Detailed description of the preferred embodiments

The following detailed description is made with reference to the accompanying drawings.

Example 1

The application provides a lubricating oil conveyor, it includes branch pipe 1, hybrid tube 2, buffer gear 3, material jar 4 and blending tank 5.

According to a specific embodiment shown in fig. 1, a plurality of interfaces capable of being butted with the branch pipes 1 are arranged at different sections of the mixing pipe 2, so that different branch pipes 1 for conveying different fluid substances can be butted on the interfaces of the mixing pipe 2 according to use requirements, and thus the different fluid substances are mixed during the directional flow in the mixing pipe 2, and mixed lubricating oil with specific component ratio and performance is produced. One end of each branch pipe 1 far away from the mixing pipe 2 is connected with each material tank 4, so that the materials are conveyed. At least one inlet end of the mixing pipe 2 is further provided with a buffer mechanism 3 capable of buffering the inflowing fluid substance. The buffer mechanism 3 carries out adaptive buffer adjustment on flow fluctuation in the process of conveying the fluid substances, so that when the pressure in the pipeline is large, the actual passing flow is reduced in a mode of increasing passing resistance, and the actual flow in the mixing pipe 2 can be always kept in a basically stable state under the condition that the input flow of the branch pipe 1 fluctuates. Preferably, the mixing pipe 2 defines a corrugated pipe structure having a plurality of branch ports and a plurality of convergence ports alternately arranged, so that the fluid substance flowing directionally inside the pipe can be subjected to the change of the pipe structure in different sections of the pipe to generate the change of the flow state, and the multiple components in the fluid substance can be accelerated to diffuse under a continuously changed flow state, so that the multiple components are forced to be effectively mixed with each other, and the mixing efficiency of the mixed lubricating oil is improved. Preferably, a mixing tank 5 is also detachably connected to the output end of the mixing tube 2. The different mixing tanks 5 store lubricating oil of different characteristics having been subjected to the blending treatment. The production line is simplified and independent processing steps contained in the production flow are reduced by integrating component blending and material conveying of the mixed lubricating oil. In addition, the lubricating oil conveying device is used for mixing components in the conveying process, so that the device can perform large-batch blending treatment, and the continuous production of the product oil can be realized.

Preferably, the branch pipes 1 comprise at least a first branch pipe 11 for conveying a first fluid substance as base oil into the main pipe 21 of the mixing pipe 2 and a second branch pipe 12 for conveying a second fluid substance as additive into the parallel branch pipes 22 of the mixing pipe 2. Preferably, the mixing pipe 2 is provided with a plurality of alternately connected main pipes 21 and parallel branch pipes 22 in such a manner that the fluid substances form a flow by periodically dividing and combining. Specifically, the periodic separation and combination means that the liquid flow formed by the directional flow of the fluid substances in the pipeline can be divided and converged in different sections of the pipeline along with the specific pipeline shape of the splicing structure of the main pipe 21 and the parallel branch pipes 22, so as to change the flow state of the liquid flow. The flow state of the fluid stream may refer to the flow rate, pressure experienced within the conduit, and distribution of the constituent components of the fluid material forming the fluid stream. Preferably, two parallel branch pipes 22 arranged in parallel are used to receive the part of the fluid mass flowing out of the upstream main pipe 21, and two parallel branch pipes 22 belonging to the same group are used to introduce the same additive at the same time. As shown in fig. 2, the parallel branched pipes 22 connected in series in a plurality of stages are respectively connected to second branch pipes 12 capable of introducing different additives so that the base oil can be added with a plurality of additives after sequentially passing through the parallel branched pipes 22 in a plurality of stages. Further preferably, the two parallel branch pipes 22 of the same group can also be used as mixing processing spaces for introducing different additives, and the specific mixing process can be adjusted according to production requirements, so that different additives can reach a uniformly distributed state under the condition of being mixed into base oil, and thus the mixed lubricating oil after being mutually blended can have specific performance.

