Description

Technical Field

[0001] This utility model relates to a central feeding system, which is an improvement on the dyeing and printing process technology and equipment in terms of chemical mixing and distribution, and belongs to the field of dyeing and printing automation technology. Background Technology

[0002] The Chinese patent publication number CN107653607B, entitled "A Central Injection System," describes a central injection system comprising a dyeing cylinder, an internal circulation system, a dyeing cylinder washing system, and a distribution system. The internal circulation system recirculates the dye solution within the dyeing cylinder and re-injects it. The dyeing cylinder washing system cleans the cylinder walls and cover. The distribution system distributes the fuel from the dyeing cylinder to various dyeing machines. The internal circulation system includes a jetting device located near the bottom of the dyeing cylinder. While this jetting device provides internal circulation vortices and suction to break the dynamic balance within the cylinder, the generated internal circulation vortices are weak and fail to effectively promote dye-chemical mixing. Therefore, the existing system requires further improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a central injection system that can better promote the mixing of dyes and chemicals.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The central feeding system includes a dyeing cylinder, an internal circulation system, a dyeing cylinder washing system, and a delivery system. The internal circulation system includes a spray device, a low overflow device, and an internal circulation pump connected by connecting pipes. The dye liquor enters the internal circulation pump through the low overflow device in the dyeing cylinder, and then re-enters the dyeing cylinder through the spray device. There are several spray devices, which are arranged near the bottom of the dyeing cylinder and are circumferentially spaced around the central axis of the dyeing cylinder. The spray device includes a main body, a cover, and a rotating body. The main body is cup-shaped and its side wall has an inlet and a first outlet connected to the connecting pipe. The cover is placed in the opening of the main body and has several second outlets. The rotating body is rotatably installed inside the main body and has several blades around its periphery. The central axis of the inlet of the main body is offset from the radial direction of the rotating body.

[0006] The advantage of this invention is that it can better promote the mixing of dyes and chemicals. Attached Figure Description

[0011] Figure 5 This is a cross-sectional view of the jet device in an embodiment of the present invention (the cross-section passes through the central axis of the main body). Detailed Implementation

[0012] The central feeding system includes a dyeing cylinder, an internal circulation system, a dyeing cylinder washing system, and a distribution system. The internal circulation system is used to re-inject the dye solution in the dyeing cylinder after circulation. The dyeing cylinder washing system is used to clean the cylinder wall and cylinder cover. The distribution system is used to distribute and transport the dye in the dyeing cylinder to each dyeing machine.

[0013] The internal circulation system includes a spray device 100, a low overflow device, and an internal circulation pump connected by a connecting pipe. The dye liquor enters the internal circulation pump through the low overflow device in the dyeing tank, and then re-enters the dyeing tank through the spray device 100.

[0014] The basic structure and operation of this central injection system are similar to those described in Chinese Patent Publication No. CN107653607B, entitled "A Central Injection System". In this embodiment, the structure and operation of the jetting device 100 are described in detail.

[0015] As attached Figure 1 As shown, there are several jetting devices 100 that are arranged near the bottom of the chemical cylinder and at intervals around the central axis of the chemical cylinder.

[0016] As attached Figure 2 To be continued Figure 4 As shown, the jetting device 100 includes a main body 1, a cover 2, and a rotating body 3.

[0017] The main body 1 is cup-shaped and has an inlet 11 and a first outlet 12 connected to the connecting pipe on its side wall. The cover 2 is conventionally placed over the opening of the main body 1 and has several second outlets 21. The rotating body 3 is rotatably installed inside the main body 1 with the central axis of the main body 1 as the axis of rotation and has several blades 31 around its periphery. The central axis of the inlet 11 of the main body 1 is offset from the radial direction of the rotating body 3.

[0018] The main body 1 has two inlet ports 11 and two first outlet ports 12.

[0019] The liquid inlets 11 are evenly distributed around the central axis of the main body 1. Since the central axis of the liquid inlets 11 of the main body 1 is offset from the radial direction of the rotating body 3, the central axes of the two liquid inlets 11 are parallel but staggered.

[0020] The first liquid outlet 12 is evenly distributed around the central axis of the main body 1. The first liquid outlet 12 can also be arranged like the liquid inlet 11, with the central axis of the first liquid outlet 12 offset from the radial direction of the rotating body 3, and the central axes of the two first liquid outlets 12 are parallel but staggered from each other.

[0021] In order to better spray the dye solution onto the blade 31 to drive the rotation of the rotating body 3, the liquid inlet 11 of the main body 1 is connected to the liquid inlet pipe 32, which extends into the inner cavity of the main body 1.

[0022] The bottom of the main body 1 and the side of the cover 2 facing the inner cavity of the main body 1 are 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 2. The end of the rotating shaft 33 of the rotating body 3 is formed into a conical shape and makes point contact 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 small, the friction is less, and the rotating body 3 rotates more easily when the dye is sprayed onto the blade 31.

[0023] The dye liquor is sprayed through the inlet pipe 32 onto the blade 31 to drive its rotation. Driven by the blade 31, the dye liquor can flow out from the first outlet 12 on the side of the main body 1 and the second outlet 21 on the top of the main body 1. The spray device 100 can agitate the dye liquor in the chemical mixing tank, effectively improving the efficiency of chemical mixing, reducing the total mixing time and improving the mixing effect.

[0024] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
