Description

Technical Field

[0001] The invention relates to the technical field of graphite roasting and discharging, in particular to a discharging device for a roasting steel drum for isostatically pressed graphite. Background Art

[0002] Isostatically pressed graphite is commonly used in metallurgy, chemical industry, aerospace, machinery, nuclear energy and other technical fields. In the preparation process of isostatically pressed graphite, graphite particles are usually placed in a roasting barrel in advance, and then the roasting work is carried out. Among them, the uniform placement of graphite particles in the roasting barrel is related to the quality of the roasted graphite. The current green body loading process mainly involves placing the bottom layer of sand - scraping - placing the product - placing the middle layer of material - scraping - placing the upper layer of product - placing the upper layer of sand - scraping. The process involves at least three steps of scraping. Whether the scraping process is done manually or by equipment, it is time-consuming and labor-intensive, and different scraping devices need to be designed according to different barrel types.

[0003] Chinese patent CN 214872927 U discloses an isostatically pressed graphite product production device, which belongs to the technical field of graphite processing equipment. The isostatically pressed graphite product production device includes a base plate, a cold isostatic press body fixedly mounted on the upper surface of the base plate, and a working cylinder body slidably connected to the upper surface of the base plate. A placement plate is fixedly connected to the upper surface of the base plate near the working cylinder body, and at least two support plates are slidably connected to the upper surface of the placement plate. The upper surface of the support plate is fixedly connected to a placement groove, and a material barrel is clamped to the inner side wall of the placement groove.

[0004] However, this technical solution has the following defects:

[0005] 1. This solution uses manual scraping, which results in uneven scraping, poor working environment, and is time-consuming and labor-intensive.

[0006] 2. This solution cannot switch to different scraping ranges according to barrels of different sizes, and its scope of application is small. Summary of the Invention

[0007] The purpose of the present invention is to address the shortcomings of the existing technology and provide a discharging device for roasting steel drums for isostatically pressed graphite. By adopting an automatic lifting method along the inner wall of the steel drum, the discharging and scraping are carried out synchronously, the working efficiency is high, and the steps of multiple manual discharging and scraping are eliminated. Each time the steel drum is switched, the steel drum can be automatically positioned to ensure that the central axis of the steel drum and the central axis of the discharging and scraping assembly are on the same vertical line, so that the discharging assembly and the scraping assembly can simultaneously reach the inner wall of the steel drum when extending in the steel drum, thereby achieving the range of automatically adjusting the discharging and scraping according to the size of the drum.

[0066] An exhaust mechanism for exhausting air is provided on the side of the second lifting assembly.

[0067] The beneficial effects of the present invention are:

[0068] (1) When the first push rod is driven to the end point of the reciprocating screw by the first reciprocating screw, the first driving shaft stops rotating. At this time, the first clamping plate is pushed along the first push rod to contact the outer side of the steel barrel, and then the first fastener is rotated to fix the first clamping plate, thereby achieving the effect of positioning different barrel sizes.

[0069] (2) The present invention drives the steel barrel to be fed in a rhythmic manner through the first driving mechanism. When the steel barrel is clamped by the first clamping plate, the first push rod is also located at the end point of the first reciprocating screw. After the steel barrel is filled, the first driving mechanism drives the first reciprocating screw to rotate further through the first driving shaft. The first push rod drives the first clamping plate to separate from the outside of the steel barrel and the conveyor belt sends the filled steel barrel to the next station through the push plate. Thus, each time the steel barrel is switched, the steel barrel can be automatically positioned to ensure that the central axis of the steel barrel and the central axis of the discharge and scraping assembly are on the same vertical line, so that the discharge assembly and the scraping assembly can simultaneously reach the inner wall of the steel barrel when extending in the steel barrel.

[0070] (3) The present invention drives the rack rack to move along the sleeve frame through the driving wheel, so that the first ball hits the inner wall of the steel barrel, the driving wheel stops rotating, and the rack rack drives the discharge plate to move outward along the third guide plate through the fixed plate. During this process, the third driving mechanism on one side of the discharge plate moves along the third guide groove through the slider, so that the range of the discharge port at the bottom of the discharge plate is equal to the radius inside the steel barrel, thereby achieving the ability to automatically adjust the discharge range according to the size of the barrel.

