Obviously, the embodiments described in the present application are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0019] See also Figures 1 to 4 To further illustrate the present application, a vertical strip degreasing device includes a frame 1 and a guide roller assembly 4. A cleaning chamber 10 is provided in the frame 1. The guide roller assembly 4 is provided in the cleaning chamber 10 for guiding the strip 7.

[0021] Combination Figure 3Specifically, the sealing structure 5 is respectively arranged on the outer sides of the baffle plate 2 and the frame 1; the sealing structure 5 is arranged on the outer sides of the baffle plate 2 and the frame 1, and the partition layer 3 can separate the degreasing tank 20 from the frame 1, and the structure can combine leak plugging; under normal conditions, the sealing structure 5 can prevent the degreasing liquid from leaking; when the sealing structure 5 is worn, the degreasing liquid leaks out of the sealing structure 5 on the baffle plate 2 and enters the partition layer 3, and the degreasing liquid leaked therein is discharged through the drain pipe 40A, which will not cause the degreasing liquid to leak out of the frame and affect the normal use of the device, thereby avoiding the degreasing liquid from leaking out of the frame 1 to pollute the environment.
[0022] Combination Figure 4 The tension roller 42 and the immersion roller 41 are both rotatably connected to the sealing structure 5. The sealing structure 5 includes a waterproof layer 1 51, a waterproof layer 2 52 and a sealing member 53 from the inside to the outside. The waterproof layer 1 51, the waterproof layer 2 52 and the frame are detachably connected to facilitate disassembly and maintenance. The sealing structure 5 can support the rotation of the immersion roller 41 or the tension roller 42, and can seal it to prevent the degreasing liquid from leaking out of the frame 1 along the immersion roller 41 and the tension roller 42, causing corrosion of the device and pollution of the environment.
[0023] Combination Figure 4 The submerged roller 41 and the tension roller 42 are rotatably connected to the corresponding second waterproof layer 52. The sealing member 53 is sleeved on the submerged roller 41 or the tension roller 42 and is located outside the second waterproof layer 52, and is used to seal between the submerged roller 41 or the tension roller 42 and the second waterproof layer 52. In this embodiment, the sealing member 53 is a sealing ring. When leakage occurs, only the second waterproof layer 52 needs to be replaced, and the sealing structure 5 does not need to be replaced as a whole, so as to reduce maintenance costs.
[0024] Among them, combined Figure 4 , the sealing structure 5 on the outer frame 1 is used as an example for explanation; the waterproof layer 1 51 and the waterproof layer 2 52 both include a sealing pad and a waterproof board, the sealing pad plays a sealing role, the waterproof board plays a supporting and reinforcing role, and has a water-blocking effect; the waterproof layer 1 51 is arranged between the frame and the waterproof layer 2 52, and the waterproof layer 2 52 is used to support the rotation of the immersion roller and the tensioning roller to prevent the degreasing liquid from leaking. When the waterproof layer 2 is made of polytetrafluoroethylene, the friction coefficient is low, which can effectively reduce the wear and replacement frequency of the waterproof layer 2 52.
[0025] Combination Figure 2The frame 1 is provided with a water inlet 8 connected to the degreasing tank 20 for adding degreasing liquid into the degreasing tank 20. During operation, the degreasing liquid in the liquid storage tank can be continuously replenished into the degreasing tank 20 through the water inlet 8 by a pump.
[0026] An overflow port 9 is provided in the degreasing tank 20, and the overflow port 9 is lower than the top of the baffle 2. The overflow port 9 is connected to the drain pipe three 40C. The grease washed off the strip 7 will float on the surface of the degreasing liquid. By continuously replenishing the degreasing liquid into the degreasing tank 20, the grease floating on the degreasing liquid will enter the overflow port and overflow back into the liquid storage tank through the drain pipe three 40C to ensure that the degreasing liquid does not overflow the baffle 2, avoid excessive grease floating on the surface of the degreasing liquid and re-adhere to the surface of the strip 7 after cleaning, and at the same time ensure that the degreasing liquid in the degreasing tank 20 is at the optimal degreasing temperature to improve the degreasing effect, and the degreasing liquid can be recycled to avoid waste.
