Description

Technical Field

[0001] This utility model relates to the field of rural domestic wastewater treatment technology, and in particular to a rural domestic wastewater treatment device. Background Technology

[0002] With the improvement of farmers' living standards, a contradiction exists in rural areas: the increasing volume of wastewater discharge is coupled with the relatively lagging development of wastewater treatment facilities. The volume of rural domestic wastewater discharge varies at different times and also changes with the seasons. Sources of rural domestic wastewater include kitchen water, bathing water, and washing water. These water uses are scattered, and rural areas lack facilities to collect domestic wastewater. With rainwater runoff, domestic wastewater flows along the surface into rivers, lakes, ditches, ponds, reservoirs, and other surface water bodies, easily causing environmental pollution. Therefore, a device suitable for the characteristics and actual wastewater treatment needs of rural areas is needed to treat wastewater, meet the needs of the rural environment, and achieve the goals of water resource reuse and environmental protection.

[0003] Wastewater treatment equipment typically includes multiple treatment processes. During treatment, sediment and other impurities adhere to the inner walls of corresponding components, requiring periodic cleaning. However, current technology can only clean components of a specific diameter. When the inner diameters of corresponding components differ, or when cleaning different locations is required, cleaning tools must be changed, which is cumbersome and inefficient.

[0025] This application provides a rural domestic wastewater treatment device, referring to... Figure 1 and Figure 2 , Figure 1 A schematic diagram of the processing mechanism 1 is shown. Figure 2A schematic diagram of the cleaning mechanism 2 placed in the first water tank 111 is shown. The rural domestic wastewater treatment device includes a treatment mechanism 1 and a cleaning mechanism 2; wherein, the treatment mechanism 1 includes a first treatment device 11, a second treatment device 12 and a third treatment device 13; the wastewater passes through the first treatment device 11, the second treatment device 12 and the third treatment device 13 in sequence to treat the wastewater; the cleaning mechanism 2 corresponds to the first treatment device 11, and the cleaning mechanism 2 adaptively cleans impurities at different locations inside the corresponding components of the first treatment device 11.

[0026] In this embodiment of the application, the treatment mechanism 1 can be configured to include a first treatment device 11, a second treatment device 12 and a third treatment device 13; the wastewater is treated sequentially by the first treatment device 11, the second treatment device 12 and the third treatment device 13.

[0027] For example, the first treatment device 11, the second treatment device 12 and the third treatment device 13 can be provided with different structures to treat the wastewater accordingly.

[0028] In this embodiment of the application, the cleaning mechanism 2 can be matched with the first processing device 11, and the inner wall of the corresponding component in the first processing device 11 can be cleaned by the cleaning mechanism 2.

[0029] For example, the cleaning mechanism 2 may be provided with an adjustment structure, such as adjusting the distance between the cleaning component in the cleaning mechanism 2 and the inner wall of the first processing device 11, so as to clean different positions of the inner wall of the first processing device 11.

[0030] In the above embodiments, the processing mechanism 1 is provided, which can treat rural domestic wastewater, improve water resource utilization, and protect the environment. The cleaning mechanism 2 is provided, which can adaptively clean impurities at different positions on the inner wall of the first processing device 11, without frequently changing cleaning tools, thus improving work efficiency.

[0031] In some embodiments of this application, such as Figure 1 and Figure 2 As shown. The first treatment device 11 includes a first water tank 111, which is connected to a water inlet pipe 112. Wastewater enters the first water tank 111 through the water inlet pipe 112. The cleaning mechanism 2 includes a housing 21, in which a cleaning component 22 is installed. The cleaning component 22 cleans the inner wall of the first water tank 111.

[0032] For example, the first water tank 111 is wider at the top and narrower at the bottom, that is, it extends from the opening of the first water tank 111 towards the bottom of the tank, and the inner diameter of the first water tank 111 gradually decreases. The first water tank 111 can be buried underground, which not only saves space on the ground, but also facilitates construction.

[0033] In another example, a brick 14 can be installed at the opening of the first water tank 111, and an inlet pipe 112 can be installed between multiple bricks 14, allowing wastewater to enter the first water tank 111 through the inlet pipe 112. A steel grating cover 15 can be installed above the bricks 14 to seal the opening of the first water tank 111, reducing the influence of external factors on the reagents inside the first water tank 111.

[0034] In another example, flocculants or similar substances can be added to the first water tank 111 to form impurities in the wastewater. Some of these impurities can settle to the bottom of the first water tank 111, while others can adhere to different positions on the inner wall of the first water tank 111.

