A separator 1 for a nonaqueous electrolyte secondary battery, includes a resin-made substrate (2) and a porous heat resistance layer (4) disposed on the substrate. The porous heat resistance layer includes an inorganic filler (6) and hollow bodies (7). The hollow body includes a shell portion and a hollow portion. The shell portion is formed of an acryl resin. The hollow portion is formed inside the shell portion. An opening portion extending through the shell portion to spatially interconnect the hollow portion and the outside of the shell portion is formed in the shell portion.

The invention provides a waterproof circulation box. The waterproof circulation box comprises a box body, a first box cover and a second box cover, wherein an opening is formed in the upper portion of the box body, and the first box cover and the second box cover are connected to the two opposite side walls of the box body in a rotatable mode respectively. The first box cover and the second box cover are each provided with a plurality of convex teeth and a plurality of concave teeth in a staggered mode, and the convex teeth can be connected with the concave teeth in a matched and buckled mode when the box covers are closed. The lower surface of the first box cover and the lower surface of the second box cover are provided with a first convex strip and a second convex strip respectively. The upper ends of the outwards-protruding bent portions of the first convex strip or the second convex strip are closed, the lower ends of the outwards-protruding bent portions of the first convex strip or the second convex strip are opened, and the convex teeth are formed; the upper ends of the inwards-sunken bent portions of the first convex strip or the second convex strip are opened, the lower ends of the inwards-sunken bent portions of the first convex strip or the second convex strip are closed, and the concave teeth are formed. The opened lower ends of the convex teeth are downwards attached to the closed lower ends of the concave teeth in a buckled mode from the opened upper ends of the concave teeth. The opened lower ends of the convex teeth are in contact with the closed lower ends of the concave teeth in an attached mode, water on the upper surface of the box body can be prevented from entering the interior of the box body along the first joint position formed after the first box cover and the second box cover are buckled, and therefore the waterproof effect can be achieved.

Above, a handle is provided on the cup body, a crushing knife is arranged in the cup body, and the motor drives the crushing knife to rotate, wherein, the cup cover includes an annular upper bracket, an annular lower bracket and a glass cover, and the glass cover is arranged on the upper bracket Between the lower support and the center of the glass cover is provided with a feeding port. Visible functions can be realized by adopting the above solution.

The invention discloses a box column for a ship, and belongs to the technical field of ship parts. The box column for the ship comprises a support plate, first convex plates, first steel cylinders, first concave plates, a support bar, a steel inner barrel, a steel outer barrel, a tripod, a second convex plate, a second steel cylinder, a third steel cylinder, a second bolt, an arc-shaped tripod, a supporting plate, a first bolt, a side plate, a bracket and a bottom plate; the steel outer barrel is welded and mounted between the bottom plate and the support plate, the steel inner cylinder is arranged in the steel outer barrel, the first concave plates are welded to the upper and lower ends of the steel inner cylinder correspondingly, and the first steel cylinders are welded to the first concave plates; and the first concave plates enfold the first steel cylinders, the first convex plates are welded to the left and right sides of the first steel cylinders correspondingly, and the first convex plates are welded and mounted on the inner side wall of the steel outer barrel. The box column for the ship has the advantage of high structural strength.

The invention discloses a coal mine water underground purification treatment method which comprises the steps of carrying out precipitation treatment on coal mine water underground for solid-liquid separation and carrying out oil-water separation treatment so as to remove suspended matters and oil dirt in the coal mine water. The mine water enters a water pond to reach the bottom of the water pond through a water inlet pipe and then is discharged uniformly from a water distribution area, after solid-liquid separation and oil-water separation are carried out by a silt removal-oil removal device, suspended matters precipitate and then enter a silt discharge device, oil dirt is discharged through an oil collecting pipe and purified mine water is discharged through a water outlet pipe. According to the method, used equipment is simple in structure, low in cost and arranged underground, so that the defects of larger occupied area, environment pollution and the like of ground treatment are overcome; in addition, by adopting the method provided by the invention, the technical problem that an oil removal measure does not exist in the conventional mine water purification treatment is solved, the removal efficiency of suspended matters and oil dirt in the mine water is high, the oil removal effect is obvious and the purified water reaches reusing or drinking standards.
