Description

Technical Field

[0001] This utility model relates to the field of DHA algal oil filtration technology, specifically a filtration device for DHA algal oil. Background Technology

[0002] DHA algal oil is a high-value-added functional oil rich in docosahexaenoic acid (DHA), which is widely used in infant formula, health products and pharmaceuticals. Its production process requires the extraction of crude oil from microalgae cells through physical or chemical methods, followed by a multi-step purification process to remove impurities (such as cell debris, pigments, free fatty acids, etc.). Traditional filtration technologies (such as plate and frame filtration, centrifugation or membrane filtration) are often used in the primary purification stage of algal oil, but these methods usually rely on a single filtration medium or mechanical separation principle, which makes it difficult to meet the efficiency requirements of high-precision filtration and large-scale production.

[0003] Traditional filtration devices have significant limitations in the application of DHA algal oil. Plate and frame filtration and centrifugation have low retention efficiency for micron-sized particles and are prone to clogging of filter media due to the adhesiveness of algal oil. Frequent shutdowns for cleaning reduce production efficiency. Although precision membrane filtration can improve purity, high operating pressure may accelerate algal oil oxidation and affect product stability. Utility Model Content

[0004] In order to overcome the problems of low retention efficiency of micron-sized particles in the existing plate and frame filtration and centrifugal separation of DHA algal oil filtration device, easy clogging of filter media due to the adhesion of algal oil, and frequent shutdown for cleaning which reduces production efficiency.

[0005] The technical solution of this utility model is: a filtration device for DHA algal oil, including a box, a moving mechanism opened on the side of the box, a defrosting mechanism disposed in the moving mechanism, a first filtration mechanism fixedly installed below the defrosting mechanism, and a second filtration mechanism fixedly installed below the first filtration mechanism. The moving mechanism includes a slide groove 1 on the left side of the inner wall of the box and a slide groove 2 on the right side of the inside of the box. The defrosting mechanism includes a defrosting chamber disposed in slide 1 and slide 2, a defrosting trough disposed inside the defrosting chamber, a defrosting box disposed in the defrosting trough, a sealing plate fixedly installed on the top of the defrosting box, a drainage trough disposed on the top of the sealing plate, defrosting holes disposed on both sides of the drainage trough, a paddle fixedly installed inside the defrosting holes, a rotating rod fixedly installed on the side of the defrosting box, a rotating handle fixedly installed on the side of the rotating rod, a fixed handle fixedly installed on the side of the defrosting chamber, and a counterweight fixedly installed at the bottom of the defrosting chamber. The first filtration mechanism includes a first filter box fixedly installed below the defrosting mechanism, a filter screen fixedly installed inside the first filter box, a connecting pipe fixedly installed at the bottom of the first filter box, and a solenoid valve disposed on the side of the connecting pipe.

[0006] Preferably, the second filtration mechanism includes a second filter box fixedly installed below the first filtration mechanism, a weighing plate fixedly installed on the top of the second filter box, a through hole opened on the top of the weighing plate, a first silk net fixedly installed inside the second filter box, and a second silk net fixedly installed at the bottom of the first silk net.

[0007] Preferably, a sealed door is provided below the surface of the enclosure.

[0008] Preferably, a glass observation window is fixedly installed on the top of the enclosure.

[0009] Preferably, four support legs are fixedly installed on both sides of the box, and anti-slip pads are fixedly installed on the bottom of each of the four support legs.

[0010] Preferably, four sets of thawing holes are provided, and the four sets of thawing holes are located on both sides of the drainage groove.

