[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Reference Figure 1-11 , an edible oil vacuum smelting device, comprising a smelting tank 1, a ring circulation line mechanism 2, a control mechanism 3, an exhaust mechanism 4 and a support mechanism 5, the ring circulation line mechanism 2 is used to drive the smelting tank 1 to perform a circular motion, the exhaust mechanism 4 is used to extract the air in the smelting tank 1, and a stirring mechanism 6 is arranged in the smelting tank 1;

[0041] The control mechanism 3 includes a circular shaft 301, a control ring 302 is fixedly sleeved on the outer side of the circular shaft 301, two grooves are provided on the outer side of the control ring 302, a baffle 311 is provided on the inner wall of one side of the groove, a push rod 101 is fixedly installed on the top of the smelting pot 1, and the push rod 101 is adapted to the groove, a plurality of support frames 307 are fixedly installed on the top of the control ring 302, and the bottoms of the two support frames 307 located on the same side are fixedly installed with the same support plate 303, a mounting plate 304 is vertically slidably installed on the top of the support plate 303, a motor 305 is fixedly installed on the bottom of the mounting plate 304, a square rod 306 is fixedly installed on the output shaft of the motor 305, a ring edge mechanism 310 is fixedly installed on the top of the support mechanism 5, and the top of the mounting plate 304 is slidably connected to the bottom of the ring edge mechanism 310.

[0042] It should be noted that, in the present invention, multiple smelting tanks 1 can be provided, but the number of smelting tanks 1 passing through the semicircular section of the annular plate 502 at the same time can only be two. The smelting efficiency of the entire device can be improved by setting a reasonable number of smelting tanks 1.

[0043] In this embodiment, the supporting mechanism 5 includes a plurality of side plates 501, on which the same annular plate 502 is fixedly mounted, and a hanging plate 503 is fixedly mounted on the top of two of the plurality of side plates 501, and the hanging plate 503 is fixedly connected to the ring edge mechanism 310, and the ring edge mechanism 310 includes a lower ring edge and two upper ring edges, and the upper ring edge and the lower ring edge are connected by an inclined surface.

[0044] It should be noted that the smelting pot 1 drives the control ring 302 to rotate, thereby driving the support plate 303, the mounting plate 304 and the motor 305 to rotate synchronously. When the mounting plate 304 moves along the upper ring edge of the ring edge mechanism 310 to the lower ring edge, the mounting plate 304 moves downward under the restriction of the ring edge mechanism 310, thereby driving the motor 305 and the square rod 306 to move downward together, controlling the start of the stirring mechanism 6. When the mounting plate 304 moves along the lower ring edge of the ring edge mechanism 310 to another upper ring edge, the mounting plate 304 gradually rises under the action of the support spring 309, stopping the stirring mechanism 6.

[0045] In this embodiment, the vacuum mechanism 4 includes a vacuum pump 402, a track plate 401 and a rotating cylinder 403. A circular hole is opened on the track plate 401, and the circular shaft 301 is rotatably installed in the circular hole. A vertical plate 203 is arranged on the annular circulation line mechanism 2. The vacuum pump 402 and the track plate 401 are fixedly connected to the vertical plate 203. The rotating cylinder 403 is fixedly connected to the circular shaft 301 through a fixed plate 404. Two curved pipes 405 are connected to the top of the rotating cylinder 403. The input end of the vacuum pump 402 is rotatably sealed and connected to the bottom of the rotating cylinder 403. An exhaust pipe 406 is provided on the outer side of the curved pipe 405. A guide rod 407 is fixedly installed on the outer side of the exhaust pipe 406. A track groove 408 is opened at the bottom of the track plate 401. Two guide rods 407 are slidably installed in the track groove 408.

[0046] It should be noted that the track groove 408 is composed of arcs with different radii at both ends, the two arcs are connected, and the entire track groove 408 is symmetrically arranged. The guide rod 407 moves along the track groove 408 to realize the extension and retraction function of the exhaust pipe 406.

[0047] Furthermore, when the smelting pot 1 enters the semicircular section of the annular plate 502, the smelting pot 1 drives the control ring 302 to rotate through the push rod 101. At this time, the guide rod 407 moves from the small radius arc on the track groove 408 to the large radius arc, thereby realizing the function of extending the exhaust pipe 406 to connect with the exhaust pipe 102. When the annular plate 502 rotates a certain angle, the guide rod 407 returns from the large radius arc to the small radius arc, thereby realizing the function of retracting the exhaust pipe 406 and separating it from the exhaust pipe 102.

