Description

A screening machine for electroplating sludge materials Technical Field

[0001] This utility model belongs to the field of electroplating sludge technology, and in particular relates to an electroplating sludge material screening machine. Background Technology

[0002] Electroplating sludge is a sediment produced during the treatment of electroplating wastewater. It is mainly composed of heavy metal hydroxides such as copper, chromium, and nickel. It has a complex composition and contains high concentrations of heavy metals. It is characterized by high water content and easy migration of heavy metals. If not treated properly, it can cause serious harm to the environment and human health. Its main components include heavy metal compounds, gypsum, water-soluble salts, and impurities. The water content of newly generated sludge can reach 75%-80%. The main treatment methods for electroplating sludge include solidification and stabilization, biological treatment, thermal treatment, and resource utilization. Before treating electroplating sludge, it needs to be screened to separate the components that meet the dissolution size from a large amount of electroplating sludge. The other larger-sized electroplating sludge is then crushed again.

[0003] Currently, electroplating sludge treatment plants typically use simple screens for screening electroplating sludge. This requires manual labor, such as shovels, to throw piles of sludge onto the screen. This method consumes a lot of manual labor, and it is difficult to screen large quantities of sludge in a short time. Therefore, it is necessary to provide an electroplating sludge material screening machine to solve the above problems. Summary of the Invention

[0004] The technical content of this utility model is to provide an electroplating sludge material screening machine.

[0005] To solve the above problems, this utility model provides an electroplating sludge material screening machine, including a screening barrel, a rotating plate installed at the bottom of the screening barrel, the rotating plate being set in a rotating groove opened at the top of the bottom plate, two sets of support plates symmetrically installed at the top of the bottom plate, a top plate installed at the top of the support plates, a rotating ring installed at the upper outer side of the screening barrel, the rotating ring being set in a rotating groove opened at the inner side of the top plate, a motor installed at the top of the top plate, a drive gear connected to the bottom of the motor, a gear ring installed on the outer side of the screening barrel, a barrel cover installed at the top of the screening barrel through a fixing ring, a screening hopper installed inside the screening barrel, a slot opened at the upper outer side of the screening hopper, in which a limit block is set, a sealing plate installed at the lower front of the screening barrel, and a fixing block installed on the left side of the sealing plate.

The inner diameter of the upper half of the rotating groove is equal to the outer diameter of the screening barrel, and the inner diameter of the lower half of the rotating groove is equal to the diameter of the rotating plate. The bottom of the screening barrel and the rotating plate are set in the rotating groove, and the screening barrel and the bottom plate form a rotating connection.

[0007] As a further solution of this utility model, fixing holes are provided at the four corners of the base plate, and a through groove adapted to the screening barrel is provided on the top plate, in which the screening barrel is disposed. A rotating groove adapted to the rotating ring is provided on the inner side of the through groove on the top plate, in which the rotating ring is disposed. The thickness of the rotating ring is less than the thickness of the top plate. The rotating ring and the rotating groove are rotatably connected. The screening barrel and the top plate are rotatably connected. The screening barrel can rotate on the top of the base plate and the inner side of the top plate.

[0008] As a further solution of this utility model, the bottom shaft of the motor passes through a through hole opened on the left side of the top plate and is fixedly connected to a drive gear installed at the bottom of the top plate. The drive gear meshes with a gear ring, and the motor can drive the gear to rotate.

[0009] As a further solution of this utility model, a set of fixing rings is installed on the top outer side of the screening barrel and the bottom outer side of the barrel cover. The two sets of fixing rings are fixedly connected by eight sets of fixing bolts. Two sets of handles are symmetrically installed on the top of the barrel cover so as to remove the barrel cover from the top of the screening barrel.

[0010] As a further solution of this utility model, four sets of slots are symmetrically opened on the upper outer side of the screening hopper. The top of the slots is set as an open structure and the slots do not penetrate the top of the screening hopper. The limiting block is fixedly installed on the top inner side of the screening barrel. The top of the limiting block is lower than the top of the screening barrel. The limiting block and the slots are compatible. The screening hopper is installed in the upper inner space of the screening barrel. The top of the screening hopper is flush with the top of the screening barrel. The bottom of the screening hopper is located in the middle of the inner side of the screening barrel. Multiple sets of screening holes are evenly opened on the outer side and bottom of the screening hopper. The sieving hopper can be used to screen blocky electroplating sludge.

[0012] Compared with related technologies, the electroplating sludge material screening machine provided by this utility model has the following beneficial effects:

[0013] 1. This utility model features a rotating plate installed at the bottom of a screening barrel, positioned within a groove on the bottom plate. A rotating ring is installed on the top outer side of the screening barrel, positioned within a groove on the inner side of the top plate. This allows the screening barrel to rotate within the top and bottom plates. A motor drives the screening barrel to rotate. Inside the screening barrel is a screening hopper with screening holes on its outer side and bottom. When blocky electroplating sludge is fed into the screening hopper, the rotation of the screening barrel causes the screening hopper to rotate as well. This allows small pieces of electroplating sludge to pass through the screening holes and fall into the bottom space inside the screening barrel, while larger pieces remain inside the screening hopper for subsequent crushing. This achieves the screening of electroplating sludge, making this device more efficient than manual processing.

