Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a multi-stage separation device for industrial grease. Background Art

[0002] Against the backdrop of accelerating global industrialization, the scale of industrial production continues to expand, and the discharge of industrial wastewater is also increasing day by day. Industrial wastewater comes from a wide range of sources, covering many industries such as food processing, petrochemicals, and machinery manufacturing. These wastewaters have complex compositions and contain a large amount of harmful substances, among which grease is one of the pollutants that cannot be ignored. Direct discharge of oily wastewater will cause extremely serious and widespread harm to the ecological environment, so it is necessary to treat the grease in industrial wastewater.

[0003] For example, a Chinese patent with publication number CN118062940A discloses a multi-stage separation device for industrial grease, comprising a fixed bracket, a mixing drum is fixedly connected to the fixed bracket, a control panel is fixedly provided on the outer side of the mixing drum, and an observation window is embedded and connected to the side of the mixing drum on one side of the control panel. A stirring mechanism is provided inside the mixing drum, and the floating oil on the water surface centrifugally separated inside the mixing drum can be adsorbed and separated by the adsorption separation mechanism, and an external surfactant is sprayed into the mixing drum through a three-way solenoid valve to emulsify the emulsified oil inside the mixing drum, so that the emulsified oil can float, thereby realizing the separation of the emulsified oil;

[0004] Although the above technology can achieve the separation of grease in sewage to a certain extent, when the adsorption separation mechanism absorbs grease, due to the tension of the sewage itself, it is impossible to accurately absorb the grease at the liquid surface position where the grease and sewage are separated, resulting in incomplete grease separation and affecting the effect of grease treatment in sewage.

[0005] For example, a Chinese patent with a Chinese publication number of CN108793474A discloses an oil removal and purification device for wastewater in the catering industry, which includes a box body, a plurality of supporting feet connected to the lower end of the box body, a sewage inlet connected to the side wall of the box body, a solid sewage outlet connected to the side wall of the box body, and a water outlet connected to the other side wall of the box body. The technology uses oil absorption felt to suck out the oil in the box body, and then squeezes the rubber ring to make the oil fall into the detergent box and be discharged through the oil discharge impeller, thereby achieving the effect of removing oil and purifying sewage;

[0006] Although the above technology absorbs grease in sewage through oil absorbent felt, the gaps between the oil absorbent felt fibers will be compressed due to the reciprocating squeezing of the oil absorbent felt, resulting in a decrease in porosity. In this way, the total surface area and available pores of the oil absorbent felt are reduced, thereby reducing its oil absorption capacity and efficiency.

[0007] To this end, the present invention provides a multi-stage separation device for industrial grease. Summary of the invention

[0033] 1. The present invention provides a partition plate, which is fixedly mounted on the inner wall of the demulsification tank.

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] like Figures 1 to 10 As shown, a multi-stage separation device for industrial grease according to an embodiment of the present invention includes a reaction part, a material guiding part, an adsorption mechanism, a control mechanism, a heating mechanism, an exhaust mechanism and a collection mechanism.

[0049] The reaction part comprises a demulsification tank 1 and a partition plate 8. The partition plate 8 is fixedly mounted on the inner wall of the demulsification tank 1. The inner cavity of the demulsification tank 1 is divided into two independent chambers by the partition plate 8.

[0050] The material guiding mechanism includes a sewage inlet pipe 10 and a flotation port 9. One end of the sewage inlet pipe 10 extends to the inner cavity of the demulsification tank 1. The sewage inlet pipe 10 is used to discharge the oily sewage into the chamber on one side of the partition plate 8. An aeration pipe is arranged in the chamber. After the sewage is injected, a demulsifier is added, and then aeration is performed through the aeration pipe to mix the sewage and the demulsifier. The flotation port 9 is opened on the side wall of the demulsification tank 1. The oily foam is removed from the flotation port 9 through a flotation machine (not shown in the figure) (the flotation machine floats the foam in the sewage, which is a common technical means in the prior art, so its working principle will not be described in detail), thereby realizing the preliminary treatment of grease in the sewage.

