Description

Technical Field

[0002] Residential areas in economically developed regions have relatively well-developed pipe networks, through which domestic sewage is transported to sewage treatment facilities for treatment. However, some economically developed regions lack supporting sewage treatment facilities and equipment, and these housing estates are scattered throughout the area. To achieve comprehensive domestic sewage treatment coverage, small-scale sewage treatment equipment must be installed to treat domestic sewage and achieve effective sewage pretreatment.

[0003] In underdeveloped areas, feces are generally treated separately, such as through biogas digesters. This means that the main domestic sewage treated is kitchen water and washing water. Kitchen water often contains a lot of oil and needs to be degreasing. However, the existing photovoltaic-based domestic sewage treatment and purification equipment can only understand the oil content of the sewage input into the water inlet pipe in real time. Secondly, when treating oil, a large amount of flocculant is often added and allowed to flow and mix on its own, resulting in low mixing efficiency and easily leading to excessive addition of flocculant, resulting in waste of resources.

A spiral auger shaft 801 is provided in the mud discharge pipe 8, and the spiral auger shaft 801 is fixedly connected to the power output end of the mud discharge motor 9.

[0052] The sampling and dosing mechanism includes a water pump 6 fixedly mounted on the top of the movable cover 5. The top output end of the water pump 6 is connected to a water outlet pipe seat 601. The water outlet pipe seat 601 is respectively connected to a sampling pipe 602 and a drug filling pipe 603. A drug discharge pipe seat 604 is provided on the top rear side of the movable cover 5, and the drug discharge pipe seat 604 passes through the movable cover 5. A conversion pipe seat 605 is provided on the top front side of the movable cover 5, and the conversion pipe seat 605 passes through the movable cover 5. The conversion pipe seat 605 is connected to the monitoring pipe 202. The drug discharge pipe seat 604 is connected to the drug discharge pipe 604. 06. A drain pipe 607 and a connecting pipe 609 are connected to the conversion pipe seat 605. A connecting pipe 608 is connected between the drain pipe 607 and the drug outlet pipe 606. The connecting pipe 609 is connected to the drug filling pipe 603. The drain pipe 607 and the connecting pipe 608 are both connected to the water inlet end of the water pump 6 through a hose. The sampling tube 602, the drug filling pipe 603, the drug outlet pipe 606 and the drain pipe 607 are all provided with processing solenoid valves. A drug adding port 610 is provided on the top of the movable cover 5, and the drug adding port 610 is located on the left side of the drug discharge pipe seat 604.

[0053] The specific working principle is: sewage is transported to the treatment tank 1 through the sewage pipe 2, and the treated sewage is discharged through the outlet pipe 3. The photovoltaic cover 4 covers the top of the treatment tank 1, and the movable cover 5 is movably plugged into the front side of the photovoltaic cover 4 through the sliding bars on the left and right sides. This facilitates the disassembly and assembly of the movable cover 5. The sewage at different positions deep in the sewage pipe 2 can be sampled through the sampling and dosing mechanism, and flocculants can be added to different positions deep in the sewage pipe 2 for treatment.

[0054] When sampling, first open the processing solenoid valves on the sampling tube 602 and the drain pipe 607, close all other processing solenoid valves, then open the monitoring solenoid valve at the sampling position, and then turn on the water pump 6. The sewage in the sewage pipe 2 enters the monitoring tube 202 through the sampling outlet 203, and then enters the water inlet end of the water pump 6 through the drain pipe 607, and finally is discharged through the sampling tube 602 on the outlet pipe seat 601 at the outlet end of the water pump 6. The sampling tube 602 can be connected to the monitoring room through a pipeline, which can reduce the labor intensity of the sampling operation and realize the sampling work.

[0055] When adding flocculants, the staff can add flocculants to the sewage pipe 2 regularly or after testing and analyzing the water sample. First, open the treatment solenoid valve on the drug outlet pipe 606 connected to the drug discharge pipe seat 604, and at the same time open the treatment solenoid valve on the drug filling pipe 603, close all other treatment solenoid valves, and open the monitoring solenoid valve on the sampling drug outlet 203 where the flocculant needs to be added, so that the flocculant is transported to the connecting pipe 608 through the drug outlet pipe 606 on the drug discharge pipe seat 604, and then enters the water pump 6 through the water inlet end of the water pump 6, and then is output through the drug filling pipe 603 on the water outlet pipe seat 601 at the discharge end of the water pump 6, and is transported to the conversion pipe seat 605 through the connecting pipe 609, and finally is transported to the monitoring pipe 202 through the conversion pipe seat 605. In this way, the flocculant will be discharged through the sampling drug outlet 203 at the position of the opened monitoring solenoid valve, thereby achieving the effect of adding drugs deep in the sewage pipe 2, thereby reducing the possibility of oil pollution accumulating in the sewage pipe.

