Description

Technical Field

[0002] At present, belt conveyors are often used for long-distance transportation of various materials. In order to realize redirection transportation, two belt conveyors need to be connected end to end and a transfer device is used at the joint for transfer and transportation.

[0003] CDQ is a dry powder material, which is often transported by two belt conveyors in combination with a transfer device. However, during the material transfer process, the material will cause a large impact on the transfer device, causing serious wear and tear of the lining or steel plate in the transfer device, which requires frequent replacement. At the same time, CDQ transportation will cause the material to leak easily and raise dust in the air. In order to reduce the dust during the transfer of the two conveyors, most conveyor transfer points use dust collectors for mechanical dust extraction, but this will generate a large dust removal energy consumption, which directly increases the transportation cost of the material.

[0061] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0062] like Figures 1 to 9 As shown, the present application provides a material conveying and transferring device, including an incoming belt conveyor 1, an outgoing belt conveyor 7 and a transfer component, the transfer component including:

[0063] The transfer funnel 2, the discharge end of the incoming belt conveyor 1 extends into the transfer funnel 2;

[0064] A first elastic vibration slide plate 3 is arranged in the transfer hopper 2 and in front of the incoming belt conveyor 1. The plate surface of the first elastic vibration slide plate 3 facing the incoming belt conveyor 1 is a concave guide surface, and the first elastic vibration slide plate 3 can automatically swing elastically under the impact of the material;

[0065] The chute 4 has an upper end connected to the discharge port at the bottom of the transfer funnel 2, and the upper end of the chute 4 is bent and extended toward the discharge end of the discharge belt conveyor 7; the inner wall of one side of the chute 4 forms a guide surface for guiding the material;

[0066] A plurality of second elastic vibration slide plates 5 are arranged on the guide surface of the chute 4 from top to bottom at intervals, and an acute angle is formed between the extension direction from the upper end to the lower end of the second elastic vibration slide plate 5 and the guide surface, and the second elastic vibration slide plate 5 can automatically swing elastically under the impact of the material;

[0067] The material guide trough structure 6 is connected to the lower end of the chute 4 and the feed end of the discharging belt conveyor 7 through the top opening and the bottom notch respectively.

[0068] Among them, the discharging belt conveyor 7 is located below the incoming belt conveyor 1, the first elastic vibration slide plate 3 is located outside the incoming belt conveyor 1, the discharge port of the transfer funnel 2 is preferably arranged corresponding to the gap between the discharging end of the incoming belt conveyor 1 and the first elastic vibration slide plate 3, and the guide trough structure 6 is installed above the feeding end of the discharging belt conveyor 7. When in use, the material is thrown off the discharging end of the incoming belt conveyor 1 and falls along the concave guide surface of the first elastic vibration slide plate 3, enters the chute 4 through the discharge port, and then enters the feeding end of the discharging belt conveyor 7.

[0069] Under the impact of the material, the first elastic vibration slide plate 3 can automatically swing elastically, and can automatically adjust the distance between the discharge end of the incoming belt conveyor 1 and the first elastic vibration slide plate 3, so that the material can be in tangential contact with the concave guide surface and fall along the arc curve of the concave guide surface. The falling speed and direction of the material can be controlled by changing the angle of the arc curve, and the falling position of the material can also be adjusted. Combined with the characteristics of the first elastic vibration slide plate 3 that can automatically swing elastically, it can not only buffer the material and reduce the impact force of the material on the transfer funnel 2 and the conveyor belt of the discharge belt conveyor 7, but also prevent the transfer funnel 2 from being blocked. Under the impact of the material, each second elastic vibration slide plate 5 can automatically swing elastically, which can buffer the material entering the chute 4 step by step. Combined with the characteristics of the second elastic vibration slide plate 5 that can automatically swing elastically, it can also prevent the chute 4 from being blocked.

