Description

Technical Field

[0001] The present application relates to the technical field of biochemical treatment of leather, and in particular to a rotary drum. Background Art

[0002] A rotary drum, also known as a tumbler, is a revolving drum. During the leather-making process, raw hides are typically placed inside the drum and turned over for washing, pickling, tanning, and dyeing. Fur can also be washed by turning it over with fine sawdust. Rotary drums are widely used in most wet-processing steps in leather making, as well as dry-processing steps like softening and raising.

[0003] When the drum rotates, the hides and skins inside the drum are subjected to continuous mechanical actions such as bending, stretching, pounding, and stirring, which can accelerate the chemical reaction process or change the physical properties of the hides and skins.

[0004] In the tanning and leather chemical industries, comparative testing of various processes is often required. During these comparative tests, conventional drums must be stopped and the drum compartment opened to add liquid during these tests. This operation is cumbersome and time-consuming, slowing down the test progress and reducing test efficiency. Utility Model Content

[0005] In order to improve the situation where liquid cannot be added during the operation of the drum and to improve the test efficiency of leather making comparison, the present application provides a drum.

[0006] The present application provides a rotary drum adopting the following technical solution:

[0007] A rotating drum includes a frame and a drum body, wherein the drum body is rotatably connected to the frame, the frame and the drum body are electrically connected and drive the drum body to rotate circumferentially, the drum body has a drum cabin for placing leather, the inner wall of the drum body is provided with convex piles for lifting leather, and a window plate for observing the status of the leather is provided on the side of the drum body away from the connection with the frame, and a fluid replenishing cylinder is provided on the window plate.

[0008] By adopting this technical solution, the frame provides a mounting platform for the drum and drives its rotation. The drum compartment houses leather and liquid reagents. Protruding studs are located on the inner wall of the drum, effectively lifting the leather as the drum rotates. A viewing panel allows for real-time monitoring of the leather's condition, enabling operators to add liquids at the appropriate time during comparative tanning tests. Compared to the previous method of stopping the drum before adding reagents, the addition of a liquid refilling cylinder allows liquids to be added during rotation, improving the efficiency of comparative tanning tests.

[0009] Optionally, the fluid replenishment cylinder includes a material holding cylinder and a feed pipe, the feed pipe passes through the window plate and is interconnected with the drum compartment, the fluid replenishment cylinder is fixedly connected to one end of the feed pipe away from the window plate, and the fluid replenishment cylinder and the feed pipe are interconnected.

[0010] By adopting this technical solution, the feed pipe passes through the viewing window and communicates with the drum chamber. The material holding barrel is fixedly connected to the feed pipe on the side away from the viewing window and communicates with the feed pipe. The material holding barrel is used to pour and guide the liquid material, while the feed pipe introduces the liquid material into the drum chamber. This allows the material to be added while the drum is rotating, improving the efficiency of tanning comparison tests.

[0011] Optionally, the diameter of the material holding barrel gradually decreases from the open end to the end connected to the feeding pipe.

[0012] By adopting the above technical solution, the diameter of the material holding barrel gradually decreases from the opening end to the feeding pipe end to form a funnel shape, thereby guiding the liquid material, facilitating the pouring of the liquid material, and helping to improve the test efficiency of leather making comparison.

[0013] Optionally, a filter screen for filtering liquid material is provided in the material holding barrel.

[0014] By adopting the above technical solution, the setting of the filter can filter the liquid material before entering the feed pipe. On the one hand, it can prevent solid impurities from affecting the experimental results. On the other hand, it can also prevent solid impurities from clogging the feed pipe with a smaller diameter, making it easier for the liquid material to enter the drum chamber during the rotation of the drum, thereby improving the test efficiency of leather making comparison.

[0015] Optionally, a plurality of claws for clamping and fixing the filter screen are provided circumferentially on the inner wall of the material holding barrel.

[0016] By adopting the above technical solution, compared with the method of placing the filter screen in contact with the material barrel, the setting of the claws can clamp and fix the filter screen, thereby improving the stability of the filter screen when placed in the material barrel, facilitating the stable addition of liquid material into the drum body, and helping to improve the test efficiency of leather making comparison.

[0017] Optionally, a supporting rod for supporting the fluid infusion cylinder is provided on the frame, a fixing part is fixedly connected to the frame, the supporting rod passes through the fixing part and is pressed against the inner wall of the fixing part, and one end of the supporting rod away from the fixing part is fixedly connected to the outer wall of the feed pipe.

[0019] Optionally, a hook is fixedly connected to the supporting rod, and the hook is away from the end connected to the supporting rod and is used to clamp and fix the fluid infusion cylinder.

[0020] By adopting the above technical solution, when the liquid material stays in the material holding barrel, it is easily affected by gravity, causing the material holding barrel to drive the entire liquid replenishing barrel to overturn. The hook is fixedly connected to the supporting rod and can clamp and fix the material holding barrel, thereby improving the stability of the liquid replenishing barrel installed on the window plate, which is beneficial to improving the stability of adding liquid material when the drum body rotates, thereby improving the test efficiency of leather making comparison.

[0021] Optionally, a placement opening for leather is provided at the center of the window plate, a rubber plug for closing the placement opening is clamped and fixed on the window plate, the feed pipe is passed through the central axis of the rubber plug, and the outer side wall of the feed pipe is pressed against the rubber plug.

[0022] By adopting this technical solution, the placement opening allows operators to place leather into the drum chamber, while the rubber stopper seals the opening and also allows the feed tube to pass through. The coordinated arrangement of the placement opening and the rubber stopper eliminates the need for repeated removal of the viewing panel, thereby improving the efficiency of comparative leathermaking tests.

[0023] Optionally, a convex ring for closing the window plate is provided on a side of the rubber stopper close to the inner wall of the drum body.

[0024] By adopting the above technical solution, the convex ring is arranged on the side of the rubber stopper close to the inner wall of the drum body. When the rubber stopper is inserted into the placement opening of the window plate, the convex ring and the window plate are pressed against each other, thereby improving the sealing effect of the rubber stopper on the window plate, which is beneficial to improving the efficiency of the leather making comparison test.

[0025] Optionally, the drum further includes a mounting strip for mounting the window panel, the number of the mounting strips being at least two, the two mounting strips being axially symmetrically arranged about the diameter of the window panel, the two mounting strips being fixedly connected to the drum body and the edge positions of the window panel respectively, a slot for snapping the window panel into and fixing the window panel is provided on the inner wall of the mounting strip, a locking piece is passed through the end position of the mounting strip, and the locking piece is threadedly connected to the two adjacent mounting strips.

[0026] By adopting the above technical solution, the two mounting strips are respectively fixedly connected to the drum body and the window plate and are axially symmetrically arranged about the window plate. A slot for the window plate to be inserted is provided on each of the two mounting strips. Locking parts are provided on the ends of the two mounting strips. When the window plate is inserted into the mounting strips on the drum body, the locking parts are threadedly fixed to the two mounting strips, thereby achieving the effect of installing the window plate on the drum body, improving the stability of the window plate installed on the drum body, and helping to improve the efficiency of the leather making comparison test.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

The feed pipe introduces the liquid material into the drum chamber, achieving the effect of adding material during the rotation of the drum. The filter screen filters the liquid material before entering the feed pipe to prevent solid impurities from affecting the experimental results. It can also prevent solid impurities from clogging the feed pipe with a smaller diameter, making it easier for the liquid material to enter the drum chamber during the rotation of the drum.
