Description

Technical field:

[0002] The invention relates to a centrifugal rotating nozzle for pipeline disinfection and a working method. Background technology:

[0004] The nozzle is a key component in many spraying, atomizing, oil spraying, spraying and other equipment, and plays an important role. The nozzle is widely used in various equipment, such as automobiles, high-pressure cleaning, dust removal, cooling, gardening and other different fields. Due to different uses, the materials are also different, such as stainless steel, plastic silicon carbide and other materials; currently common atomizing nozzles include pressure atomizing, centrifugal, medium atomizing, impact and so on.

[0005] The centrifugal atomizing nozzle has a swirl chamber structure inside. The fluid forms a thin liquid film inside the nozzle. After being sprayed out of the nozzle, the liquid surface tension overcomes the inertial force and breaks into droplets under the action of aerodynamic force. As the pressure increases, the injection speed increases, the liquid film breaks into filaments or ribbons, and the relative movement with the air intensifies. The liquid film can even be atomized as it leaves the nozzle. This type of nozzle has the advantage of sufficient atomization.

[0006] An analysis of existing patents and products found that in order to drive the turbine to rotate with high-speed water flow, the water flow needs to pass through a long pressurized pipe, which increases the volume of the nozzle. The water flow will also damage the turbine during the impact of the turbine, reducing the service life and life of the nozzle; one end of the boost pipe is connected to the turbine body and the other end is connected to the water inlet. The turbine is connected to the turbine seat, which limits the direction of the nozzle outlet. The spraying direction cannot be changed when the inside of the pipe is disinfected, and the spraying range is relatively small; in addition, traditional nozzles lack corresponding protection measures. After use, they are exposed to the air, and dust and bacteria are easy to enter. The nozzle holes are small and difficult to clean, which can easily breed bacteria and viruses, posing potential health and safety hazards; existing nozzles are mostly made of stainless steel, but stainless steel has poor wear resistance. During the use of the nozzle, the water flow will cause cavitation and damage the nozzle. Summary of the invention:

[0008] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a centrifugal rotating nozzle and a working method for pipeline disinfection. The centrifugal rotating nozzle for pipeline disinfection has a reasonable structural design, does not require components such as a booster pipe, and improves the spraying effect.

[0009] The present invention is a centrifugal rotating nozzle for pipeline disinfection, which is characterized by comprising a horizontally arranged water inlet pipeline and a plurality of fixed jackets arranged at intervals in the length direction of the water inlet pipeline, a motor and a rotating shaft arranged on the output end of the motor and passing through the water inlet pipeline from top to bottom are arranged above the fixed jacket, a wear-resistant pipe sleeve connected to the lower opening of the water inlet pipeline is connected below the water inlet pipeline, the lower outer peripheral sleeve of the wear-resistant pipe sleeve is provided with a conical shell sleeve that rotates with the rotating shaft, the lower end of the rotating shaft is fixedly connected with a rotating blade, and circular small holes for spraying water are arranged on the conical shell sleeve.

[0010] Furthermore, the above-mentioned fixed jacket is a rectangular shell, and its two sides are locked and fixed to the water inlet pipe by bolts that penetrate into the shell from the outside to the inside. The wear-resistant pipe sleeve is fixed on the opening at the bottom of the fixed jacket, and the upper edge of the wear-resistant pipe sleeve is sealed and connected to the periphery of the lower opening of the water inlet pipe.

[0011] Furthermore, the above-mentioned conical shell sleeve includes a forward conical shell sleeve and an inverted conical shell sleeve which are fixedly connected, and a curved spherical shell which is relatively fixed to the wear-resistant tube sleeve is sleeved between the conical shell sleeve and the wear-resistant tube sleeve.

[0012] Furthermore, the rotating shaft is connected to the conical shell through a connecting rod to realize the rotation of the conical shell.

[0013] Furthermore, a silicone protective sleeve is provided on the lower part of the conical shell.

[0014] Furthermore, the wear-resistant pipe sleeve is formed by bamboo plywood covering a stainless steel outer shell.

[0015] Furthermore, a cover shell for covering the motor is provided above the fixing jacket, and the cover shell is connected and fixed to the fixing jacket by connecting screws.

[0016] Furthermore, the rotating shaft extending into the water inlet pipe is in water-tight sleeve connection with the water inlet pipe.

