Description

Technical Field

[0001] The invention relates to the technical field of building material production, in particular to an autoclave device for environmentally friendly new building materials. Background Art

[0002] Autoclave, also known as steam curing autoclave or pressure autoclave, is a large pressure vessel with huge volume and heavy weight. Autoclave has a wide range of uses and is widely used in the autoclave curing of building materials such as aerated concrete blocks, concrete pipe piles, lime sand bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, and high-strength gypsum. Its working principle is to put the building materials into the autoclave body, and then heat the water in the autoclave through the heating system to produce a high temperature and high pressure steam environment. Under such conditions, the chemical reaction inside the building materials is accelerated, thereby improving the performance of the building materials, such as improving strength and durability.

[0003] However, during the production process of concrete blocks, the cut concrete blocks need to be sent to an autoclave for steam curing and drying, which has the following problems:

[0004] First, when taking concrete blocks out of the autoclave, workers need to enter the autoclave to assist in taking them out. However, the residual heat in the autoclave can easily affect the workers' breathing and health.

[0005] Second, in order to enhance the sealing performance of the autoclave, a seal is configured between most autoclaves and the autoclave door. However, as the autoclave door is frequently opened, the seal will be worn after long-term use, resulting in the seal and the autoclave door no longer fitting tightly, which results in an unsatisfactory sealing effect of the autoclave.

[0006] Third, when the autoclave door is opened, most of the seals installed on the autoclave door will be exposed outside the autoclave door, which makes the seals exposed to the external environment and easily damaged by external factors, affecting their sealing performance. In addition, the seals exposed to the outside may be contaminated with dust, impurities, oil and other pollutants. These pollutants may be brought into the autoclave when the autoclave door is closed for work, affecting the purity and quality of the bricks in the autoclave. In view of this, we propose an environmentally friendly autoclave device for new building materials. Summary of the invention

[0007] The purpose of the present invention is to provide an autoclave device for environmentally friendly new building materials to solve the problems raised in the above background technology.

[0009] When the kettle cover rotates to seal the front end opening of the kettle body, the synchronous moving mechanism generates a compressed rebound force and is confined in the inner cavity of the kettle body. At the same time, the sealing mechanism is driven to elastically abut against the tight fitting mechanism.

[0010] When the kettle cover rotates away from the front end opening of the kettle body, the synchronous moving mechanism drives the sealing mechanism to extend out of the inner cavity of the kettle body and squeezes and limits the tight fitting mechanism to be exposed outside the kettle cover. The tight fitting mechanism includes a secondary O-ring and a second return spring.

[0011] As a further improvement of the present technical solution, the synchronous movement mechanism includes a storage plate slidably connected to the inner wall of the kettle body, the inner wall of the kettle body is provided with two slide grooves, a plurality of pulleys are fixedly connected to the bottom of the storage plate, and the pulleys are respectively located in adjacent slide grooves.

[0012] As a further improvement of the technical solution, the sealing mechanism includes a main O-ring fixedly connected to the storage plate near the opening of the kettle body, and the outer diameter of the main O-ring is matched with the inner diameter of the opening of the kettle body.

[0013] As a further improvement of the technical solution, the kettle body includes a secondary O-ring slidably connected to the inner wall of the kettle cover, and the size of the secondary O-ring is adapted to the size of the main O-ring.

[0014] As a further improvement of the technical solution, a groove is provided on the inner wall of the kettle cover, and a plurality of No. 2 return springs are fixedly connected in the groove, and the side of the No. 2 return spring away from the groove is fixedly connected to one side of the secondary O-ring.

[0015] As a further improvement of the present technical solution, a plurality of limit rods are fixedly connected to the side of the main O-ring close to the storage plate, a plurality of positioning grooves are opened on the inner wall of the kettle body, sliders are slidably connected in the positioning grooves, and the side of the slider away from the positioning groove is fixedly connected to one side of the adjacent limit rod.

[0016] As a further improvement of the technical solution, a ventilation groove is provided inside the storage plate, and the ventilation groove is connected to the main O-ring;

[0017] The inner wall of the main O-shaped sealing ring is provided with a cavity for the gas in the ventilation groove to enter the interior of the main O-shaped sealing ring.

