Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge treatment device with a deodorizing function. Background Art

[0002] Sludge, a byproduct of wastewater treatment, is an extremely complex, heterogeneous mass composed of organic debris, bacterial cells, inorganic particles, and colloids. Its key characteristics are high moisture content (up to 99% or more), high organic matter content, and the tendency to decompose and odorize. Furthermore, its fine particles, low specific gravity, and colloidal liquid form contribute significantly to its consistency. Sludge is a thick substance somewhere between a liquid and a solid, and contains a significant amount of odor. The primary components of this odor are hydrogen sulfide, ammonia, methane, mercaptans, and hydrocarbon compounds, which are highly irritating and harmful to the human body. Therefore, deodorization is essential during sludge treatment.

[0003] In current sludge deodorization equipment, when adding deodorant to the sludge, the deodorant is difficult to mix with the sludge, resulting in poor deodorization effect, and it is difficult to determine the amount of deodorant to be added according to the amount of sludge. Utility Model Content

[0004] The purpose of the utility model is to provide a sludge treatment device with a deodorizing function to solve the problems raised in the above background technology.

[0008] The upper and lower sides of the central telescopic tube are provided with docking holes for docking with the upper nozzle and the lower nozzle. The inner wall of the central telescopic tube is fixedly connected to a positioning ring, one side of the positioning ring is fixedly connected to a return spring, and the end of the return spring away from the positioning ring is fixedly connected to a central reinforcement rod located on the inner wall of the stirring rod.

[0009] A further improvement of the technical solution of the present utility model is that the bottom end of the central reinforcing rod is fixedly connected to the bottom of the inner wall of the stirring rod, and the top end of the stirring rod is fixedly connected to the output end of the deodorant extraction pump through a pipeline.

[0010] A further improvement of the technical solution of the present invention is that: a gear is fixedly connected to the outer wall of one end of the stirring rod, and the outer wall of the gear is meshed with the output end of the driving device.

[0011] A further improvement of the technical solution of the present utility model is that a positioning sliding groove is provided on the inner wall of the auxiliary spray rod, and a sliding block is fixedly connected to the outer wall of the central telescopic tube.

[0024] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a sludge treatment device with a deodorizing function, comprising a treatment tank body 1, a deodorant extraction pump 4, a driving device 5 and a stirring rod 6. The top of the inner wall of the treatment tank body 1 is rotatably connected to the stirring rod 6 through a connecting shaft 18, and the outer wall of the stirring rod 6 is fixedly connected to an auxiliary spray rod 7.

[0028] An upper nozzle 8 and a lower nozzle 9 are fixedly connected to the upper and lower sides of the auxiliary spray bar 7 respectively, and a central telescopic tube 10 is movably connected to the inner wall of the auxiliary spray bar 7 .

[0029] The upper and lower sides of the central telescopic tube 10 are provided with docking holes 15 for docking with the upper nozzle pipe 8 and the lower nozzle pipe 9. The inner wall of the central telescopic tube 10 is fixedly connected with a positioning ring 12, and one side of the positioning ring 12 is fixedly connected with a return spring 11. When the central telescopic tube 10 moves outward on the inner wall of the auxiliary spray rod 7, the slider 14 slides on the inner wall of the positioning slot 13. When the slider 14 moves to one end of the positioning slot 13, the docking holes 15 on the outer wall of the central telescopic tube 10 are now all connected with the upper nozzle pipe 8 and the lower nozzle pipe 9, and the deodorant is sprayed into the sludge through the upper nozzle pipe 8 and the lower nozzle pipe 9. At the same time, the auxiliary spray rods 7 are distributed in multiple groups, so that the deodorant can be evenly distributed inside the sludge, thereby improving the efficiency and effect of subsequent deodorization.

[0030] The end of the return spring 11 away from the positioning ring 12 is fixedly connected to the central reinforcing rod 16 located on the inner wall of the stirring rod 6. When deodorization is completed and the deodorant extraction pump 4 stops delivering deodorant, the pressure inside the central telescopic tube 10 gradually becomes less than the return force of the return spring 11, and the central telescopic tube 10 is pulled back to its original position by the return spring 11. At the same time, the residual deodorant inside the upper nozzle 8 and the lower nozzle 9 will block the sludge. When the deodorant is delivered again inside the central telescopic tube 10, the residual deodorant inside the upper nozzle 8 and the lower nozzle 9 will be squeezed out.

