Description

Technical Field

[0001] This application relates to the field of wastewater filtration technology, and in particular to a wastewater filter residue device. Background Technology

[0002] As is well known, wastewater filtration and discharge are extremely important in industrial production and daily life. Especially in the brewing industry, the production of koji (fermentation starter) and cleaning processes generate a large amount of small residue (diameter ≤ 4mm), which frequently clogs drainage pipes, preventing wastewater from entering the sewage network and posing a significant environmental compliance risk. Therefore, it is necessary to upgrade these systems.

[0003] Currently, most workshops have completed the renovation and basically adopt a single filtration structure, mainly consisting of a single, integrated filter screen with a fixed 1.5mm mesh size. Wastewater to be filtered is poured directly into the filtration device, where the filter screen traps the impurities, and the filtered wastewater is discharged through the screen.

[0004] However, the modified filter frame still has some defects in use: 1) The slag filtration effect is poor, and it is easy to accumulate on the screen, which leads to blockage of the filter channel, a significant decrease in filtration efficiency, and the inability to drain the accumulated water; 2) The overall volume is large, occupies a lot of space, and the entire filter frame needs to be cleaned during cleaning, which is cumbersome and consumes a lot of manpower and time costs, making it difficult to meet the needs of high-efficiency production.

[0005] Therefore, there is an urgent need for a device to solve the technical problems mentioned above. Utility Model Content

[0006] Based on this, this application provides a wastewater filtration device that, through reasonable partitioned filtration and detachable connection, can effectively solve the problems of poor filtration effect, easy clogging of filtration channels and inconvenient cleaning, thereby achieving the effects of improving filtration efficiency, reducing the probability of mesh clogging and facilitating cleaning.

[0007] To solve the above problems, a wastewater filter cake device is provided, comprising:

[0008] The filter cake tank is equipped with movable baffles inside, which divide the filter cake tank into adjacent sedimentation zones and filtration zones. The height of the movable baffles is lower than the height of the filter cake tank.

[0009] The sedimentation zone has a detachable debris filter frame inside.

[0010] The debris filter frame has a primary mesh design on its side walls and bottom to separate debris and wastewater in the first stage.

[0011] The filtration zone has a two-stage mesh design at the bottom to separate debris from wastewater in two stages; the mesh diameter of the debris filter frame is larger than that of the mesh at the bottom of the filtration zone.

[0012] An alternative is to set the mesh diameter of the debris filter frame to mm;

[0013] The mesh diameter at the bottom of the filtration zone is set to mm.

[0014] An alternative is a sedimentation zone with a sloping bottom to allow for the natural discharge of debris and water from the bottom of the sedimentation zone.

[0015] An alternative solution is to install a limit component between the movable baffle and the filter cake tank;

[0016] Limiting components are used to limit the movement of the baffle.

[0017] An alternative solution is a limiting component, including a first limiting plate and a second limiting plate fixed to the filter cake tank, with a limiting groove formed between the first limiting plate and the second limiting plate; a movable baffle is pulled out along the height direction of the limiting groove to control the connection and isolation between the sedimentation zone and the filtration zone.

[0018] An alternative is to install a positioning component between the sedimentation zone and the debris filter frame to position the debris filter frame when it is placed in the sedimentation zone.

[0019] An alternative is a positioning component, including a positioning plate fixed to the sedimentation zone, a connecting block fixed to the debris filter frame, and a positioning block fixed to the connecting block.

[0020] The positioning plate has a positioning groove along its length, and the positioning block is inserted into the positioning groove.

[0021] An alternative is that the positioning groove and the positioning block are matched, and both the positioning groove and the positioning block are T-shaped.

[0022] An alternative is to have two sets of both the limit component and the positioning component;

[0023] Two sets of limiting components are located on opposite inner walls of the filter cake tank;

[0024] Two sets of positioning components are located on opposite sides of the debris filter frame.

[0025] An alternative solution is to provide a debris filter frame with a handle for retrieving the debris filter frame.

[0026] The filter cake tank is equipped with a handle for moving the filter cake tank.

