Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment, in particular to a high-efficiency metal surface treatment sandblasting machine. Background Art

[0002] A sandblaster is a device used for metal surface treatment. It modifies the surface of a workpiece by ejecting abrasive material at high speed. The machine's operating principle is to use compressed air as a power source to form a high-speed jet beam, which sprays the abrasive material onto the workpiece surface at high speed. This removes rust, old paint, dirt, and other surface impurities, while achieving a certain degree of cleanliness and varying degrees of roughness, which helps improve the adhesion of subsequent coatings.

[0003] The utility model patent with reference to the authorized patent number CN220373028U provides a metal surface treatment sandblasting equipment, including a transport frame, a shell is provided in the middle of the transport frame, and sandblasting guns are provided at the inner two ends of the shell and above the transport frame, and a rotating rod is provided in the middle of the top of the transport frame and inside the shell, and adjustment rods are provided at both ends of the rotating rod. By installing the sandblasting gun at the inner two ends of the shell, when the workpiece is transported by the transport frame, the rotating rod is driven by the telescopic rod to move up to a reversible position, and the rotating rod is driven by the motor to rotate 180 degrees, so that the workpiece is located above the second support plate, and the rotating rod is driven down by the telescopic rod to make the support bar of the second support plate contact with the transport frame, so that the workpiece completes 180 degrees, and the sandblasting gun is used to sandblast the top and bottom ends of the workpiece, avoiding the need for multiple sandblasting to complete sandblasting of the workpiece, thereby improving the sandblasting efficiency of the workpiece.

[0004] During use, it was found that the above-mentioned patent required continuous supply of sand to the sandblasting gun when sandblasting the workpiece, and was unable to recycle the waste sand after sandblasting, resulting in a waste of resources. The sand used for sandblasting has the advantage of being easy to recycle. Strengthening the recycling of waste materials can effectively reduce the waste of resources. For this reason, we proposed a high-efficiency metal surface treatment sandblasting machine. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-efficiency metal surface treatment sandblasting machine.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The sand material after sandblasting falls back to the bottom of the sand blasting tank and is filtered by the multiple groups of filter components in the filter box under the action of the feed pump to remove impurities. At the same time, the filter screen in the filter screen adopts a magnetic coating paint coating surface, so that the metal mesh not only filters out large-particle impurities but also adsorbs metal powder impurities mixed in the sand material, so that the sand material passing through the filter screen is of high purity and has the conditions for recycling again. The filtered sand material is transported by the feed pump and returned to the hopper through the upper connecting pipe. In the whole process, the sand material completes the self-circulation process, which reduces the waste of sand material.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A high-efficiency metal surface treatment sandblasting machine includes a sandblasting pot 1, a curved door 2 is rotatably installed on the side of the sandblasting pot 1, a support frame is provided at the bottom of the sandblasting pot 1, a support plate 3 is fixedly installed on the side of the sandblasting pot 1, a filter box 4 is fixedly installed at the bottom of the support plate 3, a lower connecting pipe 5 is installed between the filter box 4 and the bottom of the sandblasting pot 1, a feed pump 6 is fixedly installed on the upper side of the support plate 3, the filter box 4 is connected to the working chamber of the feed pump 6, and a silo 7 is fixedly installed on the upper end of the sandblasting pot 1 An upper connecting pipe 8 is installed between the silo 7 and the feed pump 6, a feeding port 701 is fixedly installed on the silo 7, and a sealing buckle cover 702 is screwed on the feeding port 701. A sandblasting pump 9 is arranged inside the silo 7, and a sandblasting pipe 10 is connected to the output end of the sandblasting pump 9. The sandblasting pipe 10 extends to the inside of the sandblasting tank 1 and a high-pressure nozzle 11 is installed at the lower end of the sandblasting pipe 10. A pad 12 is provided directly below the high-pressure nozzle 11, and a filter assembly 13 is provided inside the filter box 4.

