Description

Technical Field

[0001] The present invention belongs to the field of concrete material processing equipment, and more specifically, relates to a wet splitting machine for autoclaved aerated concrete blocks or plates. Background Art

[0002] In the field of autoclaved aerated concrete material production, autoclaved aerated concrete blocks are porous concrete products made from siliceous materials (such as yellow sand) and calcareous materials (lime and cement) through processes such as batching and metering, mixing and pouring, static curing and cutting, and autoclave curing. Autoclaved aerated concrete plates are porous concrete products with a pre - installed steel mesh cage of a certain specification inside the autoclaved aerated concrete blocks. However, during the production process of autoclaved aerated concrete blocks or plates, the siliceous material and the calcareous material will undergo a hydration reaction during high - temperature steam curing, causing the finished blocks or plates to stick together. Therefore, it is necessary to split the finished blocks and plates.

[0003] In traditional autoclaved aerated concrete block and plate production lines, the finished blocks and plates after steam curing are usually split, which is called "dry splitting". However, when using the "dry splitting" process, due to the large adhesion force between the finished blocks and plates, a large splitting force is required to split them, which easily causes damage to the finished products. Especially for thin and long plates, "dry splitting" is very likely to damage the finished products and result in splitting failure. Another method is to split the semi - finished block blanks before steam curing, which is called "wet splitting". Since "wet splitting" is to split semi - finished products and the blanks have not undergone high - temperature hydration reaction, the adhesion force between the semi - finished products is small, which is suitable for splitting, especially suitable for splitting thin and long plates.

[0004] The Chinese patent application number is: CN201420809208.3, and the publication date is: June 17, 2015. The patent document discloses a block separator and its splitting traction device. In the splitting traction device, the bearing frame is connected to the fixed clamping device through the bearing arm, the moving clamping device is connected through the lifting arm of the lifting frame, and the lifting of the lifting frame on the bearing frame is realized by the pushing of the separation driving device between the bearing beam and the lifting beam, and drives the moving clamping device to move up and down relative to the fixed clamping device. In this utility model, the splitting traction device will improve the splitting synchronism on both sides of the block layer and ensure the reliability of block splitting.

[0005] The Chinese patent application number is CN201920696234.2, and the patent document with the publication date of February 28, 2020 discloses a sand aerated concrete block production mechanism, including two third beams, the two third beams are arranged in parallel, and vertical downward support rods are installed on the bottom surface of the third beams, and a number of first beams are arranged between the support rods, and the first beams are arranged in layers from top to bottom. Guide seats are connected at both ends of the first beam, and the support rods are all penetrated through the guide seats, and the guide seats and the support rods are connected by linear bearings; the support rods are fixedly installed on the mounting base; the outer side of the guide seat is installed with a connecting plate extending outward and arranged horizontally, and two first through-holes are also provided in the middle of the guide seat. This utility can clamp the stacked bricks at the same time at one time, and the bricks are separated layer by layer under the drive of the lifting cylinder, so that multiple bricks can be split at one time. The process is simple and practical, and the operation is convenient.

[0006] The above two solutions are both breaking devices for breaking concrete blocks or panels, but both of them are for breaking up the cut blocks or panels stacked up and down. Since the blocks or panels stacked up and down are affected by their own gravity, the bonding force between each layer of blocks is relatively tight, which may easily cause damage to the finished product during breaking, or even cause the breaking to fail. Summary of the invention

[0051] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0052] Embodiment 1

[0053] A wet splitting machine for aerated concrete blocks or plates, which is used for splitting billets stacked horizontally together, mainly includes a base 1, a frame 2, a transverse driving device 3, a bottom plate transportation device 4, a splitting assembly 5, a horizontally placed curing bottom plate 6 and a bottom plate positioning device 7. The specific structure and working principle of this wet splitting machine will be described in detail below.

[0054] As Figure 1As shown, the base 1 and the frame 2 are the installation bases for each device of the wet splitting machine. Among them, there are a pair of frames 2, which are symmetrically installed on both sides of the base 1. It should be noted that the structures of the two frames 2 and the various components installed thereon are the same and are symmetrically arranged on the base 1. In this embodiment, only a single frame 2 and its installation components are described for convenience of description.

