AI Technical Summary
Existing circulating multi-stage filtration and recovery hydrocarbon solvent vacuum cleaning machines are prone to heating element burnout and vacuum pump oil deterioration when gas circulation is interrupted, making it impossible to maintain vacuum. Oil stains re-adhere to the workpiece, posing a risk of fire and personnel inhalation.
A circulating multi-stage filtration and recovery hydrocarbon solvent vacuum cleaning machine was designed. Through a multi-layer filtration system and closed-loop design, including a coarse filter, a fine filter, filter cotton, activated carbon, and filter plates, the solvent vapor is controlled in a closed loop, reducing contact with outside air, reducing vapor leakage and fire risk, and improving solvent purity through a porous structure.
Effective control of solvent vapor in a closed loop reduces vapor leakage and fire risk, improves solvent purity, ensures solvent recyclability, extends vacuum pump life, and prevents oil re-adhesion.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figures 1-4 This utility model provides a circulating multi-stage filtration and recovery hydrocarbon solvent vacuum cleaning machine, which includes a housing 1. An air pipe 5 is fixedly connected to the outside of the housing 1. A first coarse filter 9 is fixedly connected to the inside of the housing 1. A fine filter 10 is fixedly connected to the bottom of the first coarse filter 9. A second coarse filter 11 is fixedly connected to the bottom of the fine filter 10. Filter cotton 12 is fixedly connected to the inside of the housing 1.
[0025] Specifically, inside the housing 1, the hydrocarbon solvent containing oil, dust, and other impurities first comes into contact with the first coarse filter 9, directly filtering out larger solid particles or lumpy impurities, preventing rapid clogging of subsequent fine filtration components. The solvent that has passed through the initial filtration enters the fine filter 10, capturing micron-sized fine impurities and oil. This is a key step in improving solvent cleanliness and directly determines the final cleaning effect. A second coarse filter 11 is installed inside the housing 1. On the one hand, it can intercept fibers or debris detached from the fine filter 10, and on the other hand, it can block slightly larger impurities that have not been completely filtered, forming a double protection. Finally, the solvent flows through the filter cotton 12, where its porous structure adsorbs residual tiny oil stains, pigments, and odors, further improving solvent purity and ensuring that the recovered solvent can be recycled.
[0026] Port 2 is fixedly connected to the top of the box 1, and storage box 3 is slidably connected inside the box 1.
[0027] The storage box 3 has a handle 4 as its external fixed connection.
[0028] One end of the vent pipe 5 is fixedly connected to the first protective shell 6, and the fan 14 is rotatably connected inside the first protective shell 6.
[0029] The first protective shell 6 is internally fixedly connected to a ventilation plate 13, and the ventilation pipe 5 is externally fixedly connected to a second protective shell 7.
[0030] Specifically, the gas generated during the cleaning process of the housing 1 enters the ventilation pipe 5 through the fan 14 inside the first protective shell 6, and then enters the first filter plate 15 inside the second protective shell 7 for initial filtration.
[0031] The first filter plate 15 is fixedly connected inside the second protective shell 7.
[0032] The vent pipe 5 is externally fixedly connected to a third protective shell 8, and the third protective shell 8 is internally fixedly connected to activated carbon 16.
[0033] The third protective shell 8 has a second filter plate 17 fixedly connected inside.
[0034] Specifically, the gas enters the third protective shell 8 through the vent pipe 5, where the activated carbon 16 inside the third protective shell 8 adsorbs some harmful gases, and then undergoes secondary filtration through the second filter plate 17. Finally, the gas re-enters the box 1 through one end of the vent pipe 5.
[0035] Working principle: During the cleaning process of chamber 1, the gas generated enters the ventilation pipe 5 through the fan 14 inside the first protective shell 6, and then enters the first filter plate 15 inside the second protective shell 7 for initial filtration. It then enters the third protective shell 8 through the ventilation pipe 5, where activated carbon 16 adsorbs some harmful gases, and the gas undergoes secondary filtration through the second filter plate 17. Finally, it re-enters chamber 1 through one end of the ventilation pipe 5. This process keeps the solvent vapor inside the equipment in a closed loop, preventing excessive contact with outside air and reducing the amount of vapor leaking into the workshop environment. This reduces the risk of fire and personnel inhalation at the source. The chamber 1 contains oil, dust, and other contaminants. The hydrocarbon solvent containing impurities first comes into contact with the first coarse filter 9, directly filtering out larger solid particles or lumpy impurities, preventing rapid clogging of subsequent fine filtration components. The solvent that has passed through the initial filtration enters the fine filter 10, capturing micron-sized fine impurities and oil stains. This is a key step in improving solvent cleanliness and directly determines the final cleaning effect. A second coarse filter 11 is installed inside the housing 1. On the one hand, it can intercept fibers or debris detached from the fine filter 10, and on the other hand, it can block slightly larger impurities that have not been completely filtered, forming a double protection. Finally, the solvent flows through the filter cotton 12, where its porous structure adsorbs residual tiny oil stains, pigments, and odors, further improving solvent purity and ensuring that the recovered solvent can be recycled.
[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
