Description

Technical Field

[0001] The present invention belongs to the technical field of filling pump equipment, and in particular relates to a hydraulic oil tank cooling device and a control method for a paste filling pump. Background Art

[0002] During the operation of a paste filling pump, the hydraulic oil in the tank generates heat due to various factors, such as mechanical friction during the operation of the hydraulic pump and the conversion of energy losses as the hydraulic oil flows through components such as the throttle valve into heat. Excessive oil temperature can have a number of adverse effects on the performance and service life of the filling pump's hydraulic components. For example, excessively high oil temperature can reduce the viscosity of the hydraulic oil, leading to increased leakage within the hydraulic system, reduced volumetric efficiency, and impacting the filling pump's output pressure and flow stability. Excessively high oil temperature can also accelerate the oxidation and deterioration of the hydraulic oil, generating sludge and sediment that can clog hydraulic components and pipelines, causing failures. Furthermore, excessively high oil temperature can accelerate the aging and deformation of seals, reducing sealing performance and exacerbating leakage.

[0003] Currently, some existing hydraulic oil tank cooling methods for filling pumps have certain limitations. Some have low cooling efficiency and cannot effectively control the oil temperature within a reasonable range. Other cooling systems are slow to respond and cannot adjust the cooling intensity in time according to changes in oil temperature. Furthermore, the pulsed operating characteristics of paste filling pumps prevent rapid heat dissipation during pumping intervals, resulting in large fluctuations in oil temperature.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] Reference Figures 1-6 The present invention provides a paste filling pump hydraulic oil tank cooling device, comprising:

[0033] The first heat exchange assembly includes a heat exchange oil tank 2, which is connected to the hydraulic oil tank 1. A first heat exchange water circuit is provided in the heat exchange oil tank 2. The first heat exchange water circuit is used to reduce the oil temperature in the heat exchange oil tank 2. The water inlet end of the first heat exchange water circuit is connected to a water supply component, and the water outlet end of the first heat exchange water circuit is connected to a heat dissipation water tank 7.

[0034] The second heat exchange assembly includes a liquid outlet pipe fitting, which runs through the interior of the hydraulic oil tank 1 and is used to reduce the oil temperature in the hydraulic oil tank 1. The water inlet end of the liquid outlet pipe fitting is connected to the water supply part, and the water outlet end of the liquid outlet pipe fitting is connected to the heat dissipation water tank 7;

[0035] The valve assembly is connected between the water outlet end of the first hot water exchange circuit and the water outlet end of the liquid outlet pipe. When the valve assembly is in a closed state, the water supply component supplies water to the liquid outlet pipe. When the valve assembly is in an open state, the water supply component supplies water to the first hot water exchange circuit and the liquid outlet pipe.

[0036] The main function of the first heat exchange circuit is to allow the cooling water to contact and exchange heat with the hydraulic oil returning from the paste filling pump in the heat exchange oil tank 2, thereby reducing the temperature of the returning hydraulic oil and ensuring that the low-temperature hydraulic oil flows back to the hydraulic oil tank 1; the main function of the liquid outlet pipe is to allow the cooling water to exchange heat with the hydraulic oil in the hydraulic oil tank 1, directly reducing the temperature of the hydraulic oil in the hydraulic oil tank 1; the main function of the water supply part is to supply cooling water to the first heat exchange circuit and the liquid outlet pipe; the main function of the heat dissipation water tank 7 is to reduce the temperature of the cooling water heated after heat exchange; the main function of the valve assembly is to control the flow direction of the cooling water. When the paste filling pump is running, the cooling water is in contact and exchange heat with the hydraulic oil in the heat exchange oil tank 2 and the hydraulic oil tank 1. During the intervals of the paste filling pump, since the hydraulic oil in the heat exchange oil tank 2 no longer flows, only the cooling water is controlled to flow into the liquid outlet pipe, directly exchanging heat with the hydraulic oil in the hydraulic oil tank 1, thereby maintaining the temperature of the hydraulic oil tank 1 stable. On the whole, the hydraulic oil tank cooling device of the present invention is provided with two sets of heat exchange paths, namely the first heat exchange circuit and the liquid outlet pipe fitting. The heat exchange efficiency is high, and the oil temperature in the hydraulic oil tank can be effectively controlled within a reasonable range. Moreover, according to the pulse working characteristics of the paste filling pump, when the hydraulic oil stops flowing during the pumping interval, the flow path of the cooling water can be quickly adjusted through the valve assembly, and the cooling water can be centrally supplied to the liquid outlet pipe fitting, thereby accelerating the heat exchange rate with the hydraulic oil in the hydraulic oil tank and maintaining the oil temperature in the hydraulic oil tank stable.

