The invention discloses a guiding belt deviation rectifying device of a circular screen printer. The guiding belt deviation rectifying device comprises a guiding belt, a tension roller, a driving roller, a deviation rectifying motor, a camera and a controller. The guiding belt is arranged on the tension roller and the driving roller in a tensioning mode and carries out transmission through the driving roller. The guiding belt is provided with three continuous color blocks which are arranged in the axial direction of the driving roller. The camera collects images of the color blocks in real time, and the images collected in real time are transmitted to the controller. The controller compares the images collected in real time with standard images, whether the guiding belt deviates is determined, a control order is obtained, and the control order is sent to the deviation rectifying motor. The deviation rectifying motor carries out deviation rectifying on the driving roller according to the control order. According to the guiding belt deviation rectifying device of the circular screen printer, the images of the three color blocks are collected, whether the guiding belt deviates can be easily know by comparing, meanwhile, colors obtained by collecting are different, the direction of deviating can be easily known by comparing, and detecting of guiding belt deviation is very easy.

The invention provides a preparation method of a high-solid content catalytic cracking catalyst. The method comprises the following steps: (1) mixing pseudo-boehmite, a binder and water and stirring evenly; (2) adding a soluble salt of which an anion is selected from Cl<->, NO3<->, ClO4<->, CH3COO<-> or HCOO<->, stirring evenly and standing; (3) adding an acid to the slurry obtained in the step (2), stirring and adding the acid in multiple times; and (4) adding a molecular sieve and the clay to the slurry obtained in the step (3), pulping and mixing evenly to prepare catalyst slurry, carrying out spray drying, solidification roasting, water adding and stirring, filtering and drying to prepare the high-solid content FCC catalyst. In the process of preparing the high-solid content catalyst by adopting the preparation method, the peptization speed is controllable and the mobility of the slurry is good; and heating and warming are not needed in the peptization process and a hydrochloric acid is replaced with other acids in the acidifying peptization process, so that the damage of a hydrochloric acid gas to the molecular sieve in the catalyst roasting process is avoided and the activity of the catalyst is improved.

The invention relates to a cooling device of an alumina decomposition pond, which comprises a decomposition pond and a stirrer arranged in the decomposition pond. The cooling device is characterized in that a heat pipe is arranged at the top of the decomposition pond and extends into the decomposition pond through a hole reserved on a top plate of the decomposition pond, wherein a heated section L of the heat pipe is inserted into fluid of the decomposition pond for absorbing heat, and the heat is continuously conducted into a cooling section M through a working medium in the heat pipe; a spiral cooling water guide channel is welded between an external sleeve of the cooling section of the heat pipe and the heat pipe, circular cooling water enters the spiral cooling water guide channel through the cooling section and flows out from the top of the external sleeve of the heat pipe through the guide channel for carrying out heat exchange, thereby the aim of fluid cooling in the decomposition pond is achieved. The invention is convenient to install and reliable in operation, has no power consumption during the operation of the heat pipe, no material plugging and has long service life; the maintenance and the replacement are convenient as the single heat pipe works independently, and the maintenance off production is unnecessary.

The invention discloses a multi-RAC cluster system and a data access method and device. The data access method comprises the following steps: determining available data sources according to the data source configuration information of a plurality of RAC clusters; choosing the first data source as a target data source from the available data sources according to a routing policy; according to the target data source, operating a corresponding target database; and calling the target database according to the database operating result or re-choosing the second data source as the target data source. By the multi-RAC cluster system and the data access method and device, new RAC clusters can be flexibly and dynamically added, and halt and maintenance are not required; transparency switching between failed RAC clusters and normal RAC clusters can be realized, the switching time is short, and TPS shaking or failed businesses hardly exists; and the RAC clusters are in equivalent relationship, when in downtime of any one RAC cluster, automatic migration of businesses (such as transaction) can be realized and service to the outside is not affected.

The invention is an identification method of geometric parameters of an industrial robot based on a transformation matrix error model, wherein the structure of the industrial robot includes a robot control cabinet, an industrial robot, an intelligent industrial camera, a camera mounting frame, a control signal communication cable and a transmission signal communication cable. The geometric parameter identification method of industrial robots first establishes the transformation matrix error model of industrial robots, and then obtains the nominal transformation matrix of the end pose of the industrial robot and the actual transformation matrix of the end pose of the industrial robot. Finally, the nominal transformation matrix and the actual transformation matrix The matrix is ​​brought into the transformation matrix error model to obtain the geometric parameter error, and the geometric parameter error is input into the robot control cabinet to adjust the positioning accuracy of the end of the industrial robot. This method does not require expensive external measuring equipment and does not require additional calibration, and can be used to improve the efficiency, production capacity and automation of industrial production lines.

The invention discloses a sorting device for logistics transportation for responding to emergencies, comprising a main conveyor belt on which a packing box position correcting mechanism is arranged, and the packing box position correcting mechanism comprises the following steps in the order of conveying. The first position visual identification mechanism, the first logistics packaging box flanging mechanism, the second position visual identification mechanism and the second logistics packaging box flanging mechanism are provided, and one side of the output end of the main conveyor belt is provided with a logistics label. In the visual inspection mechanism for scanning and identification, the end of the main conveyor belt is provided with a balance wheel logistics sorter, and the ends of the balance wheel logistics sorter are respectively provided with a plurality of connectors for docking the balance wheel logistics sorter. material conveyor belt. The invention ensures that no matter which side the material packing box is affixed with the logistics label, after being corrected by the packing box position correction mechanism, it can be identified by the visual inspection mechanism to read the logistics information on the logistics label, thereby improving the logistics sorting efficiency.
