Description

Technical Field

[0001] This utility model relates to the field of material conveying and production technology, and in particular to a metal waste receiving hopper. Background Technology

[0002] The anode furnace feeding system includes a material receiving hopper. During the metal scrap recycling process, due to the irregular shape and large volume of the metal scrap, there are problems such as large-capacity material deformation, high material spillage loss, insufficient hoisting stability, and poor compatibility with multiple materials.

[0003] The above problems can be solved by squeezing and compressing the metal scrap, but this increases the metal scrap processing steps and reduces the efficiency of metal scrap smelting. Installing limiting structures on both sides of the receiving hopper can limit the receiving hopper during the feeding process and prevent it from deflecting. However, the existing limiting structure is a welded and fixed steel frame, which has poor compatibility with the limiting protrusions on the surface of the anode furnace. In addition, it increases the volume of the receiving hopper during transportation and restricts the movement trajectory of the receiving hopper before and after feeding. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a metal waste receiving hopper that can avoid large shaking during the deflection of the receiving body, which would prevent the metal waste from being stably fed into the anode furnace. At the same time, the retracted telescopic component will not interfere with the normal conveying movement of the receiving body and will not restrict the movement trajectory of the receiving hopper before and after feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal scrap receiving hopper includes a receiving body. A lifting device is provided at the upper end of the receiving body. The lifting device includes a first lifting component located at the tail of the receiving body and a second lifting component located at the middle of the receiving body. A telescopic limiting device is provided at the bottom of the receiving body. The telescopic limiting device is located below the second lifting component. The telescopic limiting device includes two sets of symmetrically arranged telescopic components. The main body of the telescopic component is located inside the horizontal projection plane of the receiving body. After the telescopic component extends, it forms a horizontally protruding limiting structure at the bottom of the receiving body.

[0007] Preferably, the telescopic limiting device includes an installation body, the telescopic component is embedded inside the installation body, and the installation body and the receiving body are detachably connected.

[0008] Preferably, the telescopic assembly includes a first telescopic rod and a second telescopic rod, the first telescopic rod and the second telescopic rod are arranged at intervals, and a limiting area is formed between the first telescopic rod and the second telescopic rod.

[0009] Preferably, the first telescopic rod and the second telescopic rod are arranged at intervals in different horizontal planes, with the second telescopic rod located at a higher height and on the side of the head opening of the receiving body.

[0010] Preferably, both the first and second telescopic rods are pneumatic telescopic rods, and a gas controller is provided inside the mounting body.

[0011] Preferably, there are two gas controllers, each connected to a corresponding telescopic rod.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] Through the above structural design, it is possible to ensure that the lower end of the receiving body is in a relatively constant position for deflection, thus ensuring the stability of the deflection of the receiving body and avoiding large shaking during the deflection process, which would prevent the metal scrap from being stably fed into the anode furnace. At the same time, the retraction of the telescopic component will not interfere with the normal conveying movement of the receiving body and will not restrict the movement trajectory of the receiving hopper before and after feeding.

Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] To address the problems in the background technology, please refer to the appendix. Figure 1 -Appendix Figure 5 A metal scrap receiving hopper includes a receiving body 100. A lifting device is installed at the upper end of the receiving body 100. The lifting device includes a first lifting assembly 200 located at the rear of the receiving body 100 and a second lifting assembly 300 located in the middle of the receiving body 100. A hoisting trolley is installed at the upper end of the first lifting assembly 200 and the second lifting assembly 300. Controlling the hoisting trolley moves the first lifting assembly 200 and the second lifting assembly 300, causing the receiving body 100 below to move synchronously to different positions, realizing the loading, transportation, and disposal of metal scrap. Controlling the second lifting assembly 300 to descend, while the first lifting assembly 200 remains in the same position, allows the receiving body 100 to be in a lower position. Figure 2 As shown, the main body 100 is tilted as a whole to allow for the loading of metal scrap.

[0023] A telescopic limiting device 400 is provided at the bottom of the receiving body 100. The telescopic limiting device 400 is located below the second lifting assembly 300. The telescopic limiting device 400 includes two sets of symmetrically arranged telescopic assemblies 420. The main body of the telescopic assembly 420 is located inside the horizontal projection plane of the receiving body 100. After the telescopic assembly 420 extends, it forms a horizontally protruding limiting structure at the bottom of the receiving body 100.

