Description

Technical Field

[0001] This utility model belongs to the field of wastewater monitoring and treatment technology, specifically relating to a cyclone sludge sedimentation and separation device for wastewater monitoring. Background Technology

[0002] In the field of wastewater monitoring, pollution control, and resource utilization, efficient separation of sludge from wastewater is a crucial step. While traditional cyclone sludge sedimentation equipment can achieve preliminary solid-liquid separation using centrifugal force, it faces significant technical bottlenecks in practical applications: the conventional cyclone chamber has a simple internal flow channel design, resulting in low radial migration efficiency of sludge particles during wastewater cyclone flow, leading to insufficient separation; furthermore, existing filter components mostly use fixed-pore size filters, lacking dynamic anti-clogging mechanisms, making the inlet filter holes prone to clogging by fibrous and colloidal impurities, requiring frequent shutdowns for backwashing, resulting in poor equipment operational stability; simultaneously, the sludge discharge system relies on gravity flow, which easily creates sedimentation dead zones when the sludge moisture content is high, highlighting the problem of incomplete sludge discharge; and the adsorption treatment units are mostly external structures, increasing the equipment's footprint and energy consumption. Utility Model Content

[0003] The purpose of this invention is to provide a cyclone sludge sedimentation and separation device for wastewater monitoring, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cyclone sludge sedimentation and separation device for wastewater monitoring, comprising:

[0005] A cyclone separator tank is provided with an inlet pipe on one side to allow sewage to enter the tank for cyclone sedimentation treatment. A spiral flow channel is provided along the circumference of the inner wall of the cyclone separator tank to separate the sewage and large sludge particles on the outside of the fluid under the action of flow velocity and centrifugal force. An outlet pipe is provided on both sides of the surface of the spiral flow channel to filter in and discharge the sewage into the cyclone.

[0006] The liquid outlet pipe extends through to the upper end of the cyclone separator and is fitted with an adsorption carbon rod that adsorbs impurities in the wastewater by screws. The bottom end of the liquid outlet pipe is connected to a sludge discharge pipe that extends through to the outside of the cyclone separator to discharge sediments in the clean water and perform backwashing. The bottom of the cyclone separator is provided with a sewage discharge pipe that extends through to the outside and is connected to the sludge discharge pipe through a three-way valve A.

[0007] Preferably, the cyclone separator is provided with a drain outlet with two water outlet branches on the rear side. The two water outlet branches penetrate into the interior of the cyclone separator and are connected to the liquid outlet pipe. The drain outlet is provided with a drain valve. By adding a drain outlet and a drain valve, the path of the clean water discharge can be flexibly controlled, which facilitates the diversion monitoring or discharge of the treated clean water, improves the flexibility of the device, and meets the drainage needs under different working conditions.

[0008] Preferably, the outlet pipe is provided with water inlet filter holes evenly distributed in the spiral flow channel, and a baffle plate is provided at the bottom of the spiral flow channel, which is perpendicular to the inside of the cyclone separator, to impede the sewage in the cyclone separator and facilitate the separation of sludge in the sewage. The water inlet filter holes enable the filtration of clean water, while the baffle plate effectively impedes the flow of sewage, prolongs the cyclone time of sewage in the spiral flow channel, and allows sludge particles more time to separate under the action of centrifugal force, thereby improving the separation efficiency.

[0009] Preferably, the sludge discharge pipe is equipped with a three-way valve B for discharging part of the sediment and then switching the flow direction to use an external high-pressure pump to backwash the liquid outlet pipe to prevent clogging of the inlet filter. The three-way valve B can switch the flow direction of the sludge discharge pipe, and the external high-pressure pump can realize the backwashing of the liquid outlet pipe, effectively solving the problem of impurities clogging the inlet filter, ensuring the continuous and stable operation of the equipment, and reducing the number of downtime maintenance.

[0010] Preferably, the three-way valve A is installed on the drain pipe that extends to the outside of the cyclone separator, and the three-way valve A is connected to a common drain pipe that discharges the sludge from the sludge discharge pipe and the sediment inside the cyclone separator simultaneously. This allows the sediment in the sludge discharge pipe and the cyclone separator to be discharged simultaneously, avoiding the formation of dead zones due to sludge deposition, ensuring thorough sludge discharge, and improving sludge treatment efficiency.

