Description

Technical Field

[0001] The utility model belongs to the technical field of feed processing equipment, and particularly relates to an air inlet structure of a granulator. Background Art

[0002] In order to optimize the forming quality of feed and the uniformity of products, existing feed granulators are generally equipped with a conditioner. The conditioner can uniformly mix various components in the feed raw materials. Before entering the granulator, the conditioner can pre-treat the feed raw materials, such as pre-heating and humidifying, to improve the plasticity and formability of the feed raw materials, which is beneficial to the formation and stability of granules. Currently, the common practice is to introduce steam into the conditioner, but the existing steam inlet is relatively single, generally directly introduced from below or the lower side, which cannot achieve sufficient mixing with the feed and affects the product quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide an air inlet structure of a granulator.

[0004] The utility model is realized by the following measures:

[0005] In the first aspect, this embodiment provides an air inlet structure of a granulator, which is characterized in that it includes a steam distribution pipe arranged outside the conditioning cylinder of the granulator. The axis of the steam distribution pipe is parallel to the axis of the conditioning cylinder. The upper part of the steam distribution pipe is communicated with the upper part inside the conditioning cylinder through a plurality of upper air pipes, and the lower part of the steam distribution pipe is communicated with the lower part inside the conditioning cylinder through a plurality of lower air pipes. The upper air pipes are close to the feed inlet located in the upper part of the conditioning cylinder, and the lower air pipes are located between the upper air pipes and the discharge port of the conditioning cylinder;

[0006] Each of the lower air pipes and each of the upper air pipes are provided with branch control valves, and the steam distribution pipe is connected to a steam source through a pipeline and is provided with a main control valve.

[0007] Both the upper air pipes and the lower air pipes are provided with 4 - 8 pieces.

[0008] The steam distribution pipe is fixed on the outer wall of the conditioning cylinder through a plurality of support plates.

[0009] The axis of the steam distribution pipe and the axis of the conditioning cylinder are on the same horizontal plane.

[0010] Each of the support plates is provided with a mounting hole, a connecting rod is arranged in the mounting hole, and a plurality of thread segments corresponding to the upper air pipes and the lower air pipes one by one are arranged on the connecting rod;

[0011] A support rod is sleeved on the threaded section and fixed by nuts arranged on both sides of the support rod. An installation plate is arranged on the support rod, and pipe clamps sleeved on the upper air pipe and the lower air pipe are arranged on the installation plate. A rubber ring is arranged between the inner wall of the pipe clamp and the outer wall of the air pipe.

[0012] The pipe clamp includes two symmetric semi-circular ring plates. The rubber ring is formed by splicing two semi-circular structures. The inner wall and both end walls of the semi-circular ring plate wrap the rubber ring.

[0013] The two semi-circular ring plates are connected by bolts.

[0014] A stud is fixedly arranged at the bottom of the lower semi-circular ring plate, and the stud is fixed on the installation plate by a nut.

[0015] In a second aspect, a granulator is provided in this embodiment, which is characterized by including the air intake structure of the granulator.

[0016] The granulator includes a feed cylinder located above the conditioning cylinder. A conveying auger is rotatably arranged in the feed cylinder. A filling port is arranged at the upper part of one end of the feed cylinder, and a discharge port communicating with the feed port is arranged at the lower part of the other end of the feed cylinder.

[0017] A stirrer is rotatably arranged in the conditioning cylinder. The stirring shaft of the stirrer is a hollow rod, and a plurality of ventilation holes are arranged through the side wall of the hollow rod, so that steam can penetrate the stirring shaft, further improving the mixing of steam and feed.

[0018] The beneficial effects brought by the technical solution provided by the embodiment of the present utility model are as follows: The conditioning cylinder of the granulator is provided with an upper air pipe and a lower air pipe. The feed entering the conditioning cylinder first passes through the upper air pipe section and then through the lower air pipe section, so that the feed in the conditioning cylinder is fully mixed with steam. Since there are multiple upper air pipes and lower air pipes, in order to avoid the influence of the vibration of the granulator on the air pipes, pipe clamps are arranged and rubber rings are wrapped in the pipe clamps. One is to limit the air pipes, and the other is to absorb vibration when vibration occurs. BRIEF DESCRIPTION OF THE DRAWINGS
