Description

Technical Field

[0001] The present application relates to the technical field of spray cleaning structures, and in particular to a spray cleaning structure and a sludge dryer. Background Art

[0002] In recent years, with the development of sludge drying technology, low-temperature sludge drying has gradually become one of the mainstream technologies for sludge treatment and disposal in my country. Low-temperature sludge drying technology is a treatment technology that circulates hot dry air generated by the low-temperature drying system within the system to dry the sludge evenly distributed on the mesh belt.

[0003] In current sludge drying equipment, when sludge dust enters heat exchange devices such as surface coolers, evaporators, and condensers, it encounters humid air and causes scale and corrosion, leading to refrigerant leakage and high-temperature and high-pressure alarms in the compressor, affecting the service life of the compressor and reducing the overall equipment utilization rate. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a spray cleaning structure and a sludge dryer, which can effectively clean the surface and interior of the heat exchanger through two spray components, ensure stable heat exchange efficiency, and thus ensure stable operation of the entire equipment.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] On the one hand, a spray cleaning structure and a sludge dryer are provided, comprising: a frame, a heat exchanger, a first spray assembly, a second spray assembly and a pipeline assembly, wherein the heat exchanger is installed in the frame, and the first spray assembly and the second spray assembly are respectively connected to the water supply equipment through the pipeline assembly, the first spray assembly is installed on the upper part of the air inlet surface of the heat exchanger, and can rotate relative to the heat exchanger to spray and clean the air inlet surface of the heat exchanger, and the second spray assembly is arranged above the heat exchanger and can spray and clean the heat exchange layer in the middle of the heat exchanger.

[0007] Furthermore, the first spray assembly includes a driving member, a main water pipe and a plurality of first spray members, one end of the main water pipe is rotatably connected to the water outlet end of the pipeline assembly, and the other end is connected to the driving shaft of the driving member, and the plurality of first spray members are arranged at intervals along the length direction of the main water pipe.

[0008] Furthermore, it also includes a first bracket, which is installed in the frame and has one end extending toward the main water pipe to form an arc-shaped installation position for supporting the main water pipe.

[0009] Furthermore, it includes a second bracket, which is installed in the frame, and the driving member is installed on the second bracket.

[0010] Furthermore, the driving component is a servo motor.

[0011] Furthermore, the driving member is a rotating rod, one end of the rotating rod is fixedly connected to the main water pipe, and the other end is formed with a handle.

[0012] Furthermore, the second spray assembly includes at least two water distribution pipes, the two water distribution pipes are respectively connected to the water outlet end of the pipeline assembly, and each of the water distribution pipes is provided with a plurality of second spray parts capable of spraying water downward.

[0013] Furthermore, the pipeline assembly includes a first water pipe and a second water pipe, both of which are connected to water supply equipment, the water outlet end of the first water pipe is connected to the first spray assembly, and the water outlet end of the second water pipe is connected to the second spray assembly.

[0014] Furthermore, it also includes a third bracket, which is installed on the frame and fixedly connected to the second water pipe.

[0015] On the other hand, a sludge dryer is also provided, comprising the spray cleaning structure as described in any one of the above items.

[0016] The beneficial effects of the present application are as follows: the structure includes a frame, a heat exchanger, a first spray assembly, a second spray assembly and a piping assembly. The heat exchanger is firmly mounted in the frame and is responsible for the core heat exchange task, while the first spray assembly is cleverly mounted on the upper part of the air inlet surface of the heat exchanger. Its design allows it to rotate relative to the heat exchanger, thereby achieving comprehensive spray cleaning of the air inlet surface and effectively removing dust and dirt attached to the surface. At the same time, the second spray assembly is carefully arranged directly above the heat exchanger, directly aiming at the heat exchange layer for deep cleaning. When the cleaning program is started, the two groups of spray assemblies work separately or simultaneously. The first spray assembly cleans the air inlet surface by rotating spray, and the second spray assembly cleans the inside of the heat exchange layer by high-pressure spray or conventional running water cleaning, ensuring that every place is thoroughly cleaned. During the cleaning process, the water flow not only flushes away the deposits, but also helps to discharge or collect and process these dirt, keeping the internal environment of the equipment clean.

