Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an adjustable water outlet weir. Background Art

[0002] In the existing sewage treatment, the water flow between the tank bodies is generally carried out in three modes: pipes, wall holes and water outlet weirs. Pipes and wall holes generally have water outlets in the middle or bottom. In some cases, the most suitable water outlet mode is top water outlet, and the water outlet weir mode is top water outlet. The elevation of the water outlet weir determines the effective water depth and effective pool capacity of the entire tank body. The construction of the water outlet weir generally adopts steel concrete casting or stainless steel triangular weir installation. The former elevation determines that the effective water depth and pool capacity cannot be adjusted. Even if the latter can be adjusted, it requires huge manpower and material resources. First, the welding is removed, and then the water outlet weir benchmark is changed by crane hoisting, and then welding is performed for secondary fixation. It cannot be used as a means to adjust the effective water depth and pool capacity in daily production and operation of sewage treatment.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and an adjustable water outlet weir is proposed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an adjustable water outlet weir, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustable water outlet weir, including a wall-mounted frame and a gate assembly, the surface of the wall-mounted frame is provided with bolt holes, and stainless steel panels are fixed on both sides of the wall-mounted frame, the wall-mounted frame wraps the water outlet on the surface of the pool body, and the wall-mounted frame is fixed to the inner wall of the pool body by expansion bolts passing through the bolt holes, a first stainless steel angle iron is distributed on the lower part of the inner wall of the wall-mounted frame, and a fixing plate is fixed on the outer surface of the first stainless steel angle iron, the fixing plate is in an L-shaped structure and its bottom covers the gap between the bottoms of the stainless steel panels, a second stainless steel angle iron is fixed on the inner side of the stainless steel panel, and a stainless steel rail is fixed on the surface of the second stainless steel angle iron, and the gate assembly is arranged inside the stainless steel rail.

[0006] Furthermore, an operating floating platform is distributed in parallel on the front side of the fixed plate, and the operating floating platform floats on the water level surface in the pool body.

[0007] Furthermore, the gate assembly includes a cavity gate and an inner cavity movable pressure plate, the outer opening structures at both ends of the cavity gate are adapted to the inner opening structure of the stainless steel rail, and the height of the cavity gate is 350m or 200m.

[0008] Furthermore, the gate assembly also includes a movable pressure plate, and the movable pressure plate is penetrated through the inner side surface of the cavity gate.

[0009] Furthermore, the gate assembly also includes an adapting airbag, the interior of the inner cavity is provided with the adapting airbag, and the overall structure of the adapting airbag after being filled with air is adapted to the internal structure of the inner cavity.

[0010] Furthermore, the side surface of the adapting airbag is fixedly connected to the side surface of the movable pressure plate, and the side of the movable pressure plate away from the adapting airbag faces the inner wall of the pool body.

[0011] Furthermore, the gate assembly also includes a transmission channel, and the top and bottom of the adapter airbag are both provided with transmission channels.

[0012] Furthermore, the gate assembly also includes a first sealing strip, and the top of the cavity gate is provided with the first sealing strip, and the first sealing strip is connected to the adapter airbag through a transmission channel.

[0015] The present invention provides an adjustable water outlet weir, which has the following beneficial effects:

[0016] 1. When the adjustable water outlet weir is draining water at the outlet, the water body is limited and guided by the stainless steel panel, the fixed plate and the cavity gate plate so that the water body is discharged from the top surface of the uppermost cavity gate plate to the outside of the pool body. By adjusting the height specifications of the cavity gate plate, several cavity gate plates are inserted into the stainless steel track, thereby the water depth and pool capacity can be flexibly and effectively adjusted according to needs.

