Description

Technical Field

[0001] The present invention specifically relates to a cleaning device for metal parts and a cleaning method thereof. Background Art

[0002] After general machining of copper and copper alloy workpieces, it is necessary to carry out anti-rust treatment to improve their discoloration resistance and corrosion resistance.

[0003] For the passivation of existing copper and copper alloy products, mainly chromic acid and other treatment liquids or their mixtures are used for cleaning. After preliminary cleaning, it is necessary to transfer to a drying device such as a spin-drying device or a hot air device for drying, and then carry out cleaning again. It is not convenient to directly carry out rapid drying after preliminary cleaning. Multiple processes are time-consuming, affecting the processing efficiency, and the single soaking cleaning effect is not good. In addition, when cleaning, using these treatment liquids for cleaning, the wastewater after treatment contains hexavalent chromium ions, polluting the environment and affecting the health of operators. Therefore, we propose a cleaning device for metal parts and a cleaning method thereof. Summary of the Invention

[0004] The purpose of the present invention is to provide a cleaning device for metal parts and a cleaning method thereof to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A cleaning device for metal parts, comprising:

[0006] A base, on which a vertical cylinder is fixed;

[0007] A top block, arranged on the vertical cylinder, and a support block connected to the vertical cylinder is arranged on the outer surface of the top block;

[0008] A winch, fixed on the top block, and a lifting rope is connected to the output shaft of the winch;

[0009] A lifting assembly, rotatably installed at one end of the lifting rope, and a placement assembly for placing metal parts is arranged inside the lifting assembly;

[0010] A driving assembly, arranged on the outer surface of the top block to drive the placement assembly to rotate to spin-dry the cleaning liquid;

[0011] Wherein, the vertical cylinder includes an immersion area and a spraying area, and the immersion area and the spraying area are sequentially distributed along the vertical direction of the vertical cylinder.

[0012] Preferably, the placement assembly includes a placement groove, a slider, a clamping groove and a discharge port. A first annular cylinder protrudes upward from the inner bottom surface of the placement groove, and a clamping groove is formed on the outer surface of the first annular cylinder along its circumferential direction. A hook is rotatably installed inside the top block, and the hook cooperates with the clamping groove. A hook for withdrawing the hook from the inside of the clamping groove is slidably connected to the lower end inside the clamping groove. A discharge port is opened at the lower end of the outer surface of the placement groove.

[0013] Preferably, the lifting assembly includes a lifting plate, a second filter hole, and a baffle. The edge of the lifting plate extends upward to form a baffle that blocks the discharge port. A second cylinder that slides inside the first cylinder is fixed on the lifting plate, and a baffle is slidably connected inside the second cylinder. The baffle is rotationally engaged with the connecting block at one end of the lifting rope.

[0014] Preferably, a first filter hole is formed through the inner side of the placement groove, and a second filter hole that cooperates with the first filter hole to drain liquid is formed through the inner side of the lifting plate.

[0015] Preferably, the driving assembly includes a driving motor, a gear, and a toothed plate. The driving motor is fixed on the outer surface of the top block. A gear is installed at the lower end of the driving motor. The toothed plate is fixed on the upper end of the outer surface of the placement assembly to cooperate with the gear.

[0016] Preferably, a communication cavity is formed in the middle of the inner side of the top block. An air blowing port that penetrates the lower surface of the top block is formed at the bottom end of the communication cavity. An air inlet is provided on the top block and is connected to the communication cavity.

[0017] Preferably, a ring sleeve is fixed on the outer surface of the vertical cylinder. A diversion cavity is formed between the ring sleeve and the vertical cylinder. Spray holes corresponding to the spraying area are formed inside the diversion cavity. A liquid storage tank is provided corresponding to the ring sleeve at the lower end of the outer surface of the base. A filter screen plate is provided on the liquid storage tank.

[0018] Preferably, a ring block is fixed on the outer surface of the vertical cylinder through a support rod, and a liquid adding pipe that communicates with the inside of the diversion cavity is provided on the front surface of the ring block.

