Description

Technical Field

[0001] The invention relates to a measuring instrument storage device, in particular to a trinity rotating tower capable of storing a filter membrane, a filter cartridge and a low-concentration sampling head at the same time. Background Art

[0002] In the atmospheric environment PM2.5 and PM10 weighing tests, the main components for collecting atmospheric particulate matter include filter membranes, filter cartridges, low-concentration sampling heads, etc. These components need to be stored in a constant temperature and humidity cabin. Because the space in the constant temperature and humidity cabin is small, storing the filter membranes, filter cartridges, and low-concentration sampling heads at the same time usually requires more than three types of tray racks to store the filter membranes, filter cartridges, and low-concentration sampling heads respectively. Due to the large number, they take up space and are inconvenient to take and put. In addition, each component must be numbered, recorded, and stored and retrieved, which is a large workload and prone to errors. Summary of the invention

[0003] In view of the shortcomings of the prior art in that the storage of filter membranes, filter cartridges and low-concentration sampling heads takes up space, is inconvenient, requires a lot of work, and is prone to errors, the problem to be solved by the present invention is to provide a three-in-one rotating tower for storing an atmospheric particulate matter measuring device that can simultaneously store filter membranes, filter cartridges and low-concentration sampling heads.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The invention provides a trinity rotating tower for storing an atmospheric particle measuring device, comprising a vertical shaft which is mounted on a base, a plurality of discs being mounted on the vertical shaft in layers for coaxial rotation, and a handle being arranged on the top of the vertical shaft.

[0006] The first layer of discs is fixed with the first sleeve by screws and installed on the upper end of the vertical shaft; the third sleeve and the second layer of discs are fixed with screws on the upper part of the vertical shaft and the bottom of the first sleeve, and the other layers are installed according to the above structure.

[0007] The invention also has a second shaft sleeve for increasing the height between adjacent discs, which is sleeved on the vertical shaft and between the upper installation shaft sleeve and the lower installation shaft sleeve.

[0008] The disc is a steel plate, and a plurality of storage stations with the same structure are evenly distributed in the circumferential direction. Each storage station is arranged radially, and oblong holes and special-shaped notches are arranged in sequence from the center to the circumferential direction.

[0009] Large arc scale lines are arranged on both sides of the oblong hole, and small arc scale lines are arranged on both sides of the special-shaped notch, both of which are filter membrane storage positions.

[0010] The irregular notch is generally a rectangular shape arranged along the radial direction, which serves as the filter cartridge placement position; the two long sides are symmetrically provided with angular notches, which together with the oblong hole form a sampling head storage position;

[0011] Work station numbers are provided on the edge of the disc and between adjacent special-shaped notches.

[0012] The present invention has the following beneficial effects and advantages:

[0013] 1. The present invention is used to store filter membranes, filter cartridges and low-concentration sampling heads. Compared with the past, the storage method saves space and is relatively stable. The same volume of compartments can store a large number of items, which are easy to take and put. The workstations are numbered and recorded by workstation numbers, which is easy to operate and reduces the error rate.

[0014] 2. The present invention is used to store filter membranes, filter cartridges and low-concentration sampling heads, and the weighing process can be operated manually or automatically. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, the present invention provides a three-in-one rotating tower for storing an atmospheric particulate matter measuring device, comprising a vertical shaft 7 mounted on a base 6, a plurality of disks 5 being mounted on the vertical shaft 7 for coaxial rotation in layers, and a handle 1 being provided at the top of the vertical shaft 7.

[0021] The first layer of discs is fixed with the first sleeve 2 by screws and installed on the upper end of the vertical shaft 7; the third sleeve 4 and the second layer of discs are fixed with screws on the vertical shaft 7 and the bottom of the first sleeve 2, and the other layers are installed according to the above structure.

[0022] A second sleeve 3 is also provided for increasing the height between adjacent discs and is sleeved on the vertical shaft 7 and between the upper mounting sleeve and the lower mounting sleeve.

[0023] For example, the disc 5 installed on the top layer is fixed to the first sleeve 2 with screws, and the second sleeve 3 is mounted on the vertical shaft 7 and the bottom of the first sleeve 2 to increase the height between two adjacent layers of discs. Therefore, the interlayer height can be adjusted and determined according to the second sleeve 3 for storing weighing objects. The third sleeve 4 and the next layer of discs are fixed with screws and mounted on the vertical shaft 7; the next layer determines whether to install the second sleeve 3 according to the interlayer distance requirements.

[0024] like Figure 2 As shown, the disk 5 is a steel plate, and a plurality of storage stations with the same structure are evenly distributed in the circumferential direction. Each storage station is arranged radially, and is provided with an oblong hole 11 and a special-shaped notch 12 in sequence from the center to the circumferential direction.

[0025] Large arc scale lines 9 are arranged on both sides of the oblong hole, and small arc scale lines 10 are arranged on both sides of the special-shaped notch, which are all filter membrane storage positions 503. Among them, the large arc scale lines 9 are used as 90mm filter membrane storage positions, and the small arc scale lines 10 are used as 47mm filter membrane storage positions.

[0026] The irregular notches are generally arranged in a radially rectangular shape, serving as a filter cartridge storage position 502; the two long sides are symmetrically provided with angular notches and arc notches for easy access; the two angular notches and the oblong hole form a sampling head storage position 501; the low-concentration sampling head 13 in the storage state is as shown Figure 3 shown.

[0027] In this embodiment, the disk 5 has 8 layers, all of which are made of 1.5 mm thick stainless steel plates. Each layer has the same structure. There are 12 storage stations along the circumference, and each station is arranged radially. The oblong holes 11 and the special-shaped notches 12 are hollow structures. The large arc scale lines 9 and the small arc scale lines 10 are used to distinguish the storage areas of filter membranes of different specifications. Each station can select a filter membrane, a filter cartridge or a low-concentration sampling head 13 to store. The shapes are consistent and can be stably positioned. The station number can also be recorded by the station number set on the edge of the disk 5 and between adjacent special-shaped notches.

[0028] When in use, the vertical shaft 7 is installed on the base 6, and the assembled shaft sleeve and disc assembly are sleeved on the vertical shaft to rotate the disc 5, which is convenient for taking and placing operations.

[0029] The present invention is used to store filter membranes, filter cartridges and low-concentration sampling heads. Compared with the past, the storage method saves space and is relatively stable. A large number of containers of the same volume can be stored, and the containers are easy to take and put. The containers are numbered and recorded through work station labels, which is easy to operate and also reduces the error rate.
