Description

Technical Field

[0001] The invention relates to the technical field of inorganic composite thermal insulation material production equipment, in particular to a production equipment for inorganic composite thermal insulation lightweight material. Background Art

[0002] Inorganic lightweight thermal insulation material is a new type of thermal insulation, energy storage and energy-saving material with the advantages of low thermal conductivity, good frost resistance, light weight, fire resistance, heat insulation, sound insulation and thermal insulation. Inorganic lightweight thermal insulation material mainly includes silicate anti-seepage cement, zeolite powder, basalt micron fiber, alkali-resistant glass fiber staple, condensed silica fume, expanded oil shale particles and hydrophobic expanded rock beads.

[0003] Expanded perlite is made by preheating the raw perlite and heating it to a high temperature, so that the water inside it evaporates quickly and generates pressure, so that the particles expand into a porous structure. These micropores provide good thermal insulation performance and are widely used in the preparation of thermal insulation materials such as walls, roofs, and floors. The volume expansion degree of expanded perlite is usually more than 10 times. At present, the expansion processing of perlite is mainly processed by a perlite expansion device. Referring to the existing document with the publication (announcement) number CN114353507A, a perlite expansion device is disclosed. Fuel is injected into the gas pipe and burned by the burner to provide a heat source, and then air is introduced through the ventilation pipe to assist combustion. The perlite is injected into the transfer box through the feed pipe, and the closing piece is driven by the telescopic cylinder to move and intermittently open the furnace body to allow the perlite to enter the furnace body. After that, the furnace body is immediately closed to prevent heat leakage. The perlite entering the furnace body falls into the spiral mesh groove and rolls downward along the spiral mesh groove for preheating. After the perlite falls out of the spiral mesh groove, it falls on the distribution plate to be further heated. As the telescopic cylinder drives the closing piece to move and inject the perlite raw material, the closing piece drives the tooth plate to move and drives the shifting plate to rotate through the gear to stir and mix the perlite on the distribution plate. The perlite expanded by the heat floats during the turning process and is finally discharged from the discharge pipe.

[0004] In the above device, the expanded perlite is screened out by the buoyancy generated by the airflow. However, since there are many components in the transfer box, the expanded perlite is blocked by many components when it is screened out by the buoyancy generated by the airflow, and it is not convenient to blow it out. At the same time, the perlite is released from the upper layer into the transfer cylinder. The expanded perlite will contact the falling unexpanded perlite during the rising process. The expanded perlite will take away some unexpanded perlite, resulting in a waste of raw materials, or requiring secondary filtration and screening, wasting manpower and material resources.

[0005] Therefore, those skilled in the art are committed to developing a production device for an inorganic composite thermal insulation lightweight material, which is conducive to the rapid expansion and screening of perlite and improves the expansion rate of perlite. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a production device for an inorganic composite thermal insulation lightweight material, which is conducive to the rapid expansion and screening of perlite and improves the expansion rate of perlite.

[0007] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] Production device for inorganic composite thermal insulation lightweight material, including

[0009] A puffing tower, the puffing tower having a puffing chamber;

[0010] A feeding component, the feeding component is located on the upper side of the puffing tower, a feeding end of the feeding component extends to the bottom of the puffing chamber, and a conveying component is installed on the feeding component and close to the upper end of the puffing chamber;

[0011] A rotating component, which is installed at the bottom of the puffing chamber and connected to the end of the feeding component;

[0012] A high-temperature gas component, which is installed at the bottom of the puffing tower, and a gas outlet end of the high-temperature gas component is communicated with the puffing chamber;

[0013] A cooling component, wherein the cooling component has a cooling cavity, and the cooling cavity is communicated with the discharge end of the expanding cavity;

[0014] A stirring device is installed at the discharging end of the cooling component, and at least one automatic feeding component is installed on the stirring device.

[0015] The beneficial effects of the above scheme are as follows: the perlite raw material is piled in the feeding component, and is first transported from the bottom of the feeding component to the rotating component under the action of its own gravity. The rotating component rotates to drive the perlite raw material to rotate and is thrown to the bottom edge of the expanding chamber under the action of centrifugal force. The perlite expands under the continuous action of the high-temperature gas. The expanded perlite increases in volume, decreases in density and continuously accumulates in the expansion chamber. After the expanded perlite accumulates at the upper end of the expanding chamber, it is transported to the cooling chamber under the action of the feeding component for rapid cooling, thereby expanding and forming the perlite raw material.

