The polar plate comprises a plate body with a flow field area, the flow field area is provided with a plurality of convex ribs which extend in the length direction of the polar plate and are distributed at intervals in the width direction of the polar plate, and a flow channel is formed between every two adjacent convex ribs. The runner comprises a first region and a second region which are communicated along the thickness direction of the polar plate, the first region is positioned on one side, close to the membrane electrode assembly, of the second region, and the sectional area of the first region is smaller than that of the second region. When the flow rate of the electrolyte is certain, the pressure intensity in the first area is greater than the pressure intensity in the second area, so that a flow pressure difference can be formed between the first area and the second area in the same flow channel, and gas positioned at the membrane electrode can flow towards the plate body along the membrane electrode assembly under the action of the flow pressure difference; and gas generated after electrolysis is prevented from being accumulated at the membrane electrode, so that the possibility of a gas aggregation effect at the membrane electrode is reduced, and the hydrogen production efficiency of the electrolytic cell is improved.

The utility model discloses a rice mould-proof device for rice processing, which comprises a bottom plate, the top of the bottom plate is fixedly connected with a support frame, the top of the support frame is fixedly connected with a rice bin, and the top of the bottom plate is fixedly connected with a fresh air assembly used for blowing air to cool the inside of the rice bin. The fresh air assembly comprises a draught fan fixedly connected with the top of the bottom plate, and an air inlet of the draught fan is communicated with a receiving sleeve. According to the rice mould-proof device for rice processing, the fresh air assembly is arranged, external air is sucked into the device, is simply filtered and then is directly fed into the rice bin, a plurality of same isolation plates are arranged in the rice bin, air conveniently and directly enters the rice bin through air nozzles, rice is divided by the isolation plates, and even if the interior of the rice is accumulated and heated, the rice is prevented from being mildewed. Meanwhile, the mode that a high-power motor is adopted for stirring is avoided, and the storage cost is greatly reduced.

The utility model provides a coating mechanism and a coating device.The coating mechanism comprises a first die head, a second die head and a gasket; the second die head and the first die head are arranged at intervals; the gasket is clamped between the first die head and the second die head; the gasket and the first die head form a first discharging channel, and the first discharging channel is provided with a first discharging port; the gasket and the second die head form a second discharging channel, and the second discharging channel is provided with a second discharging port; the first end part of the gasket and the first end part of the first die head form a first discharge port, the first end part of the gasket and the second end part of the second die head form a second discharge port, and the first end part of the gasket protrudes out of the first end part of the first die head and the second end part of the second die head to form a protruding part. In this way, the protruding part can flatly remove a liquid film formed by the redundant second raw material flowing out of the second discharging port, and the first raw material flowing out of the first discharging port can well cover the surface of the second raw material on which the film is formed.

This application discloses a circularly tangential flat flame nozzle and its combined array structure, relating to the field of nozzle structures. It includes a nozzle body with an inlet end and an outlet end at both ends. Gaseous oxidant enters from the inlet end and exits from the outlet end. The inlet end has a circular cross-section, and the projection of the outlet end along the axis of the nozzle body's inlet end is elliptical. The outlet end is arc-shaped, with its axis perpendicular to the plane containing the major axis of the ellipse and the inlet end axis, and the arc axis intersects with the inlet end axis. This provides a sufficiently large scattering area, allowing the process gas and oxidant to mix thoroughly at the nozzle outlet, improving the combustion efficiency of the process gas, and forming a uniform temperature distribution in the reactor combustion chamber.

The application discloses a kind of anion-rich hydrogel electrolyte and its preparation method and application.The hydrogel electrolyte is composed of acrylamide monomer, polymerizable functional monomer containing anion group, natural polymer material, and zinc salt for building water-based metal battery.In the preparation process, the above-mentioned functional monomer, acrylamide and natural polymer material are dissolved in zinc salt solution and uniformly mixed, and then initiator and crosslinking agent are introduced, and thermal polymerization reaction is carried out at 40~80℃ to obtain anion-rich gel electrolyte.The gel electrolyte shows good thermal stability, ion conductivity and cycle performance in various water-based metal batteries, providing a new electrolyte design strategy for high-performance water-based metal batteries.
