[0001] The present invention belongs to the technical field of fecal drainage devices, and more specifically, relates to an antistatic polyester fiber production device. Background Art

[0002] During the production process of polyester fibers, they contain a relatively high amount of moisture, which may come from raw materials, additives during the production process, or environmental humidity, etc. If not dried, this moisture may affect the performance and quality of the fibers. Drying can effectively remove the moisture in the fibers to reach the required dryness level. Therefore, there is a drying process in the polyester fiber production process. Existing drying equipment achieves the drying purpose by passing polyester fibers through the drying equipment. However, existing drying equipment has problems such as slow drying efficiency and shrinkage and deformation of polyester fibers during the drying process. For this reason, an antistatic polyester fiber production device is proposed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an antistatic polyester fiber production device that can overcome or at least partially solve the above problems.

[0004] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: an antistatic polyester fiber production device, including a box body, and further including: two groups of connection mechanisms rotatably connected inside the box body, the connection mechanisms include a first drying drum, a second drying drum, and a third drying drum respectively rotatably connected inside the box body. The polyester fiber cloth penetrates into the box body from the outside of one side of the box body and sequentially bypasses each group of the connection mechanisms, and then exits from the other side of the box body; air outlet holes are circumferentially formed on the outer circumferences of the first drying drum, the second drying drum, and the third drying drum; air inlet pipes are respectively arranged in the first drying drum, the second drying drum, and the third drying drum. An eight-shaped baffle is fixedly connected to the outer circumference of the air inlet pipe, and end plates are fixedly connected to both ends of the eight-shaped baffle. The eight-shaped baffle and the end plates respectively form a gas guiding cavity in the first drying drum, the second drying drum, and the third drying drum. The gas guiding cavities in the first drying drum and the third drying drum face the top of the box body, the gas guiding cavity in the second drying drum faces the bottom of the box body, and an air outlet groove is formed on the outer circumference of the air inlet pipe, and the air outlet groove is communicated with the gas guiding cavity; air flow guiding areas are respectively located between the first drying drum and the second drying drum and between the second drying drum and the third drying drum to enable the air flow to pass through the polyester fiber cloth.

[0005] Preferably, L-shaped frames are symmetrically and fixedly connected to the inner wall of the box body. A sealed first chamber is formed between the L-shaped frames and the inner wall of the box body. The first drying drum and the third drying drum in the two connection mechanisms are respectively located in the two first chambers; a first opening is formed on the L-shaped frame for the polyester fiber to pass out of the first chamber.

[0006] Preferably, an N-shaped frame is fixedly connected to the bottom surface of the box body. A sealed second chamber is formed between the N-shaped frame and the box body. The second drying drums in the two connection mechanisms are both located in the second chamber; second openings are formed on both sides of the N-shaped frame for the polyester fiber to pass through the N-shaped frame, and the first opening and the second opening are arranged oppositely.

[0007] Preferably, a first baffle is fixedly connected between the L-shaped frame and the N-shaped frame. An installation box is fixedly connected to the top wall of the box body. An air outlet pipe is installed on the installation box. An air flow guiding area is formed between the L-shaped frame, the first baffle and the N-shaped frame for the air flow to flow towards the installation box in the air flow guiding area.

[0008] Preferably, a heat storage chamber is formed in the installation box. The air outlet pipe leads to the heat storage chamber. An air inlet groove is formed on the surface of the installation box close to the N-shaped frame, and the air inlet groove is communicated with the air flow guiding area.

[0009] Preferably, a connecting pipe is arranged below the polyester fiber cloth. A nozzle is installed on the connecting pipe. The nozzle is inclined upwards for spraying an antistatic agent onto the polyester fiber cloth.

[0010] Furthermore, installation plates are symmetrically and fixedly connected in the box body. A plurality of sliding rods are slidably connected to the installation plates at equal intervals. One ends of the plurality of sliding rods are connected by a connecting plate. A spring is connected between the installation plate and the connecting plate. One end of the sliding rod is fixedly connected with a pushing plate. The pushing plate is located on one side of the polyester fiber cloth for reciprocally pushing the polyester fiber cloth through the pushing plate when the sliding rod reciprocally slides, so as to disturb the air flow in the air flow guiding area.

