Description

Technical Field

[0001] The present invention relates to the field of separation equipment, and particularly to a separator with functions of separating particles and cleaning a filter element. Background Art

[0002] A separator is a machine that separates a mixture into two or more different substances. Common separators include centrifugal separators and electrostatic separators. Traditional separators can only separate large and heavy particles, and only a part of the particles can be separated. There are still some small particles and floating substances that block the filter used for filtration, reducing the use effect of the separator. Summary of the Invention

[0003] The object of the present invention is to propose a separator with functions of separating particles and cleaning a filter element in view of the problems in the background art.

[0004] The technical solution of the present invention: On the one hand, a separator with functions of separating particles and cleaning a filter element is proposed, which includes a tank body, a filtering part, a fixing seat, an ultrasonic generator and a funnel;

[0005] There are two filtering parts; the two filtering parts, the fixing seat and the funnel are all located in the tank body and are connected to the inner wall of the tank body. The two filtering parts, the fixing seat and the funnel are used to divide the interior of the tank body into a water outlet chamber, a filtering chamber, a liquid inlet chamber, a separation chamber and a sewage collection chamber from top to bottom in sequence;

[0006] The water outlet chamber is provided with a water outlet on the tank body;

[0007] Activated carbon is filled in the filtering chamber;

[0008] The fixing seat is located on the end face of the separation chamber and is detachably provided with a filter element;

[0009] The liquid inlet chamber is provided with elbows on the tank body; there are two elbows; the two elbows are distributed in a clockwise or counterclockwise direction;

[0010] The ultrasonic generator is connected to the inner wall of the liquid inlet chamber, and the ultrasonic generator is located above the funnel;

[0011] The sewage collection chamber is provided with a sewage outlet on the lower end face of the tank body; a sewage discharge valve is provided at the sewage outlet.

[0012] Preferably, the liquid inlet chamber is provided with a window on the tank body.

[0013] Preferably, each filtering part is selected as a filter mesh.

[0014] Preferably, it further includes a plurality of fastening members; the tank body includes an upper tank and a lower tank;

[0015] Flange plates are provided at the ports of the upper tank and the lower tank; the flange plates on the upper tank and the lower tank are mutually attached and connected through a plurality of fastening members.

[0016] Preferably, the frustum-shaped structure of the fixed seat, and one end with a large diameter of the fixed seat is connected to the inner wall of the lower tank.

[0017] Preferably, it further includes a nut; one end with a small diameter of the fixed seat is provided with a port for the filter element to be press-fitted and inserted, and a bracket is arranged inside the fixed seat; a threaded hole is arranged on the bracket;

[0018] A screw rod is arranged at the center of the filter element; the screw rod passes through the threaded hole in a threaded manner;

[0019] The nut is threadedly sleeved on the outer side of the screw rod, and the end face of the nut presses against the bracket.

[0020] On the other hand, a method for using a separator with the functions of separating particles and cleaning the filter element is proposed, including the above-mentioned separator with the functions of separating particles and cleaning the filter element, specifically including the following steps:

[0021] S1. Introduce high-pressure water into the separation chamber from the two elbows. The elbows change the flow direction of the high-pressure water so that the high-pressure water flows along the inner wall of the separation chamber to form a vortex;

[0022] The particulate matters in the high-pressure water flowing in a vortex enter the funnel along the inner wall of the separation chamber and sink to the sewage collection chamber along the inner wall of the funnel;

[0023] The high-pressure water flowing in a vortex contacts the filter element and is filtered. The filtered water enters the liquid inlet chamber and is filtered by the lower filtering part and then enters the filtering chamber to contact the activated carbon for purification. The purified water passes through the upper filtering part and enters the water outlet chamber, and finally is discharged from the water outlet;

[0024] S3. When discharging sewage, start the ultrasonic generator and open the sewage discharge valve;

[0025] When the sewage discharge valve is opened, the pressure in the sewage collection chamber and the separation chamber is instantaneously reduced. The instantaneous pressure reduction forms a pulsed jitter and the water in the liquid inlet chamber and the collecting tank flows back, flushing the filter element;

[0026] The ultrasonic generator converts the acoustic energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and radiates the ultrasonic waves into the tank through the cleaning tank wall, so that the microbubbles in the liquid in the tank can maintain vibration under the action of the sound waves;

[0027] When the sound intensity decreases due to the pressure reduction to a certain extent, the microbubbles expand rapidly and then suddenly close; a shock wave is generated at the moment when the microbubbles close, generating a pressure of 1000-1020 Pa around the bubbles.

[0028] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0029] The separator provided by the present invention can change the flow direction of the high-pressure water to be treated, so that the high-pressure water entering the tank forms a vortex, and the physical principle is used to slowly sink the particulate impurities in the high-pressure water along the inner walls of the separation chamber and the funnel into the sewage collection chamber, realizing the solid-liquid separation of the high-pressure water; the high-pressure water flowing in a vortex contacts the filter element and is filtered. Since the water is flowing in a swirl, the flowing water can clean the filter element; during sewage discharge, the pressure in the sewage collection chamber and the separation chamber is instantaneously reduced, and the instantaneous pressure reduction forms a pulsed jitter and the water in the liquid inlet chamber and the tank flows back, flushing the filter element. At this time, under the action of the ultrasonic generator, the microbubbles in the liquid in the tank can maintain vibration under the action of the sound wave; when the sound pressure or sound intensity decreases due to pressure to a certain extent, the microbubbles rapidly expand and then suddenly close; a shock wave is generated at the moment when the microbubbles close, generating a pressure of 1000-1020 Pa and local temperature adjustment around the bubbles. The huge pressure generated by this ultrasonic cavitation can break the insoluble dirt and make them disperse in the solution. Through the above method, on the one hand, the adsorption between the dirt and the surface of the filter element is destroyed, and on the other hand, the fatigue damage of the dirt layer can be caused and peeled off, realizing the effect of cleaning the dirt on the surface of the filter element; the vibration of the gas-type microbubbles scrubs the solid surface. Once there is a gap between the dirt layer and the solid surface, the bubbles immediately drill into the above-mentioned gap for vibration, causing the dirt layer to fall off from the solid surface, thereby ensuring the cleanliness of the surface of the filter element, greatly improving the use effect of the filter element, and solving the technical problem that small particles and floating substances block the filter element during the solid-liquid separation process in the prior art.