[0070] Therefore, the material conveying and transferring device in the present application can adjust the material flow rate, directly reduce the material conveying loss, effectively reduce the impact force of the material on the transfer funnel 2, the chute 4 and the conveyor belt of the discharge belt conveyor 7, and improve the service life of the device. It can also effectively prevent the risk of material blockage in the transfer funnel 2 and the chute 4. The swing of each slide can be automatically adjusted under the impact of the material, without manual direct adjustment, saving operating costs. In addition, the transfer funnel 2 and the guide trough structure 6 are respectively connected to the incoming belt conveyor 1 and the discharge belt conveyor 7 to prevent dust generated during material transportation, which is more environmentally friendly.

[0071] In the specific implementation, in order to facilitate the automatic elastic swing of each elastic vibration slide plate, refer to Figure 3The upper part of the first elastic vibration slide plate 3 is hinged to the inner side wall of the transfer funnel 2 through a first hinge shaft 31, and the lower part is hinged with a first guide rod 32. The first guide rod 32 can be automatically elastically telescopically moved and sealed to penetrate the side wall of the transfer funnel 2, so that the first elastic vibration slide plate 3 can automatically swing around the first hinge shaft 31 under the impact of the material; refer to Figure 4 The upper part of the second elastic vibration slide plate 5 is hinged to the guide surface of the chute 4 through a second hinge shaft 51, and the lower part is hinged with a second guide rod 52. The second guide rod 52 can automatically elastically telescopically move and seal through the side wall of the chute 4, so that the second elastic vibration slide plate 5 can automatically swing around the second hinge shaft 51 under the impact of the material.

[0072] Specifically, a first mounting hole is opened on the side wall of the transfer funnel 2, the first end of the first guide rod 32 is hinged to the lower part of the first elastic vibration slide plate 3, and the second end can be axially movable and sealed to pass through the first mounting hole; a first inner limit block 33 and a first outer limit block 34 are respectively provided at the first end and the second end of the first guide rod 32, and a first spring 35 is sleeved on the first guide rod 32, and the two ends of the first spring 35 respectively press against the first inner limit block 33 and the inner wall of the transfer funnel 2, and the first outer limit block 34 can press against the outer wall of the transfer funnel 2.

[0073] A second mounting hole is opened on the side wall of the slide pipe 4, the first end of the second guide rod 52 is hinged to the lower part of the second elastic vibration slide plate 5, and the second end can be axially movable and sealed to pass through the second mounting hole; a second inner limit block 53 and a second outer limit block 54 are respectively provided at the first end and the second end of the second guide rod 52, and a second spring 55 is sleeved on the second guide rod 52, and the two ends of the second spring 55 are respectively pressed against the second inner limit block 53 and the inner side wall of the slide pipe 4, and the second outer limit block 54 can be pressed against the outer side wall of the slide pipe 4.

[0074] It can be understood that the axis of the transfer funnel 2 is arranged vertically, and the axes of the first hinge shaft 31 and the second hinge shaft 51 should be arranged horizontally and parallel to the axis of the head roller 11 of the incoming belt conveyor 1. Corresponding sealing rings can be set at the first mounting hole and the second mounting hole to ensure sealing. When the material is impacted, the guide rod can slide back and forth along the axis of the corresponding mounting hole to realize the swing of the slide plate around the corresponding hinge shaft, which plays a better buffering and guiding role on the material, reduces the impact force, and prevents material blockage.

[0075] The upper ends of the first elastic vibration slide plate 3 and the second elastic vibration slide plate 5 can be hinged to the corresponding side wall through a heavy hinge, and a hinge seat can be fixed at the lower part of each elastic vibration slide plate, which is hinged to the corresponding guide rod through a pin. During operation, the first elastic vibration slide plate 3 and the second elastic vibration slide plate 5 are impacted unevenly by incoming materials, and the length of each spring is compressed, so that the first elastic vibration slide plate 3 and the second elastic vibration slide plate 5 are rotated around the corresponding hinge axis to adjust the change angle, forming a trapezoidal material discharge effect.

[0076] Preferably, the first elastic vibration slide plate 3 includes a first main board body and two first side boards located on both sides of the first main board body. The two first side boards and the first main board body are combined to form a first slide groove, and the bottom of the first slide groove constitutes a concave guiding surface.

