Description

Technical Field

[0001] This utility model relates to the field of waste liquid recycling technology, specifically a waste liquid recycling device for dismantling scrapped motor vehicles. Background Technology

[0002] During the dismantling of automobiles, a large amount of waste fluid remains inside the vehicle, which needs to be extracted during the dismantling process.

[0003] In the prior art, Chinese utility model publication CN217103068U discloses a waste liquid extraction and discharge device for scrapped motor vehicles, including a storage tank for holding waste liquid. The storage tank has a drain pipe at its bottom and an inlet pipe and a gas control device at its top. The gas control device is used to control the gas pressure in the storage tank during extraction and discharge, and includes a vacuum pump and three sets of reversing valves. This utility model, through the cooperation of the three sets of reversing valves, can adjust the positive and negative gas pressure in the storage tank during extraction or discharge, achieving multiple uses in one machine to complete the transportation of waste liquid. This avoids the problem that current extraction and discharge equipment generally emphasizes extraction while neglecting discharge, resulting in cumbersome and inefficient discharge operations.

[0004] In the above technical solution, the waste liquid is directly drawn in through the inlet pipe. Since particulate impurities are inevitably mixed in with the waste liquid during the dismantling of motor vehicles, direct drawing in will easily draw the particulate impurities into the storage tank. Traditional equipment draws the waste liquid into the storage tank and then filters it to remove impurities. However, when the particles in the waste liquid are transported in the pipeline, they can easily cause scratches on the inner wall of the pipeline, reducing the service life of the pipeline. Utility Model Content

[0005] The purpose of this utility model is to provide a waste liquid recycling device for dismantling scrapped motor vehicles. By setting a suction head at the liquid inlet of the hose, the filter holes in the suction head are used to filter impurities of different particle sizes, thereby reducing the damage of impurities to the hose and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste liquid recovery device for dismantling scrapped motor vehicles, comprising:

[0007] Recycling bins;

[0008] A flexible hose connected to the top of the recycling bin, and a suction head connected to the other end of the hose, the flexible hose extending into the inner cavity of the recycling bin and connected to a filter cartridge, the inner cavity of the filter cartridge being provided with a filter cloth bag;

[0009] An air pump is fixed to the top of the recycling bin, and the air pump is connected to the recycling bin.

[0010] The suction head includes a fixed cylinder with filter holes of different diameters on its outer side. A movable cylinder is movably disposed inside the fixed cylinder, and a notch is provided on the outer side of the movable cylinder. A limiting component for adjusting the movable cylinder is provided inside the fixed cylinder to allow the notch to communicate with filter holes at different positions.

[0011] Preferably, the limiting component includes a fixed post fixed at the center of the bottom of the movable cylinder, a support spring sleeved on the outside of the fixed post, the two ends of the support spring being connected to the movable cylinder and the fixed cylinder respectively, positioning holes being opened around the top of the inner cavity of the fixed cylinder, and a positioning protrusion being fixed on the top of the movable cylinder, the positioning protrusion being engaged in the positioning hole.

[0012] Preferably, the top of the movable cylinder is connected to a column tube, and the end of the column tube away from the movable cylinder extends into the inner cavity of the hose.

[0013] Preferably, the end of the fixed column away from the movable cylinder passes through the fixed cylinder and is rotatably connected to a movable plate, and a limiting groove in a cross shape is provided at the bottom of the fixed cylinder.

[0014] Preferably, the filter holes are distributed in a sheet-like manner along the outer surface of the fixed cylinder, and the size of the notches is the same as the area covered by filter holes of different diameters.

[0015] Preferably, the top of the recycling bin has a threaded opening, and the filter cartridge is threadedly installed in the threaded opening.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses an air pump to draw air out of the recycling box, creating a negative pressure inside the box. It then connects to the outside via a hose, facilitating the extraction of waste liquid into the recycling box. Before entering the hose, the waste liquid passes through the filter holes on the fixed cylinder to filter impurities of different particle sizes, preventing impurities from being transported along the inner cavity of the hose and causing scratches to the inner wall of the hose, thus effectively extending the service life of the hose.

[0018] 2. By setting the size of the filter holes, this utility model allows for the selection of filter holes with different pore sizes when collecting different waste liquids, thus preventing impurities from clogging the outside of the suction head. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-5 The waste liquid recovery equipment for dismantling scrapped motor vehicles shown includes:

[0027] Recycling bin 1;

[0028] A flexible hose 2 is connected to the top of the recycling bin 1, and a suction head 3 is connected to the other end of the flexible hose 2. The flexible hose 2 passes through the inner cavity of the recycling bin 1 and is connected to a filter cylinder 4. A filter cloth bag is installed in the inner cavity of the filter cylinder 4.

[0029] An air pump 5 is fixed on the top of the recycling bin 1, and the air pump 5 is connected to the recycling bin 1.

[0030] The suction head 3 includes a fixed cylinder 31, with filter holes 32 of different diameters opened on the outer side of the fixed cylinder 31, and a movable cylinder 33 movably disposed in the inner cavity of the fixed cylinder 31. A notch 34 is opened on the outer side of the movable cylinder 33, and a limiting component for adjusting the movable cylinder 33 is provided in the inner cavity of the fixed cylinder 31 to make the notch 34 communicate with the filter holes 32 at different positions.