[0056] The sewage is first filtered in the treatment tank 1, and the debris generated after filtration is discharged through the dredging component. Specifically, the sludge discharge motor 9 drives the spiral auger shaft 801 to rotate, and the spiral auger shaft 801 brings the debris to one end of the drop pipe 10, and finally discharged through the drop pipe 10.

[0057] The photovoltaic panels in the photovoltaic cover 4 convert solar energy, and it is also equipped with relevant power storage, distribution and transmission equipment to provide power for the water pump 6, processing solenoid valve, monitoring solenoid valve, mud discharge motor 9 and drive motor 702, which can save energy and make the device more environmentally friendly.

[0058] Example 2, refer to Figure 3 、 6 , 7, 9 and 10, in this embodiment, in order to solve the problem of unsynchronized addition of sewage and flocculant in existing photovoltaic-based domestic sewage treatment and purification equipment, which easily leads to excessive addition of flocculant, based on the same concept as the above-mentioned embodiment 1, the photovoltaic-based domestic sewage treatment and purification equipment further includes:

[0059] The dosing and mixing mechanism 7 includes a support base 701 fixedly mounted on the top of the photovoltaic cover plate, a drive motor 702 fixedly mounted on the top of the support base 701, a transmission shaft 703 fixedly mounted on the front power output end of the drive motor 702, a rotating arm 704 fixedly mounted on the front side of the transmission shaft 703, a transmission rod 705 fixedly mounted on the end of the front side wall of the rotating arm 704 away from the transmission shaft 703, a lifting block 706 is sleeved on the outside of the transmission rod 705, and the inner cavity length of the lifting block 706 is greater than twice the length of the rotating arm 704, and a lifting shaft 707 is fixedly connected to the bottom of the lifting block 706. The lifting shaft 707 is a rectangular shaft, and a movable groove matching the rectangular shaft is opened on the photovoltaic cover plate 4. The lifting shaft 707 is movably mounted on the photovoltaic cover plate 4 through the movable groove, and the bottom of the lifting shaft 707 extends into the bottom of the photovoltaic cover plate 4.

[0060] A partition 101 is vertically provided in the middle of the inner cavity of the treatment pool 1, and the treatment pool 1 is divided into a mixing pool 102 and a static pool 103 by the partition 101, and the mixing pool 102 is located in front of the static pool 103, the front side of the inner cavity of the treatment pool 1 is fixedly connected with the filter pool 11, the rear side of the filter pool 11 is fixedly connected with the circulating activity groove 12, and the lifting shaft 707 extends into the inner cavity of the circulating activity groove 12, the rear side of the inner cavity of the filter pool 11 is fixedly connected with the medicine groove 13, the inner cavity of the medicine groove 13 is provided with a medicine extraction pipe 1301, and the medicine extraction pipe 1301 is connected to the discharge pipe 1301. The medicine tube seat 604 is connected, and a medicine discharge port 1302 is provided at the bottom of the right side wall of the inner cavity of the medicine groove 13, and the medicine discharge port 1302 is connected to the circulating movable groove 12. The lifting shaft 707 extends into the bottom of one end of the inner cavity of the circulating movable groove 12 and is fixedly connected to a piston 712. The bottom of the piston 712 is fixedly connected to a linkage rod 713. The bottom of the linkage rod 713 is rotatably connected to a pull rod 714. The end of the pull rod 714 away from the linkage rod 713 is rotatably connected to a movable door 715, and the movable door 715 is hinged at the bottom of the right side wall of the filter tank 11.

[0061] A movable opening 1102 is formed at the bottom of the right side wall of the filter tank 11 , and a movable door 715 is hinged to the top of the inner cavity of the movable opening 1102 .

