Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal device for formaldehyde production. Background Technology

[0002] In the chemical production field, formaldehyde, as an important organic chemical raw material, is widely used in many industries such as synthetic resins, plastics, coatings, and dyes. However, the production process of formaldehyde is often accompanied by complex physical and chemical reactions. If the dust-containing gases generated during this process are directly emitted without effective treatment, they will not only cause serious pollution to the production environment but also affect product quality and even endanger the health of operators. Therefore, the development of efficient dust removal equipment for formaldehyde production is of great practical significance.

[0003] A dust removal device for formaldehyde production, with announcement number CN216572100U, relates to the field of chemical production equipment technology. It includes a dust collection box and a filter plate. A connecting pipe is fixed to the side wall of the dust collection box. A sealing block is fixed to the top of the filter plate, and a handle is fixed to the top of the sealing block. A support plate is fixed to the top of the dust collection box, and a limiting mechanism is provided on the support plate. The limiting mechanism includes a first spring, one side of which is fixed to the support plate, and the side of the first spring away from the support plate is fixed to the limiting block. When disassembling the filter plate, pressing two sets of push plates, through the cooperation of push rods, racks, gears, and locking teeth, moves the limiting block away from the top of the sealing block. Then, because the second spring is compressed, the filter plate moves upward, and the filter plate can be removed from the dust collection box via the handle.

[0004] The existing technology described above uses multiple filter screens for dust removal, which is a single method with limited filtration accuracy and reduced filtration efficiency. Furthermore, the arrangement of multiple filter screens increases airflow resistance, thereby affecting the overall dust removal efficiency. After use, the filter screens lack self-cleaning capabilities and require manual removal of each screen, which is cumbersome and increases labor costs. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal device for formaldehyde production, so as to solve the problems mentioned in the background art, such as the single dust removal method of existing dust removal devices for formaldehyde production, the need to frequently replace multiple filter elements, and the cumbersome operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for formaldehyde production, comprising a dust removal box and an airflow pipe, wherein both ends of the dust removal box are connected to the airflow pipe, the left end is the air inlet end and the right end is the air outlet end;

[0007] The dust collector is connected to a trapezoidal housing on the outside, and a transmission mechanism is installed inside the trapezoidal housing. An airflow distribution plate is connected to one side of the dust collector. Electrostatic dust collection plates are evenly connected inside the dust collector on one side of the airflow distribution plate, and a filter screen is connected inside the dust collector on the other side of the electrostatic dust collection plate. A dust collection box is connected to the bottom of the dust collector, and side blocks are fixed on both sides of the dust collection box. A docking hole is opened on one side of each side block. A fixing component is provided between the dust collection box and the dust collector.

[0008] Furthermore, the bottom of the dust collection box is provided with a flow channel, and the flow channel is interconnected with the dust collection box, wherein the top of the dust collection box is open.

[0009] Furthermore, the fixing component includes fixing blocks fixed to both sides of the bottom of the dust collector, and each fixing block is connected to a telescopic elastic element. One end of each telescopic elastic element is connected to a pull plate, and one end of each pull plate is connected to an insertion block. One end of each insertion block extends into the mating hole.

[0010] Furthermore, an electrostatic generator is connected to one side of the top of the dust collection box, and three electrostatic dust collection plates are arranged inside the dust collection box in an alternating pattern.

[0011] Furthermore, the transmission mechanism includes a drive motor, which is fixed to the outside of the trapezoidal housing via a support plate. The output shaft of the drive motor is connected to a main shaft, and a drive shaft and a driven shaft are respectively connected to the two sides of the inside of the trapezoidal housing below the main shaft. A belt drive assembly is connected between the drive shaft, the driven shaft, and the main shaft. A turntable is sleeved on one end of the outer side of the main shaft, and a connecting column is fixed on the outer side of the turntable. A forward and reverse rotation assembly is connected to one end of the connecting column.

[0012] Furthermore, the belt drive assembly includes three pulleys and a drive belt. The pulleys are respectively fitted onto the main shaft, the drive shaft, and the driven shaft, and the drive belt connects the pulleys.

