The invention discloses crushing and mixing equipment for cosmetic production. The crushing and mixing equipment comprises an upper box body and a lower box body; the upper box body is located at thetop end of the lower box body; one side of the top end of the upper box body is provided with a feed port; a motor II is arranged in the middle of the top end of the upper box body; a rotating shaft II is arranged at the position, extending into the upper box body, of the bottom end of the motor II; a crushing column is arranged on the rotating shaft II; a filter cylinder is arranged inside the top end of the upper box body; the rotating shaft II is located in the filter cylinder; a feeding pipeline is arranged on one side of the filter cylinder; the top end of the feeding pipeline is connected with the feed port; a plurality of upper closing plates are arranged at the outer side edge of the bottom end of the upper box body; lower closing plates matched with the upper closing plates are arranged at the positions, located at the outer side edge of the top end of the lower box body, of the lower part of the lower box body; a plurality of hydraulic rods are arranged at the corners of thebottom end of the lower box body; springs are arranged on the hydraulic rods; bases are arranged at the bottom ends of the hydraulic rods; a motor I is arranged in the middle of the bottom end of thelower box body; a rotating shaft I is arranged at the position, extending into the lower box body, of the top end of the motor I; and mixing blades are arranged on the rotating shaft I.

The invention relates to an undercurrent external heat exchanger of a circulating fluidized bed, which comprises a feeding vertical pipe, a feeding chamber, a heat exchanging chamber, a coiled pipe heating surface arranged in the heat exchanging chamber, an inlet header, an outlet header, a first partition wall, a second partition wall, an overflow chamber, an ash returning pipe, and an undercurrent hole; wherein a row of undercurrent holes are arranged at the lower part of the first partition wall between the feeding chamber and the heat exchanging chamber so that both of the upper part and the lower part of the heat exchanging chamber are supplemented by high temperature circulating ash, thus improving the flowing and heat exchanging condition of a dead zone in the heat exchanging chamber; and the upper rand lower temperature gradient of the heating exchanging chamber decreases, which is beneficial to the mixing of the circulating ash; the integral heat exchanging performance of theheat exchanging chamber is enhanced; a walling is arranged next to a side wall; the bend part of the coiled pipe heating surface is buried in the waling, not only bears the support and fixes the coiled pipe and heat exchanger, reduces the vibration of the heat exchanger, but also protects the bend of the heat exchanging surface of the coiled pipe not to be corroded by the circulating ash. The technical solution of the invention is easily realized and beneficial to solve the problems of heat transmission, vibration and abrasion of the external heat exchanger.

The invention discloses a motor. The motor comprises a shell, a stator and a rotor, wherein the stator is arranged in the shell; the rotor is arranged in shell; a base is arranged below the shell; thebase comprises a buffering device and a brake device; the brake device comprises a control component and a slide component; the buffering device comprises a support sleeve and a support convex column; the support sleeve sleeves the support convex column; and the support sleeve can sleeve the support convex column, and play a role in supporting the motor. When the motor works, strong vibration isgenerated, the vibration is transferred to the base in order to drive the whole motor to vibrate, and the support sleeve and the support convex column on the base cooperate with each other to relievethe vibration of the motor and play a role in buffering, so that the working stability of the motor is improved.
