Abstract

The utility model discloses a wet pelleting machine which comprises a pelleting shaft, wherein the pelleting shaft is composed of a pipe, end shafts assembled at both ends of the pipe, a screw blade fixed to the pipe, a plurality of tooth stirring rods fixed to the pipe, stirring teeth arranged on each stirring rod and stiffening ribs arranged on each stirring tooth; both of the two ends of the pipe and the end shafts are respectively provided with more than two mutually suited ladders, and the two end shafts are fixedly connected with the pipe through more than two positioning rings arranged on the ladders thereof. As the further improvement of the utility model, the tooth stirring rods are a plurality of tooth stirring rods which are uniformly distributed and fixed to the surface of the pipe, at least four groups of tooth stirring rods are spirally arranged, the stirring teeth are connected with the tooth stirring rods in a screwed connection mode and the stiffening ribs are fixed to a position which is 20 to 50 mm away from the top of the stirring teeth. The utility model has the advantages that under the condition of guaranteeing the intensity of the pelleting shaft thereof, the manufacture process is simplified, the manufacture cost is reduced and the pelleting effect is improved.

Description

A kind of wet granulator

Technical field

The utility model relates to a kind of production particulate matter, especially carbon powder dust is made granular sooty wet granulator.

Background technology

At present, the key part of known wet granulator-granulation axle is by two butt axles, pipe, screw-blade, stir ratch, stir tooth and stiffening web is assembled, be fixed with the end axle at pipe two ends assembly welding, on pipe, be welded with screw-blade and stir gear mechanism by three spirals that stir ratch, stir tooth, stiffening web is formed, stirring tooth is welded on and stirs on the ratch, stiffening web is weldingly fixed on the top of stirring tooth, but, because the end axle is longer with pipe assembling coordinating size, the welding procedure difficulty is bigger, and is yielding; The position of stiffening web has a significant impact the size of granulation particle diameter, if stiffening web is in the top of stirring tooth, its particle diameter is thin more, causes line clogging when mixing easily; If stiffening web is in the bottom of stirring tooth, its particle diameter is big more, broken easily when drying, and the granulation axle of existing structure, the position of its stiffening web all is arranged on the top of stirring tooth, the granulation weak effect, and stirring tooth can wear and tear in use for some time, the gap of stirring between tooth and the shell is strengthened, and its position of stirring tooth of the granulation axle of existing structure can not be regulated, and also can influence the granulation effect; When pipe diameter was big, three spirals stirred the quantity not sufficient of gear mechanism, and stirring intensity is not enough.

The utility model content

The purpose of this utility model provides a kind of wet granulator, can overcome the granulation axle manufacturing process complexity of existing wet granulator, the shortcoming of granulation weak effect.

The purpose of this utility model is achieved in that wet granulator comprises the granulation axle; this granulation axle is by pipe; be fixed on the end axle at pipe two ends; be fixed on the screw-blade on the pipe; be fixed on the ratch that stirs of pipe; be installed in each and stir stirring tooth and being fixed on each stiffening web that stirs on the tooth and forming on the ratch; the part that each end axle and pipe cooperate respectively is processed into the above ladder of two-stage; on the different ladder of end axle, plural retaining ring is installed; by holding axle to fixedly connected with the end axle with the pipe welding respectively retaining ring with pipe; as long as the spacing of outermost two retaining rings is enough; just can guarantee the intensity of granulation axle; shortened the zone of welding procedure on the other hand widely; be out of shape little; good manufacturability is saved material again.

As further improvement of the utility model, described stir ratch be uniformly be fixed on tube surface, several of the above helical arrangement of four-head stir ratch at least, to satisfy the needs of big-inch pipe.

As further improvement of the utility model, stir tooth and stir ratch by being threaded, stir the position of tooth by adjustment, thereby control its granulation effect.

As further improvement of the utility model, stiffening web is fixed on apart from stirring the 20-50 of tooth top portion millimeter place, further controls its granulation effect.

Advantage of the present utility model is: under the situation of the intensity that guarantees its granulation axle, simplified manufacturing process, lowered manufacturing cost, saved material, improved the granulation effect.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

By shown in Figure 1, the granulation axle of the utility model wet granulator comprises two end axles 1, pipe 2, screw-blade 3, stir ratch 6, stir tooth 7 and stiffening web 8, the part that each end axle 1 stretches into pipe is processed into three grades of ladders, correspondingly, the internal surface of two tube heads of pipe 2 also is processed into three grades of ladders, assembling and positioning ring 4 on first ladder of end axle 1, assembling and positioning ring 5 on the 3rd ladder, second ladder is non-mating surface, can be rough turn, retaining ring 4,5 weld with end axle 1 and pipe 2 respectively, thereby two end axles 1 and pipe 2 are coupled as one, can shorten coordinating size again, be convenient to welding procedure; Also be welded with on the pipe 2 two groups of uniform screw-blades 3 and uniform, by a plurality of ratch 6 that stir of five helical arrangement, shown in Fig. 2,3, each stir ratch 6 by screw thread with stir tooth 7 and be connected, and it is fixing with nut 9, locate welding and fix a stiffening web 8 for 20 millimeters at the top of stirring tooth 7 apart from each, like this, increase the number of teeth amount of stirring, can increase stirring intensity, be applicable to big-inch pipe; Stir tooth 7 and stir tooth 7 and shell gap with stirring ratch 6 for flexibly connecting, can regulating, allow stiffening web 8 be in suitable position, its particle diameter is even, is of moderate size.

Fig. 4 and Fig. 5 are two kinds of embodiments in addition of the present utility model, and stiffening web 8 is weldingly fixed on respectively apart from top 35 and 50 millimeters places of stirring tooth 7.