[0077] The second elastic vibration slide plate 5 includes a second main board body and two second side boards located on both sides of the second main board body. The two second side boards and the second main board body are combined to form a second slide groove, and the bottom of the second slide groove is an inclined plate surface or an arc surface.

[0078] For the first elastic vibration slide plate 3, a trough structure surrounded on three sides is adopted, which is arranged in the transfer funnel 2 and located just in front of the discharge end of the incoming belt conveyor 1, so that the material contacts the concave guide surface in a tangential manner, thereby reducing the impact between the material and the first elastic vibration slide plate 3. The concave guide surface is preferably an arc surface, and the first side plates on both sides are preferably in a closing shape from top to bottom, which can gather the material to avoid scattering.

[0079] For the second elastic vibration slide plate 5, the bottom of the second chute is preferably an arc surface, and the upper end of the second elastic vibration slide plate 5 is bent and extended toward the discharge end of the discharge belt conveyor 7 to provide a better buffering effect on the material. The guide surface of the chute 4 specifically refers to the inner side wall portion of the circumferential side wall of the chute 4 on the side close to the feed end of the discharge belt conveyor 7 in the horizontal direction along the material conveying direction of the discharge belt conveyor 7, that is, according to Figure 1 What is shown in FIG. 1 is a portion of the circumferential side wall of the slide pipe 4 close to the left side.

[0080] Wear-resistant lining plates may be provided on the first main plate body of the first elastic vibration slide plate 3 and the second main plate body of the second elastic vibration slide plate 5 to increase the service life.

[0081] In the actual material conveying process, the conveying directions of the discharge belt conveyor 7 and the incoming belt conveyor 1 can be parallel to achieve the same-direction continuous transportation, or there can be a certain angle to achieve the redirected continuous transportation. In this embodiment, the part of the chute 4 close to the lower port is a closing structure with a diameter that gradually decreases downward, and the cross-section of the closing structure is a hexagon. By designing a hexagonal closing structure at the bottom of the chute 4, the incoming and discharging directions form a groove shape with the material contacting the chute 4 surface, which can make the incoming materials converge.

[0082] For the slide pipe 4, an arc-shaped slide pipe 4 can be used, or Figure 2 The structure shown in FIG. 1 is a structure in which the side walls are surrounded by a plurality of inclined plates.

[0083] The device in this embodiment is mainly suitable for dry materials, such as dry quenched coke, sintered ore, pelletized ore and any other dry materials, and is particularly suitable for the transportation and transfer of dry quenched coke.

[0084] From the observation and analysis of the blockage and dust problems generated at the actual belt conveyor transfer point, it is found that loose material is the main cause of these problems. It is very important to set the first elastic vibration slide plate 3 in the transfer funnel 2 to make the dry quenched coke converge. Through the discrete element simulation software EDEM, a specific analysis of the dry quenched coke transfer can be performed, which can simulate the sliding trajectory of the dry quenched coke. On this basis, the installation position and inclination angle of the first elastic vibration slide plate 3 in the transfer funnel 2 can be determined. The first spring 35 corresponding to the first elastic vibration slide plate 3 is adjusted to change the angle through the uneven impact of the dry quenched coke incoming material, which can effectively avoid material blockage in the transfer funnel 2.

[0085] According to the sliding track of dry coke quenching, the general shape of the slide pipe 4 can also be designed. The first group of second elastic vibration slide plates 5 are installed at the drop point of the slide pipe 4 impacted by dry coke quenching, and the dry coke incoming material falls on the middle part of the first group of second elastic vibration slide plates 5 after installation; the second group of second elastic vibration slide plates 5 are installed after the first group of second elastic vibration slide plates 5 are compressed to the limit position, and the dry coke incoming material falls on the middle part of the second group of second elastic vibration slide plates 5 after installation; and so on, the third group of second elastic vibration slide plates 5 are installed. The second spring 55 corresponding to the second elastic vibration slide plate 5 is adjusted to change the inclination angle by the uneven impact of the dry coke incoming material, which can effectively prevent the slide pipe 4 from being blocked.

