Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a disinfection device for sewage treatment. Background Art

[0002] In modern production industry and production life, with the increasing demand for water in people's lives and industrial production, there is an increasing need to effectively and quickly treat sewage so that sewage can be quickly treated into living or industrial water that meets the standards. By treating sewage, environmental pollution and water shortage problems can be effectively improved. By reusing water resources, water costs can be effectively reduced and waste of water resources can be avoided. Sewage is rich in various bacteria, viruses and other microorganisms, which need to be effectively sterilized before the next sewage treatment operation. Currently, modular ultraviolet lamp groups are placed in water tanks to irradiate and sterilize flowing water. The sterilization effect of ultraviolet light kills bacteria and other microorganisms in the water. However, the ultraviolet lamp group is prone to attaching a layer of pollutants on the surface of the quartz tube during long-term work, and even hangs on flocs in the sewage, which greatly reduces the ultraviolet light sterilization effect. It is necessary for personnel to take out the ultraviolet lamp group for cleaning regularly. The inability to clean it frequently also greatly increases the labor intensity of the operators. At the same time, due to the uncertain water level in the water tank, sometimes most of the ultraviolet lamp group is exposed to the water surface, which reduces the disinfection effect and wastes the energy to maintain its operation.

[0003] For example, an ultraviolet disinfection device with a publication number of CN104671331B includes a lamp holder, a water outlet weir gate, a multi-layer disinfection ultraviolet lamp, a main control machine and a liquid level sensor. The lamp holder and the water outlet weir gate are arranged in the disinfection channel, and the lamp holder is located on the water storage side of the water outlet weir gate. The water outlet weir gate is provided with a plurality of water outlet slots of different heights. The multi-layer disinfection ultraviolet lamps are arranged on the lamp holder from top to bottom in sequence. Each layer of disinfection ultraviolet lamps is connected to the main control machine. The liquid level sensor is arranged above the liquid level in the disinfection channel to detect the height of the liquid level. The liquid level sensor is connected to the main control machine. The above-mentioned disinfection device only turns on the lamp tubes below the liquid level through the setting of the liquid level sensor, thereby reducing energy waste, but cannot concentrate the lamp tubes below the water level to improve the disinfection efficiency, and cannot achieve the effect of automatically cleaning the lamp tubes. Therefore, the present application designs a sewage treatment disinfection device that can automatically clean the ultraviolet lamp tubes by rotating them during reciprocating movement, and change the position and spacing of the lamp tubes. Summary of the invention

[0006] By rotating and displacing the gears in the rack track formed by the fixed track and the modular track, the cleaning mechanism is driven to rotate along the track to clean all the ultraviolet lamps, and the stains and flocs on the ultraviolet lamps are cleaned off. This can effectively improve the disinfection efficiency of the ultraviolet lamps working for a long time, ensure the disinfection effect of the device, reduce the number and frequency of manual cleaning, and reduce the labor intensity of operators.

[0007] Furthermore, the top plate and the modular track are arranged in an array, and the top plates are connected by sliding buckles. The top plate is placed on a reserved bracket on the upper part of the sink, and the number of the top plate and the modular track is adjusted according to the width of the sink, and a handle is arranged on the upper end of the top plate.

[0008] Furthermore, an arc-shaped support plate is provided at the lower end of the fixed track and the modular track, and the other end of the arc-shaped support plate is plugged into the lower part of the vertical plate, and round nails are arranged evenly on the surface of the arc-shaped support plate. While the fixed track and the modular track are supported by the arc-shaped support plate, the fixed track and the modular track are internally connected after the top plate is slid and engaged, and the modular tracks are internally connected after the top plate is slid and engaged. The round nails are provided to scrape off the floccules and other debris cleaned by the cleaning mechanism when the cleaning mechanism moves to the bottom, thereby cleaning the cleaning mechanism, preventing the accumulation of floccules on the surface of the cleaning mechanism from reducing the cleaning efficiency, allowing the cleaning mechanism to be used for a longer time, and reducing the frequency of manual cleaning and maintenance by operators.

[0009] Furthermore, the cleaning mechanism includes a waterproof shell, a motor, a screw, a threaded sleeve, a sliding rod, a first slider and a brush roller; the upper end of the waterproof shell is connected to the top plate bolt, the motor is arranged at the upper end of the waterproof shell, the output end of the motor is plugged into the screw, the threaded sleeve is placed on the screw, the screw and the inner wall of the waterproof shell have a limited sliding connection to prevent the threaded sleeve from rotating, the side of the threaded sleeve is plugged into the sliding rod, the sliding rod extends out of the waterproof shell, the first slider slides in the sliding rod, the first slider extends out of the sliding rod and is fixedly plugged into the gear, and one end of the brush roller is fixedly plugged into the end of the gear away from the first slider.

