Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] like Figures 1 to 4 As shown, this utility model provides a sludge deodorization device for preparing nutrient soil, mainly including a shell 1 and a filter assembly detachably installed in the shell 1. The shell 1 is a cylindrical structure with an open lower end, and a sealing plate 14 is provided at the upper end of the shell 1. An air inlet 11 is provided in the center of the sealing plate 14, and an air outlet 12 is provided on the side wall of the shell 1.

[0036] The filter assembly is installed into the outer casing 1 through the lower port. The filter assembly includes an outer annular cover plate 4, an inner cover plate 5, an activated carbon cylinder 2, and a sponge cylinder 3. The outer annular cover plate 4 is fixed to the lower end of the outer casing 1, and the activated carbon cylinder 2 is positioned between the outer annular cover plate 4 and the sealing plate 14. The inner cover plate 5 is fixed to the center of the outer annular cover plate 4, and the sponge cylinder 3 is fitted inside the activated carbon cylinder 2 and positioned between the inner cover plate 5 and the sealing plate 14.

[0037] Combined Figures 4 to 6 As shown, the outer annular cover plate 4 has an outer stop on its outer periphery. The outer stop of the outer annular cover plate 4 fits into the lower end of the outer shell 1. The outer annular cover plate 4 and the lower end of the outer shell 1 are fixed together by bolts for easy disassembly. The inner periphery of the outer annular cover plate 4 has an inner stop, and the lower side of the sealing plate 14 has an annular positioning groove opposite to the inner stop. The lower end of the activated carbon cylinder 2 is positioned in the inner stop of the outer annular cover plate 4, and the upper end of the activated carbon cylinder 2 is positioned in the positioning groove. An annular cavity 13 is formed between the outer wall of the activated carbon cylinder 2 and the inner wall of the outer shell 1. The air outlet 12 on the outer shell 1 communicates with the annular cavity 13.

[0038] The inner cover plate 5 has an outer stop on its outer periphery. The outer stop of the inner cover plate 5 fits into the inner hole of the outer annular cover plate 4. The inner cover plate 5 and the outer annular cover plate 4 are fixed together by bolts for easy disassembly. A support cylinder 51 is located at the center of the inner cover plate 5. The support cylinder 51 is integrally formed with the inner cover plate 5. The sponge cylinder 3 is fitted onto the support cylinder 51, and the outer wall of the sponge cylinder 3 contacts the inner wall of the activated carbon cylinder 2. Multiple elongated through grooves 511 are evenly distributed around the axis of the support cylinder 51. A limiting ring 52 is fixed to the upper end of the support cylinder 51. The outer diameter of the limiting ring 52 is larger than the outer diameter of the support cylinder 51, initially positioning the sponge cylinder 3. An annular stepped groove is formed at the end of the air inlet 11. The limiting ring 52 abuts against the stepped groove to fix the support cylinder 51 and prevent it from swaying under wind force.

[0039] At work;

[0040] The air generated by sludge treatment enters the support cylinder 51 through the air inlet 11, and then passes through the through groove 511, the sponge cylinder 3, and the activated carbon cylinder 2 in sequence into the annular cavity 13, and finally flows out from the air outlet 12. During this flow process, large particles of impurities are blocked by the sponge cylinder 3 and accumulate in the support cylinder 51. Water vapor in the airflow is absorbed into the sponge cylinder 3, and the air passing through the activated carbon cylinder 2 is deodorized.

[0041] In this embodiment, a sponge tube 3 is used to block moisture and impurities, thereby improving the service life and efficacy of the activated carbon tube 2. The inner cover plate 5 and the outer annular cover plate 4 are independently detachable and can be easily replaced with the sponge tube 3 and the activated carbon tube 2.

[0042] Example 2:

[0043] Based on the above embodiment one, as follows Figures 4 to 6 As shown, in this embodiment, the inner cover plate 5 has a threaded through hole at its center. The threaded through hole is coaxial with the support cylinder 51, and the diameter of the threaded through hole is slightly smaller than the inner diameter of the support cylinder 51. The screw plug 6 is installed in the threaded through hole via a threaded connection. Every certain period of operation, the sludge deodorization device can open the screw plug 6 to clean large particles of impurities inside the support cylinder 51.

[0044] Example 3:

[0045] Based on the above embodiment one, as follows Figures 1 to 4 As shown, in this embodiment, the air inlet pipe 7 is fixed at the air inlet 11. The outer shell 1, the sealing plate 14, and the air inlet pipe 7 are integrally formed. A flange for connecting with the air inlet pipe is welded to the upper end of the air inlet pipe 7. The air outlet pipe 8 is welded at the air outlet 12, and a flange for connecting with the air outlet pipe is welded to the end of the air outlet pipe 8.
