[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] like Figures 1 to 3 As shown, a compatibilizer mixing reactor described in an embodiment of the utility model comprises a reactor body 1; a plurality of supporting feet 2 are fixedly connected to the bottom of the reactor body 1, and the supporting feet 2 are regularly arranged in a circular array at the bottom of the reactor body 1; a discharge port 3 is opened at the bottom position of the reactor body 1; a sealed reactor cover 4 is installed on the top of the reactor body 1; a rotating shaft 5 is rotatably connected inside the sealed reactor cover 4; a plurality of stirring blades 6 are fixedly connected to the side wall of the rotating shaft 5, and the stirring blades 6 are regularly arranged in a circular array on the side wall of the rotating shaft 5; a plurality of connecting rods 7 are provided on the side wall of the rotating shaft 5, and the connecting rods 7 are regularly arranged in a circular array on the side wall of the rotating shaft 5; the connecting rod 7 is arranged at a position corresponding to the bottom end of the rotating shaft 5; the end of the connecting rod 7 is fixedly connected to an axle 8 ; A grinding wheel 9 is rotatably connected to the wheel axle 8; the side wall of the grinding wheel 9 is in contact with the inner side wall of the bottom of the reactor body 1; during operation, when the compatibilizer needs to be stirred and mixed, the raw materials of the compatibilizer can be placed in the internal position of the reactor body 1, and then the sealing kettle cover 4 is set at the top position of the reactor body 1, and then the rotating shaft 5 can be driven by a driving motor to rotate, and then the rotating shaft 5 drives the stirring blade 6 to rotate to stir and mix the compatibilizer raw materials inside the reactor body 1. In the process of stirring and mixing the raw materials, the rotating shaft 5 can drive the wheel axle 8 to rotate along with the rotating shaft 5 through the connecting rod 7, and then it can contact the reactor body 1 through the grinding wheel 9 to grind the raw materials, so that the raw materials of the compatibilizer can be made more finely divided, thereby achieving a better stirring and mixing effect of the compatibilizer.

[0025] like Figure 2 and Figure 4 As shown, a plurality of baffles 10 are fixedly connected to the inner wall of the reactor body 1, and the baffles 10 are regularly arranged in a circular array on the inner wall of the reactor body 1; during operation, when the raw material of the compatibilizer is stirred and mixed by the stirring blades 6, by arranging the baffles 10 on the side wall of the reactor body 1 and using the structural design to block the raw material of the compatibilizer by the baffles 10, the function of effectively avoiding the situation in which the raw material of the compatibilizer inside the reactor body 1 moves together with the stirring blades 6 and the raw material of the compatibilizer cannot be stirred is achieved, so that the stirring and mixing effect of the stirring blades 6 on the raw material of the compatibilizer is better.

[0026] like Figure 4 As shown, a plurality of contact grooves 11 are provided on the side wall of the blocking plate 10; the contact grooves 11 are regularly arranged in a linear array on the side wall of the blocking plate 10; during operation, when the raw material of the compatibilizer is blocked by the blocking plate 10, by providing the contact grooves 11 on the side wall of the blocking plate 10, a larger contact area between the raw material of the compatibilizer and the blocking plate 10 can be achieved, thereby enabling the blocking plate 10 to have a better blocking effect on the raw material of the compatibilizer.

[0027] like Figure 3 and Figure 5 As shown, a plurality of sliding seats 12 are fixedly connected to the side wall of the rotating shaft 5; the connecting rod 7 is slidably connected at the internal position of the sliding seat 12; a plurality of springs are fixedly connected between the side wall of the connecting rod 7 and the side wall of the sliding seat 12; during operation, when the agglomerated compatibilizer raw material is crushed by the grinding wheel 9, when the agglomerates of the compatibilizer raw material are harder, when the grinding wheel 9 rolls over the agglomerates, the connecting rod 7 will retract into the interior of the sliding seat 12, thereby protecting the grinding wheel 9, and effectively avoiding the situation where the agglomerates of the compatibilizer raw material are harder and may cause damage to the connecting rod 7 and the grinding wheel 9.

