Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field especially relates to a grey water treatment's mechanical mud scraping clarifier. BACKGROUND

[0002] The fertilizer production process covers key links such as raw material processing, synthetic ammonia preparation, urea synthesis, and a large amount of industrial wastewater is generated in the process. Such wastewater not only contains pollutants such as reaction residues, suspended solids and colloidal particles, but also contains hard particles such as ore debris and metal impurities left over from the raw material mining and processing stages. If it is directly discharged into the subsequent water treatment unit or discharged, it will seriously affect the treatment efficiency, cause environmental pollution, and even cause equipment failure. The clarifier integrates coagulation, flocculation and sedimentation processes, which can efficiently separate solid and liquid in the fertilizer production wastewater: by adding clarifying agents, the suspended solids and colloidal particles in the wastewater react with the agents to form flocs, and by the adsorption and retention of the suspended sludge layer, the pollutants in the wastewater are greatly removed, the wastewater turbidity and pollutant load are reduced, and stable conditions are created for subsequent neutralization, filtration and other deep treatment links, avoiding blockage or corrosion of subsequent equipment by pollutants. At the same time, according to the characteristics of the fertilizer production wastewater, the clarifier's mud scraping system can timely remove the impurities and sludge deposited at the bottom of the pool, ensuring the continuity and stability of the wastewater treatment. In addition, under the background of environmental protection compliance and sustainable operation in fertilizer production, the clarifier can effectively reduce the pollutant content of wastewater, help wastewater discharge in accordance with standards, and reduce environmental risks. It is a key facility for fertilizer production enterprises to implement environmental protection requirements and achieve clean production, and its operation effect directly affects the environmental protection and economy of the fertilizer production process, so it has become an indispensable core component of the wastewater treatment system in the fertilizer production field.

[0003] The existing mud scraping mechanism configured at the bottom of the clarifier, in the process of circulating movement according to the preset trajectory to scrape mud, it is difficult to completely intercept large-volume hard impurities such as stones, iron wires and metal debris at the water inlet end of the clarifier. Such impurities are easy to settle with suspended solids to the bottom of the pool and accumulate on the mud scraping path. A certain gap is required between the scraper and the clarifier bottom plate to ensure smooth movement of the mud scraping mechanism. These hard impurities are easily stuck in the gap, forming rigid jamming. The instantaneous impact force generated by the jamming will cause local overload of the scraper, resulting in scratches, deformation or even wear and tear. On the other hand, the jamming will cause the load of the driving motor to increase suddenly, which will trigger the protection shutdown to interrupt the mud scraping operation, or damage the transmission components, thereby not only destroying the continuity of the mud scraping and reducing the efficiency of the pool bottom sludge cleaning, but also requiring frequent shutdown and disassembly to clean the impurities, greatly increasing the operation and maintenance cost, and long-term repeated jamming will also shorten the overall service life of the mud scraping mechanism, thereby affecting the stable operation of the clarifier and the sewage purification effect.

[0030] Please refer to Figure 3 As shown, the outside of preliminary cleaning assembly 5 is provided with clarifying baffle 8, the top end between clarifying baffle 8 and support cylinder 2 outer wall is fixedly connected, the bottom end of clarifier body 1 is fixedly connected with clarifying bottom plate 16, the bottom end between clarifying baffle 8 and the inner wall of clarifying bottom plate 16 is fixedly connected, and clarifying cavity is formed, the side of clarifier body 1 is fixedly connected with inlet pipe 10, and the output end of inlet pipe 10 is communicated with clarifying cavity, the bottom end of clarifying bottom plate 16 is fixedly connected with sludge discharge pipe 12, the outside of support cylinder 2 is fixedly connected with water discharge baffle 17, the outer ring opening between water discharge baffle 17 and the inner wall of clarifier body 1 is fixedly connected, and water discharge cavity is formed, the top of support cylinder 2 is provided with water outlet slot 14 at equal intervals, the inner cavity of support cylinder 2 is communicated with water discharge cavity through water outlet slot 14, the side of clarifier body 1 away from inlet pipe 10 is fixedly connected with water outlet pipe 11 and dosing pipe 13, the input end of water outlet pipe 11 is communicated with water discharge cavity, and the output end of dosing pipe 13 is communicated with clarifying cavity.

