Description

Technical Field

[0001] The invention relates to the technical field of graphite electrode processing, in particular to a raw material kneading machine for graphite electrode processing which is provided with a quantitative feeding mechanism. Background Art

[0002] Graphite electrodes are an indispensable and important material in industries such as electric furnace steelmaking and electrolytic aluminum. During the processing of graphite electrodes, graphite powder, asphalt and other raw materials need to be mixed and kneaded to form a paste with certain plasticity and viscosity for subsequent molding processing; For example, the patent name disclosed by the announcement number "CN218422528U" in the prior art is "a graphite electrode raw material kneading device", which discloses starting motor one, motor one drives shaft one to rotate, turning on the heater, and the heating rod electrically connected to the heater starts to heat. When the temperature is appropriate, start motor two, motor two drives shaft two to rotate, and the rotating plate on shaft two starts to rotate. When the rotating plate rotates to different positions, the material in the storage barrel will fall from the discharge holes of different sizes, and the discharge speed can be controlled by the discharge holes of different sizes. When there are more materials in the mixing drum, a smaller discharge hole can be used for discharge to avoid the accumulation of the same type of materials when there are more materials, which affects the mixing of the materials. At this time, the adhesive is added through the adhesive feeding port. The material is in the mixing drum, and the shaft one drives the heating rod to stir and mix the material. The scraper at the lower part of the shaft can clean the material adhered to the surface of the receiving funnel at the lower part of the mixing drum, and the discharge valve is opened. The material enters the receiving box through the discharge port to complete the collection. The patent title disclosed in the prior art with the announcement number "CN118320711B" is "A Proportioning and Kneading Device for Graphite Electrode Production", which discloses that the circulating material guiding mechanism includes a horizontal material conveying pipe and a vertical return pipe, a material conveying screw blade 1 is installed on the material conveying pipe, a material discharge pipe is connected to the upper side wall of the material conveying pipe, and the material discharge pipe is used to connect the mixing layer, a material conveying screw blade 2 is installed on the return pipe, a discharge pipe connected to the kneading box is installed at the upper end of the return pipe, and a discharge pipe is connected to the material conveying pipe away from one end of the return pipe. During the circulating material transfer, mixing and kneading, the material guide screw blade transfers the material in the direction of the reflux pipe. After the kneading is completed, the material guide screw blade transfers the material in the direction of the discharge pipe. According to the ratio of the material types, prepare the corresponding specifications of the transfer belt and material port 2. According to the number of material types, install the corresponding number of mixing layers. According to the temperature requirements of the material mixing, adjust the heating temperature of the temperature control tube and the temperature control plate. According to the material transfer integrity of the material hole 2, the material hole 1 and the mixed material transfer column, cooperate with the pressure control pump to adjust the material transfer rate.

[0003] When the raw material kneading machine in the above-mentioned prior art is used, although the corresponding specifications of the conveyor belt and the material port can be prepared according to the ratio of the material types to convey different materials in different ratios, after the multiple materials are proportioned, multiple groups of materials are dropped in sequence or simultaneously for kneading, which makes the falling amount of different materials the same at the same time, and then the multiple materials cannot be fed at a predetermined ratio at the same time during the quantitative feeding process, which affects the efficiency and quality of the subsequent kneading. Therefore, we propose a raw material kneading machine for graphite electrode processing with a quantitative feeding mechanism to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

The ratio control disk 10 is provided with three groups of through holes 11, one of which has a corresponding injection pipe 5 above it, and the first storage hopper 12, the second storage hopper 13 and the third storage hopper 14 are installed in sequence inside the three groups of through holes 11, and the first storage hopper 12, the second storage hopper 13 and the third storage hopper 14 are connected to the first discharge pipe 121, the second discharge pipe 131 and the third discharge pipe 141 below them respectively, the diameter of the first discharge pipe 121 is larger than the diameter of the second discharge pipe 131, and the diameter of the second discharge pipe 131 is larger than the diameter of the third storage hopper 14.

[0020] A rotating rod 6 is fixed at the middle position of the ratio control disk 10, and the upper end of the rotating rod 6 passes through the upper surface of the upper cover body 4. Three groups of 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 discharge pipe 121, the second discharge pipe 131 and the third discharge pipe 141 are fitted and connected with the upper surface of the quantitative control disk 9. The quantitative discharge port 91 is arranged in an arc shape, and the width and arc length of the quantitative discharge port 91 are greater than the diameter of the first discharge pipe 121. The bottom surface of the kneading chamber 1 is grooved with an arc-shaped supporting plate 7, and the side wall of the supporting plate 7 is connected to the inner wall of the base 2. The side walls are in close contact, the bottom surface of the supporting plate 7 is connected to the base 2 through a pressure spring 201, a discharge pipe 71 is fixed through the bottom surface of the supporting plate 7, a control frame 72 with an "L" shaped structure is fixed below the left and right sides of the supporting plate 7, and the left and right sides of the base 2 are grooved to install limit columns 202, the control frame 72 and the limit columns 202 are arranged through, a cross bar 15 is fixed to the left side of the kneading chamber 1, a convex rod 151 is installed on the outer side of the cross bar 15, and a control frame 72 is arranged below the convex rod 151, and the control frame 72 forms a lifting structure through the convex rod 151.

