[0030] The following further elaborates on the present invention Figure 1 - Figure 6 in conjunction with the appended drawings.
[0031] The embodiment of the present invention discloses a residue recovery device for floor cleaner production and its filtration and regeneration process.
[0032] It should be noted that in the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the present invention.
[0033] Referring to Figures 1 - 6 , a residue recovery device for floor cleaner production, comprising: A recovery box 1, the interior of which is sequentially divided by partitions from right to left into an evaporation chamber 11, a slag fishing chamber 12, and a slag storage chamber 13, and different operations are completed in different partitions. It should be noted that the top of the evaporation chamber 11 is detachably connected with a box cover, which is omitted in the figure for the convenience of showing the internal structure. The top of the slag fishing chamber 12 is detachably connected with a cover plate 14. A strip-shaped through groove is opened on the top of the cover plate 14. A slag fishing mechanism is arranged in the slag fishing chamber 12. A traveling mechanism for controlling the movement of the slag fishing mechanism is arranged on the outer surface of the cover plate 14. The top of the cover plate 14 is fixedly communicated with a storage tank 141 communicated with the slag fishing chamber 12. A coagulant is stored in the storage tank 141. One side top of the cover plate 14 close to the slag storage chamber 13 is detachably connected with a hair dryer 15; The slag fishing mechanism includes a hollow rod 125, an air vent connecting rod 126, a bottom block 127, and a bottom net assembly 128. The hollow rod 125 is fixedly connected with the traveling mechanism. An air pump is arranged in the hollow rod 125. The air vent connecting rod 126 is coaxially and fixedly connected with the hollow rod 125, and a plurality of through holes are opened on the surface of the air vent connecting rod 126. The bottom block 127 is fixedly connected with one end of the air vent connecting rod 126. The bottom net assembly 128 is rotatably connected with the bottom block 127. A trigger assembly for controlling the operation of the hair dryer 15 is arranged on the traveling mechanism.
[0034] Specifically, when recovering residues, first add the coagulant into the storage tank 141 respectively. Transport the residues to the slag removal chamber 12 through a pipeline. After natural sedimentation for a period of time, add the coagulant in the storage tank 141 into the slag removal chamber 12. At this time, the traveling mechanism works to drive the hollow rod 125 to float up and down and move horizontally at the same time, driving the bottom screen assembly 128 to mix the liquid, accelerating the aggregation of suspended matter. After mixing for a period of time and then stopping, under the action of the coagulant, tiny bubbles adsorb light suspended matter (such as grease or low-density particles). Then, control the slag removal mechanism to move through the traveling mechanism, and scrape off the scum on the liquid surface. When the bottom screen assembly 128 completely extends out of the slag removal chamber 12 and enters the slag storage chamber 13, the trigger assembly is connected to the blower 15, and blows the scum into the slag storage chamber 13, replacing manual slag removal and improving the slag removal efficiency. After air flotation separation, transport the remaining liquid in the slag removal chamber 12 to the evaporation chamber 11 through a pipeline to carry out the recovery work of useful components.
[0035] Referring to Figure 1 and Figure 2 , specifically, in the embodiment of the present invention, the traveling mechanism includes a sliding table 121, a moving frame 122, a cylinder 123 and a connecting rod 124. The sliding table 121 is fixedly connected to the top end of the cover plate 14. The moving frame 122 is slidably connected to the sliding table 121. The cylinder 123 is installed on the moving frame 122. One end of the connecting rod 124 is coaxially and fixedly connected to the output shaft of the cylinder 123, and the other end is detachably connected to the hollow rod 125. The connecting rod 124 is located inside the strip-shaped through groove. The moving frame 122 is of a "C" shape structure, and its height is higher than the height of the storage tank 141 to ensure that the storage tank 141 will not interfere with the movement of the moving frame 122.
[0036] In the embodiment of the present invention, the horizontal movement of the moving frame 122 is controlled by the sliding table 121, and the up and down movement of the connecting rod 124 is controlled by the cylinder 123, thereby controlling the up and down and horizontal movement of the slag removal mechanism, and completing the corresponding operations according to specific process steps. The structure is simple and easy to operate, reducing the operation cost.
[0037] Referring to Figure 1 - Figure 4 , specifically, in the embodiment of the present invention, the trigger assembly includes a connecting ring 151 and a conductive block 152. An energizing slot is opened on the outer wall of the blower 15. The conductive block 152 is adapted to the energizing slot. The connecting ring 151 is detachably connected to the connecting rod 124, and the conductive block 152 is fixedly connected to the connecting ring 151.
