Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for cleaning waste incinerator slag. Background Technology

[0002] Waste incinerators are devices used to incinerate and process waste. The waste burns in the furnace and becomes exhaust gas, which enters the secondary combustion chamber. Under the forced combustion of the burner, the gas is completely burned and then enters the spray dust collector. After dust removal, the gas is discharged into the atmosphere through the chimney. When cleaning the slag in the waste incinerator, various pollutants contained in the waste will dissolve into the cleaning water. Therefore, the wastewater usually needs to be treated to meet environmental standards before it can be discharged.

[0003] When treating wastewater, various chemicals need to be added to adjust pH, disinfect, remove nutrients such as phosphorus, and remove heavy metals or special pollutants. However, currently, the addition of chemical powders to wastewater from slag cleaning is not very effective. Chemical powder is usually poured directly into the wastewater pool from above the wastewater surface, either manually or mechanically. The powder needs to gradually dissolve into the wastewater from top to bottom, which is not only slow in mixing efficiency, but also makes it easy for the powder to clump and float on the surface, affecting the mixing of the powder and the wastewater. Summary of the Invention

[0004] This invention provides a wastewater treatment device for cleaning waste incinerator slag, aiming to solve the problems in related technologies where the medicinal powder needs to be gradually dissolved into the wastewater from top to bottom, resulting in slow mixing efficiency and easy clumping.

[0005] The wastewater treatment equipment for cleaning waste incinerator slag of the present invention includes a tank body, and a hopper is provided inside the tank body for temporarily storing powdered chemicals. The tank has at least one mixing cylinder inside, which is connected to the hopper and can revolve and rotate inside the tank. The side wall of the mixing cylinder has a through groove. The top of the mixing cylinder is equipped with a sealing assembly to control the connection or isolation between the hopper and the interior of the mixing cylinder; The mixing cylinder is equipped with an adjustment plate that can move up and down inside the mixing cylinder as it rotates. The up and down movement of the adjustment plate is coupled with a baffle for opening and closing the through slot and a drive component for switching the opening and closing state of the sealing component. This allows the adjustment plate to open the through slot and close the sealing component during descent, and to close the through slot and open the sealing component during ascent.

[0006] Preferably, the mixing cylinder is vertically rotatably equipped with an installation shaft, the baffle is fixed on the installation shaft and located in the through groove, the installation shaft is provided with a guide groove, the guide groove includes at least one spirally extending inclined groove and two vertical grooves respectively connected to the two ends of the inclined groove, and the adjusting plate is fixed with a protrusion that slides in the guide groove. When the protrusion is located in the vertical groove, the baffle remains in a fixed open / closed state; when the protrusion slides along the inclined groove, it drives the mounting shaft to rotate to switch the open / closed state of the baffle; thus, by adjusting the lifting and lowering of the adjustment plate, the state of the baffle can be switched better to facilitate the filling and discharge of the powder.

[0007] Preferably, the sealing assembly includes an upper plate and a lower plate that are coaxially arranged and relatively rotatable, and the upper plate and the lower plate are respectively provided with feeding grooves; The driving components include a side rod fixed to the mounting shaft and a push rod fixed to the adjusting plate; When the side rod rotates on the mounting shaft to open the baffle, it can push the lower plate to rotate so that the lower plate and the upper plate's feed chute are misaligned and closed. When the adjustment plate rises to the preset height, the push rod can push the lower plate to rotate so that the lower plate and the upper plate's feeding chute are aligned and opened.

[0008] Preferably, a radial plate and a wedge are fixed to the bottom of the lower plate; When the side rod rotates, it can act on the radial plate to push the lower plate to rotate, so that the sealing assembly closes; When the push rod rises, it acts on the inclined surface of the wedge to push the lower plate to rotate, thereby opening the sealing assembly. In this way, the opening and closing of the sealing assembly can be better adjusted by raising and lowering the adjusting plate, and the powder can be better controlled to be filled into the mixing cylinder at the appropriate time.

