Description

Technical Field

[0001] The present invention relates to the field of sewage treatment equipment, and in particular to sewage treatment equipment and method. Background Art

[0002] Among the water pollution caused by human production activities, water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and has complex components. It is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants discharged by industry. The pollutants contained in industrial wastewater vary greatly depending on the type of factory. Even for the same type of factory, the quality and quantity of pollutants contained are different due to different production processes. In addition to the direct injection of industrial wastewater into the water body to cause pollution, solid waste and waste gas will also pollute the water body. Therefore, it is necessary to use sewage treatment equipment to filter the sewage before discharging it, thereby reducing environmental pollution.

[0003] The utility model patent with application number CN202321535872.9 discloses a sewage treatment and filtering device, including a frame, the back side of which is provided with slots equidistantly spaced apart, and the internal buckles of the slots are connected to a filter screen, thereby solving the problem of impurities and pollutants generated during the filtration process, which easily cause blockage and affect the filtration efficiency of sewage.

[0004] However, during its use, the filtered impurities and pollutants cannot be cleaned up in time, which will still cause blockage and affect the efficiency of sewage filtration. In the process of filtration, sewage is exposed to the air and will pollute the surrounding environment, especially in summer. Sewage is prone to emit unpleasant gases under the sun, and there is also an aeration process in the sewage treatment process. During aeration, the diffusion of unpleasant gases in the sewage will be further accelerated, polluting the air. Summary of the invention

[0017] A method for using a sewage treatment device comprises the following steps:

[0023] (III) Beneficial effects

[0024] The present invention provides a sewage treatment device and method, which has the following beneficial effects:

[0025] 1. When the filtering equipment is working, the impurities will be automatically collected into the collection barrel through the cooperation of the collection filter plate, the collection slot and the sponge pad on the outside of the sealing conveyor belt. The impurities will not stay on the surface of the filter device, so that the filtering efficiency and the filtering effect can be maintained at a high level.

[0026] 2. Bubbles are injected into the sewage inside the treatment box through aeration equipment, which improves the filtering and removal effect of fine impurities inside the sewage. Centrifugal force is used as the driving force, and during the process of injecting bubbles, the bubbles emerging from the sewage will not diffuse into the outside air, thereby reducing air pollution.

[0027] 3. The collecting filter plate and the collecting groove are retracted into the middle of the collecting barrel and then protrude into the inside of the collecting barrel. The protruding surfaces of the collecting filter plate and the collecting groove are rinsed by the water inside the collecting barrel to prevent clogging. After each impurity collection, the collecting groove extends outward and contacts with the sponge pad, which is wiped and cleaned by the sponge pad to further prevent clogging and improve the effect of cleaning impurities inside the sewage.

[0028] 4. The inside of the equipment can be flushed and cleaned by injecting cleaning liquid through the sewage injection pipe. At the same time, the impurities filtered out from the inside can be pumped out through the sewage pipe. After the internal impurities are cleaned, water is injected into the inside through the sewage pipe to achieve the purpose of reverse flushing, which improves the effect of cleaning the inside. The cleaning operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Specifically, the impurities in the sewage outside the collection barrel 81 are continuously filtered by the filtering device 8 and collected into the collection barrel 81 for storage, and during the collection process, the surfaces of the collection filter plate 93 and the collection slot 94 are continuously cleaned and wiped to prevent blockage from affecting subsequent collection work.

[0046] In this embodiment, the inner gear disc 67 meshes with the inner rotating gear disc 73 , the inner rotating gear disc 73 meshes with the outer rotating gear disc 74 , and the outer rotating gear disc 74 meshes with the meshing gear ring 75 .

[0047] Specifically, when 97 rotates, it drives the inner rotating gear plate 73 to engage, and the inner rotating gear plate 73 drives the outer rotating gear plate 74 to rotate. When the inner rotating gear plate 73 rotates, it rolls along the inner side of the meshing gear ring 75 under the support of the outer support rod 71 and the mounting inclined seat plate 72, thereby driving the rotating sleeve 66 to rotate through the outer support rod 71.

[0048] In this embodiment, the collecting filter plate 93 is made of spring steel and is arc-shaped.

[0049] Specifically, the collecting filter plate 93 can be deformed and retracted into the collecting barrel 81. The arc-shaped design enables the collecting filter plate 93 to extend and rotate to push the impurities in the sewage inward for collection.

[0050] In this embodiment, a sponge pad is sleeved on the outer side of the sealing conveyor belt 88 , and the sponge pad is in contact with the surface of the collecting filter plate 93 .

