Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to a solid particle additive device. Background Technology

[0002] In the chemical industry, solid particulate additive dosing devices are widely used for the precise addition of particulate materials such as catalysts, adsorbents, packing materials, and modifying agents. They are primarily used in chemical reactions, adsorption separation, gas-liquid absorption, and particulate transport in special environments. For example, the quantitative addition of catalysts can control reaction rates, adsorbent dosing is used for gas purification and wastewater treatment, and the uniform distribution of packing materials improves the efficiency of reaction towers or separation towers. Through intelligent control and the application of durable materials, this device can meet the diverse needs of chemical processes, improving production efficiency and product quality.

[0003] A solid granular additive device mainly consists of a storage silo, a feeding mechanism, a conveying pipeline, a dust control system, and a support frame. The storage silo stores the granular additive, while the feeding mechanism provides a stable supply of materials via a vibrating feeder, screw conveyor, or pneumatic conveying device. The conveying pipeline transports the additive to the target equipment; its sealed design prevents granule leakage, and the dust control system reduces dust pollution. The external support frame provides stability and adaptability. The entire device efficiently and accurately adds granular additives, meeting the diverse needs of the chemical, pharmaceutical, and food industries, improving production efficiency, reducing raw material waste, and ensuring operational safety and environmental protection.

[0004] However, existing technologies for storing solid granular additives have several shortcomings: First, the moisture-proof measures in storage silos are limited, relying mainly on traditional sealing designs or simple desiccants. These methods cannot effectively prevent the continuous infiltration of external moisture and oxygen, leading to hygroscopic granular materials becoming damp, clumping, and oxidizing, thus affecting material quality and the stability of subsequent processes. Second, dust control methods during the feeding of granular additives are relatively simple, mainly relying on physical sealing or negative pressure ventilation. This makes it difficult to comprehensively capture fine particulate dust, resulting in high dust concentrations in the operating environment, which threatens worker health and increases the frequency of equipment cleaning and maintenance.

[0005] To address the above problems, a solid particle additive device is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a solid granular additive device, which aims to solve the problems of incomplete moisture-proof and dust control in existing solid granular additive devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a solid particle auxiliary material adding device, including a vibrating plate and a storage bin, a dust collection mechanism is provided above the vibrating plate, a support base is installed at the bottom of the storage bin, a moisture-proof mechanism is installed on the outside of the storage bin, a feeding mechanism is provided at the top of the storage bin, a water pump is provided on one side of the vibrating plate, and a water inlet pipe is fixedly connected to the input end of the water pump;

[0008] The dust collection mechanism includes a dust collection hood, a dust discharge pipe is installed on the top of the dust collection hood, a dust suppression component is provided on the inner side of the dust collection hood, and a dust cleaning component is provided at the end of the dust discharge pipe away from the dust collection hood.

[0009] As a further description of the above technical solution:

[0010] The dust suppression assembly includes an annular water pipe with multiple nozzles installed at the bottom. Multiple fixed bends are provided on the outer side of the annular water pipe, and a water outlet pipe is fixedly connected inside the annular water pipe.

[0011] As a further description of the above technical solution:

[0012] The dust removal assembly includes a dust removal cylinder, an activated carbon purification cylinder is installed inside the dust removal cylinder, an air outlet pipe is installed at the end of the dust removal cylinder away from the dust discharge pipe, and an exhaust fan is installed inside the air outlet pipe.

[0013] As a further description of the above technical solution:

[0014] The moisture-proof mechanism includes a fixing ring and an exhaust pipe. A gas cylinder is installed on the inner side of the fixing ring, and an air inlet pipe is provided at the output end of the gas cylinder.

[0015] As a further description of the above technical solution:

[0016] The feeding mechanism includes a feeding hopper, and a hopper cover is rotatably connected to the top of the feeding hopper.

[0017] As a further description of the above technical solution:

[0018] The opposite sides of the multiple fixed bending plates are fixedly connected to the inner wall of the dust collection hood, and the bottom of the water outlet pipe is fixedly connected to the output end of the water pump.

[0019] As a further description of the above technical solution:

[0020] The fixing ring is fixedly connected to the outside of the storage bin, and the exhaust pipe and the air inlet pipe are both installed inside the storage bin.

[0021] As a further description of the above technical solution:

[0022] The feed hopper is located on the top side of the storage bin.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, the dust collection hood installed above the vibratory feeder effectively controls dust diffusion through a negative pressure exhaust system, drawing dust generated during the feeding of granular auxiliary materials into the dust collection pipe. An activated carbon filter cartridge deeply purifies the intake air, removing harmful components from the dust. The purified air is then discharged only after it has been deemed safe and harmless, helping to protect worker health and meeting environmental protection requirements. Furthermore, a ring-shaped water pipe is designed inside the dust collection hood, and a fine water mist is sprayed out via a water pump and nozzles, further enhancing the dust control effect. The water mist particles combine with the dust to form larger particles that settle rapidly, significantly reducing dust concentration. This not only optimizes the operating environment but also effectively reduces the frequency of equipment cleaning and maintenance, extending the equipment's service life.

