Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a high-efficiency sedimentation tank with adjustable anti-buoyancy water collection trough. Background Technology

[0002] Sedimentation tanks, an important wastewater treatment structure, primarily rely on gravity settling to remove suspended particles denser than water. The collection trough is a crucial component of the sedimentation tank, located above it. During startup, the steel collection trough experiences significant buoyancy, which can cause deformation of the trough or its supports. To balance this buoyancy, circular through-holes are typically created at the bottom. However, this can lead to a gushing phenomenon. When pressure relief holes are created at the bottom of the trough, if the water pressure inside the trough is higher than the external ambient pressure (especially if the water inside the trough is deeper or the external area is still water), water will jet upwards at high speed through these holes, disrupting the stability of the sedimentation tank and reducing sedimentation efficiency. Furthermore, the flatness of the collection trough significantly impacts sedimentation effectiveness. Currently, most sedimentation tanks have non-adjustable collection trough heights; if the installation is not level, it is difficult to adjust later, affecting the quality of the effluent. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable anti-buoyancy collection trough for a high-efficiency sedimentation tank, which effectively solves the problem of the impact of the bottom through-hole and flatness of the collection trough on the sedimentation efficiency of the sedimentation tank.

[0004] According to the present invention, a high-efficiency sedimentation tank with adjustable anti-buoyancy water collection trough includes: a sedimentation tank and multiple height-adjustable water collection troughs disposed within the sedimentation tank. A connecting mechanism is provided between the tank wall of the sedimentation tank and the multiple water collection troughs. A weir is provided at the top of the water collection troughs, and an anti-buoyancy adjustment component is provided at the bottom of the water collection troughs.

[0005] Preferably, the connecting mechanism includes two connectors symmetrically arranged on the two side walls of the sedimentation tank, and a distance adjusting member corresponding to each of the two connectors. The distance adjusting member has a first end and a second end. The first end of the distance adjusting member is connected to the connector, and the second end of the distance adjusting member is connected to the water collection tank.

[0006] Preferably, the connector is a fixed angle steel, which has a connecting hole that is connected to the first end of the distance adjusting member.

[0007] Preferably, the distance adjustment component is an adjustable bolt, with the first end of the adjustable bolt connected to the connecting hole and the second end of the adjustable bolt connected to the water collection tank.

[0008] Preferably, the anti-buoyancy adjustment component includes a plurality of through holes arranged at intervals at the bottom of the water collection tank, and anti-buoyancy components installed corresponding to each of the through holes.

[0009] Preferably, the anti-buoyancy component includes a support rod passing through the through hole and two baffles sleeved on the support rod. Limiting components are provided at both ends of the support rod. The two baffles are respectively located between the limiting component at the first end of the support rod and the inside of the bottom of the water collection tank, and between the limiting component at the second end of the support rod and the outside of the bottom of the water collection tank.

[0010] Preferably, the baffle material is rubber.

[0011] Preferably, the diameter of the anti-buoyancy component is 2-3 times that of the through hole.

[0012] Beneficial effects:

[0013] This invention allows the position of the water collection trough in the sedimentation tank to be adjusted according to actual needs, ensuring the flatness of the trough to ±2mm and avoiding low sedimentation efficiency caused by unevenness. Simultaneously, the anti-buoyancy adjustment component effectively prevents the trough from floating due to rising water levels, further guaranteeing the sedimentation efficiency of the sedimentation tank. Furthermore, the rubber baffle not only enhances the anti-buoyancy of the trough but also improves its durability and extends its service life. Attached Figure Description

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] Combination Figures 1 to 2This embodiment shows a high-efficiency sedimentation tank 1 with an adjustable anti-buoyancy water collection tank 2, including: sedimentation tank 1 and multiple water collection tanks 2 with adjustable height installed in sedimentation tank 1. A connecting mechanism 3 is provided between the tank wall of sedimentation tank 1 and the multiple water collection tanks 2. A weir 4 is provided at the top of the water collection tank 2 and an anti-buoyancy adjustment component 5 is provided at the bottom of the water collection tank 2.

[0019] It should be noted that multiple U-shaped water collection troughs 2 are evenly spaced inside the sedimentation tank 1. The two opposite ends of the sedimentation tank 1 are equipped with height-adjustable connecting mechanisms 3, which are connected to the water collection troughs 2 to adjust the level of the water collection troughs 2 relative to the sedimentation tank 1. The top of the water collection troughs 2 is equipped with U-shaped or V-shaped weirs 4 for evenly distributing and draining water. The bottom of the water collection troughs 2 is equipped with anti-buoyancy adjustment components 5 to solve the problem of water flow buoyancy squeezing and deforming the water collection troughs 2 and affecting the sedimentation effect of the sedimentation tank 1 when the sedimentation tank 1 starts to receive water.

[0020] The connecting mechanism 3 includes two connectors 31 symmetrically arranged on the two side walls of the sedimentation tank 1, and a distance adjusting member 32 corresponding to the two connectors 31. The distance adjusting member 32 is provided with a first end and a second end. The first end of the distance adjusting member 32 is connected to the connector 31, and the second end of the distance adjusting member 32 is connected to the water collection tank 2.

[0021] It should be noted that by adjusting the length of the distance adjustment components 32 located at both ends of the water collection tank 2, the levelness and height of the water collection tank 2 relative to the sedimentation tank 1 can be precisely adjusted to ensure the stability of the water collection tank 2 in the sedimentation tank 1 and the uniform diversion and drainage effect.

[0022] The connector 31 is a fixed angle steel with a connecting hole, which is connected to the first end of the distance adjustment component 32.

