Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment device with zero discharge of industrial wastewater. Background Technology

[0002] Zero wastewater discharge refers to the recycling and reuse of wastewater after industrial water use. Typically, wastewater treatment equipment is used to filter impurities from the wastewater, and the filtered water is then reused in industrial production, improving water resource utilization while protecting the environment.

[0003] In the prior art, patent publication number CN218434947U describes a wastewater treatment device based on zero discharge of industrial wastewater. When using this patent, the industrial wastewater to be treated is poured into a storage tank. Because the storage tank, first filter box, second filter box, and third filter box are stacked from top to bottom, the wastewater will be filtered layer by layer under gravity, eventually falling into a sedimentation tank. Chemicals can then be added to the sedimentation tank. After reaction, the precipitate is discharged from the bottom of the sedimentation tank, and the supernatant is discharged from the discharge pipe. During the treatment process, the motor is controlled to operate. It can drive the rotating rod to rotate, which in turn drives the stirring plate and the auger to rotate. The stirring plate can scrape off the impurities deposited on the surface of the first filter hole, and the auger can turn the bottom impurities upward, thus avoiding the blockage of the first filter hole and improving the efficiency of sewage treatment. However, in actual use, there are still the following shortcomings: In practice, when the device treats sewage, the bottom sediment is difficult to completely discharge during discharge, affecting the sewage treatment effect. Moreover, when filtering sewage, it is difficult to replace and disassemble the filter plate, which reduces the practicality of the device and increases the complexity of operation.

[0004] Therefore, there is a need for a wastewater treatment device with zero discharge of industrial wastewater to solve the problem in existing technologies where bottom sediment is difficult to completely remove during discharge, thus affecting the wastewater treatment effect.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5 This utility model provides a wastewater treatment device for zero discharge of industrial wastewater, including a tank 1, a stirring mechanism 2, a reaction chamber 3, a filtration mechanism 4, an inlet pipe 5, and an outlet pipe 6. The reaction chamber 3 is arranged at the upper part of the tank 1, the stirring mechanism 2 is arranged inside the reaction chamber 3, the treatment chamber is arranged below the reaction chamber 3, the filtration mechanism 4 is arranged inside the treatment chamber, the inlet pipe 5 is fixedly connected to one side of the reaction chamber 3, and the outlet pipe 6 is arranged on the lower side of the treatment chamber.

[0025] The filtration mechanism 4 consists of a mounting frame 401, a positioning component 402, a filter plate 403, a baffle 404, a sealing ring 405, and a slide bar 406. The positioning component 402 is symmetrically arranged around the top of the mounting frame 401. The filter plate 403 is mounted on the top of the mounting frame 401 through the positioning component 402. The baffle 404 is fixedly connected to the front of the positioning component 402. The sealing ring 405 is fixedly connected to the outside of the baffle 404. The slide bar 406 is symmetrically fixedly connected to the left and right sides of the mounting frame 401, and the interior of the processing chamber is provided with a sliding groove that matches the slide bar 406.

[0026] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that a rectangular groove adapted to the baffle 404 is provided on the front of the processing chamber, and the sealing ring 405 is completely fitted inside the rectangular groove.

[0027] The sealing ring 405 prevents sewage from flowing out of the treatment chamber, ensuring the airtightness of the tank 1 and improving the treatment effect.

[0028] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the positioning component 402 consists of a fixing block 4021, a connecting plate 4023, a slider 4024, a positioning block 4025, a spring 4026, a push plate 4027, and a limiting rod 4028. The fixing block 4021 is fixedly connected to the top of the mounting frame 401, and the filter plate 403 has a through groove adapted to the fixing block 4021. The top surface of the fixing block 4021 has a groove 4022, the connecting plate 4023 is disposed inside the groove 4022, the slider 4024 is fixedly connected to the bottom surface of the connecting plate 4023, and the positioning block 4025 is fixedly connected to one side of the connecting plate 4023. The positioning block 4025 slides between the groove 4022 and the outer surface of the fixing block 4021. The bottom surface of the groove 4022 has a guide groove adapted to the slider 4024.

[0029] By allowing the slider 4024 to slide inside the guide groove, the stability of the sliding of the connecting plate 4023 can be ensured, and the stability of the movement of the positioning block 4025 can be improved.

