Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, and in particular to an anti-splash shot blasting machine for civil engineering projects. Background Technology
[0002] Shot blasting machines are mainly used in civil engineering to treat metal sheets to improve their surface quality and corrosion resistance. Specifically, shot blasting machines clean and strengthen metal surfaces by spraying high-speed shot, removing rust, scale, and dirt, increasing surface roughness, and thus improving coating adhesion and corrosion resistance. However, in actual operation, it has been found that because the shot is accelerated and ejected under centrifugal force, forming a fan-shaped jet that impacts the working plane, some shot directly impacts the bottom collection box during the rebound, especially the blades of the screw feeder, easily damaging the screw feeder equipment, increasing maintenance costs, and shortening its service life. Based on this, this utility model proposes an anti-splash shot blasting machine for civil engineering structures. Utility Model Content
[0003] The purpose of this invention is to provide a shot blasting machine for civil engineering projects that prevents splashing, thereby solving the problems mentioned above.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses an anti-splash shot blasting machine for civil engineering, comprising a housing, an inlet at the upper end of the housing, several shot blasters on the side walls, and a collection box at the bottom; a shot box at the top of the housing, and the shot box and the collection box are connected by a shot lifting device; a material plate is provided on the inner side wall of the collection box at the top position, the material plate has a bent structure, and several through holes are equally spaced in the grooves of the material plate, the diameter of the through holes being larger than the diameter of the shot.
[0006] Furthermore, mounting plates two are symmetrically arranged on the inner sidewall of the box, and mounting plates one that cooperate with mounting plates two are symmetrically arranged on both sides of the material plate.
[0007] Furthermore, the bent structure of the material plate is distributed in a wave-like pattern.
[0008] Furthermore, a spiral feeder is provided at the bottom of the collection box. One end of the spiral feeder is rotatably disposed inside the collection box, and the other end extends out of the collection box and is connected to a collecting device. The collecting device is located at the bottom of the shot lifting device. The end of the collecting device away from the collection box is fixedly connected to a rotating shaft, and the rotating shaft extends out of the shot lifting device and is connected to a motor.
[0009] Furthermore, the collecting device is spherically distributed, and the inside of the collecting device is hollow. Several slots are opened on the circumference of the collecting device for the projectile to exit.
[0010] Furthermore, a downward-cleaning guide plate is provided on the bottom surface of the shot lifting device, located below the collecting device.
[0011] Furthermore, both the housing and the projectile lifting device are connected to a dust collector.
[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0013] This utility model of an anti-splash shot blasting machine for civil engineering uses a material plate to block the accelerating shot, preventing it from rebounding directly onto the bottom spiral feeding device. The bent structure of the material plate also helps to slow down the rebound and collects the shot, which falls through through holes into a collection box below for reuse. In summary, this utility model of an anti-splash shot blasting machine for civil engineering prevents shot from splashing, allows the shot to fall with a buffer, extends the equipment's service life, and saves on maintenance costs.

[0020] like Figure 1-4As shown, a shot blasting machine for civil engineering projects includes a housing 1. A feed inlet 3 is installed at the upper end of the housing 1, several shot blasters 2 are installed on the side walls, and a collection box 7 is installed at the bottom. A shot box 4 is installed on the top of the housing 1, and the shot box 4 and the collection box 7 are connected by a shot lifting device 6. The shot box 4 and the shot blasters 2 are connected by pipes. A material plate 11 is installed on the inner side wall of the collection box 7 at the top position. The material plate 11 has a bent structure, and several through holes 12 are evenly spaced in the grooves on the material plate 11. The diameter of the through holes 12 is larger than the diameter of the shot. The bent structure of the material plate 11 is wave-shaped. When the shot falls onto the material plate 11, it falls into the grooves and then through the through holes 12 into the collection box 7 below. This buffers the force of the shot rebounding directly onto the collection box 7, thereby protecting the equipment inside the collection box 7, reducing maintenance costs, and extending the service life of the equipment.
[0021] Mounting plates 15 are symmetrically installed on the inner side wall of the box 1, and mounting plates 14 that cooperate with mounting plates 15 are symmetrically installed on both sides of the material plate 11, so as to facilitate the disassembly of the material plate 11.
[0022] A spiral feeder 8 is installed at the bottom of the collection box 7. One end of the spiral feeder 8 is rotatably installed inside the collection box 7, and the other end extends out of the collection box 7 and is connected to the collecting device 9. The collecting device 9 is located at the bottom of the shot lifting device 6. The collecting device 9 is spherically distributed and has a hollow internal structure. Several slots are opened on the circumference of the collecting device 9 for the shot to exit. The end of the collecting device 9 away from the collection box 7 is fixedly connected to a rotating shaft 10. The rotating shaft 10 extends out of the shot lifting device 6 and is connected to a motor. When the motor starts, the spiral feeder 8 carries the shot into the internal cavity of the collecting device 9. During the rotation of the collecting device 9, the shot inside falls from the slots into the bottom of the shot lifting device 6 below and is transported to the shot box 4 at the top.
[0023] The bottom surface of the shot lifting device 6 is equipped with a downward cleaning guide plate 13 located below the collecting device 9 to prevent shot from accumulating in dead corners.
[0024] The housing 1 and the projectile lifting device 6 are both connected to the dust collector 5. The dust collector 5 mainly processes the dust and impurities that come down from the impact of the projectile. In this embodiment, the dust collector 5 adopts a cyclone dust collector.
[0025] The operation process of this utility model is as follows:
[0026] First, the shot enters the shot blaster 2 from the shot box 4. Under the centrifugal force and wind force generated by the high-speed rotation of the shot blasting wheel, it is accelerated and thrown out, forming a fan-shaped jet that impacts the working surface. Then, the shot bounces and falls onto the material plate 11 below to avoid splashing. It then falls through the through hole 12 on the material plate 11 into the collection box 7 below. Dust and impurities pass through the bounce chamber and enter the collection box 7 together. Finally, the shot in the collection box 7 is conveyed to the collecting device 9 by the screw feeder 8. From the collecting device 9, it falls into the bottom of the shot lifting device 6 below and is conveyed to the shot box 4 at the top for recycling. The dust and impurities are treated by the dust collector 5.
[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
