Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, specifically to a dosing device for wastewater treatment in environmental engineering. Background Technology

[0002] Environmental engineering is the science and technology that studies and engages in the prevention and control of environmental pollution and the improvement of environmental quality. Its core is the treatment and control of environmental pollution sources, among which wastewater treatment is one of the important treatment components of environmental engineering.

[0003] A search revealed a wastewater treatment dosing device disclosed in Chinese Patent Publication No. CN221166023U. The key technical point of this device is that it solves the problems of wastewater treatment requiring the use of multiple chemical agents, the need to wait until the dosing port is fully open before adding the agents, the risk of inhaling harmful gases during manual dosing, the accumulation of chemicals in one place due to the dosing port, the inability to fully mix with the wastewater, the limited practicality of the device, and the cumbersome operation.

[0004] However, it has been found in the above-mentioned schemes and existing technologies that, when adding chemicals, the dosage of chemicals in wastewater treatment is subject to specific indicators, and neither the above-mentioned schemes nor existing devices can achieve quantitative dosing. Excessive addition of chemicals will lead to an increase in sludge in the treatment system, affecting the treatment capacity of the sludge dewatering system, and even resulting in poor treatment effect. Insufficient addition will lead to unsatisfactory treatment effect and failure to achieve the expected purification effect. In order to solve the problem of the inability to achieve quantitative dosing of chemicals in the existing technology, which easily leads to too much or too little chemical addition, this application proposes to set up telescopic rod one and telescopic rod two, so that by raising and lowering the cylinder and the piston block, a certain amount of chemical can be extracted and finally discharged into the wastewater, so as to achieve the effect of quantitative chemical addition of this device and prevent the chemical addition from affecting wastewater treatment due to too much or too little chemical addition. Therefore, a new scheme is needed to solve this problem. Utility Model Content

[0005] The existing technologies mentioned above have shortcomings and defects in achieving quantitative dosing of chemicals, which can easily lead to excessive or insufficient dosage of chemicals, thus affecting wastewater treatment.

[0006] This utility model discloses a wastewater treatment dosing device for environmental engineering, comprising a container cylinder, a telescopic rod fixedly connected to the inner wall of the container cylinder, a connecting frame fixedly connected to the output end of the telescopic rod, two cylinders fixedly connected to the bottom surface of the connecting frame, the outer surface of each cylinder being slidably connected to the inner wall of the container cylinder, and each cylinder having two equally spaced circular holes (a first and a second) on its outer surface, a telescopic rod (b) fixedly connected to the front of the container cylinder, a piston block fixedly connected to the output end of the telescopic rod (b), a connecting cylinder slidably connected to the outer surface of the piston block, and injection cylinders fixedly connected to the left and right ends of the connecting cylinder, with the inner wall of each injection cylinder slidably connected to the outer surface of the corresponding cylinder.

[0007] Furthermore, a mounting bracket is fixedly connected to the bottom surface of the container, and the outer surface of each injection cylinder is fixedly connected to the inner wall of the mounting bracket.

[0008] Furthermore, a motor is fixedly connected to the upper surface of the mounting frame, and a processing bucket is fixedly connected to the outer surface of the mounting frame.

[0009] Furthermore, the output shaft of the motor is fixedly connected to a first conical wheel, and a second conical wheel meshes with the outer surface of the first conical wheel.

[0010] Furthermore, a rotating rod is fixedly connected to the inner wall of the second conical wheel, and a gear is fixedly connected to the outer surface of the rotating rod.

[0011] Furthermore, two gears are engaged on the outer surface of the first gear, and a connecting rod is fixedly connected to the inner wall of each gear.

[0012] Furthermore, the outer surface of each connecting rod is rotatably connected to the inner wall of the mounting frame, and the outer surface of each connecting rod is fixedly connected with stirring rods arranged at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a telescopic rod, a connecting frame, a cylinder, a piston block, a connecting tube, and an injection tube, allows for the addition of medicine when necessary. When medicine needs to be added, the telescopic rod 1 drives the connecting frame and the cylinder to descend. At this time, the first and second round holes descend, and the medicine inside the container enters the cylinder through the first round hole. The second round hole then aligns with the connecting tube. The telescopic rod 2 is activated, allowing the piston block to rise inside the connecting tube and extract the medicine from the cylinder through the second round hole. After extracting a certain amount, the telescopic rod 1 returns the cylinder to its original position. At this time, the outlet of the connecting tube connects with the injection tube. The extension of the telescopic rod 2 causes the piston block to descend, pushing out the medicine, which is then discharged into the wastewater through the injection tube. This device enables medicine to be added from both sides, and the extension and retraction of the telescopic rod 2 achieves the effect of quantitative medicine dosing.

