Description

Technical Field

[0001] This utility model relates to the field of edible oil production technology, and in particular to a flaxseed oil circulating adsorption system. Background Technology

[0002] The refining process of flaxseed oil is one of the important steps in removing impurities, harmful components, and unpleasant flavors from crude oil and improving its stability. Crude oil obtained from flaxseed pressing or extraction contains various natural pigments and impurities. The refining process effectively removes these impurities, preventing harm to the human body, and also improves the appearance and taste of the flaxseed oil.

[0003] One of the main refining processes of flaxseed oil is decolorization using bleaching clay under vacuum conditions. The amount and method of adding bleaching clay are particularly important. Traditionally, bleaching clay is transported by scraper conveyor, which not only generates a lot of dust on site but also makes it impossible to achieve vacuum treatment in the mixing tank, affecting the adsorption effect. To address these issues, we have proposed a flaxseed oil circulating adsorption system. Utility Model Content

[0004] This application provides a flaxseed oil circulating adsorption system, which solves the problem of the mixing tank not being able to be sealed and the ash from the bleaching clay being generated when adding bleaching clay during the flaxseed oil decolorization process.

[0005] This application provides a flaxseed oil circulating adsorption system, including a mixing tank. A feeding hopper is provided on one side of the mixing tank, and a discharge hopper is provided on one side of the feeding hopper. A pulse dust collector is also provided on the top of the mixing tank. The suction end of the pulse dust collector is connected to a suction pipe, which extends into the discharge hopper. A screw feeder is installed on the discharge pipe at the bottom of the pulse dust collector. The discharge end of the screw feeder is fixed on the mixing tank and communicates with the mixing tank.

[0006] Preferably, a flow meter is installed on the liquid addition pipe of the mixing tank.

[0007] Preferably, a filter is also installed on the outlet pipe of the mixing tank.

[0008] Preferably, a preheater is also installed at the end of the liquid outlet pipe.

[0009] Preferably, a high-level level gauge and a low-level level gauge are installed at the hopper of the pulse dust collector.

[0010] Preferably, the feed pipe is equipped with an upper valve and a lower valve.

[0011] Preferably, the screw feeder is inclined.

[0012] Preferably, the mixing tank is also equipped with a liquid level sight glass.

[0013] Preferably, the feeding hopper is supported by a bracket.

[0014] Preferably, the mixing tank is a stirred mixing tank.

[0015] As can be seen from the above technical solution, this application provides a flaxseed oil circulation adsorption system. In use, white clay is first added to the feeding hopper, and then sucked into the pulse dust collector for temporary storage. The white clay enters the screw feeder through the discharge pipe, and the screw feeder adds material according to the set value, specifically according to the proportion of flaxseed oil added. In specific use, the discharge port of the screw feeder needs to be set below the liquid surface, and the mixing tank is in a continuous stirring state. The mixed white clay enters the decolorization tank for decolorization treatment.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a feeding hopper, the feeding hopper can be set up in a separate workshop. The clay is transported to the feeding hopper by forklift or overhead crane and then unloaded into the feeding hopper, reducing the impact on the factory during the unloading process. 2. By setting up a pulse dust collector and suction pipe, the kaolin is transported through negative pressure adsorption, which can effectively reduce the impact on the factory during the transportation process and ensure the on-site environment. 3. The screw feeder not only ensures stable unloading and prevents dust generation, but also guarantees a sealed environment in the mixing tank during the addition of clay, thereby improving oil quality.

