[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0031] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0032] Reference Figure 1-5 A pump-type feeding device for a concentrated preparation tank according to this embodiment is described.

[0033] The prior art includes a concentrated preparation tank 5 and a first delivery pipe 6 connected to the concentrated preparation tank 5 , and a delivery pump 9 is arranged on the first delivery pipe 6 .

[0034] What is different from the prior art is that Figure 1 As shown, this embodiment also includes an auxiliary material tank group, in which auxiliary liquid is contained, and the liquid outlet end of the auxiliary material tank group and the liquid inlet end of the first delivery pipe 6 are both connected to a transfer box 4, and a delivery pump 9 is provided at the liquid outlet end of the auxiliary material tank group. The raw liquid in the auxiliary material tank group and the concentrated preparation tank 5 is pumped into the transfer box 4, and after contact, it is pumped into the concentrated preparation tank 5 through the first delivery pipe 6. The design of the transfer box 4 is adopted to achieve that each raw liquid is initially fused before entering the concentrated preparation tank 5 without affecting the feeding speed, thereby reducing the stirring time of the concentrated preparation tank 5.

[0035] like Figure 2 As shown, the transfer box 4 includes a box body 41, and a cover body is arranged on the top of the box body 41. Both the cover body and the box body 41 are made of stainless steel. A stirring paddle 49 is rotatably connected to the liquid outlet end of the auxiliary material tank group in the box body 41, and the stirring paddle 49 is rotatably connected between the cover body and the box body 41; Figure 4 As shown, the stirring paddle 49 is arranged on a main shaft, and the blades are preferably three, and each blade is twisted and fixed on the main shaft. In implementation, when the auxiliary liquid in the auxiliary material tank group is pumped into the box body 41, the high-speed flowing auxiliary liquid impacts the surface of the stirring paddle 49, driving the stirring paddle 49 to rotate and stir the various auxiliary liquids, and the first delivery pipe 6 pumps the stirred liquid in the box body 41 into the concentration tank 5, realizing the pre-stirring effect during the pumping and feeding process.

[0036] like Figure 1 and Figure 5As shown, the auxiliary material tank group includes a storage barrel 1, a first batching barrel 2 and a second batching barrel 3; wherein, the first batching barrel 2 can be multiple, and several first batching barrels 2 are set according to actual use requirements. The output end of the storage barrel 1 is connected to the second delivery pipe 7, and the output end of the first batching barrel 2 is provided with a third delivery pipe 8; wherein, when there are multiple first batching barrels 2, the liquid outlet end of each batching barrel 2 is connected to the third delivery pipe 8. The auxiliary liquid pumped out of the second delivery pipe 7 and the third delivery pipe 8 impacts on the stirring paddle 49, and the output end of the second batching barrel 3 is provided with a fourth delivery pipe 10. The auxiliary liquid pumped out of the fourth delivery pipe 10 impacts the auxiliary liquid on the flow path of the first delivery pipe 6; when the mixed auxiliary liquid after stirring flows to the first delivery pipe 6, the auxiliary liquid pumped out of the fourth delivery pipe 10 impacts on the flowing mixed auxiliary liquid, accelerates the flow rate of the mixed auxiliary liquid, and makes the two auxiliary liquids pre-mixed by impact. The above-mentioned design method is adopted, so that the auxiliary liquid undergoes a staged two-stage mixing in the box body 41, and self-mixing is performed while ensuring the flow rate of the liquid.

[0037] like Figure 2 and Figure 3 As shown, the second delivery pipe 7 and the third delivery pipe 8 are connected to the box body 41 at an angle and form an inner angle α, wherein 30°<α<90°. In this embodiment, the angle α is preferably 45°. The connection positions of the second delivery pipe 7 and the third delivery pipe 8 with the box body 41 are separately arranged, for example, the second delivery pipe 7 is arranged on one side of the box body 41, and the third delivery pipe 8 is arranged on the other side of the box body 41, forming two impact flows to impact the stirring paddle 49.

[0038] like Figure 2 and Figure 3 As shown, a partition is provided in the box 41, which is provided on the flow path and divides the box 41 into a first compartment 46 and a second compartment 47 that are connected. The stirring paddle 49 is located in the first compartment 46, and the first delivery pipe 6 is connected to the second compartment 47. By providing the partition, the flow direction of the flow path can be changed, the flow path can be lengthened, the flow time of the liquid can be increased, and the mixing effect of the flow state can be improved.

[0039] The partitions include a first partition 42 and a third partition 44. In the top view projection, the length of the third partition 44 is shorter than that of the first partition 42. One end of the first partition 42 and the third partition 44 is a fixed end and is fixed to the wall of the box body 41, and the other end is a free end and a gap is formed between the wall of the box body 41. The mixed liquid is blocked by the first partition 42 and the third partition 44 and changes direction, and continues to flow through the gap.

[0040] The end of the box body 41 located at the first compartment 46 is designed to be arc-shaped, and the free end of the first partition plate 42 is bent toward the first compartment 46 to form a curved plate. The curved plate and the end are designed to be arc-shaped so that the first compartment 46 forms a nearly circular shape in a top view projection, so that when the auxiliary liquid drives the stirring paddle 49 to rotate in the first compartment 46, the auxiliary liquid can smoothly rotate in the first compartment 46. The gap between the first partition plate 42 and the wall of the box body 41 is the liquid outlet.

[0041] The first partition 42 and the third partition 44 are arranged to form a third compartment 48; the partition also includes a second partition 43, which is located in the third compartment 48 and divides the third compartment 48 into a circulation channel, and the circulation channel includes a first channel and a second channel formed on both sides of the second partition 43; wherein the first channel is connected to the first compartment 46, and the second channel is connected to the second compartment 47. An arc groove 45 is arranged between the first partition 42 and the third partition 44, and the arc groove 45 is formed between the first channel and the second channel, so that the circulation channel is "U" shaped. The fourth delivery pipe 10 is connected to the first channel. The mixed auxiliary liquid flowing out of the first compartment 46 enters the circulation channel. When entering the first channel, the auxiliary liquid pumped out by the fourth delivery pipe 10 impacts the flowing mixed auxiliary liquid, accelerating the flow speed of the mixed auxiliary liquid. The accelerated and mixed auxiliary liquid is redirected by the arc groove 45 and flows into the second channel and then into the second compartment 47.

[0042] Working principle: The auxiliary liquid in the storage barrel 1 and the first batching barrel 2 is pumped into the first compartment 46 through the second delivery pipe 7 and the third delivery pipe 8, and two impact flows are formed to impact the stirring paddle 49 to rotate the stirring paddle 49, and the two auxiliary liquids are blended and mixed during the rotation. The mixed auxiliary liquid flowing out of the first compartment 46 enters the circulation channel. When entering the first channel, the auxiliary liquid in the second batching barrel 3 pumped out by the fourth delivery pipe 10 impacts the flowing mixed auxiliary liquid, accelerating the flow speed of the mixed auxiliary liquid. The accelerated and mixed auxiliary liquid is redirected by the arc groove 45 and flows into the second channel and then into the second compartment 47, and flows into the first delivery pipe 6, and finally pumped into the concentrated preparation tank 5 by the delivery pump 9 for stirring and mixing.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
