Description

Technical Field

[0001] This invention belongs to the technical field of polyester-nylon composite yarn production equipment, and particularly relates to a smoke removal and cooling device for polyester-nylon composite yarn production. Background Technology

[0002] The nylon / polyester composite yarn extended products have microfiber monofilaments that are 1 / 20 the size of ordinary fibers. After special processing and finishing, the fabrics are fluffy and soft, with a large specific surface area and abundant capillary effect.

[0003] Chinese Patent (CN202111014176.9) discloses a suction cooling device for the production of polyester-nylon composite yarn. Addressing the problems of poor cooling effect and inability to effectively remove dust from the composite yarn and protect the environment associated with existing suction cooling devices, the following solution is proposed: It includes a refrigeration cabinet with a rotatable cover on its front. Multiple yarn guide tubes are installed inside the refrigeration cabinet, and a cooling box is also installed inside. The multiple yarn guide tubes are all located within the cooling box, which is filled with insulation cotton that wraps around the outside of the yarn guide tubes. Multiple air holes are opened on the outside of the yarn guide tubes, all located on the outside of the cooling box. A refrigeration mechanism is connected to the top of the cooling box, and an air suction cylinder is connected to the outside of the refrigeration cabinet. A propeller is rotatably installed inside the air suction cylinder.

[0004] Chinese Patent (CN201720430078.6) discloses a suction cooling device for the production of polyester-nylon composite yarn, comprising a semi-cylindrical hollow cooling device body. One end of the body is bolted to an inlet guide with an inlet port, and the other end is bolted to an outlet guide with an outlet port. The inlet and outlet ports have V-shaped cross sections, and the bottom of the V-shape of the inlet and outlet ports has a smooth transition surface. The body is also provided with an air extraction port, which is located in the middle of the body, biased towards the inlet guide end.

[0005] Currently, smoke removal devices draw all the smoke and dust into the device's interior, resulting in poor smoke and dust separation. The composite wires require the ambient temperature to drop before they can be cooled, leading to low cooling efficiency. Furthermore, the position of the guide tubes is fixed, making it impossible to quickly expand the number of guide tubes according to usage requirements, thus reducing the device's versatility and flexibility. Summary of the Invention

[0006] The purpose of this invention is to address the problems of poor smoke removal, poor cooling, poor device flexibility, and poor device versatility caused by smoke removal devices drawing all the smoke and dust into the device's interior, composite yarns requiring a decrease in ambient temperature to be cooled, and the fixed position of the guide tube. Therefore, this invention proposes a smoke removal and cooling device for the production of polyester-nylon composite yarns.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a smoke removal and cooling device for the production of polyester-nylon composite yarn, comprising a fixed frame, a condensation mechanism, and multiple sets of adsorption cooling mechanisms. The condensation mechanism is fixedly connected to the fixed frame, and the multiple sets of adsorption cooling mechanisms are inserted into the fixed frame and arranged in an array. The adsorption cooling mechanisms are respectively provided with an inlet and an outlet at opposite ends. The adsorption cooling mechanisms are connected to the condensation mechanism through a first vacuum pump and a second vacuum pump.

[0008] As a further description of the above technical solution:

[0009] The adsorption cooling mechanism includes an inner tube, an outer tube, and multiple cold air pipes. The inlet and outlet are respectively connected to opposite ends of the inner tube. The outer tube is sleeved on the inner tube, and a sealed smoke chamber is formed between the outer tube and the inner tube. The inner tube has multiple first through holes that penetrate the inner tube and connect to the smoke chamber. The smoke chamber is connected to the first vacuum pump through a first pipe. The multiple cold air pipes are embedded in the inner wall of the inner tube. One end of each cold air pipe is closed, and the other end of each cold air pipe connects to the second vacuum pump. The cold air pipes have multiple second through holes. A filter is installed inside the smoke chamber.

[0010] As a further description of the above technical solution:

[0011] Multiple first through holes are located between the inlet and the filter.

[0012] As a further description of the above technical solution:

[0013] The other end of the multiple cooling pipes is connected to the annular ring, and the cooling pipes are connected to the annular ring. The annular ring is connected to the second vacuum pump through a second pipe.

[0014] As a further description of the above technical solution:

[0015] The multiple cooling pipes are arranged in a ring array.

[0016] As a further description of the above technical solution:

[0017] The inner tube is wrapped with a heat insulation layer, which is located inside the smoke chamber and between the first through hole and the outlet.

[0018] As a further description of the above technical solution:

[0019] The condensation mechanism includes a housing and a condenser. The housing is fixedly connected to the fixed frame, and the condenser is fixedly installed on the housing. The housing has two compartments, each of which is connected to the outside through an air inlet and an air outlet.

[0020] As a further description of the above technical solution:

[0021] The first vacuum pump is connected to the air inlet of one of the chambers, and the second vacuum pump is connected to the air outlet of the other chamber.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, the adsorption cooling mechanism can be extended by inserting it into the fixed frame. The position and number of the adsorption cooling mechanism can be adjusted according to the usage requirements, which greatly improves the flexibility of the device and makes it highly versatile.

