Detailed Description
According to the above structural features of the present application, the embodiments of the present application will be further described:
Referring to fig. 1-2, a pre-filter device for treating landfill leachate comprises a drainage component for controlling the flow direction of liquid, a filter component 2 arranged in the drainage component for filtering solid impurities, and an annular sealing component fixedly connected with the filter component 2 and arranged between the drainage component and the filter component 2, wherein the sealing component is preferably a sealing ring 3. The drainage assembly comprises a shell 1, a liquid inlet 11 and a liquid outlet 12 which are mutually communicated, wherein the shell 1, the liquid inlet 11 and the liquid outlet 12 are arranged in a T-shaped mode. The sealing assembly acts as a barrier for preventing percolate from flowing through the gap between the drainage assembly and the filter assembly 2 directly into the liquid outlet 12. When the landfill leachate flows through the filter assembly 2, a large volume of garbage is reserved in the filter assembly 2, so that the post-treatment equipment of the landfill leachate is prevented from being blocked by the large volume of garbage.
Referring to fig. 1, the drainage assembly further comprises a top cover 13 arranged at the top end of the shell 1, wherein the top cover 13 is detachably connected with the shell 1 through an eye bolt 14; the outer surface of the top cover 13 is fixedly provided with a second handle 131 for grasping during disassembly.
Referring to fig. 1-3, the filter assembly 2 includes a first handle 22 and a filter cartridge 21 having a filter mesh-like (mesh diameter including, but not limited to, 5mm, 6mm, 8mm, but more than 2 mm) cylindrical structure with a top surface inclined, the first handle 22 being disposed at the top end of the filter cartridge 21 and fixedly coupled thereto. The first handle 22 facilitates grasping by equipment maintenance personnel to remove the filter assembly 2, and thereafter performing a cleaning operation of the filter assembly 2. The side walls of the cartridge 21 can cover the cross-section of the outlet 12 to ensure that the percolate flows preferentially through the cartridge 21 and then into the outlet 12. The drainage assembly further comprises a top cover 13 arranged at the top end of the shell 1, and the top cover 13 is detachably connected with the shell 1 through an eye bolt 14; the outer surface of the top cover 13 is fixedly provided with a second handle 131 for grasping during disassembly. The bottom of the shell 1 is provided with a drain outlet 15, and the liquid inlet 11, the liquid outlet 12 and the drain outlet 15 are all connected with a pipeline provided with a flange plate. The device maintainer can remove the eye bolts 14, open the top cover 13, take out the filter assembly 2 for cleaning (for example, cleaning the scale adhered to the mesh position of the filter cartridge 21), or further clean the inner walls of the shell 1, the liquid inlet 11 and the liquid outlet 12. The bottom end of the shell 1 is provided with a drain outlet 15, and the drain outlet 15 is kept in a normally closed state when the garbage leachate is filtered by the utility model. When equipment maintenance personnel wash the inner wall of the drainage assembly, the sewage outlet 15 is opened, so that sewage can be discharged; for example, scale removed from the inner wall is deposited in a chip shape on the bottom, and the scale is hard to be extracted by using a siphon pipe because of high density, so that the scale is conveniently flushed and discharged by using the drain 15 through cleaning liquid (such as water).
Referring to fig. 2, the filter cartridge 21 of the filter assembly 2 has at least a portion of its side wall that does not completely cover the cross section of the inlet 11. On the one hand, in the normal state, the diameter of the liquid inlet 11 is smaller than that of the shell 1, so that the shell 1 has larger volume than the liquid inlet 11/liquid inlet pipeline, the shell 1 is used for containing filtered solid impurities, the use effect is better, and the solid impurities stacked by the liquid inlet 11/liquid inlet pipeline have a higher probability of directly causing pipeline blockage.
Referring to fig. 4 to 5, the filter cartridge 21 is provided with an openable bottom plate 211, one end of the bottom plate 211 is hinged to the filter cartridge 21, the other end is provided with a snap-fit female buckle 212, and the bottom end of the inner wall of the filter cartridge 21 is provided with a snap-fit male buckle. The bottom plate 211 is rectangular, and the clamping female buckle 212 is arranged at the position of the top angle of the rectangle to avoid garbage accumulation. The clamping male buckle and the clamping female buckle 212 are mutually clamped in the closed state of the bottom plate 211; the top end of the clamping female buckle 212 extends upwards to form an extension part 213 which is convenient for a worker to grasp, and the extension part 213 is provided with a through hole for hooking. When the enterprise equipment is overhauled, the sewage outlet 15 is opened to drain residual sewage; then the top cover 13 is opened, the bottom plate 211 is pushed open, the inner wall of the filter cartridge 21 is cleaned by using a tool (such as a high-pressure water gun for flushing), and the collected garbage is discharged through the drain 15 along the inclined bottom plate 211; the operator then grasps the extension 213 or uses a tool (e.g., a drag hook) to hook the through-hole in the extension 213, closing the bottom plate 211. The scheme realizes the removal of solid impurities under the condition of the non-detachable filter cartridge 21, and avoids the abrasion between the outer edge of the annular sealing assembly and the inner wall of the shell 1 in the disassembly and assembly process.
