Technical Field
[0001] This utility model relates to the field of cold rolling mill technology, specifically to a device for preventing oil spillage in a mixing tank. Background Technology
[0002] The oil spill prevention device for the mixing drum of a cold rolling mill is a key auxiliary device for ensuring the safety of cold rolling production. It is specifically designed to solve the problem of lubricating oil / hydraulic oil overflow from the mixing drum. Its core consists of a level sensor, an automatic control valve, an audible and visual alarm system, and a flow guiding component. Installed on the top of the mixing drum and at the oil outlet pipeline, the sensor monitors the oil level in the drum in real time during operation. Once the level approaches the preset safety threshold, the system immediately triggers dual protection: automatically closing the oil inlet valve to cut off the supply, and simultaneously activating the audible and visual alarm to alert the operator. The flow guiding component quickly guides a small amount of overflowing oil back to the oil storage chamber, preventing contamination of equipment or the ground. This device responds rapidly and provides precise protection, reducing oil waste and mitigating safety risks such as fire and equipment corrosion. It also significantly reduces the intensity of manual inspections, providing reliable assurance for the continuity and safety of cold rolling production.
[0003] Diatomaceous earth and cellulose are added to the mixing tank and pumped to the platen for filtering of rolling oil. The liquid level in the mixing tank is controlled by a float level gauge. The diatomaceous earth and cellulose in the mixing tank have a certain degree of adhesion, and the float of the level gauge often gets stuck, causing the level gauge to fail to control the liquid level properly. This can easily lead to oil overflow in the mixing tank. Oil overflow in the mixing tank increases product oil consumption and manufacturing costs. Oil overflow in the mixing tank requires absorption and cleaning, which increases hazardous waste costs. If the oil overflow in the mixing tank flows into the sewer and into the river, it will have a serious impact on the environment. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an oil spill prevention device for a mixing tank, which can effectively solve the problem of oil spill in the mixing tank in the prior art, save rolling oil, and prevent the environmental pollution caused by rolling oil leakage.
[0005] The technical solution adopted by this utility model is: an oil spill prevention device for a mixing tank, comprising a mixing tank body and an oil inlet assembly, wherein a mixing assembly, a level gauge and an oil suction assembly are fixedly installed on one end of the mixing tank body near the oil inlet assembly, and a support assembly and an oil spill prevention assembly are fixedly installed on the outer wall of the mixing tank body; the oil inlet assembly includes an oil inlet pipe and a pneumatic pump, wherein a pneumatic pump is fixedly installed on one end of the oil inlet pipe away from the mixing tank body.
[0006] Preferably, the anti-overflow component includes an overflow pipe and a flow meter. The flow meter is fixedly installed at the end of the overflow pipe away from the mixing tank body. The overflow pipe is located 5cm below the highest liquid level. The mixing tank body, the overflow pipe, and the flow meter are connected.
[0007] With the above technical solution, when the rolling oil level is too high, the rolling oil will flow out from the overflow pipe and into the interior of the rolling mill. When the flow meter detects flow, the oil inlet component will stop adding oil to the mixing tank body to prevent oil from overflowing into the mixing tank body, so that the mixing process can be carried out continuously and stably, reducing production delays caused by sudden situations, while avoiding rolling oil overflowing into the sewer, causing pollution of sewer pipes and rivers, and saving costs.
[0008] Preferably, the support assembly includes a fixed frame, a fixed seat is fixedly installed on the outer wall of the fixed frame, a lead screw is rotatably installed on the inner wall of the fixed seat, a sliding groove is formed on the inner wall of the fixed seat, a connecting block is fixedly installed on the outer wall of the lead screw, a handle is fixedly installed on the end of the lead screw near the fixed frame, a slider and a connecting frame are fixedly installed on the outer wall of the connecting block, a reinforcing rod, a first insert block and a second insert block are fixedly installed on the end of the connecting frame away from the connecting block, a through hole is formed on the outer wall of the second insert block, a support plate is provided on the end of the connecting frame away from the connecting block, a slot first, a slot second and a through hole second are formed on the end of the support plate near the fixed frame, a screw is inserted into the end of the support plate near the fixed frame, a nut is threaded onto the outer wall of the screw, and the slider and the sliding groove are slidably connected.
[0009] With the above technical solution, the worker can rotate the lead screw by turning the handle. The rotation of the lead screw drives the connecting block to move, and at the same time, it drives the slider to slide inside the slide groove. The movement of the connecting block drives the connecting frame to move, thereby driving the support plate to move.
[0010] Preferably, the support plate has a "C" shaped cross-section and is adapted to the oil absorption assembly.
[0011] With the above technical solution, when the support plate comes into contact with the oil absorption component, the support plate can support the oil absorption component, thereby improving the overall stability. The support plate has a "C" shaped cross-section, which can form a wrap-around fit with the outer wall of the oil absorption component. Compared with planar support, this increases the contact area and friction, effectively limiting the horizontal displacement of the oil absorption component.