[0010] Furthermore, a limiter is arranged inside the slide bar so that the first slide bar can be displaced horizontally in one direction. An electromagnetic block is arranged at the lower end of the limiter. The electromagnetic block changes the limiting direction of the limiter by changing the magnetic pole. Switch buttons are arranged at both ends of the slide bar. When the first slide bar touches the switch button, the magnetic pole of the electromagnetic block is reversed. The slide bar is composed of an array of short rods spliced ​​together.

[0011] Furthermore, the displacement mechanism includes an electric push rod, a connecting rod, a second slider and a pulling rod. The electric push rod is arranged at the upper end of the vertical plate. The array of connecting rods are rotatably connected to each other to form a diamond-shaped telescopic structure. One end of the pulling rod is plugged into the lower end of the electric push rod, and the other end of the pulling rod is connected to the node at the upper end formed between the connecting rods.

The second slider extends out of the vertical plate, and the second slider is slidably connected to the vertical plate with a waterproof seal; the end of the second slider away from the vertical plate is plugged into the ultraviolet lamp tube, wherein the electric push rod is connected to the motor electrical signal.

[0012] By setting up the displacement mechanism, when the water level drops, the electric push rod drives the connecting rod to rotate and displace, so that the spacing between the ultraviolet lamp tubes changes, and the ultraviolet lamp tubes are displaced downward as a whole, so that the ultraviolet lamp tubes can be completely immersed in water, thereby enhancing the sewage disinfection efficiency of the device and reducing energy waste. At the same time, the electric push rod is connected to the electrical signal of the motor, so that the cleaning mechanism and the displacement mechanism can be started synchronously. When the cleaning mechanism is working, the displacement mechanism drives the ultraviolet lamp tube to reciprocate, so that the brush roller and the ultraviolet lamp tube move relative to each other, and the brush roller has a better cleaning effect on the lamp tube, reducing cleaning dead corners.

[0014] By rotating and displacing the gears in the rack track formed by the fixed track and the modular track, the cleaning mechanism is driven to rotate along the track to clean all the ultraviolet lamps, and the stains and flocs on the ultraviolet lamps are cleaned off. This can effectively improve the disinfection efficiency of the ultraviolet lamps working for a long time, ensure the disinfection effect of the device, reduce the number and frequency of manual cleaning, and reduce the labor intensity of operators.

[0015] The round nails provided can scrape off the flocs and other debris cleaned by the cleaning mechanism when the cleaning mechanism moves downward, thereby cleaning the cleaning mechanism and preventing the flocs from accumulating on the surface of the cleaning mechanism, which leads to a decrease in cleaning efficiency. This allows the cleaning mechanism to be used for a longer time and reduces the frequency of manual cleaning and maintenance by operators.

[0016] By setting up the displacement mechanism, when the water level drops, the electric push rod drives the connecting rod to rotate and displace, so that the spacing between the ultraviolet lamp tubes changes, and the ultraviolet lamp tubes are displaced downward as a whole, so that the ultraviolet lamp tubes can be completely immersed in water, thereby enhancing the sewage disinfection efficiency of the device and reducing energy waste. At the same time, the electric push rod is connected to the electrical signal of the motor, so that the cleaning mechanism and the displacement mechanism can be started synchronously. When the cleaning mechanism is working, the displacement mechanism drives the ultraviolet lamp tube to reciprocate, so that the brush roller and the ultraviolet lamp tube move relative to each other, and the brush roller has a better cleaning effect on the lamp tube, reducing cleaning dead corners.

