[0015] The beneficial effects of the utility model are:
[0016] 1. The vertical activated mixer and the pre-mixer form a two-stage mixing system. The pre-mixer realizes the preliminary mixing of the dry powder and the fine material slurry. Due to the characteristics of the pre-mixer with one end inlet and one end outlet, the ratio of the dry powder and the fine material slurry at the outlet is stable. The preliminarily mixed slurry is then homogenized by the vertical activated mixer to form dry powder flocs, which can achieve a high degree of homogeneity. The vertical activated mixer adopts a vertical structure, which solves the problems of slurry leakage and wear at the transverse bearing. The pre-mixer for mixing dry powder and fine aggregate slurry can be connected through the first or second material port as the feed port, and the mixed slurry after mixing by the pre-mixer is subjected to secondary mixing. The mixing adopts rod blades, which is a flow-through sequential mixing. The rod system whips at high speed to shear the dry powder agglomerates in the mixed slurry, so that the mixed slurry has a higher degree of homogenization. During the mixing process, the first and second material ports can continuously feed or discharge materials to achieve continuous sequential discharge.
[0017] 2. When the pre-mixer is connected to the second material port of the vertical activation mixer, the structure is similar to a "U"-shaped communicating vessel, which realizes overflow type discharging. The material level in the vertical activation mixer is always constant, ensuring the mixing time of the pre-mixer and the vertical activation mixer. The vertical activation mixer uses the gravitational potential energy of the slurry in the pre-mixer to discharge the material; on the other hand, due to the limitation of the slurry flow resistance, it is beneficial to control the liquid level of the pre-mixer and improve the efficiency of the first stage of mixing; the liquid level of the pre-mixer can be stabilized by adjusting the height difference between the two stages of the mixer;
[0018] 3. The slurry detection and adjustment unit can detect and adjust the slurry flow rate, and adjust the slurry concentration through the concentration meter feedback, which is beneficial to the vertical activated mixer to improve the homogenization degree of the mixed slurry;
[0019] 4. The drive shaft is fixed by the bearing in the reducer seat and connected to the reducer and the mixing shaft. The mixer has high stability and can achieve a larger speed and load;
[0020] 5. The drain port at the bottom of the mixing barrel is convenient for discharging the residual slurry;
[0021] 6. The mixing barrel is lined with a removable and replaceable wear-resistant plate to ensure the life of the mixing barrel;
[0022] 7. As the vertical activated mixer has higher stirring efficiency, it is helpful to shorten the stirring intensity and stirring time requirements of the pre-mixer, thereby reducing the volume and power of the pre-mixer and reducing the overall power consumption of preparing the finished homogeneous slurry.

[0031] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0032] Example:
[0033] An activation mixer system includes a pre-mixer and a vertical activation mixer, wherein the pre-mixer is a twin-horizontal shaft forced mixer 40, a slurry detection and adjustment unit 62 for monitoring and adjusting the concentration and flow rate is provided between the twin-horizontal shaft forced mixer 40 and the vertical activation mixer, the vertical activation mixer includes a mixing barrel 10 and a stirring member provided in the mixing barrel 10, a driving mechanism is provided on the top of the mixing barrel 10, the stirring member includes a stirring shaft 21 and a stirring rod provided outside the stirring shaft 21, and the stirring shaft 21 is detachably connected to the driving mechanism; the top of the mixing barrel 10 There are respectively provided with material ports on the side walls of the top and the bottom, and the slurry detection and adjustment part 62 includes a second connecting pipe 61, a flow meter, a concentration meter, a flow regulating valve and a second connecting pipe 63 which are connected in series in sequence, wherein the flow meter, the concentration meter and the flow regulating valve are optional, that is, the first connecting pipe 61 and the second connecting pipe 62 are directly connected, the material port located at the top of the mixing barrel 10 is the first material port 11, and the other material port is the second material port 12, the end of the second connecting pipe 63 is connected to the second material port 12, and the end of the second connecting pipe 61 is connected to the twin-horizontal-shaft forced mixer 40.