[0018] As a further improvement of the technical solution, a plurality of connecting rods are rotatably connected inside the ventilation slot, and both sides of the connecting rods pass through the ventilation slot. One side of the connecting rod passes through the ventilation slot and is fixedly connected to the rotating shaft of an adjacent pulley. One side of the plurality of connecting rods located inside the ventilation slot is fixedly connected to two fan blades.

[0019] As a further improvement of the technical solution, a through hole is provided on one side of the limit rod away from the slider;

[0020] An air inlet groove is provided inside each of the plurality of limit rods for allowing the gas in the main O-ring to enter the limit rod.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the autoclave device for environmentally friendly new building materials, by starting the kettle cover, the No. 1 return spring drives the placement plate to move outside the kettle body under the reaction force. Workers can push the trolley stacking bricks onto the placement plate or take out the bricks on the placement plate from outside the kettle body. There is no need for workers to enter the kettle body, which ensures the safety of workers and avoids discomfort caused by workers staying for a long time inside the kettle body filled with high-temperature steam.

[0024] 2. In the autoclave device for the new environmentally friendly building materials, the worker pushes the main O-ring and starts the kettle cover in reverse to drive the kettle cover to close and push the storage plate into the kettle body. At this time, under the reaction force of the No. 1 return spring, the storage plate and the main O-ring are pushed to move, so that the main O-ring and the auxiliary O-ring fit tightly, better filling the possible tiny gap between the two, thereby providing a tighter and more reliable sealing effect.

[0025] 3. In the autoclave device for environmentally friendly new building materials, when the placement plate moves toward the outside of the kettle body, it drives the limit rod to move outward, and the limit rod on the side and the auxiliary O-ring are squeezed, so that the auxiliary O-ring can be squeezed into the inside of the kettle cover, so that when the kettle cover is opened, the auxiliary O-ring can be put into the inside of the kettle cover, effectively preventing the auxiliary O-ring from being exposed to the outside world and being damaged by the outside world or contaminated by pollutants such as dust, impurities, and oil, thereby extending the service life of the auxiliary O-ring.

[0041] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 10As shown, this embodiment provides an autoclave device for environmentally friendly new building materials, including a kettle body 100, a kettle cover 110 is rotatably connected to the front opening of the kettle body 100, a driving motor is fixedly installed on one side of the kettle body 100, and the driving motor is started to drive the kettle body 100 to rotate to open and close the kettle cover 110. The opening direction of the kettle cover 110 is shown by arrow b. A synchronous moving mechanism 200 is slidably provided inside the kettle body 100, and a sealing mechanism 300 is fixedly connected to the end of the synchronous moving mechanism 200 close to the kettle cover 110, and a close fitting mechanism 400 is provided at the surface of the kettle cover 110 close to the kettle body 100, wherein:

[0043] When the kettle cover 110 rotates to seal the front end opening of the kettle body 100, the synchronous moving mechanism 200 generates a compressive resilience and is confined in the inner cavity of the kettle body 100. At the same time, the sealing mechanism 300 is driven to elastically abut against the tight fitting mechanism 400, thereby improving the sealing effect inside the kettle body 100 and ensuring the stability of the high temperature and high pressure environment inside the kettle, which is conducive to improving product quality and production efficiency.

[0044] When the kettle cover 110 rotates and separates from the front end opening of the kettle body 100, the synchronous moving mechanism 200 drives the sealing mechanism 300 to extend out of the inner cavity of the kettle body 100, so that workers can take and put bricks without having to enter the kettle body 100, thereby avoiding discomfort caused by workers staying for a long time inside the kettle body 100 filled with high-temperature steam, and squeezing and limiting the tight fitting mechanism 400 from being exposed to the outside of the kettle cover 110. The tight fitting mechanism 400 includes a secondary O-ring 410 and a No. 2 return spring 420, which effectively avoids the tight fitting mechanism 400 from being directly exposed to the external environment, thereby increasing the service life of the tight fitting mechanism 400.

