[0001] This utility model relates to the field of glass production technology, specifically to an automatic weighing and mixing device for glass batch materials. Background Technology

[0002] In the glass manufacturing industry, the preparation of glass batches, that is, the material after various raw materials are mixed in proportion, is a crucial front-end process.

[0003] However, glass batches contain a large amount of powdery materials, such as soda ash and limestone powder. In these stages, especially during the feeding process from the weighing hopper to the mixing tank, severe dust pollution is easily generated. Existing equipment often lacks adequate dust control measures or only uses simple fixed covers, resulting in low dust removal efficiency. The resulting dust escape seriously pollutes the working environment and endangers the health of operators. Therefore, an automatic weighing and mixing device for glass batches is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 An automatic weighing and mixing device for glass batch materials in this embodiment includes a mixing tank 1 and a support 2 fixedly connected to the top of the mixing tank 1. Two feeding pipes 3 are fixedly connected to the inner side of the support 2. A weighing hopper 4 is fixedly connected to the bottom end of the feeding pipe 3. A discharge valve 5 is fixedly connected to the discharge end of the weighing hopper 4. Dustproof components for dust prevention are provided on both the left and right sides of the support 2.

[0023] Please see Figure 1 In this embodiment, the dustproof component includes two first motors 6, which are fixedly connected to the left and right sides of the bracket 2 respectively. The output shaft of the first motor 6 is fixedly connected to a connecting rod 7. The other end of the connecting rod 7 is fixedly connected to a flip-top sealing plate 8. The top of the flip-top sealing plate 8 is fixedly connected to a dust collection disc 9. A three-headed hose 10 is fixedly connected between the tops of the two dust collection discs 9. A collection box 11 is fixedly connected to the outlet end of the three-headed hose 10. A connecting pipe 12 is fixedly connected to the bottom of the collection box 11. A negative pressure fan 13 is fixedly connected to the bottom end of the connecting pipe 12.

[0024] Specifically, the two flip-up sealing plates 8 are rotatably connected between the inner left and right side walls of the corresponding feeding pipe 3.

[0025] It should be noted that the flip-top sealing plate 8 is flipped by the connecting rod 7 driven by the first motor 6. Its function is dual: during the feeding period, the two flip-top sealing plates 8 are in a horizontal closed state, forming a sealing cover to completely seal the lower port of the feeding pipe 3, physically preventing dust from overflowing. During non-feeding periods and when the lower port of the feeding pipe 3 needs to be cleaned, the two flip-top sealing plates 8 flip downwards and open.

[0026] Specifically, the bottom of the vacuum tray 9 is provided with several short vacuum tubes, and the inner side of the flip-up sealing plate 8 has a receiving opening equal to the number of short vacuum tubes.

[0027] Specifically, a feed valve 14 is fixedly connected to the back of each of the two feeding pipes 3. A conveying pipe 15 is fixedly connected to the feed end of the feed valve 14, and a fixed pipe 16 is fixedly connected to the discharge end of the feed valve 14. One end of the fixed pipe 16 passes through the back of the corresponding feeding pipe 3 and extends to the inside of the corresponding feeding pipe 3. The feeding pipe 3 is located below the flip-top sealing plate 8.

[0028] It should be noted that this design ensures that the material always falls within the relatively enclosed space formed by the feeding pipe 3, and even if dust is generated, it is confined within this space.

[0029] Specifically, a baffle 17 is fixedly connected between the inner left and right side walls of the collection box 11, and a support plate 18 is fixedly connected to the bottom of the collection box 11. The support plate 18 is fixedly connected between the inner left and right side walls of the bracket 2. The bracket 2 has two openings on its inner side that are compatible with the feeding pipe 3. The two feeding pipes 3 are fixedly connected to the support plate 18 through their respective openings.

[0030] It should be noted that the baffle 17 inside the collection box 11 serves to separate gas and solids, preventing dust from adhering to the fan impeller and affecting its performance or causing damage.

[0031] Specifically, a second motor 19 is fixedly connected to the right side of the mixing box 1. A transmission rod 20 is fixedly connected to the output shaft of the second motor 19. A transmission gear 21 is fixedly connected to the left end of the transmission rod 20. A driven gear 22 meshes with the bottom of the transmission gear 21. A driven rod 23 is fixedly connected to the inner side of the center of the driven gear 22. Mixing blades 24 are fixedly connected to the outer sides of both the transmission rod 20 and the driven rod 23.

[0032] It should be noted that the second motor 19 drives the two sets of mixing blades 24 to rotate in opposite directions within the mixing box 1 through a transmission system consisting of a transmission rod 20, a transmission gear 21, a driven gear 22, and a driven rod 23. This design generates strong shearing and convection motion, enabling the components of the glass batch to quickly achieve uniform mixing, thus improving mixing efficiency and quality.

[0033] The working principle of the above embodiments is as follows:

[0034] During the feeding stage, the two flip-top sealing plates 8 are in a horizontal closed state, so that the lower end of the feeding pipe 3 is in a relatively closed state to prevent dust from overflowing. Then, the negative pressure fan 13 is started. The negative pressure fan 13 draws air into the collection box 11 through the connecting pipe 12 to generate negative pressure inside. This negative pressure is transmitted to the two dust collection discs 9 through the three-headed hose 10, so that the dust collection short pipe of the dust collection disc 9 generates continuous suction force and the dust is adsorbed through the dust collection disc 9. Finally, the dust is collected and transported to the collection box 11 through the three-headed hose 10.

[0035] At the same time, the material is weighed by the weighing hopper 4. The weighed material falls into the mixing box 1 through the discharge valve 5. Then the second motor 19 is started. The second motor 19 drives the transmission gear 21 to rotate through the transmission rod 20. The transmission gear 21 drives the driven rod 23 to rotate through the driven gear 22 that meshes with it. At this time, the two mixing blades 24 start to rotate to mix the material.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
