Description

Technical Field

[0001] This utility model relates to the field of calcium silicate board processing, and in particular to a low-energy-consumption autoclaving device for calcium silicate boards. Background Technology

[0002] Calcium silicate board is a new type of inorganic board material made primarily from siliceous and calcareous materials, with added fiber reinforcement and additives, through processes such as pulping, molding, and autoclaving. Its core characteristics are high strength and excellent fire resistance, along with good moisture resistance, sound insulation, and anti-aging properties. It also contains no formaldehyde or other harmful substances, making it an environmentally friendly building material. During the autoclaving stage of calcium silicate board production, an autoclaving device is typically used.

[0003] In related technologies, the processing of calcium silicate slab blanks mainly relies on autoclaving to improve the strength, density, and durability of the slab. Traditional autoclaving devices typically consist of an autoclave, a steam generation system, a pressure control system, and a temperature control system. The autoclave is usually a cylindrical pressure vessel, and a support plate is usually installed inside the autoclave to support the calcium silicate slab blank. During use, the operator sends the formed slab blank into the autoclave, then introduces high-pressure steam and maintains the set temperature and pressure for a period of time. After curing, the pressure and temperature are slowly reduced, and finally the cured slab is output.

[0004] However, the steam entry point of traditional autoclaving devices may be relatively concentrated, which may affect the uniformity of autoclaving on calcium silicate boards.

[0005] Therefore, it is necessary to provide a low-energy-consumption autoclaving device for calcium silicate boards to solve the above problems. Utility Model Content

[0006] To address the technical problem that the steam inlet of traditional autoclaving devices may be concentrated, which could affect the uniformity of autoclaving of calcium silicate boards, this invention provides a low-energy-consumption autoclaving device for calcium silicate boards.

[0007] This utility model provides a low-energy-consumption autoclaving device for calcium silicate boards, comprising: an autoclave, wherein the bottom inner wall of the autoclave has a ventilation cavity, and multiple air holes evenly distributed on the bottom of the inner wall of the autoclave are connected to the ventilation cavity; heat preservation cavities are formed on both sides of the inner wall of the autoclave; multiple connecting holes evenly distributed on the top of the inner wall of the autoclave are connected to the heat preservation cavities; a water collection tank is formed on the bottom of the inner wall of the autoclave; the multiple air holes are evenly distributed on both sides of the water collection tank; an air supply pipe; an exhaust assembly; and a drain pipe, wherein the air supply pipe is fixedly installed. At one end of the steam curing vessel, and connected to the ventilation chamber, there are two exhaust assemblies, which are symmetrically fixed at the bottom of the steam curing vessel. The top of each exhaust assembly is connected to each of the insulation chambers. The drain pipe is fixed at one end of the steam curing vessel and connected to the water collection tank. There are two support rails, which are symmetrically fixed at the bottom of the inner wall of the steam curing vessel. A perforated support plate is provided above the symmetrically arranged support rails, and the air hole is located below the perforated support plate.

[0008] Preferably, a plurality of hemispherical jet nozzles are uniformly fixedly connected to the bottom of the inner wall of the steam curing vessel, and each hemispherical jet nozzle is connected to each of the air holes.

[0009] Preferably, a first insulation layer is fixedly connected inside the heat preservation cavity, and a second insulation layer is fixedly connected inside the air vent cavity.

[0010] Preferably, the interior of the steam curing vessel is uniformly and fixedly connected with a plurality of first reinforcing columns located inside the heat preservation cavity, and the interior of the steam curing vessel is uniformly and fixedly connected with a plurality of second reinforcing columns located inside the ventilation cavity.

[0011] Preferably, a plurality of rollers are evenly arranged below the perforated support plate. The rollers are located on the upper surface of the support track. Ear plates are rotatably connected to both sides of the rollers. The upper surface of the ear plates is fixedly connected to the lower surface of the perforated support plate. Limiting ring plates are fixedly connected to the outer walls of both sides of the rollers. The limiting ring plates are located on one side of the support track.

[0012] Preferably, the exhaust assembly includes an exhaust pipe, the top of which is uniformly and fixedly connected to a plurality of connecting pipes, the top of which passes through the steam curing vessel and is connected to the heat preservation cavity.

[0013] Compared with related technologies, the low-energy-consumption autoclaving device for calcium silicate boards provided by this utility model has the following beneficial effects:

[0014] 1. This low-energy-consumption calcium silicate board autoclaving device can improve the uniformity of autoclaving of calcium silicate boards: external steam is stably delivered to the ventilation chamber through the set air supply pipe. After the ventilation chamber initially disperses the steam, the steam is evenly delivered to the inside of the autoclave through the evenly arranged air holes and hemispherical jet nozzles, so as to prevent the steam from rushing in. This allows the steam to act evenly on the bottom and sides of the calcium silicate board blank on the perforated support plate, thereby improving the uniformity of autoclaving of calcium silicate boards.

