Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, specifically to a self-adjusting floating oil suction device. Background Technology

[0002] In automotive painting processes, pretreatment is a critical production line, among which the degreasing process is particularly important.

[0003] During the degreasing process, when removing oil stains from the surface of the workpiece, floating oil will be generated on the surface of the degreasing liquid, and the content of floating oil has a significant impact on the coating quality of the workpiece.

[0004] Therefore, specialized equipment is needed to collect the floating oil on the liquid surface and transport it to an oil-water separator. However, the liquid level in the degreasing tank fluctuates greatly, and traditional floating oil collection devices cannot be flexibly adjusted to change the liquid level, making it difficult to achieve effective oil removal. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a self-adjusting floating oil suction device with a reasonable structural design, convenient operation, and especially the ability to float up and down with changes in liquid level, thereby improving the oil removal effect and efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A self-adjusting floating oil suction device includes an oil collector, two floats are symmetrically arranged on both sides of the oil collector, and a height adjustment mechanism is provided between the oil collector and each float for adjusting the height between the oil collector and the float. A connecting rod is fixedly installed on the side of the two floats that are far apart from each other, and the ends of the two connecting rods that are opposite to each other are vertically slidably connected to the float slide rails. The float slide rails are detachably connected to the inner wall of the degreasing tank.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] The height adjustment structure includes a first angle steel that is vertically fixedly installed on the top of the pontoon. A mounting hole is opened through one side wall of the first angle steel. A second angle steel is vertically fixedly installed on the top of the oil collector. A long hole is opened through one side wall of the second angle steel, and the long hole is arranged along its height direction. A fastening bolt is inserted into the mounting hole. The free end of the fastening bolt passes through the long hole and is threaded with a fastening nut.

[0010] Further optimization: The oil collector has a hollow box structure, and an inlet is provided on one side.

[0011] Further optimization: The bottom of the oil collector is bent in shape, and the bottom of the oil collector includes a slope extending downward from the inlet end, and the end of the slope is bent to form a flat plane.

[0012] Further optimization: The bottom of the oil collector is fixedly connected to an oil drain pipe at its planar position, and the oil drain pipe is connected to an external oil draining device.

[0013] Further optimization: The floating box has a hollow, closed structure.

[0014] Further optimization: The overall structure of the float box is a right trapezoid, and the hypotenuses of the two float boxes are symmetrically arranged on both sides in front of the oil collector inlet, and the hypotenuses of the two float boxes are arranged in a figure-eight shape.

[0015] Further optimization: The floating box slide rail is symmetrically provided with connection holes near its two ends.

[0016] Further optimization: The cross-section of the pontoon slide rail is concave, and the connecting rod is slidably disposed inside the pontoon slide rail.

[0017] Further optimization: The two ends of the elongated hole are arc-shaped.

[0018] This invention, through the setting of a height adjustment structure, allows for flexible adjustment of the height of the oil collector relative to the float box according to actual needs. This enables operators to determine the initial oil suction height of the oil collector as needed, adapting to changes in oil layer depth at different stages of the degreasing tank, improving oil suction efficiency, and enhancing the oil removal efficiency of coating production. Furthermore, it can rise and fall with the liquid level during oil suction, ensuring that it is always at a suitable oil suction depth, avoiding interruption or poor oil suction effect.

[0019] In this invention, the pontoon is slidably connected to the pontoon slide rail via a connecting rod, and the pontoon slide rail is detachably connected to the inner wall of the degreasing tank, thereby limiting the horizontal displacement of the pontoon and making it float stably. Even with interference such as water flow, it can float stably and provide stable support for the oil collector.

[0020] This utility model is assembled using conventional small parts, which is simple and convenient to assemble, and the parts are common and have low manufacturing costs.

[0021] By adopting the above technical solution, the present invention has a reasonable structural design and is easy to operate. In particular, it can float up and down with changes in the liquid level, thereby improving the oil removal effect and efficiency.

Detailed Implementation

[0030] 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.

[0031] like Figure 1-5 As shown, a self-adjusting floating oil suction device includes an oil collector 1, two float boxes 2 are symmetrically arranged on both sides of the oil collector 1, and a height adjustment mechanism 3 is provided between the oil collector 1 and each float box 2 for adjusting the height between the oil collector 1 and the float box 2. A connecting rod 4 is fixedly installed on the side of the two float boxes 2 that is far away from each other. The ends of the two connecting rods 4 that are opposite to each other are vertically slidably connected to the float box slide rail 5. The float box slide rail 5 is detachably connected to the inner wall of the degreasing tank.