[0071] (4) The present invention drives the rack rack to move along the sleeve frame through the driving wheel, so that the first ball hits the inner wall of the steel barrel, the driving wheel stops rotating, and the rack rack drives the discharge plate to move outward along the third guide plate through the fixed plate. During this process, the third driving mechanism on one side of the discharge plate moves along the third guide groove through the slider, so that the distribution range of the discharge port at the bottom of the discharge plate is equal to the radius inside the steel barrel, thereby achieving the ability to automatically adjust the discharge range according to the size of the barrel.

[0072] (5) The present invention drives the driven wheel to rotate through the first driving rack, and the driven wheel moves along the fourth guide plate through the scraper extension mechanism. The scraper extension mechanism drives the movable scraper plate to move in the opposite direction of the discharge plate until the second ball contacts the inner wall of the steel drum, and the movable scraper plate stops moving. During the movement of the movable scraper plate, the fixed scraper plate remains stationary, so that in the subsequent rotary scraping process, the fixed scraper plate always performs the scraping work, and the movable scraper plate extends according to the size of the steel drum and only the part that does not overlap with the fixed scraper plate performs the scraping work, thereby achieving the effect of being able to automatically adjust the scraping range according to the size of the steel drum.

[0073] (6) The present invention arranges the fixed scraper plate and the movable scraper plate at an angle, so that the graphite material that falls excessively at the center of the steel drum can be diffused toward the edge of the steel drum along the fixed scraper plate and the movable scraper plate arranged in an inclined trajectory, thereby achieving a more uniform discharge effect.

[0074] (7) The present invention generates an upward force on the first jack through the cantilever beam, so that the cantilever beam pushes the lifting frame to move gradually upward along the lifting groove through the first jacking component, so that the discharge unit can automatically lift upward along the inner wall of the steel drum every time it rotates one circle to perform the discharge work, thereby achieving the effect of automatically lifting along the inner wall of the steel drum, coordinating the discharge and scraping simultaneously, high work efficiency, and eliminating the need for multiple manual discharge and scraping.

[0075] In summary, the present invention has the advantages of flexible and controllable material discharge, adjustable material discharge speed and range, reduced manual operation, guaranteed personnel operation safety and working environment, omitted repeated manual scraping steps, reduced operation time, and improved work efficiency.

[0152] The lower end of the fourth guide plate 221 is open.

[0153] It should be noted that if Figure 1-3 As shown, the steel drum is placed on the upper part of the conveyor belt 112, and the first driving mechanism 122 is started. The first driving mechanism 122 drives the push shaft 110 to rotate through the chain 111, and the push shaft 110 drives the push plate 1121 through the conveyor belt 112 to push the steel drum to move between the first clamping plate 1241 and the second clamping plate 1261. While the first driving mechanism 122 drives the chain 111 to rotate, the first driving mechanism 122 drives the first driving shaft 123 to rotate, and the first driving shaft 123 drives the first push rod 123 through the first reciprocating screw 1231. 4 moves toward the steel drum, and the first push rod 124 presses against the outer side of the steel drum through the first clamping plate 1241. Similarly, the first driving shaft 123 pushes the second clamping plate 1261 to the outer side of the steel drum through the second push rod 126, so that the upper end opening of the steel drum is positioned directly below the discharge unit 2. This facilitates the subsequent insertion of the discharge unit 2 into the steel drum, ensuring that the axis of the second driving shaft 210 and the central axis of the steel drum are on the same vertical line, so that the initial distances between the discharge assembly 21 and the inner wall of the steel drum are equal.

[0154] The present invention is initially adjusted, such as Figure 2-3As shown, first loosen the first fastener 1242 and the second fastener 1262, place the barrel on the upper part of the conveyor belt 112 and between the first clamping plate 1241 and the second clamping plate 1261, rotate the first drive shaft 123, and when the first drive shaft 123 drives the first push rod 124 to the end point of the reciprocating screw 1231 through the first reciprocating screw 1231, stop rotating the first drive shaft 123. At this time, push the first clamping plate 1241 along the first push rod 124 to contact the outside of the steel barrel, and then rotate the first fastener 1242 to fix the first clamping plate 1241. The adjustment principle of the second clamping plate 1261 is the same as that of the first clamping plate 1241, which will not be repeated here, thereby achieving the effect of positioning different barrel sizes.

