Description

TECHNICAL FIELD

[0001] The utility model relates to a fume treatment technical field of roasting ash machine, concretely is a kind of roasting ash machine with manual regulating type cooler. BACKGROUND

[0002] Roasting ash machine is also called aluminum ash roasting machine, which is a professional equipment for processing aluminum ash. According to the different physical properties and specific gravity of solid objects and liquid objects, the metallic aluminum and ash in the aluminum ash are separated. The hot aluminum ash discharged from the furnace contains a certain proportion of metallic aluminum. The aluminum ash is added into the roasting ash machine, which has an adjustable height stirring device. The metallic aluminum mixed by stirring gradually sinks to the bottom of the container to form a molten pool. The ash stays on the upper part of the molten pool. Under the action of stirring, the ash is discharged from the ash outlet on the upper part of the container, and the aluminum liquid is discharged from the discharge hole at the bottom of the container and directly cast into aluminum ingots.

[0003] Since aluminum can burn and oxidize to form smoke pollution during stirring, an exhaust device is provided on the upper part of the container. Under the action of the rear fan, the flue gas enters the water bath dust collector or pulse dust collector after cyclone separation. The clean gas after treatment is discharged into the atmosphere. However, the smoke formed by burning and oxidation has high dust content, large particles and high temperature, which acts on the dust removal equipment for a long time, reducing the service life of the dust removal equipment. Therefore, a structure needs to be designed to reduce the dust content of the extracted flue gas, reduce the load of the dust collector, and the cooler does not affect the normal use of the roasting ash machine.

[0004] Therefore, we propose a roasting ash machine with manual regulating type cooler. UTILITY MODEL CONTENTS

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution:

[0023] Example 1: As Figure 1 As shown, the main body of the manually adjustable cooler for the ash roasting machine is a cooling interception sleeve 2, which is connected to one end of the exhaust pipe 1 through a flange, while the other end of the cooling interception sleeve 2 is connected to a pipe extending to the outer dust removal equipment.

[0024] The entire cooling interception sleeve 2 is fixed with a locking frame 3 on its outer wall. The locking frame 3 is integrated with the cooling interception sleeve 2 and prevents leakage during the flue gas interception process. A sealing plate 10 is installed on the locking frame 3 to seal the gaps when the baffle plate 12 moves. The baffle plate 12 is slidably connected inside the locking frame 3. The main body of the baffle plate 12 is hollow, and perforated plates are provided on both sides. The holes on the perforated plates on both sides are staggered. When the dust-laden flue gas in the exhaust pipe 1 enters the perforated plate side, it is intercepted by the baffle plate 12 and falls to the bottom of the locking frame 3. When the entire ash roasting machine is stopped for maintenance, the baffle plate 12 on the entire locking frame 3 is pulled out, and the intercepted dust is peeled off.

[0025] The entire ash baffle 12 is controlled by a lever 11 rotatably connected to the locking frame 3, such as... Figure 1 and Figure 2 As shown, the roller connected to the side of the lever 11 abuts against the groove on the ash baffle 12. When it is pushed outward, the rotating lever 11 pushes the entire ash baffle 12 to move into the pipeline connected inside the lock frame 3 to intercept the dust in the flowing flue gas.

[0026] At the same time, prevent the whole dust screen 12 from being dislocated due to impact vibration caused by air flow. The top of the dust screen 12 is screw-connected with a knob 14, the end of the knob 14 is fixedly connected with a pressing ring 15, and the limiting block 13 is fixed on the lock frame 3 through bolts, and the rubber block is fixed on one side of the limiting block 13. When the position of the push rod 11 is fixed, the knob 14 on the side of the dust screen 12 is rotated to push the whole pressing ring 15 to contact the rubber pad on the limiting block 13. The position of the dust screen 12 is limited by the friction between the pressing ring 15 and the rubber pad, so as to prevent the dislocated dust screen 12 from reducing the dust interception effect.

[0027] Since the dust screen 12 can move, it provides effective space for subsequent repair and cleaning of the dust screen 12. At the same time, the dust screen 12 can intercept large particles in the exhaust pipe 1, reduce the load of the subsequent dust collector, and prolong the effective working time of the whole dust collector.

[0028] In view of the high dust content, large particles and high temperature of the flue gas at the rear of the ash stirrer, the long-term effect is high load for the dust collector without cooling;

[0029] Therefore, as shown in Figure 3 and Figure 5 , the whole cooling and intercepting sleeve 2 is divided into two parts. The middle part is a hollow space in the shape of a circular truncated cone. The negative pressure generated by the air flow is used to move the lower flange 7 at the whole pipe connection position. The upper flange 4 is fixedly connected on the other side. The lower flange 7 is easy to be manually moved, and the lower flange 7 is protruding on both sides. The air holes two 8 are evenly arranged on the lower flange 7.

[0030] The air holes one 5 are evenly arranged on the upper flange 4. The air holes one 5 are convenient for subsequent ventilation. When the air holes two 8 on the lower flange 7 overlap with the air holes one 5 on the upper flange 4, the overlapping area is the size of the air holes. The larger the overlapping area, the better the ventilation effect. When the air holes one 5 and the air holes two 8 completely overlap, the air outside the air holes one 5 and the air holes two 8 will be discharged into the subsequent pipeline, completing the mixing of the high-temperature flue gas, achieving cooling, reducing the negative pressure of smoking, and reducing the dust content of the extracted flue gas.

[0031] In order to avoid the opening and closing of the hole caused by the movement of the lower flange 7, the lock bolt 9 is installed on the lower flange 7, and the guide hole 6 is evenly arranged on the upper flange 4. The guide hole 6 is located outside the cooling and intercepting sleeve 2. The lock bolt 9 is penetrated and fixed to lock the movable lower flange 7, which is convenient for locking after adjusting the air holes one 5 and the air holes two 8. The overlapping area of the air holes one 5 and the air holes two 8 is adjusted according to the flowing flue gas in the exhaust pipe 1 to avoid the opening and closing of the hole caused by the movement of the lower flange 7, which affects the working environment of the ash stirrer.

[0032] The above is only an example and description of the structure of the utility model, and those skilled in the art can make various modifications or supplements to the described specific embodiments or replace them with similar ways, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, which shall belong to the protection scope of the utility model.
