Description

Technical Field

[0001] The utility model relates to the technical field of condensation towers, in particular to a chemical condensation tower with strong air tightness. Background Art

[0002] Condensation towers are commonly used in the chemical production industry as cooling equipment for heat exchange. Most existing cooling towers spray hot water onto the surface of the filler to contact the cold air passing through the filler. Heat exchange occurs between the hot water and the cold air. At the same time, part of the hot water is evaporated, and finally the cooled water falls into the pool. Since heat is mainly dissipated through water evaporation, the cooling tower produces steam and loses water, resulting in a waste of water resources, which is not energy-saving and environmentally friendly.

[0003] A chemical cooling tower disclosed in a Chinese patent (CN214747354U) is equipped with a spray plate, a hot water pipe and a water pump. Hot water can be discharged into the interior of the spray plate through the hot water pipe, so that the water can be sprayed through the spray plate, so that it contacts with the air to dissipate heat, and the dissipated water can fall into the interior of the cooling tower body. By arranging a motor, fan blades, ventilation holes, a protective cover and a mesh plate, when the motor rotates, it can drive the fan blades to rotate, thereby dissipating heat from the interior of the cooling tower body.

[0004] The above-mentioned public technology does not have an inspection port, which can facilitate the maintenance and sanitary treatment of the inside of the condensation tower by the staff. However, the provision of the inspection port will result in an exposed channel in the condensation tower. The channel is always exposed, so the liquid inside the condensation tower will evaporate and overflow through the channel, which will also cause waste. Utility Model Content

A ratchet column is provided in the wrench, and the ratchet column can be clamped on the ratchet by a spring, so that the wrench can be kept in a fixed state at all times to prevent accidental injury caused by the wrench being reset due to the weight of the sealing door.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] Reference Figure 1-5, is an embodiment of the utility model, which provides a chemical condensation tower with strong airtightness. By setting an inspection port on the condensation tower, it is convenient to maintain the condensation tower. At the same time, a seal is set on the inspection port through a connecting rod mechanism, so that the door can open and close the sealed port to prevent the liquid inside the condensation tower from evaporating and escaping from the inspection port. Specifically, it includes a tower body 100, the main component of the condensation tower, and an inspection port for workers to maintain the tower body 100 and install other equipment is opened at the lower end of the front surface of the tower body 100. The inspection port is equipped with a sealing door 200 that covers the inspection port to ensure airtightness.

[0028] A ratchet 203 with a limit position is fixed at the edge of the inspection port, and a wrench 201 for driving the sealing door 200 to open and close is rotatably connected to the center of the outer side of the ratchet 203 by a bearing. A ratchet column 202 is provided inside the wrench 201 to ensure that the wrench 201 is fixed, and the ratchet column 202 is engaged with the ratchet 203. A connecting rod 204 for transmitting force when the wrench 201 moves is fixed on the lower surface of the outer side of the wrench 201, and a fixing piece 204a is provided at the end of the connecting rod 204 to be connected to the sealing door 200. A switch 202a is integrally connected to the surface to drive the ratchet 202 to disengage from the ratchet 203, and a rectangular through hole is provided on the front surface of the wrench 2201 for the switch 202a to move up and down. A spring 202b is sleeved on the ratchet 202 and above the switch 202a. The spring 202b ensures that the ratchet 202 is always engaged with the ratchet 203 in the absence of external interference. The top of the spring 202b contacts the inner top wall of the wrench 201, and a protruding short column is provided on the ratchet 202 to contact the bottom end of the spring 202b.

[0029] In this embodiment, the sealing performance of the tower body 100 is ensured by mainly setting a sealing door 200 to shield the inspection port, and the opening and closing of the sealing door 200 is mainly driven by a connecting rod mechanism composed of a wrench 201, a ratchet column 202, a ratchet wheel 203, a connecting rod 204 and a fixing member 204a. The specific working principle is as follows: directly pull the wrench 201 downward, and the wrench 201 directly pushes the lower end of the sealing door 200 into the inspection port through the connecting rod 204 during the movement. When the lower part of the sealing door 200 is subjected to an inward force, the upper end of the sealing door 200 will protrude outward. The premise of this movement is that the two ends of the sealing door 200 are connected to the inspection port through a rotating shaft, so that the sealing door 200 is in an open state during the entire rotation. A ratchet column 202 is provided in the wrench 201, and the spring 202b can be used to make the ratchet column 202 clamped on the ratchet 203, so that the wrench 201 can remain in a fixed state at all times, preventing accidental injury caused by the reset of the wrench 201 due to the weight of the sealing door 200.
