The invention relates to the technical field of dispensing machines, and discloses a PCB board dispensing machine, including a cabinet, a hinge block is fixedly installed on the front of the cabinet, and a cabinet door is fixedly installed on the back of the hinge block, and the cabinet door The front of the cabinet is fixedly installed with a pull ring, the top of the cabinet is fixedly installed with an electronic balance, the top of the electronic balance is movably installed with a glue mixing cup, and the top of the cabinet is fixedly installed with a baffle at the rear of the electronic balance. Positioning holes are provided on the top of the baffle. The PCB board dispensing machine drives the turntable to rotate through the output shaft, and the turntable drives the stirring rod to stir the colloid through the slider. The chute and the slider produce relative sliding during the rotation process to prevent the eddy current phenomenon caused by the concentric stirring of the stirring rod, thereby It makes the colloid stir more evenly, and at the same time, the protective cover and the baffle seal the glue mixing cup to prevent the colloid from splashing and external dust from contaminating the colloid, and achieve the effect of efficient dust prevention.

The invention discloses a pipeline configuration structure of a triple-inlet air cooler system for hydrogenation reaction effluents. The pipeline configuration structure is characterized in that an inlet header pipe is perpendicularly downwardly communicated with a middle point of a first pipeline, two ends of the inlet header pipe are respectively communicated with a second pipeline and a third pipeline, and a plane formed by the second pipeline and the third pipeline is perpendicular to a plane formed by the inlet header pipe and the first pipeline; the tail end of the second pipeline and the tail end of the third pipeline are perpendicularly communicated with a fourth pipeline, two ends and the center point of the fourth pipeline are respectively perpendicularly communicated with a fifth pipeline, a seventh pipeline and a sixth pipeline, a plane formed by the fifth pipeline, the seventh pipeline and the sixth pipeline is perpendicular to a plane formed by the first pipeline, the second pipeline and the third pipeline, and the fourth pipeline is quartered by three joints along the length direction of the fourth pipeline and the three joints are formed by the fourth pipeline jointed with the second pipeline, the third pipeline and the sixth pipeline respectively and the tail end of the fifth pipeline, the tail end of the sixth pipeline and the tail lend of the seventh pipeline are perpendicularly communicated with an air cooler header and quarter the air cooler header. The pipeline configuration structure has the advantages that phenomena of multi-phase flow erosion corrosion, deposition and blockage of ammonium salt and under-deposit corrosion due to uneven distribution of flow parameters of existing air cooler tube bundles can be reduced, unintended shutdown accidents are reduced, and the safe operation cycle of the air cooler system for the hydrogenation reaction effluents is prolonged.

The invention discloses a low-energy air purification system. The low-energy air purification system comprises an intake filtering unit, an air return channel, a first blade wheel, an air return filtering unit and electrostatic dust collection devices, wherein a first flow equalization device is transversely arranged at the lower end of the intake filtering unit; the air return channel is arranged in the indoor side wall; the first blade wheel is transversely arranged between the intake filtering unit and the first flow equalization device, a center rotary shaft of the first blade wheel penetrates an indoor ceiling upwards and is connected with a drive mechanism, and a bottom channel is transversely arranged at the indoor bottom; an intake opening of the air return filtering unit communicates with the indoor bottom space, and an air outlet of the air return filtering unit communicates with the bottom channel; and the electrostatic dust collection devices are arranged in the portion, on the two sides of the air return filtering unit, of the bottom channel, an inlet of each electrostatic dust collection device communicates with the bottom channel, and an outlet of each electrostatic dust collection device communicates with the bottom of the air return channel. The low-energy air purification system solves the technical problem that energy consumption is too high by means of an existing air purification system.
