Description

Technical Field

[0001] The invention relates to equipment for spraying enamel on the end cap of the inner tank of a water heater, in particular to automatic spraying enamel and edge blowing equipment for the end cap of the inner tank of a water heater and a glazing room with the equipment. Background Art

[0002] In the prior art, manual spraying is generally used for spraying the outer surface of the water heater inner tank head. That is, in a spraying room, a person manually sprays glaze on the outer surface of the water heater inner tank head with a handheld glaze spray gun. In order to prevent the glaze on the edge of the head from affecting the subsequent welding of the head, the glaze on the edge of the head needs to be removed. The existing method of removing the glaze on the edge of the head is to manually remove, blow or protect it with a brush. The existing method of using manual spraying cannot guarantee the quality of spraying, so that the spraying thickness of the head cannot be guaranteed to be uniform; secondly, the efficiency of manual spraying is low, which affects the improvement of the production capacity of the production line. After the spraying is completed, the glaze on the edge of the head is removed, blown or protected with a brush, but it cannot be guaranteed that the cleaning is completely clean and accurate.

[0052] Preferably, the inner bottom surface 2131 of the glaze receiving groove 213 is a slope sloping downward from the side of the spraying portion 211 to the side of the exhaust duct 212 .

[0053] An inner bottom spray washing pipe 2132 is provided on the side of the slope close to the spraying part 211, which can form a water curtain on the slope to take away the fallen glaze particles in time, and also has a certain flushing and cleaning effect on the slope to achieve the purpose of self-cleaning.

[0054] Preferably, an exhaust gas spray washing pipe 2122 is provided at the upper part of the exhaust duct 212, and a plurality of relatively staggered baffles 2123 are provided in the exhaust duct 212. A glaze water separator 2124 is provided at the middle and upper part of the exhaust duct 212.

[0055] The glaze water separator 2124 includes a separator box 21241, and a plurality of through holes are provided on the upper bottom plate and the lower bottom plate of the separator box 21241, and a plurality of parallel arranged barbed partitions 212412 are provided in the separator box 21241; when the glaze mist reaches the barbed partition 212412, the glaze mist will be deflected, and the airflow will turn, and the heavy objects and large particles of glaze in the airflow will be thrown out by centrifugal force, so as to achieve the purpose of further separating the glaze.

[0056] The following is an introduction to the method of using the present invention (only two self-rotating mechanisms 132 are used as examples for explanation. The reader can refer to the following description for explanation of 3-6 self-rotating mechanisms 132, which will not be repeated here). Before starting the machine, the exhaust system fan and the spray water washing pump of the glazing room main body 210 are started. After normal operation, the water heater inner tank head 160 that needs to be sprayed is manually placed on one of the head trays 1324. The positioning lock 13242 on the adjustable head tray 1324 limits the water heater inner tank head 160. The rotation axis of the water heater inner tank head 160 coincides with the rotation axis of the head tray 1324. The revolution drive motor 1221 is started, and the head turntable 1324 with the water heater inner tank head 160 is rotated 180 degrees and then stopped. After the water heater inner tank head 160 is in place, the self-rotating drive of the spraying station The motor 1321 rotates. After the speed of the self-rotation drive motor 1321 stabilizes, the spray gun 145 is opened to spray the outer surface of the water heater inner tank head 160. Workpieces of different sizes can be evenly sprayed by adjusting the number of spray guns 145 opened. When the water heater inner tank head 160 completes the spraying operation, the switch of the edge blowing mechanism 150 is turned on, and the lower edge position of the water heater inner tank head 160 is blown. After the set time is reached, the edge blowing mechanism 150 stops moving, the self-rotation drive motor 1321 of the spraying station stops rotating, and the revolution drive motor 1221 is started to send the sprayed water heater inner tank head 160 out of the glazing room body 210, and wait for the water heater inner tank head 160 to be taken away manually. After the workpiece is taken away, the untreated water heater inner tank head is installed on the head tray 1324 to continue the spraying operation. The glaze receiving groove 213 of the glaze spraying room body 210 and the air duct 212 at the rear end of the glaze spraying room body 210 are respectively provided with an inner bottom spray washing pipe 2132 and an exhaust gas spray washing pipe 2122. The inner bottom spray washing pipe 2132 can timely take away the glaze falling into the glaze receiving groove 213. Some glaze paint mist that has not fallen into the glaze receiving groove 213 enters the air duct 212 at the rear end of the glaze spraying room body 210 along with the exhaust air. The air duct 212 at the rear end is provided with a three-layer wind deflector 2123. When the wind containing the glaze passes through the wind deflector 2132, it is discharged at the exit. Under the action of centrifugal force, the heavier glaze small particles in the wind are thrown out and adhere to the wind baffle 2132. A glaze water separator 2124 special for glaze blocking is also provided in the air duct 212, which can further separate the glaze particles in the air duct 212. At the same time, an exhaust gas spray washing pipe 2122 is provided above the glaze water separator 2124 to spray and flush the glaze water separator 2124 to reduce the accumulation of glaze on the glaze water separator 2124 and avoid clogging the air path. At the same time, the spraying water will also form a water mist net to further capture the glaze particles in the exhaust air and make the exhaust air further clean.

[0057] In this embodiment, a straight-line turntable 131 is used, and a rotating arm hoisting installation method is adopted to place the revolution drive mechanism 122 of the revolution mechanism 120 above the glaze spraying room body 210, which effectively reduces the damage of the spray mist to the revolution drive mechanism 122. The general maintenance of the revolution drive mechanism 122 only needs to be handled outside the glaze spraying room body 210, and there is no need to enter the glaze spraying room body 210, thereby avoiding the inconvenience of operation caused by the narrow internal space of the glaze spraying room body 210.

[0058] In the present invention, the glaze spraying room main body 210 and the straight-line turntable 131 are combined, which can reduce the labor intensity of personnel and improve the spraying environment, improve production efficiency, and separate and treat the spraying waste gas, thereby reducing the processing pressure of subsequent waste gas treatment equipment, reducing the initial investment cost of the equipment and the subsequent maintenance cost.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