[0051] The adsorption mechanism includes a bearing shaft 11, a support tube 4 and an oil-absorbing felt 3. The oil-absorbing felt 3 is detachably mounted on the radial outer wall of the support tube 4. In the present embodiment, the oil-absorbing felt 3 is fixed to the support tube 4 by Velcro to facilitate replacement of the oil-absorbing felt 3, wherein the oil-absorbing felt 3 is arranged in the chamber on the other side of the partition plate 8, and a water pump is arranged at the upper end of the partition plate 8. The sewage after preliminary treatment is transported to the chamber on the other side of the partition plate 8 by the water pump, and the residual grease is absorbed by the oil-absorbing felt 3. Compared with the prior art (Chinese patent with publication number CN118062940A) in which the upper layer of grease is sucked out, the efficiency of grease treatment in sewage can be effectively improved by initially using a demulsifier to treat the sewage and then absorbing the grease through the oil-absorbing felt 3.

[0052] The bearing shaft 11 is fixedly mounted on one axial end of the supporting cylinder 4 and is rotatably connected to the side wall of the demulsification tank 1. The supporting cylinder 4 and the oil absorption felt 3 are driven by rotating the bearing shaft 11, so that different positions of the oil absorption felt 3 can enter the initially treated sewage, so that the oil absorption felt 3 can evenly absorb the grease in the sewage, thereby realizing the multi-stage separation of grease in industrial sewage.

[0053] The exhaust mechanism includes a mounting tube 16, a heating port 14 and an exhaust port 15. The heating port 14 and the exhaust port 15 are both opened on the radial outer wall of the mounting tube 16. The mounting tube 16 is rotatably mounted on the inner wall of the supporting tube 4, and heated air is injected into the mounting tube 16. The heated air is discharged through the heating port 14 and the exhaust port 15. The outer wall of the supporting tube 4 is hollowed out to facilitate the hot air discharged from the heating port 14 and the exhaust port 15 to be transported to the interior of the oil-absorbing felt 3.

[0054] The collecting mechanism includes a top pressure roller 27, a collecting trough 26 and a support frame 2. The support frame 2 is fixedly installed on the outer wall of the demulsification tank 1. The top pressure roller 27 and the collecting trough 26 are both slidably arranged at the bottom of the support frame 2. The support frame 2 provides installation and support for the top pressure roller 27 and the collecting trough 26.

[0055] Among them, the upper end of the collecting tank 26 is provided with an opening, and is located directly below the top pressure roller 27. The interior of the collecting tank 26 is connected with an external grease collection chamber through a conduit. After the oil-absorbing felt 3 fully absorbs the grease, the sliding top pressure roller 27 presses the outer wall of the rotating oil-absorbing felt 3 to squeeze out the grease absorbed by the oil-absorbing felt 3 and drip it into the inner cavity of the collecting tank 26, so that the oil-absorbing felt 3 can absorb the grease again.

[0056] It should be noted that, in actual operation, the direction of the oil-absorbing felt 3 needs to be controlled, and it should be rotated from the bottom of the top pressure roller 27 to the top to prevent the extruded grease from accumulating above the top pressure roller 27 .

[0057] The heating mechanism is used to convey heated air to the inner cavity of the mounting cylinder 16, wherein when the top pressure roller 27 squeezes the oil-absorbing felt 3, the heating port 14 is located below the squeezing portion, thereby heating the oil-absorbing felt 3 first and then squeezing and draining the oil. Heating the oil-absorbing felt 3 can improve the fluidity of the oil absorbed in the fiber, reduce the viscosity, and further improve the efficiency of oil drainage by squeezing, so as to adapt to the outdoor low temperature environment.

[0058] As the oil-absorbing felt 3 rotates, the squeezed part gradually moves to the exhaust port 15, and hot air blows toward the squeezed oil-absorbing felt 3 at this time. On the one hand, the recoil cleaning of the oil-absorbing felt 3 is realized, and on the other hand, the injection of hot air can make the fibers expand under the action of hot air, restore a certain elasticity and fluffiness, reduce the mechanical stress generated by the squeezing process, prevent the deformation and breakage of the internal fibers of the oil-absorbing felt 3, and extend the service life of the oil-absorbing felt 3. Compared with the prior art (Chinese patent with publication number CN108793474A), the method of only reciprocatingly squeezing the oil-absorbing felt 3 can effectively prevent the porosity from decreasing, maintain the oil absorption effect of the oil-absorbing felt 3 and extend its service life, thereby improving the efficiency of grease separation in sewage.

[0059] The control mechanism is used to control the intermittent rotation of the bearing shaft 11. The intermittent rotation of the bearing shaft 11 drives the oil-absorbing felt 3 to rotate intermittently, which can extend the contact time between the oil-absorbing felt 3 and the sewage so that the oil-absorbing felt 3 can fully absorb the grease in the sewage.

