Description

Technical Field

[0001] This utility model relates to the field of zinc powder processing technology, and in particular to a closed powder discharge device for the production of distilled metallic zinc powder. Background Technology

[0002] Distilled zinc powder is produced by heating solid zinc to evaporate it into zinc vapor. The zinc vapor then enters a dispersion and condensation device through a gas guide pipe. After dispersion and condensation, it forms zinc powder that falls to the bottom of a cooling tank. Finally, it is released from the bottom of the cooling tank and sent to a grading workshop for particle size classification, producing zinc powder of different particle sizes, which is the final product. To ensure the quality of the zinc powder, the entire process from heating and evaporating solid zinc to dispersing and condensing it into zinc powder, and finally falling to the bottom of the cooling tank, is carefully controlled.

[0003] The zinc powder falling to the bottom of the cooling tank is discharged using a rotary valve that rotates throughout the process. However, this method is prone to jamming by zinc nodules generated during the condensation process, making discharge impossible. Furthermore, due to the continuous operation of the rotary valve, the zinc powder is squeezed between the scraper and the rotary valve, causing zinc scale to stick to the scraper. This prevents the rotary valve from working properly and requires cleaning after a period of time, increasing labor intensity, resulting in low production efficiency, high operating costs, and unstable product quality. In view of this, a closed powder discharge device for the production of distilled zinc powder is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a closed powder discharge device for the production of distilled zinc powder, which can solve the above-mentioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a closed powder discharge device for the production of distilled zinc powder, comprising a cooling tank, wherein a discharge pipe is fixedly connected to the bottom of the cooling tank, and a motor is fixedly connected to the discharge pipe;

[0006] The bottom of the cooling tank is fixedly connected to a sealing pipe located inside the discharge pipe, and a solenoid valve is installed on the sealing pipe.

[0007] The discharge pipe is rotatably connected to a discharge ball, and a connecting shaft is fixedly connected to one side of the discharge ball. The connecting shaft is fixedly connected to the output end of the motor.

[0008] The discharge ball has four discharge slots arranged in a cross-shaped array.

[0009] Preferably, a funnel-shaped guide tube is fixedly connected inside the discharge pipe, and the bottom of the guide tube is in contact with the surface of the discharge ball;

[0010] Two hemispherical protective blocks are fixedly connected to the inner wall of the discharge pipe;

[0011] The discharge ball is located inside the protective block.

[0012] Preferably, a gap equal to the diameter of the trough is left between the two protective blocks.

[0013] Preferably, a telescopic rod is fixedly connected inside the discharge trough, and an adjusting plate is fixedly connected to the output end of the telescopic rod, with the adjusting plate slidably connected inside the discharge trough.

[0014] A power source is rotatably connected to the discharge ball, and the power source is electrically connected to the telescopic rod. The power source passes through the discharge pipe and is rotatably connected to it.

[0015] Preferably, a sealing gasket is fixedly connected to the outside of the guide tube.

[0016] Preferably, a sealing strip is fixedly connected to the outer side of the adjusting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This closed-loop powder discharge equipment for the production of distilled zinc powder activates a solenoid valve when zinc powder needs to be discharged, allowing the zinc powder to be discharged through a sealed pipe. The zinc powder falls into the discharge trough, prompting the motor to start. The motor's output drives the discharge ball to rotate. As the discharge ball rotates, the discharge trough changes from an upward-opening to a downward-opening state. Under gravity, the zinc powder is automatically discharged from the inside of the discharge trough. The guide pipe ensures precise discharge of the zinc powder into the discharge trough, preventing it from drifting aimlessly inside the discharge pipe and adhering to the surface of the discharge ball, thus avoiding waste. Simultaneously, the protective block prevents zinc powder overflow when the discharge trough is in a horizontal position, ensuring more accurate quantity discharge each time.

[0019] 2. This closed powder discharge equipment for the production of distilled zinc powder can be powered by a power source to control the start and stop of the telescopic rod. The output end of the telescopic rod can then be used to adjust the position of the regulating plate, thereby changing the volume of the discharge trough and allowing zinc powder to be discharged quantitatively according to demand.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a closed powder discharge device for the production of distilled zinc powder, including a cooling tank 1, a discharge pipe 2 fixedly connected to the bottom of the cooling tank 1, and a motor 3 fixedly connected to the discharge pipe 2;

[0032] The bottom of the cooling tank 1 is fixedly connected to a sealing pipe 8 located inside the discharge pipe 2, and a solenoid valve 9 is installed on the sealing pipe 8;

[0033] The discharge pipe 2 is rotatably connected to a discharge ball 4, and a connecting shaft 5 is fixedly connected to one side of the discharge ball 4. The connecting shaft 5 is fixedly connected to the output end of the motor 3.

