Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a sewage treatment device. Background Technology

[0002] In industrial production processes such as coal mining, a large amount of wastewater containing suspended solids, silt and other solid impurities is generated. This wastewater must be effectively treated before it is discharged or reused. Filtration is a common and critical physical separation process in wastewater treatment, and filter screens installed in pipes or containers are usually used to intercept solid impurities.

[0003] However, during the continuous filtration process, a large number of impurities will quickly adhere to and accumulate on the surface of the filter screen, resulting in a reduction in the effective filtration area of ​​the filter screen and a decrease in water flow, which seriously affects the efficiency of the entire sewage treatment system. In order to maintain the normal operation of the system, the clogged filter screen must be cleaned regularly.

[0004] Currently, the main shortcomings of existing methods for cleaning filters are that some simple devices require manual periodic shutdowns to disassemble, wash, or replace the filters. This not only interrupts the continuous wastewater treatment process but also consumes a lot of manpower and has low maintenance efficiency. In order to achieve automation, some solutions have designed automatic cleaning mechanisms, but these mechanisms are often complex in structure and require external power sources such as motors to drive the scrapers or backwashing devices. This undoubtedly increases the manufacturing cost, operating energy consumption, and risk of failure of the equipment, resulting in poor economic efficiency and reliability of the overall device.

[0005] Therefore, this utility model proposes a sewage treatment device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a sewage treatment device, which aims to improve the problems of existing sewage treatment devices where the cleaning of the filter screen depends on external power, resulting in complex structure and high operating energy consumption.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a sewage treatment device, comprising: a sewage treatment pipe, a support frame fixedly connected to the sewage treatment pipe, and a filter screen rotatably disposed inside the sewage treatment pipe; and further comprising a cleaning component disposed inside the sewage treatment pipe.

[0008] The cleaning assembly includes a rotating shaft arranged along the length of the sewage treatment pipe, a rotating blade fixedly connected to the rotating shaft, a stainless steel bevel gear one coaxially fixed to one end of the rotating shaft, a stainless steel bevel gear two meshing with the stainless steel bevel gear one, and a connecting shaft.

[0009] One end of the connecting shaft is fixedly connected to the stainless steel bevel gear II, and the other end is fixedly connected to the filter screen, forming a power transmission path that drives the rotating blades through water flow and thus drives the filter screen to rotate.

[0010] Preferably, the wastewater treatment device further includes a collection box, which is detachably connected to the lower part of the wastewater treatment pipe by a connecting plate and fixing bolts, and a sealing strip is provided at the connection between the collection box and the wastewater treatment pipe.

[0011] Preferably, the wastewater treatment device further includes a sealing assembly, which includes a sealing box that houses a stainless steel bevel gear one and a stainless steel bevel gear two, and a fixing block for fixing the sealing box.

[0012] Preferably, both the rotating shaft and the connecting shaft are fitted with a fixing ring, the fixing ring being rotatably inserted through the wall of the sealing box, and a sealing ring is provided between the outer periphery of the fixing ring and the inner wall of the sealing box.

[0013] Preferably, a rubber ring for radially pushing the sealing ring is provided between the inner circumference of the sealing ring and the outer circumference of the fixing ring.

[0014] Preferably, a plurality of rubber positioning rings are provided on the outer peripheral wall of the sealing ring.

[0015] Preferably, the axis of the rotating shaft is perpendicular to the axis of the connecting shaft.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting up a cleaning component that uses the impact force of water flow to drive the rotating blade to rotate, and transmits the power to the filter screen to make it rotate through a bevel gear set and a transmission shaft system, the problems of easy clogging of the filter screen and the cleaning device relying on external power, complex structure and high energy consumption in the prior art are solved. It achieves the technical effect of automatically and continuously cleaning the filter screen without external power, thereby saving energy, improving the degree of automation and wastewater treatment efficiency.

[0018] 2. In this utility model, by setting up a sealed box to house the bevel gear set, and using a sealing assembly consisting of a fixing ring, a sealing ring, and a rubber ring, the problem of the transmission mechanism being directly exposed to sewage and susceptible to corrosion and wear, resulting in a short service life and unstable operation of the device, is solved. This achieves the technical effect of effectively sealing and protecting the core transmission components, preventing water flow and impurities from eroding, thereby significantly improving the operational stability and service life of the device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-6 The present invention provides an embodiment of a sewage treatment device, which aims to solve the problems of easy clogging of the filter screen and the complex structure and high energy consumption of the automatic cleaning mechanism in the prior art sewage treatment devices.