[0024] 2. In this invention, the air cooled by the condensation mechanism outside the device is sent to multiple cold air pipes by the second vacuum pump. The cold air in the cold air pipes is released into the inner pipe and rapidly cools the composite filament. The first vacuum pump generates negative pressure in the smoke chamber. The negative pressure acts on the inner pipe through the first through hole, causing the smoke in the inner pipe to enter the smoke chamber. After the smoke is filtered by the filter, the smoke is sent to the condensation mechanism by the first vacuum pump for cooling and discharge. This ensures that each set of adsorption and cooling mechanisms provides an independent smoke removal and cooling channel for the composite filament, resulting in good smoke removal and cooling effects.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-7 The present invention provides a technical solution: a smoke removal and cooling device for the production of polyester-nylon composite yarn, comprising a fixed frame 1, a condensation mechanism 2 and multiple sets of adsorption cooling mechanisms 3, wherein the condensation mechanism 2 is fixedly connected to the fixed frame 1, and the multiple sets of adsorption cooling mechanisms 3 are inserted into the fixed frame 1 and arranged in an array, wherein the adsorption cooling mechanisms 3 are respectively provided with an inlet 4 and an outlet 5 at opposite ends, and the adsorption cooling mechanisms 3 are respectively connected to the condensation mechanism 2 through a first vacuum pump 6 and a second vacuum pump 7;

[0036] The adsorption cooling mechanism 3 includes an inner tube 31, an outer tube 32, and multiple cold air pipes 33. The inlet 4 and the outlet 5 are respectively connected to the opposite ends of the inner tube 31. The outer tube 32 is sleeved on the inner tube 31, and a sealed smoke chamber 8 is formed between the outer tube 32 and the inner tube 31. The inner tube 31 has multiple first through holes 9 that penetrate the inner tube 31 and are connected to the smoke chamber 8. The smoke chamber 8 is connected to the first vacuum pump 6 through a first pipe 10. The multiple cold air pipes 33 are embedded in the inner wall of the inner tube 31. One end of each cold air pipe 33 is closed, and the other end is connected to the second vacuum pump 7. The cold air pipes 33 have multiple second through holes 11. A filter 12 is provided inside the smoke chamber 8.

[0037] Multiple first through holes 9 are located between the inlet 4 and the filter 12 to ensure that smoke and dust are drawn into the smoke chamber 8 and fully filtered;

[0038] The other end of the multiple cooling pipes 33 is connected to the annular ring 13, and the cooling pipes 33 are connected to the annular ring 13. The annular ring 13 is connected to the second vacuum pump 7 through the second pipe 14. The multiple cooling pipes 33 are arranged in a ring array to facilitate rapid and uniform cooling of the composite filament.

[0039] The inner tube 31 is wrapped with a heat insulation layer 15, which is located inside the smoke chamber 8 and between the first through hole 9 and the outlet 5, so that the temperature of the smoke does not interfere with the temperature inside the cooling tube.

[0040] The condensation mechanism 2 includes a housing 21 and a condenser 22. The housing 21 is fixedly connected to the fixed frame 1, and the condenser 22 is fixedly installed on the housing 21. The housing 21 is provided with two chambers 16. Each chamber 16 is connected to the outside through an air inlet 17 and an air outlet 18. Using a single condenser 22, the air entering the inner tube 31 can be cooled, and the filtered smoke and dust can also be cooled.

[0041] The first vacuum pump 6 is connected to the air inlet 17 of one of the chambers 16, and the second vacuum pump 7 is connected to the air outlet 18 of the other chamber 16.

[0042] Working principle: First, determine the number of adsorption cooling mechanisms 3 according to usage requirements. Insert the outer tube 32 of the adsorption cooling mechanism 3 into the fixed frame 1. Connect the first pipe 10 to the first vacuum pump 6 and the second pipe 14 to the second vacuum pump 7. Second, insert the composite wire from the inlet 4 into the inner tube 31 and then pull it out from the outlet 5. Turn on the first vacuum pump 6 and the second vacuum pump 7. The second vacuum pump 7 generates negative pressure on one of the chambers 16 in the housing 21. Air enters the chamber 16 from the corresponding air inlet 17. Under the cooling effect of the condenser 22, the air temperature in the chamber 16 gradually decreases. The second vacuum pump 7... Cold air is sent through the annular ring 13 to multiple cooling pipes. The cold air in the cooling pipes enters the inner tube 31 through the second through hole 11, providing sufficient and rapid cooling to the composite filament passing through the inner tube 31. Finally, the first vacuum pump 6 generates negative pressure on the smoke chamber 8. The negative pressure acts on the inner tube 31 through the first through hole 9. The smoke dust passing through the inner tube 31 is drawn into the smoke chamber 8 through the first through hole 9. The smoke dust is filtered by the filter 12 in the smoke chamber 8. The filtered smoke dust becomes clean gas and enters another chamber 16 in the housing 21. Under the cooling effect of the condenser 22, the air in the chamber 16 is cooled and discharged from the outlet 18.
