Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage filtering device with high stability. Background Art

[0002] The selection and application of sewage filtration equipment depends on the specific conditions and treatment requirements of the sewage. With the development of science and technology, sewage filtration and treatment equipment is also constantly innovating and upgrading. For example, the innovative process of laser punching machine to make filter mesh has been introduced to improve the filtration efficiency and accuracy. Sewage filtration and treatment equipment is widely used in urban sewage treatment plants, industrial wastewater treatment, rural sewage treatment and wastewater treatment in specific places, such as hospitals and laboratories. The introduction of these equipment not only helps to purify water bodies and maintain water ecological balance, but also provides key support for sustainable development.

[0003] After searching, the patent number "CN220558714U" mentioned in the text that "the utility model discloses a sewage filtering device, including a shell assembly, including a filter chamber, a water inlet opened at the top of the filter chamber, and a water outlet connected to the bottom of the side wall of the filter chamber. The outer wall of the filter chamber is provided with a through hole, and a fixed plate is symmetrically fixed on the outer wall of the through hole; the filter assembly includes a driven roller rotatably mounted on the inner wall of the filter chamber, an active roller rotatably mounted on the inner wall of the fixed plate, a first motor coaxially connected to the active roller, and a filter hole conveyor belt sleeved on the driven roller and the active roller". When in use, the cleaning assembly, It includes a threaded rod rotatably mounted on the fixed plate, a second motor coaxially connected to the threaded rod, and a guide rod fixed on the fixed plate, which can drive the arc scraper to move and scrape impurities on the surface of the filter hole conveyor belt, so as to further reduce the blockage of the filter hole conveyor belt. However, in the process of filtering sewage, since there is not only one kind of impurity in the sewage, but also fine sand that can be precipitated, large debris, and various micro impurities, when filtering sewage, a single process of filtering sewage is likely to cause incomplete sewage filtration, and various impurities of different sizes are likely to block the filtration system, thereby causing damage to the filtration equipment.

[0004] Therefore, we provide a highly stable sewage filtration equipment to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-stability sewage filtering device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-stability sewage filtering device, comprising a sewage treatment tank and a sewage treatment filtering mechanism, wherein the sewage treatment filtering mechanism is installed inside the sewage treatment tank;

[0007] The sewage treatment filtering mechanism comprises a sewage large particle filtering component, a sediment sedimentation component and a flocculant adding component.

[0011] Preferably, the flocculant adding component includes a flocculant control pump, a flocculant nozzle and a water quality detector. The flocculant control pump is installed on the right side of the sediment sedimentation tank, the flocculant nozzle is installed on the lower side of the flocculant control pump, and water quality detectors are provided on both the front and rear sides of the flocculant nozzle.

[0012] Preferably, a secondary filtering mechanism is installed on the right side of the sewage treatment tank, and the secondary filtering mechanism includes an oily adsorption component and an activated carbon filtering component. An oily adsorption component is installed on the right side of the sewage treatment tank, and an activated carbon filtering component is installed on the right side of the oily adsorption component.

The large-particle filter net can perform primary filtration on larger impurities or various plastic wastes in the sewage at the beginning.

The sewage finally flows into the activated carbon adsorption bin, and then the activated carbon particle core performs the final filtration of trace elements, and can be discharged through the drainage pump. In this way, the trace impurities in the sewage can be finally filtered through the activated carbon particle core, and the odor in the sewage can be absorbed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-4 As shown, the utility model provides a technical solution: a high-stability sewage filtering device, comprising a sewage treatment tank 1 and a sewage treatment filtering mechanism 2, wherein the sewage treatment filtering mechanism 2 is installed inside the sewage treatment tank 1;

[0025] The sewage treatment filtering mechanism 2 includes a sewage large particle filtering component 21, a silt sedimentation component 22 and a flocculant adding component 23. The sewage large particle filtering component 21 is arranged on the upper side of the sewage treatment tank 1, the silt sedimentation component 22 is arranged on the lower side of the sewage treatment tank 1, and the flocculant adding component 23 is arranged on the right side of the sewage large particle filtering component 21.

[0026] Furthermore, the sewage large particle filter assembly 21 includes a rotating shaft 211, a water inlet trough 212, a large particle filter screen 213 and a water inlet 214. The rotating shaft 211 is welded on the left side of the sewage treatment tank 1, and the water inlet trough 212 is welded on the upper side of the rotating shaft 211. The large particle filter screen 213 is installed on the inner side of the water inlet trough 212, and the water inlet 214 is arranged on the lower side of the water inlet trough 212. When it is needed, the water inlet trough 212 is buckled onto the water inlet 214 along the rotating shaft 211. In this way, after the large particle filter screen 213 has filtered to a certain extent, the water inlet trough 212 can be turned sideways by the rotating shaft 211, so that the collected impurities can be dumped to avoid the risk of blockage due to large accumulation of impurities.

