A mixer and an air suction valve are arranged on the fixed cover. The air suction valve is connected with a pressure detector. A turntable bearing is arranged between the rotating ring cover and the fixed cover and installed through the turntable bearing. A sealing rubber ring is arranged on the inner periphery of the rotating ring cover. A plurality of locking devices are arranged at the connection between the rotating ring cover and the bin body. The locking device includes a locking hook, a locking buckle, a pressing handle and a hydraulic rod. The locking hook is arranged on the side of the rotating ring cover. The pressing handle is arranged on the side of the bin body. The locking buckle is arranged on the pressing handle. The hydraulic rod is arranged on the bin body. A sleeve ring is arranged at the top of the hydraulic rod, and the sleeve ring is sleeved on the pressing handle.

Detailed Embodiments

[0015] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0016] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0017] Such as Figures 1-3As shown in the figure, a sealed sand mixer for sand treatment includes a fixed seat 1, a bin body 2 and a cover plate 3. The cover plate 3 is arranged on the bin body 2. The cover plate 3 includes a fixed cover 4 and a rotating ring cover 5. The fixed cover 4 is installed on the fixed seat 1. A mixer and an air suction valve 6 are arranged on the fixed cover 4. The air suction valve 6 is connected with a pressure detector 7. A turntable bearing 9 is arranged between the rotating ring cover 5 and the fixed cover 4 and is installed through the turntable bearing 9. A sealing rubber ring 8 is arranged on the inner periphery of the rotating ring cover 5. A plurality of locking devices 10 are arranged at the connection between the rotating ring cover 5 and the bin body 2. The locking device 10 includes a locking hook 13, a locking buckle 12, a pressing handle 11 and a hydraulic rod 14. The locking hook 13 is arranged on the side of the rotating ring cover 5. The pressing handle 11 is arranged on the side of the bin body 2. The locking buckle 12 is arranged on the pressing handle 11. The hydraulic rod 14 is arranged on the bin body 2. A collar 15 is arranged at the top of the hydraulic rod 14. The collar 15 is sleeved on the pressing handle 11.

[0018] The air suction valve 6 is connected with a controller and controls the air suction and air intake of the air suction valve 6 through the controller; an adjusting bolt is arranged at the connection between the hydraulic rod 14 and the bin body 2 and is installed through the adjusting bolt; the pressing handle 11 is an arc-shaped structure bent outwards.

[0019] During the use process, the materials to be mixed are put into the bin body 2, the cover plate 3 is installed on the bin body 2, the sealing rubber ring 8 is attached to the opening of the bin body 2 to prevent the liquid materials in the bin body 2 from flowing out. The locking buckle 12 is hooked on the locking hook 13, and the collar 15 at the top of the hydraulic rod 14 is sleeved on the pressing handle 11. The pressing handle 11 is in a bent shape so that the collar 15 is not easy to fall off. The hydraulic rod 14 is connected with a controller and controls the telescopic movement of the hydraulic rod 14 through the controller. The controller is started to control the hydraulic rod 14 to shorten, thereby pressing down the pressing handle 11; the air suction valve 6 is controlled to suck out part of the air in the bin body 2, and the pressure detector 7 detects that the air pressure in the bin body 2 reaches a suitable pressure value, so that the pressure in the bin body 2 is less than the external atmospheric pressure. Affected by the atmospheric pressure, the installation of the bin body 2 and the cover plate 3 is more firm and plays a sealing role.
