Description

Technical Field

[0001] The present invention relates to the technical field of presses, and more particularly to a metal crushing and briquetting recovery device. Background Art

[0002] like Figure 1 The figure shows a commercially available integrated crushing and briquetting machine, which is mainly composed of a crushing device and a briquetting device. The discharge end of the crushing device is directly connected to the feed end of the briquetting device to save equipment volume. However, there are the following problems in actual application:

[0003] 1. Because the crushing device is directly connected to the briquetting device, the crushing device cannot continue to feed materials when the briquetting device is briquetting. If materials continue to be fed, there is a risk that the materials will fall into the interior of the hydraulic equipment. When briquetting, the push rod of the hydraulic equipment will be exposed below the discharge end of the crushing device. Even if materials are not fed, the residual materials remaining in the crushing device will fall onto the push rod of the hydraulic equipment or into the interior of the hydraulic equipment. When the hydraulic equipment is reset, the residual materials may cause irreversible damage to the push rod of the hydraulic equipment or the hydraulic equipment.

[0004] 2. Because the crushing device cannot be fed when the briquetting device is briquetting, the crushing device is idling at this time, which will cause energy waste.

[0005] 3. Because the crushing device is directly connected to the briquetting device, it is necessary to manually control the amount of material added. If too much material is added, the material will fall into the briquetting device or onto the push rod when the briquetting device is briquetting. As mentioned in point 1, if the amount added is small, the volume of the molded material may be small, so it is difficult to unify the size of the molded material.

[0006] 4. After briquetting is completed, it is necessary to re-feed the crushing device. During this period, it will take too long to fill the cavity of the briquetting device, resulting in low processing efficiency.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0035] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0036] like Figure 1-Figure 7 As shown, the present invention provides a metal crushing and briquetting recovery device, comprising: a crushing device 1, a briquetting device 2 connected to the crushing device 1 through a conveying channel; the crushing device 1 and the briquetting device 2 are both arranged on a frame, the crushing device 1 is located above the briquetting device 2, one end of the conveying channel is connected to the discharge end of the crushing device 1, and the other end is connected to the feed end of the briquetting device 2, a feed regulating device is arranged on the conveying channel, the feed regulating device is used to control the amount of material entering the briquetting device 2, and the conveying channel is used to transport and temporarily store the material provided by the crushing device 1. The crushing device 1 is composed of a feed hopper and a crusher driven by a first driving device, the feed hopper is located at the top of the crusher, forming the feed end of the crushing device 1, the bottom of the crusher is the discharge end of the crushing device 1, and is connected to the feed end of the conveying channel, the feed hopper, the first driving device and the crusher are all existing technologies, as long as the crushing device 1 can realize material crushing. The briquetting device 2 is composed of at least one hydraulic device and a cavity for placing materials. There may also be two hydraulic devices, and the two hydraulic devices are arranged opposite to each other. The top of the cavity is the feed end, and the discharge end of the conveying channel is connected to the feed end of the cavity. The hydraulic device is used to extrude the material in the cavity. Both the hydraulic device and the cavity are prior art, as long as the briquetting device 2 can extrude the material.

[0037] The working principle and beneficial effects of the above technical solution: Through the design of the above structure, the crushing device 1 crushes the bulk material, and the crushed material will be transported to the briquetting device 2 through the conveying channel. When the material in the briquetting device 2 is filled, the feeding adjustment device will block the material in the conveying channel. At this time, the crushing device 1 does not need to be shut down and can continue the material crushing operation. Under the blocking of the feeding adjustment device, the material will be temporarily stored in the conveying channel to prevent the material from falling into the briquetting device 2 that is performing the briquetting operation. When the briquetting is completed, the briquetting device 2 is reset, and the formed material is taken out from the briquetting device 2 through the manipulator or the drop port (set at the bottom of the cavity). After that, the feeding adjustment device is reset, and the material temporarily stored in the transport channel will fall into the briquetting device 2, and then the above operation can be repeated. By setting the feeding adjustment device, the crushing device 1 does not need to be shut down during the operation of the briquetting device 2. Continuous crushing can prepare materials for the next extrusion of the briquetting device 2 in advance. After the formed material is taken out from the briquetting device 2, the material can be quickly filled, reducing the filling time of the material and improving the processing efficiency. At the same time, because the material will not be blocked by the feed regulating device during the process of the briquetting device 2 squeezing the material, it is prevented from falling into the hydraulic device of the briquetting device 2 and causing damage to the hydraulic device.

