Abstract

The invention belongs to the technical field of construction machinery, and particularly relates to a quantitative powder loading system. The loading system comprises a powder weighting device which is used for feeding powder to a corresponding stirrer, and comprises a discharge opening for being communicated with the stirrer in a non-contact vibration isolation manner. The powder weighting device of the quantitative powder loading system comprises the discharge opening communicated with the stirrer in a non-contact vibration isolation manner, so that when in use, the powder weighting device is completely isolated from the stirrer, the vibration generated in the working process of the stirrer is prevented from affecting the precision of the powder weighting device and the problem of poor precision of the loading amount of an existing quantitative powder loading system is further solved.

Description

Powder quantitative feeding system

Technical field

The present invention relates to construction machinery equipment field, particularly relate to a kind of powder quantitative feeding system.

Background technology

In building field, usually can need the powders such as cement to mix to obtain the cement admixtures such as concrete or Stabilized Soil with material stirrings such as sandstone, flyash.Wherein concrete is most for house and bridge construction, and concrete quality directly affects intensity and the durability of corresponding building.Stabilized Soil is for road pavement, and the quality of Stabilized Soil is on the service life of road and time between overhauls(TBO) having larger impact.

No matter be concrete or Stabilized Soil, wherein the amount of institute's cement is all the important indicator that affects its performance, therefore, in concrete and Stabilized Soil production process, need to carry out strict control to the supply of its cement.Current cement feeding system majority is the form that adopts cement bin, conveying worm to be connected successively with weighing device.In process of production, conveying worm is directly fixed on the bottom of cement bin, in order to the cement in cement bin is outwards delivered to weighing device, weighing device is sent cement into mixer after weighing again, finally by mixer, cement and other mixing of materials is obtained to cement admixture.

In above-mentioned cement feeding system, because conveying worm is directly assemblied in cement bin bottom, it is direct feeding from cement bin, and cement in cement bin is because storage is larger and comparatively honest, very easily in cement bin, knot encircles, thereby can not enter into uniformly conveying worm, and then cannot guarantee the uniformity of the cement amount of sending into, reduce the quality of cement admixture; In addition, in above-mentioned cement feeding system, meausring apparatus is to be all directly located on corresponding mixer, in the process of mixer operation, the vibration producing can directly have influence on the precision of weighing device, and this also can cause the deviation of cement supply, reduces the quality of cement admixture.

Summary of the invention

The object of the present invention is to provide a kind of powder quantitative feeding system, to solve the poor problem of material loading accuracy of measurement of existing powder quantitative feeding system.

In order to address the above problem, powder quantitative feeding system of the present invention is by the following technical solutions: powder quantitative feeding system, comprise that described powder weighing device has the discharging opening for mixer noncontact vibration isolation conducting for send into the powder weighing device of powder to corresponding mixer.

Described powder weighing device is arranged at one independently on support.

Powder weighing device is weighing spiral feeder, and its feed end is hinged on described support, and discharge end is suspended on described support by weight sensor.

The discharge end of weighing spiral feeder is suspended on support by cantilever set on support, between described cantilever and support, is provided with brace.

The discharging opening place of dust weighing device is provided with the flexible vibration isolation cover for being connected with mixer.

Because the dust weighing device of this powder quantitative feeding system has the discharging opening for mixer noncontact vibration isolation conducting, therefore, when in use, dust weighing device and mixer can be isolated completely, thereby prevent the precision of the vibration effect dust weighing device that produces in the mixer course of work, and then solve the poor problem of material loading accuracy of measurement of existing powder quantitative feeding system.

Further, after powder weighing device is located at independently on support, the impact of the vibration that can avoid all devices around on powder weighing device, further guarantees its precision; After weighing spiral feeder is hinged on support, can reduce the impact of the junction of weighing spiral feeder and support on its precision, and angle that can adjustable screw Weighing feeder, make it reach optimum Working; Flexible vibration isolation cover can guarantee to block the vibration that mixer produces when powder weighing device is connected with mixer sealing.

Accompanying drawing explanation

Fig. 1 is the structural representation of the embodiment of powder quantitative feeding system.

The specific embodiment

The embodiment of powder quantitative feeding system, as shown in Figure 1, this powder quantitative feeding system comprises storage bin 11, transitional storehouse 12 and powder weighing device 13.

Storage bin 11 is powder warehouse, and its bottom is provided with outlet and in exit, is provided with valve (not shown), and valve is controlled by a switch, and what switch specifically adopted is LOAD CELLS 14.

Transitional storehouse 12 is located between storage bin 11 and powder weighing device 13, the import of transitional storehouse 12 is connected with the outlet of storage bin 11, outlet is connected with powder weighing device 13, when in use, first powder in storage bin 11 falls into transitional storehouse 12, and then by powder weighing device 13, it is exported from transitional storehouse 12, LOAD CELLS 14 as valve switch is connected with transitional storehouse 12, when the powder weight in transitional storehouse 12 drops to certain value, LOAD CELLS 14 orders about the valve open of storage bin 11, thereby to feed supplement in transitional storehouse 12.Movement and modularization setting for the ease of transitional storehouse 12 and powder weighing device 13, transitional storehouse 12 and powder weighing device are located at one independently on support 15, transitional storehouse 12 coordinates with support 15 by hook 16, for the ease of the maintenance to transitional storehouse 12, is also provided with maintenance platform 21 on support 15.

In the present embodiment, what powder weighing device 13 adopted is weighing spiral feeder, it is arranged on the support 15 of transitional storehouse 12 and is connected with transitional storehouse 12 by import, the port of export forms cantilever design and has for the discharging opening with mixer noncontact vibration isolation conducting, discharging opening place is provided with the flexible vibration isolation cover 22 for being connected with mixer, in addition, the entrance point of weighing spiral feeder passes through jointed shaft 17 hinge mounted on support 15, support 15 is provided with cantilever 18, the port of export of weighing spiral feeder is lifted on cantilever 18 by weight sensor 20, between cantilever 18 and support 15, be also provided with brace 19.

In other embodiment of powder feeding system, powder weighing device can also be located at another one independently on support, on the support that does not have a transitional storehouse, the discharging opening for mixer noncontact vibration isolation conducting of powder weighing device can also form by reducing discharging opening size, when in use, discharging opening is directly inserted in mixer but does not contact with mixer.
