However, after the brick products with large specifications are dried by the conveying device, bending deformation always occurs, and the qualification rate is difficult to meet the requirement of batch production. After multiple observations and tests of the applicant, the problem is finally found that the large-size brick product has a large bottom area and a large contact area with a conveying device, and the friction force between the contact part and the bottom of the brick can influence the shrinkage of the bottom of the brick product and also influence the evaporation of water at the bottom of the brick. Due to the large difference of the shrinkage rates of all parts of the whole brick, the product deforms and bends after drying.
Adopt the utility model discloses a drying system changes conveyer into multiunit drive disk assembly and meets in proper order and form, including many chains that set up side by side in every drive disk assembly, and the brick goods are placed on the chain that sets up side by side, adopt such structure, and the bottom of brick goods and conveyer's area of contact significantly reduces, is favorable to the evaporation of bottom moisture, reduces the influence of frictional resistance to the shrink.
In a further improvement, the chains of the two adjacent groups of transmission parts are arranged in a staggered manner. Because the chains of the adjacent transmission component groups are arranged in a staggered manner, the bottom of the brick is prevented from being always in contact with the contact part of the conveying device at the same position in the drying and moving process, and the shrinkage consistency of all parts at the bottom is improved.
In a further improvement, two adjacent groups of transmission parts share one transmission shaft. Because the conveying device consists of a plurality of groups of transmission parts, the transmission parts which are connected in pairs share one transmission shaft, the seamless butt joint of chains between every two adjacent transmission parts is ensured, and the stable conveying in the conveying process is realized.
In consideration of the bearing of large-size products, in order to avoid the sinking of the chains, at least one supporting plate frame for supporting the chains can be arranged in each group of transmission parts.
The improved chain wheel is further improved by comprising a power part, and the transmission part drives the transmission shaft to drive the chain wheel and the chain to rotate through the power part.
Alternatively, a chain belt may be used as the chain.
The improved transmission mechanism is further improved by comprising a rack, transmission shafts of the transmission parts are arranged on the rack, transmission is stable, each group of transmission parts can be integrated through the rack, and the assembly, disassembly and maintenance are more convenient.
In a further improvement, the drying device also comprises a drying part, the drying part is arranged at the side part of the transmission part, and the drying part is connected with the roasting kiln through a pipeline. The bottom and/or upper air supply drying in the prior art is not beneficial to the drying of large-size products, the lateral air supply is realized, the drying uniformity is good, and in addition, the waste heat of the roasting kiln is utilized as a drying heat source, so that the energy is saved and the environment is protected.
In a further improvement, the feeding end at the front part of the transmission component group is connected with a green brick conveying belt, and the discharging end at the rear part is connected with the roasting kiln through a transmission device.