[0052] Embodiment Three

[0053] A method for using a separator with the functions of separating particles and cleaning the filter element proposed by the present invention includes the separator with the functions of separating particles and cleaning the filter element described in Embodiment Two, and specifically includes the following steps:

[0054] S1. Inject high-pressure water into the separation chamber 104 from two elbows 4. The elbows 4 change the flow direction of the high-pressure water so that the high-pressure water flows along the inner wall of the separation chamber 104 to form a vortex;

[0055] S2. The particulate matter in the high-pressure water flowing in a vortex enters the funnel 11 along the inner wall of the separation chamber 104 and sinks along the inner wall of the funnel 11 into the sewage collection chamber 105;

[0056] The high-pressure water flowing in a vortex contacts the filter element 8 and is filtered. The filtered water enters the liquid inlet chamber 102, is filtered by the lower filter part 3, enters the filter chamber 101, contacts the activated carbon for purification, and the purified water passes through the upper filter part 3 and enters the water outlet chamber, and finally is discharged from the water outlet 2;

[0057] S3. During sewage discharge, start the ultrasonic generator 10 and open the sewage discharge valve;

[0058] When the sewage discharge valve is opened, the pressure in the sewage collection chamber 105 and the separation chamber 104 is instantaneously reduced. The instantaneous pressure reduction forms a pulsed jitter and the water in the liquid inlet chamber 102 and the tank body flows back, flushing the filter element 8;

[0059] The ultrasonic generator 10 converts the acoustic energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and radiates the ultrasonic wave into the tank through the cleaning tank wall, so that the microbubbles in the liquid in the tank can maintain vibration under the action of the sound wave;

[0060] When the sound pressure or sound intensity reaches a certain degree due to the pressure reduction, the microbubbles expand rapidly and then suddenly close; a shock wave is generated at the moment when the microbubbles close, generating a pressure of 1000 - 1020 Pa and local temperature adjustment around the bubbles.

[0061] In summary, in the present invention, the water to be separated is pumped into the separation chamber 104 from the two elbows 4 by means of a high-pressure pump. The elbows 4 change the flow direction of the high-pressure water so that the high-pressure water flows along the inner wall of the separation chamber 104 to form a vortex. Using physical principles, the particulate impurities in the high-pressure water slowly sink along the inner walls of the separation chamber 104 and the funnel 11 into the sewage collection chamber 105, achieving the solid-liquid separation of the high-pressure water;

[0062] The relatively clean water in the vortex core is separated again by the filter element 8, that is, the high-pressure water flowing in a vortex contacts the filter element 8 and is filtered. Since the water is flowing in a swirl, the flowing water can clean the filter element. The filtered water enters the liquid inlet chamber 102 and is filtered by the lower filter part 3 and then enters the filter chamber 101 to contact the activated carbon for purification. The purified water passes through the upper filter part 3 and enters the water outlet chamber, and finally is discharged from the water outlet 2;

[0063] When the sewage discharge valve is opened, the pressure in the sewage collection chamber 105 and the separation chamber 104 is instantaneously reduced. The instantaneous pressure reduction forms a pulsed jitter and the water in the liquid inlet chamber 102 and the tank body flows back, flushing the filter element 8;

[0064] During the process of backwashing the filter element 8, the ultrasonic generator 10 converts the acoustic energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and radiates the ultrasonic waves into the tank through the cleaning tank wall. Due to the radiation of the ultrasonic waves, the microbubbles in the liquid in the tank can maintain vibration under the action of the sound waves;

[0065] When the sound pressure or sound intensity decreases due to pressure to a certain extent, the microbubbles rapidly expand and then suddenly close; at the moment when the microbubbles close, a shock wave is generated, generating a pressure of 1000 - 1020 Pa and local temperature adjustment around the bubbles. The huge pressure generated by this ultrasonic cavitation can destroy the insoluble dirt and cause them to be differentiated in the solution. Through the above methods, on the one hand, the adsorption between the dirt and the surface of the filter element 8 is destroyed, and on the other hand, the fatigue damage of the dirt layer can be caused and peeled off, achieving the effect of cleaning the dirt on the surface of the filter element 8; the vibration of the gas-type microbubbles scrubs the solid surface. Once there is a gap between the dirt layer and the solid surface, the bubbles immediately drill into the above-mentioned gap for vibration to make the dirt layer fall off from the solid surface;

[0066] Due to the cavitation effect, the two liquids are rapidly dispersed and emulsified at the interface. When the solid particles are wrapped and adhered to the surface of the filter element, the oil is emulsified and the solid particles fall off by themselves. When the ultrasonic wave propagates in the cleaning liquid, positive and negative alternating sound pressures are generated, forming a jet flow that impacts the filter element 8. At the same time, due to the non-linear effect, acoustic streaming and micro-acoustic streaming will be generated, and ultrasonic cavitation will generate a high-speed micro-jet flow at the solid-liquid interface. All these effects can destroy the dirt, remove or weaken the boundary dirt layer, increase the stirring and diffusion effects, accelerate the dissolution of soluble dirt, and at the same time the vortex water separates and discharges the dirt, keeping the filter element 8 clean.

[0067] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the relevant art.
