Description

Technical Field

[0001] This utility model relates to the field of synthetic resin production technology, and in particular to a discharge port structure for a synthetic resin grinding mill. Background Technology

[0002] Grinding mills are commonly used equipment in synthetic resin production. After the raw materials are ground in the grinding mill, they need to be screened at the outlet to retain large particles and circulate them for further grinding, ultimately achieving the desired particle size for production. Currently, grinding mills typically have the filter screen directly installed at the outlet material discharge point. This screen needs to be removed and replaced after a period of time, leading to the inconvenience of needing to stop the machine to replace or clean the filter, affecting production continuity. Furthermore, traditional filter screens are secured with multiple clips or screws, requiring the removal of multiple screws or clips during disassembly, further impacting the efficiency of filter replacement.

[0003] To solve the above problems, a discharge port structure for a synthetic resin grinding mill is provided. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a discharge port structure for a synthetic resin grinding mill, which effectively solves the problem that the filter screen at the discharge part of the existing sand mill needs to be replaced by stopping the machine, and the replacement and installation process is relatively cumbersome.

[0005] The technical solution includes a vertical cylinder, with an outer ring cylinder fitted on the outer side of the upper end of the vertical cylinder. The bottom of the outer ring cylinder is fixed to the vertical cylinder, and an annular gap is formed between the inner side wall of the outer ring cylinder and the outer side wall of the vertical cylinder. A feed cylinder is fixed to the left side of the upper end of the outer ring cylinder, and the left end of the feed cylinder is fixed to the grinding machine via a flange. A rotating frame is located inside the annular gap, and multiple detachable filter plates are installed on the rotating frame. There is a feed groove on the side wall of the outer ring cylinder corresponding to the feed cylinder, and a clearance groove is opened at the right end of the outer ring cylinder, allowing the filter plates to pass smoothly through the clearance groove.

[0006] Furthermore, the rotating frame includes two rings coaxial with the outer ring cylinder. The two rings are fixed together by multiple vertical rods evenly distributed around the circumference. The multiple vertical rods divide the outer edge of the two rings into multiple rectangular frames, and a filter plate is installed in each frame.

[0007] Furthermore, a rubber sealing strip is installed on the edge of the filter plate.

[0008] Furthermore, the outer circular surface of the rotating frame contacts the inner wall of the outer ring cylinder, while the inner circular surface of the rotating frame contacts the outer wall of the vertical cylinder.

[0009] Furthermore, the upper end of the rotating frame is provided with multiple handles to facilitate rotating the rotating frame.

[0010] This utility model has a clever structure that allows for filter replacement without shutting down the machine. Multiple filters can be installed at once, extending the cleaning cycle. The structure is simple and reasonable, without adding any extra redundancy. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 5 The present invention includes a vertical cylinder 1, an outer ring cylinder 2 fitted on the outer side of the upper end of the vertical cylinder 1, the bottom of the outer ring cylinder 2 being fixed to the vertical cylinder 1, and an annular gap being formed between the inner side wall of the outer ring cylinder 2 and the outer side wall of the vertical cylinder 1. A feed cylinder 3 is fixed to the left side of the upper end of the outer ring cylinder 2, and the left end of the feed cylinder 3 is fixed to the grinding machine via a flange 4. A rotating frame 5 is provided in the annular gap, and multiple detachable filter plates 6 are installed on the rotating frame 5. There is a feed groove 7 on the side wall of the outer ring cylinder 2 corresponding to the feed cylinder 3, and a clearance groove 8 is provided at the right end of the outer ring cylinder 2, through which the filter plates 6 can pass smoothly.

[0018] The rotating frame 5 includes two rings coaxial with the outer ring cylinder 2. The two rings are fixed together by multiple vertical rods evenly distributed around the circumference. The multiple vertical rods divide the outer edge of the two rings into multiple rectangular frames, and a filter plate 6 is installed in each frame.

[0019] To ensure the sealing between the filter plate 6 and the ring or vertical rod, a rubber sealing strip 9 is installed on the edge of the filter plate 6.

[0020] The outer circular surface of the rotating frame 5 contacts the inner wall of the outer ring cylinder 2, while the inner circular surface of the rotating frame 5 contacts the outer wall of the vertical cylinder 1.

[0021] The rotating frame 5 is provided with multiple handles 10 at its upper end for easy rotation.

[0022] It is worth noting that a single rectangular frame can completely cover the feed chute 7; if necessary, sealing strips can be installed on the frame around the rotating frame 5 to ensure a tight seal.

[0023] When using, such as Figure 1 , 2 As shown in Figure 3, after the raw material is ground by the sand mill, it reaches the outlet of the mill. The material passes through the feed trough 7 and reaches the leftmost filter plate 6, and then flows down the vertical cylinder 1. After a period of time, the filter plate 6 is blocked by large particles and needs to be replaced. Simply squeeze the handle 10 and rotate the frame 5 to make the next clean filter plate 6 reach the feed inlet. When the blocked filter reaches the relief groove 8, it can be removed and replaced through the relief groove 8.

[0024] This utility model has a clever structure that allows for filter replacement without shutting down the machine. Multiple filters can be installed at once, extending the cleaning cycle. The structure is simple and reasonable, without adding any extra redundancy.
