Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a domestic sludge sintering treatment device for a municipal sewage treatment plant. Background Art

[0002] Sewage sludge from municipal sewage treatment plants can be treated by sintering and can usually be used for a variety of purposes. Sintering is an effective sludge treatment technology that reduces the volume, kills pathogenic microorganisms, reduces the organic content, and converts it into a solid substance by treating sludge at high temperatures. The treated sludge can be used for a variety of purposes, such as soil conditioner, building material, landfill cover, etc. In terms of soil improvement, the organic matter and nutrients contained in the sludge can improve the fertility and water retention capacity of the soil, and have a positive effect on agricultural production. As part of building materials, the treated sludge can be used to make bricks, tiles, etc., realizing the reuse of resources.

[0003] There are some efficiency and operational challenges for small-scale sludge sintering equipment. Generally speaking, the sludge is first carried by the frame and then sent into the roasting kiln for high-temperature sintering. However, a major problem faced by the equipment is how to control the thickness of the sludge. If the sludge layer is too thick, the heat transfer will be affected, resulting in part of the sludge not being heated evenly, thus affecting the sintering effect and quality. Conversely, if the sludge layer is too thin, although it can be heated more evenly, it will lead to low production efficiency because the amount of sludge processed each time is limited. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model proposes a domestic sludge sintering treatment device for a municipal sewage treatment plant, which is convenient for sintering sludge in large quantities and enables both internal and external sludge to be heated.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a domestic sludge sintering treatment device of a municipal sewage treatment plant, comprising:

[0006] A sintering outer frame, the sintering outer frame comprises an upper plate and a lower plate, side plates are connected at both sides between the upper plate and the lower plate, long holes are provided on the upper plate, the lower plate and the side plates, and a baffle is connected to the inner side of the side plate and at the rear end of the lower plate;

[0007] The sintering inner frame is a square frame with a rotating plate on the front side. The sintering inner frame can be stacked and placed in the sintering outer frame. The sintering inner frame is provided with air holes. A square blocking plate is connected to the middle of the rear baffle plate inside the sintering inner frame.

[0008] Furthermore, an embedding area is provided on the upper plate, and a matching raised area is integrally formed on the lower plate.

[0009] Based on the above technical features, the embedded area and the raised area are adapted to each other, so that more devices can be stacked together to further improve production efficiency.

[0010] Furthermore, the upper plate, the lower plate and the side plates are all provided with long holes which are arranged at equal distances.

[0011] Based on the above technical features, the equidistantly arranged long holes can ensure uniform heating, resulting in a better sintering effect.

[0012] Furthermore, there are two types of air holes: circular holes are provided on the baffles on the upper, lower, front and rear sides of the sintered inner frame, and X-shaped holes are provided on the baffles on both sides.

[0013] Based on the above technical features, the ventilation holes ensure that fire can be received in all directions, among which the X-shaped holes can provide a larger fire-receiving area and improve the pressure resistance.

[0014] Furthermore, the thickness of the square baffle plate is half of the height of the inner cavity of the sintered inner frame, and the front of the square baffle plate is flush with the front of the sintered inner frame.

[0015] Based on the above technical features, the square barrier plate is filled in the middle part of the sintering inner frame, which can squeeze the dehydrated sludge to the surrounding areas and avoid the problem of incomplete sintering caused by the sludge in the middle part.

[0016] Furthermore, the rotating plate and the lower end of the sintering inner frame are hinged to each other, and a lock buckle that is mutually engaged is provided between the rotating plate and the sintering inner frame.

[0017] Based on the above technical features, the lock is locked before sintering to prevent sludge from falling.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] Advantages of sintering frame design: The frame structure adopts a porous design to ensure that heat can be evenly transferred to the surface and inside of the sludge. The structure is stable to prevent the sludge from moving or overflowing during the sintering process, ensuring safe operation.

[0020] Optimized design of the inner frame: The inner frame adopts a partition plate and air vent design to promote the uniform distribution of sludge in the inner frame and prevent the occurrence of local overheating or insufficiently heated areas. Reasonable design of loading and unloading mechanism simplifies the sludge treatment process and improves work efficiency.

[0021] Enhanced ventilation and combustion effect: Both the outer frame and the inner frame are equipped with ventilation holes to ensure that hot air and oxygen can effectively enter the combustion area, improve the combustion efficiency and the dehydration effect of the sludge. The hole arrangement allows the sludge to be continuously exposed to high temperature throughout the sintering process, maximizing the use of heat energy and reducing energy consumption.
