Description

Technical Field

[0001] This utility model relates to the field of filtration and impurity removal technology, specifically to an impurity removal device for fish slurry feed production. Background Technology

[0002] Fish sol is a byproduct of fish production. It contains a large number of tiny particulate substances 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 components play an irreplaceable role in the nutritional value of carnivorous fish. When applied to feed, it can effectively improve the amount of imported fishmeal added, help users reduce feed input costs, and improve the palatability and absorption rate of animals.

[0003] For example, the national authorized patent announcement number CN223196622U discloses an impurity removal device for fish slurry feed production. The device includes a processing shell, which is hollow with an opening at the top. An inlet is formed on one side of the opening at the top of the processing shell, and an outlet is formed at the bottom. It also includes a partition, a stirring mechanism, a propulsion mechanism, and a filtering mechanism. The partition is located in the middle of the inner wall of the processing shell, dividing the upper and lower sides of the shell into a filtering chamber and a pressure stabilizing chamber. A through hole is formed at the end of the partition away from the inlet. This utility model belongs to the field of filtration and impurity removal technology, specifically a device for filtering fish juice produced after solid-liquid separation from steaming and pressing of marine fish. It disperses the fish juice and internal impurities, causing them to float. After passing through multiple layers of filter screens, the filtered fish juice flows rapidly and is stabilized in the pressure stabilizing chamber. This device is used for impurity removal in fish slurry feed production.

[0004] However, the aforementioned impurity removal equipment for fish slurry feed production relies on multi-layer static filtration and only uses a stirring mechanism to float impurities. It does not classify and intercept the characteristics of fish slurry where "large impurities (such as broken fish bones and fish skin) are mixed with small impurities (such as fine sand and tiny fish tendons)". Large impurities tend to accumulate on the surface of the first layer of filter screen and clog the filter screen pores in a short time, which increases the flow resistance of fish slurry. This not only requires frequent shutdowns to clean the filter screen, but also significantly reduces the filtration capacity per unit time, making it difficult to meet the continuous production needs of large-scale fish slurry feed. Utility Model Content

[0005] The purpose of this invention is to provide an impurity removal device for fish slurry feed production, in order to solve the problems mentioned in the background art, such as easy clogging of multi-layer static filters, high resistance to fish slurry flow, need for frequent shutdowns to clean the filters, low filtration capacity per unit time, and difficulty in adapting to large-scale continuous production of fish slurry feed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A device for removing impurities in fish slurry feed production includes: a support frame, with rollers rotatably mounted on the upper surfaces of the four corners of the support frame, and collars rolling on the outer surfaces of the four sets of rollers, with a fish slurry feed raw material impurity removal mechanism elastically connected inside the collars.

[0007] Preferably, one set of the rollers is fixedly connected to the output shaft of the geared motor, and the geared motor is fixedly mounted at one end of the support frame.

[0008] Preferably, the impurity removal mechanism for fish slurry feed production raw materials includes multiple sets of springs. The springs are distributed in an equidistant ring shape and are symmetrically fixed on both sides of the inner ring wall of the collar. The other ends of the springs on both sides of the collar are fixedly connected to the outer surface of the filter cartridge, so that the filter cartridge is suspended and assembled inside the collar.

[0009] Preferably, the two ends of the filter cartridge extend from the two ends of the collar, and a vibration motor is fixedly installed on the upper and lower ends of the outer surface of the filter cartridge extending from the two ends of the collar.

[0010] Preferably, a spiral blade is fixedly installed on the inner ring surface of the filter cartridge, and filter holes are formed in the pitch area of ​​the spiral blade.

[0011] Preferably, the diameter of the filter holes in the pitch of the spiral blade is set from large to small along the length extension direction of the spiral blade.

[0012] Preferably, the lower ends of the outer surfaces of the filter cylinder and the collar are arranged perpendicularly to the first collection hopper, and the first collection hopper is connected and installed on the lower surface of the support frame.

