Description

Technical Field

[0001] This utility model relates to the field of board processing technology, and more specifically, it relates to an inorganic cold-pressed fiberboard curing room structure. Background Technology

[0002] In the production of inorganic cold-pressed fiberboard, the curing process is crucial. A suitable humidity environment has a decisive impact on the physical properties, dimensional stability, and bonding strength of the inorganic fiberboard. Traditional humidification methods, such as spray humidification, easily lead to uneven moisture distribution, with some fiberboards becoming excessively damp while others are under-humidified, affecting product quality consistency. Steam humidification, on the other hand, suffers from high energy consumption, complex equipment, and the tendency to form condensation in the curing room, increasing production costs and potentially causing secondary damage to the fiberboard. Furthermore, existing humidification systems often struggle to precisely control humidity, failing to meet the stringent humidity requirements of inorganic cold-pressed fiberboard at different curing stages.

[0003] Chinese patent application number 2019112597001 discloses a humidification device for fiberboard production. It uses a micro water pump to draw water into a hose, and adjusts a solenoid valve to allow water to be smoothly drawn into the inner side of a connecting pipe. The connecting pipe then draws the water into a humidification nozzle, which sprays the water onto the inside of the humidification box to humidify the fiberboard. This spray-type humidification method is prone to uneven moisture distribution, with some fiberboard becoming excessively damp while others are under-humidified, affecting the consistency of product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a curing room structure for inorganic cold-pressed fiberboard, which provides uniform humidification and precise humidity control during the curing process of inorganic cold-pressed fiberboard. The structure is simple and the cost is low.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an inorganic cold-pressed fiberboard curing chamber structure, wherein several water mist nozzles are installed on the top of the curing chamber, and air curtain generating strips that spray downward air curtains are installed on both sides of the water mist nozzles. Multiple humidity detectors are installed inside the curing chamber, and the humidity detectors are arranged in multiple positions. The water mist nozzles are connected to a water mist generator, and the water mist generator is provided with an air inlet pipe and a water inlet pipe. The water mist generator is provided with a water inlet chamber, a mixing chamber, and an outlet chamber. The end of the air inlet pipe faces the mixing chamber, the water inlet pipe is connected to the water inlet chamber, and the water mist nozzles are connected to the outlet chamber.

[0006] During the curing of inorganic cold-pressed fiberboard, the fiberboard is loaded onto the mounting frame, which is then pushed into the curing chamber, and the roller shutter door is closed. The water mist generator is then activated, and a high-pressure airflow is injected from the air inlet pipe into the mixing chamber, creating negative pressure in the water inlet chamber. Water from the inlet pipe is drawn into the water inlet chamber, where the airflow and water flow mix to form water vapor, achieving an atomization effect. Finally, the vapor is sprayed into the curing chamber through the outlet chamber from the water mist nozzles. The water mist nozzles are installed on the top of the curing chamber, and the sprayed water mist is projected downwards from the top, allowing the mist to diffuse to all areas of the curing chamber. Air curtain generating strips are installed on both sides of the water mist nozzles, spraying downwards to create an air curtain that blocks the water mist from the nozzles, preventing it from directly hitting the fiberboard and causing excessive moisture residue, which would affect the curing effect. Furthermore, the air curtain can further disperse the water mist, allowing it to flow to various locations within the curing chamber, thus improving the uniformity of water mist distribution and consequently enhancing the uniformity of humidification of fiberboard in different locations.

[0007] Humidity detectors are installed in multiple locations within the curing room to monitor humidity levels at different locations. The monitored data is used to control the on / off state of water mist generators at these locations, thereby ensuring more uniform humidity distribution and achieving precise humidity control.

[0008] The inorganic cold-pressed fiberboard curing chamber structure of this application ensures uniform humidification and precise humidity control during the curing process of inorganic cold-pressed fiberboard. It is also simple in structure and low in cost.

[0009] As a preferred option, an electromagnetic control valve is installed on the air intake pipe; and a flow regulating valve is installed on the water intake pipe.

