DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0021] Embodiment 1, as Figure 1 , 2 As shown in Figures 3, 4 and 5, a one-time sintering insulation block preparation mechanism comprises a kiln 1 and a conveying route passing through the kiln 1 in the front-to-back direction. The central roller conveyor line is used for heating, sintering and conveying the insulation blocks k. The central roller conveyor line comprises a left branch line and a right branch line. In this embodiment, the insulation blocks are supported and conveyed in the kiln 1 by two rows of left and right branches. The kiln 1 is also a sintering furnace, which can be a fuel-burning sintering heating kiln. The sintering and heating can be better performed by separate supports on the left and right. Here, of course, the sintering time in the kiln 1 is generally at least 10 hours, and the heating temperature is generally more than one thousand degrees. Due to the long time, the speed of the central roller conveyor line is very slow, and it can be adaptively adjusted according to the front-to-back length of the kiln 1. The conveying direction of the kiln is front and back, and the central roller conveyor line is located in the center of the kiln, that is, the insulation blocks will be sintered and heated in the middle suspended position. Since the sintering effect of this example is better, the sintering time can be less than 10 hours and the efficiency is correspondingly improved.

[0022] Specifically, the left branch line includes a row of left conveying rollers g1 that are arranged on the left side wall of the kiln 1 and are spaced apart from each other, and the right branch line includes a row of right conveying rollers g2 that are arranged on the right side wall of the kiln 1 and are spaced apart from each other. The left conveying rollers g1 and the right conveying rollers g2 are spaced apart from each other and form a sintering heat circulation zone g0 at the intervals. The left and right side walls of the kiln 1 can be installed with bearings embedded therein for the left and right conveying rollers g1 and g2 to be supported and rotated conveniently. The bearings can be high-temperature bearings and can be used at high temperatures. The left conveying rollers g1 and the right conveying rollers g2 are spaced apart from each other to form a sintering heat circulation zone g0 so that the hot air can flow up and down, and the sintering heating of the insulation blocks is more uniform and transparent. When the insulation blocks are placed, the brick holes of the insulation blocks are in the up and down directions, which makes it more convenient for the heat flow to flow up and down for sintering, and the effect is better. Furthermore, the top of the kiln 1 is provided with a top fuel nozzle d1, and the bottom of the kiln 1 is provided with a bottom fuel nozzle d2. The top fuel nozzle d1 and the bottom fuel nozzle d2 can be installed on the top and bottom of the kiln according to the existing assembly method, so that the upper and lower heating and sintering uniformity will be better. Furthermore, between the left branch line and the right branch line, there is also a heat-insulating block stacking bearing moving frame b that can be placed on the right end of the left conveying roller g1 and the left end of the right conveying roller g2. Of course, there are many right ends of the left conveying roller g1 and the right conveying roller g2, and they are arranged one by one on the left and right. The heat-insulating block stacking bearing moving frame b can be supported by multiple right ends of the left conveying roller g1 and the left end of the right conveying roller g2 at the same time, and because of the existence of the sintering heat flow interval g0, the upper and lower sintering heat flows can better pass through the heat-insulating blocks. More preferably, the heat-insulating block stacking bearing moving frame b can be ventilated up and down, that is, it can be ventilated up and down, so that the sintering heat can be better carried out.

[0023] Preferably, the left conveying roller g1 is connected to a left pre-limiting plate 21, and the right conveying roller g2 is connected to a right pre-limiting plate 31. The portion of the left conveying roller g1 on the right side of the left pre-limiting plate 21 serves as a left-end bearing section 22, and the portion of the right conveying roller g2 on the left side of the right pre-limiting plate 31 serves as a right-end bearing section 32. The axial directions of the left and right conveying rollers g1 and g2 are both in the left and right directions. The left pre-limiting plate 21 is used to limit the insulation block stacking bearing moving frame b on the left side, and the right pre-limiting plate 31 is used to limit the insulation block stacking bearing moving frame b on the right side. The meaning of pre-limiting is that, firstly, the number of the left pre-limiting plates 21 and the right pre-limiting plates 31 is the same, and the front and rear positions correspond one to one to the left and right, that is, the left and right conveying rollers correspond one to one to the left and right, so the interval between the corresponding left pre-limiting plates 21 and the right pre-limiting plates 31 forms a The insulation block stacking bearing moving frame b is limited, but the spacing distance between the left pre-limiting plate 21 and the right pre-limiting plate 31 is greater than the left and right dimensions of the insulation block stacking bearing moving frame b. There are gaps between the left and right sides of the insulation block stacking bearing moving frame b and the left pre-limiting plate 21 and the right pre-limiting plate 31, respectively, that is, it can move left and right, but this pre-limiting is to facilitate the insulation block stacking bearing moving frame b to enter the furnace more smoothly, so that the insulation block stacking bearing moving frame b can be between the left pre-limiting plate 21 and the right pre-limiting plate 31, and then there is a more effective limiting effect. The left pre-limiting plate 21 can be fixed on the left conveying roller g1, and can be fixed in an existing adjustable and detachable manner, or in a welding or other fixing manner that is not easy to adjust. The right pre-limiting plate 31 is installed and connected on the right conveying roller g2 with reference to the left side.

