Abstract

Disclosed in the present invention is an automatic vacuum powder feeding device from the bottom of a sealed container comprises a powder tank (1), a powder pipe (2), a pneumatic ball valve (3) and an automatic control box (4). The powder tank (1) is connected with the bottom of the container through the powder pipe (2), the pneumatic ball valve (3) is set at the bottom of the container, the control box (4) is provided next to the powder tank (1), and the container is connected with a vacuum bump (6) and equipped with a negative pressure vacuum meter (7). The switch parameter values of the pneumatic ball valve are set through the instrument of the control box, and the parameter values are related to the degree of vacuum in the container. After the degree of vacuum reaches a certain value, the signal of the negative pressure vacuum meter is transmitted to the instrument, the pneumatic ball valve is automatically opened and closed, and the powder is automatically sucked into the container. The device can reduce manual interference, avoid slurry backflow, evacuation and other phenomena caused by inaccurate manual operations, reduce labor intensity and powder loss, and improve production efficiency and product quality.

Description

Description: A vacuum automatic feeding device for a sealed container bottom

The utility model relates to a vacuum automatic powder feeding device for sealing a bottom of a container, in particular to a bottom vacuum automatic powder feeding device used in the chemical and coating industry. Background technique

In the existing paint production and powder feeding devices, most of them are manually operated valve control. If the manual operation is not timely, it will lead to the phenomenon of pumping, evacuation and slurry backflow, which will affect the next production process, even Affects product quality and equipment life. Utility model content

The purpose of the utility model is to improve the feed efficiency of the powder, improve the automation degree of the feed, reduce the manual intervention and material loss, and improve the production efficiency.

The purpose of the utility model is achieved by the following measures: Designing a vacuum automatic feeding device for the bottom of a sealed container, comprising a powder tank, a powder tube, a pneumatic ball valve, a solenoid valve and a control instrument, characterized in that: The tank is connected to the bottom of the sealed container through the powder tube, and the pneumatic ball valve is equipped with a solenoid valve to connect the control instrument to control the feeding, and the control instrument is arranged beside the powder tank. The switch parameter value of the pneumatic ball valve is set by the control box meter. The parameter value is related to the vacuum degree in the sealed container. After the vacuum degree reaches a certain value, the pneumatic ball valve is automatically opened and closed, and the powder material is automatically sucked into the container.

Compared with the conventional and prior art, the utility model has the advantages that: the powder enters from the bottom of the container, the feeding path is short, and the feeding speed is fast. The feed switch is automatically controlled, reducing manual intervention and avoiding It avoids the phenomenon of backflow and evacuation of the slurry due to improper manual operation. It saves manpower, reduces labor intensity, and improves production efficiency and product quality. DRAWINGS

The present invention will be further described below in conjunction with the accompanying drawings.

1 is a schematic structural view of a bottom vacuum automatic feeding device according to the present invention; wherein 1 is a powder tank, 2 is a powder tube, 3 is a pneumatic ball valve, and 4 is a control box.

5 is a sealed container, 6 is a vacuum pump, 7 is a vacuum negative pressure gauge, and 8 is an air hole. detailed description

As shown in Fig. 1, a feed port is arranged at the bottom of the container 5, the feed port is connected with the pneumatic ball valve 3, the powder tube 2 is connected with the pneumatic ball wide 3 through the quick connection; the powder tank 1 and the powder tube 2 are also connected by quick connection. Connected; an air hole 8 is opened every 1. 5 meters on the powder tube 2, and a small ball is assembled. Pneumatic ball valve 3 with solenoid valve Connect the control box 4 to control the feed. The control box 4 is placed next to the powder tank 1. The control box is equipped with a CPU, an AD conversion module and a button, and a negative pressure gauge 7 with a 485 signal is connected. The negative pressure gauge 7 is placed on the container head. The switch parameter value of the pneumatic ball valve 3 is set by the control box 4, and the parameter value is related to the vacuum degree in the container 5, and can be measured by the negative pressure gauge 7. The container 5 is connected to a vacuum pump 6, and is fed by a vacuum suction method. When the vacuum level drops to a certain value, the negative pressure gauge sends a signal to the CPU, and the pneumatic ball valve 3 automatically opens. When the vacuum is raised to a certain value after the material is sucked, the negative pressure gauge sends a signal to the CPU, and the pneumatic ball valve 3 is automatically closed. The switch parameter value can be set freely on the meter.

Automatic suction process: After the switch on the control box is selected in the "automatic position", when the negative pressure reaches the upper limit of the set value (-0. 08MPA, can be set), press the automatic suction button to start the automatic powder suction Expected At this time, the suction valve is opened. When the negative pressure reaches the set lower limit (such as -0. 02MPA, can be set), the suction valve is automatically closed. When the negative pressure reaches the upper limit of the set value again, Turn it on again, and the cycle operation will not reverse the slurry, and the powder can be continuously extracted. When the powder has been inhaled, press the "Auto Stop" button to exit the automatic working process. Automatic and manual operations can be switched to each other.
