Description

Technical Field

[0001] The invention belongs to the technical field of sewage drainage, and specifically relates to an integrated buried sewage facility for residue interception, lifting and dumping. Background Art

[0002] In traditional building sewage discharge systems, septic tanks are common pretreatment facilities. As the starting control unit for urban sewage treatment, they rely on the principles of sedimentation and anaerobic fermentation to effectively reduce the content of suspended organic matter in domestic sewage, reduce the operating load of the terminal sewage treatment system, and to a certain extent solve the problem of preliminary treatment of domestic sewage.

[0003] With the continuous improvement of urban sewage collection systems and treatment facilities, the transformation of rainwater and sewage diversion has also been quite large. Gradually, the value of septic tanks is far from being able to balance their many disadvantages, such as large footprint, high maintenance costs, easy production of greenhouse gases such as isomethane and breeding of bacteria, and many explosion safety accidents have occurred in recent years; at the same time, the setting of septic tanks reduces the carbon-nitrogen ratio in sewage, resulting in poor biodegradability at the inlet end of the sewage treatment plant, requiring additional addition or consumption of carbon sources.

[0004] Under the guidance of improving the quality and efficiency of urban domestic sewage treatment, combined with the latest design specifications and standards, the abolition of septic tanks has become an inevitable trend. However, the abolition of septic tanks will transfer pressure to the municipal sewage pipe network system in turn. The floating grease, solid impurities and excrement contained in the sewage are easy to accumulate in the pipe network, resulting in potential blockage risks in the sewage pipe network, and increasing the operation and maintenance costs and cleaning frequency of the municipal sewage pipe network. Therefore, there is great resistance to promoting the abolition of septic tanks in municipal sewage pipe networks in various places, and solutions must be proposed at the source.

[0005] In order to solve the above problems, the present invention proposes an integrated buried sewage facility for residue interception and lifting and dumping to replace the septic tank. Summary of the invention

[0006] The present invention is proposed to solve the problems existing in the prior art, and its purpose is to provide an integrated buried sewage facility for residue interception and lifting and dumping.

[0007] The technical solution of the present invention is: an integrated buried sewage facility for intercepting, lifting and dumping residues. The integrated buried sewage facility for intercepting, lifting and dumping residues is an integrated assembled facility, which is divided into well chamber No. Ⅰ and well chamber No. Ⅱ by a partition wall. The upstream side of well chamber No. Ⅰ is connected with the upstream sewage pipe, and the downstream side of well chamber No. Ⅰ is connected with the municipal sewage pipe. An interception grid mechanism is arranged in well chamber No. Ⅰ, and the interception grid mechanism intercepts the solid residue discharged from the upstream sewage pipe. A lifting guide rail device is arranged in well chamber No. Ⅰ, and the lifting guide rail device lifts and dumps the intercepted solid residue. Well chamber No. Ⅰ and well chamber No. Ⅱ are connected by a slag guide pipe, and the interception grid mechanism sends the solid residue into well chamber No. Ⅱ through the lifting guide rail device and the slag guide pipe.

[0008] Furthermore, the slag guiding pipe is inclined, and the connecting side of the slag guiding pipe and the No. Ⅰ well chamber is higher than the connecting side of the slag guiding pipe and the No. Ⅱ well chamber.

[0009] Furthermore, an air vent is provided on the upper part of the partition wall between well chamber No. Ⅱ and well chamber No. Ⅰ to facilitate gas circulation in the well chamber; a sewage outlet is provided at the bottom of the partition wall, through which the sewage and cleaning water in well chamber No. Ⅱ are discharged into the downstream of well chamber No. Ⅰ, and a stainless steel grille is provided at the sewage outlet to intercept residues of the sewage and cleaning water entering the sewage outlet.

[0010] Furthermore, the intercepting grid mechanism includes a grid basket, and the grid basket realizes residue transportation through a lifting guide rail device arranged in the No. 1 well chamber, and the lifting guide rail device adopts a chain structure.

[0011] Furthermore, a vertical energy dissipation and diversion riser is provided at the inlet end of the upstream sewage pipe, and the outlet of the energy dissipation and diversion riser is located directly above the lowest position of the grille basket.

