[0034] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0035] like Figure 1-5 As shown, the utility model provides a novel graphite material screening device, the screening device comprising: a screening box 1, a base 2, a screening plate 6 and a heating assembly;

[0036] A screening box 1 is vertically fixedly provided on the upper end of the base 2, and a partition 3 is vertically fixedly provided inside the screening box 1 for dividing the interior of the screening box 1 into a No. 1 storage chamber 4 and a No. 2 storage chamber 5, and a feed hopper 7 connected with the interior of the No. 2 storage chamber 5 located above the partition 3 is fixedly provided on the side wall of the No. 2 storage chamber 5 located above the partition 3, and a screening plate 6 is obliquely fixedly provided on the No. 2 storage chamber 5 located between the feed hopper 7 and the partition 3, and the heating assembly is fixedly provided on the base 2 so that the heated gas can enter the No. 1 storage chamber 4 and the No. 2 storage chamber 5 to dry the screened raw materials, and the No. 1 storage chamber 4 and the No. 2 storage chamber 5 are respectively provided with a No. 1 stirring mechanism 8 and a No. 2 stirring mechanism 9 for stirring the screened materials.

[0037] In the above scheme, when in use, the raw materials to be screened are injected from the feed hopper 7 into the screening box 1 and screened by the inclined screening plate 6. In the process of small-particle raw materials rolling down along the inclined screening plate 6, they fall into the No. 2 storage chamber 5 through the screening holes on the screening plate 6, while large-particle raw materials roll along the inclined screening plate 6 into the No. 1 storage chamber 4, thereby completing the screening effect.

[0038] During the screening process, the heating component is started to continuously inject heated gas into the No. 1 storage chamber 4 and the No. 2 storage chamber 5 to heat and dry the large-particle raw materials and small-particle raw materials after screening, so as to dry the raw materials.

[0039] During the process of drying the raw materials, the screened raw materials in the No. 1 storage chamber 4 and the No. 2 storage chamber 5 can be stirred respectively by the No. 1 stirring mechanism 8 and the No. 2 stirring mechanism 9, so that the screened raw materials in the No. 1 storage chamber 4 and the No. 2 storage chamber 5 can be fully in contact with the gas heated by the heating component, so as to improve the drying efficiency and drying effect.

[0040] In addition, an exhaust pipe connected to the interior of the screening box 1 is fixedly provided on the top of the screening box 1 so as to discharge the gas in the screening box 1 .

[0041] In a preferred embodiment of the present invention, the first stirring mechanism 8 and the second stirring mechanism 9 have the same structure, and the first stirring mechanism 8 comprises: a rotating shaft of a tubular structure and a plurality of stirring blades horizontally and evenly fixedly arranged on the rotating shaft; wherein,

[0042] The rotating shaft located inside the screening box 1 is also evenly provided with a plurality of air outlet holes 10 connected with the interior thereof, and the bottom end of the rotating shaft extends from the interior of the screening box 1 to the base 2, and the bottom end thereof is open, and the two air pipes 18 of the heating assembly partially extend into the interior of the rotating shafts of the No. 1 stirring mechanism 8 and the No. 2 stirring mechanism 9, respectively.

[0043] In the above scheme, when in use, the gas heated by the heating component passes through the gas pipe 18 and the rotating shafts of the No. 1 stirring mechanism 8 and the No. 2 stirring mechanism 9 to enter the No. 1 storage chamber 4 and the No. 2 storage chamber 5 respectively, so that the No. 1 stirring mechanism 8 and the No. 2 stirring mechanism 9 can release the gas heated by the heating component into the two storage chambers through the several air outlet holes 10 on the rotating shafts of the two during the process of stirring the raw materials in the two storage chambers, so as to fully dry the screened raw materials in the two storage chambers.

[0044] In a preferred embodiment of the present invention, the heating assembly includes: an air intake pump 12 for sucking external air into the air heater 11 and an air heater 11 for heating the air entering the air heater; wherein,

[0045] The air heater 11 is fixed inside the base 2, the air intake pump 12 is fixedly arranged on the outer wall of the base 2, and the output end of the air intake pump 12 penetrates into the interior of the screening box 1 and is connected with the interior of the air heater 11, and two air delivery pipes 18 are respectively connected and fixedly arranged on the air heater 11 and can extend into the interior from the bottom ends of the rotating shafts of the first stirring mechanism 8 and the second stirring mechanism 9 respectively.

[0046] In the above scheme, the external air is transported to the air heater 11 through the air intake pump 12, and the gas heated by the air heater 11 enters the two rotating shafts of the No. 1 stirring mechanism 8 and the No. 2 stirring mechanism 9 respectively through the two air pipes 18 and is released to the No. 1 storage chamber 4 and the No. 2 storage chamber 5 through the multiple air outlet holes 10 on the two rotating shafts to dry the raw materials in the two storage chambers.

