Description

Technical Field

[0001] The invention belongs to the technical field of ingot processing, and in particular relates to a transfer device for recycling molten aluminum. Background Art

[0002] Aluminum slag is produced when molten aluminum is cast. The aluminum slag produced can be processed by a ash roaster to recover part of the molten aluminum, and then the recovered molten aluminum is transported back to the melting furnace for casting, which can improve resource utilization. In the prior art, the hopper is usually driven directly by a forklift for transportation. However, the forklift will shake during the transportation process, especially the inertia when turning, which can easily cause the molten aluminum to overflow or splash out. The temperature of the molten aluminum is relatively high. If it splashes on the staff, it is very easy to cause injury. Even if it overflows on the ground, it will cause waste and is difficult to clean. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a transfer device for recovering molten aluminum to solve the problem that shaking may occur during forklift transportation, especially the inertia effect when turning, which may easily cause the molten aluminum to overflow or splash out.

[0004] According to an embodiment of the present invention, the present invention adopts the following technical solution:

[0005] The transfer device for recycling aluminum liquid comprises a transfer vehicle, a charging assembly installed on the transfer vehicle, and a splash-proof assembly; the charging assembly comprises a first slide plate connected to the transfer vehicle in a vertical sliding manner, a charging rod connected to the first slide plate in a horizontal sliding manner, and a charging member installed on the charging rod, the charging member comprises a bottom plate detachably connected to the charging rod and a hopper hinged on the bottom plate, and an opening is arranged at the upper end of the hopper; a limiting plate is hingedly connected to a side of the hopper facing away from the first slide plate, the upper end of the limiting plate protrudes from the upper side of the hopper, a slider is slidably connected to the side wall of the hopper, a connecting rod is hingedly connected between the slider and the limiting plate, and a connecting rod is hinged between the slider and the side wall of the hopper A spring is connected; the splash-proof assembly includes a second slide plate vertically slidably connected to the transfer vehicle, a first telescopic rod detachably connected to the second slide plate, a mounting plate installed at the end of the first telescopic rod, a second telescopic rod installed on the mounting plate, and a cover body installed at the end of the second telescopic rod, the telescopic directions of the first telescopic rod and the second telescopic rod are parallel to the sliding direction of the loading rod, the cover body is arranged above the hopper and is used to cover the closed opening; a push rod is hinged on the cover body or the second telescopic rod, a support rod is fixed on the mounting plate, the middle or upper part of the push rod is hinged on the support rod, and the push rod is used to push the slider to slide toward the limit plate.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] By sliding the first slide plate, the height of the charging piece is adjusted so that the position of the charging piece is adapted to the height of the ash roasting machine or the melting and casting furnace, which is convenient for loading or discharging. By sliding the charging rod, the distance between the charging piece and the ash roasting machine or the melting and casting furnace is adjusted. By sliding the second slide plate, the cover body can be driven to be set on the hopper, or to be located above the hopper and open the hopper. By telescoping the first telescopic rod, the position of the cover body is adjusted so that the cover body is located directly above the hopper or staggered from the opening of the hopper, so that the molten aluminum can enter the hopper. By telescoping the second telescopic rod, when the cover body is set on the hopper, the position of the cover body can be fine-tuned so that the opening of the hopper is partially opened to facilitate the discharging of the molten aluminum. In this scheme, the design of the cover body avoids the problem of molten aluminum overflowing or splashing during transportation, and when discharging, by controlling the degree of opening of the hopper, the problem of large amounts of molten aluminum directly pouring into the melting and casting furnace to cause splashing is also avoided.

[0008] When the cover is closed on the hopper, the limit plate is in contact with the side wall of the hopper, which has a certain limit effect on the end of the cover, and the hopper can be completely covered by observing whether the cover and the limit plate are in contact. When the second telescopic rod contracts and drives the cover to open the hopper, the cover or the second telescopic rod drives the push rod to swing, and the push rod pushes the slider to slide, causing the limit plate to deflect. After the limit plate deflects, it can be hooked at the opening of the melting furnace. When the molten aluminum enters the melting furnace, the limit plate plays a certain guiding role.

[0009] Furthermore, a displacement sensor for detecting the sliding of the slider is installed on the side wall of the hopper.

[0010] Furthermore, a third telescopic rod is hinged between the bottom plate and the hopper.

[0011] Furthermore, an inclined guide surface is provided on a side of the inner wall of the hopper facing away from the first slide plate, and a lower end of the guide surface is inclined toward the direction of the first slide plate.

