Description

Technical Field

[0001] This invention relates to the field of chemical fiber machinery technology, specifically to a sliding sealing door for chemical fiber production equipment. Background Technology

[0002] In the chemical fiber industry, post-processing of viscose, Lyocell, or vinylon staple fibers is a crucial step before the finished fiber product. The post-processing refining machine is one of the important unit machines, used to perform processes such as washing, desulfurization, bleaching, and oiling on the cut staple fibers to give them good whiteness and spinnability. An openable sliding door is installed on the upper frame of the refining machine; when the door is open, the rollers can be disassembled, and the equipment can be quickly cooled.

[0003] Traditional refining machines for viscose, Lyocell, or vinylon staple fiber post-processing use cylinders for their top sliding doors. During production and maintenance, cylinder failure can cause the door to suddenly close, posing a safety hazard. Furthermore, each process zone of the refining machine only has a door on the operating side, and these doors are only about the width of the process zone, providing limited operating space. Traditional refining machine sliding doors are constructed from stainless steel rectangular tubing welded from thin stainless steel sheets, with each door weighing 200-280 kg, making installation and disassembly inconvenient. In conclusion, traditional refining machine sliding doors no longer meet users' increasingly demanding requirements for safety and convenience.

[0004] Therefore, the present invention provides a sliding sealing door for chemical fiber production equipment to solve the above problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a sliding sealing door for chemical fiber production equipment, so as to solve the problem that the traditional refining machine sliding door in the above background art is made of stainless steel rectangular tube and stainless steel thin plate welded together, and the weight of a single sliding door is 200-280Kg, which makes installation and disassembly inconvenient.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A sliding sealing door for chemical fiber production equipment includes a sealing door frame composed of four L-shaped angle steels. A lower sliding door slide plate is fixedly installed on the bottom surface of the inner side of the sealing door frame near its inner edge. A lower sliding door is slidably installed on the lower sliding door slide plate. A raised square steel is fixedly installed on the bottom surface of the inner side of the sealing door frame outside the lower sliding door slide plate. An upper sliding door slide plate is fixedly installed on the top of the raised square steel. An upper sliding door is slidably installed on the top of the upper sliding door slide plate above the lower sliding door. The bottom surface of the upper sliding door is in contact with the top surface of the lower sliding door. Both the lower and upper sliding doors are equipped with a sliding drive mechanism.

[0008] Preferably, both the lower sliding door and the upper sliding door consist of a door frame square steel, a door panel square steel, and a door panel. The door frame square steel consists of four steel bars spliced ​​together to form a rectangle. A door panel square steel is fixedly installed between two of the door frame square steel bars, so that the inner side of the door frame square steel is divided into multiple door panel grooves.

[0009] Preferably, a door panel support plate is fixedly installed at the bottom of each door panel groove, and the door panels are all installed on the door panel support plate in the door panel groove.

[0010] Preferably, the translation drive mechanism includes a translation rack, a translation motor, and a translation gear. A translation rack is fixedly installed on the top surface of one of the horizontal ends of the lower and upper sliding door slides. Translation motor slots are opened at both ends of the side of the lower and upper sliding doors facing the corresponding translation racks. A motor plate is fixedly installed on the outside of each translation motor slot. A translation motor located inside the translation motor slot is installed on each motor plate. The rotation shaft of each translation motor passes through the corresponding motor plate and is coaxially fixedly installed with a translation gear that meshes with the corresponding translation rack.

[0011] Preferably, both the lower sliding door and the upper sliding door have batteries installed inside the square steel frame of the door panel on which the sliding motor is installed, and the sliding motors installed on the lower sliding door and the upper sliding door are electrically connected to the corresponding batteries.

[0012] Preferably, charging plugs are fixedly installed on both the left and right sides of the lower sliding door and the upper sliding door, and the charging plugs are electrically connected to the battery. Charging bases are fixedly installed on both the left and right inner sides of the sealed door frame.

