Abstract

The utility model relates to a chain plate balance, which is used for continuously weighing flowing materials. The chain plate balance is composed of a chain plate conveyer, a balance body, a tension sensor and an electronic metering control system, wherein, the chain plate conveyer is hung on the balance body, and the scale body is provided with two pairs of knife plates (8) which are arranged between an upper and a lower chain belts on both sides of the chain plate conveyer. The balance body adopts a weighing mechanism which is supported by a knife edge and is connected with a force arm in parallel. The chain plate balance can be used for continuously metering high-temperature bulk materials below 400 DEG C, and can effectively eliminate the four-corner errors and guarantee the metering accuracy to be within (+/-) 1%.

Description

Chain plate scales

The utility model relates to a kind of electronic weighing instrument of consecutive weighings flowable materials.

The bulk material that in the past needed to measure continuous conveying generally adopts belted electronic balance, and this can meet the demands for the normal temperature material.If but be used for the high-temperature material of weighing more than 150 ℃, and burn out for avoiding adhesive tape, must on adhesive tape, fetch water, not only influence measuring accuracy, and worsened environment, this is the problem of not properly settling as yet at present.

Task of the present utility model provides the Chain plate scales of the high temperature bulk material of a kind of energy continuous measurement below 400 ℃.

The utility model is achieved in that Chain plate scales is made up of chain scraper conveyor, scale body, load sensor and electrometer amount control system.Chain scraper conveyor is hung on the scale body.The scale body has 2 pairs of knife plates, is arranged on the chain scraper conveyor both sides up and down between the chain belt.Emphasis knife and fulcrum knife are housed on the knife plate, and the frame of chain scraper conveyor is hung on the emphasis knife, and the fulcrum knife is suspended on support bracket fastened below.About connect with crossbeam respectively between the two pairs of knife plates, an end of crossbeam stretches out outside the machine, each fixes a symmetrical arm of force in its end, two arm of forces are parallel to joint efforts on the cutter bearing, the cutter bearing of making a concerted effort is hung the lower end at pulling force sensor.By above-mentioned physical construction, make 4 gravity that knife plate bore be combined into 2 and make a concerted effort by crossbeam, the arm of force by two parallel connections is combined into one with joint efforts again, is delivered on the pulling force sensor at last.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A-A vertical view of the present utility model;

Fig. 3 is the knife plate wiring layout;

Fig. 4 is the cutter holder structure figure that makes a concerted effort.

Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.

Chain scraper conveyor comprises chain belt (1), gearing (2) and frame (3).The scale body is made up of hook (4), the cutter bearing (5) of making a concerted effort, the arm of force (6), crossbeam (7), knife plate (8), last hanger (9), following hanger (10), suspension rod (11) and fixed support (12).Chain scraper conveyor is hung on the little axle (17) of 4 following hangers of scale body (10) by 4 hooks (4) that are cemented in frame (3).The vertical section of little axle (17) is made arcs of recesses, is not subjected to displacement when hanging with the assurance hook.Totally 4 of knife plates (8) are made of knife fixed head (18), emphasis knife (15) and fulcrum knife (16), and two knives are installed on the knife fixed head (18).Each following hanger (10) is furnished with a cutter and holds (14), holds (14) by cutter and is suspended on the emphasis knife (15).Fulcrum knife (16) is bearing in 4 cuttves of going up hangers (9) respectively and holds on (14), and last hanger (9) is then hung below in fixed support (12) by suspension rod (11).About connect with crossbeam (7) respectively between two pairs of knife plates (8), crossbeam (7) passes outside the machine from the interband of chain up and down of chain mat machine.Each fixes a symmetrical arm of force (6) in the end of beam, and cutter bearing (5) is in parallel two arm of forces by making a concerted effort.The cutter bearing (5) of making a concerted effort is held (19) by interior hanging basket (20), outer hanging basket (21), bearing pin (22) and cutter and is formed.2 cuttves hold (19) be installed in respectively can around the interior hanging basket (20) of bearing pin (22) swing and outside on the hanging basket (21).Bearing pin (22) is hung the lower end in pulling force sensor (13).Cutter holds (19) by rivet (25) and hanging basket riveted joint, can be around the axis rotation of rivet.Two arm of forces (6) are bearing in cutter by the knife (23) that is contained in its end and hold on (19).Take the structure of this expansion bearing can guarantee more reliably that the power that passes to the cutter bearing of making a concerted effort from 2 arm of forces vertically is delivered on the pulling force sensor (13).Pulling force sensor (13) is fastened on the fixed support (12) by bearing pin (23) and annular bearing (24).

The utility model uses the feeding equipment of chain scraper conveyor as electronic scales, therefore can be used for the block or granular high-temperature material of continuous measurement below 400 ℃.Simultaneously since all fulcrums, force, emphasis all adopt the knife edge bearing structure, and adopted the arm of force in parallel mechanism, thereby can improve measuring accuracy, eliminate position error effectively, guarantee that measuring accuracy is in ± 1%.
