[0002] In the related experiment about transparent soil making, the raw materials usually have fused quartz sand and mixed mineral white oil or epoxy resin and other solid and liquid materials, therefore, in order to ensure the transparency of transparent soil, vacuumizing is one of the important experimental processes, and the existing vacuumizing means is vacuum box, vacuum barrel and the like, and the existing vacuum barrel vacuumizing device is generally composed of a vacuum pump and a vacuum barrel, the function of the vacuum pump is to remove the air in the barrel to generate a vacuum environment, the selection of the pump is usually based on the required vacuum degree and the type of the processed articles. For example, a liquid ring vacuum pump or a rotary vane vacuum pump is used to achieve different vacuum degree requirements. The vacuum barrel part is usually made of stainless steel or high-strength plastic to ensure pressure resistance and corrosion resistance, and common materials include food-grade stainless steel, plastic, silica gel and the like. These materials not only can withstand the pressure difference in the vacuum environment, but also can effectively prevent the pollution of external gas to the articles, and the vacuum barrel is usually equipped with an exhaust valve system, so that air can be injected again through the exhaust valve, or the vacuum environment can be adjusted to meet different requirements. The vacuum barrel device technology is commonly used in many fields such as household food storage, industrial packaging and laboratory environment control.

[0003] The existing vacuum barrel device has high vacuum degree performance and high application performance due to the characteristics of the oil seal type vacuum pump, and in the existing experiment about transparent soil preparation, the vacuumizing equipment used is usually a vacuum barrel with an oil seal type vacuum pump, a vacuum box and the like, but the pump cavity of the oil seal type vacuum pump is filled with vacuum pump oil, which not only serves as a seal, but also plays a role in lubrication and cooling. Therefore, during the operation of the oil seal type vacuum pump, oil vapor backflow, oil mist emission, oil gas carrying or decomposition and other reasons may cause oil gas to be brought into the vacuum barrel, thereby causing oil pollution to the transparent soil sample.

[0004] Therefore, it is necessary to provide a novel transparent soil material preparation process bubble removal vacuumizing device to solve the above technical problems. UTILITY MODEL CONTENTS

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a novel transparent soil material preparation process bubble removal vacuumizing device to solve the problem that oil gas is brought into the vacuum barrel during the operation of the oil seal type vacuum pump, thereby causing oil pollution to the transparent soil sample.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A kind of new transparent soil material preparation process bubble removal vacuumizing device, including: bucket, sealing cover, air release valve, stop valve, pressure gauge, vacuum connection pipe, vacuum pump;

[0008] Two sides of the bucket are equipped with handles, and the top of the bucket is equipped with a sealing cover, the top of the sealing cover is connected with a valve body, the valve body includes an air release valve on the right side and a stop valve on the left side, a pressure gauge is installed on the top of the valve body, the upper end and the lower end of the vacuum connection pipe are respectively connected with the stop valve and the vacuum pump through a connecting pipe and a clamp, an oil mist filter screen is installed at the discharge end of the vacuum pump, two layers of oil mist filter screens are spaced apart, and the oil mist filter screens are connected by bolts.

[0009] In one embodiment, the bucket is made of stainless steel, and the sealing cover is made of transparent acrylic.

[0010] In one embodiment, a digital display vacuum gauge is installed on the top of the sealing cover.

[0011] In one embodiment, the transparent soil in the bucket is pre-debubbled by a pretreatment mechanism, which includes a bracket, a treatment box, a vibration motor, a fixing frame, an air cylinder, a push plate, and a debubbling rod.

[0012] In one embodiment, the bracket is equipped with a fixing frame at the front end, the fixing frame is an L-shaped structure, the horizontal segment of the fixing frame extends above the treatment box, an air cylinder is installed on the top surface of the extended end of the fixing frame, the output end of the air cylinder is connected with a push plate below, the push plate is a disc structure, the bottom surface of the push plate is arranged in a ring array, the debubbling rods are made of acrylic, and the bottom end is a tapered rod structure.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) The oil mist filter screen is provided to collect the mixed oil mist generated by the vacuum pump and air flow, avoiding gas pollution, and the air release valve and the stop valve are provided to manually control the vacuum degree in the vacuum barrel.

[0015] (2) The sealing cover is made of transparent material to more intuitively observe the transparency of the transparent soil sample in the bucket and the bubble discharge process during the vacuumizing process.

[0016] (3) By installing a pressure gauge and a digital vacuum gauge on the sealing cover, this utility model can intuitively judge the vacuum level inside the vacuum tank, and at the same time, it can simultaneously observe and manually control the change in the vacuum level inside the tank.

