Abstract
Description
Technical Field
[0001] This utility model relates to the field of compressors, and more particularly to an automatic temperature-controlled screw compressor. Background Technology
[0002] Screw compressors are commonly used gas compression devices, widely applied in industrial production, refrigeration, and air compression. During operation, screw compressors generate significant heat due to gas compression and friction between mechanical parts. If this heat cannot be dissipated effectively, the compressor temperature will rise continuously. Excessive temperature can negatively impact compressor performance and lifespan. For example, it can reduce the viscosity of the lubricating oil, leading to poor lubrication, increased wear on mechanical parts, and in severe cases, even damage to components; it can also affect the compressor's sealing performance, causing gas leaks and reducing compressor efficiency.
[0003] In the prior art, some screw compressors typically use coolant to cool their internal components during operation. However, the coolant may contain particulate impurities, which can affect the operation of internal machinery. To address this issue, an automatic temperature-controlled screw compressor is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an automatic temperature-controlled screw compressor, which aims to improve the existing technology that uses coolant to cool the internal parts, but the coolant contains particulate impurities that affect the operation of the internal machinery.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic temperature-controlled screw compressor includes a body, an oil inlet pipe fixedly connected to the front end of the body, sliding grooves on both the left and right sides of the inside of the oil inlet pipe, a retaining plate slidably connected to the inner wall of the sliding groove, a push plate fixedly connected to the outside of the retaining plate, a limit post fixedly connected to the side of the retaining plate away from the push plate, a reset component provided on the outside of the retaining plate, a filter plate detachably connected to the inside of the oil inlet pipe, and an adjustment component provided at the bottom of the body.
[0007] As a further description of the above technical solution:
[0008] The reset assembly includes a spring, one end of which is fixedly connected to the outside of the limiting post. Two movable grooves are opened on the rear side of the oil inlet pipe. A stop plate is fixedly connected to the inner wall of the movable groove. Slots are opened on both the left and right sides of the filter plate.
[0009] As a further description of the above technical solution:
[0010] One end of the spring away from the limiting post is fixedly connected to the inside of the abutment plate, and the outside of the push plate is slidably connected to the outer wall of the abutment plate;
[0011] As a further description of the above technical solution:
[0012] The push plate is slidably connected to the inner wall of the movable groove, and the outer side of the locking plate is engaged with the inner wall of the locking groove.
[0013] As a further description of the above technical solution:
[0014] An air outlet is fixedly connected to the bottom of the machine body, and an air inlet is fixedly connected to the top of the machine body;
[0015] As a further description of the above technical solution:
[0016] The adjustment assembly includes multiple fixed columns. The top of each fixed column is fixedly connected to the inside of the air outlet. A cavity is opened inside the fixed column. A second spring is fixedly connected to the inner wall of the top of the cavity. A limit plate is fixedly connected to the bottom of the second spring.
[0017] As a further description of the above technical solution:
[0018] The bottom of the limiting plate is fixedly connected to a hanging rod, and the bottom of the multiple hanging rods is fixedly connected to a blocking plate, the top of the blocking plate being in contact with the bottom inner wall of the air outlet;
[0019] As a further description of the above technical solution:
[0020] The inner wall of the limiting plate is slidably connected to the inner wall of the cavity, and the outer side of the hanging rod is slidably connected to the bottom through hole of the fixed column.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when the filter plate is placed into the oil inlet pipe and the slot is aligned with the plate, the push plate is released, and the spring quickly releases its elastic potential energy, pulling the limit post to reset. This causes the plate to reset and unfold to both sides, tightly abutting against the inner wall of the slot, thus achieving rapid fixation of the filter plate. Compared with the traditional filter plate installation method, there is no need for cumbersome screw tightening operations, which greatly saves installation time and improves work efficiency. At the same time, this simple and reliable installation structure also reduces the probability of problems such as poor sealing caused by improper installation.
