Description

FIELD OF TECHNOLOGY

The invention relates to the field of production of lubricants, namely, to a device for initiating cavitation and the process of “cold” mixing of base oils and additives for the production of lubricants - commercial oils and cutting fluids.

BACKGROUND

A device for mixing oils, disclosed in WO 2008/016937 A2, publ. 02/07/2008. The known device contains means for supplying oil and liquid to the storage tank, a pump for pumping oil and liquid, a cavitation column and a drain channel for outputting the obtained mixed oil.

A disadvantage of the known device is that the device mixes finished products with each other, but is unable to mix base materials and additive packages in order to obtain finished lubricants (technical oils) and cutting fluids (coolant). An obvious disadvantage is that this device is capable of mixing exclusively at high temperature, i.e. components must be preheated to + 60C.

The closest analogue of the claimed utility model is a device for preparing liquid mixtures disclosed in RU 131310 U1, publ. 08/20/2013. The device disclosed in the closest analogue contains a housing inside which there are plates with holes perpendicular to the flow of the medium, while the equivalent diameter of the holes in each subsequent plate along the stream is smaller than in the previous one. In this case, an additional plate made of a solid porous material is installed behind the last plate in the flow direction.

The disadvantage of the closest analogue is the implementation of the cavitation process when heating the mixture to mix and the inability to mix complex components to obtain cutting fluids (coolant). A clear difference is the absence of planar channels, as well as the combination in the solution of planar and cylindrical channels, which allows to obtain a high level of mixing. The obvious difference is that the module for “cold” mixing is / is located inside the tank (device for “cold” mixing), which also allows to obtain a higher level of homogenization.

DISCLOSURE OF A USEFUL MODEL

The technical result of the utility model is to increase the homogeneity of homogenization, dispersion and reduce energy consumption when mixing base oils and various additive packages.

The specified technical result is achieved due to the fact that the device for “cold” mixing of lubricants contains a container inside which is located the module of “cold” mixing, comprising a housing, an input unit for the mixed components, an output unit for the mixed components, while at least two all-metal blocks containing through cylindrical and planar channels, moreover, an active mixing zone is located between adjacent blocks, and the container and module are “cold” th "mixing interconnected conduit having one end connected to the lower part of the container, and the other - to the input nodes of the mixed components.

In each block there are four planar channels in which a narrowing along the height of the channel from the beginning of the channel along its length corresponding to% of the channel length is provided.

The plane channels in each block are located evenly relative to each other at a distance of 5-7 mm from the edge of the block.

narrowing (decreasing the height of the channel) is provided for its length, after narrowing the channel expands to the end of its length (to the height corresponding to the beginning of the channel), while narrowing along the length of the channel of the corresponding

its length, the height of the channel is 0.5-4 mm

The plane channels (2) in each block (1) are located evenly relative to each other at a distance of 5-7 mm from the edge of the block (1).

Cylindrical channels (3) in each block (1) are located evenly relative to each other inside the perimeter formed by planar channels (2).

The cylindrical channels (3) are made with a constant diameter.

In the first block (1), at least four cylindrical channels (3) are made, preferably at least eight four cylindrical channels (3). As a maximum, at least ten cylindrical channels (3) are made in the first block (1). The diameter of the cylindrical channels (3) in the first block is 1.5-1.7 mm.

In subsequent blocks (1), two more cylindrical channels (3) are made than in the previous one.

In subsequent blocks (1), cylindrical channels (3) are made having a smaller diameter than in the previous one. In subsequent blocks (1), the diameter of the cylindrical channels (3) decreases by 0.2-0.25 mm from the previous block (1).

At the inlet of the assembly (5) of the input of the mixed components, a pressure sensor (7) is located.

At the output of the node (6) output of the finished product is a viscometer (8).

Module (9) has its own automation unit and software.

A device for "cold" mixing of lubricants works as follows. In the container (10) of the device for “cold” mixing of lubricants, a module of “cold” mixing is placed, which is fixed at the end of the pipeline (13), so that the assembly (5) for introducing the mixed components is connected to the pipeline (13) . The other end of the pipeline (13) is connected to the lower part of the tank (10), while a pump (11) is located in the pipeline. Then they carry out the filling of the container of the components for mixing, containing in appropriate quantities (see table 1), for example, two base oils Bryshtok and SN500 and two additives ADD1 and ADD2 PPD. After filling the tank by 30%, the strain gauge (12) monitors the tank filling level (10), the software starts the operation of the cold mixing module (9) in pre-mixing mode, at which the pump is switched on, which operates at 50% of the maximum power and passes through the module (9) "cold" mixing the components for 10-15 minutes at a temperature of 20-30 ° C for uniform distribution of additives throughout the volume of base oils. In this mode, the software monitors the operation of frequency converters in the range of 0-30 Hz to control the speed of the pump motor (11).

After filling the container (10) of all components in the required volume, the strain gauge sensor (12) signals the end of loading and the software switches the operation of the cold mixing module (9) in the main mixing mode, at which the feed rate of the components and the pressure in the zones increase (4) active mixing in the module (9) "cold" mixing. During the operation of the cold mixing module (9) in the main mixing mode, the pump supplies the components to the pipeline (13) to the input node (5) of the input of the mixed components of the cold mixing module (9), then the components flow at high speed through cylindrical (3 ) and planar (2) channels enter the active mixing zone (4) (cavitation chamber) in which the collapse of billions of bubbles occurs, which leads to the formation of many microexplosions capable of mixing organic complexes at the molecular level. After zone (4) of active mixing, the flow of components at high speed passing through the cylindrical (3) and planar (2) channels exits through the outlet the assembly (6) of the output of the mixed components of the cold mixing module (9) and enters the tank (10) . Thus, the process of mixing the components takes place in a closed loop: a container (10) - module (9) of “cold” mixing until the viscometer sensor gives a signal about the homogeneity of the mixture and stabilization of viscosity. After the end of the main mixing mode, the software automatically stops the pump (11) and the finished product is pumped to the storage tank or immediately fed to the packaging line of the finished product, or a sample is taken for analysis. To ensure the desired flow rate and the required pressure in the zones (4) of active mixing, the software adjusts the settings of the frequency converters in the range of 0-50 Hz to control the speed of the pump motor (11). A pressure sensor and a viscometer allow the software to track the necessary signals and adjust the speed of the pump motor, creating the necessary fluid flow rate to ensure an effective cold mixing process.

The presence of cylindrical (3) and planar (2) channels in the presented version allows to additionally increase the flow rate inside the module, which ensures the creation of the necessary conditions for efficient mixing of components in the active zones and to achieve a high level of mixture homogeneity in a short period of time and without additional heating.

The presence of zones (4) of active mixing in conjunction with the location of the module (9) for “cold” mixing inside the tank, allows to increase the dispersion, the efficiency of the processes of mixing and homogenization of components at temperatures of 20-30 °, which will also reduce energy consumption.

Thus, the proposed utility model allows to increase the homogeneity of the homogenization of the components during mixing, dispersion and reduce energy consumption when mixing base oils and various additive packages.

A utility model has been disclosed above with reference to a specific embodiment. For specialists, other embodiments of the utility model that do not change its essence, as disclosed in the present description, may be obvious. Accordingly, a utility model should be considered limited in scope only by the following utility model formula.