[0024] The left end bearing section 22 and the right end bearing section 32 are used to support the insulation block stacking bearing moving frame b on the left and right sides respectively and to form the sintering heat flow zone g0 on the left and right sides. The insulation block stacking bearing moving frame b is located between the left pre-limiting plate 21 and the right pre-limiting plate 31. The reason for this setting is that the left-end bearing section 22 and the right-end bearing section 32 are used to support the insulation block stacking bearing moving frame b on the left and right sides respectively and form a sintering heat circulation interval g0 with left and right intervals. This setting is to support the insulation block stacking bearing moving frame b by two separate left-end bearing sections 22 and right-end bearing sections 32 on the left and right sides. The advantage of this is that a large space can be reserved at the bottom of the insulation block stacking bearing moving frame b for heating. In order to ventilate up and down, the insulation block stacking bearing moving frame b also has corresponding circulation holes at the bottom, which will greatly reduce the sintering effect caused by bottom obstruction, that is, a large space can be reserved on the lower side of the insulation block stacking bearing moving frame b for heating, so that the uniformity of upper and lower heating can be greatly improved, and the left and right length dimensions of the left and right bearing sections 22 and 32 can be set slightly smaller. For example, the left and right length dimensions of the left and right bearing sections 22 do not exceed one-fourth of the left and right length dimensions of the aluminum alloy workpiece, so that the sintering heat circulation interval g0 has a large enough area on the lower side of the moving frame. In addition, the arrangement density of the left conveying roller g1 and the right conveying roller g2 must be sufficiently guaranteed to ensure that a moving frame has at least two groups of left conveying rollers g1 and right conveying rollers g2 to support and convey it during sintering.

[0025] Further, the insulating block stacking bearing moving frame b is in the shape of a rectangular strip extending forward and backward, and the insulating block stacking bearing moving frame b is formed with at least one row of stacking limiting grids b1 with openings facing upwards, which are arranged and separated in front and back for the insulating blocks to be placed. The stacking limiting grids b1 are generally rectangular blocks, and if the blocks are special-shaped, the stacking limiting grids b1 are set to the corresponding special-shaped, and are matched as much as possible. The insulating blocks are placed in the stacking limiting grids b1 for storage, sintering and walking. The bottom of the stacking grids b1 is provided with bottom vents b2 connected to the stacking grids b1, so that the insulating block stacking bearing moving frame b can be ventilated up and down, and the heat flow can be well passed through the blocks for sintering up and down. Of course, the bottom vents b2 can be set with multiple small ones, or one large one, as long as the insulating blocks are not allowed to fall. The stacking limit grid b1 can be set in multiple rows on the left and right and in a rectangular array, which can be selected according to actual production requirements. The insulating block stacking bearing moving frame b can be made of high-temperature resistant metal and other materials. If the furnace is long enough, multiple insulating block stacking bearing moving frames b arranged front and back can be placed. By setting an existing switch monitoring system, the furnace door can be opened and closed in time. The furnace door is generally two, one inlet and one outlet. When the sintered insulating block stacking bearing moving frame b with insulating blocks is taken out through the open outlet door, the new insulating block stacking bearing moving frame b with insulating blocks to be sintered should be added accordingly, and then the door should be closed in time to reduce heat loss. The feature of the present application is that the insulating block stacking bearing moving frame b can produce the final material by sintering the insulating block blanks once, that is, the preparation can be completed by one-time sintering. Therefore, the insulation block material loaded on the insulation block stacking bearing moving frame b is the blank formed by the existing forming structure, and then sent to the kiln for sintering to obtain the final material. However, the blank is generally dried to reduce the moisture content and form an intermediate material. Therefore, the insulation block stacking bearing moving frame b is better to sinter the dried intermediate material, and the effect will be better.

