Description

Technical Field

[0001] The utility model relates to the field of heat carrier boilers, in particular to a quick-assembly structure of an organic heat carrier boiler. Background Art

[0002] An organic heat carrier boiler refers to a new type of heat energy conversion equipment whose heat carrier is high-temperature heat-conducting oil (also called hot coal body, heat carrier). Therefore, an organic heat carrier boiler is also called a heat-conducting oil boiler. The capacity of the furnace is usually expressed in "MW" (megawatt). The advantage of an organic heat carrier furnace (also called a heat-conducting oil furnace) is that it has "high temperature and low pressure" and runs smoothly, and is therefore widely used.

[0003] The utility model patent with publication number CN 213514432 U discloses a heat carrier boiler, including a fixed seat and a boiler body, a feed port and a discharge port are arranged at the upper end of the boiler body, quick-release clamps are arranged at the upper ends of the feed port and the discharge port, a heat conduction pipe is arranged between the feed port and the discharge port, a fixed plate is arranged on the outer end surface of the heat conduction pipe, a slag discharge port is arranged at the bottom of the boiler body, a smoke exhaust port is arranged at the top of the boiler body, a smoke exhaust pipe is arranged at the outer end of the smoke exhaust port, a motor is arranged on the fixed seat, and rollers are arranged at the front and rear ends of the fixed seat.

[0004] The above utility model tilts and props up the boiler body through a fixed seat, and then drives the boiler body to rotate through a motor, so that the slag in the boiler body can be discharged along the fixed plate and the auger blades, which greatly improves the convenience of boiler cleaning. By setting a filter plate in the smoke exhaust port and an activated carbon filter in the smoke exhaust pipe, the environmental protection performance of the equipment is greatly enhanced. However, the heat carrier in the above heat carrier boiler is of fixed size and cannot be increased or decreased as needed, so that the heat carrier boiler needs to be redesigned for each project under the change of operating parameters, which is time-consuming and labor-intensive. Therefore, it is necessary to invent an organic heat carrier boiler quick-install structure to solve the above problems. Utility Model Content

[0020] Specifically, two adjacent groups of connecting tubes 5 are connected by a connecting tube 7, and second protrusions 11 are fixed at both ends of the connecting tube 7. Two second sealing rings 12 are bonded to the lower surface of the second protrusion 11. The two second sealing rings 12 are arranged in a concentric circle shape, and the two second sealing rings 12 are staggered with the first sealing ring 10. The second sealing rings 12 cooperate with the first sealing ring 10 to play a good sealing role.

[0021] More specifically, both ends of the connecting pipe 7 are provided with connecting components 8, and the connecting components 8 are connected to the connecting head 6. The connecting components 8 include a sleeve 13, and the upper end of the sleeve 13 is sleeved on the outer sides of the two ends of the connecting pipe 7. An internal thread 14 is provided on the inner wall of the lower end of the sleeve 13, and the internal thread 14 corresponds to the external thread provided on the peripheral side of the first convex head 9.

[0022] Working principle of this utility model:

[0023] When the device needs multiple modular heat exchange units, two adjacent heat exchange units are connected through the connecting pipe 7, and the second protrusion 11 on the connecting pipe 7 is aligned with and fitted to the first protrusion 9 on the connecting pipe 5, so that the first sealing ring 10 and the second sealing ring 12 cooperate to play a sealing role, and then the sleeve 13 is rotated to connect the internal thread 14 on the sleeve 13 with the external thread on the first protrusion 9 until the upper end of the sleeve 13 contacts the top of the second protrusion 11, which plays a limiting role. At this time, the lower end of the sleeve 13 is located below the first protrusion 9. The connecting pipe 7 and the connecting pipe 5 are tightly fitted together, and then the knob 17 is turned to drive the screw 16 to rotate.
