Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment filtering device. Background Art

[0002] Zero discharge of industrial wastewater means that after industrial water is reused, this part of the salt content and pollutants are highly concentrated into wastewater for recycling and reuse, and no waste liquid is discharged from the factory. Common ways to treat wastewater include physical, chemical and physical-chemical methods. In the physical method, low-temperature vacuum evaporation process is often used to treat wastewater. Its main principle is: evaporation is to heat the solution to boiling so that part of the solvent is vaporized and removed to increase the solute concentration in the solution. Common treatment equipment is a low-temperature evaporator. When the low-temperature evaporator is running, the wastewater is discharged into the water storage barrel. When the wastewater in the barrel reaches the middle liquid level, water is automatically added. The water pump runs to generate vacuum, and the compressor runs to generate heat to heat the wastewater in the evaporation tank. Under vacuum, the wastewater temperature rises to about 33°C, the wastewater begins to evaporate, and then through the evaporation concentration process, the concentrate begins to be discharged. Finally, the evaporation tank is pressurized and the concentrate is pressed into the concentration tank to achieve the purpose of treating and filtering the wastewater.

[0003] There are many types of low-temperature evaporators, including standard evaporators, natural circulation externally heated evaporators, Levin evaporators, rising film evaporators, falling film evaporators, and fixed scraper evaporators. Fixed scraper evaporators are available in both vertical and horizontal types. A motor inside the shell drives the scraper on the rotating shaft to rotate. When waste liquid enters the evaporator, the scraper is tangential to it. After entering, the waste liquid is evenly distributed around the inner wall through the waste liquid distribution plate on the rotating shaft. Due to the effects of gravity and the centrifugal force of the scraper, the liquid forms a spiral downward or upward film on the inner wall (vertical) or a spiral forward film (horizontal). The secondary steam of the evaporator is discharged from the top, and the concentrated liquid is pressed into the concentration tank under the pressurized state of the evaporator tank. However, in actual treatment processes, after a period of use, the inner wall of the low-temperature evaporator often adheres to filter residue (i.e., fouling). Some of the filter residue also adheres to the steam outlet, affecting the normal discharge of steam. To this end, we propose a wastewater treatment filtration device. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0032] See also Figure 1-11The present invention provides a technical solution: a wastewater treatment and filtering device. In the actual treatment process of the existing low-temperature evaporator, since wastewater with high pollution content often precipitates scale with a certain adhesive force during treatment, after a period of use, filter residue (i.e., scale) often adheres to its inner wall, and some of the filter residue will also adhere to the steam port, affecting the normal discharge of steam. The present invention improves this, including a frame 1, a frame 2 fixedly mounted on the frame 1, and an evaporator 3 fixedly mounted inside the frame 2, wherein a treatment tank body 20 is fixedly mounted on the top of the frame 2, and the treatment tank body 20 and the evaporator 3 are connected through an air flow evaporation pipe 6, so that the water inside the evaporator 3 enters everywhere in the form of steam. The concentrated liquid with impurities in the treatment tank 20 will be pressed into the concentration tank. A rotating shaft 4 is installed inside the evaporator 3, and both ends of the rotating shaft 4 are rotatably connected to the inner wall of the evaporator 3. A servo motor 5 is fixedly installed on one side of the frame 2, and the output end of the servo motor 5 passes through the side wall of the frame 2 and is fixedly connected to the rotating shaft 4. Three stirring racks 41 are fixedly installed on the rotating shaft 4, and the three stirring racks 41 are installed at equal angles on the rotating shaft 4, that is, the angle difference between the three stirring racks 41 is 120°. A plurality of spoiler frames 42 are fixedly installed on one side of each stirring rack 41, wherein the spoiler frame 42 is installed obliquely on the side wall of the stirring rack 41, and a hinged closed plate frame 4 is installed on the top of each spoiler frame 42. 3, further explained, the hinged closed plate frame 43 and the inner wall of the spoiler frame 42 are connected by a damping shaft. When subjected to the force inside the spoiler frame 42, the hinged closed plate frame 43 can be opened, and the air flow evaporation duct 6 is located at one end inside the evaporator 3 and is fixedly mounted with a filter disc 7, and an inner wall of one side of the evaporator 3 is fixedly mounted with an inner frame 8, wherein the filter disc 7 is located inside the inner frame 8, that is, the gas enters the inner frame 8 and enters the air flow evaporation tube through the filter disc 7, a circular sleeve 9 is fixedly mounted on the bottom of the inner frame 8, and a flexible brush body 10 slidably connected to its inner wall is installed inside the inner frame 8, further explained, the flexible brush body 10 is used to clean impurities on the surface of the filter disc 7, the bottom of the flexible brush body 10 A driving sleeve 11 is fixedly installed, and a sliding column 12 rotatably connected to the driving sleeve 11 is symmetrically installed on the inner wall of the driving sleeve 11. A transmission shaft 13 rotatably connected to the circular sleeve 9 is installed inside the circular sleeve 9. The end of the driving sleeve 11 passes through the top of the circular sleeve 9 and extends into the interior thereof. The transmission shaft 13 is located inside the driving sleeve 11, and an adjustment groove 14 is provided on the outer wall of the transmission shaft 13. As a further definition in the present invention, the adjustment groove 14 is composed of an annular groove body 141, an arc-shaped upward groove body 142 and an arc-shaped downward groove body 143. The arc-shaped upward groove body 142 and the arc-shaped downward groove body 143 are in a communicating state, wherein the two ends of the annular groove body 141 are respectively communicated with the arc-shaped upward groove body 142 and the arc-shaped downward groove body 143.The distance between the end of the arc-shaped upward groove body 142 and the end of the arc-shaped downward groove body 143 (the end at the lowest point) is one-third of the annular groove body 141, and the sliding column 12 slides within the adjustment groove 14. The end of the transmission shaft body 13 passes through the bottom of the circular sleeve 9 and extends to the outside, and a circular panel 15 is fixedly installed at the end, and a plurality of force rod frames 16 are fixedly installed on the circular panel 15, wherein a force disc 17 is fixedly installed on the rotating shaft body 4, and a plurality of force rod frames 18 are fixedly installed on the force disc 17, and the force rod frames 16 are located on the movement trajectory of the force rod frames 18, that is, when the rotating shaft body 4 rotates, the wastewater inside the evaporator 3 is gasified under the action of low temperature and high pressure. The filter disc 7 intercepts impurities. During the rotation of the rotating shaft 4, the force-applying disc 17 thereon drives the force-applying rod frame 18 to rotate. During the rotation of the force-applying rod frame 18, a force is applied to the force-receiving rod frame 16, that is, the force-receiving rod frame 16 is subjected to the force to drive the circular panel 15 to rotate. At the same time, a circular disc frame 111 is fixedly installed on the outer wall of the driving sleeve 11, and a spring body 112 is connected between the circular disc frame 111 and the inner wall of the top of the circular sleeve 9, and a plurality of combing rod frames 81 are fixedly installed on the bottom of the inner frame 8. The combing rod frames 81 are located on the motion trajectory of the flexible brush body 10 to clean impurities on the flexible brush body 10.

