Description

Technical Field

[0001] The invention relates to the technical field of water-saving equipment, in particular to a water-saving cleaning system for a glass substrate. Background Art

[0002] Glass substrate is a thin glass sheet with an extremely flat surface, and is one of the key basic materials for the flat panel display industry. Glass substrate production requires fine polishing, cleaning, coating and glue leveling. The purpose of cleaning is to remove the powder adhering to the surface of the glass substrate during the fine polishing process. The wastewater generated during the cleaning process is generally regenerated and reused through a filtration system.

[0003] At present, there have been some studies on water-saving cleaning systems. For example, a Chinese utility model with publication number CN211004623U discloses an activated carbon sewage treatment device, whose structure includes a treatment box and an outlet pipe. The outlet pipe is installed on one side of the treatment box, the treatment box is provided with a water inlet chamber, the water inlet chamber is provided with a water inlet pipe, a through pipe, and a screw ring, the screw ring is installed around the purification chamber, the purification chamber is provided with a support plate, an activated carbon plate, a clean water chamber, a fixing plate, and a nut, a water volume controller is provided inside the water outlet pipe, the water volume controller is provided with a clean water outlet, a baffle, and a connecting rod, the baffle is a cylindrical plate, and the connecting rod is provided with a rotating block. For another example, a Chinese utility model with publication number CN208617417U discloses an activated carbon sewage treatment system, which includes a sewage inlet main pipe, an activated carbon new material tank, and an adsorption filter tank. A plurality of filter adsorbers with a self-flushing function are installed in the adsorption filter tank. The sewage inlet main pipe is connected to the filter adsorber through a water inlet branch. The adsorption filter tank is connected to an automatic feeding device that can automatically extract activated carbon from the filter adsorber. The main feeding pipe of the automatic feeding device is connected to a separation screen, and the separation screen is connected to a dry distillation activation furnace through a discharge pipe. The dry distillation activation furnace is connected to a regeneration tank through a discharge pipe. The activated carbon new material tank and the regeneration tank respectively feed the activated carbon into the filter adsorber through the automatic feeding device.

[0004] In the actual production process, the activated carbon particles near the water inlet of the filter are in full contact with the sewage, while the activated carbon particles near the water outlet of the filter are not in full contact with the sewage, resulting in a partial waste of activated carbon adsorption performance; in addition, in order to improve the adsorption effect of activated carbon, sulfonated coal is generally added to the activated carbon, taking advantage of the easy expansion of sulfonated coal when absorbing water to improve the pore development of activated carbon. However, this will cause the volume of activated carbon to expand after it comes into contact with water, and the piled activated carbons will squeeze each other, which will affect the full contact between activated carbon and sewage, and is not conducive to the activated carbon adsorbing powder in sewage.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2As shown, the present embodiment provides a water-saving cleaning system for a glass substrate, comprising a water tank 1 storing water, on which a water outlet pipe 2 and a water inlet pipe 3 are fixedly mounted by a bracket, and a water pump 4 connecting the water outlet pipe 2 and the water inlet pipe 3; the water outlet pipe 2 is in a horizontal state, and the water outlet of the water outlet pipe 2 is located at the bottom of the water outlet pipe 2, and there are multiple water outlets and they are evenly arranged in a direction parallel to the water outlet pipe 2; the bottom end of the water inlet pipe 3 is located below the water surface in the water tank 1, and a water storage device is installed in the bottom port of the water inlet pipe 3 The material barrel 5, the axis of the storage barrel 5 is in a horizontal state; the storage barrel 5 and the water inlet pipe 3 are threadedly matched, and a number of knobs 501 are evenly fixedly installed on the front end surface of the storage barrel 5 along its circumference. The operator drives the storage barrel 5 to rotate by pushing the knobs 501, thereby completing the disassembly and assembly of the storage barrel 5; a rotating drum 6 coaxial with it is rotatably installed in the storage barrel 5, and the front and rear end surfaces of the rotating drum 6 are both hollow; a rotating shaft 7 coaxial with it is installed on the front end surface of the rotating drum 6, and an impeller 8 is fixedly installed at one end of the rotating shaft 7. The activated carbon particles are stored in the rotating drum 6, and the activated carbon particles that expand after absorbing water occupy 3 / 4 of the volume of the rotating drum 6, that is, when the rotating drum 6 rotates, the activated carbon particles inside it will roll and move synchronously.

