Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a vacuum adsorption type glass separator powder recovery device. Background Technology

[0002] The separating powder is a white, powdery industrial auxiliary material primarily used in the production of contact products. In the glass industry, this powder is applied to the glass surface using a mechanized spraying process, providing composite functions such as mildew prevention, surface smoothing, and high-temperature resistance to meet long-term application requirements at 65℃. However, existing powder spraying equipment, due to the mist-like spraying of the separating powder, results in powder scattering and significant waste. The following problems exist with the existing technology:

[0003] When glass isolation powder is sprayed onto the glass surface using a powder spraying device, the distance between the glass and the powder suction head cannot be adjusted in height. Furthermore, the fine powder is intercepted by the filter cotton as it passes through the air. After the process is completed, the filter cotton is inconvenient to disassemble and clean, which is quite cumbersome and affects the recycling efficiency. In addition, the glass isolation powder falls into the storage bin for storage, but because the powder is very fine, the powder retrieval process is also quite cumbersome. Utility Model Content

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a vacuum adsorption type glass separator powder recovery device, which employs a combination of a recovery box, a vacuum pump, a material extraction pipe, a powder suction head, a mounting shell, a lifting mechanism, a recovery pipe, and a filter assembly. The filter assembly is magnetically fixed in the communication port on the recovery box. The lifting mechanism controls the powder suction head to move up and down to a suitable height. The vacuum pump operates, extracting air from the powder suction head through the material extraction pipe, creating a vacuum environment lower than atmospheric pressure. External materials are drawn into the recovery pipe under the vacuum pressure difference, while the airflow carries... The material enters the recycling bin, where glass separating powder and air are separated by a filter assembly. The glass separating powder is intercepted and recycled within the recycling bin by the filter element. After the process, the filter assembly can be easily disassembled and cleaned to prevent clogging. This solves the problems that arise when glass separating powder is sprayed onto glass surfaces using powder coating equipment. For example, the distance between the glass and the powder suction head cannot be adjusted, and the fine powder is intercepted by the filter cotton after the process, making the filter cotton difficult to disassemble and clean, thus affecting recycling efficiency. This method achieves the beneficial effects of convenient height adjustment of the powder suction head and easy installation and removal of the filter assembly.

[0016] 2. This utility model provides a vacuum adsorption type glass separator powder recovery device. It adopts the cooperation between a recovery box, a U-shaped base and a feeding mechanism. When the glass separator powder stored in the recovery box is taken out, the movable door on the recovery box is opened, and then the electric telescopic rod is operated. The output end of the electric telescopic rod drives the tray to push upward, so that the tray tilts along the baffle. Under the influence of gravity, the glass separator powder slides out along the discharge port. This solves the problem that the glass separator powder falls into the storage box and is stored. However, because the glass separator powder is fine, the powder removal process is relatively cumbersome. This device achieves the beneficial effect of conveniently taking out the recovered glass separator powder. Attached Figure Description

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1As shown, this utility model provides a vacuum adsorption type glass separation powder recovery device, including a recovery box 1.

The top of the outer wall of the feeding mechanism 9 penetrates to the inside of the recovery box 1.

[0025] The system consists of a recycling bin 1, a vacuum pump 2, a material extraction pipe 3, a powder suction head 4, a mounting shell 5, a lifting mechanism 6, a recycling pipe 7, a filter assembly 8, and a discharging mechanism 9. Through the coordinated operation of the mounting shell 5, the lifting mechanism 6, and the powder suction head 4, the height of the powder suction head 4 can be adjusted by controlling the lifting mechanism 6. This allows for easy adjustment of the position between the powder suction port of the powder suction head 4 and the glass, facilitating vacuum adsorption cleaning of the glass separation powder floating in the air. The filter assembly 8 is magnetically installed and fixed, with the filter element 82 intercepting and recycling the glass separation powder into the recycling bin 1 between the air and the glass separation powder. This also facilitates the disassembly and cleaning of the filter assembly 8, preventing blockage. When removing the glass separation powder stored in the recycling bin 1, the discharging mechanism 9 allows the accumulated glass separation powder to be tilted and slid out easily.

[0026] like Figure 2As shown, this utility model provides a technical solution for a vacuum adsorption type glass separator powder recovery device: the lifting mechanism 6 includes a stepper motor 61, a lead screw 62, a moving block 63, two slide rods 64, two sliders 65, a top plate 66, and a bottom plate 67.

The outer walls of the two slide rods 64 respectively extend through the upper and lower ends of the two sliders 65. The ends are slidably connected.

[0027] like Figure 3 As shown, this utility model provides a technical solution for a vacuum adsorption type glass separator powder recovery device: the filter assembly 8 includes a mounting frame 81, a filter element 82, a positioning frame 83, several magnetic pieces 84, and a sealing strip 85. The outer wall of the filter element 82 is fixedly connected to the inner wall of the mounting frame 81, the inner wall of the positioning frame 83 is fixedly connected to one side of the outer wall of the mounting frame 81, the inner wall of the sealing strip 85 is fixedly connected to the side of the outer wall of the mounting frame 81 near the positioning frame 83, and the surfaces of several magnetic pieces 84 are equidistantly arrayed and fixedly connected to one end of the outer wall of the positioning frame 83 near the sealing strip 85. The sealing strip 85 is provided, and the sealing strip 85 is pressed and adhered to the inner wall of the communication port 101 to increase the sealing performance of the mounting frame 81.

