DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, a dust-absorbing and environment-friendly fine powder conveyor of the present invention comprises a conveying component 1 , a screening component 2 is arranged inside the conveying component 1 , and a recovery component 3 is arranged on one side of the conveying component 1 .

[0035] like Figure 3As shown, the conveying assembly 1 includes a frame 101, a main vibration spring 104 is arranged on the surface of the frame 101, a groove body 103 is arranged at one end of the main vibration spring 104 away from the frame 101, a plurality of guide connecting rods 102 are arranged on both sides of the frame 101, one end of the guide connecting rod 102 is connected to the frame 101, and the end of the guide connecting rod 102 away from the frame 101 is connected to the groove body 103, a vibration isolation spring 105 is arranged below the frame 101, a base frame 106 is arranged at one end of the vibration isolation spring 105 away from the frame 101, and an exciter 107 is installed at one end of the frame 101, there are multiple main vibration springs 104, and the multiple main vibration springs 104 are linearly arranged between the frame 101 and the groove body 103, there are multiple vibration isolation springs 105, and the multiple vibration isolation springs 105 are arranged at intervals at the bottom of the frame 101.

[0036] A sealing cover 108 is provided at one end of the trough body 103 away from the main vibration spring 104 , a feed rack 109 is provided above the trough body 103 , and the feed rack 109 is provided at one end of the trough body 103 close to the vibrator 107 , and a feed hopper 110 is provided above the feed rack 109 .

[0037] When in use, the petroleum coke material is transported to the interior of the trough body 103 through the feed hopper 110. Since the vibrator 107 can generate high-frequency vibrations, during this process, the trough body 103 is continuously vibrated by arranging the vibration isolation spring 105 and the main vibration spring 104, and has stability and reliability during vibration. The vibration is transmitted to the trough body 103 through the cooperation of the main vibration spring 104 and the guide connecting rod 102, so that the petroleum coke material in the trough body 103 slides or is thrown in a direction away from the feed hopper 110, thereby achieving the purpose of linearly conveying the petroleum coke material. However, since smaller material particles or dust will escape from the petroleum coke material during the vibration transportation process, thereby polluting the working environment, the trough body 103 is sealed by the sealing cover 108.

[0038] The inventors found that when transporting petroleum coke raw materials, smaller material particles and dust will float inside the trough body 103, and some will overflow from the feed hopper 110 to cause dust pollution; and under the action of vibration, the dust or impurities attached to the surface of the petroleum coke material will fall off, and then re-attach to the surface of the petroleum coke material, making it inconvenient to screen and separate, affecting the quality of subsequent processing of the petroleum coke material; and the petroleum coke material will agglomerate due to long-term storage, which increases the difficulty of screening and separation and affects transportation efficiency. In addition, excessive pressure on the trough body 103 during transportation will cause deformation or wear, affecting its service life.

[0042] like Figure 7 As shown, the screening assembly 2 includes a fixed sieve plate 201, a feed hopper 110 is located above the fixed sieve plate 201, one end of the fixed sieve plate 201 is connected to the inner wall of the trough body 103, a movable sieve plate 202 is provided at the end of the fixed sieve plate 201 away from the trough body 103, hydraulic rods 203 are provided on both sides of the movable sieve plate 202, limiting plates 205 are provided on both sides of the movable sieve plate 202, and a rack 204 is provided below the movable sieve plate 202.

[0043] A limiting groove is provided at the position where the limiting plate 205 is connected to the movable screen plate 202 . The end of the limiting plate 205 away from the movable screen plate 202 is connected to the inner wall of the tank body 103 . The end of the hydraulic rod 203 away from the movable screen plate 202 is connected to the inner wall of the tank body 103 .

[0044] like Figure 8 As shown, a slot is provided at the position where the fixed sieve plate 201 and the movable sieve plate 202 are connected, and a protrusion 2021 is provided on one side of the movable sieve plate 202 close to the slot. There are multiple protrusions 2021, and multiple protrusions 2021 are arranged on the movable sieve plate 202 at intervals.

[0045] like Figure 5 As shown, a rotating frame 206 is arranged on the surface of the limiting plate 205, a rotating groove is opened at the position where the limiting plate 205 and the rotating frame 206 are connected, a crushing roller 207 is arranged at the end of the rotating frame 206 away from the limiting plate 205, a plurality of crushing teeth 2071 are arranged on the surface of the crushing roller 207, a connecting rod 208 is hingedly arranged on one side of the rotating frame 206, and a sliding seat 209 is hingedly arranged on the end of the connecting rod 208 away from the rotating frame 206.

