Technical Field

The invention relates to the technical field of solution filling systems, in particular to an automatic exhaust valve of a solution precision filling system.

Background

In the chemical production industries such as lithium battery processing, a solution is one of the most common raw materials, and the control of the filling amount of the solution has a great influence on the quality of a product, so that a solution filling system is started, but gas in a pipeline of the solution filling system needs to be discharged in time so as to avoid entering a container to influence materials, and mechanical exhaust is commonly used at present, and the measurement precision is influenced when the exhaust process lasts for the whole filling stage.

Disclosure of Invention

In order to solve the problem that the metering precision is influenced because the exhaust time lasts the whole filling stage in the prior art, the invention provides the automatic exhaust valve of the solution precision filling system, which can shorten the exhaust time, avoid exhaust in the filling process and improve the solution metering precision.

The technical scheme is as follows: the utility model provides an automatic vent valve of solution precision filling system, its includes the inlet conduit, inlet conduit end connection filling pipeline and exhaust duct, exhaust duct connects exhaust apparatus, a serial communication port, exhaust apparatus includes pneumatic ball valve, pneumatic ball valve one end is connected exhaust joint is connected to exhaust duct, the other end, be provided with the sleeve in the exhaust duct, be provided with the flotation pontoon in the sleeve, the fixing base is connected at the sleeve top, exhaust through-hole has been seted up in the fixing base, the flotation pontoon top be provided with exhaust through-hole complex apex piece, install the inductive head on the apex piece, install on the fixing base with inductive head complex sensing mechanism, sensing mechanism with pneumatic ball valve is automatically controlled to be connected.

The induction head is a magnet, and the sensing mechanism is a magnetic switch.

After the invention is adopted, the solution enters the sleeve of the exhaust pipeline, when the buoyancy of the solution to the buoy enables the buoy to float to the limiting position, the sensing mechanism senses the signal of the sensing head to close the pneumatic ball valve for exhaust, and at the moment, no exhaust is generated in the filling process, so that the solution metering precision is improved.

Detailed Description

See fig. 1, an automatic exhaust valve of solution precision filling system, it includes inlet conduit 1, 1 end connection filling pipeline 2 of inlet conduit and exhaust duct 3, exhaust duct 3 connects exhaust apparatus 4, exhaust apparatus includes pneumatic ball valve 5, exhaust duct 3 is connected to 5 one ends of pneumatic ball valve, other end connection exhaust joint 6, be provided with sleeve 7 in the exhaust duct 3, sleeve 7 is fixed in exhaust duct 3 through sleeve base 8, be provided with flotation pontoon 9 in the sleeve 7, fixing base 10 is connected at the sleeve 7 top, exhaust through-hole 11 has been seted up in the fixing base 10, flotation pontoon 9 top is provided with top piece 12 with exhaust through-hole 11 complex, install magnetite 14 on top piece 12, install on the fixing base 10 with magnetite complex magnetic switch 13, magnetic switch 13 is connected with pneumatic ball valve 5 is automatically controlled.

The working principle is as follows: liquid is introduced into the liquid inlet pipeline 1, the liquid enters the exhaust pipeline 3, the pneumatic ball valve 5 is opened at the moment, the control valve arranged on the filling pipeline 2 is closed, gas in the pipeline is exhausted from the exhaust joint 6, at the moment, in the exhaust stage, the floating cylinder 9 floats upwards under the action of buoyancy along with the rise of the liquid level of the solution continuously entering the sleeve 7, the floating cylinder moves upwards until the top tip block 12 floats upwards to move to the position of the magnetic switch 13, the magnetic switch 13 sends a feedback signal to the pneumatic ball valve 5 after receiving a magnet 14 signal, the pneumatic ball valve 5 is closed, the exhaust is stopped, and the solution filling stage is entered.