[0029] The wastewater treatment device includes a wastewater treatment pipe 1 and a support frame 2 fixedly connected to and supporting the wastewater treatment pipe 1. A filter screen 3 is rotatably installed inside the wastewater treatment pipe 1. A cleaning assembly 4 for automatically cleaning the filter screen 3 is also installed inside the wastewater treatment pipe 1. The core structure of the cleaning assembly 4 is that it includes a rotating shaft 401 arranged along the length of the wastewater treatment pipe 1, a rotating blade 402 fixedly connected to the rotating shaft 401 and rotating under the impact of water flow, a stainless steel bevel gear 407 coaxially fixed to one end of the rotating shaft 401, and a stainless steel bevel gear 407 meshing with the stainless steel bevel gear 407. 08, and connecting shaft 409; one end of connecting shaft 409 is fixedly connected to stainless steel bevel gear 408, and the other end is fixedly connected to filter screen 3. Through this transmission structure, the kinetic energy of the water flow drives the rotating shaft 401 to rotate via the rotating blade 402, and transmits the motion to the connecting shaft 409 through the meshing stainless steel bevel gear 407 and stainless steel bevel gear 408, ultimately driving the filter screen 3 to rotate continuously, using centrifugal force to separate impurities from the filter screen 3. The device also includes a sealing assembly 5, which accommodates and seals the stainless steel bevel gear 407 and stainless steel bevel gear 408.

[0030] To achieve effective collection and convenient cleaning of separated impurities, a collection box 403 is installed at the lower part of the sewage treatment pipe 1. A connecting plate 404 is fixedly connected to the upper end of the collection box 403. A fixing bolt 405 passes through the connecting plate 404 to detachably connect the collection box 403 to the sewage treatment pipe 1. A sealing strip 406 is also provided at the connection interface between the collection box 403 and the sewage treatment pipe 1. This structural design allows impurities thrown out by the rotating filter screen 3 to fall into and concentrate inside the collection box 403. At the same time, the sealing strip 406 ensures the sealing of the connection and prevents sewage leakage. When it is necessary to clean the impurities, the collection box 403 can be easily removed and poured out by simply unscrewing the fixing bolt 405. The operation is simple and quick.

[0031] The wastewater treatment device also includes a sealing assembly 5; the sealing assembly 5 includes a sealing box 501 and a fixing block 502. The sealing box 501 houses the meshing parts of the stainless steel bevel gear 407 and the stainless steel bevel gear 408 inside it, and the fixing block 502 is used to fix the sealing box 501 to the wastewater treatment pipe 1. More specifically, in order to achieve sealing of the rotating parts, a fixing ring 503 is fitted on both the rotating shaft 401 and the connecting shaft 409. The fixing ring 503 is rotatably inserted through the box wall of the sealing box 501, and the outer periphery of the fixing ring 503 is sealed with the sealing ring 502. A sealing ring 504 is provided between the inner walls of the housing 501 to achieve dynamic sealing. To further enhance the sealing effect, a rubber ring 505 is also provided between the inner circumference of the sealing ring 504 and the outer circumference of the fixing ring 503. The rubber ring 505 uses its elasticity to radially push the sealing ring 504, so that it fits tightly and fills the gap. In addition, in order to reduce the wear of the sealing ring 504 during rotation, multiple rubber positioning rings 506 are provided on its outer peripheral wall. The rubber positioning rings 506 are used to reduce the contact friction between the sealing ring 504 and the inner wall of the sealing housing 501.

[0032] The axis of the rotating shaft 401 is perpendicular to the axis of the connecting shaft 409. This arrangement allows the rotation driven by the water flow to be effectively converted into a vertical rotation through the bevel gear set, thereby driving the filter screen 3 to rotate.

[0033] Working principle: When sewage containing impurities flows into and through sewage treatment pipe 1, filter screen 3 first intercepts the impurities in the sewage, causing them to adhere to the inner wall surface of filter screen 3, thus achieving preliminary solid-liquid separation.

[0034] Meanwhile, the continuous flow of water impacts the rotating blade 402 in the cleaning assembly 4, which drives the rotating blade 402 and the rotating shaft 401 fixedly connected to it to rotate. The rotation of the rotating shaft 401 drives the stainless steel bevel gear 407 at its end to rotate. Since the stainless steel bevel gear 407 and the stainless steel bevel gear 408 are always in a meshing state, the stainless steel bevel gear 408 rotates in the opposite direction and transmits the rotational motion to the filter screen 3 through the connecting shaft 409, causing the filter screen 3 to rotate at high speed inside the sewage treatment pipe 1. Under the action of centrifugal force generated by the rotation, the impurities that were originally attached to the inner wall of the filter screen 3 are effectively thrown out.

[0035] The ejected impurities fall and collect in the collection box 403 located below due to gravity, realizing automatic cleaning and collection of impurities. During the entire operation, the sealing component 5 completely isolates the stainless steel bevel gear 407 and the stainless steel bevel gear 408 from the sewage environment through the sealing box 501. Relying on the cooperation of the fixing ring 503, sealing ring 504, rubber ring 505 and rubber positioning ring 506, a reliable seal is achieved for the dynamic rotating shaft, preventing corrosion and wear of the mechanism. Through the synergistic effect of the above components, the continuous and automatic cleaning of the filter screen 3 is achieved by utilizing the flow energy of the sewage itself, solving the problems of easy clogging of the filter screen and the need for external power and complex structure of the cleaning device in the prior art.
