Description

Technical Field

[0001] The invention belongs to the technical field of fabric shaping, and in particular relates to a steam shaping machine with a decontamination function. Background Art

[0002] In the production process of traditional socks, the socks are generally washed and dried before being shaped, and then dried after high temperature and high pressure shaping. With my country's increasingly stringent environmental protection requirements and increasingly fierce industry competition, general sock factories adopt the color-dyed socks process, and the socks are not washed and dried after weaving, and the normal pressure high temperature steam shaping machine that does not require high pressure boiler equipment is widely used; in the shaping process of the normal pressure high temperature steam shaping machine, in order to ensure the steam required in the shaping process, the method currently used in the market is to continuously spray water mist in front of the heating chamber to vaporize into steam or use a small steam generator to spray steam; under the action of the circulating air supply device, these steam air flows enter the shaping chamber to heat the socks and are continuously discharged from the exhaust port of the shaping chamber. After being heated in the heating chamber, they flow back from the air inlet of the shaping chamber to heat the socks in the shaping chamber again, and the cycle repeats until the steam temperature reaches the shaping process requirements; this shaping method does not require a high-power high temperature and high pressure boiler, has a significant energy-saving effect, simple equipment, low investment, easy operation, and has achieved significant economic benefits.

[0003] The above-mentioned steam supply method needs to control the amount of water sprayed and the water spray needs to be well atomized when spraying water. When a small steam generator is used to supply steam, a steam-water separator needs to be installed to prevent unvaporized water mist from being brought into the setting room and causing adverse effects on the setting. In addition, in the process of yarn production and sock knitting, a large amount of knitting oil needs to be added to ensure the smooth spinning and knitting of socks. Fine dust and flying flowers will also be generated during the manufacturing process and attached to the sock blanks. For socks that have not been washed, the oil agent will continue to evaporate during the normal pressure and high temperature setting process, and dust and flying flowers will fly inside the machine. Some dyes and chemicals will also evaporate, and the volatile oil agent will form a kind of oil smoke inside the machine. Under the action of the circulating fan device, the medium airflow in the setting room is continuously discharged from the exhaust port of the setting room and refluxed from the air inlet, and the cycle repeats. With the increase of setting temperature and setting time, the concentration of oil fume in the setting room will become larger and larger. Part of the oil fume will re-liquefy and mix with dust, flying flowers and aluminum powder ground off by the sock board on the sock rod during the collision with the sock setting plate and the inside of the machine, forming a dark oil stain. In addition, during the steam supply process, if improper operation allows unvaporized water mist to enter the setting room, the combination of these water mists and oil fume will produce more serious oil pollution; this oil stain not only pollutes the inside of the machine, the setting plate and the sock rod, but also pollutes the finished product after setting, and pollutes the hands of the plate workers, often causing light-colored finished products to be unqualified, and also brings considerable trouble to the workers' operation. In addition, during the loading and unloading process before and after the socks are set, some oil fume also evaporates into the workshop air, polluting the production environment and bringing adverse effects to the health of workers. my country is the world's largest sock producer, with an annual export volume of more than 16 billion pairs. Designing and producing an economical and practical atmospheric pressure steam setting machine with decontamination function has very important practical significance and broad market prospects. Summary of the invention

[0004] The purpose of the present invention is to provide a steam setting machine with a decontamination function to solve the technical problems of product contamination, difficulty in worker operation and production environment pollution caused by oil pollution generated during the high-temperature setting process.

[0005] In order to solve the above technical problems, the specific technical solutions adopted by the present invention are as follows:

[0006] A steam setting machine with a decontamination function, comprising a setting chamber with an air inlet and an exhaust port, and a circulating fan device, wherein the air outlet of the setting chamber is connected to the chamber air inlet end of the chamber, and the chamber air outlet end of the chamber is connected to the air inlet of the setting chamber; a steam / water nozzle and a baffle assembly are arranged in the chamber, and the lower part of the baffle assembly is connected to the sewage outlet;

[0007] The baffle assembly is provided with a plurality of side-by-side vertical plates, each of which has an acute angle or an obtuse angle with the airflow direction in the chamber, and each of which has a bent flange at one end close to the air outlet end of the chamber.

