[0002] The heat medium heating equipment is an important part of the polyester process. Its operation mode is that fuel burns in the furnace, and the refrigerant enters the heat medium furnace in the form of a coil and is heated to form a primary heat medium loop. The high-temperature heat medium in the primary heat medium loop is sent to heating users such as reactors for use, and then returns to the primary heat medium loop to form a secondary heat medium loop. The heat medium is recycled during the whole heating process.

[0003] The high-level tank, also known as the expansion tank, mainly functions to absorb the expansion amount of the heat medium, balance the heat medium pipe system, exhaust air, drain water, supply oil safely, and prevent the heat medium from oxidizing and deteriorating.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a polyester heat medium high-level tank with a dredging device as Figures 1-4 shown, which includes a high-level tank body 1. The high-level tank body 1 is composed of a high-level tank main body 101 and a plurality of connecting pipes 102. The plurality of connecting pipes 102 are fixedly inserted and connected to the outer wall of the high-level tank main body 101. A dredging mechanism 2 is arranged inside one of the connecting pipes 102. The dredging mechanism 2 is used to discharge foreign matters inside the connecting pipe 102;

[0027] The dredging mechanism 2 includes an insertion tube 201. At the top of the insertion tube 201, there is a force - applying ring 202. The force - applying ring 202 facilitates the staff to apply force to drive the insertion tube 201 in and out of the connecting pipe 102. On the outer wall of the circular grip rod of the force - applying ring 202, evenly - distributed friction lines are provided to increase the friction force between the staff's palm and it. The bottom of the force - applying ring 202 is fixedly connected to the top of the insertion tube 201. On the front of the insertion tube 201, there is a blower 203. On the back of the blower 203, there is a connection assembly 209. The connection assembly 209 is used for the connection work between the blower 203 and the insertion tube 201. The connection assembly 209 includes a socket ring 2091. The socket ring 2091 is fixedly sleeved on the outer wall of the insertion tube 201. On the front of the socket ring 2091, there is a mounting plate 2092. The blower 203 is fixedly installed on the front of the mounting plate 2092. At the output end of the blower 203, there is a straight tube 204. On the front of the mounting plate 2092, there is a flow meter 210. The flow meter 210 facilitates the staff to understand how much gas is filled in the expansion airbag 207 and the size of the expansion airbag 207. The flow meter 210 is fixedly installed on the outer wall of the straight tube 204. The bottom end of the straight tube 204 is fixedly connected to the output end of the blower 203. At the top of the straight tube 204, there is an air delivery pipe 205. One end of the air delivery pipe 205 is fixedly connected to the top of the straight tube 204, and the other end of the air delivery pipe 205 is fixedly inserted and connected to the inner wall of the force - applying ring 202. The air delivery pipe 205 is communicated with the inside of the insertion tube 201. At the bottom end of the insertion tube 201, there is an inner tube 206. The inner tube 206 is fixedly connected to the bottom end of the insertion tube 201. A plurality of air outlet holes are provided on the outer wall of the inner tube 206. An expansion airbag 207 is sleeved on the outer wall of the inner tube 206. The expansion airbag 207 is made of cowhide. When the external switch of the blower 203 is turned on, the blower 203 will fill the inside of the expansion airbag 207 with gas through the straight tube 204, the air delivery pipe 205, the insertion tube 201, the inner tube 206 and the air outlet holes. The expansion airbag 207 is fixedly sleeved on the outer wall of the insertion tube 201. An occlusion assembly 211 is sleeved outside the insertion tube 201. The occlusion assembly 211 plays a role in protecting the expansion airbag 207. The occlusion assembly 211 includes a connection ring 2111. The connection ring 2111 is fixedly sleeved on the outer wall of the insertion tube 201. Uniformly - distributed external threads are provided on the outer wall of the connection ring 2111. An adjustment ring 2112 is thread - connected to the outer wall of the connection ring 2111. When the adjustment ring 2112 rotates clockwise outside the connection ring 2111, it will drive the occlusion tube 2113 to gradually approach the socket ring 2091. When the adjustment ring 2112 rotates counter - clockwise outside the connection ring 2111, it will drive the occlusion tube 2113 to gradually approach the breakthrough block 208. The bottom of the adjustment ring 2112 is fixedly connected to the occlusion tube 2113. The outer diameter of the occlusion tube 2113 is the same as the maximum diameter of the breakthrough block 208. When the occlusion tube 2113 can be closely attached to the top of the breakthrough block 208, at the bottom of the expansion airbag 207, there is a breakthrough block 208.The breakthrough block 208 allows the staff to more easily penetrate the foreign matter in the connecting pipe 102 by inserting the tube 201. The breakthrough block 208 is fixedly connected to the bottom end of the inner tube 206.

[0028] Working principle of this utility model:

[0029] When the connecting pipe 102 of the polyester heat medium high-level tank is blocked by foreign matter, firstly, the force ring 202 is used to drive the dredging mechanism 2 to move to the opening of the connecting pipe 102, and then the insertion tube 201 is inserted into the connecting pipe 102 blocked by the foreign matter with the breakthrough block 208 as the tip. When the expansion airbag 207 breaks through to the back of the foreign matter, the adjusting ring 2112 is rotated clockwise. The adjusting ring 2112 rotating clockwise outside the connecting ring 2111 will drive the shielding tube 2113 to gradually approach the sleeve ring 2091. When the shielding tube 2113 cannot shield the expansion airbag 207, the adjusting ring 2112 will rotate clockwise. When the external switch of the blower 203 is turned on, the blower 203 will fill the interior of the expansion airbag 207 with gas through the straight pipe 204, the gas pipe 205, the insertion tube 201, the inner tube 206 and the air outlet. When the expansion airbag 207 is completely in contact with the inner wall of the connecting pipe 102, the insertion tube 201, the expansion airbag 207 and the breakthrough block 208 are driven to separate from the connecting pipe 102 through the force ring 202. In the above process, foreign matter in the connecting pipe 102 will be brought out by the expansion airbag 207, thereby improving the work quality of the polyester heat medium high-level tank pipeline dredging work.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
