Description

Technical Field

[0001] The present invention relates to the field of dust treatment equipment, and in particular to a dust treatment spray tower and a use method thereof. Background Art

[0002] Shot blasting of nonferrous metals is a mechanical surface treatment process that cleans and strengthens metal surfaces to enhance their performance and appearance. The basic principle of shot blasting is to use a high-speed rotating impeller to hurl projectiles (including cast steel shot, cut wire shot, stainless steel shot, and other types) at the workpiece surface, thereby cleaning and strengthening the workpiece. This technology removes scale, dirt, and other impurities from the workpiece surface, while also improving the surface roughness to enhance the adhesion and durability of subsequent coatings. Shot blasting has the advantages of high efficiency, high degree of automation and wide range of applications. However, shot blasting will generate a large amount of dust-laden gas, in which the dust includes material oxides, dirt and other substances. Especially in the aluminum processing industry, because aluminum powder is flammable and explosive, the dust-laden gas needs to be separated and treated. During the treatment process, the dust-laden gas needs to be passed into the spray tower for adsorption by water spraying. However, after the dust-laden gas is passed into the current spray tower, it can only rely on the passive contact between the sprayed water and the dust in the air to adsorb and remove the dust. After the water is sprayed, it drips to the bottom of the spray tower to realize the dust removal action, and the residence time of the water in the air cannot be extended. There is a problem of high water consumption. In addition, since the coverage range of the water sprayed by the nozzle is fixed and the water spray range is limited, the dust separation is not thorough enough and the treatment effect is poor.

[0011] Preferably, a wheel frame is fixed on the top side of the positioning block, and the wheel frame is a U-shaped structure with an opening toward the positioning plate. A positioning wheel is rotatably arranged inside the wheel frame and extends into the wheel groove on the outer edge of the positioning plate. The storage rack is a rectangular frame, and a connecting block rotatably engaged with the support seat is fixed on the top of the storage rack.

[0013] The method for using the dust treatment spray tower comprises the following steps: a. During use, the dust-laden air to be sprayed and adsorbed is fed into the spray tower through the feed pipe of the spray tower. At the same time, the spray water is connected to the liquid inlet of the outer sleeve, and the spray water is transported to the cavity between the outer sleeve and the transmission rod through the liquid inlet. The bottom of the outer sleeve is sealed by the positioning plate. The transmission rod is driven by a motor to support multiple groups of transfer shells and the retaining rack, bracket, storage rack, and absorption layer below to rotate synchronously. The positioning assembly remains stationary under the support of the outer sleeve. At this time, the bracket and the storage rack supporting the absorption layer are used as a gas stirring structure to stir and mix the dust-laden gas fed into the spray tower along the feed pipe; b. The spray water input into the outer sleeve is gathered between the inner and outer rings of the positioning plate. The fixed hole of the inner ring serves as the discharge channel for the spray water. When the multiple sets of intermediate shells rotate around the inner ring following the transmission rod, when the intermediate shells rotate to a position close to the feed pipe, the movable hole of the intermediate shells in this group is connected to the fixed hole of the inner ring. The spray water in the outer sleeve enters the movable hole along the fixed hole, and is sent into the bracket along the intermediate shell and the supply pipe. It is sprayed out through the spray hole on the outside of the bracket. At this time, the bracket group is located close to the feed pipe, ensuring that the multiple sets of brackets can automatically spray water when they rotate to the feed pipe position, and automatically stop the water spraying action when the feed pipe position is staggered; c. When the bracket rotates to the side close to the feed pipe, the positioning wheel on the top side of the bracket is pushed outward by the large-diameter outward expansion section, so that the positioning wheel drives the lower positioning block to slide outward along the restraining groove of the retaining frame, and then the support arm on the bottom side of the positioning block pulls the bracket outward to pull it to a horizontal state. The bracket cooperates with the storage rack in a drooping state under the action of its own weight to pull the absorption layer serving as the stirring fan structure to an expanded state, so that the absorption layer is used as a guide surface for spraying liquid downward along the bracket, and the absorption layer prolongs the dripping time of the spray liquid, and the absorption layer serves as an attachment surface for the spray liquid to adhere to and absorb dust; d. When the bracket rotates to the transition section and the inward section, the outward tightening effect of the outward expansion section on the positioning wheel is released, and the bracket rotates downward under the action of its own weight. At the same time, the elastic part pulls the positioning block to retract toward the inward section, thereby assisting in retracting the bracket downward. At this time, the absorption layer rotates downward, and the coil spring on the inside of the storage groove supports the rotation of the reel. The reel reels the absorption layer, and then stores the absorption layer into the storage groove. At the same time, the scrapers on both sides of the storage rack are used to gather and scrape off the dust-containing water on both sides of the absorption layer. Therefore, when the bracket rotates to a direction away from the feed pipe, the bracket is retracted to collect the dust-containing water attached to the absorption layer and discharge it downward, completing the dust-containing gas spray adsorption process.

[0014] The beneficial effects are as follows: 1. The present invention provides an outer sleeve and a rotatable transmission rod inside the spray tower, and uses the cavity between the outer sleeve and the transmission rod as a spray water delivery channel, and provides an inner ring on the top side of the positioning plate at the bottom end of the outer sleeve, and the fixed hole of the inner ring close to the feed pipe position serves as a spray water output channel. In the process of multiple groups of transfer shells following the rotation of the transmission rod, the multiple groups of transfer shells are rotated to the feed pipe position in turn, so that the multiple groups of transfer shells are connected with the inner ring in turn, thereby ensuring that the multiple groups of brackets automatically open the spray drainage channel when they rotate to the feed pipe position, and automatically close the spray drainage channel after staggering the feed pipe position, and then use the spray hole of the bracket to spray a water curtain outward along the length direction of the bracket, so as to correspondingly adsorb the dust-laden gas input into the spray tower from the feed pipe; 2. The absorption layer is supported upward by the bracket, and the bracket is used in conjunction with the absorption layer with leakage holes to support and guide the water liquid that absorbs the dust-laden gas. The water liquid flows downward along the absorption layer to increase the residence time of the water liquid near the feed pipe and improve the dust adsorption effect; 3. When the bracket rotates to the side away from the feed pipe, the movable hole and the fixed hole are staggered, and the water spraying action of the spray holes on this group of brackets is automatically closed, saving water and reducing the water consumption in the dust-laden gas spray adsorption process, which is more environmentally friendly. 4. In addition, a positioning plate is provided as a guide support structure for the positioning wheel on the top side of the bracket. When the bracket rotates to a position close to the feed pipe, the positioning wheel is supported by the outward expansion section to drive the positioning block to slide outward, thereby pulling the support arm to pull the bracket upward, thereby automatically unfolding the absorption layer near the feed pipe, thereby improving the absorption and filtering effect of the absorption layer on dust during its rotation around the outer sleeve; 5. When the bracket rotates to the side away from the feed pipe, the spray hole is closed and the transition section and the retracted section gradually support the positioning wheel to slide inward. At the same time, under the action of the bracket's own weight and the pulling action of the elastic part, the outer end of the bracket is rotated downward to a vertical state, so that the absorption layer can be rolled up and stored by using the coil spring and the reel. At the same time, the water on both sides of the absorption layer is scraped off by the scraper, so that the absorption layer and the bracket are folded up and rotated to a drooping state, so that the absorbed and collected water can be discharged and separated downward on the side away from the feed pipe, and the area of the absorption layer can be reduced, thereby reducing the overall rotation resistance of the connecting part below the transmission rod and reducing the equipment load.

The outer circumferences of the multiple groups of transfer shells 7 are all provided with movable holes 701 corresponding to the fixing holes 402a. When the disc body composed of the multiple groups of transfer shells 7 rotates under the support of the transmission rod 5, when the transfer shell 7 rotates to the position of the fixing hole 402a, the movable hole 701 of the transfer shell 7 is connected with the fixed hole 402a of the inner ring 402. At this time, the spray water inside the outer sleeve 3 can enter the corresponding transfer shell 7 along the fixed hole 402a and the movable hole 701 in sequence.

[0020] As an optional embodiment, a liquid discharge pipe 102 is vertically passed through the bottom of the spray tower 1. The spray water that absorbs dust is output along the liquid discharge pipe 102 to the auger filter press, and the dust is filtered out to achieve solid-liquid separation, completing the dust removal process.

