Abstract
Description
Technical Field
[0001] The present application relates to the technical field of scraper quick-change structures, and in particular to a quick-change device for filter scrapers. Background Art
[0002] The scraper of the SCF self-cleaning filter has been in use since it was first installed. If the scraper is worn and cannot be used, it is necessary to shut down the machine to cool down and remove the entire scraper device. The scraper must be replaced on the table. The structure has defects: 1. Shutdown will cause a reduction in production for the equipment, and replacing it and restarting it will cause energy loss. 2. When shutting down and removing the entire set of scrapers, the scraper device must be removed before the temperature drops below 200 degrees. Otherwise, the plastic will agglomerate at low temperature and the scraper will get stuck in the filter body. If the scraper device is removed when the temperature is high, since the scraper device is directly installed on the body, the body temperature is 260 degrees, and there is a risk of scalding. 3. There are many steps to replace the original scraper device, and the manual replacement time is long and the cost is high. Utility Model Content

Obviously, the drawings described below are only some embodiments recorded in the present application. For ordinary technicians in this field, it is easy to obtain other drawings based on these drawings without creative work.
[0013] Figure 1 Shown is a three-dimensional view of a quick-change device for a filter scraper in a specific embodiment of the utility model;
[0014] Figure 2 Shown is a side structural schematic diagram of a quick-change device for a filter scraper in a specific embodiment of the utility model. DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] Ginseng Figure 1~2As shown, the quick-change device for the filter scraper in this embodiment includes a fixed block 1, a scraper 2, a pair of moving blocks 3 and a cylinder 4. The upper end surface of the fixed block 1 is recessed with a cavity 5, and the front and rear ends of the fixed block 1 are respectively provided with an outlet 6 and an inlet 7 both connected to the cavity 5. The scraper 2 and the pair of moving blocks 3 are both arranged in the cavity 5, and the end of the scraper 2 facing the outlet extends to the outside of the outlet 6. The pair of moving blocks 3 are symmetrically arranged on the side of the scraper 2 facing the inlet 7. The end of the moving block 3 facing the scraper 2 is convexly provided with a first protrusion 8 extending to the bottom of the scraper 2, and the first protrusion 8 is recessed with a first screw hole 9. A first fixing bolt 10 that penetrates the scraper 2 and is threadedly connected to the first screw hole 9 is provided above the scraper 2. The cylinder 4 is fixedly connected to the fixed block 1 and its output end passes through the inlet 7 and is fixedly connected to the moving block 3.
[0017] Furthermore, a limit block 11 is provided in the cavity 5, a second screw hole 12 is recessed on the bottom surface of the cavity 5, a second bolt 13 is provided above the limit block 11 and passes through the limit block 11 and is threadedly connected to the second screw hole 12, a pair of moving blocks 3 have second protrusions 14 protruding on the facing end surfaces, and a third protrusion 15 is protruding on the limit block 11 and extends above the two second protrusions 14.
