Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an external filter device. Background Art

[0002] The chiller filter is an important component used to filter impurities and dirt in the chiller circulation system. During the use of the chiller, due to the corrosion and wear of pipes, water pumps, valves and other equipment, a large amount of impurities and dirt will be generated in the water. If these impurities and dirt are not cleaned in time, they will form scale, resulting in the performance of the chiller. It will also pose a threat to the safety of the equipment. Therefore, the main function of the filter component is to collect these solid impurities to prevent them from clogging the system and capillaries or expansion valves, and ensure that the chiller's piping system is unobstructed.

[0003] In the existing chiller system, the design and installation of external filter devices occupy a pivotal position. However, careful observation will reveal that these filter devices often adopt a relatively fixed installation method, such as being firmly fixed on the wall or on a heavy wooden board. Although this installation mode ensures the stability and reliability of the filter device to a certain extent, there are also some limitations that cannot be ignored. Specifically, the fixed installation method requires the filter device to be connected to the chiller through a longer pipeline. These lengthy pipelines not only make the installation and maintenance process more complicated, but also take up a lot of space, making the layout of the entire system appear less compact and efficient. What is more difficult is that when the chiller needs to be transported or moved, these long pipelines and fixed filter devices become a major problem. They not only increase the difficulty of transportation, but also may cause the risk of system performance damage due to the bending or stretching of the pipeline during transportation. In addition, this installation method also brings inconvenience to the replacement of the filter element. Since the filter device is fixed in a relatively fixed position, it is necessary to dismantle the pipeline or move the entire filter device when replacing the filter element, which undoubtedly increases the complexity and difficulty of the operation.

The water pump 8 is connected to the filter assembly 6, and the filter assembly 6 and the water pump 8 are connected to the outside of the chiller 1 through the substrate 4 and the connecting member.

[0046] First, the connecting member is directly arranged on the surface of the chiller 1. This connecting member not only ensures a firm connection between the external filter device and the chiller 1, but also provides a foundation for the installation of subsequent components. Next, the substrate 4 is connected to the surface of the connecting member and is arranged perpendicular to the surface of the chiller 1. This vertical design helps to optimize space utilization and ensure that the filter assembly 6 can be smoothly installed and operated. On the surface of the substrate 4, placement holes 5 are processed that run through the entire substrate. These placement holes 5 are used to place the filter assembly 6. The filter assembly 6 can be easily removed for cleaning or replacement when needed. The filter assembly 6 can effectively remove impurities and sediments in the cooling water to ensure the quality of the cooling water entering the chiller 1. The surface of the substrate 4 is also provided with A fastener 7 is provided, which can not only firmly fix the water pump 8 on the base plate 4 to prevent the water pump 8 from shaking during operation, but also a water pump 8 is provided on the base plate 4, which is the power source of the external filter device. It is worth noting that the water pump 8 and the filter assembly 6 are interconnected, ensuring that the cooling water can be filtered smoothly. At the same time, the filter assembly 6 and the water pump 8 are connected to the outside of the chiller 1 through the base plate 4 and the connecting member, which not only ensures the filtering effect, but also does not affect the normal operation of the chiller 1. In summary, this external filter device achieves efficient filtration and cleaning of cooling water through the coordinated work of its unique connecting member, base plate 4, placement hole 5, filter assembly 6, fastener 7 and water pump 8.

[0047] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 3 As shown; the connecting member is a fixed connecting structure 2, wherein the fixed connecting structure 2 includes:

[0048] The bottom plate 21 is disposed at the bottom of the chiller 1 and is in contact with the bottom surface of the chiller 1;

[0049] The telescopic rod 22 is fixedly mounted on the outer side of the bottom plate 21 and is perpendicular to the bottom plate 21;

[0050] A top fixing member 23 is fixedly mounted on the telescopic end of the telescopic rod 22;

[0051] A stopper 24 is disposed on the top fixing member 23 and is used to make the telescopic rod 22 close to the surface of the chiller 1; and