[0031] The mud scraping mechanism configured at the bottom of the existing clarifier, in the process of circulating movement and scraping mud according to the preset track, because the water inlet end of the clarifier is difficult to completely intercept the hard impurities such as stones, iron wires and metal scraps with relatively large volume, if such impurities directly contact the scraper, a relatively large scraping pressure is caused to the scraper, and once the impurities are clamped into the gap between the scraper and the bottom of the pool, the scraper is also easily clamped, in order to solve this technical problem, the present application is improved as follows:

[0032] Please refer to Figure 4 As shown, the bottom end of rotating shaft 3 is installed with rotating assembly 4, rotating assembly 4 includes fixedly connected with the bottom end of rotating shaft 3 shielding block 401, the bottom of shielding block 401 is fixedly connected with sludge discharge cavity 402, and a plurality of sludge inlets 403 are arranged at equal intervals in the inside of sludge discharge cavity 402, the outer wall top of sludge discharge cavity 402 is fixedly connected with annular sliding groove 404;

[0033] The primary cleaning assembly 5 is arranged at the position of the mud inlet 403, and the primary cleaning assembly 5 comprises a support rod 501, and a plurality of cleaning teeth 502 are arranged at the bottom of the support rod 501 at equal intervals, and the cleaning teeth 502 form a tooth groove between each group of cleaning teeth 502. The primary cleaning assembly 5 is arranged at the front of the mud scraping assembly 6 according to the rotating direction of the rotating assembly 4. The grid structure formed by each group of cleaning teeth 502 is used to scan the bottom of the pool first, and is used to scrape some hard impurities such as stones, iron wires and metal scraps with large volume on the bottom of the pool;

[0034] The grid structure is used to scan the bottom of the pool first, and each group of cleaning teeth 502 can accurately intercept hard impurities such as stones and iron wires with large volume. The rigid frame structure has stronger impact resistance and wear resistance, and can directly strip the hard impurities from the bottom of the pool and collect them in the mud discharge cavity 402 during the pre-scraping process, so that the impurities cannot enter the working path of the subsequent mud scraping assembly 6, and cannot be stuck in the gap between the cleaning scraper 601 and the pool bottom plate. Therefore, the wear of the scraper, the overload shutdown of the motor and the damage risk of the transmission parts caused by the hard impurities are fundamentally eliminated, and the equipment failure probability and the operation and maintenance cost are greatly reduced.

[0035] Please refer to Figure 1 、 Figure 5 and Figure 6 , the mud scraping assembly 6 is arranged on the outer wall of the mud discharge cavity 402, and the cleaning scraper 601 is fixedly connected to the outer wall of the mud discharge cavity 402. The cleaning scraper 601 is used to scan the bottom of the pool and is used to scrape and clean the mud above again. After the pre-cleaning teeth 502 complete the separation and removal of the hard impurities, the subsequent cleaning scraper 601 can run on the clean path without foreign matter interference, can completely scrape the mud close to the bottom of the pool, avoids the residual mud caused by the impurities, and improves the mud scraping efficiency and the cleanliness of the pool bottom.

[0036] Please refer to Figure 5 , the end of the support rod 501 is rotatably connected with a shaft-shaped sliding block 503, the shaft-shaped sliding block 503 is slidably connected to the inside of the annular sliding groove 404, the back of the support rod 501 is fixedly connected with a spring steel sheet 504, one end of the spring steel sheet 504 away from the support rod 501 is fixedly connected with a fixed block 505, the fixed block 505 is fixedly connected to the inside of the annular sliding groove 404, the bottom of the cleaning scraper 601 is fixedly connected with a cleaning thimble 602, and the tooth groove between the cleaning thimble 602 and the cleaning teeth 502 corresponds one by one.

