[0022] 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.

[0023] Please see Figure 1-4This utility model provides a technical solution: a refining furnace water treatment and sewage discharge device, including a water tank 1, a sewage pipe 2 fixedly connected to the lower surface of the water tank 1, a sewage valve 3 fixedly connected to one side surface of the sewage pipe 2, a connecting pipe 4 fixedly connected to one end surface of the sewage pipe 2, a main sewage valve 5 installed on one side surface of the connecting pipe 4, a main sewage pipe 6 fixedly connected to one end surface of the connecting pipe 4, a sewage outlet 7 opened on one end surface of the main sewage pipe 6, a sealing mechanism 8 provided on the lower surface of the water tank 1, and an anti-blocking mechanism 9 provided on the inner surface of the water tank 1. Through the arrangement of the water tank 1, sewage pipe 2, sewage valve 3, connecting pipe 4, main sewage valve 5, main sewage pipe 6, and sewage outlet 7, the water tank 1 can independently... The supply and return water pipes are connected separately. The supply water pipes for the refining furnace and the refining furnace are connected using a pressurized tap. The return water pipes are connected in the same way. The two supply water pipes are merged into one supply water pipe, and the two return water pipes are also merged into one return water pipe, connecting the two water tanks 1. Water tank 1 is full of water under normal production conditions, and it is not possible to connect them by drilling holes and burying pipes in water tank 1. The connection of water tank 1 can only be achieved by using the sewage pipe 2 at the bottom of water tank 1. The two sewage branch pipes that independently discharge sewage to the sewage main pipe 6 are cut and connected together. Then, the connecting pipe 4 and sewage pipe 2 are connected to the sewage main pipe 6. A DN300 manual valve is installed on the pipe between the sewage connecting pipe 4 and the sewage main pipe 6. Open the original independent manual drain valve of the second water tank 1, and close the newly installed common drain valve 5 of the second water tank 1. Connect the bottoms of the two independent water tanks 1 using the newly installed drain connecting pipe 4. Adjust the water flow of the return water pipe of the second water tank 1. There are two return water pipes and one return water pipe of the second water tank 1. The return water flow to the two water tanks 1 differs significantly from the outgoing water flow, and the DN300 connecting pipe 4 connecting the two water tanks 1 can only balance a small amount of water. First, adjust the return water inlet valve of the second water tank 1 to achieve a basic balance between the outgoing and return water flow of each water tank 1. Then, use the connecting pipe 4 of the second water tank 1 to make the water level of the two water tanks 1 consistent.

[0024] The sealing mechanism 8 includes a fixing member 801, a retaining ring 802, a receiving groove 803, a threaded groove 804, a sealing ring 805, a threaded interface 806, and a sealing sleeve 807. The fixing member 801 is installed on the lower surface of the water tank 1. The retaining ring 802 is fixedly connected to the outer surface of the fixing member 801. The receiving groove 803 and the threaded groove 804 are both located on the inner surface of the fixing member 801. The sealing mechanism 8 connects the fixing member 801, the retaining ring 802, and the receiving groove 804. The groove 803, threaded groove 804, sealing ring 805, threaded interface 806, and sealing sleeve 807 are configured so that the threaded interface 806 at one end of the sewage pipe 2 is installed into the fixing part 801 at the bottom of the water tank 1. The threaded interface 806 matches the threaded groove 804. The sealing ring 805 is installed in the receiving groove 803 on the inner side of the fixing part 801 to prevent sewage leakage. After the connection is completed, the sealing sleeve 807 is fitted between the outer retaining rings 802 for further sealing.

[0025] Furthermore, the anti-clogging mechanism 9 includes a drain outlet 901, a placement plate 902, a motor 903, a rotating rod 904, a threaded plate 905, a protective shell 906, and a heat dissipation hole 907. A drain outlet 901 is provided on the inner surface of the water tank 1. A placement plate 902 is fixedly connected to one side surface of the water tank 1. A motor 903 is placed on the upper surface of the placement plate 902, and a rotating rod 904 is installed on the lower surface of the motor 903. The mechanism utilizes the drain outlet 901, placement plate 902, motor 903, and rotating rod 907. 4. The installation of threaded plate 905, protective shell 906 and heat dissipation hole 907: A placement plate 902 is installed above the water tank 1. When discharge is required, the motor 903 above the placement plate 902 is started. The motor 903 drives the rotating rod 904 to rotate the threaded plate 905, so that the impurities accumulated around the drain outlet 901 are sucked in and discharged through the drain pipe 2. The protective shell 906 protects the motor 903, and at the same time, the heat dissipation hole 907 above dissipates the heat generated by the motor 903.