[0016] When the high-temperature gas component is working continuously, part of the heat is transferred to the rotating component. The perlite raw material is first added to the rotating component to facilitate the pretreatment of the perlite raw material, and then it is thrown to the edge of the puffing chamber under the action of centrifugal force and puffed under the action of high-temperature gas;

[0017] At the same time, since the perlite raw material is added from the bottom of the puffing chamber, the contact between the puffed perlite in the upper layer and the perlite raw material is reduced, thereby reducing the part of the perlite raw material being taken out when the puffed perlite is transported, thereby reducing the consumption of raw materials;

[0018] Moreover, when the rotating parts rotate, they will generate high-frequency and subtle vibrations, which will be transmitted to the side wall of the expansion tower and drive the raw materials and expanded perlite in the expansion chamber to vibrate, thereby vibrating a small amount of perlite raw materials attached to the expanded perlite and dropping it, reducing the impurity content in the expanded perlite and avoiding subsequent secondary filtration and screening;

[0019] Furthermore, the rotation of the rotating component drives the feeding end of the feeding component to rotate, and the perlite raw material is thrown out from the feeding end of the feeding component under the action of centrifugal force, thereby reducing blockage;

[0020] The rotating part rotates and drives the feeding part to rotate to convey the expanded perlite out. The feeding part does not need to add an additional power device, which improves the simplicity of the production device.

[0021] The density of the expanded perlite is small. The rising high-temperature gas makes the perlite with smaller density float more easily, completes the air flotation screening, and is transported to the cooling chamber for cooling through the feeding component after floating. The insufficiently expanded perlite will gradually fall and continue to expand under the high-temperature gas. The expanded perlite is quickly cooled by the cooling component and sent to the stirring device by wind. The automatic feeding component adds zeolite powder, basalt micron fiber, alkali-resistant glass fiber short filaments, condensed silica fume, etc. according to the set dosing rate. After the various raw materials are stirred and mixed evenly in the stirring device and the static electricity is removed, they are transported to the material packaging position, and the mixed materials are packaged by the automatic packaging device, which is convenient for subsequent transportation and storage;

[0022] The expansion chamber should maintain a micro-pressure state to facilitate the rapid evaporation of the water in the perlite to expand the perlite into shape. The gas pressure is the power of expansion. If the pressure in the expansion chamber is too high, the gas in the perlite is difficult to expand and expand the perlite. If the gas pressure in the expansion chamber is too low, the gas in the perlite is easy to escape, the stability is poor, and it is also difficult to expand. Since the expanded perlite is accumulated at the upper end of the expansion chamber, it can effectively reduce heat loss, but it will also cause blockage to the gas in the expansion chamber, resulting in an increase in the pressure in the expansion chamber and a reduction in the expansion efficiency of the perlite. The airflow generated by the cooling component is connected to the expansion chamber. According to the Bernoulli principle, the high-speed airflow in the cooling chamber allows the gas in the expansion chamber to be quickly discharged, reducing the excessive temperature in the expansion chamber caused by the accumulation of expanded perlite in the expansion chamber, thereby ensuring that the expansion chamber is always in a micro-pressure state.

[0023] Based on the above technical solution, the present invention can also be improved as follows.

[0024] Further, the feeding component comprises a material bin and a feeding pipe, the material bin is located at the upper end of the puffing tower, the feeding pipe is installed at the lower side of the material bin, the feeding pipe extends into the puffing chamber and is connected to the rotating component, and the bottom of the feeding pipe has a discharge hole;

[0025] The feeding component is installed on the feeding pipe and close to the discharge end of the expanding chamber.

[0026] The beneficial effect of adopting the above further scheme is: the material bin is used to hold the perlite raw material, the raw material falls into the feed pipe under the action of gravity, the rotating component drives the feed pipe to rotate, and the raw material is thrown out from the discharge hole under the action of centrifugal force to avoid clogging of the discharge hole, and the raw material is evenly scattered on the rotating component.

[0027] Furthermore, the feeding component comprises a feeding spiral blade, the feeding spiral blade is mounted on the feeding pipe, and the upper end of the feeding spiral blade is flush with the discharge end of the expanding chamber.

[0028] The beneficial effect of adopting the above further solution is that the rotation of the rotating assembly drives the feeding pipe to rotate, and then drives the feeding spiral blade to rotate, so as to transport the expanded perlite in the upper layer of the expanding chamber to the cooling chamber.

[0029] Furthermore, the rotating component includes a rotating table and a power motor. The rotating table is installed in the puffing chamber through a supporting bearing. The power motor is installed at the bottom of the puffing tower. The output end of the power motor is connected to the lower end of the rotating table.

