Description

Bubble removing device for weight volume measurement

Technical Field

The invention relates to the field of metering, in particular to a bubble removing device for measuring the volume of a weight.

Background

At present, the weight is mostly measured by a liquid static pressure method, namely a measuring method taking liquid density as a reference, and the volume of the weight is calculated by buoyancy force of the measured weight in liquid. Under the hydrostatic weighing method, the weight must be immersed in a liquid, however, when the weight is immersed in the liquid, air bubbles attached to the weight and the weight support can increase the buoyancy of the weight in the liquid in the measuring process, so that the measured volume value of the weight is larger, and a system error which cannot be corrected is formed. In order to solve the problems, manual wiping or removal of bubbles by means of a brush is commonly used, but the manual operation brings large workload to the measurement work, and the manual operation is easy to cause water temperature change, so the invention provides an electric weight bubble removal device to solve the defects of the prior art.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a bubble removing device for measuring the volume of a weight, which is used for removing bubbles attached to the weight.

The invention is realized by the following technical scheme:

a bubble removing device for weight volume measurement comprises a power supply controller, a fixed base plate, a motor, an impeller cavity, a water outlet pipe, a water inlet and a water outlet. The fixed bottom plate is fixed on the inner side of the wall of the liquid tank, the power controller is fixed on the outer side of the position, fixed to the fixed bottom plate, of the wall, the fixed bottom plate is fixedly connected with the motor, the motor is fixedly connected with one end of the impeller cavity, the other end of the impeller cavity is connected with the water inlet, an opening in the side wall of the impeller cavity is connected with one end of the water outlet pipe, and the other end of the water outlet pipe is set.

Preferably, one end of a hose is connected to the opening of the water outlet pipe, and the other end of the hose is a water outlet.

Preferably, the device also comprises a shock pad, wherein the shock pad is fixedly connected to the fixed bottom plate and is fixedly connected with the motor.

Preferably, a pressure control button is arranged on the power supply controller.

Preferably, the water outlet is duckbill-shaped.

Compared with the prior art, the bubble removing device has the following beneficial effects: the device utilizes rivers to clear away the bubble, clears away effectually, and is electric control, and the play water pressure is invariable. The bubble removing device is also provided with a hose which can move up and down and left and right, so that the position of the water outlet can be adjusted according to the position of the weight, and bubbles can be removed accurately. The bubble removing device is also provided with a shock pad, so that the vibration caused by the running of the motor can be reduced. The water outlet is designed into a duckbill shape, so that the flow velocity of water flow is high, the water spraying range is wide, the whole weight is covered in a region needing water spraying, and the bubble removing effect is better. Meanwhile, the device uses the liquid in the water container to keep the water temperature consistent, and reduces the error brought by the change of the water temperature to the measurement.

Drawings

Fig. 1 is a front view of a bubble removing device.

Fig. 2 is a rear view of the bubble removing device.

In the figure: 1. the device comprises a power supply controller, 2, a pressure control button, 3, a fixed base plate, 4, a motor, 5, an impeller cavity, 6, a water outlet pipe, 7, a water inlet, 8, a water outlet, 9, a hose, 10, a box wall, 11 and a shock pad.

Detailed Description

The technical scheme of the invention is clearly and completely described below by combining specific embodiments. It is obvious that the described embodiments are only some of the embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A bubble removing device for weight volume measurement is shown in figure 1 and comprises a power supply controller 1, a fixed base plate 3, a motor 4, an impeller cavity 5, a water outlet pipe 6, a water inlet 7 and a water outlet 8. The fixed bottom plate 3 is fixed on the inner side of the box wall 10 of the liquid box, the power controller 1 is fixed on the outer side of the position of the box wall 10 for fixing the fixed bottom plate 3, the fixed bottom plate 3 is fixedly connected with the motor 4, the motor 4 is fixedly connected with one end of the impeller cavity 5, the other end of the impeller cavity 5 is connected with the water inlet 7, the opening on the side wall of the impeller cavity 5 is connected with one end of the water outlet pipe 6, and the other end of the water outlet pipe 6 is arranged as the.

The whole device works as follows: the bubble removing device is fixed in a water tank filled with liquid and is positioned in liquid solution, the power supply controller 1 controls a power supply switch of the whole device, when the power supply controller 1 is started, the motor 4 starts to operate, the impeller is arranged in the impeller cavity 5, the motor 4 drives the impeller to rotate through the motor shaft, and after the impeller rotates, the solution flows in from the water inlet 7 and flows out from the water outlet 8. The solution that flows out has certain pressure, sprays on the weight to reach the mesh of the bubble of adhering to on the removal weight.

In this example, as shown in fig. 1, one end of a hose 9 is connected to an opening of the water outlet pipe 6, and the other end of the hose 9 is a water outlet 8. The hose can move up and down and left and right, so that the position of the water outlet is adjusted according to the position of the weight needing to remove bubbles.

Because the motor can produce the vibration when moving, shock pad 11 can reduce the vibrations that motor 4 brought to reduce the vibrations of incasement solution, reduce measuring error. As shown in fig. 2, a pressure control button 2 is arranged on the power supply controller 1, and the pressure of the water discharged from the water outlet is adjusted by the pressure control button 2, so that the water pressure of the water outlet is selected according to actual needs. As shown in fig. 1, the water outlet 8 is designed to be duckbill-shaped, so that the flow velocity of water is high, the water spraying range is wide, the whole weight is covered in the area where water needs to be sprayed, and the bubble removing effect is good.
