Description

Speed governing disk electronic scales

The utility model relate to a kind of dynamically down with grain, piece material particularly the high-temperature material below 300 ℃ by the dynamic metering device of setting the flow feeding.

At present, in the cement mill or agglomeration factory extensively adopt the dynamic metering device of belted electronic balance as high-temperature material, but, influenced the usability of measuring apparatus because belt descends greatly in be heated the back accuracy of measuring and durability.For this reason, Chinese patent ZL94210525.7 has invented a kind of with the speed governing disk electronic scales as the scale body such as speed governing feed disk, has overcome the defective of belt scale effectively.But also there are some problems in this scale on entire machine design, the one, the reductor input shaft of gear train is positioned at the below, because of having a large amount of lubricating oil, this place stores, and input shaft is in for a long time and runs up under the high temperature, must make the O-ring seal accelerated deterioration at this place, wearing and tearing cause leakage of oil, finally cause reductor to damage.The 2nd, an end of the material scraping plate on the feed disc face with the sliding sleeve kink on the disk vertical shaft that rotates.Often the malalignment because of vertical shaft and sliding sleeve installation causes wearing and tearing even damage in actual motion.

The purpose of this utility model is to overcome the weak point of above-mentioned speed governing disk electronic scales, and a kind of speed governing disk electronic scales that gear train and scraper are made improvements is provided.

The utility model is realized in the following way: this speed governing disk electronic scales comprises the feeder hopper of former speed governing disk electronic scales, by speed governing feed disk, the scale body that weighing base, fulcrum and frame are formed, the link code bar, pulling force sensor and controller, the gear train center of speed governing feed disk and disc centre are on same axis.Main improvement of the present utility model is, the motor shaft of gear train is connected with Hooks coupling universal coupling with the reductor input shaft, and motor is fixed on the frame, and reductor is fixed on the feed disk.Scraper on the feed disk adopts the revolution scraper, at the uniform some scrapers of cylinder outer wall, and revolution scraper buried bearing, it is bearing in scraping on the knife support of being connected with weighing base.The utility model makes the input shaft of reductor be in the top owing to improved the mounting means of gear train, has improved working environment, thereby has overcome the shortcoming of former deceleration input shaft leakage of oil easy to wear.Simultaneously, scraper is used the revolution scraper that is loaded on the fixed support instead, utilizes material produces in rotating operation on the disk thrust to rotate and reaches the purpose of scraper, has fundamentally solved the problem of former material scraping plate sliding sleeve rapid wear.

The utility model has the advantages that high temperature resistant, the wear-resisting problem of speed governing disk electronic scales that solved to high temperature grain, piece material dynamic measurement, and make the installation of motor and keep in repair more convenient, need not refinement determine the position when material scraping plate is installed, wearing quality is good, has prolonged the serviceable life of product.

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

With reference to accompanying drawing, this speed governing disk electronic scales comprises feeder hopper 1, by the scale body that speed governing feed disk 4, fulcrum 5, weighing base 11, frame 3 are formed, be fixed in the pulling force sensor 10 (controller is not shown) on weighing base 11 1 sides and the frame 3, and be fixed in the link code bar 12 of opposite side.The scale body is installed on the frame 3 by two fulcrums.Fulcrum is made of bearing 21 and bearing seat 22.Bearing seat 22 is fixed by bolts on the frame 3.The bearing center line of two fulcrums 5 and feed disk axes intersect and parallel with the radial centre lines XX of feeder hopper 1.One end of pulling force sensor 10 is arranged on the below of the empty material section of disk, and on the vertical line of two fulcrums, 5 lines of centres.Feeder hopper 1 is positioned at the top of disk 4, stray circle disk center.The central lines of its radial centre lines XX and disk 4.Revolution scraper 8 is made of cylinder 17 and the scraper 24 that is distributed on the outer wall, and scraper 24 is along the radial arrangement of cylinder.Projection and the feeder hopper radial centre lines XX on disk 4 is tangent for cylinder 17, and with disk 4 outer inscribes.Turn round scraper 8 buried bearings 19, be bearing in by splined shaft 14, spline housing 15 and scrape on the knife support 9.At the top of revolution scraper 8 and scrape and be provided with spring 16 between the knife support 9.Spring 16 is enclosed within on the splined shaft 14, is pressed in covering of bearing 19 by spring press-cover 18.Make the revolution scraper under spring action, be adjacent to the disk card automatically.Buncher 6 is fixed by bolts on the frame 3.Motor shaft is connected with Hooks coupling universal coupling 7 with reductor 13 input shafts.Reductor 13 is fixed by bolts on the disk 4, and its output shaft is connected with weighing base 11 centre wringing fits, and between disk 4 and weighing base 11 thrust ball bearing 23 is housed.In order to prevent that material from flowing into the reductor mounting hole, be provided with gland bonnet 2 in reductor 13 tops, be fixed on the disk 4.This scale also adopts tripod type frame 3, makes the transportation of scale body and installs more convenient.
