 1, so as to improve the operation efficiency and reliability.

The first filter plate 20 is disposed in a manner as shown in fig. 1, and is vertically installed in the filter tank 10, and vertically moved up and down by a lifting rod 70. The first filter plate 20 is provided at the bottom thereof with a first draw pin 41 as shown in fig. 2 to 3, thereby achieving both the function of separating the first filter plate 20 from the middle partition plate 31 and the limitation of the upward distance of the first filter plate 20. When the first filter plate 20 moves upward beyond the limit, the first filter plate 20 will drive the first pulling plug 41 to pull the middle partition plate 31 to tilt upward, and the middle partition plate 31 will drive the second filter plate 32 to move upward.

The second filter plate 32 is disposed between the middle partition plate 31 and the sidewall of the filter tank 10, and has an arch-type mesh shape so as to treat the primarily filtered sewage mixture in the largest area. The bottom end of the second filter plate 32 is provided with an inner flap 33 in an inward-turning manner. In fig. 2-3, the inward-turning plate 33 and the matching plate 34 form a hinged fit, so that when the second filter plate 32 moves upward, the second pulling plug 42 is pulled, and the inward-turning plate 33 is driven to move upward by means of the cap limiting function of the second pulling plug 42, as shown in fig. 3, so that the filter residue enters the residue discharge port through the filter residue below the matching plate 34, and finally falls into the residue discharge chamber f.

The first pulling bolt 41 and the second pulling bolt 42 are consistent in appearance and are both limiting column structures with bolt caps or screw caps arranged at two ends, the functions can be realized by arranging sieve plates with limiting steps at two ends in actual operation, and the sieve plates are only required to pass through corresponding filter residues. When each pulling plug is assembled at a corresponding part, the pulling plug is in sliding fit with a corresponding mounting hole forming hole shaft, namely, one end of the pulling plug is fixed while the other end of the pulling plug slides, or one end of the pulling plug is hinged while the other end of the pulling plug slides, so that when the first filter plate 20 or the second filter plate 32 moves upwards, a corresponding slag discharge path can be exposed after the pulling plug moves upwards for a specified distance, and the aim of sequentially removing filter residues is fulfilled. When the first pulling plug 41 and the second pulling plug 42 are installed, as shown in fig. 3, a raised edge may extend outward at the first filter plate 20 and a first installation hole may be provided at the raised edge, and the raised edge may also be arranged at the bottom of the second filter plate 32, so as to ensure the sealing performance of the corresponding cavity as much as possible; of course, a plurality of layers of sealing rings and the like can be arranged, and only the sealing effect is ensured to meet the basic requirement.

As for the slag discharging cavity f, as shown in fig. 1-2, it includes a blanking channel 61 and a slag discharging conveyer belt 62 arranged in sequence to meet the requirement of delivering the filter residue.

At the third filter plate 50, while it is ensured that the residue falls into the root, i.e. the bottom, the purpose of discharging the residue accumulated at this location can be achieved by means of an electrically or even manually operated valve 35. The filter cloth 80 is replaced and cleaned regularly, and because the liquid at the position is very pure and has few filter residues, the cleaning period can be prolonged properly to ensure the filtering efficiency. The third filter plate 50 is composed of a groove plate 51 and a plate-shaped filter element 52, so that the third filter plate can be cleaned and maintained at any time; a drainage plate 51a extends below the groove plate 51 to drain filter residues into the residue discharge cavity f.

To facilitate a further understanding of the invention, the actual workflow of the invention is described herein below in conjunction with FIGS. 1-3:

1) First, the sewage discharge motor is started, and the sewage mixture is introduced into the first filtering area a shown in fig. 1 from the feed port 11. Under the stirring action of the stirring assembly 12, large particles may settle at the bottom of the first filtering region a, and slide and accumulate at the bottom of the first filter plate 20 along with the slope structure of the middle partition plate 31. The particles of normal and fine sizes enter the second filtering area b from the filter holes of the first filter plate 20 and filter the foreign particles of normal size, which are collected at the bottom of the second filter plate 32 along with the inclined side walls of the filter tank 10, by the second filter plate 32. Then, the remaining fine particles enter the third filtering area c, i.e. the outer chamber, with the water, and the third filter plate 50 further filters the fine particles, and the water flow then enters the upper chamber d. Finally, the water flow in the upper chamber d passes through the final filter cloth 80 with fine filter holes, so that the water becomes relatively pure water and enters the lower chamber e for subsequent use.

2) When cleaning is needed, the lifting rod 70 above the middle is pulled to drive the first filter plates 20 at the two sides to move upwards. At this time, the first filter plate 20 is first gradually separated from the middle partition plate 31, so that the large-particle filter residues originally collected therein slide into the second filter region b and are collected with the impurity particles of general particle size. The lifting rod 70 is further lifted, the first filter plate 20 moves upward to the control limit of the first pulling plug 41, and the first pulling plug 41 starts to drive the elastic middle partition plate 31 to move upward as shown in fig. 2-3. The middle partition plate 31 moves upward together with the second filter plate 32 fixed thereto, and then pulls the inner flap 33 upward as shown in fig. 3, thereby exposing the slag discharge passage. The collected filter residues enter a slag discharge port through a slag discharge channel formed by the matching plate 34 and the side wall of the filter box 10, and finally fall into a slag discharge cavity f. The second pull stud 42 limits the maximum upward travel of the inner flap 33. The filter residue in the third filtering area c can be controlled by the valve 35 to fall into the lower slag discharge port because the filter residue has a relatively fine particle size, so to speak, the formed fine-particle filter mud.

After each filter residue falls into the slag discharge cavity f, the speed of the filter residue is reduced through the blanking channel 61, then the filter residue falls into the feeding belt of the slag discharge conveying belt 62, and finally the filter residue is conveyed away through the slag discharge conveying belt 62 to finish the discharging operation.
