Description

Technical Field

[0001] This utility model relates to the field of seawater desalination and water treatment technology, and relates to a packing tool for a large-scale seawater reverse osmosis pretreatment multi-media pressure filter. Background Technology

[0002] Traditional multi-media pressure filters rely on manual filling, which suffers from low efficiency, uneven packing distribution, damage to the internal water caps from rapid packing descent from heights, and safety hazards due to high dust levels in confined environments. Especially in large-scale projects, where there are numerous multi-media pressure filter units and large tanks requiring a large amount of packing material, efficient and safe filling tools are urgently needed to improve overall project efficiency.

[0003] In the past, the filling process of large filter packing in projects also used funnel-shaped packing bins to fill the packing. However, most of the packing required supporting wooden boards to be placed inside the filter to ensure that the packing would not damage the bottom water cap of the filter during the filling process. At the same time, most of the packing accumulated at the bottom of the filling manhole, requiring more manual labor to transfer the packing inside and spread it to the bottom of the filter. The packing also generated a lot of dust during the falling process, which posed a great safety hazard.

[0004] The above filling method not only wastes more time to set up the protective wooden boards for the water cap, but also requires the removal of the boards afterward, which seriously affects the filling efficiency. It also poses a risk of damaging the bottom water cap during the filling process. In addition, it requires high labor costs, is inefficient, and makes it difficult to guarantee safety and stability.

[0032] This utility model provides an embodiment of a large-scale seawater reverse osmosis pretreatment multi-media pressure filter packing tool, such as... Figures 1-3 As shown, the packing filling tool includes: a funnel-shaped packing filling chamber 1, a packing delivery pipe 2 connected to the bottom of the packing filling chamber 1, and a packing distribution plate 3 connected to the bottom of the packing delivery pipe 2; in use, the packing filling chamber 1 is installed at the manhole of the multi-media pressure filter; the packing delivery pipe 2 and the packing distribution plate 3 are installed inside the multi-media pressure filter.

[0033] The packing distribution plate 3 includes a sleeve 3-1 for connecting with the packing delivery pipe 2, several reinforcing ribs 3-2, and a packing buffer steel plate 3-3; the reinforcing ribs 3-2 are long strip steel bars (preferably 10mm threaded steel bars), and the two ends of the several reinforcing ribs 3-2 are respectively connected to the sleeve 3-1 and the packing buffer steel plate 3-3 by welding.

[0034] One end of each reinforcing rib 3-2 is fixedly connected to the bottom of the sleeve 3-1, and the other end is fixedly connected to the edge of the packing buffer steel plate 3-3. The packing buffer steel plate 3-3 is located below the outlet of the packing conveying pipe 2 and is used to buffer materials to protect the water cap inside the multi-media pressure filter. Specifically, the length of the packing conveying pipe 2 is controlled so that the packing buffer steel plate 3-3 is located above the water cap inside the multi-media pressure filter to avoid contact between the packing buffer steel plate 3-3 and the water cap.

[0035] In this embodiment, the filling chamber 1 includes an upper chamber 1-1 in the shape of an inverted frustum and a bottom pipe 1-2 in the shape of a cylinder; the bottom pipe 1-2 is fixedly disposed on the bottom surface of the upper chamber 1-1, and the bottom pipe 1-2 and the upper chamber 1-1 are internally connected; preferably, the bottom pipe 1-2 and the upper chamber 1-1 are connected by welding; wherein, the upper chamber in the shape of an inverted frustum facilitates the introduction and concentration of filling material;

[0036] The outer surface of the bottom pipe 1-2 is provided with several grooves, and the bottom pipe 1-2 is connected to the upper part of the packing conveying pipe 2 through the grooves and clamps. Preferably, the outer surface of the bottom pipe 1-2 is provided with at least two grooves, and the grooves and clamps work together to ensure a stable connection between the bottom pipe 1-2 and the packing conveying pipe 2.

[0037] In this embodiment, an annular fixing steel plate 7 is fixedly installed on the bottom surface of the upper hopper 1-1, and the fixing steel plate 7 is arranged around the bottom pipe 1-2.

[0038] In this embodiment, an annular rubber buffer pad 4 is provided around the fixed steel plate 7, and the outer ring diameter of the rubber buffer pad 4 is larger than the bottom diameter of the upper compartment 1-1, so as to cover the entire bottom surface of the upper compartment 1-1.

[0039] In this embodiment, a plurality of upper fixing lugs 6 are fixedly provided at the bottom of the fixed steel plate 7; and the plurality of upper fixing lugs 6 are evenly arranged around the bottom pipe 1-2.

[0040] Preferably, the number of upper fixed lifting lugs 6 is greater than or equal to 3; the upper fixed lifting lugs 6 are fixed to the bottom of the fixed steel plate 7 by welding; preferably, the distance between the upper fixed lifting lugs 6 and the bottom pipe does not exceed 5 cm.

[0042] The bottom diameter of the upper compartment 1-1 is larger than the diameter of the manhole, which ensures that the upper compartment is located outside the manhole. The area of ​​the rubber buffer pad can cover the entire bottom surface of the upper compartment 1-1, which can prevent the bottom of the upper compartment from contacting the manhole and causing wear to the manhole during use.

[0043] The fixing steel plate is inserted into the manhole for positioning during use. By controlling the reasonable difference between the diameter of the fixing steel plate and the diameter of the manhole, it can be ensured that the relative position of the entire filling chamber and the manhole is fixed during filling. This prevents problems such as movement of the upper chamber caused by uneven weight distribution of materials in the filling chamber, thus enhancing the stability of the filling chamber 1.

[0044] In this embodiment, the packing conveying pipe 2 and the packing distribution plate 3 are inserted through the manhole and need to be smaller than the manhole size.

Each upper fixed lifting lug 6 and each lower fixed lifting lug 3-4 are connected by a steel wire rope 5, which connects the packing distribution plate 3 and the packing filling chamber 1. Specifically, the steel wire rope can be a conventional type with a diameter of 2-5mm.

[0047] Preferably, cable ties are used to fix the steel wire rope connecting the lifting lugs 6 and 3-4 to the surface of the packing conveying pipe 2, preventing the steel wire rope from scraping against the filter water distribution pipe or rubber lining when the pipe moves during the packing filling process. Furthermore, in this invention, the packing distribution disc 3 is fixed to the packing conveying pipe 2 by clamps and simultaneously fixed to the bottom of the packing filling chamber 1 by steel wire ropes, ensuring the stability and accuracy of the distribution disc during the filling process.

[0048] In this embodiment, the outer surface of the sleeve 3-1 is provided with several grooves, and the sleeve 3-1 is connected to the lower part of the packing conveying pipe 2 through the grooves and clamps.

[0049] In this embodiment, the packing conveying pipe 2 is a flexible hose lined with steel wire. The flexible hose lined with steel wire can enhance the strength and wear resistance of the pipe, while ensuring the smooth conveying of the packing. The use of a flexible hose also makes it easy to manually move the packing conveying pipe during the filling process to change the falling position of the packing, thus ensuring the uniform distribution of the packing in the filter. The two ends of the hose are provided with clamp connection structures to facilitate connection with the packing filling chamber 1 and the packing distribution plate 3.

[0050] The utility model provides a special tool for filling multi-media pressure filter media, which is suitable for rapid layered filling of filter media such as quartz sand and activated carbon, and is compatible with filter tanks with a diameter ≥3m.
