Description
Technical Field
The invention relates to the technical field of new energy automobiles, in particular to an energy storage device for a high-viscosity medium and a using method thereof.
Background
Along with the popularization of new energy automobiles, the yield and the sales volume of electric automobiles in the new energy automobiles are rapidly improved, a battery is one of three key components of the electric automobiles, and the temperature control of the battery is an important guarantee for ensuring the safe operation of the battery; in the prior art, the battery core, the module and the battery assembly of the battery are coated with heat conducting glue, and the temperature control of the battery is realized by combining a water cooling mode. Therefore, the coating of the heat-conducting glue is an important process for the production of the electric automobile.
The existing glue spreading system for the heat-conducting glue is generally composed of a glue supply pump, a high-pressure rubber tube, a pressure reducing valve, quantitative equipment (such as a booster pump, a quantitative cylinder and the like), a glue gun and a mixing tube, when the glue spreading system is used, high-viscosity media (such as heat-conducting glue or components of the heat-conducting glue) are continuously pumped out at high pressure through the glue supply pump, and pressure is reduced through the pressure reducing valve, so that the high-viscosity media output by the pressure reducing valve are stabilized within a pressure range allowed by the quantitative equipment during working, then the quantitative equipment sends the received media to the glue gun, and the glue gun stirs and extrudes the received high-viscosity media or media to realize extrusion coating. It can be seen that the heat-conducting adhesive of the high-viscosity medium needs to pass through four devices before extrusion coating, so that the conveying path of the heat-conducting adhesive is longer, but the heat-conducting adhesive not only has high viscosity property, but also contains a large amount of particles with strong abrasiveness, so that on one hand, the pressure loss in the whole conveying process is larger, the output pressure of the pressure supply pump needs to be larger, and the requirement on the equipment of the pressure supply pump is increased; on the other hand, abrasive particles contained in the high-viscosity medium affect each device, and particularly for a pressure reducing valve needing pressure reduction, the pressure reducing valve not only needs to bear unstable medium pressure from a glue supply pump (trough pressure occurs when the glue supply pump supplies glue, and the trough pressure is much lower than common output pressure), but also needs to bear abrasion of the medium to the pressure reducing valve, so that the pressure reducing valve is frequently failed, the replacement cost is high, and the production efficiency is affected in the replacement process; in addition, in practical application, the extrusion coating process is intermittent, one area/product is extruded, extrusion coating is suspended, and then another area/product is extruded, and because the interval time between extrusion coating and extrusion coating is short, and the conveying path of the high-viscosity medium is long and the pressure loss is large, in order to ensure the normal starting of the next extrusion coating, the spray gun and the quantitative equipment are only suspended when extrusion coating is suspended; however, other problems are also brought about, for example, when the dosing device is suspended, the pressure reducing valve and the glue supply pump are always opened, before the dosing device is opened, the pressure bearing pressure of the pressure reducing valve is far higher than the normal working pressure, and the output end of the pressure reducing valve is quickly decompressed when the pressure reducing valve is in operation, the output pressure of the pressure reducing valve at the moment can be momentarily close to the maximum inlet working pressure of the dosing device, and after the dosing device is operated for a period of time, the glue supply pump has a trough pressure due to a long medium conveying path, so that the output pressure of the pressure reducing valve is basically at the minimum working pressure of the dosing device, and in actual use, the dosing device cannot necessarily completely meet the normal working requirement of the dosing device when the dosing device is at the minimum working pressure, and the extrusion coating quality of a subsequent spray gun is poor. The gluing system of the heat-conducting glue has high overall cost, poor reliability of long-period operation and easy influence on production efficiency, and becomes the bottleneck of battery production.
