Embodiment 4
Cooling feed bin 4 can be replaced with weight calculation cooling feed bin 4 ', as shown in figure 19, weight calculation cooling feed bin 4 ' and cooling feed bin 4
The difference compared is：With weighing machine 47 ', feed bin body is connected with weighing machine 47 ', in other words, cools down feed bin body
41 bottom plate is the weighing unit of weighing machine 47 ', and bottom plate is equipped with teflon plate, makes that it is suitable for larger useless of viscosity
Paint slag；Inlet air web plate 412 ' is arranged on the left and right sides of body.
The weighing unit of weighing machine 47 ' and the bottom plate of feed bin body are combined into one, and weighing apparatus 47 ' are additionally provided with panel, it is set
On feed bin body 41, panel is equipped with different button and display, is realized by the operation of counter plate to weight calculation cooling material
Waste paint slag is weighed in storehouse, and obtains reading in the display.As shown in figure 20, its be weighing machine panel structure diagram,
Include on panel：Tare weight metering button 471 ', gross weight metering button 472 ', net weight metering button 473 ', net weight adds up button
474 ', reset button 475 ', return push-button 476 ', the first display 477 ', second display 478 ', the 3rd display 479 ',
4th display 4710 '.
Weight calculation cools down feed bin weighing process：When weight calculation cooling feed bin be also not added with waste paint slag when, press tare weight metering by
Button 471 ', shows corresponding weight on the first display 471 '；Cooled down to weight calculation in feed bin and add waste paint slag, when waste paint slag adds
After, gross weight metering button 472 ' is pressed, corresponding weight is shown in second display 478 '；Press net weight metering button
473 ', net weight is calculated, the weight of waste paint slag in the display net weight in the 3rd display 479 ', i.e. weight calculation cooling feed bin；Press net
Add up button 474 ' again, add up net weight, the accumulative net weight of display in the 4th display 4710 '；If measuring again, by reset button
475 ' are zeroed out；If not keeping a record, simply simply weigh, it is not necessary to press any button, the first display 477 ' is shown
The weight weighed.During weight calculation cools down feed bin use, if it is excessive to be put into the waste paint slag that need to be cooled down, cooling effect can be reduced,
Cause waste paint slag internal cooling uneven, if it is very few to be put into waste paint slag, use cost can be wasted.By the title for counting weight cooling feed bin
Weight function, calculate net weight function, accumulating function, can be very good control cool down every time waste paint slag number, effectively improve weight calculation
Cool down the work efficiency of feed bin.
The cooling procedure of weight calculation cooling feed bin 4 ' is identical with cooling feed bin 4.
It these are only the preferred embodiment of the utility model, be merely illustrative for the utility model, rather than limit
Property processed.Those skilled in the art understands, it can be carried out in the spirit and scope that the utility model claims are limited
Many changes, modification, in addition it is equivalent, but fall within the scope of protection of the utility model.