[0013] Preferably, the lower sliding door slide plate and the upper sliding door slide plate are made of polytetrafluoroethylene.

[0014] Preferably, air suction pipes are fixedly installed on all four outer sides of the sealed door frame, each air suction pipe has an air suction hole facing the middle of the sealed door frame, and multiple air suction pipes are connected to an exhaust pump.

[0015] The beneficial effects of this invention are as follows: by replacing the original hinged sealing door with a sliding sealing door, the situation of large load and safety hazards when the hydraulic cylinder is opened and closed is avoided. Each sliding door is driven by two sliding gears driven synchronously by a sliding motor, thereby driving the two sliding doors to open and close. When the sliding door is opened, the air intake pipes around the sealing door frame can absorb the harmful gases that drift out from the open door, preventing them from spreading into the working environment.

[0025] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 8As will be clearly shown in the detailed description of the embodiments, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] As attached Figure 1-8 As shown, a sliding sealing door for chemical fiber production equipment includes a sealing door frame 1, which can be installed on the top of a sealed enclosure. The sealing door frame 1 is composed of four angle steels with an "L"-shaped cross-section, which can be connected by welding. A lower sliding door slide plate 3 is fixedly installed on the bottom surface of the inner side of the sealing door frame 1 near its inner edge. The top surface of the lower sliding door slide plate 3 has a countersunk hole and can be fixed to the sealing door frame 1 by screws or bolts. A lower sliding door 4 is slidably installed on the lower sliding door slide plate 3. A raised square steel 5 located outside the lower sliding door slide plate 3 is fixedly installed on the bottom surface of the inner side of the sealing door frame 1. The raised square steel 5 can be welded to the sealing door frame 1. An upper sliding door slide plate 6 is fixedly installed on the top of the raised square steel 5. The top surface of the upper sliding door slide plate 6 has a countersunk hole and can be fixed to the top by screws or bolts. The upper sliding door 7, located above the lower sliding door 4, is slidably mounted on the top of the upper sliding door slide plate 6, with its bottom surface touching the top surface of the lower sliding door 4. Both the lower sliding door 4 and the upper sliding door 7 are equipped with a sliding drive mechanism. The lower sliding door 4 and the upper sliding door 7 can seal the inside of the sealing door frame 1, thus isolating the chemical equipment inside the sealed room from the outside. The high temperature and harmful gases generated by the chemical equipment can be discharged through the exhaust vent, avoiding harm to the human body and pollution of the working environment. When it is necessary to feed materials into the chemical equipment, the other side of the lower sliding door 4 or the upper sliding door 7 can be moved by the sliding drive mechanism. This can replace the existing method of opening the sealing door upward with a hydraulic cylinder, avoiding the large load on the hydraulic cylinder when opening the sealing door and the potential safety hazards.

[0028] Both the lower sliding door 4 and the upper sliding door 7 consist of a door panel frame square steel 8, a door panel square steel 9, and a door panel 10. The door panel frame square steel 8 consists of four steel pieces spliced ​​together to form a rectangle. The four door panel frame square steel 8 are fixed together by welding. A door panel square steel 9 is fixedly installed between two of the door panel frame square steel 8. The door panel square steel 9 is fixed inside the door panel frame square steel 8 by welding, so that the inner side of the door panel frame square steel 8 is divided into multiple door panel grooves 11.

[0029] A door panel support plate 12 is fixedly installed at the bottom of each door panel groove 11. The door panels 10 are all installed on the door panel support plate 12 inside the door panel groove 11. The door panels 10 can be placed inside the door panel groove 11. The door panel support plate 12 can provide support for lifting the door panels 10. Then, screws are used to fix the door panels 10 to the door panel support plate 12.

