Description

Technical Field

[0001] The utility model relates to the technical field of ceramic membrane filtration, and more specifically, to a ceramic membrane filtration device for treating garbage leachate. Background Art

[0002] At present, the leachate of industrial waste or food waste is usually treated by rotating ceramic membrane filtration device. Ceramic membrane, also known as inorganic ceramic membrane, is an asymmetric membrane formed by preparing inorganic ceramic materials through a special process. The ceramic membrane tube wall is densely covered with micropores. Under the action of pressure, the raw material liquid flows inside the membrane tube or outside the membrane, small molecules (or liquids) pass through the membrane, and large molecules (or solids) are retained by the membrane, thereby achieving separation, concentration, purification and environmental protection. There are many devices that can treat leachate, such as application number: CN202221661902.6 "A Si "C ceramic membrane filtration device", a SiC ceramic membrane filtration device, comprising a filter cartridge (1), the inner cavity of the filter cartridge (1) is provided with a filter component (2), the upper part of the filter component (2) is provided with a centrifugal pump (3), the centrifugal pump (3) is connected to a hollow shaft (4), the outer wall of the hollow shaft (4) is provided with a plurality of evenly distributed through holes, the hollow shaft (4) is axially connected to the filter component (2), and the lower part of the side wall of the filter cartridge (1) is provided with a waste water pipe (5); the filter component (2) comprises an upper fixed cover (6), a lower fixed cover (7), and a lower fixed cover (8). The filter cartridge (1) is provided with a housing (7) and a silicon carbide tubular ceramic membrane (8), wherein the upper fixed cover (6) is arranged at the upper part of the inner cavity of the filter cartridge (1), the lower fixed shell (7) is arranged at the lower part of the inner cavity of the filter cartridge (1), the upper fixed cover (6) and the lower fixed shell (7) are connected via a hollow shaft (4), the upper fixed cover (6) and the lower fixed shell (7) are rotatably connected to the hollow shaft (4), a plurality of silicon carbide tubular ceramic membranes (8) are provided, and the silicon carbide tubular ceramic membranes (8) are evenly and symmetrically arranged between the upper fixed cover (6) and the lower fixed shell (7).

[0003] Although the device can flush the silicon carbide ceramic membrane with sewage without the need for an additional backwash device, and can rotate through gears to fully clean the ceramic membrane, the device can only be cleaned before work. When the filter box is full of wastewater, the box is filled with waste liquid, and the water sprayed from the nozzle cannot clean the ceramic membrane, causing the filtration effect to deteriorate during the filtration process. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 8 As shown, the utility model provides a ceramic membrane filtration device for treating landfill leachate, comprising a water outlet base 1, a filter cavity 2 is fixedly installed on the top of the water outlet base 1, and a cleaning cavity 3 is fixedly installed on the top of the filter cavity 2;

[0036] The filter mechanism is fixedly mounted at the bottom of the filter chamber 2, with one end extending to the water outlet base 1 to filter the waste water;

[0037] The fixing mechanism is fixedly installed on the top of the filter chamber 2 and is fixed with the filter mechanism, and is responsible for the fixing operation;

[0038] The water spraying mechanism is fixedly sleeved on the fixing mechanism and is located at the center of the filtering mechanism to transport waste water and clean the filtering mechanism;

[0039] The stretching mechanism is fixedly installed at the bottom of the fixing mechanism, and the other end thereof penetrates the fixing mechanism and extends upward to control the position of the filtering mechanism;

[0040] The power mechanism is fixedly mounted on the outer wall of the cleaning chamber 3, one end of which is transmission-connected to the stretching mechanism to provide power for the stretching mechanism;

[0041] Among them, the stretching mechanism includes a support rod 17 fixedly installed at the bottom of the fixing mechanism, a connecting block 19 is movably sleeved on the outer side of the support rod 17, a threaded rod 18 is movably sleeved at the center of the connecting block 19, the connecting block 19 is fixedly connected to the movable plate 12, the movable plate 12 is movably installed on the top of the fixing mechanism, the top of the support rod 17 extends upward, and a top bracket 20 is fixedly installed, and the top bracket 20 and the threaded rod 18 are rotatably connected.