[0012] Furthermore, a liquid outlet pipe is fixed in the hopper, and the liquid outlet pipe includes a first section fixed on the bottom of the hopper, a second section fixed on the guide surface, and a third section connected between the first section and the second section. The inner diameters of the first section and the second section are both larger than the inner diameter of the third section, and a liquid inlet hole is opened on the third section.

[0013] Furthermore, the liquid inlet hole is arranged obliquely, and one end of the liquid inlet hole located in the third section is inclined toward the guide surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0019] like Figure 1 As shown, the transfer device for aluminum liquid recovery includes a transfer vehicle 1, a loading assembly and a splash-proof assembly installed on the transfer vehicle 1. The transfer vehicle 1 can use a forklift in the prior art or other carts in the prior art. A mounting frame 2 is fixed on the transfer vehicle 1, and the loading assembly and the splash-proof assembly are both installed on the mounting frame 2.

[0020] The charging assembly includes a first slide plate 3 connected to the transfer vehicle 1 in a vertical sliding manner, a charging rod 4 connected to the first slide plate 3 in a horizontal sliding manner, and a charging piece installed on the charging rod 4. Specifically, the first slide plate 3 is connected to the mounting frame 2 in a sliding manner, and a cylinder for driving the first slide plate 3 to slide is installed on the mounting frame 2. A cylinder for driving the charging rod 4 to slide is installed on the first slide plate 3. In the actual design process, the charging rod 4 can also directly select an electric telescopic rod fixedly installed on the first slide plate 3. The height of the charging piece is adjusted by sliding the first slide plate 3, so that the position of the charging piece is adapted to the height of the ash roasting machine or the melting and casting furnace, and the distance between the charging piece and the ash roasting machine or the melting and casting furnace is adjusted by sliding the charging rod 4.

[0021] The loading part includes a base plate 5 detachably connected to the loading rod 4 and a hopper 6 hinged on the base plate 5. Specifically, the bottom of the end of the hopper 6 facing away from the first slide plate 3 is hinged on the base plate 5. The base plate 5 is provided with a socket for inserting the loading rod 4. The side wall of the base plate 5 is threadedly connected with a screw rod. The end of the screw rod extends through the socket and is used to abut against the loading rod 4. Through the setting of the screw rod, the friction between the base plate 5 and the loading rod 4 is increased, and the movement of the base plate 5 on the loading rod 4 is reduced to a certain extent. A third telescopic rod 7 is hinged between the base plate 5 and the hopper 6. Specifically, a connecting block 8 is fixed to the upper part of the side wall of the hopper 6. One end of the third telescopic rod 7 is hinged on the connecting block 8, and the other end of the third telescopic rod 7 is hinged on the base plate 5. The third telescopic rod 7 is an electric telescopic rod in the prior art. The deflection of the hopper 6 relative to the base plate 5 is adjusted by the extension and retraction of the third telescopic rod 7. When the hopper 6 is in a horizontal state, it is used for adding or transporting materials. When the hopper 6 is tilted relative to the base plate 5, it is used for discharging materials.

[0022] An opening is provided at the upper end of the hopper 6, and the hopper 6 is used to store molten aluminum. A limit plate 11 is hingedly connected to the side of the hopper 6 facing away from the first slide plate 3. When the limit plate 11 is in contact with the side wall of the hopper 6, the upper end of the limit plate 11 protrudes from the upper side of the hopper 6. A slider 10 is slidably connected to the side wall of the hopper 6, and a connecting rod 9 is hinged between the slider 10 and the limit plate 11. A spring (not shown in the figure) is connected between the slider 10 and the side wall of the hopper 6. The slider 10 slides through the connecting rod 9 to drive the limit plate 11 to deflect, so that the limit plate 11 has two states: in contact with the side wall of the hopper 6 and deflected relative to the side wall of the hopper 6.

[0023] The splash-proof assembly includes a second slide plate 18 vertically slidably connected to the transfer vehicle 1, a first telescopic rod 17 detachably connected to the second slide plate 18, a mounting plate 16 mounted at the end of the first telescopic rod 17, a second telescopic rod 15 mounted on the mounting plate 16, and a cover body 12 mounted at the end of the second telescopic rod 15. Specifically, the second slide plate 18 is slidably connected to the mounting frame 2, and a cylinder for driving the second slide plate 18 to slide is installed on the mounting frame 2. The telescopic directions of the first telescopic rod 17 and the second telescopic rod 15 are parallel to the sliding direction of the loading rod 4. The first telescopic rod 17 and the second telescopic rod 15 are both electric telescopic rods in the prior art. The first telescopic rod 17 is bolted to the first slide plate 3, the mounting plate 16 and the first telescopic rod 17 are bolted, and the second telescopic rod 15 is fixed to the mounting plate 16. By detachably connecting, when the cover body 12 is not needed, the first telescopic rod 17, the mounting plate 16, the second telescopic rod 15, and the cover body 12 can be removed to reduce the load of the transfer vehicle 1.

