Description

Technical Field

[0001] This utility model relates to the field of leather production technology, and in particular to a leather soaking tank with lifting and feeding function. Background Technology

[0002] The liming tank is an important piece of equipment or step in the tanning process for treating animal hides. In traditional tanning, animal hides undergo a series of chemical treatments to remove unwanted components (such as hair, fat, and some skin tissue) and prepare them for subsequent tanning. The liming process typically involves immersing the pre-treated (such as soaking, dehairing, etc.) raw hides in a solution containing lime (calcium hydroxide) and other chemicals (such as sodium sulfide, used to help dissolve the stratum corneum and hair roots). This process softens the skin tissue and helps to further remove residual hair roots and the epidermis, exposing the dermis to better accept the subsequent tanning process.

[0003] In the leather liming process of the leather tanning industry, liming tanks are used to store and treat solutions containing lime and other chemical agents in preparation for subsequent processing of animal hides. However, traditional liming tanks are inconvenient and dangerous to use due to their height; therefore, screw conveyors are usually used for the safe transport of these materials. When operators use screw conveyors, especially during the process of pouring lime into the feed inlet, a large amount of dust is inevitably generated. This dust is not only easily inhaled by users, posing a health threat such as causing respiratory diseases, but it can also spread into the surrounding environment, causing environmental pollution and reducing environmental friendliness. In addition, different types of agents or powders need to be mixed according to specific formula ratios before being added to the screw conveyor, which increases the complexity of operation and the risk of errors, while also prolonging preparation time and making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a leather liming tank with lifting and feeding, which can avoid the problems in the leather liming process in the leather tanning industry. Traditional liming tanks are too high, making it inconvenient and dangerous to add lime and powder directly. Usually, a screw feeder is used to safely transport materials. When lime is poured into the feed inlet, a large amount of dust is generated, which endangers the health of operators and pollutes the environment. Different agents need to be mixed in advance, which increases the complexity of operation, the risk of error, and the preparation time.

[0005] This utility model provides a leather soaking tank with lifting and feeding, including a leather soaking tank body. A screw feeder is installed on the left side of the leather soaking tank body and is in contact with the ground. An auxiliary component is provided on the top of the screw feeder.

A dust suction box is fixedly connected to the rear side of the feeding box. A filter component is fixedly connected to the inner cavity of the dust suction box.

[0006] In one specific implementation, a vacuum fan is installed on the rear side of the inner cavity of the vacuum chamber, and mounting boxes are connected to both the left and right sides of the rear side of the vacuum chamber.

[0007] In one specific implementation, a rotating rod is rotatably connected to the bottom of the inner cavity of the mounting box, a first motor is bolted to the top of the mounting box, the output shaft of the first motor is connected to the top of the rotating rod, and welding plates are fixedly connected to both the left and right sides of the inner cavity of the dust collection box, with long rods rotatably connected to the surface of the welding plates.

[0008] In one specific implementation, a positioning plate is fixedly connected to the surface of the long rod, and a plurality of symmetrically arranged cleaning plates are slidably connected to the inner cavity of the dust collection box. A push rod is connected to the side of the positioning plate away from the long rod, and one end of the push rod is slidably connected to the inner side of the cleaning plate.

[0009] In one specific implementation, one end of the long rod extends into the inner cavity of the mounting box, and two meshing bevel gears are respectively connected to one end of the long rod and the top end of the rotating rod. The surfaces of the two long rods are respectively equipped with first pulleys, and the two first pulleys are connected by belt drive.

[0010] In one specific implementation, a protective box is fixedly connected to the right side of the mixing tank, a second motor is bolted to the inner cavity of the protective box, and running rods are rotatably connected to both sides of the inner cavity of the mixing tank, with a placement plate fixedly connected to the surface of the running rods.

[0011] In one specific implementation, one end of the running rod extends through the inner cavity of the protective box and is connected to the output shaft of the second motor.

The bottom end of the stirring rod extends into the inner cavity of the mixing box, and discharge pipes are connected to both sides of the dust collection box.

[0013] The beneficial effects of this application are as follows: By setting up auxiliary components, the dust generated when pouring in agents such as lime can be effectively absorbed, significantly reducing dust dispersion. This not only avoids the potential health threats to operators from large amounts of dust, such as respiratory diseases, but also prevents dust from spreading to the surrounding environment, thereby greatly improving the environmental friendliness and cleanliness of the work area. In addition, multiple agents or powders can be uniformly mixed and directly discharged into the screw conveyor, ensuring the consistency and efficiency of material transmission. This avoids the need for pre-mixing processing steps, reduces the error risk caused by manual mixing, shortens preparation time, improves overall work efficiency and safety, and is easy to use.

