Description

Technical Field

[0001] The utility model belongs to the technical field of material suction overhead cranes, and particularly relates to a cooling system for a material suction and discharge overhead crane. Background Art

[0002] The material suction and discharge overhead crane is a special equipment in the roasting workshops of industries such as carbon, graphite, and anode materials. The material suction and discharge overhead crane mainly includes seven major parts: a bridge, a trolley running mechanism, a crab running mechanism, a material suction and discharge system, a cooling system, a dust removal system, and an electric control system. When using a suction pipe to convey high-temperature filling materials into the storage tank, it is necessary to cool the high-temperature materials through a cooling system. In the prior art, the high-temperature materials are often cooled by adding a cooling fan. However, while the cooling fan cools the high-temperature materials, it will also increase the material dust, which brings greater pressure to the dust removal system and requires frequent replacement of the dust removal system. This not only increases the production cost, but also increases the time for replacing and repairing equipment, reducing the production efficiency. Therefore, the material cooling effect of the overhead crane material suction system in the prior art is poor. Content of the Utility Model

[0003] The utility model aims to solve the technical problem that the existing cooling system of the material suction crane has a poor cooling effect on high-temperature materials, and provides a cooling system for a material suction and discharge crane, which includes a vertically arranged storage tank. The upper end of the storage tank is fixed on the crane. An electric control system and a traveling mechanism are arranged on the crane. The traveling mechanism can drive the crane to move freely along the traveling track. The bottom end of the storage tank is connected with an upper suction pipe, and the upper end of the storage tank is connected with a material suction system. A vertically arranged lower suction pipe is arranged below the upper suction pipe. The bottom end of the upper suction pipe is closed, and the top end of the lower suction pipe is closed. A cooling mechanism for reducing the temperature of the material is arranged between the lower suction pipe and the upper suction pipe. The cooling mechanism includes a support frame fixed at the bottom end of the crane. A vertically arranged cooling tank is fixed on the support frame. A horizontally arranged lower annular pipe is arranged at the lower end inside the cooling tank. The lower annular pipe is fixed on the inner wall of the cooling tank through a support rod. A plurality of lower horizontal pipes are communicated between the lower annular pipe and the lower suction pipe. An upper annular pipe is arranged directly above the lower annular pipe. The upper annular pipe is fixed on the inner wall of the cooling tank through a support rod. A plurality of vertically arranged vertical pipes are communicated between the upper annular pipe and the lower annular pipe. And an upper horizontal pipe is communicated between the upper suction pipe and the upper annular pipe. Under the action of the negative pressure system, the high-temperature material is sucked into the lower suction pipe, then enters the lower annular pipe through each lower horizontal pipe, then is dispersed into each vertical pipe, then converges into the upper suction pipe through the upper annular pipe and the upper horizontal pipe, and then enters the storage tank. A circulating water mechanism for cooling the material is arranged on the cooling tank. The circulating water mechanism includes a water tank fixed on the support frame. A water injection port is arranged at the top end of the water tank, and a drain port is arranged at the lower end of the water tank. A water pump is arranged between the water tank and the cooling tank. The water inlet of the water pump is connected to the lower end of the water tank through a water pipe, and the water outlet of the water pump is connected to the lower end of the cooling tank. The upper end of the cooling tank is connected to the upper end of the water tank through a water pipe. The water in the cooling tank exchanges heat with the high-temperature material in the lower annular pipe, the lower horizontal pipes, the upper annular pipe, the upper horizontal pipes and the vertical pipes. After the temperature of the high-temperature material is reduced, it enters the storage tank under the action of the negative pressure.

[0004] Preferably, the water tank is made of stainless steel which is easy to dissipate heat.

[0005] Preferably, a support column for support is fixed between the upper suction pipe and the lower suction pipe, which improves the stability of the equipment.

[0006] Preferably, the pipe diameter of the lower annular pipe is larger than that of the lower horizontal pipe.

[0007] Preferably, the number of the lower horizontal pipes is less than that of the vertical pipes, and the pipe diameter of the vertical pipes is smaller than that of the lower horizontal pipes.

[0008] Preferably, the lower annular pipe, the lower horizontal pipes, the upper annular pipe, the upper horizontal pipes and the vertical pipes are all made of stainless steel material which is easy to conduct heat exchange.

[0009] Adopting the above scheme has the following advantages:

[0010] The settings of the lower annular pipe, the lower horizontal pipe, the upper annular pipe, the upper horizontal pipe and the vertical pipe can disperse the high-temperature materials, increase the heat dissipation area of the materials in the cooling tank, and improve the heat dissipation efficiency; the setting of the water circulation mechanism can provide heat exchange water for the high-temperature materials in the cooling tank; the setting of the support column plays a supporting role for the upper suction pipe and the lower suction pipe, improving the stability.
