Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of metal surface treatment technology, and more specifically, to a metal surface pretreatment device. Background Technology

[0002] With industrial development, metal products are increasingly used in coating and plating processes. However, impurities such as oil, rust, and oxide scale on metal surfaces can affect the quality of coating and plating, leading to poor product appearance and reduced corrosion resistance. Traditional metal surface pretreatment methods suffer from problems such as poor treatment effects, complex operations, and environmental pollution.

[0003] Existing patent CN220215977U discloses a metal surface pretreatment degreasing and rust removal device. Although it degreases and removes rust from metal parts, it does not treat the waste liquid after cleaning. Instead, it discharges the waste liquid directly through a drain pipe without treatment, which is not conducive to waste liquid recycling. Therefore, a metal surface pretreatment device that filters the waste liquid is designed. Utility Model Content

[0028] like Figure 1-4 As shown, this utility model provides a metal surface pretreatment device, including a conveying assembly 100 and a cleaning assembly 200. The conveying assembly 100 includes a conveyor belt 101, a pallet 102, a rotating rod 103 and a motor 104. The pallet 102 is installed on the outer surface of the conveyor belt 101, the rotating rod 103 is disposed at both ends of the inner side of the conveyor belt 101, and the motor 104 is disposed at one end of the rotating rod 103.

[0029] The cleaning assembly 200 is located at the output end of the conveying assembly 100. The cleaning assembly 200 includes a cleaning tank 201, a water storage tank 202, a conveying pump 203, a filter box 204, a cleaning pipe rack 207, and a water pump 2010. An ultrasonic cleaning assembly 300 is installed inside the cleaning tank 201. The water storage tank 202 and the filter box 204 are respectively installed on both sides of the cleaning tank 201. A conduit 205 is provided between the conveying pump 203 and the water storage tank 202. The conveying pump 203 is connected to the cleaning pipe rack 207, and the water pump 2010 is connected to the filter box 204.

[0030] Furthermore, in this embodiment, the output end of the motor 104 is connected to the rotating rod 103 for transmission, a bracket 106 is screwed to the lower part of the motor 104, the other end of the rotating rod 103 is rotatably connected to the bracket 106, and a control box 105 is screwed to one side of the bracket 106, so that the rotating rod 103 is controlled to rotate by the motor 104.

[0031] In this embodiment, the output end of the control box 105 is electrically connected to the input ends of the motor 104, the conveyor pump 203 and the water pump 2010. Several pallets 102 are equidistantly arranged on the outer surface of the conveyor belt 101. The pallets 102 are screwed to the conveyor belt 101. The control box 105 controls the activation of the motor 104, the conveyor pump 203 and the water pump 2010. The pallets 102 divide the conveyor belt 101 into sections to prevent metal parts from accumulating together.

[0032] In this embodiment, the output end of the conveyor belt 101 is designed to be inclined, which facilitates the transfer of metal parts to the cleaning tank 201. The cleaning tube frame 207 is screwed to the bracket 106 and is located directly above the output end of the conveyor belt 101. Several nozzles 208 are provided on the inner side of the cleaning tube frame 207. Through the position design of the cleaning tube frame 207, the water sprayed by the nozzles 208 is used for preliminary cleaning during the movement of the metal parts, and routine operation settings are performed. Several seepage holes are opened on the conveyor belt 101, and a water collection tank is set at its bottom. The water in the water collection tank is introduced into the filter box 204 for filtration by the water pump 2010.

[0033] In this embodiment, the input end of the delivery pump 203 is connected to the water storage tank 202 through the conduit 205, and the output end of the delivery pump 203 is provided with a diversion pipe 206. The diversion pipe 206 has at least two diversion outlets 2047. One diversion outlet 2047 is connected to the cleaning pipe rack 207, and the other diversion outlet 2047 is connected to the cleaning tank 201. The delivery pump 203 introduces the water in the water storage tank 202 into the cleaning pipe rack 207 and the cleaning tank 201 through the diversion pipe 206, providing a water source for the cleaning pipe rack 207 and the cleaning tank 201.

[0034] In this embodiment, the input end of the water pump 2010 is connected to the bottom or top end near the cleaning tank 201, and the output end of the water pump 2010 is connected to the filter tank 204. A connecting pipe 2041 connected to the water pump 2010 is provided on one side of the filter tank 204. The water pump 2010 sets the water inlet according to the position of the impurities cleaned from the metal parts, such as floating on the water surface or sinking to the bottom, and guides the pumped cleaning water into the filter tank 204.