[0048] In this embodiment, the outside of the smelting tank 1 is connected to the exhaust pipe 102, one end of the exhaust pipe 102 is provided with a connecting pipe, one end of the exhaust pipe 406 is provided with a sleeve 409, the sleeve 409 is adapted to the exhaust pipe 102, one end of the sleeve 409 is provided with a sealing ring 410, the exhaust pipe 406 and the connecting pipe are provided with a one-way valve, the two one-way valves are provided with the same opening and closing mechanism 7, the valve plates 704 of the one-way valves located in the connecting pipe and the exhaust pipe 406 are respectively fixedly mounted with a short rack 702 and a long rack 701, a gear 703 is rotatably installed in the connecting pipe, and the long rack 701 and the short rack 702 are both adapted to the gear 703.

[0049] It should be noted that after the smelting tank 1 is evacuated and the vacuum pump 402 is evacuating air, the smelting tank 1 and the rotating cylinder 403 are in a negative pressure state, and it is necessary to prevent outside air from entering the smelting tank 1 and the rotating cylinder 403. Therefore, the flow direction of the one-way valve on the connecting pipe and the exhaust pipe 406 is that the connecting pipe and the exhaust pipe 406 flow to the outside.

[0050] Furthermore, when the exhaust pipe 406 and the connecting pipe are close to each other, the long rack 701 drives the gear 703 to rotate, thereby driving the long rack 701 and the short rack 702 to move toward the side close to each other, thereby opening the two one-way valves and realizing the automatic opening and closing function of the connecting pipe and the exhaust pipe 406.

[0051] In this embodiment, the stirring mechanism 6 includes a stirring shaft 601, and a plurality of storage grooves are opened on the outer side of the stirring shaft 601. A stirring blade 602 is rotatably installed at the top of the storage groove. A round-mouth long groove 611 is opened at the bottom end of the stirring shaft 601. A plurality of lifting plates 603 are slidably installed in the round-mouth long groove 611. The same connecting plate 604 is fixedly connected between two adjacent lifting plates 603. A paddle plate 605 is fixedly installed on the top of the stirring blade 602. A connecting hole is connected between the storage groove and the round-mouth long groove 611. The paddle plate 605 passes through the corresponding connecting hole and movably abuts against the bottom of the lifting plate 603.

[0052] In this embodiment, a rotating shaft 606 is fixedly installed on the top of the stirring shaft 601, a rotating hole is opened on the top of the smelting tank 1, and the rotating shaft 606 is rotatably installed in the rotating hole. The rotating shaft 606 and the stirring shaft 601 are opened with the same square groove 610, and a push plate 607 is slidably installed in the square groove 610. An insert plate 608 is fixedly installed at the bottom of the push plate 607. One side of the insert plate 608 extends into the round-mouth long groove 611 and is fixedly connected to the top of the uppermost lifting plate 603. A plurality of return springs 609 are fixedly installed between the push plate 607 and the bottom inner wall of the square groove 610, and the square groove 610 is adapted to the square rod 306.

[0053] It should be noted that, as described above, the motor 305 and the square rod 306 are driven downward by the cooperation of the mounting plate 304 and the ring edge mechanism 310. After the square rod 306 is fully inserted into the square groove 610, the motor 305 is started, thereby driving the stirring shaft 601 to rotate to realize the stirring function, and the square rod 306 drives the multiple stirring blades 602 to rotate upward through the cooperation of the lifting plate 603 and the paddle plate 605, thereby extending out of the stirring shaft 601. At this time, the reset spring 609 is in a compressed state.

[0054] Furthermore, when the square rod 306 moves upward and leaves the square groove 610, the stirring blade 602 rotates downward under the action of the return spring 609 and its own gravity, and is re-stored in the storage groove to facilitate the subsequent crude oil precipitation. The stirring blade 602 will hinder the precipitation of the crude oil, and impurities are easily accumulated on the stirring blade 602. Long-term use will not only damage the stirring blade 602, but also affect the purity of crude oil refining.

[0055] In this embodiment, an electric meter box 103 is provided outside the smelting pot 1 , and a heating coil 104 is fixedly mounted on the inner wall of the smelting pot 1 . The heating coil 104 is wound outside the stirring mechanism 6 , and the electric meter box 103 is electrically connected to the heating coil 104 .

[0056] It should be noted that the heating coil 104 is powered by the electric meter box 103, and the heating coil 104 heats the crude oil in the smelting tank 1. The crude oil usually has a high viscosity at room temperature. Heating can reduce its viscosity, making it easier to perform operations such as stirring, separation and filtering in the subsequent refining process. Heating can promote some chemical reactions, such as decomposing impurities, removing free fatty acids, etc., thereby improving the quality of the crude oil. Heating the crude oil can promote the adsorption and action of the decolorizer, improve the decolorization effect, and make the refined oil more transparent and pure. Heating can help vaporize the water in the crude oil, facilitate the subsequent dehydration operation, and reduce the water content in the crude oil.

