Abstract

The utility model discloses an electronic balance with a speed regulation disk, which can be used for compounding and measuring high-temperature granule and block materials. The balance body of the electronic balance is composed of a speed regulation feeding disk, a weighing seat, supporting points and a machine frame. A disk driving mechanism is fixed on the weighing seat; a feed hopper is deviated from the center of the disk; the supporting points are positioned at the two sides of the weighing seat; the line of centers of the supporting points is parallel to the radial central line of the feed hopper; a tension sensor is arranged on the vertical line of the line of centers of the two supporting points. The balance dispenses with additional feeding devices, having little dust and noise. The weighing precision can reach +-0.5-1%.

Description

Electronic balance with speed regulation disk

The utility model relates to a kind of speed governing disk electronic scales that is used for grain, piece material, particularly high temperature grain, piece proportioning materials and metering.

At present, in commercial production, use more high-temperature material scale that impulse flow meter and Chain plate scales are arranged during especially cement industry is produced.These scales all have jumping phenomena owing to structural reason during running, and must adopt the electro-vibrating feeder feeding, and dust and noise pollution are serious, and weighing precision is lower, generally only is ± 2.5%.

The purpose of this utility model is to overcome above-mentioned defective of the prior art, provide a kind of running steadily, need not add charging gear, and the higher speed governing disk electronic scales of weighing accuracy.

The utility model is achieved in that this speed governing disk electronic scales comprises feeder hopper, scale body, link code bar, pulling force sensor and controller.The scale body is made up of speed governing feed disk, weighing base, fulcrum and frame.The gear train of speed governing disk is fixed on the weighing base of disk below, and its center line is on the disk axis.Feeder hopper is arranged at the side on the disk, stray circle disk center, and the radial centre lines of feeder hopper overlaps with the disc centre line.Material scraping plate is arranged at the opposite side on the disk, and crossing with the radial centre lines of feeder hopper, its intersection point is at 1/2nd places of disc radius.The fulcrum of scale body is symmetricly set on the both sides of weighing base, and is bearing on the frame, the line of two dot center and disk axes intersect, and parallel with the feeder hopper radial centre lines.One end of pulling force sensor is connected on the weighing base, and its position is in the below of the empty material section of disk, and on the vertical line of the two fulcrum lines of centres, the other end is fixed on the frame.When disk rotates counterclockwise, material is from the feeder hopper charging, move 180 ° to the discharging opening discharge, only one side of something has material on disk, cause the imbalance of weighing mechanism, produce corresponding electric signal, import controller simultaneously with the motor speed signal by the pulling force sensor that is installed on the scale body, handle, computing, thereby draw the actual flow of material.

Advantage of the present utility model is and can directly passes through the feeder hopper feed from the feed bin bottom, need not other addition materials device, has obviously reduced the pollution of dust and noise.Because material steadily pulls out from feed bin, when having overcome the oscillating feeder feed to the impact of measuring apparatus.And structurally there are not Chain plate scales transmission polygon effect that is produced and the seismism of impacting flowmeter, so operate steadily.Simultaneously, what overcome that existing high temperature grain, piece material scale exist piles up irregular caused gravity shift phenomenon because of piece, pellet, thereby has improved weighing precision, can reach ± 0.5-1%.

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

With reference to accompanying drawing, this speed governing disk electronic scales comprises the feeder hopper 2 that connects spiral gate 1, by the scale body that speed governing feed disk 3, weighing base 13, fulcrum 14, frame 4 are formed, be fixed in the pulling force sensor 9 on weighing base 13 1 sides and the frame 4, and be fixed in the link code bar 10 of weighing base opposite side.Feeder hopper 2 is positioned at the top of speed governing feed disk 3, at least 300 millimeters of its center stray circle disk center, the central lines of the radial centre lines XX of feeder hopper 2 and disk 3.The opposite side of material scraping plate 8 on disk, crossing in 1/2 place and the radial centre lines of disc radius.The motor 11 of speed governing feed disk 3 is fixed by bolts on the reductor 12, and motor shaft is connected with shaft coupling 26 with the reductor input shaft.Reductor 12 is fixed by bolts on the weighing base 13.Speed reducer output shaft is connected with disk 3 centre wringing fits.For material can be discharged from material scraping plate 8 smoothly, be fixed on a cylinder 7 at the middle part of disk 3.The scale body is hung by two fulcrums 14 and is being provided with support foot 5 and is inspecting on the frame 4 of door 6.Fulcrum 14 is made of " X " shape reed 22.Reed is fixed by bolts on bearing 24 and the journal stirrup 23.Bearing 24 is fixed by bolts on the support plate 25, the side of support plate and frame 4 welding, and journal stirrup 23 is fixed by bolts on the weighing base 13.The line of two fulcrums, 14 center O and the axes intersect of disk 3 and parallel with the radial centre lines XX of feeder hopper 2.One end of pulling force sensor 9 is arranged on the below of disk 3 empty material sections, and on the vertical line of two fulcrums, 14 lines of centres.Be welded with sliding sleeve 20 on the material scraping plate 8, fixing with the locating shaft 19 that is loaded on the vertical shaft 15 on the disk and be connected on the support 21, support 21 is connected on the weighing base 13.Material scraping plate 8 usefulness springs 17, nut 16 are pressed on the disk 3.For adapting to the needs of high-temperature material, resistant to elevated temperatures sheet asbestos 18 is housed in the lower end of material scraping plate 8.
