Technical Field
[0001] This utility model relates to the technical field of compressor cooling devices, and more specifically to a cooling device for an oil refining compressor. Background Technology
[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system and is one of the commonly used pieces of equipment in oil refining and chemical industries. There are many types of compressors, but all of them require bearings. Because bearings rotate at high speeds continuously, they generate a lot of heat. If the heat is not dissipated in time, it will accelerate their wear. Therefore, cooling devices are usually used to dissipate heat.
[0003] In the process of developing this application, the following problems were found with this technology: when filtering impurities in the air through a filter screen, if there are too many impurities on the filter screen, staff need to clean it in a timely manner, otherwise it will affect normal use. Manually cleaning the filter screen will easily increase the workload and fatigue of the staff. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cooling device for an oil refining compressor to solve the problem of needing to manually clean the filter screen in the prior art.
[0005] This utility model provides the following technical solution: a cooling device for an oil refining compressor, including a base, a compressor body, a bearing cavity, a bearing, and a fixed box, and further including a cooling component, a moving component, a cleaning component, and a locking component. The compressor body and the fixed box are both connected to the base by bolts. The bearing cavity is located inside the compressor body, and the bearing is located inside the bearing cavity. The cooling component is located inside the fixed box and connected to the bearing cavity. Several air inlets are provided on one side of the fixed box, and filters are provided in each of the air inlets. The moving component is located directly above the air inlets and connected to the fixed box. The cleaning component is located on the moving component, and the locking component is located on the moving component and locks the cleaning component.
[0006] Furthermore, the cooling assembly includes a fan, an inlet pipe, and an outlet pipe. The fan is fixedly installed at the bottom of the fixed box. One end of the inlet pipe is fixedly connected to the outlet pipe of the fan, and the other end passes through the fixed box and the compressor body and is fixedly connected to the bearing cavity. One end of the outlet pipe passes through the compressor body and is fixedly connected to the bearing cavity.
[0007] Furthermore, the moving component includes a connecting box, a motor, a reciprocating lead screw, and a slider. One side of the connecting box is fixedly installed on the side of the fixed box. The connecting box is located above several air inlets. The bottom of the connecting box is open. The fixed end of the motor is fixedly installed inside the connecting box. One end of the reciprocating lead screw is fixedly connected to the output end of the motor. The other end of the reciprocating lead screw is rotatably connected to the inner wall of the connecting box. The slider is sleeved on the reciprocating lead screw and slides against the inner wall of the connecting box.
[0008] Furthermore, the movable component also includes a fixing groove, a limiting groove, and a connecting hole. The fixing groove is opened on one side of the slider, the limiting groove is opened inside the fixing groove, and the connecting hole is opened on one side of the slider and located above the fixing groove. The connecting hole communicates with the limiting groove.
[0009] Furthermore, the cleaning assembly includes a horizontal plate and a roller-shaped adhesive plate, the roller-shaped adhesive plate being rotatably connected to the bottom of the horizontal plate.
[0010] Furthermore, the locking assembly includes a movable plate, a spring, a cord, and a fixing block. The spring and the movable block are disposed in a limiting groove. One end of the spring is fixedly connected to the top of the limiting groove, and the other end is fixedly connected to the movable block. The movable block slides in conjunction with the limiting groove. One end of the cord is fixedly connected to the movable block, and the other end enters the connecting hole from the limiting groove and extends from the connecting hole to the outside of the slider. The fixing block is fixedly connected to the cord located outside the slider.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. This utility model uses a motor to drive a reciprocating lead screw to rotate. Due to the limiting effect of the inner wall of the connecting box, the slider reciprocates along the inner wall of the connecting box. The movement of the slider causes the horizontal plate and the roller-shaped adhesive plate, which are fixed by the locking component, to move synchronously. This causes the moving roller-shaped adhesive plate to roll on the surface of the filter screen. The rolling roller-shaped adhesive plate adheres to the impurities on the filter screen, and the reciprocating roller-shaped adhesive plate cleans the impurities on the filter screen. No manual cleaning is required, saving labor costs for workers.