[0013] Furthermore, the forward and reverse rotation assembly includes a movable part sleeved on the connecting column, and one end of the movable part is connected to a power gear plate. The top of the power gear plate is engaged with a transmission gear. A connecting shaft is fixedly inserted through the transmission gear, and one end of the connecting shaft extends into the dust collector and is connected to a connecting rod. One end of the connecting rod is connected to a striking ball, and the bottom end of the power gear plate is connected to a guide post, which is located inside the trapezoidal housing.

[0014] Furthermore, both the drive shaft and the driven shaft extend into the dust collection box and are fixedly fitted with impact protrusions, which are distributed between the electrostatic dust collection plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the dust removal equipment for formaldehyde production not only has a high-efficiency dust removal effect, but also has an anti-clogging effect, avoiding frequent replacement of dust removal components;

[0016] By using multiple electrostatic dust collection plates and filter plates, multi-stage high-efficiency dust removal can be achieved. In this process, the airflow distribution plate and multiple opposite turbulent flow guiding ridges are used to achieve uniform airflow distribution, avoiding local airflow velocities that are too high or too low. This allows the airflow to pass evenly through the electrostatic dust collection plates, replacing a single filter plate and improving dust removal efficiency, thereby improving the quality of formaldehyde production.

[0017] After the electrostatic dust collection plates and filter plates are used for dust removal, the electrostatic generator is turned off. The transmission mechanism provides driving force to make the two impact protrusions rotate, which intermittently impacts multiple electrostatic dust collection plates, causing them to shake and causing the dust adsorbed on the electrostatic dust collection plates to fall off. This ensures the continuity and efficiency of electrostatic dust collection, reduces manual operation, and saves labor costs.

[0018] During the cleaning process of the electrostatic dust collection plate, the power toothed plate seat reciprocates horizontally and meshes with the transmission gear, causing the connecting shaft to rotate in both directions. This causes the connecting rod and the striking ball to swing left and right in the dust collection box, which in turn knocks the filter screen and electrostatic dust collection plate apart, knocking off the powder cake left on the filter screen to prevent clogging. This allows for long-term filtration and dust removal without the need for frequent replacement and cleaning of filter components, thereby improving the working efficiency of the equipment.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0028] To address the issues of low dust removal efficiency and inconvenient cleaning in existing dust removal equipment used in formaldehyde production, the following technical solution is disclosed: a dust removal device for formaldehyde production, comprising a dust collection box 1 and an airflow pipe 4. Both ends of the dust collection box 1 are connected to the airflow pipe 4, with the left end being the air inlet and the right end the air outlet. A trapezoidal housing 5 is connected to the outside of the dust collection box 1, and a transmission mechanism 7 is installed inside the trapezoidal housing 5. The transmission mechanism 7 includes a drive motor 707, which is fixed to the outside of the trapezoidal housing 5 by a support plate. The output shaft of the drive motor 707 is connected to a main shaft 701. A drive shaft 703 and a driven shaft 704 are respectively connected to the two sides of the trapezoidal housing 5 below the main shaft 701. A belt drive assembly 705 connects the drive shaft 703, the driven shaft 704, and the main shaft 701. A turntable 702 is sleeved on one side, and a connecting post 706 is fixed on the outside of the turntable 702. The belt drive assembly 705 includes three pulleys and a drive belt. The pulleys are respectively sleeved on the main shaft 701, the drive shaft 703 and the driven shaft 704. The drive belt is connected between the pulleys. One end of the drive shaft 703 and the driven shaft 704 extends into the dust collection box 1 and is fixedly sleeved with an impact protrusion 15. The impact protrusion 15 is distributed between the electrostatic dust collection plates 14. An airflow distribution plate 8 is connected to one side of the dust collection box 1. Electrostatic dust collection plates 14 are evenly connected inside the dust collection box 1 on one side of the airflow distribution plate 8. A filter screen plate 13 is connected inside the dust collection box 1 on one side of the electrostatic dust collection plate 14. An electrostatic generator 6 is connected to one side of the top of the dust collection box 1. Three electrostatic dust collection plates 14 are provided inside the dust collection box 1 and are staggered.