[0026] Preferably, the left end of the left conveying roller g1 is located on the left outer side of the kiln 1 and is connected by the left chain t1, and the right end of the right conveying roller g2 is located on the right outer side of the kiln 1 and is connected by the right chain t2, wherein the left end of the left conveying roller g1 needs to be installed with a connecting sprocket, and the left chain t1 is wound on all the left sprockets. Of course, there is also a left driving sprocket, which is wound in the left chain t1, and the driving sprocket is connected to the driving motor, so that the rotation of the left conveying roller g1 can be controlled by controlling the driving motor, thereby driving the insulation block stacking carrying moving frame b to travel and heat in the furnace. The transmission structure on the right side can be implemented in the left way.

[0027] Preferably, the kiln 1 is provided with a left support pipe pile 41 extending from the bottom to the top, and the upper end of the left support pipe pile 41 is connected to the left inner rotating bearing body 411 for supporting and rotating the left conveying roller g1. The kiln 1 is also provided with a right support pipe pile 42 extending from the bottom to the top, and the upper end of the right support pipe pile 42 is connected to the right inner rotating bearing body 421 for supporting and rotating the right conveying roller g2. It should be noted that the structures in the furnace are all made of high temperature resistant materials. The left support pipe pile 41 and the right support pipe pile 42 are fixed at the bottom of the furnace and are upright. Since the left conveying roller g1 and the right conveying roller g2 are only supported by one side of the furnace wall when they are set, the stability is relatively poor, easy to roll over, unstable, and there will be safety hazards. Therefore, through the secondary support of the support pipe pile in the furnace, it can be more stable. At the same time, the left inner rotating bearing body 411 needs to be used in conjunction with the left conveying roller g1 to better support the left conveying roller g1 and operate smoothly. The same is true for the right side structure.

[0028] Furthermore, a plurality of auxiliary gas nozzles 40 spaced apart from each other are installed on the left supporting pipe pile 41 and the right supporting pipe pile 42. The kiln 1 of this embodiment is preferably combustion-type heated, and the auxiliary gas nozzles 40 are arranged to provide secondary heat supplementation in a specific area, while the gas pipeline can be arranged in the left supporting pipe pile 41 and the right supporting pipe pile 42, extending from the outside of the furnace into the furnace. In addition, the left supporting pipe pile 41 and the right supporting pipe pile 42 can also be connected to a blow pipe, which can blow air to the high-temperature area and evenly distribute the heat to other locations. There can be multiple gas nozzles and blow pipes for fine control.

[0029] Furthermore, the left pre-limiting plate 21 and the right pre-limiting plate 31 are both circular plates, and the periphery of the left pre-limiting plate 21 is provided with a left limiting annular plate 51 that can move left and right, and the left limiting annular plate 51 is installed and connected with a left rotating limiting body 511 for abutting and limiting the left side of the insulating block stacking bearing moving frame b, and the periphery of the right pre-limiting plate 31 is provided with a right limiting annular plate 52 that can move left and right, and the right limiting annular plate 52 is installed and connected with a right rotating limiting body 521 for abutting and limiting the right side of the insulating block stacking bearing moving frame b. That is, the left limit ring plate 51 is sleeved on the periphery of the left pre-limiting plate 21, and the inner ring size of the left limit ring plate 51 is larger than the outer ring size of the left pre-limiting plate 21. The left limit ring plate 51 is not used to support the workpiece, but only to better contact and limit the workpiece on the left side. Moreover, the left limit ring plate 51 is to be able to move left and right. The movement of the thermal insulation block stacking bearing moving frame b is very slow, because it needs to be heated and sintered for a long time in the furnace, so it needs to move very slowly. Then, after the moving frame enters, the left limit ring plate 51 needs to move to the right, especially the left rotation limit body 511 needs to be against the left side of the moving frame for limiting. Similarly, a corresponding limiting structure is also set on the right side. The spacing distance between the left rotation limit body 511 and the right rotation limit body 521 is obviously smaller than the spacing distance between the left pre-limiting plate 21 and the right pre-limiting plate 31, so that accurate limiting can be better performed. The left limiting annular plate 51 and the right limiting annular plate 52 can be connected to the corresponding existing left-right movable structures on the left and right sides.