[0010] The air inlet pipe is controlled by an electromagnetic control valve, which facilitates the control of the water mist generator. The flow regulating valve controls the flow of water in the inlet pipe, thereby controlling the moisture content of the water mist sprayed from the nozzles and further regulating the humidity inside the curing chamber.

[0011] Preferably, several turbulence plates are installed on the inner wall of the outflow cavity, and the turbulence plates are arranged in a circumferential spiral.

[0012] The circumferential spiral design of the turbulence plate creates turbulence in the water mist within the outlet cavity, improving the mixing effect of water and airflow and enhancing the atomization effect of the water mist.

[0013] Preferably, the inner diameters of the inlet chamber and the outlet chamber are both larger than the inner diameter of the mixing chamber, and a funnel-shaped transition chamber is provided between the inlet chamber and the mixing chamber, as well as between the mixing chamber and the outlet chamber.

[0014] With a smaller inner diameter of the mixing chamber, negative pressure is more easily generated in the inlet chamber after the airflow is injected into it. Conversely, the increased size of the outlet chamber reduces pressure, which improves the water-air mixing effect.

[0015] Preferably, several guide plates are arranged circumferentially on the inner wall of the mixing chamber, and the guide plates are bent to form a wave-shaped structure.

[0016] The wavy guide vane is placed inside the mixing chamber. When the water flows into the guide vane, it is dispersed, improving the atomization effect. Furthermore, the wavy guide vane creates turbulence in the fluid, resulting in a more uniform mixing of water and air.

[0017] Preferably, several guide strips are arranged circumferentially on the inner wall of the water mist nozzle opening, with the width of the guide strips gradually increasing towards the water mist nozzle opening.

[0018] A guide strip is installed on the inner wall of the water mist nozzle opening to divide the sprayed water mist into multiple streams. These multiple streams of water mist can collide with each other, improving the dispersion effect.

[0019] Another option is to install a conical guide head at the opening end of the water mist nozzle, forming a spray gap between the end of the guide head and the opening end of the water mist nozzle, and connecting several circumferentially spaced mixing plates between the guide head and the inner wall of the water mist nozzle.

[0020] A spray gap is formed between the conical guide head and the inner wall of the water mist nozzle, thus spraying out annular water mist with good diffusion effect. Furthermore, the mixing plate is set between the guide head and the inner wall of the water mist nozzle, creating a turbulent effect in the water mist at this location and improving the uniformity of water mist mixing.

[0021] As a preferred option, an atomizing mesh plate is installed inside the water mist nozzle.

[0022] The atomizing mesh plate is installed inside the water mist nozzle to improve the atomization effect.

[0023] As a preferred option, an air curtain generating strip is installed on the inner wall of the curing chamber near the top, and the air curtain generating strip sprays an air curtain parallel to the inner wall of the curing chamber downwards.

[0024] The air curtain generating strip sprays downwards, creating an air curtain parallel to the inner wall of the curing chamber, preventing droplets from contacting the inner wall and avoiding condensation.

[0025] As a preferred option, a rotating dispersing impeller is installed inside the curing chamber, positioned below the water mist nozzle.

[0026] The water mist sprayed from the water mist nozzle blows and disperses the impeller as it rotates, thus dispersing the water mist and making the water mist more evenly distributed throughout the curing room.

[0027] Compared with the prior art, the beneficial effects of this utility model are: (1) The inorganic cold-pressed fiberboard curing room structure of this application makes the humidification uniform and the humidity control precise during the curing process of inorganic cold-pressed fiberboard. The structure is simple and the cost is low; (2) The water mist generator can generate a turbulent effect, which improves the uniformity of water mist mixing; (3) The air curtain is sprayed in the curing room. The air curtain and water mist collide with each other, which further improves the dispersion effect, making the humidity in each position in the curing room more uniform, preventing the local humidity from being too high and causing water droplets to damage the fiberboard.

