Description

Technical Field

[0001] The present invention relates to the technical field of galvanized part centrifugation, and specifically to a roll-over drum centrifuge. Background Art

[0002] Hot-dip galvanizing is an effective method for metal anti-corrosion. After rust removal, the parts are immersed in the molten zinc solution, so that a zinc layer adheres to the surface of the parts, thereby achieving the purpose of protection. Since the whole part enters the zinc solution, after the part is taken out, the zinc solution on the surface is relatively thick, and at this time, a centrifuge is still needed to remove the excess zinc solution on the surface.

[0003] Currently, most centrifuges adopt a bottom drive method. This method results in the need for an additional container outside the centrifugal basket to collect the centrifuged zinc skins, and then an additional zinc skin recovery work is carried out after centrifugation, which affects the overall work efficiency.

[0004] At the same time, after the centrifugation of galvanized parts is completed, a cooling operation is also required. Most of the current cooling methods require processes such as handling, transferring, and pouring, which result in an increase in the time between the centrifugation process and the cooling process of the galvanized parts, and thus easily lead to the oxidation and darkening of the surface of the galvanized parts, affecting the quality of the galvanized parts.

[0005] Therefore, a roll-over drum centrifuge is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a roll-over drum centrifuge to solve the problems raised in the above background art.

[0008] A transmission mechanism for driving the centrifugal drum to rotate is installed between the central shaft and the large gear, a turning mechanism for pouring centrifuged parts is installed on one side of the housing, and the turning central axis of the turning mechanism is coaxially arranged with the central axis of the central shaft.

[0009] Preferably: The transmission mechanism includes a plurality of rotating shafts; the plurality of rotating shafts are installed inside the housing, transmission gears are installed on each of the plurality of rotating shafts, and the transmission gears are meshed with the large gear; a second bevel gear is installed on one of the rotating shafts, a first bevel gear is installed on the central shaft, and the second bevel gear and the first bevel gear are meshed with each other.

[0010] Preferably, the flipping mechanism includes a sleeve; the sleeve is installed on one side of the housing, a flipping gear is installed on one side of the sleeve, the sleeve and the flipping gear are rotatably connected to the outside of the central shaft, a flipping rack is meshed with the flipping gear, one end of the flipping rack is installed with a flipping driving cylinder, and the flipping driving cylinder is installed on the bracket.

[0011] Preferably, a centrifugal basket is provided on the centrifugal drum, a second driving block is installed on the outside of the centrifugal basket, and a first driving block is installed on the inside of the centrifugal drum.

[0012] Preferably, a retaining wall for blocking the centrifuged zinc sheets is installed below one side of the housing.

[0013] Preferably, a protective cover plate is slidably connected to one side of the bracket, and a cover plate driving cylinder for driving the movement of the protective cover plate is installed on one side of the protective cover plate.

[0014] Preferably, a driving wheel is installed on one side of the central shaft, and a driving motor, a belt pulley, a belt and a clutch brake for driving the driving wheel to rotate are installed inside the bracket.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By driving at the waist of the centrifugal drum, the centrifugal basket can be located directly above the zinc pot, so that the zinc sheets can directly fall into the zinc pot during centrifugation, eliminating the process of using containers to collect zinc sheets and additional recycling.

[0016] Then, after centrifugation is completed, through the coaxial flipping mechanism, the galvanized parts can be quickly poured into the cooling pool, eliminating the processes of handling and transferring, shortening the time between the centrifugation process and the cooling process of the galvanized parts, enabling the galvanized parts to quickly complete the cooling work, and avoiding the appearance of surface oxidation and dullness. At the same time, during the flipping process, the centrifugal basket can also be rotated to accelerate the discharging of the galvanized parts and avoid the situation of the galvanized parts getting stuck.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figure 1-7 , the present invention provides a technical solution: a flip - type drum centrifuge, including a support 1, a central axis 2 is rotatably connected to the support 1, and both sides of the central axis 2 are connected to the support 1 through bearings and bearing seats. A housing 3 is rotatably connected to the outer side of the middle part of the central axis 2, and bearings and bearing seats are also installed between the housing 3 and the central axis 2. A centrifugal drum 4 is rotatably connected to one side of the housing 3, a zinc pot is arranged directly below the centrifugal drum 4, and a large gear 9 is installed on the outer side of the upper part of the centrifugal drum 4. The centrifugal drum 4 is a cylindrical shape with openings at both upper and lower ends, and a horn - shaped frame body for restricting the position of the centrifugal basket 11 is arranged at the upper part, and bearings are installed between the centrifugal drum 4 and the housing 3.

[0027] A transmission mechanism 8 for driving the centrifugal drum 4 to rotate is installed between the central axis 2 and the large gear 9, a flipping mechanism 6 for discharging centrifuged parts is installed on one side of the housing 3, a cooling pool is arranged on the flipping path of the centrifugal drum 4 and the centrifugal basket 11, and the central axis of the flipping center of the flipping mechanism 6 is coaxially arranged with the central axis of the central axis 2.

