[0020] As Figures 1-3 shown, a storage tank for engineering plastics includes a tank body 1. A feed inlet 2 is opened at the upper part of the tank body 1, and a discharge outlet 3 is opened at the bottom of the tank body 1. The bottom of the tank body 1 is in a converging setting. It also includes an upper cover 4, a discharge cylinder body 5, a buffer limiting component 6 and a pushing mechanism 7. The upper cover 4 is hinged to the upper end of the tank body 1 for sealing and covering the feed inlet 2. The discharge cylinder body 5 is fixedly connected to the bottom of the tank body 1 and is communicated with the discharge outlet 3. The buffer limiting component 6 is fixedly connected to the inner side wall of the tank body 1, and the buffer limiting components 6 are arranged at equal intervals along the axial direction of the tank body 1. The pushing mechanism 7 is rotatably arranged at the center inside the tank body 1 for pushing the engineering plastic particles to flow inside the tank body 1. The inside of the upper cover 4 is in a cavity setting, and a ventilation component 8 is arranged inside the upper cover 4. Open the upper cover 4, fill the tank body 1 with engineering plastics through the feed inlet 2, and store them in the tank body 1. The pushing mechanism 7 can be rotated in the reverse direction to push the dropped engineering plastics upward, so that they fall to the inner edge of the tank body 1 and are located between the buffer limiting components 6 to fill the tank body 1. A ventilation mechanism is arranged inside the upper cover 4 to increase the ventilation inside the tank body 1.
[0021] As Figure 2 and Figure 3 shown, in order to slow down the pressure at the bottom of the tank body 1 during storage and buffer the falling of the engineering plastics inside the tank body 1 during discharging, the buffer limiting component 6 includes a limiting plate 9 and a limiting ring 10. One end of the limiting plate 9 is fixedly connected to the inner side wall of the tank body 1, and the limiting plates 9 are symmetrically distributed. The limiting ring 10 is fixedly connected between the symmetric limiting plates 9. The limiting ring 10 is in a converging setting at the bottom. The limiting ring 10 is connected to the inside of the tank body 1 through the two side limiting plates 9. When the engineering plastics are stored, they are distributed between the buffer limiting components 6. When discharging, the engineering plastics fall, pass through the limiting ring 10 and contact the limiting plate 9 to slow down the falling speed of the engineering plastics and achieve the effect of buffering the falling of the engineering plastics.
[0022] As Figure 2As shown in the figure, in order to make the engineering plastics evenly distributed in the tank body 1 during material storage and at the same time achieve uniform discharging at the discharging port 3 at the bottom of the tank body 1, the pushing mechanism 7 includes an upper baffle 15, a lower baffle 16, a rotating shaft 17, a spiral blade 18 and a rotating motor 19. The upper baffle 15 is fixedly connected to the inner side wall of the tank body 1 near one end of the feeding port 2, the lower baffle 16 is fixedly connected to the inner side wall of the tank body 1 near one end of the discharging port 3, the rotating motor 19 is installed on the bottom wall of the discharging cylinder body 5, one end of the rotating shaft 17 is rotatably arranged on the bottom wall of the upper baffle 15, the other end of the rotating shaft 17 penetrates through the lower baffle 16 and extends to the bottom wall of the discharging cylinder body 5 and is connected to the output end of the rotating motor 19. The spiral blade 18 is wound around the outer side wall of the rotating shaft 17 and is located inside a plurality of limiting rings 10 arranged at uniform intervals. A material dropping port 11 is formed in the outer side wall of the discharging cylinder body 5, a protective door 12 is hinged in the material dropping port 11, and the inner bottom wall of the discharging cylinder body 5 is arranged in a conical shape;
[0023] When storing materials in the tank body 1, the rotating motor 19 is driven to rotate in the reverse direction, so that the spiral blade 18 rotates in the reverse direction in the limiting ring 10, pushing the engineering plastics to move upward. The dropped engineering plastics come into contact with the spiral blade 18 and are dispersed to the outside of the limiting ring 10, evenly dispersed inside the tank body 1 and located between each layer of buffer limiting components 6;
[0024] When discharging materials, the rotating motor 19 is driven to rotate forward, driving the rotating shaft 17 and the spiral blade 18 to rotate forward. The spiral blade 18 pushes the engineering plastics to move downward in the multi-layer limiting rings 10. At the same time, the bottom of the spiral blade 18 pushes the engineering plastics at the discharging port 3 to move, so that the engineering plastics fall slowly and enter the discharging cylinder body 5, avoiding blockage of the discharging port 3. At the same time, the protective door 12 is opened, the engineering plastics come into contact with the inner bottom wall of the discharging cylinder body 5, and are evenly discharged from the two side material dropping ports 11.