[0008] Thus, under the action of the circulating fan, the medium airflow circulates in the setting machine, and the oil smoke and dust entering the chamber combine with the steam or water mist sprayed by the steam / water nozzle in the chamber to form oil droplets with a larger specific gravity. These oil droplets mixed in the medium airflow and the unvaporized water mist impact the baffle of the baffle assembly attached to the chamber with the medium airflow to form a liquid film. Under the action of wind force, the liquid film gathers at the bent flange, slides down under the action of gravity and is discharged through the sewage outlet. This solution effectively purifies the oil mixed in the medium airflow, and also removes the moisture in the medium gas, avoiding the pollution of the setting equipment and products by the oil, facilitating the operation of the workers, and improving the yield rate of the sock setting process.

[0009] Furthermore, the circulating fan device includes a centrifugal fan and an arc-shaped air duct, the air inlet of the centrifugal fan is connected to the chamber air outlet of the chamber, the air outlet of the centrifugal fan is connected to one end of the arc-shaped air duct, and the other end of the arc-shaped air duct is connected to the air inlet of the shaping chamber; the lower part of the arc-shaped air duct is provided with an air distribution opening, and the air distribution opening is connected to the sewage outlet. The medium airflow that has undergone the first stage of purification in the chamber will still contain gaseous pollutants, and will pass through the second stage of pollution removal of the circulating fan device again. The centrifugal motion will cause the gaseous pollutants with a larger specific gravity to be squeezed to the outer cover side of the centrifugal fan and the arc-shaped air duct connected thereto and discharged through the air distribution opening. The two-stage pollution removal structure fully purifies the medium airflow, further ensuring the pollution removal effect.

[0010] Furthermore, the circulating fan device includes a centrifugal fan and an arc-shaped air duct, the air inlet of the centrifugal fan is connected to the exhaust port of the shaping chamber, the air outlet of the centrifugal fan is connected to one end of the arc-shaped air duct, and the other end of the arc-shaped air duct is connected to the chamber air inlet end of the chamber; the lower part of the arc-shaped air duct is provided with an air distribution opening, and the air distribution opening is connected to the sewage outlet. The centrifugal fan is directly connected to the shaping chamber, which meets the structural requirements of the relevant machine model. The medium airflow first passes through the circulating fan device, and the centrifugal motion causes the gaseous dirt with a larger specific gravity to be squeezed to the centrifugal fan and the outer cover side of the arc-shaped air duct connected thereto and discharged through the air distribution opening. The medium airflow first passes through the circulating fan device for the first decontamination, and still contains dust and some gaseous dirt, and flows through the chamber again for secondary decontamination. The two-stage decontamination structure fully purifies the medium airflow, further ensuring the decontamination effect.

[0011] Furthermore, the shaping machine also includes a branch air duct, one end of which is connected to the branch air opening, and the other end of which is connected to the sewage outlet; an air volume regulating device is provided in the branch air duct, which can adjust the air volume blown out from the branch air opening, adjust the sewage discharge efficiency, and ensure the requirements of the sock shaping on the steam flow fluidity.

[0012] Furthermore, each of the vertical plates is connected via a positioning top plate and a positioning bottom plate that are arranged opposite to each other, and each of the vertical plates is rigidly connected to form a movable baffle assembly.

[0013] Furthermore, the baffle assembly is inserted into the chamber, and the baffle assembly is easy to disassemble and clean, thereby improving work efficiency.

[0014] The present invention has the following advantages:

[0015] 1. The chamber of the present invention is provided with a baffle assembly and a steam / water nozzle, which are mainly used to separate the liquid dirt in the medium gas and the liquid dirt attached to the medium gas after the impact with the vertical plate, and also prevent the existing setting machine from having unvaporized water mist and water droplets entering the setting chamber to cause adverse effects on the set products (such as dye migration, oil pollution, etc.). At the same time, these unvaporized water mists are used to clean the medium gas, which reduces the difficulty of using the nozzle when the setting machine uses water spray to produce steam, or avoids the requirement of installing a steam-water separator when using a small steam generator to provide steam, thereby saving resources and saving investment.

