Description

Technical Field

[0001] The invention relates to the technical field of silicon-manganese alloy processing, and more specifically, to a dust removal device for a silicon-manganese alloy batching trolley. Background Art

[0002] The smelting of silicon-manganese alloy is usually carried out in its smelting electric arc furnace. In order to control the stability of the reaction in the furnace and the melting efficiency, it is necessary to add the prepared smelting raw materials at the furnace mouth at a regular time and in a quantitative manner. There are many furnace mouths and they are distributed at different positions on the furnace top. Therefore, the materials are usually unloaded from multiple furnace mouths through a batching trolley with tracks.

[0003] At present, the batching trolley moves on the track and transports the raw materials to the furnace mouth for unloading. The raw materials are weighed by a weighing belt and then lowered to the furnace mouth. During this period, the raw materials will generate dust. Therefore, bag dust collectors are often used to collect dust between the batching trolley and the furnace mouth to avoid excessive dust. However, in order to ensure the temperature in the furnace, the furnace mouth is mostly an open and close type furnace mouth, which is closed under normal circumstances. When feeding is required, the furnace mouth is opened. When the furnace mouth is opened, the high-temperature airflow in the furnace carries the dust and sprays it upward, which will be continuously sucked out by the dust removal equipment, thereby affecting the temperature in the furnace. In addition, due to the high temperature in the furnace, the high-temperature airflow sprayed from the furnace mouth can easily increase the adhesion between the dust particles, causing the dust to aggregate or agglomerate during the feeding process, affecting the fluidity of the dust. Dust with larger particles will further burden the filter of the dust removal equipment, resulting in the need for frequent shutdown and cleaning of the dust removal equipment, affecting the smelting efficiency.

[0019] The beneficial effects of the present invention are:

[0020] 1.

The separately arranged feed rack can also prolong the falling time of the raw materials and improve the dust removal efficiency.

[0021] 2. The present invention sets an impeller disk, and uses the high-temperature airflow sprayed upward from the furnace mouth as a power to drive the impeller disk to rotate. In conjunction with the cone blocks on the surface of the impeller disk, the dust carried by the high-temperature airflow from the furnace mouth is scattered around and falls onto the surface of the collecting plate. The collection plate is driven to rotate synchronously by the rotation of the impeller disk, and the dust is sent to the collection assembly for collection in conjunction with the stripping plate. The dust is rotated and scattered and cooled by the rotatable collecting barrel in the collection assembly, and then discharged outwardly through the collecting piece, thereby reducing the burden of dust caused by high-temperature agglomeration on the dust removal equipment.

[0022] 3. The present invention sets a baffle, which rotates and rises regularly to retain the raw materials rolling down from the feed rack. After a certain amount of raw materials are retained, the baffle rotates back to the original position to lower the part of the raw materials into the furnace mouth. Concentrating part of the raw materials for lowering can better control the amount of raw materials lowered at one time, effectively avoiding the problem of inconsistent melting progress before and after and poor reaction uniformity in the furnace due to intermittent lowering of the raw materials. Lowering the raw materials in sections can also effectively reduce the intensity of the high-temperature gas in the furnace gushing out of the furnace mouth due to the high-temperature explosion when all the raw materials are added to the furnace at one time.

DETAILED DESCRIPTION

[0035] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0036] In one embodiment of the present invention, a dust removal device for a silicon-manganese alloy batching trolley is disclosed, referring to Figure 1 , Figure 3 and Figure 4 As shown, it includes: a feeding trolley body 1, the feeding trolley body 1 is used to hold the raw materials required for silicon-manganese alloy smelting, and a plurality of weighing belt groups 12 are installed in the feeding trolley body 1. The weighing belt group 12 is composed of a belt, a roller, a weighing sensor and a driving motor. The driving motor is used to drive the roller to rotate and the belt transmission, and the weighing sensor is used to weigh the raw materials on the surface of the belt. It is a prior art and will not be repeated here. A partition 11 is arranged in the feeding trolley body 1, and the partition 11 divides the feeding trolley body 1 into The feeding trolley body 1 is divided into two independent chambers, and a weighing belt group 12 is arranged in each chamber, so two portions of raw materials can be weighed at the same time. A transport component is installed at the bottom of the feeding trolley body 1 to facilitate the feeding trolley body 1 to transport the raw materials. Specifically, the feeding trolley body 1 can drive the raw materials to move and transport through the transport component, so that the raw materials can be carried between the furnace openings at different positions on the furnace top for movement and feeding. At least one set of feeding racks 3 is hinged on the surface of the feeding trolley body 1. Two sets of feeding racks 3 are arranged in this article. The feeding racks 3 can be placed on the feeding trolley body 1. One side rotates, and is respectively arranged on both sides of the feeding trolley body 1. The feeding frame 3 is tilted. The feeding trolley body 1 is connected to the feeding frame 3 through an electric push rod 31. The fixed end of the electric push rod 31 is hinged on one side of the feeding trolley body 1, and the output end of the electric push rod 31 is hinged on one side of the feeding frame 3. Through the output of the electric push rod 31, the feeding frame 3 can be driven to rotate on the surface of the feeding trolley body 1, thereby adjusting its feeding direction. The interior of the feeding frame 3 is connected to the interior of the feeding trolley body 1, and the feeding frame 3 is fixed away from the side of the feeding trolley body 1. A feeding block 4 adapted to the feeding port is connected, and the feeding port is the furnace port. A detection cavity 41 and an isolation cavity 42 are respectively opened in the feeding block 4. The isolation cavity 42 is used to directly contact the furnace port and the high-temperature airflow ejected from the furnace port. The interior of the feed rack 3 is connected with the interior of the feeding block 4, and the internal size of the feed rack 3 gradually decreases when it is close to the opening of the connection position with the feeding block 4, so as to facilitate guiding the raw materials into the feeding block 4, and the bottom of the feed rack 3 is in a sieve shape, and a collecting piece for collecting dust is fixedly connected to the bottom of the feed rack 3.

[0037] The partition assembly is arranged in the feeding block 4, and the partition assembly includes an impeller disk 421. A plurality of fan blades are arranged at the bottom of the impeller disk 421. When the furnace mouth is opened and the high-temperature gas rises and impacts the impeller disk 421, the fan blades will be pushed, thereby driving the impeller disk 421 to rotate. In this process, the fan blades can disperse the dust and debris mixed in the high-temperature airflow to the surroundings. A rotating block 423 is fixedly connected to the top of the impeller disk 421. The rotating block 423 is movably connected between the detection chamber 41 and the isolation chamber 42. An injection box 412 is installed in the detection chamber 41. The lower end of the injection box 412 is fixed A plurality of gas nozzles are fixedly connected, and a gas valve for controlling the opening or closing of the gas nozzle is installed in the jet box 412. The plurality of gas nozzles are arranged above the opening connecting the feeding rack 3 and the feeding block 4. An air pipe 413 is installed on the top of the jet box 412. The top of the air pipe 413 passes through the feeding block 4 and is connected to an external air source device. Gas with a certain pressure is introduced into the air pipe 413 through the external air source device, and when the air valve is opened, the gas is ejected downward through the plurality of gas nozzles to form an air curtain. A detection component adapted to the rotating block 423 is installed in the detection chamber 41.

[0038] The bottom of the feeding block 4 is set to be conical, and a through hole adapted to the feed port is opened. The through hole is used to pass the raw materials, and the size of the through hole is adapted to the size of the furnace mouth. The furnace mouth can be inserted into the through hole from the bottom. Since the bottom of the feeding block 4 is set to be conical, a groove that is wide at the top and narrow at the bottom is formed around the through hole. The groove is used to store dust carried by the high-temperature airflow ejected from the furnace mouth.

