Description

Technical Field

[0001] The utility model relates to a side scraper structure for a rotary drum flaker, belonging to the technical field of rotary drum flakers. Background Art

[0002] The production of products such as caprolactam and refined naphthalene mostly uses a rotary drum flaker. Existing rotary drum flakers are all equipped with scrapers, which are used to scrape the crystallized products on the drum of the flaker. Since the coaxiality of the flaker drum has errors during the manufacturing or use process, and the coaxiality error will continue to increase during the production process, the drum will jump relative to the side scraper. During the scraping process, the scraping will not be thorough, the efficiency will continue to decline, and the production efficiency will be reduced. In addition, the gap between the scraper blade and the drum is unstable, which will cause the blade to wear quickly and the equipment to be frequently repaired, affecting the production efficiency. Utility Model Content

[0003] In view of the above-mentioned defects existing in the prior art, the utility model provides a floating side scraper structure, whose scraper blade has a floating function, which can keep the gap between the scraper blade and the drum stable, extend the service life of the scraper blade, and improve production efficiency.

[0004] The utility model is realized through the following technical scheme: a floating side scraper structure, characterized in that it includes a side scraper blade, a side scraper blade bracket, a stabilizing wheel, a side scraper fixed shaft, and an elastic support rod. The side scraper fixed shaft is arranged on the side of the rotary drum of the flaker in parallel with the axis of the rotary drum of the flaker, and the side scraper fixed shaft is arranged in the shell of the flaker. There is at least one side scraper blade, and the side scraper blade is movably connected to the side scraper fixed shaft through the side scraper blade bracket. There is a certain gap between the blade edge of the side scraper blade and the surface of the rotary drum. One end of the elastic support rod is connected to the side scraper blade bracket, and the other end of the elastic support rod is fixed on the shell of the flaker. The stabilizing wheel is rotatably connected to the front side of the side scraper blade bracket and contacts with the surface of the rotary drum of the flaker.

[0005] In the utility model, the pressure of the elastic support rod acts on the side scraper blade bracket, so that the side scraper blade always has a force close to the drum, and at the same time, the stabilizing wheel is always in contact with the drum surface through the force of the elastic support rod. When the drum rotates, the stabilizing wheel moves synchronously with the drum. The two forces of the stabilizing wheel and the elastic support rod interact with the side scraper bracket to maintain a certain gap between the side scraper blade and the drum. When the drum bounces, a constant gap can be maintained between the side scraper blade and the drum surface, which can improve production efficiency, improve product quality, and extend the service life of the scraper blade.

[0006] Furthermore, a stabilizing wheel adjusting rod is provided on the side scraper blade support, and the stabilizing wheel is connected to the side scraper blade support through the stabilizing wheel adjusting rod. The stabilizing wheel can be adjusted through the stabilizing wheel adjusting rod to adapt to different scraper gap requirements.

[0007] Furthermore, the elastic support rod is a compression spring.

[0008] The beneficial effects of the utility model are as follows: in the side scraper structure of the utility model, the side scraper blade has a floating function, which can float following the jumping of the drum, so that the side scraper blade always maintains a constant distance from the drum, and no wear between the blade and the drum occurs, which can reduce the equipment failure rate, improve production efficiency, and improve product quality. By limiting the relative motion gap between the scraper and the drum, the service life of the blade can be extended. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The present invention is further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings:

[0016] As shown in the attached drawings, a floating side scraper structure is arranged on the side of the drum 1 of the flaker, and includes a side scraper blade 2, a side scraper blade bracket 3, a stabilizing wheel 6, a side scraper fixed shaft 8, and an elastic support rod 5. Among them, the side scraper fixed shaft 8 is arranged on the side of the drum 1 of the flaker parallel to the axis of the drum 1, and the side scraper fixed shaft 8 is arranged in the flaker housing 9. The side scraper fixed shaft 8 can be fixed on the flaker housing 9, and can also be connected to the flaker housing 9 through a bearing seat support. The side scraper blade 2 can be provided with one or more blades according to the length of the drum. The side scraper blade 2 is fixed to the front of the side scraper blade bracket 3, and the side scraper blade bracket 3 is installed on the side scraper fixed shaft 8. The stabilizing wheel 6 is rotatably connected to the front side of the side scraper blade bracket 3. The side scraper blade bracket 3 can drive the side scraper blade 2 to rotate. To ensure that the side scraper blade 2 can rotate, when the side scraper fixed shaft 8 adopts a structural form of fixed connection with the flaker housing 9, the side scraper blade bracket 3 and the side scraper fixed shaft 8 adopt a rotatable connection mode, for example, the side scraper blade bracket 3 can be movably mounted on the side scraper fixed shaft 8; when the side scraper fixed shaft 8 adopts a structural form of bearing support, the side scraper fixed shaft 8 can rotate through the bearing, and the side scraper blade bracket 3 and the side scraper fixed shaft 8 adopt a fixed connection mode, and the rotation of the side scraper fixed shaft 8 drives the side scraper blade 2 to rotate. The side scraper blade bracket 3 is connected to the flaker housing 9 through an elastic support rod 5, one end of the elastic support rod 5 is connected to the side scraper blade bracket 3 through a connecting seat 4, and the other end of the elastic support rod 5 is connected to the flaker housing 9. The elastic support rod 5 has a certain elasticity, which can apply a certain pressure to the side scraper blade bracket 3. The stabilizing wheel 6 contacts the surface of the drum 1 of the flaker, and the blade edge of the side scraper blade 2 and the drum 1 are supported by the stabilizing wheel to maintain a certain gap. The elastic support rod 5 can adopt a compression spring to adjust the distance between the blade and the material according to the size of the production load. In the utility model, the side scraper blade 2 forms a fixed structure through the side scraper blade bracket 3 and the stabilizing wheel 6. During operation, the elastic support rod 5 can apply a certain pressure to the side scraper blade bracket 3, so that the stabilizing wheel 6 contacts the surface of the drum, so that the side scraper blade always has a force close to the drum, and the stabilizing wheel supports the side scraper blade bracket and the drum to always maintain a relative gap.

[0017] The stabilizing wheel 6 and the side scraper blade bracket 3 in the utility model can be fixedly connected to each other to adjust the stabilizing wheel. Preferably, the side scraper blade bracket 3 is provided with a stabilizing wheel adjusting rod 7, which is a threaded rod, which is threadedly connected to the side scraper blade bracket 3 and connected to the mounting seat of the stabilizing wheel 6. The stabilizing wheel 6 can be adjusted by the stabilizing wheel adjusting rod 7.

[0018] The other parts of this embodiment are all prior art and will not be described in detail here.
