Description

Technical Field

[0001] This application relates to flux-cored wire technology, and more particularly to a powder drying device for flux-cored wire production. Background Technology

[0002] In the production process of flux-cored welding wire, the flux powder needs to be dried and the water of crystallization removed before it is filled with flux powder.

[0003] Currently, medicinal powders are typically dried using a drying oven. The process involves first loading the powder into multiple trays, then placing each tray onto a shelf inside the drying oven. The oven door is then closed, and the drying process begins. Once drying is complete, the door is opened, and the trays are removed one by one to collect the powder. However, the trays remain quite hot after drying. To avoid burns to workers handling the trays, they are usually allowed to cool down before being removed. Furthermore, the trays cool down slowly within the drying oven, resulting in a lengthy drying process and low efficiency. Utility Model Content

[0004] This application provides a powder drying device for flux-cored welding wire production, which solves the problems of long drying time and low drying efficiency in existing drying boxes.

[0005] This application provides a powder drying device for producing flux-cored welding wire, including a drying box and a placement structure I. The drying box is a hollow structure with one end open, and there are two placement structures I.

[0006] The placement structure I includes a placement frame, which is provided with multiple detachable trays. The bottom of the placement frame is provided with a set of casters, and one end of the placement frame is provided with a door that slides vertically thereto.

[0007] Both doors can simultaneously close the opening of the drying oven and are detachably and fixedly connected to the drying oven.

[0008] The drying oven has a lifting platform that can move up and down on the side of the opening end, and the upper end of the lifting platform can be flush with the upper end of the ground.

[0009] Optionally, it also includes two placement structures II, the structures of which are the same as those of the placement structure I;

[0010] Two placement structures I and two placement structures II alternately enter the drying oven.

[0011] Optionally, a support platform is fixed to the lower part of the opening end of the drying box, and the upper end of the support platform is flush with the lower inner end of the drying box.

[0012] The upper end of the drying oven is equipped with a pressure plate that can move up and down. The pressure plate and the support platform can simultaneously press and seal the two oven doors.

[0013] Optionally, both ends of the pressure plate are fixed with electric push rods, and the electric push rods are fixed to the outer wall of the drying oven.

[0014] Optionally, one end of the placement rack has two symmetrically distributed mounting slots, and vertically distributed sliding rods are fixed inside the mounting slots. A slider is fitted on the sliding rod and slidably connected to it and fixed to the box door.

[0015] The slide bar is fitted with a spring that is connected to both the slider and the mounting groove. When the spring is in a free state, the lower end of the box door is located above the lower end of the moving wheel assembly.

[0016] Optionally, it also includes a groove set on the ground and adapted to the lifting platform, with a bottom groove in the middle of the groove, and a scissor lifting mechanism inside the bottom groove, and the scissor lifting mechanism is connected to the lifting platform and drives the lifting platform to move up and down.

[0017] Optionally, the tray is plugged into the placement rack.

[0018] The flux-cored welding wire production powder drying device provided in this application comprises a drying chamber with one open end and two placement structures I. Each placement structure I includes a placement rack with multiple detachable trays. The bottom of the placement rack is equipped with casters.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0028] like Figures 1-5 As shown:

[0029] An embodiment of this application provides a powder drying device for producing flux-cored welding wire, including a drying box 1 and a placement structure I2. The drying box 1 is a hollow structure with one end open, and there are two placement structures I2.

[0030] In this embodiment, the drying oven 1 is existing technology and will not be described in detail.

[0031] The placement structure I2 includes a placement frame 201, which is provided with multiple detachable trays 204. The bottom of the placement frame 201 is provided with a set of movable wheels 205, which consists of four universal wheels. The four universal wheels are respectively installed at the four corners of the bottom of the placement frame 201. One end of the placement frame 201 is provided with a box door 206 that is slidably connected to it.

[0032] The two doors 206 can simultaneously close the opening of the drying chamber 1 and are detachably and fixedly connected to the drying chamber 1.

[0033] Furthermore, a column 101 is fixed at the middle of the opening end of the drying oven 1. When the door 206 closes the opening end of the drying oven 1, the rear end of the door 206 simultaneously contacts the front end of the drying oven 1 and the front end of the column 101.

[0034] The drying oven 1 has a vertically movable lifting platform 3 on the side of its opening end, and the upper end of the lifting platform 3 is flush with the upper end of the ground to facilitate the movement of the placement structure I2 between the ground and the lifting platform 3. Specifically, the lifting platform 3 is a rectangular plate structure.

