During the sludge cleaning process, adding specific agents can effectively improve the dewatering performance of sludge, stabilize heavy metals, and kill pathogens. This is a key step in the reduction, harmlessness and resource utilization of sludge. Some sludge treatment projects require precise testing of agent addition to determine the optimal dosage and ratio. Therefore, portable dosing testing devices are indispensable.
[0003] However, existing portable dosing devices generally have some problems: 1. They rely on external power sources, have high energy consumption, complex structures and are prone to failure, making it difficult to work stably in an environment without electricity, and the accuracy of the reagent delivery rate adjustment is insufficient, which cannot meet the diverse sludge testing needs; 2. The devices have poor adaptability and are difficult to be compatible with different specifications of sewage storage tanks.
[0004] Therefore, there is an urgent need for a portable automatic dosing device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a portable automatic dosing device to solve the problems mentioned in the background art.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A clamping assembly includes symmetrically formed grooves on the outer wall of a base frame. A slider is slidably connected to the inner wall of the groove. A mounting plate is fixedly connected to the top wall of the slider. An arc-shaped plate is fixedly connected to the outer wall of the mounting plate. Uniformly distributed anti-slip extrusion blocks are fixedly connected to the outer wall of the arc-shaped plate. Symmetrically distributed bidirectional screws are threaded to the outer wall of the mounting plate, and the bidirectional screws are rotatably connected to the base frame. A drive disk is fixedly connected to the outer wall of the bidirectional screws, and a drive handle is fixedly connected to the outer wall of the drive disk.
[0009] The non-powered drug delivery assembly is located on the outer wall of the base frame.
[0010] As a preferred technical solution of this application, the non-powered drug delivery assembly includes a mounting frame fixedly connected to the outer wall of the base frame. An adjusting screw is threadedly connected to the outer wall of the mounting frame. A knob is fixedly connected to the outer wall of the adjusting screw. A medicine tank is rotatably connected to the top wall of the adjusting screw. A movable U-shaped tube is fixedly connected to the outer wall of the medicine tank. A drug dosing funnel is fixedly connected to the outer wall of the movable U-shaped tube. Both the drug dosing funnel and the top wall of the medicine tank have through holes. A sealing cap is threadedly connected to the outer wall of the drug dosing funnel. A fixed vertical tube is slidably connected to the outer wall of the movable U-shaped tube. A sewage storage tank is fixedly connected to the outer wall of the fixed vertical tube.
[0011] As a preferred technical solution of this application, a ball valve is fixedly connected to the outer wall of the fixed vertical pipe, an adjusting rod is rotatably connected to the outer wall of the ball valve, an adjusting disc is fixedly connected to the outer wall of the adjusting rod, a valve plate is fixedly connected to the end of the adjusting rod away from the adjusting disc, and the valve plate is located on the inner wall of the ball valve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In the scheme of this application:
[0016] 1. By setting up a high-low difference drug delivery channel formed by a movable U-shaped tube and a fixed vertical tube, a siphon structure is formed to realize the automatic delivery of the agent using the siphon principle. This reduces the dependence on energy, saves operating costs, reduces the complexity of the equipment, reduces the probability of equipment failure, improves the reliability and service life of the device, and reduces maintenance costs and workload. In addition, by adjusting the height of the drug tank and the movable U-shaped tube by adjusting the screw, the height difference between the movable U-shaped tube and the fixed vertical tube is changed, thereby adjusting the pressure difference generated by the siphon, that is, realizing the flow rate of the agent per unit time. In conjunction with the opening and closing degree of the valve plate, the flow area of the fixed vertical tube is controlled, thereby ensuring the stability and accuracy of the agent delivery. This solves the problems of existing technologies that rely on external power sources, have high energy consumption, complex structure and easy failure, are difficult to work stably in an environment without electricity, and have insufficient precision in adjusting the agent delivery volume, which cannot meet the diverse sludge testing needs.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0026] like Figure 1-5 As shown, the portable automatic dosing device proposed in this embodiment includes a base frame 1, with symmetrically distributed handlebars 30 fixedly connected to the outer wall of the base frame 1, and further includes:
[0027] The clamping assembly includes symmetrically formed grooves 2 on the outer wall of the base frame 1. A slider 5 is slidably connected to the inner wall of the grooves 2. A mounting plate 6 is fixedly connected to the top wall of the slider 5. An arc-shaped plate 7 is fixedly connected to the outer wall of the mounting plate 6. Uniformly distributed anti-slip compression blocks 8 are fixedly connected to the outer wall of the arc-shaped plate 7. Symmetrically distributed bidirectional screws 9 are threadedly connected to the outer wall of the mounting plate 6, and the bidirectional screws 9 are rotatably connected to the base frame 1. A drive disc 14 is fixedly connected to the outer wall of the bidirectional screws 9, and a drive handle 15 is fixedly connected to the outer wall of the drive disc 14. When it is necessary to fix the sewage storage tank 16, the operator holds the drive handle 15 and rotates it. The drive handle 15 drives the drive disc 14 to rotate synchronously. The rotation of the drive disc 14 causes the bidirectional screws 9 to rotate on the base frame 1. The rod 9 is connected to the mounting plate 6 by a thread. According to the principle of thread transmission, the rotation of the bidirectional screw 9 will be converted into the linear motion of the mounting plate 6. Under the action of the symmetrically distributed bidirectional screw 9, the sliders 5 on both sides will slide towards or away from each other in the groove 2. The sliders 5 drive the mounting plate 6 to move, thereby making the arc plate 7 and the anti-slip extrusion block 8 on the mounting plate 6 move closer or further away. After the sewage storage tank 16 is placed between the arc plates 7, the drive handle 15 is rotated to make the arc plate 7 move closer to the sewage storage tank 16. The anti-slip extrusion block 8 is tightly attached to the surface of the sewage storage tank 16. The anti-slip texture on its surface increases the friction with the sewage storage tank 16, thereby firmly fixing sewage storage tanks 16 of different diameters. It is suitable for sewage storage tanks 16 of various specifications and meets the needs of different usage scenarios.
