Problems solved by technology

The disadvantages of this method are: the air and dust pollution of the combustibles are relatively large, the thermal efficiency is low, and the heat loss is large.
The above disadvantages lead to the inability to effectively remove the paint layer of the board. It is necessary to repeat the above steps ② and ③ many times, and even need to use manual labor to remove it.

Embodiment 1

[0021] See attached figure 1 to attach figure 2 As shown, in this embodiment, a non-cooking waste metal paint layer heat removal device includes a thermal paint removal mechanism 1 and a scrubbing brush mechanism in sequence along the conveying direction of waste boards. The thermal paint stripping mechanism 1 of this embodiment is used to heat-treat the slowly fed waste boards, so that the metal part of the waste boards can self-heat. The heated electromagnetic heating unit 11 and the pressure roller 12 made of non-metallic material, the pressure roller 12 of this embodiment can adopt a soft roller surface (such as a rubber roller surface) or a hard roller surface (such as a wooden roller surface). The pressure roller 12 is arranged close to the heating surface of the electromagnetic heating unit 11 so that a gap for the metal plate to pass is formed between the roller surface of the pressure roller 12 and the heating surface, and the width of the gap is equal to or slightl...

Embodiment 2

[0028] See attached image 3 to attach Figure 4As shown, the difference compared with Embodiment 1 is that this embodiment also includes a set of feeding rollers located at the inlet end of the thermal stripping mechanism 1, wherein the set of feeding rollers is composed of two flattened feeding rollers that are closely matched to each other. Composed of rollers 4, the roller surfaces of the two flattening and feeding rollers 4 are made of hard materials, and the two flattening and feeding rollers 4 rotate in opposite directions to play the role of pulling and pressing the waste boards, so that the waste boards are flattened to form a flat surface The plate is conveniently sent to the downstream thermal paint stripping mechanism 1 and scrubber mechanism for processing, effectively avoiding the problem of residual paint layer at the raised or bent position caused by the unevenness of the waste plate.

[0029] Further, in any of the two flattening feed rollers 4 of the same gr...

Embodiment 3

[0031] See attached Figure 5 And attached Image 6 As shown, the difference compared with Embodiment 1 and Embodiment 2 is that the thermal paint stripping mechanism 1 of this embodiment includes a heating box and an electromagnetic heating unit 11 that is surrounded by an inner wall of the heating box, wherein the heating box The middle position is formed with a horizontally penetrating hole, and the electromagnetic heating unit 11 ring is set on the inner wall of the hole, so that the waste plate can be buffered and penetrated from the middle position of the heating box, and the electromagnetic heating unit 11 ring is set on the waste plate At the periphery, the electromagnetic heating unit 11 is used to heat the waste boards through ring-shaped electromagnetic induction, thereby further increasing the self-heating rate of the waste boards and accelerating the temperature rise and dissolution of the adhesive surface in the paint layer.

[0032] To sum up, in Embodiment 1, ...

Abstract

The invention discloses a cooking-free heat removal device for a waste metal paint layer. The cooking-free heat removal device for the waste metal paint layer sequentially comprises a hot depainting mechanism and a scrubbing brush mechanism along the conveying direction of waste plates, wherein the hot depainting mechanism is used for carrying out heat treatment on the waste plates which are slowly fed to enable the metal parts of the waste plates to be heated by the metal parts, the scrubbing brush mechanism comprises at least one pair of steel wire brush rolls which are arranged oppositely and rotate at a high speed; and a gap for allowing the waste plates subjected to heat treatment to slowly pass in a penetrating manner is formed between the roll surfaces of each pair of steel wire brush rolls, and each pair of steel wire brush rolls sequentially performs scrubbing and polishing treatment on the upper surfaces and the lower surfaces of the waste plates subjected to the heat treatment. By utilizing the mode, the separation between the paint layer and the plates is more thorough, and the whole thermal removal process is more environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the technical field of waste metal paint layer treatment, in particular to a heat-removing device for cooking-free waste metal paint layer. Background technique [0002] At present, the resource recycling of iron packaging barrels mainly includes the following methods: 1) After the packaging barrels are recycled, they are cleaned and recycled directly; 2) After being shredded and crushed, they are used as raw materials for steelmaking and transported to steelmaking plants It is returned to the furnace to be smelted into steel, and then rolled into finished cold-rolled plates. For the second type of recycling, there are many intermediate links, and the consumption of manpower, material resources, transportation, energy, etc. is large, which does not conform to the low-carbon environmental protection concept advocated by the state. However, for the first method, such packaging barrels will be coated with a large number of paint ...
