Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment device for a garbage transfer vehicle. Background Art

[0002] At present, the sewage on the garbage transfer truck generally only uses a special sewage tank to collect the sewage generated during the compression process, and adopts a sealing structure to prevent sewage leakage. Some garbage transfer trucks are also equipped with a simple filtering structure to perform a simple filtration before the sewage enters the sewage tank to separate solid impurities and reduce the solid content in the sewage tank. When the transfer truck reaches the transfer station, the sewage in the sewage tank is discharged into the sewage pool of the transfer station for unified purification treatment.

[0003] During the garbage squeezing process in the compression type garbage transfer truck, the discharged sewage is often mixed with fiber or granular impurities, forming a paste-like substance with high viscosity, which can easily block the filter components, drainage pipes and drainage holes in the sewage tank installed at the bottom of the filler, affecting the sewage discharge. At this time, maintenance is required. Since the sewage tank is generally installed at the bottom of the filler with bolts and sealing components, the sewage tank needs to be disassembled as a whole, which is troublesome and not conducive to operation. Summary of the invention

At the same time, the high-pressure pump in the electronically controlled agent box is started to send the agent (such as dispersant) into the annular agent pipe, and then into the sewage treatment box by multiple agent branches at high pressure, and enters the sewage. During the transportation process, the vehicle is bumped, and the interception net is driven up and down by the elastic structure to achieve vibration mixing of the sewage and the agent. The agent disperses the viscous paste formed by fiber or granular impurities contained in the sewage. After arriving at the destination, the drain valve on the drain pipe is opened to discharge the sewage treated with the agent.

The high-pressure pump is a submersible pump, which is placed in the reagent area, and the output end of the high-pressure pump is connected to the reagent main pipe 8 by a pipeline (the pipeline passes through the diaphragm and is connected to the lower end of the reagent main pipe 8), and the other end of the reagent main pipe 8 passes through the top wall of the electronic control reagent box 7 and is connected to the annular reagent pipe 5. The annular reagent pipe 5 is embedded in the arc groove at the top of the outer ring wall of the sewage treatment box 1.

During the shaking process, some sewage containing viscous paste substances with high viscosity formed by fiber or granular impurities enters the maintenance slot 1-3 from the frame position of the interception net 3, and then flows into the sewage treatment box 1 through the gap between the bottom of the interception net 3 and the buffer installation groove 1-2, and then collides and shears with the interception net 3 up and down or left and right under the shaking action, so as to further achieve the mixing of sewage and medicine, and the dispersion of paste substances in sewage; the electric control circuits of several electromagnets 12-1 are arranged inside the side wall of the sewage treatment box 1, and finally pass through the side wall of the sewage treatment box 1 and the electric control agent box 7, and are electrically connected to the electric control area in the electric control agent box 7; A spring 12-2, wherein the upper end of the spring 12-2 is connected to the electromagnet 12-1, and the lower end is connected to the iron ring 12-3; Spring 2 12 - 4 , the upper end of the spring 2 12 - 4 is connected to the iron ring 12 - 3 , and the lower end is connected to the limit pressure plate 12 - 5 , and the limit pressure plate 12 - 5 is movably pressed on the mesh part of the interception net 3 .

[0031] Embodiment 1:

[0032] See also Figure 8 As shown, in this embodiment, a sealing end cover 10 is connected to the outlet end of the medicine branch pipe 9 by means of a plurality of springs 11 , and the inner end surface of the sealing end cover 10 is pressed against the outlet of the medicine branch pipe 9 .

[0033] Embodiment 2:

[0034] See also Figure 9-11 As shown, the inner end surface of the sealing end cover 10 in this embodiment is integrally formed with a plurality of guide ribs 16, and the plurality of guide ribs 16 are distributed circumferentially to form a conical structure with the center protruding toward the inside of the medicine branch pipe 9, so as to guide and disperse the sprayed medicine; the outlet end surface of the medicine branch pipe 9 is provided with a plurality of rib embedding grooves 9-1 embedded in cooperation with the guide ribs 16; the outlet end surface of the medicine branch pipe 9 is provided with a plurality of mounting holes 9-2 for embedding supply springs 11 at positions avoiding the rib embedding grooves 9-1.