[0027] Combination Figure 3 A plurality of water return grooves 30 are provided on the outer sides of the baffle plate 2 and the frame 1, and the water return grooves 30 are provided below the sealing structure 5 to receive the degreasing liquid leaking out of the sealing structure 5; the water return grooves 30 are provided with drainage holes, and the degreasing liquid leaking in the water return grooves 30 above will flow into the water return grooves 30 below through the drainage holes in sequence, and finally gather in the water return grooves 30 at the bottom, wherein the water return grooves 30 can be arranged at an angle to facilitate the degreasing liquid in the water return grooves 30 to gather to one side and flow to the bottom from the drainage holes.
[0028] Combination Figure 3 In this embodiment, the degreasing liquid in the return water groove 30 outside the baffle 2 will be collected at the bottom of the partition 3; the degreasing liquid in the return water groove 30 outside the frame 1 flows into the return water groove 30 at the bottom through the drainage hole; a drainage pipe 2 40B is provided on the return water groove 30 at the bottom of the outermost side of the frame 1, and the drainage pipe 2 40B is connected to the drainage hole on the return water groove 30, and the drainage pipe 1 40A, the drainage pipe 2 40B and the drainage pipe 3 40C are all connected to the liquid storage tank; the remaining drainage holes can be connected to a hose to drain the degreasing liquid to the return water groove 30 below to prevent the degreasing liquid from splashing.
[0029] When the sealing structure 5 on the outside of the frame 1 also wears, the leaked degreasing liquid first flows back to the liquid storage tank through the drain pipe 1 40A, and a small amount of degreasing liquid may leak into the return water tank 30 on the outside of the frame 1. Then, the degreasing liquid leaked from the return water tank 30 on the outside of the frame 1 can be returned to the liquid storage tank through the drain pipe 2 40B, and the leaked degreasing liquid can be recovered for recycling, thereby reducing waste and avoiding environmental pollution.
[0030] The frame 1 is provided with a water outlet 50 connected to the degreasing tank 20, and the bottom of the cleaning chamber 10 is inclined to facilitate the discharge of the degreasing liquid in the degreasing tank 20, and the degreasing liquid in the degreasing tank 20 can be discharged well.
[0031] Strip degreasing is a part of the strip production line. In the prior art, the immersion roller 41 and the tensioning roller 42 are rotatably connected to the frame 1. Long-term operation causes wear between them and the frame 1, which easily leads to leakage of degreasing liquid. The degreasing liquid leaks to the outside of the frame 1 and causes pollution, which requires maintenance and affects production efficiency. The baffle plate and the frame of the present application form a double-layer structure, and the degreasing liquid is placed in the degreasing tank 20 between the baffle plates 2. When the sealing structure 5 is worn, the degreasing liquid will leak into the partition 3 and flow back to the liquid storage tank through the drain pipe 40A in the partition 3. It is difficult for the degreasing liquid to leak to the outside of the frame 1 to pollute the environment. At the same time, the leaked degreasing liquid can be recycled to avoid waste, so that the device can still work normally in a leaking state.
[0032] The drain pipe 1 40A, the drain pipe 2 40B and the drain pipe 3 40C are also provided with a filter assembly (not shown), and the filter assembly is used to filter the degreasing liquid therein to prevent impurities in the degreasing liquid from entering the liquid storage tank.
[0033] Combination Figure 2 The deflection roller 43 is located at the upper side of the cleaning chamber 10, and is used to guide the strip 7 into or out of the cleaning chamber 10. The immersion roller 41 is located at the bottom of the degreasing tank 20, and is used to guide the strip 7 into the degreasing liquid. The strip 7 enters and exits the cleaning chamber 10 through the following path: it enters the cleaning chamber from the deflection roller 43 on one side, passes downward through at least one tensioning roller 42 and the immersion roller 41 to the bottom of the cleaning chamber 10, changes direction, and passes upward through the tensioning roller 42 and the deflection roller 43 to the top of the cleaning chamber 10; the path can be repeated at least once, and finally passes through the deflection roller 43 from the cleaning chamber 10. The cleaning chamber is led out; the tensioning wheel is arranged between the deflection roller 43 and the immersion roller 41; when the number of the immersion rollers 41 is N, the number of the deflection rollers 43 is N+1, and the number of the tensioning rollers 42 in each layer is N+2. In this embodiment, the immersion rollers 41 are 2, the deflection rollers 43 are 3, the tensioning rollers 42 are two layers, and the tensioning rollers 42 in each layer are 4. The tensioning rollers 42 are respectively abutted against both sides of the strip 7 for tensioning the strip 7. Under the premise of ensuring the cleaning length of the strip 7, the floor area can be greatly reduced and the occupied space can be reduced.