[0052] There are two clamps 25, which are arranged on the outside of the telescopic rod 22, wherein the telescopic rod 22 is connected to the mounting plate 26 through the clamp 25, and the mounting plate 26 is welded to the base plate 4. In order to stably and firmly install the external filter device on the chiller 1, a fixed connection structure 2 is adopted, which mainly includes a bottom plate 21, a telescopic rod 22, a top fixing member 23, a limit member 24, a clamp 25 and a mounting plate 26. First, the bottom plate 21 is placed at the bottom of the chiller 1 to ensure that it is in close contact with the bottom surface of the chiller 1. In this way, the bottom plate 21 provides a stable supporting foundation for the entire connection structure. Then, the telescopic rod 22 is fixedly installed on the outside of the bottom plate 21 and is arranged perpendicular to the bottom plate 21. The telescopic function of the telescopic rod 22 allows adjustment according to the actual size and shape of the chiller 1 to ensure that the connection structure can adapt to various types of chillers. A top fixing part 23 is fixedly installed on the telescopic end of the telescopic rod 22. The function of the top fixing part 23 is to ensure that the telescopic rod 22 can fit tightly on the surface of the chiller 1, thereby providing stable support. In order to further enhance the stability of the connection, a limiter 24 is set on the top fixing part 23. The limiter 24 can ensure that the telescopic rod 22 remains fixed after being adjusted to a suitable position to prevent it from loosening or displacement during use. The telescopic rod 22 is connected to the mounting plate 26 through a clamp 25, and the mounting plate 26 is welded to the base plate 4. In this way, the entire external filter device is firmly installed on the chiller 1, ready for filtering cooling water. Through this fixed connection structure 2, not only the stability and safety of the external filter device can be ensured, but also it can be conveniently adjusted and installed according to the actual situation of the chiller 1, which provides a strong guarantee for the operation of the cooling water system.

[0053] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 3As shown; the limiting member 24 includes:

[0054] An upper connecting piece 241, one end of which is fixedly mounted on the top fixing piece 23, and the upper connecting piece 241 and the top fixing piece 23 are arranged perpendicular to each other;

[0055] The lower connecting piece 242 is disposed on the lower side of the upper connecting piece 241 and contacts one side surface of the upper connecting piece 241. The end of the lower connecting piece 242 away from the telescopic rod 22 is provided with a hook portion 243, and the hook portion 243 is placed at the top corner of the chiller 1.

[0056] A limiting screw 244, one end of which is fixedly mounted on the surface of the lower connecting piece 242, and the other end of which penetrates and extends to the top of the upper connecting piece 241; and

[0057] The limiting hand-tightening nut 245 is threadedly connected to the outer side of the limiting screw 244, and one side surface of the limiting nut 245 contacts the upper connecting piece 241. The working principle of the limiting member 24 is further elaborated in detail to ensure that the external filter device can be firmly installed on the chiller 1. First, the limiting member 24 is composed of multiple parts, including an upper connecting piece 241, a lower connecting piece 242, a hook portion 243, a limiting screw 244 and a limiting hand-tightening nut 245. One end of the upper connecting piece 241 is fixedly installed on the top fixing piece 23, and is perpendicular to the top fixing piece 23. This design enables the upper connecting piece 241 to stably support the subsequent limiting structure, and at the same time, is tightly combined with the top fixing piece 23 to form a stable connection point. The lower connecting piece 242 is arranged on the lower side of the upper connecting piece 241, and contacts with one side surface of the upper connecting piece 241. The end of the lower connecting piece 242 away from the telescopic rod 22 is provided with a hook portion 243. This hook portion 243 is specially designed to be placed at the top corner of the chiller 1. By directly contacting the chiller 1, the stability of the entire connection structure is increased. The limiting screw 244 One end is fixedly mounted on the surface of the lower connecting piece 242, and the other end penetrates and extends to the top of the upper connecting piece 241. By adjusting the position of the limiting screw 244, we can adjust the distance between the upper connecting piece 241 and the lower connecting piece 242, thereby ensuring that the hook portion 243 can fit tightly at the top corner of the chiller 1. Finally, the limiting hand-tightening nut 245 is threadedly connected to the outer side of the limiting screw 244. By rotating the limiting hand-tightening nut 245, we can adjust the contact tightness between it and the upper connecting piece 241, thereby achieving the entire limiting member 2 4 is fastened and locked. When the limiting hand-tightening nut 245 is tightened, it will firmly press the upper connecting piece 241 and the lower connecting piece 242 together to ensure that the hook portion 243 can be stably fixed at the top corner of the chiller 1. Through this design, the limiting member 24 can effectively enhance the connection stability between the external filter device and the chiller 1. Even under the influence of the external environment, such as vibration or wind, the limiting member 24 can ensure that the external filter device is always firmly installed on the chiller 1, thereby ensuring the normal operation of the entire cooling water system.

