The invention discloses an optical cable splice box with dust removal and heat dissipation functions. The optical cable splice box comprises a lower box body, a side turnover door and an upper box body, wherein the upper box body is welded to the upper part of the lower box body, and the side turnover door is rotatably connected to the front face of the upper box body through hinges. According tothe optical cable splice box, an air intake elbow pipe is driven to align with the wind intake direction through contacting of a paddle board and an external air flow, and the external air flow is ledinto the upper box body for heat dissipation, so that the use frequency of a draught fan is lowered, the service life of the draught fan is prolonged, and energy is saved. A rubber ball is driven toperiodically impact by a reverse air flow generated by driving the draught fan, and a first airbag pad and a second airbag pad have elasticity, so that dust is accelerated to be dropped from the upperpart of a purification mesh enclosure and the dust removal performance of the optical cable splice box is improved, an insulating cover is connected to the position, corresponding to window-shades, of the inner wall of a lower turnover door, and when a mosquito is killed, the body of the mosquito stuck in a high-voltage shock net can be discharged outward through conduction of the insulating cover to ensure the effects of mosquito prevention and exhausting.

The invention provides a device for classifying and preserving progesterone raw materials. The device for classifying and preserving progesterone raw materials includes a base; two storage tanks, both of which are arranged on the top of the base; and two feed pipes, which are respectively arranged at two. the top of each of the storage tanks; two discharge pipes, which are respectively arranged at the bottom of the two storage tanks; four guide wheels, all of which are arranged at the bottom of the two storage tanks At the bottom of the base, the four guide wheels are distributed in a rectangular array; the four fixing mechanisms are arranged at the bottom of the base, and the four fixing mechanisms are respectively connected with the four guide wheels. Correspondingly; two side plates, both of which are fixedly installed on the top of the base. The progesterone raw material classification and storage device provided by the invention has the advantages of convenient movement, relatively stable fixation, and the ability to discharge excess gas in the tank.