[0012] Preferably, the cross-section of the reinforcing rod is "X" shaped, and the cross-section of the reinforcing rod combined with the connecting frame is "triangular".
[0013] Through the above technical solution, the design of the reinforcing rod, due to the stability of the triangle, makes the force system of the support component more stable, and evenly transmits the weight of the oil suction component and the working load from the support plate to the fixed frame, thereby increasing the load-bearing capacity of the entire support structure and extending the service life of the device.
[0014] Preferably, the first plug and the first slot are plugged in and installed together, and the second plug and the second slot are plugged in and installed together.
[0015] Using the above technical solution, the worker inserts the first insert into the first slot and the second insert into the second slot, which enables the support plate to be quickly positioned without complicated alignment steps, thus improving assembly efficiency.
[0016] Preferably, the screw passes through both through hole two and through hole one, and the diameters of through hole two and through hole one are the same.
[0017] Using the above technical solution, after the support plate is quickly positioned, the workers insert the screw through the second through hole and the first through hole, and then connect the nut to the screw thread. This allows for quick positioning of the support plate. After long-term use, it is easy to inspect or replace it. At the same time, when it is necessary to support oil pipes of different diameters, only the support plate that is compatible with it needs to be replaced, which has high adaptability.
[0018] Compared with the prior art, the present invention provides a device for preventing oil spillage in a mixing tank, which has the following beneficial effects: 1. This overflow prevention device for mixing tanks, through the design of the overflow prevention component, when the rolling oil level is too high, the rolling oil will flow out from the overflow pipe and into the interior of the rolling mill. When the flow meter detects flow, the oil inlet component will stop adding oil to the mixing tank body to prevent the mixing tank body from overflowing, so that the mixing process can be carried out continuously and stably, reducing production delays caused by sudden situations, while avoiding rolling oil overflowing into the sewer, causing pollution of sewer pipes and rivers, and saving costs; 2. This oil spill prevention device for mixing tanks features a support component design that supports the oil suction component, improving overall stability. The "C"-shaped cross-section of the support plate creates a wraparound fit with the outer wall of the oil suction component, increasing the contact area and friction compared to planar support. This effectively limits the horizontal displacement of the oil suction component. The reinforcing rod design, with its triangular shape providing stability, further stabilizes the force system of the support component, evenly distributing the weight of the oil suction component and the operating load from the support plate to the fixed frame. This increases the load-bearing capacity of the entire support structure and extends the device's service life. The quick positioning of the support plate is achieved through the cooperation of insert one with slot one, insert two with slot two, screw, through hole two, and through hole one with nut. This facilitates maintenance or replacement after prolonged use. Furthermore, when supporting oil pipes of different diameters is required, only the appropriate support plate needs to be replaced, demonstrating high adaptability. Attached Figure Description

[0021] 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.
[0022] Example 1: like Figure 1-7 As shown, the present invention provides an oil spill prevention device for a mixing tank, comprising a mixing tank body 1 and an oil inlet assembly 2. A mixing assembly 3, a level gauge 4 and an oil suction assembly 5 are fixedly installed on one end of the mixing tank body 1 near the oil inlet assembly 2. A support assembly 6 and an anti-overflow assembly 7 are fixedly installed on the outer wall of the mixing tank body 1. The oil inlet assembly 2 includes an oil inlet pipe 201 and a pneumatic pump 202. The pneumatic pump 202 is fixedly installed on the end of the oil inlet pipe 201 away from the mixing tank body 1.
[0023] Specifically, the anti-overflow component 7 includes an overflow pipe 701 and a flow meter 702. The flow meter 702 is fixedly installed at the end of the overflow pipe 701 away from the mixing tank body 1. The overflow pipe 701 is located 5cm below the highest liquid level. The mixing tank body 1, the overflow pipe 701, and the flow meter 702 are connected. The advantage is that when the rolling oil level is too high, the rolling oil will flow out from the overflow pipe 701 and into the interior of the rolling mill. When the flow meter 702 detects flow, the oil inlet component 2 will stop adding oil to the mixing tank body 1, preventing oil overflow from the mixing tank body 1. This allows the mixing process to proceed continuously and stably, reducing production delays caused by unexpected situations. It also prevents rolling oil from overflowing into the sewer, causing pollution to sewer pipes and rivers, and saves costs.
