It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In order to solve the technical problem that it is difficult to clean the inner wall of the conveying cylinder and the powder on the spiral, the utility model provides an easy-to-clean plastic particle homogenizing tank device, which can conveniently clean the inner wall of the conveying cylinder and the powder on the spiral.

[0027] It should be noted that the easy-to-clean plastic particle homogenizing tank device described in the present invention is used for but not limited to a homogenizing tank device, etc. For the sake of convenience, in the present invention, only the easy-to-clean plastic particle homogenizing tank device is used in a homogenizing tank device as an example for explanation. The principle of the easy-to-clean plastic particle homogenizing tank device being used in other types of equipment is essentially the same as the principle of being used in a homogenizing tank device, and will not be described one by one here.

[0028] See also Figure 1 , Figure 1 This is a structural diagram of an easy-to-clean plastic particle homogenizing tank device in one embodiment of the present invention. The easy-to-clean plastic particle homogenizing tank device includes a tank body 1 and a lifting mechanism 2.

[0029] The tank body 1 has a receiving cavity 11. The lower end of the tank body 1 is provided with a through hole communicating with the receiving cavity, a discharge port 12 and a blanking port 13. The discharge port 12 is provided with a discharge valve 14, and the blanking port 13 is provided with a blanking valve 15.

[0030] See also Figure 1-Figure 5 The lifting mechanism 2 includes a conveying cylinder 21, a feed hopper 22, a screw 23 and a rotating drive member 24. The upper end of the conveying cylinder 21 vertically passes through the through hole and reaches the upper part of the inner cavity of the tank body 1. A plurality of openings 211 are provided on the side wall of the conveying cylinder 21. Each of the openings 211 is hinged with a cover plate 212. A feed hole is provided at the lower end of the conveying cylinder 21. The outlet of the feed hopper 22 is connected to the feed hole, and the inlet of the feed hopper 22 is connected to the drop port 13. The upper end of the conveying cylinder 21 is opened, and the screw 23 is rotatably set in the conveying cylinder 21. The rotating drive member 24 is connected to the screw 23 and is used to drive the screw 23 to rotate.

[0031] During use, the plastic particles are poured into the feed hopper 22, and the plastic particles enter the lower end of the conveying cylinder 21 from the feed hopper 22. The rotating drive member 24 is turned on, and the rotating drive member 24 drives the screw 23 to rotate, so that the plastic particles at the lower end of the conveying cylinder 21 move upward and are finally discharged from the upper end opening of the conveying cylinder 21, and then fall to the inner bottom of the tank body 1 under the action of gravity. At this time, the blanking valve 15 is opened and the discharge valve 14 is closed. Therefore, the plastic particles will fall into the feed hopper 22 through the blanking port 13, and then enter the lower end of the conveying cylinder 21, and then be transported upward and fall again. This cycle is repeated continuously to achieve homogenization of the material particles. When the homogenization is completed, the blanking valve 15 is closed, and the discharge valve 14 is opened, and the homogenized material is discharged from the discharge port 12.

[0032] When it is necessary to clean the powder on the inner wall of the conveying cylinder 21 and the spiral 23, each cover plate 212 is opened, and the nozzle is passed through the opening 211 into the conveying cylinder 21 to flush the inner wall of the conveying cylinder 21 and the spiral 23, which can improve the flushing effect. After flushing is completed, each cover plate 212 can be closed. The utility model changes the side wall of the conveying cylinder 21 from a closed type to an openable type, thereby facilitating the flushing of the inner wall of the conveying cylinder 21 and the spiral 23, thereby improving the flushing effect.

[0033] In one embodiment, see Figure 2-Figure 5 The opening 211 of the conveying cylinder 21 is hinged to the corresponding cover plate 212 via a plurality of hinges 213. The cover plate 212 is arc-shaped. When the cover plate 212 is buckled with the corresponding opening 211, the opening 211 is in a closed state.

[0034] In one embodiment, see Figure 2-Figure 5A lock body 214 is provided on the outer edge of each opening 211 , and a lock block 2121 is provided on each cover plate 212 to match the corresponding lock body 214 .

