Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for treating a mixture of sludge and wastewater. Background Technology

[0002] Oily waste and sewage mixtures refer to liquid waste containing oily substances mixed with other impurities generated in industrial production, ship operation, or daily life. Oily waste and sewage mixture treatment devices are equipment specifically designed to separate and treat oily wastewater, and are widely used in catering, industry, shipbuilding, and other fields.

[0003] According to announcement number CN218794493U, a wastewater treatment device capable of repeated filtration includes a base, a support leg fixedly connected to the top surface of the base, a housing fixedly connected to the top surface of the support leg, a groove inside the right end face of the housing, a fixing plate fixedly connected inside the groove, a second spring fixedly connected to one end of the fixing plate, a pull plate fixedly connected to the other end of the second spring, a locking block fixedly connected to the other end of the pull plate, a filter plate engaged at the other end of the locking block, and a third handle fixedly connected to the right end face of the filter plate. In this utility model, by using the fixing plate, the second spring, the pull plate, and the locking block, the filter plate can be temporarily fixed by engaging with the filter plate. Pulling the pull plate allows the filter plate to be pulled out of the housing, thus solving the problem that the filter plate is difficult to clean and replace due to excessive adsorption of impurities during the filtration of impurities in wastewater.

[0004] However, in the aforementioned patent, the wastewater enters the tank and is discharged directly after only one contact with the filter plate and filter screen. This method of adsorbing impurities means that the impurities in the wastewater are not fully captured by the filter components before being discharged from the tank, resulting in poor filtration and thus affecting the use of the mixture treatment device.

[0022] Please see Figures 1-7This utility model provides a technical solution: a device for treating a mixture of oily sludge and sewage, comprising a separation tank 1, a feed pipe 2, and an auxiliary mechanism 6.

The auxiliary mechanism 6 includes an end cap 601, a filter cylinder 602, a servo motor 603, a rotating column 604, a stirring rod 605, a lifting ring 606, a limiting pin 607, a fixing pin 608, an electric push rod 609, a base 610, a transmission rod 611, a limiting seat 612, a fixing seat 613, and a first spring 6. 14. A fixed column 615 and a second spring 616 are connected to the top of the outer wall of the treatment tank 5. An end cap 601 is connected to the top of the outer wall of the treatment tank 5. A limiting groove is opened in the middle of the bottom end of the end cap 601, and a filter cylinder 602 is connected in the limiting groove. The filter cylinder 602 has openings at the top and bottom. A servo motor 603 is installed in the middle of the top of the end cap 601. A rotating column 604 is connected to the output end of the servo motor 603. A stirring rod 605 is sleeved on the bottom of the outer wall of the rotating column 604. A lifting ring 606 is welded to the outer side of the top of the end cap 601, and a limiting pin 607 with equal included angle is welded to the outer side of the bottom end of the end cap 601. A fixing pin 608 is connected through the top of the filter cylinder 602. The stirring rod 605 has a "+" shaped structure. The lifting ring 606... The components 606 are arranged in a cross shape, the fixing pins 608 are arranged in a triangle, and the top of the outer wall of the servo motor 603 is fixedly connected to the electric push rod 609; the output end of the electric push rod 609 is connected to the base 610, and the bottom outer side of the base 610 is rotatably connected to the transmission rod 611, and the bottom end of the transmission rod 611 is rotatably connected to the limit seat 612. The transmission rods 611 are arranged at equal angles; the limit seat 612 is internally slidably connected to the fixed seat 613, and the fixed seat 613 has a U-shaped structure. The bottom end of the outer wall of the fixed seat 613 is welded to the end cover 601, and the bottom end of the outer wall of the limit seat 612 is welded to the fixing pins 608; a first spring 614 is connected to the inner wall of the fixed seat 613, and the first spring... One side of the outer wall of 614 is connected to the limiting seat 612. The limiting seat 612 and the fixing pin 608 form an "L" shape. The limiting seat 612, the fixing seat 613 and the first spring 614 form an elastic telescopic mechanism. The base 610 has a fixed column 615 slidably connected inside. The second spring 616 is sleeved in the middle of the outer wall of the fixed column 615. The bottom end of the outer wall of the fixed column 615 is welded to the end cover 601. The end cover 601, the fixed column 615 and the second spring 616 form an elastic telescopic mechanism. The upper and lower sides of the second spring 616 are connected to the base 610 and the end cover 601 respectively. The fixed columns 615 are triangularly distributed. The stirring rods 605 are evenly distributed on the rotating column 604.

