[0002] Chemical HVAC fans are widely used in the chemical industry to provide hot air to meet the temperature and ventilation requirements of the chemical production process. Such fans usually have explosion-proof and corrosion-resistant characteristics to meet the special requirements of the chemical environment. At the same time, they can effectively remove harmful gases and ensure the air quality in the workplace.

[0003] In a chemical environment, the air may contain various tiny particles, dust, fibers or other pollutants. If these impurities are sucked into the fan system, they will not only affect the operating efficiency of the fan, but may also cause wear or damage to the internal components of the fan. Therefore, chemical HVAC fans are usually equipped with filters to capture impurities in the air, maintain the cleanliness of the air, and thus extend the service life of the fan.

[0004] In the actual operation process, when the trapped impurities need to be cleaned, the machine needs to be shut down and disassembled for cleaning. The shutdown and disassembly not only makes the cleaning work inconvenient, but also causes the air purification to be interrupted after the shutdown, affecting the purification efficiency.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-3 As shown, a chemical heating general air purification treatment device includes an outer shell 1, an air inlet duct 10 and an air outlet duct 12 connected at both ends of the outer shell 1, a spherical duct 11 connected to the air inlet duct 10 is arranged in the outer shell 1, in this embodiment, the air inlet duct 10 is located at the center of the spherical duct 11, ensuring that the wind from the air inlet duct 10 blows toward the center of the spherical duct 11, and an air duct one 13 and an air duct two 14 are connected between the spherical duct 11 and the air outlet duct 12. In this embodiment, the air duct one 13 and the air duct two 14 are L-shaped, and the air duct one 13 and the air duct two 14 are eccentrically arranged on the spherical duct 11, and the air duct one 13 is located above the air duct two 14.

[0025] like Figure 2-4As shown, a rotatable filter plate assembly is fitted in the spherical channel 11, and the filter plate assembly includes an impurity filter plate 2, a solid plate 3 and a connecting column 4. In order to ensure that impurities do not flow to the back side of the filter plate assembly relative to the airflow direction and enhance the sealing, in this embodiment, a rubber sealing layer is provided on the outer wall of the connecting column 4, wherein the rubber sealing layer slides with the inner wall of the spherical channel 11, and a plurality of filter holes 20 are provided on the impurity filter plate 2 for airflow to pass through. The solid plate 3 is located on one side of the impurity filter plate 2 for obstructing the airflow and changing the direction of the airflow through the filter holes 20. The solid plate 3 and the impurity filter plate 2 are enclosed and connected by the connecting column 4, and a guide gap is formed between the solid plate 3 and the impurity filter plate 2, and a guide air duct 5 connected to the guide gap is provided on the connecting column 4.

[0026] like Figure 2-4 As shown, the outer wall of the connecting column 4 is fixedly connected with the rotating shaft 6. In this embodiment, one end of the rotating shaft 6 passes through and rotates on the inner wall of the spherical channel 11. In this embodiment, the connection between the rotating shaft 6 and the inner wall of the spherical channel 11 is rotatably connected through a sealed bearing to ensure the sealing of the rotating connection. The outer side of the outer shell 1 is provided with a driving member for driving the rotating shaft 6 to rotate, wherein the driving member is any one of a rotating motor or a handle, and is not limited to the above two methods. Any component that can drive the rotating shaft 6 to rotate is acceptable. However, when it is a handle, a handle bolt for limiting the position is installed on the handle, and the outer wall of the outer shell 1 is provided with a threaded groove corresponding to the handle bolt, so as to facilitate locking the position of the handle as needed.

[0027] like Figure 2-3 and Figure 5 As shown, an impurity intercepting member is installed on the air duct 13, which is used to intercept impurities in the air flow and facilitate the collection of impurities later. The impurity intercepting member includes a sinking groove 7, a filter plate 8 and a blocking member 9. The sinking groove 7 is opened at the top of the outer shell 1 and is vertically arranged with the air duct 13, and the depth of the sinking groove 7 is greater than the depth of the air duct 13. The filter plate 8 is arranged in the sinking groove 7, and a gap for collecting impurities is left between the filter plate 8 and the inner wall of the sinking groove 7;

[0028] An impurity collecting frame 80 is fixedly connected to the side wall of the filter plate 8. The impurity collecting frame 80 is located in the gap and is used to recover the impurities filtered by the filter plate 8. A wedge-shaped air guide protrusion 130 is provided at the connection between the air duct 13 and the sinking groove 7 to form an oblique downward wind flow, which is convenient for blowing the impurities trapped on the surface of the filter plate 8 to the impurity collecting frame 80. The sealing member 9 is fixedly connected to the top of the filter plate 8, and the shape of the sealing member 9 is the same as the notch of the sinking groove 7, which is used for sealing to prevent the outside air from interfering with the airflow in the air duct 13.

[0029] The working principle of the utility model is: the driving shaft 6 drives the filter plate assembly to rotate to Figure 2In the state, after the airflow passes through the air inlet duct 10 and blows toward the impurity filter plate 2 in the spherical channel 11, the impurities in the airflow are intercepted by the impurity filter plate 2. Figure 2 In the inclined state, the trapped impurities will fall into the spherical channel 11 below the impurity filter plate 2, and the airflow that has trapped the impurities through the impurity filter plate 2 enters the guide gap between the solid plate 3 and the impurity filter plate 2, and then flows out through the guide air duct 5, and then flows to the outlet duct 12 through the air duct 2 14; when it is necessary to clean the impurities, the drive shaft 6 drives the filter plate assembly to rotate in the opposite direction to Figure 3 In the process of rotation, the impurities in the spherical channel 11 are pushed, so that the trapped impurities are located on the upper surface of the impurity filter plate 2. At the same time, the upper surface of the impurity filter plate 2 is connected with the air duct 13, and the connection with the air duct 2 14 is blocked. Under the action of the airflow, the impurities trapped by the impurity filter plate 2 flow along the upper surface of the impurity filter plate 2 into the air duct 13, and are then trapped and collected by the impurity trapping member. After the collection is completed, the driving member rotates the rotating shaft 6 in the opposite direction, so that the impurity filter plate 2 returns to the position of Figure 2 state, continue to perform the diversion work under the normal working state, then pull out the blocking member 9 from the sinking groove 7, and then take out the impurities collected in the impurity collection frame 80.

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
