Description

Technical Field

[0001] This invention relates to the field of refractory brick preparation and molding, and in particular, to a refractory brick unpacking system. Background Technology

[0002] The refractory brick casting process involves mixing various powdered raw materials, then pouring the mixture into an electric arc furnace for melting. Once the powder has melted into a liquid, it is poured into an insulated box for cooling and heat preservation. After the refractory bricks have set, they are removed from the insulated box. The structure of the insulated box is as follows: Figure 1 As shown.

[0003] The process of removing refractory bricks from their boxes typically involves placing the insulated box on a platform and then using a crane to lift the outer shell of the box, separating it from the insulating sand, sand mold, and refractory bricks. After the outer shell is lifted, the insulating sand scatters onto the platform, and the sand mold falls to the ground along with the refractory bricks. The sand mold breaks upon impact, and the remaining sand attached to the refractory bricks is manually shoveled away to separate the bricks. While the insulating sand needs to be recycled, it contains fragments of sand from the broken sand mold and other impurities. The lifting of the outer shell and the falling of the sand mold and refractory bricks also generate significant amounts of dust, harming the environment.

[0004] Traditional unloading systems are installed above ground, with the unloading system's work platform about 4 meters above the ground. If the crane is not operated properly, it may cause the insulated box to hit the operator. The operator will need to escape from the 4-meter-high operating platform to the ground. This is very inconvenient, as the operator has to climb down the ladder from the platform to the ground. At the same time, the operator is prone to secondary accidents due to collisions with the guardrails during the escape.

[0005] Currently, in terms of dust removal, the equipment is placed in an open space, and dust extraction is only carried out near the material feeding system. Because the space is not sealed, the dust removal effect is very poor. Summary of the Invention

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0031] Reference Figure 2-3 A preferred embodiment of the present invention provides a refractory brick unloading system, installed in an installation space below the workshop floor, comprising: a material feeding and sorting conveying system, a screening and unloading system, an unloading and lifting system 70, and a dust removal system 80 arranged sequentially and connectedly, and an outer cover 60 covering the material feeding and sorting conveying system and the screening and unloading system. The upper feed end of the material feeding and sorting conveying system extends upward beyond the outer cover 60 to allow the insulation boxes to be processed to enter. The material feeding and sorting conveying system is used to sort out the insulation sand in the insulation boxes and convey the insulation sand upward to the screening and unloading system. The screening and unloading system includes multiple receiving frames 51. The screening and unloading system is used to vibrate to automatically separate the insulation sand into layers according to particle size, and to convey the insulation sand of different layers to different receiving frames 51, and to allow the full receiving frames 51 to enter the unloading and lifting system 70 sequentially. The unloading and lifting system 70 is used to lift the receiving frames 51 that have entered it sequentially upward to the workshop floor. The dust removal system 80 is connected to the outer cover 60 to draw and collect the dust generated during the operation of the material sorting and conveying system and the screening and discharge system.

[0032] The method of using the refractory brick unloading system of the present invention is as follows:

[0033] 1. Screening and Packing of Insulating Sand: First, the insulating box is fed into the support plate of the material sorting and conveying system via a crane from the upper feed end. Then, the outer shell of the insulating box is manually lifted off, and the insulating sand falls onto the support plate. At the same time, refractory bricks and sand molds are also pushed onto the support plate. Next, the unbroken sand molds and refractory bricks are manually lifted out of the material sorting and conveying system. The insulating sand undergoes its first sorting under the action of the material sorting and conveying system, and the sorted insulating sand is conveyed upward to the screening and discharge system. The insulating sand in the screening and discharge system undergoes a second screening and stratification according to particle size under the action of vibration, and the insulating sand of different layers is then conveyed to different receiving frames 51. After the receiving frames 51 are full, they are conveyed to the discharge lifting system 70 under the action of the screening and discharge system. Finally, the receiving frames 51 are lifted to the workshop floor by the action of the discharge lifting system 70, and the operators hoist the receiving frames 51 to the storage area.