[0086] The specific shapes and positions of the first elastic vibration slide plate 3, the chute 4 and the second elastic vibration slide plate 5 can be reasonably determined based on the analysis of the material sliding trajectory and the actual situation. By simulating the sliding trajectory of dry coke quenching, the installation position of the first elastic vibration slide plate 3 needs to accommodate all dry coke quenching. According to field experience, the top of the first elastic vibration slide plate 3 should not be lower than the top height of the maximum material flow of the head of the incoming belt conveyor 1, and the inclination angle of the first elastic vibration slide plate 3 should minimize the angle between the incoming material flow trajectory and the concave guide surface of the first elastic vibration slide plate 3. The upper end of the chute 4 can be connected to the bottom end of the transfer funnel 2 by flange bolts, and multiple second elastic vibration slide plates 5 are distributed in a stepped manner in the curved chute 4. The inner wall of the second elastic vibration slide plate 5 installed in the chute 4 should minimize the angle with the sliding trajectory of dry coke quenching.

[0087] In this embodiment, the incoming belt conveyor 1 and the outgoing belt conveyor 7 are both circular tube belt conveyors, and the head roller 11 in the head expansion section of the incoming belt conveyor 1 extends into the transfer funnel 2; the material guide trough structure 6 is installed on the tail expansion section of the outgoing belt conveyor 7, and the corresponding conveyor belt in the tail expansion section is a concave conveyor belt 71 surrounded by a bottom surface and two inclined side surfaces, and the bottom notch of the material guide trough structure 6 is arranged opposite to the concave conveyor belt 71.

[0088] The structure of the circular tube belt conveyor is an existing structure, including a head expansion section, a middle tube forming section and a tail expansion section. The material is conveyed in a closed manner in the tube forming section, which is more environmentally friendly.

[0089] Further, see Figures 5 to 9 , the guide trough structure 6 comprises:

[0090] Two groups of support frames 61 are distributed on both sides of the tail deployment section and connected to the corresponding frames of the tail deployment section (specifically, they are installed on the middle frame of the tail deployment section);

[0091] Two groups of inner inclined plates 62, the upper ends of the inner inclined plates 62 are connected to the corresponding support frame 61, the inner inclined plates 62 are located above the concave conveyor belt 71, and the lower ends of the inner inclined plates 62 are arranged close to the side of the concave conveyor belt 71, and the spacing between the two groups of inner inclined plates 62 gradually decreases from top to bottom;

[0092] A top sealing plate 63 is installed on the top of the two sets of inner inclined plates 62 to close the interval area between the two sets of inner inclined plates 62;

[0093] Two sets of end sealing plates 64 are respectively installed at the two ends of the top sealing plate 63 to close the two ends of the guide trough structure 6 in the length direction.

[0094] The top sealing plate 63, two sets of inner inclined plates 62 and two sets of end sealing plates 64 enclose a guide trough with an opening facing downward, the bottom notch facing the concave conveyor belt 71, and a docking port is provided on the top sealing plate 63, and is sealed and docked with the lower end of the chute 4. The entire guide trough structure 6 is installed at the feed end of the discharge belt conveyor 7, and can be enclosed with the concave conveyor belt 71 to form a basically closed space, effectively preventing dust from being generated when the material is transferred to the discharge belt conveyor 7.

[0095] As a preference, refer to Figure 6 and Figure 7 , the guide trough structure 6 also includes:

[0096] Two sets of outer sealing inclined plates 65, the outer sealing inclined plates 65 are connected to the corresponding support frame 61, and are supported and abutted against the outer surfaces of the corresponding sides of the concave conveyor belt 71;

[0097] The two sets of inner sealing inclined plates 66 , both sides of which can be in sealing contact with the outer surface of the corresponding inner inclined plate 62 and the inner surface of the corresponding side surface of the concave conveyor belt 71 .

[0098] The outer sealing inclined plate 65 is used to support the side of the concave conveyor belt 71, and the inner sealing inclined plate 66 is used to press the side of the concave conveyor belt 71. The cooperation of the sealing inclined plates on both sides can achieve double-layer sealing, effectively seal the gaps that may exist inside and outside the side of the concave conveyor belt 71, and achieve complete closure as much as possible, which is more effective in preventing dust and is more environmentally friendly.