[0034] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1: A structure for an inorganic cold-pressed fiberboard curing room (see...) Figure 1 , Figure 2 , Figure 3A door is installed on one side of the curing chamber 1, with a roller shutter door at the door. Several water mist nozzles 2 are installed on the top of the curing chamber 1. A row of water mist nozzles is spaced apart in the middle of the curing chamber 1. Air curtain generating strips 3 are installed on both sides of the water mist nozzles 2, spraying downwards to create an air curtain. The air curtain blocks the water mist sprayed from the water mist nozzles 2, preventing water mist from directly spraying onto the fiberboard and causing excessive moisture residue on the fiberboard, which would affect the curing effect. Air curtain generating strips 3 are installed on the inner wall of the curing chamber 1 near the top, spraying downwards to create an air curtain parallel to the inner wall of the curing chamber 1. The downward spraying of the air curtain generating strips 3 parallel to the inner wall of the curing chamber 1 prevents droplets from contacting the inner wall of the curing chamber 1 and avoids water droplet condensation on the inner wall of the curing chamber 1.

[0035] An elongated air storage chamber 4 and an elongated air inlet hole 5 are provided on the air curtain generating strip 3. Several vent holes are axially spaced on the inner wall of the elongated air inlet hole 5, which connect the air storage chamber 4 and the elongated air inlet hole 5. An air curtain generating groove 6 is provided on the lower surface of the air curtain generating strip 3, which is connected to the air storage chamber 4. The bottom of the air storage chamber 4 has a V-shaped structure. A blower 7 is installed on the top of the curing chamber 1, and the elongated air inlet hole 5 is connected to the air outlet of the blower 7 through a pipe.

[0036] Multiple humidity detectors 8 are installed inside the curing chamber 1, located in various positions. Humidity detectors 8 are installed on the upper and lower parts of each inner wall of the curing chamber 1. These detectors detect the humidity at different locations within the curing chamber 1 and control the on / off state of the water mist generators 9 at these locations based on the detected data. This ensures more uniform humidity distribution within the curing chamber 1 and achieves precise humidity control. The water mist nozzle 2 is connected to the water mist generator 9. The water mist generator 9 is equipped with an air inlet pipe 10 and a water inlet pipe 11, which are arranged vertically and coaxially with the water mist generator 9. The water mist generator 9 is equipped with a water inlet chamber 12, a mixing chamber 13, and an outlet chamber 14. The mixing chamber 13 is located between the water inlet chamber 12 and the outlet chamber 14. The end of the air inlet pipe 10 has a tapered structure and faces the mixing chamber 13. The water inlet pipe 11 is connected to the water inlet chamber 12, and the water mist nozzle 2 is connected to the outlet chamber 14. The inner diameters of the water inlet chamber 12 and the outlet chamber 14 are both larger than the inner diameter of the mixing chamber 13. A funnel-shaped transition chamber 15 is provided between the water inlet chamber 12 and the mixing chamber 13, and between the mixing chamber 13 and the outlet chamber 14.

[0037] Several turbulence plates 16 are installed on the inner wall of the outlet cavity 14, and the turbulence plates 16 are arranged in a circumferential spiral. The circumferential spiral arrangement of the turbulence plates 16 causes turbulence in the water mist within the outlet cavity 14, which improves the mixing effect of water and airflow and enhances the atomization effect of the water mist.

[0038] Several guide strips 17 are arranged circumferentially at intervals on the inner wall of the opening end of the water mist nozzle 2, with the width of the guide strips 17 gradually increasing towards the opening end of the water mist nozzle 2. An atomizing mesh plate 18 is installed inside the water mist nozzle 2. The guide strips 17 on the inner wall of the opening end of the water mist nozzle 2 cause the sprayed water mist to be divided into multiple streams, which can collide with each other, improving the dispersion effect. The atomizing mesh plate 18 is installed inside the water mist nozzle 2 to improve the atomization effect.

[0039] An air inlet pipe 10 is connected to a blower 7 via a pipe, and a water inlet pipe 11 is connected to a water tank via a pipe. An electromagnetic control valve 19 is installed on the air inlet pipe 10; a flow regulating valve 20 is installed on the water inlet pipe 11. The electromagnetic control valve 19 controls the on / off state of the air inlet pipe 10, facilitating the control of the water mist generator 9. The flow regulating valve 20 controls the flow in the water inlet pipe 11, thereby controlling the moisture content in the water mist sprayed from the water mist nozzle 2, further regulating the humidity inside the curing chamber 1.

