Description

Technical Field

[0001] This application relates to the technical field of domestic waste treatment equipment, and in particular to a sewage treatment equipment for septic tanks in industrial areas. Background Technology

[0002] After filtration, wastewater needs to undergo biological treatment to further degrade the organic matter in the wastewater. Since combustible gases are produced during the degradation process, wastewater treatment equipment is usually buried underground to reduce external impacts. During the process of wastewater being injected into the treatment equipment, due to the certain depth inside the equipment, the wastewater falling from a high place to a low place has a large kinetic energy, which will generate a large impact on the bottom of the treatment equipment. This not only causes a lot of noise, but also consumes the material at the bottom of the wastewater tank at the impact point. Especially for storage structures made of concrete, the damage to the bottom caused by the impact will be more obvious. Summary of the Invention

[0003] The purpose of this application is to provide a sewage treatment device for septic tanks in factory areas that can reduce the noise and impact damage caused by sewage injection.

[0004] To achieve the above objectives, this application provides a wastewater treatment device for a factory septic tank: It includes a sealed cylinder, with end caps fixedly connected to both ends of the sealed cylinder, and a protective cylinder fixedly connected between the two end caps. The sealed cylinder is located inside the protective cylinder. A pipe assembly is connected to both the protective cylinder and the sealed cylinder. The pipe assembly includes a liquid inlet fixedly connected to the sealed cylinder, with its upper end extending outside the protective cylinder. A diversion section is fixedly connected to one end of the liquid inlet inside the sealed cylinder. The diversion section includes a flow-slowing cone, and an inlet channel is formed at the upper end of the flow-slowing cone. The outer surface of the slow-flow cone has an outlet channel communicating with the inlet channel. The end of the outlet channel away from the inlet channel is higher than the end close to the inlet channel, and the end of the outlet channel away from the inlet channel is lower than the upper end of the inlet channel. The bottom of the sealing cylinder has a drain hole. The pipe assembly also includes a drain part fixedly connected to the bottom of the sealing cylinder. The upper end of the drain part completely covers the drain hole. A sensing component is also provided inside the sealing cylinder, which is suitable for sensing the liquid level in the sealing cylinder to detect the liquid level of the sewage in the sealing cylinder and the progress of subsequent biological treatment.

[0005] As a preferred embodiment, the slow-flow cone is a frustum shape with a smaller upper end and a larger lower end. There are several outlet channels, each of which is inclined. These outlet channels are equidistantly arranged around the axis of the inlet channel, so that the liquid flowing out of the slow-flow cone has good uniformity and the liquid flow is fully decelerated and diffused.

[0006] As a preferred embodiment, the lower end of the flow-slowing cone has a support column, and the lower end of the support column is fixedly connected to the inner bottom surface of the sealing cylinder through a base to ensure the stability of the entire flow-dividing section.

[0007] As a preferred embodiment, the base has a flow channel that runs through the upper and lower end faces, and the flow channel is connected to the drain hole to facilitate the discharge of treated sewage into the sealed cylinder.

[0008] As a preferred embodiment, the flow guiding channels are aligned with the drainage holes, and there are several of each. The flow guiding channels and drainage holes are equidistantly arranged around the axis of the support column to improve the discharge efficiency.

[0009] As a preferred embodiment, the top of the sealing cylinder is provided with an insertion hole, and the liquid inlet includes an inner edge tube that passes through the insertion hole. The upper end of the inner edge tube passes through the insertion hole and the protective cylinder and is connected to an upper bend tube for easy connection to an external pipeline.

[0010] As a preferred embodiment, a first valve body is connected between the upper bend and the inner edge pipe, the end of the upper bend has a first pipe joint, and the lower end of the inner edge pipe is fixedly connected to the upper end of the slow-flow cone, forming an internally connected pipe structure.

[0011] As a preferred embodiment, the drainage section includes a funnel fixedly connected to the bottom surface of the sealing cylinder, with the lower end of the funnel located outside the protective cylinder and connected to a lower bend pipe for easy connection to the drainage pipe.

[0012] As a preferred embodiment, a second valve body is connected between the lower bend and the funnel. The second valve body is located outside the protective cylinder, and the end of the lower bend has a second pipe joint to ensure sealing when connected to the drain pipe.

