[0002] Calcium silicate board is a new generation of "green" building materials. It has unique environmental protection functions based on excellent moisture-proof and fire-proof properties. Calcium silicate board is made of silicon powder and calcium powder as the main base material, natural wood fiber as the reinforcing material, and other auxiliary materials. After slurry forming, it is placed in an autoclave curing tank for high temperature and high pressure curing, thus generating a new type of building material, calcium silicate board;

[0025] Preferably, a slide groove 24 is provided on the lower end surface of the tank body 1; a slide plate 241 is slidably connected in the slide groove 24; a jet port 242 connected to the slide groove 24 is provided on the surface of the slide plate 241; an air bag 25 is provided between the slide plate 241 and the groove wall of the slide groove 24; one end of the air bag 25 is fixedly connected to the slide plate 241; and the other end is fixedly connected to the groove wall of the slide groove 24; the air bag 25 is connected to the mounting groove 2.

[0026] Preferably, a rotating rod 26 is rotatably connected in the slide groove 24; two spiral grooves 261 in opposite directions are opened on the surface of the rotating rod 26; the two spiral grooves 261 are connected to each other; and the rotating rod 26 is connected to the slide plate 241 through a spiral transmission.

[0027] Preferably, a groove 27 is formed at the upper end of the rotating rod 26; a rotating wheel 271 is rotatably connected in the groove 27; a cavity 272 connected to the air jet 242 is formed inside the rotating wheel 271; and an air hole 273 connected to the cavity 272 is formed on the surface of the rotating wheel 271.

[0028] Preferably, the air holes 273 are arranged at an angle; and the rotating wheel 271 is made of PTFE material.

[0029] Preferably, a water storage tank 16 is provided at the lower end surface of the tank body 1; the water storage tank 16 is connected to the mounting tank 2; a one-way valve 161 is fixedly installed in the water storage tank 16; a drain port 17 connected to an external drain pipe is provided at the lower end of the water storage tank 16; a solenoid valve 171 is fixedly installed in the drain port 17;

[0030] When the existing autoclave curing tank is autoclaving the calcium silicate board, it is necessary to transport high-temperature steam into the autoclave curing tank through the air inlet 11 at the upper end of the autoclave curing tank. Since the hot air flow has the characteristic of natural rise, when the high-temperature steam enters the tank through the air inlet 11, the high-temperature steam will rise rapidly and concentrate in the upper area of ​​the autoclave curing tank, making the temperature distribution of the upper and lower areas of the autoclave curing tank uneven, making the lower area of ​​the autoclave curing tank insufficient due to the lower temperature, thereby affecting the curing effect of the calcium silicate board; reducing the hardness, strength and other performance indicators of the calcium silicate board;

[0031] During operation, the user opens the cover 14, and then pushes the conveying rack loaded with the calcium silicate board into the autoclave curing tank through the feed port 13, and then closes the cover 14. At this time, the high-temperature steam is controlled to enter the autoclave curing tank through the air inlet 11; at the same time, the driving motor 23 is controlled to operate, so that the driving motor 23 and the worm 222 are connected by a belt drive through a transmission belt; the driving motor 23 can drive the worm 222 to rotate, so that the worm 222 drives the worm wheel 221 meshing with it to rotate, and then the worm wheel 221 drives the blade 21 fixed to it to rotate, so that the blade 21 can discharge the gas in the installation groove 2 during the rotation process. The air in the air intake port 15 enters the mounting groove 2, so that the air in the air intake port 15 enters the mounting groove 2, so that the air in the air intake port 15 is in a negative pressure state, so that the steam in the upper end area of ​​the autoclave curing tank can be sucked in by the air intake port 15 and transported to the mounting groove 2, so that the blades 21 in the mounting groove 2 transport the sucked steam to the air bag 25 in the chute 24, so that the steam entering the air bag 25 can be ejected through the jet port 242 of the slide plate 241, so that the ejected gas can rise to the upper area of ​​the autoclave curing tank again, so that the high-temperature steam can circulate in the autoclave curing tank, and the temperature consistency of the upper and lower areas in the autoclave curing tank is ensured;

