Detailed Description

The utility model is further described in the following examples with reference to the accompanying drawings:

embodiment one:

a liquid dispensing station for easy installation, as shown in fig. 1 and 4, comprising:

the box body 1, other components are arranged in the box body 1, and the box body 1 serves as a shell of the liquid preparation station to protect the internal pipelines and equipment of the liquid preparation station;

a water inlet pipe 2 for accessing a tap water pipe, the tap water being introduced into the liquid preparation station through the water inlet pipe 2 and being used for mixing;

the oil inlet pipe 3 is used for being connected into the oil storage tank, and the oil inlet pipe 3 pumps oil in the oil storage tank into the liquid preparation station and is used for mixing;

an oil-water mixing pipe 4 for outputting the mixed liquid which is mixed in the liquid preparation station; and

a venturi mixer comprising a mixer body 5, the mixer body 5 having three joints.

The first joint 51 is connected with the water inlet pipe 2, the second joint 52 is connected with the oil-water mixing pipe 4, the third joint 53 is connected with the oil inlet pipe 3, and the first joint 51 and the second joint 52 are arranged in a straight line. The third joint 53 is provided on the side of the straight line where the first joint 51 and the second joint 52 are located, and is accessed from the side into the interior of the mixer main body 5.

A first solenoid valve 22 provided on a pipe of the water inlet pipe 2 and for cutting off or conducting the water inlet pipe 2;

a second electromagnetic valve 32 provided on a pipe of the oil feed pipe 3 and for intercepting or conducting the oil feed pipe 3;

a first flowmeter 21 provided on the pipe of the water intake pipe 2 and for acquiring the flow rate of the water intake pipe 2;

a second flowmeter 31 provided on the pipe of the oil feed pipe 3 and for obtaining the flow rate of the oil feed pipe 3;

and a controller configured to control the operation of the first solenoid valve 22 or the second solenoid valve 32 according to the value of the first flowmeter 21 or the second flowmeter 31. Because the lubricating oil or cutting fluid to be blended is prepared by water and oil according to fixed proportion, the opening degree of the electromagnetic valve is controlled by the flowmeter, so that the water quantity and oil quantity entering the mixer main body 5 can be effectively controlled, the controller can process the collected flow information of the first flowmeter 21 and the second flowmeter 31, and can dynamically adjust the first electromagnetic valve 22 or the second electromagnetic valve 32, so that the ratio of the water quantity and the oil quantity in the mixer main body 5 is kept near the preset proportion as much as possible, and the overlarge deviation of specific gravity of the oil and the water in the mixing process is avoided, and the quality of the prepared mixed fluid is improved.

The mixing ratio of the different components in the preparation process can be different due to the different mixing liquids required by the different devices, and the parameters of the first flowmeter 21 and the second flowmeter 31 can be adjusted through the controller, so that the oil amount and the water amount entering the mixer main body 5 can be controlled, and different mixing liquids can be prepared.

As shown in fig. 1 and 5, the inner end of the first joint 51 is provided with a first conical cavity 511, the conical head part of the first conical cavity 511 is provided with a first conical head hole 512, the first conical head hole 512 is arranged at one end of the first conical cavity 511 with smaller pipe diameter, and the first conical head hole 512 is led into the mixer main body 5. The inlet pipe 2 is connected with one end of the first conical cavity 511 with a larger pipe diameter, and when the water flow in the inlet pipe 2 enters the first conical cavity 511, the water flow can enter the mixer main body 5 after passing through the first conical head hole 512. Since the flow rate of the water flowing into the water inlet pipe 2 is constant and the pipe diameter inside the first conical cavity 512 is gradually reduced, as can be seen from the bernoulli continuity equation, when the water flows inside the first conical cavity 511, the flow rate of the water increases due to the gradual reduction of the pipe diameter, so that the water can be injected into the mixer body 5 at an extremely high flow rate. When the water flow speed is high, turbulence is formed in the water flow, so that the water and the oil are convenient to mix.

The inner end of the second joint 52 is provided with a second conical cavity 521, and the conical head portion of the second conical cavity 521 is provided with a second conical head hole 522. The first taper hole 512 and the second taper hole 522 are arranged opposite to each other, a certain gap 6 is arranged between the first taper hole 512 and the second taper hole 522, and the pipeline of the third joint 53 is communicated to the gap 6. Since the third joint 53 faces the gap 6, when the oil enters the inside of the mixer main body 5 through the third joint 53, the oil comes into direct contact with the high-speed water flow. When the high-speed water flow enters the region where the gap 6 is located through the first cone hole 511, the oil entering the interior of the mixer main body 5 from the third joint 53 is attracted to the direction of the gap 6 due to the low pressure of the high-speed water flow, so that the oil and the water are in rapid contact. At the same time, the high-speed water flow can swing the streamline inside the water flow, thereby forming turbulence. Turbulence causes irregular movement of the water flow, thereby facilitating mixing of the water and oil. The completed mixture enters the second conical chamber 521 through the second conical head 522 and exits the mixer body 5 through the oil-water mixing pipe 4 connected to the second joint 52.

