Description

Technical Field

[0001] The invention relates to the technical field of insulated cable porcelain column mixing equipment, in particular to a mixing equipment for processing mineral insulated cable porcelain columns. Background Art

[0002] As a fireproof cable, mineral insulated cable plays a very important role in the national economic construction. Its excellent fire resistance and electrical properties make it the first choice cable in many fields, such as high-rise buildings, subways, airports, nuclear power plants, etc. As an important part of the cable, the quality and performance of the mineral insulated cable porcelain column directly affect the overall performance and service life of the cable. In the processing of mineral insulated cable porcelain column, the mixing equipment plays a vital role.

[0003] Most of the current mixing equipment has the following disadvantages when in use. First, the main function of the mixing equipment is to fully mix raw materials such as magnesium oxide powder and binder. Magnesium oxide powder may generate static electricity due to friction, contact or separation before mixing. The accumulation of static electricity will lead to an increase in the attraction between powder particles, thereby forming powder agglomerates. Powder agglomerates will affect the uniformity of mixing, causing the magnesium oxide powder concentration in some areas to be too high or too low. Static electricity may also cause safety hazards such as dust explosions, posing a threat to the production environment and personnel safety. Second, the stirring shaft strength of most of the current mixing equipment is limited, and the stirring shaft jumps greatly at high speed, especially the shaking amplitude of the stirring bottom is large, and it may even hit the inner wall of the reactor. The shaking of the stirring shaft will affect the uniformity and efficiency of mixing, making it impossible for materials in some areas to be fully mixed. Long-term collisions and shaking will also accelerate the wear of the stirring shaft and shorten its service life.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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] Embodiment 1, refer to Figure 1-Figure 6A mixing device for processing mineral insulated cable porcelain columns, comprising a mixing tank 1, a mounting frame 42 is installed on the top of the mixing tank 1, a motor 4 is installed on the top of the mounting frame 42, a transmission shaft 41 is fixedly connected to the output end of the motor 4, the transmission shaft 41 passes through the top wall of the mixing tank 1 and its end extends to the inside of the mixing tank 1, a material guide table 2 is fixedly arranged on the inner bottom of the mixing tank 1, and a feeding port 11 for feeding magnesium oxide powder is opened on the top of the mixing tank 1. First, the dried magnesium oxide powder is fed into the mixing tank 1 through the feeding port 11. In the present application, magnesium oxide is selected as the insulating material for the insulated cable magnetic column, and magnesium oxide and aluminum oxide are used as the insulating material. , silicon oxide is a common inorganic insulating material. It is found through test comparison that the insulation resistance of magnesium oxide at 500°C is 1 and 1.5 orders of magnitude higher than that of aluminum oxide and silicon oxide, respectively. Therefore, high-purity magnesium oxide is selected as the insulation. In addition, magnesium oxide also has sufficient resistance to neutron and gamma-ray radiation, which makes the application field of cable armored wire wider. A discharge pipe 12 is fixedly arranged at the bottom of the mixing tank 1 for discharging the material after the mixing is completed. An adhesive injection pipe 13 for filling the adhesive is arranged on the side wall of the mixing tank 1. The adhesive is put into the mixing tank 1 through the adhesive injection pipe 13, and the material is made into a paste after mixing with the powder. It also includes:

[0036] Mixing component: The mixing component is arranged inside the mixing tank 1, and is used to mix the raw materials for processing the cable porcelain column;

[0037] Rolling anti-static component: The rolling anti-static component is arranged above the mixing component. The rolling anti-static component is used to crush and remove static electricity from the raw materials for cable porcelain column processing.

[0038] Furthermore, a discharge port 21 is provided in the middle of the guide platform 2 as a guide port for the mixed materials. The top end of the discharge pipe 12 is connected to the bottom end of the discharge port 21. A solenoid valve 121 for controlling the discharge is installed on the discharge pipe 12 near the discharge port 21. After the magnesium oxide powder and the adhesive are mixed, the solenoid valve 121 is opened to send the paste powder to the press through the discharge pipe 12 for pressing and forming into a porcelain column. The adhesive can be cellulose, paraffin, etc. Cellulose has good adhesion and plasticity, and can effectively adhere raw materials such as magnesium oxide powder. During the pressing process, cellulose can maintain the shape of the paste to ensure the molding accuracy of the porcelain column tube blank. Cellulose has a certain lubricity and can form a thin lubricating film between the mold and the porcelain column tube blank, so that the pressed porcelain column tube blank can be easily removed from the mold, reducing the friction and resistance during demolding. The selection of adhesives such as cellulose and paraffin not only meets the molding and demolding requirements during the processing of mineral insulated cable porcelain columns, but also has the advantages of low cost, easy acquisition and environmental protection.

