Detailed Description
The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 4, an anti-blocking cleaning device for a denitration spray gun comprises a pipeline 2, wherein a cleaning structure 1 is arranged in the pipeline 2, the cleaning structure 1 comprises a rotating frame 11, a connecting piece 12 and a rotating roller 13, the rotating roller 13 is of a spiral line structure, the rotating roller 13 of the spiral line structure plays a limiting role on a blocking object in the pipeline 2 in the rotating process, the blocking object is stirred by the rotating roller 13 of the spiral line structure under the condition that the blocking object cannot displace, after being stirred, the volume is reduced, and the blocking object can pass through a place where the original volume cannot pass through, so that the blocking object can be discharged out of the pipeline along with the progress of an injection procedure.
In the embodiment, two ends of the pipeline 2 are respectively communicated with the storage box 3 and the spray gun, so that the spray gun is communicated with the storage box 3, and the spray gun is ensured to be capable of normally injecting liquid.
The diameter of the outer diameter of the rotating roller 13 is smaller than the diameter of the water outlet of the pipeline 2, and the rotating roller 13 is positioned in the pipeline 2 and needs to rotate, so that the rotating roller 13 is prevented from contacting with the inner wall of the pipeline 2, and the rotating roller 13 always rubs with the pipeline 2 when the rotating roller 13 rotates, so that the rotating roller 13 or the inner wall of the pipeline 2 is damaged due to mutual friction, and the service life is reduced.
In this embodiment, the rotating roller 13 is preferably made of an elastic material such as a spring, and since ammonia reacts with many metal materials, the elastic material constituting the rotating roller 13 is preferably made of an elastic plastic.
The rotating roller 13 extends out of the pipeline, so that a worker can drive the rotating roller 13 to rotate through the rotating frame 11, and can shake the rotating roller 13 by swinging the extending part of the rotating roller 13, and the rotating roller 13 is matched with the inner wall of the pipeline 2 in the shaking process to cut up the blockage, so that another cleaning scheme is realized. The connecting piece 12 is fixedly connected with the pipeline 2, the rotating frame 11 is rotatably connected with the connecting piece 12, and the rotating roller 13 is linked with the rotating frame 11.
The spiral center of the rotating roller 13 is concentrically arranged with the circle center of the pipeline 2, so that eccentric rotation phenomenon is avoided when the rotating roller 13 is linked with the rotating frame 11, unnecessary friction between the rotating roller 13 and the pipeline 2 is generated, and the service life of the embodiment is prolonged.
As shown in fig. 5, the end surface of the rotating frame 11, which is close to the connecting piece 12, is provided with a limiting groove 111 for embedding the connecting piece 12, the limiting groove 111 has a trapezoid structure, and the length of one end of the limiting groove 111, which is close to the connecting piece 12, is smaller than the length of one end of the limiting groove 111, which is far away from the connecting piece 12. The limiting groove 111 is narrow at the upper part and wide at the lower part, and the connecting piece 12 is limited in the limiting groove 111 after being embedded in the limiting groove 111, and the rotating frame 11 is connected with the pipeline 2 in the connecting mode, so that the rotating frame 11 is prevented from being separated from the pipeline 2. Meanwhile, the degree of freedom of the rotating direction of the rotating frame 11 is not limited by the limiting mode, so that the rotating frame 11 can still rotate.
In a general injection procedure, the principle of diameter reduction is used: the flow is equal to the flow velocity multiplied by the sectional area, the area is reduced, and the flow velocity is increased. The water outlet is smaller than the pipe body for transmitting the ammonia water, and the flow rate of the ammonia water is increased by reducing the area of the water outlet under the condition of unchanged water pressure, so that the injection efficiency is improved. Therefore, in order to avoid interference between the rotating roller 13 and the water outlet with reduced area, the diameter of one end of the rotating roller 13 close to the water outlet of the pipeline 2 is smaller than that of one end of the rotating roller 13 far away from the water outlet of the pipeline 2, i.e. one end of the rotating roller 13 close to the water outlet of the pipeline 2 is in a taper structure. The taper ratio of the rotating roller 13 is determined according to the actual need of the pipeline 2 which is matched with the rotating roller.
Meanwhile, due to the fact that the diameter reduction principle is adopted, the inner structure of the pipeline 2 or the spray gun is mostly changed from wide to narrow, and due to the fact that the area is reduced, the pipeline 2 or the spray gun is more prone to being blocked, and the blocking situation is more serious as the pipeline 2 serving as a water outlet is closer to the water outlet. The pitch of one end of the rotating roller 13 close to the water outlet of the pipeline 2 is smaller than that of one end of the rotating roller 13 far away from the water outlet of the pipeline 2, so that the parts of the rotating roller 13 close to the water outlet of the pipeline 2 participating in the crushing work are increased, the adjacent distance of each crushing part is shortened, and the crushing efficiency is improved.
At the end of the injection process, the present embodiment is located in the production environment, so that there may be a metal factor in the air in the environment that can react with the ammonia water to generate a precipitate, and in order to avoid the reaction phenomenon, an anti-stacking surface 21 for preventing the accumulation of the cleaning object is disposed at the end of the pipe 2 away from the storage tank 3, i.e. at the water outlet, the anti-stacking surface 21 has an arc structure, and the residual ammonia water is guided to slide into the pipe 2 again according to the structure of the anti-stacking surface 21. The pile-preventing surface 21 extends all the way into a spray gun which is later mounted at the water outlet of the pipe 2.
Based on the above embodiment, another embodiment is provided, as shown in fig. 6 and 7, a recovery tank 31 for recovering the cleaning object cleaned by the cleaning structure 1 is provided, and a filter screen 32 for filtering the cleaning object is provided in the recovery tank 31. Preferably, the recovery tank 31 is provided on the storage tank 3, the recovery tank 31 communicates with the storage tank 3, and the filter screen 32 is provided between the recovery tank 31 and the storage tank 3.
When the cleaning procedure is performed, the water outlet can be aligned to the recovery box 31, the recovery box 31 is communicated with the storage box 3, a filter screen 32 for filtering cleaning objects is arranged between the storage box 3 and the recovery box 31, the blocking objects are isolated by the filter screen 32 when ammonia water is brought out, the ammonia water enters the storage box again after being filtered, and the recovery of the ammonia water discharged together due to the cleaning of the blocking objects is realized, so that the economic benefit is improved.
Meanwhile, the edges of the rotating frame 11 are all inclined planes, so that the situation that workers scratch the rotating frame 11 at an acute angle on the rotating frame 11 to cause safety accidents is avoided.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
