Description

Technical Field

[0001] The utility model relates to the technical field of cold pressing agglomeration, in particular to a pressurized ball press machine used for cold pressing agglomeration. Background Art

[0002] As the food of industry, steel plays a vital role in the rapid development of industrialization, but it also brings a lot of powdery wastes such as smoke, slag, sludge, iron oxide scale and non-ferrous metal smelting intermediate return materials. With the improvement of public environmental awareness, the treatment of these wastes has received widespread attention from all walks of life. In view of the fine particle size of these powders, direct recycling into the furnace is likely to cause the furnace condition to deteriorate. In addition, the cold pressing agglomeration equipment has the advantages of simple structure, low cost, and effective reduction of carbon dioxide emissions. Therefore, the cold pressing agglomeration technology has been widely used in the field of solid waste treatment in the metallurgical industry.

[0003] Cold pressing agglomeration technology is to add a binder to consolidate the powder at room temperature, so that the pressed pellets have a certain mechanical strength. In order to make the pellets have a certain mechanical strength, the ball press has become one of the key equipment of cold pressing agglomeration technology, and the ball press has been widely used in metallurgy, coal, mining and other industries. At present, most ball presses use double-roller ball presses. The mixed material is fed into the double-roller ball press assembly through a feeding device. There are ball sockets that meet the requirements on the rollers. The mixed material is pressed into pellets under the action of pressure, and then falls on the transportation equipment for discharge.

[0004] At present, the cold-pressed briquetting process still has certain shortcomings. The briquetting process mainly uses a double-roll briquetting machine for briquetting. Considering the service life of the equipment, objective conditions and other factors, the pressure applied between the rollers of the briquetting machine is limited. One briquetting may result in insufficient briquetting strength, resulting in low compressive strength of the finished product, high return rate, low production efficiency and other problems. If two double-roll briquetting machines are connected in series, in order to avoid the binder solidification caused by too long a time after one briquetting, it is necessary to ensure that the two devices are close to each other, which not only increases the floor space but also increases the difficulty of equipment maintenance.

[0038] The details of the present invention can be more clearly understood by combining the accompanying drawings with the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used for the purpose of explaining the present invention and cannot be understood as limiting the present invention in any way. Under the guidance of the present invention, technicians can conceive of any possible variations based on the present invention, which should be considered to belong to the scope of the present invention.

[0039] In order to solve the problems of insufficient pressing strength, high return rate and low production efficiency in one-time pressing of the cold pressing agglomeration and briquetting process using a double-roller briquetting machine alone, a pressurized briquetting machine for cold pressing agglomeration is proposed in this application. Figure 1 This is an overall schematic diagram of a pressurized ball press machine for cold pressing and agglomeration in an embodiment of the utility model. Figure 2 FIG. 1 is a partial cross-sectional schematic diagram of a pressurized ball press machine for cold pressing and agglomeration in an embodiment of the utility model, as shown in FIG. Figure 1 and Figure 2 As shown, the pressurized ball press machine for cold pressing agglomeration may include: a shell assembly 1, a first pair of rollers 2, a material collecting and feeding mechanism 3 and a second pair of rollers 4.

[0040] A feed port 11 and a discharge port 12 are formed on the shell assembly 1. The feed port 11 is used to input materials, such as granular materials that have not been pressed. The discharge port 12 is used to discharge finished materials that have been pressed into a spherical shape. The shell assembly 1 may include a vertically arranged feed barrel 13 and an outer barrel 14 located below the feed barrel 13. The feed barrel 13 may be connected to the opening of the upper end surface of the feed barrel 13. The feed port 11 is formed at the upper end of the feed barrel 13, and the discharge port 12 is formed at the lower end of the outer barrel 14. The first outlet 134 of the feed barrel 13 can transport the material in the feed barrel 13 to the outer barrel 14.

