Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an intelligent methane exhaust gas discharging device for sewage pipe networks. Background Art

[0002] The sewage pipe network is formed by combining multiple pipes. The pipes range from small to large, and their distribution is similar to a river, showing a dendritic shape, which is completely different from the circulation of the water supply pipe network. The sewage in the sewage pipes contains a large amount of organic matter, which will decompose under the action of anaerobic bacteria. The organic matter will be gradually converted into gases such as methane and carbon dioxide. Methane is an inflammable and explosive gas. If it accumulates in the sewage pipes to a certain concentration and encounters a fire source, it may cause an explosion, posing a great threat to the lives and property safety of people. Therefore, an intelligent methane exhaust gas discharging device for sewage pipe networks is needed to discharge methane.

[0003] The existing intelligent methane exhaust gas discharging devices for sewage pipe networks generally detect the gas in the pipes through gas detectors. When the gas pressure in the pipes is too high or there is too much exhaust gas, the gas inside the sewage pipes is discharged through pressure valves or exhaust valves. When exhausting the sewage pipes, the methane inside the sewage pipes will also be directly discharged. Methane is a combustible greenhouse gas, and direct discharge will not only pollute the environment, affect the ecological balance, but also cause waste of resources. Therefore, we propose an intelligent methane exhaust gas discharging device for sewage pipe networks. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an intelligent methane exhaust gas discharging device for sewage pipe networks.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

A suction pump for accelerating gas flow is arranged at the bottom of the storage device. A second gas pipeline is arranged between the air outlet of the suction pump and the other inclined tee;

[0009] The storage device includes two sealed shells. Two support frames for supporting them are fixed on the outer walls of the two sealed shells. A cavity is formed by inward depression in the middle of the two sealed shells. A detachable positioning cylinder is arranged in the cavity. A plurality of adsorption blocks for adsorbing methane gas are arranged inside the positioning cylinder. A plurality of exhaust holes for facilitating gas discharge are arranged at the bottom of the positioning cylinder;

[0010] A retaining ring is arranged on the lower half section of the positioning cylinder. Two support rods are hinged on the outer wall of the retaining ring.

The bottom of the sealed shell is inserted into the slot. A sealing strip is arranged between the two sealed shells. The sealed shell is limited by the slot of the positioning cylinder to make the two sealed shells in a closed state. By moving the main adjustment block along the sliding groove, the main adjustment block drives the support rod to move, so that the support rod changes from a vertical state to an inclined state, the support rod drives the positioning cylinder to move downward, and the positioning cylinder is separated from the sealed shell.

[0011] As a preferred technical solution of the present invention, a secondary adjustment block is fixed at the bottom of the support rod. A rotatable transmission rod is arranged on the fixed plate. A threaded portion is arranged on the transmission rod. A threaded hole adapted to the threaded portion is formed at the bottom of the main adjustment block. A through hole adapted to the transmission rod is arranged at the bottom of the secondary adjustment block. The bottom of the secondary adjustment block is inserted into the sliding groove, and the two main adjustment blocks are arranged between the two secondary adjustment blocks. By driving the threaded portion to rotate by the transmission rod, the threaded portion is matched with the threaded hole of the main adjustment block, so that the main adjustment block moves along the sliding groove.

[0012] As a preferred technical solution of the present invention, a retractable locking plate is arranged on the secondary adjustment block. A detachable rubber block is arranged at one end of the locking plate. An installation groove for facilitating the movement of the locking plate is arranged at the top of the secondary adjustment block. A wedge block is fixed at one end of the rubber block. A wedge groove adapted to the wedge block is arranged at the end of the locking plate away from the secondary adjustment block. The rubber block is inserted into the wedge groove through the wedge block, so that the rubber block is quickly installed on the locking plate.

[0013] As a preferred technical solution of the present invention, a retractable locking rod is arranged on the secondary adjustment block. A plurality of locking holes adapted to the locking rod are arranged on the locking plate. The bottom of the locking rod penetrates through the secondary adjustment block and is inserted into the locking hole, and a spring is arranged between the locking rod and the secondary adjustment block.

One end of the corrugated pipe away from the conical barrel is connected to the suction port of the air extraction pump.

[0015] As a preferred technical solution of the present invention, a sealing ring is arranged inside the second gas pipeline. A through hole is arranged in the middle of the sealing ring. A plug is arranged in the through hole. A counterweight block is fixed at the bottom of the plug. The lower half of the plug penetrates through the through hole and is fixed to the counterweight block. The weight of the plug can be increased by the counterweight block, so that the center of gravity of the plug is lowered.

[0016] As a preferred technical solution of the present invention, a plurality of fixing grooves are opened on the sealing ring. A plurality of sub-magnets are installed in the fixing grooves, and a main magnet magnetically attracted to the sub-magnets is arranged on the outer wall of the second gas pipeline.

[0017] As a preferred technical solution of the present invention, the plurality of adsorption blocks are respectively made of zeolite, activated carbon and metal-organic framework material, and the arrangement order is that zeolite, activated carbon and metal-organic framework material are stacked downward in sequence.

