Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly flame retardant production, in particular to mixing equipment used for the production of environmentally friendly flame retardants. Background Art

[0002] Flame retardants are functional additives that make flammable polymers flame retardant. They are mainly designed for the flame retardancy of polymer materials. There are many types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the method of use. Additive flame retardants are added to polymers by mechanical mixing to make the polymers flame retardant. Additive flame retardants mainly include organic flame retardants and inorganic flame retardants, halogen flame retardants (organic chlorides and organic bromides) and non-halogen. Organic flame retardants are represented by bromine, phosphorus-nitrogen, nitrogen, red phosphorus and compounds. Inorganic flame retardants are mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flame retardant systems. Reactive flame retardants participate in the polymerization reaction as a monomer, so that the polymer itself contains flame retardant ingredients. Its advantage is that it has little effect on the performance of polymer materials and has long-lasting flame retardancy.

The above scheme improves the uniformity of mixing, shortens the mixing time, and improves the use efficiency of the mixing equipment through the setting of the corresponding mechanism on the mixing equipment.

Moreover, it cannot heat the temperature inside the mixing barrel when in use, which reduces the practicality of the equipment. Moreover, it cannot scrape the flame retardant raw materials adhering to the inner wall of the mixing barrel when in use, which reduces the practicality of the equipment. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0020] See also Figure 1 - Figure 3The utility model provides a technical solution: a mixing device for the production of environmentally friendly flame retardants, comprising a mixing barrel 1, a storage barrel 2, a motor 6 and a sealing assembly 14. The top of the mixing barrel 1 is fixedly connected to two storage barrels 2, and the insides of the two storage barrels 2 are fixedly connected to a feeding pipe 3. The bottom ends of the two feeding pipes 3 extend to the inside of the mixing barrel 1. The insides of the two feeding pipes 3 are provided with valves 4. The tops of the two storage barrels 2 are rotatably connected to a rotating plate 5, so that the device can be passed through when discharging a variety of raw materials. Materials are added to the interior of the mixing barrel 1 through two feeding pipes 3 at the same time, which improves the mixing effect of the equipment. A motor 6 is fixedly connected to the top of the mixing barrel 1. The model of the motor 6 is Y80M1-2. The output end of the motor 6 extends to the interior of the mixing barrel 1 and is fixedly connected to a rotating shaft 7. The outside of the rotating shaft 7 is fixedly connected to a frame 8. A lower barrel 13 is fixedly connected to the interior of the mixing barrel 1 and located below the rotating shaft 7. A sealing assembly 14 is arranged inside the lower barrel 13. The bottom end of the lower barrel 13 extends to the outside of the mixing barrel 1.

[0021] Furthermore, a plurality of stirring blades 9 are fixedly connected to the interior of the frame 8, and a plurality of mixing blades 10 are fixedly connected to the exterior of the rotating shaft 7 and located inside the frame 8, which can speed up the mixing speed and improve the practicability of the equipment.

[0022] Furthermore, two connecting rods 11 are fixedly connected to the outside of the frame 8, and a scraper 12 is fixedly connected to one end of the two connecting rods 11 away from the frame 8. The side of the scraper 12 away from the connecting rods 11 is in contact with the inner wall of the mixing barrel 1, so that the raw materials adhering to the inner wall of the mixing barrel 1 can be scraped off, which is convenient for the staff to clean later.

[0023] Furthermore, the sealing assembly 14 includes a mounting groove 141, which is opened inside the lower barrel 13, and a first electromagnetic coil 142 is fixedly connected inside the mounting groove 141, and a spring 143 is fixedly connected inside the mounting groove 141, and a push plate 144 is fixedly connected to one end of the spring 143 away from the first electromagnetic coil 142, and the push plate 144 slides inside the mounting groove 141, and a sealing plate 146 is fixedly connected to one end of the push plate 144 away from the spring 143, and a side of the sealing plate 146 away from the push plate 144 contacts the inner wall of the lower barrel 13, and a side of the push plate 144 close to the first electromagnetic coil 142 is fixedly connected to a second electromagnetic coil 145, and the first electromagnetic coil 142 and the second electromagnetic coil 145 are fixedly connected. 45 magnetic poles are the same, by powering the first electromagnetic coil 142 and the second electromagnetic coil 145, a repulsive force is generated between the first electromagnetic coil 142 and the second electromagnetic coil 145, and the repulsive force is greater than the pulling force of the spring 143. The repulsive force pushes the push plate 144 to move, and when the push plate 144 moves, it drives the sealing plate 146 to continue to twist and move. At this time, the discharge barrel 13 can be sealed. When it is necessary to discharge, stop powering the first electromagnetic coil 142 and the second electromagnetic coil 145. At this time, the repulsive force disappears, and the spring 143 drives the push plate 144 to reset. At this time, the sealing plate 146 is retracted into the interior of the mounting groove 141, and the discharge operation can be carried out without the need for manual opening by the staff, thereby improving the safety of the equipment.

[0024] Furthermore, a mounting cavity 15 is provided inside the mixing barrel 1, and a heating plate 16 is fixedly connected inside the mounting cavity 15, which can heat the temperature inside the mixing barrel 1, enhance the mixing effect, and improve the practicability of the equipment.

[0025] In summary: by placing the raw materials to be added inside the storage barrel 2, by opening the valve 4, when the valve 4 is opened, the raw materials inside the storage barrel 2 are transported to the mixing barrel 1 through the feeding pipe 3, so that the staff can conveniently perform the feeding operation, by starting the motor 6, when the motor 6 is started, the rotating shaft 7 is driven to rotate, when the rotating shaft 7 rotates, the frame 8 is driven to rotate, and when the frame 8 rotates, the stirring blade 9 is driven to rotate. At the same time, when the rotating shaft 7 rotates, the mixing blade 10 is driven to rotate. At this time, the various raw materials inside the mixing barrel 1 can be mixed, and the mixing efficiency is improved. At the same time, when the frame 8 rotates, the connecting rod 11 is driven to rotate, and when the connecting rod 11 rotates, the scraper 12 is driven to rotate. The scraper 12 can scrape the raw materials adhering to the inner wall of the mixing barrel 1 when it rotates, which is convenient for the staff. The staff will carry out subsequent cleaning by starting the heating plate 16. When the heating plate 16 is started, the temperature inside the mixing barrel 1 can be heated to enhance the mixing effect and improve the practicability of the equipment. By supplying power to the first electromagnetic coil 142 and the second electromagnetic coil 145, a repulsive force is generated between the first electromagnetic coil 142 and the second electromagnetic coil 145, and the repulsive force is greater than the pulling force of the spring 143. The repulsive force pushes the push plate 144 to move, and when the push plate 144 moves, it drives the sealing plate 146 to continue to twist and move, and the unloading barrel 13 can be sealed at this time. When unloading is required, the power supply to the first electromagnetic coil 142 and the second electromagnetic coil 145 is stopped, and the repulsive force disappears at this time, and the spring 143 drives the push plate 144 to reset. At this time, the sealing plate 146 is retracted into the interior of the mounting groove 141, and the unloading operation can be carried out at this time.
