[0031] As described in the background section, centrifugal separation equipment is often used to achieve solid-liquid separation in the treatment of heavy metal wastewater. However, after long-term operation, sediment tends to accumulate in the internal mesh of traditional centrifugal separation equipment, resulting in decreased separation efficiency and difficulty in cleaning and maintenance, which increases operating costs.

[0032] To solve this technical problem, this utility model provides a centrifugal separation device for heavy metal wastewater.

[0033] For details, please refer to Figures 1-5The specific components of the heavy metal wastewater centrifugal separation equipment include:

[0034] The base plate 101 has an outer cylinder 2 fixedly installed on its top. The outer cylinder 2 contains a mesh cylinder body 401. The bottom of the mesh cylinder body 401 is fixedly installed with a connecting seat 402. The bottom of the connecting seat 402 is fixedly provided with a slot 403.

The outer surface of the insert block 302 is inserted into the slot 403.

[0035] The heavy metal wastewater centrifugal separation equipment provided by this utility model realizes the transmission of power from the drive motor 3 to the screen body 401 through the setting of the insert block 302, slot 403 and connecting seat 402. Since the slot 403 and the insert block 302 adopt the plug-in design, the screen body 401 can be easily removed from the outer cylinder 2 for cleaning, which effectively reduces the problem of decreased separation efficiency caused by sediment accumulation and extends the service life of the equipment.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example 1, please refer to Figures 1-5 A centrifugal separation device for heavy metal wastewater includes a base plate 101, an outer cylinder 2 fixedly installed on the top of the base plate 101, a screen body 401 disposed inside the outer cylinder 2, a connecting seat 402 fixedly installed on the bottom of the screen body 401, and a slot 403 fixedly opened on the bottom of the connecting seat 402; a drive motor 3 is disposed at the bottom of the base plate 101, the output shaft of the drive motor 3 passes through the base plate 101 and is fixedly connected to an insert block 302, the outer surface of the insert block 302 is inserted into the slot 403; this application realizes the transmission of power from the drive motor 3 to the screen body 401 through the set insert block 302, slot 403 and connecting seat 402. Since the slot 403 and the insert block 302 adopt the insertion design, the screen body 401 can be easily removed from the outer cylinder 2 for cleaning, effectively reducing the problem of decreased separation efficiency caused by sediment accumulation and extending the service life of the equipment.

[0040] Furthermore, a sealed bearing is provided at the connection between the output shaft of the drive motor 3 and the base plate 101. The sealed bearing is used to seal the connection between the output shaft of the drive motor 3 and the base plate 101.

[0041] Furthermore, such as Figures 1-4 As shown, a number of limiting wheels 404 are provided on the outer surface of the net cylinder body 401. The limiting wheels 404 are slidably connected to the inner wall of the outer cylinder 2. A handle 406 is fixedly installed inside the net cylinder body 401. The handle 406 is designed to facilitate the picking up and putting down of the net cylinder body 401. The limiting wheels 404 cooperate with the outer cylinder 2 to limit the rotation of the net cylinder body 401, thereby improving the stability of the net cylinder body 401 during rotation.

[0042] Example 2 further optimizes the heavy metal wastewater centrifugal separation equipment provided in Example 1, specifically, as follows: Figure 1 As shown, a top ring 405 is fixedly installed on the top of the main body 401 of the net cylinder, and a limiting structure 5 is provided on the side of the outer cylinder 2. The limiting structure 5 is in contact with the top of the top ring 405 so that the limiting structure 5 limits the net cylinder main body 401 in the vertical direction through the top ring 405, thereby reducing the upward movement of the net cylinder main body 401 during rotation.

[0043] Furthermore, such as Figure 1 , Figure 5 and Figure 6 As shown, the limiting structure 5 includes a support base 501 fixedly installed on the side of the outer cylinder 2. A connecting shaft 502 is inserted through the middle of the support base 501. A connecting plate 503 is fixedly installed on one side of the connecting shaft 502. A pressure roller 504 is installed at the bottom of the connecting plate 503. The pressure roller 504 contacts the top of the top ring 405. The connecting shaft 502 and the connecting plate 503 cooperate to support the pressure roller 504.

[0044] Furthermore, such as Figure 5 and Figure 6 As shown, a notch 505 is provided on the side of the support base 501 away from the outer cylinder 2. An external threaded rod 507 is fixedly installed on the outer surface of the connecting shaft 502. One end of the external threaded rod 507 passes through the notch 505 and extends to the outside. The external threaded rod 507 can limit the connecting shaft 502 to prevent the connecting shaft 502 from moving upward.

[0045] Furthermore, such as Figure 5 and Figure 6 As shown, a limiting groove 506 is provided on the side of the support base 501. An internal threaded tube 508 is threadedly connected to the outer surface of the external threaded rod 507. One end of the internal threaded tube 508 is inserted into the inner wall of the limiting groove 506. The insertion of the internal threaded tube 508 into the limiting groove 506 can limit the external threaded rod 507 to prevent the external threaded rod 507 and the connecting shaft 502 from rotating, thereby limiting the pressure roller 504.

[0046] Example 3 further optimizes the heavy metal wastewater centrifugal separation equipment provided in Example 1 or 2, specifically, as follows: Figures 1-4 As shown, a number of support columns 102 are fixedly installed at the bottom of the base plate 101, and a connecting ring 103 is fixedly connected between the bottom ends of the support columns 102. The support columns 102 and the connecting ring 103 cooperate with each other to support the base plate 101.

[0047] Furthermore, such as Figure 4 As shown, a motor mounting base 301 is installed between the drive motor 3 and the bottom of the base plate 101. The motor mounting base 301 can provide a connection between the drive motor 3 and the base plate 101 to improve the stability of the drive motor 3 during use.

[0048] Furthermore, such as Figure 1 As shown, a drain pipe 201 is fixedly connected to the bottom of one side of the outer cylinder 2. The drain pipe 201 is used to drain the liquid inside the outer cylinder 2.

[0049] The usage process of the heavy metal wastewater centrifugal separation equipment provided by this utility model is as follows:

[0050] Wastewater containing solids is poured into the screen cylinder body 401. The drive motor 3 is started, and the drive motor 3, through the cooperation of the insert block 302, slot 403, and connecting seat 402, drives the screen cylinder body 401 to rotate centrifugally. This causes the wastewater to pass through the screen cylinder body 401 into the outer cylinder 2 under centrifugal force, achieving solid-liquid separation. The liquid is discharged through the drain pipe 201. During cleaning, the internal threaded pipe 508 is rotated to separate it from the limiting groove 506. The connecting shaft 502 is rotated to move the connecting plate 503 and the pressure roller 504, causing the pressure roller 504 to separate from the top ring 405. Figure 7 and Figure 8 As shown, pulling the handle 406 upwards will remove the main body 401 of the mesh cylinder from the outer cylinder 2 for cleaning. After the main body 401 of the mesh cylinder is removed, the operating space inside the outer cylinder 2 will increase, which will also facilitate cleaning inside the outer cylinder 2. After cleaning, the main body 401 of the mesh cylinder will be put back into the outer cylinder 2, so that the slot 403 is aligned with the insert block 302 and inserted together with the insert block 302. Rotating the connecting shaft 502 will make the pressure roller 504 contact the top of the top ring 405. Rotating the internal thread tube 508 will make the internal thread tube 508 insert together with the limiting groove 506.