[0057] In this embodiment, a storage box 105 is fixedly installed on the top of the smelting tank 1, a filling pipe is provided on one side of the storage box 105, a guide pipe 106 is provided at the bottom of the storage box 105, and the bottom end of the guide pipe 106 extends into the smelting tank 1, and the smelting tank 1 includes an oil injection pipe 107 and a discharge pipe 108. The oil injection pipe 107, the discharge pipe 108 and the guide pipe 106 are all provided with control valves, and multiple control valves respectively control the switches of the oil injection pipe 107, the discharge pipe 108 and the guide pipe 106, and the timing of the addition of hot alkaline water is controlled by the guide pipe 106, and the function of discharging soap nuts is realized by the discharge pipe 108.

[0058] In this embodiment, the annular circulation line mechanism 2 includes an annular guide rail 201 and a driving chain 202. A notched ring plate 110 is fixedly installed on the outer side of the smelting tank 1, and a sliding seat 111 is fixedly installed on the bottom of the notched ring plate 110. Four rollers are rotatably installed on the sliding seat 111. Guide rail grooves are provided on both the inner and outer sides of the annular guide rail 201, and the rollers are rollingly connected in the corresponding guide rail grooves. A hanging plate 112 is fixedly installed on one side of the sliding seat 111, and the hanging plate 112 is fixedly connected to the driving chain 202. An external plate 109 is fixedly installed on the outer side of the smelting tank 1, and two rollers are rotatably installed on the external plate 109. An annular groove is provided on the outer side of the annular plate 502, and the rollers are rollingly connected in the annular groove.

[0059] It should be noted that the cooperation between the annular guide rail 201 and the sliding seat 111 , and the cooperation between the external plate 109 and the annular plate 502 , play a role in supporting and guiding the movement of the smelting pot 1 .

[0060] In this embodiment, two round rods 308 are vertically slidably installed on the top of the support plate 303, and the top of the round rods 308 is fixedly connected to the mounting plate 304. Two support springs 309 are fixedly connected between the mounting plate 304 and the support plate 303. The support springs 309 are wound around the outer sides of the corresponding round rods 308 to support the mounting plate 304.

[0061] The operating principle of the present invention is described as follows: crude oil is injected into the smelting tank 1 through the oil injection pipe 107, and the heating coil 104 is started through the electric meter box 103. After heating for a period of time, the volatile impurities in the crude oil are fully volatilized, and the driving chain 202 is started. The driving chain 202 drives the smelting tank 1 to move counterclockwise along the annular plate 502. When the smelting tank 1 moves to the semicircular section of the annular plate 502, the push rod 101 on the smelting tank 1 is stuck in the groove on the control ring 302, thereby driving the control ring 302, the circular shaft 301 and the top ring to rotate together. When the mounting plate 304 moves along the upper ring edge of the ring edge mechanism 310, the driving chain 202 drives the smelting tank 1 to move counterclockwise along the annular plate 502. When the screw moves to the lower ring edge, the mounting plate 304 moves downward under the restriction of the ring edge mechanism 310, so that the square rod 306 is inserted into the square groove 610, thereby driving the push plate 607 and the plurality of lifting plates 603 to move downward, and the lifting plate 603 drives the plurality of stirring blades 602 to rotate upward by cooperating with the dial plate 605, and the motor 305 is started, and the motor 305 drives the stirring shaft 601 and the plurality of stirring blades 602 to rotate, accelerating the volatilization of volatile impurities in the crude oil, and the top ring drives the rotating drum to rotate synchronously through the fixing plate 404, and the guide rod 407 on the exhaust pipe 406 moves along the track groove 408, and the exhaust pipe is driven by the reaction force. 406 moves toward the side close to the exhaust pipe 102 until the exhaust pipe 406 is connected and communicated with the exhaust pipe 102, and the volatile impurity gas, water vapor and air in the smelting tank 1 are extracted out of the smelting tank 1 through the vacuum pump 402, so that a vacuum environment is formed in the smelting tank 1. After continuing to move for a period of time, the guide rod 407 continues to move along the track groove 408 to drive the exhaust pipe 406 to separate from the exhaust pipe 102, and the exhaust pipe 102 is closed by the one-way valve. The hot alkaline water in the storage box 105 enters the smelting tank 1 through the guide pipe 106, and is fully contacted with the crude oil and reacts under the action of the stirring mechanism 6. When the smelting pot 1 moves to the semicircular section away from the annular plate 502, the mounting plate 304 moves along the lower ring edge of the ring edge mechanism 310 to the upper ring edge, and the mounting plate 304 gradually rises under the action of the support spring 309, so that the square rod 306 is separated from the square groove 610. Under the action of the reset spring 609 and gravity, the stirring blade 602 rotates downward and is retracted into the stirring shaft 601. Since the smelting pot 1 moves slowly, in the subsequent movement, the reacted crude oil in the smelting pot 1 gradually precipitates and stratifies to form soap nuts and essential oils. The soap nuts are discharged through the discharge pipe 108 to realize the vacuum smelting function of the crude oil.

[0062] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
