Description

Technical Field

[0001] The present invention relates to the technical field of graphite electrode processing, and particularly to a raw material kneader for graphite electrode processing provided with a quantitative feeding mechanism. Background Art

[0002] Graphite electrodes are important materials indispensable in industries such as electric arc furnace steelmaking and electrolytic aluminum. During the processing of graphite electrodes, raw materials such as graphite powder and asphalt need to be kneaded to form a paste with certain plasticity and viscosity for subsequent shaping processing.

[0003] For example, in the prior art, the patent with the publication number "CN218422528U" and the patent name "A Graphite Electrode Raw Material Kneading Device" discloses starting Motor 1, and Motor 1 drives Rotating Shaft 1 to rotate. The heater is turned on, and the heating rod electrically connected to the heater starts to heat. When the temperature is appropriate, Motor 2 is started, and Motor 2 drives Rotating Shaft 2 to rotate. The rotating plate on Rotating Shaft 2 starts to rotate. When the rotating plate rotates to different positions, the materials in the storage cylinder will fall from the discharge holes of different sizes. The discharge speed can be controlled by the discharge holes of different sizes. When there is more material in the mixing cylinder, a smaller-sized discharge hole can be used for discharging to avoid the accumulation of the same type of materials when there is more material, which affects the mixing between materials. At this time, the binder is added through the binder feeding port. The materials are in the mixing cylinder, and Rotating Shaft 1 drives the heating rod to stir and mix the materials. The scraper at the lower part of Rotating Shaft 1 can clean the materials adhered to the surface of the receiving funnel at the lower part of the mixing cylinder. The discharge valve is opened, and the materials enter the receiving box through the discharge port to complete the material receiving.

[0004] In the prior art, the patent with the publication number "CN118320711B" and the patent name "A Ratio Kneading Device for Graphite Electrode Production" discloses that the circulating material guiding mechanism includes a horizontal material conveying pipe and a vertical return pipe. A guiding spiral blade 1 is installed on the material conveying pipe. The upper side wall of the material conveying pipe is communicated with a feeding pipe, and the feeding pipe is used to communicate with the mixing layer. A guiding spiral blade 2 is installed on the return pipe. The upper end of the return pipe is installed with a discharge pipe communicated with the kneading box. A discharge pipe is connected to the material conveying pipe at the end far from the return pipe. When performing circulating material conveying, mixing, and kneading, the guiding spiral blade 1 conveys materials towards the return pipe direction. When the kneading is completed, the guiding spiral blade 1 conveys materials towards the discharge pipe direction for discharging. According to the ratio of the material types, a corresponding specification of the material conveying belt and the material port 2 are prepared. According to the quantity of the material types, a corresponding number of mixing layers are installed. According to the temperature requirement of the material mixing, the heating temperature of the temperature control pipe and the temperature control plate is adjusted. According to the material conveying integrity of the materials conveyed through the material hole 2, the material hole 1, and the mixing material conveying column channel, the material conveying rate is adjusted in cooperation with the pressure control pump.

[0005] When the raw material kneader in the above-mentioned prior art is in use, although it can prepare the corresponding feeding belt and the second material inlet according to the ratio of the material types to convey and proportion different materials, after multiple materials are proportioned, multiple groups of materials fall successively or simultaneously for kneading. In this way, the falling amount of different materials is the same at the same time, and thus it is impossible to carry out the feeding at a predetermined ratio while quantitatively feeding multiple materials. Therefore, the efficiency and quality of subsequent kneading will be affected. So, we propose a raw material kneader for graphite electrode processing provided with a quantitative feeding mechanism to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of the present invention is to provide a raw material kneader for graphite electrode processing provided with a quantitative feeding mechanism to solve the problems in the current market proposed in the above background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A raw material kneader for graphite electrode processing provided with a quantitative feeding mechanism, including a kneading chamber, and a base installed at the bottom of the kneading chamber. A moving frame is installed below the base. An upper cover body is connected above the kneading chamber, and kneading blades are installed through the interior of the lower part of the kneading chamber. Three feeding pipes are installed through the upper cover body at equal intervals. Three ratio control discs are installed inside the lower part of the upper cover body. The lower part of the ratio control disc is connected with a first feeding pipe, a second feeding pipe, and a third feeding pipe. The lower parts of the first feeding pipe, the second feeding pipe, and the third feeding pipe are connected with a quantitative control disc. The middle part of the quantitative control disc is connected to the upper cover body through a control rod. Three quantitative feeding ports are arranged at equal intervals inside the quantitative control disc.

