The processing of deoxidized aluminum rods is a complex and delicate process. Among them, the crushing process as the primary process of deoxidized aluminum rod processing is related to the efficiency and quality of the entire production system.

[0017] A production process of a deoxidized aluminum rod production system based on scraps as described above comprises the following steps:

[0018] S1. Crushing: Use crushing equipment to crush large-volume aluminum scrap into small-volume scrap, and then use crushing equipment to crush the small-volume scrap into small pieces with a particle size of 1-5mm;

[0019] S2. Batching: Weigh the crushed raw materials through a floor scale, add various raw materials into the batching unit and mix them by stirring, and place the prepared raw materials in a movable hopper;

[0020] S3, briquetting: add the prepared raw materials into the briquetting unit, use the hydraulic chip cake machine to briquette, and press into aluminum cakes with a diameter of 120 mm and a thickness of 80 mm;

[0021] S4, preheating: send the aluminum cake into the preheating unit and heat it in a heating furnace for 2.5-3 hours to 500°C;

[0022] S5, extrusion: the heated aluminum cake is fed into the extrusion unit, and the aluminum cake is formed into a rod shape by an aluminum extruder;

[0023] S6, rewinding: using the rewinding unit, the extruded aluminum rod is rewound into a coil by a synchronous rewinding machine and cooled to room temperature.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. When the aluminum scraps enter the guide hopper, the reciprocating extension and retraction of the electric push rod is used to make the blanking frame reciprocate, and the aluminum scraps are evenly discharged axially to the middle and both sides of the crushing roller, so that the crushing teeth at different positions are all involved in the crushing, avoiding uneven wear of the crushing teeth.

[0026] 2. When the aluminum material passes through the blanking frame and is blocked, the present invention uses an electric telescopic rod to drive the wedge block to move upward, and under the action of the elastic telescopic rod, the guide plates on both sides are driven away from each other, thereby increasing the opening size of the blanking frame to discharge the blocked material and eliminate the blockage. When the volume of the aluminum scrap is relatively small, the electric telescopic rod is used to move the wedge block downward, and the guide plates on both sides are closed to reduce the opening of the blanking frame and prevent the aluminum scrap from spreading.

[0027] 3. When the material passes through the blanking frame, the present invention uses the electric telescopic rods on both sides to make the frame plates on both sides move back and forth in opposite directions. When the frame plates on both sides move in opposite directions, the aluminum material is squeezed into a flat shape. At the same time, the movable seat and the first hydraulic rod are locked and fixed. The first hydraulic rods on both sides are used to synchronously extend and retract to drive the movable seats on both sides to move back and forth in opposite directions. When the movable seats on both sides move in opposite directions, the tooth blocks are interlaced and meshed with each other to make the flat aluminum material become concave and convex, so that the crushing teeth can quickly bite the aluminum scraps to prevent the aluminum scraps from slipping on the crushing teeth.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] First embodiment

[0036] See also Figure 1-5 The present embodiment provides a technical solution: a deoxidized aluminum rod production system based on scraps, including a crushing unit, a batching unit, a briquetting unit, a preheating unit, an extrusion unit and a rewinding unit. The crushing unit is used to crush the aluminum scraps, and the crushed aluminum material enters the batching unit to be mixed and stirred with other materials for batching. After the batching is completed, the aluminum material is sent to the briquetting unit to be pressed into an aluminum cake, and the aluminum cake is sent to the preheating unit for heating. Finally, the heated aluminum cake is placed in the extrusion unit, and the aluminum cake is extruded into a rod shape to realize the forming of the deoxidized aluminum rod.

[0037] The crushing unit includes crushing equipment and pulverizing equipment. The crushing equipment includes a mounting frame 1. A feed hopper 101 is provided on the top of the mounting frame 1. A guide hopper 102 is provided on the inner side of the feed hopper 101. A crushing assembly 2 is provided on the top of the mounting frame 1. The crushing assembly 2 is located below the guide hopper 102. An adjustment assembly 4 is provided at the bottom of the guide hopper 102. An auxiliary assembly 5 is provided in the crushing assembly 2. The adjustment assembly 4 is used to adjust the opening size of the blanking frame 301 according to the volume of the incoming aluminum material. The auxiliary assembly 5 is used to clean the aluminum material stuck between the crushing teeth.

