Description

TECHNICAL FIELD

[0001] The utility model relates to food processing equipment field especially quick detachable drum screen. BACKGROUND

[0002] The drum screen is mainly involved in the processing, cleaning and sorting of soft-shelled turtles in the soft-shelled turtle slaughter workshop. As a common screening device, the drum screen plays an important role in the soft-shelled turtle slaughter workshop and is mainly applied. Through the screening function of the drum screen, soft-shelled turtles can be classified and sorted according to certain standards. This helps subsequent processing processes, such as distributing different processing areas or performing different treatments (e.g., treating larger or smaller soft-shelled turtles).

[0003] The disassembly and cleaning of the drum screen after use are necessary steps to ensure its normal operation and prolong the service life of the equipment. Since the drum screen comes into contact with a large amount of organic matter when processing soft-shelled turtles, these impurities are easily attached to the screen mesh and the surface of the drum. If not cleaned in time, it may affect the screening effect and even cause equipment failure. Therefore, regular disassembly and cleaning are particularly important. The drum screen is usually equipped with some auxiliary devices, such as a feed inlet, a discharge outlet, and a cleaning nozzle. Before disassembly, these accessories need to be removed to ensure that they are not damaged during the cleaning process. When disassembling, the positions and installation methods of each component should be recorded to facilitate subsequent reassembly. The core components of the drum screen are the screen mesh and the drum itself. When disassembling, the screen mesh is first separated from the drum, which can usually be done by loosening the fixing bolts or buckles. For some components that are fixed more firmly, appropriate tools (such as wrenches, screwdrivers, etc.) are used to easily disassemble them. During the disassembly process, careful operation is required to avoid damaging the screen mesh or the surface of the drum.

[0004] However, the existing drum screen often encounters the following problems during use: During the traditional manual disassembly of the drum screen, workers need to perform a lot of physical labor, such as moving heavy objects, adjusting the position of the equipment, and disassembling screws. These operations not only take time and effort, but also often involve a lot of labor intensity, especially when disassembling heavy and bulky screen drums and other mechanical components. Workers may feel tired after a long time of operation, which may affect work efficiency and safety. In addition, due to the complicated operation and lack of effective support system, workers are prone to safety accidents during disassembly due to unstable mechanical components or incorrect operation, which may cause equipment damage or personal injury, posing a great safety hazard. SUMMARY

The sliding roller 4's own rolling motion causes the support frame 2 to rotate axially; rotation of the screen cylinder 3 causes the support frame to rotate. The number of sliding rollers 4 is sufficient to support the screen cylinder 3. The propulsion mechanism 5 is mounted on one side of the mounting frame 1. The sliding roller 4 provides the conditions for the axial rotation of the screen cylinder 3, allowing the screen cylinder 3 to retain its original screening function. The rollers can be made of high-strength, wear-resistant materials, such as hard alloys or steel alloys, to ensure that they do not wear out too quickly over long-term use.

[0039] In this embodiment, in order to facilitate the push screen cylinder 3 to set the boost mechanism 5, including: the baffle 51 is installed on the installation frame 1; the baffle 51 is transversely provided with a strip-shaped slide 52, the sliding member 53 is located on one side of the baffle 51, one end of the push piece 54 is connected with the attached surface of the sliding member 53, the other end of the push piece 54 is provided in the strip-shaped slide 52 and contacts with the side wheel surface of the screen cylinder 3; when the other end of the push piece 54 contacts with the side wheel surface of the screen cylinder 3, the screen cylinder 3 can be pushed by the movement of the push piece 54 to achieve the effect of screen boost.
