Description

Technical Field

[0001] The present invention relates to the technical field of material mixing devices, and particularly to a raw material mixing self - quantitative pouring device for aerated bricks. Background Art

[0002] Aerated bricks are a kind of lightweight building materials, mainly made of raw materials such as cement, lime, sand and fibers. They get their name because lightweight aggregates or foaming agents are added to the materials. Their main characteristics are low density and light weight. The pouring of aerated bricks mainly involves adding granular raw materials such as lime, sand, aluminum powder, foaming agent, etc. into a trough - shaped mold after being mixed with water, and then sending them into a reaction kettle for foaming and solidification.

[0003] In the prior art, before pouring, in order for aluminum powder and water to fully contact and react, stirring is required to make the materials evenly mixed. However, during the stirring process, air bubbles will disperse and burst. Some devices will first fully mix all raw materials except water, and then add water for stirring, so as to reduce the stirring time. However, this method still has some time in mechanical stirring and cannot well offset the mechanical shear force during stirring, which will cause some air bubbles formed during the pre - pouring stirring to burst, thus reducing the quality of aerated bricks. Summary of the Invention

The air outlet of the second air guide groove is communicated with the air outlet hole. A connecting ring is rotatably arranged at the bottom end of the elevating cover plate. A stirring plate is fixedly connected to the bottom end of the connecting ring.

[0011] As a further description of the above technical solution: The discharging mechanism includes an air bag two. A fixed stop block is fixedly connected to the inner wall of the fixed shell, and a notch is opened on the fixed stop block. A convex block is fixedly connected to the inner wall of the elevating block above the fixed stop block. The shape of the convex block is adapted to the notch. An inserting block is slidably arranged up and down on the lower surface of the elevating cover plate. An exhaust groove is opened at the bottom end of the inserting block. A second spring is fixedly connected between one end of the inserting block and the elevating cover plate. An air bag three is abutted against the upper side of the inserting block.

[0014] As a further description of the above technical solution: A plurality of the stirring plates are arranged at equal intervals in a ring shape.

[0015] As a further description of the above technical solution: The air bag three is more difficult to expand than the air bag two.

[0016] The present invention provides an automatic metering pouring device for mixing raw materials of aerated bricks through improvement. Compared with the prior art, it has the following improvements and advantages:

[0017] First: The air blowing pump introduces the gas outside through the air duct into the inner cavity on the upper side of the fixed shell. After that, the lifting block will be pushed downward by the gas, and the lifting block will drive the lifting cover plate to slide downward together, thereby increasing the pressure in the inner cavity of the inner barrel. During stirring, the aluminum powder reacts with water to generate bubbles. The pressure outside the bubbles is higher than the pressure inside the bubbles, making the bubbles less likely to be broken by the stirring component, better preserving the number of initial bubbles before pouring, reducing the escape of hydrogen generated before pouring, and improving the quality of the subsequent aerated bricks.

[0018] Second: On the basis of being able to increase the pressure, the air flow can be used as a power source to drive the stirring plate to stir and mix the raw materials. At the same time, because there is quicklime in the raw materials, after adding water, the raw materials will gradually release heat, and the released heat will also cause the bubbles to burst. When the gas passes through the cavity, it will bring the heat at the lower end of the lifting cover plate to the outside to dissipate heat from the lifting cover plate. The lifting cover plate is in contact with the gas in the inner cavity of the inner barrel, and thus can also reduce the temperature in the inner cavity of the inner barrel. Therefore, the pumping of the gas further prevents the bubbles from bursting.

[0019] Third: When it is necessary to discharge the material after stirring, a part of the pumped gas can be discharged from the bottom end of the insert block into the inner cavity of the inner barrel. Due to the sealing of the second airbag at this time, this part of the gas can discharge the liquid raw material in the inner barrel from the bottom end of the inner barrel. Discharging the material through the pumped gas can not only prevent the raw materials from being too viscous and causing slow discharging, but also make the raw materials discharged more thoroughly.

[0020] In summary, through the gas pumped by the air blowing pump, when stirring, the flow of the gas can increase the pressure in the inner cavity of the inner barrel, making the bubbles less likely to be broken by the stirring component. And when the pumped gas flows, it dissipates heat from the lifting cover plate and reduces the temperature in the inner cavity of the inner barrel, further preventing the bubbles from bursting. When it is necessary to discharge the material, only the pumping intensity of the air blowing pump needs to be increased. A part of the pumped gas can be discharged from the bottom end of the insert block into the inner cavity of the inner barrel. Discharging the material through the pumped gas can not only prevent the raw materials from being too viscous and causing slow discharging, but also make the raw materials discharged more thoroughly.

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] Please refer to Figure 1 - Figure 9 , the embodiment of the present invention provides a technical solution: a raw material mixing and self-dosing pouring device for aerated bricks, including a fixed seat 1 and an air blowing pump 2 located on one side of the fixed seat 1. An inner barrel 7 is fixedly connected to the inner cavity of the fixed seat 1. A connecting rod 3 is fixedly connected to the upper inner wall of the fixed seat 1, and a fixed shell 51 is fixedly connected to the connecting rod 3. A gas guide pipe 4 is communicated between the upper inner cavity of the fixed shell 51 and the air blowing pump 2. An automatic valve 6 is arranged at the lower end of the inner barrel 7. The device further includes:

[0034] A pressurizing mechanism 5 for pressurizing during stirring to reduce the rupture of formed bubbles. The pressurizing mechanism 5 is arranged on the fixed shell 51;

[0035] A stirring mechanism 8, which uses gas as the power source for stirring, is arranged on the pressurizing mechanism 5;

[0036] And a discharging mechanism 9, which is used to thoroughly discharge the gas, is arranged inside the pressurizing mechanism 5.

[0037] Specifically, for the gas pumped in by the air blowing pump 2, when stirring, the flow of the gas can increase the pressure inside the inner cavity of the inner barrel 7, making it more difficult for the bubbles to be broken by the stirring components. And when the pumped-in gas flows, it dissipates heat from the lifting cover plate 52, reducing the temperature inside the inner cavity of the inner barrel 7, further preventing the bubbles from bursting. When discharging is required, only the pumping intensity of the air blowing pump 2 needs to be increased. A part of the pumped-in gas can be discharged into the inner cavity of the inner barrel 7 from the bottom end of the inserting block 95. Discharging with the pumped-in gas can not only prevent the raw materials from being sticky and causing slow discharging, but also make the raw materials be discharged more thoroughly.

[0038] In another embodiment provided by the present invention, the pressurizing mechanism 5 includes a fixed shell 51, and the fixed shell 51 is located at the center of the inner cavity of the fixed seat 1. A lifting block 53 is slidably arranged up and down inside the fixed shell 51. A first spring 54 is fixedly connected between the top end of the lifting block 53 and the fixed shell 51. An outer wall of the lifting block 53 is fixedly connected with a lifting cover plate 52, and the lifting cover plate 52 is slidably arranged up and down on the fixed shell 51. An air bag two 91 is arranged on the lower outer wall of the lifting cover plate 52. The inner cavity of the air bag two 91 is communicated with the upper inner cavity of the lifting block 53. The bottom inner cavity of the fixed shell 51 is communicated with the outside of the fixed shell 51.

[0039] In another embodiment provided by the present invention, the stirring mechanism 8 includes an air guiding groove one 83 opened in the lifting block 53, an air guiding groove two 84 is opened in the fixed shell 51, and the air inlet of the air guiding groove two 84 is located below the air outlet of the air guiding groove one 83. A cavity 811 is opened in the lifting cover plate 52. An exhaust port 82 communicated with the cavity 811 is opened at the upper end of the lifting cover plate 52. A vortex fan 85 is rotatably arranged in the cavity 811. An air outlet hole 86 is opened on the lower side wall of the cavity 811. The air outlet of the air guiding groove two 84 is communicated with the air outlet hole 86. A connecting ring 87 is rotatably arranged at the bottom end of the lifting cover plate 52, and a stirring plate 81 is fixedly connected to the bottom end of the connecting ring 87.

[0040] The bottom end of the fixed shell 51 is located above the liquid in the inner barrel 7.

[0041] A lifting frame 88 is slidably arranged up and down inside the connecting ring 87. Connecting plates 810 are fixedly connected to both the inner and outer sides of the lifting frame 88, and an air bag one 89 is abutted against the upper side of the connecting plates 810. The air bag one 89 is arranged in the lifting cover plate 52.

[0042] A plurality of stirring plates 81 are arranged in an annular and equally spaced manner.

[0043] Specifically, for the gas pumped in by the air blowing pump 2, when stirring, the flow of the gas can increase the pressure in the inner cavity of the inner barrel 7, making the bubbles less likely to be broken by the stirring component. When the pumped-in gas flows, it dissipates heat from the lifting cover plate 52 and reduces the temperature in the inner cavity of the inner barrel 7, further preventing the bubbles from bursting.

[0044] In another embodiment provided by the present invention, the discharging mechanism 9 includes an airbag two 91. A fixed stop block 92 is fixedly connected to the inner wall of the fixed shell 51, and a notch 93 is formed in the fixed stop block 92. A convex block 94 is fixedly connected to the inner wall of the lifting block 53 above the fixed stop block 92. The convex block 94 is adapted to the shape of the notch 93. An insertion block 95 is slidably arranged on the lower surface of the lifting cover plate 52 up and down. An exhaust groove is formed at the bottom end of the insertion block 95. A spring two 98 is fixedly connected between the lower surface of one end of the insertion block 95 and the lifting cover plate 52. An airbag three 97 abuts against the upper side of the insertion block 95. The inner cavity of the airbag three 97 is connected to the inner cavity of the airbag two 91 through a hose 96.

[0045] The airbag three 97 is more difficult to expand than the airbag two 91.

[0046] Specifically, when discharging is required, only the air extraction intensity of the air blowing pump 2 needs to be increased. Part of the pumped-in gas can be discharged into the inner cavity of the inner barrel 7 from the bottom end of the insertion block 95. Discharging with the pumped-in gas can not only prevent the raw material from being sticky and causing slow discharging, but also make the raw material discharge more thoroughly.

[0047] Working principle: When using this device, first close the automatic valve 6, then add the raw material and water into the inner barrel 7 successively. At this time, the lifting cover plate 52 is located above the inner barrel 7. Then start the air blowing pump 2. The air blowing pump 2 introduces the gas outside through the air guide pipe 4 into the upper inner cavity of the fixed shell 51. Then the lifting block 53 will be pushed downward by the gas. The lifting block 53 will drive the lifting cover plate 52 to slide downward together, thereby increasing the pressure in the inner cavity of the inner barrel 7. When stirring, aluminum powder reacts with water to generate bubbles. The pressure outside the bubbles is higher than the pressure inside the bubbles, making the bubbles less likely to be broken by the stirring component, better preserving the number of initial bubbles before pouring, reducing the escape of hydrogen generated before pouring, and improving the quality of the subsequent aerated bricks.

[0048] When the lifting block 53 continues to move downward and the bottom end of the first air guide groove 83 coincides with the second air guide groove 84, the gas in the upper inner cavity of the fixed shell 51 will enter the cavity 811 through the first air guide groove 83 and the second air guide groove 84. After that, the gas will be exported from the air outlet hole 86 and then discharged to the outside from the exhaust port 82. During the process of the gas flowing from bottom to top, the air flow will drive the vortex fan 85 to rotate, so that the vortex fan 85 can drive the lower connecting ring 87 and the stirring plate 81 to rotate. Thus, on the basis of being able to increase the pressure, the air flow can be used as a power source to drive the stirring plate 81 to stir and mix the raw materials. At the same time, since there is quicklime in the raw materials, after adding water, the raw materials will gradually release heat, and the released heat will also promote the rupture of the bubbles. When the gas passes through the cavity 811, it will take the heat at the lower end of the lifting cover plate 52 to the outside to dissipate the heat of the lifting cover plate 52. The lifting cover plate 52 is in contact with the gas in the inner cavity of the inner barrel 7, and thus can also reduce the temperature of the inner cavity of the inner barrel 7. Therefore, the pumping of the gas further prevents the rupture of the bubbles;

[0049] When the lifting cover plate 52 starts to move downward, the convex block 94 is located above the notch 93. After that, when the second airbag 91 is located in the inner cavity of the inner barrel 7, the convex block 94 is inserted into the notch 93, so that the gas above and below the fixed stop block 92 is no longer connected. At this time, when the lifting block 53 continues to move downward, the gas in the lifting block 53 above the fixed stop block 92 will be pressed into the second airbag 91, so that the second airbag 91 is closely attached to the upper inner wall of the inner barrel 7, which can improve the airtightness of the subsequent inner cavity of the inner barrel 7 and prevent the pressure in the inner barrel 7 from decreasing;

[0050] When it is necessary to discharge the material after stirring, open the automatic valve 6. After that, just increase the pumping intensity of the air blowing pump 2 so that the lifting block 53 can continue to move downward to the bottom side. At this time, more gas in the lifting block 53 above the fixed stop block 92 will be pressed into the second airbag 91. However, at this time, the second airbag 91 abuts against the inner wall of the inner barrel 7 and cannot expand anymore. The excess gas will enter the inner cavity of the more difficult-to-expand third airbag 97. After that, the third airbag 97 expands, causing the insertion block 95 to move downward, so that the exhaust groove in the insertion block 95 is connected to the second air guide groove 84. A part of the pumped gas can be discharged from the bottom end of the insertion block 95 into the inner cavity of the inner barrel 7. Due to the sealing of the second airbag 91 at this time, this part of the gas can discharge the liquid raw material in the inner barrel 7 from the bottom end of the inner barrel 7. Discharging the material by pumping in gas can not only prevent the raw materials from being too viscous and causing slow discharging, but also make the raw materials discharged more thoroughly;

[0051] And during discharging, the stirring plate 81 can still continue to stir to prevent the settlement of aluminum powder during discharging;

[0052] The first airbag 89 is provided to make the lower end of the lifting frame 88 abut more closely against the lifting cover plate 52 and enhance the sealing performance;

[0053] After the discharging is completed, the air blowing pump 2 is turned off, and the lifting block 53 will bounce upward due to the contraction of the first spring 54, which can shake off a small amount of raw materials adhered to the stirring plate 81, so that the discharging can be more thorough.

[0054] 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 descriptions in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
