Description

Sample washing equipment for micro-body archaeological extraction experiment

Technical Field

The utility model belongs to the technical field of the experimental facilities technique and specifically relates to a little ancient biology draws experiment with washing appearance equipment is related to.

Background

The extraction of the micro-body paleontological fossil is an important link for researching the micro-body paleontological fossil, and the experimental effect involved in the link directly influences the later stage paleontological identification result. The micro ancient biogenic fossil is the remains or traces of animals and plants in the geological history period like the macrochemical fossil, and is divided into one category independently because the individual is tiny, the diameter is generally less than 1mm, and the categories of the fossil are various, such as sporopollen, radioactive insects, tartar, coccid and the like. They are respectively presented in different rocks, and the reagents and experimental methods adopted for extracting the micro-body paleontological fossil from different rocks are different.

Mesogenic insects are commonly found in argillaceous rock systems or marl. Required for the conventional experiment: a laboratory with a water tank, protective articles such as rubber gloves and goggles required by the experiment, 2 surfaces of a stainless steel mesh screen with the diameter of 20cm, 200 meshes and 40 meshes respectively, 5% -15% hydrogen peroxide (the total amount is determined according to the number of samples, generally speaking, one sample needs 250ml), a plurality of 1000ml plastic beakers and a plurality of 50ml glass beakers.

The existing traditional experimental method is a pure manual method, and comprises the following experimental steps:

1. sample crushing: each rock sample is broken into small blocks with a hammer, the size of each rock sample is about 1cm multiplied by 1cm or smaller, 200g of small blocks are taken and respectively put into 1000ml of standard beakers, and the beakers are marked according to the sample numbers to distinguish the samples.

2. Soaking sample: hydrogen peroxide with the concentration of 10% is poured into each beaker with fine stones until the liquid surface submerges all the stones. Covering the cover and standing for 24-48 hours.

3. Washing a sample: the sample in the last step reacts with the hydrogen peroxide for a long time, most of the argillaceous stones are sludge-shaped, and a few unreacted stones are contained. The purpose of this step is to remove sludge and large particle rocks from the sample, and to retain small particles between 200 mesh and 40 mesh.

Firstly, the stainless steel mesh is superposed, a 40-mesh sieve is arranged above, a 200-mesh sieve is arranged below, and the outer rings of the stainless steel mesh and the 200-mesh sieve are provided with catching grooves which can be clamped up and down. Secondly, the stacked screens are placed in a water tank, and the water level of the water tank submerges the top of the first layer of screen but does not exceed the top of the second layer of screen. Thirdly, the 1000ml size beaker sludge sample is poured into a 40 mesh sieve and the sieve is covered. Fourthly, the two hands hold the mesh screens filled with the sludge-shaped samples tightly, shake up and down in the water tank, and take away the sludge by utilizing hydrodynamic flushing (the action needs to pay attention to the force and the water flow rate, the damage of the corpuscle paleontological fossils is easily caused by overlarge force, the general amplitude is controlled to be 3-5cm, and the frequency is about 80 times per minute. After a period of time of scouring, the water in the water tank becomes turbid, the turbid water is discharged, then clear water with the same volume is put in, and the mesh screen is continuously shaken to scour the silt quality until the water in the water tank is basically clear, which indicates that the silt quality is basically elutriated. Each sample typically took about 30 minutes for this step.

4. Collecting a sample: after the previous step of scouring and elutriating, the sludge is washed away, and large particles are left in a 40-mesh screen and can be discarded. The mesh screen of 200 meshes is used for storing small particles between 200 and 40 meshes, and the extracted coccid fossils are in the small particles. The granules in the 200 mesh sieve are slowly flushed into a beaker with the specification of 50ml by using clean water, and then the beaker is placed into a dryer to dry the granules. And (4) selecting the dried small particles under a microscope to select fossil particles.

The applicant has found that the prior art has at least the following technical problems:

1. generally speaking, the micro-body archaea extraction experiment has long working time in the step of sample washing, and the mesh screen is shaken manually for a long time, so that the physical supply is not good. (generally, 20 samples are made in a batch of experiments, and each sample needs to be manually elutriated for 30 minutes in a sample washing process)

2. The extraction experiment of the micro-body archaea is generally carried out in corrosive liquid such as acid liquor or alkali liquor, and the human hand can be hurt to the skin after being soaked in the liquid for a long time. (although rubber gloves can isolate liquids, shaking the screen for extended periods of time can cause liquid splashing)

3. On washing a kind step, because the long-time mesh screen that lasts shakes, the difference in can not cause shake frequency and dynamics because of the physical power problem, because the corpuscle ancient biology fossil generally is comparatively weak little casing and the fossil that has fragile branch, the change of dynamics can lead to the fact the damage to it, and to the new hand, the fossil spoilage that draws is higher, is unfavorable for the research on next step. And long training time is required to become a skilled old hand.