[0033] In the specific working process, the glass substrate to be cleaned is located below the water outlet pipe 2, and the water pump 4 draws water from the water tank 1 through the water inlet pipe 3 and delivers the water to the water outlet pipe 2. The water in the water outlet pipe 2 is sprayed downward from the water outlet to clean the glass substrate below it. The water in contact with the glass substrate takes away the powder attached to the glass substrate, that is, the water falling back into the water tank 1 is sewage with powder. After the sewage is sucked into the water inlet pipe 3, it passes through the drum 6. The activated carbon particles in the drum 6 contact the sewage and adsorb the powder in the sewage. In this way, the water entering the water pump 4 is water filtered and purified by the activated carbon; before being sucked into the water inlet pipe 3, the water acts on the impeller 8, generates thrust on the impeller 8, and makes the impeller 8, the shaft 7 and the drum 6 rotate synchronously. During the rotation of the drum 6, the activated carbon particles inside it also tumble and move, and the irregularly shaped activated carbon particles collide with each other, resulting in irregular displacement, thereby promoting the position exchange between the activated carbon particles near the front end of the drum 6 and the activated carbon particles near the rear end of the drum 6, making full use of the adsorption performance of the activated carbon particles at various locations in the drum 6. In addition, the collision between the activated carbon particles also promotes the separation of the activated carbon particles that are squeezed against each other due to expansion, and also improves the actual adsorption effect of the activated carbon.

[0034] like Figure 5As shown, the rotating drum 6 includes a cylinder body 601, on the outer circumferential surface of which a plurality of first balls 602 are rotatably mounted, and the first balls 602 are fitted with the inner circumferential surface of the storage barrel 5; a retaining ring 502 is fixedly mounted inside the storage barrel 5, and on the rear end surface of the rotating drum 6 a plurality of second balls 603 are rotatably mounted, and the second balls 603 are fitted with the retaining ring 502; in this way, the friction between the rotating drum 6 and the storage barrel 5 is greatly reduced when the rotating drum 6 rotates, thereby ensuring that the rotating drum 6 can rotate quickly.

[0035] like Figure 5 and Figure 6 As shown, a guide sleeve 604 is fixedly installed on the inner circumferential surface of the cylinder 601, and the number of guide sleeves 604 is two. A slide bar 605 is slidably installed on each guide sleeve 604 along the axial direction of the cylinder 601, and an annular push plate 606 is fixedly sleeved on the slide bar 605. A push rod 607 is slidably installed along the radial direction of the cylinder 601 at the position corresponding to each slide bar 605 on the circumferential surface of the cylinder 601, and an elastic member 608 is connected between the push rod 607 and the cylinder 601. The inner end surface of the push rod 607 is an inclined surface, and a first roller 609 is installed at one end of the slide rod 605 close to the push rod 607; a second roller 610 is installed at the outer end of the push rod 607; and a plurality of guide blocks 503 are evenly arranged along the circumferential direction at the position corresponding to the second roller 610 on the inner circumferential surface of the storage barrel 5.

[0036] Specifically, when the drum 6 rotates, each guide block 503 will periodically contact and push the second roller 610, and the second roller 610 will move synchronously with the push rod 607 toward the central axis of the drum 601, and the elastic member 608 will be stretched synchronously. During the movement of the push rod 607, the first roller 609, the slide bar 605 and the push plate 606 will be pushed synchronously toward the front end of the drum 6 (i.e. Figure 5 (right side in the middle), the push plate 606 pushes some of the activated carbon particles in contact with it to move forward during the movement toward the front end of the drum 6; as the drum 6 continues to rotate, when the second roller 610 separates from the guide block 503, the elastic member 608 recovers, so that the second roller 610 and the push rod 607 move synchronously away from the central axis of the cylinder 601 and reset relative to the cylinder 601. The push plate 606 drives the slide bar 605 and the first roller 609 to move to the left and reset under the action of the water flow, and pushes some of the activated carbon particles in contact with it to the left. This cycle is repeated, and the push plate 606 continuously pushes the activated carbon particles in the horizontal direction during the rotation of the drum 6, promoting the horizontal position switching of the activated carbon particles, which is conducive to fully utilizing the adsorption performance of the activated carbon particles in various places in the drum 6.