[0029] Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 5 In this embodiment, during the formaldehyde production process, the air enters the dust collection box 1 through the airflow pipe 4 and passes through the airflow distribution plate 8, causing the airflow to flow evenly from multiple directions through multiple turbulent flow guide ridges 801. Then, the electrostatic generator 6 is used to start the electrostatic dust collection plate 14, which adsorbs dust and other impurities in the air. The electrostatic dust collection plate 14 is set with multiple plates in an alternating distribution to ensure comprehensive dust adsorption. The airflow continues to flow and passes through the filter plate 13 for further filtration, leaving particulate impurities in the air in the dust collection box 1. The filtered airflow is discharged from the airflow pipe 4. Later, the electrostatic generator 6 is turned off and the drive motor 707 is started to drive the main shaft 701 to rotate. With the help of the belt drive assembly 705, the drive shaft 703 and the driven shaft 704 rotate synchronously, which in turn drives the two impact protrusions 15 to rotate, intermittently impacting the electrostatic dust collection plate 14, causing the dust attached to the electrostatic dust collection plate 14 to fall off and into the dust collection box 2.

[0030] One end of the connecting column 706 is connected to a forward and reverse rotation assembly. The forward and reverse rotation assembly includes a movable part sleeved on the connecting column 706, and one end of the movable part is connected to a power gear plate 9. The top of the power gear plate 9 is meshed with a transmission gear 10. A connecting shaft 11 is fixedly passed through the transmission gear 10, and one end of the connecting shaft 11 extends into the dust collector box 1 and is connected to a connecting rod 12. One end of the connecting rod 12 is connected to a striking ball 1201. The bottom end of the power gear plate 9 is connected to a guide column 901, and the guide column 901 is located inside the trapezoidal housing 5.

[0031] Please refer to the details. Figure 1 , Figure 2 During the rotation of the main shaft 701, the turntable 702 rotates synchronously. During the rotation of the turntable 702, it works with the connecting column 706 to make the power gear plate 9 move back and forth, and uses the guide column 901 for limiting and guiding. The power gear plate 9 meshes with the transmission gear 10, which in turn makes the transmission gear 10 and the connecting shaft 11 rotate in both directions, and drives the connecting rod 12 and the striking ball 1201 to rotate synchronously. That is, the connecting rod 12 swings left and right in the dust collection box 1. The striking ball 1201 impacts the filter screen 13 and the electrostatic dust collection plate 14 to generate power, which then shakes off the dust and impurities left on the filter screen 13, achieving convenient cleaning. Example 2

[0032] This embodiment differs from Embodiment 1. By utilizing the dust collection box 2, the dust generated during shaking and cleaning can be collected and centrally processed, avoiding frequent replacement of the electrostatic dust suction plate 14 and the filter screen 13. Therefore, the following technical solution is disclosed: The bottom of the dust collection box 1 is connected to the dust collection box 2, and side blocks 201 are fixed on both sides of the dust collection box 2. A flow channel is provided at the bottom of the dust collection box 1, and the flow channel is interconnected with the dust collection box 2. The top of the dust collection box 2 is open, and a docking hole 202 is provided on one side of each side block 201. A fixing component is provided between the dust collection box 2 and the dust collection box 1. The fixing component includes fixing blocks 3 fixed to both sides of the bottom of the dust collection box 1, and each fixing block 3 is connected to a telescopic elastic member 301. One end of each telescopic elastic member 301 is connected to a pull plate 302, and one end of each pull plate 302 is connected to an insertion block 303. One end of each insertion block 303 extends into the docking hole 202.

[0033] Please refer to the details. Figure 1 , Figure 2 , Figure 4In this embodiment, the dust collection box 2 is aligned with the flow channel at the bottom of the dust removal box 1. Even if the dust collection box 2 is stuck between the two fixed blocks 3, the pull plate 302 is pulled, which drives the insertion block 303 to move horizontally and compresses the telescopic elastic member 301. Then, under the elastic reset action of the telescopic elastic member 301, the insertion block 303 is pushed into the docking hole 202, and the dust collection box 2 is installed at the bottom of the dust removal box 1. This allows the collection of particulate impurities and dust cleaned by the electrostatic dust collection plate 14 and the filter screen 13. Later, the dust collection box 2 can be removed by disengaging the insertion block 303 from the docking hole 202. This achieves centralized treatment of impurities and eliminates the need for frequent replacement and cleaning of the filter screen 13 and the electrostatic dust collection plate 14, thus improving the working efficiency of the equipment.
