Description

Technical Field

[0001] This utility model relates to the field of material handling, and in particular to a feeder and crushing system. Background Technology

[0002] A feeder is a piece of equipment in a material handling system, positioned before the crusher in the process. It assists the crusher in completing its crushing task, primarily used for pressing materials to aid crushing and removing uncrushable materials. When the crusher processes flammable, explosive, or other hazardous materials, the crushing chamber needs to be a sealed space. Because the crusher and feeder are open spaces, gate valves need to be added to the lower part of the crusher and the upper part of the feeder. Closing both gate valves simultaneously creates a sealed crushing zone. However, existing feeders do not have flanges compatible with standard gate valves, and the feeder lacks explosion-proof process interfaces. Therefore, a crushing chamber needs to be added between the feeder and the upper gate valve, connecting the gate valve to the feeder. Furthermore, features such as... The process interfaces, such as nitrogen charging interface, exhaust interface, oxygen analysis interface, and fire protection interface, replace oxygen by filling the crushing chamber with nitrogen, thereby controlling the oxygen concentration within a safe range. However, adding a crushing chamber between the feeder and the upper gate valve results in an excessively high height from the flange surface of the upper gate valve to the floor where the crusher is located, causing the overall height of the building where the crushing system is located to fail to meet relevant building height regulations. At the same time, the process pipes are located at the inevitable passage of materials, making it difficult to avoid pipe blockage. If the explosion relief cylinder is blocked by materials, it is difficult to prevent the rupture disc from being damaged by the materials, and the effective cross-section of the explosion relief channel is reduced. In addition, the large volume of the sealed crushing chamber requires the configuration of larger-sized rupture discs, which are difficult to match with the rupture discs in other chambers of the crushing system.

[0057] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0058] like Figures 1 to 8 As shown, an embodiment of this utility model provides a feeder, comprising:

[0059] The feeder body 1 has a receiving chamber inside which a feeder pusher assembly is provided, and the feeder pusher assembly is slidably connected to the side wall of the receiving chamber of the feeder body 1.

[0060] A crushing zone 2 is provided on one side of the feeder body 1, and a crushing chamber communicating with the receiving chamber is provided in the crushing zone 2.

[0061] One end of the feeder body 1 is provided with a feeder outlet that is connected to the feed inlet of the crusher, and the feeder outlet is connected to the receiving chamber.

[0062] The crushing zone 2 is provided with a feeder inlet that communicates with the crushing chamber, and the feeder inlet is connected to the upper gate.

[0063] In this embodiment, both the outer shell of the feeder body 1 and the outer shell of the crushing zone 2 are welded together. In use, the material to be crushed 10 enters the crushing chamber from the feeder inlet. Then, the feeder pusher assembly within the chamber compresses and presses the material, allowing it to pass through the feeder outlet into the crusher inlet. This also facilitates easier tearing and shearing of the material by the crushing blades, improving the crusher's material processing efficiency. In this embodiment, by integrating a crushing zone 2 on one side of the feeder body 1, the feeder not only provides crushing assistance but also feeding and storage functions, enriching its functionality and making it suitable for various crushing scenarios, such as... Figure 8 The shown elevator-driven horizontal feeding crushing system with a crushing bin feeder can be used for, for example... Figure 7 The vertical feeding crushing system with a crushing bin feeder shown in the figure greatly reduces the vertical dimensions of the crushing system, effectively reducing the overall height of the crushing system and increasing its adaptability to building space.

[0064] In an optional embodiment of this utility model, the feeder further includes:

[0065] An explosion vent 20 is provided on the crushing zone 2 and located between the feeder inlet and the feeder body 1.

[0066] In this embodiment, the explosion vent 20 is used for explosion venting when handling flammable and explosive materials. By placing the explosion vent 20 between the feeder inlet and the feeder body 1, it is possible to effectively prevent the material entering during the feeding process from clogging the explosion vent cylinder. At the same time, the explosion vent 20 is placed on the upper part of the shell of the crushing zone 2, keeping it away from the material being crushed, thus preventing the rupture membrane from being damaged by the splashed material.

[0067] In an optional embodiment of this utility model, the feeder pusher assembly includes:

[0068] A first slide rail assembly and a second slide rail assembly are disposed on the side wall of the receiving chamber of the feeder body 1, and the first slide rail assembly and the second slide rail assembly are disposed opposite to each other on the side wall of the receiving chamber;

[0069] A feeder pusher head 41 is disposed on the first slide rail assembly and the second slide rail assembly and is slidably connected to the first slide rail assembly and the second slide rail assembly;

[0070] The pusher cylinder 42 has one end connected to the top of the feeder body 1 and the other end connected to the feeder pusher 41.

