Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation devices, in particular to an inclined tube sedimentation device. Background Technique

[0002] The inclined tube sedimentation tank, as a model of efficient combined sedimentation technology, is deeply rooted in the shallow tank sedimentation theory. Its core lies in finely dividing a huge sedimentation area into multiple shallow sedimentation units by cleverly arranging inclined parallel tubes or adopting a honeycomb packing structure. This design promotes the efficient interaction and separation of sewage and sediment in their respective shallow layers, greatly improving the treatment efficiency.

[0003] Currently, the traditional inclined tube sedimentation water purification method usually realizes the rapid aggregation of suspended matter, solids, and flocculated alum after coagulation by deploying an inclined tube module with an inclination angle accurate to 60 degrees above the mud suspension layer. These impurities adhere to the bottom of the inclined tube in a thin layer and naturally slide down to the bottom of the sedimentation tank by gravity, and are finally discharged through an optimized sludge discharge system. At the same time, the clear water rises lightly and is collected in the collecting pipe for direct discharge or recycling, ensuring water purification and resource conservation. The inclined tube sedimentation device integrates the functions of sedimentation, concentration, and sludge discharge, and significantly improves the sedimentation efficiency by increasing the effective sedimentation area and shortening the sedimentation path of impurities.

[0004] However, in order to prevent the problem of incomplete sludge discharge or too slow sludge discharge speed caused by the limited sludge suction range of a single sludge discharge port, multiple sludge discharge hoppers are usually provided at the bottom of the inclined tube sedimentation tank, and the slope of the sludge discharge hopper is used to quickly discharge the sludge. However, the existing sludge discharge method mainly pumps the sludge at the bottom of the sedimentation tank through a sludge suction pump, and this method may cause sludge residue due to uneven suction, which will have an adverse impact on the overall effect of sewage treatment.

[0022] The inclined tube sedimentation device according to an embodiment of the present utility model will be described below in conjunction with the accompanying drawings.

[0023] As Figures 1 to 3 shown, the inclined tube sedimentation device according to an embodiment of the present utility model may include a sedimentation tank 1, a plurality of inclined tubes 2, two ball screw pairs 3, multiple groups of scraping assemblies 4, a plurality of branch pipes 5, and a main pipe 6.

[0025] It should be noted that an inlet is provided at a position near the bottom of the side wall of the inlet tank 7, and an outlet is provided at a position near the opening of the side wall of the discharge tank 8. The sewage is transported to the inlet tank 7 through a liquid pump, fully reacts with the flocculant in the inlet tank 7 and then enters the interior of the sedimentation tank 1. After sedimentation, the upper clear water is discharged from the discharge tank 8.

[0026] Furthermore, sludge hoppers are formed between adjacent sludge tanks 9, and the inclined surfaces of the sludge hoppers can further accelerate the sedimentation speed of the sludge.

[0027] A plurality of support rods 10 are provided inside the sedimentation tank 1, and a plurality of inclined tubes 2 are installed on the support rods 10, and the inclined tubes 2 are located above the sludge tanks 9.

[0028] It should be noted that referring to Figure 4 , a plurality of inclined tubes 2 are arranged in a honeycomb shape, and a plurality of inclined tubes are obliquely arranged inside the sedimentation tank 1. Among them, the inclination angle of the inclined tubes 2 is between 35° and 60°.

[0029] In the embodiment of the present utility model, the support rods 10 can support the inclined tubes 2, and the inclined tubes 2 are suspended above the sludge tanks 9. The sewage enters the inclined tubes 2, and under the action of the flocculant, the colloidal particles in the sewage form large aggregates and settle along the inclined tubes 2.

[0030] Grooves 11 are provided on the opposite inner walls of the sedimentation tank 1. Two ball screw pairs 3 are respectively arranged on the corresponding grooves 11, and the two ball screw pairs 3 are connected by a transmission assembly 12; a plurality of scraping assemblies 4 are arranged between the two ball screw pairs 3, and the scraping assemblies 4 are connected to the ball screw pairs 3.

[0031] It should be noted that each scraping assembly 4 includes two, and the two scraping assemblies 4 can clean the two opposite inner walls of the sludge tank 9 to accelerate the discharge speed and effect of the sludge.

[0032] A plurality of sludge discharge holes 90 are opened at the bottom of the sludge tank 9. A plurality of branch pipes 5 are respectively arranged below the corresponding sludge tanks 9, and the branch pipes 5 are communicated with the sedimentation tank 1 through the sludge discharge holes 90; a main pipe 6 is communicated with the plurality of branch pipes 5.

[0033] It should be noted that in this embodiment, the main pipe 6 is connected to a sludge suction pump, and the sludge at the bottom of the sedimentation tank 1 can be pumped out through the sludge suction pump.