[0039] Specifically, by setting the feeding rack 3 and the feeding block 4, the original method of unloading materials from the bottom of the batching trolley is changed to a method of conveying through the feeding rack 3 on one side and feeding by the feeding block 4. In this process, the feeding rack 3 which is set to be inclined and has a certain length can change the original direct falling method of the raw materials into a rolling method, so that the dust on the surface of the raw materials is shaken off by vibration, and the dust is sieved to the bottom of the collecting piece through the screen at the bottom of the feeding rack 3 for collection and dust removal, and the isolation chamber 42 is effectively blocked from the external air by the setting of the partition component in the feeding block 4, and the gas is sprayed through the gas nozzle for the connecting port between the isolation chamber 42 and the internal space of the feeding rack 3 to form an air curtain to isolate the internal and external airflows, so as to avoid the high-temperature gas sprayed from the furnace mouth from leaking from here and affecting the temperature in the furnace, and the setting of the air curtain will not block the solid raw materials, and the raw materials can pass through the air curtain normally and enter the isolation chamber 42, and finally enter the furnace.

[0040] It is worth noting that in this article, a feeding rack 3 is arranged on both sides of the feeding vehicle body 1, so two portions of raw materials can be weighed at the same time, and the materials can be transported and fed separately through the feeding racks 3 on both sides. Specifically, the feeding vehicle body 1 receives the raw materials under the feeding rack, and after weighing them through the weighing belt group 12, the feeding vehicle body 1 moves on the track to between two adjacent furnace openings, and pushes the feeding rack 3 to rotate to a direction suitable for the furnace opening through the output of the electric push rod 31, and accordingly moves the feeding block 4 to the top of the target furnace opening. After the feeding racks 3 on both sides have completed the directional movement, the weighed raw materials can be gradually transported to the feeding rack 3 through the transmission of the weighing belt group 12, and the two furnace openings can be fed simultaneously through the feeding racks 3 on both sides, or after feeding a single furnace opening, the adjacent furnace opening can be fed immediately. Compared with stopping to feed at each furnace opening, the feeding efficiency can be effectively improved and the number of stops can be reduced.

[0041] Correspondingly, since the feed frame 3 can rotate on both sides of the feeder body 1, in order to prevent dust from leaking from the hinge between the feed frame 3 and the feeder body 1 during the process of the raw materials in the feeder body 1 moving into the feed frame 3, a dustproof cloth or rubber sleeve is covered at the hinge between the feed frame 3 and the feeder body 1 to prevent dust leakage.

[0042] refer to Figure 4 as well as Figure 5 As shown, in this embodiment, the bottom of the feeding block 4 is rotatably connected to a collecting plate 425, which is set in the groove. The collecting plate 425 is used to collect dust. Specifically, the surface of the collecting plate 425 can be set to a rough surface to facilitate the attachment of dust and impurities. The collecting plate 425 is connected to the impeller plate 421 through a plurality of connecting rods 424. One end of the connecting rod 424 is fixedly connected to the impeller plate 421, and the other end is limitedly slidably connected to the inner wall of the collecting plate 425. Specifically, refer to Figure 6 As shown, the inner wall of the collecting plate 425 is provided with a slot, and the connecting rod 424 slides in the slot. When the impeller plate 421 rotates, the collecting plate 425 can be driven to rotate synchronously through the connecting rod 424.

[0043] Furthermore, in this embodiment, a cone block 422 is fixedly connected to the bottom of the impeller disk 421, and the cone block 422 can rotate with the impeller disk 421. During the rotation, the cone block 422 can bounce the debris and dust carried by the high-temperature airflow ejected from the furnace mouth to the surroundings, and evenly drop them into the collection plate 425 in the groove.

