8 Features of HUAYUN complete automatic paint production line

Feature 1 : Fully Closed Production Process

　　Fully closed production process has been adoptedto the automatic integration coating complete equipment.No leakage of dust pollution and organic solvent, thus it saves the loss of leakage and will not cause the air pollution. Production process is automatic intelligentized. Efficiency and quality are highly improved by monitoring and recording process regularly, adopting computermanagement model.
 

Feature 2 :Feeding The Material From The Tank Base

　　Feeding the material from the base by vacuum pressure makes the short feeding distance and feeding speed quickly.It avoid backflow and excavation which might happen if dothis job by labor. The material is surrounded by water after entering in the tank, this avoid the powder pollution into the air and blocking at the feeding port. It can feed 500kgs material to the tank within 2 min and keep the performance constantly. Traditional way is to feed material from the top of tank, It will take 25min to complete the same job, and the material is easy to adhere to the tank inwall causing the loss of material.

Feature 3: Double Layers Dispersing Disc

　　The key part of the complete equipment is the disperser and the key part of disperser is dispersing disc. Thus, Dispersing disc is very important to improve the dispersing efficiency. Double layer dispersing disc was adopted high wear-resistance material with high shear capacity and high speed. Efficiency of double dispersing disc is several times more than traditional type.

Feature 4: Fully Closed Manhole

　　The complete equipment requires transferring with vacuum pressure. If there is leakage point on the tank,the complete equipment will not work. We install the Sealing silicone on the cover of manhole, this operation avoids the material to contact with manhole cover making the sealing performance much better.

Feature 5: HMI、Automatic Production

Microcomputer interface technique and automatic online monitoring are adopted to the production process. Material can be weighed automatically and precisely
 

Feature 6: Mechanical Sealing With Cooling Water

　　Traditional way is to use open mixing tank and feed material by labor. This way causes serious dust pollution. We adopts fully closed production process , feed material with vacuum pressure, and install the disperser in the tank, this way avoid dust pollution. High speed disperser is equipped with mechanical sealing with cooling water 、NSK bearings、flexible coupling、etc ,which ensures the quality and make it easy to do maintaining job.
 

Feature 7: High-precisionColor Mixer

　　The color mixing processcontrolled by computer, avoids the cleaning of huge tanks, saves labor and time, improves the efficiency and achieves zero release. Automatically select, measure and inject, high automation, easy operation and simple maintenance. The packing tank position controlled by photoelectric sensor, more precise and reliable.
 

Feature 8: Recoil/bag Filter

　　Automatically remove the particulate impurities on the surface of the filter element through an efficient mechanical cleaning method, capable of on-line continuous filtration in a single machine, with an accuracy range of 25-3000 μm, without producing filter consumables, No need for frequent manual cleaning.

1. The straight-line reciprocating type removes impurities directly from the surface of the filtere lement.

2. The shaft seal adopts upper and lower two seals, good sealing effect, the disassembly and replacement are convenient.

3. On-line continuous filtration, automatic operation, end the heavy works of filter replacement and cleaning.

4. Less the filter pressure loss, flow is stable, reducing pipeline energy consumption, conducive to continuous and stable process.

5. Closed filter to prevent leakage of dangerous materials, which is conducive to the safe production.

Composition of complete automatic paint production line

Emulsion Feeding System

1.Emulsion Feeding Tank

　　The emulsion is transported by the tank truck into the plant and then pumped into the emulsion tank through a diaphragm pump

2.Emulsion Weighing

　　A. Set the amount of emulsion by computer. When it is required to enter the emulsion, the pneumatic valve for feeding the weighing tank is opened, and the corresponding diaphragm pump is interlocked .The emulsion is pumped into a weighing tank for weighing.

　　B. The computer controls the weighing tank. When the weight reaches the required amount of the formula, the feeding pneumatic valve automatically closes, the diaphragm pump chain closes, and the feeding stopped.

3.Emulsion Feeding Emulsion Feeding

　　Open the discharge pneumatic valve of weighing tank and feeding pneumatic valve of production tank , open the vacuum valve at the same time, and inhale the already weighed emulsion into the production tank by vacuum.
 

Additives Feeding System

1. Additives Loading

　　A. Additives storage tanks are equipped with a hydraulic meter and connected to a computer. When the liquid level in the tank is lower than the minimum level, sound and light alarms, indicating feeding. B. Open the vacuum pneumatic valve for vacuum. After opening the manual valves, inhale the additives agent into the additives storage tank. C. When the liquid level in the tank reaches the upper limit level, sound and light alarms, the vacuum pneumatic valve closes, and the manual valve is manually closed.

2.Additives Weighing And Calculations

　　Pressurize the additives storage tank, open the weighing tank feeding valve, and control the weight in the weighing tank through the computer. When the set weight is reached, the feeding pneumatic valve will automatically close.

3.Additives Feed

　　The additives is sucked into the production tank with negative pressure by vacuum.
 

Water Treatment Process

 

1.Reverse Osmosis Treatment

　　The tap water is treated by a reverse osmosis device before production, it is put into a pure water storage tank for storage and stand by after reaching the production standard,.

2.Cleaning Water

　　A. The part of pure water in the formula can be used to clean the residual liquid material in the liquid material weighing tank and pipeline to improve the weighing accuracy.