[0023] 2. In this utility model, as the wind force acts, the blocking plate moves downward under pressure, and the limiting plate slides in the cavity through the hanging rod, stretching the second spring. The greater the wind force, the greater the stretch of the second spring, the greater the downward distance of the blocking plate, the larger the exhaust area of the air outlet, and the faster the exhaust speed. Conversely, when the wind force decreases, the second spring releases its elastic potential energy, pulling the limiting plate and the blocking plate back to their original positions, reducing the exhaust area and the exhaust speed. This allows the compressor to maintain good heat dissipation under different operating conditions, ensuring the stability of the compressor's internal temperature, effectively improving the compressor's operational stability and service life, and avoiding equipment failure caused by excessive temperature.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1 to 3This utility model provides an embodiment of an automatic temperature-controlled screw compressor, including a body 1, which is the core of the entire automatic temperature-controlled screw compressor. An oil inlet pipe 2 is fixedly connected to the front end of the body 1. The oil inlet pipe 2 is the key channel for coolant to enter the body 1, ensuring that the coolant can enter the body 1 at a suitable flow rate and volume to meet the heat dissipation requirements during compressor operation. As the body 1 operates, the coolant cools the interior, and then the liquid is discharged from the outlet on the left side of the body 1. Sliding grooves 3 are provided on both the left and right sides of the interior of the oil inlet pipe 2. The sliding grooves 3 are symmetrically distributed on the left and right sides of the interior of the oil inlet pipe 2. Their shape is a cuboid groove, and their length is adapted to the length of the specific working area of the oil inlet pipe 2.
[0032] A retaining plate 4 is slidably connected to the inner wall of the sliding groove 3. The width and depth of the sliding groove 3 are slightly larger than the corresponding dimensions of the retaining plate 4, which ensures that the retaining plate 4 can slide freely within it, while also providing a certain limiting effect to prevent the retaining plate 4 from shifting or shaking during the sliding process. A push plate 5 is fixedly connected to the outside of the retaining plate 4. The push plate 5 facilitates the operation of the retaining plate 4 by the operator. By pushing the push plate 5, the retaining plate 4 can be easily moved to slide within the sliding groove 3.
[0033] A limiting post 6 is fixedly connected to the side of the clamping plate 4 away from the push plate 5. A reset assembly is provided on the outside of the clamping plate 4, which includes a spring 7. When the operator pushes the push plate 5, causing the clamping plate 4 to slide, the limiting post 6 moves accordingly, thereby stretching the spring 7 and allowing the spring 7 to store elastic potential energy. One end of the spring 7 is fixedly connected to the outside of the limiting post 6. Two movable grooves 8 are opened on the rear side of the oil inlet pipe 2. The limiting post 6 is cylindrical, and its diameter is adapted to the width of the movable groove 8. Its length is moderate, which can ensure free sliding within the movable groove 8 and effective reset under the action of the spring 7.
[0034] The push plate 5 is externally slidably connected to the inner wall of the movable groove 8. A stop plate 9 is fixedly connected to the inner wall of the movable groove 8. The stop plate 9 is fixedly connected inside the movable groove 8. Its function is to cooperate with the spring 7 and the push plate 5 to achieve the reset and fixation function of the locking plate 4. During the pushing of the locking plate 4, the push plate 5 can slide within the movable groove 8, and its outer surface can slide along the outer wall of the stop plate 9, providing stable guidance and support for the entire operation. The end of the spring 7 furthest from the limiting post 6 is fixedly connected to the inside of the stop plate 9. The main function of the stop plate 9 is to cooperate with the spring 7 and the push plate 5. When the spring 7 is stretched, the stop plate 9 provides a fixed support point for the spring 7, ensuring that the spring 7 can effectively store elastic potential energy.
[0035] The push plate 5 is externally slidably connected to the outer wall of the abutment plate 9. During the sliding process of the push plate 5, the outer side of the push plate 5 can slide along the outer wall of the abutment plate 9. The abutment plate 9 provides a stable guide for the sliding of the push plate 5, ensuring the accuracy and stability of the push plate 5 during the sliding process. The connection between the abutment plate 9 and the movable groove 8 and other related components is firm and reliable, and can withstand the various forces generated during operation.
[0036] A filter plate 10 is detachably connected inside the oil inlet pipe 2. The filter plate 10 is used to filter impurities in the coolant. When the operator releases the push plate 5, the spring 7 releases its elastic potential energy, pulling the limit post 6 back to its original position, which in turn drives the retaining plate 4 to return to its original position, thus realizing the automatic fixing function of the filter plate 10. The filter plate 10 has slots 11 on both its left and right sides. The outer side of the retaining plate 4 engages with the inner wall of the slot 11. When the retaining plate 4 engages with the slot 11, it provides sufficient friction and clamping force to ensure the filter plate 10 is firmly fixed inside the oil inlet pipe 2.
