The invention provides a resin insulation dry type transformer with a three-dimensional reel iron core. The dry type transformer comprises a transformer body, the transformer body comprises a three-dimensional reel iron core, the three-dimensional reel iron core comprises single frames of a rounded rectangle structure, the three single frames are arrayed and spliced into a three-dimensional equilateral triangle body, the splicing portion of every two adjacent single frames is wound and connected through a coil to form three windings, and each winding is cured and formed by integrally pouring a curing agent; the upper end and the lower end of the three-dimensional reel iron core are clamped by an upper clamping part and a lower clamping part respectively, the three-dimensional reel iron core is fixed to a transformer base, an upper blowing cooling fan is arranged in the lower clamping part, the upper surface of the lower clamping part is hollow, and an air port of the upper blowing cooling fan faces upward and blows air in the axis direction of the windings. According to the resin insulation dry type transformer with the three-dimensional reel iron core, the upper blowing fan is located below the windings and blows air from the underneath of the windings in the axis direction of the windings to cool the windings in a forced mode, so that heat dissipation of the transformer is uniform, the phenomenon of nest wind is prevented, and the service life of the transformer is prolonged.

The invention belongs to the technical field of environmental engineering, in particular to a sludge dehydrating and drying process method and a device. The technical essential points of the invention are that: firstly, adding one or several of fly ash, fine manganese slag, calcined lime, ferric chloride solution and aluminum sulfate solution into sludge and dehydrating and conditioning the sludge; secondly, feeding the sludge into a pre-drying area and simultaneously adding a certain amount of calcined lime, potassium permanganate and finished product of dry sludge and uniformly mixing; feeding the sludge treated in the pre-drying area into a hollow paddle spiral indirect dryer; returning one part of finished product of dry sludge to the pre-drying area and carrying out drier back-mixingwith wet sludge; supplying saturated heated steam to a drier by an electric boiler; and introducing steam tail gas from the drier to the pre-drying area for heating the wet sludge. The device is automatically controlled by a control center through a control bus. The process has the advantages of energy saving, environmental protection and high efficiency.

The invention discloses an industrial park environmental protection service platform based on big data, including an enterprise server cluster, an industrial park server cluster, and a data server cluster; the enterprise server cluster collects enterprise data, the industrial park server cluster collects all industrial park data, and the data server cluster Processing and interacting with users can monitor the data of the industrial park and various enterprises in real time, eliminate the existence of companies that do not deserve their names, and provide a guarantee for the healthy development of the industrial park.

The invention relates to the field of sports equipment maintenance, in particular to a sports equipment cleaning device. The technical problem to be solved by the present invention is to provide a sports equipment cleaning device. A cleaning device for sports equipment, comprising a workbench, a cycle flip feeding mechanism, a cleaning positioning mechanism, a positioning rotation mechanism, a gap edge cleaning mechanism, a display controller, a basketball and an automatic lifting baffle; Mechanisms are connected; the middle front inside the workbench is connected with the cleaning positioning mechanism; the front middle inside the workbench is connected with the positioning and rotating mechanism. The invention realizes the automatic adjustment of the position of the basketball, and can adjust the basketball according to the texture of the basketball. It can simultaneously clean the elliptical gap, the straight gap and the angled sideline of the basketball, and can automatically clean the basketball in batches, preventing the existence of germs in the gap. , the possibility of infecting players.

The invention relates to the technical field of nanomaterial grinding, in particular to a nonporous nanomaterial grinding method, comprising the following steps: preparing dry nanomaterials; putting the dry nanomaterials into a grinding tank for grinding, and grinding the grinding tank during the grinding process. Carry out vacuuming; during the vacuum grinding process, put the grinding fluid into the grinding tank to mix and grind; grind the nanomaterials in the grinding tank with ceramic grinding rollers, the temperature during the grinding process is controlled at 30-90 °C, and the grinding time is 0.3-5 Hours, the grinding roller rotating speed is 500~3000RPM; The present invention realizes the grinding of non-porous material, adds grinding liquid in grinding process and carries out mixed grinding, promptly adopts wet grinding, and nano material is liquid nano material after grinding, this process The method has a good grinding effect on the material, a good forming effect on the material, and a high grinding precision.
