But, existing coating machine feeding system exists following drawback: contain rotatable parts in (1) operated pneumatic valve, rotatable parts cooperate with phenyl tetrafluoride pad, in the process of using, make the wearing and tearing between rotatable parts and the phenyl tetrafluoride pad aggravate because slurry flows in valve, so that operated pneumatic valve damage especially easily in the use of one or two month.(2) maintenance work after operated pneumatic valve damages is also very difficult, needs all dismountings maintenance more later on; , leakage also usually poorly sealed through the operated pneumatic valve after repairing expected serious, causes the liquid surface height controlling instability, causes the coating quality instability of pole piece.(3) when the sealing of transporting the slurry dolly is good inadequately, slurry in the car can be pressed among the slurry tank in order to guarantee to transport the slurry dolly, just need to strengthen compressed-air actuated air pressure, and fortune slurry dolly has a maximum to bear force value, surpass the possibility that this pressure fortune slurry dolly has explosion, the security of fortune being starched dolly impacts.When (4) slurry in fortune slurry dolly soon fans the air, by reason of heavy pressure and slurry is few, will cause material spray in slurry tank, and around can being sprayed onto, influence the healthy of workshop condition and staff.
The utility model content
The technical problems to be solved in the utility model provides a kind of shortcoming that can overcome existing coating feeding system, stably to the slurry tank feeding, the danger that overcomes injecting compressed air in fortune slurry dolly and cause, the possibility of material spray when avoiding transporting slurry in the slurry dolly and soon fanning the air, avoid on pole piece, forming particle, cut simultaneously, and can remove the novel coating feeding system of iron material.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of novel coating feeding system, comprise fortune slurry dolly, the port of export of described fortune slurry dolly connects the arrival end of pneumatic diaphragm pump, and the port of export of described pneumatic diaphragm pump connects the arrival end of iron removal by filtration system, and the port of export of described iron removal by filtration system is connected with slurry tank; Be provided with the blowout prevention sensor between the outlet of described fortune slurry dolly and the arrival end of pneumatic diaphragm pump.
Described iron removal by filtration system comprises the filter that is provided with screen pack.
Described filter is provided with Pressure gauge.
The order number of described screen pack is 100 orders/m
2～200 orders/m
2
The beneficial effects of the utility model are:
(1) extracts slurry by pneumatic diaphragm pump and carry, avoided operated pneumatic valve poorly sealed and the possibility of leaking material is more stable to the slurry tank feeding.
(2) even if damaged condition appears in pneumatic diaphragm pump, also only need the parts of dismounting minority to keep in repair, and each parts of pneumatic diaphragm pump can buy easily on market, keep in repair more convenient.
(3) owing to be not transport the slurry of starching in the dolly by compressed air to carry out feeding among being pressed into slurry tank, starch the situation generation that the dolly maximum is born force value so also do not have pressure above fortune, overcome the danger of starching injecting compressed air in the dolly and causing to transporting.
(4) owing between fortune slurry dolly and pneumatic diaphragm pump, be provided with the blowout prevention sensor, when the slurry polishing soon in the fortune slurry dolly, sensor can send signal to be stopped pneumatic diaphragm pump being carried out air feed, the possibility of material spray when the avoiding of success transported the slurry of slurry in the dolly and soon fanned the air.
(5) setting of filter can filter out bigger sauce particle, avoids forming on pole piece particle, cut.
(6) setting of high deironing device can be adsorbed the iron material in the slurry, has improved the security performance of battery.
