DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0029] Example 1

[0030] See also Figure 1-6 The present embodiment provides an insulation pouring device for producing autoclaved aerated concrete blocks, including a mixing box 3 and a stirring rod 9 for mixing concrete raw materials. The stirring rod 9 is installed in the inner cavity of the mixing box 3 and is rotated by a driving motor. The concrete raw materials are filled into the inner cavity of the mixing box 3, and the driving motor is started to rotate the stirring rod 9, which is beneficial to the rapid mixing and production of the concrete raw materials inside the mixing box 3.

[0031] A heating device 4 for heating concrete raw materials is installed on the outside of the mixing box 3. An insulation component for keeping itself warm is arranged on the outside of the mixing box 3. Starting the heating device 4 can quickly heat the concrete raw materials inside the mixing box 3 to prevent the concrete raw materials from solidifying due to low temperature, which is beneficial to the continuous production of concrete raw materials.

[0032] The insulation component includes an electric heating wire 18 and an insulation tube 2. The insulation tube 2 is fixedly sleeved in the inner cavity of the mixing box 3, and the inner cavity of the insulation tube 2 is connected with the inner cavity of the mixing box 3. The inner cavity of the insulation tube 2 is connected with the outer wall of the mixing box 3. At the same time, under the action of the mixing box 3, the inner cavity of the insulation tube 2 is sealed.

[0033] A sealing ring 17 is fixedly installed at the bottom of the inner cavity of the insulation tube 2, and the electric heating wire 18 is fixedly installed in the inner cavity of the sealing ring 17. A water retaining ring 11 is fixedly installed in the inner cavity of the insulation tube 2, and water is filled between the water retaining ring 11 and the sealing ring 17. The sealing ring 17 protects the electric heating wire 18 and prevents the electric heating wire 18 from directly contacting water, which is beneficial to the protection of the electric heating wire 18. At the same time, after the electric heating wire 18 is energized, heat exchange occurs between the electric heating wire 18 and the water inside the insulation tube 2, thereby heating the water inside the insulation tube 2.

[0034] Furthermore, the heat generated by the electric heating wire 18 is transferred to the sealing ring 17 , and heat is exchanged between the sealing ring 17 and the water inside the heat preservation tube 2 . The sealing ring 17 is made of metallic copper, which is beneficial to improving the thermal conductivity and service life of the sealing ring 17 .

[0035] The water retaining ring 11 is located directly above the sealing ring 17, and a plurality of transmission pipes 10 are fixedly installed on the top of the water retaining ring 11 in a circular distribution. The transmission pipe 10 is fixedly installed with a plurality of nozzles connected to its own inner cavity near the outer wall of the mixing box 3, wherein the transmission pipe 10 is horizontally installed on the top of the water retaining ring 11, and the outer wall of the transmission pipe 10 is bent, which is beneficial to increase the use area of ​​the transmission pipe 10 inside the insulation tube 2.

[0036] A connecting pipe is fixedly installed on the outer wall of the transmission pipe 10, and a plurality of mounting holes are arranged in a ring shape on the top of the water retaining ring 11. One end of the connecting pipe passes through the mounting hole and extends to the bottom of the water retaining ring 11. When the water inside the insulation tube 2 is heated to boiling, a large amount of steam is generated. Under the action of the water retaining ring 11, the generated steam is concentrated between the water retaining ring 11 and the bottom of the inner cavity of the insulation tube 2. Under the action of air pressure, the steam quickly flows to the interior of the transmission pipe 10 through a plurality of connecting pipes, and then transmits the water vapor to the top of the water retaining ring 11 through a plurality of nozzles outside the transmission pipe 10, which is beneficial to heating the outer wall of the mixing box 3 and keeping the insulation tube 2 and the outer wall of the mixing box 3 warm, effectively preventing the concrete raw materials inside the mixing box 3 from exchanging heat with the outside air, thereby reducing the evaporation rate of water in the concrete raw materials, making it difficult for the concrete raw materials attached to the inner wall of the mixing box 3 to solidify, and effectively reducing the adverse effects on the subsequent processing of the concrete raw materials.

[0037] The insulation component also includes a generator 6 for supplying power to the electric heating wire 18. The generator 6 is fixedly mounted on the outer wall of the mixing box 3. The power input end of the generator 6 and the outer wall of the stirring rod 9 are fixedly sleeved with a tensioning wheel 5. The two tensioning wheels 5 are rotatably connected by a tensioning belt. When the stirring rod 9 rotates, the power input end of the generator 6 rotates accordingly through the cooperation between the two tensioning wheels 5 and the tensioning belt, which is conducive to the generator 6 generating current, thereby energizing the electric heating wire 18.