[0011] Preferably, the upper end of the adsorption carbon rod is provided with a detachable sealing cap, and after the adsorption carbon rod is installed inside the outlet pipe, the detachable sealing cap is fixed to the end of the outlet pipe with screws. The detachable sealing cap facilitates the installation and replacement of the adsorption carbon rod, and the adsorption carbon rod can be replaced in time when it is saturated, so as to continuously and effectively adsorb impurities in wastewater and ensure the quality of the effluent.

[0012] Preferably, the bottom of the cyclone separator is provided with a cylindrical stable support, and a pressure pump is provided inside the stable support via a strip plate. One end of the pressure pump is connected to an air pipe for pressurizing and quickly discharging the separated sediment, and the other end of the air pipe is sealed and penetrates into the bottom of the cyclone separator and is bent and inclined. The stable support ensures the stability of the device operation, and the pressure pump pressurizes the separated sediment through the air pipe, so that the sludge with high water content is discharged quickly.

[0013] Preferably, the outer front end of the cyclone separator is provided with a maintenance sealing door plate via a hinge, and the maintenance sealing door plate is fixed to the cyclone separator body after being sealed and closed, and is fixed with screws. The maintenance sealing door plate facilitates the staff to inspect, maintain and clean the inside of the device. When a fault occurs or maintenance is required, the door plate can be quickly opened for operation.

[0014] Compared with existing technologies, the technical effects and advantages of this utility model are as follows: This cyclone sludge sedimentation and separation device for wastewater monitoring...

[0015] By setting up spiral flow channels and baffles inside the cyclone separator, the radial migration efficiency of sludge particles under centrifugal force is significantly enhanced by utilizing the principles of fluid dynamics. This extends the cyclone time of the wastewater, allowing large sludge particles to be fully concentrated on the outside of the fluid for separation. Compared with traditional equipment, the separation efficiency of sludge in wastewater is greatly improved, effectively solving the problem of insufficient separation.

[0016] The three-way valve B on the sludge discharge pipe, in conjunction with an external high-pressure pump, can switch the flow direction to perform directional backwashing of the inlet filter holes of the liquid discharge pipe, forming a dynamic anti-clogging mechanism. This effectively prevents fibrous and colloidal impurities from clogging the filter holes, significantly reducing the frequency of equipment shutdowns due to filter hole blockage and greatly improving equipment operational stability and work efficiency.

[0017] The three-way valve A connects to the public sewage pipe, enabling the simultaneous discharge of sediment from the sludge discharge pipe and the cyclone separator tank. Combined with the design of the pressure pump at the bottom of the tank and the inclined air pipe, it changes the traditional gravity-flow sludge discharge method, allowing high-moisture sludge to be discharged quickly, completely eliminating sedimentation dead zones, greatly improving sludge treatment efficiency, and ensuring thorough sludge discharge.

[0018] The removable and sealed pull-out cover design of the adsorption carbon rods facilitates quick replacement of the adsorption carbon rods, ensuring the adsorption effect of wastewater impurities; the setting of the inspection and maintenance sealed door panel makes it convenient for staff to carry out comprehensive inspection, maintenance and cleaning of the inside of the device, reducing the difficulty and cost of equipment maintenance.

[0025] 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.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a cyclone sludge sedimentation and separation device for wastewater monitoring, comprising:

[0027] The cyclone separator 1 is made of high-strength, corrosion-resistant fiberglass. Its inner wall undergoes special polishing treatment, effectively reducing wastewater flow resistance and enhancing wear resistance, thus extending its service life. An inlet pipe 2 is located on one side of the cyclone separator 1, allowing wastewater to enter for cyclone sedimentation. The diameter of the inlet pipe 2 is designed according to the actual wastewater flow rate requirements. A gradually expanding guide structure is installed at the inlet to guide the wastewater smoothly into the tank, reducing the impact of water flow impact on the separation effect. Inside the cyclone separator 1, a spiral flow channel 3 is arranged along the circumference of the inner wall, separating large sludge particles from the outer surface of the fluid under the action of flow velocity and centrifugal force. The spiral flow channel 3 adopts a stepped depth design, gradually increasing in depth towards the bottom of the tank to accommodate the gradually increasing sludge concentration. The surface roughness of the spiral flow channel 3 is strictly controlled at a low level to ensure smooth wastewater cyclone flow. The spiral channel 3 has outlet pipes 4 that allow clean water to filter and flow into the sewage and out to the outside through both sides of its surface. The outlet pipes 4 are made of high-strength PVC pipes and have good chemical stability and anti-aging properties.