[0030] Preferably, the left limiting annular plate 51 is also connected to a left elastic support connection assembly for elastically squeezing and abutting the left side of the insulation block stacking bearing moving frame b on the left side, and the right limiting annular plate 52 is also connected to a right elastic support connection assembly for elastically squeezing and abutting the right side of the insulation block stacking bearing moving frame b on the right side. The left elastic support connection assembly and the right elastic support connection assembly are both provided with a pressure sensor 6. The left elastic support connection assembly can be a structure in which a damping rod is connected to an ordinary shaft rod. The other end of the shaft rod is fixedly connected to the left limiting annular plate 51. The shaft rod can be set through the left side wall of the kiln, and the damping rod is on the outside. The other end of the damping rod can be connected to a cylinder or a linear motor that moves left and right for it to move left and right. In this way, the left limiting annular plate 51 can move left and right, and the squeezing and abutting of the left rotating limiting body 511 can have a certain elastic force, reducing hard damage. The damping rod can also be replaced by a spring. The right side structure is set with reference to the left side. Furthermore, the left inner rotating bearing 411 and the right inner rotating bearing 421 are both high-temperature bearings, and the left rotating limiter 511 and the right rotating limiter 521 are both high-temperature universal balls. This material selection is convenient for use in the kiln, and does not affect the rotation of the roller and the smooth transportation of the workpiece. The pressure sensor 6 is mainly used to detect the extrusion force on the moving frame, and try to keep the left and right balance to avoid the uneven extrusion causing the transportation stability to decrease and affect the sintering of the insulation block, and notify the sensor to obtain data to adjust the left and right moving positions to change the pressure.

[0031] Furthermore, the left rotation limit body 511 has more than 4 and forms at least one annular array on the left limit ring plate 51, the right rotation limit body 521 has more than 4 and forms at least one annular array on the right limit ring plate 52, and the left support pipe pile 41 and the right support pipe pile 42 are both provided with a temperature detector 400.

[0032] Here, the left rotation limiter 511 and the right rotation limiter 521 are set as a full circle, which is suitable for the left limiter annular plate 51 and the right limiter annular plate 52 to rotate themselves. Taking the left limiter annular plate 51 on the left side as an example, in this structure, the aforementioned shaft rod is replaced by a sleeve s1 that can surround the left conveying roller g1. The left conveying roller g1 needs to be installed with a connecting bearing on the outside, and the sleeve s1 is sleeved on the bearing, and the right end of the sleeve is fixed on the left limiter annular plate 51. The left side of the left limiter annular plate 51 can be integrally connected with a connecting pipe s2 with the same aperture as the aperture of its inner ring. The sleeve s1 and the left end of the connecting pipe s2 are connected, and the outer periphery of the sleeve s1 can be provided with an annular groove s10 for connecting with the damping structure. For example, a roller or a universal wheel is installed and connected at the right end of the damping rod, and the roller or the universal wheel is placed in the annular groove s10, so that the left and right movement and the rotation of the left limiter annular plate 51 itself will not be affected. The right side structure can refer to the left side. The temperature detector 400 is set to detect temperature in all areas before and after. The purpose of the detection is to understand the heating stability of each area in the furnace so as to control the temperature. For example, the low temperature area can be further heated by the nozzle of the support tube, while the high temperature area can be blown to balance the heat.

[0033] The new design of the preparation mechanism mentioned above can optimize the sintering heating process. For example, the goal is to optimize the sintering heating parameters to make the temperature distribution of the blocks on the moving frame more uniform and the heating more thorough during the sintering process. The sintering process can be further optimized through the existing algorithm because so many sensors and detection structures are set up. For example, through the objective function: select a fitness function to quantify the temperature uniformity, such as: temperature standard deviation: hope to minimize the standard deviation of temperature. Maximum and minimum temperature difference: hope to minimize the difference between the maximum temperature and the minimum temperature in the furnace. And so on, the kiln can be more controllable and the sintering can be more controllable. It is conducive to the production of high-quality insulation blocks.

[0034] Embodiment 2, a preparation process of a one-time stacked insulating building block, is characterized in that the one-time stacked insulating building block preparation mechanism in embodiment 1 is used, and the specific process is as follows, including step 1: preparing raw materials, crushing the raw materials and mixing them to obtain a molding material, and this step can be prepared using existing materials and equipment; step 2: molding the molding material to form an insulating building block blank and drying the insulating building block blank to form an intermediate material. The molding material in step 1 is relatively wet, and is placed in an existing molding equipment for molding to obtain an insulating building block blank with a final shape. The insulating building block blank will become an intermediate material after drying, and the intermediate material is actually an insulating building block blank with reduced moisture; step 3: placing the intermediate material into the insulating building block stacking carrying moving frame b for stacking, and placing the insulating building block stacking carrying moving frame b filled with insulating building blocks into the kiln 1 for one sintering to form the insulating building block final material. By sintering once in the kiln of embodiment 1, a better insulating building block can be obtained. Of course, during step 3, since there are many sensors and auxiliary equipment in the equipment, it is possible to make timely adjustments based on the on-site processing conditions to better optimize the sintering process.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