[0028] The non-powered drug delivery assembly is located on the outer wall of the base frame 1.
[0029] like Figure 4As shown, in a preferred embodiment, based on the above method, the non-powered drug delivery assembly further includes a mounting frame 17 fixedly connected to the outer wall of the base frame 1. An adjusting screw 19 is threadedly connected to the outer wall of the mounting frame 17. A knob 18 is fixedly connected to the outer wall of the adjusting screw 19. A medicine tank 20 is rotatably connected to the top wall of the adjusting screw 19. A movable U-shaped tube 22 is fixedly connected to the outer wall of the medicine tank 20. A drug addition funnel 24 is fixedly connected to the outer wall of the movable U-shaped tube 22. Both the drug addition funnel 24 and the top wall of the medicine tank 20 have through holes 21. A sealing cap 25 is threadedly connected to the outer wall of the drug addition funnel 24. A fixed vertical tube 23 is slidably connected to the outer wall of the movable U-shaped tube 22. A wastewater storage tank 16 is fixedly connected to the outer wall of the fixed vertical tube 23. Before starting drug addition, the adjusting disc 28 is rotated. The adjusting disc 28 drives the adjusting rod 27 to rotate, which in turn drives the valve plate 29 to rotate within the ball valve 26, thus opening the valve... When plate 29 is adjusted to the closed state, the channel of fixed vertical pipe 23 is cut off. Then, the sealing cover 25 on the dosing funnel 24 is opened, and the agent is added from the dosing funnel 24 into the moving U-shaped pipe 22, fixed vertical pipe 23 and the medicine tank 20. Because the medicine tank 20 is connected to the dosing funnel 24 and the moving U-shaped pipe 22 through the through hole 21, the agent can smoothly fill the entire pipeline system. After the agent is added, the adjusting plate 28 is rotated again to open the valve plate 29. At this time, the moving U-shaped pipe 22 and the fixed vertical pipe 23 form a siphon structure. The agent in the fixed vertical pipe 23 flows downward under the action of gravity, causing the air in the pipeline to be discharged and forming a negative pressure area. Under the action of external atmospheric pressure, the agent in the medicine tank 20 enters the moving U-shaped pipe 22 through the through hole 21, continuously replenishing the agent flowing out of the fixed vertical pipe 23, maintaining the continuity of the siphon circuit, thereby realizing the automatic delivery of the agent without power.
[0030] like Figure 5As shown, in a preferred embodiment, based on the above method, a ball valve 26 is fixedly connected to the outer wall of the fixed vertical pipe 23. An adjusting rod 27 is rotatably connected to the outer wall of the ball valve 26. An adjusting disc 28 is fixedly connected to the outer wall of the adjusting rod 27. A valve plate 29 is fixedly connected to the end of the adjusting rod 27 away from the adjusting disc 28, and the valve plate 29 is located on the inner wall of the ball valve 26. The control of the drug output and water pressure is mainly achieved through two means. On the one hand, rotating the knob 18 causes the adjusting screw 19 to rotate on the mounting bracket 17. Since the top wall of the adjusting screw 19 is rotatably connected to the medicine tank 20, the rotation of the adjusting screw 19 will cause the medicine tank 20 to move up and down. The medicine tank 20 drives the moving U-shaped pipe 22 to rise and fall synchronously. According to the siphon principle, the moving U-shaped pipe 22... The height difference between the duct 22 and the fixed vertical pipe 23 affects the pressure difference generated by the siphon. The greater the height difference, the greater the pressure difference, and the greater the flow rate of the agent per unit time. Conversely, the smaller the height difference, the smaller the flow rate, thus regulating the output of the agent per unit time. On the other hand, by rotating the regulating disc 28, the regulating rod 27 and the valve plate 29 are rotated within the ball valve 26, changing the opening and closing degree of the valve plate 29, thereby controlling the flow area of the fixed vertical pipe 23. The smaller the flow area, the greater the resistance to the agent and the less the agent is output. The larger the flow area, the more the agent is output. In this way, the output of the agent can be further precisely controlled, and the water pressure in the pipeline can also be indirectly affected to ensure the stability and accuracy of the agent delivery.