[0051] Specifically, when the filtering device 8 is working, the impurities are automatically collected into the collection barrel 81 through the cooperation of the collecting filter plate 93, the collecting groove 94 and the sponge pad on the outside of the sealing conveyor belt 88, and the impurities will not remain on the surface of the filtering device, thereby maintaining a high filtering efficiency and a high filtering effect.

[0055] Specifically, the one-way valve is used to prevent sewage from flowing back into the stirring exhaust pipe 62, and when the stirring exhaust pipe 62 rotates, the gas inside will be discharged outward due to centrifugal force.

[0056] A method for using a sewage treatment device comprises the following steps:

[0057] Step 1: Add sewage into the treatment box 1 through the sewage injection pipe 3, and make the sewage water level be located near the middle of the highest collecting filter plate 93. A fine filter cover is installed on the inner side of the highest collecting filter plate 93 to facilitate filtering fine impurities through the fine filter cover;

[0058] Step 2: Start the power motor 5, and drive the power drive shaft 51 to rotate through the power motor 5, and the power drive shaft 51 drives the inner gear plate 67 to rotate, and the inner gear plate 67 drives the outer power device 7 to rotate, and at the same time, the power device 7 drives the filter device 8 below it to rotate, and the filter device 8 rotates to clean the impurities in the sewage outside it, and collects the filtered impurities in the collection bucket 81;

[0059] Step 3: When the inner gear disc 67 rotates, it also drives the vertical pipe 61 to rotate. The vertical pipe 61 rotates to discharge gas into the sewage inside the treatment box 1, and tiny impurities in the sewage float upward through bubbles, thereby improving the effect of purifying, filtering and removing impurities inside the sewage;

[0060] Step 4: During the aeration and filtration process, the generated gas will circulate inside the treatment box 1 and the sealing cover 64, and the activated carbon inside the sealing cover 64 will also adsorb and deodorize the gas flowing through, completing the gas circulation inside, so that the unpleasant odor in the sewage treatment process will not be emitted to the outside;

[0061] Step 5: After the filtration is completed, open the drain pipe 4 to discharge the filtered sewage inside the treatment box 1, and the water inside the collection barrel 81 is discharged outward through the fine filter holes and finally discharged through the drain pipe 4. When it is necessary to clean the inside of the treatment box 1, inject cleaning liquid into the treatment box 1 through the sewage injection pipe 3, and the power motor 5 drives the power drive shaft 51 to rotate to make the internal equipment run for stirring and rotation cleaning. At the same time, the cleaning water entering the collection barrel 81 is extracted along the suction pipe 82 and the sewage flow cavity 84 through the sewage pipe 85. At the same time, the impurities stored in the collection barrel 81 are extracted together by the cleaning liquid, thereby cleaning the impurities inside the collection barrel 81, and then open the drain pipe 4 to discharge the remaining cleaning liquid inside the treatment box 1 to complete the cleaning work.

