Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a cyclone dust collector for fertilizer production. Background Technology

[0002] The production and processing of fertilizers generates a large amount of dust. This dust floats in the production area and can affect the health of production workers and operators. Therefore, cyclone dust collectors are needed to remove dust from the air.

[0003] Patent CN218530286U discloses a cyclone dust collector for producing ceramic tiles, including a cone-shaped dust collector. The inner wall of the cone-shaped dust collector is equipped with a noise reduction mechanism. A treatment chamber is installed at the upper end of the cone-shaped dust collector through a first connecting pipe. One end of the treatment chamber is connected to an exhaust pump, and the other end of the treatment chamber is connected to an air inlet through a second connecting pipe. The air inlet is located at one end of the cone-shaped dust collector. A dust collection box is installed at the lower end of the cone-shaped dust collector. A cyclone separator is installed inside the cone-shaped dust collector, and a spray head is installed on the inner wall of the cone-shaped dust collector through a universal joint.

[0004] In the above case, the dust was collected by cyclone dust suppression through a cone, with dust collected in a dust collection box at the bottom and the dust filtration aided by a treatment chamber and filter screen at the top. However, when the airflow passed through the cone, it was easy to stir up the dust in the dust collection box again, which affected the dust removal effect of the dust collector and made it inconvenient to disassemble and clean the filter screen in the treatment chamber. Utility Model Content

[0005] The purpose of this utility model is to provide a cyclone dust collector for fertilizer production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cyclone dust collector for fertilizer production, comprising a dust collection tank for dust removal in fertilizer production, an inner air duct fixedly connected to the top of the inner cavity of the dust collection tank, the top of the inner air duct extending through the dust collection tank and fixedly connected to a top pipe, a cyclone plate fixedly connected to the outer side of the inner air duct inside the dust collection tank, a filter assembly slidably connected to the inner side of the top pipe, a dust box fixedly connected to the bottom of the dust collection tank, a flow guide assembly fixedly connected to the inner side of the dust box, and an air inlet pipe fixedly connected to one side of the top of the dust collection tank.

[0007] In a preferred embodiment, the flow diversion assembly includes a one-way ring fixedly connected to the top of the inner side of the dust box, and a baffle plate fixedly connected to the top of the one-way ring, the top of which extends into the interior of the dust collection tank.

[0008] In a preferred embodiment, the upper half of the unidirectional ring has a smaller diameter component, while the diameter of the windbreak gradually increases upwards.

[0009] In a preferred embodiment, the filter assembly includes a retainer slidably connected to the inside of the top tube, a guide plate fixedly connected to the bottom end of the inner side of the retainer, an outer ring fixedly connected to the top of the guide plate, and a pull ring fixedly connected to the outer side of the retainer.

[0010] In a preferred embodiment, the inner side of the guide plate protrudes upward, the outer edge of the top of the outer ring extends to the outer side, and the top of the card holder is threadedly connected to a threaded sleeve.

[0011] In a preferred embodiment, a filter plate is fixedly connected to the inner side of the threaded sleeve, and a bottom protrusion is fixedly connected to the inner side of the filter plate. The bottom of the bottom protrusion is arc-shaped and its diameter is larger than the top of the outer ring.

[0012] In a preferred embodiment, a bracket is fixedly connected to the outside of the dust collection tank, a discharge pipe is fixedly connected to the bottom of the dust box, and a valve is fixedly connected to the outside of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention, by setting up a flow-guiding component, ensures that when the gas flows to the bottom of the dust collector, most of the gas is blocked by the baffle and guided into the inner air duct. The dust discharged by the centrifugal force will slide down into the dust box through the gap between the inner wall of the dust collector and the outer side of the baffle. Then, guided by the one-way ring, it falls to the bottom of the dust box. The obstruction at the bottom of the one-way ring makes it difficult for the dust entering the bottom of the dust box to be stirred up, thus improving the dust removal effect of the dust collector.

[0014] This utility model, by setting up a filter assembly, an internal air duct, and a cyclone plate, allows the internal air duct to separate downward and upward airflows. The cyclone plate guides the rotation of the downward airflow, further improving the dust collection effect of the dust collector. The cooperation of the mounting bracket and threaded sleeve facilitates the disassembly and cleaning of the filter plate. The cooperation of the outer ring and bottom protrusion ensures that the dust blocked by the filter plate falls above the guide plate and does not fall back into the dust collection tank, thus ensuring the working efficiency of the dust collector.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figures 1-4 This utility model provides a cyclone dust collector for fertilizer production, including a dust collection tank 1 for dust removal in fertilizer production. An inner air duct 2 is fixedly connected to the top of the inner cavity of the dust collection tank 1. A cyclone plate 4 is fixedly connected to the outer side of the inner air duct 2 inside the dust collection tank 1. A dust box 11 is fixedly connected to the bottom of the dust collection tank 1. A flow guide component is fixedly connected to the inner side of the dust box 11. An air inlet pipe 15 is fixedly connected to one side of the top of the dust collection tank 1. The flow guide component includes a one-way ring 13 fixedly connected to the top of the inner side of the dust box 11. A baffle 12 is fixedly connected to the top of the one-way ring 13, and its top extends into the interior of the dust collection tank 1. The diameter of the upper half of the one-way ring 13 decreases upward, while the diameter of the baffle 12 gradually increases upward. A bracket 16 is fixedly connected to the outer side of the dust collection tank 1. A discharge pipe 14 is fixedly connected to the bottom of the dust box 11. A valve is fixedly connected to the outer side of the discharge pipe 14.

