[0015] 1. The utility model reduces heat loss by adding a pipeline diversion device, adding a pipeline electric heater, and shortening the distance of the ventilation pipe. At the same time, a flexible connection air duct is added at the end of the electric heater and directly installed at the heating part of the required area, so that the temperature required by the special coating process can be achieved and the coating room ventilation can be completed. The modified combined air handling unit is suitable for heating in specific areas. Compared with the overall steam heat exchange device, it consumes less energy, heats faster, and is safer and more reliable.

[0016] When the pressure difference indicator or the pressure difference alarm prompts that the primary filter section needs to be cleaned, the pressure plate can be pressed to drive the vertical rod to move vertically downward. At this time, the sliding cooperation between the slide plate and the slide rod and the hinged action between the slide plate and the vertical rod and the connecting rod can be used to push the two sets of slide plates to move back to each other, thereby compressing the spring. At the same time, the hinged action between the vertical rod and the cross rod and the connecting rod can be used to push the cross rod to move toward the inside of the hollow tube when the vertical rod moves vertically downward, and the cooperation of the ball and the spiral groove can be used to drive the hollow tube to rotate. The rotation of the hollow tube drives the scraper to move in a circular motion, thereby cleaning the surface of the primary filter section. The operation is simple, convenient and fast, and the troublesome problems caused by frequent manual disassembly of the primary filter section are avoided. When the pressure plate is released, the vertical rod will automatically reset itself by utilizing the rebound effect of the spring. At this time, the scraper will also reverse to achieve reset, thereby performing secondary cleaning on the surface of the primary filter section, thereby improving the cleaning effect of the primary filter section.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Embodiment 1:

[0026] Please combine Figure 1-5 The combined air handling unit of this embodiment comprises:

[0027] The chassis 1 has a fresh air section 2, a fan section 3, a flow equalizing section 4, a filter section 5, a heating section 6 and an air supply section 7 arranged from left to right in the interior of the chassis 1. The fresh air section 2 includes an air inlet duct 21, and the air inlet duct 21 is fixedly connected to the left side of the chassis 1. The fan section 3 includes a double-inlet multi-wing centrifugal fan 31 fixedly connected to the inside of the chassis 1, and adopts differential pressure frequency conversion control. When the special area needs to dry and heat the air, the heat is converted through the air duct guide plate and the guide valve through the electric heater 61 to achieve the purpose of drying the air, which is suitable for the coating requirements of special parts. The flow equalizing section 4 includes a flow equalizing plate 41 arranged near the air outlet of the fan section 3. The flow equalizing plate 41 can evenly guide the airflow to each position of the flow equalizing section 4, thereby The airflow driven by the fan 31 is evenly distributed to prevent the airflow from being concentrated on a certain part of the flow-equalizing section 4 to avoid the generation of noise. The filter section 5 is divided into a primary filter section 51 and a medium filter section 52. The primary filter section 51 is composed of non-woven paint mist cotton and a frame of aluminum alloy material arranged on the outside thereof. The primary filter section 51 is fixedly connected with a pressure difference indicator or a pressure difference alarm at an external position corresponding to the chassis 1, so as to facilitate cleaning according to the prompt. The medium filter section 52 is composed of a medium filter and a frame of aluminum alloy material arranged on the outside thereof. The medium filter section 52 adopts a pull-out plate structure design, which is convenient for timely replacement. The air supply section 7 includes an air outlet duct 71, and the air outlet duct 71 is fixedly connected to the top right side of the chassis 1;

[0028] The cleaning assembly includes a vertical rod 101, which is vertically arranged inside the chassis 1. The top of the vertical rod 101 extends to the outside of the chassis 1 and is movably connected to the chassis 1. The top of the vertical rod 101 is fixedly connected to a pressure plate 102. The bottom of the inner cavity of the chassis 1 is symmetrically fixedly connected to a slide bar 103 through a connecting seat. The outside of the slide bar 103 is symmetrically slidably connected to a slide plate 104. A connecting rod 105 is hinged between the slide plate 104 and the vertical rod 101 through a hinge. A spring 106 is symmetrically sleeved on the outside of the slide bar 103. One side of the filter section 5 is symmetrically rotatably connected to a hollow tube 107 through a bracket, one end of the hollow tube 107 is fixedly connected to a scraper 108 on the outside, the inside of the hollow tube 107 is movably connected to a cross bar 109, a connecting rod 110 is hinged between the cross bar 109 and the vertical bar 101 through a hinge, a T-shaped connector is provided inside the hollow tube 107 and the T-shaped connector is fixedly connected to one end of the cross bar 109, a ball 111 is symmetrically movably connected to the T-shaped connector, and a spiral groove 112 is provided on the inner wall of the hollow tube 107 corresponding to the position of the ball 111.

[0029] The implementation principle of the combined air handling unit in the embodiment of the present application is as follows: the double-inlet multi-blade centrifugal fan 31 can suck fresh air through the air inlet pipe 21 and discharge it into the flow equalizing section 4, and after the airflow is equalized by the flow equalizing plate 41, it is filtered through the primary filter section 51 and the medium-efficiency filter section 52, and finally discharged through the air outlet pipe 71 to realize the ventilation of the coating workshop. When the pressure difference indicator or the pressure difference alarm prompts that the primary filter section 51 needs to be cleaned, the pressure plate 102 is pressed to drive the vertical rod 101 to move vertically downward. At this time, the sliding cooperation between the slide plate 104 and the slide rod 103 and the hinged effect between the slide plate 104 and the vertical rod 101 and the connecting rod 105 can be used to push the two groups of slide plates 104 to move back to back, so that the spring 106 can be compressed. The hinged connection between the rod 101 and the cross bar 109 and the connecting rod 110 enables the vertical rod 101 to push the cross bar 109 to move into the hollow tube 107 when it moves vertically downward. The cooperation between the ball 111 and the spiral groove 112 can drive the hollow tube 107 to rotate. The rotation of the hollow tube 107 drives the scraper 108 to move in a circular motion, so that the surface of the primary filter segment 51 can be cleaned. The operation is simple, convenient and fast, and the troublesome problems caused by frequent manual disassembly of the primary filter segment 51 are avoided. When the pressure plate 102 is released, the vertical rod 101 is automatically reset by the rebound effect of the spring 106. At this time, the scraper 108 will also reverse to achieve reset, so that the surface of the primary filter segment 51 can be cleaned for a second time, thereby improving the cleaning effect of the primary filter segment 51.

By starting the combined unit, three operation modes are selected, one of which is to supply air to the painting workshop, the second is to replace the 50°C warm air through the steam coil in winter, and the third is to replace the 50°C warm air through the unit electric heater 61 through the air duct guide plate and the air volume guide valve under special construction conditions. The three operation modes meet the process requirements of the painting process. One unit has multiple operation modes, which is simple to operate and energy-saving.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
