Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a high-efficiency dissolved gas release device. Background Technology

[0002] The dissolved air release device is a key component in a pressure dissolved air flotation water purification system. Pressure dissolved air flotation is a novel water treatment technology that has been widely applied in my country and many other advanced industrialized countries. Only after the pressure dissolved air water passes through the release device to reduce pressure and dissipate energy can a large number of microbubbles be released. The performance of the release device affects the quantity of bubbles released, the fineness of the bubbles, and the distribution law of bubble size, directly influencing the water purification effect of the flotation method and the energy consumption.

[0003] Existing dissolved air release devices lack a filtration mechanism for the incoming water. As a result, particulate matter mixed in with wastewater can easily enter the dissolved air release device and accumulate inside, causing blockages. This necessitates stopping the device, disassembling it, and cleaning it, which reduces work efficiency. Therefore, we propose a high-efficiency dissolved air release device. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency dissolved gas release device to solve the problem mentioned in the background art that the existing dissolved gas release device does not have a filtration mechanism for the inlet water. As a result, particulate matter mixed in with sewage can easily enter the dissolved gas release device directly and accumulate inside, causing blockage. This requires stopping the machine to disassemble the dissolved gas release device for cleaning, which reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency dissolved gas release device, comprising a dissolved gas releaser body, an inlet pipe provided on the dissolved gas releaser body, an installation pipe provided at the top end of the inlet pipe, connecting rings fixedly installed on the outer surfaces of both the inlet pipe and the installation pipe, a plurality of connecting bolts threaded between the two connecting rings, a filter screen cylinder movably provided on the inner wall of the inlet pipe, an installation frame detachably installed on the inner wall of the filter screen cylinder, a motor fixedly installed on the upper surface of the installation frame, the output shaft of the motor extending to the lower part of the installation frame and fixedly installed on an installation plate, a cleaning brush detachably installed on the lower surface of the installation plate, the cleaning brush being attached to the lower surface of the inner wall of the filter screen cylinder.

[0006] The above solution involves setting up an inlet pipe and an installation pipe, with a filter screen between them. The filter screen filters the wastewater entering the dissolved gas release unit, effectively preventing particulate matter from entering and clogging the unit, thus extending its lifespan and improving efficiency. A mounting frame is used in conjunction with a cleaning brush; a motor on the frame drives the brush to rotate, cleaning and preventing clogging of the filter screen. This avoids water flow obstruction due to clogged mesh. The cleaning brush is also detachable for easy cleaning and replacement.

[0007] In the above scheme, it should be noted that the motor is electrically connected to an external power supply.

[0008] In a preferred embodiment, the two connecting rings are provided with sealing grooves on their opposite surfaces, and the two sealing grooves are arranged opposite each other and are fitted with the same sealing ring. The sealing ring is provided with a circular hole for the connecting bolt to pass through.

[0009] By adopting the above solution, the sealing ring can ensure good sealing performance between the two connecting rings, thereby ensuring that there will be no water leakage between the inlet pipe and the installation pipe.

[0010] In a preferred embodiment, a plurality of limiting strips are fixedly installed on the outer surface of the filter screen cylinder, and a plurality of limiting slots are opened on the inner wall of the inlet pipe, with the limiting strips inserted into the inner wall of the limiting slots.

[0011] By using the above solution, the limiting insert can be inserted into the limiting slot to achieve the limiting support effect on the filter cylinder and prevent the filter cylinder from tilting or moving.

[0012] In a preferred embodiment, a plurality of fixing blocks are fixedly installed on the inner wall of the filter cylinder, fixing screws are fixedly installed on the upper surface of the fixing blocks, the mounting bracket is fitted and arranged on the upper surface of the fixing blocks, the mounting bracket has through holes, the fixing screws pass through the through holes and are threaded with fixing nuts, and the fixing nuts are fitted and arranged on the upper surface of the mounting bracket.

[0013] By using the above solution, and employing fixing screws in conjunction with fixing nuts, the mounting bracket can be easily installed. The installation structure is simple and the operation is convenient.