For research and development solution above-mentioned problem, the inventor needs the demand of steady voltage from dosing device to start, borrows the steady voltage structure among the prior art for reference, if supply the accumulator of gluing the pump and need stablizing the sprue between the equipment of inlet pressure and go up the effect of installation, the accumulator mainly plays the effect of stablizing sprue outlet pressure to guarantee that sprue exit linkage's the equipment that needs stablize inlet pressure guarantees to have stable inlet pressure. The types of the prior energy accumulators are basically divided into three types, namely a leather bag type energy accumulator, a diaphragm type energy accumulator and a piston type energy accumulator, and the leather bag type energy accumulator and the diaphragm type energy accumulator have the advantages of sensitive response and simple structure, but cannot be used for high-viscosity media due to material limitation and working condition limitation. The piston type energy accumulator has the advantages of long service life and can be used for common high-viscosity media, the piston type energy accumulator comprises a piston cylinder, a piston slides in the piston cylinder, a connecting channel is arranged on the piston cylinder and is communicated with the main flow channel, and when the outlet pressure of the main flow channel is too high, the piston is far away from the main flow channel, so that the flowing medium in the main flow channel enters the communicating channel or enters the piston cylinder along the connecting channel to reduce the outlet pressure of the main flow channel; and when the outlet pressure of the main flow passage is too low, the piston is close to the main flow passage so as to extrude the connecting passage or the connecting passage and the medium left in the piston cylinder into the main flow passage through the connecting passage to increase the outlet pressure of the main flow passage.
However, when the existing piston type energy accumulator is used for stabilizing the pressure of a high-viscosity medium, the medium which firstly enters the communicating channel or the piston cylinder needs to be finally discharged, so that old glue is inevitably left in the connecting channel or the piston cylinder, long-term retention of the old glue is easy to cause a caking phenomenon, and in order to avoid the problem, the caking phenomenon is reduced by the scheme that the connecting channel and/or the piston cylinder are wrapped by a heating structure to increase the fluidity of the medium in the field; however, for the case of higher medium viscosity, such as the case of heat-conducting glue, the viscosity of the heat-conducting glue is relatively higher, and the caking phenomenon still exists under the non-flowing condition for a long time due to the material components, and if the piston-type energy accumulator is used in the gluing system on the heat-conducting glue, once the caking occurs, the massive material enters the quantitative equipment or the spray gun to cause the blockage of the quantitative equipment or the glue gun, so that the extrusion coating work must be completely suspended to find the cause and the blocked pipeline position, the extrusion coating work is seriously affected, the cost caused by the blockage is far higher than the cost of using the pressure reducing valve, and in the actual application, the existing energy accumulator scheme cannot be applied to the high-viscosity gluing system.
Disclosure of Invention
The invention aims to provide an energy storage device for a high-viscosity medium, and aims to solve the problems that a pressure reducing valve of a gluing system in the prior art is easy to damage, the replacement cost is high, and the existing energy storage device cannot be applied to the pressure stabilization working condition of a high-viscosity heat-conducting glue supply system.
In order to achieve the purpose, the invention adopts the following technical scheme:
the energy storage device for the high-viscosity medium comprises a pressure regulator and a cylinder body, wherein a piston is connected to the cylinder body in a sliding mode, the pressure regulator is used for applying external force to the piston, a communicating channel is arranged between the cylinder body and a main flow channel, a cavity between the piston and the communicating channel in the cylinder body is called a first chamber, the communicating channel comprises an inlet channel and an outlet channel which are both communicated with the main flow channel, the first chamber is always communicated with the inlet channel and the outlet channel at the same time, one of the inlet channel and the outlet channel is connected to the side wall of the first chamber, and the other of the inlet channel and the outlet channel is connected to the bottom of the first chamber; one-way valves are arranged on the inlet channel and the outlet channel, so that the medium can only flow into the first chamber from the inlet channel and can only be discharged out of the first chamber from the outlet channel.
The principle and the advantages of the scheme are as follows: when the energy storage device is used, the stroke of the bottom of the piston is between the inlet channel and the outlet channel 4, the energy storage device is mainly divided into four working states of a filling state, a filling stop state, a discharging state and a discharging stop state when working, when the filling state is carried out, namely the outlet pressure of the main channel is overhigh, because the main channel, the inlet channel, the first chamber and the outlet channel are communicated all the time, the upstream pressure borne by the one-way valve in the inlet channel is higher than the downstream pressure to open, the one-way valve on the outlet channel is closed because the upstream pressure is lower than the downstream pressure, and the high-viscosity medium can enter the first chamber from the main channel through the inlet channel and the one-way valve to fill the medium in the cylinder body, for example, if the inlet channel is arranged on the side wall of the first chamber, with the continuous entering of the medium, the medium which firstly enters the first chamber is firstly pushed to the outlet channel far away from the inlet channel; if the inlet channel is arranged at the bottom of the first chamber, medium with over-high pressure on the main channel enters the first chamber through the inlet channel and the one-way valve, the medium entering the first chamber pushes the piston to move towards the direction of the outlet channel continuously, and the medium entering the first chamber first is close to the outlet channel first; and (3) as the filling enters the final stage, the speed of the piston pushed by the medium is slower and slower until the piston completely stops moving, at the moment, the downstream pressure of the one-way valve in the inlet channel is gradually increased to be close to the pressure of the main channel, the one-way valve on the inlet channel is closed, the filling process is completed, and at the moment, the energy storage device is in a filling completion state.
