Description

TECHNICAL FIELD

[0001] The utility model relates to the field of acetylene production, especially to the calcium carbide feeding device for acetylene production. BACKGROUND

[0002] In acetylene production, the calcium carbide used is calcium carbide, which is an important chemical raw material. It appears as gray, brownish yellow or black block solid. Calcium carbide reacts with water to produce acetylene and calcium hydroxide. Calcium carbide plays a key role in the production of acetylene. The quality of calcium carbide has a great influence on the production efficiency and quality of acetylene. High-quality calcium carbide usually has high purity and appropriate particle size to ensure that the reaction can proceed smoothly and the acetylene gas produced has high purity. At the same time, attention should be paid to the storage and transportation of calcium carbide, because calcium carbide reacts with water to produce flammable acetylene gas, which may cause danger.

[0033] With reference to the accompanying drawings, Figure 2 ​, the vibrating mechanism 4 comprises a double-shaft motor 41 fixedly connected to the top end of the outer wall of the support 5, a contact block 42 rotatably connected to the outer side wall of the external frame 1, and output shafts fixedly connected to the left and right sides of the double-shaft motor 41 and having the contact block 42. The double-shaft motor 41 is a prior art, and both sides thereof are provided with output shafts. The double-shaft motor 41 is started to enable the two groups of contact blocks 42 to rotate synchronously. The outer wall of the contact block 42 is in contact with the outer wall of the surface protrusion of the sliding block A 44, and the contact between the two enables the rotation of the contact block 42 to push the sliding block A 44 to move horizontally inside the external frame 1. The contact block 42 is slidably connected to the inner side wall of the external frame 1 and penetrates and is slidably connected to the surface of the guide column 45. One end of the limiting spring 43 is fixedly connected to the outer wall of the sliding block A 44, and the other end thereof is fixedly connected to the inner side wall of the external frame 1. The limiting spring 43 is used to enable the sliding block A 44 to be automatically reset by the elastic action of the limiting spring 43 after the surface protrusion of the sliding block A 44 is no longer contacted by the rotation of the contact block 42, so as to reciprocate, so that the calcium carbide in the storage barrel 3 does not block the discharge port during discharging.

[0034] Referring to Figure 2 , the sliding block A 44 is slidably connected to the inner side wall of the external frame 1, the sliding block B 47 is slidably connected to the inner side wall of the external frame 1, and the outer wall of the sliding block B 47 is fixedly connected to the outer wall of the storage barrel 3. The inner side of the external frame 1 is provided with a guide rod, so that the sliding block B 47 can only move linearly up and down, so as to drive the storage barrel 3 to move up and down. The inner side wall of the external frame 1 is elastically connected to the sliding block A 44 by the limiting spring 43, and the inner side wall of the external frame 1 is fixedly connected to the guide column 45. The surface of the sliding block A 44 is provided with a protrusion, the outer wall of the protrusion of the sliding block A 44 is hingedly connected to the hinge rod 46, and the end of the hinge rod 46 away from the sliding block A 44 is hingedly connected to the sliding block B 47. After the surface protrusion of the sliding block A 44 is extruded by the rotation of the contact block 42, it will move horizontally, so as to push the sliding block B 47 through the hinge rod 46 to drive the storage barrel 3 to move up and down, so that the storage barrel 3 can reciprocatingly move up and down, thereby avoiding the density of the calcium carbide in the storage barrel 3 being too high during discharging, thereby causing the discharge port to be blocked.