[0037] like Figure 6As shown, a plurality of protrusions 504 are evenly arranged on the inner circumferential surface of the storage barrel 5 between two adjacent guide blocks 503. When the second roller 610 passes over the protrusions 504, vibration will be generated, so that the push rod 607 will also vibrate along the radial direction of the rotating drum 6. The push rod 607 in the vibrating state drives the activated carbon particles in contact with it to vibrate as well, thereby promoting the activated carbon particles to stick together due to expansion and extrusion, and further utilizing the adsorption properties of the activated carbon particles in various places in the rotating drum 6.

[0038] like Figure 7 and Figure 8 As shown, the push plate 606 is provided with a plurality of circular through slots 611, and two rectangular rubber sheets 612 are fixedly installed on the surface of the push plate 606 facing the front end of the rotating drum 6 at the position corresponding to each through slot 611. The rubber sheets 612 will bend and deform under the action of external force, and will recover when the external force disappears. A limit strip 613 is fixedly installed in the through slot 611; specifically, when the push plate 606 moves toward the front end of the rotating drum 6 (i.e., toward Figure 5 The two rubber sheets 612 are fitted with the limit strip 613, and the edges of one side of the two rubber sheets 612 are fitted together, that is, the two rubber sheets 612 seal the through slot 611, and no activated carbon particles can pass through the through slot 611; when the push plate 606 moves toward the rear end of the drum 6 (that is, toward Figure 5 The rubber sheet 612 is deformed, and the activated carbon that is relatively displaced with the push plate 606 contacts the rubber sheet 612 and is squeezed and deformed. The rubber sheet 612 is bent, so that part of the activated carbon can pass through the through groove 611. In this way, during the horizontal reciprocating translation of the push plate 606, the activated carbon particles can be pushed from the back to the front more efficiently, thereby promoting the position conversion of the activated carbon in various places in the drum 6.

[0039] During the actual cleaning process, if the water flow is perpendicular to the glass substrate for cleaning, the water flow will exert a greater impact force on the glass substrate, causing slight deformation of the glass substrate, which is not conducive to the quality control of the glass substrate; if the water flow is parallel to the glass substrate, the cleaning effect cannot be guaranteed. Therefore, a more appropriate way is to let the water flow impact the glass substrate at an angle. In this way, it can avoid the water flow from exerting a greater impact force on the glass substrate and ensure the cleaning effect. Based on this, the present embodiment has the following design.

[0040] like Figure 1 , Figure 3 and Figure 4As shown, a guide rail 9 located below the water outlet pipe 2 and parallel to the water outlet pipe 2 is installed in the water tank 1; a plurality of slide seats 10 are slidably installed on the guide rail 9, a socket 11 is rotatably installed on the slide seat 10, a glass substrate is inserted into the socket 11, a torsion spring is arranged between the socket 11 and the slide seat 10, and the socket 11 and the glass substrate are kept in a vertical state in a normal state; the guide rail 9 and the inner wall of the water tank 1 are horizontally slidably matched in a direction perpendicular to the water outlet pipe 2; a first round rod 12 and a second round rod 13 parallel to the guide rail 9 are arranged in the water tank 1, the ends of the first round rod 12 and the second round rod 13 are jointly installed on a rod seat 14, and the rod seat 14 and the inner wall of the water tank 1 are horizontally slidably matched in a direction perpendicular to the water outlet pipe 2; the first round rod 12 and the second round rod 13 are located between the water outlet pipe 2 and the guide rail 9.