[0023] In the leather liming process of the leather tanning industry, traditional liming tanks are inconvenient and dangerous to directly add lime and powder due to their height. Screw feeders are typically used for safe material transport. However, the addition of lime to the feed inlet generates a large amount of dust, endangering operator health and polluting the environment. Different agents need to be pre-mixed, increasing operational complexity, error risk, and preparation time. Therefore, the inventors have developed a leather liming tank with a lifting feeder. Through the inclusion of auxiliary components, dust is effectively drawn in when lime and other agents are added, significantly reducing dispersion, protecting operator health, and improving the environmental friendliness and cleanliness of the work area. Furthermore, it can uniformly mix various agents or powders and directly discharge them into the screw feeder, ensuring consistent and efficient transport, thus solving the aforementioned problems.

[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please refer to Figures 1 to 7This utility model embodiment provides a leather soaking tank with lifting and feeding, including a leather soaking tank body 1.

Several symmetrically arranged cleaning plates 312 are slidably connected to the inner cavity of the dust collection box 34, and the cleaning plates 312 are connected to the dust filter in the dust collection chamber 33. The surface of the filter component 35 is in contact with the positioning plate 325, which is connected to the push rod 313 on the side away from the long rod 311. One end of the push rod 313 is slidably connected to the inner side of the cleaning plate 312. One end of the long rod 311 penetrates into the inner cavity of the mounting box 37, and the area of ​​the long rod 311 in contact with the mounting box 37 is sealed. One end of the long rod 311 and the top of the rotating rod 38 are respectively connected to two meshing bevel gears 314. The surfaces of the two long rods 311 are respectively equipped with first pulleys 315, and the two first pulleys 315 are connected by belt drive. The right side of the mixing box 31 is fixedly connected to the protective box 316.

[0026] Please refer to Figures 2 to 7The inner cavity of the protective box 316 is bolted to a second motor 317. Both sides of the inner cavity of the mixing tank 31 are rotatably connected to running rods 318. Placement plates 319 are fixedly connected to the surface of the running rods 318. A sealing strip is installed on the surface of the side of the two placement plates 319 that contacts each other. One end of the running rod 318 penetrates into the inner cavity of the protective box 316 and is connected to the output shaft of the second motor 317. The area where the running rod 318 penetrates and contacts the protective box 316 is sealed. A positioning rod 326 is rotatably connected to the inner cavity of the protective box 316. Two meshing gears 324 are respectively connected to the surface of the positioning rod 326 and the adjacent running rod 318. The surfaces of rod 326 and running rod 318 are respectively connected to second pulleys 320, and the two second pulleys 320 are connected by belt drive. The top of the mixing box 31 is bolted to a third motor 322.

When the filter component 35 needs cleaning, the first motor 39 is activated, driving the rotating rod 38, the bevel gear 314, and the first pulley 315 to rotate, which in turn causes the long rod 311 to rotate and drive the positioning plate 325 to swing. The positioning plate 325 drives the push rod 313 to swing synchronously, causing the cleaning plate 312 to move in a straight line and effectively clean both sides of the filter component 35. The cleaned impurities are discharged after being connected to the discharge pipe 321 by an external dust collection device. After the chemicals or powders enter the mixing tank 31, the third motor 322 is activated, driving the mixing rod 323 to evenly mix the mixture. After mixing is completed, the second motor 317 is started, driving the running rod 318 to rotate the second pulley 320. The second pulley 320 drives the positioning rod 326 to rotate, and the positioning rod 326 drives the two gears 324 to mesh and rotate. The gears 324 drive the running rod 318, so that the two running rods 318 rotate in opposite directions, causing the placement plate 319 to swing downward, revealing a gap, allowing the processed material to fall into the screw feeder 2. Finally, the screw feeder 2 is started to transport the processed material to the leather soaking tank body 1 for use.

[0028] In summary, the working principle of a leather soaking ash tank with lifting and feeding according to an embodiment of this utility model is as follows: First, the user pours lime into the auxiliary component 3, and the auxiliary component 3 is used to suck up and filter the dust generated by pouring lime. Then, when faced with various agents or powders, the auxiliary component 3 is used to mix and stir them. After mixing and stirring, the processed material is discharged into the screw feeder 2, and then lifted and fed by the screw feeder 2 to the leather soaking ash tank for use.