[0032] The height adjustment structure includes a first angle steel 31 vertically fixedly installed on the top of the float 2. A mounting hole 32 is provided through one side wall of the first angle steel 31. A second angle steel 33 is vertically fixedly installed on the top of the oil collector 1. An elongated hole 34 is provided through one side wall of the second angle steel 33, and the elongated hole 34 is arranged along its height direction. A fastening bolt 35 is inserted into the mounting hole 32. The free end of the fastening bolt 35 passes through the elongated hole 34 and is threadedly connected to a fastening nut 36.

[0033] In use, first, place the two floats 2 symmetrically on both sides of the oil collector 1, and then assemble the first angle steel 31 fixedly installed on the top of the floats 2 with the second angle steel 33 fixedly installed on the top of the oil collector 1.

[0034] Subsequently, the operator passes the fastening bolt 35 through the mounting hole 32 of the first angle steel 31 and the elongated hole 34 on the second angle steel 33, and then screws on the fastening nut 36. However, it should not be fully tightened at this time so that the height can be adjusted flexibly later.

[0035] Subsequently, the float rail 5 is installed on the inner wall of the degreasing tank to ensure that the entire device can be stably placed in the corresponding position of the degreasing tank.

[0036] Subsequently, based on the actual usage environment and the depth of the oil layer that needs to be sucked, the position of the oil collector 1 relative to the float box 2 is moved up and down to place the oil collector 1 at a suitable initial height position. Then, the fastening nut 36 is tightened to fix the entire height adjustment mechanism 3, ensuring that the oil collector 1 and the float box 2 maintain the set relative height relationship.

[0037] As the oil suction operation proceeds, when the liquid level in the degreasing tank changes (such as the liquid level rising or falling), the float box 2 will rise or fall accordingly due to buoyancy. At the same time, since the float box 2 and the oil collector 1 are connected by the height adjustment mechanism 3, the up and down movement of the float box 2 will drive the oil collector 1 to move up and down synchronously. The oil collector 1 can always maintain a relatively suitable depth position to carry out the oil suction operation, ensuring that it can effectively suck up grease and other impurities on the liquid surface.

[0038] This design allows for several advantages. First, the height of the oil collector 1 relative to the float box 2 can be flexibly adjusted according to actual conditions through the height adjustment structure. This enables operators to determine the initial oil suction height of the oil collector 1 as needed, adapting to changes in oil layer depth at different stages of the degreasing tank, improving oil suction efficiency, and enhancing the oil removal efficiency in coating production. Furthermore, the oil collector 1 can rise and fall with the liquid level during oil suction, ensuring that it is always at a suitable oil suction depth and avoiding interruptions or poor results in oil suction.

[0039] Secondly, the float box 2 is slidably connected to the float box slide rail 5 via the connecting rod 4. The float box slide rail 5 is detachably connected to the inner wall of the degreasing tank, thereby limiting the horizontal displacement of the float box 2 and making it float stably. Even if there is interference such as water flow, it can float stably and provide stable support for the oil collector 1.

[0040] Furthermore, the device is assembled from common small parts, making assembly simple and convenient, and the parts are readily available and have low manufacturing costs.

[0041] The oil collector 1 has a hollow box structure, and an inlet 11 is provided on one side.

[0042] The bottom of the oil collector 1 is bent in an overall shape. The bottom of the oil collector 1 includes an inclined surface 12 that extends downward from the liquid inlet 11 and a flat surface 13 formed by bending at the end of the inclined surface 12.

[0043] This design allows the downward-sloping inclined surface 12 at the inlet 11 to allow the fluid (such as a mixture of oil and water) entering the oil collector 1 to flow more smoothly to the flat surface 13 formed by the bend at the end under the action of gravity, thereby helping to improve the collection efficiency of floating oil.

[0044] In this embodiment, the inclined surface 12 is inclined downward at 20-30 degrees from the liquid inlet 11 end.

[0045] This design, with the tilt angle within this range, ensures the speed of oil flow without causing splashing or other problems due to excessively high oil flow rate caused by an excessively large angle.

[0046] The bottom of the oil collector 1 is fixedly connected to the oil drain pipe 7 at position 13 on its plane, and the oil drain pipe 7 is connected to the external oil draining device.