[0009] Preferably, the tank body is equipped with a rotating shaft that rotates coaxially inside, and the rotating shaft passes through the hopper and is rotatably connected to it. The top end of the rotating shaft is equipped with a motor installed on the top of the tank body to drive it to rotate inside the tank body. The bracket is located inside the tank body and fixed to the rotating shaft. The bottom end of the mixing cylinder is rotatably mounted on the bracket. The rotating shaft drives the bracket to rotate, which in turn drives the mixing cylinder to revolve within the tank body.

[0010] Preferably, a reciprocating screw is coaxially arranged inside the mixing cylinder, the bottom end of the reciprocating screw is fixedly mounted on the bracket, and a sliding sleeve fixed to the adjusting plate is sleeved on the reciprocating screw; The rotation of the mixing cylinder drives the sliding sleeve to rotate relative to the reciprocating screw, which in turn transforms the sliding sleeve and the adjusting plate into reciprocating lifting motion along the axis of the reciprocating screw.

[0011] Preferably, a movable gear ring is coaxially sleeved on the outside of the mixing cylinder, and a fixed gear ring that meshes with the movable gear ring is coaxially fixed inside the tank body; The mixing cylinder rotates during its revolution by meshing with the fixed gear ring.

[0012] Preferably, the outer part of the hopper is rotatably fitted with a conical outer hopper, and a discharge pipe is inserted into the outer hopper. The top end of the mixing cylinder is rotatably fitted to the bottom end of the discharge pipe.

[0013] Preferably, a filter screen is provided on the side wall of the hopper, and a crushing roller adapted to the filter screen is provided on the rotating shaft. The filter screen can screen out the lumps in the powder, and then the crushing roller can crush them, thereby ensuring that the powder can be better dispersed and quickly integrated with the sewage.

[0014] Preferably, the outer surface of the baffle is provided with stirring blades, which can stir the sewage when the mixing cylinder rotates. The top side wall of the mixing cylinder is provided with a drainage groove, which can discharge the sewage retained in the mixing cylinder when the adjusting plate is raised, so as to facilitate the subsequent filling of the powder into the mixing cylinder.

[0015] Beneficial effects: 1. In use, the powder is released directly from the moving mixing cylinder at the middle depth of the wastewater, rather than being sprinkled from the surface. This immediately places the powder in an environment surrounded by water flow, allowing it to disperse rapidly using fluid shear force. This fundamentally avoids the problems of light powders floating, clumping, and being difficult to dissolve on the surface. Each mixing cylinder acts as a moving point source, constantly changing its dosing position during revolution and rotation, ensuring that the powder is evenly distributed in the three-dimensional space of the tank. This eliminates areas of excessively high or low concentration caused by static dosing, resulting in faster and more thorough mixing.

[0016] 2. When using this invention, an interlocking logic of "closing the filling port first, then opening the release port; closing the release port first, then opening the filling port" is adopted to ensure that when releasing the powder into the sewage, the powder channel above is simultaneously closed by the sealing component, completely eliminating the risk of sewage backflow, blockage of the precision feed pipe and powder hopper.

[0017] 3. When in use, the filter screen and rotating crushing roller integrated in the hopper of this invention can screen and crush the powder agglomerates in real time during the dosing process, ensuring that the powder entering the mixing system is of uniform and fine particle size, further accelerating the dissolution rate and improving the effective utilization rate of the agent.

[0018] 4. When the present invention is in use, the mixing cylinder itself and its baffles and stirring blades form a highly efficient agitator during the revolution and rotation process, so that the mixing and dosing processes are highly overlapped in time and space and mutually promoted, realizing the integrated and efficient operation of "stirring, adding medicine and mixing at the same time", and making fuller use of energy.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 10As shown, the wastewater treatment equipment for cleaning waste incinerator slag of the present invention includes a tank 10, a hopper 20, a rotating frame 30, a mixing cylinder 40, a sealing assembly 50, an adjusting plate 60, a lifting assembly 70, and a transmission assembly 80. The hopper 20 is coaxially arranged inside the tank 10 for temporary storage of the powder. The rotating frame 30 is rotatably arranged inside the tank 10 and can drive the mixing cylinder 40 to rotate and revolve within the tank 10 to agitate the wastewater. The mixing cylinder 40 is arranged between the rotating frame 30 and the hopper 20, and the powder in the hopper 20 can be filled into the mixing cylinder 40. The sealing assembly 50, the adjusting plate 60, and the lifting assembly 70 are all provided with... Inside the mixing cylinder 40, as the mixing cylinder 40 revolves, the transmission component 80 drives it to rotate on the rotating frame 30, which in turn causes the lifting component 70 to drive the adjusting plate 60 to move up and down reciprocally inside the mixing cylinder 40. As the adjusting plate 60 descends, the mixing cylinder 40 opens, allowing the powder to be added directly to the middle of the wastewater in the tank 10. At the same time, the sealing component 50 seals the mixing cylinder 40, stopping the filling of the powder. As the adjusting plate 60 rises, the mixing cylinder 40 closes again, pushing the wastewater retained inside the mixing cylinder 40 to rise and be discharged. When the adjusting plate 60 approaches the top of the mixing cylinder 40, it drives the sealing component 50 to open, continuing the filling of the powder.

