DETAILED DESCRIPTION

[0028] like Figure 1 As shown, a sewage slag separation and filtering device includes a scraper assembly 50 and a filter box; the filter box includes a first side plate 10, a second side plate 20, a third side plate 30, a fourth side plate 40, a bottom plate 60 and a cover plate 70. The filter box is a rectangular parallelepiped or a cube.

[0029] The first side panel 10, the second side panel 20, the third side panel 30, the fourth side panel 40, the bottom panel 60, and the cover panel 70 are all made of lightweight, high-strength materials with waterproof and corrosion-resistant properties. The first side panel 10, the second side panel 20, the third side panel 30, the fourth side panel 40, the bottom panel 60, and the cover panel 70 form a filter space, in which a water level alarm 80 is provided. The cover panel 70 is rotatably connected relative to the second side panel 20, and the cover panel 70 is connected to the second side panel 20 by a hinge 71. The first side panel 10 is provided with a water inlet 11 and a locking pin 72. The first side panel 10 and the cover panel 70 are locked in a closed position by the locking pin 72. The second side panel 20 is provided with a water outlet 21.

[0030] like Figure 3 A filter plate 31 is disposed between the third side panel 30 and the fourth side panel 40. Both the third and fourth side panels 30 and 40 are provided with vertical slots 34, into which the filter plate 31 is inserted. A filter screen 32 is secured to the filter plate 31. A scraper assembly 50 is also disposed within the filter box, where the scraper assembly 50 is in contact with the filter screen 32 and is positioned between the water inlet 11 and the filter screen 32.

[0031] like Figure 2 As shown, the filter screen 32 has filter holes 33 of the same diameter, ranging from 6 mm to 10 mm. The specific pore size can also be determined based on the volume of impurities. The filter screen 32 is made of stainless steel. The filter screen 32 can also be made of an acid- and alkali-resistant material, such as PP. The diameters of the water inlet 11 and the water outlet 21 are both 110 mm, 70 mm, or 65 mm.

[0032] like Figure 4 and Figure 5 As shown, the scraper assembly 50 includes a handle 51, a scraper support frame 52, and a scraper 53. In one embodiment, the handle 51 is arranged perpendicularly to the scraper support frame 52. The scraper support frame 52 includes a first support frame and a second support frame. The first support frame is arranged perpendicularly to the handle 51, the handle 51 is located in the middle of the first support frame, and the second support frame is connected to both ends of the first support frame. The scraper 53 is installed on the second support frame. The scraper support frame 52 and the scraper 53 are stored in the base plate 60.

[0033] Furthermore, the filter screen 32 is arc-shaped, the second support frame is arc-shaped, and the scraper 53 is an arc-shaped silicone scraper.

[0034] Another embodiment, such as Figure 6 and Figure 7 As shown, the scraper assembly 50 includes a handle 51 and a scraper 53. The scraper 53 extends along the length of the handle 51 and is fixed to the handle 51. The handle 51 is received in the fourth side plate 40.

[0035] Furthermore, the filter screen 32 is arc-shaped, the handle 51 is perpendicular to the bottom plate 60 , and the scraper 53 is a silicone scraper, which is perpendicular to the bottom plate 60 .

[0036] Another embodiment, such as Figure 8 and Figure 9 As shown, the scraper assembly 50 includes a metal bracket 54, a spiral scraper 55, and a stepper motor 56. The spiral scraper 55 is fixed to the metal bracket 54, and the stepper motor 56 is set on the second side plate 20. The stepper motor 56 is connected to the metal bracket 54 through a transmission mechanism. The metal bracket 54 is connected to the cover plate 70.

[0037] Furthermore, the metal bracket 54 is located in the middle of the filter screen 32 .

[0038] Furthermore, a water level alarm is installed approximately two-thirds to one-quarter of the height of the tank. In this implementation, a float-type water level alarm can be used. When the water level in the filter device rises above a set point, an alarm sounds. This is applicable to industrial wastewater pretreatment applications where water volume fluctuates significantly.

[0039] The principle of this utility model is:

[0040] Industrial wastewater containing solid waste enters the device through the water inlet, passes through the filter 32, removes solid waste with larger particles in the wastewater, and the filtered wastewater flows out through the outlet 21 and flows through the pipeline to the industrial park sewage treatment plant for centralized treatment.

[0041] When the solid waste accumulated in the filter screen 32 reaches a certain amount, in the first and second embodiments, the filter residue is scraped off by manually operating the scraper assembly 50 in the filter box. In the third embodiment, the stepper motor 56 drives the spiral scraper 55 to automatically scrape off the filter residue.

[0042] In order to improve the efficiency of manual operation, a water level alarm 80 is set at about two-thirds of the height in the filter box; when the filter screen 32 is blocked or the instantaneous water inflow is too large, causing the water level in the device to rise to a certain level, the water level alarm 80 will automatically sound an alarm to remind manual intervention.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
