Description

Technical Field

[0001] The present application relates to the field of electroplating, and in particular to an electroplating receiving tray cleaning device and a cleaning method. Background Art

[0002] In the operation of continuous electroplating of steel strip coils, the entire roll of steel strip is usually unrolled from beginning to end and passed through the continuous electroplating equipment to complete the electroplating work. The receiving machine placed at the end of the continuous electroplating equipment then rolls the electroplated steel strip back to its original state for packaging and transportation.

[0003] Currently, the cleaning of the receiving tray is mainly completed by flushing or soaking, which has low cleaning efficiency and poor cleaning effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the current method of cleaning the receiving tray by flushing or soaking has low cleaning efficiency and poor cleaning effect.

[0005] To this end, the present invention provides an electroplating receiving tray cleaning device and a cleaning method.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A method for cleaning an electroplating receiving tray comprises the following steps:

[0008] Rotate the receiving tray, and wash and filter the receiving tray with clean water by combining flushing and soaking;

[0009] The cleaned receiving tray is dried by first using cold air and then hot air.

[0010] By adopting the above technical scheme, a combination of spraying and soaking can be used to achieve fast, efficient and precise cleaning for different degrees of dirt, thereby improving cleaning efficiency and reducing energy consumption. The cold air will blow away the water droplets on the receiving tray, so that the water droplets on the receiving tray are dispersed into multiple smaller water droplets, and then hot air is blown to dry the water droplets on the receiving tray. Since the cold air blows away the water droplets on the receiving tray into small water droplets, the hot air dries the receiving tray, which speeds up the drying of the receiving tray and reduces the energy consumption of the drying operation.

[0011] Furthermore, the middle part of the receiving tray is rinsed.

[0012] By adopting the above technical scheme, since the middle part of the receiving tray is the manual grabbing position, it is the concentrated position of surface oil, and the round hole in the middle part of the receiving tray is the mechanical positioning area. When the receiving tray is in use, it rubs against the positioning shafts on other mechanical parts, which is easy to produce oil and stains. Therefore, the middle part of the receiving tray is sprayed with a nozzle, and the cleaning effect is better. The surface of the edge of the receiving tray is mostly dusty, and the dust can also be cleaned by soaking.

[0013] Furthermore, the receiving tray is continuously scrubbed with a brush during the process of washing and filtering the receiving tray with clean water.

[0014] Furthermore, when filtering and washing with clean water, the used circulating water is first used for washing, and then new clean water is used for filtering and washing.

[0015] A cleaning device for an electroplating receiving tray, comprising:

[0016] Cleaning pool, and

[0017] A fixing mechanism, the fixing mechanism is used to store the receiving tray in the cleaning tank;

[0018] A washing tank, the washing tank being used to store washing water;

[0019] A circulation pool, the circulation pool is used to store water after filtering and washing the receiving tray;

[0020] A nozzle, the nozzle is arranged in the cleaning tank, and the nozzle is used to spray liquid on the receiving tray;

[0021] A circulation component, the circulation component is used to input the washing water in the washing tank or the washing water and clean water in the circulation tank toward the cleaning tank through the nozzle, and to input the water accumulated in the cleaning tank back to the washing tank or the circulation tank;

[0022] A drying device is used to dry the receiving tray in the cleaning tank using cold air or hot air.

[0023] Furthermore, the bottom wall of the cleaning pool includes a sinking plate and two straight plates, and the two straight plates are symmetrically connected on both sides of the sinking plate along the length direction of the sinking plate. From the cross-section perpendicular to the length direction of the cleaning pool, the cross-section of the sinking plate is set to be U-shaped with the opening facing the mouth of the cleaning pool, and the two relative branches of the sinking plate are both inclined away from the horizontal part in the middle of the sinking plate and connected to the straight plate.

