Description

Technical Field

[0001] The utility model relates to the field of sewage discharge, in particular to a sewage tank with good protection. Background Art

[0002] With the increasing shortage of water resources, sewage treatment, purification and reuse are becoming more and more important for economic and social development. At present, there are many types of sewage treatment equipment used in the field of wastewater treatment. Sewage tank is one of the sewage treatment equipment commonly used for sewage treatment.

[0003] At present, there are many types of sewage tanks, including vehicle-mounted sewage tanks, horizontal water tower sewage tanks, etc., including sewage tanks with sewage sedimentation. Most of the sewage tanks for sewage sedimentation are funnel-type sewage tanks and straight barrel-type sewage tanks. The straight barrel-type sewage tank has a larger diameter, which is more difficult to construct and has a flat bottom, so the sludge is easy to compact into mud at the bottom of the tank; the bottom of the funnel-type sewage tank is designed as a funnel, which makes it difficult for the sludge to compact at the bottom, so that when cleaning the bottom sludge, the time required for workers to break the mud is reduced, thereby more effectively cleaning the sludge at the bottom of the sewage tank.

[0004] However, the above-mentioned funnel-type sewage tank still has certain shortcomings, because it needs to treat the sludge water for a long time, so that a lot of sludge accumulates at the bottom. When cleaning the sludge at the bottom, the bottom mud outlet needs to be opened to discharge the sludge, but some sludge still remains on the inner wall, so workers have to hold a scraper for secondary cleaning, which reduces work efficiency. Therefore, it is urgently needed to improve the existing funnel-type sewage tank. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a sewage tank with good protection to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage tank with good protective performance, comprising a sewage tank body, the sewage tank body is equipped with a water inlet pipe, and a mud guard assembly is arranged on the outer wall of the water inlet pipe, a circular ring 1 is rotatably installed on the bottom of the sewage tank body, and a circular ring 2 is rotatably installed on the end of the sewage tank body, and a scraper connected to the outer wall of the circular ring 2 is fixedly installed on the outer wall of the circular ring 1, the scraper is attached to the inner wall of the bottom of the sewage tank body, and a groove is provided on the outer wall of the scraper, and teeth are provided on the outer wall of the circular ring 1, a bevel gear 1 meshing with the teeth on the circular ring 1 is rotatably installed on the outer wall of the circular ring 1, and a motor for driving the bevel gear 1 is fixedly installed on the outer wall of the sewage tank body, and a support rod for supporting the circular ring 1 is slidably installed on the end of the water inlet pipe, and a mud outlet is provided at the bottom of the sewage tank body.

[0007] By adopting the above technical scheme, under the action of the first and second rings and the scraper, the sewage tank body can be better cleaned, and the probability of residual sludge in the sewage tank body is reduced, thereby improving the efficiency of sludge cleaning, so that the bottom sludge can be cleaned from the inner wall of the sewage tank, and under the action of the scraper and the groove, the sludge is gradually moved toward the mud outlet until it is discharged while being scraped, thereby improving the efficiency of sewage tank cleaning and reducing the time and labor required for workers to clean.

[0008] The utility model is further configured that three support rods are installed at equal angles at the end of the water inlet pipe.

[0009] By adopting the above technical solution, under the effect of the number of support rods, the probability of shaking of ring 1 is reduced when it rotates, so that when the scraper is scraping mud on the inner wall of the sewage tank body, the operation of ring 1, ring 2 and the scraper is more stable and smooth.

[0010] The utility model is further configured such that the first and second circular rings do not directly contact the sewage tank body, and the outer wall edge of the scraper is designed as an inclined surface attached to the inner wall of the sewage tank body.

[0011] By adopting the above technical solution, when the scraper blade slides on the inner wall of the sewage tank, the inclined surface design allows the scraper blade to fit more closely to the inner wall of the sewage tank body when scraping the mud on the inner wall of the sewage tank body, thereby making the sludge in the sewage tank body cleaned more cleanly and reducing the accumulation of residual sludge.

[0012] The utility model is further configured that the notches are staggered in design, and the edges of the notches are inclined in design.

