Description

Technical Field

[0001] This utility model relates to the field of air supply equipment technology, specifically to an adjustable air volume noise reduction and sand removal air supply equipment. Background Technology

[0002] Looking back at the design of previous factory ventilation systems, most focused only on the functional requirements of the equipment and the cleanliness of the air inside the factory, while neglecting the ability to control environmental factors such as temperature, humidity, ambient pressure difference, and equipment noise. Although traditional mixed-air dust collectors have solved the problems of air cleanliness and temperature control to some extent, their own structure limits their airflow pattern to ensure dust removal efficiency.

[0003] Traditional mixed-air dust collectors with constant airflow cannot accurately adapt to the fresh air volume requirements of factory equipment at different power levels, leading to a series of problems. First, when the fresh air volume in the factory far exceeds the actual air volume used by the equipment, it results in a significant waste of energy. Second, the air pressure inside the factory is higher than the external environmental pressure, creating an overpressure state. If this continues for a long time or exceeds the building's design pressure limit, it will pose a serious safety hazard. Third, the constant operation of a single unit will generate additional environmental noise when the factory equipment is operating at low power, affecting the comfort of the workers.

[0004] Therefore, there is an urgent need to develop a new type of factory environmental treatment equipment that can accurately regulate fresh air volume, effectively balance environmental pressure, and reduce operating noise. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the air supply equipment in the prior art is difficult to control the air volume and has serious noise pollution, and to provide an air supply equipment with adjustable air volume for noise reduction and sand removal.

[0006] To solve the above-mentioned technical problems, this utility model provides an adjustable airflow noise reduction and sand removal air supply device, which includes: a housing, on which a fresh air inlet and an air outlet are provided, and an air supply channel is formed between the fresh air inlet and the air outlet; an airflow adjustment mechanism, which includes a fresh air control valve and multiple main fans, the multiple main fans being arranged in the air supply channel and facing the fresh air inlet, the fresh air control valve being arranged at the fresh air inlet and connected to the multiple main fans; and a sand removal mechanism, which includes at least one sand removal module, the sand removal module being connected to a module control valve, the sand removal module being arranged between the main fans and the fresh air inlet, and the module control valve being connected to the fresh air control valve.

[0007] In one embodiment of this utility model, the fresh air control valve includes a valve plate, which is rotatably connected to the fresh air inlet to adjust the direction and / or opening degree of the fresh air inlet.

[0008] In one embodiment of the present invention, the air volume regulating mechanism further includes an air mixer, which is disposed between the air outlet and the main fan.

[0009] In one embodiment of the present invention, the sand removal mechanism further includes a sand discharge component, which is disposed inside the outer shell and is connected to the plurality of sand removal modules respectively.

[0010] In one embodiment of this utility model, the sand removal assembly includes a container, a sand removal fan, and a connecting pipe. The container is disposed below the sand removal module, the sand removal fan is disposed inside the container, one end of the connecting pipe is connected to the container, and the other end is connected to multiple sand removal modules respectively. A sand removal port is provided on one side of the container.

[0011] In one embodiment of the present invention, a plurality of the main fans are arranged in an array in the cross-sectional direction of the air supply channel, and the sand removal mechanism includes a plurality of sand removal modules, which are correspondingly arranged on the air inlet side of the plurality of main fans.

[0012] In one embodiment of this utility model, the noise reduction and sand removal air supply equipment further includes a control mechanism, wherein the fresh air control valve, the main fan, the sand removal module, and the module control valve are respectively connected to the control mechanism.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] The adjustable airflow noise reduction and sand removal air supply equipment of this utility model supplies air to the factory building through an air supply channel. During this process, the sand removal mechanism can purify and filter the air. Operators can adjust the actual airflow by independently controlling multiple main fans, thereby matching it with the actual air supply needs of the factory building. This not only reduces energy waste but also fundamentally avoids the risk of overpressure in the factory building. In addition, this application uses multiple main fans instead of traditional single air supply equipment, thus reducing noise impact under unnecessary high-power air supply conditions.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Example:

[0024] See Figures 1 to 3As shown, this embodiment provides an adjustable airflow noise reduction and sand removal air supply device, which includes: a housing 100, on which a fresh air inlet 110 and an air outlet 120 are provided, and an air supply channel is formed between the fresh air inlet 110 and the air outlet 120; an airflow adjustment mechanism 200, which includes a fresh air control valve and a plurality of main fans 210, which are disposed in the air supply channel and facing the fresh air inlet 110, and the fresh air control valve is disposed at the fresh air inlet 110 and connected to the plurality of main fans 210; and a sand removal mechanism 300, which includes at least one sand removal module 310, on which a module control valve 320 is connected, and the sand removal module 310 is disposed between the main fans 210 and the fresh air inlet 110, and the module control valve 320 is connected to the fresh air control valve.

[0025] In this application, the outer casing 100 serves two purposes: providing installation and connection space for other structures and protecting its internal structure to ensure the stability of the air supply process. It is preferably a rectangular box structure. The fresh air inlet 110 and the air supply outlet 120 are symmetrically arranged on opposite sides along the length of the outer casing 100, forming an air supply channel along its length. Furthermore, the outer casing 100 also includes a return air inlet 130, which communicates with the air supply channel. The fresh air inlet 110 communicates with the external environment, the air supply outlet 120 communicates with the factory's air intake duct, and the return air inlet 130 communicates with the factory's exhaust duct. Therefore, when supplying air to the factory, the return air inlet 130 is closed, and air from the external environment enters the air supply channel through the fresh air inlet 110, and then enters the factory through the air supply outlet 120. In this embodiment, the outer casing 100 also includes a rain cover 150, which is disposed above the fresh air inlet 110 to prevent rainwater, snow, etc. from entering the equipment and causing unnecessary corrosion to the internal structure of the equipment.