[0041] The first pair of rollers 2, the material collecting and feeding mechanism 3 and the second pair of rollers 4 are sequentially arranged in the outer cylinder 14 from top to bottom. The surfaces of the two rollers in the first pair of rollers 2 have a ball-and-socket structure. The first outlet 134 of the feeding cylinder 13 is located above the first pair of rollers 2 so that the granular material entering the feeding port 11 flows out through the first outlet 134 of the feeding cylinder 13 and then passes between the two rollers of the first pair of rollers 2 to be pressed into a spherical shape.

[0042] The extension direction of the first outlet 134 of the feed drum 13 is the same as the extension direction of the first pair of rollers 2. In this way, the material in the feed drum 13 can fall downward in a straight line and basically enter between the two rollers of the first pair of rollers 2, thereby improving the pressing efficiency of the first pair of rollers 2 and preventing the material falling downward from not entering between the two rollers of the first pair of rollers 2 and not being pressed into a spherical shape.

[0043] Furthermore, both ends of the first outlet 134 of the feeding barrel 13 extend to the inner side wall of the feeding barrel 13 .

[0044] Since there is a gap between the first pair of rollers 2 and the inner wall of the outer cylinder 14, in order to prevent the granular material flowing out of the first outlet 134 of the feed cylinder 13 from entering the material and the feeding mechanism through the gap between the first pair of rollers 2 and the inner wall of the feed cylinder 13, a first baffle 133 is provided at the first outlet 134 of the feed cylinder 13 to make the material output from the first outlet 134 of the feed cylinder 13 move toward between the two rollers of the second pair of rollers 4.

[0045] The collecting and feeding mechanism 3 is used to collect the spherical materials produced by the first pair of rollers 2. The second outlet 32 ​​of the collecting and feeding mechanism 3 corresponds to the second pair of rollers 4. The surfaces of the two rollers in the second pair of rollers 4 have a spherical socket structure. The size of the spherical socket structure of the second pair of rollers 4 is larger than that of the first pair of rollers 2. Through the above structure, the material that has been pressed into a spherical shape with a relatively small particle size is transported to the finished product that is pressed into a spherical shape with a relatively large particle size between the two rollers of the second pair of rollers 4. The discharge port 12 is used to discharge the spherical finished product pressed by the second pair of rollers 4.

[0046] As a feasible method, the diameters of the rollers in the first pair of rollers 2 and the rollers in the second pair of rollers 4 may be the same, so as to make the outer cylinder 14 miniaturized and uniform in upper and lower dimensions.

[0047] As feasible, the feed barrel 13 may have a side wall and a bottom wall, and a first outlet 134 of the feed barrel 13 in a long strip shape is formed on the bottom wall of the feed barrel 13. The structure of the feed barrel 13 is similar to that of the material collecting and feeding mechanism 3, and can be referred to Figure 3. The feed barrel 13 may further include: a first stirring mechanism 132 disposed in the feed barrel 13. The first stirring mechanism 132 includes: a first rotating shaft; a first stirring component connected to the first rotating shaft, at least part of the first stirring component extending along the radial direction of the feed barrel 13 and close to the bottom wall of the feed barrel 13. The first rotating shaft can drive the first stirring component to rotate, so that the first stirring component continuously pushes the material in the feed barrel 13 into the first outlet 134 of the feed barrel 13 in a straight line, preventing the material from accumulating in the feed barrel 13, ensuring the uniformity and efficiency of the material output, and facilitating the uniformity of the finished product during one-time ball pressing.

[0048] Further, both ends of the first stirring assembly extend to the inner side wall of the feed barrel 13, thereby ensuring that there is no dead angle in stirring. The first stirring assembly may include a first cross bar connected to the first rotating shaft, a first vertical bar connected to the end of the first cross bar, and a first oblique bar connecting the upper end of the first vertical bar and the first cross bar. The first vertical bar may be close to the inner side wall of the feed barrel 13 to avoid dead angles.

