Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a precision feeding device that does not require disassembly and cleaning. Background Technology

[0002] With the continuous development of industrial production, especially in industries such as chemicals, food processing, and pharmaceuticals, the accuracy and cleanliness of material feeding have a crucial impact on product quality and production efficiency. Traditional feeding equipment often suffers from problems such as low accuracy, difficult cleaning, and residual materials. This not only affects the efficiency and safety of the production process but may also lead to inconsistent product quality and increased production costs. Therefore, improving feeding accuracy, enhancing equipment cleaning efficiency, and ensuring the purity of materials have become important directions for the technological improvement of current feeding equipment.

[0003] Existing feeding devices mostly employ simple mechanical structures and low-precision feeding and weighing systems, which cannot accurately control the amount of material fed, resulting in significant feeding errors. This is particularly problematic in applications requiring high-precision material feeding control, such as certain chemical reactions, food ingredient preparation, or pharmaceutical manufacturing, where such errors can even lead to serious quality issues. Furthermore, traditional feeding equipment often fails to thoroughly clean itself during material changes, leaving material residues that affect subsequent production processes. Cross-contamination is especially prevalent when changing between different materials, potentially impacting product compliance and safety. Therefore, this invention provides a precision feeding device that requires no disassembly or cleaning. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention discloses a precision suction and feeding device that requires no disassembly or cleaning. The device includes a suction and feeding unit connected to an external negative pressure vacuum feeder. The suction and feeding unit comprises two symmetrically distributed feeding components, both connected to a mixing component. The device also includes a maintenance platform. A guardrail and a connecting frame are fixedly installed on the upper surface of the maintenance platform, enclosing the upper surface. A ladder is fixedly installed on one side of the maintenance platform, connecting to the guardrail, and an opening is provided at the connection point between the ladder and the guardrail.

[0005] Furthermore, a set of the feeding components includes two hoppers, each hopper having a subtractive weighing module fixedly installed on it. The subtractive weighing module is fixedly connected to the connecting frame, and a U-shaped screw feeder is fixedly installed at the bottom of each hopper.

[0006] Furthermore, another set of the feeding components includes two hoppers, each hopper having a subtraction weighing module fixedly installed on it. The hoppers are fixedly connected to the connecting frame, and a double-helix precision feeder is fixedly installed at the bottom of each hopper.

[0007] Furthermore, the discharge ports of the two U-shaped screw feeders and the two twin screw precision feeders are all connected to additive weighing hoppers, and the discharge ports of the four additive weighing hoppers are all connected to a high-speed twin ribbon mixer. The high-speed twin ribbon mixer is fixedly connected to the maintenance platform, and the discharge port of the high-speed twin ribbon mixer is connected to a U-shaped screw feeder.

[0008] Furthermore, each of the two hoppers is equipped with a cleaning assembly, and each of the two hoppers is connected to a vacuum power source turbine fan, which is connected to the cleaning assembly.

[0009] Furthermore, each of the two silos is equipped with a cap, and a vacuum pipeline is fixedly installed on the cap. The vacuum pipeline is connected to the vacuum power source turbine blower through a pipe, and a vacuum switching butterfly valve is installed on the vacuum pipeline.

[0010] Furthermore, the cleaning assembly includes a cleaning agent and clean water inlet, a high-temperature gas inlet, and a filter backflush air manifold. A filter backflush air manifold is provided near the upper end of either hopper one or hopper two. The cleaning agent and clean water inlet is fixedly installed on the end cap. A universal nozzle is provided on one end of the cleaning agent and clean water inlet that extends into the end cap. The high-temperature gas inlet is fixedly installed on the end cap.

[0011] The beneficial effects of this invention compared with the prior art are: (1) This invention uses a negative pressure vacuum feeder to transport the corresponding material from the suction point to the storage bin 1 for temporary storage. The material is weighed by the subtraction weighing module. The material is weighed by the subtraction weighing module and the additive weighing bin superposition algorithm, thereby achieving a feeding accuracy of 0.03%, improving the feeding accuracy, and ensuring the smooth operation of subsequent operations. When the additive weighing bin reaches the set weight, the butterfly valve opens and the material is fed into the high-speed double ribbon mixer. The high-speed double ribbon mixer starts according to the set time. After the mixing is completed, the material of the predetermined weight is fed to the final receiving point by the U-shaped screw feeder 2 and the subtraction weighing system on the high-speed double ribbon mixer, improving the practicality of the device, reducing the error rate, and ensuring the accuracy requirements of subsequent operations; (2) This invention uses a filter backflush air bag, cleaning agent and clean water inlet, universal nozzle and high temperature gas inlet to facilitate the cleaning of the material cylinder 1 and material cylinder 2 when the material needs to be replaced after the current material is used up. This ensures that no other material will remain when different materials are fed next time, and ensures the purity of the material. Attached Figure Description

