Description

Technical Field

[0001] The utility model relates to the field of pellet feed production equipment, in particular to a post-ripening device for aquatic pellet feed. Background Art

[0002] The preparation process of pellet feed generally involves initial crushing of raw materials, primary mixing, ultrafine grinding, secondary mixing, conditioning, storage, pelleting, cooling, screening, and packaging. In practice, to improve the gelatinization degree of the pellet feed, a post-ripening process can be added after pelleting. Prior art equipment for post-ripening pellet feed consists of a sealed container with an insulated shell. The interior of the container maintains a certain temperature, and the pellet feed is kept within the container for a certain period of time through indirect or direct heating. Because the pellet feed cannot be stirred during the post-ripening process, the pellet feed overlaps to a certain thickness, resulting in a long processing time, which affects the overall quality of the pellet feed and is also inconvenient for discharging. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a post-ripening equipment for aquatic pellet feed with a reasonable structural design.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] A post-maturation device for aquatic pellet feed includes an insulation box, characterized in that a plurality of belt conveyor mechanisms are connected to the insulation box and the plurality of belt conveyor mechanisms are evenly distributed in the insulation box at different heights. The conveying tail end of the upper belt conveyor mechanism of two adjacent belt conveyor mechanisms is located at the conveying head end of the lower belt conveyor mechanism, and each belt conveyor mechanism includes a conveyor belt with a plurality of through holes; a feed hopper is fixedly connected to the top of the insulation box and above the conveying head end of the uppermost belt conveyor mechanism, and the inner cavity of the feed hopper is connected to the inner cavity of the insulation box; a steam exhaust component is also provided in the insulation box.

[0006] Preferably, the above-mentioned steam exhaust assembly includes multiple groups of steam exhaust pipes, each group of steam exhaust pipes is located below the conveyor belt of each belt conveyor mechanism, and each group of steam exhaust pipes includes a distribution pipe and multiple steam nozzles, wherein one end of the distribution pipe is closed, and the other end passes through the insulation box and is connected to and connected to a main steam output pipe. All distribution pipes share a main steam output pipe, and one end of each steam nozzle is fixedly connected and connected to the distribution pipe, and the other end is closed, and each steam nozzle has a number of steam nozzle holes at the top, and a valve is connected to each distribution pipe.

[0007] Preferably, a blocking piece is fixedly connected to the inner side wall of the heat preservation box corresponding to the conveying head end of each belt transmission mechanism.

[0008] Except for the belt transmission mechanism located at the bottom, the conveying tail end of the belt transmission mechanism of the utility model is a distance away from the corresponding inner wall of the insulation box body, and the conveying tail end of the belt transmission mechanism located at the bottom passes through the insulation box body. The insulation box body is provided with a discharge port for the belt transmission mechanism to output on this side, and a thermal insulation curtain is provided at the discharge port.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The utility model is provided with a belt transmission mechanism and the like, so that the pellet feed to be post-ripened entering the heat preservation box can be spread thinly on the transmission belt and fully contacted with the steam ejected from the steam pipe, thereby improving the post-ripening efficiency. Moreover, due to the transmission of the belt transmission mechanism, the pellet feed does not need to roll by itself, which effectively ensures the integrity of the pellets and improves the quality of the pellet feed.

[0016] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings and preferred embodiments in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. The parts not described in detail below are all carried out according to the existing technology in this field.

[0017] In this article, terms related to connection relationships, such as "fixed connection" and "connection" are all carried out in a conventional manner, such as bolt connection or welding.

[0018] like Figure 1-4 The utility model relates to a post-maturation equipment for aquatic pellet feed, comprising an insulation box 1. The insulation box 1 is a rectangular box made of conventional insulation material. A cleaning window 7 is provided on one side of the insulation box 1 in the width direction, and a cleaning door 8 is hinged at the cleaning window 7 in a conventional manner. A feed hopper 3 is fixedly connected to the top of the insulation box 1 and near the left side. The feed hopper 3 is located above the conveying head end of the uppermost belt transmission mechanism. The cavity inside the feed hopper 3 is connected to the inner cavity of the insulation box 1. When not feeding, the feed hopper 3 is covered with an insulation cover, and the insulation cover is pressed by a weight or bolted to the feed port at the top of the feed hopper 3. An exhaust pipe 9 is fixedly connected to the top of the insulation box 1. An exhaust valve 10 is connected to the exhaust pipe 9 in a conventional manner. The other end of the exhaust pipe 9 can be connected to a conventional bag dust collector.