[0016] 2. The two-stage decontamination structure of the present invention complements each other and has its own emphasis: the chamber device is used to mainly separate liquid dirt in the medium gas and liquid dirt and moisture attached to the medium gas and the vertical plate after impact, and the circulating fan device composed of a centrifugal fan and an arc-shaped air duct is used to mainly separate gaseous dirt with a specific gravity greater than that of steam in the medium gas. The medium gas circulates back and forth in the two-stage decontamination structure, the heating chamber and the shaping chamber until the temperature in the shaping chamber meets the shaping process requirements and the shaping process is terminated, so that the medium gas is fully purified, achieving an ideal decontamination effect, improving the yield rate of sock shaping processing, reducing the difficulty of workers' operation, and improving the production environment of sock shaping.

[0017] 3. The baffle assembly of the present invention is easy to clean. In addition, the baffle assembly includes a plurality of side-by-side vertical plates and a bent flange is provided at the end of each vertical plate, which effectively improves the blocking efficiency of the baffle assembly and enhances the decontamination effect.

[0018] 4. The present invention is provided with a branch air duct and an air volume regulating device in the branch air duct, so as to control the exhaust volume of the branch air outlet while discharging sewage, adjust the sewage discharge efficiency, and ensure the requirements of the sock shaping on the fluidity of the medium air flow.

[0025] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a steam setting machine with a decontamination function of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1 As shown, the steam setting machine with a decontamination function of this embodiment mainly includes a setting chamber 1, a circulating fan device, a steam / water nozzle 4 and a baffle assembly 5 arranged in a chamber 3, a heating chamber 13, a temperature probe 14, etc. The setting chamber 1 includes an air inlet 101 and an exhaust port 102. The exhaust port 102 of the setting chamber 1 is connected to the chamber air inlet end 31 of the chamber 3. The exhaust port 102 of the setting chamber 1 is provided with a filter 8, and the filter 8 can perform a coarse filter on the air flow flowing out of the setting chamber 1. After the medium airflow flows through the chamber 3, the liquid dirt and water in the medium gas are removed. Then the medium airflow passes through the circulating fan device, and the circulating fan device separates the gaseous dirt in the medium gas whose specific gravity is greater than the specific gravity of steam. As a result, the medium gas is fully purified, the yield rate of the socks setting process is improved, the operation difficulty of the workers is reduced, and the production environment of the socks setting is improved.

[0027] like Figure 1As shown, the setting machine is started, and the circulating fan device and the heating chamber 13 start working. Under the action of the circulating fan device, the medium airflow (air at this time) in the setting chamber 1 is repeatedly heated in the heating chamber 13. At this time, the temperature of the medium airflow and the socks in the setting chamber 1 continues to rise. When the temperature rises to a certain level, oil smoke will begin to evaporate from the socks and mix into the medium airflow. When the temperature probe 14 senses that the temperature of the medium airflow reaches the set process value, the steam / water nozzle 4 is started to work. Since the normal setting temperature of textile fibers is much higher than the vaporization temperature of water, when only water mist is sprayed, the temperature and heat of the medium airflow can also vaporize the water mist to form a steam medium sufficient for setting.