[0024] During the metal scrap feeding process, the telescopic component 420 is extended to form a prominent limiting structure that can abut against the limiting protrusion on the surface of the anode furnace. During the deflection of the receiving body 100, the telescopic component 420 limits the position of the lower end of the receiving body 100, ensuring that the lower end of the receiving body 100 is in a relatively constant position during deflection, thus ensuring the stability of the deflection of the receiving body 100 and preventing large shaking during the deflection of the receiving body 100, which would cause the metal scrap to be unable to be stably fed into the anode furnace.

[0025] Before or after the metal scrap is fed into the conveying process, the telescopic component 420 is controlled to retract. After retraction, the telescopic component 420 is hidden at the bottom of the receiving body 100. There are no protruding structures on both sides of the receiving body 100, and the volume of the receiving body 100 does not change. It will not interfere with the normal conveying movement of the receiving body 100, and will not restrict the movement trajectory of the receiving hopper before and after feeding.

[0026] In summary, the above structural design ensures that the lower end of the receiving body 100 is in a relatively constant position for deflection, thus ensuring the stability of the deflection of the receiving body 100 and preventing large shaking during the deflection process, which would cause the metal scrap to be unable to be stably fed into the anode furnace. At the same time, the retracted telescopic component 420 will not interfere with the normal conveying movement of the receiving body 100 and will not restrict the movement trajectory of the receiving hopper before and after feeding.

[0027] Specifically, the telescopic limiting device 400 includes an installation body 410, a telescopic component 420 embedded inside the installation body 410, and a detachable connection between the installation body 410 and the receiving body 100. The installation body 410 can be fixedly connected to the receiving body 100 by bolts. The position of the installation body 410 at the bottom of the receiving body 100 is opposite to the vertical position of the second lifting component 300 above it, which can play a good limiting effect in the process of controlling the deflection of the receiving body 100.

[0028] The telescopic assembly 420 includes a first telescopic rod 421 and a second telescopic rod 422, which are arranged at intervals, and a limiting area 4001 is formed between the first telescopic rod 421 and the second telescopic rod 422.

[0029] With the above structural setup, two sets of limiting structures can be formed, which can limit the movement on both sides of the anode furnace protrusion, further preventing the container body 100 from shaking during the placement process. The distance between the two sets of telescopic rods should be greater than the width of the anode furnace surface protrusion to ensure that the container body 100 deflects normally.

[0030] The aforementioned telescopic end is circular. During the deflection process, the arc-shaped surface of the telescopic end faces the protrusion of the anode furnace. The curvature of the arc does not change during the deflection process, further ensuring the stability of the main body 100 during the deflection process.

[0031] Furthermore, the first telescopic rod 421 and the second telescopic rod 422 are arranged at intervals in different horizontal planes. When the bottom of the receiving body 100 is horizontal, the second telescopic rod 422 is located at a higher height and is located on the side of the head opening of the receiving body 100.

[0032] Through the above structural design, during the deflection of the main body 100, the heights of the first telescopic rod 421 and the second telescopic rod 422 gradually change, with the height of the second telescopic rod 422 gradually decreasing and the height of the first telescopic rod 421 gradually increasing. This ensures that the telescopic ends of the two telescopic rods are always in sync with the protrusion, preventing detachment.

[0033] Both the first telescopic rod 421 and the second telescopic rod 422 are pneumatic telescopic rods. A gas controller is installed inside the mounting body 410. The gas controller can be an air pump. The pneumatic telescopic rod is an elastic telescopic rod with an air outlet. By continuously pumping gas into the pneumatic telescopic rod, the extension of the pneumatic telescopic rod can be controlled. After the pumping stops, the gas inside the elastic telescopic rod is squeezed out under the action of elasticity, thereby realizing the contraction control of the telescopic rod.

[0034] Alternatively, a gas control structure with pumping and evacuation functions can be selected, which controls the extension and retraction of the pneumatic telescopic rod by controlling the gas flow state.

[0035] Furthermore, there are two gas controllers, each connected to a corresponding telescopic rod. Through the above structural design, the two telescopic rods can be extended sequentially and retracted synchronously. The system can automatically adjust according to the placement and transportation status of the receiving body 100. At the same time, detection cameras can be installed around the receiving body 100 to determine the position between the telescopic rod and the protrusion on the surface of the anode furnace, ensuring the stability and accuracy of the extension of the telescopic rod.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