[0025] 2. In this invention, by installing gas cylinders on the outside of the storage silo and filling it with inert gas (such as nitrogen or carbon dioxide), moisture and oxygen in the air can be effectively blocked, reducing the moisture absorption problem of granular additives at its source. This is especially suitable for granular materials that are highly hygroscopic, chemically reactive, or easily oxidized, such as catalysts or special additives. The inert gas creates a protective atmosphere inside the silo, preventing moisture intrusion and reducing oxygen concentration, thus avoiding oxidation or deterioration of the material. Furthermore, this sealed environment can further extend storage time and reduce problems such as clumping, adhesion, or reaction failure caused by moisture. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1-4This utility model provides an embodiment: a solid particle auxiliary material adding device, including a vibratory plate 1 and a storage silo 3. A support base 2 is installed at the bottom of the storage silo 3 to stabilize its structure and ensure the safety and stability of the device operation. A water pump 6 is installed on one side of the vibratory plate 1 to provide water power for the dust suppression component. A water inlet pipe 8 is fixedly connected to the input end of the water pump 6, providing an external water source to ensure stable water flow. A dust collection mechanism 7 is installed directly above the vibratory plate 1 to efficiently collect dust generated during the auxiliary material adding process. The dust collection mechanism 7 includes a dust collection hood 701, with a dust discharge pipe 702 installed on its top to transport the collected dust to a subsequent purification device. A dust suppression component is installed inside the dust collection hood 701, including an annular water pipe 704, which achieves all-round coverage of water mist through its annular design. Multiple nozzles 705 are installed at the bottom of the annular water pipe 704. These nozzles are evenly distributed and pressurize water to spray out a fine water mist, enhancing dust settling. Multiple fixing plates 706 are provided on the outer side of the annular water pipe 704 to securely install it onto the inner wall of the dust collection hood 701, ensuring the accuracy and stability of the water mist spray. The bottom of the outlet pipe 707 is fixedly connected to the output end of the water pump 6, which delivers water to the annular water pipe 704, enabling efficient dust suppression. A dust removal assembly is installed at the end of the dust exhaust pipe 702 furthest from the dust collection hood 701. This assembly further purifies the dust-laden gas output from the dust exhaust pipe 702. The dust removal assembly includes a dust collection cylinder 703, inside which is installed an activated carbon purification cylinder 708. The activated carbon efficiently removes harmful particles and odors through its adsorption properties. An exhaust pipe 709 is installed at the end of the dust collection cylinder 703 furthest from the dust exhaust pipe 702 to discharge the purified air to the outside, ensuring no secondary pollution. An exhaust fan 710 is installed inside the exhaust pipe 709, which powerfully draws dust to the dust removal system, improving dust handling efficiency.

[0035] Reference Figure 1 and Figure 5A moisture-proof mechanism 4 is installed on the outside of the storage silo 3 to effectively prevent the granular auxiliary materials from absorbing moisture, clumping, or oxidizing and failing during storage. The moisture-proof mechanism 4 includes a fixing ring 401 and an exhaust pipe 404. A gas cylinder 402 is installed inside the fixing ring 401. The gas cylinder 402 stores inert gases such as nitrogen or carbon dioxide. The output end of the gas cylinder 402 is connected to the storage silo 3 through an inlet pipe 403, thereby forming a protective atmosphere that isolates moisture and oxygen, significantly improving the stability of the storage environment. The fixing ring 401 is fixedly connected to the outside of the storage silo 3, and the gas cylinder 402 is firmly fixed by a robust mechanical structure to ensure the safe operation of the device. Both the exhaust pipe 404 and the inlet pipe 403 are installed inside the storage silo 3 to achieve gas circulation and pressure balance. The exhaust pipe 404 ensures that excess gas or any moisture it may carry is discharged from the silo in a timely manner, preventing excessive pressure or poor gas exchange. A feeding mechanism 5 is installed on the top of the storage silo 3 to facilitate convenient and sealed feeding of granular auxiliary materials. The feeding mechanism 5 includes a feeding hopper 501, which is located on one side of the top of the storage silo 3, and its inner cavity is connected to the storage silo 3 through an opening. A hopper cover 502 is rotatably connected to the top of the feeding hopper 501. When feeding is required, the hopper cover 502 can be easily opened; after feeding is completed, the hopper cover 502 can be rotated to close, forming a sealed state, effectively preventing external moisture from entering the storage silo 3. To further improve the moisture-proof effect, the contact surface between the feeding hopper 501 and the hopper cover 502 is designed with a sealing strip or gasket to ensure the tightness of the feeding interface.

[0036] Working Principle: Granular auxiliary materials first enter the storage silo 3 from the feed hopper 501 through the feeding mechanism 5. The hopper cover 502 of the feed hopper 501 rotates and closes after feeding, and the sealing strip ensures the tightness of the interface to prevent external moisture from entering the silo. A moisture-proof mechanism 4 is installed on the outside of the storage silo 3. Inert gas in the gas cylinder 402 is injected into the storage silo 3 through the air inlet pipe 403 to form a protective atmosphere, isolating moisture and oxygen, and preventing the granular materials from becoming damp, clumping, or oxidizing and failing. The exhaust pipe 404 promptly discharges excess gas and moisture to achieve internal pressure balance. The granular auxiliary materials at the bottom of the storage silo 3 are evenly conveyed to the subsequent processes by the vibrating plate 1. The dust collection mechanism 7 set above the vibrating plate 1 collects the dust generated during the auxiliary material conveying process. The dust collection hood 701 sends the dust-laden gas into the dust removal cylinder 703 through the dust discharge pipe 702. The activated carbon purification cylinder 708 inside further adsorbs harmful particles and odors, and the purified air is discharged through the air outlet pipe 709. At the same time, the annular water pipe 704 of the dust suppression component sprays fine water mist through the nozzle 705, which combines with the dust and causes it to settle, significantly reducing dust diffusion.
