Description

Technical Field

[0001] The utility model relates to the technical field of air handling units, in particular to a multi-stage purification device of a combined air handling unit. Background Art

[0002] Combined air handling unit is an integrated air handling equipment, which is assembled from multiple air handling functional sections. This equipment is suitable for air conditioning systems with a resistance greater than 100Pa, and can complete a variety of air handling functions, such as air mixing, flow balancing, filtration, cooling, heating, dehumidification, humidification, air supply and return, water spraying, noise reduction and heat recovery.

[0003] During the use of an air handling unit, it is inevitable to process the air entering the unit. In the process of air processing, most existing units use filters to filter the air. However, the effective filtration area of ​​the filter is small, and impurities on the surface are not easy to handle. The filter needs to be replaced frequently. Therefore, a multi-stage purification device for a combined air handling unit is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art that, in the process of air treatment, most of the air is filtered by means of a filter screen, and the effective filtering area of ​​the filter screen is small. At the same time, impurities on the surface are not easy to handle and the filter screen needs to be replaced frequently. A multi-stage purification device of a combined air handling unit is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A multi-stage purification device of a combined air handling unit, comprising an air inlet pipe installed on one side of the unit, wherein the top inner wall and the bottom inner wall of the air inlet pipe are fixedly connected with vertical plates, an inner frame is fixedly connected between the vertical plates, a fixing frame is fixedly connected between the inner walls around the inner frame, a clamping frame is arranged on one side of the fixing frame, a plurality of fixing bolts are plugged on one side of the clamping frame, the fixing bolts are all threadedly connected with the fixing frame, a non-woven bag is arranged between the fixing frame and the clamping frame, and the non-woven bag is fixed to one side of the fixing frame through the clamping frame;

[0007] The inner walls on both sides of the air inlet pipe are fixedly connected with guide rails, the two guide rails are slidably connected with sliding frames, the sliding frames are fixedly connected with filter screens, and the sliding frames pass through the top of the air inlet pipe.

[0008] As a further solution of the utility model, one side of the air inlet pipe is fixedly connected to an outer frame by bolts, and a plurality of blades are rotatably connected between inner walls on both sides of the outer frame.

[0009] As a further solution of the utility model, a protective frame is fixedly connected between the inner walls around the outer frame.

[0010] As a further solution of the utility model, two cleaning components for cleaning non-woven bags are provided between the inner walls on both sides of the air inlet duct, and the cleaning components include a driving shaft and a rubber rod. The driving shaft is rotatably connected between the inner walls on both sides of the air inlet duct, and the driving shaft is circumferentially connected to two rotating frames, and a torsion spring is fixedly connected between the rotating frames and the driving shafts, and a pressure roller is fixedly connected between the two rotating frames, the rubber rod is fixed to one side of one of the vertical plates for use in conjunction with the pressure roller, and the rubber rod in the other cleaning component is fixed to the bottom inner wall of the air inlet duct for use in conjunction with the other pressure roller.

[0011] As a further solution of the utility model, a motor is fixedly connected to the outer wall of one side of the air inlet duct, one end of the motor output shaft is fixed to one of the drive shafts, and the circumferences of the two drive shafts are fixedly connected with synchronous wheels, and the two synchronous wheels are transmission connected.

[0012] As a further solution of the utility model, two protruding connection blocks are fixedly connected to the top of the sliding frame.

[0013] In the present application, when in use, air enters the unit through the air inlet pipe, and the wind force is used to blow the blades to rotate, thereby allowing air to enter the air inlet pipe. The air then passes through the non-woven bag and undergoes preliminary filtration through the non-woven bag and the air. The space inside the non-woven bag is larger, the ventilation effect is better, and the number of replacement times is reduced. The air then enters the unit through the secondary filtration of the filter. When the air is introduced, the motor is started, and the motor drives one of the drive shafts to rotate, and the other drive shaft rotates at the same time under the action of the synchronous wheel. When the drive shaft rotates, the rotating frame is pushed to rotate by the torsion spring, and the rotating frame drives the pressure roller to rotate. The pressure roller stops rotating after contacting the rubber rod, and then the rotating frame is disengaged from the contact with the rubber rod under the continuous pressure of the torsion spring, and then impacts the non-woven bag, thereby causing the impurities in the non-woven bag to be concentrated at one end thereof, which is convenient for ventilation of the non-woven bag, and the filter can be taken out together with the sliding frame, thereby facilitating replacement of the filter.

[0014] Compared with the prior art, the utility model provides a multi-stage purification device of a combined air handling unit, which has the following beneficial effects:

[0015] In the utility model, the multi-stage purification device of the combined air handling unit is provided with a non-woven bag installed in the air inlet pipe. The bag-shaped non-woven bag can facilitate the air inlet pipe to enter, thereby reducing the number of times the filter element is replaced.

[0016] In the utility model, the multi-stage purification device of the combined air handling unit is provided with a pressure roller installed above and below the non-woven bag, so that after starting the motor, the pressure roller can be used to impact the non-woven bag, thereby facilitating the concentration of impurities inside the non-woven bag at one end of the non-woven bag, thereby improving the ventilation effect;

[0017] In the utility model, by installing a non-woven bag in the air inlet pipe, the bag-shaped non-woven bag can facilitate the air intake of the air inlet pipe, reduce the number of times the filter element is replaced, and at the same time, the pressure roller can impact the non-woven bag, thereby facilitating the concentration of impurities inside the non-woven bag at one end of the non-woven bag, thereby improving the ventilation effect.
