Description

Technical Field

[0001] This utility model relates to the field of anaerobic reactor technology, specifically to a bottomless waterproof device for an anaerobic reactor. Background Technology

[0002] Anaerobic reactors are highly efficient bioreactors that utilize the metabolic activity of anaerobic bacteria to treat organic wastewater. They are widely used in the treatment of high-concentration organic wastewater. Their core principle is to decompose organic matter in wastewater into gases such as methane and carbon dioxide through the metabolism of anaerobic microorganisms, thereby achieving water purification and energy recovery.

[0003] In existing bottomless anaerobic reactor waterproofing construction, water sealing is achieved by using a bottom waterstop plate to prevent the water pressure inside the tank from exceeding the atmospheric pressure outside, thus preventing liquid from flowing out between the bottom plate and the foundation. However, in actual operation, the internal pressure is usually high, and the cleanliness of the liquid inside the tank also affects the speed and ease of liquid outflow from the bottom, leading to unstable liquid levels and affecting operation. Furthermore, some existing bottomless tanks do not consider the main sources of resistance and the flow pattern of the liquid at the bottom when sealing the bottom, resulting in leakage after sealing. Utility Model Content

Secondary grouting slurry is poured on the outside of the tank foundation. Fastening angle steel is installed between the side wall plate and the tank foundation. Fastening bolts are installed inside the fastening angle steel.

[0006] Preferably, the connection between the waterstop steel plate and the side wall plate is welded with a weld overlay protrusion to improve the welding stability of the waterstop steel plate and the side wall plate.

[0007] Preferably, the inner wall of the fastening angle steel is provided with a through hole adapted to the fastening bolt, and the fastening bolt passes through the through hole and is fixed to the bottom of the tank foundation.

[0008] Preferably, the bottom of the fastening angle steel is in contact with the bottom of the tank body foundation, and the other side of the fastening angle steel is welded and fixed to the side wall plate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 As shown, a bottomless waterproof device for an anaerobic reactor includes a tank foundation 1 and pre-embedded steel bars 2 welded to the inner wall of the tank foundation 1 to improve the structural strength of the tank. The tank foundation 1 has a side wall plate 3 inside, and a water-stop steel plate 4 is welded to the outside of the side wall plate 3. A secondary grouting slurry 5 is poured on the outside of the tank foundation 1. A fastening angle steel 6 is installed between the side wall plate 3 and the tank foundation 1, and a fastening bolt 7 is installed inside the fastening angle steel 6.

[0016] By setting up a tank foundation 1 and embedding several steel bars 2 inside the tank foundation 1, the tank body and the liquid inside the tank are supported, and the strength of the secondary grouting structure is increased. By welding a water-stop steel plate 4 to the outside of the side wall plate 3 and placing the water-stop steel plate 4 inside the tank, the resistance of the liquid flowing through the gap between the inside of the tank wall and the secondary grouting is increased, thereby improving the sealing effect and reducing the risk of leakage. The side wall plate 3 is connected and fixed to the tank foundation 1 by using fastening angle steel 6, and secondary grouting slurry 5 is poured in, which serves as a water-stop plate on the outside of the tank wall and strengthens the stability of the tank.

[0017] The connection between the waterstop steel plate 4 and the side wall plate 3 is welded with a weld overlay protrusion 41 to improve the welding stability of the waterstop steel plate 4 and the side wall plate 3; the inner wall of the fastening angle steel 6 is provided with a through hole 61 that matches the fastening bolt 7, and the fastening bolt 7 passes through the through hole 61 and is fixed to the bottom of the tank foundation 1; the bottom of the fastening angle steel 6 contacts the bottom of the tank foundation 1, and the other side of the fastening angle steel 6 is welded to the side wall plate 3; the side wall plate 3, the waterstop steel plate 4, the fastening angle steel 6 and the fastening bolt 7 are all poured into the secondary grouting slurry 5; the pre-embedded steel bars 2 are set as multiple bars and are tied together with each other. The pre-embedded steel bars 2 are made of low alloy high strength steel with high strength and toughness.

[0018] When welding the waterstop steel plate 4 to the side wall plate 3, a weld overlay protrusion 41 is welded at the weld joint to improve the welding stability of the waterstop steel plate 4 and the side wall plate 3, thus preventing water leakage at the weld joint. A through hole 61 is opened in the inner wall of the fastening angle steel 6 to facilitate the fastening bolt 7 to pass through the fastening angle steel 6 and then be inserted into the tank foundation 1 and tightened. The tank foundation 1 also has a matching hole inside, and the fastening bolt 7 is tightened to fix the fastening angle steel 6 to the tank foundation 1. The other side of the fastening angle steel 6 is welded to the side wall plate 3 to fix the side wall plate 3 to the tank foundation 1. After the pre-embedded steel bar 2, side wall plate 3, waterstop steel plate 4, fastening angle steel 6 and fastening bolt 7 are fully installed, the secondary grouting slurry 5 is poured into the tank foundation 1. The stability of the tank is enhanced through multiple structures, which strengthens the stability and sealing of the tank after the secondary pouring and extends the service life of the tank.

[0019] Working principle: The tank foundation 1 contains several pre-embedded steel bars 2, which serve to support the tank, the liquid inside, and increase the strength of the secondary grouting structure. A water-stop steel plate 4 is welded to the outside of the side wall plate 3. The water-stop steel plate 4 is placed inside the tank to increase the resistance to liquid flow through the gap between the inner side of the tank wall and the secondary grouting, thereby improving the sealing effect and reducing the risk of leakage. Fastening angle steel 6 is used to connect and fix the side wall plate 3 to the tank foundation 1, and secondary grout 5 is poured, serving as a water-stop plate on the outer side of the tank wall and strengthening the stability of the tank. When welding the water-stop steel plate 4 to the side wall plate 3, a weld overlay protrusion 41 is welded at the weld joint to further enhance the welding stability of the water-stop steel plate 4 and the side wall plate 3. This prevents water seepage at the weld points. A through hole 61 is made in the inner wall of the fastening angle steel 6 to allow the fastening bolt 7 to pass through and be inserted into the tank foundation 1 for tightening. The tank foundation 1 also has matching holes inside. Tightening the fastening bolt 7 fixes the fastening angle steel 6 to the tank foundation 1. The other side of the fastening angle steel 6 is welded to the side wall plate 3, thus fixing the side wall plate 3 to the tank foundation 1. After the pre-embedded reinforcing bars 2, side wall plate 3, water-stop steel plate 4, fastening angle steel 6, and fastening bolt 7 are all installed, secondary grouting slurry 5 is poured into the tank foundation 1. This multi-layered structure enhances the stability of the tank, strengthens the stability and sealing of the tank after secondary grouting, and extends the service life of the tank.
