[0001] The utility model belongs to the technical field of paper production, and particularly relates to a solid-liquid mixing nozzle for a pneumatic conveyor. Background Art
[0002] In the modern paper production process, the efficient and uniform mixing of starch and water is one of the key links to ensure paper quality and production efficiency. The traditional mixing method is usually to pour starch and water into a mixing tank in a certain ratio, and then make the starch dissolve in the water by rapid stirring. The whole device has a high-precision requirement for the stirring system to ensure a strong and uniform stirring force so that the starch and water can be fully mixed. The whole process takes a long time and consumes a high amount of energy.
[0003] Therefore, there is an urgent need for a solid-liquid mixing nozzle for a pneumatic conveyor with low energy consumption and high efficiency, which can directly mix water and starch when using a pneumatic conveyor to convey starch into a mixing tank. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a solid-liquid mixing nozzle for a pneumatic conveyor, which can directly mix water and starch when using a pneumatic conveyor to convey starch into a mixing tank, and improve the mixing efficiency of starch and water.
[0005] To achieve the above object, the technical solution adopted by the utility model is: a solid-liquid mixing nozzle for a pneumatic conveyor, including a first housing, a second housing attached to the first housing, and a third housing attached to the second housing;
[0006] Wherein, a first cavity is formed between the first housing and the second housing, a second cavity is formed between the second housing and the third housing, a first water inlet communicating with the first cavity is arranged on the first housing, and a second water inlet communicating with the second cavity is arranged on the second housing;
[0007] A number of first passages for communicating the first cavity are arranged on the second housing and the third housing, a number of second passages for communicating the second cavity are arranged on the third housing, and the first passages and the second passages are arranged in a staggered manner;
[0008] A number of the first passages and the second passages are distributed in a circular pattern along the same central axis, and both the first passages and the second passages are spiral, and their spiral directions are opposite;
[0009] A central pipe is arranged in the middle of the first housing, one end of the central pipe sequentially passes through the first cavity, the second cavity and the third housing, and an interface capable of connecting with a pneumatic conveyor is arranged at the other end of the central pipe.
[0010] Optionally, a number of groups of corresponding ear seats are provided on the first housing, the second housing and the third housing, and bolts are inserted through each group of ear seats.
[0011] Optionally, O-ring seals are provided between the first housing and the second housing, between the second housing and the third housing, between the second housing and the central axis tube, and between the third housing and the central axis tube.
[0012] Optionally, two groups of O-ring seals are provided between the second housing and the third housing, and the two groups of O-ring seals are respectively placed on the inner circumference and the outer circumference of a number of groups of the first passages.
[0013] Optionally, one end of the central axis tube extends towards the side away from the third housing, and a tapered nut that can abut against the third housing is threadedly connected to the central axis tube.
[0014] Optionally, the cross-sections of the first passage and the second passage are flat.
[0015] Optionally, the first housing, the second housing, and the third housing are made of stainless steel.
[0016] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: The first water inlet and the second water inlet can be connected to water, and the interface can be connected to the output end of the pneumatic conveyor.

[0025] As Figures 1-4 shown, a solid-liquid mixing nozzle for a wind conveyor includes a first housing 1, a second housing 2 attached to the first housing 1, and a third housing 3 attached to the second housing 2;
[0026] Wherein, a first cavity 101 is formed by surrounding between the first housing 1 and the second housing 2, a second cavity 102 is formed by surrounding between the second housing 2 and the third housing 3, a first water inlet 201 communicating with the first cavity 101 is provided on the first housing 1, and a second water inlet 202 communicating with the second cavity 102 is provided on the second housing 2;
[0027] A plurality of first passages 301 capable of communicating with the first cavity 101 are provided on the second housing 2 and the third housing 3, and a plurality of second passages 302 capable of communicating with the second cavity 102 are provided on the third housing 3. The first passages 301 and the second passages 302 are arranged in a staggered manner.
[0028] The plurality of first passages 301 and second passages 302 are both distributed in a circular pattern along the same central axis. Both the first passages 301 and the second passages 302 are spiral, and their spiral directions are opposite.