[0039] The mixing assembly includes a mounting sleeve 5 fixedly mounted on a transmission shaft 41 inside the mixing tank 1, a plurality of groups of diagonal struts 51 are symmetrically mounted on the upper and lower sides of the mounting sleeve 5, a connecting ring 52 is mounted on the end of the diagonal struts 51, a plurality of vertical struts 53 are fixedly connected between the diagonal struts 51 located on the upper and lower sides of the mounting sleeve 5, a connecting rod 54 is fixedly connected to one side of the connecting ring 52 facing the side wall of the mixing tank 1, a scraper 55 is fixedly connected to the end of the connecting rod 54, a plurality of groups of diagonal struts 51 are distributed in a ring shape along the central axis of the transmission shaft 41, and there are gaps between adjacent vertical struts 53. By setting the above-mentioned mixing assembly, a lantern-shaped stirring paddle can be formed, and scrapers 55 for cleaning the inner wall of the mixing tank 1 are additionally arranged on both sides thereof.

[0040] It should be noted that a conical hollow is provided in the middle of the material guide platform 2 to facilitate material discharge. The scraper 55 is L-shaped, and the end faces of the scraper 55 are respectively against the inner wall of the mixing tank 1 and the upper side wall of the material guide platform 2. When the transmission shaft 41 rotates, the scraper 55 can scrape off the powder that may adhere to the inner wall of the mixing tank 1 and the upper side wall of the material guide platform 2, so that this part of the material can also be mixed, thereby improving the overall mixing effect and material utilization rate. The lower end of the scraper 55 is located on the outside of the discharge port 21, ensuring that the scraper 55 can effectively cover the powder on the material guide platform 2, and there is a gap between the lower end of the transmission shaft 41 and the top of the discharge port 21, ensuring that the powder can enter the discharge port 21 through the gap between the transmission shaft 41 and the scraper 55, and then be discharged through the discharge pipe 12.

[0041] In this embodiment, the dried magnesium oxide powder is fed into the mixing tank 1 through the feed port 11. Magnesium oxide is selected as an insulating material because its insulation resistance at 500° C. is 1 and 1.5 orders of magnitude higher than that of aluminum oxide and silicon oxide, respectively, and it has sufficient resistance to neutron and gamma ray radiation. An adhesive (such as cellulose, paraffin, etc.) is fed into the mixing tank 1 through the adhesive injection pipe 13.

[0042] The motor 4 is started, driving the transmission shaft 41 and the mounting sleeve 5 fixed thereon to rotate. The mounting sleeve 5 forms a unique lantern-shaped stirring paddle through the diagonal support rod 51, the connecting ring 52, the vertical support rod 53 and the connecting rod 54. This design not only increases the strength and stability of the stirring paddle, but also enables a more complex and uniform flow pattern to be produced during the stirring process, so that the raw materials can be more fully mixed, thereby improving the stirring efficiency. As the mounting sleeve 5 rotates, the lantern-shaped stirring paddle also begins to make a circular motion in the mixing tank 1. This motion not only fully mixes the raw materials such as magnesium oxide powder in the mixing tank 1, but also achieves a more detailed stirring and dispersion of the raw materials through the special shape of the stirring paddle and the cooperation of the scraper 55.

[0043] It should be noted that since the lantern-shaped stirring paddle has multiple branch structures, these structures can increase the contact area with the raw materials, thereby further improving the stirring efficiency. The branch structure of the lantern-shaped stirring paddle can penetrate into every corner of the raw materials to achieve more detailed stirring and ensure the uniformity and consistency of the raw materials. Compared with ordinary stirring paddles, the lantern-shaped stirring paddle can more effectively reduce the stirring dead corners in the mixing tank 1, so that the raw materials can be fully mixed in each area.

