Scraper for three-phase horizontal spiral pusher centrifuge

Abstract

The utility model discloses a scraper for a three-phase horizontal spiral pushing centrifugal machine, which is characterized by comprising a fixed end for fixedly mounting the scraper on a spiral blade of the centrifugal machine and a scraper end for scraping residues to prevent the residues from entering a water outlet pipe to cause blockage, the front end of the scraper end is provided with an inclined end used for reducing the gap between the scraper end and the rotary drum so as to improve the residue intercepting capacity. The inclined end is arranged at the front end of the scraper end, so that the inclined end at the front end of the scraper end is more matched with a rotary drum, a gap between the scraper end and the rotary drum is smaller, and residues are more effectively prevented from entering the water outlet pipe of the pushing centrifugal machine to cause blockage of the water outlet pipe; therefore, oil quality reduction caused by the fact that the water level in the liquid collecting box of the material pushing centrifugal machine rises to enter an oil phase due to blockage of the water outlet pipe is avoided, the service life of the material pushing centrifugal machine is prolonged, and shutdown overhaul frequency is reduced.

Description

TECHNICAL FIELD

[0001] The utility model relates to a scraper for three -phase horizontal helical pushing material centrifuge, specifically refers to a scraper for three -phase horizontal helical pushing material centrifuge. BACKGROUND

[0002] The main principle of the three -phase horizontal helical pushing material centrifuge in the prior art is that the dewatering (the mixture of water, oil and residue) in the kitchen waste enters the screw inside through the feeding pipe at the large end, the residue is pushed to the drum edge by the centrifugal force of high-speed rotation, the residue is pushed out from the small end by the screw rotating in the same direction with a certain differential speed, the liquid phase (water and oil) enters the liquid collection box at the large end from the position close to the center of the drum, and the water phase and the oil phase are separated and output by adjusting the centripetal valve, wherein the scraper is installed on the screw blade, and the scraper is used to prevent the residue that does not go to the small end from entering the liquid collection box and then entering the water outlet pipe to cause the water outlet pipe to be blocked.

[0003] However, the scraper in the prior art has poor wear resistance, is easily worn during the scraping process, and cannot completely scrape off the residue after serious wear, so that the three -phase residue enters the water outlet pipe and causes the water outlet pipe to be blocked, once the blockage occurs, the drainage is not smooth, the oil phase and water are raised, the quality of crude oil is affected, the oil extraction capacity is reduced, the overall oil extraction rate is reduced, and the production organization is interrupted. Therefore, a scraper for three -phase horizontal helical pushing material centrifuge is provided. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the above problems and provides a scraper for three -phase horizontal helical pushing material centrifuge.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme, a scraper for three -phase horizontal helical pushing material centrifuge, characterized by the scraper comprising a fixed end for being fixedly installed on the screw blade of the centrifuge and a scraper end for scraping off the residue to prevent the residue from entering the water outlet pipe and causing blockage, and the front end of the scraper end is provided with an inclined end for reducing the gap between the scraper end and the drum and improving the residue interception capacity.

[0006] Further preferably, a wear-resistant coating for increasing the wear resistance of the scraper is arranged on the scraper end.

[0007] The utility model discloses a beneficial effect: through setting up the inclined end in the scraper end front end, through the setting of inclined end, make the inclined end of scraper end front end and the drum more fit, make the gap between scraper end and the drum smaller, more effectively prevent the residue from entering the water outlet pipe of push material centrifuge and cause the water outlet pipe block, thereby avoid the water level in the push material centrifuge collecting tank because of the water outlet pipe block and cause the oil product quality to drop, improve the service life of push material centrifuge, reduce the shutdown maintenance frequency.

[0008] Through setting up wear -resisting coating on the scraper end, be used for enhancing the wear resistance of scraper, improve the service life of scraper, reduce the use cost. BRIEF DESCRIPTION OF DRAWINGS

[0014] Below, we combine the drawings to the scraper of a three -phase horizontal helical push material centrifuge of the utility model described further.

[0015] It needs to be explained that, all directionality indications such as upper, lower, left, right, front, back in the embodiment of the utility model are only used to explain the relative positional relationship, movement condition etc. between each component in a certain specific attitude such as shown in the drawings, if the specific attitude changes, then the directionality indication also changes accordingly.

[0016] In the utility model, unless another explicit provision and limitation, the terms "connect", "fix" etc. should be understood broadly;For example, "fixed" can be fixed connection, also can be detachable connection, or integrated;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be the intercommunication of two elements or the interaction of two elements, unless another explicit limitation. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0017] Reference Figures 1-4As shown in the figure, a kind of scraper for three-phase horizontal screw pushing centrifuge, it is characterized in that the scraper includes fixed end 1 for being fixedly installed on the screw blade of centrifuge and scraper end 2 for scraping residue to avoid residue entering outlet pipe and causing blockage, the front end of the scraper end 2 is provided with inclined end 21 for reducing the gap between the scraper end 2 and the drum to improve the residue interception capacity;

[0018] By setting inclined end 21 at the front end of scraper end 2, the inclined end 21 at the front end of scraper end 2 is more matched with the drum, the gap between scraper end 2 and the drum is smaller, residue entering the outlet pipe of pushing centrifuge is more effectively prevented to cause outlet pipe blockage, residue entering water phase is effectively scraped, outlet pipe is not blocked, water is clearer and smoother, water pipe blockage caused by the rising of water level in the liquid tank of pushing centrifuge into oil phase is avoided to cause oil quality to decline, the service life of pushing centrifuge is improved, the frequency of shutdown maintenance is reduced, the water phase liquid level is stabilized during work, the fluctuation of water content in oil phase is reduced, the oil quality is stabilized, the overall oil extraction efficiency is improved.

[0019] In one embodiment, it also includes wear-resistant coating 3 arranged on scraper end 2 for increasing the wear resistance of scraper, and the wear-resistant coating 3 can be tungsten carbide coating for enhancing wear resistance;