[0060] As a preferred embodiment of the present invention, a conveying cylinder 12 is fixedly installed on the upper side of the demulsification tank 1. The conveying cylinder 12 passes through the mounting cylinder 16 and is fixedly connected to the mounting cylinder 16, so as to provide support for the mounting cylinder 16, thereby keeping the mounting cylinder 16 in a fixed position when the support cylinder 4 rotates. As the support cylinder 4 drives the oil absorption felt 3 to rotate, it is convenient to exhaust air toward different parts of the oil absorption felt 3.

[0061] The inner cavity of the mounting cylinder 16 is fixedly mounted with a control cylinder 17 . The inner cavity of the control cylinder 17 is communicated with the inner cavity of the conveying cylinder 12 . Heated air is injected into the control cylinder 17 through the conveying cylinder 12 .

[0062] An exhaust hole is opened on the radial outer wall of the control cylinder 17, and a sealing plug 21 for sealing the exhaust hole is elastically provided on the outer wall of the control cylinder 17. The sealing plug 21 is slid until the sealing plug 21 is separated from the exhaust hole. At this time, the hot air inside the control cylinder 17 is discharged to the inner cavity of the mounting cylinder 16 through the exhaust hole.

[0063] A connecting plate 20 is fixedly installed on the outer wall of the sealing plug 21. There are multiple sealing plugs 21, and the multiple sealing plugs 21 are connected by the connecting plate 20, wherein the number of exhaust holes is consistent with the number of sealing plugs 21. The connecting plate 20 is provided to facilitate the control of the synchronous movement of the multiple sealing plugs 21, thereby achieving simultaneous conduction of the multiple exhaust holes for uniform exhaust.

[0064] The heating mechanism includes a heating box 5 , a heating plate 36 and a control pump 38 .

[0065] The heating box 5 is fixedly installed on the outer wall of the demulsification tank 1, wherein the heating box 5 is used to store heat exchange liquid (pure water is selected). A liquid inlet pipe is arranged outside the heating box 5 to replenish the heat exchange liquid into the heating box 5. After replenishment, the liquid inlet pipe needs to be blocked.

[0066] The heating plate 36 is fixedly mounted on the inner wall of the heating box 5 . The heating plate 36 is a resistance heater, and copper plates parallel to each other are arranged at its heating end, so as to heat the heat exchange fluid inside the heating box 5 .

[0067] The control pump 38 is fixedly installed on the outer wall of the heating box 5. The control pump 38 is used to extract the air heated by the heating plate 36. A copper tube is arranged in an "S" shape inside the copper plate. Both ends of the copper tube extend to the outside of the heating box 5. The input end of the control pump 38 is connected to one end of the copper tube.

[0068] The output end of the control pump 38 is connected to one axial end of the conveying cylinder 12 through a conduit. When the control pump 38 absorbs external air and injects it into the interior of the conveying cylinder 12, the air is heated in the copper tube, thereby injecting heated air into the conveying cylinder 12 to achieve the effect of heating the oil-absorbing felt 3.

[0069] As a preferred embodiment of the present invention, the control mechanism includes a transmission ratchet 6 , a locking ratchet rod 33 , a mounting crossbeam 30 and a control lever 34 .

[0070] The middle part of the installation beam 30 is rotatably connected to the side wall of the demulsification tank 1 through an elastic member, and the elastic member is a torsion spring. After the installation beam 30 is rotated, the installation beam 30 is controlled to return to its original position through elastic force.

[0071] The transmission ratchet 6 is fixedly connected to the outer wall of the load-bearing shaft 11, and the locking ratchet rod 33 is rotatably installed on the outer wall of the demulsification tank 1, and one end is in real-time contact with the outer wall of the transmission ratchet 6. The locking ratchet rod 33 is engaged with the transmission ratchet 6 to limit the rotation direction of the load-bearing shaft 11.

[0072] The control lever 34 is rotatably mounted on the outer wall of the mounting beam 30. A protrusion is provided on the outside of the mounting beam 30, and the protrusion is located above the control lever 34, so that the control lever 34 can only rotate in one direction on the outer wall of the mounting beam 30. At the same time, the control lever 34 is rotatably connected to the mounting beam 30 through a torsion spring. After the control lever 34 is rotated, the elastic force of the torsion spring drives the control lever 34 to reset to fit with the protrusion on the outside of the mounting beam 30.