Preferably, the branch pipes 1 communicating with different sections of the mixing pipe 2 are used for the directional transport of the specific substance in such a way that there is a difference in the introduction parameters. Further preferably, the introduction parameter may refer to an introduction time, an introduction amount, a communicated port position, and an upstream-downstream relationship of the port in the flow direction. Preferably, the first fluid substance which is branched off from the main pipe 21 and enters the parallel branch pipes 22 can be mixed with the second fluid substance which directly enters the parallel branch pipes 22 from the second branch pipe 12, so that the mixing of the multiple fluid substances which sequentially join the mixing pipe 2 is orderly completed in the process of directional conveying.

Preferably, the first branch pipe 11 of the branch pipe 1 is communicated with the main pipe 21 of the mixing pipe 2 at the most upstream of the flow passage, so that the first branch pipe 11 can input the base oil as the main component of the lubricating oil into the mixing pipe 2. Preferably, the second branch pipe 12 of branch pipe 1 is adjustably connected to the parallel branch pipes 22 at different sections of the mixing pipe 2 so that the additive it delivers can be controllably introduced into the base oil flowing through the parallel branch pipes 22. The arrangement of the branch pipes 1 enables different components for producing mixed lubricating oil to be mixed in the conveying process, the branch pipes 1 are arranged to be of a detachable structure, fluid material storage containers located in different production areas can be conveyed at fixed points, and the defect that potential safety hazards are caused due to the fact that large containers are moved according to requirements is overcome. The branch pipe 1 can be butted with interfaces on different sections of the mixing pipe 2 according to requirements, so that the component mixing of the mixing pipe 2 can meet the requirements of multiple mixing processes, and various additives can be adjusted to lead-in parameters according to unique mixing parameter requirements, so that fluid substances existing in different sections of the same mixing pipe 2 can have different parameters. For example, the mixing temperatures required by different additives are different, so that in the actual mixing process, the heating layer on the surface of the mixing pipe 2 can be subjected to temperature adjustment in sections, so that the pipe internal temperatures of different sections of pipes are different, and the fluid substances which change synchronously with the pipe internal temperatures can be subjected to mixing treatment of the additives matched with the corresponding temperature thresholds in different sections.

As shown in fig. 1 and 2, the mixing pipe 2 may include a main pipe 21 and a parallel branch pipe 22. The multiple sections of main pipes 21 and the parallel branch pipes 22 are alternately arranged, so that a pipeline structure with a corrugated shape having a plurality of alternately arranged branch ports and convergence ports is built. The arrangement of the pipeline structure is such that the flow velocity and the pressure of the fluid in different sections of the mixing pipe 2 are different, the fluid is forced to continuously change the fluid state while the mixing pipe 2 is in a directional flow, and therefore, the mixing of a plurality of fluid substances conveyed into the mixing pipe 2 by different branch pipes 1 is completed in the corrugated pipeline structure. When the fluid material flows directionally along the conveying channel formed by the main pipe 21 and the parallel branch pipes 22 which are alternately arranged, the pressure applied to the fluid material is changed along with the change of the pipe diameter, so that the flow rate of the liquid flow is changed, the flow splitting island structure formed in the conveying channel for splitting and converging is used for enhancing the change of the fluid state, and the mixing treatment of the base oil after the additive is injected into the parallel branch pipes 22 is accelerated.

Specifically, the downstream end of the main pipe 21 connected to the first branch pipe 11 is connected to two parallel branch pipes 22 capable of dividing the fluid material to be transported into two. The two parallel branch pipes 22 having arc-shaped pipe bodies are communicated with the outlet section of the main pipe 21 in such a manner as to constitute a diversion island, so that the fluid substance flowing out of the main pipe 21 connected to the first branch pipe 11 flows into the two parallel branch pipes 22 connected in parallel, respectively, in such a manner as to be substantially equally divided by the diversion island. Preferably, the two arc angles of the arc-shaped flow-dividing islands defining the inflow end and the outflow end of the same group of parallel branch pipes 22 are adjusted in a gradient manner according to the upstream-downstream relationship in the flow channel of the mixing pipe 2, so that the fluid substance flowing through the convergence port is swirled.

