[0002] The circular knitting machine workshop is the place where the workers carry out textile operations. Many circular knitting machines that make cotton yarn will produce a lot of cotton fibers. Most of these cotton fibers are relatively small and can float around in the workshop with the movement of people or slight air flow. They can easily enter the human respiratory tract and affect the workers' respiratory health. Moreover, these cotton fibers are often flammable. If they are not handled in time, fires are very likely to occur. Therefore, there are great safety hazards and the consequences are very serious.

[0003] The traditional dust removal system in textile workshops is to lay pipes underground, create a vacuum in the pipes, and suck the cotton yarn that falls on the floor into the pipes. There is no air circulation, and the temperature and humidity of the air cannot be adjusted. In addition, traditional dust removal equipment is usually in full power mode, which consumes a lot of energy.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] The invention discloses a dust removal device for a large circular knitting machine workshop, aiming to solve the shortcomings of the existing dust removal equipment.

[0029] See also Figure 1 and Figure 2, an embodiment of the present invention provides a dust removal device for a large circular knitting machine workshop, comprising: a plurality of large circular knitting machine work isolation workshops 1, an air inlet duct 2 arranged at the top of the large circular knitting machine work isolation workshop 1, an air outlet duct 3 arranged at the bottom of the large circular knitting machine work isolation workshop 1, an air suction mechanism 6 arranged at the outlet of the air outlet duct 3, a dust removal mechanism 4 connected to the air suction mechanism 6, a temperature and humidity control chamber 5 connected to the output end of the dust removal mechanism 4, an air supply mechanism 7 for connecting the temperature and humidity control chamber 5 and the air inlet duct 2, and an MES system;

[0030] Among them, the top of each large circular knitting machine working isolation workshop 1 is equipped with an air inlet device 8, and the bottom of each large circular knitting machine working isolation workshop 1 is equipped with an air outlet device 9, the air inlet device 8 is connected to the air inlet duct 2, and the air outlet device 9 is connected to the air outlet duct 3;

[0031] It should be noted that the inventors found that in the prior art, the dust removal equipment in the large circular knitting machine workshop generally lays pipes at the bottom and creates a vacuum in the pipes at the bottom to achieve the suction of the cotton yarn that falls on the ground. There is no circulation of air inlet and outlet, and the equipment needs to be running all the time to achieve the vacuum in the pipe.

[0032] In this embodiment, each of the large circular knitting machine working isolation workshops 1 is equipped with a data acquisition device 12 for acquiring the working status of the large circular knitting machine, wherein the data acquisition device can also be electrically connected to the temperature sensor 10 and the humidity sensor 11 configured in the large circular knitting machine working isolation workshop 1 to collect the temperature and humidity values ​​of the isolation workshop.

[0033] The MES system is used to collect the isolation workshop data of the circular knitting machine isolation workshop 1. When it is determined that there is no circular knitting machine in operation according to the isolation workshop data, the suction mechanism 6 and the air supply mechanism 7 are controlled to operate at the first power, so that the air outlet duct 3 and the air inlet duct 2 form a circulating convection, and the dust in the isolation workshop enters the dust removal mechanism 4 through the air outlet device 9, which can prevent the dust removal equipment from always operating at high power, wasting electric energy and reducing the service life of the equipment;

[0034] When it is determined based on the data of the isolation workshop that a large circular knitting machine is in operation, the air suction mechanism 6 and the air supply mechanism 7 are controlled to operate at the second power so that the air outlet duct 3 and the air inlet duct 2 form a circulating convection, and the cotton wool in the isolation workshop enters the dust removal mechanism 4 through the air outlet device 9. At the same time, based on the temperature and humidity values ​​collected by the temperature sensor 10 and the humidity sensor 11 in the isolation workshop, the temperature and humidity of the temperature and humidity control chamber 5 are adjusted, which can effectively settle the cotton dust and then effectively remove the dust based on the circulating convection.

[0035] In a possible embodiment of the present invention, the dust removal mechanism 4 includes: a primary dust removal box 41, a secondary dust removal box 42, and a tertiary dust removal box 43 connected in sequence;

[0036] The input end of the first-stage dust removal box 41 is connected to the output end of the suction mechanism 6 , and the output end of the third-stage dust removal box 43 is connected to the temperature and humidity control chamber 5 .

[0037] It should be noted that the primary dust removal box 41 is used to filter larger particles such as yarn wool;

[0038] The secondary dust removal box 42 is used to filter relatively fine particles;

[0039] The three-stage dust removal box 43 is used to filter the smallest dust particles.

