Description

Technical Field

[0001] This utility model relates to the field of integrated refrigeration station technology, specifically to an integrated refrigeration station structure. Background Technology

[0002] With the rapid development of building energy conservation and prefabricated construction technologies, integrated chiller plants have been widely used in data centers, commercial complexes, and industrial refrigeration due to their advantages such as high integration, energy efficiency, and convenient installation. Integrated chiller plants prefabricate and integrate chiller units, pumps, pipelines, valves, control systems, and other equipment into modular enclosures in the factory, thus realizing the productization of chiller rooms.

[0003] A search revealed patent CN219829567U, which describes a central air conditioning integrated chiller station. The station includes a base plate, an integrated control box fixedly mounted on the upper surface of the base plate, and two cooling towers fixedly mounted on the upper surface of the integrated control box. Two rollers are rotatably mounted on both sides of the integrated control box. A covering device is provided on the side wall of each cooling tower. The covering device includes a fixed frame fixedly mounted on the side wall of the cooling tower, with a drive rod threaded through the internal threads of the fixed frame. This invention, by setting up a covering device, facilitates flexible covering of the cooling tower ports using mesh, reducing the likelihood of dirt adhering to internal components such as fan blades, which are typically left open. This reduces energy consumption during operation of the central air conditioning integrated chiller station and further improves its performance.

[0004] Cooling towers are the core heat dissipation unit of the integrated chiller plant's thermal cycle, and their operational efficiency and maintainability determine the chiller plant system's energy efficiency ratio and long-term operational reliability. Regarding the issue of external impurities easily entering through the top opening, existing technology proposes installing protective mesh screens, but this solution has significant limitations. First, the mesh screens are easily clogged by suspended matter, especially under high temperature and humidity conditions, where the deposits combine with saturated water vapor to form stubborn dirt that is difficult to clean. Second, cooling towers are often installed on rooftops or high platforms, requiring maintenance personnel to work at heights in harsh environments, increasing manual maintenance costs and safety risks, and making it difficult to ensure the continuous and effective implementation of protective measures. This makes it difficult to implement the protective design in actual operation and maintenance, and may even affect the system's heat dissipation and operational stability. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated refrigeration station structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated refrigeration station structure, including an integrated control box, a cooling tower for heat dissipation, and a forced ventilation fan;

[0007] A filter screen is fixedly installed on the top of the cooling tower. A scraper is rotatably connected to the outer surface of the filter screen via a drive assembly. A slag discharge assembly is provided on one side of the scraper.

[0008] As a further preferred embodiment of this technical solution, the drive assembly includes a bottom connecting shaft fixedly installed on the scraper, the connecting shaft being embedded in the filter screen, and the bottom of the connecting shaft passing through the filter screen and embedded in the fan.

[0009] A connecting block is fixedly connected to the outer wall of the connecting shaft. The connecting blocks are evenly distributed in a ring array and are slidably installed inside the fan.

[0010] As a further preferred embodiment of this technical solution, a base plate is fixedly installed on the outer wall of the connecting shaft, and a top pressure plate is elastically installed on the top of the base plate, with the top pressure plate positioned at the bottom end of the filter screen.

[0011] As a further preferred embodiment of this technical solution, the slag discharge assembly includes a slag discharge plate slidably installed on one side of the scraper, and a reciprocating screw is threadedly connected to one side of the top of the slag discharge plate, the reciprocating screw being rotatably installed inside the scraper;

[0012] The outer wall of the scraper is slidably connected to an installation ring, and the installation ring has slag discharge ports evenly distributed in a ring array. The installation ring is fixedly installed on the outer wall of the filter screen, and a ring rack is fixedly installed inside the installation ring. A gear is meshed on the top of the ring rack, and the gear is fixedly installed on one end of the reciprocating screw.

[0013] This utility model provides an integrated refrigeration station structure, which has the following beneficial effects:

[0014] (1) This utility model cleans the outer surface of the filter screen by scraping. During operation, the scraper continuously rotates to remove the adhering substances on the surface of the filter screen, which can delay the clogging of the filter screen. This not only helps to maintain a relatively stable ventilation volume and avoid the rapid decline of system performance due to clogging, but also greatly reduces the frequency of manual cleaning of the filter screen, reduces the labor and time costs of long-term maintenance, thereby improving the heat dissipation and operational stability of the system.

[0015] (2) By setting up the slag discharge assembly, the scraper rotates in the mounting ring during operation, which drives the gear to rotate in the mounting ring. The gear rotates by meshing with the ring rack. The rotation of the gear drives the rotation of the reciprocating screw. When the reciprocating screw rotates, it drives the slag discharge plate to move back and forth, scraping the impurities attached to the side wall of the scraper to both ends and finally discharging them from the slag discharge port, forming a cleaning closed loop to reduce the system's dependence on manual cleaning of accumulated impurities, and the degree of automation is higher.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, an integrated refrigeration station structure includes an integrated control box 1, a cooling tower 2 for heat dissipation, and a forced ventilation fan 3.

[0024] A filter screen 4 is fixedly installed on the top of the cooling tower 2. A scraper 5 is rotatably connected to the outer surface of the filter screen 4 via a drive assembly. A slag discharge assembly is provided on one side of the scraper 5.

[0025] The existing patent CN219829567U discloses a central air conditioning integrated refrigeration station. This patent discloses the integrated control box 1, cooling tower 2, fan 3 and filter 4 proposed in this application. The technical means will not be described in detail here.

