[0002] The main chemical components of sludge and cement raw materials are the same, the sludge can be used as auxiliary fuel in cement clinker calcination and can partially replace clay raw materials by using the "waste heat drying + cement kiln co-combustion" process, which reduces the damage to farmland in cement production, and the organic and inorganic components in the sludge can be fully utilized by using the cement kiln co-combustion process, the organic components generate heat during calcination in the cement kiln, and the inorganic components are finally converted into cement products.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further described in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] For example, Figs. 1-3The utility model provides a new sludge treatment device based on cement kiln, including base 11, the upper portion of base 11 is installed with combustion device 12, the upper portion of combustion device 12 is installed with cement kiln 13, and the inner chamber of cement kiln 13 is provided with sintering kiln 14, and the upper portion of sintering kiln 14 is installed with the feed end seat 15 of the penetration of the outside of cement kiln 13, and the top is installed with the discharge end seat 16 of the penetration of cement kiln 13,

[0023] The turnover mechanism includes a motor 31 mounted in the middle of the sintering kiln 14, and the output end of the motor 31 is installed with a rotating shaft 32 penetrating into the inner chamber of the sintering kiln 14. The outer wall of the rotating shaft 32 is sleeved with a turntable 33.

[0024] The cage mechanism includes a cage 41 clamped between two turntables 33, and a sintering bin 42 is clamped on the cage 41. One end of the sintering bin 42 is installed with a gap opening sealing plate 43, and several partition rods 44 are installed inside. The upper part of the sintering bin 42 is installed with a ventilation plate 45, and the ventilation plate 45 is provided with a through sieve hole 46.

[0025] It should be noted that one end of the feed end seat 15 penetrating the inner chamber of the sintering kiln 14 is attached to the sealing plate 43. The sludge and cement raw materials are mixed and then transported into the sintering kiln 14 through the feed end seat 15. Compared with the traditional direct combustion method, the sludge and cement raw materials are mixed and then transported into each independent sintering bin 42 through the gap opening on the sealing plate 43, and sintering is carried out in the sintering bin 42.

[0026] In this embodiment, the sintering kiln 14 is improved. Through the cooperation of the turnover mechanism and the cage mechanism, multiple bins are sintered simultaneously. The motor 31 drives the rotating shaft 32 to rotate, thereby driving the turntable 33 and the cage 41 to rotate synchronously. Since the sludge and cement raw materials are mixed and stored in each independent sintering bin 42, the sintering bin 42 has a wide upper part and a narrow lower part, and gaps are left between the partition rods 44 installed inside. This allows sufficient gaps between the sludge and cement raw material mixture to facilitate contact with the heat source. After a period of combustion, the sintering bin 42 can be switched through the rotation of the cage 41, ensuring the full utilization of heat. The sintering effect in each sintering bin is the same, and the rotation process can turn over the sludge and cement raw material mixture. After sufficient combustion, the produced cement can be discharged through the sieve hole 46, facilitating the removal of the sintered product cement.

[0027] It can be understood that the sintering bin 42 is provided with six, respectively installed in each slot of the cage 41. When the cage 41 rotates, the sieve hole 46 on the ventilation plate 45 can be used to conduct heat.

[0028] In order to stably install the sintering kiln 14 in the inner chamber of the cement kiln 13, further, the cement kiln 13 and the sintering kiln 14 are connected through an inner support 2. The inner support 2 includes a horizontal rod part and an inclined rod part arranged in a ring shape.

[0029] It should be understood that the above detailed description of the present application is only intended to illustrate or explain the principles of the present application, and does not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
