Description

Technical Field

[0001] The utility model belongs to the technical field of scrap steel processing, in particular to a crushing and rust removal mechanism for scrap steel processing. Background Art

[0002] Scrap steel refers to the steel waste that does not become products in the production process of steel mills, as well as the steel materials in equipment and components that are scrapped after use. Scrap steel is made of steel, and scrap steel is made of pig iron. They are collectively called scrap steel. Before the rusty scrap steel is reused, it needs to be derusted and crushed to facilitate its subsequent processing and reuse.

[0003] Among them, after searching, it was found that the scrap steel crusher with application number CN202022101754.X includes a frame, a first crushing mechanism, a second crushing mechanism, a first tool holder and a second tool holder. The first crushing mechanism includes a first crushing roller, a first planetary reducer and a first hydraulic motor, and the first tool holder is driven to rotate by the first crushing roller. The second crushing mechanism includes a second crushing roller, a second planetary reducer and a second hydraulic motor, and the second tool holder is driven to rotate by the second crushing roller. This new type has the functions of shearing, tearing, pulling and biting the scrap steel, so that the scrap steel can be crushed, so the dust is small and the noise is low; among them, the shortcomings are as follows:

[0004] After research and analysis, it was found that the device uses two crushing rollers that rotate in opposite directions to crush the scrap steel. During the crushing process, the two crushing rollers need to be driven by two drive motors, which results in greater consumption of electrical energy, which is not environmentally friendly. In addition, the thickness and shape of the scrap steel are different, and it is difficult to meet some crushing requirements by only a single crushing with two crushing rollers. Therefore, the crushing efficiency of the device needs to be improved. In addition, general scrap steel has rust on the surface. In order to facilitate the reuse of the scrap steel after crushing, the rust needs to be removed. The device does not have a rust removal function, so it is necessary to carry out the crushing and rust removal work separately. The steps are relatively cumbersome and the functions are relatively simple. Utility Model Content

[0024] Reference Figure 1-3 In this embodiment, the adjustment mechanism includes a movable groove seat 7, a groove 701, a movable seat 8, a connecting frame 801, and a rubber block 802.

[0025] Reference Figure 1-3 In this embodiment, a movable groove seat 7 is provided on the outer side of the water outlet of the jet seat 603, and a groove 701 is provided on the inner wall of the movable groove seat 7, and the number of the grooves 701 is several and arranged in a ring array.

The movable seat 8 is connected to the nozzle 604 through the connecting frame 801. Before starting, the movable seat 8 can be rotated in the movable groove seat 7 to make the movable groove seat 7 and the corresponding groove 701 have a damping fit, so that the angle of the nozzle 604 can be adjusted and fixed under the action of the hose.

[0026] Reference Figure 1 In this embodiment, the drive motor connected to the crushing roller A102, the hydraulic pump matched with the hydraulic telescopic rod 5, the drive motor matched with the drum screen, the motor 9, and the drive motor of the multi-section conveyor belt 1001 are all electrically connected to the external power supply through a switch.

[0027] Working principle: First, the staff uses the telescopic hose to pass the guide port of the guide trough 104 into the feed port of the drum screen 501, and then the staff adds the scrap steel through the feed port 101, and at the same time starts the driving motor of the crushing roller A102 to drive the crushing roller A102 on one side to rotate clockwise, and drives the crushing roller B103 on one side to rotate synchronously under the transmission of the chain. At the same time, the crushing roller A102 and crushing roller B103 on the other side are driven to rotate counterclockwise under the transmission of the bevel gears A2 and B301. The diameter of gear A2 is twice as large as that of gear A2, so the rotation speed of crushing roller B103 is faster. Under the operation of two groups of crushing rollers with different rotation speeds, the scrap steel is crushed multiple times. The crushed scrap steel blocks are guided through the guide trough 104 and the guide plate A105, so that the crushed scrap steel blocks enter the drum screen 501. Then the staff disconnects the connection of the feed inlet. At this time, the hydraulic telescopic rod 5 is controlled to retract. With the cooperation of the rotating shaft, the tail of the drum screen 501 is tilted downward, so that the scrap steel blocks inside it slide to the tail of the drum screen 501. At this time, the rust remover is pumped into the drum screen 501 through the water pump of the external water tank. The scrap steel blocks are transported to each nozzle 604 by the pipe and sprayed evenly. The scrap steel blocks transported by vibration are constantly moved and turned over, and are evenly contacted with the sprayed rust remover to achieve the rust removal effect. Then, the motor 9 can be started to drive the pulley 901 to rotate, and the movable seats 8 are driven to rotate under the action of the rotating joint 601 under the transmission of the belt, so as to further expand the spraying area of ​​the rust remover by using the centrifugal force, thereby effectively improving the spraying efficiency. The sprayed rust remover is diverted through the water guide groove at the bottom of the drum screen 501 bracket and collected through the water receiving groove. Then, the staff controls the extension of the hydraulic telescopic rod 5 to make the drum screen The head of 501 is tilted downward, so that the steel blocks after preliminary rust removal fall out through the discharge port of the head of the drum screen 501 and fall into the conveyor belt surface of the multi-section conveyor belt 1001 in the water reservoir 10. At this time, the steel blocks are transported by starting the multi-section conveyor belt 1001. During the transportation, the rust remover loaded in the water reservoir 10 is used to remove rust on the steel blocks again. In addition, before starting, the movable seat 8 can be rotated in the movable groove seat 7 to make the movable groove seat 7 and the corresponding groove 701 damping fit, so that the angle of the nozzle 604 can be adjusted and fixed under the action of the hose.
