Description

Technical Field

[0001] The present invention relates to the technical field of oil coolers, and more specifically, the present invention is an impurity filtering device for an oil cooler. Background Art

[0002] An oil cooler, also known as a cold oil machine, according to the principle of the refrigeration system, a low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs the heat of the oil and evaporates into a low-temperature and low-pressure gas. During the evaporation process, the temperature of the refrigerant remains unchanged. The low-temperature and low-pressure gaseous refrigerant enters the compressor, is compressed by the compressor, and is compressed into a high-temperature and high-pressure gas. Then it enters the condenser and exchanges heat with the medium in the room. Part of the heat of the high-temperature and high-pressure gas is absorbed by the medium, and the temperature of the medium rises. The refrigerant releases heat and becomes a high-temperature and high-pressure liquid. The temperature remains unchanged during the condenser process. Then it enters the expansion valve for throttling, which is a process of rapidly reducing the temperature. The refrigerant after this process then enters the evaporator for heat exchange and evaporation, thus realizing the entire process of the refrigeration system. Among them, the existing patent with the publication number: CN213885283U discloses a filtering device and an oil cooler for an oil cooler, including: a filter having an inlet and an outlet, an inlet pipeline communicating with the inlet, and an outlet pipeline communicating with the outlet, so that the heat exchange medium passes through the filter through the inlet pipeline and flows out from the outlet pipeline, a branch pipeline, both ends of which are respectively communicated with the inlet pipeline and the outlet pipeline, a pressure sensor installed on the inlet pipeline and close to the inlet, and an electromagnetic switch valve including a first electromagnetic switch valve and a second electromagnetic switch valve. Through the filtering device of the oil cooler, when the blockage degree of the filter is relatively large and affects the flow rate of the heat exchange medium passing through the heat exchange module, the heat exchange medium no longer passes through the filter and flows into the heat exchange module through the branch pipeline, which is beneficial to timely dissipate the waste heat of the heating component.

[0003] However, in actual use, there are still some disadvantages. For example, during the operation of the current oil cooler filtering equipment, the filtering equipment cannot remove the impurities adhering to its own interior in real time. During subsequent cleaning, the equipment needs to be paused to deeply clean the filtering equipment separately. The process is relatively cumbersome and cannot meet the requirement of real-time cleaning. As a result, after the oil cooler is paused, the kinetic energy consumption required for restarting is relatively large, which affects the overall energy consumption required by the equipment and has an impact on the working efficiency and economic benefits of the entire equipment. Summary of the Invention

[0004] To overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an impurity filtering device for an oil cooler. By setting a filtering side plate, an installation component and a filtering box, and using their mutual cooperation, when the filtering side plate has been performing long-term filtering work, the filtering side plate can be directly removed from the insertion opening on one side of the side top plate for cleaning and replacement. Subsequently, the fixing bolt can be moved from the threaded hole on one side of the side panel towards one side of the fixing support plate, so that one end of the fixing bolt abuts against the surface of the fixing support plate, and then the fixing support plate and the fixing rod are slid towards one side. At this time, the fixing bent rod on the side of the fixing rod will drive the connecting seat, the fixing spring and the rubber cushion plate on one side of it to move towards the surface of the filtering side plate, thereby applying a lateral force to the whole, making the fit between the whole and the side top plate better, further ensuring the fixing effect between the filtering side plate and the side top plate, so as to achieve the effect of detachable replacement. And during this period, there is no need to stop the equipment, ensuring the sustainable operation of the equipment and further improving the working efficiency of the equipment. By setting an arc-shaped chute, a fixing slider and a self-locking hole, since the overall shape of the fixing slider is cylindrical, the friction between its side and the arc-shaped chute is small when it slides inside the arc-shaped chute, thereby ensuring the smoothness of their movement during the process, further improving the flexibility of the fixing slider. At the same time, it can be ensured that when the fixing slider moves to the position of the self-locking hole, it can contact the wear-resistant side plates on both sides of the inner wall of the self-locking hole and squeeze the wear-resistant side plates on both sides of it, so as to ensure that when the fixing slider moves into the position inside, it can achieve the self-locking effect, thereby further improving the stability effect of the multiple filtering side plates on the inner surface of the equipment, so as to solve the problems raised in the above-mentioned background technology.

