[0016] 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.
[0017] Please see Figure 1-2 The present invention provides the following technical solution: an exhaust device for condensate air barrier, comprising an exhaust pipe 5, an air filter 4 disposed inside the upper end of the exhaust pipe 5, a flange 6 disposed at the bottom end of the exhaust pipe 5, a U-shaped water storage pipe 3 disposed on one side of the exhaust pipe 5, a drainage indicator component 1 disposed on one side of the U-shaped water storage pipe 3, and a cover 2 disposed at the upper end of the U-shaped water storage pipe 3.
[0018] Specifically, the drainage indicator component 1 includes a fastening bolt 11, a battery pack 12, an overflow pipe 13, a battery mounting bracket 14, a water tank 16, a float 17, an electrode plate 18, a warning light 19, a fixing plate 110, a buzzer 111, and a fixing ring 112. The U-shaped water storage pipe 3 is fitted with a fixing ring 112, and the upper end of the fixing ring 112 is penetrated by the fastening bolt 11. A fixing plate 110 is provided on one side of the fixing ring 112. A water tank 16 is provided at the upper end, a float 17 is provided inside the water tank 16, an electrode plate 18 is provided at the upper end of the float 17, a battery mounting bracket 14 is provided on one side of the upper end of the water tank 16, a battery pack 12 is provided inside the battery mounting bracket 14, a buzzer 111 is provided on one side of the bottom end of the battery mounting bracket 14, and a warning light 19 is provided on the other side of the bottom end of the battery mounting bracket 14. An overflow pipe 13 is provided on the side wall of the U-shaped water storage pipe 3 near the cover 2.
[0019] By adopting the above technical solution, in the sewage treatment process, the condensate tank is installed with the vent pipe 5 via flange 6, and then the air filter 4 is used to realize the function of air intake or exhaust. When the air filter 4 is blocked, the air pressure inside the vent pipe 5 increases, causing the water stored in the U-shaped water storage pipe 3 to move towards the cover 2. When the water flows, it can be discharged from the overflow pipe 13 into the water tank 16 for collection. When the water continues to flow out, the water level inside the water tank 16 rises and the float 17 rises under the action of buoyancy. The electrode plate 18 at the upper end of the float 17 moves upward and abuts against the bottom end of the conductive plate of the positive terminal of the battery pack 12. At this time, the circuit is connected, and the battery pack 12 supplies power to the warning light 19 and the buzzer 111. The warning light 19 lights up and the buzzer 111 sounds to remind the staff so that the staff can promptly discover the problem of the air filter 4 being blocked, improve the functionality of the equipment, ensure the convenience of condensate tank pressure relief, reduce the cost of use, and improve the effect of use.
[0020] Specifically, a baffle plate 15 is provided at the upper part of the inside of the water tank 16 corresponding to the overflow pipe 13.
[0021] By adopting the above technical solution, overflowing water is prevented from directly hitting the electrode plate 18 and causing it to become damp, thus improving the stability of the power supply.
[0022] Specifically, a guide seat is provided inside the water tank 16 on the side away from the baffle plate 15, and a connecting rod is provided between the float 17 and the electrode plate 18, with the connecting rod passing through the inside of the guide seat.
[0023] By adopting the above technical solution, the stability of the float 17 in floating is ensured, and the electrode plate 18 is prevented from becoming skewed.
[0024] Specifically, electrode 18, warning light 19 and buzzer 111 are electrically connected to the negative terminal of battery pack 12, and a conductive plate is electrically connected to the positive terminal of battery pack 12.
[0025] By adopting the above technical solution, it is ensured that the circuit can be connected after the electrode plate 18 contacts the conductive plate, thereby improving the quality of equipment use.
[0026] Specifically, the inside of the fixing ring 112 is equipped with an anti-slip sleeve corresponding to the U-shaped water storage pipe 3.
[0027] By adopting the above technical solution, the stability and firmness of the installation of the fixing ring 112 are ensured, and the strength of the equipment is improved.
[0028] In this utility model, the battery pack 12 is a previously disclosed technology, and the selected model is GS2054DH.
[0029] In this utility model, the warning light 19 is a prior art technology, and the selected model is BSZD81.
[0030] The buzzer 111 in this utility model is a previously disclosed technology, and the selected model is YS-PBZ14075.
[0031] The working principle and usage process of this utility model are as follows: During the sewage treatment process, the condensate tank is installed with the vent pipe 5 via flange 6, and then the air filter 4 is used to achieve the function of air intake or exhaust. When the air filter 4 becomes clogged, the air pressure inside the vent pipe 5 increases, causing the water stored in the U-shaped water storage pipe 3 to move towards the cover 2. When the water flows, it can be discharged from the overflow pipe 13 into the water tank 16 for collection. When the water continues to flow out, the water level inside the water tank 16 rises, and the float 17 rises under the buoyancy of the water. The electrode plate 18 at the upper end of the float 17 moves upward and abuts against the bottom end of the conductive plate of the positive terminal of the battery pack 12. At this time, the circuit is connected, and the battery pack 12 supplies power to the warning light 19 and the buzzer 111. The warning light 19 illuminates, and the buzzer 111 sounds to remind the staff so that the staff can promptly detect the problem of the air filter 4 being clogged, thereby improving the functionality of the equipment, ensuring the convenience of condensate tank depressurization, reducing the cost of use, and improving the effect of use.
