[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] In the figure: 1 processing box, 2 partition, 3 filtering area, 4 feeding area, 5 filter screen, 6 pressure plate, 7 baffle, 8 spring, 9 limit block, 10 positioning plate, 11 fixing plate, 12 cover plate. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 As shown, a sludge filtering device for mixed incineration sewage includes a treatment box 1, a vertical partition 2 is arranged in the treatment box, and the partition is arranged on the bottom wall of the treatment box. The partition divides the treatment box into a filtration area 3 and a material discharge area 4. Specifically, a filter screen 5 is arranged in the filtration area, and a fixed plate 11 is arranged on the partition, and the fixed plate is located in the filtration area. The fixed plate includes a horizontal part and an inclined part, and the horizontal part is lower than the inclined part. A pressure plate 6 is slidably connected to the side wall of the treatment box in the filtration area, and the pressure plate slides toward one side of the partition. A fixed notch is opened on the partition, and the fixed notch connects the filtration area and the material discharge area. The fixed notch faces the pressure plate, and a baffle 7 is arranged at the fixed notch, and the baffle is connected to the side wall of the treatment box in the material discharge area through a spring 8.

[0016] The upper part of the unloading area is slidably connected to a limiting block 9, which abuts against the baffle and the side wall of the processing box. On the one hand, the limiting block limits the baffle, so that the pressure plate cooperates with the baffle to squeeze the sludge and further filter the water; on the other hand, the limiting plate clamps the baffle to prevent it from resetting, so that the sludge can be unloaded to the unloading area.

[0017] Furthermore, a positioning plate 10 is arranged above the filter screen, the positioning plate is connected to the partition, the upper end surface of the positioning plate is flush with the lower end surface of the pressing plate, and the upper end surface of the pressing plate is flush with the lower end surface of the horizontal part. The front and rear ends of the pressing plate respectively abut against the front and rear side walls of the processing box.

[0018] Furthermore, a cover plate 12 is arranged at the upper end of the processing box body, a feed port is arranged on the cover plate, and discharge ports are arranged at the lower parts of the filtering area and the feeding area.

[0019] The working principle of the utility model is as follows: sludge wastewater enters from the feed inlet, is placed on the filter net, water is filtered down, and sludge remains on the filter net. The pressing plate works to squeeze part of the sludge to one side of the baffle. During the squeezing process, part of the sludge and water overflow from the upper end of the pressing plate. Then the limit block is removed, the baffle is compressed, and the limit block is used to clamp the baffle, so that the squeezed sludge falls into the discharge area and is then collected for mixed combustion treatment.

[0020] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
