Description

Technical Field

[0001] This utility model belongs to the field of replacement device technology, specifically a replacement device for an air source heat pump jet enthalpy booster filter. Background Technology

[0002] In a jet enthalpy enhancement system, the steam in the make-up air circuit needs to enter the compression chamber through the compressor's make-up air port. If the steam carries impurities (such as metal shavings, particulate matter, etc.), it may cause internal wear, blockage, or performance degradation of the compressor. The make-up air filter reduces the risk of failure of critical components by intercepting such impurities. However, the filter needs to be replaced regularly to ensure its filtering and interception effect.

[0003] The filter 103 consists of a filter tube filled with multiple layers of filter plates and fixed flanges at both ends by welding. The filter 103 is connected to the flanges on the evaporator gas supply pipe 101 and the compressor inlet pipe 102 respectively through the two flanges. A circular sealing gasket is provided between the flanges on the evaporator gas supply pipe 101 and the compressor inlet pipe 102, so that the bolts pass through the bolt holes on the flanges and the nuts are tightened on the bolts to complete the connection between the filter 103 and the evaporator gas supply pipe 101 and the compressor inlet pipe 102.

[0004] However, the above installation method requires first connecting the sealing gasket and filter flange to the evaporator gas supply pipe flange, and then manually pressing the sealing gasket to ensure that the gasket, filter flange, and evaporator gas supply pipe flange are in contact. Then, the filter flange and sealing gasket are installed. This requires multiple people to cooperate, and the operation steps are relatively cumbersome, resulting in low installation efficiency and affecting the use of the compressor. Therefore, in order to address the above problems, an air source heat pump jet enthalpy injection filter replacement device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a replacement device for the air source heat pump jet enthalpy booster filter is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The air source heat pump jet enthalpy enhancement and gas replenishment filter replacement device of this utility model includes a fixing plate; a mounting groove is opened on one side of the fixing plate, a double-headed threaded rod is rotatably connected to the inner side wall of the mounting groove, and an adjusting plate is threaded to both ends of the outer wall of the double-headed threaded rod.

[0007] The adjusting plate is equipped with an adjusting mechanism, which includes a limiting plate fixedly connected to one side of the adjusting plate. A limiting groove is formed on one side of the limiting plate. A guide rod is fixedly connected to the inner wall of the limiting groove. A transmission block is slidably connected to the outer wall of the guide rod. A pressing block is fixedly connected to one side of the transmission block. One end of the transmission block is elastically connected to the inner wall of the limiting groove through a first spring. By setting up the adjusting mechanism, it is easy to limit the sealing gasket and the flange on the filter together, so as to facilitate subsequent docking with the flange installed on the evaporator gas supply pipe and the flange installed on the compressor inlet pipe, simplifying the operation steps and improving the replacement efficiency.

[0008] Preferably, a groove is provided on one side of the limiting plate, and a limiting block is slidably connected in the groove. One end of the limiting block is elastically connected to the inner wall of the groove through a second spring, and the other end of the limiting block extends out of the groove. With the setting of the groove, the second spring and the limiting block, it is convenient to position the sealing gasket that is limited together with the flange on the filter, so that the angle of the sealing gasket does not need to be adjusted during subsequent installation, thereby further improving the replacement efficiency.

[0009] Preferably, a toggle block is fixedly connected to one side of the outer wall of the limiting block, and the outer wall of the limiting block is provided with a wear-resistant layer. By setting the toggle block, the limiting block can be moved by pulling the toggle block, avoiding the limitation block being difficult to move due to the smooth outer wall of the limiting block.

[0010] Preferably, the inner wall of the groove is provided with a guide groove, and a guide block is slidably connected in the guide groove. One end of the guide block extends out of the guide groove and is fixedly connected to the limiting block. By setting the guide groove and the guide block, the movement of the limiting block is positioned to prevent the limiting block from completely leaving the groove.

[0011] Preferably, an auxiliary plate is fixedly connected to one side of the adjusting plate, and an auxiliary groove is provided on one side of the auxiliary plate. An arc-shaped block is fixedly connected to the inner wall of the auxiliary groove. With the setting of the auxiliary plate, the auxiliary groove and the arc-shaped block, the filter can be positioned during installation, so that it is not necessary to manually limit the filter during replacement, and ensure that the flange on the filter is aligned with the flange on the evaporator gas supply pipe and the flange installed on the compressor gas inlet pipe.