[0038] As a first embodiment of the present invention, the conveying channel is a first channel 3, the first channel 3 is inclined, and there is a non-zero angle between the first channel 3 and the horizontal plane, such as Figure 2As shown, the first channel 3 is provided with a first through hole, and the first through hole is located on the side wall of the first channel 3 away from the briquetting device 2. Usually, the first channel 3 adopts a channel with a rectangular cross section, and the first through hole is located at the top of the first channel 3. The feeding adjustment device extends from the first through hole to the first channel 3. When conveying materials into the briquetting device 2, the feeding adjustment device does not close the first channel 3; when the conveying of materials to the briquetting device 2 stops, the feeding adjustment device moves into the first channel 3 and abuts against the inner wall of the first channel 3 to close the first channel 3. In the first embodiment, the feeding adjustment device is a first adjustment device 4, which is composed of a telescopic device 41, a first shielding member 43 connected to the telescopic device 41 through a transmission rod 42, and a first linkage mechanism 44 rotatably connected to the transmission rod 42. The telescopic device 41 can be a telescopic rod driven by a motor or hydraulic pressure, as long as it is an existing technology or a commercially available product that can achieve the telescopic function. The end of the telescopic device 41 is rotatably connected to one end of the transmission rod 42, and the other end of the transmission rod 42 is rotatably connected to the first shielding member 43. The first shielding member 43 extends into the first channel 3 through the first through hole. When conveying materials to the briquetting device 2, the end of the first shielding member 43 does not close the first channel 3. When the conveying of materials to the briquetting device 2 stops, the transmission rod 42 can drive the first shielding member 43 to move under the drive of the telescopic device 41. The first shielding member 43 extends into the first channel 3 until it abuts against the inner wall of the first channel 3 and closes the first channel 3, thereby preventing the material from entering the briquetting device 2.

[0039] As one of many embodiments, the first linkage mechanism 44 is composed of a first connecting rod and two axial connectors arranged at both ends of the first connecting rod. One end of the first connecting rod is rotatably connected to the transmission rod 42 through the axial connector, and the other end is connected to the frame through another axial connector, so that the transmission rod 42 is supported by the first connecting rod.

[0040] Further, the first shielding member 43 is composed of a mounting shaft 431 rotatably connected to the end of the transmission rod 42, and an arc-shaped bucket 432 detachably connected to the mounting shaft 431. In order to reduce the number of motors or hydraulic equipment used, the cross-section of the first through hole is an arc-shaped hole. The first through hole is adapted to the shape of the arc-shaped bucket 432, and when conveying materials into the briquetting device 2, the arc-shaped bucket 432 is always located in the first through hole, and the first through hole can provide a position limit for the arc-shaped bucket 432.

[0041] When the arc-shaped bucket 432 moves into the conveying channel through the first through hole, the movement trajectory of the end of the arc-shaped bucket 432 abutting against the first channel 3 is an arc-shaped arc bent toward the crushing device 1, such as Figure 2-Figure 4As shown, a plurality of grooves are provided on the side of the arc-shaped bucket 432 facing the briquetting device 2, so that the side of the arc-shaped bucket 432 facing the briquetting device 2 forms a "toothed rake" shape, as shown in FIG. Figure 4 As shown, when the crushed material is temporarily stored in the first channel 3 and is compressed into blocks, the arc bucket 432 can effectively cut the block materials, and the "tooth rake" on the side of the arc bucket 432 facing the briquetting device 2 can hook the filamentary materials that have not fallen into the briquetting device 2 (such as steel wire, iron wire, etc. that have not been torn off by the crushing device 1).

[0042] In the first embodiment, we use a simple arc bucket 432 design to block the material in the first channel 3. Although this embodiment adopts an "excavating" action similar to that of an excavator (the motion trajectory of the end of the arc bucket 432 is an arc that bends toward the crushing device 1), it can effectively block the material, and the "tooth rake" design of the arc bucket 432 prevents the filamentary material from falling into the running briquetting device 2. However, in actual application, non-filamentary materials attached to the "tooth rake" of the arc bucket 432 will still fall into the briquetting device 2. Although the degree of damage to the briquetting device 2 by the broken slag is not high compared to the steel wire, we still made further optimization design for the problem of material leakage, and effectively prevented the material from falling into the running briquetting device 2 when the material is stopped from being transported to the briquetting device 2. For this reason, we provide a second embodiment.

