DETAILED DESCRIPTION

[0032] like Figure 1-Figure 3 As shown, a stirring device for oil blending process includes a cylinder 1, two funnels are fixedly installed on the top end surface of the cylinder 1, and the funnels are communicated with the cylinder 1, so as to add base oil and additives into the cylinder 1, a rotating shaft 6 is arranged in the cylinder 1, and the rotating shaft 6 is coaxially arranged with the cylinder 1, and a spiral stirring plate 4 is arranged on the periphery of the rotating shaft 6, and at least one group of stirring plates 4 is arranged, and a plurality of support rods 7 are fixedly arranged on the outer circumferential surface of the rotating shaft 6, and a stirring rod 8 is fixedly installed on the end of the support rod 7 away from the rotating shaft 6, and the stirring rod 8 is fixed to the stirring plate 4. Through this structure, when the rotating shaft 6 drives the stirring rod 8 and the stirring plate 4 to rotate, the oil in the cylinder 1 can be stirred, so that the base oil and the additive are fully mixed.

[0033] In actual use, in order to facilitate the understanding of the degree of mixing of raw materials, the present scheme is provided with a plurality of collecting boxes 3 on the top surface of the stirring plate 4, and the plurality of collecting boxes 3 are distributed in a spiral ascending manner along the top surface of the stirring plate 4, which is beneficial for collecting raw materials at various levels in the cylinder 1, and a limiting plate 9 is provided on the outer side of the stirring plate 4 in the cylinder 1, and the limiting plate 9 is arranged along the vertical direction, and the collecting box 3 located at the bottom end of the stirring plate 4 can cooperate with the limiting plate 9 through a limiting assembly. Specifically, when the collecting box 3 and the limiting plate 9 are connected through the limiting assembly, the stirring plate 4 can prompt the collecting box 3 to move upward along the limiting plate 9 during the rotation process, which is beneficial for the staff to take out the collecting box 3.

[0034] like Figure 2-Figure 10As shown, the limiting assembly includes a limiting block 14 which is arranged on the outer side of the collecting box 3 and elastically connected to the collecting box 3, and a horizontal introduction groove 901 and a vertical limiting groove 903 are provided on the side of the limiting plate 9 close to the stirring plate 4. The introduction groove 901 is located at the bottom end of the limiting groove 903 and is connected to the limiting groove 903. When the limiting block 14 is in a pop-up state, the stirring plate 4 drives the collecting box 3 to move to the limiting plate 9, and the limiting block 14 can enter into the limiting groove 903 along the introduction groove 901. The setting of the limiting groove 903 is conducive to preventing the collecting box 3 from continuing to rotate with the stirring plate 4, so that the collecting box 3 can be squeezed upward by the stirring plate 4.

[0035] In order for the collecting box 3 to collect the raw materials in the cylinder 1, a baffle 10 is hingedly connected to one end of the collecting box 3, and a baffle 15 is arranged on the inner side of the baffle 10 and near the top. The baffle 15 can rotate relative to the collecting box 3, and the baffle 15 is elastically connected to the collecting box 3.

[0036] Furthermore, a fixing plate 18 is provided at one end of the baffle rod 15 away from the baffle plate 10, and a positioning block 19 is elastically mounted on the side of the fixing plate 18 close to the baffle rod 15, and a positioning groove matching with the positioning block 19 is provided on the end face of the baffle rod 15. In the initial state, one end of the positioning block 19 is inserted into the positioning groove, thereby limiting the baffle rod 15 so that the baffle rod 15 is located on one side of the baffle plate 10, thereby preventing the baffle plate 10 from rotating.

[0037] A boss 301 is fixedly provided on the outer side of the top of the collection box 3, and a magnetic block 302 is elastically provided on the outer side of the boss 301. A traction rope 17 is fixedly provided between the magnetic block 302 and the positioning block 19. The traction rope 17 passes through the collection box 3 and the boss 301 and slides with them. Figure 3 As shown, a plurality of magnetic plates 902 are fixedly embedded on one side surface of the limit plate 9 close to the stirring plate 4, and the plurality of magnetic plates 902 correspond one by one to the plurality of bosses 301 in the horizontal direction, and the opposite side of the magnetic plate 902 and the magnetic block 302 has different magnetic poles. When the stirring plate 4 drives the boss 301 to move to one side of the magnetic plate 902, the suction force between the magnetic plate 902 and the magnetic block 302 can tighten the traction rope 17, thereby pulling one end of the positioning block 19 out of the positioning groove. At this time, the baffle rod 15 can be deflected and staggered with the baffle plate 10, which is conducive to the raw materials in the cylinder 1 to enter the collecting box 3.

