DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0034] like Figure 1 and Figure 2 As shown, this embodiment discloses a mixing and stirring kettle for lubricating oil processing, comprising a cylinder 1, a cylinder cover assembly 2 is provided on the top of the cylinder 1, a motor 3 is provided in the middle of the upper end of the cylinder cover assembly 2, a rotating shaft assembly 5 located in the cylinder 1 is provided at the output end of the motor 3, a stirring mechanism 4 for mixing raw materials is provided in the middle and upper part of the outer surface of the rotating shaft assembly 5, and a magnetic suction cup 6 used in conjunction with the rotating shaft assembly 5 is rotatably connected to the middle of the bottom wall of the inner cavity of the cylinder 1;

[0035] Specifically, Figure 3 and Figure 4 As shown, the barrel cover assembly 2 includes a top cover 21, a fixing ring 23 is provided in the middle of the inner wall of the side wall of the top cover 21, an annular groove is provided on the outer side of the lower end of the fixing ring 23, and an inner gear ring 25 is provided on the top of the annular groove;

[0036] Specifically, Figure 4 and Figure 5As shown, the rotating shaft assembly 5 includes a turntable 51 rotatably connected to the bottom of the fixed ring 23, a rotating shaft 56 is provided in the middle of the upper end of the turntable 51, and the upper part of the rotating shaft 56 passes through the fixed ring 23 and is connected to the motor 3, a transmission shaft 57 is provided on the outer side of the upper end of the turntable 51, the upper part of the transmission shaft 57 extends into the annular groove and is provided with a spur gear 58, and the spur gear 58 is meshed with the inner gear ring 25, and a control mechanism 52 for rotating by the spur gear 58 is provided at the lower end of the turntable 51, an extraction mechanism 53 is provided in the middle of the lower end of the control mechanism 52, and a pumping mechanism 54 is provided at the lower end of the extraction mechanism 53, and a discharge pipe 55 is provided on the outer surface of the pumping mechanism 54 and the turntable 51, and the discharge pipe 55 is used to transport the raw materials at the bottom of the cylinder 1 to the upper part to avoid the deposition of the raw materials;

[0037] As can be seen from the above, when the motor 3 controls the rotating shaft assembly 5 and the stirring mechanism 4 to rotate and mix the raw materials, the spur gear 58 will rotate due to the engagement with the inner gear ring 25, and then drive the control mechanism 52 to start working through the transmission shaft 57. Thereafter, the control mechanism 52 controls the extraction mechanism 53 to work, and the raw materials at the bottom of the cylinder 1 are continuously extracted through the extraction mechanism 54, and then discharged from the upper part of the cylinder 1 through the discharge pipe 55. In this way, through cyclic extraction and injection, the lubricating oil can form convection in the cylinder 1, reduce the stirring dead angle, and thus improve the mixing efficiency of the device.

[0038] Specifically, Figure 6 and Figure 7 As shown, the control mechanism 52 includes a mounting box 523 fixedly connected to the lower end of the turntable 51, a bidirectional screw 522 is horizontally arranged at the upper part of the inner cavity of the mounting box 523, the lower end of the transmission shaft 57 extends into the mounting box 523 and is provided with a bevel gear set 521 together with the outer surface of the bidirectional screw 522, the left and right parts of the bottom wall of the mounting box 523 are both provided with connecting plates 524, and the right end of the connecting plate 524 close to the discharge pipe 55 is provided with a transmission rod 528, and the transmission rod 528 is connected to the bidirectional screw 52 through a belt. 2 transmission connection, which is a simple belt transmission technology, so it will not be described in detail. A reel 527 is provided at the right end of the transmission rod 528, and four elastic telescopic rods 525 are provided at the left end of the connection plate 524 away from the discharge pipe 55. The left ends of the four elastic telescopic rods 525 are jointly provided with a limit ring 526 sleeved on the outside of the reel 527 for support, so as to improve the structural stability of the reel 527. In addition, since the elastic telescopic rod 525 can be retracted, it will not affect the subsequent departure of the pull rope 532;

[0039] In addition, a pushing mechanism 8 is provided on the outer surface of the bidirectional screw 522, and the pushing mechanism 8 is located between the two connecting plates 524. The middle parts of the front inner wall and the rear inner wall of the installation box 523 are provided with a U-shaped plate 9 used in conjunction with the pushing mechanism 8, and the inner cavity of the U-shaped plate 9 is a U-shaped parallelogram. The ends of the two connecting plates 524 that are away from each other are provided with a blocking mechanism 7 for intermittent work, that is, the two blocking mechanisms 7 work in batches.