[0058] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 3As shown; a connecting hole for the displacement of the limiting screw 244 is processed on the surface of the upper connecting piece 241, and the limiting screw 244 is placed on the inner side of the connecting hole. The connecting hole is in the shape of an elongated strip as a whole, and is arranged parallel to the length direction of the upper connecting piece 241. In the external filter device, the limiting member 24 is a key component to ensure that the entire device is firmly installed on the chiller 1, wherein the upper connecting piece 241, as an important part of the limiting member 24, is arranged vertically with the top fixing member 23, and plays the role of supporting and fixing the lower connecting piece 242. It is particularly pointed out that a connecting hole for the displacement of the limiting screw 244 is processed on the surface of the upper connecting piece 241. The design of this connecting hole allows the limiting screw 244 to move freely in the hole, thereby adjusting the distance between the lower connecting piece 242 and the chiller 1. Specifically, the connecting hole is in the shape of an elongated strip as a whole, with a certain length and width, allowing the limiting screw 244 to move horizontally in the hole. At the same time, the length direction of the connecting hole is parallel to the upper connecting piece The length directions of the connecting pieces 241 are arranged parallel to each other. Such a design makes the limiting screw 244 more stable when moving, and there will be no shaking or deviation. In actual application, when it is necessary to adjust the tightness between the external filter device and the chiller 1, the limiting screw 244 can be pushed to move in the connecting hole by rotating the limiting hand nut 245. As the limiting screw 244 moves, the lower connecting piece 242 and the hook portion 243 thereon will also move accordingly, thereby achieving a tighter or looser fixation of the top corner of the chiller 1. This long strip-shaped connecting hole design not only enhances the flexibility and adaptability of the limiting piece 24, but also makes the entire external filter device more convenient and quick during installation and adjustment. No matter what degree of concave-convex or unevenness exists at the top corner of the chiller 1, the position of the limiting screw 244 in the connecting hole can be adjusted to achieve a stable fixation, thereby ensuring that the external filter device can operate stably for a long time.

[0059] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 3As shown; the mounting plate 26 and the base plate 4 are arranged perpendicular to each other, and a reinforcing plate 9 is fixedly installed between the mounting plate 26 and the base plate 4. The cross section of the reinforcing plate 9 is arranged in a right-angled triangle. The mounting plate 26 and the base plate 4 are arranged perpendicular to each other. This vertical arrangement not only optimizes the spatial layout, making the entire filter device more compact, but also provides conditions for the introduction of the reinforcing plate 9. Then, the reinforcing plate 9 is fixedly installed between the mounting plate 26 and the base plate 4. The cross section of the reinforcing plate 9 is arranged in a right-angled triangle. This shape design enables the reinforcing plate 9 to fit tightly with the mounting plate 26 and the base plate 4 at the same time, thereby providing stronger support and Fixing effect, the two right-angled sides of the right-angled triangle reinforcement plate 9 are in contact with the surface of the mounting plate 26 and the base plate 4 respectively, and are firmly connected together by welding, bolt connection or other appropriate fixing methods. This connection method ensures that the reinforcement plate 9 can effectively connect the mounting plate 26 and the base plate 4 into a whole, and enhances the connection strength between them. When the external filter device is subjected to external forces such as vibration and impact during operation, the reinforcement plate 9 can bear part of the load and disperse it to the mounting plate 26 and the base plate 4, thereby reducing the stress concentration of these components and improving the stability and reliability of the entire device.