[0015] 2. This low-energy calcium silicate board autoclaving device has insulation chambers on both sides of the autoclave, and a connecting hole at the top allows excess gas in the autoclave to enter the insulation chamber, forming a slight airflow exchange. The residual heat is used to enhance the insulation effect and balance the temperature inside the autoclave. At the same time, the first and second insulation layers are located on the outer walls of the insulation chamber and the ventilation chamber, respectively, which can prevent heat from the autoclave from being transferred to the outside, further improving the insulation performance of the autoclave and reducing energy consumption during use.

[0016] 3. This low-energy calcium silicate board autoclaving device enhances the structural strength of the internal insulation and ventilation chambers of the autoclave through the installation of the first and second reinforcing columns. This prevents problems such as chamber deformation and collapse under long-term high-temperature and high-pressure operation, thereby extending the service life of the device. Rollers, ear plates, and limiting ring plates are installed below the perforated support plate. The ear plates restrict the installation position of the rollers, and the limiting ring plates restrict the movement of the rollers on the support track, so as to facilitate the movement of the perforated support plate by personnel, thereby improving the convenience and efficiency of operation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 4 A low-energy-consumption autoclaving device for calcium silicate boards includes: an autoclave 1, a ventilation cavity 2 formed on the bottom inner wall of the autoclave 1, multiple air holes 3 evenly distributed on the bottom inner wall of the autoclave 1 and connected to the ventilation cavity 2, heat preservation cavities 4 formed on both sides of the inner wall of the autoclave 1, multiple connecting holes 5 evenly distributed on the top inner wall of the autoclave 1 and connected to the heat preservation cavities 4, a water collection tank 6 formed on the bottom inner wall of the autoclave 1, multiple air holes 3 evenly distributed on both sides of the water collection tank 6, an air supply pipe 7, an exhaust assembly 8, and a drain pipe 9, wherein the air supply pipe 7 is fixedly installed. At one end of the steam curing vessel 1, and connected to the ventilation chamber 2, there are two exhaust components 8. The two exhaust components 8 are symmetrically fixed at the bottom of the steam curing vessel 1. The top of each exhaust component 8 is connected to each insulation chamber 4. The drain pipe 9 is fixed at one end of the steam curing vessel 1 and connected to the water collection tank 6. There are two support rails 10. The two support rails 10 are symmetrically fixed at the bottom of the inner wall of the steam curing vessel 1. A perforated support plate 11 is provided above the symmetrically arranged support rails 10. The air hole 3 is located below the perforated support plate 11.

[0024] In the specific implementation process, the autoclave 1 in this low-energy calcium silicate board autoclaving device is the core pressure vessel of the device. A ventilation chamber 2 is formed on the inner wall of the bottom of the autoclave 1, and the ventilation chamber 2 is elongated and distributed along the length of the autoclave 1 to initially disperse the incoming steam. Simultaneously, multiple air holes 3, connected to the ventilation chamber 2, are evenly formed on the bottom of the inner wall of the autoclave 1. These air holes 3 are arranged in a matrix to evenly transport the steam in the ventilation chamber 2 into the interior of the autoclave 1, preventing concentrated steam intrusion. Furthermore, heat insulation chambers 4 are formed on both sides of the inner wall of the autoclave 1, and the top of the inner wall of the autoclave 1 is also evenly formed... Multiple connecting holes 5 are provided, which are connected to the heat preservation cavity 4. Excess gas inside the steam curing kettle 1 can be transported into the heat preservation cavity 4 through the connecting holes 5, thereby enabling a slight airflow exchange between the heat preservation cavity 4 and the space inside the kettle. At the same time, the residual heat can be utilized to enhance the heat preservation effect of the heat preservation cavity 4, further balance the temperature inside the kettle, and reduce energy consumption during use. A water collection tank 6 is also provided at the bottom of the inner wall of the steam curing kettle 1. The water collection tank 6 is located in the middle of the bottom of the inner wall, and multiple air holes 3 are evenly distributed on both sides of the water collection tank 6. The water collection tank 6 can collect the condensate generated during the curing process in a timely manner to prevent water accumulation from affecting the steam distribution.

[0025] Furthermore, a gas supply pipe 7 connected to the ventilation chamber 2 is fixedly connected to one end of the steam curing vessel 1. The high-pressure steam generated by the external steam generation system can be stably delivered to the ventilation chamber 2 through the gas supply pipe 7. Two exhaust components 8 are fixedly connected to the bottom of the steam curing vessel 1, which are respectively connected to each heat preservation chamber 4. The two exhaust components 8 can discharge excess gas inside the heat preservation chamber 4, thereby balancing the pressure inside the steam curing vessel 1. A drain pipe 9 connected to the water collection tank 6 is fixedly connected to one end of the steam curing vessel 1. The condensate collected in the water collection tank 6 can be discharged in time through the drain pipe 9 to ensure the normal operation of the device.

[0026] Furthermore, two support rails 10 are symmetrically fixedly installed at the bottom of the inner wall of the steam curing kettle 1. The perforated support plate 11 can be supported by the symmetrically arranged support rails 10. The calcium silicate board blank is placed on the perforated support plate 11. The vent 3 is located below the perforated support plate 11. The steam discharged from the vent 3 can pass through the vent holes of the perforated support plate 11 and act evenly on the bottom and sides of the blank, so that each blank can fully contact the steam, thereby improving the uniformity of the steam curing effect on the calcium silicate board.