A rotating frame 201 supporting the outer sleeve 3 is fixed on the top side of the top cover 2. The top of the outer sleeve 3 is fixedly connected to the rotating frame 201 through a flange. A liquid inlet 302 is longitudinally penetrated on the front side of the outer sleeve 3 on the inner side of the rotating frame 201. The motor 11 is fixed to the top side of the rotating frame 201 by bolts. A gas exhaust pipe 202 is provided on one side of the top cover 2. The gas screened out by the dust absorbed by the water is discharged outward along the gas exhaust pipe 202; A rotating seat 601 is provided around the bottom of the holder 6 to support the rotation of the bracket 8. A support seat 602 is fixed to the bottom of the holder 6 inside the rotating seat 601. Vertically extending storage racks 9 are provided below the multiple groups of support racks 602 corresponding to the bracket 8. An absorption layer 10 with a filter structure is connected between the storage racks 9 and the bracket 8. The top side of the retainer 6 is provided with a plurality of groups of vertically penetrating constraint grooves 604 corresponding to the bracket 8. The constraint grooves 604 extend radially along the outer sleeve 3. Side shafts 802 are fixed on both sides of the middle section of the bracket 8. An upwardly extending support arm 803 is hinged on the outer side of the side shaft 802. A positioning block 804 is provided above the support arm 803, which slides in the constraint groove 604. A support ear 804a for the hinged support arm 803 is fixed to the bottom side of the positioning block 804. The inner end of the bracket 8 is fixed with swing ears 805 arranged on both sides of the supply pipe 702. The bracket 8 is hinged to the rotating seat 601 on the bottom side of the retaining frame 6 through the swing ears 805, so that the bracket 8 can be rotated outward and deployed and folded inward on the bottom side of the retaining frame 6. A pull ring 605 is fixed to the inner side of the constraint groove 604 near the axis of the retaining frame 6. An elastic part 808 connected to the pull ring 605 is fixed to the outer side of the positioning block 804. The elastic part 808 can be a tension spring or an elastic rope, preferably a tension spring, to increase the service life of the equipment. The positioning plate 401 extends toward the side of the feed pipe 101 to form an arc-shaped outward expansion section 401a, and the positioning plate 401 extends inward away from the feed pipe 101 to form an arc-shaped inward retracted section 401c. The radius of the outward expansion section 401a is greater than the radius of the inward retracted section 401c. The rounded transition between the inward retracted section 401c and the outward expansion section 401a forms a transition section 401b. The outer side of the positioning plate 401 extends along its outer edge to form an inwardly concave wheel groove. The top side of the positioning block 804 is fixed with a wheel frame 806, which is a U-shaped structure with an opening toward the positioning plate 401. The wheel frame 806 is internally provided with a positioning wheel 807 that extends into the wheel groove along the outer edge of the positioning plate 401. The elastic portion 808 is used to tighten the positioning block 804, and the deadweight of the bracket 8 is used to keep the bracket 8 in the state of tightening the support arm 803 downward. The support arm 803 is used to pull the positioning block 804 so that the top side positioning wheel 807 is pressed against the wheel groove of the positioning plate 401 to hold the bracket 8 in place. During the overall rotation of the brackets 6 and the multiple groups of brackets 8, the positioning wheel 807 is rotated to different positions outside the positioning plate 401 to change the angular position of the bracket 8, thereby changing the unfolding and folding state of the absorbent layer 10. The storage rack 9 is a rectangular frame. A connecting block 901 that rotates to match the support seat 602 is fixed on the top of the storage rack 9. A vertically extending storage groove 902 is passed through the middle of the storage rack 9. The bottom edge of the absorbent layer 10 extends into the storage groove 902. The storage rack 9 remains in a drooping state under the action of its own weight. The absorption layer 10 is made of a cloth material densely covered with leak holes 10a, which facilitates the filtration of gas through the absorption layer 10 to absorb water and dust, thereby increasing the residence time of water at the feed pipe 101. Support rings 904 are fixed on the upper and lower sides of the storage groove 902. A reel 905 for winding up the absorption layer 10 is rotatably provided in the middle of the support ring 904. The bottom edge of the absorption layer 10 is bonded and fixed to the outer circumference of the reel 905. The two ends of the bottom edge of the absorption layer 10 are wound and stored by two sets of reels 905 on the upper and lower sides of the storage groove 902, and a support reel 905 is provided on the inner side of the support ring 904 to wind up the storage absorption layer 10. The two sets of reels 906 on the upper and lower sides can fan the fan. The upper and lower sides of the shaped absorption layer 10 are completely rolled up, thereby ensuring that the two sides of the absorption layer 10 of different lengths can be correspondingly wound and retracted by two reels 905, ensuring that the absorption layer 10 can be stored in the storage groove 902 as a whole, and scrapers 12 are fixed on both sides of the storage rack 9. The two groups of scrapers 12 are symmetrically arranged on both sides of the absorption layer 10, and the outer edge of the scraper 12 is fixed with a scraping strip 12a that abuts against the outer surface of the absorption layer 10. The scraping strip 12a is made of rubber, which is convenient for using the scraping strip 12a to scrape off the water adhered to the outside of the absorption layer 10 that is folded down, so as to facilitate the water that absorbs dust to be gathered and discharged downward. The outside of the storage rack 9 is penetrated by a side hole 903 for fixing the scraper 12 with screws.