[0071] In a preferred embodiment, the feeder pusher assembly further includes: safety pins 45 disposed on the feeder body 1 and located on both sides of the feeder pusher 41. The safety pins 45 are used to fix the feeder pusher 41 during the transportation or installation of the feeder, preventing the feeder pusher 41 from sliding due to gravity during installation or transportation. The safety pins 45 consist of a flange plate and pins on both sides, with different lengths on both sides. During normal operation, the shorter pin is installed inward, and the shorter pin does not protrude from the inner wall of the feeder body 1, thus not affecting the up-and-down movement of the pusher. During factory assembly and transportation, the longer pin is installed inward, and the pin will protrude from the inner wall of the feeder body, thereby restricting the position of the feeder pusher to a specific position and avoiding safety accidents caused by the pusher moving up and down due to its own weight.

[0072] In this embodiment, one end of the pusher cylinder 42 is fixedly connected to the top of the feeder body 1 via a first fixing pin 421, and the other end is connected to the feeder pusher 41 via a second fixing pin 422. The feeder pusher 41 has sliding grooves on both sides. The feeder pusher 41 is engaged with the first and second slide rail assemblies via these grooves, and the extension and retraction of the pusher cylinder 42 drives the feeder pusher 41 to slide on the first and second slide rail assemblies. The feeder pusher 41 is located on one side of the feeder outlet and is used to compress the material entering the crushing chamber, pressing the material to the feed inlet of the crusher for crushing.

[0073] In an optional embodiment of this utility model, the first slide rail assembly includes:

[0074] The first upper slide rail 431 and the first lower slide rail 432 that engages with the first upper slide rail 431.

[0075] The second slide rail assembly includes:

[0076] The second upper slide rail 441 and the second lower slide rail 442 that engages with the second upper slide rail 441.

[0077] In this embodiment, one end of the first upper slide rail 431 is provided with a protrusion, and one end of the first lower slide rail 432 is provided with a groove that engages with the protrusion. The first upper slide rail 431 and the first lower slide rail 432 are engaged by the protrusion and the groove. In this embodiment, since the feeder pusher head 41 mainly slides on the first lower slide rail 432, the first lower slide rail 432 is prone to wear and damage. The segmented design of the first slide rail assembly and the second slide rail assembly facilitates later maintenance. During maintenance, any one of them can be removed and replaced individually without disassembling the whole assembly.

[0078] In an optional embodiment of this utility model, the feeder further includes:

[0079] A feeder inspection port is provided on the outer shell on the other side of the feeder body 1 and communicates with the receiving chamber. The feeder inspection port is blocked by the feeder back door 3.

[0081] In a preferred embodiment, the feeder back door 3 is provided with an inspection window 31;

[0082] In this embodiment, the discharge port is used to discharge uncrushable material 32 from the crushing chamber; the feeder back door 3 is fixed to the feeder body 1 by bolts; the feeder inspection port is located on one side of the feeder pusher assembly for inspection of the feeder pusher assembly. When the feeder pusher assembly needs to be inspected, it can be inspected directly through the inspection window 31 or by directly removing the feeder back door 3.

[0083] In an optional embodiment of this utility model, the discharge assembly includes:

[0084] The discharge gate 51 is located at the discharge port, and one end of the discharge gate 51 is rotatably connected to the outer shell of the feeder body 1.

[0085] The discharge gate cylinder 52 is hinged at one end to one side of the discharge gate 51 and at the other end to the outer shell of the crushing zone 2.

[0086] In this embodiment, when in use, the discharge gate 51 is driven to rotate around the outer shell of the feeder body 1 by the extension and retraction of the discharge gate cylinder 52, thereby realizing the opening or closing of the discharge port.

[0087] In an optional embodiment of this utility model, the discharge assembly further includes:

[0088] A limiting protrusion 54 is provided on the outer shell of the feeder body 1;

[0089] Safety rod 53, one end of which is coaxially fixed to one end of the discharge gate cylinder 52 on one side of the discharge gate 51, and the other end is set on the outer shell of the feeder body 1 and rotatably connected to the outer shell of the feeder body 1, and the end is provided with a slot that engages with the limiting protrusion 54.

[0090] In this embodiment, during installation, the side wall of the other end of the safety rod 53 rests on the limiting protrusion 54, and the end is rotatably connected to the outer shell of the feeder body 1. In use, the side wall of the other end of the safety rod 53 can slide relative to the limiting protrusion 54. The safety rod 53 and the discharge gate cylinder 52 move simultaneously. When the discharge gate cylinder 52 extends or retracts, one end of the safety rod 53 moves with the discharge gate cylinder 52, while the other end rotates on the outer shell of the feeder body 1, and the other end slides on the limiting protrusion 54. When the discharge gate cylinder 52 extends to the preset position, the slot at the end of the safety rod 53 slides to the position of the limiting protrusion 54 and engages with the limiting protrusion 54. The safety rod 53 is used to support the discharge gate 51 after it is opened, ensuring the safe opening of the discharge gate 51 and preventing the discharge gate 51 from closing unexpectedly after the discharge gate cylinder 52 malfunctions.

[0091] In a preferred embodiment, the discharge assembly further includes:

[0092] A feeder retaining ring 521 is installed at one end of the discharge gate cylinder 52. The feeder retaining ring 521 is located between the discharge gate cylinder 52 and the safety rod 53. It is used to separate the discharge gate cylinder 52 and the safety rod 53 to prevent direct friction and damage when the two are fixed coaxially.
