Description

Technical Field

[0001] This utility model belongs to the field of briquetting machine technology, and in particular relates to a briquetting machine for fluorite powder processing. Background Technology

[0002] Fluorite often forms massive or granular aggregates, or cubic and octahedral single crystals. Fluorite is an alkaline diluent. Because fluorite crystals are generally large, very large fluorite luminous beads can be found. Fluorite has a wide range of uses, including fluorite spheres made from fluorite powder. The processing of fluorite spheres requires a briquetting machine.

[0003] For example, a fluorite powder briquetting machine according to patent application number CN202121844526.X has a conveyor belt at the lower end of the inner wall of the briquetting machine shell, a discharge port on one side of the briquetting machine shell located on the side of the conveyor belt, a feeding port at the upper end of the briquetting machine shell, and a briquetting machine cavity inside the briquetting machine shell. A mixing unit is located between the feeding port and the briquetting machine cavity. This arrangement allows larger fluorite powder impurities to be mixed and shaped into fluorite powder of appropriate size. The briquetting machine cavity is equipped with a first briquetting roller and a second briquetting roller, which are arranged with their sides intersecting. A ventilation cavity is provided on one side of the inner wall of the briquetting machine shell. One end of the ventilation cavity is fixedly connected to an exhaust fan unit and connected to the upper end of the discharge port. This arrangement allows the exhaust fan to absorb fluorite powder dust at the outlet. The other end of the ventilation cavity is connected to the upper part of the briquetting machine cavity, sucking in the fluorite powder and causing it to fall into the two sets of briquetting rollers, thus enabling the recycling of fluorite powder dust.

[0004] Existing technology, through the installation of mixing units and exhaust units, can mix fluorite powder and treat its dust, but there are still some shortcomings in its overall use:

[0005] First, when fluorite powder raw materials are briquetting, a certain level of humidity needs to be maintained and an appropriate amount of binder needs to be added. If the operation is not done properly, the moisture content in the raw materials will be too high, or the binder will be used improperly, causing the shaped spheres to stick in the trough, making it difficult to discharge and affecting the subsequent normal operation.

[0006] Secondly, during the ball pressing process, raw material debris will adhere to the inside of the ball groove and the surface of the ball pressing roller. If it is not removed, the debris adhering to the ball groove will come into contact with the old material during the second ball pressing, causing cracks or shape defects in the formed spherical material. At the same time, when a lot of debris adheres to the roller surface, it will affect the normal cooperation between the two rollers and seriously affect the product quality.

[0007] Finally, due to the gaps between the ball grooves, when the pressed spherical material is fed out, the unpressed material and the spherical material are fed out at the same time, and the two are mixed together. Subsequent processing is time-consuming and labor-intensive, reducing work efficiency. Utility Model Content

[0008] This invention aims to overcome the technical problems of insufficient fluorite powder raw material preparation in the prior art, which affects the subsequent feeding process, and the failure to remove debris from the briquetting roller, which seriously affects product quality. In addition, it also solves the technical problem of spherical material and raw material mixing together during feeding, which makes subsequent processing more troublesome. This invention provides a briquetting machine for fluorite powder processing.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a briquetting machine for fluorite powder processing, comprising a base, a housing fixedly installed inside the base, two sets of symmetrically arranged rotating shafts rotatably installed inside the housing, rollers fixedly installed between the two rotating shafts in each set, multiple corresponding ball grooves opened on the surface of the rollers, a top rod slidably installed inside the ball grooves, a counterweight fixedly installed at the end of the top rod away from the ball groove, the inside of the rollers being hollow, a triangular air cavity being provided inside the rollers, and multiple air holes corresponding to the counterweights being opened on the short side of the air cavity.

[0010] Optionally, a fixed rod passes through the inside of the rotating shaft and is rotatably engaged; the air chamber is fixedly connected to the fixed rod; and a conduit is connected to the outer end of the fixed rod.

[0011] Optionally, a motor is fixedly installed on one side of the housing, and a meshing gear is fixedly installed on the outer end of the shaft that passes through the front surface of the housing. A transmission component is provided between the output end of the motor and one of the gears.

[0012] Optionally, a fixing plate parallel to the roller body is fixedly installed on both sides of the inner cavity of the box body, and a brush that abuts against the roller body and the ball groove is fixedly installed on the opposite side of the fixing plate.