[0028] like Figure 5 As shown, a positioning block 13 is fixedly connected to the side wall of the wheel axle 8; the grinding wheel 9 is rotatably connected to the positioning block 13; during operation, when the grinding wheel 9 rotates on the wheel axle 8, the rotation of the grinding wheel 9 is restricted by setting the positioning block 13 on the wheel axle 8, so that the grinding wheel 9 is less likely to tilt during the rotation, and the rotation of the grinding wheel 9 can be made more stable.

[0029] like Figure 5As shown, a plurality of balls 14 are arranged between the grinding wheel 9 and the positioning block 13; the side walls of the balls 14 are in contact with the side walls of the grinding wheel 9 and the positioning block 13; during operation, when the grinding wheel 9 rotates on the positioning block 13, by arranging the balls 14 between the grinding wheel 9 and the positioning block 13, the sliding friction between the grinding wheel 9 and the positioning block 13 can be converted into rolling friction, thereby making the friction force between the grinding wheel 9 and the positioning block 13 smaller, and reducing the wear between the grinding wheel 9 and the positioning block 13.

[0030] During operation, when the compatibilizer needs to be stirred and mixed, the raw materials of the compatibilizer can be placed in the internal position of the reactor body 1, and then the sealed reactor cover 4 is set at the top position of the reactor body 1. Thereafter, the rotating shaft 5 can be driven to rotate by a driving motor, and then the stirring blade 6 can be driven to rotate by the rotating shaft 5 to stir and mix the raw materials of the compatibilizer inside the reactor body 1. In the process of stirring and mixing the raw materials, the rotating shaft 5 can drive the wheel shaft 8 to rotate with the rotating shaft 5 through the connecting rod 7, and then the grinding wheel 9 can contact the reactor body 1 to grind the raw materials, so that the raw materials of the compatibilizer can be made finer, thereby achieving a better stirring and mixing effect of the compatibilizer.

[0031] When the raw materials of the compatibilizer are stirred and mixed by the stirring blade 6, a blocking plate 10 is set on the side wall of the reactor body 1. The structural design of the blocking plate 10 blocks the raw materials of the compatibilizer, thereby effectively preventing the raw materials of the compatibilizer inside the reactor body 1 from moving along with the stirring blade 6 and failing to stir the raw materials of the compatibilizer, thereby making the stirring and mixing effect of the stirring blade 6 on the raw materials of the compatibilizer better.

[0032] When the blocking plate 10 is used to block the compatibilizer raw material, by opening a contact groove 11 on the side wall of the blocking plate 10, the contact area between the compatibilizer raw material and the blocking plate 10 can be made larger, so that the blocking plate 10 can have a better blocking effect on the compatibilizer raw material.

[0033] When the agglomerated compatibilizer raw material is crushed by the grinding wheel 9, when the agglomerates of the compatibilizer raw material are hard, when the grinding wheel 9 rolls over the agglomerates, the connecting rod 7 will retract into the interior of the sliding seat 12, thereby protecting the grinding wheel 9 and effectively avoiding the situation where the agglomerates of the compatibilizer raw material are hard and may cause damage to the connecting rod 7 and the grinding wheel 9.

[0034] When the grinding wheel 9 rotates on the axle 8, a positioning block 13 is provided on the axle 8 to limit the rotation of the grinding wheel 9, so that the grinding wheel 9 is less likely to tilt during the rotation, and the rotation of the grinding wheel 9 can be made more stable.

[0035] When the grinding wheel 9 rotates on the positioning block 13, by arranging the ball 14 between the grinding wheel 9 and the positioning block 13, the sliding friction between the grinding wheel 9 and the positioning block 13 can be changed into rolling friction, so that the friction force between the grinding wheel 9 and the positioning block 13 can be smaller, and the wear between the grinding wheel 9 and the positioning block 13 is reduced.
