Description

Technical Field

[0001] The invention relates to the technical field of fire-resistant heat-insulating boards, and in particular to production equipment and a production process of large-size floating bead fire-resistant heat-insulating boards. Background Art

[0002] Floating bead fireproof insulation board is a high-performance thermal insulation material, mainly composed of floating beads, refractory materials and binders. Floating beads are lightweight, hollow microspheres with low density, high strength and good thermal insulation performance.

[0003] In the prior art, when producing floating bead refractory insulation boards, firstly, floating beads, refractory materials and binders are mixed in a certain proportion to form slurry, then a layer of demoulding oil is applied in a horizontal mold to facilitate the later demoulding of the board, and finally the prepared slurry is poured into the horizontal mold to form a board, the formed board is dried, and then sliced ​​into layers.

[0004] The floating bead refractory insulation board produced according to this production method has the following disadvantages: 1. Small size. The maximum size of the floating bead fire-resistant insulation board produced by this method is 1200mm*1200mm. If the size is larger, the board is prone to breakage. Therefore, multiple pieces of the board need to be spliced ​​together during installation. The fireproof ability of the joints is relatively weak. If there are too many joints, its fireproof ability will be affected. 2. The cost is high. Applying mold release oil and slicing in the horizontal mold is costly, inefficient, and difficult to construct. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the floating bead refractory insulation board produced by horizontal grouting in the prior art, which is small in size, easy to break and has high processing cost, the present invention provides a production equipment and a production process for large-size floating bead refractory insulation board.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a production equipment for large-size floating bead refractory insulation boards, including a bracket, a plurality of spaced vertical plates are slidably connected to the bracket along the length direction, two adjacent vertical plates are detachably connected with two side plates and a bottom plate, one side of the bracket is provided with a first unwinding roller for unwinding a release film and a second unwinding roller for unwinding a mesh cloth, the first unwinding roller is arranged below the second unwinding roller, a clamping assembly for clamping the release film and the end of the mesh cloth is provided on the side of the bracket away from the first unwinding roller and the second unwinding roller, a pressing tube is provided above the bracket, and a driving assembly is provided on the pressing tube for driving the pressing tube to move along the length direction of the bracket and driving the pressing tube to move in the vertical direction.

[0007] According to the required thickness of the fire-resistant insulation board to be processed, the side plate and the bottom plate of appropriate thickness are selected, and they are matched with the vertical plate to form a vertical cavity; the first unwinding roller is used to unwind the release film, the second unwinding roller is used to unwind the mesh, and the clamping assembly is used to clamp the ends of the release film and the mesh; the release film and the mesh are laid in a U shape in a single vertical cavity, and the release film and the mesh are laid in a continuous S shape in multiple vertical cavities, and the release film is attached to the inner wall of the vertical plate and the upper wall of the bottom plate. The driving assembly is used to drive the pressure tube to move horizontally and vertically. The pressure tube moves horizontally to move above each vertical cavity, and the pressure tube moves vertically to press down the release film and mesh so that it fits the inner wall of the vertical cavity. The fire-resistant insulation board produced by this equipment has mesh on both sides, which has higher overall strength and is not easy to break. Using release film instead of lubricating oil can reduce the cost by 70%, and the lubricating oil will leak, which is not conducive to maintaining the cleanliness of the production site. Using release film instead of lubricating oil can achieve clean production.

[0008] Furthermore, in order to facilitate the demoulding of the fire-resistant insulation board, the bracket includes an upper frame and a lower frame, the upper frame and the lower frame are slidably connected in the vertical direction, a plurality of lifting rings are provided on the upper frame, a slide groove is provided on the upper frame along the length direction, and pulleys are connected to both ends of the vertical plate through connecting plates, and the pulleys are embedded in the slide grooves.

[0009] Furthermore, in order to clamp the release film and one end of the mesh cloth, the clamping assembly includes a pressing plate, which is arranged above the upper frame, and cylinders for driving the pressing plate to move closer to or away from the upper frame are arranged at both ends of the pressing plate.

[0010] Furthermore, in order to fix the positions of each vertical plate, side plate and bottom plate, a limit plate cooperating with the vertical plate is provided on the side of the upper frame close to the first unwinding roller, and a pressure rod cooperating with the vertical plate is threadedly connected in the horizontal direction on the side of the upper frame away from the first unwinding roller, and the position of the pressure rod corresponds to the position of the side plate, a rubber pad is provided on the end of the pressure rod close to the vertical plate, and a connecting hole cooperating with the crowbar is provided on the end of the pressure rod away from the vertical plate.

[0011] By rotating the pressure rod along the thread, the sidemost vertical plate is squeezed, so that each vertical plate, side plate and bottom plate are moved closer to the limit plate, thereby fixing the position of each vertical plate, side plate and bottom plate, making it easier to grout into each vertical cavity.

[0012] Furthermore, the driving assembly includes a connecting tube, and the connecting tubes are provided at both ends of the pressing tube. The pressing tubes are pressed down along each vertical cavity, so that the release film and the mesh cloth can be closely attached to the inner wall of the vertical cavity.

[0013] The connecting pipe can be driven by a crane or manpower, which makes it easy to insert the pressure pipe into the vertical cavity to smooth the release film and mesh cloth in the vertical cavity. After grouting in the vertical cavity, the pressure pipe can be moved up and down in the vertical cavity to discharge the bubbles in the slurry.

[0014] Furthermore, heating devices are provided on both sides of the vertical plate. When the ambient temperature is lower than 0°C, the slurry temperature is maintained at about 20°C by starting the heating devices on both sides of the vertical plate and the bracket, which facilitates the rapid molding of the slurry and improves production efficiency.

[0015] Furthermore, in order to discharge the bubbles in the slurry in the vertical cavity, a vibration device is provided on the bracket.
