Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and specifically relates to a self-operating sewage cleaning device and a sewage cleaning method for a laboratory wastewater collection tank. Background Art

[0002] The laboratory wastewater collection tank is the core pretreatment unit of the laboratory wastewater treatment system, mainly used for centrally storing and preliminarily adjusting various experimental wastewaters to ensure the stability and safety of subsequent treatment processes. As the initial link of the system, the collection tank is responsible for receiving the mixed wastewater containing chemical reagents, biological pollutants (such as pathogenic microorganisms), heavy metal ions, and suspended solids generated in the laboratory. Its design needs to meet corrosion resistance (such as using fiberglass, stainless steel, or polyethylene materials) and sealing performance to prevent the volatilization or leakage of toxic and harmful substances and cause secondary pollution.

[0003] The wastewater in the laboratory wastewater collection tank is generally cleaned after being collected to a certain extent. The current cleaning methods are all to introduce the wastewater into the cleaning device for cleaning after the collection tank is full. This treatment method has low treatment efficiency and cannot achieve regular self-operation and automatic cleaning operation, affecting the overall use efficiency.

[0004] At the same time, during the sewage cleaning process of the cleaning device, external power is required to drive the operation of the cleaning device, and only sewage and solids can be separated during the entire cleaning process. However, the entire cleaning process occurs externally, and a large amount of solids still remain in the water storage part of the device, which cannot be effectively captured, affecting the cleaning quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a self-operating sewage cleaning device and a sewage cleaning method for a laboratory wastewater collection tank to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: An automatic self-operated sewage cleaning device for a laboratory wastewater collection tank, comprising a water storage tank. A medicine injection component is fixedly installed at a position near the top on the left side of the water storage tank. A water inlet pipe is fixedly communicated with the position near the bottom on the left side of the water storage tank. The other end of the water inlet pipe is communicated with the drainage end of the wastewater collection tank. The water storage tank is used for collecting wastewater. An extension guide rail is fixedly installed on the right side of the water storage tank. A liquid discharge component is movably clamped at the bottom end of the extension guide rail. A drain pipe is fixedly communicated with the position near the top on the right side of the water storage tank. A booster pump is built into the drain pipe. A linkage component is fixedly installed at a position near the top on the left side of the liquid discharge component. A through hole is opened in the middle of the top end of the water storage tank. The bottom end of the linkage component passes through the through hole and is located inside the water storage tank. A main shaft is movably installed in the middle of the water storage tank. The right end of the main shaft passes through the right end of the water storage tank and is fixedly connected with a transmission shaft. When the liquid discharge component is at the leftmost position, the left side of the liquid discharge component is fixedly sleeved with the transmission shaft, and the front end of the liquid discharge component is communicated with the drain pipe. Flocculation rods are fixedly installed at equal intervals on the outer side of the main shaft and are located inside the water storage tank.

[0007] Before cleaning the wastewater, the water inlet pipe can be communicated with the output end of the wastewater collection tank. The wastewater generated in the laboratory can enter the inside of the water storage tank through the water inlet pipe. As the wastewater enters, the liquid level of the wastewater inside the water storage tank rises accordingly.

[0008] As a further technical solution of the present invention, the linkage component includes a movable frame. An extension rod is fixedly installed at the top end of the movable frame and is located directly below the medicine injection component. An extension column is fixedly installed at the bottom end of the movable frame. The bottom end of the extension column passes through the bottom end of the through hole and is fixedly installed with a floating plate located inside the water storage tank.

[0009] As a further technical solution of the present invention, a first fixed seat is fixedly installed on the right side of the movable frame. One end of the first fixed seat away from the movable frame is movably connected with a connecting rod through a rotating shaft. One end of the connecting rod away from the first fixed seat is movably connected with a second fixed seat through a rotating shaft. The other end of the second fixed seat is connected to the liquid discharge component.

[0010] As the liquid level of the wastewater rises, the buoyancy received by the floating plate located inside the water storage tank increases, driving the floating plate to move upward. At this time, the extension column moves upward accordingly until the movable frame rises to the highest point position. At this time, the extension rod rises to the highest point. When the movable frame rises, it can drive the connecting rod to deflect obliquely upward and apply a leftward pulling force to the liquid discharge tank.

