In contrast to the embodiment of fig. 11, the second purifying tank 40 of the embodiment of fig. 12 is disposed in parallel with the first purifying tank 10, that is, the dry-cleaning solvent is introduced into the second purifying tank 40 alternatively to the first purifying tank 10, which is also the role of disposing the first valve 15 and the second valve 42. The dry cleaning solvent then enters the liquid cleaning tank 80 from the respective outlets of the first or second purification tanks 10 and 40.

Referring to fig. 13, in an embodiment, based on the embodiment shown in fig. 12, other structures are not changed, and only the second purification tank 40 and the clean liquid tank 80 are connected to form a single tank, and the second purification tank 40 and the clean liquid tank 80 are separated only by the fine filter partition 81. With this arrangement, the connection pipe between the second purification tank 40 and the liquid purification tank 80 can be omitted, and the space inside the dry cleaning solvent purification apparatus 1 can be saved.

Referring to fig. 14, in one embodiment, a purified liquid tank 80 is disposed below the first purification tank 10, the first purification tank 10 is separated from an inner space of the purified liquid tank 80 by only a fine filtering partition 81, the fine filtering partition 81 has a plurality of plate holes 82 arranged in a matrix form and filled with fiber precision filter cores, a decoloring agent tank 90 is disposed outside the first purification tank 10, the decoloring agent tank 90 has a solvent inflow pipe 91, the solvent inflow pipe 91 extends from an upper portion of the decoloring agent tank 90 to a bottom portion of the decoloring agent tank 90, a spray head 92 is disposed at an outlet of the solvent inflow pipe 91, the decoloring agent tank 90 has a fifth solvent outlet 93 and a sixth solvent outlet 94, the fifth solvent outlet 93 is disposed at an upper portion of the decoloring agent tank 90, the sixth solvent outlet 94 is disposed at a bottom portion of the decoloring agent tank 90, the fifth solvent outlet 93 is communicated with the first solvent inlet 11, and the sixth solvent outlet 94 is communicated with a lower portion of the first purification tank 10.

Referring to fig. 15, in one or more embodiments, the circular shape includes a spherical shape and a cylindrical shape. In a modified embodiment, the first purification box 10 may be provided in a spherical shape, and a partition plate 13 is provided at a lower portion of the spherical first purification box 10, and the partition plate 13 is provided with a plurality of fine holes 14. The first solvent inlet 11 is disposed at the top of the first purification tank 10, the first open end 21 of the flexible filter bag 20 is connected to the first solvent inlet 11 by a quick coupling, the first body 23 naturally hangs down above the partition plate 13, and the portion of the first body 23 contacting the partition plate 13 is distributed on the partition plate 13 in a coiled manner. By "coiled manner" is meant that the first body 23 is spirally wound in a plurality of turns around a center of a circle on the plane of the partition 13, with a certain distance between adjacent turns to accelerate the flow rate of the dry-cleaning solvent. The partition 13 functions to support the flexible filter bag 20 and prevent the flexible filter bag 20 from drooping to the solvent outlet of the first purification tank 10 to block the solvent outlet. In order to facilitate the installation of the flexible filter bag 20, the spherical first purification box 10 can be divided into two halves in the middle part along the radial direction, and the two halves are sealed and spliced after the internal parts are installed. In further embodiments, the second purge tank 40 and the flexible decolorizing bag 50 may also be arranged in a circular and coiled shape like the first purge tank 10 and the flexible filter bag 20 of the above embodiments.

The first purification tank 10 and/or the second purification tank 40 and/or the liquid purification tank 80 are provided in a circular shape, and the strength of these tanks can be increased. So that the dry cleaning solvent supplied thereto may be strongly pressurized. Square tanks can withstand less pressure than round tanks, and if the pressure is too high, tank deformation occurs, for example flat tank walls can bulge or even rupture. As a result, if different shapes of the tanks are used, the pipe connections among the first purification tank 10, the second purification tank 40, and the liquid purification tank 80 may be different. In short, if a square box is adopted, the first purification box 10 and the second purification box 40 are connected in parallel as much as possible; if a circular tank is used, the first purification tank 10 and the second purification tank 40 are connected in series as much as possible. Of course, it is not necessary to connect the first and second decontamination boxes 10, 40 in this manner very strictly when certain special plumbing requirements are taken into account.

Referring to fig. 16, a modification is made on the basis of the embodiment of fig. 15, that is, a soft first solvent conduit 30 is provided in the flexible filter bag 20, and the first solvent conduit 30 is wound on the partition 13 as the flexible filter bag 20 is arranged in a coil shape. It will of course be appreciated that the flexible decolorizing bag 50 may be similarly configured, i.e., the flexible decolorizing bag 50 has the second solvent conduit 60 disposed therein and is configured in a flexible coiled configuration.

