Description

Technical Field

[0001] The present invention relates to a central feeding system, which is an improvement on the printing and dyeing process technology and equipment for chemical material melting and mixing and distribution, and belongs to the field of printing and dyeing automation technology. Background Art

[0002] In a central feeding system with the Chinese patent authorization publication number CN107653607B and the patent name "A Central Feeding System", the central feeding system includes a chemical material tank, an internal circulation system, a chemical material tank water washing system and a distribution system. The internal circulation system is used to re-inject the dye liquor in the chemical material tank into the chemical material tank after circulation. The chemical material tank water washing system is used to clean the tank wall and the tank cover of the chemical material tank. The distribution system is used to distribute and transport the fuel in the chemical material tank to each dyeing machine. Among them, the internal circulation system includes a jet device arranged near the bottom of the chemical material tank. Although this jet device can provide an internal circulation vortex and entrainment effect to break the dynamic balance in the tank, the generated internal circulation vortex is weak and fails to better promote the melting and mixing of dye chemicals. Therefore, the existing one needs to be further improved. Summary of the Invention

Detailed implementation manners

[0007] The central feeding system includes a chemical melting tank, an internal circulation system, a chemical melting tank water washing system, and a distribution system. The internal circulation system is used to re-inject the dye liquor in the chemical melting tank into the chemical melting tank after circulation. The chemical melting tank water washing system is used to clean the tank wall and the tank cover of the chemical melting tank. The distribution system is used to distribute and transport the dyes in the chemical melting tank to each dyeing machine; The internal circulation system includes a jet device 100, a low overflow device, and an internal circulation pump connected through a connecting pipe. The dye liquor enters the internal circulation pump through the low overflow device in the chemical melting tank, and then re-enters the chemical melting tank through the jet device 100.

[0008] The basic structure and operation mode of this central feeding system are similar to those introduced in the Chinese patent authorization announcement number CN107653607B, and the patent name is a central feeding system. In this embodiment, the structure and operation mode of the jet device 100 are mainly introduced.

[0009] As shown in the appendix Figure 1 As shown, there are several jet devices 100, which are arranged near the bottom of the chemical melting tank and are spaced circumferentially around the central axis of the chemical melting tank as the rotation axis.

[0010] As shown in the appendix Figure 2 To appendix Figure 4 As shown, the jet device 100 includes a main body 1, a cover body 2, and a rotating body 3.

[0011] The main body 1 is cup-shaped, and its side wall is provided with a liquid inlet 11 and a first liquid outlet 12 for connecting the connecting pipe. The cover body 2 is covered in the opening of the main body 1 in a conventional manner and has several second liquid outlets 21. The rotating body 3 can be rotatably installed in the main body 1 with the central axis of the main body 1 as the rotation axis, and several blades 31 are arranged around its periphery. The central axis of the liquid inlet 11 of the main body 1 is offset from the radial direction of the rotating body 3.

[0012] There are two liquid inlets 11 and two first liquid outlets 12 of the main body 1 respectively.

[0013] The liquid inlets 11 are evenly spaced around the central axis of the main body 1 . Because the central axis of the liquid inlet 11 of the main body 1 deviates from the radial direction of the rotating body 3 , the central axes of the two liquid inlets 11 are parallel but staggered.

[0014] The first liquid outlets 12 are arranged at equal intervals around the central axis of the main body 1. The first liquid outlets 12 can also be arranged like the liquid inlet 11, with the central axis of the first liquid outlet 12 deviating from the radial direction of the rotating body 3, and the central axes of the two first liquid outlets 12 are parallel but staggered.

[0015] In order to better spray the dye liquid onto the blades 31 to promote the rotation of the rotating body 3 , the liquid inlet 11 of the main body 1 is plugged with a liquid inlet pipe 32 , and the liquid inlet pipe 32 extends into the inner cavity of the main body 1 .

[0016] The bottom of the main body 1 and the side of the cover body 2 facing the inner cavity of the main body 1 are convexly provided with a rotating shaft 33 seat, and the rotating shaft 33 seat is axially provided with a rotating hole; the upper and lower ends of the rotating body 3 each have a rotating shaft 33 extending outward from the middle axis, and the two rotating shafts 33 are respectively inserted into the rotating holes of the main body 1 and the cover body 2. The end of the rotating shaft 33 of the rotating body 3 is formed into a cone shape and is point-contacted and connected with the bottom of the corresponding rotating hole. Therefore, the contact area between the rotating shaft 33 of the rotating body 3 and the bottom of the rotating hole is smaller, and the friction is smaller. When the dye liquid is sprayed onto the blade 31, the rotating body 3 is easier to rotate.

[0017] The dye liquid is sprayed onto the blade 31 through the liquid inlet pipe 32 to promote the rotation. Driven by the blade 31, the dye liquid can flow out from the first liquid outlet 12 on the side of the main body 1 and the second liquid outlet 21 on the top of the main body 1. The jet device 100 can disturb the dye liquid in the material tank, effectively improve the efficiency of material melting and mixing, reduce the total melting and mixing time and improve the melting and mixing effect.

[0018] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention are all equivalent replacement modes and are included in the protection scope of the present invention.
