Description

Technical Field

[0001] This utility model relates to the technical field of glass microsphere production equipment, and in particular to a collection cylinder for the production of hollow glass microspheres. Background Technology

[0002] Hollow glass microspheres are tiny spherical shells made of silicate glass with a closed cavity structure inside. They are characterized by low density, high specific strength, excellent compressive strength, and chemical stability. The core of their production process lies in rapidly cooling and shaping glass droplets into thin-walled, hollow micron-sized particles using a special melt-spraying technique. During production, due to the extremely small particle size and light weight of the microspheres, a special collection tube is required for efficient collection.

[0003] The patent with publication number CN210207223U mentions a collection cylinder for the production of hollow glass microspheres, including an adsorption cylinder and a shell. The adsorption cylinder is installed inside the shell and is connected to the previous process section through the feed port to receive hollow glass microspheres to be cooled. After entering the adsorption cylinder, the hollow glass microspheres are adsorbed by the charged adsorption cylinder, thus separating the hollow glass microspheres from the airflow. The adsorption cylinder has two layers, and multiple cross-shaped adsorption plates are arranged inside the adsorption cylinder. The adsorption plates are all charged, increasing the adhesion area of ​​the hollow glass microspheres and preventing the hollow glass microspheres from escaping with the airflow. At the same time, the gas flow inside the hollow adsorption plates can play a cooling role, assisting in the cooling of the hollow glass microspheres. This utility model has a reasonable structure, which can not only achieve better cooling effect at a shorter height, but also prevent the product from moving with the airflow and not being collected.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] When the existing collection cylinder for hollow glass microsphere production is in use, the glass microspheres produced above pass through the adsorption plate vertically. This movement causes the feeding speed of the adsorption plate to have an adverse effect on the adsorption efficiency when adsorbing charged glass microspheres. Moreover, the glass microspheres are subject to impact during vertical descent, which can easily lead to damage.

[0006] In addition, although the collecting cylinder can cool the glass microspheres to a certain extent through airflow, its cooling effect is relatively limited and it is difficult to meet higher production requirements.

[0007] Therefore, this solution provides a collection tube for the production of hollow glass microspheres to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a collection cylinder for the production of hollow glass microspheres, so as to solve the problems in the prior art where vertical falling leads to limited adsorption efficiency and air cooling alone leads to limited cooling effect.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] A collection cylinder for producing hollow glass microspheres includes a cylinder body and a discharge electrode. A feed pipe is installed at the top of the cylinder body, and the discharge electrode is embedded inside the feed pipe. A central mechanism is located inside the cylinder body, surrounded by six evenly distributed torsional guide plate mechanisms. An inlet ring pipe and an outlet ring pipe are embedded inside the cylinder body, and a discharge hopper is located at the bottom of the cylinder body. The central mechanism includes a connecting column, a conical guide block, and a guide cover, which are fixedly connected from bottom to top. High-pressure gas pipes are installed inside the connecting column, the conical guide block, and the guide cover. The torsional guide plate mechanisms include a torsional guide plate and two evenly distributed stepped guide plates (one and two) on one side of the torsional guide plate. The torsional guide plate is torn 90 degrees from top to bottom.

[0011] Preferably, one side of the torsion guide plate is fixedly connected to the outer periphery of the connecting column, and the other side of the torsion guide plate is fixedly connected to the inner wall of the cylinder.

[0012] Preferably, the high-pressure air pipe is surrounded by a gas distribution connector pipe, which is located inside the connecting column. The inside of the torsion guide plate is provided with eight evenly distributed air-cooling pipes. One end of the air-cooling pipe is connected to the gas distribution connector pipe, and one side of the air-cooling pipe is provided with evenly arranged air-cooling nozzles, which are located on the back of the torsion guide plate.

[0013] Preferably, the high-pressure air pipe has six guide nozzles connected around its top edge. The guide nozzles are located inside the guide cover and one end is connected to the chamfer at the top edge of the high-pressure air pipe. The nozzle nozzles are parallel to the surface of the cone-shaped guide block.

[0014] Preferably, the outer periphery of the cone guide block is inclined outward at 15 degrees, and part of the cone guide block and guide cover are located inside the feed pipe.

[0015] Preferably, the first and second stepped guide plates are inclined in opposite directions and are staggered, and the inside of the torsion guide plate near the side of the first and second stepped guide plates is provided with a water cooling pipe.

