Description

Technical Field

[0001] The utility model relates to the technical field of aquatic feed production, in particular to a rapid drying device for aquatic feed production. Background Art

[0002] Aquatic feed is a feed specially provided for aquatic animal breeding. According to the feeding species, aquatic feed can be divided into fish feed, shrimp feed and crab feed; according to the characteristics of the feed, it can be divided into compound feed, concentrated feed and premixed feed. The raw materials for aquatic feed production are mainly composed of fish meal, grain raw materials and oils and fats. Fish meal and grain raw materials often account for more than 50% of the feed cost. In the process of processing aquatic feed, it is necessary to use a drying device to dry the aquatic feed in order to extend the shelf life of the aquatic feed.

[0003] According to a Chinese patent, a drying device for aquatic feed production with publication number CN212133131U realizes the drying operation of aquatic feed through the cooperation of a drying cylinder, a driving motor, a driving shaft, a driving gear, a driven gear, a fan and an electric heating box, and discharges the feed through a discharging hopper and a receiving hopper. However, since the drying cylinder is arranged horizontally, the aquatic feed inside the drying box cannot be completely discharged during the drying process. Therefore, part of the aquatic feed will continue to be dried after drying, resulting in excessive drying of the aquatic feed. In order to avoid excessive drying of the aquatic feed, the usual practice is to manually scrape or discharge the aquatic feed using tools, but this is time-consuming and labor-intensive, and the scraping efficiency is low.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-2 A rapid drying device for aquatic feed production includes a drying box 1 and a drying drum 2. The drying drum 2 is rotatably installed in the drying box 1. In this embodiment, a gear ring is provided on the outer peripheral side of the drying drum 2. A working motor is installed on the drying box 1. The output end of the working motor is connected to a driving gear meshing with the gear ring. When the working motor is working, the gear ring is driven to rotate together with the drying drum 2 through the driving gear. A scraping mechanism 3 extending into the drying drum 2 and used for scraping is provided inside the drying box 1. The scraping mechanism 3 includes a scraper plate 306 movably provided in the drying drum 2 along the axial direction of the drying drum 2. The bottom surface of the scraper plate 306 is close to the bottom wall of the drying drum 2, and is used to scrape the aquatic feed on the bottom wall of the drying drum 2 and push the aquatic feed out of the drying drum 2. In this embodiment, the scraper plate 306 is fan-shaped, and the arc-shaped end edge of the scraper plate 306 is close to the bottom wall of the drying drum 2.

[0027] The scraping mechanism 3 includes a threaded rod 303, a threaded plate 304 and an electric push rod 305. The threaded rod 303 is rotatably arranged in the drying drum 2, and the threaded plate 304 is movably arranged on the threaded rod 303 and is connected to the threaded rod 303 through threads. The electric push rod 305 is installed on the threaded plate 304, and the output end of the electric push rod 305 is connected to the scraping plate 306 downward.

[0028] Preferably, see Figure 1 A limiting rod (not shown) parallel to the threaded rod 303 is provided in the drying cylinder 2, and a limiting hole is provided in the threaded plate 304. The threaded plate 304 is slidably mounted on the limiting rod through the limiting hole. The limiting rod guides the movement of the threaded plate 304 when the threaded plate 304 moves along the length direction of the threaded rod 303, so as to prevent the threaded plate 304 from rotating together with the threaded rod 303.

[0029] See also Figure 1-2 The scraping mechanism 3 further includes a driving motor 301 and a transmission shaft 302. The driving motor 301 is horizontally arranged on the top surface of the drying box 1. The transmission shaft 302 is connected to the output end of the driving motor 301. The transmission shaft 302 is connected to the threaded rod 303 through a belt or a chain. When the driving motor 301 is working, the transmission shaft 302 can be driven to rotate through its output end. The transmission shaft 302 drives the threaded rod 303 to rotate through a belt or a chain, so that the threaded plate 304 moves axially along the threaded rod 303, so as to drive the scraping plate 306 to scrape the material.

When the threaded plate 304 drives the support frame 4 to move, the ball 6 rolls on the inner wall of the drying cylinder 2, thereby reducing the friction between the end of the support frame 4 and the inner wall of the drying cylinder 2, so that the support frame 4 will not affect the rotation of the drying cylinder 2; and the scraper mechanism 3 can be supported by the two support frames 4, which improves the stability of its movement process.

The second baffle 807 adapted to the first baffle 806 is arranged on the inner wall of the feed hopper 7. The first baffle 806 and the second baffle 807 are both perpendicular to the inner wall of the feed hopper 7.

[0032] Preferably, see Figure 5 The first baffle 806 and the second baffle 807 are both semicircular, and are staggered in the feed hopper 7 to cooperate in controlling the feed amount. The first baffle 806 and the second baffle 807 are at a certain angle, and the first baffle 806 can adjust the angle between the first baffle 806 and the second baffle 807 during the rotation process, thereby adjusting the size of the feed opening of the feed hopper 7, thereby achieving control of the feed amount of aquatic feed.

[0033] Preferably, the drying drum 2 has sieve holes for screening aquatic feed, and a receiving hopper is provided at the bottom of the drying drum 2.

[0037] Preferably, the spray plate 905 is an arc-shaped plate structure, and a plurality of spray heads facing the outer wall of the drying cylinder 2 are arranged at equal intervals on its bottom surface.

[0038] The working principle of the utility model is as follows: when in use, the rotating motor 801 is started, and the output end of the rotating motor 801 drives the rotating shaft 802 and the active bevel gear 803 to rotate, and the active bevel gear 803 further drives the driven bevel gear 804, the rotating shaft 805 and the first baffle 806 to rotate together. The first baffle 806 can break up the aquatic feed during the rotation process to prevent the aquatic feed from agglomerating and causing the feed hopper 7 to be blocked. When the first baffle 806 rotates to overlap with the second baffle 807 on the same side, the feed port of the feed hopper 7 is opened to allow the aquatic feed to pass through; when the aquatic feed enters the drying cylinder 2, the electric heating box 901 generates heat, and the fan 902 transmits the heat to the spray plate 905 through the connecting pipe 903, and the aquatic feed is dried through the nozzle on the spray plate 905. In this process , the output end of the working motor drives the driving gear to rotate, and then the gear ring rotates together with the drying drum 2, and the drying drum 2 drives the aquatic feed to roll, so as to achieve uniform drying of the aquatic feed; in this process, the dried aquatic feed can be screened through the sieve holes of the drying drum 2, and the aquatic feed passing through the sieve holes is discharged from the receiving hopper at the bottom; when the aquatic feed is dried to a predetermined time, the driving motor 301 can be started, and the output end of the driving motor 301 drives the transmission shaft 302 and the threaded rod 303 to rotate together under the action of the pulley and the belt, and then the threaded plate 304 moves horizontally along the axial direction of the threaded rod 303, so that the scraping plate 306 under the threaded plate 304 scrapes the material in the drying drum 2 to the discharge hopper, and discharges it from the drying box 1 through the discharge hopper, saving time and labor, thereby improving the scraping efficiency of the aquatic feed.