[0013] 2. In this utility model, the worker pulls the fixing block, which in turn pulls the rope, causing the moving plate to move upward along the limiting groove. The spring is compressed by the moving plate, at which point the moving plate no longer presses against the horizontal plate on the roller-shaped adhesive plate. The worker can then remove the roller-shaped adhesive plate. When the replacement roller-shaped adhesive plate is located in the limiting groove, the worker stops pulling the fixing block, and the spring rebounds, causing the moving plate to move along the limiting groove until it abuts against the horizontal plate on the roller-shaped adhesive plate. As the moving plate moves and pulls the rope, the rope pulls the fixing block. When the moving plate contacts the horizontal plate on the roller-shaped adhesive plate, the fixing block contacts the slider, facilitating the worker's replacement of the roller-shaped adhesive plate.

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0023] Figures 1 to 7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 7 The present invention will be further described below.
[0024] This utility model discloses a cooling device for an oil refining compressor, including a base 1, a compressor body 2, a bearing cavity 3, a bearing 4, and a fixed box 5. It also includes a cooling assembly 6, a moving assembly 7, a cleaning assembly 8, and a locking assembly 9. The compressor body 2 and the fixed box 5 are both connected to the base 1 by bolts. The bearing cavity 3 is located inside the compressor body 2, and the bearing 4 is located inside the bearing cavity 3. The cooling assembly 6 is located inside the fixed box 5 and connected to the bearing cavity 3. Several air inlets 11 are provided on one side of the fixed box 5, and each air inlet 11 is equipped with a filter screen 10. The moving assembly 7... The cleaning component 8 is located directly above several air inlets 11 and connected to the fixed box 5. The cleaning component 8 is located on the moving component 7, and the locking component 9 is located on the moving component 7 and locks the cleaning component 8. The cooling component 6 includes a fan 601, an air inlet pipe 602, and an air outlet pipe 603. The fan 601 is fixedly installed at the bottom inside the fixed box 5. One end of the air inlet pipe 602 is fixedly connected to the air outlet pipe 603 of the fan 601, and the other end passes through the fixed box 5 and the compressor body 2 and is fixedly connected to the bearing cavity 3. One end of the air outlet pipe 603 passes through the compressor body 2 and is fixedly connected to the bearing cavity 3.
[0025] In this embodiment, when the compressor body 2 operates, the bearing 4 inside the compressor body 2 operates, and the heat generated by the operation of the bearing 4 is released into the bearing cavity 3. The fan 601 starts, causing air to pass through the air inlet, through the filter screen 10, and through which impurities in the air are filtered. The filtered air is then delivered by the fan 601 to the air inlet pipe 602 and enters the bearing cavity 3 from the air inlet pipe 602. This carries the heat dissipated by the bearing 4 within the bearing cavity 3 into the air inlet / outlet pipe 603, thereby cooling the operating bearing 4. The air outlet pipe 603 is externally connected to a heat recovery device. Heat recovery is performed through an external heat recovery system. When the work is finished, the compressor body 2 will no longer work. At this time, the moving component 7 drives the cleaning component 8, which is fixed by the locking component 9, to move. The moving cleaning component 8 contacts the surface of the filter screen 10 and cleans the impurities on the surface of the filter screen 10. When the locking component 9 does not fix the cleaning component 8, the cleaning component 8 is manually removed from the moving component 7 and replaced with a new cleaning component 8, which is then fixed by the locking component 9. The fan 601 is existing technology and will not be explained here. The filter screen 10 protrudes from the air outlet.
[0026] Specifically, the moving component 7 includes a connecting box 701, a motor 702, a reciprocating lead screw 703, and a slider 704. The connecting box 701 is fixedly mounted on one side of the fixed housing 5, located above several air inlets 11. The bottom of the connecting box 701 is open. The fixed end of the motor 702 is fixedly mounted inside the connecting box 701. One end of the reciprocating lead screw 703 is fixedly connected to the output end of the motor 702, and the other end of the reciprocating lead screw 703 is rotatably connected to the inner wall of the connecting box 701. The slider 704 is fitted onto the reciprocating lead screw 704. The moving assembly 7 also includes a fixed groove 705, a limiting groove 706, and a connecting hole 707. The fixed groove 705 is opened on one side of the slider 704, the limiting groove 706 is opened in the fixed groove 705, and the connecting hole 707 is opened on one side of the slider 704 and located above the fixed groove 705. The connecting hole 707 communicates with the limiting groove 706. The cleaning assembly 8 includes a horizontal plate 801 and a roller-shaped adhesive plate 802. The roller-shaped adhesive plate 802 is rotatably connected to the bottom of the horizontal plate 801.
