Problems solved by technology

Therefore, the force between the pressure roller assembly and the ring die is transmitted to the box through the safety pin seat and the safety pin at one end of the main shaft during work, so that the rear end of the main shaft is supported, but the front end of the main shaft cannot be supported. This structure makes the main shaft jump up and down greatly, and the working state is unstable; moreover, due to the uneven distribution of the incoming material, the inconsistent thickness of the material layer will also cause the main shaft to jump up and down, and the working state is unstable; this aspect affects the product quality of granulation Stability. On the other hand, the main shaft has a short service life and is easy to break. Due to the high price of the main shaft, this leads to an increase in the cost of use and poor safety in use.
In addition, once the main shaft breaks, it will be stopped for replacement, which also causes a large loss to production.
[0004] (2) The material feeding is not smooth, and it is easy to arch and block the material
At present, the material of the ring die granulator is fed into the die cover by the forced feeder, and then the material is fed into the pressing chamber through the feeding scraper. There is no thrust effect. In addition, the die cover, feeding scraper, and spindle head block the material. If the material is blocked in the pressing room, it can be blocked all the way to the forced feeder. The thrust of the forced feeder acts on the feeding scraper, spindle head, etc. to block the material. Therefore, for loose, low-density, and poor-flowing materials, the existing ring die granulators are very easy to jam, arch, and block materials, and insufficient feed often occurs at the feed port. The phenomenon of arching and blocking materials occurs from time to time, which brings considerable difficulties to granulation, which greatly affects the production efficiency, causes high production costs, and brings great inconvenience to p...

Embodiment 1

[0024] Such as figure 1 and figure 2 as well as Figure 5 to Figure 7 As shown, a ring die granulator includes a granulator host 1, a host safety pin seat 2, a safety pin 3, a ring die 4, a hoop 5, a transmission wheel 6, a bearing 7, a main shaft 8, and an empty shaft of the host 9. Press roller assembly 10, spindle press plate 13, cutter 28 and door cover 16, also includes gear shaft 26 connected with power, also includes forced feeder 17, material inlet 21 and material outlet 22 , also includes a partition plate 14 and a door cover pressing plate 15, and also includes a mold roller gap adjustment mechanism 31. One end of the door cover 16 is connected with the box body 1-1 of the main machine 1 of the granulator through a door hinge 19, and the other end is connected with the box body 1-1 through a door lock 12. The discharge port 22 is arranged at the lower end of the door cover 16 . The door cover 16 can rotate around the casing 1-1 of the granulator host 1 through a...

Embodiment 2

[0028] Such as image 3 and Figure 4 as well as Figure 5 to Figure 7 As shown, a ring die granulator, the structure of the ring die granulator of this embodiment is basically the same as that of Embodiment 1, the difference is: (1) the upper feed port 21-1 and the lower feed port 21 -2 Compulsory feeders 17 are arranged at the opposite places of the two feeding ports. That is to say, the ring die granulator in this embodiment is provided with two forced feeders 17, one forced feeder 17 is opposite to the upper feed inlet 21-1, and the other forced feeder 17 is connected to the lower feeder. Mouth 21-2 relative. The two forced feeders 17 can force feed the pressing chamber through the two feeding ports 21 at the same time, so that the production efficiency is greatly improved. (2) The eccentric shaft 25 of the pressure roller is connected to the gap adjustment wheel 24 through a gear type, and the central shaft 20 and the center wheel 23 are also connected through a splin...

Abstract

The invention relates to a circular mold pelletizer and especially relates to a circular mold pelletizer for biomass pelletizing. The circular mold pelletizer comprises a main machine (1), a circular mold (4), a driving wheel (6), a main shaft (8), a main machine hollow shaft (9), a roller assembly (10), a main shaft pressing plate (13), slicers (28), a door cover (16), a gear shaft (26), forced feeders (17), feed inlets (21) and a discharge outlet (22). The circular mold pelletizer also comprises a division plate (14) and a door cover pressing plate (15), wherein the division plate (14) is connected to the main shaft pressing plate (13) at an end of the main shaft (8); the door cover pressing plate (15) is arranged at an inner side of the door cover (16); and the door cover pressing plate (15) and the division plate (14) are movably connected together. The circular mold pelletizer has the advantages that the circular mold pelletizer has a simple structure; a front end of the main shaft (8) is supported; the main shaft (8) moves up and down in a small range and has a long service life; raw material feeding is smooth; arch forming and material blocking are produced difficultly; adjustment of a roller-mold gap is convenient; and an overload protection capacity is strong.

Description

technical field [0001] The invention relates to a ring die granulator, in particular to a ring die granulator mainly used for biomass granulation. The invention is suitable for making pellets from materials in various industries such as feed, grain, food, chemical industry, medicine, fertilizer, etc., especially for biomass production such as wood chips, straw, bamboo chips, cotton wood particles, hops, and agricultural waste. grain. The invention belongs to the technical field of particle forming processing equipment. Background technique [0002] As a very mature traditional pellet forming and processing equipment, the ring die pellet mill is also an important pellet forming and processing equipment that is widely used and indispensable. The physical and biochemical properties of materials can be changed by ring die granulator to meet the needs of feed, grain, food, chemical, pharmaceutical, fertilizer and other industries for granulated materials. The main working par...
