Description

Technical Field

[0001] This utility model relates to the field of heat transfer oil production technology, and more specifically to a heat transfer oil production and blending device. Background Technology

[0002] Heat transfer oil is a special industrial oil belonging to the category of organic heat carriers. In industrial production, it typically achieves indirect heat transfer through liquid-phase or gas-phase circulation. During the production process, a blending tank is required to thoroughly stir and mix the base oil with various functional additives.

[0003] However, most existing blending tanks adopt a fixed paddle stirring structure, which easily causes the oil in the tank to form a stable annular vortex during the stirring process, resulting in insufficient fluid shear force. Especially when adding a variety of additives with different properties, this flow pattern is difficult to effectively disperse the clusters and achieve uniform mixing, thus affecting the finished product quality and production efficiency of the heat transfer oil. Therefore, it is urgent to design a heat transfer oil production blending device to solve the above problems. Utility Model Content

[0031] A heat transfer oil production and blending device includes a blending tank 1, a tank cover 2, a drive assembly 3, a stirring shaft 4, and a heating pipe 5.

The device also includes:

[0032] Three sets of blade assemblies 6 are equidistantly distributed on the stirring shaft 4. Each set consists of two blade assemblies 6, which are symmetrically fixed on the stirring shaft 4. Each blade assembly 6 includes two stirring blades 601, which are symmetrically fixed on the stirring shaft 4.

[0033] The turbulence assembly 7 includes two rotating blocks 701, which are symmetrically rotated and installed between two stirring blades 601.

[0034] The push assembly 8 includes a lifting rod 802, which is slidably installed inside the stirring shaft 4;

[0035] The transmission assembly 9 includes a crossbar 901 and a strip plate 902. The crossbar 901 is slidably installed between two stirring blades 601 and slides through the stirring shaft 4. The strip plate 902 is fixedly installed at one end of the crossbar 901 and is slidably connected to two rotating blocks 701. The other end of the crossbar 901 is in slidable contact with the lifting rod 802.

[0036] Specifically, the drive assembly 3 includes a first bracket 301, a second bracket 302, and a motor 303. The first bracket 301 is fixedly installed on the top of the can lid 2, the second bracket 302 is fixedly installed on the top of the first bracket 301, and the motor 303 is fixedly installed on the top of the second bracket 302.

[0037] In this embodiment, the stirring shaft 4 is fixedly connected to the output end of the motor 303, and starting the motor 303 will drive the stirring shaft 4 and the stirring blade 601 to rotate.

[0038] Specifically, vertical grooves 602 are provided on the side where the two stirring blades 601 are in contact with each other, and two rotating blocks 701 are symmetrically rotated and installed in the vertical grooves 602. The turbulence assembly 7 also includes four rotating shafts 702, which are fixedly installed on both sides of the two rotating blocks 701 respectively, and the rotating shafts 702 are rotatably installed in the stirring blades 601.

[0039] In this embodiment, the rotating block 701 can rotate within the vertical groove 602 with the rotating shaft 702 as the center, thereby causing the entire turbulence assembly 7 to be disturbed in the oil swirling flow.

[0040] Specifically, the spoiler assembly 7 also includes two L-shaped rods 703, four rotating sleeves 704, and several spoilers 705. The two L-shaped rods 703 are fixedly installed on the two rotating blocks 701 respectively, the four rotating sleeves 704 are rotatably installed on the outside of the two L-shaped rods 703 respectively, and the spoilers 705 are circumferentially fixedly installed on the rotating sleeves 704.

[0041] In this embodiment, the rotating block 701 and the L-shaped rod 703 will rotate with the rotation of the stirring blade 601, and the rotating sleeve 704 and the baffle 705 will also rotate with the rotation of the L-shaped rod 703, thus disturbing the oil swirl.

[0042] Specifically, the aerodynamic component 7 also includes two fixed blocks 707, and each of the two rotating blocks 701 has a slot 706. The two fixed blocks 707 are fixedly installed in the two slots 706 respectively. The strip plate 902 has two symmetrical strip holes 903, and the two fixed blocks 707 are slidably installed in the two strip holes 903 respectively. The fixed blocks 707 are eccentrically positioned with respect to the rotating shaft 702.

[0043] In this embodiment, when the strip plate 902 slides away from the stirring shaft 4, the strip hole 903 applies a pushing force to the fixed block 707, causing the two rotating blocks 701 to rotate closer to each other, thereby causing the two L-shaped rods 703 to rotate from a horizontal state to a vertical state; when the strip plate 902 slides close to the stirring shaft 4, the strip hole 903 applies a pulling force to the fixed block 707, causing the two rotating blocks 701 to rotate away from each other, thereby causing the two L-shaped rods 703 to rotate from a vertical state to a horizontal state.