[0013] Preferably, a second collection hopper is provided at the lower end of the spiral blade inside the filter cartridge, and the second collection hopper is fixedly installed at one end of the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The filter cartridge is stably rotated by a roller driven by a geared motor, and the filter cartridge is suspended by a spring. This not only buffers the rigid impact during rotation and reduces component wear and operating noise, but also prevents the accumulation of fish slurry by the high-frequency vibration of the vibrating motor. At the same time, the pushing action of the spiral blades and the graded filter hole design achieve precise interception and separation of large and small impurities. Qualified fish slurry and impurities are collected independently through corresponding collection hoppers, effectively avoiding filter hole clogging and eliminating the need for frequent shutdowns for cleaning. This greatly improves filtration efficiency and fish slurry purity, meeting the needs of large-scale, continuous fish slurry feed production. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 The present invention provides the following technical solution: like Figure 1 As shown, a fish slurry feed production impurity removal device includes: a support frame 1, with rollers 103 rotatably mounted on the upper surfaces of the four corners of the support frame 1. A collar 105 rolls on the outer surface of the four sets of rollers 103, and a fish slurry feed raw material impurity removal mechanism 2 is elastically connected inside the collar 105. One set of rollers 103 is fixedly connected to the output shaft of a reduction motor 104, which is fixedly mounted at one end of the support frame 1.

[0019] Through the design of the support frame 1, the first hopper 101, the second hopper 102, the rollers 103, the reduction motor 104, the collar 105, and the fish slurry feed raw material impurity removal mechanism 2, when the equipment is started, the reduction motor 104 fixed at one end of the support frame 1 starts to run. Its output shaft drives one of the sets of rollers 103 fixedly connected to it to rotate. Since all four sets of rollers 103 are rotatably mounted on the four corners of the support frame 1, and the collar 105 rolls and supports the outer surfaces of the four sets of rollers 103, the collar 105 will rotate stably under the support and drive of the four sets of rollers 103 as the set of rollers 103 rotates. Furthermore, because the fish slurry feed raw material impurity removal mechanism 2 is elastically connected inside the collar 105, the rotation of the collar 105 will synchronously drive the fish slurry feed... The raw material impurity removal mechanism 2 rotates, at which time the fish slurry to be filtered is transported into the fish slurry feed raw material impurity removal mechanism 2. The rotating fish slurry feed raw material impurity removal mechanism 2 will filter the fish slurry. During the filtration process, impurities in the fish slurry will be intercepted by the fish slurry feed raw material impurity removal mechanism 2, while qualified fish slurry will pass through the fish slurry feed raw material impurity removal mechanism 2 and the collar 105 and be discharged from the first collection hopper 101 for collection. The second collection hopper 102 in the filter cylinder 202 can collect the impurities intercepted by the fish slurry feed raw material impurity removal mechanism 2, realizing efficient separation of fish slurry and impurities. There is no need for frequent shutdowns for cleaning, which effectively improves the efficiency and continuity of fish slurry filtration and meets the needs of large-scale production.

[0020] like Figures 2-3 As shown, the impurity removal mechanism 2 for fish slurry feed production includes multiple sets of springs 201. The springs 201 are distributed in an equidistant ring and are symmetrically fixed on both sides of the inner ring wall of the collar 105. The other ends of the springs 201 on both sides of the collar 105 are fixedly connected to the outer surface of the filter cylinder 202, so that the filter cylinder 202 is suspended and assembled inside the collar 105. The two ends of the filter cylinder 202 extend from the two ends of the collar 105, and the upper and lower ends of the outer surface of the filter cylinder 202 extending from the two ends of the collar 105 are fixedly installed with vibration motors 204. A spiral blade 203 is fixedly installed on the inner ring surface of the filter cylinder 202, and filter holes are opened in the pitch area of ​​the spiral blade 203. The diameter of the filter holes in the pitch of the spiral blade 203 is set from large to small along the length extension direction of the spiral blade 203. The lower ends of the outer surfaces of the filter cartridge 202 and the collar 105 are perpendicularly opposite to the first collecting hopper 101, which is connected to the lower surface of the support frame 1. The lower end of the spiral blade 203 inside the filter cartridge 202 is correspondingly provided with a second collecting hopper 102, which is fixedly installed at one end of the support frame 1.