[0013] By adopting the above technical solution, during the process of the scraper blade scraping the sludge, through the setting of the groove, the sludge on the inner wall of the sewage tank body can reduce the resistance of the scraper blade and guide the sludge to slide toward the mud outlet, so that the sludge can be scraped out smoothly.

[0014] The utility model is further configured as follows: a dredging device is installed at the bottom of the water inlet pipe, and the dredging device consists of bevel gear 2, a rotating rod and stirring blades, the end of the motor located in the bottom of the water inlet pipe is installed with bevel gear 1, and bevel gear 2 meshingly connected with bevel gear 1 is installed in the bottom of the water inlet pipe, and a rotating rod is installed at the bottom of bevel gear 2, and stirring blades for dredging the mud outlet are installed at the bottom of the rotating rod.

[0015] By adopting the above technical solution, when the scraper plate cleans the inner wall at the bottom of the sewage tank body, the sludge is discharged through the mud outlet. In the process of discharging the sludge, there is a probability that the mud outlet is blocked. Under the action of the dredging device, while the scraper plate scrapes the inner wall of the sewage tank body, it drives the dredging device to dredge the mud outlet, thereby reducing the probability of the mud outlet being blocked by sludge.

[0016] The utility model is further configured that the rotating rod is located at the center of the mud outlet, and the outer diameter of the stirring blade is smaller than the inner diameter of the mud outlet.

[0017] By adopting the above technical solution and setting the position of the rotating rod, the rotating rod drives the stirring blades to clear the mud outlet, so that the mud outlet is cleared from the center, which reduces the time spent on cleaning the sludge in the sewage tank body.

[0018] The utility model is further configured that four stirring blades are installed at equal angles on the rotating rod, and the stirring blades are all inclined in design.

[0019] By adopting the above technical solution, when the rotating rod rotates, the stirring blades can fully clear the mud outlet, so that when the mud outlet is discharging sludge, it is not easy for the sludge in the sewage tank body to be blocked, reducing the probability of workers having to clean it twice, and making the sewage tank body more convenient to use.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] The utility model is provided with a first circular ring, a second circular ring and a scraper plate. Under the action of the first circular ring, the second circular ring and the scraper plate, the sewage tank body can be cleaned better, the probability of residual sludge in the sewage tank body is reduced, thereby improving the efficiency of sludge cleaning, and the bottom sludge can be cleaned off the inner wall of the sewage tank. Moreover, under the action of the scraper plate and the notch, the sludge is gradually moved toward the mud outlet until it is discharged while being scraped, thereby improving the efficiency of sewage tank cleaning and reducing the time and labor required for workers to clean.

DETAILED DESCRIPTION

[0030] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] Embodiment 1

[0033] A well-protected sewage tank, such as Figure 1 - Figure 5 As shown, it includes a sewage tank body 1.