[0014] In a preferred embodiment, a trapezoidal slot is provided on the lower surface of the mounting plate, and a trapezoidal insert is fixedly installed on the upper surface of the cleaning brush. The trapezoidal insert is inserted into the inner wall of the trapezoidal slot, and a baffle is fixedly installed at one end of the trapezoidal insert.

[0015] Using the above solution, a trapezoidal insert is inserted into a trapezoidal slot to perform the insertion of the mounting plate and cleaning brush. By setting a baffle, when the trapezoidal insert is inserted into the trapezoidal slot until the baffle touches the mounting plate, it indicates that the installation position has been reached, thus improving the convenience of the insertion operation.

[0016] In a preferred embodiment, the trapezoidal insert has a groove on its side, and a spring and a telescopic rod are fixedly installed on the inner wall of the groove. A locking plate is fixedly installed at the end of the spring and the telescopic rod. A locking hole for inserting the locking plate is opened on the side of the mounting plate, and the locking plate has an inclined surface at one corner.

[0017] The above solution utilizes the elasticity of the spring in conjunction with the locking plate. When the trapezoidal insert is inserted into the trapezoidal slot, the locking plate, having an inclined surface, will enter the groove after touching the mounting plate. At this point, the spring deforms, and after the trapezoidal insert is fully inserted, the spring force drives the locking plate to reset and insert into the lock hole, achieving insertion locking. The telescopic rod provides support, preventing the locking plate from shaking and improving the stability of the locking effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This high-efficiency dissolved gas release device is equipped with an inlet pipe and an installation pipe. A filter screen is installed between the inlet pipe and the installation pipe. The filter screen is used to filter the sewage entering the main body of the dissolved gas release device, effectively preventing particulate matter mixed in the sewage from entering the main body of the dissolved gas release device and causing accumulation and blockage. This effectively extends the service life of the main body of the dissolved gas release device and improves working efficiency.

[0020] This high-efficiency dissolved gas release device is used in conjunction with a cleaning brush by setting up a mounting frame. The motor on the mounting frame drives the cleaning brush to rotate, thereby cleaning and preventing clogging of the filter screen. This avoids the mesh from being blocked and affecting the smooth flow of water. In addition, the cleaning brush is designed to be detachable, making it easy to clean and replace.

[0027] Please see Figure 1-5 This utility model provides a high-efficiency dissolved gas release device, including a dissolved gas releaser body 1. An inlet pipe 2 is provided on the dissolved gas releaser body 1, and an installation pipe 3 is provided at the top end of the inlet pipe 2. Connecting rings 4 are fixedly installed on the outer surfaces of both the inlet pipe 2 and the installation pipe 3. Several connecting bolts 5 are threaded between the two connecting rings 4. A filter screen cylinder 6 is movably provided on the inner wall of the inlet pipe 2. An installation frame 7 is detachably installed on the inner wall of the filter screen cylinder 6. A motor 8 is fixedly installed on the upper surface of the installation frame 7. The output shaft of the motor 8 extends to the lower part of the installation frame 7 and is fixedly installed on an installation plate 9. A cleaning brush 10 is detachably installed on the lower surface of the inner wall of the installation plate 9. The cleaning brush 10 is attached to the lower surface of the inner wall of the filter screen cylinder 6.

[0028] By setting up an inlet pipe 2 and an installation pipe 3, and installing a filter screen 6 between the inlet pipe 2 and the installation pipe 3, the wastewater input into the dissolved gas release device body 1 is filtered by the filter screen 6, which effectively prevents particulate matter mixed in the wastewater from entering the interior of the dissolved gas release device body 1 and causing accumulation and blockage, effectively extending the service life of the dissolved gas release device body 1 and improving working efficiency. By setting up an installation frame 7 to work with the cleaning brush 10, the motor 8 on the installation frame 7 drives the cleaning brush 10 to rotate, realizing the cleaning and anti-clogging of the filter screen 6, avoiding the mesh blockage affecting the smooth flow of water, and the cleaning brush 10 is detachable for easy cleaning and replacement.

