Description

Technical Field

[0001] The present application relates to the technical field of cooling mist recovery and treatment devices, and in particular to a zinc alloy surface pneumatic cooling mist recovery and treatment device. Background Art

[0002] Zinc alloy is an alloy composed of zinc and other elements. It has good fluidity, is easy to weld, and is corrosion-resistant in the atmosphere. When processing zinc alloy, the prepared zinc alloy liquid needs to be added to the molding tank, and then the zinc alloy liquid in the molding tank is cooled. The cooling method usually adopts atomization cooling. However, during atomization cooling, it is necessary to absorb the excess cooling mist to reduce the surface scarring of the zinc alloy ingot during casting and improve the surface quality of the zinc alloy ingot.

[0003] The existing mist recovery device uses a negative pressure mechanism to suck excess mist into a recovery hood. There are still some problems in the recovery process. The recovered mist adheres to the inner wall of the recovery hood. A small amount of mist liquid is easy to dry if not handled in time. When there is too much mist liquid on the inner wall of the recovery hood, the liquid is easy to drip everywhere and is not easy to collect. Therefore, the present application proposes a zinc alloy surface pneumatic cooling mist recovery and treatment device. Utility Model Content

[0004] The purpose of this application is to address the technical problems pointed out in the background technology and to propose a zinc alloy surface pneumatic cooling mist recovery and treatment device.

[0006] The inner wall of the bottom end of the liquid collecting cover is provided with a guide groove which cooperates with the liquid scraping member to drain liquid.

[0007] Preferably, the negative pressure suction mechanism includes a rotating rod and a negative pressure fan blade installed at the end of the rotating rod, the scraping drive mechanism includes a driving gear fixedly mounted on the side wall of the rotating rod, one side of the driving gear is meshed with a driven gear, the interior of the liquid collecting cover is provided with a rotating ring located on the outside of the driving gear, and the inner wall of the rotating ring is fixedly connected to a gear ring meshed with the driven gear.

[0008] Preferably, one end of the rotating ring is fixedly connected to a pair of transmission support rods, an inner wall of one side of the liquid collecting cover is provided with an annular groove, two transmission support rods are slidably connected in the annular groove, and the inner ring of the driven gear is fixedly inserted with a rotating shaft rotatably connected to the inner wall of one side of the liquid collecting cover.

[0009] Preferably, the liquid scraping member comprises a connecting rod fixedly connected to the side wall of the rotating ring, and a scraper is fixedly connected to one end of the connecting rod close to the liquid collecting cover.

[0010] Preferably, both ends of the scraper extend to both end edges of the liquid collecting cover, and the scraper contacts the inner wall of the liquid collecting cover.

[0011] Preferably, recesses are provided at the junctions between the two sides of the guide groove and the inner wall of the liquid collecting hood to reduce the resistance of the scraper when it moves.

[0012] Preferably, a drain box is provided below the outer end of the liquid collecting cover, a drain pipe is provided at the bottom end of the drain box, the drain box is located directly below the output end of the guide groove, and the guide groove is inclined toward the drain box.

[0013] Compared with the prior art, this application has the following beneficial technical effects:

[0014] The present application arranges a scraping drive mechanism and a scraping member inside the liquid collecting hood, and drives the scraping member to work through the scraping drive mechanism, so that the scraper moves in a circle on the inner wall of the liquid collecting hood. Because the scraper contacts the inner wall of the liquid collecting hood, the mist liquid on the inner wall of the liquid collecting hood can be scraped off in time and discharged outward, thereby preventing the mist liquid from adhering to the inner wall of the liquid collecting hood and drying or randomly dripping, which has a low collection rate.

[0015] By opening an inclined guide groove on the inner wall of the bottom end of the liquid collecting cover, the mist liquid can be collected in the guide groove and discharged quickly under the action of the liquid scraping member. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-4As shown, the present application proposes a zinc alloy surface pneumatic cooling mist recovery and treatment device, including a mist collecting hood 3 arranged on the upper end of a cooling hood 2, the upper end of the cooling hood 2 is open, the outer wall of the cooling hood 2 is fixedly connected with a circular support plate 13, the mist collecting hood 3 is fixedly installed on the upper end of the circular support plate 13, the cooling hood 2 is installed on the upper end of a conveying frame 1, and the interior of the conveying frame 1 conveys the zinc alloy forming groove through a conveying mechanism, and the forming groove is filled with zinc alloy liquid. The interior of the cooling hood 2 is provided with an atomizing cooling mechanism (the atomizing cooling mechanism includes an air source pipe and a liquid pipe, the coolant enters through the liquid pipe, and with the cooperation of the air source pipe, the cooling is completed by spraying, which is a prior art here and will not be described in detail). A liquid collecting hood 4 is installed on one side of the mist collecting hood 3. The liquid collecting hood 4 can be set as a pair or as a plurality. A negative pressure suction mechanism is set inside the liquid collecting hood 4, and a scraper 9 is also installed inside the liquid collecting hood 4. A scraper driving mechanism 8 is installed between the scraper 9 and the negative pressure suction mechanism. When the negative pressure suction mechanism is working, the scraper driving mechanism 8 drives the scraper 9 to move in a circular motion inside the liquid collecting hood 4.