[0019] Multiple belt conveyors 2 are connected to the insulated box 1 and are evenly distributed at varying heights within the box 1. The tail end of the upper belt conveyor 2 of two adjacent belt conveyors 2 is connected to the head end of the lower belt conveyor 2. Each belt conveyor 2 extends horizontally along the length of the insulated box 1 and comprises a driving roller, a servo motor, a driven roller, and a conveyor belt 2.1. The conveyor belt 2.1 is provided with a plurality of through-holes. The width of the conveyor belt matches the width of the insulated box interior to ensure proper conveyance without dropping pellets. The circular conveyor belt is mounted on a driving and passive roller. The driving and passive shafts, each of which is fixedly connected to the driving and passive rollers, are each rotatably connected to the corresponding side wall of the insulation box 1 via bearings. One end of the driving roller's driving shaft extends from the corresponding side wall (the rear wall) of the insulation box 1 and is fixedly connected to the output shaft of a servo motor. The servo motor drives the conveyor belt in either the forward or reverse direction. A material stopper 11 is fixedly attached to the inner wall of the insulation box 1 corresponding to the head end of each belt conveyor mechanism. This material stopper 11 can be made of hard rubber or silicone. It is positioned at an angle, with a gap between its bottom and the upper surface of the corresponding conveyor belt 2.1. However, this gap is inadequate for pellet feed to pass through.

[0020] A steam exhaust assembly is also provided within the insulated box 1. The steam exhaust assembly includes multiple groups of steam exhaust pipes, each located below each belt conveyor 2. Each group of steam exhaust pipes includes a distribution pipe 4 and multiple steam nozzles 5. One end of the distribution pipe 4 is sealed and fixedly connected to the side wall of the insulated box 1, while the other end extends through the insulated box 1 and connects to a main steam output pipe 6. All distribution pipes 4 share a common main steam output pipe 6, which is sealed at the top and removably connected to a bellows at the bottom. The main steam output pipe is ultimately connected to the steam generator via the bellows in a conventional manner. Each steam nozzle 5 has one end fixedly connected to and connected to the distribution pipe 4 and the other end sealed. Each steam nozzle 5 has a plurality of steam spray holes 5.1 at the top. Each distribution pipe 4 is conventionally connected to a valve, located outside the insulated box 1. The lowest steam exhaust assembly is spaced a distance from the bottom of the insulated box 1.

[0021] Except for the belt conveyor 2 located at the bottom, the conveying tail ends of the other belt conveyor mechanisms 2 of the present invention are some distance away from the corresponding inner wall of the insulation box body 1, and the conveying tail end of the belt conveyor mechanism 2 located at the bottom passes through the insulation box body 1 (the insulation box body 1 is provided with a discharge port for the output of the belt conveyor mechanism 2 on this side), and the discharge port is connected to a thermal insulation electric roller shutter in a conventional manner. When the thermal insulation electric roller shutter is dropped to the maximum position, the bottom of the thermal insulation electric roller shutter contacts the upper surface of the bottom conveyor belt.

[0022] During operation, pellets delivered from the pellet mill fall from the feed hopper 3 onto the top conveyor belt. By controlling the conveyor belt's speed, a layer of pellets is laid flat on conveyor belt 2.1. The conveyor belt is controlled to open only when pellets are present, remaining closed when empty. When pellets are present on any conveyor belt, the valve in the corresponding distribution pipe below opens, spraying steam for post-cooking. When the bottom conveyor belt is completely covered with pellets, the insulated electric roller shutter is opened to a defined opening, allowing only the pellets on the conveyor belt to pass unimpeded.