[0027] Beneficial effects:

[0028] By using a reasonable partitioned filtration system and a detachable connection, the problems of poor slag filtration, easy clogging of filtration channels, and inconvenient cleaning can be effectively solved, thereby improving slag filtration efficiency, reducing the chance of mesh clogging, and facilitating cleaning.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Therefore, they have no substantial technical significance.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In existing technologies, a single filtration structure is generally used, mainly consisting of a single, integral filter screen with a fixed 1.5mm mesh size. Wastewater to be filtered is poured directly into the filtration device, where the filter screen traps impurities, and the filtered wastewater is discharged through the screen. However, the aforementioned modified filter frame still has some drawbacks during use: 1) Poor impurity filtration, easily accumulating on the screen, leading to clogging of the filter channels, a significant decrease in filtration efficiency, and the inability to drain accumulated water; 2) Large overall size, occupying a lot of space, and requiring thorough cleaning of the entire filter frame, which is cumbersome, consumes significant manpower and time, and is difficult to meet the needs of high-efficiency production.

[0039] Therefore, this application provides a wastewater filter residue device. Through reasonable partitioned filtration and detachable connection, it can effectively solve the problems of poor residue filtration effect, easy clogging of filtration channels and inconvenient cleaning, thereby achieving the effects of improving residue filtration efficiency, reducing the probability of mesh clogging and facilitating cleaning.

[0040] The following detailed description of a wastewater filter cake device provided in this embodiment, with reference to the accompanying drawings, is provided in detail. Figures 1-3As shown, it includes: a filter cake tank 1, with an internal movable baffle 2 that divides the filter cake tank 1 into an adjacent sedimentation zone 11 and a filtration zone 12, the height of the movable baffle 2 being lower than the height of the filter cake tank 1; a sedimentation zone 11, with a detachably connected debris filter frame 3 inside; the debris filter frame 3 having a primary mesh design on its side walls and bottom for primary separation of debris and wastewater; and a filtration zone 12 having a secondary mesh design at its bottom for secondary separation of debris and wastewater; wherein the mesh diameter of the debris filter frame 3 is larger than the mesh diameter of the bottom 12 of the filtration zone.

[0041] Here, as Figures 1-3 As shown, the wastewater filter cake device includes a filter cake tank 1, which is rectangular with an open top and has a compact overall size, occupying little space. Inside the filter cake tank 1, there is a movable baffle 2, which is rectangular in shape. The length of the movable baffle 2 is the same as the width of the filter cake tank 1. The movable baffle 2 divides the filter cake tank 1 into an adjacent sedimentation zone 11 and a filtration zone 12. The movable baffle 2 can be pulled out along the height direction of the filter cake tank 1, and the height of the movable baffle 2 is lower than the height of the filter cake tank 1, so that wastewater can flow from the sedimentation zone 11 into the filtration zone 12.

[0042] The sedimentation zone 11 contains a debris filter frame 3, which is an independent and detachable structure. It is fitted and installed inside the upper part of the sedimentation zone 11, with a certain gap between the bottom of the debris filter frame 3 and the bottom of the sedimentation zone 11. The debris filter frame 3 is rectangular with an open top, and its sidewalls and bottom are designed with a primary mesh. When wastewater to be filtered is poured into the sedimentation zone 11 from the top, larger debris is trapped by the debris filter frame 3, while the wastewater passes through the debris filter frame 3 and falls to the bottom of the sedimentation zone 11, thus achieving primary separation of debris and wastewater, i.e., trapping larger impurities.

[0043] The filtration zone 12 has a two-stage mesh design at the bottom. As the amount of wastewater poured into the sedimentation zone 11 increases, the water level rises to the top of the movable baffle 2. Since the height of the movable baffle 2 is lower than the height of the filter cake tank 1, when the water level reaches the height of the movable baffle 2, the wastewater overflows through the top of the movable baffle 2 into the filtration zone 12. The wastewater is then filtered again in the filtration zone 12 and discharged from the bottom. Furthermore, since the mesh diameter of the debris filter frame 3 is larger than the mesh diameter at the bottom of the filtration zone 12, two-stage separation of debris and wastewater can be achieved, i.e., smaller impurities are retained.

