Description

Technical Field

[0001] The present application relates to the field of graphite powder processing, and in particular to a graphite mixer. Background Art

[0002] Graphite mixer is a machine that further crushes graphite powder by stirring. The entire production process involves the process of graphite powder entering the mixing chamber and receiving the graphite powder after the graphite powder is processed.

[0003] In the prior art, the feeding method of the graphite mixer is usually to pour the material from the upper feeding port, or to blow it into the mixing chamber with a positive pressure blower. The pouring process is prone to dust and material waste. During the positive pressure blowing process, the pressure of the chamber increases, and graphite leakage is likely to occur at the gap of the machine. The discharge method of the graphite mixer is usually to transport the material through a pipeline or to set a receiving device directly under the discharge port, and no isolation measures are taken for dust. Since graphite powder is adhesive and light, pipeline transportation relies solely on the graphite powder's own gravity to slide, which can easily cause graphite to adhere to the pipeline, and is more likely to cause pipeline blockage or static agglomeration. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a graphite mixer which solves the problems in the prior art of dust and raw material waste caused by loading and unloading, graphite powder leakage caused by positive pressure loading of the machine, blockage caused by accumulation of graphite powder in the pipeline due to the adhesion of graphite powder, and easy agglomeration of graphite powder when left standing after receiving the materials.

[0005] The utility model is realized through the following technical scheme: a graphite mixer, comprising a feed barrel and a sealed mixing bin, the feed barrel and the mixing bin are connected through a feed pipe, a first motor is arranged at the bottom of the mixing bin, a first stirring device is arranged inside the mixing bin, the first stirring device adopts a general stirring structure of a graphite mixer, the first stirring device is driven by a first motor, the mixing bin is fixedly arranged on a first bracket, a discharge port is arranged on the other side of the mixing bin, a material receiving barrel is arranged below the discharge port, the material receiving barrel is arranged on a second bracket, an isolation cover is arranged between the discharge port and the material receiving barrel, and the isolation cover cover body is a flexible non-porous material; a fan is arranged on one side of the mixing bin, the fan is connected with the inside of the mixing bin through a negative pressure pipe, a filter plate socket is arranged at the connection point between the negative pressure pipe and the mixing bin, a filter plate is arranged in the filter plate socket, a second stirring device is arranged at the bottom of the receiving barrel, the second stirring device adopts a general stirring mechanism of a graphite mixer, a second motor is arranged at the bottom outside the receiving barrel, and the second stirring device is driven by the second motor.

[0006] Furthermore, the bottom of the feed barrel is fixedly connected to the side of the mixing bin through a feed pipe.

[0007] Furthermore, a throttle valve is arranged on the negative pressure pipeline.

[0008] Furthermore, the filtering device comprises a filter plate socket and a filter plate, and the filter plate can be inserted into the filter plate socket.

[0009] Furthermore, a negative pressure gauge is provided on the mixing chamber.

[0010] Furthermore, a sealing cover is provided at the discharge port.

[0011] Furthermore, a first magnetic strip and a second magnetic strip are provided on the isolation cover, and the isolation cover is connected to the discharge port and the receiving barrel respectively through the first magnetic strip and the second magnetic strip.

[0012] Furthermore, the second bracket is provided with a lockable universal wheel.

[0013] Furthermore, the second bracket is fixedly connected to the first bracket via a fixed connecting plate, and the fixed connecting plate is removable.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the machine adopts negative pressure feeding, and the air in the mixing chamber is extracted by the fan to form a negative pressure in the mixing chamber, and the graphite powder is sucked into the mixing chamber.

Compared with the traditional feeding mechanism, the graphite powder is quickly sucked into the mixing chamber, and the adhesion of the graphite powder in the feeding pipe will be greatly improved. At the same time, the traditional mixing machine will not take measures to prevent dust when receiving the material. The machine is provided with an isolation cover installed by a magnetic strip between the receiving barrel and the discharge port to prevent dust and waste of raw materials. The installation is quick and easy, and the cost is low. After receiving the graphite powder, a second stirring device is also provided in the receiving barrel to keep the graphite powder moving without agglomeration. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, this embodiment provides a graphite mixer, including a feed barrel 1 and a sealed stirring chamber 4, the feed barrel 1 and the stirring chamber 4 are connected through a feed pipe 2, a first motor 42 is arranged at the bottom of the stirring chamber 4, and a first stirring device 41 is arranged inside the stirring chamber 4, the first stirring device 41 adopts a universal stirring structure of a graphite mixer, the first stirring device 41 is driven by the first motor 42, the stirring chamber 4 is fixedly arranged on a first bracket 43, a discharge port 45 is further arranged on one side of the stirring chamber 4, a receiving barrel 61 is arranged below the discharge port 45, and the receiving barrel 61 is arranged below the discharge port 45. 1 is arranged on the second bracket 63, an isolation cover 5 is arranged between the discharge port 45 and the receiving barrel 61, and the cover body of the isolation cover 5 is made of a flexible non-porous material; a fan 31 is arranged on one side of the stirring chamber 4, and the fan 31 is connected with the inside of the stirring chamber 4 through a negative pressure pipe 32, and a filter device 36 is arranged at the connection between the negative pressure pipe 32 and the stirring chamber 4, a second stirring device 64 is arranged at the bottom of the receiving barrel 61, and the second stirring device 64 adopts a universal stirring mechanism of a graphite mixer, and a second motor 65 is arranged at the bottom of the receiving barrel 61, and the second stirring device 64 is driven by the second motor 65.

