[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a sand media clarification and filtration device, including a filter box 1, a support leg 6 installed on the filter box 1, a door 3 hinged to the filter box 1, a feed hopper 2 provided on the filter box 1, an opening and closing assembly 4 provided on the filter box 1, an anti-clogging assembly 5 provided inside the filter box 1, and a filter plate 7 installed inside the filter box 1, with filter holes 8 opened on the filter plate 7. Quartz sand is injected into the filter box 1 and filtered through the filter plate 7. The filtered quartz sand is discharged through a discharge device, and the remaining casting debris after filtration falls onto the filter plate 7. The door 3 can be opened by the opening and closing assembly 4 to remove the filtered and clarified quartz sand. The opening and closing is convenient and easy to remove. The anti-clogging assembly 5 can clean the debris located in the filter holes 8, avoiding the phenomenon of filter holes 8 being blocked and affecting the filtration efficiency, improving practicality, and eliminating the need for manual cleaning of each filter hole 8.

[0024] The anti-clogging component 5 includes two guide plates 51 and a mounting plate 56 installed inside the filter box 1. Two sliders 52 are slidably connected between the two guide plates 51. Two connecting plates 55 are rotatably connected to the bottom of each slider 52. A set of push rods 57 is installed at the bottom of the mounting plate 56. A bidirectional screw 53 is rotatably connected inside the filter box 1 and is threaded to the sliders 52. A servo motor 54 is installed at one end of the filter box 1. The output shaft of the servo motor 54 is connected to the bidirectional screw 53. All four connecting plates 55 are rotatably connected to the mounting plate 56. The servo motor 54 drives the bidirectional screw 53 to rotate, causing the sliders 52 to slide on the guide plates 51. This, in turn, causes the connecting plates 55 to rotate, causing the mounting plate 56 and push rods 57 to move downwards, so that the push rods 57 are engaged in the filter holes 8, thus ejecting and cleaning the debris inside the filter holes 8.

[0025] like Figure 3 As shown, in some embodiments, the top rod 57 is sized to match the filter hole 8; this facilitates cleaning.

[0026] like Figure 4 As shown, in some embodiments, the opening and closing assembly 4 includes a fixing block 41 installed at one end of the filter box 1. A fixing rod 40 is installed inside the fixing block 41. Two sliding plates 42 are slidably connected to the fixing rod 40. A locking plate 43 is installed at one end of each of the two sliding plates 42. Two mounting blocks 46 are installed at one end of the box door 3. A slot 47 is opened at the close end of each of the two mounting blocks 46. A spring 45 is installed between the two sliding plates 42. A handle 44 is installed at one end of each of the two sliding plates 42. When opening, the two handles 44 are squeezed relative to each other, causing the sliding plates 42 to slide on the fixing rod 40 and squeezing the spring 45, thereby causing the locking plate 43 to disengage from the slot 47, and then the box door 3 can be opened to take out the material.

[0027] like Figure 4As shown, in some embodiments, the size of the card plate 43 matches the card slot 47; this facilitates opening and closing.

[0028] like Figure 1 As shown, in some embodiments, the door 3 is provided with an observation window for easy observation.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
