Description

Technical Field

[0001] This utility model belongs to the field of sample preparation device technology, specifically relating to a sample preparation device for microbial solidification of arsenic sandstone. Background Technology

[0002] Microbial solidification of arsenic sandstone is a method that utilizes microbial technology to improve and reinforce the properties of arsenic sandstone. Arsenic sandstone is a type of rock that is easily weathered and eroded, widely distributed in regions such as the Loess Plateau of China. Its loose structure and poor erosion resistance make it prone to soil erosion and geological disasters. This method primarily utilizes enzymes or metabolites, such as calcium carbonate, produced by microorganisms like Bacillus pasteurellii and urea-decomposing bacteria to cement arsenic sandstone particles, enhancing their mechanical properties and erosion resistance. It can be used to reinforce landslide-prone arsenic sandstone slopes, improving stability; reduce soil erosion in arsenic sandstone areas, improving the ecological environment; and prevent and manage geological disasters in arsenic sandstone areas, such as landslides and debris flows.

[0003] In the research and engineering applications of microbially solidified arsenic sandstone, sample preparation devices are key equipment for preparing standardized samples, facilitating laboratory testing and performance evaluation. However, existing sample preparation devices have limited functionality and cannot specifically adjust and control the mixing uniformity of arsenic sandstone particles, bacterial solutions, and reaction solutions, thus affecting the quality of the prepared samples.

[0004] Based on this, a sample preparation device for microbial solidification of arsenic sandstone is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a sample preparation device for microbial solidification of arsenic sandstone, in order to address the shortcomings of the prior art mentioned above.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sample preparation device for microbial solidification of arsenic sandstone, comprising a sample preparation bottom cavity, a sample preparation bottom plate, a sample preparation cylinder and a sample preparation top plate;

[0007] The sample preparation cavity is a cylindrical hollow cavity with an opening at the top. At least four connecting springs are installed at equal intervals on the inner bottom surface of the sample preparation cavity. A sample preparation base plate is sleeved inside the sample preparation cavity, and the top of the connecting spring is engaged with the bottom surface of the sample preparation base plate.

[0008] A sample preparation cylinder is snapped onto the sample preparation base plate. Four sample preparation connecting posts are evenly spaced in a circular pattern on the outer side of the sample preparation cylinder on the sample preparation base plate. The sample preparation top plate is a circular plate, and through holes are respectively provided on the sample preparation top plate at positions corresponding to the four sample preparation connecting posts. The top end of each sample preparation connecting post is sleeved in the through hole, and a locking nut is threaded onto the top end of each sample preparation connecting post. The sample preparation top plate is snapped onto the top end of the sample preparation cylinder by the action of the sample preparation connecting posts and the locking nut, thus completing the sample preparation operation between the sample preparation base plate, the sample preparation cylinder, and the sample preparation top plate.

[0009] As a further explanation of this utility model, the inner diameter of the sample preparation cavity is larger than the diameter of the sample preparation base plate, and multiple rubber buffer blocks are fixed at equal intervals on the top surface of the sample preparation cavity.

[0010] As a further explanation of this utility model, at least two vibration motors are provided on the bottom surface of the sample preparation base plate, and each vibration motor is independently controlled.

[0011] As a further explanation of this utility model, the upper middle section of the sample preparation connecting column is provided with a male thread on the outer side, and the locking nut is provided with a female thread. The locking nut is used in conjunction with the male thread of the sample preparation connecting column through the female thread.

[0012] As a further explanation of this utility model, the length of the sample preparation connecting column is greater than the height of the sample preparation cylinder, the outer diameter of the sample preparation cylinder is smaller than the outer diameter of the sample preparation top plate, and the outer diameter of the sample preparation top plate is smaller than the outer diameter of the sample preparation bottom plate.

[0013] As a further explanation of this utility model, a vacuum port is provided in the middle of the sample preparation top plate.

[0014] As a further explanation of this utility model, the sample preparation top plate is also provided with multiple liquid injection ports, through which bacterial solution or reaction solution is injected into the sample preparation cylinder.

[0015] This utility model has the following advantages compared with the prior art:

[0016] This invention features four connecting springs evenly spaced on the inner bottom surface of a sample preparation cavity. A sample preparation base plate is fitted inside the cavity, and the tops of the connecting springs are engaged with the bottom surface of the base plate. During use, the vibration of a vibrating motor drives the sample preparation base plate and connecting springs to vibrate within the cavity. This ensures uniform mixing of the arsenic sandstone particles, bacterial solution, and reaction solution within the sample preparation cylinder. Furthermore, the vibration process increases the density of the arsenic sandstone particles, improving the overall quality of the prepared sample and facilitating its preparation, subsequent research, and use.

[0017] The sample preparation base plate of this utility model has a circular groove on its inner bottom surface. A sample preparation cylinder is clamped onto the circular groove of the sample preparation base plate. Four sample preparation connecting posts are arranged in a circumferential and equally spaced manner on the outer side of the sample preparation cylinder on the sample preparation base plate. The sample preparation top plate is clamped to the top of the sample preparation cylinder by the action of the sample preparation connecting posts and the locking nut, so that the sample preparation cylinder can be stably placed between the sample preparation base plate and the sample preparation top plate. The sample preparation can be completed between the sample preparation base plate, the sample preparation cylinder and the sample preparation top plate.

