Description

Technical Field

[0001] The utility model relates to garbage disposal, in particular to a negative pressure deodorization system for a garbage transfer station. Background Art

[0002] A garbage transfer station is a transfer station for collecting domestic garbage in a city. Garbage trucks transport the collected garbage to the garbage transfer station for processing. Garbage transfer stations are usually located around cities. Garbage will ferment and produce toxic odors during transportation. The odor in an open garbage transfer station can easily affect the surrounding environment. Therefore, the garbage needs to be deodorized after being transported to the garbage transfer station.

[0003] At present, most garbage transfer stations use the spray deodorization method for deodorization. That is, after the garbage is transported to the transfer station, deodorants are directly sprayed on the surface of the garbage through multiple atomizing nozzles for deodorization. However, due to the stacking of garbage layer by layer and the high density of garbage stacking, it is not easy for the deodorant to completely penetrate into the garbage, and the garbage in the garbage transfer station cannot be thoroughly deodorized.

[0030] Example:

[0031] like Figures 1 to 5As shown, a negative pressure deodorization system for a garbage transfer station includes an aeration cylinder 11, an aeration chamber 12 penetrating the upper end of the aeration cylinder 11 is provided in the aeration cylinder 11, a sealing cover 13 is fixedly connected to the upper end of the aeration chamber 12, a stirring member 14 penetrating and extending into the aeration chamber 12 is provided on the sealing cover 13, a water pump assembly for inputting water mist is provided on the sealing cover 13, an oxygen pipe 15 for inputting oxygen is fixedly connected to the sealing cover 13 on one side close to the water pump assembly, a U-shaped tube 16 is fixedly connected to the lower end of the aeration cylinder 11, and an air inlet pipe 17 for inputting odor is fixedly connected to the aeration cylinder 11 on one side of the U-shaped tube 16;

[0032] In addition, a motor 25 is fixedly connected to the aeration cylinder 11 , and the motor 25 drives the stirring member 14 to rotate and the water pump assembly to operate through a driving assembly.

[0033] The water pump assembly includes a sealing box 22 and a piston disc 21. The specific structure of the water pump assembly is as follows: the sealing box 22 is fixedly connected to the upper end of the sealing cover 13, a movable chamber 29 is provided in the sealing box 22, the piston disc 21 is slidably connected in the movable chamber 29, a transmission shaft 18 is rotatably connected in the movable chamber 29, and the transmission shaft 18 drives the piston disc 21 to reciprocate through the transmission assembly;

[0034] A water inlet pipe 23 connected to the active chamber 29 is fixedly connected to the side surface of one end of the sealing box 22 away from the rotating wheel 19, and a water supply pipe 24 extending into the aeration chamber 12 is connected to the lower side surface of the active chamber 29;

[0035] The water inlet pipe 23 and the water delivery pipe 24 are both provided with a one-way valve. The one-way valve in the water inlet pipe 23 flows in one direction toward the active chamber 29, and the one-way valve in the water delivery pipe 24 flows in one direction toward the aeration chamber 12.

[0036] In addition, the lower end of the water supply pipe 24 is fixedly connected to an atomizing nozzle (not shown in the figure).

[0037] The working principle of the water pump assembly is as follows: water flows into the active chamber 29 through the water inlet pipe 23, and the transmission shaft 18 drives the piston disc 21 to reciprocate in the active chamber 29 through the transmission assembly, thereby pressing the water flow entering the active chamber 29 into the water delivery pipe 24, and the water flow becomes fine water mist after passing through the atomizing nozzle, and after entering the aeration chamber 12, it mixes with oxygen and odor to perform a deodorization reaction.

[0038] The specific structure of the transmission assembly is as follows: the transmission assembly includes a rotating wheel 19 and an eccentric rod 20;

[0039] The rotating wheel 19 is fixedly connected to the lower end of the transmission shaft 18, the eccentric rod 20 is eccentrically hinged to the lower end surface of the rotating wheel 19, the piston disc 21 is hinged to the other end of the eccentric rod 20, and the piston disc 21 is slidably connected in the eccentric rod 20.

[0040] The working principle of the transmission assembly is: the rotating wheel 19 drives the eccentric rod 20 to rotate eccentrically. During the eccentric rotation of the eccentric rod 20, the piston disk 21 hinged to the other end of the eccentric rod 20 is driven to perform reciprocating linear motion in the active chamber 29, thereby pressing the water in the active chamber 29 to flow into the water delivery pipe 24.

[0041] The output shaft of the motor 25 extends to the top of the sealing box 22, and the upper ends of the stirring member 14 and the transmission shaft 18 extend upward to be flush with the output shaft of the motor 25. In addition, the driving assembly includes a synchronous belt 26, and the motor 25 drives the stirring member 14 and the transmission shaft 18 to rotate by means of the synchronous belt 26.

[0042] The stirring member 14 includes a stirring shaft and stirring blades 27 , and each stirring blade 27 is provided with an air hole.

[0043] The stirring blade 27 is driven by the stirring shaft to rotate at a constant speed in the aeration chamber 12, so that the odor, oxygen and water mist are fully mixed and the three are fully reacted. The air holes further stir the flow of the stirring blade 27, and at least two stirring blades 27 are provided (three stirring blades 27 are provided in this embodiment), and are fixed on the stirring shaft at equal angles with the axis of the stirring shaft as the center, so that the mixing effect of odor, oxygen and water mist is better.

[0044] The lower end of the U-shaped tube 16 is fixedly connected with a drain pipe 28 , and the bottom end of the drain pipe 28 is provided with a valve switch.

[0045] It should be noted here that the density of the main harmful components in the odor (such as hydrogen sulfide, ammonia and low-level fatty amines) is less than the density of oxygen. Therefore, the air inlet pipe 17 in this embodiment is installed on the lower side of the aeration chamber 12, and the oxygen pipe 15 is installed on the upper end of the sealing cover 13, so as to promote the full mixing of the odor and oxygen through the density difference between the odor and oxygen.

[0046] When the motor 25 is powered on, it drives the stirring element 14 and the water pump assembly to operate simultaneously through the synchronous belt 26. During this process, the water pump assembly allows water to form water mist through the atomizing nozzle and enter the aeration chamber 12, and is fully mixed with odor and oxygen through the stirring element 14.

[0047] After the reaction is completed, the water mist will gather into waste liquid, which contains the reaction products and residual odor components dissolved in the water, and needs special recovery treatment. After the deodorization is completed, the operator can discharge the waste liquid in the U-shaped tube 16 through the drain pipe 28 for recovery. The deodorized gas enters the fresh air system (not shown in the figure) through the U-shaped tube 16 and is discharged into the air again.

[0048] It should be noted here that the air inlet pipe 17 and the U-shaped tube 16 in the utility model are both connected to the fresh air duct, and the odor enters the air inlet pipe 17 through the exhaust system in the fresh air system. After entering the U-shaped tube 16, the deodorized gas is re-discharged into the garbage transfer station through the air supply system until there is no obvious odor in the garbage transfer station, thereby achieving the purpose of comprehensive deodorization.

[0049] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