[0015] 2. This utility model comprises components such as a conical wheel 1, a conical wheel 2, a gear 1, a gear 2, a connecting rod, and a stirring rod. A motor drives the conical wheel 1 to rotate. The connection between the conical wheel 1 and the conical wheel 2 enables the conical wheel 2 to rotate. The conical wheel 2 drives the rotating rod to rotate, which in turn causes the gear 1 to rotate. The connection between the gear 1 and the gear 2 allows the two gears 2 to rotate synchronously, thereby causing the two connecting rods to rotate. The connecting rods then drive the surface-mounted stirring rod, enabling the stirring rod to agitate the wastewater inside the treatment tank. This allows the device to effectively mix the added chemicals with the wastewater, improving wastewater treatment efficiency. Attached Figure Description

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model discloses a wastewater treatment dosing device for environmental engineering, comprising a container cylinder 1, with a telescopic rod 2 fixedly connected to the inner wall of the container cylinder 1. The telescopic rod 2 is installed on the inner wall of the container cylinder 1 for fixed connection, achieving the positioning effect of the telescopic rod 2. A connecting frame 3 is fixedly connected to the output end of the telescopic rod 2 for fixed connection. The connecting frame 3 is raised and lowered by extending and shortening the telescopic rod 2. Two cylinders 4 are fixedly connected to the bottom surface of the connecting frame 3 for installation. The cylinders 4 are raised and lowered by raising and lowering the connecting frame 3, thereby achieving the raising and lowering effect of the cylinders 4.

[0024] In a preferred embodiment, the outer surface of each cylinder 4 is slidably connected to the inner wall of the container 1. The cylinder 4 is installed on the inner wall of the container 1 and is set as a sliding connection to limit the position of the cylinder 4. A sealing ring is set between the container 1 and the cylinder 4 to prevent leakage. The outer surface of each cylinder 4 is provided with equally spaced circular holes 5 and 6. The circular holes 5 and 6 are opened on the surface of the cylinder 4. The circular holes 5 facilitate the flow of medicine into the interior of the cylinder 4, and the circular holes 6 facilitate the flow of medicine out of the interior of the cylinder 4.

[0025] like Figure 4 As shown, a telescopic rod 2 7 is fixedly connected to the front of the container 1. The telescopic rod 2 7 is installed on the front of the container 1 to achieve the positioning and installation effect of the telescopic rod 2 7. Both the telescopic rod 1 2 and the telescopic rod 2 7 are electric telescopic rods. A piston block 8 is fixedly connected to the output end of the telescopic rod 2 7. The piston block 8 is installed on the output end of the telescopic rod 2 7 to achieve the installation of the piston block 8. The piston block 8 is raised and lowered by the telescopic rod 2 7. A connecting cylinder 9 is slidably connected to the outer surface of the piston block 8. The connecting cylinder 9 is installed on the surface of the piston block 8, and the connecting cylinder 9 and the piston block 8 are set as a sliding connection. By raising and lowering the piston block 8, the pressure inside the connecting cylinder 9 is changed, which makes it easier to draw the medicine into the interior of the connecting cylinder 9 through the round hole 2 6.

[0026] In this embodiment, the left and right ends of the connecting cylinder 9 are fixedly connected to the injection cylinder 10. The injection cylinder 10 is installed on the left and right ends of the connecting cylinder 9 and is set to be connected. When the piston block 8 descends, it is convenient to push the liquid medicine inside the connecting cylinder 9 into the inside of the injection cylinder 10 and finally fall into the sewage below. The inner wall of each injection cylinder 10 is slidably connected to the outer surface of the corresponding cylinder 4. The cylinder 4 is connected to the injection cylinder 10. The lifting and lowering of the cylinder 4 is convenient to connect the second hole 6 to the connecting cylinder 9.

[0027] Combination Figure 1 and Figure 3A mounting bracket 11 is fixedly connected to the bottom surface of the container 1. The mounting bracket 11 is installed on the bottom surface of the container 1 to support the container 1. The outer surface of each injection cylinder 10 is fixedly connected to the inner wall of the mounting bracket 11. The mounting bracket 11 is connected to the injection cylinder 10 to form a fixed connection, thereby limiting the position of the injection cylinder 10.