[0020] Dust-laden gas generated during fertilizer production enters the top of the dust collector 1 through the inlet pipe 15. It contacts the inner wall of the dust collector 1 and forms a downward spiral airflow guided by the cyclone plate 4. Due to the rotation of the gas, the dust particles inside are subjected to centrifugal force and are thrown towards the outer wall of the dust collector 1, achieving separation. When the gas flows to the bottom of the dust collector 1, it is blocked by the baffle 12, causing it to flow into the inner air duct 2 and flow upward. The dust slides down along the gap between the dust collector 1 and the baffle 12 and falls to the bottom of the dust box 11 through the one-way ring 13.

[0021] When the gas flows to the bottom of the dust collector 1, the baffle 12 blocks most of the gas, preventing it from directly impacting the dust box 11. Instead, the gas is guided into the inner duct 2, reducing the disturbance of the dust particles inside the dust box 11. The one-way ring 13 further guides the dust particles to fall to the bottom of the dust box 11, and the structure at the bottom of the one-way ring 13 prevents the dust particles from being lifted up again by the airflow. This design ensures that the dust particles can be stably deposited at the bottom of the dust box 11, reducing secondary dust re-entrainment and further improving the dust removal effect of the dust collector.

[0022] Please see Figures 1-4 The top of the inner air duct 2 extends through the dust collector 1 and is fixedly connected to the top pipe 3. A filter assembly is slidably connected to the inside of the top pipe 3. The filter assembly includes a bracket 5 slidably connected to the inside of the top pipe 3. A guide plate 6 is fixedly connected to the bottom of the inside of the bracket 5. An outer ring 7 is fixedly connected to the top of the guide plate 6. A pull ring is fixedly connected to the outside of the bracket 5. The inside of the guide plate 6 protrudes upward. The top of the outer ring 7 extends outward. A threaded sleeve 8 is threadedly connected to the top of the bracket 5. A filter plate 9 is fixedly connected to the inside of the threaded sleeve 8. A bottom protrusion 10 is fixedly connected to the inside of the filter plate 9. The bottom of the bottom protrusion 10 is arc-shaped and its diameter is larger than the top of the outer ring 7.

[0023] After the gas enters the inner duct 2, it flows into the top pipe 3 and passes through the guide plate 6 and the filter plate 9. Finally, it exits the top pipe 3. The filter plate 9 filters the remaining dust inside the gas. The isolated dust falls above the guide plate 6 and is blocked by the outer ring 7 to prevent it from falling back into the dust collector 1. The discharge pipe 14 can be opened through the valve to discharge the dust in the dust box 11.

[0024] The inner duct 2 separates the descending and ascending airflows, allowing the dust-laden gas to form an orderly airflow after entering the dust collector 1. This design helps improve the stability and separation efficiency of the airflow. The cyclone plate 4 guides the rotation of the descending airflow. The mounting bracket 5 is slidably connected to the inside of the top pipe 3, and the threaded sleeve 8 is threadedly connected to the top of the mounting bracket 5, making it easy to install and remove the filter plate 9, thus improving the service life of the dust collector. The cooperation between the outer ring 7 and the bottom protrusion 10 ensures that the dust blocked by the filter plate 9 falls above the guide plate 6 instead of falling back into the dust collector 1, preventing dust backflow and ensuring the working efficiency of the dust collector.

[0025] The working principle and usage process of this utility model: The dust-laden gas generated in fertilizer production enters the top of the dust collector 1 through the inlet pipe 15. It contacts the inner wall of the dust collector 1 and forms a downward spiral airflow through the cyclone plate 4. Due to the rotation of the gas, the dust particles inside are subjected to centrifugal force and are thrown to the outer wall of the dust collector 1, achieving separation. When the gas flows to the bottom of the dust collector 1, it is blocked by the baffle 12, causing it to flow into the inner air duct 2 and flow upward. The dust slides down along the gap between the dust collector 1 and the baffle 12 and falls to the bottom of the dust box 11 through the one-way ring 13. After the gas enters the inner air duct 2, it flows into the top pipe 3 and passes through the guide plate 6 and the filter plate 9, and finally exits from the top pipe 3. The filter plate 9 filters the remaining dust inside the gas. The isolated dust falls above the guide plate 6 and is blocked by the outer ring 7 to prevent it from falling back into the dust collector 1. The discharge pipe 14 can be opened through the valve to discharge the dust in the dust box 11.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