[0027] Furthermore, the large particle filter 213 is welded to the water inlet trough 212. The large particle filter 213 is made of a large-mesh metal mesh. When needed, the large particle filter 213 can perform primary filtration on larger impurities or various plastic wastes in the sewage at the beginning. Through multi-stage filtration, the garbage can be classified, providing convenience for subsequent sewage cleaning.

[0028] Furthermore, the sedimentation assembly 22 includes a sedimentation tank 221 and a sand discharge port 222. The sedimentation tank 221 is welded to the lower side of the sewage treatment tank 1, and the left side of the sedimentation tank 221 is threadedly connected with the sand discharge port 222. When it is needed, as the sediment and impurities adsorbed by the flocculant are naturally precipitated into the sedimentation tank 221, such fine impurities can be discharged through the sand discharge port 222 to avoid impurity accumulation.

[0029] Furthermore, the flocculant adding component 23 includes a flocculant control pump 231, a flocculant nozzle 232 and a water quality detector 233. The flocculant control pump 231 is installed on the right side of the sediment sedimentation tank 221, and the flocculant nozzle 232 is installed on the lower side of the flocculant control pump 231. Water quality detectors 233 are arranged on both the front and rear sides of the flocculant nozzle 232. When needed, the flocculant control pump 231 will discharge the flocculant into the sewage treatment tank 1 through the flocculant nozzle 232, so that the trace impurities in the water can be converted into visible and precipitable flocs through adsorption, thereby facilitating the precipitation and discharge of such impurities, and the water quality detector 233 will monitor the impurity content in the sewage in real time.

[0030] Embodiment 2

[0031] See also Figure 1-4 As shown, in contrast to Example 1, as another embodiment of the utility model, a secondary filtering mechanism 3 is installed on the right side of the sewage treatment tank 1, and the secondary filtering mechanism 3 includes an oily adsorption component 31 and an activated carbon filter component 32. The right side of the sewage treatment tank 1 is installed with an oily adsorption component 31, and the right side of the oily adsorption component 31 is installed with an activated carbon filter component 32. The oily adsorption component 31 includes a pump compartment 311, a water pump 312, an oily adsorption tank 313 and an oily adsorption membrane 314. The pump compartment 311 is welded on the right side of the sewage treatment tank 1, and the pump compartment 312 is welded on the right side of the sewage treatment tank 1. A water pump 312 is installed on the inner side of the bin 311, and an oily adsorption tank 313 is welded to the right side of the water pump 312. An oily adsorption membrane 314 is provided on the inner side of the oily adsorption tank 313. When needed, the oily adsorption membrane 314 will adsorb the oily substances in the water. Since the oily substances in the sewage cannot be discharged through natural sedimentation, and the flocculant cannot completely coagulate the oily substances, the oily adsorption membrane 314 is used for thorough filtration to prevent the oil film in the sewage from flowing out and damaging the water source again.

[0032] Furthermore, the activated carbon filter assembly 32 includes an activated carbon adsorption bin 321, an activated carbon particle core 322 and a drainage pump 323. The activated carbon adsorption bin 321 is welded to the lower side of the oily adsorption tank 313, the activated carbon particle core 322 is installed on the inner side of the activated carbon adsorption bin 321, and the drainage pump 323 is installed on the lower side of the activated carbon particle core 322. When it is needed, the sewage finally flows into the activated carbon adsorption bin 321, and then the activated carbon particle core 322 performs the final filtration of trace elements, and then it can be discharged through the drainage pump 323. In this way, the trace impurities in the sewage can be finally filtered through the activated carbon particle core 322, and the odor in the sewage can be absorbed.

[0033] Working principle: A high-stability sewage filtration device is moved to the working position. When in use, the first step is to buckle the water inlet 212 on the sewage treatment tank 1 along the rotating shaft 211 to the water inlet 214, and then pour the sewage along the water inlet 212. As the sewage is poured in, the large particle filter 213 will perform the first filtration. In the second step, after the sewage enters the sewage treatment tank 1, the flocculant control pump 231 will spray the flocculant into the sewage treatment tank 1 through the flocculant nozzle 232, and the water quality detector 233 will monitor the water quality in real time. After settling in the sedimentation tank 221, the water quality is improved. The water pump 312 in the pump chamber 311 will pump the precipitated sewage into the oil adsorption tank 313, and the oil in the sewage will be adsorbed through the oil adsorption membrane 314. In the third step, the sewage flows into the activated carbon particle core 322 in the activated carbon adsorption chamber 321 again, and then the filtered sewage is discharged from the drainage pump 323, and the precipitated impurities are discharged from the sedimentation tank 221 by opening the sand discharge port 222, thus completing the use process of a highly stable sewage filtration equipment.