[0028] The outlet pipe 4 extends through to the upper end of the cyclone separator 1 and is screwed into which adsorption carbon rods 5 are installed to adsorb impurities present in the wastewater. The adsorption carbon rods 5 are made of fruit shell activated carbon, which has a rich microporous structure and high specific surface area, resulting in high adsorption efficiency. The bottom end of the outlet pipe 4 is connected to a sludge discharge pipe 6 that extends through to the outside of the cyclone separator 1 to discharge sediments in the clean water and for backwashing. The wall thickness of the sludge discharge pipe 6 has been calculated to ensure that it will not rupture during high-pressure backwashing. The bottom of the cyclone separator 1 is provided with a sewage discharge pipe 8 that extends through to the outside and is connected to the sludge discharge pipe 6 via a three-way valve A7. The outlet position of the sewage discharge pipe 8 is lower than the bottom of the cyclone separator 1, using gravity to assist in the discharge of sludge.

[0029] The cyclone separator 1 has a drain outlet 9 with two branch pipes at its rear. The two branch pipes are staggered and run through the interior of the cyclone separator 1, connecting with the liquid outlet pipe 4. This design balances the pressure of the flowing water and reduces water flow fluctuations. The drain outlet 9 is equipped with a drain valve 10, which is an electric butterfly valve that can be remotely controlled, allowing for flexible adjustment of the drainage volume according to processing needs.

[0030] The outlet pipe 4 is uniformly provided with inlet filter holes 11 located within the spiral flow channel 3. The aperture of the inlet filter holes 11 is calculated based on fluid dynamics to ensure smooth passage of clean water while effectively intercepting larger particulate impurities. Furthermore, the spiral flow channel 3 is vertically positioned at the bottom of the cyclone separator 1, where a baffle plate 18 is provided to impede the wastewater in the cyclone separator and facilitate the separation of sludge from the wastewater. The baffle plate 18 is arc-shaped, with its curvature matching that of the spiral flow channel 3, and its surface is provided with guide grooves to guide the wastewater to change its flow direction, thereby enhancing the separation effect between sludge and clean water.

[0031] The sludge discharge pipe 6 is equipped with a three-way valve B12 for discharging some sediment and then switching the flow direction to use an external high-pressure pump to backwash the liquid outlet pipe 4 to prevent the inlet filter hole 11 from becoming clogged. The three-way valve B12 is made of stainless steel, has excellent sealing performance, can withstand high water pressure, and ensures the reliability of the backwashing process.

[0032] The three-way valve A7 is installed on the drain pipe 8 that extends to the outside of the cyclone separator 1. The three-way valve A7 is connected to a common drain pipe 13 that discharges the sludge from the sludge discharge pipe 6 and the sediment inside the cyclone separator 1 simultaneously. The common drain pipe 13 has a large diameter, which can meet the need for rapid discharge of a large amount of sludge. It is wrapped with an insulation layer to prevent the sludge from freezing in winter and affecting the discharge.

[0033] The upper end of the adsorption carbon rod 5 is equipped with a detachable sealing cap 14, which is sealed with a silicone sealing ring to ensure good sealing performance. After the adsorption carbon rod 5 is inserted into the liquid outlet pipe 4, the detachable sealing cap 14 is fixed to the end of the liquid outlet pipe 4 with screws. The screws are anti-loosening screws to prevent loosening during the operation of the device.

[0034] The bottom of the cyclone separator 1 is equipped with a cylindrical, stable support structure made of steel, with shock-absorbing rubber pads at the bottom to effectively reduce vibration and noise during operation. A pressure pump 15 is located inside the stable support structure via a strip plate. The pressure pump 15 is a variable frequency pump, which automatically adjusts the pressure according to the sludge concentration and discharge volume. One end of the pressure pump 15 is connected to an air pipe 16 for pressurizing and rapidly discharging the separated sediment. The air pipe 16 is made of pressure-resistant rubber, is flexible, and not prone to aging. The other end of the air pipe 16 is sealed and extends into the bottom of the cyclone separator 1, and is bent at an angle optimized by fluid dynamics to ensure uniform pressure on the sludge, improving sludge discharge efficiency.

[0035] The outer front end of the cyclone separator 1 is equipped with a maintenance sealing door 17 via a hinge. The edge of the maintenance sealing door 17 is provided with a sealing strip to ensure good sealing performance after closing. After the maintenance sealing door 17 is sealed and closed on the cyclone separator 1, it is fixed with screws. The screw holes are treated with anti-rust to prevent the screws from rusting and affecting the disassembly of the maintenance door 1.

