Description
Technical Field
The invention relates to the technical field of enamel enameling, in particular to a system and a method for controlling enameling of an inner container of an enameling machine.
Background
With the progress of the current society, energy conservation and emission reduction become important contents of the development of the current society, and the energy conservation and emission reduction become important development directions for the reasonable and effective use of various clean energy sources such as solar energy, wind energy and the like. The vast majority of people in China have abundant solar energy resources, so that the solar water tank serving as a traditional simple solar energy utilization mode is used in a wide area in China for years. The solar water tank can convert solar energy into heat energy, so that water in the liner is heated from low temperature to high temperature, and the requirement of hot water in life and production of people is met.
The existing solar water tanks all comprise inner containers, and circulating media transfer heat to water in the inner containers through heat conduction. Due to the requirement of corrosion resistance, most of the inner containers of the existing solar water tanks need an enamel layer, and the preparation method of the enamel layer comprises the steps of pulping glaze raw materials, driving the raw materials into the enamel inner container through a pulp inlet pipe, and utilizing a driving device to drive the outer surface of the inner container to rotate the inner container; the glaze slip can be uniformly coated on the inner surface of the inner container through the rotation of the inner container and the overturning action of the swinging bracket, and then after drying and sintering, the glaze slip is melted, condensed on the metal plate of the inner container and tightly combined with the metal plate. In the process, a plurality of important problems need to be considered, namely the corrosion resistance of the enamel, because although the enamel has the corrosion resistance, the water in the liner still inevitably corrodes the surface of the enamel after long-term use, and is gradually dissolved and peeled off, so that the service life of the liner is reduced. Another very critical problem is that the glaze slip needs to be uniformly coated on the inner surface of the liner in the enameling process, but the current operation mode is to rotate and turn the liner to make the glaze slip naturally attached to the inner surface without any external acting force, and the thickness of each part is inevitably different because the glaze slip is fluid. It is difficult to achieve uniform coating of the glaze slurry. Meanwhile, when the enameling machine performs overturning and rotating actions, an induction control mode is adopted, and due to the sensitivity problem of an induction device, errors are easy to occur, so that the problems of coating are caused.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only illustrative and are not intended to limit the present application.
The overall process of enameling by the enameling machine disclosed by the present invention is schematically described below.
(1) Preparing glaze slip:
the raw material components adopted by the invention at least comprise: silicon dioxide: 52-58 parts by mass of feldspar powder: 48-50 parts by mass of boric anhydride: 18-25 parts by mass of alumina: 4-6 parts by mass, the sum of cobalt oxide and nickel oxide: 1.2-1.6 parts by mass of soda: 4-6 parts by mass of calcium carbonate: 1-3 parts by mass of kaolin: 2 to 3 parts by mass.
In the components of the invention, silicon oxide and feldspar powder are used as base materials, boric anhydride and alkalis are added as functional components for reducing the melting point of the base materials, and the thermal expansion coefficient of the soda ash is adjusted at the same time. As for the amount of cobalt oxide and nickel oxide, in the actual production, the addition of feldspar powder into cobalt oxide and nickel oxide can make the glaze more fusible, improve the viscosity, reduce the surface tension gradually and make the glaze more easily coated on the surface of a steel plate. After the product is detected, the addition of the cobalt oxide and the nickel oxide can form a partial microcrystalline phase after sintering, and the compressive strength is also obviously improved. Through multiple experiments on the dosage of the base component and each functional component, and comprehensive comparison of the influence on performance and cost consideration, the optimal dosage combination is finally selected, namely, the glaze component of the invention meets the following relationship, (silicon oxide + feldspar powder), (boric anhydride + soda), and (cobalt oxide + nickel oxide) ═ 100: (24-28) are (1.4-1.6).
And uniformly mixing the prepared raw materials by using a ball-milling mixer, and adding deionized water to obtain the glaze slip used by the invention.
(2) Enameling process
The enamelling mechanism of the invention is partly based on the enamelling machine of the applicant's prior application CN201611226055.X, and is improved on the basis of the principle, and the detailed description is as follows:
the first improvement of the invention is that as shown in figure 1, the guniting mechanism of the invention comprises a grout inlet pipe 1, the grout inlet pipe 1 is positioned inside a chassis hollow shaft 2, a gap is arranged in the middle of the grout inlet pipe, the chassis hollow shaft 2 is arranged on a chassis bearing 3 and a chassis bearing seat 4, the grout inlet pipe 1 is connected with a guniting pump, and the chassis hollow shaft 2 is connected with a high-pressure air source.
In the prior invention, during the enameling operation, after the slurry spraying pump drives the glaze slurry into the enamel liner through the slurry inlet pipe, the glaze slurry is coated on the inner surface of the liner through the rotation of the liner and the overturning action of the swing bracket; then the glaze slurry flows out into a recovery hopper through a pore passage between the hollow shaft of the chassis and the slurry inlet pipe. The enameling mode completely depends on the gravity of the glaze slip to flow in the rotating and overturning processes and coat the glaze slip on the surface of the liner, the flowing process is uncontrollable, gaps generated by assembly often exist at certain positions of the liner, such as the root of a water pipe and the welding position of a seal head, the joint and the like are easily coated, and meanwhile, the glaze slip is gradually reduced in the coating process, so that the coating of the liner is not uniform enough. Meanwhile, in the subsequent drying process, the thickness of the glaze slurry on the inner surface of the coated inner container is changed due to the fact that the inner container is moved, and the like. The quality of the product is also seriously affected.
In order to solve the problem, the invention is creatively improved on the basis of the original enameling mechanism, and a high-pressure air source is connected with a hollow shaft of a chassis. After the glaze slip is squeezed into the enamel inner container through the slip inlet pipe, the pressure in the inner container is increased through a high-pressure air source, coating work is carried out under certain pressure, the glaze slip is rotated and overturned in the inner container, the glaze slip not only bears the action of gravity, but also bears the action of air pressure, flowing is more stable, the glaze slip on the inner surface after coating bears the action of pressure, thickness change is not easy to occur when the enamel slip is moved, and coating quality is obviously improved. In the embodiment, the pressure used in the inner container is 0.3-0.5 MPa.
In another more improved solution, a pressure of 0.3MPa is used in the initial stage of coating, and the pressure is increased gradually as the coating progresses, and the pressure is increased to 1.5 times the initial pressure at the end of coating.
The second improvement of the invention is that when the control system of the enameling machine and the prior enameling machine perform overturning and rotating actions, an induction control mode is adopted, and because of the sensitivity problem of an induction device, errors are easy to occur, so that coating problems occur. The invention improves the problem, and the travel limit switches are respectively arranged at the initial position and the guniting position of the enameling machine and acquire the limit position signals of the swing bracket. The swinging of the swing bracket of the enameling machine, the pause of any angle position, the rotation of the workpiece and the compression and release of the workpiece are controlled by a control system.
The control system controls the enameling machine to drive the workpiece to rotate at a preset speed in the process of putting the workpiece into the enameling machine for enameling, simultaneously swings and pauses at various angles, and except for the initial position and the guniting position, limit position signals need to be collected, other actions are completed without collecting external signals, and the omnibearing enameling inside the workpiece is realized by setting the time length of each action. The control system controls the workpiece to swing and pause at a preset angle relative to the control system for acquiring external signals, and avoids system control abnormity caused by external signal faults.
The control system of the invention adopts a mode of combining manual control and automatic control, controls the coating process by using time, and can realize coating at 360 degrees without dead angles.
