Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-3 , the utility model provides a technical solution:

[0024] A liquid mixture stirring device comprises a bracket 1 and a stirring tank 2 arranged on the bracket 1, the stirring tank 2 is connected with a feed pipe 3 and a discharge pipe 4, the feed pipe 3 and the discharge pipe 4 are respectively communicated with the interior of the stirring tank 2, a stirring assembly is arranged in the stirring tank 2, the stirring assembly comprises a driving mechanism 5 arranged on the stirring tank 2, a rotating shaft 6 located in the stirring tank 2 and a plurality of stirring units arranged on the rotating shaft 6 at intervals, the rotating shaft 6 is rotationally connected to the stirring tank 2, and one end of the rotating shaft 6 is transmission-connected to the driving mechanism 5; any stirring unit comprises a bidirectional driving mechanism 5 and two stirring shafts 7 with a hollow structure, the two stirring shafts 7 are transmission-connected to the two driving ends of the bidirectional driving mechanism 5 respectively; any stirring shaft 7 is provided with a vibration mechanism.

[0025] When the liquid mixture is stirred, the relevant liquid mixture can be injected into the stirring tank 2 through the feed pipe 3, and then discharged from the discharge pipe 4 after being stirred evenly by the stirring mechanism. The driving mechanism 5 is used to control the rotation of the rotating shaft 6, so that the rotating shaft 6 can drive a number of stirring units installed thereon to fully stir the liquid mixture. The stirring unit is designed to have this structure, which is convenient for controlling the two stirring shafts 7 to rotate simultaneously for stirring with the same drive. The stirring shaft 7 is designed to be a hollow structure, which is convenient for installing a vibration mechanism therein. The vibration mechanism can make the stirring shaft 7 vibrate when the stirring shaft 7 is stirring, which can increase the stirring effect on the one hand; on the other hand, it can reduce the amount of liquid mixture attached to the outer wall of the stirring shaft 7, which is convenient for later cleaning.

[0026] In some implementations of the present embodiment, the bidirectional drive mechanism 5 includes a double-headed motor 8 and two turntables 9 arranged in a rotating shaft 6. The two turntables 9 are respectively connected to the two driving ends of the double-headed motor 8. The two stirring shafts 7 are respectively arranged on the two turntables 9. The central axis of any stirring shaft 7 is parallel to the rotating shaft 6 of the double-headed motor 8 and is not colinear.

[0027] The bidirectional driving mechanism 5 adopts a double-headed motor 8, which has two output shafts, and the two output shafts can be in the same direction or in the opposite direction, which is convenient for controlling the rotation state of the stirring shaft 7. The central axis of the stirring shaft 7 is parallel to the rotating shaft 6 of the double-headed motor 8 and is not colinear. When the double-headed motor 8 is working, the stirring shaft 7 can rotate around the rotating shaft 6 of the double-headed motor 8 under the control of its output shaft to achieve the purpose of stirring.

[0028] In some implementations of this embodiment, the vibration mechanism includes several groups of hammers arranged at intervals in the stirring shaft 7, and any hammer includes a pin 10 and a hammer ball 11 passed through the pin 10. The two ends of the pin 10 are respectively connected to the stirring shaft 7, and the hammer ball 11 can slide freely on the pin 10.

Under the action of its own gravity, it will slide back and forth freely on the pin shaft 10, and will hit the stirring shaft 7 under the action of gravitational potential energy, causing the stirring shaft 7 to vibrate, thereby achieving the purpose of increasing the stirring effect and reducing the amount of liquid mixture attached to the outer wall of the stirring shaft 7.

[0030] In some implementations of this embodiment, the driving mechanism 5 is a motor capable of realizing forward and reverse rotation functions.

[0031] In this embodiment, the driving mechanism 5 uses a motor that can realize forward and reverse rotation, which is convenient for controlling the direction of the rotating shaft 6 to increase the stirring state of the stirring shaft 7 and facilitate sufficient stirring of the liquid mixture. Common motors that can realize forward and reverse rotation include AC motors, DC motors, and stepper motors.

[0032] In some implementations of this embodiment, a valve 15 is provided on the discharge pipe 4 .

[0033] In this embodiment, the valve 15 is used to control the opening and closing of the discharge pipe 4. When the liquid mixture in the stirring tank 2 is stirred, the valve 15 is closed. After the stirring is completed, the valve 15 is opened to discharge the liquid mixture in the stirring tank 2 through the discharge pipe 4.

[0036] In this embodiment, the anti-sedimentation device is used to stir the inner bottom of the stirring tank 2 to reduce the amount of sedimentation at the inner bottom of the stirring tank 2 during the stirring of the liquid mixture, which is convenient for subsequent discharge and cleaning.

[0037] In some implementations of this embodiment, the anti-sedimentation device includes a scraper 12 and a connecting rod 13, one end of the connecting rod 13 is connected to the rotating shaft 6, and the other end is connected to the scraper 12, and the scraping side of the scraper 12 is always in contact with the inner bottom of the mixing tank 2.

[0038] In this embodiment, when the rotating shaft 6 rotates, the scraper 12 rotates synchronously around the central axis of the rotating shaft 6 driven by the connecting rod 13 to achieve the purpose of scraping and stirring the inner bottom of the mixing tank 2, thereby reducing the amount of sedimentation of the liquid mixture at the bottom of the mixing tank 2.

[0039] Embodiment 3

[0041] In this embodiment, when stirring, the brush 14 is driven by the stirring shaft 7 to be in contact with the inner wall of the stirring tank 2, which can play a stirring role on the one hand; on the other hand, it can reduce the amount of liquid mixture attached to the inner wall of the stirring tank 2, which is beneficial for later cleaning. When the stirring is completed, the rotating shaft 6 continues to rotate, and the brush 14 is always in contact with the inner wall of the stirring tank 2, and the inner wall of the stirring tank 2 can be cleaned by spraying clean water.
