The condenser 13 is disposed between the vacuum pump 12 and the working tank 11, and condenses the solvent vapor pumped out of the working tank 11 by the vacuum pump 12.
The containing barrel 21 is used for containing a solvent for cleaning shoe materials, when the inside of the working tank 11 is vacuumized by the vacuum pump 12 to generate air pressure drop, the solvent in the inside can enter the working tank 11 in a controlled manner, and the solvent can be a high-purity hydrocarbon solvent or high-purity alcohols.
The heating unit 22 is used for heating the solvent in the accommodating barrel 21, in this embodiment, the solvent in the accommodating barrel 21 is heated by an electric heater, and the solvent is preheated to a suitable temperature below the boiling point, the temperature range is about 60-110 ℃, in this embodiment, the temperature is set to 60 ℃, and at this time, the solvent in the accommodating barrel 21 still remains in a liquid state.
The control valve 23 is assembled between the working tank 11 and the accommodating barrel 21, and is used for controlling the solvent in the accommodating barrel 21 to be conveyed to the working tank 11, when the vacuum pump 12 completes the first-stage vacuum-pumping operation, the control valve 23 is in an open state, so that a proper amount of the solvent in the accommodating barrel 21 enters the working tank 11 for cleaning operation, and when the vacuum pump 12 performs the second-stage vacuum-pumping operation, the control valve 23 is in a closed state.
The recycling pump 24 is connected to the working tank 11 for timely pumping out the condensed solvent in the working tank 11 and returning the solvent to the accommodating barrel 21.
The recycling tank 31 is connected to the condenser 13 and the accommodating tank 21, and is capable of receiving the solvent from the condenser 13 and transferring the solvent to the accommodating tank 21.
The filter 41 is connected to the working tank 11 to filter the air to be introduced into the working tank 11 from the outside, thereby equalizing the pressure inside the working tank 11.
The replenishment tank 51 is used to accommodate a new or regenerated solvent, so as to replenish the solvent to the accommodation barrel 21 at a proper time.
The dirty liquid pump 62 is disposed between the accommodating barrel 21 and the dirty liquid tank 61, and is used for conveying the dirty solvent in the accommodating barrel 21 to the dirty liquid tank 61.
The four on-off valves 71, 72, 73, 74 are respectively disposed between the condenser 13 and the working tank 11, between the working tank 11 and the filter 41, between the working tank 11 and the recovery pump 24, and between the recovery bucket 31 and the accommodating bucket 21, for opening or closing the flow path.
When the shoe material cleaning and drying device of the invention is used for cleaning shoe materials, firstly, the shoe materials to be cleaned are placed into the working tank 11, the heating unit 22 heats the solvent in the accommodating barrel 21 to a set temperature, the solvent is still in a liquid state at the moment, then the switch valve 71 is in an open state, the switch valves 72, 73 and 74 and the control valve 23 are set to be in a closed state, the vacuum pump 12 is operated to carry out first-stage vacuum pumping operation on the working tank 11, when the pressure in the working tank 11 is reduced to the set pressure, the control valve 23 is opened, the solvent in the accommodating barrel 21 is automatically conveyed into the working tank 11 under the action of atmospheric pressure, when the solvent enters the working tank 11, the solvent forms a steam state in the working tank 11 due to the decompression action, the steam-state solvent can carry out dead-corner-free cleaning operation on the shoe materials, and because the vacuum pump 12 is continuously operated, the decontaminated solvent vapor is pumped out of the working tank 11 and condensed to the recycling tank 31 through the condenser 13, and the solvent in the accommodating tank 21 continuously enters the working tank 11 for vapor cleaning until the cleaning process is completed.
After the cleaning operation is completed, the shoe material drying operation is performed, the vacuum pump 12 is still continuously operated to perform the second stage vacuum pumping operation on the working tank 11, at this time, the control valve 23 is closed, the solvent does not enter the working tank 11 any more, the solvent attached to the shoe material is evaporated by bumping due to further pressure reduction in the working tank 11 until the shoe material is completely dried, the solvent vapor pumped out by the vacuum pump 12 in the drying process is condensed to the recycling tank 31 by the condenser 13, the solvent in the recycling tank 31 is cooled and then is conveyed to the accommodating tank 21 by opening the switch valve 74 for reuse, after the cleaning and drying operation of the shoe material is completed, the vacuum pump 12 is closed and the switch valve 72 is opened, the external air is let to enter the working tank 11 through the filter 41 for pressure balance, the solvent remaining in the working tank 11 is conveyed to the accommodating tank 21 by opening the switch valve 73 through the recycling pump 24, the solvent in the accommodating tank 21 is pumped to the dirty liquid tank 61 by the dirty liquid pump 62 for regeneration treatment after the solvent is used for a period of When the solvent in the receiving tub 21 is insufficient, the replenishment tank 51 replenishes the new or regenerated solvent.
The shoe material cleaning and drying device of the invention vacuumizes the working tank 11 to generate pressure drop through the vacuum pump 12, so that the solvent enters the working tank 11 from a liquid state to form a steam state instantly, so that the solvent can clean the shoe material without dead angles, the solvent is preheated before entering the working tank 11, and the solvent is not required to be heated to the steam state as required by the conventional technology, so that the heating energy can be saved, in addition, when the shoe material drying operation is carried out, the drying operation can be carried out as long as the control valve 23 is closed, but the shoe material is required to be moved away from the cleaning liquid (or called solvent) by the conventional technology, so that the reduced pressure drying can be carried out, and the cost of the whole device is greatly increased by related mechanisms for moving the shoe material, therefore, the invention not only has the advantages of convenient operation and simple structure, but also can greatly reduce the whole manufacturing.
It should be noted that the process of cleaning and drying the shoe material can be further illustrated by a flow chart, referring to fig. 3, the first step is to put the shoe material into the working tank 11, the second step is to perform the first stage of vacuum pumping operation on the working tank 11 by the vacuum pump 12 to make the pressure inside the working tank 11 reach-700 mmHg, the third step is to open the control valve 23 to make the solvent in the holding barrel 21 enter the working tank 11 and form a vapor state, the fourth step is to close the control valve 23 and make the vacuum pump 12 perform the second stage vacuum-pumping operation to make the pressure in the working tank 11 reach-720 mmHg, at this time, the solvent attached to the shoe material is suddenly boiled and gasified to separate from the shoe material, so as to achieve the purpose of drying the shoe material, and the fifth step is to remove the vacuum state of the working tank 11 to take out the shoe material and recycle the residual solvent.
It is further supplemented to show that the shoe soles in the shoe manufacturing industry are often adhered with the release agent after injection molding, and the contamination of the release agent can cause poor bonding of the rear section, so that after injection molding, the shoe soles are cleaned and then subjected to bonding engineering to reduce the defective rate of bonding, and therefore, the cleaning and drying device is utilized to completely clean and dry the release agent so as to improve the yield of sole bonding; in addition, the solvent is gasified into a steam state at low temperature in the cleaning process, so that the material of the shoe material cannot change due to high temperature, such as secondary plasticization or secondary foaming, and the shoe material cleaning and drying device can also achieve the effect of preventing the material of the shoe material from changing.