[0012] Furthermore, inspection manhole covers are provided at the upper ends of the No. Ⅰ and No. Ⅱ well chambers, and the No. Ⅰ and No. Ⅱ well chambers are respectively isolated from the outdoors through the inspection manhole covers, so as to facilitate equipment inspection and cleaning operations.

[0013] Furthermore, a ventilator is provided on the top of the No. 1 well chamber. The ventilator is an exhaust device for removing polluted gases in the No. 1 well chamber and the No. 2 well chamber, maintaining good ventilation conditions in the well and avoiding risks caused by gas accumulation.

[0014] Furthermore, a rotary stirring cutting head is also provided in the No. 1 well chamber. The rotary stirring cutting head is an electrically driven structure, which stirs the sewage in the No. 1 well chamber to accelerate the discharge of sewage in the well downstream and avoid the accumulation of sediment at the bottom of the well.

[0015] Furthermore, the integrated buried sewage facility for residue interception and lifting and dumping is provided with a control cabinet on the ground, which is erected on a concrete foundation and can also be suspended in the dry area on the left side of the partition wall between well chambers No. Ⅰ and No. Ⅱ.

[0016] Furthermore, the control cabinet provides source power and basic control functions for the indoor lifting guide device and rotary stirring and cutting mechanism of Well No. 1.

[0017] The beneficial effects of the present invention are as follows: The present invention can effectively intercept solid residues such as floating objects in domestic sewage and realize automatic lifting and dumping of the intercepted residues. At the same time, a rotary stirring head is provided at the bottom of the well as an auxiliary function, which reduces the risk of blockage of the municipal sewage network by sewage discharge from the building side and ensures the smooth operation of the urban sewage drainage network.

[0018] The present invention can be widely used in the beginning or middle end of an urban sewage pipe network system, involving many fields such as residential areas, commercial centers, industrial parks, urban rail transit, and public municipal pipe network facilities.

[0019] The present invention can not only help to abolish the setting of septic tanks, but also effectively eliminate the risk of blockage of municipal public sewage pipe networks that may be caused by the abolition of septic tanks, and strongly guarantee the smooth operation of urban sewage drainage pipe networks.

[0022] The slag guiding pipe 5 is inclined, with its ends fixed on the partition wall between well chambers No. Ⅰ 1-1 and well chambers No. Ⅱ 1-2, and its starting end connected and fixed on the frame of the lifting guide rail device 12. At the same time, the slag guiding pipe 5 is suspended and fixed by a suspension fixture 5-1. The starting end of the slag guiding pipe 5 is higher than the ending end, making it inclined to facilitate the dumping of residues. The starting end of the slag guiding pipe 5 is an outwardly expanded end to ensure better connection with the basket opening of the grid basket 11.

[0023] A vent hole 29 is provided at the upper part of the partition wall between well chambers II 1-2 and well chambers I 1-1 to facilitate gas circulation in the well chambers; a sewage outlet 6 is provided at the bottom of the partition wall, through which sewage and cleaning water in well chamber II 1-2 are discharged into the downstream of well chamber I 1-1; a stainless steel grille 9 is provided at the sewage outlet 6 to intercept residues of sewage and cleaning water entering the sewage outlet 6.

[0024] The intercepting grid mechanism includes a grid basket 11, and the grid basket 11 realizes residue transportation through a lifting guide rail device 12 arranged in the No. Ⅰ well chamber 1-1, and the lifting guide rail device 12 adopts a chain structure.

[0025] A vertical energy dissipation and diversion riser 3 - 1 is provided at the inlet end of the upstream sewage pipe 3 , and the outlet of the energy dissipation and diversion riser 3 - 1 is located just above the lowest position of the grid basket 11 .

[0026] The upper ends of the No. Ⅰ well chamber 1-1 and the No. Ⅱ well chamber 1-2 are provided with inspection covers 7, and the No. Ⅰ well chamber 1-1 and the No. Ⅱ well chamber 1-2 are respectively isolated from the outdoors through the inspection covers 7, so as to facilitate equipment inspection and cleaning operations.

[0027] A ventilator 10 is provided at the top of the No. 1 well chamber 1-1 to remove polluted gases in the No. 1 well chamber 1-1 and the No. 2 well chamber 1-2, maintain good ventilation conditions in the well, and avoid risks caused by gas accumulation.