[0028] like Figure 1 , Figure 3 , Figure 5 As shown, the medium airflow enters the chamber 3 after initially filtering out flying impurities through the filter screen 8 from the exhaust port 102 of the shaping chamber 1. The steam or water mist sprayed by the steam / water nozzle 4 at the air inlet end 31 of the chamber continuously impacts the medium airflow entering the chamber 3, and causes the oil smoke and dust in the medium airflow to mix with the steam to form oil droplets with greater specific gravity and viscosity. These oil droplets continue to move forward at a certain speed in the chamber 3 with the medium airflow. When impacting the vertical plate 51 of the baffle assembly 5 at a certain angle to the airflow direction, these oil droplets and the water mist that has not yet volatilized and the liquid dirt formed by the impact of the medium gas and the vertical plate form a layer of liquid film on the plane of the vertical plate 51. When these liquid films move to the end of the vertical plate 51, they are blocked by the bent flange 511, slide down under the action of gravity and are discharged outside the machine through the sewage outlet 6. Other gaseous medium airflows pass over the bent flange 511 and enter the chamber outlet 32 ​​through the gap between the baffle assemblies 5. The vertical plates 51 of the baffle assembly 5 are connected together through the corresponding positioning top plate 11 and the positioning bottom plate 12, and can be inserted into the chamber 3. The lower end of the baffle assembly 5 extends to below the bottom plate 15 of the chamber air outlet end and is connected to the sewage outlet 6.

[0029] like Figure 1 , Figure 2 , Figure 4As shown, the circulating fan device includes a centrifugal fan 21 and an arc-shaped air duct 22, the air inlet 211 of the centrifugal fan 21 is connected to the chamber outlet 32 ​​of the chamber 3, and the air outlet 212 of the centrifugal fan 21 is connected to one end of the arc-shaped air duct 22. The medium gas that reaches the chamber outlet 32 ​​after being decontaminated in the chamber 3 still has some oil gas and gasified dyes that are not liquefied and cannot be blocked by the baffle assembly 5, and a small amount of dust and other pollutants that are not successfully blocked by the baffle assembly 5. These medium air flows flow to the circulating fan device, and the medium gas performs centrifugal motion under the action of the impeller of the high-speed rotating centrifugal fan 21 and is accelerated to be thrown to the inner side of the outer cover plate 16 of the fan volute and the outer cover plate 16 of the arc-shaped air duct 22, and moves in the flow direction of the medium gas at the same time. The lower part of the outer cover plate 16 of the arc-shaped air duct 22 is provided with an air distribution opening 7, and the air distribution opening 7 is connected to the sewage outlet 6 through the air distribution duct 9, and an air volume regulating device 10 is arranged in the air distribution duct 9. Preferably, the arc-shaped air duct 22 is located at a low position, and the center of the centrifugal fan 21 is located at a high position. Since the specific gravity of the gaseous oil smoke and other dust pollutants in the medium airflow is greater than the specific gravity of the steam, these pollutants will be preferentially squeezed and attached to the inner side of the outer cover plate 16 of the arc-shaped air duct 22. When sliding to the air distribution opening 7 set on the outer cover plate 16 of the arc-shaped air duct 22, under the action of inertial force, the oil gas and gasified dyes and other pollutants with high specific gravity preferentially enter the air distribution duct 9 through the air distribution opening 7 and are discharged through the sewage outlet 6; most of the medium airflow reaches the heating chamber 13 after secondary decontamination by the circulating fan device, and is reheated and then flows back to the shaping chamber 1. Since the amount of steam provided to the setting machine through the steam / water nozzle 4 is fixed, an air volume regulating device 10 is installed in the air distribution duct 9 to adjust the amount of air discharged from the air distribution opening 7, adjust the sewage discharge efficiency, and ensure the requirements for air flow when the socks are set.

[0030] This cycle repeats itself, so that the temperature and cleanliness of the medium airflow become higher and higher; when the temperature probe 14 senses that the temperature of the medium airflow has reached the set shaping temperature, the control device starts other programs to complete the shaping process. The two-stage purification structure improves the decontamination efficiency, fully purifies the oil and impurities in the shaping medium airflow, improves the production environment of sock shaping, improves the yield of sock shaping processing, reduces the loss burden of producers, and reduces production costs. It should be noted that the arrangement order of the circulating fan device and the chamber 3 provided with the steam / water nozzle 4 and the baffle assembly 5 can be interchanged to form a new technical solution to adapt to different machine structure requirements. The medium airflow first passes through the circulating fan device for the first stage of decontamination, and then passes through the chamber for the second stage of decontamination. In addition, the setting positions of the heating chamber 13 and the temperature probe 14 can also be reconfigured according to actual needs to achieve the same technical effect.
