Description

Technical Field

[0001] This disclosure relates to the technical field of glass microsphere production equipment, specifically to glass microsphere drying equipment. Background Technology

[0002] Hollow glass microspheres possess characteristics such as high compressive strength, high melting point, high resistivity, and low thermal conductivity and coefficient of thermal shrinkage, making them widely applicable in fields such as petroleum industry, aerospace, 5G communications, new high-speed trains, automobiles and ships, thermal insulation coatings, and adhesives. The powder preparation process for hollow glass microspheres involves quenching, drying, and grinding molten glass to produce powder with a suitable particle size distribution. The resulting powder is then subjected to high-temperature spheroidization, cooled, and collected using methods such as hydraulic flotation, drying, and sieve classification to obtain the hollow glass microspheres.

[0003] A search revealed that patent CN220524588U discloses a drying device for glass microsphere production, comprising a housing with a drying zone and two cylindrical lifting zones located on either side of the drying zone. The lifting zones are separated from the drying zone by a partition. The upper end of the partition has a discharge port for the lifting zone, and the lower end has a feed port for the lifting zone. An auger is installed within the lifting zone… As the glass microspheres fall downwards, they are dried by air blowing through a pipe. Subsequently, the glass microspheres enter the lifting zone via a return ramp and are lifted again, falling from the discharge port onto a sieve plate, where they are dried by air blowing. This process is repeated to ensure the drying effect of the glass microspheres. However, this application cannot sieve the glass microspheres by size, requiring grading in different equipment, resulting in low production efficiency. Furthermore, the glass microspheres are prone to moisture absorption during transport, affecting the drying effect.

[0004] In summary, improving production efficiency while preventing glass microspheres from becoming damp is a pressing technical problem that needs to be solved. Therefore, we propose a glass microsphere drying equipment. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a glass microsphere drying equipment, including a support base, a housing disposed on top of the support base, lifting components and partitions disposed on both sides inside the housing, a sieve plate installed between the two partitions by a mounting component, a discharge port opened on the partition, an air blowing pipe disposed below the sieve plate and located on the partition, a uniform feeding component disposed on the top of the housing, sealing components symmetrically disposed on the outside of the housing, and a return ramp disposed on the bottom wall inside the housing.

[0006] Two rectangular holes are formed on the upper and lower surfaces of the housing;

[0007] The drying equipment also includes a screening component, which includes two frames corresponding to the rectangular holes. A first screen and a second screen are respectively installed in each frame. The inner diameter of the mesh of the second screen, which is placed below, is smaller than the inner diameter of the mesh of the first screen.

[0008] A driving component, which is connected to the filtering component, is used to drive the frame to enter or exit the housing through the rectangular hole.

[0009] According to the technical solution provided in the embodiments of this application, a support plate extends outward from the surface of the housing, and the driving assembly includes an electric push rod disposed on the top of the support plate. The output end of the electric push rod is connected to a fixing plate, and the fixing plate is connected to the two frames away from the end of the electric push rod.

[0010] According to the technical solution provided in the embodiments of this application, the frame and the partition are slidably connected.

[0011] According to the technical solution provided in the embodiments of this application, two sliding grooves are provided on opposite sides of the two partitions, and sliding plates adapted to the sliding grooves are symmetrically fixedly connected to the outer side of the frame.

[0012] According to the technical solution provided in the embodiments of this application, the front and rear end faces of the partition are fixedly connected to the front and rear sides of the inner wall of the shell, respectively, and the front end of the sliding groove extends to the surface of the shell.

[0013] According to the technical solution provided in the embodiments of this application, the bottom end face of the fixing plate is at the same horizontal plane as the bottom side of the frame, and the top end face of the fixing plate is slidably connected to the top end face of the support plate.