[0044] The above operation, by adding a pre-filtration zone, namely the debris filter frame 3, initially intercepts large particles of sludge, preventing them from entering the sedimentation zone 11 and the water filtration zone 12, thereby reducing the probability of mesh clogging, reducing the risk of clogging of the filtration channel, and making the filtration process smoother; by setting up the water filtration zone 12, impurities in the wastewater are intercepted again, thereby improving the filtration effect.

[0045] Preferred, refer to Figures 1-3 As shown, the mesh diameter of the debris filter frame 3 is set to 2mm;

[0046] The mesh diameter at the bottom of the filtration zone 12 is set to 1mm.

[0047] Here, as Figures 1-3 As shown, the mesh diameter of the debris filter frame 3 can generally be set to 2mm, thus enabling the interception of impurities larger than 2mm. The mesh diameter at the bottom of the water filtration zone 12 can generally be set to 1mm, thus enabling the interception of impurities larger than 1mm but smaller than 2mm.

[0048] The above operation, by setting different mesh diameters, can intercept impurities of different sizes in sewage, especially sludge particles of 1-4mm, thereby avoiding sewage pipe network blockage and improving filtration efficiency.

[0049] Preferred, refer to Figures 1-3 As shown, the sedimentation zone 11 is inclined at the bottom to facilitate the natural discharge of debris and water from the bottom of the sedimentation zone 11.

[0050] Here, as Figures 1-3 As shown, the sedimentation zone 11 has a bottom that slopes from top to bottom, i.e., a ramp structure. This allows for the natural discharge of debris and water from the bottom of the sedimentation zone 11 by gravity, without the need for additional power. This is energy-saving, environmentally friendly, and easy to clean.

[0051] The above operations can reduce the cleaning time from the traditional 5 minutes to less than 2 minutes, thereby reducing labor costs.

[0052] Preferably, refer to Figures 1-2 As shown, a limiting component 4 is provided between the movable baffle 2 and the filter tank 1; the limiting component 4 is used to limit the movable baffle 2.

[0053] In one feasible way, such as Figures 1-2 As shown, the limiting component 4 includes a first limiting plate 41 and a second limiting plate 42 fixed to the inner wall of the filter tank 1, and a limiting groove 43 is formed between the first limiting plate 41 and the second limiting plate 42; the movable baffle 2 is pulled out along the height direction of the limiting groove 43 to control the connection and isolation between the sedimentation zone 11 and the filtration zone 12.

[0054] Here, the limiting component 4 includes a first limiting plate 41 and a second limiting plate 42 fixedly connected to the inner wall of the filter cake tank 1. The height of the first limiting plate 41 and the second limiting plate 42 is equal to the height of the filter cake tank 1, and the first limiting plate 41 and the second limiting plate 42 are arranged opposite to each other. A limiting groove 43 is formed between the first limiting plate 41 and the second limiting plate 42. The limiting groove 43 is rectangular, and the width of the limiting groove 43 is adapted to the width of the movable baffle 2. One side of the movable baffle 2 can be located in the limiting groove 43 and can be pulled out along the height direction of the limiting groove 43.

[0055] The above operation, the setting of the movable baffle 2, can flexibly control the connection and isolation between the sedimentation zone 11 and the filtration zone 12, ensuring the fullness of the sedimentation process; and the setting of the first limiting plate 41 and the second limiting plate 42 can limit the movable baffle 2, providing further guarantee for the realization of the function of the movable baffle 2.

[0056] Preferably, refer to Figures 3-4 As shown, a positioning component 5 is provided between the sedimentation zone 11 and the debris filter frame 3, which is used to position the debris filter frame 3 when it is placed in the sedimentation zone 11.

[0057] In one feasible way, such as Figures 3-4 As shown, the positioning component 5 includes a positioning plate 51 fixed to the sedimentation zone 11, a connecting block 52 fixed to the debris filter frame 3, and a positioning block 53 fixed to the connecting block 52; the positioning plate 51 has a positioning groove 511 along its length direction, and the positioning block 53 is inserted into the positioning groove 511.