Specifically, the pipe diameter of the parallel branch pipe 22 is smaller than that of the main pipe 21, so that the divided fluid substance can still flow directionally in the parallel branch pipe 22 in a full pipe state. Preferably, the front end of the diversion island constructed by the two parallel branch pipes 22 with arc-shaped pipe bodies is streamline curved in a specific plane, so that the diversion of the fluid substance can be completed in a mode without obvious resistance. Further preferably, the specific plane refers to a plane defined by the axes of the two parallel branch pipes 22 in parallel being coplanar with each other. Preferably, the flow dividing island can also realize the division of the fluid, so that the state of the fluid is changed, and particularly, after the divided fluid substance enters the parallel branch pipe 22 with a smaller pipe diameter, the fluid pressure is increased, the flow speed is forced to follow and rise, so that the activity of the components of the fluid substance is improved, and the additive introduced into the parallel branch pipe 22 can be more effectively mixed with the base oil.

Preferably, the ends of the two parallel branch pipes 22 are also provided with arc-shaped pipe bodies inclined against each other, so that the ends of the two parallel branch pipes 22 are jointed together again and communicated with the inlet end of the other main pipe 21, and thus the fluid substances flowing out of the two parallel branch pipes 22 are subjected to secondary convergence in the main pipe 21 located at the downstream of the two parallel branch pipes.

Preferably, the arc-shaped pipe bodies arranged at the ends of the parallel branch pipes 22 can define that the ends of the branch islands are streamline curved surfaces in the same specific plane. Further preferably, the specific plane refers to a plane defined by the axes of the two parallel branch pipes 22 in parallel being coplanar with each other. Preferably, the front end and the tail end of the shunting island are arranged in a way that the curved surface curvature difference exists. Specifically, the curvature radius of the streamline curved surface used for shunting at the front end of the shunting island is larger than the curvature radius of the streamline curved surface used for converging at the tail end of the shunting island, so that when the fluid substances in the two parallel branch pipes 22 connected in parallel are converged at the tail end of the shunting island, an eddy current capable of preventing the fluid substances from being stuck on the pipe wall is formed in the butt joint area of the pipeline according to the reduction of the curvature of the curved surface at the tail end of the shunting island. Further preferably, the vortex flow can accelerate the self-rotation of the liquid flow formed by the fluid substances, so that the activity of the component molecules in the fluid substances is further improved, and the mixing between different fluid substances is accelerated.

Preferably, the parallel branch pipe 22 includes two arc-shaped pipe lines constituting a streamline curved surface and a straight line pipe line for communicating with the second branch pipe 12. Specifically, the annular pipe cavity of the second branch pipe 12 is sleeved on the outer wall of the linear pipeline of the parallel branch pipe 22. The inner diameter surface of the annular tube cavity can be attached to the outer wall of the straight line pipeline of the parallel branch pipe 22. As shown in fig. 3, a plurality of openings 121 are circumferentially spaced on the inner side wall of the annular cavity, so that the additive in the second branch pipe 12 can be discharged after passing through the openings 121. Preferably, a plurality of through holes 221 communicated with the annular tube cavity of the second branch tube 12 are arranged on the tube wall of the parallel branch tube 22 abutted with the second branch tube 12 at intervals in the circumferential direction. It is further preferable that the positions of the opening 121 and the through-hole 221 correspond to each other, so that the additive in the second branch pipe 12 enters the parallel branch pipes 22 after passing through the opening 121 and the through-hole 221 in sequence. Specifically, the openings 121 and the through holes 221 are circumferentially spaced on two concentric circles, so that the additive conveyed by the openings can be mixed into the base oil in a multi-point uniform introduction manner, and the mixing difficulty of the additive and the base oil is reduced.

