[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] This utility model embodiment provides a sedimentation centrifuge for separating impurities, such as... Figure 1-3 As shown, the centrifuge includes a body 1 and a drum 11 mounted on the body 1. A bottom shell 2 is located on the outer wall of the body 1 and a top shell 3 is located on the top of the bottom shell 2. One side of the bottom shell 2 is hinged to one side of the top shell 3. A lower locking plate 21 is located on the other side of the bottom shell 2, and an upper locking plate 31 is located on the other side of the top shell 3. The sedimentation centrifuge also includes a locking assembly 4 for fixing or loosening the upper locking plate 31 and the lower locking plate 21. The locking assembly 4 includes a rotating shaft 41, which is rotatably mounted on the body 1 via a bearing 42. Several pressure blocks 43 are evenly spaced along the central axis of the rotating shaft 42. One end of the rotating shaft 41 is hinged to one end of a handle 44. The locking assembly 4 also includes a fixing block 45 mounted on the body 1. The side wall of the fixing block 45 is provided with a fixing mechanism that cooperates with the handle 44. The top shell 3 is installed on top of the bottom shell 2. When the top shell 3 is installed on top of the bottom shell 2, the top shell 3 covers the bottom shell 2. After the top shell covers the bottom shell 2, the rotating shaft 41 is rotated to make the pressure block 43 press against the top of the upper locking plate 31. After the pressure block 43 presses against the top of the upper locking plate 31, the handle 44 is rotated to make the handle 44 engage in the fixing groove 451 of the fixing block 45, thus fixing the top shell 3 on top of the bottom shell 2. When the top shell 3 is opened from the bottom shell 2, the handle 44 is rotated to make the handle 44 disengage from the fixing groove 451 of the fixing block 45. After the handle 44 disengages from the fixing groove 451, the rotating shaft 41 is rotated to make the pressure block 43 disengage from the upper locking plate 31. After the pressure block 43 disengages from the upper locking plate 31, the top shell 3 can be opened from the bottom shell 2. The operation is convenient and the drum 11 can be cleaned easily.

[0018] It should be noted that a flexible block 431 is provided on one side of the pressure block 43. The flexible block 431 is either a silicone block or a rubber block. When the pressure block 43 is pressed onto the upper locking plate 31, the flexible block 431 contacts the upper locking plate 31, which can more firmly press and fix the upper locking plate 31 onto the lower locking block 31.

[0019] In this embodiment, a mounting groove 441 is provided inside the end of the handle 44 away from the bottom shell 2. A pressing rod 442 is movably mounted inside the mounting groove 441. One end of the pressing rod 442 extends out from inside the mounting groove 441, and the other end of the pressing rod 442 is connected to the inner end of the mounting groove 441 through an elastic element 443. The elastic element 443 is a spring. A locking block 444 is provided on the outer wall of the other end of the pressing rod 442. A strip-shaped through hole 445 is provided on the side wall of the handle 44. The end of the locking block 444 away from the pressing rod 442 extends out from inside the mounting groove 441 through the strip-shaped through hole 445. At the same time, a locking groove 452 is provided on the top of the fixing block 45 to cooperate with the locking block 444. The locking groove 452 includes a transition groove section 4521 and a positioning groove section 4522 provided at one end of the transition groove section 4521. Both the transition groove section 4521 and the positioning groove section 4522 are straight grooves. The segments 4522 are perpendicular to each other. The end of the transition groove segment 4521 away from the positioning groove segment 4522 is open, and the end of the positioning groove segment 4522 away from the transition groove segment 4521 is closed. When the handle lever 44 is rotated and inserted into the fixing groove 451 of the positioning block 41, the locking block 444 can slide along the transition groove segment 4521 of the slot 452 into the positioning groove segment 4522 and be fixed. This prevents the handle lever 44 from coming off the fixing groove 451 when the machine is in use. When the handle lever 44 is rotated and removed from the fixing groove 451 on the fixing block 45, the pressing rod 442 is pressed by hand. The pressing rod 442 can drive the locking block 444 to move inside the strip-shaped through hole 445, so that the locking block 444 is removed from the positioning groove segment 4522 of the slot 452 and slides out along the transition groove segment 4521. The operation is convenient and the drum 11 can be cleaned easily.

[0020] Specific principle: When the top shell 3 is installed on top of the bottom shell 2, the top shell 3 covers the bottom shell 2. After the top shell is on the bottom shell 2, the rotating shaft 41 is rotated to make the pressure block 43 press against the top of the upper locking plate 31. After the pressure block 43 presses against the top of the upper locking plate 31, the handle 44 is rotated to make the handle 44 engage with the fixing groove 451 of the fixing block 45. At the same time, the locking block 444 can slide along the transition groove section 4521 into the positioning groove section 4522 for fixation, thus fixing the top shell 3 to the top of the bottom shell 2. When the top shell 3 is opened from the bottom shell 2... When the handle lever 44 is rotated, it disengages from the fixing groove 451 on the fixing block 45. At the same time, the pressing rod 442 is pressed by hand. The pressing rod 442 can drive the locking block 444 to move inside the strip-shaped through hole 445, so that the locking block 444 disengages from the positioning groove section 4522 of the locking groove 452 and slides out along the transition groove section 4521. After the handle lever 44 disengages from the fixing groove 451, the rotating shaft 41 is rotated to disengage the pressure block 43 from the upper locking plate 31. After the pressure block 43 disengages from the upper locking plate 31, the top shell 3 can be opened from the bottom shell 2.