[0034] In an embodiment of the present utility model, as Figure 2 and Figure 3As shown, the ball screw pair 3 may include a ball screw 30 and multiple sets of nut sliders 31. Among them, the ball screw 30 is rotatably arranged on the groove 11, and one end of the ball screw 30 extends to the outside of the sedimentation tank 1; multiple sets of nut sliders 31 are respectively sleeved on the ball screw 30, the multiple sets of nut sliders 31 are correspondingly arranged with multiple sets of scraping components 4, and the nut sliders 31 are slidably connected to the groove 11.

[0035] It should be noted that in this embodiment, multiple sets of threads are provided on the ball screw 30. Each set of threads includes two threads with opposite directions, and multiple sets of nut sliders 31 are respectively arranged on multiple sets of threads. When the ball screw 30 rotates, it can drive each set of nut sliders 31 to move towards or away from each other.

[0036] Furthermore, the groove 11 can restrict the nut slider 31 so that the nut slider 31 can move linearly.

[0037] In an embodiment of the present utility model, as Figure 1 shown, the transmission component 12 may include two sprockets 120 and a toothed chain 121. Among them, the two sprockets 120 are respectively arranged on the corresponding ball screws 30, and the two sprockets 120 are drivingly connected by the toothed chain 121.

[0038] It should be noted that one of the ball screws 30 is connected to an external driving mechanism (such as a motor). Through the external driving mechanism, the ball screw 30 can be driven to rotate, and with the cooperation of the sprocket 120 and the toothed chain 121, the other ball screw 30 can be driven to rotate synchronously.

[0039] In an embodiment of the present utility model, as Figure 3 shown, the scraping component 4 may include two support shafts 40, a plate sleeve 41, a scraper 42 and two sliding rods 43. Among them, the two support shafts 40 are respectively arranged on two oppositely arranged nut sliders 31; both ends of the plate sleeve 41 are rotatably connected to the corresponding support shafts 40; the scraper 42 is slidably connected to the plate sleeve 41; multiple sets of sliding grooves 13 are respectively arranged on the opposite surfaces of the sedimentation tank 1, the two sliding rods 43 are respectively arranged at both ends of the scraper 42, and the sliding rods 43 are slidably connected to the sliding grooves 13.

[0040] It should be noted that each set of sliding grooves 13 described in this embodiment includes two, and the two sliding grooves 13 are symmetrically arranged. When the sliding rod 43 is located at the top of the sliding groove 13, there is a gap between the scraper 42 and the sludge tank 9, and this gap facilitates the sedimentation of sludge.

[0041] Furthermore, the plate sleeve 41 is inclined, and the inclined plate sleeve 41 is also beneficial to the rapid sedimentation of sludge.

[0042] Furthermore, as Figure 2As shown, multiple sets of sliding grooves 13 are correspondingly arranged with multiple sludge tanks 9, and the sliding groove 13 includes a first inclined groove and a second inclined groove.

[0043] It should be noted that the first inclined groove of the sliding groove 13 described in this embodiment is communicatively arranged above the second inclined groove, and the inclination angle of the second inclined groove is the same as the inclination angle of the slope surface of the sludge tank 9. When the sliding rod 43 slides into the second inclined groove, one end of the scraping plate 42 is in contact with the slope surface of the sludge tank 9, so as to scrape the sludge on the slope surface of the sludge tank 9 clean.

[0044] Specifically, during the process of sedimentation of sewage, relevant personnel pump the sewage into the water inlet tank 7. After the sewage fully reacts with the flocculant in the water inlet tank 7, it flows into the interior of the sedimentation tank 1. After rapid sedimentation through multiple inclined tubes 2, the sludge and aggregates will be deposited in the interior of the sludge tank 9, and the upper clear water will flow into the discharge tank 8 and be discharged from the drainage pipe.

[0045] When there is a large amount of sludge deposited at the bottom of the sedimentation tank 1, relevant personnel control one of the ball screws 30 to rotate, and with the cooperation of the transmission assembly 12, drive the other ball screw 30 to rotate. At this time, the two nut sliders 31 in the same group move closer to each other. With the cooperation of the sliding groove 13, the scraping plate 42 is moved out of the plate sleeve 41. When the sliding rod 43 slides into the second inclined groove, the scraping plate 42 is in contact with the slope surface of the sludge tank 9, so as to scrape the silt on the slope surface of the sludge tank 9 to the bottom of the sludge tank 9, and finally the silt at the bottom of the sedimentation tank 1 is pumped out by a sludge pump.

[0046] In summary, the inclined tube sedimentation device of the embodiment of the present utility model can scrape the silt at the bottom of the sedimentation tank, accelerate the discharge speed of the silt, improve the discharge effect of the silt, and ensure the continuous and efficient operation of the sedimentation tank.
