Description

Technical Field

[0001] This utility model relates to a melt filter cartridge flipping device. Background Technology

[0002] Currently, the recycled polyester workshop has 10 production lines, each with 3 primary filters and 1 fine filter. Each filter is equipped with 2 sets of melt filter cartridges. Each set of melt filter cartridges includes a connecting plate and multiple cylindrical filter cartridges located on the same side of the connecting plate. After use, a large amount of molten material adheres to the surface of the filter cartridges, requiring them to be moved to a high-temperature hydrolysis furnace for cleaning to decompose the material. The current problem is:

[0003] After the melt filter cartridges come off the production line, they are manually rotated 180° before being sent into the hydrolysis furnace. This ensures the cylindrical filter cartridge opening faces downwards, facilitating the outflow of impurities. After exiting the hydrolysis furnace, the melt filter cartridges are manually rotated 180° again, this time with the cylindrical filter cartridge opening facing upwards. Because the filter screen of the cylindrical filter cartridges is soft, it is easily damaged during the rotation process. The entire set of melt filter cartridges is quite heavy, and rotating them is time-consuming and labor-intensive. 5-10 sets of melt filter cartridges need to be cleaned every day, resulting in a large workload, long operating time, and low efficiency.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] See Figures 1 to 8 The melt filter cartridge flipping device shown includes a support 1, a mounting mechanism 4, a drive mechanism 4, and a transfer mechanism, wherein:

[0034] The bracket 1 is used to support the installation mechanism, and a space is formed on the bracket 1 for the installation mechanism to rotate relative to the bracket 1.

[0035] The mounting mechanism includes a mounting frame 2 and a fixing member 3. The mounting frame 2 is used to place the melt filter element. The mounting frame 2 is rotatably mounted on the bracket 1 and the mounting frame 2 is detachably connected to the bracket 1. The fixing member 3 is used to fix the melt filter element on the mounting frame 2 to prevent the melt filter element from detaching from the mounting frame 2 as it rotates with the mounting frame 2.

[0036] The drive mechanism 4 is used to drive the mounting bracket 2 to rotate relative to the bracket 1 (rotation angle greater than 0° and less than or equal to 360°). The drive mechanism 4 includes a power unit and a drive unit. The power unit is connected to the drive unit, and the drive unit is fixedly connected to the mounting bracket 2 and the two are detachably connected.

[0037] The transfer mechanism is located above the support 1. The transfer mechanism is used to transfer the mounting mechanism to the support 1 and to transfer the rotated mounting frame 2 to the cleaning device. In some embodiments, the transfer mechanism can be an electric hoist.

[0038] In this example, after the mounting bracket 2 rotates 180° relative to the support 1, the opening of the cylindrical filter element of the melt filter element faces upward, which facilitates the transfer mechanism to move the rotated mounting mechanism to the cleaning device. There is no need to manually flip and transport it, saving time and effort. By moving the mounting mechanism instead of directly moving the melt filter element, the melt filter element will not be damaged.

[0039] In some embodiments, the mounting frame 2 includes a mounting platform 21, at least two support columns 22, and two couplings 23. The mounting platform 21 has a through hole 211 extending through its thickness direction to accommodate the melt filter element. A step is provided on the inner circumference of the through hole, and the connecting disc 6 of the melt filter element abuts against the step. The cylindrical filter element 7 extends out of the through hole and downward toward the support 1. The support columns 22 and the fixing member 3 are respectively provided on opposite sides of the mounting platform 21 in the thickness direction. The couplings 23 are connected to the support columns 22, and the axis of the two couplings 23 is the same straight line. The two couplings 23 are respectively used to rotate on opposite sides of the support 1. One end of one coupling 23 is detachably connected to the drive unit, and the other end of the coupling 23 is connected to the support column 22. The couplings 23 are provided to facilitate the rotation of the mounting mechanism relative to the support 1.

[0040] In this example, the fixing component 3 includes a fixing rod 31, a fastener 32, and a pressure plate 33. The fixing rod 31 is located on the side of the mounting platform 21 away from the support column 22. The upper end of the fixing rod 31 is provided with a threaded hole that mates with the fastener 32. The pressure plate 33 is connected to the fixing rod 31 through the fastener 32, and the pressure plate 33 can be rotatably connected to the fixing rod 31. The pressure plate 33 is used to press against the melt filter element. Before placing the melt filter element on the mounting frame 2, the pressure plate 33 is removed or rotated to a position that does not obstruct the through hole on the mounting platform 21. After the melt filter element is placed on the mounting frame 2, the pressure plate 33 is pressed against the connecting plate 6 of the melt filter element, and the fastener 32 is tightened so that the pressure plate 33 presses tightly against the connecting plate 6 of the melt filter element.

[0041] In some embodiments, multiple fasteners 3 are provided, and the multiple fasteners 3 are arranged around the outer periphery of the through hole on the mounting platform 21, which can better abut against the melt filter element and prevent the melt filter element from detaching from the mounting mechanism during the rotation process.