[0017] 2. When water is continuously injected into the pool body, the adjustable water outlet weir is discharged from the water outlet and continuously pushes against the movable pressure plate. The movable pressure plate shrinks inward along the inner side of the cavity gate plate and pushes the adaptor airbag. When the adaptor airbag is compressed, the internal gas enters the first sealing strip and the second sealing strip along the transmission channel to increase the pressure between the first sealing strip and the second sealing strip, so that the two are more tightly engaged. At the same time, a lock is arranged on the outer wall of the stainless steel track and locked to prevent the first sealing strip and the second sealing strip from lifting the cavity gate plate. The fluidity of the water when injected can be used to enhance the stability of the cavity gate plate inside the stainless steel track and the sealing after splicing.

[0027] The specific operation is as follows: first, the wall frame 1 is attached to the inner wall of the pool body so that the wall frame 1 wraps the column outlet part, and the wall frame 1 is fixed by passing the expansion bolt through the bolt hole 2 and driving it into the wall body, and the cavity gate plate 801 of the corresponding height is selected according to the required water depth and pool capacity. The height specification of the cavity gate plate 801 includes but is not limited to 350mm or 20mm. The cavity gate plates 801 of the corresponding height specifications are inserted into the stainless steel track 7 in sequence, and after the insertion is completed, a lock buckle is set on the outer wall of the stainless steel track 7 and locked, and the lock buckle position is located on the top surface of the uppermost cavity gate plate 801. At this time, the lowermost cavity gate plate 801 is in contact with the top surface of the fixing plate 5;

[0028] Then, when discharging water at the outlet, the water body is limited and guided by the stainless steel panel 3, the fixed plate 5 and the cavity gate plate 801 so that the water body is discharged from the top surface of the uppermost cavity gate plate 801 to the outside of the pool body, and by adjusting the height specifications of the cavity gate plate 801, a number of cavity gate plates 801 are inserted into the stainless steel track 7, so that the water depth and pool capacity can be flexibly and effectively adjusted according to needs. Therefore, the adjustable water outlet weir has an integrated structure for the basic part, namely the wall frame 1, the stainless steel panel 3, the first stainless steel angle iron 4, the fixed plate 5, the second stainless steel angle iron 6, and the stainless steel track 7. The adjustable weir part adopts a hollow stainless steel movable plate, namely the cavity gate plate 801. The height size of the cavity gate plate 801 can be customized according to user needs. The weight of a single cavity gate plate 801 does not exceed 10 kg, and it is equipped with an above-water operating platform, namely an operating floating platform. A single employee can adjust the effective water depth, which can make the adjustment of the water depth a routine operation method in the sewage treatment process.

[0029] like Figure 1-Figure 6 As shown, the gate assembly 8 also includes a movable pressure plate 803, the inner side of the cavity gate 801 is penetrated with the movable pressure plate 803, the gate assembly 8 also includes an adapting airbag 804, the interior of the inner cavity 802 is provided with the adapting airbag 804, and the overall structure of the adapting airbag 804 after being filled with air is adapted to the internal structure of the inner cavity 802, the side of the adapting airbag 804 is fixedly connected to the side of the movable pressure plate 803, and the side of the movable pressure plate 803 away from the adapting airbag 804 faces the inner wall of the pool body, the gate assembly 8 also includes a transmission channel 805, the adapting airbag 804 The top and the bottom are both provided with transmission channels 805, the gate assembly 8 further includes a first sealing strip 806, the top of the cavity gate 801 is provided with the first sealing strip 806, and the first sealing strip 806 is communicated with the adapting airbag 804 through the transmission channel 805, the gate assembly 8 further includes a second sealing strip 807, the bottom of the cavity gate 801 is provided with the second sealing strip 807, and the second sealing strip 807 is communicated with the adapting airbag 804 through the transmission channel 805, and the first sealing strip 806 and the second sealing strip 807 are in a mutually engaging structure;

