Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a dry oil pump granulator. Background Art

[0002] A granulator is a device that prepares powdered materials into granular materials. It is equipped with a pressing wheel and a mesh mold for extruding materials, as well as a scraper for cutting materials into granules. It is mainly used in the fields of pharmaceuticals, chemicals, and food.

[0003] The scraper of the traditional granulator is fixed by screws. During installation, it is necessary to ensure that the scraper is completely fixed on the granulator and that it is close to the surface of the mesh mold. Since there is no positioning structure to assist the scraper during installation, it is difficult to position it. It is time-consuming and laborious to install or regularly replace the scraper, causing certain inconveniences. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a dry oil pump granulator, including an outer shell, a main motor, a supporting tray, a material-discharging motor, a feed cover, a mesh mold, a pressure wheel component and a scraper component, the two ends of the outer shell are respectively connected to the main motor and the supporting tray, the supporting tray is detachably connected to the feed cover, one side of the supporting tray is connected to the material-discharging motor, and the supporting tray is coaxially distributed with the mesh mold, the pressure wheel component is arranged on the inner side of the mesh mold, the supporting tray and the mesh mold are combined to form an extrusion chamber and a granulation chamber, the pressure wheel component is arranged in the extrusion chamber, and the scraper component is arranged in the granulation chamber, the main motor simultaneously drives two groups of pressure wheel components to rotate and connect to the supporting tray, the material-discharging motor drives the mesh mold to rotate and connect to the supporting tray, and positioning blocks distributed in a circle are arranged around the supporting tray, and the scraper component is connected to the supporting tray through the positioning blocks.

[0005] By adopting the above technical scheme, the main motor drives the pressure wheel to rotate through the connection mode of the pulley, and the material feeding motor drives the mesh mold to rotate through the gear transmission mode. The powder material enters the extrusion chamber, is squeezed by two sets of pressure wheels and causes the powder material to undergo physical changes or appropriate chemical changes under high temperature and high pressure. The material is squeezed into a long cylindrical solid body by the mesh mold. The mesh mold rotates relative to the scraper member, and the scraper member cuts the material into granular material, which is driven by the mesh mold to be discharged from the support tray. The scraper member is installed on the support tray through the positioning block. While the scraper member is easy to replace, the length of the cut granular material can be determined according to the number of scraper members. That is, the more scraper members there are and the denser the distribution is, the shorter the length of the granular material is, which makes the granulator have a wide range of applications.

[0006] The utility model is further configured such that the support tray is provided with an outer ring portion, the positioning blocks are distributed circumferentially above the outer ring portion, the scraper member is provided with a mounting portion and a cutter head portion, the scraper member is clamped between adjacent positioning blocks through the mounting portion, and the cutter head portion is arranged on the outer side surface of the mesh mold.

[0007] Furthermore, the outer ring portion is provided with a threaded hole, the scraper member is provided with a long hole matched with the threaded hole, and the scraper member is threadedly connected to the outer ring portion through the threaded hole.

[0008] Furthermore, the mesh mold is provided with a mesh surface and transmission teeth, the cutter head is in contact with the outer side of the mesh surface, and the material-discharging motor drives the mesh mold to rotate relative to the supporting tray via the transmission teeth.

[0009] By adopting the above technical solution, the scraper member is formed into an L-shaped mounting portion and a cutter head through a bending process. The spacing between adjacent positioning blocks is equal to the width of the mounting portion, which is convenient for positioning the scraper member. The distance between the cutter head and the mesh mold is adjusted through the long hole to avoid squeezing and mutual wear between the cutter head and the mesh mold.

[0010] The utility model is further configured that mounting holes are arranged around the feed cover, the feed cover is sleeved on the outer ring portion and abuts against the positioning block, and the feed cover is connected to the support tray through bolts in the mounting holes.

[0011] Furthermore, the feed cover is provided with an inlet and an exhaust port which are connected to the extrusion chamber, and the outer ring portion is provided with an outlet which is connected to the granulation chamber.

[0012] By adopting the above technical solution, the upper surface of the positioning block is higher than the bolt. When installing the feed hood, the feed hood preferably abuts against the positioning block to avoid the feed hood from tilting, which is convenient for positioning and installation. The exhaust port is used to discharge the high-temperature gas in the extrusion chamber to avoid the moisture in the gas from corroding the components inside the feed hood and improve the service life of the equipment.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The material is squeezed into a long cylindrical solid body by two sets of pressing wheels and mesh molds, the material is cut into granular materials by the scraper, and the granular materials are driven by the mesh mold to be discharged from the tray. The granulation method is simple and the structure is stable;

[0015] 2. The scraper parts can be replaced by positioning blocks, which improves the convenience of replacing the scraper parts. The length of the cut granular material can be determined according to the number of scraper parts, making the granulator have a wide range of applications.
