一种单壁刮板式换热器刮刀结构
By designing a rubber snap-fit structure with a snap-fit and a beveled groove inside the scraper, the problem of scrapers falling off due to material impact and equipment deformation during sauce production is solved, achieving a stable connection of the scraper and improving the stability and heat exchange efficiency of the equipment.

AI Technical Summary
Existing straight-mouth grooved scrapers are prone to loosening due to material impact and equipment deformation during sauce production, causing the scraper to fall off, affecting heat exchange efficiency and production continuity.
The scraper is designed with symmetrical slots inside, with anti-slip pads fixedly connected to the inner wall of the slots. One side of the slot has a slanted groove that engages with the rubber pad. The scraper is secured by a rubber dovetail block and the dovetail groove, combined with a limiting groove.
This solves the problem of scrapers falling off during rotation, ensures a secure connection between the scrapers and external components, reduces equipment failure frequency and maintenance costs, and improves equipment stability and heat exchange efficiency.

Abstract
Claims
1. A single-walled scraped-surface heat exchanger scraper structure comprising a scraper blade (1), characterised in that: The scraper (1) has symmetrical slots (4) inside. The inner wall of the slot (4) is fixedly connected to an anti-slip pad (41). A slanted slot (5) is opened on one side of the slot (4). The slanted slot (5) is L-shaped. A rubber pad (6) is slidably connected to the inner wall of the slanted slot (5). A dovetail groove (51) is opened on one side of the longitudinal straight part of the slanted slot (5). A rubber dovetail block (61) is fixedly connected to one side of the rubber pad (6). The rubber dovetail block (61) is fitted into the inner wall of the dovetail groove (51). The lateral width of the rubber dovetail block (61) is slightly larger than the lateral width of the dovetail groove (51).
2. A single-walled scraped surface heat exchanger scraper according to claim 1, characterized in that: The oblique slot (5) has symmetrically provided grooves (52) on the inner wall of the longitudinal straight opening. The bottom end of the groove (52) has a first limiting groove (53). The rubber pad (6) has symmetrically provided first semi-circular rubber blocks (62) on both sides. The first semi-circular rubber blocks (62) are slidably connected to the inner wall of the groove (52). The first semi-circular rubber blocks (62) are fitted into the inner wall of the first limiting groove (53). The diameter of the first semi-circular rubber blocks (62) is slightly larger than the diameter of the groove (52).
3. A single-walled scraped surface heat exchanger scraper according to claim 1, characterized in that: The inner wall of the longitudinal straight opening of the oblique slot (5) is also provided with a second limiting groove (54), and the bottom end of the rubber pad (6) is fixedly connected with a second semi-circular rubber block (63), which is fitted into the inner wall of the second limiting groove (54).
4. A single-walled scraped surface heat exchanger scraper according to claim 1, characterized in that: The scraper (1) has a scraping part (2) at the bottom and an arc-shaped part (3) at the top.
5. A single-walled scraped surface heat exchanger scraper according to claim 1, characterized in that: The top of the rubber pad (6) is provided with an arc surface (64) that matches the arc part (3), and the bottom corner of the rubber pad (6) is provided with a rounded corner part (65) that matches the inner wall of the oblique groove (5).
6. A single-walled scraped surface heat exchanger scraper according to claim 1, characterized in that: The scraper (1) has a pressure relief hole (7) in the middle, and the pressure relief hole (7) is designed in a trumpet shape.
