Description

TECHNICAL FIELD

[0001] The utility model mainly relates to a kind of foamed material foaming machine. BACKGROUND

[0002] Foaming machine, also known as foam generator, is a kind of equipment for making foam by foaming agent to a certain concentration of aqueous solution. Foaming agent itself cannot automatically become foam, and must be mechanically acted by foaming machine to become foam. It is a kind of equipment specially used to generate foam, which usually uses chemical reaction or physical reaction to manufacture bubbles and form foamed material. However, the foaming machine used at present is not uniform in stirring, and the stirring efficiency is poor, which reduces the working efficiency of the device. UTILITY MODEL CONTENTS

[0003] To solve the above problems, the utility model provides a new structure scheme, and the foamed material foaming machine adopts the following technical scheme:

[0004] A foamed material foaming machine, comprising a shell, a stirring device, an exhaust disc and a fan, wherein the shell has a cavity, and the stirring device extends into the cavity;

[0005] The stirring device comprises a rotating shaft, a foaming wheel and a motor, the fan and the motor are installed at the top end of the shell, the foaming wheel is installed at the bottom end of the rotating shaft, and the rotating end of the motor extends into the cavity and is connected with the rotating shaft to drive the foaming wheel to rotate by the motor;

[0006] The exhaust disc is of hollow structure, and the exhaust disc extends out of a plurality of exhaust pipes, the exhaust pipes are provided with a plurality of air holes, and the fan is connected with the exhaust disc through an air pipe; the exhaust disc is arranged at the bottom of the foaming wheel.

[0007] Preferably, a frame is arranged in the cavity, and the air pipe is fixed in the cavity by the frame.

[0008] Preferably, an air duct is arranged in the exhaust pipe, and the air holes are connected with the exhaust disc through the air duct.

[0009] Preferably, the first end of the air duct is connected with the air hole, the end of the air duct is connected with the exhaust disc, and the diameter of the air duct gradually decreases from the end to the first end.

[0010] Preferably, the bottom of the exhaust disc is provided with an opening for the air pipe to enter, so as to provide air flow for the exhaust pipe.

[0011] Preferably, a support is arranged at the bottom of the cavity to support and fix the exhaust disc.

[0012] Compared with the background art, the utility model has the following beneficial effects:

[0013] This utility model relates to a foam material foaming machine. An exhaust plate is located below the foaming wheel. The foaming wheel, driven by a motor, shears the air bubbles below at high speed, breaking them into smaller bubbles, thereby increasing the gas-liquid contact area and mixing effect. Mechanical stirring ensures thorough mixing of gas and liquid, forming foam. During the stirring process, the bubbles are continuously broken and reassembled, resulting in a more uniform distribution of gas and liquid. Simultaneously, the bursting of bubbles generates localized turbulence and convection, which helps to break up stratification in the liquid, making the liquid more uniformly mixed. Furthermore, the bursting of bubbles also generates tiny shock waves, further promoting liquid flow and mixing. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] The preferred embodiment provided by this utility model is as follows: Figs. 1-6 As shown, a foam material foaming machine includes a shell 1, a stirring device 2, an exhaust plate 3, and a fan 4. The shell 1 has a cavity 11, and the stirring device 2 extends into the cavity 11.

[0024] The stirring device 2 includes a rotating shaft 5, a foaming wheel 6, and a motor 7. The foaming wheel adopts a conventional impeller structure. The fan 4 and the motor 7 are installed at the top of the housing 1, and the foaming wheel 6 is installed at the bottom of the rotating shaft 5. The rotating end of the motor 7 extends out of the cavity 11 and is connected to the rotating shaft 5 so as to drive the foaming wheel 6 to rotate through the motor 7.

[0025] The exhaust plate 3 is a hollow structure, and several exhaust pipes 31 extend from the exhaust plate 3. Several air holes 32 are arranged on the exhaust pipes 31. The fan 4 is connected to the exhaust plate 3 through the air pipes 41. The exhaust plate 3 is located at the bottom of the foaming wheel 6.

[0026] A frame 12 is provided inside the cavity 11. The air duct 41 is fixed in position inside the cavity 11 by the frame 12. The frame is an arc-shaped pressure piece that is welded to the wall of the cavity. The air duct passes through the frame.

[0027] The exhaust pipe 31 is provided with an air duct 33, and the air hole 32 is connected to the exhaust plate 3 through the air duct 33. The first end of the air duct 33 is connected to the air hole 32, and the second end of the air duct 33 is connected to the exhaust plate 3. The diameter of the air duct 33 gradually decreases from the second end to the first end in order to increase the jet rate of the exhaust plate 3 and reduce the bubble size.

[0028] The bottom of the exhaust plate 3 is provided with an opening 34 for the air pipe 41 to be connected to, so as to provide airflow to the exhaust pipe 31. The bottom of the cavity 11 is equipped with a bracket 35 to support and fix the exhaust plate 3. The bracket adopts a conventional circular frame structure.

[0029] Working principle: The fan 4 draws air into the exhaust plate 3 through the duct 41. The airflow in the exhaust plate 3 is then transported to each exhaust pipe 31 through the duct 33 and discharged from the exhaust plate 3 through the air hole 32, forming bubbles. The air inlet of the duct 41 is higher than the solution in the cavity 11, so backflow will not occur. The exhaust plate 3 is located below the foaming wheel 6. The foaming wheel 6, driven by the motor 7, shears the bubbles below at high speed, breaking them into smaller bubbles, thereby increasing the gas-liquid contact area and mixing effect. Mechanical stirring ensures that the gas and liquid are fully mixed to form foam. During the stirring process, the bubbles are constantly broken and reassembled, resulting in a more uniform distribution of gas and liquid. At the same time, the bursting of bubbles generates local turbulence and convection, which helps to break the stratification in the liquid and make the liquid more uniformly mixed. In addition, the bursting of bubbles also generates small shock waves, further promoting the flow and mixing of the liquid.
