Description

Technical Field

[0001] The utility model belongs to the technical field of filtering and removing impurities, in particular to an impurity removal device for producing fish slurry feed. Background Art

[0002] Fish slurry is a byproduct of the fish meal production process. It contains a large amount of tiny particulate matter suspended in water, such as dissolved proteins, peptides, and amino acids. It also contains biogenic amines, trimethylamine oxide, and small amounts of oil and trace elements. These bioactive ingredients have an irreplaceable role in the nutritional value of carnivorous fish. Its application in feed effectively increases the amount of imported fish meal added, helping users reduce feed input costs and improve animal palatability and absorption.

[0003] After the fish is steamed and pressed to separate, solid matter and fish juice are formed. The fish juice is enzymatically hydrolyzed and concentrated to produce fish slurry. At the same time, the fish juice is defatted to produce fish oil. Before the fish juice is processed, the fish juice contains impurities, which affect the fish slurry generated by enzymatic hydrolysis and concentration, and thus affect the quality of the subsequent fish slurry powder. Utility Model Content

[0004] The technical problem to be solved by the utility model is that before the fish juice is processed, the fish juice contains impurities, which have an impact on the quality of the subsequent production of fish soluble slurry and fish soluble slurry powder.

[0006] The stirring mechanism is arranged at one end of the processing shell near the feed port, and is used to stir and disperse impurities in the fish juice. The propulsion mechanism is arranged at one end of the processing shell away from the feed port. The propulsion mechanism is connected to the filter chamber and the pressure stabilizing chamber through the through hole respectively, and is used to transport the fish juice and increase the flow rate. The filtering mechanism is inserted in the middle of the filter chamber and is used to filter impurities in the fish juice.

[0007] Furthermore, the stirring mechanism includes a motor 1, a rotating shaft and a stirring rod. The rotating shaft can be rotatably arranged between the opposite inner walls of the processing shell near one end of the feed port. The stirring rod is fixedly connected to the outer wall of the rotating shaft. The stirring rod is U-shaped and arranged in a ring-shaped and evenly spaced manner. The motor 1 is installed on the outer wall of the processing shell, and the output end of the motor 1 is fixedly connected to one end of the rotating shaft.

[0008] Furthermore, the propulsion mechanism includes a supporting plate, motor 2 and an auger, the supporting plate is arranged at the upper part of the processing shell away from the feed port, the supporting plate is located at the upper part of the through hole, the motor 2 is arranged at the center of the upper part of the supporting plate, and the auger passes through the through hole and is fixedly connected to the telescopic end of motor 2.

[0009] Furthermore, the filtering mechanism includes an insert plate and a filter screen, the insert plate is arranged in an inverted L shape, the insert plate is upside down on the upper wall of the processing shell along the inner wall relative to the processing shell, the insert plates are arranged symmetrically, and the filter screen is arranged between the symmetrical insert plates, the filter screens are arranged at equal intervals, and the filter screens arranged at equal intervals are arranged at an angle.

[0013] After adopting the above structure, the beneficial effects of the utility model are as follows: the fish juice produced by the solid-liquid separation after steaming and squeezing of marine fish is filtered, and the produced fish juice is carried by the processing shell. After feeding, the fish juice and internal impurities are broken up by the stirring mechanism to make them float, filtered through multiple layers of filter screens, and enter the bottom of the partition through the through hole. When passing through the through hole, the propulsion mechanism pushes the filtered fish juice to flow quickly, increasing the flow rate.

DETAILED DESCRIPTION

[0020] like Figure 1-4 As shown, an impurity removal device for fish slurry feed production includes a processing shell 1, which is hollow with an upper opening. A feed inlet 2 is formed on one side of the upper opening of the processing shell 1, and a discharge port 3 is formed at the bottom of the processing shell 1. The processing shell 1 also includes a partition 4, a stirring mechanism 5, a propulsion mechanism 6 and a filtering mechanism 7. The partition 4 is provided in the middle of the inner side wall of the processing shell 1 to separate the upper and lower sides of the processing shell 1 into a filtering chamber 8 and a pressure stabilizing chamber 9. A through hole 24 is formed on the end of the partition 4 away from the feed inlet 2.

[0021] The stirring mechanism 5 is arranged at one end of the processing shell 1 near the feed port 2, and is used to stir and disperse impurities in the fish juice. The propulsion mechanism 6 is arranged at the end of the processing shell 1 away from the feed port 2. The propulsion mechanism 6 passes through the through hole 24 and is respectively connected to the filter chamber 8 and the pressure stabilizing chamber 9, and is used to transport the fish juice and increase the flow rate. The filtering mechanism 7 is inserted in the middle of the filter chamber 8 to filter impurities in the fish juice.

