[0027] The present application provides a production device for refractory castable.

[0028] Example one:

[0029] As Figures 1-2As shown, it includes mixing barrel 1 and cover plate 2, the outer surface of mixing barrel 1 is fixedly installed with third hydraulic cylinder 14, the piston rod end of third hydraulic cylinder 14 is fixedly connected with cover plate 2, so that cover plate 2 can be connected above mixing barrel 1 in a lifting manner, so that the top of mixing barrel 1 can be opened by lifting cover plate 2, facilitating thorough cleaning of the inside thereof, the top of cover plate 2 is provided with feeding port 21 for adding raw materials of refractory castable into the inside of mixing barrel 1, the middle part of cover plate 2 is rotatably connected with rotating shaft 22, the top of cover plate 2 is fixedly installed with motor 23, the output shaft end of motor 23 is fixedly connected with the top end of rotating shaft 22, motor 23 can drive rotating shaft 22 to rotate, the bottom end of rotating shaft 22 is fixedly connected with transmission shaft 24, the outer surface of transmission shaft 24 is fixedly connected with a plurality of first stirring rods 25, the outer surface of transmission shaft 24 is slidably connected with a plurality of transmission sleeves 3, transmission shaft 24 is a polygonal prism, after transmission sleeve 3 is sleeved on the surface of transmission shaft 24, transmission shaft 24 can drive transmission sleeve 3 to rotate synchronously, and transmission sleeve 3 can slide up and down on the surface of transmission shaft 24, the outer surface of each of a plurality of transmission sleeves 3 is fixedly connected with a plurality of second stirring rods 31, from top to bottom, first stirring rods 25 and second stirring rods 31 are arranged alternately, adjacent two transmission sleeves 3 are fixedly connected together through a plurality of bridge plates 32, so that a plurality of transmission sleeves 3 can be lifted synchronously, the outer surface of the uppermost transmission sleeve 3 is fixedly connected with a plurality of push plates 33, the top end of a plurality of push plates 33 is fixedly connected with lifting ring 34, the inside of cover plate 2 is slidably connected with a plurality of supporting rods 4, the top of cover plate 2 is provided with hole slot, supporting rod 4 penetrates through hole slot from above to below of cover plate 2 and can slide up and down, the inner side of each supporting rod 4 is rotatably connected with two roller shafts 41, lifting ring 34 is located between two roller shafts 41, the bottom of lifting ring 34 is supported by lower roller shaft 41, when supporting rod 4 rises, lower roller shaft 41 can lift lifting ring 34, so that transmission sleeve 3 rises, when supporting rod 4 descends, upper roller shaft 41 can press down lifting ring 34, so that transmission sleeve 3 descends, the top end of supporting rod 4 is fixedly connected with lifting plate 42, the bottom of lifting plate 42 is fixedly connected with first hydraulic cylinder 43, the bottom of first hydraulic cylinder 43 is fixedly installed on the top of cover plate 2, first hydraulic cylinder 43 can drive lifting plate 42 to lift and descend, so as to achieve the purpose of lifting supporting rod 4.

[0030] Preferably, as Figure 2As shown, the edges of the top and bottom of the lifting ring 34 are provided with chamfers, and the roller shaft 41 is tapered, and the outer surface of the tapered roller shaft 41 is fitted with the chamfer surface at the edge of the lifting ring 34. Since the positions of the contact surfaces of the roller shaft 41 and the lifting ring 34 are different, the circumferences corresponding to the different contact points of the lifting ring 34 rotating one circle are different. Therefore, after the tapered roller shaft 41 is fitted with the chamfer surface at the edge of the lifting ring 34, the angle corresponding to the different contact points of the lifting ring 34 rotating one circle is equal, thereby avoiding the problem of uneven friction between the surface of the roller shaft 41 and the surface of the lifting ring 34.

[0034] As Figures 1-2As shown, based on Embodiment 1, an inclined first scraper 26 is fixedly connected to the outer surface of the bottom end of the drive shaft 24. During stirring, the motor 23 drives the stirring rod to rotate counterclockwise, and the inclined first scraper 26 rotates counterclockwise, which can convey the refractory castable raw material below upward, thereby making the raw material more uniformly mixed. A discharge pipe 11 is provided at the bottom of the outer surface of the mixing cylinder 1. During discharge, the inclined first scraper 26 rotates clockwise, which can convey the refractory castable above it downward, and use centrifugal force to push it downward.

A third stirring rod 61 is hinged to one side of the first sliding sleeve 6.

A second sliding sleeve 7 is slidably sleeved on the outer surface of the second stirring rod 31. A fourth stirring rod 71 is hinged to one side of the second sliding sleeve 7. The other end of the fourth stirring rod 71 is hinged to the first stirring rod 25 adjacent below the second stirring rod 31. When the support rod 4 is raised and lowered by the first hydraulic cylinder 43, the transmission sleeve 3 follows and rises and falls, thereby causing the second stirring rod 31 to rise or fall. This can drive the third stirring rod 61 and the fourth stirring rod 71 to rotate, changing the angle of the third stirring rod 61 and the fourth stirring rod 71, as well as changing the distance between the first stirring rod 25 and the second stirring rod 31, thereby making the raw materials more uniformly stirred.
