Description

TECHNICAL FIELD

[0002] The shell type heat exchanger is mainly composed of a shell, a tube bundle, a baffle plate and a tube cover, etc. The shell is a cylindrical shell, which provides a flow space for the fluid outside the tube. The tube bundle is fixed in the shell by a large number of heat transfer tubes through the tube plate. The heat source fluid flows through the internal tube, while the cooling fluid flows through the outside of the shell. When the heat source fluid flows through the tube, the heat is transferred to the outer surface of the tube wall through the tube wall. At the same time, the cooling fluid flows outside the shell and absorbs the transferred heat, which causes the heat source fluid to cool down to achieve heat exchange.

[0003] Because the cover plate of the heat exchanger directly contacts with the heat source fluid, it is necessary to spray the anticorrosive material on the tube cover of the heat exchanger during the processing of the heat exchanger. Since the tube bundle of the heat exchanger usually protrudes from one side of the tube cover, the worker also needs to spray the anticorrosive material on the protruding tube bundle. Since the number of tube bundles is large and closely distributed, it is difficult for the worker to quickly and uniformly spray the anticorrosive material on the tube wall of the tube bundle, and in the long-term spraying process, it will cause harm to the worker's body.

[0029] The support unit 100 comprises a support seat 101 and a mounting seat 102 slidingly arranged on the top of the support seat 101, and the support seat 101 is fixedly connected with an electric telescopic rod 103 on one side, and the output end of the electric telescopic rod 103 is fixedly connected on one side of the bottom of the mounting seat 102, and the top of the mounting seat 102 is provided with a mounting groove, and the mounting groove of the mounting seat 102 is placed with a heat exchanger;

[0030] The spraying unit 200 comprises a support plate 201 fixedly connected on the top of the support seat 101, and the support plate 201 is fixedly installed with a servo motor 202 on one side, and the output end of the servo motor 202 is fixedly connected with a protective shell 203, and the inner wall of the protective shell 203 is fixedly connected with a fixed plate 204, and the fixed plate 204 is rotatably connected with three double-groove pulleys 205 through transmission belts 206, and the side wall of each double-groove pulley 205 is fixedly connected with a T-shaped plate 207, and the side of each T-shaped plate 207 is fixedly connected with a spray head 208, and the outer wall of the protective shell 203 is fixedly connected with a driving motor 209, and the output end of the driving motor 209 penetrates through the protective shell 203 and is fixedly connected with one of the double-groove pulleys 205, and the spraying unit 200 further comprises a conveying assembly 210 for conveying anticorrosive material to the spray head 208.

[0031] The installation groove of the top of the mounting base 102 is semicircular for placing the heat exchanger, the mounting base 102 can be pushed towards the protective shell 203 by the electric telescopic rod 103 to make the pipe cover of the heat exchanger contact with the opening of the protective shell 203, the beam pipe is in U shape and protrudes from one side of the pipe cover towards the two ends of the protective shell 203, the protective shell 203 can be driven to rotate by the servo motor 202, the corrosion-resistant material liquid can be delivered into the spray head 208 by the delivery assembly 210, when the port of the beam pipe is transversely aligned with the spray head 208, the spray head 208 can be rotated to quickly coat a layer of corrosion-resistant material on the vertical surface of the cover plate, and the spray head 208 can also spray a layer of corrosion-resistant material on the inner wall of the opening of the beam pipe;

[0032] Due to the transverse spraying, it is difficult to uniformly coat the corrosion-resistant coating on the outer wall of the beam pipe, at this time, the driving motor 209 drives the double-groove pulley 205 in the middle to rotate, the double-groove pulley 205 in the middle drives the remaining two double-groove pulleys 205 to rotate in the same direction through the two transmission belts 206, thereby the double-groove pulleys 205 drive the T-shaped plate 207 and the spray head 208 to deflect slightly, so that the spray head 208 is in an inclined state, thereby the spray head 208 can fully spray the corrosion-resistant material on the outer wall of the beam pipe, the driving motor 209 repeatedly rotates in the forward and reverse directions to make the multiple spray heads 208 swing back and forth, so that the spray head 208 can be in an inclined state to coat a layer of corrosion-resistant coating on the outer wall of the beam pipe from the side;

[0033] After coating, stop spraying and turn off the driving motor 209 and the servo motor 202, then the electric telescopic rod 103 pulls the mounting base 102 to make it no longer contact with the protective shell 203, thereby the pipe cover and the beam pipe can be quickly and uniformly coated with the corrosion-resistant coating to reduce the burden of workers.

[0034] Specifically, the delivery assembly 210 comprises a storage box 2101 fixedly connected to one side of the protective shell 203, the outer wall of the storage box 2101 is fixedly connected with a filling pipe 2102, one side of the storage box 2101 is fixedly provided with a water pump 2103, one side of the water pump 2103 is fixedly connected with a delivery pipe 2104, the pipe wall of the delivery pipe 2104 is fixedly connected with a plurality of hoses 2105, each hose 2105 penetrates through the protective shell 203 and is fixedly connected with a corresponding spray head 208, one side of the storage box 2101 is fixedly installed with an electric telescopic lever 2106, the output end of the electric telescopic lever 2106 penetrates into the inner cavity of the storage box 2101 and is fixedly connected with a piston plate 2107.