[0012] Preferably, handles are fixedly connected to both sides of the fixing plate, and the outer wall of the handle is provided with anti-slip texture. The handles facilitate the movement of the device by gripping them, and also facilitate the operation of the device, which is centrally positioned between the flange on the evaporator gas supply pipe and the flange installed on the compressor gas inlet pipe.

[0013] Preferably, the outer wall of the arc-shaped block is provided with a wear-resistant layer, and the inner wall of the auxiliary groove is provided with a wear-resistant layer. By providing a wear-resistant layer on the outer wall of the arc-shaped block, its wear resistance is improved and its service life is guaranteed. Similarly, by providing a wear-resistant layer on the inner wall of the auxiliary groove, its wear resistance is improved and its service life is guaranteed.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model provides a replacement device for an air source heat pump jet enthalpy-enhancing gas makeup filter. Through the adjustment mechanism, a transmission block on one of the two limiting plates is pushed. The transmission block drives a pressing block to move, bringing the sealing gasket and the center of the filter flange together. Releasing the transmission block, under the pressure of a first spring, causes the pressing block to return to its original position. One side of the transmission block re-engages with the filter flange, and the outer wall of the pressing block slides against the outer wall of the sealing gasket. The pressing block limits the sealing gasket on the filter flange, facilitating its connection with the flange on the filter. This allows for subsequent docking with the flanges on the evaporator's gas supply pipe and the compressor's inlet pipe. It allows for the simultaneous installation of two sealing gaskets, simplifies the operation, and improves replacement efficiency.

[0016] 2. This utility model provides a replacement device for an air source heat pump jet enthalpy-enhancing gas makeup filter. Through the setting of an auxiliary plate, an auxiliary groove, and an arc-shaped block, two adjusting plates are a set of flanges installed near the flanges on the evaporator gas supply pipe and the compressor inlet pipe. The inner wall of the auxiliary groove is fitted with the flange, that is, the flange part is embedded in the auxiliary groove. With the cooperation of the arc-shaped block, after the auxiliary plate is aligned with the flanges on the evaporator gas supply pipe and the compressor inlet pipe, it cannot move left or right. That is, the device is directly positioned on the flanges on the evaporator gas supply pipe and the compressor inlet pipe, so as to free up hands to install bolts and nuts.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides a replacement device for an air source heat pump jet enthalpy booster filter, including a rectangular fixing plate 1. Both sides of the fixing plate 1 are fixedly connected to handles 15. The outer wall of the handles 15 is provided with anti-slip texture. The device is moved by holding the handles 15 and is placed in the center between the flange on the evaporator gas pipe 101 and the flange installed on the compressor inlet pipe 102.

[0027] It should be noted that the filter 103 consists of a filter tube, which is filled with multiple layers of filter plates and fixed at both ends by welding flanges. The filter 103 is connected to the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102 through the two flanges respectively.

[0028] A circular sealing gasket 104 is provided between the flange on the evaporator gas supply pipe 101 of the filter 103 and the flange installed on the compressor inlet pipe 102. The flanges are provided with bolt holes, and the number of bolt holes is the same and they are evenly distributed so that the bolts pass through the through holes on the flanges. The nuts are tightened on the bolts to complete the connection between the filter 103 and the evaporator gas supply pipe 101 and the compressor inlet pipe 102.

[0029] A rectangular mounting groove 2 is provided on one side of the fixing plate 1 and extends through the fixing plate 1. A double-threaded rod 3 is rotatably connected to the inner wall of the mounting groove 2. One end of the double-threaded rod 3 extends through the fixing plate 1 and is fixedly connected to a knob. Both ends of the outer wall of the double-threaded rod 3 are threadedly connected to an adjusting plate 4. By rotating the double-threaded rod 3, the two adjusting plates 4 are controlled to move away from or closer to each other.

[0030] The adjusting plate 4 is provided with an adjusting mechanism 5. The adjusting mechanism 5 includes a limiting plate 51 fixedly connected to one side of the adjusting plate 4. A clamping groove is provided on one side of the limiting plate 51. The clamping groove fits against the outer wall of the filter 103 so as to limit the filter 103 between the two limiting plates 51 and move the filter 103 by moving the limiting plate 51.

