Description

Technical Field

[0001] The invention relates to the technical field of cleaning agent recycling, in particular to a cleaning agent waste liquid recycling device. Background Art

[0002] Cleaning agents are specially formulated products used for cleaning through the cleaning process. The main components are usually composed of surfactants, builders and additives. There are many types of cleaning agents. According to the type of dirt removed, they can be divided into heavy-duty cleaning agents and light-duty cleaning agents. After use, some cleaning agents on the market can be reused by filtering out debris, sand, etc. in the cleaning agent.

[0003] The existing cleaning agent impurity removal device uses an ordinary filter to initially filter the solid impurities in the cleaning agent, and then releases tiny bubbles in the cleaning water tank to entrain the tiny particle impurities in the cleaning agent to float on the liquid surface to form an impurity foam layer, and then uses a pure liquid tank to add a small amount of clean cleaning agent to the cleaning water tank to increase the liquid level in the cleaning water tank, so that the impurity foam layer overflows, thereby removing the tiny particle impurities in the cleaning agent; the impurity foam layer will be hung into the waste liquid tank by a scraper, and a basket is installed in the waste liquid tank, and a filter cloth is laid inside the basket, and the filter cloth is covered with a fine sand layer, and the impurity foam layer is re-filtered by the fine sand layer and the filter cloth. However, since the surfactant in the cleaning agent reduces the surface tension of water, the foam generated by the cleaning agent is not easily crushed by the contraction of the liquid surface, which results in the impurity foam layer entering the waste liquid tank being difficult to naturally disappear. These difficult-to-break foams will block the passage of the liquid through the fine sand layer and the filter cloth, reducing the filtration efficiency of the impurity foam layer. In the process of removing impurities from the cleaning agent in the impurity removal tank, since the filtration efficiency of the fine sand layer and the filter cloth on the impurity foam layer is low, the foam impurity layer in the waste liquid tank is easily reversed into the impurity removal tank, resulting in defects during use.

[0031] The scraping mechanism includes a reciprocating screw 4 and a sliding rod 5 respectively installed on the upper side of the impurity removal water tank 1. The reciprocating screw 4 is rotatably connected to the waste liquid tank 2 through a bearing. The connection between the sliding rod 5 and the waste liquid tank 2 is a fixed connection.

The limiting plate 8 can prevent the scraper 7 from being separated from the connecting seat 6.

[0034] The inside of the two waste liquid tanks 2 are both rotatably installed with stirring rods 28 through sealed bearings. The stirring rods 28 rotate inside the waste liquid tank 2, which is conducive to evenly mixing the defoaming agent and the waste liquid. The two stirring rods 28 are fixedly installed with synchronous wheels on the outside of the reciprocating screw 4 away from one end, and a synchronous belt is installed on the outside of the synchronous wheel.

[0035] The liquid adding mechanism includes a sleeve 14 fixedly mounted on the upper end of the waste liquid tank 2, a piston 15 that can move left and right is movably embedded inside the sleeve 14, a push rod 16 is fixedly embedded at the center of one side of the piston 15 close to the impurity removal tank 1, and the push rod 16 and the sleeve 14 are connected in a plug-in manner, and a stopper 17 is fixedly connected to one end of the push rod 16 away from the piston 15, and a spring 18 is movably sleeved on the outer side of the push rod 16, and the spring 18 can drive the piston 15 to move back and reset, and the two ends of the spring 18 are movably abutted against the sleeve 14 and the stopper 17 respectively.

[0036] A ball 19 is movably embedded in the center of the side of the block 17 away from the push rod 16, and the connection between the ball 19 and the extension plate 9 and the baffle 10 is rolling contact. A sewage pipe 30 connected to each other is fixedly installed at the lower end of the two waste liquid tanks 2, and one end of the sewage pipe 30 away from the waste liquid tank 2 is connected to the sediment filter. A liquid storage tank 29 is installed on the lower side of the sewage pipe 30, and a defoaming agent is stored in the liquid storage tank 29.

[0037] A conduit 20 that is interconnected is fixedly installed on the outer side of the sleeve 14, and a shunt pipe 21 that is interconnected is fixedly installed on the lower end of the conduit 20, and the two ends of the shunt pipe 21 are respectively located inside the impurity removal water tank 1 and the liquid storage tank 29. A conduit 22 is installed at the end of the sleeve 14 away from the impurity removal water tank 1. The conduit 22 is composed of a hard pipe and a corrugated pipe, and a one-way valve 23 is fixedly installed on both the conduit 1 20 and the conduit 22.

