DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Embodiment 1: The present invention designs a silicate inorganic plate dehydration device, and the specific structure is as follows:

[0042] See also Figure 1A plurality of placement layers 101 are fixedly arranged inside the evaporation box 1, and the plurality of placement layers 101 are arranged horizontally and in parallel. The bottommost placement layer 101 and the bottom plate of the evaporation box 1 are the bottommost evaporation layer cavity 102, and the adjacent placement layers 101 are also the evaporation layer cavity 102. The topmost placement layer 101 and the top plate of the evaporation box 1 are the topmost evaporation layer cavity 102, and the silicate inorganic plate 2 is horizontally inserted into the evaporation layer cavity 102.

[0043] The evaporation layer chamber 102 includes an air inlet region 1021 and an air outlet region 1022 . The air inlet region 1021 is located on one side of the silicate inorganic plate 2 , and the air outlet region 1022 is located on the other side of the silicate inorganic plate 2 .

[0044] See also Figure 1 , Figure 3 One end of the main hot air flow pipe 601 is connected to the air outlet end of the main heat device 6, and the main hot air flow pipe 601 is equipped with a first air flow pump 7. The other end of the main hot air flow pipe 601 is connected to the air inlet area 1021 of the evaporation layer cavity 102 at the bottom side.

[0045] The air outlet area 1022 of the evaporation layer cavity 102 at the top side is connected to the humid air flow return pipe 10, the humid air flow return pipe 10 is connected to the air inlet end of the dehumidification equipment 11, the air outlet end of the dehumidification equipment 11 is connected to the dry return pipe 602, and the dry return pipe 602 is connected to the air inlet end of the main heat equipment 6.

[0046] The air outlet of the drying auxiliary device 8 is connected to a drying auxiliary air pipe 801 , the drying auxiliary air pipe 801 is provided with a second air flow pump 9 , and a plurality of independent air flow branches 802 are connected to the drying auxiliary air pipe 801 .

[0047] See also Figure 2 , Figure 3 A one-way valve component 3 is installed at the side end of the placement layer 101, and the one-way valve component 3 connects the two adjacent upper and lower evaporation layer chambers 102. The one-way valve components 3 at the side ends of the two adjacent upper and lower placement layers 101 are distributed at the opposite side ends of the evaporation layer chamber 102 between the two adjacent placement layers 101. This is also easy to understand. The two adjacent upper and lower placement layers 101 form an evaporation layer chamber 102, and the one-way valve components 3 are installed at the side ends of the two adjacent upper and lower placement layers 101, but the two one-way valve components 3 are at the opposite side ends of the evaporation layer chamber 102.

[0048] The gas outlet of the one-way valve component 3 on the upstream side of the evaporation layer chamber 102 at the non-bottom side position faces the gas inlet area 1021 of the evaporation layer chamber 102 , and the gas inlet of the one-way valve component 3 on the downstream side of the evaporation layer chamber 102 at the non-top side position faces the gas outlet area 1022 of the evaporation layer chamber 102 .

[0049] Each evaporation layer chamber 102 is independently equipped with an air pressure monitoring module 4 to detect the air pressure of the evaporation layer chamber 102. The outlet area 1022 of each evaporation layer chamber 102 is equipped with a temperature and humidity sensing module 5 to detect the temperature and humidity of the airflow that is about to leave the outlet area 1022 and enter the next evaporation layer chamber 102.

[0050] The air inlet area 1021 of an evaporation layer chamber 102 is independently connected to an airflow branch pipe 802 . The airflow branch pipe 802 is equipped with a branch pipe electric control valve 803 and an electric heating pipe 804 . The branch pipe electric control valve 803 on the airflow branch pipe 802 is located at the upstream side of the electric heating pipe 804 .