[0055] As Figure 2 shown, there are multiple bottom plate transportation devices 4, which are arranged on the base 1 along the feeding direction. Its specific structure is as Figure 5 shown, including a pair of conveying seats 41, a conveying motor 42, a conveying shaft 43 and wheels 44. Among them, a pair of conveying seats 41 are symmetrically and fixedly installed on both sides of the base 1. The conveying motor 42 is fixedly installed on one of the conveying seats 41. The output shaft of the conveying motor 42 is drivingly connected to one end of the conveying shaft 43. The other end of the conveying shaft 43 is connected to the other conveying seat 41 through a bearing and is horizontally arranged. There are two wheels 44, which are fixedly sleeved on both ends of the conveying shaft 43. The bottom of the horizontally placed curing bottom plate 6 is provided with structures such as tracks that cooperate with the wheels 44, and it can be supported on the wheels 44. When the conveying motor 42 works, it can drive the conveying shaft 43 and the wheels on the conveying shaft 43 to rotate, and control the horizontally placed curing bottom plate 6 to move along the feeding direction.

[0056] As Figure 2 and Figure 4 shown, the transverse driving device 3 includes a transverse motor 31, a transverse speed reducer 32, a transverse rotating shaft 33, a lead screw nut mechanism 34 and a pushing seat 35. The transverse motor 31 is drivingly connected to the transverse speed reducer 32, and the transverse speed reducer 32 drives the transverse rotating shaft 33 to rotate. There are multiple lead screw nut mechanisms 34, which are arranged along the length direction of the frame 2 and fixedly connected to the frame 2. Specifically, two rows of equally spaced pushing seats 35 are symmetrically arranged on both sides of the base 1. The nut of the lead screw nut mechanism 34 is fixedly connected to the frame. The lead screw is horizontally arranged perpendicular to the feeding direction. One end of the lead screw is connected to the pushing seat 35 on one side of the base 1 through a bearing. A protective sleeve connected to the nut is sleeved on the outer side of the other end of the lead screw, which can prevent external dust, etc. from falling on the lead screw and affecting the normal operation of the lead screw. The transverse rotating shaft 33 passes through the nuts of multiple lead screw nut mechanisms 34 at the same time and is in spiral transmission connection with each lead screw. Therefore, when the transverse motor 31 works, the rotation of the transverse rotating shaft 33 can drive each lead screw to rotate, so that each nut moves along the lead screw, driving the frame 2 fixedly connected to the nut to move perpendicular to the feeding direction. This method of using a synchronously rotating rotating shaft to drive multiple lead screw nut mechanisms 34 to work synchronously can ensure the working synchronism between the multiple lead screw nut mechanisms 34, enhance the splitting accuracy of the green body, and avoid damage to the green body.

[0057] As Figure 3As shown, the splitting assembly 5 includes an upper splitting device 51, a lower splitting device 52, a lifting device 53, and a lifting guiding mechanism 54.

[0058] As Figure 6 shown, the upper splitting device 51 includes an upper splitting telescopic mechanism 511, an upper clamping member 512, and an upper base 513. The upper base 513 is fixedly installed on the inner side of the upper end of the frame 2. There are multiple pairs of the upper splitting telescopic mechanism 511 and the upper clamping member 512. Among them, the upper splitting telescopic mechanisms 511 are arranged at equal intervals on the upper base 513 perpendicular to the feeding direction, and their telescopic members extend downward in the height direction and are fixedly connected to an upper clamping member 512. In this embodiment, the upper splitting telescopic mechanism 511 uses a cylinder. The cylinder block is fixedly connected to the upper base 513, and the end of its piston rod is fixedly connected to the upper clamping member 512. There are three pairs of the upper splitting telescopic mechanisms 511 and the upper clamping members 512 provided on a single base 513. There are multiple upper splitting devices 51, which are arranged at equal intervals along the feeding direction at the upper end of the frame 1. Therefore, in this embodiment, three rows of upper clamping members 512 are finally formed at the upper end of the frame 1 perpendicular to the feeding direction.

