Energy recovery system for heating bath pretreatment of electroplating nickel production line

Abstract

The invention discloses an energy recovery system for heating bath pretreatment of an electroplating nickel production line. The energy recovery system comprises a base plate, a hot water tank, an airpump and a heat exchange cavity; the base plate is provided with the hot water tank and a thread support rod; an electric heating wire is embedded in the inner wall of the hot water tank; a drainagepipe is arranged on the right wall of the hot water tank; movable blocks are arranged at the outer periphery of the thread support rod; connecting rods are symmetrically welded on opposite inner sidesof the movable blocks; an upper cover is welded at the tail ends of the connecting rods; the upper end of the upper cover is connected with the air pump; an upper placing plate is arranged at the upper end of the thread support rod; a motor is connected to the left side of the upper end of the upper placing plate; the heat exchange cavity is welded at the upper end of the upper placing plate; a connecting hose is connected between the lower end of the heat exchange cavity and the air pump; a coiler, a straight pipe and a spiral pipe are arranged on the connecting hose in sequence; the lower end of the spiral pipe is connected with an exhaust pipe; and a liquid outlet pipe is connected to the lower part of the right wall of the heat exchange cavity. The energy recovery system can use the steam temperature for preheating water, and effectively uses machining afterheat to save more energy.

Description

technical field [0001] The invention relates to heat recovery equipment in electroplating nickel production, in particular to an energy recovery system for thermal bath pretreatment of a nickel electroplating production line. Background technique [0002] At present, it is necessary to carry out a pretreatment process on the workpiece before electroplating nickel, and then perform impact nickel nickel plating on the workpiece, and then perform bright nickel nickel plating on the workpiece after washing with water, and then perform post-processing on the workpiece. During the whole process, the workpiece needs to be cleaned in a hot water tank before the subsequent process can be carried out. Since the hot water tank is exposed to the air, the heat loss in it is very serious, which will cause a lot of waste of energy. conducive to the production of enterprises.

During the entire process, the workpiece needs to be cleaned in a hot water tank before the subsequent process can be carried out. Since the hot water tank is exposed to the air, the heat loss in it is very serious, which will cause a lot of waste of energy. Conducive to the production of enterprises

[0003] In the prior art, there are heatable and non-heatable hot water tanks, but what they have in common is the loss of a large amount of heat and the time it takes to heat the hot water. These two points are the key points that affect the production cost in this link.