[0034] Specifically, the sewage tank body 1 is equipped with an inlet pipe 101. When sewage is injected into the sewage tank body 1, the sewage is discharged at a lower position of the sewage tank body 1 through the inlet pipe 101, so that the sludge in the sewage is better precipitated. When the sewage enters the inlet pipe 101, since drugs such as flocculants are added to the sewage, the sludge in the sewage is coagulated, so that the sludge is precipitated. An inclined partition 14 is installed in the inlet pipe 101, so that when the sewage enters the sewage tank body 1 through the inlet pipe 101, it will collide with the partition 14 inside the inlet pipe 101, so that the sewage and the internal drugs are fully integrated, and the effect of the drugs is maximized, so that when the sewage is precipitated, the sludge sinks more stably, thereby The water quality gradually becomes clear, thereby achieving the effect of purifying the water source, and a mud retaining assembly is arranged on the outer wall of the water inlet pipe 101. When sewage mixed with sludge enters the sewage tank body 1, due to the impact generated by the injection of water flow, the sludge has the probability of floating upward along the impact of the water flow, thereby causing the sludge to cause secondary pollution to the clean water filtered on the upper layer, and under the action of the mud retaining assembly, the upward floating tendency of the sludge is blocked by the mud retaining plate 13, so that the sludge cannot float upward, so that the clean water on the upper layer is not polluted for the second time. A circular ring 1 2 is rotatably installed on the inner wall of the bottom of the sewage tank body 1, and a circular ring 2 3 is rotatably installed on the end of the sewage tank body 1, and a scraper plate 4 connected to the outer wall of the circular ring 2 3 is fixedly installed on the outer wall of the circular ring 1 2. When the circular ring 1 2 and the circular ring 2 3 rotate , driving the scraper plate 4 to slide on the inner wall of the sewage tank body 1, so that the scraper plate 4 obtains the sliding force, and the scraper plate 4 is attached to the inner wall of the bottom of the sewage tank body 1. When the scraper plate 4 slides, the sludge adhering to the inner wall of the sewage tank body 1 is cleaned, so that the residual sludge on the inner wall of the sewage tank body 1 is reduced, thereby reducing the probability of the residual sludge gradually stacking to form stubborn mud. The outer wall of the scraper plate 4 is provided with a slot 5. When the scraper plate 4 scrapes and cleans the inner wall of the sewage tank body 1, the setting of the slot 5 reduces the resistance of the scraper plate 4 to the scraper plate 4 when the scraper plate 4 slides, so that the scraper plate 4 is smoother during operation, and the probability of jamming and damage is reduced. The outer wall of the ring 2 is provided with teeth, and the outer wall of the ring 2 is rotated to A bevel gear 6 meshing with the teeth on the circular ring 2 is installed. When the bevel gear 6 rotates, the circular ring 2 is driven to rotate synchronously, so that the circular ring 2 obtains the rotation force, and a motor 7 for driving the bevel gear 6 is fixedly installed on the outer wall of the sewage tank body 1. Under the action of the motor 7, the bevel gear 6 is driven to rotate, so that the bevel gear 6 obtains the rotation force, so that when rotating, under the action of the gear transmission, the bevel gear 6 rotates to drive the circular ring 2 to rotate, so that the circular ring 2 synchronously drives the scraper 4 and the circular ring 2 3 to rotate, thereby realizing the sludge cleaning of the inner wall of the sewage tank body 1, and a support rod 201 for supporting the circular ring 2 is slidably installed at the end of the water inlet pipe 101. Through the setting of the support rod 201,The support rod 201 supports the ring 1 2, the ring 2 3 and the scraper 4 inside the sewage tank body 1. When the bevel gear 1 6 drives the ring 1 2 to rotate, it simultaneously drives the support rod 201 to rotate on the outer wall of the end of the water inlet pipe 101, so that the support rod 201 obtains the rotation force. In addition, a mud outlet 8 is provided at the bottom of the sewage tank body 1. When cleaning the mud in the sewage tank body 1, the mud passes through the mud outlet 8, thereby discharging the mud in the sewage tank body 1.

[0035] See also Figure 1 - Figure 5 Three support rods 201 are installed at equal angles at the end of the water inlet pipe 101. Due to the number of support rods 201, the probability of shaking of the ring 1 2 is reduced when it rotates, so that when the scraper 4 scrapes the mud on the inner wall of the sewage tank body 1, the ring 1 2, the ring 2 3 and the scraper 4 can operate more steadily and smoothly.

[0036] See also Figure 1 - Figure 5 , the ring 1 2 and the ring 2 3 do not directly contact the sewage tank body 1. When the sewage tank body 1 is cleaned, the probability of the sludge falling into the gap between the ring 2 3 and the sewage tank body 1 is reduced, so that the ring 1 2, the ring 2 3 and the scraper 4 can clean the inner wall of the sewage tank body 1 more smoothly, reducing the probability of jamming.

[0037] See also Figure 1 - Figure 5 The outer wall edge of the scraper blade 4 is designed as a sloped surface attached to the inner wall of the sewage tank body 1. When the scraper blade 4 slides on the inner wall of the sewage tank, the sloped surface design allows the scraper blade 4 to be closer to the inner wall of the sewage tank body 1 when scraping the mud on the inner wall of the sewage tank body 1, thereby making the sludge in the sewage tank body 1 clean more thoroughly and reducing the accumulation of residual sludge.

[0038] See also Figure 1 - Figure 5 The notches 5 are staggered in design. When the scraper 4 is scraping mud, the notches 5 are set so that the mud on the inner wall of the sewage tank body 1 can reduce the resistance of the scraper 4 and guide the mud to slide toward the mud outlet 8 under the action of the notches 5, so that the mud can be scraped out smoothly. The edge of the notches 5 is designed as a slope. Under the guidance of the slope, the scraper 4 can better clean the mud along the notches 5 when cleaning the inner wall of the sewage tank body 1.