[0038] In the embodiment of the present invention, during the process of removing scum, when the conductive block 152 is not connected to the energizing slot, the blower 15 is always in an open circuit state. When the conductive block 152 is inserted into the energizing slot, the internal circuit of the blower 15 forms a closed loop and starts to work, blowing off the scum.
[0039] Reference Figure 5 Specifically, in the embodiment of the present invention, the bottom net assembly 128 includes a filter screen 1281, a rotating rod 1282, a return spring 1283, and a frame 1284. The filter screen 1281 is disposed within the frame 1284. The frame 1284 is provided with a groove matching the shape of the bottom block 127. One end of the rotating rod 1282 is fixedly connected to the outer wall of the groove of the frame 1284, and the other end is rotatably connected to the outer wall of the bottom block 127. The return spring 1283 is sleeved outside the rotating rod 1282, and its two ends are respectively fixedly connected to the groove and the outer wall of the rotating rod 1282. The air outlet of the hair dryer 15 is obliquely downward. A baffle 131 is fixedly connected to the top end of the slag storage chamber 13. A pressing block 154 is movably connected to the inner wall of the slag storage chamber 13. The lowest point of the pressing block 154 is lower than the bottom net assembly 128.
[0040] In the embodiment of the present invention, the filter screen 1281 is used to catch the floating slag and separate the floating slag from the liquid. During the process of removing the floating slag, when the frame 1284 extends out of the slag fishing chamber 12, it abuts against the pressing block 154. Under the action of the pressing block 154, the frame 1284 tilts downward, which is more convenient for the floating slag to enter the slag storage chamber 13 for unified collection. The solid residues obtained by precipitation and air flotation can be resourcefully utilized by incineration for power generation or as building material additives. It should be noted that when the frame 1284 retracts, it loses the abutting action of the pressing block 154 and returns to the horizontal state under the action of the return spring 1283.
[0041] Reference Figure 2 Specifically, in the embodiment of the present invention, a plurality of brackets 111 are provided on the inner wall of the evaporation chamber 11 at different heights. The activated carbon net 112 is detachably connected to the brackets 111. The heating tube 113 is disposed at the bottom of the evaporation chamber 11 and is located on the bottom side of the activated carbon net 112.
[0042] In the embodiment of the present invention, when recovering the useful components, first, the activated carbon net 112 adsorbs the organic substances (such as spices, preservatives, etc.) in the residues. After adsorption saturation, the activated carbon net 112 is taken out and placed on the bracket 111 above the liquid level. At the same time, a collecting plate is placed on the bottom side of the activated carbon net 112. After heating the liquid, a concentrated liquid is obtained, and at the same time, the useful components on the activated carbon net 112 are regenerated and recovered by steam, improving the utilization rate of resources.
[0043] Reference Figure 4 Specifically, in the embodiment of the present invention, the top end of the storage tank 141 is detachably connected with a tank cover 142. A solenoid valve 144 is provided on the communication pipeline between the storage tank 141 and the slag fishing chamber 12.
[0044] In the embodiment of the present invention, the addition of the coagulant is controlled by the solenoid valve 144, and the tank cover 142 prevents foreign matters from entering the coagulant and contaminating the coagulant.
[0045] Specifically, a filtration and regeneration process for residues in the production of floor cleaners includes the following steps: Step 1: Pretreatment. Inject the residues from the production of floor cleaners into the slag removal chamber 12 through a pipeline. Add acid / alkali according to the acidity and alkalinity of the residues to optimize the coagulation efficiency and prevent equipment corrosion to ensure stable subsequent treatment. Step 2: Natural sedimentation and coagulation process. After balancing the residues, let them stand for a period of time for natural sedimentation, and then add polyaluminum chloride PAC or polyacrylamide PAM coagulant to promote the colloidal particles in the residues to aggregate into flocs. Step 3: Flotation separation. Work the air pump in the hollow rod 125 to pressurize the ventilation connecting rod 126, so that tiny bubbles are generated in the through holes of the ventilation connecting rod 126. The tiny bubbles adsorb light suspended solids, and the surface scum is recovered through the slag removal mechanism. Step 4: Concentrate recovery. Transport the liquid in the slag removal chamber 12 to the evaporation chamber 11 through a pipeline. The activated carbon net 112 adsorbs the organic matter in the residues. After adsorption saturation, take out the activated carbon net 112 and place it on the rack 111, which needs to be higher than the liquid level. The heating tube 113 is used for heating and concentration, and the useful components on the activated carbon net 112 can be regenerated and recovered by using steam.
[0046] Through the above steps, the removal rate of suspended solids ≥ 95% and the COD reduction rate ≥ 90% are achieved, and at the same time, more than 60% of the effective components are recovered for regeneration.
[0047] The above are all the preferred embodiments of the present invention. The protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
