Description

Technical Field

[0001] This utility model relates to the field of graphite powder recycling technology, and in particular to a graphite powder recycling device with a multi-stage screening mechanism. Background Technology

[0002] Graphite is a crystalline form of carbon. It belongs to the hexagonal crystal system and ranges in color from iron-black to dark gray. Its density is 2.25 g / cm³, hardness is 1.5, melting point is 3652℃, and boiling point is 4827℃. It is soft, has a slippery feel, and is electrically conductive. Chemically inert, it is corrosion-resistant and does not readily react with acids or alkalis.

[0003] However, in the existing technology, the structure of the screening and recycling device for graphite powder is relatively simple, which cannot perform multi-stage screening of graphite powder. The screening is relatively coarse, which is not conducive to the subsequent use of graphite powder. Moreover, the dust generated during the screening of graphite powder will pollute the air. Therefore, we propose a graphite powder recycling device with a multi-stage screening mechanism. Utility Model Content

[0007] Preferably, the transmission mechanism includes a pulley fixedly sleeved on the outer wall of the connecting shaft, and two adjacent pulleys are connected by belt drive.

[0008] Preferably, the power mechanism includes a motor that is horizontally fixedly installed on the outer wall of the housing, wherein one of the connecting shafts is fixedly connected to the output shaft of the motor.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting multiple sieve plates with mesh sizes decreasing from top to bottom, and using a motor and cams to indirectly drive the multiple sieve plates to vibrate up and down, the graphite powder is screened in multiple stages, dividing it into multiple groups for finer screening, which is more conducive to the subsequent use of the graphite powder.

[0013] 2. By setting up electric push rods and grooving plates and other components, the box can be adjusted to a tilted state, which makes it easy to pour out the graphite powder inside the box. Multiple discharge ports are set up to separate the removal of graphite powder of different specifications. An air outlet pipe is set up, which is connected to a fan and a filter bag to suck the dust raised by screening into the filter bag for filtration and reduce air pollution.

[0021] The following is in conjunction with the appendix Figure 1-3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0022] like Figure 1-3 As shown, this utility model discloses a graphite powder recovery device with a multi-stage sieving mechanism, comprising a base plate 1, a vertically arranged box 2 rotatably mounted on the upper surface of the base plate 1, a box cover rotatably mounted on the upper part of the box 2, a rotation control mechanism connected to the box 2, and multiple sieving plates 3 slidably fitted from top to bottom on the inner wall of the box 2, the mesh size of the multiple sieving plates 3 decreasing sequentially from top to bottom, and a connecting shaft 4 rotatably penetrating the box 2 being arranged horizontally below each of the multiple sieving plates 3, with a cam 5 fixedly sleeved on the outer wall of the connecting shaft 4 on the lower surface of the sieving plate 3, the multiple connecting shafts 4 being connected by a transmission mechanism. The device includes a pulley 13 fixedly sleeved on the outer wall of the connecting shaft 4. Two adjacent pulleys 13 are connected by a belt 14. One of the connecting shafts 4 is connected to a power mechanism, which includes a motor 15 horizontally fixedly installed on the outer wall of the housing 2. One of the connecting shafts 4 is fixedly connected to the output shaft of the motor 15. An exhaust pipe 6 is fixedly connected to the upper part of one side of the housing 2. An exhaust fan 7 is installed on the exhaust pipe 6. A filter bag 8 is installed at the end of the exhaust pipe 6. An air inlet pipe 9 is installed at the lower part of one side of the housing 2. This device performs multi-stage screening by setting multiple screening plates 3, and at the same time treats dust to reduce air pollution.

[0023] Specifically, the rotation control mechanism includes an electric push rod 10 vertically fixedly installed on the upper surface of the base plate 1. The free end of the electric push rod 10 is laterally rotatably mounted with an adjusting shaft 11. A slotted plate 12 is laterally fixedly installed on the outer wall of the box 2. The adjusting shaft 11 moves through the slot of the slotted plate 12. The electric push rod 10 can control the tilt angle of the box 2 to pour out the graphite powder inside the box 2, making it more convenient to remove the graphite powder.

[0024] More specifically, the side wall of the box 2 has multiple discharge ports, and a sealing plate 16 is slidably installed on the inner wall of the discharge port. The sealing plate 16 is fixedly connected to the box 2 by screws. Each layer of graphite powder obtained by screening corresponds to a discharge port, so that each layer of graphite powder can be taken out in batches.

[0025] Furthermore, filter screens are respectively installed at the ends of the air inlet pipe 9 and the air outlet pipe 6 near the housing 2. Both the air inlet pipe 9 and the air outlet pipe 6 are inclined. The filter screens are used to block graphite powder and prevent graphite powder from entering the air inlet pipe 9 or the air outlet pipe 6. The inclined arrangement of the air inlet pipe 9 and the air outlet pipe 6 can prevent graphite powder from entering.

[0026] Working principle:

[0027] In use, open the lid and pour the graphite powder into the chamber 2. Control the start motor 15, which drives the connecting shaft 4 directly connected to it to rotate. Through the transmission of the belt 14 and the connecting shaft 13, the remaining connecting shaft 4 is indirectly driven to rotate. The connecting shaft 4 drives the corresponding cam 5 to rotate. The rotation of the cam 5 causes the screening plate 3 to vibrate up and down. The graphite powder is screened through multiple screening plates 3 in sequence. Graphite powder is left on multiple screening plates 3 and the bottom surface of the chamber 2. After screening, turn off the motor 15 and turn on the exhaust fan 7. The exhaust fan 7 sends the dust in the chamber 2 into the filter bag 8 for filtration and purification. When taking out the material, control the electric push rod 10 to extend and drive the adjusting shaft 11 to move upward. The adjusting shaft 11 indirectly drives the chamber 2 to rotate through the transmission of the slotted plate 12, causing the chamber 2 to rotate to an inclined position. Then, open multiple sealing plates 16 in sequence to take out the screened graphite powder in batches.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
