Description
Technical Field
[0001] The present application belongs to the technical field of electrode paste production equipment, and in particular relates to a double stirring kneading pot uniform feeding device. Background Art
[0002] The production process of electrode paste mainly involves mixing and stirring dry materials such as graphite and coal used for conductivity and wet materials such as medium-temperature asphalt used as a binder in strict proportion into a homogeneous paste, and then forming blocks through compression molding, demoulding, and cooling to be used as electrodes in a submerged arc furnace. During the kneading process, a kneading pot is required to mix and stir the materials. Whether the kneading pot can fully play its role in stirring and mixing determines the quality of the finished electrode paste.
[0003] In the prior art, a double stirring kneading pot is used. The kneading pot is designed with upper and lower layers. A reamer is arranged inside each layer. Dry materials are added to the upper layer for dry mixing, and wet materials are added to the lower layer for heat preservation. After both materials meet the process requirements, they are fully mixed and stirred to obtain a uniform electrode paste. Since the upper layer feeding process is carried out in a non-sealed structure, the following problems are prone to occur: dry materials are prone to local accumulation in the upper layer. If the dry materials are accumulated too high, they are prone to pop out or block the feed port of the upper layer, causing material loss or reducing the feeding efficiency; the accumulation of dry materials causes uneven distribution of materials in the upper layer, and it is easy to form a hardened layer, which prolongs the mixing time and aggravates the wear of the reamer and the inner lining of the kneading pot. Summary of the invention

[0024] The following is combined with Figure 1 To Attachment Figure 5 And specific embodiments further describe the present application in detail.
[0025] In the present application, a double stirring kneading pot uniform feeding device is disclosed, which comprises a screw feeder 10, a double-layer kneading pot 20 and a feeding chamber 30, wherein the feeding chamber 30 is covered and arranged on the upper layer of the double-layer kneading pot 20, and the side of the feeding chamber 30 away from the double-layer kneading pot 20 is connected to the discharge end of the above-mentioned screw feeder 10, and a baffle 31 is arranged between the feeding chamber 30 and the double-layer kneading pot 20, and a plurality of feeding holes 311 are arranged on the baffle 31, and the feeding chamber 30 is provided with a plurality of feeding holes 311. The material hole 311 connects the material discharge chamber 30 with the interior of the double-layer kneading pot 20; a first driving shaft 32 is rotatably provided on the top wall of the material discharge chamber 30, the axis of the first driving shaft 32 is located at the contour center of the upper surface of the baffle 31, and a material shifting rod 321 is provided at one end of the first driving shaft 32 adjacent to the baffle 31, at least one side of the material shifting rod 321 is slidably in contact with the baffle 31, and the material shifting rod 321 is used to shift the dry material into the double-layer kneading pot 20 through the material discharge hole 311.
[0026] Specifically, the discharge port of the screw feeder 10 is connected to the upper side of the discharge chamber 30; a first drive motor 322 is provided on the top wall of the discharge chamber 30, and the rotating shaft of the first drive motor 322 is transmission-connected with the first drive shaft 32 for driving the feed rod 321 to rotate.
[0027] The use of the above-mentioned double stirring kneading pot uniform feeding device can achieve at least the following technical effects:
[0028] After the dry material is fed into the discharge chamber 30 by the screw feeder 10, the dry material is driven to enter the double-layer kneading pot 20 through the discharge hole 311 on the baffle plate 31 under the rotation of the material-displacing rod 321 in a dispersed and uniform manner, thereby avoiding the problem of a large amount of dry material being piled up too high in a local area of the upper layer of the double-layer kneading pot 20, resulting in material loss or reduced discharge efficiency; after the dry material is dispersed and dropped from the edge of the baffle plate 31 and the discharge port to the double-layer kneading pot 20, the problem of uneven distribution and compaction is avoided, and the dry material and the wet material can be mixed more easily, which reduces the stirring and mixing time to a certain extent and slows down the wear of the reamer and the inner lining of the double-layer kneading pot 20.
[0029] In addition, the present application also provides some more specific implementation methods to improve the above-mentioned double stirring kneading pot uniform feeding device. Example
[0030] Furthermore, in order to prevent the dry materials from accumulating on the upper part of the baffle plate 31, the length of the material-moving rod 321 is not less than the maximum distance from the center of the contour to the edge of the contour of the upper surface of the baffle plate 31. The material-moving rod 321 can drive the dry materials on the baffle plate 31 to the maximum extent during the rotation process, so that the dry materials enter the double-layer kneading pot 20 from the edge of the baffle plate 31 and the discharge hole 311.
[0031] Furthermore, in order to improve the efficiency of the dry material entering the double-layer kneading pot 20 under the push of the material-moving rod 321, the material-moving rod 321 includes an arc-shaped rod, and the side surface of the arc-shaped rod perpendicular to the baffle 31 is an arc-shaped surface, and the arc-shaped surface is a convex arc surface, and the rotation direction of the first drive shaft 32 is consistent with the convex direction of the convex arc surface.
