Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a carbon source dosing device for treating kitchen wastewater. Background Technology

[0002] Carbon sources are essential nutrients for microbial growth. By adding an appropriate amount of carbon source to kitchen wastewater, the growth and metabolic activity of microorganisms can be promoted, thereby accelerating the degradation of organic matter and improving the efficiency of kitchen wastewater treatment.

[0003] A search revealed a Chinese patent with publication number CN222556697U, which discloses a precise carbon source dosing device for wastewater treatment. This patent uses two stirring vortices to increase the mixing speed and prevent the carbon source from clumping together. However, when adding the carbon source to the wastewater tank, the dosing device remains fixed and can only be used to add the carbon source to a single point in the wastewater tank. This is not only inefficient but also prone to causing uneven mixing of the wastewater, resulting in poor wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing dosing devices being fixed and only able to dosing at a single point in the sewage tank, which is not only inefficient but also prone to causing uneven mixing of sewage, resulting in poor sewage treatment effect. Therefore, a carbon source dosing device for kitchen wastewater treatment is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carbon source dosing device for kitchen wastewater treatment includes a mixing tank and a transport trolley. The mixing tank is mounted on top of the transport trolley. A mounting plate is fixedly connected to one outer wall of the mixing tank. A swing voice coil motor is fixedly connected to the top of the mounting plate. A mounting frame is fixedly connected to the output end of the swing voice coil motor. A first motor is fixedly connected inside the mounting frame. A telescopic component is provided at the output end of the first motor. The telescopic component includes multiple first rotating arms, a first connecting rod, a connecting plate, a second rotating arm, and a second connecting rod. One end of the output shaft of the first motor protrudes from the mounting frame and is fixed to one of the first rotating arms. One end of the first connecting rod is rotatably mounted on the outer wall of the mounting frame. The first rotating arm, the first connecting rod, the second rotating arm, and the second connecting rod are respectively fixed to both sides of the connecting plate. A first gear and a second gear are fixedly connected to the first rotating arm and the second rotating arm, respectively. Multiple fixing buckles are fixedly connected to one side of the first rotating arm and one side of the second rotating arm. The multiple fixing buckles are connected to the same delivery hose. Multiple nozzles are inserted into the bottom of the delivery hose.

[0007] Furthermore, a metering pump is fixedly connected to the top of the transport trolley, with the inlet end of the metering pump connected to the mixing tank and the outlet end of the metering pump connected to one end of the delivery hose.

[0008] Furthermore, the bottom of the mounting bracket is fixedly connected to a guide wheel, and the top of the mounting plate is provided with a guide groove, in which the guide wheel rolls.

[0009] Furthermore, the connecting plate has a Z-shaped structure.

[0010] Furthermore, two stirring rods are rotatably inserted into the top inner wall of the mixing tank, and stirring blades are fixedly connected to the outer wall of the stirring rods, with the stirring blades located inside the mixing tank.

[0011] Furthermore, the top of the stirring rod is keyed to a pulley through the top of the mixing tank, and the two pulleys are connected by a belt.

[0012] Furthermore, a support frame is fixedly connected to the top outer wall of the mixing tank, and a second motor is fixedly connected to the top of the support frame. The output end of the second motor is fixedly connected to the top of one of the stirring rods.

[0013] Furthermore, a feed pipe is fixedly connected to the top of the mixing tank.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Driven by the first motor and engaged by the first and second gears, multiple first rotating arms and multiple second rotating arms extend above the sewage tank, thereby loosening the delivery hose and nozzle above the sewage tank for multi-point delivery, thus facilitating subsequent sewage treatment.

[0016] 2. By swinging the telescopic components, delivery hoses, and nozzles horizontally above the sewage tank under the drive of the oscillating voice coil motor, the carbon source is delivered more evenly, thus improving the treatment effect.

[0017] 3. Driven by the second motor and the belt, the stirring rod rotates synchronously, thereby causing the stirring blades to rotate and generating two stirring vortices. This increases the mixing speed, prevents carbon source from clumping, and ensures the wastewater treatment effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 A carbon source dosing device for kitchen wastewater treatment includes a mixing tank 1 and a transport trolley 24. The mixing tank 1 is set on the top of the transport trolley 24. An installation plate 2 is welded to one side of the outer wall of the mixing tank 1. A swing voice coil motor 3 is fixed to the top of the installation plate 2 by bolts. The swing voice coil motor 3 is model TMER0150-030-000. An installation frame 4 is fixed to the output end of the swing voice coil motor 3 by bolts. A first motor 8 is fixed to the installation frame 4 by bolts. The output end of the first motor 8 is provided with a telescopic component. Under the drive of the swing voice coil motor 3, the telescopic component, the conveying hose 17, and the nozzle 18 swing horizontally above the wastewater tank, thereby making the carbon source dosing more uniform.

