Description

Technical Field

[0001] The utility model belongs to the technical field of electrogalvanizing, and in particular relates to an electrogalvanizing pretreatment device. Background Art

[0002] Galvanizing of pipe fittings refers to a surface treatment technology that coats a layer of zinc on the surface of a metal pipe for aesthetic purposes and to prevent rust. Currently, the surface of the workpiece needs to be cleaned before galvanizing to remove impurities attached to the surface in order to improve the subsequent galvanizing effect. Therefore, a cleaning device is required.

[0003] At present, workpieces are generally cleaned manually before galvanizing. During cleaning, workers put the workpieces into a cleaning tank for soaking, and remove impurities on the surface of the workpieces with a specific liquid. After soaking, the workpieces are taken out and subsequently cleaned. However, each workpiece needs to be manually picked up and cleaned. This cleaning method is very laborious and also results in low cleaning efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a pretreatment device for electrogalvanizing. Figure 1-4 As shown, it includes a cleaning pool 1 and a conveyor belt 2. A hanging plate 3 is installed equidistantly in the horizontal direction on the lower side of the conveyor belt 2. A sleeve plate 4 is sleeved on the outer side of the hanging plate 3. The sleeve plate 4 and the hanging plate 3 are slidably sleeved. A placement frame 5 is connected to the bottom of the sleeve plate 4. A positioning mechanism 6 is installed at the bottom of the hanging plate 3. A guide plate 7 is installed at the upper end of the cleaning pool 1. An arc-shaped guide groove is opened on the side of the guide plate 7. A guide block 8 is installed on the rear side of the sleeve plate 4. A water inlet pipe 9 is installed on the left side of the cleaning pool 1. A water outlet pipe 10 is installed on the right side of the cleaning pool 1. When the device is used, the workpiece to be cleaned can be placed To the placement rack 5, the placement rack 5 is transported from left to right in sequence to the top of the cleaning tank 1 through the conveyor belt 2. At this time, the guide block 8 on the rear side of the sleeve plate 4 slides into the guide groove on the surface of the guide plate 7, and the guide block 8 slides downward under the action of the guide groove, so that the sleeve plate 4 can slide downward, so that the placement rack 5 falls into the cleaning tank, and with the continuous transmission of the conveyor belt 2, the placement rack 5 rises again and is transported away. The device is used in conjunction with the guide plate 7 through the conveyor belt 2, so that the pre-cleaning process of the workpiece can be completed automatically without manual intervention, thereby improving the processing efficiency.

[0021] The positioning mechanism 6 includes a fixed frame 61, a spring 62 and a block 63. The fixed frame 61 is fitted with the inner wall of the sleeve plate 4. The spring 62 is installed inside the fixed frame 61 and the movable end is connected to the block 63. The outer end of the block 63 is set to an arc shape. The inner wall of the sleeve plate 4 is provided with a slot adapted to the block 63. By setting the positioning mechanism 6, the block 63 in the positioning mechanism 6 is inserted into the slot on the inner wall of the sleeve plate 4 under the elastic force of the spring 62, so that the position of the sleeve plate 4 can be positioned. The block 63 can bear the weight of the workpiece and can be pulled by the guide block 8. The setting of the positioning mechanism 6 can enable the cleaned workpiece to be stably transmitted.

[0022] The side walls of the placement rack 5 are all arranged in a mesh shape. By arranging the surface of the placement rack 5 in a mesh shape, it is possible to prevent the cleaning liquid from remaining in the placement rack 5 .

[0023] The height of the bottom end of the inner wall of the cleaning tank 1 gradually decreases from left to right. This arrangement allows the sediment after cleaning to be concentrated at the pipe mouth of the water outlet pipe 10.

[0024] The other end of the outlet pipe 10 is connected to a sewage suction pump 11, and the water outlet of the sewage suction pump 11 is connected to a reflux groove 12. A filter plate 13 is installed in the reflux groove 12, and the other end of the filter plate 13 is connected to the water inlet pipe 9. By providing the sewage suction pump 11 and the reflux groove 12, the sewage suction pump 11 can extract and replace the cleaning liquid in the cleaning tank 1, and the cleaning liquid flows into the cleaning tank 1 again after being filtered by the filter plate 13 in the reflux groove 12, thereby realizing the recycling of the cleaning liquid.

[0025] The filter plate 13 is installed on the top of the reflux trough 12, and the water inlet of the reflux trough 12 is located above the side. By installing the filter plate 13 on the top of the reflux trough 12, this arrangement allows the sediment filtered out by the filter plate 13 to remain at the bottom of the reflux trough 12 without accumulating on the surface of the filter plate 13 to cause blockage.