[0155] During operation, the first driving mechanism 122 drives the steel barrel to feed according to the beat. When the steel barrel is clamped by the first clamping plate 1241, the first push rod 124 is also located at the end point of the first reciprocating screw 1231. After the steel barrel is filled, the first driving mechanism 122 drives the first reciprocating screw 1231 to rotate further through the first driving shaft 123. The first push rod 124 drives the first clamping plate 1241 to separate from the outside of the steel barrel and the conveyor belt 112 sends the filled steel barrel to the next workstation through the push plate 1121, thereby realizing that each time the steel barrel is switched, the steel barrel can be automatically positioned to ensure that the center axis of the steel barrel and the center axis of the discharge and scraper assembly 22 are on the same vertical line, so that the discharge assembly 21 and the scraper assembly 22 can simultaneously reach the inner wall of the steel barrel when extending in the steel barrel.

[0156] After the steel drum is positioned, the lifting unit 3 is controlled, and the lifting unit 3 drives the discharge unit 2 to move downward from the top of the steel drum to the bottom of the steel drum. The working process of the lifting unit 3 will be described in detail later. Then, the motor on the side of the driving wheel 213 is started, as shown in FIG. Figure 7-9 As shown, the motor drives the rack 2142 to move along the sleeve frame 2141 through the driving wheel 213, so that the first rolling ball 21421 hits the inner wall of the steel drum, and the driving wheel 213 stops rotating. The rack 2142 drives the discharge plate 2144 to move outward along the third guide plate 2147 through the fixed plate 2143. During this process, the third driving mechanism 21444 on one side of the discharge plate 2144 moves along the third guide groove 21471 through the slider 21441, so that the range of the discharge port distribution at the bottom of the discharge plate 2144 is equal to the radius inside the steel drum, thereby achieving the goal of automatically adjusting the discharge range according to the size of the drum.

[0157] While the unloading plate 2144 is moving, Figure 5 、 Figure 8 、 Figure 10As shown, the discharge plate 2144 drives the driven wheel 2213 to rotate through the first driving rack 2146, and the driven wheel 2213 moves along the fourth guide plate 221 through the scraper extension mechanism 222, and the scraper extension mechanism 222 drives the movable scraper plate 2221 to move in the opposite direction of the discharge plate 2144 until the second ball 223 contacts the inner wall of the steel drum, and the movable scraper plate 2221 stops moving. During the movement of the movable scraper plate 2221, the fixed scraper plate 224 remains stationary, so that in the subsequent rotating scraping process, the fixed scraper plate 224 always performs the scraping work, and the movable scraper plate 2221 extends according to the size of the steel drum and only the part that does not overlap with the fixed scraper plate 224 performs the scraping work, thereby achieving the effect of automatically adjusting the scraping range according to the size of the steel drum;

[0158] After the discharge unit 2 finishes extending in the steel barrel, the graphite material is placed in the material holding frame 302 , and the graphite material falls into the transfer bucket 2103 along the material holding frame 302 , and then enters the discharge plate 2144 through the discharge pipe 212 and the receiving hopper 21422 in sequence and is located on the side of the pre-baffle 21442 .

[0167] Furthermore, the first lifting assembly 305 includes:

[0168] Fine adjustment mechanism 3051;

[0169] A first cavity 30521 connected to one side of the fine-tuning mechanism 3051;

[0170] A first top column 30522 is slidably inserted into the first cavity 30521;

[0171] A second return spring 30523 is sleeved outside the first top column 30522 and inside the first cavity 30521;

[0172] The fine-tuning mechanism 3051 includes:

[0173] Sleeve 30511;

[0174] A push block 30513 is slidably inserted into the sleeve 30511;

[0175] The push block 30513 is located inside the sleeve 30511 and is provided with a piston;

[0176] An air inlet pipe 30512 is provided inside the sleeve 30511 and located above the push block 30513;

[0177] A first return spring 30514 is slidably connected to the side of the push block 30513 and located inside the sleeve 30511;

[0178] The first return spring 30514 is connected to the limiting block 30515;

[0179] The side of the sleeve 30511 and located inside the first lifting assembly 305 is connected to a gas control valve 30516 for collecting the gas pushed by the push block 30513 into the first cavity 30521 through the first conduit 30519;

[0180] A first baffle 30517 is inserted into the air control valve 30516;

[0181] A first elastic block 30518 is inserted into one side of the first baffle 30517 .

[0182] Furthermore, the side of the first conduit 30519 is connected to a second conduit 30524 which is connected to the second lifting assembly 306;

[0183] A second cavity 3061 is provided in the second lifting assembly 306. A second lifting column 3062 is inserted into the second cavity 3061. A third return spring 3063 is sleeved on the outside of the second lifting column 3062 and inside the second cavity 3061.

