Description

Technical Field

[0001] This utility model relates to the technical field of honeycomb ceramic production equipment, and in particular to a soot blowing device for honeycomb ceramic production. Background Technology

[0002] Honeycomb ceramics are high-performance ceramic materials with a regular porous channel structure. Due to their high specific surface area, low coefficient of thermal expansion, excellent thermal shock resistance, and chemical corrosion resistance, they are widely used in key areas such as automotive exhaust catalytic converters (catalyst carriers), regenerative thermal oxidizers (RTOs), molten metal filters, and infrared radiation plates. In these applications, the cleanliness of the honeycomb ceramic carrier surface directly determines the uniformity and amount of subsequent catalyst coating, thus profoundly affecting the catalytic efficiency, service life, and system energy consumption of the final product. Therefore, in its production process, after sintering, cutting, and edge grinding, thorough and efficient surface cleaning of the products is an indispensable key step to ensure product performance and yield.

[0003] Currently, cleaning methods in the industry have significant limitations: Manual cleaning relies mainly on manual use of air guns or brushes for blowing. This method is inefficient, produces inconsistent cleaning quality, and generates a large amount of fugitive dust, endangering the health of workers and becoming a bottleneck restricting the automation and environmental upgrade of production lines. To improve manual cleaning, existing solutions often install air blowing and suction devices facing each other above the conveyor line. Although this method aims to achieve immediate collection, its design has inherent flaws: First, cleaning only acts on the upper surface of the product, leaving the lower surface and the conveyor belt itself without handling dust, resulting in incomplete cleaning; second, the opposing airflows are prone to collision and turbulence, causing dust to escape, thus hindering cleaning and collection efficiency; finally, it is difficult to effectively remove micro-dust inside the pores of honeycomb ceramics.

[0004] Therefore, developing an automated cleaning device that can achieve comprehensive, high-efficiency, and effective dust collection is an urgent need to solve current production pain points. Utility Model Content

[0005] Purpose of the invention: The purpose of this utility model is to provide a dust blowing device for honeycomb ceramic production. Through the staggered blowing and suction layout of the upper and lower cleaning devices, it solves the problems of many cleaning dead corners, serious dust dispersion, and low airflow collision efficiency of traditional methods. It realizes simultaneous cleaning of the upper and lower surfaces of the product and real-time dust collection, which significantly improves cleaning quality, environmental protection and energy efficiency.

[0006] Technical solution:

[0007] A soot blowing device for producing honeycomb ceramics includes a conveying mechanism. An upper cleaning device is disposed above the conveying mechanism, and a lower cleaning device is disposed below the conveying mechanism. The upper cleaning device includes a soot blowing mechanism and a soot suction mechanism arranged alternately along the conveying direction. The lower cleaning device also includes a soot blowing mechanism and a soot suction mechanism arranged alternately along the conveying direction. On the same axis along the conveying direction, the soot blowing mechanism of the upper cleaning device and the soot suction mechanism of the lower cleaning device are arranged vertically corresponding to each other. The soot suction mechanism of the upper cleaning device and the soot blowing mechanism of the lower cleaning device are arranged vertically corresponding to each other.

[0008] Furthermore, the conveying mechanism is a mesh belt conveyor, and the bearing surface of the mesh belt conveyor has gaps or mesh holes for airflow.

[0009] Furthermore, the soot blowing mechanism includes an air supply fan and a plurality of air blowing nozzles arranged in a matrix, the outlet direction of the air blowing nozzles being towards the bearing surface of the conveying mechanism.

[0010] Furthermore, the dust collection mechanism includes a dust collection pipe and a plurality of dust collection pipes arranged in a matrix connected to the dust collection pipe, with the air intake of the dust collection pipe facing the bearing surface of the conveying mechanism.

[0011] Furthermore, a horn-shaped dust collection hood is provided on the outer periphery of the suction pipe.

[0012] Furthermore, the dust collection pipes of all dust collection mechanisms are connected to a common dust collection manifold, which is connected to an air suction fan.

[0013] Furthermore, the dust collection pipe is a corrugated flexible hose.

[0014] Furthermore, the upper cleaning device is connected to the equipment frame via a lifting drive mechanism, which includes a drive motor, a lead screw driven by the drive motor, and a lifting seat that cooperates with the lead screw and is fixedly connected to the upper cleaning device.

[0015] Furthermore, the lifting drive mechanism also includes a guide rod and a guide block disposed on the lifting seat, wherein the guide rod and the guide block are slidably connected.

