Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing centrifugal equipment, in particular to a bolt galvanizing centrifugal device. Background Art

[0002] Bolts are generally made of iron. In order to improve the corrosion resistance of bolts, they will be galvanized. When the galvanized layer on the outside of the bolts is still in a molten state, they are placed in a centrifuge to remove excess zinc liquid to ensure that the surface of the bolts is smooth after galvanizing.

[0003] The centrifugal device is driven to rotate by a motor, and the motor is located below the turntable. The cage on the top of the turntable is bolted, and the bolts of the disc and the top cage throw out excess zinc liquid, which will be thrown to the inside of the outer annular cylinder and move down along the inner wall of the outer annular cylinder. Since the motor is located on the inside of the annular cylinder, the power cord of the motor passes under the annular cylinder, and the zinc liquid in the annular cylinder will flow to the power cord of the motor. Long-term contact of high-temperature zinc liquid with the motor power cord will shorten the life of the motor power cord. Summary of the invention

[0004] The disclosed embodiment relates to a bolt galvanizing centrifugal device, in which the external drive gear and the drive motor are both located outside the inner centrifugal cage instead of vertically below it, thereby avoiding the situation in which the motor of the existing centrifugal device is located below, and the power cord of the motor will be thrown out and contacted with zinc liquid when passing through the inner centrifugal cage and below the outer liquid blocking cylinder. Long-term contact with high-temperature zinc liquid shortens the life of the power cord of the motor.

[0005] In a first aspect of the present disclosure, a bolt galvanizing centrifugal device is provided, which specifically includes: an inner centrifugal cage, an outer liquid blocking cylinder and a lower ring frame, wherein the outer liquid blocking cylinder is arranged on the outer side of the inner centrifugal cage, the lower ring frame is arranged below the outer liquid blocking cylinder, an outer gear ring is fixed to the outer side of the upper part of the inner centrifugal cage, and a convex sliding block is fixed to the bottom of the outer gear ring.

[0006] In at least some embodiments, the outer annular array on the outside of the outer liquid-blocking cylinder has an external connecting block, the outer liquid-blocking cylinder is through-connected from top to bottom, the lower part of the external connecting block is fixedly connected to a lower supporting spring, the lower end of the lower supporting spring is fixed to the lower pillar, the external connecting block and the outer sliding column axially penetrate and slide, and the top end of the outer sliding column is rotated with an upper limit wheel.

[0007] In at least some embodiments, the lower end of the outer sliding column is fixedly connected to the lower support column, the lower support column is fixedly connected to the lower ring frame, and the upper limit wheel is meshed with the outer gear ring.

[0008] In at least some embodiments, a convex sliding block is fixed to the top of the outer liquid retaining tube, and when the convex sliding block of the outer liquid retaining tube and the convex sliding block at the bottom of the outer gear ring slide, the outer liquid retaining tube moves downward and away from the outer gear ring.

[0009] In at least some embodiments, a middle cross bracket is fixed at the center of the lower ring frame, a middle turntable rotates at the center of the middle cross bracket, drive motors are fixed on both sides of the lower ring frame, a drive motor main shaft and an external drive gear are fixed on one side of the lower ring frame, a drive motor main shaft and a tail end of the upper cover plate are fixed on the other side of the lower ring frame, a lower cover plate bracket is fixed on the outer side of the lower ring frame, and the diameter of the lower ring frame is larger than the outer liquid blocking cylinder.

[0010] In at least some embodiments, the top of the middle turntable fits with the bottom of the inner centrifugal cage, the top of the lower cover bracket fits with the upper cover floor in a sliding manner, and the lower cover bracket provides auxiliary support for the upper cover when it is rotated outward to open.

[0011] In at least some embodiments, the upper cover plate is located above the inner centrifugal cage, the outer gear ring is meshed with the outer drive gear, the outer drive gear meshes with the outer gear ring to drive the inner centrifugal cage to rotate, and the outer drive gear and the drive motor are both located outside the inner centrifugal cage.