[0184] A third conduit 3064 is provided on the side of the second cavity 3061;

[0185] The side of the second lifting assembly 306 is provided with an exhaust mechanism 3065 for exhausting gas, and the exhaust mechanism 3065 includes:

[0186] A second elastic stopper 30651, wherein a spring is provided inside the second elastic stopper 30651;

[0187] The second elastic block 30651 is connected to a second baffle 30652 near the opening of the third conduit 3064;

[0188] A cylinder 30653 is provided on the outer side of the opening of the third conduit 3064 .

[0189] It should be noted that, when discharging the material, the second driving mechanism 2101 and the third driving mechanism 21444 are started, and the third driving mechanism 21444 drives the spiral feeding mechanism 21443. Figure 8 As shown, the graphite material originally located on one side of the discharge plate 2144 is fed along the inner wall of the discharge plate 2144 and falls into the bottom of the steel drum along the baffle plate 2145 at the opening of the discharge plate 2144. At the same time, the second driving mechanism 2101 drives the discharge assembly 21 and the scraper assembly 22 to rotate synchronously through the second driving shaft 210. After the graphite material discharged by the discharge assembly 21 rotates one circle, it will be scraped by the fixed scraper plate 224 and the movable scraper plate at the bottom of the scraper assembly 22. 2221 scraping, because the discharge plate 2144 in the present invention has the same dropping rate at the bottom, the thickness of the graphite material accumulation at the center of the bottom of the steel drum after dropping is greater than the thickness at the edge. Therefore, the present invention arranges the fixed scraper plate 224 and the movable scraper plate 2221 at an angle, so that the graphite material that falls excessively at the center of the steel drum can be diffused to the edge of the steel drum along the fixed scraper plate 224 and the movable scraper plate 2221 arranged in an inclined trajectory, thereby achieving a more uniform discharge effect;

[0190] Every time the second drive shaft 210 rotates one circle, the protrusion 2102 drives the push block 30513 to move back and forth along the sleeve 30511 once. Figure 11-14As described above, the push block 30513 passes over the air inlet pipe 30512 and compresses the first return spring 30514, so that the air pressure in the sleeve 30511 enters the air control valve 30516 through the first baffle 30517. When the protrusion 2102 separates from the push block 30513, the first elastic block 30518 blocks the first baffle 30517 to prevent the gas in the air control valve 30516 from flowing back. After entering the air control valve 30516, the gas flows along the first conduit 30519 into the first cavity 30521 and pushes the first top column 30522 downward to compress the second return spring 305 23. The first supporting column 30522 is pressed against the cantilever beam 303. At this time, the cantilever beam 303 exerts an upward force on the first supporting column 30522, so that the cantilever beam 303 pushes the lifting frame 304 to gradually move upward along the lifting groove 3011 through the first lifting assembly 305. As a result, the unloading unit 2 can be automatically lifted upward along the inner wall of the steel drum every time it rotates one circle to unload the material. This achieves the effect of automatically lifting along the inner wall of the steel drum, coordinating the unloading and scraping of the material simultaneously, achieving high work efficiency and eliminating the need for multiple manual unloading and scraping operations.

[0191] In order to prevent the first lifting column 30522 from pushing the cantilever beam 303 upward with excessive force on the left side of the second driving mechanism 2101, thereby preventing the cantilever beam 303 from becoming unbalanced, a second conduit 30524 is connected to the side of the first conduit 30519 and leading to the second lifting assembly 306. While the gas enters the first cavity 30521 along the first conduit 30519, it also enters the second cavity 3061 through the second conduit 30524, pushing the second lifting column 3062 to compress the third return spring 3063, pressing it against the cantilever beam 303.

[0192] When the discharge unit 2 moves upward to the inside of the fully thrust steel barrel, the conveyor belt 112 transfers the steel barrel through the push plate 1121, and transfers the next group of empty steel barrels to start the positioning work. Then, the cylinder 30653 is started, and the cylinder 30653 pushes the second elastic block 30651 to disengage from the second baffle 30652, so that the gas in the first lifting component 305 and the second lifting component 306 is released at the second baffle 30652, and the first lifting column 30522 and the second lifting column 3062 are reset, and the discharge unit 2 sinks to the bottom of the steel barrel again to perform the discharge and scraping work.

[0193] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