[0021] The method of using the dust treatment spray tower includes the following steps: a. During use, the dust-laden air to be sprayed and adsorbed is fed into the spray tower 1 along the feed pipe 101 of the spray tower 1. At the same time, the spray water is connected to the liquid inlet 302 of the outer sleeve 3. The spray water is delivered to the cavity between the outer sleeve 3 and the transmission rod 5 through the liquid inlet 302. The bottom opening of the outer sleeve 3 is sealed by the positioning plate 401. The transmission rod 5 is driven by the motor 11 to support the multiple groups of transfer shells 7 and the retaining frame 6, bracket 8, storage rack 9, and absorption layer 10 below to rotate synchronously. The positioning assembly 4 remains stationary under the support of the outer sleeve 3. At this time, the bracket 8 and the storage rack 9 supporting the absorption layer 10 are used as a gas stirring structure to stir and mix the dust-laden gas fed into the spray tower 1 along the feed pipe 101; b. The spray water input into the outer sleeve 3 is gathered between the inner ring 402 and the outer ring 403 of the positioning plate 401. The fixed hole 402a of the inner ring 402 serves as a spray water discharge channel. When the multiple groups of intermediate shells 7 rotate around the inner ring 402 following the transmission rod 5, when the intermediate shells 7 rotate to a position close to the feed pipe 101, the movable hole 701 of the intermediate shells 7 is connected with the fixed hole 402a of the inner ring 402. The spray water in the outer sleeve 3 enters the movable hole 701 along the fixed hole 402a, and is sent into the bracket 8 along the intermediate shell 7 and the supply pipe 702, and is sprayed out through the spray hole 801 on the outside of the bracket 8. At this time, the bracket 8 is located close to the feed pipe 101 to ensure that the multiple groups of brackets 8 can automatically spray water when they rotate to the position of the feed pipe 101, and automatically stop the water spraying action when they are staggered from the position of the feed pipe 101; c. When the bracket 8 rotates to the side close to the feed pipe 101, the positioning wheel 807 on the top side of the bracket 8 is pushed outward by the large-diameter outward expansion section 401a, so that the positioning wheel 807 drives the lower positioning block 804 to slide outward along the constraint groove 604 of the retaining frame 6, and then the support arm 803 on the bottom side of the positioning block 804 is used to pull the bracket 8 outward to pull the bracket 8 to a horizontal state. The bracket 8 is used to cooperate with the storage rack 9 in a drooping state under the action of its own weight to pull the absorption layer 10 as a stirring fan structure to an expanded state, so that the absorption layer 10 is used as a guide surface for spraying liquid downward along the bracket 8, and the absorption layer 10 is used to extend the time for the spray liquid to drip downward, and the absorption layer 10 is used as an attachment surface for the spray liquid to adhere to and absorb dust; d. When the bracket 8 rotates to the transition section 401b and the inward section 401c, the outward tightening effect of the outward expansion section 401a on the positioning wheel 807 is released, and the bracket 8 rotates downward under the action of its own weight. At the same time, the elastic portion 808 pulls the positioning block 804 to retract toward the inward section 401c, thereby assisting in retracting the bracket 8 downward. At this time, the absorption layer 10 rotates downward, and the coil spring 906 inside the storage groove 902 supports the rotation of the reel 905. The reel 905 reels the absorption layer 10, and then stores the absorption layer 10 into the storage groove 902. At the same time, the scrapers 12 on both sides of the storage rack 9 are used to gather and scrape off the dust-containing water liquid on both sides of the absorption layer 10, so that the bracket 8 is retracted when it rotates away from the feed pipe 101 to collect the dust-containing water liquid attached to the absorption layer 10 and discharge it downward, completing the dust-containing gas spray adsorption process; An outer sleeve 3 and a rotatable transmission rod 5 are provided inside the spray