Description

Technical Field

[0001] The invention belongs to the technical field of sewage, and in particular, the invention relates to an electric mixing system for sewage pipeline waste. Background Art

[0002] Article 3.3.6 of the "Outdoor Drainage Design Standard" GB50014-2021 stipulates that when sewage collection and centralized treatment facilities have been built in towns, septic tanks should not be installed in the diversion drainage system. The explanation of Article 3.3.6 gives the specific reason for this regulation: when sewage treatment facilities have not yet been built, the installation of septic tanks can reduce the impact of domestic sewage on water bodies. With the gradual construction and improvement of sewage facilities in most parts of my country, the installation of septic tanks will reduce the water quality of the sewage treatment plant inlet, which is not conducive to improving the treatment efficiency of the sewage treatment plant. Combined with the text of Article 3.3.6 and its explanation, the standard only considers that the reduction of BOD5 entering the sewage treatment plant after the installation of the septic tank will increase the difficulty of sewage treatment in the sewage treatment plant, but ignores another role of the septic tank, that is, the septic tank can collect solid dirt in the starting section of the sewage pipe at the first time, effectively preventing the risk of the sewage pipe network after the septic tank being blocked by these sticky dirt. In view of this, it is particularly important to develop a system that can prevent the sewage pipe network from being blocked by sticky dirt without reducing the BOD5 concentration entering the sewage treatment plant.

[0003] After the new standard was introduced, there are two approaches to the current outdoor sewage system. One is to directly cancel the septic tank without making any changes to the entire system; the other is to directly cancel the septic tank and set up a screen tank where the septic tank should be set. The first approach is not advisable, as it does not consider the adverse consequences that may be brought to the sewage network after the new standard cancels the septic tank. The second approach seems to have taken measures to prevent blockage in the sewage network after the septic tank is cancelled, but the effect is not good and has serious negative effects. The main reason is that the screen only has a good interception effect on completely solid waste, but has almost no effect on semi-fluid waste with high water content and high plasticity. Most of the waste in the sewage system is the latter. Whether it is an artificial screen or a mechanical screen, it requires manpower to handle the screen residue. A certain number of screen tanks may need to be installed in a project, increasing labor costs. The screen tank is large in size, produces more biogas, and pollutes the environment. Through the above analysis, it is concluded that setting up a screen tank after canceling the septic tank is not an effective measure to prevent blockage in the sewage network.

[0004] The present invention provides a reamer in the well for mixing the inlet and outlet sewage. The energy of the reamer when working is provided by the corresponding motor. The system is automatically controlled by the liquid level in the well. When the internal sewage of the system increases and the water level in the well rises to the starting liquid level of the motor, the two motors are started at the same time to completely crush the sewage into fine particles. The fine particles are suspended in the sewage and discharged into the downstream sewage pipe network with the water flow. The function of the present invention to crush the solid sewage by the reamer is to prevent the existence of large and heavy sewage in the sewage pipe network, so that it is dispersed into fine particles and suspended in the sewage for a long time, and the precipitation phenomenon is prevented; even if precipitation occurs, due to the small mass and large buoyancy of the sediment particles, it can still be washed and quickly discharged downstream after the next sewage arrives, until it is discharged from the sewage pipe network. The present invention only changes the existence form of sewage in the sewage, and does not reduce the content of sewage, so it will not bring difficulties to the secondary biological treatment of the terminal sewage treatment plant. In summary, the present invention can completely solve the pipe network blockage problem caused by the cancellation of the septic tank setting in the sewage pipe network without affecting the normal operation of the subsequent sewage treatment system.

[0023] The electric mixing system for sewage pipeline waste described in the present invention has a well chamber that adopts a modular design and is assembled on site.

[0024] The sewage pipeline waste electric mixing system described in the present invention has a connecting pipe (03) whose length is smaller than the well diameters of the inlet waste mixing well (02) and the outlet waste mixing well (04).

[0025] The sewage pipeline waste electric mixing system described in the present invention has the same diameters of the inlet waste mixing well (02) and the outlet waste mixing well (04), and the same diameters of the connecting pipe (03) as the sewage inlet pipe (01) and the sewage outlet pipe (05).

[0026] The electric sewage mixing system for sewage pipelines described in the present invention comprises a water inlet sewage mixing well cover (06) and a water outlet sewage mixing well cover (07) which are both of a protective and airtight type.

[0028] The sewage pipeline waste electric mixing system described in the present invention comprises a reamer and a transmission shaft (20) for the inlet waste mixing well and a reamer and a transmission shaft (21) for the outlet waste mixing well, wherein the reamer and the transmission shaft are made of rigid metal and are painted with anti-rust paint.

