Description

Technical Field

[0001] This utility model relates to the field of new energy material preparation technology, and in particular to a quantitative feeding dryer / atomizer for lithium iron phosphate cathode materials. Background Technology

[0002] Lithium-ion batteries are an important part of the new energy field and have been widely used in electric vehicles, energy storage systems and other fields. Lithium iron phosphate, as the cathode material of lithium-ion batteries, has become a popular choice in the market due to its advantages such as high safety, long life and low cost.

[0003] In the preparation process of lithium iron phosphate cathode material, the liquid material is sprayed into extremely fine mist droplets by an atomizer, and then the mist droplets are fully heat-exchanged by hot air to achieve rapid drying and ensure the stability and performance of the material.

[0004] However, existing liquid feeding methods typically introduce liquid into the drying equipment through continuous feeding, which makes it difficult to accurately control the flow rate of the liquid. This results in problems such as unstable flow rate and uneven drying effect. Alternatively, multiple devices are required to achieve quantitative feeding, such as flow monitoring equipment, control valves, and drive equipment. This makes actual operation inconvenient and costly. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that use a continuous feeding method to introduce liquid into the drying equipment, which makes it difficult to accurately control the flow rate of the liquid, resulting in unstable flow and uneven drying effect, or require multiple devices to cooperate to achieve quantitative feeding. Therefore, this invention proposes a quantitative feeding lithium iron phosphate cathode material drying atomizer.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quantitative feeding lithium iron phosphate cathode material drying atomizer includes an atomizer body, the top of which is fixedly connected to a feed pipe;

[0008] A metering component is used for metering the addition of liquid feed. The metering component is located on the top of the atomizer body. The metering component includes a dispensing cylinder and a slider slidably disposed inside the dispensing cylinder. The dispensing cylinder is located above the atomizer body. Discharge holes are opened on both sides of the bottom of the outer wall of the dispensing cylinder. Two connecting pipes are fixedly connected to the outer wall of the feed pipe. One end of the two connecting pipes is connected to the two discharge holes respectively. Connecting rods are fixedly installed at both ends of the slider. A sealing plate is fixedly installed at one end of the connecting rod. A feeding pipe is fixedly connected to the top of the dispensing cylinder.

[0009] In one possible design, a sliding hole is provided on one side of the dispensing cylinder, and a side rod is fixedly provided on the outer wall of the slider, with the side rod extending to the outside of the dispensing cylinder through the sliding hole.

[0010] In one possible design, the metering component further includes an outer plate, a bottom box is fixedly mounted on the top of the atomizer body, the dispensing cylinder is fixedly mounted on the top of the bottom box, a fixed shaft is fixedly mounted on one side of the bottom box, one end of the outer plate is rotatably sleeved on the outer wall of the fixed shaft, an inner plate is rotatably mounted on the outer wall of the side rod, and one end of the inner plate extends through the interior of the outer plate.

[0011] In one possible design, a servo motor is fixedly installed inside the base box. The output shaft of the servo motor rotates through to the outside of the base box. A rotating plate is fixedly sleeved on the outer wall of the servo motor output shaft. A rotating rod is fixedly installed on one side of the rotating plate. A limit hole is opened on one side of the outer plate, and one end of the rotating rod is located inside the limit hole.

[0012] In one possible design, a protective plate is fixedly fitted onto the outer wall of the side rod, and the protective plate is in contact with the outer wall of the dispensing cylinder.

[0013] In one possible design, a rubber pad is fixedly installed on one side of the sealing plate.

[0014] In this application, during actual use, the liquid is delivered to the inside of the dispensing cylinder through the feeding pipe, and then a servo motor is driven. The servo motor drives the rotating plate to rotate, and the rotating plate drives the rotating rod to rotate. The rotating rod will drive the outer plate to swing back and forth along the fixed axis inside the limiting hole. When the fixed axis is tilted, the inner plate and the fixed axis will be relatively extended and drive the side rod to move, realizing the reciprocating movement of the side rod. The side rod drives the slider to move, and the slider drives the sealing plate to move through the connecting rods at both ends. When the slider moves to the left side of the feeding pipe, the liquid will enter between the slider and the sealing plate on the right side. Then, when the slider moves to the right side so that the discharge hole is located between the slider and the sealing plate, the previously stored liquid is added to the inside of the atomizer body through the connecting pipe and the feeding pipe. At this time, the liquid will enter the left side of the slider and the left sealing plate for storage. This cycle repeats. By controlling the number of reciprocating movements of the slider, the effect of quantitative feeding can be achieved.

[0015] In this utility model, the quantitative feeding lithium iron phosphate cathode material drying atomizer can achieve the reciprocating motion of the slider of the quantitative component and the sealing plates on both sides, so as to realize the operation of feeding and unloading at the same time, and the amount is the same each time, thereby achieving the effect of quantitative feeding by controlling the number of slider movements.

[0016] In this utility model, the quantitative feeding lithium iron phosphate cathode material drying atomizer can drive the side outer plate to swing back and forth through the servo motor of the quantitative component, thereby cooperating with the upper slider to achieve reciprocating motion, so as to achieve the effect of quantitative feeding. The structure is simple, and it is only necessary to control the servo motor to drive the slider to move a specified number of times.