[0023] It should be noted that the fixed angle steel has multiple connection holes. In order to ensure the connection stability of the water collection tank 2 in the sedimentation tank 1, the fixed angle steel is firmly connected to the first end of the distance adjustment component 32 by fasteners such as bolts passing through the connection holes. This connection method not only facilitates installation and disassembly, but also facilitates subsequent fine-tuning of the position and level of the water collection tank 2. The design of the fixed angle steel enhances the strength and stability of the connection parts, ensuring the reliability and safety of the sedimentation tank 1 during long-term operation. At the same time, the way the fixed angle steel is provided with connection holes also provides flexible installation options to adapt to different installation environments and needs.

[0024] The distance adjustment component 32 is an adjustable bolt. The first end of the adjustable bolt is connected to the connecting hole, and the second end of the adjustable bolt is connected to the water collection tank 2.

[0025] It should be noted that the adjustable bolt is equipped with a locking nut, which can be tightened to fix the length of the adjustable bolt, thereby achieving precise adjustment of the level and height of the water collection tank 2. Furthermore, the adjustable bolt is preferably made of stainless steel, which has good corrosion resistance and strength, ensuring stability and reliability under long-term use.

[0026] The anti-buoyancy adjustment component 5 includes a plurality of through holes 52 arranged at intervals at the bottom of the water collection tank 2, and anti-buoyancy components 51 installed in one-to-one correspondence with the through holes 52.

[0027] It should be noted that the size of the through hole 52 at the bottom of the water collection tank 2 is 15-20mm.

[0028] The anti-buoyancy component 51 includes a support rod 511 passing through the through hole 52 and two baffles 512 sleeved on the support rod 511. Limiting components 513 are provided at both ends of the support rod 511. The two baffles 512 are respectively located between the limiting component 513 at the first end of the support rod 511 and the inside of the bottom of the water collection tank 2, and between the limiting component 513 at the second end of the support rod 511 and the outside of the bottom of the water collection tank 2.

[0029] It should be noted that the diameter of the support rod 511 is smaller than the size of the through hole 52, which helps water flow from the bottom of the water collection tank 2. The support rod 511 has threads at both ends, and the two limiting components 513 are nuts, detachably connected to both ends of the support rod 511. A washer can be placed between the nut and the baffle 512 to increase the friction and tightening force between them, preventing the nut from loosening during use and ensuring the stability and reliability of the anti-buoyancy component 51. The material of the washer can be selected according to actual needs, such as rubber, plastic, or metal, to meet different working environments and usage requirements. The two baffles 512 are located between the limiting component 513 at the first end of the support rod 511 and the bottom of the water collection tank 2, and the limiting component 513 at the second end of the support rod 511 and the water collection tank 2. Between the bottom of the water tank 2 and the outside, the two baffles 512 move up and down between two positions respectively; when the sedimentation tank 1 is not filled with water, the anti-buoyancy component 51 is subjected to gravity, and the upper baffle 512 will completely cover the bottom through hole 52 of the bottom of the water collection tank 2. When the sedimentation tank 1 starts to be filled with water, the external water pressure is greater than the internal pressure of the tank, and the water will push open the upper baffle 512 to balance the anti-buoyancy pressure and solve the problem of water gushing out of the bottom through hole 52; as the liquid level in the water collection tank 2 rises, when the liquid level difference between the inside and outside of the water collection tank 2 is small, the baffle 512 automatically falls and closes, and all the water enters from the top weir 4 of the water collection tank 2; the length of the support rod 511 and the size and weight of the baffle 512 can be adjusted according to actual needs to adapt to sedimentation tanks 1 of different depths, further improving the adaptability and practicality of the anti-buoyancy component 51.

[0030] The baffle 512 is made of rubber.

[0031] It should be noted that the rubber baffle 512 not only has good sealing performance to prevent water from leaking through the through hole 52, but also deforms to a certain extent when subjected to buoyancy, absorbing part of the buoyancy and further improving the stability of the water collection tank 2.

[0032] The diameter of the anti-buoyancy component 51 is 2-3 times that of the through hole 52.

[0033] It should be noted that the diameter of the anti-buoyancy component 51 is designed to be 2-3 times that of its through hole 52. This ensures that the anti-buoyancy component 51 can provide sufficient area to produce the necessary sealing effect when covering the through hole 52, preventing water from leaking from the through hole 52 when the sedimentation tank 1 is not filled with water or the water level is low. At the same time, when the sedimentation tank 1 begins to be filled with water, the larger size of the anti-buoyancy component 51 helps to slow down the speed at which water enters the through hole 52, further reducing the effect of water flow on the sedimentation and purification effect of the sedimentation tank 1.

[0034] Working principle:

[0035] When the water level in sedimentation tank 1 rises, the water collection tank 2 tends to float due to the buoyancy of the water. However, due to the design of the anti-buoyancy component 51, the support rod 511 passes through the through hole 52, and the support rod 511 can move up and down in the through hole 52. The two ends of the support rod 511 are fixed by the limiting component 513, so that the two baffles 512 move up and down between the limiting component 513 at the first end of the support rod 511 and the inside of the bottom of the water collection tank 2, and between the limiting component 513 at the second end of the support rod 511 and the outside of the bottom of the water collection tank 2. When the sedimentation tank 1 is not filled with water, the anti-buoyancy component 51 is tightly fitted to the corresponding through hole 52 under the action of gravity. When the water level rises rapidly and the liquid level difference inside and outside the water collection tank 2 reaches a certain value, the anti-buoyancy valve is automatically opened by water pressure. As the liquid level in the water collection tank 2 rises, when the liquid level difference inside and outside the water collection tank 2 is small, the anti-buoyancy valve automatically falls and closes, and all the water enters from the top weir 4 of the water collection tank 2.

[0036] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