[0046] A movable groove is provided on the surface of the limiting plate 205, and the sliding seat 209 is arranged inside the movable groove. A return spring 210 is provided at the end of the sliding seat 209 away from the movable screen plate 202, and the end of the return spring 210 away from the sliding seat 209 is connected to the limiting plate 205. A clamping column 211 is provided at the end of the movable screen plate 202 close to the sliding seat 209, and a clamping groove matched with the clamping column 211 is provided on the surface of the sliding seat 209.

[0047] During use, since smaller material particles and dust will float inside the tank 103, some will overflow from the feed hopper 110 to cause dust pollution, and the dust or impurities attached to the surface of the petroleum coke material will fall off under the action of vibration, and then re-attach to the surface of the petroleum coke material, making it difficult to separate. At this time, the screening component 2 and the recovery component 3 cooperate to screen and collect the petroleum coke material, specifically:

[0048] First, the petroleum coke material enters from the feed hopper 110 and falls on the fixed sieve plate 201. Under the action of vibration, smaller material particles or dust in the petroleum coke material pass through the fixed sieve plate 201 and fall to the bottom of the fixed sieve plate 201, and larger material particles remain on the fixed sieve plate 201 and move along the fixed sieve plate 201, and finally fall and slide or throw along the trough body 103 in the direction away from the feed hopper 110, thereby achieving the purpose of linear transportation of the petroleum coke material. At the same time, under the action of the fan of the cyclone separator 303, smaller material particles or dust screened out in the trough body 103 pass through the dust suction frame 301 and are transported to the cyclone separator 303 along the suction pipe 302, and solid-gas separation is performed under the action of the cyclone separator 303, wherein the smaller material particles and dust mixture are discharged from the discharge pipe 304. At this time, the gas separated in the cyclone separator 303 enters the bag dust collector through the exhaust pipe 305 for further filtration and discharge.

[0049] However, it was found in the above process that the petroleum coke material could not be effectively screened by fixing the screen plate 201, resulting in some dust adhering to the surface of the petroleum coke material and being transported out, and the petroleum coke material would agglomerate due to long-term storage, which aggravated the difficulty of screening and separation. At this time, a visual sensor was provided at the end of the trough body 103 away from the feed hopper 110, that is, the petroleum coke material at the discharge end of the trough body 103 was detected by the visual sensor, and the transportation status of the petroleum coke material was judged according to the detection result.

[0050] If the visual sensor detects that the particle size of the petroleum coke material at the discharge end of the trough body 103 is small and the content is high, it means that the fixed sieve plate 201 cannot effectively screen the petroleum coke material, resulting in part of the dust adhering to the surface of the petroleum coke material and being transported out. At this time, the controller controls the hydraulic rod 203 to extend according to the detection result of the visual sensor, and the hydraulic rod 203 pushes the movable sieve plate 202 to move in the direction away from the fixed sieve plate 201, and the movable sieve plate 202 extends from the slot in the fixed sieve plate 201, thereby increasing the screening displacement and screening time of the material, and improving the screening degree of the petroleum coke material, that is, the petroleum coke material is screened by the fixed sieve plate 201 and the movable sieve plate 202 in turn, and the smaller petroleum coke material particles or dust fall from the fixed sieve plate 201 and the movable sieve plate 202, and the larger petroleum coke material after screening falls from one end of the movable sieve plate 202 onto the trough body 103, and slides or is thrown along the trough body 103 in the direction away from the feed hopper 110.

[0051] At the same time, when the hydraulic rod 203 pushes the movable sieve plate 202 to move away from the fixed sieve plate 201, the movable sieve plate 202 drives the rack 204 to move together. Under the joint action of the rack 204 and the gear 309, the gear 309 drives the rotating shaft 307 to rotate together, so that the guide frame 306 deflects toward the fixed sieve plate 201 with the rotating shaft 307 as the rotation center, changes the flow direction of part of the gas, increases the gas flow rate near the fixed sieve plate 201 and the movable sieve plate 202, increases the suction force on smaller petroleum coke material particles or dust, and collects and cleans the fallen smaller petroleum coke material particles or dust in time to avoid dust or impurities re-attaching to the surface of the petroleum coke material, resulting in poor cleaning effect.