[0032] When the above device is used, the first driving motor 322 drives the arc rod to rotate in the direction where the arc surface convexes. During the rotation of the arc rod, the convex arc surface thereof scrapes the baffle plate 31 and drives away the dry materials on the baffle plate 31, so that the dry materials that have not had time to fall off the double-layer kneading pot 20 from the discharge hole 311 move toward the outside of the baffle plate 31 along the arc line of the convex arc surface. Under the action of the material moving rod 321, a part of the dry materials are thrown down from the gap between the side of the baffle plate 31 and the inner wall of the double-layer kneading pot 20, which not only improves the efficiency of the dry materials entering the double-layer kneading pot 20, but also further avoids the local accumulation of the dry materials in the double-layer kneading pot 20, so that the dry materials are evenly distributed.
[0033] Furthermore, in order to improve the uniformity of the distribution of the dry material on the baffle 31, the first drive shaft 32 is rotatably sleeved with a second drive shaft 33 at one end adjacent to the screw feeder 10, and a plurality of fins 331 are circumferentially arranged at one end of the second drive shaft 33 for dispersing the dry material.
[0034] Specifically, the second drive shaft 33 is a hollow shaft with an inner diameter larger than the outer diameter of the first drive shaft. The second drive shaft 33 is mounted on the upper end of the first drive shaft 32 through a bearing sleeve, and the upper end of the second drive shaft 33 is connected to the second drive motor 332 through a bevel gear set. The second drive motor 332 is used to drive the second drive shaft 33 to rotate the vane 331, and the rotation speed of the second drive shaft 33 is higher than the rotation speed of the first drive shaft 32.
[0035] When the above device is used, after the dry material is fed into the discharge chamber 30 by the screw feeder 10 and before reaching the baffle 31, it is broken up by the high-speed rotating vanes 331, making the dry material particles more discrete, thereby improving the efficiency of the dry material entering the double-layer kneading pot 20 through the discharge port.
[0036] Furthermore, in order to avoid congestion when the dry material passes through the discharge hole 311, the baffle 31 is connected to the inner wall of the discharge chamber 30 through an elastic connecting member 312 such as a spring or an elastic telescopic rod.
[0037] When the material removing rod 321 continuously scrapes the upper surface of the baffle 31 during rotation, the baffle 31 vibrates at a low frequency under the action of the elastic connecting member 312 and generates vibrations to the dry material, thereby preventing the dry material from being blocked at the discharge port and improving the efficiency of the dry material passing through the discharge port. Example
[0038] Based on part of the first embodiment, the second embodiment is different in that:
[0039] The material-moving rod 321 is a fan-shaped paddle 324 , the cross section of which is fan-shaped, and the side of the fan-shaped paddle 324 facing away from the baffle 31 is a conical surface.
[0040] Specifically, the fan-shaped paddle 324 is regarded as a cut-off portion of the bottom of a cone. The fan-shaped paddle 324 can block a portion of the discharge hole 311 during rotation, so that the dry material can fall into the double-layer kneading pot 20 through the unblocked discharge hole 311, thereby avoiding a large amount of dry material from accumulating on the baffle 31, and improving the efficiency of the dry material passing through the discharge hole 311; and because the side of the fan-shaped paddle 324 facing away from the baffle 31 is a cone, the fan-shaped paddle 324 can easily make the dry material on the fan-shaped paddle 324 slide downward along the generatrix during rotation, and fall into the double-layer kneading pot 20 from the edge of the baffle 31, thereby improving the uniformity of the distribution of the dry material in the double-layer kneading pot 20.
[0041] Furthermore, in order to replace the effect achieved by the wing 331 in the first embodiment, a dry material dispersing portion 323 is provided in the middle section of the first driving shaft 32, and the dry material dispersing portion 323 is in a cone shape.
[0042] When the above device is used, the dry material is dispersed along the generatrix by the cone when passing through the discharge chamber 30 from top to bottom, and is not likely to fall on the middle area of the baffle 31 in a concentrated manner.
[0043] Furthermore, a guide groove 3231 is provided on the conical surface of the dry material dispersing portion 323, and the guide groove 3231 is in a right spiral shape from top to bottom.
[0044] When the above device is used, the dry material dispersing portion 323 rotates clockwise with the first driving shaft 32, and generates a downward vortex through the guide groove 3231 with a right spiral structure, so that the dry material is dispersed to the surroundings under the disturbance of the vortex, further improving the dispersion degree of the dry material and avoiding local accumulation of the dry material.
[0045] In combination with the multiple structures and features in the above-mentioned embodiments, the dry material entering the discharge chamber 30 can be pre-processed so that the dry material falls onto the baffle 31 in a relatively discrete state, so that it can quickly pass through the discharge hole 311 or be scraped off from the edge of the baffle 31 by the material removal rod 321, thereby ensuring the efficiency of the dry material entering the double-layer kneading pot 20 and preventing the dry material from accumulating above the baffle 31.
[0046] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
