Description

Technical Field

[0001] The invention belongs to the field of oil defoaming equipment design, and in particular relates to a pre-cooling defoaming device for a liquid particle counter. Background Art

[0002] In hydraulic lubrication systems, the degree of oil contamination directly affects the performance and reliability of the hydraulic system. This requires that the oil contamination level must be controlled within the system's permitted range. Liquid automatic particle counters that work on the principle of light obstruction have become a widely accepted primary tool for measuring oil contamination.

[0003] However, in the process of detecting the lubricating oil, the equipment for detection after the oil is exported needs to be defoamed first. The Chinese invention patent defoaming oil filter and hydraulic oil tank for oil defoaming in the prior art, application number: 202110841458X, describes a structure that also uses defoaming by increasing its surface area. However, in actual use, it cannot meet the situation when the oil fluidity is strong during the process, and the bubbles do not follow when the oil falls. And its defoaming method, when applied to detection, is bound to greatly reduce the amount of oil, thereby affecting the detection structure, and thus cannot meet the requirements of the prior art. Summary of the invention

[0004] The purpose of the present invention is to provide a pre-cooling defoaming device for a liquid particle counter to solve the problem in the prior art that the defoaming process affects the subsequent detection results and the reflux of bubbles in the oil.

[0005] The present invention provides a pre-cooling and defoaming device for a liquid particle counter, which includes a storage box and a defoaming box connected at the bottom, and a top cover is installed at the upper end of the two;

[0006] The defoaming box has an oil cavity, a defoaming structure is installed at the upper end of the oil cavity, a funnel-shaped leakage port is provided in the middle of the lower end of the oil cavity, and the bottom of the leakage port is connected to the storage box through a butterfly valve and a pipeline; a heat-conducting ring and a heat-conducting aluminum plate are arranged from the inside to the outside around the leakage port, and an electric heating plate is arranged at a certain interval on the lower side of the heat-conducting aluminum plate; a plurality of pairs of cooling pipes penetrating the oil cavity are also provided on the defoaming box, and each pair of cooling pipes are connected at the inner end to form a loop;

[0007] The defoaming structure has a plurality of array structures penetrating the cavity up and down, and the contact surface with the oil is rough.

[0008] Advantageously, the pipeline comprises a connecting pipe and an auxiliary pipe, both ends of the auxiliary pipe are respectively connected to a connecting pipe, and a liquid pump is provided in the auxiliary pipe.

[0009] Advantageously, the auxiliary tube also has a through cavity, presenting a needle-tube-like structure.

[0010] Advantageously, a buffer chamber is provided between the butterfly valve and the pipeline.

[0011] Advantageously, the defoaming structure adopts a honeycomb structure.

[0012] Advantageously, the cavity interface of the honeycomb structure is polygonal or circular.

[0013] Advantageously, a storage compartment is provided in the storage box.

[0015] Advantageously, the top cover has a threaded hole on one side of the defoaming box for installing an injection pipe or a vacuum pump pipe.

[0016] Advantageously, a two millimeter gap is left between the electric heating plate and the heat-conducting aluminum plate.

[0017] Beneficial effects: The bubbles on the surface of the oil can be filtered with a high probability, and the defoaming structure can be cooled to achieve the stability of the bubbles in the oil, while greatly reducing the impact of bubbles on subsequent detection structures. The auxiliary heating after the oil is passed into it helps to increase the fluidity of high-concentration oil, and the accelerated vortex is achieved when heated to achieve better collection of solid particles during use. At the same time, its fluidity is increased to accelerate the floating effect of bubbles. The above method helps to enhance the elimination of bubbles during use. In addition, the cooling method used helps to retain bubbles, and combined with the vacuum setting, a large number of bubbles are broken, thereby reducing the loss of oil.

[0026] Embodiment 1:

[0027] like Figure 1-3 The pre-cooling and defoaming device for the liquid particle counter shown includes a storage box 1 and a defoaming box 2 fixedly installed on one side thereof. The storage box 1 and the defoaming box 2 are interconnected at the bottom by a connecting pipe 12 and an auxiliary pipe 14.

[0028] A storage compartment 11 is provided in the storage box 1 .

[0029] The defoaming box 2 has an oil cavity therein, which is connected to a cooling pipe 22 passing through the defoaming box 2; cooling water is introduced into the oil cavity through the cooling pipe 22. A defoaming structure is arranged on the upper side of the oil cavity, and a heating component is arranged on the lower side.