[0035] In this embodiment, the interior of the filter box 204 is arranged from front to back as follows: a filter grid 2042, a cyclone separation layer 2043, a media filter layer 2045, and an ultrafiltration membrane 2046. The filter grid 2042 is made of metal. The cyclone separation layer 2043 has an inlet 2044 on one side, an overflow port at the top, and an outlet 2047 on the other side. The media filter layer 2045 is one of a sand filter, an activated carbon filter, or a multi-media filter. The ultrafiltration membrane 2046 is one of polyethersulfone, polysulfone, or polyvinylidene fluoride. Large-volume impurities in the water are filtered out by the filter grid 2042, and then... Water enters the hydrocyclone separation layer 2043 through the inlet 2044. The hydrocyclone separation layer 2043 is a hydrocyclone. The centrifugal force generated by the water flow in the hydrocyclone causes suspended particles to move towards the wall and settle at the bottom, thus achieving separation. The water flows into the media filter layer 2045 through the outlet 2047 for further filtration. Finally, smaller particles are removed by the ultrafiltration membrane 2046. The filter grid 2042, media filter layer 2045, and ultrafiltration membrane 2046 use different filter media to filter the impurities in different metal parts, thereby effectively filtering the cleaned water.

[0036] In this embodiment, a shelf 209 is installed inside the cleaning tank 201, and the ultrasonic cleaning assembly 300 is disposed below the shelf 209. The shelf 209 separates the ultrasonic cleaning assembly 300 from the metal parts to be cleaned above it, and the holes on the shelf 209 enable the ultrasonic cleaning assembly 300 to treat water. The ultrasonic cleaning assembly 300 includes an ultrasonic generator 301, a transducer 302, and a vibrating rod 303. The ultrasonic generator 301 and the transducer 302 are screwed to the outside of the cleaning tank 201, and the vibrating rod 303 penetrates one side of the cleaning tank 201 and is attached to the cleaning tank 201. On the other side, the ultrasonic generator 301 is electrically connected to the input of the transducer 302. The output of the transducer 302 is connected to the vibrating rod 303. The electrical signal generated by the ultrasonic generator 301 is transmitted to the transducer 302 and converted into ultrasonic vibration. The vibration generated by the transducer 302 is transmitted to the vibrating rod 303. The vibrating rod 303 generates high-frequency compression and rarefaction waves in the water. The cavitation nuclei (microbubbles) in the liquid will grow and expand, generating a strong micro-jet impact force on the surface of the metal part, peeling off dirt, grease, residues and other substances from the surface of the metal part.

[0037] Specifically, during use, the conveyor belt 101 is divided into sections by the pallet 102, and metal parts are placed in them one by one. The motor 104 is pneumatically driven by the control box 105 to rotate the rotating rod 103. Based on the friction between the transmission rod and the conveyor belt 101, the conveyor belt 101 can move on the outer surface of the rotating rod 103, thereby conveying the metal parts above. During the conveying process, the moving metal parts are initially cleaned by the nozzles 208 on the cleaning tube rack 207.

[0038] Then, the metal parts are moved to the shelf 209 of the cleaning tank 201, and the metal parts are manually arranged. The delivery pump 203 is started to introduce water from the water storage tank 202 into the cleaning tank 201 through the diversion pipe 206. The ultrasonic cleaning component 300 is started, and the cavitation effect of the vibrating rod 303 removes dirt, grease, residues and other substances from the surface of the metal parts. After the cleaning is complete, the water pumping step is selected according to the position of impurities in the cleaning water. When the impurities float on the water surface, the cleaning water is first pumped away from the position near the top of the cleaning tank 201 before the metal parts are taken out. When the impurities settle, the metal parts can be taken out first, and then the cleaning water can be pumped away by the water pump 2010 to avoid the cleaned metal parts being contaminated again. The water is introduced into the filter box 204, and filtered sequentially through the filter grid 2042, the cyclone separation layer 2043, the media filter layer 2045 and the ultrafiltration membrane 2046 in the filter box 204. The water is then discharged for subsequent use or treatment.
