DETAILED DESCRIPTION

[0015] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, a drying mixer for injection production includes a mixing tank 1. The outside of the mixing tank 1 is integrated with a jacket 2, and the upper and lower sides of one side of the jacket 2 are respectively integrated with a water inlet 22 and a water outlet 21. A discharge valve 3 is installed at the outlet opened at the lower part of the mixing tank 1, and a feed valve 4 is installed at the feed inlet opened on one side of the upper part of the mixing tank 1. The mixing tank 1 is also equipped with a driving component 5 and a stirring component 6.

[0016] In this embodiment, combined with the Figure 2As shown, the driving assembly 5 includes a mounting frame 51, which is fixedly mounted on the upper part of the mixing tank 1, and a gear box 52 is fixedly mounted on the upper part of the mounting frame 51, and a stirring motor 53 is fixedly mounted on the gear box 52, and the output shaft of the stirring motor 53 is keyed to the input end of the gear box 52, and the stirring assembly 6 includes a rotating shaft 61, and the rotating shaft 61 is alternately provided with a first stirring blade 62 and a second stirring blade 63 from top to bottom, the first stirring blade 62 is fixedly mounted on the rotating shaft 61, and the second stirring blade 63 is rotatably connected to the rotating shaft 61, and a longitudinal connecting rod 64 is fixedly mounted between the two ends of the second stirring blades 63, and a collar 66 is sleeved on the outer part of the upper end of the rotating shaft 61, and the collar 66 is connected to the rotating shaft 61 through The fixing bolts 67 are connected, and an oblique connecting rod 65 is fixedly installed between the collar 66 and the two ends of the second stirring blade 63 set on the upper side. The output shaft of the gear box 52 is connected to the upper end coupling of the rotating shaft 61. Before feeding, the user opens the fixing bolts 67, rotates the collar 66, rotates the second stirring blade 63 to a position close to the first stirring blade 62, and moves the first stirring blade 62 away from the position of the feed valve 4. When feeding, avoid the material from impacting the first stirring blade 62 and the second stirring blade 63 to cause deformation. After feeding is completed, rotate the collar 66 again to open the second stirring blade 63, tighten the fixing bolts 67, and the stirring motor 53 drives the rotating shaft 61 to rotate through the gear box 52 to play a stirring role.

[0017] In this embodiment, specifically, the upper end of the rotating shaft 61 passes through a through hole opened in the middle of the upper side of the mixing tank 1 .

[0018] In this embodiment, specifically, an annular protrusion is integrated into the middle part of the bottom of the mixing tank 1, and the lower end of the rotating shaft 61 is arranged inside the annular protrusion. The rotating shaft 61 can rotate relative to the annular protrusion. The annular protrusion serves as a limit for the rotating shaft 61 to ensure the stability of the rotation of the rotating shaft 61.

[0019] How it works

[0020] In the present invention, the material to be dried is transported into the mixing tank 1 through the feed valve 4, the external circulating heating liquid is input into the jacket 2 from the water inlet 22, and discharged from the jacket 2 from the water outlet 21, thereby heating and drying the mixing tank 1 and the material in the mixing tank 1, and the stirring component 6 stirs the material so that the material is heated more evenly.
