Description

Technical Field

[0001] The utility model relates to the technical field of foam light soil foaming processing, in particular to a foam light soil foaming machine with a liquid surface visualization function. Background Art

[0002] Foamed lightweight soil, also known as foamed concrete, foamed lightweight concrete or bubble-mixed lightweight soil, refers to a lightweight material with many pores formed by preparing foaming agents into foam using physical or chemical methods, then mixing the foam into the evenly stirred cement slurry (additives or admixtures may be added) in a certain proportion, and hardening through physical and chemical effects. Among them, foam is an important component of foamed lightweight soil, and its performance is also a key factor in determining the quality of foamed lightweight soil molding.

[0003] At present, the main way to produce foam in the engineering industry is to mix the foaming agent diluent under the action of high-pressure air in the foaming machine. No matter what kind of foam lightweight soil foaming machine is used, air is introduced into the foaming agent diluent to produce foam. Due to the action of high-pressure air, the foaming machine must be closed and fixed during processing, so it is impossible to accurately grasp the specific content and liquid level of the foaming agent diluent in the foaming machine, and it is impossible to change the dilution ratio of the foaming agent according to production needs, which makes the foam produced later often have problems such as uneven stability and large density differences. Utility Model Content

[0004] The utility model aims to solve the problem that the existing foam lightweight soil foaming machine works under closed and fixed working conditions, and the specific content and liquid level of the foaming agent dilution liquid in the foaming machine cannot be accurately grasped, resulting in the produced foam being not uniform and stable and the density difference being large, and to provide a foam lightweight soil foaming machine with a visual liquid level function.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A foam lightweight soil foaming machine with a visualized liquid level function comprises a liquid storage tank, a foaming tube, and an air compressor, wherein the air compressor is respectively connected to the liquid storage tank and the foaming tube, the foaming tube is connected to the liquid storage tank, a first pipeline is arranged at the bottom of the liquid storage tank, a liquid storage tank valve is arranged at a position of the first pipeline close to the liquid storage tank, a liquid storage tank discharge valve is arranged at a position of the first pipeline away from the liquid storage tank, a transparent tube is arranged between the liquid storage tank valve and the liquid storage tank discharge valve, and the transparent tube is arranged to extend upward.

[0007] The foam light soil foaming machine with a visualized liquid level function provided by the utility model cleverly utilizes the communicating vessel principle, and adds a first pipeline and a transparent tube to the lower part of the liquid storage tank of the foaming machine to form a communicating vessel. During foaming, the liquid storage tank valve and the liquid storage tank drain valve can be closed to ensure that the liquid storage tank is a closed environment. After foaming for a period of time, the foaming can be suspended, and the liquid storage tank valve is opened to connect the transparent tube with the liquid storage tank. By observing the transparent tube, the liquid level of the foaming agent diluent in the liquid storage tank of the foaming machine can be accurately grasped, and the supply of the foaming agent diluent can be quickly understood. The foam produced remains uniform and stable with a small density difference, thereby improving the production efficiency and quality of the foam prepared by the foam light soil foaming machine. In addition, when the foaming machine stops using, the waste liquid can be conveniently discharged by opening the liquid storage tank valve and the liquid storage tank drain valve, and the waste liquid in the foaming machine can be quickly removed. The foaming machine has a simple structure, is easy to operate, and is highly practical.

[0008] Optionally, the height of the highest point of the transparent tube is greater than or equal to the height of the liquid storage tank.

[0009] With this structural setting, when the liquid level in the liquid storage tank is high, even if the liquid level approaches or reaches the top of the liquid storage tank, the actual height of the liquid level can still be clearly observed by setting the transparent tube higher than the liquid storage tank. This can greatly expand the scope of liquid level visualization and ensure safe operation.

[0010] Optionally, a scale is provided on the transparent tube.

[0011] With this structural setting, the operator does not need to rely solely on visual observation, but can use a ruler to directly obtain the accurate liquid level reading of the liquid in the storage tank, avoiding the errors and reading difficulties caused by visual observation alone.

[0012] Optionally, a transparent tube valve is provided at the connection between the transparent tube and the first pipeline.

[0013] With this structural setting, liquid and foam may enter the transparent tube due to the connection between the transparent tube and the liquid storage tank. The transparent tube valve can be set to isolate the transparent tube from the liquid storage tank, which is convenient for cleaning and maintenance of the transparent tube to avoid affecting the liquid level observation. Closing the liquid storage tank valve and opening the transparent tube valve and the liquid storage tank drain valve can isolate the transparent tube from the liquid storage tank and quickly drain the liquid in the transparent tube.