[0014] According to the technical solution provided in the embodiments of this application, the sliding plate is slidably connected to the inner wall of the sliding groove, and the frame near the support plate is slidably connected to the top surface of the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] After drying, when the glass microspheres need to be graded and screened, the drive assembly moves the two first and second screens into the interior of the housing. The glass microspheres are then lifted to a certain height and discharged through the outlet onto the screen plate. The glass microspheres pass through the screen plate and fall onto the top of the first screen. The first screen filters out glass microspheres larger than its aperture and leaves them on top, while glass microspheres smaller than its aperture fall onto the top of the second screen, and glass microspheres larger than its aperture are filtered out and remain on the second screen. Glass microspheres smaller than the second screen aperture fall into the bottom of the housing. The sealing element is then removed, allowing the glass microspheres at the bottom of the housing to be taken out. The drive assembly moves the first and second screens to the outside of the housing, allowing the glass microspheres filtered out by the first and second screens to be removed. This achieves multi-stage sieving of glass microspheres. In summary, this application has the function of sieving glass microspheres, and the drying and sieving of glass microspheres are carried out in the same equipment, thus improving production efficiency and eliminating the need for a transfer process.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] As mentioned in the background section, existing technologies cannot sieve glass microspheres by size, thus requiring sieving in different equipment. This results in low production efficiency and the glass microspheres are prone to moisture absorption during transport, affecting the drying effect.

[0024] Example:

[0025] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution for a glass microsphere drying equipment, including a support base 1, a shell 2 set on top of the support base 1, lifting components 5 and partitions 11 set on both sides inside the shell 2, a sieve plate 13 installed between the two partitions 11 through an installation component 14, a discharge port 15 opened on the partitions 11, an air blowing pipe set below the sieve plate 13 and located on the partitions 11, a uniform feeding component 3 set on top of the shell 2, sealing components 4 symmetrically set on the outside of the shell 2, and a return ramp set on the bottom wall inside the shell 2. The air blowing pipe extends out of the shell 2 and is connected to a fan. An air outlet pipe is set on the shell 2 and is connected to a dehumidifier. The partitions 11, air blowing pipe, sieve plate 13, lifting components 5, installation components 14, uniform feeding component 3, and sealing components 4 are all existing technologies. Their structure and working principle are based on a drying device for glass microsphere production with publication (announcement) number CN220524588U, and will not be described in detail here.

[0026] Two rectangular holes 6 are formed on the top and bottom surfaces of the housing 2;

[0027] The drying equipment also includes a screening component, which includes two frames 7 corresponding to the rectangular holes 6. Each frame 7 has a first screen 8 and a second screen 18 installed in it. The inner diameter of the mesh of the second screen 18 placed below is smaller than that of the first screen 8.

[0028] The drive assembly and the filter assembly are connected to drive the frame 7 to enter or exit the housing 2 through the rectangular hole 6.

[0029] After drying, when the glass microspheres need to be graded and screened, the drive assembly moves the two first screens 8 and the second screen 18 into the interior of the housing 2. The glass microspheres are then lifted to a certain height and discharged through the outlet onto the screen plate 13. The glass microspheres pass through the screen plate 13 and fall onto the top of the first screen 8. The first screen 8 filters out glass microspheres larger than its aperture and leaves them on top of the first screen 8, while glass microspheres smaller than its aperture fall onto the top of the second screen 18. Similarly, glass microspheres larger than their aperture fall onto the top of the second screen 18, while glass microspheres smaller than their aperture fall to the bottom of the housing 2. Then, the sealing member 4 is removed, allowing the glass microspheres at the bottom of the housing 2 to be removed. The drive assembly then moves the first screens 8 and the second screen 18 to the outside of the housing 2, allowing the glass microspheres filtered out by the first screens 8 and the second screen 18 to be removed, thus achieving multi-stage screening of the glass microspheres.

[0030] In a preferred embodiment, a support plate 9 extends outward from the surface of the housing 2. The driving assembly includes an electric push rod 10 disposed on the top of the support plate 9. The output end of the electric push rod 10 is connected to a fixed plate 16. The end of the fixed plate 16 away from the electric push rod 10 is connected to two frames 7. After drying, when the glass microspheres need to be graded, the electric push rod 10 is controlled to move the fixed plate 16. The movement of the fixed plate 16 moves the two frames 7. The frames 7 move into the interior of the housing 2 through the rectangular hole 6. When the back of the frame 7 contacts the inner wall of the housing 2, the operation of the electric push rod 10 is stopped. At this time, the surface of the frame 7 and the surface of the housing 2 are at the same level. Then, the lifting assembly 5 is controlled to lift the glass microspheres to a certain height and discharge them through the outlet 1. 5. The glass microspheres are discharged onto the sieve plate 13 and fall through the sieve plate 13 to the top of the first sieve 8. The first sieve 8 filters out glass microspheres larger than the aperture of the first sieve 8 and leaves them on the top of the first sieve 8, while glass microspheres smaller than the aperture of the first sieve 8 fall to the top of the second sieve 18, and glass microspheres larger than the aperture of the second sieve 18 are filtered out and left on the top of the second sieve 18, while glass microspheres smaller than the aperture of the second sieve 18 fall to the bottom of the inner shell 2. Then, the sealing part 4 is removed, and the glass microspheres at the bottom of the inner shell 2 can be taken out. The control electric push rod 10 is operated to retract, which can drive the first sieve 8 and the second sieve 18 to the outside of the shell 2, so that the glass microspheres filtered out by the first sieve 8 and the second sieve 18 can be removed, thereby realizing multi-stage sieving of glass microspheres.