[0035] Furthermore, a handle 207 is fixed to the front end of the box door 206 (that is, the outer end of the box door 206) to facilitate the movement and placement of structure I2 by staff.

[0036] In this embodiment, since the door 206 needs to move with the placement rack 201 and also needs to close the opening of the drying chamber 1, the lower end of the door 206 must be flush with the lower end of the caster wheel to completely close the opening of the drying chamber 1. However, when the lower end of the door 206 is flush with the lower end of the caster wheel, it will contact the upper end of the lifting platform 3 or the ground when the placement rack 201 is moved, resulting in greater resistance and making it inconvenient to move the placement rack 201. Therefore, after the placement rack 201 and the door 206 are slidably connected, when the placement rack 201 is moved, the door 206 is moved upward relative to the placement rack 201, so that the lower end of the door 206 is above the lower end of the caster wheel. In this way, the lower end of the door 206 will not contact the upper end of the lifting platform 3 or the ground, thus facilitating the movement of the placement rack 201.

[0037] In use, the operator holds handle 207, moves the two placement structures I2 to the loading position, removes the material tray 204, loads the powder to be dried into the material tray 204, and then installs the material tray 204 on the placement rack 201. Next, the two placement structures I2 are moved to the lifting platform 3, and the lifting platform 3 is moved up so that the upper end of the lifting platform 3 is flush with the lower inner end of the drying chamber 1. Then, the two placement racks 201 are pushed into the drying chamber 1. After the two placement racks 201 are fully inside the drying chamber 1, the two chamber doors 206 simultaneously close the opening of the drying chamber 1. The rear end of the chamber door 206 simultaneously contacts the front end of the drying chamber 1 and the front end of the column 101. After the chamber door 206 is fixedly connected to the drying chamber 1, the drying chamber 1 can be started for drying.

[0038] After drying is completed, the fixed connection between the door 206 and the drying chamber 1 is released. The operator holds the handle 207 and pulls the door 206 from the front end to move the two placement racks 201 onto the lifting platform 3. Then, the lifting platform 3 is lowered until it is level with the ground. The door 206 is pulled again to move the placement racks 201 to an empty position on the ground to cool the material trays 204 on the placement racks 201. After cooling is completed, the powder in the material trays 204 is collected, and the next batch of powder is dried.

[0039] The flux-cored wire production powder drying device provided in this application comprises a drying chamber 1 with one open end and two placement structures I2. Each placement structure I2 includes a placement rack 201 with multiple detachable trays 204. The bottom of the placement rack 201 is equipped with a set of casters 205. One end of the placement rack 201 has a door 206 that slides vertically thereto. Both doors 206 can simultaneously close the opening of the drying chamber 1 and are detachably fixedly connected to the drying chamber 1. The side of the opening of the drying chamber 1 is provided with a... The lifting platform 3 moves up and down, and the upper end of the lifting platform 3 can be flush with the upper end of the ground. After the medicine powder is dried, the staff can pull the door 206 from the outside of the door 206. The door 206 drives the placement rack 201 to move. With the cooperation of the lifting platform 3, the material tray 204 can be moved out of the drying box 1 for cooling. This not only improves the cooling speed of the material tray 204 and shortens the cooling time, but also prevents the staff from being burned when moving the placement rack 201, as the staff only comes into contact with the outside of the door 206.

[0040] In some embodiments of this application, two placement structures II4 are also included, the structures of which are the same as those of placement structure I2.

[0041] Among them, two placement structures I2 and two placement structures II4 alternately enter the drying oven 1.

[0042] In use, when the two placement structures I2 enter the drying chamber 1 to dry the medicinal powder, the material trays 204 of the two placement structures II4 are filled with medicinal powder and wait for drying. After the medicinal powder on the two placement structures I2 is dried, the two placement structures I2 are removed from the drying chamber 1, and the two placement structures II4 are sent into the drying chamber 1 for drying. When the medicinal powder on the two placement structures II4 is drying, the material trays 204 of the two placement structures I2 can be cooled, the dried medicinal powder can be collected, and the material trays 204 of the two placement structures I2 can be filled with medicinal powder again, thereby shortening the downtime of the drying chamber 1 and improving the drying efficiency of the drying chamber 1.

[0043] In some embodiments of this application, a support platform 102 is fixed to the lower part of the opening end of the drying oven 1, and the upper end of the support platform 102 is flush with the lower inner end of the drying oven 1, so that the placement rack 201 can enter the interior of the drying oven 1.

