A film coating device for the water-cooled wall heating surface of a waste incineration boiler

Abstract

The present invention relates to the technical field of waste incineration boilers, and specifically relates to a film coating device for the water-cooled wall heating surface of a waste incineration boiler. The heating surface rotation assembly includes a component bottom bracket, a motor shaft, a transmission gear, a rotating disc, external teeth, a magnetic attraction circular frame, a limit baffle and a central through groove. Through the setting of the present invention, it is convenient to limit and lock the position of the heating surface to be film-coated by means of the magnetic attraction circular frame and the limit baffle. At the same time, the film roll is directly arranged inside the heating surface. Under the restriction of the pressing roller and the rotation of the heating surface, the film will automatically adhere to the heating surface. Further, during the film adhesion process, it will drive the rotation near the pressing roller. Further, the two reciprocating movements flatten and move outward or inward at the same time, so that the film is flattened during the adhesion process, which is beneficial to the flatness of the film coating.

Description

Technical Field

[0001] The invention relates to the technical field of garbage incineration boilers, in particular to a coating device for a heating surface of a water-cooled wall of a garbage incineration boiler. Background Art

[0002] Garbage is waste that has lost its use value and cannot be used. It is an important part of the material cycle. It is solid or fluid material that is not needed or useful. In densely populated cities, garbage disposal is a headache. The common practice is to collect and send it to landfills for landfill treatment, or to incinerate it in incinerators. Therefore, garbage needs to be incinerated with the help of garbage incineration boilers, which include heating surfaces to facilitate the drying of garbage. However, the heating surface needs to be coated due to labor requirements.

[0003] At present, the heating surfaces used in garbage incineration boilers are mostly cylindrical surfaces, which means that the heating surfaces of the garbage incineration boilers need to be coated with a circle of film. At the same time, manual coating is often used in the coating process of the existing heating surfaces. Manual coating has the disadvantage of taking a long time. At the same time, since the heating surface is cylindrical, the film needs to be bent during the process of manually coating the heating surface, which leads to uneven coating when the film is coated on the heating surface, affecting the coating quality of the heating surface.

A fixedly connected platform providing ring 102 is sleeved on the outer periphery of the lower side of the inserted support rod 101. With the help of the inserted support rod 101 and the platform providing ring 102, the film roll 103 is inserted on the inserted support rod 101, so that the heat insulation film 104 is at the center of the heat receiving surface.

[0029] The rotating disc 13 drives the pressing roller 1302 close to it to rotate through the fixed base 1301, and the heat insulation film 1304 is continuously released. The pressing roller 1302 close to it makes the heat insulation film 1304 fit on the inner wall of the heat receiving surface.

[0030] The inner wall film covering assembly includes a supporting rod 2, a reciprocating flattening rod 21, an internal sliding groove 22, a first return spring 23, a sliding rod 24 in the groove, and a staggered arc-shaped block 25. Among them, the reciprocating flattening rod 21 is embedded in the middle position at one end of the supporting rod 2. The internal sliding groove 22 is opened in the middle position at the inner end of the supporting rod 2. The first return spring 23 is located on the upper and lower sides inside the internal sliding groove 22. The sliding rods 24 in the groove are symmetrically arranged inside the internal sliding groove 22. The staggered arc-shaped block 25 is fixed at one end of the sliding rod 24 in the groove close to the middle of the internal sliding groove 22. The end face of the staggered arc-shaped block 25 in contact with the double-sided pushing block 2501 is an arc surface.

[0031] The supporting rod 2 is fixedly connected to the fixed base 1301. The number of reciprocating flattening rods 21 arranged is two. A single reciprocating flattening rod 21 is fixedly connected to the corresponding sliding rod 24 in the groove. The two sliding rods 24 in the groove are located between the two first return springs 23, and there is a gap between the two sliding rods 24 in the groove.

[0032] A double-sided pushing block 2501 is placed between the two staggered arc-shaped blocks 25. Among them, an internal and external through rod 2502 fixedly connected is arranged at the middle position of one end of the staggered arc-shaped block 25. The internal and external through rod 2502 penetrates through one side of the supporting rod 2. A second return spring 2503 is sleeved on the internal and external through rod 2502. One end of the internal and external through rod 2502 is inside the middle fault 1303. An end protrusion 2504 fixedly connected is arranged at the end of the internal and external through rod 2502 inside the middle fault 1303.

[0033] During the process of laying the heat insulation film 104, since the pressing roller 1302 rotates nearby, the heat insulation film 104 is laid on the heated surface. And during the rotation of the pressing roller 1302 nearby, the top block 1304 pushes the end protrusion 2504. The internal and external through rod 2502 drives the double-sided pushing block 2501 to move inward, and the second return spring 2503 deforms. Further, under the action of the staggered arc-shaped block 25, the two sliding rods 24 in the groove will be pushed open by the double-sided pushing block 2501. At this time, the reciprocating flattening rod 21 moves upward. At the same time, under the action of the first return spring 23, the reciprocating flattening rod 21 will move inward again. This is convenient for flattening the heat insulation film 104. Then, the heat insulation film 104 is cut, and the two ends of the heat insulation film 104 are butted head to tail.
