Detailed Implementation
[0020] 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.
[0021] Please refer to Figures 1-4. This utility model provides a technical solution: a tannery wastewater neutralization device, including a neutralization tank 1, a dual-head motor 2, a discharge pipe 3, heat dissipation fins 4, a stirring rod 5, a transmission ring 6, a transmission frame 7, fan blades 8, an exhaust pipe 9, activated carbon cotton 10, an exhaust pipe 11, an end cap 12, a sealing gasket 13, a sealing mechanism 14, a bracket 1401, a pull rod 1402, a sealing cover 1403, and a spring 1404. A dual-head motor 2 is installed at one end of the neutralization tank 1, and a discharge pipe 3 is provided at the lower end of the other end of the neutralization tank 1. A stirring rod 5 is fixedly connected to the end of the output shaft, and a transmission ring 6 is movably installed on the outer wall of the neutralization tank 1 near the end of the dual-head motor 2. At the same time, a fan blade 8 is fixedly connected to the outer wall of the transmission ring 6. An exhaust pipe 9 is installed through the upper end of the neutralization tank 1, and activated carbon cotton 10 is movably connected to the inner wall of the exhaust pipe 9. An exhaust pipe 11 is fixedly installed through the upper end of the side of the exhaust pipe 9, and an end cap 12 is fitted on the outer wall of the upper end of the exhaust pipe 9. At the same time, a sealing gasket 13 is adhered to the inner wall of the end cap 12. A sealing mechanism 14 is provided on the outer wall of the exhaust pipe 9 below the exhaust pipe 11.
[0022] The neutralization tank 1 and the stirring rod 5 are rotatable, and the outer wall of the neutralization tank 1 is fixedly connected with heat dissipation fins 4, which facilitates the rotation of the stirring rod 5 by the dual-head motor 2, so that the materials inside the device are mixed, thereby ensuring the neutralization effect of the tanning wastewater, and increasing the heat dissipation area of the neutralization tank 1 through the heat dissipation fins 4, thereby ensuring the heat dissipation effect of the device.
[0023] The outer wall of the output shaft of the dual-head motor 2 is connected to the transmission frame 7 and the transmission ring 6. The transmission ring 6 and the neutralizing barrel 1 form a rotating structure, which makes it easy for the dual-head motor 2 to drive the transmission frame 7 to rotate, so that the transmission frame 7 drives the transmission ring 6 to rotate relative to the neutralizing barrel 1, thereby causing the fan blade 8 to rotate and blow air towards the neutralizing barrel 1 for air cooling.
[0024] The vent pipe 9 and the activated carbon cotton 10 are slidably connected, and both the vent pipe 9 and the activated carbon cotton 10 are in contact with the sealing gasket 13. The vent pipe 9 and the end cap 12 are threadedly connected, which makes it convenient for the user to insert the activated carbon cotton 10 into the vent pipe 9, and then put the end cap 12 on the vent pipe 9 and tighten the end cap 12. This makes the sealing gasket 13 fit the vent pipe 9 and the activated carbon cotton 10, thereby sealing the vent pipe 9 and limiting the activated carbon cotton 10.
[0025] The sealing mechanism 14 includes a bracket 1401, a pull rod 1402, a sealing cover 1403, and a spring 1404. The bracket 1401 is movably installed on the outer wall of the outlet pipe 9, and the pull rod 1402 is movably connected to the inner wall of the end of the bracket 1401. The sealing cover 1403 is fixedly installed at the lower end of the pull rod 1402, so as to facilitate the sealing of the neutralization tank 1 by the sealing mechanism 14, thereby ensuring that the waste gas in the neutralization tank 1 is discharged from the device through the outlet pipe 9 and the exhaust pipe 11.
[0026] The bracket 1401 and the vent pipe 9 are rotatable, and the bracket 1401 and the pull rod 1402 form a sliding structure. The sealing cover 1403 and the neutralization container 1 are slidable, and the upper surface of the sealing cover 1403 is connected to the lower surface of the bracket 1401 through the spring 1404, so that the user can pull the pull rod 1402 to move the pull rod 1402 upward relative to the bracket 1401. At this time, the sealing cover 1403 moves upward and compresses the spring 1404. Thus, when the user pulls the bracket 1401 to rotate relative to the vent pipe 9, so that the sealing cover 1403 and the neutralization container 1 are aligned, the user releases the pull rod 1402, allowing the spring 1404 to return to its original position and push the sealing cover 1403 downward, so that the sealing cover 1403 is stably inserted into the neutralization container 1 to complete the sealing of the neutralization container 1.
[0027] Working principle: When using this tannery wastewater neutralization device, as shown in Figure 1-4, the user first inserts the activated carbon cotton 10 into the vent pipe 9. Then, the user places the end cap 12 onto the vent pipe 9 and tightens it. Next, the end cap 12 drives the sealing gasket 13 to adhere to the vent pipe 9 and the activated carbon cotton 10, thus completing the installation of the activated carbon cotton 10. Then, the user pours the tannery wastewater and neutralizing agent into the neutralization tank 1. Next, the user pulls the lever 1402, causing the lever 1402 to move upwards relative to the bracket 1401. At this time, the lever 1402 drives the sealing cap... 1403 moves upward, and the sealing cap 1403 compresses the spring 1404, causing deformation. Next, the user pulls the bracket 1401 to rotate relative to the vent pipe 9. Subsequently, the bracket 1401 drives the sealing cap 1403 to move, aligning the sealing cap 1403 with the neutralization tank 1. Then, the user releases the pull rod 1402, at which point the spring 1404 returns to its original position, pushing the sealing cap 1403 downward so that it is stably inserted into the neutralization tank 1, thus completing the sealing of the neutralization tank 1. Then, the user starts the dual-head motor 2, which drives the stirring rod 5 to rotate. Next, stirring rod 5 thoroughly stirs the materials in neutralization tank 1, allowing the tanning wastewater and neutralizing agent to mix fully for neutralization treatment. When waste gas is generated during the neutralization of the tanning wastewater, the waste gas is discharged from the device through outlet pipe 9 and exhaust pipe 11. As the waste gas flows through outlet pipe 9, activated carbon cotton 10 purifies the waste gas. Therefore, the device facilitates the treatment of neutralized waste gas, thereby avoiding environmental pollution and improving the environmental friendliness of the device. Heat is easily released during wastewater neutralization; at this time, the dual-head motor 2 drives the transmission frame 7 to rotate. Then, the transmission frame 7 drives the transmission ring 6 to rotate, and the transmission ring 6 drives the fan blade 8 to rotate. Subsequently, the fan blade 8 blows air onto the surface of the neutralization barrel 1, thereby cooling the neutralization barrel 1. At the same time, the heat dissipation fins 4 increase the heat dissipation area of the neutralization barrel 1, thereby further improving the heat dissipation effect of the device and preventing heat from accumulating on the device and affecting the neutralization process, thus improving the practicality of the device. Finally, after the tannery wastewater is treated, the user turns off the dual-head motor 2 and opens the discharge pipe 3. At this time, the material inside the device is discharged from the device through the discharge pipe 3.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
