Abstract
The utility model discloses a system for supplying an admixture for a concrete mixing plant, which comprise an admixture box (1), an admixture pump (2), an admixture scale (9), and a refined weighing box (7) arranged above the admixture scale (9), wherein a fluid valve (4) is arranged on a refined weighing outlet pipe (3) at the lower part of the refined weighing box (7) and connected with the admixture scale (9), a main inlet (6) is formed on the side surface of the refined weighing box (7) and connected with the admixture box (1) through the admixture pump (2), a main outlet (8) is formed at the top of the refined weighing box (7) and connected with the admixture scale (9), and an accurate adjustment valve (5) between the refined weighing box (7) and the fluid valve (4) is arranged on the refined weighing outlet pipe (3). The system for supplying the admixture for the concrete mixing plant has the advantages of higher measuring accuracy, simple structure, and reliable performance.
Description
Technical field
The utility model relates to a kind of concrete batch plant, particularly relates to a kind of concrete batch plant for the additive system.
Background technology
Additive is one of important source material of ready-mixed concrete, and every mixing plant is produced concrete additive batching and do not waited to tens kilograms from several kilograms of every fillings, its measuring accuracy according to national standard must reach ± 1%.For satisfying for the additive required precision, the existing general practice is to use for reference the concrete batch plant water system.This water system includes water pump and water scale, the top of described water scale is provided with replenishing water tank of water, replenishing water tank of water water main inlet port and main delivery port all are arranged on the top of replenishing water tank of water, water main inlet port is communicated with water pump, main delivery port leads to the water scale, the bottom of water supply tank also is provided with water supplement port, and water supplement port is communicated with the water scale through filling pipe, and filling pipe is provided with fluid valve.The main entery and delivery port that passes through replenishing water tank of water during system works earlier supplies water to the water scale, satisfies the required precision of supplying water thereby carry out the less accurate water supply of flow by filling pipe again.But the main import and export of water supply tank is at same horizontal level, and the liquid that water pump stops in the trunk line of back can not in time be dammed and recoil, and influences measuring accuracy and continue to rush at the water scale.Constant filling pipe diameter can not be regulated flow, and when the little weighing of additive, the filling pipe flow is excessive relatively, and relative error is excessive, does not reach the measuring accuracy requirement.
The utility model content
Technical problem to be solved in the utility model provides the higher concrete batch plant of a kind of measuring accuracy for the additive system.
In order to solve the problems of the technologies described above, the concrete batch plant that the utility model provides is for the additive system, comprise the additive case, the additive pump, additive scale and the smart scale case that is arranged on additive scale top, the smart scale drain pipe of smart scale lower box part is provided with a fluid valve and is connected with the additive scale, the side of described smart scale case is provided with a main import, described main import is connected with described additive case by described additive pump, it is characterized in that: the top of described smart scale case is provided with a primary outlet and is connected with described additive scale, and described smart scale drain pipe is provided with the accurate adjustment valve that is between described smart scale case and the described fluid valve.
The concrete batch plant that adopts technique scheme is for the additive system, in smart scale case side main import is set, the top is provided with primary outlet, and the pipeline that the liquid after the additive pump stops in the trunk line can be made progress at once dams and recoils, can not continue to rush at the additive scale, guarantee the accurate of weighing.The utility model also was provided with the accurate adjustment valve before the fluid valve on the smart scale drain pipe, regulate the smart flow that claims, satisfied the required precision of the little weighing of additive.
In sum, the utility model is that a kind of measuring accuracy is higher and simple in structure, the concrete batch plant of dependable performance supplies the additive system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the side of smart scale case 7 is provided with a main import 6, main import 6 is connected with additive case 1 by additive pump 2, the top of smart scale case 7 is provided with a primary outlet 8 and is connected with additive scale 9, smart scale case 7 bottoms are connected with additive scale 9 by smart scale drain pipe 3, smart scale drain pipe 3 is provided with a fluid valve 4 and accurate adjustment valve 5, and accurate adjustment valve 5 is between smart scale case 7 and the fluid valve 4.
As shown in Figure 1, the pipeline that the liquid after additive pump 2 stops in the trunk line can be made progress at once dams and recoils, and can not continue to rush at additive scale 9, has guaranteed the accurate of weighing.Before the fluid valve 4 on the smart scale drain pipe 3, accurate adjustment valve 5 is set, regulates the smart flow that claims, satisfy the required precision of the little weighing of additive.
