Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum box technology, and in particular to an adjustable lifting device for a vacuum box. Background Technology
[0002] A vacuum box is a negative pressure device that comes into contact with the filter cloth in a vacuum filter and creates a vacuum. When the vacuum box sucks up the wastewater from the surface of the filter cloth, it flows through the vacuum chamber inside the vacuum box. As the working time and storage time increase, scale and deposits will appear on the surface of the vacuum chamber, requiring regular cleaning of its interior.
[0003] Existing tubular vacuum boxes are generally fixed to the mounting frame of the filter press. The only way to facilitate cleaning is by designing the connectors and external viewing channels of the vacuum box to be detachable. However, this operation is complicated, time-consuming and labor-intensive, and the cleaning efficiency is low when the vacuum box is near the horizontal outlet. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable lifting device for vacuum boxes. This device uses a linkage mechanism in conjunction with a transmission mechanism to achieve rapid and stable lifting and tilting of the vacuum box, thus solving the problems of complex operation, time-consuming and labor-intensive operation, and low cleaning efficiency of existing vacuum box technologies.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A vacuum box lifting and adjusting device includes: a fixed base fixedly connected to a mounting frame, a transmission mechanism fixedly connected to one end of the fixed base, and a linkage mechanism disposed at the output end of the transmission mechanism for lifting the vacuum box. One end of the linkage mechanism is rotatably connected to the mounting frame, a vacuum box is disposed in the middle of the mounting frame, and the bottom end of the vacuum box is fixedly connected to the linkage mechanism.
[0007] Preferably, the transmission mechanism includes: a worm gear fixedly connected to one side of the fixed seat, a worm connected to the worm gear and passing through the fixed seat, and a handle disposed on one side of the worm gear, wherein one end of the worm gear is provided with the linkage mechanism.
[0008] Preferably, the linkage mechanism includes: a first link rotatably connected to the end of the worm gear and a second link rotatably connected to the first link.
[0009] Preferably, the second link includes: a connecting section rotatably connected to the end of the first link, a receiving section perpendicular to the connecting section for mounting the vacuum box, and an extension section vertically disposed above the receiving section and rotatably connected to the mounting bracket.
[0010] Preferably, the vacuum box is disposed inside the opening of the mounting bracket.
[0011] Preferably, the linkage mechanism is provided inside the opening, and the extension section is provided at one end of the opening.
[0012] Preferably, a limiting seat is provided at the other end of the opening, and the limiting seat is located directly above the receiving section.
[0013] Preferably, the length of the receiving section is adapted to the length of the opening.
[0014] Preferably, a mounting base for receiving the vacuum box is provided above the receiving section.
[0015] Preferably, the worm gear is horizontally positioned.
[0016] The beneficial effects of this utility model are as follows:
[0017] (1) This utility model uses worm gear transmission. Since the size of the worm gear and worm is small, it can adapt to limited space and installation position, making the structure of the device very compact and easy to disassemble and assemble. Moreover, due to the meshing effect between the worm gear and worm, the motion of the worm gear transmission is relatively smooth, which can effectively reduce impact and vibration, thereby extending its service life.
[0018] (2) This utility model drives the vacuum box to rise and fall through the linkage mechanism. Because the linkage mechanism saves effort, has low cost, and has a compact structure, occupies little space, and has good stability.
[0019] (3) This utility model limits the rotation angle of the linkage mechanism by limiting the limit seat, avoiding problems such as the vacuum box overturning and the vacuum box not being properly sealed inside, thus ensuring the stability of the vacuum box during operation.
[0020] In summary, this utility model has the advantages of good stability, long service life, simple structure and convenient assembly and disassembly. Attached Figure Description

[0028] Example
[0029] like Figure 1-4 As shown, this embodiment provides a vacuum box lifting adjustable device, including: a fixed base fixedly connected to a mounting frame, a transmission mechanism fixedly connected to one end of the fixed base, and a linkage mechanism 5 disposed at the output end of the transmission mechanism 3 for lifting the vacuum box 4. One end of the linkage mechanism 5 is rotatably connected to the mounting frame 1, the vacuum box 4 is disposed in the middle of the mounting frame 1, and the bottom end of the vacuum box 4 is fixedly connected to the linkage mechanism 5.
[0030] The transmission mechanism 3 includes: a worm gear 31 fixedly connected to one side of the fixed base 2, a worm 32 connected to the worm gear 31 and passing through the fixed base 2, and a handle 33 disposed on one side of the worm gear 31. One end of the worm 32 is provided with the linkage mechanism 5. The worm gear 31 can be manually rotated through the handle 33 to precisely control the rotation angle of the linkage mechanism 5, so that the inside of the vacuum box 4 can be quickly cleaned, thereby ensuring the cleanliness of the inside of the vacuum box 4.
[0031] Meanwhile, the worm gear 31 and the worm 32 are relatively small in size, which can adapt to limited space and installation position. Furthermore, due to the meshing action between the worm gear 31 and the worm 32, the worm gear transmission has good motion smoothness and can effectively reduce impact and vibration.
[0032] In this embodiment, the linkage mechanism 5 includes a first link 51 rotatably connected to the end of the worm gear 32 and a second link 52 rotatably connected to the first link 51. The linkage mechanism 5 is labor-saving, low-cost, compact in structure, occupies little space, and has good stability.
[0033] In this embodiment, the second connecting rod 52 includes: a connecting section 521 rotatably connected to the end of the first connecting rod 51, a receiving section 522 perpendicularly disposed to the connecting section 521 for mounting the vacuum box 4, and an extension section 523 vertically disposed above the receiving section 522 and rotatably connected to the mounting bracket 1, wherein the receiving section 522 is used to support the vacuum box 4.
[0034] In this embodiment, the vacuum box 4 is provided in the opening 11 of the mounting bracket 1, the linkage mechanism 5 is provided in the opening 11, and the extension section 523 is provided at one end of the opening 11, so as to ensure the compactness of the overall structure and save space.
[0035] In this embodiment, a limiting seat 12 is provided at the other end of the opening 11. The limiting seat 12 is located directly above the receiving section 522 and is fixedly connected to the mounting bracket 1. That is, the limiting seat 12 is located on the opposite side of the extension section 523. The space between the two is used to install the vacuum box 4. The limiting seat 12 is used to limit the rotation angle of the linkage mechanism 5 to avoid the vacuum box 4 from tipping over and causing problems such as poor sealing inside the vacuum box 4.
[0036] In this embodiment, the length of the receiving section 522 is adapted to the length of the opening 11. Preferably, the length of the receiving section 522 is greater than the length of the opening 11, so as to ensure that the end of the receiving section 522 has enough length to be blocked by the limiting seat 12, and to prevent the linkage mechanism 5 from overturning and making it inconvenient to clean the vacuum box 4.
[0037] Of course, a mounting base 524 for receiving the vacuum box 4 is provided above the receiving section 522. The shape of the top of the mounting base 524 is adapted to the shape of the vacuum box 4 to ensure that the vacuum box 4 can remain stable during lifting (i.e., when tilting) and will not easily shake.
[0038] In addition, the horizontal arrangement of the worm gear 32 makes the structure of both the worm wheel 31 and the worm gear 32 more compact, lightweight, and ingeniously shaped, facilitating installation and maintenance.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