[0045] In the process of taking concrete blocks out of the autoclave, workers need to enter the autoclave to assist in taking and placing. However, the residual heat in the autoclave can easily affect the workers' breathing and health. Therefore, a synchronous moving mechanism 200 is provided. When the autoclave cover 110 is opened, the elastic force generated by the synchronous moving mechanism 200 drives the synchronous moving mechanism 200 to move outside the autoclave body 100. Workers can push the trolley stacking bricks onto the synchronous moving mechanism 200 or take out the bricks outside the autoclave body 100. There is no need for workers to enter the autoclave body 100, which ensures the safety of workers and prevents workers from staying in the autoclave body 100 filled with high-temperature steam for a long time and causing discomfort.

[0046] In order to enhance the sealing performance of the autoclave, a sealing member is disposed between most autoclaves and the autoclave door. However, as the autoclave door is frequently opened, the sealing member will be worn after long-term use, so that the sealing member and the autoclave door are no longer tightly fitted, thereby causing the sealing effect of the autoclave to be unsatisfactory. Therefore, a sealing mechanism 300 and a tight fitting mechanism 400 are provided. When the autoclave body 100 is closed, the synchronous moving mechanism 200 generates a compressed resilience, thereby driving the sealing mechanism 300 to closely abut against the tight fitting mechanism 400. The elastic force enables the sealing mechanism 300 to be adaptively adjusted according to the position and shape of the tight fitting mechanism 400, so as to better fill the possible tiny gaps, thereby providing a tighter and more reliable sealing effect.

[0047] When the autoclave door is opened, most of the seals installed on the autoclave door will be exposed outside the autoclave door, which makes the seals exposed to the external environment and easily damaged by external factors, affecting their sealing performance. In addition, the seals exposed to the outside may be contaminated with dust, impurities, oil stains and other pollutants. These pollutants may be brought into the autoclave when the autoclave door is closed for operation, affecting the purity and quality of the bricks in the autoclave. Therefore, a synchronous moving mechanism 200 is provided. When the autoclave cover 110 is opened, the synchronous moving mechanism 200 can squeeze the tight fitting mechanism 400 and squeeze the tight fitting mechanism 400 into the interior of the autoclave cover 110 to avoid direct exposure of the tight fitting mechanism 400 to the external environment, thereby reducing the contamination of the tight fitting mechanism 400 by dust, impurities, oil stains and other pollutants, and extending the service life of the tight fitting mechanism 400.

[0048] Considering the need to put bricks into the kettle body 100, Figure 2-Figure 5 As shown, the synchronous moving mechanism 200 includes a storage plate 210 slidably connected to the inner wall of the kettle body 100. The moving direction of the storage plate 210 is shown by arrow a. A slide rail is provided on the upper surface of the storage plate 210. When it is necessary to push the trolley with bricks to the top of the storage plate 210, the docking plate is aligned with the top of the storage plate 210, and the trolley above the docking plate is pushed to the top of the storage plate 210. The docking plate is a prior art and will not be described in detail here. Two slide grooves 230 are provided on the inner wall of the kettle body 100, and a plurality of pulleys 240 are fixedly connected to the bottom of the storage plate 210, and the pulleys 240 are respectively located in the adjacent slide grooves 230. The slide grooves 230 are provided to provide guidance for the movement of the storage plate 210. The pulleys 240 are provided to reduce the friction between the storage plate 210 and the bottom of the kettle body 100, so that the storage plate 210 can move better inside the kettle body 100.

[0049] Considering the need to improve the sealing performance of the kettle body 100, as Figure 3 and Figure 7As shown, the sealing mechanism 300 includes a main O-ring 310 fixedly connected to the placement plate 210 near the opening of the kettle body 100. The main O-ring 310 can effectively reduce the leakage of high-temperature gas inside the kettle body 100, improve the utilization efficiency of high-temperature gas, and reduce energy consumption. The outer diameter of the main O-ring 310 is compatible with the inner diameter of the opening of the kettle body 100, which can ensure that the main O-ring 310 fits tightly with the opening of the kettle body 100, minimize the leakage of high-temperature gas, and improve the sealing reliability of the kettle body 100.