[0047] In addition, the air heater 11 is a well-known technical means. The air heater is an electric heating device that mainly heats the gas flow. The heating element of the air heater is a stainless steel electric heating tube. The inner cavity of the heater is provided with a plurality of baffles (guide plates) to guide the gas flow and prolong the retention time of the gas in the inner cavity, so that the gas is fully heated, the gas is heated evenly, and the heat exchange efficiency is improved. The heating element of the air heater is a stainless steel heating tube, so its specific structure and use principle will not be repeated here.

[0048] In a preferred embodiment of the present invention, a filter cloth or a filter screen is fixedly provided on each of the air outlet holes 10 to prevent the raw materials from entering the rotating shaft through the air outlet holes 10 .

[0049] In the above scheme, when the first stirring mechanism 8 and the second stirring mechanism 9 are stirring the raw materials, the raw materials are prevented from entering the rotating shaft through the air outlet 10 and causing leakage of the raw materials.

[0050] In a preferred embodiment of the present invention, a rubber layer 17 is horizontally fixedly provided at the bottom end of the rotating shaft of the No. 1 stirring mechanism 8 and the No. 2 stirring mechanism 9, and the tops of the two air pipes 18 of the heating assembly partially pierce the corresponding rubber layer 17 and extend into the rotating shaft.

[0051] In the above scheme, when in use, since the end of the air pipe 18 pierces the rubber layer 17 on the end of the rotating shaft and extends into the interior of the rotating shaft, the rotating shaft will not drive the air pipe 18 to rotate together with it during rotation, and the two complement each other. In addition, the rubber layer 17 can make the end of the rotating shaft have good sealing performance, so that during the rotation of the rotating shaft, the side wall of the air pipe 18 is in contact with the rubber layer 17. Therefore, when the gas heated by the heating component enters the rotating shaft through the air pipe 18, under the sealing effect of the rubber layer 17, the gas can only be released into the No. 1 storage chamber 4 and the No. 2 storage chamber 5 through the several air outlet holes 10 on the rotating shaft.

[0052] In a preferred embodiment of the present invention, the side walls at the bottom ends of the No. 1 storage chamber 4 and the No. 2 storage chamber 5 are respectively provided with discharge ports connected to their respective interiors, and each discharge port is detachably provided with a cover plate 15 that can cover the discharge port.

[0053] In the above scheme, the raw materials after screening and drying can be discharged through the discharge port.

[0054] Before use, the two discharge ports are blocked by the cover plate 15 to prevent the raw materials after screening or other processing from scattering out from the discharge ports during use.

[0055] In a preferred embodiment of the present invention, the screening device further comprises a driving assembly 14 for driving the rotating shafts of the first stirring mechanism 8 and the second stirring mechanism 9 to rotate synchronously, and the driving assembly 14 comprises: a driving motor, a driving gear, a driven gear, a chain and a sprocket; wherein,

[0056] A support plate 13 is fixedly arranged horizontally inside the base 2, and the bottom end portions of the two rotating shafts extend to the bottom of the support plate 13. The air intake pump 12 is fixed in the base 2 below the support plate 13. A chain is respectively assembled on the two rotating shafts above the support plate 13 through a sprocket, and a driven gear is coaxially fixedly arranged on any one of the rotating shafts, and a driving motor is vertically fixedly arranged on the support plate 13 next to the driven gear, and a driving gear meshingly connected to the driven gear is coaxially arranged on the output shaft of the driving motor.

[0057] In the above scheme, when in use, the driving motor is started to drive the driving gear on its output shaft to rotate, and under the meshing relationship between the driving gear and the driven gear, the rotating shaft fixedly connected to the driven gear can be driven to rotate, and because the two rotating shafts are connected together through a chain drive, the two shafts rotate synchronously.

[0058] In a preferred embodiment of the present invention, a vibrator 16 is fixedly provided at the bottom end of the screening plate 6 .

[0059] In the above scheme, the vibrator 16 can make the screening plate 6 vibrate, so that the raw materials falling on the screening plate 6 can roll more smoothly, so as to prevent the raw materials from piling up on the screening plate 6 and reducing the screening effect.

[0060] The vibrator 16 is a prior art, the working part of which is a rod-shaped hollow cylinder, with an eccentric vibrator installed inside, which rotates at high speed under the drive of the motor to generate high-frequency slight vibration, and the vibration frequency can reach 12000-15000 times / min, with good vibration effect, simple structure and long service life. It is suitable for vibrating components such as beams, columns, plates, walls and large-volume concrete, so its specific structure and use principle will not be repeated here.

[0061] In summary, the new graphite material screening device provided by the utility model overcomes the problem that the large particles of graphite accumulated on the screen in the prior art need to be manually cleaned regularly, which reduces the screening efficiency. Since graphite has an adsorption function, after being placed for a period of time, it can absorb moisture in the air, increasing the humidity inside the graphite, which is not conducive to the use of graphite. Therefore, the screened graphite needs to be transferred to a drying device for drying before the graphite raw material can be processed.

[0062] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0064] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