[0014] Optionally, the horizontal height difference among the valve of the liquid storage tank, the valve of the transparent tube, and the valve of the liquid storage tank discharge valve is less than 5 cm.

[0015] With this structural setting, the three valves can be located on the same horizontal plane, and the operator can see and operate the three valves at once within the same line of sight and operating range, which is convenient and efficient, and reduces the complexity of operation. This setting is also conducive to the unified layout of connecting pipelines, reducing pipeline distortion and floor space, and contributing to the simplicity and rationality of the entire system layout.

[0016] Optionally, the air compressor is connected to the liquid storage tank through a second pipeline, the air compressor is connected to the foaming tube through a third pipeline, the foaming tube is connected to the liquid storage tank through a fourth pipeline, the third pipeline is installed with an air flow regulating valve, the fourth pipeline is installed with a foaming liquid flow regulating valve, and the foaming tube is located between the air flow regulating valve and the foaming liquid flow regulating valve.

[0017] With this structural setting, flow regulating valves are separately set on the gas pipeline and the liquid pipeline, which can accurately control the air flow and liquid flow entering the foaming tube respectively, adjust the ratio between the two, and optimize the foaming quality.

[0018] Optionally, the air flow regulating valve and the foaming liquid flow regulating valve are symmetrically arranged with the foaming tube as an axis, and the horizontal height difference between the air flow regulating valve and the foaming liquid flow regulating valve is less than 5 cm.

[0019] With this structural setting, this symmetrical arrangement allows air and liquid to flow into the foaming tube in a relatively symmetrical manner, forming a symmetrical flow field structure. This flow field is conducive to the full mixing and uniform foaming of air and liquid, improving the uniformity of foam. At the same time, this setting also makes it easier for operators to clearly observe and operate the two valves within the same line of sight, simplifying the operation process.

[0020] Optionally, a foaming tube drain valve is provided at the bottom of the foaming tube.

[0021] With this structural arrangement, during the foaming process, some foam, liquid or other impurities may remain in the foaming tube. The foaming tube drain valve can be easily discharged to thoroughly clean the foaming tube and avoid affecting the foaming quality.

[0022] Optionally, a liquid filling port is provided at the top of the liquid storage tank, and a liquid filling port valve is arranged in the liquid filling port.

[0023] With this structural setting, a special liquid filling port is opened, and the operator can easily add the required foaming agent diluent into the liquid storage tank through this port. A valve is set at the liquid filling port, which can be closed when no liquid is added to keep the liquid storage tank in a closed state.

[0024] Optionally, a foaming outlet is opened at the top of the foaming tube.

[0025] With this structural arrangement, the foam outlet at the top of the foaming tube can be directly connected to a foam collecting device or a conveying pipeline, so that fresh foam can be smoothly guided to the downstream process.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0027] 1.

[0039] Example 1

[0040] like Figure 1 As shown, a foam lightweight soil foaming machine with a visualized liquid level function includes a liquid storage tank 1, a foaming tube 2, and an air compressor 3. The air compressor 3 is connected to the liquid storage tank 1 through a second pipeline 102, the air compressor 3 is connected to the foaming tube 2 through a third pipeline 103, and the foaming tube 2 is connected to the liquid storage tank 1 through a fourth pipeline 104.

[0041] A first pipeline 101 is provided at the bottom of the liquid storage tank 1, a liquid storage tank valve 201 is provided at a position of the first pipeline 101 close to the liquid storage tank 1, a liquid storage tank discharge valve 202 is provided at a position of the first pipeline 101 far from the liquid storage tank 1, a transparent tube 4 is provided between the liquid storage tank valve 201 and the liquid storage tank discharge valve 202, and the transparent tube 4 is extended upwardly. Here, the transparent tube 4 is extended upwardly specifically means that the transparent tube 4 is provided from the position where the first pipeline 101 intersects, along, for example Figure 1 The transparent tube 4 is arranged to extend upward in the direction perpendicular to the first pipeline 101. Of course, the transparent tube 4 can also extend obliquely upward from the position where it intersects with the first pipeline 101. It can be foreseen that the transparent tube 4 can be a glass tube or an acrylic tube, etc., as long as its transparency allows the operator to read the height of the liquid level in the tube through the tube body; the height of the transparent tube 4 can be lower than the height of the liquid storage tank 1, but it is more preferable that the height of the highest point of the transparent tube 4 is greater than or equal to the height of the liquid storage tank 1. In this way, when the liquid level in the liquid storage tank 1 is high, even if the liquid level approaches or reaches the top of the liquid storage tank 1, by setting the transparent tube 4 higher than the liquid storage tank 1, the actual height of the liquid level can still be clearly observed. This can greatly expand the scope of liquid level visualization and ensure safe operation.

