Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, in particular to a large workpiece processing device. Background Art

[0002] In order to achieve a better painting effect, metal parts need to be processed before the painting process to remove impurities such as oil stains and dust on the surface of the parts. This is a crucial basic process in the entire painting process flow, because painting can not only make the product look bright, but more importantly, it can improve the corrosion resistance and oxidation resistance of the product, thereby greatly extending the service life of the product.

[0003] Currently, there are two methods for the pretreatment of large metal parts: immersion tank type and spray type. The immersion tank type has relatively low investment cost and relatively small floor area, but the amount of waste liquid generated and required to be treated is large; the spray type has relatively large investment, relatively larger floor area, higher energy consumption, but very low waste water volume, and the production efficiency and treatment effect are better than those of the immersion tank type.

[0029] The following are specific embodiments of the present utility model, in conjunction with the accompanying drawings, to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0030] Figure 3 The arrow in [Figure] shows the schematic diagram of the flow of water after it is sprayed out by the nozzle.

[0031] As Figures 1 to 3 shown, a large workpiece processing device includes: a plurality of water tanks 2 arranged in parallel, a track device 3, and a top wall 7. A partition 21 is installed on the water tank 2 to isolate each water tank 2 from each other and form a channel 22. A number of nozzles 23 for spraying and washing workpieces are fixed on the partition 21; the track device 3 is fixedly arranged above the water tank 2. The track device 3 has an S-shaped guide rail structure 31 wound around a plurality of channels 22. A suspension chain 32 is arranged on the guide rail, and the suspension chain 32 is used to hang workpieces; the top wall 7 is fixed on the upper part of the partition 21 and covers the track device 3.

[0032] In this application, the large workpiece to be processed is hung on the guide rail of the track device 3 through the suspension chain 32. Since the track device 3 has an S-shaped guide rail structure wound around a plurality of channels 22, when the relevant power device is started, the suspension chain 32 will move along the guide rail, thereby driving the workpiece to pass above each water tank 2 in turn. The relevant content of the track device 3 is well-known prior art and will not be elaborated in detail here. During the movement of the workpiece, the partition 21 installed on the water tank 2 isolates each water tank 2 from each other and forms a channel 22, and a number of nozzles 23 for spraying and washing workpieces are fixed on the partition 21. When the workpiece moves to the position corresponding to the channel 22, the nozzles 23 can spray clean water to spray and wash the workpiece in all directions. The setting of the nozzles 23 can ensure that all parts of the workpiece can be effectively sprayed, so as to realize the cleaning of oil stains, impurities, etc. on the surface of the workpiece or perform specific processing procedures.

[0033] Through the S-shaped guide rail structure of the track device 3 and the suspension chain 32, continuous automatic conveying of workpieces can be realized, so that a plurality of workpieces can pass through each water tank 2 in turn and orderly, greatly improving the processing efficiency and being suitable for the processing operation of large quantities of large workpieces.

[0034] In this application, by setting a plurality of water tanks 2 arranged in parallel and using the partition 21 to form different channels 22, and at the same time reasonably arranging the track device 3 above the water tank 2, the whole device can integrate a plurality of water washing spaces in a limited space. This compact design can effectively utilize the site space.

[0035] Specifically, a water receiving plate 24 is connected to both ends of each water tank 2. The water receiving plate 24 is inclined towards the water tank 2 to make the water flow back towards the water tank 2.

[0036] The water receiving plate 24 can collect the water that may overflow from the water tank 2 or splash out during the processing, and make it flow back towards the water tank 2, realizing the recycling of water, which helps to reduce the water resource consumption in the whole processing process. Especially in large-scale and long-time processing operations of large workpieces, it can significantly save the water cost.

[0037] Specifically, the orthographic projection of the S-shaped guide rail structure 31 is located within the water tank 2 and the water receiving plate 24.

[0038] The water carried out can fall back into the water tank 2 again, saving water resources.

[0039] Specifically, the length directions of each water tank 2 are parallel to each other.

[0040] Specifically, a water pump 4 is fixed at the bottom of each water tank 2, and the water pump 4 is connected to the spray head 23 on the corresponding water tank 2.

[0041] Specifically, an inclined deflector 5 is fixed above each water tank 2. The deflector 5 covers the upper part of the water tank 2. The deflector 5 forms a water inlet 51 with the water tank 2 at the higher side; wherein, along the first direction D, the lowest position of the deflector 5 at the rear side extends into the water inlet 51.

[0042] This design enables each cleaning tank to be separately arranged. The water in the cleaning tank further back is cleaner. Along the first direction D, a stepped cleaning process is formed. It only needs to treat the water quality in the last cleaning tank, greatly saving water and improving the water treatment efficiency, without the need to separately treat each water tank 2.

[0043] Specifically, the water tank 2 at the head end position is connected to the water tank 2 at the last position through a pipeline 61, and a circulation pump 62 and a filtering device 6 are installed on the pipeline 61.

[0044] The circulation pump 62 can drive the liquid to flow from the water tank 2 at the head end position along the pipeline 61 to the water tank 2 at the last position, forming a complete circulation loop. This enables the liquid in the water tank 2 to be reused repeatedly, avoiding the situation that the liquid is discarded after single use, greatly improving the utilization rate of liquid resources. Especially for some processing liquids with high costs, it can effectively reduce the procurement cost of the processing liquid.

[0045] The specific embodiments described herein are only illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
