Description

Technical Field

[0001] This utility model belongs to the field of sandblasting equipment, specifically relating to a separation device for separating iron-containing waste materials during sandblasting. Background Technology

[0002] Sandblasting is a surface treatment process whose main purpose is to remove grease, dirt, scale, rust, paint and other deposits from metal surfaces, so that the surface of metal parts reaches a certain roughness, which facilitates subsequent anti-corrosion, painting or joining processes.

[0003] The main material of sandblasting is sand particles. Sandblasting involves spraying sand particles from a sandblasting machine at high speed. The high-speed sand particles collide with the workpiece, thereby removing grease, dirt, oxide scale, rust, paint and other adhering substances from the surface of the workpiece. After the grease, dirt, oxide scale, rust and paint adhering substances from the surface of the workpiece are removed, they enter the recovery chamber of the sandblasting machine along with the sand particles.

[0004] In existing technologies, the process of recycling sand is relatively complex and the recycling cost is high. At the same time, because the cost of sand itself is low, its recycling value is not high. Many companies often directly dispose of used sand as waste, causing environmental pollution. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a separation device for separating iron-containing waste in sandblasting. This device adds a separation device to the lower end of the existing sandblasting machine, which can quickly separate metal fragments from sand particles.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a separation device for separating iron-containing waste during sandblasting, comprising a sandblasting chamber, a recovery chamber, and a slide. The sandblasting chamber includes a sandblasting chamber shell, a worktable, and a base plate. The lower end of the sandblasting chamber shell is cylindrical, and the upper end of the sandblasting chamber shell is provided with a conical sealing cover. The lower end of the sandblasting chamber shell is open, and a base plate is provided at the opening. The base plate is inverted conical, and a bottom hole is provided at the lower end of the base plate. A worktable is provided above the base plate. The recovery chamber is a square barrel with an open upper end. A first partition and a second partition are provided on the lower surface of the recovery chamber, dividing the recovery chamber into a recovery bin at the left end and a waste bin at the right end. An electromagnet is provided at the upper end of the second partition. The upper end of the slide is connected to the bottom hole, and the lower end of the slide is connected to the upper end of the recovery chamber.

[0007] The workbench is a circular flat plate that is compatible with the internal control of the sandblasting chamber. Multiple small holes are evenly distributed on the upper surface of the workbench.

[0008] The slide is inclined downwards, and a gap A is provided between the lower end of the slide and the upper end of the first partition; the upper end of the waste bin is connected to the gap A, and the electromagnet is installed at the right end of the gap A, with the electromagnet and the gap A at the same horizontal height.

[0009] The electromagnet mentioned is a controllable electromagnet.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a separation device for separating iron-containing waste in sandblasting. The device can quickly separate metal fragments from sand particles by using the magnetic attraction of an electromagnet.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The following detailed description of the specific embodiments of this utility model, in conjunction with the accompanying drawings, illustrates the following: A separation device for separating iron-containing waste during sandblasting includes a sandblasting chamber 1, a recovery chamber 2, and a chute 3. The sandblasting chamber 1 includes a sandblasting chamber shell 11, a worktable 12, and a base plate 13. The lower end of the sandblasting chamber shell 11 is cylindrical, and the upper end of the sandblasting chamber shell 11 is provided with a conical sealing cover. The lower end of the sandblasting chamber shell 11 is open, and the bottom plate 13 is provided at the opening. The bottom plate 13 is inverted conical, and the lower end of the bottom plate 13 is provided with a bottom hole 14. The worktable 12 is located above the bottom plate 13. The worktable 12 is circular. The worktable 12 is a flat plate that is compatible with the internal control of the sandblasting chamber 1. Multiple small holes are evenly distributed on the upper surface of the worktable 12. During sandblasting, the workpiece is placed on the upper surface of the worktable 12. Sand particles flow from the small holes on the upper surface of the worktable 12 into the bottom hole 14 at the lower end. The recovery chamber 2 is a square barrel with an open top. A first partition 22 and a second partition 23 are provided on the lower surface of the recovery chamber 2, dividing it into a recovery bin 24 on the left and a waste bin 25 on the right. An electromagnet 26 is provided on the upper end of the second partition 23. The slide rail... The upper end of slide 3 is connected to the bottom hole 14, and the lower end of slide 3 is connected to the upper end of the recovery chamber 2. Slide 3 slopes downwards from the bottom hole 14, and a gap A27 is provided between the lower end of slide 3 and the upper end of the first partition 22. The upper end of the waste bin 25 is connected to the gap A27, and the electromagnet 26 is installed at the right end of the gap A27, with the electromagnet 26 and the gap A27 at the same horizontal height. The electromagnet 26 is a controllable electromagnet to facilitate adjustment of its magnetic force. After the sand particles from the sandblasting process enter the bottom hole 14, they enter the slide 3. Under the action of gravity, the sand particles move from the bottom hole 14... The sand flows downwards at orifice 14. When it reaches gap A27, some sand particles fly over gap A27 due to inertia and enter the recovery bin 24, re-entering the sandblasting device. Metal fragments mixed in the sand particles change their path under the attraction of the magnetic force of electromagnet 26, pass through gap A27, and fall into waste bin 25. During the separation process, some sand particles will shrink in volume due to impact during sandblasting, forming sand dust. When these sand particles flow downwards, they will lack kinetic energy when flying over gap A27 and will also fall into waste bin 25 from gap A27, thereby improving the quality of sand particles entering the recovery bin 24.

[0018] The usage process of this utility model is as follows: First, the recovery chamber 2 is installed below the sandblasting chamber 1, and the sandblasting chamber 1 and the recovery chamber 2 are connected by the slide 3; during the sandblasting operation, the workpiece is placed on the upper surface of the workbench 12 for sandblasting; the sand particles flow from the small hole on the upper surface of the workbench 12 into the bottom hole 14 at the lower end; after the sand particles enter the bottom hole 14, they enter the slide 3, and under the action of gravity, the sand particles flow downward at an angle from the bottom hole 14. When they reach the gap A27, some of the sand particles fly across the gap A27 under the action of inertia and enter the recovery bin 24, and re-enter the sandblasting device; the metal debris mixed in the sand particles changes its path under the attraction of the magnetic force of the electromagnet 26, passes through the gap A27, and falls into the waste bin 25.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0020] The parts of this utility model not described in detail are existing technologies.