[0018] The sample preparation top plate of this invention is equipped with a vacuum interface in the middle, which enables vacuuming during sample preparation. The top plate also has multiple liquid injection ports, through which bacterial solution or reaction solution is injected into the sample preparation cylinder. During use, the appropriate liquid injection port position is selected based on the type and location of the bacterial solution and reaction solution, and the external bacterial solution or reaction solution pipe is connected to the corresponding liquid injection port. All liquid injection ports are closed using a control valve. After the air inside the sample preparation cylinder is extracted using the vacuum interface, the control valve of the liquid injection port connected to the bacterial solution or reaction solution pipe is opened, injecting the bacterial solution and reaction solution into the sample preparation cylinder. This improves the uniformity of the prepared sample and is convenient and practical. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a sample preparation device for microbial solidification of arsenic sandstone, including a sample preparation bottom cavity 1, a sample preparation bottom plate 2, a sample preparation cylinder 4, and a sample preparation top plate 5;

[0025] The sample preparation cavity 1 is a cylindrical hollow cavity with an opening at the top. At least four connecting springs 11 are installed at equal intervals on the inner bottom surface of the sample preparation cavity 1. A sample preparation base plate 2 is sleeved inside the sample preparation cavity 1. The top ends of the connecting springs 11 are engaged with the bottom surface of the sample preparation base plate 2. At least two vibration motors 21 are provided on the bottom surface of the sample preparation base plate 2. Each vibration motor 21 is independently controlled. During use, the vibration of the vibration motor 21 drives the sample preparation base plate 2 and the connecting springs 11 to vibrate in the sample preparation cavity 1. This allows the arsenic sandstone particles in the sample preparation cylinder 4 to be mixed evenly with the bacterial solution and reaction solution. It also increases the density of the arsenic sandstone particles during vibration, which facilitates the improvement of the overall quality of the prepared sample 6 and the completion of the preparation of the sample 6 for subsequent research and use.

[0026] In order to facilitate the vibration of the sample preparation base plate 2 in the sample preparation cavity 1, the inner diameter of the sample preparation cavity 1 is larger than the diameter of the sample preparation base plate 2, and multiple rubber buffer blocks 12 are fixed at equal intervals on the top surface of the sample preparation cavity 1. The rubber buffer blocks 12 can protect the top surface of the sample preparation base plate 2, thereby extending the service life of the sample preparation base plate 2.

[0027] A circular groove is provided on the inner bottom surface of the sample preparation base plate 2. A sample preparation cylinder 4 is engaged with the circular groove of the sample preparation base plate 2. Four sample preparation connecting posts 3 are provided on the sample preparation base plate 2 at equal intervals in a circular pattern on the outer side of the sample preparation cylinder 4. The outer side of the upper middle section of the sample preparation connecting post 3 is provided with a male thread 31. The sample preparation top plate 5 is a circular plate, and through holes 51 are provided on the sample preparation top plate 5 at positions corresponding to the four sample preparation connecting posts 3. The top end of the sample preparation connecting post 3 is sleeved in the through hole 51, and... The top of the sample preparation connecting column 3 is threaded with a locking nut 32. The locking nut 32 has a female thread. The locking nut 32 is used in conjunction with the male thread 31 of the sample preparation connecting column 3. The sample preparation connecting column 3 and the locking nut 32 are used to lock the sample preparation top plate 5 at the top of the sample preparation cylinder 4. This allows the sample preparation cylinder 4 to be stably placed between the sample preparation bottom plate 2 and the sample preparation top plate 5. The sample preparation of the sample 6 can be completed between the sample preparation bottom plate 2, the sample preparation cylinder 4 and the sample preparation top plate 5.

[0028] In order to facilitate the control of the size of the sample 6 and the subsequent sampling of the sample 6, the length of the sample preparation connecting column 3 is greater than the height of the sample preparation cylinder 4, the outer diameter of the sample preparation cylinder 4 is smaller than the outer diameter of the sample preparation top plate 5, and the outer diameter of the sample preparation top plate 5 is smaller than the outer diameter of the sample preparation bottom plate 2.

[0029] The top plate 5 for sample preparation is provided with a vacuum port 52 in the middle, through which the vacuuming operation can be completed during the sample preparation process.

[0030] The sample preparation top plate 5 is also provided with multiple liquid injection ports 53, through which bacterial solution or reaction solution is injected into the sample preparation cylinder 4.

[0031] In summary, when using this method, first install the sample preparation base plate 2 inside the sample preparation cavity 1, then attach the bottom end of the sample preparation cylinder 4 to the circular slot of the sample preparation base plate 2, and then put the arsenic sandstone particles into the sample preparation cylinder 4. Stop putting the arsenic sandstone particles in when the height of the arsenic sandstone particles in the sample preparation cylinder 4 is between 3-5 cm and the top of the sample preparation cylinder 4.

[0032] Then, the top plate 5 is snapped onto the top of the sample preparation cylinder 4, and the top plate 5 is snapped onto the top of the sample preparation cylinder 4 by means of the sample preparation connecting column 3 and the locking nut 32, so that the sample preparation cylinder 4 is stably placed between the bottom plate 2 and the top plate 5.

[0033] Then, select the appropriate liquid injection port 53 according to the type and location of the bacterial solution and reaction solution, and connect the external bacterial solution or reaction solution pipe to the corresponding liquid injection port 53. Then, close all liquid injection ports 53 using the control valve. Then, use the vacuum interface 52 to connect the external vacuum equipment to remove the air from the sample preparation cylinder 4. After that, open the control valve of the liquid injection port 53 connected to the bacterial solution or reaction solution pipe, inject the bacterial solution and reaction solution into the sample preparation cylinder 4, and then place the mold in a temperature-controlled environment to maintain suitable temperature and humidity to promote the microbial reaction. After the reaction is completed, open the sample preparation top plate 5 and take out the sample preparation cylinder 4. Then, take out the sample 6 from the sample preparation cylinder 4 to complete the sample preparation process. It is convenient and practical.