[0016] Beneficial effects:

[0017] 1. By combining staggered blowing and suction mechanisms, simultaneous cleaning of the upper and lower surfaces of honeycomb ceramic products is achieved. The upper mechanism cleans the upper surface, while the lower mechanism cleans the lower surface and conveyor belt gaps, eliminating cleaning dead angles. The staggered arrangement along the conveying direction causes the products to undergo multiple cycles of being blown up and sucked away during transport, making the cleaning process dynamic and continuous, significantly improving cleaning efficiency and cleanliness.

[0018] 2. The upper dust-blowing mechanism faces the lower dust-suction mechanism, and vice versa. This three-dimensional staggered layout fundamentally eliminates the possibility of direct collision between the upper and lower high-pressure airflows. The airflow path is designed as follows: the airflow blown from above strips away dust and drives it downwards, where it is efficiently captured by the suction port directly below; the airflow blown from below lifts the dust at the bottom upwards, where it is promptly sucked away by the suction port directly above. This design allows the blowing and suction airflows to complement each other, forming an orderly directional flow field with high energy utilization. It also effectively confines dust within the clean space formed by the blowing and suction mechanisms, greatly reducing the escape of dust into the workshop environment.

[0019] 3. All dust collection mechanisms are connected to a central suction fan via a main dust collection pipe, forming a powerful negative pressure collection system. This dust collection system works precisely in tandem with the dust blowing action, drawing dust into the pipes the instant it is blown up, achieving immediate dust collection upon production. This not only significantly improves the working environment and meets environmental protection requirements but also reduces unnecessary material loss, making it particularly suitable for handling honeycomb ceramic debris containing precious metal catalysts.

[0020] 4. The height of the upper cleaning device can be adjusted through a precision lifting drive mechanism, allowing the equipment to flexibly adapt to honeycomb ceramic products of different thicknesses and specifications.

[0021] 5. The use of a mesh belt and other breathable conveying mechanism provides a foundation for double-sided cleaning. The suction pipe uses a corrugated flexible hose, which is easy to install and fine-tune, and can buffer vibration. The horn-shaped dust collection hood can expand the negative pressure area and improve dust collection efficiency. The entire equipment has a reasonable structural design, stable operation, and is easy to maintain. Attached Figure Description

[0027] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-5 As shown, a soot blowing device for honeycomb ceramic production includes a conveying mechanism 1. An upper cleaning device 2 is positioned above the conveying mechanism 1, and a lower cleaning device 3 is positioned below it. The upper cleaning device 2 includes a soot blowing mechanism 4 and a soot suction mechanism 5 arranged alternately along the conveying direction. The lower cleaning device 3 also includes a soot blowing mechanism 4 and a soot suction mechanism 5 arranged alternately along the conveying direction. On the same axis along the conveying direction, the soot blowing mechanism 4 of the upper cleaning device 2 and the soot suction mechanism 5 of the lower cleaning device 3 are arranged vertically correspondingly. The soot suction mechanism 5 of the upper cleaning device 2 and the soot blowing mechanism 4 of the lower cleaning device 3 are also arranged vertically correspondingly. This staggered, corresponding core layout forms the basis of the device's working principle, ensuring that the high-speed cleaning airflow ejected from the soot blowing mechanism 4 does not directly collide with the airflow from the opposite soot blowing mechanism 4, thereby avoiding energy loss and airflow turbulence. Instead, the airflow from the upper dust blowing mechanism 4 blows the dust towards the corresponding dust suction mechanism 5 below, and the airflow from the lower dust blowing mechanism 4 blows the dust towards the corresponding dust suction mechanism 5 above. The blowing and collecting actions form a highly efficient and coordinated directional flow field in three-dimensional space.

[0030] In this embodiment, the upper cleaning device 2 includes a central dust-blowing mechanism 4 and two side dust-absorbing mechanisms 5; the lower cleaning device 3 includes a central dust-absorbing mechanism 5 and two side dust-blowing mechanisms 4. It can be understood that the number of dust-blowing mechanisms 4 and dust-absorbing mechanisms 5 in the upper cleaning device 2 can also be other numbers, as long as they are staggered, and the lower cleaning device 2 is correspondingly arranged.

[0031] The conveying mechanism 1 is a mesh belt conveyor, and the bearing surface of the mesh belt conveyor has gaps or mesh holes for airflow. This structure is key to achieving double-sided cleaning of the equipment. It allows the airflow of the upper cleaning device 2 to pass through the mesh holes and act on the lower surface of the product, while also allowing the airflow of the lower cleaning device 3 to penetrate upwards, cleaning the bottom of the product and the conveyor belt itself, ensuring unobstructed airflow channels.

