Description

Technical Field

[0001] This utility model relates to the field of chiller units, specifically to a vibration-damping and noise-reducing scroll chiller unit. Background Technology

[0002] Scroll chillers are a type of mechanical equipment used in refrigeration or air conditioning systems. They typically employ scroll compressors to achieve the refrigeration effect. These units utilize the internal rotation of the compressor to draw in low-temperature, low-pressure steam or gas, compressing it into high-temperature, high-pressure gas, thus completing the refrigeration cycle.

[0003] Existing scroll chiller units, patent number CN221744347U discloses a low-noise scroll chiller unit. Through a damping and vibration-damping component, the deformation force of the damping spring is used to convert downward kinetic energy into potential energy to reduce kinetic energy, thereby effectively controlling the noise generated by the vibration amplitude of the low-noise scroll chiller unit body during operation. The installation of casters and grounding fixing components facilitates the movement and installation of the chiller unit. However, the chiller unit generates not only longitudinal vibration but also lateral vibration during use. The damping spring absorbs more longitudinal vibration but less lateral vibration, which also generates a lot of noise, causing noise pollution. At the same time, the casters are fixed to the bottom of the fixing frame, which is inconvenient to disassemble and will affect the grounding fixing component's contact with the ground, making installation inconvenient. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vibration-damping and noise-reducing scroll chiller unit to achieve horizontal and vertical vibration reduction and effectively control the noise generated by vibration when the scroll chiller unit is working.

[0005] The purpose of this utility model is achieved through the following technical solution: This vibration-damping and noise-reducing vortex chiller unit includes:

[0006] The base has a square frame structure;

[0007] A buffer mounting frame includes a frame body and a buffer assembly movably mounted on the frame body. The frame body is slidably mounted in a base in three directions (horizontal, vertical, and vertical) via the buffer assembly.

[0008] The generator unit itself is fixedly mounted on the frame;

[0009] A movable component, detachably mounted on the outside of the base, is used to move the entire base; and

[0010] The outer shielding box is installed outside the unit body and fixed to the top of the base.

[0011] As a further technical solution, the buffer assembly includes a horizontal vertical buffer assembly installed on the frame in a horizontal or vertical direction and a vertical buffer assembly installed on the frame in a vertical direction.

[0012] As a further technical solution, mounting holes are opened on the side wall of the frame at the corresponding positions of each horizontal and vertical buffer component, and limiting grooves are opened on the inner wall of the base at the corresponding positions of each horizontal and vertical buffer component, so that the horizontal and vertical buffer components are slidably installed between the mounting holes and the limiting grooves.

[0013] As a further technical solution, the horizontal and vertical buffer assembly includes a damping sleeve A that is slidably installed along the mounting hole. The damping sleeve A is slidably sleeved on one end of the slide rod by a buffer spring A. The other end of the slide rod is fixedly connected to a locking plate, which is used to relatively slide into the corresponding limiting groove.

[0014] As a further technical solution, the vertical buffer assembly includes several fixed seats fixed to the bottom of the inner side of the base. A damping sleeve B is slidably sleeved on the fixed seat through a buffer spring B, and the top of the damping sleeve B contacts the bottom of the frame.

[0015] As a further technical solution, the moving component includes a slotted block mounted on the base, with a swivel caster wheel fixedly mounted on the bottom of the block.

[0016] As a further technical solution, a slot is provided on the base corresponding to each moving component. The slot is "T" shaped and fits the card block.

[0017] As a further technical solution, a fixing hole is opened on the base above each card slot, and a side mounting plate is provided on the outside of the card block. After the card block and the card slot are assembled, the side mounting plate is connected and fixed to the fixing hole by hand-tightening bolts.

[0018] As a further technical solution, several fixing blocks are provided on the outer wall of the base, and several fixing bolts are installed on each fixing block.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. During use, the vibration generated by the main body of the vortex chiller is transmitted to the frame, and then to the damping sleeve B and damping sleeve A. The damping sleeve B contracts and deforms, and the buffer spring B is squeezed to absorb the longitudinal vibration. The sliding block is pushed along the mounting groove by the clamping plate to squeeze the damping sleeve A and the buffer spring A to absorb the lateral vibration, thereby reducing the noise generated by the vibration of the main body of the vortex chiller during operation.

[0021] 2. By removing the hand-tightening bolts located in the fixing holes, and then pulling the locking block out along the slot, the casters located at the bottom of the base can be removed. This allows for easy movement of the base using the casters, and also avoids obstructing the installation and fixing of the base, thus improving flexibility. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings:

[0029] Example: As attached Figures 1-5 As shown, this vibration-damping and noise-reducing vortex chiller unit includes a base 1, a limiting slide groove 11, a fixing hole 12, a slot 13, a unit body 2, a buffer mounting bracket 3, a frame 31, a mounting hole 32, a damping sleeve A33, a slide rod 34, a clamping plate 35, a buffer spring A36, a fixing seat 37, a damping sleeve B38, a buffer spring B39, a moving component 4, a clamping block 41, a side mounting plate 42, a hand-tightening bolt 43, a moving caster wheel 44, a fixing block 5, a fixing bolt 6, and an outer shielding box 7.