[0028] The No. Ⅰ well chamber 1 - 1 is also provided with a rotary stirring cutting head 18 , which is an electrically driven structure and is used to stir the sewage sediment in the No. Ⅰ well chamber 1 - 1 to avoid accumulation at the bottom of the well.

[0029] The integrated buried sewage facility for residue interception and lifting and dumping is provided with a control cabinet 19 on the ground, which is erected on a concrete foundation 20, and can also be suspended in the dry area on the left side of the partition wall between well chambers No. Ⅰ 1-1 and well chambers No. Ⅱ 1-2, and can be flexibly selected according to actual conditions.

[0030] The control cabinet 19 provides source power and basic control functions for the indoor lifting guide rail device 12 and the rotary stirring and cutting mechanism 18 of Well No. 1.

[0031] Specifically, the rotary cutting head 18 rotates rapidly and irregularly to break up the sewage sediments that have settled or solidified at the bottom of the well, ensuring that the sewage remains fluid and flows smoothly into the municipal sewage pipe 4, thereby avoiding the need for maintenance personnel to go down to clean out the well after siltation.

[0032] Specifically, the integrated buried sewage facility for intercepting and lifting and dumping residues is made of prefabricated concrete modules or high modulus polypropylene assemblies, which have good sealing and corrosion resistance stability, low cost, simple installation, and save construction time to a large extent. The entire well body is circular or rectangular in structure, and there is a cushion foundation 2 at the bottom of the well chamber. The cushion foundation 2 is generally made of concrete, and the cushion foundation 2 is used for leveling, installing, fixing the well chamber, and anti-floating fixing.

[0033] Specifically, a maintenance manhole cover 7 is arranged on the top of the well chamber No. Ⅰ 1-1 and the well chamber No. Ⅱ 1-2. The maintenance manhole cover 7 is made of circular ductile iron. Anti-fall plates are arranged at the wellhead positions of the well chamber No. Ⅰ 1-1 and the well chamber No. Ⅱ 1-2.

[0034] Specifically, the No. 1 well chamber 1-1 and No. 2 well chamber 1-2 are provided with maintenance ladders 8 along the sides of the inspection well cover 7. The maintenance ladders 8 are made of ductile iron or stainless steel, which is convenient for operation and maintenance personnel to go down to the well for maintenance work.

[0035] Specifically, the No. Ⅰ well chamber 1 - 1 is connected to the upstream sewage pipe 3 outside the well through the energy dissipation and diversion pipe 3 - 1 , and there is a height difference with the municipal sewage pipe 4 , that is, the upstream sewage pipe 3 is higher than the municipal sewage pipe 4 .

[0036] Specifically, the main function of the No. 2 well chamber 1-2 is to collect solid residues such as suspended matter intercepted from the No. 1 well chamber 1-1, and is connected to the No. 1 well chamber 1-1 through the slag guide pipe 5. The interior of the slag guide pipe 5 is smooth and has a corresponding slope.

[0037] Specifically, the sewage of the No. II well chamber 1-2 and the sewage from regular operation and maintenance flushing are discharged into the No. I well chamber 1-1 through the connected sewage pipe 6, and the stainless steel grid 9 is provided to prevent the residue in the above water from entering the No. I well chamber 1-1.

[0038] Specifically, the suspended matter and other solid residues intercepted daily in the No. Ⅱ well chamber 1-2 are accumulated, and a hook 30 is provided on the side wall of the No. Ⅱ well chamber for collecting sewage bags such as hanging mesh woven bags, which are manually lifted and cleaned regularly. The operation and maintenance personnel can equip a mobile portable small hand-cranked lifting device on the market or a simpler lifting frame with a pulley block for lifting.

[0039] Specifically, a ventilator 10 is provided on the top of the No. 1 well chamber 1-1. The ventilator 10 is an exhaust device for removing polluted gases in the No. 1 well chamber 1-1 and the No. 2 well chamber 1-2, maintaining good ventilation conditions in the well and avoiding risks caused by gas accumulation.

[0040] Specifically, the ventilator 10 includes a ventilation pipe 21 , a photoelectric converter 22 , a micro air pump 23 , an exhaust port 24 , a rain cap 25 , a gas detector 26 , a photovoltaic panel 27 , and a storage battery 28 .