[0029] A central axis tube 5 is provided in the middle of the first housing 1. One end of the central axis tube 5 sequentially passes through the first cavity 101, the second cavity 102, and the third housing 3. An interface 6 capable of connecting to a pneumatic conveyor is provided at the other end of the central axis tube 5.
[0030] Specifically, the first water inlet 201 and the second water inlet 202 can be connected to water, and the interface 6 can be connected to the output end of the pneumatic conveyor. Since the first passages 301 and the second passages 302 are spiral, the water introduced into the first cavity 101 through the first water inlet 201 will form a swirling water flow in the shape of a whirlwind outside the third housing 3, that is, the first swirling water flow; the water introduced into the second cavity 102 through the second water inlet 202 will form another swirling water flow in the shape of a whirlwind outside the third housing 3, that is, the second swirling water flow; the two swirling water flows formed by the first passages 301 and the second passages 302 can surround the outside of the central axis tube 3 in a staggered and intertwined form, forming a "pipe" composed of water flow; at the same time, since the central axis of the central axis tube 5 coincides with the central axis of the circular distribution of the first passages 301 and the second passages 302; the starch blown out in the central axis tube 5 will diffuse around due to the air pressure change, so that it can quickly dissolve in the water when entering the "pipe" composed of water flow, achieving an efficient mixing effect. In the technical solution, the first cavity 101 and the first passages 301, and the second cavity 102 and the second passages 302 are kept relatively sealed, that is, the flow rates of the two swirling water flows can be changed by controlling the liquid pressure introduced into the first cavity 101 and the second cavity 102, so that the two swirling water flows are intertwined more tightly, preventing the starch from diffusing outward.
[0031] As described above, the pneumatic conveyor is a prior art transportation device that can use air as a transportation medium to transport materials in a closed pipeline and can be used to transport starch in this technical solution. And the pneumatic conveyor can control the supply rate of starch by controlling and adjusting the fan speed, controlling the air volume distribution, etc.
[0032] Further, as Figure 3As shown, for the convenience of assembling the first housing 1, the second housing 2, and the third housing 3, a number of groups of corresponding lugs 8 are provided on the first housing 1, the second housing 2, and the third housing 3, and bolts 9 are inserted through each group of lugs 8.
[0033] In this embodiment, to ensure its sealing performance, O-ring seals 10 are provided between the first housing 1 and the second housing 2, between the second housing 2 and the third housing 3, between the second housing 2 and the central axis tube 5, and between the third housing 3 and the central axis tube 5.
[0034] Among them, to prevent the water in the first passage 301 from entering the second cavity 102 through the gap between the second housing 2 and the third housing 3, two groups of O-ring seals 10 are provided between the second housing 2 and the third housing 3, and the two groups of O-ring seals 10 are respectively placed on the inner circumference and the outer circumference of a number of first passages 301.
[0035] Furthermore, one end of the central axis tube 5 extends towards the side away from the third housing 3, and a tapered nut 11 is threadedly connected to the central axis tube 5 and can abut against the third housing 3. The tapered nut 11 can initially fix the assembly positions among the first housing 1, the second housing 2, and the third housing 3.
[0036] In this technical solution, to increase the area of the initial water intersection region, the cross-sections of the first passage 301 and the second passage 302 are flat.
[0037] Working principle: The first water inlet 201 and the second water inlet 202 can connect to clean water, and the interface 6 can be connected to the output end of the pneumatic conveyor. Since the first passage 301 and the second passage 302 are spiral, the clean water introduced into the first cavity 101 through the first water inlet 201 will form a spiral-shaped water flow outside the third housing 3; the water introduced into the second cavity 102 through the second water inlet 202 will also form another spiral-shaped water flow outside the third housing 3, that is, a spiral water flow; the two spiral water flows formed by the first passage 301 and the second passage 302 can surround the outside of the central axis tube 3 in a staggered and intertwined manner, forming a pipeline composed of water flow; at the same time, since the central axis of the central axis tube 5 coincides with the central axes of the circumferential distributions of the first passage 301 and the second passage 302; the starch blown out from the central axis tube 5 will diffuse around due to the air pressure change, so that it can quickly dissolve into the water when entering the pipeline composed of water flow, achieving an efficient mixing effect.
[0038] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant personnel can completely make various changes and modifications within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and must be determined according to the scope of the claims.
