DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

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

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of the present invention proposes: a calcined coke powder batching mechanism for raw anode manufacturing, comprising a batching tank 1, a feeder 2 and a stirring member 3, a delivery pipe 102 arranged at the lower part of the batching tank 1 is provided with a feeder pipe 104, a propeller blade 105 is arranged in the delivery pipe 102, after the material in the batching tank 1 is stirred and mixed, the material can be transported to the processing equipment of the next process through the cooperation of the delivery pipe 102 and the feeder pipe 104, and a feeder 2 is arranged on the tank cover 101 at the upper part of the batching tank 1, a feeder nozzle 202 at the lower part of the hopper 201 of the feeder 2 passes through the tank cover 101 and extends into the internal cavity of the batching tank 1, and a blocking plate 204 arranged at the lower part of the feeder nozzle 202 is fixedly connected to the toggle rod 206 through a transmission rod 205 A spring plate 208 is arranged on the connecting shaft 2041 between the sealing plate 204 and the discharge nozzle 202, so as to push the toggle rod 206 during the stirring process, so that the toggle rod 206 deflects at the lower part of the discharge nozzle 202 with the sealing plate 204 through the transmission rod 205, and the sealing plate 204 is misaligned with the lower port of the discharge nozzle 202, and the material leaks from the misaligned position to complete the addition of the material, and a stirring member 3 is arranged in the internal cavity of the batching tank 1, and the stirring plate 301 of the stirring member 3 is arranged at the bottom of the internal cavity of the batching tank 1, and the stirring plate 301 is connected to the second motor 302 through the transmission shaft 303, ensuring that the second motor 302 drives the stirring plate 301 to rotate in the tank body to stir the material so that the material is fully mixed together.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, a retaining ring 203 that abuts against the upper surface of the tank cover 101 is provided on the outer wall of the connection portion between the hopper 201 and the discharge nozzle 202, and the discharge nozzle 202 is inserted into the through hole opened at the corresponding position on the tank cover 101, ensuring that the entire adding piece 2 is stably installed on the tank cover 101, so that the material can be added into the tank body during use to complete the addition of the material. The number of adding pieces 2 is set according to actual usage requirements, and the upper end of the connecting shaft 2041 on the sealing plate 204 is rotatably connected to the shaft seat 2021 integrally provided on the outer wall of the lower end of the discharge nozzle 202, ensuring that the sealing plate 204 is stably installed at the lower port position of the discharge nozzle 202 to seal it and ensure that the material is smoothly stored in the hopper. 201, it is ensured that under the driving action of external force, the blocking plate 204 can be deflected at the lower part of the discharge nozzle 202 through the connecting shaft 2041, so that the blocking plate 204 is dislocated from the lower port of the discharge nozzle 202, so that the material can fall into the tank body from the dislocated position, and the material addition is completed, and the spring plate 208 is fixedly connected to the connecting shaft 2041 through the ring sleeve integrally arranged at the middle part, and both ends of the spring plate 208 are in contact with the outer wall of the discharge nozzle 202, so that the spring plate 208 can be stably installed on the connecting shaft 2041, so that during the deflection of the blocking plate 204, the spring plate 208 produces appropriate deformation with the rotation of the connecting shaft 2041, so that when the blocking plate 204 loses the external force driving, it can bring the blocking plate 204 back to its original position;

[0028] A stopper 2051 is integrally provided on the transmission rod 205 at the lower part of the blocking plate 204, and a scale line cooperating with the indicator plate 2064 on the toggle rod 206 is provided at the edge of the stopper 2051, so that the position of the toggle rod 206 can be accurately adjusted on the transmission rod 205 by using the cooperation between the two, so as to realize the debugging operation of the effective contact distance between the toggle rod 206 and the toggle plate 3011, wherein, when the toggle plate 3011 initially contacts the toggle rod 206, the effective contact distance between the two is the largest, and as the plate body rotates to push the rod body to move, the effective contact distance between the rod body and the plate body is increased. The contact distance gradually decreases until the two are completely separated. The larger the effective contact distance between the two, the greater the misalignment between the driving blocking plate 204 and the lower end of the discharge nozzle 202. In this way, the setting of the discharge amount of the adding member 2 can be completed, so that each adding member 2 can be set according to the ratio of different materials. There is no need to weigh or perform other quantitative operations during the process of adding materials to the tank body, which improves efficiency. As the materials are stirred and mixed, the materials are slowly added to the tank body. Compared with the one-time material addition, the materials can be stirred and mixed together faster, with high speed and efficiency.

[0029] The lower end of the transmission rod 205 is slidably inserted into the connecting sleeve 2061 provided at one end of the toggle rod 206, so that the toggle rod 206 can be stably installed on the transmission rod 205, and a stable connection between the two can be achieved, and it can be ensured that the toggle rod 206 can be smoothly rotated and adjusted on the transmission rod 205 through the connecting sleeve 2061. The upper part of the connecting sleeve 2061 abuts against the stopper 2051, and the lower part abuts against the limiting nut 207 threadedly connected to the lower end of the transmission rod 205, so as to limit it and prevent the connecting sleeve 2061 from sliding off the transmission rod 205, thereby ensuring stable use.

