This invention belongs to the field of concrete building materials technology, and discloses a fiber-reinforced concrete segment suitable for dual control of micro-cracks and macro-cracks, and its preparation method. The fiber-reinforced concrete segment comprises cement-based concrete and crack-resistant fibers and structural fibers compositely added to the cement-based concrete. The crack-resistant fibers are fine steel fibers with a diameter of 0.15-0.25 mm and a length of 10-15 mm; the structural fibers are coarse polypropylene fibers with a diameter of 0.8-1.2 mm and a length of 40-60 mm; the volume fraction of the crack-resistant fibers is 0.5%-0.8%; and the volume fraction of the structural fibers is 0.5%-0.9%. The fiber-reinforced concrete segment provided by this invention can achieve continuous crack control, synergistic effect, and better economic efficiency.

The utility model provides a spraying granulation sulfenyl compound fertilizer granulation device, which comprises a mounting rack and a particle screening barrel, the particle screening barrel fixedly penetrates through the top of the mounting rack, a screening frame is fixedly mounted at the top of the inner wall of the particle screening barrel, and a screen is fixedly mounted at the bottom of the screening frame. Compared with the prior art, the device has the following beneficial effects that the caking and scattering assembly is arranged below the discharging pipe, when caking particles are left in the screening frame, the electromagnetic valve on the discharging pipe is opened, the caking particles can be discharged, at the moment, the caking and scattering assembly is started, and the material receiving spoon is arranged towards the spoon opening of the baffle due to the unique semi-spherical design; the baffle plate is arranged on the base, so that the baffle plate can well bear and hit agglomerated particles by means of impact force generated by circular motion, and the scattered particles slide down through the inclined surface of the baffle plate, thereby effectively solving the agglomeration problem in the screening process of fertilizer particles, ensuring the product quality and the particle uniformity, and improving the competitiveness of the product in the market.

The utility model relates to a discharging device technical field, specifically disclose a kind of anti -blocking discharging device. Among them, including upper pipeline structure, lower pipeline structure, heating structure being arranged on the upper pipeline structure and the lower pipeline structure, filter structure being arranged between the upper pipeline structure and the lower pipeline structure and the broken material structure being arranged above the filter structure, the heating structure is used to heat the material liquid in the upper pipeline structure and the lower pipeline structure, the agglomerate in material liquid can be intercepted by the filter structure, the broken material structure can break agglomerate. The utility model effectively solves the problem of blocking and agglomeration in the adhesive discharging process, improves the discharging efficiency and product quality.