[0032] The dust blowing mechanism 4 includes an air supply fan 41 and multiple matrix-arranged air nozzles 42, with the outlet direction of the air nozzles 42 facing the bearing surface of the conveyor mechanism 1. The air supply fan 41 provides a stable air source, and the multiple matrix-arranged air nozzles 42 can form a blowing surface that uniformly covers the width of the conveyor belt, ensuring that every point on the surface of the honeycomb ceramic product passing through is effectively impacted by the airflow, thus completely removing the attached dust.

[0033] The dust collection mechanism 5 includes a dust collection pipe 51 and multiple suction pipes 52 arranged in a matrix and connected to the dust collection pipe. The suction ports of the suction pipes 52 face the bearing surface of the conveying mechanism 1. The multiple suction pipes 52 are also arranged in a matrix to form a negative pressure collection surface that matches the blowing surface. Each suction pipe 52 is responsible for capturing the dust in its corresponding area, which is collected by the dust collection pipe 51 and then discharged, achieving efficient and targeted dust collection.

[0034] The outer periphery of the suction pipe 52 is provided with a trumpet-shaped dust collection hood 53. The trumpet-shaped dust collection hood 53 can significantly expand the effective negative pressure area at the inlet of the suction pipe 52, capture the blown dust in a gentler and more comprehensive manner, reduce the possibility of dust escaping due to insufficient suction range, and improve the overall dust collection efficiency.

[0035] All dust collection pipes 51 of the dust collection mechanisms 5 are connected to a common dust collection manifold (not shown), which is connected to an air suction fan (not shown). This centralized design integrates all dust collection mechanisms 5 into a unified negative pressure system, powered by a high-power air suction fan. This simplifies the piping layout, ensures sufficient and stable negative pressure throughout the dust collection network, and ensures that dust can be powerfully extracted and transported to the subsequent centralized filtration device.

[0036] The dust collection pipe 51 is a corrugated flexible hose. Utilizing its excellent flexibility and extensibility, it facilitates on-site pipe laying and connection according to the actual space, while also effectively buffering minor vibrations generated during equipment operation or adjustment, improving the reliability and lifespan of the system connection.

[0037] The upper cleaning device 2 is connected to the equipment frame via a lifting drive mechanism 6. The lifting drive mechanism 6 includes a drive motor 61, a lead screw 62 driven by the drive motor 61, and a lifting seat 63 that engages with the lead screw and is fixedly connected to the upper cleaning device 2. The lifting drive mechanism 6 enables the upper cleaning device 2 to have height adjustment capabilities. When the drive motor 61 operates, it drives the lead screw 62 to rotate, thereby driving the lifting seat 63, which meshes with it, to move vertically, ultimately raising and lowering the entire upper cleaning device 2 to accommodate honeycomb ceramic products of different thicknesses, ensuring that the air nozzle 42 and the suction pipe 52 are always at the optimal cleaning distance.

[0038] The lifting drive mechanism 6 also includes a guide rod 64 and a guide block 65 disposed on the lifting seat 63. The guide rod 64 and the guide block 65 are slidably connected. The sliding pair between the guide rod 64 and the guide block 65 provides precise guidance for the vertical movement of the lifting seat 63, preventing it from deflecting or swaying during the lifting process, ensuring the stability and positioning accuracy of the upper cleaning device 2, and maintaining a consistent cleaning effect.

[0039] During operation, honeycomb ceramic products are carried by a mesh belt conveyor 1 at a uniform speed. When the products reach the area below the upper cleaning device 2, the central dust-blowing mechanism 4 is activated, and the matrix-arranged air nozzles 42 spray high-speed airflow downwards to thoroughly clean the upper surface of the products and blow the dust downwards. This blown dust is then efficiently captured by the central dust-collecting mechanism 5 of the lower cleaning device 3, which is located directly below, through its suction pipe 52 and dust collection hood 53. Simultaneously, the dust-blowing mechanisms 4 on both sides of the lower cleaning device 3 blow air upwards to clean the lower surface of the products and the gaps in the mesh belt, and the raised dust is captured by the dust-collecting mechanisms 5 on both sides of the upper cleaning device 2. All the sucked-in dust is collected through the dust collection pipe 51 and the dust collection manifold, and finally drawn into the dust removal system by the suction fan. The height of the upper cleaning device 2 can be adjusted by the lifting drive mechanism 6 to optimize the cleaning spacing under different products. The entire process achieves a spatially coordinated alternation of blowing and collection, with orderly airflow organization, thorough cleaning, and no dust dispersion.

[0040] The embodiments described above are merely illustrative of certain implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