[0023] In specific implementation, during the process of treating oil-water mixtures through the mixture treatment device, the sewage at the bottom of the separation tank 1 enters the treatment tank 5 through the conveying pipe 4. First, the servo motor 603 on the top of the end cover 601 is started. Since the output end of the servo motor 603 is connected to the rotating column 604, the start of the servo motor 603 will drive the rotating column 604 to rotate. At this time, the limit pin 607 is inserted into the top of the treatment tank 5, thereby limiting the end cover 601 to prevent it from rotating arbitrarily. Then, the rotation of the rotating column 604 drives the stirring rod 605 to rotate, thereby forming a negative pressure vortex in the treatment tank 5. This causes the sewage in the treatment tank 5 to flow from the outside to the center, and then move up from the center to contact the filter cartridge 602. This forms a cycle, allowing the sewage to repeatedly contact the filter cartridge 602 to adsorb impurities, thereby improving the adsorption effect of impurities and thus improving the filtration effect of the filter cartridge 602 on impurities in the sewage.

[0024] When the inner wall of the filter cartridge 602 is filled with too many impurities and needs to be cleaned, since the top of the end cap 601 is connected to the lifting ring 606, the lifting strap or hook should be connected to the lifting ring 606 first, so that the staff can operate the crane to lift the end cap 601 and move it upward. Since the end cap 601 is connected to the filter cartridge 602 at this time, the upward movement of the end cap 601 will drive the filter cartridge 602 to move upward together until the filter cartridge 602 is removed from the treatment tank 5 for cleaning.

[0025] When the filter cartridge 602 needs to be disassembled for cleaning or replacement, first start the electric push rod 609 at the top of the servo motor 603. Since the top output end of the electric push rod 609 is connected to the base 610, the retraction of the electric push rod 609 will drive the base 610 to move downward along the fixed column 615. The downward movement of the base 610 will compress the second spring 616, causing it to deform. Then, the second spring 616 will reset to assist the base 610 to move upward. And because the base 610 and the transmission rod 611 The base 610 is rotatably connected to the base 610. When the base 610 moves downward, it causes the transmission rod 611 to rotate. This changes the angle between the transmission rod 611 and the base 610, generating a thrust on the limiting seat 612. This causes the limiting seat 612 to move along the fixed seat 613 towards the servo motor 603. Since the limiting seat 612 is connected to the fixing pin 608, the movement of the limiting seat 612 causes the fixing pin 608 to move as well. Furthermore, the movement of the limiting seat 612 compresses the first spring. The deformation caused by spring 614 is then resolved by the reset auxiliary limit seat 612 of spring 614 until multiple fixing pins 608 disengage from the top of filter cylinder 602, thus releasing the fixation of filter cylinder 602. At this point, the filter cylinder 602 can be removed for cleaning without repeatedly turning multiple sets of bolts. When filter cylinder 602 needs to be replaced, simply move the top of the intact filter cylinder 602 into the limiting groove at the bottom of end cover 601, then activate the electric push rod 609 to extend and move the base 610 upward. At this time, spring 616 resets the base 610 upward, and spring 614 resets the limit seat 612 away from the servo motor 603 until the fixing pins 608 are inserted into the inner wall of filter cylinder 602, thus completing the replacement of filter cylinder 602. This facilitates circulation filtration and disassembly and cleaning of filter cylinder 602 when used in the waste oil and wastewater mixture treatment device.

[0026] In summary, when using this oil and wastewater mixture treatment device, the oil-water mixture is first introduced into the separation tank 1 through the feed pipe 2. After a period of time, the oil droplets are separated by gravity due to the density difference between oil and water. The floating oil is then extracted from the separation tank 1 through the oil extraction pipe 3. The wastewater at the bottom of the separation tank 1 is then introduced into the treatment tank 5 through the conveying pipe 4. The wastewater is then filtered by the filter components in the treatment tank 5 to remove impurities. This is existing technology and will not be elaborated further. The auxiliary mechanism 6 enables… The wastewater forms a negative pressure vortex in the treatment tank 5, which then circulates, causing the wastewater to repeatedly contact the filter cartridge 602 to adsorb impurities and improve the filtration effect. At the same time, multiple fixing pins 608 are simultaneously disengaged from the filter cartridge 602, thereby removing the fixing of the filter cartridge 602. At this time, the staff can remove the filter cartridge 602 for cleaning. Therefore, the filter cartridge 602 can be disassembled and cleaned without repeatedly turning multiple sets of bolts, which facilitates subsequent installation. The contents not described in detail in this description are prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
