Description

Technical Field

[0001] This utility model belongs to the field of hazardous waste solidification agent treatment technology, specifically relating to a quantitative feeding mechanism for a hazardous waste solidification agent dispensing and stirring device. Background Technology

[0002] In the field of hazardous waste treatment, solidification is a commonly used and important technical method. By adding a solidifying agent to hazardous waste and thoroughly mixing it, the toxicity, migration, and leaching properties of hazardous waste can be reduced, enabling it to meet the standards for safe disposal.

[0003] However, in existing hazardous waste solidification agent dosing and mixing devices, the quantitative feeding process often presents numerous problems. Traditional feeding methods may rely on manual estimation or simple mechanical control, making it difficult to achieve precise, stable, and adjustable quantitative feeding.

[0004] Manual feeding is not only inefficient, but also prone to inaccurate dosage of curing agent due to human factors, thus affecting the effectiveness and quality of the curing process. Excessive curing agent will lead to resource waste and increased costs, while insufficient dosage may fail to achieve the expected stabilization and detoxification standards for hazardous waste.

[0005] Some mechanically controlled feeding devices may suffer from complex structures, inconvenient operation, and high maintenance costs. Some devices also lack the flexibility to adjust the amount of solidifying agent added based on different types and quantities of hazardous waste, exhibiting poor adaptability.

[0006] To address this, we propose a quantitative feeding mechanism for a hazardous waste solidification agent mixing device. This device not only enables precise and controllable quantitative feeding but also adapts to different treatment needs, and features a simple structure and convenient operation. Utility Model Content

[0007] The purpose of this invention is to provide a quantitative feeding mechanism for a hazardous waste solidification agent dispensing and mixing device. This device can not only achieve precise and controllable quantitative feeding, but also adapt to different processing needs, and has a simple structure and is easy to operate.

[0008] The specific technical solution adopted in this utility model is as follows:

[0009] A quantitative feeding mechanism for a hazardous waste solidification agent dispensing and mixing device includes a mixing cylinder. The top of the mixing cylinder has multiple mounting holes, and each mounting hole is equipped with a feeding shell. The feeding shell is composed of a conical support shell and a cylindrical quantitative cylinder. The conical support shell is connected to the cylindrical quantitative cylinder. The cylindrical quantitative cylinder has multiple equidistant rotating holes, and each rotating hole is equipped with a rotating shaft. A gear is installed at one end of the rotating shaft, and a rotating disk that matches the cylindrical quantitative cylinder is installed at the other end of the rotating shaft.

[0010] A telescopic assembly is provided at the center of the top of the mixing cylinder. A first connecting plate is installed at the telescopic end of the telescopic assembly. A connecting rod is provided on the outside of the first connecting plate. The bottom of the connecting rod passes through the mixing cylinder and is installed with a connecting plate. The connecting plate has meshing teeth for gear engagement on one side.

[0011] Furthermore, a cross groove is provided on the rotating shaft, a connecting post is installed on one side of the gear, and a cross block that matches the cross groove is provided on the connecting post.

[0012] Furthermore, a first magnetic surface is provided inside the cross groove, and a second magnetic surface that attracts the first magnetic surface is provided on the cross block.

[0013] Furthermore, the telescopic assembly includes an electrically operated telescopic rod disposed at the center of the top of the mixing drum, the telescopic end of which is connected to the first connecting disc.

Multiple equidistant rotating holes are provided on the cylindrical quantitative cylinder 4. Each rotating hole is provided with a rotating shaft 5. A gear 6 is installed at one end of the rotating shaft 5, and a rotating disk 7 that matches the cylindrical quantitative cylinder 4 is installed at the other end of the rotating shaft 5.

[0026] A telescopic assembly is provided at the center of the top of the mixing cylinder 1. A first connecting plate 8 is installed at the telescopic end of the telescopic assembly. A connecting rod 9 is provided on the outside of the first connecting plate 8. The bottom of the connecting rod 9 passes through the mixing cylinder 1 and is installed with a connecting plate 10. A meshing tooth 11 of a gear 6 is provided on one side of the connecting plate 10.

[0027] In order to facilitate the selection of the desired hazardous waste solidification dosage, a cross groove 12 is provided on the rotating shaft 5, and a connecting column is installed on one side of the gear 6. A cross block 13 matching the cross groove 12 is provided on the connecting column.

[0028] Furthermore, a first magnetic surface is provided inside the cross groove 12, and a second magnetic surface is provided on the cross block 13 that attracts the first magnetic surface. This arrangement can fix the gear 6 and prevent it from falling off during rotation.

[0029] Meanwhile, the telescopic assembly includes an electric telescopic rod 14 located at the center of the top of the mixing drum 1. The telescopic end of the electric telescopic rod 14 is connected to the first connecting plate 8, and the electric telescopic rod 14 drives the first connecting plate 8 to move up and down.

[0031] A motor 19 is installed at the bottom of the mixing cylinder 1. A rotating rod 20 located inside the mixing cylinder 1 is installed at the output end of the motor 19. Stirring rods 21 arranged alternately are provided on the outside of the rotating rod 20.