[0049] As feasible, Figure 2 As shown, a first baffle 133 is provided at the first outlet 134 of the feed barrel 13, so that the material output from the first outlet 134 of the feed barrel 13 moves toward between the two rollers of the first pair of rollers 2. The first baffle 133 can be two pieces, which are arranged opposite to each other. The extension direction of the first baffle 133 is the same as the extension direction of the first outlet 134 of the feed barrel 13.

[0050] As feasible, Figure 2 As shown, the inlet of the collecting and feeding mechanism 3 is connected to the inner wall of the outer cylinder 14 through the guide plate 16. The guide plate 16 allows the material collected on the guide plate 16 to slide to the inlet of the collecting and feeding mechanism 3, avoiding it from being discharged directly from the discharge port 12 without being pressed.

[0051] In one possible implementation, Figure 3 Schematic diagram of the three-dimensional structure of the material collection and feeding mechanism in the embodiment of the utility model, as shown in FIG. Figure 3 As shown, the material collecting and feeding mechanism 3 may include: a cylinder 31 having a side wall and a bottom wall, and a second outlet 32 ​​of the material collecting and feeding mechanism 3 in the shape of a long strip is formed on the bottom wall. The extension direction of the second outlet 32 ​​of the material collecting and feeding mechanism 3 is the same as the extension direction of the second pair of rollers 4, so that the spherical materials in the material collecting and feeding mechanism 3 fall downward in a straight line and basically enter between the two rollers in the second pair of rollers 4, thereby improving the pressing efficiency of the second pair of rollers 4 and preventing the materials falling downward from not entering between the two rollers in the second pair of rollers 4 and not being pressed into a spherical shape.

[0052] Furthermore, both ends of the second outlet 32 ​​of the material collecting and feeding mechanism 3 extend to the inner side wall of the cylinder 31 .

[0053] like Figure 3 As shown, the material collection and feeding mechanism 3 may include: a second stirring mechanism 33 disposed in the barrel 31, the second stirring mechanism 33 including: a second rotating shaft 331; a second stirring assembly 332 connected to the second rotating shaft 331, at least part of the second stirring assembly 332 extending along the radial direction of the barrel 31 and close to the bottom wall of the barrel 31. The second rotating shaft 331 can drive the second stirring assembly 332 to rotate, so that the second stirring assembly 332 continuously pushes the spherical material in the barrel 31 into the second outlet 32 ​​of the material collection and feeding mechanism 3 in a straight line, preventing the material from accumulating in the material collection and feeding mechanism 3, ensuring the uniformity and efficiency of the material output, and facilitating the uniformity of the finished product during the secondary ball pressing.

[0054] The first rotating shaft and the second rotating shaft 331 are respectively connected to the motor in driving connection, so as to drive the first rotating shaft and the second rotating shaft 331 to rotate.

[0055] Further, such as Figure 3 As shown, both ends of the second stirring assembly 332 extend to the inner side wall of the cylinder 31, thereby ensuring that there is no dead angle in stirring. The second stirring assembly 332 may include a second cross bar 3321 connected to the second rotating shaft 331, a second vertical bar 3322 connected to the end of the second cross bar 3321, and a second oblique bar 3323 connecting the upper end of the second vertical bar 3322 and the second cross bar 3321. The second vertical bar 3322 may be close to the inner side wall of the cylinder 31 to avoid dead angles.

[0056] As feasible, Figure 2 As shown, a second baffle 34 may be provided at the second outlet 32 ​​of the material collecting and feeding mechanism 3, so that the spherical materials outputted from the second outlet 32 ​​of the material collecting and feeding mechanism 3 are all moved toward between the two rollers of the second pair of rollers 4. The second baffle 34 may be two pieces, which are arranged opposite to each other. The extension direction of the second baffle 34 is the same as the extension direction of the second outlet 32 ​​of the material collecting and feeding mechanism 3.

