Description

Technical Field

[0001] This utility model relates to the field of blended oil technology, specifically to a blended oil additive dissolving tank. Background Technology

[0002] In the refining and blending processes of edible oils, to prevent uneven dispersion, clumping, and sedimentation of powdered or granular antioxidants, defoamers, nutritional fortifiers, and other trace additives in bulk oils, the industry commonly uses specialized dissolving tanks to prepare additive mother liquor. This dissolving tank mainly consists of a stainless steel tank body, a heating jacket, a high-speed stirrer, and a temperature control system. During operation, heating and strong shearing circulation promote the wetting, dispersion, and dissolution of additives in the base oil or solvent, forming a uniform mother liquor. This ensures the uniformity and quality stability of the final product during subsequent online mixing.

[0003] However, in practical applications, this conventional dissolving tank has significant shortcomings: the added powdered additives, due to their significantly higher density than the solvent, settle rapidly under the influence of surface tension and viscous resistance, forming a dense accumulation layer at the bottom of the tank. Although the agitator can drive macroscopic liquid flow, the corner areas at the bottom of the tank are dead zones, making it difficult for the agitation energy to penetrate the interior of the accumulation and effectively disperse it. As a result, the dissolution of the additives is forced into a slow, layer-by-layer dissolution process—only when the surface particles dissolve and detach can the internal particles come into contact with the solvent. The thicker and denser the accumulation, the more severe the lag in deep dissolution, significantly extending the time required for complete dissolution of a single batch, becoming a bottleneck for production line capacity. At the same time, the extended agitation and heat preservation time to compensate for uneven mixing not only significantly increases heat and electricity consumption but also easily leads to the deactivation of heat-sensitive nutrient fortifiers under prolonged heating, damaging the nutritional quality and shelf-life stability of the finished oil.

[0004] In summary, due to structural limitations, existing dissolving tanks tend to cause powdered and granular additives to accumulate densely at the bottom, preventing rapid and sufficient contact with the solvent, resulting in a slow and inefficient dissolution process. Therefore, effectively preventing additive accumulation at the bottom of the dissolving tank and promoting rapid and uniform contact with the solvent, thereby significantly shortening dissolution time and improving dissolution efficiency, has become a pressing technical problem that needs to be solved in this field. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a blending oil additive dissolving tank, which has the advantage of high dissolving efficiency. It solves the problem that existing dissolving tanks, due to structural limitations, cause powdered and granular additives to easily accumulate densely at the bottom of the tank, making it impossible for them to quickly and fully contact the solvent, resulting in a slow and inefficient dissolving process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a blending oil additive dissolving tank, comprising a dissolving tank, wherein a stirring mechanism is provided on the dissolving tank, and an air filling mechanism is provided between the stirring mechanism and the dissolving tank; The stirring mechanism includes a motor fixedly installed on the top of the dissolving tank, and a rotating shaft extending into the interior of the dissolving tank is fixedly installed at the output end of the motor. A first stirring impeller and a second stirring impeller are fixedly installed on the surface of the rotating shaft. The inflation mechanism includes a bellows fixedly installed on the side surface of the dissolving tank. A drive shaft passing through the top of the bellows is rotatably installed inside the bellows. Fan blades located inside the bellows are fixedly installed on the surface of the drive shaft. A distributor is fixedly installed at the bottom of the inner cavity of the dissolving tank. A connecting pipe is fixedly installed between the distributor and the bottom of the bellows. A first pulley is fixedly installed on the surface of the drive shaft. A second pulley is fixedly installed on the surface of the shaft. A drive belt that engages with the first pulley is sleeved on the surface of the second pulley.

[0007] Furthermore, the first stirring impeller is located above the second stirring impeller, and the second stirring impeller is close to the bottom of the dissolving tank; the first stirring impeller is a radial flow impeller, and the second stirring impeller is an axial flow impeller.

[0008] Furthermore, a support plate is fixedly installed inside the bellows, and the drive shaft is rotatably mounted on the surface of the support plate, and the drive shaft is rotatably connected to the bellows.

[0009] Furthermore, the top surface of the bellows is provided with multiple evenly distributed air inlets.

[0010] Furthermore, the distributor includes a gas distribution ring, on the inner surface of which a plurality of evenly distributed gas distribution pipes are fixedly installed, and each gas distribution pipe has a plurality of air outlet holes on its surface.

[0011] Furthermore, a plurality of support rods are fixedly installed on the top of the dissolving tank, and an mounting plate is fixedly installed on the top of the support rods. The motor is fixedly installed on the upper surface of the mounting plate.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: This blending oil additive dissolving tank connects the second pulley on the rotating shaft to the first pulley on the drive shaft via a transmission belt, allowing a single motor to simultaneously drive stirring and aeration. This simplifies the structure, reduces costs, and ensures synchronized operation and energy efficiency. In the aeration mechanism, the motor drives the fan blades to generate airflow, which is then delivered to the distributor at the bottom of the dissolving tank via a connecting pipe. The rising bubbles directly impact and agitate the bottom additive deposit layer, using pneumatic disturbance to achieve loose fluidization of the additive layer, which helps to break up the dead zone at the bottom of the tank. At the same time, a double-layer stirring impeller is installed on the rotating shaft to form a composite flow field, enhancing the circulating mixing of liquid layers at different heights and promoting uniform dispersion of the additive.