[0030] The beneficial effect of adopting the above further solution is that the rotation of the power motor drives the rotating table and the feeding pipe to rotate, which is not only used to throw out the raw materials, but also to transport the expanded perlite to the cooling chamber.

[0031] Further, the high temperature gas component includes a burner, and the burner is connected to the fuel intake pipe and the air supply pipe;

[0032] A heating chamber is provided in the expansion chamber and outside the rotating component. The heating chamber is communicated with the gas outlet end of the burner. An air-permeable net is also installed in the heating chamber.

[0033] The beneficial effect of adopting the above further solution is that the fuel gas and air are burned in the burner to generate high-temperature gas, which is transported to the expansion chamber to expand the raw materials.

[0034] Furthermore, a stirring member is connected to the rotating component, and a stirring end of the stirring member is located in the heating chamber.

[0035] The beneficial effect of adopting the above further solution is that the stirring member is used to stir the raw materials in the heating chamber, so that the raw materials in the heating chamber are heated evenly, thereby improving the puffing efficiency of the raw materials.

[0036] Furthermore, the cooling component includes a cooling fan, and an air outlet of the cooling fan is communicated with the cooling cavity.

[0037] The beneficial effect of adopting the above further scheme is that the expanded perlite is transported to the cooling chamber and cooled under the action of air, which is conducive to rapid shaping and prevents collapse, while improving the physical properties of the perlite.

[0038] Furthermore, a material baffle plate is installed on the feeding pipe, and the material baffle plate is located outside the discharge hole.

[0039] The beneficial effect of adopting the above further solution is that the baffle plate reduces the raw materials being thrown directly into the heating chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Embodiment 1

[0050] like Figure 1 , Figure 2 As shown, a production device for inorganic composite thermal insulation lightweight material includes:

[0051] The puffing tower 1 has a puffing chamber 2. In order to reduce heat loss, the puffing tower 1 adopts a multi-layer insulation tower, and the multi-layer structure is filled with insulation materials.

[0052] A feeding component 3, which is located at the upper side of the puffing tower 1, with a feeding end of the feeding component 3 extending to the bottom of the puffing chamber 2, and a conveying component 4 is installed on the feeding component 3 and close to the upper end of the puffing chamber 2;

[0053] A rotating component 5, which is installed at the bottom of the expanding chamber 2 and is connected to the end of the feeding component 3;

[0054] A high-temperature gas component 6 is installed at the bottom of the puffing tower 1, and a gas outlet end of the high-temperature gas component 6 is communicated with the puffing chamber 2;

[0055] The cooling component 7 has a cooling cavity 8, and the cooling cavity 8 is communicated with the discharge end of the expanding cavity 2.

[0056] A stirring device 21 is installed at the discharge end of the cooling component 7 , and at least one automatic feeding component 22 is installed on the stirring device 21 .

[0057] In the present invention, the perlite raw material is piled in the feeding component 3, and is first transported from the bottom of the feeding component 3 to the rotating component 5 under the action of its own gravity. The rotating component 5 rotates to drive the perlite raw material to rotate and is thrown to the bottom edge of the expanding chamber 2 under the action of centrifugal force. It expands under the continuous action of high-temperature gas. The expanded perlite increases in volume, decreases in density, and continuously accumulates in the expansion chamber. After the expanded perlite accumulates at the upper end of the expanding chamber 2, it is transported to the cooling chamber 8 under the action of the feeding component 4 for rapid cooling, thereby expanding and forming the perlite raw material.

[0058] like Figure 1 ,like Figure 2As shown, in some embodiments, the feeding component 3 includes a material bin 9 and a feeding pipe 10. The material bin 9 is located at the upper end of the puffing tower 1 and is used to temporarily store the perlite raw material. The feeding pipe 10 is installed at the lower side of the material bin 9. An automatic feeding assembly can be installed between the material bin 9 and the feeding pipe 10 to accurately control the feeding rate of the perlite raw material. The feeding pipe 10 extends into the puffing chamber 2 and is connected to the rotating component 5. The bottom of the feeding pipe 10 has a discharge hole. The rotation of the rotating component 5 drives the feeding pipe 10 to rotate, so that the raw material is thrown out from the discharge hole. In order to prevent the raw material from being thrown directly to the periphery of the puffing chamber 2 due to excessive centrifugal force, a baffle plate is also installed on the feeding pipe 10. The baffle plate is located outside the discharge hole. The baffle plate blocks the thrown raw material and drops it onto the rotating component 5 for pretreatment, while reducing the adhesion of the thrown raw material to the puffed perlite.

