A kind of zinc-plated pipe production line vacuum passivating solution sprayed coating device
Technical field
The utility model belongs to zinc-plated tubing processing units field, particularly a kind of zinc-plated pipe production line vacuum passivating solution sprayed coating device.
Background technology
Zinc-plated tubing finish zinc-plated after, all need corrosion stability, the aesthetic property of sprayed coating passivating solution to strengthen zinc-plated tubing.Mostly sprayed coating method in the past is to adopt the driven by motor water pump to carry out sprayed coating, and the method uses not only that equipment is many, consumes energy is large, and motor very easily damages with water pump, moves shakiness.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of zinc-plated pipe production line vacuum passivating solution sprayed coating device that equipment is few, energy charge is little, move that uses is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of zinc-plated pipe production line vacuum passivating solution sprayed coating device, it is characterized in that: formed by sprayed coating case, container for storing liquid, passivation flow container, vacuum tank, pneumatic controller, the sprayed coating case is installed on the zinc-plated tubing transfer limes, container for storing liquid is installed in sprayed coating case front end of the top surface, passivating solution is canned to be assigned in by the sprayed coating case side, vacuum tank is assemblied in the passivation flow container, and pneumatic controller is connected in the middle of air compressor and the vacuum tank.
And, described sprayed coating case, its rear end is shaped with the galvanized workpiece import, and its front end is shaped with the galvanized workpiece outlet, and its underpart is equipped with refluxing opening.
And, described container for storing liquid, its top is equipped with spillway, and its underpart is equipped with nozzle.
Advantage of the present utility model and beneficial effect are:
1. this zinc-plated pipe production line vacuum passivating solution sprayed coating device need not assemble motor, water pump, uses equipment few.
2. this zinc-plated pipe production line vacuum passivating solution sprayed coating device utilizes existing air compressor source of the gas, can reduce energy consumption.
3. this zinc-plated pipe production line vacuum passivating solution sprayed coating apparatus structure design science is reasonable, has the advantages such as use is equipped less, energy charge is little, stable, is a kind of zinc-plated pipe production line vacuum passivating solution sprayed coating device with higher innovation.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of zinc-plated pipe production line vacuum passivating solution sprayed coating device, formed by sprayed coating case 2, container for storing liquid 8, passivation flow container 10, vacuum tank 11, pneumatic controller 13, the sprayed coating case is installed on the zinc-plated tubing transfer limes, container for storing liquid is installed in sprayed coating case front end of the top surface, passivating solution is canned to be assigned in by the sprayed coating case side, vacuum tank is assemblied in the passivation flow container, and pneumatic controller is connected in the middle of air compressor and the vacuum tank.Sprayed coating case, its rear end are shaped with galvanized workpiece import 1, and its front end is shaped with galvanized workpiece outlet 7, and its underpart is equipped with refluxing opening 4.Container for storing liquid, its top is equipped with spillway 5, and its underpart is equipped with nozzle 6.
Principle of work of the present utility model is:
With passivating solution conduit 9 container for storing liquid is connected with vacuum tank, vacuum tank and pneumatic controller, air compressor is connected and sets the intermittent time of pneumatic controller with air-pressure duct 12.Start pneumatic controller, pressurized air enters vacuum tank by air-pressure duct, under the effect of vacuum tank, passivating solution enters from the passivating solution import of vacuum tank lower surface, flow out from the passivating solution outlet of vacuum tank upper surface, enter container for storing liquid through the passivating solution conduit, spray on the galvanized workpiece 3 through nozzle again; Drench lower passivating solution from galvanized workpiece, can be from the refluxing opening outflow of coating lower box part; When the passivating solution in the container for storing liquid is more, can overflow from spillway; Like this, a galvanized workpiece enters from the galvanized workpiece import that applies case, exports out from galvanized workpiece, namely finishes the passivating solution coating.