[0042] Furthermore, a transparent tube valve 203 is provided at the connection between the transparent tube 4 and the first pipeline 101, that is, Figure 1As shown, on the first pipeline 101, a liquid storage tank valve 201, a transparent tube valve 203, and a liquid storage tank drain valve 202 are sequentially arranged from the liquid storage tank 1 to the direction away from the liquid storage tank 1. Since the transparent tube 4 is connected to the liquid storage tank 1, liquid and foam may enter the transparent tube 4. The transparent tube valve 203 can be arranged to isolate the transparent tube 4 from the liquid storage tank 1, so as to facilitate the cleaning and maintenance of the transparent tube 4 and avoid affecting the liquid level observation. Closing the liquid storage tank valve 201 and opening the transparent tube valve 203 and the liquid storage tank drain valve 202 can isolate the transparent tube 4 from the liquid storage tank 1 and quickly discharge the liquid in the transparent tube 4.

[0043] Further, such as Figure 1 As shown, the horizontal height difference between the liquid storage tank valve 201, the transparent tube valve 203, and the liquid storage tank discharge valve 202 is less than 5 cm. Preferably, the liquid storage tank valve 201, the transparent tube valve 203, and the liquid storage tank discharge valve 202 are all located at the same horizontal plane. The three valves are located at the same horizontal plane, and the operator can see and operate the three valves at one time within the same line of sight and operating range, which is convenient and efficient, and reduces the complexity of operation. Such a setting is also conducive to the unified layout of connecting pipelines, reducing the distortion and floor space of the pipelines, and contributing to the simplicity and rationality of the overall system layout.

[0044] Further, such as Figure 1 As shown, an air flow regulating valve 204 is installed on the third pipeline 103, a foaming liquid flow regulating valve 205 is installed on the fourth pipeline 104, the foaming tube 2 is located between the air flow regulating valve 204 and the foaming liquid flow regulating valve 205, and a foaming tube drain valve 206 is also provided at the bottom of the foaming tube 2. By separately providing flow regulating valves on the air delivery pipeline and the liquid delivery pipeline, the air flow and liquid flow entering the foaming tube 2 can be accurately controlled respectively, and the ratio between the two can be adjusted to optimize the foaming quality.

[0045] During the foaming process, some foam, liquid or other impurities may remain in the foaming tube 2. The foaming tube drain valve 206 is provided to conveniently discharge these residues, and the foaming tube 2 is thoroughly cleaned to avoid affecting the foaming quality.

[0046] Furthermore, the air flow regulating valve 204 and the foaming liquid flow regulating valve 205 are symmetrically arranged with the foaming tube 2 as the axis, and the horizontal height difference between the air flow regulating valve 204 and the foaming liquid flow regulating valve 205 is less than 5 cm. Preferably, the air flow regulating valve 204 and the foaming liquid flow regulating valve 205 are located at the same horizontal plane, that is, Figure 1The air flow regulating valve 204 is arranged on the left side of the foaming tube 2, and the foaming liquid flow regulating valve 205 is arranged on the right side of the foaming tube 2. This symmetrical arrangement allows air and liquid to flow into the foaming tube 2 in a relatively symmetrical manner, forming a symmetrical flow field structure. This flow field is conducive to the full mixing and uniform foaming of air and liquid, and improves the uniformity of foam. At the same time, this arrangement also makes it easy for operators to clearly observe and operate the two valves within the same line of sight, simplifying the operation process.

[0047] Furthermore, a liquid adding port 11 is provided at the top of the liquid storage tank 1 , a liquid adding port valve 207 is provided in the liquid adding port 11 , and a bubble outlet 21 is provided at the top of the bubble tube 2 .

[0048] A special liquid adding port 11 is provided, and the operator can easily add the foaming agent and water into the liquid storage tank 1 through the liquid adding port 11 according to a certain dilution ratio. The liquid adding port 11 is provided with a liquid adding port valve 207, which can be closed when no liquid is added to keep the liquid storage tank 1 in a sealed state. The foam outlet 21 at the top of the foaming tube 2 can be directly connected to a foam collecting device or a conveying pipeline to smoothly guide the fresh foam to the downstream process.

