Description

Technical Field

[0001] This invention relates to the field of leather deliming technology, and more specifically to an animal leather deliming device. Background Technology

[0002] Deliming is a crucial process in the leather industry. It involves removing alkaline substances (such as lime and sulfides) from the raw hide after liming using chemical or water washing methods, eliminating their swollen state, and lowering the pH value to a suitable range to create conditions for subsequent enzymatic softening and tanning processes. This process removes free, adsorbed, and bound ash and alkali from collagen fibers through neutralization reactions, while also removing impurities such as fatty saponifications. Its effectiveness directly affects the softness and fiber dispersibility of the leather. Traditional deliming mainly uses strong acid-weak base salts such as ammonium sulfate and ammonium chloride to achieve dealkalization by generating ammonia gas, but this can lead to ammonia nitrogen pollution.

[0003] Chinese Patent Publication No. CN108265132A discloses a leather deashing device, comprising a main body, a rotating drum movably mounted in the middle of the main body, a feeding port on the outer surface of the drum, a rotating wheel movably mounted in the middle of the drum, a purifier fixedly mounted on one side of the rotating wheel, an air pump fixedly connected to one end of the purifier, and a power supply cabinet fixedly mounted on one side of the air pump. A control cabinet is fixedly mounted on the outer surface of the main body near the lower end, and a control panel is fixedly mounted on the outer surface of the control cabinet near the upper end. This leather deashing device, equipped with a drying tube, ball bearings, and a reducer, effectively purifies the ammonia gas generated during deashing, reduces pollution, effectively reduces the friction coefficient of the rotating mechanism, improves rotational efficiency, effectively matches the rotational speed, smoothly reduces rotation, extends the equipment's lifespan, and brings better application prospects.

[0004] After the ash-soaking and hair removal process, the ash-covered hides are fed into a rotating drum. Water is injected into the drum and the temperature is adjusted to a suitable level. Then, ammonium sulfate deashing agent is added, and the drum is started to rotate continuously. The ammonium sulfate hydrolyzes and releases hydrogen ions to neutralize the lime in the hides, and calcium sulfate precipitates continuously. However, the device is not equipped with a precipitation and filtration unit. Under the agitation of the rotating drum, impurities such as calcium sulfate precipitate, epidermal debris, hair root residue, and sulfide flocs accumulate in the bath. On the one hand, this hinders the penetration of hydrogen ions into the gaps between collagen fibers, weakening the efficiency of lime neutralization and removal in the hides. On the other hand, the impurities adhere to the bare hide surface and the inside of the fiber bundles, inducing defects such as discoloration on the finished hide surface. Summary of the Invention

The free section is fixedly connected to the transmission gear on the same axis. The outlet section is fixedly connected to the panel.

[0013] Preferably, the water spraying mechanism includes a water wheel, which is coaxially disposed inside the free section, and the outlet section is provided with a nozzle.

[0028] The following will be for reference. Figures 1 to 6 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] An animal leather deliming device, such as Figures 1-3As shown, it includes a roller 1, an outer cylinder 2 on the outside of the roller 1, a processing chamber 3 inside the roller 1, and a conveying mechanism inside the outer cylinder 2 for introducing the bath liquid inside the roller 1 into the processing chamber 3; the output part of the processing chamber 3 is provided with a filtration mechanism, and the output part of the filtration mechanism is provided with a water spraying mechanism. The roller 1 is linked with the water spraying mechanism, and the output end of the water spraying mechanism extends into the tail of the roller 1.

[0030] During the deashing process of this device, impurities (such as calcium sulfate precipitate, epidermal debris, hair root residue, sulfide flocs, etc.) will be generated in the bath liquid. The conveying mechanism continuously introduces the bath liquid in the drum 1 into the treatment chamber 3, and then after being filtered by the filtration mechanism, it is sprayed out from the water spraying mechanism and returned to the inside of the drum 1, realizing the internal circulation purification mechanism of the bath liquid and preventing the accumulation of impurities in the bath liquid in the drum 1 from affecting the deashing effect.