[0040] During the curing of inorganic cold-pressed fiberboard, the fiberboard is loaded onto the mounting frame 21, and then the mounting frame 21 is pushed into the curing chamber 1, and the roller shutter door is closed. Then, the water mist generator 9 is activated, and high-pressure airflow is injected from the air inlet pipe 10 into the mixing chamber 13, thereby creating negative pressure in the water inlet chamber 12. The water flow in the water inlet pipe 11 is drawn into the water inlet chamber 12, and the airflow and water flow mix in the mixing chamber 13, forming water vapor and achieving an atomization effect. Finally, the vapor is sprayed into the curing chamber 1 through the outlet chamber 14 from the water mist nozzle 2. The water mist nozzle 2 is installed on the top of the curing chamber 1, and the sprayed water mist is sprayed downwards from the top of the curing chamber 1, allowing the mist to diffuse to all positions in the curing chamber 1. Air curtain generating strips 3 are installed on both sides of the water mist nozzle 2. The air curtain generating strips 3 spray downwards, blocking the water mist sprayed from the water mist nozzle 2 and preventing the water mist from directly spraying onto the fiberboard, resulting in excessive moisture residue on the fiberboard and affecting the curing effect. Furthermore, the air curtain can further disperse the water mist, allowing it to flow to various locations within the curing chamber 1, thereby improving the uniformity of water mist distribution within the curing chamber 1 and thus enhancing the uniformity of humidification of fiberboard in different locations.

[0041] A controller is installed on curing chamber 1. Humidity detector 8, blower 7, solenoid control valve 19, and flow regulating valve 20 are all electrically connected to the controller. The humidity data detected by humidity detector 8 at various locations within curing chamber 1 are transmitted to the controller. The controller analyzes the detected data and controls blower 7, solenoid control valve 19, and flow regulating valve 20 to ensure that the humidity value within curing chamber 1 reaches the set requirement.

[0042] Example 2: A structure for an inorganic cold-pressed fiberboard curing room (see...)

The air curtain blocks the water mist sprayed from the water mist nozzles 2, preventing water mist from directly spraying onto the fiberboard and causing excessive moisture residue on the fiberboard, which would affect the curing effect. Air curtain generating strips 3 are installed on the inner wall of the curing chamber 1 near the top, spraying downwards to create an air curtain parallel to the inner wall of the curing chamber 1. The downward spraying of the air curtain generating strips 3 parallel to the inner wall of the curing chamber 1 prevents droplets from contacting the inner wall of the curing chamber 1 and avoids water droplet condensation on the inner wall of the curing chamber 1.

[0043] An elongated air storage chamber 4 and an elongated air inlet hole 5 are provided on the air curtain generating strip 3. Several vent holes are axially spaced on the inner wall of the elongated air inlet hole 5, which connect the air storage chamber 4 and the elongated air inlet hole 5.

The bottom of the air storage chamber 4 has a V-shaped structure. A blower 7 is installed on the top of the curing chamber 1, and the elongated air inlet hole 5 is connected to the air outlet of the blower 7 through a pipe.

[0044] Multiple humidity detectors 8 are installed inside the curing chamber 1, located in various positions. Humidity detectors 8 are installed on the upper and lower parts of each inner wall of the curing chamber 1.

A bracket 23 is installed in the middle of the curing chamber 1, and the dispersing impeller 22 is rotatably mounted on the upper part of the bracket 23. The water mist sprayed from the water mist nozzle 2 drives the dispersing impeller 22 to rotate, dispersing the water mist during rotation and making the water mist distribution more uniform throughout the curing chamber 1.

[0049] During the curing of inorganic cold-pressed fiberboard, the fiberboard is loaded onto the mounting frame 21, and then the mounting frame 21 is pushed into the curing chamber 1, and the roller shutter door is closed. Then, the water mist generator 9 is activated, and high-pressure airflow is injected from the air inlet pipe 10 into the mixing chamber 13, thereby creating negative pressure in the water inlet chamber 12.