[0040] Specifically, Figure 5 As shown, the extraction mechanism 53 includes a connecting tube 531 fixedly connected to the bottom of the installation box 523, and the connecting tube 531 is connected to the installation box 523, the inner cavity of the connecting tube 531 is provided with a piston head 534 for pushing the raw material, and a spring 533 is provided between the upper end of the piston head 534 and the inner cavity top wall of the connecting tube 531, and a pull rope 532 is provided in the middle of the upper end of the piston head 534, and a part of the pull rope 532 away from the piston head 534 passes through the connecting tube 531 and the installation box 523 and is wound on the reel 527;

[0041] As can be seen from the above, the transmission shaft 57 first controls the rotation of the bidirectional screw 522 through the bevel gear set 521, and then the bidirectional screw 522 controls the rotation of the reel 527 through the belt to wind the pull rope 532, pull the piston head 534 upward, and extract the raw material at the bottom of the cylinder 1;

[0042] During this process, the bidirectional screw 522 will also control the pushing mechanism 8 to move left and right to push away the pull rope 532 wrapped around the reel 527. When the pushing mechanism 8 moves, it will control one of the blocking mechanisms 7 to work, so that the piston head 534 can quickly push the raw materials in the connecting pipe 531 into the discharge pipe 55 under the action of spring 1 533.

[0043] Specifically, Figure 5 As shown, the extraction mechanism 54 includes a sealing top plate 543 fixedly connected to the bottom of the connecting pipe 531, the discharge pipe 55 is connected to the sealing top plate 543, the bottom of the sealing top plate 543 is provided with a sealing bottom plate 541 with a magnetic component inside, and the sealing bottom plate 541 is magnetically attracted to the magnetic suction cup 6, the outer surfaces of the sealing top plate 543 and the sealing bottom plate 541 are jointly provided with a connecting groove 542, and the connecting groove 542 is connected to the inner cavity of the connecting pipe 531 and the discharge pipe 55, and the upper end of the sealing top plate 543 is provided with two plug-in grooves connected to the connecting groove 542, and the two plug-in grooves are respectively located on the left and right sides of the connecting pipe 531;

[0044] The magnetic chuck 6 can not only support the rotating shaft assembly 5 and improve the structural stability of the rotating shaft assembly 5, but also can separate the sealing bottom plate 541 and the connecting groove 542 by magnetic attraction when the rotating shaft assembly 5 leaves, so that the residual raw materials in the discharge pipe 55 and the connecting pipe 531 can flow out through the gap between the sealing bottom plate 541 and the sealing top plate 543, thereby reducing omissions and avoiding damage to the ingredient ratio during the next mixing;

[0045] Specifically, Figure 8 As shown, the pushing mechanism 8 includes a moving box 81 and a pushing plate 84, and the bottom of the pushing plate 84 is an inwardly concave arc structure, and the front and rear ends of the pushing plate 84 are provided with two elastic telescopic rods 85, and the two elastic telescopic rods 85 are respectively slidably connected in the inner cavity of the Chinese-shaped plate 9 on the same side, and a plug-in plate 83 is provided in the middle of the upper end of the pushing plate 84. The upper part of the moving box 81 is sleeved on the outer side of the bidirectional screw 522 and is threadedly connected to the bidirectional screw 522, and the lower part of the moving box 81 is sleeved on the outer side of the plug-in plate 83 and is slidably connected to the plug-in plate 83;

[0046] Furthermore, the distance between the bottom wall of the push plate 84 and the outer surface of the drum 527 is equal to 1.5 times the diameter of the pull rope 532, so as to prevent the connection node between the pull rope 532 and the drum 527 from affecting the normal movement of the push mechanism 8;

[0047] As can be seen from the above, when the bidirectional screw 522 rotates to control the movement of the moving box 81, the moving box 81 will drive the pushing plate 84 to move through the plug-in plate 83, pushing the pull rope 532 from the gap between the right end of the drum 527 and the connecting plate 524, and then the pushing plate 84 continues to move to the right, and the elastic telescopic rod 85 is used to slide in the U-shaped plate 9 to move the pushing plate 84 upward, so as to avoid the pushing plate 84 pushing the pull rope 532 to the left side of the drum 527 on the way back, causing the pull rope 532 to accumulate on the left part of the drum 527, affecting the subsequent left and right movement of the pushing plate 84 and the normal operation of the extraction mechanism 53. When the moving box 81 returns, it will return to its initial position under the guidance of the inner wall of the U-shaped plate 9.

[0048] Specifically, Figure 8 and Fig. 9As shown, the blocking mechanism 7 includes an L-shaped tube 71 fixedly connected to the connecting plate 524 and a sealing plate 75 slidably connected in the plug-in groove. The lower left and right ends of the moving box 81 are both provided with piston rods 82. A part of the piston rod 82 away from the moving box 81 passes through the side wall of the connecting plate 524 and extends into the L-shaped tube 71 on the same side. The inner cavity of the L-shaped tube 71 is filled with hydraulic oil. The lower end of the L-shaped tube 71 is provided with a storage cylinder 72. A moving groove 76 is opened in the middle part of the upper end of the sealing plate 75. The moving groove 76 and the inner side of the storage cylinder 72 are jointly provided with an I-shaped rod 74. A spring 2 73 is jointly provided between the top of the I-shaped rod 74 and the bottom wall of the storage cylinder 72. A spring 3 77 is jointly provided between the lower end of the I-shaped rod 74 and the bottom wall of the moving groove 76 to provide a buffer space to avoid jamming, and the raw material in the connecting tube 531 returns to the bottom of the cylinder body 1 through the connecting groove 542.