[0039] Embodiment 2

[0040] See also Figure 6 - Figure 7The difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, a dredging device 9 is installed at the bottom of the water inlet pipe 101. When the scraper blade 4 cleans the inner wall of the bottom of the sewage tank body 1, the sludge is discharged through the mud outlet 8. In the process of discharging the sludge, there is a probability that the mud outlet 8 is blocked. Under the action of the dredging device 9, while the scraper blade 4 scrapes the mud on the inner wall of the sewage tank body 1, it drives the dredging device 9 to dredge the mud outlet 8, thereby reducing the probability of the mud outlet 8 being blocked by sludge. The dredging device 9 is composed of a bevel gear 10, a rotating rod 11 and a stirring blade 12. The end of the motor 7 located at the bottom of the water inlet pipe 101 is installed with a bevel gear 6. When the motor 7 is running, it drives the bevel gear 6 at the bottom of the water inlet pipe 101 to rotate, so that the bevel gear 6 obtains the rotation force, and the water inlet pipe 1 A bevel gear 2 10 meshing with the bevel gear 1 6 is installed at the bottom of 01. Through the characteristics of gear transmission, when the bevel gear 1 6 rotates, it drives the bevel gear 2 10 to rotate synchronously, so that the bevel gear 2 10 obtains the rotation force, and a rotating rod 11 is installed at the bottom of the bevel gear 2 10. When the bevel gear 1 6 drives the bevel gear 2 10 to rotate synchronously, the bevel gear 2 10 drives the rotating rod 11 to rotate, so that the rotating rod 11 obtains the rotation force, and a stirring blade 12 for unblocking the mud outlet 8 is installed at the bottom of the rotating rod 11. When the rotating rod 11 rotates, it drives the stirring blade 12 at the bottom, so that the stirring blade 12 obtains the rotation force, so that when the stirring blade 12 rotates synchronously with the rotating rod 11, the sludge in the mud outlet 8 is unblocked, thereby reducing the probability of blockage of the mud outlet 8.

[0041] See also Figure 6 - Figure 7 The rotating rod 11 is located at the center of the mud outlet 8. By setting the position of the rotating rod 11, the rotating rod 11 drives the stirring blade 12 to dredge the mud outlet 8, so that the mud outlet 8 is dredged from the center, so that the sludge in the sewage tank body 1 is cleaned, and the cleaning time is reduced, and the rotating outer diameter of the stirring blade 12 is smaller than the inner diameter of the mud outlet 8.

[0042] See also Figure 6 - Figure 7 Four stirring blades 12 are installed at equal angles on the rotating rod 11, so that when the rotating rod 11 rotates, the stirring blades 12 can fully clear the mud outlet 8, so that when the mud outlet 8 is discharged, it is not easy to cause the sludge in the sewage tank body to be blocked, reducing the probability of workers cleaning it twice, making the sewage tank body 1 more convenient to use, and the stirring blades 12 are all inclined.

[0043] The working principle of the utility model is as follows: when in use, sewage enters the sewage tank body 1 through the water inlet pipe 101. Due to the high water flow rate, the sewage enters the water inlet pipe 101 and collides with the partition 14, thereby generating an impact force, so that the sewage and the medicine in the sewage are fully integrated, and then flows out of the water inlet pipe 101. When the sewage flows out of the water inlet pipe 101, there is a probability that the sludge will float upward under the action of the impact force, causing secondary pollution of the clean water. Under the action of the mud guard 13, most of the rising sludge can be intercepted, so that the sludge is blocked. When the sewage tank body 1 is internally cleaned, the motor 7 is turned on, so that the bevel gear 6 starts to drive the ring 2 to rotate through the gear transmission, so that the scraper 4 scrapes the sludge on the inner wall of the bottom of the sewage tank body 1. When the bevel gear 6 rotates, the rotating rod 11 rotates synchronously, thereby driving the stirring blade 12 to dredge the mud outlet 8, thereby increasing the cleaning efficiency, reducing the labor and time required for workers to clean, and improving the overall working efficiency of the sewage tank.
