Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a multi-stage sewage treatment equipment. Background Technology
[0002] Multi-stage wastewater treatment equipment is a system that purifies wastewater step by step through segmented treatment processes (such as a combination of physical, biological, and chemical methods). Its core objective is to efficiently remove pollutants such as COD, BOD, nitrogen, and phosphorus, adapting to different water quality requirements. It is commonly used to treat domestic and industrial wastewater.
[0003] In existing multi-stage wastewater treatment equipment, wastewater is transported into the machine through the inlet pipe. The wastewater then preferentially enters the physical chamber, where multi-stage filters intercept and filter out impurities and debris. It then flows into the biological chamber, where microorganisms degrade pollutants through metabolism. Finally, it flows into the chemical chamber, where oxidants and other chemical agents degrade and disinfect the recalcitrant organic matter in the wastewater, achieving multi-stage treatment of the wastewater. The treated wastewater is then discharged through the outlet pipe for use.
[0004] However, because wastewater contains a variety of pollutants, these pollutants may accumulate inside the body after being filtered and degraded, resulting in excessive accumulation of pollutants inside the body, which can affect the normal operation of the body and the effectiveness of wastewater filtration. Utility Model Content
[0005] The technical problem this invention aims to solve is that wastewater contains various pollutants, which may cause these pollutants to accumulate inside the machine after filtration and degradation, resulting in excessive accumulation of pollutants inside the machine and affecting its normal operation and wastewater filtration effect.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a multi-stage sewage treatment equipment, comprising: a body, which is buried in the ground or placed on the ground to carry and treat sewage, wherein the sewage is transported through an inlet pipe to multiple treatment chambers inside the body for purification, and then discharged through an outlet pipe for use; and a sludge removal device, which is installed in multiple treatment chambers inside the body, wherein the sludge removal device is located at the bottom of the body to collect and discharge the sediment inside the treatment chambers.
[0007] Preferably, the decontamination device includes: a collection box, which is fixed inside the machine body to collect sediment, and an auxiliary device is provided on one side of the collection box; a winding rod, which is fixedly installed on the collection box by a motor, and the winding rod is connected to the output end of the motor by a coupling; a rectangular plate, which slides inside the collection box, and a spring is fixed between the rectangular plate and the inner wall of the collection box, and a rope is fixed between the rectangular plate and the winding rod; and a pipe, which is fixed to the collection box, and the end of the pipe away from the machine body is connected to a delivery pipe and a pump is used to extract the sediment inside the collection box.
[0008] The aforementioned components achieve the following effects: By incorporating a decontamination device, when pollutants accumulate in the wastewater inside the machine, they fall into the collection box for storage. Once a certain amount of pollutants has accumulated, the motor is activated, causing the winding rod to rotate. During rotation, the winding rod winds up the rope, pulling the rectangular plate along the inside of the collection box towards the pipe. As the rectangular plate moves, it pushes the sediment inside the collection box towards the pipe inlet. At this point, the pump is activated, drawing out the sediment from the collection box through the pipe and discharging it through the delivery pipe. This achieves rapid cleaning of sediment inside the machine, reducing the accumulation of pollutants after filtration and degradation, thus minimizing the impact on normal operation and wastewater filtration. It also improves the ease of cleaning sediment from inside the machine.
[0009] Preferably, the decontamination device further includes a guide rod, which is fixed inside the collection box, wherein the guide rod is placed inside the rectangular plate and the spring for limiting its position.
[0010] The effect achieved by the above components is as follows: by setting the guide rod, the guide rod can be placed inside the rectangular plate to limit its movement, thereby reducing the tilting of the rectangular plate during movement and reducing the bending of the spring.
[0011] Preferably, the decontamination device further includes: a guide plate, which is fixed to the collection box, wherein the surface of the guide plate has a slope, and the guide plate is placed in the reset position of the rectangular plate to intercept the sediment and guide it into the collection box through its own slope.
[0012] The effect achieved by the above components is as follows: by setting the guide plate, the upper part of the rectangular plate at the reset position can be covered to intercept the sediment, reduce the sediment from falling into the gap between the rectangular plate near the spring side and the collection box, and affect the rectangular plate's pushing of the sediment.
[0013] Preferably, a shovel is fixedly connected to the side of the rectangular plate near the pipe, wherein the surface of the shovel is triangular and fits against the inner wall of the collection box.
[0014] The effect achieved by the above components is that by setting up shovels, the shovels can move with the rectangular plate and scoop up the sediment adhering to the inner wall of the collection box, thereby improving the scraping effect of the rectangular plate on the sediment.