[0050] In order to further improve the sealing effect of the kettle body 100, as Figure 5 and Figure 7 As shown, the kettle body 100 includes a secondary O-ring 410 slidably connected to the inner wall of the kettle cover 110, and the size of the secondary O-ring 410 is adapted to the size of the main O-ring 310. The secondary O-ring 410 is provided to form a double sealing defense line, which greatly improves the sealing reliability of the kettle body 100. Even if one of the seals is slightly damaged or the sealing performance is reduced, the other seal can still function, effectively preventing leakage of high-temperature gas, and improving the sealing effect of the device.

[0051] Considering the need to drive the secondary O-ring 410 to move to the interior of the kettle cover 110, as shown in FIG. Figure 7 As shown, a groove is provided on the inner wall of the kettle cover 110, and a plurality of No. 2 return springs 420 are fixedly connected in the groove, and the side of the No. 2 return spring 420 away from the groove is fixedly connected to one side of the secondary O-ring 410. When the secondary O-ring 410 is squeezed, the No. 2 return spring 420 is compressed and deformed, and the secondary O-ring 410 can be squeezed into the kettle cover 110. When the secondary O-ring 410 is not squeezed, the secondary O-ring 410 is driven to reset and move under the force of the No. 2 return spring 420 to restore the deformation.

[0052] Considering that it is necessary to squeeze the auxiliary O-ring 410 when the kettle cover 110 is opened, the auxiliary O-ring 410 is received inside the kettle cover 110. Figure 3-Figure 4As shown, a side of the main O-ring 310 close to the placement plate 210 is fixedly connected with a plurality of limiting rods 320. When the placement plate 210 moves toward the outside of the kettle body 100, the limiting rod 320 is driven to move outward, and the side limiting rod 320 is squeezed with the secondary O-ring 410, so that the secondary O-ring 410 can be squeezed into the inside of the kettle cover 110, so that when the kettle cover 110 is opened, the secondary O-ring 410 can be retracted into the inside of the kettle cover 110, effectively avoiding the secondary O-ring 410 from being exposed to the outside and being damaged by the outside, thereby affecting the sealing performance of the secondary O-ring 410. A plurality of positioning grooves are provided on the inner wall of the kettle body 100, and sliders 321 are slidably connected in the positioning grooves, and the side of the slider 321 away from the positioning groove is fixedly connected with one side of the adjacent limiting rod 320. The positioning groove and the slider 321 are provided to provide guidance and stability for the movement of the limiting rod 320.

[0053] In order to allow the gas inside the storage plate 210 to enter the main O-ring 310, Figure 8-Figure 9 As shown, a ventilation slot 270 is provided inside the storage plate 210, and the ventilation slot 270 is connected to the main O-ring 310, and an air inlet is provided on one side of the storage plate 210 to facilitate the air to enter the ventilation slot 270, and then enter the main O-ring 310;

[0054] The inner wall of the main O-ring 310 is provided with a cavity for the gas in the ventilation groove 270 to enter the main O-ring 310 . The gas in the ventilation groove 270 can flow into the cavity provided inside the main O-ring 310 .

[0055] Considering the need to promote the flow of gas inside the ventilation slot 270, Figure 6-Figure 9 As shown, a plurality of connecting rods 250 are rotatably connected inside the ventilation slot 270, and both sides of the connecting rods 250 are arranged to penetrate the ventilation slot 270. One side of the connecting rod 250 penetrates the ventilation slot 270 and is fixedly connected to the rotating shaft of the adjacent pulley 240. One side of the plurality of connecting rods 250 located inside the ventilation slot 270 is fixedly connected to two fan blades 260. When the storage plate 210 moves, the pulley 240 is driven to slide inside the kettle body 100. When the pulley 240 rolls, the connecting rod 250 is driven to rotate, thereby driving the fan blades 260 to rotate, so that the gas inside the ventilation slot 270 can circulate.