[0011] As a further technical solution of the present invention, a guiding block is fixedly installed at the top end of the liquid discharge tank. The liquid discharge tank is movably clamped with the extended guide rail through the guiding block. The liquid discharge tank is displaced left and right relative to the extended guide rail. The second fixed seat is connected to the left side of the liquid discharge tank.

[0012] As a further technical solution of the present invention, a receiving pipe is fixedly communicated at a position near the top end on the front surface of the liquid discharge tank. A sealing plate is fixedly installed on the front surface of the receiving pipe. A discharge pipe is fixedly communicated at a position near the bottom end on the back surface of the liquid discharge tank. A filter screen linkage assembly is fixedly installed at the rear end of the discharge pipe.

[0013] As a further technical solution of the present invention, a power shaft is movably installed in the middle of the liquid discharge tank. An impeller located inside the liquid discharge tank is fixedly sleeved on the outer side surface of the power shaft. The left side of the power shaft penetrates through the left side of the liquid discharge tank and is fixedly connected with a transmission sleeve.

[0014] As a further technical solution of the present invention, when the liquid discharge tank is located at the leftmost side, the transmission sleeve is movably sleeved with the transmission shaft, and the receiving pipe and the drain pipe are correspondingly arranged and communicated with each other.

[0015] When the liquid discharge tank is subjected to a pulling force towards the left side, at this time, the liquid discharge tank can be displaced towards the left side under the guiding action of the guiding block and the extended guide rail until the liquid discharge tank moves to the leftmost side. When the liquid discharge tank does not move to the leftmost side, at this time, the sealing plate can block the output end of the drain pipe. When the liquid discharge tank moves to the leftmost side, at this time, the drain pipe can correspond to the receiving pipe. The waste water inside the water storage tank can enter the inside of the receiving pipe through the drain pipe, and after passing through the liquid discharge tank, it is discharged through the discharge pipe and the filtering of the filter screen linkage assembly, completing the automatic cleaning process.

[0016] By utilizing the buoyancy provided by the continuously rising waste water inside the water storage tank, and using the cooperation between the linkage assembly and the liquid discharge assembly to convert the upward acting force into a left-right acting force, automatically driving the displacement of the liquid discharge assembly, and automatically completing the process of discharging the waste water through the liquid discharge assembly. The whole process can be automatically completed, and at the same time, relying on the buoyancy and water level of the waste water, it can achieve automatic operation, avoiding the problems of regular manual cleaning and waste water transfer of traditional devices, and improving the use efficiency.

[0017] Embodiment: When the liquid discharge tank moves to the leftmost side, at this time, the transmission sleeve also moves to the leftmost side until the transmission sleeve is sleeved with the transmission shaft. When the waste water enters the inside of the liquid discharge tank, it can drive the impeller to rotate. At this time, the power shaft rotates accordingly and drives the main shaft to rotate through the transmission shaft, and drives a plurality of flocculation rods to rotate. Cooperating with the flocculant inside the water storage tank, the capture of solids and suspended matters inside the water storage tank can be completed, and the automatic cleaning process can be completed.

[0018] The buoyancy of the wastewater is utilized to realize the automatic leftward shift of the drainage assembly, and the impact of the wastewater automatically drives the main shaft and the flocculation rod to rotate, thereby capturing floccules and solids. The entire capturing process can be completed inside the water storage tank, realizing the collection of wastewater and the capture of floccules at the same time, without the need for external power assistance, thereby completing the effective capture of floccules and improving the cleaning efficiency.

[0019] As a further technical solution of the present invention, the injection assembly includes a mounting frame, one end of the mounting frame is connected to a water storage tank, a flocculant tank is fixedly installed on the top of the mounting frame, the interior of the flocculant tank is filled with flocculant, and an injection pipe is fixedly connected to the right side of the mounting frame near the bottom end, and the bottom end of the injection pipe is connected to the top of the water storage tank.

[0020] As a further technical solution of the present invention, a touch switch is fixedly installed at the top position of the right side of the flocculant tank, and a solenoid valve is installed at the output end of the injection tube. When the movable frame is at the highest point, the extension rod contacts the touch switch and the valve of the solenoid valve is opened.

[0021] When the extension rod rises to the highest point, the extension rod can trigger the switch of the touch switch. At this time, the solenoid valve at the output end of the injection tube is opened, and the flocculant inside the flocculant tank is discharged through the injection tube and enters the water storage tank through the injection tube, completing the automatic delivery of the flocculant. When the water level drops, the float plate drops accordingly, the touch switch is no longer in contact with the extension rod, and the delivery of the flocculant stops accordingly.

