Description

Technical Field

[0001] This utility model belongs to the field of oil-water separation, and specifically relates to the field of oil-water separation for separating floating oil on the liquid surface. Background Technology

[0002] While current oil skimming and separation devices offer powerful skimming capabilities, quickly extracting various oily processing fluids from machine tool water tanks and separating the floating oil from the surface, they rely on overflow for oil removal. Typically, when the amount of floating oil on the surface of the settling tank reaches a certain level, the effective height of the outlet pipe in the return tank is adjusted to allow the oil to enter the collection tank. When the amount of floating oil on the surface of the settling tank is low, the effective height of the outlet pipe is manually adjusted to prevent liquid from entering the collection tank. Therefore, overflow oil removal requires manual operation, and the skimmed oil has a high liquid content, resulting in low skimming efficiency.

[0003] Some products on the market use steel strips for degreasing, but the contact area between the steel strip and the oil is small, resulting in limited oil removal. Furthermore, the steel strips are relatively thin, requiring welding at the joints, which is difficult and costly to manufacture. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic oil removal mechanism and an oil-water separation device, which enhances the cleaning function of surface floating oil, reduces the liquid content in the skimmed oil, and achieves automatic oil removal while ensuring that the original functions and costs of the equipment remain unchanged.

[0005] Based on the above problems, the proposed solution is as follows:

[0006] An automatic oil removal mechanism includes:

[0007] The cover plate has a clearance channel at the bottom;

[0008] A rotating disk is provided with a rotating shaft, which passes through the cover plate; the rotating disk extends out of the clearance channel;

[0009] Scraper assemblies are disposed on both sides of the rotating disk; the scraper assemblies on both sides of the rotating disk are at different heights;

[0010] An inclined slide is provided with the rotating disk clearance groove, and the scraper assembly is adjustablely connected to the inclined slide.

[0011] An oil receiving groove is located below the inclined slide groove and is fixedly installed with the cover plate.

[0012] Preferably, the scraper assembly includes a scraper and a scraper seat, the scraper is connected to the scraper seat, and the scraper's position relative to the scraper seat in the height direction is adjustable; the scraper seat's position relative to the inclined slide groove is adjustable.

[0013] Preferably, the inclined chute is inclined toward the oil receiving groove; the oil receiving groove is provided with an inclined oil outlet.

[0014] Preferably, the clearance channel has an outwardly extending folded edge; the oil receiving groove overlaps above the folded edge.

[0015] Preferably, one end of the inclined chute is connected to the oil receiving groove, and the other end is connected to the cover plate.

[0016] Preferably, the rotating disk is divided into an inner ring and an outer ring. The inner ring has a number of radially outwardly radiating ribs evenly distributed around its circumference, and the ends of the ribs are inclined at a certain angle to the radial direction. The scraper assembly is located at the outer ring.

[0017] Preferably, the rotating disk is divided into an inner ring and an outer ring. The outer ring has several radially outwardly radiating grooves evenly distributed around its circumference, and the radial width of the outer ring is equal to the depth of immersion in the liquid.

[0018] Preferably, the scraper is disposed on the inner ring side, and the inclined groove extends towards the inner ring side.

[0019] The present invention also aims to provide an oil-water separation device, including an oil-water separation body, and the oil-water separation device further includes the aforementioned automatic oil removal mechanism. The oil-water separation body includes a liquid storage tank, an oil collection tank, and a liquid return tank; the automatic oil removal mechanism is disposed above the liquid storage tank.

[0020] Preferably, the clearance channel of the automatic oil removal mechanism is installed above the liquid storage tank; the inclined oil outlet of the oil receiving tank is located above the oil collecting tank.

[0021] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0022] 1. Floating oil is carried out by the rotating disc of the automatic oil removal mechanism, scraped off by a scraper, and then guided into the oil receiving tank by an inclined chute, which enhances the ability to clean floating oil on the liquid surface. It has a high degree of automation and requires no manual intervention.

[0023] 2. The inner ring of the rotating disc is equipped with raised ribs to guide the floating oil to the outer ring, preventing the floating oil from accumulating on the rotating shaft and the inner ring. The scraper is set on the outer ring to scrape off the most oil.

[0024] 3. A groove is set on the outer ring of the rotating disk. Taking advantage of the different densities of oil and water (water is denser than oil), the water is thrown out through the groove, while the oil remains on the inner ring of the rotating disk. A scraper is set on the inner ring to remove the most oil.

[0025] 4. The automatic oil removal mechanism is an independent module that can be adapted to other oil storage tanks to be removed. When connected to the oil-water separator body, it forms an oil-water separation device for oil skimming. Furthermore, the clearance channel is equipped with a folded edge to prevent oil vapor from overflowing from the joint surface and oil stains from adhering to the equipment surface when the oil is heated.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0036] Example 1:

[0037] like Figure 3As shown, an automatic oil removal mechanism includes a rotating disk 1, a scraper assembly 2, an oil receiving trough 4, and a cover plate 5. The rotating disk 1 has a rotating shaft 12, which passes through the cover plate 5 and is rotatably connected to it. The cover plate 5 is provided with a power source 13 to drive the rotating shaft 12 to rotate. A first transmission wheel is provided on the rotating shaft 12, the power source 13 is provided on the cover plate 5, and a second transmission wheel is provided on the power output shaft. A transmission belt or transmission chain connects the first transmission wheel and the second transmission wheel. The scraper assembly 2 is located on both sides of the rotating disk 1 and abuts against the rotating disk 1. The scraper assembly 2 includes a scraper 20 and a scraper seat 21. The scraper 20 is connected to the scraper seat 21, and the scraper seat 21 is mounted on an inclined slide 3. The position of the scraper seat 21 relative to the inclined slide 3 is adjustable. The inclined slide 3 is provided with a clearance groove 30 for the rotating disk to pass through. The scraper seat 21 is provided with a U-shaped slide groove. By adjusting the position of the scraper seat 21, the scraper 20 can be moved closer to or further away from the rotating disk 1, so that the scraper 20 and the rotating disk 1 maintain a suitable friction gap. Figure 5 The scraper 20 is height-adjustable relative to the scraper seat 21, and the scrapers 20 located on both sides of the rotating disk 1 have different heights; the scraper assembly is installed above the oil receiving groove 4, and the oil receiving groove 4 is provided with an inclined oil outlet 40. The inclined slide 3 is set separately from the oil receiving groove 4, and the inclined slide 3 is located above the oil receiving groove 4. Figure 8 The scraper seat 21 can be directly connected to the oil receiving groove 4. The scraper seat 21 is connected to the oil receiving groove 4, and the oil receiving groove 4 is tilted outward so that the scraped oil flows out through the outer groove of the oil receiving groove 4.

[0038] like Figure 2 , Figure 3 As shown, the bottom of the cover plate 5 is provided with a clearance channel 50, and the rotating disks 1 are all set in the clearance channel 50. The clearance channel 50 is provided with outwardly extending flanges 51 around its perimeter; as shown Figure 3 The oil receiving groove 4 overlaps above the folded edge 51 and is fixed to the cover plate 5. One end of the inclined slide 3 is connected to the oil receiving groove 4, and the other end is connected to the cover plate 5.

[0039] The rotating disk 1 is made of thin steel plate that is oleophilic and hydrophobic, while the scraper 20 is made of rubber. The scraper 20 has a lower hardness than the rotating disk 1, and the scraper seat 21 is adjustable relative to the inclined slide 3. This allows for adjustment of the contact gap between the scraper 20 and the rotating disk 1, preventing rigid contact and excessive friction that could cause scraper wear. The scrapers 20 on both sides of the rotating disk 1 are at different heights to prevent excessive clamping force on the rotating disk 1, which could cause it to jam.

[0040] like Figure 1 , Figure 2 The automatic oil removal mechanism 100 can be installed above the liquid surface to be oiled, directly connected to the top of the oil storage tank. The automatic oil removal mechanism 100 is a standalone module, adaptable to other equipment.

[0041] How the automatic oil removal mechanism works:

[0042] When a thick layer of oil accumulates above the storage tank to be degreased, the automatic degreasing mechanism is activated. The rotating disk 1 rotates slowly under the action of the power 13, adsorbing the floating oil on the surface of the storage tank onto the surface of the rotating disk 1. The scraper 20 scrapes off the floating oil on the surface of the rotating disk 1. The scraped oil slides down through the inclined chute 3 and flows into the oil receiving tank 4, and then flows out through the inclined oil outlet 40 of the oil receiving tank 4.

[0043] Example 2:

[0044] like Figure 1 , Figure 2 , Figure 4 , Figure 5 An automatic oil removal mechanism 100 is installed above an oil-water separator body 200. The oil-water separator body 200 includes a storage tank 201, an oil collection tank 203, and a return tank 204. A partition 202 is installed inside the storage tank, and an inlet pipe 206 is located at the bottom of the storage tank 201. The oil-water separator body 200 also includes a pre-filter 205. A clearance channel 50 of the automatic oil removal mechanism is installed above the storage tank 201, and the inclined oil outlet 40 of the oil collection tank 4 is located above the oil collection tank 203. The clearance channel 50 has outwardly extending flanges 51 around its perimeter. These flanges 51 cover the joint between the storage tank 201 and the cover plate 5, preventing oil vapor from escaping from the joint after heating and causing floating oil to adhere to the equipment surface.

[0045] The oil-liquid mixture is absorbed from the outside and first filtered by the pre-filter 205 before entering the storage tank 201 through the inlet pipe 206. It is then allowed to settle and be deflected by the baffle 202, causing the floating oil to rise and the oil to separate into layers. When a significant amount of floating oil accumulates in the storage tank 201, the automatic oil removal mechanism 100 is activated. This mechanism uses a rotating disc 1 to carry the floating oil from the surface of the storage tank 201 out, and then scrapes it off with a scraper 20. The floating oil first flows through the inclined chute 3 into the oil receiving tank 4, and then from the inclined outlet 40 of the oil receiving tank 4 into the oil collecting tank 203. The clean liquid at the bottom of the storage tank is then led to the return tank 204 through the outlet pipe.

[0046] Example 3:

[0047] like Figure 6 The rotating disk 1 is divided into an inner ring and an outer ring. The inner ring has several radially radiating ribs 10 evenly distributed around its circumference. The ends of the ribs 10 are inclined at a certain angle to the radial direction, opposite to the direction of rotation. A scraper 20 is located on the outer ring. The ribs 10 allow oil on the liquid surface to be thrown outwards along the area between the ribs, ensuring that the oil adheres as much as possible to the outer ring and preventing oil accumulation on the shaft and inner ring. The scraper 20 can also remove the most oil.

[0048] Example 4:

[0049] like Figure 7 The rotating disk 1 is divided into an inner ring and an outer ring. Several grooves 11 are evenly distributed outwards on the circumference of the outer ring, and the radial width of the outer ring is equal to the depth of immersion in the liquid. Due to the density difference between oil and water (oil has a lower density than water has a higher density), water is thrown out along the grooves, while oil is adsorbed on the rotating disk near the inner ring side. A scraper 20 is located on the inner ring side, and an inclined chute 3 extends towards the inner ring side. The grooves 11 on the outer ring facilitate oil-water separation on the rotating disk surface, resulting in less liquid entering the oil receiving tank 4.

Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