[0031] The air inside the recycling tank 1 is drawn out by the vacuum pump 5, creating a negative pressure inside the recycling tank 1. Then, it is connected to the outside through the hose 2, which facilitates the suction of waste liquid into the recycling tank 1. Before entering the hose 2, the waste liquid passes through the filter holes 32 on the fixed cylinder 31 to filter impurities of different particle sizes, so as to prevent impurities from being transported along the inner cavity of the hose 2 and causing scratches on the inner wall of the hose 2, thus effectively improving the service life of the hose 2.

[0032] Among them, such as Figure 4 As shown:

[0033] The limiting component includes a fixed post 6 fixed at the center of the bottom of the movable cylinder 33. A support spring 7 is sleeved on the outside of the fixed post 6. The two ends of the support spring 7 are connected to the movable cylinder 33 and the fixed cylinder 31 respectively. Positioning holes 8 are opened around the top of the inner cavity of the fixed cylinder 31. A positioning protrusion 9 is fixed on the top of the movable cylinder 33. The positioning protrusion 9 is engaged in the positioning hole 8. The support spring 7 supports the movable cylinder 33 upward. With the engagement of the positioning protrusion 9 and the positioning hole 8, the limiting between the movable cylinder 33 and the fixed cylinder 31 is achieved, so that the notch 34 on the movable cylinder 33 corresponds to the filter hole 32 in a certain area on the fixed cylinder 31.

[0034] Furthermore, such as Figure 4-5 As shown:

[0035] The top of the movable cylinder 33 is connected to the column tube 10. The end of the column tube 10 away from the movable cylinder 33 extends into the inner cavity of the hose 2. The column tube 10 facilitates the connection between the movable cylinder 33 and the hose 2, preventing waste liquid from directly entering the hose 2 from the gap between the fixed cylinder 31 and the movable cylinder 33, thus preventing the waste liquid from being filtered.

[0036] Preferred, such as Figure 2 and Figure 4 As shown:

[0037] The end of the fixed column 6 away from the movable cylinder 33 passes through the fixed cylinder 31 and is rotatably connected to the movable plate 11. The bottom of the fixed cylinder 31 has a limiting groove 12 arranged in a cross shape. By movably setting the movable plate 11 at one end of the fixed column 6, the movable cylinder 33 can be pulled downward, so that the positioning protrusion 9 can be moved out of the positioning hole 8, which facilitates the adjustment of the position of the notch 34 on the movable cylinder 33. At the same time, the limiting groove 12 is engaged with the movable plate 11, which further improves the stability between the movable cylinder 33 and the fixed cylinder 31.

[0038] It is worth noting that, such as Figure 2 and Figure 4 As shown:

[0039] The filter holes 32 are distributed in a sheet-like manner along the outer surface of the fixed cylinder 31. The size of the notch 34 is the same as the area covered by the filter holes 32 of different diameters. By describing the distribution of the filter hole 32 area, it is convenient to make the notch 34 on the movable cylinder 33 correspond to the filter hole 32 of the same diameter after rotating the movable cylinder 33, thereby avoiding the situation where impurities of different sizes enter the hose 2.

[0040] In a further preferred embodiment, such as Figure 3 As shown:

[0041] The top of the recycling bin 1 has a threaded opening 13, and the filter cylinder 4 is threaded into the threaded opening 13. The threaded opening 13 facilitates the disassembly and assembly of the filter cylinder 4, thereby cleaning the fine particles filtered by the filter bag inside the filter cylinder 4.

[0042] In practical use, the filter cartridge 4 is threaded into the threaded opening 13. Then, the air pump 5 is started to expel the air from the recovery tank 1, creating a negative pressure inside the recovery tank 1. Then, outside air flows into the recovery tank 1 along the hose 2. The hose 2 and the suction head 3 are placed in the waste liquid. The waste liquid then enters the recovery tank 1 through the air pressure difference along the suction head 3 and the hose 2. Before use, the size of the filter hole 32 can be adjusted according to the size of the impurity particles in the waste liquid. One end of the movable plate 11 is moved out of the limiting groove 12. The movable plate 11 is used to pull the fixed column 6 and the movable cylinder 33 downward within the fixed cylinder 31. Then, the positioning protrusion 9 moves out of the positioning hole 8, and the movable plate 11 is rotated. The fixed column 6 drives the movable cylinder 33 to rotate inside the fixed cylinder 31, so that the notch 34 on the movable cylinder 33 corresponds to the filter holes 32 at different positions on the fixed cylinder 31. After adjusting the size of the filter holes 32, the support spring 7 supports the movable cylinder 33 again, so that the positioning protrusion 9 is re-engaged with the positioning hole 8. At the same time, the movable plate 11 is engaged with the limiting groove 12 to limit and fix the movable cylinder 33. The waste liquid is filtered through the filter hole 32 and enters the filter cylinder 4 along the hose 2, and is filtered again by the filter bag to remove fine particulate impurities.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
