Description

TECHNICAL FIELD

[0001] The utility model belongs to calcium carbide technical field relates to an automatic calcium carbide unloading and crushing system. BACKGROUND

[0002] The calcium carbide produced by the calcium carbide furnace has irregular distribution of particle size from powder to 1.2 meters in diameter, but in use, the large particle size calcium carbide needs to be unloaded and crushed. The traditional unloading and crushing adopts manual unloading and pre-crushing by a shovel truck, and the specific process is as follows: the automobile transporting calcium carbide enters the unloading position, the side door of the carriage is opened manually, the calcium carbide is horizontally pushed from the carriage plate to the ground by the shovel truck, the small pieces of calcium carbide and powder remaining on the bottom plate of the carriage are cleaned to the ground by the shovel, the large pieces of calcium carbide are lifted by the shovel truck and then thrown from the air to the ground for pre-crushing, the pre-crushing process is completed by the impact force of the calcium carbide on the ground, until the particle size of the calcium carbide is smaller than the maximum feeding particle size of the crusher, and then the calcium carbide is fed into the receiving hopper of the crusher by the shovel truck. The operation has the following disadvantages:

[0003] (1) During the process of manually opening the carriage door, accidents of calcium carbide rolling and falling to crush and injure the unloading personnel are prone to occur, which is harmful to the safety of the operators; due to the high concentration of calcium carbide dust in the workshop during unloading and crushing, long-term operation is prone to cause diseases such as pneumoconiosis;

[0004] (2) During the pre-crushing of calcium carbide, it is impossible to ensure that the particle size of the calcium carbide is completely smaller than the capacity of the crusher, which is prone to cause overloading and tripping of the crusher, and the calcium carbide receiving hopper is blocked, and the calcium carbide crushing is interrupted; the calcium carbide is prone to explosion during unloading and pre-crushing due to moisture or rain, which causes personal injury and seriously affects the stability and continuity of production operation;

[0005] (3) The calcium carbide is lifted by the shovel truck and then thrown from the air, which produces a lot of noise, vibration and dust, which not only pollutes the environment, but also seriously affects the parallax of the driver and the on-site operating personnel, and brings harm to production;

[0006] (4) Patent No. 208054492U “Device for calcium carbide unloading, feeding and crushing” discloses an unloading and crushing process, and the unloading process does not need personnel operation, but the device needs to be configured with an unloading machine, an unloading platform and an inclined slope, and cannot solve the problem of large pieces of calcium carbide blocking the conveying equipment. Once the conveying equipment is blocked, manual cleaning of calcium carbide is needed, so the investment cost is high, the land occupation is large, the production continuity is poor and the use function is lacking.

[0045] In the embodiment, the small calcium carbide hopper 2 further comprises a side plate 24 connected to the lower hopper wall plates 21, and the side plate 24 extends outwardly from the side wall of the small calcium carbide hopper 2.

[0046] In the embodiment, the small calcium carbide hopper 2 further comprises a rubber shock-absorbing pad 25 arranged on the lower surface of the side plate 24.

[0049] In the embodiment, one end of the engineering dump truck 1 is located outside the small calcium carbide hopper 2, and the other end of the engineering dump truck 1 extends into the small calcium carbide hopper 2 and is located above the grid plate 23. The engineering dump truck 1 is used to transfer the loaded calcium carbide materials and pour them into the grid plate 23 of the small calcium carbide hopper 2.

[0050] Specifically, the engineering dump truck 1 comprises a carriage and wheels arranged at the bottom of the carriage, the calcium carbide materials are loaded in the carriage, and the wheels drive the carriage and the calcium carbide materials to run to the small calcium carbide hopper 2 for unloading. The engineering dump truck 1 is a conventional commercially available product, and the principle of unloading is to lift by a hydraulic rod to unload the goods automatically.

[0051] In the embodiment, the automatic calcium carbide unloading and crushing system further comprises a falling prevention wall 5 arranged outside the calcium carbide small hopper 2.

[0052] The specific process of the automatic calcium carbide unloading and crushing system in operation is as follows.

[0053] The purchased calcium carbide material is loaded on the engineering dump truck 1, and then the engineering dump truck 1 moves and approaches the surrounding of the calcium carbide hopper 2, and the wheels of the engineering dump truck 1 are in contact with the falling prevention wall 5 to support and position the engineering dump truck 1; then the engineering dump truck 1 works to unload, so that the calcium carbide material in the carriage of the engineering dump truck 1 enters the grid plate 23 in the calcium carbide hopper 2 under the action of gravity, and the calcium carbide material with a particle size greater than the grid hole falls into the lower end of the calcium carbide hopper 2 through the grid hole; in order to prevent the grid beam 231 from being damaged due to excessive stress, the grid gasket plate 22 is installed on the hopper wall plate 21 to prolong the service life of the equipment; the large calcium carbide material rolling from the carriage collides with the grid beam 231, and the calcium carbide material is more easily crushed by the tapered tip 232 on the grid beam 231, and the crushed calcium carbide material with a reduced particle size falls into the lower end of the calcium carbide hopper 2 through the grid hole on the grid plate 23; part of the relatively hard calcium carbide material is not crushed by the tapered tip 232 and has a relatively large particle size and is still on the grid plate 23, at this time, the engineering manipulator 3 is started and the calcium carbide material not crushed and with a relatively large particle size is pre-crushed until the particle size of the calcium carbide material is smaller than the size of the grid hole, so that the calcium carbide material passes through the grid hole and also enters the lower end of the calcium carbide hopper 2, and finally the crushed calcium carbide is conveyed to the crusher 6 through the heavy plate conveyor 4 for further crushing.

[0054] In implementation, the transmission members of the heavy plate conveyor 4 are all made of steel, and the main vulnerable parts are made of high-manganese forged process, which can withstand the harsh working conditions for a long time.

[0055] The crushing system can ensure that the particle size of the calcium carbide entering the heavy plate conveyor 4 and the crusher 6 is smaller than the grid hole of the grid plate 23, completely eliminates the situation that the large particle size of the calcium carbide causes abnormal shutdown of the production system and damage to the heavy plate conveyor and the crusher, thereby prolonging the service life of the equipment and improving the production efficiency.

[0056] The automatic calcium carbide unloading and crushing system can also be used for unloading and pre-crushing of other solid materials, such as unloading and pre-crushing of ores and gravel.

[0057] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit them, and although the present application has been described in detail with reference to the preferred embodiments. Those skilled in the art should understand that the technical solutions of the present application can still be modified or equivalently replaced, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present application.
