Description

Technical Field

[0001] The present application relates to the technical field of rotary drum drainage, and in particular to a rotary drum drainage device for leather production. Background Art

[0002] The rotary drum drainage device for leather production mainly consists of a rotary drum, a drainage system, a control system, etc. The rotary drum is the main processing container, and a specific stirring and turning mechanism is provided inside it to ensure that the leather is evenly stressed during the processing. During the leather processing, the leather in the rotary drum is fully impregnated and reacted under the action of the stirring and turning mechanism. When drainage is required, the control system starts the drainage system and discharges the liquid in the rotary drum through a specific drainage pipe.

[0003] Traditional rotary drum drainage devices often fail to make intelligent adjustments according to the actual conditions of leather during the drainage process. As the characteristics of leather, such as humidity, thickness and texture, change with the processing process, fixed drainage time and drainage volume settings often lead to insufficient or excessive drainage, thus affecting the quality of leather and processing efficiency.

[0004] Therefore, this patent needs to be upgraded and modified based on the existing technology. Utility Model Content

Since the characteristics of the leather, such as humidity, thickness and texture, will change with the changes in the processing process, the fixed drainage time and drainage volume settings often lead to insufficient drainage or excessive drainage, thereby affecting the quality and processing efficiency of the leather.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a rotary drum drainage device for leather production, comprising a base and a rotary drum, wherein a fixed disc is fixedly connected to the top of one end of the base, a side of the rotary drum is rotatably connected to one side of the top of the fixed disc, and an isolation plate is fixedly connected to a position near one side of the fixed disc inside the rotary drum;

[0008] By adopting the above technical solution and setting an isolation plate, after the leather raw material enters the drum, the holes inside the isolation plate ensure that the water level inside the drum is equal and isolates the leather raw material at the same time. During the processing of the leather inside the drum, the leather's humidity, thickness, texture and other characteristics will change with the processing process. The water level inside the drum is detected in real time by a water level detection rod, and the water level inside the drum is adjusted by a water pump and a solenoid valve based on the detection result.

[0010] By adopting the above technical solution, the support of the drum is achieved, and the rotation of the gear can drive the drum to rotate as a whole, thereby realizing the turning of the leather raw materials inside the drum.

[0011] As a preferred technical solution of the present application, a motor is fixedly connected to the side of one of the supporting structures of the base, and the driving end of the motor is fixedly connected to the center position of the gear.

[0013] As a preferred technical solution of the present application, a baffle is fixedly connected inside the drum, and three baffles are provided and fixedly connected inside the drum according to a circumferential distribution.

[0014] By adopting the above technical solution, after the leather raw material enters the drum through the arrangement of the baffle, the baffle will drive the leather raw material inside the drum to turn over during the rotation of the drum, thereby ensuring sufficient impregnation and reaction of the leather raw material.

[0015] As a preferred technical solution of the present application, a feed port is provided at the outer side of the rotating drum, a sliding cover plate is slidably connected to the outer side of the rotating drum, and a handle is fixedly connected to the outer side of the sliding cover plate.

[0016] By adopting the above technical solution, the leather raw material is put into the drum through the feed opening, and then the sliding cover plate is slid to close the feed opening.

[0018] By adopting the above technical solution, three fixing bolts are provided at equidistant positions outside the slide groove. When the fixing bolts are set to open, the sliding cover is slid away from the feed port, and then the sliding cover is fixed by tightening the fixing bolts to prevent the sliding cover from moving. When the feed port is closed, the feed port is covered by sliding the sliding cover, and then the fixing bolts are tightened to ensure full coverage of the feed port.

[0019] Beneficial effects of this application:
