Abstract
Description
Technical Field
[0001] This utility model relates to the field of domestic wastewater treatment technology, and in particular to a solid impurity filtration device for domestic wastewater. Background Art
[0002] Domestic wastewater typically refers to wastewater generated in daily life, mainly from the use of households, businesses, and public facilities. Solid impurities in it, such as food scraps, grease, and dirt, can affect water quality and damage subsequent treatment equipment. Therefore, a solid impurity filtration device for domestic wastewater is needed to filter out most of the solid impurities in the wastewater to facilitate subsequent water treatment.
[0003] Normally, the device is first connected to the outlet of the wastewater pipe so that the wastewater can flow into the device. The multi-stage filter plates inside the device filter out most of the solid impurities in the wastewater. The filtered wastewater then flows to the next step of water treatment. After a period of use, the filter plates inside the device need to be removed to prevent the sieve holes on the filter plates from becoming completely blocked, which would lead to wastewater accumulation.
[0004] Considering that cleaning the filter plate requires disassembling the device, removing the filter plate, manually rinsing it with a large amount of water to clear the clogged sieve holes, or pulling the filter plate out from the side of the device and replacing it directly, not only is disassembling the device and cleaning the filter plate time-consuming, but also, during the cleaning process, solid impurities on the filter plate can easily pollute the environment due to the water flow. Therefore, a solid impurity filtration device for domestic wastewater is proposed to solve the above problems. Summary of the Invention

This process is not only time-consuming, but may also cause environmental pollution because impurities on the filter plate may be washed away and diffused by the water flow when rinsing the filter plate.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1 , Figure 3 , Figure 5This utility model provides an embodiment of a solid impurity filtration device for domestic wastewater, comprising a housing 1. A drain frame 3 is fixedly connected to the left side of the outer surface of the housing 1, providing fixed support for the drain frame 3. A drain plate 7 is elastically connected to the bottom end of the inner surface of the drain frame 3 via a spring 11, allowing the drain plate 7 to maintain an upward movement without external force. A filter plate 10 is slidably connected to the top end of the inner surface of the drain frame 3, allowing the filter plate 10 to move laterally along the top end of the inner surface of the drain frame 3. A drain column is fixedly connected to the top end of the outer surface of the drain plate 7, allowing the drain plate 7 to move vertically and drive the drain column to move together. The top end of the outer surface of the drain column is inserted into the inner surface of the filter plate 10, allowing the drain column to push out solid impurities in the sieve holes of the filter plate 10 when it is inserted into the filter plate 10. A pressing block 13 is fixedly connected to the left side of the bottom outer surface of the filter plate 10, allowing the filter plate 10 to move laterally. The filter plate 7 has a groove 12 on the right side of its outer surface. The bottom of the outer surface of the extrusion block 13 is slidably connected to the inner surface of the groove 12. When the filter plate 10 moves the extrusion block 13 laterally, the extrusion block 13 first contacts the groove 12, and the inclined surface of the extrusion block 13 presses against the inclined surface of the groove 12, causing the filter plate 7 to move downwards. The filter plate 10 can then move directly above the filter plate 7. The left side of the outer surface of the front end of the filter plate 7 has a slot 14, which allows the extrusion block 13 to engage with the left side of the inner surface of the filter plate 7. The inner surface of the slot 14 engages with the outer surface of the extrusion block 13. When the extrusion block 13 engages with the slot 14, the filter plate 7 moves upwards due to the elastic force of the spring 11 and engages with the filter plate 10. The front end of the outer surface of the filter plate 10 is provided with a positioning component, which fixes the filter plate 10 in a designated position when it moves to a designated position.
[0035] Reference Figure 4 - Figure 5 , Figure 7The positioning component includes a handle B5 and a wedge block 16. The rear end of the outer surface of the handle B5 is fixedly connected to the front end of the outer surface of the filter plate 10, so that when the handle B5 is pulled, the filter plate 10 can move laterally. The outer surface of the handle B5 is slidably connected to the front end of the inner surface of the unblocking frame 3 and the front end of the inner surface of the outer shell 1, so that the handle B5 can move laterally along the front end of the inner surface of the unblocking frame 3 and the front end of the inner surface of the outer shell 1. The outer surface of the wedge block 16 is slidably connected to the front end of the outer surface of the outer shell 1, so that the wedge block 16 can move vertically along the front end of the outer surface of the outer shell 1. The bottom end of the outer surface of the wedge block 16 is engaged with the inner surface of the handle B5, so that when the handle B5 moves to the right, the wedge block 16 can move upward due to the pressure on the inclined surface at the bottom end of the wedge block 16. When the handle B5 moves to the finger... When in a fixed position, the inclined block 16 will move downwards due to gravity and engage with the inner surface of the handle B5, so that the handle B5 drives the filter plate 10 to be fixed in the designated position. The outer surface of the unblocking plate 7 is slidably connected to the inner surface of the unblocking frame 3, so that the unblocking plate 7 can move vertically along the inner surface of the unblocking frame 3. The front end of the outer surface of the unblocking plate 7 is fixedly connected to the handle C6, so that when the handle C6 is pulled, the unblocking plate 7 can move vertically. The outer surface of the handle C6 is slidably connected to the front end of the inner surface of the unblocking frame 3, so that the handle C6 can move vertically along the front end of the inner surface of the unblocking frame 3, and the handle C6 can only move vertically a certain distance. So that when the unblocking plate 7 moves vertically under the action of the spring 11, it can only rise to the designated position due to the restriction of the handle C6.
