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. Utility Model Content

[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] The housing assembly 1 is formed with a feed port 11 and a discharge port 12. 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 materials that have been pressed into a spherical shape.

[0041] The first pair of rollers 2, the material collecting and feeding mechanism 3 and the second pair of rollers 4 are arranged in sequence in the housing assembly 1 from top to bottom.

[0042] The surface of one roller in the first pair of rollers 2 has a spherical structure. The surface of the other roller in the first pair of rollers 2 does not have a spherical structure. The feed port 11 is located above the first pair of rollers 2 so that part of the granular material entering the feed port 11 is pressed into a hemispherical shape through the first pair of rollers 2.

[0043] Part of the material entering the feed port 11 enters the feed and the feed mechanism without passing through the first pair of rollers 2. In other words, there is a gap between the first pair of rollers 2 and the inner side wall of the housing assembly 1, so that part of the material entering the feed port 11 enters the feed and the feed mechanism through the gap between the first pair of rollers 2 and the housing assembly 1.

[0044] Specifically, the housing assembly 1 includes a vertically arranged feed cylinder 13, the first pair of rollers 2 is arranged in the feed cylinder 13, and the upper end of the feed cylinder 13 forms a feed port 11. There is a gap between the first pair of rollers 2 and the inner side wall of the feed cylinder 13, so that part of the material entering the feed port 11 passes through the gap between the first pair of rollers 2 and the inner side wall of the feed cylinder 13 and enters the material and the feeding mechanism.

[0045] The collecting and feeding mechanism 3 is used to collect hemispherical materials and granular materials. The 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 ball-socket structure. Through the above structure, the hemispherical materials and granular materials are transported to the space between the two rollers of the second pair of rollers 4 and pressed into a spherical shape. The discharge port 12 is used to discharge the spherical materials pressed out by the second pair of rollers 4.

[0046] As is feasible, the first pair of rollers 2 and the second pair of rollers 4 have different specifications. The diameter of the rollers in the second pair of rollers 4 is greater than the diameter of the rollers in the first pair of rollers 2.

[0047] For example, the inlet of the material collecting and feeding mechanism 3 is connected to or abutted against the lower end of the feeding barrel 13, so that the inlet of the material collecting and feeding mechanism 3 receives the material pressed into a hemispherical shape and the granular material that has not been pressed and discharged from the feeding barrel 13.

[0048] For example, Figure 2 As shown, the first pair of rollers 2 is arranged below the feed cylinder 13, the housing assembly 1 includes a vertically arranged outer cylinder 14, and the periphery of the inlet of the material collection and feeding mechanism 3 is connected to the inner side wall of the outer cylinder 14 through the guide plate 16. The guide plate 16 allows the granular material collected on the guide plate 16 to slide to the inlet of the material collection and feeding mechanism 3.

[0049] 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 long strip-shaped outlet 32 ​​of the material collecting and feeding mechanism 3 is formed on the bottom wall. The extension direction of the 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 hemispherical materials and granular 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.

[0050] Furthermore, both ends of the outlet 32 ​​of the material collecting and feeding mechanism 3 extend to the inner side wall of the cylinder 31 .

[0051] like Figure 3As shown, the material collection and feeding mechanism 3 may include: a stirring mechanism 33 disposed in the barrel 31, the stirring mechanism 33 including: a rotating shaft 331; a stirring assembly 332 connected to the rotating shaft 331, at least part of the stirring assembly 332 extending along the radial direction of the barrel 31 and close to the bottom wall of the barrel 31. The rotating shaft 331 can drive the stirring assembly 332 to rotate, so that the stirring assembly 332 mixes the hemispherical material and the granular material in the barrel 31, and continuously pushes them into the 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.

[0052] Further, such as Figure 3 As shown, both ends of the stirring assembly 332 extend to the inner side wall of the cylinder 31, thereby ensuring that there is no dead angle in stirring. The stirring assembly 332 may include a cross bar 3321 connected to the rotating shaft 331, a vertical bar 3322 connected to the end of the cross bar 3321, and an inclined bar 3323 connecting the upper end of the vertical bar 3322 and the cross bar 3321. The vertical bar 3322 may be close to the inner side wall of the cylinder 31 to avoid dead angles.

[0053] As feasible, Figure 2 As shown, a baffle 34 may be provided at the outlet 32 ​​of the material collecting and feeding mechanism 3, so that the hemispherical material and the granular material outputted from the outlet 32 ​​of the material collecting and feeding mechanism 3 are moved toward between the two rollers of the second pair of rollers 4. The baffle 34 may be two pieces, which are arranged opposite to each other. The extending direction of the baffle 34 is the same as the extending direction of the outlet 32 ​​of the material collecting and feeding mechanism 3.

[0054] 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 baffle 34 to control the discharge amount of the outlet 32 ​​of the aggregate and feeding mechanism 3.

[0055] The pressurized ball press machine for cold pressing can include: a driving unit for driving the push rod 5 to move along the radial direction of the cylinder 31. When the discharge amount of the hemispherical material and the granular material outputted from the outlet 32 ​​of the material collecting and feeding mechanism 3 is reduced, the driving unit is controlled to move the push rod 5 along the radial direction of the cylinder 31, the baffle 34 approaches the other baffle 34, the interval between the two baffles 34 is reduced, and the discharge amount of the outlet 32 ​​of the material collecting and feeding mechanism 3 is reduced.

[0056] 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.

[0057] 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.

[0058] As feasible, 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.

[0059] As feasible, the housing assembly 1 may include a vertically arranged outer cylinder 14, and the material collecting and feeding mechanism 3 and part of the feeding cylinder 13 are arranged in the outer cylinder 14. The second pair of rollers 4 are arranged in the outer cylinder 14 outside the feeding cylinder 13. Further, the discharge port 12 is located at the bottom of the outer cylinder 14. An inspection door 15 may be provided on the side wall of the outer cylinder 14 to facilitate the inspection of the first pair of rollers 2 and the second pair of rollers 4.

[0060] like Figure 1 As shown, the pressurized briquetting machine for cold pressing can include: a transfer mechanism 7, part of which is located directly below the discharge port 12 to transfer the spherical material falling from the discharge port 12. For example, the transfer mechanism 7 can be a device such as a belt conveyor.

[0061] The pressurized ball press machine for cold pressing agglomeration in the present application first presses the material into a hemispherical shape through the first pair of rollers 2, and then presses the hemispherical material and the granular material into spherical finished pellets, which can effectively improve the mechanical strength of the finished pellets and reduce 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. The material enters the first pair of rollers 2 from the feed port during the entire secondary pressing process, comes out of the first pair of rollers 2 to enter the collection and feeding mechanism 3, and enters the second pair of rollers 4 by the collection and feeding mechanism 3. The movement process can be realized by gravity. In addition, the 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 feed, thereby ensuring the uniformity of the ball.