[0032] The top of the tank body 10 is respectively connected to the liquid inlet pipe 11 and the feed pipe 12.

[0033] refer to Figure 2 The hopper 20 is conical and connected to the feed pipe 12. A conical outer hopper 21 is rotatably mounted on the outside of the hopper 20. Multiple feed pipes 22 are inserted into the outer hopper 21 and are evenly distributed in a ring for feeding the powder. A push plate 23 is provided inside the outer hopper 21 and is located on one side of the top opening of the feed pipe 22. When the outer hopper 21 rotates on the hopper 20, it can push and intercept the powder in the outer hopper 21 so that the material can enter the interior of the feed pipe 22 better. A filter screen 24 is provided on the box wall of the hopper 20 to filter the powder and ensure that the clumps in the powder do not enter the outer hopper 21 and are added to the tank 10, thereby improving the mixing effect of the powder and the wastewater.

[0034] refer to Figure 2 and Figure 5 The rotating frame 30 includes a rotating shaft 31 and a bracket 32. The rotating shaft 31 is coaxially rotatably mounted inside the tank 10 and passes through the hopper 20 and is rotatably connected to it. A motor is installed at the top of the rotating shaft 31 and mounted on the top of the tank 10 to drive it to rotate inside the tank 10. The bracket 32 ​​is located inside the tank 10 and fixed to the rotating shaft 31, and can rotate inside the tank 10 under the drive of the rotating shaft 31.

[0035] A mounting base 311 is fixedly installed on the rotating shaft 31 inside the feeding hopper 20. A crushing roller 312 adapted to the filter screen 24 is rotatably mounted on the mounting base 311 so that when the rotating shaft 31 rotates, the mounting base 311 can drive the crushing roller 312 to rotate inside the feeding hopper 20, crushing and pulverizing the powder clumps screened in the filter screen 24, so that the pulverized powder can pass through the filter screen 24 and enter the outer hopper 21 to complete the feeding.

[0036] refer to Figure 2 and Figure 5 Multiple mixing cylinders 40 are vertically arranged inside the tank body 10. Each mixing cylinder 40 is rotatably mounted on the bottom end of a plurality of discharge pipes 22. The bottom end of each mixing cylinder 40 is rotatably mounted on a bracket 32, allowing the mixing cylinder 40 to revolve within the tank body 10 as the bracket 32 ​​rotates, thereby agitating the wastewater and accelerating the mixing of the wastewater and the powder. A through groove 41 is provided on each mixing cylinder 40 to allow the mixing cylinder 40 and the tank body 10 to communicate through the through groove 41. The mixing cylinder 40 is connected to the tank 10, allowing the powder in the mixing cylinder 40 to enter the tank 10 and the wastewater in the tank 10 to enter the mixing cylinder 40. The mixing cylinder 40 is vertically rotatably mounted with an installation shaft 42, on which a baffle 43 located inside the through groove 41 is fixedly installed to block the through groove 41, so that the mixing cylinder 40 and the tank 10 cannot communicate, thereby preventing the powder in the mixing cylinder 40 from entering the tank 10 and the wastewater in the tank 10 from entering the mixing cylinder 40.

