Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to sewage treatment equipment with a self-cleaning function. Background Art

[0002] In today's society, with the rapid development of industry, especially the ferrous metal smelting industry, the amount of wastewater generated in its production process is increasing, and the composition of the wastewater is complex, containing a large number of harmful substances. Traditional sewage treatment equipment faces many challenges and can no longer meet the needs of efficient and environmentally friendly treatment.

[0003] In the sewage treatment process, the function of the medicine box is crucial. Traditional medicine boxes are usually fixed in a certain position and cannot be flexibly moved or adjusted in height. This leads to extremely uneven distribution of the reagents in the sewage, with excessive reagents in some areas causing waste and insufficient reagents in some areas affecting the treatment effect. For example, in the treatment of large sewage pools, it is difficult for fixed medicine boxes to cover every corner of the sewage pool, so that the pollutants in the sewage cannot fully react with the reagents, reducing the treatment efficiency and increasing the treatment cost.

[0004] Cleaning the dirt at the bottom of the sewage tank is also a major problem. Traditional equipment lacks an effective self-cleaning mechanism. The dirt accumulated at the bottom of the sewage tank for a long time will not only breed bacteria and corrode the equipment, but also hinder the flow of sewage and affect the normal operation of the equipment. Since there is no convenient cleaning method, it is often necessary to manually shut down the machine for cleaning regularly, which not only consumes a lot of manpower and material resources, but also frequently shuts down the machine and seriously affects production efficiency. In addition, manual cleaning cannot completely remove the dirt at the bottom, and the residual dirt will still have a negative impact on subsequent sewage treatment.

[0005] When the equipment is running, key components such as the medicine box lack effective protection. In a complex industrial environment, the medicine box is easily affected by external collisions, chemical corrosion and other factors, resulting in damage or failure. This not only increases the cost of equipment maintenance, but also affects the entire sewage treatment process due to equipment downtime maintenance, reduces the stability and reliability of the equipment, and shortens the service life of the equipment.

[0006] To sum up, the existing sewage treatment equipment has many shortcomings in terms of medicine box function, sewage tank bottom cleaning and equipment protection. In response to this, a sewage treatment equipment with self-cleaning function is proposed to improve the efficiency, quality and stability of sewage treatment. Summary of the invention

[0047] Please refer to the attached Figure 2 - Attachment Figure 4, since a linear slide 10 is fixed on the top of the sewage tank 1, a slider 2 is provided on the top of the linear slide 10, the top of the slider 2 is fixedly connected to the support frame 8, and limit blocks 15 for sliding up and down are provided on both sides of the support frame 8, and the two limit blocks 15 are connected by a support plate 29, one of the limit blocks 15 is connected to the medicine box 4 through a support rod, and the support frame 8 is driven to move by the slider 2 on the linear slide 10, thereby driving the medicine box 4 to move. During the movement, the medicine in the medicine box 4 flows to the nozzle at the bottom of the L-shaped plate 20 through the connecting pipe 21, and the medicine is sprayed into the sewage tank 1 through the nozzle, so as to realize the medicine treatment of the sewage, so as to realize the reciprocating movement of the medicine box 4 on the top of the sewage tank 1, and the flexible movement and height adjustment of the medicine box 4 enable the medicine to be evenly distributed in the sewage at different positions and depths. The distribution increases the contact area and mixing effect between the medicine and the sewage, and enhances the sewage treatment effect. The bottom of the support plate 29 is fixedly connected with a damping rod 17, and the bottom of the damping rod 17 is fixedly connected to the top of the slider 2. The outer wall of the damping rod 17 is sleeved with a spring 3; the top of the spring 3 is connected to the support plate 29, and the bottom of the spring 3 is connected to the outer wall of the damping rod 17, which plays a buffering role for the downward movement of the medicine box 4. Another limit block 15 is rotatably connected with a connecting plate 14, and the bottom end of the connecting plate 14 is rotatably connected with a support block, and the support block is located inside the guide groove 13 for sliding. The guide groove 13 is in the shape of a parallelogram and is provided on the side wall of the sewage tank 1 to change the moving height of the medicine box 4 in different moving directions. In addition, the side of the support block is rotatably connected with a roller 25 that rotates inside the guide groove 13;

[0048] Please see attached Figure 5 - Attachment Figure 7 A plurality of fixing frames 7 are arranged inside the profile bracket 5, and the fixing frames 7 are connected by protective profiles 6 to form a protective cover to protect the medicine box 4. A flap 16 is arranged inside the fixing frame 7, and the tops of the plurality of flaps 16 are connected by a rotating rod, and the bottoms of the plurality of flaps 16 are connected by a scraper. The end of the profile bracket 5 is connected to a plate 22, and the top of the outer flap 16 is connected to a split plate 18. Please refer to the attached Fig. 9, the dividing plate 18 is rotatably connected in the groove opened at the bottom end of the timing plate 22, the end of the timing plate 22 is fixedly connected with a sector gear 24, and the side wall of the end of the dividing plate 18 is fixedly connected with a sector gear 1 23 through an axis, and the sector gear 1 23 is located on the outside of the sector gear 24. The support frame will move downward first and then move horizontally under the limit of the guide groove 13. At the same time, the medicine box 4 and the support frame 8 move synchronously.