[0026] The air volume adjustment mechanism 200 in this embodiment includes four main fans 210, and the four main fans 210 can all act independently. Further, the four main fans 210 are arranged in an array in the cross-sectional direction of the air supply channel. In this embodiment, the opening range of the fresh air control valve changes synchronously corresponding to the number of the main fans 210 turned on. When the number of the main fans 210 turned on is 4, the fresh air control valve is in the fully open state. Correspondingly, when the number of the main fans turned on is 2, the opening degree of the fresh air control valve is 50% of the fully open state. Specifically, the fresh air control valve in this embodiment includes a valve plate, and the valve plate is rotatably connected to the fresh air inlet 110 to adjust the incoming direction and / or opening degree of the fresh air inlet 110. It should be noted that when the incoming air flow changes, especially in the case of low wind speed, the dust carried in the air flow is likely to fall to the bottom of the mixed air area due to insufficient power, and the accumulated dust over a long time will lead to dust accumulation, affecting the normal operation of the system and the sand removal effect. Therefore, in this application, the incoming direction and the opening degree of the fresh air inlet 110 are flexibly adjusted by the rotation of the valve plate. When the air flow moves to the mixed air area of the fresh air and the return air pipe, this adjustable opening angle can ensure that the air flow maintains a relatively high wind speed. Under the action of a relatively high wind speed, the dust carried in the air flow can stably and smoothly enter the interior of the sand removal module 310, thereby ensuring that the sand removal module 310 always maintains a relatively high sand removal efficiency.

[0027] Further specifically, the four main fans 210 are placed in a "field" shape. When the dust-containing air flow enters the mixed air area, the dust in the air flow moves in a parabolic shape, and the two main fans 210 below can stably suck the dust, preventing the dust from falling to the bottom of the mixed air area.

[0028] Specifically, for the four main fans 210 provided in this application, the noise reduction and sand removal air supply equipment with adjustable air volume correspondingly has four gears, and each gear corresponds to one main fan 210. Thus, this equipment can adjust the suitable incoming air volume according to the actual use requirements. In different embodiments, the number and the installation position of the main fans 210 can be adaptively adjusted according to the actual use requirements, and the present utility model does not make specific limitations thereto.

[0029] In this application, the air mixer 220 can disperse and guide the originally possibly concentrated or disordered air flow, prompting the air flow to be more evenly distributed on the pipe cross-section, and further making the finally output air flow more uniform and stable in parameters such as temperature and humidity, improving the air supply quality.

[0030] In this embodiment, the sand removal mechanism 300 includes multiple sand removal modules 310, which are correspondingly arranged on the air inlet side of multiple main fans 210. Each main fan 210 has a corresponding sand removal module 310 on its air inlet side, allowing for individual purification of the airflow entering each main fan 210. Since the air inlet conditions of different main fans 210 may differ, such as airflow velocity and dust content, individually setting up sand removal modules 310 allows for more precise and efficient removal of dust from the airflow based on the actual air inlet characteristics of each main fan 210. Furthermore, the multiple sand removal modules 310 work collaboratively; even if one module malfunctions, the others can continue to operate, maintaining the system's basic sand removal function and improving the reliability and stability of the entire sand removal mechanism 300.

[0031] Based on the above structural configuration, the noise reduction and sand removal air supply equipment described in this embodiment also includes a control mechanism. The fresh air control valve, the main fan 210, the sand removal module 310, and the module control valve 320 are respectively connected to the control mechanism. Specifically, upon initial startup, the control mechanism will first perform a self-check according to the factory-preset program to ensure that each structure can work normally. Afterward, it can automatically adjust the fresh air control valve according to the outdoor fresh air temperature, the indoor set temperature, and the actual indoor temperature, and implement control during actual use. During actual use, operators can control the above structure in real time through the control mechanism, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment. Furthermore, the outer casing 100 also includes a junction box 140, which is disposed inside the outer casing 100 for connecting to external electrical control equipment.

[0032] The sand removal mechanism 300 in this embodiment also includes a sand discharge component 330, which is disposed inside the outer casing 100 and communicates with the plurality of sand removal modules 310. It is used to continuously separate sand and dust from the airflow. The sand discharge component 330, connected to each sand removal module 310, can collect the sand and dust in a timely manner, preventing sand and dust accumulation within the sand removal modules 310 and preventing blockages that could affect the separation efficiency and normal operation of the sand removal modules 310. Centralized processing also facilitates the subsequent unified disposal of the sand and dust.

[0033] Furthermore, the sand removal component 330 includes a storage box 334, a sand removal fan 331, and a connecting pipe 332. The storage box 334 is located below the sand removal module 310, and the sand removal fan 331 is located inside the storage box 334. One end of the connecting pipe 332 is connected to the storage box 334, and the other end is connected to multiple sand removal modules 310. A sand discharge port 333 is provided on one side of the storage box 334. The storage box 334 provides a centralized storage space for sand and dust. The sand removal fan 331, located inside the storage box 334, serves as the core power source for sand removal. By generating strong suction, it quickly draws the sand and dust separated from the sand removal modules 310 into the storage box 334 through the connecting pipe 332, ensuring timely discharge of sand and dust and preventing accumulation within the sand removal modules 310 that could affect sand removal efficiency. The sand discharge port 333 facilitates the centralized cleaning of collected sand and dust. When the sand and dust in the container 334 accumulate to a certain amount, the staff can quickly discharge the sand and dust through the sand discharge port 333, which is convenient for maintenance and operation and can maintain the continuous operation of the sand discharge component 330.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