[0073] When it is necessary to control the rotation of the load-bearing shaft 11, press the end of the mounting beam 30 away from the control lever 34. At this time, the other end of the mounting beam 30 drives the control lever 34 to lift, and the transmission ratchet 6 is deflected by the control lever 34 (the deflection distance is not less than one tooth pitch of the transmission ratchet 6), and drives the load-bearing shaft 11 to deflect, and then release the mounting beam 30, and the mounting beam 30 is reset. At this time, the control lever 34 and the transmission ratchet 6 slip, and the locking ratchet rod 33 locks the transmission ratchet 6 unidirectionally. By controlling the reciprocating deflection of the mounting beam 30, the intermittent rotation of the load-bearing shaft 11 and the oil-absorbing felt 3 is controlled.

[0074] As a preferred embodiment of the present invention, a pressure relief cylinder 32 is fixedly installed on the outer wall of the heating box 5. When the heat exchange fluid inside the heating box 5 is heated, the air pressure inside the heating box 5 increases. At this time, the gas is discharged through the pressure relief cylinder 32 to achieve pressure relief of the heating box 5.

[0075] A conical plug 35 is elastically installed on the inner wall of the pressure relief cylinder 32. A conical hole adapted to the conical plug 35 is opened on the inner wall of the pressure relief cylinder 32. The conical plug 35 is connected to the pressure relief cylinder 32 through a spring. The elastic force of the spring controls the conical plug 35 to have a real-time tendency to fit the conical hole. When the internal air pressure of the heating box 5 increases, the conical plug 35 is pushed to separate from the conical hole, thereby realizing the conduction and pressure relief of the pressure relief cylinder 32.

[0076] As the heating of the interior of the heating box 5 continues, the conical plug 35 is affected by the elastic force and the internal pressure of the heating box 5 and slides back and forth along the inner cavity of the pressure relief cylinder 32. The transmission rod 31 is fixedly installed on the upper end surface of the conical plug 35, and the transmission rod 31 is driven by the conical plug 35 to slide back and forth.

[0077] A waist-shaped groove is provided at one end of the mounting beam 30 away from the control lever 34, and a pin shaft slidingly matched with the waist-shaped groove is fixedly installed on the outer wall of the transmission rod 31. The outer wall of the pin shaft slides and fits with the inner wall of the waist-shaped groove. When the transmission rod 31 slides back and forth, the mounting beam 30 is driven to deflect back and forth, thereby controlling the intermittent rotation of the load-bearing shaft 11 and the oil-absorbing felt 3, and utilizing the useless pressure generated when the heating box 5 is heated internally to drive the oil-absorbing felt 3 to rotate intermittently, thereby improving the energy utilization efficiency.

[0078] As a preferred embodiment of the present invention, a control plate 19 is slidably provided on the inner wall of the control cylinder 17, a connecting rod is fixedly installed on the ground of the sealing plug 21, a sliding rod 22 slidably matched with a guide groove 23 is fixedly installed on the outer wall of the connecting rod, and the connecting rod is slid along the axis (vertical direction) of the sealing plug 21, thereby controlling the separation and sealing of the sealing plug 21 and the exhaust hole.

[0079] The two ends of the guide groove 23 are parallel to each other and the middle part is inclined. The control plate 19 is slid in the horizontal direction to drive the slide bar 22 to slide along the inside of the guide groove 23. When the slide bar 22 slides to the lowest end of the guide groove 23 (the horizontal section of the guide groove 23), the sealing plug 21 fits tightly against the exhaust hole (the sealing plug 21 is made of elastic rubber material). When the slide bar 22 slides to the highest position of the guide groove 23 (the other horizontal section of the guide groove 23), the sealing plug 21 is separated from the exhaust hole. When the slide bar 22 slides to the two horizontal sections of the guide groove 23, the connecting rod and the sealing plug 21 are prevented from sliding in the vertical direction.

[0080] When squeezing the oil-absorbing felt 3, controlling the exhaust hole to be turned on relative to the exhaust hole being turned on in real time can prevent the exhaust hole from exhausting the grease absorbed by the oil-absorbing felt 3 when the oil-absorbing felt 3 absorbs oil.

[0081] An accommodating cylinder 7 is fixedly mounted on one axial end of the control cylinder 17 , and a control plug 18 is elastically mounted on the inner wall of the accommodating cylinder 7 . The control plug 18 is connected to the accommodating cylinder 7 via a spring, and the inner cavity of the accommodating cylinder 7 is connected to the inner cavity of the control cylinder 17 .