[0058] Here, the positioning component 5 includes a positioning plate 51 fixedly connected to the inner wall of the sedimentation zone 11, a connecting block 52 fixedly connected to the outer wall of the debris filter frame 3, and a positioning block 53 fixedly connected to the connecting block 52. The positioning plate 51 has a positioning groove 511 along its length, which is adapted to the positioning block 53, and both the positioning groove 511 and the positioning block 53 are T-shaped. When the debris filter frame 3 is placed into or removed from the sedimentation zone 11, the positioning block 53 is inserted into the positioning groove 511.

[0059] The above operation allows for a detachable connection between the debris filter frame 3 and the sedimentation zone 11, facilitating separate cleaning of the debris filter frame 3 and the sedimentation zone 11, thereby reducing cleaning time and making maintenance more convenient. Furthermore, the positioning component 5 can limit the movement of the debris filter frame 3, making it more stable within the sedimentation zone 11.

[0060] Preferably, refer to Figures 1-3 The limiting component 4 and the positioning component 5 are each provided in two sets; the two sets of limiting components 4 are located on the two opposite inner walls of the filter cake tank 1; the two sets of positioning components 5 are located on the opposite sides of the debris filter frame 3.

[0061] Here, as Figures 1-3 As shown, there are two sets of limiting components 4, which are located on opposite inner walls of the filter cake tank 1. The two sides of the movable baffle 2 can be located within the two sets of limiting components 4 respectively, so as to limit the movement of the movable baffle 2.

[0062] The positioning component 5 is provided in two sets, which are located on opposite sides of the debris filter frame 3. When the debris filter frame 3 is placed into or removed from the sedimentation area 11, the positioning components 5 can limit the movement of both sides of the debris filter frame 3.

[0063] The above operation, by setting both the limiting component 4 and the positioning component 5 as two sets, can further limit the movement of the movable baffle 2 and the debris filter frame 3, and improve the stability of the pull-out of the movable baffle 2 and the insertion of the debris filter frame 3.

[0064] Preferably, refer to Figures 1-3 The debris filter frame 3 is equipped with a filter frame handle 31 for lifting the debris filter frame 3; the filter cake tank 1 is equipped with a filter cake handle 13 for moving the filter cake tank 1.

[0065] Here, as Figures 1-3 As shown, filter frame handles 31 are rotatably connected to the two opposite inner sides of the debris filter frame 3. The filter frame handles 31 are concave in shape, making it convenient for workers to put the debris filter frame 3 into or take it out of the sedimentation zone 11. Filter tank handles 13 are rotatably connected to the two opposite inner sides of the filter cake tank 1, making it convenient for workers to move the filter cake tank 1.

[0066] The above operations facilitate the removal of the debris filter frame 3 by setting the filter frame handle 31, and facilitate the movement of the filter residue tank 1 by setting the filter tank handle 13.

[0067] The implementation principle of this embodiment is as follows: In use, the debris filter frame 3 is first placed in the sedimentation zone 11, the movable baffle 2 is inserted into the limiting groove 43, and the positioning block 53 is inserted into the positioning groove 511. The wastewater to be filtered is poured in from the top of the sedimentation zone 11. At this time, larger debris is intercepted by the debris filter frame 3, while the wastewater passes through the debris filter frame 3 and falls to the bottom of the sedimentation zone 11. As the amount of wastewater increases, the wastewater settles at the bottom of the sedimentation zone 11 until the water level rises to the top of the movable baffle 2. Since the height of the movable baffle 2 is lower than the height of the filter cake tank 1, the wastewater overflows through the top of the movable baffle 2 into the filtration zone 12, where it is filtered again before being discharged from the bottom.

[0068] After use, the debris filter frame 3 is lifted out of the sedimentation zone 11 using the filter frame handle 31, the trapped debris is poured out, and it is put back into the sedimentation zone 11 for cleaning. The movable baffle 2 is pulled out. Since the bottom of the sedimentation zone 11 is designed with a slope structure, the water and other sludge deposited at the bottom of the sedimentation zone 11 will automatically slide into the water filtration zone 12 under the action of gravity. Finally, it is discharged after being filtered again through the bottom of the water filtration zone 12. There is no need for manual cleaning of the bottom of the sedimentation zone 11, which simplifies the cleaning process.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
