Description

Technical Field

[0001] The utility model relates to the technical field of the production of film separating agents, in particular to a feeding mechanism for solid raw materials in the production of film separating agents. Background Art

[0002] When producing film separating agents, solid raw materials (solid raw materials of granular and powdery raw materials) and liquid raw materials need to be mixed in a stirring tank by a spiral stirrer. At present, solid raw materials (especially powdery raw materials) are very likely to agglomerate and form lumps. The lumps will cause the powdery raw materials to be unable to be evenly dispersed during the stirring process, and some granular solid raw materials are far less likely to participate in the stirring as well as the powdery raw materials. Whether it is the agglomerated raw materials or the granular solid raw materials, more energy is required to break the block structure, which will increase the difficulty of stirring, reduce the stirring efficiency, and it is very easy to have the phenomena of uneven distribution and agglomeration during stirring, affecting the product quality and the use effect of the product. Summary of the Utility Model

[0003] To solve the above problems, that is, to solve the problems raised in the above background art, the utility model provides a feeding mechanism for solid raw materials in the production of film separating agents, which includes a hopper, a grinding box, a connecting pipe and a blanking cylinder. The lower end of the hopper is fixedly communicated with the grinding box, the grinding box is connected to the blanking cylinder through the connecting pipe, the lower end of the blanking cylinder is fixedly communicated with a blanking pipe, and a grinding and feeding structure is installed in the hopper, the grinding box, the connecting pipe and the blanking cylinder;

[0004] The grinding and feeding structure includes a motor, a pair of inclined plates, an arc-shaped hole plate, grinding rollers, a pulley one, a pulley two, a belt and a rotating rod;

[0005] The output end of the motor is fixedly connected to the pulley one. The central shaft of the pulley one is connected by a bearing and passes through the blanking cylinder. The pulley one is fixedly connected to the rotating rod. The outer side of the rotating rod fits inside the blanking cylinder. A group of evenly arranged grooves are provided on the outer side of the rotating rod. The pulley one and the pulley two are connected by the belt. The central shaft of the pulley two is connected by a bearing and passes through the grinding box. The pulley two is fixedly connected to the grinding roller. A gap is left between the lower side of the grinding roller and the arc-shaped hole plate. Both ends of the arc-shaped hole plate are fixedly connected to one end inside the grinding box. Both ends of the arc-shaped hole plate are respectively fixedly connected to the lower ends of the corresponding inclined plates. The outer sides of the pair of inclined plates fit the inner wall of the grinding box.

[0006] A further setting of the present utility model is that the diameter of the first pulley is larger than that of the second pulley, the belt is a synchronous belt, and the rotational speed of the second pulley > the rotational speed of the first pulley. This differential setting enables the grinding roller to operate at a higher rotational speed, thereby improving the grinding efficiency; while the rotating rod maintains a relatively low rotational speed to ensure stable feeding of the raw materials.

[0007] A further setting of the present utility model is that the arc-shaped orifice plate is a semi-circular arc, and the arc-shaped orifice plate is provided with a group of uniformly arranged through holes.

[0008] A further setting of the present utility model is that the opening size of the connecting pipe matches the upper opening of the groove, and the opening size of the blanking pipe matches the upper opening of the groove.

[0009] A further setting of the present utility model is that this device is installed on the stirring tank, and a pair of support plates are installed between the stirring tank and the grinding box (generally, the feeding port of the stirring tank is mostly arranged on the upper side of the stirring tank).

[0010] A further setting of the present utility model is that both the hopper and the upper part of the grinding box are rectangular, and both the lower parts are trapezoidal outlets (the difference is that the upper end of the hopper is provided with an opening, and the upper end of the grinding box is closed). A certain distance is left between the pair of inclined plates, the arc-shaped orifice plate and the trapezoidal outlet of the grinding box for temporarily storing powdered raw materials.

[0011] The beneficial technical effect of the present utility model is that the present utility model is installed at the solid raw material feeding port of the stirring tank. This device grinds granular and caked powdered raw materials into powdered raw materials through the cooperation of the grinding roller and the arc-shaped orifice plate. The ground powdered raw materials continuously and evenly fall into the stirring tank through the groove of the rotating rod, avoiding the situation of difficult stirring caused by uneven solid-liquid distribution when pouring solid raw materials at one time, and avoiding the situation of blockage caused by simultaneous feeding of a large amount of solid raw materials. This device can both grind and feed evenly, serving multiple purposes, and making the subsequent stirring more uniform and rapid. Description of the Drawings

[0016] The following will Figures 1 - 3 describe the preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0017] The present invention provides a feeding mechanism for solid raw materials in the production of film separating agent. When using this device, install the device at the feeding port of the mixing tank (usually on the upper side of the mixing tank), connect the blanking pipe to the feeding port of the mixing tank, place the motor 13 on the upper side of the mixing tank body, pour the solid raw materials into the hopper 1, start the motor 13, the motor 13 drives the pulley I 11 to rotate, the pulley I 11 drives the pulley II 10 to rotate through the belt 5, the pulley I 11 drives the rotating rod 4 to rotate slowly and moderately in the blanking cylinder 12, the pulley II 10 drives the grinding roller 7 to rotate, the solid raw materials in the hopper 1 fall into the grinding box 2 by their own gravity, and the granular and caked powdery raw materials are ground into powdery raw materials by the rotation of the grinding roller 2 in cooperation with the arc-shaped orifice plate 3. The qualified powdery raw materials fall through the through holes of the arc-shaped orifice plate 3, and the unqualified solid raw materials continue to be ground. The solid raw materials always slide to the grinding roller 2 and the arc-shaped orifice plate 3 under the action of a pair of inclined plates 6. The qualified powdery raw materials slide into the connecting pipe 8 along the inverted trapezoidal bottom of the grinding box 2, and the excess powdery raw materials are temporarily stored at the bottom of the grinding box 2. When a groove 9 is communicated with the connecting pipe 8, the powdery raw materials fall into the uppermost groove 9 under the action of their own gravity. By the rotation of the rotating rod 4, the groove 9 filled with raw materials is communicated with the blanking pipe, and the powdery raw materials in the groove 9 fall into the mixing tank along the blanking pipe under the action of their own gravity. And so on, the continuous rotation of the rotating rod 4 makes the raw materials in a group of grooves 9 continuously and evenly fall into the mixing tank, avoiding the situation of difficult stirring caused by uneven solid-liquid distribution when a large amount of solid raw materials are poured at one time, and avoiding the situation of blockage of the blanking pipe caused by the simultaneous feeding of a large amount of solid raw materials. The liquid raw materials can be poured into the mixing tank in advance, or the solid raw materials and the liquid raw materials can be poured into the mixing tank at the same time for stirring. This device can not only grind but also feed at a uniform speed, serving multiple purposes, making the subsequent stirring more uniform and rapid.