[0030] The translation drive mechanism includes a translation rack 14, a translation motor 15, and a translation gear 16. A translation rack 14 is fixedly installed on the top surface of one of the horizontal ends of the lower sliding door slide plate 3 and the upper sliding door slide plate 6. The translation rack 14 can be fixed with screws. Translation motor slots 17 are opened at both ends of the side of the lower sliding door 4 and the upper sliding door 7 facing the corresponding translation rack 14. The translation motor slots 17 are opened on the outer surface of the door frame square steel 8. A motor plate 18 is fixedly installed on the outer side of each translation motor slot 17. The motor plate 18 can be fixedly installed on the outer surface of the door frame square steel 8 with screws and can cover the translation motor slot 17. A translation motor 15 is installed on each motor plate 18, located inside the translation motor slot 17. The translation motor 15 can be a geared motor. After the motor plate 18 is installed on the door frame square steel 8, the translation motor 15 can be hidden within the translation slot. Inside the motor slot 17, the rotating shaft of each of the translation motors 15 passes through the corresponding motor plate 18, and a translation gear 16 that meshes with the corresponding translation rack 14 is coaxially fixedly installed. When the two translation motors 15 on the lower sliding door 4 or the upper sliding door 7 are started simultaneously, the two translation gears 16 can rotate synchronously, thereby driving the lower sliding door 4 or the upper sliding door 7 to move and realize the opening and closing of the sealing door. Alternatively, a translation motor 15 can be set on both the lower sliding door 4 and the upper sliding door 7 and hidden inside the translation motor slot 17. A synchronous pulley set is connected between the two translation gears 14. When the translation motor 15 starts and drives one of the translation gears to rotate, the other translation gear 14 can be driven to rotate synchronously through the synchronous pulley set, avoiding the rotation delay between the two translation motors 15, which would cause the two translation gears 14 to rotate asynchronously and jam, preventing the sliding door from moving.

[0031] Both the lower sliding door 4 and the upper sliding door 7 have batteries 19 installed inside the square steel frame of the door panel frame on which the sliding motors 15 are installed. The sliding motors 15 installed on the lower sliding door 4 and the upper sliding door 7 are electrically connected to the corresponding batteries 19. The batteries 19 can provide power to the sliding motors 15, and the sliding motors 15 can be remotely connected to a controller. The controller can simultaneously control the two sliding motors 15 on the lower sliding door 4 or the upper sliding door 7.

[0032] Charging plugs 20 are fixedly installed on both the left and right sides of the lower sliding door 4 and the upper sliding door 7. Charging bases 21 are fixedly installed on both the left and right inner sides of the sealed door frame 1. The charging plugs 20 are electrically connected to the battery 19. When the lower sliding door 4 and the upper sliding door 7 are closed at either end of the sealed door panel 1, the charging plugs 20 can connect to the charging bases 21 to charge the battery 19. When the lower sliding door 4 and the upper sliding door 7 are open, the charging plugs 20 are separated from the charging bases 21, and the charging of the battery 19 stops.

[0033] The lower sliding door slide plate 3 and the upper sliding door slide plate 6 are made of polytetrafluoroethylene (PTFE). PTFE is heat-resistant, has an extremely low coefficient of friction, and an extremely smooth surface, which reduces lubrication operations. Using it as the guide rail for the lower sliding door 4 and the upper sliding door 7 can reduce the friction with the support of the sealed door frame 1.

[0034] Suction pipes 22 are fixedly installed on the four outer sides of the sealed door frame 1. Each suction pipe 22 has a suction hole facing the middle of the sealed door frame 1. Multiple suction pipes 22 are connected to an exhaust pump. Turning on the exhaust pump can provide suction to the multiple suction pipes 22. When the lower sliding door 4 or the upper sliding door 7 is opened, the high temperature and harmful gases inside the sealed room can diffuse to the outside through the door opening. The suction pipes 22 around the sealed door frame 1 can absorb the diffused gas through multiple suction holes to prevent it from continuing to diffuse into the working environment.
