[0035] Embodiment 1

[0036] Please refer toFigures 1-4 As shown in the figure, the utility model provides a welding powder mixing equipment with a protection device. Technical solution: A welding powder mixing equipment with a protection device includes a tank body 1, an inlet 2 and a discharge pipe 3 are arranged on the tank body 1, a support 4 is fixedly connected to the bottom of the tank body 1, and a protection mechanism 5 for preventing material overflow and temperature warning and a mixing mechanism 6 for mixing are arranged in the tank body 1;

[0037] The protection mechanism 5 includes a protective cover 501, a limiting ring 502, a dust-proof cover 503, a temperature sensor 504, an alarm 505, and a control box 506. The protective cover 501 is connected to the top end of the mixing mechanism 6. The limiting ring 502 is fixedly connected to the tank body 1 above the protective cover 501. The dust-proof cover 503 is hinged to the tank body 1 above the inlet 2. The temperature sensor 504 is arranged on the inner upper wall of the tank body 1. The alarm 505 is arranged on the outer side of the tank body 1. The control box 506 is arranged at one end of the outer side of the tank body 1 close to the alarm 505. The control box 506 is connected to the temperature sensor 504 and the alarm 505 for control.

[0038] The mixing mechanism 6 includes a driving motor 601, a mixing shaft 602, and a plurality of mixing blades 603. The driving motor 601 is fixedly arranged at the bottom of the tank body 1. The mixing shaft 602 is connected to the output end of the driving motor 601. The mixing blades 603 are arranged on the mixing shaft 602.

[0039] The protective cover 501 is made of a soft rubber material that can be freely bent.

[0040] Silicone sealing strips 507 are arranged on the edges of both the dust-proof cover 503 and the inlet 2, which can further prevent the material dust from overflowing.

[0041] A silicone sealing ring 508 that matches the storage tank opening is arranged on the outer side of the discharge pipe 3, which can make the material completely fall into the storage tank without dust overflow.

[0042] The inner bottom of the tank body 1 bulges upward. The number of the discharge pipes 3 is two, which are respectively arranged at the lowest positions at both ends of the bottom of the tank body 1, facilitating smooth discharging, reducing the residue of the material in the tank body 1. A valve is arranged on the discharge pipe 3 to control the discharging speed.

[0043] The part of the mixing blade 603 close to the bulge at the bottom of the tank body 1 is parallel to the bottom of the tank body 1, which can reduce the mixing dead angle and make the mixing more uniform.

[0044] The working principle of the utility model is as follows:

[0045] When the welding powder mixing equipment with a protection device in this embodiment is in use, the material is put in from the feed inlet 2. The material enters the mixing mechanism 6 through the gap between the protective cover 501 and the limiting ring 502. The dust-proof cover 503 is closed to prevent the material from overflowing. The power supply is started, and the output end of the driving motor 601 drives the mixing shaft 602 to rotate. The mixing blades 603 on the mixing shaft 602 mix the material. The soft rubber protective cover 501 at the upper end of the mixing shaft 602 turns up at the edge due to the centrifugal force. The limiting ring 502 limits the folding angle of the protective cover 501 to control the contact between the limiting ring 502 and the protective cover 501 to form a sealed space to prevent the material from overflowing. During the mixing process, the temperature sensor 504 monitors the temperature in the tank body 1. When the temperature monitored by the temperature sensor 504 exceeds the standard range, the control box 506 controls the alarm 505 to give an alarm. After the mixing mechanism 6 stops working, opening the discharge pipe 3 can complete the discharging.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