[0011] The beneficial effects of this utility model are: 1. This utility model adopts a split-type thawing box design for the thawing mechanism, combined with a stirring blade and a heat exchange structure for thawing holes, which can quickly and evenly melt solidified algal oil raw materials, avoiding DHA oxidation loss caused by local overheating. The moving mechanism, together with the sliding groove, enables flexible pulling of the thawing box, which is convenient for feeding and maintenance. The solenoid valve of the first filtration mechanism can accurately control the coarse filtration flow rate, while the second filtration mechanism further removes micron-sized impurities through silk mesh gradient filtration. The synergistic effect of the two stages ensures the high light transmittance and low acid value of algal oil. 2. This utility model achieves real-time monitoring of the filtration process through a glass observation window and a weighing plate. The support legs and anti-slip pads enhance the equipment's resistance to displacement in a vibration environment. The multiple distribution of thawing holes and the design of the drainage channel optimize heat transfer efficiency and shorten the pretreatment time. The sealed door and counterweight effectively prevent external contamination and equipment shaking. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] A filtration device for DHA algal oil, according to Figures 1-5 As shown, it includes a box body 1, a moving mechanism 2 opened on the side of the box body 1, a defrosting mechanism 3 disposed in the moving mechanism 2, a first filter mechanism 4 fixedly installed below the defrosting mechanism 3, and a second filter mechanism 5 fixedly installed below the first filter mechanism 4. The moving mechanism 2 includes a first slide groove 201 opened on the left side of the inner wall of the housing 1 and a second slide groove 202 opened on the right side of the inside of the housing 1. The defrosting mechanism 3 includes a defrosting chamber 301 disposed in slide 1 201 and slide 2 202, a defrosting groove 302 opened inside the defrosting chamber 301, a defrosting box 303 disposed in the defrosting groove 302, a sealing plate 304 fixedly installed on the top of the defrosting box 303, a diversion groove 305 opened on the top of the sealing plate 304, defrosting holes 306 opened on both sides of the diversion groove 305, a paddle 307 fixedly installed inside the defrosting hole 306, a rotating rod 308 fixedly installed on the side of the defrosting box 303, a rotating handle 309 fixedly installed on the side of the rotating rod 308, a fixed handle 310 fixedly installed on the side of the defrosting chamber 301, and a counterweight 311 fixedly installed at the bottom of the defrosting chamber 301. The first filtration mechanism 4 includes a first filter box 401 fixedly installed below the defrosting mechanism 3, a filter screen 402 fixedly installed inside the first filter box 401, a connecting pipe 403 fixedly installed at the bottom of the first filter box 401, and a solenoid valve 404 provided on the side of the connecting pipe 403.

[0015] according to Figure 4 and Figure 5As shown, the second filtration mechanism 5 includes a second filter box 501 fixedly installed below the first filtration mechanism 4, a weighing plate 502 fixedly installed on the top of the second filter box 501, a through hole 503 opened on the top of the weighing plate 502, a first silk mesh 504 fixedly installed inside the second filter box 501, and a second silk mesh 505 fixedly installed at the bottom of the first silk mesh 504.

[0016] It should be noted that the algal oil, after being pre-treated by the first filtration mechanism 4, enters the second filtration box 501 through the connecting pipe 403. It first flows through the through holes 503 on the weighing plate 502 for uniform distribution, and then passes through the first silk screen 504 and the second silk screen 505 for gradient filtration. The first silk screen 504 intercepts larger particulate impurities, while the second silk screen 505 further filters out fine suspended matter, ultimately achieving high-precision purification of the algal oil.

[0017] according to Figure 1 As shown, a sealing door 6 is provided on the lower surface of the box 1.

[0018] It should be noted that during maintenance or cleaning, the internal filter mechanism can be quickly accessed by opening the sealed door 6, enabling convenient equipment inspection and component replacement.

[0019] according to Figure 1 As shown, a glass observation window 7 is fixedly installed on the top of the box 1.

[0020] It should be noted that the transparent tempered glass material enables visual monitoring, allowing operators to directly observe the flow of algal oil inside the chamber 1, the working status of the filter media, and changes in liquid level.

[0021] according to Figure 1 As shown, four support legs 8 are fixedly installed on both sides of the box body 1, and anti-slip pads 9 are fixedly installed on the bottom of the four support legs 8.

[0022] It should be noted that the symmetrically distributed rigid support structure provides stable support for the entire filtration device, and the elastic material of the anti-slip pad 9 increases the static friction between the equipment and the ground, effectively preventing equipment displacement caused by vibration or operation during the filtration process, and ensuring the stability and safety of the device during operation.

[0023] according to Figure 2 As shown, there are four sets of thawing holes 306, which are located on both sides of the drainage channel 305.

[0024] It should be noted that the thawing hole (306) is designed with four sets of symmetrically distributed on both sides of the diversion groove (305) to form a bidirectional heat exchange channel, so that the heat medium can circulate evenly and achieve rapid and uniform thawing of algal oil.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