[0018] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0019] 1. Through the cooperation of structures such as the storage device, the sealing shell, the positioning cylinder, the support rod, the main adjustment block, the sub-adjustment block and the adsorption block, the methane in the gas is adsorbed by the plurality of adsorption blocks of different types. Then, the two sealing shells are separated, the adsorption blocks are taken out of the positioning cylinder, and the adsorption blocks are collected and processed uniformly, so that the methane in the sewage pipeline can be collected, the environment can be protected, the ecological balance can be promoted, and the reasonable utilization of resources can be realized.

[0020] 2. By pulling the lock rod, after the lock rod moves to the outside of the lock groove of the rubber block, the rubber block is pulled, so that the rubber block drives the lock plate to move. After the lock plate moves to the outside of the sub-adjustment block, by adjusting the length of the lock plate extending to the outside of the sub-adjustment block, the distance between the lock plate and the main adjustment block is adjusted, so that the main adjustment block pushes the sub-adjustment block to move through the lock plate, thereby adjusting the distance between the positioning cylinder and the sealing shell, facilitating people to assemble the sealing shells and positioning cylinders of different heights, and improving the convenience of the device.

[0021] 3. By the gas pushing the plug to move upward, after the plug moves above the sealing ring, the gas re-enters the inside of the sewage pipe body through the through hole of the sealing ring. A one-way valve is formed by the cooperation of the plug and the through hole of the sealing ring, so that the gas pressure inside the sewage pipe body is kept moderate, gas backflow is prevented, and the normal use of the device is guaranteed.

[0022] 4. By pushing the main magnet to move along the outer wall of the second gas pipeline, the main magnet drives the sealing ring to move through the sub-magnet magnetically attracted to it, so that the sealing ring moves along the inner wall of the second gas pipeline. This not only facilitates people to adjust the position of the sealing ring, but also facilitates taking out the sealing ring from the second gas pipeline for maintenance and replacement.

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them.

[0036] As can be seen from the above, during use, when there is too much gas inside the sewage pipe body 1, the gas inside the sewage pipe body 1 is monitored by the gas detector 3. When the pressure of the gas reaches the pre-threshold value of the gas detector 3, the gas inside the sewage pipe body 1 is discharged through the exhaust valve.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in and, a first gas pipeline 5 for transporting gas is arranged on one of the inclined tees 2.

[0038] The storage device 4 includes two sealed shells 401. Two support frames 402 for supporting them are fixed on the outer walls of the two sealed shells 401. And the middle parts of the two sealed shells 401 are recessed inward to form a cavity. A detachable positioning cylinder 403 is arranged in the cavity. A plurality of adsorption blocks 411 for adsorbing methane gas are arranged inside the positioning cylinder 403. A plurality of exhaust holes for facilitating gas discharge are arranged at the bottom of the positioning cylinder 403;

[0039] A retaining ring is arranged on the lower half of the positioning cylinder 403. Two support rods 406 are hinged on the outer wall of the retaining ring. Two main adjusting blocks 407 are hinged at the bottoms of the two support rods 406. A fixing plate 405 is arranged between the two main adjusting blocks 407. A chute adapted to the main adjusting block 407 is arranged on the fixing plate 405. A slot adapted to the sealed shell 401 is opened on the retaining ring. The bottom of the sealed shell 401 is inserted into the slot. A sealing strip 410 is arranged between the two sealed shells 401. The sealed shell 401 is limited by the slot of the positioning cylinder 403 to make the two sealed shells 401 in a closed state. By moving the main adjusting block 407 along the chute, the main adjusting block 407 drives the support rod 406 to move, so that the support rod 406 changes from a vertical state to an inclined state, the support rod 406 drives the positioning cylinder 403 to move downward, and the positioning cylinder 403 is separated from the sealed shell 401.

[0040] A secondary adjustment block 408 is fixed to the bottom of the support rod 406. A rotatable transmission rod 417 is provided on the fixed plate 405.

A through hole adapted to the transmission rod 417 is provided at the bottom of the secondary adjustment block 408. The bottom of the secondary adjustment block 408 is inserted into the sliding groove, and the two main adjustment blocks 407 are arranged between the two secondary adjustment blocks 408. By driving the threaded portion of the transmission rod 417 to rotate, the threaded portion is engaged with the threaded hole of the main adjustment block 407, so that the main adjustment block 407 moves along the sliding groove.

[0041] A conical barrel 412 is fixed to the bottom of the positioning cylinder 403. A filter plate 413 for filtering gas is arranged inside the conical barrel 412. A corrugated pipe 404 is fixed to the bottom of the conical barrel 412. One end of the corrugated pipe 404 away from the conical barrel 412 is connected to the suction port of the air extraction pump 8.

[0042] The materials of the multiple adsorption blocks 411 are made of zeolite, activated carbon and metal-organic framework materials respectively, and the arrangement order is that zeolite, activated carbon and metal-organic framework materials are stacked downward in sequence.