[0038] A plug-in block 20 is elastically mounted on the collection box 3 at the bottom end of the stirring plate 4. The plug-in block 20 is located at the top surface of the limit block 14, and a slot matching the plug-in block 20 is opened on the top surface of the limit block 14. In the initial state, one end of the plug-in block 20 is inserted into the slot to limit the limit block 14. A pull rope 16 is fixedly arranged between the plug-in block 20 and the magnetic block 302. The pull rope 16 passes through the collection box 3 and the boss 301 and slides with it.

[0039] In actual use, in order to lock the collection box 3 on the top surface of the stirring plate 4, the present invention provides a spiral guide groove 401 on the top surface of the stirring plate 4, and the guide groove 401 can be located at the midline position of the stirring plate 4. A connecting block 12 is fixedly provided on the bottom end surface of the collection box 3, and the connecting block 12 is slidably provided in the guide groove 401, and a card block 11 is elastically installed at the bottom end of the connecting block 12. Figure 5 As shown, both sides of the bottom end of the card block 11 are set as inclined surfaces 1101, and the inner bottom surface of the guide groove 401 is provided with a card slot matching with the card block 11. In the initial state, the card block 11 is located in the card slot, and a part of the inclined surface 1101 on the card block 11 is located on the outside of the card slot. Through this structure, only when the pressure between the inclined surface 1101 on the card block 11 and the side edge of the card slot is large enough, the card block 11 can be moved out of the card slot, so that the collection box 3 can move relative to the stirring plate 4.

[0040] During actual use, the base oil and additives are added into the barrel 1 through the hopper 102, and the rotating shaft 6 can drive the stirring rod 8 and the stirring plate 4 to rotate, thereby promoting the mutual fusion of the base oil and the additives. When the raw material needs to be sampled, the limiting plate 9 can be driven to move in the direction close to the stirring plate 4, so that the stirring plate 4 can be in a state of contact with the limiting plate 9 during the rotation process. When the collecting box 3 at the bottom end of the stirring plate 4 moves to the limiting plate 9 so that the magnetic block 302 on the boss 301 is aligned with the magnetic plate 902 at the bottom end of the limiting plate 9, the suction force of the magnetic plate 902 on the magnetic block 302 can pull the traction rope 17 and the pull rope 16. Specifically, when the magnetic block 302 and the magnetic plate 902 are in a relatively aligned state, the limiting block 14 has passed the limiting groove 903. Therefore, when the plug-in block 20 is pulled out by the pull rope 16, the limiting Although the block 14 can pop out, one end of the limit block 14 will not be inserted into the limit groove 903, but will be against the side of the limit plate 9. In addition, the positioning block 19 can be pulled by the traction rope 17, so that one end of the positioning block 19 is moved out of the positioning groove. At this time, the blocking rod 15 can be rotated to a state staggered with the baffle 10, so that the baffle 10 can rotate inwardly relative to the collecting box 3, so that the opening on one side of the collecting box 3 is in an open state. At this time, the raw materials in the cylinder 1 can enter the collecting box 3. When the collecting box 3 at the bottom layer of the stirring plate 4 passes over the limit plate 9 for the first time, the multiple collecting boxes 3 above it will also pass through the limit plate 9 one after another. In this process, the suction force between the magnetic block 302 and the magnetic plate 902 can cause the baffle 10 at one end of the collecting box 3 to be in an inclined state, so that the raw materials at different levels in the cylinder 1 can be sampled through each collecting box 3;

[0041] When the collecting box 3 at the bottom end of the stirring plate 4 reaches the limiting plate 9 for the second time, since the limiting block 14 at the collecting box 3 is in a pop-up state, the limiting block 14 can slide along the introduction slot 901 to the limiting slot 903, and the limiting slot 903 restricts the limiting block 14, so that the collecting box 3 cannot continue to rotate with the stirring plate 4. At this time, when the stirring plate 4 continues to rotate, the pressure between the card block 11 at the collecting box 3 and the side edge of the card slot increases, so that the card block 11 can move out of the card slot, so that the collecting box 3 can slide relative to the stirring plate 4, and the pressure of the stirring plate 4 on the collecting box 3 can drive the collecting box 3 to move along the limiting plate 9 one by one. When the stirring plate 4 is rotated, the two collecting boxes 3 can be driven to move upward simultaneously. In summary, during the rotation of the stirring plate 4, multiple collecting boxes 3 can be in a state of mutual adhesion, and as the stirring plate 4 rotates, multiple collecting boxes 3 can be driven to move upward to the top position of the cylinder 1, which is convenient for the staff to take them out.