[0032] Steam is ejected from the air jet 242 of the slide plate 241, so that the temperature of the lower area of ​​the autoclave curing tank near the air jet 242 of the slide plate 241 is high, while the temperature of the area far from the air jet 242 of the slide plate 241 is low. Therefore, in order to improve the temperature uniformity of the lower area of ​​the autoclave curing tank in the lateral direction, the utility model is provided with a rotating rod 26, so that the driving motor 23 drives the rotating rod 26 to rotate, so that the rotating rod 26 drives the slide plate 241 engaged therewith to move in the slide groove 24. Since two spiral grooves 261 in opposite directions and connected to each other are opened on the surface of the rotating rod 26, the slide plate 241 can move along a spiral groove 261 when the rotating rod 26 rotates. The spiral groove 261 is pushed to the end point and enters the spiral groove 261 in the other direction through the interconnected design, so that the rotating rod 26 can move back and forth in the slide groove 24, so that the slide plate 241 drives the air jet 242 on the surface to move along the axis direction of the autoclave curing tank, thereby improving the temperature consistency in the axis direction of the autoclave curing tank, so that the practicality of the utility model is further improved; and the setting of the air bag 25 can make the slide plate 241 slide in the slide groove 24. The gas in the slide groove 24 is always located in the air bag 25 in the slide groove 24, thereby preventing the steam in the slide groove 24 from leaking out, ensuring that the steam can The gas is discharged through the air jet 242 of the slide plate 241, which is beneficial to control the temperature distribution in the autoclave curing tank; and by setting the runner 271 and the air holes 273 on the surface of the runner 271; the gas in the slide 24 can enter the cavity 272 on the surface of the runner 271 through the air jet 242, so that the steam entering the cavity 272 can be ejected through the air holes 273. Since the air holes 273 are arranged obliquely, the gas ejected from the air holes 273 produces an oblique driving force on the runner 271, thereby driving the runner 271 to rotate. Since the runner 271 is made of PTFE material, the friction between the runner 271 and the groove wall of the groove 27 is small. The rotating wheel 271 can rotate quickly and effectively. During the rotation of the rotating wheel 271, the rotating wheel 271 sprays steam to the surrounding of the autoclave curing tank through the air holes 273, so that the steam is sprayed obliquely to the center of the autoclave curing tank, that is, the area below the autoclave curing tank and away from the slide plate 241, so that the steam can be sprayed to various areas inside the autoclave curing tank, so that the temperatures of the two areas of the autoclave curing tank can be effectively mixed, thereby improving the temperature consistency of various areas inside the autoclave curing tank, so that various parts of the calcium silicate board in the autoclave curing tank can be effectively steam-cured, so that the curing effect of the calcium silicate board is improved;

[0033] In the process of steam moving between the installation groove 2 and the autoclave curing tank, condensed water will continuously accumulate in the installation groove 2. If the condensed water accumulates and overflows the blades 21, it will not only block the normal rotation of the blades 21, but also affect the normal flow of steam between the installation groove 2 and the autoclave curing tank. In this regard, the utility model sets a water storage tank 16 so that the condensed water in the installation groove 2 can flow into the water storage tank 16 through the one-way valve 161. Since the drain port 17 is equipped with an electromagnetic valve 171, and the electromagnetic valve 171 is in a closed state, the condensed water will accumulate in the installation groove 2. The closed electromagnetic valve 171 is to prevent the steam in the autoclave curing tank from flowing out and causing heat loss. When the steam curing is completed, the electromagnetic valve 171 is controlled to open to discharge the condensed water in the water storage tank 16, thereby avoiding the accumulation of condensed water in the installation groove 2. The blades 21 in the installation groove 2 are guaranteed to rotate normally to improve the rapid and stable flow of steam between the installation groove 2 and the autoclave curing tank. The practical application effect of the utility model is further improved.

[0034] The utility model arranges the blades 21 so that the blades 21 can discharge the gas in the installation groove 2 and the air intake port 15, so that the air intake port 15 can suck the steam located in the upper area of ​​the autoclave curing tank and transport it to the installation groove 2, and then discharge it through the slide plate 241, so that the high-temperature steam can circulate in the autoclave curing tank, ensure the consistency of the temperature of the upper and lower areas in the autoclave curing tank, avoid uneven temperature distribution in the upper and lower areas of the autoclave curing tank, and enable the lower area of ​​the autoclave curing tank to effectively steam-cure the calcium silicate board, thereby improving the curing effect of the calcium silicate board; the hardness and strength of the calcium silicate board located in the lower area of ​​the autoclave curing tank can be effectively improved; thereby improving the practical application effect of the utility model.
