Description

Technical Field

[0001] The utility model relates to the technical field of scrap steel recycling, in particular to a scrap steel briquetting machine. Background Art

[0002] Steel can be obtained by smelting ore or by recycling scrap steel. In order to facilitate storage and transportation, it is necessary to briquette the scrap steel.

[0003] The prior art discloses a scrap steel briquetting mechanism (application number: CN202110338183.8). The main body of the briquetting groove is of a square structure. A hydraulic press is arranged directly above the briquetting groove. A briquetting block with the same shape and size as the briquetting groove is arranged on the compression hydraulic rod below the hydraulic press. A waste steel transmission mechanism is arranged on one side. A lifting device for lifting and pushing out the pressed scrap steel block is arranged at the bottom of the briquetting groove. This device can safely and quickly transport the scrap steel to the compressor.

[0004] In the prior art, the steel is mainly extruded by two reversely sliding briquetting blocks, and cooperates with the briquetting groove to form an ingot. When the steel falls into the briquetting groove and is extruded, due to gravity, it will accumulate at the bottom of the briquetting groove. The top of the briquetting block at the bottom is flat. After the steel is extruded, it will deform and extend towards the inner wall of the briquetting groove. This makes the bottom of the briquetting groove receive too much thrust, and the lower port of the briquetting groove is a relatively weak area, which is easy to deform or tear. The flat briquetting block is not convenient for discharging materials after briquetting.

[0005] Therefore, we propose a scrap steel briquetting machine. Content of the Utility Model

[0006] The utility model mainly solves the technical problem that the flat briquetting block is not convenient for discharging materials, and provides a scrap steel briquetting machine.

A plurality of paddle blades are fixedly installed on the wall surface of the rotating shaft. The rotating shaft extends into the interior of the storage cylinder, and the drum can push the rotating shaft and the paddle blades to stir the liquid stored in the cavity of the storage cylinder.

[0012] As a preferred embodiment of the present utility model, both the drum and the storage cylinder are cylindrical structures with one end open. The storage cylinder is installed inside the drum. The outer diameter of the storage cylinder is smaller than the inner diameter of the drum. A bearing is installed in the cavity of the drum, and the storage cylinder is inserted into the inner ring of the bearing.

[0013] As a preferred embodiment of the present utility model, the discharging assembly further includes an end cap. The end cap is threadedly connected to the storage cylinder and seals the port of the storage cylinder. An axial hole is opened at the end of the end cap. A bushing is fixedly provided in the axial hole, and a sealing ring is provided inside the bushing. The rotating shaft passes through the sealing ring and extends into the cavity of the storage cylinder.

[0014] As a preferred embodiment of the present utility model, the paddle blades form a rectangular plate structure. The paddle blades do not contact the inner wall of the storage cylinder.

[0018] Beneficial effects

[0019] The present utility model provides a scrap steel briquetting machine, which has the following beneficial effects:

[0020] 1. The scrap steel briquetting machine, by setting a first extrusion plate and a second extrusion plate, uses two push cylinders to push the first extrusion plate and the second extrusion plate closer to each other respectively, thereby extruding the steel materials falling into the forming cylinder into ingots. The compression effect is better and the efficiency is higher. At the same time, the rising second extrusion plate can promote discharging, facilitating the discharge of the steel ingots from the forming cylinder. By opening forming grooves, the specific shapes of the second extrusion plate and the forming grooves are referred to the figure. During the extrusion forming stage, the steel materials are located in the forming grooves. Through the limitation of the steel materials by the forming grooves, the steel materials at the bottom layer fit the inner wall of the second extrusion plate, thereby reducing the extrusion force on the bottom port of the forming cylinder and lowering the probability of deformation and tearing of the opening position of the forming cylinder easily squeezed by the steel materials. During the discharging stage, the forming grooves can promote the sliding of the steel ingots from the top of the second extrusion plate, facilitating discharging.

[0021] 2. The scrap steel briquetting machine realizes the guidance of the steel ingots through the steel ingots falling into the chute of the discharging chute and sliding, facilitating the transfer of the steel ingots by the transportation equipment. When the steel ingots slide from the top of the discharging chute, the steel ingots will push the roller to drive the rotating shaft and the paddle to rotate. By agitating the liquid pre-stored in the storage cylinder with the paddle, taking non-Newtonian liquid as an example, the rotation speed of the rotating shaft is restricted. The outer surface of the roller is provided with anti-slip lines to ensure the pushing effect of the steel ingots on the roller. By installing multiple rollers at the top of the discharging chute to form a deceleration channel, it can ensure the slow sliding of the steel ingots, reduce the huge impact formed when stopping due to excessive acceleration during the sliding process, and ensure the safety of discharging.

