Description

Technical Field

[0001] This utility model relates to the field of inclined tube sedimentation technology, and in particular to a multi-bucket non-blocking inclined tube sedimentation device. Background Technology

[0002] In the field of wastewater treatment, secondary sedimentation tanks, as an important component of wastewater treatment systems, are responsible for clarifying the sludge-water mixture formed after biological treatment and for returning activated sludge to the biological treatment stage to maintain the microbial content. In municipal wastewater treatment, traditional secondary sedimentation tanks mainly include horizontal flow sedimentation tanks and radial flow secondary sedimentation tanks. However, with the continuous development of wastewater treatment technology, inclined tube sedimentation tanks have gradually gained attention due to their high efficiency in sludge-water separation and their small footprint.

[0003] However, inclined tube sedimentation tanks face a series of challenges in practical applications. First, due to their adhesiveness, activated sludge easily adheres to the inclined tube packing, causing blockage and affecting effluent quality, preventing it from meeting clarification standards. Second, the temporary sludge hopper in the inclined tube sedimentation tank is also prone to blockage during operation, which not only affects normal sludge discharge but may also adversely impact the overall operating efficiency of the sedimentation tank. Furthermore, the angle of the temporary sludge hopper in the inclined tube sedimentation tank must be greater than or equal to 55° to ensure smooth sludge sliding. When using a single temporary sludge hopper for sludge discharge, the sedimentation tank height is often relatively high to meet this angle requirement, thus increasing civil engineering costs.

[0004] Designing an inclined tube sedimentation device that can solve the problems of clogging of inclined tube packing and temporary sludge hopper, reduce infrastructure costs, and is suitable for small-scale sewage treatment has become an urgent technical challenge in the field of sewage treatment. Utility Model Content

[0005] The purpose of this invention is to provide a multi-hopper non-blocking inclined tube sedimentation device to solve the problems of clogging of inclined tube packing, temporary sludge hopper and sludge discharge pipe in existing inclined tube sedimentation devices.

[0006] This utility model is achieved through the following technical solution:

[0007] A multi-hopper non-clogging inclined tube sedimentation device includes a housing. The bottom of the housing is divided into multiple identical areas. Each identical area is equipped with a temporary sludge hopper with an upper opening the same size as the area. The lower opening of each temporary sludge hopper is connected to a sludge discharge pipe. The sludge discharge pipe exits the device from the bottom and enters an inclined sludge storage hopper located on the upper half of the exit side. The lower end of the inclined sludge storage hopper is connected to a sludge discharge pump via a pipe. The lower end of the sludge discharge pipe exiting the device has an air inlet connected to an air compressor. An inclined tube support is installed above the temporary sludge hopper. An air washing pipe with an upward-facing air inlet is laid under the inclined tube support to declogging the inclined tube packing placed on the inclined tube support. A water distribution channel is located on one side of the inclined tube support, next to a water collection tank. A water outlet weir is located on the other side of the water collection tank.

[0008] Furthermore, each sludge discharge pipe has a sleeve valve installed at the end inside the inclined sludge storage hopper, which can adjust the amount of sludge discharged. The upper end of the sleeve valve passes through the upper end of the inclined sludge storage hopper and is installed on the upper surface. A manual butterfly valve is installed at the upper end of the air inlet at the lower end of the sludge discharge pipe.

[0009] Furthermore, the inclined surface of the sludge hopper faces downwards, and a level gauge is installed on the side of the sludge hopper.

[0010] Furthermore, the width of the inclined tube support is the same as the distance from the water distribution channel to the other side wall of the equipment casing, the length of the inclined tube support is the same as the length of the equipment casing, the area above the inclined tube packing installed on the inclined tube support is the clear water area, and the area between the inclined tube support and the temporary sludge hopper is the water distribution area.

[0011] Furthermore, a water distribution channel is provided at the upper part of the inner shell of the equipment in a direction perpendicular to the inclined sludge storage hopper. A water collection trough of the same length and parallel to the water distribution channel is provided on the upper part of one side of the water distribution channel. Holes leading to the water distribution area are evenly opened at the bottom of the water distribution channel. The upper half of the side of the water collection trough that is not adjacent to the water distribution channel is connected to multiple water outlet weirs.

[0012] Furthermore, the outlet weir is parallel to the bottom of the equipment casing and is evenly distributed on one side of the water collection tank, and the opening of the outlet weir is provided with continuous serrations.

[0013] Furthermore, the outer casing of the equipment and the temporary mud hopper are both made of steel.

