Description

Technical Field

[0001] This utility model relates to the field of powder suction box technology, and in particular to a gold powder suction device built into a metal cutting machine. Background Technology

[0002] During the operation of precious metal laser cutting machines, a large amount of precious metal dust, such as gold powder, is generated internally during cutting. In existing technologies, conventional filtration devices can typically collect larger dust particles, but for finer precious metal dust particles, due to their small size and light weight, they easily diffuse with the airflow and often cannot be effectively captured. This results in the precious metal dust being discharged outside the machine with the airflow, causing resource waste and economic losses. Furthermore, some cutting machine designs lack efficient air extraction devices, further exacerbating the problem of precious metal dust dispersion and making collection difficult. Therefore, how to efficiently and conveniently collect these fine precious metal dust particles without affecting the normal operation of the cutting machine has become an urgent technical problem to be solved in this field.

[0003] Therefore, it is necessary to provide a gold powder suction device built into a metal cutting machine to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a gold powder collection device built into a metal cutting machine, which aims to solve the problem of collecting fine gold powder through structural optimization, and to collect these fine precious metal dusts efficiently and conveniently without affecting the normal operation of the cutting machine.

[0005] To achieve the above objectives, this utility model provides a gold powder absorbing device built into a metal cutting machine, comprising: The housing is divided into a first chamber and a second chamber by a partition. The inner wall of the first chamber is provided with an air inlet pipe, which is used to connect the inside of the metal cutting machine with the first chamber. The partition has a through hole connecting the first chamber and the second chamber. The inner wall of the second chamber is provided with an air outlet pipe. A powder-absorbing box is disposed in the first chamber and has a sponge block inside that covers the through hole, so that air entering from the air inlet pipe passes through the sponge block and then enters the through hole; A fan is provided in the second chamber and includes an air inlet and an air outlet; the air inlet is connected to the through hole and the air outlet is connected to the air outlet pipe; the fan is used to drive the air containing gold powder in the metal cutting machine to flow sequentially through the air inlet pipe, the first chamber, the fan, and the air outlet pipe, so that the gold powder is adsorbed on the sponge block.

[0006] In a preferred embodiment, the powder-absorbing box includes a box body and a limiting frame disposed on the inner wall of the box body. The box body is fixed to the inner wall of the first chamber and communicates with the air inlet pipe and the through hole. The limiting frame is used to press the edge of the sponge block against the inner wall of the first chamber on the side where the through hole is located.

[0007] In a preferred embodiment, the inner wall of the second chamber is provided with a fixing frame, and a fan bracket is provided on the fixing frame, and the fan is fixed on the fan bracket.

[0008] In a preferred embodiment, the fan bracket includes a plurality of parallel spaced first heat dissipation fins with fixing holes on their inner sides; the outer surface of the fan is abutted and fixed to the inner wall of the fixing holes.

[0009] In a preferred embodiment, a control module is provided in the second chamber, the control module being used to control the fan to turn on and off at regular intervals.

[0010] In a preferred embodiment, the second chamber is further provided with a fixing plate and a plurality of parallel and spaced second heat dissipation fins on the same side of the fixing plate, and the control module is fixed to the fixing plate.

[0011] In a preferred embodiment, the housing includes a bottom shell, a top cover, and at least two latches; the top cover is fastened to the bottom shell and can be locked by the latches.

[0012] This invention provides a gold powder absorption device built into a metal cutting machine. Its working principle is as follows: a fan drives air containing gold powder inside the metal cutting machine through the inlet pipe into the first chamber. The air first passes through a sponge block in the powder absorption box. The sponge block, as a porous adsorption material, effectively intercepts and adsorbs fine gold powder. Subsequently, the purified air enters the second chamber through holes in a partition and is discharged from the outlet pipe by the fan. In this way, the entire airflow path forms a closed loop inside the device, ensuring that the gold powder is concentrated and adsorbed on the sponge block, preventing it from escaping with the airflow. Therefore, through the physical adsorption characteristics of the sponge block, it can efficiently capture fine gold powder that is difficult for conventional filtration devices to collect, reducing precious metal waste. In practice, each device can collect approximately one gram of gold powder per month, reducing losses. Secondly, the device is built into the cutting machine, has a compact structure, does not occupy extra space, and is easy to integrate into existing equipment. Finally, the fan ensures continuous airflow, improving collection efficiency, and is particularly suitable for cutting machines without an exhaust system, achieving economical and environmentally friendly dust management.