[0008] Preferably, three through holes are opened inside the ratio control disc. One of the through holes corresponds to a feeding pipe above it. A first storage hopper, a second storage hopper, and a third storage hopper are installed in sequence inside the three through holes. The lower parts of the first storage hopper, the second storage hopper, and the third storage hopper are respectively connected with the first feeding pipe, the second feeding pipe, and the third feeding pipe.

[0009] Preferably, the diameter of the first feeding pipe is larger than that of the second feeding pipe, and the diameter of the second feeding pipe is larger than that of the third storage hopper.

[0010] Preferably, a rotating rod is fixed at the middle position of the ratio control disc. The upper end of the rotating rod penetrates the upper surface of the upper cover body. Three label plates are installed at equal intervals on the outer side of the upper end of the rotating rod.

[0011] Preferably, the lower parts of the first feeding pipe, the second feeding pipe, and the third feeding pipe are in fit connection with the upper surface of the quantitative control disc.

[0012] Preferably, the quantitative feeding port is arranged in an arc shape, and both the width and the arc length of the quantitative feeding port are greater than the diameter of the first feeding pipe.

[0013] Preferably, an arc-shaped material supporting plate is arranged in a groove inside the bottom surface of the kneading chamber. The side wall of the material supporting plate is in close contact with the inner side wall of the base. The bottom surface of the material supporting plate is connected to the base through a pressure-bearing spring, and a discharge pipe is fixedly penetrated through the bottom surface of the material supporting plate.

[0014] Preferably, "L"-shaped control frames are fixed below the left and right sides of the material supporting plate. Limit columns are installed in grooves on the left and right side surfaces of the base. The control frames are penetrated by the limit columns. A cross bar is fixed to the left side surface of the kneading chamber. A convex bar is installed on the outer side of the cross bar. The convex bar is arranged below the control frame, and the control frame forms a lifting structure through the convex bar.

[0015] Preferably, an inner pipe is slidably connected inside the lower part of the first feeding pipe. The lower part of the first feeding pipe is connected to the upper surface of the bottom pipe through a guide rod. The lower end of the inner pipe is inserted into the bottom pipe. The lowest point of the inner pipe is higher than the lowest point of the bottom pipe. An automatic control rod is fixed to the rear side surface of the inner pipe. Moving blocks are installed on the left and right side surfaces of the inner pipe. Guide rods are penetrated through the moving blocks. A return spring is nested on the outer side above the guide rods. Stirring rods are installed at equal intervals on the inner side wall of the inner pipe;

[0016] The first feeding pipe, the second feeding pipe and the third feeding pipe have the same structure.

[0017] Preferably, three groups of convex blocks are installed at equal intervals above the quantitative control disk. One side surface of the convex block is arranged in an arc shape. The lowest point of the automatic control rod is lower than the highest point of the convex block. The automatic control rod forms a lifting structure through the convex block.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: For the raw material kneading machine for graphite electrode processing provided with a quantitative feeding mechanism, while the first feeding pipe, the second feeding pipe or the third feeding pipe in the three groups can perform quantitative feeding on multiple materials, it can also control the quantitative feeding ratio of multiple different materials each time. Therefore, when performing quantitative feeding and kneading on multiple materials each time, the multiple materials are also in a fixed ratio. Thus, the multiple materials can be kneaded in a fixed ratio, thereby improving the uniformity, efficiency and quality of kneading. The specific content is as follows:

[0019] Three groups of first feeding tubes, second feeding tubes and third feeding tubes with different diameters are provided, and the first feeding tube, the second feeding tube or the third feeding tube in the three groups can be selected to be set correspondingly to the corresponding quantitative feeding port by rotating the ratio control disk, and the quantitative control disk is controlled to perform intermittent rotation for a certain period of time, so that the first feeding tube, the second feeding tube or the third feeding tube in the three groups can quantitatively feed a variety of materials, and the ratio of quantitative feeding of a variety of different materials each time can be controlled. Therefore, when quantitatively feeding and kneading a variety of materials each time, the various materials are also in a fixed ratio, so that the various materials can be mixed and kneaded at a fixed ratio, thereby improving the uniformity, efficiency and quality of mixing and kneading;

[0020] When the cross bar drives the convex rod to reciprocate clockwise and counterclockwise by 90°, a downward thrust can be intermittently applied to the control frame, so that the control frame cooperates with the stored force of the pressure spring to drive the support plate to reciprocate up and down and shake for a certain period of time, so that the support plate can sprinkle the material between the two sets of kneading blades upward, so that the two sets of kneading blades can knead the sprinkled material, thereby avoiding insufficient kneading of the logistics at the bottom of the kneading chamber, thereby achieving uniform kneading, ensuring sufficient contact and reaction of the raw materials, improving the plasticity and viscosity of the paste, and thus ensuring the uniformity and consistency of the graphite electrode;

[0021] When the first discharge pipe is separated from the corresponding quantitative discharge port and stops discharging, the cooperation between the protrusion and the automatic control rod drives the inner tube to move upward. Then, when the first discharge pipe coincides with the corresponding quantitative discharge port again, the accumulated force of the reset spring can automatically drive the inner tube and the toggle rod to move downward, thereby preventing the material from staying in the first discharge pipe for a long time and agglomerating, which affects its falling later.

DETAILED DESCRIPTION

[0034] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0035] See also Figures 1 - 11 , the present invention provides the following technical solutions:

[0036] Embodiment 1: The raw material kneading machine for graphite electrode processing provided with a quantitative feeding mechanism in this embodiment can feed a variety of different materials at a fixed ratio according to demand during the quantitative feeding process, thereby facilitating the subsequent fixed ratio kneading, so as to improve the uniformity, efficiency and quality of the coagulation. For the specific structure, refer to the attached Figures 1 - 8As shown in the figure, it includes a kneading chamber 1, and a base 2 installed at the bottom of the kneading chamber 1. A moving frame 3 is installed below the base 2. An upper cover 4 is connected above the kneading chamber 1. And a kneading paddle 8 is installed through the interior of the lower part of the kneading chamber 1. Three feeding pipes 5 are installed through the interior of the upper cover 4 at equal intervals. Three ratio control disks 10 are installed inside the lower part of the upper cover 4. A first blanking pipe 121, a second blanking pipe 131, and a third blanking pipe 141 are connected below the ratio control disk 10. The lower parts of the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141 are connected to a quantitative control disk 9. The middle part of the quantitative control disk 9 is connected to the upper cover 4 through a control rod 92. Three quantitative blanking openings 91 are arranged at equal intervals inside the quantitative control disk 9. Three through holes 11 are opened inside the ratio control disk 10. One of the through holes 11 corresponds to one feeding pipe 5 above. A first storage hopper 12, a second storage hopper 13, and a third storage hopper 14 are installed in sequence inside the three through holes 11. The lower parts of the first storage hopper 12, the second storage hopper 13, and the third storage hopper 14 are respectively connected to the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141. The diameter of the first blanking pipe 121 is larger than the diameter of the second blanking pipe 131, and the diameter of the second blanking pipe 131 is larger than the diameter of the third storage hopper 14.

