Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medicine spraying devices, in particular to a mobile garbage excavation deodorizing medicine spraying device. Background Art
[0002] During the landfill process, garbage is exposed to an anaerobic environment. Anaerobic microorganisms in the organic matter (such as food scraps) produce a series of gases, including methane (CH4), carbon dioxide (CO2), ammonia (NH3), hydrogen sulfide (H2S), and some volatile organic compounds (VOCs). Gases like ammonia and hydrogen sulfide are the main sources of odor. When the garbage is excavated, these gases are released into the environment, producing a pungent odor and potentially irritating the respiratory system. At high concentrations, they can cause health problems such as poisoning.
[0003] Currently, most landfill deodorization methods include fixed air cannons and curtain walls. While these methods are effective, they also have drawbacks. First, the spraying rate is fixed and cannot be adjusted according to changes in odor concentration, which can lead to insufficient or wasted spray. Second, odor concentrations fluctuate significantly during the different stages of waste excavation, and these deodorization devices often cannot respond quickly enough to these changes, resulting in suboptimal deodorization results.

DETAILED DESCRIPTION
[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.
[0019] like Figure 1-3 The mobile garbage excavation deodorizing agent spraying device shown in the figure includes a raw liquid storage tank 2, which is connected to a solution proportioning pump 1 through a solution pipeline, and the output end of the solution proportioning pump 1 is connected to a dispensing tank 15 through a solution pipeline, and the dispensing tank 15 is connected to a drug delivery pump 14 through a solution pipeline, and the drug delivery pump 14 is connected to a solution storage tank 3 through a solution pipeline, and the solution storage tank 3 is connected to a high-pressure pump 4 through a solution pipeline, and the high-pressure pump 4 is connected to a spray pipeline 19 through a connecting hose, and a plurality of atomizing nozzles 7 are installed on the surface of the spray pipeline 19, and an odor concentration measuring instrument 8 is provided on one side of the atomizing nozzle 7, and a liquid concentration meter 2 is provided inside the dispensing tank 15. 0, the excavator 9 moves to the garbage area and controls the bucket to dig garbage through the excavator boom 10. The excavator boom 10 drives the odor concentration meter 8 and multiple atomizing nozzles 7 to move synchronously. At this time, the odor concentration meter 8 detects the odor concentration in the area. The signal of the odor concentration meter 8 is fed back to the PLC controller. The PLC controller controls the opening of the solution proportioning pump 1 to increase or decrease the amount of deodorizing solvent in the stock liquid storage tank 2 to achieve the concentration of the deodorizing agent after proportioning. Different concentrations of deodorizing agents are proportioned according to the odor concentration range, thereby improving the deodorizing effect and achieving the purpose of saving deodorizing agents. The solution proportioning pump 1 will soften the aqueous solution and the deodorizing agent. The odor-removing agent is sequentially delivered to the dispensing tank 15 for proportioning the deodorizing solvent. The deodorizing solvent is delivered to the solution storage tank 3 via the agent delivery pump 14. The solution storage tank 3 serves as a temporary storage. When the detected odor concentration exceeds or exceeds the concentration range, the deodorizing agent needs to be re-proportioned according to the odor concentration. Therefore, the solution proportioning pump 1 is controlled to stop the circulation of the aqueous solution and the deodorizing solvent to the dispensing tank 15. After all the deodorizing agent in the dispensing tank 15 is delivered to the solution storage tank 3 via the agent delivery pump 14, the aqueous solution and the deodorizing solvent are sequentially delivered to the dispensing tank 15 via the solution proportioning pump 1, and the amount of the deodorizing solvent delivered is controlled to determine the concentration of the deodorizing agent. degree, and the liquid concentration meter 20 is used to detect the concentration of the deodorizing solvent in the deodorizing agent. When the concentration of the deodorizing agent reaches the required level, the liquid concentration meter 20 will feed back the signal to the PLC controller, and the PLC controller will control the solution proportioning pump 1 to stop working. After the deodorizing agent in the solution storage tank 3 is sprayed, the agent delivery pump 14 can deliver all the deodorizing agent in the proportioning tank 15 to the solution storage tank 3, and then the high-pressure pump 4 will deliver the deodorizing agent to the spray pipe 19 through the connecting hose, and finally spray it out from the multiple atomizing nozzles 7. Moreover, the atomizing nozzles 7 have a deodorizing effect on the excavation position synchronously as the excavator boom 10 digs garbage through the bucket.
[0020] The input end of the solution proportioning pump 1 is connected to a softening water device 17 through a solution pipeline. The device can reduce the hardness of water and mainly removes calcium and magnesium ions in the water. It plays a protective role in the containers and solution pipelines in the device and extends the service life. The softening water device 17 and the tap water pipe are controlled by an electromagnetic valve 5 and a manual valve 18 to control the on and off of the aqueous solution in the softening water device 17.
[0021] A liquid level meter 6 is provided inside the raw liquid storage tank 2 , and the liquid level meter 6 is used to detect the amount of deodorizing solvent in the raw liquid storage tank 2 .
[0022] The solution pipeline between the solution proportioning pump 1 and the dispensing tank 15 is connected to a second filter 16 , which is used to filter particulate matter in the aqueous solution and the deodorizing solvent to prevent the particulate matter from accumulating in the atomizing nozzle 7 and causing blockage.
[0023] A check valve 13, a ball valve 12 and a first filter 11 are connected in sequence to the solution pipeline between the agent delivery pump 14 and the solution storage tank 3. The check valve 13 is used to prevent the deodorizing agent from flowing back, while the ball valve 12 is used to control the on / off of the deodorizing agent in the solution pipeline between the agent delivery pump 14 and the solution storage tank 3. The first filter 11 is used to further filter out particulate matter in the deodorizing agent to prevent the particulate matter from accumulating in the atomizing nozzle 7 and causing blockage.
[0024] The odor concentration measuring instrument 8 is connected to the PLC controller via a wire, the PLC controller is connected to an external power supply via a wire, the liquid concentration meter 20 is connected to the PLC controller via a wire, the PLC controller is installed in the cab of the excavator 9 through a box body, and the external power supply is the battery of the excavator 9. The PLC controller is also connected to the solution proportioning pump 1, the high-pressure pump 4 and the drug delivery pump 14 via wires, respectively, to facilitate automatic control of the device.
[0025] Multiple spray pipes 19 and odor concentration measuring instruments 8 are installed at the front end of the excavator boom 10 of the excavator 9. The odor concentration measuring instruments 8 are away from the solution spraying port of the atomizing nozzle 7 to prevent the deodorizing agent from affecting the detection of odor concentration by the odor concentration measuring instrument 8, thereby improving the detection effect of the odor by the odor concentration measuring instrument 8.
[0026] The connection between the connecting hose and the spray pipe 19 is controlled by the electromagnetic valve 5, which is convenient for automatically controlling the on and off of the deodorizing agent.