As shown in fig. 3 and 5, a one-way communication member 24 is provided in an additive introduction port defined by any of the openings 121 and the through-holes 221. The one-way communication element 24 is able to control the additive delivered by the second branch 12 to be injected at a set pressure into the base oil delivered by the parallel branch 22. Preferably, the one-way conduction member 24 may be composed of a pressure valve 241, a check valve 242, and a nozzle 243 connected in sequence. The pressure valve 241 is used to limit the introduction pressure of the additive, so that when the pressure of the second fluid substance at the side where the pressure valve 241 is communicated with the second branch pipe 12 reaches a designated value, the valve of the pressure valve 241 is opened, and the second fluid substance passes through the pressure valve 241 and further passes through the check valve 242 and the nozzle 243, so that the second fluid substance enters the parallel branch pipes 22 in a state with a certain initial power, thereby accelerating the movement and dispersion of the additive inside the base oil. Preferably, the non-return valve 242 is able to limit the unidirectional delivery of the additive. The nozzle 243 is provided to disperse the pressurized second fluid substance so that the second fluid substance can be directionally injected into the parallel branch pipes 22 in a relatively dispersed manner. Further preferably, the nozzle 243 may be provided in a triangular pyramid structure or a hemispherical structure. When the nozzle 243 is a hemispherical structure, the hemispherical arc surface is provided with a plurality of micro openings capable of directly discharging the pressurized liquid therein, so that the liquid in the nozzle can be sprayed into the parallel branch pipes 22 through the openings under a certain pressure.

Preferably, a shunt column 23 coinciding with the axis of the section of the straight pipeline is arranged inside the section of the straight pipeline in which the parallel branch pipe 22 is sleeved with the second branch pipe 12. The splitter column 23 is able to change the flow path configuration of the section such that the fluid substance can only flow directionally in the solid cylindrical space with annular cross section between the shunt tubes 22 and the splitter column 23. Preferably, the end of the splitter column 23 close to the upstream of the flow channel defined by the pipe is provided with a conical shape, so that it only changes the flow path, the size of the flow space, the flow pressure and the like of the fluid substance, without obstructing the flow of the fluid substance and avoiding the reduction of the kinetic energy carried by the fluid substance. The activity of the internal components of the fluid substance is ensured. Preferably, the additive sprayed from the nozzle 243 can also impact on the surface of the flow dividing column 23, further promoting the diffusion of the additive components, so that the additive is more quickly diffused to the area inside the tube cavity of the parallel branch tube 22 not directly covered by the nozzle 243. Preferably, the tapping column 23 is positioned and installed by a plurality of support columns with a section similar to that of the fin, so that it can be suspended in the parallel branch pipes 22.

As shown in fig. 1, 2 and 4, a turbine 25 capable of further agitating the fluid substance is also provided in the straight line of the parallel branch pipes 22. Preferably, the turbine 25 is located downstream of the splitter column 23, so that the fluid substance that completes the mixing of the additive in the section of the pipeline defined by the splitter column 23 can be accelerated to mix under the agitation of the turbine 25, so that the constituent molecules of the fluid substance have a more active state of motion, promoting a uniform distribution of the different constituent molecules within the fluid substance. Preferably, the turbine 25 is driven by the flow forces carried by the directional flow of the fluid substance occurring in the parallel branch 22. The turbine 25, driven in rotation by the power of the directional flow of the fluid substance, is able to perform the cutting of the fluid substance, thus stirring the distribution of the components inside the fluid substance and thus accelerating the mixing of the components of the fluid substance. Preferably, the turbine 25 can be directly installed at the tail of the splitter column 23 or can be separately installed by using a support column. The support column that is located pipeline inside that this application relates to all adopts the column piece that the cross-section is similar with the fin cross-section to process, reduces the hindrance of support column fluid flow.

Preferably, a damper mechanism 3 capable of adjusting the flow rate of the fluid material supplied to the mixing pipe 2 is further provided between the first branch pipe 11 and the main pipe 21. The damper mechanism 3 can reduce the pressure of the fluid substance on the mixing pipe 2 at the time of a change in the flow rate by generating a damper flow rate to reduce the fluid pressure when the flow rate in the main pipe 21 changes. The buffer mechanism 3 eliminates the defect that the first fluid substance flowing into the mixing tube has uneven flow due to an empty tube or turbulent flow to a certain extent, so that the fluid substance flowing into the mixing tube can always keep a relatively stable flow.