[0022] 3. The scrap steel briquetting machine, by setting an end cover, uses the end cover to block the port of the storage cylinder, facilitating the storage of liquid and forming a seal. By setting a first insertion block and using a first slot to limit the first insertion block, the storage cylinder is kept stationary. While the second insertion block falls into the second limiting slot, it can not only ensure the support for the roller but also enable the roller to keep rotating, thereby facilitating the relative rotation of the roller with respect to the storage cylinder to agitate the liquid, ensuring the stability of decelerating the steel ingots. The installation is convenient and it is easy to disassemble and assemble for later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation

[0029] A scrap steel briquetting machine, as Figure 1 shown, includes:

[0030] Support frame 10, a frame structure for support;

[0031] As Figure 2 , Figure 3 and Figure 4 shown, forming cylinder 11, fixedly arranged on the top of support frame 10 for loading steel. Inside the forming cylinder 11, there are a first extrusion plate 12 and a second extrusion plate 13. At the top and bottom of the support frame 10, there is a push cylinder respectively for pushing the first extrusion plate 12 and the second extrusion plate 13 to approach each other and extrude the steel. The first extrusion plate 12 and the second extrusion plate 13 are respectively fixedly connected to the output shafts of the two push cylinders. A forming groove 14 is opened at the top of the second extrusion plate 13. The forming groove 14 can limit the steel against the inner wall of the forming cylinder 11. The forming groove 14 is opened on the side wall of the second extrusion plate 13 close to the discharge assembly. The depth of the forming groove 14 decreases uniformly towards the other side of the second extrusion plate 13. The second extrusion plate 13 forms an open rectangular frame with one side open and having a slope through the forming groove 14;

[0032] In this solution, by setting the first extrusion plate 12 and the second extrusion plate 13, the two push cylinders are respectively used to push the first extrusion plate 12 and the second extrusion plate 13 to approach each other, thereby extruding the steel falling into the forming cylinder 11 into ingots. The compression effect is better and the efficiency is higher. At the same time, the rising second extrusion plate 13 can promote discharge, facilitating the discharge of the steel ingot from the forming cylinder 11. By opening the forming groove 14, the specific shapes of the second extrusion plate 13 and the forming groove 14 refer to Figure 4 , during the extrusion forming stage, the steel is located in the forming groove 14. Through the limitation of the steel by the forming groove 14, the steel at the bottom layer fits the inner wall of the second extrusion plate 13, thereby reducing the extrusion force on the bottom port of the forming cylinder 11 and reducing the probability of deformation and tearing of the opening position of the forming cylinder 11 easily caused by the extrusion of the steel. During the discharge stage, the forming groove 14 can promote the sliding of the steel ingot from the top of the second extrusion plate 13, facilitating discharge.

[0033] As Figure 1 and Figure 5As shown in the figure, the discharging assembly is arranged on one side of the support frame 10 and is used to guide the steel after the pressing block. The discharging assembly includes a discharging groove 20, a roller 21, a rotating shaft 22, a paddle 23 and a storage cylinder 24. The discharging groove 20 is fixedly installed on one side of the support frame 10. The roller 21 is detachably connected to the discharging groove 20. The rotating shaft 22 is fixedly connected to the roller 21. A number of paddles 23 are fixedly installed on the wall surface of the rotating shaft 22. The rotating shaft 22 extends into the interior of the storage cylinder 24. The roller 21 can push the rotating shaft 22 and the paddle 23 to stir the liquid stored in the cavity of the storage cylinder 24. Both the roller 21 and the storage cylinder 24 are cylindrical structures with one end open. The storage cylinder 24 is installed inside the roller 21. The outer diameter of the storage cylinder 24 is smaller than the inner diameter of the roller 21. A bearing is installed in the cavity of the roller 21. The storage cylinder 24 is inserted into the inner ring of the bearing. The paddle 23 forms a rectangular plate structure and does not contact the inner wall of the storage cylinder 24. At least two paddles 23 are symmetrically arranged on the wall surface of the rotating shaft 22. The end of the rotating shaft 22 is fixedly connected to the inner end surface of the roller 21. By setting the discharging groove 20, the discharging groove 20 is inclined. The ingot falls into the groove of the discharging groove 20 and slides down, realizing the guidance of the ingot and facilitating the transfer of the ingot by the transportation equipment. When the ingot slides down from the top of the discharging groove 20, the ingot will push the roller 21 to drive the rotating shaft 22 and the paddle 23 to rotate. The liquid stored in the storage cylinder 24 in advance is stirred by the paddle 23. Taking non-Newtonian liquid as an example, the rotation speed of the rotating shaft 22 is limited. The outer surface of the roller 21 is provided with anti-slip lines to ensure the pushing effect of the ingot on the roller 21. By installing a plurality of rollers 21 at the top of the discharging groove 20 to form a deceleration channel, it can ensure that the ingot slides slowly, reduce the huge impact formed when accelerating too fast during the sliding process and stopping, and ensure the safety of discharging.

