Description

Technical Field

[0001] This utility model relates to the field of scrap steel pressing, and specifically to a stepped scrap steel pressing device. Background Technology

[0002] With increasing environmental awareness, protecting the Earth and the environment is receiving more and more attention. Waste recycling not only improves people's living environment but also reduces human damage to the planet. In scrap steel recycling, collection efficiency is low, requiring compression to improve space utilization. Scrap steel flattening machines are used to save space. However, in practice, it has been found that flattening large quantities of scrap steel at once requires a flattener with higher pressure parameters, resulting in high equipment costs. If a flattener with lower pressure parameters is used to flatten large quantities of scrap steel at once, some areas may not be flattened properly.

[0003] Therefore, in order to overcome the shortcomings of existing technologies, it is necessary to design a simple, low-cost, and effective stepped scrap steel pressing device. Utility Model Content

[0004] This invention provides a stepped scrap steel pressing device to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: A stepped steel pressing device includes a stepped pressing bin, a pressing mechanism, and an ejection mechanism. The stepped pressing bin includes a primary pressing zone, a secondary pressing zone, and a tertiary pressing zone arranged in a stepped manner downwards. A feed inlet is provided on the left side of the upper end of the primary pressing zone. The pressing mechanism includes a hydraulic cylinder and a pressure plate. The pressure plate is located at the lower end of the hydraulic cylinder. The three sets of pressing mechanisms are respectively located above the primary pressing zone, the secondary pressing zone, and the tertiary pressing zone. A baffle plate is provided on the left side of the pressure plate of the pressing mechanism above the secondary pressing zone and the tertiary pressing zone. The three sets of ejection mechanisms are respectively located on the left side of the primary pressing zone, the secondary pressing zone, and the tertiary pressing zone. The ejection mechanism includes a hydraulic cylinder and a push plate. The push plate is located at the right end of the hydraulic cylinder.

[0006] In a further improvement, the lower end of the push plate at the corresponding position is attached to the bottom of the primary pressing zone, the secondary pressing zone, and the tertiary pressing zone.

[0007] As a further improvement, a discharge conveyor belt is provided on the right side of the three-stage pressing zone of the stepped pressing hopper.

[0008] As a further improvement, a frame is provided at the lower end of the stepped pressing hopper.

[0009] In a further improvement, the left side of the primary pressing zone, the secondary pressing zone, and the tertiary pressing zone in the stepped pressing chamber is provided with a fixed support frame, and the second hydraulic cylinder is installed on the support frame.

[0010] Compared with existing technologies, the advantages of this utility model's stepped scrap steel pressing device are as follows:

[0011] By using a step-by-step compression method, the use of high-pressure compression machines is avoided, reducing equipment procurement and operating costs. Step-by-step compression ensures that scrap steel is fully compressed in each compression zone, avoiding localized under-compression and improving the compression effect. Scrap steel after step-by-step compression has a smaller volume, higher space utilization, and is easier for subsequent transportation and storage. Attached Figure Description

[0018] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A stepped scrap steel pressing device includes: a stepped pressing bin, a pressing mechanism 2, and an ejection mechanism 3. The stepped pressing bin includes a primary pressing zone 11, a secondary pressing zone 12, and a tertiary pressing zone 13 arranged in a stepped manner downwards. The primary pressing zone 11 has a feed inlet on the left side of its upper end. The pressing mechanism 2 includes a hydraulic cylinder 21 and a pressure plate 22. The pressure plate 22 is located at the lower end of the hydraulic cylinder 21. The three sets of pressing mechanisms 2 are respectively located above the primary pressing zone 11, the secondary pressing zone 12, and the tertiary pressing zone 13. The pressure plate 22 of the pressing mechanism 2 above the secondary pressing zone 12 and the tertiary pressing zone 13 has a baffle plate 23 on the left side of its pressure plate 22. The three sets of ejection mechanisms 3 are respectively located on the left side of the primary pressing zone 11, the secondary pressing zone 12, and the tertiary pressing zone 13. The ejection mechanism 3 includes a hydraulic cylinder 31 and a push plate 32. The push plate 32 is located at the right end of the hydraulic cylinder 31.

[0021] like Figures 1-3 As shown, the working principle of this utility model is as follows: The device adopts a stepped pressing bin, divided into a primary pressing zone, a secondary pressing zone, and a tertiary pressing zone. Scrap steel gradually enters the subsequent pressing zones starting from the primary pressing zone. Each pressing zone is equipped with a pressing mechanism above it, which compresses the scrap steel step by step by driving the pressing plate through a hydraulic cylinder. This step-by-step compression method avoids the high pressure required to compress a large amount of scrap steel at once, reducing equipment costs. Each pressing zone has an ejection mechanism on its left side, which pushes the compressed scrap steel out through a hydraulic cylinder, ensuring that the scrap steel can smoothly enter the next pressing zone or be finally discharged from the device.

[0022] The baffle plate on the left side of the pressure plate of the pressing mechanism above the secondary and tertiary pressing zones ensures that when the pressing mechanism in the primary pressing zone presses down on the scrap steel, the scrap steel remains stable within the primary pressing zone and does not detach; and when the pressing mechanism in the secondary pressing zone presses down on the scrap steel, the scrap steel remains stable within the secondary pressing zone and does not detach.

[0023] As a further preferred embodiment, the lower end of the push plate 32 at the corresponding position is attached to the bottom of the primary pressing area 11, the secondary pressing area 12 and the tertiary pressing area 13. The lower end of the push plate is attached to the bottom of the pressing area, which can ensure that the contact area between the push plate and the scrap steel is maximized when the scrap steel is pushed out, and avoid the scrap steel from getting stuck or not being pushed out completely during the pushing process.

[0024] As a further preferred embodiment, the right side of the three-stage pressing zone 13 of the stepped pressing silo is provided with a discharge conveyor belt 4, which is used to directly transport the finally compressed scrap steel to the subsequent process to realize automated continuous production.

[0025] As a further preferred embodiment, the lower end of the stepped pressing hopper is provided with a frame 5, which provides a stable installation foundation for the stepped pressing hopper, the pressing mechanism and the ejection mechanism, ensuring the stability and reliability of the device during operation.

[0026] As a further preferred embodiment, a support frame 51 is fixed on the left side of the primary pressing zone 11, the secondary pressing zone 12 and the tertiary pressing zone 13 in the stepped pressing bin. The second hydraulic cylinder 31 is installed on the support frame 51. The support frame is used to install the second hydraulic cylinder of the ejection mechanism to ensure that the installation position of the second hydraulic cylinder is accurate and stable, and can accurately drive the push plate to perform the ejection operation.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