[0030] The specific operation is as follows. After the cavity gate plate 801 is inserted into the stainless steel track 7, the two adjacent cavity gate plates 801 are engaged with each other through the first sealing strip 806 and the second sealing strip 807 to enhance the sealing performance. When water is continuously injected into the pool body, the water is discharged from the water outlet and continuously pushes against the movable pressure plate 803. The movable pressure plate 803 shrinks inward along the inner side of the cavity gate plate 801 and pushes the adaptor airbag 804. When the adaptor airbag 804 is compressed, the internal gas enters the first sealing strip 806 and the second sealing strip 807 along the transmission channel 805 to enhance the pressure between the first sealing strip 806 and the second sealing strip 807, so that the two are more tightly engaged. At the same time, a lock is set on the outer wall of the stainless steel track 7 and locked to prevent the first sealing strip 806 and the second sealing strip 807 from lifting the cavity gate plate 801. The fluidity of the water when injected is used to enhance the stability of the cavity gate plate 801 inside the stainless steel track 7 and the sealing performance after splicing.

[0031] like Figure 1-Figure 6 As shown, the gate assembly 8 also includes a disassembly handle 808, and the inner and outer sides of the cavity gate 801 are fixed with a disassembly handle 808, and the front of the fixed plate 5 is parallelly distributed with an operating floating platform, and the operating floating platform floats on the water level surface of the pool body;

[0032] The specific operation is as follows: when the water depth needs to be adjusted, a single person stands on the operating platform, removes the lock, and takes out the cavity gate 801 from the inside of the stainless steel rail 7 by holding the disassembly handle 808, and replaces the cavity gate 801 with the height size corresponding to the required water depth. In this way, a single person can adjust the water depth.

[0033] In summary, when the adjustable water outlet weir is used, first, the wall frame 1 is attached to the inner wall of the pool body so that the wall frame 1 wraps the column water outlet part, and the wall frame 1 is fixed by passing the expansion bolt through the bolt hole 2 and driving it into the wall body, and the cavity gate plate 801 of the corresponding height is selected according to the required water depth and pool capacity. The height specification of the cavity gate plate 801 includes but is not limited to 350mm or 20mm. The cavity gate plates 801 of the corresponding height specifications are inserted into the stainless steel track 7 in sequence, and after the insertion is completed, a lock buckle is set on the outer wall of the stainless steel track 7 and locked, and the lock buckle position is located on the top surface of the uppermost cavity gate plate 801, and at this time, the lowermost cavity gate plate 801 is in contact with the top surface of the fixing plate 5;

[0034] When the water is discharged from the water outlet, the water is limited and guided by the stainless steel panel 3, the fixed plate 5 and the cavity gate 801 so that the water is discharged from the top surface of the uppermost cavity gate 801 to the outside of the pool. By adjusting the height specifications of the cavity gate 801, several cavity gates 801 are inserted into the stainless steel track 7.

[0035] After the cavity gate plate 801 is inserted into the stainless steel track 7, the two adjacent cavity gate plates 801 are engaged with each other through the first sealing strip 806 and the second sealing strip 807 to enhance the sealing performance. When water is continuously injected into the pool body, the water is discharged from the water outlet and continuously pushes against the movable pressure plate 803. The movable pressure plate 803 shrinks inward along the inner side of the cavity gate plate 801 and pushes the adapting airbag 804. When the adapting airbag 804 is compressed, the internal gas enters the first sealing strip 806 and the second sealing strip 807 along the transmission channel 805 to enhance the pressure between the first sealing strip 806 and the second sealing strip 807, so that the two are more tightly engaged. At the same time, a lock buckle is arranged on the outer wall of the stainless steel track 7 and locked to prevent the first sealing strip 806 and the second sealing strip 807 from lifting the cavity gate plate 801, thereby enhancing the stability of the cavity gate plate 801 located inside the stainless steel track 7 and the sealing performance after splicing by virtue of the fluidity when the water is injected;

[0036] When the water depth needs to be adjusted, a single person stands on the operating platform, removes the lock, and takes out the cavity gate 801 from the inside of the stainless steel rail 7 by holding the disassembly handle 808, and replaces the cavity gate 801 with the height size corresponding to the required water depth. In this way, a single person can adjust the water depth.