[0042] When it is necessary to filter the garbage leachate, the staff installs the waste liquid pipe to the water inlet 16, and then opens the valve. The waste liquid first flows into the cleaning nozzle 15. At this time, the nozzle of the cleaning nozzle 15 is blocked by the baffle 14, so that the waste liquid cannot be sprayed out. Then the waste liquid enters the feed pipe 9 and is sprayed out from the water inlet nozzle 10 into the filter chamber 2 to clean the ceramic membrane 7 around it before operation. When the waste liquid reaches a certain level, the pressure in the filter chamber 2 increases, forcing the waste liquid into the ceramic membrane 7 to perform filtering operations. The filtered waste liquid flows from the outlet pipe 5 at the bottom of the ceramic membrane 7 into the outlet base 1 to complete the collection of the filtered waste liquid. After working for a period of time, the ceramic membrane 7 is blocked by impurities, which reduces the working efficiency.

At this time, the ceramic membrane 7 passes through the scraper 8 upward, and the scraper 8 first scrapes off the surface dirt for the initial cleaning until the limiting ring 6 is stuck on the scraper 8. At this time, the water outlet pipe 5 located at the bottom of the ceramic membrane 7 is located in the filter cavity 2. Since the water outlet pipe 5 is sealed, the waste liquid in the filter cavity 2 cannot flow out at this time. The movable plate 12 also drives the baffle 14 upward. The baffle 14 is opened, so that the water spray outlet of the cleaning nozzle 15 can start operation. At this time, the waste liquid accumulated in the filter cavity 2 is sprayed out from the cleaning nozzle 15 to clean the ceramic membrane 7. The cleaned waste liquid flows out from the wastewater outlet of the cleaning cavity 3 to complete the cleaning.

[0043] The motor 24 drives the gear 22 to rotate, thereby rotating the gear 1 21, and the gear 1 21 drives the threaded rod 18 to rotate, so that the support rod 17 moves upward, and the support rod 17 pulls up the ceramic membrane 7 and the baffle 14 to open the water outlet of the cleaning nozzle 15, so as to clean the raised ceramic membrane 7. Compared with the traditional device, the device pulls up the filtering mechanism by stretching the stretching mechanism, and at the same time, the water spraying mechanism in the cleaning cavity 3 starts to work, so that the device can clean the ceramic membrane during the filtering operation, thereby improving the work efficiency. In addition, the use of waste water for cleaning can also prevent the waste of water resources and save resources.

[0061] The working principle and use process of this utility model:

[0062] When it is necessary to filter the garbage leachate, the staff installs the waste liquid pipe to the water inlet 16, and then opens the valve. The waste liquid first flows into the cleaning nozzle 15. At this time, the nozzle of the cleaning nozzle 15 is blocked by the baffle 14, so that the waste liquid cannot be sprayed out. Then the waste liquid enters the feed pipe 9 and is sprayed out from the water inlet nozzle 10 into the filter chamber 2 to clean the ceramic membrane 7 around it before operation. When the waste liquid reaches a certain level, the pressure in the filter chamber 2 increases, forcing the waste liquid into the ceramic membrane 7 to perform filtering operations. The filtered waste liquid flows from the outlet pipe 5 at the bottom of the ceramic membrane 7 into the outlet base 1 to complete the collection of the filtered waste liquid. After working for a period of time, the ceramic membrane 7 is blocked by impurities, which reduces the working efficiency.

Thereby, the connecting block 19 is pulled up, and at this time, the connecting block 19 moves upward on the support rod 17. Since the connecting block 19 and the movable plate 12 are fixedly connected, the ceramic membrane cover 13 is movably sleeved on the top of the movable plate 12, and the movable plate 12 and the baffle 14 are fixedly connected, thereby pulling the ceramic membrane 7 and the baffle 14 upward. At this time, the ceramic membrane 7 passes through the scraper 8 upward, and the scraper 8 first scrapes off the surface dirt for the initial cleaning until the limiting ring 6 is stuck on the scraper 8. At this time, the water outlet pipe 5 located at the bottom of the ceramic membrane 7 is located in the filter cavity 2. Since the water outlet pipe 5 is sealed, the waste liquid in the filter cavity 2 cannot flow out at this time. The movable plate 12 also drives the baffle 14 upward. The baffle 14 is opened, so that the water spray outlet of the cleaning nozzle 15 can start operation. At this time, the waste liquid accumulated in the filter cavity 2 is sprayed out from the cleaning nozzle 15 to clean the ceramic membrane 7. The cleaned waste liquid flows out from the wastewater outlet of the cleaning cavity 3 to complete the cleaning.

[0063] When the water spraying mechanism cleans the filtering mechanism, the staff starts the rotating motor 25, and the rotating motor 25 drives the power gear 26 to rotate.