[0031] A fixing plate 16 is fixedly connected to the surface of the two frames 7. The output end of the electric push rod 10 is fixedly connected to the fixing plate 16. The two frames 7 are slidably connected between the two partitions 11. The left and right sides of the inner walls of the two frames 7 are respectively equipped with a first screen 8 and a second screen 18 through the mounting assembly 14. The first screen 8 is located above the second screen 18. The aperture of the first screen 8 is larger than that of the second screen 18. Vibrators are symmetrically arranged on the top of the first screen 8, the second screen 18 and the sieve plate 13. The vibrators play the role of vibrating and breaking up the glass microspheres.

[0032] In a preferred embodiment, the frame 7 is slidably connected to the partition 11, thereby improving the stability of the frame 7 during movement.

[0033] Please see Figure 1 , Figure 2 and Figure 3Two sliding grooves 12 are provided on opposite sides of the two partitions 11. Slide plates 17 that are adapted to the sliding grooves 12 are symmetrically fixedly connected to the outer side of the frame 7. The cooperation between the slide plates 17 and the sliding grooves 12 limits the frame 7 and improves the stability of the frame 7 when it moves. The front and rear end faces of the partitions 11 are fixedly connected to the front and rear sides of the inner wall of the shell 2, respectively. The front end of the sliding grooves 12 extends to the surface of the shell 2.

[0034] like Figure 1 As shown, the housing 2 is rectangular, with the front and rear directions parallel to the width direction of the housing 2. The partitions 11 are distributed and arranged along the length direction of the housing 2. The rectangular holes are opened on the front wall of the housing 2, avoiding the partitions 11. The front end of the sliding groove 12 is close to the front wall of the housing 2.

[0035] Please see Figure 3 The bottom surface of the fixed plate 16 is at the same level as the bottom side of the frame 7. The fixed plate 16 is slidably connected to the top surface of the support plate 9, which improves the stability of the fixed plate 16 when it moves. The slide plate 17 is slidably connected to the inner wall of the sliding groove 12. The frame 7 near the support plate 9 is slidably connected to the top surface of the support plate 9. When the electric push rod 10 moves the fixed plate 16, the frame 7 moves on the top of the support plate 9, which improves the stability of the frame 7 when it moves.

[0036] Working principle: After drying, when the glass microspheres need to be graded and screened, the electric push rod 10 is controlled to move the fixed plate 16. The movement of the fixed plate 16 moves the two frames 7. The frames 7 move through the rectangular holes 6 into the interior of the shell 2. When the back of the frame 7 contacts the inner wall of the shell 2, the electric push rod 10 stops working. At this time, the surface of the frame 7 and the surface of the shell 2 are at the same level. Then, the lifting component 5 is controlled to lift the glass microspheres to a certain height and discharge them through the discharge port 15 onto the screen plate 13. The glass microspheres pass through the screen plate 13 and fall onto the top of the first screen 8. The first screen 8 screens glass microspheres larger than the aperture of the first screen 8. Glass microspheres are screened out and remain on top of the first screen 8, while glass microspheres smaller than the aperture of the first screen 8 fall to the top of the second screen 18, and glass microspheres larger than the aperture of the second screen 18 are screened out and remain on top of the second screen 18, while glass microspheres smaller than the aperture of the second screen 18 fall to the inner bottom of the housing 2. Then, the sealing part 4 is removed, and the glass microspheres at the inner bottom of the housing 2 can be taken out. The electric push rod 10 is controlled to retract, which can move the first screen 8 and the second screen 18 to the outside of the housing 2, so that the glass microspheres screened out by the first screen 8 and the second screen 18 can be removed, thereby realizing multi-stage screening of glass microspheres.

[0037] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed.
