Description

Technical Field

[0001] This utility model relates to the field of reclaimed rubber production technology, specifically a hot-feed rubber filter machine that facilitates filter screen replacement. Background Technology

[0002] A rubber filter is a machine that uses a screw to push and convey rubber to remove impurities from rubber or reclaimed rubber. It mainly consists of a screw, barrel, filter head, and transmission device. The filter head is equipped with a perforated plate and a filter screen. The perforated plate supports the filter screen and serves as a discharge port. It is a tapered hole that expands along the flow direction of the rubber. The filter screen inside the filter head mainly plays a filtering role. Therefore, the filter screen is a consumable and needs to be replaced regularly to ensure that the machine can operate normally.

[0003] A search revealed a Chinese patent application (application number 202223015454.5) disclosing a filter press for easy filter replacement, comprising a body, a filter press head, and a perforated plate. Through the coordinated use of the perforated plate, filter press head, filter screen, support rod, limiting rod, support block, limiting block, and fixing mechanism, the perforated plate is removed from the filter press head. The filter screen is pushed to the left, causing the support rod and limiting rod to move away from the inner cavity of the support block and limiting block. The filter screen is then replaced and reset, causing the support rod and limiting rod to move again and enter the inner cavity of the support block and limiting block. The limiting rod is then fixed by the fixing mechanism, and the perforated plate is installed on the filter press head, completing the replacement process.

[0004] However, existing patents have the following drawbacks:

[0005] The connection structure of this filter press, which is designed to facilitate filter replacement, is relatively complex, making it inconvenient to disassemble, install, and replace the filter. Utility Model Content
