The invention relates to a nickel sulfate evaporative crystallization process which comprises the following steps: S1, fresh steam supplies heat to a heat exchanger group, a first evaporation and concentration device and a second evaporation and concentration device; S2, a material enters the heat exchanger group to be pre-heated, then enters the first evaporation and concentration deice after being preheated, and when the material reaches an expected concentration in a gas-liquid separator, the material enters the second evaporation and concentration device to be further evaporated and concentrated; and S3, the material meeting the expected concentration value in the second evaporation and concentration device is discharged from a discharge port and enters a cooling kettle to be cooled, then enters a centrifugal machine to be separated and crystallized, and finally, a product is discharged from the centrifugal machine, and the separated mother liquor is stored in a mother liquor tank. The nickel sulfate evaporative crystallization process provided by the invention is stable and reliable, energy-saving and emission-reducing, small in occupied area and low in cost.

The invention discloses full-automatic vertical type combining and conveying equipment for plates, bowls and cups and an application method of full-automatic vertical type combining and conveying equipment. The full-automatic vertical type combining and conveying equipment comprises a plurality of conveying lines for conveying the plates, the bowls and the cups, wherein the conveying lines are combined into one conveying line at the tail end of one of the conveying lines. The full-automatic vertical type combining and conveying equipment has the advantages that the defect that bone plates, soup bowls, rice bowls, tea cups, water cups, spoons and dip bowls are combined by manually-operated combining and packaging equipment in the prior art is overcome, and the advanced and efficient production line combining and conveying equipment can integrally combine the bone plates, soup bowls, rice bowls, tea cups, water cups, spoons and dip bowls on the same operation platform during high-speed conveying.

The invention discloses a BT knife handle high-speed cutting mechanism and a use method and belongs to the technical field of numerically-controlled machine tool cutting machining. The BT knife handle high-speed cutting mechanism comprises a BT knife handle, a main shaft, a knife pulling mechanism, a pop-rivet and a cushion cover, wherein the end face of the non tool installation end of the BT knife handle is a knife handle rear end face, a circular cone frustum is arranged on the center position of the knife handle rear end face, the pop-rivet is installed on the center position of the end face of the circular cone frustum, the main shaft is a hollow shaft, the end face of the end, close to the rear end face of the knife handle, of the main shaft is a main shaft front end face, a taper hole is formed in the center portion of the main shaft front end face, the shape of the taper hole is matched with that of the circular cone frustum, the circular cone frustum is installed in the taper hole, the cushion cover is arranged between the knife handle rear end face and the main shaft front end face, the knife pulling mechanism is installed in a main shaft center cavity, and the knife pulling mechanism is connected with the pop-rivet in a clamped mode. By means of the BT knife handle high-speed cutting mechanism and the use method, the high-speed cutting of the BT knife handle is achieved, the contact rigidity and the repeated positioning accuracy of the BT knife handle are high, the high-speed cutting machining precision and the efficiency are high, the service lives of a tool and a machine tool are prolonged, and the BT knife handle can replace an HSK knife handle to be used.