[0062] The working principle and use process of the present invention are as follows: first, the sewage to be filtered and purified is discharged into the interior of the treatment box 1 through the sewage injection pipe 3, and the water level of the sewage added to the interior of the treatment box 1 is controlled to be located at the middle of the highest collection filter plate 93, and then the power motor 5 is started, and the power motor 5 drives the power drive shaft 51 to rotate, and the power drive shaft 51 drives the inner gear disc 67 to rotate, and the inner gear disc 67 drives the inner rotating gear disc 73 to rotate, and the inner rotating gear disc 73 drives the outer rotating gear disc 74 to rotate, and the outer rotating gear disc 74 rotates along the inner side of the meshing gear ring 75 when rotating, and the outer rotating gear disc 74 drives the collection bucket 81 below it to rotate and revolve synchronously when rolling. The collecting barrel 81 below rotates in the opposite direction, and the collecting barrel 81 drives the collecting filter plate 93 to rotate. When the collecting filter plate 93 rotates, it rotates and stirs the water outside the collecting barrel 81. At the same time, the impurities in the water are filtered out and collected in the collecting groove 94 near the position of the sponge pad outside the sealing conveyor belt 88 through the cooperation of the collecting filter plate 93 and the collecting slot 94. The two collecting barrels 81 drive the collecting filter plates 93 on their respective outer sides to approach each other at the outer ends. When the ends of the collecting filter plates 93 on the outer sides of the two collecting barrels 81 touch, the collecting barrels 81 continue to rotate to squeeze the collecting filter plates 93, so that the collecting filter plates 93 are deformed and pressed against the outer surface of the sealing conveyor belt 88. At the same time, the ends of the collecting filter plates 93 are pushed into the inner connecting seat after being subjected to pressure. 92 drives the inner slide seat 90 to compress the support spring 91, so that the inner slide seat 90 slides along the inner slide groove 89, so that the collecting filter plate 93 shrinks and moves along the collecting notch 86 to the inside of the collecting barrel 81. When the collecting filter plate 93 shrinks and moves, the friction between it and the sponge pad on the outside of the sealing conveyor belt 88 drives the sealing conveyor belt 88 to rotate. When the collecting notches 86 on the outside of the two collecting barrels 81 rotate to the opposite position, the collecting filter plate 93 is pressed into the deepest position, and the impurities filtered in the collecting groove 94 are also brought into the collecting barrel 81 as the collecting filter plate 93 shrinks into the inside of the collecting barrel 81. After the collecting filter plate 93 shrinks into the collecting barrel 81, it continues to rotate under the drive of the collecting barrel 81. At this time, the collecting filter The middle part of the plate 93 is tilted toward the inside of the collection barrel 81 under the support of the edge of the collecting notch 86 near the inner slide groove 89, and the collecting filter plate 93 and the inner side of the collecting slot 94 are washed by the water flow inside the collecting barrel 81, so that the filtered impurities are cleaned, and then the collecting barrel 81 drives the collecting filter plate 93 to continue to rotate, and the distance between the two mutually squeezed collecting filter plates 93 gradually increases, and the pressure on the collecting filter plate 93 decreases, so that the inner slide seat 90 is pushed by the support of the support spring 91 to drive the inner connecting seat 92 and the collecting filter plate 93 to extend outward again. During the process of the collecting filter plate 93 extending outward, the positioning support shaft 87 will not rotate under the action of the one-way bearing, and the sealing conveyor belt 88 and the sponge pad on its outer side remain stationary.During the process of the collecting filter plate 93 extending outward, it rubs against the surface of the sponge pad, and the impurities on the surface of the collecting filter plate 93 that have not been washed are wiped by the sponge pad, so that the impurities can stay inside the collecting barrel 81, so that the holes inside the collecting slots 94 will not be blocked, and after extending, it can achieve efficient filtering and collection effects. The outer rotating toothed disc 74 rolls along the inside of the meshing toothed ring 75 while driving the installation inclined seat plate 72 to revolve. The installation inclined seat plate 72 drives the rotating sleeve 66 to rotate through the outer support rod 71, and the rotating sleeve 66 drives the installation top plate 52 to rotate, and the installation top plate 52 drives the installation The vertical pipe 61 revolves, and the installation of the vertical pipe 61 drives the limit gear 68 to revolve. The limit gear 68 revolves while the inner gear plate 67 rotates, so that the limit gear 68 rotates at a high speed. The limit gear 68 drives the installation of the vertical pipe 61 to rotate. The installation of the vertical pipe 61 drives the stirring exhaust pipe 62 to rotate. The stirring exhaust pipe 62 rotates to assist in stirring the sewage. At the same time, the gas inside the stirring exhaust pipe 62 is discharged outward under the action of centrifugal force. Bubbles are discharged into the sewage. In the process of the bubbles floating upward in the water body, the fine impurities in the water body are adsorbed and driven to the water surface. When When it is necessary to increase the efficiency of discharging bubbles into the sewage, the booster air pump 65 can be started for auxiliary pressurization. The inner wall of the collection filter plate 93 and the collection slot 94 at the highest point is installed with a fine filter cover. The impurities floating on the water surface are filtered by the cooperation of the highest collection filter plate 93, the collection slot 94 and the fine filter cover, and finally collected in the collection barrel 81. In the process of removing impurities from the sewage, the gas completes the internal circulation inside the equipment, and will not diffuse and discharge the gas outward, thereby preventing air pollution. After the filtering process is completed, the drainage pipe 4 is controlled to open to discharge the internal filtered sewage for In subsequent processing, when it is necessary to clean the inside of the treatment box 1, the cleaning liquid is injected into the treatment box 1 through the sewage injection pipe 3, and the power motor 5 drives the power drive shaft 51 to rotate to make the internal equipment run for stirring and self-rotating cleaning. At the same time, the cleaning water entering the collection barrel 81 is pumped out along the suction pipe 82 and the sewage flow cavity 84 through the sewage pipe 85. At the same time, the impurities stored in the collection barrel 81 are driven by the cleaning liquid to be pumped out together, thereby cleaning the impurities inside the collection barrel 81, and then the drainage pipe 4 is opened to discharge the remaining cleaning liquid in the treatment box 1 to complete the cleaning work.