[0022] By reusing the buoyancy of the wastewater, the rising water level of the wastewater is used as a trigger to automatically release the flocculant. The entire process can be completed automatically, and the release of the flocculant is automatically shut down when the water level drops. The entire process can be automatically controlled by the water level, with a high degree of automation, further improving the pollution cleaning efficiency.

At this time, the floating plate rises with it until the floating plate rises to the highest point; S2: At this time, the extension rod contacts the touch switch, the solenoid valve of the injection pipe is opened, and the flocculant inside the flocculant tank is injected into the water storage tank through the injection pipe. At the same time, the connecting rod deflects obliquely upward and exerts a pulling force on the drainage tank, driving the drainage tank to move to the left until the drainage tank moves to the far left. S3: At this time, the receiving pipe can correspond to the drainage pipe, and the sewage inside the water storage tank can enter the inside of the receiving pipe through the drainage pipe, and then pass through the discharge tank, the discharge pipe, and finally be discharged after being filtered by the filter linkage assembly, completing the sewage discharge process; S4: At the same time, the transmission sleeve and the transmission shaft are connected. When the sewage enters the drainage tank, it can drive the impeller to rotate. At this time, the power shaft and the transmission sleeve rotate accordingly, and drive the transmission shaft and the main shaft to rotate. At this time, the flocculation rod rotates accordingly, and cooperates with the injected flocculant to capture the flocculants inside the water storage tank to complete the cleaning.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the buoyancy provided by the wastewater that continuously rises inside the water storage tank, and utilizes the cooperation between the linkage component and the drainage component to convert the upward force into the left and right forces, automatically drives the displacement of the drainage component, and automatically completes the wastewater discharge process through the drainage component. The entire process can be completed automatically, and at the same time, relying on the buoyancy of the wastewater and the water level, it can complete automatic operation, avoiding the problem of regular manual cleaning and wastewater transportation required by traditional devices, thereby improving utilization efficiency.

[0025] (2) The present invention utilizes the buoyancy of wastewater to achieve automatic leftward movement of the drainage assembly, and automatically drives the main shaft and flocculation rod to rotate through the impact of wastewater, thereby achieving the capture of floccules and solids. The entire capture process can be completed inside the water storage tank, achieving the collection of wastewater and the capture of floccules at the same time, and no external power assistance is required, thereby completing the effective capture of floccules and improving the cleaning efficiency.

[0026] (3) The present invention reuses the buoyancy of wastewater so that the rising water level of wastewater is used as a trigger condition to automatically release the flocculant. The entire process can be completed automatically, and the release of the flocculant is automatically shut down when the water level drops. The entire process can be automatically controlled by the water level, with a high degree of automation, further improving the cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 8 shown, in the embodiment of the present invention, a self-operating sewage cleaning device for a laboratory wastewater collection pool includes a water storage tank 1. A medicine injection component 3 is fixedly installed at a position near the top on the left side of the water storage tank 1. A water inlet pipe 2 is fixedly connected to a position near the bottom on the left side of the water storage tank 1. The other end of the water inlet pipe 2 is connected to the drainage end of the wastewater collection pool. The water storage tank 1 is used to collect wastewater. An extension guide rail 7 is fixedly installed on the right side of the water storage tank 1. A liquid discharge component 8 is movably clamped at the bottom of the extension guide rail 7. A drain pipe 5 is fixedly connected to a position near the top on the right side of the water storage tank 1. A booster pump 6 is built into the drain pipe 5. A linkage component 9 is fixedly installed at a position near the top on the left side of the liquid discharge component 8. A through hole 4 is opened in the middle of the top of the water storage tank 1. The bottom end of the linkage component 9 passes through the through hole 4 and is located inside the water storage tank 1. A main shaft 10 is movably installed in the middle of the water storage tank 1. The right end of the main shaft 10 passes through the right end of the water storage tank 1 and is fixedly connected to a transmission shaft 11. When the liquid discharge component 8 is at the leftmost position, the left side of the liquid discharge component 8 is fixedly sleeved with the transmission shaft 11, and the front end of the liquid discharge component 8 is connected to the drain pipe 5. Flocculation rods 12 are fixedly installed at equal intervals on the outer side of the main shaft 10 and are located inside the water storage tank 1.

