Description

Technical Field

[0001] This utility model belongs to the field of oil decolorization technology, specifically relating to a novel oil decolorization device. Background Technology

[0002] Oil decolorization equipment is used to remove pigments and impurities from oils and fats. It is widely used in the refining process of edible oils, vegetable oils, and animal oils, especially in the refining of edible oils and vegetable oils, to improve the color, taste, and quality of the oils. The main purpose of decolorization is to remove colored substances, impurities, and free fatty acids from oils and fats, thereby improving their appearance and stability.

[0003] Currently, the adsorption decolorization method is commonly used in industry. This involves adding adsorbents such as activated clay and activated carbon to the oil, mixing and stirring them under heating and vacuum conditions, and then filtering and separating them. However, during the decolorization process, the flow path between the oil and the adsorbent in the tower is relatively short, resulting in insufficient effective reaction contact time. In order to meet the decolorization standard, it is often necessary to extend the stirring time or increase the amount of adsorbent, which in turn leads to an increase in production costs. Utility Model Content

[0004] The purpose of this invention is to provide a novel oil decolorization device that can increase the reaction contact time between oil and adsorbent, improve the decolorization effect and efficiency, and further reduce production costs.

[0005] The specific technical solution adopted by this utility model is as follows: A novel oil decolorization device includes a decolorization tank. The top of the decolorization tank is connected to an oil inlet pipe and an adsorbent feeding pipe, and the bottom of the decolorization tank is connected to an oil outlet pipe. At least two baffles are installed inside the decolorization tank and are staggered and connected to the inner wall of the tank. A heating tube is arranged on the surface of the decolorization tank and is wound in a ring around its outer surface. An insulation sleeve is fitted over the surface of the decolorization tank, and the heating tube is located inside the insulation sleeve. A vacuum pump is installed at the top of the decolorization tank and connected to it. A stirring motor is connected to the top of the decolorization tank, and a stirring shaft is connected to the output end of the bottom of the stirring motor. The stirring shaft passes through the baffles in sequence, and stirring blades are connected to the surface of the stirring shaft.

[0006] Preferably, the side surface of the oil outlet pipe is inclinedly connected to a drain pipe, and a filter cylinder is detachably installed inside the drain pipe, extending inclinedly into the interior of the oil outlet pipe.

[0007] Preferably, the top of the decolorizing tank is provided with a circular hole, and the inner wall of the circular hole is connected to an observation window.

[0008] Preferably, the top of the adsorbent feeding tube is connected to a sealing cover plate, which is made of stainless steel.

[0009] Preferably, the stirring blade is a turbine-type stirring blade, which has multiple layers and is located between two adjacent baffles.

[0010] Preferably, the bottom of the decolorizing tank is conical, and its diameter is smaller than the diameter of the main body of the decolorizing tank.

[0011] Preferably, one side of the baffle plate is provided with a flow port, which forms an S-shaped flow channel in the internal space of the decolorization tank.

[0012] The technical effects achieved by this utility model are as follows: In this invention, when decolorizing oil, the adsorbent is first added to the decolorization tank through the adsorbent feeding pipe. Then, the oil is transported into the decolorization tank through the oil inlet pipe. The oil will bend under the baffles, which not only increases the contact area between the oil and the baffles, but also allows the oil to flow downward along the flow port in an S-shaped channel under the action of multiple baffles. This greatly increases the contact time and contact area between the oil and the adsorbent in the decolorization tank. At the same time as decolorization, the vacuum pump is run to evacuate the inside of the decolorization tank. The heating pipe and stirring system are used to heat and stir the decolorization tank and the oil inside, which can improve the reaction rate and make the decolorization process more efficient.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-5 As shown, a novel oil decolorization device includes a decolorization tank 1. The top of the decolorization tank 1 is connected to an oil inlet pipe 101 and an adsorbent feeding pipe 102, and the bottom of the decolorization tank 1 is connected to an oil outlet pipe 103. The decolorization tank 1 is equipped with baffles 104 inside. There are at least two baffles 104, which are staggered and connected to the inner wall of the decolorization tank 1. The stirring blades 110 are turbine-type stirring blades 110. The stirring blades 110 are multi-layered and located between two adjacent baffles 104. Through the design of the baffles 104 and the S-shaped flow channel, the flow path of the oil in the decolorization tank 1 is extended, thereby increasing the contact area and time between the oil and the adsorbent. This allows the pigments and impurities in the oil to react more fully with the adsorbent, improving the decolorization efficiency and decolorization effect. A heating tube 105 is provided on the surface of the decolorizing tank 1, and is wound in a ring around the outer surface of the decolorizing tank 1. A heat insulation sleeve 106 is fitted over the surface of the decolorizing tank 1, and the heating tube 105 is located inside the heat insulation sleeve 106. A vacuum pump 107 is installed on the top of the decolorizing tank 1 and is connected to the decolorizing tank 1. A stirring motor 108 is connected to the top of the decolorizing tank 1. A stirring shaft 109 is connected to the output end of the bottom of the stirring motor 108. The stirring shaft 109 passes through the baffle 104 in sequence. Stirring blades 110 are connected to the surface of the stirring shaft 109, and the vacuum pump 107 circulates heat from the inside of the decolorizing tank 1. Vacuuming can reduce the vapor pressure of oil, promote the removal of impurities, and reduce the loss of volatile substances in oil. In a vacuum environment, insoluble impurities in oil are more easily adsorbed by the adsorbent, thereby improving the decolorization efficiency. The combination of heating tube 105 and stirring system can help the oil and adsorbent mix more evenly, preventing the adsorbent from settling or agglomerating. Heating the oil in decolorization tank 1 can reduce the viscosity of the oil, improve its fluidity and permeability, help the oil to contact the adsorbent better, and increase the reaction rate in the decolorization process.