Since the water inlet pipe 2 supplies water by means of the pipe pressure of tap water to be mixed with the oil in the oil inlet pipe 3, an additional water pump mechanism is not required. The venturi mixer can play roles in transforming pressure and guaranteeing stable mixing of water and oil, and compared with a water supply mode by adopting a water pump, the venturi mixer has the defect of low efficiency. But this product simple structure, low price need not the maintenance, and the installation of being convenient for can be quick set up on multiple different equipment.

It should be noted that if the length of the gap 6 is too small, the mixed liquid is not easy to flow into the second cone hole 522 because the high-speed water flow continuously flows out of the first cone hole 512, and the high-speed water flow has a smaller pressure, and the fluid with a higher pressure flows into the fluid with a smaller pressure, which is disadvantageous for extracting the mixed liquid from the mixer body 5.

If the length of the gap 6 is too large, the water flowing out of the first cone hole 512 at a high speed is difficult to determine the direction of the water flow due to irregular movement, and the water flow cannot smoothly enter the second cone hole 522 after being mixed, and may be accumulated in the mixer body 5, and even the mixed liquid may flow back.

The length of the gap 6 is thus typically controlled between 3 and 5mm, whereas in this embodiment the distance of the gap 6 is about 4mm.

As shown in fig. 1 and 5, the mixer body 5 is a pipe, in which a cone 7 is detachably installed, a second cone chamber 521 is formed inside the cone 7, and a second cone head hole 522 is formed on the tip of the cone 7. The cone 7 is screwed into the mixer body 5 by a screw, the cone 7 can be moved in the mixer body 5 by rotating the cone 7, and the size of the gap 6 can be adjusted by fine-adjusting the position of the cone 7 in the mixer body 5, thereby controlling the second cone 521 to suck the mixed liquid.

A liquid suction cavity 54 is formed between the outer side of the cone 7 and the inner wall of the pipeline of the mixer main body 5, the liquid suction cavity 54 is communicated with the third joint 53, and the liquid suction cavity 54 surrounds the outer side of the cone 7. The third joint 53 is connected to the side of the liquid suction chamber, and when a high-speed water flow enters the liquid suction chamber 54, the high-speed water flow contacts with oil entering the mixer body 5 from the side through the third joint 53, and under the interaction of two fluids with different flowing directions, the mixed liquid rotates around the outer side of the cone 7, so that the water and the oil are stably and efficiently mixed in the surrounding process.

The aperture of the second cone head hole 522 needs to be greater than or equal to the aperture of the first cone head hole 512 so that the water flow through the first cone head hole 512 smoothly passes through the second cone head hole 522 into the second cone chamber 521 after the water flow is completely mixed with the oil.

In this embodiment, the aperture of the second cone opening 522 is 0-3 mm larger than the aperture of the first cone opening 512.

As shown in fig. 1 and 5, a control cabinet 11 is formed in the box 1, and a controller is arranged on the control cabinet 11, so that the running state of the whole liquid preparation station can be controlled through the control cabinet 11. Thus, when the liquid preparation station is connected to different equipment, the proportion of water and oil in the mixed liquid of the liquid preparation can be adjusted through the control cabinet 11, so that the mixed liquid suitable for the different equipment can be produced by the liquid preparation station.

As shown in fig. 1 and 5, a display area 13 and function buttons 14 are provided on the door panel 12 of the case 1, and the flow, power, efficiency, current and voltage parameters are displayed on the display area 13, and the function buttons 14 include a power on, a power off and a scram button. Therefore, the working state of the liquid dispensing station can be clearly known without opening the door plate 12 in the use process, and the operation mode of the liquid dispensing station can be timely controlled.

Embodiment two:

the second solenoid valve 32 may be controlled to be opened by the controller to inject the liquid into the mixer main body 5 and to be closed after a certain time. After the mixing ratio inside the mixer main body 5 reaches the desired one, the second electromagnetic valve 32 is opened again, and the above-described flow is repeated. In this process, the first solenoid valve 22 is always kept open, and the controller only needs to regulate and control the second solenoid valve 32, so that stable and continuous oil can be ensured to be input into the oil suction cavity 54 to be mixed with water.

The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