[0017] (4) By placing a container filled with transparent soil into the treatment box, the transparent soil is pre-vibrated and defoamed. Before vacuum defoaming, the transparent soil is vibrated by using a vibration motor in conjunction with the treatment box. This helps to break the adsorption force between the bubbles and the soil particles, promotes the aggregation and rise of the bubbles, and the vibration can generate shear force and turbulence inside the transparent soil, thereby causing the bubbles to desorb and float to the liquid surface, which helps to improve the efficiency of subsequent vacuum defoaming.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] like Figures 1-2 As shown, the present invention provides a novel defoaming and vacuuming device for the preparation process of transparent soil material, comprising: a barrel body 1, a sealing cap 2, a venting valve 3, a shut-off valve 4, a pressure gauge 5, a vacuum connecting pipe 7, and a vacuum pump 8.

[0025] like Figures 1-2As shown, handles 11 are installed on both sides of the barrel 1, and a sealing cover 2 is installed on the top of the barrel 1. The top of the sealing cover is connected to the valve body. The valve body includes a vent valve 3 on the right side and a shut-off valve 4 on the left side. A pressure gauge 5 is installed on the top of the valve body. The upper and lower ends of the vacuum connecting pipe 7 are connected to the shut-off valve 4 and the vacuum pump 8 respectively through connecting pipes and clamps. An oil mist filter 81 is installed at the discharge end of the vacuum pump 8. The oil mist filter 81 has two layers spaced apart. The oil mist filter 81 is connected by bolts. The oil mist filter 81 collects the mixed oil mist generated by the vacuum pump 8 and the air flow, avoiding gas pollution. The vent valve 3 and the shut-off valve 4 allow the vacuum level in the vacuum barrel to be manually controlled by the inlet and outlet of the gas.

[0026] Preferably, in one embodiment, the barrel 1 is made entirely of stainless steel, and the sealing cap 2 is made entirely of transparent acrylic. By using the transparent material of the sealing cap 2, the transparency of the transparent soil specimen inside the barrel 1 and the process of air bubble discharge during the vacuuming process can be observed more intuitively.

[0027] Preferably, in one embodiment, a digital vacuum gauge 6 is installed on the top of the sealing cover 2. By installing a pressure gauge 5 and a digital vacuum gauge 6 on the sealing cover 2, the vacuum level inside the vacuum tank can be judged intuitively, and the change in the vacuum level inside the tank can be observed and manually controlled simultaneously.

[0028] Preferably, in one embodiment, such as Figures 3-4 As shown, the transparent soil in the barrel 1 undergoes pre-defoaming treatment by the pre-treatment mechanism 9. The pre-treatment mechanism 9 consists of a support 91, a treatment box 92, a vibration motor 93, a fixing frame 94, a cylinder 95, a push plate 96, and a defoaming rod 97. The top of the support 91 has an installation opening, and the treatment box 92 is installed in the installation opening. The treatment box 92 is hollow inside and has an open top. The transparent soil to be defoamed and a container for holding the transparent soil are placed inside the treatment box 92. The vibration motor 93 is installed at the bottom of the treatment box 92. During operation, the transparent soil is pre-vibrated and defoamed by placing the container containing the transparent soil inside the treatment box 92. Before vacuum defoaming, the transparent soil is vibrated by the cooperation of the vibration motor 93 and the treatment box 92. This helps to break the adsorption force between the bubbles and the soil particles, promotes the aggregation and rise of the bubbles, and the vibration can generate shear force and turbulence inside the transparent soil, thereby causing the bubbles to desorb and float to the liquid surface, which helps to improve the processing efficiency of subsequent vacuum defoaming.

[0029] Preferably, in one embodiment, such as Figures 3-4As shown, a fixing frame 94 is installed at the front end of the bracket 91. The fixing frame 94 is an L-shaped structure, with its horizontal section extending to the top of the processing box 92. A cylinder 95 is installed on the top surface of the extended end of the fixing frame 94. The output end of the cylinder 95 is connected to the push plate 96 below. The push plate 96 is a disc structure, with defoaming rods 97 arranged in a ring array on its bottom surface. The defoaming rods 97 are made of acrylic material, with a tapered bottom structure and the bottom end is polished with an arc surface. During operation, the cylinder 95 drives the push plate 96 to move up and down, causing the defoaming rods 97 to exhaust the soil structure inside the processing box 92, forming a reciprocating agitation, which further improves the efficiency of subsequent vacuum processing.

[0030] Working principle of this utility model:

[0031] During operation, the oil mist filter 81 collects the mixed oil mist generated by the vacuum pump 8 and the airflow, preventing gas pollution. The vent valve 3 and shut-off valve 4 allow manual control of the vacuum level in the vacuum tank. A container filled with transparent soil is placed inside the processing tank 92 for pre-vibration defoaming. Before vacuum defoaming, the transparent soil is vibrated in conjunction with the vibration motor 93 and the processing tank 92 to break the adsorption between air bubbles and soil particles, promoting bubble aggregation and rising. Vibration generates shear force and turbulence inside the transparent soil, causing air bubbles to detach and float to the surface, improving the efficiency of subsequent vacuum defoaming. The cylinder 95 drives the push plate 96 to move up and down, causing the defoaming rod 97 to vent the soil structure inside the processing tank 92, creating a reciprocating agitation that further improves the efficiency of subsequent vacuum processing.

[0032] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