[0035] In the above embodiment, the wastewater is preliminarily treated by the first water tank 111, which is simple in structure and easy to operate.

[0036] In some embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 , Figure 3 The overall structure diagram of cleaning mechanism 2 is shown. Figure 4 The diagram shows the connection structure between the protective shell 24 and the housing 21. Figure 5 A structural diagram of the cleaning assembly 22 is shown. The cleaning assembly 22 includes a bracket 2201, which is connected to the inner bottom surface of the housing 21. A first motor 2202 is mounted on the bracket 2201. The output shaft of the first motor 2202 is connected to a rotating shaft 2213. The rotating shaft 2213 is connected to a first lever 2203 and a second lever 2208. First support blocks 2204 are respectively provided at both ends of the first lever 2203. First support blocks 2204 are connected to first support rods 2205. The first support rods 2205 are inserted into the housing 21 and slidably connected to it. The rod 2205 is connected to the first cleaning component 2206, and the first support block 2204 is provided with a first spring 2207 between it and the inner wall of the housing 21; the two ends of the second lever 2208 are respectively provided with second support blocks 2209, the second support blocks 2209 are connected to the second support rod 2210, the second support rod 2210 is inserted into the housing 21 and the two are slidably connected, the second support rod 2210 is connected to the second cleaning component 2211, and the second support block 2209 is provided with a second spring 2212 between it and the inner wall of the housing 21.

[0037] For example, the axis of the output shaft of the first motor 2202 can extend vertically and be supported by the bracket 2201. The axis of the rotating shaft 2213 can be parallel or nearly parallel to the axis of the output shaft of the first motor 2202. Two first support blocks 2204 can be respectively disposed at both ends of the first lever 2203, that is, one first support block 2204 corresponds to one end of the first lever 2203, and the other first support block 2204 corresponds to the other end of the first lever 2203.

[0038] The first lever 2203 can be connected to a first support block 2204, and the first support block 2204 is connected to a first support rod 2205. The first support rod 2205 is inserted into the housing 21 and can slide on the housing 21. The first support block 2204 is provided with an inclined surface. When the end face of the first lever 2203 is in contact with the inclined surface on the first support block 2204, as the first lever 2203 rotates, the first support rod 2205 can be driven to move horizontally towards or away from the inner wall of the first water cylinder 111.

[0039] Furthermore, the first spring 2207 is sleeved on the first lever 2203. One end of the first spring 2207 is connected to the inner wall of the housing 21, and the other end is connected to the first support block 2204. The first support block 2204 and the first lever 2203 are reset by the first spring 2207.

[0040] In another example, two second support blocks 2209 can be respectively disposed at both ends of the second lever 2208, that is, one second support block 2209 corresponds to one end of the second lever 2208, and the other second support block 2209 corresponds to the other end of the second lever 2208. The second lever 2208 can be provided with a second support block 2209, and the second support block 2209 is connected to a second support rod 2210. The second support rod 2210 is inserted into the housing 21 and can slide on the housing 21. The second support block 2209 is provided with an inclined surface. When the end face of the second lever 2208 and the inclined surface of the second support block 2209 are in contact, as the second lever 2208 rotates, the second support block 2209 can drive the second support rod 2210 to move horizontally towards or away from the inner wall of the first water cylinder 111.

[0041] Furthermore, the second spring 2212 is sleeved on the second lever 2208. One end of the second spring 2212 is connected to the inner wall of the housing 21, and the other end is connected to the second support block 2209. The second support block 2209 and the second lever 2208 are reset by the second spring 2212.

[0042] It is understood that the first cleaning component 2206 and the second cleaning component 2211 can be arranged circumferentially at equal intervals on the outer side of the housing 21, and the first cleaning component 2206 and the second cleaning component 2211 can move simultaneously away from or towards the inner wall of the first water tank 111. The first cleaning component 2206 and the second cleaning component 2211 can be a brush or other parts with cleaning functions.

[0043] It should be explained that the first lever 2203 and the second lever 2208 may not be on the same horizontal plane; that is, there is a gap between the first lever 2203 and the second lever 2208 in the vertical direction. Simultaneously, the contact point between the first support block 2204 and the first lever 2203 can be on the same horizontal plane as the first lever 2203, and the contact point between the second support block 2209 and the second lever 2208 can be on the same horizontal plane as the second lever 2208. This arrangement reduces the probability of interference between the first support block 2204 and the second support block 2209 during movement. This allows the output shaft of the first motor 2202 to rotate in the same direction, or alternate between forward and reverse rotation, to drive the first cleaning component 2206 and the second cleaning component 2211 to operate.

