A dust treatment device for corrugated paper production

Abstract

This utility model relates to the field of dust treatment technology and discloses a dust treatment device for corrugated paper production. The device includes a first support and a second support. A bag filter is fixedly installed inside the second support, and dust removal components are installed on both the first and second supports. By activating the dust removal components, dust from the corrugated paper production site is drawn into the dust inlet hood along with the air through a rectangular filter plate when the suction fan at the top of the first support is activated and the auxiliary fan on the second support is activated. The dust then passes through an auxiliary pipe, a corrugated metal pipe, a dust inlet pipe, and a first connecting pipe into a sorting cylinder. An open solenoid valve allows impurities to fall into a collection box, while smaller dust particles enter the bag filter through the second connecting pipe, where they are collected. The filtered gas is discharged through a third connecting pipe and the auxiliary fan, thus improving the treatment of collected dust.

Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, specifically a dust treatment device for corrugated paper production. Background Technology

[0002] Corrugated paper is a common material used in paper packaging boxes. It is lightweight, rigid, and easy to cut to size, which can effectively protect the packaged products. It is widely used in the packaging industry. From the perspective of production process, corrugated paper is generally made by bonding linerboard and corrugated paper that has been processed into a wave shape by corrugating rollers. Dust is generated in processes such as pulping, mechanical processing of corrugation, and bonding. For example, in the pulping stage, the crushing of raw materials will cause fine fibers to be dispersed into the air.

[0003] These dust particles not only affect the cleanliness of the production environment, but also pose a threat to the health of workers. Long-term exposure to high dust levels can easily lead to respiratory diseases such as pneumoconiosis. During the production process, excessive dust may adhere to critical components of the equipment, such as transmission devices and heating elements, thereby accelerating equipment wear, reducing equipment lifespan, and increasing equipment maintenance costs.

[0004] Currently, there are various dust removal devices for corrugated paper production on the market. Some devices use electrostatic dust removal, which attempts to remove dust using electrostatic dust removal rods. However, the actual application effect is not good. Electrostatic dust removal is difficult to remove dust from all directions, which affects the overall quality of corrugated cardboard. It is not possible to effectively remove dust and sort dust and impurities through a device with adjustable suction port orientation. The overall practicality of the device needs to be improved. In view of this, we propose a dust treatment device for corrugated paper production. Utility Model Content

[0005] The purpose of this invention is to provide a dust treatment device for corrugated paper 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 dust treatment device for corrugated paper production includes a first support and a second support. A bag filter is fixedly installed inside the second support. Dust collection components are provided on the first and second supports. The dust collection components include: A suction fan is fixedly installed on the top of the first bracket. The input end of the suction fan is fixedly connected to one end of the dust inlet pipe, and the other end of the dust inlet pipe is fixedly connected to one end of the metal corrugated pipe. An auxiliary pipe is fixedly installed on the other end of the metal corrugated pipe, and a small end of the dust inlet hood is fixedly installed on the other end of the auxiliary pipe. A rectangular filter plate is attached to the large end of the dust inlet hood. A sorting cylinder is fixedly installed inside the first bracket. A first connecting pipe is fixedly installed between the input end of the sorting cylinder and the output end of the suction fan. A second connecting pipe is fixedly installed between the input end of the bag filter and the output end of the sorting cylinder. The sorting cylinder is equipped with a solenoid valve at its bottom end, and a collection box is threaded onto the bottom of the sorting cylinder. An auxiliary fan is fixedly installed inside the bottom end of the second bracket, and a third connecting pipe is fixedly installed between the input end of the auxiliary fan and the output end of the bag filter.

[0007] In a further embodiment, the dust inlet hood is cone-shaped to better draw in dust.

[0008] In a further embodiment, the bag filter includes valves and a collection unit located at its bottom for better dust collection.

[0009] In a further embodiment, an auxiliary component is provided on the outside of the second support. The auxiliary component includes a circular strip. The circular strip is fixedly installed on the outside of the rectangular filter plate, and a through groove is formed on the circular strip.

[0010] In a further embodiment, multiple sets of circular strips are provided, and the centers of the circular cross-sections of the multiple sets of circular strips are coaxial. Multiple sets of through grooves are provided on a single set of circular strips, which can prevent sheet materials from being sucked up and directly attached to the outside of the rectangular filter plate, thus preventing dust from being sucked away.