[0042] To sum up, this device can, through the stirring plate 4, on the one hand, stir the raw materials in the cylinder 1 so that the base oil and the additive are fully mixed, and on the other hand, can drive the multiple collecting boxes 3 on its surface to move upward to the top position of the cylinder 1, so as to facilitate the staff to take the collecting box 3. The set collecting box 3 is conducive to sampling the raw materials of each layer in the cylinder 1, so as to understand the mixing situation of the raw materials in the cylinder 1 at this time, which is conducive to providing a basis for the mixing time.

[0043] like Figure 1-Figure 3 As shown, both ends of the rotating shaft 6 are rotatably matched with the cylinder 1, and in order to drive the rotating shaft 6 to rotate, a motor is arranged at the outer bottom end of the cylinder 1, and the output shaft of the motor and one end of the rotating shaft 6 passing through the cylinder 1 are fixedly provided with pulleys, and a belt 5 is sleeved between the two pulleys. This structure is conducive to driving the rotating shaft 6 to rotate.

[0044] A rectangular groove for accommodating the limit plate 9 is opened on the inner wall of the cylinder 1. In order to drive the limit plate 9 to move, a telescopic unit 2 is fixedly installed on the outer side of the cylinder 1. The telescopic unit 2 can be a cylinder or a hydraulic rod, etc. The telescopic end of the telescopic unit 2 passes through the cylinder 1 and slides with it, and the telescopic end of the telescopic unit 2 is fixedly connected to the limit plate 9, thereby driving the limit plate 9 to move relative to the cylinder 1.

[0045] In actual use, the top of the cylinder 1 can be an open structure and sealed by a disc. Specifically, the disc is fixed to the cylinder 1 by bolts, and the hopper 102 can be installed on the disc. A through groove is opened on the disc. The through groove is arranged opposite to the limit plate 9 in the vertical direction, and a cover plate 103 is hinged at the through groove. The through groove can be sealed by the cover plate 103. When the collection box 3 needs to be taken out, the cover plate 103 can be opened.

[0046] A flow guide pipe 101 is fixedly installed at the bottom end of the cylinder 1 . The flow guide pipe 101 is connected to the cylinder 1 , and a valve is arranged on the flow guide pipe 101 .

[0047] Reference Figure 5 , Fig.11 As shown, a protrusion 13 is fixedly provided on the top end face of the clamping block 11, and a groove for slidingly cooperating with the protrusion 13 is opened on the connecting block 12. Specifically, the cross-sections of the groove and the protrusion 13 are both set to be T-shaped, and a first spring is fixedly provided between the inner end face of the groove and the protrusion 13.

[0048] In actual use, in order to improve the stability of the connection between the connecting block 12 and the stirring plate 4, the present solution can be provided with a pressure block 1201 on both sides of the connecting block 12 through spring elasticity, and the cross-section of the guide groove 401 can be set to a T-shape, so that the pressure block 1201 is slidably set in the guide groove 401. Through this structure, the connection block 12 can be prevented from moving in the vertical direction relative to the stirring plate 4. For this method, the two ends of the guide groove 401 need to extend to the end surface of the stirring plate 4, which is convenient for taking out the collection box 3. Of course, the end of the pressure block 1201 away from the connecting block 12 can be a curved structure, which is convenient for the staff to directly take out the collection box 3. In this embodiment, the two ends of the guide groove 401 may not extend to the end surface of the stirring plate 4.

[0051] The section of the pull rope 16 and the traction rope 17 extending to the magnetic block 302 can be combined into one strand, thereby facilitating the magnetic block 302 to pull the pull rope 16 and the traction rope 17 synchronously.

[0052] Reference Figure 7 As shown, a circular shaft 1001 is fixedly provided on both sides of the baffle 10 and near the bottom end, and a mounting hole is opened on the side wall of the collecting box 3, so that the circular shaft 1001 passes through the mounting hole and is rotatably connected to the collecting box 3, and a second coil spring is sleeved on the outside of the circular shaft 1001, and the two ends of the second coil spring are respectively fixedly connected to the inner wall of the mounting hole and the outer wall of the circular shaft 1001.