[0011] Preferably, a rotating shaft is rotatably connected in the installation box. A cam is fixedly connected to the end of the rotating shaft. The cam is used for reciprocally pushing the connecting plate, and a sleeve is sleeved on the rotating shaft.

[0012] An antistatic polyester fiber, including the above-mentioned antistatic polyester fiber production equipment, comprises the following components and their parts by weight: 5-10 parts of nano-tin dioxide conductive powder, 20-40 parts of surface treatment agent; the flame-retardant polyester is prepared from a phosphorus-based flame retardant, terephthalic acid and ethylene glycol, and the nano-tin dioxide conductive powder is prepared from SnCl·5H2O and SbCl3. The obtained polyester fiber has good antistatic property and meets the detection requirements.

[0013] An antistatic polyester fiber production process mainly includes the following steps: S1. Pretreatment of raw materials: Processing through a polymerization reaction; S2. Mixing of raw materials: Mixing and processing the raw materials through a mixing device; S3. Preparation of melt: Melting the raw materials; S4. Filament forming process: Spinning the melted raw materials through a spinning device; S5. Spraying process: Spraying an antistatic agent through a spraying device; S6. Drying treatment: Drying through a drying device; S7. Oiling treatment: Conducting an oiling treatment through an oiling device; S8. Drawing treatment; Conducting a drawing treatment through a drawing device; S9. Winding treatment: Winding the antistatic polyester fiber through a winding device.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. In this antistatic polyester fiber production equipment, by setting two groups of connecting mechanisms, the drying operation can be carried out on two polyester fiber cloths simultaneously. And through the position distribution of the two polyester fiber cloths in the box, compared with the existing drying equipment, the drying efficiency can be further improved. The first opening and the second opening are arranged oppositely. Therefore, when the hot air is discharged from the first opening and the second opening, a hot air convection can be formed in the air flow guiding area. This enables the convective hot air to dry the polyester fiber cloth passing through the air flow guiding area in a diffused manner. Moreover, the setting of the air flow guiding area can also improve the adhesion effect when the nozzle sprays the antistatic agent on the surface of the polyester fiber cloth; 2. In this antistatic polyester fiber production equipment, the pipelines of the external heating blower are respectively connected to the air inlet pipes to pump hot air into the air inlet pipes; after the hot air enters the air inlet pipes, it is discharged into the air guiding cavity from the air outlet grooves. The setting of the air guiding cavity can enable the hot air to always blow onto the polyester fiber cloth through the air outlet holes during the rotation of the first drying drum, the second drying drum, and the third drying drum, thereby efficiently drying the polyester fiber cloth; and the gas discharged from the air outlet holes will respectively gather in the two first chambers and the second chamber, which enables the heat to concentrate and dry the polyester fiber cloth again; 3. For this antistatic polyester fiber production equipment, the first opening and the second opening are arranged oppositely. Therefore, when the hot air in the first chamber and the second chamber is discharged from the first opening and the second opening, a hot air convection can be formed in the air flow guiding area, which enables the convective hot air to dry the polyester fiber cloth passing through the air flow guiding area in a diffused manner. Since there is an air outlet pipe, when the hot air collides and convects in the air flow guiding area, it will move upward along the air flow guiding area and be discharged outside the box through the air outlet pipe, enabling the hot air in the box to flow, thereby improving the drying effect on the polyester fiber cloth. 4. For this antistatic polyester fiber production equipment, this device is provided with a nozzle. By spraying an antistatic agent onto the polyester fiber cloth, and the nozzle is arranged in the air flow guiding area. This enables the antistatic agent sprayed by the nozzle to quickly adhere to the polyester fiber cloth when the hot air collides in the air flow guiding area. And since the air flow in the air flow guiding area moves upward, and the nozzle is arranged below the polyester fiber cloth, the upward moving air flow can drive the antistatic agent to adhere to the polyester fiber cloth. Therefore, the adhesion between the antistatic agent and the polyester fiber cloth can be improved, further enhancing the antistatic performance of the polyester fiber cloth. 5. For this antistatic polyester fiber production equipment, the rotating shaft is driven to rotate by a motor. To avoid the motor being too close to the box, which may lead to an increase in heat and affect its working performance, the motor can be installed away from the box and connected to the top of the rotating shaft through a chain. The motor drives the rotating shaft to rotate, and the cam reciprocally pushes the sliding rod. One end of the sliding rod reciprocally pushes the polyester fiber cloth located in the upper layer. There is a space formed between the two polyester fiber cloths. Therefore, when pushing the polyester fiber cloth, the gas in the space is further disturbed, which makes the adhesion effect between the antistatic agent and the polyester fiber cloth better.