[0037] Reference Figure 4 An air outlet 12 is fixedly connected to the bottom of the unit 1, ensuring that the exhaust demand during compressor operation is met. An air inlet 19 is fixedly connected to the top of the unit 1, and an adjustment assembly is provided at the bottom of the unit 1. The adjustment assembly includes multiple fixed columns 13, the top of which is fixedly connected to the inside of the air outlet 12. The fixed column 13 is cylindrical, and a cavity 14 is opened inside the fixed column 13. A second spring 15 is fixedly connected to the inner wall of the top of the cavity 14. A limit plate 17 is fixedly connected to the bottom of the second spring 15, and a hanging rod 16 is fixedly connected to the bottom of the limit plate 17. A blocking plate 18 is fixedly connected to the bottom of the multiple hanging rods 16. When the blocking plate 18 moves downward under the action of wind force, the second spring 15 is stretched and stores elastic potential energy. When the wind force decreases, the second spring 15 releases elastic potential energy, pulling the limit plate 17 and the blocking plate 18 back to their original positions, thereby realizing automatic adjustment of the exhaust speed.
[0038] The top of the blocking plate 18 contacts the bottom inner wall of the air outlet 12. When the blocking plate 18 moves downward under the action of wind, the limiting plate 17 slides in the cavity 14 and stretches the second spring 15. The exhaust speed is adjusted by the elastic action of the second spring 15. The inner wall of the limiting plate 17 is slidably connected to the inner wall of the cavity 14. When the blocking plate 18 moves downward under the action of wind, the limiting plate 17 slides downward in the cavity 14 and stretches the second spring 15. When the wind force decreases, the limiting plate 17 slides upward under the action of the second spring 15, causing the blocking plate 18 to return to its original position.
[0039] The limiting plate 17 plays a key role in connecting and transmitting force in the adjustment assembly, ensuring the smooth progress of the entire adjustment process. The external sliding connection of the hanger 16 is to the bottom through hole of the fixed column 13. Through the connection of the hanger 16, the linkage between the limiting plate 17 and the blocking plate 18 is realized. When the limiting plate 17 slides in the cavity 14, it can drive the blocking plate 18 to move synchronously through the hanger 16, thereby realizing the adjustment of the exhaust area of the air outlet 12. When the air inside the unit 1 is discharged from the air outlet 12, the air will squeeze the blocking plate 18 downward, causing the blocking plate 18 to move downward under force. Through the hanger 16, the limiting plate 17 slides in the cavity 14, stretching the spring 15, thereby automatically adjusting the exhaust area of the air outlet 12 according to the wind force, realizing the adjustment of the exhaust speed.
[0040] Working principle: First, install the body 1 in a suitable position, then press the push plate 5 simultaneously. As the push plate 5 moves, the clamping plate 4 slides on the inner wall of the sliding groove 3. At the same time, the limiting post 6 on the rear side of the clamping plate 4 slides on the inner wall of the movable groove 8. At this time, the spring 7 is stretched by force, and the outer side of the clamping plate 4 slides along the outer side of the abutment plate 9. Then, the filter plate 10 is placed inside the oil inlet pipe 2, and the clamping groove 11 is placed outside the clamping plate 4. Then, the push plate 5 is released. At this time, the spring 7 is no longer under force. During the reset process, the limiting post 6 will be pulled to reset. At this time, the clamping plate 4 will also be forced to reset and unfold to both sides, so that it can abut against the inner wall of the clamping groove 11, thereby fixing the filter plate 10 inside the oil inlet pipe 2. Then, when adding coolant, it can filter the impurities inside.
[0041] As the machine body 1 operates, air enters the interior of the machine body 1 through the air inlet 19 and is then discharged through the air outlet 12. At this time, the air will push the block plate 18 downward, and the block plate 18 will move downward under force. The limiting plate 17 will move downward against the inner wall of the cavity 14 under force. At this time, the second spring 15 will be stretched under force, which can adjust the exhaust speed according to the wind force, thereby cooperating with the coolant to cool the interior.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