[0057] As feasible, Figure 2 As shown, the pressurized ball press machine for cold pressing can include: a push rod 5 that can move along the radial direction of the cylinder 31, and the push rod 5 can be connected to the second baffle 34 to control the discharge amount of the second outlet 32 ​​of the collection and feeding mechanism 3.

[0058] The pressurized ball press machine for cold pressing agglomeration may include: a driving unit for driving the push rod 5 to move in the radial direction of the cylinder 31. When the discharge amount of the spherical material output from the second outlet 32 ​​of the material collecting and feeding mechanism 3 is reduced, the driving unit is controlled to move the push rod 5 in the radial direction of the cylinder 31, the second baffle 34 approaches the other second baffle 34, the interval between the two second baffles 34 is reduced, and the discharge amount of the second outlet 32 ​​of the material collecting and feeding mechanism 3 is reduced.

[0059] As feasible, Figure 2 As shown, the pressurized briquetting machine for cold pressing can include: a second material level monitoring device 35 for monitoring the height of the material level in the material collection and feeding mechanism 3. The second material level monitoring device 35 can be arranged in the cylinder 31.

[0060] like Figure 1 and Figure 2 As shown, the pressurized ball press machine for cold pressing agglomeration may include: a control unit 6, a second material level monitoring device 35, and a driving unit electrically connected to the control unit 6. The driving unit is used to control the driving unit according to the height of the material level in the aggregate and feeding mechanism 3 monitored by the second material level monitoring device 35. When the material level in the aggregate and feeding mechanism 3 reaches a certain height, the discharge speed of the aggregate and feeding mechanism 3 or the feeding speed of the pressurized ball press machine for cold pressing agglomeration can be immediately adjusted through the above structure to prevent the material level from being too high or too low, control the material level within a certain range, and improve the stability of product quality.

[0061] As feasible, Figure 1 and Figure 2 As shown, the pressurized ball press machine for cold pressing and agglomeration may include: a first material level monitoring device 131 for monitoring the height of the material level in the feed barrel 13. The first material level monitoring device 131 may be arranged in the feed barrel 13. The first material level monitoring device 131 is electrically connected to the control unit 6. The driving unit is used to control the driving unit according to the height of the material level in the feed barrel 13 monitored by the first material level monitoring device 131. When the feed barrel 13 reaches a certain height, the feed speed can be adjusted immediately through the above structure to prevent the material level in the feed barrel 13 from being too high or too low, control the material level within a certain range, and improve the stability of product quality.

[0062] As feasible, Figure 1 As shown, an inspection door 15 may be provided on the side wall of the outer cylinder 14 to facilitate inspection of the first pair of rollers 2 and the second pair of rollers 4.

[0063] The pressurized briquetting machine for cold pressing may include a transfer mechanism 7, part of which is located directly below the discharge port 12 to rotate the spherical material dropped from the discharge port 12. For example, the transfer mechanism 7 may be a device such as a belt conveyor.

[0064] The pressurized ball press machine for cold pressing agglomeration in the present application first presses the material into a relatively small sphere by the first pair of rollers 2, thereby first improving a certain mechanical strength, and then the relatively small sphere is pressed into a relatively large sphere by the second pair of rollers 4. The mechanical strength of the finished pellets can be effectively improved, and the success rate of pressing the relatively large sphere is also greatly improved, reducing the return rate, thereby avoiding the low compressive strength of the finished product, the high return rate, the low production efficiency, and the situation of being broken due to the large impact force in the subsequent transportation and production process. The pressurized ball press machine for cold pressing agglomeration in the present application adopts the method of setting two pairs of rollers up and down, and the entire secondary pressing process of the material can be realized by gravity. In addition, a collection and feeding mechanism 3 is set between the two pairs of rollers, which can prevent the accumulation of materials while also ensuring the uniformity of the feeding, thereby ensuring the uniformity of the ball. Finally, a first stirring mechanism 132 is also provided in the feed barrel 13, which can prevent material accumulation while ensuring the uniformity of the feed, thereby ensuring the uniformity of the ball formation.
