Description

Technical Field

[0001] This utility model relates to the field of metal cleaning technology, and in particular to a metal surface cleaning device. Background Technology

[0002] Cleaning metal surfaces is a crucial step in metal processing and surface treatment. It removes dirt, oxide layers, rust, and other contaminants from the workpiece surface, while also roughening the surface, increasing adhesion, and providing a good foundation for subsequent coating, plating, and other processes.

[0003] Patent CN215318094U discloses a sandblasting machine, which includes a sandblasting machine housing, an observation window, and an operating port. When sandblasting a workpiece, the worker inserts both hands through the operating port into operating gloves, holding the spray gun in one hand and picking up or moving the workpiece with the other, thereby performing sandblasting treatment on the workpiece. Existing sandblasting machines have the following shortcomings:

[0004] First, the lack of an air intake channel can easily lead to a negative pressure state inside the sandblasting machine chamber. This increases the impact of sand particles on the chamber walls during the recycling process after cleaning, exacerbating equipment wear and shortening its service life.

[0005] Secondly, the compressed air is controlled by only one solenoid valve. Over time, the wear and tear on the solenoid valve is aggravated. Once the solenoid valve fails, it will seriously affect the progress of the entire sandblasting process, increase the cost of downtime maintenance, and reduce the cleaning efficiency of the metal surface. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a metal surface cleaning device.

[0007] Therefore, this utility model provides a metal surface cleaning device, including a sandblasting machine housing, an observation window, and an operating hole. The observation window is provided on the front side of the sandblasting machine housing, and two operating holes are provided on the sandblasting machine housing below the observation window. A material discharge bin is connected to the bottom of the sandblasting machine housing, and air inlets are provided on both sides of the sandblasting machine housing. An air intake channel is formed between the two air inlets. A plurality of toothed air holes arranged in an array are provided at the bottom of the air intake channel. A plurality of high-pressure pipes are connected inside the sandblasting machine housing, and each high-pressure pipe is controlled by a corresponding control valve.

[0008] Preferably, a baffle is rotatably installed at the air inlet, and the baffle is flipped inward.

[0009] Preferably, a limiting piece for defining the position of the baffle is fixedly installed at the bottom of the air inlet.

[0010] Preferably, the sandblasting machine housing is equipped with multiple switches, which are used to control the opening and closing of the control valve.

[0011] Preferably, the sandblasting machine housing is fixedly mounted on a support frame, and an air vent pipe is fixedly mounted on the support frame. The air vent pipe is connected to multiple control valves.

[0012] Preferably, a partition is fixedly installed at the bottom of the sandblasting machine box, and multiple spray nozzles connected to the high-pressure pipe are opened around the partition. The partition is also provided with multiple evenly distributed array of leakage holes, which are connected to the discharge hopper.

[0013] Preferably, the sandblasting machine housing is provided with an exhaust port that is connected to the dust removal fan.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a metal surface cleaning device, which has the following beneficial effects.

[0015] (1) When the sand particles are recovered into the discharge bin through the vent, the outside gas enters through the air intake channel, which changes the negative pressure state inside the sandblasting machine box, reduces the impact of the sand particles on the machine box wall, reduces the wear of the equipment, and extends the service life of the equipment.

[0016] (2) Multiple control valves are used to connect multiple high-pressure pipes to clean the surface of the workpiece. This decentralized control means that a single control valve failure will not cause a shutdown or affect the progress of sandblasting and cleaning, thus improving the efficiency of cleaning the surface of metal workpieces. At the same time, multiple control valves can also achieve fine control to meet the cleaning needs of workpieces of different materials.

[0017] (3) The bottom of the air intake channel is arranged in an array of teeth, which can make the gas diffuse more evenly into the sandblasting machine box, making the air pressure in the sandblasting machine box more stable.

