[0029] See also Figure 1-Figure 4As shown, the utility model provides a sludge solidifying agent mixing device, including a shell 1, a plurality of stirring rods 7, an auger rod 8 and a driving assembly. A feeding barrel 2 is provided on the top of the shell 1, a receiving barrel 3 is rotatably provided inside the shell 1, a discharge pipe 4 is provided at the bottom of the shell 1, and a valve is provided on the discharge pipe 4 for opening and closing the discharge pipe 4; a receiving port 31 is provided above the receiving barrel 3, and a plurality of discharge holes 32 are also provided on the side wall of the receiving barrel 3, a feeding port is provided below the feeding barrel 2, and the receiving port 31 is connected to the feeding port, and a curing agent feeding pipe 5 and a sludge feeding pipe 6 are connected to the upper side wall of the feeding barrel 2 respectively; a plurality of stirring rods 7 are arranged at intervals on the outer side wall of the receiving barrel 3; the auger rod 8 is rotatably provided in the feeding barrel 2; and the driving assembly is used to drive the receiving barrel 3 and the auger rod 8 to rotate.

[0030] By adding curing agent and sludge into the curing agent feeding pipe 5 and the sludge feeding pipe 6 respectively and entering into the feeding barrel 2, the curing agent and sludge in the feeding barrel 2 are initially stirred and mixed for the first time under the rotation of the auger rod 8. The curing agent and sludge after the first mixing enter the receiving barrel 3 from the feeding port under the action of gravity. Due to the centrifugal force generated by the rotation of the receiving barrel 3, they are mixed for the second time under the action of centrifugal force after entering the receiving barrel 3, and are thrown out from the discharge hole 32 into the shell 1 under the action of centrifugal force. At this time, the stirring rod 7 also rotates with the rotation of the receiving barrel 3, so that the stirring rod 7 stirs and mixes the curing agent and sludge in the shell 1 for the third time. The three mixing actions of the curing agent can quickly and fully mix the curing agent and sludge evenly, and the mixed curing agent and sludge will be discharged through the discharge pipe.

[0031] Furthermore, it also includes a material picking structure, which includes a material picking tube 11 and a material picking rod 12. The material picking tube 11 is inserted into the upper end of the shell 1 and extends into the shell 1; the material picking rod 12 is inserted into the material picking tube 11, and the lower end of the material picking rod 12 is located outside the material picking tube 11, and a plurality of material clamping grooves 121 are opened on the side wall of the material picking rod 12.

[0032] When in use, the material picking rod 12 is inserted into the shell body 1 through the material picking tube 11, so that the material groove 121 on the material picking rod 12 penetrates into the curing agent and sludge, and then the material picking rod 12 is pulled out from the material picking tube 11, wherein the curing agent and sludge will be stuck in the material groove 121. By observing or detecting the state of the curing agent and sludge in the material groove 121, it can be determined whether the curing agent and sludge inside the shell body 1 are successfully mixed.

[0033] Furthermore, the stirring rod 7 is extended transversely, and a fixing rope 71 or a fixing rod is connected between two adjacent stirring rods 7 in the upper and lower directions.

[0034] The laterally extending stirring rod 7 stirs and mixes the curing agent and sludge in the shell 1 laterally when rotating with the receiving barrel 3. By setting a fixed rope 71 or a fixed rod, the longitudinal mixing of the sludge and the curing agent can be increased, thereby improving the mixing efficiency of the sludge and the curing agent and avoiding stratification of the mixed sludge and the curing agent due to uneven mixing.

[0035] Specifically, a material guide plate 13 is fixedly connected to the lower end of the side wall of the material receiving barrel 3 , and the lower end of the material guide plate 13 is in contact with the inner bottom wall of the shell 1 .

[0036] By arranging a material guide plate 13 at the lower end of the side wall of the material receiving barrel 3, and the lower end of the material guide plate 13 is in contact with the bottom wall of the shell 1, on the one hand, when the material receiving barrel 3 rotates, the material guide plate 13 rotates accordingly to stir the sludge and curing agent in the shell 1, and on the other hand, the mixed sludge and curing agent move toward the discharge pipe under the push of the material guide plate 13, thereby facilitating the discharge of the mixture.

[0037] Furthermore, a material gathering cover 14 is coaxially provided at the upper end of the receiving barrel 3, and the upper end of the material gathering cover 14 is covered at the lower end of the feeding barrel 2. Preferably, the material gathering cover 14 is integrally formed with the feeding barrel 2, and the diameter of the barrel mouth at the upper end of the feeding barrel 2 can be set to be larger than the diameter of the lower end of the feeding barrel 2 and the feeding barrel 2. Preferably, the diameter of the material gathering cover 14 is twice the diameter of the feeding barrel 2, so that the sludge and curing agent inside the feeding barrel 2 can fall smoothly into the receiving barrel 3.

[0038] Specifically, a guide surface 101 is provided at the lower end of the inner wall of the shell 1, and the guide surface 101 gradually approaches the center from top to bottom. Preferably, the guide surface 101 is set as an arc-shaped guide surface 101. The guide surface 101 can be achieved by setting a guide plate between the inner wall of the shell 1 and the lower bottom wall, or the inner lower end of the shell 1 can be set as an arc structure.

[0039] The guide surface 101 is provided to facilitate guiding the mixture of sludge and curing agent, and also to increase the angle between the side wall and the bottom wall of the shell 1, thereby preventing the mixture of sludge and curing agent from being stuck in a dead corner in the shell 1 and being difficult to clean or not being removed cleanly.

[0040] Furthermore, a crushing structure 15 is provided at the entrance of the sludge feeding pipe 6, and the crushing structure 15 includes a crushing box 151, two crushing rollers 152, a main gear 153 and a sub-gear 154, and a driving motor 155. The upper end of the crushing box 151 is open, and the lower end is connected to the sludge feeding pipe 6; the two crushing rollers 152 are arranged in the crushing box 151 to rotate towards each other, and a plurality of spaced extrusion plates 156 are convexly provided on the two crushing rollers 152, and the extrusion plates 156 on the two crushing rollers are staggered in sequence; the main gear 153 and the sub-gear 154 are respectively connected to one end of the two crushing rollers 152, and the main gear 153 is meshed with the sub-gear 154; the driving motor 155 is connected to the main gear 153 to drive the main gear 153 to rotate.

[0041] The main gear 153 is driven to rotate by the driving motor 155, so that the two crushing rollers 152 are driven to rotate towards each other under the meshing action of the main gear 153 and the sub-gear 154, thereby driving the extrusion plate 156 to extrude and crush the incoming sludge, thereby preventing the sludge particles from being too large or the presence of large debris in the sludge from being unable to mix with the curing agent.

[0042] Specifically, the driving assembly includes a first motor 9 and a second motor 10, which are respectively mounted on the upper end of the feeding cylinder 2 and the lower end of the housing 1, and are respectively used to drive the auger rod 8 and the receiving cylinder 3 to rotate.

[0043] The auger rod 8 and the material receiving barrel 3 are driven to rotate by a motor, and the speed is fast and easy to control.
