Description

Technical Field

[0001] This application relates to the technical field of casting, and in particular to a mechanical incubator. Background Technology

[0002] Currently, in the foundry industry, during ladle casting, the molten iron poured into the mold needs to undergo in-flow inoculation. Existing in-flow inoculants have a simple structure, requiring manual hand-held inoculation or inoculation controlled by a solenoid valve. Hand-held inoculation is inconvenient and prone to burns, while delayed solenoid valve opening can easily lead to uneven inoculation.

[0003] Regarding the aforementioned technologies, the inventor believes that a mechanical, flow-fed incubator is needed that can be used and opened at any time without causing burns, and that produces more uniform incubation. Utility Model Content

[0004] The purpose of this application is to provide a mechanical incubator that flows with the flow to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a mechanical incubator using the following technical solution:

[0006] A mechanical incubator includes an incubator body, a cover plate at the top of the incubator body, and a discharge port at the bottom of the incubator body. The incubator body contains a filter screen, and a discharge mechanism is located at the bottom of the filter screen. The discharge mechanism includes a discharge baffle, a through hole, a stop block, a first connecting rod, a fixing block, a second connecting rod, a spring, a third connecting rod, a support block, a pull wire, and a handle. The filter screen has a discharge baffle fixed to the inner wall of the incubator body at its bottom. The discharge baffle has a through hole at its center, and the bottom of the through hole contacts a stop block. A first connecting rod is fixed to the side, and a fixing block is fixed to the end of the first connecting rod away from the stop block. A second connecting rod is slidably arranged inside the first connecting rod and the fixing block. A spring is sleeved on the second connecting rod. A third connecting rod is connected to the end of the second connecting rod away from the fixing block. Support blocks are fixed to the end of the third connecting rod away from the second connecting rod and the outer side of the first connecting rod. Pull-out steel wires are fixed to both sides of the fixing block. A handle is fixed to the other end of the pull-out steel wires. Multiple support rods are arranged around the top of the feeding baffle, and a support frame is fixed to the top of the support rods.

[0007] By adopting the above technical solution, squeezing the handle pulls the steel wire, which in turn moves the fixed block on the second connecting rod, compressing the spring and causing the stop block to leave the through hole, thus facilitating material feeding. By controlling the force of squeezing the handle, the size of the opening of the through hole can be controlled, making it easier to adjust the flow rate of the inoculant and making the inoculant feeding more uniform. The support frame can partially block the inoculant, preventing the inoculant from being squeezed at the through hole and causing uneven or untimely feeding.

[0008] Preferably, the feeding baffle is configured to be concave in the middle and convex around the edges.

[0009] By adopting the above technical solution, it is convenient for materials to enter the through hole.

[0010] Preferably, one end of the spring is fixedly connected to the fixing block, and the other end is fixedly connected to the third connecting rod, and the support block is fixedly installed at the bottom of the feeding baffle.

[0011] By adopting the above technical solution, the spring is compressed when the fixed block is pulled.

[0012] Preferably, the bottom of the discharge baffle is provided with a pushing mechanism, which includes a rotating ring, a push rod, a first wedge block, a limiting groove, a second wedge block, and a pull rod. The discharge baffle is provided with a ring-shaped rotating ring that slides through it. The rotating ring is slidably connected to the discharge baffle. The bottom of the rotating ring is hinged with a push rod. The bottom of the push rod is fixed with a first wedge block. The first wedge block is slidably disposed in the limiting groove. The bottom of the first wedge block is fitted with a second wedge block. A pull rod is fixed to one side of the second wedge block.

[0013] By adopting the above technical solution, when the pull wire is pulled, the pull rod moves, causing the second wedge block to push the first wedge block, which in turn causes the push rod to push the rotating ring, thereby causing the rotating ring to rotate to a certain position. When the second wedge block returns to its original position, the first wedge block, under the action of gravity, causes the rotating ring to return to its original position.

[0014] Preferably, the top of the limiting chute is fixedly connected to the discharge baffle, and the cross-section of the rotating ring is set in a cross shape and fits into the discharge baffle.

[0015] By adopting the above technical solution, the first wedge block can only move up and down.

[0016] Preferably, the pull rod passes through the support block and is fixedly connected to the fixing block, and the top of the swivel is fixedly connected to the support rod.

[0017] By adopting the above technical solution, the rotating ring drives the support rod to rotate when it rotates, which in turn drives the support frame to rotate, making it easier to loosen the accumulated inoculant and accelerate its downward flow.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The feeding mechanism facilitates the pulling of the steel wire when the handle is squeezed, which in turn moves the fixed block on the second connecting rod, compressing the spring and causing the stop block to leave the through hole, thus facilitating feeding. By controlling the force of squeezing the handle, the size of the opening of the through hole can be controlled, making it easier to adjust the flow rate of the inoculant and making the inoculant more uniform. The support frame can partially block the inoculant, preventing the inoculant from being squeezed at the through hole and causing uneven or untimely feeding.

