Description
Technical Field
The invention relates to the field of glass tea set manufacturing, in particular to high-boron glass tea set stress relieving equipment.
Background
In the high-boron tea service industry at present, the working procedures of heating to 560+/-10 ℃ and eliminating stress mainly comprise the working procedures of welding a handle, pulling a nozzle and forming a water gap, and the production of the three working procedures is all manual operation. The handle is affected by full manual operation, and the stress is overlarge due to a plurality of uncontrollable factors in the handle welding and water gap forming processes, so that a stress eliminating process after forming is needed to reduce the recent damage caused by the stress and the damage affected by cold and heat alternation in the use process of customers, wherein the uncontrollable factors mainly refer to the optimal temperature, the optimal forming speed, the optimal preheating uniformity before the product forming and the like.
At present, the high boron stress eliminating procedure mainly comprises the following two modes:
firstly, a gas furnace is utilized. The appearance of the furnace is almost the same as that of a household electric furnace, and an operator puts a finished product or a semi-finished product on a gas furnace for stress relief after finishing the welding and forming process of the high-boron glass tea set. This approach has a number of drawbacks, such as: 1) When the gas furnace works, carbon monoxide is generated and diffused in the working environment, so that the gas furnace has a certain influence on human health; 2) The available area of the gas furnace is smaller, only 1-2 high-boron tea sets can be put at a time, the productivity is too low, the problems of uneven heating and upper cooling exist in the stress elimination process, the stress elimination in the real sense can not be achieved, and the product quality is greatly influenced; 3) Because the gas furnace continuously works, when a product is taken down by using a handheld clamp on the gas furnace, operators are easy to accidentally scald to cause industrial injury, meanwhile, the gas furnace is generally close to a human body, the distance is about 70CM, and the heat radiation of the gas furnace to the human body in summer is easy to cause heatstroke of personnel; 4) The stove is always in open combustion, most of generated heat energy is released in the air, the energy utilization rate is low, waste is large, and the working environment is bad.
And secondly, a bread oven is utilized. The so-called bread oven is a circular oven, the interior of the oven is electrically heated, the upper part of the oven is provided with an opening and a cover plate, the mode of using the bread oven for stress relief is advanced compared with a gas oven, the environment pollution is less, and the following defects still exist: 1) The cover is opened once every time the bread oven is put in and taken out, and the heat energy stored in the bread oven can be discharged once every time the cover is opened, so that the waste of electric energy can be caused; 2) When the human body is put in and taken out, strong heat waves radiate on the upper body of the human body, and heatstroke occurs in summer; 3) Since the semi-finished products or finished products of the high-boron tea set enter the bread oven from the ambient temperature or enter the bread oven from the temperature in the higher bread oven, the stress relief process can lead to the crushing of many high-boron products due to the stress effect, the main reason is that the temperature is suddenly changed, the gradual temperature change (gradually rising or gradually falling) cannot be achieved, and the stress relief is not ideal in practice; 4) The products are easily scalded when being taken out of the bread oven by using the manual clamp.
In addition to the two modes, similar stress relief devices are also available, but are used for soda lime glass products, and the stress relief devices special for high-boron glass tea sets are not available at present. The structure, temperature gradient, main components, material selection and the like of the soda lime glass product stress relief device can not meet the stress relief requirements of the high-boron tea set.
The stress relief mode of the high-boron tea set is integrated, and the following defects mainly exist: 1) The productivity is low; 2) The safety of human bodies cannot be ensured (work injury and heatstroke); 3) The stress of the product is not thoroughly eliminated, the stress elimination requirement in the true sense is not met, the product quality is greatly influenced, the breakage rate is higher, and the breakage rate caused by the stress is generally 1% -3%; 4) The energy waste is large; 5) The working environment is polluted, so that the working environment becomes bad.

The residual heat recycling device can effectively utilize residual heat, thereby achieving the purposes of saving electric energy and reducing energy consumption. The temperature of the two ends of the device, namely the temperature of the outer ends of the feed inlet and the discharge outlet is equal to the ambient temperature, thus thoroughly avoiding the radiation of residual heat to human bodies.