[0051] Embodiment 2: The present invention designs a method for dehydrating silicate inorganic plates, and the specific method contents are as follows:

[0052] Step 1: Open the front panel of the evaporation box 1 and place the silicate inorganic plate 2 in the evaporation layer cavity 102. Figure 1 , Figure 3 In the figure, the evaporation box 1 is a main view cross-sectional view, and an openable sealing cover is provided on the front side plate in the main view direction, so that the silicate inorganic plate 2 can be horizontally placed in the evaporation layer cavity 102. This structure is relatively common, and the detailed features are not drawn and described in the present invention, which does not affect the realization of the technical content of the present invention.

[0053] Step 2: Start the main heating device 6 to inject the main drying hot air flow into the evaporation layer cavity 102 at the bottom of the evaporation box 1.

[0054] Step 3: The main drying hot air flow passes through the air inlet area 1021 of the evaporation layer chamber 102 , passes through the silicate inorganic plate 2 , and reaches the air outlet area 1022 .

[0055] Step 4: The main drying hot air flows through the one-way valve 3 into the evaporation layer chamber 102 at the downstream side, and the contents of step 3 are repeated.

[0056] Step 5: The temperature and humidity sensor module 5 detects the air flow temperature in the outlet area as T x , humidity is R x :

[0057] Case 1: If the temperature T x ≥The system preset minimum drying temperature T min , humidity R x ≤The maximum drying humidity R set by the system max , the airflow branch 802 connected to the evaporation layer chamber 102 at the downstream side is closed. That is, the drying airflow of the evaporation layer chamber 102 at this layer continues to be fully used to continue to heat dry the silicate inorganic board 2 in the evaporation layer chamber 102 at the next layer.

[0058] Case 2: If Tx ≥T min , R x >R max , the branch pipe electric control valve 803 of the air flow branch pipe 802 connected to the evaporation layer chamber 102 at the downstream side is opened, and the electric heating pipe 804 is started:

[0059] The opening degree of the branch pipe electric control valve 803 F(λ)∝humidity difference F(△R), where △R=R x -R max The heating power F(P) of the electric heating tube 804 is equal to the humidity difference F(△R).

[0060] Case 3: If T x <T min , R x ≤R max , the branch pipe electric control valve 803 of the air flow branch pipe 802 connected to the evaporation layer chamber 102 at the downstream side is opened, and the electric heating pipe 804 is started:

[0061] The opening degree of the branch pipe electric control valve 803 F(λ)∝temperature difference F(△T), where △T=T min -T x The heating power F(P) of the electric heating tube 804 is equal to the temperature difference F(△T);

[0062] Case 4: If T x <T min , R x >R max , the branch pipe electric control valve 803 of the air flow branch pipe 802 connected to the evaporation layer chamber 102 at the downstream side is opened, and the electric heating pipe 804 is started:

[0063] The opening degree F(λ) of the branch pipe electric control valve 803 is ∝[F(△R)*F(△T)]. The heating power F(P) of the electric heating tube 804 is ∝[F(△R)*F(△T)]. This is also easy to understand. When the temperature and humidity are not up to standard, the opening degree λ of the branch pipe electric control valve 803 and the heating power P of the electric heating tube 804 are controlled according to the common factors of the temperature difference and the humidity difference.

[0064] Step six, when the air pressure monitoring module 4 detects that the air pressure of the evaporation layer chamber 102 at the current position is higher than the air pressure of the evaporation layer chamber 102 on the upstream side, the branch pipe electric control valve 803 and the electric heating tube 804 of the air flow branch pipe 802 connected to the evaporation layer chamber 102 at the current position are closed. When the air pressure of the evaporation layer chamber 102 at the current position is not higher than the air pressure of the evaporation layer chamber 102 on the upstream side, according to the temperature and humidity requirements in the above steps, the opening degree of the branch pipe electric control valve 803 and the heating power of the electric heating tube 804 can be continued to be controlled.

[0065] Note: When the temperature rises, the air can hold more water vapor, so the relative humidity will decrease. Conversely, when the temperature decreases, the amount of water vapor that the air can hold decreases, and the relative humidity will increase. The present invention controls the total amount of drying gas and the temperature of the airflow to regulate the drying environment of the silicate inorganic board, so as to ensure that the drying environment of the silicate inorganic board meets the standards.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
