Abstract
The utility model relates to a vertical water circulation device of a vacuum water quenching furnace and belongs to the technical field of a vertical water circulation device of a vacuum water quenching furnace. The vertical water circulation device of the vacuum water quenching furnace is characterized by comprising a water pipe, wherein the upper and lower ends of the water pipe are stretched into a furnace body, jet flow nozzles communicated with the water pipe are arranged at the pipe wall above the water pipe, the number of the jet flow nozzles is corresponding to the number of layers of charging baskets in the furnace body, the nozzles of the jet flow nozzles are aligned to 1/3 to 2/3 positions of the axle wires of the charging baskets and the side wall of a cold chamber, and a water pump is installed on the water pipe. The vertical water circulation device provided by the utility model is added with a side face circulation system to overcome the defect of insufficient up and down circulation capability in circular cooling of equipment and improve the circulation capability, and the charge batch of each layer can be increased, so that the charge batch can be improved by more than 3-4 times, and the mechanical property fluctuation caused by unsmooth workpiece cooling is solved, and the production efficiency and the product quality stability are improved.
Description
Technical field
The utility model relates to a kind of vertical vacuum water quenching oven water circle device, belongs to vertical vacuum water quenching oven water circle device technical field of structures.
Background technology
Patent name: the vertical vacuum water quenching oven, application number: 201010526509.1, open date: 2011.02.09; The vertical vacuum water stove cooling work-piece cools of this patent adopts circulation device up and down, limited by structure space, and circulatory mediator can only make progress in the charging basket side and flow; Shown in accompanying drawing 1, quenchant cycling use of water pump is extracted heat-eliminating medium out above quenching tank, below quenching tank, sprays; The formation quenchant flows, because workpiece layering shove charge has stopped quenchant moving up and down around workpiece, quenchant forms circulation from the charging basket side; Thereby cause the heat-eliminating medium above the workpiece mobile not smooth, can't form good heat exchange, the work-piece cools speed of different sites differs bigger; Caused after the heat treatment of workpieces mechanical property fluctuation bigger, can't effectively cool off workpiece.
Summary of the invention
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, and cooling power is strong, effectively the vertical vacuum water quenching oven water circle device of improve production efficiency and product quality stability.
The utility model is realized through following technical scheme:
Vertical vacuum water quenching oven water circle device; Its special character is to comprise the water pipe 5 that is installed on 2 outsides, vertical vacuum water quenching oven cold house; The two ends up and down of water pipe 5 all stretch in the body of heater, and contact with the intravital heat-eliminating medium of stove, and the tube wall place, top of water pipe 5 is arranged with the ejector nozzle 7 that communicates with it; The quantity of ejector nozzle 7 is corresponding with the number of plies of charging basket in the body of heater; The jet hole of ejector nozzle 7 is facing to the position of charging basket axis and cold house's 2 sidewalls 1/3rd to 2/3rds, and it is mobile to make quenchant between the workpiece form horizontal rotation, and the water pump 6 that is used for the heat-eliminating medium of bottom of furnace body is evacuated to ejector nozzle 7 places is installed on the water pipe 5;
Said ejector nozzle 7 is 15-30 degree angle with horizontal direction.
The utility model vertical vacuum water quenching oven water circle device; Be to have increased by a cover side recycle system on the basis of existing technology, overcome original equipment circulation cooling circulation ability defect of insufficient up and down, circulation ability increases; Every layer can be strengthened batch; Can improve more than batch 3-4 times, solve the mechanical property fluctuation that does not freely cause because of work-piece cools simultaneously, improve production efficiency and constant product quality property greatly.
