The differential pressure transmitter is further provided with a pressure gauge. The full-automatic pressure controller comprises a pressure signal digital-to-analog conversion device and a positive-negative feedback and scheduled scanning device. The system suffers from less influence of factors, such as quality and professional technological level of people, and regulates the pressure in real time with high precision, thus, in actual use, stress balance of glass can be kept more easily, and the quality of glass can be guaranteed more easily.
Description
Technical field
The utility model particularly relates to the full-automatic control system of horizontal roller formula cooling air grid blast equilibrium in the glass tempering production about a kind of full-automatic control system.
Background technology
The last air grid 8 of horizontal roller formula glass tempering cooling air grid (tempering cooling section) and following air grid 9 were made up of the tuyere 10 that N group spacing equates respectively during existing employed glass tempering was produced, affixed with the hermetically enclosed type pulling rivet of seal gum between every group of tuyere 10 and bellows, last air grid 8 and following air grid 9 relative roller-ways symmetric offset spread about in the of 13, as shown in Figure 1.When roller-way 13 upper surfaces of glass through rotatablely moving that reach tempering temperature (about 720 ℃) pass through, the high pressure draft that the tuyere 10 of last air grid 8 and following air grid 9 blows out covers toughened glass 11 upper and lower surfaces equably, glass surface is cooled off fast, reach the tempering purpose that indexs such as planeness, granularity meet related standards.
In the tempering process, for guaranteeing the granularity requirements of toughened glass 11, except air-flow should satisfy certain pressure, for guaranteeing the planeness of toughened glass 11, requirement to toughened glass 11 upper and lower surperficial stress equalizations (pressure of namely going up the air-flow that the tuyere 10 of air grid 8 and following air grid 9 blows out should equate) is more strict, purpose be prevent glass in air grid, produce floating, beat etc.
The balance control system of the stream pressure (hereinafter to be referred as the blast of upper and lower air grid) that the tuyere 10 of the last air grid 8 of horizontal roller formula glass tempering cooling air grid (tempering cooling section) and following air grid 9 blew out during existing glass tempering was produced is seen Fig. 2, as shown in the figure, the blast of last air grid 8 and following air grid 9 all adopts control manually by hand controller 12.Because system adopts control manually, be subjected to people's the influence of factors such as quality, level professional technology bigger, therefore, the result exists than mistake, and precision also is difficult for assurance, causes glass stressed unbalance, causes the glass quality instability.
Summary of the invention
The utility model provides the full-automatic control system of a kind of glass tempering cooling air grid blast equilibrium, to solve the technical problem that exists in the background technology.
For this reason, the full-automatic control system of a kind of glass tempering cooling air grid blast of the present utility model equilibrium, comprise the differential pressure transmitter, full-automatic pressure controller, topworks and the air collecting box that link to each other in turn, the little bellows of last air grid are connected described differential pressure transmitter respectively with the little bellows of following air grid, and described air collecting box links to each other with the little bellows of following air grid with the described little bellows of air grid of going up respectively.
Wherein, also be provided with manometer on the described differential pressure transmitter.
Wherein, described full-automatic pressure controller comprises pressure signal digiverter and positive reverse feedback and timing scan device.
The useful technique effect that the utility model reaches is, make glass bear the pressure equalization of the high pressure draft that upper and lower air grid tuyere blows out at roller-way, prevent that glass is floating in air grid, beat etc., reach related standards to produce indexs such as planeness, granularity, satisfy the toughened safety glass of customer requirements.Little because of the influence of the factors such as quality, level professional technology that are subjected to the people, pressure is carried out in real time and is adjusted, the sharpness of regulation height, so in actual use, the stress balance of glass is with easier maintenance, and the quality of glass is easier assurance also.

Embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and also be elaborated by reference to the accompanying drawings.
Fig. 3 is the structured flowchart of full-automatic control system of the present utility model, as shown in Figure 3, full-automatic control system of the present utility model comprises differential pressure transmitter 1, full-automatic pressure controller 2, topworks 3 and the air collecting box 4 that links to each other in turn, the little bellows 5 of last air grid are connected described differential pressure transmitter 1 respectively with the little bellows 6 of following air grid, and air collecting box 4 links to each other with the little bellows 6 of following air grid with the little bellows 5 of last air grid respectively.
Native system arranges blast from the little bellows 5 of last air grid with the little bellows 6 of following air grid respectively and takes a little, reach differential pressure transmitter 1 by PU flexible pipe or copper tube, after differential pressure transmitter 1 is measured the leeway that goes up between the little bellows 5 of air grid and the little bellows 6 of following air grid, this leeway is converted to electrical signal, is delivered to full-automatic pressure controller 2.Also be provided with manometer 7 on the differential pressure transmitter 1, show so that pressure data to be provided.
Full-automatic pressure controller 2 comprises pressure signal digiverter and positive reverse feedback and timing scan device, in order to differential pressure signal control topworks 3 actions of transmitting according to differential pressure transmitter 1, topworks 3 is according to the control signal of full-automatic pressure controller 2, change the air quantity of supplying with air collecting box 4 cavitys of going up the little bellows 5 of air grid and the little bellows 6 of following air grid respectively, thereby reach the pressure equalization of the little bellows of air grid 5 and the little bellows 6 of following air grid, the pressure that namely reaches the air-flow that the little bellows 5 of air grid and little bellows 6 tuyeres of following air grid blow out is equal.