[0029] Both of the two connecting rings 4 have sealing grooves on their opposite surfaces, and the two sealing grooves are arranged opposite each other and are fitted with the same sealing ring 11. The sealing ring 11 has a circular hole for the connecting bolt 5 to pass through. The sealing ring 11 can ensure good sealing characteristics between the two connecting rings 4, thereby ensuring that there will be no water leakage between the inlet pipe 2 and the installation pipe 3.

[0030] A number of limiting inserts 12 are fixedly installed on the outer surface of the filter cylinder 6, and a number of limiting slots are opened on the inner wall of the inlet pipe 2. The limiting inserts 12 are inserted into the inner wall of the limiting slots. By inserting the limiting inserts 12 into the limiting slots, the limiting support effect of the filter cylinder 6 can be achieved, and the phenomenon of the filter cylinder 6 tilting or moving can be avoided.

[0031] The inner wall of the filter cylinder 6 is fixedly equipped with several fixing blocks 13. Fixing screws 14 are fixedly installed on the upper surface of the fixing blocks 13. The mounting frame 7 is fitted and arranged on the upper surface of the fixing blocks 13. The mounting frame 7 has through holes. The fixing screws 14 pass through the through holes and are threaded with fixing nuts 15. The fixing nuts 15 are fitted and arranged on the upper surface of the mounting frame 7. By using the fixing screws 14 and fixing nuts 15, the mounting frame 7 can be conveniently installed. The installation structure is simple and the operation is convenient.

[0032] The lower surface of the mounting plate 9 is provided with a trapezoidal slot, and the upper surface of the cleaning brush 10 is fixedly installed with a trapezoidal insert 20. The trapezoidal insert 20 is inserted into the inner wall of the trapezoidal slot, and a baffle 16 is fixedly installed at one end of the trapezoidal insert 20. The mounting plate 9 and the cleaning brush 10 are inserted into the trapezoidal slot by using the trapezoidal insert 20. By setting the baffle 16, when the trapezoidal insert 20 is inserted into the trapezoidal slot until the baffle 16 touches the mounting plate 9, it indicates that the installation position has been reached, which improves the convenience of the insertion operation.

[0033] The trapezoidal insert 20 has a groove on its side, and a spring 18 and a telescopic rod 17 are fixedly installed on the inner wall of the groove. A locking plate 19 is fixedly installed at the end of the spring 18 and the telescopic rod 17. The mounting plate 9 has a locking hole on its side for the locking plate 19 to be inserted. The locking plate 19 has an inclined surface at one corner. The spring 18 is used to cooperate with the locking plate 19. When the trapezoidal insert 20 is inserted into the trapezoidal slot, the locking plate 19 will enter the groove after touching the mounting plate 9 because of the inclined surface on the locking plate 19. At this time, the spring 18 deforms, and after the trapezoidal insert 20 is fully inserted, the elastic force of the spring 18 drives the locking plate 19 to return to the locking hole and achieve insertion locking. The telescopic rod 17 provides a supporting effect to prevent the locking plate 19 from shaking and improve the stability of the locking effect.

[0034] During use, wastewater enters the inlet pipe 2 through the installation pipe 3 and then flows through the filter cylinder 6. The filter cylinder 6 filters particulate matter in the wastewater. The filtered wastewater enters the dissolved gas release unit 1. At the same time, the motor 8 drives the mounting plate 9 to rotate the cleaning brush 10, thereby cleaning the filter cylinder 6 and preventing the mesh from clogging. After the operation is completed, unscrew the connecting bolt 5 to release the lock between the inlet pipe 2 and the installation pipe 3. Then, disassemble the installation pipe 3 and the inlet pipe 2, and then take out the filter cylinder 6 upwards. Then, unscrew the fixing nut 15 and take out the mounting bracket 7 upwards. Press the locking plate 19 to disengage the locking plate 19 from the locking hole. At this time, slide the cleaning brush 10 to disengage the trapezoidal insert 20 from the mounting plate 9, completing the disassembly of the cleaning brush 10.