[0014] The beneficial effects of this utility model are:

[0015] 1. The bottom of the equipment casing is divided into multiple identical areas, each equipped with a temporary sludge hopper of the same size as the area. This multi-hopper design allows for strict control of the sludge discharge angle, increasing the sludge discharge efficiency and reducing the height of the hoppers, thus lowering infrastructure costs. Simultaneously, the inclined design of the sludge hoppers facilitates smooth sludge flow.

[0016] 2. The equipment is equipped with an air washing pipe. By supplying air to the washing pipe through an air compressor, blockages on the inclined tube packing can be removed, preventing clogging problems caused by the adhesion of activated sludge. At the same time, if the temporary sludge hopper is blocked, air can also be supplied to the air inlet to clear the sludge discharge pipe and the temporary sludge hopper, and each sludge discharge pipe and temporary sludge hopper can be cleared individually.

[0029] Example

[0030] See Figures 1 to 6 :

[0031] A multi-hopper non-clogging inclined tube sedimentation device includes a device housing 1. The bottom of the device housing 1 is divided into multiple identical areas. Each identical area is provided with a temporary sludge hopper 9 with an upper opening the same size as the area. The lower opening of each temporary sludge hopper 9 is connected to a sludge discharge pipe 10. The sludge discharge pipe 10 passes through the bottom of the device and enters an inclined sludge storage hopper 15 located on the upper half of the side of the device. The lower end of the inclined sludge storage hopper 15 is connected to a sludge discharge pump 11 through a pipe. The lower end of the sludge discharge pipe 10 passing through the device has an air inlet 14 connected to an air compressor. An inclined tube support 8 is arranged above the temporary sludge hopper 9. An air washing pipe with an upward air outlet is laid under the inclined tube support 8 to declogging the inclined tube packing 6 placed on the inclined tube support 8. There is a water distribution channel 2 on one side of the inclined tube support 8, and a water collection tank 3 is adjacent to the water distribution channel 2. There is a water outlet weir 4 on the other side of the water collection tank 3.

[0032] The bottom of the equipment casing 1 is divided into several identical areas, each equipped with a temporary sludge hopper 9 of the same size as the area, for temporarily storing concentrated sludge. These temporary sludge hoppers 9 are connected to inclined sludge storage hoppers 15 via sludge discharge pipes 10. The design of the sludge discharge pipes 10 allows gas to enter from the lower air inlet 14 to clear any potential blockages in the pipes and temporary sludge hoppers 9. The inclined design of the inclined sludge storage hoppers 15 facilitates smooth sludge flow and transports the sludge to the anaerobic tank via a sludge discharge pump 11. The operation of the sludge discharge pump 11 is controlled by a level gauge 12 to ensure efficient operation. Above the temporary sludge hoppers 9, inclined tube supports 8 support inclined tube packing 6, through which wastewater flows from bottom to top for sludge-water separation. To prevent clogging of the inclined tube packing 6, the equipment is also equipped with an air washing pipe 16. Air is supplied to the air washing pipe via an air compressor to remove blockages from the inclined tube packing 6. Meanwhile, the equipment is also equipped with a water distribution channel 2 to evenly distribute sewage, as well as a water collection tank 3 and an outlet weir 4 to collect and discharge clarified water.

[0033] Furthermore, each sludge discharge pipe 10 has a sleeve valve 17 installed at the end of the inclined sludge storage hopper 15, which can adjust the amount of sludge discharged. The upper end of the sleeve valve 17 passes through the upper end of the inclined sludge storage hopper 15 and is installed on the upper surface. A manual butterfly valve 13 is installed at the upper end of the air inlet 14 at the lower end of the sludge discharge pipe 10.

[0034] The sleeve valve 17 can control the amount of sludge discharged from each temporary sludge hopper 9, and adjust the sludge discharge rate according to actual needs, improving the flexibility and efficiency of the equipment. The manual butterfly valve 13 provides a means to close the gas passage when necessary, improving the accuracy and efficiency of sludge treatment when maintaining the sludge discharge pipe 10 or the inclined sludge storage hopper 15, or when it is necessary to deal with the blockage of a particular temporary sludge hopper 9 individually.

[0035] Furthermore, the inclined surface of the sludge hopper 15 faces downward, and a level gauge 12 is installed on the side of the sludge hopper 15.

[0036] The sloping design facilitates smooth sludge flow and prevents accumulation within the sloping sludge hopper 15. The installation of the level gauge 12 provides a means of real-time monitoring of the sludge volume within the sloping sludge hopper 15, which is crucial for controlling the operation of the sludge discharge pump 11 and preventing sludge overflow.

