Description

Dry process producing extruding forming machine for gypsum lath and building block

Technical Field

The utility model relates to a gypsum slat and building block preparation system, concretely relates to gypsum slat and building block dry process production extrusion moulding machine.

Background

Gypsum, the main component of which is calcium sulfate, includes natural gypsum and industrial gypsum. The industrial gypsum, also called industrial byproduct gypsum, is a byproduct in some industrial production processes, mainly comprises two types, namely phosphogypsum and desulfurized gypsum, wherein the phosphogypsum accounts for more than half of the industrial byproduct gypsum. At present, the accumulated quantity of industrial by-product gypsum in China exceeds 3 hundred million tons, wherein the phosphogypsum reaches more than 2 hundred million tons. The industrial by-product gypsum is piled up in large quantity, which not only occupies land, but also wastes resources, and the contained acidity and other harmful substances easily cause pollution to the surrounding environment, thus becoming an important factor restricting the sustainable development of phosphate fertilizer enterprises in China. The efficiency of developing and recycling the industrial byproduct gypsum is low at present, and the comprehensive utilization rate is only about 38%; therefore, the development of a secondary utilization technology of industrial by-product gypsum is still a subject of considerable research.

The industrial by-product gypsum product is a gypsum block, a gypsum brick, a gypsum board, a gypsum large wallboard, a plastering gypsum, a gypsum paper and other products which are prepared by taking industrial by-product gypsum as a main material. Because the industrial byproduct waste can be recycled, the industrial byproduct gypsum product has lower production cost, better economic value and great significance in environmental protection, and has wider development and utilization prospect. Particularly, gypsum boards (also called gypsum laths) and gypsum blocks are widely applied to buildings, and the existing gypsum laths and blocks are usually produced by adding water into gypsum, stirring the gypsum into slurry, and then casting the slurry, which is called wet production or slurry production. The product produced by the production method needs to be dried after being formed, the process is complex, the energy consumption is high, the energy-saving effect is poor, and the obtained product has low density and poor quality.

The inventor has previously applied for a production process of a full dry method desulfurized gypsum building material product of CN200710092850, and discloses that water with a crystal water ratio is directly added into anhydrous gypsum and semi-hydrated gypsum, and the anhydrous gypsum and the semi-hydrated gypsum are processed and formed in a high-pressure mode. Compared with wet production, the process is simpler, does not need drying, and the prepared product has higher density and better quality. But also has the defects of higher requirements on production equipment, more complex process and higher difficulty in controlling the quality of products.

CN201711112428 discloses a gypsum board and a preparation method thereof, and the gypsum board is produced by adopting an extrusion method in the patent, so that the process is simple. However, the gypsum board obtained by the method is obtained by adopting gypsum powder, various auxiliary materials and resin adhesive, and is bonded by the resin to provide bonding force, so that the board has low integral strength and poor quality.

In addition, CN200610127778 discloses a method for producing gypsum building products by using extrusion process, in which the gypsum product is produced by adding water to semi-hydrated gypsum and then extruding by means of an extruder, and the process is simpler. However, the following drawbacks still exist in this patent: 1 the process method has complex raw material formula components, and in addition to the gypsum powder, filler powder and various additives are added, so that the process complexity is increased, and the production cost is higher. 2 the process formula is added with the filler powder such as fly ash, fine sand and the like, and the plasticizer is also added as a setting material, if water is added in advance for mixing and stirring, the setting reaction is easy to generate and the process fluidity is influenced, so the process adds the mixing water at the position of an extrusion opening, but the water is difficult to be fully mixed and reacted with the semi-hydrated gypsum to generate the dihydrate gypsum, and the product quality is greatly reduced. 3 the process does not disclose the specific structure of the extruder and the device for conveying and cutting the parts, and has poor practicability.

In summary, how to provide a dry method gypsum lath production technology with simple raw materials, simple process, higher product quality and good feasibility becomes a problem to be considered and solved by the technical personnel in the field.

Wherein, still be provided with two at least stack belts 42 on the stack platform, stack belt 42 perpendicular to rollgang setting and stack belt upper surface form the stack holding surface, leave the space that supplies fork frame male between the support frame below the stack holding surface between stack belt 42, the band pulley of stack belt 42 one end is installed on same band pulley axle 43, and band pulley axle 43 and a stack belt control are with step motor 44 transmission connection.

Therefore, the stepping motor for controlling the stacking belt can control the stacking belt to rotate discontinuously, so that the stacking support surface of the stacking belt can translate gradually, and the sequential arrangement and stacking of the slats on the stacking belt are completed. When the stacking belts are fully stacked with the full row of slats, the forks of a forklift can be inserted into the lower gap between the stacking belts to transfer and stack the full row of slats. Therefore, the stacking belt can be matched with the turnover shaft to realize continuous stacking assembly line operation of the laths, and automation of operation is realized.

Wherein, the belt wheel of the stacking belt 42 far away from one end of the conveying roller way is arranged on a belt wheel shaft 43, the belt wheel shaft is in transmission connection with a stepping motor 44 for controlling the stacking belt through a transmission belt, and the stepping motor 44 for controlling the stacking belt is fixedly arranged on a support frame below the stacking belt.

The structural layout is more reasonable and reliable.