[0017] like Figures 1-3 As shown, the side surface of the oil outlet pipe 103 is inclinedly connected to the drain pipe 201. The drain pipe 201 is detachably installed with a filter cylinder 202, which extends inclinedly into the interior of the oil outlet pipe 103. When the decolorized grease is discharged from the drain pipe 201, some impurities in the grease will be intercepted and filtered by the filter cylinder 202 inside the drain pipe 201. Then, the intercepted and filtered impurities can be smoothly discharged along the inclined drain pipe 201, avoiding the accumulation of impurities in the filter cylinder 202 and the interior of the drain pipe 201.

[0018] like Figure 1 As shown, a circular hole 301 is provided on the top of the decolorizing tank 1, and an observation window 302 is connected to the inner wall of the circular hole 301. Through the observation window 302, the operator can clearly see the situation inside the decolorizing tank 1, such as color changes and reaction speed, so that the operator can monitor the decolorization effect inside the decolorizing tank 1 in real time and ensure that the decolorization process meets the requirements.

[0019] like Figure 1 and Figure 3 As shown, a sealing cover 4 is connected to the top of the adsorbent feeding pipe 102. The sealing cover 4 is made of stainless steel. The sealing cover 4 effectively prevents gas and heat from leaking from the adsorbent feeding pipe 102, ensuring a sealed vacuum state during the decolorization process. Furthermore, the stainless steel sealing cover 4 has excellent corrosion resistance, resisting the erosion of adsorbents, chemicals, or other corrosive substances. This effectively extends the service life of the sealing cover 4 and avoids damage or functional loss due to corrosion.

[0020] like Figure 3 and Figure 4 As shown, the stirring blade 110 is a turbine-type stirring blade 110. The stirring blade 110 has multiple layers and is located between two adjacent baffles 104. When the turbine-type stirring blade 110 rotates, it generates strong fluid shear force and centrifugal force, which can quickly break the sticky layer between the oil and the adsorbent, promote the full mixing of materials, and the multiple layers of stirring blades 110 can increase the stirring area and the depth of stirring action. Each layer of stirring blades 110 can apply force to the fluid, thereby improving the stirring effect, reducing the stirring time, and improving the effect and efficiency of oil decolorization.

[0021] like Figure 3 As shown, the bottom of the decolorizing tank 1 is conical, and its diameter is smaller than the main body diameter of the decolorizing tank 1. The conical bottom design allows the oil to flow towards the bottom when it is discharged from the decolorizing tank 1, forming a natural flow direction, avoiding the retention and accumulation of oil at the bottom of the decolorizing tank 1, and allowing the decolorized oil to be discharged smoothly.

[0022] The working principle of this utility model is as follows: When decolorizing oil, the adsorbent is first added to the decolorization tank 1 through the adsorbent feeding pipe 102. Then, the oil is transported into the decolorization tank 1 through the oil inlet pipe 101. The oil will bend under the baffle 104, which not only increases the contact area between the oil and the baffle 104, but also allows the oil to flow downward along the flow port 5 under the action of multiple baffles 104, forming an S-shaped flow channel. This greatly increases the contact time and contact area between the oil and the adsorbent in the decolorization tank 1. At the same time as decolorization, the vacuum pump 107 is run to evacuate the inside of the decolorization tank 1. The heating pipe 105 and the stirring system are used to heat and stir the decolorization tank 1 and the oil inside, which can improve the reaction rate and make the decolorization process more efficient.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
