Description

Technical Field

[0001] This utility model relates to the field of recycling device technology, and more specifically, it relates to a recycling device for automotive urea solution. Background Technology

[0002] In existing technologies, urea solutions may experience crystallization and impurity precipitation during the recovery process. In particular, when the solution temperature changes or is stored for a long time, the uniformity and quality of the solution may be affected. Existing recovery devices usually lack an effective stirring mechanism, which may result in the urea and other components in the solution not being mixed evenly, affecting the use effect of the solution and the efficiency of the catalytic reduction reaction.

[0003] During the use of the recycling device, the filter plate is used to filter impurities, precipitates and particles in the urea solution to ensure that the recycled solution can be effectively reused. However, as the usage time increases, the impurities and deposits on the filter plate gradually increase, the filtration effect may decrease or even become blocked, thus affecting the efficiency of the entire recycling system and the quality of the urea solution.

[0004] In urea solution recovery devices, the treatment tank is usually used to store and process the recovered urea solution. However, after long-term use, dirt, residues or crystals may accumulate inside the treatment tank. If these substances are not cleaned in time, they may affect the quality of the solution and the efficiency of the system. Existing devices often do not have an effective cleaning water circulation system, and the cleaning water can only be cleaned manually or in a single cleaning cycle, which wastes water resources.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a device for recovering automotive urea solution, which has the following advantages:

[0018] 1. The processing component plays a core role in the entire urea solution recovery system. The combination of components such as the fixed base, processing cylinder, motor, and stirring rod enables the solution to be effectively mixed and processed. The motor drives the stirring rod to rotate, which in turn drives the spiral blades on the connecting plate and the rotating blades on the stirring rod, thereby ensuring that the solution in the processing cylinder is fully stirred and avoiding uneven solution composition. Especially when urea solution is mixed with other additives, it can ensure the uniformity of the solution and improve the recovery effect.

[0019] 2. The filtration assembly in this recovery device is responsible for removing impurities and precipitates from the urea solution, ensuring that the recovered solution maintains high quality, thereby effectively supporting the subsequent reuse of the urea solution. The discharge pipe, filter box, filter plate and other components work closely together. The valve installed on the discharge pipe can precisely control the flow direction of the solution, ensuring that the solution can effectively remove impurities when passing through the filter box.

[0020] 3. The design of the circulation component solves the problems of cleaning the treatment cylinder and circulating water. Through the circulation pipe, pump body and inclined plate installed between the treatment cylinder and the filter box, the water source can be circulated efficiently, thereby realizing automatic cleaning of the inside of the treatment cylinder. When the treatment cylinder needs to be cleaned, the water source is introduced into the treatment cylinder through the pump body, and the cleaning fluid can flow smoothly and clean all key components.

[0031] Please see Figures 1-6 A device for recovering automotive urea solution includes a support frame 1, on which a processing assembly is mounted. The processing assembly includes a fixed base 2, a processing cylinder 3, a motor 4, a stirring rod 5, and a connecting plate 6.

A filter assembly is mounted at the bottom of the processing cylinder 3, the filter assembly includes a discharge pipe 7, a filter box 8, and a feed hopper 9. The discharge pipe 7 is mounted at the bottom of the processing cylinder 3 and has a valve. The filter box 8 is located at the bottom of the discharge pipe 7, and the feed hopper 9 is mounted on the filter box 8. The discharge pipe 7 and the feed hopper 9 are aligned.

[0032] A spiral blade 10 is connected to the connecting plate 6.

[0033] Rotating blades 11 are evenly installed on the stirring rod 5.

[0034] A filter plate 12 is slidably connected to the filter box 8, and a fixing plate 13 is fixedly installed on the filter box 8. An insertion rod 14 is slidably connected to the fixing plate 13.

