Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to filtration devices for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Wastewater treatment uses filtration devices because they can effectively remove suspended solids and tiny impurities from wastewater, improving water quality and meeting discharge or reuse standards. However, existing filtration devices have shortcomings: on the one hand, some devices do not properly handle the separated solids, and the discharged solids may still pollute the environment. This is usually because the device design lacks effective collection and subsequent treatment of solids, causing solids to be discharged with the water flow or simply accumulated. On the other hand, the difficulty of installation and disassembly is also a major problem, which increases maintenance costs and time. This is often due to the complex structural design of the device, the tight connection of components, and the lack of convenient disassembly and assembly mechanisms. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a filtration device for sewage treatment, including a housing 1. A filter frame 2 is provided on the inner wall of the housing 1, and the inner wall of the housing 1 is separated by a partition. A filter screen 3 is installed on the inner wall of the filter frame 2. A rotating component 4 and a crushing component 6 are respectively provided on the inner wall of the housing 1. Two sets of installation components 5 for installing and disassembling the filter screen 3 are provided on the top of the filter frame 2. Through the cooperation of the filter frame 2 and the filter screen 3, the sewage can be easily separated into solid and liquid components. The rotating component 4 can easily drive the filter frame 2 to rotate. The crushing component 6 can easily crush the solids. The crushed solids can accelerate the biodegradation process of organic matter, improve the sewage treatment efficiency, and facilitate the subsequent discharge of solids. The installation components 5 can easily install and disassemble the filter screen 3, improving work efficiency.

[0029] The mounting assembly 5 includes a mounting bracket 51 fixed to the inner wall of the filter frame 2. A connecting rod 52 is rotatably mounted on the inner wall of the mounting bracket 51. Two sets of connecting brackets 53 are rotatably mounted on both sides of the bottom of the connecting rod 52. A connecting block 54 is rotatably mounted between the two sets of connecting brackets 53. A pressure rod 55 is fixed to the bottom of the connecting block 54, and the outer side of the pressure rod 55 is slidably connected to the inner wall of the mounting bracket 51.

[0030] By setting the mounting bracket 51, the connecting rod 52 can be rotated easily, and the pressure rod 55 can be moved up and down smoothly. By setting the connecting rod 52, the two sets of connecting brackets 53 can be adjusted easily. The two sets of connecting brackets 53 serve as transmission components. After adjustment, they can drive the connecting block 54 and the pressure rod 55 to move up and down. After the pressure rod 55 moves down to the appropriate position, the filter screen 3 can be installed. When the connecting rod 52 drives the pressure rod 55 to move up, the filter screen 3 can be disassembled. This process only requires the operator to manually pull the connecting rod 52, which improves work efficiency.

[0031] The crushing assembly 6 includes a second motor 61 fixed to one side of the housing 1. The output end of the second motor 61 is fixed with a crushing rod 62 for crushing the separated solids, and multiple sets of blades are fixed to the outside of the crushing rod 62.

[0032] By setting a second motor 61, the crushing rod 62 and multiple sets of blades can be easily driven to rotate. The combined use of the crushing rod 62 and multiple sets of blades can easily crush larger particles in solids.

[0033] Example 2:

[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the rotating component 4 includes a first motor 41 fixed to one side of the housing 1. The output end of the first motor 41 is fixed with a rotating rod 42 for driving the filter frame 2 to rotate, and the outer side of the rotating rod 42 is rotatably connected to the inner wall of the housing 1.

[0036] By setting the first motor 41, the rotating rod 42 can be easily driven to rotate. Since the rotating rod 42 and the filter frame 2 are fixed, the filter frame 2 can be flipped and adjusted when the rotating rod 42 rotates.

[0037] Specifically, a first water pump 7 is fixed on one side of the housing 1, and the outlet of the first water pump 7 is connected to a fixing frame 8. The inner wall of the fixing frame 8 is connected to multiple sets of flushing pipes 9.

[0038] By using the first water pump 7, the fixing frame 8 and the rinsing pipe 9 together, the area where solids are stored in the box 1 can be easily rinsed to avoid the residue of impurities.

[0039] Specifically, a water inlet pipe 10 is fixed to the inner wall of the housing 1, and the bottom of one end of the water inlet pipe 10 is aligned with the center of the filter screen 3. A flange 11 is fixed to the outer side of the other end of the water inlet pipe 10.

[0040] By using the inlet pipe 10 and flange 11 together, the wastewater to be treated can be easily introduced into the filter frame 2.

[0041] Example 3:

[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, a second water pump 12 is fixed on one side of the housing 1. The inlet end of the second water pump 12 is connected to a first connecting pipe 13, and the first connecting pipe 13 is a three-way type. The outlet end of the second water pump 12 is connected to a drain pipe 14.