[0030] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the spring 4026 is fixedly connected between the other side of the connecting plate 4023 and the side of the groove 4022, the push plate 4027 is fixedly connected to the top surface of the connecting plate 4023, and the limiting rod 4028 is rotatably connected to the top of the fixing block 4021.

[0031] When the filter plate 403 needs to be installed, it is fitted onto the outside of the fixing block 4021 through the through groove of the filter plate 403. Then, the limiting rod 4028 is rotated to release the limiting of the push plate 4027. Through the elastic action of the compressed spring 4026, the connecting plate 4023 is driven to reset, so that the positioning block 4025 extends out of the fixing block 4021 and limits and fixes the filter plate 403 below, thereby completing the installation of the filter plate 403.

[0032] As can be seen from the above working process, the wastewater after the reaction can be filtered through the filter mechanism 4. The positioning component 402 allows users to quickly disassemble, clean, or replace the filter plate 403. The structure is simple and the operation is convenient, which improves the filtration effect and flexibility of the device.

[0033] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the stirring mechanism 2 consists of a motor 201, a connecting shaft 202, a driving gear 203, a driven gear 204, a rotating shaft 205, and a stirring rod 206. The motor 201 is fixedly connected to the top of the housing 1, the connecting shaft 202 is connected to the output end of the motor 201, the driving gear 203 is fixedly connected to the outside of the connecting shaft 202, and the driven gears 204 are symmetrically arranged on the outside of the driving gear 203. There are three driven gears 204, and each driven gear 204 meshes with the driving gear 203.

[0034] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the rotating shaft 205 passes through the interior of the driven gear 204 and is fixedly connected to the driven gear 204. The stirring rods 206 are evenly fixedly connected to the outside of the connecting shaft 202 and the rotating shaft 205 respectively. The stirring rods 206 outside the rotating shaft 205 are staggered from the stirring rods 206 outside the connecting shaft 202.

[0035] By using staggered stirring rods 206, the efficiency of stirring wastewater and chemicals can be increased, and the uniformity and effect of stirring can be improved.

[0036] The working process of this solution is as follows: In use, sewage is first transported into the reaction chamber 3 through the inlet pipe 5, and then the reaction agent is added into the sewage through the inlet pipe on the other side. Then, the motor 201 is started to drive the connecting shaft 202 to rotate. The driving gear 203 drives the other three driven gears 204 to rotate, thereby driving the rotating shaft 205 to rotate at the same time. The stirring rod 206 on the outside of the connecting shaft 202 rotates at the same time as the stirring rod 206 on the outside of the rotating shaft 205, and the sewage and the agent are stirred alternately to improve the stirring uniformity and reaction efficiency. The harmful substances in the wastewater are reacted and agglomerated into large particles. Then, the control valve below the reaction chamber 3 is opened to let the wastewater containing large particles flow into the treatment chamber below. It is filtered through two layers of filter plates 403 in sequence. The filtered water is discharged through the outlet pipe 6.

[0037] When it is necessary to clean the impurities on the filter plate 403, pull the handle on the front of the baffle 404 to pull the mounting frame 401 outward. The mounting frame 401 slides smoothly through the slide bar 406 inside the slide groove. Then clean the impurities on the filter plate 403. After cleaning, the filter plate 403 can be repaired or replaced as needed. First, push the push plate 4027 to drive the positioning block 4025 to fully retract into the groove 4022 through the connecting plate 4023. At the same time, the spring 4026 is squeezed, and the limit rod 4028 is rotated in the opposite direction, so that the limit rod 4028 falls in the reset direction of the push plate 4027. This restricts the connecting plate 4023 from resetting with the elastic action of the spring 4026, making it convenient for the user to remove the filter plate 403 from the outside of the positioning assembly 402, and to facilitate deep cleaning and replacement of the filter plate 403.

[0038] In summary: The stirring mechanism 2 allows a motor 201 to drive the connecting shaft 202 and the other three rotating shafts 205 to rotate simultaneously. The staggered stirring rods 206 rapidly stir the wastewater and the reagent, promoting a mixing reaction and improving stirring efficiency and reaction effect. The filtration mechanism 4 filters the wastewater after the reaction. The positioning component 402 allows users to quickly disassemble, clean, or replace the filter plate 403. The device has a simple structure, is easy to operate, and improves the filtration effect and flexibility of use.