[0017] Through such an efficient spray cleaning mechanism, this application significantly improves the heat exchange efficiency of the heat exchanger and reduces the problem of reduced heat exchange performance due to fouling. At the same time, it also effectively extends the service life of the equipment, especially avoiding common faults such as refrigerant leakage and compressor high temperature and high pressure alarms caused by fouling corrosion, thereby improving the overall stability and reliability of the equipment. In addition, the structure also embodies the design concept of energy conservation and environmental protection. By optimizing heat exchange efficiency and adopting a water-saving design for the spray system, energy consumption and water waste are reduced. Most importantly, its ease of maintenance also greatly reduces the subsequent operating costs, providing a strong guarantee for the continued efficient operation of sludge drying technology.

[0025] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0026] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0028] like Figure 1-Figure 5 As shown, this embodiment provides a spray cleaning structure and a sludge dryer, including: a frame 1, a heat exchanger 2, a first spray assembly 3, a second spray assembly 4 and a pipe assembly 5. The heat exchanger 2 is installed in the frame 1, and the first spray assembly 3 and the second spray assembly 4 are respectively connected to the water supply equipment through the pipe assembly 5. The first spray assembly 3 is installed on the upper part of the air inlet surface of the heat exchanger 2, and can be rotated relative to the heat exchanger 2 to spray and clean the air inlet surface of the heat exchanger 2. The second spray assembly 4 is arranged above the heat exchanger 2 and can spray and clean the heat exchange layer in the middle of the heat exchanger 2.

[0029] Based on the above scheme, the first spray assembly 3 and the second spray assembly 4 are connected to the water supply equipment through the pipe assembly 5 to ensure a continuous and stable supply of cleaning water. The first spray assembly 3 is installed on the upper part of the air inlet surface of the heat exchanger 2 and is designed to rotate relative to the heat exchanger 2. This allows for all-round spray cleaning of the air inlet surface of the heat exchanger 2. The second spray assembly 4 is set directly above the heat exchanger 2, directly aimed at the heat exchange layer inside the heat exchanger 2, ensuring that it can penetrate deep into the heat exchanger 2 for cleaning. When dust and dirt may accumulate on the surface and inside of the heat exchanger 2 during the sludge drying process, the spray cleaning system is started. The first spray assembly 3 starts working and evenly sprays the air inlet surface of the heat exchanger 2 through the rotating spray head, effectively removing dust and dirt attached to the surface. The intensity and angle of the spray can be controlled by adjusting the rotation speed of the spray assembly and the amount of spray water. Simultaneously or subsequently, the second spray assembly 4 is activated, spraying directly onto the heat exchange layer within heat exchanger 2. Using high-pressure water or mist, it deeply cleans accumulated dirt and ensures unobstructed clearance between the heat exchange layers. During the cleaning process, dirt removed by the water flow is discharged from the system or collected by a collection device. Regular or as-needed spray cleaning maintains the cleanliness of heat exchanger 2 and reduces the loss of heat exchange efficiency caused by scale accumulation. This prevents problems such as refrigerant leaks and compressor high-temperature and high-pressure alarms caused by scale corrosion, extending the equipment's service life and improving overall equipment utilization.

[0030] Furthermore, the first spray assembly 3 includes a drive member 301, a main water pipe 302, and a plurality of first spray members 303. One end of the main water pipe 302 is rotatably connected to the water outlet end of the pipeline assembly 5, and the other end is connected to the drive shaft of the drive member 301. The plurality of first spray members 303 are arranged at intervals along the length of the main water pipe 302. The drive member 301 serves as the core power source and is connected to one end of the main water pipe 302 through its drive shaft, providing the necessary rotational power for the entire spraying process. This design enables the main water pipe 302 to rotate around its axis, thereby driving the nozzles installed thereon to perform a full range of spraying operations. The main water pipe 302 is a key component for transporting cleaning water. One end of the main water pipe 302 is rotatably connected to the water outlet end of the pipeline assembly 5 to ensure that it can still stably receive cleaning water from the water supply equipment during the rotation process. The other end is firmly connected to the drive shaft of the drive member 301 to achieve power transmission and rotation control. Along the length of the main water pipe 302, multiple first spray parts 303 are arranged at intervals to form a dense spray network. The arrangement of these nozzles has been carefully calculated to ensure that the entire air inlet surface of the heat exchanger 2 can be covered during the rotation process without leaving any dead corners. Each nozzle has excellent spraying performance and can spray cleaning water at appropriate pressure and angle to effectively wash away dust and dirt attached to the surface of the heat exchanger 2.