[0035] In one embodiment, see Figure 2-Figure 5 The lock body 214 includes a nut 2141 and a screw 2142. The nut 2141 is fixed to the outer edge of the opening 211. The screw 2142 is threadedly inserted into the nut 2141. The locking block 2121 is fixed to the cover 212. A locking hole is provided on the locking block 2121. One end of the screw 2142 is used to be inserted into the locking hole. When in use, Figure 2 and Figure 3 As shown, when it is necessary to close each opening 211, the cover plate 212 is closed on the opening 211, and then the screw 2142 is rotated so that one end of the screw 2142 is inserted into the lock hole on the locking block 2121, thereby locking the cover plate 212; Figure 4 and Figure 5 As shown, when each opening 211 needs to be opened, the screw rod 2142 is first rotated in the opposite direction to make one end of the screw rod 2142 leave the lock hole on the lock block 2121, and then the cover plate 212 is rotated to the open position.

[0036] In one embodiment, see Figure 1 The easy-to-clean plastic particle homogenizing tank device also includes a bracket 3, and the lower ends of the tank body 1 and the conveying cylinder 21 are fixed to the bracket 3.

[0037] In one embodiment, see Figure 1 The upper end of the conveying cylinder 21 is connected to the inner wall of the tank body 1 via a plurality of connecting rods 25, thereby improving the stability of the conveying cylinder 21.

[0038] In one embodiment, see Figure 1 The rotating drive member 24 includes a rotating shaft 241 and a rotating drive motor 242. The rotating shaft 241 is rotatably arranged in the conveying cylinder 21. The screw 23 is fixed to the rotating shaft 241. The rotating drive motor 242 is connected to the rotating shaft 241 and is used to drive the rotating shaft 241 to rotate, thereby driving the screw 23 to rotate.

[0039] In one embodiment, see Figure 1 A mounting hole is provided at the upper end of the conveying cylinder 21 , and the upper end of the rotating shaft 241 passes through the mounting hole. The shell of the rotating drive motor 242 is fixed to the conveying cylinder 21 , and the output shaft of the rotating drive motor 242 is fixedly connected to the rotating shaft 241 .

[0040] In one embodiment, see Figure 1A manhole 16 is provided at the upper end of the tank body 1, and a protective cover 17 is detachably mounted on the manhole 16. When cleaning or maintenance is required, the protective cover 17 can be opened, and the staff can then enter the tank body 1 through the manhole 16 to perform operations.

[0041] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: when in use, plastic particles are poured into the feed hopper 22, and the plastic particles enter the lower end of the conveying cylinder 21 from the feed hopper 22, and the rotating drive member 24 is turned on. The rotating drive member 24 drives the screw 23 to rotate, so that the plastic particles at the lower end of the conveying cylinder 21 move upward and are finally discharged from the upper end opening of the conveying cylinder 21, and then fall to the inner bottom of the tank body 1 under the action of gravity. At this time, the blanking valve 15 is opened and the discharge valve 14 is closed. Therefore, the plastic particles will fall into the feed hopper 22 through the blanking port 13, and then enter the lower end of the conveying cylinder 21, and then be transported upward and fall again. This cycle is repeated continuously to achieve homogenization of the material particles. When the homogenization is completed, the blanking valve 15 is closed, and the discharge valve 14 is opened, and the homogenized material is discharged from the discharge port 12.

[0042] When it is necessary to clean the powder on the inner wall of the conveying cylinder 21 and the spiral 23, each cover plate 212 is opened, and the nozzle is passed through the opening 211 into the conveying cylinder 21 to flush the inner wall of the conveying cylinder 21 and the spiral 23, which can improve the flushing effect. After flushing is completed, each cover plate 212 can be closed. The utility model changes the side wall of the conveying cylinder 21 from a closed type to an openable type, thereby facilitating the flushing of the inner wall of the conveying cylinder 21 and the spiral 23, thereby improving the flushing effect.

[0043] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