[0037] To further optimize the solution, the first heat exchange water circuit includes a second water collecting pipe 22 arranged at the top inner side of the heat exchange oil tank 2 and a third water collecting pipe 23 arranged at the bottom inner side of the heat exchange oil tank 2. Several first heat exchange water pipes 24 are connected between the second water collecting pipe 22 and the third water collecting pipe 23. The second water collecting pipe 22 is also connected to one end of the first liquid inlet pipe 5, and the other end of the first liquid inlet pipe 5 is connected to the water supply component. The third water collecting pipe 23 is connected to the third liquid outlet pipe 16, and the third liquid outlet pipe 16 is connected to the liquid inlet end of the heat dissipation water tank 7.

[0038] like Figure 1 and Figure 3 As shown, the water supply component passes the cooling water into the second water collecting pipe 22 through the first liquid inlet pipe 5, and the cooling water enters several second heat exchange water pipes 27, exchanges heat with the hydraulic oil in the heat exchange oil tank 2 through the outer walls of the second heat exchange water pipes 27. At the same time, the heated cooling water enters the third water collecting pipe 23 and flows toward the heat dissipation water tank 7 through the third liquid outlet pipe 16.

[0039] According to a further optimized solution, a plurality of third heat dissipation fins 25 are fixedly connected to the first water exchange pipe 24 .

[0040] According to a further optimized solution, the liquid outlet of the heat dissipation water tank 7 is connected to one end of the second liquid return pipe 11, and the other end of the second liquid return pipe 11 is connected to the water supply component.

[0041] like Figure 1As shown, the cooling water heated by heat exchange enters the heat dissipation water tank 7 and cools down by dissipating heat, and then flows back to the water supply component through the second return pipe 11 to realize the recycling of the cooling water.

[0042] To further optimize the solution, the liquid outlet pipe fittings include a water collecting tank 3 fixedly connected to the hydraulic oil tank 1, the top of the water collecting tank 3 is connected to one end of the second liquid inlet pipe 6, the other end of the second liquid inlet pipe 6 is connected to the first liquid inlet pipe 5, the bottom of the water collecting tank 3 is connected to several first liquid outlet pipes 4, the other ends of several first liquid outlet pipes 4 are respectively connected to one end of the second hot water exchange pipe 27, several second hot water exchange pipes 27 pass through the hydraulic oil tank 1, and the other end of the second hot water exchange pipe 27 is connected to the liquid inlet end of the heat dissipation water tank 7.

[0043] According to a further optimized solution, a plurality of second heat dissipation fins 21 are fixedly connected to the second heat exchange water pipe 27 .

[0044] To further optimize the solution, the end of several second water exchange water pipes 27 away from the water collecting tank 3 is connected to the first water collecting pipe 14, the water outlet end of the first water collecting pipe 14 is connected to the first return liquid pipe 10 through the water pump 13, the end of the first return liquid pipe 10 away from the water pump 13 is connected to the liquid inlet end of the heat dissipation water tank 7, and the third liquid outlet pipe 16 is connected to the first return liquid pipe 10.

[0045] like Figure 1 and Figure 2 As shown, some of the cooling water in the first liquid inlet pipe 5 flows into the water collection tank 3 through the second liquid inlet pipe 6. From there, it evenly flows into each of the first liquid outlet pipes 4 and further into each of the second heat exchange water pipes 27. The cooling water in the second heat exchange water pipes 27 exchanges heat with the hydraulic oil in the hydraulic oil tank 1 through the sidewalls, maintaining the oil temperature in the hydraulic oil tank 1. The cooling water in each of the second heat exchange water pipes 27 then flows into the first water collection pipe 14 and is pumped into the first return liquid pipe 10 by the water pump 13. The high-temperature cooling water flowing out of the third liquid outlet pipe 16 merges with the high-temperature cooling water in the first return liquid pipe 10 and flows together into the heat dissipation water tank 7.

[0046] In a further optimized solution, the valve assembly includes a solenoid valve 15 , which is disposed on the third liquid outlet pipe 16 .

[0047] like Figure 1 、 Figure 2 As shown, when the paste filling pump is intermittent and the solenoid valve 15 is in a closed state, the cooling water in the water supply component cannot continue to flow after passing through the first liquid inlet pipe 5, several first heat exchange water pipes 24 and the third liquid outlet pipe 16. Therefore, all the cooling water in the water supply component flows into the several second heat exchange water pipes 27 through the second liquid inlet pipe 6, the water collecting tank 3, etc., increasing the flow rate in the second heat exchange water pipes 27, improving the heat exchange efficiency with the hydraulic oil in the hydraulic oil tank 1, and maintaining the oil temperature in the hydraulic oil tank 1 stable.

[0048] To further optimize the solution, the water supply component includes a water pump 12, the water outlet end of the water pump 12 is connected to the end of the first liquid inlet pipe 5 away from the heat exchange oil tank 2, the water inlet end of the water pump 12 is connected to a water storage tank (not shown in the figure), and the end of the second return liquid pipe 11 away from the heat dissipation water tank 7 is connected to the water storage tank.

