Description

Technical Field

[0001] This utility model relates to the field of washing tower technology, specifically to a washing tower anti-clogging spray device. Background Technology

[0002] A scrubbing tower is a new type of gas purification equipment. It is an improvement on the floating packing layer gas purifier and is widely used in the pretreatment of industrial waste gas purification and dust removal. It has a very good purification effect. The spray device is one of the core components of the scrubbing tower. It mainly consists of spray pipes, spray heads and nozzles. The spray liquid (usually water or a specific chemical solution) is sprayed into the waste gas in the form of mist or small droplets through the spray pipes and spray heads.

[0003] For example, the announcement number CN214075932U is a monitoring device for preventing blockage of the spray pipe of a washing tower. The device includes a shell, with an inlet and an outlet at the upper and lower ends of the shell, respectively. A rotary turbine is installed in the shell, and a connecting shaft is installed on the rotary turbine. An externally observable rotating wheel is coaxially connected to the rotary turbine. When the spray liquid flows through the rotary turbine, the rotating wheel rotates simultaneously, directly reflecting the flow of the spray liquid in the circulating pipe.

[0004] During the use of the above-mentioned device, the spray system inside the washing tower is equipped with spray heads. The surface of the spray heads usually has several holes to discharge liquid. Long-term liquid discharge will cause crystals to form on the surface of the holes and cause blockage, thereby reducing the spraying effect and causing pump blockage, motor burnout, etc. Therefore, we propose a washing tower anti-clogging spray device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a scrubbing tower anti-clogging spray device to solve the problem mentioned in the background art that the surface of the spray head usually has several holes to discharge liquid. Long-term liquid discharge will cause crystallization on the surface of the holes and cause blockage, thereby reducing the spraying effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scrubbing tower anti-clogging spray device, comprising a tower body;

[0007] Also includes:

[0008] A conveying pipe is installed around the outside of the tower body. A ring of evenly distributed spray heads is installed around the inner wall of the tower body, arranged in a circular array. The spray heads are connected to the conveying pipe via a connecting pipe that passes through the surface of the tower body. The front surface of each spray head has several evenly arranged water outlets that connect to the interior of the spray head. A top plate is installed on the outside of the connecting pipe and is movably engaged with the outside of the connecting pipe. A cleaning needle is installed on the side of the top plate near the spray head, with the number and position of the cleaning needles corresponding to the number and position of the water outlets. The bottom of the cleaning needle extends through a circular hole at the rear end of the spray head into the interior of the spray head, and the bottom of the cleaning needle is movably engaged with the interior of the water outlet.

[0009] Preferably, a limiting plate is fixedly installed on the outer side of the connecting tube, and the ejector plate is movably fitted below the limiting plate. A push plate is movably engaged on the outer side of the connecting tube, and the push plate is located above the limiting plate. The push plate and the ejector plate are fixedly connected by a connecting rod. A spring is provided between the push plate and the limiting plate, and the spring is sleeved on the outer side of the connecting tube.

[0010] Preferably, a brush is provided at the bottom of the unblocking needle on the outside of the inside of the spray head.

[0011] Preferably, a rotating ring is installed inside the tower body, a connecting frame is installed on one side of the inner wall of the rotating ring, a rotating rod is installed on the front end of the connecting frame, and a roller is installed on the outer side of the rotating rod. The roller moves along the inner wall of the tower body by rotating the rotating ring, and the roller contacts the outer side of the push plate.

[0012] Preferably, a fixing ring is installed on the inner wall of the tower body. The fixing ring is located on one side of a plurality of spray heads, and the rotating ring is movably engaged with the inner wall of the fixing ring. A second through groove is provided on the inner wall surface of the fixing ring, and the connecting frame is slidably engaged with the inside of the second through groove.

[0013] Preferably, the fixed ring has a first through groove on the surface of the end near the spray head, and the rotating ring has a plurality of evenly distributed teeth on the surface of the end near the spray head, with the teeth extending out of the fixed ring from the first through groove. A rotating gear is installed on one side of the inner wall of the tower body, and the rotating gear is meshed with the teeth for transmission. The rotating gear is driven by an external motor to drive the rotating ring to rotate along the axis of the tower body inside the fixed ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) Several spray heads are installed inside the tower body. A connecting pipe is set at the rear end of the spray head. The other end of the connecting pipe is connected to the conveying pipe. The conveying pipe delivers liquid to the spray head through an external water tank and water pump. A top plate is set on the outside of the connecting pipe. Several unclogging needles are set at the bottom of the top plate. The unclogging needles are aligned with the holes on the surface of the spray head. A push plate is set on the outside of the top plate. A spring is set between the top plate and the limit plate to support the top plate. When it is necessary to unclog the holes, the push plate is pushed towards the spray head by pressing the top plate, thereby driving the unclogging needles to be inserted into the holes to unclog them. A brush is set at the front end of the unclogging needles. The brush can further unclog the crystals and impurities on the surface of the holes. After pressing down, the top plate is reset under the action of the spring, so that the surface of the holes can be unclogged quickly, which improves efficiency.

[0016] (2) By installing a fixed ring inside the tower body, and setting a rotating ring inside the fixed ring, the upper end of the rotating ring is provided with teeth and extends from the top of the fixed ring through the first through groove. A rotating gear is installed on one side inside the tower body. The rotating gear is meshed with the teeth for transmission. The motor drives the rotating gear to rotate. The rotating ring rotates slowly through the transmission. A roller structure is set on the inner side of the rotating ring. The roller moves along the inner wall of the tower body through the rotation of the rotating ring. When the roller passes one side of a push plate, it will squeeze the push plate, causing the push plate to extend and retract towards the spray head, thereby clearing the hole with the unblocking needle.