[0059] In other embodiments, in order to improve the puffing quality of perlite, some relatively dry perlite is soaked in water in advance so that the pores inside the perlite are filled with water, and then the soaked perlite is taken out, drained, and dried, and the surface moisture is removed before adding it to the material bin 9. Limestone, paraffin, adhesives, etc. can also be added to the material bin 9.

[0060] A feeding component 4 is installed on the feeding pipe 10 and near the discharge end of the expanding chamber 2. Specifically, the feeding component 4 includes a feeding spiral blade 11. The feeding spiral blade 11 is installed on the feeding pipe 10, and the upper end of the feeding spiral blade 11 is flush with the discharge end of the expanding chamber 2. The rotating component 5 rotates to drive the feeding pipe 10 and the feeding spiral blade 11 to rotate. The feeding spiral blade 11 rotates to transport the upper layer of perlite with good expansion and low density to the cooling chamber 8.

[0061] In another embodiment, the rotating component 5 includes a rotating table 12 and a power motor 13. The rotating table 12 is connected to the bottom of the feeding pipe 10. The rotating table 12 is installed in the puffing chamber 2 through a supporting bearing. The supporting bearing can be a ceramic bearing. The power motor 13 is installed at the bottom of the puffing tower 1. The output end of the power motor 13 is connected to the lower end of the rotating table 12. The rotation of the power motor 13 drives the rotating table 12 to rotate.

[0062] In the embodiment, the high-temperature gas component 6 includes a burner 14, which is connected to a fuel intake pipe 15 and an air supply pipe 16. The fuel gas and air are transported to the burner 14 and then burned to generate high-temperature gas of 1100°C to 1300°C. The high-temperature gas transfers heat to the pearlite pigment to complete expansion.

[0063] A heating chamber 17 is provided inside the expansion chamber 2 and outside the rotating component 5. The heating chamber 17 is connected to the gas outlet of the burner 14 so that the high-temperature gas is mainly discharged from the heating chamber 17. A breathable net 18 is also installed inside the heating chamber 17. The perlite is originally thrown into the heating chamber 17 under the centrifugal force of the rotating table 12 and is located on the upper side of the breathable net 18. The high-temperature gas enters the heating chamber 17 after passing through the breathable net 18 to expand the perlite pigment in the heating chamber 17. In order to make the perlite raw material in the heating chamber 17 heated evenly and speed up the expansion efficiency, a stirring member 19 is connected to the rotating component 5. The stirring member 19 can be a stirring plate and is connected to the rotating table 12. The stirring end of the stirring member 19 is located inside the heating chamber 17.

[0064] In one embodiment, the cooling component 7 includes a cooling fan 20, the air outlet of the cooling fan 20 is connected to the cooling chamber 8, and the cooling fan 20 conveys external air into the cooling chamber 8, which is not only used to quickly cool the expanded perlite, but also used to blow the expanded perlite into the storage bin.

[0065] The stirring device 21 is installed at the air outlet end of the cooling chamber 8, and the automatic feeding component 22 is used to automatically measure and add silicate anti-seepage cement, zeolite powder, basalt micron fiber, alkali-resistant glass fiber short filaments, condensed silica fume, expanded shale particles, etc., and then the stirring device 21 mixes a variety of inorganic lightweight insulation materials evenly to prepare cement raw materials.

[0066] Embodiment 2

[0067] The only difference between Example 2 and Example 1 is that in Example 2, the cooling chamber 8 consists of an air outlet chamber 23 and an air inlet chamber 24, the air outlet chamber 23 is installed at the air outlet end of the cooling fan 20, and the air inlet chamber 24 is installed at the feeding end of the stirring device 21, the air outlet chamber 23 and the air inlet chamber 24 are arranged opposite to each other and are respectively located on both sides of the outlet end of the puffing chamber 2, the port of the air outlet chamber 23 is flush with the port of the puffing chamber 2, and the port of the air inlet chamber 24 is slightly lower than the port of the puffing chamber 2.

[0068] In the perlite puffing process, after the puffed perlite is output from the puffing chamber 2 through the feeding spiral blade 11, the high-speed airflow ejected from the air outlet chamber 23 blows the puffed perlite into the air inlet chamber 24. During the blowing process, the puffed perlite is not only quickly cooled, but also transported to the stirring device 21 by wind power.

[0069] The high-speed airflow is conducive to forming an air curtain at the port of the puffing chamber 2 to isolate the heat in the puffing chamber 2 and reduce the heat loss in the puffing chamber 2. At the same time, the air curtain makes the pressure in the puffing chamber 21 slightly greater than the external pressure, ensuring that a micro-pressure is formed in the puffing chamber 2 and reducing other impurities from entering from the port of the puffing chamber 2.
