According to the slurry sieving and de-foaming device, the vacuum box is vacuumized and slurry in the trough is agitated, so that air bubbles in the slurry can be sufficiently exposed in vacuum to be effectively removed and the yield of a coating procedure is improved; the slurry sieving and de-foaming device has the remarkable effect of removing air bubbles generated in a process of conveying slurry to the coating machine head from a slurry mixing machine, the vacuum sieving is realized, and the slurry sieving efficiency is greatly improved.
Description
Technical field
The utility model belongs to lithium ion battery production equipment field, is specially a kind of slurry that is installed on coater head and sieves and defoaming device.
Background technology
Pulp of lithium ion battery can produce bubble in homogenate and course of conveying, if can not in time these bubbles be eliminated, can cause the pole piece being coated with out to reveal paper tinsel, dry linting, qualification rate to painting process makes a big impact, especially negative pole reveals paper tinsel and can cause battery negative terminal surface in cyclic process to produce Li dendrite, and then pierces through barrier film and cause internal short-circuit of battery; Dry linting not only can make the volume lowering of battery, and may cause self-discharge of battery bigger than normal.In prior art, the froth breaking of slurry generally all vacuumizes realization by involutory pulp grinder and turnover barrel.There is no special concern by closing pulp grinder or turnover barrel to the bubble producing in coater head course of conveying for slurry.In addition, current lithium ion battery production technology adopts normal pressure to sieve conventionally, and screening efficiency is lower.
Utility model content
The purpose of this utility model is to provide a kind of slurry that is installed on coater head to sieve and defoaming device, not only can eliminate the bubble in slurry, and has improved the efficiency that slurry sieves.
The purpose of this utility model can be achieved through the following technical solutions:
The slurry that is installed on coater head sieves and a defoaming device, comprises the paint roller, back flow roll, the rotor that are located at hopper one side, and described hopper is located in vacuum tank, and agitating device is installed in hopper, is provided with the platform for placing screen cloth directly over hopper.
Described vacuum tank covers hopper completely and is connected with rotor with paint roller, the top margin that the base of described platform is vacuum tank.
Described agitating device is the helical structure that is parallel to hopper, and agitating device one end is provided with motor, and agitating device is fixed on the baffle plate of hopper.
Described platform is parallel to hopper, and platform bottom surface is 20-40cm apart from the vertical height of hopper.
Described platform middle has circular hole, and circular hole is up big and down small structure, and described screen cloth is stuck among circular hole, and the upper diameter of described circular hole is 1.02-1.1 times of screen cloth diameter, and lower diameter is 0.90-0.96 times of screen cloth diameter.
Described vacuum tank one side is connected with vacuum tube, and vacuum tube is provided with vacuum meter.
Directly over described screen cloth, be provided with feeder sleeve.
The beneficial effects of the utility model:
1, by vacuum tank being vacuumized and the slurry in hopper being stirred, bubble in slurry can be exposed in a vacuum fully, can effectively remove the bubble in slurry and improve painting process qualification rate, from closing pulp grinder to the bubble producing coater head course of conveying, act on especially obvious to slurry.
2, realize vacuum and sieved, greatly improved the screening efficiency of slurry.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is that schematic diagram is looked on a left side for the utility model structure.
Fig. 2 is the front elevational schematic of the utility model structure.
In figure, 1-paint roller, 2-back flow roll, 3-rotor, 4-feeder sleeve, 5-platform, 6-circular hole, 7-screen cloth, 8-vacuum tank, 9-hopper, 10-agitating device, 11-motor, 12-vacuum tube, 13-vacuum meter.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of slurry that is installed on coater head sieves and defoaming device, this device is included in the vacuum tank 8 that coater head arranges, and is located at paint roller 1, back flow roll 2, the rotor 3 of hopper 9 one sides, and vacuum tank 8 covers hopper 9 completely and joins with paint roller 1 and rotor 3.Agitating device 10 is installed in hopper 9, and it drives by motor 11.Be parallel to hopper 9 and be provided with platform 5 apart from hopper 9 vertical height 20-40cm places, platform 5 bases are as the top margin of vacuum tank 8.Platform 5 centers have circular hole 6, and the upper diameter of circular hole 6 is 1.02-1.1 times of screen cloth 7 diameters, and lower diameter is 0.90-0.96 times of screen cloth 7 diameters.Screen cloth 7 can be stuck among circular hole 6 like this.
When production, first open the valve of feeder sleeve 4, slurry is defeated to be flow on screen cloth 7, starter motor 11, agitating device 10 is started working, and then opens the valve of vacuum tube 12, whole vacuum tank 8 is interior starts to form vacuum, and the size of vacuum shows by vacuum meter 13, regulates by vacuum valve.By the stirring of agitating device 10, the bubble in slurry is constantly brought to pulp surface, is exposed in vacuum, is eliminated.In addition, due to the interior vacuum that formed of vacuum tank 8, and screen cloth 7 bottoms are communicated with vacuum tank, and the velocity ratio that slurry sieves is depended merely on gravity and sieved and greatly accelerate.Under certain feed flow, we can adjust slurry defoaming effect and velocity through screen by the size of adjusting vacuum tank 8 interior vacuums simultaneously, very convenient.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
