Description

Technical Field

[0001] This utility model relates to the field of spray tower technology, specifically to a rotary spray head for spray towers. Background Technology

[0002] A spray tower, also known as a scrubbing tower or water scrubbing tower, is a device that purifies waste gas through gas-liquid contact. The core principle of a spray tower is to utilize the full contact between the liquid and the waste gas, removing pollutants through dissolution, absorption, or chemical reaction, thereby purifying the air. Spray towers are widely used in the chemical, metallurgical, and electroplating industries.

[0003] The spray tower operates through horizontally passing spray rods and several spray nozzles. In practical applications, because the coverage area of ​​the spray rods within the cylindrical spray tower is relatively small, additional nozzles are typically added to expand the coverage area. Furthermore, the nozzles can be angled to further expand the coverage area. However, more nozzles will increase water consumption, and overlapping coverage areas will waste water. In addition, the nozzle tips are small, allowing unfiltered micro-impurities in the water to gradually adhere and accumulate within the nozzles, affecting their permeability and further impacting the spraying effect. Therefore, there is room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problems, namely, the limitations of fixed nozzles and the fact that the nozzle tip is small and easily clogged by incompletely filtered micro-impurities, by providing a rotary spray head for spray towers.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a rotary spray head for a spray tower, comprising a nozzle body; a connecting rod is provided at the upper end of the nozzle body, and an adjusting plate is provided at the upper end of the connecting rod; further comprising:

[0006] An angle adjustment assembly; connected to an adjustment plate, including a mounting bracket and an inner frame; the inner frame is rotatably connected to the inside of the mounting bracket; the adjustment plate is rotatably connected to the inside of the inner frame; the mounting bracket is provided with a plurality of electric push rods, the output ends of which all extend out of the mounting bracket and are rotatably connected to the adjustment plate;

[0007] The material collection assembly includes a filter cone housed within a nozzle body, wherein a stepped material receiving groove is provided at the lower end of the nozzle body, and the lower end of the filter cone is connected to the innermost material receiving groove.

[0008] The conduit is connected to the nozzle body near the upper end, and the upper end of the conduit is connected to the spray bar.

[0009] Furthermore, both sides of the inner frame are provided with short shafts, and both sides of the mounting bracket are provided with through holes that can be rotatably connected to the short shafts; both the front and rear sides of the connecting support rod are provided with long shafts, and both the front and rear sides of the inner frame are provided with through holes that can be rotatably connected to the long shafts.

[0010] Furthermore, the upper end of the electric push rod is connected to an assembly plate, and the assembly plate is evenly distributed with a number of assembly holes.

[0011] Furthermore, each of the electric push rods is provided with a universal ball at its lower end, and the adjustment plate is provided with several bases, each of which is provided with a spherical groove at its upper end that can be rotatably connected to the universal ball.

[0012] Furthermore, the filter cone is a cone-shaped structure formed by bending a metal mesh, with its upper end sealed.

[0013] Furthermore, the lower end of the nozzle body is provided with several extended shoulders, the inner diameter of which decreases progressively; the receiving groove is located on the upper end face of each extended shoulder.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] Driven by multiple electric push rods at different positions and corresponding angle adjustment components, the nozzle body can be rotated and adjusted at various angles. By presetting the drive time interval of each electric push rod, the nozzle body can be rotated and used, thereby expanding the coverage area of ​​the nozzle body and reducing the number of unnecessary nozzles.

[0016] It is equipped with a stepped receiving trough and a filter cone, which can directly guide tiny impurities in the water source into the filter cone, avoiding clogging of the relatively small end of the nozzle body. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1, in conjunction with Appendix Figure 1 A rotary spray head for a spray tower includes a nozzle body 1; a connecting rod 2 is provided at the upper end of the nozzle body 1, and an adjusting plate 3 is provided at the upper end of the connecting rod 2.

[0024] Combined with appendix Figure 1 , 2 It also includes an angle adjustment component; connected to the adjustment plate 3, it includes a mounting frame 4 and an inner frame 5; the inner frame 5 is rotatably connected to the inside of the mounting frame 4; the adjustment plate 3 is rotatably connected to the inside of the inner frame 5; that is, the adjustment plate 3 can tilt in all directions within the mounting frame 4 and the inner frame 5.

[0025] Specifically, the inner frame 5 has short shafts 7 on both sides, and the mounting bracket 4 has through holes on both sides that can be rotatably connected to the short shafts 7; the connecting rod 2 has long shafts 8 on both the front and rear sides, and the inner frame 5 has through holes 8 on both the front and rear sides that can be rotatably connected to the long shafts 8; in the above structure, the inner frame 5 can rotate in the front-rear direction within the mounting bracket 4, while the adjusting plate 3 can rotate in the left-right direction within the inner frame 5; in summary, multi-directional tilt adjustment of the adjusting plate 3 can be achieved.

[0026] Based on the above structure, the mounting frame 4 is also provided with several electric push rods 6. The upper ends of the electric push rods 6 are connected to the assembly plate 12, and the assembly plate 12 is provided with several assembly holes evenly distributed. The electric push rods 6 are used to apply force. The rotation operation of the adjustment plate 3 can be realized by presetting the operation sequence and time interval of each adjacent electric push rod 6 through the external control board.

[0027] The output end of each electric push rod 6 extends out to a mounting bracket 4 and is rotatably connected to the adjustment plate 3. Specifically, each electric push rod 6 has a universal ball 13 at its lower end, and the adjustment plate 3 has several bases 14. Each base 14 has a spherical groove at its upper end that can rotatably connect with the universal ball 13. When the electric push rod 6 applies force, the adjustment plate 3 will tilt. At this time, the universal ball 13 rotates within the base 14 to cooperate and avoid affecting the rotation adjustment of the adjustment plate 3 and the nozzle body 1.

[0028] Combined with appendix Figure 3 It also includes a material collection assembly; including a filter cone 9 provided inside the nozzle body 1, and a stepped material receiving groove 10 provided at the lower end of the nozzle body 1, with the lower end of the filter cone 9 connected to the innermost material receiving groove 10.

[0029] Specifically, the filter cone 9 is a cone-shaped structure formed by bending metal mesh, with its upper end sealed to prevent the spray liquid from passing directly through the inside; the lower end of the nozzle body 1 is provided with several extended shoulders 15, with the inner diameter of the extended shoulders 15 decreasing; the receiving troughs 10 are located on the upper end face of each extended shoulder 15, so that when the spray liquid enters the nozzle body 1, the liquid passes through the filter cone 9 and is sprayed out from the lower end of the nozzle body 1, while impurities remain on the outside of the filter cone 9 and fall down its outer side into the receiving trough 10 for collection;

[0030] Combined with appendix Figure 1 It also includes a conduit 11; the conduit 11 is connected to the nozzle body 1 near the upper end, and the upper end of the conduit 11 is connected to the spray rod for introducing spray liquid. The soft material avoids affecting the rotation adjustment of the nozzle body 1.