[0026] During operation, the scraper 5 continuously rotates to remove the deposits on the surface of the filter screen 4, which can delay the clogging of the filter screen 4. This not only helps to maintain a relatively stable airflow and prevent the system performance from rapidly declining due to clogging, but also significantly reduces the frequency of manual cleaning of the filter screen 4, reducing the labor and time costs of long-term maintenance, thereby improving the system's heat dissipation and operational stability.

[0027] like Figures 1 to 4 As shown, the drive assembly includes a bottom connecting shaft 6 fixedly installed on the scraper 5. The connecting shaft 6 is embedded in the filter screen 4, and the bottom of the connecting shaft 6 passes through the filter screen 4 and is embedded in the fan 3.

[0028] A connecting block 9 is fixedly connected to the outer wall of the connecting shaft 6. The connecting blocks 9 are evenly distributed in a ring array and are slidably installed inside the fan 3.

[0029] By directly utilizing the rotational power of the main shaft of the blower, there is no need to equip it with an additional motor, power supply and control system, which reduces additional energy consumption and electrical complexity;

[0030] The cleaning action of scraper 5 is naturally synchronized with the start-up, shutdown and speed of fan 3. As long as fan 3 is providing heat dissipation airflow to cooling tower 2, the cleaning work is ongoing, achieving uninterrupted passive maintenance.

[0031] When it is necessary to remove the filter screen 4 for maintenance, the connecting block 9 can be slid out of the fan 3 and taken out for maintenance together.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, a base plate 7 is fixedly installed on the outer wall of the connecting shaft 6, and a top pressure plate 8 is elastically installed on the top of the base plate 7. The top pressure plate 8 is located at the bottom end of the filter screen 4.

[0033] The bottom plate 7 and the top pressure plate 8 are staggered with the scraper 5, and the bottom plate 7 and the top pressure plate 8 are located on one side of the scraper 5 in the forward direction.

[0034] The top pressure plate 8 is flexibly designed, and the bottom plate 7 and the top pressure plate 8 are elastically connected by springs.

[0035] As the scraper 5 moves forward, the bottom pressure plate 8 pushes the filter screen 4 upward, causing localized micro-deformation or vibration of the filter screen 4. This helps to loosen wet, sticky dirt embedded deep in the mesh or that is firmly adhered, making it easier for the scraper 5 to carry it away, thereby enhancing cleaning power and removing stubborn dirt.

[0036] The flexible top plate 8 provides upward support, which can prevent the scraper 5 from directly crushing the filter screen 4 with hard pressure. Especially for materials such as metal wire mesh, it can play a buffering and protective role and extend the life of the filter screen 4.

[0037] like Figures 1 to 5 As shown, the slag discharge assembly includes a slag discharge plate 14 that is slidably installed on one side of the scraper 5. A reciprocating screw 11 is threadedly connected to one side of the top of the slag discharge plate 14. The reciprocating screw 11 is rotatably installed inside the scraper 5.

[0038] The outer wall of the scraper 5 is slidably connected to an installation ring 10. The installation ring 10 has slag discharge ports evenly distributed in a ring array. The installation ring 10 is fixedly installed on the outer wall of the filter screen 4. The installation ring 10 is fixedly installed inside the installation ring 10. The top of the ring rack 13 is meshed with a gear 12. The gear 12 is fixedly installed at one end of the reciprocating screw 11.

[0039] During operation, the scraper 5 rotates within the mounting ring 10, driving the gear 12 to rotate within the mounting ring 10. Through the meshing of the ring rack 13, the gear 12 rotates on its own axis. The rotation of the gear 12 drives the rotation of the reciprocating screw 11. When the reciprocating screw 11 rotates, it drives the slag discharge plate 14 to move back and forth, scraping the impurities attached to the side wall of the scraper 5 to both ends and finally discharging them from the slag discharge port, forming a closed-loop cleaning system to reduce the system's reliance on manual cleaning of accumulated impurities, resulting in a higher degree of automation.

[0040] It also prevents the dirt accumulated by the scraper from being dispersed or clump together again due to airflow, vibration or moisture, thus clogging the cleaned area again and consolidating the cleaning effect.

[0041] This utility model provides an integrated refrigeration station structure, the specific working principle of which is as follows:

[0042] During operation, the rotational power of the fan 3 main shaft drives the connecting shaft 6 to rotate, and the rotation of the connecting shaft 6 drives the scraper 5 to rotate, so that the scraper 5 continuously rotates to scrape off the adhering substances on the surface of the filter screen 4.

[0043] When the scraper 5 scrapes forward, the top pressure plate 8 at the bottom pushes the filter screen 4 upward, causing the filter screen 4 to undergo localized micro-deformation or vibration, making it easier for impurities embedded deep in the mesh to be carried away by the scraper 5.

[0044] When the scraper 5 rotates within the mounting ring 10, it drives the gear 12 to rotate within the mounting ring 10. The gear 12 rotates due to the meshing of the ring rack 13. The rotation of the gear 12 drives the rotation of the reciprocating screw 11. When the reciprocating screw 11 rotates, it drives the slag discharge plate 14 to move back and forth, scraping the impurities attached to the side wall of the scraper 5 to both ends and finally discharging them from the slag discharge port within the mounting ring 10, thus forming a closed cleaning loop.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
