Description

Wet breaking machine for aerated concrete building blocks or plates

Technical Field

Background

In the field of autoclaved aerated concrete material production, autoclaved aerated concrete blocks are porous concrete products prepared from siliceous materials (such as yellow sand) and calcareous materials (lime and cement) serving as raw materials through the procedures of batching and metering, stirring and pouring, static curing and cutting, autoclaved curing and the like. The autoclaved aerated concrete plate is a porous concrete product internally provided with a steel bar net cage with a certain specification, which is preset in the autoclaved aerated concrete block. However, in the production process of autoclaved aerated concrete blocks or plates, the siliceous material and the calcareous material undergo hydration reaction when being steamed at high temperature, so that the finished products of the blocks or plates are adhered together, and therefore, the finished products of the blocks and plates need to be separated.

In a traditional autoclaved aerated concrete block plate production line, a finished block plate product after steam curing is generally subjected to breaking treatment, which is called dry breaking. However, when the 'dry breaking' process is adopted, the finished product of the block board can be broken off only by a large breaking force due to large adhesive force between the finished product of the block board, which is easy to cause damage to the finished product, especially for thin and long boards, the 'dry breaking' is very easy to damage the finished product to cause breaking failure. The other mode is that before the block board is steamed, the semi-finished product of the block blank is subjected to splitting treatment, which is called wet splitting. The semi-finished products are broken off in a wet breaking mode, the blank does not undergo high-temperature hydration reaction, the semi-finished products are small in adhesive force, and the semi-finished products are suitable for breaking off, and are particularly suitable for breaking off thin and long plates.

The upper base 513 is fixedly installed inside the upper end of the frame 2, and the upper snapping-off telescopic mechanism 511 and the upper clip 512 have a plurality of pairs. The upward snapping telescopic mechanism 511 is disposed on the upper base 513 at equal intervals perpendicular to the feeding direction, and the telescopic member extends downward along the height direction and is fixedly connected with an upper clamping member 512. In this embodiment, the upward snapping telescopic mechanism 511 is a cylinder, the cylinder body of the cylinder is fixedly connected to the upper base 513, the end of the piston rod is fixedly connected to the upper clamping member 512, and three pairs of upward snapping telescopic mechanisms 511 and upper clamping members 512 are provided on a single base 513. The upward snapping-off means 51 has a plurality of upper snapping-off members arranged at equal intervals along the feeding direction at the upper end of the frame 1, and therefore, the present embodiment finally forms three rows of upper clips 512 arranged perpendicular to the feeding direction at the upper end of the frame 1.

The lifting motor 531 is in transmission connection with a lifting speed reducer 532, and the lifting speed reducer 532 drives a lifting rotating shaft 533 to rotate. The plurality of screw lifting mechanisms 534 are arranged along the length direction of the rack 2 and fixedly connected with the rack 2, and the lifting rotating shaft 533 penetrates through the plurality of screw lifting mechanisms 534 and is in screw transmission connection with the screw therein. The lead screw of the lead screw lifting mechanism 534 extends along the height direction, the upper end of the lead screw is connected with the downward snapping device 52 through a bearing, and the outer side of the lower end is sleeved with a protective sleeve connected with the base of the lead screw lifting mechanism 534. The mode that the rotating shafts which rotate synchronously drive the plurality of lead screw lifting mechanisms 534 to work synchronously can ensure the working synchronism among the plurality of lead screw lifting mechanisms 534, enhance the splitting precision of the blank body and avoid the damage of the blank body.

As shown in fig. 7, the breaking-down device 52 has a plurality of pairs corresponding to the number of the lead screw elevating mechanisms 534, and includes a breaking-down expansion mechanism 521, a lower clip 522, and a lower base 523, and the breaking-down expansion mechanism 521 and the lower clip 522 have a plurality of pairs. The downward snapping telescopic mechanism 521 is disposed on the lower base 523 at equal intervals perpendicular to the feeding direction, and the telescopic member extends upward along the height direction and is fixedly connected to a lower clamping member 522. In this embodiment, the plurality of lower susceptors 523 are mounted together on a long connecting frame, and the lead screw of the lead screw elevating mechanism 534 is connected to the lower end surface of the connecting frame through a bearing. The downward breaking-off telescopic mechanism 521 is a cylinder, the cylinder body of the cylinder is fixedly connected with a lower base 523, the end part of a piston rod of the cylinder is fixedly connected with a lower clamping piece 522, and three pairs of downward breaking-off telescopic mechanisms 521 and the lower clamping piece 522 are arranged on a single base 523. The lower breaking-off devices 52 are arranged at equal intervals along the feeding direction at the lower end of the frame 1, so that three rows of lower clamping pieces 522 arranged perpendicular to the feeding direction are finally formed at the lower end of the frame 1, and the positions of each row of lower clamping pieces 522 and the plurality of rows of upper clamping pieces 512 of the upper breaking-off device 51 correspond to each other, i.e. are in the same height direction. In this embodiment, the pressure when the downward separating and stretching mechanism 521 extends needs to be greater than the pressure when the upward separating and stretching mechanism 511 extends, so that when the lifting device 53 jacks, the upward separating and stretching mechanism 511 contracts, and the green body is jacked up and is higher than the rest of the green bodies by a certain height, thereby completing the separating.