[0037] A rotating rod 6 is fixed at the middle position of the ratio control disk 10. The upper end of the rotating rod 6 penetrates through the upper surface of the upper cover 4. Three label plates 61 are installed at equal intervals on the outer side of the upper end of the rotating rod 6. The lower parts of the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141 are in fit connection with the upper surface of the quantitative control disk 9. The quantitative blanking openings 91 are arranged in an arc shape. The width and arc length of the quantitative blanking openings 91 are both larger than the diameter of the first blanking pipe 121. An arc-shaped material supporting plate 7 is arranged in a groove inside the bottom surface of the kneading chamber 1. The side wall of the material supporting plate 7 is in fit contact with the inner side wall of the base 2. The bottom surface of the material supporting plate 7 is connected to the base 2 through a pressure-bearing spring 201. A discharge pipe 71 is fixedly installed through the bottom surface of the material supporting plate 7. "L"-shaped control frames 72 are fixedly installed on both the left and right sides below the material supporting plate 7. Limit posts 202 are installed in grooves on both the left and right side surfaces of the base 2. The control frames 72 and the limit posts 202 are arranged in a penetrating manner. A cross bar 15 is fixed on the left side surface of the kneading chamber 1. A convex bar 151 is installed on the outer side of the cross bar 15. The convex bar 151 is arranged below the control frame 72. The control frame 72 forms a lifting structure through the convex bar 151.

[0038] Move the entire raw material kneading machine into the working area. Since the three label plates 61 on the outer side of the rotating rod 6 are sequentially marked as large pipe, medium pipe, and small pipe, directly below the label plate 61 marked as large pipe is the first blanking pipe 121, directly below the label plate 61 marked as medium pipe is the second blanking pipe 131, and directly below the label plate 61 marked as small pipe is the third blanking pipe 141. Therefore, the staff can rotate the corresponding rotating rod 6 according to the ratio between different materials, so that the rotating rod 6 drives the ratio control disk 10 to rotate. Thus, the first blanking pipe 121, the second blanking pipe 131, or the third blanking pipe 141 below the ratio control disk 10 can be rotated to the position above the corresponding quantitative blanking port 91. Then, different materials are respectively poured into the three feeding pipes 5, and then fall into the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141 through the first storage hopper 12, the second storage hopper 13, and the third storage hopper 14 respectively. At this time, connect the control rod 92 to an external motor, and the motor drives the control rod 92 and the quantitative control disk 9 to rotate. At this time, the three groups of quantitative blanking ports 91 on the quantitative control disk 9 are rotated to directly below the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141. Then, the materials in the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141 fall into the kneading chamber 1 through the quantitative blanking ports 91. Thus, according to the first blanking pipe 121, the second blanking pipe 131, or the third blanking pipe 141 with different diameters, different materials are blanked later, so that within a certain period of time, the different materials falling down show a fixed ratio. At the same time, start the motor on the left side of the kneading chamber 1 to drive the kneading blades 8 to rotate. At this time, the kneading blades 8 can knead a variety of materials at a fixed ratio, thereby improving the uniformity, efficiency, and quality of kneading.

[0039] After blanking simultaneously for a period of time, rotate the control rod 92 and the quantitative control disk 9 in the reverse direction, so that the quantitative blanking ports 91 are separated from the first blanking pipe 121, the second blanking pipe 131, and the third blanking pipe 141. Therefore, the blanking is temporarily stopped first. By operating in this way repeatedly, intermittent quantitative blanking can be carried out, avoiding the situation that the materials accumulate together during continuous blanking and affecting the kneading efficiency.

