Problems solved by technology

[0002] In the construction process of construction projects, it is necessary to fine-screen the sand transported to the construction site so that the sand meets the requirements of construction materials. The traditional sand screening device uses a vibrating screen to screen the sand, which cannot be well screened. Clean up the compacted sand, and the wet sand is easy to make the sand sticky, block the screen, and affect the screening efficiency

Embodiment 1

[0023] see Figure 1-5 , in an embodiment of the present invention, a coarse sand screening and drying device for construction engineering, comprising a sieve box 1 and a sieve cylinder 2; hole, and the screen cylinder 2 is a hollow conical cylinder arranged horizontally, which is convenient for sand and waste residue to move with the rotation of the screen cylinder 2; A gear ring 10 is fixed on the sleeve, and the upper end of the gear ring 10 is engaged with a transmission gear 11. The transmission gear 11 is fixedly connected to a transmission shaft 12. The transmission shaft 12 extends to the outside of the screen box 1 and is rotationally connected with the screen box 1. The transmission shaft 12 passes through the The first transmission belt 13 is connected with a second motor 14, and the second motor 14 is fixedly connected with the top plate of the screen box 1 by means of bolts; during operation, the second motor 14 drives the transmission gear 11 to rotate through th...

Embodiment 2

[0029] The difference between this embodiment and Embodiment 1 is: in order to improve the drying effect; the outer side of the drum 17 is provided with rolling rollers 15 distributed in a circle, and the rolling rollers 15 are in contact with the inner wall of the screen cylinder 2 and are slidably connected; Roller 15 is rotatably connected with roller frame 16, and roller frame 16 is fixedly connected with drum 17, and drum 17 is connected with transmission shaft 13 through second transmission belt 18; during operation, transmission shaft 13 drives drum 17 through second transmission belt 18. Rotating, the drum 17 drives the rolling roller 15 to make a circular motion in the screen drum 2 through the roller frame 16, and the rolling roller 15 cooperates with the inner wall of the screen drum 2 to crush and crush the sand; at the same time, the drum 17 drives the nozzle 19 Rotate, so that the hot air sprayed from the nozzle 19 blows the inner wall of the sieve cylinder 2 comp...

Abstract

The invention discloses a coarse sand screening and drying device for constructional engineering. The coarse sand screening and drying device comprises a screen box and a screen drum. The rotary screen drum is nested in the screen box, and a feeding pipe is arranged at the left side of the screen drum; a spiral feeding roller is arranged in the feeding pipe, the tail end of the feeding pipe is communicated with a scattering cover, and an impeller plate is nested in the scattering cover; a rotary drum is arranged in the screen drum, and spray heads distributed at equal intervals are arranged onthe rotary drum. By arranging the spiral feeding roller, the spiral feeding cover and the impeller plate, sand is thrown and dispersed while being evenly fed, sand blocks are impacted and crushed, the sand is fully dispersed, and follow-up drying and screening are facilitated; through the arrangement of the rotary screen drum, a grinding roller, the rotary drum and the spray heads, sand blocks are further ground and crushed, meanwhile, the spray heads are driven to blow in the circumferential direction, the drying uniformity and efficiency are improved, and through cooperation with the grinding roller, sand block crushing is accelerated, and the screening efficiency is further improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a coarse sand screening and drying device for construction engineering. Background technique [0002] In the construction process of construction projects, it is necessary to fine-screen the sand transported to the construction site so that the sand meets the requirements of construction materials. The traditional sand screening device uses a vibrating screen to screen the sand, which cannot be well screened. Clean up the compacted sand, and the wet sand will easily make the sand sticky, block the screen, and affect the screening efficiency. Contents of the invention [0003] The object of the present invention is to provide a coarse sand screening and drying device for construction engineering, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical sol...
