Description

Technical Field

[0001] The present application relates to the technical field of fish processing, and in particular to a descaling machine. Background Art

[0002] Descaling machine is a kind of equipment widely used for processing scales on the surface of fish. There are many types of descaling machines on the market, including rotary brush type, scraper type and spray washing type.

[0003] The rotating brush type mainly uses a high-speed rotating nylon brush. When in use, the fish is pressed against the nylon rotating brush and pushed in the opposite direction of its rotation, using friction to remove the fish scales one by one. The scraper type mainly uses a rotating metal scraper to remove the fish scales. Both methods come into contact with the fish's surface, and the process of removing the fish scales may cause damage to the fish's surface. The spray-washing type uses a high-pressure water gun to rinse the fish's surface, thereby flushing off the fish scales and ensuring the integrity of the fish's epidermis.

[0004] Generally, a spray-washing descaling machine includes a frame, a first conveyor mesh belt for conveying fish, a second conveyor mesh belt arranged above the conveyor mesh belt for pressing against the fish, and a high-pressure nozzle for removing scales on the surface of the fish. The high-pressure nozzles are generally arranged on the upper and lower sides of the first conveyor mesh belt, and multiple nozzles can be arranged along the direction of the first conveyor mesh belt; the frame as a whole is a closed structure, and a discharge port is arranged at the bottom of the frame for delivering a mixture of fish scales and wastewater.

[0005] With regard to the above-mentioned related technologies, the method of directly discharging the mixture of fish scales and wastewater in the spray-washing descaling machine not only generates a large amount of wastewater that needs to be treated, but also has a low utilization rate of water resources.

[0044] The implementation principle of a fish scaler in an embodiment of this application is as follows: When using the fish scaler, the fish scales are removed by the impact of a high-pressure water gun and enter the water collection frame 2 together with the wastewater; under the guidance of the water guide plate 21, the mixture of fish scales and wastewater falls on the middle part of the filter mesh belt 3. As the filter mesh belt 3 rotates, the wastewater falls through the filter holes to the lower end of the water collection frame 2, and then is sent out by the water outlet pipe 6 after passing through the filter cylinder 9 again and flows back into the high-pressure water gun for recycling; while the fish scales are left on the filter mesh belt 3 and fall into the aggregate frame 5 under the action of gravity as the filter mesh belt 3 turns up and down, and when the filter mesh belt 3 rotates to the position of the scraping plate 7, the scraping plate 7 scrapes the fish scales into the aggregate frame 5 for collection.

[0045] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