[0019] Example: Figures 1-3As shown, a precision suction and feeding device that does not require disassembly and cleaning includes a suction and feeding device connected to an external negative pressure vacuum feeder. The suction and feeding device includes two sets of symmetrically distributed feeding components, which are connected to a mixing component. The suction and feeding device also includes a maintenance platform 1. A guardrail 3 and a connecting frame 12 are fixedly installed on the upper surface of the maintenance platform 1. The guardrail 3 encloses the upper surface of the maintenance platform 1. A ladder 2 is fixedly installed on one side of the maintenance platform 1. The ladder 2 is connected to the guardrail 3, and an opening is provided at the connection between the ladder 2 and the guardrail 3.

[0020] One set of feeding components includes two hoppers 11. A subtractive weighing module 10 is fixedly installed on hopper 11 and is fixedly connected to the connecting frame 12. A U-shaped screw feeder 5 is fixedly installed at the bottom of hopper 11. Another set of feeding components includes two hoppers 13. A subtractive weighing module 10 is fixedly installed on hopper 13 and is fixedly connected to the connecting frame 12. A double screw precision feeder 9 is fixedly installed at the bottom of hopper 13. The outlets of the two U-shaped screw feeders 15 and the two double screw precision feeders 9 are all connected to additive weighing hoppers 6. The outlets of the four additive weighing hoppers 6 are all connected to a high-speed double screw ribbon mixer 7. The high-speed double screw ribbon mixer 7 is fixedly connected to the maintenance platform 1. The outlet of the high-speed double screw ribbon mixer 7 is connected to a U-shaped screw feeder 8.

[0021] Cleaning components are installed on both hoppers 11 and hoppers 23. Vacuum power source turbine blowers 4 are connected to both hoppers 23 and hoppers 11. Vacuum power source turbine blowers 4 are connected to the cleaning components. End caps 20 are installed on both hoppers 11 and hoppers 23. Vacuum pipes 19 are fixedly installed on the end caps 20. Vacuum pipes 19 are connected to vacuum power source turbine blowers 4 through pipes. Vacuum switching butterfly valves 17 are installed on vacuum pipes 19.

[0022] The cleaning assembly includes a cleaning agent and clean water inlet 15, a high-temperature gas inlet 18, and a filter backflush air manifold 14. The filter backflush air manifold 14 is installed near the upper end of either hopper 11 or hopper 23. The cleaning agent and clean water inlet 15 is fixedly installed on the end cap 20. A universal nozzle 16 is installed on the end of the cleaning agent and clean water inlet 15 that extends into the end cap 20. The high-temperature gas inlet 18 is fixedly installed on the end cap 20.

[0023] The corresponding material is transported from the suction point to the storage bin 11 by a negative pressure vacuum feeder. It is weighed by the subtraction weighing module 10 and the weighing data is read in real time by an external computer. The weight of the material in the storage bin 11 is displayed on the computer. The feeding accuracy is 0.03% by the superposition of the subtraction weighing module 10 and the additive weighing bin 6 and the maintenance platform 2. When the additive weighing bin 6 reaches the set weight, the butterfly valve opens and the material is fed into the high-speed double ribbon mixer 7. The high-speed double ribbon mixer 7 starts according to the set time. After the mixing is completed, the predetermined weight of material is fed to the final receiving point by the U-shaped screw feeder 2 8 and the subtraction weighing system on the high-speed double ribbon mixer 7. When the current material is exhausted and needs to be replaced, clean water is conveyed through the external clean water conveying device via the cleaning agent and clean water inlet 15. The clean water is then used to clean the inner walls of silo 11 and silo 23 through the universal nozzles 16 on the cleaning agent and clean water inlet 15. The filter back-blowing air manifold 14 is then activated to clean the connection between silo 11 or silo 23 and the end cap 20 by air blowing. After cleaning, the ladder 2 and the weighing silo 6 discharge the cleaned exhaust gas. The vacuum power source turbine fan 4 and the high-temperature gas inlet 18 are then turned on. The air from the vacuum power source turbine fan 4 enters silo 11 and silo 23 through the high-temperature gas inlet 18. The air entering silo 11 and silo 23 is heated by the high-temperature gas inlet 18, and the heated air dries the contents of silo 11 and silo 23.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