[0020] 2. By setting up the pushing mechanism, it is beneficial to drive the pull rod to move when the pull wire is pulled, so that the second wedge block pushes the first wedge block, so that the push rod pushes the rotating ring, and then drives the rotating ring to rotate a certain position. The rotating ring drives the support rod to rotate, and then drives the support frame to rotate, which facilitates the loosening of the accumulated inoculant and accelerates the downward flow of the inoculant. When the second wedge block returns to its position, the first wedge block drives the rotating ring back to its original position under the action of gravity. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a mechanical incubator that works in conjunction with the flow of fluids, with reference to... Figure 1-5 The device includes an incubator body 1, a cover plate 11 at the top of the incubator body 1, and a discharge port 12 at the bottom of the incubator body 1. The incubator body 1 has a filter screen 2 inside to filter incubator particles and prevent larger impurities from entering. The bottom of the filter screen 2 has a discharge mechanism 3, which includes a discharge baffle 31, a through hole 32, a stop block 33, a first connecting rod 34, a fixing block 35, a second connecting rod 36, a spring 37, a third connecting rod 38, a support block 39, a pull-out steel wire 310, and a handle 311. The filter screen 2... A discharge baffle 31, fixed to the inner wall of the incubator body 1, is provided at the bottom. The discharge baffle 31 is designed to be concave in the middle and convex around the edges, facilitating the accumulation of inoculant at the center of the discharge baffle 31 and thus facilitating the passage of inoculant through the through hole 32. The discharge baffle 31 has a through hole 32 at its center, and a stop block 33 is provided at the bottom of the through hole 32. A first connecting rod 34 is fixed to one side of the stop block 33, and a fixing block 35 is fixed to the end of the first connecting rod 34 away from the stop block 33. A second connecting rod 36 is slidably arranged within the first connecting rod 34 and the fixing block 35. A spring 37 is fitted over the connecting rod 36. One end of the spring 37 is fixedly connected to the fixing block 35, and the other end is fixedly connected to the third connecting rod 38. The support block 39 is fixedly installed at the bottom of the discharge baffle 31. The end of the second connecting rod 36 away from the fixing block 35 is connected to the third connecting rod 38. The end of the third connecting rod 38 away from the second connecting rod 36 and the outer side of the first connecting rod 34 are both fixed with support blocks 39. Pull-out steel wires 310 are fixed on both sides of the fixing block 35. A handle 311 is fixed to the other end of the pull-out steel wire 310. When the handle 311 is moved, the pull wire 310 is pulled, which causes the fixed block 35 to move on the second connecting rod 36, compressing the spring 37 and causing the stop block 33 to leave the through hole 32. The force of the handle 311 is controlled, thereby controlling the size of the opening of the through hole 32, which facilitates the adjustment of the inoculant flow rate and makes the inoculant more uniform. The top of the feeding baffle 31 is surrounded by multiple support rods 4, and the top of the support rods 4 is fixed with a support frame 5. The support frame 5 can partially block the inoculant and avoid the inoculant being squeezed at the through hole 32, which would cause uneven or untimely feeding.

[0029] Reference Figure 3-5The bottom of the discharge baffle 31 is provided with a pushing mechanism 6. The pushing mechanism 6 includes a rotating ring 61, a push rod 62, a first wedge block 63, a limiting groove 64, a second wedge block 65, and a pull rod 66. A ring-shaped rotating ring 61 is provided through the discharge baffle 31, and the rotating ring 61 is slidably connected to the discharge baffle 31. The bottom of the rotating ring 61 is hinged to the push rod 62, and the bottom of the push rod 62 is fixed with the first wedge block 63. The first wedge block 63 is slidably disposed within the limiting groove 64, allowing the first wedge block 63 to move upwards or downwards. The bottom of the first wedge block 63 is fitted with the second wedge block 65, and a pull rod 66 is fixed to one side of the second wedge block 65. The top of the limiting groove 64 is fixedly connected to the discharge baffle 31. The cross-section of the rotating ring 61 is set in a cross shape and fits into the discharge baffle 31 to easily lock the discharge baffle 31 and support it. The pull rod 66 passes through the support block 39 and is fixedly connected to the fixing block 35. The top of the rotating ring 61 is fixedly connected to the support rod 4. When the pull wire 310 is pulled, the pull rod 66 moves, causing the second wedge block 65 to push the first wedge block 63, which causes the push rod 62 to push the rotating ring 61, thereby causing the rotating ring 61 to rotate to a certain position. The rotating ring 61 drives the support rod 4 to rotate, which in turn drives the support frame 5 to rotate, which facilitates the loosening of the accumulated inoculant and accelerates the downward flow of the inoculant. When the second wedge block 65 returns to its original position, the first wedge block 63 drives the rotating ring 61 back to its original position under the action of gravity.

[0030] The implementation principle of a mechanical incubator according to an embodiment of this application is as follows:

[0031] When using the device, a suitable inoculant is added to the inoculant body of the molten iron measuring tank. The inoculant is filtered through the filter screen 2. When pouring, the operator manually squeezes the handle 311 according to the flow rate of the molten iron, which pulls the pull wire 310, thereby moving the fixed block 35 on the second connecting rod 36. This compresses the spring 37, causing the stop block 33 to move away from the through hole 32, and the inoculant is added into the molten iron. By controlling the force of squeezing the handle 311, the opening size of the through hole 32 can be controlled, making it easy to adjust the flow rate of the inoculant and making the inoculant more uniform. The support frame 5 can guide the inoculant... The obstruction of the flow section prevents the inoculant from being squeezed into the through hole 32, causing uneven or untimely feeding. The pull rod 66 at the bottom of the fixed block 35 moves, causing the second wedge block 65 to push the first wedge block 63, which in turn causes the push rod 62 to push the rotating ring 61, thereby causing the rotating ring 61 to rotate to a certain position. The rotating ring 61 drives the support rod 4 to rotate, which in turn drives the support frame 5 to rotate, making it easier to loosen the accumulated inoculant and accelerate the downward flow of the inoculant. When the handle 311 is released, the second wedge block 65 returns to its original position, and the first wedge block 63, under the action of gravity, drives the rotating ring 61 back to its original position.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