[0024] Furthermore, the fixing mechanism includes a limit rod, a pressure rod and a limit ring. The length directions of the limit rod and the pressure rod are arranged along the length direction of the cleaning tank. The limit rod is rotatably arranged at a position close to the bottom of the cleaning tank and two are symmetrically arranged about the central axis arranged at the bottom of the cleaning tank along its length direction. The pressure rod is arranged close to the top of the cleaning tank and located between the two limit rods. The pressure rod is movably connected in the cleaning tank. The limit rod and the pressure rod are coaxially provided with multiple limit rings for limiting the receiving tray along their length direction.

[0025] Furthermore, a guide plate is connected in the cleaning pool, and a plurality of through openings for the receiving tray to pass through are arranged on the guide plate, and the through openings are opposite to the gap between the limiting rings.

[0026] Furthermore, a water pipe is connected to the outer wall of the cleaning pool along the length direction of the cleaning pool, and a plurality of extension pipes are arranged on the water pipe along its length direction. The extension pipes penetrate the side wall of the cleaning pool and extend into the cleaning pool. The extension pipes are arranged opposite to the limiting ring, and the nozzle is connected to the extension pipe and opposite to the middle part of the receiving tray.

[0027] Furthermore, an overflow pipe is connected to the cleaning pool, and the higher end of the overflow pipe in the vertical direction is connected to the cleaning pool, and the other end is connected to the washing pool and the circulation pool. The connection between the overflow pipe and the cleaning pool is located near the lower part of the receiving tray and is located at 1 / 3 of the receiving tray.

[0028] The beneficial effect of the present invention is that the combination of spraying and soaking can achieve fast, efficient and precise cleaning for different degrees of dirt, thereby improving cleaning efficiency and reducing energy consumption. The receiving tray is dried in a cold-first-hot-later manner, and the cold air blows away the water droplets attached to the receiving tray, so that the water droplets attached to the receiving tray are dispersed into multiple smaller water droplets, and then hot air is blown to dry the water droplets on the receiving tray. Since the cold air blows away the water droplets attached to the receiving tray into small water droplets, when the hot air dries the receiving tray, the drying speed of the receiving tray is accelerated, and the energy consumption of the drying operation can be reduced at the same time.

[0059] A receiving tray cleaning method based on the above-mentioned receiving tray cleaning device comprises:

[0060] Start the motor 230 and the driving source 34 so that the brush 33 and the receiving tray keep rotating during the cleaning process. The rotation speed is adjusted by the rotation speed of the motor 230, and the rotation speed range is 5-10m / min. If the rotation speed of the receiving tray exceeds 10m / min, slippage may occur between the receiving tray and the limit assembly 20.

[0061] Step 1: First cleaning

[0062] The washing water in the washing tank 301 is pumped toward the cleaning tank 1 through the vertical pump 320 and filtered by the filter barrel 321. The washing water is sprayed out from the washing water nozzle 312 and sprayed on the receiving tray. The washing water accumulates in the cleaning tank 1. The washing water accumulated in the cleaning tank 1 soaks the lower part of the receiving tray, specifically the lower 1 / 3 of the receiving tray. The washing water is continuously sprayed out from the nozzle 312, and the sprayed washing water rinses the upper 2 / 3 of the receiving tray. The water in the cleaning tank 1 flows back to the washing tank 301 through the overflow pipe 323, thereby maintaining the height of the washing water in the cleaning tank 1.

[0063] The motor 230 of the brush 33 is started while cleaning, and the motor 230 of the brush 33 drives the cleaning brush to rotate, so that while the washing water cleans the receiving tray, the brush 33 brushes the outer edge portion of the receiving tray.

[0064] When the washing water in the cleaning tank 1 accumulates to the lower 1 / 3 of the receiving tray, the upper part of the receiving tray is continuously sprayed, and then the washing water in the cleaning tank 1 is discharged back to the washing tank 301 through the drain pipe 324.

[0065] Reference Figure 3 Since the middle part of the receiving tray is the manual grabbing position, it is the concentrated position of surface oil stains, and the round hole in the middle part of the receiving tray is the mechanical positioning area. When the receiving tray is in use, it rubs against the positioning shafts on other mechanical parts, which is easy to produce oil stains and stains. Therefore, the nozzle 312 is used to spray the middle part of the receiving tray, and the cleaning effect is better.

