In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

As shown in FIGS. 1-8 , the present invention provides a waste treatment device for enhanced premixing treatment, comprising a mixing barrel 10 , wherein the top and bottom of the mixing barrel 10 are respectively provided with a feed inlet 11 and a discharge outlet 12 , and further comprising a rotating paddle assembly 20 and a mixing and conveying propeller 30 .

The paddle assembly 20 includes a stirring rod shaft, a short stirring rod group 22, a long stirring rod group 23 and a crushing and pushing claw 24. The stirring rod shaft is rotatably arranged in the mixing barrel 10 along the longitudinal direction. Specifically, the short stirring rod group 22 and the long stirring rod group 23 are fixedly arranged on the stirring rod shaft along the transverse direction. The upper part of the stirring shaft 21 is rotatably connected to the mixing barrel 10 through a bearing, and the bottom of the stirring shaft 21 is rotatably connected to the bearing seat 13 at the bottom of the mixing barrel 10. A first motor 40 is installed on the top of the stirring shaft 21. The first motor 40 is connected to the top of the mixing barrel 10 through a bracket 14. The first motor 40 is used to control the rotation of the stirring shaft 21. The stirring shaft 21 stirs the material to be stirred in the mixing barrel 10 in the longitudinal direction.

The crushing and pushing claws 24 are fixed on the short stirring rod group 22 and the long stirring rod group 23 by bolts. When the first motor 40 controls the stirring shaft 21 to rotate, the crushing and pushing claws 24 on the short stirring rod group 22 and the long stirring rod group 23 fully collide with the material to be stirred in the stirring barrel 10, which is beneficial to further break up, cut and stir the material to be stirred.

Specifically, the crushing and pushing claw 24 has a pushing surface 241 for pushing the stirred object, and two intersecting guide surfaces 242 arranged opposite to the pushing surface 241. The guide surface 242 is used to guide the stirred object, and the intersecting edges of the two guide surfaces 242 form a crushing and pressing blade 243. When the stirring shaft 21 rotates, the crushing and pressing blade 243 first contacts the stirred object to be stirred, and cuts and breaks up the stirred object. Under the guidance of the guide surface 242, the cut stirred object continues to contact with other crushing and pushing claws 24.

The mixing and conveying propeller 30 includes a conveying shaft 31, a mixing and stirring paddle 32 and a conveying spiral blade 33. The conveying shaft 31 is rotatably arranged at the bottom of the mixing barrel 10 in the horizontal direction. Specifically, one end of the conveying shaft 31 is rotatably connected to the bearing seat 13 at the bottom of the mixing barrel 10, and the other end of the conveying shaft 31 is rotatably connected to the side wall of the mixing barrel 10 through a bearing. The other end of the output shaft is connected to a second motor 50, and the second motor 50 is used to control the rotation of the output shaft. The mixing and stirring paddle 32 and the conveying spiral blade 33 are fixedly arranged on the conveying shaft 31, and the discharge port 12 is located below the discharge end of the conveying spiral blade 33. Driven by the second motor 50, the conveying shaft 31 stirs the material to be stirred in the mixing barrel 10 in the horizontal direction, and cooperates with the paddle assembly 20 to stir the material to be stirred in the mixing barrel 10 in the vertical direction, so as to effectively break up, cut and stir the material to be stirred.

In one embodiment, two mixing and conveying propellers 30 are disposed opposite to each other at the bottom of the mixing barrel 10, and the axes of the conveying shafts 31 in the two mixing and conveying propellers 30 are collinear. The two mixing and conveying propellers 30 are used together to better stir the material to be stirred in the mixing barrel 10, and the production cost is also low.

In one embodiment, an anti-blocking spiral blade 34 is also provided on the conveying shaft 31. The spiral direction of the anti-blocking spiral blade 34 is opposite to the spiral direction of the conveying spiral blade 33, and the discharge port 12 is located between the anti-blocking spiral blade 34 and the conveying spiral blade 33. When the two second motors 50 control the conveying spiral blades 33 to rotate inward to feed, the material to be mixed in the mixing barrel 10 cannot be discharged from the discharge port 12, which promotes the continued mixing of the material to be mixed. When the mixing effect reaches the expected effect, the user only needs to control the two second motors 50 to make the conveying spiral blades 33 rotate outward to discharge the material, and the mixed material can be directly discharged from the two discharge ports 12, which is simple to operate and easy to use. At the same time, the anti-blocking spiral blade 34 can also effectively prevent the agitated material from accumulating at the discharge port 12, making the discharge smoother.

In one embodiment, the inner cavity of the mixing barrel 10 is divided into a mixing chamber 60 and a heating chamber 70 by two partitions 15 arranged at the bottom of the mixing barrel 10. The mixing chamber 60 is located above the heating chamber 70, and the mixing chamber 60 is connected to the discharge port 12. The mixing and conveying propeller 30 is located in the mixing chamber 60, and a heating medium flows through the heating chamber 70. The heat medium flowing in the heating chamber 70 performs indirect contact heat exchange with the material to be mixed in the mixing barrel 10. The fluidity of the material to be mixed will be enhanced after being heated, thereby achieving a better stirring effect. The design of the heating chamber 70 enables the waste treatment device to have a preheating function, thereby enhancing the fluidity of the material to be mixed.

In one embodiment, the inner wall of the mixing barrel 10 is provided with an annular crushing blade 71, an auxiliary crushing blade 72, a material pressing paddle 73 and a material loosening paddle 74 located in the heating chamber 70. The annular crushing blade 71 has three intersecting crushing blades, the auxiliary crushing blade 72 has three parallel crushing blades, and the material pressing paddle 73 and the material loosening paddle 74 are both inclined and inclined in opposite directions.

During stirring, the material to be stirred will flow circumferentially in the inner cavity of the stirring barrel 10, and the material to be stirred flowing circumferentially will collide with the annular crushing blade 71 and the auxiliary crushing blade 72, thereby being further broken up and cut. The pressing paddle 73 and the loosening paddle 74 can repeatedly move the material to be stirred in the stirring barrel 10, and cooperate with the annular crushing blade 71 and the auxiliary crushing blade 72 to further break up and cut the material to be stirred, so that the stirring and mixing is more uniform.

In one embodiment, the lengths of the multiple crushing and pushing claws 24 on the short stirring rod group 22 are different, and the lengths of the multiple crushing and pushing claws 24 on the long stirring rod group 23 are different. The different lengths of the crushing and pushing claws 24 can collide with the mixture at multiple positions and directions, thereby better breaking up and cutting the mixture.

In one embodiment, a plurality of mixing paddles 32 are sequentially arranged from the inside to the outside on the conveying shaft 31, and adjacent mixing paddles 32 are arranged staggered. The staggered mixing paddles 32 can contact the object to be stirred at multiple different positions, increasing the probability of contact with the unmixed part of the object to be stirred, thereby further making the object to be stirred more evenly mixed.

In one embodiment, blades are provided at both ends of the mixing paddle 32, and the angle between the blades and the axis of the conveying shaft increases by 5° from inside to outside. On the one hand, it can promote the uniformity of mixing, and on the other hand, it can also adjust the conveying speed of the material to be mixed.