A sealed first chamber 13 is formed between the L-shaped frames 12 and the inner wall of the box body 1. The first drying drum 11 and the third drying drum 3 in the two sets of connecting mechanisms are respectively located in the two first chambers 13; first openings 14 are formed on the L-shaped frames 12 for the polyester fiber to penetrate out from the first chamber 13; An N-shaped frame 2 is fixedly connected to the bottom surface of the box body 1. A sealed second chamber 22 is formed between the N-shaped frame 2 and the box body 1. The second drying drums 21 in the two sets of connecting mechanisms are all located in the second chamber 22; second openings 23 are formed on both sides of the N-shaped frame 2 for the polyester fiber to pass through the N-shaped frame 2. The first openings 14 and the second openings 23 are arranged oppositely; A first baffle 4 is fixedly connected between the L-shaped frame 12 and the N-shaped frame 2. An installation box 5 is fixedly connected to the top wall of the box body 1. An air outlet pipe 54 is installed on the installation box 5. An air flow guiding area 41 is formed among the L-shaped frame 12, the first baffle 4, and the N-shaped frame 2, and the second baffle 51 on the installation box 2 can further guide the air flow, for enabling the air flow to flow towards the direction close to the installation box 5 in the air flow guiding area 41; A heat storage cavity 53 is formed in the installation box 5, an air outlet pipe 54 leads to the heat storage cavity 53, an air inlet groove 52 is formed on one side of the installation box 5 close to the N-type frame 2, and the air inlet groove 52 communicates with the air flow guiding area 41; A connecting pipe 7 is arranged below the polyester fiber cloth 10, a nozzle 71 is installed on the connecting pipe 7, and the nozzle 71 is inclined upward for spraying antistatic agent onto the polyester fiber cloth 10; Mounting plates 62 are symmetrically and fixedly connected in the box body 1, a plurality of sliding rods 63 are slidably connected to the mounting plates 62 at equal intervals, one ends of the plurality of sliding rods 63 are connected by a connecting plate 65, a spring 64 is connected between the mounting plate 62 and the connecting plate 65, and one end of the sliding rod 63 is fixedly connected with a pushing plate 66. The pushing plate 66 is located on one side of the polyester fiber cloth 10 and is used for reciprocally pushing the polyester fiber cloth 10 through the pushing plate 66 when the sliding rod 63 reciprocally slides, so as to disturb the air flow in the air flow guiding area 41; A rotating shaft 6 is rotatably connected in the installation box 5, a cam 61 is fixedly connected to the end of the rotating shaft 6, the cam 61 is used for reciprocally pushing the connecting plate 65, and a sleeve 50 is sleeved on the rotating shaft 6; When the device is in use, two polyester fiber cloths 10 are passed through the box body 1; The pipelines of the external heating blower are respectively communicated with the air inlet pipes 15 for pumping hot air into the air inlet pipes 15; After the hot air enters the air inlet pipe 15, it is discharged into the air guiding cavity 153 from the air outlet groove 150. The arrangement of the air guiding cavity 153 enables the hot air to always blow onto the polyester fiber cloth 10 through the air outlet holes 110 during the rotation of the first drying drum 11, the second drying drum 21, and the third drying drum 3, so as to efficiently dry the polyester fiber cloth 10; The gases discharged from the air outlet holes 110 will respectively gather in the two first chambers 13 and the second chamber 22, so that the heat can be concentrated to dry the polyester fiber cloth 10 again; The first opening 14 and the second opening 23 are arranged oppositely. Therefore, when the hot air in the first chamber 13 and the second chamber 22 is discharged from the first opening 14 and the second opening 23, a hot air convection can be formed in the air flow guiding area 41, so that the convective hot air can dry the polyester fiber cloth 10 passing through the air flow guiding area 41 in a diffused state; Due to the arrangement of the air outlet pipe 54, when the hot air convects and collides in the air flow guiding area 41, it will move upward along the air flow guiding area 41 and be discharged out of the box body 1 through the air outlet pipe 54, so that the hot air in the box body 1 can flow, thereby improving the drying effect on the polyester fiber cloth 10; In one embodiment, the air outlet pipe 54 can be connected to an external exhaust fan to assist in improving the air flow in the box body 1 through the exhaust fan; The device is provided with a nozzle 71. By spraying an antistatic agent onto the polyester fiber cloth 10, and the nozzle 71 is arranged in the air flow guiding area 41. When the hot air collides in the air flow guiding area 41, it can make the antistatic agent sprayed by the nozzle 71 quickly adhere to the polyester fiber cloth 10. And because the air flow in the air flow guiding area 41 moves upward, and the nozzle 71 is arranged below the polyester fiber cloth 10, the upward moving air flow can drive the antistatic agent to adhere to the polyester fiber cloth 10. Therefore, the adhesion between the antistatic agent and the polyester fiber cloth 10 can be improved, and further improve the antistatic performance of the polyester fiber cloth 10; Furthermore, the heat storage cavity 53 can be used for heat storage. Through the setting of the sleeve 50, the heat storage cavity 53 is not connected to the air inlet groove 52 and the air outlet pipe 54. When the hot air passes through the installation box 5, the heat can be concentrated in the heat storage cavity 53, which makes the heat distribution in the box body 1 more uniform; Secondly, heat storage ceramics can be placed in the heat storage cavity 53, which can further improve the heat storage capacity of the heat storage cavity 53; The rotating shaft 6 is driven to rotate by a motor. In order to prevent the motor from being too close to the box body 1, which may cause an increase in heat and affect the working performance, the motor can be installed far away from the box body 1 and connected to the top end of the rotating shaft 6 through a chain. The motor drives the rotating shaft 6 to rotate, and the cam 61 reciprocally pushes the sliding rod 63. The push plate 66 at one end of the sliding rod 63 reciprocally pushes the upper polyester fiber cloth 10. There is a space formed between the two polyester fiber cloths 10. Therefore, when pushing the polyester fiber cloth 10, the gas in the space is further disturbed, which makes the adhesion effect between the antistatic agent and the polyester fiber cloth 10 better.

