Description

Technical Field

[0001] The utility model relates to the technical field of feed manufacturing equipment, in particular to a high-efficiency and energy-saving twin-screw extruder. Background Art

[0002] Expanded pellet feed is a kind of fluffy and porous pellet feed made by feeding powdered and granular feed raw materials into an expander, and then going through a series of processes such as continuous mixing, conditioning, heating, pressurizing, extruding out of a die hole, sudden pressure reduction, cutting into small pieces, and drying. The expanded feed has foaming porosity, small specific gravity, and can float on the water surface for a period of time, making it suitable for use as aquatic feed. Expanding equipment is needed in the preparation of aquatic feed.

[0003] When using traditional puffing equipment, the raw materials of the feed need to be mixed with steam before entering the puffing chamber, so as to improve the maturation rate and puffing properties of the raw materials. After the raw materials come into contact with the steam, they will stick together. Traditional equipment directly puts the raw materials into the puffing bin after mixing them with the steam, which will cause large pieces of raw materials to enter between the screws, resulting in uneven amount of raw materials contacted by the outer wall of the screw. The accumulation of large pieces of raw materials will lead to incomplete puffing, which will affect the quality of the feed. Utility Model Content

[0025] A lower silo 4 is installed on the top of the puffing silo 2, and a No. 1 crushing rod 7 and a No. 2 crushing rod 10 are rotatably connected in the inner cavity of the lower silo 4. The No. 1 crushing rod 7 can rotate under the action of the driving motor 5 and the driving belt 6. At the same time, during the rotation of the No. 1 crushing rod 7, the No. 2 crushing rod 10 can be driven to rotate under the action of the driving gear 8 and the driven gear 9, thereby breaking up the materials passing through the lower silo 4.

[0026] In a preferred embodiment, the outer wall of the driving belt 6 away from the driving motor 5 is rollingly connected to the outer wall of the No. 1 crushing rod 7, and the driving belt 6 is made of vulcanized rubber.

[0027] By respectively setting a No. 1 crushing rod 7 and a No. 2 crushing rod 10 in the inner cavity of the lower material bin 4, and the No. 1 crushing rod 7 and the No. 2 crushing rod 10 can rotate at high speed under the action of the driving motor 5, and the rotation direction of the No. 2 crushing rod 10 is opposite to the rotation direction of the No. 1 crushing rod 7, the No. 1 crushing rod 7 and the No. 2 crushing rod 10 can fully break up the raw materials passing through the lower material bin 4.

[0030] In a preferred embodiment, the outer wall diameter of the connecting rod 14 matches the inner wall diameter of the fixing seat 11 , and the outer wall diameter of the discharge plate 15 matches the inner wall diameter of the puffing bin 2 .

[0031] By installing a connecting rod 14 in the inner cavity of the fixing seat 11, and fixing the connecting rod 14 to the inner cavity of the fixing seat 11 through the limiting rod 12 and the cam 13, the discharge plate 15 is fixedly installed in the inner cavity of the puffing bin 2 under the action of the connecting rod 14, so that the puffed feed is extruded and formed under the action of the discharge plate 15.

[0032] In a preferred embodiment, the limiting rod 12 is installed at a position above the center of the cam 13 , and an operating rod is fixedly mounted on the outer wall of the cam 13 .

[0033] By rotating the connected cam 13 on the outer wall of the limiting rod 12, and the circle of the cam 13 is not in the same position as the limiting rod 12, when the cam 13 is rotated, the cam 13 can rotate along the outer wall of the limiting rod 12, so that the outer wall of the cam 13 presses the outer wall of the connecting rod 14 during the rotation process, thereby fixing the connecting rod 14 in the inner cavity of the fixing seat 11.

[0034] In a preferred embodiment: a limit plate is installed on the outer wall of the end of the connecting rod 14 away from the fixing seat 11 , and the power output shaft of the driving motor 16 is connected to the outer wall of the first extrusion screw 17 .

[0035] By installing a limiting plate on the outer wall of the connecting rod 14, when it is necessary to install the discharge plate 15 on the outer wall of the base 1, the connecting rod 14 is fixedly installed in the inner cavity of the fixing seat 11, thereby fixing the connecting rod 14. At this time, the discharge plate 15 is fixed in the inner cavity of the puffing bin 2 under the action of the limiting plate on the outer wall of the connecting rod 14.

[0036] In a preferred embodiment, there are four fixing seats 11 , and the four fixing seats 11 are evenly installed on the outer wall of the puffing bin 2 .

[0037] By setting four fixing seats 11 on the outer wall of the puffing bin 2, the four fixing seats 11 can fix the four connecting rods 14, so as to fix the discharge plate 15 from four directions, so as to better ensure the stability of the discharge plate 15 when in use and better discharge.

[0039] By setting a controller in the inner cavity of the equipment bin 3, the driving motor 5 and the driving motor 16 can be controlled separately under the action of the controller, so that the driving motor 5 can better drive the rotation of the No. 1 crushing rod 7, thereby better breaking up the raw materials passing through the lower bin 4.

[0040] Working principle: During the use of the above-mentioned equipment, when the equipment needs to be used to make feed, the driving motor 5 is first started through the controller, so that the driving motor 5 drives the rotation of the No. 1 crushing rod 7, thereby driving the rotation of the No. 2 crushing rod 10 during the rotation of the No. 1 crushing rod 7. At this time, the rotation directions of the No. 1 crushing rod 7 and the No. 2 crushing rod 10 are opposite, so that the No. 1 crushing rod 7 and the No. 2 crushing rod 10 break up the raw materials during the rotation. When the raw materials pass through the lower bin 4 and enter the inner cavity of the puffing bin 2, the raw materials can be puffed during the rotation and rolling of the No. 1 extrusion screw 17 and the No. 2 extrusion screw 18. The raw materials continue to move forward in the inner cavity of the puffing bin 2. When the raw materials move to the outlet of the puffing bin 2, the raw materials will come out of the inner cavity of the puffing bin 2 through the discharge plate 15 and be formed under the action of the discharge plate 15.
