Description

Technical Field

[0001] This utility model relates to pipes, and more specifically, to a multi-component permeable PE solid-wall pipe. Background Technology

[0002] In some industrial and agricultural applications, it is necessary to transport multiple raw materials and then mix them to form a mixed reagent for use by the end user. For example, in an integrated water, fertilizer, and pesticide system in agriculture, various components such as fertilizers and pesticides need to be added to the irrigation water to achieve integrated water, fertilizer, and pesticide application. Currently, the common method is to add multiple fertilizers and pesticides to the irrigation water, mix the water with the various reagents, and then transport the mixed water for irrigation. This method requires large storage tanks for pre-storing and mixing the main raw material (water), making the process relatively complex. If the amount of the main raw material used is large, the storage tanks also have significant requirements.

[0003] Therefore, a new type of pipe suitable for transporting various raw materials is needed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-component permeable PE solid wall pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-component permeable PE solid-wall pipe includes an inner tube, an outer tube, and a support portion. The inner tube is sleeved inside the outer tube, and the inner tube and the outer tube are connected and fixed by the support portion. An inner flow channel is formed inside the inner tube, and an outer flow channel is formed between the outer tube and the inner tube. The inner tube has several through holes that penetrate the wall of the inner tube and connect the inner flow channel and the outer flow channel.

[0007] The present invention is further configured such that the support portion includes a plurality of support ribs, each of which is arranged along the length of the pipe.

[0008] The present invention is further configured such that each support rib is distributed in a ring around the inner tube, dividing the outer flow channel into several parts, and forming an outer flow channel between two adjacent support ribs, the inner tube and the outer tube.

[0009] The present invention is further configured such that the supporting ribs are provided in four groups and are arranged in a circular pattern, and the outer flow channel is divided to form four outer flow channels.

[0010] The present invention is further configured such that the inner tube has several sets of through holes, each set of through holes corresponds to each outer layer flow channel, and each outer layer flow channel is connected to the inner layer flow channel.

[0011] The present invention is further configured such that in each group of through holes, each through hole is evenly distributed along the length of the pipe.

[0012] The present invention is further configured such that the through hole has a small opening end and a large opening end, the diameter of the large opening end being larger than the diameter of the small opening end; the small opening end is connected to the inner flow channel, and the large opening end is connected to the outer flow channel.

[0013] The present invention is further configured such that the through hole has a first side and a second side, the first side and the second side are respectively located on both sides of the length direction of the pipe, the first side runs along the radial direction of the pipe, the second side is inclined, and the distance between the first side and the second side gradually increases towards the larger end.

[0014] The present invention is further configured such that the inner tube, the outer tube and the support are integrally formed.

[0015] The present invention is further configured such that the inner tube and the outer tube are arranged coaxially.

[0016] In summary, this utility model has the following beneficial effects:

[0017] By adopting a double-layer structure, a double-layer flow channel can be formed inside the pipe. The main raw material can be transported in the inner flow channel, and the secondary raw material can be transported in the outer flow channel, which can realize the transport of multiple raw materials at the same time. Moreover, through holes are opened in the inner pipe to allow the raw materials to penetrate and mix, so that the raw materials can be mixed during the transport process, reducing the need for subsequent raw material mixing steps.

[0018] By dividing the outer flow channel into multiple outer flow channels, each outer flow channel can be used to transport different auxiliary materials. Furthermore, the outer flow channels are not directly connected to each other, which can avoid direct cross-flow between the outer flow channels. This allows for the simultaneous transport of more types of materials and further reduces the number of transport pipelines.

