Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to an automatic tilting feeding vehicle. Background Technology

[0002] In the preparation of cemented carbide, metal powders such as tungsten carbide and cobalt are typically used as the main raw materials, supplemented by volatile organic solvents as dispersion media and lubricants during wet milling, thereby ensuring product quality in subsequent pressing and sintering stages. A typical preparation process includes raw material proportioning, mixing, wet milling, drying, forming, and sintering, among which material preparation and feeding before wet milling are key steps.

[0003] In existing technology, operators must first add metal powder and metered volatile organic solvents sequentially to a mixing tank. After mixing, the mixing tank is manually moved to the wet grinding mill station, and the opening of the tank is manually aligned with the raw material inlet of the wet grinding mill before the material is poured out. However, volatile organic solvents are highly volatile and are prone to evaporation and spillage during the pouring process. Their vapors can directly harm the operator's respiratory and nervous systems and pose flammable and explosive safety hazards. In addition, the mixing tank often contains a certain weight of material, and manual handling and alignment require a lot of physical strength and it is difficult to ensure the docking accuracy. This not only leads to low feeding efficiency but may also cause material waste due to spillage, affecting the continuity of production.

[0004] Therefore, it is of great significance to develop an automated device that can avoid human intervention, reduce the volatilization of volatile organic solvents, and improve feeding efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of organic solvent evaporation and potential health hazards, as well as low feeding efficiency, during the feeding process of wet grinding mills in the preparation of cemented carbide. This invention provides an automatic tilting feeding cart that avoids manual intervention, reduces organic solvent evaporation, and improves feeding efficiency.

[0006] This utility model provides an automatic tilting and feeding cart, including a frame, a material bin mounted on the frame, and a drive mechanism; The vehicle frame is equipped with a track lifting mechanism, and the mixing barrel can be vertically lifted and tilted and flipped along the track lifting mechanism under the action of the drive mechanism. The mixing tank is equipped with a filling port, which is used to add organic solvents into the mixing tank.

[0007] This utility model's automatic tilting and feeding trolley, through the coordinated action of the drive mechanism and the track lifting mechanism, automatically lifts and tilts the batching hopper, achieving precise sealing and connection between the hopper outlet and the raw material inlet of the wet mill. The fully enclosed automated operation effectively avoids the volatilization of volatile organic solvents (such as hexane), eliminating flammable and explosive safety hazards and health risks to operators from volatile organic solvent gases, significantly improving operational safety. It replaces heavy manual operation, reducing labor intensity, and ensures feeding efficiency and continuity through precise docking. Furthermore, during use, powder is first added to the batching hopper, and organic solvent is added through the filling port during the lifting and tilting process or when unloading from the wet mill, effectively improving feeding safety. The washable batching hopper ensures that all materials in the hopper are thoroughly rinsed before entering the wet mill. Finally, this utility model's trolley structure is simple, highly applicable, and easy to promote and apply.

[0008] As a preferred embodiment of this utility model, the sidewalls of one or both sides of the mixing tank have a smooth transition structure with the discharge port of the mixing tank. The smooth transition structure is selected from large rounded corner transition, inclined surface transition or parabolic transition, which can effectively avoid material residue and has no dead corners. When the mixing tank is turned over for feeding, it can better achieve emptying.

[0010] Preferably, the discharge port of the mixing tank is equipped with a quick-connect flange, which enables a rapid sealing connection.

[0011] As a preferred embodiment of this utility model, the flexible sealing element is an O-ring.

[0012] As a preferred embodiment of this utility model, a control valve for controlling the discharge of materials is provided at the discharge port.

[0013] As a preferred embodiment of this utility model, a cleaning mechanism is provided inside the mixing tank, and the cleaning mechanism is connected to the filling port. The cleaning mechanism can use a volatile organic solvent (such as n-hexane solvent) to clean the material adhering to the mixing tank. More preferably, an automatic metering device is connected to the filling port.

[0014] As a preferred embodiment of this utility model, the cleaning mechanism is a rotary spray mechanism.

[0015] As a preferred embodiment of the present invention, the track lifting mechanism includes two first tracks and two second tracks arranged opposite to each other; the first tracks are vertical lifting tracks; the lower part of the second tracks is a vertical extension section and the upper part is a curved extension section.

[0016] Preferably, the vertical extension section and the curved extension section are arranged continuously.

[0017] Preferably, the vertical extension and the curved extension transition smoothly.

[0018] As a preferred embodiment of this utility model, the side of the mixing barrel is provided with a first connector and a second connector; the first connector is fixed to the barrel wall near the bottom of the mixing barrel and is rotatably connected to a flipping shaft, the two ends of the flipping shaft being respectively assembled in two oppositely arranged first tracks; the second connector is fixed to the barrel wall near the neck of the mixing barrel and is rotatably connected to a fixing shaft, the two ends of the fixing shaft being respectively assembled in two oppositely arranged second tracks.

[0019] As a preferred embodiment of this utility model, the driving mechanism includes a chain elevator and a chain; the chain elevator can drive the mixing barrel to move upward through the chain.

[0020] Furthermore, one end of the chain is connected to the tilting shaft, and the other end passes over a chain pulley located on the upper part of the frame and is connected to the chain hoist. Preferably, the chain passes over a fixed pulley at the top of the frame.

[0021] As a preferred embodiment of this utility model, the frame is mounted on a traveling mechanism, which can move back and forth to adjust the relative position of the mixing tank and the wet mill.

[0022] As a preferred embodiment of this utility model, the mixing tank is connected to an exhaust port, which is used to connect to an exhaust branch pipe, enabling the volatile organic solvents discharged from the wet mill and the mixing tank during the addition of volatile organic solvents (such as n-hexane) to be discharged into the waste gas recovery system. When the material to be ground is added, some waste gas flows out of the wet mill, or when organic solvents are added, some organic solvents evaporate to form waste gas. The waste gas is then drawn off through the exhaust outlet to prevent the waste gas from escaping and causing air pollution.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model's automatic tilting and feeding trolley, through the coordinated action of a drive mechanism and a track lifting mechanism, automatically lifts and tilts the batching hopper, achieving precise sealing and connection between the hopper outlet and the raw material inlet of the wet mill.