[0043] By adopting the above technical solutions:

[0044] During use, when discharging the gas inside the sewage pipe body 1, start the air extraction pump 8. The air extraction pump 8 sucks the gas inside the positioning cylinder 403 through the air inlet, so that the gas inside the sewage pipe body 1 enters the positioning cylinder 403 through the inclined tee 2 and the first gas pipeline 5. After the gas flows through the adsorption block 411, the methane in the gas is adsorbed by the multiple adsorption blocks 411 of different types. The filtered gas enters the inside of the conical barrel 412 through the exhaust holes of the positioning cylinder 403. The gas inside the conical barrel 412 flows into the air extraction pump 8 through the corrugated pipe 404 and then enters the inside of the second gas pipeline 6, and then re-enters the inside of the sewage pipe body 1 through the second gas pipeline 6;

[0045] After the gas filtration is completed, rotate the transmission rod 417. The threaded portion of the transmission rod 417 is engaged with the threaded hole of the main adjustment block 407, so that the main adjustment block 407 moves along the sliding groove of the fixed plate 405, so that the main adjustment block 407 drives the support rod 406 to change from a vertical state to an inclined state. The support rod 406 drives the positioning cylinder 403 to move downward, so that the positioning cylinder 403 is separated from the sealing shell 401. At the same time, the main adjustment block 407 contacts the secondary adjustment block 408, so that the main adjustment block 407 pushes the secondary adjustment block 408 to move. The secondary adjustment block 408 drives the sealing shell 401 to move through the support frame 402, so that the two sealing shells 401 are separated, and the adsorption block 411 is taken out of the positioning cylinder 403, and the adsorption block 411 is collected and processed uniformly.

[0046] Secondly, referring to Figure 5 and Figure 6 As shown, a retractable locking plate 409 is provided on the secondary adjusting block 408. One end of the locking plate 409 is provided with a detachable rubber block 414. The top of the secondary adjusting block 408 is provided with an installation groove facilitating the movement of the locking plate 409. One end of the rubber block 414 is fixed with a wedge block. The end of the locking plate 409 away from the secondary adjusting block 408 is provided with a wedge groove adapted to the wedge block. The rubber block 414 is inserted into the wedge groove through the wedge block, so that the rubber block 414 can be quickly installed on the locking plate 409.

[0047] A retractable locking rod 415 is provided on the secondary adjusting block 408. The locking plate 409 is provided with a plurality of locking holes adapted to the locking rod 415. The bottom of the locking rod 415 penetrates through the secondary adjusting block 408 and is inserted into the locking holes, and a spring 416 is provided between the locking rod 415 and the secondary adjusting block 408.

[0048] By adopting the above technical solution:

[0049] During use, pull the locking rod 415. After the locking rod 415 moves to the outside of the locking groove of the rubber block 414, pull the rubber block 414, so that the rubber block 414 drives the locking plate 409 to move. After the locking plate 409 moves to the outside of the secondary adjusting block 408, adjust the length of the locking plate 409 extending outside the secondary adjusting block 408, adjust the distance between the locking plate 409 and the main adjusting block 407, so that the main adjusting block 407 pushes the secondary adjusting block 408 to move through the locking plate 409, thereby adjusting the distance between the positioning cylinder 403 and the sealing shell 401, facilitating people to assemble the sealing shell 401 and the positioning cylinder 403 with different heights, and improving the convenience of the device.

[0050] Again, referring to Figure 7 , Figure 8 and Figure 9 As shown, a sealing ring 11 is provided inside the second air delivery pipe 6. A through hole is provided in the middle of the sealing ring 11. A plug 12 is provided in the through hole. A counterweight block 7 is fixed to the bottom of the plug 12. The lower half of the plug 12 penetrates through the through hole and is fixed to the counterweight block 7. The weight of the plug 12 can be increased through the counterweight block 7, so that the center of gravity of the plug 12 is lowered.

[0051] By adopting the above technical solution:

[0052] During use, when the purified gas enters the inside of the second air delivery pipe 6, the gas pushes the plug 12 to move upward. After the plug 12 moves above the sealing ring 11, the gas re-enters the inside of the sewage pipe body 1 through the through hole of the sealing ring 11. A one-way valve is formed by the cooperation of the plug 12 and the through hole of the sealing ring 11, keeping the gas pressure inside the sewage pipe body 1 moderate, preventing gas backflow, and ensuring the normal use of the device.

[0053] Finally, refer to Figure 7 、 Figure 8 and Figure 9 As shown, a plurality of fixing grooves are formed in the upper part of the sealing ring 11, and a plurality of secondary magnets 9 are installed in the fixing grooves, and a main magnet 10 magnetically attracted to the secondary magnets 9 is arranged on the outer wall of the second air delivery pipe 6.

[0054] By adopting the above technical solutions:

[0055] During use, the main magnet 10 is pushed to move along the outer wall of the second air delivery pipe 6, and the main magnet 10 drives the sealing ring 11 to move through the secondary magnets 9 magnetically attracted to it, so that the sealing ring 11 moves along the inner wall of the second air delivery pipe 6, which not only facilitates people to adjust the position of the sealing ring 11, but also facilitates taking out the sealing ring 11 from the second air delivery pipe 6 for maintenance and replacement.

[0056] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
