Description

Technical Field

[0001] This utility model relates to the field of graphitization processing technology, and in particular to a material suction crane and a graphitization production system. Background Technology

[0002] After the graphitization furnace process is completed, the product material needs to be removed. Currently, this is done using an overhead crane. The crane has three degrees of freedom of movement in the X, Y, and Z directions. A suction pipe is installed on the crane, with one end serving as the suction head and the other end connected to a hopper. Because the material reaches a high temperature after processing, it is easily oxidized during the removal process, which will affect its later use.

[0003] In addition, existing overhead cranes integrate vehicle-mounted silos and ash silos, with a cooler installed between the silos and the ash silos. During use, more than 90% of the material enters the silos, while the remaining 10% enters the ash silos with the air. The material and air entering the ash silos can be cooled by the cooler, but the material entering the silos cannot be cooled, resulting in a higher temperature in the silos, which will lead to oxidation.

[0004] In addition, the existing hoppers integrated into the overhead cranes are temporary storage hoppers. When the hoppers are full, the overhead cranes need to be activated to move the hoppers to the unloading area. At this time, the material suction and unloading operation is suspended, creating a break in material discharge. During the pause, impurities may enter the material, affecting its quality, and material spillage may also occur, impacting the environment.

[0005] Furthermore, the existing overhead crane's suction pipe lacks a cleaning device, causing materials to clump together inside the furnace. Manual assistance is required to break up the clumps before the material can be completely sucked up. Additionally, when the suction pipe is inserted into the material, it may become blocked by the material, preventing normal material suction. Moreover, the equipment lacks a large particle filtration device, which can cause large particles to wear down the pipes, impact the filter bags in the ash hopper, shorten their lifespan, and jam the blower, rendering the equipment inoperable. Utility Model Content

[0006] The purpose of this invention is to provide a suction crane and graphitization production system that can cool down materials in a silo.

[0007] The technical solution of this utility model is: a material suction crane, including a main trolley and a trolley mounted on the main trolley and capable of displacement along the X direction, characterized in that it further includes a material cooler, a catcher, a suction pipe, and a conveying pipe. The material cooler is mounted on the trolley. One end of the catcher is a second inlet, and the other end of the catcher is a outlet. The suction pipe is vertically mounted on the trolley. The upper end of the suction pipe is connected to the second inlet through a first pipe, and the lower end of the suction pipe forms a suction head. The outlet is connected to the material cooler through a second pipe, and one end of the conveying pipe is connected to the material cooler.

[0008] Preferably, the trap is provided with a filter screen, which is arranged between the discharge port and the second inlet.

[0009] Preferably, the lower end of the catcher is provided with a discharge cylinder, which is located between the filter screen and the second inlet, and at least one valve is provided on the discharge cylinder.

[0010] Preferably, the trolley is also equipped with a third hopper, the discharge cylinder is located above the third hopper, and a third pipe is connected to the bottom of the third hopper.

[0011] Preferably, the suction pipe includes a fixed outer pipe and a telescopic inner pipe. The fixed outer pipe is vertically installed on the trolley. The upper end of the fixed outer pipe is connected to the first pipe. The lower end of the fixed outer pipe is telescopically fitted with the telescopic inner pipe. The lower end of the telescopic inner pipe is provided with the suction head.

[0012] Preferably, a plurality of air blowing pipes are arranged on the outer periphery of the suction head, and the plurality of air blowing pipes extend along the axial direction of the suction pipe.

[0013] Preferably, a C-shaped wall is connected to the outer wall of the suction head, and an air passage is formed between the C-shaped wall and the suction head. An air inlet is provided at the upper end of the C-shaped wall, and an air replenishment port is formed through the bottom of the C-shaped wall. The air inlet, the air passage, and the air replenishment port are connected.

[0014] Preferably, the conveying pipe includes a second hose, a fourth pipe, a first hose, and a fifth pipe connected in sequence, with the end of the second hose away from the fourth pipe connected to the material cooler.

[0015] This utility model also provides a graphitization production system, including a graphitization furnace, a frame located outside the graphitization furnace and extending along the Y direction, a first silo located beside the graphitization furnace, a blower, and the aforementioned suction crane. The trolley of the suction crane is slidably mounted on the frame. The suction head is adapted to the graphitization furnace. The end of the conveying pipe away from the material cooler is connected to the first silo. The blower is connected to the first silo through a sixth pipe.

[0016] Preferably, a second hopper is provided on the side of the graphitization furnace, and the catcher is connected to the second hopper.

[0017] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0018] 1. The suction crane is equipped with a material cooler, which can quickly cool down the suction material, reduce material oxidation, and ensure material quality.

[0019] Second, the hopper is no longer integrated with the suction crane, so that unloading after the hopper is full does not occupy the crane, making the entire material handling process uninterrupted, avoiding contaminants from mixing into the material, and preventing material overflow, thus better ensuring material quality and workshop environment, and improving production efficiency; reducing equipment weight and lowering factory costs.

[0020] 3. An air inlet and an air replenishment port are added to the suction head of the suction pipe. When the suction pipe is buried, air can enter from the air inlet and flow out from the air replenishment port to replenish air, so as to ensure that the suction work is carried out normally.

[0021] IV. The newly added material box cleaning device (such as air blowing pipe) can clean the adhering material on the bottom and side wall of the material box in the graphitization furnace during the normal material suction process, realize the cleaning of the material box at the same time as the material discharge, merge the process flow, and shorten the process time.