[0037] refer to Figure 3 , Figure 8 , Figure 9 as well as Figure 10 The sealing assembly 50 includes an upper plate 51 and a lower plate 52. The upper plate 51 is coaxially fixed to the top of the mixing cylinder 40, and the lower plate 52 is coaxially rotatably mounted on the bottom of the upper plate 51. The upper plate 51 and the lower plate 52 are respectively provided with feeding grooves 53. By rotating the lower plate 52 at the bottom of the upper plate 51, the feeding grooves 53 on the upper plate 51 and the lower plate 52 can be aligned and connected, thereby connecting the feeding pipe 22 with the mixing cylinder 40. This allows the powder in the feeding pipe 22 to pass through the feeding grooves 53 and fill the interior of the mixing cylinder 40. Simultaneously, it also allows the upper plate 51 and the lower plate 52 to connect and communicate. The feeding trough 53 on the disc 52 is misaligned, which causes the feeding pipe 22 to no longer connect with the mixing cylinder 40, stopping the filling of powder into the mixing cylinder 40. The top of the upper disc 51 is conical so that the powder can slide down the top surface of the upper disc 51 into the feeding trough 53. Magnets 54 are fixedly installed on both the upper disc 51 and the lower disc 52, and the two magnets 54 attract each other. Through the magnetic attraction of the two magnets 54, the lower disc 52 is attracted to the bottom of the upper disc 51. When the lower disc 52 is not subjected to external pushing force, it can rotate synchronously with the upper disc 51 when the mixing cylinder 40 rotates.

[0038] refer to Figure 4 , Figure 6 as well as Figure 7 The adjusting plate 60 is provided with a sliding groove 61 that is adapted to the mounting shaft 42. The adjusting plate 60 is slidably disposed outside the mounting shaft 42 through the sliding groove 61 with a single degree of freedom. This restricts the adjusting plate 60 to only slide up and down with a single degree of freedom within the mixing cylinder 40 and prevents it from rotating within the mixing cylinder 40. The mounting shaft 42 is provided with a guide groove 421. A protrusion 62 adapted to the guide groove 421 is fixedly installed in the sliding groove 61. The protrusion 62 can slide along the guide groove 421 as the adjusting plate 60 rises and falls, and drive the mounting shaft 42 to rotate during the sliding, so that the baffle 43 can be screwed into or out of the through groove 41, thereby closing or opening the through groove 41.

[0039] refer to Figure 6 The guide groove 421 includes at least one spirally extending inclined groove 4211 and two vertical grooves 4212 respectively connected to both ends of the inclined groove 4211. A protrusion 62 is disposed in the vertical groove 4212 located above the inclined groove 4211. By sliding the protrusion 62 within the vertical groove 4212 above the inclined groove 4211, the mounting shaft 42 can be restricted from rotating, keeping the baffle 43 closed, thus facilitating the filling of the powder into the mixing cylinder 40. When the protrusion 62 enters the inclined groove 4211 from the vertical groove 4212, as the protrusion 62 descends within the inclined groove 4211, it can drive the mounting shaft 42 to rotate, causing the baffle 43 to rotate and open. The lifting within 4211 can drive the mounting shaft 42 to rotate, causing the baffle 43 to rotate and close. When the protrusion 62 enters the lower vertical groove 4212 from the inclined groove 4211, it can again restrict the mounting shaft 42 from rotating, keeping the baffle 43 open. The sewage in the tank 10 can flow into the mixing cylinder 40, carrying out the powder. Then, as the mixing cylinder 40 revolves within the tank 10, the powder is directly added at different positions in the middle of the sewage, allowing the powder to diffuse from the middle of the sewage to the surrounding areas, rather than from the surface of the sewage downwards. This avoids the powder from clumping and floating on the surface, thereby accelerating the diffusion rate of the powder and improving the mixing efficiency of the powder and sewage.

[0040] refer to Figure 6 , Figure 7 , Figure 9 as well as Figure 10 The mounting shaft 42 and the adjusting plate 60 are equipped with driving components, which can drive the lower plate 52 to rotate when the baffle 43 closes the through slot 41, so that the sealing assembly 50 is closed, and can also drive the lower plate 52 to rotate after the adjusting plate 60 is raised to a preset height, so that the sealing assembly 50 is opened.