[0034] The vertical activated mixer includes a mixing barrel 10 and a stirring member arranged in the mixing barrel 10, the stirring member includes a stirring shaft 21 and a stirring rod arranged outside the stirring shaft 21, the top of the mixing barrel 10 is open, and a detachable barrel cover 14 is provided at the opening, and a driving mechanism is installed on the barrel cover 14, the driving mechanism includes a motor 31, a reducer 32, a reducer 32 seat and a driving shaft 34, the reducer 32 seat is provided on the barrel cover 14, the reducer 32 is connected to the motor and is arranged on the reducer 32 seat, the top end of the driving shaft 34 is connected to the reducer 32 through the reducer 32 seat, and the bottom end of the driving shaft 34 and the top end of the stirring rod are connected by a flange; a first material port 11 is provided on the side wall of the top of the mixing barrel 10, and a second material port 12 is provided on the side wall of the bottom.

When the stirring shaft 21 is connected to the stirring vertical rods 23, connecting rods can be vertically extended from the top and bottom to connect the top and bottom of the stirring vertical rods 23 respectively.
[0036] The working principle of the above technical solution is as follows:
[0037] The vertical activated mixer and the twin-horizontal shaft forced mixer 40 form a two-stage mixing. The twin-horizontal shaft forced mixer 40 realizes the preliminary mixing of the dry powder and the fine material slurry. Due to the characteristics of the twin-horizontal shaft forced mixer 40 that it enters at one end and exits at the other end, the ratio of the dry powder and the fine material slurry at the discharge port is stable. The preliminary mixed slurry is then homogenized by the vertical activated mixer to form dry powder flocs, which can achieve a high degree of homogeneity. The structure composed of the vertical activated mixer and the twin-horizontal shaft forced mixer 40 is similar to a "U"-shaped communicating vessel, which realizes overflow type discharging. The material level in the vertical activated mixer is always constant, ensuring the mixing time of the vertical activated mixer. The vertical activated mixer uses the gravitational potential energy of the slurry in the twin-horizontal shaft forced mixer 40 to discharge the material. On the other hand, due to the limitation of the slurry flow resistance, it is beneficial to control the liquid level of the twin-horizontal shaft forced mixer 40 and improve the efficiency of the first stage of mixing. The liquid level of the twin-horizontal shaft forced mixer 40 can be stabilized by adjusting the height difference between the two-stage mixers.
[0038] The twin-horizontal shaft forced mixer 40 can discharge the mixed slurry after stirring into the mixing barrel 10. The motor drives the driving shaft 34 to rotate through the reducer, so that the stirring shaft 21 in the mixing barrel 10 rotates, and drives the stirring rod to whip the dry powder in the mixed slurry at high speed, so that the mixed slurry is more homogenized. The feeding and discharging are continuous during the stirring process to achieve continuous sequential discharge.
[0039] In another embodiment, if Figure 1-6 As shown, a drain port 13 is provided at the bottom of the mixing barrel 10. It is convenient to open and discharge the residual slurry while cleaning and stirring.
[0040] In another embodiment, a removable wear plate is provided on the inner wall of the mixing barrel 10. The wear plate replaces the inner wall of the mixing barrel 10 to rub against the slurry during mixing, and can be replaced after long-term use to ensure the life of the mixing barrel 10.
[0041] In another embodiment, if Figure 4 As shown, based on the above embodiment, the difference is that the first material port 11 of the mixing barrel 10 is connected to the twin-horizontal shaft forced mixer 40 through the slurry detection and adjustment part 62.
[0042] In another embodiment, if Figure 5 As shown, based on the above embodiment, the difference is that the pre-mixer is a vertical mixer 50 , and the second material port 12 of the mixing barrel 10 is connected to the vertical mixer 50 through a slurry detection and adjustment part 62 .
[0043] In another embodiment, if Figure 6 As shown, based on the above embodiment, the difference is that the pre-mixer is a vertical mixer 50 , and the first material port 11 of the mixing barrel 10 is connected to the vertical mixer 50 through a slurry detection and adjustment part 62 .