[0015] Preferably, the auxiliary device includes: an electric telescopic rod fixedly connected to the collection box; and a push plate fixedly connected to the moving end of the electric telescopic rod, wherein the push plate is placed inside the collection box to push the sediment pushed by the rectangular plate to both sides of the collection box.
[0016] The effect achieved by the above-mentioned components is as follows: By setting up an auxiliary device, when the rectangular plate pushes the sediment inside the collection box to a position close to the pipe, two electric telescopic rods are activated, causing the two electric telescopic rods to simultaneously drive the two push plates to move in opposite directions. This causes the two push plates to move towards the edge of the collection box at the same time, so that the two push plates push the sediment pushed by the rectangular plate to both sides of the collection box during the movement, bringing the sediment closer to the inlet of the pipe. This achieves the auxiliary pushing of the sediment, reducing the situation where the sediment is placed in the middle of the collection box, resulting in the inlet of the pipe being far from the sediment in the middle, which affects the sediment extraction effect, and further improving the sediment discharge effect.
[0017] Preferably, the auxiliary device further includes a baffle, wherein the baffle is fixed to the side of the push plate away from the electric telescopic rod.
[0018] The effect achieved by the above components is that by setting up baffles, the baffles can intercept the sediment pushed by the pusher plate, reducing the situation where sediments roll over the surface of the pusher plate during the pushing process, causing some sediments to fail to be pushed.
[0019] Preferably, the auxiliary device further includes a rubber column, wherein the rubber column is fixed to the side of the push plate away from the baffle, separating the two push plates.
[0020] The effect achieved by the above components is that by setting rubber pillars, the rubber pillars can separate the two push plates, reducing the possibility of collision when the two push plates move closer to each other.
[0021] The beneficial effects of this utility model are:
[0022] By installing a decontamination device, the sediment inside the machine can be quickly cleaned, reducing the amount of pollutants that accumulate inside the machine after filtration and degradation, thus preventing excessive pollutant buildup that could affect normal operation and wastewater filtration. This also improves the ease of cleaning sediment inside the machine. Attached Figure Description

[0031] Figure 1-4 The multi-stage wastewater treatment equipment shown includes: a body 1, which is buried in the ground or placed on the ground to carry and treat wastewater, wherein the wastewater is transported through an inlet pipe 2 to multiple treatment chambers inside the body 1 for purification, and then discharged through an outlet pipe 3 for use; and a sludge removal device 4, which is installed in multiple treatment chambers inside the body 1, wherein the sludge removal device 4 is located at the bottom of the body 1 to collect and discharge the sediment inside the treatment chambers.
[0032] Figure 2 and Figure 3The decontamination device 4 shown includes: a collection box 41, which is fixed inside the machine body 1 to collect sediment, and an auxiliary device 5 is provided on one side of the collection box 41; a winding rod 42, which is fixedly mounted on the collection box 41 by a motor, and the winding rod 42 is connected to the output end of the motor by a coupling; a rectangular plate 43, which slides inside the collection box 41, and a spring 44 is fixed between the rectangular plate 43 and the inner wall of the collection box 41, and a rope 45 is fixed between the rectangular plate 43 and the winding rod 42; and a pipe 46, which is fixed to the collection box 41, and the end of the pipe 46 away from the machine body 1 is connected to a delivery pipe and a pump is used to extract the sediment inside the collection box 41. By setting up the decontamination device 4, when sewage pollutants are deposited inside the machine body 1, the deposited pollutants fall into the collection box. The collection box 41 stores pollutants. When a certain amount of pollutants accumulates, the motor is activated, causing the winding rod 42 to rotate. During the rotation, the winding rod 42 winds up the rope 45, pulling the rectangular plate 43 along the inside of the collection box 41 towards the pipe 46. As the rectangular plate 43 moves, it pushes the sediment inside the collection box 41 to a position near the inlet of the pipe 46. At this time, the pump is activated, drawing out the sediment from the collection box 41 through the pipe 46 and discharging it through the delivery pipe. This achieves rapid cleaning of the sediment inside the machine body 1, reducing the accumulation of pollutants inside the machine body 1 after filtration and degradation, thus preventing excessive pollutant accumulation that could affect the normal operation of the machine body 1 and the filtration effect on wastewater. This also improves the convenience of cleaning the sediment inside the machine body 1.
