Description

Technical Field

[0001] The utility model relates to the technical field of granulation, and particularly relates to a spraying device. Background Art

[0002] A spraying and sedimentation device for polyacrylamide granulation provided in Chinese Patent Publication No. CN209392963U includes a base, a cyclone dust collector, a connecting pipe, a sedimentation chamber and a water pump. Two ends of the top of the base are respectively fixedly connected with a cyclone dust collector and a water tank. A sedimentation chamber is arranged between the cyclone dust collector and the water tank on the top of the base. The exhaust port of the cyclone dust collector is connected to the sedimentation chamber. A water pump is installed on the top of the water tank. The water inlet end of the water pump is communicated with the inside of the water tank. The water outlet end of the water pump is connected with a connecting pipe. The end of the connecting pipe is connected to the sedimentation chamber. The sedimentation chamber includes an exhaust cylinder, a sedimentation tank, a tank cover, a partition board, a sieve mesh, a first filter screen, a second filter screen, a drying layer and a spray head. This gas dust removal device for polyacrylamide production filters the gas by sequentially passing through the first filter screen with a larger pore diameter and the second filter screen with a smaller pore diameter in the sedimentation tank, which is convenient for better removing polyacrylamide particles in the gas.

[0003] In actual use, the sieve mesh does not have a cleaning mechanism, so the sieve mesh will be blocked after long-term use. At the same time, the sprayed water is directly discharged externally and cannot be recycled, resulting in waste of water resources.

[0004] Therefore, a spraying device is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems that in actual use, the sieve mesh does not have a cleaning mechanism, so the sieve mesh will be blocked after long-term use, and at the same time, the sprayed water is directly discharged externally and cannot be recycled, resulting in waste of water resources. The utility model provides a spraying device.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A spraying device includes a box body. A filter plate is fixedly installed on the inner side wall of the box body. A plurality of atomizing spray heads are fixedly installed on the inner top of the box body and are arranged in a rectangular array. A water injection pipe is fixedly installed on the top of the box body. The water outlet end of the water injection pipe extends into the box body and is fixedly connected to the water inlet end of the atomizing spray head. A smoke injection pipe is fixedly installed on one side wall of the box body above the filter plate. A cleaning mechanism is arranged on the top of the filter plate. A sprayed water filtering mechanism is arranged on the inner side wall of the box body below the filter plate. A gas drying mechanism is arranged at the interval between the filter plate and the sprayed water filtering mechanism;

[0008] Specifically, in some embodiments, when it is necessary to treat the flue gas generated by granulation, the injection pipe is preferentially externally connected to the exhaust end of the cyclone filter. At this time, the flue gas enters the interior of the box body, and the water injection pipe injects water into the atomizing nozzle, causing the atomizing nozzle to spray the interior of the box body. At the same time, the filter plate filters the humidified flue gas. During the operation, the cleaning mechanism starts to brush the filter plate, and the flue gas after receiving spraying and filtering enters the gas drying mechanism for drying treatment.

[0009] Further, the cleaning mechanism includes a brush, a chute, a slider, a threaded rod, a first gear, a second gear, a connecting rod, a double-shaft motor, and a fixing block. The front and rear inner walls of the box body are provided with chutes. The threaded rod is rotatably installed on the inner walls on both sides of the chute. The slider is arranged in the chute and sleeved on the threaded rod and is threadedly connected to the threaded rod. A brush is fixedly installed on the corresponding side wall of the slider, and the brush is attached to the top of the filter plate. The threaded rod horizontally penetrates through the chute and extends to the outside of one side wall of the box body. A first gear is fixedly installed at one end of the threaded rod located outside the box body. A double-shaft motor is fixedly installed on one side wall of the box body. A connecting rod is fixedly installed at the output end of the double-shaft motor. A second gear meshing with the first gear is fixedly installed at the free end of the connecting rod.

[0010] Specifically, the double-shaft motor drives the connecting rod and the second gear to rotate. At this time, the first gear rotates with the threaded rod. At this time, the slider drives the brush to move horizontally to brush the filter plate.

[0011] Further, a fixing block is fixedly installed on one side wall of the box body. The number of fixing blocks is two groups and they are sequentially located in front of and behind the double-shaft motor. The fixing block is sleeved on the connecting rod and is slidably connected to the connecting rod. Specifically, the fixing block can effectively limit the position of the connecting rod to prevent the first gear and the second gear from disengaging.

[0012] Further, smoke distribution pipes are fixedly installed on the inner walls on both sides of the box body above the filter plate. The number of smoke distribution pipes is three groups and they are arranged at equal intervals. Smoke exhaust holes are provided on the outer side wall of the smoke distribution pipe, and the smoke exhaust holes are located on the front and rear side walls of the smoke distribution pipe. The smoke distribution pipe horizontally penetrates through the box body and is fixedly connected to the injection pipe. Specifically, the smoke distribution pipe can effectively disperse the flue gas evenly and effectively ensure the combination of the flue gas and the water mist.

[0013] Furthermore, the spray water filtering mechanism includes a water collecting cover, a guide plate, a tube filter, a circulation pump, a return pipe and a stop valve. The inner side wall of the box body is fixedly installed with a water collecting cover, which is arranged in a funnel-shaped structure. The bottom of the water collecting cover is fixedly installed with an installation pipe, and the bottom of the installation pipe is fixedly installed with a tube filter. A circulation pump is fixedly installed on one side wall of the box body. The water pumping end of the circulation pump is fixedly connected to the water outlet end of the tube filter through a pipeline horizontally penetrating the box body. The water drainage end of the circulation pump is fixedly installed with a return pipe, and the free end of the return pipe is fixedly connected to the water injection pipe. A stop valve is fixedly installed on the return pipe;

[0014] Specifically, the water collecting cover collects the spray water. By starting the circulation pump, the spray water enters the tube filter for filtering operation. At this time, the filtered spray water enters the water injection pipe through the return pipe for recycling.

[0015] Furthermore, a guide plate is fixedly installed on the inner bottom of the water collecting cover, which is arranged in an inclined structure. The number of tube filters is four groups and they are connected. The built-in filters of the four groups of tube filters are PP melt-blown filter elements, wound filter elements, microporous membrane folded filter elements and activated carbon filter elements in sequence, and the filtration accuracy of the filter elements is 0.11um.

[0016] Furthermore, the gas drying mechanism includes an exhaust pipe, an air extraction pump, a connecting pipe and a drying box. An exhaust pipe, an air extraction pump and a drying box are fixedly installed on one side wall of the box body in sequence. The exhaust pipe horizontally penetrates the box body and is communicated with the box body. The air extraction end of the air extraction pump is fixedly connected to the free end of the exhaust pipe. The air exhaust end of the air extraction pump is fixedly installed with a connecting pipe, and the free end of the connecting pipe is fixedly connected to the drying box. An air outlet pipe is fixedly installed at the bottom of the drying box. A number of stacked activated carbon filter plates are arranged in the drying box;

[0017] Specifically, the flue gas is extracted by the air extraction pump and input into the drying box, and the activated carbon filter plate performs the water absorption and drying operation on the flue gas.

[0018] The beneficial effects of the present utility model are as follows:

[0019] By setting the cleaning mechanism, the present utility model can effectively brush the filter plate, avoiding the situation that particles accumulate on the filter screen and cause the filter screen to be blocked. At the same time, by setting the cooperation of the water collecting cover and the tube filter, the device can collect, filter and reuse the spray water, thus effectively avoiding the waste of water resources. The addition of multiple groups of tube filters effectively avoids the blockage of the atomizing nozzles caused by internal particles after the spray water is reused, greatly improving the practicability of the device.