[0031] The bottom end of the central reinforcing rod 16 is fixedly connected to the bottom of the inner wall of the stirring rod 6, and the top end of the stirring rod 6 is fixedly connected to the output end of the deodorant extraction pump 4 through a pipeline.

[0032] A gear 17 is fixedly connected to the outer wall of one end of the stirring rod 6 , and the outer wall of the gear 17 is engaged with the output end of the driving device 5 .

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Example 1, the present invention provides a technical solution: preferably, a positioning slot 13 is formed on the inner wall of the auxiliary spray boom 7, and a slider 14 is fixedly connected to the outer wall of the central telescopic tube 10. The inner wall of the positioning slot 13 is slidably connected to the outer wall of the slider 14. During the process of filling the deodorant inside the central telescopic tube 10, the pressure increases rapidly in a short period of time, allowing the docking hole 15 to form a stable docking with the upper nozzle 8 and lower nozzle 9 after the central telescopic tube 10 moves to its maximum distance. At the same time, the outward movement of the central telescopic tube 10 expands the stirring range of the auxiliary spray boom 7, thereby improving the uniformity of mixing the sludge and deodorant.

[0035] A sewage inlet pipe 2 is fixedly connected to one side of the treatment tank body 1 close to the top, and a sewage outlet pipe 3 is fixedly connected to one side of the treatment tank body 1 close to the bottom.

[0036] The working principle of the sludge treatment device with deodorization function is described in detail below.

[0037] like Figure 1-5 As shown, when in use, the sludge is transported to the inside of the treatment tank 1 through the sewage inlet pipe 2, and the driving device 5 is started to drive the stirring rod 6 to rotate through the gear 17 on the outer wall of the stirring rod 6 to stir the sludge. At the same time, the deodorant extraction pump 4 is turned on, and the deodorant is extracted from the deodorant storage container by the deodorant extraction pump 4 and then transported to the inside of the central reinforcement rod 16 through the pipeline. The deodorant transported to the inside of the central reinforcement rod 16 enters the central telescopic tube 10 through the auxiliary spray rod 7. As the pressure inside the stirring rod 6 continues to increase, the central telescopic tube 10 moves outward on the inner wall of the auxiliary spray rod 7 under the push of the deodorant, and at the same time pulls the reset spring 11.

[0038] When the central telescopic tube 10 moves outward on the inner wall of the auxiliary spray rod 7, the slider 14 slides on the inner wall of the positioning slot 13. When the slider 14 moves to one end of the positioning slot 13, the docking holes 15 on the outer wall of the central telescopic tube 10 are all connected with the upper nozzle pipe 8 and the lower nozzle pipe 9. The deodorant is sprayed into the sludge through the upper nozzle pipe 8 and the lower nozzle pipe 9. At the same time, the auxiliary spray rods 7 are distributed in multiple groups, so that the deodorant can be evenly distributed inside the sludge, thereby improving the efficiency and effect of subsequent deodorization.

[0039] When the deodorization is completed and the deodorant extraction pump 4 stops delivering the deodorant, the internal pressure of the central telescopic tube 10 gradually becomes smaller than the reset force of the reset spring 11, and the central telescopic tube 10 is reset under the pull of the reset spring 11. At the same time, due to the residual deodorant inside the upper nozzle pipe 8 and the lower nozzle pipe 9, the sludge will be blocked. When the deodorant is re-delivered inside the central telescopic tube 10, the deodorant remaining inside the upper nozzle pipe 8 and the lower nozzle pipe 9 will be squeezed out.

[0040] During the process of filling the deodorant inside the central telescopic tube 10, the pressure increases rapidly in a short period of time, so that the docking hole 15 forms a stable docking with the upper nozzle 8 and the lower nozzle 9 after the central telescopic tube 10 moves to the maximum distance. At the same time, after the central telescopic tube 10 moves outward, the stirring range of the auxiliary spray rod 7 is expanded, thereby improving the mixing uniformity of the sludge and deodorant.

[0041] It should be noted that, in this article, the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or still includes elements that are inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element. The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
