Description

Technical Field

[0001] This utility model belongs to the field of fish oil processing technology, and in particular relates to a filtration device for fish oil processing. Background Technology

[0002] In the production and processing of fish oil, in order to improve product quality, it is often necessary to use filtration devices to remove impurities from the fish oil.

[0003] Chinese utility model patent CN222738635U discloses a filtration device for fish oil production. A second motor drives a brush roller to rotate, and a drive mechanism moves a movable frame, allowing the brush roller on the movable frame to clean the filter plate. Brush rollers with a large amount of filter material adhering to them can be moved outside the device for cleaning, thus cleaning the filter plate without disassembling the filter assembly, which is highly efficient and convenient. However, in actual use, this device has drawbacks, including difficulty in quickly discharging filtered impurities and inconvenient cleaning. Furthermore, since some impurities are hygroscopic, direct discharge can lead to waste of fish oil.

[0004] Therefore, there is an urgent need to improve existing filtration devices for fish oil processing and provide a filtration device for fish oil processing that can quickly remove impurities. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a fish oil processing filter device that is reasonably designed, simple in structure, quick in removing impurities, and has dehydration and waste prevention functions, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A filtration device for fish oil processing includes a filter box, a filter screen plate fixedly installed on the inner side of the upper end of the filter box, a drive assembly located at the front left of the top of the filter box, a scraper located on the upper left of the filter screen plate, the scraper being driven by the drive assembly to move left and right, a slag discharge assembly located on the upper right of the filter screen plate, an electric push rod fixedly installed on the outer right side of the filter box, a movable plate fixedly connected to the telescopic end of the electric push rod, a first guide groove being formed inside one end of the movable plate, a second guide groove being formed inside the other end of the movable plate, the first guide groove and the second guide groove being respectively connected to the slag discharge assembly, a slag discharge port being formed at the rear right of the top of the filter box, the bottom end face of the slag discharge port being flush with the upper surface of the filter screen plate, and a discharge port being formed at the bottom of the filter box.

[0008] Preferably, the lower half of the filter box has a funnel-shaped structure, and the discharge port is located at the bottom of the funnel-shaped structure.

[0009] Preferably, the drive assembly includes a servo motor, a threaded rod, and a connecting rod. The servo motor is fixedly installed on the top left front outer wall of the filter box. The output end of the servo motor is fixedly connected to the threaded rod, and the connecting rod is threaded onto the outer side of the threaded rod. The longitudinal section of the connecting rod is an inverted "U" shape.

[0010] Preferably, one end of the connecting rod located inside the filter box is fixedly connected to the scraper, the length of the scraper is equal to the width of the filter screen, and the bottom end of the scraper slides against the upper surface of the filter screen.

[0011] Preferably, the slag discharge assembly includes a guide rod, a first pressure plate, a first cross column, a second pressure plate, and a second cross column. There are two guide rods, and the front ends of both guide rods are welded and fixed to the filter box. The first pressure plate is slidably sleeved on the outer side of one end of the guide rod, and the first cross column is fixed to the right side wall of the top of the first pressure plate. The second pressure plate is slidably sleeved on the outer side of the other end of the guide rod, and the second cross column is fixed to the right side wall of the top of the second pressure plate.

[0012] Preferably, both the first pressure plate and the second pressure plate have protrusions on the sides of their bottoms that are close to each other. The protrusions are the same size as the slag discharge port and the two are in contact and sealed.

[0013] Preferably, the right end of the first horizontal column is guided and slidably located in the first guide groove, and the right end of the second horizontal column is guided and slidably located in the second guide groove.

[0014] Preferably, the inflection points of the first guide groove and the second guide groove are on the same horizontal straight line, and the lower half of the second guide groove is vertical.

[0015] Preferably, a guide frame is provided outside the slag discharge port, the guide frame is inclined and one end is fixed to the rear outer wall of the filter box.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, the servo motor is activated to control the rotation of the threaded rod, which in turn controls the connecting rod to move the scraper to the right, pushing the impurities on the filter screen into the narrow space formed between the scraper, the first pressure plate, the second pressure plate, and the inner wall of the filter box. Subsequently, the electric push rod is activated to control the movable plate to move downward. At this time, the vertical section of the second guide groove can keep the second horizontal column and the second pressure plate stationary and stably seal the slag discharge port. Meanwhile, the first guide groove can squeeze the first horizontal column and the first pressure plate to move steadily backward along the guide rod. As the first pressure plate moves backward and gets closer to the second pressure plate, it facilitates the compression effect on the impurities between them, squeezing out the fish oil contained in the impurities and discharging and collecting it through the filter screen, which facilitates the full collection of fish oil and avoids waste.

[0018] As the movable plate moves downward, when the second horizontal column is located in the upper inclined section of the second guide groove, the first and second pressure plates can be controlled to move backward simultaneously, which opens the slag discharge port. The slag discharge port is then opened along with the protrusion of the first pressure plate, making it easy to push impurities out of the filter box through the slag discharge port and into the inclined guide frame. The impurities are then conveniently discharged into the pre-placed recycling box through the guide frame. The slag discharge is quick, convenient, and easy to operate. Attached Figure Description

A guide frame 12 is provided outside the slag discharge port 11. The guide frame 12 is inclined and one end is fixed to the outer rear wall of the filter box 1.

[0030] As a preferred embodiment, based on the above structure, the lower half of the filter box 1 is a funnel-shaped structure, and a discharge port 3 is provided at the bottom of the funnel-shaped structure.