[0031] A limiting groove 52 is provided on one side of the limiting plate 51. A guide rod 53 is fixedly connected to the inner wall of the limiting groove 52. The two ends of the guide rod 53 are respectively connected to the two opposite inner walls of the limiting groove 52 by welding. A transmission block 54 is slidably connected to the outer wall of the guide rod 53. A through hole adapted to the guide rod 53 is provided on one side of the transmission block 54. The transmission block 54 and the guide block 11 are slidably engaged.

[0032] A tapered pressing block 55 is fixedly connected to one side of the transmission block 54. One end of the transmission block 54 is fixedly connected to the inner wall of the limiting groove 52 through the first spring 56. The pressing block 55 can facilitate the limiting of the sealing gasket 104 after the sealing gasket 104 is attached to the flange on the filter 103.

[0033] Rectangular grooves 6 are provided on both sides of the limiting plate 51, but the two grooves 6 are not opposite to each other, so that the limiting block 7 has enough room to move. A cylindrical limiting block 7 is slidably connected in the groove 6. A guide groove 10 is provided on the inner side wall of the groove 6, with one end extending through the limiting plate 51. A rectangular guide block 11 is slidably connected in the guide groove 10. One end of the guide block 11 extends out of the guide groove 10 and is fixedly connected to the limiting block 7. The movement of the limiting block 7 is positioned by the guide groove 10 and the guide block 11 to prevent the limiting block 7 from completely disengaging from the groove 6.

[0034] A rectangular actuating block 9 is fixedly connected to one side of the outer wall of the limiting block 7. The outer wall of the limiting block 7 is provided with a wear-resistant layer to improve the wear resistance of the limiting block 7 and increase its service life. One end of the limiting block 7 is elastically connected to the inner side wall of the groove 6 through the second spring 8, and the other end of the limiting block 7 extends out of the groove 6.

[0035] Based on the above structure, the present invention includes the following implementation process:

[0036] When replacing filter 103, rotate the bolts on the flange on the evaporator gas pipe 101 and the flange on the compressor inlet pipe 102, remove the bolts, release the gasket 104 between filter 103 and the two flanges, remove the gasket 104 and the old filter 103, push the limiting block 7 to retract the part of the limiting block 7 that is outside into the groove 6 to avoid movement interference with the flange of filter 103, and place the new filter 103 in the center between the two limiting plates 51;

[0037] Rotating the knob drives the double-headed threaded rod 3 to bring the two adjusting plates 4 closer together. The two adjusting plates 4 then bring the two limiting plates 51 closer together, so that the limiting plates 51 are close to the filter 103 and the inner wall of the clamping groove is in contact with the outer wall of the filter 103. The clamping groove is clamped and positioned by the two limiting plates 51, and the filter 103 is fixed at this time.

[0038] Push the transmission block 54 on one of the two limiting plates 51. The transmission block 54 drives the pressing block 55 to move. The transmission block 54 applies pressure to the first spring 56, causing one side of the transmission block 54 to disengage from the flange of the filter 103, and placing the sealing gasket 104 and the center of the flange of the filter 103 together, so that the bolt hole on the sealing gasket 104 is aligned with the through hole on the flange of the filter 103.

[0039] At this time, one end of the limiting block 7 passes through the bolt hole on the flange of the filter 103 and is inserted into the bolt hole of the sealing gasket 104, so that the sealing gasket 104 will not rotate after being limited by the pressing block 55. This is to prevent the adjusted sealing gasket 104 from rotating on its own when the new filter 103 is moved due to vibration or when the flange of the filter 103 is connected to the flange on the evaporator gas pipe 101 and the flange installed on the compressor gas inlet pipe 102. In this case, the sealing gasket 104 needs to be manually rotated again so that the bolt holes can be aligned.

[0040] At this time, the transmission block 54 can be released. Under the pressure of the first spring 56, the transmission block 54 drives the pressing block 55 to move back and reset. One side of the transmission block 54 re-contacts the flange of the filter 103, and the outer wall of the pressing block 55 slides against the outer wall of the sealing gasket 104. The pressing block 55 limits the sealing gasket 104 on the flange of the filter 103.