As shown in fig. 9, the plurality of lifting guide mechanisms 54 are arranged at equal intervals along the feeding direction, and each lifting guide mechanism includes a connecting block 541, a vertical guide rail 542, and a vertical sliding seat 543. Wherein, vertical guide rail 542 sets up on connecting block 541 and extends along the direction of height, and connecting block 541 breaks the link fixed connection of device 52 with breaking off with the fingers and thumb down, and vertical slide 543 fixed mounting is in frame 2 and cooperatees with vertical guide rail 542. The lifting guide mechanism 54 can ensure the direction accuracy of the downward separating device 52 during lifting, improve the clamping precision of the green body and prevent the green body from being damaged in the clamping process.

When clamping the blank, the cylinders of the upper breaking-off device 51 and the lower breaking-off device 52 which are positioned in the same height direction extend out to tightly push the upper end of one layer of blank, and the rest cylinders keep a contraction state. Then, the lifting device 53 works to drive the lower breaking-off device 52 to ascend, so that the upper clamping piece 512 and the lower clamping piece 522 clamp the green bodies, and then the transverse driving device 3 works to move the frame 2 and drive the clamped green bodies to move, thereby completing the breaking-off of a layer of green bodies. In actual work, when the blank thickness is small, the blank can be clamped only by selecting the single-row telescopic mechanism, when the blank thickness is large, the width of the clamping piece on the single-row telescopic mechanism is smaller than the blank thickness, so that the blank cannot be clamped, and at the moment, the blank can be clamped by adopting the joint work of the multiple-row telescopic mechanism. Therefore, according to the embodiment, the blank clamping operation can be selectively performed by adopting the single-row telescopic mechanisms or the multi-row telescopic mechanisms with different sizes according to the blanks with different thicknesses, the application range of the wet breaking machine to the thickness of the blanks is increased, and the practicability of the wet breaking machine is improved.

However, the above-mentioned way of clamping the blank up and down also has a certain problem, that is, the bottom of the existing horizontal steam-curing bottom plate is required to bear the blank, so the lower clamp 522 can not tightly push the blank from the lower part of the blank. In response to this problem, the present embodiment takes the following measures.

As shown in fig. 10, the horizontal steam-curing bottom plate 6 includes a pair of side plates 61 arranged in parallel, the side plates 61 are connected by a plurality of long blocks 62, the long blocks 62 are arranged at equal intervals along the length direction of the side plates 61, and a gap through which the lower clamping member 522 can pass is formed between the adjacent long blocks 62. The upper ends of the telescopic members of the row of downward snapping telescopic mechanisms 521 are connected with a long seat 524, the long seat 524 extends along the feeding direction, and a plurality of lower clamping members 522 are arranged on the long seat 524 at equal intervals along the length direction and correspond to the gaps of the horizontally arranged steam-curing bottom plate 6 one by one. By the mode, the problem that the blank body on the traditional transverse steam curing bottom plate is difficult to clamp up and down is solved skillfully, the design is simple and skillful, and the installation and the operation are convenient.