[0044] While the stirring paddle is moving, the scraper 55 connected to the end of the connecting rod 54 also starts to stir and scrape in the mixing tank 1. The design of the scraper 55 enables it to fit tightly against the inner wall of the mixing tank 1 and the upper side wall of the material guide table 2, thereby ensuring that during the stirring process, the powder adhering to these walls can also be effectively scraped off and participate in the mixing process. This not only improves the mixing effect, but also ensures that there is no powder residue on the inner wall of the mixing tank 1 and the material guide table 2, thereby improving the material utilization rate and the uniformity of the product; after the mixing is completed, the solenoid valve 121 is opened, and the paste powder is discharged through the discharge port 21 and the discharge pipe 12, and sent to the press to be pressed into a porcelain column shape.

[0045] In summary, by setting up the lantern-shaped stirring paddle and scraper 55, the stirring dead corners in the mixing tank 1 can be more effectively reduced, making the mixing more uniform and improving the mixing effect. The scraper 55 scrapes the inner wall of the mixing tank 1 and the upper side wall of the material guide platform 2 to ensure that there is no powder residue, improve the material utilization rate, and further improve the mixing effect.

[0046] Example 2, refer to Figure 4-Figure 10 The rolling static removal component includes a conical filter cartridge 3, a turntable 6, a rolling roller 7, a support sleeve 8 and a conductive sleeve 9. The support sleeve 8 is fixedly connected to the side wall of the mixing tank 1, and a conductive ring 91 is fixedly connected to the bottom of the turntable 6. A wire 81 is arranged inside the support sleeve 8. The conical filter cartridge 3 is fixedly connected to the inner wall of the mixing tank 1. The magnesium oxide powder put in can be further screened through the conical filter cartridge 3. The turntable 6 is fixedly connected to the transmission shaft 41 and is rotatably engaged with the bottom of the conical filter cartridge 3. Several limit platforms 61 are arranged in an annular manner on the side wall of the turntable 6. A limit groove 76 matching the limit platform 61 is arranged at the bottom of the rolling roller 7. When the transmission shaft 41 rotates, the turntable 6 will start to rotate around the conical filter cartridge 3. The adhesive injection pipe 13 is located at the lower side of the conical filter cartridge 3 to ensure that the adhesive will not interfere with the unscreened magnesium oxide powder.

[0047] Furthermore, the rolling roller 7 is rotatably engaged with the limit platform 61 through the limit groove 76, and the outer wall of the rolling roller 7 is against the side wall of the conical filter cartridge 3. When the turntable 6 rotates, the rolling roller 7 will also roll along the surface of the conical filter cartridge 3, so that the magnesium oxide powder on the conical filter cartridge 3 can be rolled. On the one hand, it can effectively crush the agglomerated powder clumps, and on the other hand, it can effectively absorb the static electricity in the magnesium oxide powder. The interior of the rolling roller 7 is provided with a mounting groove 75 and a mounting cavity 74, and an electrostatic adsorption rod 72 is installed in the mounting groove 75, and a conductive block 73 is installed in the mounting cavity 74. The bottom of the mounting groove 75 is connected to the top of the mounting cavity 74, and the lower part of the conductive block 73 passes through the side wall of the mounting cavity 74. A plurality of contact grooves 71 are equidistantly arranged in a ring shape on the outer side of the rolling roller 7, and the inner end of the contact groove 71 passes through the side wall of the mounting groove 75.

[0048] The lower end of the mounting groove 75 contacts the top of the conductive block 73, and the partial side wall of the electrostatic adsorption rod 72 is located in the contact groove 71 and is sealed and connected to the contact groove 71, ensuring that the magnesium oxide powder can effectively contact the electrostatic adsorption rod 72, thereby removing the static electricity on the magnesium oxide powder. The conductive block 73 is rotatably connected to the rolling roller 7, and a through groove 62 is provided on the turntable 6 for the lower part of the conductive block 73 to pass through. The ends of the through groove 62 respectively penetrate the side walls of the limit table 61 and the turntable 6, and the bottom of the conductive block 73 passes through the through groove 62 and contacts the conductive ring 91.

[0049] The conductive sleeve 9 is rotatably fitted with the bottom of the turntable 6 to prevent powder from entering. The end of the support sleeve 8 located inside the mixing tank 1 is fixedly connected to the conductive sleeve 9, and the conductive sleeve 9 can be effectively supported by the support sleeve 8. The conductive sleeve 9 is provided with a groove matching the conductive ring 91 inside the conductive sleeve 9. The conductive sleeve 9 is rotatably connected to the conductive ring 91 through the groove. A conductive area is provided inside the groove, one side of the conductive area is in contact with the conductive ring 91, and the other side is fixedly connected to the end of the wire 81. The static electricity is transferred from the electrostatic adsorption rod 72 to the conductive block 73, and then transmitted to the conductive area through the conductive ring 91, and finally the static electricity is discharged through the wire 81.

