Description

Technical Field

[0001] The utility model relates to the technical field of processing of nuclear industry decontaminants, and particularly to a processing and mixing device for a nuclear industry decontaminant containing diethylenetriamine pentaacetic acid sodium salt. Background Technique

[0002] The processing and mixing device for a nuclear industry decontaminant containing diethylenetriamine pentaacetic acid sodium salt is a special equipment designed for removing radioactive pollutants in nuclear facilities. It can mix various chemical components (such as organic acids, complexing agents, surfactants, etc.) in precise proportions to form an efficient and safe decontaminant for cleaning and removing radioactive pollutants on the surfaces of nuclear facility components. The processing and mixing device for a nuclear industry decontaminant containing diethylenetriamine pentaacetic acid sodium salt can process alkaline decontaminants, acidic decontaminants, and neutral decontaminants. Some existing processing and mixing devices for a nuclear industry decontaminant containing diethylenetriamine pentaacetic acid sodium salt use a single-axis unidirectional rotation method to achieve the mixing of various raw materials of the decontaminant. For some processing and mixing devices for a nuclear industry decontaminant containing diethylenetriamine pentaacetic acid sodium salt, the preparation work of the decontaminant raw materials is carried out by manually preparing the proportion of each raw material in advance. Such processing and mixing devices for a nuclear industry decontaminant containing diethylenetriamine pentaacetic acid sodium salt have the following problems. For example, the single-axis unidirectional rotation method limits the coverage range of the stirring unit and at the same time limits the stirring and mixing effect. Manually preparing each raw material according to the proportion increases the workload of the staff and at the same time affects the feeding efficiency of the processing and mixing of the decontaminant.

When the motor 6 operates, the output shaft of the motor 6 rotates to drive the driving wheel 5 to rotate. The driving wheel 5 drives the driven wheel 4 to rotate through the transmission belt. The driven wheel 4 rotates to drive the rotating column 21 to rotate. The rotating column 21 rotates to drive the propeller blades 12 to rotate.

At the same time, the rotating column 21 rotates to drive the driving frame 22 to rotate. The driving frame 22 rotates to drive the four stirring rods 23 to rotate around the central axis of the rotating column 21. The rotation of the stirring rods 23 drives the sliding blocks 27 to rotate in a waveform under the guiding action of the corresponding corrugated guide rails 26, so that the stirring rods 23 rotate in a waveform, realizing the stirring and mixing of the decontamination agent raw materials on the outer layer of the mixing bin 1 and improving the mixing effect of the decontamination agent raw materials;

[0023] Weighing and feeding mechanism 3: It is arranged at the upper end of the mixing bin 1, and the connecting pipes are all fitted and installed with the lower end of the weighing and feeding mechanism 3. The weighing and feeding mechanism 3 includes a feeding bin 31, a feeding hopper 32, a connecting hose 33, a spring 36 and a telescopic column 37.

The upper end of the pressure sensor 35 is in contact with the lower end of the feeding bin 31. The pressure sensor 35 is bidirectionally electrically connected to the controller 11. The controller 11 enables the operation of the pressure sensor 35 and sequentially fills various raw materials into the feeding bin 31. When the raw materials enter the feeding bin 31, gravity causes the feeding bin 31 to move downward, the telescopic ends of the telescopic columns 37 contract, and at the same time the springs 36 are elastically compressed. Gravity acts on the detection end of the pressure sensor 35, and the pressure sensor 35 transmits the pressure information to the signal receiving end of the controller 11 in real time. The controller 11 analyzes and integrates the raw materials and then records them. The core raw material is diethylenetriamine pentaacetic acid sodium salt, and its proportion in each raw material of the detergent is 1%.

[0024] Among them: Symmetrically distributed brackets 7 are fixedly connected to the lower end of the mixing bin 1. The front end of the right surface of the front bracket 7 is provided with a controller 11. The input end of the controller 11 is electrically connected to an external power supply;

[0025] Among them: A feeding pipe 10 is arranged at the lower end of the mixing bin 1. An electric valve 9 is arranged in the middle of the feeding pipe 10. The input end of the electric valve 9 is electrically connected to the output end of the controller 11.

[0026] The working principle of a processing and mixing device for a nuclear industry decontamination agent containing diethylenetriamine pentasodium is as follows: During operation, personnel first stably place the mixing chamber 1, the feed bin 31, and other mechanisms on a horizontal working area through the support 7. After stable placement, the controller 11 enables the pressure sensor 35 to operate. Personnel sequentially add various raw materials into the feed bin 31. When the raw materials enter the feed bin 31, gravity causes the feed bin 31 to move downward, the telescopic end of the telescopic column 37 contracts, and at the same time, the springs 36 are elastically compressed. Gravity acts on the detection end of the pressure sensor 35, and the pressure sensor 35 transmits the pressure information to the signal receiving end of the controller 11 in real time. The controller 11 analyzes and integrates the raw materials and then records them. After the recording is completed, personnel enable the operation of the first electric valve 34 through the controller 11. The first electric valve 34 opens, and the raw materials enter the connecting pipe through the connecting hose 33 and then enter the mixing chamber 1, sequentially realizing the feeding of each decontamination agent raw material in proportion. After the feeding is completed, personnel enable the operation of the motor 6 through the controller 11. The output shaft of the motor 6 rotates to drive the driving wheel 5 to rotate. The driving wheel 5 drives the driven wheel 4 to rotate through the transmission belt. The rotation of the driven wheel 4 drives the rotation column 21 to rotate. The rotation of the rotation column 21 drives the propeller blade 12 to rotate. The rotation of the propeller blade 12 realizes the stirring of each decontamination agent raw material at the center position of the mixing chamber 1. At the same time, the rotation of the rotation column 21 drives the driving frame 22 to rotate. The rotation of the driving frame 22 drives the four stirring rods 23 to rotate around the central axis of the rotation column 21. The rotation of the stirring rods 23 drives the sliding blocks 27 to rotate in a waveform under the guiding action of the corresponding waveform guide rails 26, thereby causing the stirring rods 23 to rotate in a waveform, realizing the stirring and mixing of the decontamination agent raw materials on the outer layer of the mixing chamber 1 and improving the mixing effect of the decontamination agent raw materials. After the mixing is completed, personnel enable the operation of the second electric valve 9 through the controller 11. The second electric valve 9 opens, and the mixed decontamination agent is removed through the discharge pipe 8.

[0027] It should be noted that the controller 11 controls the operation of the first electric valve 34, the pressure sensor 35, the motor 6, and the second electric valve 9 using methods commonly used in the prior art.