[0013] Optionally, two filter plates are rotatably mounted on the inner cavity of the housing, arranged in an alternating manner.

[0014] Optionally, a spring is fixedly installed on the lower surface of the filter plate near the inner cavity of the housing.

[0015] Optionally, hot air blowers are fixedly installed on both sides of the housing, and an air outlet communicating with the hot air blowers is opened in the inner cavity of the housing. The air outlet is in the same direction as the inclination of the filter plate.

[0016] Optionally, a discharge port is provided on one side of the box, one of the filter plates passes through the interior of the discharge port, and a discharge outlet is provided at the bottom of the box.

[0017] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0018] (1) This utility model, through the setting of top rod, counterweight, air chamber, air hole and brush, can quickly push the spherical material out of the ball groove after the raw material is pressed into a spherical shape, and quickly complete the feeding. It avoids the spherical material from being too wet or the adhesive being used improperly, which would stick to the ball groove and improve the feeding effect. At the same time, it can automatically clean the ball pressing roller after feeding, which improves the quality of the spherical material.

[0019] (2) This utility model, through the setting of filter plate, spring, hot air blower and air outlet, can fully separate spherical material and raw material fragments after drying, thereby improving the quality of finished product. At the same time, it can collect the fragments for secondary recycling and reduce the cost of use. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1:

[0031] refer to Figure 1 A briquetting machine for fluorite powder processing includes a base 10, with a support leg 11 fixedly installed on the lower surface of the base 10. A box 12 is fixedly installed inside the base 10, and a feed inlet 13 is connected to the top of the box 12. In use, the raw material is fed from the feed inlet 13 and enters the box 12 to be briquetting and forming.

[0032] Further reference Figure 1 , Figure 3 and Figure 4 Inside the housing 12, two sets of symmetrically arranged rotating shafts 14 are rotatably mounted. Between each set of two rotating shafts 14, rollers 15 are fixedly mounted and fitted together. The surface of each roller 15 has multiple corresponding ball grooves 16. The outer ends of the two sets of rotating shafts 14 penetrate the housing 12. Gears 19 are fixedly mounted on the outer ends of the rotating shafts 14 that penetrate the front surface of the housing 12. A motor 17 is fixedly mounted on one side of the housing 12. A transmission assembly 18 is provided between the output end of the motor 17 and one of the gears 19. The transmission assembly 18 includes synchronous pulleys fixedly mounted to the output end of the motor 17 and the surface of the gear 19, respectively. The two synchronous pulleys are connected by a synchronous belt. When raw materials enter the housing 12... Then, the material falls onto the upper surface of the two rollers 15. The motor 17 drives one of the gears 19 to rotate through the transmission assembly 18, which in turn drives the other meshing gear 19 to rotate in the opposite direction, causing the two rollers 15 to rotate relative to each other. This presses the material into the ball groove 16, and the two ball grooves 16 fit together to press the material into a spherical shape. As the rollers 15 continue to rotate, the two ball grooves 16 separate. When the spherical material is at the bottom, it is automatically unloaded by its own weight. It should be noted that in order to ensure the stable transmission of the synchronous belt structure, a tensioning wheel structure is set between the two synchronous pulleys in actual production to ensure stable transmission. However, the tensioning wheel structure is a conventional existing technology, so this solution will not be drawn or shown in detail.

[0033] Further reference Figure 5 and Figure 6The roller body 15 is hollow inside, and a push rod 20 is slidably installed inside each ball groove 16. A counterweight 21 is fixedly installed at the end of the push rod 20 away from the ball groove 16. During feeding, the counterweight 21 can pull the push rod 20 to the bottom of the ball groove 16. At this time, the roller body 15 rotates to the relative position, pressing the raw material into a spherical shape through the two ball grooves 16. The roller body 15 continues to drive, completing the unloading. If the raw material has high moisture content or the binder is used improperly, the spherical material will stick to the inside of the ball groove 16 and be difficult to discharge. In this case, when the counterweight 21 is above, it presses the push rod 20 with gravity, causing the push rod 20 to slide downward inside the ball groove 16, thereby pushing out the spherical material and completing the unloading work. This effectively avoids the sticking phenomenon and improves the use effect.

