During the aerobic compost process, a series of pretreatments are first carried out on the collected organic waste to make it more suitable for the aerobic compost process, thereby improving the compost efficiency and quality.

[0003] In some cases, the organic waste is heated by a heating tank, and after heating and cooling, the next step of treatment is carried out. However, the existing heating tank usually uses a water jacket to heat by circulating hot water, which has low heating efficiency and slow heating speed. SUMMARY

[0004] The utility model aims at providing a kind of aerobic compost pretreatment heating tank structure to solve the above-mentioned defects of prior art.

[0005] The utility model realizes the following technical scheme:

[0006] The aerobic compost pretreatment heating tank structure includes a tank body, a distribution sleeve wrapped around the outer wall of the tank body is arranged at both ends of the tank body, a distribution cavity is formed between the distribution sleeve and the outer wall of the tank body, a plurality of heating half-pipes are arranged between the distribution sleeves at both ends, a fluid cavity for steam flow is formed between the heating half-pipes and the outer wall of the tank body, the fluid cavity is communicated with the distribution cavity, a steam inlet is connected to one end of the distribution sleeve, and a steam outlet is connected to the other end of the distribution sleeve.

[0007] Optionally, the fluid cavity is also used for cooling water flow, a cooling water inlet is connected to one end of the distribution sleeve, and a cooling water outlet is connected to the other end of the distribution sleeve.

[0008] Optionally, the cooling water inlet is arranged at the bottom of the distribution sleeve, and the cooling water outlet is arranged at the top of the distribution sleeve.

[0009] Optionally, the steam inlet is arranged at the top of the distribution sleeve, and the steam outlet is arranged at the bottom of the distribution sleeve.

[0010] Optionally, the steam inlet is arranged at the top of the distribution sleeve, and the steam outlet is arranged at the bottom of the distribution sleeve. During cooling, the steam outlet serves as the cooling water inlet, and the steam inlet serves as the cooling water outlet.

[0011] Optionally, the steam inlet and the steam outlet are each provided with two.

[0012] Optionally, the distribution sleeve is made of angle steel by bending, and the end of the angle steel is closed.

[0013] Optionally, a heat insulation cover is provided between the two end distribution sleeves to enclose the heating half-pipe.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, distribution sleeves are set at both ends of the tank, and heating half-pipes are set between the distribution sleeves. A distribution cavity is formed between the distribution sleeves and the outer wall of the tank, and a fluid cavity is formed between the heating half-pipes and the side wall of the tank. The fluid cavity is connected to the distribution cavity. Since the steam inlet and steam outlet are each set on a distribution sleeve, high-temperature steam is introduced from the steam inlet during heating. The high-temperature steam enters the distribution sleeve and then enters the heating half-pipe to heat the organic waste inside the tank. The steam condensate is discharged through the steam outlet. It can be seen that this utility model uses steam heating. Compared with the existing method of heating with hot water through a water jacket, when the steam flows in the heating half-pipe, there is not only heat exchange, but also a large amount of heat is released during the steam condensation process, which can heat the organic waste inside the tank more quickly. The heating efficiency is high and the heating speed is fast. Attached Figure Description

[0022] Example 1

[0023] refer to Figures 1-4The utility model provides an aerobic compost pretreatment heating tank structure, which comprises a tank body 1, distribution sleeves 2 are arranged on both ends of the tank body 1 and wrap outer walls of the tank body 1, and distribution cavities 4 are formed between the distribution sleeves 2 and the outer walls of the tank body 1.

[0024] Alternatively, in the embodiment, the distribution sleeves 2 are directly made of angle steels, which are welded to the outer walls of the tank body 1, and the ends of the angle steels are closed to form the distribution cavities 4. In other embodiments, the distribution sleeves 2 can also have other structures, such as half-pipes made of round pipes or half-pipes made of square pipes.

[0025] A plurality of heating half-pipes 3 are arranged between the distribution sleeves 2, fluid cavities 5 for steam flow are formed between the heating half-pipes 3 and the outer walls of the tank body 1, the fluid cavities 5 are communicated with the distribution cavities 4 (for example, communication holes 201 are arranged on the distribution sleeves 2 corresponding to the heating half-pipes 3), a steam inlet 6 is connected to one of the distribution sleeves 2, and a steam outlet 7 is connected to the other distribution sleeve 2, that is, the steam inlet 6 and the steam outlet 7 are located at both ends of the tank body 1. During heating, high-temperature steam enters the distribution cavities 4 from the distribution sleeve 2 at one end of the tank body 1 and then enters the heating half-pipes 3, so as to heat the organic waste in the tank body 1, and condensed water of the steam is discharged through the steam outlet 7. It can be seen that, compared with the existing water jacket heating mode, the steam not only exchanges heat when flowing in the heating half-pipes 3, but also releases a large amount of heat during condensation, so that the organic waste in the tank body 1 can be heated more quickly, and the heating efficiency and speed are high.

[0026] In the embodiment, the steam inlet 6 is arranged at the top of the distribution sleeve 2, and the steam outlet 7 is arranged at the bottom of the distribution sleeve 2. Meanwhile, the fluid cavities 5 are also used for cooling water flow, that is, the cooling water is used to accelerate cooling in the utility model. During cooling, the steam outlet 7 serves as a cooling water inlet, and the steam inlet 6 serves as a cooling water outlet, that is, the cooling water and the steam share the same path in the utility model, the steam flows upwards and outwards, and the cooling water flows downwards and outwards. Since the density of the steam is smaller than that of the cooling water, the steam and the cooling water can enter the fluid cavities 5 in this way. In addition, in actual application, the steam inlet 6 and the steam outlet 7 can be provided with connecting flanges, so as to facilitate replacement of steam pipelines or cooling water pipelines.

[0027] As an alternative, the steam inlet 6 and the steam outlet 7 are each provided with two, so as to increase the speed of the high-temperature steam and the cooling water into and out of the tank, and to increase the heating and cooling speed. Preferably, one steam inlet 6 is provided at each of the two ports at the top of the distribution sleeve 2, and the steam outlet 7 is provided close to the bottom of the distribution sleeve 2.

[0028] Example 2

[0029] The difference between this example and Example 1 is that the steam inlet and outlet and the cooling water inlet and outlet are not shared, i.e. the steam inlet and outlet and the cooling water inlet and outlet are independent of each other. Similarly, in this example, the cooling water inlet is provided at the bottom of the distribution sleeve 2, the cooling water outlet is provided at the top of the distribution sleeve 2, the steam inlet 6 is provided at the top of the distribution sleeve 2, and the steam outlet 7 is provided at the bottom of the distribution sleeve 2. It will be readily understood that in one of the distribution sleeves 2, the steam inlet 6 is provided at the top and the cooling water inlet is provided at the bottom, and in the other of the distribution sleeves 2, the cooling water outlet is provided at the top and the steam outlet 7 is provided at the bottom. Furthermore, it will be understood that in actual use, appropriate valves should be provided at the steam inlet 6, the steam outlet 7, the cooling water inlet and the cooling water outlet, so as to close the cooling water inlet and outlet when heating, and to close the steam inlet and outlet when cooling.

[0030] Example 3

[0031] Reference Figure 5 and Figure 6 , this example is further optimized on the basis of Example 1. In this example, a heat shield 8 is provided between the two distribution sleeves 2, which wraps the heating half-pipe 3 inside, and the heat shield 8 can reduce heat loss and improve heating effect. In actual use, the heat shield 8 is welded and fixed with the distribution sleeve 2, and the top is closed, forming a closed cavity with the outer wall of the tank body 1.

[0032] The above are only preferred embodiments of the present application, and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
