[0002] In the production of powdered emulsion explosives, a powder-forming tower is needed to assist in powder formation. The existing powder-forming tower structure cannot completely turn the emulsion explosive material sprayed from the nozzle into powder. This is because some of the material droplets are scattered by the airflow and fall onto the inner wall of the tower and deposit together. This greatly affects the yield of the finished powder product and needs to be improved. Therefore, a powder-forming tower was designed. Utility Model Content

[0017] Reference Figure 1-4 The powder-making tower includes an outer tower body 1, an inner tower body 2 inside the outer tower body 1, multiple connecting structures 3 fixed between the outer tower body 1 and the inner tower body 2, multiple shaking plates 4 fixed on the outer side wall of the inner tower body 2, and a vibration motor 5 fixed on the side wall of the shaking plate 4. In actual production, the installation position and number of vibration motors 5 are determined by the nozzle 64 used, and can be adjusted according to the dispersion rate of the medicine in a unit space. Vibration motors 5 are installed in positions where medicine deposition is likely to occur. A feed hopper 6 is fixed at the top of the outer tower body 1, and a discharge hopper 7 is set at the bottom of the inner tower body 2. A soft sleeve 8 is fixed between the inner tower body 2 and the discharge hopper 7. During operation, the tower body is connected to the ground with a grounding wire.

[0018] The connecting structure 3 includes a first mounting plate 31 fixed to the inner side wall of the outer tower body 1 and a second mounting plate 32 fixed to the outer side wall of the inner tower body 2. Multiple telescopic rods 33 are fixed between the first mounting plate 31 and the second mounting plate 32. Each telescopic rod 33 is fitted with a spring 34 on its outside. The spring 34 plays a major supporting role, and the telescopic rod 33 plays a limiting role.

[0019] Multiple flexible rods 41 are fixedly and interspersed on the side wall of the shaking plate 4. Multiple through holes 21 are opened on the side wall of the inner tower body 2 for mounting the flexible rods 41. The flexible rods 41 are used to contact the floating drug droplets, mainly the drug droplets at the extreme position of the spray, to prevent the drug droplets from depositing on the inner wall of the inner tower body 2. By setting the flexible rods 41, the drug can be better thrown out under the vibration of the vibration motor 5.

[0020] A feed pipe 63 is fixed to the top of the feed hopper 6. One end of the feed pipe 63 extends into the inner tower body 2 and is fixed with a nozzle 64.

[0021] A hot air inlet 61 is fixed to the side wall of the feed hopper 6. The hot air inlet 61 is connected to a warm air pipe to supply warm air for drying the medicinal material droplets into powder. A uniform air distribution plate 62 is fixed to the bottom of the feed hopper 6 to distribute the air evenly. An air outlet 71 is fixed to the side wall of the discharge hopper 7. The air outlet 71 is connected to a dust filter to filter out the fine powder in the warm air. The above is the structure of a conventional powder making tower, which is not shown in the figure.

[0022] A support platform 9 is fixed to the bottom of the outer tower body 1, and a support frame 10 is fixed to the outer side wall of the discharge hopper 7.

[0023] A terminal controller 11 is fixed on the outer wall of the outer tower body 1. The terminal controller 11 is connected to the vibration motor 5 by signal. By observing the powder discharge situation at the bottom of the discharge bin 7, the working status of the vibration motor 5 can be adjusted in a timely manner.

[0024] When this device is in use, the explosive material is introduced into the feed hopper 6 and sprayed out discretely by the nozzle 64. Simultaneously, dry warm air is introduced into the hot air outlet 61 to dry and pulverize the explosive droplets. Some of the dried emulsion explosive powder falls into the discharge hopper 7 and is discharged from the bottom of the discharge hopper 7. Some of the emulsion explosive powder enters the air outlet 71 with the warm air and is collected after subsequent dust separation treatment. When the nozzle 64 sprays the discrete explosive material, some of the material falls onto the inner wall of the inner tower 2 or the surface of the supporting flexible rod 41. During the drying and pulverization process, the vibration motor 5 is kept working to discharge the fallen explosive material in a timely manner, preventing the explosive material from continuously accumulating and forming large lumps. The explosive material that is shaken out by vibration can still maintain a small structural feature after drying, improving the quality of the powdered product.