[0044] refer to Fig. 9 , Fig.10 as well as Fig.11As shown, in the present embodiment, a collecting assembly for storing impurities ejected from the furnace mouth is further included, the collecting assembly includes an auxiliary chamber 448 opened inside the feeding block 4, the auxiliary chamber 448 is opened on one side of the isolation chamber 42, a material receiving box 44 is slidably connected inside the auxiliary chamber 448, a material receiving barrel 441 is provided inside the material receiving box 44, both ends of the material receiving barrel 441 are provided, the material receiving barrel 441 is connected to the interior of the isolation chamber 42, and a stripping plate 432 for guiding dust into the material receiving barrel 441 is fixedly connected to the inner wall of the isolation chamber 42 near the collecting plate 425.

[0045] Specifically, when the collecting plate 425 rotates, the dust and impurities adhered to its surface will move with it, and when it moves to the position of the stripping plate 432, it will be stripped from the surface of the collecting plate 425 by the stripping plate 432 and guided into the collecting cylinder 441 in the collecting box 44, thereby completing the collection of dust and impurities carried by the gas ejected from the furnace mouth.

[0046] Furthermore, in the present embodiment, a connecting block 43 is fixedly connected to the inner wall of the isolation chamber 42 near the connection point between the feeding rack 3 and the feeding block 4. The connecting block 43 is used to support the raw materials entering from the feeding rack 3 and facilitate the raw materials to enter the material through hole and further enter the furnace mouth. An air cavity 431 adapted to the gas nozzle is provided inside the connecting block 43, and a grid for filtering dust is provided on the top of the air cavity 431. Specifically, side panels can also be provided on both sides of the connecting block 43 to prevent the raw materials from rolling to the side on the surface of the connecting block 43, so as to facilitate guiding the raw materials to roll accurately into the furnace mouth. A ventilation groove 443 is provided in the material receiving box 44, and the lower end of the air cavity 431 is connected to the auxiliary cavity 448. Under normal conditions, the lower end of the air cavity 431 is connected to the inside of the ventilation groove 443. A plurality of fixed blades 442 are installed on the arc surface of the receiving barrel 441, and the receiving barrel 441 is rotatably connected in the receiving box 44, and the fixed blades 442 are provided in the ventilation groove 443.

[0047] Specifically, when the gas nozzle sprays high-speed gas to form an air curtain, since the high-speed gas is sprayed downward, it will enter the air cavity 431 opened on the surface of the lower connecting block 43, and enter the auxiliary cavity 448 through the air cavity 431. Since under normal conditions, the air cavity 431 is connected with the ventilation groove 443, the gas will enter the ventilation groove 443 and generate thrust for the fixed fan blades 442 in the ventilation groove 443, thereby driving the entire collecting barrel 441 to rotate. Since the collecting barrel 441 collects dust and impurities carried by the high-temperature airflow ejected from the furnace mouth, the agglomeration rate is relatively high. During the rotation of the collecting barrel 441, the internal dust and impurities collide and roll with each other, thereby disintegrating and decomposing into smaller dust particles, which is convenient for subsequent filtration by dust removal equipment.

[0048] In a further embodiment, the arc surface of the material receiving barrel 441 is provided with a plurality of holes for air flow to pass through, and the holes may be circular, diamond-shaped, square, etc. In order to prevent dust and impurities from passing through the holes and separating from the material receiving barrel 441, the material receiving barrel 441 is arranged to be in close contact with the inner wall of the material receiving box 44. Therefore, even if dust and impurities are in the holes, they will move, collide and disintegrate with the rotation of the material receiving barrel 441. The ventilation groove 443 is connected to the interior of the material receiving barrel 441 through a plurality of through holes 444. One end of the through hole 444 is connected to the interior of the ventilation groove 443, and the other end is connected to the interior of the material receiving box 44. Since the surface of the material receiving barrel 441 is provided with holes, the air flow can also enter the interior of the material receiving box 44 through the holes. An adjustment component for discharging dust from the material receiving barrel 441 is also included.