[0013] As a preferred embodiment, the sensing component includes a hydraulic sensor located at the bottom of the sealed cylinder, with a signal line connected to the top of the hydraulic sensor. The top of the sealed cylinder also has a lead hole for the signal line to pass through and connect to the processor outside the protective cylinder.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] (1) By designing a slow-flow cone structure inside the sealed cylinder, the injected sewage first descends and then rises, and finally falls into the sealed cylinder after being reduced and dispersed. This effectively reduces the impact of sewage on the bottom of the sealed cylinder, which not only reduces the noise during the sewage injection process, but also weakens the damage of sewage to the bottom of the sealed cylinder.

[0016] (2) Due to the special loop structure of the inlet and outlet channels inside the slow flow cone, clean water can be injected into the inlet and outlet channels after the sewage is injected. The liquid surface of the clean water in the inlet channel can seal the air between the first valve body, thereby suppressing the upward overflow of the irritating odor generated during the sewage treatment process.

[0030] like Figure 1-8 The wastewater treatment equipment for the septic tank in the factory area shown includes a rectangular sealed cylinder 3 with two open vertical ends. Each open end of the sealed cylinder 3 is fixedly connected to a vertical end cap 2. A protective cylinder 1 is also fixedly connected between the two end caps 2. The protective cylinder 1 is also rectangular and its shape is a proportionally enlarged version of the sealed cylinder 3. The sealed cylinder 3 is completely located inside the protective cylinder 1. The protective cylinder 1 and the sealed cylinder 3 are connected together by a pipe assembly 5, which is the main component for wastewater input and output. The pipe assembly 5 includes an inlet section 510 fixedly connected to the sealed cylinder 3. The upper end of 510 extends outside the protective cylinder 1. In fact, the top of the sealing cylinder 3 will have a plug hole 301. The liquid inlet 510 includes an inner edge tube 511 that passes through the plug hole 301. The upper end of the inner edge tube 511 passes through the plug hole 301 and the protective cylinder 1 and is connected to an upper bend tube 513. A first valve body 512 is connected between the upper bend tube 513 and the inner edge tube 511 to control the on / off state of the upper bend tube 513 and the inner edge tube 511. The end of the upper bend tube 513 has a first pipe connection end 514, which is usually an electric control valve, for connecting to an external sewage supply pipe or gas outlet pipe.

[0031] One end of the liquid inlet 510 located inside the sealing cylinder 3 is fixedly connected to a flow divider 520. The flow divider 520 includes a flow-slowing cone 522. The lower end of the inner tube 511 is fixedly connected to the upper end of the flow-slowing cone 522. It should be noted that the flow-slowing cone 522 is a frustum shape with a smaller upper end and a larger lower end. The upper end of the flow-slowing cone 522 has an inlet channel 523 extending downward along the axis. The outer side of the frustum of the flow-slowing cone 522 has an outlet channel 524 communicating with the inlet channel 523. There are several outlet channels 524, and each outlet channel 524 is inclined. The 24 channels are equidistantly arranged around the axis of the inlet channel 523 to ensure the uniformity of the sewage flowing down along the slow-flow cone 522. In order to effectively buffer the sewage during its descent, the end of the outlet channel 524 away from the inlet channel 523 is higher than the end close to the inlet channel 523, and the upper end of the outlet channel 524 away from the inlet channel 523 is lower than the upper end of the inlet channel 523. In this way, a portion of liquid will be stored in both the inlet channel 523 and the outlet channel 524, which can prevent the odor generated by the sewage in the sealed cylinder 3 from overflowing.

[0032] The lower end of the slow-flow cone 522 has a coaxial support column 521. The lower end of the support column 521 is fixedly connected to the inner bottom surface of the sealing cylinder 3 through the base 525, thereby providing a stable forming effect for the slow-flow cone 522. The bottom of the sealing cylinder 3 is provided with a drain hole 303. The base 525 is provided with a guide channel 526 that runs through the upper and lower end surfaces. The guide channel 526 is connected to the drain hole 303 and is aligned with the drain hole 303. There are several of each of the guide channels 526 and the drain hole 303. These guide channels 526 and drain holes 303 are all equidistantly arranged around the axis of the support column 521, which can improve the discharge efficiency of the post-treated sewage.