[0022] like Figure 1 As shown, preferably, the bottom of the feed barrel 1 is fixedly connected to the side of the mixing bin 4 through the feed pipe 2, so as to reduce dust and raw material waste when feeding from above the mixing bin 4.

[0023] like Figure 1 As shown, preferably, a throttle valve 33 is provided on the negative pressure pipe 32, and the throttle valve 33 controls the air flow in the negative pressure pipe 32, thereby controlling the feeding speed.

[0024] like Figure 3 and Figure 4 As shown, preferably, the filter device 36 includes a filter plate socket 34 and a filter plate 35 , and the filter plate 35 can be inserted into the filter plate socket 34 .

[0025] like Figure 1As shown, preferably, a negative pressure gauge 46 is provided on the mixing chamber 4 to monitor the pressure in the mixing chamber 4 .

[0026] like Figure 1 As shown, preferably, a sealing cover 44 is provided at the discharge port 45 to ensure that the mixing chamber 4 is sealed when the fan 31 is running.

[0027] like Figure 2 As shown, preferably, the isolation cover 5 is provided with a first magnetic strip 51 and a second magnetic strip 52, and the isolation cover 5 is connected to the discharge port 44 and the receiving barrel 61 respectively through the first magnetic strip 51 and the second magnetic strip 52, and the magnetic strip connection is convenient for disassembly and installation.

[0028] like Figure 1 As shown, preferably, the second bracket 63 is provided with a lockable universal wheel 62 so that the material receiving bucket 61 can be moved and locked, which is convenient for workers to move the material receiving bucket 61.

[0029] like Figure 1 As shown, preferably, the second bracket 63 is fixedly connected to the first bracket 43 via a fixed connecting plate 66. Since the receiving barrel 61 is provided with a lockable universal wheel 62, even if the universal wheel 62 is lockable, the point contact with the ground is still not stable enough, so the first bracket 43 and the second bracket 63 are fixedly connected via a fixed connecting plate 66. The fixed connecting plate 66 is installed so that the receiving barrel 61 will not swing due to the centrifugal force generated when the second stirring device 64 rotates. The fixed connecting plate 66 can be a sheet metal part, and can also be fixedly connected to the first bracket 43 and the second bracket 63 via bolts.

[0030] Before loading graphite powder, check whether the sealing cover 44 at the discharge port 45 is covered, whether the filter plate 35 of the filter device 36 is inserted in the filter plate socket 34, and whether the fixed connecting plate 66 connecting the first bracket 43 and the second bracket 63 is loose. After the inspection is completed, the graphite powder enters the machine from the feed barrel 1. After the material is loaded, the machine is started, and the fan 31 works to extract air from the mixing chamber 4 to form a negative pressure in the mixing chamber 4. Since graphite powder is a lightweight powder, it is extracted into the mixing chamber 4 under the action of negative pressure. During the air extraction process, the powder may be extracted from the negative pressure pipe 32 into the fan 31, causing the fan 31 to lose and dust. Therefore, a filter device 36 is set. The filter device 36 includes a filter plate 35 and a filter plate socket 34. The filter plate 35 arranged on the filter plate socket 34 can filter the powder in the air of the mixing chamber 4. The throttle valve 33 arranged on the negative pressure pipe 32 can control the air circulation rate, thereby achieving the effect of controlling the feeding speed. The first motor 42 drives the first stirring device 41 to stir the graphite powder. During the operation of the machine, the pressure in the stirring bin 4 can be known through the negative pressure gauge 46 on the stirring bin 4. After the stirring is completed, the sealing cover 44 is removed, and the graphite powder is introduced into the receiving barrel 61. The dust caused during the introduction process will be blocked by the isolation cover 5. The graphite powder is temporarily stored in the receiving barrel 61. At this time, the second stirring device 64 set in the receiving barrel 61 is driven by the second motor 65 and rotates slowly, so that the graphite powder in the receiving barrel 61 is in a moving state, so that the graphite powder is not easy to agglomerate, and the graphite powder is mixed more evenly. The receiving barrel 61 can also be moved by the second bracket 63 to facilitate the transfer of materials. The present machine adopts negative pressure feeding, and the air in the mixing chamber is extracted by the fan 31, so that negative pressure is formed in the mixing chamber 4, and the graphite powder is sucked into the mixing chamber 4. The negative pressure will not cause excessive pressure on the chamber body, and at the same time prevent the possibility of leakage of graphite powder from the gap. Compared with the traditional feeding mechanism, such as the spiral feeding mechanism, the graphite powder can be quickly sucked into the mixing chamber 4, and the adhesion of the graphite powder in the pipeline will be greatly improved. At the same time, the traditional mixing machine will not take measures to prevent dust when receiving the material. The present machine is provided with an isolation cover 5 between the receiving barrel 61 and the discharge port 45. The isolation cover 5 is installed by a magnetic strip, and the cover body is a flexible non-porous material. The isolation cover 5 prevents dust and waste of raw materials, and is quick and easy to install with low cost. After receiving the graphite powder, a second stirring device 64 is also provided in the receiving barrel 61 to prevent the graphite powder from moving without agglomeration.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