[0034] Further reference Figure 2 , Figure 6 and Figure 7 Two rotating shafts 14 are connected to a fixed rod 22 at their ends away from the gear 19, and are rotated together. A triangular air chamber 23 is fixedly installed at the end of the fixed rod 22 inside the roller body 15. The short side of the air chamber 23 has multiple air holes 24 corresponding to the ball groove 16. Two air pumps 25 are fixedly installed on the back side of the box body 12. The top air outlet of the air pump 25 is connected to a conduit 26. The conduit 26 passes through the inside of the fixed rod 22 and is connected to the air chamber 23. When feeding, if the viscosity of the spherical material is high and the weight of the counterweight 21 cannot complete the feeding, the feeding work cannot be guaranteed. The air pump 25 can be used to pressurize the air chamber 23 through the conduit 26 and then discharge it through the air holes 24. This airflow is directed towards the counterweight 21, applying pressure to the counterweight 21, thereby pushing the top rod 20 downward to complete the feeding and further ensuring the normal operation of the feeding work.

[0035] Further reference Figure 5 and Figure 6 The inner cavity of the housing 12 is fixedly installed with fixed plates 27 parallel to the ball groove 16 on both sides. The opposite surfaces of the fixed plates 27 are fixedly installed with brushes 28. After the material is fed, the two rollers 15 rotate in opposite directions. At this time, the brushes 28 abut against the surface of the rollers 15 and the inside of the ball groove 16. When the rollers 15 rotate, they can remove the debris adhering to the surface of the rollers 15 and the inside of the ball groove 16, preventing the debris from adhering to the inside of the ball groove 16 and avoiding cracks on the surface of the spherical material when pressing the ball again. At the same time, the material adhering to the surface of the rollers 15 is also removed to prevent the material adhering to the surface of the rollers 15 from affecting the fit between the two rollers 15, causing errors when the two ball grooves 16 are closed, and affecting the quality of the finished product.

[0036] Example 2:

[0037] A briquetting machine for fluorite powder processing, further illustrated in Example 1, is provided for reference. Figure 4 and Figure 8 Two staggered filter plates 29 are rotatably installed on both sides of the inner cavity of the housing 12 and below the roller 15. A spring 30 is fixedly installed on the lower surface of the filter plate 29 near the inner cavity of the housing 12. In the above scheme, both spherical material and debris fall onto the surface of the lower filter plate 29. When the material falls onto the surface of the filter plate 29 by gravity, the spring 30 causes the filter plate 29 to vibrate up and down, separating the debris and spherical material. The spherical material rolls down, and the debris falls down after passing through the filter holes of the filter plate 29. The filter screen of the debris filter plate 29 is made of rubber material to prevent the spherical material from being dispersed after being impacted, thus improving the performance.

[0038] Further reference Figure 4 and Figure 8 Hot air blowers 31 are fixedly installed on both sides of the housing 12. An air outlet 32 ​​communicating with the hot air blower 31 is opened inside the housing 12, and the air outlet 32 ​​is in the same direction of inclination as the filter plate 29. When the material falls onto the surface of the filter plate 29, the hot air blower 31 blows hot air onto the surface of the filter plate 29 through the air outlet 32, which can dry the spherical material and debris, so that the spherical material can be quickly shaped, and at the same time remove the moisture of the debris, reducing the occurrence of debris sticking to the filter holes of the filter plate 29, thus avoiding clogging. Secondly, the inclined air blowing can accelerate the rolling speed of the spherical material, preventing the spherical material from getting stuck in the filter holes of the filter plate 29, which greatly improves the use effect.

[0039] Further reference Figure 1 and Figure 4 The box 12 has a discharge port 33 on one side, and a filter plate 29 is inserted through the discharge port 33. The box 12 has a discharge port 34 at the bottom. After two screenings, the spherical material and the debris are fully separated. The spherical material is discharged from the discharge port 33 and the debris is discharged from the discharge port 34. The debris can be recycled and reused, saving costs.

[0040] Finally, it should be noted that the connection and fixing of each part of the fluorite powder briquetting machine of this utility model can be achieved by conventional mechanical connection structure, and the control system and connection method required between multiple electrical components and drive components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as the beneficial effect or the specific actions in the above work can be achieved, it can be implemented.

[0041] The motor 17, air pump 25, hot air blower 31, etc. of the briquetting machine for fluorite powder processing in this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without the need for creative labor by technical personnel in this field.