[0030] Before cleaning the waste water, the water inlet pipe 2 can be connected to the output end of the waste water collection tank. The waste water generated in the laboratory can enter the interior of the water storage tank 1 through the water inlet pipe 2. As the waste water enters, the liquid level of the waste water inside the water storage tank 1 rises accordingly.

[0031] As Figure 1 and Figure 3 and Figure 6 As shown in the figures, the linkage assembly 9 includes a movable frame 901. At the top of the movable frame 901, an extension rod 902 is fixedly installed directly below the medicine injection assembly 3. At the bottom of the movable frame 901, an extension column 903 is fixedly installed. The bottom end of the extension column 903 penetrates through the bottom end of the through hole 4 and is fixedly installed with a floating plate 904 inside the water storage tank 1. On the right side of the movable frame 901, a first fixed seat 905 is fixedly installed. One end of the first fixed seat 905 away from the movable frame 901 is movably connected to a connecting rod 907 through a rotating shaft. One end of the connecting rod 907 away from the first fixed seat 905 is movably connected to a second fixed seat 906 through a rotating shaft. The other end of the second fixed seat 906 is connected to the liquid discharge assembly 8.

[0032] As the liquid level of the waste water rises, the buoyancy received by the floating plate 904 inside the water storage tank 1 increases accordingly, driving the floating plate 904 to move upward. At this time, the extension column 903 moves upward accordingly until the movable frame 901 rises to the highest point. At this time, the extension rod 902 also rises to the highest point. When the movable frame 901 rises, it can drive the connecting rod 907 to deflect obliquely upward and apply a leftward pulling force to the liquid discharge tank 801.

[0033] As Figure 3 and Figure 5 and Figure 7 and Figure 8 As shown in the figures, at the top of the liquid discharge tank 801, a guide block 807 is fixedly installed. The liquid discharge tank 801 is movably clamped with the extension guide rail 7 through the guide block 807. The liquid discharge tank 801 moves left and right relative to the extension guide rail 7. The second fixed seat 906 is connected to the left side of the liquid discharge tank 801. At a position near the top of the front surface of the liquid discharge tank 801, a connecting pipe 802 is fixedly connected. On the front surface of the connecting pipe 802, a sealing plate 803 is fixedly installed. At a position near the bottom of the back surface of the liquid discharge tank 801, a discharge pipe 808 is fixedly connected. At the rear end of the discharge pipe 808, a filter screen linkage assembly 9 is fixedly installed. In the middle of the liquid discharge tank 801, a power shaft 804 is movably installed. On the outer side of the power shaft 804, an impeller 806 inside the liquid discharge tank 801 is fixedly sleeved. The left side of the power shaft 804 penetrates through the left side of the liquid discharge tank 801 and is fixedly connected to a transmission sleeve 805. When the liquid discharge tank 801 is at the leftmost position, the transmission sleeve 805 is movably sleeved with the transmission shaft 11, and the connecting pipe 802 and the drain pipe 5 correspond to each other and are connected to each other.

[0034] Embodiment: When the drain tank 801 is subjected to a pulling force toward the left, the drain tank 801 can be displaced toward the left under the guidance of the guide block 807 and the extended guide rail 7 until the drain tank 801 moves to the leftmost side. When the drain tank 801 has not moved to the leftmost side, the sealing plate 803 can block the output end of the drain pipe 5. When the drain tank 801 moves to the leftmost side, the drain pipe 5 can correspond to the receiving pipe 802. The waste water inside the water storage tank 1 can enter the interior of the receiving pipe 802 through the drain pipe 5, and after passing through the drain tank 801, it is discharged after being filtered by the discharge pipe 808 and the filter linkage assembly 9, thereby completing the automatic sewage cleaning process.

[0035] By utilizing the buoyancy provided by the wastewater that continuously rises inside the water storage tank 1, and utilizing the cooperation between the linkage component 9 and the drainage component 8 to convert the upward force into the left and right force, the displacement of the drainage component 8 is automatically driven, and the wastewater discharge process is automatically completed through the drainage component 8. The entire process can be completed automatically, and at the same time, relying on the buoyancy of the wastewater and the water level, automatic operation can be completed, avoiding the problem of regular manual cleaning and wastewater transportation required by traditional devices, thereby improving utilization efficiency.