[0041] The driving component includes a side rod 422 and a push rod 63. The side rod 422 is fixedly mounted on the mounting shaft 42. A radial plate 521 adapted to the side rod 422 is fixedly mounted on the bottom of the lower plate 52. The top end of the side rod 422 extends to the side of the radial plate 521. When the mounting shaft 42 rotates to open the baffle 43, the side rod 422 can push the radial plate 521 to make the lower plate 52 rotate at the bottom of the upper plate 51, causing the lower plate 52 to be misaligned with the feeding chute 53 on the upper plate 51, thus closing the sealing assembly 50 and stopping the powder from flowing into the mixing cylinder 4. The filling of the powder is 0, which allows the filling of the powder to be paused when the powder is mixed with the sewage. The push rod 63 is fixedly installed on the top of the adjusting plate 60, and the bottom of the lower plate 52 is fixedly installed with a wedge 522 located on the side of the radial plate 521. When the adjusting plate 60 is raised, the push rod 63 can push the inclined surface of the wedge 522 to make the lower plate 52 rotate at the bottom of the upper plate 51, thereby aligning the lower plate 52 with the feeding trough 53 on the upper plate 51, opening the sealing assembly 50, and allowing the powder to be filled into the interior of the mixing cylinder 40 through the feeding trough 53 for easy addition of the powder.

[0042] refer to Figure 3 and Figure 4 The lifting assembly 70 includes a reciprocating screw 71 and a sliding sleeve 72. The reciprocating screw 71 is coaxially disposed inside the mixing cylinder 40, and its bottom end is fixedly mounted on the bracket 32. The mixing cylinder 40, the upper plate 51, and the lower plate 52 are all rotatably connected to the reciprocating screw 71. The sliding sleeve 72 is sleeved on the reciprocating screw 71 and fixed to the adjusting plate 60. When the mixing cylinder 40 rotates, it can push the adjusting plate 60 to rotate the sliding sleeve 72 on the reciprocating screw 71. The rotating sliding sleeve 72 is guided by the spiral groove outside the reciprocating screw 71 to move back and forth along its axial direction, thereby causing the sliding sleeve 72 to drive the adjusting plate 60 to rise and fall inside the mixing cylinder 40, thereby controlling the opening of the baffle 43. The mixing cylinder 40 is opened and closed. A drainage groove 45 is provided on the side wall at the top of the mixing cylinder 40. The drainage groove 45 is located above the sewage liquid level in the tank 10. When the adjusting plate 60 is raised, the sewage retained in the mixing cylinder 40 is pushed up and discharged to the outside of the mixing cylinder 40 through the drainage groove 45 to facilitate the subsequent filling of the powder. The top of the reciprocating screw 71 is fixed with a material blocking plate 711 located at the top of the upper plate 51. When the upper plate 51 rotates with the mixing cylinder 40, the material blocking plate 711 blocks the powder above the upper plate 51, so that the powder can fall into the feed trough 53 in the upper plate 51 better and avoid the powder from accumulating above the upper plate 51.

[0043] refer to Figure 2 and Figure 5The transmission assembly 80 includes a moving gear ring 81 and a fixed gear ring 82. The moving gear ring 81 is coaxially fixed to the outside of the mixing cylinder 40, and the fixed gear ring 82 is coaxially fixed to the inside of the tank 10 and meshes with the moving gear ring 81. When the bracket 32 ​​drives the mixing cylinder 40 to revolve within the tank 10, the fixed gear ring 82 can push the moving gear ring 81 to rotate, causing the mixing cylinder 40 to rotate during its revolution. This, in turn, drives the adjusting plate 60 and the sliding sleeve 72 to rotate around the reciprocating screw 71. The outer surface of the baffle 43 is provided with stirring blades 44, which allows the mixing cylinder 40 to stir the wastewater when it rotates on the bracket 32, thus accelerating the mixing of the powder and the wastewater.

[0044] Working principle: The rotating shaft 31 rotates, driving the rotating frame 30 and multiple mixing cylinders 40 to revolve within the tank 10, thus initially agitating the sewage. During the revolve, the moving toothed ring 81 on the outside of the mixing cylinder 40 meshes with the fixed toothed ring 82 fixed on the inner wall of the tank, forcing the mixing cylinder 40 to rotate, and the stirring blades 44 agitate the sewage.