[0082] A transmission plate 40 is fixedly mounted on the outer wall of the control plug 18 , a sliding block 39 slidably connected to the control plate 19 is fixedly mounted on the outer wall of the transmission plate 40 , and a sliding groove for the sliding block 39 to slide is provided on the side wall of the control plate 19 .

[0083] When hot air is injected into the control cylinder 17, the air pressure in the inner cavity of the control cylinder 17 increases, pushing the control plug 18 to slide, and driving the transmission plate 40 and the sliding block 39 to slide, until the sliding block 39 pushes a side wall of the slide groove, thereby driving the control plate 19 to slide, until the slide rod 22 slides to the highest position of the guide groove 23, at which time the exhaust hole is connected, and the control cylinder 17 exhausts air outwards.

[0084] As the control cylinder 17 is exhausted, the internal air pressure decreases. At this time, the elastic force of the spring pushes the control plug 18 to slide in the opposite direction until the sliding block 39 pushes the other side wall of the slide groove, thereby driving the control plate 19 to slide in the opposite direction until the slide rod 22 slides to the lowest position of the guide groove 23. At this time, the exhaust hole is blocked, and the inner cavity of the control cylinder 17 begins to be inflated, so that when the conveying cylinder 12 continues to convey hot air, the control cylinder 17 is reciprocatedly and alternately inflated and exhausted.

[0085] At the same time, the exhaust time is extended by sliding of the sliding block 39, and the exhaust time is consistent with the time when the top pressure roller 27 squeezes the oil-absorbing felt 3, so as to maintain sufficient squeezing time.

[0086] As a preferred embodiment of the present invention, a sliding frame 25 is slidably mounted on the bottom surface of the support frame 2 , and a T-shaped block is provided on the upper end of the sliding frame 25 and is slidably plugged with the bottom surface of the support frame 2 .

[0087] The axial ends of the top pressure roller 27 are rotatably connected to the side walls of the sliding frame 25, and the side walls of the collecting trough 26 are fixedly connected to the side walls of the sliding frame 25. The sliding adjustment sliding frame 25 drives the top pressure roller 27 and the collecting trough 26 to slide.

[0088] A control tube 24 is fixedly mounted on the bottom surface of the support frame 2. A guide plug 28 is elastically mounted in the inner cavity of the control tube 24. The guide plug 28 is connected to the inner wall of the control tube 24 via a spring. After the guide plug 28 is slid, it is driven by the spring to reset.

[0089] The radial outer wall of the guide plug 28 is sealed with the inner wall of the control tube 24, and a connecting shaft 29 is fixedly installed on the outer wall of the guide plug 28, and the other end of the connecting shaft 29 is fixedly connected to the outer wall of the sliding frame 25. The sliding guide plug 28 controls the sliding of the sliding frame 25 through the connecting shaft 29, and then controls the sliding of the top pressure roller 27.

[0090] A switching cylinder 13 is fixedly mounted on one end of the delivery cylinder 12 , and the other end of the switching cylinder 13 is connected to the inner cavity of the control cylinder 17 , so that the inner cavity pressure of the control cylinder 17 can be adjusted synchronously by adjusting the inner cavity pressure of the switching cylinder 13 .

[0091] A sliding plug 37 is elastically installed in the inner cavity of the adapter tube 13 , and the sliding plug 37 is connected to the inner cavity of the adapter tube 13 via a spring.

[0092] The axial end of the adapter cylinder 13 is connected to the inner cavity of the control tube 24 through a hose. The chamber connecting the adapter cylinder 13 and the control tube 24 is filled with hydraulic oil. When the sealing plug 21 blocks the exhaust hole and the control pump 38 delivers hot air to the control cylinder 17, the pressure in the inner cavity of the control cylinder 17 increases, causing the sliding plug 37 to slide. At this time, the hydraulic oil is pushed, causing the guide plug 28 in the control tube 24 to drive the sliding frame 25 to move in a direction away from the oil-absorbing felt 3, so that the top pressure roller 27 is separated from the oil-absorbing felt 3.

[0093] When the sealing plug 21 is separated from the exhaust hole, the internal pressure of the control cylinder 17 and the adapter cylinder 13 is reduced, and the spring pushes the sliding plug 37 to slide in the opposite direction, driving the guide plug 28 to slide in the opposite direction, so that the top pressure roller 27 slides toward the oil-absorbing felt 3 and squeezes the oil-absorbing felt 3, thereby realizing the simultaneous squeezing and draining of oil from the oil-absorbing felt 3 and blowing hot air to the oil-absorbing felt 3.

[0094] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
