Description

Technical Field

[0001] The utility model relates to the technical field of waste aluminum recovery and smelting, in particular to an aluminum scrap feeding device. Background Art

[0002] Aluminum is a recyclable metal. The recycling of scrap aluminum not only saves resources, but also reduces environmental pollution. With the advancement of my country's dual-carbon strategic goals, the efficient recycling of scrap aluminum has become an inevitable pursuit for the high-quality development of aluminum processing enterprises.

[0003] The recycling method of scrap aluminum in society is usually to crush large pieces of scrap aluminum into small-sized aluminum chips, and then send them into a smelting furnace for melting. During the melting process, a certain proportion of new aluminum ingots can be added to adjust the alloy composition to meet specific production needs. After that, new aluminum products are formed after refining, casting and reprocessing.

[0004] In the existing production technology, when recycling and remelting aluminum scraps, the aluminum scraps are usually packaged first, and the hopper is lifted by a forklift and aimed at the furnace door, and the packaged aluminum scraps are placed in the hopper by an overhead crane, and finally the slag arm of the forklift is used to push the aluminum scraps into the smelting furnace, such as the prior art "A shovel hopper for recycling and smelting of waste aluminum" (publication number: CN207987311U), but there are still the following technical problems:

[0005] In the prior art, an opening is arranged at the front end of the hopper, so that aluminum chips can fall into the smelting furnace from the opening; a sleeve is arranged at the rear end of the hopper, so that a forklift can be inserted into the sleeve to lift the hopper; and the bottom of the hopper is an inclined surface. When the fork of the forklift lifts the hopper, the fork rod has a contact point with the sleeve, and the fork tip has a contact point with the bottom of the hopper, and the rest of the fork does not contact the material opening, and the contact area is too small. Therefore, when the slag scraping arm of the forklift pushes the aluminum chips into the furnace door, the friction force of the aluminum chips on the hopper can easily cause the hopper as a whole to slide toward the furnace door, or even cause the hopper to slip off the fork rod of the forklift. In severe cases, the hopper may hit the smelting furnace or directly slide into the furnace from the furnace door, causing the smelting furnace to be damaged or the hopper to be scrapped. Utility Model Content

[0006] The utility model provides an aluminum chip feeding device, which can solve the problem that the feeding hopper in the prior art is easy to slip off the fork of a forklift and hit the smelting furnace or even slide into the furnace door when in use, causing the smelting furnace to be damaged or the feeding hopper to be scrapped.

[0007] The present application provides the following technical solution: an aluminum chip feeding device, comprising a hopper body and a socket assembly fixed below the hopper body, the hopper body comprising a bottom plate, and the socket assembly is located below the bottom plate;

[0008] The socket assembly includes a plurality of reinforcing plates fixed below the bottom plate, a socket fixed on the reinforcing plates, and a socket baffle fixed on the end of the socket;

[0009] The socket is a rectangular metal tube, and a plurality of reinforcing plates are symmetrically located on both sides of the socket and are equidistantly arranged along the length direction of the socket. The length of the socket is 0.4-0.7 times the length of the bottom plate.

[0010] The plug sleeve baffle is a frame structure, which is sleeved on the end of the plug sleeve and fixed.

[0011] Beneficial effects:

[0012] 1. The length of the sleeve is designed to be 0.4-0.7 times the length of the base plate, so that the fork of the forklift has sufficient insertion depth, and when the fork is inserted into the sleeve, it can have a larger contact area with the sleeve, which can not only improve the support stability of the bucket during the forklift handling process, but also when the forklift's slag arm pushes the aluminum chips into the furnace door, the bucket is not easy to slip off the fork of the forklift due to the friction of the aluminum chips, thereby effectively preventing the bucket from hitting the melting furnace or sliding into the furnace, avoiding damage to the melting furnace and causing safety accidents.

[0013] 2. The sleeve is made of rectangular steel pipe, which not only has good strength and stability, can withstand heavy loads without deformation, but also can adapt to the shape of the fork, so that when the forklift lifts the hopper body, it can improve the stability of the fork's support for the sleeve.

[0014] 3. The baffle at the end of the sleeve can prevent the fork from deviating during the insertion process, play a role in positioning and guiding, and ensure the accuracy and safety of forklift operation.

[0015] 4. Multiple reinforcement plates are symmetrically located on both sides of the sleeve and are arranged equidistantly along the length of the sleeve. This design increases the overall rigidity of the sleeve, improves the stability of the forklift fork during insertion, and enhances the bearing capacity of the sleeve.

[0016] Furthermore, the hopper body also includes a base frame assembly fixed below the bottom plate, a side plate frame fixed above the bottom plate, and side plates fixed on the side plate frames; the side plate frames are provided with two groups, which are symmetrically fixed on both sides of the width direction of the bottom plate, and the side plates are multiple in number and fixed on the outer sides of the two side plate frames.

[0017] Beneficial effects: The bottom plate is the main load-bearing part of the hopper, used to place and carry aluminum chips. The bottom frame assembly is fixed under the bottom plate to provide support and structural stability for the hopper and enhance the overall rigidity of the hopper. The side plate frame is used to fix the side plate and enhance the lateral stability of the hopper. The side plate is used to enclose the side of the hopper to ensure that the aluminum chips are completely added to the furnace and prevent the aluminum chips from scattering out of the furnace from the side of the hopper.

[0018] Furthermore, the side plate frame includes a plurality of first vertical frames symmetrically fixed on both sides of the bottom plate in the width direction, a second vertical frame fixed on the four corners of the bottom plate, and a transverse frame fixed above the first vertical frame and the second vertical frame.

[0019] Beneficial effect: Through the combination of the first vertical frame, the second vertical frame and the transverse frame, vertical and transverse supports are increased, and the overall structural stability of the hopper is improved, which can not only prevent aluminum chips from overflowing from the side, but also provide additional lateral support during transportation to reduce shaking.

[0020] Furthermore, the base frame assembly includes a plurality of first base frames, second base frames and third base frames fixed below the bottom plate, and the second base frames are arranged perpendicularly to the first base frames and the third base frames respectively.

[0021] Beneficial effect: Through the combination of the first base frame, the second base frame and the third base frame, the bearing capacity of the bottom plate is strengthened, the rigidity of the hopper is improved, and it is ensured that the hopper can bear heavier aluminum chips.

[0022] Furthermore, the first base frame is provided with multiple ones, which are evenly distributed along the width direction of the bottom plate, the second base frame is provided with multiple ones, which are respectively located at the two ends of the first base frame and arranged perpendicular to the first base frame, and the third base frame is provided with multiple ones, which are evenly distributed along the width direction of the bottom plate and are in the same straight line with the first base frame, and are located at one end under the bottom plate away from the socket.

[0023] Beneficial effect: The base frames are arranged perpendicular to each other to form a cross support for the bottom plate. Together with the third base frame, a stable frame support structure is formed, which enables the hopper to withstand a large weight, improves the overall structural stability and carrying capacity, prevents the hopper from deformation, and extends the service life of the hopper.

[0024] Furthermore, it also includes a support assembly fixed below the bottom plate, and the support assembly includes leg guards evenly distributed at four points below the bottom plate and a reinforcing rib assembly fixed between the leg guards.

[0025] Beneficial effect: Four guard legs are evenly distributed at four points under the bottom plate to provide bottom support for the hopper. During the placement of aluminum chips, the stability of the hopper can be ensured. The reinforcing rib assembly is used to enhance the connection strength between the guard legs and improve the overall structural stability of the hopper.

[0026] Furthermore, the reinforcing rib assembly includes a first reinforcing rib and a second reinforcing rib both fixed between the leg guard and the bottom plate, a third reinforcing rib fixed between two leg guards on the same side, and a fourth reinforcing rib fixed between the leg guards on the opposite sides.

[0027] Beneficial effect: The first reinforcing rib and the second reinforcing rib are used to increase the connection strength between the leg guard and the bottom plate to prevent the bottom plate from sinking and deforming downward when bearing the weight of aluminum chips. The third reinforcing rib and the fourth reinforcing rib are used to increase the connection strength between the leg guards to prevent the leg guards from tilting and deforming due to excessive load, thereby improving the overall strength of the hopper.

[0028] Furthermore, a foot pad is fixed to the bottom of the leg guard.

[0029] Beneficial effect: The foot pad can increase the contact area between the leg guard and the ground, which can not only reduce the pressure on the leg guard, prevent the leg guard from deformation and damage, and extend the service life of the leg guard, but also has an anti-slip function, which improves the stability and safety of the hopper during placement and transportation.