[0027] Specifically, the support track 10 consists of a track and multiple pillars fixed between the lower surface of the track and the bottom of the inner wall of the steam curing vessel 1. The perforated support plate 11 has multiple air vents evenly distributed on its surface.

[0028] See Figure 2 and Figure 3 As shown, multiple hemispherical jet nozzles 12 are uniformly fixedly connected to the bottom of the inner wall of the steam curing vessel 1, and each hemispherical jet nozzle 12 is connected to each air hole 3.

[0029] In the specific implementation process, the hemispherical jet head 12 can play a certain protective role at the air hole 3 to prevent the liquid sliding down the inner wall of the steam curing kettle 1 from flowing into the air hole 3.

[0030] See Figure 2 and Figure 3 As shown, the steam curing vessel 1 is fixedly connected to a first insulation layer 13 located inside the insulation cavity 4, and the steam curing vessel 1 is fixedly connected to a second insulation layer 14 located inside the ventilation cavity 2.

[0031] In the specific implementation process, the first insulation layer 13 is located on the outer wall of the insulation cavity 4, and the second insulation layer 14 is located on the outer wall of the ventilation cavity 2. The insulation performance of the steam curing kettle 1 can be further improved and energy loss can be reduced through the first insulation layer 13 and the second insulation layer 14.

[0032] Specifically, it should be noted that both the first insulation layer 13 and the second insulation layer 14 can be made of composite insulation materials, such as a superimposed structure of aluminum silicate fiber felt and polyurethane insulation board, so as to prevent heat from being transferred from inside the vessel to the outside.

[0033] See Figure 2 and Figure 3 As shown, several first reinforcing columns 15 are uniformly fixedly connected inside the heat preservation cavity 4, and several second reinforcing columns 16 are uniformly fixedly connected inside the ventilation cavity 2.

[0034] In the specific implementation process, by setting up several first reinforcing columns 15 and several second reinforcing columns 16, the structural strength of the internal heat preservation cavity 4 and ventilation cavity 2 of the steam curing kettle 1 can be enhanced to prevent the cavity from deforming or collapsing under long-term high temperature and high pressure operation, thereby improving the overall structural stability of the steam curing kettle 1 and extending the service life of the device.

[0035] See Figure 2 , Figure 3 and Figure 4 As shown, a plurality of rollers 17 are evenly arranged below the perforated support plate 11. The rollers 17 are located on the upper surface of the support rail 10. Ear plates 18 are rotatably connected to both sides of the rollers 17. The upper surface of the ear plates 18 is fixedly connected to the lower surface of the perforated support plate 11. Limiting ring plates 19 are fixedly connected to the outer walls on both sides of the rollers 17. The limiting ring plates 19 are located on one side of the support rail 10.

[0036] In the specific implementation process, the ear plate 18 can limit the installation position of the roller 17 at the bottom of the perforated support plate 11, and the limiting ring plate 19 can limit the movement position of the roller 17 on the support track 10, thereby facilitating the movement of the perforated support plate 11 by personnel.

[0037] See Figure 1 and Figure 2 As shown, the exhaust assembly 8 includes an exhaust pipe 801, and a plurality of connecting pipes 802 are uniformly fixedly connected to the top of the exhaust pipe 801. The top of the connecting pipes 802 penetrates the steam curing kettle 1 and is connected to the heat preservation cavity 4.

[0038] In the specific implementation process, the excess gas inside the insulation cavity 4 can be transported into the exhaust pipe 801 through multiple connecting pipes 802, and the excess gas can be transported or discharged through the exhaust pipe 801.

[0039] The working principle of the low-energy calcium silicate board autoclaving device provided by this utility model is as follows:

[0040] When the low-energy calcium silicate board autoclaving device is working, the high-pressure steam generated by the external steam generation system is transported to the ventilation chamber 2 at the bottom of the autoclave 1 through the air supply pipe 7. The ventilation chamber 2 is long and distributed along the length of the autoclave 1, which initially disperses the steam. Then, the steam is evenly transported to the interior of the autoclave 1 through multiple air holes 3 that are evenly distributed at the bottom of the inner wall of the autoclave 1 and connected to the ventilation chamber 2, and passes through the hemispherical jet nozzle 12. It then passes through the perforated support plate 11 and acts on the bottom and sides of the calcium silicate board blank placed on it.

[0041] Excess gas in the steam curing kettle 1 enters the insulation chambers 4 on both sides through the top connecting hole 5. Excess gas in the insulation chamber 4 is discharged through the connecting pipe 802 of the exhaust assembly 8 into the exhaust pipe 801, balancing the pressure inside the kettle. The condensate generated during the curing process flows into the water collection tank 6 at the bottom center of the inner wall of the steam curing kettle 1 and is discharged in time through the drain pipe 9. The first insulation layer 13 and the second insulation layer 14 are located on the outer walls of the insulation chamber 4 and the ventilation chamber 2, respectively, which can reduce heat loss. The first reinforcing column 15 and the second reinforcing column 16 can enhance the structural strength of the insulation chamber 4 and the ventilation chamber 2.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