[0035] The filling pipe 2102 is sleeved with a valve for controlling the closing of the filling pipe 2102, the filling pipe 2102 is used for adding the corrosion-proof material into the storage tank 2101, the water pump 2103 is used for conveying the corrosion-proof material in the storage tank 2101 into the conveying pipe 2104, the conveying pipe 2104 can convey the corrosion-proof material into the spray head 208 through the hose 2105, the storage tank 2101 is driven to rotate by the protective shell 203, and the corrosion-proof material in the storage tank 2101 can be prevented from being deposited;

[0036] During the extraction of the water pump 2103, the electric telescopic rod 2106 pushes the piston plate 2107 to compress the space containing the corrosion-proof material, the piston plate 2107 is sealed with the inner wall of the storage tank 2101, so that the side of the piston plate 2107 away from the electric telescopic rod 2106 is always filled with the corrosion-proof material, so as to ensure that the water pump 2103 can continuously extract, the capacity of the storage tank 2101 is large, and the corrosion-proof material can be provided for multiple heat exchangers at a time, a certain amount of the corrosion-proof material in the storage tank 2101 needs to be reserved, so as to avoid insufficient pressure when the water pump 2103 extracts, causing uneven spraying, when a part of the amount of the corrosion-proof material in the storage tank 2101 is left, the electric telescopic rod 2106 needs to pull the piston plate 2107 to be located on the side away from the filling pipe 2102, and the corrosion-proof material needs to be replenished, so as to continue to coat.

[0037] In addition, the outer wall of the protective shell 203 is fixedly sleeved with the bearing one 211, one side of the bearing one 211 is fixedly connected with the rubber ring 212, the output end of the servo motor 202 is fixedly sleeved with the bearing two 213, the outer wall of the bearing two 213 is fixedly sleeved with the vertical plate 214, and the vertical plate 214 is fixedly connected to the top of the support seat 101.

[0038] When the pipe cover approaches the protective shell 203, the pipe cover is in contact with the rubber ring 212, the pipe cover can be protected by the rubber ring 212, so that the pipe cover does not contact the protective shell 203, when the protective shell 203 rotates, the inner ring of the bearing one 211 rotates synchronously with the protective shell 203, the rubber ring 212 is fixedly connected to the side wall of the outer ring of the bearing one 211, so that the outer ring of the bearing one 211 does not rotate through the friction force of the rubber ring 212, and the vertical plate 214 and the bearing two 213 are used for auxiliary supporting the output end of the servo motor 202, so as to improve the stability of the servo motor 202 during rotation.

[0039] Further, one side of the mounting seat 102 is fixedly connected with the collection box 104, and one side of the collection box 104 is fixedly connected with the discharge pipe 105.

[0040] When the coating is finished, the electric telescopic rod 103 pulls the mounting seat 102 so that it is no longer in contact with the protective shell 203, and the dropped anticorrosive material at the opening of the tube cover and the protective shell 203 can be recycled through the collection box 104 to avoid polluting the support seat 101. The outer wall of the discharge pipe 105 is sleeved with a valve, and the collected anticorrosive material in the collection box 104 is discharged through the discharge pipe 105.

[0041] Further, a pair of rollers 106 are rotatably connected to the bottom of the mounting seat 102, and each roller 106 is in contact with the top of the support seat 101.

[0042] The rollers 106 can assist in supporting the mounting seat 102 to improve the stability of the mounting seat 102. When the electric telescopic rod 103 moves the mounting seat 102, the rollers 106 roll on the support seat 101 to improve the smoothness of the movement of the mounting seat 102.

[0043] During use, the heat exchanger is placed in the mounting groove on the top of the mounting seat 102, and then the electric telescopic rod 103 pushes the mounting seat 102 to move towards the protective shell 203 so that the tube cover of the heat exchanger is in contact with the rubber ring 212. Then the protective shell 203 is driven to rotate by the servo motor 202, and the anticorrosive material liquid is transported into the spray head 208 by the conveying assembly 210. When the plurality of spray heads 208 are in a horizontal state, the spray head 208 can quickly spray a layer of anticorrosive material on the vertical surface of the cover plate and the inner wall of the opening of the beam tube.

[0044] Then the driving motor 209 is repeatedly driven to rotate in the forward and reverse directions with a small amplitude, so that the plurality of spray heads 208 can swing back and forth, so that the spray head 208 can be in an inclined posture to coat a layer of anticorrosive coating on the side of the beam tube. After the coating is finished, the spraying is stopped, and the driving motor 209 and the servo motor 202 are turned off. Then the electric telescopic rod 103 pulls the mounting seat 102 so that it is no longer in contact with the rubber ring 212, so that the tube cover and the beam tube can be quickly and uniformly coated with an anticorrosive coating, thereby reducing the burden on workers. The collected anticorrosive material in the collection box 104 can be discharged through the discharge pipe 105.