DETAILED DESCRIPTION

[0029] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0030] like Figures 1 to 10 As shown, the present application proposes a disinfection device for sewage treatment, comprising a top plate 1, a vertical plate 2, an ultraviolet lamp tube 3, a displacement mechanism 4 and a cleaning mechanism 5 for reciprocatingly cleaning the ultraviolet lamp tube 3; the vertical plate 2 extends downward through the top plate 1, the displacement mechanism 4 is arranged inside the vertical plate 2, the rear ends of the ultraviolet lamp tubes 3 evenly arranged in an array are plugged into the displacement mechanism 4, and the cleaning mechanism 5 is detachably connected to the lower end of the top plate 1; a fixed track 6, a modular track 7 and a gear 8 are arranged inside the cleaning mechanism 5, and the upper end of the fixed track 6 is connected to the lower end of the top plate 1 away from the vertical plate 2. The upper end of the modular track 7 is plugged into the lower end of the top plate 1 away from the vertical plate 2. Racks 9 are provided in the fixed track 6 and the modular track 7. The gear 8 is engaged with the rack 9. The end of the rack 9 close to the vertical plate 2 is plugged into the cleaning mechanism 5; the displacement mechanism 4 slides inside the vertical plate 2, thereby driving the ultraviolet lamp 3 to move in the vertical direction to adapt to water bodies of different depths. The gear 8 moves back and forth and rotates through engagement with the rack 9 and moves along the track, thereby driving the cleaning mechanism 5 to rotate and clean the ultraviolet lamp 3.

[0031] See also Figure 1 , the top plate 1 and the modular rails 7 are arranged in an array, and the top plates 1 are connected by sliding buckles. When the device is installed, the fixed rails 6 are plugged into the lower end of the top plate 1, and then the appropriate number of modular rails 7 are plugged into the top plate 1 according to the actual width of the on-site sink.

[0032] See also Figure 1, the top plate 1 is placed on the reserved bracket on the top of the sink, the number of top plates 1 and modular rails 7 is adjusted according to the width of the sink, and a handle 11 is provided on the top of the top plate 1. Hold the handle 11 to place the top plate 1 with the fixed rail 6 on the bracket, and then slide the top plate 1 plugged with the modular rail 7 into the side of the placed top plate 1, so that the top plates 1 are slidably plugged in, and finally place the top plate 1 with the fixed rail 6 on the other side to complete the installation of the device.

[0033] As another example, Figures 1 to 4 As shown, an arc-shaped support plate 61 is provided at the lower end of the fixed track 6 and the modular track 7, and the other end of the arc-shaped support plate 61 is plugged into the lower part of the vertical plate 2, and the surface of the arc-shaped support plate 61 is provided with evenly arranged round nails 611.

[0034] See also Figure 1 The fixed track 6 and the modular track 7 are internally connected after the top plate 1 is slidably engaged, and the modular tracks 7 are internally connected after the top plate 1 is slidably engaged. Thus, the device forms a complete rack 9 track.

[0035] As another example, Figure 2 , Figure 5 as well as Figures 7 to 9 As shown, the cleaning mechanism 5 includes a waterproof shell 51, a motor 52, a screw 53, a threaded sleeve 54, a slide bar 55, a first slider 56 and a brush roller 57; the upper end of the waterproof shell 51 is bolted to the top plate 1, the motor 52 is arranged at the upper end of the waterproof shell 51, the output end of the motor 52 is plugged into the screw 53, the threaded sleeve 54 is sleeved on the screw 53, the screw 53 and the inner wall of the waterproof shell 51 are slidingly connected with a limited position to prevent the threaded sleeve 54 from rotating, the side of the threaded sleeve 54 is plugged into the slide bar 55, the slide bar 55 extends out of the waterproof shell 51, the first slider 56 slides in the slide bar 55, the first slider 56 extends out of the slide bar 55 and is fixedly plugged into the gear 8, and one end of the brush roller 57 is fixedly plugged into the end of the gear 8 away from the first slide bar 56.

[0036] When the ultraviolet lamp 3 needs to be cleaned, the motor 52 is started, so that the motor 52 drives the screw 53 to rotate, and the rotation of the screw 53 causes the threaded sleeve 54 to move vertically along the inside of the waterproof shell 51, driving the sliding rod 55 to move synchronously, so that the sliding rod 55 drives the first slider 56 to move vertically, so that the gear 8 moves along the track formed by the rack 9, and the gear 8 rotates, thereby driving the brush roller 57 to rotate, and the brush roller 57 is able to rotate again to clean the ultraviolet lamp 3 with the bristles, and the stains and flocs attached to the ultraviolet lamp 3 are cleaned onto the bristles. When the brush roller 57 moves to the lower end of the track, its bristles contact the round nails 611, and during the rotation of the brush roller 57, the round nails 611 scrape the flocs on the surface of the bristles and collect them in the arc-shaped support plate 61. The motor 52 continuously rotates back and forth, driving the threaded sleeve 54 to perform reciprocating motion in the vertical direction. It should be noted that the screw 53, the motor 52 and the threaded sleeve 54 can be symmetrically arranged on the sides of the fixed track 6 to enhance the stability of the device. The threads of the symmetrically arranged screw 53 are reversely arranged.