[0031] Furthermore, the inner wall of the bottom end of the liquid collecting cover 4 is provided with a guide groove 10 for draining liquid in cooperation with the scraper 9, and the guide groove 10 is arc-shaped. A drain box 5 is provided below the outer end of the liquid collecting cover 4, a support plate is connected between the drain box 5 and the cooling cover 2, a drain pipe is provided at the bottom end of the drain box 5, the drain pipe is connected to the external collection box (existing technology, not shown in the figure), a valve is provided on the drain pipe, the drain box 5 is located directly below the output end of the guide groove 10, and the guide groove 10 is inclined toward the drain box 5, so that the mist liquid accumulated inside can be smoothly discharged to the outside.

[0032] Specifically, the negative pressure suction mechanism includes a rotating rod 7 and a negative pressure fan blade 12 installed at the end of the rotating rod 7. A servo motor 6 is installed on the outer side of one end of the liquid collecting cover 4. The output shaft of the servo motor 6 is fixedly connected to the rotating rod 7. The scraping drive mechanism 8 includes a driving gear 803 fixedly sleeved on the side wall of the rotating rod 7. One side of the driving gear 803 is meshed with a driven gear 804. The inner ring of the driven gear 804 is fixedly plugged with a rotating shaft rotatably connected to the inner wall of one side of the liquid collecting cover 4, which supports the driven gear 804. A rotating ring 801 is provided inside the outer side of the driving gear 803, and a gear ring 802 meshing with the driven gear 804 is fixedly connected to the inner wall of the rotating ring 801. The driven gear 804 can drive the gear ring 802 to rotate one circle only after several circles of rotation. A pair of transmission support rods 805 are fixedly connected to one end of the rotating ring 801, and an annular groove is provided on the inner wall of one side of the liquid collecting cover 4. The two transmission support rods 805 are both slidably connected in the annular groove, which can stably support the rotating ring 801 and make the rotating ring 801 move in a circle around the rotating rod 7.

[0033] Furthermore, the scraper 9 includes a connecting rod 902 fixedly connected to the side wall of the rotating ring 801, and the end of the connecting rod 902 close to the liquid collecting hood 4 is fixedly connected to a scraper 901, and the negative pressure fan blade 12 is located on the inner side of the scraper 901; the two ends of the scraper 901 extend to the two end edges of the liquid collecting hood 4, and the scraper 901 contacts the inner wall of the liquid collecting hood 4; a recess 11 is provided at the junction of the two sides of the guide groove 10 and the inner wall of the liquid collecting hood 4 to reduce the resistance of the scraper 901 during movement, so that the mist liquid attached to the inner wall of the liquid collecting hood 4 can be smoothly scraped into the guide groove 10 by the scraper 901, and the scraper 901 will not be hindered when passing through the guide groove 10.

[0034] The specific working principle is: after the atomizing cooling mechanism inside the cooling hood 2 cools the liquid in the zinc alloy forming tank, the servo motor 6 is started, and the negative pressure fan blades 12 are driven to work through the rotating rod 7, so that the excess liquid inside the cooling hood 2 is sucked into the two liquid collecting hoods 4, and the sucked mist liquid will adhere to the inner wall of the liquid collecting hood 4. By arranging a scraping drive mechanism 8 and a scraping component 9 inside the liquid collecting hood 4, the scraping drive mechanism 8 drives the scraping component 9 to work, so that the mist liquid on the inner wall of the liquid collecting hood 4 is scraped off in time and discharged outward. Specifically, the rotation of the rotating rod 7 drives the driving gear 803 to rotate, the driving gear 803 meshes with the driven gear 804, the driven gear 804 meshes with the gear ring 802 for transmission, and finally drives the rotating ring 801 to rotate. The rotating ring 801 rotates through the connecting rod 902 to drive the scraper 901 to move in a circular motion inside the liquid collecting cover 4. It is worth noting that because the gear 804 rotates several times to drive the gear ring 802 to rotate one circle, the circular motion speed of the scraper 901 is many times lower than the speed of the rotating rod 7, and unnecessary wear will not be caused to the inner wall of the liquid collecting cover 4 due to the high speed. A guide groove 10 is provided at the bottom of the inner wall of the liquid collecting cover 4. When the scraper 901 moves in a circular motion, it will scrape off the liquid attached to the inner wall of the liquid collecting cover 4, and make the liquid flow into the guide groove 10 in a concentrated manner, and finally discharge it into the drain box 5. The collected coolant can be discharged by opening the valve on the drain pipe at the bottom of the drain box 5.