[0024] The cover 12 is disposed above the hopper 6 and is used to cover the closed opening. The sliding of the second slide plate 18 can drive the cover 12 to cover the hopper 6, or to be located above the hopper 6 and open the hopper 6. The position of the cover 12 is adjusted by the extension of the first telescopic rod 17, so that the cover 12 is located directly above the hopper 6 or staggered from the opening of the hopper 6, so that the molten aluminum can enter the hopper 6. By the extension of the second telescopic rod 15, when the cover 12 is covered on the hopper 6, the position of the cover 12 can be finely adjusted so that the opening of the hopper 6 is partially opened, so that the molten aluminum can be discharged.

[0025] A push rod 13 is hinged on the cover body 12 or the second telescopic rod 15. In this embodiment, the push rod 13 is hinged on the cover body 12, and a support rod 14 is fixed on the mounting plate 16. The middle or upper part of the push rod 13 is hinged on the support rod 14. The push rod 13 is used to push the slider 10 to slide in the direction of the limit plate 11. A displacement sensor for detecting the sliding of the slider 10 is installed on the side wall of the hopper 6. Specifically, when the cover body 12 is covered on the hopper 6, the limit plate 11 is in a state of being in contact with the side wall of the hopper 6, and has a certain limiting effect on the end of the cover body 12. When the cover body 12 is covered, if the cover body 12 pushes the limit plate 11 to deflect, the slider 10 will also slide to a certain extent. The displacement sensor can be used to determine whether the hopper 6 is completely covered. When the cover body 12 slides with the contraction of the second telescopic rod 15, the hopper 6 is opened, and at the same time, the cover body 12 drives the push rod 13 to swing, and the push rod 13 pushes the slider 10 to slide, so that the limit plate 11 is deflected. After the limit plate 11 is deflected, it can be hooked at the opening of the melting furnace, and then the third telescopic rod 7 is extended and retracted to adjust the hopper 6 to deflect relative to the bottom plate 5, so that the molten aluminum in the hopper 6 can enter the melting furnace.

[0026] In another embodiment of the present invention, Figure 2 , Figure 3 As shown, in order to facilitate the discharge of molten aluminum from the hopper 6, an inclined guide surface 20 is provided on the side of the inner wall of the hopper 6 facing away from the first slide plate 3, and the lower end of the guide surface 20 is inclined toward the first slide plate 3. The setting of the guide surface 20 can have a certain guiding effect on the discharge of molten aluminum, but only when the guide surface 20 is deflected to a horizontal state or even the free end of the guide surface 20 is inclined downward, can the molten aluminum in the hopper 6 be completely discharged, which requires the hopper 6 to deflect at a larger angle, which will inevitably be affected by the operating space and the difficulty of operation. For this reason, in this embodiment, a liquid outlet pipe 19 is fixed in the hopper 6, and the liquid outlet pipe 19 includes a first section 21 fixed at the bottom of the hopper 6, a second section 22 fixed on the guide surface 20, and a third section 23 connected between the first section 21 and the second section 22. The inner diameters of the first section 21 and the second section 22 are both larger than the inner diameter of the third section 23. The third section 23 is provided with a liquid inlet hole 24, and the first section 21 extends through the hopper 6.

[0027] When the hopper 6 is in an inclined state and the guide surface 20 is not yet in a horizontal state, the remaining molten aluminum in the hopper 6 will remain in the triangular area formed by the guide surface 20 and the bottom of the hopper 6. At this time, high-pressure gas is introduced into the first section 21 of the liquid outlet pipe 19, and the high-pressure gas flows through the first section 21, the third section 23, and the second section 22 in sequence. When flowing through the third section 23, since the inner diameter of the third section 23 becomes smaller, according to the Bernoulli principle, the flow rate of the high-pressure gas is accelerated, generating negative pressure, and the molten aluminum is adsorbed into the liquid outlet pipe 19 through the liquid inlet hole 24, so that the molten aluminum is discharged from the second section 22 into the casting furnace.

[0028] The liquid inlet hole 24 is arranged at an angle, and one end of the liquid inlet hole 24 located in the third section 23 is inclined toward the guide surface 20. When the high-pressure gas flows through the third section 23, molten aluminum is attracted to enter. The inclined direction of the liquid inlet hole 24 is arranged so that the molten aluminum tends to flow in the same direction as the high-pressure gas after entering, which is more convenient to drive the flow of molten aluminum and reduce the possibility of high-pressure gas flowing out of the liquid inlet hole 24.
