DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] In this embodiment, refer to Figure 1-Figure 8 , a tin mud recovery device for etching wastewater is specifically implemented, comprising a bracket 1, wherein the bracket 1 is provided with a dehydration unit and a feeding unit. The dehydration unit comprises a guide frame 2 and a roller group 3 mounted on the bracket 1, a first filter belt 4 and a second filter belt 5 arranged on the roller group 3, a support plate 6 mounted on the guide frame 2, and a diverter block 8 mounted on the support plate 6, wherein the diverter block 8 is slidably matched with the support plate 6 through a reset spring 7. The guide frame 2 enables the etching wastewater to flow into the first filter belt 4 in an orderly manner for gravity dehydration. And through the setting of the roller group 3, the tin mud falls between the first filter belt 4 and the second filter belt 5. Then, the tin mud is driven by the rotation of the first filter belt 4 and the second filter belt 5, and the tin mud is efficiently squeezed to separate the etching wastewater and the tin mud. The support plate 6 provides a stable installation base for the diverter block 8, and a fixed block for limiting the rotation of the diverter block 8 is installed on the support plate 6. The support plate 6 realizes the slidable installation of the diverter block 8 through the reset spring 7, so that it can be tightly attached to the first filter belt 4 to evenly disperse the tin mud on the first filter belt 4, thereby improving the drainage effect of gravity dehydration. The unloading unit includes an adjustment plate 9 installed on the bracket 1, a slidable scraper 10 arranged on the adjustment plate 9, and a receiving plate 11 for cooperating with the scraper 10. The adjustment plate 9 is provided with a screw for controlling the sliding of the scraper 10. By rotating the screw, the scraper 10 can be quickly adjusted to slide and cooperate with the first filter belt 4 and the second filter belt 5, and the tin mud after drainage is scraped to the receiving plate 11, and the tin mud is discharged from the tin mud recovery device through the receiving plate 11, making the tin mud recovery work more convenient and efficient.

[0030] Furthermore, the support 1 also includes a drainage assembly, which includes a wastewater tank 12 installed at the lower end of the support 1, a water receiving trough 13 provided at the lower end of the guide frame 2, a water guide plate 14 provided at the lower end of the water receiving trough 13 and inclined downward, and a water guide pipe 15 for cooperating with the water guide plate 14. The wastewater tank 12 is used to receive wastewater discharged from the tin mud recovery device, the water receiving trough 13 collects wastewater discharged from the first filter belt 4 by gravity, and guides the wastewater to the water guide pipe 15 through the water guide plate 14, and then discharges the wastewater into the wastewater tank 12.

[0031] Furthermore, the bracket 1 and the water guide plate 14 are respectively provided with a limiting groove 16 and a limiting block 17 that cooperate with each other, and a limiting block 18 is provided at one end of the limiting block 17. Through the mutual cooperation of the limiting groove 16 and the limiting block 17, the stable installation of the water guide plate 14 on the bracket 1 can be ensured, and the limiting block 18 enables the water guide plate 14 to be quickly pushed to the corresponding position, cooperate with the water guide pipe 15, and discharge the wastewater to the wastewater tank 12.

[0032] Furthermore, the water receiving tank 13 is provided with support bars 19 for supporting the first filter belt 4. Gaps are left between the support bars 19 to support the first filter belt 4 and prevent it from sagging excessively due to gravity. At the same time, these gaps also provide a flow channel for the wastewater flowing down from the first filter belt 4, so that the wastewater can flow smoothly into the water receiving tank 13. The design of the support bars 19 makes the structure of the entire tin sludge recovery device more stable and also improves the efficiency of wastewater treatment.

[0033] Furthermore, the support frame 20 is provided on the bracket 1 to cooperate with the second filter belt 5. The support frame 20 enables the second filter belt 5 to be better supported when the tin sludge and etching wastewater fall into the second filter belt 5 after gravity drainage, thereby avoiding deformation of the second filter belt 5 due to impact, thereby ensuring the stable operation of the entire tin sludge recovery device.

[0034] Furthermore, gradually shrinking baffles 21 are provided on both sides of the guide frame 2. The gradually shrinking baffles 21 push the tin mud to the middle of the first filter belt 4, so that the tin mud is more concentrated when falling into the second filter belt 5, fully squeezing the tin mud and discharging the etching wastewater in the tin mud.

[0035] Furthermore, a buffer plate 22 is provided at one end of the guide frame 2. The buffer plate 22 buffers the etching wastewater falling into the first filter belt 4, avoiding direct impact on the first filter belt 4, thereby extending the service life of the first filter belt 4. At the same time, the buffer plate 22 can also make the etching wastewater more uniform when flowing into the first filter belt 4, thereby improving the dehydration effect.

[0036] Furthermore, guide posts 23 are provided at both ends of the adjustment plate 9, and the guide posts 23 are provided with compression springs 24 that cooperate with the scraper 10. Through the cooperation between the guide posts 23 and the compression springs 24, the scraper 10 can slide stably on the adjustment plate 9 and maintain a certain pressure during the sliding process, thereby ensuring that the scraper 10 can effectively and completely fit with the first filter belt 4 and the second filter belt 5, and scrape the drained tin sludge to the receiving plate 11.

[0037] Furthermore, the bracket 1 is equipped with a motor 25 for connecting and cooperating with the roller group 3. The motor 25 is connected to the roller group 3 through a belt, thereby driving the first filter belt 4 and the second filter belt 5 to rotate. The belt connection can effectively reduce the size of the tin sludge recovery device and save space. At the same time, the belt connection method also makes maintenance more convenient, and only the belt needs to be simply replaced without disassembling the entire device.

[0038] Beneficial effects of the utility model: through the cooperation between the first filter belt 4 and the second filter belt 5 on the guide frame 2 and the roller group 3, the wastewater is separated from the tin mud by gravity and extrusion. And through the cooperation between the diverter block 8 and the reset spring 7, the diverter block 8 firmly presses the first filter belt 4 to evenly spread the tin mud. Then, the slidable scraper 10 is pressed against the first filter belt 4 and the second filter belt 5 to scrape the drained tin mud into the receiving plate 11. This improves the practicality and convenience of the tin mud recovery device.