[0034] The discharge ball 4 is provided with a discharge chute 10. There are four discharge chute 10s, which are arranged in a cross-shaped array.

[0035] The cooling tank 1 is connected to the condensation and dispersion device of the still. Therefore, after distillation, the zinc powder is condensed under the condensation and dispersion device and falls into the cooling tank 1 to complete the collection of zinc powder. When it is necessary to discharge the zinc powder, the solenoid valve 9 is activated so that the zinc powder is discharged through the sealing pipe 8. At this time, the zinc powder falls into the inside of the discharge trough 10. Therefore, the motor 3 is activated. The output end of the motor 3 drives the discharge ball 4 to rotate. As the discharge ball 4 rotates, the discharge trough 10 changes from an upward opening to a downward opening. Therefore, under the action of gravity, the zinc powder is automatically discharged from the inside of the discharge trough 10.

[0036] Furthermore, a funnel-shaped guide pipe 6 is fixedly connected inside the discharge pipe 2, and the bottom of the guide pipe 6 is in contact with the surface of the discharge ball 4.

[0037] Two hemispherical protective blocks 11 are fixedly connected to the inner wall of the discharge pipe 2;

[0038] The discharge ball 4 is located inside the protective block 11, and a gap equal to the diameter of the material trough 10 is left between the two protective blocks 11;

[0039] The guide pipe 6 allows zinc powder to be accurately discharged into the discharge trough 10, preventing zinc powder from drifting randomly inside the discharge pipe 2 and thus avoiding zinc powder adhering to the surface of the discharge ball 4 and causing waste. At the same time, the protective block 11 can prevent zinc powder from overflowing when the discharge trough 10 is in a horizontal position, thus ensuring that the amount of each discharge is more accurate.

[0040] Furthermore, a telescopic rod 15 is fixedly connected inside the discharge trough 10, and an adjusting plate 13 is fixedly connected to the output end of the telescopic rod 15. The adjusting plate 13 is slidably connected inside the discharge trough 10.

[0041] A sealing strip 14 is fixedly connected to the outer side of the adjusting plate 13;

[0042] A power supply 12 is rotatably connected to the discharge ball 4. The power supply 12 is electrically connected to the telescopic rod 15. The power supply 12 passes through the discharge pipe 2 and is rotatably connected to it.

[0043] The power supply 12 can be used to control the start and stop of the telescopic rod 15, and the position of the adjustment plate 13 can be adjusted through the output end of the telescopic rod 15, thereby changing the volume of the discharge trough 10, so that zinc powder can be discharged quantitatively according to demand.

[0044] The sealing strip 14 ensures the sealing effect between the regulating plate 13 and the discharge chute 10, thereby preventing zinc powder leakage.

[0045] Furthermore, a sealing gasket 7 is fixedly connected to the outside of the guide tube 6;

[0046] The sealing gasket 7 ensures the sealing performance between the guide pipe 6 and the discharge pipe 2, thereby preventing zinc powder from drifting.

[0047] Working principle: The cooling tank 1 is connected to the condensation and dispersion device of the still. Therefore, after distillation, the zinc powder is condensed under the condensation and dispersion device and falls into the cooling tank 1 to complete the collection of zinc powder. When it is necessary to discharge the zinc powder, the solenoid valve 9 is activated, so that the zinc powder is discharged through the sealing pipe 8. At this time, the zinc powder falls into the inside of the discharge trough 10. Therefore, the motor 3 is activated. The output end of the motor 3 drives the discharge ball 4 to rotate. As the discharge ball 4 rotates, the discharge trough 10 changes from an upward opening to a downward opening. Therefore, under the action of gravity, the zinc powder is automatically discharged from the inside of the discharge trough 10.

[0048] The guide pipe 6 allows zinc powder to be precisely discharged into the discharge trough 10, preventing it from drifting randomly inside the discharge pipe 2 and thus avoiding waste caused by zinc powder adhering to the surface of the discharge ball 4. At the same time, the protective block 11 can prevent zinc powder from overflowing when the discharge trough 10 is in a horizontal position, thus ensuring more accurate quantity of each discharge.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
