Abstract
Description
Technical Field
[0001] The invention relates to a continuous stirrer and belongs to the technical field of road construction machinery. Background Art
[0002] The working principle of a continuous agitator is similar to that of a centrifugal pump. When the mixed material enters the agitator, the impeller rotates to push the material. The pushing force is related to the density of the material, while the flow rate is related to the rotation speed and the shape of the impeller. The material is mixed in the agitator and the mixing uniformity is good. The material mixing time in the existing road construction field is fixed and cannot be adjusted for different materials. Different materials require different continuous agitators, which have poor applicability. In addition, the material residence time of the conventional continuous agitator is short and the mixing effect is poor. Summary of the invention

DETAILED DESCRIPTION
[0016] Example 1
[0017] like Figures 1 to 3 As shown, the present invention discloses a continuous agitator, which is suitable for pre-mixing of asphalt mixing plants, plant mixing plants, and recycled materials, and includes an agitator pot body 1 with an upper opening, a motor mounting seat 10 is provided on the end face of the agitator pot body 1, and a discharge door 9 is provided below the agitator pot body 1 away from the motor mounting seat 10. Two motors 3 are provided on the motor mounting seat 10, and the motors 3 are fixed on the agitator pot body 1 through the motor mounting seat 10. The motor 3 can control and adjust the stirring speed according to different working conditions to meet the stirring time required for different working conditions.
[0018] Two stirring shafts 2 are arranged in parallel in the horizontal direction in the stirring pot body 1, and two motors 3 rotate in opposite directions and are respectively connected to the two stirring shafts 2 through couplings 4. The motor 3 is used to drive the two stirring shafts 2 to rotate synchronously and in opposite directions in the stirring pot body 1.
[0019] A stirring arm is arranged on the stirring shaft 2, and the stirring arm includes a feed blade stirring arm 5 and a return blade stirring arm 7. The feed blade stirring arm 5 is provided with a feed blade 6, and the return blade stirring arm 7 is provided with a return blade 8. Under the action of the two stirring shafts 2, the mixture forms a surrounding flow motion in the stirring pot body 1.
[0020] like Figure 1 and Figure 4 As shown, a spray assembly 11 is arranged on the side of the blender pot body 1 , and a nozzle 12 is arranged on the spray assembly 11 .
[0021] The present invention can cause the mixture to form several peripheral flow circulation stirring inside the agitator pot, prolong the stirring time of the mixture in the agitator pot, ensure the uniformity of stirring, and improve the stirring effect. In addition, by adjusting the ratio of the feed blade stirring arm and the return blade stirring arm, the stirring time can be adjusted for different materials, thereby improving its applicability.
[0022] Example 2
[0023] like Figures 1 to 3 As shown, the present invention discloses a continuous agitator, which is suitable for pre-mixing of asphalt mixing plants, plant mixing plants, and recycled materials, and includes an agitator pot body 1 with an upper opening, a motor mounting seat 10 is provided on the end face of the agitator pot body 1, and a discharge door 9 is provided below the agitator pot body 1 away from the motor mounting seat 10. Two motors 3 are provided on the motor mounting seat 10, and the motor 3 is a variable frequency reduction motor. The motor 3 is fixed to the agitator pot body 1 through the motor mounting seat 10. The motor 3 can control and adjust the stirring speed according to different working conditions to meet the stirring time required for different working conditions.
[0024] Two stirring shafts 2 are arranged in parallel in the horizontal direction in the stirring pot body 1, and two motors 3 rotate in opposite directions and are respectively connected to the two stirring shafts 2 through couplings 4. The motor 3 is used to drive the two stirring shafts 2 to rotate synchronously and in opposite directions in the stirring pot body 1. Gears 13 are arranged on the output shafts of the motors 3, and the gears 13 on the two motors 3 are engaged with each other, which can avoid the stirring arm being out of sync due to the angle deviation between the shafts.

The stirring arms on different stirring shafts 2 are staggered along the length direction of the stirring shaft 2, thereby obtaining a relatively large shear overlap area, so that the stirring efficiency is higher and the quality is better. The stirring arm includes a feed blade stirring arm 5 and a return blade stirring arm 7. The feed blade stirring arm 5 is equipped with a feed blade 6, and the return blade stirring arm 7 is equipped with a return blade 8. The feed blade 6 and the return blade 8 are the same in size and shape, and are installed in opposite directions. Under the action of the two stirring shafts 2, the mixture forms a surrounding flow motion in the stirrer pot body 1.
[0026] like Figure 1 and Figure 4 As shown, a spray assembly 11 is provided on the side of the agitator pot body 1, and a nozzle 12 is provided on the spray assembly 11. The nozzles 12 are arranged in two rows and are distributed in an eight-shaped shape. The medium sprayed from the nozzles 12 of the spray assembly 11 is distributed in a fan shape, which is more conducive to the uniform mixing of the mixed material. According to different applicable equipment, the spray assembly 11 sprays different materials. When it is applicable to an asphalt mixing station, the spray assembly 11 sprays asphalt; when it is applicable to a plant mixing station, the spray assembly 11 sprays water; when it is applicable to a pre-mixing equipment for recycled materials, the spray assembly 11 sprays recycled material additives.
[0027] The ratio of the feed blade stirring arm 5 and the return blade stirring arm 7 on the stirring shaft can be adjusted according to the requirements of the stirring time under different working conditions. According to the required retention time of the material in the stirring pot, the present invention adjusts the ratio of the feed blade stirring arm and the return blade stirring arm to 9:2, 8:3 or 7:4. The ratio of the feed blade stirring arm and the return blade stirring arm is adjusted to 7:4, which is suitable for use in asphalt mixing plants with a mixing time of 20S for the mixed material; the ratio of the feed blade stirring arm and the return blade stirring arm is adjusted to 8:3, which is suitable for use in plant mixing plants with a mixing time of 15S for the mixed material; the ratio of the feed blade stirring arm and the return blade stirring arm is adjusted to 9:2, which is suitable for use in pre-mixing equipment for recycled materials with a mixing time of 10S for the mixed material.
