DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 6 As shown, an air purification device for a starch processing workshop of the present invention comprises a purification cylinder 1 and a vertical pipe 2, wherein the purification cylinder 1 is vertical, and the interior of the purification cylinder 1 is used to provide space for air purification work, the vertical pipe 2 is vertically located at the axial position of the purification cylinder 1, and multiple groups of nozzle structures 3 are arranged on the outer wall of the vertical pipe 2, and the nozzle structure 3 is used to spray water mist into the purification cylinder 1, and a water curtain unit 4 is arranged on the top of the vertical pipe 2, and the water curtain unit 4 is used to spray a water curtain into the purification cylinder 1, and the water curtain extends to the inner wall of the purification cylinder 1, and an air inlet pipe 5 is connected and arranged on the outer wall of the purification cylinder 1, and the air inlet pipe 5 discharges dust-containing gas into the purification cylinder 1 along the tangential direction of the inner wall of the purification cylinder 1.

[0020] In detail, the purification cylinder 1 is vertical, the bottom of the purification cylinder 1 is sealed, the top of the purification cylinder 1 is open, and the opening is used to discharge the purified air, the vertical pipe 2 is vertically located at the axial position of the purification cylinder 1, and the vertical pipe 2 is used to provide support for multiple groups of nozzle structures 3 and the water curtain unit 4, the multiple groups of nozzle structures 3 and the water curtain unit 4 are connected to the vertical pipe 2, water can be supplied into the nozzle structure 3 and the water curtain unit 4 through the vertical pipe 2, and the air inlet pipe 5 is installed on the lower side of the outer wall of the purification cylinder 1. Since the air inlet pipe 5 discharges the dust-containing gas into the purification cylinder 1 along the tangential direction of the inner wall of the purification cylinder 1, the gas can rotate and flow in the purification cylinder 1, and the gas filled in the purification cylinder 1 flows toward the opening position at the top of the purification cylinder 1, so the gas spirally flows in the purification cylinder 1, and the particulate impurities in the gas are gathered near the inner wall of the purification cylinder 1 under the action of centrifugal force, thereby realizing the preliminary separation of impurities. When the dust-containing gas rises to the multiple groups of nozzles When structure 3 is in the position, the water mist sprayed by the multiple groups of nozzle structures 3 can adsorb impurities in the air. At this time, the water mist performs secondary purification on the air. The water mist absorbs impurities and moves toward the inner wall of the purification tube 1. The water mist and impurities are adsorbed on the inner wall of the purification tube 1. The water mist simultaneously adsorbs the impurities centrifugally separated on the inner wall of the purification tube 1, thereby preventing impurities from rising with the airflow near the inner wall of the purification tube 1, thereby achieving the capture and interception of impurities. When the air rises to the position of the water curtain unit 4, the water curtain formed on the water curtain unit 4 adsorbs and separates the impurities in the gas again, thereby achieving multi-stage purification of the air, and the water that falls on the inner wall of the purification tube 1 can flow downward along the inner wall of the purification tube 1. At this time, the water flow will flush the impurities adsorbed on the inner wall of the purification tube 1, thereby causing the impurities to gather at the bottom of the purification tube 1, thereby achieving multi-stage and interrelated purification of impurities in the air.

[0021] By utilizing the swirling motion of air and the combined use of water mist and water curtain, multi-stage purification of air is achieved, ensuring the thoroughness and high efficiency of purification; through the secondary purification of the air after swirling by water mist, the adsorption and capture of impurities separated by water mist to the inner wall of the purification tube 1 after the air swirling, the tertiary purification of the air by the water curtain and the flushing of the impurities captured by the water mist by the water flow formed by the water curtain on the inner wall of the purification tube 1, an interrelated and multi-purification mode of the air is achieved; this air purification mode can purify the air in large quantities, continuously and quickly; in summary, the air purification equipment not only effectively solves the dust pollution problem in the starch sugar processing process, but also provides an efficient and environmentally friendly solution for the field of industrial air purification through its unique multi-stage purification design, self-cleaning ability and resource-saving characteristics.

[0022] Furthermore, the purification cylinder 1 is in a cone shape that is wide at the top and narrow at the bottom, and an inner buckle area 6 facing the inner side of the purification cylinder 1 is provided at the top of the purification cylinder 1 .

[0023] In detail, by making the shape of the purification tube 1 a cone that is wide at the top and narrow at the bottom, the water sprayed onto the inner wall of the purification tube 1 by the water curtain can flow downward smoothly, avoiding the situation that when the purification tube 1 is in the shape of a cone that is narrow at the top and wide at the bottom, the water on the inner wall of the purification tube 1 will directly drip and cannot flow along the inner wall of the purification tube 1. At the same time, it avoids the phenomenon that the water flows too fast when the purification tube 1 is in the shape of a straight cylinder.

[0024] By providing the inner buckle area 6 at the top of the purification cartridge 1, the water mist that follows the air in a swirling motion can be conveniently intercepted and captured, thereby reducing the loss of water resources.

[0025] Furthermore, the water curtain unit 4 is composed of a first water diversion bucket 7 and a second water diversion bucket 8 distributed up and down, the first water diversion bucket 7 is located outside the second water diversion bucket 8, the cross section of the first water diversion bucket 7 and the cross section of the second water diversion bucket 8 are both arc-shaped, and the space between the first water diversion bucket 7 and the second water diversion bucket 8 is used to diffuse the water flow outward and form the water flow into a water curtain shape; The first water diversion bucket 7 and the second water diversion bucket 8 are both fixed on the top of the vertical pipe 2. A plurality of water holes 9 are opened on the top of the vertical pipe 2. The space between the first water diversion bucket 7 and the second water diversion bucket 8 is connected to the water holes 9.