[0036] Embodiment: When the drainage tank 801 moves to the leftmost side, the transmission sleeve 805 also moves to the leftmost side until the transmission sleeve 805 and the transmission shaft 11 are connected. When wastewater enters the drainage tank 801, the impeller 806 can be driven to rotate. At this time, the power shaft 804 rotates accordingly and drives the main shaft 10 to rotate through the transmission shaft 11, and drives multiple flocculation rods 12 to rotate. In conjunction with the flocculant inside the water storage tank 1, the solids and suspended matter inside the water storage tank 1 can be captured, completing the automatic cleaning process.

[0037] The buoyancy of the wastewater is utilized to realize the automatic leftward shift of the drainage assembly 8, and the impact of the wastewater automatically drives the main shaft 10 and the flocculation rod 12 to rotate, thereby capturing floccules and solids. The entire capturing process can be completed inside the water storage tank 1, thereby realizing the collection of wastewater and the capture of floccules at the same time, and no external power assistance is required, thereby completing the effective capture of floccules and improving the cleaning efficiency.

[0038] like Figure 1 and Figure 2 as well as Figure 3As shown in the figure, the medicine injection assembly 3 includes a mounting frame 301. One end of the mounting frame 301 is connected to the water storage tank 1. A flocculant tank 302 is fixedly installed at the top of the mounting frame 301. The flocculant tank 302 is filled with flocculant. A medicine injection pipe 303 is fixedly communicated at a position near the bottom on the right side of the mounting frame 301. The bottom end of the medicine injection pipe 303 is communicated with the top end of the water storage tank 1. A touch switch 304 is fixedly installed at the top right position of the flocculant tank 302. An electromagnetic valve is installed at the output end of the medicine injection pipe 303. When the movable frame 901 is at the highest point, the extension rod 902 contacts the touch switch 304, and the valve of the electromagnetic valve opens.

[0039] Moreover, when the extension rod 902 rises to the highest point, the extension rod 902 can trigger the switch of the touch switch 304. At this time, the electromagnetic valve at the output end of the medicine injection pipe 303 opens accordingly. The flocculant located inside the flocculant tank 302 is then exported through the medicine injection pipe 303 and enters the inside of the water storage tank 1 through the medicine injection pipe 303, completing the automatic feeding of the flocculant. When the water level drops, the floating plate 904 drops accordingly, the touch switch 304 no longer contacts the extension rod 902, and the feeding of the flocculant stops.

[0040] By reusing the buoyancy effect of the wastewater, the water level of the wastewater rises as a trigger condition to achieve the automatic feeding of the flocculant. The whole process can be completed automatically, and the feeding of the flocculant is automatically closed when the water level drops. The whole process can be automatically controlled by the water level height, with a high degree of automation, further improving the sewage cleaning efficiency.

[0041] A sewage cleaning method for a self-operating sewage cleaning device used in a laboratory wastewater collection tank includes the following steps: S1: Before sewage cleaning, the water inlet pipe 2 is communicated with the output end of the wastewater collection tank. The wastewater inside the wastewater collection tank can enter the inside of the water storage tank 1 through the water inlet pipe 2 and rise inside the water storage tank 1. At this time, the floating plate 904 rises accordingly until the floating plate 904 rises to the highest point position. S2: At this time, the extension rod 902 contacts the touch switch 304, the electromagnetic valve of the medicine injection pipe 303 is opened, the flocculant inside the flocculant tank 302 is put into the inside of the water storage tank 1 through the medicine injection pipe 303. At the same time, the connecting rod 907 deflects obliquely upward and applies a pulling force to the liquid discharge tank 801, driving the liquid discharge tank 801 to displace to the left until the liquid discharge tank 801 moves to the leftmost side. S3: At this time, the receiving pipe 802 can correspond to the drain pipe 5. The sewage inside the water storage tank 1 can enter the inside of the receiving pipe 802 through the drain pipe 5, and after passing through the liquid discharge tank 801, it passes through the discharge pipe 808 and is finally discharged after being filtered by the filter screen linkage assembly 9, completing the sewage discharge process. S4: Meanwhile, the socket connection between the transmission sleeve 805 and the transmission shaft 11 is completed. When sewage enters the inside of the liquid discharge tank 801, it can push the impeller 806 to rotate. At this time, the power shaft 804 and the transmission sleeve 805 rotate accordingly, and drive the transmission shaft 11 and the main shaft 10 to rotate. At this time, the flocculation rod 12 rotates accordingly, and cooperates with the injected flocculant to capture the flocs in the water storage tank 1, completing the cleaning of the sewage.
