[0003] The recyclable spraying device uses the spray head as the core component to achieve efficient spraying and resource recycling. Relying on various working principles, compatible materials and spray characteristics, it can be precisely adapted to different scenario requirements: for example, the solid cone spray head and spiral spray head made of PP material are used. Through the internal flow channel design, the spray liquid can form a solid cone spray with a wide coverage or a spiral spray with good atomization effect under pressure, which can expand the gas-liquid contact area.

[0004] The spray heads used in circulating spray devices have the following defects. For example, in the spray heads of circulating spray devices used for water conservation in papermaking, residual pulp fibers and impurities accumulate in the circulating spray water, causing blockage in the flow channel of the spray head and affecting the circulation effect. To address this issue, an anti-clogging structure for the spray heads of circulating spray devices is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging structure for the spray head of a recirculating spray device, which aims to improve the problem of residual pulp fibers and impurities accumulating in the recirculating spray water of existing technologies, such as the spray head of a water-saving recirculating spray device for papermaking.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a spray head anti-clogging structure for a recirculating spray device, comprising a spray pipe and an installation head. The installation head is snapped into the bottom inner wall of the spray pipe, and a spray head is fixedly connected to the bottom outer wall of the installation head. An inner cavity is formed on the side inner wall of the spray pipe. A dispensing mechanism is provided on the spray pipe, and an auxiliary mechanism is provided on the installation head. The dispensing mechanism includes a fixing frame, which is fixedly connected to the side inner wall of the inner cavity. A filter screen is snapped into the top inner wall of the fixing frame. An installation plate is threadedly fixed to the top inner wall of the spray pipe. A water injection pipe is fixedly connected to the top inner wall of the installation plate. A movable stopper is slidably connected to the side outer wall of the water injection pipe. A bearing plate is rotatably connected to the bottom outer wall of the movable stopper. A screw brush is fixedly connected to the bottom outer wall of the bearing plate. A telescopic rod is fixedly connected to the bottom outer wall of the installation plate. A compression spring is fixedly connected to the side outer wall of the telescopic rod. Impurity outlets are formed on the left and right outer walls of the spray pipe.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a threaded groove, which is formed on the outer side wall of the mounting plate. A directional mark is formed on the top outer wall of the mounting plate. A through hole is formed on the inner front wall of the mounting head. A threaded rod is threadedly connected to the inner front wall of the through hole. An adjustment plate is fixedly connected to the front end of the threaded rod.

[0008] As a further description of the above technical solution: the water injection pipe penetrates the bottom outer wall of the mounting plate, and the water injection pipe is connected to the filter screen.

[0009] As a further description of the above technical solution: the propeller brush contacts the top outer wall of the filter screen, and the telescopic rod contacts the top outer wall of the movable stopper disc.

[0010] As a further description of the above technical solution: the outlet is connected to the filter screen, and there are four telescopic rods, which are respectively fixedly installed in a ring on the bottom outer wall of the mounting plate.

[0011] As a further description of the above technical solution: the outer diameter of the movable plug disc is adapted to the inner diameter of the inner cavity, and there are a number of screw brushes, which are fixedly connected in a ring to the bottom outer wall of the bearing disc.

[0012] As a further description of the above technical solution: the threaded groove is threadedly connected to the top inner wall of the spray pipe, and the top outer wall of the pointing mark is fixedly connected with a display coating.

[0013] As a further description of the above technical solution: there are two directional marks, which are respectively opened on the outer side wall of the adjustment plate and the mounting plate.

[0014] As a further description of the above technical solution: the threaded rod is threadedly connected to the inner wall of the front side of the spray pipe, and the threaded rod is threadedly connected to the inner wall of the inner ring of the through hole.

[0015] As a further description of the above technical solution: the outer side wall of the adjustment disc is provided with a groove, and a frosted pad is fixedly connected to the outer side wall of the groove.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting a filter screen inside the spray pipe, impurities in the incoming water can be effectively filtered, preventing impurities from entering the spray head with the water flow and causing blockage. At the same time, the water flow can drive the screw brush to rotate, continuously washing the surface of the filter screen and preventing impurities from sticking to the filter screen and reducing filtration efficiency. When a large amount of impurities accumulate, the water pressure in the water injection pipe will push the movable plug to move, allowing the accumulated impurities to be discharged through the impurity outlet. After the water pressure returns to normal, the compression spring can drive the movable plug to reset and close the impurity outlet. The entire anti-clogging process does not require additional power, relying on the water flow itself and the structural cooperation to achieve automatic anti-clogging and impurity discharge, effectively ensuring the continuous and stable operation of the spray device and reducing spray failures caused by blockage.

