The invention provides a data processing method and a commodity selling device in one embodiment and aims at effectively solving the problems of heavy logistical waste and low cost performance due to that products only can be delivered to consumers after passing the commercial agents and distributors of multiple levels in the prior art. The data processing method in the embodiment is applied to the commodity selling device; an authorized seller and products allowed to be sold by the authorized seller as well as a supporting document certificating direct selling of the products are pre-stored in the commodity selling device; the method comprises the following steps: the commodity selling device pushes a product to a consumer; a transaction request submitted by the consumer is obtained; the supporting document is pushed to the consumer; the transaction request submitted by the consumer is received and processed, and after successful transaction processing, an instruction of directly delivering the product requested in the transaction to the consumer from the authorized seller directly is sent out. The data processing method is ingenious in design, the logistical cost of the products is remarkably reduced and the cost performance of product sales is improved; the data processing method conforms to practical requirements and is easy to popularize and utilize.

The invention discloses a stirrer for realizing desulfurization by using mechanical stirring. The stirrer comprises a stirring shaft and a connecting flange, wherein the connecting flange is arranged at the upper portion of the stirring shaft; stirring blades and a stabilizer are sequentially arranged at the lower end of the stirring shaft; each of the stirring shaft, the stirring blades and the inner layer of the stabilizer is a hollow metal pipe core; the top of each hollow metal pipe core is connected with the connecting flange; a metal blocking head is arranged on the inner wall of the lower end of the hollow metal pipe core; an air cooling pipe is inserted into each hollow metal pipe core; the top end of each air cooling pipe is connected with the connecting flange; the pipe orifice at the lower end of each air cooling pipe forms an air outlet with the corresponding metal blocking head. The stirrer disclosed by the invention has the advantages of reducing the intensity of rotating vortex of liquid iron below the bottom center of the stirrer, delaying the damage progress of the stirrer, improving the comprehensive application performances of the stirrer, effectively relieving the shortcoming of short long service life of a large stirrer and realizing the comprehensive aims of prolonging the service life of the stirrer, reducing the consumption of the stirrer, improving the economical efficiency and the direct-selling property of a large liquid iron KR stirring desulfurization technology and the like.