[0044] By setting up a second water pump 12, the clean water in the tank 1 can be conveniently discharged through the pipe on the first connecting pipe 13. After closing the valve on the upper pipe, the flocculated impurities can be discharged through the two-way pipe on the first connecting pipe 13. The valve at the bottom of the first connecting pipe 13 serves as the opening and closing valve for one of the two-way pipes in the three-way pipe. After closing, the pipe on the three-way pipe will discharge the clean water in the liquid storage area. The discharged clean water can then be disinfected. Then, the valve on the upper pipe is closed, and the valve on the two-way pipe is opened to discharge the settled impurities.

[0045] Specifically, a discharge pump 15 is fixed on the other side of the housing 1. The inlet end of the discharge pump 15 is connected to a second connecting pipe 16, and the second connecting pipe 16 is a two-way type. The discharge end of the discharge pump 15 is connected to a discharge pipe.

[0046] By using the discharge pump 15 and the second connecting pipe 16 together, the crushed solid impurities can be conveniently discharged through the discharge pipe.

[0047] Specifically, support rods 17 are fixed at the four corners of the bottom of the box 1, and support seats 18 for supporting the main body are fixed at the lower ends of the four sets of support rods 17.

[0048] By using four sets of support rods 17 and four sets of support seats 18 in combination, the main body can be easily supported, thereby improving the stability of the main body.

[0049] Working principle: wastewater introduction and solid-liquid separation;

[0050] After the equipment is started, the wastewater to be treated is first introduced into the filter frame 2 through the inlet pipe 10. After the wastewater enters the filter frame 2, solid-liquid separation begins under the action of the filter screen 3. With its fine mesh, the filter screen 3 effectively intercepts solid impurities in the wastewater, allowing the separated liquid to flow smoothly into the tank 1 along the filter screen 3, while the separated solids remain in the filter frame 2. This step is the preliminary stage of wastewater treatment, laying the foundation for subsequent treatment.

[0051] Solid transfer and liquid pretreatment;

[0052] Once a certain amount of solids has accumulated in the filter frame 2, the flow of wastewater must be stopped. Then, the first motor 41 is turned on, driving the rotating rod 42 to rotate, which in turn causes the filter frame 2 to flip. When the filter frame 2 is flipped to the angle shown in Figure 4, the solids will flow into the other side of the tank 1. Since the tank 1 is separated by a partition, the separated solids and liquids will not come into contact with each other, effectively avoiding secondary pollution. At this time, an appropriate amount of flocculant is added to the area where the liquid is stored in the tank 1. The flocculant can cause the tiny particles in the liquid to agglomerate into larger flocs, which facilitates subsequent sedimentation and separation. After adding the flocculant, the first motor 41 is turned on again to reverse, driving the rotating rod 42 to flip the filter frame 2 back to its original position.

[0053] Solid pulverization and zone flushing;

[0054] To facilitate subsequent processing and discharge, the solids remaining in the housing 1 need to be crushed. The second motor 61 is turned on, which drives the crushing rod 62 to rotate. The multiple sets of blades on the crushing rod 62 rotate at high speed to fully crush the solids. The crushed solids are discharged from the equipment through the discharge pump 15, the second connecting pipe 16 and the sewage pipe. At the same time, to avoid residual impurities in the solid storage area, the first water pump 7 is turned on. The first water pump 7 discharges clean water through the fixed frame 8 and the flushing pipe 9 to the solid storage area to thoroughly flush the area and ensure that there are no residues.

[0055] Liquid sedimentation and impurity removal;

[0056] After the flocculant has been in the liquid for a period of time, the impurities in the liquid will gradually settle at the bottom of the liquid storage area inside the tank 1. At this time, the second water pump 12 is turned on to drain the water. It should be noted that the valve at the bottom of the first connecting pipe 13 should be closed first. This valve is the shut-off valve for one of the two pipes in the three-way pipe. After closing this valve, the pipe above the three-way pipe will drain the clean water in the liquid storage area. The drained clean water can be discharged after disinfection. Then, the valve on the upper pipe is closed and the valve on the two-way pipe is opened to discharge the settled impurities from the equipment, thus completing the entire sewage treatment process.

[0057] Filter 3 installation and removal;

[0058] When installing filter screen 3, first insert filter screen 3 into filter frame 2. The bottom of filter frame 2 is equipped with a support plate to prevent filter screen 3 from falling out of filter frame 2. After insertion, the operator manually pulls the connecting rod 52 downward. The connecting rod 52 drives the two sets of connecting brackets 53 to adjust downward, thereby causing the connecting block 54 to move downward. Finally, the pressure rod 55 moves downward within the mounting bracket 51. When the pressure rod 55 moves to the appropriate position, half of it is on the inner wall of filter frame 2 and the other half is on filter screen 3, thus realizing the installation of filter screen 3. To disassemble, simply reverse the above steps. The operation is simple and quick.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