[0031] Several lifting ribs 4 are inclinedly arranged on the inner wall of the roller 1. During the rolling process of the roller 1, the side walls of the lifting ribs 4 support the leather and rely on frictional traction to overcome the leather's own weight and liquid viscosity resistance, carrying the leather away from the bath liquid surface and lifting it up. After rising to a certain height, the leather falls down under the action of gravity. During the rotation of the roller 1, the leather inside continues to rise and fall freely, forming a repeated slapping and kneading action, which effectively destroys the gray structure of the leather surface, accelerates the dissolution rate of alkaline ash inside the leather, and improves the efficiency of the deashing operation. It should be noted that in this embodiment, the lifting ribs 4 inclinedly arranged inside the roller 1 of this device can push the leather towards the tail of the roller 1 when the lifting ribs 4 support the leather and lift it up, so that the landing point of the leather is always close to the spray area of ​​the water spraying mechanism, ensuring that the high-pressure rinsing water flow can act on the leather material and ensure the rinsing and deashing treatment effect.

[0032] like Figure 2 and Figure 3 As shown, the outer cylinder 2 has a partition 5 inside, which divides the space inside the outer cylinder 2 into a head chamber and a tail chamber. The roller 1 is coaxially arranged inside the head chamber. The chamber between the outer wall of the roller 1 and the inner wall of the outer cylinder 2 is a conveying channel 9. The conveying mechanism includes a spiral blade 6 on the outer wall of the roller 1 and an annular connecting part 7 on the outer cylinder 2. The annular connecting part 7 is coaxially rotatably connected to the head of the roller 1. The annular connecting part 7 has a first connecting port 8, through which the roller 1 and the conveying channel 9 are fluidly connected. An installation cylinder 10 is rotatably connected to the side of the partition 5 near the tail chamber. A heat exchange plate 11 is coaxially fixedly connected to the installation cylinder 10. The heat exchange plate 11 is made of a material with high thermal conductivity, such as a metal plate. The edge of the heat exchange plate 11 is rotatably connected to the inner wall of the outer cylinder 2. The space between the partition 5 and the heat exchange plate 11 is the processing chamber 3. A second connecting port 13 is started on the partition 5, through which the processing chamber 3 is fluidly connected to the conveying channel 9.

[0033] During the rolling process of the drum 1, the spiral blades 6 are driven to rotate, and the bath liquid in the drum 1 is introduced into the interior of the conveying channel 9 through the first connecting port 8, and then transported to the interior of the processing chamber 3 through the second connecting port 13.

[0034] like Figure 3 As shown, the space on the other side of the heat exchange plate 11 is set as a hot water chamber 12. Both sides of the heat exchange plate 11 are provided with heat-conducting blades 14. In this embodiment, a heating source 35, such as an electric heating wire, is provided in the hot water chamber 12 to heat the water in the hot water chamber 12. The heat in the hot water chamber 12 is transferred to the interior of the processing chamber 3 through the heat exchange plate 11, thereby heating the bath liquid in the processing chamber 3. By setting the heat-conducting blades 14, the heat exchange area can be increased, thereby improving the heating efficiency.

[0035] like Figure 3 As shown, a panel 15 is rotatably connected to the tail of the roller 1, and a partition 5 is fixedly connected to the panel 15. The cavity between the partition 5 and the panel 15 is designated as the installation cavity 18. A motor 16 is installed on the outside of the outer cylinder 2. The motor 16 is a servo motor. The output end of the motor 16 is coaxially inserted into the outer cylinder 2, and a central shaft 17 is coaxially fixedly connected to its end. The central shaft 17 passes through the installation cylinder 10 and the partition 5 in sequence and extends into the interior of the installation cavity 18. A first gear 19 is coaxially fixedly connected to its end. An internal gear ring 20 is provided on the inner wall of the roller 1 inside the installation cavity 18. A transmission gear 21 is rotatably connected on the partition 5 inside the installation cavity 18. The first gear 19 and the internal gear ring 20 are both meshed with the transmission gear 21. When the motor 16 starts, it drives the central shaft 17 to rotate the first gear 19, which in turn drives the transmission gear 21 to rotate the internal gear ring 20, thus causing the roller 1 to roll.