[0062] The specific working principle is: the driving motor 702 drives the rotating arm 704 to rotate around the axis of the transmission shaft 703 through the transmission shaft 703, so that the transmission rod 705 moves in a circle, and the transmission rod 705 moves in the lifting block 706, so that the lifting block 706 drives the lifting shaft 707 to move up and down, and the design of the rectangular parallelepiped shaft can make the lifting shaft 707 only move up and down, and cannot rotate, so as to maintain its working stability. The lifting movement of the lifting shaft 707 drives the piston 712 to move up and down in the circulating activity groove 12. When the piston 712 drops to the lowest point (i.e. Figure 7As shown), the piston 712 will block the discharge port 1302, and the flocculant in the medicine tank 13 will not be discharged into the mixing tank 102. At this time, the linkage rod 713 will press against the movable door 715 through the pull rod 714 to block the movable port 1102, thereby reducing the amount of sewage entering the mixing tank 102. This will give large particles of debris enough time to settle to the bottom of the filter tank 11, and also give the sewage and flocculant enough time to mix. When the piston 712 rises to the highest point (i.e. Figure 9 As shown), the piston 712 will not block the discharge port 1302, and the flocculant in the medicine tank 13 will be discharged into the mixing tank 102 under its own gravity. At this time, the linkage rod 713 pulls the movable door 715 to rotate through the pull rod 714, and the movable port 1102 is opened, and the sewage enters the mixing tank 102 and mixes with the flocculant.

[0063] In the third embodiment, referring to 3, 6, 7, 9 and 10, in order to solve the problem of low mixing efficiency of sewage and flocculant in the existing photovoltaic-based domestic sewage treatment and purification equipment, based on the same concept as the above-mentioned first embodiment, the photovoltaic-based domestic sewage treatment and purification equipment further includes:

[0064] The middle section of the outer wall of the transmission shaft 703 is in the form of a worm 708 structure, and the right side of the worm 708 is meshed with a worm wheel 709. A support arm 710 is fixedly installed on the front side of the support seat 701, and a stirring shaft 711 is rotatably installed on the support arm 710. The worm wheel 709 is fixedly sleeved on the outer wall of the stirring shaft 711, and the bottom of the stirring shaft 711 passes through the photovoltaic cover 4 and extends to the bottom of the treatment tank 1.

[0065] Two sets of stirring blades 716 are fixedly connected to the outer wall of the stirring shaft 711, and both sets of stirring blades 716 are located on the right side of the movable opening 1102. A cleaning blade 717 is fixedly connected to the bottom of the stirring shaft 711, and the bottom of the cleaning blade 717 is in contact with the bottom of the inner cavity of the mixing tank 102. The bottom of the cleaning blade 717 is a soft rubber sheet.

[0066] A connecting hole 104 is provided at the bottom of the partition 101 , through which the mixing pool 102 is connected to the static pool 103 . A buffer tank 105 is fixedly connected to the right side of the partition 101 , and the bottom of the inner cavity of the buffer tank 105 is located below the connecting hole 104 .

[0067] A barrier filter 106 is horizontally fixedly connected to the inner cavity of the static pool 103 , and the barrier filter 106 is located between the bottom of the drain pipe 3 and the top of the buffer tank 105 .

[0068] The specific working principle is as follows: the transmission shaft 703 drives the worm 708 to rotate, the worm 708 drives the worm wheel 709 to rotate, and the worm wheel 709 drives the stirring shaft 711 to rotate, so that the stirring blade 716 mixes the flocculant and the sewage, and the cleaning blade 717 can clean the bottom of the mixing tank 102, reducing the sewage and flocculant from settling to the bottom after mixing, so that it is transported to the static tank 103 through the connecting hole 104 for sedimentation, and the support arm 710 supports the worm 709 so that the worm 709 can maintain relatively stable rotation, and the mixed sewage is first transported to the buffer tank 105 through the connecting hole 104. The buffer tank 105 buffers the sewage and prevents the sewage from directly entering the static tank 103, so that the vortex generated during stirring affects the sewage in the static tank 103, and the blocking filter 106 can block the flocculants in the sewage, so that the flocculants will not be discharged directly through the drain pipe 3 with the sewage.

[0069] Example 4, referring to 7, 8 and 9, in this embodiment, in order to solve the problem that the debris after filtration of the existing photovoltaic-based residential sewage treatment and purification equipment is difficult to discharge, based on the same concept as the above-mentioned embodiment 1, the photovoltaic-based residential sewage treatment and purification equipment further includes:

The mud discharge pipe 8 extends into the inner cavity of the filter tank 11, and a collection port is provided at the top of one end of the mud discharge pipe 8 extending into the inner cavity of the filter tank 11. Two sets of guide plates 1103 are respectively arranged on the left and right sides of the collection port.

[0071] The specific working principle is: the large particles of debris in the sewage are blocked by the filter net 1101, and the blocked large particles of debris fall under the action of their own gravity, and then are guided to the mud discharge pipe 8 through the guide plate 1103, and finally discharged through the mud discharge pipe 8. The sediment in the treatment tank 1 is manually cleaned by opening the photovoltaic cover 4, and when the device in the filter tank 11 fails, the movable cover 5 can be opened separately to maintain the device in the filter tank 11.