The overall material of the rubber cushion plate 894 is rubber material. The center of the rubber cushion plate 894 and the central axis of the fixed spring 893 are on the same horizontal line.

[0035] The specific implementation method is as follows: Since the overall material of the rubber cushion plate 894 is rubber material, when it contacts the filter side plate 15 as a whole, it can reduce the collision degree between the two, and at the same time ensure that the pressure of the fixed spring 893 on one side of the rubber cushion plate 894 can be effectively transmitted to the surface of the filter side plate 15, so as to effectively attach the rubber cushion plate 894 to the outer surface of the filter side plate 15.

The overall shape of the fixed slider 1092 is cylindrical.

[0037] The specific implementation method is as follows: Since the overall shape of the fixed slider 1092 is cylindrical, when it slides inside the arc-shaped sliding groove 1094, the friction between its side and the arc-shaped sliding groove 1094 is small, so as to ensure the smoothness of the two during the movement process, further improve the flexibility of the fixed slider 1092, and at the same time ensure that when the fixed slider 1092 moves to the position of the self-locking hole 1095, it can contact the wear-resistant side plates 1096 on both sides of the inner wall of the self-locking hole 1095 and squeeze the two wear-resistant side plates 1096 on both sides, so as to ensure that when the fixed slider 1092 moves into the position inside, it can achieve the self-locking effect.

[0038] The working principle of the present invention:

[0039] Step 1: First, the operator normally assembles each component of the device and then normally starts the device.

[0040] Step 2: First, the operator normally starts the oil cooler 1. At this time, the cooling oil passes through the oil delivery pipeline 9 at one end of the cooling component 11 and enters the filter tank 6. After being filtered by the multi-layer filter side plates 15 inside the filter tank 6, it re-enters the inside of the cooling component 11 through the oil return pipeline 12 for reuse. Then, after the filter side plates 15 have been performing long-term filtering work, the filter side plates 15 can be directly disassembled from the insertion opening 82 on one side of the side top plate 81 for cleaning and replacement. Subsequently, at the same time, the fixing bolts 87 can be moved from the threaded holes 86 on one side of the side panel 85 towards one side of the fixing support plate 89, so that one end of the fixing bolt 87 abuts against the surface of the fixing support plate 89, thereby sliding the fixing support plate 89 and the fixing rod 88 towards one side. At this time, the fixing bent rod 891 on the side of the fixing rod 88 will drive the connecting seat 892, the fixing spring 893, and the rubber cushion plate 894 on one side of it towards the surface of the filter side plate 15, thereby applying a lateral force to the whole, making the fit between the whole and the side top plate 81 better, and further ensuring the fixing effect between the filter side plate 15 and the side top plate 81. At this time, the driving gear 101 is rotated through the fixing rotating handle 103, so that it drives the linkage gear 104 to rotate synchronously. Then, the fixing rotating disk 109 on the linkage gear 104 drives the fixing slider 1092 at its bottom to slide inside the arc-shaped chute 1094. It can be ensured that when the fixing slider 1092 moves to the position of the self-locking hole 1095, it can contact the wear-resistant side plates 1096 on both sides of the inner wall of the self-locking hole 1095 and squeeze the two wear-resistant side plates 1096 on both sides of it, so as to ensure that the whole fixing slider 1092 achieves a self-locking effect. Finally, the process of the device completing the replacement work of the filter side plate 15 is completed.

[0041] Step 3: First, the operator normally shuts down the device. Then, the operator checks whether the fixity between the components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.

[0042] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change;

[0043] Second: In the accompanying drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. For other structures, reference may be made to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0044] Finally: The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