[0015] 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.

[0016] Please see Figures 1 to 4 The blending oil additive dissolving tank in this embodiment includes a dissolving tank 1, a stirring mechanism 2 is provided on the dissolving tank 1, and an air filling mechanism 3 is provided between the stirring mechanism 2 and the dissolving tank 1.

[0017] The stirring mechanism 2 includes a motor 21 fixedly installed on the top of the dissolving tank 1. A rotating shaft 22 extending into the interior of the dissolving tank 1 is fixedly installed at the output end of the motor 21. A first stirring impeller 23 and a second stirring impeller 24 are fixedly installed on the surface of the rotating shaft 22.

[0018] The inflation mechanism 3 includes a bellows 31 fixedly installed on the side surface of the dissolving tank 1. A drive shaft 32 is rotatably installed inside the bellows 31, passing through the top of the bellows 31. A fan blade 33 located inside the bellows 31 is fixedly installed on the surface of the drive shaft 32. A distributor 34 is fixedly installed at the bottom of the inner cavity of the dissolving tank 1. A connecting pipe 35 is fixedly installed between the distributor 34 and the bottom of the bellows 31. A first pulley 36 is fixedly installed on the surface of the drive shaft 32. A second pulley 37 is fixedly installed on the surface of the rotating shaft 22. A drive belt 38 that is sleeved on the surface of the second pulley 37 and sleeved with the first pulley 36 is also sleeved on the surface of the second pulley 37.

[0019] It should be noted that the first impeller 23 is located above the second impeller 24, and the second impeller 24 is close to the bottom of the dissolving tank 1. The first impeller 23 is a radial impeller, and the second impeller 24 is an axial impeller. The first impeller 23 can generate radial discharge with high shear force, which helps to crush and initially disperse particles. The second impeller 24, which is close to the bottom of the tank, can generate strong axial thrust, which can effectively lift and suck up the sediment in the center of the bottom of the tank. This allows the second impeller 24 to transport the high-concentration mixture from the bottom upwards, while the first impeller 23 is responsible for the overall dispersion in the upper part of the tank, forming an axial circulation and preventing particles from depositing at the bottom of the dissolving tank 1.

[0020] It should be noted that a support plate 4 is fixedly installed inside the bellows 31, and the drive shaft 32 is rotatably mounted on the surface of the support plate 4. The drive shaft 32 is rotatably connected to the bellows 31. The support plate 4 provides an intermediate support point for the drive shaft 32, which can reduce the radial runout and vibration of the drive shaft 32 when it rotates at high speed.

[0021] It should be noted that the top surface of the wind box 31 has multiple evenly distributed air inlets 5, which helps to provide a uniform and dispersed airflow inlet for the rotation of the fan blades 33.

[0022] In this embodiment, the distributor 34 includes a gas distribution ring 341. Multiple evenly distributed gas distribution pipes 342 are fixedly installed on the inner surface of the gas distribution ring 341. Multiple gas outlet holes 343 are opened on the surface of each gas distribution pipe 342, which is conducive to the uniform dispersion of the airflow into a large number of bubbles and simultaneous release from multiple positions at the bottom of the tank, thereby agitating the accumulated layer at the bottom of the tank and promoting full contact between the additive and the solvent.

[0023] In this embodiment, a plurality of support rods 6 are fixedly installed on the top of the dissolving tank 1, and an mounting plate 7 is fixedly installed on the top of the support rods 6. The motor 21 is fixedly installed on the upper surface of the mounting plate 7.

[0024] It should be noted that the dissolving tank 1 is equipped with a feeding port at the top and a discharge valve that can be closed and opened at the bottom.

[0025] It should be noted that a one-way valve is provided inside the vent 343. When gas is released from the vent 343, the one-way valve opens to the outside of the vent 343. When gas is not released from the vent 343, the one-way valve closes to prevent solvent from entering the gas distribution pipe 342.

[0026] The working principle of the above embodiments is as follows: The motor 21 is started, which drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the second pulley 37 fixed on it to rotate synchronously, and transmits the power to the first pulley 36 through the transmission belt 38, thereby driving the transmission shaft 32 to rotate.

[0027] During stirring, the rotating shaft 22 drives the first stirring impeller 23 and the second stirring impeller 24 to rotate. The first stirring impeller 23, located on the upper layer, is radial, generating a radial flow with high shear force, which initially disperses the added additive particles and pushes them radially towards the tank wall. The second stirring impeller 24, located near the bottom of the dissolving tank 1, is axial, generating a strong axial thrust, which draws the material in the central area of ​​the tank bottom upward, forming an axial circulation flow. At the same time, the drive shaft 32 drives the fan blades 33 inside the bellows 31 to rotate at high speed. Outside air is evenly drawn in through the air inlet 5 at the top of the bellows 31 and pressurized by the fan blades 33 to form a pressurized airflow. This airflow is transported through the connecting pipe 35 connected to the bottom of the bellows 31 to the distributor 34 fixed at the bottom of the inner cavity of the dissolving tank 1. The pressurized gas is distributed to each gas distribution pipe 342 through the gas distribution ring 341, and finally sprayed out simultaneously from multiple points at the bottom of the tank in the form of a large number of fine bubbles through the densely distributed air outlets 343 on the pipe wall, which can disturb the material accumulation layer.