[0022] 5. A foreign object catcher is added to the front end of the material suction crane, which can capture large particles, impurities and other foreign objects in the material, to prevent foreign objects from affecting subsequent pipelines, filter bags and airlocks, improve the service life and reliability of the equipment, and reduce the working pressure of downstream equipment.

Detailed Implementation

[0028] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0029] like Figure 1 As shown, the material suction crane 1 provided in this embodiment includes a large trolley 13, a small trolley 15, a material cooler 18, a catcher 19, a suction pipe 30, a conveying pipe 3, and a third hopper 29.

[0030] The bottom of the large vehicle 13 is provided with first traveling wheels 11 that can move in the Y direction. The upper surface of the large vehicle 13 is provided with a second track 8 extending in the X direction. The X and Y directions are perpendicular to each other on the same top projection plane.

[0031] The trolley 15 has second traveling wheels 14 around its bottom. These second traveling wheels 14 are adapted to the second track 8. The trolley 15 is equipped with a material cooler 18, a third hopper 29, and a suction pipe 30. The suction pipe 30 includes a fixed outer tube 16 and a telescopic inner tube 12, both rectangular in shape. The fixed outer tube 16 is vertically mounted on the trolley 15, and its upper end is connected to the first pipe 31. The lower end of the fixed outer tube 16 telescopically fits the telescopic inner tube 12. A suction head 17 is located at the lower end of the telescopic inner tube 12. Because the equipment can move the suction pipe 30 along the length and width of the graphitization furnace, and the telescopic inner tube 12 can extend and retract vertically, the suction head 17 can perform three-dimensional movement, enabling the suction of all materials inside the furnace.

[0032] like Figure 2As shown, multiple air blowing pipes 20 are arranged around the outer periphery of the suction head 17, and the multiple air blowing pipes 20 extend axially along the suction pipe 30. The top end of the air blowing pipe 20 is connected to compressed air, and the bottom end of the air blowing pipe 20 can be equipped with a duckbill nozzle, a rotary nozzle, or a Laval nozzle. When there is adhering material on the bottom and side walls of the graphitization furnace, the compressed air compressor is started to blow compressed air out from the air blowing pipe 20 to disperse the adhering material, which facilitates the suction head 17 to suck up the material and avoids secondary cleaning by manual labor.

[0033] A C-shaped wall 35 is connected to the outer wall of the suction head 17. An air passage is formed between the C-shaped wall 35 and the suction head 17. An air inlet 21 is provided at the upper end of the C-shaped wall 35. An air replenishment port 22 is formed through the bottom of the C-shaped wall 35. The air inlet 21, the air passage and the air replenishment port 22 are connected.

[0034] The bottom opening of the suction head 17 forms a first feed inlet 23. If the material collapses during the suction process, burying the first feed inlet 23 and making it impossible to suck up material, air enters from the air inlet 21 and flows out from the air replenishment port 22 to replenish air and restore the suction head 17 to continue sucking up material.

[0035] like Figure 3 As shown, one end of the trap 19 is a second inlet 24, which is connected to a fixed outer pipe 16 via a first pipe 31. The other end of the trap 19 is an outlet 26, which is connected to the inlet of the material cooler 18 via a second pipe 32. A filter screen 25 is installed inside the trap 19, and the filter screen 25 is inclined towards the side facing the second inlet 24. The filter screen 25 is arranged between the outlet 26 and the second inlet 24. A discharge cylinder 28 is provided at the lower end of the trap 19, and the discharge cylinder 28 is located above the third hopper 29. The discharge cylinder 28 is located between the filter screen 25 and the second inlet 24. Two valves 27 are provided on the discharge cylinder 28. A third pipe 36 for connecting to the second hopper 6 is connected to the lower part of the third hopper 29.

[0036] The collected material enters the trap 19 through the second feed inlet 24. Large particles are intercepted by the filter screen 25 and then enter the discharge cylinder 28. Due to its small particle size, the finished material enters the material cooler 18 for rapid cooling after passing through the filter screen 25, preventing oxidation. The two valves 27 on the discharge cylinder 28 open and close alternately, reducing pressure loss in the third pipe 36 and ensuring the smooth flow of large particles. The cooled material in the material cooler 18 enters the conveying pipe 3.

[0037] like Figure 4As shown, this utility model also provides a graphitization production system, including a graphitization furnace 2, a frame 37 located outside the graphitization furnace 2 and extending along the Y direction, a first hopper 5 located beside the graphitization furnace 2, a blower 4, a second hopper 6, and the aforementioned suction crane 1.

[0038] The upper surface of the frame 37 is provided with a first track 7. The first traveling wheel 11 on the trolley 13 is adapted to the first track 7. The third pipe 36 is connected to the second hopper 6 via a flexible hose (not shown).

[0039] The conveying pipe 3 includes a second flexible hose 10, a fourth pipe 33, a first flexible hose 9, and a fifth pipe 34 connected in sequence. The end of the second flexible hose 10 away from the fourth pipe 33 is connected to the material cooler 18. The end of the fifth pipe 34 away from the first flexible hose 9 is connected to the first hopper 5. The blower 4 is connected to the first hopper 5 via a sixth pipe 38. Product material enters the first hopper 5 from the conveying pipe 3, completing the furnace discharge process.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