[0016] Preferably, the top end of the water-cooling pipe is provided with a liquid inlet head, and the other end of the water-cooling pipe is provided with a liquid outlet head. The liquid inlet head is connected to the liquid inlet ring pipe, and the liquid outlet head is connected to the liquid outlet ring pipe.

[0017] The beneficial effects of this utility model are:

[0018] I. This utility model, through the cooperation of the central mechanism and the torsion guide plate mechanism, the central mechanism formed by the cone guide block and the guide cover, combined with the 90-degree torsion structure of the torsion guide plate, guides the vertically falling glass microspheres to the adsorption area of ​​the stepped guide plate at one / two, extending their movement path and forming a spiral descent trajectory, thereby increasing the probability of charge adsorption.

[0019] Second, this utility model, through the cooperation of the central mechanism and the torsion guide plate mechanism, adopts a composite cooling scheme of water-cooled pipe and air-cooled pipe. The initial cooling is achieved by injecting circulating coolant through the liquid inlet ring pipe, while the high-pressure air pipe supplies air to the air-cooled nozzle through the air distribution connection pipe to form forced air cooling. The two work together to rapidly reduce the surface temperature of the glass microspheres, breaking through the cooling bottleneck of traditional single air cooling. Attached Figure Description

[0031] Please refer to the following. Figures 1 to 6 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0033] This utility model provides a collection cylinder for the production of hollow glass microspheres, including a cylinder body 1 and a discharge electrode 3. A feed pipe 2 is installed at the top of the cylinder body 1, and the discharge electrode 3 is embedded in the inner side of the feed pipe 2. A central mechanism 4 is provided on the inner side of the cylinder body 1, and six evenly distributed torsional guide plate mechanisms 5 surround the central mechanism 4. An inlet ring pipe 7 and an outlet ring pipe 8 are embedded inside the cylinder body 1, and a discharge hopper 6 is opened at the bottom of the cylinder body 1.

[0034] The central mechanism 4 includes a connecting central column 41, a conical guide block 42, and a guide cover 43, which are fixedly connected from bottom to top. A high-pressure air pipe 44 is provided inside the connecting central column 41, the conical guide block 42, and the guide cover 43.

[0035] The torsion guide plate mechanism 5 includes a torsion guide plate 51 and two stepped guide plates 52 and 53 evenly arranged on one side of the torsion guide plate 51. The torsion guide plate 51 is twisted 90 degrees from top to bottom.

[0036] Both stepped guide plate 52 and stepped guide plate 53 have an adsorption plate embedded inside. The cylinder 1, the discharge electrode 3, and the adsorption plates inside stepped guide plate 52 and stepped guide plate 53 are all existing technologies. The discharge electrode 3 emits a charge that causes the glass microspheres to adhere to the surface of the glass microspheres, thereby allowing the adsorption plates inside stepped guide plate 52 and stepped guide plate 53 to adsorb the glass microspheres.

[0037] In a further embodiment, one side of the torsion guide plate 51 is fixedly connected to the periphery of the connecting column 41, and the other side of the torsion guide plate 51 is fixedly connected to the inner wall of the cylinder 1.

[0038] In this embodiment, the torsion guide plate 51 connects the connecting column 41 and the torsion guide plate 51 so that the connecting column 41 can be located at the center of the cylinder 1.

[0039] In a further embodiment, a gas distribution connector 45 is connected to the periphery of the high-pressure gas pipe 44. The gas distribution connector 45 is located inside the connecting column 41. Eight air-cooled pipes 57 are evenly distributed inside the torsion guide plate 51. One end of the air-cooled pipe 57 is connected to the gas distribution connector 45. An evenly arranged air-cooled nozzle 58 is provided on one side of the air-cooled pipe 57. The air-cooled nozzle 58 is located on the back of the torsion guide plate 51.

[0040] In this embodiment, the air-cooled nozzle 58 is located on the back of the torsion guide plate 51 to air-cool the front end of another torsion guide plate 51. It is also used to force the glass microspheres passing between the two torsion guide plates 51 to the front end of the torsion guide plate 51 to contact the stepped guide plate 1 52 and the stepped guide plate 2 53.

[0041] In a further embodiment, six guide nozzles 46 are connected around the periphery of the top end of the high-pressure air pipe 44. The guide nozzles 46 are located inside the guide cover 43 and one end of them is connected to the chamfer at the top end of the high-pressure air pipe 44. The nozzles of the guide nozzles 46 are parallel to the surface of the cone guide block 42.