[0030] The sewage pipeline waste electric mixing system described in the present invention has a reamer group of each layer of the reamer of the inlet waste mixing well reamer and the transmission shaft (20) and the outlet waste mixing well reamer and the transmission shaft (21) with an included angle of 90°.

[0032] The electric mixing system for sewage pipeline waste described in the present invention has two working conditions: a standby condition and an operating condition.

[0033] The electric sewage mixing system for sewage pipelines described in the present invention is in a standby state when the sewage pipeline is draining normally. At this time, there is no or less solid sewage at the bottom of the sewage mixing well (02) of the present invention, the inside of the connecting pipe (03), and the bottom of the sewage mixing well (04) of the sewage outlet. While the upstream sewage is discharged downstream in sequence through the sewage inlet pipe (01), the sewage mixing well (02), the connecting pipe (03), the sewage mixing well (04), and the sewage outlet pipe (05), there are two possible destinations for larger sewage: first, larger sewage with a density smaller than water directly floats on the water surface of the sewage mixing well (02); second, larger sewage with a density larger than water directly settles at the bottom of the sewage mixing well (02), the inside of the connecting pipe (03), and the bottom of the sewage mixing well (04). Therefore, the sewage discharged downstream through the present invention contains almost no large pieces of sewage. As the entire sewage system continues to operate, more and more sewage will accumulate on the water surface of the inlet sewage mixing well (02), at the bottom of the inlet sewage mixing well (02), inside the connecting pipe (03), and at the bottom of the outlet sewage mixing well (04) of the present invention, resulting in a continuous decrease in the water flow cross-sectional area in the connecting pipe (03). In order to ensure that the sewage flow rate through the present invention remains unchanged, according to the basic hydraulic formula: Q=AV, it can be seen that the flow rate of the sewage in the connecting pipe (03) gradually increases as the water flow cross-sectional area decreases, and the energy for the increase in flow rate is provided by the continuously increasing water head of the inlet sewage mixing well (02).

[0034] The present invention discloses a sewage pipeline waste electric mixing system, wherein the operating condition occurs when the sewage pipeline is draining abnormally. When the water level in the inlet waste mixing well (02) rises to the starting water level of the inlet waste mixing well motor (16), the pipeline cannot perform normal drainage function due to blockage, and the inlet waste mixing well motor (16) and the outlet waste mixing well motor (17) are started at the same time. The motor drives the inlet waste mixing well reamer and transmission shaft (20) and the outlet waste mixing well reamer and transmission shaft (21) to rotate at high speed, instantly crushing the solid waste inside the present invention. After the large pieces of solid waste are broken up, the previously blocked bottom of the inlet waste mixing well (02), the inside of the connecting pipe (03), and the bottom of the outlet waste mixing well (04) are unobstructed, causing the water level in the inlet waste mixing well (02) to drop rapidly. When the water level drops to the stop level, the inlet waste mixing well motor (16) and the outlet waste mixing well motor (17) stop running at the same time. At this time, the present invention resumes the function of normal drainage and collection of large pieces of solid waste. In particular, when there are large pieces of waste that are difficult to break up inside the present invention, or when the inlet waste mixing well motor (16) and the outlet waste mixing well motor (17) are difficult to rotate due to excessive adhesion of the waste inside the present invention, the function of the present invention will fail, resulting in the continuous rise of the water level in the inlet waste mixing well (02). When the water level rises to the alarm water level, the weak current signal promptly sends an audible and visual alarm to the manned control room, prompting immediate manual processing.

[0035] The sewage pipeline waste electric mixing system described in the present invention, wherein the inlet waste mixing well (02) and its internal structure and equipment are the technical core of the present invention. When the present invention is in operation, the reamer in the inlet waste mixing well (02) plays a leading role in crushing the large pieces of solid waste in the present invention, and the reamer in the outlet waste mixing well (04) plays an auxiliary role in crushing the large pieces of solid waste in the present invention. In addition, the liquid level controller is arranged at an appropriate position in the inlet waste mixing well (02).

[0036] The sewage pipeline waste electric stirring system described in the present invention is only applicable to domestic sewage systems, and is not applicable to sewage and wastewater systems in highly polluting industries such as nuclear power, chemical industry, and electronics.

[0037] The sewage pipeline waste electric mixing system described in the present invention should be installed in an area without personnel flow and open flames, and should be installed upstream of the sewage pipeline network, because methane may overflow from the ventilation pipe.

