Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, specifically relating to a pulse dust collector for use in feed production workshops. Background Technology

[0002] Feed production refers to providing the necessary nutrients for animals such as livestock, poultry, and aquatic animals. Through processing, raw materials are transformed into feed products suitable for animal consumption. This process involves multiple stages, including raw material selection, formulation design, processing technology, and quality control. The goal is to produce high-quality feed that meets the growth, production, and health needs of animals. The basic steps of feed production typically include raw material procurement, raw material processing, ingredient mixing, pressing, drying, grinding, and packaging. Feed raw materials can be plant-based, animal-based, or mineral-based, such as corn, soybeans, fish meal, bone meal, vitamins, and minerals.

[0003] In the feed production process, the crushing, mixing, conveying, and packaging of raw materials generate a large amount of dust, which not only pollutes the workshop environment and affects worker health, but may also cause safety accidents such as dust explosions. Therefore, feed production workshops must be equipped with efficient dust removal equipment to reduce dust concentration and ensure production safety and environmental hygiene. Currently, pulse-jet dust collectors are commonly used in feed production workshops for dust removal. During the dust removal process, pulse gas can be used to back-flush and clean the dust collector bags. However, since the dust collector bags are located inside the dust collector, the dust collector needs to be disassembled when replacing the dust collector bags, resulting in low replacement efficiency. To address these issues, we propose a pulse-jet dust collector for feed production workshops. Utility Model Content

[0020] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1-4 As shown, a pulse dust collector for a feed production workshop includes a dust collector housing 1. A dust collection hopper 11 is fixedly connected to the bottom surface of the dust collector housing 1. An air outlet 16 and an air inlet 21 are opened on one side of the dust collector housing 1. A negative pressure fan 15 is installed on one side of the dust collector housing 1. An exhaust pipe 14 is fixedly connected to the exhaust end of the negative pressure fan 15. The exhaust pipe 14 is connected to the air outlet 16. An air inlet pipe 5 is fixedly connected to one side of the dust collector housing 1 through an air inlet valve 4. The air inlet pipe 5 is connected to the air inlet valve 4. During pulse cleaning, the air inlet valve 4 is closed to prevent dust from being sprayed out. The negative pressure fan 15 and the air inlet pipe 5 work together to enhance the dust adsorption capacity, ensuring that high-concentration dust in the feed production workshop is collected efficiently, reducing environmental pollution and safety hazards.

[0022] Two guide rails 17 are fixedly connected to the inner wall of the dust collector housing 1. A sliding plate 18 is slidably connected between the two guide rails 17. A support frame 22 is fixedly connected to the outer surface of the sliding plate 18. A dust collector bag 19 is installed on the outer surface of the support frame 22 through a fixing hoop 25. A connecting plate 27 is fixedly connected to the upper surface of the sliding plate 18. A threaded sleeve 23 is fixedly embedded in the middle of the connecting plate 27. A lead screw 24 is connected to the internal thread of the threaded sleeve 23. The outer surfaces of both ends of the lead screw 24 are connected to the dust collector housing 1 through bearings. A drive motor 3 is installed on the back of the dust collector housing 1. The output end of the drive motor 3 is connected to one end of the lead screw 24. The drive motor 3 drives the lead screw 24 to rotate, causing the sliding plate 18 to move along the guide rails 17. The dust collector bag 19 can be quickly pulled out from the dust collector housing 1 without disassembling the entire dust collector, which greatly improves the replacement efficiency and reduces maintenance costs.

[0023] A pulse valve 2 is installed on the upper surface of the dust collector housing 1. The pulse valve 2 is a diaphragm valve controlled by a pilot valve such as an electromagnetic or pneumatic one, capable of instantly opening and closing a high-pressure air source to generate pulses. As a known technology, the pulse valve 2 is a key component of the baghouse dust collector, capable of over 1 million pulse cycles. A pulse tube 26 is installed inside the dust collector housing 1, with its top end penetrating the housing 1 and connecting to the pulse valve 2. The pulse valve 2 and pulse tube 26 work together to use compressed air to back-flush and clean the filter bags 19, effectively preventing filter bag clogging, improving dust collection efficiency, and reducing filter bag wear. A sealing panel 6 is located on the front of the dust collector housing 1, with one side of a sliding plate 18 connected to the back of the sealing panel 6. An observation window 10 is located on the outer surface of the ash collection hopper 11, and a discharge valve 9 is fixedly connected to the bottom of the ash collection hopper 11. The shell 1 adopts a sealed panel 6 design for easy maintenance and cleaning. The dust collection hopper 11 is equipped with an observation window 10 and a dust discharge valve 9. The dust collector shell 1 is internally fixedly connected to a guide plate 20, which can redirect the airflow into the dust collection hopper 11. At the same time, the airflow speed is slowed down. Due to inertia, coarse dust particles in the gas flow directly into the dust collection hopper 11. The observation window 10 facilitates real-time monitoring of dust accumulation and timely dust discharge. The bottom surface of the dust collector shell 1 is fixedly connected to two sets of support legs 13. The bottom end of each set of support legs 13 is fixedly connected to a fixed seat 8. The upper surface of each fixed seat 8 is provided with a fixing hole 12. A controller 7 is installed on the outer surface of one of the support legs 13. The support legs 13 and the fixed seat 8 provide stable support to ensure stable operation of the equipment in high-speed airflow and vibration environments, making it suitable for complex working conditions in feed production workshops.

[0024] The working principle of this utility model is as follows: In use, the pulse dust collector is first installed in the operating position via support legs 13 and a fixed base 8. The power supply to the pulse dust collector is then connected, causing the pulse valve 2 to connect to the high-pressure air source. The controller 7 starts the pulse dust collector. Air from inside the feed production workshop enters the dust collector housing 1 through the air inlet pipe 5. A guide vane 20 is installed at the air inlet 21, causing the airflow to turn and flow into the dust collection hopper. Simultaneously, the airflow speed slows down. Due to inertia, coarse dust particles in the gas flow directly into the dust collection hopper 11, while fine dust particles... The dust is filtered through the filter bag 19. After running for a period of time, the controller 7 controls the pulse valve 2 to open, and with the cooperation of the pulse tube 26, high-pressure gas is blown into the filter bag 19, causing the dust on the outside of the filter bag 19 to fall into the dust collection hopper 11. When replacing the filter bag 19, the drive motor 3 drives the lead screw 24 to rotate, causing the sliding plate 18 to move along the guide rail 17, which can quickly pull the filter bag 19 out of the dust collector housing 1 without disassembling the entire dust collector, greatly improving the replacement efficiency and reducing maintenance costs.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