[0059] As Figure 8 shown, the lifting device 53 is installed on the lower end face of the frame 2 and includes a lifting motor 531, a lifting speed reducer 532, a lifting rotating shaft 533, and a screw rod lifting mechanism 534. The lifting motor 531 is in transmission connection with the lifting speed reducer 532, and the lifting speed reducer 532 drives the lifting rotating shaft 533 to rotate. There are multiple screw rod lifting mechanisms 534, which are arranged along the length direction of the frame 2 and fixedly connected to the frame 2. The lifting rotating shaft 533 passes through multiple screw rod lifting mechanisms 534 and is simultaneously in screw transmission connection with the screw rods therein. The screw rods of the screw rod lifting mechanism 534 extend in the height direction, the upper ends of which are connected to the lower splitting device 52 through bearings, and the outer sides of the lower ends are sleeved with protective sleeves connected to the bases of the screw rod lifting mechanism 534. This method of using a synchronously rotating rotating shaft to drive multiple screw rod lifting mechanisms 534 to work synchronously can ensure the working synchronism between multiple screw rod lifting mechanisms 534, enhance the splitting accuracy of the blank, and avoid damage to the blank.

[0060] As Figure 7As shown in the figure, there are multiple lower splitting devices 52, the number of which corresponds to the number of screw rod lifting mechanisms 534. It includes a lower splitting telescopic mechanism 521, a lower clamping member 522, and a lower base 523. There are multiple pairs of the lower splitting telescopic mechanism 521 and the lower clamping member 522. Among them, the lower splitting telescopic mechanisms 521 are arranged at equal intervals on the lower base 523 perpendicular to the feeding direction, and its telescopic member extends upward in the height direction and is fixedly connected to a lower clamping member 522. In this embodiment, multiple lower bases 523 are jointly installed on a long strip-shaped connecting frame, and the screw rod of the screw rod lifting mechanism 534 is connected to the upper end surface of the connecting frame through a bearing. The lower splitting telescopic mechanism 521 adopts a cylinder, the cylinder block of which is fixedly connected to the lower base 523, and the end of its piston rod is fixedly connected to the lower clamping member 522. Each single base 523 is provided with three pairs of the lower splitting telescopic mechanism 521 and the lower clamping member 522. The lower splitting devices 52 are arranged at equal intervals along the feeding direction at the lower end of the frame 1. Therefore, in this embodiment, three rows of lower clamping members 522 are finally formed at the lower end of the frame 1 perpendicular to the feeding direction, and the positions of each row of lower clamping members 522 correspond to those of multiple rows of upper clamping members 512 of the upper splitting device 51, that is, they are in the same height direction. In this embodiment, the pressure when the lower splitting telescopic mechanism 521 extends needs to be greater than the pressure when the upper splitting telescopic mechanism 511 extends, so that when the lifting device 53 jacks up, the upper splitting telescopic mechanism 511 can contract, the blank is jacked up and is higher than the other blanks by a certain height, and the splitting is completed.

[0061] As Figure 9 shown, there are multiple lifting guiding mechanisms 54, which are arranged at equal intervals along the feeding direction. It includes a connecting block 541, a vertical guide rail 542, and a vertical sliding seat 543. Among them, the vertical guide rail 542 is arranged on the connecting block 541 and extends in the height direction. The connecting block 541 is fixedly connected to the connecting frame of the lower splitting device 52, and the vertical sliding seat 543 is fixedly installed on the frame 2 and is matched with the vertical guide rail 542. The lifting guiding mechanism 54 can ensure the direction accuracy of the lower splitting device 52 during lifting, improve the clamping accuracy of the blank, and prevent the blank from being damaged during the clamping process.

