Description

Technical Field

[0001] This utility model relates to the field of leather processing equipment, and more specifically, it relates to a leather drum feeding device. Background Technology

[0002] Leather drums are widely used equipment in tanneries, and come in different types and specifications. The most common type is the wooden drum, which consists of a cylindrical drum body and a transmission mechanism. Inside the drum are protruding posts and lifting baffles. During operation, the leather and processing fluid are agitated together, accelerating the chemical reaction and altering the physical properties of the leather. Drums are used in most wet processing steps of leather tanning, as well as for softening and napping. The second type is the steel inclined drum, shaped like a cement mixer, used similarly to the wooden drum, but mostly in the preparation stage. Another type is the segmented drum, also known as the Y-shaped drum, made of stainless steel. Its characteristics include gentler mechanical action, higher loading capacity, and savings in chemical materials, making it suitable for the dyeing process.

[0003] In existing leather drum processing, operators typically load the leather to be processed after starting the drum. Then, once the equipment is running stably, they add chemicals and auxiliary materials to the feeding device. Some of these auxiliary materials are solid and need to be dissolved first. However, during the dissolution process in the feeding tank, insufficient dissolution time, inadequate stirring, or poor solubility of the auxiliary materials themselves may result in some materials not completely dissolving. Additionally, some impurities and particles may be generated during the dissolution process. These undissolved auxiliary materials and particles may enter the drum with the mixed liquid, thus affecting the appearance and quality of the leather.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a leather drum feeding device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a leather drum feeding device, comprising a feeding bucket and a pipe for connecting the drum, one end of the pipe being connected to the bottom of the feeding bucket, the feeding bucket comprising a bucket body and a base, the outer wall of the pipe being provided with external threads, the base being provided with a threaded hole for accommodating the pipe to pass through, the bottom of the bucket body being provided with an extension side and the inner diameter of the extension side being equal to the outer diameter of the base, the inner wall of the extension side being provided with a sealing ring, the top surface of the base being provided with a baffle plate one and a baffle plate two, the height of both baffle plate one and baffle plate two being higher than the top surface of the pipe, the outer wall of baffle plate one being in contact with the inner wall of the bucket body, the inner wall of baffle plate two being in contact with the outer wall of the pipe body, and a filter assembly being rotatably connected to baffle plate two and the filter assembly being located directly above the pipe opening.

[0007] The present invention is further configured such that: the filter assembly includes a filter plate and a counterweight, one end of the filter assembly is rotatably connected to the baffle plate two via a rotating shaft, and the counterweight is fixedly connected to the other end of the filter assembly.

[0008] The present invention is further configured such that: the counterweight is vertically arranged, the side of the counterweight near the rotating shaft is in contact with the outer wall of the second baffle, and the outer side of the second baffle is provided with a guide surface that is inclined downward.

[0009] The present invention is further configured such that the baffle is detachably connected to the base.

[0010] The present invention is further configured such that: a slot for accommodating an inserted baffle is provided on the top surface of the base, and the width of the slot is larger as it approaches the opening.

[0011] The present invention is further configured such that: a through groove is provided on the barrel body, and a scale plate is provided in the through groove, the scale plate being made of transparent plastic.

[0012] The present invention is further configured such that: two symmetrically arranged handles are provided on the bottom surface of the base.

[0013] The present invention is further configured such that both the barrel body and the base are made of stainless steel.

[0014] The present invention is further configured such that the baffle is integrally formed on the base.

[0015] In summary, this utility model has the following beneficial effects:

[0016] By rotating the filter assembly on the second baffle, which includes a filter plate and a counterweight, undissolved solid auxiliary material particles and impurities can be effectively filtered out, preventing these impurities from entering the drum through the pipe, thereby improving the quality and effect of leather processing.

[0017] By setting up baffle one and baffle two, when undissolved solid additives and impurity particles accumulate at the bottom of the tank, the operator can remove the base for cleaning. Baffle one and baffle two provide space for them and effectively prevent these particles from entering the pipe directly, thereby avoiding pipe blockage and ensuring smooth feeding.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] A leather drum feeding device, such as Figure 1As shown, the device includes a feeding tank and a pipe 1 for connecting to the rotating drum. One end of the pipe 1 is connected to the bottom of the feeding tank, ensuring that the liquid can flow smoothly into the rotating drum. The feeding tank consists of a tank body 2 and a base 3. This split design facilitates disassembly and cleaning, improving the ease of equipment maintenance. Specifically, both the tank body 2 and the base 3 are made of stainless steel. Stainless steel has advantages such as corrosion resistance, high strength, and long service life, making it suitable for feeding devices that come into contact with chemical agents and excipients. This ensures the durability and reliability of the equipment, reduces maintenance costs, and extends the service life of the equipment.