[0038] The crushing assembly 2 includes a crushing box 201 and two crushing rollers 203 that cooperate with each other. The crushing box 201 is arranged on the top of the mounting frame 1. The two sides of the crushing box 201 are symmetrically rotatably connected with the mounting shafts 202. The two crushing rollers 203 are respectively fixedly sleeved on the mounting shafts 202 on both sides. The crushing rollers 203 on both sides are provided with crushing teeth that mesh with each other. The crushing teeth adopt the crushing teeth of the double-axis metal shredder in the prior art. A discharge hopper 207 is provided at the bottom of the crushing box 201. The discharge hopper 207 is used to discharge the crushed aluminum material.

[0039] The outer ends of the installation shafts 202 on both sides are sleeved with mutually meshing gears 204, and the side of the mounting frame 1 is provided with a driving motor 205 and a reducer 206. The output shaft of the driving motor 205 is fixedly connected to the input shaft of the reducer 206, and the output shaft of the reducer 206 is fixedly connected to the end of one of the installation shafts 202.

[0040] Specifically, the rotation of the driving motor 205 drives one of the mounting shafts 202 to rotate through the reducer 206, and the meshing of the two gears 204 realizes the opposite rotation of the mounting shafts 202 on both sides, so that the crushing teeth on both sides mesh with each other to crush the aluminum scraps.

[0041] When in use, first start the drive motor 205, drive the installation shaft 202 on one side to rotate through the reducer 206, and use the meshing of the gears 204 on both sides to achieve the mutual engagement of the crushing rollers 203 on both sides, and transport the aluminum scraps to the guide hopper 102 through the conveyor belt, and fall into the engagement position between the crushing rollers 203 on both sides through the blanking frame 301, and use the mutually engaged crushing teeth to achieve the crushing of the aluminum scraps. The crushed aluminum material is sent to the crushing equipment through the discharge hopper 207 through the conveyor belt for further crushing. The crushed small volume aluminum material is weighed by a floor scale, and other raw materials are added in proportion to mix and stir to complete the batching. Then, the prepared aluminum material is pressed into a cake shape by a hydraulic chip cake machine and placed in a heating furnace for preheating, and finally placed in an extrusion unit, and the aluminum material is formed into a rod shape by an aluminum extruder.

[0042] However, during the crushing process, since the blanking frame 301 is always located at the center of the crushing rollers 203 on both sides, the aluminum material always falls in the middle of the crushing roller 203. After long-term use, the crushing teeth at both ends and the middle of the crushing roller 203 will be unevenly worn, shortening the service life of the crushing roller 203. In order to solve the above problem:

[0043] A material leveling component 3 is provided at the bottom of the guide hopper 102, and the material leveling component 3 is used for the uniform entry of aluminum materials. The material leveling component 3 includes a blanking frame 301, and the blanking frame 301 is provided at the bottom end of the guide hopper 102. The center of the blanking frame 301 coincides with the horizontal center axis between the two crushing rollers 203, and an elastic frame is provided between the top of the blanking frame 301 and the bottom of the guide hopper 102. The elastic frame is made of rubber, and guide plates 302 are symmetrically provided on both sides of the blanking frame 301. A frame rod 303 is provided between the inner walls on both sides of the feed hopper 101, and a guide groove 304 slidably connected to the guide plate 302 is opened in the middle of the frame rod 303, and the guide groove 304 is used to realize the support and limitation of the guide plate 302. An electric push rod 305 is provided on the side of the blanking frame 301, and the fixed end of the electric push rod 305 is fixedly connected to the side of the feed hopper 101.

[0044] Specifically, the horizontal extension and retraction of the electric push rod 305 drives the blanking frame 301 to reciprocate axially along the installation shaft 202, and the elastic frame is stretched to achieve reciprocating movement of the position of the blanking frame 301, thereby achieving uniform feeding of materials.

[0045] When in use, when the aluminum scraps enter the guide hopper 102, the electric push rod 305 is started, and the reciprocating extension and retraction of the electric push rod 305 drives the blanking frame 301 to reciprocate along the direction of the installation shaft 202. At the same time, the guide plate 302 reciprocates in the guide groove 304, and the elastic frame is repeatedly stretched with the reciprocating motion of the blanking frame 301. During the reciprocating motion of the blanking frame 301, the aluminum scraps fall evenly along the biting positions of the crushing rollers 203 on both sides, so that the crushing teeth on each crushing roller 203 are involved in the crushing of the aluminum scraps, ensuring that each crushing tooth is evenly worn and the service life is extended.

[0046] In addition, when a large volume of aluminum scrap passes through the blanking frame 301, it is easy to get stuck inside the blanking frame 301, resulting in material blocking, which affects the normal falling of the material. Therefore, the following improvements are made:

[0047] The blanking frame 301 is surrounded by four frame plates, wherein the two frame plates connected to the guide plates 302 on both sides are slidably connected to the inner sides of the other two frame plates, and the top of the frame plate connected to the guide plates 302 is slidably matched with the bottom of the elastic frame, providing conditions for the frame plates on both sides to close or separate with each other.

[0048] The adjustment component 4 includes two symmetrically arranged wedge blocks 403, the inclined surfaces of the wedge blocks 403 on both sides are respectively fitted with the ends of the guide plates 302 on both sides, and an electric telescopic rod 404 is provided on the top of the wedge block 403, and the fixed end of the electric telescopic rod 404 is fixedly connected to the side of the guide hopper 102.

[0049] Furthermore, a connecting seat 401 is provided on the top of the guide plate 302, and an elastic telescopic rod 402 is provided between the connecting seat 401 and the side of the guide hopper 102. The elastic telescopic rod 402 adopts two rod-shaped structures that are connected to each other, and the telescopic reset of the rod body is achieved by compression and release of the spring member arranged inside.

[0050] Specifically, in the initial state, the opening size of the blanking frame 301 is between the maximum and minimum states, the elastic telescopic rod 402 is in a compressed state, and the synchronous extension of the electric telescopic rods 404 on both sides drives the wedge block 403 to move downward, and the wedge block 403 cooperates with the end of the guide plate 302 to make the frame plates on both sides close to each other, and the elastic telescopic rod 402 is compressed, so that the opening of the blanking frame 301 is reduced. When the electric telescopic rods 404 on both sides drive the wedge block 403 to retract upward, the elastic telescopic rod 402 extends and resets, so that the opening of the blanking frame 301 increases.

[0051] It should be noted that when the electric push rod 305 contracts and drives the blanking frame 301 to move horizontally, after the blanking frame 301 moves to the farthest distance, the inclined surfaces of the guide plate 302 and the wedge block 403 still maintain contact.

[0052] During use, a material level sensor is arranged on the inner side of the guide hopper 102 to monitor the height of the material in the guide hopper 102. When the aluminum material passes through the blanking frame 301, the material level sensor detects that the material level is greater than the set threshold value, then it is determined that material blockage has occurred in the guide hopper 102. At this time, the electric telescopic rod 404 is started while the blanking frame 301 reciprocates, and the wedge block 403 is driven to move upward by the synchronous contraction of the electric telescopic rods 404 on both sides. At this time, the compressed elastic telescopic rod 402 is extended and drives the guide plates 302 on both sides to move backwards, so that the frame plates on both sides of the blanking frame 301 move away from each other to increase the opening of the blanking frame 301, so that the blocked material can be discharged smoothly, thereby eliminating the blockage.

[0053] It is worth noting that when the volume of the aluminum scraps to be crushed is small, if the opening of the blanking frame 301 is still in a large state, some of the aluminum materials will be scattered around during the falling process. At this time, it is necessary to reduce the opening of the blanking frame 301, that is, to use the synchronous extension of the electric telescopic rods 404 on both sides to move the wedge block 403 downward, so that the guide plates 302 on both sides are closed together, and the opening of the blanking frame 301 can be reduced to prevent the aluminum scraps from spreading in the direction away from the biting position of the crushing roller 203.

[0054] In addition, during the crushing process of aluminum scraps, some debris will get stuck in the gaps between the crushing teeth, affecting the crushing effect of the material. In order to solve this problem:

[0055] The auxiliary component 5 includes two symmetrically arranged movable seats 501, the side surfaces of the movable seats 501 are slidably matched with the inner wall of the crushing box 201, and toothed blocks 502 are evenly spaced on the opposite sides of the movable seats 501 on both sides. The toothed blocks 502 on the movable seats 501 on both sides are staggered, so that when the movable seats 501 on both sides move towards each other, the toothed blocks 502 on both sides bite each other, and the toothed blocks 502 on the same side and the crushing teeth on the crushing roller 203 are staggered, so that when the toothed blocks 502 move downward, they fit with the gap between the two adjacent crushing teeth on the same side.