Referring to fig. 17, in one embodiment, the embodiment shown in fig. 10 is modified in that the first purge tank 10, the second purge tank 40, and the purge tank 80 are all provided in a circular shape. Other structural configurations are unchanged, and particularly, as in the embodiment shown in fig. 10, the second purification tank 40 and the liquid purification tank 80 are separately provided, and the bottom of the former is connected to the top of the latter through a pipe.

Referring to fig. 18, in one embodiment, the embodiment shown in fig. 17 is modified in that the second purification tank 40 and the liquid purification tank 80 are integrally provided, that is, the second purification tank 40 and the liquid purification tank 80 share a circular tank space, and the second purification tank 40 and the liquid purification tank 80 are separated by a fine filtering partition 81, the second purification tank 40 occupies a large space, and the liquid purification tank 80 occupies a small space. In addition, other structural configurations are unchanged, and particularly, as in the embodiment shown in fig. 17, the first and second purge tanks 10 and 40 are provided in a circular shape.

Referring to fig. 19, in one embodiment, some modifications are made to the embodiment shown in fig. 12, namely: the first purifying tank 10, the second purifying tank 40 and the liquid purifying tank 80 are arranged in a circular shape; the lower part of the first purifying tank 10 is provided with a first solvent outlet 16, and a first solvent inlet 11 is arranged at the top of the first purifying tank 10; the bottom of the second purifying tank 40 is provided with a second solvent outlet 43, and a second solvent inlet 41 is arranged at the top of the second purifying tank 40; the upper space of the liquid purifying tank 80 is provided with a third solvent inlet 83, and the lower space of the liquid purifying tank 80 is provided with a third solvent outlet 84; the first solvent outlet 16 is in sealed communication with the second solvent inlet 41, and the second solvent outlet 43 is in sealed communication with the third solvent inlet 83; a first valve 15 is provided in a pipe communicating with the first solvent inlet 11 outside the first purification tank 10, a second valve 42 is provided in a pipe communicating with the second solvent inlet 41 outside the second purification tank 40, and a seventh valve 17 is provided in a pipe communicating with the first solvent outlet 16 and the second solvent inlet 41. The pipe connection and the cleaning of the dry cleaning solvent in this embodiment are such that the dry cleaning solvent filtered in the first purifying tank 10 enters the second purifying tank 40 for further decolorization, enters the liquid purifying tank 80 for fine filtration after decolorization, enters the washing chamber 4 and other devices for washing, and then circulates to the first purifying tank 10 again for filtration and purification until the particulate contamination in the dry cleaning solvent is substantially completely filtered. Thereafter, the first valve 15 is closed, the second valve 42 is opened, and the decoloring purification is performed only in the second purification tank 40 without performing the filtering purification, through a plurality of cycles until the dry-cleaning solvent is completely decolored. It can be seen that the first and second purification boxes 10 and 40 can be connected in series at the beginning of the purification stage due to the high pressure resistance of the circular box, so that the number of cycles of the dry cleaning solvent can be reduced and the purification efficiency can be improved. However, the circular cabinet may have a smaller capacity than the rectangular cabinet, and the utilization of the inner space of the dry cleaning machine may be low. In the embodiment shown in fig. 12, the first and second purification tanks 10 and 40 are completely connected in parallel to the liquid purification tank 80, and when the particulate contaminants in the dry cleaning solvent are completely filtered in the first purification tank 10 through a plurality of cycles, the filtering cycle is stopped, and then the decoloring cycle is performed in the second purification tank 40. The number of cycles of the dry cleaning solvent may be larger, but the square box has a large capacity and a high utilization rate of the inner space of the dry cleaning machine.

In the embodiment shown in fig. 19, the second purification tank 40 is provided separately from the liquid purification tank 80, and the bottom of the former is connected to the top of the latter through a pipe.

Referring to fig. 20, in one embodiment, the second purifying tank 40 is integrally provided with a liquid purifying tank 80, which is different from the embodiment shown in fig. 19, and the integral arrangement can save the inner space of the dry cleaning machine and improve the space utilization. Specifically, the first purification tank 10 and the second purification tank 40 are arranged in a circular shape, and the second purification tank 40 and the liquid purification tank 80 share a circular tank body; the lower part of the first purifying tank 10 is provided with a first solvent outlet 16, and a first solvent inlet 11 is arranged at the top of the first purifying tank 10; a second solvent inlet 41 is provided at the top of the second purification tank 40; the lower space of the liquid purifying tank 80 is provided with a third solvent outlet 84; the first solvent outlet 16 is in sealed communication with the second solvent inlet 41, a first valve 15 is provided in a pipe communicating with the first solvent inlet 11 outside the first purification tank 10, a second valve 42 is provided in a pipe communicating with the second solvent inlet 41 outside the second purification tank 40, and a seventh valve 17 is provided in a pipe communicating with the first solvent outlet 16 and the second solvent inlet 42.