[0038] The sewage pipeline waste electric stirring system described in the present invention has the following beneficial effects: it effectively solves the problem of sewage pipes without septic tanks being blocked by large pieces of sticky waste. The technical principle of the invention itself is simple and easy to understand. The whole process does not require manual operation, which saves labor costs and does not cause inconvenience to the operation of secondary biological treatment facilities in downstream sewage treatment plants. At the same time, the invention is easy to construct and is convenient for large-scale promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] See also Figure 2 and Figure 3 and Figure 4In this example, the starting water level is 300 mm below the inlet sewage mixing well constraint 02 (11), the alarm water level is 200 mm below the inlet sewage mixing well constraint 02 (11), and the stop water level is 100 mm above the bottom of the sewage inlet pipe (01).

[0076] See also Figure 5 and Figure 6 ,The working conditions of this example are divided into two types: standby condition and running condition.

[0077] See also Figure 5 In this example, the standby condition occurs when the sewage pipe is draining normally. At this time, there is no or less solid waste at the bottom of the inlet sewage mixing well (02), the inside of the connecting pipe (03), and the bottom of the outlet sewage mixing well (04) in this example. While the upstream sewage is discharged downstream through the sewage inlet pipe (01), the inlet sewage mixing well (02), the connecting pipe (03), the outlet sewage mixing well (04), and the sewage outlet pipe (05) in sequence, there are two possible destinations for larger sewage: first, larger sewage with a density smaller than water directly floats on the water surface of the inlet sewage mixing well (02); second, larger sewage with a density larger than water directly settles at the bottom of the inlet sewage mixing well (02), the inside of the connecting pipe (03), and the bottom of the outlet sewage mixing well (04). Therefore, the sewage discharged downstream after this example contains almost no large pieces of sewage. As the entire sewage system continues to operate, more and more sewage will accumulate on the water surface of the inlet sewage mixing well (02), at the bottom of the inlet sewage mixing well (02), inside the connecting pipe (03), and at the bottom of the outlet sewage mixing well (04) in this example, resulting in a continuous decrease in the cross-sectional area of ​​the water flow in the connecting pipe (03). In order to ensure that the sewage flow rate through the example remains unchanged, according to the basic hydraulic formula: Q=AV, it can be seen that the flow rate of the sewage in the connecting pipe (03) gradually increases as the cross-sectional area of ​​the water flow decreases, and the energy for the increase in flow rate is provided by the continuously increasing head of the inlet sewage mixing well (02).

[0078] See also Figure 6In this example, the operating condition occurs when the sewage pipe is drained abnormally. When the water level in the inlet sewage mixing well (02) rises to the starting water level of the inlet sewage mixing well motor (16), the pipe cannot perform normal drainage function due to blockage, and the inlet sewage mixing well motor (16) and the outlet sewage mixing well motor (17) are started at the same time. The motor drives the inlet sewage mixing well reamer and transmission shaft (20) and the outlet sewage mixing well reamer and transmission shaft (21) to rotate at high speed, and instantly crushes the solid sewage inside the present invention. After the large pieces of solid sewage are crushed, the originally blocked bottom of the inlet sewage mixing well (02), the inside of the connecting pipe (03), and the bottom of the outlet sewage mixing well (04) are unobstructed, resulting in the rapid decrease of the water level in the inlet sewage mixing well (02). When the water level drops to the stop liquid level, the inlet sewage mixing well motor (16) and the outlet sewage mixing well motor (17) stop running at the same time. At this time, the present example resumes the function of normal drainage and collection of large solid waste. In particular, when there are large wastes that are difficult to break up inside the present example, or when the inlet waste mixing well motor (16) and the outlet waste mixing well motor (17) are difficult to rotate due to the excessive adhesion of the wastes inside the present example, the present example will fail to function, resulting in the continuous rise of the water level in the inlet waste mixing well (02). When the water level rises to the alarm level, the weak current signal promptly sends an audible and visual alarm to the manned control room, prompting immediate manual processing.

[0079] In this example, the inlet sewage mixing well (02) and its internal structure and equipment are the technical core of this example. When this example is in operation, the reamer in the inlet sewage mixing well (02) plays a leading role in crushing the large pieces of solid sewage in the present invention, and the reamer in the outlet sewage mixing well (04) plays an auxiliary role in crushing the large pieces of solid sewage in the present invention. In addition, a liquid level controller is set at an appropriate position in the inlet sewage mixing well (02).

[0080] This example is only applicable to domestic sewage systems and is not applicable to sewage systems in highly polluting industries such as nuclear power, chemical industry, and electronics.

[0081] In this example, since methane may overflow from the ventilation pipe, this example should be set up in an area with no flow of people and no open flames, and should be set up upstream of the sewage pipe network.

[0082] It is understandable that practitioners in the art can make equivalent substitutions or changes based on the technical solution and concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