[0049] In this embodiment, the liquid storage tank valve 201, the liquid storage tank discharge valve 202, and the transparent tube valve 203 can all use ball valves.

[0050] When using the foam lightweight soil foaming machine with a visualized liquid level function provided in this embodiment, the liquid filling port valve 207 can be opened first, and a certain mass of foaming agent and water can be weighed in sequence according to a certain dilution ratio and poured into the liquid storage tank 1 from the liquid filling port 11, and then the liquid filling port valve 207 can be closed; the air compressor 3 is turned on, and air is introduced into the foaming liquid dilution liquid under the action of pressure, so that the generated foam is discharged from the bubble outlet 21 of the foaming tube 2.

[0051] During foaming, the foaming tube drain valve 206 should be in a closed state. When the foaming machine is stopped, the foaming tube drain valve 206 is opened to discharge the waste liquid in the foaming tube 2, and closed again when in use;

[0052] During foaming, the air flow regulating valve 204 can be in a fully open state, and the density of the foam (referring to the wetness of the foam) can be controlled by adjusting the size of the opening of the foaming liquid flow regulating valve 205; the larger the opening of the foaming liquid flow regulating valve 205, the greater the foam density, that is, the wetter the foam; the smaller the opening of the foaming liquid flow regulating valve 205, the smaller the foam density, that is, the drier the foam. If the amount of foam is very small, and the foam rushes out from the bubble outlet 21 in streams, it means that too much air has been added, with more gas and less water. At this time, you can check whether there is leakage in various parts of the pipeline. If there is no abnormality, slowly reduce the air flow regulating valve 204 until the foam is normal; if the foam formed is an emulsion, it means that there is less gas and more liquid or the dilution multiple of the foaming liquid is too large; if the dilution of the foaming agent is normal, check whether the pipeline and pipe fittings are leaking; if it is normal, reduce the foaming liquid flow regulating valve 205 until the foam is normal;

[0053] During foaming, the liquid storage tank valve 201, the liquid storage tank discharge valve 202, and the transparent tube valve 203 should be in a closed state. When foaming is paused, the liquid storage tank valve 201 and the transparent tube valve 203 are opened, and the liquid level of the foaming agent diluent in the liquid storage tank 1 can be dynamically grasped by observing the height of the liquid level in the transparent tube 4. When foaming needs to be continued, the liquid storage tank valve 201, the liquid storage tank discharge valve 202, and the transparent tube valve 203 still need to be kept in a closed state.

[0054] When the foaming machine is stopped, the liquid storage tank valve 201, the liquid storage tank discharge valve 202 and the transparent tube valve 203 can be opened to discharge the waste liquid in the liquid storage tank 1 and the transparent tube 4.

[0055] The foam light soil foaming machine with a visualized liquid level function provided in this embodiment cleverly utilizes the principle of a communicating vessel, and a first pipeline 101 and a transparent tube 4 are added to the lower part of the foaming machine liquid storage tank 1 to form a communicating vessel. When foaming, the liquid storage tank valve 201 and the liquid storage tank discharge valve 202 can be closed to ensure that the liquid storage tank 1 is a closed environment. After a period of foaming, the foaming can be suspended, and the liquid storage tank valve 201 is opened to connect the transparent tube 4 with the liquid storage tank 1. By observing the transparent tube 4, the liquid level of the foaming agent diluent in the foaming machine liquid storage tank 1 can be accurately grasped, and the supply of the foaming agent diluent can be quickly understood. Whether the supply is sufficient, the foam produced remains uniform and stable and the density difference is small, thereby improving the production efficiency and quality of the foam prepared by the foam light soil foaming machine. In addition, when the foaming machine stops using, by opening the liquid storage tank valve 201 and the liquid storage tank discharge valve 202, the waste liquid is conveniently discharged, and the waste liquid in the foaming machine is quickly removed. The foaming machine provided in this embodiment has a simple structure, convenient operation, and strong practicality.

[0057] like Figure 1 , 2As shown, based on Example 1, the foam lightweight soil foaming machine with a visual liquid level function provided in this embodiment is also provided with a scale 41 on the transparent tube 4. With this structural setting, the operator does not need to rely solely on naked eye observation, but can directly obtain the accurate liquid level reading of the liquid in the liquid storage tank 1 with the help of the scale 41, thereby avoiding the errors and reading difficulties caused by visual observation alone.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
