Description

Technical Field

[0001] This utility model relates to the technical field of flame retardant lubricant processing equipment, and more specifically, to an automatic proportioning device for environmentally friendly flame retardant raw materials. Background Technology

[0002] Flame retardant lubricant is a lubricating medium that reduces the frictional resistance of friction pairs and slows down their wear. Flame retardant lubricant can also cool, clean and prevent contamination of friction pairs. In the production process of flame retardant lubricant, it is necessary to make proportions of raw materials, so an automatic lubricant raw material proportioning device is used. The raw materials include powdered raw materials and liquid raw materials.

[0003] In existing technologies, metering pumps are generally used when adding liquid raw materials. Metering pumps can add a specified amount of liquid raw materials into the mixing vessel and achieve automatic proportioning. However, there are some problems in its use. When adding liquid raw materials, the metering pump can add the liquid raw materials quickly at the beginning. When the liquid raw materials are about to reach the set value, the flow rate of the metering pump needs to be reduced. Moreover, the closer to the set value, the slower the feeding speed becomes, which will affect the work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low working efficiency when adding liquid raw materials, and to design an automatic proportioning device for environmentally friendly flame retardant raw materials.

[0005] To achieve the above objectives, the technical solution of this utility model is an automatic proportioning device for environmentally friendly flame retardant raw materials, comprising a metering cylinder, a discharge valve installed at the lower end of the metering cylinder, the lower end of the discharge valve being installed on a baffle at the upper end of a mixing vessel, the liquid raw material in the metering cylinder being added to the mixing vessel through the discharge valve, the metering cylinder having graduation lines, a limiting ring inside the metering cylinder being installed on the metering cylinder by a fixing frame, a metering block that can move up and down inside the metering cylinder, a liquid outlet on the metering block being located below the limiting ring, a pushing block being installed above the metering block, the metering block and the pushing block being connected by a connecting frame, a plug installed at the lower end of the pushing block being able to block the liquid outlet, and a lifting frame installed on the metering cylinder being able to drive the pushing block to move up and down.

[0006] Furthermore, the connecting frame includes guide rods installed on both sides of the upper end of the quantitative block, guide cylinders are installed on both sides of the pushing block, the guide rods can pass through the guide cylinders, and an interception plate is installed on the upper end of the guide rods.

[0007] Furthermore, the lifting frame includes a lifting plate located above the metering cylinder, the lifting plate and the push block are connected by a connecting rod, and multi-stage electric telescopic rods are installed on both sides of the lower surface of the lifting plate, with the fixed ends of the multi-stage electric telescopic rods installed on the metering cylinder.

[0008] Furthermore, the fixing frame includes lifting rods installed on both sides of the upper end of the limiting ring. The upper end of the lifting rod extends to the outside of the metering cylinder. The lifting plate has a circular hole to avoid the lifting rod. Limiting sleeves are installed on both sides of the upper end of the metering cylinder. The upper end of the lifting rod is provided with an external thread. Two limiting nuts are screwed on the external thread. The two limiting nuts are located at the upper and lower ends of the limiting sleeve.

[0009] Furthermore, a sealing ring is installed on the outside of the metering block, and a tapered tube is installed on the lower surface of the metering block.

[0010] The beneficial effects of this utility model are as follows: Liquid raw materials are added to a metering cylinder, allowing the liquid raw materials to overflow the metering block. The metering block is limited by a limiting ring, thus ensuring the accuracy of the feeding. Then, the lifting frame drives the pushing block to move downward. Since there is a gap between the pushing block and the metering cylinder, the excess liquid raw materials in the metering cylinder can flow to the top of the pushing block. When the plug blocks the liquid outlet, the liquid raw materials below the metering block are the metered raw materials. Then, the discharge valve is opened, and the lifting frame drives the pushing block and the metering block to move downward, which can add the metered liquid raw materials to the mixing vessel, thus realizing automatic proportioning. Since there is no need to use a metering pump to control the flow rate, the feeding efficiency can be improved, and the accuracy of the proportioning can also be guaranteed.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] This utility model provides, for example Figure 1-5 An automatic proportioning device for environmentally friendly flame retardant raw materials is shown, comprising a metering cylinder 1, a discharge valve 2 installed at the lower end of the metering cylinder 1, the lower end of the discharge valve 2 being installed on a baffle at the upper end of a mixing vessel, the liquid raw materials in the metering cylinder 1 being added to the mixing vessel through the discharge valve 2, the metering cylinder 1 having graduation lines, a limiting ring 3 inside the metering cylinder 1, the limiting ring 3 being installed on the metering cylinder 1 through a fixing frame 4, a metering block 5 that can move up and down inside the metering cylinder 1, a liquid outlet 6 on the metering block 5, the metering block 5 being located below the limiting ring 3, a pushing block 7 being provided above the metering block 5, the metering block 5 and the pushing block 7 being connected through a connecting frame 8, a plug 9 being installed at the lower end of the pushing block 7, the plug 9 being able to block the liquid outlet 6, and a lifting frame 10 being installed on the metering cylinder 1, the lifting frame 10 being able to drive the pushing block 7 to move up and down.

