Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a carbon heating device. Background Technique

[0002] In the process of carbon production, kneading is an important process in forming production. Its purpose is to make the dry material and asphalt mix evenly with a uniform structure. The asphalt evenly covers the surface of the dry material particles and partially penetrates into the pores of the particles. The cohesive force of the asphalt combines all the particles with each other, so that the paste has good plasticity. The temperature of the dry material has a great influence on the quality of the paste. With the increase of the dry material temperature, the wetting contact angle between the asphalt and the dry material decreases, and the capillary permeability increases, that is, the wetting effect of the asphalt on the dry material is good, and the plasticity of the paste is also good, which is convenient for the forming of green blocks and the dense and uniform structure. On the contrary, when the dry material temperature is relatively low, the wettability of the asphalt to the dry material becomes poor, which is easy to cause uneven kneading, the plasticity of the paste is not good, the paste is not easy to be pressed, and the green block is not dense and the volume density is low.

[0003] Chinese Utility Model CN212198512U, a paste hopper for carbon production, designs a carbon heating and mixing structure. Its principle is to set water pipes on the outer cylinder to heat the internal materials through water circulation, and at the same time start the motor to drive the spiral blades to rotate, so that the internal materials are mixed and heated more evenly.

[0004] However, in the existing device during use, the spiral blades are arranged inside the outer cylinder and no pipes are arranged on the outside. When rotating, the materials will fall off the spiral blades. The effect of lifting the materials upward during rotation is poor and the mixing speed is slow. Therefore, in view of the above-mentioned problems, a heating and stirring structure with better mixing effect is designed. Content of the Utility Model

[0031] In the carbon production process, kneading is an important process in molding production. Its purpose is to evenly mix dry materials and asphalt, with a uniform structure, so that the asphalt evenly covers the surface of dry material particles and partially penetrates into the pores of the particles. The cohesive force of the asphalt binds all the particles together, making the paste have good plasticity. The temperature of the dry materials has a great influence on the quality of the paste. With the increase in the temperature of the dry materials, the wetting contact angle between the asphalt and the dry materials decreases, and the capillary permeability increases, that is, the wetting effect of the asphalt on the dry materials is good, and the plasticity of the paste also becomes better, facilitating the molding of green blocks and a dense and uniform structure. On the contrary, when the temperature of the dry materials is relatively low, the wettability of the asphalt to the dry materials becomes poor, easily causing uneven kneading, and the plasticity of the paste is also not good, making it difficult to press the paste and the green blocks are not dense with a low bulk density.

[0032] In the related art, a water pipe is provided on the outer cylinder to heat the internal materials through water circulation. At the same time, the motor is started to drive the spiral blade to rotate, so that the internal materials are mixed and heated more evenly. However, in the existing device during use, the spiral blade is arranged inside the outer cylinder and there is no pipeline arranged outside. When rotating, the materials will fall off the spiral blade. The effect of lifting the materials upward during rotation is poor and the mixing speed is slow.

[0033] To solve the problems in the related art to a certain extent, the embodiment of this application provides a carbon heating device. During use, the materials are added into the interior of the outer cylinder body 11 through the feed pipe 12, and then through the heating pipe embedded in the outer cylinder body 11, the temperature inside the outer cylinder body 11 is kept stable. Then, the motor 21 is connected to an external power supply to drive the rotating rod 22 to rotate. At this time, the spiral blade 23 rotates accordingly to lift the materials into the interior of the inner cylinder 24 and move upward. Finally, the materials are discharged from the top of the inner cylinder 24, which can make the materials inside the outer cylinder body 11 continuously move and contact the inner side wall of the outer cylinder body 11, thereby continuously heating the materials. After kneading is completed, the motor 21 can be started to drive the rotating rod 22 to rotate in the reverse direction, so that the spiral blade 23 also rotates in the reverse direction, and the internal materials can be discharged from the bottom discharge port. While the rotating rod 22 is rotating, the cross bar 31 drives the scraper 32 to rotate on the inner side wall of the outer cylinder body 11, and the materials adhered to the inner side wall can be scraped off and flow downward along the scraper 32.

[0034] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0035] In conjunction with Figures 1-4 , an embodiment of the present application provides a carbon heating device, including: an outer cylinder 11 with a feed pipe 12 provided at its top, and a plurality of heating pipes are embedded in the outer cylinder 11, and the internal temperature is maintained through the heating pipes; a material lifting assembly 2 is provided inside the outer cylinder 11, and the material lifting assembly 2 includes: a motor 21 provided at the top of the outer cylinder 11, and the output shaft thereof is inserted into the inside of the outer cylinder 11; a rotating rod 22 is provided inside the outer cylinder 11, and the top end thereof is connected to the bottom output shaft of the motor 21 through a coupling; a spiral blade 23 is fixedly provided on the outer side of the rotating rod 22; an inner cylinder 24 is sleeved on the outer side of the spiral blade 23; a connecting rod 25 is provided on the outer side wall of the bottom end of the inner cylinder 24, and the other end of the connecting rod 25 is connected to the inner side wall of the outer cylinder 11.

