Description

Technical Field

[0001] This utility model relates to the technical field of multilayer composite pressing equipment, specifically to a multilayer composite pressing device for low thermal conductivity refractory materials. Background Technology

[0002] Low thermal conductivity refractory materials refer to refractory materials with low thermal conductivity under high temperature conditions. They are mainly used to reduce heat transfer and improve the thermal efficiency and service life of equipment. Multilayer composite pressing of low thermal conductivity refractory materials is a technology that combines and press refractory materials with different properties into layers. It aims to optimize the thermal insulation performance, mechanical strength and thermal shock resistance of the materials. When performing multilayer composite pressing of low thermal conductivity refractory materials, a composite pressing device is required.

[0003] When performing multi-layer composite pressing of low thermal conductivity refractory materials, the powder or preform is loaded into the mold in layers according to the design sequence, and pressure is applied layer by layer to control the density of each layer. However, it is necessary to avoid delamination between layers. Inorganic binders (such as phosphates) or organic temporary binders can be added between layers to enhance the bonding force, and finally the multi-layer composite pressing of low thermal conductivity refractory materials is completed.

[0004] However, after multiple pressing operations, the mold of the current multi-layer composite pressing device will have some material residue. If these residues are not cleaned, they will affect the pressing quality of the subsequent low thermal conductivity refractory materials. Therefore, we propose a multi-layer composite pressing device for low thermal conductivity refractory materials. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments. Example 1:

[0030] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a multilayer composite pressing device for low thermal conductivity refractory materials, comprising:

[0031] Workbench 1, with a support 2 fixedly connected to the top of the workbench 1, a cylinder 3 installed on the support 2, an upper pressure mold 4 fixedly connected to the telescopic end of the cylinder 3, a composite mold 5 set in the middle of the workbench 1, and a lower pressure mold 8 installed at the bottom of the workbench 1.

[0032] The extension end of cylinder 3 pushes the upper die 4 downward, cooperating with the lower die 8 to press the material inside the composite mold 5.

[0033] The cleaning mechanism 7 includes a drive motor 701 fixedly connected to the bottom of the workbench 1. The drive motor 701 is fixedly connected to a lead screw 702 via an output shaft. An L-shaped plate 704 is threadedly connected to the outside of the lead screw 702. A spring 707 is fixedly connected to the outside of the L-shaped plate 704. A mounting plate 710 is fixedly connected to the other end of the spring 707. A rotating tube 705 is movably connected to the mounting plate 710 via a bearing. Hollow strips 709 are fixedly connected to both ends of the rotating tube 705. An L-shaped nylon brush 708 is fixedly connected to the outside of the hollow strips 709. A servo motor 713 for driving the rotating tube 705 to rotate is mounted on the mounting plate 710.

[0034] The drive motor 701 drives the lead screw 702 to rotate through the output shaft. The rotation of the lead screw 702 drives the L-shaped plate 704 and the mounting plate 710 to move, thereby moving the nylon brush 708 above the composite mold 5.

[0035] When the upper mold 4 moves downward under the action of the spring 707, it can push the lower nylon brush 708 into the composite mold 5. After cleaning, the spring 707 can reset the mounting plate 710, making it easy to remove from the composite mold 5 for subsequent cleaning.

[0036] Specifically, a vertical rod 706 is fixedly connected to the bottom of the mounting plate 710, and the other end of the vertical rod 706 passes through the L-shaped plate 704 and is slidably connected to the L-shaped plate 704.

[0037] The vertical rod 706 limits the movement trajectory of the mounting plate 710, ensuring that the mounting plate 710 can only move in the up and down direction. This allows the nylon brush 708 located below to be pushed into the interior of the composite mold 5 by the upper pressure mold 4, so as to clean the interior of the composite mold 5.

[0038] Specifically, a limiting rod 703 is fixedly connected to the outer side of the workbench 1, and the other end of the limiting rod 703 passes through the L-shaped plate 704 and is slidably connected to the L-shaped plate 704.

[0039] The movement trajectory of the L-shaped plate 704 is limited by the limit rod 703, ensuring that the L-shaped plate 704 can only move in the forward and backward directions. This allows the drive motor 701 to move towards the composite mold 5 for cleaning or move away from the composite mold 5 to reset the mounting plate 710, facilitating subsequent pressing of the material.