[0034] 2. Dust generated during material discharge: The dust generated during the operation of the material discharge system and the screening and discharge system is mainly sucked out of the outer cover 60 and collected by the dust removal system 80.

[0035] The refractory brick unloading system of this invention offers enhanced operator safety: Traditional unloading systems are installed above ground, with the work platform approximately 4 meters above the ground. Improper operation can easily cause the insulation box to collide with the operator, requiring the operator to escape from the 4-meter-high platform, a difficult and potentially secondary accident. In contrast, the unloading system of this invention is installed below the workshop floor, allowing operators to work from the floor. In case of misoperation, the operator can quickly escape the site. Furthermore, the insulation sand can be reused after secondary screening, saving resources and protecting the environment: This invention's system features two screening stages: a material sorting and conveying system to separate the insulation sand from large particles; and a screening and discharge system to remove non-compliant materials. Small-particle sand is screened out, and the insulating sand can be reused after secondary screening, which is beneficial to saving resources and protecting the environment. Dust generated during the production process is effectively treated, which is beneficial to environmental protection. The box-out system of this invention is installed in the installation space below ground level to ensure that dust does not drift into the production workshop. An outer cover 60 is set at the dust-generating parts such as the material sorting and conveying system and the screening and discharge system. The outer cover 60 is connected to the dust removal system 80. The suction generated by the dust removal system 80 during operation will draw the dust out of the outer cover 60, and the dust will eventually enter the dust removal system 80 for collection or discharge. In the refractory brick box-out system of this invention, the material sorting and conveying system, the screening and discharge system, the discharge lifting system 70, and the dust removal system 80 are all automated, so the box-out system of this invention has a high degree of automation and high operational safety.

[0036] Optionally, such as Figure 2 As shown, the material sorting and conveying system includes a material sorting device 20 and a belt conveyor 30, which are vertically spaced and supported on the ground foundation of the installation space. The upper feed end of the material sorting device 20 extends upward through an outer cover 60. The material sorting device 20 is used to automatically sort out the insulating sand and discharge it downward from its discharge end. The feed end of the belt conveyor 30 is located below the discharge end of the material sorting device 20, and is used to convey the insulating sand that falls onto it upward to the screening and discharge system.

[0037] In this optional solution, such as Figure 3 and Figure 5 As shown, the material sorting device 20 includes a material unloading system frame 21 vertically supported on a ground foundation, a thermal insulation sand sorting plate 22 horizontally supported on the material unloading system frame 21, a receiving hopper 23 connected to the material unloading system frame 21 and located below the thermal insulation sand sorting plate 22, and a vibrating feeder 24 located at the discharge end of the receiving hopper 23. The thermal insulation sand sorting plate 22 supports the thermal insulation box and is flush with the workshop floor, and has sorting holes for the thermal insulation sand to pass through. The receiving hopper 23 is used to collect the thermal insulation sand sorted by the thermal insulation sand sorting plate 22. During operation, the operator first hoists the insulation box onto the insulation sand sorting plate 22 using a crane. Then, the operator lifts the outer shell of the insulation box, causing the insulation sand to fall onto the insulation sand sorting plate 22. Refractory bricks and sand molds are pushed onto the insulation sand sorting plate 22. The operator then lifts the unbroken sand molds and refractory bricks out of the material discharge and sorting device 20. The insulation sand sorting plate 22 has equally spaced sorting holes according to the size of the insulation sand. The insulation sand falls through the sorting holes into the receiving hopper 23 below. Guided by the receiving hopper 23, the insulation sand falls into the vibrating feeder 24 at its outlet. In this optional scheme, the vibrating feeder 24 is a commonly used device on the market that uses vibration to feed materials, which can control the discharge speed of the insulation sand. In the material sorting device 20 of the present invention, the safety of operators is improved: the traditional box discharge system is installed above the ground, and the working table of the material discharge system is about 4 meters above the ground. If the crane is not operated properly, it is easy to cause the insulation box to hit the operator. The operator needs to escape from the 4-meter-high operating platform to the ground, which is very inconvenient and may cause secondary accidents. The present invention installs the box discharge system in the installation space below the ground, and the working table of the material discharge system, that is, the insulation sand sorting plate 22, is flush with the ground. If the crane is not operated properly, the operator can quickly escape the scene.