[0019] Example 2: Refer to Figures 1 - 9 An antistatic polyester fiber production process mainly includes the following steps: Successively carry out raw material pretreatment, raw material mixing, melt preparation, filament forming process, spraying process, drying treatment, oiling treatment, stretching treatment, winding treatment; among them, the polyester fiber cloth 10 obtained through the spraying process in step S5 meets the antistatic detection requirements, and the test results refer to Figures 10 - 13 .

[0020] By setting two groups of connecting mechanisms in the present invention, the drying operation can be carried out on two polyester fiber cloths 10 at the same time. And through the position distribution of the two polyester fiber cloths 10 in the box body 1, compared with the existing drying equipment, the drying efficiency can be further accelerated. The first opening 14 and the second opening 23 are arranged oppositely. Therefore, when the hot air is discharged from the first opening 14 and the second opening 23, a hot air convection can be formed in the air flow guiding area 41. This makes the convective hot air dry the polyester fiber cloth 10 passing through the air flow guiding area 41 in a diffused state. And the setting of the air flow guiding area 41 can also improve the adhesion effect when the nozzle 71 sprays the antistatic agent onto the surface of the polyester fiber cloth 10.

[0021] The above are only the preferred embodiments of the present invention, and there is no restriction on the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention can make some changes or modifications to equivalent embodiments by using the technical content prompted above within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
