Description

Technical Field

[0001] The present invention relates to the technical field of graphitization processing, and particularly to a material suction crane and a graphitization production system. Background Art

[0002] After the graphitization furnace is processed, the product materials need to be taken out. The existing method for taking out uses a crane. The crane has degrees of freedom of movement in three directions of X, Y, and Z. A material suction pipe is arranged on the crane. One end of the material suction pipe is a material suction head, and the other end is connected to a material bin. Because the materials are at a relatively high temperature after working, during the material taking process, the high-temperature materials are easily oxidized, which will affect the later use.

[0003] In addition, the existing crane integrates a vehicle-mounted material bin and an ash bin. A cooler is arranged between the material bin and the ash bin, and the ash bin is connected to the cooler. When in use, more than 90% of the materials enter the material bin, and the remaining 10% of the materials will enter the ash bin along with the air. The materials and air entering the ash bin can be cooled by the cooler, while the materials entering the material bin cannot be cooled by the cooler, resulting in a relatively high temperature of the materials in the material bin, and they will be oxidized.

[0004] In addition, the material bin integrated on the existing crane is a material temporary storage bin. If the material bin is full of materials, it is necessary to start the crane to move the material bin to the unloading area. At this time, the material suction and taking work will be suspended, resulting in a break point in the material discharging. During the suspension period, impurities will enter the materials, affecting the quality of the materials, and at the same time, it will also cause material overflow, thus affecting the environment.

[0005] Furthermore, the existing material suction pipe on the crane has no cleaning device, and the materials will agglomerate in the furnace. It is necessary to manually assist in dispersing the agglomerated materials to completely suck the materials clean; in addition, when the material suction pipe is inserted into the materials to suck the materials, the material suction pipe may be buried by the materials and cannot suck the materials normally; and the equipment has no large-particle filtering device, and the large particles will wear the pipeline, impact the cloth bag on the ash bin, resulting in a shortened service life of the cloth bag, and jamming the blower, causing the equipment to malfunction, etc. Summary of the Invention

[0006] The purpose of the present invention is to provide a material suction crane and a graphitization production system that can cool the materials in the material bin.

[0007] The technical solution of the present invention is as follows: A material suction crane, comprising a trolley and a car body arranged on the trolley and capable of displacing along the X direction. It is characterized in that it further comprises a material cooler, a catcher, a material suction pipe and a conveying pipe. The material cooler is arranged on the trolley. One end of the catcher is a second feed inlet, and the other end is a discharge outlet. The material suction pipe is vertically installed on the trolley. The upper end of the material suction pipe is connected to the second feed inlet through a first pipe. The lower end of the material suction pipe forms a material suction head. The discharge outlet is connected to the material cooler through a second pipe. One end of the conveying pipe is connected to the material cooler.

[0008] Preferably, a filter screen is arranged in the catcher, and the filter screen is arranged between the discharge outlet and the second feed inlet.

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

[0010] Preferably, a third bin is further arranged on the trolley. The discharge cylinder is located above the third bin, and a third pipe is connected to the bottom of the third bin.

[0011] Preferably, the material suction pipe comprises 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 telescopically sleeves the telescopic inner pipe, and the material suction head is arranged at the lower end of the telescopic inner pipe.

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

[0013] Preferably, a C-shaped wall is connected to the outer wall of the material suction head. An air passage is formed between the C-shaped wall and the material suction head. An air inlet is arranged at the upper end of the C-shaped wall, and an air supplement port is formed through the bottom of the C-shaped wall. The air inlet, the air passage and the air supplement port are communicated with each other.

[0014] Preferably, the conveying pipe comprises a second hose, a fourth pipe, a first hose and a fifth pipe connected in sequence. The end of the second hose far from the fourth pipe is connected to the material cooler.

[0015] The present invention also provides a graphitization production system, comprising a graphitization furnace, a frame body arranged outside the graphitization furnace and extending along the Y direction, a first bin arranged beside the graphitization furnace, a fan and the above-mentioned material suction crane. The trolley of the material suction crane slides on the frame body. The material suction head is adapted to the graphitization furnace. The end of the conveying pipe far from the material cooler is connected to the first bin. The fan is connected to the first bin through a sixth pipe.

[0016] Preferably, a second bin is further provided beside the graphitization furnace, and the catcher is communicated with the second bin.

[0017] Compared with the related art, the beneficial effects of the present invention are as follows:

[0018] First, a material cooler is added to the material suction crane, which can quickly cool the sucked material, reduce material oxidation, and ensure material quality;

[0019] Second, the bin is no longer integrated on the material suction crane, so that the unloading after the bin is full no longer occupies the crane, making the entire material taking process without breakpoints, avoiding the mixing of pollutants into the material, and avoiding material overflow, better ensuring material quality and workshop environment, and improving production efficiency; reducing the equipment weight and lowering the plant cost;

[0020] Third, an air inlet and a supplementary air inlet 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 supplementary air inlet for air supplement to ensure the normal operation of the suction work;

[0021] Fourth, a new bin cleaning device (such as a blowing pipe, etc.) is added. During the normal suction process, it can clean the adhesive material on the bottom and side walls of the bin in the graphitization furnace, clean the bin while discharging the material, combine the process flow, and shorten the process time;

[0022] Fifth, a foreign object catcher is newly added at the front end of the material suction crane, which can capture large particle materials, impurities and other foreign objects in the material, avoid the influence of foreign objects on subsequent equipment such as pipelines, cloth bags and air lock fans, improve the service life and reliability of the equipment, and reduce the working pressure of the backend equipment.

