Embodiment 1

[0049] See figure 1 , This embodiment provides a low-flow foaming machine for heat preservation at the interface of the heating pipe. The small flow foaming machine includes a storage device 3, a spray gun device 2, a control device 4 and a power supply device 1.

[0050] Among them, the storage device 3 is used to store at least two kinds of foaming materials, and the spray gun device 2 is used to mix the foaming materials stored in the storage device 3 and inject them to the interface requiring heat preservation for foaming and heat preservation. The storage device 3 and the spray gun device 2 are evenly electrically connected to the control device 4. In other words, the storage device 3 and the spray gun device 2 are both controlled by the control device 4, and the power supply device 1 is used to provide electrical energy for work.

[0051] The working voltage of the low-flow foaming machine provided in this embodiment is 220V. Therefore, the power supply device 1 is used to pr...

Embodiment 2

[0159] See Image 6 The low-flow foaming machine provided in this embodiment is based on the technology of the above-mentioned embodiment. Compared with Embodiment 1, the main difference of the low-flow foaming machine provided in this embodiment is:

[0160] Specifically, in this embodiment, the storage device 3 includes a storage barrel with two storage chambers 300, and the two storage chambers are used to store two foaming materials, which also achieves two The independent storage of a kind of foaming material is convenient for transportation and addition.

Embodiment 3

[0162] See Figure 4 with Figure 5 The low-flow foaming machine provided in this embodiment is based on the technology of the above-mentioned embodiment. Compared with Embodiment 1, the main difference of the low-flow foaming machine provided in this embodiment is:

[0163] Such as Figure 4 As shown, specifically, in this embodiment, the first heating assembly 31 is provided with two sets, and the two sets of first heating assemblies 31 are set outside the first storage barrel 30a and the second storage barrel 30b. The first heating assembly 31 is respectively arranged corresponding to the first storage barrel 30a and the second storage barrel 30b. In other words, the two sets of first heating components 31 independently heat the first storage barrel 30a and the second storage barrel 30b, thus realizing the independent heating temperature of the first storage barrel 30a and the second storage barrel 30b. The control can select the best heating temperature according to the tempe...

Abstract

The invention provides a small-flow foaming machine and a foaming method, and relates to the technical field of foaming machines. According to the small-flow foaming machine, at least two kinds of foaming raw material are stored in a material storage device, a control device controls the material storage device and a spray gun device to work cooperatively, and a power supply device is used for providing 220V working voltage. The small-flow foaming machine is simple in structure, the working voltage is 220V, a 220V small generator can be adopted or the small-flow foaming machine can be directlyconnected with 220V mains supply for power supply, and the whole machine is small in size, light in weight, more convenient to transport and suitable for operation in a narrow space; and besides, thedevice is simple and convenient to operate and is not influenced by human factors, so that the foaming quality is stable, the defect of unstable artificial foaming quality is further overcome, and the heat preservation quality and the working efficiency of a connector are improved.

Description

Technical field [0001] The invention relates to the technical field of foaming machines, in particular to a small flow foaming machine and a foaming method. Background technique [0002] At present, my country’s urbanization is developing rapidly, and the corresponding residential area is also increasing sharply. Since the beginning of the 21st century, the area of ​​central heating has increased at a rate of 200 million square meters per year. The direct buried pipelines used to transport heat in cities are also developing The scale is huge. [0003] The thermal insulation of polyurethane prefabricated thermal insulation pipe joints applied to the thermal direct buried pipe network is very important. The joint insulation is carried out at the outdoor construction site. The isocyanate and the combined polyether are mixed in proportion, and the hollow of the joint casing is injected through the pouring hole after full mixing. Cavity. [0004] In order to ensure the foaming quality of...