[0060] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 3 As shown; the filter assembly 6 comprises:

[0061] The base 61 is placed on the surface of the substrate 4, and its overall size is larger than the inner diameter of the placement hole 5, wherein the surface of the base 61 is also connected with an interface 62;

[0062] The filter 63 is detachably connected to the base 61. The filter 63 is located on the inner side of the placement hole 5. The base 61 is placed on the surface of the substrate 4. Its overall size is larger than the inner diameter of the placement hole 5. This design ensures that the base 61 can be firmly placed on the substrate 4 and will not be easily moved or fallen off due to water flow or other external forces. There is also an interface 62 on the surface of the base 61. This interface 62 is used to connect to the water pump 8 or other piping systems to achieve the inflow and outflow of cooling water. Next, the filter 63 is designed to be detachably connected to the base 61 and is located on the inner side of the placement hole 5. This design allows the filter 63 to be easily installed and disassembled, which is convenient for users to clean, replace or repair. The filter 63 itself has a filtering function and can remove impurities and sediments in the cooling water. When cooling water flows in from the water pump 8 or other piping system, it will first pass through the filter 63, and then the filtered clean water will flow out through the interface 62 of the base 61, and finally return to the chiller 1. During the entire filtering process, the base 61 plays a supporting and connecting role, ensuring that the filter 63 can be stably placed in the placement hole 5 and effectively connected to the water pump 8 or other piping system, and the filter 63 is the core component for realizing the filtering function. It can effectively remove impurities and sediments in the cooling water to ensure the cleanliness of the cooling water. The filter 63 is a prior art, and it is fixed to the base 61 by a threaded connection, wherein the water source flows into the inner side of the filter 63 through the interface 62, and is filtered and impurities are removed by the filter 63. When cleaning, it is convenient to separate the base 61 from the filter 63.

[0063] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 3As shown; a hose 10 is connected to the water outlet end of the water pump 8, and the other end of the hose 10 is arranged on the outside of the interface 62, wherein the water pump 8 is connected to the filter 63 through the hose 10. In the external filter device, the water pump 8 serves as a power source and is responsible for driving the cooling water to circulate in the system. A hose 10 is connected to the water outlet end of the water pump 8, and this hose 10 serves as a bridge connecting the water pump 8 and the interface 62 in the filter assembly 6. Specifically, the other end of the hose 10 is arranged on the outside of the interface 62. The interface 62 is located on the base 61 of the filter assembly 6 and is the entrance for the cooling water to flow into the filter. When the water pump 8 is started, it will extract the cooling water in the chiller 1 Water is transported to the hose 10 through its water outlet. The hose 10 has good flexibility and sealing performance. It can bend or stretch as the system runs to ensure a stable connection between the water pump 8 and the interface 62. At the same time, the hose 10 can also effectively prevent leakage of cooling water during transmission to ensure the safe operation of the system. When the cooling water flows into the interface 62 through the hose 10, it will further enter the filter 63 in the filter assembly 6. The filter 63 is responsible for filtering the cooling water to remove impurities and sediments therein. The filtered clean water flows out through other outlets of the base 61 and finally returns to the chiller 1 to complete the entire circulation process.

[0064] The specific working principle of the external filter device of the utility model is as follows:

[0065] The external filter device is mainly composed of a chiller 1, a connecting member, a base plate 4, a filter assembly 6, a water pump 8 and other components. The device is fixed to the outside of the chiller 1 through the connecting member to achieve external installation.