[0028] The present invention will be described in detail below with reference to the attached drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same direction as the upper, lower, left, and right directions of the attached drawings themselves, and do not limit the structure.

[0029] As Figure 1 shown, a material suction overhead crane 1 provided in this embodiment includes a large vehicle 13, a small vehicle 15, a material cooler 18, a trapper 19, a material suction pipe 30, a delivery pipe 3, and a third bin 29.

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

[0031] The bottom of the small vehicle 15 is provided with second walking wheels 14 around. The second walking wheels 14 are adapted to the second track 8. A material cooler 18, a third bin 29, and a material suction pipe 30 are installed on the small vehicle 15. The material suction pipe 30 includes a fixed outer pipe 16 and a telescopic inner pipe 12 that are both rectangular. The fixed outer pipe 16 is vertically installed on the small vehicle 15, and the upper end of the fixed outer pipe 16 is connected to the first pipeline 31. The lower end of the fixed outer pipe 16 telescopically sleeved the telescopic inner pipe 12. The lower end of the telescopic inner pipe 12 is provided with a material suction head 17. Since the equipment can realize the movement of the material suction pipe 30 along the length and width directions of the graphitization furnace, and the telescopic inner pipe 12 can realize up and down telescoping, therefore, the material suction head 17 can perform three-dimensional movement to realize the suction of all materials in the furnace.

[0032] As Figure 2As shown, a plurality of air blowing pipes 20 are arranged on the outer periphery of the material suction head 17, and the plurality of air blowing pipes 20 extend along the axial direction of the material 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 installed with a duckbill nozzle, a rotary nozzle or a Laval nozzle. When there is adhesive material on the bottom and side walls of the graphitization furnace, start the compressed air compressor, blow the compressed air out from the air blowing pipe 20, disperse the adhesive material, which is beneficial for the material suction head 17 to suck materials and avoid manual secondary cleaning.

[0033] A C-shaped wall 35 is connected to the outer wall of the material suction head 17. An air passage is formed between the C-shaped wall 35 and the material suction head 17. An air inlet 21 is arranged at the upper end of the C-shaped wall 35, and an air supplement port 22 is formed through the bottom of the C-shaped wall 35. The air inlet 21, the air passage and the air supplement port 22 are communicated with each other.

[0034] The bottom of the material suction head 17 is opened to form a first feed port 23. If the material collapses during the material suction process and buries the first feed port 23 and makes it impossible to suck materials, air enters from the air inlet 21 and flows out from the air supplement port 22 to supplement air and resume the material suction head 17 to continue sucking materials.

[0035] As Figure 3 As shown, one end of the catcher 19 is a second feed port 24, and the second feed port 24 is connected to the fixed outer pipe 16 through a first pipe 31. The other end of the catcher 19 is a discharge port 26, and the discharge port 26 is connected to the inlet of the material cooler 18 through a second pipe 32. A filter screen 25 is arranged in the catcher 19, and the side of the filter screen 25 facing the second feed port 24 is inclined. The filter screen 25 is arranged between the discharge port 26 and the second feed port 24. A discharge cylinder 28 is arranged at the lower end of the catcher 19, and the discharge cylinder 28 is located above the third material bin 29. The discharge cylinder 28 is located between the filter screen 25 and the second feed port 24. Two valves 27 are arranged on the discharge cylinder 28. The lower part of the third material bin 29 is connected with a third pipe 36 for connecting with the second material bin 6.

[0036] The sucked materials enter the catcher 19 through the second feed port 24. When passing through the filter screen 25, the large-particle materials are intercepted by the filter screen 25 and enter the discharge cylinder 28. The finished product materials enter the material cooler 18 for rapid cooling through the filter screen 25 due to their small particle size, avoiding oxidation. The two valves 27 on the discharge cylinder 28 are alternately opened and closed, which can reduce the pressure loss of the third pipe 36 and ensure the smooth falling of the large-particle materials. The materials cooled in the material cooler 18 enter the conveying pipe 3.

[0037] As Figure 4As shown in the figure, the present invention further provides a graphitization production system, including a graphitization furnace 2, a frame 37 arranged outside the graphitization furnace 2 and extending along the Y direction, a first bin 5 arranged beside the graphitization furnace 2, a blower 4, a second bin 6 and the above-mentioned material suction crane 1.

[0038] A first track 7 is provided on the upper surface of the frame 37. The first traveling wheels 11 on the crane 13 are adapted to the first track 7. The third pipe 36 is connected to the second bin 6 through a hose (not shown).

[0039] The conveying pipe 3 includes a second hose 10, a fourth pipe 33, a first hose 9 and a fifth pipe 34 connected in sequence. One end of the second hose 10 away from the fourth pipe 33 is connected to the material cooler 18. One end of the fifth pipe 34 away from the first hose 9 is connected to the first bin 5. The blower 4 is connected to the first bin 5 through a sixth pipe 38. The product material enters the first bin 5 from the conveying pipe 3 to complete the tapping work.

[0040] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
