Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery equipment, in particular to a bubble suppression mechanism for material dropping in a buffer tank of a coating machine. Background Art

[0002] In the existing coating buffer tank, when the slurry flows into the buffer tank, the slurry is affected by the material pressure and sprayed out from the feed port. The slurry falls under the action of gravity, and when it falls and contacts the slurry in the tank, it splashes and brings air in to cause bubbles. The existing buffer tank lacks the function of suppressing the generation of bubbles, which affects the production effect. Utility Model Content

[0003] The utility model aims to solve the problem of the existing coating buffer tank that when slurry flows into the buffer tank, the slurry in the tank splashes and brings air into the buffer tank to cause bubbles, thus affecting the production effect.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A coating machine buffer tank material drop bubble suppression mechanism, characterized in that: comprising a coating buffer tank, the coating buffer tank upper end side wall is provided with a feed inlet, the feed inlet is connected to a guide component for guiding the injected slurry;

[0006] The flow guide assembly includes a feed pipe, the discharge end of the feed pipe is detachably connected to an insertion pipe, the insertion pipe is connected to the feed port and extends into the coating buffer tank, one end face of the insertion pipe extending into the coating buffer tank is closed, and the bottom surface of one end face of the insertion pipe extending into the coating buffer tank is provided with a flow guide port, and the flow guide port is connected to a flow guide pipe extending downward;

[0007] The guide tube includes a back guide plate, one end of which extends upward into the guide port and is connected to a closed end surface of the guide tube, the lower end of the back guide plate extends downward from the guide port and is connected to an inclined guide plate, the inclined guide plate is inclined toward the inner wall of the coating buffer tank at one end of the feed inlet, and the lower end of the inclined guide plate extends downward and is connected to a straight guide plate.

[0008] A further improvement is that side baffles are provided at the front and rear ends of the back guide plate, the inclined guide plate and the straight guide plate.

[0009] A further improvement is that: a first butt flange is provided at the connection end between the feed pipe and the insertion pipe, and a second butt flange is provided at the connection end between the insertion pipe and the feed pipe.

[0010] A further improvement is that the feed pipe and the insertion pipe are connected and fixed by means of a first butt flange and a second butt flange with matching bolts.

[0011] A further improvement is that a sealing ring is provided at the joint between the first butt flange and the second butt flange.

[0012] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0013] Through the guide pipe, the slurry flows along the back guide plate, inclined guide plate and straight guide plate of the guide pipe and flows to the inner wall of the buffer tank. Due to the viscosity of the slurry, it interacts with the tank wall to slow down the descent speed of the slurry. The slurry falls slowly against the tank wall and finally flows into the bottom of the tank, avoiding the splashing of air bubbles brought in by the falling slurry caused by the pressure and weight of the material when it contacts the slurry in the tank. The straight guide plate increases the diversion protection when the slurry falls straightly to reduce the outward splashing. BRIEF DESCRIPTION OF THE DRAWINGS