[0033] Specifically, when the wastewater enters the evaporator 3, the servo motor 5 is started, and the output end of the servo motor 5 drives the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the wastewater is dispersed through the stirring rod frame and the spoiler frame 42 thereon, so that the wastewater can quickly reach the boiling point. During the rotation of the rotating shaft 4, the force disc 17 is driven to rotate synchronously, and the force rod frame 18 on the force disc applies a force to the force rod frame 16 during the rotation, so that the force rod frame 16 drives the force disc to rotate after receiving the force. There are multiple racks 16 fixedly installed on the circular panel 15, one of the force-applying rod racks 18 applies a force to one of the force-receiving rod racks 16 and causes it to rotate. When the force-applying rod rack 18 no longer acts on the force-receiving rod rack 16, the other force-receiving rod rack 16 moves to the motion trajectory of the next force-applying rod rack 18, thereby causing the transmission shaft 13 to rotate inside the circular sleeve 9. Further explanation: in the initial state, the sliding column 12 on the inner wall of the driving sleeve 11 is located in the annular groove 141. When the transmission shaft 13 rotates, the sliding column 12 will be rotated in the annular groove. 141 changes, when the sliding column 12 is located at the lowest end of the arc-shaped upward groove 142, the force-bearing rod frame 16 is acted upon by the force-applying rod frame 18, so that when the circular panel 15 rotates, the arc-shaped upward groove 142 on the transmission shaft 13 will apply a force to the sliding column 12, that is, the driving sleeve 11 performs a directional upward movement in the circular sleeve 9, and during the rising process, the spring body 112 is compressed by the circular disc frame 111 thereon, and the flexible brush body 10 on the driving sleeve 11 will press the surface of the filter disc 7 during the rising process. Impurities are cleaned. When one of the force-applying rods 18 acts on the force-receiving rod 16, if the sliding column 12 is initially located at the lowest end of the arc-shaped upward groove 142, it will pass through the arc-shaped upward groove 142 and move to the lowest end of the arc-shaped downward groove 143 under the action of the spring body 112, thereby causing the flexible brush body to perform a lifting action, and pass through the combing rod 81 during the descending process. The combing rod 81 cleans the impurities on the flexible brush body 10, so that the surface of the filter disc 7 can be effectively cleaned next time, thereby avoiding the situation where the filter residue blocks the filter disc 7;