[0030] The oil in the oil cavity is heated by a heating assembly, which includes: an annular heat-conducting aluminum plate 23 and an annular electric heating plate 24. The heat-conducting aluminum plate 23 is located at the outer edge of the lower side of the annular cavity, and an electric heating plate 24 is provided on the lower side of the heat-conducting aluminum plate 23. The electric heating plate 24 is installed on the periphery of the heat-conducting ring 25, and a two-millimeter gap is left between the electric heating plate 24 and the heat-conducting aluminum plate 23. A heat-conducting ring 25 is provided at the center of the heating assembly, and heat is conducted to the liquid leakage port 26 of the defoaming box 2 through the heat-conducting ring 25, which is more conducive to its heat conduction efficiency.

[0031] A liquid leakage port 26 is provided at the inner center of the defoaming box 2 .

[0032] The cooling pipes 22 passing through the inner and outer sides of the defoaming box 2 are grouped in pairs, and a surrounding pipe is installed at the inner end, which forms a complete loop for the two cooling pipes 22 in each group. The cooling pipes 22 are used to pass cooling water to effectively cool the internal oil.

[0033] Among them, the cooling tube 22 can also play the role of auxiliary flushing in actual use. The corresponding part of the volatile liquid detection chamber maintains a closed environment, and when the heating chamber is stirred to increase its volatility, it is not easy to heat. Instead, the equipment is placed in a low temperature environment, and then the cooling tube 22 is spirally injected into the liquid to be tested to reduce the possibility of its volatilization. At the same time, due to the spiral flushing, the liquid rotates inside, thereby enhancing its detection results.

[0034] The leakage port 26 is used to collect solid particles in the oil during use, so as to avoid the accumulation of solid particles on the outside during use. The solid particles are more likely to gather in the middle, thereby avoiding the loss of the medium to be measured in the oil during the defoaming of the oil to be measured, which affects the measurement structure and further enhances the accuracy of the detection. The lower side of the leakage port 26 is connected to the connecting pipe 12.

[0035] The auxiliary tube 14 includes a liquid pump 15, and a through cavity 16 is provided on the auxiliary tube 14 on both sides of the liquid pump 15. The through cavity 16 is a needle-shaped structure. The needle-shaped structure of the through cavity 16 facilitates effective extraction of the part during use and facilitates observation of the internal oil condition.

[0036] The storage box 1 and the defoaming box 2 are provided with a top cover 3 on the upper surface, and the top cover 3 is provided with a threaded hole 31 at the position corresponding to the defoaming box 2. The threaded hole 31 is used to install the injection pipe or the vacuum pump pipe. After the two sets of threaded holes 31 are set, they need to be used in coordination when used. First, when injecting oil into the interior, it is necessary to control the closing of another threaded hole 31, and when vacuuming the interior, it is necessary to close the corresponding other threaded hole 31. This operation helps the equipment to operate effectively.

[0037] Protective strips 13 are provided at corresponding edges of the upper surfaces of the storage box 1 and the defoaming box 2 to prevent leakage during use.

[0038] Embodiment 2:

[0039] On the basis of the first embodiment, the defoaming box 2 also includes: a buffer chamber 28, which is located at the lower side of the leakage port 26 and is used to discharge the oil after defoaming, and a butterfly valve 27 is arranged on the top pipeline passage of the buffer chamber 28, and the output end of the buffer chamber 28 is interconnected with the auxiliary pipe 14 through the connecting pipe 12.

[0040] Embodiment three:

[0041] The defoaming structure is a honeycomb structure 21. When in use, its surface cooling efficiency is increased, and when it is set to a rough surface, its bubble adsorption effect is more conducive to the adsorption of small bubbles when in use.

[0042] Embodiment 4:

[0043] like Figure 4 and Figure 5 As shown, the defoaming structure has an array of cavities inside, which are connected from top to bottom, and the contact surface between the defoaming structure and the oil is rough. The interface of the cavity unit can be polygonal or circular.

[0044] Among them, when the cylindrical inner cavity 29 is in use, its surface cooling efficiency is close to that of the honeycomb, and when it is set to a rough surface, its bubble adsorption effect is more conducive to the adsorption of large bubbles during use.

[0045] Working principle: When the defoaming structure is set, the bubbles on the surface of the oil can be filtered with a high probability, and the temperature is reduced in the defoaming structure to achieve the stability of the bubbles in the oil, while greatly reducing the impact of bubbles on subsequent detection structures. The auxiliary heating after the oil is passed into it helps to increase the fluidity of high-concentration oil, and when it is heated, it accelerates the vortex to achieve better collection of solid particles during use, while increasing its fluidity and accelerating the floating effect of bubbles.