[0040] In this embodiment, after the air impurities in the air outlet duct 3 are filtered in multiple stages by the dust removal mechanism 4, the clean air enters the temperature and humidity control chamber 5, wherein the temperature and humidity control chamber 5 includes a humidity control chamber and a temperature control chamber, the humidity control chamber is used to control the humidity of the filtered air, and the temperature control chamber is used to control the temperature of the filtered air.

[0041] In a possible embodiment of the present invention, the air suction mechanism 6 is configured to deliver the air in the air outlet duct 3 into the dust removal mechanism 4 during operation.

[0042] It should be noted that the suction mechanism 6 can be a powerful suction motor, which can achieve the function of vacuuming the air outlet duct 3.

[0043] In a possible embodiment of the present invention, the air supply mechanism 7 is configured to deliver constant temperature and humidity air into the air inlet duct 2 during operation.

[0044] It should be noted that the air supply mechanism 7 can be a powerful air supply motor, which can deliver filtered constant temperature and humidity air into the air inlet duct 2.

[0045] In a possible embodiment of the present invention, the air intake device 8 includes: an air intake control valve 81, an auxiliary air intake fan 82, and an umbrella-shaped air outlet 83;

[0046] The auxiliary air inlet fan 82 is disposed between the air inlet control valve 81 and the umbrella-shaped air outlet 83;

[0047] The air inlet control valve 81 is configured to open and close the connection between the umbrella-shaped air outlet 83 of the air inlet duct 2;

[0048] The blades of the umbrella-shaped air outlet 83 can adjust the wind direction so that the yarn wool is blown to the ground;

[0049] It should be noted that the air inlet control valve 81 is used to open and close the air duct connection between the air inlet duct 2 and the isolation workshop. In some special circumstances, such as when a fire occurs, it is necessary to close the air inlet control valve 81 in time to avoid continuous entry of air. Under normal circumstances, the auxiliary air inlet fan 82 is used to assist constant temperature and humidity air to enter the isolation workshop.

[0050] Furthermore, the umbrella-shaped air blowing port 83 can direct the wind to the working part of the circular knitting machine so that yarn hair, dust and the like are blown to the ground by the warm and humid air.

[0051] In a possible embodiment of the present invention, the air outlet device 9 includes: a strip-shaped long hole air outlet 13, an air outlet control valve 92, and an auxiliary blower 91;

[0052] The air outlet control valve 92 is disposed between the auxiliary blower 91 and the strip-shaped long hole air outlet, and is used to open and close the strip-shaped long hole air outlet.

[0053] It should be noted that the air outlet control valve 92 is used to open and close the air duct connection between the air outlet duct 3 and the isolation workshop. In some special circumstances, such as when a fire occurs, it is necessary to close the air outlet control valve 92 in time to avoid air circulation. Under normal circumstances, the auxiliary blower 91 is used to assist in exhausting the air containing yarn hair and dust from the isolation workshop. Furthermore, in this embodiment, the strip-shaped long hole air outlet adopts a design similar to that of a vacuum cleaner, and uses a slender (about 1CM in height) air outlet to increase the suction pressure, thereby effectively inhaling yarn hair.

[0054] Based on the dust removal equipment for a large circular knitting machine workshop provided by the present invention, the isolation workshop data of the large circular knitting machine working isolation workshop 1 is collected through the MES system. When it is judged according to the isolation workshop data that the large circular knitting machine is not in operation, the suction mechanism 6 and the air supply mechanism 7 are controlled to operate at the first power, so that the air outlet duct 3 and the air inlet duct 2 form a circulating convection, and the dust in the isolation workshop enters the dust removal mechanism 4 through the air outlet device 9, which can avoid the dust removal equipment from always running at high power, wasting electric energy and reducing the service life of the equipment. When it is judged according to the isolation workshop data that the large circular knitting machine is in operation, the suction mechanism 6 and the air supply mechanism 7 are controlled to operate at the second power, so that the air outlet duct 3 and the air inlet duct 2 form a circulating convection, and the cotton wool in the isolation workshop enters the dust removal mechanism 4 through the air outlet device 9. At the same time, based on the temperature and humidity of the isolation workshop, the temperature and humidity of the temperature and humidity control room 5 are adjusted, which can effectively settle the cotton dust, and then effectively remove the dust based on the circulating convection.