[0038] Working principle: the cleaning agent that has been initially filtered by an ordinary filter enters the impurity removal water tank 1, and tiny bubbles are released in the impurity removal water tank 1 to carry tiny particle impurities in the cleaning agent and float to the liquid surface to form an impurity foam layer. The driving motor 13 drives the reciprocating screw 4 to rotate, and the reciprocating screw 4 rotates through the connecting seat 6 to drive the scraper 7 to move back and forth in the impurity removal water tank 1. During the reciprocating movement of the scraper 7, the impurity foam layer will be pushed into the two waste liquid tanks 2. In this process, the pure liquid tank will add clean cleaning agent to the impurity removal water tank 1 to keep the liquid level in the impurity removal water tank 1 unchanged;

[0039] When the scraper 7 moves to the inclined guide plate 3, the inclined guide plate 3 will drive the scraper 7 to move upward until the scraper 7 moves into the waste liquid tank 2. When the scraper 7 moves into the waste liquid tank 2, the extension plate 9 and the baffle 10 will resist the ball 19 at the end of the block 17, and during the movement of the baffle 10, the baffle 10 drives the piston 15 to move inside the sleeve 14 through the block 17 and the push rod 16. During the movement, the piston 15 squeezes out the defoamer inside the sleeve 14, and the extruded defoamer enters the waste liquid tank 2. Under the action of the synchronous wheel and the synchronous belt, the stirring rod 28 rotates synchronously with the reciprocating screw 4, which is conducive to mixing the defoamer with the impurity foam layer in the waste liquid tank 2, thereby eliminating the foam in the impurity foam layer, which can prevent the foam that cannot be naturally eliminated from affecting the further filtration of the waste liquid, and can also prevent the foam from accumulating and flowing back into the impurity removal tank 1, effectively improving the filtration efficiency of the waste liquid;

[0040] When the scraper 7 moves back from the waste liquid tank 2 to the impurity removal tank 1, the piston 15 will move back and reset under the compression force of the spring 2 18. At this time, half of the defoaming agent and half of the clean detergent at the bottom of the impurity removal tank 1 will be sucked into the sleeve 14, which can dilute the defoaming agent to avoid excessive concentration of the defoaming agent in the waste liquid tank 2. When the liquid level in the waste liquid tank 2 reaches the preset value, the waste liquid in the waste liquid tank 2 is discharged into the sediment filter through the drain pipe 30 to further filter the waste liquid.

[0041] Example 2: Please refer to Figure 3 , Figure 5 This embodiment further explains Example 1, the spray assembly includes a hollow tube 24 installed on the upper side of the waste liquid tank 2, and the block 17 is fixedly sleeved on the outer side of the hollow tube 24, the conduit 22 is connected to the hollow tube 24 through the block 17, and a plurality of equidistantly distributed bent nozzles 25 are fixedly installed on the outer side of the hollow tube 24, and the end of the bent nozzle 25 away from the hollow tube 24 is oriented toward the scraper 7, which is conducive to spraying liquid to wash the scraper 7.

[0042] In the present embodiment: when the baffle 10 abuts against the ball 19 and the baffle 10 drives the hollow tube 24 to move, since the liquid outlet end of the bent nozzle 25 is directed toward the scraper 7, the diluted defoaming agent in the sleeve 14 is sprayed onto the scraper 7 through multiple bent nozzles 25, and the scraper 7 can be rinsed with the diluted defoaming agent, which can effectively remove foam impurities attached to the surface of the scraper 7, and prevent foam and impurities from attaching to the outside of the scraper 7 and being brought back into the impurity removal tank 1.

[0043] Example 3: Please refer to Figure 2 , Figure 4 This embodiment further explains Example 1. Baffles 26 are fixedly installed on the front and rear inner walls of the waste liquid tank 2, and a plurality of grooves 27 equidistantly distributed are opened on the upper end of the baffle 26, and the lowest part of the grooves 27 is flush with the highest part of the inclined guide plate 3. The width of the scraper 7 is smaller than the width of the grooves 27. The scraper 7 is in sliding contact with the baffle 26 through the plurality of grooves 27. The scraper 7 is in contact with the baffle 26 through the plurality of grooves 27, which is conducive to causing the scraper 7 to vibrate continuously.

[0044] In the present embodiment, since the lowest point of the groove 27 on the baffle 26 is flush with the highest point of the inclined guide plate 3, the scraper 7 will contact the baffle 26 after it detaches from the inclined guide plate 3. During the movement of the scraper 7 in the waste liquid tank 2, the scraper 7 slides in contact with the baffle 26 through the multiple grooves 27, and the drive of the compression elastic force of the spring 12 can make the scraper 7 move up and down and hit the baffle 26, so that the baffle 26 produces continuous vibration, which is conducive to the scraper 7 to shake off the diluted defoaming agent, and prevent the scraper 7 from bringing the defoaming agent into the de-impurity tank 1, which affects the impurity foam layer in the de-impurity tank 1.
