The utility model relates to the technical field of drying equipment, in particular to a high-purity antimony particle drying device which comprises a drying box body, a filter and an air return cavity, one side of the drying box body is connected with the filter, the other side of the drying box body is connected with the air return cavity, an air inlet is formed in the side, connected with the filter, of the drying box body, and an air outlet is formed in the upper portion of the side, connected with the air return cavity, of the drying box body. The upper part of the air return cavity is provided with an air return port and connected to an air return pipeline; a heating cavity is formed in one side of an air inlet of the filter, heating pipes protected by non-metal materials are uniformly arranged in the heating cavity, and temperature measuring points are arranged in the heating cavity; a drying machine is mounted outside the drying box body, is connected with the air return pipeline and is provided with a water outlet; the heating cavity supplies air through an air feeder. According to the high-purity antimony particle drying device, by reasonably designing the number proportion of the air inlet holes and the air outlet holes, a multi-layer tray placing structure and the layout of the heating pipes, the flowing path and heat distribution of hot air flow in the drying box body are optimized.

The utility model discloses a raw material drying device for processing a preservative film, and relates to the technical field of preservative film processing, the raw material drying device comprises a device main body, one side of the top of the device main body is respectively provided with a charging port and a first motor, the top of the charging port is communicated with a storage bin, and a discharging roller is arranged in the charging port through a rotating shaft; when the discharging device works, the first motor drives the rotating shaft and the discharging roller to stably rotate through a transmission structure composed of the driving synchronous belt, the synchronous wheel and the driven synchronous belt, so that the discharging groove periodically passes through a discharging opening of a storage bin at the set frequency (such as 20 revolutions per minute), and when the discharging groove containing particles rotates downwards, the discharging groove is driven to rotate downwards. The particles quantitatively fall into the groove and are discharged along with rotation of the discharging roller, intermittent uniform discharging is achieved, the phenomenon that the particles are too thick due to uneven manual discharging can be avoided, local'drying blind areas' are eliminated, and the later drying effect is improved.

The utility model discloses an accurate powder metering device for a concrete mixing plant, relates to the technical field of concrete mixing plants, and aims to solve the problems that the existing volumetric and gravity type powder metering is low in accuracy, easy to be influenced by impact, incapable of accurately supplementing materials and the like, the device comprises a mounting frame, and a weighing bin, a feeding cylinder and a driving motor are sequentially arranged on the mounting frame; the weighing bin is provided with a weighing sensor and a discharge valve; the feeding cylinder is connected with the weighing bin through flexible connection, the top of the feeding cylinder is in threaded connection with a transmission rod, and the bottom of the transmission rod is provided with a partition plate and rotationally connected with a blocking disc which is provided with a distribution box, an upper opening and a lower opening. The driving motor drives the transmission rod to rotate, small-dose accurate material supplementation is achieved through cooperation of the material distribution box and the partition plate, the vibration influence is reduced through flexible connection, and the isolation hood prevents powder from influencing transmission. The device can accurately meter various powder materials, and is reasonable in structure, easy and convenient to operate and suitable for various concrete mixing plants.

The invention discloses a resistance welding bridge optimization method for industrial graphic computer-aided manufacturing, which comprises the following steps of: reading data of a resistance welding layer, and traversing to find a group of windows, which do not meet requirements, of a resistance welding bridge; judging according to the type of the solder resist windowing, wherein the solder resist windowing is divided into three types: two solder resist windowing in one group have BGA (Ball Grid Array) or SMD (Surface Mount Device) attributes; one solder resist window in one group has a BGA or SMD attribute, and the other solder resist window in one group has a non-BGA or SMD attribute; the two resistance welding windows in one group do not have the BGA or SMD attribute, the resistance welding windows are cut down in an equal proportion mode, and the steps are repeated till all resistance welding windows are processed, and according to the importance BGA < gt > of the bonding pad, the resistance welding windows can be processed according to the BGA < gt > of the bonding pad; m < M > D < gt >; pTHgt, PTHgt; vIAgt, VIAgt; the NPTH sequence is effectively adjusted to meet the requirements of the production process, and the reject ratio caused by the solder bridge problem can be effectively improved.
