Automatic sediment screening washer

Abstract

The invention discloses an automatic sediment screening washer and relates to a screening washing device which can screen fine particles in sediments by clean water. The automatic sediment screening washer is provided with a cleaning screen unit, a water supply pipe, a water discharge pipe, a negative-pressure waste liquid containing device, a power vibration device, a base and a control circuit. The upper ends of cleaning screens are hermetically connected with a transparent anti-splashing cover, the upper end of the transparent anti-splashing cover is connected with an outlet of the water supply pipe, outlets of the cleaning screens are connected with the water discharge pipe, and an outlet of the water discharge pipe is connected with an inlet of a negative-pressure waste liquid containing bottle. The negative-pressure waste liquid containing device comprises the negative-pressure waste liquid containing bottle, an air suction joint and an air suction pump. The power vibration device is provided with a fixing box, a fixing base holder, a motor, a centrifugal block and at least six compression springs. The cleaning screens are arranged in the fixing box, the motor is fixed on the fixing base holder, an output rotating shaft of the motor is connected with one end of the centrifugal block, the upper ends of the compression springs are connected with the fixing base holder, and the lower ends of the compression springs are connected with the base. The control circuit comprises a speed regulator and a power adapter. An output end of the speed regulator is connected with the motor, and an input end of the speed regulator is connected with the power adapter.

Description

technical field [0001] The invention relates to a sieving device for sifting out fine particles in sediments by using clear water, in particular to an automatic sediment sieve for sieving out fine particles in marine sediments, river and lake sediments and surface soil Scrubber. Background technique [0002] The analysis and research of microfossils in marine sediments will involve the removal of fine particles, because these fine particles that have not been removed will adhere to the surface or decoration of fossils, and the next step of identification statistics cannot be performed, so these fine particles are removed It is a very important step in microfossil analysis. However, the differential sedimentation method used in the traditional analysis method takes too much time to remove fine particles, and the efficiency is too low. Generally, it takes 48-72 hours for each sample (depending on the content of fine particles in the sample, more time-consuming). For each tre...

However, the differential sedimentation method used in the traditional analysis method takes too much time to remove fine particles, and the efficiency is too low. Generally, it takes 48-72 hours for each sample (depending on the content of fine particles in the sample, more time-consuming). Each treatment (15 samples per batch), on average, it takes about 5 hours for each sample to completely remove fine particles. This analysis method is not suitable for the analysis and processing of large batches of samples.

[0003] At present, the sieving method with high efficiency (removing fine particles with a silk sieve) is to sieve and wash samples manually, and each person only sieves one sample at a time. It is necessary to tap the outer wall of the filter sieve to prevent fine particles from accumulating on the sieve surface to block the sieve holes and make it impossible to clean the sample. In this way, it is necessary to keep tapping and shaking during the whole cleaning process to ensure that the sample particles are in a suspended state, but at the same time it also creates constant knocking noise

In addition, it generally takes 10-40 minutes to wash out a sample (depending on the content of fine particles in the sample, more time-consuming). Although the efficiency of this method is greatly improved compared with the traditional sedimentation method, but The disadvantage of this method is that each person can only process one sample at a time, and only 10-15 samples can be processed in one working day. If the continuous processing is very labor-intensive for the cleaning personnel, and the constant noise will make people Upset, harmful to physical and mental health