[0038] The outer wall of the heat preservation cylinder 2 is fixedly mounted with a mounting shell 7 , and a plurality of storage batteries 16 are mounted in the inner cavity of the mounting shell 7 . The mounting shell 7 can carry the plurality of storage batteries 16 , which is beneficial to the use of the plurality of storage batteries 16 .

[0039] The positive and negative poles of the battery 16 are connected to the positive and negative pole terminals of the generator 6 through wires, and the battery 16 provides electrical energy to the electric heating wire 18 through the wires. Multiple batteries 16 can store the electrical energy generated by the generator 6, and at the same time use part of the stored electrical energy to power the electric heating wire 18, which is beneficial to saving electrical energy. When the generator 6 stops rotating, the electric heating wire 18 can continue to work.

[0040] The outer wall of the insulation cylinder 2 is provided with a connecting hole connected to its own inner cavity, and a water inlet pipe 14 is fixedly installed in the connected inner cavity. Water can be added to the inside of the insulation cylinder 2 through the water inlet pipe 14 to prevent the water inside the insulation cylinder 2 from drying up due to evaporation, which is beneficial to continuously heating the outer wall of the mixing box 3.

[0041] A sealing bolt 13 is movably installed at one end of the water inlet pipe 14 away from the connecting hole, and a threaded groove compatible with the sealing bolt 13 is opened on the inner wall of the water inlet pipe 14. After water is added to the inside of the insulation tube 2 using the water inlet pipe 14, the sealing bolt 13 is installed into the inside of the water inlet pipe 14. With the cooperation of the sealing bolt 13 and the threaded groove, the water inlet end of the water inlet pipe 14 is sealed to prevent boiling hot water and water vapor generated by water heating from overflowing from the water inlet end of the water inlet pipe 14.

[0042] An air intake pipe connected to the bottom of the water retaining ring 11 is fixedly installed on the top of the water retaining ring 11, and a plug hole compatible with the air intake pipe is opened on the outer wall of the insulation tube 2. The end of the air intake pipe away from the water retaining ring 11 passes through the plug hole and extends to the outside of the insulation tube 2. An air pump 8 for increasing the air flow rate inside the insulation tube 2 is arranged on the outside of the insulation tube 2. Starting the air pump 8 allows the outside air to flow quickly into the insulation tube 2, increasing the air pressure in the chamber between the bottom of the inner cavity of the insulation tube 2 and the water retaining ring 11, which is beneficial to increasing the steam flow rate inside the transmission pipe 10, thereby further increasing the heating rate of the outer surface of the mixing box 3.

[0043] A through hole is fixedly installed on the top of the insulation tube 2, and an exhaust pipe 15 is fixedly installed in the inner cavity of the through hole. A sliding column 19 is elastically installed in the inner cavity of the exhaust pipe 15, and a top pressure spring 20 is fixedly sleeved on the outer wall of the sliding column 19. One end of the top pressure spring 20 is fixedly connected to the inner wall of the exhaust pipe 15. The top pressure spring 20 applies a thrust to the sliding column 19 to continuously move toward the inner cavity of the insulation tube 2, which is beneficial to the fit between the bottom of the sealing plate 12 and the top of the exhaust pipe 15, preventing the exchange of air inside the insulation tube 2 and the outside air, and is beneficial to improving the insulation performance of the insulation tube 2 on the outer surface of the mixing box 3.

[0044] The top of the sliding column 19 extends to the top of the exhaust pipe 15, and a sealing plate 12 for sealing the top of the exhaust pipe 15 is fixedly installed on the top of the sliding column 19. After the internal air pressure of the insulation tube 2 rises to a certain level, the internal gas of the insulation tube 2 applies a thrust to the bottom of the sealing plate 12, so that the bottom of the sealing plate 12 and the top of the exhaust pipe 15 are separated, which is beneficial to the internal pressure relief of the insulation tube 2. When the internal pressure of the insulation tube 2 is relieved to a certain level, the top pressure spring 20 resets the sealing plate 12.

The two transmission gears are rotatably connected by a transmission chain. When the driving motor is started, the transmission gear connected to the power output end of the driving motor rotates. At this time, the transmission gear drives the transmission chain to rotate, so that kinetic energy is transmitted to another transmission gear, which is beneficial to the rotation of the stirring rod 9 and improves the convenience of rotating the stirring rod 9.

[0048] A trolley 1 for easy movement is fixedly installed at the bottom of the mixing box 3, and the bottom of the heating device 4 is fixedly connected to one side of the top of the trolley 1.
