Technical Field

[0001] The utility model relates to the technical field of warm pass filtering, in particular to a warm pass filtering device. Background Art

[0002] A HVAC fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. A HVAC fan is a type of HVAC equipment. HVAC equipment mainly includes three professional directions: heating, ventilation and air conditioning. It is mainly used for indoor heating and cooling and ventilation. It is a common household appliance that can quickly increase the indoor air temperature and provide a relatively fast heating effect. During the heating process, it can also ventilate and improve indoor air quality.

[0003] At present, the HVAC fans in factories use a single vertical filter to filter out impurities in the airflow. The HVAC in factories needs to transmit the airflow through air ducts.

[0004] However, existing filters are difficult to install and disassemble based on the shape of the air duct. Since the filter is designed based on the shape of the air duct, different shapes and sizes of the air duct require the filter to be installed on different air ducts, which increases the production and installation costs of the filter and the difficulty of operation, making it more difficult to replace the filter. If the filter cannot be replaced in time, it may lead to technical problems such as reduced air filtration effect. Utility Model Content

[0005] The purpose of the utility model is to provide a warm pass filtering device to solve the technical problem in the prior art that due to the different shapes and sizes of air ducts, the filter needs to be installed for different air ducts, which increases the production and installation costs of the filter and the difficulty of operation, and may also lead to a reduction in the air filtration effect.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0026] like Figure 1-Figure 3 As shown, a warm pass filtering device comprises an air duct 1, the inner diameter of the air duct 1 is a ring structure, and a filtering device is arranged inside the air duct 1;

[0027] The filtering device comprises an annular mounting groove 2 and a filter plate 3, wherein the annular mounting groove 2 is arranged inside the air duct 1, and the inner diameter of the annular mounting groove 2 is larger than the inner diameter of the air duct 1, and a bracket 5 is arranged inside the annular mounting groove 2, wherein the bracket 5 is a semicircular arc plate, and the filter plate 3 is arranged inside the bracket 5, and the bracket 5 can position the filter plate 3, and a filter hole 30 is arranged on the filter plate 3, and the filter hole 30 is arranged obliquely, and an arc-shaped mounting opening 6 which is arranged in cooperation with the bracket 5 is arranged on the air duct 1, and a positioning bolt is detachably connected between the bracket 5 and the arc-shaped mounting opening 6, and the bracket 5 and the arc-shaped mounting opening 6 are connected by the positioning bolt;

[0028] The thickness of the bracket 5 is less than that of the air duct 1. The bracket 5 is provided with a positioning groove 50. The positioning groove 50 is a semicircular arc structure. The filter plate 3 is clamped in the positioning groove 50. That is, when the bracket 5 is installed in the arc-shaped installation opening 6, the outer wall of the filter plate 3 fits the annular installation groove 2 and the inner wall of the positioning groove 50, ensuring the stability of the position of the filter plate 3 and the state after installation.

[0029] An air guide structure is provided in the air duct 1; the air guide structure includes an air guide plate 7, which is arranged inside the air duct 1 and is semi-funnel-shaped. The air guide plate 7 is located on the side of the filter plate 3 close to the air inlet of the air duct 1, and an impurity retention gap 4 is provided between the side of the filter plate 3 close to the air inlet of the air duct 1 and the inner wall of the annular mounting groove 2.

[0030] The working principle of the utility model is as follows: the filter plate 3 is installed in the bracket 5, and the bracket 5 is used as a medium to facilitate the removal of the filter plate 3 on the air duct 1. Since the bracket 5 is a semicircular arc plate, when the bracket 5 is installed in the arc-shaped installation opening 6, the outer wall of the filter plate 3 fits the inner wall of the annular installation groove 2 and the positioning groove 50, ensuring the stability of the position of the filter plate 3 and the state after installation;

[0031] The airflow flows along the air duct 1. When it encounters the filter plate 3, the impurities in the airflow are intercepted by the filter plate 3. The intercepted impurities fall under the action of gravity until they fall on the impurity interception gap 4, thereby collecting the impurities. When the impurities need to be processed, the bracket 5 is removed from the air duct 1, thereby cleaning the impurities and the filter plate 3.

[0032] Then, the airflow is guided by the semi-funnel-shaped air guide plate 7, and the airflow is blown in an inclined state. The airflow is blown obliquely toward the filter plate 3. Under the action of the oblique airflow, the trapped impurities are prevented from hanging on the surface of the filter plate 3. After the oblique flow guidance, the airflow is blown toward the top of the annular mounting groove 2, and then guided along the inner surface of the annular mounting groove 2, so as to be gathered at the bottom of the filter plate 3, and then the impurities are gathered in the impurity retaining gap 4 at the bottom of the filter plate 3. The impurity retaining gap 4 is helpful for the storage of impurities.

[0033] The top height of the air guide plate 7 is between one-third and one-half of the filter plate 3, which helps the airflow guided by the air guide plate 7 to blow toward the filter plate 3 over a large range, and further helps the airflow to be discharged smoothly. The filter holes 30 arranged on the filter plate 3 are located above the top of the air guide plate 7, which helps impurities to be retained at the bottom of the filter plate 3. The filter holes 30 are inclined, tilted upward from one side of the filter plate 3 close to the air inlet of the air duct 1 to the other side. The inclined setting of the filter holes 30 helps the airflow guided by the air guide plate 7 to pass through the filter holes 30 and continue to be discharged forward.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