[0049] Furthermore, when the connection node between the pull rope 532 and the drum 527 and the push plate 84 are located in the same vertical plane, the sealing plate 75 just completes the blocking of the communication groove 542;

[0050] From the above, it can be seen that when the pushing mechanism 8 moves left and right, it will also push the hydraulic oil in the L-shaped tube 71 into the storage cylinder 72 through the piston rod 82, forcing the I-shaped rod 74 and the sealing plate 75 to move downward to block the connecting groove 542. In addition, since the positions of the two blocking mechanisms 7 are symmetrical to each other, when one of the sealing plates 75 blocks the connecting path between the connecting tube 531 and the cylinder body 1, the other sealing plate 75 will open the connecting path between the discharge pipe 55 and the connecting pipe 531, and vice versa, thereby preventing the raw material in the connecting tube 531 from returning to the bottom of the cylinder body 1 through the connecting groove 542.

[0051] Therefore, the specific implementation of this embodiment is:

[0052] When the motor 3 controls the rotating shaft assembly 5 and the stirring mechanism 4 to rotate and stir the raw materials, the spur gear 58 will rotate due to meshing with the inner gear ring 25, and then control the rotation of the bidirectional screw 522 through the transmission shaft 57 and the bevel gear set 521. The bidirectional screw 522 then controls the rotation of the drum 527 through the belt to wind the pull rope 532, pull the piston head 534 upward, and extract the raw materials at the bottom of the cylinder 1. In this process, the bidirectional screw 522 will also control the pushing mechanism 8 to move right, and push the pull rope 532 down from the gap between the right end of the drum 527 and the connecting plate 524;

[0053] At the same time, the pushing mechanism 8 will also control the two blocking mechanisms 7 to work in opposite states through the piston rod 82, pushing the hydraulic oil in the L-shaped tube 71 on the right side of the reel 527 into the storage tube 72, forcing the I-shaped rod 74 and the sealing plate 75 on the same side to move downward to block the connecting groove 542, while releasing the space in the L-shaped tube 71 on the left side of the reel 527, so that the hydraulic oil in the storage tube 72 can return to the L-shaped tube 71 under the action of the spring 2 73 and the I-shaped rod 74, so that the sealing plate 75 on the same side moves upward, and the blocking of the connecting path between the discharge pipe 55 and the connecting pipe 531 is released, so that the piston head 534 can quickly push the raw material in the connecting pipe 531 into the discharge pipe 55 under the action of the spring 1 533, and finally discharge it back into the cylinder 1 from the upper part of the cylinder 1. In this way, through cyclic extraction and injection, the lubricating oil can form convection in the cylinder 1, reducing the mixing dead angle, thereby improving the mixing efficiency of the device. Embodiment 2

[0054] This embodiment further improves the stirring mechanism 4 on the basis of the first embodiment, so as to expand the stirring area, increase the way of mixing raw materials, and thus improve the mixing efficiency of raw materials. Figure 2 and Figure 3 As shown, a wavy annular groove 22 is provided on the inner top wall of the top cover 21, and three ventilation grooves 24 are provided on the top wall of the wavy annular groove 22, which vertically penetrate the side wall of the top cover 21, and the three ventilation grooves 24 are distributed in a circular array, and the ventilation grooves 24 are distributed on the path of the slide pipe 43 moving outward. A filter ring that does not contact the motor 3 is also provided on the upper end of the top cover 21 to prevent dust in the air from entering the raw material through the ventilation groove 24 and the slide pipe 43;

[0055] Specifically, Fig.10 As shown, the stirring mechanism 4 includes a fixed disk 41 sleeved on the outside of the connecting pipe 531 and two I-shaped rods 74, the I-shaped rods 74 are slidably connected to the fixed disk 41, and three rotating plates 42 are evenly arranged on the outer surface of the fixed disk 41, and an air storage box 45 is arranged on the outer side of the rotating plate 42, and a slide tube 43 connected to the air storage box 45 is arranged on the upper end of the air storage box 45, and the top of the slide tube 43 is slidably connected in the wavy annular groove 22, a one-way valve 1 is arranged on the inner side of the slide tube 43, and a one-way valve 2 44 is arranged on the bottom of a part of the air storage box 45 away from the fixed disk 41, which is connected to the outside;

[0056] From the above, it can be seen that when the rotating shaft assembly 5 controls the stirring mechanism 4 to stir the raw materials, the air storage box 45 will also continuously expand and contract due to the sliding tube 43 sliding in the wavy ring groove 22, thereby changing the stirring area and improving the stirring effect. In addition, when the air storage box 45 is extended, the air storage box 45 will draw air from the outside through the sliding tube 43. When the air storage box 45 contracts, the air in the air storage box 45 will be discharged into the raw materials through the one-way valve 44 to form bubbles. The bubbles will drive the liquid to flow during the process of rising in the liquid, further enhancing the mixing effect, thereby achieving the effect of pulse mixing.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
