[0006] As a preferred embodiment, a rear baffle is fixedly connected between the two pool walls, and the lower end of the rear baffle and the sliding plate forms the discharge port of the cleaning equipment, through which the cleaned and disinfected algae material leaves the cleaning equipment.

[0007] As a preferred embodiment, the inclined plate is parallel to the water receiving plate, the inclined plate has a water spray nozzle and a main feeding port, and the water spray nozzle is connected to one end of the water supply pipe to spray the pressurized disinfectant cleaning solution onto the surface of the algae raw material.

[0008] As a preferred embodiment, the lower surface of the water receiving plate has a drain outlet, which is suitable for connecting to one end of the return pipe to collect the disinfection and cleaning liquid flowing down the conveyor belt into the water storage tank.

[0009] As a preferred embodiment, the low roller is located at the lower end of the conveyor belt, the high roller is located at the upper end of the conveyor belt and above the sliding plate, both the low roller and the high roller are in contact with the inner wall of the conveyor belt, the upper roller is located between the low roller and the high roller and is adapted to contact the inner surface of the conveyor belt, and the lower roller is located below the upper roller and is adapted to contact the outer surface of the conveyor belt, thereby maintaining the tension of the flexible conveyor belt.

[0010] As a preferred embodiment, the outer surface of the conveyor belt also has several equidistant baffles, which are parallel to the axis of the roller shaft, to prevent the algae raw material from sliding down the inclined upper surface of the conveyor belt.

[0011] As a preferred embodiment, the drive mechanism includes a motor and a reducer, with the output end of the reducer connected to the high roller shaft, thereby driving the conveyor belt to work.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a circulation device to continuously supply disinfectant cleaning solution to the cleaning equipment, the algae raw materials are sterilized and disinfected, and the mud and sand adhering to the surface of the algae raw materials are washed away, which effectively improves the safety of algae feed, reduces the mortality rate of shrimp larvae, and increases the aquaculture income.

[0026] like Figure 1-6 The algae feed preparation device for shrimp larvae feeding shown includes a circulating device 1, a washing device 2, and a refining device 3 arranged in a row. The washing device 2 is located between the circulating device 1 and the refining device 3. The washing device 2 includes a pair of parallel vertical tank walls 202. The top of the washing device 2 is open. The two tank walls 202 are rotatably connected to a low roller 203, a high roller 204, an upper roller 205, and a lower roller 206. The axes of the low roller 203, high roller 204, upper roller 205, and lower roller 206 are parallel and together constrain a conveyor belt 207, keeping the conveyor belt 207 inclined. Normally, the high roller 204 is at the same height as the upper roller 205 and is higher than the lower roller 206, while the lower roller 206 is higher than the low roller 203. A drive mechanism 280 is provided on the outer side of the pool wall 202 to drive the rollers to rotate. Specifically, the drive mechanism 280 includes a motor 281 and a reducer 282. The output end of the motor 281 is connected to the input end of the reducer 282, and the output end of the reducer 282 is connected to the high roller 204. The high roller 204 directly drives the conveyor belt 207, and the low roller 203, upper roller 205 and lower roller 206 passively rotate following the conveyor belt 207.

[0027] The low roller 203 is located at the lower end of the conveyor belt 207, and the high roller 204 is located at the upper end of the conveyor belt 207, above the sliding plate 216. Both the low roller 203 and the high roller 204 are in contact with the inner wall of the conveyor belt 207 to tension the flexible conveyor belt 207. The upper roller 205 is located between the low roller 203 and the high roller 204, and is also in contact with the inner surface of the conveyor belt 207. The portion of the conveyor belt 207 between the high roller 204 and the upper roller 205 remains horizontal, while the portion between the upper roller 205 and the low roller 203 remains inclined. The lower roller 20... Located below the upper roller 205, 6 is used to contact the outer surface of the conveyor belt 207. The lower half of the conveyor belt 207 is also constrained into two sections: horizontal and inclined. The conveyor belt 207 has densely distributed through holes to allow water and sediment to pass through, but intact algae raw materials will be intercepted on the upper surface of the conveyor belt 207. The outer surface of the conveyor belt 207 also has several equally spaced baffles. These baffles are all parallel to the axis of the roller and are used to increase the downward sliding of the algae raw materials along the inclined upper surface of the conveyor belt 207. Therefore, the algae raw materials can be carried upward along the inclined direction by the conveyor belt 207 during the washing process.