[0028] The outer wall of pipe 1 is provided with external threads, and the base 3 has a matching threaded hole. Through the cooperation of the external threads and the threaded hole, the base 3 can descend or rise vertically along the external threads of pipe 1, realizing a detachable connection between the base 3 and pipe 1. This design not only facilitates installation and disassembly, but also enhances the flexibility of the equipment, enabling it to adapt to drums of different heights and improving the versatility of the equipment. Furthermore, the bottom surface of the base 3 is provided with two symmetrically arranged handles 15. By providing handles 15, the operator can apply force to the handles 15 when rotating the base 3, thereby facilitating the disassembly of the base 3 and improving the efficiency of assembly and disassembly.

[0029] The bottom of the barrel 2 is provided with an extension edge 4, the inner diameter of which is equal to the outer diameter of the base 3, ensuring a tight fit between the two. A sealing ring 5 is provided on the inner wall of the extension edge 4. The sealing ring 5 effectively enhances the sealing between the barrel 2 and the base 3, prevents liquid leakage, reduces material waste, and avoids environmental pollution caused by leakage, thereby improving the safety and environmental friendliness of the equipment.

[0030] The top surface of the base 3 is equipped with baffle 6 and baffle 7. The height of both baffle 6 and baffle 7 is higher than the top surface of the pipe 1. The outer wall of baffle 6 fits against the inner wall of the barrel 2, and the inner wall of baffle 7 fits against the outer wall of the pipe 1. Baffle 6 and baffle 7 provide a space for undissolved solid additives and impurity particles, effectively preventing these particles from directly entering the pipe 1. After the equipment has been used for a long time, the operator can unscrew the base 3 along the external thread on the pipe body and clean the impurities and solid additives located between baffle 6 and baffle 7, thereby preventing them from accumulating in the barrel. In addition, the height setting of baffle 6 and baffle 7 further enhances the blocking effect on solid additives and impurity particles, preventing liquid leakage when the base 3 is disassembled, and improving the stability and reliability of the entire feeding device.

[0031] A filter assembly 8 is rotatably connected to the baffle 7, located directly above the pipe opening. The filter assembly 8 includes a filter plate 9 and a counterweight 10. One end of the filter assembly 8 is rotatably connected to the baffle 7 via a rotating shaft, and the counterweight 10 is fixedly connected to the other end of the filter assembly 8. The counterweight 10 is vertically arranged, with its side near the rotating shaft fitting against the outer wall of the baffle 7. An inclined downward guide surface 11 is provided on the outer side of the baffle 7. By setting up the filter assembly 8, undissolved solid auxiliary materials and impurities can be prevented from entering the drum through the pipe 1, protecting the leather inside the drum and improving the quality of leather processing. It also prevents impurities from accumulating and clogging in the pipe 1. By setting up the counterweight 10 and the guide surface 11, the filter plate 9 will naturally press against the baffle 7 under the action of gravity, thereby preventing impurities from entering the pipe 1 through gaps and improving the filtration effect.

[0032] Baffle 6 is detachably connected to base 3, while baffle 7 is integrally formed on base 3. The integral forming design ensures high connection strength between baffle 7 and base 3. Both baffle 6 and baffle 7 are circular. A slot 12 for inserting baffle 6 is provided on the top surface of base 3, and the width of slot 12 increases as it approaches the opening. When the operator holds handle 15, rotates base 3, and removes base 3 along pipe 1, the liquid between baffle 6 and baffle 7 can be cleared with tools. Then, baffle 3 is applied upward to remove it from base 3. At this point, the operator can clean various impurities on the top surface of base 3. After cleaning, baffle 6 is inserted into the slot, and base 3 is rotated in the opposite direction to move upward again and fix it to the feeding bucket. This operation makes the impurity cleaning process more convenient, improves cleaning efficiency, and also extends the service life of the equipment.

[0033] A through groove 14 is provided on the barrel body 2, and a scale plate 13 is provided inside the through groove 14. The scale plate 13 is made of transparent plastic. The operator can visually observe the liquid level in the barrel body 2 through the scale plate 13, thereby more accurately controlling the amount of material added, improving the accuracy of material addition and the convenience of operation. At the same time, when disassembly is required, the remaining liquid level inside can also be observed through the scale plate 13, thereby avoiding liquid leakage during disassembly and improving the safety of the equipment.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