[0031] like Figure 3 As shown, in a preferred embodiment, based on the above method, the base frame 1 is further provided with symmetrically distributed fixing blocks 10 fixedly connected to its outer wall. A guide rod 11 is slidably connected to the outer wall of the fixing blocks 10. A lifting seat 13 is fixedly connected to the top wall of the guide rod 11. A strong spring 12 is sleeved on the outer wall of the guide rod 11, and the strong spring 12 is fixedly connected to the fixing blocks 10 and the lifting seat 13. When the sewage storage tank 16 is installed, it is placed on the lifting seat 13. At this time, it is easy for the base frame 1 to shake and impact, causing noise damage to the sewage storage tank 16 or the base frame 1. The lifting seat 13 compresses the strong spring 12, and the strong spring 12 converts the impact force into its own elastic potential energy. When the impact force disappears, the strong spring 12 releases its elastic potential energy, pushing the lifting seat 13 to reset, effectively absorbing the impact during the installation of the sewage storage tank 16.
[0032] like Figure 1 As shown, in a preferred embodiment, based on the above method, the base frame 1 is further provided with symmetrically distributed support blocks 3 fixedly connected to the outer wall, and the support blocks 3 are fixedly connected with casters 4. The equipment can be moved by the casters 4, making it easy to carry to the required scenario for use.
[0033] Specifically, when using this portable automatic dosing device: when it is necessary to fix the sewage storage tank 16, the operator holds the drive handle 15 and rotates it. The drive handle 15 drives the drive disc 14 to rotate synchronously. The rotation of the drive disc 14 causes the bidirectional screw 9 to rotate on the base frame 1. Since the bidirectional screw 9 is connected to the mounting plate 6 by threads, according to the principle of thread transmission, the rotation of the bidirectional screw 9 will be converted into the linear motion of the mounting plate 6. Under the action of the symmetrically distributed bidirectional screws 9, the sliders 5 on both sides will slide towards or away from each other in the slide groove 2. The sliders 5 drive the mounting plate 6 to move, thereby causing the arc plate 7 and the anti-slip pressing block 8 on the mounting plate 6 to move closer or further away. When the sewage storage tank 16 After being placed between the arc-shaped plates 7, the drive handle 15 is rotated to bring the arc-shaped plates 7 closer to the sewage storage tank 16. The anti-slip compression block 8 fits tightly against the surface of the sewage storage tank 16, and its anti-slip texture increases the friction with the sewage storage tank 16, thereby firmly fixing sewage storage tanks 16 of different diameters. This method is suitable for sewage storage tanks 16 of various specifications and meets the needs of different usage scenarios. Before starting the dosing, the adjusting disc 28 is rotated. The adjusting disc 28 drives the adjusting rod 27 to rotate, which in turn drives the valve plate 29 to rotate inside the ball valve 26. The valve plate 29 is adjusted to the closed state, cutting off the channel of the fixed vertical pipe 23. Then, the sealing cover 25 on the dosing funnel 24 is opened, and the dosing funnel... The funnel 24 adds medicine to the movable U-shaped tube 22, the fixed vertical tube 23, and the medicine tank 20. Because the medicine tank 20 is connected to the funnel 24 and the movable U-shaped tube 22 through the through hole 21, the medicine can smoothly fill the entire pipeline system. After the medicine is added, the adjusting disc 28 is rotated again to open the valve plate 29. At this time, the movable U-shaped tube 22 and the fixed vertical tube 23 form a siphon structure. The medicine in the fixed vertical tube 23 flows downward under the action of gravity, causing the air in the pipeline to be expelled and forming a negative pressure area. Under the action of external atmospheric pressure, the medicine in the medicine tank 20 enters the movable U-shaped tube 22 through the through hole 21, continuously replenishing the medicine flowing out of the fixed vertical tube 23 and maintaining the continuity of the siphon circuit. The continuous operation enables automatic, non-powered delivery of the medicine. The control of the output and water pressure is achieved through two main methods. First, rotating the knob 18 causes the adjusting screw 19 to rotate on the mounting bracket 17. Since the top wall of the adjusting screw 19 is rotatably connected to the medicine tank 20, the rotation of the adjusting screw 19 will cause the medicine tank 20 to move up and down. The medicine tank 20 drives the moving U-shaped tube 22 to rise and fall synchronously. According to the siphon principle, the height difference between the moving U-shaped tube 22 and the fixed vertical tube 23 will affect the pressure difference generated by the siphon. The greater the height difference, the greater the pressure difference, and the greater the flow rate of the medicine per unit time. Conversely, the smaller the height difference, the smaller the flow rate, thereby achieving the adjustment of the output of the medicine per unit time.On the other hand, rotating the regulating disc 28 causes the regulating rod 27 and valve plate 29 to rotate within the ball valve 26, changing the opening and closing degree of the valve plate 29, thereby controlling the flow area of the fixed vertical pipe 23. A smaller flow area results in greater resistance to the flow of the agent and a lower output; a larger flow area results in a higher output. This method allows for more precise control of the agent's output and indirectly affects the water pressure within the pipeline, ensuring the stability and accuracy of the agent delivery.