[0022] like Figure 3 and Figure 4 As shown, in order to achieve uniform distribution of impurities in the fish juice after feeding and improve the filtering effect, the stirring mechanism 5 includes a motor 10, a rotating shaft 11 and a stirring rod 12. The rotating shaft 11 is rotatably arranged between the opposite inner walls of the processing shell 1 near one end of the feed port 2, and the stirring rod 12 is fixedly connected to the outer wall of the rotating shaft 11. The stirring rod 12 is U-shaped and arranged in a ring-shaped and evenly spaced manner. The motor 10 is installed on the outer wall of the processing shell 1, and the output end of the motor 10 is fixedly connected to one end of the rotating shaft 11. The motor 10 drives the rotating shaft 11 to rotate, so that the stirring rods 12 arranged in a ring-shaped and evenly spaced manner stir the fish juice, so that the impurities in the fish juice are evenly distributed, and the impurities are prevented from being deposited on the partition 4 after the fish juice is fed.

[0023] like Figure 3 and Figure 4As shown, in order to increase the flow rate of the fish juice in the processing shell 1 and improve the filtration efficiency, the propulsion mechanism 6 includes a supporting plate 13, a second motor 14 and an auger 15. The supporting plate 13 is arranged at the upper part of the processing shell 1 away from the end of the feed port 2, the supporting plate 13 is located on the upper part of the through hole 24, the second motor 14 is arranged at the center of the upper part of the supporting plate 13, the auger 15 passes through the through hole 24 and is fixedly connected to the telescopic end of the second motor 14, the second motor 14 drives the auger 15 to rotate in the through hole 24, and the filtered fish juice is pushed by the auger 15 to increase the flow rate of the fish juice and enter the pressure stabilizing chamber 9. The upper wall and bottom wall of the pressure stabilizing chamber 9 close to the through hole 24 are respectively provided with blocks 21 for pressurizing the fish juice discharged from the through hole 24. The pressure of the fish juice increases when passing through the symmetrical blocks 21, so that the fish juice in the pressure stabilizing chamber 9 flows rapidly, increasing the flow of fish juice in the upper filter chamber 8.

[0024] like Figure 3 and Figure 4 As shown, in order to improve the filtering effect and facilitate cleaning and maintenance of the filtering mechanism 7, the filtering mechanism 7 includes an insert plate 16 and a filter screen 17. The insert plate 16 is arranged in an inverted L shape. The insert plate 16 is upside down on the upper wall of the processing shell 1 along the inner wall relative to the processing shell 1. The insert plates 16 are symmetrically arranged, and the filter screen 17 is arranged between the symmetrical insert plates 16. The filter screens 17 are arranged at equal intervals. The filter screens 17 arranged at equal intervals are inclined. After the impurities evenly distributed in the fish juice are broken up, they flow toward the through hole 24. After being filtered by multiple layers of filter screens 17, they enter the through hole 24. The filter screens 17 are evenly distributed, which limits the filtering area of each layer of filter screen 17. This avoids blockage caused by concentrated filtration of impurities, and makes the impurities evenly distributed and filtered, thereby improving the filtering effect.

[0025] Among them, the discharge port 3 is connected to a discharge barrel 18, and a slot 19 is opened on the inner wall of the discharge barrel 18. A filter screen plate 20 is clamped in the slot 19 to filter the fish juice again before discharging it, thereby reducing the discharge pressure of the discharge port 3 and avoiding the spraying of fish juice. A support leg 22 is provided in the middle of the bottom of the processing shell 1, and a support rod 23 is fixedly connected to the bottom of the support leg 22 to increase the height of the processing shell 1 and increase the stability of the device.

[0026] When in use, the operator places the device in a fixed position, receives the fish juice through the feed port 2, and after the fish juice enters the filter chamber 8 above the partition 4, the operator drives the motor 10 to rotate, and the motor 10 drives the rotating shaft 11 to rotate, so that the stirring rods 12 arranged in an annular manner with equal spacing stir the fish juice, so that the impurities in the fish juice are evenly distributed, and the impurities are prevented from being deposited on the partition 4 after the fish juice is fed;

[0027] The fish juice passes through the filter 17, which limits the filtering area of each layer of the filter 17, avoiding blockage caused by concentrated filtration of impurities, and makes the impurities evenly distributed and filtered, thereby improving the filtering effect. The filtered fish juice enters the through hole 24, driving the second motor 14 to rotate, promoting the flow of the fish juice in the through hole 24, and increasing the flow rate of the fish juice;

[0028] When the fish juice passes through the symmetrical block 21, its pressure is increased, causing the fish juice in the filter chamber 8 to flow quickly. After flowing through the pressure stabilizing chamber 9 for a distance, the pressure of the fish juice is stabilized and the fish juice is discharged from the discharge barrel 18. During the discharge, the fish juice is filtered again to reduce the discharge pressure of the discharge port 3.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