[0066] First, the connecting component adopts a fixed connecting structure 2, the bottom plate 21 is in close contact with the bottom surface of the chiller 1 to provide stable support, the telescopic rod 22 is connected to the mounting plate 26 through the clamp 25, and the mounting plate 26 is welded to the base plate 4 to form a stable mounting frame, and a limiting member 24 is provided on the top fixing member 23, the upper connecting piece 241 is connected to the lower connecting piece 242 through a limiting screw 244 and a limiting hand-tightening nut 245, and the hook portion 243 of the lower connecting piece 242 is placed at the top corner of the chiller 1, and by adjusting the position of the limiting screw 244 in the long strip connecting hole of the upper connecting piece 241, the fit between the lower connecting piece 242 and the chiller 1 can be flexibly adjusted to ensure that the entire device is firmly fixed on the chiller 1, and can be easily expanded or adjusted according to actual needs, and different types can be replaced. The filter assembly 6 can adapt to different filtering needs. In addition, it can also be compatible with different types of chillers 1, has good versatility, and improves the flexibility of the entire external filter device. At the same time, the base plate 4 and the mounting plate 26 are arranged perpendicular to each other, and a reinforcing plate 9 is installed therebetween. The cross-section of the reinforcing plate 9 is arranged in a right-angled triangle, which increases the connection strength between the base plate 4 and the mounting plate 26, making the entire device more stable. A placement hole 5 is processed on the surface of the base plate 4, and the filter assembly 6 is placed in the placement hole 5. The base 61 is placed on the surface of the base plate 4, and its overall size is larger than the inner diameter of the placement hole 5 to ensure stable placement. The base 61 is connected with an interface 62 for connecting the water pump 8 and the filter 63. The filter 63 is detachably connected to the base 61 and is located on the inner side of the placement hole 5, which is convenient for cleaning and replacement.

[0067] In summary, the external filter device is firmly installed on the outside of the chiller 1 through a connecting component, and the filter component can be cleaned and replaced without affecting the operation of the chiller 1. The maintenance personnel only need to perform simple operations to remove the filter component from the placement hole 5, perform necessary cleaning or replacement, and then put it back. This design greatly improves the convenience and efficiency of maintenance. The cooling water is driven to circulate through the water pump 8 and is filtered by the filter component 6 to ensure the cleanliness of the cooling water, thereby providing a strong guarantee for the stable operation of the cooling water system.

[0068] By using the telescopic rod 22, the top fixing part 23, the limiting part 24 and the clamp 25 in coordination, the external filter device is tightly connected to the chiller 1. The connection is firm and reliable and can withstand large external forces. The fixed connection structure 2 ensures that the position of the external filter device on the chiller 1 is fixed, reducing the risk of displacement caused by vibration or external force and improving the stability of the system. The design of the telescopic rod 22 allows the height and angle of the external filter device to be adjusted within a certain range to adapt to different installation environments and requirements. The limiting part 24, through the upper connecting plate 241, the lower connecting plate 242, the limiting screw 244 and the limiting hand-tightening nut 245, closes the telescopic rod 22 to the surface of the chiller 1, increasing the safety and stability of the connection. It can also be adjusted according to the size of the chiller 1 and is suitable for chillers 1 of various models and specifications.

[0069] Embodiment 2: Combination Figure 4 and Figure 5 As shown, the difference from the first embodiment is that the connecting member is a suspension type connecting structure 3, wherein the suspension type connecting structure 3 includes:

[0070] A connecting plate 31 is disposed on the outside of the chiller 1, one side of which is in contact with the surface of the chiller 1, two connecting holes 32 are processed on the surface of the connecting plate 31, and the connecting plate 31 and the base plate 4 are welded together; and