[0031] The first spraying member 303 is specifically a nozzle, which is selected to be a type that can efficiently spray water to form a fine water mist or a strong water column to better wash away dust, dirt and other impurities on the air inlet surface of the heat exchanger 2.

[0032] Furthermore, in order to ensure the stability and reliability of the first spray assembly 3 during the spray cleaning process, the present application also designs a first bracket 6 as a key supporting structure. The first bracket 6 is installed inside the frame 1, and its design fully considers the working characteristics and spatial layout requirements of the spray assembly. The first bracket 6, one end of which extends toward the main water pipe 302, cleverly forms an arc-shaped mounting position 601. This arc-shaped mounting position 601 not only matches the shape of the main water pipe 302, but also provides sufficient support area to ensure that the main water pipe 302 can maintain stable operation during rotation and will not shake or deflect due to its own weight or water flow impact. With the support of the first bracket 6, the main water pipe 302 can be firmly installed in the frame 1, and its rotating spraying action becomes smoother and more precise. At the same time, this design also reduces the damage that may be caused to the main water pipe 302 and the nozzle due to vibration and impact, thereby extending the service life of the spray assembly.

[0033] In the process of further improving the spray cleaning structure, the present application also introduces a second bracket 7 as an important auxiliary support component. The second bracket 7 is installed inside the frame 1. Its main function is to carry and fix the driver 301, ensuring the stability and reliability of the driver 301 during operation. By installing the driver 301 on the second bracket 7, the vibration and impact force generated by the driver 301 during operation can be effectively dispersed, avoiding these forces from being directly transmitted to the frame 1 or other components, thereby reducing the overall vibration and noise of the equipment. This design not only extends the service life of the driver 301, but also improves the stability and durability of the entire spray cleaning structure.

[0034] Specifically, the drive element 301 is a servo motor. As a high-precision, high-performance electric motor, the servo motor offers advantages such as fast response, high control accuracy, and stable and reliable operation, making it ideal for applications requiring precise control and stable operation. In the spray cleaning structure, the servo motor is connected to the main water pipe 302 via its drive shaft, providing rotational power to the spray assembly. Through precise servo control, the servo motor ensures that the main water pipe 302 rotates at a predetermined speed and angle, thereby achieving comprehensive and uniform spray cleaning of the air inlet surface of the heat exchanger 2.

[0035] In addition, the servo motor also has multiple functions such as overload protection, speed control, and position control, and can be flexibly adjusted according to actual working conditions and cleaning needs. This intelligent control method not only improves cleaning efficiency and quality, but also reduces energy consumption and operating costs.

[0036] As an optional specific implementation scheme, the driving member 301 in the spray cleaning structure of the present application can be designed in the form of a rotating rod. This design provides a simpler, more intuitive and more cost-effective solution in specific scenarios. One end of the rotating rod is fixedly connected to the main water pipe 302 to ensure that the two can move synchronously during the rotation process. The other end is cleverly designed into a handle shape, which is convenient for the operator to directly hold and apply rotational force. By manually rotating the handle, the operator can easily control the rotating rod and the main water pipe 302 connected thereto to perform a rotary spraying operation. Although this manual drive method may be slightly inferior in accuracy and efficiency compared to automated drive methods such as servo motors, it has the advantages of simple structure, easy maintenance and low cost. In some application scenarios where the cleaning accuracy requirements are not particularly high or the degree of automation is limited, a manual rotating rod is still a very practical and economical choice.