[0028] like Figure 4As shown, this utility model provides a technical solution for a vacuum adsorption type glass separator powder recovery device: Iron frame strips 11 are fixedly connected to the outer sides of the left and right ends of the recovery box 1 near the connecting port 101. The outer wall of the mounting frame 81 engages with the inner wall of the connecting port 101. The outer surface of the sealing strip 85 overlaps the inner wall of the connecting port 101. The surface of the magnet 84 is magnetically connected to the outer wall of the iron frame strip 11. The filter assembly 8 is connected to the connecting port 101 using magnetic attraction, facilitating disassembly and cleaning of the filter assembly 8 and preventing blockage. The bottom of the right end of the recovery box 1... The part has an inlet 102 that is open to the inside and outside. The inner wall of the inlet 102 is provided with a movable door 12. The top of the inner wall of the inlet 102 is provided with a moving groove 103 that is adapted to the movable door 12. An iron block 13 is fixedly connected to the bottom of the right end of the movable door 12. A magnet block 14 is fixedly connected to the top of the right end of the recycling box 1 near the inlet 102. The top of the iron block 13 and the bottom of the magnet block 14 are magnetically connected. The iron block 13 and the magnet block 14 are fixed by magnetic attraction, which makes it convenient for the movable door 12 to slide along the moving groove 103 to open and position the inlet 102.

[0029] like Figure 5 As shown, this utility model provides a technical solution for a vacuum adsorption type glass separator powder recovery device: the feeding mechanism 9 includes a tray 91, a baffle 92, two positioning rods 93, an electric telescopic rod 94, a U-shaped block 95, and a T-shaped slider 96. The baffle 92 is U-shaped, and its bottom is fixedly connected to the outer wall of the top of the tray 91. One end of the opposite face of the two positioning rods 93 is fixedly connected to the right side of the front and rear ends of the tray 91, respectively. The output end of the electric telescopic rod 94 is rotatably connected to the inner wall of the U-shaped block 95. The bottom of the T-shaped slider 96 is fixedly connected to the horizontal side of the U-shaped block 95. At the top of the tray 91, a T-shaped groove 910 matching the T-shaped slider 96 is provided on the left side of the bottom of the tray 91. The ends of the outer walls of the two positioning rods 93 that are away from each other pass through the outer wall of the recycling box 1 and are movably connected to each other. The positioning rods 93 position the right side of the tray 91, so that when the electric telescopic rod 94 pushes out to the left side of the tray 91, the tray 91 is tilted, which makes it easy to slide the glass isolation powder off and take it out. The bottom of the electric telescopic rod 94 is fixedly connected to the top of the transverse surface of the U-shaped base 10. The outer wall of the T-shaped slider 96 is slidably connected to the inner wall of the T-shaped groove 910.

[0030] The working principle of this vacuum adsorption type glass separator powder recovery device will be explained in detail below.

[0031] like Figure 1-5As shown, during the glass processing, the mounting frame 81 is inserted into the connecting port 101, so that the surface of the sealing strip 85 is pressed against the inner wall of the connecting port 101. The positioning frame 83 is magnetically fixed to the surface of the iron frame strip 11 by the magnet 84, thus realizing the installation of the filter component 8. When the powder spraying equipment acts on the glass surface through a mechanized spraying process, the stepper motor 61 is started. The output shaft of the stepper motor 61 drives the lead screw 62 to rotate, so that the moving block 63 drives the powder suction head 4 to move up and down, so that the powder suction head 4 is adjusted to a suitable height between the powder suction head 4 and the sprayed glass. Then, the vacuum pump 2 is operated to work, and the air in the powder suction head 4 is extracted through the extraction pipe 3 to form a vacuum environment lower than the external atmospheric pressure. Under the action of the vacuum pressure difference, the external material is sucked into the recovery pipe 7. The airflow carries the material into the recycling bin 1. The glass separation powder is separated from the air by the filter element 82, which intercepts and collects the glass separation powder in the recycling bin 1 for storage. This achieves vacuum adsorption cleaning of the glass separation powder scattered in the air. When the glass separation powder stored in the recycling bin 1 is taken out, the iron block 13 drives the movable door 12 to move upward along the moving groove 103, so that the iron block 13 is magnetically attracted to the bottom of the magnet block 14, thereby opening the discharge port 102. By operating the electric telescopic rod 94, the output end of the electric telescopic rod 94 pushes upward, so that the right side of the tray 91 is lifted upward by the positioning rod 93, which drives the T-shaped slider 96 on the U-shaped block 95 to slide along the T-shaped slide groove 910, thereby causing the glass separation powder on the tray 91 to slide out from the discharge port 102 under the influence of gravity.

[0032] The vacuum pump 2, stepper motor 61 and electric telescopic rod 94 used are all existing products in terms of specific type and structure, and the specific circuit connection structure and control relationship are also existing technologies, which will not be elaborated on here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