[0018] (4) The baffle can guide the flow direction of the gas, allowing it to enter the sandblasting machine box more smoothly. It can also automatically reset when no air is being introduced, blocking the splashes or impurities generated during the sandblasting process. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Example:

[0027] like Figures 1-5 As shown, this utility model provides a metal surface cleaning device, including a sandblasting machine housing 1, an observation window 2, and an operation port 3. The observation window 2 is provided at the front door 19 of the sandblasting machine housing 1. The observation window 2 is made of transparent tempered laminated glass. Two operation ports 3 are provided on the sandblasting machine housing 1 below the observation window 2. An operating glove is connected to the inside of the operation port 3. A funnel-shaped discharge bin 4 is connected to the bottom of the sandblasting machine housing 1. Air inlets 5 are provided at the top of both sides of the sandblasting machine housing 1. An air intake channel 6 is formed between the two air inlets 5. Multiple toothed air holes 7 arranged in an array are provided at the bottom of the air intake channel 6 to make the gas diffusion more uniform and avoid sand particles hitting the machine housing wall and causing damage under negative pressure. Multiple high-pressure pipes 8 are connected inside the sandblasting machine housing 1. Each high-pressure pipe 8 is controlled by a corresponding control valve 9 to avoid the phenomenon of machine shutdown due to failure when only a single control valve 9 is working.

[0028] Furthermore, a baffle plate 10 is rotatably installed at the air inlet 5. The baffle plate 10 flips inward to effectively guide the flow direction of the external gas, allowing the gas to enter the sandblasting machine box 1 more smoothly. At the same time, it can automatically reset when no air is being introduced to block the splashes or impurities generated during the sandblasting process.

[0029] Furthermore, a limiting piece 11 is fixedly installed at the bottom of the air inlet 5 to limit the position of the baffle 10, so as to prevent the baffle 10 from rotating too much and failing to play a blocking role.

[0030] Furthermore, the sandblasting machine housing 1 is equipped with multiple switches 12, which are used to control the opening and closing of the control valve 9. Each switch 12 corresponds to the opening and closing of one control valve 9, and the control valve 9 is a solenoid valve.

[0031] Furthermore, the sandblasting machine housing 1 is fixedly mounted on the support frame 13, and an air pipe 14 is fixedly mounted on the support frame 13. The air pipe 14 is connected to a plurality of control valves 9.

[0032] The ventilation pipe 14 is connected to the air compressor, so that compressed air enters the high-pressure pipe 8 through the solenoid valve and is sprayed out by the sandblasting gun to clean the metal surface.

[0033] Furthermore, a partition 15 is fixedly installed at the bottom of the sandblasting machine box 1. Multiple spray nozzles 16 connected to the high-pressure pipe 8 are opened around the partition 15. The spray nozzles 16 are connected to the sandblasting gun. Multiple evenly distributed perforated holes 17 are also opened on the partition 15. The perforated holes 17 are connected to the discharge bin 4.

[0034] Furthermore, the sandblasting machine housing 1 is provided with an exhaust port 18 connected to the dust removal fan, which can quickly and effectively remove dust from the sandblasting machine housing 1 and avoid environmental pollution.

[0035] Furthermore, the bottom of the discharge bin 4 is connected to an external device, which can promptly recover materials to avoid excessive accumulation and blockage, thus achieving recycling.

[0036] Furthermore, the sand particles are quartz sand particles.

[0037] The working principle is as follows:

[0038] Place the metal workpiece to be cleaned on the partition 15 inside the sandblasting machine housing 1, turn on the corresponding switch 12 to control the corresponding control valve 9 to open, and insert the worker's hands through the operation hole 3 into the operating gloves. Hold the sandblasting gun in one hand and pick up or move the workpiece with the other hand. The sand particles in the sandblasting gun are sucked from the feeding bin 4. The sucked sand particles are impacted at high speed by the compressed air, cleaning the surface of the metal workpiece.

[0039] After cleaning, if there is still a negative pressure tendency inside the sandblasting machine box 1, it will create a pressure difference with the outside atmospheric pressure. This pressure difference will guide outside air to enter from the air inlet 5, push the baffle 10 to flip inward, replenish the gas in the box, balance the air pressure in the box, and the sand particles inside the sandblasting machine box 1 will fall and re-enter the discharge bin 4 through the leakage hole 17 for recycling.