[0021] The entire raw material kneading machine is moved into the working area. Since the three label plates 61 on the outer side of the rotating rod 6 are marked as large tube, medium tube and small tube respectively, the first discharge tube 121 corresponds to the label plate 61 marked as large tube, the second discharge tube 131 corresponds to the label plate 61 marked as medium tube, and the third discharge tube 141 corresponds to the label plate 61 marked as small tube. 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, thereby rotating the first discharge tube 121, the second discharge tube 131 or the third discharge tube 141 under the ratio control disk 10 to the upper position of the corresponding quantitative discharge port 91, and then pour different materials into the three injection tubes 5 respectively, and then fall into the first discharge tube 1 through the first storage hopper 12, the second storage hopper 13 and the third storage hopper 14 respectively. 21. In the second feeding tube 131 and the third feeding tube 141, the control rod 92 is connected to the 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 feeding ports 91 on the quantitative control disk 9 are rotated to the bottom of the first feeding tube 121, the second feeding tube 131 and the third feeding tube 141, and then the materials in the first feeding tube 121, the second feeding tube 131 and the third feeding tube 141 fall into the kneading chamber 1 through the quantitative feeding ports 91. Therefore, different materials are discharged according to the first feeding tube 121, the second feeding tube 131 or the third feeding tube 141 with different diameters in the later stage, so that different materials falling within a certain period of time are in a fixed ratio. At the same time, the motor on the left side of the kneading chamber 1 is started to drive the kneading blade 8 to rotate. At this time, the kneading blade 8 can knead a variety of materials at a fixed ratio, thereby improving the uniformity, efficiency and quality of kneading.

[0022] After a period of time of discharging, the control rod 92 and the quantitative control disk 9 are rotated in the opposite direction to separate the quantitative discharging port 91 from the first discharging pipe 121, the second discharging pipe 131 and the third discharging pipe 141, so that the discharging is temporarily stopped. The operation is repeated in this way to perform intermittent quantitative discharging, so as to avoid the continuous discharging of materials from piling up and affecting the mixing efficiency.

[0023] At the same time, the left end of the cross bar 15 is connected to the external motor, and the motor drives the cross bar 15 to rotate 90° clockwise. At this time, the cross bar 15 drives the convex rod 151 to rotate and press the control frame 72 downward. At this time, the control frame 72 slides on the outside of the limit column 202. At the same time, the control frame 72 drives the supporting plate 7 to move downward, and then the pressure spring 201 is squeezed and force is accumulated. Then the motor drives the cross bar 15 to rotate 90° counterclockwise to reset. At this time, the convex rod 151 is separated from the control frame 72, and the supporting plate 7 is automatically driven to move upward and reset through the stored force of the pressure spring 201. Such repeated operations can make the supporting plate 7 drive part of the material to perform reciprocating lifting and shaking, and can sprinkle part of the material upward, so that the kneading blades 8 can evenly knead the material in the bottom of the kneading chamber 1 to avoid insufficient kneading, thereby ensuring sufficient contact and reaction of the raw materials, improving the plasticity and viscosity of the paste, thereby ensuring the uniformity and consistency of the electrode body, thereby improving the kneading efficiency and quality of the raw material kneading machine, and the elastic force of the pressure spring 201 is greater than the gravity of the material above the supporting plate 7, so the gravity of the material will not cause the supporting plate 7 to fall.

[0024] Embodiment 2: The raw material kneading machine for graphite electrode processing provided with a quantitative feeding mechanism in this embodiment can avoid the accumulation and agglomeration of heavier materials during intermittent feeding, thereby affecting the subsequent feeding operation. The specific structure is shown in the attached Figure 9-11 As shown, the lower interior of the first feeding tube 121 is slidably connected with an inner tube 122, the lower interior 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, the rear side of the inner tube 122 is fixed with an automatic control rod 124, the left and right sides of the inner tube 122 are both installed with moving blocks 126, and the interior of the moving block 126 is penetrated by a guide rod 127. 27. A return spring 128 is nested and connected to the outer side of the upper side of the guide rod 127. A toggle rod 125 is installed at equal intervals on the inner wall of the inner tube 122. The first discharge tube 121, the second discharge tube 131 and the third discharge tube 141 have the same structure. Three groups of protrusions 93 are installed at equal intervals above the quantitative control disk 9. One side of the protrusion 93 is arranged in an arc shape. The lowest point of the automatic control rod 124 is lower than the highest point of the protrusion 93. The automatic control rod 124 forms a lifting structure through the protrusion 93.

[0025] 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.

[0026] 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.