[0033] The pipeline assembly 5 also includes a drain section 530 fixedly connected to the bottom of the sealing cylinder 3, used to discharge the treated sewage from the sealing cylinder 3. The upper end of the drain section 530 completely covers the drain hole 303, and the sewage discharged from the drain hole 303 can only enter the drain hole 303. The drain section 530 includes a funnel 531 fixedly connected to the bottom surface of the sealing cylinder 3. The upper opening of the funnel 531 is large and the lower opening is small. The lower end of the funnel 531 is located outside the protective cylinder 1 and connected to the lower bend pipe 532. A second valve body 533 is connected between the lower bend pipe 532 and the funnel 531. It is usually an electrically controlled valve, used to control the on / off state of the lower end of the funnel 531 and the lower bend pipe 532. The second valve body 533 is located outside the protective cylinder 1, which is convenient for disassembly, assembly and maintenance operations. The lower bend pipe 532 has a second pipe connection end 534 at the end, used to connect to an external pipe, so as to transport the treated sewage to the location of the next process.

[0034] The sealed cylinder 3 is also equipped with a sensing component 4 for sensing the liquid level inside the sealed cylinder 3. Specifically, the sensing component 4 includes a hydraulic sensor 402 located at the bottom of the sealed cylinder 3. Since the density of sewage is similar to that of water, the liquid level can be indirectly estimated by sensing the liquid pressure. A signal line 401 is connected to the top of the hydraulic sensor 402. A lead hole 302 is also provided on the top of the sealed cylinder 3. The signal line 401 passes through the lead hole 302 and is electrically connected to the processor outside the protective cylinder 1, thereby transmitting the sensing signal of the hydraulic sensor 402 to the processor.

[0035] Working principle: In the initial state, the first valve body 512 and the second valve body 533 are closed. During liquid injection, the first pipe end 514 is first connected to the exhaust pipe, which is also connected to a vacuum pump. Then, the first valve body 512 and the vacuum pump are opened to extract the high-pressure gas generated in the sealing cylinder 3. After a negative pressure is formed in the sealing cylinder 3, the vacuum pump and the first valve body 512 are closed, the exhaust pipe is removed, and the sewage supply pipe is connected. Then, the first valve body 512 is opened again, and the filtered sewage flows into the inlet channel 523 through the liquid inlet 510. When the sewage level in the inlet channel 523 reaches the upper end of the outlet channel 524, it will flow downward from the upper end of the outlet channel 524 along the outer surface of the slow-flow cone 522. Because the conical outer surface of the slow-flow cone 522 effectively disperses the liquid flow and reduces the pressure... The downward flow of the liquid reduces the impact of the sewage on the bottom of the sealing cylinder 3 during its entry, and also reduces the noise generated by the impact with the sewage already inside the sealing cylinder 3. As the sewage level gradually rises, the original negative pressure state inside the sealing cylinder 3 gradually returns to normal, and the pressure detected by the hydraulic sensor 402 increases. When the pressure detected by the hydraulic sensor 402 reaches the set value, it indicates that the storage capacity inside the sealing cylinder 3 has reached its upper limit. The highest sewage level is not higher than the upper end of the outlet channel 524, so the sewage injection stops, and clean water is injected at one end to flush out the sewage in the inlet channel 523 and outlet channel 524 and replace the sewage to fill the inlet channel 523 and outlet channel 524. Finally, the first valve body 512 is closed to disconnect the sewage supply pipe.

[0036] As the wastewater settles and ferments, the air pressure inside the sealed cylinder 3 increases, exerting downward pressure on the liquid surface. This causes the pressure detected by the hydraulic sensor 402 to increase. When the pressure detected by the hydraulic sensor 402 stops increasing, it indicates that the wastewater treatment is complete, and the second valve body 533 can be opened. Driven by the high air pressure inside the sealed cylinder 3, the treated wastewater will quickly enter the drainage section 530 through the guide channel 526 and the drain hole 303, and finally be discharged from the drainage pipe connected to the second pipe connection 534. The final wastewater will be discharged under its own gravity. After the treated wastewater is completely drained, the second valve body 533 can be closed, awaiting the next round of wastewater injection.