[0014] 2. This utility model features four sets of limiting blocks installed inside the top of the screening bucket, and four sets of slots symmetrically opened on the upper outer side of the screening bucket. The top of the slots is an open structure, and the slots do not penetrate the top of the screening bucket. When installing the screening bucket into the screening bucket, aligning the four sets of slots with the four sets of limiting blocks allows the limiting blocks to enter the slots, making the installation process of the screening bucket very simple. The four sets of limiting blocks can be used to install the screening bucket into the upper inner space of the screening bucket, with the top of the screening bucket flush with the top of the screening bucket. The bucket lid and the limiting blocks can simultaneously limit the vertical movement of the screening bucket, preventing the screening bucket from shaking vertically when the screening bucket rotates.

[0026] Preferably, the diameter of the rotating plate 2 installed at the bottom of the screening barrel 1 is larger than the outer diameter of the screening barrel 1, and the rotating groove opened at the top of the bottom plate 3 is set as an inverted T-shaped structure. The inner diameter of the upper half of the rotating groove is equal to the outer diameter of the screening barrel 1, and the inner diameter of the lower half of the rotating groove is equal to the diameter of the rotating plate 2. The bottom of the screening barrel 1 and the rotating plate 2 are set in the rotating groove, so that the screening barrel 1 and the bottom plate 3 form a rotating connection.

[0027] Preferably, the base plate 3 has fixing holes at all four corners, in which fixing bolts can be installed, so that the base plate 3 can be fixedly installed on the ground of the electroplating sludge treatment workshop, thereby realizing the fixed installation of the whole device in the electroplating sludge treatment workshop, making the device more stable during operation. The top plate 5 has a through groove adapted to the screening barrel 1, in which the screening barrel 1 is placed. The inner side of the through groove on the top plate 5 has a rotating groove adapted to the rotating ring 6, in which the rotating ring 6 is placed. The thickness of the rotating ring 6 is less than the thickness of the top plate 5, so that the rotating ring 6 and the rotating groove are rotatably connected, thereby making the screening barrel 1 and the top plate 5 rotatably connected. The screening barrel 1 can rotate on the top of the base plate 3 and the inner side of the top plate 5. The base plate 3, the two sets of support plates 4 and the top plate 5 can provide support for the screening barrel 1, so that it will not shake when rotating.

The drive gear 8 meshes with the gear ring 9. The motor 7 can drive the gear 8 to rotate, thereby causing the gear ring 9 to drive the screening barrel 1 to rotate.

[0029] Preferably, a set of fixing rings 10 are installed on the top outer side of the screening barrel 1 and the bottom outer side of the barrel cover 11. The two sets of fixing rings 10 are fixedly connected by eight sets of fixing bolts, thereby fixing the barrel cover 11 on the top of the screening barrel 1 and closing the screening barrel 1. Two sets of handles are symmetrically installed on the top of the barrel cover 11 so as to remove the barrel cover 11 from the top of the screening barrel 1.

When the screening hopper 12 is installed into the screening barrel 1, the four sets of slots are aligned with the four sets of limiting blocks 13, so that the limiting blocks 13 can enter the slots. Thus, the screening hopper 12 is installed in the upper inner space of the screening barrel 1 by the four sets of limiting blocks 13. The top of the screening hopper 12 is flush with the top of the screening barrel 1. Then, the barrel cover 11 and the limiting blocks 13 can simultaneously limit the vertical movement of the screening hopper 12, so that the screening hopper 12 can be positioned in the upper inner space of the screening barrel 1.

Then, the barrel cover 11 is installed on the top of the screening barrel 1 and the screening barrel 1 is driven to rotate by the motor 7. The electroplating sludge can be screened through the screening hopper 12, so that small pieces of electroplating sludge fall through the screening holes into the bottom space inside the screening barrel 1. Large pieces of electroplating sludge remain inside the screening hopper 12 for subsequent crushing. The interior of the screening barrel 1 is designed as a large space structure, which can accommodate a large amount of block electroplating sludge.

[0031] Preferably, the lower front end of the screening barrel 1 is configured as an open structure, the size of which is adapted to the size of the sealing plate 14. The top and bottom right sides of the sealing plate 14 are provided with rotating shafts, which are installed in the rotating grooves opened on the top and bottom right sides of the bottom opening of the screening barrel 1, thereby making the sealing plate 14 and the screening barrel 1 rotatably connected. The fixing block 15 installed on the left side of the sealing plate 14 is set in the fixing groove opened on the left side of the opening at the lower front end of the screening barrel 1. The depth of the fixing groove is less than the thickness of the screening barrel 1. The fixing block 15 is fixedly installed in the fixing groove by fixing bolts, thereby fixing the sealing plate 14 at the bottom opening of the screening barrel 1. The bottom opening of the screening barrel 1 can be closed by the sealing plate 14. A handle is installed on the outside of the sealing plate 14 so as to pull the sealing plate 14 to rotate, thereby opening the bottom opening of the screening barrel 1, so as to transfer the blocky electroplating sludge screened out inside the screening barrel 1 for subsequent processing.
