Problems solved by technology

This process mainly has the following disadvantages: 1) The motor power of the refrigerating unit is large and the energy consumption is too high, 2) The refrigerating unit occupies a large area, 3) The large size of the wax block causes inconsistent cooling speed and easily causes cracks and depressions
Although this technical solution optimizes the original granulation process to a certain extent, since the softening point of paraffin wax is around 55°C, it is difficult for the paraffin extruded by a conventional extruder to be cooled and shaped in a short time when screw extrusion is used for granulation. , after being cut off, they will stick together and form a group, which makes granulation impossible
[0005] In addition, the invention patent application with the application publication number CN103358417A provides "a granulation process method for a mixture of rosin, paraffin, and potassium chloride with a low softening point". The crushed rosin, paraffin, and potassium chloride are mixed according to a certain weight ratio; the mixed material is put into a vertical extruder and extruded into strips, and the extruded strips are first air-cooled; the air-cooled materials fall on the rotating steel Then carry out water cooling on the belt; the fully cooled strip material is shaped by a shaping machine. This method uses an extruder to extrude the strip and cool it on the steel belt before cutting it. The granulation of potassium chloride inorganic salt improves the uniformity of the granules, but because the cooling efficiency is too low, the steel belt must be lengthened, which still cannot avoid the problem that the floor area is too large

Abstract

The invention relates to a granulating device and method for paraffin, and fundamentally solves the problems that an existing paraffin granulating device is large in floor occupation area, low in operation efficiency and the like. The granulating device comprises a feeding mechanism, a forming mechanism and a cutting mechanism, wherein the cutting mechanism comprises a cutter rotating shaft, and a plurality of cutters which are arranged on the cutter rotating shaft. According to the technical key point, the cutter rotating shaft is limited on the center of a guide plate by virtue of a bearing, and the cutters are arranged on the bottom of the guide plate; a lower supporting shell is fixed on the guide plate, a conical template and a supporting plate are limited in the lower supporting shell, the conical template comprises a distribution cone on the center and a flange structure on the bottom of the distribution cone, and a conical cover which is fixed on the supporting plate and distanced to the conical template is arranged between the conical template and the supporting plate; the flange structure is circumferentially provided with a plurality of forming guide plates, and a plurality of discharging holes corresponding to discharging openings of the forming guide plates are circumferentially formed in the guide plate.

Description

technical field [0001] The invention relates to a granulation equipment and method, which are applied to the granulation of simple substances or mixtures that are solid at normal temperature and relatively low in softening point and melting point, especially for paraffin wax granulation. Background technique [0002] At present, paraffin transportation is generally in the solid state, usually in the form of blocks or granules. Among them, in the production process of the existing block paraffin continuous molding machine, a refrigeration unit is used to provide a cold source in conjunction with the molding machine, so that it gradually condenses from a liquid state into a solid wax block. This process mainly has the following disadvantages: 1) the motor power of the refrigerating unit is large and the energy consumption is too high, 2) the refrigerating unit occupies a large area, and 3) the large size of the wax block causes inconsistent cooling speed and easily causes crac...