[0038] Furthermore, such as Figure 5As shown, the material sorting device 20 also includes two air ducts 25 constructed on opposite sides of the insulating sand sorting plate 22, and air guide hoods 26 installed on the top of each air duct 25 and extending along the length of the air duct 25 to guide the incoming air. The two air ducts 25 are respectively connected to the dust removal system 80. The corresponding surfaces and top surfaces of the two air ducts 25 are respectively provided with openings extending along their length, and grid plates 27 are installed in the openings to allow dust generated during material discharge to enter the air ducts 25. In this optional solution, the grid plates 27 can not only effectively prevent large particles from entering the air ducts 25, but also, due to their high structural strength, can effectively protect the air ducts 25 from damage when the insulating box is lifted.

[0039] In this optional solution, such as Figure 3 and Figure 5 As shown, the belt conveyor device 30 includes a conveyor system frame 31 and a conveyor system base 32, which are spaced apart and supported on the ground foundation; a belt conveyor 33 for conveying insulating sand upwards; and a conveyor system hopper 34 for discharging the conveyed insulating sand. The conveyor system base 32 is located below the receiving hopper 23, and the height of the conveyor system frame 31 is higher than that of the conveyor system base 32. The belt conveyor 33 is mounted on the conveyor system base 32 and the conveyor system frame 31. The conveyor system hopper 34 is fixed to the top of the conveyor system frame 31 and is connected to the output end of the belt conveyor 33. In a specific embodiment of this optional solution, the belt conveyor 33 is a conventional belt conveyor with a corrugated baffle conveyor belt on both sides and spacers on the surface of the belt. During operation, the vibrating feeder 24 is selected according to the discharge efficiency requirements. Under the action of vibration, the vibrating feeder 24 conveys the insulating sand to the corrugated baffle conveyor belt of the belt conveyor 33. The corrugated baffle conveyor belt, driven by the power of the conveyor system, conveys the insulating sand to the conveyor system hopper 34.

[0040] Optionally, such as Figure 3 and Figure 5 As shown, the screening and discharge system includes a vibrating screen 40 and a material frame conveyor 50, which are spaced apart and supported on the ground foundation. The inlet end of the vibrating screen 40 is connected to the outlet end of the belt conveyor 30, so as to vibrate and automatically stratify the insulating sand entering it according to its particle size, and then feed the stratified insulating sand into the material frame conveyor 50 respectively. The material frame conveyor 50 includes multiple receiving frames 51, which are used to sequentially move and convey the receiving frames 51 to the discharge lifting system 70 after they are full.

[0041] In this optional solution, such as Figure 3 and Figure 5As shown, the vibrating screening device 40 includes a screening machine frame 41 vertically supported on a ground foundation, a screening machine body 42 mounted on the screening machine frame 41, and a screening machine hopper 43 mounted on the screening machine body 42. The screening machine hopper 43 is connected to the discharge end of the belt conveyor 30. The screening machine body 42 is used to vibrate and automatically separate the insulating sand entering it into layers according to particle size, and then feeds the separated insulating sand into the material frame conveyor 50. In a specific embodiment of this optional solution, the screening machine body 42 is a conventional device on the market used to automatically separate objects into layers according to particle size through vibration. As in this invention, the insulating sand flows into the screening machine hopper 43 under gravity, and the screening machine body 42 separates the insulating sand into two particle sizes, which then flow into the two receiving frames 51 of the material frame conveyor 50 respectively. In this invention, the insulating sand can be reused after secondary screening, which is beneficial for saving resources and protecting the environment. The invention includes two screening processes: First, the insulating sand sorting plate 22 of the material sorting device 20 has sorting holes of a certain size to separate the insulating sand from large particles of impurities. Second, the insulating sand is conveyed by the belt conveyor 30 to the vibrating screen 40 for further screening, separating out small particles that do not meet the requirements. After secondary screening, the insulating sand can be reused, which is beneficial for saving resources and protecting the environment.