When the outlet pressure of the main channel is lower, the upstream pressure borne by the one-way valve on the inlet channel is lower than the downstream pressure to close, the upstream pressure borne by the one-way valve on the outlet channel is higher than the downstream pressure to open, the medium is extruded and discharged from the cylinder by the piston, and at the moment, the medium is in a discharging state, and because the medium entering the cylinder firstly approaches the outlet channel during medium filling, the medium closest to the outlet channel (namely the medium preferentially entering the cylinder) is preferentially discharged in the discharging state; when the discharging enters the final state, the moving speed of the piston is also reduced, the upstream pressure of the one-way valve in the outlet channel is gradually close to the pressure of the downstream main channel, and the one-way valve on the outlet channel is gradually closed to finish the discharging process, namely the discharging stop state.
The energy storage device enables media which enter preferentially to be discharged preferentially, the outlet pressure of a glue supply pump connected with the energy storage device is a process of continuously alternating ordinary pressure and wave trough pressure, during ordinary pressure, the pressure of the main runner is over-high, and during wave trough pressure, the pressure of the main runner is over-low, and the outlet pressure of the main runner is kept stable all the time under the action of the energy storage device; meanwhile, the outlet pressure of the main flow channel is alternatively high and low, namely four states of the energy storage device are continuously circulated, so that the high-viscosity medium entering the energy storage device can be discharged quickly in a first-in first-out mode, the high-viscosity medium left in the energy storage device is avoided, the energy storage device is prevented from caking, and the problem that the existing energy storage device cannot be applied to the pressure stabilization of the high-viscosity medium similar to heat-conducting glue is solved.
In addition, the energy storage device can replace a pressure reducing valve to be used in a gluing system of a high-viscosity medium similar to heat-conducting glue, so that the output pressure of the glue supply pump is greatly reduced, the requirement on the glue supply pump is reduced, the purchase cost and the maintenance cost of the glue supply pump are favorably reduced, the service life of the glue supply pump is prolonged, and meanwhile, the long-term reliable operation of the gluing system is favorably promoted; and this scheme need not use the relief pressure valve, and then has avoided the problem of the unplanned shutdown that brings when the replacement cost height that brings because of using the relief pressure valve and changing completely, is favorable to improving production efficiency and improves the reliability of rubber coating system long period operation.
In addition, due to the use of the energy storage device, when the extrusion coating is stopped for a short time, the high-pressure high-viscosity medium conveyed by the glue pump enters the first cavity of the energy storage device for energy storage, and when the inlet pressure of the quantitative equipment is insufficient in a period of extrusion coating, pressure compensation can be timely provided for the inlet pressure of the quantitative equipment, so that the problem of poor extrusion coating effect caused by the change of the inlet pressure of the quantitative equipment is avoided.
In addition, when the steady voltage scope of the exit pressure of sprue is adjusted through energy storage device to needs, can adjust energy storage device's steady voltage scope through the external force that the adjustment voltage regulator applyed on the piston, and then realize the purpose of sprue exit pressure adjustment, improve the practicality of this scheme, for example, if want to let energy storage device still play the effect of buffer memory jar on the basis of existing steady voltage effect then let the energy storage device intussuseption fill the medium more, reduce the effort of voltage regulator to the piston this moment, so that the piston is promoted by the medium more easily, in order to realize the more circumstances of medium in the energy storage device.