[0037] When the cleaning tooth 502 encounters a jamming situation, the spring steel sheet 504 can be compressed backward to buffer, avoiding damage such as deformation and fracture of the cleaning tooth 502 due to rigid collision, and the relative displacement between the cleaning tooth 502 and impurities in the buffering process can reduce the fastening degree of jamming and the damage of impurities, thereby protecting the structure of the cleaning tooth 502 and the driving components; at the same time, the rotating assembly 4 with the mud scraping assembly 6 continues to move forward, so that the cleaning needle 602 is inserted into the tooth groove of the cleaning tooth 502 for cleaning, and the impurities jammed in the tooth groove are actively cleaned, which not only solves the problem of tooth groove jamming of the cleaning tooth 502 itself, but also quickly restores the normal sweeping and scraping function of the cleaning tooth 502 without the need to stop and disassemble for cleaning; the self-repairing ability of the mud scraping system in response to jamming is improved, the frequency of shutdown maintenance is reduced, the continuity of mud scraping operation is ensured, and the service life of the core components such as the cleaning tooth 502 and the cleaning scraper 601 is further prolonged, thereby ensuring stable and efficient operation of the mud scraping system of the clarifying tank.

[0038] As shown in Figure 4 The shape of the shielding block 401 is conical, and the upper mud can move downward to prevent the accumulation of mud above the shielding block 401. The bottom diameter of the shielding block 401 is larger than the diameter of the ring-shaped chute 404, so as to shield and protect the ring-shaped chute 404.

[0039] As shown in Figure 7 The support cylinder 2 is further provided with a filtering assembly 7. The filtering assembly 7 comprises a filter plate 701 fixedly connected to the inside of the support cylinder 2, and the rotating shaft 3 is rotatably connected to the filter plate 701. The filtering assembly 7 further comprises a mounting rod 702 fixedly connected to the outer wall of the rotating shaft 3. The bottom of the mounting rod 702 is fixedly connected with a cleaning brush 703, and the bottom surface of the cleaning brush 703 sweeps over the top surface of the filter plate 701. When the rotating shaft 3 rotates, the mounting rod 702 and the cleaning brush 703 rotate together to clean the top surface of the filter plate 701 and prevent it from being blocked.

[0040] Working principle: wastewater that needs to be clarified is transported into the clarification cavity inside the clarification baffle 8 through the water inlet pipe 10, and the clarification agent is also put into the clarification cavity through the dosing pipe 13. After reaction and sedimentation in the clarification baffle 8, the sludge is deposited at the bottom of the cavity, and the clear water is located above and enters the support cylinder 2 above through the filtering of the filtering assembly 7, and then enters the drainage cavity through the water outlet slot 14, and finally is extracted outside by the water outlet pipe 11.

[0041] When the sludge on the pool bottom is scraped, the output shaft of the driving motor 15 drives the rotating assembly 4 to rotate through the rotating shaft 3, and simultaneously drives each group of primary cleaning assemblies 5 and the scraping assembly 6 to rotate on the pool bottom. The cleaning teeth 502 are used for primary cleaning of the pool bottom, and scrape some large stone blocks and other impurities. The subsequent cleaning scraper 601 is used for secondary scraping and cleaning of the pool bottom, and is used for scraping some sludge. The scraped stone blocks and sludge move to the bottom of the inclined surface of the clarifying bottom plate 16 along the inclined surface, and are discharged outward through the sludge discharge pipe 12. When the cleaning teeth 502 encounter a blocking condition, the shaft-shaped sliding block 503 slides backward in the annular sliding groove 404, and compresses the spring steel sheet 504. However, at this time, the sludge discharge cavity 402 still drives the scraping assembly 6 to rotate forward, and gradually drives the scraping assembly 6 to approach the primary cleaning assembly 5, so that the cleaning needle 602 is inserted into the tooth groove between the cleaning teeth 502, and automatically cleans the cleaning teeth 502.

[0042] The technical scope of the utility model is not limited to the contents in the above description, and those skilled in the art can make various deformations and modifications to the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