[0056] Furthermore, a second hydraulic rod 504 is provided at the bottom of the movable seat 501 through a second locking mechanism, and the fixed end of the second hydraulic rod 504 is provided on the inner support of the crushing box 201. The second locking mechanism disengages the movable seat 501 from the telescopic end of the second hydraulic rod 504 when unlocking.

[0057] Specifically, when material is stuck between the two crushing teeth, the second hydraulic rod 504 contracts to drive the movable seat 501 to move downward, so that the tooth block 502 corresponds to the gap between the two crushing teeth, and the end of the tooth block 502 fits with the circumferential surface of the crushing roller 203, so as to clear the aluminum material between the two crushing teeth.

[0058] During use, in order to prevent material from getting stuck between the crushing teeth, the gap between the two crushing teeth needs to be cleaned regularly. During cleaning, the second hydraulic rod 504 is started to contract and drive the movable seat 501 to move downward, so that the tooth block 502 on the same movable seat 501 cooperates with the gap between two adjacent crushing teeth on the same crushing roller 203, so that when the crushing roller 203 drives the crushing teeth to rotate, the tooth block 502 is used to clear the material stuck in the gap between the crushing teeth.

[0059] In addition, when the block-shaped and lump-shaped aluminum scraps fall between the crushing rollers 203 on both sides, the block-shaped and lump-shaped aluminum scraps are easily rolled along with the rotation of the crushing rollers 203 on both sides, which affects the normal engagement of the crushing teeth on both sides with the block-shaped and lump-shaped aluminum scraps, thereby affecting the crushing of the block-shaped and lump-shaped aluminum scraps and the crushing of subsequent materials. Therefore, the following improvements are made:

[0060] The side of the movable seat 501 is provided with a first hydraulic rod 503 through a first locking mechanism. The fixed end of the first hydraulic rod 503 passes through and is fixed to the side of the mounting frame 1. After the second hydraulic rod 504 lifts the movable seat 501 to a position corresponding to the telescopic end of the first hydraulic rod 503, the first locking mechanism is locked and fixed to the side of the movable seat 501. Then, the second locking mechanism releases the lock with the movable seat 501 and disengages from the second hydraulic rod 504. The first locking mechanism and the second locking mechanism are preferably electromagnetic locking devices.

[0061] When in use, when the material passes through the blanking frame 301, the wedge block 403 is driven to move up and down by the rapid extension of the electric telescopic rods 404 on both sides, and the guide plates 302 on both sides respectively drive the frame plates on both sides to close and move away synchronously under the action of the elastic telescopic rods 402. In the process of closing the frame plates on both sides, the passing aluminum material is squeezed so that the block or ball-shaped aluminum scraps are squeezed into a flat shape. At the same time, the second hydraulic rod 504 is used to drive the movable seat 501 to move upward to the position corresponding to the first hydraulic rod 503, and the first locking mechanism is used to lock the telescopic end of the first hydraulic rod 503 with the side of the movable seat 501. The second locking mechanism at the telescopic end of the hydraulic rod 504 releases the lock on the bottom of the movable seat 501, and the rapid telescopic movement of the first hydraulic rods 503 on both sides respectively drives the movable seats 501 on both sides to move towards and away from each other. When the movable seats 501 on both sides move towards each other, the toothed blocks 502 on both sides of the movable seats 501 are staggered and meshed with each other, so that the aluminum material is squeezed into a flat shape by the frame plates on both sides and then squeezed by the toothed blocks 502 on both sides, so that the aluminum scraps are flat and concave-convex, so that the crushing teeth on both sides can bite the aluminum scraps, so that the aluminum scraps can be quickly crushed and prevented from slipping on the crushing roller 203.

[0062] It should be noted that when it is time to clean the gap between the crushing teeth, the second locking mechanism at the telescopic end of the second hydraulic rod 504 is re-locked with the bottom of the movable seat 501, and then the first locking mechanism is released from the lock on the side of the movable seat 501. The second hydraulic rod 504 is contracted to move the movable seat 501 downward until the tooth block 502 cooperates with the gap between the crushing teeth, and then the cleaning operation can be carried out.