[0028] Between the two pool walls 202 is a pool bottom 210. The pool bottom 210 is not a plane, but is composed of several non-coplanar flat plates, including a front baffle 211. The upper end of the front baffle 211 has an inclined plate 212 and the lower end has a water receiving plate 215. The water receiving plate 215 is inclined, and its lower end transitions to the upper end of the front baffle 211 by an arc. The upper end of the water receiving plate 215 is connected to a sliding plate 216, which is also inclined and its upper end transitions to the upper end of the water receiving plate 215 by an arc. The water receiving plate 215 is parallel to the inclined part of the conveyor belt 207 with a larger proportion. A rear baffle 209 is also fixedly connected between the two pool walls 202. The rear baffle 209 is parallel to the front baffle 211. The lower end of the rear baffle 209 and the sliding plate 216 form the discharge port of the cleaning equipment 2. The algae raw material, which has been cleaned and has removed mud and other impurities, is discharged from the cleaning equipment 2.

[0029] The circulation device 1 includes a water storage tank 105, which stores not only clean water but also a potassium permanganate solution that can kill harmful microorganisms. A pump body 101 is connected to the top of the water storage tank 105, and a filter 103 is connected to its side. The pump body 101 is used to pump water and supply water to the conveyor belt 207 via a water supply pipe 102. The filter 103 is used to intercept sediment in the potassium permanganate solution after washing. An inclined plate 212 is parallel to a water receiving plate 215, and the inclined plate 212 has spray nozzles 213. It also has a main feeding port 214, in which the spray nozzle 213 is connected to one end of the water supply pipe 102. The pump body 101 pressurizes the potassium permanganate solution and then impacts the algae raw material on the conveyor belt 207 through the spray nozzle 213. The bottom of the pool 210 is connected to the filter 103 through the return pipe 104. The lower surface of the water receiving plate 215 has a drain port 217. The drain port 217 is close to the lower end of the water receiving plate 215 and is used to connect to one end of the return pipe 104 to introduce the cleaned and disinfected potassium permanganate solution into the filter 103.

[0030] The top of the refining device 3 has an inlet 301 and a secondary inlet 302. The inlet 301 is connected to the outlet of the cleaning device 2 and is used to receive the cleaned and disinfected algae raw materials. The secondary inlet 302 is convenient for adding auxiliary materials that do not require cleaning and disinfection, such as rice bran and fish meal. The bottom of the refining device 3 is also equipped with a discharge port 303. In fact, the refining device 3 has two working mechanisms: a crusher and a mixer. The crusher is located below the inlet 301 and is used to crush and refine the algae raw materials entering through the inlet 301. The mixer is located below the discharge port of the crusher and the secondary inlet 302 and is used to mix the crushed algae with auxiliary materials such as rice bran and fish meal. Therefore, the discharge port 303 of the refining device 3 is the discharge port of the mixer.

[0031] Working principle: When in use, the spirulina that has been salvaged is put into the cleaning equipment 2 through the main feeding port 214. The spirulina falls on the upper surface of the inclined part of the conveyor belt 207. The pump body 101 pressurizes the potassium permanganate solution in the water storage tank 105 and sprays it out from the spray nozzle 213 through the water supply pipe 102. On the one hand, it washes the mud and sand on the surface of the spirulina, and on the other hand, it kills the harmful microorganisms that may adhere to the spirulina. The mud and sand will fall into the water receiving plate 215 through the dense opening of the conveyor belt 207 along with the potassium permanganate solution, and enter the filter 103 through the drain port 217 and the return pipe 104. The multi-layer filter screen in the filter 103 intercepts the insoluble matter in the potassium permanganate solution, and the potassium permanganate solution returns to the water storage tank 105.

[0032] After cleaning and disinfection, the spirulina moves upward along the conveyor belt 207 until it falls from the top of the conveyor belt 207 onto the sliding plate 216. Under the limiting action of the rear baffle 209, it enters the feed inlet 301 of the refining device 3 and is crushed into fine particles by the crusher. It then enters the mixer of the refining device 3 and is mixed with an appropriate proportion of auxiliary materials such as rice bran or fish meal through the auxiliary feed inlet 302. This mixture is then fully mixed with the algae to obtain algae feed for shrimp larvae. This feed has higher nutritional value and palatability.
