Technical Field

The utility model relates to a high-efficient energy-conserving dustless powder feeding device for there is the production process of powder vacuum feeding, promotes the feeding efficiency and the effect of powder.

Background

Relates to a production process of vacuum feeding of powder, wherein the powder is fed into a powder trough by manual feeding and then is sucked into a dispersion tank in vacuum. In this process, there are three problems.

Firstly, dust is generated in the manual powder feeding process, a dust remover needs to be additionally arranged, otherwise, a large amount of dust is sucked by a human body, and the health of workers is harmed;

secondly, some powder materials have poor fluidity, cannot flow quickly during vacuum material suction, and need manual intervention;

thirdly, because the vacuum suction is great, the powder can be partially sucked into the vacuum buffer tank or even the vacuum pump after entering the dispersion tank, which not only causes the waste of raw materials, but also affects the service life and the use effect of the vacuum pump, thereby affecting the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high-efficiency energy-saving dust-free powder feeding device, the whole set of device can effectively improve the feeding environment and the feeding efficiency; the material loss can be effectively reduced, the equipment failure rate is reduced, and the production continuity is ensured.

The utility model discloses the purpose is reached through following measure: the design is a high-efficiency energy-saving dust-free powder feeding device which comprises a vacuum buffer tank, a vacuum pump, a dispersion tank, a dust-free feeding station, a control box, a flowmeter, an automatic valve and the like. The method is characterized in that: the dust-free feeding station is positioned on one side below the dispersion tank, is communicated with the lower end enclosure of the dispersion tank through a closed pipeline, and controls feeding through a pneumatic valve and a control box; the upper end enclosure of the dispersion tank is connected with a vacuum buffer tank; the buffer tank is connected with a vacuum pump and a flowmeter, and the flowmeter is used for metering water inflow. The opening and closing of the flowmeter and the vacuum pump and the opening and closing of the automatic valve are controlled by the control box. During production, the powder is manually fed into a dust-free feeding station, and the vacuum degree and the feeding valve are mutually interlocked under the control of a control box. Under the vacuum action, the powder is sucked into the dispersion tank and mixed with the liquid material, but partial powder is sucked into the vacuum buffer tank under the vacuum action, the water inlet valve is opened at the moment, the powder on the inner wall of the buffer tank is washed by the metered water, and the washed material automatically flows back to the dispersion tank.

The utility model discloses compare with advance powder device in the past, beneficial technological effect lies in:

1. the device adopts the dust-free feeding station integrating dust removal and vibration, the feeding is carried out in a closed space, the generated dust is immediately recycled by the dust remover, no dust flies during feeding, and the health of workers can be effectively guaranteed. The feeding station is provided with a vibration motor, so that the flow of powder can be effectively promoted, manual stirring is not needed, and the feeding efficiency is improved.

2. The novel vacuum backflow process is adopted, powder sucked away by vacuum is flushed back to the dispersion tank again by the formula water, so that pollution of the powder to the vacuum pump is avoided, material loss is reduced, and product quality is effectively guaranteed.

Detailed Description

As shown in figure 1, the dust-free feeding station 1 integrates a dust removal device 2 and a vibrator 3, and is communicated with a feed inlet at the bottom of a dispersion tank 5 through a powder inlet pipe 4 and a 1# automatic valve 6, wherein the 1# automatic valve 6 is used for controlling feeding, and the opening and closing of the feeding station are automatically controlled through a control box 14. The bottom of the vacuum buffer tank 7 is communicated with the upper end enclosure of the dispersion tank 5 through a vacuum tube 10. The upper end socket of the vacuum buffer tank 7 is connected with a vacuum pump through a vacuum pipe 10 and a vacuum automatic valve 13, and is connected with a flowmeter 9 and a No. 2 automatic valve 12 through a water inlet pipe 11. The flow meter 9 and the # 2 automatic valve 12 are automatically controlled by a control box 14.

The use process of the device is as follows: powder is firstly put into the dust-free feeding station 1 from the side, the dust removal device 2 is automatically started, and dust generated inside is quickly sucked away. Then the vacuum pump 8 and the control box 14 are opened, the vacuum automatic valve 13 is automatically opened, the automatic valve 6 # 1 is automatically opened after negative pressure is formed inside the dispersion tank 5, powder enters the dispersion tank 5 under the action of vacuum, and the vibrator 3 of the dust-free feeding station 1 is automatically opened, so that the powder is promoted to be fed quickly, and the powder in the station is prevented from playing a bridge. After the powder is fed, the control box 14 controls the automatic closing vacuum pump 8 and the # 1 automatic valve 6.

The automatic valve No. 1 6, the automatic valve No. 2 12 and the vacuum automatic valve 13 are all connected with the control box 14, the automatic valve No. 1 6 and the vacuum automatic valve 13 are mutually interlocked, and the opening and closing of the vacuum pressure control valve are used for preventing the material from flowing backwards.

Because the vacuum force is large, partial powder is sucked into the vacuum buffer tank 7, the automatic valve No. 2 12 is opened through the control box 14 at the moment, the formula water enters the vacuum buffer tank 7 through the flowmeter 9, and the powder in the vacuum buffer tank 7 is washed; after the water reaches the preset amount, the control box 14 controls the automatic 2# valve 12 to close automatically. The washed powder automatically flows back to the dispersion tank 5.