[0040] Meanwhile, connect the left end of the cross bar 15 to an external motor. The motor drives the cross bar 15 to rotate clockwise by 90°. At this time, the cross bar 15 drives the convex bar 151 to rotate and press the control frame 72 downward. At this time, the control frame 72 slides outside the limit post 202. At the same time, the control frame 72 drives the material supporting plate 7 to move downward. Then the pressure-bearing spring 201 is compressed and stores energy. Then the motor drives the cross bar 15 to rotate counterclockwise by 90° to reset. At this time, the convex bar 151 is separated from the control frame 72. The energy stored in the pressure-bearing spring 201 automatically drives the material supporting plate 7 to move upward and reset. By repeating such operations, the material supporting plate 7 can drive part of the materials to perform reciprocating lifting and shaking, and part of the materials can be splashed upward, so that the kneading blades 8 can uniformly knead the materials at the bottom of the kneading chamber 1, avoiding insufficient kneading. Therefore, it can ensure the full contact and reaction of the raw materials, improve the plasticity and viscosity of the paste, and thus ensure the uniformity and consistency of the electrode blank, so as to improve the kneading efficiency and quality of the raw material kneading machine. The elastic force of the pressure-bearing spring 201 is greater than the gravity of the materials above the material supporting plate 7. Therefore, the gravity of the materials will not cause the material supporting plate 7 to descend.

[0041] Embodiment 2: The raw material kneading machine for processing graphite electrodes with a quantitative feeding mechanism in this embodiment can avoid the caking of heavy materials piled up together during intermittent feeding, which affects the subsequent feeding operation on the basis of Embodiment 1. The specific structure is as shown in the attached Figures 9 - 11 figure. A inner tube 122 is slidably connected inside the lower part of the first feeding tube 121. The lower part of the first feeding tube 121 is connected to the upper surface of the bottom tube 123 through a guide rod 127. The lower end of the inner tube 122 is inserted into the bottom tube 123. The lowest point of the inner tube 122 is higher than the lowest point of the bottom tube 123. A self-control rod 124 is fixed on the rear side surface of the inner tube 122. Moving blocks 126 are installed on the left and right side surfaces of the inner tube 122. A guide rod 127 penetrates through the inside of the moving block 126. A return spring 128 is nested outside the upper part of the guide rod 127. Stirring rods 125 are installed at equal intervals on the inner side wall of the inner tube 122. The structures of the first feeding tube 121, the second feeding tube 131 and the third feeding tube 141 are the same. Three groups of convex blocks 93 are installed at equal intervals above the quantitative control disk 9. One side surface of the convex block 93 is arc-shaped. The lowest point of the self-control rod 124 is lower than the highest point of the convex block 93. The self-control rod 124 forms a lifting structure through the convex block 93.

[0042] When the control rod 92 and the quantitative control disk 9 are rotated in the opposite direction, the quantitative discharge port 91 is separated from the first discharge tube 121, the second discharge tube 131 and the third discharge tube 141, and the discharge is temporarily stopped at this time, the remaining materials are accumulated in the first discharge tube 121, the second discharge tube 131 and the third discharge tube 141. At the same time, the first discharge tube 121, the second discharge tube 131 and the third discharge tube 141 in this embodiment have the same structure. At this time, the automatic control rod 124 on the outside of the inner tube 122 in the first discharge tube 121, the second discharge tube 131 and the third discharge tube 141 is pushed upward by the protrusion 93, and the automatic control rod 124 drives the inner tube 122 to move upward. At this time, the inner The moving block 126 on the outside of the tube 122 slides on the outside of the guide rod 127, and at the same time squeezes and accumulates force on the reset spring 128. When the control rod 92 and the quantitative control disk 9 are rotated in the forward direction, the three groups of quantitative discharge ports 91 correspond to the first discharge tube 121, the second discharge tube 131 and the third discharge tube 141. At this time, the automatic control rod 124 is separated from the protrusion 93, so the force accumulated by the reset spring 128 can automatically drive the inner tube 122 and the toggle rod 125 to move downward and reset. At this time, the inner tube 122 and the toggle rod 125 are used in combination to make the material in the first discharge tube 121 fall well, avoiding the material from being agglomerated in the first discharge tube 121 for a long time and affecting the later falling work.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
