Description

Technical Field

[0001] This utility model relates to the technical field of cyclone dust removal devices, specifically a cyclone dust removal device for fuel rod production. Background Technology

[0002] Cyclone dust collectors are a type of dust removal device. Their dust removal mechanism involves rotating the dust-laden airflow, using centrifugal force to separate dust particles from the airflow and collect them on the collector wall. Gravity then causes the dust particles to fall into the dust hopper. However, existing cyclone dust collectors have some shortcomings, such as:

[0003] The cyclone dust collector described in application number CN201410289740.1 has an integrated structure. During use, due to different working environments, the generated flue gas dust will continuously adhere to the inner wall of the equipment over time. When it reaches a certain thickness, it will affect the air volume and cause the risk of blockage. Utility Model Content

The bottom cylinder has a conical structure and a U-shaped groove is opened on the side of the bottom cylinder. A circular hole is opened at the connection position between the groove on the side of the bottom cylinder and the support frame.

[0008] Using the above technical solution, the device slides the bottom cylinder onto the support frame. Its structure is simple and easy to install. The conical structure of the bottom cylinder can better facilitate dust collection, and the U-shaped groove on the side of the bottom cylinder can provide a force point during installation, making it easy to fix.

The motor is fixedly connected to the upper surface of the vortex tube, and the motor can provide pressure to the vent cover to ensure the sealing of the device.

[0015] As a preferred technical solution of this utility model, the lower output end of the motor is fixedly connected to the turbofan, and a cleaning scraper is fixedly connected to the center position below the turbofan. The cleaning scraper has eight petals.

[0016] By adopting the above technical solution, the cleaning scraper is fixedly connected to the center position below the turbofan, which can make the cleaning scraper and the turbofan coaxial, reducing power waste.

[0017] As a preferred technical solution of this utility model, the side of the vent cover is provided with a U-shaped groove that is the same as the bottom cylinder structure. The bottom cylinder and the outer side of the vent cover are fitted with screws, and the screws pass through the support frame. The screws are installed with bolts.

[0018] Using the above technical solution, the equipment connects the vent cover to the bottom cylinder and the support frame through the through-hole of the screw, forming an overall structure from top to bottom. This not only simplifies the structure but also ensures the sealing of the equipment.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This device uses a sliding placement method to install the bottom cylinder on top of the support frame. Its structure is simple and easy to install.

[0035] Please see Figure 1 - Figure 6 The present invention provides a cyclone dust removal device for fuel rod production, comprising a support frame 1, a bottom cylinder 2, a dust collection cylinder 3, a dust inlet pipe 4, a motor 5, an air outlet 6, a vortex pipe 7, a ventilation cover 8, a screw 9, a cleaning scraper 10, a turbine fan 11, and a negative pressure suction pipe 12.

[0036] A base cylinder 2 is mounted on top of the support frame 1, and is slidably connected to the support frame 1. The base cylinder 2 has a conical structure and a U-shaped groove on its side. A circular hole is provided at the connection point between the groove on the side of the base cylinder 2 and the support frame 1. This device is installed on top of the support frame 1 by sliding, which is simple in structure and easy to install. The conical structure of the base cylinder 2 facilitates dust collection, and the U-shaped groove on its side provides a stress point during installation, making it easy to fix. A screw 9, a dust collection cylinder 3, and a dust inlet pipe 4 are mounted on top of the base cylinder 2. Four support legs are fixedly connected to the bottom of the support frame 1, and there are eight support legs at the bottom of the support frame 1. The device features a figure-eight structure with four evenly distributed screws 9 on top of the support frame 1. The support frame 1 is constructed from support legs with a figure-eight shape, maximizing the stress points and lowering the overall center of gravity to ensure operational stability. The four evenly distributed screws 9 on top of the support frame 1 act as limiters, preventing misalignment between the support frame 1 and the bottom cylinder 2. The dust collection cylinder 3 is equipped with a vent cover 8, an air outlet 6, a vortex pipe 7, and a negative pressure suction pipe 12. The dust collection cylinder 3 is slidably connected to the bottom cylinder 2. A dust inlet pipe 4 is fixedly connected to the left side of the dust collection cylinder 3, and a vent cover 8 is fitted over the dust inlet pipe 4. The negative pressure suction pipe 12 is fixedly connected to the center of the vent cover 8. 2. This device, by mounting a vent cover 8 above the dust inlet pipe 4, can be configured as a separate component, effectively improving the ease of installation. A motor 5 and a turbo fan 11 are mounted above the vent cover 8. A vortex tube 7 is fixedly connected above the vent cover 8, and an air outlet 6 is fixedly connected to the right side of the vortex tube 7. The motor 5 is fixedly connected to the upper surface of the vortex tube 7. By placing the dust inlet pipe 4 on the left and the air outlet 6 on the right, this device improves its distinguishability and facilitates pipe connections. The motor 5, fixedly connected to the upper surface of the vortex tube 7, provides pressure to the vent cover 8 to ensure the device's sealing. A cleaning scraper 10 is located below the motor 5. The output end is fixedly connected to the turbofan 11. The cleaning scraper 10 is fixedly connected to the center position below the turbofan 11. The cleaning scraper 10 has eight segments. By fixing the cleaning scraper 10 to the center position below the turbofan 11, the cleaning scraper 10 and the turbofan 11 can be coaxial, reducing power waste. The side of the vent cover 8 has a U-shaped groove with the same structure as the bottom cylinder 2. The bottom cylinder 2 and the outer side of the vent cover 8 are fitted with screws 9, and the screws 9 pass through the support frame 1. The screws 9 are fitted with bolts. The device connects the vent cover 8, the bottom cylinder 2 and the support frame 1 through the through-hole of the screws 9, forming an integrated structure from top to bottom. It is not only simple in structure, but also ensures the sealing of the equipment.

[0037] Working principle: When using a cyclone dust collector for fuel rod production, first place the support frame 1 in a suitable position, then insert the bottom cylinder 2 above the support frame 1, and put the dust collection cylinder 3 on top of the bottom cylinder 2. Then, install the vent cover plate 8 on top of the dust collection cylinder 3. Pass the screw 9 from top to bottom through the vent cover plate 8 through the bottom cylinder 2 and the support frame 1, and fix it with bolts. Then connect various pipelines and dust collection components to start the equipment. When the equipment is running, the high-speed rotating turbine fan 11 will rotate together with the cleaning scraper 10, generating negative pressure and scraping off the dust attached to the inner wall of the equipment to prevent blockage.