[0034] As Figure 5 shown in the figure, the discharging assembly further includes an end cover 25. The end cover 25 is threadedly connected to the storage cylinder 24 and seals the port of the storage cylinder 24. An axial hole is opened at the end of the end cover 25. A bushing is fixedly arranged in the axial hole. A sealing ring is arranged inside the bushing. The bushing and the sealing ring can ensure the still effective support for the rotating shaft 22. The rotating shaft 22 passes through the sealing ring and extends into the cavity of the storage cylinder 24. By setting the end cover 25, the port of the storage cylinder 24 is blocked by the end cover 25, which is convenient for storing liquid and forming a seal, and thus is convenient for later maintenance and disassembly.

[0035] As Figure 5As shown in the figure, the discharging assembly further includes a first inserting block 26 and a second inserting block 27. The first inserting block 26 is fixedly connected to the end of the storage cylinder 24, and the second inserting block 27 is fixedly connected to the outer end face of the roller 21. A first inserting slot and a second inserting slot are opened at the top of the discharging groove 20. The first inserting slot is rectangular, and the first inserting block 26 is a rectangular block adapted to the first inserting slot. The first inserting block 26 is inserted into the first inserting slot. The second inserting slot is a rectangular groove, and the bottom of the second inserting slot is semi-circular. The second inserting block 27 is a cylindrical structure. The second inserting block 27 is inserted into the second inserting slot and rotates in the second inserting slot. By setting the first inserting block 26 and using the first inserting slot to limit the first inserting block 26, the storage cylinder 24 is kept stationary, while the second inserting block 27 falls into the second limiting groove, which can not only ensure the support for the roller 21, but also enable the roller 21 to keep rotating. Furthermore, it is convenient for the roller 21 to rotate relative to the storage cylinder 24 to stir the liquid, ensuring the stability of the deceleration of the ingot, with convenient installation and easy disassembly and assembly for later maintenance.

[0036] The working principle of the present utility model: The first pressing plate 12 and the second pressing plate 13 are respectively pushed by two push cylinders to approach each other, thereby extruding the steel material falling into the forming cylinder 11 into an ingot. The compression effect is better and the efficiency is higher. At the same time, the rising second pressing plate 13 can promote discharging, facilitating the discharge of the ingot from the forming cylinder 11. By opening the forming groove 14, the specific shapes of the second pressing plate 13 and the forming groove 14 refer to Figure 4 , in the extrusion forming stage, the steel material is located in the forming groove 14. Through the limitation of the steel material by the forming groove 14, the bottommost steel material fits the inner wall of the second pressing plate 13, thereby reducing the extrusion force on the bottom port of the forming cylinder 11 and reducing the probability of deformation and tearing of the opening position of the forming cylinder 11 easily caused by the extrusion of the steel material. In the discharging stage, the forming groove 14 can promote the sliding of the ingot from the top of the second pressing plate 13;

[0037] The ingot falls into the groove of the discharging groove 20 and slides down, realizing the guiding of the ingot to facilitate the transfer of the ingot by the transportation equipment. When the ingot slides down from the top of the discharging groove 20, the ingot will push the roller 21 to drive the rotating shaft 22 and the paddle 23 to rotate. By stirring the liquid pre-stored in the storage cylinder 24 with the paddle 23, taking non-Newtonian liquid as an example, the rotation speed of the rotating shaft 22 is restricted. The outer surface of the roller 21 is provided with anti-slip lines to ensure the pushing effect of the ingot on the roller 21. By installing a plurality of rollers 21 at the top of the discharging groove 20 to form a deceleration channel, the slow sliding of the ingot can be ensured. By setting the first inserting block 26 and using the first inserting slot to limit the first inserting block 26, the storage cylinder 24 is kept stationary, while the second inserting block 27 falls into the second limiting groove, which can not only ensure the support for the roller 21, but also enable the roller 21 to keep rotating. Furthermore, it is convenient for the roller 21 to rotate relative to the storage cylinder 24 to stir the liquid.