[0041] Specifically, before cleaning, the operator manually or by using a control arm in the prior art sequentially inserts each glass substrate into the corresponding socket 11, and then pushes each slide 10 to a predetermined position on the guide rail 9, such as Figure 1 and Fig. 9 As shown, at this time, all the glass substrates are located directly below the water outlet pipe 2; then the guide rail 9 is translated by external force to Fig.10 During this process, the slide 10, the socket 11 and the glass substrate are translated synchronously, and the glass substrate contacts the first round rod 12 and rotates relative to the guide rail 9 under the blockage of the first round rod 12 to reach Fig.10 In the state shown, the torsion spring is deformed synchronously; at this time, the glass substrate is in an inclined state. In this state, the water pump 4 is turned on, and the clean water in the water outlet pipe 2 is sprayed downward and contacts the inclined surface of the glass substrate, generating a force on the glass substrate, so that the glass substrate and the socket 11 continue to rotate, and the torsion spring continues to deform until the glass substrate rotates to Fig.11 In the state shown in FIG. 1 , the glass substrate is in contact with the second round rod 13, and the second round rod 13 supports the glass substrate; thus, the downward water flow impacts the glass substrate at an inclined angle, but the water flow does not start from the top of the glass substrate, so Fig.11 In this state, it is necessary to translate the rod seat 14 to the left through external force, so that the first round rod 12 and the second round rod 13 are translated to the left synchronously until the top of the glass substrate intersects with the water flow. During this process, the glass substrate is always subjected to the force of the water flow, and the second round rod 13 is always in contact with the glass substrate. In this way, during the cleaning process, the water flow always maintains an inclined state with the glass substrate, and can clean the entire surface of one side of the glass substrate. The second round rod 13 always supports the glass substrate, ensuring the stability of the glass substrate. After one side is cleaned, the rod seat 14 is first reset under the action of external force, and then the guide rail 9 is also reset under the action of external force. Each glass substrate and the socket 11 are also reset to the position under the action of the torsion spring. Fig. 9next, first turn off the water pump 4, and then follow the above steps, sequentially translate the guide rail 9 and the rod holder 14 in the opposite direction, and clean the other side of the glass substrate.

[0042] like Fig. 9 , Fig.10 and Fig.11 As shown, a first control arm 15 is fixedly mounted on the guide rail 9, and a second control arm 16 is fixedly mounted on the rod seat 14, and the ends of the first control arm 15 and the second control arm 16 both form cylindrical protrusions; a control board 17 is vertically slidably mounted on the inner wall of the water tank 1, and the control board 17 is electrically controlled, and a first guide groove 1701 cooperating with the first control arm 15 and a second guide groove 1702 cooperating with the second control arm 16 are provided on the control board 17; the middle part of the first guide groove 1701 is a symmetrical inclined section, and the top and bottom ends of the inclined section are respectively connected to the vertical section; the middle part of the second guide groove 1702 is a vertical section, and the top and bottom ends of the vertical section are respectively connected to the inclined section; Fig. 9 In the initial state shown, the protrusion at the end of the first control arm 15 is located in the middle of the first guide groove 1701, and the middle protrusion of the second control arm 16 is located in the middle of the second guide groove 1702; in this state, the guide rail 9 can be translated to the left to reach Fig.10 In the state shown, the protrusion at the end of the first control arm 15 reaches the top of the inclined section of the first guide groove 1701, and the middle protrusion of the second control arm 16 reaches the top of the vertical section of the second guide groove 1702; the control board 17 continues to move downward, the protrusion at the end of the first control arm 15 enters the vertical section of the first guide groove 1701, and the middle protrusion of the second control arm 16 enters the inclined section of the second guide groove 1702, that is, the guide rail 9 remains stationary, while the rod seat 14 moves horizontally to the left. After the cleaning of one side of the glass substrate is completed, the control board 17 returns to the top. Fig. 9 Then the control plate 17 moves, and the other side of the glass substrate is cleaned according to the above steps.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