[0044] Specifically, each of the two stirring blades 601 has a through hole 603 on one side where they are in contact with each other. The crossbar 901 is slidably installed in the through hole 603. The outer circumference of the lifting rod 802 has several inclined grooves 803 at equal intervals. The end of the crossbar 901 near the lifting rod 802 is an inclined surface, and the inclined surface of the crossbar 901 is in contact with the inclined inner wall of the inclined groove 803.

[0045] In this embodiment, when the lifting rod 802 slides downward, the inclined inner wall of the inclined groove 803 on the lifting rod 802 will press against the inclined end face of the crossbar 901, causing the crossbar 901, the strip plate 902 and the fixing plate 904 to slide away from the stirring shaft 4.

[0046] Specifically, the pushing component 8 also includes an electric push rod 801. The stirring shaft 4 has a mounting groove 10. The electric push rod 801 is fixedly installed in the mounting groove 10. The lifting rod 802 is fixedly installed on the piston end of the electric push rod 801. The driving component 3 also includes a conductive slip ring 304 and a conductive brush 305. The conductive slip ring 304 is fixedly installed outside the stirring shaft 4. The conductive brush 305 is fixedly installed inside the second bracket 302. The conductive brush 305 is in contact with the conductive slip ring 304. The conductive slip ring 304 is electrically connected to the electric push rod 801.

[0047] In this embodiment, the electric push rod 801 can drive the lifting rod 802 to slide up or down. The conductive slip ring 304 and the conductive brush 305 can supply power to the electric push rod 801. This is a mature existing technology and will not be described in detail here.

[0048] Specifically, the transmission assembly 9 also includes a fixing plate 904 and a spring 905. The fixing plate 904 is fixedly installed on the outside of the crossbar 901. A sliding groove 604 is provided on the side where the two stirring blades 601 are in contact with each other. The fixing plate 904 is slidably installed in the sliding groove 604. The spring 905 is fixedly installed between the fixing plate 904 and the inner wall of one end of the sliding groove 604.

[0049] In this embodiment, when the crossbar 901, strip plate 902, and fixing plate 904 are squeezed away from the stirring shaft 4 by the inclined groove 803, the fixing plate 904 will compress the spring 905. When the crossbar 901 is no longer squeezed by the inclined groove 803, the spring 905 will release and push the crossbar 901, strip plate 902, and fixing plate 904 to reset.

[0050] Working principle: When blending heat transfer oil, base oil is added to blending tank 1, and then motor 303 is started to drive stirring shaft 4 and stirring blade 601 to rotate, starting to stir the base oil and introduce heating medium into heating pipe 5. After the base oil rises to a certain temperature, additives are added, and then electric push rod 801 is started to make lifting rod 802 slide downward. The inclined inner wall of inclined groove 803 on lifting rod 802 will squeeze the inclined end face of cross rod 901, causing cross rod 901, strip plate 902 and fixing plate 904 to slide away from stirring shaft 4. When fixing plate 904 slides, it will compress spring 905. The strip hole 903 on strip plate 902 will apply a pushing force to fixing block 707, causing two rotating blocks 701 to move closer to each other and rotate, thereby causing two L-shaped rods 703 to rotate from horizontal to vertical. Fixing block 707 will rotate in strip hole 903 as rotating block 701 rotates. When fixing block 707 slides into strip hole 903, When the L-shaped rods 703 reach the end of the 903, they can just rotate to a vertical position. At this time, the electric push rod 801 is activated again, causing the lifting rod 802 to slide upward. At this time, the crossbar 901 is no longer squeezed by the inclined groove 803. The spring 905 will be released and push the fixing plate 904, the crossbar 901, and the strip plate 902 to slide closer to the stirring shaft 4. The strip hole 903 on the strip plate 902 will apply a pulling force to the fixing block 707, causing the two rotating blocks 701 to rotate away from each other, thereby causing the two L-shaped rods 703 to rotate from a vertical position to a horizontal position. The fixing block 707 will rotate in the strip hole 903 as the rotating block 701 rotates. When the fixing block 707 slides to the end of the strip hole 903, it can just rotate the two L-shaped rods 703 to a horizontal position. During the rotation of the L-shaped rods 703, the baffle plate 705 will agitate in the oil swirl, greatly increasing the shear force on the additive clusters and improving the uniformity of mixing.
