[0002] Oil is an important raw material in food, chemical, bioenergy and other fields, and its processing often faces the problem of oil solidification caused by low temperature environment. Oil can form solid or semi-solid at low temperature, which not only increases the difficulty of transportation and storage, but also directly affects the efficiency and quality of subsequent processing.

The heating device is installed at the bottom of the container, and the heating method is single (such as relying only on bottom heating), so the melting speed of oil is slow, especially when processing a large amount of solidified oil, the production efficiency is low.

DETAILED DESCRIPTION

[0028] The exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0029] EMBODIMENT

[0030] As mentioned in the background, the common oil melting equipment mainly includes a simple heating container or a steam heating device. These devices can achieve basic heating function, but there are many problems in practical application. For example, the traditional stirring blade (such as flat blade or paddle blade) is easy to produce flow dead angle in the stirring process, the heating device is usually installed only at the bottom of the container, the heating mode is single, the melting speed of oil is slow, especially when processing a large amount of solidified oil, the production efficiency is low, therefore, the inventor improves the existing oil machine and designs a new type of overturning and stirring mechanism, which will be described in detail below in combination with the drawings.

[0031] The embodiment provides an oil melting machine overturning and stirring mechanism, referring to Figure 1 , including an oil melting tank body 1 made of high-temperature resistant and corrosion resistant material, usually stainless steel or high-strength alloy steel, to ensure long-term stable operation in high-temperature and oil corrosion environment, and a heater 2 is installed at the bottom of the oil melting tank body 1. The design of the heater 2 can ensure that the oil at the bottom of the oil melting tank melts quickly. The heater 2 is a technical solution known to those skilled in the art, for example, the existing patent number CN21838653U discloses an oil processing softening device, which is symmetrically installed at the bottom of the outer cylinder. Whether it is an existing device or an existing patent, it is widely used, so it is not described in detail in this scheme. Secondly, the overturning and stirring shaft 3 is installed at the top of the middle position in the oil melting tank body 1, and the top end of the overturning and stirring shaft 3 penetrates the oil melting tank body 1 and is connected with the power assembly 4. In this scheme, the power assembly 4 includes a driving motor 41 and a speed reducer 42 connected with the output end of the driving motor 41, the speed reducer 42 is connected with an output shaft, the output shaft is connected with the overturning and stirring shaft 3, and the driving motor 41 transmits power to the overturning and stirring shaft 3 through the speed reducer 42, so that the overturning and stirring shaft 3 operates at a stable speed.

[0032] On the basis of the above structure, in combination with Figure 1 and Figure 4 , the support frame 13 is installed at the top of the oil melting tank body 1, the support disc 14 is arranged on the support frame 13, and the support disc 14 is rotatably connected with the support frame 13. The overturning and stirring shaft 3 penetrates the support disc 14 and the support frame 13, and is fixedly connected with the support disc 14 through the outer edge surface, so as to ensure the stability and reliability of the overturning and stirring shaft 3 during rotation.

[0033] In addition, in order to facilitate feeding and discharging, the feeding port 15 is arranged at the upper end of the oil melting tank body 1 for feeding solid oil, and the discharging port 16 is arranged at the lower end of the side surface for discharging melted oil.

[0034] In this embodiment, in combination with Figure 2The stirring shaft 3 extends vertically downward in the oil tank body 1, and a plurality of sets of stirring blades 5 are installed on the outer end face of the stirring shaft 3, and two stirring blades 5 are arranged on both sides of the stirring shaft 3, and the length of the stirring blade 5 described below refers to the overall length of each set of blades. The stirring blades 5 are distributed along the length direction of the stirring shaft 3, and usually three stirring blades 5 are arranged, and the extension directions of the upper and lower adjacent stirring blades 5 are perpendicular to each other. This design can effectively break the solidification state of the oil, and avoid the flow dead angle problem caused by the traditional flat blade or paddle blade. The middle stirring blade 5 has a longer extension length, which is usually not less than 1 / 2 of the width of the oil tank body 1, and the upper and lower stirring blades 5 have a shorter length, which is usually less than 1 / 2 of the width of the oil tank body 1. This multi-level stirring design can cover different areas of the oil tank, ensure uniform stirring of the oil, and expand the stirring range.

[0035] The difference between the present scheme and the prior art is that the present scheme designs a new heating structure which can cooperate with the heater 2 at the bottom of the oil tank body 1. The cooperation of the two can increase the heating range of the oil in the tank body, greatly accelerating the melting of the oil. Specifically, the upper end of the stirring shaft 3 is provided with a sleeve 9, and the upper end here refers to the part of the stirring shaft 3 located in the oil tank body 1. The sleeve 9 is fixed with the stirring shaft 3 and can rotate with it. Two water pipes 6 are installed on both sides of the sleeve 9, which are L-shaped with the opening downward, and the bottom end is connected with an inclined pipe 7. The two inclined pipes 7 extend downward and are connected to a branch pipe 11. The branch pipe 11 is rotatably and sealingly connected to the water inlet 12 at the bottom end of the oil tank body 1. The water inlet 12 is in communication with the external water supply pipe 8 for conveying hot water or steam into the water pipe 6. Although the heater 2 is a prior art component, it can accelerate the melting of the oil when used with the water pipe 6 of the present scheme.

[0036] In addition, the design of the water pipe 6 not only plays a heating role, but also can rotate with the stirring shaft 3 through the sleeve 9, thereby playing a role in stirring the oil in the tank body, further accelerating the melting of the oil.

[0037] On the basis of the above structure, the horizontal end length of the water pipe 6 is greater than half the length of the longest stirring blade 5. In the present scheme, the vertical end of the water pipe 6 is arranged close to the inner wall of the oil tank body 1, but the two do not contact, so as to ensure that the hot water or steam can cover a larger heating area, and can be staggered with the stirring blades 5 in the stirring area.

[0038] In the embodiment, the water pipe 6 is arranged in the sleeve 9, and the sleeve 9 is arranged on the stirring shaft 3. Figure 3, two arc-shaped blades 10 are installed at the front and rear ends of the water pipes 6, extending from the L-shaped corner of one water pipe 6 to the L-shaped end of the other water pipe 6, and bending towards the inner wall of the oil tank body 1 in the middle. The curved shape of the arc-shaped blades 10 can better agitate the oil, and the setting of the arc-shaped blades 10 greatly improves the stirring range in cooperation with the stirring blades 5.

[0039] In actual work, first, the oil at the bottom of the oil tank is heated by the heater 2 to make it preliminary melt. Then, the power assembly 4 is started to drive the stirring shaft 3 to rotate the stirring blades 5 and the water pipes 6. The stirring blades 5 stir the oil in the central area of the oil tank, while the water pipes 6 and the arc-shaped blades 10 focus on the stirring of the edge area, and through the synergistic effect, the overall oil stirring is uniform.

[0040] At the same time, the external water supply pipe 8 sends hot water or steam into the water pipes 6 through the water inlet 12. The hot water or steam is evenly distributed to each area of the oil tank through the inclined pipe 7 and the water pipe 6, forming a dynamic heating system. The rotation of the water pipes 6 and the arc-shaped blades 10 further enhances the heat transfer effect, ensuring that the oil melts quickly and uniformly.