[0017] The working method of the centrifugal rotating nozzle for pipeline disinfection of the present invention is characterized in that: the centrifugal rotating nozzle for pipeline disinfection comprises a horizontally arranged water inlet pipeline and a plurality of fixed jackets arranged at intervals in the length direction of the water inlet pipeline, a motor and a rotating shaft arranged on the output end of the motor and passing through the water inlet pipeline from top to bottom are arranged above the fixed jacket, a wear-resistant pipe sleeve connected to the lower opening of the water inlet pipeline is connected below the water inlet pipeline, the lower outer peripheral sleeve of the wear-resistant pipe sleeve is provided with a conical shell sleeve rotating with the rotating shaft, the lower end of the rotating shaft is fixedly connected with rotating blades, and circular small holes for spraying water are arranged on the conical shell sleeve; when working, water flows in the water inlet pipeline and enters the conical shell sleeve after passing through the wear-resistant pipe sleeve from the water inlet pipeline, and the water in the conical shell sleeve is thrown out from the circular small holes of the conical shell sleeve under the action of the rotation of the rotating blades, so that water is sprayed out to form droplets with smaller diameters.

[0018] Furthermore, a silicone protective cover is provided on the lower part of the conical shell. The silicone protective cover is removed when the conical shell is spraying water, and is put on when the conical shell is not in use.

[0019] The centrifugal rotating nozzle for pipeline disinfection of the present invention drives the liquid in the cavity to rotate with the rotating blades made of wear-resistant material, and after a certain centrifugal force is generated, the liquid is sprayed out from the outlet, thereby eliminating the step of the fluid passing through the booster pipe and reducing the size of the nozzle. After the booster pipe is removed, the conical shell (nozzle) is no longer restricted by direction, and the conical shell nozzle end and the water inlet of the wear-resistant pipe sleeve are connected by an arc spherical shell, so that the conical shell spray can be rotated 360 degrees in all directions without dead angles. During the use of the conical shell nozzle, the spraying direction can be switched at any time, so that the internal use area can be completely cleaned and disinfected.

[0026] In order to make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description.

[0027] The centrifugal rotating nozzle for pipeline disinfection of the present invention comprises a horizontally arranged water inlet pipeline 3 and a plurality of fixed jackets 5 arranged at intervals in the length direction of the water inlet pipeline 3. The number of the fixed jackets 5 can be determined according to actual needs. After determining the installation position, a through opening 15 for connecting with the wear-resistant pipe sleeve 6 and a through hole for inserting the rotating shaft 11 (and the water sealing sleeve) need to be opened on the water inlet pipeline 3.

[0028] A motor 1 and a rotating shaft 11 arranged on the output end of the motor 1 and passing through the water inlet pipe 3 from top to bottom are arranged above the fixed jacket 5. A wear-resistant pipe sleeve 6 connected to its lower opening 15 is connected below the water inlet pipe 3. The lower outer periphery of the wear-resistant pipe sleeve 6 is provided with a conical shell sleeve 8 that rotates with the rotating shaft 11. A rotating blade 10 is fixedly connected to the lower end of the rotating shaft 11, and circular small holes 14 for spraying water are arranged on the conical shell sleeve 8.

[0029] In order to realize the rotation of the conical shell 8, the above-mentioned rotating shaft 11 is connected with the conical shell 8 through the connecting rod 2 to realize the rotation of the conical shell. The rotating shaft 11, the connecting rod 2 and the conical shell 8 can be detachably connected.

[0030] Furthermore, in order to achieve wear resistance and installation, the wear-resistant pipe sleeve 6 is formed by covering the outer periphery of the stainless steel shell with bamboo plywood, and the bamboo plywood can be bonded to the outer periphery of the stainless steel shell by glue.

[0031] Furthermore, the above-mentioned fixed jacket 5 is a rectangular shell, and its two sides are locked and fixed to the water inlet pipe 3 by bolts 4 that penetrate into the shell from the outside to the inside. The wear-resistant pipe sleeve 6 is fixed on the opening 17 at the bottom of the fixed jacket 5, and the upper edge of the wear-resistant pipe sleeve 6 is sealed with the edge of the lower opening 15 of the water inlet pipe. The sealed connection can be achieved by a waterproof sealing ring to prevent water in the water inlet pipe 3 from flowing into the fixed jacket 5.

[0032] The rotating blades 10 move at high speed under the action of the motor 1, and the droplets formed are highly atomized, and can be sprayed at all directions in the pipeline, with a wide spraying range and high efficiency.