[0026] Furthermore, a sealing ring 805 is fixedly connected to the inner surface of the storage tank 803, a threaded interface 806 is installed on one end surface of the drain pipe 2, and a sealing sleeve 807 is fitted on the outer surface of the drain pipe 2. By setting the storage tank 803, the sealing ring 805 is installed inside, thereby preventing wastewater leakage.

[0027] Furthermore, a threaded plate 905 is fixedly connected to the outer surface of the rotating rod 904, and a protective shell 906 is installed on the upper surface of the placement plate 902. A heat dissipation hole 907 is opened on the upper surface of the protective shell 906. Through the setting of the threaded plate 905, excessive waste can be sucked into the drain pipe 2 for discharge.

[0028] Furthermore, the sewage pipe 2 is installed symmetrically with respect to the central axis of the connecting pipe 4, and the sewage valve 3 is installed symmetrically with respect to the central axis of the connecting pipe 4. The sewage discharge volume is controlled by the sewage valve 3.

[0029] Furthermore, the sewage pipe 2 and the connecting pipe 4 are the same size, and the sealing ring 805 is made of fluororubber. Through the setting of the connecting pipe 4, the sewage generated by the two pools 1 are collected and discharged in a unified manner.

[0030] Furthermore, the motor 903 is installed between the two placement plates 902, and the outer surface dimension of the threaded plate 905 matches the inner surface dimension of the drain outlet 901. Through the setting of the motor 903, the rotating rod 904 can be driven to work.

[0031] Furthermore, the outer surface dimensions of the sealing ring 805 match the inner surface dimensions of the receiving groove 803, and the threaded interface 806 and the threaded groove 804 form a threaded structure. Through the setting of the threaded interface 806, the drain pipe 2 is connected to the water tank 1.

[0032] Furthermore, retaining rings 802 are respectively installed on the fixing member 801 and the threaded interface 806, and sealing sleeves 807 are fitted between retaining rings 802. The sealing sleeves 807 are used to further seal and prevent sewage leakage.

[0033] Furthermore, the rotating rod 904 and the threaded plate 905 form a rotating structure, and the heat dissipation holes 907 are evenly distributed on the upper surface of the protective shell 906. Through the setting of the heat dissipation holes 907, the heat generated by the motor 903 during operation is dissipated.

[0034] Working principle: First, the independent supply and return water pipes are connected. The supply water pipes for the refining furnace are connected using a pressurized tap. The return water pipes are connected in the same way. The two supply water pipes are merged into one supply water pipe, and the two return water pipes are also merged into one return water pipe, connecting the two water tanks 1. Under normal production conditions, water tank 1 is full of water, and it is not possible to connect it by drilling holes and burying pipes in water tank 1. Only by using the sewage pipe 2 at the bottom of water tank 1 can water tank 1 be connected. The two sewage branch pipes that independently discharge sewage to the sewage main pipe 6 are cut and connected together. Then, the connecting pipe 4 and sewage pipe 2 are connected to the sewage main pipe 6. A DN300 manual valve is installed on the pipe between the sewage connecting pipe 4 and the sewage main pipe 6. Open the original independent manual drain valve of the second water tank 1, close the newly installed common drain valve 5 of the second water tank 1, and connect the bottom of the two independent water tanks 1 using the newly installed drain connecting pipe 4. Adjust the water volume of the return water pipe of the second water tank 1. There are two return water pipes of the second water tank 1 and one return water pipe of the second water tank 1. The return water volume to the two water tanks 1 is significantly different from the outgoing water volume, and the DN300 connecting pipe 4 connecting the second water tank 1 can balance the relatively small amount of water. First, adjust the return water inlet valve of the second water tank 1 to achieve a basic balance between the outflow and return water volumes of each water tank 1. Then, connect the two water tanks 1 through the connecting pipe 4 to ensure that the water levels in the water tanks 1 are consistent. Install the threaded interface 806 at one end of the drain pipe 2 into the fixing part 801 at the bottom of the inlet water tank 1. The threaded interface 806 matches the threaded groove 804. A sealing ring 805 is installed in the receiving groove 803 inside the fixing part 801 to prevent sewage leakage. After the connection is completed, a sealing sleeve 807 is fitted between the outer retaining rings 802 for further sealing. A placement plate 902 is installed above the water tank 1. When discharge is required, start the motor 903 above the placement plate 902. The motor 903 drives the rotating rod 904 to rotate the threaded plate 905, causing the impurities accumulated around the drain outlet 901 to be sucked in and discharged through the drain pipe 2. The protective shell 906 protects the motor 903, and the heat dissipation hole 907 on top dissipates the heat generated by the motor 903.