[0036] Specifically, the outer cylinder 11 is mainly composed of an external jacket hopper and an internal heat-conducting oil pipe group. After heat balance calculation, the dimensions of the external cylinder and the number of internal pipe groups that meet the requirements are designed. The external cylinder is welded with Q235Bδ12 plates, and the heating pipe group uses 16Mnφ89*10 seamless pipes. The materials are simple and relatively easy to manufacture. By adjusting the external valves, the heat-conducting oil flow rate and pressure of the external jacket and the internal pipe group are adjusted to control the temperature in the hopper, and the anode dry material is heated by controlling the residence time of the dry material in the hopper.

[0037] During use, the material is added into the inside of the outer cylinder 11 from the feed pipe 12, and then through the heating pipes embedded in the outer cylinder 11, the internal temperature of the outer cylinder 11 is kept stable. Then, the motor 21 is connected to an external power supply to drive the rotating rod 22 to rotate. At this time, the spiral blade 23 rotates to lift the material into the inside of the inner cylinder 24 and move upward. Finally, the material is discharged from the top of the inner cylinder 24, so that the material inside the outer cylinder 11 can move continuously and contact the inner side wall of the outer cylinder 11, thereby continuously heating the material. After the kneading is completed, the motor 21 can be started to drive the rotating rod 22 to rotate in the reverse direction, so that the spiral blade 23 also rotates in the reverse direction, and the material inside can be discharged from the bottom discharge port.

[0038] In some embodiments, the bottom of the outer cylinder 11 is designed in a funnel shape.

[0039] When in use, the design of the bottom of the outer cylinder 11 in a funnel shape can make it easier to accumulate materials at the bottom, and it is convenient to lift the materials into the inside of the inner cylinder 24 when the spiral blade 23 rotates.

[0040] In some embodiments, the material lifting assembly 2 further includes: a plurality of fan blades 26 are provided on the outer sidewall of the rotating rod 22.

[0041] During use, when the material flows out from the top of the inner cylinder 24, the fan blades 26 rotate following the rotating rod 22, and the material can be evenly scattered inside the outer cylinder body 11.

[0042] In some embodiments, the material lifting assembly 2 further includes: a baffle 27 is fixedly sleeved on the outer sidewall of the rotating rod 22.

[0043] During use, the setting of the baffle 27 can limit the upward ejection of the material, so that the material can better contact the fan blades 26 after flowing out from the top of the inner cylinder 24.

[0044] In some embodiments, the top surface of the baffle 27 is inclined.

[0045] During use, the inclined top surface of the baffle 27 can prevent the material from accumulating easily at the top of the baffle 27 during feeding.

[0046] In some embodiments, a rotating assembly 3 is provided inside the outer cylinder body 11. The rotating assembly 3 includes: a first cross bar 31 is provided on the outer sidewall of the rotating rod 22; a scraper 32 is provided on the inner sidewall of the outer cylinder body 11, and one side thereof is fixedly connected to one end of the first cross bar 31.

[0047] During use, while the rotating rod 22 rotates, the scraper 32 is driven to rotate on the inner sidewall of the outer cylinder body 11 through the first cross bar 31, and the material adhered to the inner sidewall can be scraped off and flow downward along the scraper 32.

[0048] In some embodiments, two of the first cross bar 31 and the scraper 32 are symmetrically arranged, and the cross section of the scraper 32 is triangular.

[0049] During use, the two symmetrically arranged scrapers 32 and the first cross bar 31 can improve the scraping efficiency of the inner sidewall of the outer cylinder body 11. At the same time, the triangular cross section of the scraper 32 can form an included angle between the scraper 32 and the inner sidewall of the outer cylinder body 11 when the scraper 32 rotates, making it easier for the material to gather together and flow downward along the included angle.

[0050] In some embodiments, the rotating assembly 3 further includes: a ring body 33 is rotatably sleeved on the outer sidewall of the inner cylinder 24; a second cross bar 34 is provided on the outer sidewall of the ring body 33, and the other end thereof is connected to the scraper 32.

[0051] During use, the settings of the ring body 33 and the second cross bar 34 can stabilize the position of the scraper 32.

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.