[0040] Specifically, a driven gear 712 is fixedly connected to the outside of the rotating tube 705, and a driving gear 711 is fixedly connected to the servo motor 713 through the output shaft. The outside of the driving gear 711 meshes with the outside of the driven gear 712.

[0041] The servo motor 713 drives the drive gear 711 to rotate via the output shaft. The drive gear 711 rotates, which in turn drives the driven gear 712 to rotate. The driven gear 712 rotates, which in turn drives the rotating tube 705 to rotate. The rotating tube 705 rotates, which in turn drives the hollow strip 709 to rotate. The nylon brush 708 on the outer side of the hollow strip 709 cleans the composite mold 5, the upper mold 4, and the lower mold 8. Example 2:

[0042] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0043] The dust collection mechanism 6 includes a filter box 602 fixedly connected to the outside of the mounting plate 710. A negative pressure fan 601 extending into the filter box 602 is provided on the outside of the filter box 602. A cover 607 is rotatably connected to the outside of the rotating pipe 705. An air duct 603 communicating with the inside of the cover 607 is fixedly connected to the outside of the cover 607.

[0044] The suction force generated by the negative pressure fan 601 draws the material debris cleaned by the cleaning mechanism 7 into the filter box 602. The filter screen 605 filters the incoming material debris, facilitating subsequent unified processing.

[0045] Specifically, a slot 606 is provided on the outside of the filter box 602, and a washable filter screen box 605 is provided inside the slot 606. The other end of the air duct 603 is fixedly connected to the top of the filter box 602 and communicates with the inside of the filter box 602.

[0046] The slot 606 facilitates the installation and removal of the filter box 605. The air duct 603 allows air to be drawn from the hollow strip 709 through the cover 607, connecting hole 609 and rotating tube 705, thereby generating suction in the dust collection slot 604 to clean the material residue in the composite mold 5.

[0047] Specifically, the two ends of the rotating tube 705 are connected to the interior of the corresponding hollow strip 709, and the two hollow strips 709 are provided with dust collection grooves 604 on the side away from each other.

[0048] The suction tank 604 can suck up the material residue inside the composite mold 5, making it convenient to clean the material residue inside the composite mold 5, ensuring its cleanliness and guaranteeing the quality of subsequent material pressing.

[0049] Specifically, a support block 608 is fixedly connected to the outside of the cover 607, and the support block 608 is fixedly connected to the outside of the mounting plate 710.

[0050] The support block 608 supports the position of the cover 607, ensuring the stability of the cover 607 and making the cover 607, air duct 603, connecting hole 609 and rotating pipe 705 internally connected, so as to clean up material residue.

[0051] The remaining structure is the same as that in Example 1.

[0052] The workflow of this utility model is as follows:

[0053] After multiple pressing operations by the multi-layer composite pressing device, the drive motor 701 is started. The drive motor 701 drives the lead screw 702 to rotate through the output shaft. The rotation of the lead screw 702 drives the L-shaped plate 704 and the mounting plate 710 above it to move until the mounting plate 710 moves to the appropriate position above the composite mold 5.

[0054] Cylinder 3 pushes the upper mold 4 downward. The downward movement of the upper mold 4 pushes the mounting plate 710 downward through spring 707 and vertical rod 706 until the nylon brush 708 located below contacts the surface of the lower mold 8 inside the composite mold 5. At this time, servo motor 713 drives the drive gear 711 to rotate through the output shaft. The rotation of the drive gear 711 drives the driven gear 712 to rotate. The rotation of the driven gear 712 drives the rotating tube 705 to rotate. The rotation of the rotating tube 705 cleans the residual material adsorbed on the inner wall of the composite mold 5, the upper mold 4 and the lower mold 8 through the hollow strip 709 and the nylon brush 708. The material residue generated by cleaning remains inside the composite mold 5.

[0055] At this time, the negative pressure fan 601 is started. The negative pressure fan 601 drives the air in the filter box 602 to flow outward, so that the inside of the filter box 602 is in a negative pressure state. Under the action of the air duct 603, cover 607, connecting hole 609 and rotating tube 705, the dust collection groove 604 opened on the outside of the hollow strip 709 generates suction to suck up the material residue in the composite mold 5. The sucked material residue is filtered by the filter screen box 605. After cleaning, the drive motor 701 rotates in reverse to reset the mounting plate 710 and carry out the subsequent pressing work. The filter screen box 605 is taken out periodically and its inside is cleaned.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