It is worth mentioning that, in order to prevent that the horizontal steam-curing bottom plate 6 from moving on the bottom plate conveying device 4 when clamping the blank body, thereby resulting in that the blank clamping precision is influenced, the blank body is impaired, even the problem of blank clamping failure appears, the embodiment has set up bottom plate positioner 7. As shown in fig. 11, the bottom plate positioning device 7 includes a positioning frame 71 and a positioning cylinder 72, wherein the positioning frame 71 is fixedly mounted on the base 1, and a through hole is formed in the positioning frame to penetrate through the base. The cylinder body of the positioning cylinder 72 is fixedly mounted on the positioning frame 71, the piston rod of the positioning cylinder extends upwards and penetrates through the through hole, meanwhile, the side plate 61 is provided with a positioning hole 63 for the piston rod to penetrate through, and a plurality of positioning holes 63 are formed in the single side plate 61 along the length direction of the single side plate in the embodiment. After the transverse steam-curing bottom plate 6 reaches a preset position, a piston rod of the positioning cylinder 72 extends upwards to penetrate through the positioning hole 63 in the side plate 61, so that the transverse steam-curing bottom plate 63 stays at the preset position, and the phenomenon that the blank body is damaged and fails to be broken due to movement of the transverse steam-curing bottom plate in the blank clamping process is prevented. In order to further enhance the positioning effect on the horizontal steam-curing bottom plate 6, in the embodiment, the front side and the rear side of the base 1 are respectively provided with one positioning device 7, so that the positioning on the horizontal steam-curing bottom plate 6 is more stable.

In summary, the wet breaking-off machine for aerated concrete blocks or boards in the embodiment is different from a conventional wet breaking-off machine, and can break off the transversely stacked green bodies through the transverse driving device 3, the upper breaking-off device 51, the lower breaking-off device 52 and the lifting device 53, so that the situation that the green bodies are easily damaged or even failed to break off the vertically stacked green bodies due to large binding force caused by gravity of the green bodies when the conventional breaking-off machine breaks off the vertically stacked green bodies is avoided. The wet breaking machine has the advantages of ingenious structure, high breaking efficiency and high breaking accuracy, does not easily damage the blank body, and improves the yield of concrete blocks or plates.

Example 2

A wet breaking-off method for aerated concrete blocks or plates is characterized in that a wet breaking-off machine for aerated concrete blocks or plates in embodiment 1 is adopted to carry out breaking-off treatment on green bodies before steam curing, and the specific process is as follows:

firstly, conveying and positioning of bottom plate

As shown in fig. 12, when the devices of the wet-break machine are in the initial state, the conveying motor 42 in the bottom plate conveying device 4 is operated to drive the conveying shaft 43 and the wheels 44 to rotate, the horizontal steam-curing bottom plate 6 carrying the concrete blanks is driven to be conveyed to the working position, and the plurality of concrete blanks are bonded together on the horizontal steam-curing bottom plate 6 along the horizontal direction. Then, the bottom plate positioning device 7 works, and the piston rod of the positioning cylinder 72 extends out and penetrates through the positioning hole 63 on the transverse steam-curing bottom plate 6, so that the transverse steam-curing bottom plate 6 is positioned. At this time, the lower clip 522 of the downward snapping apparatus 52 is just under the gap between the bars 62 of the horizontally placed steam-curing floor 6.

Selection of second, break-off chuck

As shown in fig. 13, one row of clips or multiple rows of clips located at the same height of the severing assembly 5 are selected according to the thickness of the single-layer blank. The upper breaking-off telescopic mechanism 511 and the lower breaking-off telescopic mechanism 521 are controlled to work, so that the selected row of upper clamping pieces 512 and the selected row of lower clamping pieces 522 are driven to extend, and the rest of the upper clamping pieces 512 and the rest of the lower clamping pieces 522 are driven to contract. Wherein the protruding upper clamp 512 presses the top end of the outermost layer of the blank.

Thirdly, jacking and breaking off

As shown in fig. 14, the lifting device 53 is operated, the lifting motor 531 is operated, and the lifting shafts 533 drive the screw lifting mechanisms 534 to operate, so as to lift the lower breaking-off device 52, wherein during the lifting process, the selected row of lower clamping pieces 522 in the lower breaking-off device 52 is kept in the extending state. With the lifting of the lifting device 53, the lower clamping member 522 kept in the extended state contacts the blank and continuously lifts, and since the internal pressure of the lower snapping mechanism 521 (in this embodiment, a cylinder) is greater than the internal pressure of the upper snapping mechanism 511 (in this embodiment, a cylinder), the upper snapping mechanism 511 is compressed, so that the clamped blank is lifted and forms a height difference with the rest of the blank, and the lifting snapping process is completed.

Fourthly, moving and separating

As shown in fig. 15, after the lifting and snapping are completed, the clamping state of the green bodies is maintained, the transverse driving device 3 operates, the transverse motor 31 controls the transverse rotating shaft 33 to rotate, and drives each lead screw and nut mechanism 34, so as to drive the rack 2 to move transversely towards the outer side of the base 1, and after the rack 2 moves transversely for a certain distance, a gap is formed between one layer of green bodies on the outermost side and the rest of green bodies, and the moving and separating are completed.

Fifthly, breaking off layer by layer
