[0018] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0019] Referring to Figs. 1-3 A solid feeding device, comprising a bin 6 for containing powdery solid material, which is designed reasonably and has moderate capacity to meet the production requirement; a hopper 3 for facilitating feeding operation is installed at the top of the bin 6, which is designed in shape to facilitate feeding operation, so that the worker can easily pour the powdery solid material into the hopper 3; the hopper 3 is installed on the bin 6 through a vertically arranged material pipe 5, which not only ensures that the powder can smoothly enter the bin 6, but also reduces the waste and leakage of the powder during the feeding process;

[0020] A wire grid 1 for playing a safety role is installed at the joint of the hopper 3 and the material pipe 5, which is made of aluminum pipe network. This material is not only light and durable, but also has good electrical conductivity. The aluminum pipe network is made of several aluminum pipes, and the signal line is worn in the aluminum pipe. Such design not only protects the signal line from being abraded by the powder, but also ensures the stability of signal transmission; the wire grid 1 is provided with rectangular openings, which not only do not affect the normal feeding of the powder, but also effectively prevent large pieces of powder or foreign matters from entering the material pipe 5, thereby ensuring the safety of the feeding process;

[0021] A rotary valve 12 for cooperating with the input of the powdery solid material is installed at the joint of the material pipe 5 and the bin 6, which facilitates uniformly conveying the powdery solid material into the bin 6 according to the requirement. The rotation speed of the valve can be adjusted to realize the accurate control of the powder flow, thereby meeting the requirement of quantitative conveying.

[0022] A hole plate 4 for filtering the powdery solid material and control valves I 9 and II 11 for switching control of the material pipe 5 are sequentially installed in the material pipe 5 from top to bottom, a feeding gap is left between the hole plate 4 and the wire mesh 1, a material level meter I 7 is further installed on the material pipe 5 at the feeding gap, a discharging gap is left between the control valve I 9 and the control valve II 11, and a material level meter II 10 is further installed on the material pipe 5 at the discharging gap. The main function of the hole plate 4 is to filter the powdery solid material, remove impurities or large pieces of powder in the powdery solid material, and ensure the quality of the powder entering the bunker 6; the control valves I 9 and II 11 can realize accurate control of the powder in the material pipe 5, when the material level meter I 7 detects that the powder accumulates to the set position, the control valve I 9 is opened for discharging; when the material level meter II 10 detects that the powder falls to the set position, the control valve I 9 is closed and the control valve II 11 is opened to continue the discharging process. This control method not only improves the production efficiency, but also ensures the stable flow of the powder in the material pipe 5; preferably, the control valves I 9 and II 11 are automatic valves.

[0023] Preferably, the material pipe 5 is in a cylindrical shape, which not only facilitates the flow of the powder, but also reduces the friction and resistance of the powder in the material pipe 5; the wire mesh 1 and the hole plate 4 are both in a disc shape, which matches the shape of the material pipe 5, ensuring that they can be tightly installed on the material pipe 5, thereby improving the stability and safety of the device.

[0024] In order to realize the automatic operation of the entire device, further improve the safety, the device further comprises a control box, a controller 8 is installed in the control box, a signal line is connected to the input end of the controller 8 through the signal indicator 2, the material level meter I 7 and the material level meter II 10 are both connected to the input end of the controller 8, the rotary valve 12, the control valve I 9 and the control valve II 11 are all connected to the output end of the controller 8, which facilitates the controller 8 to accurately control the rotary valve 12, the control valve I 9 and the control valve II 11 by receiving the signals transmitted by the signal line and the material level meter, and a control button cooperating with the controller 8 is further installed on the control box, which facilitates the input of instructions to the controller 8; specifically, the controller 8 can be a PLC controller 8 or a CPU controller 8, and the specific internal control program thereof can be programmed by those skilled in the art using existing programs, which can meet the requirements of the present application.

[0025] The working principle of the solid feeding device provided by the present application is as follows:

[0026] Before the powder is added, the control valve I 9 is in an open state, the control valve II 11 is in a closed state, and the rotary valve 12 is in a stopped state;

[0027] When the material level meter I7 detects that the material is full, the control valve I9 is closed, the rotary valve 12 is started by the controller 8, and the control valve II 11 is opened. When the powder in the material pipe 5 is completely discharged into the hopper 6, the material level meter II 10 detects that the material pipe 5 is empty, and the rotary valve 12 and the control valve II 11 are closed;

[0028] During this period, the wire mesh 1 can block the falling woven bag to prevent it from falling into the hopper 6. At the same time, if the woven bag falls onto the wire mesh 1, the operator can safely take it out. Secondly, if an accident occurs, such as the operator being pulled into the hopper 3 and falling onto the wire mesh 1, the wire mesh 1 will deform due to excessive force, and the signal wire in the wire mesh 1 will break, thereby sending a signal to the controller 8 through the signal device 2. The controller 8 receives the signal and immediately controls the rotary valve 12 to stop running. The signal can also be transmitted to the external package host computer through the communication module, effectively playing a passive distress role and ensuring safety.

[0029] In this way, the safe feeding of powdery solid materials can be realized.