[0025] As Figures 2-5As shown in the figure, in order to keep the inside of the tank body 1 dry and promote the air flow inside the tank body 1, a through hole 13 is opened in the upper part of the outer side wall of the discharge cylinder body 5, and a rubber valve flap 14 is arranged in the through hole 13. The ventilation assembly 8 includes an air pump 20. The air outlet end of the air pump 20 is communicated with the inside of the upper cover 4. A ventilation hole 21 is opened on the inner bottom wall of the upper cover 4. The ventilation holes 21 are arranged at uniform intervals. An electric heating wire 22 is arranged inside the upper cover 4. Two side parts of the upper part of the upper cover 4 are fixedly connected with vertical plates 23. The vertical plates 23 are symmetrically distributed. The upper parts of the symmetric vertical plates 23 are fixedly connected with a protection plate 24. The protection plate 24 is used to shield the air pump 20 to prevent the air pump 20 from getting water. The air pump 20 is driven to extract gas and pump the gas into the inside of the upper cover 4. The electric heating wire 22 is powered on. After the air contacts the electric heating wire 22, it becomes dry and enters the inside of the tank body 1 through the ventilation hole 21. Under the pressure of the air pump 20, the gas moves from top to bottom and enters the discharge cylinder body 5, and is discharged by squeezing the rubber valve flap 14 at the through hole 13 on the side wall of the discharge cylinder body 5. The rubber valve flap 14 prevents the air at the bottom from pouring in and has a certain pressure to block the through hole 13.
[0026] Among them, a support ring 25 is fixedly connected to the lower part of the outer side wall of the tank body 1. A support leg 26 is arranged at the bottom of the support ring 25. The support legs 26 are symmetrically distributed in pairs. The support ring 25 is used to connect the tank body 1 and the support legs 26, and the height of the tank body 1 is increased through the support legs 26.
[0027] During specific use, the operator opens the upper cover 4, fills the engineering plastics into the inside of the tank body 1 through the feed port 2, and stores them in the tank body 1. The rotary motor 19 is driven to rotate reversely, so that the spiral blade 18 rotates reversely in the limit ring 10, pushes the engineering plastics to move upward. The dropped engineering plastics contact the spiral blade 18 and disperse to the outside of the limit ring 10, are evenly dispersed inside the tank body 1, and are located between the buffer limit assemblies 6 of each layer, and the tank body 1 is filled.
[0028] During storage, the air pump 20 is driven to extract gas and pump the gas into the inside of the upper cover 4. The electric heating wire 22 is powered on. After the air contacts the electric heating wire 22, it becomes dry and enters the inside of the tank body 1 through the ventilation hole 21. Under the pressure of the air pump 20, the gas moves from top to bottom and enters the discharge cylinder body 5, and is discharged by squeezing the rubber valve flap 14 at the through hole 13 on the side wall of the discharge cylinder body 5.
[0029] During discharging, the rotary motor 19 is driven to rotate forward, and drives the rotating shaft 17 and the spiral blade 18 to rotate forward. The spiral blade 18 pushes the engineering plastics to move downward in the multi-layer limit ring 10. At the same time, the bottom of the spiral blade 18 pushes the engineering plastics at the discharge port 3 to move, so that the engineering plastics slowly fall, enter the discharge cylinder body 5, and prevent the discharge port 3 from being blocked. At the same time, the protection door 12 is opened, and the engineering plastics contact the inner bottom wall of the discharge cylinder body 5 and uniformly fall from the two side discharge ports 11.