[0041] Specifically, the bottom of the ventilation pipe 21 extends into the No. Ⅰ well chamber 1-1 by 30-50 mm, and a gas detector 26 is provided at the end of the ventilation pipe 21. The gas detector 26 is used to sense the gas concentration or density in the well, and exhaust is exhausted through the micro suction pump 23 when the set threshold is reached.

[0042] Specifically, a columnar portion is provided at the upper end of the ventilation pipe 21, a micro suction pump 23 is provided in the columnar portion, and scattered exhaust ports 24 are formed at the upper end of the columnar portion, and rain shield caps 25 are provided on the exhaust ports 24. The rain shield caps 25 cover the exhaust ports 24, and a circle of grille nets are provided around the open area under the rain shield cap 25 to prevent external insects and rodents from entering.

[0043] Specifically, the top arc surface of the rain cap 25 is provided with arranged photovoltaic panels 27, and the photovoltaic panels 27 are connected to the photoelectric converter 22 circuit. After conversion, the converted energy enters the storage battery 28 for storage, thereby realizing the weak power supply of the gas detector 26 and the micro suction pump 23.

[0044] Specifically, the intercepting grid mechanism inside the No. Ⅰ well chamber 1-1 includes a grid basket 11 and an energy dissipation and diversion vertical pipe 3-1.

[0045] Specifically, the grid basket 11 is installed at the lower part of the energy dissipation and diversion vertical pipe 3-1 in the No. Ⅰ well chamber 1-1. The half arc surface of the grid basket 11 close to the upstream sewage pipe well chamber side is a precision grid basket made of stainless steel and is designed with tiny gaps to effectively intercept floating objects and solid residues in construction sewage, preventing these impurities from directly entering the downstream sewage pipe network and causing blockage.

[0046] Specifically, the half arc surface of the grille basket 11 on one side close to the lifting guide rail device 12 is made of a smooth stainless steel plate, the main purpose of which is to make it easier and smoother to dump the residue when the basket is dumped, and to intercept the residue and prevent it from hanging on the wall.

[0047] Specifically, the lifting guide rail device 12 inside the No. 1 well chamber 1-1 includes two parts: a chain-type electric lifting mechanism and a basket fixing auxiliary structure.

[0048] Specifically, the lifting guide rail device 12 is mainly a lifting and moving device provided for the grid basket 11 to complete the dumping action of impurities in the basket.

[0049] More specifically, Figures 2 to 3 As shown, the chain-type electric lifting mechanism includes a lifting structure component 12-1, a reducer 12-2, a motor 13, a driving wheel 12-3, a driven wheel 12-4, and a traction chain 12-5.

[0050] More specifically, Figures 2 to 3As shown, the basket fixing auxiliary structure includes an auxiliary frame 11-1, a linkage shaft 11-2, a chain fixing component 11-3, a sliding wheel 11-4, a connecting node 11-5, and a hoop component structure 11-6.

[0051] In terms of connection, the basket fixing auxiliary structure is an integral structural part, connected to the lifting structure component 12-1 through the connection node 11-5, and the grid basket 11 is placed on the basket fixing auxiliary structure to achieve synchronous operation with the lifting device.

[0052] The motor 13 provides power for the lifting guide rail device 12. A contact sensor 14 is provided on the inner wall of the No. 1 well chamber 1-1. When the grille basket 11 is located below the energy dissipation and diversion vertical pipe 3-1, the contact sensor 14 contacts the grille basket 11. The contact sensor 14 provides signal feedback for the grille dirt reaching the cleaning capacity. The information is transmitted to the control cabinet 19 to start the motor 13 of the lifting guide rail device. The motor 13 drives the driving wheel 12-3 connected to its main shaft to rotate. Based on the shaft connection, the driven wheel 12-4 rotates synchronously, thereby driving the traction chain 12-5 to move. The preferred traction chain 12-5 is at least a double-row chain. The traction chain 12-5 serves as a power source for the grille basket 11 to climb, thereby realizing the movement of the grille basket 11 along the guide rail in the No. 1 well chamber 1-1, and the dirt is dumped into the slag guide pipe 5.

