Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment technical field, specifically a sewage treatment sedimentation tank with partition wall structure. BACKGROUND

[0002] The sedimentation tank is an important facility widely used in the water treatment process, which is usually used to separate suspended particles and sediments and other impurities in water to achieve the purpose of purifying water quality. It generally utilizes gravity to make the suspended solids in water gradually sink to the bottom of the tank under the influence of gravity, and separate from the clear water in the upper layer to achieve solid-liquid separation. There are various types of sedimentation tanks, such as horizontal flow sedimentation tank, vertical flow sedimentation tank, radial flow sedimentation tank and inclined pipe (plate) sedimentation tank, etc. Different types differ in structure, water flow characteristics and application scenarios, and can be applied to sewage treatment plants, water treatment plants and industrial wastewater treatment, etc. It is one of the key links to protect water quality, realize water resource recycling and environmental protection.

[0003] The water in the sedimentation zone will flow into the effluent zone after completing solid-liquid separation, and then flow into the next stage of sedimentation tank or other equipment for further purification. In order to improve work efficiency, the sedimentation zone and the effluent zone are usually set together and separated by installing partition walls. However, under the influence of factors such as water pressure, water flow impact and temperature change of sewage for a long time, the connection of the partition wall is prone to loosen, which reduces the overall structural stability and increases the risk of partition wall fracture.

[0004] At present, in the prior art, support plates are usually installed uniformly between the partition walls on both sides of the effluent zone to increase the strength and stability of the partition wall. However, in actual application, only the installation of support plates can strengthen the connection effect of the partition wall, which can only reinforce the small area of the partition wall, and it is difficult to comprehensively support and protect the partition wall, which is prone to fracture in other areas of the partition wall. Once the partition wall is fractured, the flow pattern of the sewage in the sedimentation zone will be severely damaged, the sedimentation effect will be greatly reduced, and the quality and efficiency of sewage treatment will be directly affected. The subsequent repair work will also consume a lot of resources and cause production stagnation. UTILITY MODEL CONTENTS

[0026] The utility model provides a sewage treatment sedimentation tank with partition wall structure, the one side of the partition wall of sedimentation area is provided with support frame 4, thereby provides support force to one side of partition wall 2, thereby offsetting the pressure of water pressure in the other side of partition wall 2 sedimentation area, the connection strength and stability of partition wall 2 are enhanced, thereby provide the processing efficiency of sewage.

[0027] In the embodiment, a sewage treatment sedimentation tank with partition wall structure is as shown in Figure 1 and Figure 2 , wherein Figure 2 Only the local part of the partition wall of sedimentation area is shown, mainly showing the part related to the utility model.

[0028] The utility model discloses a sewage treatment sedimentation tank with partition wall structure includes sedimentation tank body 1, the inside of sedimentation tank body 1 is divided into sedimentation zone and effluent zone, and the partition wall 2 is fixedly installed between sedimentation zone and effluent zone, the support plate 3 is evenly installed on the side of the partition wall 2 far away from the sedimentation zone, and the support frame 4 is also evenly installed on the side of the partition wall 2 far away from the sedimentation zone. The cross section of support frame 4 is set to be a right triangle shape, the right angle side of support frame 4 is fixedly installed on one side of partition wall 2 and the bottom end of sedimentation tank body 1 by pouring installation method, and the two sides of the oblique angle side of support frame 4 are provided with reinforcing components. The partition wall between the sedimentation zone in the prior art is only connected and reinforced by support plate 3, can only protect the area near the two ends of support plate 3, is difficult to comprehensively protect partition wall 2, and the bottom water pressure of one side of partition wall 2 is larger, is more likely to cause the influence on the connecting place of partition wall 2 and the bottom of sedimentation tank body 1, increases the risk of the bottom end of partition wall 2 breaking, and after the support frame 4 of the embodiment is used to the partition wall of the sedimentation zone, the one side of partition wall 2 can be comprehensively reinforced and protected, and the connecting place of the bottom end of partition wall 2 is provided with more connecting and reinforcing effects by the right angle of support frame 4, further avoids the problem of partition wall 2 breaking, guarantees the normal work of sedimentation tank body 1, and improves its processing quality and efficiency.

[0029] Further, in the present embodiment, as shown in Figure 2 and Figure 3 , the reinforcing component includes a first reinforcing piece 5 and a fixed bolt 6, two first reinforcing pieces 5 are arranged, the first reinforcing piece 5 is arranged on the two sides of the support frame 4, and the fixed bolt 6 is connected together through the through slot 7, and the through slot 7 is arranged on the side wall of the support frame 4. In this way, by installing the first reinforcing piece 5, the stress acting on the oblique angle side of the support frame 4 can be relieved, and the stress situation of the partition wall 2 is different, the oblique angle side of the support frame 4 additionally receives stress transmission of the two right angle sides, and is the key part of the stress of the support frame 4, so in the process of supporting the partition wall 2 by the support frame 4, the oblique angle side of the support frame 4 is more likely to be stressed and damaged, and the first reinforcing piece 5 is installed on the two sides of the oblique angle side of the support frame 4, so that the stress area of the oblique angle side of the support frame 4 can be increased, thereby effectively relieving and dispersing the stress distribution of the oblique angle side of the support frame 4, and further improving the stability of the support frame 4.

