[0002] When recycling waste oil, it is necessary to collect the waste oil, pre-treat the waste oil, separate the waste oil and refine the waste oil. Among them, the waste oil refining is to further process the separated recyclable oil substances to make them meet the requirements of reuse. During the operation step of waste oil refining, a crystallizing agent needs to be added to the waste oil. However, when adding the crystallizing agent, the dosage of the crystallizing agent cannot be well controlled. In response to the above problems, the inventors proposed a quantitative device with adjustable dosage to solve the above problems. Utility Model Content

[0005] Preferably, the top surface of the indicator plate is flush with the top surface of the first piston. When the first piston moves up and down, the indicator plate can move up and down in the cavity under the action of attraction between the strong magnetic block and the magnetic attraction plate. The position of the indicator plate can be known through the scale line. Since the top surface of the indicator plate is flush with the top surface of the first piston, the position of the first piston in the cylinder can be known, and then the adjusted capacity in the cylinder can be known.

[0006] Preferably, a liquid inlet pipe is fixedly connected to one side of the top surface of the cylinder cover, and a liquid outlet pipe is fixedly connected to the top surface of the cylinder cover and one side of the liquid inlet pipe. A pump body is placed on the top surface of the first piston, and the output end of the pump body is fixedly connected to the input end of the liquid outlet pipe, and the output end of the liquid outlet pipe is fixedly connected to the first connector. The crystallizer for waste oil treatment can be filled into the cylinder through the liquid inlet pipe, and the pump body can be started to extract the quantitative crystallizer through the liquid outlet pipe for use. A vertical cylinder is fixedly connected to the middle part of the inner bottom wall of the cylinder, and a lifting rod is inserted and slidably connected to the middle part of the top surface of the vertical cylinder, the top end of the lifting rod is fixedly connected to the bottom surface of the first piston, and the bottom end of the lifting rod is fixedly connected to the second piston, and the second piston cooperates with the cylinder mouth of the vertical cylinder. An air pipe is fixedly connected to the lower part of the side wall of the vertical cylinder, and the air pipe One end passes through the cylinder, and the end of the air pipe away from the vertical cylinder is fixedly connected to the second connecting head, the bottom surface of the first piston is fixedly connected to a spring, and the end of the spring away from the first piston is fixedly connected to a fixed platform, and the bottom surface of the fixed platform is fixedly connected to the inner bottom wall of the cylinder. There are three springs, and the three springs are distributed in an array with the axis of the cylinder as the center. The second connecting head is used to communicate with the port of an external air charging and discharging pump. When air is inflated into the vertical cylinder through the air pipe, the second piston will move upward, thereby driving the first piston to move upward through the lifting rod. At this time, the capacity in the cylinder becomes smaller, and the capacity in the cylinder can be checked through the indicator plate and the scale line. At this time, the spring is in a stretched state. When deflated, under the action of the spring force, the first piston can fall, so that the capacity in the cylinder becomes larger.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Example: Figure 1-4 As shown, the utility model provides a quantitative device with adjustable dosage, including a cylinder 1, a cylinder cover 2 is fixedly connected to the top surface of the cylinder 1, a first piston 7 is arranged inside the cylinder 1 so as to be liftable, a strong magnetic block 13 is embedded and fixedly connected to the side wall of the first piston 7, a convex cavity 16 is fixedly connected to the outer wall of the cylinder 1, the convex cavity 16 includes a cavity opening 18, a magnetic plate 19 is slidably connected to the cavity opening 18, the magnetic plate 19 corresponds to the strong magnetic block 13 and attracts each other, an indicator plate 20 is fixedly connected to the end surface of the magnetic plate 19, and a scale line 17 is provided on the outer wall of the convex cavity 16.

[0016] The top surface of the indicator plate 20 is flush with the top surface of the first piston 7 .

[0017] By adopting the above technical solution, when the first piston 7 moves up and down, the strong magnetic block 13 and the magnetic plate 19 are attracted to each other, so that the indicator plate 20 can move up and down in the cavity 18. The position of the indicator plate 20 can be known through the scale line 17. Since the top surface of the indicator plate 20 is flush with the top surface of the first piston 7, the position of the first piston 7 in the cylinder 1 can be known, and then the adjusted capacity in the cylinder 1 can be known.

[0018] A liquid inlet pipe 3 is fixedly connected to one side of the top surface of the cylinder cover 2, and a liquid outlet pipe 4 is fixedly connected to the top surface of the cylinder cover 2 and on one side of the liquid inlet pipe 3. A pump body 5 is placed on the top surface of the first piston 7, and the output end of the pump body 5 is fixedly connected to the input end of the liquid outlet pipe 4, and the output end of the liquid outlet pipe 4 is fixedly connected to the first connector 6.

[0019] By adopting the above technical solution, the crystallizer for waste oil treatment can be filled into the cylinder 1 through the liquid inlet pipe 3, and the pump body 5 is started to extract the quantitative crystallizer through the liquid outlet pipe 4 for use.

[0020] A vertical cylinder 8 is fixedly connected to the middle of the inner bottom wall of the cylinder 1, and a lifting rod 11 is inserted and slidably connected to the middle of the top surface of the vertical cylinder 8. The top of the lifting rod 11 is fixedly connected to the bottom surface of the first piston 7, and the bottom end of the lifting rod 11 is fixedly connected to the second piston 12. The second piston 12 cooperates with the cylinder mouth of the vertical cylinder 8. An air pipe 9 is inserted and fixedly connected to the lower part of the side wall of the vertical cylinder 8. One end of the air pipe 9 passes through the cylinder 1, and the end of the air pipe 9 away from the vertical cylinder 8 is fixedly connected to the second connector 10. A spring 14 is fixedly connected to the bottom surface of the first piston 7, and the end of the spring 14 away from the first piston 7 is fixedly connected to a fixing platform 15. The bottom surface of the fixing platform 15 is fixedly connected to the inner bottom wall of the cylinder 1. There are three springs 14, and the three springs 14 are distributed in an array with the axis of the cylinder 1 as the center.

[0021] By adopting the above technical solution, the second connector 10 is used to communicate with the port of the external air pump. When air is inflated into the vertical cylinder 8 through the air pipe 9, the second piston 12 will move upward, thereby driving the first piston 7 to move upward through the lifting rod 11. At this time, the capacity of the cylinder 1 becomes smaller, and the capacity in the cylinder 1 can be checked through the indicator plate 20 and the scale line 17. At this time, the spring 14 is in a stretched state. When deflated, under the action of the elastic force of the spring 14, the first piston 7 can fall, so that the capacity in the cylinder 1 becomes larger.

[0023] The second connector 10 is provided for communicating with the port of an external air pump. When air is inflated into the vertical cylinder 8 through the air pipe 9, the second piston 12 moves upward, thereby driving the first piston 7 upward through the lifting rod 11. Under the action of the strong magnetic block 13 and the magnetic plate 19 attracting each other, the indicator plate 20 can be moved in the cavity 18. The position of the indicator plate 20 can be known by the scale line 17, and thus the position of the first piston 7 in the cylinder body 1 can be known. The capacity in the cylinder body 1 can be indicated by the indicator plate 20 and the scale line 17. At this time, the spring 14 is in a stretched state.

[0024] When deflation is performed, the first piston 7 is caused to fall under the action of the elastic force of the spring 14, so that the capacity in the cylinder 1 becomes larger, thereby achieving an effect of adjustable dosage.

Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