[0049] Specifically, when the fixed fan blades 442 are driven by the airflow to rotate the collecting barrel 441, the remaining airflow in the ventilation groove 443 will enter the collecting box 44 through a number of through holes 444, and enter the interior of the collecting barrel 441 through the holes on the surface of the collecting barrel 441, dissipating the heat of dust and impurities during the rolling or collision process, thereby cooling the dust and impurities, facilitating their disintegration and separation into small particles of impurities and dust, thereby improving the disintegration efficiency and the dust removal efficiency of subsequent dust removal equipment.

[0050] In this embodiment, the adjustment component includes a guide rail 445 fixedly connected to the top of the material receiving box 44, and a baffle 446 is hingedly connected to the bottom of the feed rack 3 near the top of the guide rail 445. The size of the baffle 446 is adapted to the internal size of the feed rack 3. Under normal conditions, the baffle 446 coincides with the bottom plane of the feed rack 3. When coincident, the baffle 446 does not affect the normal passage of the raw materials. A pull plate 447 is fixedly connected to the bottom of the baffle 446, and the lower end of the pull plate 447 is connected to the guide rail 445 through a slider. The slider slides on the surface of the guide rail 445, and both ends of the slider are fixedly connected to the pull plate 447. A motor B449 is fixedly connected to one side of the feed rack 3, and the output end of the motor B449 is fixedly connected to the baffle 446 and the hinge shaft of the feed rack 3.

[0051] Furthermore, the collecting member includes a partition bin 32 fixedly connected to the bottom of the feed rack 3, and a collecting chamber 321 is provided on a side of the partition bin 32 close to the feeding block 4. The dust and impurities collected in the partition bin 32 will roll down to the collecting chamber 321 under the force of gravity for collection. A connecting pipe 322 is fixedly connected to one side of the collecting chamber 321, and the connecting pipe 322 is connected to the inside of the collecting chamber 321, and the end of the connecting pipe 322 away from the collecting chamber 321 is connected to an external dust suction device. Through the external dust suction device, such as a bag dust collector, an electrostatic dust collector, etc., a negative pressure suction force is generated on the connecting pipe 322, and then the dust and impurities in the collecting chamber 321 are sucked out, and subsequent processing is carried out. The collecting chamber 321 is connected to the auxiliary chamber 448 through a dust hole, and the dust hole is adapted to the receiving barrel 441.

[0052] Specifically, when the motor B449 outputs, it will drive the baffle 446 to rotate axially, and then the baffle 446 will rotate and rise to cross the feeding direction of the feeding rack 3. At this time, the baffle 446 will block part of the raw materials rolling down from the top of the feeding rack 3, and gradually increase the amount of raw materials during the continuous blocking process of the baffle 446. At the same time, the rotation of the baffle 446 will drive the pull plate 447 to move up, causing the slider at the bottom of the pull plate 447 to slide on the surface of the guide rail 445, thereby pulling up the entire receiving box 44, driving the receiving cylinder 441 and the internal The dust moves upward, and the connection port of the inside of the material receiving barrel 441 and the isolation chamber 42 are offset and blocked by the material receiving box 44. At this time, the dust in the isolation chamber 42 will not be able to enter the auxiliary chamber 448. At the same time, through the upward movement of the material receiving box 44, the end of the material receiving barrel 441 away from the isolation chamber 42 is connected to the dust hole. At this time, the inside of the material receiving barrel 441 is connected to the collection chamber 321. Under the suction force generated by the external dust removal equipment, the dust and impurities in the material receiving barrel 441 that are cooled, disintegrated and dispersed are sucked out, and then processed by the external dust removal equipment.