[0017] 2. In this utility model, the installation head and the spray pipe are fixed by a threaded rod and an adjusting plate. Rotating the adjusting plate allows the threaded rod to separate from the through hole, facilitating quick replacement and maintenance of the spray head. The installation plate and the spray pipe are connected by threads, and rotating the installation plate allows it to be separated from the spray pipe, making it easy to remove the entire dispensing mechanism for inspection, cleaning, or repair. At the same time, the pointing marks and display coating help operators quickly align the installation position, and the grooves and frosted pads on the adjusting plate increase friction during operation, preventing slippage, improving the convenience of maintenance operations, reducing maintenance difficulty, and further enhancing the practicality of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3 This utility model provides an embodiment of a spray head anti-clogging structure for a recirculating spray device, comprising a spray pipe 1 and a mounting head 2. The mounting head 2 is snapped onto the bottom inner wall of the spray pipe 1, and a spray head 3 is fixedly connected to the bottom outer wall of the mounting head 2. An inner cavity 4 is formed on the side inner wall of the spray pipe 1. An adjustment mechanism 5 is provided on the spray pipe 1, and an auxiliary mechanism 6 is provided on the mounting head 2. The adjustment mechanism 5 includes a fixing frame 51, which is fixedly connected to the side inner wall of the inner cavity 4. A filter screen 52 is snapped onto the top inner wall of the fixing frame 51. The filter screen 52 can filter impurities in the water entering the spray pipe 1, preventing impurities from entering the spray head 3 with the water flow and causing blockage. An mounting plate 53 is threadedly fixed to the top inner wall of the spray pipe 1, and a water injection pipe 54 is fixedly connected to the top inner wall of the mounting plate 53. A movable stopper disc 55 is slidably connected to the outer side wall of the water injection pipe 54. A bearing disc 56 is rotatably connected to the outer bottom wall of the movable stopper disc 55. A screw brush 57 is fixedly connected to the outer bottom wall of the bearing disc 56. The screw brush 57 rotates under the push of water flow, which can wash the outer top wall of the filter screen 52 to prevent impurities from sticking to the filter screen 52 and causing a decrease in filtration efficiency. A telescopic rod 58 is fixedly connected to the outer bottom wall of the mounting plate 53. A compression spring 59 is fixedly connected to the outer side wall of the telescopic rod 58. The outer walls on the left and right sides of the spray pipe 1 are provided with impurity outlets 510. The impurity outlets 510 are channels for discharging impurities between the filter screen 52 and the movable stopper disc 55. When there are many impurities, the water pressure increases and the movable stopper disc 55 moves, the impurities can be discharged through the impurity outlets 510 to avoid blockage.

[0022] Reference Figures 2-4 The water injection pipe 54 penetrates the bottom outer wall of the mounting plate 53 and is connected to the filter screen 52. The screw brush 57 contacts the top outer wall of the filter screen 52, and the telescopic rod 58 contacts the top outer wall of the movable stopper plate 55. The waste outlet 510 is connected to the filter screen 52. There are four telescopic rods 58 in total. The four telescopic rods 58 are respectively fixedly installed in a ring on the bottom outer wall of the mounting plate 53. The four ring-distributed telescopic rods 58 can support and guide the movable stopper plate 55 from multiple directions, further ensuring the stability of the movable stopper plate 55 when it moves and preventing it from tilting. The outer diameter of the movable stopper plate 55 is adapted to the inner diameter of the inner cavity 4. There are several screw brushes 57 in total. Several screw brushes 57 are fixedly connected in a ring on the bottom outer wall of the bearing plate 56.

[0023] Reference Figures 3-4 The auxiliary mechanism 6 includes a threaded groove 61, which is formed on the outer side wall of the mounting plate 53. A directional mark 62 is formed on the top outer wall of the mounting plate 53. The directional mark 62 facilitates the operator's quick alignment of the mounting plate 53 with the spray pipe 1, improving installation efficiency and facilitating the determination of the rotation angle of the mounting plate 53. A through hole 63 is formed on the inner front wall of the mounting head 2. A threaded rod 64 is threadedly connected to the inner front wall of the through hole 63. An adjusting disc 65 is fixedly connected to the front end of the threaded rod 64. The threaded groove 61 is threadedly connected to the inner top wall of the spray pipe 1. A display coating is fixedly connected to the outer top wall of the directional mark 62, enhancing the appearance of the directional mark 62. The high visibility of the indicator 62 ensures that operators can clearly see the indicator 62 under different lighting conditions, improving operational convenience. There are two indicator 62s, which are respectively located on the outer side walls of the adjustment plate 65 and the mounting plate 53. The threaded rod 64 is threaded to the inner front wall of the spray pipe 1 and the inner ring of the through hole 63. The outer side wall of the adjustment plate 65 has a groove, which increases the friction between the adjustment plate 65 and the operator's hand. A frosted pad is fixedly connected to the outer side wall of the groove, which further increases the friction and improves the feel when the operator rotates the adjustment plate 65, making the operation smoother.

[0024] Working principle: When water is injected through the water inlet pipe 54, impurities in the water are filtered through the filter screen 52, and then sprayed out through the spray head 3. As the water passes through the filter screen 52, the water flow drives the screw brush 57 to rotate, allowing the screw brush 57 to make contact with and wash the surface of the filter screen 52, preventing impurities from sticking to the filter screen 52. When there are many impurities, the water flow through the filter screen 52 decreases, increasing the water pressure in the water inlet pipe 54. This causes the movable stopper 55 to move backward, compressing the spring 59. After moving to a certain position, it releases... The outlet 510 is exposed, allowing impurities between the filter screen 52 and the movable plug 55 to be ejected through the outlet 510. After the filter screen 52 returns to normal filtration water pressure, the compression spring 59 returns the movable plug 55 to its original position according to the water pressure change. At the same time, when the internal components need maintenance, the threaded rod 64 rotates when the adjustment disc 65 is rotated. The threaded rod 64 rotates and separates from the through hole 63, making it easy to replace and maintain the spray head 3. At the same time, rotating the mounting disc 53 separates it from the top of the spray pipe 1, making it easy to remove and maintain the adjustment mechanism 5.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
