[0035] A sealing shield is provided at the upper opening of the tank body, and the mesh chain conveyor turns into a plane conveying section II after the shield is extended from the front end of the tank body; a feed port 3 is provided on the sealing shield, and the krill raw materials to be cleaned enter the tank body 1 from the feed port 3 and fall onto the plane conveying section I; an observation window 4 is also provided on the sealing shield 2. Preferably, the inclination of the front end side of the tank body is consistent with the inclination angle of the climbing conveying section (the angle between the climbing conveying section and the placement plane). This design can save space in the tank body. Without affecting the climbing conveying, a bubble machine 14, a circulating water pump 9, a fresh water pump 13, pipelines, etc. can be placed below the front section of the tank body, which can save the overall space occupied by the equipment.

[0036] The fresh water in the tank is continuously replenished in a low-in and high-out manner. The specific design is as follows: three overflow ports (DN100 stainless steel float valves) are installed on the side of the rear end of the tank at a position higher than the plane conveying section I. The three overflow ports 11 are installed at three heights: high, medium and low. The water level in the tank is determined according to the amount of krill raw materials, and the overflow ports of corresponding heights are selected and switched. A drain port 10 is also provided at the bottom of the tank. When the salt content of the fresh water in the tank exceeds the standard, it is completely discharged through the drain port 10, and new fresh water is added to the tank through the fresh water tank 8 connected to the drain port 10.

The bubble air supply pump (bubble fan) is connected to a bubble tube 16 through an air supply pipe 15. The bubble tube 16 is located between the upper and lower screens of the plane conveying section I. A pipeline with a circulating water nozzle 17 is provided above the plane conveying section I. The circulating water pump 9 pumps the fresh water in the tank into the circulating water nozzle 17 through the pipeline and sprays it to the krill on the plane conveying section I. At the same time, the bubble tube 16 injects uniform bubbles upward, so that the raw krill is washed by fresh water in the plane conveying section I and dispersed by bubbles at the same time, so that the krill is fully and evenly washed in the fresh water.

[0038] The secondary spraying system comprises a fresh water tank 8, a fresh water pump 13, a spray pipe 18 and a plurality of nozzles arranged on the spray pipe, wherein the plurality of nozzles are located above the climbing conveying section, and the spray pipe above the climbing conveying section has the same inclination angle as the climbing conveying section; the fresh water in the fresh water storage tank 8 is transmitted to the spray pipe 18 through the fresh water pump and sprayed to the krill on the climbing conveying section through the nozzles thereon for secondary washing; during the filtering and washing process, the washed water seeps down along the mesh belt into the drainage recovery chute 7 and slides down and is recovered into the tank body 1.

The krill filtered and washed by the secondary spray system are transported to the wind-blown drainage system, the fan installed above the krill blows air downward, and the mesh belt under the krill drains water downward, fully draining the water on the surface of the krill to achieve the minimum salt content.

[0040] The bubble salt washing machine also includes a metal detection system. After the krill treated by the wind-blowing and drainage system is discharged from the discharge port, it is conveyed by a mesh belt to the metal detection system to detect whether it contains metal substances, and the section containing metal substances is removed. The krill is transported by the conveyor belt (food-grade plastic chain plate) of the metal detection system and then inspected to the original shrimp tank. During the process, if the krill is detected to contain metal substances, the section containing metal will be removed, so that the raw materials will not contain metal, which increases the quality of krill products and reduces the damage rate of downstream equipment.

[0041] Preferably, the metal detection system includes a metal detector, a food-grade plastic chain plate and a pneumatic automatic flap. When the metal detector detects unqualified products on the food-grade plastic chain plate, the unqualified products are removed by a pneumatic automatic flap.

[0042] Embodiment 1:

[0043] The bubble salt washing machine of this embodiment has an overall length of 8000mm and a width of 1020mm; the water tank section (tank body) is 1220mm high and 4046mm long; the air shower and drain section is 3954mm long and 1700mm high; and it is made of all food-grade 304 and 316 stainless steel.

[0044] When using, first clean the tank, fill it with water, and inject water until the overflow port overflows; start the conveyor belt motor to make the belt run normally and in the correct direction; start the vortex pump (bubble machine) to inject air into the water in the tank to generate bubbles, so that the water in the tank churns; open the spray pipe valve to spray water evenly on the belt; check all running parts, and start cleaning after they run correctly and normally. The cleaning process is as follows:

[0045] Fresh raw krill is transported by conveyor to the water tank of the equipment, washed by fresh water in the water tank and dispersed by uniform bubbles at the same time. Because the krill is not loose and very uneven when it just comes down, the bubble machine plays a key role at this time, breaking up the krill to achieve full and uniform washing in fresh water.

[0046] The fresh water in the tank is replenished continuously in a low-in and high-out manner, with a water consumption of about 1.2t / h; the fresh water in the fresh water tank is pumped into the tank by a primary water supply pump (the primary water supply pump supplies pressurized fresh water to the engine room), and a float automatic water cut-off device is provided on the top of the fresh water tank (the fresh water tank controls the water supply solenoid valve through a float switch). When the water is full, water will be automatically added, and when the water is insufficient, water will be automatically added. The water tank stores about 100L of water. Clean fresh water is pumped into the shrimp washing tank, and the high-position overflow valve overflows the excess sewage.

[0047] The krill treated by the bubble water washing system is conveyed by a mesh belt conveyor to the secondary spraying system, in which clean fresh water is sprayed onto the washed krill again to achieve secondary filtration and washing; during the washing process, the washed water seeps down along the mesh belt and is recovered into the tank along the chute.

[0048] The krill after secondary cleaning is transported to the wind-blowing and drainage system, where the fan 5 with the screen 20 blows air downward, and the screen belt below drains water downward, fully draining the water on the surface of the krill to achieve the minimum salt content.

[0049] After being blown and drained, the krill are transported by the mesh belt to the metal detector end, and then transported by the conveyor belt of the metal detector to the original shrimp buffer tank after being inspected by the metal detector. During this period, if metal substances are detected in the krill, the detector will provide a signal to the rejection system, and the rejection system will open the flap to reject the metal-containing material outside the equipment.

[0050] The fresh water consumption of the foam salt washer of the utility model is about 1.2 t / h; the salt content of the krill before cleaning is more than 4%, and the salt content after cleaning is reduced to less than 2%.