[0053] Subsequently, after the dust and impurities inside the material receiving barrel 441 are sucked out, the motor B449 reverses and the baffle 446 rotates back to the normal position, no longer blocking the running path of the raw materials. At this time, part of the gathered raw materials will roll down at the same time, enter the isolation chamber 42, and finally enter the furnace through the furnace mouth. By centrally blocking part of the raw materials and then lowering them, the amount of raw materials lowered at a time can be better controlled, and the problem of uneven melting progress before and after and poor reaction uniformity in the furnace caused by intermittent lowering of raw materials can be effectively avoided. The reaction efficiency in the furnace is improved to a certain extent, and the raw materials enter in stages to reduce the impact of the rising hot air flow generated by the deflagration during the entry process on the impeller disk 421. At the same time, in the process of the baffle 446 gradually rotating back to the normal position, under the action of the pull plate 447, the material receiving box 44 will gradually move down, so that the material receiving barrel 441 can resume the connection with the inside of the isolation chamber 42, and then continue to collect the dust and impurities pushed up by the high-temperature gas in the furnace.

[0054] It is worth noting that after the material receiving box 44 moves down to the initial position, the dust hole used to connect the auxiliary cavity 448 with the collecting cavity 321 will be blocked by the pull plate 447, thereby preventing the dust in the collecting cavity 321 from entering the auxiliary cavity 448.

[0055] refer to Figure 7 As shown, in this embodiment, the detection component includes two infrared sensor heads 411 fixedly connected to the inner wall of the detection cavity 41, the two infrared sensor heads 411 are distributed up and down on the inner wall of the detection cavity 41, the two infrared sensor heads 411 are electrically connected to the gas valve, and a controller is provided in the gas valve.

[0056] Specifically, when the furnace mouth is opened, the high-temperature rising gas in the furnace will impact the impeller disc 421 upward, thereby pushing the impeller disc 421 upward. Under normal conditions, only the infrared sensing head 411 near the bottom senses the rotating block 423. After the impeller disc 421 is pushed upward by the rising airflow, the rotating block 423 will be sensed by the infrared sensing head 411 near the top, while the infrared sensing head 411 near the bottom cannot sense the rotating block 423. At this time, the infrared sensing head 411 above transmits a signal to the gas valve, and the internal controller of the gas valve controls the gas valve to open, thereby allowing the gas inside the gas pipe 413 to The body enters several gas nozzles through the gas valve and is ejected, and the air flow is continuously output to the air pipe 413 through the external gas source equipment, so that the gas nozzle forms an air curtain downward. Therefore, the air curtain will only be generated when the impeller disk 421 rises, that is, the furnace mouth is opened, and the high-temperature gas lifts the impeller disk 421 upward, which effectively saves resources. After the furnace mouth is completed and closed, the impeller disk 421 falls due to gravity, so that the rotating block 423 is re-sensed by the infrared sensing head 411 below, and the infrared sensing head 411 below will transmit the signal to the gas valve, and the gas valve is closed through the controller inside the gas valve to stop generating the air curtain.

[0057] The transport component includes a base 2 slidably connected to the bottom of the feeding trolley body 1, and the base 2 slides at the bottom of the feeding trolley body 1 with upper and lower limits. The base 2 is connected to the feeding trolley body 1 through a cylinder 22. The fixed end of the cylinder 22 is fixed on the base 2, and its output end is fixed on the bottom of the feeding trolley body 1. When the cylinder 22 outputs, it will drive the entire feeding trolley body 1 to rise in height. The bottom of the base 2 is rotatably connected to a plurality of rotating shafts, and both ends of the rotating shafts are rotatably connected to rollers 21. The rollers 21 are adapted to the transport track so that the feeding trolley body 1 can move on the track. A motor A23 is installed on one side of the base 2, and the output end of the motor A23 is connected to one of the rotating shafts through a synchronous belt 231. The synchronous belt 231 is transmission-connected to the output shaft of the motor A23 and the rotating shaft. When the motor A23 outputs, it is transmitted through the synchronous belt 231 to drive one of the rotating shafts to rotate, thereby driving the rollers 21 to roll on the track, so that the feeding trolley body 1 can move.

[0058] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation mode. The above-mentioned specific implementation mode is merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make more forms of equivalent embodiments, all of which are within the protection of this embodiment.