[0028] Such as Figure 3 and Figure 4As shown in the figure: The transmission mechanism 8 includes a plurality of rotating shafts 82; the plurality of rotating shafts 82 are installed inside the housing 3, and transmission gears 84 are installed on each of the plurality of rotating shafts 82. The transmission gears 84 are meshed and connected with the large gear 9; a second bevel gear 83 is installed on one rotating shaft 82, and a first bevel gear 81 is installed on the middle shaft 2. The second bevel gear 83 and the first bevel gear 81 are meshed and connected; through the above settings, the plurality of rotating shafts 82 are vertically rotatably connected inside the housing 3. Transmission gears 84 are installed above each rotating shaft 82. These transmission gears 84 are meshed with each other in sequence and are also meshed and connected with the large gear 9. A second bevel gear 83 is also installed below the rotating shaft 82 on the side close to the middle shaft 2. At the same time, a first bevel gear 81 is installed on the outer side of the middle shaft 2 inside the housing 3. The meshing connection between the first bevel gear 81 and the second bevel gear 83 can drive the rotating shaft 82 to rotate, and further drive the centrifugal drum 4 to rotate through the large gear 9.

[0029] As Figure 2 and Figure 3 shown in the figure: The tipping mechanism 6 includes a sleeve 61; the sleeve 61 is installed on one side of the housing 3. A tipping gear 62 is installed on one side of the sleeve 61. The sleeve 61 and the tipping gear 62 are rotatably connected to the outside of the middle shaft 2. A tipping rack 63 is meshed with the tipping gear 62. One end of the tipping rack 63 is installed with a tipping drive cylinder 64. The tipping drive cylinder 64 is installed on the bracket 1; through the above settings, the sleeve 61, the tipping gear 62 and the housing 3 are fixedly connected, and the tipping gear 62 and the sleeve 61 are located outside the middle shaft 2. In this way, when the tipping drive cylinder 64 drives the tipping rack 63 to move, the housing 3 can be driven to tip around the middle shaft 2 through the tipping gear 62 and the sleeve 61, so as to pour the centrifugal part into the cooling pool for rapid cooling work.

[0030] As Figure 5 、 Figure 6 and Figure 7 shown in the figure: The centrifugal drum 4 is provided with a centrifugal basket 11. A second driving block 13 is installed on the outside of the centrifugal basket 11, and a first driving block 10 is installed on the inside of the centrifugal drum 4; through the above settings, a frame adapted to the horn-shaped frame on the centrifugal drum 4 is provided above the centrifugal basket 11, which can support the centrifugal basket 11 and avoid the situation of falling. After the centrifugal basket 11 is placed inside the centrifugal drum 4, the centrifugal drum 4 can drive the centrifugal basket 11 to rotate through the first driving block 10 and the second driving block 13, and then complete the centrifugation work of the centrifugal part inside the centrifugal basket 11.

[0031] As Figure 5As shown in the figure: A retaining wall 12 for blocking the zinc skin after centrifugation is installed below one side of the housing 3; through the above settings, a zinc pot is provided directly below the centrifugal drum 4 and the centrifugal basket 11. After the centrifuged zinc skin is blocked by the retaining wall 12, it will fall into the internal zinc pot below, and thus the direct recovery of the zinc skin can be quickly completed.

[0032] As Figure 2 shown in the figure: A protective cover plate 7 is slidably connected to one side of the bracket 1, and a cover plate driving cylinder 14 for driving the movement of the protective cover plate 7 is installed on one side of the protective cover plate 7; through the above settings, the cover plate driving cylinder 14 can drive the protective cover plate 7 to move. When centrifuging, the protective cover plate 7 is moved directly above the centrifugal basket 11 to provide safety protection during centrifugal rotation.

[0033] As Figure 1 shown in the figure: A driving wheel 5 is installed on one side of the central shaft 2, and a driving motor, a belt pulley, a belt, and a clutch brake for driving the driving wheel 5 to rotate are installed inside the bracket 1; through the above settings, the central shaft 2 can be driven to rotate more conveniently and quickly.

[0034] Working principle: The centrifugal basket 11 is placed inside the centrifugal drum 4, and the protective cover plate 7 is driven to move directly above the centrifugal basket 11. Then, the driving wheel 5 is driven to rotate through the driving motor, the belt pulley, the belt, and the clutch brake. The driving wheel 5 drives the central shaft 2 to rotate. The central shaft 2 drives the rotating shaft 82 to rotate through the first bevel gear 81 and the second bevel gear 83. The rotating shaft 82 drives the transmission gear 84 and the large gear 9 to rotate. Then, the centrifugal drum 4 can be rotated through the large gear 9. The centrifugal drum 4 can drive the centrifugal basket 11 to rotate through the first driving block 10 and the second driving block 13, thereby completing the centrifugation work of the galvanized parts, enabling the zinc skin to directly fall into the zinc pot below to complete the recovery work.

[0035] After centrifugation is completed, the protective cover plate 7 is opened. At this time, the flipping driving cylinder 64 drives the flipping rack 63 to move. The flipping rack 63 can drive the housing 3 to drive the centrifugal basket 11 to rotate around the central shaft 2 through the flipping gear 62 and the sleeve 61, so that the centrifuged parts can be poured into the cooling pool on the flipping path for rapid cooling, avoiding the situation that the surface of the centrifuged parts becomes dull due to the too long time for handling and transferring the centrifuged parts after centrifugation.

[0036] Meanwhile, during the flipping process, the second bevel gear 83 will move along the outer side of the housing 3 around the central axis 2. Then, since the central axis 2 is restricted from rotating when components such as the drive motor are not started, the first bevel gear 81 fixedly connected to the central axis 2 cannot rotate either. As a result, when the second bevel gear 83 moves along the outer side of the housing 3 around the central axis 2, it will also rotate itself. By the rotation of the second bevel gear 83 during the flipping process, the centrifugal drum 4 and the centrifugal basket 11 can be rotated to a certain extent to play a role in rapid discharging, and it can also avoid the situation where galvanized parts are stuck to a certain extent.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