[0071] The limiting nails 33 are fixedly installed on the outside of the chiller 1, and their distribution position and number are adapted to the connecting holes 32. The connecting plate 31 is suspended to the outside of the limiting nails 33 through the connecting holes 32. If the connecting component is designed as a hanging connecting structure 3, then the installation and working principle of the entire external filter device will change. The hanging connecting structure 3 is a connection method for fixing the external filter device on the outside of the chiller 1. The structure is mainly composed of a connecting plate 31, a connecting hole 32 and a limiting nail 33. The connecting plate 31 is arranged on the outside of the chiller 1, and one side surface is in close contact with the surface of the chiller 1 to ensure a stable connection. Two connecting holes 32 are processed on the surface of the connecting plate 31. The positions and sizes of the two connecting holes 32 are determined according to the positions and diameters of the limiting nails 33 pre-installed on the chiller 1. The limiting nails 33 are fixedly installed It is installed on the outside of the chiller 1, and its distribution position and number are compatible with the connecting holes 32 on the connecting plate 31. During installation, the connecting plate 31 is placed on the outside of the chiller 1, and the connecting holes 32 are aligned with the limiting nails 33. Then the connecting plate 31 is hung to the outside of the limiting nails 33 through the connecting holes 32. This hanging design enables the connecting plate 31 to be stably fixed on the chiller 1 without the need for additional fasteners or screws. After the connecting plate 31 is fixed, the filter assembly 6 and the water pump 8 are installed on the base plate 4. This design not only simplifies the installation process, but also improves the structural stability of the entire external filter device. In summary, the hanging connection structure 3 realizes the stable installation of the external filter device on the outside of the chiller 1 through the cooperation of the connecting plate 31 and the limiting nails 33. This design not only simplifies the installation process, but also improves the structural stability and working efficiency of the entire device.

[0072] At the same time, a limit pin 33 is provided with a T-shaped cross section, and the connecting hole 32 includes a large hole and a small hole, wherein two large holes and two small holes are processed on the surface of the connecting plate 31, wherein the large hole and the small hole are connected to each other, and the inner diameter of the large hole is adapted to the end face diameter of the limit pin 33, and the inner diameter of the small hole is smaller than the end face diameter of the limit pin 33. The limit pin 33 and the connecting hole 32 of the hanging connection structure 3 are described in detail. In the external filter device, in order to ensure that the connecting plate 31 can be firmly suspended on the outside of the chiller 1, a cross section is adopted. The T-shaped limit pin 33 is structurally divided into two parts: a larger end face part and a smaller rod-shaped part. This design allows the connecting plate 31 to be fixed on the limit pin 33 through a specific connection method, while ensuring the stability and reliability of the connection. In order to achieve the adaptation with the T-shaped limit pin 33, two holes of different sizes are processed on the surface of the connecting plate 31: a large hole and a small hole. The large hole and the small hole are interconnected to form a special connecting hole 32 structure. The inner diameter of the large hole is equal to the end face diameter of the limit pin 33. This means that when the end face of the limiting nail 33 is inserted into the large hole, the two can fit tightly to ensure that the connecting plate 31 does not move in the horizontal direction. At the same time, the inner diameter of the small hole is smaller than the end face diameter of the limiting nail 33, but larger than the diameter of the rod-shaped part of the limiting nail 33. This design allows the rod-shaped part of the limiting nail 33 to pass through the small hole, but limits the movement of the connecting plate 31 in the vertical direction. When the limiting nail 33 is fully inserted into the connecting hole 32, the connecting plate 31 is firmly suspended on the outside of the chiller 1. Through this design, the connecting plate 31 can not only be firmly It is firmly fixed on the chiller 1, and the installation and disassembly process also becomes simpler and more convenient. When the external filter device needs to be disassembled, the connecting plate 31 only needs to be lifted from the limiting nail 33 to make the rod-shaped part of the limiting nail 33 come out of the small hole, and the connecting plate 31 and the entire external filter device can be easily removed. In summary, the hanging connecting structure 3 realizes the stable installation and convenient disassembly of the external filter device on the outside of the chiller 1 through the cooperation of the T-shaped limiting nail 33 and the specially designed connecting hole 32, thereby improving the practicality and convenience of the entire device.

[0073] The hanging connection structure is connected through the limiting nails 33 and the connecting holes 32 on the connecting plate 31, without the need for complicated fasteners or screws, and the installation process is simple and quick. The T-shaped limiting nails 33 and the connected large and small holes ensure the stability of the connecting plate 31 in the horizontal and vertical directions, so that the external filter device can be firmly hung on the outside of the chiller 1. Since the connecting plate 31 is connected to the limiting nails 33 by hanging, when the external filter device needs to be maintained or replaced, the connecting plate 31 can be easily lifted for disassembly, reducing the complexity and time cost of maintenance.
