Abstract
The utility model provides a forced-convection glass steaming and pressing kettle, which comprises a kettle body, a gas pipe, a main heating pipe, a cooling pipe and an auxiliary heating pipe. A high pressure pulse gas feeding device is connected to a gas inlet. The auxiliary heating pipe consists of a plurality of infrared heating pipes which are parallelly arrayed, and the array heights of the infrared heating pipes are not higher than the center line of the cross section of the kettle body so that a larger spacing is arranged between the cooling pipe and each heating pipe to ensure use rate of an energy resource. High pressure gas fed by the gas inlet is delivered to the bottom of the inner wall of the kettle body via the gas pipe so that the high pressure gas is prevented from contacting with the cooling pipe first. The main heating pipe is arranged above a gas outlet of the gas pipe, so that the high pressure gas is firstly heated and then delivered to the top of the inner wall of the kettle body via a product to be processed. Since hot gas has the characteristic of flowing upwards while cold gas has the characteristic of sinking downwards, the product to be processed in the kettle body can be uniformly heated and is prevented from being local over-heated. Accordingly, the forced-convection glass steaming and pressing kettle has the advantages of higher energy source utilization rate, more reasonable heating and cooling methods and better quality of products.
Description
Technical field
The utility model relates to a kind of glass production autoclave, especially relates to a kind of forced convection glass autoclave of laminated glass production usefulness.
Background technology
Existing autoclave in use, the heating tube of still inner bottom part, the left and right sides is treated processed glass and is heated, and often has the uneven problem of being heated, and exists local heating to cross high situation, there is the inconsistent situation of transparency in the glass that causes producing, has influenced product quality and yield rate.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of energy utilization rate is higher, product is heated evenly and quality forced convection glass autoclave preferably.
For solving the problems of the technologies described above, the utility model provides a kind of forced convection glass autoclave, comprise: kettle, be located at the still door of kettle front end and be located at the seal closure of kettle rear end, inwall bottom at kettle is provided with main heating tube, be provided with the boosting pipe in the left and right sides of inner wall of kettle, it is characterized in that: be provided with partition between each boosting pipe and inner wall of kettle, the central authorities of the seal closure of kettle are provided with vacuum fan, and the blade of this vacuum fan is arranged in the air draft passage of described partition formation.
Further, described kettle is provided with inlet mouth, and the inwall of kettle is provided with the tracheae that links to each other with described inlet mouth, and the inwall bottom in kettle is provided with the air outlet on tracheae; The below of described main heating tube is located in the air outlet of described tracheae, is provided with cooling tube respectively and between the adjacent partition at the left and right sides inwall of kettle.
Further, the upper and lower edge of described partition links to each other with the inwall of kettle respectively, exists between the back edge of partition and the inwall of described seal closure at interval, exists at interval between the inwall of the front edge of partition and described still door.
The utlity model has positive effect: when working in (1) a kind of forced convection glass autoclave of the present utility model, vacuum fan makes heating air flow center on air draft passage and forms circulation, specifically: warm air under the effect of vacuum fan from kettle mind-set kettle rear end flow, interval between the inwall of the back edge of described partition and described seal closure, enter in the interval of described partition and inner wall of kettle, be back to the kettle center through the front edge of described partition and the interval between the still door then, thereby make warm air in still, form circulation, improved energy utilization rate and product is heated evenly and quality better.(2) for product is heated evenly, the high pressure gas that inlet mouth is sent into are delivered to the inwall bottom of kettle through tracheae, thereby avoid high pressure gas to contact with processed product earlier; The top, air outlet of described tracheae is provided with main heating tube, so that described high pressure gas are heated earlier, delivers to the inwall top of kettle behind product to be processed.Because hot gas is oriented go up to flow, the characteristic of the oriented sinking of cold air, so still is intravital can be heated equably through product to be processed, has avoided occurring the situation of local superheating.(3) when insulation, because the needs of production technique, the inlet mouth on the kettle need stop air inlet.And vacuum fan can work on, and can guarantee further that product is heated evenly, and prevents local superheating and influences product quality.