[0053] As an implementation method, the motor 13 can use a program motor with relatively mature market applications, and the program can be set in advance by calculating the lifting path, operating speed, lifting weight and other conditions. The forward and reverse rotation of the motor controls the rise or fall of the lifting grille basket, and the motor program can also be programmed with instructions to achieve the grille basket repeatedly dumping action 3 times and then reset according to actual operation needs.

[0054] Specifically, the lifting structure component 12-1 in the lifting guide rail device 12 is mainly composed of U-shaped steel and angle steel structure, and its long side is U-shaped steel with a smooth inner wall. The U-shaped steel guides the sliding wheel 11-4 in the basket fixing auxiliary structure to move upward with the chain lifting, that is, while the traction chain 12-5 provides traction, the sliding wheel 11-4 rolls along the U-shaped steel in the lifting structure component 12-1, and its stroke is determined by the shape of the U-shaped steel.

[0055] Specifically, the upper end of the U-shaped steel is a curved structure with a highest point, which is parallel to the dumping mouth. The tangential speed generated by the instantaneous track change and the change in the center of gravity of the basket body are used to throw the grid basket 11 upward. The main purpose of the design here is to better realize the dumping action of the grid basket 11.

[0056] More specifically, a contact sensor 14 is provided in the upstream side of the well chamber No. Ⅰ 1 - 1 , and the contact sensor 14 can sense the grille dirt in the grille basket 11 , and when it senses that the grille dirt reaches 80% of the cleaning capacity, it transmits the information to the control cabinet 19 .

[0057] Specifically, the rotary stirring cutting device includes a motor 13 , a motor protection shell 13 - 1 , a solid content detector 15 , a coupling 16 , a bevel gear 16 - 1 , a transmission shaft 17 , and a rotary stirring cutting head 18 .

[0058] Specifically, the motor 13 provides power for the rotary cutting device. The motor 13 is located below the middle of the well chamber and is installed and fixed against the side wall of the well chamber. The motor protective shell 13-1 provides water immersion protection for the motor 13, and the protection level can reach IP68. The two bevel gears 16-1 form a coupling 16, and the rotation action is completed through the transmission shaft 17.

[0059] Specifically, the rotary cutting head 18 is in the form of a blade, which senses feedback through the solid content sensor 15 and drives the motor 13, so that it rotates rapidly and irregularly to break up the sewage sediment that has settled or solidified at the bottom of the well, ensuring that the sewage remains fluid and flows smoothly into the municipal sewage pipe 4, thereby avoiding the need for operation and maintenance personnel to go down the well to clean it out.

[0060] Specifically, the control cabinet 19 is as follows Figure 3 As shown, if outdoor conditions permit, it can be installed on an outdoor ground concrete foundation 20 to prevent ground water from affecting its normal operation.

[0061] Specifically, the control cabinet 19 is as follows Figure 2 As shown, when used under a municipal road or in a square, if outdoor facilities are not available, the control cabinet 19 can be placed on the inner wall of well chamber 1-1 and hung and fixed, and the control cabinet 19 utilizes the drier transition space on the right side of well chamber 1.

[0062] Specifically, the frequency and power of electricity consumption of the lifting guide rail device 12 and the rotary cutting head 18 are not high, and priority is given to the use of new energy electricity around the facility. Space for battery installation is reserved in the well or ground control cabinet; when the integrated buried sewage facility for residue interception and lifting and dumping is set in a relatively open square or under a road, where it is inconvenient to obtain electricity, a commercially available pole-fixed photovoltaic panel is installed simultaneously to generate electricity and store it in a battery.

[0063] The present invention can effectively intercept solid residues such as floating objects in domestic sewage and realize automatic lifting and dumping of the intercepted residues. At the same time, a rotary stirring head is provided at the bottom of the well as an auxiliary function, which reduces the risk of blockage of the municipal sewage network by sewage discharge from the building side and ensures the smooth operation of the urban sewage drainage network.

[0064] The present invention can be widely used in the beginning or middle end of an urban sewage pipe network system, involving many fields such as residential areas, commercial centers, industrial parks, urban rail transit, and public municipal pipe network facilities.

[0065] The present invention can not only help to abolish the setting of septic tanks, but also effectively eliminate the risk of blockage of municipal public sewage pipe networks that may be caused by the abolition of septic tanks, and strongly guarantee the smooth operation of urban sewage drainage pipe networks.
