Description

Technical Field

[0001] The invention relates to the technical field of seawater desalination and water treatment, and relates to a large-scale seawater reverse osmosis pretreatment multi-media pressure filter filling filling tool. Background Art

[0002] The filling of traditional multi-media pressure filters relies on manual operation, which has problems such as low efficiency, uneven distribution of fillers, the rapid fall of fillers from high altitudes that easily damages the water cap inside the filter, and safety hazards caused by large dust in a closed environment. Especially in large projects, there are many multi-media pressure filter devices and large tanks, and a large amount of fillers need to be filled. Efficient and safe filling tools are urgently needed to improve the overall efficiency of the project.

[0003] In the past projects, although the funnel-shaped filling bin was used to fill the fillers in the large filters, most of them required supporting wooden boards to be arranged inside the filter to ensure that the water cap at the bottom of the filter would not be damaged during the falling process of the fillers. At the same time, most of the fillers gathered at the bottom of the filling manhole, and more manpower was needed to transfer the fillers inside and spread them to the bottom of the filter. A large amount of dust was generated during the falling process of the fillers, which posed a great safety hazard.

[0004] The above loading method not only wastes more time to arrange the wooden boards to protect the water cap, but also needs to remove the wooden boards afterwards, which seriously affects the loading efficiency. There is also a risk of damaging the bottom water cap during the loading process. At the same time, it requires high labor costs, low efficiency, and it is difficult to ensure safety and stability. Summary of the invention

[0005] In view of the above technical problems, the present invention provides a large-scale seawater reverse osmosis pretreatment multi-media pressure filter filling tool, which improves the efficiency and safety of filling, reduces the labor cost of filling, and ensures the operational stability of the filling process.

[0007] Furthermore, the filler loading bin comprises an upper bin body in the shape of an inverted truncated cone and a cylindrical bottom pipe; the bottom pipe is fixedly arranged on the bottom surface of the upper bin body, and the bottom pipe is connected to the interior of the upper bin body; The outer surface of the bottom pipe is provided with a plurality of grooves, and the bottom pipe is connected with the upper part of the filler conveying pipe through the grooves and the clamp.

[0008] Furthermore, a circular fixing steel plate is fixedly arranged on the bottom surface of the upper warehouse body, and the fixing steel plate is arranged around the bottom pipe.

[0009] Furthermore, a ring-shaped rubber buffer pad is arranged on the periphery of the fixed steel plate, and the outer ring diameter of the rubber buffer pad is larger than the bottom surface diameter of the upper warehouse body.

[0010] Furthermore, a plurality of upper fixing ears are fixedly arranged on the bottom of the fixing steel plate; and the plurality of upper fixing ears are evenly arranged around the four sides of the bottom pipe.

[0011] Furthermore, a plurality of lower fixing ears are arranged at the lower part of the sleeve of the filler distribution plate.

[0012] Furthermore, the number of the upper fixing lugs and the number of the lower fixing lugs are the same, and each upper fixing lug and a lower fixing lug are connected by a steel wire rope.

Specifically, the length of the packing delivery 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.

[0026] In this embodiment, the filler loading bin 1 comprises an upper bin body 1-1 in the shape of an inverted truncated cone and a cylindrical bottom pipe 1-2; the bottom pipe 1-2 is fixedly arranged on the bottom surface of the upper bin body 1-1, and the bottom pipe 1-2 is connected to the interior of the upper bin body 1-1; preferably, the bottom pipe 1-2 and the upper bin body 1-1 are connected by welding; wherein the upper bin body in the shape of an inverted truncated cone facilitates the introduction and concentration of fillers; The outer surface of the bottom pipe 1-2 is provided with a plurality of grooves, and the bottom pipe 1-2 is connected to the upper part of the filler delivery pipe 2 through the grooves and the clamp.
