The invention provides a copper slag self-pulverization iron extraction method and application thereof.The copper slag self-pulverization iron extraction method comprises the steps that copper slag and a calcium oxide-based additive are mixed to obtain mixed copper slag, the calcium oxide-based additive comprises calcium oxide and / or a calcium oxide raw material, the calcium oxide raw material can generate calcium oxide through heating, and the calcium oxide raw material can generate calcium oxide through heating; the adding amount of the calcium oxide-based additive meets the condition that the total mass of the primary calcium oxide and / or the generated calcium oxide is 29%-47% of the mass of fayalite in the copper slag; after the mixed copper slag is heated to 1250-1700 DEG C, heat preservation is conducted for 30-120 min, and modified copper slag is obtained; slowly cooling the modified copper slag at a cooling rate of 0.25-1 DEG C / min to obtain self-pulverization copper slag; and magnetic separation is performed on the self-pulverization copper slag, magnetite is recycled, and the technical problems of tedious production line and high energy consumption caused by the fact that procedures such as crushing and ore grinding cannot be avoided in the common technology are ingeniously solved.

The present invention belongs to the field of blockchain technology, and provides a driver form rendering method and device applied to a blockchain management platform. By agreeing on a form protocol with a backend and a driver end, the driver end develops form definition data according to the form protocol, configures a request entry address and related parameters, obtains a request trigger instruction from a user end, triggers the request backend to obtain complete form definition data from the driver end, and dynamically fills in blockchain platform information, parses the form definition data to obtain form content for page display, thereby effectively solving the technical problem that the front end alone writes a form that cannot adapt to the technical requirements of the blockchain management platform form, avoids the lengthy front-end logic implementation code, and avoids repetitive labor caused by a large number of similar form pages, so as to achieve a close connection between the driver end and the form, and the driver function can be independently implemented without relying on the front-end project, providing "plug and play" and "pluggable" functions, and a technical effect of flexible driving.

The present invention relates to the technical field of control devices, and in particular to a control device for automatic distribution and delivery of bolts for grid frames, comprising: a bolt automatic delivery structure for delivering bolts to a data collector; a data collector for detecting bolt performance; a main control machine for establishing a database and selecting combinations with acceptable adaptability; a grabbing structure for grabbing and fixing; a detector for testing mechanical properties of pre-welded products and delivering the pre-welded products to a welder; a welder for welding the pre-welded products and detecting welding results and delivering them to a waste bin and a discharge bin according to the demerits. The problem of low yield and material waste in the prior art is overcome.

The utility model relates to the technical field of brake disc production, in particular to a pretreatment horizontal fluidization coating line which comprises a pretreatment chamber, a drying furnace and a spraying chamber and further comprises a butt joint lifting machine, a first conveying line, a first jacking transfer machine and an AGV trolley goods shelf. The output end of the drying furnace is connected with the input end of the spraying chamber through the first conveying line, the spraying chamber is arranged on one side of the pretreatment chamber in parallel, the first jacking transfer machine is arranged at the end, close to the drying furnace, of the first conveying line and connected with the output end of the drying furnace, and the AGV trolley goods shelf is arranged on one side of the butt joint elevator. Brake discs can be transferred; the device is simple in structural design, precise and short in production line and automatic in the whole process, and the production efficiency is remarkably improved.

The application relates to a fine SCR denitration catalyst system capable of being regenerated multiple times, which comprises: a replaceable catalyst module containing a regenerable low-temperature SCR denitration catalyst with a working temperature below 300 DEG C; a reactor for accommodating the catalyst module; and a spraying system for spraying a reducing agent into the reactor. The regenerable low-temperature SCR denitration catalyst comprises a carrier framework formed by thermoplastic plastic; and a low-temperature SCR denitration catalyst active component compounded in and supported by the carrier framework. The fine SCR denitration catalyst system is rapidly regenerated and recycled by replacing the deactivated catalyst module with a new catalyst module or a regenerated catalyst module. The regenerated catalyst module is obtained by remolding the regenerable low-temperature SCR denitration catalyst in the deactivated catalyst module after regeneration. The regenerable low-temperature SCR denitration catalyst can be regenerated by remolding the carrier framework of the thermoplastic plastic.