[0027] In this embodiment, when the cleaning component 8 is driven by the moving component 7 to clean the filter screen 10, the horizontal plate 801 is initially located in the limiting groove 706, and the locking component 9 limits the horizontal plate 801, preventing it from disengaging from the limiting groove 706. The motor 702 starts, driving the reciprocating screw 703 to rotate. Due to the limiting effect of the inner wall of the connecting box 701, the slider 704 reciprocates along the inner wall of the connecting box 701. The movement of the slider 704 causes the horizontal plate 801 and the roller-shaped adhesive plate 802, which are fixed by the locking component 9, to move synchronously. This causes the moving roller-shaped adhesive plate 802 to roll on the surface of the filter screen 10, adhering to impurities on the filter screen 10. The reciprocating movement of the roller-shaped adhesive plate 802 cleans the impurities on the filter screen 10, eliminating the need for manual cleaning and saving labor. Once cleaning is complete... When the roller-shaped adhesive plate 802 needs to be replaced, the worker moves the roller-shaped adhesive plate 802 upwards. The roller-shaped adhesive plate 802 drives the connected horizontal plate 801 to move synchronously. The horizontal plate 801 moves along the limiting groove 706 and moves to the connection between the limiting groove 706 and the fixed groove 705. The worker then manually pulls the roller-shaped adhesive plate 802, and the horizontal plate 801 moves from the connection between the limiting groove 706 and the fixed groove 705 into the fixed groove 705. The plate is then removed through the fixed groove 705 for replacement. The worker places the horizontal plate 801 into the fixed groove 705 and moves it along the fixed groove 705 to the connection between the fixed groove 705 and the limiting groove 706. Due to its own gravity, the horizontal plate 801 moves along the limiting groove 706 towards the bottom of the limiting groove 706. At this point, the worker uses the locking component 9 to fix the horizontal plate 801, thus fixing the roller-shaped adhesive plate 802 in the limiting groove 706.
[0028] Specifically, the locking assembly 9 includes a movable plate 901, a spring 902, a rope 903, and a fixing block 904. The spring 902 and the movable block are disposed in the limiting groove 706. One end of the spring 902 is fixedly connected to the top of the limiting groove 706, and the other end is fixedly connected to the movable block. The movable block slides in the limiting groove 706. One end of the rope 903 is fixedly connected to the movable block, and the other end enters the connecting hole 707 from the limiting groove 706 and extends from the connecting hole 707 to the outside of the slider 704. The fixing block 904 is fixedly connected to the rope 903 located outside the slider 704.
[0029] In this embodiment, initially, spring 902 is in a released state, moving plate 901 abuts against the horizontal plate 801 on roller-shaped adhesive plate 802, rope 903 is in a taut state, and fixing block 904 abuts against slider 704. When roller-shaped adhesive plate 802 needs to be replaced, the worker pulls fixing block 904, which pulls rope 903. Rope 903 pulls moving plate 901 upward along limiting groove 706. At this time, spring 902 is compressed by moving plate 901, and moving plate 901 no longer compresses the horizontal plate 801 on roller-shaped adhesive plate 802. The operator removes the roller-shaped adhesive plate 802. When the replacement roller-shaped adhesive plate 802 is located in the limiting groove 706, the operator stops pulling the fixing block 904. At this time, the spring 902 rebounds, causing the moving plate 901 to move along the limiting groove 706, so that the moving plate 901 abuts against the horizontal plate 801 on the roller-shaped adhesive plate 802. When the moving plate 901 moves, it pulls the rope 903, which in turn pulls the fixing block 904. When the moving plate 901 contacts the horizontal plate 801 on the roller-shaped adhesive plate 802, the fixing block 904 contacts the slider 704, making it convenient for the operator to replace the roller-shaped adhesive plate 802.
[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