[0027] The telescopic assembly includes multiple first rotating arms 9, first connecting rods 14, connecting plates 13, second rotating arms 11, and second connecting rods 15;

[0028] like Figure 4 and Figure 5As shown, one end of the output shaft of the first motor 8 protrudes from the mounting bracket 4 and is fixed to a first rotating arm 9. One end of a first connecting rod 14 is rotatably mounted on the outer wall of the mounting bracket 4. The other ends of the first rotating arm 9 and the first connecting rod 14 are rotatably connected to the same connecting plate 13, wherein the connecting plate 13 has a Z-shaped structure.

[0029] One end of the connecting plate 13 is rotatably connected to the second rotating arm 11 and the second connecting rod 15. The first rotating arm 9 and the second rotating arm 11 are respectively fixedly connected to the first gear 10 and the second gear 12. The first gear 10 meshes with the second gear 12. The other end of the second rotating arm 11 and the second connecting rod 15 is rotatably connected to another adjacent connecting plate 13.

[0030] Multiple first rotating arms 9, second rotating arms 11, connecting plate 13, first connecting rod 14 and second connecting rod 15 are installed in the manner described above. When in operation, driven by the first motor 8, the first rotating arms 9 and the first connecting rod 14 rotate. Under the action of the meshing of the first gear 10 and the second gear 12, multiple first rotating arms 9 and multiple second rotating arms 11 extend to the top of the sewage tank.

[0031] Multiple fixing buckles 16 are bolted to one side of the first rotating arm 9 and one side of the second rotating arm 11. The same delivery hose 17 is snapped between the multiple fixing buckles 16. Multiple nozzles 18 are inserted into the bottom of the delivery hose 17. A metering pump 5 is bolted to the top of the transport trolley 24. The inlet end of the metering pump 5 is connected to the mixing tank 1, and the outlet end of the metering pump 5 is connected to one end of the delivery hose 17. Under the suction of the metering pump 5, the carbon source in the mixing tank 1 is input into the delivery hose 17, and then sprayed from the nozzles 18 into the sewage in the sewage tank, thereby adding the carbon source into the sewage tank.

[0032] The bottom of the mounting frame 4 is fixed with guide wheels 6 by bolts, and the top of the mounting plate 2 is provided with guide grooves 7. The guide wheels 6 roll in the guide grooves 7, thereby providing support for the movement of the mounting frame 4.

[0033] Two stirring rods 19 are rotatably inserted into the inner top wall of the mixing tank 1. Stirring blades 20 are fixed to the outer wall of the stirring rods 19 by bolts. The stirring blades 20 are located inside the mixing tank 1. The top of the stirring rods 19 passes through the top of the mixing tank 1 and is connected to a pulley 21. The two pulleys 21 are connected to a belt 22 for transmission. A support frame is fixed to the outer top wall of the mixing tank 1 by bolts. A second motor 23 is fixed to the top of the support frame by bolts. The output end of the second motor 23 is fixedly connected to the top of one of the stirring rods 19. Driven by the second motor 23 and driven by the belt 22, the stirring rods 19 rotate synchronously, thereby driving the stirring blades 20 to rotate and generate two stirring vortices, which improves the mixing speed. A feed pipe is welded to the top of the mixing tank 1 so that the carbon source can be put into the mixing tank 1 through the feed pipe.

[0034] The working principle of this embodiment is as follows: When in use, firstly, the carbon source is put into the mixing tank 1 through the feed pipe. Then, the second motor 23 is started. Under the drive of the second motor 23 and the transmission action of the belt 22, the stirring rod 19 is driven to rotate synchronously, thereby driving the stirring blade 20 to rotate and generating two stirring vortices, which improves the stirring and mixing speed.

[0035] Then, the mixing tank 1 is moved to the sewage tank where the carbon source needs to be added using the transport trolley 24. Next, the first motor 8 is started. Driven by the first motor 8, multiple first rotating arms 9 and multiple second rotating arms 11 extend to the top of the sewage tank, thereby loosening the delivery hose 17 and the nozzle 18 above the sewage tank. Then, the metering pump 5 is started. Under the suction of the metering pump 5, the carbon source in the mixing tank 1 is input into the delivery hose 17 and then sprayed from the nozzle 18 into the sewage tank, thereby adding the carbon source into the sewage tank.

[0036] During the carbon source delivery process, the swing voice coil motor 3 is started. Driven by the swing voice coil motor 3, the telescopic component, the delivery hose 17, and the nozzle 18 swing horizontally above the sewage tank, thereby making the carbon source delivery more uniform.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