[0042] In this embodiment, when high-pressure airflow flows in the high-pressure air pipe 44, it can be guided by the guide nozzle 46 to make a spiral air curtain appear on the surface of the cone guide block 42.

[0043] In a further embodiment, the outer periphery of the cone guide block 42 is tilted outward at a 15-degree angle, and part of the cone guide block 42 and the guide cover 43 are located inside the feed pipe 2.

[0044] In this embodiment, the outer periphery of the cone guide block 42, together with the pneumatic curtain wall on its surface, enables the glass microspheres to be fed in, thus reducing the impact.

[0045] In a further embodiment, the first stepped guide plate 52 and the second stepped guide plate 53 are inclined in opposite directions and are staggered, and a water-cooling pipe 54 is provided inside the torsion guide plate 51 on the side close to the first stepped guide plate 52 and the second stepped guide plate 53.

[0046] In this embodiment, both the stepped guide plate 52 and the stepped guide plate 53 are tilted downwards at a 30-degree angle. After the glass microspheres are guided by the torsion guide plate 51, they will pass above the stepped guide plate 52 and the stepped guide plate 53 and be adsorbed by the adsorption plate inside them.

[0047] In a further embodiment, a liquid inlet head 55 is provided at the top end of the water cooling pipe 54, and a liquid outlet head 56 is provided at the other end of the water cooling pipe 54. The liquid inlet head 55 is connected to the liquid inlet ring pipe 7, and the liquid outlet head 56 is connected to the liquid outlet ring pipe 8.

[0048] In this embodiment, both the inlet ring pipe 7 and the outlet ring pipe 8 have connectors on their outer sides for connecting to an external circulating water pump and cooling tank via hoses, thereby injecting circulating coolant into the interior of the water-cooled pipe 54.

[0049] The working principle of this utility model is as follows:

[0050] When the glass microspheres are produced and fall vertically into the cylinder 1 from the feed pipe 2, the external control equipment controls the discharge electrode 3 to attach a charge to the passing glass microspheres. As a result, the glass microspheres will be attracted and rolled downwards and collected as they pass the outer side of the stepped guide plate 52 and stepped guide plate 53 on the side of the torsion guide plate 51.

[0051] During the above process, the control equipment will also connect the ends of the high-pressure air pipe 44, the inlet ring pipe 7, and the outlet ring pipe 8 to the external air pump and the circulating water pump respectively. After the high-pressure air pipe 44 is connected to the external air source, it will be sprayed out through the guide nozzle 46 at the other end of the high-pressure air pipe 44, so that the airflow forms a spiral air curtain on the surface of the cone guide block 42. This not only allows the vertically falling glass microspheres to be guided to one side of each torsion guide plate 51 through the air curtain, but also avoids the glass microspheres from directly contacting the surface of the cone guide block 42, thus providing a buffer.

[0052] When the glass microspheres are located on one side of the torsion guide plate 51, the operation of the external circulating water pump will allow the inlet ring pipe 7 to inject coolant into the interior of the water cooling pipe 54, and discharge it from the outlet head 56 at the bottom of the water cooling pipe 54 into the outlet ring pipe 8 and circulate continuously, thereby reducing the surface temperature of the torsion guide plate 51 and thus performing preliminary water cooling on the glass microspheres. Meanwhile, the air cooling pipe 57 on the back of the torsion guide plate 51 will be connected to the gas distribution connection pipe 45 around the high pressure gas pipe 44, so that the air cooling nozzle 58 can perform air cooling on the front end of each torsion guide plate 51, thereby performing water cooling and air cooling in combination on the glass microspheres to improve the cooling efficiency.

[0053] When the glass microspheres are guided by the torsion guide plate 51, the torsion guide plate 51 is in a torsion state, and the stepped guide plates 52 and 53 arranged alternately on the surface of the torsion guide plate 51 increase the travel distance of the glass microspheres. This allows the electrode adsorption plates inside the stepped guide plates 52 and 53 to adsorb the glass microspheres with a greater probability. At the same time, due to the increase in the number of adsorbed microspheres and their accumulation, they move downward along the overall trend of the surface of the torsion guide plate 51 and are discharged from the discharge hopper 6 at the bottom of the cylinder 1 under the guidance of the stepped guide plates 52 and 53 for collection.

[0054] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