[0015] The process of quantitatively adding liquid raw materials using this device is as follows: Under normal conditions, the discharge valve 2 is closed, and the push block 7 is positioned above the quantitative block 5. The operator adds the liquid raw material into the quantitative cylinder 1. When the liquid raw material overflows the limiting ring 3, the lifting frame 10 drives the push block 7 to move downwards. The plug 9 at the lower end of the push block 7 can move to the liquid outlet 6 and block the liquid outlet 6. Then, the push block 7 can push the quantitative block 5 downwards, opening the discharge valve 2. When the quantitative block 5 moves downwards, the liquid raw material in the quantitative cylinder 1 can be added to the mixing vessel through the discharge valve 2. After the addition is completed, the discharge valve 2 is closed, and the lifting frame 10 drives the push block 7 to move upwards. When the liquid outlet 6 leaks out, the connecting frame 8 can pull the quantitative block 5 upwards. Finally, the limiting ring 3 blocks the quantitative block 5.

[0016] Refer to the instruction manual appendix Figure 3 Included with instruction manual Figure 4 The connecting frame 8 includes guide rods 11 installed on both sides of the upper end of the metering block 5. Guide cylinders 12 are installed on both sides of the pushing block 7. The guide rods 11 can pass through the guide cylinders 12. An intercepting plate 13 is installed on the upper end of the guide rods 11. When the pushing block 7 moves downward, the guide cylinders 12 and guide rods 11 can ensure the direction of movement of the pushing block 7. When the pushing block 7 contacts the metering block 5, it can push the metering block 5 downward. When the pushing block 7 moves upward, when the guide cylinders 12 move to the lower surface of the intercepting plate 13, the intercepting plate 13, guide rods 11 and metering block 5 can be pulled upward.

[0017] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The lifting frame 10 includes a lifting plate 14 located above the metering cylinder 1. The lifting plate 14 and the push block 7 are connected by a connecting rod 15. Multi-stage electric telescopic rods 16 are installed on both sides of the lower surface of the lifting plate 14. The fixed ends of the multi-stage electric telescopic rods 16 are installed on the metering cylinder 1.

[0018] The process of the lifting frame 10 driving the push block 7 to move is as follows: the multi-stage electric telescopic rod 16 is activated to extend or shorten, which can drive the lifting plate 14 to move up and down. The lifting plate 14 can drive the push block 7 to move up and down through the connecting rod 15.

[0019] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 5 The fixing frame 4 includes lifting rods 17 installed on both sides of the upper end of the limiting ring 3. The upper end of the lifting rods 17 extends to the outside of the metering cylinder 1. The lifting plate 14 has a round hole 18 to avoid the lifting rods 17. Limiting sleeves 19 are installed on both sides of the upper end of the metering cylinder 1. The upper end of the lifting rods 17 is provided with external threads, and two limiting nuts 20 are screwed on the external threads. The two limiting nuts 20 are located at the upper and lower ends of the limiting sleeves 19.

[0020] The process of installing the limiting ring 3 on the fixing frame 4 is as follows: the lifting rod 17 is passed through the limiting sleeve 19 and screwed onto the external thread of the lifting rod 17 by two limiting nuts 20, thereby fixing the lifting rod 17. By changing the position of the limiting nuts 20, the position of the lifting rod 17 and the limiting ring 3 can be adjusted, thereby adjusting the amount of liquid raw material in the metering cylinder 1.

[0021] Refer to the instruction manual appendix Figure 3 Included with instruction manual Figure 4 A sealing ring 21 is installed on the outside of the metering block 5, and a conical tube 22 is installed on the lower surface of the metering block 5. The sealing ring 21 can prevent liquid raw material leakage when the metering block 5 moves up and down. When liquid raw material is added to the metering cylinder 1, the conical tube 22 can allow air to be discharged through the conical tube 22, preventing air from accumulating below the positioning block 5.