In the first embodiment, as shown in fig. 1 to 6, the energy storage device for high viscosity media comprises a pressure regulator 8 and a cylinder body 1, wherein the cylinder body 1 is connected with a piston 2 in a sliding manner, an end cover 7 is fixed on the cylinder body 1, the pressure regulator 8 is installed on the end cover 7, and the pressure regulator 8 is used for applying external force to the piston 2; a communication channel is arranged between the cylinder 1 and the main channel 100, and a cavity between the piston 2 in the cylinder 1 and the communication channel is called as a first chamber 11; the pressure regulator 8 may be an elastic member (e.g., a spring) installed between the output end of the linear module and the piston 2, and the elastic member applies the pressure applied by the linear module to the piston 2; the pressure regulator 8 can also be a cylinder, and the output end of the cylinder is connected with the piston 2; in the drawing of the embodiment, a second closed chamber 14 is formed between the end cover 7 and the piston 2, and when the second chamber 14 and the first chamber 11 are located on both sides of the piston 2, the pressure regulator 8 adopts an inflation unit, and the inflation unit adjusts the magnitude of the external force applied to the piston 2 through the change of the amount of inflation gas. In addition, when the pressure regulator 8 uses the inflation unit, the second chamber 14 is further connected with a pressure testing unit, the pressure testing unit uses a pressure gauge 9, and the pressure gauge 9 is used for testing the pressure of the second chamber 14.
The communicating channel comprises an inlet channel 3 and an outlet channel 4 which are communicated with the main channel 100, a chamber I11 is communicated with the inlet channel 3 and the outlet channel 4 all the time, specifically, a communicating gap 5 is formed between the side wall of the piston 2 and the cylinder 1, the communicating gap 5 can be communicated with the chamber I11 to communicate the inlet channel 3 and the outlet channel 4 all the time, one of the inlet channel 3 and the outlet channel 4 is connected to the side wall of the chamber I11, and the other is connected to the bottom of the chamber I11, and the inlet channel 3 and the outlet channel 4 are both provided with one-way valves 6, so that a medium can only flow into the chamber I11 from the inlet channel 3 and can be discharged out of the chamber I11 from the outlet channel 4. The junction of the inlet channel 3 with the primary channel 100 is located upstream of the junction of the outlet channel 4 with the primary channel 100.
The specific use method of the energy storage device of the embodiment is as follows:
taking fig. 1 as an example, a cylinder 1 is located at the upper end of a main flow passage 100, when the energy storage device is used, the stroke of the bottom of a piston 2 is between an inlet passage 3 and an outlet passage 4, the energy storage device is mainly divided into four working states of a filling state, a filling stop state, a discharging state and a discharging stop state when working, when the filling state is over-high, namely the outlet pressure of the main passage, a communication gap 5 exists between the cylinder 1 and the piston 2, the communication gap 5 and a chamber one 11 are used for always communicating the inlet passage 3, the chamber one 11 and the outlet passage 4, an upstream pressure applied to a check valve 6 in the inlet passage 3 is higher than a downstream pressure and is opened, a check valve 6 on the outlet passage 4 is closed because the upstream pressure is lower than the downstream pressure, high-viscosity media can enter the chamber one 11 from the main flow passage 100 through the inlet passage 3 and the check valve 6, the filling of the medium in the cylinder body 1 is realized, and along with the continuous entering of the medium, the medium which firstly enters the first chamber 11 is firstly pushed to the outlet channel 4 far away from the inlet channel 3; and (3) as the filling enters the final stage, the speed of the piston 2 pushed by the medium is slower and slower until the piston 2 completely stops moving, at the moment, the downstream pressure of the one-way valve 6 in the inlet channel 3 is gradually increased to be close to the pressure of the main channel, the one-way valve 6 on the inlet channel 3 is closed, the filling process is completed, and at the moment, the energy storage device is in a filling completion state.
When the outlet pressure of the main channel is lower, the upstream pressure borne by the check valve 6 on the inlet channel 3 is lower than the downstream pressure to be closed, the upstream pressure borne by the check valve 6 on the outlet channel 4 is higher than the downstream pressure to be opened, the medium is extruded and discharged from the cylinder 1 by the piston 2, and at the moment, the medium is in a discharging state, and because the medium which firstly enters the cylinder 1 during medium filling is firstly close to the outlet channel 4, the medium which is closest to the outlet channel 4 (namely the medium which preferentially enters the cylinder 1) is preferentially discharged in the discharging state; when the discharging enters the final state, the moving speed of the piston 2 is also reduced, the upstream pressure of the one-way valve 6 in the outlet channel 4 is gradually close to the pressure of the main channel 100 at the downstream, and the one-way valve 6 on the outlet channel 4 is gradually closed to finish the discharging process, namely the discharging stop state.
