[0002] A DPF unit is a component of a diesel particulate filter, typically a cuboid. The diesel particulate filter is a crucial device for treating diesel vehicle exhaust fumes. Diesel exhaust not only has a strange odor but can also damage the respiratory tract and lungs, potentially causing emphysema, dizziness, nausea, and other symptoms, thus affecting human health.

[0003] DPF-loaded catalysts can improve particulate matter oxidation efficiency, enhance exhaust gas purification capabilities, extend service life, and optimize engine performance.

[0004] Currently, DPF unit catalyst loading technology has the following problems:

[0005] 1. Uneven catalyst loading;

[0006] 2. The catalyst support is easily damaged during the catalyst loading process;

[0007] 3. Incomplete loading of each surface of the DPF unit during catalyst loading;

[0008] Therefore, improvements are needed to address the above issues in order to meet market demands. Utility Model Content

[0013] In this utility model, the DPF unit catalyst loading device is characterized in that the electric drive is connected to the fixed plate through a rotating shaft.

[0014] The present invention relates to a DPF unit catalyst loading device, characterized in that a regulating valve is installed on the air inlet pipe.

[0015] The DPF unit catalyst loading device described in this utility model is characterized in that: the liquid inlet has a cap that can be removed and fixed by rotation.

[0016] In this utility model, the DPF unit catalyst loading device is characterized in that: the vertical atomizing structure nozzle is vertically downward, and the oblique atomizing structure nozzle forms an angle with the vertical direction and points towards the center of the loading box.

[0017] The present invention provides a DPF unit catalyst loading device, characterized in that the liquid storage tank is tightly connected to the loading tank via a partition.

[0018] In summary, the solution of this utility model is to fix the DPF unit by limiting the block, thereby reducing the collision between DPF units.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit the invention.

[0025] like Figure 1 As shown, a DPF unit catalyst loading device includes a loading tank 16, a storage tank 4, and a base 8. The upper part of the loading tank 16 is connected to the storage tank 4, the lower part is connected to the base 8, and the side is connected to a motor 6. A door 5 is installed on the front of the loading tank 16, and a locking handle 7 is installed on the door 5. An air inlet pipe 2 and a liquid inlet 3 are installed above the storage tank 4. The air inlet pipe 2 is equipped with a regulating valve 1, which can regulate the gas flow rate. The liquid inlet 3 has a cap that can be rotated off or fixed to achieve a sealing purpose.

[0026] like Figure 2 As shown, an oblique atomizing nozzle 9 and a vertical atomizing nozzle 10 are installed on the partition below the liquid storage tank 4; the oblique atomizing nozzle 9 is at a 45-degree angle to the vertical direction and points towards the middle of the load tank 16; the vertical atomizing nozzle 10 is vertically downward; it can spray the catalyst solution out in a mist.

[0027] like Figure 4 As shown, a fixing plate 12 is installed inside the load box 16 and is connected to the motor 6 via a rotating shaft 13; the fixing plate 12 has 5 square notches and 20 limiting blocks 11, which can fix a total of 5 DPF units; the limiting block 11 has a latch 15 and a locking tongue 14, and is connected to the limiting block 11 via a spring, which can control the extension and retraction of the locking tongue 14, thereby fixing the DPF unit.

[0028] The workflow of this utility model is as follows:

[0029] First, turn the lock handle 7 to open the door 5. Then, by pulling the latch 15, the latch 14 is retracted, and the DPF unit is placed into the notch. Then, the latch 14 is extended to fix the DPF unit. Next, the catalyst solution is poured in from the inlet 3, and the cap is tightened. Then, the air inlet pipe 2 is connected to the inert gas tank. After locking the door 5, the motor 6 is turned on. The motor 6 is driven by the rotating shaft 13 and the fixed plate 12, so that the fixed plate 12 rotates at a constant speed. At the same time, the speed of the fixed plate 12 can be controlled by adjusting the speed of the motor 6. The regulating valve 1 of the air inlet pipe 2 is opened to increase the pressure in the storage tank 4, so that the catalyst solution is sprayed out in the form of a mist from the oblique atomizing nozzle 9 and the vertical atomizing nozzle 10. After the loading is completed, the regulating valve 1 and the motor 6 are closed, the door 5 is opened, and the DPF unit loaded with catalyst is taken out.

[0030] In summary, this novel invention allows for the uniform loading of catalysts on all surfaces of the DPF unit without damaging it.

[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