Detailed Implementation

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0018] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0019] In an embodiment of this utility model, a metal dust collection device 100 is provided, which is used to drive the airflow inside the metal cutting machine to collect metal dust that can move with the airflow. It should be noted that the metal cutting machine usually needs to have its cabinet door closed during operation to provide a basic air extraction mechanism.

[0020] like Figures 1-3 As shown, the gold powder suction device 100 built into the metal cutting machine includes a housing 10, a powder suction box 20, and a fan 30.

[0021] The housing 10 is generally square in shape, and its interior is divided into a first chamber 101 and a second chamber 102 by a partition 11. The housing 10 includes a bottom shell 12, a top cover 13, and at least two latches 14. The partition 11 is located inside the bottom shell 12. The top cover 13 is fastened to the bottom shell 12 so that the top cover 13 can close one opening of the bottom shell 12. After the top cover 13 and the bottom shell 12 are fastened, they can be locked by the latches 14. When it is necessary to open the housing 10, the latches 14 are released. It should be noted that the latches 14 can be a conventional press-type fastening structure; the specific structure and implementation principle of this invention will not be described in detail here.

[0022] Specifically, the inner wall of the first chamber 101 is provided with an air inlet pipe 41, which connects the inside of the metal cutting machine with the first chamber 101, thereby connecting the inside of the metal cutting machine with the first chamber 101. The partition 11 has a through hole 103 connecting the first chamber 101 and the second chamber 102. The inner wall of the second chamber 102 is provided with an air outlet pipe 42, which connects to the outside.

[0023] In one embodiment, the dust collection box 20 is disposed in the first chamber 101 and contains a sponge block 21 covering the through hole 103, so that air entering from the air inlet pipe 41 passes through the sponge block 21 and then enters the through hole 103, and then passes through the fan 30 and the exhaust pipe 42 in sequence. The sponge block 21 has a multi-microporous structure, which can effectively physically adsorb fine metal dust.

[0024] The powder-absorbing box 20 includes a box body 22 and a detachable limiting frame 23 disposed on the inner wall of the box body 22. The outer surface of the box body 22 is fixed to the inner wall of the first chamber 101. The box body 22 is also connected to the air inlet pipe 41 and the through hole 103. The limiting frame 23 is used to form a limiting structure, thereby pressing the edge of the sponge block 21 against the inner wall of the first chamber 101 on the side where the through hole 103 is opened, thereby preventing the sponge block 21 from moving within the box body 22.

[0025] The fan 30 is located in the second chamber 102 and includes an air inlet 301 and an air outlet. It should be noted that the structure and operating principle of the fan 30 can be found in existing technology, and will not be described in detail here. The fan 30 drives the airflow from the air inlet 301 to the air outlet. The air inlet 301 is connected to the through hole 103, and the air outlet is connected to the air outlet pipe 42. The fan 30 drives the air containing gold powder in the metal cutting machine to flow sequentially through the air inlet pipe 41, the first chamber 101, the fan 30, and the air outlet pipe 42, so that the gold powder is adsorbed onto the sponge block 21. When the fan 30 is running, it can create a negative pressure in the cutting space of the metal cutting machine, thereby directing the air carrying fine metal dust to flow in a specific direction and removing the metal dust adhering to the inner wall of the cutting space so that it can be carried away by the airflow.