[0037] Furthermore, the manual rotating rod offers a degree of flexibility. Operators can adjust the rotation speed and force at any time based on actual conditions and cleaning requirements to achieve optimal cleaning results. This also allows for rapid response in emergency situations. In summary, designing the drive member 301 as a rotating rod with a handle is an alternative implementation in a spray cleaning system that meets basic cleaning requirements while also taking into account factors such as cost-effectiveness and flexibility.

[0038] In some embodiments, in order to further improve the coverage and effect of spray cleaning, the second spray assembly 4 is designed to include a structure of at least two water distribution pipes 401. These two (or more) water distribution pipes 401 are independently connected to the water outlet end of the pipeline assembly 5 to ensure that each can stably obtain the cleaning water source. A plurality of second spray parts 402 are carefully arranged on each water distribution pipe 401. These nozzles are designed to spray water downward to directly spray and clean the heat exchange layer inside the heat exchanger 2. By reasonably controlling the arrangement density and spray angle of the nozzles, it can be ensured that the cleaning water flow can evenly cover every corner of the heat exchange layer and effectively remove scale and dirt. The design of multiple water distribution pipes 401 not only increases the coverage area of ​​spray cleaning, but also improves the uniformity and efficiency of cleaning. At the same time, since each water distribution pipe 401 can work independently, the water spray volume and spray time of each water distribution pipe 401 can be adjusted as needed in actual applications to achieve the best cleaning effect.

[0039] In addition, this design also has certain flexibility and scalability. Along with the expansion of equipment scale or the increase of cleaning demand, the quantity of water distribution pipes 401 can be easily increased or its layout can be adjusted to meet different cleaning demands.

[0040] Optionally, the pipeline assembly 5 includes a first water pipe 501 and a second water pipe 502. Both the first water pipe 501 and the second water pipe 502 are connected to a water supply device. The outlet of the first water pipe 501 is connected to the first spray assembly 3, and the outlet of the second water pipe 502 is connected to the second spray assembly 4. The first water pipe 501, as one of the main delivery pipes, has its outlet directly connected to the first spray assembly 3. In this way, when the cleaning process is initiated, cleaning water from the water supply device can be quickly and stably delivered to the first spray assembly 3 through the first water pipe 501, providing comprehensive spray cleaning for the air inlet surface of the heat exchanger 2. Meanwhile, the second water pipe 502 is responsible for providing cleaning water to the second spray assembly 4. Its outlet is connected to the second spray assembly 4, ensuring that the second spray assembly 4 can obtain sufficient cleaning water for spray cleaning inside the heat exchange layer when needed. This separate design allows the first and second water pipes 501 and 502 to operate independently without interfering with each other. This not only improves the stability and reliability of the cleaning process, but also allows operators to more easily adjust the cleaning parameters and operating time of each spray component according to actual needs. The second spray element 402 can be a nozzle or a long, strip-shaped spray pipe with multiple outlet holes below it to achieve uniform spraying.

[0041] The design also takes into account system scalability and maintainability. As equipment scales up or cleaning needs increase, additional water pipes and spray components can be easily added to expand the system's cleaning capacity. Furthermore, the connections between various components are designed to be easily disassembled and replaced, facilitating subsequent maintenance and repair.

[0042] It is worth mentioning that it also includes a third bracket 8, which is mounted on the frame 1 and is fixedly connected to the second water pipe 502. This solution ensures that the second water pipe 502 can maintain a stable posture during the process of transporting cleaning water and is not disturbed by external factors (such as vibration, impact, etc.). Through the support of the third bracket 8, the second water pipe 502 can more reliably transport the cleaning water to the second spray assembly 4, ensuring the continuity and effectiveness of the spray cleaning. Moreover, the third bracket 8 also plays a role in dispersing the load. It helps to evenly distribute the gravity of the second water pipe 502 and its internal water flow to the frame 1, thereby reducing the load-bearing pressure of individual components and extending the service life of the entire spray cleaning system. In terms of structural design, the third bracket 8 is usually made of sturdy and durable materials, such as stainless steel or aluminum alloy. These materials not only have excellent mechanical properties, but also have good corrosion resistance and aging resistance, and can maintain stable performance in harsh working environments.