[0026] In detail, the water in the vertical pipe 2 flows upward and enters the space between the first water diverter bucket 7 and the second water diverter bucket 8 through multiple water holes 9. Due to the shape restrictions of the first water diverter bucket 7 and the second water diverter bucket 8, the water in the space can be sprayed all around, and the thickness of the sprayed water is small, thereby forming a water curtain shielding area between the water curtain unit 4 and the inner wall of the purification cylinder 1, which is convenient for using the water curtain to filter the air.

[0027] Furthermore, the nozzle structure 3 includes a capillary tube 10 connected and installed on the vertical pipe 2, the length direction of the capillary tube 10 is along the radial direction of the vertical pipe 2, two side openings 11 are relatively opened on the capillary tube 10, an impact body 12 is arranged in the capillary tube 10, and the end of the impact body 12 facing the vertical pipe 2 is arranged in an arc shape.

[0028] In detail, the water in the vertical pipe 2 enters the capillary 10 and impacts the arc surface at the end of the impact body 12, so that the water is quickly dispersed through the side port 11 by utilizing the arc surface and the impact effect, and the water is conveniently diffused into the purification cylinder 1 in the form of water mist.

[0029] Furthermore, the impact body 12 slides in the capillary 10 , and the impact body 12 and the capillary 10 are connected via a first elastic piece 13 .

[0030] In detail, when water enters the side port 11, the water generates a driving force on the impact body 12, thereby causing the impact body 12 to slide in the capillary 10, and the first spring piece 13 undergoes elastic deformation. When the first spring piece 13 is deformed to the maximum, the first spring piece 13 pushes the impact body 12 in the reverse direction to cause the impact body 12 to actively impact the water in the capillary 10 in the reverse direction, thereby improving the impact effect. When the deformation of the first spring piece 13 decreases, the water pressure generates a force on the impact body 12 again, thereby causing the impact body 12 to reciprocate in the capillary 10, causing the impact body 12 to repeatedly impact the water in the capillary 10, thereby reducing the size of water mist particles and improving the atomization effect.

[0031] In actual use, the impact body 12 in the natural state of the first spring sheet 13 can block the side opening 11. When the water pressure pushes the impact body 12 to move, the impact body 12 deviates from the side opening 11, and the side opening 11 is in an open state.

[0032] Furthermore, the vertical pipe 2 rotates in the purification cylinder 1 , and a plurality of auxiliary blades 14 are provided on the outer wall of the vertical pipe 2 .

[0033] In detail, the auxiliary fan blades 14 are close to the air inlet pipe 5 in the vertical direction. When the vertical pipe 2 rotates, it can drive multiple groups of nozzle structures 3 and multiple auxiliary fan blades 14 to rotate. The nozzle structure 3 performs a rotary spray motion. The auxiliary fan blades 14 can provide auxiliary thrust for the air entering the purification cylinder 1 and swirling, thereby increasing the air swirling motion speed.

[0034] Furthermore, the bottom of the vertical pipe 2 extends to the bottom of the purification cylinder 1, and a bracket 15 is fixed to the bottom of the purification cylinder 1. The bottom of the vertical pipe 2 is rotatably installed on the bracket 15, and the bracket 15 blocks the bottom of the vertical pipe 2. A reflux pipe 16 and a motor 17 are provided on the bracket 15. The reflux pipe 16 passes through the bracket 15 and is connected to the vertical pipe 2. A transmission wheel 18 is provided at the output end of the motor 17, and the transmission wheel 18 is transmission-connected to the outer wall of the vertical pipe 2.

[0035] In detail, the bracket 15 can provide support for the vertical pipe 2, the return pipe 16, the motor 17 and the transmission wheel 18, so that the return pipe 16 in a static state can supply water to the dynamic vertical pipe 2, and the motor 17 and the transmission wheel 18 can provide power for the rotational movement of the vertical pipe 2.

[0036] Furthermore, the bottom of the purification cartridge 1 is connected to a collecting box 19, and a water pump 20 is provided at the bottom of the collecting box 19. The input end of the water pump 20 is connected to the collecting box 19, and the output end of the water pump 20 is connected to the reflux pipe 16. A filter plate 21 is inclined inside the collecting box 19, and a sewage collecting trough plate 22 is provided on the outer wall of the collecting box 19. The sewage collecting trough plate 22 is connected to the collecting box 19. A slide plate 23 is provided at the bottom of the sewage collecting trough plate 22. The top of the slide plate 23 is inclined and slidably inserted into the sewage collecting trough plate 22. The slide plate 23 and the collecting box 19 are connected by a second elastic piece 24.

[0037] In detail, the water in the purification cartridge 1 can enter the collection box 19, the filter plate 21 filters the water in the collection box 19, and the filtered water is supplied to the vertical pipe 2 through the water pump 20 and the reflux pipe 16, thereby realizing the recycling of water.

[0038] Since the filter plate 21 is inclined, the water in the collection box 19 can flush the impurities connected to the filter plate 21, so that the impurities enter the slide plate 23 in the sewage collecting trough plate 22 and gather. The second spring piece 24 provides elastic thrust for the slide plate 23. When a large number of impurities gather on the slide plate 23, the slide plate 23 is pulled down and the top of the slide plate 23 is exposed, thereby facilitating the cleaning of the impurities gathered on the top of the slide plate 23 out of the collection box 19. The slide plate 23 can be slidably installed on the outer wall of the collection box 19.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