[0049] According to a further optimized solution, the bottom of the heat exchange oil tank 2 is connected to an oil return pipe 20 , and an oil outlet 26 is opened on the side wall of the heat exchange oil tank 2 , and the oil outlet 26 is connected to the interior of the hydraulic oil tank 1 .

[0050] like Figure 3 As shown, the hydraulic oil returning from the paste filling pump enters the heat exchange oil tank 2 through the oil return pipe 20 , and as the liquid level in the heat exchange oil tank 2 rises, it finally flows into the hydraulic oil tank 1 from the oil outlet 26 at the top.

[0051] To further optimize the solution, a bracket 8 is provided, and a plurality of fans 9 are fixedly connected to the bracket 8. The plurality of fans 9 are used to improve the heat dissipation efficiency of the heat dissipation water tank 7.

[0052] like Figure 1 As shown, a plurality of fans 9 blow air to the heat dissipation water tank 7, which lowers the temperature of the cooling water through heat exchange between the high-temperature cooling water and the flowing air, thereby preventing the high-temperature cooling water from flowing back into the water storage tank. The heat dissipation water tank 7 is a conventional device, and its structure and working principle will not be described in detail.

[0053] To further optimize the solution, an oil temperature sensor (not shown in the figure) is provided in the hydraulic oil tank 1.

[0054] To further optimize the solution, a control unit is further provided, which is electrically connected to the water pump 12, the solenoid valve 15, and the oil temperature sensor.

[0055] A control method for cooling a hydraulic oil tank of a paste filling pump, the operating steps comprising:

[0056] When the paste filling pump is running, the valve assembly is in an open state, and the water supply component allows water to flow into the first heat exchange circuit, so that the oil returning from the paste filling pump is cooled in the heat exchange tank 2 and flows back into the hydraulic oil tank 1. At the same time, the water supply component allows water to flow into the liquid outlet pipe fitting to directly cool the oil in the hydraulic oil tank 1;

[0057] When the paste filling pump is running, the control unit controls the synchronous operation of water pump 12, and solenoid valve 15 is open. High-temperature hydraulic oil returning from the filling pump enters heat exchange tank 2 through return oil pipe 20, where it exchanges heat with the cooling water in first heat exchange water pipe 24, lowering its temperature. The low-temperature hydraulic oil ultimately flows back into hydraulic tank 1 through oil outlet 26. Simultaneously, some of the cooling water enters second heat exchange water pipe 27, exchanging heat with the hydraulic oil in hydraulic tank 1 to maintain a stable oil temperature.

[0058] When the paste filling pump stops intermittently, the valve assembly is in a closed state, and the water supply component only allows water to flow into the liquid outlet pipe, continuously cooling the oil in the hydraulic oil tank 1.

[0059] When the paste filling pump stops, the hydraulic oil stops flowing, and the oil in the heat exchange tank 2 also stops flowing. At this time, the control unit immediately controls the solenoid valve 15 to close, and the water pump 12 only pumps cooling water into the second heat exchange water pipe 27, speeding up the water flow in the second heat exchange water pipe 27, improving the heat exchange efficiency with the hydraulic oil in the hydraulic oil tank 1, and ensuring the oil temperature in the hydraulic oil tank 1 is stable.

[0060] Example 2:

[0061] The only difference between this embodiment and the first embodiment is that a plurality of air ducts 18 are opened between two opposite side walls of the heat exchange oil tank 2 , an oil duct 19 is formed between two adjacent air ducts 18 inside the heat exchange oil tank 2 , and the first heat exchange water pipe 24 passes through the oil duct 19 .

[0062] According to a further optimized solution, a plurality of first heat dissipation fins 17 are fixedly connected to the side walls of the air duct 18 .

[0063] like Figure 1 and Figure 3 As shown, the heat sink 7 is fixedly connected to the heat exchange oil tank 2 and positioned between the latter and the fan 9. Air from the fan 9 passes through the heat sink 7 and is then exhausted through a plurality of air ducts 18. During this airflow, it first exchanges heat with the heat sink 7, lowering the cooling water temperature. The air then contacts the first heat sink fins 17, exchanging heat with the hydraulic oil in the oil passages 19, further improving the cooling efficiency of the hydraulic oil.

[0064] Example 3:

[0065] The only difference between this embodiment and the first embodiment is that the top and bottom of the side of the bracket 8 away from the heat dissipation water tank 7 are respectively horizontally fixedly connected with a slide groove 28, a filter frame 29 is slidably connected between the two slide grooves 28, and a filter is fixedly connected inside the filter frame 29.

[0066] like Figure 1 and Figure 6 As shown, the main function of the filter is to prevent impurities in the air from accumulating on the surface of the heat dissipation water tank 7, maintain the air flow speed, and avoid reducing the heat dissipation efficiency in the heat dissipation water tank 7. By providing the structure of the chute 28, the filter can be quickly replaced.

[0067] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0068] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