[0036] Reference Figure 3 - Figure 4 A scraper 9 is slidably connected to the top of the inner surface of the unclogging frame 3, allowing the scraper 9 to move laterally along the top of the inner surface of the unclogging frame 3. A handle A4 is fixedly connected to the left side of the outer surface of the scraper 9, allowing the scraper 9 to move laterally when the handle A4 is pulled. The outer surface of the handle A4 is slidably connected to the left side of the inner surface of the top of the unclogging frame 3, allowing the handle A4 to move laterally along the left side of the inner surface of the top of the unclogging frame 3. The bottom end of the outer surface of the scraper 9 is slidably connected to the top end of the outer surface of the filter plate 10, allowing the scraper 9 to scrape the top end of the outer surface of the filter plate 10 when it moves laterally. One end of the spring 11 is fixedly connected to the bottom end of the inner surface of the unclogging frame 3, and the other end of the spring 11 is fixedly connected to the bottom end of the outer surface of the unclogging plate 7, allowing the unclogging plate 7 to move upward due to the elastic force of the spring 11 when the squeezing block 13 stops squeezing the top end of the outer surface of the unclogging plate 7.
[0037] Reference Figure 2 - Figure 3 , Figure 6A pin 15 is slidably connected to the left side of the top outer surface of the unclogging frame 3, allowing the pin 15 to move vertically along the left side of the outer surface of the unclogging frame 3. The bottom end of the outer surface of the pin 15 engages with the inner surface of the handle A4, allowing the handle A4 to engage with the pin 15 and thus fix the scraper 9 in a designated position. A wastewater pipe 2 is fixedly connected to the top of the outer surface of the outer casing 1, allowing wastewater to flow into the interior of the outer casing 1 along the wastewater pipe 2. The outer surface of the filter plate 10 is slidably connected to the inner surface of the outer casing 1, allowing the filter plate 10 to direct the flow into the interior of the outer casing 1 when it moves inside the outer casing 1. The wastewater inside the outer shell 1 is filtered. The rear end of the outer surface of the unblocking frame 3 is fixedly connected to the collection pipe 8, so that the solid impurities scraped by the scraper 9 can enter the collection pipe 8 for unified collection and treatment. There are two sets of collection pipes 8 and unblocking frame 3, so that the two sets of collection pipes 8 and unblocking frame 3 can clean and unblock the two sets of filter plates 10. The bottom end of the outer surface of one set of collection pipes 8 is fixedly connected to the top end of the outer surface of the other set of collection pipes 8, so that the two sets of collection pipes 8 can collect the solid impurities collected on the two sets of unblocking frames 3 in a unified manner.
[0038] Working principle: When using the device, first stop the wastewater input, then move the inclined block 16 upwards to release the handle B5 from its fixation. Then pull the handle B5 to the left, causing the filter plate 10 to move from the inside of the outer casing 1 to the inside of the unblocking frame 3. When the filter plate 10 moves to the left, the pressing block 13 fixed at its bottom will first press the inclined groove 12 on the unblocking plate 7. This causes the unblocking plate 7 to move downwards due to the pressure of the inclined surface of the pressing block 13 against the inclined surface of the inclined groove 12, preventing the unblocking plate 7 from obstructing the movement of the filter plate 10 to the left. When the filter plate 10 moves to the designated position, the squeezing block 13 engages with the slot 14 on the left side of the unblocking plate 7, stopping the squeezing block 13 from squeezing the unblocking plate 7. The unblocking plate 7 moves upward due to the elastic force of the spring 11, allowing the unblocking column on the unblocking plate 7 to engage with the filter plate 10, pushing out the solid impurities in the sieve holes of the filter plate 10. Then, the pin 15 is pulled out to release the handle A4 from its fixation. Then, the handle A4 is pushed to drive the scraper 9 to scrape the top of the filter plate 10, pushing the pushed-out solid impurities into the collection pipe 8.
[0039] After scraping is completed, first reset the scraper 9 and use the pin 15 to fix the handle A4. Then move the handle C6 downward to make it move the drain plate 7 downward, releasing the connection between the drain column and the filter plate 10. Then move the handle B5 to the left to make it move the filter plate 10 into the housing 1. When the handle B5 moves to a certain position to the left, it will first squeeze the inclined surface of the inclined block 16, making the inclined block 16 move upward. When the handle B5 moves to the designated position, the inclined block 16 will move downward due to gravity and engage with the handle B5, so that the handle B5 moves the filter plate 10 to the designated position.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