[0023] In this embodiment, the filter assembly 13 includes a slide groove 14, a frame 15 is slidably connected to the inside of the slide groove 14, and a filter screen 16 is fixedly connected to the inside of the frame 15. The filter assembly 13 is provided with three groups, and the mesh size of the filter screen 16 gradually decreases from the bottom to the top, and the filter screen 16 is evenly coated with magnetic coating paint.

[0024] Through the above structure, when under the action of the feed pump 6, the sand material falling on the bottom of the sandblasting pot 1 enters the filter box 4 for filtration through the lower connecting pipe 5. Since the mesh size of the filter screen 16 decreases step by step from the bottom to the top, the large-particle impurities mixed in the sand material are gradually filtered out under the step-by-step filtration of the three-pole mesh. At the same time, the filter screen 16 is evenly coated with magnetic coating paint, and the filter screen 16 has magnetism to adsorb the iron-nickel metal powder mixed in the sand material, so that the purity of the sand material passing through the filter component 13 is guaranteed, and the requirements for reuse are met.

[0025] In this embodiment, a sealing plate 401 is provided on the filter box 4 , a sealing gasket 17 is provided between the sealing plate 401 and the filter assembly 13 , and the sealing plate 401 is screwed onto the filter box 4 by bolts.

[0026] Through the above structure, the sealing gasket 17 arranged between the sealing plate 401 and the filter assembly 13 ensures the fit between the filter assembly 13 and the inside of the filter box 4, preventing the sand from passing through the gaps in the filter path, making it difficult for the purity of the filtered sand to meet the standards. At the same time, the sealing plate 401 adopts a detachable screw connection design, which is convenient for cleaning impurities on the filter assembly 13 at a later time.

[0027] In this embodiment, a handrail is provided on the outside of the arc-shaped door 2 , and a sealing strip is provided on the arc-shaped door 2 .

[0028] Through the above structure, the sealing strip provided on the arc door 2 ensures the sealing performance of the arc door 2 when it is closed, thereby preventing sand from overflowing during the sandblasting process and causing air pollution.

[0029] In this embodiment, a partition 703 is provided inside the silo 7 , and the sandblasting pump 9 is located below the partition 703 . A through opening 704 is provided on the partition 703 , and the through opening 704 is connected to the suction end of the sandblasting pump 9 .

[0030] Through the above structure, when the sandblasting pump 9 is started, it sucks the sand in the hopper 7 into the sandblasting tube 10 through the port 704, and then the sandblasting tube 10 transports the high-pressure sand to the high-pressure nozzle 11. Under the action of the high-pressure nozzle 11, a high-pressure sand jet is formed to act on the metal workpiece to sandblast its surface.

[0031] In the present invention, when in use, before the sandblasting work is carried out, sand is first added to the hopper 7 through the feeding port 701. After the feeding is completed, the sealing buckle cover 702 is buckled on the feeding port 701, and the metal workpiece to be sandblasted is placed on the support 12 at the bottom of the sandblasting tank 1, and then the arc door 2 is closed, and the equipment is started to work. When the sandblasting pump 9 is started, it sucks the sand in the hopper 7 into the sandblasting tube 10 through the port 704, and then the sandblasting tube 10 conveys high-pressure sand to the high-pressure nozzle 11. Under the action of the high-pressure nozzle 11, a high-pressure sand jet is formed to act on the metal workpiece, and the sand after sandblasting is completed. It falls to the bottom of the sandblasting pot 1, and passes through the lower connecting pipe 5 and the filter box 4 under the action of the feed pump 6. In the filter box 4, since the filter assembly 13 is provided with three groups, the large-particle impurities mixed in the sand are gradually filtered out under the step-by-step filtration of the mesh. At the same time, the filter screen 16 is evenly coated with magnetic coating paint, and the filter screen 16 has magnetism to adsorb the iron-nickel metal powder, so that the purity of the sand passing through the filter assembly 13 is guaranteed. The sand after filtration is returned to the silo 7 through the upper connecting pipe 8, forming automatic filtration and circulation of the sand, realizing the automatic recycling of the sand, and reducing the waste of resources.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