[0021] Through the design of springs 201, filter cartridge 202, spiral blades 203, and vibration motor 204, when the reduction motor 104 drives the corresponding rollers 103 to make the collar 105 rotate stably under the support of four sets of rollers 103, the springs 201, which are equidistantly distributed in a ring shape on both sides of the inner ring wall of the collar 105, will synchronously drive the filter cartridge 202, which is fixedly connected to it, to rotate. The filter cartridge 202 achieves a suspended assembly through the springs 201, which can buffer the rigid impact between the filter cartridge 202 and the collar 105 during rotation, reduce component wear, and reduce operating noise. At the same time, the vibration motor 204, which is fixed to the part of the filter cartridge 202 that extends out of the collar 105, starts, causing the filter cartridge 202 to generate high-frequency slight vibration, preventing the fish slurry from accumulating on the inner wall of the filter cartridge 202 and the surface of the spiral blades 203. At this time, the fish slurry to be filtered is transported into the filter cartridge 202. The rotation of the filter cartridge 202 drives the spiral blades 203 on the inner ring surface to rotate synchronously. While the fish slurry is pushed along the length of the filter cylinder 202, the filter holes in its pitch area, with their diameter decreasing along the length, first intercept large-volume impurities in the fish slurry, such as broken fish bones and fish skin, and then filter out small particulate impurities, such as fine sand and tiny fish tendons, achieving graded filtration. The qualified fish slurry, after passing through the filter holes, can be collected from the first collection hopper 101, which is perpendicular to the lower end of the outer surface of the filter cylinder 202 and the collar 105. The intercepted impurities, pushed by the spiral blade 203, eventually fall into the second collection hopper 102, which is corresponding to the lower end of the spiral blade 203 inside the filter cylinder 202. Throughout the process, the suspension support of the spring 201 improves the vibration transmission efficiency of the filter cylinder 202. The vibration of the vibration motor 204, combined with the pushing of the spiral blade 203 and the graded filter holes, effectively avoids filter hole clogging, greatly improves filtration efficiency and fish slurry purity, and eliminates the need for frequent shutdowns for cleaning, meeting the needs of large-scale production.

[0022] Based on the above technical solution, the working steps of this solution are summarized as follows: When the equipment starts, the reduction motor 104 fixed at one end of the support frame 1 starts to run. Its output shaft drives one of the sets of rollers 103 fixedly connected to it to rotate. Since all four sets of rollers 103 are rotatably mounted on the upper surfaces of the four corners of the support frame 1, and the collar 105 rolls and supports the outer surfaces of the four sets of rollers 103, the collar 105 will rotate stably under the support and drive of the four sets of rollers 103 as the set of rollers 103 rotates. The collar 105 will synchronously drive the filter cartridge 202 fixedly connected to it to rotate through the springs 201 distributed at equal intervals on both sides of the inner ring wall. The filter cartridge 202 achieves a suspended assembly through the springs 201. At the same time, the vibration motor 204 fixed to the part of the filter cartridge 202 extending out of the collar 105 at both ends starts, driving the filter cartridge 202 to produce The filter cartridge 202 generates a high-frequency, slight vibration to prevent the fish slurry from accumulating on the inner wall of the filter cartridge 202 and the surface of the spiral blade 203. At this time, the fish slurry to be filtered is transported into the filter cartridge 202. The rotation of the filter cartridge 202 drives the spiral blade 203 on the inner ring surface to rotate synchronously. While the spiral blade 203 pushes the fish slurry along the length of the filter cartridge 202, the filter holes in its pitch area, with the aperture decreasing from large to small along the length extension direction, will first intercept large-volume impurities in the fish slurry, such as broken fish bones and fish skin, and then filter small particulate impurities, such as fine sand and tiny fish tendons, to achieve graded filtration. After passing through the filter holes, the qualified fish slurry can be collected from the first collection hopper 101, which is perpendicular to the lower end of the outer surface of the filter cartridge 202 and the collar 105. The intercepted impurities are pushed by the spiral blade 203 and finally fall into the second collection hopper 102 corresponding to the lower end of the spiral blade 203 inside the filter cartridge 202.

[0023] In summary: The suspension support of spring 201 improves the vibration transmission efficiency of filter cartridge 202. The vibration of vibration motor 204, combined with the pushing of spiral blade 203 and the grading filter holes, effectively avoids filter hole clogging, significantly improves filtration efficiency and fish slurry purity, and eliminates the need for frequent shutdowns for cleaning, meeting the needs of large-scale production.
