Description

Technical Field

[0001] This utility model relates to the field of roller granulator technology, specifically to a roller granulator feed unblocker. Background Technology

[0002] In the extrusion granulation process of fertilizer production, fertilizer raw materials, such as ammonium sulfate, exhibit a significant increase in viscosity after the addition of water. When these high-viscosity raw materials enter the extrusion granulator inlet, they are highly susceptible to accumulation and blockage due to their poor flowability, severely impacting the normal operation and production efficiency of the granulator.

[0003] Currently, the industry primarily uses manual methods to address the aforementioned blockage issues. One method involves directly poking the material with a stick to clear the blockage. However, this method has significant drawbacks. Because the depth of the stick insertion and the force applied are difficult to control precisely, it easily damages the rollers below the extrusion granulator inlet, affecting granulation and increasing maintenance costs. Another method involves tapping the feed inlet to dislodge the blockage through vibration. This method is prone to deforming the feed inlet structure.

[0004] Therefore, it is necessary to propose a feed unblocking device for a double-roll granulator to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this utility model is to provide a feed unblocking device for a roller granulator that has a good unblocking effect and will not damage the equipment, so as to solve the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a feed unblocker for a roller granulator, comprising a rectangular funnel, wherein hooks are symmetrically fixedly connected to two sides of the rectangular funnel, and side plates are symmetrically fixedly connected to the other two sides of the rectangular funnel, and a discharge port is inclined at the bottom end of the rectangular funnel along its width direction. A drain rod runs through the interior of the rectangular funnel. The drain rod is arranged along the side wall of the lower side of the discharge port. A limit block is fixedly connected to the outside of the drain rod. A limit cylinder is provided at the top of the rectangular funnel. The limit cylinder and the limit block cooperate to limit the sliding of the drain rod.

[0007] Preferably, the limiting cylinder is sleeved on the outside of the unblocking rod, and the diameter of the limiting block is larger than the inner diameter of the limiting cylinder.

[0008] Preferably, a slider is fixedly connected to the outside of the limiting cylinder, and the slider reciprocates along the length of the rectangular funnel.

[0009] Preferably, a limiting frame is fixedly connected to the top of the rectangular funnel along its length, and grooves are provided on both sides of the slider, and the slider is slidably connected to the limiting frame through the grooves.

[0010] Preferably, the rectangular funnel is attached to the feed inlet of the granulator via a hook.

[0011] Preferably, the discharge port of the rectangular funnel corresponds to the gap between the rollers of the granulator.

[0012] Preferably, the hook is arranged in a direction corresponding to the axial direction of the roller, and the length of the hook is the same as the length of the rectangular funnel.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a feed unblocking device for a roller granulator, which has the following beneficial effects: 1. The feed unblocking device for this double-roll granulator is equipped with a rectangular funnel and an inclined discharge port below the rectangular funnel. Under the action of the discharge port, the material can be accurately conveyed to the gap between the double rolls, preventing the material from overflowing from the roll edge.

[0014] 2.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1-5 As shown, a feed unblocking device for a roller granulator includes a rectangular funnel 1. Hooks 8 are symmetrically fixedly connected to two sides of the rectangular funnel 1, and side plates 5 are symmetrically fixedly connected to the other two sides of the rectangular funnel 1. A discharge port 6 is inclined at the bottom end of the rectangular funnel 1 along its width direction. A unblocking rod 2 passes through the interior of the rectangular funnel 1 and is arranged along the side wall of the lower side of the discharge port 6. A limiting block 7 is fixedly connected to the outer side of the unblocking rod 2. A limiting cylinder 9 is provided at the top of the rectangular funnel 1. The limiting cylinder 9 cooperates with the limiting block 7 to limit the sliding of the unblocking rod 2. Specifically, the rectangular funnel 1 is hooked to the feed port 12 of the granulator 11 via the hooks 8, and the discharge port 6 of the rectangular funnel 1 corresponds to the gap of the rollers 10 of the granulator 11.

[0019] In use, the rectangular funnel 1 is placed inside the feed inlet 12 of the granulator 11, and the hook 8 is attached to the edge of the feed inlet 12. Material is fed into the granulator 11 through the rectangular funnel 1. Under the action of the discharge port 6, the material is accurately conveyed to the gap between the rollers 10, preventing material from overflowing from the roller edges. When material in the rectangular funnel 1 becomes clogged, the reciprocating sliding unblocking rod 2 clears the discharge port 6. Because the discharge port 6 is inclined and the unblocking rod 2 is located on the lower side of the discharge port 6, the cleared material will flow to the higher side of the discharge port 6 and be discharged under its own weight and the pushing action of the unblocking rod 2, improving the unblocking effect. By setting a limiting block 7 and a limiting cylinder 9, the range of motion of the unblocking rod 2 is limited to control the distance between the bottom end of the unblocking rod 2 and the rollers 10, preventing the unblocking rod 2 from damaging the outer roller skin of the rollers 10 and affecting granulation. A side plate 5 is provided for easy placement and removal of the rectangular funnel 1.

[0020] To enable the drain cleaner 2 to clear different locations in the discharge port 6, a slider 3 is fixedly connected to the outside of the limiting cylinder 9. The slider 3 reciprocates along the length of the rectangular funnel 1. Specifically, the limiting cylinder 9 is fitted onto the outside of the drain cleaner 2, and the diameter of the limiting block 7 is larger than the inner diameter of the limiting cylinder 9. When the position of the drain cleaner 2 needs to be adjusted, slide the drain cleaner 2 upwards to disengage it from the material, then slide the limiting cylinder 9 to the area to be cleared, and then slide the drain cleaner 2 back and forth to clear the discharge port 6. Under the action of the limiting cylinder 9, when the drain cleaner 2 is pulled out, the material on the outside of the drain cleaner 2 can be scraped off, preventing material from adhering to the outside of the drain cleaner 2.

[0021] Specifically, the top of the rectangular funnel 1 is fixedly connected to the limiting frame 4 along its length direction, and the slider 3 has a sliding groove 13 on both sides. The slider 3 is slidably connected to the limiting frame 4 through the sliding groove 13, which can limit the tilt angle of the limiting cylinder 9 and prevent the change of the tilt angle of the unblocking rod 2 from affecting the unblocking effect. At the same time, its structure is simple and easy to assemble.

[0022] Specifically, the direction of the hook 8 corresponds to the axial direction of the roller 10, and the length of the hook 8 is the same as the length of the rectangular funnel 1. The design of the long hook 8 allows the weight of the rectangular funnel 1 and the material inside it to be evenly transferred to the feed inlet 12 along the entire length of the hook 8, increasing the contact area of ​​the force and avoiding structural damage to the rectangular funnel 1 due to stress concentration.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
