[0002] When treating wastewater, which contains a large amount of sludge, the wastewater is first settled to remove the sludge. However, this sludge contains various harmful substances. To reduce environmental pollution, chemicals are used to neutralize these harmful substances before discharge. Currently, when preparing existing chemicals, a certain amount of residual chemicals remains inside the pipes and mixing devices. This results in insufficient chemical concentration when mixing with the sludge, leading to incomplete neutralization of harmful substances. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage reagent metering and dispensing device for sludge pretreatment to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a multi-stage reagent metering and dispensing device for sludge pretreatment, including a guide cover, the guide cover being a hollow spherical structure, the inside of the guide cover being provided with a dispensing component, a support ring and a rotating ball, the end of the dispensing component near the support ring being fixedly connected to the rotating ball, and the rotating ball being slidably connected in the inner hole of the support ring, used to limit and fix the dispensing component, and at the same time to facilitate the adjustment of the angle of the dispensing component;

[0005] The upper end of the liquid dispensing component is provided with a liquid dispensing chamber in the middle, the lower end of the liquid dispensing chamber passes through a rotating ball, the upper end of the guide cover is fixedly connected with a feed pipe, the outlet of the feed pipe is located in the liquid dispensing chamber, and a vibration ring for collision vibration is fixedly connected to the outer wall of the outlet.

[0006] A blocking ring and a limiting protrusion are fixedly connected to the inner wall of the liquid preparation chamber. A weighing sensor is provided in the inner hole of the blocking ring. A support member that changes the position of the weighing sensor is fixedly connected to the lower end of the weighing sensor. The limiting protrusion is used to limit the movement of the weighing component.

[0007] Preferably, the liquid dispensing component has a spherical cap structure, and the upper sidewall of the liquid dispensing component abuts against the inner sidewall of the guide cover and slides along the inner sidewall of the guide cover, so that the liquid dispensing chamber collides with the oscillating ring to remove residual raw materials in the feed pipe and the liquid dispensing chamber.

[0008] Preferably, the sidewall of the support ring is inclined, and an electric actuator is fixed to the sidewall of the support ring facing the liquid dispensing component by screws. The power output end of the electric actuator abuts against the side end of the liquid dispensing component to drive the liquid dispensing component to rotate.

[0009] Preferably, at least three springs are fixedly connected between the support ring and the side wall of the liquid dispensing component, and the springs are arranged around the rotating ball to support the liquid dispensing component and reset after rotation.

[0010] Preferably, the upper half of the support member is a circular ring structure, the lower half of the support member is an L-shaped columnar structure, and an iron counterweight ball is fixedly connected to the lower top of the support member to control the height of the support member.

[0014] The beneficial effects of this invention are as follows: During the solution preparation process, the solution preparation component is driven to rotate by the electric actuator, causing the solution preparation chamber to collide with the oscillating ring of the feed pipe, thereby shaking the residual drug in the feed pipe into the solution preparation chamber. At the same time, the solution preparation component can mix the drug solution evenly during the rotation process. After the solution preparation is completed, the collision between the solution preparation chamber and the oscillating ring of the feed pipe causes the mixed drug solution in the solution preparation chamber to be discharged, greatly reducing the residual drug solution. This ensures that the amount of drug solution is sufficient when the drug is mixed with the sludge, ensuring that harmful substances in the sludge are fully neutralized and avoiding environmental impact.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] See Figures 1-4 The present invention provides a multi-stage reagent metering and dispensing device for sludge pretreatment, comprising a guide cover 3, which is a hollow spherical structure. Inside the guide cover 3 are a dispensing component 4, a support ring 5, and a rotating ball 16. One end of the dispensing component 4 near the support ring 5 is fixedly connected to the rotating ball 16. The rotating ball 16 is slidably connected in the inner hole of the support ring 5, which is used to limit and fix the dispensing component 4, and at the same time facilitates the adjustment of the angle of the dispensing component 4. The liquid dispensing component 4 has a spherical cap structure. The upper sidewall of the liquid dispensing component 4 abuts against the inner sidewall of the guide cover 3 and slides along the inner sidewall of the guide cover 3. The upper middle of the liquid dispensing component 4 is provided with a liquid dispensing chamber 10. The lower end of the liquid dispensing chamber 10 passes through the rotating ball 16. The upper middle of the guide cover 3 is fixedly connected to the feed pipe 6. The outlet of the feed pipe 6 is located in the liquid dispensing chamber 10, and the outer sidewall of the outlet is fixedly connected to a collision and vibration ring 7, so that the liquid dispensing chamber 10 and the vibration ring 7 collide with each other, thereby generating vibration. This vibration can remove residual raw materials in the feed pipe 6 and the liquid dispensing chamber 10, ensuring that the raw materials can fully enter the liquid dispensing chamber 10.