[0035] When using the present invention, the sewage treatment box 1 is installed to the bottom of the filler by using the installation edge 2, and is sealed and connected by bolts and sealing rings. When the garbage is sent into the compartment and squeezed, the sewage falls into the sewage treatment box 1 from the opening at the bottom of the filler. At the same time, the high-pressure pump in the electronically controlled reagent box 7 is started to send the reagent (such as dispersant) into the annular reagent pipe 5, and then sent into the sewage treatment box 1 by multiple reagent branch pipes 9 under high pressure, and enters the sewage. Under the action of the high-pressure pump, the reagent is discharged from the outlet end of the reagent branch pipe 9. When spraying, the impact force generated overcomes the elastic force of the spring three 11, thereby pushing open the sealing end cover 10 and directly impacting the guide rib 16. After the dispersion and expansion of the guide rib 16, the medicine is sprayed into the sewage in a scattered splashing manner, so that the medicine can have more contact with the sewage. When the medicine is added, the sealing end cover 10 is reclosed to the outlet end of the medicine branch pipe 9 under the elastic force of the spring three 11, which effectively protects the inside of the medicine branch pipe 9 and prevents the sewage from overflowing into the medicine branch pipe 9 due to shaking during the transportation process; During the transportation process, the vehicle bumps and the electromagnet 12-1 is not energized. At this time, the electromagnet 12-1 has no magnetic attraction on the iron ring 12-3, and the spring 12-2 and the spring 2 12-4 are in their respective natural states (i.e., no force is applied). In this state, the limit pressure plate 12-5 is just pressed on the mesh surface of the interception net 3. The limit pressure plate 12-5 is made of silicone material with certain anti-corrosion performance, and its own micro-elastic force is just in contact with the interception net 3, reducing the lateral deviation of the interception net 3; during the driving of the transfer vehicle, the bumps caused by the road to the transfer vehicle will drive the interception net 3 under the action of the spring 1 12-2 and the spring 2 12-4. The sewage and the reagent are vibrated and mixed by shaking up and down, and the reagent disperses the viscous paste formed by fiber or granular impurities contained in the sewage; during the shaking process, the sewage enters the maintenance slot 1-3 from the frame position of the interception net 3, and then flows into the position below the interception net 3 from the gap between the bottom of the interception net 3 and the buffer installation slot 1-2, and then collides and shears with the interception net 3 up and down or left and right under the action of shaking, so as to further achieve the effect of mixing and dispersing; after arriving at the destination, the drain valve on the drain pipe 6 is opened (the installation of the drain valve is a prior art and is not shown in the figure), and the sewage treated with the reagent is discharged; When it is necessary to use clean water to perform rough cleaning on the sewage treatment box 1, the clean water is loaded into the reagent area in the electronically controlled reagent box 7 through the liquid inlet pipe connected to the reagent box 7 (the connection between the two is a conventional technology, not shown in the figure), and the clean water is extracted by a high-pressure pump and sprayed into the sewage treatment box 1, so that the clean water covers the interception net 3. When dumping the transported garbage, the transport vehicle will also generate some vibration force, and the vibration force will also drive the interception net 3 to shake up and down under the action of the elastic structure 12, thereby achieving the stirring of the clean water, so that the clean water flushes the inner wall of the sewage treatment box 1 and the interception net 3, and finally the drain valve on the drain pipe 6 is opened to discharge the garbage; When it is necessary to thoroughly clean the interception net 3, the inspection end cover 4 can be opened and the electromagnet 12-1 can be energized. After the electromagnet 12-1 is magnetized, the magnetic force overcomes the elastic force of the spring 12-2 and magnetically attracts the iron ring 12-3. At this time, the spring 12-3 and the limit pressure plate 12-5 are lifted, and the limit pressure plate 12-5 is separated from the interception net 3. At this time, the interception net 3 can be taken out from the buffer installation groove 1-2 by using the handle 13, and thoroughly cleaned by using an external cleaning device. A high-pressure water spray gun can also be used to spray water from the buffer installation groove 1-2 toward the inner wall of the sewage treatment box 1 to flush and clean the inner wall of the sewage treatment box 1. After the cleaning is completed, the interception net 3 is reinserted into the sewage treatment box 1 from the inspection slot 1-3, and then the power of the electromagnet 12-1 is disconnected, and it loses power and loses magnetism. At this time, the iron ring 12-3 falls from the electromagnet 12-1, and the limit pressure plate 12-5 is pressed onto the mesh surface of the interception net 3 again.

[0036] Compared with the prior art, the present invention has the following beneficial effects: 1. By utilizing the bumps during transportation, the chemicals added to the sewage treatment tank are mixed relatively fully with the sewage, so that the viscous paste formed by the fiber or granular impurities contained in the squeezed sewage is dispersed, the interaction force between the particles is reduced, and the paste is dispersed into fine particles, thereby improving the fluidity of the sewage; 2. The interception net is detachably installed inside the sewage treatment box using an elastic structure, and an inspection end cover is provided to facilitate direct removal and cleaning of the filter assembly, which is convenient for operation; 3. The interception net swings up and down with the elastic structure, and the sewage is sheared and dispersed up and down by the interception net, making the sewage dispersed more thoroughly and avoiding the formation of large particles; 4. The high pressure of the high-pressure pump combined with the sealing end cover with guiding ridges can not only protect the chemical branch pipe from pollution, but also guide the sprayed chemical to disperse into the sewage, increase the contact area with the sewage, and improve the chemical mixing efficiency.

[0037] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
