Description

Technical Field

[0001] The utility model relates to the technical field of enameling machines, in particular to a horizontal enameling machine. Background Art

[0002] The enamel used in the enameled wire production process contains a large amount of diluents and organic solvents, the main components of which are benzene, xylene and cresol, which evaporate when the paint film is heated and cured, causing environmental pollution and energy waste.

[0003] The Chinese utility model patent with the authorization announcement number "CN208189305U" is specifically "a horizontal enameling machine". Its specification records in the beneficial effects that "the horizontal enameling machine provided by the utility model, during the painting process, the harmful gases volatilized by the painting device will be collected by the smoke hood, and under the action of the negative pressure in the oven, enter the oven cavity from the inlet of the oven, and are discharged after being burned in the oven cavity, thereby reducing the volatilization of harmful substances and improving the utilization rate of energy.";

[0004] The above-mentioned device extracts the harmful gases generated in the production process of the enameled wire into the drying furnace for combustion. Although it can reduce the volatilization of harmful substances, it will also simultaneously extract the high-temperature air in the inner cavity of the enameling machine while extracting the harmful gases, which will reduce the temperature in the inner cavity of the enameling machine and make it difficult to meet production requirements. The heating equipment needs to be continuously heated at high load, which results in a waste of resources. In addition, the harmful gases cannot be completely treated by combustion, and the gas discharged from the output end of the drying furnace still contains a small amount of harmful substances, resulting in incomplete treatment. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a horizontal enameling machine, which can effectively solve the problems of resource waste and incomplete processing in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] Furthermore, a fan is fixedly installed on the top of the enameling machine body, the input end of the fan is connected to the inner cavity of the enameling machine body, and a first solenoid valve is installed between the output end and the input end of the combustion chamber.

[0009] Furthermore, a second solenoid valve is installed between the input end of the purification chamber and the output end of the combustion chamber, and a return pipe is connected between the output end of the purification chamber and the inner cavity of the enameling machine body.

[0010] Furthermore, the inner cavity wall on the same side of the insertion cavity is provided with a slot having a diameter matching the filter cage and the cover plate through the outer wall of the purification chamber, and the diameter of the slot is smaller than the cross-sectional specification of the corresponding insertion cavity. Through holes are provided through the insertion cavities, and the insertion cavities are connected to the input and output ends of the purification chamber.

[0011] Furthermore, a slot is provided on the top of the filter cage, and an insert frame adapted to be inserted into the corresponding slot is installed on the bottom of the cover plate.

[0012] Furthermore, a limit handle is installed on the side of the filter cage away from the purification chamber.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. The utility model not only installs a combustion chamber above the enameling machine to perform preliminary combustion treatment on the toxic gas generated in the enameled wire production process, and decomposes most of the toxic substances into carbon dioxide and water, but also sets a purification chamber at the output end of the combustion chamber to perform secondary filtration and purification on the gas discharged from the combustion chamber through activated carbon, so that the harmful substances are treated more thoroughly.

[0015] 2. At the same time, the thoroughly purified gas discharged from the clean room flows back to the inner cavity of the enameling machine through the return pipe, eliminating the waste of a large amount of high-temperature air, so that the temperature of the inner cavity of the enameling machine remains balanced, and there is no need for continuous high-load heating by heating equipment, which has the advantage of saving resources.

The filter cage 51 is filled with activated carbon, and a cover plate 53 is detachably installed on the top to prevent the activated carbon from leaking when the filter cage 51 is loaded and unloaded. A magnetic strip 55 that is magnetically adsorbed to the corresponding baffle 45 is embedded and installed at one end of the filter cage 51 in the same direction. Through the adsorption of the magnetic strip 55 on the baffle 45, when the filter cage 51 is drawn out of the corresponding insertion cavity 43, the high-temperature gas will be blocked by the baffle 45 and will not leak out from the slot.

[0027] Example 2

[0028] Reference Figure 1-5, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a fan 3 is also fixedly installed on the top of the enameling machine body 1 to accelerate the circulation of gas. The input end of the fan 3 is connected to the inner cavity of the enameling machine body 1, and a first solenoid valve 31 is installed between the output end and the input end of the combustion chamber 2 to control the opening and closing of the circulating gas path. A second solenoid valve 41 is installed between the input end of the purification chamber 4 and the output end of the combustion chamber 2 to control the opening and closing of the circulating gas path. A return pipe 42 is connected between the output end of the purification chamber 4 and the inner cavity of the enameling machine body 1. The inner cavity wall on the same side of the insertion cavity 43 penetrates the outer wall of the purification chamber 4 and is provided with a diameter of The filter cage 51 and the cover plate 53 are adapted to have slots, the diameter of which is smaller than the cross-sectional specifications of the corresponding insertion cavity 43, so that the retaining bar 45 can slide linearly back and forth in the insertion cavity 43 but cannot be removed through the slots. Through holes 44 are provided between the insertion cavities 43, and the insertion cavities 43 are connected to the input and output ends of the purification chamber 4. A slot 52 is provided at the top of the filter cage 51, and an insertion frame 54 adapted to be inserted into the corresponding slot 52 is installed at the bottom of the cover plate 53. A limit handle 56 is installed on the side of the filter cage 51 away from the purification chamber 4, which limits the filter cage 51 and facilitates the disassembly, assembly, withdrawal and placement of the filter cage 51.

[0029] The remaining structures are the same as those of Example 1.

[0030] The workflow of this utility model is as follows:

[0031] First, when the enameling machine body 1 is working, harmful gas is generated. By opening the fan 3 and the first solenoid valve 31, the harmful gas is extracted into the combustion chamber 2, and the ignition device in the combustion chamber 2 is started to burn the harmful gas at high temperature. In order to ensure thorough combustion, the second solenoid valve 41 is closed at this time, and the first solenoid valve 31 is also closed after being opened for a period of time. When the combustion in the combustion chamber 2 is finished, the first solenoid valve 31 and the second solenoid valve 41 are opened to continue to let air into the combustion chamber 2 through the fan 3, so that the gas in the combustion chamber 2 that has been purified by combustion is discharged into the purification chamber 4;

[0032] Secondly, the burned gas entering the purification chamber 4 needs to pass through a plurality of filter cages 51 filled with activated carbon respectively, and is adsorbed by the activated carbon for secondary purification when in contact with the activated carbon. The purified air finally flows back into the inner cavity of the enameling machine body 1 due to the pressure difference between the purification chamber 4 and the enameling machine body 1, thereby completing the circulation purification of harmful substances under the premise of reducing the heat loss in the inner cavity of the enameling machine body 1.

[0033] Finally, in order to ensure that the activated carbon in the purification chamber 4 always has a high-efficiency adsorption and purification effect, the activated carbon in the purification chamber 4 needs to be replaced regularly. The method is to extract the filter cage 51 through the limit handle 56 to take out the activated carbon in the filter cage 51. At the same time, the magnetic strip 55 on the side of the filter cage 51 is magnetically adsorbed with the baffle 45 slidably installed in the insertion cavity 43, so they will also slide synchronously. When the baffle 45 slides to the slot, the baffle 45 is forced to separate from the filter cage 51 because the specification of the baffle 45 is larger than the specification of the slot, and is sealed at the slot to avoid the loss of hot gas in the corresponding slot 52 and cause waste.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