At the same time, this self-cleaning method reduces the frequency and difficulty of manual cleaning, reduces the equipment maintenance cost, and extends the service life of the equipment. When the flap 16 and the profile bracket 5 are folded, a protective cover is formed to form a protective cover to protect the medicine box 4.

[0049] Based on the above-mentioned sewage treatment equipment with self-cleaning function, its use method is as follows:

[0050] 1. Equipment installation and commissioning

[0051] S1. Install the sewage treatment equipment in a suitable position, and ensure that the sewage tank 1, medicine box 4, profile bracket 5 and other components are firmly installed and tightly connected. Check whether the linear guide rail 10, slider 2, guide groove 13 and other moving parts are smooth, and whether the damping rod 17, spring 2 and other buffer components are working properly;

[0052] S2, inject an appropriate amount of sewage treatment agent into the medicine box 4, and check whether the connecting pipe 21, the nozzle and other spraying components are unobstructed to ensure that the agent can be sprayed normally;

[0053] S3. Turn on the power supply of the equipment, start the motor 12, check whether the auger conveying blade 27 can rotate normally, and observe the operating status of each component of the equipment to ensure that there is no abnormal noise and vibration.

[0054] 2. Wastewater injection and pretreatment

[0055] Sewage containing pollutants is introduced into the sewage tank 1 through a pipe. After the sewage enters the sewage tank 1, the dirt therein begins to settle to the bottom due to gravity. During the sewage sedimentation process, some large particles of dirt will slide along the landslide plate 28 on the inner wall of one side of the sewage tank 1 to the feed trough 11 opened on the inner wall of one side of the bottom, waiting for subsequent cleaning.

[0056] 3. Chemical spraying treatment

[0057] The medicine box 4 starts to move through the slider 2 on the linear slide rail 10; during the movement of the medicine box 4, the medicine inside it flows to the nozzles at the bottom of the L-shaped plates 20 on both sides of the bottom through the connecting pipe 21. According to the actual situation and treatment requirements of the sewage, the position of the nozzle is adjusted by adjusting the bolts between the telescopic frame 9 and the mounting profile 19 on the telescopic profile frame, so that the medicine can be accurately and evenly sprayed to various parts in the sewage tank 1, so as to achieve full mixing of the medicine and sewage, and start the sewage medicine treatment process.

[0058] 4. Automatic cleaning (self-cleaning process)

[0059] S10, when the medicine spraying process is completed, the driving component controls the medicine box 4 to start moving in the reverse direction. At this time, the support frame 8 first moves downward under the limiting effect of the guide groove 13. In this process, the medicine box 4 and the support frame 8 move synchronously, and the double tooth plates 26 fixed on the front and rear sides of the medicine box 4 move downward accordingly;

[0060] S20, when the double-toothed plate 26 moves downward, it drives the meshing sector gear 1 23 and sector gear 2 24 to rotate. Since the number of teeth of sector gear 24 is less than that of sector gear 1 23, the rotation speed of the end of the plate 22 is lower than the rotation speed of the end of the splitter plate 18. The plate 22 drives the profile bracket 5 to rotate, and the splitter plate 18 drives the flap 16 to start moving on the profile bracket 5, so that the flap 16 is unfolded on the profile bracket 5.

[0061] S30, as the medicine box 4 continues to move horizontally, the scraper at the bottom of the flap 16 scrapes the dirt at the bottom of the sewage tank 1 toward the feed trough 11. At the same time, the motor 12 is started to drive the auger conveying blade 27 to rotate, and the auger conveying blade 27 conveys the dirt in the feed trough 11 to the discharge port set at one side of the bottom of the sewage tank 1. By controlling the valve inside the discharge port, the dirt is discharged from the sewage tank 1, and the cleaning of the inner wall of the bottom of the sewage tank 1 is completed.

[0062] 5. Equipment maintenance and cleaning (regularly)

[0063] (1) Regularly check the operating conditions of each component of the equipment, including the motor 12, drive assembly, nozzle, auger conveyor blade 27, etc., to ensure their normal operation. Check whether the protective profile 6 is damaged. If damaged, replace it in time to ensure effective protection of the medicine box 4;

[0064] (2) Regularly clean the dirt and impurities that may remain on the sewage tank 1, medicine box 4 and other parts to prevent their accumulation and affect the performance of the equipment. At the same time, check and replenish the medicine in the medicine box 4 to ensure that there is enough medicine for the next sewage treatment;

[0065] (3) Clean and lubricate the moving parts of the equipment, such as the linear guide rail 10, the slider 2, the roller 25, etc., to ensure smooth movement, reduce wear, and extend the service life of the equipment. Check whether there is any debris in the guide groove 13. If there is any, clean it in time to ensure that the guide groove 13 functions normally.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
