Description

Technical Field

[0001] This utility model relates to the processing of thermal insulation materials, specifically to a foaming device for thermal insulation pipe materials. Background Technology

[0002] The manufacturing process of air conditioning insulation pipes involves foaming the raw materials using a foaming machine and then introducing them into a tubular mold cavity, where the material is allowed to set. The foaming machine typically uses a gear pump; the rotating gears draw in the raw materials and air from one end of the pump and eject them from the other. During rotation, the gears agitate the materials and air, thus forcing the air into the material.

[0003] The current limitation of this structure is that if the gear volume is too large, more raw material will be sucked in at one time. Similarly, the volume of the sucked-in air mass will also be larger, resulting in a poor dispersion effect on the air mass. This makes it easy for the raw material and air to not mix properly, leading to poor foaming effect. If the gear volume is reduced, the working efficiency of the device will be reduced. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the problems mentioned above, this utility model provides the following technical solution:

[0006] A foaming device for thermal insulation pipe materials, comprising:

[0007] The mixture passes through the gear set and the dispersing zone, which are set up independently;

[0008] The dispersing mechanism located in the dispersing zone is engaged with the gear set for transmission.

[0009] In the above scheme, the mixture of raw materials and air is mixed by gear set after entering the pump body, and then enters the dispersing zone under the structural guidance, and is further dispersed by the dispersing mechanism to achieve full mixing of air and raw materials, and finally discharged from the pump body.

[0010] As a preferred technical solution for a foaming device for thermal insulation pipe materials, the dispersing mechanism operates in a rotating state, and the gear set axle extends to the dispersing area and is connected to the dispersing mechanism.

[0011] In the above scheme, the disintegration mechanism works by rotation and is connected to the gear set, so that it can work with the driving force provided by the gear set, thereby simplifying the structural configuration.

[0012] In a preferred technical solution of a foaming device for thermal insulation pipe materials, the dispersing zone is located on one side of the gear set.

[0013] In the above scheme, this structure ensures that the gear axle extension distance is not too long, thus allowing it to be connected with the disintegration mechanism to further achieve the compactness of the entire device, while reducing the kinetic energy loss of the gear set.

[0014] A preferred technical solution for a foaming device for thermal insulation pipe materials further includes a mixing zone and a shell, wherein the shell is constructed with a partition wall, the dispersing zone and the mixing zone are located on both sides of the partition wall, and the gear set is disposed in the mixing zone.

[0015] In the above scheme, the internal space of the housing is divided into an independent dispersing zone and a mixing zone by the construction of the partition wall. The partition wall can support the gear set to facilitate the installation of the gear set.

[0016] As a preferred technical solution for a foaming device for thermal insulation pipe materials, a through-hole is constructed on the partition wall, and the mixture enters the dispersing zone through the through-hole after passing through the gear set.

[0017] In the above scheme, after the mixture is sucked into the shell, it is squeezed by the gear set to reach the other side of the gear set, and then directly enters the dispersing zone through the through-hole to reduce the travel path length of the mixture.

[0018] As a preferred technical solution for a foaming device for thermal insulation pipe materials, the dispersing component is detachably and fixedly connected to the gear set axle.

[0019] In the above scheme, this structure makes the installation of the gear set and the disintegration mechanism more convenient.

[0020] As a preferred technical solution for a foaming device for thermal insulation pipe materials, the dispersing component includes a bushing with a crushing element fixedly arranged on its periphery, and the bushing is connected to the gear set wheel bushing.

[0021] In the above scheme, the nested connection method makes the process simple and convenient, thus facilitating overall assembly.

[0022] As a preferred technical solution for a foaming device for thermal insulation pipe materials, it also includes a discharge port, and the number of bushings is multiple, with the through port and discharge port located on both sides of the multiple bushings respectively.

[0023] In the above scheme, after the mixture enters the dispersing zone, it needs to completely pass through the dispersing mechanism before leaving the discharge port, so as to ensure that the mixture is thoroughly dispersed.

[0024] As a preferred technical solution for a foaming device for thermal insulation pipe materials, the shell also has detachably connected end caps, which are distributed at least in the dispersing zone and the mixing zone, and the gear set axle is rotatably connected to the end caps.

[0025] In the above scheme, the housing is combined with multiple end caps to form a complete pump housing structure. During assembly, the gear set is inserted into the mixing zone, and its axle passes through the partition wall to reach the dispersing zone. Then, the bushing is put on and the end cap mechanism is installed. This structure makes the assembly process of the entire device simpler and more convenient.

[0026] The beneficial effects of the foaming device for insulation pipe materials provided by this utility model are as follows: with the cooperation of the dispersing mechanism, after the mixture is first mixed by the gear set, the mixture will enter the dispersing zone under the guidance of the pump shell structure, and then be further crushed by the dispersing mechanism to ensure the quality of foaming.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0036] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0037] Reference Figure 1 An embodiment of this utility model provides a foaming device for insulation pipe material, including a pump housing, which has an inlet 8 and an outlet 9. The pump housing includes a shell 1 and end caps 2 at both ends of the shell 1.

[0038] Furthermore, regarding the internal structure of the pump casing, such as Figure 2-7 As shown, the inner side of the housing 1 is constructed with a partition wall 3, which divides the entire internal space of the pump housing into a mixing zone 10 and a dispersing zone 11. The mixing zone 10 is equipped with a gear set 5, which is used to complete the suction of materials and the extrusion of raw materials between air.

[0039] Furthermore, a dispersing mechanism is configured in the dispersing zone 11. The dispersing mechanism includes a bushing 6, and blades 7 are constructed around the bushing 6. One end of the gear shaft of the gear set 5 passes through the partition wall 3 and extends into the dispersing zone 11. The bushing 6 is fitted on the gear shaft, and the inner side of the bushing 6 is splined with the gear shaft, so that the gear set 5 can drive the blades 7 to rotate when it rotates. Such bushings 6 are fitted on the gear shafts of both gears. The two ends of the gear shafts are rotatably connected to the two end covers 2 respectively. Specifically, for the rotatable connection, bearings are installed on the end covers 2 at the corresponding positions, and the gear shafts can be directly inserted into the bearings.

[0040] Furthermore, during the foaming process, air and raw materials are drawn into the mixing zone 10 through the feed inlet 8. The partition wall 3 has a through-hole 4. After being squeezed and mixed by the gear set 5, the mixture enters the dispersing zone 11 through the through-hole 4. The blade 7 further shreds the mixture under the drive of the gears to achieve sufficient air-material mixing. After further mixing, the mixture is discharged through the discharge outlet 9. Since the discharge outlet 9 and the through-hole 4 are located on different sides of the two bushings 6, after the mixture enters the dispersing zone 11 and is discharged, the mixture needs to completely pass through the blade 7 to ensure thorough pulverization and achieve sufficient mixing of raw materials and air.

[0041] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