[0052] It is worth noting that in the above process, since the crushing roller 207 is located above the fixed screen plate 201, the crushing teeth 2071 on the crushing roller 207 are not in contact with the surface of the fixed screen plate 201 at this time. During screening, the multiple crushing teeth 2071 on the surface of the crushing roller 207 move the petroleum coke material at different positions on the fixed screen plate 201, thereby evenly diverting the petroleum coke material on the fixed screen plate 201 below the crushing roller 207 to avoid uneven screening caused by the accumulation of petroleum coke materials. At the same time, it is also convenient to evenly collect the smaller petroleum coke material particles or dust that have fallen, to avoid excessive local amounts affecting the collection and cleaning effect, so that the subsequent petroleum coke materials are evenly transported on the trough body 103, thereby improving the uniformity of transportation.

[0053] In addition, during the screening and separation process, if the petroleum coke material agglomerates in a large volume and moves slowly, causing blockage, or if the height of the petroleum coke material agglomerates in the vertical direction exceeds the height of the position of the crushing roller 207, it will also cause blockage, that is, the petroleum coke material is blocked by the crushing roller 207 and cannot pass through, affecting the transportation efficiency and the screening and separation effect. At this time, under the action of vibration, the petroleum coke material will collide and squeeze the crushing roller 207. At this time, under the action of force transmission, the return spring 210 is compressed. At this time, the supporting force of the connecting rod 208 on it decreases, and the sliding seat 209 squeezes the return spring 210 to cause it to deform. The blockage situation at this time can be obtained by detecting the deformation amount of the return spring 210. That is, a pressure sensor is provided inside the sliding seat 209. The deformation amount of the return spring 210 can be calculated through the detection value of the pressure sensor, and then the blockage situation at this time can be obtained.

[0054] If the detection value of the pressure sensor exceeds the preset value, it indicates that the petroleum coke material is blocked due to the large volume of the agglomerates. At this time, the controller controls the hydraulic rod 203 to reciprocate, and the hydraulic rod 203 drives the movable screen plate 202, the clamping column 211 and the sliding seat 209 to reciprocate together. Under the joint action of the sliding seat 209, the connecting rod 208 and the rotating frame 206, the position of the crushing roller 207 is changed, so that the crushing roller 207 and the crushing teeth 2071 squeeze and crush the petroleum coke material, thereby reducing its volume and achieving the purpose of breaking up the agglomerated petroleum coke material. At the same time, the reciprocating motion of the movable screen plate 202 can accelerate the screening and separation speed of the petroleum coke material, specifically:

[0055] The controller controls the hydraulic rod 203 to continue to extend, and the hydraulic rod 203 pushes the movable sieve plate 202 to move in the direction away from the fixed sieve plate 201. At this time, the movable sieve plate 202 drives the clamping column 211 to move in the direction close to the sliding seat 209. Under the action of the movable sieve plate 202, the clamping column 211 enters the interior of the clamping slot on the sliding seat 209 and squeezes the sliding seat 209. The reset spring 210 is compressed, so that the clamping column 211 and the clamping slot are limited and locked.

[0056] At the same time, the sliding seat 209 drives the connecting rod 208 to move together, and the rotating frame 206 drives the crushing roller 207 to deflect in the direction close to the fixed screen plate 201, so that the crushing roller 207 drives the crushing teeth 2071 to squeeze and crush the petroleum coke material on the fixed screen plate 201 into small pieces. In this process, the crushing teeth 2071 on the crushing roller 207 collide with the petroleum coke material on the fixed screen plate 201 to generate vibration, thereby accelerating the falling of smaller petroleum coke material particles or dust on the fixed screen plate 201. At the same time, the dust adhering to the surface of the fixed screen plate 201 can also be cleaned, thereby improving the screening and separation degree of the petroleum coke material at this position.