[0044] In the above embodiments, the first cleaning component 2206 and the second cleaning component 2211 can move simultaneously toward the inner wall of the first water tank 111 or away from the inner wall of the first water tank 111, so that the first cleaning component 2206 and the second cleaning component 2211 fit into different positions of the inner wall of the first water tank 111, thereby cleaning different positions of the inner wall of the first water tank 111; there is no need to frequently change cleaning tools, and the application range is wide.

[0045] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the housing 21 is connected to a first cover plate 23. The outer wall of the first cover plate 23 is provided with an annular groove, which is not marked in the figure. A protective shell 24 is movably connected in the annular groove. A second motor 25 is installed in the protective shell 24. The output shaft of the second motor 25 is connected to the first cover plate 23. The protective shell 24 is connected to a second cover plate 26.

[0046] For example, the first cover plate 23 can be detachably fixed to the housing 21 by means of bolts or other methods, which facilitates installation and disassembly. An annular groove can be provided on the outer wall of the first cover plate 23, and the protective housing 24 can be connected to the first cover plate 23 through the annular groove, so that the first cover plate 23 can drive the housing 21 to rotate.

[0047] In another example, the output shaft of the second motor 25 can extend vertically and is connected to the first cover plate 23, thereby driving the first cover plate 23 to rotate.

[0048] In another example, the protective housing 24 may be connected to a second cover plate 26, which protects the second motor 25.

[0049] Furthermore, two telescopic rods 27 can be provided on the second cover plate 26. The end of the telescopic rod 27 away from the second cover plate 26 is connected to a support plate 28, and the telescopic rod 27 can extend and retract in the vertical direction. The support plate 28 makes it convenient for the user to hold the cleaning mechanism 2; and the support plate 28 is provided with a slot for easy operation by the user.

[0050] Alternatively, a limiting component can be installed on the telescopic rod 27, which is not shown in the figure. After the first cleaning component 2206 and the second cleaning component 2211 move to the area to be cleaned, the limiting component is driven to the position corresponding to the opening of the first water tank 111 and fixed in that position, thereby fixing the protective shell 24 and the telescopic rod 27 as a whole, which facilitates the operation of the staff and eliminates the need for the staff to hold the support plate 28 for a long time, reducing the workload.

[0051] In the above embodiment, due to the presence of a protective shell 24 and a second motor 25, the second motor 25 drives the first cover plate 23 and the shell 21 to rotate, thereby driving the first cleaning component 2206 and the second cleaning component 2211 on the shell 21 to rotate. The first cleaning component 2206 and the second cleaning component 2211 clean the inner wall of the first water tank 111, reducing the operator's labor intensity and improving work efficiency.

[0052] In some embodiments of this application, such as Figure 1 As shown, the second treatment device 12 includes a second water tank 121. A first connecting pipe 122 is provided between the first water tank 111 and the second water tank 121. One end of the first connecting pipe 122 is provided in the first water tank 111 and the other end is provided in the second water tank 121. A first filler 123 is provided in the second water tank 121 to treat the wastewater in the second water tank 121.

[0053] For example, the second water tank 121 can be buried underground. A standing brick 14 can be installed between the second water tank 121 and the first water tank 111. The first connecting pipe 122 can be installed among multiple standing bricks 14, with the position of the standing brick 14 corresponding to the position of the standing brick 14 located at the opening of the first water tank 111. Furthermore, a steel grating cover 15 can be placed over the standing brick 14 corresponding to the second water tank 121.

[0054] In another example, the first filler 123 can be a porous adsorbent material, bamboo charcoal, broken tiles, etc. An air pump can be installed in the porous adsorbent material or other components. Furthermore, a drive device can be installed in the first water tank 111, and the drive device is connected to the first connecting pipe 122 to facilitate the transfer of wastewater from the first water tank 111 to the second water tank 121 through the first connecting pipe 122.

[0055] In the above embodiment, since a second water tank 121 is provided, the wastewater passing through the first water tank 111 is subjected to biochemical treatment through the second water tank 121 and the first filler 123.

