Abstract

A hydraulic horizontal water-retaining moulding device for mixed materials was designed and optimized. The effect of compression process parameters of the mixture of straw and cow dung on the effect of water retention moulding was analysed through experiment. The suitable value range and critical value of process parameters were obtained. The main power and structural parameters of the hydraulic system in the mixture compression unit were designed and calculated. Appropriate hydraulic and control components were selected. A test prototype of the hydraulic horizontal mixed material compressor machine was manufactured. Through the method of combination experiment and response surface optimization, the optimal combination of working parameters of the hydraulic horizontal water-retaining moulding device was obtained and verified. The dimensional stability of small-scale compost blocks made by the compressor could reach 84.71% under the condition of 250 mm/min for the compression speed, 55 kg for the feed amount and 200 s for the holding time.
