Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to a heat exchanger accessory cleaning device. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, and are widely used.

[0003] After prolonged use, heat exchangers accumulate a large amount of dirt on their internal components, such as plates. This dirt affects the heat exchanger's efficiency and reduces its service life, thus requiring regular cleaning of the components. However, existing heat exchanger component cleaning devices suffer from incomplete cleaning and low efficiency, failing to meet the needs of actual production. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a heat exchanger component cleaning device to solve the problems in the background art.

[0005] A heat exchanger accessory cleaning device includes a cleaning tank and casters at the four corners of the bottom of the cleaning tank. A high-pressure water pump is installed on the side wall of the cleaning tank. A left-right reciprocating cleaning assembly is installed on the cleaning tank. A plate limiting rotation assembly is installed on the cleaning tank.

[0006] The reciprocating cleaning assembly includes an L-shaped bracket fixed on the cleaning tank, a reciprocating mechanism mounted on the L-shaped bracket, and a cleaning mechanism fixed on the reciprocating mechanism.

[0007] The reciprocating mechanism includes a U-shaped support fixed on an L-shaped bracket, a reciprocating lead screw movably connected between the left and right ends of the U-shaped support via bearings, and a pair of guide slides.

[0008] A threaded sleeve is screwed into the external thread of the reciprocating lead screw, and a sliding sleeve that slides left and right is sleeved on the slide rod.

[0009] A mounting base is fixedly provided between the two sliding cylinders and the threaded sleeve. A geared motor is installed at the top of the U-shaped support, and the output end of the geared motor is fixedly connected to the reciprocating lead screw.

[0010] The cleaning mechanism includes a spray pipe fixed on a mounting base, with a plurality of nozzles arranged in an array on the spray pipe, and the spray pipe is connected to a high-pressure water pump via a hose.

[0011] The plate limiting and rotating assembly includes a left limiting mechanism movably mounted on the left inner side wall of the cleaning tank via bearings, a right limiting mechanism movably mounted on the right inner side wall of the cleaning tank, and a reduction motor fixed to the right side wall of the cleaning tank.

[0012] The output shaft of the geared motor is fixedly connected to one end of the right limit mechanism.

[0013] The right limiting mechanism includes a U-shaped seat fixed to the right inner wall of the cleaning tank by a bearing. The U-shaped seat is provided with a U-shaped limiting rod that slides up and down. A limiting head is fixedly provided at one end of the U-shaped limiting rod inside the U-shaped seat, and a spring is sleeved on the U-shaped limiting rod inside the U-shaped seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Left-right reciprocating cleaning: By setting up a left-right reciprocating cleaning component, the geared motor drives the reciprocating screw to rotate, causing the threaded sleeve to move left and right on the reciprocating screw, which in turn drives the mounting base and the spray nozzle to move left and right back and forth. The spray nozzle thoroughly cleans the heat exchanger accessories, improving cleaning efficiency and cleaning effect.

[0016] Plate limiting rotation: The plate limiting rotation assembly can limit the heat exchanger plates. At the same time, the geared motor drives the right limiting mechanism to rotate, causing the plates to rotate. In conjunction with the left and right reciprocating cleaning assembly, the plates can be cleaned from all directions, making the cleaning more thorough. Attached Figure Description

[0031] This implementation plan addresses the technical problems existing in the prior art, such as the aforementioned background technology disclosure that "after prolonged use, heat exchangers accumulate a large amount of dirt on their internal components, such as plates, which affects the heat exchange efficiency and reduces their service life. Therefore, it is necessary to clean the heat exchanger components regularly. However, existing heat exchanger component cleaning devices suffer from incomplete cleaning and low efficiency, failing to meet the needs of actual production." In practical terms, this problem is clearly real and difficult to solve. Therefore, to address this technical problem, a heat exchanger component cleaning device is provided.
