[0026] Please see Figure 1-8 This utility model provides a technical solution: a multi-media filtration type environmentally friendly wastewater pretreatment device, including: a filter box 1 and a filter shell 2. The inner wall of the filter box 1 is provided with an installation groove 101 and an installation groove 2 102. One end of the filter shell 2 is installed on the inner wall of the installation groove 101, and the other end of the filter shell 2 is installed on the inner wall of the installation groove 2 102. A handle 3 is installed on the other end of the filter shell 2. A filter screen 4, a filter plate 1 6 and a filter plate 2 7 are installed inside the filter shell 2. A filter membrane 8 is installed at the bottom of the inner wall of the filter shell 2. A sealing plate 9 is installed on the surface of the installation groove 2 102 by bolts. A water inlet 10 is installed on the top of the filter box 1.

[0027] Specifically: When the device is first used, the bolt-fixed sealing plate 9 is removed to expose the handle 3 installed on one side of the filter housing 2. Then, by holding the handle 3 and pulling it outward, the filter housing 2 is removed from the inside of the filter box 1. This allows the filter screen 4, filter plate one 6, filter plate two 7 installed inside the filter housing 2, and the filter membrane 8 installed at the bottom of the inner wall of the filter housing 2 to be cleaned after use. This makes it easier to clean the internal cleaning components of the device after filtering impurities, making the device more complete.

[0028] In one embodiment, the filter housing 2 has a limiting block 201 on both sides, and the filter box 1 has a limiting groove 103 on both sides of the inner wall. The surface of the limiting block 201 is movably mounted on the inner wall of the limiting groove 103.

[0029] Specifically: The limiting blocks 201 on both sides of the filter housing 2 are movably installed on the inner wall of the limiting grooves 103 on both sides of the inner wall of the filter box 1, so that the filter housing 2 can be removed from the inside of the filter box 1 more smoothly and stably, making the device more perfect.

[0030] In one embodiment, the filter screen 4 is bolted to the top of the filter housing 2, and a baffle 5 is installed on the top of the filter screen 4. Two limiting blocks 601 are fixedly installed on both sides of the filter plate 6. Two limiting grooves 203 are opened on both sides of the inner wall of the filter housing 2. The surface of the limiting block 601 is movably installed on the inner wall of the limiting groove 203. Two limiting blocks 701 are fixedly installed on both sides of the filter plate 7. Two limiting grooves 202 are opened on the other two sides of the inner wall of the filter housing 2. The surface of the limiting block 701 is movably installed on the inner wall of the limiting groove 202.

[0031] Specifically: Filter screen 4 is bolted to the top of filter housing 2. Filter screen 4 filters larger impurities in the wastewater, leaving them on the top. A baffle 5 fixedly installed on the top of filter screen 4 prevents impurities from falling off when filter housing 2 is removed. Limiting blocks 601 fixedly installed on both sides of filter plate 6 are movably installed on the inner wall of limiting grooves 203 on both sides of the inner wall of filter housing 2, ensuring stable installation of filter plate 6 inside filter housing 2. Filter plate 6 is made of quartz sand and anthracite, forming a loose-on-top, tight-on-bottom filter layer structure to improve filtration efficiency and better remove fine particles and some organic matter from wastewater. Limiting blocks 701 fixedly installed on both sides of filter plate 7 are movably installed... The inner walls of the limiting grooves 202 on both sides of the inner wall of the filter housing 2 allow the filter plate 7 to be stably installed inside the filter housing 2. The filter plate 7 is made of polyester fiber, which has good chemical corrosion resistance and mechanical strength, and high filtration accuracy. It can remove small particles and colloidal substances in wastewater. The filter membrane 8 installed at the bottom of the inner wall of the filter housing 2 filters heavy metal ions and small molecule organic matter in the wastewater, so that the device can better filter the wastewater. By unscrewing the bolts used to fix the filter screen 4, the filter screen 4 can be removed, and the filter plate 6 and filter plate 7 inside the filter housing 2 can also be removed. Thus, the filter components inside the device are of the split type, which can be disassembled for cleaning, making cleaning more convenient and the device more complete.

[0032] In one embodiment, a hand-held block 602 is mounted on the top of filter plate 6, and a hand-held block 702 is mounted on the top of filter plate 7.

[0033] Specifically: By using the hand-held block 602 installed on the top of filter plate 6 and the hand-held block 702 installed on the top of filter plate 7, the filter plates 6 and 7 can be removed by hand using the hand-held blocks 602 and 702 respectively, making the removal of filter plates 6 and 7 more convenient and faster, and making the device more complete.

[0034] In one embodiment, a stop 901 is fixedly installed on one side of the sealing plate 9, and the other side of the stop 901 is attached to the other end of the filter shell 2.

[0035] Specifically: When the filter housing 2 is installed inside the filter box 1, the stop block 901 fixedly installed on one side of the sealing plate 9 will hold the filter housing 2 against the surface of the mounting groove 102 by bolts. This allows the filter housing 2 to be stably installed inside the filter box 1, making the device more complete.

[0036] In one embodiment, a water pump 11 is installed at the bottom of the filter box 1, and a water pipe 12 is installed at the output end of the water pump 11.

[0037] Specifically: During use, the water pump 11 is started to discharge the filtered water inside the device through the water pipe 12 installed at the output end of the water pump 11, making the device more complete.

[0038] Working Principle: When the device is first put into use, wastewater enters the interior of filter box 1 through the inlet 10 installed at the top of filter box 1. Larger impurities in the wastewater are filtered through the filter screen 4 installed at the top of filter shell 2, leaving the impurities on the top of the screen 4. A baffle 5 fixedly installed at the top of the screen 4 prevents impurities from falling off when filter shell 2 is removed. Filter plate 6 is made of quartz sand and anthracite, forming a loose-on-top, tight-on-bottom filter layer structure to improve filtration efficiency and better remove fine particles and some organic matter from the wastewater. Filter plate 7 is made of polyester fiber, which has good chemical corrosion resistance and mechanical strength, and high filtration accuracy, removing tiny particles and colloidal substances from the wastewater. The filter membrane 8 installed at the bottom of the inner wall of filter shell 2 filters heavy metal ions and small molecule organic matter from the wastewater, thus enabling the device to better filter and treat wastewater. Then, by removing the bolts securing the sealing plate 9, the handle 3 installed on one side of the filter housing 2 is exposed. Then, by pulling the handle 3 outwards, the filter housing 2 is removed from the inside of the filter box 1. This allows the filter screen 4, filter plate one 6, filter plate two 7, and the filter membrane 8 installed at the bottom of the inner wall of the filter housing 2 to be cleaned after use. This allows the internal cleaning components to be removed and cleaned after filtering impurities, making the device more complete. By unscrewing the bolts securing the filter screen 4, the filter screen 4 is removed from the top of the filter housing 2. Then, by pulling the first hand block 602 upwards, the filter plate one 6 is removed from the inner wall of the filter housing 2, and by pulling the second hand block 702 upwards, the filter plate two 7 is removed from the inner wall of the filter housing 2. This makes the internal filter components of the device modular, allowing them to be disassembled for individual cleaning, making cleaning more convenient and the device more complete.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