[0024] Specifically, the support component 6 includes a fixed frame 601, a fixed seat 602 fixedly mounted on the outer wall of the fixed frame 601, a lead screw 603 rotatably mounted on the inner wall of the fixed seat 602, a sliding groove 604 formed on the inner wall of the fixed seat 602, a connecting block 605 fixedly mounted on the outer wall of the lead screw 603, a handle 618 fixedly mounted on the end of the lead screw 603 near the fixed frame 601, a slider 606 and a connecting frame 607 fixedly mounted on the outer wall of the connecting block 605, and a fixedly mounted slider 606 and a connecting frame 607 on the end of the connecting frame 607 away from the connecting block 605. The device includes a reinforcing rod 608, a first insert 609, and a second insert 610. The outer wall of the second insert 610 has a through hole 611. A support plate 612 is located at the end of the connecting frame 607 away from the connecting block 605. The end of the support plate 612 near the fixing frame 601 has a slot 613, a second slot 614, and a second through hole 615. A screw 616 is inserted and installed at the end of the support plate 612 near the fixing frame 601. A nut 617 is threaded onto the outer wall of the screw 616. The slider 606 and the slide groove 604 are slidably connected. The advantage is that the operator can rotate the lead screw 603 by using the handle 618. The rotation of the lead screw 603 moves the connecting block 605, simultaneously causing the slider 606 to slide inside the slide groove 604. The movement of the connecting block 605 moves the connecting frame 607, thereby moving the support plate 612.
[0025] Specifically, the support plate 612 has a C-shaped cross-section and is adapted to the oil-absorbing assembly 5. The advantage is that when the support plate 612 contacts the oil-absorbing assembly 5, it supports the assembly, improving overall stability. The C-shaped cross-section of the support plate 612 allows for a wraparound fit with the outer wall of the oil-absorbing assembly 5, increasing the contact area and friction compared to planar support, effectively limiting the horizontal displacement of the oil-absorbing assembly 5.
[0026] Example 2: like Figure 2-7As shown, as an improvement on the previous embodiment, to further enhance the overall load-bearing capacity, specifically, the cross-section of the reinforcing rod 608 is an "X" shape, and the cross-section of the reinforcing rod 608 combined with the connecting frame 607 is a "triangular" shape. The advantage is that, through the design of the reinforcing rod 608, the stability of the triangle shape makes the force-bearing system of the support assembly 6 more stable, evenly transmitting the weight of the oil-absorbing assembly 5 and the working load from the support plate 612 to the fixed frame 601, increasing the upper limit of the load-bearing capacity of the entire support structure and extending the service life of the device.
[0027] Specifically, insert block 609 and slot 613 are connected by a plug-in joint, and insert block 610 and slot 614 are also connected by a plug-in joint. The advantage is that when the operator inserts insert block 609 into slot 613 and inserts insert block 610 into slot 614, the support plate 612 can be quickly positioned without complicated alignment steps, thus improving assembly efficiency.
[0028] Specifically, the screw 616 passes through through hole two 615 and through hole one 611, with the same diameter as through hole two 615 and through hole one 611. The advantage is that after quickly positioning the support plate 612, the operator can pass the screw 616 through through hole two 615 and through hole one 611, and then thread the nut 617 onto the screw 616, achieving quick positioning of the support plate 612. This facilitates maintenance or replacement after prolonged use. Furthermore, when supporting oil pipes of different diameters is required, only a compatible support plate 612 needs to be replaced, demonstrating high adaptability.
[0029] Working principle: During installation, the operator inserts plug 609 into slot 613 and plug 610 into slot 614, achieving rapid positioning of the support plate 612 without complex alignment steps, thus improving assembly efficiency. After quickly positioning the support plate 612, the operator inserts screw 616 through through hole 615 and through hole 611, and then threads nut 617 onto screw 616, achieving rapid positioning of the support plate 612. This facilitates adjustment after prolonged use. For maintenance or replacement, when supporting oil pipes of different diameters is required, simply replace the support plate 612 with a suitable one, demonstrating high adaptability. During use, the operator rotates the screw 603 via handle 618. The screw 603's rotation moves the connecting block 605, simultaneously causing the slider 606 to slide within the groove 604. The movement of the connecting block 605 moves the connecting frame 607, thereby moving the support plate 612. When the support plate 612 contacts the oil suction assembly 5, the support plate... Support plate 612 supports oil suction component 5, improving overall stability. The "C"-shaped cross-section of support plate 612 allows for a wraparound fit with the outer wall of oil suction component 5, increasing contact area and friction compared to planar support, effectively limiting horizontal displacement of oil suction component 5. The reinforcing rod 608, with its triangular stability, further stabilizes the force system of support component 6, evenly transmitting the weight of oil suction component 5 and operating load from support plate 612 to fixed frame 601, increasing the load-bearing capacity of the entire support structure and extending the device's service life. When the rolling oil level is too high, the rolling oil will flow out from overflow pipe 701 into the mill. When flow meter 702 detects flow, oil inlet component 2 will stop adding oil to the mixing tank body 1, preventing oil overflow and ensuring continuous and stable mixing. This reduces production delays caused by unforeseen circumstances, prevents rolling oil from overflowing into sewers and polluting drainage pipes and rivers, and saves costs.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