[0056] In some embodiments of this application, such as Figure 1 As shown, the third treatment device 13 includes a third water tank 131, and a second connecting pipe 124 is provided between the third water tank 131 and the second water tank 121. One end of the second connecting pipe 124 is provided in the second water tank 121, and the other end is provided in the third water tank 131. A second filler is provided in the third water tank 131 to treat the wastewater in the third water tank 131.

[0057] For example, a brick 14 can be set at the opening of the third water tank 131, and the second connecting pipe 124 can be installed in the corresponding brick 14. In addition, a water outlet pipe 16 is also installed in the corresponding brick 14 on the third water tank 131, and the wastewater treated by the first water tank 111, the second water tank 121 and the third water tank 131 can flow out through the water outlet pipe 16.

[0058] Drive devices can be installed in the second water tank 121 and the third water tank 131 respectively. The drive device in the second water tank 121 transports wastewater to the third water tank 131 through the second connecting pipe 124. The drive device in the third water tank 131 discharges the treated wastewater to a designated location through the outlet pipe 16.

[0059] In another example, the second filler may include large stones 132, medium stones 133, and coarse sand 134. For instance, large stones 132, with a size of 3-5cm, can be laid at the bottom of the third water tank 131; medium stones 133, with a size of 2-3cm, can be laid on top of the large stones 132; and coarse sand 134, with a size of 3-5mm, can be laid on top of the medium stones 133. The size and thickness of the large stones 132, medium stones 133, and coarse sand 134 can be selected according to the actual situation.

[0060] Furthermore, planting soil can be filled on the coarse sand 134 in the third water tank 131, and green plants 135 can be planted on the planting soil.

[0061] In the above embodiment, since a third water tank 131 and a second filler are provided, the wastewater after being treated by the second water tank 121 is further treated by the second filler to make it meet the standard that can be used normally.

[0062] The following describes the usage process of the rural domestic wastewater treatment device provided in this application. During use:

[0063] S100: First, the wastewater to be treated flows into the first water tank 111 through the inlet pipe 112. After preliminary treatment in the first water tank 111, the wastewater flows into the second water tank 121 through the first connecting pipe 122. After treatment in the second water tank 121, the wastewater flows into the third water tank 131 through the second connecting pipe 124. After treatment, the wastewater in the third water tank 131 is discharged from the outlet pipe 16 to a designated location for reuse.

[0064] S200: During the initial treatment of wastewater in the first water tank 111, sediment and other impurities easily adhere to different locations on the inner wall of the first water tank 111. Since the diameters of different locations on the inner wall of the first water tank 111 are different, a single-sized cleaning tool cannot clean them all. After cleaning the wastewater in the first water tank 111, the user can hold the support plate 28 and place the telescopic rod 27, protective shell 24, and housing 21 into the first water tank 111.

[0065] S300: Adjust the first cleaning component 2206 and the second cleaning component 2211 to the appropriate positions using the telescopic rod 27, start the first motor 2202, the output shaft of the first motor 2202 drives the rotating shaft 2213 to rotate, the rotating shaft 2213 drives the first lever 2203 and the second lever 2208 to rotate, the first lever 2203 can push the first support block 2204 to move, the first support block 2204 drives the first support rod 2205 to move, the first cleaning component 2206 moves towards the inner wall of the first water tank 111 along with the first support rod 2205; at the same time as the first lever 2203 rotates, the second lever 2208 will also rotate with the rotating shaft 2213, the second lever 2208 pushes the second support block 2209 to move, the second support block 2209 drives the second support rod 2210 to move, the second cleaning component 2211 moves towards the inner wall of the first water tank 111 along with the second support rod 2210. This allows the first cleaning component 2206 and the second cleaning component 2211 to fit against the inner wall of the first water tank 111; during this process, the first spring 2207 and the second spring 2212 are stretched. When the first lever 2203 and the first support block 2204 disengage, the first support rod 2205 returns to its original position along with the first spring 2207; when the second lever 2208 and the second support block 2209 disengage, the second support rod 2210 returns to its original position along with the second spring 2212.

[0066] S400: Start the second motor 25. The output shaft of the second motor 25 drives the first cover plate 23 to rotate. The first cover plate 23 drives the housing 21, the first cleaning component 2206, and the second cleaning component 2211 to rotate, thereby cleaning the inner wall of the first water tank 111 through the first cleaning component 2206 and the second cleaning component 2211. When it is necessary to clean other parts of the inner wall of the first water tank 111, the first cleaning component 2206 and the second cleaning component 2211 can be adjusted accordingly.