[0033] Furthermore, the above-mentioned conical shell sleeve 8 includes a fixedly connected positive conical shell sleeve 801 and an inverted conical shell sleeve 802, the positive conical shell sleeve 801 is a positive truncated cone shell, and the inverted conical shell sleeve 802 is an inverted truncated cone shell. The lower part of the positive conical shell sleeve 801 is fixedly connected to the upper part of the inverted conical shell sleeve 802 to form a whole, which can be made by integral stamping. An arc spherical shell 7 relatively fixed to the wear-resistant tube sleeve is sleeved between the conical shell sleeve and the wear-resistant tube sleeve, and the inner periphery of the arc spherical shell 7 is fixed to the outer periphery of the wear-resistant tube sleeve 6. The conical shell sleeve 8 is connected to the outer surface of the arc spherical shell 7 in a slidable or relatively rotatable manner. The conical shell sleeve 8 rotates 360° around the cross-section of the arc spherical shell 7 driven by the connecting rod 2 and can be adjusted in any direction to reduce the influence of the hollow cone angle on the spray profile, and to ensure that spraying can be carried out in every direction in the pipeline as much as possible, thereby improving the uniformity of spraying.

[0034] Furthermore, in order to avoid clogging of the circular hole 14, a silicone protective sleeve 9 is provided on the lower part of the conical shell; a cover shell 16 for covering the motor is provided above the fixed jacket 5, and the cover shell is connected and fixed to the fixed jacket 5 by connecting screws 12; the rotating shaft 11 extending into the water inlet pipe is water-tightly sleeved with the water inlet pipe 3.

[0035] The installation process is that the first end of a connecting rod is welded and fixed to the inner circumference of the conical shell 8 in advance, and the second end of the connecting rod is connected to the rotating shaft with rotating blades fixedly installed at the lower end by screws or buckles, and then the arc spherical shell 7 is inserted into the conical shell 8, and then the upper end of the wear-resistant pipe sleeve 6 is buckled (or screwed) on the opening 17 of the fixed jacket 5, and then the integrated component of the conical shell 8, the arc spherical shell 7, the connecting rod and the rotating shaft is inserted into the water inlet pipe 3 from bottom to top, the upper end of the rotating shaft passes through the fixed jacket 5 and is fixedly connected to the output end of the motor, and finally the arc spherical shell 7 is locked and fixed to the outer peripheral wall of the wear-resistant pipe sleeve 6 by screws.

[0036] The conical shell sleeve 8 is made of stainless steel, which has the characteristics of corrosion resistance, oxidation resistance, and high hardness. It can effectively avoid the influence of disinfectants on the nozzle structure, is not easy to rust and deform, and effectively extends the use time of the nozzle; the wear-resistant pipe sleeve 6 is made of clad bamboo plywood material covered on the outer shell stainless steel material. The clad bamboo plywood has the characteristics of waterproof, acid and alkali resistance, etc. The conical structure of the conical shell sleeve 8 reduces the space at the water outlet, helps to increase the water pressure, and makes the water flow form droplets with smaller diameter as much as possible when spraying out at the nozzle outlet.

[0037] The conical shell 8 is provided with a silicone protective cover 9. The silicone protective cover 9 is removed when the nozzle is working, and is put on the outer surface of the conical shell 8 when the nozzle is not in use to prevent dust, bacteria and other substances in the air from entering the inside of the nozzle or covering the small holes and gaps at the nozzle mouth, which are difficult to clean and affect the disinfection and sterilization effect of the disinfectant passing through the nozzle. The silicone protective cover 9 has unique high elasticity and waterproofness and integrity and has excellent metal bonding force. It can be tightly attached to the metal surface, is resistant to high and low temperatures, has good anti-aging and impact resistance, and has good anti-rust and anti-corrosion effects.

[0039] Furthermore, a silicone protective cover is provided on the lower part of the conical shell. The silicone protective cover is removed when the conical shell is spraying water, and is put on when the conical shell is not in use.

[0040] The centrifugal rotating nozzle for pipeline disinfection of the present invention drives the liquid in the cavity to rotate with the rotating blades made of wear-resistant material, and after a certain centrifugal force is generated, the liquid is sprayed out from the outlet, thereby eliminating the step of the fluid passing through the booster pipe and reducing the size of the nozzle. After the booster pipe is removed, the conical shell (nozzle) is no longer restricted by direction, and the conical shell nozzle end and the water inlet of the wear-resistant pipe sleeve are connected by an arc spherical shell, so that the conical shell spray can be rotated 360 degrees in all directions without dead angles.