[0030] Reference Appendix Figure 1 , 2 The base 1, a square frame structure, is located at the bottom of the entire vibration-damping and noise-reducing scroll chiller unit. For example... Figure 2 , 3As shown, the buffer mounting bracket 3 includes a frame 31 and a buffer assembly movably mounted on the frame 31. The frame 31 is slidably mounted within the base 1 in three directions (horizontal, vertical, and sloping) via the buffer assembly. Further, the buffer assembly includes a horizontal-vertical buffer assembly mounted on the frame 31 in a horizontal or vertical direction, and a vertical buffer assembly mounted on the frame 31 in a vertical direction. Figure 4 As shown, a mounting hole 32 is opened on the side wall of the frame 31 at a position corresponding to each horizontal and vertical buffer component, and a limiting groove 11 is opened on the inner wall of the base 1 at a position corresponding to each horizontal and vertical buffer component, so that the horizontal and vertical buffer components can be slidably installed between the mounting hole 32 and the limiting groove 11.

[0031] Furthermore, the horizontal and vertical buffer assembly includes a damping sleeve A33 slidably mounted along the mounting hole 32, the damping sleeve A33 being slidably sleeved on one end of the slide rod 34 via a buffer spring A36. Figure 4 The inner end of the middle section), the other end of the slide bar 34 ( Figure 4 The inner and outer ends are fixedly connected to the card plate 35, and the card plate 35 can slide relative to the corresponding limiting groove 11. Preferably, the size of the limiting groove 11 is larger than that of the card plate 35. Because the size of the limiting groove 11 is larger than that of the card plate 35, when the frame 31 vibrates, the card plate 35 can move in multiple directions (horizontal, vertical, and vertical) within the limiting groove 11 to avoid obstructing the vibration of the frame 31.

[0032] Furthermore, the vertical buffer assembly includes several fixed seats 37 fixed to the bottom inner side of the base 1. A damping sleeve B38 is slidably sleeved on the fixed seat 37 through a buffer spring B39, and the top of the damping sleeve B38 contacts the bottom of the frame 31.

[0033] like Figure 2 As shown, the unit body 2 is fixedly installed (placed) on the frame 31.

[0034] like Figure 3 , 5 As shown, the movable component 4 is detachably installed on the outside of the base 1 (preferably, the movable component 4 is located at the four corners of the base 1), which can drive the base 1 to move as a whole. Preferably, an outer shielding box 7 is provided on the outside of the unit body 2, and the outer shielding box 7 is fixed to the top of the base 1, which can further control the noise generated by vibration.

[0035] Furthermore, such as Figure 5As shown, the movable component 4 includes a locking block 41 mounted on the base 1 in a slotted manner, with a caster wheel 44 fixedly mounted on the bottom of the locking block 41. A slot 13 is provided on the base 1 at a position corresponding to each movable component 4. The slot 13 is T-shaped and fits the locking block 41 to ensure stable engagement. A fixing hole 12 is provided on the base 1 above each slot 13. A side mounting plate 42 is provided on the outer side of the locking block 41. After the locking block 41 is assembled with the slot 13, the side mounting plate 42 is connected and fixed to the fixing hole 12 by a hand-tightening bolt 43, ensuring stable fixation while facilitating disassembly.

[0036] Reference Appendix Figure 1 , 2 3. Several fixing blocks 5 (preferably one on each side) are provided on the outer wall of the base 1, and several fixing bolts 6 are installed on each fixing block 5.

[0037] The working process of this utility model:

[0038] After moving the vortex chiller unit body 2 (the entire base 1) to the installation position by rolling the casters 44 on the ground, lift the base 1, then remove the hand-tightening bolts 43 located in the fixing holes 12, and then remove the casters 44 located at the bottom of the base 1 by pulling out the locking block 41 along the locking groove 13. Then lower the base 1 to the ground, and then use the fixing bolts 6 to pass through the fixing block 5 and install the fixing bolts 6 in the corresponding holes in the ground to fix the base 1. During operation, the vibration generated by the main body 2 of the scroll chiller is transmitted to the frame 31, and then through the frame 31 to the damping sleeves B38 and A33 (i.e., the horizontal and vertical buffer components and the vertical buffer component) located at the bottom and side of the frame 31, respectively. The damping sleeve B38 undergoes contraction deformation, which, together with the buffer spring B39, provides buffering to absorb longitudinal vibration. At the same time, the sliding rod 34 is pushed to slide along the mounting hole 32 by the locking plate 35 in the limiting slide groove 11, which compresses the damping sleeve A33 and the buffer spring A36 to absorb lateral vibration. Finally, the outer shielding box 7 is installed on the outside of the main body 2 of the scroll chiller to reduce the noise generated by the main body 2 of the scroll chiller during operation.

[0039] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