[0034] Furthermore, during the wastewater treatment process of the evaporator 3, filter residue with strong adhesion is often attached to its inner wall. In order to prevent the filter residue on the inner wall of the top of the evaporator 3 from affecting the escape of gas (the gas may carry the filter residue on the inner wall through the filter disk 7 when passing through the inner wall of the top of the evaporator 3), the present invention is fixedly installed with a connecting shaft 44 between the side wall of the stirring frame 41 and the rotating shaft 4, and a spiral spoiler blade 45 is fixedly installed on the outer wall of the connecting shaft 44. The spiral spoiler blade 45 increases the turbulence degree in the wastewater treatment process so that the wastewater can be quickly heated to the boiling point. Moreover, since the spoiler frame 42 is installed at an angle on the stirring frame 41, the wastewater treatment efficiency can also be effectively improved. Each spoiler frame 42 is internally installed with a flexible brush body 46 slidably connected to its inner wall, and the flexible brush body 46 is fixedly installed. An extension column 47 is installed at the bottom, and a pulley 48 rotatably connected to the extension column 47 is installed at the end of the extension column 47. The pulley 48 is located inside the rotating shaft 4. It is further explained that during the wastewater treatment process of the evaporator 3, the highest liquid level of the wastewater is close to two-thirds of the evaporator 3. A drive shaft 19 is installed inside the rotating shaft 4, and the drive shaft 19 and the rotating shaft 4 are rotatably connected, wherein a plurality of arc-shaped sliders 191 are fixedly installed on the drive shaft 19, and the arc-shaped sliders 191 correspond one-to-one to the pulley 48. The arc-shaped sliders 191 are located at the highest area of ​​the drive shaft 19, and the arc-shaped sliders 191 are located on the motion trajectory of the pulley 48. An action disc 471 is fixedly installed on the outer wall of the extension column 47, and a reset spring 472 is connected between the action disc 471 and the inner wall of the connecting shaft 44.

[0035] Specifically, when the rotating shaft 4 is rotating, the stirring frame 41 and the multiple spoiler frames 42 thereon rotate synchronously with it, and the pulley member 48 also rotates with it on the driving shaft 19. When one of the pulley members 48 moves to the arc-shaped slider 191, the corresponding spoiler frame 42 moves close to the top inner wall of the evaporator 3, and the multiple spoiler frames 42 on the other two stirring frames 41 are located in the wastewater. The hinged closing plate frame 43 is in a closed state to prevent wastewater from infiltrating the surface of the flexible brush body 46. The pulley member 48 in contact with the surface of the arc-shaped slider 191 will perform an upward movement under the action of the arc-shaped slider 191, that is, the pulley member 48 drives the extension column 47 to perform a synchronous upward movement, that is, under the action of the extension column 47, The flexible brush body 2 46 pushes open the hinged closing plate frame 43 and contacts the top inner wall area of ​​the evaporator 3. In the process of rotating with the rotating shaft 4, the top inner wall area of ​​the evaporator 3 is effectively cleaned. When the flexible brush body 2 46 rotates to near the wastewater, the pulley member 48 leaves the surface of the arc-shaped slider 191 and contacts the surface of the drive shaft 19 under the action of the reset spring 472. That is, the flexible brush body 2 46 enters the spoiler frame 42 at this time, and the hinged closing plate frame 43 returns to the closed state under the action of the damping shaft and the existing torsion spring. Through the structural design of the present invention, the flexible brush body 2 46 can effectively clean the top inner wall of the evaporator 3, thereby avoiding the filter residue (of the top inner wall of the evaporator 3) from affecting the gas escape condition.
