Description

Water weighing device for concrete mixing plant

Technical Field

The utility model belongs to the technical field of concrete mixing plant auxiliary assembly, especially, relate to a concrete mixing plant water weighing device.

Background

The weighing system is one of the important components of the automatic production of the concrete mixing plant, is a key component influencing the quality of concrete and mainly comprises three parts, namely aggregate weighing, powder weighing and liquid weighing. Water is used as a basic component for weighing liquid, the quality of concrete is directly influenced by the proportion and the batching precision of the water, and particularly the slump of the concrete is greatly influenced. At present, the water scale structure for the stirring station generally adopts a siphon type mode and a self-flowing type mode, but has certain defects: the siphon water scale is characterized in that water in a high-position weighing hopper enters a low-position stirrer by utilizing a siphon principle, the water discharge action is triggered by starting a water pump, but the water scale in the form has no on-line real-time water retaining function, the water in the weighing hopper cannot be completely discharged due to the siphon structure, and a small amount of water remains; the self-flow water scale discharges water into the stirrer by utilizing the self-weight of the water in the weighing hopper, and the water outlet end is provided with a pneumatic butterfly valve, so that the online real-time water retaining function can be realized.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to improve the not enough of prior art and provide a concrete mixing plant water weighing device, realized that the online of mixing plant water balance detains the water function, can pressurize fast again and unload water, both improved the efficiency of unloading, solved the armful of axle phenomenon of concrete again.

The utility model aims at realizing like this, a concrete mixing plant water weighing device, weigh the bucket body including water, its characteristics are the water outlet body that the lower part of water weighing bucket body is the infundibulate binding off, the internal vertical fixed breakwater that is equipped with of delivery port, evenly distributed has bar weighing sensor more than three on the water weighing bucket body lateral wall, all bar weighing sensor are located same horizontal plane, the water outlet body is fixed with first takeover, first takeover is taken over through pneumatic butterfly valve connection second, the second is taken over and is taken over through the rubber sleeve with the third and be connected, the rubber sleeve suit is fixed with the steel pipe, the length of steel pipe is less than the length of rubber sleeve, the third is taken over and is connected through the force (forcing) pump and mix the cover drain pipe.

Compared with the prior art, the utility model has the following characteristics of showing and positive effect: the water outlet of the water weighing bucket body is internally provided with the vertical water baffle plate, so that the water vortex is prevented from being formed in the water discharging process, and the water cannot be uniformly and quickly discharged, so that the water discharging amount is not uniform and the water discharging time is prolonged; more than three symmetrical weighing modes are adopted, so that the water weighing bucket body is more stable and the weighing is more accurate; the pneumatic butterfly valve connected with the water outlet body can realize the online water buckling function of the mixing plant under the control of an external electrical control system, and is more intelligent and humanized; the second connecting pipe and the third connecting pipe are in flexible connection through the rubber sleeve, the water weighing device on the upper portion of the flexible connection can work normally, and the steel pipe arranged in the rubber sleeve can prevent water discharging difficulty caused by extrusion of the rubber sleeve due to suction force of the water pump when the pressure pump discharges water. The pressure pump is adopted, so that the rapid pressurization and water discharge can be realized, the water entering the water discharge pipe of the mixing drum cover is pressurized and discharged, the water discharge time can be reduced, the water discharge efficiency is improved, the water can be discharged into the mixer, and simultaneously, the high-pressure flushing is carried out on two mixing shafts of the mixer, so that the shaft holding phenomenon of concrete is solved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a top view of fig. 1.

In the figure: 1. the water weighing bucket comprises a water weighing bucket body, 2 a bar-shaped weighing sensor, 3 a water baffle, 4 a first connecting pipe, 5 a pneumatic butterfly valve, 6 a second connecting pipe, 7 a rubber pipe, 8 a steel pipe, 9 a water outlet body, 10 a third connecting pipe, 11 a pressure pump, 12 a mixing barrel cover drain pipe.

Detailed Description

A water weighing device for a concrete mixing plant, referring to fig. 1 and 2, a water weighing hopper body 1 is a circular cylinder, the lower part of the water weighing hopper body 1 is a funnel-shaped closed water outlet body 9, a vertically fixed water baffle 3 is arranged in the water outlet body 9, and the water baffle 3 divides the space in the water outlet body 9 into two parts so as to prevent water from forming a water vortex in the water discharging process and preventing water from being discharged uniformly and quickly, so that the water discharging amount is not uniform and the water discharging time is prolonged; more than three bar-shaped weighing sensors 2 are uniformly distributed on the outer side wall of the water weighing bucket body 1, all the bar-shaped weighing sensors 2 are located on the same horizontal plane, the embodiment takes the three bar-shaped weighing sensors 2 as an example, the three bar-shaped weighing sensors 2 are uniformly distributed on the outer side wall of the water weighing bucket body 1 by adopting a support type structure, and the three bar-shaped sensors 2 are located on the same horizontal plane, so that the water weighing bucket body 1 is more stable and more accurate in weighing; a first connecting pipe 4 is fixed at the outlet of the water outlet body 9, the first connecting pipe 4 is connected with a second connecting pipe 6 through a pneumatic butterfly valve 5, a rubber sleeve 7 is connected between the second connecting pipe 6 and a third connecting pipe 10, and the rubber sleeve 7 is flexible, so that a flexible connection mode is formed between the second connecting pipe and the third connecting pipe; the steel pipe 8 is arranged in the rubber sleeve 7, the length of the steel pipe 8 is smaller than that of the rubber sleeve 7, and the steel pipe 8 is not in contact with the second connecting pipe 6 and the third connecting pipe 10, so that the flexible connection is not influenced, and the phenomenon that the rubber sleeve 7 is extruded together due to the suction force of the pressure pump 11 when the pressure pump 11 discharges water can be prevented, and the water discharging is not smooth; the third connecting pipe 10 is connected with a mixing barrel cover drain pipe 12 of the mixing main machine through a pressure pump 11, the pressure pump 11 can realize rapid pressurization and water discharge, and the water entering the mixing barrel cover drain pipe 12 is pressurized and discharged, so that the water discharge time can be reduced, the water discharge efficiency can be improved, the water can be discharged into the mixing machine, and simultaneously, the two mixing shafts of the mixing machine are washed at high pressure, and the shaft holding phenomenon of concrete is solved.