[0012] The utility model provides a centrifugal device for galvanizing bolts, which has the following beneficial effects:

[0013] The outer drive gear meshes with the outer gear ring to drive the inner centrifugal cage to rotate. The outer drive gear and the drive motor are both located outside the inner centrifugal cage instead of vertically below it, so as to avoid the situation in which the motor of the existing centrifugal device is located below and the power cord of the motor is thrown out and contacts with zinc liquid when passing through the inner centrifugal cage and below the outer liquid blocking cylinder. The long-term contact with high-temperature zinc liquid shortens the life of the power cord of the motor.

[0014] The outer liquid retaining cylinder moves and vibrates in the vertical direction through the sliding of the convex sliding block of the outer liquid retaining cylinder and the convex sliding block at the bottom of the outer gear ring. The vibration of the outer liquid retaining cylinder accelerates the falling and separation of the zinc liquid attached inside, reduces the amount of zinc liquid attached inside the outer liquid retaining cylinder, reduces the burden of later cleaning inside the outer liquid retaining cylinder, and prolongs the service life of the outer liquid retaining cylinder.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] The present embodiment proposes a bolt galvanized centrifugal device, comprising: an inner centrifugal cage 1, an outer liquid retaining cylinder 2 and a lower ring frame 3, wherein an outer gear ring 101 is fixed to the outer side of the upper part of the inner centrifugal cage 1, a convex slider 102 is fixed to the bottom of the outer gear ring 101, an outer liquid retaining cylinder 2 is arranged on the outer side of the inner centrifugal cage 1, an outer connecting block 201 is arranged in an annular array on the outer side of the outer liquid retaining cylinder 2, the outer liquid retaining cylinder 2 is through-connected from top to bottom, a lower supporting spring 202 is fixedly connected to the lower part of the outer connecting block 201, the lower end of the lower supporting spring 202 is fixed to a lower pillar 204, the outer connecting block 201 and an outer sliding column 203 are axially penetrated and slidable, an upper limit wheel 205 is rotated at the top of the outer sliding column 203, the lower end of the outer sliding column 203 is fixedly connected to the lower pillar 204, the lower pillar 204 is fixedly connected to the lower ring frame 3, the upper limit wheel 205 is meshed with the outer gear ring 101, and the upper limit wheel 205 of the annular array is engaged with the outer gear ring 101. The position of outer gear ring 101 is restricted, ensure that outer gear ring 101 is in the center position of outer liquid retaining cylinder 2, lower ring frame 3 is provided below outer liquid retaining cylinder 2, lower ring frame 3 is in contact with the ground, middle cross bracket 301 is fixed at the center of lower ring frame 3, middle cross bracket 301 center is rotated with middle turntable 302, driving motor 304 is fixed on both sides of lower ring frame 3, driving motor 304 main shaft and outer driving gear 303 are fixed on one side of lower ring frame 3, driving motor 304 main shaft and upper cover plate 305 tail ends are fixed on the other side of lower ring frame 3, lower cover plate bracket 306 is fixed on the outside of lower ring frame 3, the diameter of lower ring frame 3 is larger than outer liquid retaining cylinder 2, middle turntable 302 top and inner centrifugal cage 1 bottom are fitted, lower cover plate bracket 306 top and upper cover plate 305 ground sliding fit, lower cover plate bracket 306 supports auxiliary when upper cover plate 305 is rotated outwards and opened.

[0031] In the disclosed embodiment, a convex sliding block 102 is fixed on the top of the outer liquid-blocking cylinder 2. When the convex sliding block 102 of the outer liquid-blocking cylinder 2 and the convex sliding block 102 at the bottom of the outer toothed ring 101 slide, the outer liquid-blocking cylinder 2 moves downward away from the outer toothed ring 101, and the reciprocating vertical vibration of the outer liquid-blocking cylinder 2 accelerates the falling and detachment of the zinc liquid attached inside, reduces the amount of zinc liquid attached inside the outer liquid-blocking cylinder 2, and reduces the burden of cleaning the zinc liquid inside the outer liquid-blocking cylinder 2 in the later stage.