[0019] The inner layer pipe has a variable diameter structure with through holes. The opening facing the inner layer flow channel is the small opening, and the opening facing the corresponding outer layer branch channel is the large opening. The auxiliary raw materials in the outer layer can enter more easily from the large opening, thus achieving the permeation of the raw materials. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This embodiment discloses a multi-component permeable PE solid-wall pipe, referring to... Figures 1-3 As shown, the tube includes an inner tube 1, an outer tube 2, and a support part 3. The inner tube 1 is fitted inside the outer tube 2, and the inner tube 1 and the outer tube 2 are connected and fixed by the support part 3. The inner tube 1, the outer tube 2, and the support part 3 are integrally formed to create a double-layered tube structure.

[0026] An inner flow channel 10 is formed inside the inner tube 1, and an outer flow channel 20 is formed between the outer tube 2 and the inner tube 1. The different inner and outer flow channels can deliver different reagents.

[0027] Several through holes 4 are provided in the inner tube 1, which penetrate the wall of the inner tube 1 and connect the inner flow channel 10 and the outer flow channel 20. The inner flow channel 10 and the outer flow channel 20 can permeate and mix, thereby reducing the number of mixing steps.

[0028] The inner flow channel 10 is used to transport the main raw material, while the outer flow channel 20 transports the auxiliary raw material. During the transport process, the auxiliary raw material in the outer flow channel 20 can permeate into the inner flow channel 10 through the through holes 4, thereby achieving the permeation and mixing of the auxiliary raw material into the main raw material. Specifically, by adjusting parameters such as the flow rate and pressure of the inner flow channel 10 and the outer flow channel 20, a permeation flow direction mainly from the outer flow channel 20 to the inner flow channel 10 can be formed, allowing the materials to mix during transport and reducing the number of mixing steps.

[0029] Reference Figure 1As shown, the support part 3 includes several support ribs 31, each of which is arranged along the length of the pipe. One side of the support rib 31 is fixedly connected to the outer wall of the inner pipe 1, and the other side is fixedly connected to the inside of the outer pipe 2. All parts are connected to form a whole.

[0030] Each support rib 31 is arranged in a ring around the inner tube 1, dividing the outer flow channel 20 into several parts. An outer flow channel 21 is formed between two adjacent support ribs 31, the inner tube 1 and the outer tube 2. Under normal circumstances, the inner tube 1 and the outer tube 2 are arranged coaxially, and the outer flow channel 21 has a fan-shaped annular structure.

[0031] Reference Figure 1 As shown, the support ribs 31 are arranged in four groups in a circular pattern. The outer flow channel 20 is divided into four outer flow channels 21. The four flow channels 21 are relatively independent and can transport different kinds of auxiliary raw materials in the outer flow channels 21 respectively. In this way, multiple raw materials can be transported simultaneously through the same pipeline, and multiple auxiliary raw materials can be mixed with the main raw material.

[0032] Corresponding to each outer layer flow channel 21, the inner layer tube 1 has several sets of through holes 4, each set of through holes 4 corresponding to each outer layer flow channel 21, and each outer layer flow channel 21 is connected to the inner layer flow channel 10.

[0033] In each group of through holes 4, each through hole 4 is evenly distributed along the length of the pipe, so that when the material is transported along the length, the material in the outer diversion channel 21 can gradually permeate, thereby enabling the mixing of raw materials.

[0034] Furthermore, the through-hole 4 has a small opening 41 and a large opening 42, with the diameter of the large opening 42 being larger than that of the small opening 41; the small opening 41 connects to the inner flow channel 10, and the large opening 42 connects to the outer flow channel 20. The through-hole 4 gradually expands from the corresponding outer flow channel 21 towards the inner flow channel 10, facilitating the permeation of raw material from the outer flow channel 21 into the inner flow channel 10.

[0035] Reference Figure 3 As shown, the through-hole 4 has a first side 43 and a second side 44, which are located on opposite sides of the length of the pipe. The first side 43 runs along the radial direction of the pipe, and the second side 44 is inclined. The distance between the first side 43 and the second side 44 gradually increases towards the larger end 42. The inclined second side 44 can form an inclined guide, which facilitates the permeation of raw materials and reagents during the permeation process.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