[0037] Furthermore, the width of the inclined tube support 8 and the air washing pipe is the same as the distance from the water distribution channel 2 to the other side wall of the equipment, the length of the inclined tube support 8 and the air washing pipe is the same as the length of the equipment shell 1, the upper end of the inclined tube packing 6 on the inclined tube support 8 is the clear water zone 7, and the area between the inclined tube support 8 and the temporary mud storage hopper 9 is the water distribution zone 5.

[0038] The water distribution zone 5 ensures that the sewage can flow evenly through the inclined tube packing 6, while the clear water zone 7 provides space for collecting the clarified water.

[0039] Furthermore, a water distribution channel 2 is provided at the upper part of the inner shell 1 of the equipment in a direction perpendicular to the inclined sludge storage hopper 15. A water collection trough 3 of the same length as the water distribution channel 2 is provided on the upper part of one side of the water distribution channel 2. Holes leading to the water distribution area 5 are evenly opened at the bottom of the water distribution channel 2. The upper half of the side of the water collection trough 3 that is not adjacent to the water distribution channel 2 is connected to multiple water outlet weirs 4.

[0040] The water distribution channel 2 ensures that the wastewater is evenly distributed within the sedimentation tank, improving the efficiency of mud-water separation. The design of the water collection trough 3 and the outlet weir 4 helps to collect the clarified water and smoothly discharge it from the sedimentation tank, avoiding the impact of water flow disturbance on the sedimentation effect. The outlet of the water distribution channel 2 is located in the water distribution area 5, which can prevent the incoming wastewater from interfering with the upper clear water area 7.

[0041] Furthermore, the outlet weir 4 is parallel to the bottom of the equipment shell 1 and is evenly arranged on one side of the water collection tank 3, and the opening of the outlet weir 4 is provided with continuous serrations.

[0042] The outlet weir 4 helps to smoothly discharge the clarified water, avoiding the impact of sudden changes in water flow on the sedimentation effect. The serrated shape increases the surface area of ​​the outlet weir 4, which helps to disperse the water flow, reduce the impact force of the water flow, and thus improve the quality of the discharged water.

[0043] Furthermore, the outer casing 1 and the temporary mud hopper 9 are both made of steel.

[0044] The method of using this utility model is as follows:

[0045] A multi-hopper, non-clogging inclined tube sedimentation device achieves sludge-water separation by introducing wastewater from the aeration tank into the multi-temporary sludge hopper 9. Wastewater flows by gravity or is guided into the distribution channel 2, where it is evenly distributed and then enters the water distribution zone 5 through bottom holes. From bottom to top, the wastewater passes through the inclined tube packing 6 supported by the inclined tube support 8 for sludge-water separation. Clarified water flows to the upper clear water zone 7, is collected by the effluent weir 4, and then flows into the collection trough 3, leading to the outlet. Concentrated sludge is temporarily stored in the temporary sludge hopper 9. The concentrated sludge is discharged from the sludge discharge pipe 10 to the inclined sludge storage hopper 15 by water pressure; the amount of sludge discharged can be adjusted by regulating the height of the sleeve valve 17. During operation, the sludge in the inclined sludge storage hopper 15 is transported to the anaerobic tank by the sludge discharge pump 11, the operation of which is controlled by the level gauge 12.

[0046] Because of the adhesiveness of activated sludge, it inevitably sticks to the inclined tube packing 6, causing the honeycomb-like hexagonal pores of the inclined tube packing 6 to become blocked. At this time, air is supplied to the air washing pipe 16 under the inclined tube support 8 by an air compressor, so as to achieve the function of air washing the inclined tube packing 6, thereby solving the problem of blockage of the inclined tube packing 6 and the subsequent failure of the effluent to become clear.

[0047] If the temporary mud hopper 9 is blocked, the manual butterfly valve 13 corresponding to the end of the mud discharge pipe 10 can be closed, and the air compressor can be turned on to supply air to the air inlet 14. The mud discharge pipe 10 and the temporary mud hopper 9 will be cleared by the air, thus solving the problem of blockage in the mud discharge pipe 10 and the temporary mud hopper 9.

[0048] Compared to the traditional single-tank ...

[0049] Furthermore, both the outer casing 1 and the temporary sludge hopper 9 are made of steel, allowing for more precise welding dimensions compared to reinforced concrete structures. The temporary sludge hopper 9 can be made smaller and more numerous. This change in structure, with multiple temporary sludge hoppers 9, reduces the height of the hoppers, solving transportation problems. Even small-scale wastewater treatment plants can utilize inclined tube sedimentation equipment.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