[0026] Specifically, the inner wall of the second chamber 102 is provided with a fixing frame 31. A fan bracket 32 ​​is provided on the fixing frame 31, and the fan 30 is fixed to the fan bracket 32. Further, the fan bracket 32 ​​includes a plurality of parallel spaced first heat dissipation fins 33 with fixing holes 302 on their inner sides. The outer surface of the fan 30 abuts against and is fixed to the inner wall of the fixing holes 302, so that the first heat dissipation fins 33 can effectively dissipate heat for the body of the fan 30.

[0027] In one embodiment, a control module 50 is provided in the second chamber 102. The control module 50 is used to control the fan 30 to turn on and off at regular intervals. It is understood that metal dust often adheres to the surfaces of various components within the cutting area; therefore, periodically turning on the fan 30 to create airflow can effectively collect metal dust and reduce wear and tear on the fan 30. The control module 50 includes components such as a timer; its implementation principle can be found in existing technologies and will not be elaborated here.

[0028] Furthermore, the second chamber 102 is also equipped with a fixing plate 51 and a plurality of parallel and spaced second heat dissipation fins 52 on the same side of the fixing plate 51, and the control module 50 is fixed on the fixing plate 51. Therefore, the control module 50 can be cooled by the second heat dissipation fins 52.

[0029] To make this technical solution more complete, several methods for removing the collected metal dust will be disclosed below: (1) Physical compression: Over a large container, the sponge block 21 is repeatedly and forcefully compressed to dislodge the gold powder particles trapped in the pores. To improve collection efficiency and prevent dust from flying, the sponge block 21 can be soaked in water for compression. Water can effectively suppress dust and cause the gold powder to settle to the bottom of the container. After compression, the container is left to stand to allow the gold powder to settle completely. Then, the clear water on top is carefully poured off, and the remaining sediment (a mixture of gold powder and possible impurities) is filtered and dried through finer filter paper or cloth to obtain purer gold powder.

[0030] (2) Water flow reverse flushing: Use water flow (such as from a wash bottle or a slow tap) to flush in the reverse direction of the air outlet (i.e., simulate the path of airflow entering from the air outlet pipe 42 in the opposite direction and exiting from the air inlet pipe 41). In this way, the power of the water flow can be used to flush out the gold powder that is blocked deep in the pores; let the flushed water flow (a suspension containing gold powder) into a collection tank; and recover the gold powder by settling, filtering and drying.

[0031] (3) Ultrasonic cleaning: Place the sponge block 21 into an ultrasonic cleaning tank filled with clean water; turn on the ultrasonic cleaner, and the high-frequency ultrasonic vibration will generate countless tiny vacuum bubbles in the water and burst instantly (cavitation effect). This powerful impact can penetrate into every tiny pore of the sponge block 21 and completely shake off the gold powder attached to it; after cleaning, take out the sponge block 21, and a large amount of gold powder will be deposited at the bottom of the tank; obtain the gold powder by the steps of settling, pouring water, filtering and drying.

[0032] In summary, the gold powder absorption device 100 built into a metal cutting machine provided by this utility model works on the following principle: A fan 30 drives air containing gold powder inside the metal cutting machine to enter the first chamber 101 through the air inlet pipe 41. The air first passes through the sponge block 21 inside the powder absorption box 20. The sponge block 21, as a porous adsorption material, can effectively intercept and adsorb fine gold powder. Subsequently, the purified air enters the second chamber 102 through the through-hole 103 on the partition 11 and is discharged from the exhaust pipe 42 by the fan 30. In this way, the entire airflow path forms a closed loop inside the device, ensuring that the gold powder is concentrated and adsorbed on the sponge block 21 and does not escape with the airflow. Therefore, through the physical adsorption properties of the sponge block 21, it can efficiently capture fine gold powder that is difficult to collect by conventional filtration devices, reducing the waste of precious metals. In practice, each device can collect an additional gram of gold powder per month, reducing losses. Secondly, the device is built into the cutting machine, with a compact structure that does not occupy extra space and is easy to integrate into existing equipment. Finally, the drive of the fan 30 ensures continuous airflow, improving collection efficiency, and is especially suitable for cutting machines without an exhaust device, achieving economical and environmentally friendly dust management.

[0033] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