[0043] In this embodiment, the conveying channel is a second channel 5, which is composed of a falling section 51 arranged in the vertical direction, and a sliding section 52 with a non-zero angle between the falling section 51 and the falling section 51. The top of the falling section 51 is connected to the discharge end of the crushing device 1 to prevent the crushed material from accumulating at the discharge end of the crushing device 1. The bottom of the falling section 51 is connected to the top of the sliding section 52, and the material can slide from the sliding section 52 into the cavity of the briquetting device 2.

[0044] Further, the feeding adjustment device is a second adjustment device, and the second adjustment device is composed of a blocking device 6 and a receiving device 7. A second through hole is provided on the sliding section 52, and the second through hole is located on the side wall of the sliding section 52 away from the briquetting device 2. Usually, the cross-section of the second channel 5 is rectangular, and the second through hole is located at the top of the second channel 5. The blocking device 6 is composed of a limiting member 61 arranged on the outer wall of the sliding section 52, and a second shielding member 62 arranged in the limiting member 61. The second shielding member 62 is movably connected to the limiting member 61, and the second shielding member 62 is connected to the second driving device. As one of many embodiments, the second shielding member 62 can be a plate-like structure, and the limiting member 61 can be a slide groove, such as Figure 5-Figure 7As shown, as long as the blocking device 6 can realize the closing and opening functions of the second channel 5. Because the receiving device 7 is provided in this embodiment, the second shielding member 62 does not need to be set as the arc-shaped "tooth rake" shape of the first shielding member 43, but the first shielding member 43 can still be used as the second shielding member 62, and the second shielding member 62 extends from the second through hole to the inside of the sliding section 52. The receiving device 7 is movably connected to the outer wall of the second adjusting device and selectively closes the discharge end of the sliding section 52.

[0045] Furthermore, the receiving device 7 is composed of a fixing member 71 connected to the outer wall of the second channel 5, a second linkage mechanism 72 movably connected to the fixing member 71, and a receiving member 73 rotatably connected to the outer wall of the sliding section 52. As one of many embodiments, the second linkage mechanism 72 is composed of a third driving device and a second connecting rod, one end of the second connecting rod is connected to the third driving device, and the other end passes through the fixing member 71 and is rotatably connected to the receiving member 73 through an axis connecting member, such as Figure 5-Figure 7 As shown, the receiving member 73 is composed of an arc segment 731 rotatably connected to the second connecting rod, and a straight segment 732;

[0046] When conveying materials to the briquetting device 2, the straight section 732 is connected to the sliding section 52, and the two are located on the same central axis. The temporarily stored materials can reach the straight section 732 from the sliding section 52, and are conveyed into the cavity of the briquetting device 2 by the straight section 732;

[0047] When the material is stopped from being conveyed to the briquetting device 2, the second shielding member 62 closes the second channel 5, the third driving device drives the second linkage mechanism 72 to move, and the second linkage mechanism 72 drives the receiving member 73 to rotate, because the arc section 731 of the receiving member 73 is connected to the outer wall axis of the sliding section 52, such as Figure 5 As shown, driven by the second linkage mechanism 72, the arc segment 731 rotates relative to the second channel 5, thereby driving the straight segment 732 to move until the arc segment 731 closes the bottom of the sliding segment 52. At this time, the straight segment 732 is located outside the second channel, and the discharge end of the straight segment 732 is higher than the discharge end of the sliding segment 52.

[0048] The arc segment 731 is an arc that bends toward the briquetting device 2. During the rotation of the arc segment 731, the material will fall directly into the arc of the arc segment 731 from the inner bottom wall of the sliding segment 52, thereby preventing the material from being driven by the straight segment 732 to fall into the working briquetting device 2. As the arc segment 731 continues to rotate until it closes the discharge end of the second channel 5, the material that is not blocked by the second blocking member 62 or the leaked material will fall into the arc segment 731. When the arc segment 731 completely closes the second channel 5, the discharge end of the straight segment 732 is higher than the discharge end of the sliding segment 52, which can further prevent the material attached to the straight segment 732 from falling into the working briquetting device 2.