[0019] Preferably, a feeding hole is formed in the inner side of the top block, and a cover plate corresponding to the feeding hole is rotatably installed on the top block.

[0020] A cleaning method for a cleaning device of metal parts includes the following steps:

[0021] Step A: Pour hydrocarbon liquid into the soaking area. Place the metal parts into the placement groove through the feeding hole. Then, the winch drives the lifting assembly and the placement assembly to descend through the lifting rope, and lower the metal parts into the soaking area for cleaning. The liquid adding pipe is externally connected to the hydrocarbon liquid pipeline;

[0022] Step B: After cleaning, the winch drives the metal parts to rise through the lifting rope. When moving to the spraying area, the hydrocarbon liquid inside the liquid adding pipe passes through the ring sleeve and sprays out from the spray holes to wash the metal parts inside the placement groove. Then, the lifting rope continues to drive the metal parts to rise until the toothed plate meshes with the gear. At this time, the grab hook cooperates with the card slot;

[0023] Step C: The driving motor drives the placement component to rotate through the gear and the tooth plate, and at the same time, the air inlet is connected to the gas, and the air flow is ejected from the blowing port through the connecting cavity to dry the surface of the metal part. The rotation force of the placement component throws out the hydrocarbon liquid remaining on the surface of the metal part, and the thrown hydrocarbon liquid falls along the inner wall of the ring block and falls into the inner side of the liquid storage tank for subsequent collection and reuse;

[0024] Step D: After drying, the lifting rope is lowered to lower the lifting assembly. Since the grab hook supports the placement assembly, the height of the placement assembly remains unchanged. At this time, the baffle plate is staggered from the discharge port, and the metal part slides out from the discharge port, falls onto the liquid storage tank through the gap between the ring block and the ring sleeve, and slides out along the inclined filter screen plate;

[0025] Step E: After the metal parts are discharged from the placement component, the lifting component is driven up by the lifting rope, and the placement component is driven up by the lifting component. At this time, the slider is pulled out from the inner side of the slot against the hook, and the placement component is lowered along with the lifting component, and then another batch of metal parts to be cleaned can be put into the placement slot;

[0026] Step F: After the metal parts are initially cleaned, they are placed in a pure hydrocarbon tank for rinsing, then soaked, and then dried;

[0027] Step G: Inspect the surface of the metal parts, and then store the qualified metal parts in a dry environment.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention is provided with a winch, a lifting component, a placement component and a driving component to avoid the inconvenience of quickly drying the metal parts after cleaning. The device can effectively dry the surface of the metal parts through the centrifugal force and airflow during rotation, thereby improving the processing efficiency, reducing the inconvenience of transferring the metal parts in multiple process parts, and improving practicality. Moreover, by setting up a spraying area, the surface of the metal parts after cleaning can be sprayed well, thereby improving the cleaning effect of the metal parts. The cleaning liquid adopts hydrocarbon, which can effectively reduce wastewater pollution. The use of hydrocarbon can gradually achieve the removal of metal surface oil and surface rust prevention treatment during the cleaning process. The cleaning cost is low, the pollution is small, and the waste liquid after washing can be recycled and reused, which has a good market prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Step A: Hydrocarbon liquid is filled into the soaking area 201, the metal part is placed into the inner side of the placing groove 141 through the feeding hole 6, and then the winch 11 drives the lifting component 13 and the placing component 14 to descend through the lifting rope 12, and the metal part is lowered into the soaking area 201 for cleaning. The liquid adding pipe 8 is externally connected to a hydrocarbon liquid pipeline;

[0065] Step B: After cleaning, the winch 11 drives the metal part to rise through the lifting rope 12.

[0068] Step E: After the metal part is discharged from the placement component 14, the suspension rope 12 drives the lifting component 13 to rise, and the lifting component 13 drives the placement component 14 to rise. At this time, the slider 142 abuts against the grab hook 16 and withdraws from the inner side of the card slot 143, and the placement component 14 follows the lifting component 13 to descend, and then another batch of metal parts to be cleaned can be put into the placement groove 141;