[0099] The inner sealing inclined plate 66 is pressed on the side of the concave conveyor belt 71. In order to avoid damage to the concave conveyor belt 71, the inner sealing inclined plate 66 preferably adopts a flexible plate. Its specific shape can be determined according to needs, as long as it can play a good sealing role. For example, in this embodiment, the inner sealing inclined plate 66 adopts a double-layer composite anti-overflow skirt plate (existing structure), which includes a straight plate 661 and a skirt 662. The straight plate 661 is attached to the outer surface of the inner inclined plate 62, and the skirt 662 is in close contact with the side of the concave conveyor belt 71. The lower end of the straight plate 661 can also be in close contact with the side of the concave conveyor belt 71, and the sealing performance is good. For the outer sealing inclined plate 65, a wear-resistant slide plate is generally used, and the material can be, for example, ultra-high molecular polyethylene.

[0100] In order to facilitate the installation and positioning of the inner sealing inclined plate 66, a plurality of clamps 663 are provided on the outside of the inner inclined plate 62, and the inner sealing inclined plate 66 can be slidably abutted against the inner inclined plate 62; a pressure plate 664 is pressed on the upper outer surface of the inner sealing inclined plate 66, and the pressure head of each clamp 663 can press the pressure plate 664 tightly.

[0101] The pressing plate 664 can be made of angle steel, for example, and taking the double-layer composite anti-overflow skirt as an example, the pressing plate 664 is pressed on the outer surface of the straight plate 661, and a plurality of clamps 663 are arranged at intervals along the length direction of the inner sealing inclined plate 66 (i.e., the material conveying direction of the discharge belt conveyor 7), and the pressing plate 664 is pressed and fixed to fix the inner sealing inclined plate 66. The inner sealing inclined plate 66 is designed as a slidable structure, and is pressed by the clamp 663. When the inner sealing inclined plate 66 is worn to a certain extent, the inner sealing plate can be adjusted downward to ensure close contact with the side of the concave conveyor belt to ensure the sealing effect.

[0102] Further, see Figures 6 to 8The material guide trough structure 6 also includes: two groups of outer protective plates 67, the outer protective plates 67 include a first plate body 671 and a second plate body 672 connected in an L shape, the first plate body 671 is abutted against the outer surface of the outer sealing inclined plate 65 and is connected to the corresponding support frame body 61; the second plate body 672 is inclined from the outer sealing inclined plate 65 to the inner inclined plate 62, and its upper end is connected to the upper part of the inner inclined plate 62.

[0103] When connected, the first plate body 671 can be connected to the corresponding support frame body 61 through fasteners, the upper end of the second plate body 672 can be connected to the inner inclined plate 62 through fasteners, and the outer sealing inclined plate 65 can be connected to the first plate body 671 through fasteners, and the fasteners here can be bolts. The outer protective plate 67 can play a secondary sealing role to achieve a better sealing effect, and can also support the outer sealing inclined plate 65.

[0106] After the material enters the guide trough structure 6 through the chute 4, it falls onto the concave conveyor belt 71 under the guidance of the two sets of guide slides 68. The adjusting rod 621 can be a screw, for example. By adjusting the length of the adjusting rod 621 extending out of the inner inclined plate 62, the guide slide 68 can be tilted at different angles, allowing the material to move to the middle better and fall to the middle position of the conveyor belt better.

[0107] Generally, the guide slide plate 68 includes a wear-resistant lining plate 681 and a wear-resistant ceramic plate 682 which are stacked and arranged inside and outside and can be disassembled. When the inner surface of the guide slide plate 68 is worn to a certain extent, the wear-resistant lining plate 681 can be replaced, which is more convenient.

[0117] The first side plate assembly and the second side plate assembly are both formed by connecting a plurality of push-pull movable baffles, and observation windows are arranged on the push-pull movable baffles.

[0118] The head unfolding section of the incoming belt conveyor 1 and the push-pull movable baffles on both sides are arranged in the corridor of the incoming belt conveyor 1.