[0036] like Figures 3-6 As shown, the filtration mechanism includes a cylindrical body, which consists of an inlet section 22, a free section 23, and an outlet section 24. The two ends of the free section 23 are rotatably connected to the inlet section 22 and the outlet section 24, respectively. The inlet section 22 is fixedly connected to the partition plate 5 through it. The input part of the inlet section 22 extends into the interior of the processing chamber 3. A filter layer 34 is provided inside the inlet section 22. The free section 23 is fixedly connected to the transmission gear 21 on the same axis. The outlet section 24 is fixedly connected to the panel 15 through it. The output part of the outlet section 24 extends into the interior of the drum 1. Through the setting of the filter layer 34, impurities in the bath liquid can be filtered to avoid the accumulation of impurities in the bath liquid from affecting the deashing effect.

[0037] The water spraying mechanism includes a water wheel 25, which is coaxially arranged inside the free section 23. The outlet section 24 has a nozzle 26 at its output. The bath liquid in the treatment chamber 3 is filtered by the filter layer 34 and then enters the cylinder. The water wheel 25 rotates at high speed with the transmission gear 21, thereby pressurizing the liquid in the cylinder 1 and causing the liquid to be sprayed out from the nozzle 26. The resulting high-pressure water flow washes the leather, removes residual ash and impurities attached to the leather surface, and further enhances the ash removal effect.

[0038] A first bevel gear 27 is coaxially fixedly connected to the central shaft 17 inside the mounting cylinder 10, and a second bevel gear 28 is fixedly connected to the inner wall of the outer cylinder 2. A rotating rod 29 is rotatably connected through the side wall of the mounting cylinder 10. A third bevel gear 30 is coaxially connected to one end of the rotating rod 29 that extends into the mounting cylinder 10. The first bevel gear 27 and the second bevel gear 28 are symmetrically arranged on both sides of the third bevel gear 30, and both the first bevel gear 27 and the second bevel gear 28 are meshed with the third bevel gear 30. Since the second bevel gear 28 is fixed, when the first bevel gear 27 rotates, it drives the third bevel gear 30 and the rotating rod 29 to revolve around the central shaft 17 while rotating on their own axis.

[0039] The other end of the rotating rod 29 extends into the processing chamber 3, and a cleaning brush 31 matching the filter layer 34 is coaxially fixedly connected to the end. As the cleaning brush 31 revolves around the central axis 17 with the rotating rod 29, it can remove impurities on the filter layer 34, preventing the filter layer 34 from becoming clogged and affecting the filtration effect. It should be noted that the cleaning brush 31 can rotate with the rotating rod 29, which improves the cleaning effect and makes the cleaning brush 31 wear out evenly, thus improving the service life of the cleaning brush 31.

[0040] The bottom of the outer cylinder 2 is provided with a sludge collection box 32, which is connected to the bottom interior of the processing chamber 3. The bottom of the sludge collection box 32 is provided with a drain valve 33, which is connected to the external bath liquid recovery system. Impurities in the processing chamber 3 are affected by gravity and deposited inside the sludge collection box 32, thus achieving the collection of impurities. When the drain valve 33 is opened, the impurities in the sludge collection box 32 can be discharged.

[0041] The working principle of this device is as follows: During operation, the ash skin after the ash removal process is washed with clean water to remove the residual free ash on the surface, and then placed inside the drum 1. At the same time, an appropriate amount of water and a deashing agent, such as ammonium sulfate, are injected into the drum 1 to form a deashing process bath.