[0047] This design ensures that the oil collected in oil collector 1 can be discharged quickly and smoothly.

[0048] The pontoon 2 is a hollow, enclosed structure.

[0049] This design, firstly, utilizes the principle of air buoyancy. The hollow interior of the float box 2, containing air, makes the overall density less than that of the liquid, allowing the oil suction device to float stably on the liquid surface and preventing sudden changes caused by liquid intrusion. It also allows the oil collector 1 to maintain a suitable oil suction level in the fluctuating degreasing tank, ensuring the oil suction operation.

[0050] Secondly, it can prevent the degreasing tank liquid from entering, increasing weight, reducing buoyancy, and affecting floating performance. It can also prevent impurities and chemicals in the liquid from corroding the internal structure or damaging internal devices, and can extend service life in degreasing liquid containing corrosive chemicals.

[0051] Furthermore, the structural strength of float 2 has been improved, which can evenly distribute the device's own weight, liquid pressure, and impact force, reducing the risk of local deformation and damage.

[0052] The overall structure of the float box 2 is a right trapezoid. The hypotenuses of the two float boxes 2 are symmetrically arranged on both sides in front of the oil inlet 11 of the oil collector 1, and the hypotenuses of the two float boxes 2 are arranged in a figure-eight shape.

[0053] With this design, firstly, the inclined sides of the two float boxes 2 are located in front of the inlet 11 of the oil collector 1 and are arranged in a figure-eight shape, guiding the oil flow to the inlet 11 of the oil collector 1 and improving the oil collection efficiency.

[0054] Secondly, the shape of the float 2 shifts the center of gravity to the rear, and the inclined side can buffer and resist overturning, improving the anti-overturning safety factor. The more reasonable buoyancy distribution ensures the normal operation of the oil collector 1.

[0055] The floating box slide rail 5 has symmetrical connecting holes 6 near its two ends.

[0056] This design facilitates the stable installation of the float rail 5 on the inner wall of the degreasing tank.

[0057] The cross-section of the float rail 5 is concave, and the connecting rod 4 is slidably disposed inside the float rail 5.

[0058] This design, firstly, allows for conventional manufacturing processes for the concave guide rail and the straight connecting rod 4, making it easy to control machining accuracy, resulting in high production efficiency and low cost.

[0059] Secondly, the components are few and the connections are direct, with only two main components and no extra connecting parts, reducing assembly errors and compatibility issues.

[0060] Finally, it is easy to position and insert. The concave guide rail can guide naturally and is not easy to deviate during insertion, without the need for additional positioning clamps. Moreover, no special installation tools and skills are required. Ordinary workers can use simple hand tools, which lowers the installation threshold.

[0061] The inner diameter of the float rail 5 is 5-10 mm larger than the outer diameter of the connecting rod 4.

[0062] This design, firstly, by making the inner diameter of the float rail 5 larger than the outer diameter of the connecting rod 4 by an appropriate size, effectively reduces the contact area and friction coefficient, reduces energy loss, and improves system efficiency; at the same time, the degree of wear is significantly reduced, thereby extending the service life of the equipment, greatly reducing the frequency of maintenance and component replacement during long-term operation, and thus saving costs.

[0063] Secondly, the inner diameter of the float box slide rail 5 is appropriately larger than the outer diameter of the connecting rod 4, which effectively avoids the situation where the pressure between the two increases sharply or even jams due to the expansion of the material caused by the increase in temperature. It also prevents the stability and accuracy of the equipment from being affected by the excessive gap, thereby ensuring that the equipment can operate normally and stably under different ambient temperature conditions.

[0064] Furthermore, the inner diameter of the float rail 5 is appropriately larger than the outer diameter of the connecting rod 4, which facilitates the insertion of the connecting rod 4 into the float rail 5, thereby effectively reducing the installation difficulty and precision requirements, improving installation efficiency, and saving installation time and costs.

[0065] The two ends of the elongated hole 34 are arc-shaped.

[0066] This design ensures that when the fastening bolt 35 is subjected to external forces (such as vibration, forces generated by thermal expansion and contraction of components) within the elongated hole 34, the two ends of the arc shape can effectively avoid stress concentration, allowing the stress to be distributed more evenly along the edge of the arc shape, thus reducing the risk of fatigue, cracking, or bolt damage to the hole wall material due to stress concentration.

[0067] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
