Description
Technical Field
The specification relates to the technical field of organic carbon testing, in particular to a sample washing device for assisting in determining total organic carbon content in sedimentary rock.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Total Organic Carbon (TOC) refers to the sum of the carbon content associated with organic matter contained in sedimentary rock. The organic carbon content in the sedimentary rocks can reflect the abundance of organic matters in the sedimentary rocks, and the organic carbon content (TOC) of the sedimentary rocks is one of important indexes for evaluating whether the sedimentary rocks can be used as hydrocarbon source rocks in an oil and gas system.
At present, the determination of the total organic carbon in sedimentary rock needs to be carried out according to the regulation of the national standard GB/T19145-2003, and comprises the following steps: crushing, weighing, dissolving, washing, drying, measuring and shutting down. Wherein crushing refers to grinding the sedimentary rock sample. The sample weighing means that 0.01g to 1.00g of sample is weighed according to the type of the sample. Dissolving the sample refers to slowly adding excessive hydrochloric acid solution into a container containing the sample to perform reaction so as to remove inorganic carbon in the carbonate rock mineral. The sample washing refers to placing the acid-treated rock sample in a porcelain crucible on a filter, and washing the rock sample to be neutral by using distilled water or deionized water. And the sample drying refers to that the ceramic crucible filled with the washed neutral sample is put into a drying oven at the temperature of 60-80 ℃ and dried for standby.
In the sample washing process, the existing treatment mode is manual liquid adding (distilled water or deionized water) washing. However, the sample washing process takes a long time and reaches a plurality of washing times, so that the washed sample can meet the experimental requirements, for example, the washing time is 48 hours, and the washing time reaches 100 times. This results in too much manpower for manual washing, and in the washing process, it is easy to cause artificial sample loss (for example, excessive liquid is added, which results in overflow of sample powder), which affects the total organic carbon determination result.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Please refer to fig. 1. The embodiment of the specification provides a sample washing device for assisting in determining the content of total organic carbon in sedimentary rock, and the sample washing device can comprise a placing part 2, a liquid adding part and a liquid collecting part 4.
Wherein the placing section 2 is provided with a plurality of accommodating chambers 21 for placing the samples. The placing part 2 can move relative to the liquid adding part, so that the liquid adding part injects water into different accommodating cavities 21. A passage is provided between the accommodating chamber 21 and the liquid collecting portion 4, and the liquid in the accommodating chamber 21 can flow into the liquid collecting portion 4 through the passage.
The sample washing device provided by the embodiment of the specification can be used for a sample washing process for determining the total organic carbon content in sedimentary rock. This wash appearance device places portion 2, liquid feeding portion and liquid collecting portion 4 through setting up, will wait that the sample of washing places portion 2 in hold chamber 21, through liquid feeding portion to holding chamber 21 internal water injection, collects the liquid that oozes in holding chamber 21 through liquid collecting portion 4, enables to survey the washing appearance step in the total organic carbon content in the sedimentary rock and realizes the machine and wash the appearance to use manpower sparingly.
In the embodiment of the present specification, since the sample contains acidic substances, the sample is washed with water and then flows into the liquid collecting portion 4 downstream of the placing portion 2 together with water, and the liquid collecting portion 4 may be made of a corrosion-resistant material. The liquid collecting part 4 may include a liquid collecting chamber and a vacuum pump communicating with the liquid collecting chamber. The vacuum pump can be arranged outside the liquid collection cavity as long as the vacuum pump is communicated with the liquid collection cavity. The vacuum pump can take away a large amount of air in the liquid collecting cavity, so that the liquid collecting cavity is in a negative pressure state, liquid in the accommodating cavity 21 can flow to the liquid collecting cavity more quickly, and the cleaning time is saved.
In the embodiment of the present specification, the sample may be directly placed in the containing chamber 21, and the outer wall surface of the containing chamber 21 may be made of a material that can pass the liquid but cannot pass the sample particles, so that the liquid after washing the sample can seep out and flow into the collecting portion 4 through the channel.
In another embodiment, the sample washing device may further comprise a reaction vessel 1 disposed in the receiving chamber 21. The reaction vessel 1 is used for containing a sample. The reaction vessel 1 is at least partially made of finely divided quartz particles, i.e. of comparatively fine quartz particles, with a certain percolation function. So that the reaction vessel 1 can pass the liquid but cannot pass the sample particles, and the liquid after the sample washing can be made to seep out of the reaction vessel 1. The material that can pass through the liquid and cannot pass through the sample particles can be alumina, silica, etc. For example, the reaction vessel may be a crucible made of permeable silica.