[0066] The edge of the receiving tray is mostly covered with dust, which can be cleaned by soaking.

[0067] The combination of spraying and soaking can achieve fast, efficient and precise cleaning for different degrees of dirt, thereby improving cleaning efficiency and reducing energy consumption.

[0068] Step 2: Circulating water filtration

[0069] Close the one-way valve between the washing tank 301 and the cleaning tank 1, open the one-way valve between the circulation tank 302 and the cleaning tank 1, and pump the water in the circulation tank 302 toward the cleaning tank 1 through the vertical pump 320 and after being filtered by the filter barrel 321. The water is sprayed out from the nozzle 312, and the water is sprayed on the receiving tray, and then accumulated in the cleaning tank 1. The clean water accumulated in the cleaning tank 1 soaks the lower 1 / 3 of the receiving tray, and the water is continuously sprayed out from the nozzle 312. The sprayed water rinses the upper 2 / 3 of the receiving tray. When the washing water in the cleaning tank 1 accumulates to the lower 1 / 3 of the receiving tray, it continues to spray the upper part of the receiving tray. The water accumulated in the cleaning tank 1 flows back to the circulation tank 302 through the overflow pipe 323, thereby maintaining the height of the clean water in the cleaning tank 1.

[0070] When the washing water in the cleaning tank 1 accumulates to the lower 1 / 3 of the receiving tray, the upper part of the receiving tray is continuously sprayed, and then the water in the cleaning tank 1 is discharged back to the circulation tank 302 through the drain pipe 324.

[0071] Step 3: Filter and wash with clean water

[0072] Close the one-way valves between the washing tank 301, the circulation tank 302 and the cleaning tank 1, open the one-way valve on the clean water pipe 327, spray clean water through the clean water pipe 327 and the nozzle 312, spray clean water on the receiving tray, and then accumulate in the cleaning tank 1. The clean water accumulated in the cleaning tank 1 soaks the lower 1 / 3 of the receiving tray, and the clean water continues to spray from the nozzle 312. The sprayed water rinses the upper 2 / 3 of the receiving tray. When the washing water in the cleaning tank 1 accumulates to the lower 1 / 3 of the receiving tray, it continues to spray the upper part of the receiving tray. The water accumulated in the cleaning tank 1 flows back to the circulation tank 302 through the overflow pipe 323, thereby maintaining the height of the clean water in the cleaning tank 1. After the clean water is filtered and washed, the clean water in the cleaning tank 1 is discharged into the circulation tank 302.

[0073] Step 4: Drying

[0074] After the water washing is completed, the driving source 34 is turned off and the fan 40 is started. The fan 40 blows cold air from both sides of the cleaning tank 1 toward the receiving tray in the cleaning tank 1. The cold air blows away the water droplets on the receiving tray, so that the water droplets on the receiving tray are dispersed into multiple smaller water droplets. Then the heater 41 is started. The fan 40 blows hot air from both sides of the cleaning tank 1 toward the receiving tray in the cleaning tank 1 to dry the water droplets on the receiving tray. Since the cold air blows away the water droplets on the receiving tray into small water droplets, the hot air dries the receiving tray, which speeds up the drying speed of the receiving tray and reduces the energy consumption of the drying operation.

[0075] In summary, the combination of spraying and soaking can achieve fast, efficient and precise cleaning for different degrees of dirt, thereby improving cleaning efficiency and reducing energy consumption. The receiving tray is dried in a cold-then-hot manner. The cold air blows away the water droplets on the receiving tray, so that the water droplets on the receiving tray are dispersed into multiple smaller water droplets. Then hot air is blown to dry the water droplets on the receiving tray. Since the cold air blows away the water droplets on the receiving tray into small water droplets, the hot air dries the receiving tray, which speeds up the drying of the receiving tray and reduces the energy consumption of the drying operation.

[0076] During the cleaning process, the washing water and the clean water and circulating water used for filtering and washing the receiving tray are collected and reused through the filter barrel 321, thereby improving the utilization rate of the liquid.

[0077] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