[0062] When clamping the blank, the cylinders of the upper splitting device 51 and the lower splitting device 52 in the same height direction extend to tightly hold the upper end of a layer of blanks, and the remaining cylinders remain in a contracted state. Then the lifting device 53 operates to drive the lower splitting device 52 to rise, so that the upper clamping member 512 and the lower clamping member 522 clamp the blank. After that, the lateral driving device 3 operates to move the frame 2 and drive the clamped blank to move, completing the splitting of a layer of blanks. During actual operation, when the thickness of the blank is small, only a single-row telescopic mechanism can be selected to clamp the blank. However, when the thickness of the blank is large, the width of the clamping member on the single-row telescopic mechanism is smaller than the thickness of the blank, resulting in the inability to clamp the blank. At this time, a multi-row telescopic mechanism can be used to work together for blank clamping. Therefore, this embodiment can selectively use single-row telescopic mechanisms or multi-row telescopic mechanisms with different sizes for blank clamping operations according to blanks of different thicknesses, increasing the adaptation range of the wet splitting machine to the thickness of the blanks and improving the practicality of the wet splitting machine.

[0063] However, there are also certain problems with this way of clamping the blank from above and below. That is, since the bottom of the existing horizontally placed steam curing bottom plate needs to bear the blank, the lower clamping member 522 cannot perform a tightening operation on the blank from below the blank. To address this problem, the following measures are taken in this embodiment.

[0064] As Figure 10 shown, the horizontally placed steam curing bottom plate 6 includes a pair of parallel side plates 61, and the pair of side plates 61 are connected by long strips 62. There are multiple long strips 62, which are arranged at equal intervals along the length direction of the side plates 61, and gaps for the lower clamping member 522 to pass through are formed between adjacent long strips 62. The upper end of the telescopic member of a row of lower splitting telescopic mechanisms 521 is connected with a long strip seat 524. The long strip seat 524 extends along the feeding direction, and multiple lower clamping members 522 are arranged at equal intervals along its length direction, corresponding to the gaps of the horizontally placed steam curing bottom plate 6 one by one. In this way, the problem of difficult clamping of the blank on the traditional horizontally placed steam curing bottom plate from above and below is cleverly solved. The design is simple and ingenious, facilitating installation and operation.

[0065] It is worth mentioning that in order to prevent the horizontally placed steam curing bottom plate 6 from moving on the bottom plate transportation device 4 when clamping the blank, which may affect the clamping accuracy of the blank, damage the blank, or even cause the failure of blank clamping, a bottom plate positioning device 7 is provided in this embodiment. As Figure 11As shown in the figure, the bottom plate positioning device 7 includes a positioning frame 71 and a positioning cylinder 72. The positioning frame 71 is fixedly installed on the base 1 and is provided with a through hole penetrating up and down. The cylinder body of the positioning cylinder 72 is fixedly installed on the positioning frame 71, and its piston rod extends upward and passes through the through hole. At the same time, the side plate 61 is provided with a positioning hole 63 for the piston rod to pass through. In this embodiment, a plurality of positioning holes 63 are provided on a single side plate 61 along its length direction. When the horizontally placed curing bottom plate 6 reaches the predetermined position, the piston rod of the positioning cylinder 72 extends upward and passes through the positioning hole 63 on the side plate 61, so that the horizontally placed curing bottom plate 63 stays at the predetermined position, preventing the horizontally placed curing bottom plate from moving during the billet clamping process and causing damage to the billet and failure of splitting. In order to further strengthen the positioning effect on the horizontally placed curing bottom plate 6, a positioning device 7 is respectively provided on the front and rear sides of the base 1 in this embodiment, making the positioning of the horizontally placed curing bottom plate 6 more stable.

[0066] In summary, the wet splitting machine for aerated concrete blocks or plates in this embodiment is different from the traditional wet splitting machine. Through the horizontal driving device 3, the upper splitting device 51, the lower splitting device 52 and the lifting device 53, it can split the horizontally stacked billets, avoiding the situation that when the traditional splitting machine splits the vertically stacked billets, the billets have a large bonding force due to their own gravity, are easily damaged or even fail to split. This wet splitting machine has a clever structure, high splitting efficiency and accuracy, is not easy to damage the billets, and improves the yield of concrete blocks or plates.

