Description

Technical Field

[0001] The invention relates to the technical field of dust removal systems for ironing machines, and in particular to a self-cleaning circulating air suction dust removal system for ironing machines. Background Art

[0002] In recent years, the textile process from raw materials to finishing has undergone major changes, especially the requirements for clean and energy-saving production are getting higher and higher. The current situation of high energy consumption and low competitiveness in the textile fabric industry has restricted its healthy development. Refined production process and step-by-step energy consumption control are imperative.

[0003] For the finishing industry, especially the ironing process, a large amount of heat energy must be relied upon to maintain the process temperature. During the production process, a large amount of polluted waste gas, waste fluff, and dust particles are generated due to high temperature and mechanical action, causing pollution in the processing process and production safety accidents. Standardized management and control are required. Usually, centralized suction methods are adopted. However, the various forms of waste generated in the process have different physical properties, and the space of the control area is large, requiring a large amount of natural wind to take away, but at the same time, a large amount of high-temperature gas in the processing area is replaced, resulting in energy waste.

[0004] For ironing machines, the operating energy consumption is about 60,000 kcal / hour, and more than 2 / 3 of the working heat energy is discharged externally. There are more than 50,000 units in the domestic market. If the process energy consumption can be gradually reduced, the social and economic benefits will be obvious.

[0005] There are two main types of suction and dust removal technologies for existing ironing machines. One type has a structure with separate upper and lower dust suction devices. Each device has the function of sucking out oil smoke and floating dust. However, for the upper dust suction device, the ironing roller with a spiral groove structure on the surface of the key component rotates at high speed during operation. Combined with the structure of the ironing machine, it has a strong horizontal forward thrust on the oil smoke and waste lint generated, which is perpendicular to the dust suction wind direction. The required dust suction wind pressure and air volume are huge, resulting in a large waste of heat sources. The lower suction also has the same working conditions. The second type is a combined interval structure, that is, the dust suction device boundary is set outside the influence of the ironing roller. The waste lint and floating dust generated have already self-settled before reaching the boundary of the dust suction device. The oil smoke decelerates and floats up and separates, accumulating near the upper suction port, and can be easily sucked out. The self-settled waste lint and particulate matter fall and adhere to the inner cavity of the lower dust collection device. Due to the large surface area of ​​the suction device and the temperature difference with the environment, while dissipating a large amount of heat to the outside, the heavier oil smoke particles in the inner wall area are condensed and liquefied, adhere to the inner wall of the suction device, and mix with the waste lint and particulate matter, which increases the suction force and requires frequent shutdown for cleaning, which has a high risk of production accidents and environmental pollution, and reduces production efficiency. Therefore, we proposed a self-cleaning cycle suction and dust removal system for ironing machines to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example

[0031] like Figure 1-4As shown, a self-cleaning circulating air suction and dust removal system for a calendering machine proposed in one embodiment of the present invention comprises a calendering roller 1, a calendering assembly 2 is arranged on one side of the calendering roller 1, a lower dust suction device 3 and an upper dust suction device 4 are arranged below and above the calendering roller 1, respectively, an external circulation dust filter device 5 is arranged on one side of the calendering roller 1, the external circulation dust filter device 5 is connected with the lower dust suction device 3 and the upper dust suction device 4, the lower dust suction device 3 comprises a lower suction hood 301 with a long dust discharge port and a conical dust discharge channel at the lower end, the lower suction hood 301 is installed on the calendering machine through a connecting assembly 304, an air inlet hole is arranged on the thin end surface of the conical dust discharge channel of the lower suction hood 301, and a fresh air damper 302 is used to adjust the air intake volume, and the inner cavity of the conical dust discharge channel can also be cleaned through the air inlet hole The bottom of the cross-section of the lower air suction hood 301 is a large flat bottom, and a long straight opening is arranged at the back to communicate with the conical dust exhaust duct. A dust reduction buffer zone is arranged on the left side of the opening of the lower air suction hood 301, and it smoothly transitions to the vertical boundary of the cavity, which is convenient for dust accumulation and oil smoke generated by the ironing work to decelerate and float up. The upper half of the boundary of the lower air suction hood 301 is hinged to the upper dust suction device 4 by a hinge, and an operating handle is provided to facilitate daily maintenance operations. The upper part of the lower air suction hood 301 adopts a limiter 306 to position the upper air suction hood rigidly connected to the upper dust suction device 4 at multiple points. Since the dust reduction buffer zone is set for the accumulation of waste lint and the cross-sectional size is large, dust removal by suction through the conical air duct cannot be achieved, and an electric cleaning device is arranged in the dust reduction buffer zone. The movement direction of the electric cleaning device is the same as that of the air ejected by the ironing roller 1 The airflow directions are opposite, and the waste lint balls formed during the cleaning process are more likely to fall into the conical dust exhaust channel and be sucked away. Side panels are provided on both sides of the lower suction hood 301 and are connected to the middle cavity. The side panels are fixed to the middle of the connecting component 304. The surfaces of the lower dust suction device 3, the upper dust suction device 4 and the external circulation dust filter device 5 are coated with heat insulation coatings. The ironing process is to comprehensively utilize the physical properties of the fiber under heating, and use the mechanical pressing method for effective finishing. Due to process requirements, textile lubricants-industrial light white oil must be used in the weaving process of textiles. The final woven textiles usually contain 1.5-2.5% of oil. In the ironing and finishing process, fiber shedding and lubricant volatilization due to heat are inevitable, generating pollutants. In the production process of the ironing machine, By arranging the lower dust suction device 3 and the upper dust suction device 4, the function of upper air suction and lower dust suction is realized, and the sedimentation dust removal mechanism is fully utilized to centrally absorb the fallen hair. After being filtered by the external circulation dust filter device 5, the filtered gas with a relatively high temperature is sent back again to enrich the ironing working chamber, replacing the relatively cold ambient air required for the upper dust suction device 4 to suck, thereby saving heating energy. The dust accumulated in the external circulation dust filter device 5 is mechanically aggregated with low energy consumption. The surfaces of the lower dust suction device 3, the upper dust suction device 4 and the external circulation dust filter device 5 are coated with heat-insulating and heat-preserving coatings, which effectively reduces the liquefaction and viscosity of the generated oil smoke, thereby reducing the adsorption force of the fallen dust, and reducing the difficulty of dust suction. The surface heat-insulating structure effectively reduces the energy loss caused by the heat dissipation of the ironing working area to the normal temperature environment.

When the reduction motor 311 drives the cleaning drive shaft 308 to rotate, the transmission chain 307 is driven by the active sprocket 314 respectively, and the brush plate assembly 309 is driven to translate synchronously through the brush plate connector 315, and moves along the trajectory defined by the chain support 303 to complete the cleaning of the dust reduction buffer area of ​​the lower suction hood 301.