[0011] In a further embodiment, the first connecting pipe is fixedly installed with a bent pipe top end at one end inside the sorting cylinder, and a conical cover top small end is fixedly installed at the bottom end of the bent pipe.

[0012] In a further embodiment, a circular filter plate is fixedly installed inside the top of the sorting cylinder. The circular filter plate is located directly above the curved pipe. The inner diameter of the filter holes on the circular filter plate is smaller than that on the rectangular filter plate, thus better removing large particulate impurities from the dust.

[0013] Compared with the prior art, this utility model provides a dust treatment device for corrugated paper production, which has the following beneficial effects: 1. This dust treatment device for corrugated paper production, in order to better handle the collected dust, is equipped with a dust removal component. When the suction fan at the top of the first support and the auxiliary fan on the second support are started, the dust at the corrugated paper production point enters the dust inlet hood along with the air through the rectangular filter plate. Then, it enters the sorting cylinder through the auxiliary pipe, the metal corrugated pipe, the dust inlet pipe and the first connecting pipe. The solenoid valve is opened, allowing impurities to fall downward into the collection box. The smaller dust particles enter the bag filter through the second connecting pipe, thus the dust is collected. The filtered gas is discharged through the third connecting pipe and the auxiliary fan, thereby better handling the collected dust.

[0014] 2. To improve the practicality of this dust treatment device for corrugated paper production, auxiliary components are incorporated. When the dust removal components are working, the circular strips prevent sheet-like materials from being sucked up and directly adhering to the outside of the rectangular filter plate, thus preventing dust from being removed. The through-channel allows dust to enter the dust inlet hood normally. Combined with the curved pipe's bottom opening facing the collection box and the conical structure of the conical hood (smaller at the top and larger at the bottom), impurities fall more effectively into the collection box, while smaller dust particles are sucked upwards into the second connecting pipe. The circular filter plate further intercepts impurities, thereby achieving the separation of impurities and dust and improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0019] Please see Figures 1-6 This utility model provides a technical solution: A dust treatment device for corrugated paper production includes a first support 1 and a second support 2, wherein a bag filter 39 is fixedly installed inside the second support 2.

[0020] In one embodiment of this utility model, a dust removal assembly 3 is provided on the first support 1 and the second support 2. The dust removal assembly 3 includes a suction fan 31. The suction fan 31 is fixedly installed on the top of the first support 1. The input end of the suction fan 31 is fixedly connected to one end of the dust inlet pipe 32. The other end of the dust inlet pipe 32 is fixedly connected to one end of the metal corrugated pipe 33. An auxiliary pipe 34 is fixedly installed on one end of the metal corrugated pipe 33. The small end of the dust inlet hood 35 is fixedly installed on the other end of the auxiliary pipe 34. In addition, the dust inlet hood 35 is conical in shape to better suck up dust. A rectangular filter plate 36 is snapped onto the large end of the dust inlet hood 35. A sorting cylinder 37 is fixedly installed inside the first support 1. The input end of the sorting cylinder 37 is connected to the input end of the suction fan 31. A first connecting pipe 38 is fixedly installed between the output ends. A second connecting pipe 310 is fixedly installed between the input end of the bag filter 39 and the output end of the sorting cylinder 37. In addition, the bag filter 39 includes valves and collection components at its bottom end for better dust collection. It is worth noting that the air blowing components, bag components, and supports inside the bag filter 39 are all existing structures of existing bag filter dust collectors, so they will not be described in detail. A solenoid valve 311 is provided at the bottom end of the sorting cylinder 37. A collection box 312 is threadedly installed at the bottom of the sorting cylinder 37. An auxiliary fan 313 is fixedly installed inside the bottom end of the second support 2. A third connecting pipe 314 is fixedly installed between the input end of the auxiliary fan 313 and the output end of the bag filter 39.