[0030] In addition, the first reinforcing member 5 can be installed on both sides of the support frame 4 by means of bolting, welding, etc. In the present embodiment, it is preferred to use fixing bolts 6 and through grooves 7 to fix the first reinforcing member 5 on both sides of the support frame 4 by means of bolting. Compared with other installation methods, this can increase the connection strength of the connection, further improve the stability of the support frame 4, and the use of bolting makes the installation process simple and convenient, and the adjustment of the tightness is very flexible. At the same time, in order to avoid the threaded part of the fixing bolt 6 being in the underwater environment for a long time, rusting easily occurs, thereby changing the strength and hardness of the fixing bolt 6, causing the fixing bolt 6 to be more prone to breaking, and causing the stability of the support frame 4 to decrease. A waterproof coating can be provided on one side of the fixing bolt 6, or an O-ring can be provided on one side of the through groove 7.

[0031] Embodiment Two

[0032] In order to ensure the support strength of the support frame 4, in the present embodiment, as shown in Figure 3 and Figure 4 , the two ends of the through groove 7 provided in the inner wall of the support frame 4 are also provided with installation grooves 8, and the inner walls of the through groove 7 and the installation groove 8 are fixedly installed with reinforcing rings 9. This design can install reinforcing rings 9 for reinforcing the support effect in the installation groove 8 when the internal strength of the support frame 4 is reduced due to the through groove 7, thereby ensuring the internal strength of the support frame 4 and enhancing the stability of the support frame 4. The reinforcing ring 9 is divided into two parts of a barrel body and an end head and is spliced together, the barrel body is installed on the inner wall of 7, and the end head is installed on the inner wall of 8. The barrel body can be made of high-strength materials such as titanium alloy, thereby improving the internal strength of 4. The end head can be made of carbon fiber composite material or glass fiber composite material, thereby ensuring high strength and corrosion resistance while further improving the sealing performance to prevent water from entering the through groove 7 and corroding the threaded part of the fixing bolt 6.

[0033] Embodiment Three

[0034] In the present embodiment, as shown in Figure 2 and Figure 3As shown, one side of the first reinforcing member 5 is fixedly installed with the second reinforcing member 10, one end of the second reinforcing member 10 close to the first reinforcing member 5 abuts the midpoint of the first reinforcing member 5, and the other end of the second reinforcing member 10 away from the first reinforcing member 5 abuts the right angle of the support frame 4. In this way, the first reinforcing member 5 and the right angle of the support frame 4 can be connected through the second reinforcing member 10, so as to disperse the stress of the midpoint of the first reinforcing member 5 to the right angle of the support frame 4, avoid stress concentration in the area where the first reinforcing member 5 bears the most stress, and through the setting of the second reinforcing member 10, multiple triangular structures can be formed to more effectively disperse stress and improve the stability of the overall structure of the support frame 4, avoiding the risk of structural deformation. In the embodiment, one end of the second reinforcing member 10 abuts one side of the midpoint of the first reinforcing member 5, and in other embodiments, the area where the first reinforcing member 5 bears the most stress can be calculated according to the actual situation, and one end of the second reinforcing member 10 abuts this area, so as to maximize the dispersion of the stress distribution of the first reinforcing member 5.

[0035] Embodiment Four

[0036] In this embodiment, as shown in the figure, Figure 3 one side of the first reinforcing member 5 is fixedly installed with the first reinforcing nail 11, which is arranged at the midpoint of the support frame 4 and the first reinforcing member 5. The first reinforcing nail 11 can be a peg or a spiral spike. In this embodiment, the first reinforcing nail 11 is a spiral spike. In this way, on the one hand, the connection strength of the support frame 4 and the first reinforcing member 5 can be further improved, thereby enhancing the strength of the overall structure, and on the other hand, the load borne by the rod part can be dispersed to a larger area, thereby avoiding stress concentration at a certain point of the support frame 4 and the first reinforcing member 5, allowing the support frame 4 and the first reinforcing member 5 to bear the load more evenly, reducing local stress, and improving the carrying capacity. In this embodiment, the first reinforcing nail 11 is fixedly installed at the midpoint of the support frame 4 and the first reinforcing member 5. In other embodiments, the area where the support frame 4 bears the most stress can be calculated according to the actual situation, and the midpoint of the first reinforcing member 5 is installed at this area and fixed through the first reinforcing nail 11, so as to maximize the dispersion of the stress distribution of the first reinforcing member 5, and the installation position of the first reinforcing member 5 can be positioned.

[0037] Further, in the embodiment, one side of the first reinforcing nails 11 is provided with the second reinforcing nails 12, the second reinforcing nails 12 connect the two first reinforcing pieces 5 together through the support frame 4, the horizontal position of the second reinforcing nails 12 is higher than that of the first reinforcing nails 11, specifically, the installation position of the second reinforcing nails 12 needs to be determined according to the actual situation, for example, after the water in the sedimentation tank body 1 is separated for a period of time, more impurities are accumulated at the bottom end of the sedimentation area, the impurities are compressed under the action of gravity, which causes the horizontal height of the bottom end of the water body to be lifted, thereby affecting the force position of the water pressure on the partition wall 2 and the force position of the partition wall 2 on the support frame 4, so that the maximum stress position of the support frame 4 changes, the point at this time is set as the installation point of the second reinforcing nail 12, in this way, after a certain amount of sediment is accumulated at the bottom end of the sedimentation area, the sediment generates additional pressure on the support frame 4, which causes the stress maximum point to deviate, after the second reinforcing nail 12 is installed, the stress maximum point can still be relieved and dispersed at this time, and in the process of the stress maximum point deviating, the stress maximum point is always in the relief protection range of the first reinforcing nail 11 and the second reinforcing nail 12, thereby the structure is improved.

[0038] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
