Description
Technical Field
The utility model relates to a stir the tooth stirring and carry and rub the horizontal wet process granulator that causes graininess with the powdery material with the hands with a section of thick bamboo wall through stirring on the (mixing) shaft, the granulator is by transmission, barrel subassembly and three major parts of stirring axle subassembly are constituteed, for guaranteeing that the granulator carries the material in-process smooth operation, do not have great vibration, install these three major parts subassembly on same base under the usual condition, the base is fixed with equipment foundation anchor bolt connection, this ZLJ type wet process granulator comprises two major parts, transmission and granulation conveyor promptly. The mounting precision is ensured, the stress condition of the stirring shaft of the granulator is improved, the vibration of the equipment is reduced, and the structure is more compact and the occupied area is small.
Background
The wet granulator widely used in the fields of chemical industry, chemical fertilizers, ores, electric power, carbon black and the like is characterized in that powdery materials are added with granulating water and are distributed on a stirring shaft of the granulator to form wet granules between spiral stirring teeth and an inner cylinder wall, a conveying cylinder of the granulator is of a jacket structure and has steam heat tracing, the length of the cylinder is 3.2-3.5 meters, the diameter of the cylinder is 0.5-1.2 meters and other types, and the materials are granulated by spraying the granulating water into the cylinder and then are conveyed to a following drying device from a discharge port to be dried. The bearing blocks at the two ends of the stirring shaft are connected with the base through the bearing supports, the barrel support is arranged on the base, the transmission device is directly arranged on the base plate, and the base is a steel structure assembly welding piece, so that the base is required to be strong in rigidity, high in strength and not deformed, and the flatness or parallelism of the mounting surface of each part arranged on the base is required to be within a required range, and the purposes of stable operation and small vibration of the granulator can be achieved.
The pelletizer equipment has been mounted on the same base using three large components as is conventional. The mounting process requires that the mounting surfaces of the three major components are required to be on the same plane when the base is mounted on a foundation, and the relative positions are ensured to meet the technical requirements. The motor forms a transmission device with a big belt pulley on the stirring shaft through a small belt pulley, a belt, the cylinder support is arranged on the base, and the bearings at the two ends of the stirring shaft are arranged on the base through the bearing block and the bearing support. The whole equipment installation process is very troublesome, especially the installation of barrel support and (mixing) shaft bearing support, and the requirement of two parts subassembly axiality is hardly guaranteed in the respective fixed mounting of (mixing) shaft and barrel, easily produces great vibration in the equipment operation process, stirs tooth and barrel inner wall clearance inhomogeneous, seriously influences the granulation effect or causes and scrapes the wall. Under actual working conditions, the maintenance cycle of the granulator is short and the granulator is frequently stopped for rush repair, so that the normal operation of the production line is seriously influenced, and enterprises suffer from economic loss.
Traditional wet granulator installation theory of operation: before the granulator leaves a factory, the stirring shaft and the barrel are assembled together, and then bearing blocks at two ends and a large belt pulley are installed and fixed for protection. Fix and make level the alignment with the rag bolt of equipment foundation earlier on the scene, the bolt is good for the bearing support of installation on the base, (mixing) shaft and bearing frame hoist and mount together on the base together with the barrel support, the bearing frame is installed on the bearing frame support, the barrel support mounting is on the base, transmission installs on the base, couple big belt pulley and small belt pulley with the belt, adjust each fastener of partial subassembly of each, start trial run readjustment is up to meeting technical requirement, its characterized in that: the stirring shaft and the barrel are arranged on the base through the barrel support, bearings at two ends of the stirring shaft are arranged on the base through the bearing seats and the bearing supports, the transmission device is connected with the stirring shaft through the belt pulley system and is arranged on the base plate, and the base is arranged on the equipment foundation as a whole so as to meet the requirement of fixing the relative positions of the stirring shaft and the barrel.
The disadvantages are that:
the stirring shaft and the barrel are respectively installed on the base, the stirring shaft is in contact with and rotates with a sealing box on a barrel end cover, the barrel is restricted by a barrel support, the stirring shaft is restricted by a bearing support, and the stirring shaft generates eccentric wear to a sealing element after deviation is generated in installation, so that material leakage and environment pollution are caused, the installation precision is high between the stirring shaft and the barrel, and the coaxiality is guaranteed within the tolerance requirement range.
Secondly, the granulator needs to be subjected to type tests before leaving a factory, bearing blocks at two ends are fixed by tools or are independently sent to the site for reassembly during delivery, the state of trial run before leaving the factory is hardly guaranteed by a stirring shaft and a barrel, and vibration and noise are large in the operation process of site feedback equipment.
The stirring shaft is rigidly connected with the base through the bearing support, the barrel is rigidly connected with the base through the barrel support, the stirring shaft rotates in the barrel, no relative positioning reference exists between the stirring shaft and the barrel, the coaxiality of the installed stirring shaft cannot be guaranteed, and large errors can be formed due to the accumulation of installation errors of all parts and cannot be adjusted.
And fourthly, the clearance between the stirring teeth on the stirring shaft and the inner wall of the cylinder body is very small, the eccentricity caused by installation not only can prevent the granulation effect from meeting the process requirement, but also the stirring teeth and the cylinder wall form zero clearance to be mutually worn or wear through the cylinder body.
And fifthly, the stirring shaft bears the effects of axial force, torque and bending moment in the operation process, the distance between the bearing supports at two ends is too long, generally about 4 meters, the eccentric distance of the stirring shaft is continuously increased under the action of the bending moment and tends to bend and deform, the amplitude of equipment and the abrasion to a sealing piece are increased, and potential safety hazards exist on site to equipment and operators.
Sixthly, when the stirring teeth are replaced, the stirring shaft is drawn out, the end cover of the cylinder body and the bearing support are disassembled, the stirring shaft is re-assembled after replacement, and the bearing support cannot be leveled and aligned again after more than two times of re-assembly, so that the equipment maintenance period is shorter and shorter.
Seventhly, the gland of the sealing box is dismantled when the sealing packing is replaced, the bearing support is installed besides leaving enough space between the bearing support and the end cover of the barrel, so that the length of the base is increased, the space of the discharge port for an external connecting pipeline is small, the occupied area of a granulator is large, the production line is long, the production land is wasted, and the input cost is increased.
Therefore, there is a need to develop a wet granulator which has compact structure, high installation accuracy, convenient maintenance and small occupied area.