[0067] Embodiment 2

[0068] A wet splitting method for aerated concrete blocks or plates uses the wet splitting machine for aerated concrete blocks or plates in Embodiment 1 to perform splitting treatment on the billets before steam curing. The specific process is as follows:

[0069] I. Bottom plate transportation and positioning

[0070] As Figure 12 shown, each device of the wet splitting machine is in the initial state. The conveying motor 42 in the bottom plate conveying device 4 works, driving the conveying shaft 43 and the wheels 44 to rotate, and driving the horizontally placed curing bottom plate 6 carrying the concrete billets to be transported to the working position. A plurality of concrete billets are bonded together horizontally on the horizontally placed curing bottom plate 6. Then, the bottom plate positioning device 7 works, and the piston rod of the positioning cylinder 72 extends out and passes through the positioning hole 63 on the horizontally placed curing bottom plate 6 to complete the positioning of the horizontally placed curing bottom plate 6. At this time, the lower clamping member 522 in the lower splitting device 52 is just under the gap between the long blocks 62 in the horizontally placed curing bottom plate 6.

[0071] II. Selection of splitting chuck

[0072] As Figure 13As shown, according to the thickness of a single-layer blank, one row of clamps or multiple rows of clamps of the splitting assembly 5 located at the same height is selected. In this embodiment, one row of clamps is selected. The upper splitting telescopic mechanism 511 and the lower splitting telescopic mechanism 521 are controlled to work, driving the selected row of upper clamps 512 and lower clamps 522 to extend, and the remaining upper clamps 512 and lower clamps 522 to retract. The extended upper clamps 512 press the top of the outermost layer of the blank.

[0073] 3. Lifting and splitting

[0074] like Figure 14 As shown, the lifting device 53 is working, the lifting motor 531 is working, and the lifting shaft 533 drives each screw lifting mechanism 534 to work, and the lower splitting device 52 is lifted. During the lifting process, the selected row of lower clamps 522 in the lower splitting device 52 remain in an extended state. As the lifting device 53 is lifted, the lower clamps 522 that remain in an extended state contact the embryo and continue to lift. Since the internal pressure of the lower splitting telescopic mechanism 521 (a cylinder in this embodiment) is greater than the internal pressure of the upper splitting telescopic mechanism 511 (a cylinder in this embodiment), the upper splitting telescopic mechanism 511 is compressed, so that the clamped embryo is lifted and forms a height difference with the rest of the embryo, completing the lifting and splitting process.

[0075] 4. Mobile Separation

[0076] like Figure 15 As shown, after the lifting and breaking are completed, the clamping state of the blank is maintained, the transverse drive device 3 works, and the transverse motor 31 controls the rotation of the transverse shaft 33, driving each screw and nut mechanism 34, thereby driving the frame 2 to move laterally toward the outside of the base 1. After the frame 2 moves laterally for a distance, the outermost layer of the blank forms a gap with the remaining blanks, completing the movement and separation.

[0077] 5. Break it down layer by layer

[0078] like Figure 16 As shown, after the outermost blank is moved and separated, the lifting device 53 is reset, and the outermost single-layer blank stays on the horizontal steaming bottom plate 6. At the same time, the upper breaking and telescopic mechanism 511 is reset, and the lower breaking and telescopic mechanism 521 remains in the extended state. The horizontal driving device 3 works to move the breaking assembly 5 to the next breaking position, preparing for the next breaking.

[0079] 6. Complete the split

[0080] like Figure 17 As shown, the splitting assembly 5 repeats steps 1 to 5 until a certain spacing size is maintained between each layer of the blanks, and the splitting of all the blanks is completed.

[0081] It is worth mentioning that the splitting components 5 on the two racks 2 of this embodiment can simultaneously perform splitting operations on the green bodies on both sides, greatly improving the splitting efficiency of the green bodies.

[0082] The embodiments described in the present invention are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design idea of the present invention, various deformations and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope of the present invention.