[0032] In the disclosed embodiment, the upper cover plate 305 is located above the inner centrifugal cage 1, the outer gear ring 101 is meshed with the outer drive gear 303, the outer drive gear 303 is meshed with the outer gear ring 101 to drive the inner centrifugal cage 1 to rotate, the outer drive gear 303 and the drive motor 304 are both located outside the inner centrifugal cage 1, and the problem of the existing centrifugal device motor being located at the bottom, the motor power cord being in contact with the zinc liquid flowing down the outer liquid blocking cylinder 2, and the long-term contact of the high-temperature zinc liquid with the motor power cord shortening the life of the motor power cord will not occur.

[0033] Embodiment 2, on the basis of embodiment 1, a turntable which rotates in a circular direction is arranged at the front end of the upper cover plate 305, the turntable at the front end of the upper cover plate 305 contacts the top of the inner centrifugal cage 1 and rotates synchronously with the inner centrifugal cage 1, and the upper cover plate 305 fixes the vertical position of the inner centrifugal cage 1 during its rotation, so as to avoid the situation in which the inner centrifugal cage 1 moves in the vertical direction during its circular rotation and fails to maintain meshing with the external driving gear 303.

[0034] The working principle of this embodiment is as follows: the inner centrifugal cage 1 with a mesh structure is immersed in zinc liquid and then the bolts are placed. The mesh holes of the inner centrifugal cage 1 with a mesh structure facilitate the passage of the zinc liquid after being thrown out. The upper cover plate 305 rotates to the top of the inner centrifugal cage 1 to seal the upper part. The drive motor 304 starts to drive the outer drive gear 303 to rotate. The outer drive gear 303 engages with the outer gear ring 101 to drive the inner centrifugal cage 1 to rotate. The inner centrifugal cage 1 is horizontally limited by the outer upper limit wheel 205. The bolts inside the inner centrifugal cage 1 rotate synchronously to throw out and separate the excess zinc liquid. The excess zinc liquid is thrown to the outer liquid retaining cylinder 2. The outer liquid retaining cylinder 2 will separate the excess zinc liquid and limit the inner side to prevent the zinc liquid from spilling everywhere. In the case of falling, the zinc liquid inside the outer liquid retaining cylinder 2 flows downward through the interval between the outer liquid retaining cylinder 2 and the lower ring frame 3, and the excess zinc liquid is collected, recycled and reused in a unified manner. The inner centrifugal cage 1 can be vertically taken out through the protruding outer gear ring 101 to perform the replacement operation of the inner centrifugal cage 1. The outer driving gear 303 and the driving motor 304 are both located outside the inner centrifugal cage 1 instead of vertically below, which avoids the existing centrifugal device motor being located below, and the motor power line passing through the inner centrifugal cage 1 and the outer liquid retaining cylinder 2 will be thrown out and contacted with the zinc liquid. The long-term contact of the high-temperature zinc liquid with the power line of the motor will shorten the life of the power line of the motor, and avoid the situation where the zinc liquid attached to the power line is regularly cleaned, which increases the cleaning burden of personnel;

[0035] The outer gear ring 101 rotates synchronously with the inner centrifugal cage 1. When the convex slider 102 of the outer liquid retaining cylinder 2 and the convex slider 102 at the bottom of the outer gear ring 101 slide, the outer liquid retaining cylinder 2 moves and vibrates in the vertical direction. The outer connecting block 201 of the outer liquid retaining cylinder 2 moves downward along the outer sliding column 203 synchronously to compress the lower supporting spring 202. After the convex slider 102 of the outer liquid retaining cylinder 2 and the convex slider 102 at the bottom of the outer gear ring 101 are separated, the lower supporting spring 202 supports the outer liquid retaining cylinder 2 to move up and reset. The reciprocating vertical vibration of the outer liquid retaining cylinder 2 accelerates the falling and separation of the zinc liquid attached inside, reduces the amount of zinc liquid attached inside the outer liquid retaining cylinder 2, reduces the cleaning burden of the zinc liquid inside the outer liquid retaining cylinder 2 in the later stage, and prolongs the service life of the outer liquid retaining cylinder 2.
