Embodiment 1

[0035] Such as Figure 1-Figure 3 As shown, a safe discharge-free continuous crushing device for waste power batteries of the present invention includes a crushing bin 1, and a feeding mechanism is provided on the top of the crushing bin 1, and the feeding mechanism includes a feeding hopper 2 located above, and a feeding hopper 2 The feed pipe 3 connected at the bottom, the feed hopper 2 is a conical feed hopper or a rectangular cone feed hopper for convenient feeding, the feed pipe 3 is fixed on the top of the crushing bin 1 and connected to the bottom of the crushing bin 1 The inner cavities are connected, and a heavy hammer flap valve 4 is set between the feed hopper 2 and the feed pipe 3 to seal the gas. The recovered waste power batteries are directly fed into the feed hopper 2, sealed and air-tight through the heavy hammer flap valve 4, and then fed into the crushing bin 1 through the feed pipe 3.

[0036] The crushing chamber 1 is provided with a crushing mechanism 5,...

Embodiment 2

[0052] The structure of a safe discharge-free continuous crushing equipment for waste power batteries in this embodiment is basically the same as that of Embodiment 1, the only difference is that in this embodiment, a row of sprinklers is arranged horizontally on the upper part of the inner cavity of the crushing bin 1. Mechanism 13, the inlet of spray mechanism 13 communicates with liquid inlet 8. When working, the equipment in this embodiment no longer allows the crushing mechanism 5 to be immersed in water, but uses the spray liquid method to take away the heat released by the battery discharge, which can also achieve the same effect as the first embodiment.

Abstract

The invention discloses safe waste power battery discharge-free continuous crushing equipment which comprises a crushing bin. A feeding mechanism is arranged at the top end of the crushing bin and comprises a feeding hopper and a feeding pipe, and a heavy hammer flap valve is arranged between the feeding hopper and the feeding pipe; a crushing mechanism is arranged in the crushing bin, and the crushing mechanism can crush battery materials fed from the feeding pipe; a discharging opening is formed in the lower portion of the bottom of the crushing bin, and a discharging valve is arranged on the discharging opening; a discharging screw is arranged at the bottom of the crushing bin and can convey crushed materials to the discharging opening in a centralized mode; a liquid inlet and an air inducing opening are formed in the upper part of the crushing bin, and a tail gas induced draft fan works to keep the crushing bin in a micro-negative pressure state all the time; and a sight glass is arranged on a bin body of the crushing bin. The equipment is capable of realizing safe, environment-friendly, discharge-free, continuous and reliable operation and high in production efficiency, and meanwhile, water vapor generated by crushing discharge conversion can be reasonably and effectively utilized.

Description

technical field [0001] The invention relates to the technical field of recycling waste power batteries, and more specifically, relates to a safe discharge-free continuous crushing equipment for waste power batteries. Background technique [0002] Waste batteries that cannot be used in stages have a certain amount of power, such as 18650 cylindrical batteries with a voltage of 3.0V to 4.2V, the remaining power is about 200mA.h to 2200mA.h, and the remaining power of a 1kg soft pack battery is about 1100mA.h ~42000mA.h, in order to prevent the safety problems caused by broken and short-circuited waste batteries and the difficulty of effective withdrawal due to instantaneous discharge and heat, at present, almost all the recycling of waste power batteries that cannot be used in cascades or whose life is exhausted in cascades is soaked The battery is chemically discharged in salt water, then mechanically crushed, and then smelted and reduced through chemical methods such as pyro...