[0021] In this embodiment, when the suction fan 31 at the top of the first support 1 and the auxiliary fan 313 on the second support 2 are started, the suction fan 31 begins to operate and generates suction, creating a negative pressure environment in the area of ​​the dust inlet hood 35. Dust generated at the corrugated paper production point, facing the larger end of the dust inlet hood 35, is drawn through the rectangular filter plate 36, which is attached to the larger end of the dust inlet hood 35, under the negative pressure. The rectangular filter plate 36 acts as a preliminary filter, intercepting larger particles of impurities and allowing dust and air to pass through into the interior of the dust inlet hood 35. Because the dust inlet hood 35 is conical, this structure effectively guides the airflow, allowing dust to be drawn in more smoothly and improving dust collection efficiency. The dust and air mixed together inside the dust inlet hood 35 are then transported sequentially through the auxiliary pipe 34, the corrugated metal pipe 33, the dust inlet pipe 32, and the first connecting pipe 38. The corrugated metal pipe 33 has a certain degree of flexibility, allowing it to adapt to possible changes in the relative positions of different components during installation and operation, ensuring dust transport. The continuity and sealing of the channel allow the large end (dust inlet) of the dust inlet hood 35 to face more positions, preventing dust leakage. During the transmission process, the mixed airflow maintains a certain flow rate and pressure to ensure that the dust can be smoothly transported to the next processing stage. After the mixed airflow enters the sorting cylinder 37 through the first connecting pipe 38, when the solenoid valve 311 is in the open state, under the action of gravity and airflow, larger particles of impurities, due to their greater weight, will overcome the lifting force of the airflow, move downwards, and fall into the collection box 312 threaded at the bottom of the sorting cylinder 37. The smaller dust particles, due to their light weight, continue to move upwards under the carrying force of the airflow and enter the bag filter 39 through the second connecting pipe 310. The filter bags inside the bag filter 39 can effectively intercept the dust, which is collected in the collection box at the bottom of the bag filter 39, thus achieving dust collection. The filtered gas is discharged from the device through the third connecting pipe 314 under the action of the auxiliary fan 313, completing the entire dust removal process.

[0022] In one embodiment of this utility model, an auxiliary component 4 is provided on the outside of the second support 2. The auxiliary component 4 includes a circular strip 41. The circular strip 41 is fixedly installed on the outside of the rectangular filter plate 36. The circular strip 41 has a through groove 42. In addition, there are four sets of circular strips 41, and the centers of the circular cross sections of the four sets of circular strips 41 are coaxial. There are six sets of through grooves 42 on a single set of circular strips 41, which can prevent sheet materials from being sucked up and directly attached to the outside of the rectangular filter plate 36, so that the dust cannot be sucked away. In addition, the top end of the bent pipe 43 is fixedly installed on one end of the first connecting pipe 38 inside the sorting cylinder 37. The bottom end of the conical cover 44 is fixedly installed on the small end. In addition, a circular filter plate 45 is fixedly installed inside the top end of the sorting cylinder 37. The circular filter plate 45 is located directly above the bent pipe 43. The inner diameter of the filter holes on the circular filter plate 45 is smaller than the inner diameter of the filter holes on the rectangular filter plate 36, so as to better remove large particulate impurities in the dust.

[0023] In this embodiment, when the dust removal assembly 3 is working, the circular strip 41 fixedly installed on the outside of the rectangular filter plate 36 plays a role. When sheet-like material is adsorbed and approaches the rectangular filter plate 36, the circular strip 41 can directly adhere to the sheet-like material, preventing it from directly adhering to the outside of the rectangular filter plate 36. This ensures that dust can normally enter the dust inlet hood 35 through the through groove 42, avoiding the blockage of the rectangular filter plate 36 by sheet-like material and thus ensuring the normal operation of the dust removal assembly 3. Inside the sorting cylinder 37, the first connecting pipe 38 is located inside the sorting cylinder 37 with a bent pipe 43 fixedly installed at one end. The bottom opening of the bent pipe 43 faces the collection box 312, and the bottom end of the bent pipe 43 is fixed. The fixed conical hood 44 has a conical structure that is smaller at the top and larger at the bottom. When the mixed airflow enters the sorting cylinder 37, impurities are more likely to move downward along the inclined surface of the conical hood 44 under the combined action of gravity and airflow, and eventually fall into the collection box 312. Meanwhile, the dust particles with smaller particle sizes are more affected by the airflow and move upward under the push of the airflow. The inner diameter of the filter holes of the circular filter plate 45 is smaller than the inner diameter of the filter holes opened on the rectangular filter plate 36, which can further intercept large particles of impurities in the upward-moving dust, allowing the smaller particles of dust to pass smoothly and enter the second connecting pipe 310, thereby realizing the separation of impurities and dust, improving the practicality of the device and the dust treatment effect.

[0024] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the suction fan 31, the bag filter 39, the solenoid valve 311, and the auxiliary fan 313. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