As shown in fig. 1, 6 and 7, the buffer mechanism 3 at least includes a valve body 31, a central square tube 32, a flow guide plate 33, a transmission shaft 34, a return plate 35 and a flow blocking plate 36. Both ends of the valve body 31 are connected to the outflow end of the first branch pipe 11 and the inflow end of the main pipe 21 by a sleeve joint, thereby adjusting the state of the fluid material flowing from the first branch pipe 11 into the main pipe 21. Preferably, the communicating passage inside the valve body 31 is changed by providing the center square tube 32 so that the fluid substance adjustably flows into the main tube 21 from the gap space between the valve body 31 and the center square tube 32 and the inner square-hole lumen of the center square tube 32. Preferably, a reflux plate 35 and a baffle plate 36 are disposed in parallel in the square lumen of the central square tube 32. The backflow plate 35 and the flow blocking plate 36 are connected with the central square pipe 32 through a shaft rod penetrating through the central axis of the backflow plate 35 and the flow blocking plate 36, the backflow plate 35 and the flow blocking plate 36 which are arranged in the central square pipe 32 can rotate around the shaft rod, the flow size of fluid substances allowed to pass through the central square pipe 32 is limited according to the included angle between the backflow plate 35 and the cross section of the central square pipe 32, and therefore the flow is adjusted. Preferably, the flow baffle 36 is located downstream of the return plate 35, and the flow baffle 36 is connected to the return plate 35 by a hinge rod 37, so that the flow baffle 36 can follow the return plate 35 for rotation.

Preferably, the shaft of the return plate 35 is connected to the transmission shaft 34 in a manner of penetrating through the tube body of the center square tube 32, so that the return plate 35 can be interlocked with the flow guide plate 33 connected to the transmission shaft 34. Preferably, the flow guide plate 33 is supported in the gap space between the valve body 31 and the center square pipe 32 by the transmission shaft 34, and preferably, the flow guide plate 33 may be designed in a fan shape according to the sectional shape of the gap space between the valve body 31 and the center square pipe 32. Further preferably, the transmission shaft 34 is disposed in a manner of coinciding with a diameter direction of a certain cross section of the tubular valve body 31, and the flow guide plate 33 is disposed in a manner of forming a certain included angle between a plate surface of the flow guide plate and a flow direction of the fluid material in the gap space, so that the flow guide plate 33 deflects in different sizes according to a flow rate of the fluid material, thereby driving the flow return plate 35 and the flow baffle plate 36 to rotate, and forcing the flow return plate 35 and the flow baffle plate 36 to adjust an actual flow guide amount inside the central square tube 32. Preferably, two flow guide plates 33 are symmetrically arranged according to requirements, and the two flow guide plates 33 are arranged at two ends of the shaft rod of the return plate 35 through two coaxial transmission shafts 34.

Preferably, the plate body plane of the flow-guide plate 33 and the plate body plane of the flow-return plate 35 are perpendicular to each other, so that in the case where the flow-guide plate 33 is subjected to a small impact force and forms an angle of more than 45 ° with the axis of the central square tube 32, the flow-return plate 35 forms an angle of less than 45 ° with the axis of the central square tube 32, so that the central square tube 32 can allow more fluid substances to pass through to supplement the flow rate of the fluid flowing into the main tube 21. When the fluid impact force applied to the flow guide plate 33 is large and gradually deflects to an angle smaller than 45 degrees with the axis of the central square tube 32, the angle between the flow return plate 35 and the axis of the central square tube 32 is increased, so that the passing amount of fluid substances in the central square tube 32 is reduced, and the flow rate of the fluid flowing into the main tube 21 is further reduced. Preferably, a torsion spring is provided on the driving shaft 34 connected to the flow guide plate 33 to define an initial relative position of the flow guide plate 33. The linkage type buffer structure can effectively weaken the influence of the flow fluctuation of the fluid substance in the first branch pipe 11 on the flow of the fluid flowing into the main pipe 21, so that the flow of the fluid flowing into the main pipe 21 can always keep a relatively stable value.

Preferably, the end of the transmission shaft 34 far from the central square pipe 32 can also extend to the outside of the buffer mechanism 3 in a manner of penetrating through the valve body 31, so as to be connected with the flow valve in the second branch pipe 12 through the transmission mechanism, so that the flow rate of the additive in the second branch pipe 12 can be synchronously adjusted along with the real-time flow rate of the buffer mechanism 3 flowing into the main pipe 21, thereby maintaining the mixing ratio between the base oil and the additive, and ensuring the component proportion and quality of the actually produced mixed lubricating oil.