[0042] In this optional solution, such as Figure 3 and Figure 5 As shown, the material frame conveying device 50 also includes a material frame conveyor frame 52 vertically supported on a ground foundation, and a material frame conveying power roller 53 mounted on the top of the material frame conveyor frame 52. The receiving frame 51 is supported on the material frame conveying power roller 53 for being pushed into the discharge lifting system 70 during the rotation of the material frame conveying power roller 53. In a specific embodiment of this optional solution, the material frame conveying power roller 53 has a conventional market structure, including multiple rotating rollers arranged in a rotatable manner at intervals, and a drive mechanism for driving the multiple rotating rollers to move synchronously. During operation, the receiving frame 51 rests on the rotating rollers of the material frame conveying power roller 53. The material frame conveying device 50 of the present invention includes two sets of independently operating material frame conveying power rollers 53 to accommodate two receiving frames 51. When the drive mechanism drives the rotating rollers to rotate, it causes the receiving frame 51 supported on them to translate. Preferably, as shown... Figure 3 As shown, the material frame conveying device 50 of the present invention also includes a monitoring camera 54, which is used to monitor the situation of thermal insulation sand falling into the receiving frame 51 in real time. After the receiving frame 51 is full of thermal insulation sand, the material frame conveying power roller 53 conveys it to the discharge lifting system 70.

[0043] Optionally, such as Figure 5 and Figure 6As shown, the discharge lifting system 70 includes a lifting system frame 71 vertically supported on a ground foundation, a lifting platform frame 72 slidably mounted on the lifting system frame 71, a lifting system power roller 73 fixed to the lifting platform frame 72, and elevators 74 located at the upper and lower ends of the lifting system frame 71. The lifting system power roller 73 is used to push the receiving frame 51 located on it to the workshop floor during rotation. The elevators 74 are fixed to the lifting platform frame 72 to pull the lifting platform frame 72 up and down during operation.

[0044] In this optional solution, the lifting platform frame 72 is connected to the lifting system frame 71 via rollers or slide rails; the lifting system power roller 73 is a conventional structure, including multiple rotating rollers arranged at intervals and rotating in sequence, and a drive mechanism for driving the multiple rotating rollers to move synchronously. The receiving frame 51 is conveyed to the lifting system power roller 73 by the material frame conveying power roller 53, and the lifting system power roller 73 can realize the lateral movement of the receiving frame 51. The elevator 74 includes winding rods 741 respectively arranged at the upper and lower ends of the lifting system frame 71 and rotating thereon, multiple drive chains 742 wound between two winding rods 741, a lifting power motor 743 arranged at the lower end of the lifting system frame 71, and a chain drive structure 744 connecting the lifting power motor 743 and the corresponding winding rods 741. The multiple drive chains 742 are respectively fixed to the lifting platform frame 72. During operation, the lifting power unit 743 drives the chain transmission structure 744 to operate. The chain transmission structure 744 then drives the winding rod 741 to rotate, thereby pulling the drive chain 742 up and down. The drive chain 742 then drives the upper winding rod 741 to rotate, thus realizing the up and down movement of the drive chain 742, which in turn drives the lifting platform frame 72 to slide up and down. The lifting platform frame 72 lifts the lifting system power roller 73 and the receiving frame 51 filled with insulating sand to the highest position according to the instructions. Then, the receiving frame 51 is manually hoisted to the storage area.

The suction generated by the dust collector body 81 draws dust into the dust removal branch pipes 84, and the dust enters the dust removal main pipe 82 along the dust removal branch pipes 84, and finally enters the dust collector body 81. The dust-treated air is discharged through a high-altitude duct.