[0037] See also Fig. 9 , a limiter 551 is arranged in the slide bar 55 to make the first slide bar 56 move horizontally in one direction, an electromagnetic block 552 is arranged at the lower end of the limiter 551, and the electromagnetic block 552 changes the limiting direction of the limiter 551 by changing the magnetic pole, and a switching button 553 is arranged at both ends of the slide bar 55, and the first slide bar 56 touches the switching button 553 to reverse the magnetic pole of the electromagnetic block 552. The horizontal position of the limiter 551 is the same as the horizontal position of the track bending. When the slider moves to the upper or lower end of the track, the slider is driven to move horizontally on the slide bar 55 due to the bending of the track. The limiter 551 is set so that the slider can only move horizontally in one direction to prevent the gear 8 from passing through the turning part of the track. When the slider moves to the rightmost end and contacts the switching button 553, the magnetic pole of the electromagnetic block 552 is reversed, and then the limiter 551 is started to reverse, so that the direction of limiting the horizontal displacement of the slider is opposite, and then the gear 8 can drive the brush roller 57 to return to the initial position. It should be noted that the slide bar 55 is formed by connecting a plurality of short bars to each other, so as to be suitable for the modular design of the device.

[0038] As another example, Figure 2 , Figure 6 as well as Fig.10As shown, the displacement mechanism 4 includes an electric push rod 41, a connecting rod 42, a second slider 43 and a pulling rod 44. The electric push rod 41 is arranged at the upper end of the vertical plate 2. The array connecting rods 42 are rotatably connected to each other to form a diamond-shaped telescopic structure. One end of the pulling rod 44 is plugged into the lower end of the electric push rod 41, and the other end of the pulling rod 44 is connected to the node at the upper end formed between the connecting rods 42. The second slider 43 is connected to the connecting rod 42 at each node between the connecting rods 42. The lowermost node of the connecting rod 42 is rotatably connected to the inner wall of the vertical plate 2. The second slider 43 extends out of the vertical plate 2, and the second slider 43 is slidably connected to the vertical plate 2 with a waterproof seal. When the water level in the sink changes, the electric push rod 41 starts to cause the pulling rod 44 to move in the vertical direction, driving the connecting rod 42 to rotate, so that the diamond structure formed between the connecting rods 42 is expanded or pulled up, so that the second slider 43 slides on the vertical plate 2, changing the spacing and vertical position of the ultraviolet lamps 3, making it suitable for different water levels and ensuring that all the ultraviolet lamps 3 are submerged in water.

[0039] See also Figure 6 The end of the second slider 43 away from the vertical plate 2 is plugged into the ultraviolet lamp 3. Furthermore, the electric push rod 41 is connected with the motor 52 by electrical signals. When the motor 52 is started, the electric push rod 41 reciprocates, so that the ultraviolet lamp 3 and the brush roller 57 move relative to each other when the brush roller 57 rotates to clean the ultraviolet lamp 3, so that the cleaning effect of the cleaning mechanism 5 is better, and the cleaning dead angle is reduced.

[0040] Working principle: When in use, the fixed track 6 is plugged into the lower end of the top plate 1, and then the appropriate number of modular tracks 7 are plugged into the top plate 1 according to the actual width of the water tank on site. The top plate 1 with the fixed track 6 is placed on the bracket by holding the handle 11, and then the top plate 1 plugged into the modular track 7 is slid and inserted into the side of the placed top plate 1 in this way, so that the top plates 1 are slidably plugged in, and finally the top plate 1 with the fixed track 6 on the other side is placed to complete the installation of the device. When cleaning is required, the motor 52 is started, so that the motor 52 reciprocates forward and reverse, thereby driving the screw 53 to rotate, so that the threaded sleeve 54 reciprocates in the vertical direction, driving the gear 8 to move on the rack 9 track and causing the gear 8 to rotate, driving the brush roller 57 to rotate along the track to clean the ultraviolet lamp 3. When the water level changes, the electric push rod 41 is started, and the pull rod 44 is driven to move in the vertical direction according to the actual water level on site, thereby causing the diamond structure formed between the connecting rods 42 to stretch or compress, thereby changing the distance between the ultraviolet lamps 3 and the overall height.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