[0030] The side wall of the connecting sleeve 2061 is integrally provided with a threaded sleeve 2062, and the threaded sleeve 2062 is threadedly connected to the limiting screw 2063, and one end of the limiting screw 2063 is bent to form a driving rod, which is convenient for hand-operated to drive the limiting screw 2063 and ensure smooth use. The end of the threaded section of the limiting screw 2063 passes through the through hole opened at the corresponding position on the connecting sleeve 2061 and contacts the transmission rod 205, which is convenient for stably installing the limiting screw 2063 on the connecting sleeve 2061. The connecting sleeve 2061 and the toggle rod 206 do not interfere with the transmission rod 205, and the connecting sleeve 2061 and the toggle rod 206 are fixed and limited on the transmission rod 205 to achieve a stable connection between the two. When the position of the toggle rod 206 needs to be adjusted, the limit screw 2063 is directly driven by hand to cancel the limit fixation of the connecting sleeve 2061, and then the toggle rod 206 is rotated on the transmission rod 205 through the connecting sleeve 2061. After the position debugging is completed, the limit screw 2063 is rotated to interfere with the transmission rod 205, thereby completing the fixed limit of the toggle rod 206 and ensuring stable use.

[0031] like Figure 2 and Figure 4As shown, in some embodiments, the stirring plate 301 is fixedly connected to the lower end of the transmission shaft 303, the upper end of the transmission shaft 303 passes through the tank cover 101 and is fixedly connected to the output shaft of the second motor 302, the transmission shaft 303 is rotatably connected to the tank cover 101, and the second motor 302 is fixedly connected to the upper part of the tank cover 101, so that when it is necessary to stir the material inside the tank body, the second motor 302 is started, and the second motor 302 drives the stirring plate 301 to rotate inside the tank body through the transmission shaft 303, so as to stir and mix the material put into the tank body so that the material is fully mixed together, and the stirring plate 301 is a spirally twisted arc plate and is distributed in a ring array, and the lower part of the stirring plate 301 is provided with equally spaced material picking teeth 3012, which rotate together with the plate body in the tank body, and when the material is stirred, part of the material can be pulled out from the two The stirring plate 301 is provided with a through-type leakage slot 3013. During the stirring process, part of the material pushed by the plate body leaks out from the leakage slot 3013, thereby enhancing the efficiency of material disturbance and stirring. In addition, a toggle plate 3011 is provided on the upper part of one end of the stirring plate 301 that contacts the inner wall of the batching tank 1. The upper end height of the toggle plate 3011 is higher than the height of the toggle rod 206 inside the tank body. The toggle plate 3011 moves inside the tank body together with the plate body, and during the movement, the toggle rod 206 at the lower part of the feed piece 2 is toggled, so that the blocking plate 204 at the lower part of the feed piece 2 is moved away from the lower part of the discharge nozzle 202, so that the material is smoothly discharged from the discharge nozzle 202 into the tank body, thereby completing the addition of the material.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the leakage port provided at the bottom of the batching tank 1 is connected to one end of the conveying pipe 102 through a pipeline, so that the material stirred and mixed inside the tank body can be guided to the conveying pipe 102 through the cooperation of the leakage port and the pipeline during use, ensuring smooth discharge of the tank body, and an auxiliary part 106 is arranged at the leakage port, so that when the material is stirred inside the tank body, the leakage port at the bottom of the tank body is blocked to ensure that the unstirred material enters the conveying pipe 102, thereby improving the quality of the batching, and the propeller blade 105 arranged inside the conveying pipe 102 is connected to the first motor 103 through a shaft, and the first motor 103 is fixedly connected to one end of the conveying pipe 102 located at the discharge pipe 104, ensuring that the first motor 103 is stably installed, and stably outputs power during operation, drives the propeller blade 105 to rotate inside the conveying pipe 102, and pushes the material dropped from the batching tank 1 to the position of the discharge pipe 104, thereby transmitting it to the production equipment of the next process;

[0033] The baffle 1061 of the auxiliary component 106 is placed at the leakage port at the bottom of the batching tank 1 and is arranged in coordination with the leakage port to facilitate the stable sealing of the leakage port to prevent the material from leaking into the conveying pipe 102 during the mixing process. The lower end of the connecting rod 1062 at the lower part of the baffle 1061 is fixedly connected to the sliding bracket 1063, and the sliding bracket 1063 is slidably connected in the pipeline between the batching tank 1 and the conveying pipe 102 to ensure that when the sliding bracket 1063 slides in the pipeline, the baffle 1061 moves together through the connecting rod 1062, and the lower part of the sliding bracket 1063 passes through the connection part between the pipeline and the conveying pipe 102 and extends into the internal cavity of the conveying pipe 102, so that when the propeller blade 105 rotates in the conveying pipe 102, the propeller blade The edge of 105 will push the bottom of the sliding bracket 1063, so that the sliding bracket 1063 slides upward in the pipeline, and the baffle 1061 is driven to separate from the leakage port through the connecting rod 1062, so that the mixed material enters the pipeline and falls into the conveying pipe 102. When the propeller blade 105 cancels the push on the sliding bracket 1063, under the action of the material and its own gravity, the entire auxiliary component 106 moves downward, and the baffle 1061 blocks the leakage port again. In this way, the material is intermittently and stably conveyed into the conveying pipe 102, which can well control the feed amount and feed speed. The single feed amount can be controlled by the lifting height of the baffle 1061, and the speed can be controlled by the rotation speed of the propeller blade 105.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