[0050] It should be noted that the conical filter cartridge 3, turntable 6, and rolling roller 7 are all made of insulating materials. During the electrostatic treatment process, the insulating material can prevent current leakage, ensuring that static electricity can be effectively discharged without causing damage to the equipment. The electrostatic adsorption rod 72 is made of carbon fiber, which is a material with high conductivity. It can quickly adsorb static electricity from magnesium oxide powder and transfer it to the electrostatic adsorption rod 72. This high conductivity ensures that static electricity can be effectively discharged, thereby avoiding safety hazards such as dust explosions caused by static electricity accumulation. The outside of the electrostatic adsorption rod 72 is wrapped with fine copper wire, and the static electricity in the magnesium oxide powder can be effectively transferred to the electrostatic adsorption rod 72 through the fine copper wire. The electrostatic adsorption rod 72, the conductive block 73, the conductive ring 91, the conductive area and the wire 81 are electrically connected to ensure that static electricity can be effectively discharged.

[0051] In this embodiment, after the magnesium oxide powder is put into the mixing tank 1, it is first screened through the conical filter cartridge 3 to remove larger particles or impurities, and the motor 4 is started, and the transmission shaft 41 starts to drive the turntable 6 to rotate. Since the turntable 6 is rotatably engaged with the bottom of the conical filter cartridge 3, the rotation of the turntable 6 will drive the rolling roller 7 arranged thereon to roll along the surface of the conical filter cartridge 3.

[0052] Static electricity removal: During the rolling process, the rolling roller 7, through the physical rolling action, on the one hand, crushes the agglomerated powder balls so that the powder that meets the standards falls down. On the other hand, the magnesium oxide powder on the conical filter cartridge 3 will contact the electrostatic adsorption rod 72 through the contact groove 71. The electrostatic adsorption rod 72 will absorb the static electricity in the powder through the fine copper wire on its surface. The electrostatic adsorption rod 72 is made of carbon fiber and has high conductivity. The fine copper wire wrapped on the outside enhances the contact area with the magnesium oxide powder, thereby more effectively transmitting static electricity. The static electricity is transferred from the electrostatic adsorption rod 72 to the conductive block 73, and then to the conductive ring 91 on the turntable 6. Because the conductive ring 91 is in contact with the conductive area inside the conductive sleeve 9, the conductive area then conducts the static electricity to the safe grounding point outside the mixing tank 1 through the wire 81.

[0053] The rolling roller 7 crushes the agglomerated powder through physical rolling action, and cooperates with the conical filter cartridge 3 to remove larger particles or impurities in the magnesium oxide powder, ensuring that the quality of the powder entering the next step of mixing meets the standards, making the powder more delicate and uniform, which helps to improve the quality of the final product. At the same time, through the combination of the rolling roller 7 and the electrostatic adsorption rod 72, the static electricity in the magnesium oxide powder can be efficiently removed to prevent safety hazards such as dust agglomeration and explosion caused by static electricity accumulation.

[0054] Embodiment 3, in this embodiment, refer to Figure 2-Figure 7 In combination with Example 1 and Example 2, it can be known that in the present application, the transmission shaft 41 is supported in multiple layers. First, a layer of support is provided between the mounting frame 42 and the top of the mixing tank 1, which is the top support. Then, the middle part of the transmission shaft 41 is supported by the cooperation among the turntable 6, the conical filter cartridge 3, the conductive sleeve 9 and the support sleeve 8. Finally, by setting the lantern-shaped stirring paddle and the scraper 55, the lantern-shaped stirring paddle can more effectively stir the material in the mixing tank 1 and improve the mixing effect. At the same time, the scraper 55 is always against the inner wall of the mixing tank 1 and the material guide platform 2, which not only plays the role of cleaning the tank wall and the material guide platform 2, but also provides bottom support for the transmission shaft 41.

[0055] The above-mentioned multi-layer support structure can effectively reduce the bouncing and shaking of the transmission shaft 41 during high-speed rotation, especially at the mixing bottom, and can significantly reduce the shaking amplitude, avoid collision with the inner wall of the mixing tank 1, and improve the overall stability and safety of the equipment. At the same time, it also reduces the friction and wear of the transmission shaft 41 during rotation, and extends the service life of the equipment.