[0042] After the equipment is started, the motor 16 outputs power to drive the central shaft 17 to rotate, which in turn drives the first gear 19 to rotate synchronously. The transmission gear 21 drives the internal gear ring 20 to rotate, causing the drum 1 to roll. The side wall of the lifting rib 4 supports the leather and lifts it off the surface of the bath liquid. After rising to a certain height, the leather falls off due to gravity. During the rotation of the drum 1, the leather inside continues to rise and fall freely, forming repeated beating and kneading action, which effectively destroys the gray structure of the leather surface, accelerates the dissolution rate of alkaline ash inside the leather, and improves the efficiency of the deashing operation.

[0043] During the deashing process, impurities such as calcium sulfate precipitate, leather scraps, hair root residue, and sulfide flocculents will be generated in the bath liquid. If these impurities accumulate over a long period, the bath liquid will become turbid and the deashing accuracy will be reduced. To solve this problem, this equipment integrates an internal circulation purification system for the bath liquid. When the drum 1 rotates, it synchronously drives the spiral blades 6 to rotate. Utilizing the fluid pushing principle of the spiral conveyor, the turbid bath liquid containing impurities in the drum 1 is introduced into the conveying channel 9 through the first connecting port 8, and then conveyed into the processing chamber 3 through the second connecting port 13. The turbid bath liquid in the processing chamber 3 is then filtered through the filter layer 34 to complete the solidification process. Liquid separation: various solid impurities in the bath liquid are intercepted by the filter layer 34, and the purified bath liquid enters the cylinder. It should be noted that during the rotation of the transmission gear 21, the water wheel 25 is driven to rotate at high speed, which creates a fluid pressurization effect on the bath liquid in the cylinder, causing the bath liquid to form a high-pressure water flow and be sprayed out from the nozzle 26. The high-pressure water flow can impact and wash the leather in the drum 1, removing residual ash and impurities attached to the surface of the leather, and further enhancing the ash removal effect. Relying on the continuous circulation purification mechanism, the accumulation of impurities and turbidity of the bath liquid inside the drum 1 is avoided, ensuring the stability of the ash removal effect.

[0044] It is worth noting that the lifting ribs 4, which are inclined inside the roller 1 of this device, can push the leather towards the tail of the roller 1 when the lifting ribs 4 support the leather. This ensures that the landing point of the leather is always close to the spray area of ​​the nozzle 26, so that the high-pressure rinsing water can act on the leather material and ensure the rinsing and descaling effect.

[0045] During operation, the central shaft 17 rotates continuously. Through the coordinated arrangement of the first bevel gear 27, the second bevel gear 28, and the third bevel gear 30, the rotating rod 29 is driven to revolve around the central shaft 17. At the same time, relying on the differential speed principle of gear meshing, the rotating rod 29 rotates on its own axis, and the cleaning brush 31 revolves with the rotating rod 29 to sweep and unclog the impurities trapped on the surface and in the pores of the filter layer 34, preventing the filter layer 34 from becoming clogged and causing poor circulation of the bath liquid. At the same time, the cleaning brush 31 rotates with the rotating rod 29, so that the bristles wear evenly, avoiding excessive wear in some areas and extending the service life of the cleaning components.

[0046] It is worth noting that during the internal circulation of the bath liquid in this device, the hot water in the hot water chamber 12 transfers heat energy to the processing chamber 3 through the heat exchange plate 11, thereby heating the circulating bath liquid and maintaining its temperature within the optimal deashing temperature range. The device is equipped with a temperature sensor and a controller (not shown). The temperature sensor collects the bath liquid temperature signal in real time and transmits the electrical signal to the controller. The controller analyzes and processes the data to adjust the heating power of the heating source 35, ensuring that the circulating bath liquid remains stable within the optimal temperature range for the deashing process, guaranteeing the deashing reaction rate and process stability, and improving the quality of the finished leather.

[0047] It is worth noting that during the operation of the equipment, the revolution of the rotating rod 29 can simultaneously drive the mounting cylinder 10 to rotate the heat exchange plate 11, thereby enhancing the convective heat exchange effect of the bath liquid and achieving rapid and uniform heating of the bath liquid.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