[0036] The outer front end of the cyclone separator 1 is provided with a maintenance sealing door 17 via a hinge, and the maintenance sealing door 17 is sealed and closed on the cyclone separator 1 and then fixed with screws.

[0037] Specifically, during operation, wastewater enters the cyclone separator 1 through the inlet pipe 2 and flows into the spiral channel 3 arranged along the circumference of the inner wall of the tank 1. Guided by the spiral channel 3, the wastewater begins to undergo a spiral swirling motion, generating centrifugal force. Since the density of large sludge particles is greater than that of water, under the action of centrifugal force, the large sludge particles are thrown to the outside of the fluid, gradually moving towards the inner wall of the spiral channel 3 and settling, achieving the initial separation of sludge and water. At the same time, the outlet pipe 4 is installed through both sides of the surface of the spiral channel 3. The outlet pipe 4 has inlet filter holes 11 evenly distributed in the spiral channel 3. The clear water that has undergone preliminary sedimentation enters the outlet pipe 4 through these inlet filter holes 11, completing the initial separation process of clear water and sludge. The clear water can then continue to flow to the upper end of the outlet pipe 4.

[0038] As the clean water enters the outlet pipe 4 and flows upward, it passes over the adsorption carbon rod 5 installed at the upper end of the outlet pipe 4. The adsorption carbon rod 5 has a rich pore structure and strong adsorption capacity, which can effectively adsorb various impurities remaining in the wastewater, such as organic matter and colloids, further purifying the water quality. The purified clean water is discharged from the cyclone separator tank 1 through the connection structure between the outlet pipe 4 and the drain outlet 9, and then through the two outlet branch pipes of the drain outlet 9. The drain valve 10 installed on the drain outlet 9 can control the discharge speed and flow rate of the clean water, which can be easily adjusted according to actual needs.

[0039] Sludge deposited on the inner wall of the spiral flow channel 3 and at the bottom of the cyclone separator 1 is discharged through the sludge discharge pipe 6 and the sewage discharge pipe 8. The bottom end of the sludge discharge pipe 6 is connected to the bottom of the cyclone separator 1. When sludge needs to be discharged, the three-way valve B12 can be controlled to allow the sludge to be discharged through the sludge discharge pipe 6. At the same time, the sewage discharge pipe 8 at the bottom of the cyclone separator 1 is connected to the sludge discharge pipe 6 through the three-way valve A7. The three-way valve A7 is also connected to the common sewage discharge pipe 13, which can realize the synchronous discharge of sludge from the sludge discharge pipe 6 and the sludge inside the cyclone separator 1, allowing for centralized collection and treatment of the sludge. In addition, the pressure pump 15 at the bottom of the cyclone separator 1 provides pressure to the inside of the tank through the air pipe 16. The air pipe 16 is bent and inclined, which can more efficiently push the sludge at the bottom of the tank to the sewage discharge pipe 8 and the sludge discharge pipe 6, accelerating the sludge discharge process and improving sludge treatment efficiency.

[0040] To prevent impurities from clogging the inlet filter holes 11 on the outlet pipe 4 and affecting the water filtration effect, the device is equipped with a backwashing function. When backwashing is required, the flow direction of the sludge discharge pipe 6 is switched by controlling the three-way valve B12. A high-pressure water flow is injected into the sludge discharge pipe 6 using an external high-pressure pump. The high-pressure water flow flows in the opposite direction through the outlet pipe 4, powerfully flushing the inlet filter holes 11, washing away the impurities attached to the filter holes, restoring the inlet filter holes 11 to unobstructed flow, and ensuring the continuous and stable operation of the device.

[0041] The maintenance sealing door 17, hinged to the front of the hydrocyclone separator 1, facilitates internal maintenance and repair. When internal inspection, cleaning, or component replacement is required, the maintenance sealing door 17 can be opened, allowing personnel to enter the tank for operation. After completion, the maintenance sealing door 17 is sealed and secured with screws to ensure the unit's airtightness and safety. The detachable sealing pull-out cover 14 at the top of the adsorption carbon rod 5 facilitates replacement and maintenance. When the adsorption capacity of the adsorption carbon rod 5 decreases, the screws can be unscrewed, the detachable sealing pull-out cover 14 opened, the old adsorption carbon rod 5 removed, and a new one replaced, ensuring the unit's impurity adsorption effect.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
