[0047] Filter box 210;

[0048] Filter screen 211; Filter screen 211 is installed inside the filter box and is used to filter solid impurities such as slag from the accumulated water; Filter screen 211 divides the filter box into an upper chamber and a lower chamber, and the filter box 210 is provided with an outlet 213 that communicates with the lower chamber. In this way, the accumulated water pumped into the upper chamber is filtered by the filter screen to remove solid impurities, and the filtered water enters the lower chamber and is discharged through the outlet of the lower chamber.

[0049] Cleaning unit; The cleaning unit is used to clean the slag on the filter screen.

[0050] Collection box 220; There are two collection boxes 220, which are respectively set on both sides of the filter box and are used to collect the slag cleaned from the filter screen.

[0051] The pumped water is filtered and discharged using a filtration device. The filtration device is equipped with a cleaning unit to clean the slag on the filter screen, preventing clogging during filtration. Furthermore, a collection box is installed on the filter box to collect the cleaned slag, preventing it from being left untreated and clogging the filter screen again. At the same time, the filter box increases the space available for slag in the collection box, reducing the frequency of downtime for cleaning and making the filtration device more practical.

[0052] Reference Figure 3 and Figure 4 In some embodiments, a collection frame 221 is provided inside the collection box 220. The opening of the collection frame 221 is located at the same level as or below the filter screen, so that the slag on the filter screen can be cleaned into the filter frame. A filter hole 222 is provided on the collection frame 221, and the water filtered out by the collection frame 221 can flow into the lower chamber.

[0053] A filter frame is installed inside the collection box to collect slag in a centralized manner while filtering out water from the slag, facilitating subsequent processing of the slag at the mining site.

[0054] like Figure 3 As shown, in some embodiments, a cleaning port 223 is provided on the collection box 220, and the size of the cleaning port 223 matches the size of the collection frame, so that the collection frame can be installed into the collection box through the cleaning port.

[0055] By setting up a cleaning port, the collection frame can be easily disassembled and assembled inside the collection box, thus facilitating the cleaning of slag inside the collection frame, reducing the time required to clean the collection frame, and improving work efficiency.

[0056] In some embodiments, the collection frame 221 is fixedly installed into the collection box 220 by a plurality of locking tabs 224; see reference Figure 3 The filter box 210 contains a support frame 212. One side of the collection frame 221 abuts against the support frame 212, and the other side of the collection frame 221 is supported on the cleaning port 223. A locking plate securely fixes the collection frame to the collection box. The locking plate 224 can be fixed to the collection box at both ends by locking screws 225, thus securing the collection frame. During cleaning, the collection frame can be removed simply by unscrewing the locking screws.

[0057] like Figure 3 As described above, by setting a support frame, the filter screen 211 can be placed on the support frame 212, which facilitates the installation of the filter screen. An insertion slot can be provided on the support frame, into which the filter screen is inserted.

[0058] In some embodiments, a maintenance port 214 is provided on the filter box 210 at a position corresponding to the filter screen. The size of the maintenance port 214 matches the size of the filter screen, and the filter screen can be disassembled and assembled through the maintenance port.

[0059] A sealing plate 215 is provided on the inspection port 214, and the sealing plate 215 is fixedly connected to the filter box 210 by multiple clamping plates 216.

[0060] The filter screen can be easily replaced by providing an inspection port. The clamping plate 216 is fixedly connected to the filter box at both ends by clamping screws 218.

[0061] In some embodiments, the cleaning unit includes:

[0062] Cleaning brush 230 is positioned above filter screen 211;

[0063] The drive mechanism can drive the cleaning brush to reciprocate in the direction of the two filter boxes; when the cleaning brush reciprocates in the direction of the filter boxes, it can clean the slag on the filter screen into the two filter boxes.

[0064] In some embodiments, refer to Figure 1 The drive mechanism includes:

[0065] Motor 231;

[0066] The lead screw 232 is rotatably connected to the filter box and connected to the motor at one end;

[0067] Guide rod 233 is arranged side by side with the lead screw;

[0068] The slider 234 is connected to the lead screw drive and is slidably connected to the guide rod. One end of the slider 234 extends into the filter box through the window 217 provided on the filter box and is connected to the cleaning brush.

[0069] Two guide rods can be provided to prevent the slider from rotating and to guide the slider.

[0070] When the filter screen needs to be cleaned, the motor drives the lead screw to rotate in the forward and reverse directions. When the lead screw rotates, it drives the slider to move back and forth along the direction of the lead screw, thereby driving the cleaning brush to move back and forth to clean the filter screen.

[0071] The forward and reverse rotation control of the motor can be achieved through a program, or by setting limit switches at both ends of the lead screw. When the slider moves to contact the limit switch, the motor is controlled to rotate in the opposite direction.

[0072] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0073] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted.