[0045] When the mixing cylinder 40 rotates, it drives the internal sliding sleeve 72 to rotate around the reciprocating screw 71 and begin to rise, thereby pushing the adjusting plate 60 to rise. The push rod 63 at the top of the adjusting plate 60 contacts and pushes the wedge block 522, forcing the lower plate 52 to rotate, so that the upper plate 51 and the feeding trough 53 on the lower plate 52 are aligned and opened. The powder enters the feeding hopper 20 from the feeding pipe 12, and after being filtered by the filter screen 24 and crushed by the crushing roller 312, it fills the interior of the mixing cylinder 40 through the feeding pipe 22 and the opened feeding trough 53.

[0046] After the sliding sleeve 72 moves to the top of the reciprocating screw 71, it begins to drive the adjusting plate 60 to descend. The protrusion 62 on the adjusting plate 60 enters the inclined groove 4211 from the vertical groove 4212 of the guide groove 421, forcing the mounting shaft 42 to rotate, thereby opening the baffle 43. At the same time, the side rod 422 on the mounting shaft 42 pushes the radial plate 521, causing the lower plate 52 to rotate. The upper plate 51 and the feeding groove 53 of the lower plate 52 are misaligned and closed, stopping the filling of the powder. As the baffle 43 opens, the space filled with powder in the mixing cylinder 40 is instantly connected to the external high-pressure sewage. The sewage rushes in at high speed from the through groove of the mixing cylinder 40, carrying out all the powder in the mixing cylinder 40 and releasing it directly at the middle depth of the sewage. At this time, the sealing assembly 50 is closed to prevent sewage from flowing back into the feeding system.

[0047] As the sliding sleeve 72 moves to the bottom of the reciprocating screw 71, it begins to drive the adjusting plate 60 to rise again. The protrusion 62 rises along the inclined groove 4211, driving the mounting shaft 42 to reverse. The baffle 43 gradually closes, re-isolating the inside and outside of the mixing cylinder 40. When the protrusion 62 enters the upper vertical groove 4212, the baffle 43 is completely closed and locked. The adjusting plate 60 continues to rise, pushing the sewage that is stuck in the mixing cylinder 40 upward. The rising sewage is discharged from the drainage groove 45 on the top side of the mixing cylinder 40. When the push rod 63 contacts the wedge block 522 again, a new round of powder filling begins.

[0048] In this invention, the medicinal powder is directly released from the moving mixing cylinder 40 into the middle depth of the wastewater, rather than being sprinkled from the surface. This immediately places the powder in an environment surrounded by water flow, allowing for rapid dispersion using fluid shear force. This fundamentally avoids the problems of light medicinal powders floating, clumping, and being difficult to dissolve on the surface. Each mixing cylinder 40 acts as a moving point source, continuously changing its dosing position during revolution and rotation, ensuring uniform distribution of the powder within the three-dimensional space of the tank. This eliminates areas of excessively high or low concentration caused by static dosing, resulting in faster and more thorough mixing. The interlocking logic of "closing the filling port first, then opening the release port; closing the release port first, then opening the filling port" ensures that when releasing the powder into the wastewater, the upper powder channel is simultaneously closed by the sealing component 50, completely eliminating the risk of wastewater backflow and blockage of the precision feed pipe 22 and the powder hopper. The feed hopper 20 contains... The integrated filter screen 24 and rotating crushing roller 312 can screen and crush powder clumps in real time during the dosing process, ensuring that the powder entering the mixing system is uniform and fine, further accelerating the dissolution rate and improving the effective utilization rate of the agent. The mixing cylinder 40 itself and its baffles 43 and stirring blades 44 form a high-efficiency stirrer during the revolution and rotation, so that the stirring and dosing processes are highly overlapped in time and space and mutually promote each other, realizing the integrated and efficient operation of "stirring, adding, and mixing at the same time", and making fuller use of energy. The driving force of the entire dosing cycle (filling, releasing, cleaning) comes entirely from the stirring motion driven by the main motor of the equipment. There is no need to configure an additional independent motor, cylinder or complex electrical control system to control the dosing valve. The equipment can add drugs when it is running and stop drugs when it stops. It has a high degree of automation and has advantages in cost and reliability.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
