Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to a sedimentation tank capable of achieving self-cleaning. Background Art

[0002] In the production process of calcium carbide furnace, the generation of high-temperature furnace gas is an inevitable phenomenon. These furnace gases, whose temperature is usually between 400-900℃, are not only high in temperature, but also contain a large amount of impurities and unreacted raw materials. In order to effectively treat these furnace gases, reduce their temperature and purify the harmful substances in them, sedimentation tanks are widely used in this process. However, the purified ash produced in the purification process of calcium carbide furnace has a series of special physical properties, such as high temperature, high adhesion, light specific gravity and fine particle size. These characteristics make the purified ash easy to adhere to the inner wall of the sedimentation tank and difficult to fall off by itself. After long-term accumulation, a thick layer of ash will form on the inner wall of the sedimentation tank, which not only affects the purification efficiency of the sedimentation tank, but also may pose a threat to the safe operation of the equipment.

[0003] At present, in order to remove the purified ash adhering to the inner wall of the sedimentation tank, most factories still use the method of manually knocking the tank, which is not only inefficient and consumes a lot of manpower, but also has certain safety hazards. For this reason, we propose a sedimentation tank that can achieve self-cleaning. Utility Model Content

[0018] 1.

[0030] The fixing device 2 is arranged on the upper and lower surfaces of the can knocking device base 3 to play a supporting role.

[0031] Furthermore, three sides of the mounting frame 5 away from the sedimentation tank 1 are all provided with protective nets.

[0032] Furthermore, the knocking device 12 includes a rotating seat 7, a toggle block 8 and a gear 9. Two symmetrically arranged rotating seats 7 are fixedly connected to the upper surface of the mounting frame 5. A through groove is formed between the two rotating seats 7 corresponding to the upper surface of the mounting frame 5. A toggle block 8 is rotatably connected between the two rotating seats 7. One end of the rotating shaft of the toggle block 8 extends to one side of the rotating seat 7 and is fixedly connected to a gear 9. The gear 9 is connected to the rotating shaft of the driving motor 6 through a toothed belt.

[0033] Furthermore, one end of the toggle block 8 close to the pendulum 13 is composed of two trapezoidal splints, and one side of the toggle block 8 close to the pendulum 13 is provided with three plug-in holes 10, in which a pendulum toggle column 11 is movably plugged, and the pendulum toggle column 11 is fixed to both sides of the toggle block 8 by screws and nuts.

[0034] Furthermore, the pendulum 13 is composed of two swing rods, the angle between the two swing rods is set to be an acute angle, the swing trajectory of the swing rod at the upper end of the pendulum 13 is located between the two clamping plates on the toggle block 8, and the bottom of the swing rod at the lower end of the pendulum 13 is fixedly connected to a hammer body.

[0035] Furthermore, the fixing device 2 includes a fixing seat 14, a rotating rod 15 and a supporting plate 16. The upper surface of the knocking device base 3 is fixedly connected to the inner cavity of the mounting frame 5, and the fixing seat 14 is threadedly connected to the fixing seat 14. The lower end of the rotating rod 15 extends to the bottom of the knocking device base 3 and is rotatably connected to the supporting plate 16. The lower end of the rotating rod 15 is fixedly connected to the upper and lower surfaces of the supporting plate 16 corresponding to the upper surface of the supporting plate 16.

[0036] Furthermore, four support blocks 17 equidistantly arranged are fixedly connected to the lower surface of the support plate 16 , and the bottom surfaces of the support blocks 17 are all rough surfaces.

[0037] Working principle: When using this device to settle the high-temperature furnace gas generated by the calcium carbide furnace, first, the sewage containing suspended particles is received and processed by the sedimentation tank 1, so that the particles therein settle to the bottom of the tank under the action of gravity. The universal wheel 4 allows the base 3 of the knocking tank device to be easily moved when needed. The mounting frame 5 serves as the main structure of the entire knocking tank device 12. The drive motor 6 installed on its upper surface provides power for the knocking tank. The drive motor 6 is started. After the drive motor 6 is started, the gear 9 at one end of the toggle block 8 is driven to rotate through the toothed belt. The rotation of the gear 9 drives the toggle block 8 to rotate between the two rotating seats 7. The toggle block 8 rotates, so that the pendulum toggle column 11 between the two clamping plates of the toggle block 8 drives the pendulum 13 to swing at cyclic intervals. The pendulum 13 is composed of two swing rods. The angle design of the pendulum 13 enables the pendulum to more effectively knock the outer wall of the sedimentation tank 1 when swinging. When the pendulum 13 swings to the highest point and falls, the hammer body at its bottom knocks the sedimentation tank 1, thereby generating vibration, which helps to shake off the sediment attached to the tank wall. The fixing device 2 ensures the stability of the base 3 of the knocking tank device and the mounting frame 5 during operation. By rotating the rotating rod 15 to move downward in the fixing seat 14, the bottom support plate 16 and support block 17 are driven to move toward the ground. By moving the support plate 16 downward so that the four support blocks 17 contact the bottom surface and grasping them through the rough surface, the inertia generated by the swing of the pendulum 13 can be reduced, which causes the entire device to be away from the sedimentation tank 1.