[0035] Referring to Figure 3 and Figure 4The degradation assembly 9 comprises two sets of connecting frames 91 slidingly connected to the inner wall of the bottom end of the external frame 1. The inner wall of the bottom end of the external frame 1 is provided with guide grooves matching the two sides of the connecting frame 91, so that the connecting frame 91 can only move up and down on the inner wall of the external frame 1 and cannot be separated from the inner wall. Meanwhile, when the external frame 1 as a whole is lowered to be attached to the equipment charging port, the connecting column 92 will move upward on the inner wall of the external frame 1 until the discharge port of the storage barrel 3 is attached to the charging port. A plurality of connecting columns 92 are fixedly connected between the two sets of connecting frames 91. By arranging the connecting column 92 between the two sets of connecting frames 91, the water sprayed at the spraying ring 7 can be adsorbed on the surface of the connecting column 92, so as to adsorb the dust raised at the discharge port of the storage barrel 3, thereby avoiding dust raising. The outer wall of the bottom connecting frame 91 is fixedly connected with a blowdown pipe 93, and the inside of the bottom connecting frame 91 is provided with a cavity, so that the water sprayed by the spraying ring 7 and the grey water adsorbed on the surface of the connecting column 92 can be discharged outward through the blowdown pipe 93.

[0036] With reference to Figure 3 Figure 4 The limiting assembly 6 comprises an insertion block 61 elastically connected to the inner wall of the support 5 through a return spring 62. One end of the return spring 62 is fixedly connected to the inner wall of the support 5, and the other end of the return spring 62 is fixedly connected to the surface of the insertion block 61. The return spring 62 serves to automatically reset the position of the insertion block 61 after being pulled outward. The insertion block 61 penetrates and slidingly connects to the inner wall of the support 5. The surface of the connecting frame 91 is provided with a through hole, and the bottom end of the outer wall of the insertion block 61 is inserted into the inner wall of the through hole of the connecting frame 91. The insertion block 61 and the connecting frame 91 are inserted between each other, so as to fix the position of the connecting column 92 moving upward at the bottom end of the inner wall of the external frame 1, thereby facilitating the maintenance of the bottom discharge port of the storage barrel 3 by the workers.

[0037] Working principle: The top end of the outer wall of the external frame 1 is fixedly connected with four lifting lugs 2. The external frame 1 as a whole can be transported to the charging port by using a lifting device such as a crane. The inner side wall of the external frame 1 is provided with a storage barrel 3. The top end of the storage barrel 3 is provided with a cover plate, which can be opened to supplement the ilmenite. The bottom end is provided with an electrically controlled discharge port, which can automatically discharge when transported to the charging port.

[0038] ​When the storage barrel 3 is discharged, the biaxial motor 41 can be started to drive the two groups of contact blocks 42 to rotate synchronously. When the contact blocks 42 rotate, the sliding block A 44 is pushed to move horizontally in the outer frame 1, and the limiting spring 43 is elastically compressed. After the contact blocks 42 cancel the extrusion on the sliding block A 44, the sliding block A 44 is automatically reset by the elastic action of the limiting spring 43. Meanwhile, when the surface protrusion of the sliding block A 44 is extruded by the rotation of the contact blocks 42, it moves horizontally, pushes the sliding block B 47 through the hinged rod 46 to drive the storage barrel 3 to move up and down, so that the storage barrel 3 can move up and down reciprocally, avoiding that the density of the calcium carbide in the storage barrel 3 is too high to cause the discharge port to be blocked when the storage barrel 3 is discharged.

[0039] When the outer frame 1 is lowered to be attached to the device feeding port, the connecting column 92 moves upward in the inner wall of the outer frame 1, until the discharge port of the storage barrel 3 is attached to the feeding port. The water sprayed from the spraying ring 7 is adsorbed on the surface of the connecting column 92 to adsorb the dust raised at the discharge port of the storage barrel 3, avoiding dust raising. The bottom connecting frame 91 is internally provided with a cavity, so that the water sprayed by the spraying ring 7 and the dust water adsorbed on the surface of the connecting column 92 can be discharged outward through the drain pipe 93. After the connecting frame 91 drives the connecting column 92 to move upward in the bottom end of the inner wall of the outer frame 1, the plug-in block 61 is inserted into the through hole to fix the position of the connecting frame 91, facilitating the maintenance of the bottom discharge port of the storage barrel 3 by the workers.

[0040] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