[0057] Then the controller controls the hydraulic rod 203 to contract, and the hydraulic rod 203 drives the movable screen plate 202, the clamping column 211, and the sliding seat 209 to move together in the direction close to the fixed screen plate 201. At this time, the reset spring 210 is stretched. In this process, the sliding seat 209 drives the connecting rod 208 to move together. Under the joint action of the sliding seat 209 and the connecting rod 208, the rotating frame 206 drives the crushing roller 207 to deflect in the direction away from the fixed screen plate 201, so that the crushing roller 207 drives the crushing teeth 2071 to squeeze and crush the petroleum coke material on the fixed screen plate 201 into small pieces. Since the movement direction of the petroleum coke material on the fixed screen plate 201 is opposite to the movement displacement direction of the crushing roller 207 in the horizontal direction, the impact force of the crushing roller 207 and the crushing teeth 2071 on the petroleum coke material at this position is increased. At the same time, the petroleum coke material at this position can also be rolled and pulled to break it into small pieces, thereby improving the degree of crushing.

[0058] At the same time, the cooperation between the crushing roller 207 and the crushing teeth 2071 can also push the petroleum coke material on the fixed screen plate 201 in the opposite direction, so as to prevent the insufficiently crushed petroleum coke material from moving to the movable screen plate 202 and affecting the subsequent screening process and the uniformity of conveying the petroleum coke material. In addition, the multiple crushing teeth 2071 on the surface of the crushing roller 207 can move the petroleum coke material at different positions on the fixed screen plate 201 to make it evenly distributed, so as to avoid unevenness or excessive accumulation of the petroleum coke material, which may easily cause blockage.

[0059] In addition, when the hydraulic rod 203 drives the movable screen plate 202 to move in the direction close to the fixed screen plate 201, that is, the movable screen plate 202 shrinks into the slot in the fixed screen plate 201, during this process, the slot can clean the petroleum coke material particles adhering to the movable screen plate 202 or the petroleum coke material stuck in the sieve holes of the movable screen plate 202, thereby ensuring the normal screening of the petroleum coke material. At the same time, the protrusion 2021 on the movable screen plate 202 collides with the inner wall of the slot of the fixed screen plate 201 to vibrate the movable screen plate 202, thereby improving the screening efficiency of the movable screen plate 202 for the petroleum coke material, and accelerating the falling off of the petroleum coke material particles adhering to the movable screen plate 202, thereby improving the cleaning effect.

[0060] It is worth noting that an arc-shaped groove matched with the protrusion 2021 is formed on the inner wall of the slot, and the arc-shaped groove corresponds to the protrusion 2021 one by one. In the above process, when the controller controls the hydraulic rod 203 to drive the movable screen plate 202 to reciprocate, the protrusion 2021 will not interfere with the movement of the movable screen plate 202. When the protrusion 2021 on the movable screen plate 202 is misaligned with the arc-shaped groove of the slot on the fixed screen plate 201, the protrusion 2021 collides with the inner wall of the slot of the fixed screen plate 201, so that both the fixed screen plate 201 and the movable screen plate 202 produce secondary vibrations, thereby increasing the vibration amplitude. At this time, under the action of the secondary vibration, the screening rate and screening effect of the petroleum coke material can be improved. At the same time, the petroleum coke material adhered to the fixed screen plate 201 and the movable screen plate 202 can be automatically cleaned to avoid clogging of the petroleum coke material and affecting the normal screening work.

[0061] In the above process, when the hydraulic rod 203 is controlled by the controller to drive the movable screen plate 202 to move back and forth, the petroleum coke material on the movable screen plate 202 will be thrown up and then fall back, and at the same time, the reciprocating vibration of the movable screen plate 202 helps to stratify and screen the petroleum coke material, and the process of throwing up and falling back helps to crush, mix and further screen the petroleum coke material, thereby accelerating the falling of smaller petroleum coke material particles or dust on the movable screen plate 202.

[0062] At the same time, when the controller controls the hydraulic rod 203 to drive the movable screen plate 202 to reciprocate, the crushing roller 207 and the crushing teeth 2071 will also squeeze and crush the petroleum coke material at different positions, thereby reducing its volume and achieving the effect of breaking up the agglomerated petroleum coke material. At the same time, it is not only convenient for screening the petroleum coke material, but also can reduce the pressure on the trough body 103 during transportation, thereby avoiding deformation or wear of the trough body 103, thereby affecting the service life.

[0063] It is worth noting that by accelerating the reciprocating speed of the movable screen plate 202 and increasing the vibration intensity, the screening efficiency of the petroleum coke material can be improved. In addition, the strength of the crushing roller 207 and the crushing teeth 2071 in squeezing and crushing the petroleum coke material can be increased to avoid blockage caused by unevenness or excessive accumulation of the petroleum coke material.