tower 1, and the cavity between the outer sleeve 3 and the transmission rod 5 is used as a spray water delivery channel, and an inner ring 402 is provided on the top side of the positioning plate 401 at the bottom end of the outer sleeve 3, and the fixing hole 402a of the inner ring 402 near the position of the feed pipe 101 serves as a spray water output channel. In the process of the multiple groups of transfer shells 7 rotating following the transmission rod 5, the multiple groups of transfer shells 7 are rotated to the position of the feed pipe 101 in turn, so as to connect the multiple groups of transfer shells 7 with the inner ring 402 in turn, thereby ensuring that the multiple groups of brackets 8 automatically open the spray drainage channel when they rotate to the position of the feed pipe 101, and automatically close the spray drainage channel after staggering the position of the feed pipe 101, and then use the spray hole 801 of the bracket 8 to spray a water curtain outward along the length direction of the bracket 8, thereby correspondingly adsorbing the dust-laden gas input into the spray tower 1 from the feed pipe 101; The absorbing layer 10 is supported upward by the bracket 8, and the bracket 8 cooperates with the absorbing layer 10 with the leakage hole 10a to support and guide the water liquid that absorbs the dust-laden gas. The water liquid flows downward along the absorbing layer 10 to increase the residence time of the water liquid near the feed pipe 101, thereby improving the dust adsorption effect. When the bracket 8 rotates to the side away from the feed pipe 101, the movable hole 701 and the fixed hole 402a are staggered, and the water spraying action of the spray holes 801 on the bracket 8 is automatically closed, thereby saving water and reducing the water consumption in the dust-laden gas spray adsorption process, which is more environmentally friendly. In addition, a positioning plate 401 is provided as a guide and support structure for the positioning wheel 807 on the top side of the bracket 8. When the bracket 8 rotates to a position close to the feed pipe 101, the positioning wheel 807 is supported by the outward expansion section 401a to drive the positioning block 804 to slide outward, thereby pulling the support arm 803 to pull the bracket 8 upward, thereby automatically unfolding the absorption layer 10 near the feed pipe 101, thereby improving the absorption and filtering effect of the absorption layer 10 on dust during its rotation around the outer sleeve 3. When the bracket 8 rotates to the side away from the feed pipe 101, the spray hole 801 is closed and the transition section 401b and the retracted section 401c gradually support the positioning wheel 807 to slide inward. At the same time, under the action of the bracket 8's own weight and the pulling action of the elastic part 808, the outer end of the bracket 8 is rotated downward to a vertical state, so that the absorption layer 10 can be rolled up and stored by using the coil spring 906 and the reel 905. At the same time, the water on both sides of the absorption layer 10 is scraped off by the scraper 12, so that the absorption layer 10 and the bracket 8 are folded up and rotated to a drooping state, so that the absorbed and collected water can be discharged and separated downward on the side away from the feed pipe 101, and the area of the absorption layer 10 can be reduced, thereby reducing the overall rotation resistance of the connecting part below the transmission rod 5 and reducing the equipment load.

At this time, the bracket (8) cooperates with the storage rack (9) to support the absorption layer (10) as a gas stirring structure to stir and mix the dust-laden gas fed into the spray tower (1) along the feed pipe (101); b. The spray water input into the outer sleeve (3) is gathered between the inner ring (402) and the outer ring (403) of the positioning plate (401). The fixed hole (402a) of the inner ring (402) serves as a spray water discharge channel. When the plurality of intermediate rotating shells (7) rotate around the inner ring (402) following the transmission rod (5), when the intermediate rotating shell (7) rotates to a position close to the feed pipe (101), the movable hole (701) of the intermediate rotating shell (7) and the fixed hole (402a) of the inner ring (402) are connected.