[0017] In summary, this application, through the design of the bleaching clay feed, not only improves the efficiency and stability of bleaching clay addition, but also reduces the environmental impact of bleaching clay, and further ensures the sealing of the mixing process, enabling the mixing tank to operate under negative pressure, thereby improving oil quality.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0021] See Figure 1-3 This application discloses a flaxseed oil circulating adsorption system for mixing flaxseed oil before decolorization. Specifically, it involves mixing bleaching clay with a portion of flaxseed oil before adding it to a decolorization tank. This process quickly achieves uniformity of the bleaching clay within the mixing tank. The system includes a mixing tank 1, which is a stirring tank where continuous stirring occurs during the addition of bleaching clay. The stirring structure within the tank is similar to existing technologies. A liquid level sight glass 2 is installed on the mixing tank 1 for real-time monitoring of the liquid level. A feeding hopper 3 is located on one side of the mixing tank 1. This application places the feeding hopper 3 in a separate area specifically for storing and adding bleaching clay. A crane can be installed in this area to transport ton bags containing bleaching clay. During feeding, the ton bags are placed on the feeding hopper 3, and the bottom outlet is opened. A connecting outlet is located on one side of the feeding hopper 3. The bottom of the feeding hopper 3 and the discharge hopper 4 are connected. The material enters the discharge hopper 4 through the feeding hopper 3. The top of the mixing tank 1 is also equipped with a pulse dust collector 8, which transports the bleaching clay by gas conveying. The suction end of the pulse dust collector 8 is connected to a suction pipe 5, which extends into the discharge hopper 4. The suction pipe 5 sucks in the bleaching clay from one side of the discharge hopper 4 and collects it into the pulse dust collector 8. This process ensures that no dust is generated in the refining workshop and can ensure the cleanliness of the refining workshop. A screw feeder 14 is installed on the discharge pipe 11 at the bottom of the pulse dust collector 8. The discharge end of the screw feeder 14 is fixed on the mixing tank 1 and is connected to the mixing tank 1. Finally, the bleaching clay is sent into the mixing tank 1 through the screw feeder 14. The screw feeding method can ensure the sealing inside the mixing tank 1, so that the mixing tank 1 can be vacuumed to make the pressure inside the mixing tank 1 equal to the pressure inside the decolorizing tank, thereby facilitating the transportation between flaxseed oils.

[0022] In this utility model, the discharge port of the screw feeder 14 is installed below the liquid surface, and the screw feeder 14 is inclined to prevent flaxseed oil from entering the screw feeder 14 and ensure feeding.

[0023] In some embodiments, flaxseed oil is first added to the mixing tank 1, with the liquid level higher than the outlet of the screw feeder 14, and then white clay is added according to the amount of oil to mix.

[0024] In this invention, a flow meter 7 is installed on the liquid addition pipe 6 of the mixing tank 1 to monitor the amount of oil added in real time.

[0025] In some embodiments, after the oil volume is added above the screw feeder 14, the mixed clay and linseed oil can be discharged. At the same time, linseed oil is added to the mixing tank 1, and the screw feeder 14 adds materials in proportion according to the flow rate of the flow meter 7, thereby achieving simultaneous discharge and feeding.

[0026] In this invention, a filter 16 is also installed on the outlet pipe 15 of the mixing tank 1. During the discharge process after mixing, the undissolved bleaching clay can be filtered to improve the quality of the bleaching clay entering the decolorizing tank. Furthermore, a preheater 17 is also installed at the end of the outlet pipe 15. The mixture of bleaching clay and linseed oil can be heated before entering the decolorizing tank, thereby reducing the impact on the temperature inside the decolorizing tank.

[0027] In this utility model, a high-level material level meter 9 and a low-level material level meter 10 are installed at the hopper of the pulse dust collector 8 to monitor the material in the pulse dust collector 8, to add material in a timely manner, and to control the maximum feeding amount. Furthermore, the feed pipe 11 is equipped with an upper valve 12 and a lower valve 13, which are used to disconnect the feeding and unloading of the pulse dust collector 8 and the screw feeder 14, respectively.

[0028] In this utility model, the feeding hopper 3 is supported by the bracket 31, which can be used to support the ton bag containing kaolin, making it easy to unload.

[0029] As can be seen from the above technical solution, when using this application, the white clay is first added to the feeding hopper 3, and then sucked into the pulse dust collector 8 for temporary storage. The white clay enters the screw feeder 14 through the discharge pipe 11, and the screw feeder 14 adds material according to the set value. Specifically, it is added according to the proportion of flaxseed oil added. In specific use, the discharge port of the screw feeder 14 needs to be set below the liquid surface, and the mixing tank 1 is in a continuous stirring state. The mixed white clay enters the decolorization tank for decolorization treatment.