[0022] The sidewall of the support ring 5 is inclined. An electric actuator 8 is fixed to the sidewall of the support ring 5 facing the liquid preparation component 4 by screws. The power output end of the electric actuator 8 abuts against the side of the liquid preparation component 4 to drive it to rotate. At least three springs are fixedly connected between the support ring 5 and the sidewall of the liquid preparation component 4, and the springs are arranged around the rotating ball 16 to support the liquid preparation component 4 and reset after rotation. The springs support the liquid preparation component 4, ensuring that it is in the correct position each time liquid is prepared. When the electric actuator 8 pushes the liquid preparation component 4 to rotate, it can stretch or compress the springs, thereby ensuring the accuracy and repeatability of liquid preparation. The liquid preparation component 4 can mix the liquid entering the liquid preparation chamber 10 when it rotates.

[0023] A blocking ring 15 and a limiting protrusion 14 are fixedly connected to the inner wall of the liquid preparation chamber 10. A weighing sensor 11 is provided in the inner hole of the blocking ring 15. A support member 12 that changes the position of the weighing sensor 11 is fixedly connected to the lower end of the weighing sensor 11. The limiting protrusion 14 is used to limit the movement of the weighing member. The upper half of the support member 12 is a circular ring structure, and the lower half of the support member 12 is an L-shaped columnar structure. An iron counterweight ball 13 is fixedly connected to the lower top of the support member 12 to control the height of the support member 12. When the medicine enters the liquid preparation chamber 10, the weighing sensor 11 is located in the middle of the blocking ring 15. The weighing sensor 11 weighs the entering medicine to ensure the correct dosage.

[0024] The upper sidewall of the blocking ring 15 is inclined, the upper half of the inner hole of the blocking ring 15 is vertical, and the lower half of the inner hole of the blocking ring 15 is inclined. The upper end of the support member 12 abuts against the lower half of the inner hole of the blocking ring 15. The support member 12 seals the blocking ring 15, and the agent will not leak from the gap between the blocking ring and the support member, ensuring the sealing during liquid preparation.

[0025] The limiting protrusion 14 is located below the blocking ring 15. The limiting protrusion 14 has a semi-oval structure. When the liquid preparation chamber 10 is completed, the limiting protrusion 14 abuts against the lower side of the upper half of the support member 12. After the liquid preparation is completed, the support member 12 moves under the influence of the counterweight ball 13. The limiting protrusion 14 blocks the support member 12, so that there is a gap between the support member 12 and the liquid preparation chamber 10, so that the liquid can be discharged smoothly.

[0026] The liquid preparation device also includes a mixing cylinder 1. A sealing cap 2 is fixedly connected to the upper end of the mixing cylinder 1 via a snap-fit. A guide cap 3 is fixedly connected to the middle of the sealing cap 2. An electromagnet 9 is fixedly connected to the lower end face of the support ring 5 via screws. The electric actuator 8, electromagnet 9, and weighing sensor 11 are all connected to the device control terminal for data transmission and operation control. The control terminal enables centralized control and data transmission of the electric actuator 8, electromagnet 9, and weighing sensor 11, improving the automation level and ease of operation of the device. It facilitates real-time monitoring and adjustment of the liquid preparation process. Before liquid preparation, the electromagnet 9 is energized, attracting the iron counterweight ball 13, thereby sealing the inner hole of the blocking ring 15 with the support member 12. After liquid preparation is completed, the electromagnet is de-energized, and the support member 12 automatically moves under the gravity of the iron counterweight ball 13. During and after liquid preparation, the electric actuator 8 drives the liquid preparation component 4 to rotate, removing any remaining raw material residue in the feed pipe 6 and the liquid preparation chamber 10.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