[0033] Figure 2 and Figure 3The decontamination device 4 shown also includes: a guide rod 48, which is fixed inside the collection box 41. The guide rod 48 is positioned inside the rectangular plate 43 and the spring 44 to limit their movement. By setting the guide rod 48, it can be positioned inside the rectangular plate 43 to limit its movement, reducing the tilting of the rectangular plate 43 during movement and reducing the excessive bending of the spring 44. The decontamination device 4 also includes: a guide plate 49, which is fixed to the collection box 41. The surface of the guide plate 49 has a slope. The guide plate 49 is positioned at the reset position of the rectangular plate 43 to intercept and remove sediment. The sediment is guided into the collection box 41 by its own slope. The guide plate 49 can cover the top of the rectangular plate 43 at the reset position to intercept the sediment and reduce the sediment from falling into the gap between the rectangular plate 43 near the spring 44 and the collection box 41, which would affect the rectangular plate 43's pushing of the sediment. A shovel 47 is fixedly connected to the side of the rectangular plate 43 near the pipe 46. The surface of the shovel 47 is triangular and fits against the inner wall of the collection box 41. By setting the shovel 47, it can move with the rectangular plate 43 and scoop up the sediment adhering to the inner wall of the collection box 41, thereby improving the scraping effect of the rectangular plate 43 on the sediment.
[0034] Figure 4 The auxiliary device 5 shown includes: an electric telescopic rod 51, which is fixedly connected to the collection box 41; and a pusher plate 52, which is fixedly connected to the moving end of the electric telescopic rod 51. The pusher plate 52 is placed inside the collection box 41 to push the sediment pushed by the rectangular plate 43 to both sides of the collection box 41. By setting the auxiliary device 5, when the rectangular plate 43 pushes the sediment inside the collection box 41 to a position close to the pipe 46, the two electric telescopic rods 51 are activated, so that the two electric telescopic rods 51 simultaneously drive the two pushers 52 to move in opposite directions, so that the two pushers 52 simultaneously move to a position close to the edge of the collection box 41. During the movement, the two pushers 52 push the sediment pushed by the rectangular plate 43 to both sides of the collection box 41, so that the sediment is closer to the inlet of the pipe 46. This achieves the auxiliary pushing of the sediment, reduces the situation where the sediment is placed in the middle of the collection box 41, resulting in the inlet of the pipe 46 being far from the sediment in the middle, which affects the sediment extraction effect, and further improves the sediment discharge effect.
[0035] Figure 4The auxiliary device 5 shown also includes: a baffle 53, wherein the baffle 53 is fixedly connected to the side of the push plate 52 away from the electric telescopic rod 51. By setting the baffle 53, the baffle 53 can intercept the sediment pushed by the push plate 52, reducing the situation where the sediment rolls over the surface of the push plate 52 during the pushing process, causing some sediment to fail to be pushed. The auxiliary device 5 also includes: a rubber column 54, wherein the rubber column 54 is fixedly connected to the side of the push plate 52 away from the baffle 53, separating the two push plates 52. By setting the rubber column 54, the rubber column 54 can separate the two push plates 52, reducing the situation where the two push plates 52 collide when they move closer to each other.
[0036] Working principle: First, sewage is transported into the body 1 through the inlet pipe 2. Then, the sewage preferentially enters the physical chamber, where multi-stage filters intercept and filter impurities and debris. It then flows into the biological chamber, where microorganisms degrade pollutants through metabolism. Finally, it flows into the chemical chamber, where oxidants and other chemical agents degrade and disinfect the difficult-to-decompose organic matter in the sewage, achieving multi-stage treatment of sewage. Finally, it is discharged for use through the outlet pipe 3.
[0037] When wastewater pollutants accumulate inside the machine body 1, they fall into the collection box 41 for storage. When the pollutants accumulate to a certain amount, the motor is activated, causing the motor to drive the winding rod 42 to rotate. During the rotation, the winding rod 42 winds up the rope 45, causing the rope 45 to pull the rectangular plate 43 along the inside of the collection box 41 towards the pipe 46. As the rectangular plate 43 moves, it pushes the sediment inside the collection box 41 to a position near the inlet of the pipe 46. At this time, two electric extensions are activated. The retracting rod 51 causes the two electric telescopic rods 51 to simultaneously drive the two push plates 52 to move in opposite directions, causing the two push plates 52 to move towards the edge of the collection box 41. During the movement, the two push plates 52 push the sediment pushed by the rectangular plate 43 to both sides of the collection box 41, bringing the sediment closer to the inlet of the pipe 46, thus achieving auxiliary pushing of the sediment. At this time, the pump is started, so that the pump can extract the sediment inside the collection box 41 through the pipe 46 and discharge it through the delivery pipe, thereby achieving rapid cleaning of the sediment inside the machine body 1.