[0044] The upper end of the drying oven 1 is provided with a pressure plate 5 that can move up and down. The pressure plate 5 and the support platform 102 can simultaneously press and seal the two oven doors 206 of the drying oven 1.

[0045] In use, the placement rack 201 is fully inserted into the interior of the drying oven 1, and after the rear end of the oven door 206 contacts the front end of the drying oven 1 and the front end of the column 101, the pressure plate 5 is moved down. After the pressure plate 5 moves down, it first contacts the upper ends of the two oven doors 206, and then pushes the two oven doors 206 down relative to the placement rack 201. When the lower ends of the two oven doors 206 press tightly against the support table 102, the downward movement of the pressure plate 5 is stopped. At this time, the two oven doors 206 close the opening end of the drying oven 1, and the two oven doors 206 are clamped between the support table 102 and the pressure plate 5, fixing the oven doors 206 on the drying oven 1, thus realizing the detachable and fixed connection between the oven doors 206 and the drying oven 1.

[0046] In some embodiments of this application, electric push rods 6 are fixed at both ends of the pressure plate 5, and the electric push rods 6 are fixed on the outer wall of the drying oven 1.

[0047] In use, the two electric push rods 6 work synchronously. When the two electric push rods 6 shorten at the same time, the pressure plate 5 moves down. When the two electric push rods 6 extend at the same time, the pressure plate 5 moves up.

[0048] In some embodiments of this application, one end of the placement rack 201 has two symmetrically distributed mounting slots 208. Vertically distributed slide rods 209 are fixed inside the mounting slots 208. A slider 2010 is sleeved on the slide rod 209 and slidably connected to it and fixed to the box door 206.

[0049] A spring 2011 is fitted onto the slide rod 209, which is connected to both the slider 2010 and the mounting groove 208. When the spring 2011 is in a free state, the lower end of the door 206 is located above the lower end of the moving wheel assembly 205. Specifically, the lower end of the spring 2011 is fixedly connected to the slider 2010, and the upper end of the spring 2011 is fixedly connected to the upper end of the mounting groove 208.

[0050] In use, after the door 206 contacts the front end of the drying oven 1, the pressure plate 5 moves down. The pressure plate 5 pushes the door 206 down, and the door 206 drives the slider 2010 down. The slider 2010 pulls the spring 2011 to extend. When the door 206 contacts the support table 102, and the pressure plate 5 and the support table 102 press the door 206 tightly, the downward movement of the pressure plate 5 stops. At this time, the two doors 206 close the opening end of the drying oven 1, and the doors 206 are fixed on the drying oven 1. After drying is complete, the pressure plate 5 is moved upward, and the spring 2011 returns to its original state. The spring 2011 drives the slider 2010 to move upward, and the slider 2010 drives the door 206 to move upward. After the spring 2011 returns to its free state, the door 206 stops moving upward. The lower end of the door 206 is above the lower end of the caster wheel. At this time, the door 206 can be pulled directly to move the placement rack 201. Then, under the action of the spring 2011, the door 206 can move upward automatically.

[0051] In some embodiments of this application, a groove 7 is provided on the ground and adapted to the lifting platform 3. A bottom groove 8 is provided in the middle of the groove 7. A scissor lifting mechanism 9 is provided inside the bottom groove 8. The scissor lifting mechanism 9 is connected to the lifting platform 3 and drives the lifting platform 3 to move up and down.

[0052] In this embodiment, the scissor lift mechanism 9 is existing technology and will not be described in detail.

[0053] In use, after the lifting platform 3 is fully moved into the groove 7, the upper end of the lifting platform 3 is flush with the ground. The operator can then operate the scissor lift mechanism 9 to move the lifting platform 3 up and down.

[0054] In some embodiments of this application, the tray 204 is inserted into the placement rack 201.

[0055] Specifically, the placement rack 201 has a rectangular frame structure and multiple vertically distributed guide rails. Each guide rail is composed of two symmetrically distributed slots 202. Each slot 202 includes a U-shaped groove, one end of which is fixed with a limiting plate 203. After the material tray 204 is inserted into the slot 202, the material tray 204 contacts the inner wall of the slot 202.

[0056] In use, insert the tray 204 directly into the two slots 202 from the other end of the two U-shaped grooves. When the tray 204 contacts the limit, it is fully inserted into the slot 202, and then the tray 204 is mounted on the placement rack 201. To remove the tray 204, simply pull it out of the slot 202, making it easy to put or take the tray 204 off the placement rack 201.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