In the embodiment of the present specification, since the sample contains an acidic substance, the placing portion 2 may be made of a corrosion-resistant material. The housing chamber 21 may have the same shape as the reaction vessel 1, and the outer wall surface of the reaction vessel 1 may be placed so as to be in contact with the inner wall surface of the housing chamber 21. The channel comprises a through hole which is arranged at the bottom of the accommodating cavity 21 by the placing part 2 and is communicated with the accommodating cavity 21 and the liquid collecting part. The through hole can discharge the liquid seeped out from the reaction vessel 1 into the liquid collecting cavity. A plurality of through holes can be arranged at the bottom of one accommodating cavity 21 to achieve better liquid drainage effect. In this embodiment, the accommodating chamber 21 itself can limit the position of the reaction vessel 1, so that the reaction vessel 1 can be stably placed.
Wherein, the number of the accommodating cavities 21 can be multiple, so that the flushing operation can be simultaneously carried out on multiple samples, and the working efficiency is improved.
In the embodiment of the present specification, the reaction vessel 1 may have an opening, a bottom wall opposite to the opening, and a side wall connecting the opening and the bottom wall. The bottom wall and the side walls may be made of a material that is permeable to liquid and not to sample particles. The reaction vessel 1 may be provided with a boss at a position outside the side wall near the opening. As shown in fig. 2, the placing part 2 may be provided with a groove 10 for fitting the boss. In this embodiment, the groove 10 is matched with the boss to limit the reaction vessel 1, so that the reaction vessel 1 is stably placed. In addition, the outer wall surface of the reaction vessel 1 is not in contact with the accommodating cavity 21, so that the reaction vessel 1 can better permeate out the internal liquid, the cleaning efficiency is improved, and the cleaning time is saved.
In this embodiment, the placing section 2 may include an upper surface and a side surface. The upper surface is provided with a groove 10 which is matched with the boss. The space enclosed by the upper surface and the side surface forms an accommodating cavity 21 for accommodating the reaction vessel 1 and a channel for the liquid in the reaction vessel 1 to flow into the liquid collecting part 4, and the side surface separates the side wall of the reaction vessel 1 from the external space, which is beneficial to preventing the liquid seeped out from the reaction vessel 1 from polluting the environment. The lower end of the side surface may be lower than the lowest point of the reaction vessel 1 placed in the accommodating chamber 21.
Specifically, when the reaction vessel 1 is placed in the accommodating cavity 21 of the placing part 2, the opening of the reaction vessel 1 may be slightly higher than the upper surface of the placing part 2, so as to facilitate the subsequent liquid adding operation on the reaction vessel 1.
In the present embodiment, the liquid adding portion is located upstream of the placing portion 2, and the liquid adding portion may include the liquid outlet end 3. The liquid outlet end 3 is used for injecting water into the reaction vessel 1 in the accommodating cavity 21. The liquid outlet 3 may be higher than the opening of the reaction vessel 1 or lower than the opening of the reaction vessel 1 when water is injected into the reaction vessel 1. Preferably, the liquid outlet end 3 is lower than the opening of the reaction vessel 1 when water is injected into the reaction vessel 1, so that the injected water can be prevented from splashing the sample out of the reaction vessel 1, thereby causing sample loss and influencing experiment precision.
Specifically, the liquid outlet end 3 has a first position at least partially located in the reaction vessel 1, and a second position not located in the reaction vessel 1. When the liquid outlet end 3 is positioned at the first position, the liquid outlet end 3 can inject water into the reaction vessel 1. When the liquid outlet end 3 is at the second position, the placing part 2 can move relative to the liquid outlet end 3 to perform the liquid adding operation on the next reaction vessel 1. Of course, in other embodiments, the liquid outlet end 3 may be kept stationary, and is higher than the opening of the reaction vessel 1 during liquid injection.
In the present embodiment, the placing portion 2 is moved at a predetermined cycle that is longer than the time during which the liquid in the accommodating chamber 21 seeps out. This is to ensure that when the same accommodating chamber 21 or reaction vessel 1 is filled with water next time, the liquid in the accommodating chamber 21 or reaction vessel 1 has completely seeped out, and a cleaning process is completed, so that a better cleaning effect can be obtained. It has been found from a number of experiments that it takes about 5-6 minutes for the liquid in the reaction vessel 1 to seep out completely. The predetermined period may be set to 10 minutes or adjusted according to actual conditions. This is not particularly limited in the present specification.
In the embodiment of the present specification, the placing part 2 may include a rotatable turntable, a motor for driving the turntable to rotate, and a rotating shaft 5 for transmission. The rotating shaft 5 is positioned at the center of the turntable, and the motor can drive the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the turntable to rotate. The plurality of accommodating cavities 21 are uniformly arranged on the circumference of the circular turntable. When the liquid outlet end 3 is positioned at the second position, the disc can rotate; after the liquid outlet end 3 is aligned with the opening of the reaction vessel 1, the rotating disc stops rotating, the liquid outlet end 3 is switched to the first position from the second position, and water is injected into the reaction vessel 1; after the water is filled, the liquid outlet end 3 is switched from the first position to the second position, and the turntable can continue to rotate, so that the opening of the next reaction vessel 1 is aligned with the liquid outlet end 3, and the same operation as described above is carried out.