[0041] At this point, the limit plate 51 can be moved to move the filter 103 to be placed in the center between the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102, so that the flanges at both ends of the filter 103 are respectively attached to and aligned with the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102, so that the bolt holes on the flange of the filter 103 are aligned with the bolt holes on the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102.

[0042] The groove 6, the second spring 8, and the limiting block 7 facilitate hole positioning of the sealing gasket 104, which is limited to the flange on the filter 103. This eliminates the need to adjust the angle of the sealing gasket 104 during subsequent installation, further improving replacement efficiency.

[0043] Please see Figures 1-4 This utility model provides a replacement device for the jet enthalpy booster filter of an air source heat pump:

[0044] A rectangular auxiliary plate 12 is symmetrically fixedly connected to one side of the adjusting plate 4. A semi-circular auxiliary groove 13 is opened on one side of the auxiliary plate 12. The inner wall of the auxiliary groove 13 is provided with a wear-resistant layer to improve its wear resistance and ensure the service life of the auxiliary plate 12. The auxiliary groove 13 should only be two-thirds the width of the flange installed on the evaporator gas pipe 101 and the flange installed on the compressor gas inlet pipe 102 to avoid movement interference with the pressing block 55.

[0045] An arc-shaped block 14 is fixedly connected to the inner wall of the auxiliary groove 13. The outer wall of the arc-shaped block 14 is provided with a wear-resistant layer to improve its wear resistance and ensure its service life.

[0046] Based on the above structure, the present invention includes the following implementation process:

[0047] Rotating the double-headed threaded rod 3 causes the two adjusting plates 4 to drive the two auxiliary plates 12 closer to each other, so that the two adjusting plates 4 are a set close to the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102, and the inner wall of the auxiliary groove 13 fits with the flange, that is, the flange part is embedded in the auxiliary groove 13. With the cooperation of the arc block 14, the auxiliary plate 12 can no longer move left or right after it is aligned with the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102. That is, the device is directly positioned on the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102, so as to free up hands to install bolts and nuts.

[0048] The filter 103 can be positioned during installation by setting the auxiliary plate 12, auxiliary groove 13 and arc block 14, eliminating the need to manually limit the filter 103 during replacement, and ensuring that the flange on the filter 103 is aligned with the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102.

[0049] Pass one end of the bolt through the bolt hole of the flange on the evaporator gas supply pipe 101 or the bolt hole of the flange on the compressor inlet pipe 102, then through the bolt on the sealing gasket 104, and finally through the bolt hole on the flange of the filter 103. Tighten the nut on the bolt to complete the connection between the flange of the filter 103 and the flange on the evaporator gas supply pipe 101 and the flange on the compressor inlet pipe 102, thereby completing the replacement of the filter 103.

[0050] During this process, the semi-circular pressing block 55 will contact the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102 and be squeezed by the flange, so that the pressing block 55 is pressed and moves away from the contact with the sealing gasket 104. Thus, the sealing gasket 104 can be installed between the flange of the filter 103 and the flange on the evaporator gas supply pipe 101 and the flange installed on the compressor inlet pipe 102 while the filter 103 is being installed.

[0051] By adjusting the setting of the mechanism 5, the sealing gasket 104 can be easily positioned together with the flange on the filter 103, so as to facilitate subsequent docking with the flange on the evaporator gas pipe 101 and the flange installed on the compressor inlet pipe 102, simplifying the operation steps and improving the replacement efficiency.

[0052] Based on the above structure:

[0053] After the filter 103 is replaced, one end of the limiting block 7 has been squeezed out of the corresponding bolt hole by the bolt. Therefore, the double-threaded rod 3 can be reversed directly, so that the two adjusting plates 4 drive the two limiting plates 51 away from each other until they move to the maximum distance, that is, both adjusting plates 4 are in contact with the inner side wall of the mounting groove 32. At this time, the limiting plate 51 is completely detached from the filter 101, and the auxiliary plate 12 is detached from and away from the flange on the evaporator gas pipe 101 and the compressor inlet pipe 102. The device can then be removed and properly placed so that the above operation can be repeated when the filter 103 needs to be replaced next time.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