[0042] In some embodiments, the drive unit includes a sleeve 43, a locking bolt 45, and a connecting shaft 44. The sleeve 43 is a hollow cylindrical shape. One end of the sleeve 43 is sleeved on the drive shaft of the power unit, and the other end of the sleeve 43 is connected to one end of the connecting shaft 44. The sleeve 43 has an elongated opening that extends axially along the sleeve 43. The connecting shaft 44 has a mounting hole. The sleeve 43 is connected to the drive shaft by installing the locking bolt 45 in the opening and the mounting hole, so that the connecting shaft 44 can move axially along the sleeve 43. The other end of the connecting shaft 44 is used to connect to a coupling 23. Preferably, the sleeve 43 and the drive shaft of the power unit are concentrically arranged, and the sleeve 43 and the connecting shaft 44 are also preferably concentrically arranged.

[0043] The connection and disconnection of the connecting shaft 44 and the coupling 23 are achieved by operating the locking bolt 45 and the connecting shaft 44. Specifically, when connecting the connecting shaft 44 to the coupling 23, insert the other end of the connecting shaft 44 into the coupling 23 and then tighten the locking bolt 45. When separating the connecting shaft 44 from the coupling 23, loosen the locking bolt 45 and move the connecting shaft 44 towards the drive shaft closer to the power unit until the connecting shaft 44 disengages from the coupling 23, then tighten the locking bolt 45. When reconnecting the connecting shaft 44 to the coupling 23, loosen the locking bolt 45 and move the connecting shaft 44 away from the drive shaft away from the power unit until the other end of the connecting shaft 44 is inserted into the coupling 23, then tighten the locking bolt 45. When the drive mechanism 4 is working, the rotation of the drive unit drives the mounting mechanism to rotate.

[0044] In some embodiments, a groove is provided at the end of a coupling 23 away from the support column 22. The groove is recessed from one end of the coupling 23 in a direction away from the drive shaft of the power unit. When one end of the connecting shaft 44 extends into the groove of the coupling 23, the connecting shaft 44 is connected to the coupling 23. When one end of the connecting shaft 44 extends out of the groove of the coupling 23, the connecting shaft 44 is separated from the coupling 23. The device also includes two retaining rings 26, which are sleeved on the outside of the coupling 23. When the mounting bracket 2 is set on the support 1, the two retaining rings 26 are respectively set on opposite sides of the slot in the support plate 13. The retaining rings 26 can restrict the axial movement of the coupling 23 during rotation and prevent it from disengaging from the support, thereby improving the stability of the device.

[0045] In this example, the mounting platform 21 is disc-shaped, and multiple supports 22 are provided. These supports 22 are arranged circumferentially along the mounting platform 21. (See [reference]). Figure 1-4There are four support pillars 22, and the four support pillars 22 divide the mounting platform 21 into four equal parts, which can ensure the balance and stability of the mounting frame 2.

[0046] In some embodiments, the power unit includes a handwheel 41 and a reducer 42. The handwheel 41 is connected to the reducer 42. When the handwheel 41 is operated, the drive shaft of the reducer 42 rotates, which drives the sleeve 43, the connecting shaft 44, and the mounting bracket 2 to rotate.

[0047] In some embodiments, the mounting mechanism further includes a connecting ring 24, which is connected to the end of the support column 22 away from the mounting platform 21. The connecting ring 24 is opposite to the mounting platform 21. The connecting ring 24 is provided to ensure the stability of the mounting frame 2.

[0048] In some embodiments, a lifting lug 25 is provided on the side of the connecting ring 24 away from the support column 22. The lifting lug 25 is used to connect with the transfer mechanism. The lifting lug 25 is provided so that the transfer mechanism can hook the lifting lug 25 to move the installation mechanism to the cleaning device.

[0049] In this example, the bracket 1 includes a base frame 11 and two opposing side frames 12. Both side frames 12 are located on the same side of the base frame 11, and a space is formed between the base frame 11 and the two side frames 12 for the mounting bracket 2 to rotate relative to the bracket 1. The base frame 11 includes two first transverse members and two longitudinal members. The first transverse members and the longitudinal members are perpendicular to each other, and the two first transverse members and the two longitudinal members are connected to form a hollow quadrilateral structure. The side frames 12 include second transverse members and two vertical members. The first transverse members and the second transverse members are arranged parallel to each other, and the first transverse members, the second transverse members and the two vertical members are connected to form a hollow quadrilateral structure. The first transverse members are along the X-axis, the longitudinal members are along the Y-axis, and the vertical members are along the Z-axis. A support plate 13 is provided on the side of the two side frames 12 away from the base frame 11. The support plate 13 has a groove that is recessed towards the base frame 11, and the opening of the groove faces upward. The coupling 23 is rotatably disposed in the groove of the support plate 13.

[0050] In some embodiments, the device further includes a support 5 connected to the side of one side frame 12 away from the other side frame 12, and the drive mechanism 4 is connected to the support 5. The support 5 is provided to support and fix the drive mechanism 4.

[0051] The specific implementation method of the melt filter cartridge flipping device in this example is as follows:

[0052] First, the installation mechanism is hoisted to the ground by the transfer mechanism. The melt filter element is placed on the mounting frame and fixed with fasteners. Then, the mounting frame is moved to the support by the transfer mechanism. Next, the drive unit is fixedly connected to the mounting frame, and the transfer mechanism is removed. Driven by the power unit, the drive unit rotates, causing the installation mechanism to rotate 180° so that the filter element opening faces upward. Then, the transfer mechanism suspends the rotated mounting frame, and the locking bolts and connecting shaft are operated to separate the mounting frame from the drive unit. Finally, the transfer mechanism moves the installation mechanism to the cleaning device.

[0053] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model.