[0056] In order to allow the gas inside the ventilation slot 270 to flow into the limiting rod 320, Figure 8-Figure 10As shown, a through hole is provided on one side of the limiting rod 320 away from the slider 321. The limiting rod 320 is provided with a through hole, so that the gas inside the limiting rod 320 is blown to the surface of the brick placed on the placing plate 210 through the through hole, which can not only accelerate the volatilization of the heat on the surface of the brick, and facilitate the cooling of the brick, but also the gas blowing can make the temperature of the brick drop more evenly, effectively avoiding the risk of brick cracking or deformation caused by the internal stress generated by the large temperature difference when the heated brick is removed from the inside of the kettle 100, thereby ensuring the appearance integrity and structural strength of the brick;

[0057] like Figure 5 As shown, the air flow direction flows from the arrow c to the arrow d, and finally flows to the moving direction of the arrow e. The interiors of the plurality of limit rods 320 are provided with air inlet grooves for the gas in the main O-ring 310 to enter the interior of the limit rod 320. The gas in the ventilation groove 270 enters the interior of the main O-ring 310. The gas in the main O-ring 310 can enter the interior of the limit rod 320 through the air inlet grooves provided inside the limit rod 320.

[0058] Considering the need to drive the storage plate 210 to move out of the kettle body 100, Figure 2-Figure 4 As shown, a plurality of No. 1 return springs 220 are fixedly connected to one side of the storage plate 210 away from the main O-ring 310. , and the side of the No. 1 return spring 220 away from the placement plate 210 is fixedly connected to the inner wall of the kettle body 100. When the placement plate 210 is located inside the kettle body 100, the No. 1 return spring 220 is in a compressed state. When the kettle cover 110 is opened, the placement plate 210 is driven to move out from the inside of the kettle body 100 under the reaction force of the No. 1 return spring 220. With the help of external tools, it is convenient for workers to push the trolley with bricks to the top of the placement plate 210. Bricks can be placed or taken out without the need for workers to enter the inside of the kettle body 100. When the kettle cover 110 is closed, the placement plate 210 is located inside the kettle body 100. Under the reaction force of the No. 1 return spring 220, the placement plate 210 is pushed to move, thereby pushing the main O-ring 310 to move, so that the main O-ring 310 and the auxiliary O-ring 410 are tightly fitted, thereby improving the sealing performance of the device.

[0059] Working principle: When it is necessary to put the bricks to be processed into the kettle body 100, the kettle cover 110 is started to drive the kettle cover 110 to rotate, so as to open the kettle cover 110. When the placement plate 210 is located inside the kettle body 100, the slide groove 230 is in a compressed state. When the kettle cover 110 is opened, the placement plate 210 is driven to move out from the kettle body 100 under the reaction force of the No. 1 return spring 220. With the help of external tools, it is convenient for workers to push the trolley for stacking bricks onto the top of the placement plate 210 without the need for workers to enter the kettle body 100. Bricks can be placed or taken out, and when the placement plate 210 moves toward the outside of the kettle body 100, the limiting rod 320 is driven to move outward, and the limiting rod 320 on the side is squeezed with the auxiliary O-ring 410, so that the auxiliary O-ring 410 can be squeezed into the inside of the kettle cover 110, so that when the kettle cover 110 is opened, the auxiliary O-ring 410 can be put into the inside of the kettle cover 110, effectively preventing the auxiliary O-ring 410 from being exposed to the outside and being damaged by the outside, thereby affecting the sealing performance of the auxiliary O-ring 410;

[0060] After the placement is completed, the worker pushes the main O-ring 310 to drive the limit rod 320 and the placement plate 210 to move into the kettle body 100. When the main O-ring 310 is within the rotation range of the kettle cover 110, the kettle cover 110 is then started to drive the kettle cover 110 to close. The kettle cover 110 can push the main O-ring 310 to move into the kettle body 100. When the kettle cover 110 is closed, the placement plate 210 is located inside the kettle body 100 at this time. Under the reaction force of the No. 1 return spring 220, the placement plate 210 is pushed to move, thereby pushing the main O-ring 310 to move, so that the main O-ring 310 and the auxiliary O-ring 410 are tightly fitted, thereby improving the sealing performance of the device.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
