Technical Field

[0001] The utility model relates to the technical field of fish product production and processing equipment, in particular to a small fish air separation and impurity removal structure which is convenient to adjust and has strong applicability. Background Technique

[0002] In the existing processing of fish products, there is a type of small fish dried product. In the early stage of its processing steps, pre-cleaning is included. After pre-cleaning, the small fish enter the discharge port at the end of the primary cleaning and conveying equipment, and fall onto the guiding plate through the discharge port, slide down along the guiding plate to the conveyor belt, and enter the next processing step. However, certain impurities and pollutants may still remain in the fresh small fish during the pre-cleaning process. Considering factors such as reducing the subsequent processing pressure and improving the product quality, it is necessary to remove the remaining impurities and pollutants before entering the next processing step.

[0003] The existing removal process has the following problems:

[0004] 1. There is an urgent need for a device to remove impurities and pollutants during the falling process of fresh small fish;

[0005] 2. Most of the existing removal devices are fixedly configured, and it is difficult to synchronously adjust according to different types of small fish or problems that occur in the actual production situation, resulting in poor applicability. Content of the Utility Model

The air blown out by the air separation and impurity removal mechanism 4 passes between the discharge port 1 and the material guiding plate 2 and then points to the recycling mechanism 5.

[0030] With the air separation and impurity removal mechanism 4 of the present utility model, when fresh small fish fall, the sundries and pollutants are blown out by using the fact that their weights are lighter than those of the small fish, and are collected by the recycling mechanism 5, reducing the subsequent processing pressure and improving the product quality; secondly, the air separation and impurity removal mechanism 4 is easy to adjust, facilitating adjustment according to the actual situation and increasing the applicability.

[0031] As a preferred Embodiment 2, the air separation and impurity removal mechanism 4 includes oppositely arranged mounting frames 401, and the mounting frames 401 are both vertically arranged. A plurality of air curtain machines 404 are detachably provided between the mounting frames 401 through installation parts 402 and fastening bolts 403.

[0032] One side of the air curtain machine 404 near the air outlet points to the recycling mechanism 5 after passing through the material outlet 1 and between the material guiding plates 2. Mounting members 402 are provided at the four corners on the side of the air curtain machine 404 far from the air outlet, and the mounting members 402 are symmetrically arranged in pairs with respect to the middle position of the air curtain machine 404. The mounting members 402 located in the same vertical direction are slidably mounted on the same corresponding mounting frame 401, and the mounting members 402 are detachably fixedly coupled to the mounting frame 401 through fastening bolts 403.

[0033] A limiting groove 4021 is provided on the mounting member 402, and the limiting groove 4021 and the mounting member 402 cooperate to form a "U"-shaped structure. The corresponding mounting frame 401 is movably embedded in the limiting groove 4021 along the vertical direction. Limiting holes 4022 are provided on both sides of the limiting groove 4021 of the mounting member 402, and the limiting holes 4022 are symmetrically arranged with respect to the limiting groove 4021. A strip-shaped hole 4011 extending in the vertical direction is provided on the mounting frame 401, and the limiting hole 4022 always coincides with the strip-shaped hole 4011. The screw rod of the fastening bolt 403 passes through the limiting hole 4022 and the strip-shaped hole 4011 at the same time. Nuts are threadedly engaged at both ends of the screw rod, and the two sides of the mounting member 402 are fixedly coupled to the mounting frame 401 through the nuts of the fastening bolts 403 to form a pressing and fixing fit.

[0039] Reinforcing rib frames 503 are provided at the bottom of the side of the recycling box 501 far from the conveyor belt 3 to prevent the recycling mechanism 5 from tipping over due to the baffle 502 bearing wind force during the air separation process.

[0041] The utility model uses the air separation and impurity removal mechanism 4. When fresh small fish fall, since the weight of sundries and pollutants is lighter than that of the small fish, the sundries and pollutants are blown out and collected by the recycling mechanism 5, reducing the subsequent processing pressure and improving the product quality;

[0042] Secondly, the air curtain machine 404 of the air separation and impurity removal mechanism 4 is convenient to adjust through the mounting member 402 and the fastening bolt 403, facilitating adjustment according to the actual situation and increasing applicability.