[0035] A movable plate 15 is connected to the top of the insertion rod 14. A handle 16 is installed on the movable plate 15. A spring 17 is sleeved on the insertion rod 14. The two ends of the spring 17 are connected to the movable plate 15 and the fixed plate 13. The insertion rod 14 passes through the fixed plate 13 and is inserted into the filter plate 12. A collection box 27 is installed on one side of the filter box 8.

[0036] In this embodiment, during use, the rotating cover 26 is rotated open along the feed hopper 25, allowing the solution or additives to be injected into the processing cylinder 3. Then, the motor 4 is started, causing the stirring rod 5 at the output end to rotate. During rotation, the connecting plate 6 on the rod drives the spiral blades 10 to promote mixing of the solution in the processing cylinder 3. The rotating blades 11 on the rod fully complete the mixing process. After the operation is complete, the valve on the discharge pipe 7 is controlled, allowing the solution to flow into the feed hopper 9 on the filter box 8, and finally into the filter box 8, thus flowing into the filter. The filter plate 12 is used to filter the solution. When the filter plate 12 needs to be removed for cleaning, the handle 16 is used to move the movable plate 15. During the movement, the insertion rod 14 slides along the filter plate 12 and the fixed plate 13, stretching the spring 17. After the insertion rod 14 is removed from the filter plate 12, the filtration process of the filter plate 12 is released. At this time, the filter plate 12 can be slid out along the filter box 8 for subsequent processing. After the processing is completed, the above operation is repeated to fix it.

[0037] Please see Figure 3-5 As an embodiment of a recycling device for automotive urea solution, the filter box 8 is provided with a recycling component, which includes a recycling pipe 18, a pump body 19 and an inclined plate 20.

[0038] A climbing ladder 21 is installed on the side end of the processing cylinder 3, a support seat 22 is installed at the bottom of the support frame 1, and a reinforcing rib 23 is installed on the support frame 1.

[0039] A protective railing 24 is installed on the processing cylinder 3, and a feeding hopper 25 is installed at the bottom of the processing cylinder 3. A rotating cover 26 is rotatably connected to the feeding hopper 25.

[0040] More specifically, during use, the filtered solution flows into the collection tank along the inclined plate 20 in the filter box 8, thereby processing and collecting the filtered urea solution. When it is necessary to clean the inside of the treatment cylinder 3, water is injected into the collection tank 27, and the pump 19 in the circulation pipe 18 is started to introduce water into the treatment cylinder 3 to clean the treatment cylinder 3. Various components are used in conjunction to promote the circulation of water.

[0041] In summary, during the use or operation of the entire equipment: During use, the rotating cover 26 is opened along the feed hopper 25, allowing the solution or additives to be injected into the processing cylinder 3. Then, the motor 4 is started, causing the stirring rod 5 at the output end to rotate. During rotation, the connecting plate 6 on the rod drives the spiral blades 10 to promote mixing of the solution in the processing cylinder 3. The rotating blades 11 on the rod further complete the mixing process. After the operation is complete, the valve on the discharge pipe 7 is controlled, allowing the solution to flow along the discharge pipe 7 into the feed hopper 9 on the filter box 8, and finally into the filter box 8, thus... The solution flows into the filter plate 12, which filters the solution. When the filter plate 12 needs to be removed for cleaning, the handle 16 moves the movable plate 15. During this movement, the insertion rod 14 slides along the filter plate 12 and the fixed plate 13, stretching the spring 17. After the insertion rod 14 is removed from the filter plate 12, the filtration process is released, and the filter plate 12 can be slid out of the filter box 8 for subsequent processing. After the processing is completed, the above operation is repeated to fix the filter plate.

[0042] During use, the filtered solution flows into the collection tank along the inclined plate 20 in the filter box 8, thereby processing and collecting the filtered urea solution. When it is necessary to clean the inside of the treatment cylinder 3, water is injected into the collection tank 27, and the pump 19 in the circulation pipe 18 is started to introduce water into the treatment cylinder 3 to clean the treatment cylinder 3. Various components are used in conjunction to promote the circulation of water.
