The device is characterized in that sand and stone materials for spraying concrete are loaded into a conical hopper through a loader or a forklift, a vibrator is electrified to generate vibration, the downward flow speed of the sand and stone materials is accelerated, the sand and stone materials flow onto a wire mesh filter screen below the hopper, and the sand and stone materials finer than meshes on the wire mesh filter screen fall into a mixer hopper below through the meshes; while the stone material larger than the mesh overflows from one side of the filter screen. Greatly reducing the labor intensity, shortening the screening time, reducing the cost and improving the efficiency. Moreover, the device is formed by welding steel pipes and deformed steel bars, the structure is firm, the material loading is stable, and the lifting is convenient and safe.

Description

Filter for spraying concrete sand and stone

Technical Field

The utility model relates to a solid filtering machine, especially jet concrete gravel and sand filter equipment.

Background

The sand and stone individuals for spraying the concrete cannot be too large and cannot enter the concrete sprayer pipe, or the sand and stone individuals for spraying the concrete cannot be too large and heavy and cannot reach the spraying requirement due to insufficient spraying force. Therefore, shotcrete gravel is screened to remove oversized stones. The screening of present injection concrete grit all is artifical shovel grit to the wire netting filters the screening, and the grit after the screening needs the manual work to cooperate the shovel to enter the mixer, and intensity of labour is big, long time, with high costs and inefficiency, and moreover, the grit after the screening still needs the manual work to cooperate the shovel to enter the mixer, mixes into injection concrete together with other stirring materials. The requirements of large working face, high workload and long construction period are difficult to meet.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a little, the time of intensity of labour is short, with low costs and efficient injection concrete grit filter equipment.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a spray concrete grit filter equipment, includes support and wire netting filter sieve, its characterized in that still includes:

the conical hopper is arranged at the upper end of the bracket and above the wire mesh filter screen and is large at the top and small at the bottom;

a vibrator fixed on one side surface of the conical hopper;

and a sprayed concrete mixer is arranged in the support below the wire mesh filter screen.

The sand and stone filter device for spraying concrete with the structure has the advantages that sand and stone materials for spraying concrete are loaded into the conical hopper through the loader or the forklift, the vibrator is electrified to generate vibration to accelerate the downward flow speed of the sand and stone materials, the sand and stone materials flow onto the wire mesh filter screen below the hopper, and as the vibrator, the conical hopper and the wire mesh filter screen are all fixed on the same support, and the conical hopper and the wire mesh filter screen vibrate when the vibrator generates vibration, the sand and stone materials finer than meshes on the wire mesh filter screen fall into the hopper of the mixer below through the meshes; and the stones larger than the meshes overflow from one side of the filter screen or are easily pulled out by hand with a tool. Greatly reducing the labor intensity, shortening the screening time, reducing the cost and improving the efficiency. Moreover, the device is formed by welding steel pipes and deformed steel bars, the structure is firm, the material loading is stable, and the lifting is convenient and safe.

Drawings

Fig. 1 is a schematic view of the present invention;

in figure 1, a stirrer 1, a wire mesh filter screen 2, a vertical steel pipe 3, a vibrator 4, a conical hopper 5, a hopper supporting rod 6 and a horizontal steel pipe 7.

Detailed Description

Fig. 1 shows, is the structure diagram of the utility model, and it can be known from the figure, the utility model discloses a wire netting filter sieve 2, toper hopper 5 and by four perpendicular steel pipes 3, four spinal branchs pole 6 and four horizontal steel pipe 7 fixed connection constitutions's support. The four vertical steel pipes 3 and the four transverse steel pipes 7 form a square column shape, and two ends of the four transverse steel pipes 7 are fixedly connected with the vertical steel pipes 3 respectively to form a square frame; the upper ends of the four vertical steel pipes 3 are fixedly connected with the upper four corners of the conical hopper 5, and the lower four corners of the conical hopper 5 are respectively and fixedly connected with the four vertical steel pipes 3 through four hopper supporting rods 6; the wire mesh filter screen 2 is arranged in a square frame formed by four transverse steel pipes 7, and the periphery of the wire mesh filter screen is fixedly connected with the four transverse steel pipes 7 on the four sides through ropes. The vibrator 4 is fixedly arranged in the middle of one side of the conical hopper 5.

The utility model discloses a theory of operation does:

the vibrator 4 is electrified to generate vibration, gravel materials for spraying concrete are loaded into the conical hopper 5 through a loader or a forklift, the downward flow speed of the gravel materials of the conical hopper 5 is accelerated due to the vibration of the vibrator, the gravel materials flow onto the wire mesh filter screen 2 below the conical hopper 5, and as the vibrator 4, the conical hopper 5 and the wire mesh filter screen 2 are all fixed on the same support, and the conical hopper 5 and the wire mesh filter screen 2 vibrate when the vibrator 4 generates vibration, the gravel finer than meshes on the wire mesh filter screen 2 falls into the hopper of the stirring machine 1 below through the meshes; and the sand stones larger than the meshes overflow from one side of the wire mesh filter screen 2 or are easily pulled out by hand with a tool. The sand and stone in the hopper of the mixer 1 are evenly mixed with other materials and then are sent into a spraying machine, and the mixed sprayed concrete is sprayed to a sprayed surface by pressure gas through a material conveying pipe and a spray head. The mesh size or mesh number of the wire mesh filter screen 2 is selected by one skilled in the art according to the prior art and actual needs.

The utility model discloses through research and development, experiment and simulation to a plurality of engineering use have been passed through, respond well.