[0028] In a preferred embodiment, a motor 12 is fixedly connected to the upper surface of the mounting frame 11, and the motor 12 is installed on the upper surface of the mounting frame 11 to realize the installation of the motor 12. A treatment tank 20 is fixedly connected to the outer surface of the mounting frame 11, and the treatment tank 20 is installed on the surface of the mounting frame 11. The treatment tank 20 is used to hold sewage, and the mounting frame 11 provides support for the treatment tank 20.

[0029] In this embodiment, a conical wheel 13 is fixedly connected to the output shaft of the motor 12. The conical wheel 13 is mounted on the output shaft of the motor 12 and is fixedly connected. The motor 12 facilitates the rotation of the conical wheel 13. A conical wheel 14 meshes with the outer surface of the conical wheel 13. The conical wheel 14 is placed above the conical wheel 13 and the conical wheel 13 and the conical wheel 14 are connected. The rotation of the conical wheel 13 can realize the rotation of the conical wheel 14.

[0030] Looking back Figure 3 A rotating rod 15 is fixedly connected to the inner wall of the second conical wheel 14. The rotating rod 15 is installed on the inner wall of the second conical wheel 14 and is set as a fixed connection. When the second conical wheel 14 rotates, the rotating rod 15 can rotate. The rotating rod 15 is rotatably connected to the mounting bracket 11 to achieve the limiting effect of the rotating rod 15. A gear 16 is fixedly connected to the outer surface of the rotating rod 15. The gear 16 is installed on the outer surface of the rotating rod 15. When the rotating rod 15 rotates, the gear 16 can rotate.

[0031] In a preferred embodiment, two gears 17 mesh with the outer surface of gear 16. Gears 17 are mounted on the side of gear 16, and two gears 17 are provided. Gear 16 and gears 17 are connected. When gear 16 rotates, the two gears 17 rotate synchronously. A connecting rod 18 is fixedly connected to the inner wall of each gear 17. The connecting rod 18 is mounted on the inner wall of the corresponding gear 17 and is fixedly connected to achieve the rotation effect of the connecting rod 18.

[0032] In this embodiment, the outer surface of each connecting rod 18 is rotatably connected to the inner wall of the mounting frame 11. The outer surface of the connecting rod 18 is connected to the mounting frame 11 in a rotatable manner. The mounting frame 11 achieves the limiting effect of the connecting rod 18. Each connecting rod 18 has a stirring rod 19 fixedly connected to its outer surface at equal intervals. The stirring rod 19 is installed on the surface of the corresponding connecting rod 18 in a fixed manner. When the connecting rod 18 rotates, the stirring rod 19 can rotate. The stirring rod 19 can stir the sewage, prevent sewage sedimentation, and facilitate the full mixing of the agent and the sewage.

[0033] The implementation principle is as follows: A motor 12 drives a conical wheel 13 to rotate. The connection between conical wheel 13 and conical wheel 14 enables the rotation of conical wheel 14. Conical wheel 14 drives a rotating rod 15 to rotate, which in turn causes gear 16 to rotate. Gear 16 then causes two gears 17 to rotate synchronously, which in turn causes two connecting rods 18 to rotate. Connecting rods 18 drive surface-mounted stirring rods 19, which agitate the wastewater inside the treatment tank 20 to prevent sedimentation. When chemical addition is needed, telescopic rod 2 descends, causing connecting frame 3 and cylinder 4 to descend. At this time, circular holes 5 and 6 are closed. As the second hole 6 descends, the first hole 5 allows the medicine inside the first cylinder to enter the second cylinder 4. At this time, the second hole 6 corresponds to the connecting cylinder 9. The second telescopic rod 7 is activated, allowing the piston block 8 to rise inside the connecting cylinder 9. The medicine inside the second cylinder 4 can be easily extracted through the second hole 6. After a certain dose is extracted, the telescopic rod 2 resets the second cylinder 4. At this time, the outlet of the connecting cylinder 9 is connected to the injection cylinder 10. The extension of the second telescopic rod 7 causes the piston block 8 to descend, pushing out the medicine. Then, the medicine is discharged into the sewage through the injection cylinder 10. The extension and retraction of the second telescopic rod 7 achieves quantitative drug dosing. The stirring rod 19 ensures that the medicine and sewage are fully mixed.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
