Technical Field

[0001] The utility model relates to the technical field of screening devices for shrimp shell grinding, and specifically relates to a multi-stage automatic screening device for shrimp shell grinding. Background Art

[0002] Shrimp shell powder is rich in nutrients such as calcium, protein, and chitin, and can be used as a natural calcium supplement or food additive for baking, soups, seasonings, etc. Processing plants will grind shrimp shells. However, the particles of the shrimp powder after grinding are not the same, so a screening device is needed to screen the shrimp powder and screen out the shrimp powder with larger particles.

[0023] By adding the ground shrimp powder into the storage box 2, covering the cover plate 11, and turning on the first heating strips 14, the first heating strips 14 heat the shrimp powder in the storage box 2. While heating, turn on the driving device 4, and the stirring rack 13 stirs the shrimp powder in the storage box 2 to uniformly heat the shrimp powder in the storage box 2 and ensure the dryness of the shrimp powder. This structural design can improve the screening efficiency of the equipment.

[0024] As Figure 3 - Figure 5 shown, it further includes: a first inclined plate 17 fixedly connected in the feeding box 3; a second inclined plate 18 fixedly connected in the feeding box 3, and the second inclined plate 18 and the first inclined plate 17 are arranged to cooperate to form an S-shaped channel; a plurality of second heating strips 19 all installed on the first inclined plate 17 and the second inclined plate 18.

[0025] Through the structural design of the first inclined plate 17 and the second inclined plate 18, an S-shaped channel is formed in the storage box 2. Turn on the cylinder 10, and the feeding plate 15 slides in the chute of the feeding box 3. Part of the shrimp powder in the storage box 2 falls into the S-shaped channel and flows. Turn on the second heating strips 19 on the first inclined plate 17 and the second inclined plate 18 to perform secondary drying on the shrimp powder. This structural design improves the drying efficiency.

[0026] As Figure 1 - Figure 5As shown in the figure, it further includes: a cylinder 10, installed on the blanking box 3; a blanking plate 15, slidably connected to the groove of the storage box 2, and one end of the blanking plate 15 is fixedly connected to one end of the telescopic rod of the cylinder 10.

[0027] By activating the cylinder 10, the blanking plate 15 is driven to slide in the chute of the blanking box 3, opening the storage box 2, and the shrimp powder in the storage box 2 falls into the screening box 1 for screening.

[0028] As Figure 1 and Figure 2 As shown in the figure, it further includes: a buckle assembly 5, arranged on the storage box 2 and the cover plate 11, so that when the cover plate 11 is received above the storage box 2, the position of the cover plate 11 on the storage box 2 is fixed.

[0029] The buckle assembly 5 includes a snap ring and a hook. When the cover plate 11 is attached to the storage box 2, the snap ring is snapped onto the hook to fix the cover plate 11 on the storage box 2.

[0030] As Figure 1 - Figure 2 As shown in the figure, it further includes: a first screening mechanism 8, arranged in the screening box 1; a first blanking rack 6, fixedly connected to the screening box 1; a second screening mechanism 9, arranged in the screening box 1; a second blanking rack 7, fixedly connected to the screening box 1; a ramp 12, fixedly connected to the bottom inside the screening box 1.

[0031] Through the structural design of the first screening mechanism 8 and the second screening mechanism 9, the shrimp powder is subjected to multi-stage screening, and the first blanking rack 6 and the second blanking rack 7 respectively discharge the shrimp powder screened by the first screening mechanism 8 and the second screening mechanism 9.

[0035] The present utility model provides a multi-stage automatic screening device for shrimp shell grinding, and the specific working principle is as follows:

[0036] When screening the ground shrimp powder, first add the ground shrimp powder into the storage box 2, cover the cover plate 11, and turn on the first heating strip 14. The first heating strip 14 heats the shrimp powder in the storage box 2. While heating, turn on the driving device 4, and the stirring frame 13 stirs the shrimp powder in the storage box 2 to evenly heat the shrimp powder in the storage box 2. After drying is completed, the air cylinder 10 moves the blanking plate 15 in the chute of the blanking box 3, and part of the shrimp powder in the storage box 2 falls into the S-shaped channel to flow. Turn on the second heating strip 19 on the first inclined plate 17 and the second inclined plate 18 to perform secondary drying on the shrimp powder. After the shrimp powder passes through the first inclined plate 17 and the second inclined plate 18, it slides into the screening box 1. The first screening mechanism 8 and the second screening mechanism 9 perform multi-stage screening on the shrimp powder. The shrimp powder screened by the first screening mechanism 8 and the second screening mechanism 9 is discharged from the first blanking rack 6 and the second blanking rack 7 respectively. The finer powder slides out from the slope 12, and thus the screening is completed.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