In the four states described above, the stroke of the piston 2 is always between the inlet channel 3 and the outlet channel 4, so as to ensure that the medium in the states described above always meets the first-in first-out principle.
Fig. 3 differs from fig. 1 in that the outlet channel 4 is also communicated with the bottom of the chamber 11, except that the position where the outlet channel 4 is communicated in fig. 1 is the bottom of the cylinder 1, and the position where the outlet channel 4 is communicated in fig. 3 is the bottom of the side wall of the cylinder 1, and the position of the outlet channel 4 is basically consistent in fig. 1 and 3, so the whole process of the energy storage device is basically the same
Fig. 4 differs from fig. 1 in the case where the cylinder 1 and the piston 2 are arranged below the main flow channel 100, in which case the medium introduced into the cylinder 1 is also preferentially adjacent to the outlet channel 4, so that a first-in first-out during operation of the energy storage device is also ensured.
The solution of fig. 5, in which the cylinder body 1 and the piston 2 are oriented such that the inlet channel 3 communicates with the bottom of the chamber one 11 and the outlet channel 4 communicates with the side wall of the piston 2, also ensures the first-in first-out during operation of the energy storage device.
In the scheme, the energy storage devices all follow the principle of first-in first-out of media, the outlet pressure of a glue supply pump connected with the energy storage devices is the process of continuously alternating common pressure and wave trough pressure, the common pressure means that the pressure of the main flow channel 100 is too high, and the wave trough pressure means that the pressure of the main flow channel 100 is too low, and the outlet pressure of the main flow channel 100 is always kept stable through the action of the energy storage device; meanwhile, because the outlet pressure of the main runner 100 is alternatively high and low, namely four states of the energy storage device are continuously circulated, the high-viscosity medium entering the energy storage device can be discharged quickly in a first-in first-out mode, the high-viscosity medium left in the energy storage device is avoided, the energy storage device is prevented from caking, and the problem that the conventional energy storage device cannot be applied to the pressure stabilization of the high-viscosity medium similar to heat-conducting glue is solved.
In addition, the energy storage device can replace a pressure reducing valve to be used in a gluing system of a high-viscosity medium similar to heat-conducting glue, so that the output pressure of the glue supply pump is greatly reduced, the requirement on the glue supply pump is reduced, the purchase cost and the maintenance cost of the glue supply pump are favorably reduced, the service life of the glue supply pump is prolonged, and meanwhile, the long-term reliable operation of the gluing system is favorably promoted; and this scheme need not use the relief pressure valve, and then has avoided the problem of the unplanned shutdown that brings when the replacement cost height that brings because of using the relief pressure valve and changing completely, is favorable to improving production efficiency and improves the reliability of rubber coating system long period operation.
In addition, due to the use of the energy storage device, when the extrusion coating is stopped for a short time, the high-pressure high-viscosity medium conveyed by the glue pump enters the first cavity 11 of the energy storage device for energy storage, and when the inlet pressure of the quantitative equipment is insufficient in a period of extrusion coating, pressure compensation can be timely provided for the inlet pressure of the quantitative equipment, so that the problem of poor extrusion coating effect caused by the change of the inlet pressure of the quantitative equipment is avoided.
Besides, when the steady voltage scope of the outlet pressure of the main runner 100 needs to be adjusted through the energy storage device, the steady voltage scope of the energy storage device can be adjusted by adjusting the external force exerted by the pressure regulator 8 on the piston 2, and then the purpose of adjusting the outlet pressure of the main runner 100 is realized, the practicability of the scheme is improved, for example, if the energy storage device is supposed to play the role of the buffer tank on the basis of the existing steady voltage role, the filling medium in the energy storage device is more, at the moment, the acting force of the pressure regulator 8 on the piston 2 is reduced, so that the piston 2 is more easily pushed by the medium, and the condition that the medium in the energy storage device is more is realized.
