Description

Technical Field

[0001] The utility model belongs to the technical field of iron removal from hazardous waste incineration residues, and in particular relates to a portable iron-absorbing device for hazardous waste incineration residues. Background Art

[0002] Hazardous waste refers to waste that is listed in the national hazardous waste list or is identified as having hazardous characteristics according to the national hazardous waste identification standards and identification methods. The existing hazardous waste disposal technology uses a rotary kiln to incinerate at a temperature above 1100°C. The hazardous waste is fully burned and decomposed at high temperature, and the incineration residue produced after incineration falls into the slag discharger at the tail of the rotary kiln.

[0003] Iron removal from incineration residue refers to the process of collecting the iron in the incineration residue from the incineration rotary kiln by a certain method to achieve comprehensive resource utilization. Since the incineration rotary kilns of hazardous waste disposal units produce a large amount of incineration residue every year, many hazardous wastes containing iron contain a large amount of iron in the residues after incineration. The existing devices are all for sorting large pieces of iron. However, the large number of small pieces of iron contained in the residue also have great recycling value, which is not easy to sort out in general operations. The methods for removing iron from incineration residues usually include flotation, gravity separation, etc. Since these methods have complex operating procedures and high operating costs, in order to meet production needs, it is very necessary to propose an effective, portable, low-cost iron removal device specifically for collecting small pieces of iron in incineration residues. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and to propose a portable iron-absorbing device for hazardous waste incineration residues. The iron-absorbing device can effectively and conveniently collect small pieces of iron less than 3 cm in the incineration residues, thereby maximizing the resource utilization rate and realizing harmless and high-value comprehensive resource utilization. After the iron is fully collected, the amount of residue that needs to be landfilled is reduced, thereby saving landfill, a non-renewable resource that occupies natural resources.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A portable magnetic magnet device for hazardous waste incineration residues, which consists of an oblong tube body, a magnetic magnet disk, and a support platform with a U-shaped small iron piece collection groove. The magnetic magnet disks are multiple and embedded in the oblong tube body. The magnetic magnet disks have the same arc surface as the outer surface of the oblong tube body, so that the surface of the embedding port is flat; the collection groove has a size that matches the outer surface of the oblong tube body. When the oblong tube body full of iron is pulled and drawn in the small iron piece collection groove for multiple times, the small iron pieces can fall off.

[0007] Preferably, the oblong tube is made of metal material, including but not limited to 304 stainless steel.

[0008] Preferably, the magnet is a permanent magnet, including but not limited to an aluminum nickel cobalt magnet.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] In the utility model, a large number of small pieces of iron in the hazardous waste incineration residue can be fully adsorbed by the magnetic magnet embedded in the oblong tube body, which is convenient and quick. Then the oblong tube body fully adsorbed with iron is placed in the small piece iron collection groove of the support table and pulled out multiple times, so that the small pieces of iron can be collected after falling off.

[0011] In summary, the utility model can conveniently and quickly absorb small pieces of iron, thereby maximizing resource utilization and achieving harmless and high-value comprehensive resource utilization. After the iron is fully collected, the amount of residue that needs to be landfilled is reduced, thereby saving landfill, a non-renewable resource that occupies natural resources.

[0013] Figure 2 This is a schematic diagram of the structure of a support platform with a U-shaped small iron collection tank in the device of the utility model;

[0015] Example 1

[0016] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] like Figure 1 As shown, the length of the oblong tube body 1 is 130 cm and the diameter is 4 cm; the magnetic magnet disks 2 to 11 are symmetrically arranged in pairs along the arc direction of the oblong tube body 1, and their axial length along the oblong tube body 1 is 15 cm, and the axial spacing is 5 cm; their arc width along the oblong tube body 1 is 5 cm; a rubber handle 12 is provided at one end of the oblong tube body 1, and the rubber handle 12 is formed by wrapping a rubber strip around the outer surface of one end of the oblong tube body 1, and the length of the rubber handle 12 is 25 cm, which is based on the comfort of hand holding; the bracket 13 has a U-shaped small iron collection groove in the middle, and the depth of the collection groove is 8 cm and the width is 6 cm.

[0018] The surface of the embedding opening of the magnetic magnet disk 2-11 into the oblong tube body 1 must be ensured to be flat. When the incineration residue comes out of the incinerator, it is transported to the incineration residue collection tank via a conveyor belt. There will be a collecting device above the conveyor belt to collect large pieces of iron. Before the incineration residue passes through the conveyor belt to the incineration residue collection tank, the portable magnetic magnet for hazardous waste incineration residue of the utility model is held by hand and stirred back and forth in the incineration residue to make small pieces of iron adsorbed on the magnetic magnet disk 2-11. When the magnetic magnet disk 2-11 is full of small pieces of iron, the magnetic magnet is pulled back and forth in the U-shaped small piece iron collection groove of the bracket 13 by hand, and the small pieces of iron fall off and can be collected.

[0019] The portable iron-absorbing device for hazardous waste incineration residues of the utility model can also be directly horizontally mounted on the baffles on both sides of the incineration residue conveyor belt, and placed about 8 cm above the incineration residue. It can absorb small pieces of iron in the incineration residue on the conveyor belt by itself. When the iron-absorbing disks 2 to 11 are full of small pieces of iron, the handheld iron-absorbing device is pulled back and forth in the U-shaped small piece of iron collection groove of the bracket 13, and the small pieces of iron fall off and can be collected.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent replacements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