[0031] In this embodiment, the funnel-shaped bottom of the filter box 1 and the discharge port 3 facilitate the discharge of the filtered fish oil.

[0032] As a preferred embodiment, based on the above structure, the drive assembly 4 further includes a servo motor 41, a threaded rod 42, and a connecting rod 43. The servo motor 41 is fixedly installed on the top left front outer wall of the filter box 1. The output end of the servo motor 41 is fixedly connected to the threaded rod 42. The outer side of the threaded rod 42 is threaded with the connecting rod 43. The longitudinal section of the connecting rod 43 is an inverted "U" shape.

[0033] As a preferred embodiment, based on the above structure, the connecting rod 43 is further fixedly connected to the scraper 5 at one end inside the filter box 1. The length of the scraper 5 is equal to the width of the filter screen 2, and the bottom end of the scraper 5 slides against the upper surface of the filter screen 2.

[0034] In this embodiment, starting the servo motor 41 controls the rotation of the threaded rod 42, which in turn controls the connecting rod 43 to move the scraper 5 to the right, making it easier to push and concentrate the impurities on the filter screen 2 for subsequent processing.

[0035] As a preferred embodiment, based on the above structure, the slag discharge assembly 6 further includes a guide rod 61, a first pressure plate 62, a first horizontal column 63, a second pressure plate 64, and a second horizontal column 65. There are two guide rods 61, and the front ends of both guide rods 61 are welded and fixed to the filter box 1. The first pressure plate 62 is slidably sleeved on the outer side of one end of the guide rod 61, and the first horizontal column 63 is fixed to the right side wall of the top of the first pressure plate 62. The second pressure plate 64 is slidably sleeved on the outer side of the other end of the guide rod 61, and the second horizontal column 65 is fixed to the right side wall of the top of the second pressure plate 64.

[0036] As a preferred embodiment, based on the above structure, both the first pressure plate 62 and the second pressure plate 64 have protrusions on the sides of their bottoms that are close to each other. The protrusions are equal in size to the slag discharge port 11 and the two are in contact and sealed.

[0037] In a preferred embodiment, based on the above structure, the right end of the first horizontal column 63 is guided and slidably located in the first guide groove 9, and the right end of the second horizontal column 65 is guided and slidably located in the second guide groove 10.

[0038] In this embodiment, the electric push rod 7 is activated to control the movable plate 8 to move downward. At this time, the vertical section of the second guide groove 10 can keep the second horizontal column 65 and the second pressure plate 64 stationary, while the first guide groove 9 can squeeze the first horizontal column 63 and the first pressure plate 62 to move backward along the guide rod 61. As the first pressure plate 62 moves backward and gets closer to the second pressure plate 64, it is convenient to compress the impurities between them, so that the fish oil contained in the impurities can be fully discharged.

[0039] As a preferred embodiment, based on the above structure, the inflection points of the first guide groove 9 and the second guide groove 10 are on the same horizontal straight line, and the lower half of the second guide groove 10 is vertical.

[0040] In this embodiment, as the movable plate 8 continues to move downward, the first pressure plate 62 and the second pressure plate 64 can move backward simultaneously, which facilitates the discharge of impurities through the slag discharge port 11 and pushes them out of the filter box 1. The slag discharge is quick and convenient, and the operation is simple.

[0041] The working principle of this utility model is as follows:

[0042] In use, first place the collection boxes for fish oil and impurities directly below the filter box 1 and guide frame 12, respectively. Then, add the fish oil to be filtered into the filter box 1. Filter the fish oil using the filter screen 2. The filtered fish oil can be discharged into the collection box through the funnel-shaped structure at the bottom of the filter box 1 and the discharge port 3. After filtration, start the servo motor 41 to control the threaded rod 42 to rotate, and control the connecting rod 43 to drive the scraper 5 to move stably to the right. The scraper 5 can push the impurities filtered out on the filter screen 2 between the scraper 5, the first pressure plate 62, the second pressure plate 64, and the inner wall of the filter box 1. Within the narrow space formed, the electric push rod 7 is then activated to control the movable plate 8 to move downward. At this time, the vertical section of the second guide groove 10 can keep the second horizontal column 65 and the second pressure plate 64 stationary, which facilitates the stable sealing of the slag discharge port 11 by the second pressure plate 64. Meanwhile, the first guide groove 9 can squeeze the first horizontal column 63 and the first pressure plate 62 to move steadily backward along the guide rod 61. As the first pressure plate 62 moves backward and gets closer to the second pressure plate 64, it is convenient to compress the impurities between them. The fish oil contained in the impurities can be squeezed out and discharged through the filter screen plate 2, which facilitates the full collection of fish oil and avoids waste.

[0043] When the second horizontal column 65 is located in the upper inclined section of the second guide groove 10, as the movable plate 8 continues to move downward, the first pressure plate 62 and the second pressure plate 64 can be controlled to move backward simultaneously, which can open the slag discharge port 11. As the protrusion of the first pressure plate 62 enters the slag discharge port 11, it is convenient to push the impurities out of the filter box 1 through the slag discharge port 11 and let them fall into the inclined guide frame 12. It is convenient to discharge the impurities into the pre-placed recycling box through the guide frame 12. The slag discharge is quick and convenient and easy to operate.

[0044] It should be noted that this device is powered by an external power source. The servo motor 41 and electric push rod 7 in the device are existing products, and their specific circuit connection methods and operation control methods are mature technologies, so they will not be described in detail.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
