Abstract
The utility model discloses without material-accumulating type screw feeder, it comprises sand storehouse (1), screw feeder body (2), imput shaft (3) and discharging opening (4), described screw feeder upper surface and sand bin discharge port external corresponding position are connected with triangle chute steel bracket, the surface of described triangle chute steel bracket is connected with steel plate chute (5), and described discharging opening is positioned at immediately below steel plate chute and area is less than the floor space of triangle chute steel bracket.The beneficial effects of the utility model change double helix into simple helix, only retain imput shaft, remove driven shaft, slow down delivery rate, drain from discharging opening through fully stirring after material enters screw feeder from Sha Cang, extend the length of the halt of material in screw feeder, avoid material to accumulate in operation below; The arc protuberance on steel plate chute surface contributes to reducing further material and enters speed in screw feeder, and the nil product realizing material is tired out, and avoids piling up in the double blade shafts puddle mixer of material below.
Description
Technical field
The utility model relates to screw feeder, particularly relates to without material-accumulating type screw feeder.
Background technology
Screw feeder is also screw feeder, and conveyor screw and slat conveyer, bucket carrier etc. belong to load transfer device together.The features such as have transport efficiency high, safe and reliable, structure is simple, the little and good looking appearance of complete function, good airproof performance, noise.Be widely used in various industrial sector, as building materials, electric power, chemical industry, metallurgy, coal, magnalium, machinery, light industry, grain and food service industry.Screw feeder carries out sense weight the material of process by crane span structure of weighing, to determine the weight of material on adhesive tape, rear-mounted Digital Speed Testing sensor, the running velocity of continuous gauging feeder, the pulse of this speed sensor exports the speed being proportional to feeder, speed signal sends into feeder controller together with weight signal, and the microprocessor in controller processes, and produces and shows cumulative amount/instant flow rate.This flow compares with setting flow, controls frequency converter and changes the actuating speed of feeder, the mass flow on feeder is changed by control instrument output signal, close to and remain on set feed flow, thus realize the requirement of dosing.Screw feeder should not carry material that is perishable, tough, easy caking, because these materials can be bonded on spiral when carrying, and do not move forward or formed at suspension bearing place the long-pending plug of material thereupon rotating, and make screw machine cisco unity malfunction.The technology application in tailing filling goaf, current down-hole is increasingly extensive, and bashing has earth's surface filling stirring system usually, Underground Backfilling Pipe Network, filter pipe net and the closed barricade intercepted towards filling dead zone passage.Filling process normally tailings feeds band conveyor by surge bunker (sand storehouse) bottom double helix feeder, and be delivered to double blade shafts puddle mixer, the stirring that adds water in puddle mixer is sized mixing, and enters filling dead zone by filling pipeline.But the shaft of double blade shafts puddle mixer to be crushed to death the technical barrier that cannot rotate at material level Gao Shiyi, has a strong impact on the normal operation of filling system.
Utility model content
The technical problems to be solved in the utility model is that existing screw feeder feed-type is direct, speed is fast, material level is too high kills shaft easily to make material bulk deposition in double blade shafts puddle mixer cause, and affects the normal work of filling system, provides a kind of without material-accumulating type screw feeder for this reason.
The technical solution of the utility model is: without material-accumulating type screw feeder, it comprises sand storehouse, screw feeder body, imput shaft and discharging opening, described screw feeder upper surface and sand bin discharge port external corresponding position are connected with triangle chute steel bracket, the surface of described triangle chute steel bracket is connected with steel plate chute, and described discharging opening is positioned at immediately below steel plate chute and area is less than the floor space of triangle chute steel bracket.
The improvement of such scheme is that the distribution of half portion horizontal uniform intervals is some on the surface has the arc of K/UP swell for described steel plate chute, and described arc protuberance interlocks spaced apart on the length direction of steel plate chute idol.
The beneficial effects of the utility model change double helix into simple helix, only retain imput shaft, remove driven shaft, slow down delivery rate, drain from discharging opening through fully stirring after material enters screw feeder from Sha Cang, extend the length of the halt of material in screw feeder, avoid material to accumulate in operation below; The arc protuberance on steel plate chute surface contributes to reducing further material and enters speed in screw feeder, and the nil product realizing material is tired out, and avoids piling up in the double blade shafts puddle mixer of material below.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the birds-eye view of Fig. 1;
In figure, 1, Sha Cang, 2, screw feeder body, 3, imput shaft, 4, discharging opening, 5, steel plate chute, 6, arc protuberance.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, 2, the utility model comprises sand storehouse 1, screw feeder body 2, imput shaft 3 and discharging opening 4, described screw feeder upper surface and sand bin discharge port external corresponding position are connected with triangle chute steel bracket, the surface of described triangle chute steel bracket is connected with steel plate chute 5, and described discharging opening is positioned at immediately below steel plate chute and area is less than the floor space of triangle chute steel bracket.The outlet of sand storehouse is positioned on same perpendicular line with discharging opening, and discharging opening is positioned at steel plate chute guarantee material directly can not enter discharging opening from Sha Cang.
Making step of the present utility model is as follows: 1, removed by traditional driven shaft, leaves imput shaft and pushes material.Lay down driven shaft tail end plain bearing and bearing seat during dismounting, the other end lays down bearing pin, then puts forward from Cang Ding; 2, the triangle chute steel bracket being welded with steel plate chute is made; 3, on conveyor screw, weld triangle chute steel bracket; 4, steel plate chute is arranged in triangle chute steel bracket.
In order to ensure that material can not be piled up in follow-up double blade shafts puddle mixer further, can at the steel plate chute some arc protuberances 6 having K/UP of half portion horizontal uniform intervals distribution on the surface, described arc protuberance is staggered spaced apart on the length direction of steel plate chute idol.Such first pair of material is shunted, and agglomerate material is spread out, is of value to follow-up stirring; Second pair of material slows down, and extends the length of the halt of material on steel plate chute.
Claims (2)
1. without material-accumulating type screw feeder, it comprises sand storehouse (1), screw feeder body (2), imput shaft (3) and discharging opening (4), it is characterized in that described screw feeder upper surface and sand bin discharge port external corresponding position are connected with triangle chute steel bracket, the surface of described triangle chute steel bracket is connected with steel plate chute (5), and described discharging opening is positioned at immediately below steel plate chute and area is less than the floor space of triangle chute steel bracket.
2. as claimed in claim 1 without material-accumulating type screw feeder, it is characterized in that described steel plate chute the distribution of half portion horizontal uniform intervals is some on the surface have the arc of K/UP swell (6), described arc protuberance interlocks spaced apart on the length direction of steel plate chute idol.
