The invention relates to the fields of life science and medical research, and discloses a full-automatic immunochemical instrument and a use method thereof. According to the invention, the full-automatic immunochemical instrument can realize automatic liquid charging and waste liquid suction in the whole process. By means of changing the liquid without changing a vessel hole, damage or position shift to a tissue slice sample due to frequent movement of the sample can be avoided in an operation process. Also, experimenters can avoid suffer body injury caused by direct contact with toxic substances. By automatic instrument operation, the labor intensity is alleviated, the efficiency is improved, artificial error can be avoided, and automation and standardization can be realized. A liquid distribution and liquid discharge structure and a liquid pipeline can move up and down, can drop during liquid charging and liquid suction, and rise during reaction vessel change, so that the operation can be more convenient. The liquid distribution and liquid discharge structure and the liquid pipeline can move around, batch treatment can be carried out on a reaction vessel hole matrix, and the efficiency can be higher.

Disclosed is equipment for separating irregular powder from spherical metal powder. A powder feeding tank body and a material tank body are arranged in a U-shaped tank. The material tank body is connected with a collector in the U-shaped tank. A net is arranged in the collector. The right end of the collector communicates with a powder blowing pipeline. The powder blowing pipeline is connected with an air duct. A net is arranged in the interior, on the right side of the U-shaped tank, of the powder blowing pipeline. The powder feeding tank is connected with the powder blowing pipeline. A draught fan is arranged in the powder blowing pipeline. A hinge valve is connected in the connecting position of the powder blowing pipeline and the air duct. A draught fan is arranged in the air duct. The air duct communicates with a top pipe opening of the collector. A separation method comprises the following steps that (1), screen nets are arranged, and the powder is located between the air duct screen net and the screen net at the bottom of the powder blowing pipeline; (2), samples enter from the powder feeding tank to the bottom of the powder blowing pipeline; (3), the draught fans are adjusted, and powder particles are layered in the powder blowing pipeline; (4), suction force of the collector is controlled by the hinge valve; and (5), after separating, the uniform and fine spherical metal powder is obtained in the material tank. The removal rate of sample separation at a time can reach 70%, and the irregular powder can be effectively separated from the spherical metal powder.

The invention belongs to the technical field of preparation of specialty paper in the paper-making industry and discloses a plant fiber and PHA (polyhydroxyalkanoate) composite oil-absorbing sheet and a preparation method thereof. The preparation method comprises steps as follows: (1) water is added to plant fibers for defibering and dispersion, the mass concentration of the plant fibers is controlled to range from 1% to 3%, and a defibered plant fiber suspension is obtained; (2) an aid, filler and PHA are sequentially added to the defibered plant fiber suspension and evenly mixed, paper is made with pulp and dried, and the plant fiber and PHA composite oil-absorbing sheet is obtained. The biocompatible and environment-friendly PHA is composited with the natural plant fibers, the cost is saved, and the obtained oil-absorbing sheet has good effects of oil absorption, water absorption avoidance, softness and degradability and has the bright application prospect.

A suction system comprising a suction pump (1) having at least one suction connection (2,2',2'') and a delivery connection (3), a receiving reservoir (4) connected to the delivery connection (3), connecting pipings from a suction connection (2,2') to a first space (7) from which a first fluid (8) should be sucked, and connecting pipings from the delivery connection (3) to the receiving reservoir (4), characterized in that the system further comprises a connecting piping (14,15,16) extending from a second space (10), from which a second fluid (11) should be sucked, to at least one suction connection (2,2',2'') of the pump (1), and comprises a device (12) disposed for causing an intermittent operation of the second fluid suction by the pump (1), responsive to the level reached by the second fluid (11) in the second space (10). Preferably, the pump (1) is a vacuum pump, the first fluid (8) is air, the first space (7) is a depressurized reservoir, the second fluid (11) is oil and the second space (10) is a space wherein oil (11) has a tendency to accumulate. The system is especially, but not exclusively, intended for automotive applications.