[0017] In this invention, after the liquid is added into the dispensing cylinder, the servo motor of the metering component drives the slider to reciprocate laterally, thereby achieving the effect of receiving and unloading material at the same time. The purpose of quantitative feeding can be achieved by controlling the number of times the slider moves. The structure is simple and easy to operate, without the need for multiple devices to cooperate, making it convenient for actual operation and use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0025] Reference Figure 1 A drying atomizer includes: an atomizer body 1, with a feed pipe 2 fixedly connected to the top of the atomizer body 1. The feed pipe 2 is used to introduce liquid into the interior of the atomizer body 1. The atomizer is used to spray the liquid into extremely fine mist droplets so that it can fully contact with hot air and dry quickly.

[0026] This application can be used in the field of new energy material preparation, or in other fields applicable to this application. Example

[0027] refer to Figure 4 An improvement upon Example 1 is presented: a quantitative feeding lithium iron phosphate cathode material drying atomizer, applied in the field of new energy material preparation. To achieve quantitative addition of the feed liquid, a quantitative component is installed on the top of the atomizer body 1. The quantitative component includes a dispensing cylinder 7 and a slider 8 slidably disposed inside the dispensing cylinder 7. The dispensing cylinder 7 is located above the atomizer body 1, and discharge holes 19 are opened on both sides of the bottom of its outer wall. Two connecting pipes 13 are fixedly connected to the outer wall of the feed pipe 2, and one end of each connecting pipe 13 is connected to one of the two discharge holes 19.

[0028] Connecting rods 20 are fixedly installed at both ends of the slider 8, and a sealing plate 22 is fixedly installed at one end of the connecting rod 20. The sealing plate 22 is used to block or open the discharge hole 19 when the slider 8 slides. In order to increase the sealing effect, a rubber pad 21 is also fixedly installed on one side of the sealing plate 22 to prevent material leakage.

[0029] A feeding pipe 9 is fixedly connected to the top of the dispensing cylinder 7 for adding liquid into the dispensing cylinder 7. To facilitate the control of the sliding of the slider 8, a sliding hole 11 is provided on one side of the dispensing cylinder 7, and a side rod 10 is fixedly provided on the outer wall of the slider 8. The side rod 10 extends to the outside of the dispensing cylinder 7 through the sliding hole 11, so that the operator can drive the side rod 10 through an external mechanism, thereby causing the slider 8 to slide inside the dispensing cylinder 7.

[0030] Reference Figure 2-3 Furthermore, the metering assembly also includes components such as an outer plate 15, a base box 17, a fixed shaft 16, a servo motor 4, a rotating plate 5, and a rotating rod 12. The base box 17 is fixedly mounted on the top of the atomizer body 1, and the fixed shaft 16 is fixedly mounted on one side of the base box 17. One end of the outer plate 15 is rotatably sleeved on the outer wall of the fixed shaft 16, and an inner plate 6 is rotatably mounted on the outer wall of the side rod 10. One end of the inner plate 6 passes through the interior of the outer plate 15 and is fixedly connected to the outer plate 15.

[0031] The servo motor 4 is fixedly installed inside the base box 17, and its output shaft rotates through to the outside of the base box 17 and is fixedly fitted with a rotating plate 5. A rotating rod 12 is fixedly installed on one side of the rotating plate 5, and a limit hole 14 is opened on one side of the outer plate 15. One end of the rotating rod 12 is located inside the limit hole 14. When the servo motor 4 is started, it will drive the rotating plate 5 and the rotating rod 12 to rotate together. Since one end of the rotating rod 12 is located inside the limit hole 14, the rotation of the rotating rod 12 will drive the outer plate 15 to rotate around the fixed shaft 16, thereby realizing the sliding control of the slider 8.

[0032] Specifically, the liquid is conveyed to the inside of the dispensing cylinder 7 through the feeding pipe 9, and then the servo motor 4 is driven. The servo motor 4 drives the rotating plate 5 to rotate, and the rotating plate 5 drives the rotating rod 12 to rotate. The rotating rod 12 will drive the outer plate 15 to swing back and forth along the fixed shaft 16 inside the limiting hole 14. When the fixed shaft 16 is tilted, the inner plate 6 and the fixed shaft 16 will be relatively extended and drive the side rod 10 to move, realizing the reciprocating movement of the side rod 10. The side rod 10 drives the slider 8 to move, and the slider 8 drives the sealing plate 22 to move through the connecting rods 20 at both ends. When the slider 8 moves to the feeding pipe 9, the sealing plate 22 moves. When the slider is on the left, the liquid will enter between the slider 8 and the sealing plate 22 on the right. Then, when the slider 8 moves to the right so that the outlet 19 is located between the slider 8 and the sealing plate 22, the previously stored liquid is added to the interior of the atomizer body 1 through the connecting pipe 13 and the feed pipe 2. At this time, the liquid will enter the left side of the slider 8 and the left sealing plate 22 for storage. This cycle repeats. By controlling the number of reciprocating movements of the slider 8, the effect of quantitative feeding can be achieved. The structure is simple and easy to operate. It does not require the cooperation of multiple devices and is convenient for actual operation and use.

[0033] Reference Figure 5 The outer wall of the side rod 10 is fixedly fitted with a protective plate 18, and the protective plate 18 is in contact with the outer wall of the distributing cylinder 7 to prevent the liquid from being discharged through the sliding hole 11.

[0034] However, as is well known to those skilled in the art, the working principle and wiring method of the servo motor 4 and the atomizer body 1 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