Specifically, the predetermined period of the turntable (i.e., the time for one rotation) is longer than the time for which the liquid in the reaction vessel 1 oozes out. The predetermined period of the turntable can be set to 10 minutes or adjusted according to the actual situation. This is not particularly limited in the present specification.
Further, the liquid collecting part 4 and the rotating disc can be connected through a supporting shaft. The support shaft may be located at a center of rotation of the turntable, and the turntable may rotate relative to the fixed support shaft. The liquid collecting part 4 is detachably connected with the rotary disc, so that the sample washing device can be conveniently mounted and dismounted.
In the embodiment of the present specification, the liquid collecting part 4 may be a hollow annular disk body, and a motor may be provided at a central position of the liquid collecting part 4 and may be located right below the rotating shaft 5. The outer wall diameter of collection liquid portion 4 can be greater than the external diameter of carousel, and the outer wall peak of collection liquid portion 4 can be higher than the minimum of placing portion 2 to make the liquid that reaction vessel 1 flowed out can not drip and splash outside collection liquid portion 4 and the polluted environment.
Of course, in other embodiments, the movement mode of the placing part 2 may be a linear movement, and the shape of the placing part 2 may be a rectangular parallelepiped or other shapes. A plurality of the accommodation cavities 21 may be uniformly provided on the placing section 2 in the moving direction. After the last reaction vessel 1 of the placing part 2 is filled with water, the placing part 2 is moved to align the first reaction vessel 1 with the liquid adding part, and the next cleaning cycle is performed.
In the present embodiment, the liquid adding part may include a liquid outlet end 3, a water tank 6, a liquid feeding line 7 connecting the water tank 6 and the liquid outlet end 3, a power element 8 on the liquid feeding line 7, and a flow control element 9 on the liquid feeding line 7. Wherein the power element 8 is used for providing power for conveying the water in the water tank 6 to the liquid outlet end 3 through the liquid conveying pipeline 7. Which may be a water pump. The flow control element 9 is used for controlling the liquid outlet time and the liquid outlet amount of the liquid outlet end 3. Wherein the liquid outlet amount can be 2-17 ml. Specifically, the flow control element 9 is electrically connected with the power element 8, and can control the opening and closing of the power element 8, so as to control the liquid outlet time; and the flow control element 9 includes a flow meter capable of measuring the liquid amount, thereby achieving control of the liquid amount.
The flow control element 9 can control the liquid outlet time to be matched with the moving time of the placing part 2, so that the moving period of the placing part 2 is longer than the time for the liquid in the accommodating cavity 21 to seep out. The flow control element 9, the power element 8 and the motor can be matched with each other, the opening and closing of the power element 8 can determine the liquid outlet time, the running condition of the motor can determine the movement and the stop of the placing part 2 and the moving speed of the placing part 2, and the liquid outlet amount, the liquid outlet time, the moving speed of the placing part 2 and the moving period which are reasonable in calculation and design can enable the sample washing device to run smoothly.
Specifically, the water in the water tank 6 may be deionized water. Deionized water is a liquid that is nearly pure water and has little effect on the experiment. Different from deionized water, certain metal ions and soluble organic matters can be remained in the distilled water, and the experimental requirements can be met only by more than three times of distilled water, so that the water in the water tank 6 is preferably deionized water.
In a specific application scenario, the reaction vessel 1 containing the acid-treated sample is placed in the receiving cavity 21 of the placing part 2. The tank 6 is filled with deionized water and a flow control element 9 on the infusion line 7 adjusts the amount of water added to a predetermined amount. The movement switch of the placement unit 2 is turned on to start the movement of the placement unit 2. For example, when the placing section 2 includes a turntable, the motor switch is turned on to start the rotation of the turntable. When the reaction vessel 1 to be added with water is aligned with the liquid outlet end 3, the placing part 2 stops moving, the power element 8 provides power, and a predetermined amount of water is injected into the reaction vessel 1. After the water is filled, the movement of the placing part 2 is continued, and then the next reaction vessel 1 is filled with water. The liquid after the sample washing seeps out of the reaction vessel 1 and flows into the liquid collecting part 4. When the number of flushing times reaches the requirement, the flushing is stopped, the reaction vessel 1 is taken out, and the waste liquid in the liquid collecting part 4 is poured out.
The sample washing device provided by the embodiment of the specification has the following advantages:
1. the experimental time required by scientific research personnel is reduced, and the labor is saved.
2. Realize washing through the machine, quantitative water injection, the steady motion of washing process can be guaranteed to the portion of placing 2 uniform velocities. The problem of manual washing in-process, probably there is artificial overflow phenomenon to lead to the sample loss, influence experiment precision is solved.
3. The method has the advantages of realizing flushing more quickly, automatically adding liquid, and having simple process, and the sample washing is used as a ring in the experiment for measuring the total organic carbon content in the sedimentary rock, so the sample washing step is simplified, and the experiment for measuring the total organic carbon content in the sedimentary rock is also simplified.
